[0038] The existing counter balance type heater adopts heat pipe heating, the heat generated by the heat pipe is conducted to the heat conduction sheet and spread to the air through natural convection, so as to achieve the effect of heating. On the one hand, the heat pipe and the heat conduction sheet are connected in a clamping manner, the contact thermal resistance is large, the heat generated on the heat pipe cannot be dissipated in time through the heat conduction sheet, the internal temperature rises high, and the number of heat dissipation sheets needs to be increased to conduct the heat out, which makes the whole machine size longer. At the same time, the connecting ring area between the heat pipe and the heat conduction sheet is small, the heat dissipation effect is poor, and the whole machine heat efficiency is low. On the other hand, due to the power limitation of the heat pipe, the whole machine power is generally only two grades, and cannot be freely adjusted according to the user's demand. Therefore, it can be seen that the heat pipe heating has very obvious limitations, and a heating structure is needed to solve the above problems.

[0039] The utility model provides a kind of heater, please refer to Figures 1 to 6 , the embodiment of the heater proposed in the present application will be specifically described below with reference to specific drawings.

[0040] Please refer to Figures 1 to 6 , the heater 100 includes at least two heating elements 2 and an electromagnetic heating structure 3, at least two heating elements 2 are arranged in the shell 1, and the two heating elements 2 are arranged oppositely and spacedly. The electromagnetic heating structure 3 includes an electromagnetic heating coil assembly 31 arranged in the shell 1, and the electromagnetic heating coil assembly 31 is arranged between the two heating elements 2 to electromagnetically heat the two heating elements 2.

[0041] The technical scheme of the utility model discloses a heater 100 is composed of the heating element 2 and the electromagnetic heating structure 3, the electromagnetic heating structure 3 includes the electromagnetic heating coil assembly 31 that the heating element 2 is heated to make the electromagnetic heating coil assembly 31 can produce the magnetic field of alternate change around the heating element 2 after the electrification of electromagnetic heating coil assembly 31, and the heating element 2 is placed in the change magnetic field and is cut to the magnetic field, causes its own heating, makes the heat dissipation to play the heating function of heater 100.Compared with the structure that traditional heat pipe and heating element 2 abut to can transfer heat to the heating element 2 and exchanges heat with air again, because the heating element 2 is the main medium for heat exchange with air, the electromagnetic heating coil assembly 31 in the application can heat the heating element 2 without contacting the heating element 2, that is, the heating efficiency and heating utilization rate of the electromagnetic heating coil assembly 31 to the heating element 2 are higher, and the electromagnetic heating coil assembly 31 can also realize stepless adjustment of heating power, so that the heating efficiency of heater 100 is higher, and the heating temperature adjustment is more free, more economical and practical.In addition, the magnetic field generated by the electromagnetic heating coil assembly 31 is dispersed towards the surrounding, so at least two heating elements 2 are provided in the application, and the electromagnetic heating coil assembly 31 is arranged between the two heating elements 2, so that the two heating elements 2 are heated by the electromagnetic heating coil assembly 31 at the same time, further improving the heating efficiency and heating utilization rate of the heater 100.

[0042] In addition, the heater also includes a shell 1, the shell 1 is provided with a via hole 11, so that the air outside the shell 1 can exchange with the air in the shell 1 through the via hole 11, and the heating element 2 and the electromagnetic heating structure 3 are arranged in the shell. Specifically, the heating element 2 and the electromagnetic heating structure 3 are built-in in the shell 1, and the via hole 11 is formed in the shell 1, so that the air outside the shell 1 can exchange with the air in the shell 1 through the via hole 11, and the air entering the shell 1 is heated by the heating element 2 and then flows out of the shell 1, that is, the heat generated by the heating element 2 is taken out of the shell 1, meeting the heating function requirement of the heater 100.

[0043] Specifically, the through holes 11 are arranged in multiple numbers, including an air inlet through hole 112 arranged at the upper end of the shell 1 and an air outlet through hole 111 arranged at the lower end of the shell 1. The main function of the through holes 11 is to communicate the air environment inside and outside the shell 1, so that the air inside and outside the shell 1 flows, thereby taking away the heat on the heating element 2 in the shell 1 by air as a medium, and achieving the effect of heating the environment outside the shell 1, i.e. the heating effect of the warmer 100. Therefore, the specific number and arrangement form of the through holes 11 can not be limited as long as the air exchange between the inside and outside of the shell 1 can be achieved. In this application, the through holes 11 are arranged in multiple numbers to improve the heat exchange efficiency. On this basis, it can be understood that the density of hot air is less than that of cold air, i.e. the density of cold air entering the shell 1 becomes smaller after being heated by the heating element 2, and the cold air will move upwards to form an air flow from bottom to top. Therefore, according to the principle, the multiple through holes 11 are arranged as the air outlet through hole 111 at the upper end of the shell 1 and the air inlet through hole 112 at the lower end of the shell 1, so as to normally achieve the heating function of the warmer 100 without additional air driving devices, and meet the use requirements.

[0044] Specifically, the air outlet through hole 111 is arranged at the top of the shell 1, and the air inlet through hole 112 is arranged at the bottom of the shell 1. The through holes 11 are divided into the air outlet through hole 111 at the upper end of the shell 1 and the air inlet through hole 112 at the lower end of the shell 1, which has been described above. On this basis, the air inlet through hole 112 and the air outlet through hole 111 can be arranged on the side wall of the shell 1, or on the top and bottom of the shell 1, which is not limited here and can all achieve the above-mentioned air flow function to meet the heating requirements. In this embodiment, the air outlet through hole 111 is arranged at the top of the shell 1, and the air inlet through hole 112 is arranged at the bottom of the shell 1. On the one hand, no holes are made on the side wall of the shell 1, so the appearance effect is good. On the other hand, an up-down air duct is formed in the shell 1, so that the air flow is less hindered by the shell 1, the air flow efficiency is higher, the air exchange effect is good, and the heating effect of the warmer 100 is improved. On the other hand, the air inlet through hole 112 is arranged at the bottom of the shell 1, so it is not easy to suck in sundries.

[0045] Further, the shell 1 is arranged in an elongated shape along the transverse direction. The shape of the shell 1 can not be limited, but in order to fit the indoor use scene of a family, the shell 1 is arranged in an elongated shape along the transverse direction, which is more convenient for placing the warmer 100 and has a wider heating range.

[0046] Specifically, the two heating elements 2 are arranged opposite and spaced apart in the lateral direction, and the electromagnetic heating coil assembly 31 is arranged extending in the upward-downward direction. Based on the structure feature that the shell 1 is long in the lateral direction, in some embodiments, the electromagnetic heating coil assembly 31 is arranged in the lateral direction, i.e., extending in the direction in which the shell 1 extends, so that the shape of the shell 1 does not limit the size of the electromagnetic heating coil assembly 31, thereby ensuring the working power of the electromagnetic heating coil assembly 31. At this time, the two heating elements 2 can also be arranged in the lateral direction to avoid the limitation of the shell 1. In other embodiments, the two heating elements 2 can also be arranged opposite and spaced apart in the lateral direction, and the corresponding electromagnetic heating coil assembly 31 needs to be arranged extending in the upward-downward direction. In this way, the electromagnetic heating coil assembly 31 and the heating element 2 are limited by the shape of the shell 1, so that the assembly formed by the two has a smaller size in the lateral direction. Therefore, the heating power can be improved by arranging multiple groups of the above assemblies in the lateral direction to meet the heating power requirement of the warmer 100. That is, the heating element 2 and the electromagnetic heating coil assembly 31 can be arranged in various forms in the shell 1, which can ensure the final heating performance of the warmer 100, and therefore, no specific limitation is made here.

[0047] In addition, the shell 1 is provided with a heat insulation plate 12, and the heat insulation plate 12 and the shell 1 jointly form a heat insulation cavity 13. The warmer 100 also includes an electric control assembly 4, and the electric control assembly 4 includes at least one electrical component arranged in the heat insulation cavity 13. Generally, the electric control assembly 4 cannot withstand high temperature, so in some embodiments, the electric control assembly 4 can be arranged outside the shell 1 to be separated from the inner cavity of the shell 1. However, this arrangement cannot avoid the part of the electric control assembly 4 extending into the shell 1, and also affects the appearance of the warmer 100. Therefore, in the present embodiment, the heat insulation plate 12 is arranged in the shell 1 to form the heat insulation cavity 13 by surrounding the heat insulation plate 12 and the shell 1, so that the electric control assembly 4 can be arranged in the heat insulation cavity 13 to avoid the high-temperature air in the shell 1, thereby avoiding damage to the electric control assembly 4 due to heat. At the same time, the electric control assembly 4 is not arranged outside the shell 1 to avoid affecting the appearance of the warmer 100, and also to avoid the safety hazard caused by the electrical components of the electric control assembly 4 being arranged outside.

[0048] Further, the through holes 11 are arranged in multiple, including air outlet through holes 111 arranged on the top of the shell 1 and air inlet through holes 112 arranged on the bottom of the shell 1; the heat insulation plates 12 are arranged corresponding to the side of the shell 1 to form the heat insulation cavities 13 together with the side of the shell 1. The air outlet through holes 111 arranged on the top of the shell 1 and the air inlet through holes 112 arranged on the bottom of the shell 1 have been described in detail above, and will not be repeated here. Based on the arrangement position of the through holes 11 described herein, when the heat insulation plates 12 are arranged corresponding to the side of the shell 1, the heat insulation plates 12 will not block the circulation of air from the air inlet through holes 112 to the air outlet through holes 111, and at the same time, because the air flow will not flow towards the heat insulation plates 12, the temperature in the heat insulation cavities 13 is relatively lower, which can better protect the electric control assembly 4 from high temperature.

[0049] Further, the inner side of each side of the shell 1 is arranged corresponding to the heat insulation plate 12, so that the heat insulation cavities 13 are formed on the circumferential side of the heat generating member 2. The heat insulation plate 12 is arranged mainly for high temperature protection of the electric control assembly 4. In this embodiment, the inner side of each side of the shell 1 is arranged corresponding to the heat insulation plate 12, so that the heat insulation cavities 13 are formed on the circumferential side of the heat generating member 2. It can be understood that the inner circumferential side of the shell 1 is arranged with the heat insulation cavities 13, which on one hand does not affect the circulation of air from bottom to top to realize the heating function, and on the other hand avoids heating of the shell 1 to avoid the user from being scalded by touching the warmer 100 during use of the warmer 100, which ensures the heating function of the warmer 100 and at the same time ensures the safety of the user.

[0050] Further, the heat insulation cavity 13 is provided with a fan 5, the shell 1 is provided with an air inlet 14 corresponding to the heat insulation cavity 13, and the top of the shell 1 or the heat insulation plate 12 is provided with an air outlet 15. In order to further improve the heat insulation capacity of the heat insulation cavity 13, the fan 5 is additionally arranged in the heat insulation cavity 13 on the basis of the heat insulation plate 12, the air inlet 14 is arranged on the shell 1 corresponding to the heat insulation cavity 13, and the air outlet 15 is arranged on the top of the shell 1 or the heat insulation plate 12, so that the fan 5 drives the gas in the heat insulation cavity 13 to flow, the low-temperature air outside the shell 1 is sucked into the heat insulation cavity 13, and the air with a higher temperature in the heat insulation cavity 13 is blown out from the air outlet 15. It can be understood that the position of the air inlet 14 is not limited here, and the air inlet 14 is arranged on the shell 1. The air is driven to flow by the fan 5, and the air inlet 14 can be arranged on any position of the shell 1. The cold air outside the shell 1 can be sucked into the heat insulation cavity 13. Of course, the effect is better when the air inlet 14 is arranged on the lower part of the shell 1, and the air outlet 15 is arranged on the top of the shell 1 or the heat insulation plate 12, that is, the air outlet 15 is arranged along the natural flowing direction of the air with a higher temperature, so that the air with a higher temperature flows out of the heat insulation cavity 13 more easily, the working power of the fan 5 is reduced, the energy consumption is reduced, and the noise of the fan 5 is reduced.

[0051] In addition, the electromagnetic heating structure 3 further comprises a magnet structure 32 arranged outside the electromagnetic heating coil assembly 31 to expose the electromagnetic heating coil in the direction towards the heating element 2. As described above, the magnetic field generated by the electromagnetic heating coil assembly 31 is in the form of divergence to the surrounding, and the two heating elements 2 in the application can only be arranged on the two sides of the electromagnetic heating coil assembly 31. In order to improve the heating efficiency and heating energy efficiency of the electromagnetic heating coil assembly 31, the magnet structure 32 is arranged outside the electromagnetic heating coil assembly 31 in the embodiment to attract the magnetic field generated by the electromagnetic heating coil assembly 31 by the magnetic force of the magnet structure 32, so as to give the gathering effect of the magnetic field generated by the electromagnetic heating coil assembly 31, thereby improving the heating efficiency of the electromagnetic heating coil assembly 31 on the heating element 2 and meeting the above requirements.

[0052] Further, the heating element 2 comprises a heating body 21 and fins 22 in thermal conduction with the heating body 21; the electromagnetic heating coil assembly 31 is used to electromagnetically heat the heating body 21. It can be understood that the heat exchange efficiency of the heating element 2 with air is related to the contact area of the heating element 2 with air, so as to improve the heat dissipation efficiency of the heating element 2 and improve the heating performance of the warmer 100, in the embodiment, the heating element 2 is provided as the combination of the heating body 21 and the fins 22, the fins 22 are in thermal conduction with the heating body 21, the electromagnetic heating coil assembly 31 is used to electromagnetically heat the heating body 21, the heat on the heating body 21 can be conducted to the fins 22, so that through the contact of the fins 22 with air, the contact heat exchange area of the heating element 2 with air is greatly improved, thereby improving the heating performance of the warmer 100.

[0053] Further, the fins 22 and the heating body 21 are integrally provided, or the fins 22 and the heating body 21 are separately provided. The specific arrangement mode of the fins 22 and the heating body 21 is not limited, that is, the fins 22 can be integrally formed with the heating body 21, or the fins 22 and the heating body 21 can be independently formed and then combined and fixed by other thermal conduction fixing mode, which can realize the conduction of heat on the heating body 21 to the fins 22. Specifically, the integrally provided mode of the fins 22 and the heating body 21 can be integrally die-casting, spraying a metal layer on the surface of the fins 22, etc., and the combined and fixed mode of the separately provided fins 22 and the heating body 21 can be welding, riveting, etc.

The fins 22 comprise a plurality of fin units 23 protruding from the heating body 21, that is, the fin units 23 are arranged in a direction away from the heating body 21, and the cross-sectional shape of the fin unit 23 can be a triangle or a quadrilateral in the application. On this basis, the fin unit 23 can be a hollow structure extending upward and downward, that is, the cross-sectional shape of the fin unit 23 is a triangular frame or a quadrilateral frame, which on the one hand reduces the mass of the fin unit 23, and on the other hand improves the heat exchange area of the fin unit 23 with air and improves the heat exchange performance. Further, when the fins 22 and the heating body 21 are separately provided, the fins 22 can be a wave structure formed by bending a metal sheet, and then the turning points of the wave structure are fixed to the heating body 21 to form the combination of the heating body 21 and the fins 22, that is, to form the heating element 2 with the cross-sectional shape of the triangular frame or the quadrilateral frame.
