1 Claim. (01. 68-183) This invention relates to a washing machine and more particularly to an improved construction for washing soiled cloths or the like.
A primary object of this invention is the provision of an improved washing machine characterized by the absence of movable mechanical parts in the chamber in which the clothes are contained. v
A further important object of this invention is the provision of improved means, comprising a passage of heated air through the water contained in such a device, for agitating the clothes, water and soap or washing powder, to eilect the cleansing action of the clothes.
Still another object is the provision of such a washing machine whereby the wear and tear on clothing so washed is appreciably reduced.
Still another object is the provision of such a washing machine which is sturdy and durable in construction, reliable and eiilcient in operation, and relatively simple and inexpensive to, manu- .iacture and operate.
direction indicated by the arrows, and
Figure 3 is a sectional view taken substantially along the line 3-8 of Figure 1 as viewed in the direction indicated by the arrows.
Like reference numerals refer to like parts throughout the several viewsoi' the drawings,
Having reference now to the drawings there r is shown at I a supporting frame having a, base plate H, and adapted to support as in a peripheral groove 12 at its upper extremity, a receptacle II comprising the main body of the washer in which are adapted to be positioned clothes to be washed together with a quantity of water and appropriate washing material.
Secured to base plate in any desired manner, are a suitable source of power II which may comprise an electric motor, asin the illustrative embodiment, or any otherdesired type of motor driven by gasoline, oil, natural gas, or the like, and a blower I! of any desired conventional type. From blower I! an air duct It leads to a conical receptacle ll secured to the base or main receptacle I! by any desired means, within which is positioned an electric or other suitable heating element is, in the illustrative embodiment shown comprised of grid tubes l9 surrounded by electrical coils Ill and supplied with current from any desired source as through a wire 2i (see Figure 3). Grid it may be secured within the walls of receptacle 'l'l in any desiredmanner as by means or a series of bolts 22 engaging a circular rim 23 thereabout.
'The base of receptacle I3 is provided with a centrally disposed threaded aperture, in which is secured in fluid tight relation, as by means of a spacing washer 24, an upwardly extending vertical tube 25. Surrounding tube 28 is a sleeve '26 of larger diameter than the tube 28 provided with. a cover 21 at its upper extremity through which is passed a plunger rod 28 the interior extremity of which terminates in a cone valve 2!, and the outer extremity of which terminates: in a control knob 30.
The lower extremity of sleeve 26 terminates in P an enlarged circular flange Ii, supported as by risers or baiiles 32 on a second circular flange l3 secured-about the base of tube 25. A cover or lid 35 of any desired conventional type is provided forthe receptacle l3, and has screened air vents 34 therein,
From the foregoing the operation of the device should now be readily understandable. Clothing, together with a predetermined quantity of water and soap are flrst placed in receptacle II, and motor ll energized to drive blower'li, which, in turn, passes air through duct it in the receptacle ll where it circulates about the now energized heater ID. The heated air then passes upwardly through tube 25, the quantity passing therethrough being regulated by appropriate regulation of the valve 29, and thencedownwardly through sleeve 26 and outwardly through the space provided between the plates 3| and it into the water in receptacle l3. The turbulent action of the air bubbles passing upwardly therethrough readily reacts on the soap particles to form a rich wringer'to be driven by a motor I or thermostatic contr is to control the temperature oi the water withi receptacle II, as well as the temperature of the heating element I I. t 7
Now from the foregoing it will be seen that there is herein provided an improved washer accomplishing all the objects of this invention and others including many advantages of great practical utility and commercial importance.
As" many embodiments may be made of this inventive concept. and as many modifications may i bemade in the embodiment hereinbeiore shown and described. it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
In combination with a washing machine including a receptacle for clothes and water, a vented closure cover therefor. a source of power. an air blower operable thereby having a discharge air duct terminating in a conical receptacle underlying the major portion oi the bottom oi said receptacle and secured thereto, a heater for the air disposed in said conical receptacle positioned immediately below said receptacle bottom and underlying the major portion thereof,
means for directing said heated air into said receptacle adjacent its base including a tube exdownwardly about and spaced from said tube'and 1 communicating at its lower end with a pair of outwardly extending spaced baflle plates, a plurality oi radially extending vertical bale plates disposed between said first mentioned bale plates. and means for controlling the quantity 01 air admitted to said receptacle including a valve seat in the upper end of said tube and a valve thereior adjustable exteriorly 0! said sleeve. iii
