Application April 8, 1953, Serial No. 347,434

2 Claims. (CI. 68-20) This invention relates to laundry machinery and more particularly to domestic laundering machines of the automatic cycle type wherein laundry is Washed, rinsed and dried in the same compartment.

One of the objects of this invention is to provide a machine which is capable of carrying out the sequence of washing, rinsing and drying the laundry in a wholly automatic manner, and doing so with a minimum of mechanisms.

With the machine of the present invention, the operator may place the laundry, sprinkled with soap, in the tub, connect the electric circuit and cock the batch water supply valve; then leave the machine for an indicated period such as overnight. On return the laundry will be found in the same compartment, washed and dried.

Another advantage lies in the elimination of outlet valves in the functioning of the machine.

Yet another advantage lies in the unifiow passage of rinsing water mixed with agitating air which starts with the rich soap liquor mixture in the clothing and drives through to a wholly rinsed laundry, so tending to sweep disengaged dirt, and soapy solutions out of the laundry in a progressive manner.

Other objects and advantages will be noted in the course of the detailed description on an embodiment of the invention which follows. Although only one form of the machine is described and illustrated, it is to be expressly understood that this is not to be construed as defining the scope of the invention, which scope is defined in the appended claims.

In reference to the annexed drawing, it will be noted that this is a schematic presentation of the invention which fairly exhibits the simple and effective character of the machine.

1 is a whole tub of a washing machine. 2 is an internal subdit'iding Wall extending from the top to near the bottom of the tub and forming with a false perforated bottom 3 a semiseparate chamber 22. 4 is a drain system having, 41 a large overflow and 42 which is smaller than 41. There is a singed top 5 equipped with an air vent 7. Connected to chamber 22 is an air pump 6. 8 is a fresh water inlet through which 9 a water batch valve feeds a predetermined supply of water greater in amount than the capacity of drain 42 and less than the capacity of

drains

41 and 42 combined. is an electric resistance unit mounted under the tub to supply heat to water and air processes. 45 is the maximum level of still Water in the tub.

In operation laundry to be cleaned is sprinkled with soap and placed through door 5 on to false perforated bottom 3. Electric current is connected to motor driving air pump 6 and the heat unit 10 and the water batch valve 9 is cocked to deliver a desired amount of water, which flows, with the air through chamber 22 and the perforations in 3 on to the laundry. Water and soap mix in the rising water level as water delivery of 8 and 9 exceed outlet flow of 42. This initially forms a strong liquor of soap and Water, very desirable in dislodging dirt. The laundry and water mix is agitated to further this process by the movement of the air through it. The water finally overflows through 41. and rinsing of laundry takes place asthe tub is filled plurality of times by valve 9.

After delivery of a predetermined amount of Wash and rinse water has been effected by valve 9 it shuts off. The drying cycle is initiated when lower drain outlet 42 finally empties the tub of water. At this point the heat source it) warms the air passing through the chamber 22 in lieuof water, and the drying cycle begins on the laundry on 3 as heated air reaches the laundry through the perforations. Air pump 6 supplies air and heater unit ill supplies heat until the current supply is stopped after completion of the drying cycle. Vent 7 provides an outlet for the air introduced and may be connected to a flue or outlet if desired.

It will be noted that air pump 6 has its outlet or pressure side connected to chamber 22 to force air through. Instead it may, with facility be connected to vent 7 on its suction side to effect this purpose. This aspect of invention therefor really comprises an air pump means to propel the air through chamber 22 and false bottom perforations and into the main body of the tub.

A factor in the washing and rinsing phase is the combined flow of water and air in a common direction resulting from placement of inlet 8 in chamber 22. unifiow action increases the apparent volume of water besides agitating it and further facilitates the removal of dirt and soapy mixtures from the laundry.

Having thus described my invention, what l claim is: l. A laundering machine adapted to automatically carry out a cycle of washing, rinsing and drying laundry in the same compartment, the machine comprising a tubhaving an internal subdividing wall extending from above the waterline to a point near its bottom and dividing the volume into a larger and smaller compartment, 21 false perforated bottom in the larger com artment forming a. substantially continuous wall with the above vertical wall to complete the division of the tub into a large chamber" partly and a smaller chamber laying partly beside and below said larger chamber; a water system connected to said tub comprising a plurality of drains one of which shall be mounted above the other, the upper of w shall have a larger capacity, a water supply cons having an inlet capacity larger than the lower drain 1 less than the combined capacity of the lower .i other drains, said inlet water connection having a metered volume water valve feeding said inlet, a cover for thelarger laundry chamber and vent thereto and air pump means to cause movement of air from the sm..ller subdivision through the false bottom and into the main chamber and a heat source mounted below the true bottom: of said tub.

2. In a machine of the class described a tub having an internal subdividing wall extending from above the waterline to a point near its bottom and dividing the Volume into a larger and smaller compartment, a false perforated bottom in the larger compartment forming a substantially continuous wall with the above vertical wall to complete division of the tub into a large chamber and a smaller This" 3 4 a plurality of drains one of which shall be mounted above References Cited in the file of this patent the other, the upper of which shall have a larger capacity, UNn-ED STATES PATENTS a water supply system connection having an lnlet capacity larger than the lower drain and less than the combined 1,054,990 SchWPerer 41 1913 capacity of the lower drain and other drains, said inlet 5 212031029 Parmdge June 41 9 Water connection having a metered volume water valve 2,434,476 Wales 1945 feeding said inlet; a cover for larger laundry chamber and 2,555,268 Chamber hn May 1951 vent thereto and air pump means to cause movement of 2,607,209 constantme 191 1952 air from the smaller subdivision into the main chamber.
