Description

Technical Field

[0001] The invention relates to the technical field of heaters, and in particular to a non-radiative bidirectional electromagnetic heater. Background Art

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

[0003] When existing electromagnetic heating devices heat water flow, they usually use electromagnetic coils to heat metal plates, and conduct heat to water flow through the metal plates to achieve heating of the water flow. For example, Chinese patent announcement No. CN107842990A discloses "an electromagnetic heating device", in which the heating unit is arranged in a trapezoidal shape as a whole. The four side surfaces and the top surface of the trapezoidal body are respectively composed of a heating plate, and the five heating plates form an inner cavity of the trapezoidal body. Each surface of the inner cavity formed by the five heating plates is correspondingly provided with an electromagnetic coil. A grid is arranged at the lower end of the trapezoidal body, and the water flow is accelerated by the extrusion part to form turbulence, which effectively improves the heat exchange speed of the water flow itself, and at the same time increases the contact frequency between the water flow and the heating plate, effectively improving the heating efficiency;

[0004] However, in actual use, since electromagnetic coils are provided on the five surfaces of the heating unit, the heating device itself consumes a lot of electricity, and part of the magnetic field generated by the electromagnetic coils is absorbed by the heating unit, and part of it is lost along the inner wall of the water tank, causing waste. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that the heating unit itself consumes a lot of power, and the magnetic field generated by the electromagnetic coil is partially absorbed by the heating unit and partially lost along the inner wall of the water tank, causing waste, and a non-radiative bidirectional electromagnetic heater is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A non-radiative bidirectional electromagnetic heater is designed, comprising a shell, an induction coil is arranged in the shell, a fixing assembly matched with the induction coil is arranged in the shell, a heating chamber is arranged in the shell, the heating chamber is separated by the fixing assembly to form two heating chambers, a water inlet pipe and a water outlet pipe are fixedly arranged on both sides of the shell, a connecting hole is opened on the shell, the water inlet pipe and the water outlet pipe are respectively welded and fixed to the connecting hole, and connecting pipes are arranged on both sides of the shell;

[0008] The shell includes two connecting parts that are arranged opposite to each other. The outsides of the connecting parts are fixedly provided with connecting rings. The fixing assembly is arranged between the two connecting rings. 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 arranged between the two fixing plates.

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

[0011] Furthermore, a through slot is provided on one side of the accommodating slot, and the through slot is used for connecting the wire.

[0012] Furthermore, a filter assembly is arranged in the water inlet pipe of the shell, and the filter assembly includes a filter net.

[0013] Furthermore, a retaining ring is fixedly provided inside the water inlet pipe, a magnet is fixedly provided on the retaining ring, and a metal ring adsorbed by the magnet is fixedly provided outside the filter screen.

[0014] Furthermore, the two heating chambers are each provided with an induction plate matched with the induction coil, and the two connecting pipes are connected by a hose.

[0015] The invention proposes a non-radiative bidirectional electromagnetic heater, which has the following beneficial effects:

[0016] In the present invention, the two connecting parts of the shell are heated by the induction coil, so that one induction coil heats the two connecting parts at the same time, making full use of the magnetic field of the heating coil, avoiding waste, reducing energy waste, so that the water in the two heating chambers is heated, and the two heating chambers are connected, and the water flows through the two heating chambers in sequence, thereby increasing the heating time;

[0017] Secondly, in the present invention, a receiving groove is provided to place the induction coil to prevent the friction between the two fixing plates during installation from damaging the induction coil, and a filtering structure is provided to filter impurities in the water to prevent impurities from accumulating in the heating chamber and causing blockage.

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 hose 13. The water flow passes through the two heating chambers 41 in turn, which increases the heating time, heats the water flow, and improves the heating effect. The shell 1 formed by the two connecting parts 14 can effectively block radiation and reduce damage to the human body.

[0027] Furthermore, in this embodiment, the fixing assembly 3 includes two fixing plates 31 , both of which are insulating plates, and the induction coil 2 is arranged between the two fixing plates 31 , both of which are insulating plates, which effectively prevent 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 , so as to prevent the two fixing plates 31 from rubbing and damaging the induction coil 2 during installation.

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