Description

Technical Field

[0001] This application belongs to the field of kitchen appliance technology, specifically relating to a grill. Background Technology

[0002] Existing grills generally consist of an upper grill pan assembly and a lower grill pan assembly. The upper grill pan assembly includes a lid and an upper grill pan, while the lower grill pan assembly includes a base, a lower grill pan, a thermostat, and a fuse. When the grill is in normal working condition, the temperature of the fuse surface will not exceed its set value during cooking to ensure the normal operation of the grill's cooking process. When the grill's temperature rises rapidly due to a short circuit in the thermostat or other abnormalities, the fuse needs to detect this abnormal temperature rise promptly and disconnect in time to ensure the safe use of the grill.

[0003] With the increasing demand for diverse food cooking methods, some users want to use a grill to cook foods that require water or have a high moisture content, such as pan-fried buns. When cooking these foods, the grill pan heats up slowly due to the cooling effect of the water, causing the heating element to work continuously for a long time. During this process, the heat radiated to the fuse increases, and the surface temperature of the fuse continues to rise. Eventually, the fuse exceeds the preset temperature value and trips. This tripping is irreversible. Once the fuse trips, the grill will be in an open circuit state and cannot work, making it impossible to cook the pan-fried buns.

[0004] Therefore, existing grills are limited to traditional cooking methods such as frying and grilling, which cannot meet the personalized needs of users and result in a poor user experience. Utility Model Content

[0005] This application provides a grill to solve the technical problem that existing grills have functional limitations and cannot simultaneously ensure that the fuse does not open during the cooking of water-rich foods such as pan-fried buns, but that the fuse must disconnect in time in case of a short circuit due to abnormal conditions.

[0006] The technical solution adopted in this application is as follows:

[0007] A grill includes a base and a baking pan disposed on one side of the base. A heating device is fixed on the side of the base facing the baking pan. The base includes an inner shell and an outer shell. An internal cavity is formed between the outer shell and the inner shell. A fuse is disposed in the internal cavity. The outer shell protrudes in a direction away from the inner shell at a position opposite to the fuse to form a bulge. A heat dissipation cavity is provided inside the bulge.

[0008] The fuse in this application is located within an internal cavity formed by the outer shell and inner shell. The inner shell acts as the first barrier against heat radiation, reducing heat radiation to the fuse during operation of the heating element, thereby lowering the fuse's temperature rise. Even when cooking water-rich foods like pan-fried buns, and even with prolonged operation of the heating element, the fuse's temperature rise rate is relatively slowed due to the presence of the inner shell, preventing improper tripping and allowing the cooking process to proceed normally. This application also features a protruding bulge on the outer shell opposite the fuse, extending away from the inner shell. This bulge forms a heat dissipation cavity, increasing the distance between the fuse and the outer shell, facilitating heat dissipation, and slowing the rate of temperature rise on the fuse's surface. This allows the fuse to simultaneously meet the requirements of not tripping during the cooking of water-rich foods like pan-fried buns, but also tripping promptly in case of a short circuit due to abnormal conditions. This expands the functionality of the grill and enhances the user experience.

[0009] The convex bulge is provided with a number of heat dissipation holes that communicate with the heat dissipation cavity.

[0010] This technical solution, by opening heat dissipation holes on the convex bulge that communicate with the heat dissipation cavity, allows the heat inside the cavity to continuously radiate outward, reducing the temperature rise inside the cavity and thus reducing the temperature rise of the fuse. Moreover, the heat dissipation holes provide an exchange path for the introduction of cold air from the outside. The hot air inside the cavity and the cold air outside continuously exchange heat, further slowing down the temperature rise rate of the fuse surface. This allows it to adapt to the needs of cooking processes such as pan-frying dumplings, maintaining a moderate fuse surface temperature within a safe temperature range without tripping, thereby ensuring the normal operation of the cooking process.

[0011] At least a portion of the heat dissipation holes are positioned opposite the fuse.

[0012] This technical solution, by placing some heat dissipation holes directly opposite the fuse, can further improve the heat dissipation efficiency of the fuse and reduce the rate of temperature rise of the fuse.

[0013] The convex bulge includes a bottom wall and a side wall connecting the bottom wall and the outer shell. The side wall has a first end connected to the outer shell and a second end connected to the bottom wall. The side wall is inclined from the first end to the second end so that the convex bulge has an flared structure that gradually expands from the second end to the first end.

[0014] This technical solution, by setting the convex hull as an flared structure that gradually expands from the second end to the first end, can further increase the area of ​​the heat dissipation cavity within a limited structural space, improve the heat dissipation efficiency of the fuse, and further reduce the temperature rise rate of the fuse, so that it can match the needs of different cooking programs of the grill.

[0015] The sidewalls include a first sidewall and a second sidewall located on two opposite sides of the convex hull. The height of the first end of the first sidewall is different from the height of the first end of the second sidewall, so that the convex hull has an asymmetrical flared structure.

[0016] This technical solution enhances the fluid flow performance within the heat dissipation cavity by designing the convex bulge as an asymmetrical flared structure. This further improves the efficiency of heat exchange between hot and cold air, reduces the temperature rise of the fuse, and keeps the surface temperature of the fuse body in a relatively low and stable thermal equilibrium state. This ensures that during cooking processes such as pan-frying buns, the surface temperature of the fuse remains within a safe temperature range and does not trip, thus guaranteeing the normal operation of the grill.

[0017] Both the first sidewall and the second sidewall are provided with heat dissipation holes extending from the first end to the second end, and the heat dissipation holes are in communication with the heat dissipation cavity.

[0018] This technical solution, by arranging the heat dissipation holes to extend from the first end to the second end, can create a larger heat dissipation area in the vertical direction, which is beneficial for enhancing the heat exchange circulation inside and outside the heat dissipation cavity, thereby helping to dissipate heat from the fuse. Furthermore, the higher position of the first end of either the first or second sidewall means that the heat dissipation holes on either sidewall are closer to the fuse, further improving the heat dissipation effect and reducing the rate of temperature rise of the fuse.

[0019] The outer shell has a protruding support leg on the side facing away from the inner shell. The bottom surface of the protrusion is higher than the bottom surface of the support leg to form a heat dissipation gap between the bottom surface of the protrusion and the bottom surface of the support leg on the same horizontal plane.

[0020] This technical solution creates a heat dissipation gap below and around the convex bulge by setting the bottom surface of the bulge higher than the bottom surface of the support leg. Natural air convection is used to dissipate heat from the heat dissipation cavity and the fuse located above it. Utilizing the principle that hot air rises and cold air sinks, the airflow within the heat dissipation gap can carry away more heat from the heat dissipation cavity, thus improving heat dissipation efficiency. Furthermore, the presence of the heat dissipation gap reduces thermal resistance in the heat conduction path within the heat dissipation cavity, allowing heat to be transferred more effectively to the surrounding air, further enhancing heat dissipation performance.

[0021] The bottom of the baking pan has a structure that is high in the middle and low around the perimeter, and the fuse is positioned directly opposite the low perimeter area of ​​the baking pan.

[0022] Due to the arrangement of heating elements in the heating device, the temperature in the center of the baking pan is generally higher than that at the edges. Uneven heating during operation can easily cause deformation of the pan. This technical solution designs the bottom of the baking pan with a higher center and lower perimeter, reducing the probability of heat deformation and extending its lifespan. Placing the fuse directly opposite the lower perimeter of the baking pan slows its temperature rise, preventing it from tripping during the boiling process and ensuring the normal operation of the cooking process.

[0023] The heating device includes a fixed plate and a heating tube fixed to the fixed plate. The heating tube is provided with a wiring terminal, and the fuse is arranged close to the wiring terminal.

[0024] The temperature at the heating element terminal is the lowest compared to the rest of the heating element. Therefore, placing the fuse close to the terminal can reduce the heat radiation from the rest of the heating element to the fuse, thus slowing down the rate of temperature rise of the fuse and making it suitable for different cooking programs in the grill.

[0025] The wiring terminal passes through the inner housing and extends into the internal cavity, and the heat dissipation cavity is in communication with the internal cavity.

[0026] In this technical solution, the wiring terminals extend through the inner shell into the internal cavity. The inner shell itself has a certain blocking effect on the heat radiation of the heating device. Placing the wiring terminals in the internal cavity can further reduce the temperature rise of the wiring terminals. The fuse is arranged close to the wiring terminals, thereby reducing the temperature rise rate of the fuse. Attached Figure Description

[0044] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0045] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0049] like Figure 1 , Figure 2 and Figure 4 As shown, a grill includes a base and a grill pan 9 disposed on one side of the base. A heating device 7 is fixed on the side of the base facing the grill pan 9. The base includes an inner shell 4 and an outer shell 5. An internal cavity 8 is formed between the outer shell 5 and the inner shell 4. A fuse 6 is provided in the internal cavity 8. The outer shell 5 protrudes in a direction away from the inner shell 4 at a position opposite to the fuse 6 to form a bulge 51. A heat dissipation cavity 515 is provided in the bulge 51.

[0050] The fuse 6 in this application is located within the internal cavity 8 formed by the outer shell 5 and the inner shell 4. The inner shell 4 acts as the first barrier against heat radiation, reducing heat radiation from the heating device 7 to the fuse 6 during operation. This reduces the temperature rise of the fuse 6, ensuring that even when cooking water-rich foods like pan-fried buns, the temperature rise rate of the fuse 6 is relatively slow due to the presence of the inner shell 4, even if the heating device 7 operates continuously for extended periods. This prevents improper disconnection of the fuse 6 during the cooking process, allowing the cooking procedure to proceed normally. This application also features a protrusion 51 protruding away from the inner shell 4 at a position opposite the outer shell 5 and the fuse 6. The protrusion 51 forms a heat dissipation cavity 515, increasing the distance between the fuse 6 and the outer shell 5. This facilitates heat dissipation from the fuse 6 and slows the rate of temperature rise on its surface. This allows the fuse to simultaneously meet the requirements of not disconnecting during the cooking of water-rich foods like pan-fried buns, but also disconnecting promptly in case of a short circuit due to abnormal conditions. This expands the functionality of the grill and enhances the user experience.

[0051] Grills typically have an upper grilling pan assembly and a lower grilling pan assembly. Existing grills can have their upper and lower grilling pan assemblies operate independently or together to cook food. Generally, for cooking processes like pan-frying dumplings, both the dumplings and water are placed in the lower grilling pan. Therefore, in one embodiment of this application, the base and the grilling pan 9 refer to a portion of the lower grilling pan assembly 2 of the grill. However, it is not excluded that the upper grilling pan assembly 1 of the grill can also perform cooking functions for watery foods like pan-frying dumplings when flipped to a flat position relative to the lower grilling pan assembly 2. Therefore, in another embodiment of this application, the base and the grilling pan 9 refer to a portion of the upper grilling pan assembly 1 of the grill. Of course, in yet another embodiment, both the upper grilling pan assembly 1 and the lower grilling pan assembly 2 of the grill can adopt the base and grilling pan 9 structure described in this application.

[0052] As a preferred embodiment of this application, such as Figure 3 As shown, the convex bulge 51 has several heat dissipation holes 514 communicating with the heat dissipation cavity 515. By opening heat dissipation holes 514 on the convex bulge 51 communicating with the heat dissipation cavity 515, the heat inside the internal cavity 8 can be continuously radiated outward, reducing the temperature rise inside the internal cavity 8, thereby reducing the temperature rise of the fuse. Moreover, the heat dissipation holes 514 provide an exchange path for the introduction of cold air from the outside. The hot air inside the internal cavity 8 and the cold air from the outside continuously exchange heat, further slowing down the temperature rise rate of the fuse 6 surface, so that it can adapt to the needs of cooking processes such as pan-frying dumplings. The surface temperature of the fuse 6 can be kept within a safe temperature range without tripping, thus ensuring the normal operation of the cooking process.

[0053] This embodiment does not limit the location of the heat dissipation hole 514. Preferably, such as... Figure 2 and Figure 3 As shown, at least some of the heat dissipation holes 514 are directly opposite the fuse 6. By positioning some of the heat dissipation holes 514 directly opposite the fuse 6, the heat dissipation efficiency of the fuse 6 can be further improved, and the rate of temperature rise of the fuse 6 can be reduced.

[0054] Furthermore, heat dissipation holes 514 are provided on the bottom wall 511, side wall, and the connection between the bottom wall 511 and the side wall of the convex bulge 51 to further improve the heat exchange efficiency inside and outside the heat dissipation cavity 515.

[0055] This embodiment does not limit the shape of the heat dissipation hole 514, which can be a round hole, a square hole, a long hole, an arc hole, etc.

[0056] The structure of the convex hull 51 in this application can adopt any of the following embodiments:

[0057] Implementation Method 1: This implementation method is not illustrated. In this implementation method, the convex hull includes a bottom wall and a side wall connecting the bottom wall and the outer shell. The side wall has a first end connected to the outer shell and a second end connected to the bottom wall. The side wall extends vertically from the first end to the second end so that the size of the convex hull remains consistent from the first end to the second end.

[0058] Implementation Method Two: (e.g.) Figure 2 and Figure 4 As shown, the convex bulge 51 includes a bottom wall 511 and a side wall connecting the bottom wall 511 and the outer shell 5. The side wall has a first end connected to the outer shell 5 and a second end connected to the bottom wall 511. The side wall is inclined from the first end to the second end, so that the convex bulge 51 has a flared structure that gradually expands from the second end to the first end. In this second embodiment, by setting the convex bulge 51 as a flared structure that gradually expands from the second end to the first end, the area of ​​the heat dissipation cavity 515 can be further increased within a limited structural space, thereby improving the heat dissipation efficiency of the fuse 6 and further reducing the temperature rise rate of the fuse 6, making it suitable for the needs of different cooking programs in the grill. In addition, the flared structure can increase the surface area of ​​the convex bulge 51, and since heat dissipation efficiency is proportional to heat dissipation area, a larger surface area of ​​the convex bulge 51 means that more heat can be dissipated to the surrounding environment. Therefore, this second embodiment can further improve the heat dissipation efficiency.

[0059] The structural details of the flared structure in this second embodiment can adopt any of the following embodiments:

[0060] Example 1: This example 1 is not illustrated. In this example 1, the sidewalls include a first sidewall and a second sidewall located on two opposite sides of the convex hull. The height of the first end of the first sidewall is the same as the height of the first end of the second sidewall, so that the convex hull has a symmetrical flared structure.

[0061] Example 2: Figure 2 As shown, the sidewalls include a first sidewall 512 and a second sidewall 513 located on two opposite sides of the convex 51. The height of the first end of the first sidewall 512 is different from the height of the first end of the second sidewall 513, so that the convex 51 has an asymmetrical flared structure. By setting the convex 51 as an asymmetrical flared structure, the fluid flow performance in the heat dissipation cavity 515 can be enhanced, further improving the efficiency of hot and cold air heat exchange, reducing the temperature rise of the fuse 6, and keeping the surface temperature of the fuse 6 in a relatively low and stable thermal equilibrium state. This ensures that during cooking processes such as pan-frying buns, the surface temperature of the fuse 6 can always be kept within a safe temperature range and will not trip, thus ensuring that the grill can work normally.

[0062] Furthermore, such as Figure 3 As shown, both the first sidewall 512 and the second sidewall 513 have heat dissipation holes 514 extending from the first end to the second end, and the heat dissipation holes 514 communicate with the heat dissipation cavity 515. By setting the heat dissipation holes 514 to extend from the first end to the second end, a larger heat dissipation area can be formed in the vertical direction, which is beneficial to enhance the heat exchange circulation inside and outside the heat dissipation cavity 515, thereby helping to dissipate heat from the fuse 6. In addition, the first end of one of the first sidewalls 512 and 513 is located at a higher position, which means that the heat dissipation hole 514 of one of the first sidewalls 512 and 513 is closer to the fuse 6, further improving the heat dissipation effect of the fuse 6 and reducing the temperature rise rate of the fuse 6.

[0063] As a preferred embodiment of this application, such as Figure 1 and Figure 4 As shown, the outer shell 5 has a protruding support leg 52 on the side facing away from the inner shell 4. The bottom surface of the protrusion 51 is higher than the bottom surface of the support leg 52, forming a heat dissipation gap between the bottom surface of the protrusion 51 and the bottom surface of the support leg 52. In this embodiment, by setting the bottom surface of the protrusion 51 higher than the bottom surface of the support leg 52, a heat dissipation gap is formed below and around the protrusion 51. Natural air convection is used to dissipate heat from the heat dissipation cavity 515 and the fuse 6 located above the heat dissipation cavity 515. Utilizing the principle that hot air rises and cold air sinks, the airflow in the heat dissipation gap can carry away more heat from the heat dissipation cavity 515, thereby improving heat dissipation efficiency. Furthermore, the presence of the heat dissipation gap can reduce the thermal resistance in the heat conduction path within the heat dissipation cavity 515, allowing heat to be transferred more effectively to the surrounding air, thus improving heat dissipation performance.

[0064] Due to the arrangement of heating elements in the heating device, the temperature in the center of the baking pan is generally higher than that at the edges. Uneven heating during operation can cause deformation of the baking pan. Therefore, as a preferred embodiment of this application, such as... Figure 6 As shown, the bottom of the baking pan 9 has a structure that is higher in the middle and lower around the edges, which can reduce the probability of the baking pan 9 deforming due to heat and extend its service life. Furthermore, the fuse 6 is positioned directly opposite the lower area around the edge of the baking pan 9. This design can reduce the rate of temperature rise of the fuse 6, thereby preventing the fuse 6 from tripping during the boiling process of the grill, ensuring the normal operation of the cooking program.

[0065] The base in this application is also equipped with a snap-on thermostat 3, which is positioned directly opposite the central area of ​​the baking pan 9 to detect the temperature of the central area of ​​the baking pan 9. The central area of ​​the baking pan 9 has a high temperature, making it prone to drying out during the pan-frying process. The water in the peripheral area of ​​the baking pan 9 is dried out last. During this drying process, the snap-on thermostat 3 repeatedly trips as the temperature of the central area of ​​the baking pan 9 rises. During this process, the heating device does not operate continuously, and the temperature inside the baking pan 9 remains relatively stable, preventing continuous increases. This keeps the surface temperature of the fuse 6 in a dynamic equilibrium and within the set tripping temperature range, ensuring that the fuse 6 does not trip unintentionally due to boiling water, thus guaranteeing the normal operation of the cooking process.

[0066] As a preferred embodiment of this application, such as Figure 1 , Figure 4 and Figure 5 As shown, the heating device 7 includes a fixed plate 71 and a heating element 72 fixed to the fixed plate 71. The heating element 72 is provided with a terminal 721, and a fuse 6 is arranged near the terminal 721. The temperature at the terminal 721 of the heating element 72 is the lowest compared to the temperature of the rest of the heating element 72. Therefore, arranging the fuse 6 near the terminal 721 can reduce the heat radiation from the temperature rise of the rest of the heating element 72 to the fuse 6, reduce the temperature rise rate of the fuse 6, and make it suitable for the needs of different cooking programs of the grill.

[0067] Furthermore, the terminal 721 passes through the inner housing 4 and extends into the internal cavity 8, with the heat dissipation cavity 515 communicating with the internal cavity 8. In this technical solution, the terminal 721 passes through the inner housing 4 and extends into the internal cavity 8. The inner housing 4 itself has a certain blocking effect on the heat radiation of the heating device 7. Placing the terminal 721 inside the internal cavity 8 can further reduce the temperature rise of the terminal 721. The fuse 6 is arranged close to the terminal 721, thereby reducing the temperature rise rate of the fuse 6.

[0068] Preferably, the fuse 6 is detachably mounted near the terminal block 721 so that it can be removed and replaced after tripping.

[0069] The grill includes an upper grill pan assembly 1 and a lower grill pan assembly 2, which are pivotally connected to each other, giving the grill a pivot side and an operating side away from the pivot side. The operating side refers to the side where the user opens the upper grill pan assembly 1 during or after cooking to flip or remove food. When the upper grill pan assembly 1 is opened during cooking, hot air from inside the grill quickly escapes along the operating side, resulting in a high ambient temperature around the operating side. Therefore, as a preferred embodiment of this application, such as... Figure 1 As shown, the fuse 6 is positioned near the pivot side. This arrangement ensures a relatively mild ambient temperature at the location of the convex 51, which aids in heat dissipation from the convex 51 and further reduces the rate of temperature rise of the fuse 6.
