[0033] The following Figures 1 to 4 and through specific embodiments to further illustrate the technical solutions of the present utility model.

[0034] An electric heater using a new type of heating element, comprising a housing, a plurality of new type of heating elements 2, a control component 3, and a thermal protection component 4;

[0035] The interior of the housing has a receiving cavity 10. An air inlet 101 is provided at the bottom of the housing, and an air outlet 102 is provided at the top of the housing. The air inlet 101 and the air outlet 102 communicate with the receiving cavity 10;

[0036] A plurality of the new type of heating elements 2 are arranged and installed vertically in the receiving cavity 10. The new type of heating element 2 includes a non-light-emitting heating element 21, a radiation part 22, and a convection part 23. The radiation part 22 and the convection part 23 are respectively arranged oppositely up and down with the non-light-emitting heating element 21 as the axis;

[0037] The new type of heating element 2 is connected to the control component 3 and the thermal protection component 4.

[0038] Reference Figures 1 to 2, the electric heater of the present utility model is provided with a new type of heating element, and its working principle is as follows: A number of new type of heating elements are installed vertically inside the accommodating cavity 10. Air enters the accommodating cavity 10 from the air inlet 101 at the bottom of the housing, passes through multiple new type of heating elements 2 from bottom to top, and then is discharged from the air outlet 102 at the top of the housing and diffused; Among them, the new type of heating element 2 includes a non-light-emitting heating element 21, a radiation part 22 and a convection part 23. The radiation part 22 conducts the heat generated by the non-light-emitting heating element 21 along the extending direction of the radiation part 22, and the convection part 23 conducts the heat generated by the non-light-emitting heating element 21 along the extending direction of the convection part 23. The combination of these two heat conduction modes forms the new type of heating element 2 of the present utility model, which can make full use of the advantages of both. On the one hand, far-infrared radiation heating is realized through the radiation part 22, which directly acts on the human body or the surface of an object, improving the pertinence and efficiency of heating, enabling the entire room to be evenly heated, and avoiding problems such as single-point overheating or uneven heating; On the other hand, the design of the convection part 23 promotes the natural convection of warm air in the accommodating cavity 10, making the heat more evenly distributed throughout the room and improving the heating effect; Further, the heating element uses a non-light-emitting heating element 21, so that the non-light-emitting heating element 21 does not generate visible light during the heating process, and the radiation part 22 and the convection part 23 transfer heat to the surrounding environment or object through heat radiation, heat conduction or heat convection, etc.; Even further, since the present utility model omits the fan part in the traditional heater, or even if it includes a fan, it may adopt a more advanced low-noise design, the noise generated during use will be significantly reduced. This is particularly important for occasions where it is necessary to use in a quiet environment (such as bedrooms, libraries, etc.), and can greatly improve the comfort of users. The convection part 23 utilizes natural convection heat transfer of air, has no problem of warm near and cold far, has high safety performance, operates without noise, does not generate a sense of wind, and brings a quiet and comfortable experience. Therefore, the electric heater of the present utility model has the advantages of being silent and non-light-emitting, fast heat conversion, rapid temperature rise, good infrared emission effect, and far heat energy radiation distance, avoiding the problems of glowing and shining at night, affecting rest and sleep, and having potential safety hazards.

[0039] In summary, this technical solution significantly improves the safety, comfort, heating efficiency, energy saving and aesthetics of the electric heater by introducing a new type of heating element, providing users with a more high-quality and efficient heating experience.

[0040] Preferably, the non-light-emitting heating element 21 can adopt a ceramic heating tube or a carbon fiber heating tube.

[0041] Further, the housing includes a front shell 11 and a rear shell 12, and the air inlet 101 and the air outlet 102 are provided at the bottom and top of the rear shell 12;

[0042] The new type of heating element 2 is installed on the rear shell 12 through a mounting bracket 5;

[0043] The radiation part 22 is close to the front shell 11, and the convection part 23 is close to the rear shell 12.

[0044] By arranging the air inlet 101 and the air outlet 102 at the bottom and top of the rear shell 12, this design helps to optimize the air flow path. Cold air enters from the bottom, is heated by the new heating element 2, and then the hot air naturally rises and is discharged from the top, forming a smoother and more efficient air convection cycle. This design not only improves the heating efficiency but also makes the heat distribution more uniform.

[0045] The new heating element 2 is installed on the rear shell 12 through the mounting bracket 5, which makes the installation and disassembly of the heating element more convenient. When cleaning, repairing or replacing the heating element is needed, users can easily complete these operations without disassembling the whole electric heater.

[0046] Setting the radiation part 22 close to the front shell 11 enables the far-infrared radiation to act more directly on the users or objects in front of the electric heater, reducing the heat loss and transfer path, thereby improving the efficiency and effect of the thermal radiation heating. This is particularly important for users who need to feel warm quickly. Setting the convection part 23 close to the rear shell 12 helps to better transfer the heat generated by the heating element to the surrounding air and discharge it through the air outlet. At the same time, as the back support structure of the electric heater, the rear shell also provides additional protection for the convection part 23, preventing users from directly contacting high-temperature components and increasing the safety of use.

[0047] Furthermore, the radiation part 22 includes two flat radiation fins 221 arranged symmetrically up and down. The two radiation fins 221 are respectively connected to the non-light-emitting heating element 21 and extend along the vertical direction, and the surfaces of the radiation fins 221 are attached with graphite or graphene coatings.

[0048] The radiation part 22 is designed as two flat radiation fins 221 arranged symmetrically up and down. This structure increases the radiation area, enabling the far-infrared rays to radiate more widely into the surrounding space. At the same time, the graphite or graphene coatings attached to the surfaces of the radiation fins 221 have excellent heat conduction performance and far-infrared radiation performance, which can further improve the thermal radiation efficiency. This means that the electric heater can reach the set temperature in a shorter time, and the heat distribution is more uniform, enhancing the heating effect and user experience.

[0049] It is worth noting that as efficient heat conduction materials, graphite and graphene can quickly transfer the heat generated by the non-light-emitting heating element 21 to the radiation fins 221 and radiate it out through far-infrared rays. This efficient electro-thermal conversion process reduces energy loss and improves the overall energy efficiency ratio of the electric heater. In the long run, this helps to reduce the heating cost of users and conforms to the environmental protection concept of energy conservation and emission reduction.

[0050] Further, a plurality of reinforcing ribs 2211 are provided on both sides of the radiation fin 221, and the plurality of reinforcing ribs 2211 are parallel to each other and extend along the length direction of the radiation fin 221.

[0051] The addition of the reinforcing ribs 2211 enhances the structural rigidity of the radiation fin 221 on the one hand. As a key component for heat generation and dissipation, the radiation fin 221 will bear certain thermal stress and mechanical stress. Therefore, the design of the parallel and lengthwise extension of the reinforcing ribs 2211 enables the radiation fin to better resist deformation and maintain a stable shape when stressed. On the other hand, the presence of the reinforcing ribs 2211 makes the overall structure of the radiation fin 221 more compact and orderly. The design of the reinforcing ribs 2211 helps to guide the flow of air on the surface of the radiation fin 221, enabling heat to be radiated and distributed more evenly outward, indirectly increasing the effective heat dissipation area of the radiation fin 221 and allowing heat to be dissipated to the surrounding environment more quickly.

[0052] Further, the convection part 23 includes two convection fins 231 symmetrically arranged up and down, and the two convection fins 231 are respectively connected to the non-light-emitting heating element 21 and extend in the vertical direction.

[0053] The convection part 23 is designed as two convection fins 231 symmetrically arranged up and down. The design of the convection fins 231 increases the heat exchange area between the heating body and the air, enabling heat to be transferred to the surrounding air more quickly. At the same time, the vertical extension of the convection fins 231 also promotes the rise of hot air and the replenishment of cold air, forming a continuous heat convection cycle. This enhanced heat dissipation effect helps to reduce the temperature of the heating body, extend its service life, and reduce potential safety hazards caused by overheating.

[0054] For further illustration, as Figure 3 and Figure 4 shown, the convection fins 231 and the radiation fins 221 are arranged at intervals, and they jointly act on the air in the accommodation cavity 10 to form a multi-dimensional heating effect. The radiation fins 221 directly heat the objects and human bodies in front through far-infrared radiation, while the convection fins 231 evenly distribute the heat to the entire room by promoting air convection. This combined heating method makes the heating effect of the electric heater more uniform, avoiding local overheating or overcooling phenomena.

[0055] Further, a plurality of convection holes 2311 are formed at equal intervals along the length direction of the convection fin 231, and the plurality of convection holes 2311 penetrate through the convection fin 231.

[0056] A number of convection holes 2311 are evenly spaced along the length direction of the convection fins 231, significantly enhancing the air circulation between the convection fins 231. These convection holes 2311 enable cold air to penetrate more deeply into the interior of the convection fins, conduct more sufficient heat exchange with the heat generated by the non-light-emitting heating element 21, and then the heated hot air quickly rises and is discharged through the convection holes 2311. This design not only improves the heat transfer efficiency but also makes the air convection more uniform and rapid, thus enhancing the heating effect of the electric heater.

[0057] Furthermore, one side of the convection hole 2311 is provided with a convection flange 2312, the convection flange 2312 is arranged on the side away from the radiation fin 221, and a number of the convection flanges 2312 are parallel to each other.

[0058] The convection flanges 2312 are arranged on one side of the convection holes 2311, and these convection flanges 2312 are parallel to each other and arranged on the side away from the radiation fins 221. Such a design can more effectively guide the air flow. The convection flanges 2312, as the air flow guiding structure, can enable the cold air entering the convection fins 231 to be guided to a certain extent when passing through the convection holes, so as to flow more smoothly along the length direction of the convection fins and conduct more sufficient heat exchange with the heat generated by the non-light-emitting heating tube. This enhanced air directivity helps to improve the heat transfer efficiency and heating effect.

[0059] The design of the convection flanges 2312 not only enhances the air convection effect but also further improves the heating uniformity. Since the convection flanges 2312 can guide the air to be more evenly distributed between the convection fins 231, the heated hot air can also be discharged more evenly through the air outlet and diffused throughout the room. This uniform heating method avoids the phenomenon of local overheating or overcooling and improves the comfort of users.

[0060] Furthermore, the vertical section of the new heating element 2 is in an X shape.

[0061] The X-shaped design makes the heating element form more surface area in the vertical section, thus increasing the contact area with the air. This design is beneficial to transfer heat to the surrounding air faster and improves the heat dissipation efficiency. At the same time, the X-shaped structure may also form more convection channels inside to promote the natural convection of air and further enhance the heat dissipation effect.

[0062] Furthermore, the front shell 11 is provided with a number of heat dissipation holes 103 communicating with the accommodation cavity 10, and the positions of a number of the heat dissipation holes 103 correspond to those of the radiation part 22.

[0063] The provision of the heat dissipation holes 103 enables the heat within the accommodation cavity 10 to be dissipated more directly and rapidly to the external environment through the front shell 11. Especially when the positions of the heat dissipation holes 103 correspond to those of the radiation part 22, the heat generated by the radiation part 22 can be directly discharged through the corresponding heat dissipation holes 103, thereby enhancing the heat dissipation efficiency. This design helps to reduce the temperature inside the electric heater, extend the service life of the heating element, and reduce potential safety hazards caused by overheating.

[0064] Further elaborating, since the positions of the heat dissipation holes 103 correspond to those of the radiation part 22, the far-infrared rays generated by the radiation part 22 can irradiate more directly the area around the heat dissipation holes 103. This design helps to reduce heat loss during the heat transfer process, making the heating effect more uniform. Meanwhile, the arrangement of the heat dissipation holes 103 can also be adjusted according to the actual layout of the room and the heating requirements to achieve the best heating effect.

[0065] Even further, two supporting feet are detachably provided at the bottom of the housing 1, and a wall hanging bracket 7 is also provided at the back of the housing 1;

[0066] The supporting feet include a foot bracket 61 and a foot 62. The foot bracket 61 includes a vertical mounting portion 611 and a horizontal mounting portion 612. The vertical mounting portion 611 and the horizontal mounting portion 612 are perpendicular to each other. The vertical mounting portion 611 is mounted and connected to the outside of the rear shell 12, and the horizontal mounting portion 612 is mounted and connected to the top of the foot 62.

[0067] By mounting and connecting the vertical mounting portion 611 of the foot bracket 61 to the outside of the rear shell 12 and the horizontal mounting portion 612 to the top of the foot 62, a stable supporting structure is formed. This design makes the electric heater more stable when placed and not prone to tipping over, thereby enhancing the safety during use. The foot 62 is usually designed as a component with an anti-slip function, such as a rubber pad, etc., which further enhances the stability of the electric heater on the ground and prevents slipping or tipping over caused by a wet or uneven ground.

[0068] Further, a wall hanging bracket 7 is also provided at the back of the housing. The wall hanging bracket 7 is provided with a plurality of mounting holes. Through the mounting holes, the present utility model can be mounted on a wall or other places where fixed installation is required. Specifically, corresponding mounting openings are formed on the wall, and an anchoring structure such as a nut and bolt is used to mount and fix the device on the wall. By mounting the present utility model on the wall instead of placing it on the ground, the occupied space can be reduced.

[0069] The technical principle of the present utility model has been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present utility model and cannot be construed as a limitation on the protection scope of the present utility model in any way. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present utility model without creative efforts, and these embodiments will fall within the protection scope of the present utility model.
