Abstract
A chemistry dispensing assembly for a laundry appliance includes a reservoir that dispenses a laundry chemistry to a treatment chamber. A mixing channel is positioned below the reservoir that receives the laundry chemistry dispensed from the reservoir. A fluid assembly delivers a fluid carrier through a flow path that includes the mixing channel. The mixing channel is defined between an underside of the reservoir and an upper surface of the mixing channel.
Claims20
A chemistry dispensing assembly for an appliance, the chemistry dispensing assembly comprising:
- a mixing channel positioned below a cartridge housing, wherein the mixing channel is positioned to receive a laundry chemistry from the cartridge housing;
- a chemistry mixing section that is positioned below the cartridge housing and the mixing channel;
- a plurality of fluid nozzles that are configured to deliver a fluid carrier through a flow path that includes the mixing channel and the chemistry mixing section;
- and
- a ring fluid nozzle that delivers a separate mixing stream of the fluid carrier into the chemistry mixing section for further diluting the laundry chemistry to define a processing fluid that is configured to be delivered into a treatment chamber.
A chemistry dispensing assembly for an appliance, the chemistry dispensing assembly comprising:
- a mixing channel positioned below a reservoir and that selectively receives a laundry chemistry from the reservoir;
- a fluid assembly that delivers a fluid carrier through a flow path that includes the mixing channel, wherein the flow path is defined between an underside of the reservoir and an upper surface of the mixing channel;
- a chemistry mixing section that is separate from and positioned below the mixing channel that receives the fluid carrier and the laundry chemistry;
- and
- a ring fluid nozzle that delivers a separate mixing stream of the fluid carrier into the chemistry mixing section for further diluting the laundry chemistry to define a processing fluid that is delivered into a treatment chamber.
A chemistry dispensing assembly for an appliance, the chemistry dispensing assembly comprising:
- a mixing plate configured to receive a laundry chemistry dispensed from a removable laundry cartridge;
- and
- a fluid assembly that delivers a fluid carrier through a flow path that includes the mixing plate, wherein
- the laundry chemistry and the fluid carrier define a partially mixed solution that is delivered through perforations defined within the mixing plate and downward to a chemistry mixing section that is positioned below the mixing plate;
- a separate mixing stream of the fluid carrier is delivered into the chemistry mixing section to combine with the partially mixed solution to define a processing fluid that is delivered to a treatment chamber;
- and
- the chemistry mixing section includes a cyclonic structure that cooperates with the separate mixing stream of the fluid carrier to dilute the partially mixed solution to define the processing fluid.
