Description
Technical Field
[0001] This utility model relates to the field of heating equipment technology, and in particular to a far-infrared heater that can heat the human body. Background Technology
[0002] Far-infrared heaters are devices that generate heat to ward off the cold when powered on. Their structure typically includes a casing and a heating element built into it. Traditional far-infrared heaters usually use a fan to deliver hot air; however, the noise and draft from the fan can often cause discomfort. Therefore, modern far-infrared heaters tend to use larger heating elements, utilizing natural air convection and the heat radiation from the heating element to achieve a more comfortable heating effect. Although far-infrared heaters can raise the temperature of an entire room, for people living in extremely cold regions or those who are prone to feeling cold, only the radiant heat from the front of the heating panel is sufficient to meet their temperature needs. Furthermore, most common far-infrared heaters on the market are baseboard type, which are low and only cover the user's knees, thus providing warmth only to the lower body and failing to achieve a truly comfortable temperature level.
[0003] In addition, to heat up quickly, far-infrared heaters are typically equipped with high power, resulting in high temperatures for the heating elements inside the device. Accidental contact could cause burns. Therefore, far-infrared heaters need to have a protective mesh on the outer casing; larger openings in the mesh result in better heating, but safety regulations limit the size of these openings. How to minimize heat radiation obstruction while complying with safety regulations is a problem that far-infrared heaters need to solve. Utility Model Content

[0045] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.
[0046] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.
[0047] The following detailed explanation uses specific examples:
[0048] like Figures 1 to 8 As shown, the first embodiment of this utility model provides a far-infrared heater that can heat the human body, including a shell 110, a first protective net 120 and a heating element 200 disposed inside the shell 110;
[0049] like Figure 3 As shown, the housing 110 is a vertically elongated strip, and the first protective net 120 is fixedly installed on the housing 110. The first protective net 120 has multiple mesh holes 160, which are rectangular strip holes.
[0050] Multiple meshes 160 are arranged vertically to form a column, and multiple groups of vertical columns are arranged horizontally in parallel to form a matrix. The meshes 160 in the odd-numbered columns are horizontally aligned, and the meshes 160 in the even-numbered columns are horizontally aligned. The starting positions of the meshes 160 in the odd-numbered columns are staggered vertically from the starting positions of the meshes 160 in the even-numbered columns.
[0051] In this embodiment, the starting position of the even-numbered vertical columns of mesh 160 is horizontally aligned with the center point of the odd-numbered vertical columns of mesh 160, and the starting position of the odd-numbered vertical columns of mesh 160 is offset vertically from the starting position of the even-numbered vertical columns of mesh 160 by a distance equal to half the length of the mesh 160.
[0052] Specifically, the vertical and horizontal spacing of the mesh 160 is the same, and the starting position of the even-numbered vertical column mesh 160 is the middle position of the odd-numbered vertical column mesh 160.
[0053] In this embodiment, the width of the mesh 160 is 5mm-12mm, preferably 8mm; the length of the mesh 160 is 53mm-93mm, preferably 73mm; and the spacing between the meshes 160 is 1.5mm-2.5mm, preferably 1.8mm. The aspect ratio of the rectangular holes is between 5:93 and 12:53, preferably 8:73. Testing showed that when the width of the rectangular holes is 8mm, the length is 73mm, and the spacing between the rectangular holes is 1.8mm, the optimal dimensions meet safety requirements, resulting in the best heat transfer performance. The mesh 160 is aligned with the heating element 200 within the housing 110, and the area of the mesh area is slightly larger than the area of the heating element 200. From a frontal view, the mesh area covers the heating element 200, which helps improve heat transfer efficiency.
[0054] In this embodiment, the far-infrared heater also includes a second protective net 130. The housing 110 is a sleeve-shaped annular frame, similar to a rectangular frame with rounded corners. The housing 110 is made by bending a rectangular straight plate, or it can be made by splicing multiple straight plates and multiple curved plates. The first protective net 120 and the second protective net 130 are respectively fixedly installed on the two end faces of the housing 110 and enclose the interior of the housing 110. The heating element 200 divides the interior of the housing 110 into two parts, wherein the space between the heating element 200 and the first protective net 120 is a convection cavity 140.
[0055] Specifically, when the heating element 200 is a single-sided heating element, the generated heat first passes through the convection cavity 140 and then dissipates through the mesh 160 of the first protective mesh 120. When the heating element 200 is a double-sided heating element, the generated heat is dissipated simultaneously through the mesh 160 of both the first protective mesh 120 and the second protective mesh 130.
[0056] Specifically, the boundary of the first protective net 120 is provided with a bent edge that is fixedly connected to the inner wall surface of the housing 110. The housing 110 also includes an L-shaped connecting bracket, which is fixedly connected to both the second protective net 130 and the inner wall surface of the housing 110. A first fastener 330 passes through the connecting bracket and the second protective net 130 and fixes them together. Optionally, the connecting bracket can also be integrated with the second protective net 130, similar to the bent edge structure at the boundary of the first protective net 120.
[0057] In this embodiment, the bottom of the housing 110 is provided with a heat dissipation hole 150 communicating with the convection cavity 140. Optionally, the side and / or top of the housing 110 are also provided with heat dissipation holes 150 communicating with the convection cavity 140 to realize air convection.
[0058] like Figure 2 , 4 As shown in Figures 7 and 8, in this embodiment, the second protective net 130 has a mesh area and a non-mesh area. The mesh area has mesh holes 160 (rectangular holes) and / or round holes, and the non-mesh area is located below the mesh area. The non-mesh area is used to cover the circuit wires and other components inside the housing 110 to prevent the user from seeing them.
[0059] like Figure 4 , 5As shown in Figure 7, in this embodiment, the far-infrared heater further includes a connecting component 300 disposed inside the housing 110. The connecting component 300 includes a U-shaped frame 310, an elastic element 320, a first fastener 330, and a second fastener 340. The U-shaped frame 310 includes a long side surface 311 and a short side surface 312 arranged in parallel, as well as a connecting side surface 313. The first fastener 330 is fixedly connected to the housing 110, the second fastener 340 is fixedly connected to the short side surface 312, and the two ends of the elastic element 320 are fixedly connected to the first fastener 330 and the second fastener 340, respectively.
[0060] The heating element 200 is fixedly connected to the long side surface 311. The elastic element 320 is used to generate elastic deformation after being subjected to force, so that the U-shaped frame 310 and the heating element 200 can perform elastic reciprocating motion together. The heating element 200 is fixedly connected to the side of the long side surface 311 facing the short side surface 312. The second fastener 340 is disposed in the space enclosed by the side of the U-shaped frame 310 and the heating element 200.
[0061] The function of the elastic element 320 is to reduce the impact force on the heating element 200 by elastic deformation when the far-infrared heater is tilted, shaken, or vibrated, thus protecting the heating element 200 from breakage. The function of the U-shaped frame 310 and the second fastener 340 is to connect the elastic element 320 and the heating element 200. Due to the small space inside the housing 110, the U-shaped frame 310 simplifies the installation process and has a simple structure and low cost. There is a gap between the connecting side 313 of the U-shaped frame 310 and the housing 110, so that when the U-shaped frame 310 and the heating element 200 move elastically together, they will not touch the housing 110.
[0062] In this embodiment, the second fastener 340 includes a screw 341 and a nut 342. One end of the screw 341 is disposed within the space enclosed by the U-shaped frame 310 and the heating component 200, and the other end of the screw 341 passes through the short side surface 312 and is fixedly connected to the nut 342. The nut 342 is provided with a protrusion 343 that is fixedly connected to the elastic member 320. The advantage of this design is that it is convenient to assemble, has low cost, and provides a stable connection.
[0063] In this embodiment, the far-infrared heater further includes a first shielding plate 400 and a second shielding plate 500; the first shielding plate 400 is fixedly connected to the long side surface 311 and is disposed at the bottom of the heating element 200 to cover the area between the bottom of the heating element 200 and the bottom of the housing 110; the second shielding plate 500 is disposed between the housing 110 and the heating element 200 and is fixedly connected to the housing 110; the second shielding plate 500, the housing 110, the first shielding plate 400, and the heating element 200 form an accommodating space.
[0064] Specifically, the first protective net 120 and the second protective net 130 are rounded rectangles, while the heating element 200 is rectangular. The first baffle plate 400 is used to cover the gap between the bottom of the heating element 200 and the bottom of the housing 110. The first baffle plate 400 is fixedly connected to the long side surface 311, and the first baffle plate 400 and the heating element 200 are respectively fixedly connected to two opposite sides of the long side surface 311. There is a gap between the first baffle plate 400 and the housing 110, and the first baffle plate 400 moves elastically back and forth together with the U-shaped frame 310 and the heating element 200.
[0065] Specifically, the side of the second baffle 500 is fixedly connected to the inner wall of the housing 110. There is a gap between the second baffle 500 and the heating element 200, which will not hinder the movement of the heating element 200. The second baffle 500, the housing 110, the first baffle 400, and the heating element 200 form a receiving space for storing electronic components such as circuit board wires, preventing users from seeing them, and making the far-infrared heater more aesthetically pleasing and simple.
[0066] like Figure 7 As shown, in this embodiment, another first shielding plate 400 is also provided above the heating component 200. The two first shielding plates 400 have the same shape. The upper first shielding plate 400 is used to shield the area between the top of the heating component 200 and the bottom of the housing 110.
[0067] like Figure 4 As shown, in this embodiment, the heating component 200 includes a first panel 210, a second panel 220, a heating layer 230 sandwiched between the first panel 210 and the second panel 220, and a conductor 240 that passes through the second panel 220 and is connected to the heating layer 230. The first panel 210 is fixedly connected to the long side surface 311.
[0068] Specifically, both the first panel 210 and the second panel 220 are glass plates. The heating component 200 works by far-infrared heating. The heating layer 230 is single-sided or double-sided heating. Heat is dissipated outward through the first panel 210 and the second panel 220.
[0069] Specifically, conventional far-infrared heaters in the prior art incorporate heat insulation cotton on the heating element 200, while this embodiment eliminates the heat insulation cotton, allowing the heating element 200 to generate heat at a higher power. Furthermore, the absence of heat insulation cotton promotes heat dissipation. With good heat dissipation in the housing 110, the power consumption is lower than that of conventional far-infrared heaters to achieve the same warming effect.
[0070] In this embodiment, the extension and retraction direction of the elastic member 320 is set to be perpendicular to the first panel 210, and the heating component 200 performs elastic reciprocating motion in a direction perpendicular to the first panel 210.
[0071] Specifically, the elastic element 320 is an elastic element 320 that can undergo elastic deformation, such as a spring.
[0072] Specifically, when the far-infrared heater is tilted, it usually tilts or even falls over along the vertical direction of the first protective net 120 or the second protective net 130. Therefore, the extension and retraction direction of the elastic element 320 is set to be perpendicular to the first panel 210. After tilting, the heating element 200 makes up-down elastic reciprocating motion, which can minimize the impact force on the heating element 200.
[0073] When the far-infrared heater shakes, vibrates, or tilts in other directions, the direction of force on the heating element 200 is not limited to the vertical direction along the first protective net 120 or the second protective net 130, but may be any direction in space. After the heating element 200 is subjected to force, the elastic element 320 will swing, which can minimize the impact force on the heating element 200.
[0074] In this embodiment, the extension and retraction direction of the elastic member 320 can also be set to be parallel to the first panel 210. The two ends of the elastic member 320 are fixedly connected to the housing 110 and the connecting side surface 313, and the heating component 200 performs elastic reciprocating motion in a direction parallel to the first panel 210.
[0075] In this embodiment, as Figure 1 and Figure 2 As shown, the housing 110 also includes a base bracket, which is fixedly connected to the bottom of the housing 110 to support it. The base bracket also serves as a counterweight; its weight is designed so that the housing 110 will not tip over when tilted at 15°, and can return to its normal position, meeting safety regulations. Furthermore, the base bracket is equipped with perforations for the ventilation holes 150 to ensure normal operation.
[0076] In this embodiment, the far-infrared heater also includes a shelf 600, which is fixedly mounted on the top of the housing 110. The projected area of the shelf 600 is larger than that of the housing 110. Specifically, the far-infrared heater is a type of heating table. Objects can be placed on the shelf 600. Because the projected area of the shelf 600 is larger than that of the housing 110, users can place their legs under the shelf 600 when sitting next to the heating table for convenient warmth.
[0077] Specifically, in this embodiment, a heat dissipation hole 150 communicating with the convection cavity 140 is only provided at the bottom of the housing 110. Because a storage tray 600 is provided at the top of the housing 110, when a cloth item is covered on the storage tray 600, it will spread out along the edge of the storage tray 600, and the cloth item will not block the front and rear first protective nets 120 and second protective nets 130. Even if a cloth item covers the storage tray 600, the heat of the heating component 200 can still be dissipated normally, so no heat dissipation hole 150 is provided on the side and / or top of the housing 110.
[0078] Specifically, the storage tray 600 can be used to heat some small food items. The heat from the heating element 200 is dissipated upwards and transferred to the storage tray 600 through the top of the housing 110.
[0079] like Figures 9 to 10 As shown, the second embodiment of this utility model provides a far-infrared heater that can heat the human body. The overall structure is the same as that of the first embodiment. The difference is that the far-infrared heater in the second embodiment does not have a shelf 600 on the top. The side and top surfaces of the shell 110 are provided with heat dissipation holes 150 that are connected to the convection cavity 140. The mesh holes 160 on the second protective net 130 are round holes.
[0080] In this embodiment, the bottom of the housing 110 is provided with a heat dissipation hole 150 communicating with the convection cavity 140, and the side and / or top of the housing 110 are also provided with heat dissipation holes 150 communicating with the convection cavity 140. Specifically, the side and top of the housing 110 are provided with heat dissipation holes 150 communicating with the convection cavity 140, and the shape of the heat dissipation hole 150 is an elongated hole.
[0081] Specifically, in this embodiment, heat dissipation holes 150 communicating with the convection cavity 140 are provided on the bottom, sides, and top of the housing 110. Because the top of the housing 110 does not have a shelf 600, when a cloth item is covered on the top of the housing 110, the cloth item will block the front and rear first protective nets 120 and second protective nets 130, and the heat of the heating component 200 cannot be dissipated normally. Therefore, heat dissipation holes 150 need to be provided on the sides and / or top of the housing 110.
[0082] In this embodiment, the second protective net 130 is provided with a mesh area and a non-mesh area. The mesh area is provided with rectangular or round holes, and the non-mesh area is located below the mesh area.
[0083] Specifically, multiple mesh holes 160 are provided within the mesh area, and the mesh holes 160 are round holes.
[0084] In this embodiment, the second protective net 130 is divided into upper and lower components. The lower component is a plate, with the non-mesh area located on the plate. The upper component is a mesh, with the mesh area located on the mesh. Compared to the integrated second protective net 130, the split-type second protective net 130 has the advantages of lower cost and simpler installation.
[0085] In this embodiment, a shelf 600 is not provided on the top of the housing 110. The far-infrared heater in this embodiment is shaped as a vertical strip and is taller than the far-infrared heater in the first embodiment, so that it can warm from the feet to the neck.
[0086] In this embodiment, the first panel 210 is a glass plate, and the second panel 220 is a mica plate. The second panel 220 has a certain effect of blocking and preventing heat transfer, allowing most of the heat to dissipate from the direction of the first panel 210. In actual use, the second panel 220 is placed facing a wall or similar surface, while the first panel 210 is placed facing the user, operating similarly to a floor-standing air conditioner.
[0087] Specifically, when the second panel 220 is a mica board, the connecting component 300 can be omitted, and the heating component 200 can be directly fixedly connected to the housing 110.
[0088] In summary, this utility model embodiment achieves maximum heating effect while complying with safety regulations by setting a protective net on the shell, with regularly distributed mesh holes on the protective net, wherein the starting positions of the odd-numbered vertical columns of mesh holes are staggered from the starting positions of the even-numbered vertical columns of mesh holes.
[0089] Furthermore, the mesh openings are rectangular; the width of the mesh openings is 5mm-12mm, with a preferred value of 8mm; the length of the mesh openings is 53mm-93mm, with a preferred value of 73mm; and the spacing between the mesh openings is 1.5mm-2.5mm, with a preferred value of 1.8mm. The optimized shape of the mesh openings facilitates heat flow and results in better heating performance.
[0090] Furthermore, the second shield, the housing, the first shield, and the heating element form a recessed space. This space can accommodate circuit components, keeping them out of the user's sight, making it simple and practical. It also prevents the circuit components from being exposed and damaged.
[0091] Furthermore, the heating element is connected to the housing via a connecting component, and when the far-infrared heater is tilted, the elastic element of the connecting component can undergo elastic deformation to reduce the impact force on the heating element and prevent damage to the heating element.
[0092] Furthermore, a shelf can be fixed to the top of the casing to function as a table.
[0093] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
