[0038] The present application discloses a heating component and a heating device. The heating component, as a component in the heating device, is mainly used for heating the outlet air, realizing the function of the heating device to discharge hot air. The definition of the heating device is not limited to a certain device. The heating device described in the present application can mainly realize the supply of hot air. It can be understood that the heating device at least includes an air outlet device and a heating component, and the air outlet of the air outlet device is heated by the heating component to form hot air for discharge. For example, commonly used air conditioners, air conditioners, dryers, and other equipment with warm air supply function.

[0039] The heating components are explained in detail below.

[0040] The heating component includes a frame, a support member, a heating belt, and a vibration damping member. Different shapes of heating components have different structures. The following specific examples describe rectangular and annular heating components, but the structure protected by this application is not limited to the above two shapes.

[0041] See also Figures 1 to 3 , discloses a schematic structural diagram of a rectangular heating component 10. The heating component 10 includes a frame 100, which is composed of multiple frame edges on the top, bottom, left, and right sides. Multiple support members 200 are disposed within the frame 100. As can be seen from the figure, the support members 200 are installed in the frame 100 in a sequentially spaced manner from left to right. The support members 200 are provided with belt slots 310 for mounting the heating belt 300. The material of the support members 200 is preferably an insulating material, such as mica sheets.

[0042] The heat-generating belt 300 is arranged such that it passes through the belt slot 310 from one end of the frame 100, extends toward the other end, and is supported on the support member 200. Preferably, the heat-generating belt 300 can be wound from one end of the frame 100 toward the other end and then back again, wrapping around multiple support members 200 from top to bottom and from left to right. Furthermore, because the heat-generating belt 300 is wound around multiple support members 200 in multiple directions, the portion of the heat-generating belt 300 between two adjacent support members 200 is considered a heat-generating segment. A vibration damper 400 is provided on each heat-generating segment. If the heat-generating segment has only one segment, the vibration damper 400 is provided on that segment. If the heat-generating segment has multiple segments, the vibration damper 400 can be provided on some or all of the segments. The structure of the vibration damper 400 is not limited and can be fixed to any portion of the heat-generating segment, cover certain portions of the segment, or cover all of the segment. One or more vibration dampers 400 can be provided on the heating section; when multiple vibration dampers are provided, they can be provided continuously or at intervals, and the intervals are preferably provided near both ends of the heating belt.

[0043] See also Figure 6 and Figure 7 , discloses a structural schematic diagram of a ring-shaped heating component 10. It also includes a frame 100, which is ring-shaped and includes an inner ring and an outer ring. A plurality of support members 200 are arranged between the inner ring and the outer ring, and the support members 200 are distributed at intervals along the ring. The heating belt 300 passes through the belt groove 310 on the support member 200 in sequence for placement. The material of the support member 200 is preferably an insulating and heat-insulating material, such as mica sheet. The area of the heating section and the setting method of the vibration damping member 400 can refer to the example of the rectangular heating component 10, and will not be repeated here. The following content is explained using the rectangular heating component 10.

[0044] When the heating element 10 is operating, heat is generated through the heat-generating belt 300, which then cooperates with the air outlet device to discharge hot air. Specifically, the heat-generating belt 300 is placed in the air outlet duct of the air outlet device, thereby heating the outlet air and achieving hot air discharge. However, due to the thinness and light weight of the heat-generating belt 300, it is easily vibrated and noisy under the impact of the outlet airflow. Therefore, by adding a vibration damping member 400 to the heating section, while ensuring that its resistance is not changed, the stiffness of the heating section is appropriately increased, its natural frequency is raised, or its damping is increased, thereby reducing vibration and effectively reducing the generation of noise.

[0045] Optionally, in order to avoid affecting the resistance of the heat-generating belt 300, the vibration damper 400 is preferably made of an insulating heat-conducting material, such as mica, ceramic, or polyimide.

[0046] Optionally, see Figures 3 to 4b, the vibration damper 400 includes a first insulating heat-conducting layer 410, and the first insulating heat-conducting layer 410 is attached to a surface of the heat-generating belt 300 along the length direction of the heat-generating section. The first insulating heat-conducting layer 410 and the heat-generating belt 300 can be attached by bonding (high-temperature resistant glue) or fixed by fixing members (such as binding, clamping or snap-fitting, etc.). The first insulating heat-conducting layer 410 can be attached to a partial area or the entire area of the heat-conducting section. Similarly, optionally, the vibration damper 400 also includes a second insulating heat-conducting layer 420, and the second insulating heat-conducting layer 420 is attached to the other surface of the heat-generating belt 300 relative to the first insulating heat-conducting layer 410 along the length direction of the heat-generating section. The setting method of the second insulating heat-conducting layer 420 can refer to the first insulating heat-conducting layer 410, and will not be repeated here. In this application, please refer to the specific Figure 4a and Figure 4b Preferably, the first insulating heat-conducting layer 410 and the second insulating heat-conducting layer 420 are fixed to the heat-generating belt 300 by a metal clip 500. The first insulating heat-conducting layer 410 and the second insulating heat-conducting layer 420 can be provided on a plate surface or hollowed out. The metal clip 500 can be a (such as Figure 5a and Figure 5b As shown), it can also be multiple (such as Figure 4a and Figure 4b shown).

[0047] It should be explained that providing the first insulating thermally conductive layer 410, or providing both the first and second insulating thermally conductive layers 420, appropriately increases the stiffness of the heating section, raising its natural frequency or increasing its damping, thereby reducing vibration and effectively reducing noise. Furthermore, this enhances the safety of the heating tape. If the heating tape burns out due to localized high temperature, the insulating thermally conductive layer will prevent the heating tape from escaping from the tape-passing groove 310, thus preventing any danger.

[0048] Optionally, see Figure 4a and Figure 4b The width of the first insulating and thermally conductive layer 410 is set to be greater than the width of the heat-producing belt 300, with the edges of the first insulating and thermally conductive layer 410 extending beyond the edges of the heat-producing belt 300. This is equivalent to placing the heat-producing belt in the middle of the first insulating and thermally conductive layer 410, preventing the heat-producing belt 300 from contacting the outer metal clip 500. More preferably, the widths of both the first insulating and thermally conductive layer 410 and the second insulating and thermally conductive layer 420 are set to be greater than the width of the heat-producing belt 300, with the edges of the first insulating and thermally conductive layer 410 extending beyond the edges of the heat-producing belt 300.

[0049] Optionally, see Figure 4a and Figure 4bThe width of the metal clip 500 is set to be greater than the width of the first insulating and heat-conducting layer 410, and a gap is provided between the width edge of the first insulating and heat-conducting layer 410 and the metal clip 500, thereby preventing the edge of the heat-producing belt 300 from contacting the metal clip 500. More preferably, the width of the metal clip 500 is set to be greater than the width of the second insulating and heat-conducting layer 420, and a gap is provided between the width edge of the second insulating and heat-conducting layer 420 and the metal clip 500, thereby further preventing the edge of the heat-producing belt 300 from contacting the metal clip 500.

[0050] If the insulating and thermally conductive layer is too thin, it will not be rigid enough; if it is too thick, it will exert excessive traction on the heat-generating belt 300, easily damaging it. Optionally, the thickness of the first insulating and thermally conductive layer 410 is set to 0.025mm-0.2mm, preferably 0.05mm-0.15mm, and more preferably 0.08mm-0.12mm; and / or the thickness of the second insulating and thermally conductive layer 420 is set to 0.025mm-0.2mm, preferably 0.05mm-0.15mm, and more preferably 0.08mm-0.12mm.

[0051] See also Figure 3 The width of the first insulating and thermally conductive layer 410 is greater than the width of the tape-passing slot 310, and / or the width of the second insulating and thermally conductive layer 420 is greater than the width of the tape-passing slot 310. It is understood that when the heat-generating belt 300 burns out due to high temperatures, it may elastically contract due to its flexibility and potentially break away from the support member 200 or even the frame 100, creating a dangerous situation. Therefore, the width of the insulating layer is set to be greater than the slot width so that when the heat-generating belt 300 contracts, the insulating layer is stuck in the tape-passing slot 310, preventing the heat-generating belt 300 from falling out.

[0052] Optionally, to further prevent the heat-generating belt 300 from shifting and contacting the metal clip 500, the surface of the first insulating and thermally conductive layer 410 that contacts the heat-generating belt 300 is preferably provided with a receiving groove, with the heat-generating belt 300 positioned within the receiving groove; or the surface of the second insulating and thermally conductive layer 420 that contacts the heat-generating belt 300 is preferably provided with a receiving groove, with the heat-generating belt 300 positioned within the receiving groove. The grooves prevent the heat-generating belt 300 from moving beyond the edges of the first and second insulating and thermally conductive layers 410, 420 and contacting the metal clip 500.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
