5 Claims, 5 Drawing Figures 1 MANUALLY OPERATED WASHING DEVICE This invention relates to a manual washing device adapted to apply either water or detergent or both to an article to be washed. The device of the invention is particularly suitable for washing cups, glasses and dishes.

Various manual washing devices have been designed for use in washing dishes. The devices usually have either separate controls for water and detergent, or else have a control only for detergent, with no water control. In general they are awkward to use.

Accordingly, the invention provides a device that can conveniently be held in one hand and which has a single control which can be operated to apply either water or detergent or both to an article to be washed.

In a preferred embodiment of the invention this is achieved by providing a detergent dispenser having a detergent pump therein, and a water conduit having a water tap therein. A single control member is provided which when moved in one direction operates the detergent pump and which when moved in another direction operates the water tap. The two movements of the control member are independent of each other, so that the control member may be moved in either of the two directions or in a third direction representing a combination of the first two directions, thereby applying either water or detergent or both to the article to be washed.

In a preferred embodiment the invention also provides separate means for increasing the flow of water when the article being washed is to be rinsed and a brush that can be removed and replaced in any one of a number of positions, to increase the life of the brush.

Further objects and advantages of the invention will appear from the following description, taken together with the accompanying drawings, in which:

FIG. l is a side view of a preferred washing device according to the invention;

FIG. 2 is a sectional elevation of a water valve of the washing device of FIG. 1;

FIG. 3 is a perspective exploded view of portions of the control linkage used to operate the water valve and detergent pump of the washing device;

FIG. 4 is a side view, partly in section, of the brush of the washing device of FIG. I mounted on the water conduit, the bristles of the brush being omitted for clarity; and

FIG. 5 is a perspective view showing the base of the brush base member in position to be mounted on the water conduit of the washing device.

Reference is first made to FIG. 1, which shows a preferred washing device 8. The washing device 8 includes a cylindrical detergent dispenser it) covered with a high friction material 12 such as cork, rubber or cloth, so that the detergent dispenser forms a non-slip handle for the washing device. The detergent dispenser may be opened for filling with detergent by unscrewing a conventional cap 16. The detergent dispenser includes a conventional pump 18, of the kind found in bottles for window washing solution and the like. The pump 18 includes a plunger 20 which, when depressed in the direction of arrow A, forces detergent from the detergent dispenser through a flexible plastic hose 22. Since the pump 18 is entirely conventional, its construction will not be described.

A separate water conduit 24 extends through the detergent dispenser. The conduit 24 includes at one end thereof a threaded connector 26 which can be connected to a hose to a water supply. The conduit 24 extends through the detergent dispenser 10, then out through the end of the detergent dispenser from which the 'pump plunger 20 projects, and then is angled at 27 and extends to a free end 28. A brush generally indicated at 30 is mounted on the free end 28. As shown in FIG. 4, the free end 28 of the water conduit 24 includes a number of small holes 32 and a number of larger holes 33 for spraying water into the brush bristles, as will be explained. Except for

holes

32, 33, free end 28 is closed.

The means by which the flow of water and detergent is controlled will next be described, following which the detailed manner in which the brush 30 mounts on the water conduit 24 will be described.

As shown in FIGS. 1 to 3, flow of water through the water conduit 24 is controlled by a push valve generally indicated at 34. The push valve is: conventional and includes an inlet aperture 36, an outlet aperture 38, and a valve disc 40. The valve disc 40 can be depressed to close off the flow of water between the inlet and

outlet apertures

36, 38 and when raised permits flow of water through the conduit 24. The valve disc 40 is operated by a push button 42 screwed onto the top of a valve stem 44 connected to the valve disc 40. A coil spring 46 encircling the valve stem normally biases the valve to its open position.

An operating member 48 is provided for the water valve 34 and for the detergent pump 18. This operating member 48 is connected to the water valve 34 and detergent pump 18 by a linkage generally indicated at 50. The linkage 50 includes a push lever 52 having a slot 54 therein to accommodate the valve stem 44. The push lever 52 is spaced below the operating member 48 and is secured thereto (by welding or by forming as one piece). Located in the space 56 between push lever 52 and operating member 48 is the valve push button 42. The valve stem 44 extends downwardly through the slot 54, so that when the operating member 48 is depressed in the direction of arrow B, it shuts off the flow of water through the conduit 24.

To operate the detergent pump 18, the linkage 50 includes a separate pump lever 60 pivotally mounted at 62 on a collar 64 secured (by screws or adhesive) on the water conduit 24. The water conduit 24 extends through an aperture 65 in the pump lever 60. The top end of the pump lever 60 is forked at 66, and shoulders 68 of the push lever 52 bear against the forks 66. A tongue 70 of the push lever 52 extends through the forks 66 to prevent pivoting of the push lever. The bottom end of the pump lever 60 includes curved forks 72 which bear against the plunger 20 of the detergent pump and through which detergent hose 22 extends. Thus, when the operating member 48 is pushed forwardly, the bottom forks 72 of the pump lever 60 move in the direction of arrow A, depressing the detergent plunger 20 and forcing detergent through the plastic detergent hose 22. When the operating member 48 is released, the spring (not shown) in the detergent pump 18 will force the forks 72 of the pump lever forwardly returning the operating member 48 to its rearmost position. The forward and rearward movement of operating member 48 does not affect the water valve 34, because the valve push button 42 simply slides in the space 56 and the valve stem 44 slides in the slot 54.

In summary at this point, the operating member 48 may be moved vertically to control water flow through the brush, and may be moved forwardly and rearwardly to control the flow of detergent to be applied to the article being washed. The two movements are quite independent, but both can be effected together if it is desired to apply both water and detergent to the article being washed.

In order to lock the water valve 34 in an off condition, the push lever 52 includes a locking piece 74 which extends downwardly therefrom and which has at its bottom a curved rearwardly extending flange 76. When the operating member 48 is depressed in the direction of arrow B, it may then be moved rearwardly in the direction of arrow A to hook the curved flange 76 within a circumferential groove 80 (FIG. 2) provided in the base of the water tap 34. This prevents the spring 46 from lifting the valve disc 40 and holds the tap in an off position.

The manner in which the brush 30 is mounted on the water conduit 24 will next be explained, with particular reference to FIGS. 4 and 5. As shown, the brush includes a base member 82 having a central bore 84 and an enlarged bore 86 near the end 88 of the base member facing the detergent reservoir 10. The base member 82 is mounted on the free end 28 of the water conduit, with the free end 28 located snugly but slidably in the bore 84.

To hold the brush base member 82 in position on the water conduit, the water conduit includes a retaining ring 90 welded or soldered to its free end 28. The retaining ring 90 fits snugly but slidably Within the enlarged bore 86. The end 88 of the base member includes three slots 92, so that a screw 94 can be inserted through one of the slots 92 into a hole 95 in the retaining ring 90 to mount the base member 82 for limited sliding movement on the conduit 24. The base member 82 is biased forwardly (so that screw 94 normally sits at the rear of its slot 92) by a coil spring 96 encircling water conduit 24 and acting between the retaining ring 90 and the shoulder 98 separating the

bores

84, 86.

The brush 28 includes bristles 180 (shown only in FIG. 1) imbedded in the exterior of the base member 82 (by means not shown) and a plurality of passages 102 extending between the exterior of the base member 82 and the interior bore 84, to conduct water from the water conduit to the bristles. To inject water into the passages 102, the free end 28 of the water conduit 24 includes as described two sets of apertures, namely the first set of small apertures 32, and the second set of larger apertures 33. The

apertures

32, 33 are positioned so that when the brush base 82 is in its normal position (as drawn in FIG. 4) on the free end of the water conduit 24, the small apertures 32 are aligned with the passages 102. This is the washing position, and in this position a relatively small amount of water is allowed through the passages 102 to reach the article being washed.

For the rinse position more water is desired, and means are provided to pull the brush base member 82 rearwardly so that the larger apertures 33 are aligned with the passages 102. The pulling means comprises a lever 110 pivotally mounted on the water conduit 24 near the detergent dispenser 10. Connected to the lever 110 is a wire 112 running within a jacket 114. The jacket 114 is secured at its centre by a collar 116 secured to the water conduit and at its far end by a clamp 118 connected to the retaining ring 90. The wire 112 is connected to a pin 120 secured to the exterior of the brush base member 82, so that when the lever is depressed, the wire 112 is withdrawn and the brush base member 82 is drawn in the direction of arrow F, aligning the larger apertures 33 with the passages 102. When the lever 110 is released, the spring 96 returns the brush base member 82 to the position drawn in FIG. 4.

The detergent hose 22 extends through a slot 122 in retaining ring 90 and then through a guide conduit 124 near the surface of the interior of brush base member 82. A tip 126 of the detergent hose 22 protrudes from the front of the brush base member 82. From tip 126, detergent is applied directly to an article being washed.

In order that the brush may be rotated after it has become worn on one side, two additional guide conduits 124 are provided in the brush base member 82 and two additional slots 122 are provided in the retaining ring 90. Thus, when the brush has become worn on one side, the screw 94 can be removed, and the brush can be removed from the water conduit and replaced in a position rotated degrees from its previous position. In that event, the detergent hose 22 will extend through a new one of the guide conduits 124 and the wire 112 will be secured to a new one of the pins 120 (of which three are provided).

It will be seen that since the user grips the detergent dispenser 10 and not the conduit 24, the users hand is insulated from the conduit 24 (which can become hot when hot water is used). The covering 12 of the detergent dispenser is heat resistant and also provides addi tional insulation.
