Be T0 to the water temperature in constant temperature water tank, specifically, for by the way of electrically heated rod, in constant temperature water tank water trunkful but
In the case that water temperature is still excessively high, then continue to inject cold water into constant temperature water tank by cold water pipe so that the heat in constant temperature water tank
Water is reversely delivered in main water box 1, to realize the water temperature reduced in constant temperature water tank.And it is auxiliary for being carried out using semiconductor chilling plate
Under conditions of helping heating to freeze, water is after trunkful in constant temperature water tank, if T<T0, then electric calorifie installation is in constant temperature water tank
Water carries out heating until water temperature is T0；If T>T0, then electric calorifie installation to the water in constant temperature water tank carry out refrigeration until water temperature be
T0.Preferably, it during constant temperature water tank adjusts water temperature, can be stirred by electric mixer equal to accelerate distribution of water temperature
It is even.
Further, further include leak water detdction pattern, the leak water detdction pattern includes：First water level sensor detects
When to water level decreasing, if water flow is not detected in the 4th flow sensor, it is determined as main water box leak；First level sensor
When device detects that water level decreasing and the 4th flow sensor detect water flow, if flow is not detected in first flow sensor
Amount, then be determined as main water box leak.
