[0044] The present invention provides a grilling machine 100.

[0045] With reference to Figure 1 and Figure 2 , in an embodiment of the present invention, the grilling machine 100 includes:

[0046] A base assembly 10, the base assembly 10 includes a base body 11 and a baking tray 13, and the baking tray 13 is rotatably arranged on the base body 11; and

[0047] An upper cover assembly 30, the upper cover assembly 30 includes a cover body 31, the cover body 31 is connected to the base body 11 and can be opened or closed over the baking tray 13. The cover body 31 is provided with an air inlet hole 3131 and an air outlet hole 3133, and a heat dissipation air duct 310 is formed by connecting the air inlet hole 3131 and the air outlet hole 3133. The heat dissipation air duct 310 is located inside the cover body 31.

[0048] In this embodiment, the shapes of the base assembly 10 and the upper cover assembly 30 can be generally set to be cubic. The materials of the cover body 31 and the base body 11 can be plastic materials with high structural strength and good heat dissipation. A cavity 11a is concavely formed in the base body 11, and the baking tray 13 is arranged in the cavity 11a. When the cover body 31 is closed on the base body 11, the baking tray 13 rotates in the cavity 11a and does not interfere with the cover body 31. The cover body 31 and the base body 11 can be fixed by hinge, so that the cover body 31 can be flipped relative to the base body 11 to cover or open the opening of the cavity 11a.

[0049] An upper heating element 331 can be arranged inside the cover body 31, and a lower heating element (not labeled) can be arranged inside the base body 11. The lower heating element is located at the bottom of the cavity 11a. Thus, during the process of heating food, the upper heating element 331 and the lower heating element can be used to heat both sides of the food simultaneously to improve the heating efficiency.

[0050] The shapes and sizes of the air inlet holes 3131 and the air outlet holes 3133 may be the same or different. For example, the shapes of the air inlet holes 3131 and the air outlet holes 3133 may both be circular or square, etc. The positions of the air inlet holes 3131 and the air outlet holes 3133 may be set on the top wall of the cover body 31 or on the side wall of the cover body 31.

[0051] It can be understood that the position of the upper heating element 331 located within the cover body 31 should be outside the heat dissipation air duct 310, so that most of the heat generated by the upper heating element 331 can be transmitted towards the baking tray 13, and when a small part of the heat is transmitted to the surface of the cover body 31, it needs to cross the heat dissipation air duct 310.

[0052] Therefore, for the grilling machine 100 of the technical solution of the present invention, by connecting the base body 11 of the base assembly 10 with the cover body 31 of the upper cover assembly 30, the cover body 31 can be opened or closed on the baking tray 13, so that the food can be taken and placed or cooked and heated. By rotatably arranging the baking tray 13 on the base body 11, that is, the baking tray 13 can rotate relative to the cover body 31 and the base body 11. In this way, during the process of heating the food, the food in the baking tray 13 can rotate relative to the heat source, so that the food is heated evenly, effectively avoiding the phenomenon of the food being scorched.

[0053] In addition, in the technical solution of the present application, by providing the air inlet holes 3131 and the air outlet holes 3133 on the cover body 31, the air inlet holes 3131 and the air outlet holes 3133 are communicated to form the heat dissipation air duct 310, and the heat dissipation air duct 310 is located within the cover body 31. Thus, when the heat of the heat source for heating the food attempts to dissipate towards the surface and the outside of the cover body 31, it can be carried away by the air in the heat dissipation air duct 310, effectively avoiding the cover body 31 from generating high temperature and heat, and further preventing the phenomenon of scalding the user.

[0054] With reference to Figures 3 to 6 In order to realize the rotation of the baking tray 13, in an embodiment of the present application, the base assembly 10 includes a rotating member 15, the rotating member 15 is arranged within the base body 11, a positioning member 131 is provided on one side of the baking tray 13 facing the base body 11, and when the rotating member 15 is driven, it can abut against and drive the positioning member 131 to make the baking tray 13 rotate relative to the base body 11.

[0055] In this embodiment, the rotating member 15 includes a connecting column 151 and an abutting block 153. One end of the connecting column 151 is connected to the output end of the driving member 17, and the other end is connected to the abutting block 153. The abutting block 153 is arranged at an angle with the connecting column 151, and the abutting block 153 abuts against the positioning member 131. The positioning member 131 is located on the side of the baking tray 13 facing the bottom wall of the cavity 11a, and forms an integral structure with the bottom wall of the baking tray 13 to ensure good structural strength between the positioning member 131 and the baking tray 13. The driving member 17 and the rotating member 15 are arranged at the bottom of the cavity 11a. The connecting column 151 is connected to the driving member 17 and extends toward the baking tray 13. Therefore, when the driving member 17 drives the connecting column 151 to rotate, the connecting column 151 drives the abutting block 153 to abut against the positioning member 131, thereby driving the baking tray 13 arranged in the cavity 11a to rotate. It can be understood that in this embodiment, the transmission is only achieved through the abutment between the positioning member 131 and the rotating member 15, so that there is no need to set a more complicated structure on the baking tray 13, which is beneficial to simplify the structure of the baking tray 13 and ensure the strength of the baking tray 13 itself.

[0056] Furthermore, if Figure 5 and Figure 6 As shown, in the direction in which the baking tray 13 rotates relative to the seat body 11 , there is a gap between the rotating member 15 and the positioning member 131 , and the rotating member 15 can rotate in the gap.

[0057] Specifically, the gap is formed between the abutment block 153 of the rotating member 15 and the positioning member 131, and the size of the gap can be adaptively set according to actual conditions. By setting a gap between the rotating member 15 and the positioning member 131, when more and heavier food materials are placed on the baking tray 13, the driving member 17 has a buffer movement space due to the gap between the rotating member 15 and the baking tray 13 when starting, and can abut and drive the baking tray 13 carrying larger food materials through the rotating member 15 after starting to work normally. In this way, the possibility of the driving member 17 being stuck and heated due to the greater resistance caused by the large amount of food materials placed on the baking tray 13 when starting is reduced, thereby ensuring the normal and stable operation of the cooking appliance.

[0058] In one embodiment of the present application, there are multiple abutment blocks 153, which are spaced apart around the center line of the connecting column 151; there are multiple positioning members 131, which are spaced apart around the center line of the baking tray 13, and an abutment block 153 is provided between each two adjacent positioning members 131, and the gap is formed between each abutment block 153 and the positioning member 131 adjacent to the abutment block 153.

[0059] It can be understood that the arrangement of the plurality of abutting blocks 153 and the plurality of positioning members 131 enables each part of the baking tray 13 to be driven in the circumferential direction of rotation through the abutting cooperation of the plurality of abutting blocks 153 and the plurality of positioning members 131, thereby facilitating the quick and relatively stable driving of the baking tray 13 by the rotating member 15. Moreover, such an arrangement also facilitates ensuring that the rotating member 15 can abut and drive the positioning member 131 when being driven, which is conducive to ensuring the effectiveness of the driving of the baking tray 13 by the rotating member 15. At the same time, the overall strength of the rotating member 15 is improved, and the possibility of its fracture during the abutting and driving of the positioning member 131 is reduced, which is conducive to extending the service life of the rotating member 15. In addition, the driving member 17 for driving the rotating member 15 to rotate can be a bidirectional synchronous motor, so that when the abutting block 153 of the rotating member 15 is resisted by one of the two adjacent positioning members 131 during rotation in one direction, it can rotate in the opposite direction. Thus, when the baking tray 13 is installed in the cavity 11a, it is only necessary to ensure that one abutting block 153 is inserted into the two positioning members 131, and there is no need to adjust the placement angle of the baking tray 13 circumferentially. Of course, the driving member 17 can also be a unidirectional motor. In this case, when the baking tray 13 is installed in the cavity 11a, after one abutting block 153 is inserted into the two positioning members 131, the baking tray 13 is rotated in the opposite direction of the rotation direction of the driving member 17 until the abutting block 153 abuts against one of the two positioning members 131, which can ensure that when the driving member 17 is started, the abutting block 153 can rotate between the two positioning members 131 to ensure the normal start of the driving member 17.

[0060] Referring to Figure 6 , based on the above embodiments, in the present application, the rotation angle α formed by the rotation of the abutting block 153 between two adjacent positioning members 131 is not less than 5° and not more than 80°.

[0061] When α is less than 5°, the rotation gap between the abutting block 153 between the two positioning members 131 is small, which will affect the movement buffering effect of the driving member 17 when starting. When the rotation angle α formed by the rotation of the abutting block 153 between two adjacent positioning members 131 is greater than 80°, the rotation gap between the abutting block 153 between the two positioning members 131 is large, which will cause the abutting block 153 to abut and drive the positioning member 131 only after rotating for a long time, thus affecting the driving efficiency of the baking tray 13. Therefore, in order to balance the movement buffering effect of the driving member 17 and the driving efficiency of the baking tray 13, the rotation angle α formed by the rotation of the abutting block 153 between two adjacent positioning members 131 is set to 5° ≤ α ≤ 80°. Among them, the rotation angle α formed by the rotation of the abutting block 153 between two adjacent positioning members 131 can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, and of course, it can also be any value within the above range.

[0062] Continue to refer to Figure 3 Furthermore, in an embodiment of the present application, a spacing is formed between the surface of the abutting block 153 facing away from the connecting column 151 and the surface of the baking tray 13 provided with the positioning member 131.

[0063] Specifically, a support structure may be provided between the bottom wall or the side wall of the baking tray 13 and the base body 11, and the support structure abuts and supports the baking tray 13, so that a spacing is formed between the surface of the abutting block 153 facing away from the connecting column 151 and the surface of the baking tray 13 provided with the positioning member 131. With such a setting, the rotating member 15 is not affected by the pressing force of the baking tray 13 and is only subjected to the circumferential resistance of the positioning member 131 during driving. In this way, the magnitude of the resistance suffered by the driving member 17 when driving the rotating member 15 to rotate is reduced, thereby further reducing the possibility of the driving member 17 being stuck due to excessive force when starting. At the same time, such a setting also reduces the possibility of the baking tray 13 transferring heat to the driving member 17 through the rotating member 15 after being heated, which is beneficial to improving the protection effect of the driving member 17.

[0064] Refer to Figure 3 and Figure 4 Furthermore, in an embodiment of the present application, the base assembly 10 further includes a plurality of rolling members 19, and the plurality of rolling members 19 are arranged at intervals along the circumferential direction of the base body 11. The baking tray 13 abuts against the plurality of rolling members 19 and can be driven by the rotating member 15 to rotate.

[0065] Among them, the rolling members 19 can be rollers, balls, etc. A plurality of rolling members 19 can be embedded and fixed on the surface of the seat body 11 formed with a cavity 11a, and the number of rolling members 19 can be 3, 4 or more. By providing the rolling members 19, during the process of the baking tray 13 being driven by the rotating member 15 to rotate, the baking tray 13 and the seat body 11 are in rolling friction, so that the frictional force received by the baking tray 13 when rotating relative to the seat body 11 can be reduced, which is beneficial to improving the smoothness of the rotation of the baking tray 13. At the same time, wear is reduced during the rotation process, which is beneficial to extending the service life of the baking tray 13 and the support structure. Moreover, by providing the rolling members 19, the noise caused by the mutual friction between the baking tray 13 and the seat body 11 can be greatly reduced.

[0066] The above content mainly introduces the related embodiments of the relative rotation of the baking tray 13. Next, the related content of the heat dissipation air duct 310 in the cover body 31 will be specifically introduced.

[0067] Please refer to Figure 2 and Figure 7 In an embodiment of the present application, the grilling machine 100 further includes an exhaust device 35. The exhaust device 35 is disposed in the heat dissipation air duct 310 and can drive air to enter through the air inlet hole 3131 and discharge through the air outlet hole 3133. Among them, the exhaust device 35 can be a fan, a blower or an induced draft fan, etc. The exhaust device 35 can be disposed near the air inlet hole 3131 or near the air outlet hole 3133. In order to stably install the exhaust device 35, the exhaust device 35 can be installed on the inner wall of the cover body 31 by using a bracket. By providing the exhaust device 35, the air flow rate in the heat dissipation air duct 310 can be increased, so that the heat transferred to the surface of the cover body 31 can be quickly taken away.

[0068] Further, referring to Figure 9 One side edge of the cover body 31 extends outward to form a handle 3111. The air inlet hole 3131 and the air outlet hole 3133 are symmetrically disposed on the side of the cover body 31 away from the handle 3111. Specifically, the handle 3111 can be formed by extending the edge of the cover body 31. Through the handle 3111, the opening and closing operations of the upper cover assembly 30 can be easily realized. By disposing the air inlet hole 3131 and the air outlet hole 3133 away from the handle 3111, when the user operates the handle 3111, the user will not be scalded by the hot air discharged from the heat dissipation air duct 310.

[0069] In the embodiments of the present application, the number of the air inlet holes 3131 is multiple, and the multiple air inlet holes 3131 are arranged on the cover body 31 to form a hole array; and / or, the number of the air outlet holes 3133 is multiple, and the multiple air outlet holes 3133 are arranged on the cover body 31 to form a hole array. In this embodiment, both the air inlet holes 3131 and the air outlet holes 3133 are micropores, and the multiple air inlet holes 3131 and the multiple air outlet holes 3133 both form a hole array on the cover body 31. The shape of the hole array can be circular or square. In this way, a grille structure is formed on the cover body 31, which can not only increase the air intake and air output of the heat dissipation air duct 310, but also prevent foreign objects from entering the cover body 31 through the air inlet holes 3131 or the air outlet holes 3133, thereby effectively preventing the heat dissipation air duct 310 from being blocked.

[0070] Further, in the present application, the height of the orifice of the air inlet hole 3131 located inside the cover body 31 in the vertical direction is higher than the height of the orifice at the other end in the vertical direction; and / or, the height of the orifice of the air outlet hole 3133 located inside the cover body 31 in the vertical direction is higher than the height of the orifice at the other end in the vertical direction. With such a setting, the liquid adhering to the outer side wall of the cover body 31 cannot enter the cover body 31 through the air inlet hole 3131 or the air outlet hole 3133, thereby greatly improving the waterproof performance of the griddle 100 and avoiding safety risks caused by water ingress.

[0071] Referring to Figure 8 , based on the above embodiments, the included angle between the center line of the air inlet hole 3131 or the air outlet hole 3133 and the horizontal line is β, satisfying the relationship: 5° ≤ β ≤ 45°.

[0072] The included angle β should not be too large or too small. If it is too large, the inclination angle of the air inlet hole 3131 or the air outlet hole 3133 is too large, so that when the air in the cover body 31 is discharged through the air outlet hole 3133, or when the fresh air outside enters through the air inlet hole 3131, the corner of the air flow path is too large, which is not conducive to the smooth flow of air; if it is too small, the heights of the orifices at both ends of the air inlet hole 3131 or the air outlet hole 3133 will be relatively close, and the air inlet hole 3131 or the air outlet hole 3133 tends to be flat, resulting in external water or oil liquid, etc. being easily introduced into the cover body 31 through the air inlet hole 3131 or the air outlet hole 3133, increasing the risk of water ingress. Therefore, in this embodiment, the included angle β is set within the range of not less than 5° and not greater than 45°.

[0073] It can be understood that in practical applications, the included angle β between the center line of the air inlet hole 3131 or the air outlet hole 3133 and the horizontal line can specifically be 5°, 10°, 15°, 20°, 30°, 35°, 40° or 45°.

[0074] Combined with reference toFigure 2 , Figure 7 and Figure 10 In one embodiment of the present application, the upper heating element 331 is a light wave tube, which can be annular or quasi-annular, and the center of the light wave tube coincides with the center of the cover 31. It can be understood that by setting the upper heating element 331 as a light wave tube, the light wave heat source provided by the light wave tube can quickly generate high temperature and high heat, and the cooling speed is also faster, the heating efficiency is higher, and the food will not be burnt, thereby ensuring the color and taste of the food. Of course, in other embodiments, the upper heating element 331 can also be a heating device such as an electric heating tube or an electric heating wire.

[0075] Please continue to refer to Figure 2 In order to allow most of the heat of the upper heating element 331 to be transferred to the baking tray 13 for heating, in one embodiment of the present application, the upper cover assembly 30 also includes a reflective cover 333, which is connected to the cover body 31 and encloses the heat dissipation duct 310, and the upper heating element 331 is located on the side of the reflective cover 333 away from the heat dissipation duct 310.

[0076] In this embodiment, the cover body 31 protects the top cover plate 311 connected to the side panels 313 of the top cover plate 311, the side panels 313 are provided with the air inlet holes 3131 and the air outlet holes 3133, and the reflector 333 is connected to the inner wall of the side panels 313. The reflector 333 can be a circular cover structure, and the reflector 333 can reflect the heat of the upper heating element 331, and reflect the heat emitted outward to the grilling plate 13 of the grilling machine 100. Therefore, when the heat of the upper heating element 331 tries to be transferred outward to the outside or surface of the cover body 31, most of it can be reflected back by the reflector 333, and a small part of the heat that passes through can also be taken away by the airflow in the heat dissipation duct 310, thereby improving the heat utilization rate and avoiding the formation of high temperature and heat on the surface of the cover body 31.

[0077] Furthermore, the upper cover assembly 30 further includes a heat insulation cover 335, which is connected to the side of the reflector cover 333 away from the upper heating element 331, and is enclosed with the reflector cover 333 and the cover body 31 to form the heat dissipation duct 310. The heat insulation cover 335 can also be a circular cover structure, and its diameter is smaller than the diameter of the reflector cover 333. The heat insulation cover 335 cover is connected to the outer wall of the reflector cover 333, and is enclosed with the reflector cover 333 and the cover body 31 to form the above-mentioned heat dissipation duct 310. It can be understood that by setting the heat insulation cover 335, the heat that passes through the reflector cover 333 can be blocked, so that the dissipated heat can avoid being blocked and ventilated and dissipated by the reflector cover 333, the heat insulation cover 335 and the heat dissipation duct 310 in sequence, forming a triple protection to ensure that the cover body 31 does not generate high temperature.

[0078] Further, the upper cover assembly 30 further includes a protective cover 337. The protective cover 337 is connected to the reflector 333 and encloses to form an installation cavity 339, and the upper heating element 331 is located in the installation cavity 339.

[0079] Specifically, the protective cover 337 can be a microporous plate structure with multiple micropores, which can allow heat to pass through. The protective cover 337 can be detachably fixed to the inner wall of the reflector 333 by means of snap connection, buckle connection, etc. Thus, through the arrangement of the protective cover 337, while the heat of the upper heating element 331 in the installation cavity 339 can be normally transferred, it can also prevent users from accidentally touching the upper heating element 331.

[0080] Please refer to again Figure 2 , in another embodiment of the present application, a buffer space 310a is formed between the side walls of the reflector 333 and the heat insulation cover 335 and the side enclosure plate 313 of the cover body 31, and a wind passing space 310b is formed between the top walls of the reflector 333 and the heat insulation cover 335 and the top cover plate 311 of the cover body 31. The buffer space 310a and the wind passing space 310b communicate with each other and form the heat dissipation air duct 310.

[0081] Specifically, in this embodiment, a ring or a half-ring of buffer space 310a is formed between the side walls of the reflector 333 and the heat insulation cover 335 and the side enclosure plate 313, and the top is the wind passing space 310b. Therefore, in actual situations, after the air enters through the air inlet hole 3131 on one side of the side enclosure plate 313, it first reaches the buffer space 310a, blows head-on against the side walls of the reflector 333 and the heat insulation cover 335, and then rises to a certain height and then passes through the wind passing space 310b in a laminar flow, and then descends to the buffer space 310a on the other side and is discharged through the corresponding air outlet hole 3133. With such an arrangement, the heat dissipation air duct 310 forms a circuitous path in the cover body 31, so that the area of contact between the air and the reflector 333 and the heat insulation cover 335 is larger and the residence time in the cover body 31 is longer, which is more conducive to discharging the heat in the cover body 31 and preventing the cover body 31 from generating high temperature.

[0082] Further, in an embodiment of the grilling machine 100 of the present application, the grilling machine 100 further includes a buffer structure, which is provided at least at one of the base 11 and the upper cover assembly 30, and can be used to provide a buffering force when the upper cover assembly 30 opens or closes the baking tray 13. That is, the buffer structure can be provided alone on the upper cover assembly 30 or the base 11, or part of it can be provided on the upper cover assembly 30 and the other part on the base 11. It should be noted that the buffering force provided by the buffer structure can buffer the impact force when the two are closed, or can buffer the impact force after opening to a preset angle when the upper cover assembly 30 and the base 11 are opened.

[0083] In this embodiment, through the design of the buffer structure, a buffering force is provided during the opening or closing process of the upper cover assembly 30 and the base 11 to buffer the impact force during opening or closing. Therefore, even when the upper cover assembly 30 is heavy, no strong impact will occur during the state change of opening or closing with the base 11, effectively avoiding damage to the upper cover assembly 30 and the base 11 during opening or closing, and avoiding safety accidents such as pinching hands.

[0084] Please refer to Figures 10 to 14 , in an embodiment of the present application, the buffer structure is a damper 50. The upper cover assembly 30 includes a hinge shaft 36 fixedly connected to the cover body 31. The damper 50 is sleeved outside the hinge shaft 36 and connected to the base 11, so that the cover body 31 can be turned relative to the base 11 to open or close the base assembly 10.

[0085] In this embodiment, refer to Figure 13, the damper 50 can be a hydraulic damper, which includes a sleeve 51 and a core 53 disposed within the sleeve 51. An outer wall of the sleeve 51 extends to form a mounting portion 511, and is fixedly connected to the base assembly 10 through the mounting portion 511. The hinge shaft 36 passes through the core 53 inside the sleeve 51. A partition 55 is provided on the core 53. The partition 55 divides the space inside the sleeve 51 into two parts, and the partition 55 is provided with a liquid passing hole 551 communicating the two parts of the space. Hydraulic oil is present in both of these two parts of the space. Therefore, when the cover body 31 rotates relative to the base assembly 10, the hinge shaft 36 rotates together with the cover body 31. At this time, the hinge shaft 36 drives the core 53 and the partition 55 on the core 53 to rotate together. Thus, during the rotation process of the partition 55, while squeezing the hydraulic oil, the hydraulic oil also acts on the partition 55 with a reaction force, thereby forming a buffering effect. Of course, in another embodiment, the damper 50 can also be a structure such as an elastic damper that is commonly used in the prior art. Using the damper 50 as a buffering structure can buffer the impact of the relatively heavy upper cover assembly 30 and has strong reliability.

[0086] In order to keep the hinge shaft 36 relatively fixed to the cover body 31, in the present application, the upper cover assembly 30 further includes a fixing member 34. The cover body 31 is provided with a mounting seat 315. The fixing member 34 is fixedly connected to the mounting seat 315, and the hinge shaft 36 is inserted and fixed to the fixing member 34. Specifically, the number of the mounting seat 315 and the fixing member 34 is two respectively. Two ends of the hinge shaft 36 are respectively inserted and fixed to the fixing member 34 and fixed to the mounting seat 315 through the fixing member 34. In this way, not only is the hinge shaft 36 stably installed, but also the operations of assembly and disassembly are relatively convenient.

[0087] Based on the above embodiment of the fixing member 34, in the present application, the fixing member 34 includes a cylindrical body portion 341 and a positioning portion 343 provided on an outer side wall of the cylindrical body portion 341. The hinge shaft 36 is inserted and fixed to the cylindrical body portion 341. The mounting seat 315 is provided with a limiting hole 3151, and a limiting groove 3153 is recessed in a hole wall of the limiting hole 3151. The cylindrical body portion 341 is installed in the limiting hole 3151, and the positioning portion 343 is clamped in the limiting groove 3153.

[0088] In this embodiment, the cylinder part 341 and the positioning part 343 are of an integral structure. The number of the positioning parts 343 can be multiple, and the multiple positioning parts 343 are arranged at intervals along the circumferential direction of the cylinder part 341. The number of the limiting grooves 3153 corresponds to that of the positioning parts 343. In practical applications, when the cylinder part 341 is inserted into the limiting hole 3151, the positioning part 343 and the limiting groove 3153 are matched simultaneously, so as to limit the circumferential direction of the cylinder part 341 and prevent the cylinder part 341 from rotating in the limiting hole 3151. Thus, after the hinge shaft 36 is inserted into the cylinder part 341, it can be ensured that the hinge shaft 36 and the cover body 31 will not rotate relative to each other.

[0089] With reference to Figure 12 , in order to enable the hinge shaft 36 and the cylinder part 341 to be firmly inserted and fixed, in an embodiment of the present application, a first anti-rotation plane 361 is provided on the outer wall of the hinge shaft 36, and a second anti-rotation plane 3411 that fits with the first anti-rotation plane 361 is provided on the inner wall of the cylinder part 341. Specifically, the end of the hinge shaft 36 can first pass through the mounting seat 315 and then extend into the limiting hole 3151, and is in interference fit with the cylinder part 341 in the limiting hole 3151 to achieve fixation. At the same time, the first anti-rotation plane 361 on the hinge shaft 36 and the second anti-rotation plane 3411 on the inner wall of the cylinder part 341 are in mutual fit, so as to form a circumferential limit for the hinge shaft 36 and improve the stability of the installation of the hinge shaft 36.

[0090] Based on the above embodiments of the damper 50, considering that in some cases the weight of the upper cover assembly 30 is relatively heavy, and there will still be a large impact force after buffering by the damper 50 during the covering process, which is likely to generate a large pressure on the food on the baking tray 13 and affect the shape and taste of the food. Therefore, in an embodiment of the present application, the upper cover assembly 30 further includes an elastic member 37, one end of the elastic member 37 is connected to the cover body 31, and the other end is connected to the base assembly 10; when the elastic member 37 is in a natural state, the cover body 31 opens the base assembly 10; when the cover body 31 covers the base assembly 10, the elastic member 37 has an elastic force on the cover body 31 in the direction of opening the base assembly 10.

[0091] One end of the elastic member 37 is connected to the upper cover body 31, and the other end is connected to the base assembly 10, so that when the upper cover assembly 30 covers towards the base assembly 10, the elastic member 37 has an elastic force on the upper cover assembly 30 in the direction away from the upper cover assembly 30 and towards the base assembly 10. Thus, this elastic force can balance a part of the gravity of the upper cover assembly 30, and further reduce the pressure of the upper cover assembly 30 on the food placed on the baking tray 13, so as to better ensure the original shape and good taste of the food.

[0092] Specifically, the elastic member 37 can be a spring or a spring. When the elastic member 37 is a spring, the spring can be a telescopic spring or a torsion spring. For example, when the elastic member 37 is a telescopic spring, one end of the telescopic spring can be connected to the side of the cover 31 facing the base assembly 10, and the other end can be connected to the side of the base assembly 10 facing the cover 31. When the cover 31 is in a state of opening the base assembly 10, the spring is compressed; when the cover 31 changes from the above-mentioned equilibrium state to the state of covering the base assembly 10, the spring is further compressed, and the elastic force of the spring on the cover 31 increases at this time. When the cover 31 completely covers the base assembly 10, the pressure of the cover 31 on the food is less than its own gravity. Of course, in the technical solution of the present invention, the elastic member 37 can also be set on the side of the cover 31 away from the base assembly 10, as long as the elastic member 37 has an elastic force on the cover 31 in the direction of opening the base assembly 10 after the cover 31 covers the base assembly 10.

[0093] In one embodiment of the present application, the elastic member 37 is a torsion spring, and the torsion spring is sleeved outside the hinge shaft 36. In practical applications, the two connecting ends of the torsion spring are respectively connected to the cover body 31 and the base assembly 10. Since the torsion spring has a torsional moment, it can be pulled in the opposite direction when the cover body 31 is closed. In addition, the torsion spring has good anti-fatigue performance and is more reliable than other elastic members 37 under dynamic load.

[0094] Based on the above embodiment, in order to prevent the torsion spring from being worn with the hinge shaft 36 during movement after being sleeved on the hinge shaft 36, the upper cover assembly 30 described in the present application further includes a protective sleeve 38, the protective sleeve 38 is sleeved on the outer wall of the hinge shaft 36, and the torsion spring is sleeved outside the protective sleeve 38. Specifically, the protective sleeve 38 can be a plastic sleeve or a metal sleeve with strong wear resistance and good fatigue resistance. The protective sleeve 38 is relatively fixed to the hinge shaft 36, and blocks the torsion spring from directly contacting the hinge shaft 36 to form a protective effect.

[0095] In some other embodiments of the grilling machine 100 of the present application, the buffer structure includes a first magnetic member (not shown) and a second magnetic member (not shown), the first magnetic member is arranged on the side where the base assembly 10 and the upper cover assembly 30 overlap, the second magnetic member is arranged on the side where the upper cover assembly 30 and the base assembly 10 overlap corresponding to the first magnetic member, and the first magnetic member and the second magnetic member magnetically repel each other.

[0096] The first magnetic member and the second magnetic member can be permanent magnets or electromagnets, and their magnetisms repel each other. The first magnetic member can be embedded and fixed on one side of the base assembly 10 facing the upper cover assembly 30, and the second can be embedded and fixed on one side of the upper cover assembly 30 facing the base assembly 10, and their positions correspond to each other. Thus, when the upper cover assembly 30 covers the base assembly 10, the repulsive force between the first magnetic member and the second magnetic member can buffer the relatively heavy upper cover assembly 30, preventing potential safety hazards caused by strong impacts on the upper cover assembly 30.

[0097] Further, the first magnetic member is arranged at a position on the base assembly 10 away from the hinge with the upper cover assembly 30. That is, the positions of the first magnetic member and the second magnetic member are on the side away from the hinge axis 36. Understandably, such an arrangement enables the repulsive force between the first magnetic member and the second magnetic member to better counteract the relatively heavy upper cover assembly 30 and is more in line with the design of mechanical principles.

[0098] Please refer to Figure 15 , in an embodiment of the present application, the griddle 100 further includes a baffle 70. The baffle 70 is connected to the base assembly 10 and shields the hinged part between the base assembly 10 and the upper cover assembly 30. Among them, the baffle 70 can be detachably fixed to the seat body 11 of the base assembly 10 by means of screw connection, snap connection, etc., and forms a shield for the hinged part. In this way, through the design of the baffle 70, not only the overall appearance of the griddle 100 is more beautiful, but also it can prevent users from accidentally touching the hinged part between the upper cover assembly 30 and the base assembly 10 and causing safety risks such as pinching hands.

[0099] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
