An appliance air/water handling system includes a rotating drum, airflow and fluid paths for directing process air and fluid, respectively, therethrough. First and second heat exchangers are in direct engagement with the airflow and fluid paths, respectively. A reversible refrigerant circuit delivers refrigerant through the first and second heat exchangers to alternatively define washing and drying conditions. In the washing condition the first heat exchanger cools the process air into cooled process air, and the second heat exchanger heats the fluid to define a heated fluid that is directed into the drum. In the drying condition the first heat exchanger heats the process air to define heated process air that is directed through the drum and through a third heat exchanger, and the second heat exchanger cools the fluid to define a cooled fluid that is directed to the third heat exchanger intersect with the heated process air.

Combination washing/drying laundry appliance having a heat pump system with reversible condensing and evaporating heat exchangers

A combination washer/dryer having a cabinet defining an interior, a tub provided within the interior, and a drum rotatably provided within the tub and defining a treating chamber, an induction coil carried by the tub and generating a magnetic field encompassing at least a portion of the container, and a cooling element providing on at least one of the tub or closure to form a cooled surface in fluid communication with the treating chamber.

Laundry treating appliance with induction heat

A laundry treating appliance and a method operating a laundry treating appliance having a dye sensor configured to output a signal indicative of the amount of dye within liquid in the treating chamber, a controller having a memory in which is stored a set of executable instructions including at least one user-selectable cycle of operation, and a user interface operably coupled with the controller and providing an input and output function for the controller and provide information related to a dye release.

Laundry treating appliance and method of operation for a laundry treating appliance

A laundry treating appliance comprising a combination washer/dryer having a cabinet defining an interior, a tub provided within the interior, and a drum rotatably provided within the tub and defining a treating chamber, and a method of operation which includes a washing cycle, a spinning cycle and a drying cycle.

A laundry appliance includes a blower that directs process air along an airflow path. A condensing heat exchanger heats the process air to define heated process air. A drum receives the heated process air to dry laundry. A pump directs fluid along a fluid path. An evaporating heat exchanger cools the fluid to define a cooled fluid. A refrigerant circuit directs a refrigerant between the condensing and evaporating heat exchangers. A shower area in which the cooled fluid is showered through the heated process air after the heated process air exits the drum to wash particulate matter out of the heated process air. The pump directs the fluid towards the evaporating heat exchanger in order to cool the fluid, and directs the cooled fluid to the shower area.

Filterless air-handling system for a heat pump laundry appliance

A washing machine comprises a drum and a heat pump system for heating water to be fed to the drum in a washing program. The heat pump system has an evaporator in heat exchange relationship with a room air flow and a condenser in heat exchange relationship with water to be heated, an air deflector being configured to divert said room air flow downstream the evaporator away from the condenser in a water heating configuration and to convey said air towards the condenser in a room air dehumidifying configuration of the washing machine.

Washing machine with heat pump system

A washing machine comprises a tub in which a drum is rotatably mounted, and a storage tank having a flow connection to the tub via a feeding line provided with a pump and a three-port valve adapted to drive the flow to the drain or to the storage tank, rinsing fluid being stored in the storage tank for subsequent reuse. The washing machine further comprises a return pipe connecting the storage tank to the tub by means of a two-port valve, on such return line an auxiliary pump being placed and being used either for emptying the storage tank or for carrying out a spray washing.

Washing machine with a storage tank for reusing water and method for carrying out a water reuse step

A washing machine comprises a tub in which a drum is rotatably mounted, and a storage tank having a flow connection to the tub via a feeding line provided with a discharge pump and a three-port valve adapted to drive the flow to a drain or to the storage tank, rinsing fluid being stored in the storage tank for subsequent reuse. The washing machine further comprises an automatic valve connected to a drain line downstream the three-port valve and to an overflow line downstream the storage tank, said automatic valve being provided with means for avoiding any mixture of flows in the different configurations of the washing machine cycles.

Washing machine with water storage tank

A device for controlling the refrigeration and humidity inside a drawer movable within a compartment of a refrigerator, the drawer being insertable into the forced-air compartment provided in a cabinet of the refrigerator, the compartment receiving cold air forced through a feed conduit provided in the cabinet. The conduit is divided into a plurality of channels, one opening into a side wall of the compartment, and at least one other opening at an upper wall of the compartment above the drawer, in the channels an interceptor member is provided to allow control of the air flow passing through it and directed to the compartment for the drawer.
