Description

Lit climatisé comprenant un matelas ayant une couche perméable à l'air Air-conditioned bed comprising a mattress having an air permeable layer
La présente invention concerne le domaine de la literie et notamment celui des lits climatisés.The present invention relates to the field of bedding and in particular that of air-conditioned beds.
De tels lits climatisés sont déjà connus dans l'état de la technique. On connaît le document EP O 862 901 qui décrit un dispositif comprenant des systèmes thermoélectriques visant à chauffer ou à refroidir un matelas d'un incubateur à nouveaux-nés. Par ailleurs, le document US 2004/093050 décrit un dispositif thérapeutique visant à refroidir le corps d'une personne allongée sur un matelas, comprenant un système à cavités gonflables associé à un système externe d'air conditionné.Such air-conditioned beds are already known in the state of the art. EP 0 862 901 discloses a device comprising thermoelectric systems for heating or cooling a mattress of a newborn incubator. Furthermore, US 2004/093050 discloses a therapeutic device for cooling the body of a person lying on a mattress, comprising an inflatable cavity system associated with an external air conditioning system.
Ces lits climatisés étant notamment destinés au domaine médical, ils ne présentent généralement pas le confort attendu pour une utilisation domestique quotidienne.These air-conditioned beds being particularly intended for the medical field, they do not generally have the expected comfort for daily household use.
Qui plus est, il existe un besoin de maintenir une ambiance climatique à température contrôlée dans les lits. Cette climatisation du lit vaut d'ailleurs aussi bien pour réchauffer l'ambiance interne que pour la rafraîchir.Moreover, there is a need to maintain a climate-controlled climate in the beds. This air conditioning of the bed is also good for warming the internal atmosphere to cool it.
Un but de la présente invention est de fournir un lit climatisé améliorant le confort de l'utilisateur.An object of the present invention is to provide an air-conditioned bed improving the comfort of the user.
La présente invention atteint son but par le fait que le lit climatisé selon l'invention comprend : - une source d'air conditionné à une température prédéterminée ;The present invention achieves its object by the fact that the air-conditioned bed according to the invention comprises: a source of conditioned air at a predetermined temperature;
- un matelas comprenant une couche supérieure formée d'un matériau perméable à l'air ;a mattress comprising an upper layer formed of a material that is permeable to air;
- des premiers moyens de soufflerie pour envoyer de l'air conditionné par la source dans la couche supérieure du matelas, de telle manière que la couche supérieure du matelas diffuse l'air conditionné.- First blower means for sending air conditioning from the source in the upper layer of the mattress, so that the upper layer of the mattress diffuses conditioned air.
Selon l'invention, la source d'air conditionné est apte à générer de l'air chaud ou de l'air froid en fonction du besoin de l'utilisateur. On comprend que l'air conditionné diffuse vers l'utilisateur à travers la couche supérieure du matelas et plus précisément à travers la face supérieure de la couche supérieure du matelas, qui correspond à la face supérieure du matelas.According to the invention, the source of conditioned air is able to generate hot air or cold air depending on the need of the user. We understand that the air conditioning diffuses towards the user through the upper layer of the mattress and more precisely through the face upper layer of the mattress, which corresponds to the upper face of the mattress.
De manière préférentielle, la couche supérieure du matelas est formée dans un matériau poreux, tel par exemple un matériau fibreux. On comprend donc que la présente invention permet de maintenir les conditions de confort thermique de la ou des personnes installées et/ou couchées dans le lit.Preferably, the upper layer of the mattress is formed in a porous material, such as for example a fibrous material. It is therefore understood that the present invention allows to maintain the thermal comfort conditions of the person or persons installed and / or lying in the bed.
Avantageusement, le lit climatisé selon l'invention comporte en outre une couverture comprenant un premier drap apte à couvrir un utilisateur et un deuxième drap, le premier drap étant perméable à l'air, et des seconds moyens de soufflerie pour amener de l'air conditionné entre les deux draps de la couverture.Advantageously, the conditioned bed according to the invention further comprises a cover comprising a first sheet capable of covering a user and a second sheet, the first sheet being permeable to air, and second means of blowing to bring air conditioned between the two sheets of the blanket.
On comprend donc que l'air conditionné est diffusé vers l'utilisateur à la fois au travers de la couche supérieure du matelas et au moins au à travers du premier drap de la couverture.It is therefore understood that the air conditioning is diffused to the user both through the upper layer of the mattress and at least through the first sheet of the cover.
Un intérêt de l'invention porte sur le contrôle de l'ambiance thermique au plus près du corps et en faisant que l'ambiance intérieure du lit puisse être fixée à une température significativement différente de la température de la pièce dans laquelle le lit est installé. La climatisation au plus près du corps dans un volume limité permet de créer un microclimat confortable dans une pièce dont la température peut être significativement différente, ce qui permet de réduire très fortement les consommations d'énergie associées au chauffage et au rafraîchissement. Enfin la présente invention vise à créer un flux aéraulique doux qui évite les nuisances sonores habituelles des systèmes de ventilation. Le concept crée un microclimat confortable à l'intérieur du volume délimité par le drap supérieur, la literie et le matelas. Ce concept est applicable à un lit aussi bien à une place qu'à deux places. De manière préférentielle, le deuxième drap de la couverture est perméable à l'air de telle sorte que le flux d'air soit essentiellement dirigé vers l'utilisateur.An interest of the invention relates to the control of the thermal environment closer to the body and by making the interior environment of the bed can be set at a temperature significantly different from the temperature of the room in which the bed is installed . Air conditioning closer to the body in a limited volume can create a comfortable microclimate in a room whose temperature can be significantly different, which can greatly reduce the energy consumption associated with heating and cooling. Finally, the present invention aims to create a gentle air flow that avoids the usual noise nuisance ventilation systems. The concept creates a comfortable microclimate inside the volume defined by the top sheet, bedding and mattress. This concept is applicable to a single bed as well as two places. Preferably, the second sheet of the cover is permeable to air so that the flow of air is essentially directed towards the user.
Selon une variante avantageuse, le deuxième drap est réalisé dans un matériau apte à réfléchir le rayonnement infrarouge. On comprend que le matériau réfléchissant dans l'infrarouge sert l'hiver à confiner la chaleur émise par le corps de l'utilisateur et limite ainsi le besoin en chauffage, tandis que l'été, au contraire, le matériau sépare l'ambiance rayonnante à température plus élevée de la pièce dans laquelle se trouve le lit, de l'ambiance plus fraîche existant à l'intérieur du volume délimité par la couverture et le matelas. Avantageusement, le matelas comporte en outre une couche intermédiaire disposée en dessous de la couche supérieure, ladite couche intermédiaire comportant des moyens de distribution aptes à distribuer l'air conditionné provenant des premiers moyens de soufflerie dans tout ou partie de la couche supérieure.According to an advantageous variant, the second sheet is made of a material capable of reflecting infrared radiation. It is understood that the reflective material in the infrared is used in winter to contain the heat emitted by the body of the user and thus limits the need for heating, while in summer, on the contrary, the material separates the radiating atmosphere at higher temperature from the room in which the bed is located, the cooler atmosphere existing inside the volume delimited by the blanket and the mattress. Advantageously, the mattress further comprises an intermediate layer disposed below the upper layer, said intermediate layer having distribution means adapted to distribute the conditioned air from the first blower means in all or part of the upper layer.
On conçoit notamment que la distribution homogène du flux d'air conditionné sur toute la surface de la couche supérieure permet d'améliorer encore le confort de l'utilisateur.In particular, it can be seen that the homogeneous distribution of the conditioned air flow over the entire surface of the upper layer makes it possible to further improve the comfort of the user.
De manière préférentielle, les moyens de distribution comportent une pluralité de canaux ménagés dans la couche intermédiaire.Preferably, the distribution means comprise a plurality of channels formed in the intermediate layer.
Avantageusement, les moyens de distribution forment un réseau maillé ménagé dans une surface supérieure de la couche intermédiaire. De manière préférentielle, le réseau maillé forme un quadrillage. Ces canaux sont destinés à permettre la circulation de l'air conditionné dans tout le réseau maillé et préférentiel lement sur pratiquement toute la surface supérieure de la couche intermédiaire. On comprend donc que l'air circulant dans les canaux peut diffuser vers la couche supérieure du matelas grâce au fait que ladite couche supérieure recouvre les canaux.Advantageously, the distribution means form a mesh network formed in an upper surface of the intermediate layer. Preferably, the mesh network forms a grid. These channels are intended to allow the circulation of conditioned air throughout the mesh network and preferably on substantially the entire upper surface of the intermediate layer. It is therefore understood that the air flowing in the channels can diffuse towards the upper layer of the mattress thanks to the fact that said upper layer covers the channels.
Avantageusement, les seconds moyens de soufflerie comportent un tube reliant la couche intermédiaire du matelas à la couverture, afin d'amener l'air conditionné entre les premier et deuxième draps de la couverture.Advantageously, the second blower means comprise a tube connecting the intermediate layer of the mattress to the cover, in order to bring conditioned air between the first and second sheets of the cover.
Le tube est préférentiel lement connecté à l'un des canaux du réseau maillé de la couche intermédiaire permettant ainsi de faire circuler de l'air conditionné depuis la couche intermédiaire vers l'intérieur de la couverture.The tube is preferably connected to one of the channels of the mesh network of the intermediate layer thus making it possible to circulate conditioned air from the intermediate layer towards the inside of the cover.
Avantageusement, les premiers moyens de soufflerie comportent deux conduites reliées au réseau maillé de part et d'autre de la largeur du matelas.Advantageously, the first blower means comprise two ducts connected to the mesh network on either side of the width of the mattress.
De manière préférentielle, le lit climatisé comporte en outre des moyens pour régler le débit de l'air circulant dans chacune des deux conduites. De la sorte, il est possible de régler le flux d'air diffusant sur les côtés gauche et droite du matelas.Preferably, the conditioned bed further comprises means for adjusting the flow rate of the air flowing in each of the two pipes. In this way, it is possible to adjust the airflow diffusing on the left and right sides of the mattress.
Ainsi, deux utilisateurs du lit climatisé selon l'invention peuvent régler indépendamment le flux d'air diffusant dans le matelas. De manière préférentielle, les conduites sont réalisées en élastomère souple de manière à diminuer le bruit lié à la circulation de l'air conditionné.Thus, two users of the air-conditioned bed according to the invention can independently adjust the flow of air diffusing into the mattress. Preferably, the pipes are made of flexible elastomer so as to reduce the noise associated with the circulation of the conditioned air.
Avantageusement, la source d'air conditionné comporte une pompe à chaleur réversible, permettant de générer de l'air chaud ou de l'air froid. De manière préférentielle, la pompe à chaleur est une micro-pompe à chaleur réversible qui est installée dans un tiroir amovible pour faciliter les opérations de maintenance nécessaires. De préférence, l'air est filtré et la diffusion de la fraîcheur ou de la chaleur est réglable.Advantageously, the air conditioning source comprises a reversible heat pump, for generating hot air or cold air. Preferably, the heat pump is a reversible heat pump micro-pump which is installed in a removable drawer to facilitate the necessary maintenance operations. Preferably, the air is filtered and the diffusion of freshness or heat is adjustable.

Le lit climatisé 10 selon l'invention comporte une source d'air conditionné comprenant une micro-pompe à chaleur 12 intégrée dans un tiroir amovible 14 situé sous le lit 10.To describe the air-conditioned bed 10 according to the present invention, reference is first made to FIG. 1. The air-conditioned bed 10 according to the invention comprises an air-conditioning source comprising a heat pump 12 integrated in a removable drawer. 14 located under the bed 10.
Les pompes à chaleur réversibles, permettant de générer de l'air chaud ou de l'air froid, sont déjà connues par ailleurs et leur fonctionnement ne sera pas repris ici.Reversible heat pumps, for generating hot air or cold air, are already known elsewhere and their operation will not be repeated here.
Le lit climatisé 10 comporte un matelas 16 formé d'une couche supérieure 18 apte à supporter un utilisateur 11, et d'une couche intermédiaire 20 située en dessous de la couche supérieure 18.The conditioned bed 10 comprises a mattress 16 formed of an upper layer 18 adapted to support a user 11, and an intermediate layer 20 located below the upper layer 18.
La couche supérieure 18 est réalisée de préférence dans un matériau fibreux.The upper layer 18 is preferably made of a fibrous material.
Le lit climatisé 10 comporte en outre des premiers moyens de soufflerie comprenant au moins un ventilateur et deux conduites 22 reliées à la couche intermédiaire 20.The conditioned bed 10 further comprises first blower means comprising at least one blower and two ducts 22 connected to the intermediate layer 20.
La couche intermédiaire 20 comporte des moyens de distribution 24 aptes à distribuer l'air conditionné provenant de la micro-pompe 12 sur toute la surface de la couche supérieure 18. Ensuite, l'air est diffusé au travers de la couche supérieure 18, qui occupe préférentiellement le tiers de l'épaisseur total du matelas 16.The intermediate layer 20 comprises distribution means 24 able to distribute the conditioned air coming from the micro-pump 12 over the entire surface of the upper layer 18. Then, the air is diffused through the upper layer 18, which preferably occupies one third of the total thickness of the mattress 16.
La couche supérieure 18 du matelas 10 est dotée de propriétés mécaniques et de porosité assurant le double maintien du confort mécanique et d'une distribution d'air maîtrisée.The upper layer 18 of the mattress 10 is provided with mechanical properties and porosity ensuring the dual maintenance of mechanical comfort and a controlled air distribution.
Selon un mode préféré de réalisation de l'invention, le lit climatisé 10 comporte en outre une couverture 26 comprenant un premier drap 28 perméable à l'air, un deuxième drap 30 imperméable à l'air, et un troisième drap 32 extérieur.According to a preferred embodiment of the invention, the air-conditioned bed 10 further comprises a cover 26 comprising a first sheet 28 permeable to air, a second sheet 30 impermeable to air, and a third sheet 32 outside.
Les premier et deuxième draps sont fixés ensemble par leurs côtés de manière à délimiter une alvéole interne 33.The first and second sheets are fixed together by their sides so as to delimit an internal cell 33.
Comme on le voit sur les figures 1 et 2, la couche intermédiaire 20 est reliée à l'alvéole 33 de la couverture 26 par l'intermédiaire d'un tube souple 34. Ce tube 34 permet d'amener l'air depuis la couche intermédiaire 20 vers l'alvéole 33. Par ailleurs, ce tube 34 est doublement démontable d'une part vis-à-vis de la couverture 26 pour permettre son lavage aisé et, d'autre part, vis-à-vis d'un raccord 36. Les premier et deuxième draps 28,30 forment enveloppe et sont constitués de tissu.As seen in FIGS. 1 and 2, the intermediate layer 20 is connected to the cell 33 of the cover 26 via a flexible tube 34. This tube 34 can bring the air from the intermediate layer 20 to the cell 33. Moreover, this tube 34 is doubly removable on the one hand vis-à-vis the cover 26 to allow easy washing and, on the other hand, vis-à-vis a connector 36. The first and second sheets 28,30 form envelope and are made of fabric.
De manière avantageuse, le premier drap 28 est constitué de coton, matériau perméable à l'air.Advantageously, the first sheet 28 is made of cotton, a material that is permeable to air.
Néanmoins, on peut utiliser tout autre type de tissu perméable à l'air.Nevertheless, any other type of breathable fabric can be used.
Le deuxième drap 30, fabriqué dans un matériau lavable, dispose de propriétés particulières et peut être soit très peu perméable à l'air, et / ou à la fois très peu perméable à l'air et réfléchissante dans l'infrarouge.The second sheet 30, made of a washable material, has particular properties and can be either very low in the air, and / or both very low breathability and reflective in the infrared.
Ceci permet de diffuser l'air de manière douce avec des vitesses typiquement inférieures à 0,1 m/s à la fois à travers la surface où repose l'utilisateur, c'est-à-dire le matelas diffusant et la literie qui sont perméables à l'air et via le premier drap 28 diffusant qui complète la micro enceinte climatique et qui lui aussi diffuse l'air rafraîchi ou réchauffé à travers l'ensemble de sa surface, côté interne du couchage qui forme alors micro-enceinte climatique.This makes it possible to diffuse the air in a gentle manner with speeds typically less than 0.1 m / s at a time through the surface where the user rests, that is to say the diffusing mattress and the bedding which are permeable to the air and via the first diffusing sheet 28 which completes the micro climatic chamber and which also diffuses the air cooled or heated through its entire surface, the inner side of the coating which then forms climatic micro-chamber.
La figure 3 montre à titre d'exemple la structure de la couche intermédiaire 20 du matelas 16 dotée sur sa partie supérieure d'un réseau maillé de distribution 38 avec des canaux horizontaux de distribution primaire 40 et 42 symétriques par rapport à l'axe longitudinal central du matelas 16 et alimenté par des première et seconde conduites verticales d'arrivée d'air symétriques 44 et 46.FIG. 3 shows, by way of example, the structure of the intermediate layer 20 of the mattress 16 provided on its upper part with a meshed distribution network 38 with horizontal primary distribution channels 40 and 42 that are symmetrical with respect to the longitudinal axis central of the mattress 16 and powered by first and second symmetrical vertical air intake pipes 44 and 46.
Comme on le voit sur la figure 3, les canaux du réseau maillé de distribution 38 sont avantageusement ménagés dans la couche intermédiaire 20. La couche intermédiaire 20 du matelas 16 constituant préférentiellement les deux tiers de l'épaisseur totale du matelas 16 est fabriquée dans un matériau de type polyuréthanne ou plus généralement d'une mousse à propriétés mécaniques adaptées et présentant une certaine rigidité. La symétrie des première et seconde conduites verticales d'arrivée d'air 44 et 46 et des canaux primaires 40 et 42 permettent, pour un matelas à deux places, de moduler le débit d'air du côté droit et du côté gauche du matelas 16 en permettant de modifier les conditions de climatisation lorsque deux personnes souhaitent régler différemment les conditions de confort dans le lit. II en va de même pour le premier drap 28 pour les lits à deux places où une couture centrale non représentée peut être formée entre les premier et deuxième draps délimitant deux sous-alvéoles longitudinales droite et gauche.As can be seen in FIG. 3, the channels of the meshed distribution network 38 are advantageously formed in the intermediate layer 20. The intermediate layer 20 of the mattress 16 preferably constituting two-thirds of the total thickness of the mattress 16 is manufactured in a material of the polyurethane type or more generally of a foam with suitable mechanical properties and having a certain rigidity. The symmetry of the first and second vertical air intake pipes 44 and 46 and the primary channels 40 and 42 make it possible, for a two-seater mattress, modulate the flow of air on the right side and the left side of the mattress 16 by changing the conditions of air conditioning when two people want to adjust the different conditions of comfort in the bed. It is the same for the first sheet 28 for two-seater beds where a not shown central seam can be formed between the first and second sheets delimiting two right and left longitudinal sub-cells.
La figure 4 montre un détail des moyens de distribution 24 où la seconde conduite 46 alimente le réseau maillé 38 en forme de quadrillage comprenant par exemple des canaux 48,50,52.FIG. 4 shows a detail of the distribution means 24 where the second conduit 46 supplies the grid network 38 in the form of a grid, for example comprising channels 48, 50, 52.
La figure 5 montre une coupe partiellement arrachée de la couche supérieure 18. Cette couche 18 est constituée d'un matériau fibreux, à résistance mécanique telle que le poids de la ou des personnes couchées n'entraîne pas l'écrasement total de cette couche supérieure 18 afin de permettre une circulation d'air même sous les surfaces du corps directement en contact avec la literie.FIG. 5 shows a partially cut-away section of the upper layer 18. This layer 18 is made of a fibrous material, with mechanical strength such that the weight of the person or persons lying down does not result in the total crushing of this upper layer. 18 to allow air circulation even under the surfaces of the body directly in contact with the bedding.
En effet, cette propriété permet d'apporter ou d'extraire de la chaleur sur les parties en contact qui sont toujours les parties inconfortables parce que la surface est trop chaude ou trop froide. Sur les parties de la couche supérieure du matelas qui ne sont pas en contact avec le corps de l'utilisateur, l'air diffuse doucement de manière quasi isotrope soit en provenance du matelas diffusant 10, soit en provenance du drap diffusant 26. Contrairement aux lits déjà connus, il faut se couvrir du drap et non pas se découvrir pour obtenir les conditions de confort. Ceci permet de comprendre ce qu'est la création d'un microclimat contrôlé.Indeed, this property makes it possible to bring or extract heat on the parts in contact which are always the uncomfortable parts because the surface is too hot or too cold. On the parts of the upper layer of the mattress that are not in contact with the body of the user, the air diffuses slowly almost isotropically either from the diffusing mat 10 or from the diffusing sheet 26. Unlike already known beds, it is necessary to cover oneself of the sheet and not to be discovered to obtain the conditions of comfort. This helps to understand what is the creation of a controlled microclimate.
A l'aide des figures 6 et 7, on va maintenant décrire plus en détail la micro-pompe à chaleur 12. Le tiroir 14 contenant la micro-pompe à chaleur 12 est intégré dans la partie d'un sommier 54 qui est située en pied du lit 10.With the aid of FIGS. 6 and 7, the micro-heat pump 12 will now be described in more detail. The slide 14 containing the micro-heat pump 12 is integrated in the part of a bed base 54 which is located in foot of the bed 10.
La micro-pompe à chaleur 12 comporte un ou deux compresseurs hermétiques (non représentés ici), fonctionnant avantageusement en 24 V courant continu, intégrés dans un caisson isolé phoniquement 56. Dans un compartiment adjacent 58 se trouve un premier échangeur frigorigène / air 60 qui, en mode rafraîchissement, fonctionne en condenseur et qui reçoit l'air à partir d'un ventilateur 62 qui aspire l'air de l'extérieur par une ouverture 64. Ce flux d'air passe à travers le compartiment isolant 56 des compresseurs et sort par l'ouverture 66 représentée figure 7, ce qui permet de refroidir les compresseurs. La micro-pompe à chaleur 12 comporte en outre un caisson 68 où se trouvent successivement un système de filtration 70 à l'aval d'une ouverture 72 et à l'amont du ventilateur 74, qui est caché par le système de filtration 70, puis un second échangeur frigorigène / air 76 qui en mode rafraîchissement fonctionne comme un évaporateur et refroidit l'air filtré entrant.The micro-heat pump 12 comprises one or two hermetic compressors (not shown here), advantageously operating in 24 V direct current, integrated in a phonically insulated box 56. In an adjacent compartment 58 is a first refrigerant / air exchanger 60 which , in refresh mode, works in a condenser and which receives the air from a fan 62 which draws air from the outside through an opening 64. This flow of air passes through the insulating compartment 56 of the compressors and leaves through the opening 66 represented in FIG. 7, which makes it possible to cool the compressors. The micro-heat pump 12 further comprises a box 68 in which are successively a filtration system 70 downstream of an opening 72 and upstream of the fan 74, which is hidden by the filtration system 70, then a second refrigerant / air exchanger 76 which in cooling mode operates as an evaporator and cools the incoming filtered air.
L'air entrant par l'ouverture 72 passe ensuite au travers du système de filtration 70 pour successivement piéger les poussières, les particules diverses puis les pollens, une dernière couche en charbon actif peut aussi avantageusement piéger les molécules odorantes. Ce système de filtration 70 est amovible et peut facilement être changé sans ouvrir le tiroir 14, par une simple ouverture située dans la partie supérieure du tiroir intégré dans le sommier.The air entering through the opening 72 then passes through the filtration system 70 to successively trap dust, various particles and pollen, a last layer of activated carbon can also advantageously trap odor molecules. This filtration system 70 is removable and can easily be changed without opening the drawer 14, by a single opening in the upper part of the integrated drawer in the bed frame.
Un automatisme utilisant la valeur de l'écart de température entre la température de sortie d'air du second échangeur 76 et la température de surface dudit échangeur 76 permet de diagnostiquer le colmatage du filtre. Plus cet écart de température grandit, pour une vitesse de ventilation fixée, plus le filtre est en train de se colmater. Au-delà d'un écart, typiquement de 15 0C, un signal est donné à l'utilisateur pour qu'il change le filtre. Comme on le voit sur la figure 7, l'air ainsi filtré puis refroidi ou réchauffé par Péchangeur 76 est ensuite repris par un ventilateur 78 qui va le faire circuler dans l'ensemble de conduites souples et isolantes phoniquement 22. Ces tuyauteries souples sont avantageusement fabriquées en matériau élastomère souple ayant un fort amortissement du son pour éviter les transferts de vibration et la conduction phonique solidienne.An automatism using the value of the temperature difference between the air outlet temperature of the second exchanger 76 and the surface temperature of said exchanger 76 makes it possible to diagnose clogging of the filter. The more this temperature difference increases, for a fixed ventilation speed, the more the filter is clogging. Beyond a deviation, typically 15 0 C, a signal is given to the user to change the filter. As can be seen in FIG. 7, the air thus filtered and then cooled or heated by the exchanger 76 is then taken up by a fan 78 which will circulate it through the set of flexible and acoustically insulating pipes 22. These flexible pipes are advantageously made of flexible elastomeric material with high sound damping to prevent vibration transfer and solid sound conduction.
Pour ajuster les débits de manière modulée par chaque occupant du lit à deux places, deux ventilateurs 80 et 82 assurent la circulation d'air dans le réseau de conduites 22 puis respectivement dans la première conduite d'entrée verticale 44 pour le ventilateur 80 et la seconde conduite d'entrée verticale 46 pour le ventilateur 82. Comme déjà présenté à la figure 5, ce flux d'air air est ensuite diffusé dans le réseau maillé 38 via les canaux de distribution primairesTo adjust the flow rates modulated by each occupant of the double bed, two fans 80 and 82 provide air circulation in the network of pipes 22 and respectively in the first vertical inlet pipe 44 for the fan 80 and the second vertical inlet duct 46 for the fan 82. As already shown in FIG. 5, this air air flow is then diffused in the mesh network 38 via the primary distribution channels
40 et 42 formés dans la structure en mousse rigide de la couche intermédiaire 20 et enfin à travers la couche supérieure 18 diffusante et la couverture 26 diffusante.40 and 42 formed in the rigid foam structure of the intermediate layer 20 and finally through the upper diffusing layer 18 and the cover 26 diffusing.
Cette conception de fractionner la ventilation en plusieurs ventilateurs permet avantageusement de limiter drastiquement le bruit et permet aussi la modulation du débit sur les parties droite et gauche d'un lit à deux places selon l'invention. Comme indiqué figure 7, pour retirer le tiroir 14, il suffit de désaccoupler la conduite 22 de la paroi verticale 84 du tiroir 14, permettant ainsi de faciliter les éventuelles opérations de maintenance.This design of splitting the ventilation into several fans advantageously allows drastically limit the noise and also allows the modulation of the flow on the right and left parts of a double bed according to the invention. As shown in Figure 7, to remove the drawer 14, it is sufficient to uncouple the pipe 22 of the vertical wall 84 of the slide 14, thus facilitating any maintenance operations.
Pour passer du mode rafraîchissement au mode chauffage, il est utilisé le procédé connu d'une vanne à quatre voies qui inversera le sens de circulation du fluide frigorigène dans les échangeurs, le premier échangeur 60 fonctionnant alors en évaporateur pour absorber la chaleur en provenance de l'air de la pièce et le second échangeur 76 fonctionnant alors en condenseur pour réchauffer l'air.To switch from the cooling mode to the heating mode, the known method of a four-way valve is used which will reverse the direction of circulation of the refrigerant in the exchangers, the first exchanger 60 then operating as an evaporator to absorb the heat coming from the air in the room and the second heat exchanger 76 then operating in a condenser to heat the air.
L'air est ensuite mis en circulation dans le réseau de canaux et diffusant via le matelas diffusant 10 et le drap diffusant 26 comme décrit précédemment.The air is then circulated in the channel network and diffusing via the diffusing mat 10 and the diffusing sheet 26 as previously described.
Le système de filtration 86 représenté figure 7, placé à l'entrée du premier échangeur 60 est identique au système de filtration 70 décrit précédemment. La source d'air conditionné 12 est contrôlée à partir d'un tableau de commande 88 ou avantageusement d'une télécommande dont les interrupteurs de commande sont présentés dans leur principe à la figure 8.The filtration system 86 shown in FIG. 7 placed at the inlet of the first exchanger 60 is identical to the filtration system 70 described above. The air-conditioning source 12 is controlled from a control panel 88 or advantageously from a remote control whose control switches are presented in principle in FIG. 8.
Un bouton 90 permet la mise en marche et l'arrêt des ventilateurs 80,82 et aussi de choisir un ou plusieurs niveaux de ventilation. En dessous de ce bouton de commande sont disponibles deux interrupteurs 92 et 94 précisant droite et gauche, pour activer ou inhiber le système de ventilation des parties droite ou gauche d'un lit à deux places. Un bouton 96 est un bouton marche/arrêt pour le chauffage, le bouton 98 un bouton marche/arrêt pour le rafraîchissement. L'enclenchement du bouton 96 inhibe l'enclenchement du bouton 98 et vice-versa. Des voyants 100 et 102 indiquent que les filtres, respectivement 70 et 86, doivent être changés. Lorsque l'écart de température entre la surface de l'évaporateur et l'air sortant est supérieur à un seuil défini, par exemple 1O0K, les voyants 100 ou 102 s'allument et, de plus, le fonctionnement de la micro pompe à chaleur réversible 12 est inhibé jusqu'à ce que les filtres soient changés.A button 90 allows the starting and stopping of the fans 80,82 and also to choose one or more levels of ventilation. Below this control button are available two switches 92 and 94 specifying right and left, to activate or inhibit the ventilation system of the left or right parts of a double bed. A button 96 is an on / off button for heating, the button 98 an on / off button for cooling. The engagement of the button 96 inhibits the engagement of the button 98 and vice versa. LEDs 100 and 102 indicate that the filters, respectively 70 and 86, must be changed. When the temperature difference between the surface of the evaporator and the outgoing air is greater than a defined threshold, for example 1O 0 K, the lights 100 or 102 come on and, in addition, the operation of the micro pump Reversible heat 12 is inhibited until the filters are changed.
Un bouton 104 qui commande une minuterie et une horloge permettant de déclencher le pré-conditionnement en chauffage ou en rafraîchissement avant l'entrée dans le lit. Le tableau de commande ou la télécommande 88 offre à l'utilisateur les possibilités suivantes : ventilation seule en activant le bouton 90 et avec différents niveaux de ventilation, le rafraîchissement associé à la ventilation par l'activation du bouton 96, le chauffage par l'activation du bouton 98. L'activation de ces deux boutons enclenche obligatoirement la ventilation au premier niveau.A button 104 which controls a timer and a clock to trigger the pre-conditioning heating or cooling before entering the bed. The control panel or the remote control 88 offers the user the following possibilities: ventilation only by activating the button 90 and with different levels of ventilation, the cooling associated with the ventilation by the activation of the button 96, the heating by the activation of the button 98. The activation of these two buttons necessarily triggers the ventilation at the first level.
Ces fonctions sont déclenchées sur l'ensemble du lit par défaut et l'utilisateur peut inhiber la ventilation du côté droit ou gauche en appuyant respectivement sur les boutons 92 et 94. Enfin, le bouton horloge minuterie 104 permet à l'utilisateur de préparer le lit dans les conditions de température qu'il souhaite. These functions are triggered on the entire default bed and the user can inhibit ventilation on the right or left side by respectively pressing the buttons 92 and 94. Finally, the timer clock button 104 allows the user to prepare the reads in the desired temperature conditions.
