Patent Images
1. A laundry treating appliance for treating laundry in accordance with an automatic cycle of operation comprising:
- 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 comprising;
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;
wherein 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 platform to erode a portion of the solid block to form a mixture of liquid and treating chemistry, and the mixture is supplied to the tub through the liquid outlet.

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.
