)

[0030] With reference to the Drawing, FIG. 1 shows an embodiment of the present invention in conjunction with a top-loading clothes washing machine 10. It should be understood that this is an example of one practical application, and that the liquid detergent dispensing arrangement of this invention could be employed with other automatic washing devices, e.g., a front-loading clothes washer, a dish washer, etc. FIG. 2 shows the same arrangement from the rear of the washer 10.

[0031] Here, the washing machine 10 has a cabinet or housing 12, in which there is a tub or drum in which the clothes undergo wash, rinse, and spin cycles. A mechanism 16 for rotating and oscillating the drum 14 and any associated clothes agitator (not shown) is represented schematically. A console or control panel 18 is situated at the back of the top deck of the cabinet, behind a lid or cover 20. The lid 20 is hinged or pivoted at the back so it can be lifted for access the drum 14.

Abstract

A liquid laundry detergent dispenser for an automatic washing machine employs a reservoir that holds a quantity of the detergent sufficient for numerous wash cycles. An air/fluid chamber fills through a check valve from the base of the reservoir. To commence a dispense cycle, a timer circuit is actuated to run an air pump that supplies air under pressure through an air hose to the air/fluid chamber, and this displaces the detergent from the chamber and through a detergent dispense hose into the tub or drum of the washing machine. At the end of the dispense cycle, a bleed valve opens to relieve pressure on the air hose and the air/fluid chamber. The automatic detergent dispenser can be attached to existing washers or built in. A multiple arrangement can be used with a bank of washers at a commercial laundry.

The disclosure of such provisional application is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] This invention is directed to the automatic washing machines, e.g., for clothes washing and laundry, although the principles could be applied to dishwashers and other automated washing or cleansing systems. The invention is more particularly concerned with systems and devices for automatically injecting a measured amount of detergent and moving it from a storage tank or container into the washing machine. [0003] Automatic washing machines have been used commercially and in homes for many decades. In each case, the user has to measure and dispense a quantity of detergent into the machine at the commencement of a wash cycle. There is always human error in administering the detergent to the machine, and often too much detergent is dispensed. Further, it is inconvenient for the user to ...
