Abstract:
A washing machine door lock module and a control method for a washing machine. The washing machine door lock module (5) comprises: a positioning lock (3) in which a positioning rod (33) and a door opening rod (32) are arranged, wherein the positioning lock (3) has a positioning stroke and an unlocking stroke, and in the unlocking stroke, the positioning rod (33) extends out, and the door opening rod (32) is driven by the positioning rod (33) to extend out of the positioning lock (3) and generate an unlocking action that triggers the unlocking of a door lock (5); and a detection device, used for detecting the extension position of the door opening rod (32), and detecting whether the door opening rod (32) completes the unlocking action. By detecting the extension position of the door opening rod (32) by means of the detection device, the unlocking condition of the door lock (5) is detected, and the unlocking accuracy of the door lock (5) is improved. The control method for the washing machine comprises: when a washing tub door (2) is opened and after the positioning lock (3) completes the positioning stroke, the positioning rod (33) extends out, and the door opening rod (32) is driven by the positioning rod (33) to extend out of the positioning lock (3) to a first extension position, and generate the unlocking action that triggers the unlocking of the door lock (5); and if the door opening rod (32) is at the first extension position, the door opening rod (32) completes the unlocking action.
