Embodiment Construction
[0019] The structure of the present invention has been described above, and the use of this instrument is such that at first two water storage bottles are filled with equal amounts of water, and the power supply (such as Figure II As shown), at this time, the switching power supply a starts to work to provide power for the temperature control resistor b and the cooling sheet c, and the cooling sheet starts to work to cool the outlet pipe 2 close to its cooling side, and to cool the outlet pipe 2 close to its heat dissipation surface 2 heating. The temperature control resistor is installed at 8 hot water ends of the water outlet pipe to feel the water temperature of the pipe, so when the preset temperature reaches 40°C, an instruction is sent to the cooling plate to stop working, and when the water temperature in the pipe drops to less than 40°C ℃, then re-instruct it to start working, and now the water temperature of the other outlet pipe can be kept at about 4 ℃.
