[0040] Currently, skirting boards are natural convection heaters. Their principle is to install an air heating device at the bottom. When heated, the air density decreases and rises, creating convection. Existing heaters typically use long, rectangular electric heating tubes, which cannot adjust the temperature field along their length and cannot meet the temperature requirements of different heating areas.

[0041] Based on this, the utility model provides a heater, which aims to solve the problem that the heating area of the existing heater cannot be adjusted. Figures 1 to 6 This is a structural schematic diagram of the heater provided by the utility model.

[0042] See also Figures 1 to 4In one embodiment of the present invention, the heater 100 includes a shell 1, an electromagnetic heating structure and an electromagnetic heating structure 3. The shell 1 is provided with a through hole 11 so that air can be exchanged with air outside the shell 1 through the through hole 11. The electromagnetic heating structure includes a heating element 21 arranged in the shell 1. The electromagnetic heating structure 3 includes a plurality of electromagnetic coil assemblies 31. At least one of the electromagnetic coil assemblies 31 is used to electromagnetically heat the heating element 21, and at least two electromagnetic coil assemblies 31 are arranged in parallel so that they can be independently controlled.

[0043] In the technical solution of the present invention, the through hole 11 is adopted to allow air to enter and exit the shell 1, so that the hot air in the shell 1 can exchange heat with the cold air outside the shell 1 to increase the temperature of the surrounding environment. The heating element 21 is adopted to heat the air flowing into the shell 1, and a plurality of electromagnetic coil assemblies 31 are adopted to electromagnetically heat the heating element 21. At the same time, at least two electromagnetic coil assemblies 31 are arranged in parallel to independently control the electromagnetic coils for electromagnetic heating. In this way, by setting the electromagnetic coil assemblies 31 arranged in parallel, different numbers or positions of the electromagnetic coil assemblies 31 can be opened as needed, so that the heater 100 can form different heating areas, so that the heater 100 can adapt to different heating areas, thereby solving the problem that the heating area of the existing heater 100 cannot be adjusted.

[0044] The at least two electromagnetic coil assemblies 31 may have only a portion thereof corresponding to heating the heating element 21, while the other portion may heat other components that require electromagnetic heating. Alternatively, the at least two electromagnetic coil assemblies 31 may both heat the heating element 21. Of course, the number of heating elements 21 may be one or more.

[0045] It should be noted that there are multiple numbers of the electromagnetic coil assemblies 31, which can be three, four, etc., and the present invention does not limit this. For example, the multiple electromagnetic coil assemblies 31 include a first electromagnetic coil assembly, a second electromagnetic coil assembly, and a third electromagnetic coil assembly arranged in parallel. When the first electromagnetic coil assembly, the second electromagnetic coil assembly, and the third electromagnetic coil assembly are turned on respectively, only the heating element 21 corresponding to the first electromagnetic coil assembly, the electromagnetic coil assembly, or the third electromagnetic coil assembly is electromagnetically heated, so that the heating element 21 only heats the air in the corresponding area. Of course, in other embodiments, the first electromagnetic coil group and the second electromagnetic coil assembly can be turned on at the same time, or the first electromagnetic coil assembly, the second electromagnetic coil assembly, and the third electromagnetic coil assembly can be turned on at the same time, etc. The specific details can be adjusted as needed, and the present invention does not limit this.

[0046] Since the density of hot air is relatively low, the air in the shell 1 generally flows upward after being heated. For this reason, in this embodiment, the through holes 11 are provided in plurality, and the plurality of through holes 11 include air inlet through holes provided at the bottom of the shell 1 and air outlet through holes provided at the top of the shell 1, so that the air in the shell 1 can flow from bottom to top to adapt to the flow of hot air, so that the hot air in the shell 1 can be discharged in time, which can not only improve the heating effect of the heater 100, but also avoid heat accumulation in the shell 1.

[0047] In one embodiment of the present invention, please refer to Figures 1 to 3 The shell 1 is extended in a transverse direction and is long in shape. Thus, the shell 1 is extended in a transverse direction so as to reduce the height of the shell 1 to match the height of the indoor skirting, thereby facilitating heating the bottom of the room.

[0048] In one embodiment of the present invention, please refer to Figures 4 to 6 , multiple electromagnetic coil assemblies 31 are arranged along the transverse direction. In this way, multiple electromagnetic coil assemblies 31 are arranged along the transverse direction to adapt to the shape of the shell 1 so that more electromagnetic coil assemblies 31 can be arranged in the shell 1.

[0049] It should be noted that when the housing 1 is extended transversely, the number of the heating elements 21 can be various, such as one or more, and the present invention does not limit this.

[0050] In one embodiment of the present invention, please refer to Figure 3 and Figure 4, multiple electromagnetic coil assemblies 31 are located on the lower side of the heating element 21. Since a heat sink is usually provided on the upper side of the heating element 21, the electromagnetic coil assembly 31 is provided on the lower side of the heating element 21. This not only allows the layout direction of the electromagnetic coil assembly 31 and the heating element 21 to be compatible with the gas flow direction, but also facilitates the subsequent installation of a heat sink. Furthermore, there are many ways to arrange the electromagnetic coil assembly 31 and the heating element 21. For example, the electromagnetic coil assembly 31 and the heating element 21 can be placed close to each other or at intervals. As long as the electromagnetic coil assembly 31 can perform electromagnetic heating on the heating element 21, the present invention does not limit this.

[0051] It should be noted that the above two related technical features: "the plurality of electromagnetic coil assemblies 31 are arranged along the horizontal direction" and "the plurality of electromagnetic coil assemblies 31 are located on the lower side of the heating element 21" can be set one by one or at the same time. Obviously, setting them at the same time will have a better effect.

[0052] There are multiple ways for the at least two electromagnetic heating coil assemblies 31 to heat the heating element. In one embodiment, the heating element 21 is arranged in the up and down directions, and the at least two electromagnetic heating assemblies 31 are distributed in the up and down directions and are correspondingly arranged on one side of the horizontal direction of the heating element 21, so as to heat different upper and lower positions of the heating element 21 respectively, so that the at least two electromagnetic heating assemblies 31 can heat the same heating element, thereby helping to increase the heat generation of the heating element 21.

[0053] In another embodiment, the heating element 21 is set to at least two, and at least two of the heating elements 21 are distributed up and down, and the at least two electromagnetic heating components 31 are distributed up and down, and are correspondingly arranged on one side of the horizontal direction of the multiple heating elements 21 to heat each of the heating elements 21 separately, so that the electromagnetic heating component 31 only heats the corresponding heating element 21, so that the temperature distribution of the heater 100 in the up and down directions can be adjusted by turning on different numbers or positions of the electromagnetic coil components 31.

[0054] It should be noted that in some scenarios, when the lower part of the heater 100 needs to be heated, such as when the feet are cold, it is only necessary to turn on the electromagnetic heating component 31 at the lower part to heat the heating element 21 at the lower part. Similarly, when the upper part of the heater 100 needs to be heated, such as when the hands are cold, it is only necessary to turn on the electromagnetic heating component 31 at the upper part to heat the heating element 21 at the upper part. In this way, by turning on the electromagnetic heating components 31 at different positions, the upper and / or lower part of the heater 100 can be heated to meet the different needs of users, thereby helping to improve the user experience.

[0055] In one embodiment of the present invention, the shell 1 is extended in an elongated shape along the upper and lower parts, and the through holes 11 are provided in a plurality, and the plurality of through holes 11 include an air outlet through hole provided on one side of the shell 1, and an air inlet through hole staggered with the air outlet through hole. The air inlet through holes are arranged in the upper and lower directions, and a fan capable of blowing air toward the air outlet through hole is provided in the shell 1. In this way, by arranging the air outlet through hole toward the front side, the heater 100 can discharge air in a horizontal direction, and at the same time, the air outlet through hole is staggered with the air inlet through hole so as to prolong the retention time of the air in the shell 1, so that the heating The component 21 can fully exchange heat with the air in the shell 1, which helps to improve the heating effect of the heating component 21. At the same time, the air outlet holes are arranged in the up and down directions so that the temperature field of the heater 100 can be distributed in the up and down directions to meet the heating needs of different heights. In addition, since hot air generally flows upward, but the air outlet holes are arranged on the side of the shell 1, the hot air in the shell 1 is not easy to flow out of the shell 1. Therefore, a fan is provided to drive the hot air in the shell 1 to flow, so as to prevent heat from accumulating in the shell 1, thereby helping to improve the heating effect of the heater.

[0056] Furthermore, the heating element 21 can be provided in one or in multiple forms, and the present invention does not limit this. Specifically, in this embodiment, multiple heating elements 21 are distributed in the upper and lower directions. In this way, by providing multiple heating elements 21, the volume of a single heating element 21 can be reduced, which is convenient for both manufacturing and installation.

[0057] In one embodiment of the present invention, the heater 100 also includes a humidifying water tank (not shown in the figure) provided on the shell 1, and the electromagnetic heating structure also includes a humidifying heating element 21 for heating the water in the humidifying water tank, and at least one of the multiple electromagnetic coil assemblies 31 is used to electromagnetically heat the humidifying heating element 21. In this way, the humidifying water tank is set to store water, and the electromagnetic coil assembly 31 is set to electromagnetically heat the humidifying heating element 21 so that the humidifying heating element 21 generates heat, and the humidifying heating element 21 is set to heat the water in the humidifying water tank so that the water is vaporized into water vapor, thereby increasing the indoor air humidity.

[0058] Furthermore, there are many locations for setting the humidifying water tank. The humidifying water tank can be set inside the shell 1 or outside the shell 1, etc. The present invention does not limit this. Specifically, in this embodiment, the humidifying water tank is set inside the shell 1 so that the humidifying water tank can be hidden inside the shell 1, thereby helping to improve the appearance of the heater 100.

[0059] In one embodiment of the present invention, the shell 1 is extended in a transverse direction and is provided in a plurality of through holes 11, and the plurality of through holes 11 include an air inlet through hole provided at the bottom of the shell 1 and an air outlet through hole provided at the top of the shell 1. The humidifying water tank is provided near one end of the shell 1 in the transverse direction, and a plurality of the electromagnetic coil assemblies 31 are located on the lower side of the heating element 21 and the humidifying water tank. In this way, the humidifying water tank is provided near one end of the shell 1 in the transverse direction so that the heating water tank and the heating element 21 are arranged in the transverse direction so as not to affect the air flow in the shell 1. At the same time, the electromagnetic coil assembly 31 is provided on the lower side of the heating element 21 and the humidifying water tank so as to electromagnetically heat the heating element 21 and the humidifying heating element 21.

[0060] In one embodiment of the present invention, the humidifying and heating element 21 is disposed in the humidifying water tank so that the humidifying and heating element 21 can directly heat the water in the humidifying water tank, thereby accelerating the vaporization rate of the water in the humidifying water tank, thereby helping to improve the humidification effect of the humidifying and heating element 21. Of course, there are many ways to dispose the humidifying and heating element 21. In other embodiments, the humidifying and heating element 21 can also be disposed outside the humidifying water tank. As long as the humidifying and heating element 21 can heat the water in the humidifying water tank, the present invention does not limit this.

[0061] It should be noted that the above two related technical features: "The humidifying water tank is arranged at one end of the shell 1 in the horizontal direction, and the multiple electromagnetic coil assemblies 31 are located on the lower side of the heating element 21 and the humidifying water tank", and "The humidifying heating element 21 is arranged in the humidifying water tank" can be set one by one or at the same time, and the present utility model does not limit this.

[0062] In one embodiment of the present invention, please refer to Figure 3 The electromagnetic heating structure 3 includes a long bracket with a long setting, and multiple electromagnetic coil assemblies 31 are set on the long bracket. In this way, by setting the long bracket to adapt to the shape of the shell 1, so as to be installed on multiple electromagnetic coil assemblies 31, so as to assemble multiple electromagnetic coil assemblies 31 together, thereby facilitating the rapid installation of the electromagnetic coil assemblies 31.

[0063] In one embodiment of the present invention, the electromagnetic heating structure 3 includes a plurality of bracket units 32, and a plurality of the electromagnetic coil assemblies 31 are correspondingly arranged on the plurality of bracket units 32. Thus, by setting a plurality of the bracket units 32, a plurality of the electromagnetic coil assemblies 31 can be respectively installed so that the plurality of the electromagnetic coil assemblies 31 are independent of each other, thereby facilitating adjustment of the spacing between two adjacent electromagnetic coil assemblies 31 as needed.

[0064] In one embodiment of the present invention, please refer to Figures 3 to 6 The heating element 21 includes a heating body 211 and heat dissipation fins 212 in thermal contact with the heating body 211. At least one electromagnetic coil assembly 31 is used to electromagnetically heat the heating body 211. In this way, by setting the heating body 211, the electromagnetic coil assembly 31 can electromagnetically heat the heating element 21. At the same time, by setting the heat dissipation fins 212, the heat dissipation area of the heating element 21 can be expanded, so that the heating element 21 can quickly heat the air in the shell 1, thereby helping to improve the heating efficiency of the heater 100.

[0065] In one embodiment of the present invention, the electromagnetic coil assembly 31 includes a coil winding and a magnet arranged on the side of the coil winding facing away from the heating element 21. In this way, by setting the coil winding, the electromagnetic coil assembly 31 can electromagnetically heat the heating element 21. At the same time, by setting the magnet, on the one hand, the magnetic field strength of the coil winding can be enhanced, which is beneficial to increase the heating value of the heating element 21. On the other hand, the magnetic field of the coil winding can be constrained so that the magnetic field converges toward the heating element 21 to prevent the magnetic field from spreading outside the shell 1, thereby reducing the electromagnetic impact of the heater 100 on the surrounding environment.

[0066] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
