Abstract:
A pressure-driven metered treating chemistry dispensing pump for a laundry treating appliance having a housing having first, second and third chambers, with the first and second chambers each in fluid communication with the third chamber; a fluid inlet fluidly coupling a first fluid to the first chamber; an outlet fluidly coupled to the third chamber; a piston disposed in the housing; wherein, when the piston moves in a first direction in response to the first fluid entering the first chamber via the fluid inlet, the second chamber decreases in volume thereby ejecting at least some of the second fluid from the second chamber into the third chamber, and when the piston moves in a second direction, different from the first direction, the first chamber decreases in volume thereby ejecting at least some of the first fluid from the first chamber into the third chamber to mix the at least some of the first fluid and the at least some of the second fluid to form a mixture in the third chamber, which can be emitted through the outlet.
Abstract:
A method of operating a laundry treating appliance having a rotatable treating chamber in which laundry is received for treatment according to an automatic cycle of operation includes spraying a color care agent mixture comprising water and a color care agent onto the laundry to cover the laundry with the color care agent to protect the laundry from dyes released from the laundry as a result of supplying a wash mixture comprising a detergent and water to the laundry.
Abstract:
An example pressure-driven metered mixing dispensing pump includes a housing, a fluid inlet, a piston disposed in the housing at least partially defining first, second and third chambers, the first and second chambers each in fluid communication with the third chamber, the piston to, in response to first fluid entering the first chamber via the fluid inlet, move in a first direction to decrease the volume of the second chamber thereby ejecting second fluid from the second chamber into the third chamber, a spring to move the piston in a second direction to decrease the volume of the first chamber thereby ejecting at least some of the first fluid from the first chamber into the third chamber thereby mixing the at least some of the first fluid and the second fluid to form a mixture, and an outlet to discharge the mixture from the third chamber.
Abstract:
A method for wetting laundry in a laundry treating appliance having a rotatable treating chamber in which laundry is received for treatment according to an automatic cycle of operation comprises forming an annulus of laundry within the treating chamber prior to wetting the laundry, spraying liquid onto the annulus while the treating chamber is being rotated, after the formation of the annulus, redistributing the laundry, after the redistributing, rotating the treating chamber to form an annulus of laundry, and, while the treating chamber is rotated, recirculating the liquid through the laundry.
Abstract:
A pressure-driven metered mixing dispensing pump has a first chamber, a second chamber, a third chamber in fluid communication with the first and second chambers and a fluid outlet in fluid communication with the third chamber. Selectively supplying a first fluid into the first chamber causes at least a portion of the first fluid and at least a portion of second fluid supplied into the second chamber to be mixed in the third chamber and dispensed through the fluid 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.
