Abstract

A drum washing machine and a control method for opening a door of the drum washing machine during running are provided. The control method comprises the following steps: S, receiving a door opening instruction sent by a user; S, judging whether a water level at a front end of a drum assembly of the drum washing machine satisfies a condition of opening the door, if yes, entering step S, if no, entering step S; S, tilting the drum assembly with a tilting mechanism, and then returning to step S; and S, unlocking a door lock. Through a manner of lifting a front end of the drum assembly, the operation of opening the door during running is realized. In this way, the original parts of the washing machine do not need to be changed.
