Inner container positioning lock of impeller type washing machine

Abstract

The present invention discloses an inner container positioning lock of an impeller type washing machine. The inner container positioning lock comprises a lock post, a sealing device and a drive device, wherein the sealing device comprises a disc-type pedestal, a sleeve and a sealing rubber, the sleeve is fixed on an outer side face of the disc-type pedestal through screws, one end of the sealing rubber is placed inside the sleeve and pressed between the sleeve and the disc-type pedestal while the other end is folded and sleeves the other end of the sleeve, the lock post penetrates through the sleeve and the disc-type pedestal in turn and is connected with the drive device through a connection rod, a sealed receiving cavity is formed among the other end of the sealing rubber, the lock post and the disc-type pedestal, the lock post is sleeved by the spring which is pressed into the receiving cavity, and the drive device drives the lock post to stretch out of or retract into an inner container locking hole of a washing machine, thus to realize locking or operating of the inner container of the washing machine. According to the inner container positioning lock provided by the present invention, in an operating process of the inner container of the washing machine, the drive device drives the lock post to stretch out of or retract into the locking hole of the inner container of the washing machine, thus to realize locking or operating of the inner container of the washing machine, thereby realizing accurate positioning of a drainage port of the inner container.
