Description

Embodiments of the present invention relate to a garment processing apparatus. Conventionally, washing machines are known to use a foam sensor to detect foam leakage (foam leaking out of the water tank) or the generation of more than a certain amount of foam that could affect the finish of the clothes during the washing or spinning cycle, and then perform actions to remove the foam from the water tank and clothes. For example, Patent Document 1 discloses a drum-type washing machine in which an outer tub is supported within a frame, a horizontal-axis type washing drum having numerous perforations around its periphery is rotatably supported within the outer tub, and the washing drum is rotated by a rotational drive means to wash the laundry placed inside the drum. The washing machine comprises a means for supplying water to the outer tub, a means for discharging liquid from the outer tub, a control means for controlling the operation of each means, and a foam detection means for detecting excessive foaming in the outer tub. The control means is configured to execute foam elimination control consisting of a water supply operation by the water supply means and a drainage operation by the drainage means when a foam detection signal is input from the foam detection means during washing.
