Washing machine fill system
BACKGROUND OF THE INVENTION 
     The present invention relates to water fill systems for automatic washing machines and particularly machines of the type having a receptacle filled with water and having a motorized agitator for moving the articles immersed in the water for washing. Washing machines of this type typically have an inlet valve with dual inlets for individual connection to a source of heated and cold Water to provide mixing and a flow tempered water for washing in the receptacle. The inlet mixing valves commonly employed for a washing machine are of the type electrically actuated with individual solenoid operators for opening the inlet for the heated and/or cold water. The valves have a single outlet for the tempered water discharged to the washing receptacle or tub. 
     In providing for the manufacture of automatic washing machines, it has heretofore been the practice to mount the electrically operated water inlet mixing valve on the machine cabinet or housing with the inlet fittings extending therethrough for connection to externally of the machine to the hot and cold water sources. This has required wiring connections from the electrically operated mixing valve to the programmer timer for controlling the washing machine cycle of operations. Typically, the programmer and timer controls are located above the machine top deck in a console; whereas, the electrically operated water valve is located below the top deck in the region adjacent the washing receptacle and is thus subject to moisture and water from hose leakages and receptacle overflow. Thus, it has been desired to provide a way or means of preventing the wiring connections to the electrically operated water inlet valve in a washing machine in a manner which protects the electrical connections from moisture and water leaks which would result in electrical shorting and result in premature failure of the coil. 
     SUMMARY OF THE INVENTION 
     The present invention provides a unique and novel way of mounting an electrically operated water inlet mixing valve in a washing machine such that the electrical connections are isolated from the chambers of the machine connected to the water supply and yet provide tempered water at the valve outlet for discharge into the washing receptacle of the machine. The water inlet mixing valve of the present invention has individual solenoids for operating separate hot and cold water valve members; and, the solenoids extend outwardly from the mounting deck surface provided on the valve. The mounting deck may either comprise a plate attached to the valve body or a surface molded integrally in the valve body around the solenoids. The separate hot and cold inlet fittings and tempered water discharge fitting extend from the valve body in the region below the mounting deck surface. The valve is mounted to the undersurface of the machine cabinet top deck with the solenoids extending upwardly through an aperture formed in the machine deck into the control console of the machine which is located above the top deck. The separate inlet fittings for the valve extend outwardly of the machine cabinet through an aperture provided in one wall of the machine cabinet. The valve mounting deck may be sealed about the undersurface of the machine cabinet top deck to therefor prevent moisture or water discharge from a broken fitting or a hose from entering the chamber containing the electrical connections to the valve solenoids. 
     The present invention thus provides a unique and low cost technique for mounting a dual solenoid water inlet mixing valve into a washing machine cabinet directly in a manner which isolates the solenoids and their attendant electrical connections from the chambers connected to the water inlet and outlet fittings.

     DETAILED DESCRIPTION 
     Referring to FIG. 1, a typical top loading washing machine is illustrated generally at 10 as having a top deck 12 with a control console extending upwardly therefrom at the rear thereof as indicated generally at 14 with a control panel 16 having user operated controls such as program setting knob 18 extending therefrom. The top deck 12 has a hinged cover or lid 20 which is user openable for loading therein articles to be washed. 
     The machine cabinet has a front panel 22, left side panel 24 right side panel 26 with a back panel 28. The machine has a washing tub or receptacle 30 having a motorized agitator 32 provided therein it will be understood that the programmer/timer and controls for operating the agitating motor and other machine functions are disposed within the control console 14 above the top deck 12 of the cabinet 10. 
     Referring to FIGS. 2-5, a water inlet mixing valve indicated generally at 34 has a mounting deck surface 36 which in the embodiment of FIG. 2 comprises a deck plate 38 attached to the valve body 40 by fasteners such as self-tapping screws 42. The valve 34 has a pair of solenoid operators extending upwardly from the mounting surface 36 as indicated generally by reference numerals 44,46 each of which has a pair of preferably bayonet type electrical connecting terminals indicated respectively at reference numerals 48,50. 
     The valve body 40 has separate hot and cold water inlet fittings denoted by reference numerals 52,54 extending from a common side of the body 40 and at right angles to the solenoid operators 44,46 and which are of the type threaded for hose connection thereto. The valve block has a common outlet fitting 56 for providing discharge of tempered, hot or cold water depending upon the sequence and duration of energization of the solenoids 44,46. The outlet fitting also extends at right angles to the solenoids 44,46 and from a face of the body adjacent the common inlet side. 
     Referring to FIGS. 3, 4 and 5, the top deck 12 of the cabinet 10 has an aperture 57 formed therein; and, the back panel 28 of the cabinet 10 has an aperture 58 formed therein. The valve is installed with the solenoids 44,46 received through the aperture 57 in the deck plate 12 and the inlet fittings 52,54 received through the aperture 58 in the back panel 28. The deck surface 36 of the valve is registered against the under surface of the cabinet top deck 12; and, the valve is secured in place by suitable fasteners such as, for example, screws 60 threaded into the deck plate 38. If desired, a resilient seal denoted by reference numeral 59 in FIG. 4 and FIG. 7 may be employed between the valve deck 36 and undersurface of top 12 of the cabinet. The outlet fitting 56 of the valve is connected to a hose 62 which is positioned for discharging into the wash tub or receptacle 30. 
     Referring to FIG. 6, an alternate embodiment of the mixing valve is indicated generally at 134 and has a body 140 a portion of which is shown in FIG. 6 and which has molded integrally therewith a mounting deck 136 upon which is mounted the solenoid coils or operators one of which is shown in FIG. 6 and indicated generally at 144. The valve has the inlets thereof disposed in parallel arrangement from one side, one of which is illustrated and denoted by reference number 152 in FIG. 6. The outlet of the valve 134 is disposed at right angles from the end of the valve as denoted by reference numeral 156. It will be understood that the valve of FIG. 6 may be mounted to the washing machine cabinet 10 in the same manner as is illustrated in FIGS. 3, 4 and 5. The present invention thus provides a low cost and convenient way of mounting a water inlet mixing valve in a washing machine such that the electrical operators for the individual valving operations are disposed above the top deck of the machine cabinet and housed in the control console. The body of the valve and the inlet and outlet fittings are disposed below and sealed against the undersurface of the top deck of the machine and thus the electrical connections are isolated and protected from the hose connections to the valve inlet and outlet and overflow from the tub. 
     Although the present invention has hereinabove been described with respect to the embodiments illustrated in the drawings, it will be understood that the invention is capable of modification and variation and is limited only by the following claims.
