Abstract
One or more piezoelectric devices cool or heat a thermally-conductive basin. The basin is sized, shaped and arranged to receive two or more food serving trays. In a preferred embodiment, the food serving trays are sized, shaped and arranged to provide an air gap between the tray and the thermally-conductive basin so that the tray is cooled by convection and radiation but not conduction.
Description
-
FIG. 1 is a perspective view of a prior art thermoelectric cooler orchiller 1 designed to cool small volumes of condiments, garnishes or dairy products. The chiller uses a piezoelectric Peltierdevice 3 located in alower chamber 4 of thechiller 1. The cold side of thepiezoelectric device 3 is thermally coupled to thebottom surface 5 of a thin, thermally-conductivefood holding tray 6. Thefood holding tray 6 fits precisely into a thermallyconductive basin 11 that lies just outside thetray 6. -
FIG. 2 is a cross-sectional diagram of the prior art chiller shown inFIG. 1 taken across section lines 2-2. Thepiezoelectric device 3 has its cold side attached to aheat sink 8 thermally coupled to thebottom 5 of thefood holding tray 6. A hotside heat sink 9 is provided with air cooling fins to facilitate the transfer of heat absorbed from the cold side, away from thethermoelectric device 3 hot side. - A problem with prior art thermoelectric coolers or chillers shown in
FIG. 1 andFIG. 2 is that thefood holding tray 6 is sized or configured to snugly fit into a only a custom-sizedinsert basin 11 in order to maximize heat conduction. A second and related problem with the prior art thermoelectric chillers shown inFIG. 1 andFIG. 2 is that they cool a food insert tray exclusively by thermal conduction and since thefood holding tray 6 is typically on the order of an eighth inch thick, evenly cooling the tray contents from top to bottom is problematic. A third problem is that they are able to use only one thermally-conductive food serving tray, i.e., the one provided by the manufacturer. - While heat conduction can transfer heat between the food storage tray 6 and the
thermoelectric device 3, conductive heat transfer tends to result in an uneven heat absorption through-out thebasin 11. Portions of thebasin 11 nearest the Peltierdevice 3 tend be very cold whereas portions of the basin away from the Peltier device tend to be relatively warm, especially when thebasin 11 is fitted tightly against a food holding tray filled with relatively warm food products. The reliance on only thermal conduction to transfer heat between the food products and the Peltier refrigeration device tends to create significant temperature gradients between the bottom of thetray 5 and theopen top 7. A thermoelectric cooler that would accept industry-standard inserts and which would provide a more uniform temperature through-out a food holding tray would be an improvement over the prior art. -
FIG. 1 is a perspective view of a prior art thermoelectric cooler; -
FIG. 2 is a cross section of the prior art thermoelectric cooler shown inFIG. 1 ; -
FIG. 3 is a perspective view of a thermoelectric view that shows the construction of the cooler; -
FIG. 4 is a left-side view of a thermoelectric cooler having air gaps between the sides and bottom of a food holding tray and a temperature controlled basin; -
FIG. 5 is a front view of the thermoelectric cooler shown inFIG. 3 ; and -
FIG. 6 is a perspective view of the thermoelectric cooler showing a variable speed blower and duct to route room air over the hot-side heat sink of the thermoelectric device. -
FIG. 3 is a perspective view of a temperature-controlledfood storage unit 10. Thefood storage unit 10 is comprised of acabinet 12, which supports, encloses and insulates a thermally-conductive basin 14 for storing food products and/or thermally-conductive food serving trays. Thebasin 14 has anopen top 16, four thermally-conductiveorthogonal sides 18 and a thermally-conductive bottom 20. Aplanar top 21 around the periphery of thecabinet 12 supports a thermally-conductive food storage container ortray 36, which hangs into the open volume of the thermally-conductive basin 14 from the planartop surface 21. Arefrigeration unit 24 is thermally coupled to thebottom 20 of thebasin 14. -
FIG. 4 is a side view of the temperature-controlledfood storage unit 10 through section lines 4-4. Thefood storage tray 36 shown inFIG. 4 has anopen top 38, sloping or taperedsides 40 that imbue thefood storage tray 36 with the shape of an inverted truncated pyramid with aplanar bottom 42. Since thesidewalls 18 of thebasin 14 are orthogonal to the planar, andhorizontal basin bottom 20, thetapered sides 40 of thefood storage tray 36 create a generally pyramid-shaped air gap 44 between thesides 40 and thesidewalls 18 of the basin. - The length of the
sidewalls 18 determines the location of the bottom of thetray 42 above the bottom of thebasin 20. The sidewall length thus effectively determines the space between thebasin bottom 20 and thetray bottom 42. The open space between thetray bottom 42 and thebasin bottom 20 defines a second, substantiallyrectangular air gap 46. - The
air gap 44 and theair gap 46 allow air currents to exist between the sidewalls and bottom of the food storage try 36 and the side walls and bottom of thebasin 14. The air gaps thus allow heat transfer by convection currents. - The air gaps also allow heat to be radiated from warm surfaces to cold surfaces. The air gaps thus allow heat transfer by radiation. Except for very small amounts of heat transfer that can take place between the top edges of the
food storage tray 36, which rest on thetop surface 21 of thecabinet 12, heat transfer between thefood storage tray 36 and thebasin 14 is by convection and radiation but not by conduction. Transferring heat by convection and radiation but not conduction is believed to provide a more uniform heat dissipation from thefood storage tray 36, which yields a more uniform temperature gradient inside thetray 36. - Refrigerating the
basin 14 can be accomplished by having thelower surface 22 of thebottom 20 of thebasin 14 thermally connected to a coldside heat sink 26, below which is a solid state heat pump or Peltier device. Peltier devices and their operation are well known to those of ordinary skill in the art. A description of their characteristics and operation is omitted for brevity, they are however considered herein to be solid-state heat pumps. - Air is preferably blown across a finned, hot-
side heat sink 28 that dissipates heat from the hot side of a Peltier device. Dissipating heat from the hot side decreases the Peltier device cold side temperature. As the Peltier device cold side gets colder, the temperature of the metal surrounding the cold side of the Peltier device drops, allowing the colder metal to absorb heat. -
Temperature sensors 49 are coupled to thelower surface 22 of the basin to provide an electrically measurable representation of the temperature of thebasin 14, to a controller orcentral processing unit 32. The controller orCPU 32 reads thesensors 49 and in response thereto, it modulates the electric power provided to the Peltier device to keep the measured temperature within a preferred operating range. - In one embodiment, the controller/
CPU 32 measures a voltage across a temperature-dependent transistor. In another embodiment, the controller/CPU reads the electrical resistance of a thermistor. The temperatures of thesensors 49 thus indicate a temperature of at least the lower surface of thebasin 22. By adjusting the power provided to the Peltier device, the temperature inside the basin can be effectively controlled. -
FIG. 5 is a cross-sectional diagram of the temperature-controlledfood storage unit 10 taken from in front of the unit.FIG. 5 shows two, side-by-sidefood storage trays 36 suspended in thecabinet 12. Thecontainer 36 on the left is depicted as being wider than the container on the right 36 to demonstrate that the temperature controlledfood storage unit 10 can be operated withmultiple trays 36, as well astrays 36 of different sizes and/or shapes. - In
FIG. 5 , bothtrays 36 haveopen tops 38 and taperedsides 40. Bothtrays 36 haveplanar bottoms 42 located above thebottom 20 of the thermallyconductive basin 14 to define alower air gap 46. As stated above, theair gaps food storage containers 36.FIG. 5 also shows the use and location of a secondthermoelectric device 24, which is not visible inFIG. 4 because the second device is located directly behind the first device when theunit 10 is view from either side. - The second
thermoelectric device 24 is provided with itsown controller 32A and itsown temperature sensors 49. The tandemthermoelectric devices 24 in asingle basin 14 enable the temperature-controlledfood storage unit 10 to sink more from the right side of thebasin 14 than from the left side. Using a second Peltier device also allows more heat to be removed from thebasin 14 than would otherwise be possible with a single device. -
FIG. 5 also shows the hinged thermallyinsulated covers 48 for both trays and shows that thecovers 48 are in their closed positions. The thermally insulatedcovers 48 significantly improve the thermal efficiency of thefood storage unit 10 due to the fact that convection currents in a room where the unit is used will tend to heat the interior volume and the contents of the twotrays 36. -
FIG. 6 shows a perspective view of the bottom portion of thecabinet 12 and an optionalvariable speed blower 52 that forces room air through aduct 54 that routes room air through and around cooling fins formed as part of the hotside heat sink 28. Those of ordinary skill in the art will recognize that an increased air flow provided by thevariable speed blower 52 enables the hot side of thePeltier device 24 to dissipate more heat than would otherwise be possible. The increased heat dissipation from the hot side decreases the cold side temperature which enables the coldside heat sink 26 to absorb more heat from the thermallyconductive basin 14. - In a preferred embodiment, the fan speed and/or
Peltier device 24 power is modulated by the controller/CPU responsive to the temperature of the thermallyconductive basin 14, as measured by one or more of thetemperature sensors 49. If the temperature inside thebasin 14 falls below a predetermined value, the blower speed is reduced and/or the power to thethermoelectric device 24 is adjusted to keep the temperature of thebasin 14 within desired limits. - As stated above, a problem with prior art thermoelectric chillers is their exclusive reliance on conductive heat transfer between a thermoelectric device and a food product to be cooled. In the embodiments shown in
FIGS. 3-6 , one ormore air gaps 44 between the sides of thefood storage containers 36 and thebasin 14 permit heat energy to be transferred from the basin by radiation as well as convection because theair gaps 44 allow convection currents to exist in the cooler 10 and to transfer heat away from thefood storage tray 36. Stated another way, the embodiment shown inFIGS. 3-6 allow heat to be transferred from thefood storage basin 36 to theconductive basin 14 by radiation, and convection. In an alternate embodiment, the bottom of thetray 42 can be located adjacent to and in thermal contact with the bottom of thebasin 20 to facilitate heat transfer by conduction as well. - In a preferred embodiment, the
conductive basin 14 is sized, shaped and arranged to receive two or more industry-standardfood storage containers 36 and to provide the aforementioned one or more air gaps around the exterior of afood storage container 36. Thecabinet 12 is preferably provided with separate and independently hinged thermally insulated covers 48 for eachbasin 36. In another embodiment, thefood storage containers 36 in the basin are configured to receive a thermal insert as described in the U.S. patent application Ser. No. 12/329,795, the contents of which are incorporated herein by reference as well as a thermal insert described in U.S. patent application Ser. No. 12/478,439, the contents of which are also incorporated herein by reference. - While the preferred embodiment of the
food storage unit 10 is of a cold storage unit, those of ordinary skill in the art will recognize that thefood storage unit 10 can also be a hot food storage unit by simply reversing the orientation of the Peltier device. And while the preferred embodiment uses a Peltier device as a refrigeration unit to refrigerate thebasin 14, alternate embodiments use ice, cold water, an ice/water slurry and a conventional compressed gas refrigeration units. Alternate embodiments of a hot food storage unit steam, hot water and electrically-resistive heaters thermally coupled to thebasin 14. - The foregoing description is for purposes of illustration only. The scope of the invention is defined by the appurtenant claims.
