Problems solved by technology

[0002] At present, water treatment equipment uses compressors or semiconductor refrigeration modules to cool water. Freon is used for compressor refrigeration. This method is not conducive to environmental protection, and the compressor is noisy and energy-consuming.
For semiconductor refrigeration, the amount of cold water discharged at a time is small, the effect is poor, and failures are prone to occur.
In order to ensure that users can use cold water in a timely manner, whether it is semiconductor refrigeration or compressor refrigeration, because the water production speed of the two is slow and cannot immediately produce cold water, it is necessary to set up a water tank to store cold water, and the setting of the water tank makes the equipment Overall volume is large

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to water treatment equipment. Background technique [0002] At present, water treatment equipment realizes cooling water through compressors or semiconductor refrigeration modules, and Freon is used for refrigeration of compressors. This method is not conducive to environmental protection, and the operation noise of compressors is large, and energy consumption is high. For semiconductor refrigeration, the amount of cold water discharged at a time is small, the effect is poor, and failures are prone to occur. In order to ensure that users can use cold water in a timely manner, whether it is semiconductor refrigeration or compressor refrigeration, because the water production speed of the two is slow and cannot immediately produce cold water, it is necessary to set up a water tank to store cold water, and the setting of the water tank makes the equipment The overall volu...
