'1 Claims. (Cl. 68-37) The present invention has for an object to provide an improved washing machine. The invention has been developed in connection with the design of a washing machine intended more especially for family use and operating on the principle of causing a surging of the washing water together with an agitation of the water by passing air therethrough intermittently.
The nature and objects of the invention will be better understood from a description of a particular embodiment thereof for the purpose of which description reference should be had to the accompanying drawings forming a part hereof and in which- Figure 1 is a central sectional view of a washing machine constructed in accordance with the invention,
Fig. 2 is a sectional view taken on the line II-II of Fig. 1, and
Fig. 3 is a top plan view of the same.
The machine shown for the purpose of illustrating the invention comprises a sheet metal tub 5 with a clothes container 6 suspended centrally therein on three spaced brackets 7, said clothes container having an imperforate cylindrical side wall and a perforate bottom 8 within which and spaced therefrom is a false bottom consisting of a perforated plate 9.
The tub is provided with a trussed sheet metal cover 10 in which is mounted an operating motor 11 on the shaft of which is carried a fan 12 operative to create a suction in the clothes container and thereby cause a surging of the water between the clothes container and the portion of the tub exterior thereto.
As shown, the tub is reinforced around its upper outer edge by a metal band 15 and it is provided with a rubber packing ring 16 formed around the reinforced upper edge. On this rub- 40 her packing ring the cover 10 rests to provide a substantially air-tight joint. The cover shown as of sheet metal comprises a main cup-shaped or crowned disc which is reinforced by a substantially flat disc 17 extending across the cover and secured thereto, as by spot welding, as indicated at 18, to form a truss-like structure. The rigidity of the cover is further increased by a cupped disc 19 spot welded to the outer cover member, as 50 indicated at 20, and to the trussing disc 17, as
indicated at 21. The shaft 23 of the motor 11 extends through a spring plate 37, which is normally curved upward at the ends through which the hold down screws pass. These screws cause pressure to be exerted on the felt packing washer 24 to prevent moisture from passing upward into the motor.
The fan 12 carried by the motor shaft 23 is designed to create suction in the clothes container and to deliver the air withdrawn therefrom to the tub outside of the clothes container. A cover 25 for the clothes container is carried by the tub cover in spaced relation thereto to provide a fan chamber for the fan 12. It is suitably crowned and secured to spacing blocks 27 and at its outer edge carries a flexible rubber packing ring 28 engaging the upper edge of the clothes container and forming a substantially air-tight connection. The disc 25 is centrally apertured at 29 and the aperture closed by a screen 30. In order to prevent the closing of the opening 29 in the event of ballooningof the clothes a guard 31 is provided, said guard being of cup-shape with a number of openings 32 in its bottom face and a number of openings 33 around its periphery in the vertical cylindrical portion thereof as clearly shown in the drawings.
For convenience in handling the motor is provided with a suitable handle 35 and the tub is provided with a pair of oppositely positioned handles 36.
In operation the clothes being placed in the central clothes container, the tub is filled with water up to the level indicated by the water line 37 in Fig. l and the motor is then started. The fan 12 creates a suflicient suction to cause the water to surge from the tub 5 into the clothes container 6 until the Water level in the tub falls to below the bottom of the clothes container whereupon, due to the continuing suction, air is drawn from the tub in through the bottom of the clothes container to further agitate the water and clothes within the container. The inrush of air as the water seal is thus broken breaks or reduces the vacuum within the clothes container and permits the water to surge" back through the bottom of the container into the exterior tub, but after a few seconds the suction withinthe clothes container is again built up and the inrush of water and then air is repeated. During the continued operation of the water this action. is repeated again and again providing the desired surging of the water and intermittent agitation of the water by an inrush of air.
The motor is ordinarily but not necessarily run continuously at a uniform speed, it being ordinarily unnecessary to provide an intermittent action of the motor to effect the surging for the reason that the breaking of the vacuum upon the inrush of air sufficiently permits the outward surge of the water.
The foregoing particular description isillustrative merely and is not intended as defining the limits of the invention.
