Problems solved by technology

However, according to the output of the induction heating system, the temperature change of the drum is sensitive, but the change of the water temperature or the temperature of the air is slow, so there is a possibility that the value detected by the thermal sensor cannot accurately reflect the temperature of the drum. temperature change problem

Abstract

A washing machine includes: a tub configured to contain water; 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 heaterin 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 firsttemperature sensor and a second detection value of the second temperature sensor.

Description

technical field [0001] The present invention relates to a washing machine provided with an induction heater and a control method thereof. Background technique [0002] Generally, a washing machine is configured such that a drum for accommodating laundry is rotatably disposed in an outer tub providing a space for storing water. A through hole is formed in the drum so that the water in the tub flows into the drum, and the laundry swims by the rotation of the drum, and at the same time, stains of the laundry are removed. [0003] Such a washing machine may also be provided with a heater for heating water in the tub. Usually, the heater operates under the condition that water is stored in the outer tub, and directly heats the water. However, this method requires the heater to operate in a state where water is stored all the time due to safety reasons, although the heater can be used to heat the water in the outer tub, but in the outer tub In the absence of water, it is not su...
