Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic heating, in particular to a steady-current electromagnetic heating device. Background Art

[0002] Electromagnetic heating, also known as electromagnetic induction heating, is based on the principle of generating an alternating magnetic field through the components of an electronic circuit board. When an iron-containing container is placed in this alternating magnetic field, the surface of the container will cut the alternating magnetic field lines, thereby generating alternating currents in the metal part at the bottom of the container. These eddy currents cause the carriers at the bottom of the container to move irregularly at high speed, and the carriers collide and rub against each other, thereby generating heat energy, thereby achieving the effect of heating the object.

[0003] The advantages of electromagnetic heating technology include fast heating speed. The electromagnetic heater can quickly increase the temperature of the heating body in a short time. It is energy-saving and environmentally friendly. The electromagnetic heater has no open flame. The pot body itself generates heat, which reduces heat transfer losses. Its thermal efficiency can reach 96% to 98% or more. There is no exhaust gas emission and no noise, which greatly improves the working environment. It is multifunctional. The electromagnetic heating system is widely used and can be used in plastic machines, reactors, water heating, oil heating, diffusion pump heating, northern heating furnaces and other fields. It is safe and hygienic. The electromagnetic heater uses electromagnetic induction heating. There is no open flame or heat radiation during heating, and no secondary pollutants are generated. It is clean, hygienic, environmentally friendly and safe. The electromagnetic heating controller is not prone to leakage like gas, and does not produce open flames. Its safety is significantly better than other heating equipment.

[0004] However, when a common steady-flow electromagnetic heating device heats water, steam will be generated. The steam will cause the internal pressure of the water tank to increase. Other devices need to be added to control the internal pressure and discharge the steam directly, which will cause heat loss in the steam. In view of this, the present application proposes a steady-flow electromagnetic heating device. Summary of the invention

It solves the problem that steam is generated after water is heated, and the steam will cause the internal pressure of the water tank to increase, requiring other devices to be added to control the internal pressure and directly discharge the steam, resulting in heat loss in the steam.

The steady-current converter 3 controls the input current, rectifies the alternating current into direct current, and then converts the direct current into high-frequency high-voltage electricity or high-frequency low-voltage high-current electricity, driving the electromagnetic heater 2 to heat.

[0028] The exhaust assembly 4 includes an exhaust pipe 41 fixedly installed on the top of the water tank 1 , an exhaust motor 42 is fixedly installed on the top of the exhaust pipe 41 , and an exhaust fan 43 is fixedly installed at the output end of the exhaust motor 42 located inside the exhaust pipe 41 .

[0029] Secondly, a deflector 411 is fixedly mounted at one end of the exhaust pipe 41 located inside the water tank 1, and the outer edge of the bottom of the deflector 411 contacts the inner wall of the water tank 1.
