2 Claims.
This invention relates to domestic appliances.
An object of this invention is to provide an improved washing machine for washing clothes in which the clothes are agitated by the forcing of liquid into the clothes and a continuous supply of forcing liquid to the pumping device is insured.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the present invention is clearly shown.
In the drawings:
Fig. 1 is a vertical cross-section of an apparatus embodying my invention; and
Fig. 2 is a horizontal section-plan view taken along the line 22 of Fig. 1.
A washing machine embodying my invention, in general, comprises a tub I provided with a false bottom supported above a pump l2, which is driven by a motor l3. The pump l2 has an upwardly directed intake opening l4 and a plurality of radially directed discharge arm l5 extending to the periphery of the tub where they are bent inwardly at I6 to discharge the liquid radially inwardly through the nozzles H. The false bottom turned upwardly at this point, as indicated at I8, is provided with openings l9 through which the nozzles discharge. The false bottom may be continued by a flared apron 20 to the edge of the tub. A ba-file 2|, preferably cone-shaped, is supported above the pump l2.
Liquid and clothes are placed in the tub, and the pump is driven by the motor l3 in such a manner that the liquid enter at l4 and is discharged in confined paths through the arms l5, bends l6 and nozzle radially inward through the openings IS. The main body of liquid and the clothes are caused to be agitated and are given a toroidal action, as indicated by the arrows 22. A continuous supply of liquid for the opening I4 is insured by the flow of liquid through the perforations 23 of the false bottom The false bottom Ii supports the clothes away from the opening M. The inward discharge of Washing fluid at I9 prevents the clothes from clogging the openings 23 by the forceful action of the discharge at this point.
The motor-pump structure is so arranged that it is easily assembled with the tub. For this purpose, a motor-frame structure is provided which includes a securing ring 36 located below and around the tub opening 3|. The motorframe structure also includes the motor I3 supported by the downwardly directed arms 32 carried by the ring 30. The arms 32 carry a lower ring 32a on which the motor I3 is supportedby means of the rubber supports 3212. A pumpframe structure is provided which includes a securing ring 33 secured above and around the opening 3|. The rings and 33 are secured to gether by means of bolts 34. Preferably gaskets 35 and 36 are interposed between the respective rings 30 and 33 and the tub bottom.
The pum structure, in addition to the ring 33 includes an inlet plate 31 resting on the ring 33. A rotary impeller 38 i also provided which is carried by a shaft 39 journalled in a bearingextension 40 depending and secured to the ring 33 and passing through the opening 3| The pump shaft 39 is secured to the motor shaft 4| by means of a flexible sleeve 42, made of rubber or the like, into which the shafts 39 and 4| may beinserted during assembly. The impeller 38 rides on a bearing plate 42 supported above a packing gland 43 through which the shaft 39 passes. The hearing extension 40 is provided with a porous bearing sleeve 44 and lubricant packing 45 which can be provided with lubricant through the oiling cup 46. The impeller 38 is held from axial displacement by means of the ring 41 secured to the shaft 39.
The arms l5 are secured to the ring 33 preferably so that they are a unitary assembly with the ring 33 and can be connected to the tub at the same time that the rings 30 and 33 and the intake plate 3l' are secured together by the bolts 34. The false bottom preferably is removable and rests in the tub by any suitable form of support, such as the brackets resting on arms [5 or the like. Preferably the cone 2| is also removable and is secured to the false bottom I I.
From the foregoing description it is evident that the motor pump structure can be readily assembled on the tub after parts of the structure have been sub-assembled. Thus the motorframe structure can be sub-assembled, the pump rin 33, together with the arms l5 can be sub assembled, and thereafter these parts can be secured together in the tub as hereinbefore indicated. This provides a very efficient washing device which is economical to produce and operate.
While the form of embodiment of the invention as herein disclosed. constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.
What is claimed is as follows:
1. A washin machine comprising a tub having an imperforate bottom, a perforate false bottom in said tub above said imperforate bottom, a
central upstanding baflie above said false bottom, a centrally dispomd pump below said false bottom having intake means between said bottoms; and radial discharge passageways from said pump extending to the periphery of said tub and.
bend with discharge openings therein, a central upstanding banie above said false bottom, a centrally disposed pump below said false bottom having intake means between said bottoms, and radial discharge passageways from said pump extending to the periphery of said tub and discharging radially inwardly into said discharge openings in said false bottom to discharge forcible streams immediately above said false bottom to create toroidal circulation of liquid above said false bottom and to sweep articles be- ,ing washed away from said false bottom.
