Title:
VALVE CORE STRUCTURE OF SEAL VALVE AND NO-CLEAN WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/165924
Kind Code:
A1
Abstract:
The present invention relates to a valve core structure of a seal valve, comprising a valve plunger correspondingly provided at a drainage port formed on the sidewall of an inner tub, and a balancing weight hingedly connected to the upper end of the valve plunger. A seal valve mounting structure is fixedly mounted on the sidewall of the inner tub. A reset spring is clamped between the seal valve mounting structure and the valve plunger. By mounting the valve core structure on the inner tub, the balancing weight can open the drainage port under the centrifugal force, and the valve plunger can be reset by means of the reset spring, and the valve core correspondingly blocks the drainage port, so that the drainage port is open/closed by means of the valve plunger under the centrifugal force produced by high-speed rotation of the inner tub. Also provided is a no-clean washing machine. An inner tub of the washing machine is a container that is sealed after an opening is closed by a cover. At least one lifting rib is provided on the sidewall of the inner tub. A drainage port communicated with a hollow portion of the lifting rib is provided on the sidewall of the inner tub. A seal valve inside the lifting rib is provided at the drainage port. The seal valve has the valve core structure.
