Method for controlling water feeding dissolution of washing powder in washing machine and washing machine thereof

Abstract

The invention discloses a method for controlling water feeding dissolution of washing powder in a washing machine and a washing machine thereof. The washing machine comprises a water feeding valve, a water storage box and a washing powder box, wherein the water storage box is arranged between the water feeding valve and the washing powder box and is communicated with the washing powder box; when the washing powder is dissolved, water is firstly fed into the water storage box to reach a set water level, the water is heated to a set heating temperature after the water feeding temperature is detected, a fixed amount of water is continuously fed according to the relationship of the amount of the heated water in the water storage box, the set heating temperature and the water feeding temperature so that the heated water and the fed water in the water storage box are mixed to generate mixed water with the temperature, suitable for the dissolution of the washing powder; the mixed water simultaneously flows into the washing powder box to dissolve the washing powder sufficiently, washing articles are then uniformly soaked in the washing powder-dissolved water in the manner of internally circulated sprinkling and stirring; and finally, the water is fed to reach the set water level for the purpose of washing, therefore, the cleaning rate and the uniformity of the washing articles are improved.

Description

technical field [0001] The invention relates to a washing machine, in particular to a water inlet method capable of controlling the inlet water temperature to achieve the optimum temperature for dissolving washing powder and a device for realizing it. Background technique [0002] The water inlet control method of the current pulsator washing machine mostly adopts the method of directly entering the water from the water inlet valve to the set water level. Although this method is simple, it does not dissolve the washing powder very thoroughly, especially for laundry that has not been completely dissolved. Most of the powder may be washed directly to the bottom of the bucket or only to part of the clothes, which is not conducive to the improvement of the washing rate and washing uniformity of the clothes. There is also a foam generating device that can promote the dissolution of washing powder to dissolve the washing powder, but this device does not help much for the lower tem...

AI Technical Summary

Problems solved by technology

[0007] However, the above-mentioned structure has the following problems. First, two water inlet valves are used, which is costly and complicated to assemble; secondly, the water temperature cannot be controlled, and the mixed water temperature cannot be guaranteed to reach the optimum temperature suitable for dissolving washing powder.
