Problems solved by technology

The resistance wire of the electric heater is made of nickel and chromium alloy, and the temperature is as high as 800°C. The power of the electric heater is relatively large. Most of the existing high-power electric heaters are too large and take up space. The wires at the end of the electric heating tube are messy, and the end of the electric heating tube is overheated during work. These reasons may cause safety accidents such as leakage and short circuit.

Abstract

The invention provides a high-safety electric heater, which includes an electric heating assembly and an electric heating tube shield. The electric heating assembly includes a fixing flange and 18 U-shaped tubes. The fixing flange is also provided with a temperature sensor. The electric heating tube shield includes a wiring shield and a protective cover. The present invention can make the U-shaped tube shorter when the diameter is constant, and can choose a smaller container after being shortened. Due to the distribution of the U-shaped tube The number of roots is more, the heat dissipation area is increased, the surface load will be lower, and the service life will be longer; the wiring shield and the cover are formed by the mold at one time, which greatly shortens the working hours of the original metal processing, and the material is made of insulating and high temperature resistant materials. , the insulation performance has been greatly improved. There is also a temperature sensor jack on the inner wall of the wiring shield, so that the wire of the temperature sensor will not come into contact with the high-voltage part of the heater, ensuring safety without affecting Cover installation and removal.

Description

technical field [0001] The invention relates to the technical field of electric heating, in particular to a high-safety electric heater. Background technique [0002] Electric heater is a kind of equipment used more in work and life, such as electric stove, electric iron, electric iron, electric heater, electric oven, etc. are all electric heating equipment. The resistance wire of the electric heater is made of nickel and chromium alloy, and the temperature is as high as 800°C. The power of the electric heater is relatively large. Most of the existing high-power electric heaters are too large and take up space. The wires at the end of the electric heating tube are messy, and the end of the electric heating tube is overheated during work. These reasons may cause safety accidents such as leakage and short circuit. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a high-safety electric heater. [0004] The technical ...
