Electric heater with inner wall conveniently cleaned

Abstract

The invention discloses an electric heater with the inner wall conveniently cleaned. The electric heater comprises a heating box. A plug plate is sleeved with an opening in one side of the heating box in a connected manner and is of a hollow structure. One side of the plug plate is fixedly connected with one side of a vertical plate. The upper end and the lower end of the vertical plate are movably connected with one ends of two movable plates correspondingly. The opposite sides of the two movable plates are movably connected with the surface of the heating box through springs. The other ends of the movable plates are fixedly connected with one ends of clamping plates. The other ends of the two clamping plates are clamped and connected in two clamping grooves formed in the surface of the heating box. Through the improvement on the plug plate, when the clamping plates are clamped in the clamping grooves, the clamping plates can abut against the plug plate connected with the vertical plate, the plug plate can be conveniently taken out, and therefore the inner wall of the heating box can be conveniently cleaned; and through the improvement on brush plates, the inner wall of the heating box can be washed through brushing, a telescopic air cylinder can drive the brush plates to move left and right, and the effect of thorough brushing is achieved.

Description

technical field [0001] The invention relates to the technical field of electric motor heaters, in particular to an electric heater for cleaning inner walls. Background technique [0002] Electric heating is the process of converting electrical energy into heat energy. It is an internationally popular high-quality and long-life electric heating equipment. It is used to raise, keep warm and heat flowing liquid and gaseous media. The heating chamber of the heater adopts the principle of fluid thermodynamics to uniformly take away the huge heat generated by the electric heating element, so that the temperature of the heated medium meets the user's process requirements. [0003] After a long period of use, the electric heaters currently on the market will accumulate a lot of dirt on the inner wall, which will produce peculiar smell and reduce the service life of the electric heaters. However, the current electric heaters are basically integrated. It is difficult to clean the inn...
