United States Patent Ofiice 3,371,370 DISHWASHING APPARATUS Edward J. Feser, 8862 Arcadia Ave, San Gabriel, Calif. 91775 Filed Oct. 22, 1965, Ser. No. 501,730 6 Claims. (Cl. 401-46) ABSTRACT OF THE DISCLOSURE A hand operated dishwashing apparatus which is adapted to be attached to a 'source of water and which includes a reservoir of detergent. The apparatus further includes manual control means for positioning within the apparatus and discharging a predetermined amount of detergent into a stream of water adjacent a brush portion of the dishwashing apparatus.

This invention relates to a dishwashing apparatus which can be readily attached to an ordinary faucet, and more particularly a dishwashing apparatus that contains an integral detergent reservoir and manually operable means for releasing a metered amount of detergent.

Prior to my invention dishwashing apparatuses were often comprised of complicated and expensive equipment. Such equipment required special installation and large amounts of detergent, and was both expensive to install and to use. On the other hand, simple brushes did not provide effective mechanically assisted means for Washing dishes.

Hence, there was not available a satisfactory, easily installed, dishwashing apparatus that was self-contained and yet was not a complicated mechanism requiring separate installation and large amounts of detergent to be used during its operation. Therefore, people who did not wish to install a permanently afiixed, complicated mechanism, generally had no suitable apparatus for mechanically washing dishes, and had to resort to ordinary scrub brushes.

It is a primary object of my invention to alleviate these and other disadvantages in the prior art by providing a dishwashing apparatus comprising a combination brush having an integral, controllable detergent reservoir and a means for spraying washing fluid adjacent to the bristles of the brush.

Another object of this invention is to provide dishwashing apparatus which is easy to use, and which does not require complicated installation for its operation.

Still another object of this invention is to provide dish- -washing apparatus containing an integrally supported detergent reservoir which can be attached to existing faucets by means of a simple coupling attachment.

A further object of this invention is to provide dishwashing apparatus consisting of a brush with a hollow handle that has a detergent reservoir and means by which the detergent can be supplied in metered quantities.

Other objects and advantages of my invention will become apparent from the following illustrative description.

Generally, my dishwashing apparatus includes a brush, a hollow handle element communicating with said brush, and a detergent reservoir formed in said handle element. Remote from the brush, a fluid inlet is provided on the handle element, to which is attached a flexible water conduit. The conduit extends to a valve connected to a water faucet. The valve is preferably adjustable so that water can either be directed through the conduit to the handle element and brush, or through a bypass outlet to a sink.

The handle element also includes a slidable piston movable from a detergent loading position to a detergent mixing positon. The piston pumps fluid detergent from the reservoir in metered amounts to the brush for intermixing with water for the washing operation.

Referring more particularly to the drawings, the brush element is generally designated '12, and the elongated hollow handle element is designated 13.

The brush element 12 includes a mixing chamber 15, having a bottom plate 15a, with spray outlets 16. An outside portion of hollow handle 13 defines the periphery of cylindrical detergent reservoir 18. It surrounds a separate inner hollow portion that includes rigid tube 19. Tube 19 provides a passageway through which washing fluid can flow from fluid inlet 17 to spray outlets 16. Detergent reservoir 18 is closed at its end adjacent brush 12 by muzzle ring 20, and at its other end by a filling valve to be subsequently described. Junction ferrule 22 connects the end of rigid tube 19 near muzzle ring 20 to mixing chamber 15. Fluid leakage is prevented by resilient annular seal 20a surrounding tube 19, and seal 2% peripherally located on muzzle ring 20. Spray outlets 16 from mixing chamber 15 are preferably arranged in a circle and, in turn, are encircled by bristles 23. By means of suitable deflection tabs 24, which restrict spray outlets 16, sprayed fluid from outlets 16 can be directed onto adjacent bristles 23.

A modification of the detergent reservoir end sealing means is shown in FIGURE 14, where a rubber bushing 20c is substituted for muzzle ring 20 and annular seal 2017.

In tube 19, between fluid inlet 17 and spray outlets 16, is a detergent admission port 25 that opens into annular detergent cylinder chamber 26. Detergent cylinder chamber 26 is defined by the space between the opposing dishwashing s rt s peripheral surfaces on the exterior of tube 19 and interior rigid tube 19 and is axially slidable thereon. Its movement is limited by tongue 32 which extends inwardly from an end of piston 31 remote from cylinder chamber 26 into recess 33 in rigid tube 19. A sealed slidable fit is provided between detergent piston 31 and detergent cylinder chamber 26 within which it is fitted.

Piston 31 is slidably responsive to fluid pressure changes within cylinder chamber 26. It moves within cylinder chamber 26 from a detergent loading position, as shown in FIGURE 8, where detergent cylinder chamber 26 only communicates with detergent reservoir 18, through detergent cylinder chamber loading ports 29, and a detergent ejection position, as shown in FIGURE 9, where detergent cylinder chamber 26 only communicates with rigid tube 19 through detergent admission port 25. Thus, movement of cylindrical member 27 toward inlet 17 will cause fluid pressure to increase within detergent cylinder chamber 26, and piston 31 to move in response thereto. The relative location of piston 31, detergent admission port 25 and loading ports 29, is such that piston 31 blocks detergent admission port 25 in the detergent loading position, as shown in FIGURE 8, and blocks detergent loading ports 29 in the detergent ejection position, as shown in FIG- URE 9.

Finger bar 39 projects from opposite sides of hollow handle 13 close enough to hand heel suction cup 41 that it can be gripped by the fingers of a persons hand, the heel of which is placed on suction cup 41. Since increased squeezing of the finger grip 39 and suction cup 41 will cause detergent reservoir 18 to slide axially along hollow handle 13, these elements will be referred to as a plunger means. Detergent reservoir 18 is slidably urged toward spray outlet end of hollow handle 13 by resilient spring 43 to the position shown in FIGURES and 8.

Located on the end of detergent reservoir 18, remote from ring 20, is a filling valve which includes a disc .45 having filling ports 46. Adjacent to disc 45 is funnel 47, which can be rotated around tube 19. Funnel 47 has a plurality of filling ports 48 in its bottom portion, which can be turned so as to coincide with filling ports 46 in adjacent dis-c 45 of detergent reservoir 18, as shown in FIGURE 7, or by rotating funnel 47, close filling ports 46 by covering them with solid portions in the bottom of funnel 47.

In another embodiment of this invention shown in FIGURE 12, the filling valve is comprised of an elastomeric valve closing cup 50 tightly fitted around rigid tube 19 within detergent reservoir 18, and adjacent thereto is an elastomeric split valve disc 52 (which is a solid piece of material fitted around tube 19 from which radial splits 52a extend, as shown in FIGURE 13) and perforated valve disc 54. The valve discs 52 and 54 are in the bottom of funnel 47. Filling ports 55 are provided in valve disc 54, which is in turn resiliently urged by abutting spring 43 toward the junction of funnel 47, and adjacent closing cup 50. In the closed position, split valve disc 52, in combination with annular washer 56, forms a fluid-tight seal between closing cup 50 and filling ports 55 of valve disc 54. When this filling valve is opened by squeezing finger bar 39 and suction cup 41 together, closing cup 50 is separated from split disc 52, so that detergent under pressure can be forced through filling ports 55 between the splits 52a into detergent reservoir 18. That is, when pressure is released from resilient split valve disc 52, by separating closing cup 50 therefrom, the splits can be bent to increase their size so that an unobstructed passageway between the members is provided.

Attached to fluid inlet 17 of hollow handle 13 is flexible connector tube 61, which provides a conduit for directing fluid from a fluid source such as water faucet 65. Adapter valve 67, secured to the faucet 65, includes a connection nipple 67a, to which the end of connector tube 61 is secured.

Fastener 68 provides the pivotal point for axial rotation of the valve 67 to move the valve to allow water to pass into conduit 61 or a bypass 69. Selector plate 63 contains a bypass outlet 69, through which water from water faucet 65 can be diverted by turning selector plate 63 to the position shown in FIGURE 3. The turning movement of selector plate 63 is limited by movement of stud 71, which projects through curved slot 73. When turned to the position shown in FIGURE 4, water can flow from the attached water faucet 65 through conduit or tube 61. Water from bypass 69 is absolutely detergent free.

In operation, the detergent reservoir 18 is filled with a suitable amount of fluid detergent through filling valve 45, which is opened by turning funnel 47 in the embodiment shown in FIGURES 5, 6 and 7, or by squeezing the plunger means in the embodiment shown in FIGURE 12.

Faucet 65 is turned on and selector plate 63 is opened so that water will flow down conduit 61, through rigid tube 19 within hollow handle 13, and be sprayed out spray outlets 16. Water of desired temperature and quantity is controlled through faucet 65.

By gripping the device so that suction cup brace 41 is seated in the heel of a hand, and the fingers of the hand grasp finger bar 39, a person can squeeze the plunger means so as to cause detergent reservoir 18 to slide axially along hollow handle 13. As the plunger means is squeezed, piston 31 moves within detergent cylinder chamber 26, causing detergent admission port 25 to open, detergent loading ports 29 to close, and fluid detergent contained within detergent cylinder chamber 26 to be ejected through detergent admission port 25 into rigid tube 19. The fluid detergent is mixed with water flowing through rigid tube 19 into mixing chamber 15, and is sprayed out spray outlets 16 adjacent bristles 23 for the washing operation. Releasing the plunger means causes spring 43 to urge detergent reservoir 18 to slide back toward mixing chamber 15, piston 31 to move from detergent cylinder chamber 26, detergent admission port 25 to close, and detergent loading ports 31 to open so that fluid detergent within detergent reservoir 18 can flow into and fill detergent cylinder chamber 26.

When the plunger means is squeezed, the amount of fluid detergent ejected into rigid tube 19 is limited to the amount carried in detergent cylinder 26. Thus, a metering system is provided for the fluid detergent. Each time the plunger means is squeezed, additional quantities of detergent are ejected in increments equal to the capacity of the detergent cylinder chamber 26. When the plunger means is released, detergent cylinder chamber 26 is filled with detergent which flows from detergent reservoir 18.

The dishwashing apparatus herein described can be made from a wide variety of materials so long as they are sufficiently durable to withstand the abuse of normal usage. It is deemed preferable, however, to make the exterior of the detergent reservoir of a clear plastic so that it can be visually ascertained when it needs to be refilled with fluid detergent. The parts of the apparatus which are in sliding engagement with each other should preferably be made of sturdy, relatively smooth material to lessen frictional drag, and the sealed portions should provide fluid-tight engagement of the associated members.

In operation closing cup 50 is so positioned on tube 19 that it opens port 55 in disc 54 when bar 39 and cup 41 are squeezed together. A dual function is therefore accomplished in that the ports 55 are opened to permit filling and the detergent admission port 25 is closed during this operation to prevent passage of water into the detergent reservoir 18.

The dishwashing apparatus when normally used in an inclined position, with the brush down, prevents detergent spillage from the apparatus and also permits easy gravity loading of the reservoir with liquid detergent.
