Dish-washing machine water saving method and dish-washing machine

Abstract

The invention relates to the technical field of household electrical appliances, and especially relates to a dish-washing machine water saving method, comprising a water softening apparatus. The water softening apparatus comprises a salt chamber used to store saturated salt water, and a resin chamber used to store resin. A pipe communicates the salt water and the resin chamber. The pipe is provided with a one-way valve. The method is characterized in that through comparing accumulated water inflow Q1 entering the resin chamber with a regeneration rated value Q set by the water softening apparatus, whether to control the water softening apparatus to perform regeneration operation or not is determined according to a comparison result. Also disclosed is a dish-washing machine which uses the dish-washing machine water saving method. Regeneration after a washing process each time of a conventional dish-washing machine is changed into an independent regeneration program module, and when water inflow of the dish-washing machine reaches the rated value of the water softening apparatus, the regeneration is performed, so as to achieve an objective of reducing water consumption of the dish-washing machine.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a water-saving method for a dishwasher and the dishwasher. Background technique [0002] At present, a water softening device has been introduced in the field of dishwashers. The resin in the water softener absorbs calcium and magnesium ions in the water body to reduce the hardness of the water, ensure soft water for washing dishes, and reduce the formation of scale. A water softener is usually composed of a salt chamber and a resin chamber, and the conduction and isolation of the two chambers are controlled by a solenoid valve. [0003] The regeneration process of the water softener is: after the resin in the water softener replaces the calcium and magnesium ions in the water, the calcium and magnesium ions are adsorbed in the resin and gradually reach saturation. The solenoid valve connected to the resin chamber is opened, and the NaCl solution in the salt chamber...

AI Technical Summary

Problems solved by technology

[0004] The existing technology sets the regeneration action of the water softener in the program, such as figure 1 (The flow chart of the existing washing program) shows that the regeneration of the water softener must be performed before the end of each washing program, and the regeneration of the water softener is performed in the final stage of rinsing, such as figure 2 Shown is the timing diagram of the existing washing program, the water consumption for each regeneration is about 1-2L, which makes the water consumption of the whole machine relatively high
