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 for operating a clothes treating apparatus comprising a hot air supplying unit provided with a heater and a blowing device, and having a drying function of drying clothes by supplying hot air into a drum by use of the hot air supplying unit, includes rotating the drum with the clothes introduced therein, and supplying hot air into the drum by using the heater and the blowing device while the drum is rotated, wherein an air flow rate supplied by the blowing device changes during the hot air supplying step.

A multiple laundry treating machine, in which an auxiliary laundry treating device is coupled to a general laundry treating device, is disclosed. The multiple laundry treating machine includes a main laundry treating device for washing or drying laundry contained in an interior of the main laundry treating device, an auxiliary laundry treating device arranged at one side of the main laundry treating device, the auxiliary laundry treating device having a volume and a height respectively smaller than a volume and a height of the main laundry treating device, and having a laundry container formed in an interior of the auxiliary laundry treating device, and a connecting unit for connecting the main and auxiliary laundry treating devices, to enable communication or control operations between the main and auxiliary laundry treating devices. In accordance with the multiple laundry treating machine, it is possible to achieve a convenience in use and to save energy because a small amount of clothes or shoes can be dried by the auxiliary laundry treating device, without driving a laundry treating device having a relatively-large capacity.

A method for controlling an exhaust type clothes dryer may include measuring humidity of air passing through an interior of the drum to sense a degree of dryness of a target item, and discharging air that has passed through the drum or recirculating at least a portion of air that has passed through the drum to the drum by comparing a degree of dryness of the target item with a predetermined reference value. In the recirculating of air, an amount of recirculated air may be increased according to an increase in the degree of dryness of the target item by adjusting a degree of opening of a recirculation channel.

Provided are a clothes dryer using far-infrared heating and a clothes-drying control method thereof. The clothes dryer using far-infrared heating includes a clothes-drying drum, and further includes at least one far-infrared heater, a humidity sensor for detecting exhaust humidity of the clothes-drying drum, a relay and a controller having an output end connected with the relay; where all the far-infrared heaters are connected with a power supply through the relay; a first temperature sensor is mounted inside one of the far-infrared heaters; the first temperature sensor and the humidity sensor are connected with an input end of the controller; and the controller controls on and off of the relay according to a received temperature signal or humidity signal. A control system described above simplifies a circuit, and also saves cost.

A washing machine includes: a tub; a drum of metal material configured to be rotated in the tub; an induction heater configured to be fixed to the tub in a state of being separated from the drum, and to heat the drum; a first temperature sensor configured to have a tube of metal material heated by the induction heater and a thermistor disposed in the tube, at least a part of the tube being exposed between the tub and the drum; a second temperature sensor configured to be disposed in a position further away than the first temperature sensor from the induction heater in a circumferential direction, and detect a temperature of air between the tub and the drum; and a controller configured to control the induction heater based on a first detection value of the first temperature sensor and a second detection value of the second temperature sensor.

A clothes dryer comprises an inner drum, an outer drum, an air heating and supplying means and an air duct, and at least two air chambers each in communication with the air duct. The air chambers are respectively arranged corresponding to two sides along which clothes rise or fall as the inner drum rotates, the air chamber at one side starts supplying air and the air chamber at the other side stops supplying air according to a rotation direction of the inner drum, all air chambers are distributed in the order of front and rear of the outer drum in an axial direction, and the rotation direction of the inner drum is controlled according to the distribution of the air chambers, such that air is supplied in different positions corresponding to the front part and the rear part of the inner drum at different clothes drying stages, in order to dry clothes.
