Washing machine and control method

Abstract

The invention provides a washing machine and a control method. The washing machine comprises a washing barrel, a water pan and a drainage device; a blocking piece is arranged at a water outlet of the washing barrel; the drainage device comprises a sealing limiting structure, a rod piece and a driving mechanism; the sealing limiting structure forms a cavity and a sealing part; the rod piece is connected with the sealing part and slides up and down under the action of the driving mechanism so as to open or close the water outlet; the drainage device comprises a first support, a fixing part of the sealing limiting structure is fixed to the first support, the driving mechanism comprises an elastic piece, a traction motor and a traction rope, when the traction motor rotates in the forward direction, the rod piece slides downwards, and when the rod piece moves to a first preset position, the water outlet is opened; when the rod piece moves to a second preset position, the sealing part is located below the water outlet; and when the rod piece moves to a third preset position, the sealing part seals the water outlet. The structure is simple, the control process is simplified, sealing is tight, and positioning is accurate; and the problems that an existing drainage device is complex in structure and inaccurate in positioning are solved.

Description

technical field [0001] The present invention relates to the technical field of laundry equipment, in particular to a washing machine and a control method. Background technique [0002] With the development of economy and society, washing machines have gradually become an indispensable household appliance in people's daily life; washing machines with a single-tub structure have gradually attracted widespread attention.
