A laundry treatment apparatus is configured to directly heat a drum containing laundry therein. The laundry treatment apparatus includes: a tub; a drum configured to rotate within the tub and to contain laundry therein, the drum being formed of a metallic material; and an induction module provided at an outer surface of the tub and configured to heat a surface of the drum within the tub via induction, the induction module comprising: a coil that comprises a wire through which an electric current is configured to pass so as to generate a magnetic field; a base housing configured to accommodate the coil therein, the base housing being mounted on the outer surface of the tub; an at least one magnet configured to be arranged above the base housing in which the coil is accommodated, and arranged to be lengthwise perpendicular to a longitudinal direction of the wire of the coil.

HEATING CONTROL SYSTEM OF MULTI-DRUM WASHING MACHINE

A multi-drum washing machine comprises at least two sets of heating devices, and at least two detection units which are correspondingly connected with the heating devices. Each detection unit is used for detecting heating information of the corresponding heating device and controlling at least one other heating device to be turned on/off according to the heating information. The heating control system of the multi-drum washing machine solves the problem that it is difficult to detect heating devices in a multi-drum washing machine, thus increasing the calculation burden of a processor. The disclosure realizes real-time detection of the heating devices through simple detection circuit hardware connection on a circuit of each heating device. The circuits are detected by using connection structures of circuit hardware, thereby saving cost, improving the sensitivity of the detection circuits and prolonging the service life of the processor of the multi-drum washing machine.

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.

Tumble dryer and method for drying laundry using a tumble dryer

A tumble dryer has a drum for laundry, a drive motor for the drum, an air supply to the drum and an air discharge from the drum, a fan, including a fan drive, for generating an air stream to the drum through the air supply and away from the drum through the air discharge, and also heating means for heating the air stream. The temperature of and the moisture in the air which is discharged from the drum are detected. The profile of said temperature and moisture is compared with prespecification curves, which are stored in a memory, for the profile of said temperature and moisture by means of calculation means depending on the drying phase of the laundry. The operating point of the prespecification curve at which the drying program is located is determined in this way. The control arrangement influences the further drying program, on the basis of the operating point, by way of adjusting the temperature and/or the intensity of the air stream.

Clothes dryer fire reduction system

A clothes dryer apparatus and system that reduces the buildup of electric charges within a dryer drum by introducing ions. The system monitors the voltage within the drum by taking measurements on voltage sensor assembly. The sensor assembly obtains a voltage when two areas of a fabric, or two separate items of the clothing, contact the sensor. If a threshold voltage is obtained, an ion generator introduces cations and anions into the drum of the dryer to neutralize the static charge of the clothing. The reduction of static electricity increases efficiency as the clothing items do not stick together which permits better heat flow and increases safety by reducing the amount of electrical charge within the drum.

TEMPERATURE CONTROL METHOD FOR CLOTHES DRYING TREATMENT DEVICE, AND CLOTHES DRYING TREATMENT DEVICE

A heating device of a clothes drying treatment device executes an on or off operation in a temperature interval. When the temperature in a drum reaches an upper limit value TDx of the temperature interval under an action of the heating device, the heating device is turned off and the heating device stops heating. The upper limit value TDx decreases as a number of off times x of the heating device increases. Accordingly, a higher initial off temperature is adopted for the heating device, the temperature in the drum rapidly increases to the drying temperature, a preheating time is shortened, and a certain coefficient is multiplied in following control parameters controlling on or off of the heating device. The coefficient is related to the number of on-off times, and the effect is achieved that the off temperature of the clothes dryer gradually decreases as the number of on-off times increases.
