The present disclosure relates to a heat pump based dryer or a combination washer and dryer device comprising a housing receiving a drum for containing associated articles to be dried by air that flows along a pathway between an outlet and an inlet of the housing. A fluid is provided in the pathway to at least partially remove moisture from the air. A heat pump includes a heat source located at least partially within the pathway and a heat sink being operatively adapted to the heat source to circulate a refrigerant therein. An enclosure at least partially containing the heat sink is arranged to accept the fluid from the pathway to exchange heat with the heat sink and return the fluid to the pathway. Fluid may be provided to the pathway by a spray nozzle adjacent the outlet or by an evaporative media downstream of a lint separator.

The system body (30) receives the source water (16) from the water source (14). The ozone generator (38) is configured to generate ozone. The ozone generator (38) is coupled the system body (30). The sensor assembly (21) is also coupled to the system body (30). The sensor assembly (21) is configured to sense at least one ambient environmental condition and generate at least one electronic data signal based on the sensed at least one ambient environmental condition. The controller (46) receives the at least one electronic data signal from the sensor assembly (21) and regulates a level of ozone that is generated by the ozone generator (38) based at least in part on the at least one electronic data signal.

A clothes treating apparatus including a cabinet having a laundry inlet; a door configured to open and close the laundry inlet; a drum inside the cabinet to accommodate clothes received in the drum through the laundry inlet while the laundry inlet is opened by the door; a sensing device including a sensor to measure a temperature or a humidity in the drum; and a holder on the door or the drum. The sensing device is separably mountable to the holder so that, when the sensing device is mounted to the holder, the sensing device is held by the holder and, when the sensing device is separated from the holder, the sensing device is allowed to move with respect to the drum, within the drum, so as to measure the temperature or the humidity in the drum while clothes accommodated in the drum are being treated.

A dryer comprises: a cabinet; a drum rotatable inside the cabinet; and a hot air supply device for supplying the inside of the drum with hot air. The drum includes: a rear plate to be arranged on the rear side of the drum, the rear plate including a hot air supply hole through which hot air flows toward the drum; and a hot air supply rod protruding along a direction toward the front of the drum and through which the hot air from the hot air supply hole flows toward the drum, the hot air supply rod includes: a humidity sensor to be arranged on the front of the hot air supply rod to measure the humidity of object to be dried; and a self-generation device to generate power as a magnet rotatable with the drum rotates, to supply power generated to the humidity sensor.

A domestic clothes dryer comprises a rotating drum defining a drying chamber, an air inlet upstream the drum and at least a hollow lifter mounted in the drum, wherein said hollow lifter is in communication with the air inlet for distributing air inside the drum through a plurality of openings. The air inlet comprises a shaped air plenum chamber facing a lower portion of a rear perforated wall of the drum and capable of delivering air to said lifter and/or directly to the drum through said rear perforated wall.

A clothes treating apparatus is provided that may include an accommodation chamber, in which an object may be accommodated; a first heat pump cycle having a first evaporator, a first compressor, a first condenser, and a first expansion valve; a second heat pump cycle having a second evaporator, a second compressor, a second condenser, and a second expansion valve, and arranged such that air introduced into the accommodation chamber passes through the first evaporator, the second evaporator, the second condenser and the first condenser, sequentially; and a controller configured to control an operation of the first and second heat pump cycles. At least one of the first compressor or the second compressor may be provided with an inverter that changes a drive speed of the compressor through a frequency conversion. The controller may drive the at least one of the first compressor or the second compressor within a predetermined drive range, by controlling the drive speed of the at least one of the first compressor or the second compressor using the inverter.

The invention provides an apparatus (8) for cleaning cloth which includes a body (10) with an aperture, a closure, which is engageable with the aperture, a tub (26) with an outer shell and a cylindrical Inner cavity which corresponds with the aperture, a drum (28), which is positioned inside the cylindrical inner cavity (54) and which includes a wall, with an inner surface, an outer surface and a plurality of perforations (62) in the wait, a base (64) and an opposing mouth (66) which registers with the aperture, a drive means (30) which is connected to or engaged with the drum and which allows rotational movement of the drum about an axis, a generator (32) and an electrical power supply (78), inside the body, wherein the power supply is adapted to provide pulsating electrical power to the generator and wherein the generator is actuable to produce pulses of microwave energy at least into part of the drum.

A method is provided for controlling a laundry treating apparatus. The method may include controlling the drum to accelerate the drum to rotate at a first speed, applying a brake to stop the drum, accelerating the drum to a second speed, sensing a current being applied to the motor while the drum is accelerated to the second speed, and determining a laundry amount based on the sensed current.

A system in which the operation of an electric motor is controlled by electronically controlled switches. The system includes the motor having a run winding and a start winding, a heating component, and a motor control subsystem. A control unit closes a first switch to energize the run winding, closes a second switch to energize the start winding, determines based on an amplitude and a lag time of a current flowing through the motor whether the motor has started and is running normally, and if so, opens the second switch to de-energize the start winding and closes a third switch to activate the heating component. The control unit determines whether the motor has started and is running normally by comparing the real time amplitude and lag time of the current to a plurality of stored amplitudes and lag times associated with different operating conditions.
