Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a heating element structure and a heater. Background Technology

[0002] Oil-filled radiators are a common heating device in homes and small offices. They work by heating an internal oil layer, which then transfers heat to the surrounding air through heat conduction and convection. However, existing oil-filled radiators often experience excessive temperature rise during actual use, affecting user comfort and potentially posing safety hazards such as burns or fires. Utility Model Content

[0003] Therefore, it is necessary to provide a radiator structure and heater to address the problem that existing electric oil heaters may overheat during actual use, affecting user comfort and even posing safety hazards.

[0004] The technical solution is as follows:

[0005] On the one hand, a body structure is provided, comprising:

[0006] The first slab has a perforation on at least one side;

[0007] The second plate is installed on the first plate and together with the first plate forms a closed cavity. The second plate is offset from the perforated hole to expose the perforated hole.

[0008] The technical solution will be further explained below:

[0009] In one embodiment, the first slab includes a first long side and a second long side disposed opposite to each other, both the first long side and the second long side are provided with the hollow hole, and the second slab is located between the first long side and the second long side.

[0010] In one embodiment, both the first long side and the second long side are provided with a hollow hole, and the two hollow holes are symmetrically arranged on opposite sides of the first slab.

[0011] In one embodiment, the first slab is further provided with a first oil pack and a second oil pack spaced apart along its own length direction. Along the length direction of the first slab, one side of the two hollow holes is located on opposite sides of the first oil pack, and the other side of the two hollow holes is located on opposite sides of the second oil pack.

[0012] In one embodiment, the cross-section of both of the perforations is elongated and is arranged along the length of the first slab, and the spacing between the two perforations is adapted to the width of the second slab.

[0013] In one embodiment, the second slab is provided with grooves on both sides near the two hollow holes, and the grooves penetrate the second slab along the axial direction of the hollow holes.

[0014] In one embodiment, the width of the perforation along the width direction of the first slab is set to 7mm to 10mm; the length of the perforation along the length direction of the first slab is set to 470mm to 500mm.

[0015] In one embodiment, the width of the perforation along the width direction of the first slab is set to 10 mm; the length of the perforation along the length direction of the first slab is set to 475 mm.

[0016] In one embodiment, the first strip includes a first short side and a second short side disposed opposite to each other, and the second strip is located between the first short side and the second short side.

[0017] On the other hand, a heater is provided, including the aforementioned stoker structure.

[0018] In the above embodiments, the perforated structure and heater have perforations located between the cavity and the sidewalls of the radiator structure. This reduces heat transfer from the central area of ​​the radiator structure to the sidewalls, lowering the sidewall temperature while increasing the central temperature, thus improving the heating efficiency and safety of the radiator structure. Compared with existing oil-filled radiators, the radiator structure and heater of this application have at least the following advantages: 1. Under the same heating power conditions, the sidewall temperature of the radiator structure decreases, while the central temperature increases. In other words, under the same sidewall temperature conditions, the first and second radiator plates can transfer heat at a higher power, resulting in a higher central temperature and faster heat transfer. There is no need to worry about detection and safety issues caused by excessive sidewall temperature rise, improving the practicality of the radiator structure. 2. The perforations on the first radiator plate increase air convection, thereby lowering the sidewall temperature, improving the heating efficiency of the radiator structure, shortening the heating time of the space, and achieving rapid drying and dehumidification. 3. The perforated design reduces the weight of the first slab, thereby reducing the overall weight of the slab structure, achieving a lightweight design, reducing packaging and transportation costs, and improving economic efficiency. 4. Structural improvements to the slab structure, specifically the perforated design of the first slab, result in better and more stable heating, a longer service life, and reduced malfunctions.

[0028] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] Oil-filled radiators are a common type of heating device used in homes and small offices. They heat an internal oil layer, which then transfers heat to the surrounding air through heat conduction and convection. Due to their high safety and stability, and quiet operation, oil-filled radiators hold a significant share of the heating equipment market.

[0030] The power rating of an oil-filled radiator is a crucial parameter affecting its heating efficiency and energy consumption. Choosing the appropriate power rating requires comprehensive consideration of room size, insulation, and usage habits. Multi-level power adjustment and intelligent temperature control systems can improve the efficiency and comfort of an oil-filled radiator. Improvements to the radiator's structure can also enhance heating performance, and a well-designed structure can result in better economic benefits.

[0031] Lightweight design is gaining increasing importance in modern home appliances, especially for heating devices like oil-filled radiators. Lightweight design not only improves portability and user experience but also offers significant advantages in several aspects. It makes oil-filled radiators easier to move, meeting users' portability needs and adapting to different usage scenarios. Lightweight design is often accompanied by a more modern appearance, satisfying users' aesthetic requirements for home products. It reduces safety risks during handling, preventing accidental injuries caused by excessive weight. Today, through structural design optimizations, such as using hollow structures and reducing material usage, the weight of oil-filled radiators can be reduced without sacrificing performance.

[0032] Despite the high safety and stability of oil-filled radiators, excessive wall temperature rise remains a common problem during actual use. Excessive wall temperature rise not only affects user comfort but can also pose safety hazards, such as burns or even fires. Currently, wall temperature rise testing is a key component of oil-filled radiator development, representing a crucial balance between performance and safety.

[0033] To address the issue of excessive temperature rise in oil-filled electric radiators, which negatively impacts user comfort, the inventors conducted in-depth analysis and research. They discovered that in oil-filled radiators, the surface of the fins is intact, and the side walls and center of the fins are a single unit. The temperature of the side walls is highly susceptible to influence from the center of the fins, potentially leading to excessive temperature rise during heating, causing burns and other safety hazards. Furthermore, the fins are made of low-carbon steel, and household appliances using oil-filled radiators are generally quite heavy, affecting the user experience.

[0034] The surface temperature of existing oil-filled radiators can reach up to 150 degrees Celsius, significantly affecting the side wall temperature. Specifically, the maximum side wall temperature can reach 106 degrees Celsius, approaching the national standard limit and posing a potential safety hazard. According to the national standards GB4706.1 and GB4706.23 for electric heaters, the surface temperature of oil-filled radiators must not exceed the 85K limit. Therefore, during the development of oil-filled radiators, with a test temperature of 25 degrees Celsius, the maximum surface temperature is set at 110 degrees Celsius.

[0035] Based on the above problems, the inventors designed and proposed the following embodiments of the stolon structure 10 and heater to solve the above technical problems.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a stepping stone structure 10 is provided, including a first stepping stone 100 and a second stepping stone 200. The first stepping stone 100 has a perforation 101 on at least one side. The second stepping stone 200 is mounted on the first stepping stone 100 and forms a closed cavity with the first stepping stone 100. The second stepping stone 200 is offset from the perforation 101 to expose the perforation 101.

[0037] In the above embodiment, the radiator structure 10 has a perforated hole 101 located between the cavity and the sidewall of the radiator structure 10. This reduces the heat transfer from the central region of the radiator structure 10 to the sidewall, lowering the sidewall temperature and raising the central region temperature, thus improving the heating efficiency and safety of the radiator structure 10. Compared with existing oil-filled electric radiators, the radiator structure 10 in this application has at least the following advantages: 1. Under the same heating power conditions, the sidewall temperature of the radiator structure 10 is lower, while the central region temperature is higher. In other words, under the same sidewall temperature conditions, the first radiator plate 100 and the second radiator plate 200 can perform heat transfer at a higher power, resulting in a higher central region temperature and faster heat transfer. This eliminates concerns about detection and safety issues caused by excessive sidewall temperature rise, improving the practicality of the radiator structure 10. 2. The perforated holes 101 on the first slab 100 increase air convection, thereby reducing the temperature at the side walls, improving the heating efficiency of the slab structure 10, shortening the heating time of the space, and achieving rapid drying and dehumidification. 3. The perforated holes 101 reduce the weight of the first slab 100, thus reducing the overall weight of the slab structure 10, achieving a lightweight design, reducing packaging and transportation costs, and improving its economic efficiency. 4. By improving the structure of the slab structure 10, specifically by designing the first slab 100 with perforations, the heating effect becomes better and more stable, the service life is longer, and it is less prone to malfunction.

[0038] The misalignment of the second plate 200 and the hollow hole 101 means that the projection area of ​​the second plate 200 does not coincide with the projection area of ​​the hollow hole 101 along the axial direction of the hollow hole 101.

[0039] The shape, number, and position of the perforations 101 can be flexibly adjusted according to actual usage needs, as long as they can reduce the heat transfer from the central region of the slab structure 10 to the sidewalls of the slab structure 10. Specifically, the first slab 100 may have perforations 101 on one, two, three, or four sides. The number of perforations 101 on any side of the first slab 100 may be greater than or equal to zero.

[0040] Specifically, in this embodiment, the length and width of the first slab 100 are both greater than the length and width of the second slab 200. The second slab 200 can be installed in the central area of ​​the first slab 100 by welding or other fixed connection methods, and is spaced apart from the outer wall of the first slab 100 (i.e., the side wall of the slab structure 10).

[0041] like Figure 3 and Figure 4 As shown, the first stepping piece 100 further includes a first long side 102 and a second long side 103 disposed opposite to each other. Both the first long side 102 and the second long side 103 are provided with a perforated hole 101. The second stepping piece 200 is located between the first long side 102 and the second long side 103. Thus, the perforated hole 101 is located on the long side of the first stepping piece 100, and the perforated hole 101 is along the length direction of the first stepping piece 100 (e.g., ...). Figure 1 The size of the direction shown in A can be increased, and the hollow area on the first slab 100 is correspondingly increased. The hollow hole 101 can block more heat, and the cooling effect of the side wall of the slab structure 10 and the heating effect of the central area of ​​the slab structure 10 are more obvious, thus improving the practicality of the slab structure 10.

[0042] Specifically, in this embodiment, the perforated holes 101 can all be configured as waist-shaped holes. The first slab 100 also has a first oil reservoir 104 and a second oil reservoir 105 spaced apart along its length. Along the length of the first slab 100, one side of each of the two perforated holes 101 is located on opposite sides of the first oil reservoir 104, and the other side of each of the two perforated holes 101 is located on opposite sides of the second oil reservoir 105. In this way, the length of the perforated holes 101 along the length of the first slab 100 can be maximized.

[0043] like Figure 1 and Figure 4As shown, optionally, both the first long side 102 and the second long side 103 are provided with a hollow hole 101. The two hollow holes 101 are symmetrically arranged on opposite sides of the first slab 100. In this way, the symmetrical design of the hollow holes 101 can maximize the hollow area while improving the aesthetic appearance of the slab structure 10.

[0044] In other embodiments, the two perforated holes 101 may also be asymmetrically arranged on opposite sides of the first plate 100.

[0045] like Figure 1 and Figure 3 As shown, in one embodiment, the cross-sections of both perforated holes 101 are elongated and are both arranged along the length direction of the first slab 100. The spacing between the two perforated holes 101 is adapted to the width of the second slab 200. Thus, the perforated holes 101 can be fitted to the outer wall of the second slab 200, and the perforated holes 101 are arranged along the width direction of the first slab 100 (e.g., ...). Figure 1 The size of the direction shown in B can be increased, and the hollow area on the first slab 100 is correspondingly increased. The hollow hole 101 can block more heat, and the cooling effect of the side wall of the slab structure 10 and the heating effect of the central area of ​​the slab structure 10 are more obvious, thus improving the practicality of the slab structure 10.

[0046] like Figure 1 and Figure 5 As shown, optionally, the second stepping piece 200 has grooves 201 on both sides near the two hollow holes 101. The grooves 201 penetrate the second stepping piece 200 along the axial direction of the hollow holes 101. In this way, during assembly, the grooves 201 can be used as welding positions, thereby increasing the welding length between the first stepping piece 100 and the second stepping piece 200 and improving the reliability of the stepping body structure 10.

[0047] Specifically in this embodiment, along the length of the first plate 100, both inner walls of the groove 201 are inclined, and the length of the groove opening of the groove 201 is greater than the length of the bottom wall of the groove 201.

[0048] In one embodiment, the width of the perforated hole 101 along the width direction of the first slab 100 is set to 7 mm to 10 mm. The length of the perforated hole 101 along the length direction of the first slab 100 is set to 470 mm to 500 mm.

[0049] The solution in this embodiment was tested, and the results showed that, compared with existing oil-filled radiators, under the same heating power conditions, the sidewall temperature of the radiator structure 10 can be reduced by about 10 degrees Celsius, while the temperature of the central area of ​​the radiator structure 10 can be increased by about 5 degrees Celsius. Furthermore, compared with existing radiator plates, the weight of the first radiator plate 100 in this application can be reduced by about 10%.

[0050] The width of the perforated hole 101 along the width direction of the first step plate 100 can be set to 8mm, 9mm or 10mm, etc. The length of the perforated hole 101 along the length direction of the first step plate 100 can be set to 480mm, 485mm, 490mm or 495mm, etc.

[0051] Specifically, in this embodiment, the width of the perforated hole 101 along the width direction of the first slab 100 is set to 10mm; the length of the perforated hole 101 along the length direction of the first slab 100 is set to 475mm.

[0052] like Figure 1 and Figure 4 As shown, in one embodiment, the first stepper 100 includes a first short side 106 and a second short side 107 disposed opposite to each other, and the second stepper 200 is located between the first short side 106 and the second short side 107.

[0053] Specifically, in this embodiment, the first long side 102, the first short side 106, the second long side 103, and the second short side 107 are sequentially connected to enclose and form a central region. The second slab 200 is installed in the central region. In this way, the size of the second slab 200 can be further reduced, realizing a lightweight design of the slab structure 10.

[0054] Specifically, in this embodiment, the second slab 200 has a third oil reservoir 202 and a fourth oil reservoir 203 at both ends along its length. The third oil reservoir 202 is configured to correspond to the first oil reservoir 104 when the second slab 200 is mounted on the first slab 100. The fourth oil reservoir 203 is configured to correspond to the second oil reservoir 105 when the second slab 200 is mounted on the first slab 100. Both inner sidewalls of the second slab 200 along its length are formed into arc surfaces. One of the two arc surfaces is coaxial with the third oil reservoir 202, and the other is coaxial with the fourth oil reservoir 203.

[0055] In one embodiment, a heater is provided, including the sill structure 10 of any of the above embodiments. Thus, the heater possesses all the advantages of the sill structure 10 described above.

[0056] Specifically, when the heater is in use, the perforated hole 101 is located between the cavity and the side wall of the radiator structure 10, so as to reduce the heat transfer from the central area of ​​the radiator structure 10 to the side wall, thereby lowering the temperature of the side wall and raising the temperature of the central area, thus improving the heating efficiency and safety of the heater.

[0057] Among them, heaters can be used in dryers, heaters or other equipment that requires heating.

[0058] The number of the treadmill structure 10 can be flexibly adjusted according to actual usage needs.

[0059] Specifically, in this embodiment, the number of tidal bodies 10 is at least one, and each tidal body structure 10 is arranged in a linear array and connected in sequence.
