2 Claims.
This inventionrelates to dish washers andparticularly to a device of this general character which may be manipulated to wash or. clean dishesand other articles, the device terminating in a distributor head, fountain brush or the like to which clear water or a predetermined mixture of water and foam producing detergent or equivalent substance may be supplied under pressure.
An'object of the present invention is to provide a manually operable dish washing device or the like of the foregoing kind having a reservoir or chamber containing a supply of liquid detergent communicating with a Venturi passage interposed in a water or other liquid pressure supply conduit, whereby the detergent may be drawn as desired into the supply conduit by suction or negative pressure in accordance with the settin of a valve conveniently arranged for manual operation.
A further object of the invention is to provide a dish washing device having a flexible conduit adapted to be connected to a source of water under pressure and terminating in adistributor head, brush or other cleaning member, the device including a reservoir containing liquidfoarn pro ducing detergent and a valve controlled duct or conduit leading from the reservoir to a Venturi whereby either a predetermined mixture of water and detergent or clear water may be discharged from the device as desired.
Another object of the invention is to provide a dish washing device of the foregoing kind in which the flexible conduit may be detachably connected at one end to the spout of a hot and cold water mixing unit associated with a kitchen sink and the Venturi together with the detergent reservoir communicating therewith is carried by a handle disposed in the length of said conduit.
Still another object of the invention is to provide a-fiexible conduit through which water under pressure isadapted to be supplied to a washing or cleaning element at the discharge end thereof, and Venturi means for mixing a foam producing detergent or similar substance with said water to produce'a foam or suds effect at said discharge end, the amount of such mixture of water and detergent being conveniently controlled by a valve in the handle of the device locatedproximate to the Venturi.
Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.
Fig. 1 is a perspective view of a conventional kitchen sink and a hot and cold water mixing valve unit to which is connected a dish washing device constructed in accordance with one embodiment of the present invention.
Fig. 2 is aplan view of. a portion of the dish washing device shown in Fig. 1.
Fig. 3 is a side elevation, partly in section, of the structure shown in. Fig. 2.
Fig. 4-is an enlarged fragmentary section taken substantially through lines 4.-4 of Fig. 2 looking in the direction of the arrows.
Fig. 5 is a fragmentary view illustrating a fountain brush attached tothe discharge end of the device.
Before explaining in detail the present invention itis to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it is to-be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
In the drawings there is illustrated, by way of example, one embodiment of the invention as applied to a dish washing device adapted to be used for washing or cleaning dishes or the like in any conventional sink, such as that illustrated at l0 in Fig. 1 Associated with the sink is a hot and cold water mixing unit H which may be mounted on the splashback Illa of the sink, as shown, or in any other well-known manner at the back of the sink, this unit having the usual swinging delivery spout I2 and hot and: cold water supply valves controlled by handles I3 and IA.
The present washing device comprises a cylindrical reservoir l5 which in the present instance forms a handle or hand grip which may be grasped for manipulating the device. Fixed to the front and rear ends of the reservoir cylinder [5 are closure caps It and Il, respectively,.these caps being securedin such manner to the cylinder as to seal the chamber lEa within the cylinder against leakage of liquid therefrom. Threaded into a tapped hole in the top of the reservoir cylinder l5, such as at the rear end thereof, is a filler cap l3 which may be removed in order to introduce into the chamber 55a a supply of liquid foam producing detergent. Any suitable liquid detergent, well known on the market, may. be utilized or the liquid detergent may be prepared by dissolving a small quantity of detergent powder inwater and then introducing the same into the reservoir cylinder [5.
Extending into the cylinder l5 and secured within a hole in the end cap ii is an inlet tube Iii, the rear end l9a of the tube projecting through the cap or closure ll and being threaded for the attachment thereto of the enlarged end 20a of a coupling member or nipple 20 which receives the outer end of a flexibletube or rubber hose 2 l. The tube or hose 2| may be of any. desired length and has itsinner end M a constructed so as to permit its ready attachment to the spout l2 by forcing it over the discharge end of the spout, as shown in Fig. 1.
The inner end l9b of the inlet tube I9 is threaded for the attachment thereto of a tubular member 22 which is herein termed, for convenience, a
Venturi coupling, this coupling having a passage 23 communicating with the passage through the tube l9 and being provided with a tapped counterbore into which the end of the tube I9 is threaded. The cylindrical passage 23 in the Venturi coupling 22 communicates with a Venturi passage 24 formed within the coupling and this Venturi passage flares out for communication with a central passage 25a in the outlet or distributor tube 25 having press fit within a hole in the coupling 22 and extending through a hole in the end cap 16, being attached to the latter by means of a coupling 26. Suitable gaskets are interposed between the couplings 2B and 23 and the end caps H and IS in order to prevent leakage of liquid from the reservoir cylinder IS.
The distributor tube 25 forms with the reservoir cylinder l rigid unit which may be ma- .distributing head. The base 21 has an annular threaded flange 21a to which is detachably connected a distributor disk or head 28 which is foraminous or perforated in order to provide a multiplicity of small discharge orifices or holes 2801. having a total area as great as the cross sectional area, of the passage a, thus permitting an unrestricted flow of liquid under pressure through the distributor head. In using a distributor head 21, 28 of the general type illustrated in Fig. 3 either a spray of, pure water or a foam producing mixture of water and detergent may be discharged from the head. However, it will be understood that the perforated discharge member 28 may be replaced, as illustrated in Fig. 5. by means of a fountain brush 29 or any other suitable cleaning or scrubbing device.
The Venturi coupling 22 is provided at the locality of the Venturi 24 with a hole 30 extending preferably at right angles to the longitudinal axis of the coupling. This hole is tapped to receive the threaded reduced end 31a of a valve member 3! having a small passage or duct 32 opening into the Venturi passage 24. In the present instance the upper portion of the valve member 3!, which lies within the chamber l5a, is drilled to provide a longitudinal passage or duct 33 communicating with the duct 32 and also with the liquid within the chamber [5a. The upper end of the duct 32 at its juncture with the duct 33 is machined to provide a tapered valve seat engageable by a tapered or conical valve 34 carried by a valve stem 35 slidable vertically within a hole in the valve member 3!. The valve stem 35 has a sliding fit in a hole in a plug 36 which has a reduced threaded end screwed into a tapped hole in the cylinder l5.
The upper projecting end of the valve stem 35 projects within the bifurcated end 38a of a lever 38 and is pivoted thereto at 31. The lever extends between the spaced upright sides of a U-shaped bracket 39 and is pivoted thereto at at intermediate the ends of the lever. The bracket 39 has a base 39a secured by means of a bolt Idl to the cylinder I5. This base of the bracket is overlapped by the head 36a of the plug 36 which assists in holding the same rigidly in place. The rear end of the lever 38 terminates in a finger piece 381) which is engaged at its underside by the outer end of a leaf spring 42, the inner end of this spring being confined between the base 39a of the bracket 39 and the cylinder l5 and clamped in place by means of the bolt 4|.
The spring 42 engaging the rear end of the lever 39 functions to hold the lever normally in the position shown in Fig. 4, thereby forcing or urging the valve stem 35 downwardly with the valve 34 fully seated within the valve member 3| and, hence, closing off communication between the chamber Ifia and the passage or duct 32 in the valve member. Thus, when the valve is seated, as shown in Fig. 4, water under pressure flowing through the Venturi passage 24 from the inlet tube l9 to the outlet tube 25 will not withdraw or entrain therewith any liquid detergent from the chamber Ilia. Hence, under these conditions clear water under pressure will be discharged from the distributor head 28 or fountain brush 23. When it is desired to entrain liquid detergent with the Water flowing through the Venturi coupling 22 the finger piece 38b is pressed down by the thumb thereby raising the valve 34 from its seat and opening communication between the duct 32 and the duct 33 leading into the chamber lfia. Under these conditions water flowing under pressure through the Venturi passage 24 will by suction or the creation of negative pressure within the Venturi passage withdraw liquid detergent from the chamber lEa through the ducts 33 and 32. This liquid detergent will be entrained with the water flowing through the Venturi passage and a foamy discharge will be produced at the discharge end of the nozzle.
I prefer to provide means not only for air venting the reservoir chamber l5a but also for permitting air to be drawn along with the detergent into the stream flowing through the nozzle tube 25. As a consequence, the foamy discharge will be aerated and increased in volume thus reducing the amount of detergent used without impairing the cleaning action. The foregoing is accomplished, by way of example, by machining a small air bleed groove or channel 45 on the outside of the valve stem, the lower end of the groove terminating at the valve 34 and the upper end being open to the atmosphere. When the valve is seated by the action of spring 42 no air will be drawn through the groove past the valve into the Venturi passage. However, upon lifting the valve from its seat air as Well as detergent will be drawn into the Venturi passage and entrained with the water flowing therethrough.
Although the cylinder [5 serves in the present instance the dual purpose of a handle and a reservoir for detergent, it will be understood that the detergent may be contained in a reservoir remotely located which in turn may be connected by a conduit to the duct 33 in the needle valve member 3|.
