Embodiment Construction

[0010] As shown in the accompanying drawings, an electric heater includes a housing 3, and the housing 3 is provided with an electrothermal film heating body 6 capable of infrared heating the liquid flow flowing through its inner cavity. The electrothermal film heating body 6 includes several The end of the electric heating tube 61 is connected in series through the connecting pipe 62 to form a total liquid inlet and a total liquid outlet; electric heating film. The electrothermal film heating body 6 is liquid-tightly connected in series in the liquid flow path, and the hydraulic pump 5 and the liquid flow sensor 4 that can energize the electrothermal film heating body 5 through the electric control device are connected in series in the liquid flow path, in order to improve the safety factor There are two liquid flow sensors 4, which are respectively connected in series in the liquid flow channels on the water inlet side and the water outlet side of the electrothermal film hea...

Abstract

The invention discloses a electric warming fan which comprises a shell, electric heating film heater set inside the shell able to infrared heat the water flow goes through it inner cavity and sealing connected to flow channel, the channel is linked with hydraulic pump and a flow sensor galvanizing the electric film heater through electric control device, and communicates with the expanding water tank set on upper side inside the shell while its two ends communicating respectively to liquor entrance and liquor exit of the heat exchanger forming a closed ring channel. The closed ring channel is filled with heat exchanging medium. A cross flow blower is set at the air entrance of above heat exchanger while corresponding heat air exit is set on the upper part of the shell. With forced convection of heated air and forced circulation of heat exchanging medium, the heat efficiency of the electric warming fan is enhanced. The electric heating film which has a water electric separation is not only convenient but also safe.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to an electric heater. Background technique [0002] The known electric heater usually directly heats the air with an electric heating body, and transfers heat through radiation and convection. It has the characteristics of low price, small and light, clean and hygienic, etc., but it generally has low thermal efficiency, hot appearance, and even open flames. ,There are security risks. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric heater, which not only has high thermal efficiency, but also is safe to use. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: an electric heater, including a casing, and an electric heating film heating body capable of infrared heating the liquid flow flowing through its inner cavity is arranged inside the casin...
