ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to a solid detergent bowl feeder for supplying diluted detergent to machines such as dishwashers and to a control equipment tray which is attached to the underside of the bowl.
Solid detergents used for dishwashers are conventionally placed in a bowl feeder, diluted by a water spray and fed into the machine or into a sink. The bowl feeder is typically mounted to the machine by the plumbing line fitting which is not a satisfactory solution since it results in the relatively heavy bowl containing a solid block of detergent being carried by a fitting of about one inch diameter. In addition, the faucet fitting supplying water to the bowl feeder is not always disposed on a convenient side of the feeder.
In most bowl feeder arrangements the control system, by which the adjustments are made to the feeder water and detergent concentrate supply, is separated from the bowl feeder in such a manner that access is not readily afforded to the controls for repair and replacement of parts or for resetting the duration of the spray.
The present bowl feeder and equipment tray assembly overcomes these and other disadvantages in a manner not revealed by the known prior art.
SUMMARY OF THE INVENTION
This invention provides a solid detergent bowl feeder having a seating arrangement which enhances the stability of the attachment to the washing machine or sink to which diluted detergent is supplied. In addition, the spray arm faucet fitting can conveniently be located optionally on either side of the bowl feeder and a float switch located on the other side of the bowl feeder.
The control equipment is provided in a tray which may be directly attached to the bowl feeder and is so arranged as to permit ready access to the tray control components and to facilitate a variable arrangement of control components.
This invention provides a solid bowl feeder comprising an outer wall including a lower rim providing a seating surface adapted to seat on a flat surface; and an inner wall spaced, at least in part, from the outer wall and defining a bowl including a first recessed portion having an upper seat adapted to receive a spray assembly.
It is an aspect of this invention to provide a spray assembly including a downspout portion and a radial arm portion communicating with downspout portion, the downspout portion including a upper seating portion seating on the recessed portion of the inner wall.
It is another aspect of this invention to provide that the inner wall includes a second recessed portion having an upper seat adapted to receive the spray assembly, said first and second seats providing optional seating locations for said spray assembly.
It is an aspect of this invention to provide a solid bowl feeder including an outer wall having a lower end and an inner wall defining a bowl; equipment tray including an outer wall having an upper end, and means for attaching the upper end of the tray to the lower end of the bowl.
It is yet another aspect of this invention to provide that the bowl outer wall includes a rim at the lower end; and the tray upper end includes a seating surface operatively seating the rim.
It is still another aspect of this invention to provide that the bowl outer wall and the tray outer wall are substantially in register.
It is another aspect of this invention to provide that the tray includes a cover and the bowl lower end seats on the cover.
It is an aspect of this invention to provide that the bowl includes an inner lower wall; the tray includes an inner upper wall; and the attachment means includes means connecting the inner lower wall of the bowl and the inner upper wall of the tray together.
It is still another aspect of this invention to provide that the bowl lower wall includes a spout; the tray upper wall includes an opening receiving the spout; and the attachment means includes a fitting connecting said spout to said tray.
It is yet another aspect of this invention to provide that the tray is adapted to receive a plurality of arrangements of control equipment.
It is an aspect of this invention to provide that the equipment tray includes interior programming means and accessible switching means cooperating to determine a selected spray period without accessing the interior of the equipment tray.
This solid bowl feeder and equipment tray assembly is relatively inexpensive to manufacture, easy to install and works well for its intended purpose.
