Problems solved by technology

However, the very obvious defect of this technical solution is that a large number of heat dissipation deflectors and supporting frames for supporting the heat dissipation deflectors are installed in the housing, which not only has a complex structure but also has high manufacturing costs and troublesome product assembly. If the surface of the heat dissipation deflectors Accumulated dust, not only the heat dissipation effect is significantly reduced but also the maintenance is very cumbersome

Abstract

The invention discloses an electric heater, comprising an air inlet, an air outlet and a heating element, wherein, the heating element is laterally arranged between the right side wall and the left side wall of a shell, the outer wall of the front side of the shell is in a shape of grid to form a first separation net; a honeycomb-shaped cellular board is arranged on the rear surface of the first separation net; the hole wall of a honeycomb-shaped small hole is provided with a reflecting surface; the heating element is positioned in a heating containing cavity which is formed between a reflecting plate and the cellular board; the reflecting plate is obliquely arranged in the containing cavity and the reflecting surface of the reflecting plate is basically parallel towards the heating element; an air inlet port of the reflecting plate is arranged on the reflecting plate; cold air outside the shell enters into and along the heating containing cavity to rise gradually and is heated continuously, and finally is discharged from an air outlet port at the top of the shell. The technology of the invention has the advantages of simple structure, good heating effect and being applicable to the electric heater products.

Description

technical field [0001] The present invention relates to an electric heater used for heating office or room and other similar occasions. Background technique [0002] The existing electric heater is composed of a shell and a heating tube. The heat generated by the heating tube is reflected by the reflection of the reflector and heated to a specific part or area. Obviously, this kind of electric heater can only be effective for local heating. excellent results. If it is necessary to evenly heat up the entire relatively large space, it seems powerless. [0003] For this reason, someone has proposed a technical scheme utilizing radiator fins to manufacture electric heaters. The typical document is that the Chinese Patent No. disclosed on February 27, 2002 is CN01224278.0, and the name is called the patent of "a kind of electric heater". Secondly, the date of application is May 23, 2003, the patent No. is US6901213, and the U.S. patent named "Electric heater" (electric heater) ...
