DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings the numeral 10 generally designates a clothes washer using a lid assembly 68 having the fluid dispenser of the present invention. Washer 10 includes a cabinet 12 having side walls 14 , a front wall 16 and a top wall 18 . Top wall 18 includes a horizontal portion 20 and an inclined portion 22 which extends downwardly and forwardly from the front edge of the horizontal portion 20 . The top wall 18 is provided by a top cover 24 having a rear edge 26 , side edges 28 , 30 , and a front edge 32 . A juncture or bend 34 divides the horizontal portion 20 from the inclined portion 22 of the top surface of the top cover 24 .

Provided within top cover 24 is a door depression 36 having a rear edge 38 , side edges 40 , 42 and a front edge 43 . Extending upwardly and rearwardly from the front edge 43 is a lip flange 44 having a lower front edge 46 which extends upwardly and rearwardly to a ridge 48 . Ridge 48 includes opposite ends 50 , 52 and an intermediate portion 54 . Intermediate portion 54 is slightly below the ends 50 , 52 and is also positioned forwardly from ends 50 , 52 .

Extending downwardly and inwardly from ridge 48 is a generally circular skirt 56 having a front drain surface 58 , side drain surfaces 60 , 62 , and a rear drain surface 64 all of which surround an access opening 66 .

Top lid assembly 68 is comprised of a metal lid frame 70 and a plastic dispenser housing 72 which are detachably secured together. Plastic dispenser housing 72 includes a gasket seal 74 (FIG. 1 ), and a fluid chamber formed by a reservoir chamber wall 76 and a dispensing chamber wall 78 . Gasket seal 74 is elongated and includes a left end 96 and a right end 98 . As best shown in FIGS. 1 and 3 , gasket seal 74 extends across the front of the washer door depression 36 and generally across the ridge 48 . The gasket seal 74 retains condensation in the area of the door depression 36 and also provides a reduction in agitation noise that otherwise might escape from the access opening 66 of the washer 10 .

A reservoir viewing window 80 is provided in reservoir chamber wall 76 and a dispensing viewing window 82 is provided in dispenser chamber wall 78 . A sliding indicator or gage 84 is mounted on a track associated with window 82 and is operable for movement along the length of the dispenser viewing window 82 . The sliding indicator 84 can be manually set as a marker at any of a plurality of positions along the length of the window 82 . Plastic dispenser housing 72 also includes a fill cap 86 which is detachably mounted over a fill opening 87 and a dispenser button 88 for dispensing fluid 90 from the dispensing chamber in a manner to be described in more detail hereafter.

Metal lid frame 70 includes a horizontal surface 92 (when the lid is in its closed position) and an inclined surface 94 .

Behind reservoir chamber wall 76 is a reservoir chamber 100 (FIG. 4 ), and behind dispenser wall 78 is a dispensing chamber 102 (FIG. 7 ). Dispensing chamber 102 is contained within reservoir chamber 100 and includes side walls 104 , a rear wall 106 , and a dispenser spout 108 which provides a dispenser opening for permitting fluid to exit from dispenser chamber 102 . The portion of the dispensing chamber 102 formed by walls 104 and 106 is attached to front wall 76 by an interference fit and a slight amount of fluid can leak by the attachment point.

Within reservoir chamber 100 are several stand offs 110 , 112 which provide structural support to the walls within the reservoir chamber 100 .

Referring now to FIG. 15 , the fill opening 87 is shown without fill cap 86 in place. With the lid assembly 68 in the generally vertical posture of FIGS. 1 and 5 , the fill opening 87 is formed with a downwardly angled entry portion 89 through wall 76 and a substantially horizontally disposed cylindrical exit portion 91 . The back edge 93 of the exit portion 91 is in close proximity to and generally parallel to the back wall 99 of the reservoir chamber 100 . When fluid is poured into the fill opening 87 , it will flow into the exit portion 91 and will enter the reservoir chamber 100 . The fill can continue until fluid is observed at the lower lip of exit portion 91 at which point the reservoir chamber 100 is full. When the lid assembly 68 is in the closed horizontal posture of FIG. 4 , the fluid in the reservoir chamber 100 will always be below the back edge 93 of the exit portion 91 . Thus, if the operator should forget to replace the fill cap 86 , there would not be any spilling of fluid out the fill opening 87 . In fact, fill cap 86 could be left off if desired. Further shown in FIG. 15 is a vent opening 101 that allows the reservoir chamber 100 to breath freely preventing any airlock condition.

Plastic housing 72 is nested within the metal lid frame 70 and is fitted beneath the curled front edge 114 . The peripheral edges of the housing 72 rest on the side edges 144 , 146 ( FIG. 13 ) and rear edge 148 of the metal lid frame 70 . The front edge 116 of the plastic housing 72 nests under the front curled edge 114 of the lid frame 70 .

Referring to FIGS. 10 and 11 , a valve assembly 117 comprises a valve stem 118 having an upper end 120 . Dispenser button 88 is fitted over the upper end 120 and includes a sealing flange 122 thereon. Valve stem 118 includes a valving flange 124 and a retaining flange 126 . A coil spring 128 is fitted over the lower end of the valve stem 118 . The valve assembly 117 is fitted within a valve receiving bore 130 in the housing 72 . A retaining clip 132 is fitted within a retaining clip slot 134 and includes clip fingers 136 ( FIG. 12 ) which retentively engage the retaining flange 126 to hold the valve assembly 117 within valve receiving bore 130 . The clip fingers 136 of retaining clip 132 are yieldably movable toward one another to permit the clip 132 to be removed so as to permit removal of the valve assembly 117 . This permits the easy removal of the valve assembly 117 for cleaning.

Referring to FIG. 11 a dispenser port 138 provides communication from dispensing chamber 102 to the valve receiving bore 130 . Fluid is permitted to enter the axial space between the valving flange 124 and the sealing flange 122 . Depression of button 88 causes the valving flange 124 to move to the left of the dispenser spout 108 as viewed in FIG. 11 thereby permitting fluid to flow out of the dispenser spout 108 . Removal of pressure from the button 88 permits the spring 128 to return the valve flange 124 to its original position, thereby cutting off the flow of fluid from the dispenser chamber 102 .

FIGS. 7 , 8 , and 9 illustrate the method of using the dispenser chamber 102 and the reservoir chamber 100 of the present invention. Initially the lid assembly 68 is moved to its up-standing position shown in FIG. 7 . The fill cap 86 is removed and fluid such as liquid detergent is poured into the reservoir chamber 100 until fluid is observed at the lower lip or exit portion 91 of the fill opening 87 . As can be seen in FIG. 6 , the front walls 76 , 78 of the chambers 100 , 102 are inclined toward the dispensing chamber 102 thereby causing any fluid within chamber 100 to move toward the dispensing chamber 102 when the lid assembly 68 is lowered.

As can be seen in FIG. 7 the initial filling of the reservoir chamber 100 does not cause any substantial amount of fluid to be within the dispensing chamber 102 . However, when the lid assembly 68 is moved to its closed position ( FIG. 8 ) the fluid within chamber 100 flows around the rear wall 106 and both of the side walls 104 of chamber 102 and enters chamber 102 through a charging opening 107 adjacent the rear wall 106 . Returning the lid assembly 68 to its upright position as shown in FIG. 9 causes the dispenser chamber 102 to be full and ready for dispensing fluid through spout 108 .

The operator then depresses the button 88 and observes through window 82 as the fluid level lowers within dispenser chamber 102 . The operator can determine, by dispensing a predetermined quantity of fluid into a measuring container, what the level of the fluid within the dispensing chamber should be after the proper amount has been dispensed. The operator can then move the sliding indicator 84 to mark that position and thereafter can release the button 88 when the level of fluid reaches the level of the sliding indicator 84 . Thus, the sliding indicator 84 is set to the proper level for a particular brand or concentration of detergent.

On occasion the detergent may clog or foul the valve assembly 117 . This can easily be remedied by pulling out clip 132 and removing the valve assembly for cleaning. The valve assembly 117 can then be reinserted, and the clip 132 is inserted to retain the valve assembly 117 in position for operation.

Referring to FIGS. 13 and 14 , the present invention utilizes a novel means for attaching the plastic housing 72 to the metal lid frame 70 . Two L-shaped brackets 140 , 142 are fitted in the rear corners of the metal lid frame 70 under the edges 144 , 146 , 148 as shown in FIGS. 13 and 14 . L-shaped brackets 140 , 142 are each provided with elongated slots 150 and are also provided with a bushing 170 which fits within a spring hole 172 of the metal lid frame 70 . Bushing 170 includes a cylindrical bore extending therethrough and a torsion rod spring 152 is fitted through the bore in bushing 170 . Torsion rod spring 152 includes a first end 154 and a second end 156 (FIG. 13 ). The second end 156 engages the L-shaped bracket 140 , and the first end 154 is outside the top lid assembly 68 and is adapted to engage the underside of top cover 24 to provide a counter balance to the lid assembly, counter balancing the weight provided by the fluid in the reservoir and dispensing chambers 100 and 102 .

A center link clamp 158 is clamped over the torsion rod spring 152 between the two L-shaped brackets 140 , 142 so as to lock the L-shaped brackets beneath the curled lip flanges 144 , 146 on the sides of metal lid frame 70 . The spring 152 is held to the L-shaped brackets 140 , 142 and the center link clamp 158 by spring finger clamps 174 .

Four retainer pegs 160 each include a slot 162 , a shank 164 and an elongated tab 166 . These pegs 160 are fitted within holes 168 in housing 72 and the elongated tabs 166 fit within the elongated slots 150 of the L-shaped brackets 140 , 142 . Rotation of the pegs 160 causes the elongated tabs 166 to turn below the slots 150 so as to retentively attach the housing 72 within the metal lid frame 70 . This attachment of the housing 72 to the frame 70 allows quick removal of the housing 72 so that it may be taken to a sink for flushing or cleaning should it become clogged by liquid detergents or their residue. Further, the unique system for attachment of the housing 72 to the lid frame 70 allows the housing 72 to be easily installed as an accessory since the same lid frame is used with or without the housing 72
