Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a non-radioactive bidirectional electromagnetic heater. Background Technology

[0002] Electromagnetic induction heating, or simply induction heating, is a method of heating conductive materials such as metals. Induction heating uses electromagnetic induction to generate current inside the material being heated, relying on the energy of these eddy currents to achieve the heating purpose. The basic components of an induction heating system include an induction coil, an AC power supply, and a workpiece. Depending on the object being heated, the coil can be made into different shapes. The coil is connected to the power supply, which provides alternating current to the coil. The alternating current flowing through the coil generates an alternating magnetic field that passes through the workpiece. This magnetic field causes eddy currents in the workpiece to be generated, thus heating it.

[0003] Existing electromagnetic heating devices typically use electromagnetic coils to heat metal plates when heating water flow. The heat is then conducted to the water flow through the metal plates. For example, Chinese Patent Publication No. CN107842990A discloses "an electromagnetic heating device" in which the heating unit is arranged in a trapezoidal shape. Each of the four sides and the top of the trapezoid is composed of a heating plate, and the five heating plates form the inner cavity of the trapezoid. An electromagnetic coil is set on each side of the inner cavity formed by the five heating plates. A grid is set at the lower end of the trapezoid. The water flow is accelerated by the extrusion part, thereby forming turbulence, which effectively improves the heat exchange speed of the water flow itself. At the same time, it increases the contact frequency between the water flow and the heating plate, which effectively improves the heating efficiency.

[0004] However, in actual use, because electromagnetic coils are installed in all five sides of the heating unit, the heating device itself consumes a lot of electricity. In addition, part of the magnetic field generated by the electromagnetic coil is absorbed by the heating unit, and part of it is lost along the inner wall of the water tank, resulting in waste. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as high power consumption of the heating unit itself, partial absorption of the magnetic field generated by the electromagnetic coil by the heating unit, and partial loss along the inner wall of the water tank, resulting in waste. Therefore, this invention proposes a radiation-free bidirectional electromagnetic heater.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a radiation-free bidirectional electromagnetic heater, including a housing, an induction coil disposed inside the housing, a fixing component that cooperates with the induction coil disposed inside the housing, a heating chamber disposed inside the housing, the heating chamber being separated by the fixing component to form two heating chambers, an inlet pipe and an outlet pipe fixedly disposed on both sides of the housing respectively, and a connecting pipe provided on both sides of the housing;

[0008] The housing includes two oppositely arranged connecting parts, each of which is fixedly provided with a connecting ring on its exterior. The fixing component is disposed between the two connecting rings, and the two connecting rings are connected by bolts.

[0009] Furthermore, the fixing assembly includes two fixing plates, both of which are insulating plates, and the induction coil is disposed between the two fixing plates.

[0010] Furthermore, each of the fixed plates is provided with a receiving groove, and the induction coil is disposed between two receiving grooves.

[0011] Furthermore, a through groove is provided on one side of each of the receiving grooves, and the through groove is used to connect the wires.

[0012] Furthermore, a filter assembly is provided inside the water inlet pipe of the housing, and the filter assembly includes a filter screen.

[0013] Furthermore, a retaining ring is fixedly installed inside the water inlet pipe, a magnet is fixedly installed on the retaining ring, and a metal ring that is attracted to the magnet is fixedly installed on the outside of the filter screen.

[0014] Furthermore, each of the two heating chambers is equipped with an induction plate that cooperates with the induction coil, and the two connecting pipes are connected by a flexible hose.

[0015] The present invention proposes a radiation-free bidirectional electromagnetic heater, the advantages of which are as follows:

[0016] In this invention, the two connecting parts of the housing are heated by an induction coil, thereby enabling one induction coil to heat the two connecting parts simultaneously. This fully utilizes the magnetic field of the heating coil, avoids waste, reduces energy waste, and ensures that the water in both heating chambers is heated. Furthermore, the two heating chambers are connected, and the water flows through the two heating chambers sequentially, increasing the heating time.

[0017] Secondly, in this invention, by setting a receiving groove to place the induction coil, the friction between the two fixing plates during installation is prevented from damaging the induction coil. By setting a filter structure to filter impurities in the water, impurities are prevented from accumulating in the heating chamber and causing blockage. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A radiation-free bidirectional electromagnetic heater includes a housing 1, an induction coil 2 inside the housing 1, a fixing component 3 that cooperates with the induction coil 2 inside the housing 1, a heating chamber 4 inside the housing 1, the heating chamber 4 being separated by the fixing component 3 to form two heating cavities 41, an inlet pipe 11 and an outlet pipe 12 fixedly installed on both sides of the housing 1 respectively, and a connecting pipe on both sides of the housing 1.

[0025] The housing 1 includes two metal connecting parts 14 arranged opposite to each other. A connecting ring 15 is fixedly provided on the outside of each connecting part 14. The fixing component 3 is disposed between the two connecting rings 15. The two connecting rings 15 are connected by bolts 16.

[0026] In this invention, the induction coil 2 heats the two connecting parts 14 of the housing 1, and the two connecting parts 14 heat the water in the two heating chambers 41 respectively. The two heating chambers 41 heat the water flow simultaneously, doubling the amount of water heated and improving the heating efficiency. In this embodiment, the connecting pipe can be used as an inlet pipe or an outlet pipe, and the two connecting pipes can be connected by a flexible hose 13. The water flow passes through the two heating chambers 41 in sequence, increasing the heating time and raising the water temperature, thus improving the heating effect. The housing 1 formed by the two connecting parts 14 can effectively shield radiation and reduce damage to the human body.

[0027] Furthermore, in this embodiment, the fixing component 3 includes two fixing plates 31, both of which are insulating plates. The induction coil 2 is disposed between the two fixing plates 31, which are also insulating plates, effectively preventing the magnetic field from being blocked by the fixing plates 31.

[0028] Furthermore, in this embodiment, each of the fixing plates 31 is provided with a receiving groove 32, and the induction coil 2 is disposed between two receiving grooves 32 to prevent the two fixing plates 31 from rubbing and damaging the induction coil 2 during installation.

[0029] It should be noted that in this embodiment, a through groove 33 is provided on one side of the receiving groove 32. The through groove 33 is used to connect the wires and prevent the two fixing plates 31 from rubbing and damaging the wires during installation.

[0030] Furthermore, in this embodiment, a filter assembly 5 is provided inside the water inlet pipe 11 of the housing 1. The filter assembly 5 includes a filter screen 51, which filters impurities in the water to prevent impurities from accumulating in the heating chamber 41 and causing blockage.

[0031] More specifically, in this embodiment, a retaining ring 52 is fixedly installed inside the water inlet pipe 11, and a magnet 53 is fixedly installed on the retaining ring 52. A metal ring 54 that is attracted to the magnet 53 is fixedly installed on the outside of the filter screen 51. The filter screen 51 is prevented from falling off by magnetic attraction between the magnet 53 and the metal ring 54. When the filter screen 51 needs to be removed, water is injected from the water outlet pipe 12, and the water flow is used to flush the filter screen 51 out of the water inlet pipe 11.

[0032] In some embodiments, each of the two heating chambers 41 is provided with an induction plate that cooperates with the induction coil 2. The two connecting pipes are connected by a flexible hose 13. By setting the induction plate to cooperate with the induction coil 2, the induction coil 2 heats the two induction plates 6, thereby heating the water flow in the two heating chambers 41, doubling the amount of water heated. The two connecting pipes can be connected by the flexible hose 13, and the water flow passes through the two heating chambers 41 in sequence, increasing the heating time, raising the water temperature, and improving the heating effect.

[0033] Working method: During operation, the induction coil 2 heats the two connecting parts 14 or the two induction plates 6 of the housing 1. The two connecting parts 14 heat the water in the two heating chambers 41 respectively. The two heating chambers 41 heat the water flow at the same time, doubling the amount of water heated and improving the heating efficiency. The two connecting pipes can be connected by the hose 13, and the water flow passes through the two heating chambers 41 in sequence, increasing the heating time and raising the water temperature, thus improving the heating effect.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
