Problems solved by technology
In the related technology, the judgment method of circulating water heater is single and the misjudgment rate is high, and the antifreeze treatment can only be performed when the power is turned on. Once the unit is powered off, the antifreeze protection will not work, which will easily cause water pipes to crack and economic losses.

The invention discloses an anti-freezing pre-warning control method and device for a circulatory water heater. The method comprises steps as follows: detecting a minimum inlet water temperature value of master and slave machines, a minimum outlet water temperature value of the master and slave machines and a minimum environment temperature value of the master and slave machines; judging whether the minimum environment temperature value of the master and slave machines is smaller than a first preset temperature value; judging whether a corresponding anti-freezing warning signal is generated according to the minimum inlet water temperature value and the minimum outlet water temperature value of the master and slave machines if the minimum environment temperature value of the master and slave machines is smaller than the first preset temperature value; warning according to the corresponding anti-freezing warning signal. Accordingly, whether anti-freezing treatment is required can be judged accurately, the misjudgment rate is reduced, a user or an administrator can be informed of anti-freezing treatment in advance, the probability that the circulatory water heater is frozen is reduced, and heavier economic loss is avoided.
Description
technical field [0001] The invention relates to the technical field of water heaters, in particular to an antifreeze early warning control method for a circulating water heater, an antifreeze early warning control device for a circulating water heater, and a circulating water heater system. Background technique [0002] Circulating water heaters mainly provide the function of making hot water. In colder winter areas in the north, the ambient temperature is often below zero. When using water heaters in these areas, the antifreeze requirements for the circulating water system are relatively high. In the related art, the judging method of the circulating water heater is single and the misjudgment rate is high, and the antifreeze treatment can only be performed when the power is turned on. Once the unit is powered off, the antifreeze protection will not work, which will easily cause water pipes to crack and economic losses. Contents of the invention [0003] The present invent...
