Abstract

The present invention relates to a door lock (DOOR LOCK) device for opening and closing the washing tank (dehydration tank) of the washing machine and the door lock control method, in the conventional washing machine to wash in a state in which hot water (60 ℃ or more) is supplied to increase the washing rate Especially in the case of the washing machine adopting the boil- ing washing course, the laundry is boiled at a high temperature. When the user opens the washing tank (dehydration tank) by accidental identification or carelessness of the washing situation, the hot water vapor filled in the washing tank is momentarily released. There is a problem with the risk of burns.

The present invention locks the door of the washing tank arbitrarily when the burn temperature is higher than the burn temperature in the water supply step of hot water, and releases the door lock after the washing, rinsing and dehydration in this state, and in the case of the washing course, the washing tank door is locked first By heating the heater to boil the laundry and then re-water supply to lower the water temperature and release the door lock to eliminate the risk of burns caused by high temperature water vapor, thereby improving the safety of the washing machine. Applies to the control unit.
