Inner casing of electric water heater

Abstract

The invention relates to an electric appliance, in particular to an inner casing of an electric water heater. The inner casing of the electric water heater is of an upper casing and lower casing buckling structure, a converter cavity, a controller cavity and a heating device cavity are separately arranged in the sealed upper casing and lower casing, another independent power line lead-in cavity is communicated with other cavities through a hole which serves as a power line lead-in hole, a waterproof connector fixing hole for leading in power lines is arranged on the wall of the outer side, and a sealed cover plate seals up the power line lead-in cavity. A binding post clamping base is arranged in the power line lead-in cavity, and the cover plate is arranged on the power line lead-in cavity. A user interface plate cable lead-in port convenient to seal is arranged on the wall on the outer side of the controller cavity formed by the sealed upper casing and lower casing, a converter and a heater can be installed in other cavities formed by the upper casing and the lower casing, and a fixing support is arranged at the edge of the outside of a lower casing. The inner casing of the electric water heater is good in sealed protection, insulating and waterproof effects and high in safety coefficient and accords with the technical requirements of national standard II-class fast-heating type water heaters.

Description

technical field

[0001] The invention relates to an electric appliance. Background technique

[0002] At present, water heaters in the market are mainly divided into solar energy type, gas heating type and electric heating type. Electric water heaters have a high market share due to their convenient use and installation. The advantages of heating, easy to use, small and beautiful appearance and energy saving are more and more favored by users, and the market share is increasing year by year. However, the electric water heaters on the market, including instant electric water heaters, can only meet the requirements of Class I electrical appliances in the electrical safety standards. In the same cavity of the housing, there is no sealing protection device, the insulation and waterproof effects are poor, and the safety factor is low. Once the water leaks or the circuit board is damp and leaks electricity during use, it is very likely to electrify the water and cause harm to the ...
