Description

Technical Field

[0001] This utility model relates to the field of household and electrical appliance technology, and in particular to a grilling appliance. Background Technology

[0002] The heating element of a grilling appliance typically includes a heat-conducting plate and a heating element fixed to the plate. During use, the heating element generates heat, which is then transferred to the heat-conducting plate, heating the grill pan. This process results in a long preheating time. Furthermore, the surface of the heat-conducting plate and the bottom of the grill pan are in surface contact, requiring a high degree of flatness between these surfaces, thus necessitating more sophisticated manufacturing processes. Utility Model Content

[0003] Therefore, it is necessary to provide a frying and grilling appliance that can ensure heating effect while having a simple processing technology to address the above problems.

[0004] This utility model provides a grilling appliance, comprising: a shell assembly having an assembly cavity, the shell assembly having a thermostat; a grilling pan disposed within the assembly cavity; and a heating element, which is spiral-shaped and has a central region, the heating element being disposed within the assembly cavity, wherein when the grilling pan is placed in the assembly cavity, the top wall of the heating element contacts the bottom wall of the grilling pan; wherein, the temperature sensing end of the thermostat is located within the central region, and the distance from the temperature sensing end of the thermostat to the inner wall of the heating element surrounding the central region is L, satisfying: 10mm≤L≤45mm.

[0005] In the aforementioned grilling appliance, the heating element is in direct contact with the grill pan, allowing the heat generated by the heating element to be directly and quickly transferred to the grill pan. This shortens the preset heating time, improves heating efficiency, reduces the number of parts and material costs, and the top wall of the heating element forms a line contact with the bottom wall of the grill pan, enabling the heating element to better fit the grill pan. This reduces the requirements for the flatness of the bottom wall of the grill pan, simplifies the manufacturing process, and improves production efficiency and product reliability. Furthermore, by placing the temperature-sensing end of the thermostat within the central area and defining the positional relationship between the thermostat and the central area, the temperature-sensing end of the thermostat can directly sense the heat. The heating element (L) is positioned to precisely reflect the heating temperature of the core heating area of ​​the baking pan. This prevents the temperature sensor (L) from being too small, causing it to be too close to the heating element and detect a temperature far exceeding the actual operating temperature of the baking pan, thus affecting the accuracy of the temperature measurement. Conversely, it prevents the heating element from being too large, resulting in a cold spot in the center area, which would prevent the temperature sensor from effectively sensing the heating temperature of the baking pan and affecting the uniformity and accuracy of heating. Therefore, the temperature sensor is positioned to accurately reflect the heating temperature, ensuring uniform and accurate heating of the baking pan and improving cooking results.

[0006] In one embodiment, the distance between the center point of the temperature sensing end of the thermostat and the inner wall of the heating tube that forms the central region is L1, which satisfies 35mm≤L1≤100mm.

[0007] This configuration prevents L1 from being too small, resulting in insufficient space in the central area to accommodate the thermostat, or causing the distance between the thermostat and the heating element to be too close, thus affecting the accuracy of temperature measurement. At the same time, it prevents L1 from being too large, resulting in cold zones in the central area and the baking tray, which would prevent the temperature sensing end of the thermostat from effectively sensing the heating temperature of the heating element on the baking tray.

[0008] In one embodiment, the heating element includes a heating section and an electrical terminal disposed at the end of the heating section, the heating section being spiral-shaped and spiraling at least two turns.

[0009] This design increases the contact area between the heating element and the baking pan, allowing the heating element to distribute heat more evenly across the entire bottom wall of the baking pan.

[0010] In one embodiment, the distance L2 between the heating tube walls of two adjacent heating sections satisfies: 10mm≤L2≤40mm.

[0011] This design avoids L2 being too small, making it difficult to position the heating section during the heating element manufacturing process and increasing the difficulty of the process, while also preventing localized overheating; it also avoids L2 being too large, which would cause the heating section to bend too much, making it prone to cracking during bending and bursting during heating, and also avoids the existence of cold spots, which would affect the uniformity of heating the baking pan by the heating section.

[0012] In one embodiment, the heating section is in the shape of a single helix, with one electrical terminal located at the center of the helical heating section and the other electrical terminal located on the outer periphery of the helical heating section.

[0013] This design avoids excessive space occupied by the power terminals, which could lead to localized low-temperature areas on the heating element, thus ensuring more even heating of the baking pan. It also prevents interference between the cables connected to the two power terminals, making wiring easier for the user.

[0014] In one embodiment, the heating section is in the shape of a double helix, and the electrical terminals are all located on the outer periphery of the helical heating section.

[0015] This design results in high structural strength and stability of the heating section, and also makes the heat field distribution more dense and uniform. At the same time, it allows users to easily connect wires on the outside of the heating element, making the assembly process simpler and safer.

[0016] In one embodiment, the heating element further includes a fixing piece connected to the electrical terminal, the fixing piece being fixed to the inner wall of the assembly cavity by fasteners.

[0017] This design prevents the power terminals from becoming loose or damaged, ensuring a reliable electrical connection between the power terminals and the power cord, thus improving safety. Furthermore, the mounting and disassembly of the fixing plate is simple, making it easy for users to disassemble or maintain the heating element.

[0018] In one embodiment, the housing assembly includes an outer shell and a reflector, the reflector being disposed within the outer shell and forming the assembly cavity with the outer shell, and the heating element being fixed to the reflector.

[0019] With this configuration, the reflector is used to reflect the heat radiated by the heating element towards the reflector back to the baking pan, reducing heat loss and helping to improve the temperature uniformity of the baking pan; it also protects the heating element, preventing it from directly contacting other structures inside the housing assembly, thus improving safety during use.

[0020] In one embodiment, the baking tray is detachably disposed in the assembly cavity.

[0021] This design allows users to easily disassemble and clean the baking tray, and also facilitates the disassembly and maintenance of the heating element inside the assembly cavity. Attached Figure Description

[0038] The heating element of a grilling appliance typically includes a heat-conducting plate and a heating element fixed to the plate. During use, the heating element generates heat, which is then transferred to the heat-conducting plate, heating the grill pan. This process results in a long preheating time. Furthermore, the surface of the heat-conducting plate and the bottom of the grill pan are in surface contact, requiring a high degree of flatness between these surfaces, thus necessitating more sophisticated manufacturing processes.

[0039] To solve the above problems, such as Figures 1 to 9 As shown, this utility model first provides a frying and grilling appliance to ensure heating effect, while the processing technology is simple.

[0040] like Figure 1 , Figure 4 and Figure 6 As shown, specifically, the grilling appliance includes a housing assembly 10, a grilling pan 20, and a heating element 30. The housing assembly 10 has an assembly cavity 11 and a thermostat 12 is mounted on the housing assembly 10. The grilling pan 20 is disposed within the assembly cavity 11. The heating element 30 is spiral-shaped and has a central region 311. The heating element 30 is disposed within the assembly cavity 11, and when the grilling pan 20 is placed in the assembly cavity 11, the top wall of the heating element 30 contacts the bottom wall of the grilling pan 20. The temperature sensing end of the thermostat 12 is located within the central region 311, and the distance from the temperature sensing end of the thermostat 12 to the inner wall of the heating element 30 surrounding the central region 311 is L, satisfying: 10mm ≤ L ≤ 45mm. L can be any value within the range of 10mm to 45mm, such as 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, or 45mm.

[0041] It should be noted that the central region 311 of the heating element 30 refers to the area enclosed by the innermost ring of the spiral heating element 30, that is... Figure 4 and Figure 6 In the middle, the area corresponding to the 360-degree spiral outward from the center of the self-heating tube 30.

[0042] In the grilling appliance provided by this utility model embodiment, the heating element 30 is in direct contact with the baking pan 20, eliminating the need for the traditional heat-conducting plate structure. This allows the heat generated by the heating element 30 to be directly and quickly transferred to the baking pan 20, shortening the preset time, improving heating efficiency, reducing the number of parts and material costs. Furthermore, the top wall of the heating element 30 forms a line contact with the bottom wall of the baking pan 20, enabling the heating element 30 to better fit the baking pan 20. This reduces the requirements for the flatness of the bottom wall of the baking pan 20, simplifies the processing technology, and improves production efficiency and product reliability. Meanwhile, the temperature sensing end of the thermostat 12 is located within the central region 311, and the positional relationship between the thermostat 12 and the central region 311 is defined, so that the temperature sensing end of the thermostat 12 can directly sense the heating temperature of the core heating area of ​​the baking pan 20 by the heating element 30; L≥10mm, to prevent L from being too small, causing the temperature sensing end of the thermostat 12 to be too close to the heating element 30, resulting in a temperature that is much higher than the actual working temperature of the baking pan 20, affecting the accuracy of the temperature measurement result; L≤45mm, to prevent L from being too large, causing the central region 311 to be too large and having a cold area, making it impossible for the temperature sensing end of the thermostat 12 to effectively sense the heating temperature of the baking pan 20 by the heating element 30, affecting the uniformity and accuracy of the heating of the baking pan 20 by the heating element 30; thus, the temperature sensing end of the thermostat 12 is in a position that can accurately reflect the heating temperature, ensuring the uniformity and accuracy of the heating of the baking pan 20 by the heating element 30, and improving the cooking effect.

[0043] like Figure 4 and Figure 6As shown, in one embodiment, the distance L1 between the center point of the temperature sensing end of the thermostat 12 and the inner wall of the heating element 30 forming the central region 311 satisfies 35mm ≤ L1 ≤ 100mm. L1 can be any value within the range of 35mm to 100mm, such as 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, or 100mm. Those skilled in the art should understand that when the lines containing L and L1 coincide, L1 > L must be satisfied; for example, when L1 = 35mm, L cannot be 45mm. Thus, L1 ≥ 35mm prevents L1 from being too small, resulting in insufficient space within the central area 311 to accommodate the thermostat 12, or causing the distance between the thermostat 12 and the heating element 30 to be too close, affecting the accuracy of temperature measurement; L1 ≤ 100mm prevents L1 from being too large, resulting in cold zones in the central area 311 and the baking tray 20, making it impossible for the temperature sensing end of the thermostat 12 to effectively sense the heating temperature of the baking tray 20 by the heating element 30; thereby further ensuring the uniformity and accuracy of heating of the baking tray 20 by the heating element 30. Of course, in other embodiments, L1 can also be set to less than 35mm or greater than 100mm depending on factors such as the size of the baking tray 20 and the thermostat 12, and the heating power of the heating element 30.

[0044] like Figure 3 and Figure 5 As shown, the heating element 30 includes a heating section 31 and a power terminal 32 disposed at the end of the heating section 31. The heating section 31 is spiral-shaped and has at least two turns. It should be noted that "at least two turns" means a spiral of at least 720 degrees outward from the center of the heating section 31. The power terminal 32 is used to connect a power cord. The spiral heating section 31 is in direct contact with the baking pan 20 and is used to heat the baking pan 20. The fact that the heating section 31 has at least two turns increases the contact area between the heating section 31 and the baking pan 20, allowing the heating section 31 to more evenly transfer heat to the entire bottom wall of the baking pan 20, further improving the heating effect and uniformity of the heating section 31 on the baking pan 20.

[0045] In the illustrated embodiment, the heating section 31 spirals three times. This ensures a sufficiently large contact area between the heating section 31 and the baking pan 20, resulting in a denser and more uniform heat distribution, while avoiding excessive spirals that would increase processing difficulty and cost. Of course, in other embodiments, the heating section 31 can be configured with one, one and a half, two, two and a half, three and a half, four, or more spirals, depending on factors such as the size of the baking pan 20 and the heating power of the heating element 30, as long as the heating effect and uniformity of the heating section 31 on the baking pan 20 are ensured. This embodiment of the invention does not impose specific limitations here.

[0046] like Figures 3 to 4 As shown, in one embodiment, the heating section 31 is in the shape of a single spiral, with one electrical terminal 32 located at the center of the spiral heating section 31 and the other electrical terminal 32 located on the outer periphery of the spiral heating section 31. Thus, since the electrical terminal 32 itself does not generate heat, distributing the two electrical terminals 32 avoids excessive space occupied by the electrical terminals 32, which could lead to localized low-temperature areas in the heating element 30, thereby ensuring more uniform heating of the baking pan 20 by the heating element 30. Simultaneously, it also prevents interference between the cables connected to the two electrical terminals 32, facilitating user wiring.

[0047] like Figures 5 to 6 As shown, in another embodiment, the heating section 31 is in the shape of a double helix, and the electrical terminals 32 are all located on the outer periphery of the helical heating section 31. It should be noted that the double helix shape means that each turn of the heating section 31 includes two synchronously spiral heating sections 31, and the innermost sides of the two heating sections 31 are connected to each other. The double helix heating section 31 has high structural strength and good stability, and also makes the heat field distribution more dense and uniform. At the same time, the fact that both electrical terminals 32 are located on the outer periphery of the helical heating section 31 also facilitates wiring by the user on the outside of the heating element 30, making the assembly process simpler and safer. Alternatively, the two electrical terminals 32 can be located at the center of the helical heating section 31 according to actual needs.

[0048] like Figure 4 and Figure 6As shown, in one embodiment, the distance L2 between the heating tube walls of two adjacent heating sections 31 satisfies: 10mm ≤ L2 ≤ 40mm. Here, L2 can be any value within the range of 10mm to 40mm, such as 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, or 40mm. When the heating section 31 is in a double helix shape, the distance L2 between the heating tube walls of two adjacent heating sections 31 and the distance L2 between the heating tube walls of two heating sections 31 within the same heating section 31 both satisfy 10mm ≤ L2 ≤ 40mm. Thus, L2 ≥ 10mm. Since the heating element 30 needs to be clamped and positioned by a fixture during manufacturing, and considering the thickness of the fixture and the need for space for handling, a small L2 would make it difficult to position the heating element 31 during manufacturing, potentially causing it to loosen and increasing the manufacturing difficulty. This also avoids localized overheating due to an excessively small L2. L2 ≤ 40mm. This avoids excessive bending of the heating element 31, which could lead to cracking and bursting during heating. It also avoids cold spots due to an excessively large L2, affecting the uniformity of heating the baking pan 20. Of course, in other embodiments, L2 can be set to less than 10mm or greater than 40mm depending on factors such as the size of the baking pan 20, the cross-sectional size of the heating element 31, and the heating power of the heating element 30.

[0049] like Figure 3 and Figure 5 As shown, the heating element 30 also includes a fixing piece 33 connected to the power connection terminal 32. The fixing piece 33 is fixed to the inner wall of the assembly cavity 11 by fasteners. The fasteners can be screws, bolts, or similar structures to ensure the stability and reliability of the connection between the fixing piece 33 and the inner wall of the assembly cavity 11. In this way, the power connection terminal 32 can be reliably fixed to the inner wall of the assembly cavity 11 by the fixing piece 33, preventing displacement or deformation of the heating element 30 due to vibration or temperature changes, which could lead to loosening or damage to the power connection terminal 32. This ensures a reliable electrical connection between the power connection terminal 32 and the power cord, improving safety. Furthermore, the fixing piece 33 is easy to install and remove, facilitating user disassembly and maintenance of the heating element 30.

[0050] like Figures 1 to 2As shown, in one embodiment, the housing assembly 10 includes an outer shell 13 and a reflector 14. The reflector 14 is disposed within the outer shell 13 and forms an assembly cavity 11 with the outer shell 13. The heating element 30 is fixed to the reflector 14. The reflector 14 is used to reflect the heat radiated by the heating element 30 towards the reflector 14 back to the baking pan 20, reducing heat loss, improving thermal efficiency, and saving energy. It can also help improve the temperature uniformity of the baking pan 20, thereby improving the heating effect and heating efficiency. Furthermore, the assembly cavity 11 formed by the reflector 14 and the outer shell 13 can also protect the heating element 30, preventing the heating element 30 from directly contacting other structures within the housing assembly 10, thus improving safety during use. Of course, in other embodiments, the heating element 30 can also be fixed to the outer shell 13 by multiple clamps. During assembly, the inner sidewall of each clamp is pressed tightly against the outer peripheral wall of the heating element, and then the clamp is fixed to the outer shell 13 by fasteners. The heating element 30 can also be directly fixed to the bottom wall of the baking pan 20 by clamps, casting, or other methods. As long as the stability and reliability of the contact between the top wall of the heating element 30 and the bottom wall of the baking pan 20 can be ensured, and the normal operation of other components in the shell assembly 10 is not affected, this utility model embodiment does not make specific limitations here.

[0051] like Figures 7 to 8 As shown, the reflector 14 is further provided with mounting holes 142, the fixing piece 33 is fixed to the reflector 14 by fasteners, the power terminal 32 is electrically connected to the power line through the mounting holes 142, and the mounting holes 142 facilitate user installation and positioning.

[0052] like Figure 1 As shown, in one embodiment, the baking pan 20 is detachably disposed in the assembly cavity 11. This facilitates the user's individual disassembly and cleaning of the baking pan 20, and also facilitates the disassembly and maintenance of the heating element 30 within the assembly cavity 11. Furthermore, the user can replace the baking pan 20 with one of different depths, functions, or materials according to actual needs, expanding the applicability of the grilling appliance. Of course, in other embodiments, the baking pan 20 may also be fixedly disposed in the assembly cavity 11 to ensure the stability and reliability of the connection between the baking pan 20 and the housing assembly 10.

[0053] like Figure 2 , Figure 7 and Figure 8As shown, for the spiral heating element 30, the heating section 31 is relatively long, and using multiple clamps for fixing is time-consuming and complex. While increasing the distance between two clamps to reduce clamp usage and assembly time might reduce the time required, it could also cause the heating element 30 to wobble after a period of use, affecting product quality. Therefore, this embodiment of the invention also provides a grilling appliance, including the aforementioned housing assembly 10 and heating element 30. The grilling appliance also includes an assembly assembly 40, which includes multiple fixing members 41 and multiple supporting members 42. The fixing members 41 are evenly distributed along the length of the heating section 31, and at least one supporting member 42 is provided between adjacent fixing members 41. The supporting member 42 protrudes from the reflector 14, one end of the fixing member 41 is fixed to the reflector 14, and the other end is fixedly connected to the heating section 31. The heating element 30 overlaps the end of the supporting member 42 facing away from the reflector 14.

[0054] In the aforementioned grilling appliance, multiple fixing members 41 evenly distributed along the length of the heating section 31 provide a sufficient number of support points for the heating section 31, preventing it from deforming or saging during heating. This ensures the stability and reliability of the heating element 30 during long-term use and keeps the top wall of the heating element 30 in contact with the bottom wall of the baking pan 20, ensuring uniform heating of the baking pan 20. Furthermore, the fixing members 41 and the support members 42 support the heating element 30, creating a gap between it and the reflector 14, which facilitates more even heat radiation and transfer to the baking pan 20, preventing localized overheating. Simultaneously, the heating section 31 only needs to be connected to the fixing members 41, simplifying the assembly process while ensuring the stability of the heating element 30. This makes the installation process simple and convenient, thereby reducing assembly time and production costs.

[0055] like Figures 7 to 9As shown, in one embodiment, the fixing member 41 includes a fixing part 411 and a clamping part 412 protruding from the fixing part 411 toward the direction away from the reflector 14. The fixing part 411 is fixed to the reflector 14, and the clamping part 412 clamps at least partially the heating section 31. Specifically, the fixing part 411 can be detachably fixed to the reflector 14 by fasteners such as screws and bolts, or it can be fixed to the reflector 14 by non-detachable methods such as welding or gluing, as long as the stability and reliability of the connection between the fixing member 41 and the reflector 14 can be ensured. The clamping part 412 fixes the heating section 31 by clamping, allowing the user to quickly fix the heating section 31 in the clamping part 412, thereby further simplifying the assembly process and improving assembly efficiency; at the same time, the clamping part 412 can also ensure the stability and reliability of the connection between the heating section 31 and the fixing member 41, avoiding shaking or falling off, and ensuring the long-term stability of the position of the heating tube 30. Of course, in other embodiments, the fixing member 41 can also be a clamp, buckle or other fixing structure that can stably fix the heating section 31 to the reflector 14. This embodiment of the present invention does not make specific limitations here.

[0056] like Figures 8 to 9 As shown, the fixing member 41 further includes a positioning part 413, which protrudes from the fixing part 411 toward the reflector 14. The reflector 14 has a positioning hole 141, and the positioning part 413 is inserted into the positioning hole 141. Specifically, when the fixing part 411 is detachably fixed to the reflector 14 by fasteners such as screws and bolts, the fixing part 411 has a first mounting hole 414, and the reflector 14 has a corresponding second mounting hole 143. After the positioning part 413 is inserted into the positioning hole 141, the first mounting hole 414 and the second mounting hole 143 are aligned, thereby achieving a pre-positioning function. In this way, each fixing member 41 has a unique and accurate installation position, so that the user can install and position the fixing member 41 and the heating element 30; at the same time, it also prevents the fixing member 41 from shifting or rotating during assembly or use, ensuring an accurate and reliable connection between the heating element 30, the fixing member 41, and the reflector 14. In the illustrated embodiment, the positioning hole 141 and the positioning part 413 are strip-shaped structures that can cooperate with each other, further preventing the fixing member 41 from rotating relative to the reflector 14 during assembly. Of course, the positioning hole 141 and the positioning part 413 can also be set to other regular or irregular shapes such as circles, squares, and triangles according to actual needs, and this embodiment of the present invention does not impose specific limitations here.

[0057] like Figure 2 and Figure 9As shown, the clamping part 412 is a groove with an opening. The opening of the groove is deformable, and the arc α of the groove clamping the heating section 31 is not less than 180 degrees. Here, α can be any angle greater than 180 degrees and less than 360 degrees, such as 180 degrees, 185 degrees, 190 degrees, 195 degrees, or 200 degrees, as long as it ensures that the heating section 31 can be inserted into the groove through the opening. The deformable opening of the groove allows it to be smaller than the cross-sectional diameter of the heating section 31. The user can press the heating section 31 to insert it into the groove. After the heating section 31 is inserted, the opening of the groove returns to its original position under its own elasticity to enclose the heating section 31, thus ensuring reliable clamping while facilitating assembly. The arc α of the groove clamping heating section 31 is not less than 180 degrees, so that the groove can wrap the heating section 31 in a structure that is more than half-enclosed, increasing the contact area between the heating section 31 and the clamping part 412, thereby improving the stability and reliability of the clamping part 412 clamping the heating section 31 and preventing the heating section 31 from shaking or falling off.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
