Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] as attached figure 1 As shown, a fire-resistant electric heater includes a heating body 1 and a fire-proof device 2 wrapped around the heating body 1, and the heating body 1 and the fire-proof device 2 are connected to a controller 3; the fire-proof device 2 includes External waterproof shield and evenly arranged internal fusible protection wires.

[0013] The melting point of the fusible protective wire is lower than the heating threshold of the heating body 1 .

[0014] The fusible protection wire is arranged around the heating body 1 in a spiral shape.

[0015] The fire prevention device 2 is provided with a temperature sensing device. As a double protection sensing device.

[0016] When the heated fluid cannot submerge the temperature sensor in the original device due to evaporation and other factors, resulting in its failure, the heating body 1 continue...

Abstract

The invention discloses a fire-prevention electric heater which comprises a heating body and a fire prevention device wrapping the periphery of the heating body, wherein both the heating body and the fire prevention device are connected with a controller; the fire prevention device comprises an outer waterproof shield and fuse protection wires uniformly arranged in the fire prevention device. The fire-prevention electric heater effectively realizes the normal work of a temperature sensor, protects the heating body, avoids circuit failures and fires caused by the overheating of heating body, and prevents the fires.

Description

technical field [0001] The invention belongs to the field of electric heaters, and in particular relates to a fireproof electric heater. Background technique [0002] Electric heaters are becoming more and more common electrical equipment, especially in fluid electric heaters, which are widely used. Generally, the temperature sensor is used to sense and control the heating degree. However, in actual use, it often occurs after the heating fluid evaporates. , The temperature sensor is vacant, and it cannot continue to effectively sense the failure of the work, resulting in functional failure, affecting the normal operation of the electric heater, and also causing safety hazards due to excessive heating, which leads to high temperature heating of the heating body, which in turn causes open circuit and fire. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a fireproof electric he...
