Application of thermal protector in range hood motor

As people's living standards improve, range hoods in kitchens have become essential home appliances. However, range hoods generate high temperatures when working, which can easily cause safety hazards. Therefore, how to effectively protect the safety of users has become an important issue. Bimetallic thermal protectors, as an effective protective device, are widely used in range hoods.

The application of thermal protectors in range hood motors is to prevent electrical equipment from overheating, thereby protecting the safety of the equipment and users. Thermal protectors come in various shapes and sizes and can be used in a variety of electrical appliances, including range hoods and microwave ovens, motors, motors, water pumps, etc. They require heaters of various types and sizes, and if the electrical equipment overheats, the thermal protector can immediately cut off the power supply, thereby protecting the safety of the equipment and users.

The bimetallic thermal protector is composed of a bimetallic strip, a heating element, a thermostat and a power supply. When the range hood is working, the temperature will continue to rise. When it exceeds the set temperature, the bimetallic strip will automatically disconnect the power supply, thus avoiding accidents such as fire.

The performance parameters of bimetal thermal protectors include temperature range, response time, recovery time, overload capacity, etc. Among them, the temperature range refers to the highest temperature that the bimetal can withstand; the response time refers to the speed at which the thermal protector responds to temperature changes; the recovery time refers to the time it takes for the bimetal to reconnect the power supply after the power supply is disconnected; and the overload capacity refers to the maximum current that the bimetal can withstand.

The application scenarios of bimetallic thermal protectors in range hoods mainly include the following aspects:

Overheating protection caused by the range hood's own fault. When the range hood fails, it may overheat, triggering the thermal protector to disconnect the power supply.

Overheat protection caused by power short circuit. When the internal circuit of the range hood is short-circuited, the thermal protector will be triggered to disconnect the power supply.

Overheat protection caused by excessive air volume of the range hood. When the range hood is running, it will generate high-speed airflow, which will cause the overheat protector to disconnect the power supply.

Overheat protection caused by over-temperature of the range hood. When the range hood is working, the temperature will continue to rise. When it exceeds the set temperature, the thermal protector will automatically disconnect the power supply.

In short, the bimetal thermal protector is an effective protection device that can effectively avoid accidents such as fire. Using a bimetal thermal protector in a range hood can improve the safety and comfort of the user and is a technical solution worthy of promotion and application.
