Water supply system of cleaning machine

Abstract

The invention provides a water supply system of a cleaning machine. The water supply system of the cleaning machine is characterized by comprising a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a fourth electromagnetic valve, a fifth electromagnetic valve, a TDS sensor, a first electro-desalting module, a second electro-desalting module, a water purifying module and a control module. Compared with the prior art, the water supply system of the cleaning machine has the advantages that two different water treatment paths are provided for selection, no matter which water treatment path is selected, cleaning water obtained after treatment is softened water, namely tap water always needs to pass by positive and negative electrode sheets in the electro-desalting modules for desalting, in the manner that under the action of an electric field, positive ions in the tap water migrate to the negative pole, negative ions in the tap water migrate to thepositive pole, the purpose of removing ions in the tap water is achieved, and additionally introducing new ions is not needed.

Description

technical field [0001] The invention relates to a water supply system of a washing machine. Background technique [0002] There are two ways of water supply to the existing cleaning machine, one is to directly use ordinary tap water to supply water to the cleaning tank or / and the fruit and vegetable tank, and the other is to use resin to produce softened water to supply water to the cleaning tank or / and fruit and vegetable tank, but due to resin After absorbing calcium and magnesium ions in the water, it will be saturated, and needs to be regenerated by adding salt, and the softened water produced by the resin itself contains a large amount of Na+, resulting in a large amount of Na+ residue after washing dishes, which is not suitable for low-sodium people. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water supply system for a washing machine in view of the above-mentioned prior art, which has high softening ...
