Kind Code:

A1

Abstract:

Provided are a drum washing machine and a control method for door opening during washing process. The control method comprises the following steps: S1, receiving a door opening instruction sent by a user; S2, determining whether the water level at a front end of a barrel assembly (1) of the washing machine meets a door-opening condition, if the door-opening condition is met, then proceeding to step S4, otherwise, proceeding to step S3; S3, using a tilting mechanism to tilt the barrel assembly (1), and then returning to step S2; S4, unlocking the door. By raising the front end of the barrel assembly (1), the door opening operation during the washing process can be realized, thereby original parts of the washing machine do not need to be changed, and the barrel assembly (1) can be tilted only by means of a drive device (2) disposed on a lower part of the barrel assembly (1) or a hanged spring (3) disposed at the top of the barrel assembly (1), without affecting the appearance of the washing machine and without the need to consider the sealing problem during the washing process. In addition, the user can open the door during the washing process to put in or take out laundry, add detergent, or deal with the fading of the clothes without causing waste of water resources.
