Technical Field
[0001] This utility model relates to the field of heater structure technology, and in particular to a heater. Background Technology
[0002] Electromagnetic induction heating is a mature and widely used heating technology in household appliances and industrial fields. Its heating principle involves a high-frequency changing current flowing through a coil to generate a high-frequency changing magnetic field.

Besides the main part that heats the heating element, some magnetic field still escapes, resulting in energy waste and potentially affecting the normal operation of electronic components. Therefore, a structural solution is urgently needed to address these problems in electromagnetic heating heaters. Utility Model Content

The air entering the shell is heated by the heating element and then flows out of the shell, that is, the heat generated by the heating element is carried out of the shell, thus achieving the heating function of the heater. Compared to traditional structures where heat pipes must come into contact with the heating element to transfer heat to it before heat exchange with the air, the electromagnetic heating coil assembly in this application heats the heating element without contact, as the heating element is the primary medium for heat exchange with the air.

[0049] Electromagnetic induction heating is a mature and widely used heating technology in household appliances and industrial fields. Its heating principle involves a high-frequency changing current flowing through a coil to generate a high-frequency changing magnetic field. Eddy currents are generated in the heating element through the coupling surface, and according to the Joule heating effect, the heating element heats up. However, it's understandable that the high-frequency changing magnetic field generated by the current flowing through the coil disperses in all directions. Besides the main part that heats the heating element, some magnetic field still escapes, resulting in energy waste and potentially affecting the normal operation of electronic components. Therefore, a structural solution is urgently needed to address these problems in electromagnetic heating heaters.
[0050] This utility model proposes a heater; please refer to [link / reference]. Figures 1 to 3 The following is an embodiment of the heater proposed in this application, and the heater will be described in detail below with reference to the specific drawings.
[0051] Please see Figures 1 to 3 The heater 100 includes a housing 1, a heating element 2, and an electromagnetic heating structure 3. The housing 1 is provided with a through hole 11 to allow air exchange with the outside of the housing 1. The heating element 2 is disposed in the housing 1. The electromagnetic heating structure 3 includes an electromagnetic heating coil assembly 31 disposed in the housing 1, which is used to electromagnetically heat the heating element 2. The housing 1 has at least one heat insulation plate 12 formed on the periphery corresponding to the heating element 2, and the heat insulation plate 12 can be electromagnetically heated by the electromagnetic heating coil assembly 31.
[0052] In the technical solution of this utility model, the heater 100 is composed of the housing 1, the heating element 2, and the electromagnetic heating structure 3. Specifically, the heating element 2 and the electromagnetic heating structure 3 are built into the housing 1. The electromagnetic heating structure 3 includes an electromagnetic heating coil assembly 31 for heating the heating element 2, so that after the electromagnetic heating coil assembly 31 is energized, it can generate an alternating magnetic field around the heating element 2. The heating element 2 is placed in this alternating magnetic field and cuts the magnetic field, causing it to heat up. The housing 1 has a through hole 11 so that the air outside the housing 1 can exchange with the air inside the housing 1 through the through hole 11. The air entering the housing 1 is heated by the heating element 2 and then flows out of the housing 1, that is, the heat generated by the heating element 2 is carried out of the housing 1, thus achieving the heating function of the heater 100. Compared to traditional structures where heat pipes must come into contact with the heating element 2 to transfer heat to it before heat exchange with the air, the electromagnetic heating coil assembly 31 in this application heats the heating element 2 without contact, as the heating element 2 is the primary medium for heat exchange with the air. This results in higher heating efficiency and utilization of the heating element 2. Furthermore, the electromagnetic heating coil assembly 31 allows for stepless adjustment of its heating power, leading to higher thermal efficiency, more flexible temperature control, and greater economy and practicality for the heater 100. In addition, the heating element 2 is surrounded by a heat insulation plate 12. This heat insulation plate 12 serves two purposes: firstly, it isolates the heat emitted by the heating element 2, reducing the temperature of its outer periphery and inner side; secondly, it is electromagnetically heated by the electromagnetic heating coil assembly 31, consuming some power to provide auxiliary heating; and thirdly, while consuming the heating power of the electromagnetic heating coil assembly 31, it reduces magnetic field leakage, minimizing the impact on external electrical components.
[0053] Specifically, multiple through holes 11 are provided, including an air inlet through hole 112 located at the upper end of the housing 1 and an air outlet through hole 111 located at the lower end of the housing 1. The main function of the through holes 11 is to connect the air environment inside and outside the housing 1, so that the air inside and outside the housing 1 can circulate, and the heat on the heating element 2 located inside the housing 1 can be carried away by the air as a medium, so as to heat the external environment of the housing 1, that is, the heating effect of the heater 100. Therefore, the specific number and arrangement of the through holes 11 are not limited, as long as they can realize air exchange between the inside and outside of the housing 1. In this application, multiple through holes 11 are set to improve heat exchange efficiency. Based on this, it can be understood that the density of hot air is less than that of cold air. That is, after the cold air entering the housing 1 is heated by the heating element 2, its density decreases and it will move upward to form an airflow from bottom to top. Therefore, this application uses this principle to set multiple through holes 11 as the air outlet through hole 111 located at the upper end of the housing 1 and the air inlet through hole 112 located at the lower end of the housing 1, so as to realize the heating function of the heater 100 without adding an additional air drive device and meet the usage requirements.
[0054] Specifically, the air outlet 111 is located at the top of the housing 1; the air inlet 112 is located at the bottom of the housing 1. The through-hole 11 is divided into the air outlet through-hole 111 located at the upper end of the housing 1 and the air inlet through-hole 112 located at the lower end of the housing 1, as described above. Based on this, the air inlet through-hole 112 and the air outlet through-hole 111 can be set on the side wall of the housing 1, or on the top and bottom of the housing 1, without limitation, and can achieve the above-mentioned air flow function to meet the heating needs. In this embodiment, the air outlet through-hole 111 is set on the top of the housing 1 and the air inlet through-hole 112 is set on the bottom of the housing 1. On the one hand, no opening is made on the side wall of the housing 1, which has a good appearance effect. On the other hand, an air passage is formed inside the housing 1 for vertical airflow, and the air flow is less obstructed by the housing 1, which has a high air flow efficiency and a good air exchange effect, thereby improving the heating effect of the heater 100. Furthermore, the air inlet through-hole 112 is located at the bottom of the housing 1, which makes it less likely to suck in debris.
[0055] In addition, the shape of the heating element 2 is adapted to that of the electromagnetic heating coil assembly 31 to ensure the heating performance of the electromagnetic heating coil assembly 31 on the heating element 2.
[0056] Furthermore, the housing 1 extends laterally in an elongated shape. The shape of the housing 1 is not actually limited, but to suit the use scenario in a home, the elongated shape of the housing 1 extends laterally to facilitate the placement of the heater 100 and to provide a wider heating range.
[0057] Specifically, based on the shape of the housing 1, the structure of the electromagnetic heating coil assembly 31 and the heating element 2 disposed within the housing 1 is not actually limited, as long as they can be accommodated within the housing 1. However, in this embodiment, both the electromagnetic heating coil assembly 31 and the heating element 2 are arranged in a long shape extending laterally to adapt to the shape of the housing 1, thus ensuring greater heating efficiency and ensuring the effectiveness of use.
[0058] Specifically, the electromagnetic heating coil assembly 31 is arranged laterally; and / or, the electromagnetic heating coil assembly 31 is located below the heating element 2, or, the electromagnetic heating coil assembly 31 is located on the horizontally upward side of the heating element 2. Based on the elongated structural feature of the housing 1 extending laterally, the laterally arranged electromagnetic heating coil assembly 31 avoids the shape of the housing 1 limiting the size of the electromagnetic heating coil assembly 31, thereby ensuring the operating power of the electromagnetic heating coil assembly 31. Furthermore, the heating power of the electromagnetic heating coil assembly 31 on the heating element 2 is not only related to the operating power of the electromagnetic heating coil assembly 31 itself, but also to the relative position of the electromagnetic heating coil assembly 31 and the heating element 2. To maximize the heating power, this application proposes that the electromagnetic heating coil assembly 31 be located below the heating element 2 or on the horizontally upward side of the heating element 2. That is, in one embodiment proposed in this application, the electromagnetic heating coil assembly 31 is located below the heating element 2, and both extend horizontally; in another embodiment proposed in this application, the electromagnetic heating coil assembly 31 and the heating element 2 are both arranged laterally, and the electromagnetic heating coil assembly 31 is located on one side of the heating element 2 in the thickness direction of the housing 1. Thus, both embodiments ensure the heating power of the electromagnetic heating coil assembly 31 on the heating element 2. The specific arrangement depends on actual needs and is not limited here.
[0059] In addition, a heat insulation plate 12 is provided inside the housing 1, and the heat insulation plate 12 and the housing 1 together form a heat insulation cavity 13; the heater 100 also includes an electronic control component 4, and the electronic control component 4 includes at least one electrical device disposed in the heat insulation cavity 13. Generally, the electronic control component 4 cannot withstand high temperatures. Therefore, in some embodiments, the electronic control component 4 can be disposed on the outside of the housing 1 to detach from the inner cavity of the housing 1. However, this arrangement cannot prevent part of the structure of the electronic control component 4 from extending into the housing 1, and it also affects the appearance of the heater 100. Therefore, in this embodiment, the heat insulation plate 12 is disposed inside the housing 1 to form the heat insulation cavity 13 by the heat insulation plate 12 and the housing 1. This allows the electronic control component 4 to be disposed inside the heat insulation cavity 13 to avoid the high-temperature air inside the housing 1, so as to avoid the electronic control component 4 being damaged by heat. At the same time, it avoids the electronic control component 4 being disposed outside the housing 1 to avoid affecting the appearance of the heater 100, and also avoids the safety hazards caused by the external placement of the electrical components inside the electronic control component 4.
[0060] Furthermore, multiple through holes 11 are provided, including an air outlet through hole 111 located at the top of the housing 1 and an air inlet through hole 112 located at the bottom of the housing 1. The heat insulation plate 12 is correspondingly arranged with the side of the housing 1 to form the heat insulation cavity 13 together with the side of the housing 1. The air outlet through hole 111 located at the top of the housing 1 and the air inlet through hole 112 located at the bottom of the housing 1 have been described in detail above and will not be repeated here. Based on the location of the through holes 11, when the heat insulation plate 12 is correspondingly arranged with the side of the housing 1, the heat insulation plate 12 will not block the flow of air from the air inlet through hole 112 to the air outlet through hole 111. At the same time, because the airflow will not flow towards the heat insulation plate 12, the temperature inside the heat insulation cavity 13 is relatively lower, which can provide better high-temperature protection for the electronic control component 4.
[0061] Furthermore, the heat insulation plate 12 is correspondingly provided on the inner side of each side of the housing 1, so that the heat insulation cavity 13 is formed on the periphery of the heating element 2. The heat insulation plate 12 is mainly used to protect the electronic control component 4 from high temperature. In this embodiment, the heat insulation plate 12 is provided on the inner side of each side of the housing 1, so that the heat insulation cavity 13 is formed on the periphery of the heating element 2. That is to say, the heat insulation cavity 13 is evenly distributed on the inner periphery of the housing 1. In this way, on the one hand, it does not affect the airflow from bottom to top to achieve its heating function, and on the other hand, it prevents the housing 1 from being heated, so as to prevent the user from touching the heater 100 and being burned during the use of the heater 100. While ensuring the heating function of the heater 100, it also provides safety protection for the user.
[0062] Furthermore, a fan 5 is provided inside the heat insulation cavity 13, and an air inlet 14 is provided on the portion of the housing 1 corresponding to the heat insulation cavity 13. An air outlet 15 is provided on the top of the housing 1 or the heat insulation plate 12. To further improve the heat insulation capacity of the heat insulation cavity 13, the fan 5 is added inside the heat insulation cavity 13 based on the heat insulation plate 12, and the air inlet 14 is provided on the portion of the housing 1 corresponding to the heat insulation cavity 13. At the same time, the air outlet 15 is provided on the top of the heat insulation plate 12 or the housing 1. The fan 5 drives the gas flow in the heat insulation cavity 13 to draw low-temperature air from outside the housing 1 into the heat insulation cavity 13 and drive the higher-temperature air in the heat insulation cavity 13 to be blown out from the air outlet 15. It is understood that the location of the air inlet 14 is not limited here, since the fan 5 is installed here. The fan 5 drives the air flow, and the opening can be made at any position on the housing 1 to draw cold air from outside the housing 1 into the heat insulation cavity 13. Of course, it is more effective to place the air inlet 14 at the lower part of the housing 1. The air outlet 15 is set at the top of the housing 1 or on the heat insulation plate 12, that is, the air outlet 15 is opened along the natural flow direction of the higher temperature air, which makes it easier for the higher temperature air to flow out of the heat insulation cavity 13, thereby reducing the working power of the fan 5, reducing energy consumption and even reducing the noise of the fan 5.
[0063] Furthermore, compared to the aforementioned embodiment that avoids heating the housing 1 to ensure user safety, in this embodiment, the heat insulation plate 12 includes a metal plate disposed on the inner side of the housing 1; and / or, at least a portion of the wall of the housing 1 is made of metal to form the heat insulation plate 12. Unlike the consideration of user safety, this embodiment primarily considers the heating effect of the heater 100, while also meeting other user heating needs. Specifically, unlike air heating, the heating needs are mainly achieved by the heat insulation plate 12 on the side of the housing 1 cutting through the magnetic field generated by the electromagnetic heating coil assembly 31, thereby causing it to heat up. This results in the housing 1 in this embodiment heating up at the position corresponding to the heat insulation plate 12, thus satisfying some heating needs. It is understandable that, to meet different heating needs, the heat insulation plate 12 can be an exposed part of the housing 1. That is, it can be the heat insulation plate 12 disposed on the outer side of the housing 1, the heat insulation plate 12 embedded in the housing 1, or the heat insulation plate 12 disposed on the inner side wall of the housing 1. It is even possible to make the housing 1 out of metal so that the housing 1 can serve as the heat insulation plate. All of these can meet the heating requirements. However, even if the housing 1 needs to generate heat laterally to meet different heating needs, it is still necessary to consider The safety of the heater 100 is addressed in this embodiment, where the side of the housing 1 includes the main body and the heat insulation plate 12. The heat insulation plate 12 is disposed on the inner side wall of the housing 1 or only a portion of the housing 1 is made of metal to form the heat insulation plate 12. After the heat insulation plate 12 is heated by the electromagnetic heating coil assembly 31, it transfers heat to the housing 1 so that the heating of the side of the housing 1 can be met by the heating of the housing 1, thus avoiding direct contact between the user and the heat insulation plate 12 and achieving a safety protection effect.
[0064] Furthermore, the electromagnetic heating coil assembly 31 is disposed on one side of the heating element 2; the electromagnetic heating structure 3 also includes a magnet structure 32 disposed on the side of the electromagnetic heating coil assembly 31 opposite to the heating element 2. The magnetic field generated by the electromagnetic heating coil assembly 31 is in the form of radiating in all directions, while the heating element 2 can only be disposed on a portion of the side of the electromagnetic heating coil assembly 31. To improve the heating efficiency and energy efficiency of the electromagnetic heating coil assembly 31, in this embodiment, the magnet structure 32 is disposed on the side of the electromagnetic heating coil assembly 31 opposite to the heating element 2, so that the magnetic force of the magnet structure 32 attracts the magnetic field generated by the electromagnetic heating coil assembly 31, giving a focusing effect on 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. Meanwhile, the edges of the concentrated magnetic field are absorbed by the heat insulation plate 12, further enhancing the concentration of the magnetic field and preventing magnetic field leakage. The heat insulation plate 12 can also serve as an auxiliary heating element to assist the heating element 2 in heating up, without causing the shell 1 to overheat, thus further meeting the requirements.
[0065] Furthermore, the heating element 2 includes a heating body 21 and fins 22 thermally connected to the heating body 21; the electromagnetic heating coil assembly 31 is used to electromagnetically heat the heating body 21. It is understood that the heat exchange efficiency between the heating element 2 and the air is related to the contact area between the heating element 2 and the air. Therefore, to improve the heat dissipation efficiency of the heating element 2 and thus enhance the heating performance of the heater 100, in this embodiment, the heating element 2 is configured as a combination of the heating body 21 and the fins 22, with the fins 22 thermally connected to the heating body 21. The electromagnetic heating coil assembly 31 is used to electromagnetically heat the heating body 21, and the heat on the heating body 21 can be conducted to the fins 22. Thus, through the contact between the fins 22 and the air, the heat exchange area between the heating element 2 and the air is significantly increased, thereby improving the heating performance of the heater 100.
[0066] Furthermore, the fins 22 and the heating element 21 are integrally formed, or the fins 22 and the heating element 21 are separately formed. The specific arrangement of the fins 22 and the heating element 21 is not limited; that is, the fins 22 can be integrally formed with the heating element 21, or they can be independently formed and then combined and fixed using other heat-conducting fixing methods, as long as the heat from the heating element 21 can be conducted to the fins 22.
[0067] Furthermore, multiple electromagnetic heating coil assemblies 31 are configured to electromagnetically heat one of the heating elements 2; alternatively, multiple electromagnetic heating coil assemblies 31 and multiple heating elements 2 are configured, with each set corresponding to a specific heating element 2. At least some of these multiple electromagnetic heating assemblies are arranged in parallel to allow for independent control. While ensuring the electromagnetic heating coil assemblies 31 function to heat the heating elements 2, the number of electromagnetic heating coil assemblies 31 and the number of heating elements 2 are not limited. Multiple electromagnetic heating coil assemblies 31 can electromagnetically heat one heating element 2; or multiple electromagnetic heating coil assemblies 31 can electromagnetically heat multiple heating elements 2. The number of components can be the same or different, as long as the heating function is achieved. As for controlling the multiple electromagnetic heating coil components 31, they can be connected in series to enable them to turn on and off synchronously, thereby improving heating efficiency. However, this does not enable individual control of their on / off states. Therefore, in this embodiment, the multiple electromagnetic heating components are connected in parallel so that they can all be controlled independently, thereby providing the heater 100 with more heating power levels to meet the needs of more heating power level adjustments.
[0068] Furthermore, this utility model also proposes a heater 100. Specifically, the heater 100 in this embodiment includes a housing 1, a heating element 2, and an electromagnetic heating structure 3. The housing 1 is provided with a through hole 11 to allow exchange with the air outside the housing 1. The heating element 2 is disposed in the housing 1. The electromagnetic heating structure 3 includes an electromagnetic heating coil assembly 31 disposed in the housing 1, and the electromagnetic heating coil assembly 31 is located above or below the heating element 2. The electromagnetic heating coil assembly 31 is used to electromagnetically heat the heating element 2. The heating element 2 is heated by the electromagnetic heating coil assembly 31, as described in detail in other embodiments above, and will not be repeated here. Here, we mainly present two distribution forms of the heating element 2 and the electromagnetic heating coil assembly 31. In some embodiments, the electromagnetic heating coil assembly 31 is located on the lower side of the heating element 2, and in other embodiments, the electromagnetic heating coil assembly 31 is located on the upper side of the heating element 2. Both can satisfy the heating function of the heater 100 for normal use by the user.
