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. 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.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention based on specific situations.

[0019] As shown in the figure, a high-safety electric heater includes an electric heating assembly 1 and an electric heating pipe shield 2. The electric heating assembly 1 includes a fixing fla...

Abstract

The invention provides a high-safety electric heater, which comprises an electric heating assembly and an electric heating tube shield, wherein the electric heating assembly comprises a fixed flange and 18 U-shaped tubes, the fixed flange is further provided with a temperature sensor, and the electric heating tube shield comprises a wiring shield and a protective cover. According to the invention,the U-shaped tubes can be made shorter under the condition that the diameter is not changed, a smaller container can be selected after the U-shaped tubes are made shorter, and the heat dissipation area is increased due to the fact that the number of the distributed U-shaped tubes is large, so that the surface load is low, and the service life is longer; the wiring shield and the protective coverare molded at one time by a mold, so that the working hours consumed in original metal processing are greatly shortened, the material is an insulating high-temperature-resistant material, and the insulating property is greatly improved. The inner wall of the wiring shield is further provided with a temperature sensor jack, so that an electric wire of the temperature sensor is not contacted with ahigh voltage part in the heater, the safety is ensured, and the mounting and dismounting of the protective cover are not influenced.

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. 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 solution of the present invention to solve the above problems is: a high-safety el...
