A CONTROL METHOD FOR PREVENTING ELECTRICAL WATER BOILER FROM EMPTY BOILING

摘要

The present application discloses a control method for preventing electrical water boiler from empty boiling, the problem to be solved of which is to judge the temperature rise in container exactly and then cut off power, which include steps as follows: (1) provide a sensor, a microprocessor and a control circuit in the electrical water boiler; (2) the sensor reads real-time temperatures within the container; (3) the microprocessor calculates temperature change rate and compares it with a prescribed value; (4) if the temperature change rate is larger than the prescribed value, the microprocessor sends a message to the control circuit to cut off the power. The control method according to the present application can judge the temperature rise in container exactly and cut off power in time, thus prevent the electrical water boiler from destroying.
