Title:
AUTOMATIC LIQUID DISPENSING DEVICE FOR WASHING APPARATUS, AND WASHING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/001854
Kind Code:
A1
Abstract:
Disclosed are an automatic liquid dispensing device for a washing apparatus, and a washing apparatus. The automatic liquid dispensing device comprises a driving device and a liquid suction device. The liquid suction device comprises a liquid suction cavity for containing a liquid, and further comprises: a diaphragm that forms part of the side wall of the liquid suction cavity, the diaphragm having elasticity and being capable of changing the air pressure difference between the inside and outside of the liquid suction cavity by means of elastic deformation, so that the liquid suction device suctions and discharges the liquid; and a mover used for applying force to the diaphragm so that the diaphragm produces elastic deformation, the mover being not connected to the diaphragm. The device can drive the mover to repeatedly impact the diaphragm at a certain frequency, so that the diaphragm vibrates and causes an air pressure value relationship between the inside and outside of the liquid suction cavity to change continuously, and thus the objective of dispensing a liquid is achieved by changing the air pressure difference between the inside and outside of the liquid suction cavity. The liquid dispensing device only comprises a mover and a liquid suction cavity, so that the structural parts of the liquid dispensing device are greatly reduced, and the liquid dispensing speed can be increased by increasing the impact frequency of the mover, so that the speed of adding a detergent liquid can be adjusted.
