Washing method and washing machine automatically adding washing agent

Abstract

The invention discloses and specifically relates to a washing method and a washing machine automatically adding a washing agent; the washing machine comprises a water inlet valve, a washing agent automatic input system and a washing tub; a water inlet path with a venturi tube is arranged between the water inlet valve and the washing tub; when water flows into the washing machine, a negative pressure zone can be formed in the venturi tube throat under the venturi effect principle; the negative pressure zone is connected in a constant volume valve so as to form negative pressure in the constant volume valve, thus drawing the washing agent in a washing machine distributor connected with the constant volume valve to a constant volume unit; then water enters the constant volume valve through a negative pressure channel of the venturi tube, and flushes the washing agent from the constant volume valve to the washing tub. The washing method and machine can effectively solve the problems that an existing washing agent automatic adding device is complex in structure, poor in automatic input precision, and long in water inflow time.

Description

Technical field [0001] The invention belongs to the field of household appliances, and relates to a washing method with automatic addition of detergents. The invention also relates to a washing machine to which the washing method is applied. Background technique [0002] When traditional washing machine uses detergent, it needs to be added to the corresponding position of the water storage tank before each wash, which is more annoying, and the amount of detergent added each time is variable, which cannot meet the actual adding demand. Moreover, with the development of technology and changes in user concepts, the use of detergents has become more and more common, and more and more washing machine manufacturers have introduced washing machines with automatic detergent addition, which is a trend. [0003] At present, there have been technical disclosures about automatic detergent addition, such as the invention patent No. CN 102086586, which discloses a washing method and a washing ma...
