Refrigeration control method and device for household water machine

Abstract

The invention discloses a household water machine refrigeration control method and device. The method includes the following steps that S1, a refrigeration command is received, and a refrigeration model is enabled according to the refrigeration command; S2, operation parameters of a household water machine are obtained; S3, whether the pause condition is met or not is judged according to the operation parameters; S4, if the pause condition is met, refrigeration is paused; S5, whether a restart condition is met or not is further judged, if the restart condition is met, refrigeration is conducted, and the S2 to S5 are executed repeatedly till the refrigeration end condition is met. Accordingly, in the operating process of the household water machine, the performance of a condenser and an evaporator can be restored to be the optimal performance state through refrigeration pause, and the evaporating temperature can be lowered to a low degree in next operation, so that the performance of the condenser, the evaporator and a compressor can be multiplied, super-low water temperature refrigeration is achieved, the refrigeration capacity is improved, and the stability of the household water machine is improved.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a refrigeration control method for a household water machine and a refrigeration control device for a household water machine. Background technique [0002] For the drinking water equipment industry, due to the limitation of industry cost factors, the cooling capacity of related drinking water equipment is generally designed at about 2 liters. If the cooling capacity is further increased, the cost of drinking water equipment will increase significantly, thus losing price competitiveness. . [0003] The following shortcoming mainly exists in related technology: [0004] One is that the condensers of related drinking water equipment cannot meet the performance requirements of ultra-low water temperature. This is because after the condenser rises to a certain temperature, the evaporation temperature in the drinking water equipment will no longer change, and the refri...

AI Technical Summary

Problems solved by technology

If the compressor is replaced with a compressor with a larger displacement, it will lead to an increase in product cost

Moreover, in order to match with the compressor, the corresponding evaporator should be made very large and the capillary tube should be made very long, which will also increase the cost

[0006] Therefore, improving the refrigeration capacity of drinking water equipment by increasing the displacement of the compressor, increasing the size of the condenser and evaporator, and increasing the capillary will greatly increase the production cost, making it difficult for users to accept, and reducing the market competitiveness of the product.
