[0003] Water heaters are usually installed with an overvoltage protector for circuit protection during use. However, some electric water heaters are installed in the bathroom for bathing. Since water vapor will be generated in the bathroom during bathing, it is easy to cause the overvoltage protector to be short-circuited due to moisture. Tripping often occurs, which affects the use of electric water heaters. At the same time, when the water inside the electric water heater is heated, steam will be generated, which will cause the air pressure inside the electric water heater to increase. When the air pressure is too high, it will easily cause the inner tank of the electric water heater to expand and deform. , or even the danger of explosion, for this reason we provide an intelligent overvoltage protection device for electric water heaters

The invention discloses an intelligent overvoltage protection device of an electric water heater, relates to the technical field of electric water heaters, and in particular to the intelligent overvoltage protection device of the electric water heater which comprises an electric water heater body, a power line is fixedly connected to the right side of the electric water heater body, a sealing protection cover is arranged in the middle of the power line, an overvoltage protector is fixedly installed inside the sealing protection cover, the sealing protection cover comprises a lower protection cover body and an upper protection cover body, a sealing groove is formed in the outer portion of the lower protection cover body, and a lower sealing piece is fixedly connected to the bottom of the lower protection cover body. The sealing protection cover is arranged outside the overvoltage protector, the lower protection cover and the upper protection cover are used for protecting the overvoltageprotector, a sealing strip is connected inside the sealing groove in a clamping mode, water is prevented from entering the connecting position of the lower protection cover and the upper protection cover, a sealing rubber plug can seal the connecting position outside the power line, and the water is prevented from entering the overvoltage protector to be damped.
Description
technical field [0001] The invention relates to the technical field of electric water heaters, in particular to an intelligent overvoltage protection device for electric water heaters. Background technique [0002] Electric water heaters refer to water heaters that use electricity as energy for heating. They are one of the three major water heaters alongside gas water heaters and solar water heaters. ), instant heating type and quick heating type (also called semi-storage type). Electric water heaters are smaller in size and more powerful than electric water heaters, so they are indeed faster than storage-type electric water heaters in terms of heating speed. [0003] Water heaters are usually installed with an overvoltage protector for circuit protection during use, but some electric water heaters are installed in the bathroom for bathing. Since water vapor will be generated in the bathroom during bathing, it is easy to cause the overvoltage protector to be short-circuited...
