(ci. ss-1st) 1 Claim. l This invention relates to washing and drying machines and more particularly to machines of tion and in the claims wherein parts will the type in which warm or hot air is forced l through saponified water to create suds which percolate through the clothes within the machine and flush and clean them.

-One object oi this invention is the provision therein, of means for discharging the suds from the machine as they become soiled during the process of cleaning the clothes.

Another object of this invention is the provision therein of a machine of the type speciiled wherein there are no moving mechanisms within the tub or container for soiled clothes.

A further object of this invention is ,the provision therein of means whereby air under pressure, is heated to various temperatures and is forced through the water in ythe machine and wherein means is provided to control the degree of temperature of the air.` I

A further object of this invention is the'proision therein of a machine comprising simple parts within the tub which are readily removable to permit easy cleaning of the tub and parts therein.

Another object oi' this invention is the inclusion therein of a heating unit with-fn an air chamber, which is in turn connected to a perforated distributor grill or coil in the tub and a blower unit also connected to the air chamber to for^e heated air through the saponiiied water in the tub.

A further object of this invention is the provision therein for utilizing the machine for washing and drying dishes and the like.

A further object of ths invention is its adaptability for including a standard remote control 'with a standard sink and tub unit to draw off the water from the tub without displacing the clothes therein.

A further object of this invention is the provision therein of a blower unit and` air heater which is adaptable to various household utilities.

A still further object of this invention is thc provision of a device in which the constituent elements are so arranged structurally and functionally as to assure improved results with materials and members which may be manufactured at reasonable oost, may be easily assembled and which will be eilicient in operation with minimum wear to the parts.

The invention possesses other objects and features of advantage, some of which, with the foregoing will be set forth in the following descripidentified by speciilc names for convenience, but they are intended to be as generic in their application to similar parts as the art will permit. In the accompanying drawings there has been illustrated the best embodiment of the invention known to me, but such embodiment is to be regarded as typical only of many possible embodiments, and the invention is not to be limited thereto.

The novel features considered characteristic of my invention are set forth with particularity in the appended claim. The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawings, in which:

Figure 1 is a sectional elevation of the device set up for use.

Figure 2 is a plan view of the device with the l cover removed.

Figure 3 is a top view of the cover of the device which is provided with a soap suds discharging spout as will be hereinafter described.

Figure 4 is an end elevational view of the cover.

Figure 5 is a sectional view of same taken along line 5-5 of Figure 3, looking in the direction indcated by the arrows.

Figure 6 is an elevational view, partly in section, of the device applied to a combination kitchen sink and washtub.

Figure 7 is an enlarged longitudinal section of a heating unit used in the device.

Figure 8 is an enlarged sectional view of 'same taken along the line 8-8 of Figure '7.

Figure 9 is an isometric view of a part of the heater unit.

Referring in detail to the parts, i l designates a vessel suitably mounted upon a base plate i2 and provided with a draw oil valve i3. A tube or` pipe'filfhaving perforations I5, is formed in a coil I8 (Figure 2), and rests upon the bottom |'1 of the vessel. ii. A tube i8, which may be ilexible, connects this said coil i6 with an air chamber and heating. unit I! which is in turn, connected by means of a pipe 20, with a blower 2 I actuated by means of a motor 22. A cover and sud discharging member 23, forme with a. supporting flange 24, is adapted to engage over the open top end of the vessel Ii, and is provided with a slot 25 to permit the passage of said pipe i8. The said cover is further provided with a discharge spout extending from one end thereof and adapted to direct the iiow of suda. while the machine is in operation. from the machine. An inlet 21 and cap 2l is provided in said cover 2l and an observation glass 29 is held thereon to provide a means of observing the action in the vessel while the clothes therein are being cleansed.

A basket of wire mesh Il may be provided to hold the clothes, though the use of this basket is not essential to the proper operation of the washer. When the basket l is not used a wire mesh tray 3 I (Figure 6) may be employed. It will be optional with the user to employ either the basket 30 or tray 3l or omit either when using the device.

The air chamber Il (see Figures 7, 8 and 9) comprises a cylindrical casing 32 of metal, preferably copper, having a tapered or conical shaped end 33 and connecting with the aforesaid tube Il which leads to and connects with the coil IB in the vessel Il. The opposite end 34 of the air chamber I9 connects with the aforesaid blower unit 2|. The said air chamber also comprises a heating unit, is lined by a coating of mica 35 and carries, spaced at intervals therein,

baille elements

36 and 31. The said bames 38 and 3l are alternately spaced, at intervals, on opposite sides, inside the said cylindrical casing (Fig. 7) and are held in place by

tie rods

33 and 33 which engage in slots 48 formed upon the said baii'les 36 and 31. Nuts 4I and washers 42 are employed to tighten upon the said baiiies to hold same in place. The

tie rods

33 and 39 are secured, at their ends to ring

members

43 and 44 at opposite ends of the said cylinder 32. An insulating Jacket 45 of asbestos or other suitable material is provided to encircle the cylinder 32. Electrical heating elements 48 are carried in

bafiles

36 and 31 and are mounted upon porcelain tubes or knobs 41 which engage in slots 43 upon the periphery of said baiiles.

A control switch and rheostat 43 (Figure l) is provided upon the heating unit and air chamber and anords a means for controlling the electrical energy to the heating elements 48. The electrical connections throughout are standard and are not shown.

To prepare the device for use, the coil I3 is placed upon the bottom Il, in the vessel Il, is connected by the pipe I9 to the air chamber and heating unit I9 and by the pipe 20 to the blower 2l. Clothes to be washed are 'immersed in sa poniiled water within the vessel II and the cover and suds discharging unit set in place. The electric current to the motor and heating unit is turned on to heat and drive the air through the perforations in the coil and up through the soap water. The pressure of the air as it is forced through the outlets in the coil will agitate the clothes and cause a uniform distribution of heated air and soap water through the clothes fabric and insure thorough cleaning thereof.

By using any suitable rack or basket ior holding same within the vessel, dishes of al1 types may be cleansed and dried. Further, the air heater and blower units may be utilized in connection with the various utility units in the household.

When the clothes in the vessel have been thoroughly cleansed and the water in the vessel drawn oi! through the tap or valve I3, the heated air. under pressure, may be blown through the clothes to dry them,

A standard remote control valve (not shown) may be disposed in the draw oil or drain pipe between the said draw off i3 and the house drain connection so that the water in the tub may`be drained and the tub reillled with fresh water without removing the clothes or dishes therefrom.

I claim:

The combination in a washing and drying machine comprising a clothes and saponii'led water containing vessel, an air distributing coil in the said vessel and an air compresser having tubular connection with the said air distributing coil. of a heating unit disposed in said tubular connection and comprising a cylindrical metal casing having tapered conically shaped ends, a lining of mica within the cylindrical casing, baille elements being alternately spaced on opposite sides within the cylindrical casing, tie rods extending longitudinally through the said baffles to hold same in place, electrical heating elements mounted in said bafiles upon insulating knobs, an insulating jacket around the outside of the cylindrical cylinder, conductor means to supply electrical current to the said electrical resistance elements and a controlling switch to regulate the ow oi' current through the said electrical heating elements.
