Title:
DOOR LOCK DEVICE AND WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/228173
Kind Code:
A1
Abstract:
A door lock device and a washing machine. The door lock device comprises a lock hook mechanism (3), the lock hook mechanism (3) comprising: a lock seat (33) internally provided with a lock hook shaft (34); and a lock hook member (31) and a limiting member (32), which synchronously rotate around the lock hook shaft (34) to open or lock a door lock, wherein a side wall of the lock seat (33) is provided with a limiting cooperation portion (33111) corresponding to the limiting member (32) and used for limiting the reverse rotation of the lock hook member (31), and the lock hook member (31) cooperates with the limiting member (32) in a transmission manner by means of a reversing transmission component (37); and the reversing transmission component (37) is configured such that a reverse rotation displacement of the lock hook member (31) in a circumferential direction of the lock hook shaft (34) can be converted into an axial displacement whereby the limiting member (32) is pushed to move toward the limiting cooperation portion (33111), so as to make the limiting member (32) clamped and limited on the limiting cooperation portion (33111) to limit the reverse rotation of the lock hook member (31). The door lock device is mounted between an inner drum and an inner drum door, such that serious safety accidents caused by the inner drum door being opened by means of the lock hook member reversely rotating under the action of a centrifugal force due to the high-speed spinning of the inner drum during a washing or dewatering procedure of the washing machine can be effectively avoided.
