Abstract

A control method for a wall-mounted drum washing machine, which removes foams remaining in a detergent box and a conditioner box at a final stage of a spin-drying process of the wall-mounted drum washing machine, thereby maintaining the detergent box and the conditioner box in a clean state.

First claim

What is claimed is:

1. A control method for a wall-mounted drum washing machine including a detergent box and a conditioner box which are inserted into a tub through a front panel, the control method comprising:
stopping, by a control unit, control for a motor during a spin-drying process;
determining, by the control unit, whether or not a foam removal condition is satisfied, after the control for the motor is stopped;
opening, by the control unit, a water supply valve for a preset foam removal time in order to remove foams of the detergent box and the conditioner box, when it is determined that the foam removal condition is satisfied; and
stopping, by the control unit, the motor to complete the spin-drying process, after the foam removal time passes, wherein the foam removal condition is satisfied when a preset time passes from the time at which the control for the motor is stopped, wherein the control unit rotates the motor at an RPM at the time at which the preset time passed, for the foam removal time, and
wherein a drum disposed on the tub is not dipped into water supplied from the water supply valve.

2. The control method of claim 1 , wherein the foam removal condition is satisfied when the RPM of the motor reaches a preset reference speed.

3. The control method of claim 2 , wherein the control unit rotates the motor at the reference speed for the foam removal time.
