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 is usually a heating tube. Currently, the heating tube is mainly fixed to the housing by multiple clamps. During assembly, the inner wall of each clamp needs to be tightly pressed against the outer wall of the heating tube, and then the clamp is fixed to the housing by fasteners. The assembly method is complicated.

[0003] Especially for spiral heating elements, which are relatively long, the above-mentioned process is time-consuming and the assembly method is complex. If the distance between the two clamps is increased to reduce the number of clamps used and thus reduce assembly time, the heating element may wobble after a period of use, affecting product quality. Utility Model Content

[0004] Therefore, it is necessary to provide a grilling appliance that simplifies the assembly process while ensuring the stability of the heating element.

[0005] This utility model provides a grilling appliance, comprising: a shell assembly, the shell assembly including an outer shell and a reflector, the reflector being disposed within the outer shell and forming an assembly cavity with the outer shell; a heating element disposed within the assembly cavity and fixed to the reflector, the heating element including a heating section and an electrical terminal disposed at the end of the heating section, the heating section being spiral-shaped; and an assembly assembly including multiple fixing members and multiple supporting members, the multiple fixing members being evenly distributed along the length direction of the heating section, at least one supporting member being disposed between each two adjacent fixing members, the supporting member protruding from the reflector, one end of the fixing member being fixed to the reflector, and the other end being fixedly connected to the heating section, the heating element overlapping the end of the supporting member away from the reflector.

[0006] In the aforementioned grilling appliance, multiple fixing components evenly distributed along the length of the heating section provide support for the heating section. Combined with auxiliary support components, this provides sufficient support points to prevent deformation, collapse, or shaking during heating, ensuring the stability and reliability of the heating element in long-term use. Furthermore, it ensures that the top wall of the heating element remains in contact with the bottom wall of the grill pan, guaranteeing uniform heating. The fixing and support components also support the heating element, creating a gap between it and the reflector, which facilitates more even heat radiation and transfer to the grill pan, preventing localized overheating. Simultaneously, the heating section only needs to be connected to the fixing components, simplifying the assembly process while ensuring the stability of the heating element. This makes installation simple and convenient, reducing assembly time and production costs.

[0007] In one embodiment, the fixing member includes a fixing portion and a clamping portion protruding from the fixing portion toward a direction away from the reflector, the fixing portion being fixed to the reflector, and the clamping portion at least partially clamping the heating section.

[0008] This design allows users to quickly clamp and fix the heating section within the clamping part, thereby simplifying the assembly process and improving assembly efficiency. At the same time, the clamping part ensures the stability and reliability of the connection between the heating section and the fixing part, preventing shaking or falling off and ensuring the long-term stability of the heating element position.

[0009] In one embodiment, the fixing member further includes a positioning part, which protrudes from the fixing part toward the direction close to the reflector. The reflector is provided with a positioning hole, and the positioning part is inserted into the positioning hole.

[0010] This design ensures that each fastener has a unique and accurate installation position, making it easy for users to install and position the fastener and heating element; it also prevents the fastener from shifting or rotating during assembly or use, ensuring an accurate and reliable connection between the heating element, fastener, and reflector.

[0011] In one embodiment, the clamping part is a groove with an opening, the opening of the groove is deformable, and the arc of the groove clamping the heating section is not less than 180 degrees.

[0012] This design increases the contact area between the heating section and the clamping part, improving the stability and reliability of the clamping part in holding the heating section and preventing the heating section from shaking or falling off.

[0013] In one embodiment, the heating element further includes a fixing piece connected to the power terminal, the fixing piece being fixed to the reflector by fasteners.

[0014] 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.

[0015] In one embodiment, the reflector is further provided with a temperature controller, the heating section has a central region, the temperature sensing end of the temperature controller is located in the central region, and the distance from the temperature sensing end of the temperature controller to the inner wall of the heating section surrounding the central region is L, which satisfies: 10mm≤L≤45mm.

[0016] This configuration allows the temperature controller's sensing end to directly perceive the heating temperature of the core heating area of ​​the baking pan by the heating element; it prevents the temperature controller's sensing end from being too close to the heating element if L is too small, causing it to sense a temperature far higher than the actual working temperature of the baking pan, thus affecting the accuracy of the temperature measurement results; at the same time, it prevents the temperature controller's sensing end from being too large, resulting in a cold zone in the central area, which would prevent the heating element from effectively sensing the heating temperature of the baking pan, affecting the uniformity and accuracy of the heating of the baking pan by the heating element.

[0017] In one embodiment, the grilling appliance further includes a grill pan disposed in the assembly cavity, the bottom wall of the grill pan being in contact with the heating section.

[0018] This design allows the heat generated by the heating element to be transferred directly and quickly to the baking pan, shortening the preset time and improving heating efficiency. Furthermore, the top wall of the heating element forms a line contact with the bottom wall of the baking pan, allowing the heating element to fit better with the baking pan, reducing the requirements for the flatness of the bottom wall of the baking pan and simplifying the processing technology.

[0019] In one embodiment, the distance between the center point of the temperature sensing end of the temperature controller and the inner wall of the heating section that forms the central region is L1, which satisfies 35mm≤L1≤100mm.

[0020] 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.

[0021] In one embodiment, all the electrical terminals are located on the outer periphery of the spiral heating section; or one electrical terminal is located at the center of the spiral heating section, and the other electrical terminal is located on the outer periphery of the spiral heating section.

[0022] With this configuration, all the power terminals are located on the outer periphery of the heating section, making it convenient for users to wire the cables on the outside of the heating element, which makes the assembly process simpler and safer. The two power terminals are arranged separately to avoid the power terminals taking up too much space and causing local low temperature areas in the heating element. At the same time, it avoids mutual interference between the cables connected to the two power terminals, making it easier for users to wire the cables.

[0023] In one embodiment, the distance L2 between the heating tube walls of two adjacent heating sections satisfies: 10mm≤L2≤40mm.

[0024] 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.

[0041] The heating element in grilling appliances is typically a heating element. Currently, the heating element is mainly fixed to the housing using multiple clamps. During assembly, the inner wall of each clamp must be tightly pressed against the outer wall of the heating element, and then the clamps are secured to the housing with fasteners. This assembly method is complex. This is especially true for spiral heating elements, which are often quite long, making the process time-consuming and complicated. While increasing the distance between clamps to reduce clamp usage and assembly time could reduce assembly time, it might cause the heating element to wobble after a period of use, affecting product quality.

[0042] To solve the above problems, such as Figures 1 to 9 As shown, this utility model provides a grilling appliance that simplifies the assembly process while ensuring the stability of the heating element.

[0043] like Figure 2 , Figure 7 and Figure 8 As shown, specifically, the grilling appliance includes a housing assembly 10, a heating element 30, and an assembly assembly 40, wherein: the housing assembly 10 includes an outer shell 13 and a reflector 14, the reflector 14 is disposed inside the outer shell 13 and forms an assembly cavity 11 with the outer shell 13; the heating element 30 is disposed inside the assembly cavity 11 and fixed to the reflector 14, the heating element 30 includes a heating section 31 and an electrical terminal 32 disposed at the end of the heating section 31, the heating section 31 is spiral-shaped; the assembly assembly 40 includes multiple fixing members 41 and multiple supporting members 42, the multiple fixing members 41 are evenly distributed along the length direction of the heating section 31, and at least one supporting member 42 is provided between each two 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 away from the reflector 14.

[0044] In the grilling appliance provided in this embodiment of the utility model, the reflector 14 is used to reflect the heat radiated by the heating element 30 toward the reflector 14 back to the grill pan 20, thereby reducing heat loss, improving the utilization efficiency of heat energy, and saving energy. At the same time, it can also help improve the temperature uniformity of the grill 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, prevent the heating element 30 from directly contacting other structures inside the shell assembly 10, and improve the safety of use. By fixing and supporting the heating section 31 with multiple fasteners 41 evenly distributed along its length, and with the auxiliary support of the support 42, sufficient support points can be provided for the heating section 31 to prevent deformation, collapse, or shaking during heating. This ensures the stability and reliability of the heating tube 30 during long-term use and keeps the top wall of the heating tube 30 in contact with the bottom wall of the baking pan 20, ensuring uniform heating of the baking pan 20 by the heating tube 30. Furthermore, the fasteners 41 and the support 42 support the heating tube 30, creating a certain gap between the heating tube 30 and the reflector 14, which facilitates more even radiation and transfer of heat to the baking pan 20 and avoids local overheating. At the same time, the heating section 31 only needs to be connected to the fasteners 41, which simplifies the assembly process while ensuring the stability of the heating tube 30, making the installation process simple and convenient, thereby reducing assembly time and production costs.

[0045] like Figure 1 , Figure 4 and Figure 6 As shown, the grilling appliance also includes a grill pan 20, which is disposed within the assembly cavity 11; a heating element 30 has a central region 311, and the heating element 30 is disposed within the assembly cavity 11. When the grill pan 20 is placed in the assembly cavity 11, the top wall of the heating element 30 contacts the bottom wall of the grill pan 20; wherein, 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 section 31 surrounding the central region 311 is L, and satisfies: 10mm≤L≤45mm. Wherein, L can be any value within the range of 10mm to 45mm, such as 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, etc.

[0046] It should be noted that the central region 311 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.

[0047] In the aforementioned grilling appliance, the heating element 30 is in direct contact with the baking pan 20, eliminating the need for a 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.

[0048] like Figure 4 and Figure 6 As shown, in one embodiment, the distance L1 between the center point of the temperature sensing end of the temperature controller 12 and the inner wall of the heating section 31 that forms 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.

[0049] like Figure 3 and Figure 5 As shown, the heating element 30 includes a heating section 31 and electrical terminals 32 disposed at both ends 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 electrical terminals 32 are 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.

[0050] 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.

[0051] 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.

[0052] like Figures 5 to 6As 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.

[0053] like Figure 4 and Figure 6 As 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.

[0054] like Figure 3 and Figure 5As 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.

[0055] 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.

[0056] 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.

[0057] like Figures 7 to 9 As 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.

[0058] 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.

[0059] like Figure 2 and Figure 9 As 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.
