With the rapid development of smart home appliances, many products pay more attention to the convenience of people and the health and safety of life from a people-oriented perspective. Such as electric hot water faucets, water cups, etc., it can display and control temperature, and it can also avoid accidental injury and use it safely. Thermal protectors are important electronic components that make this function possible. There are two types of electric hot water faucets: 1. The spiral heating body is heated in the water tank, 2. The heating body is die-casting, and a leakage protector is connected to the heating power line. The overheating protection device adopts one of the following two: The first Yes: when the 1 form is adopted, a thermal protection cavity sleeve is arranged beside the spiral heating body in the water tank, a normally open temperature switch is installed in the thermal protection cavity sleeve, and the normally open temperature switch is connected to the leakage protector; using 2 In the form, the normally open temperature switch is fixed on the surface of the die-casting heating body; the second is: a temperature measuring probe is set in the electric hot water faucet. The temperature probe is located on the water outlet pipe, and a single chip microcomputer is also arranged in the electric hot water faucet. The protection principle is: the thermal protector detects the temperature of the heating body and judges whether it is at a safe temperature. If it exceeds the set temperature, it can control the circuit on and off, thereby protecting the safe use of the electric hot water faucet.
The outstanding advantages of using a mechanical thermal protector for temperature measurement are very high sensitivity, high measurement accuracy, good consistency and low price. Moreover, since the size of the thermal protection can be made very small, it is especially suitable to be placed in a small space in the installation environment.
