A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.

A combination washer/dryer including a tub. A heating circuit is positioned adjacent the tub. The heating circuit draws in drying air from adjacent the front end of the tub. The heating circuit has a duct system. The duct system moves drying air from an area adjacent the front of the tub to a rear end of the tub to enable the drying air to enter a rear end of a drum.

A laundry treating appliance and method for operating a laundry treating appliance having a housing; a treating chamber located within the housing. A duct fluidly coupling the treating chamber to an exterior of the housing with a vent located within the duct. The vent moveable between an open position where a fluid flow passes freely between the treating chamber and the exterior and a closed position where the treating chamber is fluidly isolated from the exterior.

A clothes dryer with improved heat dissipation efficiency of electronic components. The clothes dryer includes a cabinet having a clothes inlet, a drum rotatably provided in the cabinet, a drying fan configured to circulate air for drying supplied to the drum, and a heat dissipation duct. Wherein the heat dissipation plate includes a lower case fixed to the cabinet and provided with an airflow guide portion protruding toward the printed circuit board and an upper case coupled to an upper portion of the lower case and to which a printed circuit board on which a plurality of electronic components is mounted is fixed.

Disclosed is a dryer operating method that is useful in a 5G environment provided for the Internet of Things. The dryer of the disclosure includes a heating device, a tumbler connected to the exit of the heating device, a fan connected to the exit of the tumbler, a heat exchanger disposed in a flow line of a working fluid connected to the exit of the fan, and a compressor having an entrance connected to the flow line connected to the exit of the fan and an exit connected to the entrance of the heat exchanger. The method of the disclosure includes heating the working fluid using the heating device, reducing the pressure in the tumbler by discharging a portion of the working fluid in a circulation line to outside using the compressor, drying an object to be dried received in the tumbler, and cooling the object to be dried.

A dryer appliance may include a cabinet, a drum, a heater assembly, a temperature sensor, and a controller. The heater assembly may be in upstream fluid communication with a drying chamber. The temperature sensor may be in upstream fluid communication with the drying chamber. The controller may be in operable communication with the heater assembly and the temperature sensor. The controller may be configured to initiate a test cycle. The test cycle may include activating the heater assembly, detecting a first temperature upstream of the drum at a first moment following activating the heater assembly, detecting a second temperature upstream of the drum at a second moment following the first moment, determining a temperature delta as a difference between the second temperature and the first temperature, comparing the temperature delta to a delta threshold, and initiating an alert message based on comparing the temperature delta to the delta threshold.

A tub for a laundry appliance, includes a rear wall having a bearing hub for receiving a drive shaft. A plurality of inner radial walls extend from the bearing hub to a convergence wall. A circumferential wall extends concentrically about the bearing hub to engage one of the inner radial walls and the convergence wall. A plurality of outer diverging walls extends from the convergence wall to an outer edge of the rear wall.
