1 Claim.

The present invention relates to washing machines.

The primary object of this invention is to provide a washing machine wherein the washing water is agitated and the suds caused to circulate by employing a current of air.

Another object of the invention is to provide a device of the character referred to without using moving parts in the tub, thus obviating damage to the articles being washed.

A further object of the invention is to provide a device of the character referred to of simpler and more compact construction than prior devices.

A further object of the invention is to provide a device to separate dirt out of the major portion of the washing water and accumulate such dirt in the bottom of the washer, thus making for faster washing and cleaner clothes.

With the foregoing and other objects and advantages in view, the invention consists of the novel constructions and arrangement of parts hereinafter described and claimed.

In the accompanying drawings illustrating the invention:

Figure l i a top plan view with the cover broken away partially to expose the interior of the washing machine.

Figure 2 is a vertical longitudinal section thereof.

Figure 3 is a bottom plan view of the removable plate which seats on the bottom of the tub.

Like numerals, as used in the description and drawings, designate the same structural parts.

In refers to the tub of the washing machine. Thi is preferably cylindrical with a removable top H to effect a sealing closure and both of i said elements may be constructed of metal or other suitable material.

The tub is mounted on legs 12, preferably on casters, and provided with a concave annular false bottom l3, perforated and surrounding the raised fiat central area of the tub bottom 9 which has a centered boss which in turn has a central round aperture I4.

Surrounding this aperture is a threaded boss l5 which depends on the under side of the bottom for attachment of an elbow pipe I6 connected to the hot air conduit ll.

A glutter l8 forming part of the bottom 9 surrounds the under side of the tub bottom I3 and is provided with a drain cock l9. Perforations gutter and permit the water to be drained off after the washing operation.

Seated on the tub bottom is an horizontally disposed, circular baffle plate 2| having a convex or dome-shaped top and convolute channels 22 on the under side from center to rim. A vertically channeled plug 2'3 depends from said plate and fits in the aperture of the tub bottom, thus allowing the hot air from the heater to circulate between plate and tub bottom.

A switch 24 on the heater 25 provides for cur-- rent from a source of supply and a suction fan 26 associated with said heater serves to draw a current of air into the conduit I! to circulate in the wash water after the heater is shut off. A small motor 21 operates the suction fan.

By the aforesaid construction, a large part of the dirt content of the washing water is segregated and thrown in the direction of the perimeter of the tub bottom, where it settles in the false bottom and through perforations, escapes to the drain gutter I8 and is drawn off by the drain cock I9.

In operation the top H i removed from the tub l0 and the tub is filled partially by hand with hot water, whereupon soap is added to the water. Into this water is introduced the clothes to be washed after which the top H is placed on the tub ID. The heater switch 24 is closed. to cut in the heater and then the motor is cut in, resulting in heated air being sucked into pipe I1 by means of the suction fan 26. This current of air enters the tub at the aperture l4 and is diverted radially by the baffle 2|, thus circulating freely through the hot water and suds in the tub. This current of air causes air bubbles to form and thereby not only facilitates the circulation, but causes such bubbles to pass through the fabric of the articles in the tub. This assists the suds to loosen and dissolve the dirt. The water can be kept at an even temperature while washing and rinsing. After the garments are thoroughly rinsed, the tub water is drained off and the garments dried in the tub by turning on the heater alone.

As different embodiments may be made of this inventive concept, and modifications may be made in the embodiment hereinbefore shown and described, it will be understood that the matter herein is to be interpreted as illustrative merely, and not in a limiting sense.

What I claim is:

20 in the false bottom communicate with said M I a washing machine comprising a tub, a

.3 bottom having a central inlet port, a bafile plate removably seated upon the intermediate portion of the bottom over the inlet port and having outwardly extending air channels in the underside communicating with said inlet port, and means for supplying heated air to the latter port, the features which include a deep peripheral gutter portion in the bottom, a central fiat raised area upon said'bottom surrounded by said peripheral gutter portion supporting the baflle plate, a drain cock connected to the gutter portion, a domeshaped convex top upon said bafile plate, having the air channels in the underside of said bafile plate convolute in form, and an annular concave and perforate false bottom disposed over the peripheral gutter portion about the central, flat raised area of said bottom with the deeper poriii tion of said false bottom below the level of said central area.
