Embodiment 1

[0313] A control method of a laundry device, wherein the laundry device is configured to heat a drum containing laundry through an induction heater installed in an outer tub, wherein the control method includes:

[0314] a water supply step of supplying washing water containing detergent into the drum;

[0315] a step of wetting the laundry with washing water after the water supplying step; and

[0316] The heating step of repeatedly supplying the water in the lower part of the outer tub to the laundry inside the drum by using a circulation pump after the step of soaking the clothes, and driving the induction heater while rotating the drum to pass through the drum to heat the wash water and laundry.

Embodiment 2

[0318] In the control method of the washing machine described in Embodiment 1, it is characterized in that,

[0319] In the heating step, the drum rotates by repeating acceleration and deceleration, preferably periodically.

Embodiment 3

[0321] In the control method of the washing machine described in Embodiment 1, it is characterized in that,

Abstract

The present invention relates to a washing apparatus and, more particularly, to a washing apparatus which heats a drum by an induction heater, and a method for controlling same. One embodiment of thepresent invention may provide a method for controlling a washing apparatus including: a tub; a drum; an induction module mounted on the tub and heating the drum by induction; and a circulation pump for pumping washing water in the tub to supply the washing water to an upper portion of the drum, the method comprising: a water supply step of supplying washing water into a tub through a water supplyvalve; a laundry soaking step of, after finishing the water supply step, operating a circulation pump to circulate the washing water and driving a drum to perform laundry soaking; a heating step of driving an induction module to perform heating after finishing the laundry soaking step; and a main washing step of driving the drum to perform washing after finishing the heating step, wherein a washing water level at the end of the laundry soaking step is lower than a washing water level at the end of the water supply step.

Description

technical field [0001] The present invention relates to a laundry device, and more particularly, to a laundry device that heats a drum using an induction heater and a control method thereof. Background technique [0002] The laundry machine includes an outer tub (outer tank) storing washing water and a drum (inner tank) rotatably provided in the outer tub. The drum has laundry (clothes) inside, and the laundry is washed with detergent and washing water as the drum rotates. [0003] In order to increase the washing effect by promoting the activation of detergent and the decomposition of pollutants, high-temperature wash water is supplied to or heated inside the tub. For this reason, generally, a heater installation part is formed in a downward recess on the lower part inside the outer tub, and the heater is disposed on the heater installation part. Such heaters are typically sheath heaters. [0004] When washing with cold water, the heater is not driven. However, in norma...
