Benefits of technology

[0004]According to an embodiment of the invention, a laundry treating appliance for treating laundry in accordance with an automatic cycle of operation includes a tub defining an interior for retaining liquid, a liquid supply assembly in fluid communication with the tub and operable to supply liquid for use in treating laundry, and a dispenser assembly. The dispenser assembly includes a housing defining a chamber with a base, one or more support ribs located within the chamber and collectively defining an erosion platform located above the base that is configured to support a solid block of treating chemistry, a liquid flow channel extending at least partially along the one or more support ribs, a liquid inlet to the flow channel in fluid communication with the liquid supply assembly, and a liquid outlet from the flow channel in fluid communication with the tub. Liquid supplied to the liquid inlet enters the liquid flow channel and the liquid flow channel is configured to pass the liquid under the erosion ...

first embodiment

[0028]FIG. 1 is a perspective view of a laundry treating appliance 10 having a dispenser assembly 12 according to the invention. The laundry treating appliance is illustrated in the form of a vertical axis washing machine 10, and shares many features of a traditional automatic washing machine, which will not be described in detail except as necessary for a complete understanding of illustrative embodiments in accordance with the present disclosure.

[0029]As illustrated in FIG. 1, the washing machine 10 can include a housing 14 defining an interior 16. The housing 14 can be a cabinet, chassis, or both. A door or lid 18 is operably coupled with the housing 14 and is selectively moveable between opened and closed positions to close an opening in a top wall of the housing 14, which provides access to the interior 16 of the housing 14.

[0030]The housing 14 may also support the dispenser assembly 12 for dispensing treating chemistry during a cycle of operation. The dispenser assembly 12 may...

third embodiment

[0060]FIG. 7 is a schematic sectional view through a dispenser assembly 160 in accordance with the invention. The dispenser assembly 160 may be provided in a laundry treating appliance 162, such as the vertical axis washing machine 10 or the horizontal axis washing machine 150 described above, and shares many features in common with the dispenser assembly 12. The laundry treating appliance 162 is illustrated schematically, and shares many features of a traditional automatic washing machine, which will not be described in detail except as necessary for a complete understanding of illustrative embodiments in accordance with the present disclosure. As shown, the laundry treating appliance 162 includes a tub 164 configured to hold liquid and liquid supply assembly 166 is provided to supply liquid, such as water or a combination of water and one or more treating chemistries, into the tub.

[0061]The dispenser assembly 160 generally comprises a dispenser housing 168 that accommodates a bulk...

Abstract

A laundry treating appliance, such as a washing machine, either vertical or horizontal axis, can have a bulk dispenser assembly capable of dispensing multiple doses of treating chemistry from a bulk supply of treating chemistry. The bulk supply may be a solid block of treating chemistry held within a removable cartridge. A sensing assembly can be provided for determining the amount of treating chemistry that is dispensed from the bulk supply for a non-uniform dosing of treating chemistry.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application No. 62 / 116,970, filed Feb. 17, 2015, which is incorporated herein by reference in its entirety.BACKGROUND[0002]Laundry treating appliances, such as clothes washers, refreshers, and non-aqueous systems, can have a configuration based on a rotating drum that defines a treating chamber in which laundry items are placed for treating. Historically, residential or home-use versions of these appliances have single dose dispensers provided with compartment or cups, typically in a drawer or under a cover, in which the user of the appliance would fill with a dose of treating chemistry that was sufficient for the cycle of operation to be selected. Recently, bulk dispensers, i.e. dispensers holding multiple doses of a treating chemistry, have become more common, yet with single dose dispensers still being dominate.[0003]The bulk dispensers can be more convenient in that they re...
