Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a grilling machine. Background Technology

[0002] Patent CN218943037U discloses a grill, including a housing, a heating element, and a grill pan. The heating element is disposed between the housing and the grill pan, and includes a heating plate and a heating tube, which are integrally formed. A mounting groove is provided on the side of the heating plate facing the grill pan, and the heating tube is disposed within the mounting groove so that at least a portion of the heating tube is in contact with the grill pan. By positioning the heating tube on the side of the heating plate facing the grill pan, the heat utilization rate of the heating tube is improved.

[0003] Existing technologies typically employ a casting process to integrate the heating plate and heating element. Specifically, the heating element is first placed in a mold, and then casting material for the heating plate is injected into the mold and allowed to solidify, thus forming the heating assembly. However, during the injection process, the casting material may splash, causing solidified material residue to remain on the heating surface of the heating element exposed in the mounting groove, forming protrusions. This not only hinders the flatness of the heating surface, leading to poor adhesion between the heating element and the baking plate and reduced heat transfer efficiency, but also causes uneven heat conduction at the protruding areas.

[0004] The applicant intends to replace the casting process with die casting to solve the aforementioned problems. Specifically, a heating plate with an installation groove is first provided, and then the heating tube is die-cast into the installation groove to form a heating assembly. During further research, the applicant discovered that heating plates are mostly produced by stamping, resulting in relatively thin walls. The heating tube is embedded into the installation groove by pressing. Due to inherent manufacturing errors in both the heating tube and the heating plate, they cannot be pressed together according to the pre-set assembly relationship during the assembly process. During die casting, the heating tube itself can deform to adapt to the installation groove, and the heating plate also typically undergoes axial deformation under pressure, bulging upwards. This results in incomplete contact between the heating plate and the baking tray, leading to poor adhesion and uneven heating of the baking tray. Utility Model Content

[0005] This invention provides a grilling machine to solve the problem that during the die-casting process of the heating element and the heating plate, the heating plate deforms and the fit with the grilling plate is poor, resulting in poor heating uniformity of the grilling plate.

[0006] The technical solution adopted by this utility model is as follows: This utility model provides a grill, including a shell, a heating component and a grilling pan. The heating component is located between the shell and the grilling pan. The heating component includes a heating plate and a heating tube. The heating plate has a mounting groove on the side facing the grilling pan. The heating tube is die-cast in the mounting groove. The heating plate also has a pressure relief groove. The pressure relief groove is in the same direction as the recess of the mounting groove on the heating plate. The pressure relief groove is located on the outer ring and / or inner ring of the mounting groove.

[0007] The grill provided by this utility model features an installation groove on the heating plate, into which the heating tube is die-cast to efficiently transfer heat. A pressure relief groove on the heating plate provides a pressure relief space. During the die-casting process, the heating tube exerts radial pressure on the groove wall. Due to the axial force exerted on the heating plate by the upper and lower die-casting molds, the axial deformation force is converted into radial pressure. This pressure is then transmitted radially along the heating plate to the pressure relief groove. Since the pressure relief groove and the installation groove have the same concave direction on the heating plate (i.e., their openings face the same direction), the pressure is released within the pressure relief space of the groove, preventing pressure accumulation to the point of causing axial deformation due to internal structural damage. Furthermore, because the pressure relief groove is located on the outer and / or inner ring of the installation groove, the stress on the heating plate under pressure is distributed along the path of the groove and released within its pressure relief space, reducing high stress concentration in a single area and further preventing axial deformation of the heating plate. Therefore, the pressure relief groove allows the extrusion pressure of the heating plate to be released radially, preventing the heating plate from bulging due to axial deformation under pressure. This improves the flatness of the heating plate, enhances the fit between the heating plate and the baking pan, and results in more uniform heat transfer.

[0008] In a preferred embodiment, the pressure relief groove is a through groove that extends continuously following the shape of the mounting groove and has two opposing groove walls, with a deformable connector connecting the two groove walls.

[0009] By setting the pressure relief groove to extend continuously, the pressure relief space formed by the pressure relief groove is expanded, and the extrusion pressure can be continuously released along the extension direction of the heating tube; by using deformable connectors, the radial extrusion pressure on the heating plate is released through deformation, which further improves the pressure relief effect and the flatness of the heating plate; moreover, based on the continuous extension of the pressure relief groove, the connectors are used to improve the connection strength of the heating plate itself, reduce deformation, and facilitate the stamping and forming of the pressure relief groove.

[0010] More preferably, the connector includes a connecting rib that arches toward the side away from the baking pan.

[0011] The connecting ribs are arched towards the side away from the baking pan. The connecting ribs rely on their own shape to achieve elastic deformation in order to absorb the radial extrusion force of the heating pan. At the same time, the connecting ribs have a simple structure, which allows the two walls of the pressure relief groove to be reliably connected, thereby strengthening the connection strength of the heating pan itself.

[0012] More preferably, the connector is integrally formed on the heating plate;

[0013] By integrally molding the connector with the heating plate, the separate assembly process is eliminated. The connector and the heating plate are produced together, or the connector is formed on the pre-molded heating plate through processes such as cutting. This makes production more convenient, and the connector and the heating plate can have a reliable connection for reliable pressure buffering and release.

[0014] More preferably, the connector is a spring mounted on the heating plate.

[0015] By setting the connector as a spring, the squeezing force between the two slot sidewalls can be buffered, the stress on the heating plate can be distributed, and stress concentration can be avoided to prevent the heating plate from bulging.

[0016] In a preferred embodiment, the pressure relief groove is formed by the heating plate being recessed towards the side away from the baking plate.

[0017] By forming a pressure relief groove that is recessed from the heating plate to the side away from the baking plate, heat transfer loss caused by the heating plate penetrating through is avoided. The heat from the heating plate is evenly transferred when passing through the pressure relief groove, so that the pressure relief groove can not only prevent the heating plate from deforming, but also ensure reliable heat transfer at the pressure relief groove position, thereby improving the heat transfer uniformity of the heating plate.

[0018] In a preferred embodiment, the pressure relief groove includes a plurality of segments arranged at intervals conforming to the mounting groove.

[0019] By setting the pressure relief groove as multiple segments arranged at intervals, it is possible to eliminate the need to set connecting ribs separately in the pressure relief groove to ensure connection strength. On the basis of releasing the radial extrusion pressure of the heating plate from multiple directions by utilizing the pressure relief groove, the structural reliability of the heating plate can also be ensured.

[0020] In a preferred embodiment, the mounting groove extends around the center of the heating plate and forms two ends, and the pressure relief groove includes a first annular groove arranged radially inside the mounting groove, with a deformable first connector connecting the groove walls of the first annular groove.

[0021] More preferably, the pressure relief groove further includes a second annular groove arranged radially outward from the mounting groove, and a deformable second connector is connected between the groove walls of the second annular groove.

[0022] Because the heating plate, typically located in the central area inside the mounting groove, has a small area, it experiences high pressure and is prone to deformation when subjected to the extrusion force of the heating tube. Therefore, the pressure relief groove includes a first annular groove parallel to the radial inner side of the mounting groove. This reliably releases the radial pressure within the mounting groove, effectively preventing axial deformation in the center of the heating plate, improving its flatness, and enhancing the fit between the heating plate and the baking tray. Furthermore, to prevent the heating plate from being severed due to the first annular groove, a first connector ensures reliable connection and strength. Simultaneously, the deformable first connector releases the radial extrusion force on the heating plate through deformation, preventing axial deformation and bulging.

[0023] Similarly, the pressure relief groove also includes a second annular groove arranged radially outward from the mounting groove. A deformable second connector is connected between the groove walls of the second annular groove. The pressure is released radially outward from the mounting groove using the second annular groove, preventing deformation of the heating plate edge and improving the fit between the heating plate and the baking plate. Moreover, the second connector releases the radial compressive force of the heating plate through deformation, preventing the heating plate from bulging due to axial deformation.

[0024] In a preferred embodiment, the mounting groove includes a mounting arc segment extending around the center of the heating plate and a mounting straight segment connected to one end of the mounting arc segment, and the pressure relief groove includes a pressure relief arc segment parallel to the mounting arc segment and a pressure relief straight segment parallel to the mounting straight segment.

[0025] The mounting groove is equipped with an arc section and a straight section, allowing the extrusion pressure to be released in different directions, thus avoiding stress concentration on the heating plate. The pressure relief groove includes a pressure relief arc section that runs parallel to the arc section and a pressure relief straight section that runs parallel to the straight section, so that the radial extrusion pressure along different parts of the mounting groove can be reliably released and buffered, preventing the heating plate from bulging and deforming.

[0026] In a preferred embodiment, the mounting groove includes an inner arc segment and an outer arc segment located on the outer ring of the inner arc segment, and the pressure relief groove includes at least a pressure relief section arranged between the inner arc segment and the outer arc segment.

[0027] The mounting groove includes an inner arc segment and an outer arc segment, which allows for multiple rings of heating tubes on the heating plate, expanding the heating area and improving the heating efficiency of the baking plate. The pressure relief groove includes a pressure relief section arranged between the inner arc segment and the outer arc segment. In the area between the inner arc segment and the outer arc segment, the heating plate area is small. Under the condition that it is likely to be deformed due to radial extrusion, the pressure relief section releases the extrusion pressure in this area, thereby improving the flatness of the heating plate, improving the fit with the baking plate, and ensuring uniform heat transfer.

[0028] In a preferred embodiment, the heating plate protrudes to the side away from the baking pan to form the mounting groove.

[0029] Instead of creating a recessed area on the upper surface of the heating plate, the mounting groove is formed by protruding the heating plate away from the baking plate. In other words, the groove wall itself protrudes to provide deformable space. When pressing the heating tube, the groove wall itself can adapt to the deformation to buffer the radial extrusion force on the heating plate and reduce the axial deformation of the heating plate.

[0039] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] like Figure 1As shown, in one embodiment of the present invention, a grilling machine is provided, including a housing 10, a heating component 20, and a grilling pan 30. The heating component 20 is located between the housing 10 and the grilling pan 30. The heating component 20 includes a heating plate 21 and a heating tube 22. The heating plate 21 is provided with a mounting groove 23 on the side facing the grilling pan 30. The heating tube 22 is die-cast in the mounting groove 23. The heating plate 21 is also provided with a pressure relief groove 24. The pressure relief groove 24 and the mounting groove 23 are recessed in the same direction on the heating plate 21. The pressure relief groove 24 is provided on the outer ring and / or inner ring of the mounting groove 23.

[0044] Preferably, the pressure relief groove extends in the direction of the extension of the mounting groove 23. That is, when the mounting groove has a straight extension portion, the pressure relief groove can extend at least partially parallel to the straight extension of the mounting groove; when the mounting groove has an arc extension portion, the pressure relief groove can at least partially match the arc of the arc extension portion; in addition, the heating tube usually has a cold end, and the mounting groove usually has an extension end, so the pressure relief groove can continue to extend at the end of the mounting groove.

[0045] Additionally, it should be noted that the grill of this invention can be a double-sided grill, for example... Figure 1 As shown, the housing 10 includes a hinged upper housing 11 and a lower housing 12, and the baking tray 30 includes an upper baking tray 31 disposed in the upper housing 11 and a lower baking tray 32 disposed in the lower housing 12. Of course, the grill can also be a single-sided grill, in which the housing 10 includes a base and an upper cover hinged to the base, and the baking tray 30 is disposed in the base.

[0046] The grill provided by this utility model has a mounting groove 23 on the heating plate 21, and the heating tube 22 is die-cast into the mounting groove 23 to efficiently transfer heat to the heating plate 21. A pressure relief groove 24 is provided on the heating plate 21 to provide pressure relief space.

[0047] like Figure 2As shown, during the die-casting process of the heating tube by the upper die 40 and the lower die 50, the heating tube 22 generates radial extrusion force on the wall of the mounting groove 23. Since the heating plate 21 is subjected to axial force (along the Y direction) from the upper die and the lower die, the axial deformation force is transformed into radial extrusion force (along the X direction). When the extrusion force is transmitted radially along the heating plate 21 to the pressure relief groove 24, it is released in the pressure relief space within the pressure relief groove, preventing the pressure from accumulating to a level sufficient to cause damage to the internal structure of the heating plate 21 and axial deformation, thus avoiding axial deformation of the heating plate 21. In addition, since the pressure relief groove 24 is arranged side by side with the mounting groove 23 and extends in the direction of extension of the mounting groove 23, the stress of the heating plate under pressure will be distributed along the path of the pressure relief groove 24 and released in the pressure relief space of the pressure relief groove 24, reducing the high stress concentration in a single area, thereby avoiding axial deformation of the heating plate 21. Therefore, the pressure relief groove 24 allows the extrusion pressure of the heating plate 21 to be released radially, preventing the heating plate 21 from bulging due to axial deformation under pressure, thereby improving the flatness of the heating plate 21, improving the fit between the heating plate 21 and the baking tray 30, and making the heat transfer more uniform.

[0048] like Figure 1 As shown, in a preferred embodiment, the heating plate 21 protrudes to the side away from the baking plate 30 to form a mounting groove 23.

[0049] By protruding the heating plate 21 away from the baking pan 30 to form the mounting groove 23, instead of only recessing the upper surface of the heating plate 21, the groove wall of the mounting groove 23 protrudes itself to have deformable space. When pressing the heating tube 22, the groove wall of the mounting groove 23 can adaptably deform to buffer the radial extrusion force on the heating plate 21 and reduce the axial deformation of the heating plate 21.

[0050] like Figure 3 , 4 As shown, in a preferred embodiment, the pressure relief groove 23 is a through groove, the pressure relief groove 24 extends continuously following the shape of the mounting groove 23, and has two oppositely arranged groove walls, with a deformable connector 25 connecting the two groove walls.

[0051] By setting the pressure relief groove 24 to extend continuously, the pressure relief space formed by the pressure relief groove 24 is expanded, and the extrusion pressure can be continuously released along the extension direction of the heating tube 22; by using the deformable connector 25, the radial extrusion pressure on the heating plate 21 is released by the deformation of the connector 25, which further improves the pressure relief effect and improves the flatness of the heating plate 21; moreover, based on the continuous extension of the pressure relief groove 24, the connector 25 is used to improve the self-connection strength of the heating plate 21, reduce deformation, and facilitate the stamping and forming of the pressure relief groove 24.

[0052] This invention does not limit the specific form of the connector 25. For example, the connector 25 includes a connecting rib that arches away from the baking pan 30. More specifically, the form of the connector 25 can be selected as follows: Figure 3 The arc-shaped connecting rib shown; or... Figure 6 The bent connecting ribs shown;

[0053] Alternatively, the connector 25 can be a spring mounted on the heating plate 21. By setting the connector 25 as a spring, the compressive force between the two groove sidewalls can be buffered, the stress on the heating plate 21 can be distributed, and stress concentration can be avoided to prevent the heating plate 21 from bulging.

[0054] A connecting rib that arches towards the side away from the baking pan 30 is adopted. The connecting rib achieves elastic deformation by its own shape to absorb the radial extrusion force of the heating pan 21. At the same time, the connecting rib has a simple structure, which allows the two walls of the pressure relief groove 24 to be reliably connected, thereby strengthening the connection strength of the heating pan 21.

[0055] Furthermore, the connector 25 is preferably integrally formed on the heating plate 21. By integrally forming the connector 25 on the heating plate 21, the process of separate assembly is eliminated. The connector 25 and the heating plate 21 are manufactured together. Alternatively, the connector 25 can be formed on the pre-formed heating plate 21 by cutting or other processes, which makes production more convenient and ensures a reliable connection between the connector 25 and the heating plate 21 for reliable pressure buffering and release.

[0056] Of course, the pressure relief groove described above extends continuously along the mounting groove 23, preferably in a ring shape, or it can be an arc shape corresponding to the heating tube.

[0057] In another preferred embodiment, the pressure relief groove 24 is a through groove and includes multiple segments arranged at intervals following the shape of the mounting groove 23. This arrangement eliminates the need to separately install connecting ribs in the pressure relief groove 24 to ensure connection strength. While utilizing the pressure relief groove 24 to release the radial compressive force of the heating plate 21 from multiple directions, it also ensures the structural reliability of the heating plate 21.

[0058] In another preferred embodiment, the pressure relief groove is formed by the heating plate being recessed towards the side away from the baking plate.

[0059] By recessing the pressure relief groove from the heating plate to the side away from the baking plate, heat transfer loss caused by the heating plate passing through is avoided. The heat from the heating plate is evenly transferred when passing through the pressure relief groove, so that the pressure relief groove can not only prevent the heating plate from deforming, but also ensure reliable heat transfer at the pressure relief groove position, thus improving the heat transfer uniformity of the heating plate.

[0060] It should also be noted that this utility model does not limit the extension path or the number of pressure relief grooves 24. They can be rationally arranged according to the position of the mounting grooves 23 on the heating plate 21 and the reserved space, for example:

[0061] Implementation Example 1, such as Figure 1-4 As shown, the mounting groove 23 extends around the center of the heating plate 21 and forms two ends. The pressure relief groove 24 includes a first annular groove 241 arranged in parallel on the radially inner side of the mounting groove 23. A deformable first connector 25 is connected between the groove walls of the first annular groove 241.

[0062] Alternatively, the pressure relief groove 24 may further include a second annular groove 242 arranged radially outward from the mounting groove 23, wherein a deformable second connector 25 is connected between the groove walls of the second annular groove 242.

[0063] Since the heating plate 21 is located in the central area inside the mounting groove 23 and has a small area, it experiences high pressure and is prone to deformation when subjected to the extrusion force of the heating tube 22. Therefore, the pressure relief groove 24 includes a first annular groove parallel to the radial inner side of the mounting groove 23. This reliably releases the radial pressure on the radial inner side of the mounting groove 23, effectively preventing axial deformation in the middle of the heating plate 21, improving the flatness of the middle of the heating plate 21, and enhancing the fit between the heating plate 21 and the baking tray 30. Furthermore, to prevent the heating plate 21 from being cut due to the first annular groove, the first connector 25 ensures the connection reliability of the heating plate 21 and guarantees its connection strength. Simultaneously, the deformable first connector 25 can release the radial extrusion force of the heating plate 21 through deformation, preventing the heating plate 21 from bulging due to axial deformation.

[0064] Similarly, the pressure relief groove 24 also includes a second annular groove arranged radially outside the mounting groove 23. A deformable second connector 25 is connected between the groove walls of the second annular groove. The pressure is released radially around the outer periphery of the mounting groove 23 by utilizing the second annular groove, which prevents deformation of the edge of the heating plate 21 and improves the fit between the heating plate 21 and the baking plate 30. Moreover, the second connector 25 releases the radial compressive force of the heating plate 21 by deformation, preventing the heating plate 21 from bulging due to axial deformation.

[0065] In Implementation Example 2, the mounting groove 23 includes an inner arc segment 231 and an outer arc segment 232 located on the outer ring of the inner arc segment, and the pressure relief groove 24 includes at least a pressure relief section arranged between the inner arc segment and the outer arc segment.

[0066] In Example 3, the mounting groove 23 includes a mounting arc extending around the center of the heating plate 21 and a mounting straight section connected to one end of the mounting arc. Optionally, the mounting straight section extends toward or passes through the center point of the heating plate 21, so that the mounting groove is similar to an "e" shape. The pressure relief groove 24 includes a pressure relief arc parallel to the mounting arc and a pressure relief straight section parallel to the mounting straight section.

[0067] The mounting groove 23 is provided with an mounting arc segment and a mounting straight segment, so that the extrusion pressure can be released in different directions to avoid stress concentration on the heating plate 21. The pressure relief groove 24 includes a pressure relief arc segment that is parallel to the mounting arc segment and a pressure relief straight segment that is parallel to the mounting straight segment, so that the radial extrusion pressure along different parts of the mounting groove 23 can be reliably released and buffered to prevent the heating plate 21 from bulging and deforming.

[0068] The mounting groove 23 includes an inner arc segment and an outer arc segment, which can realize the multi-ring arrangement of the heating tube 22 on the heating plate 21, expand the heating area, and improve the heating efficiency of the baking plate 30. The pressure relief groove 24 includes a pressure relief section arranged between the inner arc segment and the outer arc segment. In the area between the inner arc segment and the outer arc segment, the heating plate 21 has a small area. When it is subjected to radial extrusion force, the extrusion force in this area is likely to be deformed. The pressure relief section releases the extrusion force in this area, which improves the flatness of the heating plate 21, improves the fit with the baking plate 30, and makes the heat transfer more uniform.
