Abstract
The utility model relates to an electromagnetic induction heating electric warming oven, which comprises a metal air supply pipe; multiple circles of electromagnetic coils are distributed on the outer circumference of the metal air supply pipe; a metal shield cover is wrapped on the periphery of the electromagnetic coils; and a temperature sensor is arranged on the metal air supply pipe and is electrically connected with a temperature control device. Due to the adoption of the technical scheme, the electromagnetic induction heating electric warming oven utilizes the electromagnetic induction principle to generate heat and heat air; moreover, compared with the heating effect of the traditional electric heating wire, the energy efficiency is greatly improved, and the adjustable and controllable temperature is sensitive, fast and accurate.
Description
Technical field:
The utility model relates to a kind of electromagnetic induction heating type electric heater.
Background technology:
Traditional electric heater all is to utilize heating wire heating back that air is heated, but this heating wire heating up is longer to the time of design temperature, and the heating process has quite a few electric energy to be converted into electromagnetic wave (comprising infrared ray, visible light etc.) and scatters and disappears, the efficiency of heating surface is very low, and when regulating temperature, reaction time is long, and temperature deviation is bigger.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of energy-conservation, electromagnetic induction heating type electric heater that the efficiency of heating surface is high is provided.
For achieving the above object, the technical scheme that the utility model provides is: a kind of electromagnetic induction heating type electric heater includes the metal ajutage, distribution multiturn solenoid on the excircle of metal ajutage.
Periphery at solenoid is enclosed with metallic shield.
The metal ajutage is provided with temperature inductor, and this temperature inductor is connected with the attemperating unit circuit.
After adopting technique scheme, this electric electric heater is to utilize electromagnetic induction principle to produce heat, and air is heated, and has greatly improved efficiency than traditional electrothermal wire heating, and regulates controllable temperature sensitivity, quick, accurate.
Description of drawings:
Fig. 1 is the structural representation of the utility model electric heater.
The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
The electric heater of present embodiment includes metal ajutage 1, even distribution multiturn solenoid 2 on the excircle of metal ajutage 1.In order to prevent the influence of electromagnetic radiation, be enclosed with metallic shield 3 in the periphery of solenoid 2 to human body.Metal ajutage 1 is provided with temperature inductor 4, under temperature inductor 4 be thermocouple, this thermocouple is connected with attemperating unit circuit on the metal ajutage 1, by the monitoring of thermocouple and attemperating unit, can understand the temperature of metal ajutage 1 at any time, thereby effectively regulate and control heating-up temperature.
Traditional electrical radiator resistance wire heat coil is changed into solenoid, solenoid is passed to the electric current of 20KHz～80KHz, solenoid produced alternating magnetic field when electric current passed through, the induction of metal ajutage produces little eddy current, metal ajutage metallic walls is generated heat voluntarily, directly heat the air that passes through, when temperature reaches setting value, sample to attemperating unit by thermocouple, by the size of attemperating unit control electric current.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
