This invention relates to dish washing a single rigid 'nonrotary part or frame 11 machines and aims topr'ovide an efiicient which provides the stationary part of the dish washing machine adapted to household (lISh washing mechanism, the stationary part use.

The the hub and arms. The hub 22 is retained present application is directed to the comwin the discharge neck by a bushing 25 whosebining of such units with sinks. lower edge is engaged by an external flange The invention may best be understood 26 at the lower end of the hub. The bushing from a detailed description of the specific 25 is removably held in the neck 16 by embodiments of it which are illustrated in screw 28 which passes through the neck and the accompanying drawings, in which enters the groove 27 in the bushing.

The sink Fig. 2 is an elevation partly in section 30 may be of the usual size and shape except showing a dish washing unit mounted inthat it is provided at the center of its bottom the bottom of a sink; and with a circular well 31 at the bottom of Fig. 3 is a plan view of the arrangement which is an opening 32. The unit 10 is -mounted in this opening 32 b securing its washing mechanism above the bottom of flange 17 to the bottom of t e well about the sink removed. the periphery of the opening so that the A dish washing unit 10 of the type debottom 14 of the pump body 12 forms a the opening 32. The depth of pending application is shown in Fig. 1. the well 31 is such that while the entire pump This unit combines dish washing mechanism casing 12 is below the bottom 33 of the and actuating mechanism therefor, and has sink 30, the arms 23 are above the bottom ered by.a screen 39 which is at the level of the bottom 33 of the sink. The drain opening in the bottom 14 of the pump body 12 of the unit frame may be connected to the drain pipe of the sink through a valve 40. It is not necessary to connect this opening with a source of hot water as the well 31 may be filled with hot water from the hot water faucet 41 of the sink. This is done before the cover 37 is placed in position.

In using the dish washing unit the well 31 is first filled with hot water from the faucet 41 to a depth sufiicient to cover the inlet openings 15 of the pump body of the unit. A detergent may be added to this water. The dishes to be Washed are placed in the rack 35 and the cover 37 is placed over the rack. The motor is then operated. rotating the shaft 19. This rot-ates the impeller 20, causing it to draw water into the impeller chamber through the inlets 15 and to force this water through the hub 22 into the arms 23 and out through the discharge nozzles 24. As the arms are rotated b the reaction of the water discharged throug the inclined nozzles, the water is thrown forcibly upward against all the dishes or other articles in the rack 35, thoroughly cleansing them in a very short time. During this operation, the solid matter removed from the dishes is caught on the screen 39 and is thus prevented from entering the pump body. On the completion of the washing, the water in the well 31 is withdrawn by opening the valve 40. The cover 37 is then removed and the well 31 is filled with clean water from the faucet 41. The cover 37 is replaced and the motor is again placed in operation to rinse the dishes and remove all soapy water from them.

When it is desired to use the sink 3O independently of the dish washing unit, the cover 37 and the rack 35 are removed from the sink. The screen 39 may then be removed so that the screw 28 may be reached and loosened, permitting the withdrawal of the bushing 25 from the discharge neck 16 so that the arms 23, hub 22 and bushing 25 may be lifted out.

The screen 39 is then replaced and a lug or cap 42 placed in the discharge nec 16 (Fig. 3). When this has been done no portion of the washing mechanism remains within the sink 30 so that the sink may be used in the ordinary manner.

What is claimed is:

1. The combination of a sink having a substantially flat bottom and a well in its bot tom, an upwardly directed conduit fixed in said Well and terminating below the level of the bottom of the sink, means for forcing liquid upwardly through said conduit, and means for distributing said liquid in the sink located above the bottom of the sink and dctachably secured to said conduit.

2. The combination of a sink having a well in its bottom and an opening at the bottom of said well, of a dish washing unit comprising a rigid frame including a pump casing located wholly below the bottom of the sink and having an intake opening communicating with said well, and an upwardly directed discharge neck terminating substantially at the level of the bottom of said sink, and a motor casing below the pump casing, and formed to provide a closure for the opening in the bottom of the well; a motor in said motor casing having a shaft projecting into said pump casing; an impeller mounted upon said shaft in said pump casing; a rotar hollow hub detachably mounted in said neck; and hollow spray arms extending radially from said hub above the bottom of said sink and provided with upwardly directed inclined discharge orifices.

3. In a dish washing machine, the combination of a support for articles to be washed,

a casing enclosing the support and having opposite side walls merging gradually into its top to provide a deflecting surface arching over the support, and a distributor located wholly under the support, rotary about a vertical axis midway between said side walls, and having at its bottom an axial intake opening through which liquid is forced under pressure, and on its top at opposite sides of its axis discharge orifices directing liquid issuing therefrom up through the central and outer portions of the support and obliquely against opposite side portions of the deflecting surface at the same time.

In testimony whereof we have hereunto set our hands.
