Description

Technical Field

[0001] The present invention relates to the technical field of cooking equipment, and in particular to a frying and grilling machine. Background Art

[0002] Grilling machines in the related art all use a fixed heating structure. For example, a fixed heating tube or heating wire is installed to heat the grilling pan, thereby heating the pan and cooking the food. However, grilling machines in the related art have the following problems: the grilling pan and the heating element are relatively fixed in position, and the heating area of ​​the grilling pan causes uneven heating of the pan. The heated area becomes increasingly hot, and there is a temperature difference with the non-heated area. This results in poor cooking effect, and the food is often partially undercooked or overheated, which affects cooking efficiency. Summary of the Invention

[0003] The main purpose of the present invention is to provide a frying and grilling machine, which aims to achieve uniform heating of food and reduce the occurrence of burning, thereby improving the cooking effect of the frying and grilling machine on food.

[0022] Alternatively, the transmission structure includes a driving wheel, a driven wheel and a conveyor belt, the driving wheel is connected to the driving member, the driven wheel is connected to the connecting column, and the conveyor belt is sleeved on the driving wheel and the driven wheel.

[0023] In one embodiment of the present invention, a heat dissipation channel is formed in the upper cover, and the light wave tube is located outside the heat dissipation channel.

[0024] In one embodiment of the present invention, the upper cover assembly further comprises an upper reflector, which is connected to the upper cover and is located on a side of the upper cover facing the baking tray;

[0025] The upper reflector and the upper cover enclose the heat dissipation channel, and the light wave tube is located on a side of the upper reflector away from the heat dissipation channel.

[0026] In one embodiment of the present invention, the upper cover assembly further includes a heat shield, which is connected to the upper reflector and located on a side of the upper reflector facing away from the light wave tube.

[0027] And / or, the upper cover assembly further includes a protective cover, the protective cover is connected to the upper reflective cover and encloses a placement cavity, and the light wave tube is located in the placement cavity.

[0028] In one embodiment of the present invention, the upper cover is further provided with an air inlet and an air outlet, and the air inlet and the air outlet are both connected to the heat dissipation channel;

[0029] The vertical height of the opening of the air inlet and / or the air outlet located in the upper cover is higher than the vertical height of the opening at the other end.

[0030] In one embodiment of the present invention, the upper cover assembly further comprises a multi-layer window structure, which is provided on the upper cover and encloses the upper cover to form a light-transmitting and heat-insulating cavity, wherein the light-transmitting and heat-insulating cavity and the heat dissipation channel are spaced apart.

[0036] The grilling machine of the present invention rotatably mounts the grilling tray of the base assembly on the base. This allows the grilling tray to rotate relative to the base during cooking, causing the food within the grilling tray to rotate relative to the light wave tube of the upper cover assembly. This ensures more uniform heating of the food within the grilling tray, reducing the risk of burning, thereby improving the cooking effect of the grilling machine. Compared to the heating area of ​​a fixed heating grilling tray, the food on the grilling tray of the present invention is evenly heated, improving both cooking quality and efficiency.

[0037] Furthermore, the grilling machine of this embodiment uses a light wave tube in the upper cover assembly to provide a light wave heat source to heat the food in the grilling pan. This allows for rapid generation of high heat during the cooking process, improving heating efficiency, reducing the risk of burning, and helping to preserve the color of the food, thereby further enhancing the cooking effect of the grilling machine.

[0077] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0078] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0079] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0080] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0081] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0082] The grilling machine in the related art has the following problems: the heating element heats the grilling plate at a fixed position, and the grilling plate is heated unevenly. The heated area becomes increasingly hot, and there is a temperature difference with the area not directly heated, resulting in poor cooking effect of food. The situation of partially undercooked and partially overheated often occurs, affecting cooking efficiency.

[0083] To solve the above problems, please refer to Figure 1 、 Figure 2 as well as Figure 3 The present invention provides a grilling machine 100.

[0084] In one embodiment of the present invention, the grilling machine 100 includes a base 11 assembly 10 and an upper cover assembly 30; wherein, the base 11 assembly 10 includes a base 11 and a grilling pan 12, and the grilling pan 12 is rotatably arranged on the base 11; the upper cover assembly 30 includes an upper cover 31 and a light wave tube 32, the upper cover 31 is connected to the base 11, and can be opened or closed on the base 11, and the light wave tube 32 is arranged on the upper cover 31 and is located on the side of the upper cover 31 facing the grilling pan 12.

[0085] In one embodiment of the present invention, the base 11 can be used to mount components such as the baking tray 12 and the rotating member 13, allowing the various components of the base 11 assembly 10 to be assembled into a single unit. The projection of the base 11 on a horizontal plane can be roughly rectangular or square, making the base 11 more regular and easier to manufacture. Of course, the present application is not limited to this. In other embodiments, the projection of the base 11 on a horizontal plane can also be circular or have other shapes. To enhance the stability of the baking tray 12 mounted on the base 11, the base 11 can be formed with a receiving cavity 111 having an opening, within which the baking tray 12 can be rotatably positioned. The projection of the receiving cavity 111 on a horizontal plane can be circular, allowing the baking tray 12 to be configured in a corresponding circular shape. This allows the shape of the receiving cavity 111 to better match the shape of the baking tray 12, thereby improving the compactness of the distribution between the base 11 and the baking tray 12 and ensuring that the walls of the receiving cavity 111 guide the baking tray 12 during rotation. Of course, the present application is not limited to this. In other embodiments, the base 11 may be relatively large, and the projection of the accommodating cavity 111 on a horizontal plane may be square or other shapes, so long as the grilling tray 12 can rotate within the accommodating cavity 111. The grilling tray 12 can be used to accommodate food to be heated and, after being heated, transfer heat to the food on the grilling tray 12. The grilling tray 12 may be cylindrical, in which case it may include a bottom wall 121 and side walls 123. The side walls 123 are annular, with one of their two open ends connected to the surface of the bottom wall 121 facing away from the bottom wall of the accommodating cavity 111. The accommodating space enclosed by the bottom wall 121 and side walls 123 can effectively contain food and reduce the possibility of food spilling during the rotation of the grilling tray 12. To ensure smooth rotation and minimize space usage, the horizontal projection of the bottom wall 121 and side walls 123 can be circular. Of course, if there is sufficient space within the accommodating cavity 111 of the base 11, the horizontal projection of the bottom wall 121 and side walls 123 can also be square. Alternatively, in other embodiments, the grilling pan 12 may only have the bottom wall 121. The upper cover 31 can be opened or closed with respect to the base 11, allowing the grilling pan 12 to be positioned within the relatively enclosed space formed by the upper cover 31 and the base 11. This reduces heat loss within the cooking space, thereby improving cooking efficiency for the ingredients in the grilling pan 12. If the base 11 is formed with an accommodating cavity 111 for accommodating the grilling pan 12, the upper cover 31 can open or close the opening of the accommodating cavity 111 as it moves relative to the base 11. Of course, when the base 11 is not formed with the accommodating cavity 111 , the surface of the upper cover 31 facing the baking tray 12 may be concave, so as to cover the baking tray 12 disposed on the base 11 .In addition, the upper cover 31 and the base 11 can be connected in a rotating or sliding manner, so that the base 11 can be opened and closed by rotating or sliding the upper cover 31. Of course, the present application is not limited to this. In other embodiments, the upper cover 31 and the base 11 may not have a connection relationship and only cover the base 11. The light wave tube 32 can be used to provide a light wave heat source for the food to heat the food located in the baking tray 12. The light wave tube can be provided on the surface of the upper cover 31 facing the base 11, or it can be embedded in the upper cover 31. In this case, the upper cover 31 can be provided with a light-transmitting hole on the surface facing the baking tray 12.

[0086] The grilling machine 100 of the present invention rotatably mounts the grilling pan 12 of the base 11 assembly 10 on the base 11. This allows the grilling pan 12 to rotate relative to the base 11 during cooking, causing the food within the grilling pan 12 to rotate relative to the light wave tube 32 of the upper cover assembly 30. This ensures more uniform heating of the food within the grilling pan 12, reducing the risk of burning, and thereby improving the cooking performance of the grilling machine 100.

[0087] Furthermore, the grilling machine 100 of this embodiment uses the light wave tube 32 of the upper cover assembly 30 to provide a light wave heat source to heat the food in the grilling pan 12. This allows for rapid generation of high heat during the cooking process, improving heating efficiency and reducing the risk of burning, thereby ensuring the color of the food. This further enhances the cooking effect of the grilling machine 100.

[0088] Please refer to Figures 3 to 7 In one embodiment of the present invention, the base 11 assembly 10 further includes a rotating member 13, which is disposed on the base 11 and has a clearance fit with the baking tray 12. When the rotating member 13 drives the baking tray 12 to rotate relative to the base 11, the rotating member 13 abuts against the baking tray 12 for transmission.

[0089] It can be understood that the rotating member 13 and the grilling pan 12 have a clearance fit, and only engage and drive the grilling pan 12 when rotating the grilling pan 12 relative to the base 11. In this case, when a large amount of food is placed on the grilling pan 12, the base 11 assembly 10's driving member 15 has room for movement during startup due to the clearance fit between the rotating member 13 and the grilling pan 12. This allows the rotating member 13 to engage and drive the grilling pan 12 loaded with large food only after startup and normal operation. This reduces the possibility of the driving member 15 encountering significant resistance during startup due to a large amount of food on the grilling pan 12, causing it to jam and heat, leading to damage. This ensures the normal and stable operation of the grilling machine 100. The rotating member 13 can be located on the bottom wall of the accommodating chamber 111 to drive the bottom wall 121 of the grilling pan 12; however, it can also be located on the side walls of the accommodating chamber 111 to drive the side walls 123 of the grilling pan 12. In addition, the rotating member 13 may be partially located in the accommodating cavity 111 , or may be entirely located in the accommodating cavity 111 .

[0090] Please refer to Figures 4 to 6 In one embodiment of the present invention, in the rotation direction of the baking tray 12 relative to the base 11, there is a first gap between the rotating member 13 and the baking tray 12, and the rotating member 13 can rotate in the first gap.

[0091] It is understood that a first gap is formed between the rotating member 13 and the baking tray 12 directly in the direction of the baking tray 12's rotation, which allows the movement path of the rotating member 13 to be more compatible with the first gap. In this case, when the driving member 15 of the base 11 assembly 10 is activated, the rotating member 13 can rotate within the first gap for a certain period of time, so that the driving member 15 driving the rotating member 13 has sufficient buffer space for movement, thereby further ensuring that the driving member 15 is not subject to the resistance created by the rotation of the baking tray 12 until it is started and operating normally. Of course, the present application is not limited to this. In other embodiments, a certain gap can be formed between the rotating member 13 and the baking tray 12 when the baking tray 12 is upward relative to the rotation axis 144 of the base 11. For example, the driven portions of the rotating member 13 and the baking tray 12 are both configured as inclined planes or inclined arcs.

[0092] Please refer to Figure 5 and Figure 6 In one embodiment of the present invention, a positioning member 125 is provided on the wall of the baking tray 12 facing the rotating member 13, and a first gap is formed between the rotating member 13 and the positioning member 125. When the rotating member 13 is driven, it can abut and drive the positioning member 125 to rotate the baking tray 12 relative to the base 11.

[0093] It can be understood that the transmission is achieved solely through the abutment between the positioning member 125 and the rotating member 13, eliminating the need for a complex structure on the baking tray 12, thereby simplifying the structure of the baking tray 12 and ensuring its inherent strength. Furthermore, the positioning member 125 is located on the surface of the baking tray 12 facing the bottom wall of the accommodating cavity 111 (also known as the bottom wall 121 of the baking tray 12), thereby achieving a more compact arrangement between the baking tray 12 and the rotating member 13, thereby reducing the overall volume of the base 11 assembly 10. Of course, the present application is not limited to this. In other embodiments, the wall surface of the baking tray 12 facing the cavity side wall of the accommodating cavity 111 may be provided with a positioning member 125 (it can also be said to be the tray side wall 123 of the baking tray 12). In this case, the rotating member 13 can be provided on the cavity side wall of the accommodating cavity 111; or, the tray bottom wall 121 of the baking tray 12 facing the cavity bottom wall of the accommodating cavity 111 is formed with an abutment groove, and a portion of the rotating member 13 extends into the abutment groove and is clearance-matched with the groove side wall of the abutment groove, and then abuts with the groove side wall of the abutment groove for transmission when driven.

[0094] Please refer to Figure 5 and Figure 6 In one embodiment of the present invention, the rotating member 13 includes a connecting column 131 and an abutment block 133. One end of the connecting column 131 is rotatably provided on the wall surface of the base 11 facing the baking tray 12, and the other end is extended in the direction toward the baking tray 12; the abutment block 133 is connected to the end of the connecting column 131 away from the base 11, and is arranged at an angle to the connecting column 131. A first gap is formed between the abutment block 133 and the positioning member 125, and the abutment block 133 can abut and drive the positioning member 125.

[0095] It can be understood that the rotating member 13 can be well connected to the driving member 15 of the base 11 assembly 10 through the connecting column 131, and the abutment block 133 can make the rotation axis 144 of the rotating member 13 have a certain distance from the positioning member 125 and have a certain driving torque, so that the rotating member 13 can drive the positioning member 125 when it is driven. At the same time, such a configuration also allows the rotating member 13 to achieve different functions through different parts (i.e., connection and limitation through the connecting column 131, and abutment and driving through the abutment block 133), which can make the various parts of the rotating member 13 be correspondingly configured to simplify the overall structure of the rotating member 13 and ensure the overall strength of the rotating member 13. The rotating member 13 may be located at the center of the accommodating chamber 111, and the positioning member 125 may be arranged offset from the center of the accommodating chamber 111. In this case, the middle or end portion of the abutting block 133 may abut the positioning member 125 to drive the positioning member 125. Of course, the rotating member 13 may also be arranged offset from the center of the accommodating chamber 111, and the positioning member 125 may be located at the center of the accommodating chamber 111. In this case, the end surface of the abutting block 133 away from the end of the connecting column 131 may abut the positioning member 125 to drive the positioning member 125. In addition, it should be noted that in other embodiments, the rotating member 13 may also include only the connecting column 131, the lower end of which may be used to connect to the driving member 15 of the base 11 assembly 10, and the upper end may be used to abut and drive the positioning member 125. At this time, the matching relationship between the upper end of the connecting column 131 and the abutment member can be: the side surface of the upper end of the connecting column 131 is provided with an abutment groove, the positioning member 125 is accommodated in the abutment groove and can be abutted and driven by the groove wall of the abutment groove.

[0096] Please refer to Figure 7 In one embodiment of the present invention, the rotation angle formed by the abutting block 133 rotating in the first gap is defined as α, which satisfies the condition: 5°≤α≤80°.

[0097] It is understood that when the rotation angle α formed by the rotation of the abutment block 133 within the first gap is less than 5°, the amount of rotation of the abutment block 133 within the first gap is relatively small, which may affect the movement and buffering effect of the driving member 15 during startup. When the rotation angle α formed by the rotation of the abutment block 133 within the first gap is greater than 80°, the amount of rotation of the abutment block 133 within the first gap is relatively large, which may cause the abutment block 133 to rotate for a longer time before abutting and driving the positioning member 125, thereby affecting the efficiency of driving the baking tray 12. Therefore, in order to balance the movement and buffering effect of the driving member 15 of the base 11 assembly 10 and the driving efficiency of the baking tray 12, the rotation angle α formed by the rotation of the abutment block 133 within the first gap is set to 5°≤α≤80°. Among them, the rotation angle α formed by the rotation of the abutment block 133 in the first gap 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 in the above range.

[0098] Please refer to Figure 6 In one embodiment of the present invention, there are multiple abutment blocks 133, which are spaced apart around the center line of the connecting column 131; there are multiple positioning members 125, which are spaced apart around the center line of the baking tray 12, and an abutment block 133 is provided between each two adjacent positioning members 125, and a first gap is formed between each abutment block 133 and the positioning member 125 adjacent to the abutment block 133.

[0099] It will be appreciated that the arrangement of the multiple abutment blocks 133 and the multiple positioning members 125 allows various parts of the baking tray 12 to be driven in the circumferential direction of rotation by the abutment and cooperation between the multiple abutment blocks 133 and the multiple positioning members 125, thereby facilitating rapid and relatively stable driving of the baking tray 12 by the rotating member 13. Furthermore, this arrangement ensures that the rotating member 13 can abut and drive the positioning members 125 when driven, thereby effectively ensuring the driving of the baking tray 12 by the rotating member 13. This also improves the overall strength of the rotating member 13, reducing the likelihood of fracture due to abutment and driving of the positioning members 125, thereby extending the service life of the rotating member 13. Furthermore, the driving member 15 that drives the rotating member 13 can be a bidirectional synchronous motor, so that when the abutment blocks 133 of the rotating member 13 encounter resistance from one of the two adjacent positioning members 125 when rotating in one direction, they can rotate in the opposite direction. Thus, when installing the baking tray 12 in the accommodating cavity 111, it is sufficient to ensure that one abutting block 133 is inserted into both positioning members 125, eliminating the need to adjust the placement angle of the baking tray 12 along the circumferential direction. Of course, the driving member 15 may also be a unidirectional motor. In this case, when installing the baking tray 12 in the accommodating cavity 111, after one abutting block 133 is inserted into both positioning members 125, the baking tray 12 is rotated in a direction opposite to the rotation direction of the driving member 15 until the abutting block 133 abuts one positioning member 125. This ensures that when the driving member 15 is activated, the abutting block 133 can rotate between the two positioning members 125, thereby ensuring normal activation of the driving member 15.

[0100] In one embodiment of the present invention, the rotating member 13 also includes a fixed seat 135, which is connected to one end of the connecting column 131 away from the bottom wall of the accommodating cavity 111. The projection of the fixed seat 135 on the horizontal plane covers the projection of the connecting column 131 on the horizontal plane, and multiple abutment blocks 133 are all connected to the fixed seat 135.

[0101] It is understood that the connecting column 131 connects the multiple abutting blocks 133 via the relatively large fixing seat 135. The relatively large fixing seat 135 has a larger connection position, thereby facilitating the connection and fixation of the multiple abutting blocks 133. At the same time, the provision of the fixing seat 135 is also conducive to further improving the overall strength of the rotating member 13.

[0102] Please refer to Figure 7 In one embodiment of the present invention, the projection of the fixing seat 135 on the horizontal plane is circular, and the plurality of positioning members 125 are all in contact with the side surface of the fixing seat 135 .

[0103] It will be appreciated that the multiple positioning members 125 abut against the side surfaces of the fixing seat 135, allowing the abutment of the side surfaces of the fixing seat 135 to limit the multiple positioning members 125 during rotation, thereby improving the stability of the baking tray 12 during rotation. The fixing seat 135 has a circular projection on a horizontal plane, so that its side surfaces align with the rotational trajectory of the positioning members 125. This reduces the possibility of the fixing seat 135 obstructing the multiple positioning members 125 during rotation, thereby ensuring smooth rotation of the positioning members 125. In this case, the centers of the multiple positioning members 125 are located on concentric circles, which also facilitates uniform driving force at all locations of the baking tray 12, allowing for relatively stable rotation. Of course, the present application is not limited to this. In other embodiments, only the side surface of the fixing seat 135 may be set as an arc surface with different radius at the position corresponding to each positioning member 125. In this case, the center of each positioning member 125 can be located on a different circular path; or, the fixing seat 135 is set to be square or rectangular, etc., and has a gap with multiple positioning members 125.

[0104] Please refer to Figure 7 In one embodiment of the present invention, the projection of the abutting block 133 on the horizontal plane is a square or a rectangle.

[0105] It is understood that this arrangement makes the two opposing side surfaces of the abutment block 133 relatively flat, enabling better abutment with the positioning member 125, thereby ensuring the stability of the abutment block 133 in driving the positioning member 125. Furthermore, the square or rectangular projection of the abutment block 133 on the horizontal plane also makes the shape of the abutment block 133 relatively regular, thereby facilitating the processing and manufacturing of the abutment block 133.

[0106] Please refer to Figure 8 In one embodiment of the present invention, the distance between the two opposite side walls of the abutting block 133 increases in the direction away from the fixing seat 135. This allows the side walls of the abutting block 133 to exert an abutting force on the positioning member 125 toward the center of the accommodating cavity 111, thereby reducing the possibility of the positioning member 125 slipping out from between the two abutting blocks 133 during the driving process, and further improving the stability of the positioning member 125 being abutted and driven by the abutting blocks 133.

[0107] In one embodiment of the present invention, the connecting column 131, the fixing seat 135 and the abutting block 133 are an integrated structure;

[0108] It is understood that the connecting column 131, the fixing seat 135, and the abutment block 133 are integrally configured to increase the connection strength at the connection point, thereby further improving the overall strength of the rotating member 13. At the same time, this configuration also allows the components to be manufactured through an integrated molding process, simplifying the processing and improving production efficiency. Of course, the present application is not limited to this. In other embodiments, the connecting column 131, the fixing seat 135, and the abutment block 133 can also be separate structures and can be bonded and fixed using glue, or fixed using buckles, screws, etc.

[0109] Please refer to Figure 4 and Figure 6 In one embodiment of the present invention, the base 11 assembly 10 further includes a support structure 14, which is disposed between the base 11 and the baking tray 12 and supported by the baking tray 12, so that the connecting column 131 and the abutment block 133 have a second gap in the axial direction of the connecting column 131.

[0110] It can be understood that the support structure 14 provides abutment and support against the baking tray 12, so that the rotating member 13 is not affected by the compressive force of the baking tray 12, and is only subject to the circumferential resistance of the positioning member 125 during driving. This reduces the resistance encountered by the driving member 15 of the base 11 assembly 10 when driving the rotating member 13, further reducing the possibility of the driving member 15 getting stuck due to excessive force during startup. At the same time, this arrangement also reduces the possibility of heat from the baking tray 12 being heated and transferred to the driving member 15 through the rotating member 13, thereby improving the protection of the driving member 15. The support structure 14 can be provided on the base 11, on the baking tray 12, or independently of the base 11 and baking tray 12, and located only between them.

[0111] Please refer to Figure 4 and Figure 6 In one embodiment of the present invention, a support protrusion 141 is provided on the wall surface of the base 11 facing the baking tray 12 . The support protrusion 141 forms a support structure 14 , and the support protrusion 141 abuts against and supports the baking tray 12 .

[0112] It can be understood that by supporting the bottom wall 121 of the baking tray 12 with the support protrusions 141, the support structure 14 can fully bear the weight of the baking tray 12 in the direction opposite to gravity, thereby improving the support effect of the support structure 14 on the baking tray 12. At the same time, the relatively simple structure of the support protrusions 141 also facilitates the molding of the support structure 14. In addition, it should be noted that in other embodiments, the support protrusions 141 can also be provided on the side walls of the accommodating cavity 111.

[0113] In one embodiment of the present invention, the cross-sectional area of ​​the supporting protrusion 141 is reduced in a direction from the bottom wall of the accommodating cavity 111 of the base 11 to the cavity opening of the accommodating cavity 111 .

[0114] It can be understood that the cross-sectional area of ​​support protrusion 141 is smaller at the top and larger at the bottom, which reduces the contact area between support protrusion 141 and grilling tray 12 and reduces friction generated during rotation, thereby improving the smoothness of driving grilling tray 12. This also ensures a more stable connection between support protrusion 141 and base 11, ensuring the strength of the connection between support protrusion 141 and base 11, thereby improving the supporting effect of support protrusion 141. Of course, the present application is not limited to this embodiment. In other embodiments, the cross-sectional area of ​​support protrusion 141 can be equal in the direction from the bottom wall of accommodating cavity 111 to the cavity opening of accommodating cavity 111.

[0115] In one embodiment of the present invention, a first chamfer is formed at a connection between a surface of the supporting protrusion 141 facing away from the bottom wall of the accommodating cavity 111 and a side surface of the supporting protrusion 141 .

[0116] It is understood that the first chamfer can reduce the possibility of sharp corners forming at the edges of the support protrusion 141, thereby preventing stress concentration and the possibility of cracking. At the same time, this arrangement can further reduce the contact area between the support protrusion 141 and the bottom wall 121 of the baking tray 12, thereby further reducing wear between the two.

[0117] In one embodiment of the present invention, a second chamfer is formed at the connection between the side surface of the supporting protrusion 141 and the bottom wall of the accommodating cavity 111 .

[0118] It can be understood that the provision of the second chamfer strengthens the connection between the support protrusion 141 and the base 11, thereby further improving the stability of the connection between the support protrusion 141 and the base 11. Furthermore, the support protrusion 141 and the base 11 can be formed into an integral structure to further enhance the connection strength between the two and improve the supporting effect of the support protrusion 141. At the same time, it also allows the support protrusion 141 and the base 11 to be manufactured through integral molding, simplifying the processing of both and improving production efficiency. The first chamfer and the second chamfer can both be rounded, or of course, beveled.

[0119] In one embodiment of the present invention, the cross section of the supporting protrusion 141 is circular.

[0120] It is understood that the cylindrical shape of the support protrusion 141 can make its shape more regular, thereby facilitating the processing and forming of the support protrusion 141. This also ensures that the side surface of the support protrusion 141 is consistent, ensuring that the support effect of the support protrusion 141 on different parts of the baking tray 12 does not vary depending on the installation orientation. Of course, the present application is not limited to this. In other embodiments, the cross-section of the support protrusion 141 can also be square or rectangular, etc.

[0121] Please refer to Figure 4 and Figure 15 In one embodiment of the present invention, there are multiple supporting protrusions 141, and the ends of the multiple supporting protrusions 141 facing away from the bottom wall of the accommodating cavity 111 are all supported on the surface of the bottom wall of the baking tray 12 facing the accommodating cavity 111.

[0122] It can be understood that by providing abutment and support for the baking tray 12 using multiple support protrusions 141, the weight of the baking tray 12 can be dispersed across each support protrusion 141. This results in a relatively small compressive force on each support protrusion 141, thereby reducing the possibility of damage to the support protrusions 141. Furthermore, the provision of multiple support protrusions 141 allows for abutment and support at various locations on the bottom wall 121 of the baking tray 12, thereby improving the stability of the support for the baking tray 12.

[0123] In one embodiment of the present invention, the plurality of supporting protrusions 141 are distributed in a circular array around the center line of the accommodating cavity 111 .

[0124] It is understood that this arrangement allows the distribution path of the multiple support protrusions 141 to match the rotation path of the grilling pan 12, ensuring uniform friction between the grilling pan 12 and the support protrusions 141 during rotation, thereby facilitating uniform rotation of the grilling pan 12 and uniformly heating the food on the grilling pan 12. Of course, the present application is not limited to this, and in other embodiments, the multiple support protrusions 141 may be distributed in a rectangular array.

[0125] In one embodiment of the present invention, the support protrusions 141 located on the same circumferential path are defined as a support protrusion group, and the plurality of support protrusions 141 form at least two support protrusion groups.

[0126] Please refer to Figure 22 and Figure 23 In one embodiment of the present invention, a roller 142 is provided on the wall of the base 11 facing the baking tray 12 . The roller 142 forms the supporting structure 14 , and the roller 142 abuts against and supports the baking tray 12 .

[0127] It is understood that by abutting the support grilling pan 12 with roller 142, rolling friction is generated between the grilling pan 12 and the support structure 14. This reduces the friction experienced by the grilling pan 12 when rotating relative to the base 11, thereby improving the smoothness of the grilling pan 12's rotation and reducing wear during rotation, thereby extending the service life of the grilling pan 12 and the support structure 14. The roller 142 can be secured by the support structure 14 further comprising a fixing block 143 and a rotating shaft 144. The fixing block 143 and the base 11 cooperate to clamp and secure the rotating shaft 144, and the roller 142 is sleeved on the rotating shaft 144.

[0128] In one embodiment of the present invention, the roller 142 is rotatably embedded in the surface of the base 11 where the opening of the accommodating cavity 111 is formed.

[0129] It will be appreciated that the rollers 142 are disposed on the surface of the base 11 where the cavity 111 is formed, allowing the support structure 14 to support the edge of the baking tray 12. This reduces the possibility of the baking tray 12 tilting or shaking in the vertical direction, thereby improving the stability of the support provided by the multiple rollers 142 to the baking tray 12. The embedded arrangement of the rollers 142 allows for a more compact installation on the base 11, reducing space requirements. Of course, the present application is not limited to this embodiment. In other embodiments, the rollers 142 may be rotatably disposed within the cavity 111, as long as they can support the bottom wall 121 or the side walls 123 of the baking tray 12. Furthermore, to ensure uniform support of the rollers 142 at all locations on the baking tray 12, the rollers 142 may be evenly spaced around the centerline of the cavity 111. At this time, the roller 142 abuts against the side wall 123 of the baking tray 12. In order to facilitate the abutment of multiple rollers 142 against the baking tray 12, the side wall 123 of the baking tray 12 may include a surrounding plate 1231 and a flange 1233. The surrounding plate 1231 is formed with an opening at one end connected to the bottom wall 121 of the tray, and the flange 1233 is connected to the end of the surrounding plate 1231 away from the bottom wall 121 of the tray, and surrounds the outer side of the surrounding plate 1231, and the roller 142 can abut against the flange 1233.

[0130] Please refer to Figure 19 、 Figure 20 as well as Figure 21 In one embodiment of the present invention, the side wall of the accommodating chamber 111 is recessed near the cavity opening of the accommodating chamber 111 to form a mounting platform 1633 step. The mounting platform 1633 step is arranged in a ring shape around the center line of the accommodating chamber 111, and the roller 142 is rotatably embedded in the bottom wall of the mounting platform 1633 step.

[0131] It can be understood that the setting of the mounting platform 1633 steps provides a mounting position for the roller 142, so that the roller 142 can be located on the inner side of the base 11, reducing the possibility of foreign objects clogging or damaging the roller 142. At the same time, the mounting platform 1633 steps can accommodate and limit a portion of the plate side wall 123 of the baking tray 12 (which can be the flange 1233 of the plate side wall 123 of the baking tray 12), thereby helping to further improve the stability of the baking tray 12 during rotation.

[0132] Please refer to Figure 19 、 Figure 20 as well as Figure 21 In one embodiment of the present invention, the support structure 14 further includes a rotating ring 145 . The rotating ring 145 surrounds the outer side of the baking tray 12 , and the rotating ring 145 abuts against the baking tray 12 and the roller 142 .

[0133] It is understood that by abutting the roller 142 at its lower end and the baking tray 12 (which can be the flange 1233 of the sidewall 123 of the baking tray 12) at its upper end, the baking tray 12 is supported on a surface. This helps ensure support for the baking tray 12 and reduces the possibility of the baking tray 12 tilting or shaking in the vertical direction. The swivel ring 145 can be mounted on a step 1633 of the mounting platform 1633 to limit the position of the swivel ring 145.

[0134] Please refer to Figure 24 、 Figure 25 as well as Figure 26 In one embodiment of the present invention, a main ball bearing 147 is provided on the wall surface of the base 11 facing the baking tray 12 . The main ball bearing 147 forms the supporting structure 14 , and the main ball bearing 147 abuts against and supports the baking tray 12 .

[0135] It is understood that the spherical shape of the main ball bearing 147 allows it to rotate freely within the horizontal and vertical planes. When the baking tray 12 deviates from the preset rotational path during rotation, rolling friction can occur between the main ball bearing 147 and the baking tray 12, thereby reducing the resistance caused by the main ball bearing 147 to the baking tray 12 during rotation. To facilitate installation and management of the main ball bearing 147, the support structure 14 may further include a mounting seat 146 disposed on the wall of the accommodating cavity 111. The mounting seat 146 defines an accommodating cavity 1461, which has a through-hole 1463 facing the baking tray 12. The main ball bearing 147 is disposed within the mounting cavity 112 and partially exposed outside the mounting seat 146 through the through-hole 1463 of the accommodating cavity 1461. The main ball bearing 147 exposed outside the mounting seat 146 abuts against the baking tray 12. Furthermore, the support structure 14 includes a plurality of auxiliary balls 148 disposed within the accommodating cavity 1461 and positioned below the primary ball 147. The auxiliary balls 148 cooperate with the mounting seat 146 to clamp and position the primary ball 147. The auxiliary balls 148 provide support and abutment against the primary ball 147, increasing the contact area with the primary ball 147 and thereby improving the stability of the primary ball 147 within the accommodating cavity 1461. The diameter of the auxiliary balls 148 is smaller than that of the primary ball 147, allowing them to abut various areas of the lower spherical surface of the primary ball 147.

[0136] Please refer to Figures 7 to 10 In one embodiment of the present invention, the projection of the positioning member 125 on the horizontal plane is circular, square, rectangular or sector-shaped.

[0137] It is understood that when the positioning member 125 is arranged in a cylindrical shape, it facilitates the contact between the positioning member 125 and the fixed seat 135 of the rotating member 13, and can reduce friction between the two. At the same time, such an arrangement also makes the side circumferences of the multiple positioning members 125 consistent, which can facilitate the uniformity of the contact force of each contact block 133 on each positioning member 125 (the magnitude of each contact force is consistent and the direction is tangential to the rotation path of the positioning member 125). When the projection of the positioning member 125 on the horizontal plane is a square, rectangular or sector-shaped, the shape of the positioning member 125 can be made relatively regular, thereby facilitating its processing and manufacturing.

[0138] In one embodiment of the present invention, the positioning member 125 and the baking tray 12 are an integral structure.

[0139] It is understood that the positioning member 125 and the baking tray 12 are integrally provided, which can enhance the strength of the connection between the two, thereby reducing the possibility of the positioning member 125 breaking when abutted and driven by the abutment block 133. At the same time, it also allows the two to be manufactured through an integral molding, simplifying the processing technology of both and improving production efficiency.

[0140] Please refer to Figure 4 、 Figure 5 as well as Figure 6 In one embodiment of the present invention, the base 11 assembly 10 further includes a driving member 15 and a transmission structure 16. The driving member 15 is provided on the base 11. The transmission structure 16 is transmission-connected to the driving member 15 and the connecting column 131. The driving member 15 drives the connecting column 131 to rotate through the transmission structure 16.

[0141] It will be appreciated that the configuration of transmission structure 16 allows drive member 15 to drive rotating member 13 via transmission structure 16 . This prevents heat from the grilling pan 12 from being directly transferred to drive member 15 via rotating member 13, thereby reducing the possibility of damage to drive member 15 . Furthermore, the indirect drive of rotating member 13 by drive member 15 adjusts the rotational speed of rotating member 13, thereby ensuring a reasonable rotational speed when grilling pan 12 is driven by rotating member 13 , allowing the food on grilling pan 12 to be heated evenly and effectively. Furthermore, this configuration allows drive member 15 to be horizontally staggered from rotating member 13, reducing the vertical space occupied by both, thereby helping to reduce the overall volume of base 11 assembly 10 . Of course, it should be noted that the present application is not limited to this embodiment. In other embodiments, drive member 15 may be directly connected to the end of connecting column 131 away from abutment block 133 .

[0142] In one embodiment of the present invention, a mounting cavity 112 is further formed in the base 11, and the base 11 is further provided with a clearance hole 113 connecting the mounting cavity 112 and the accommodating cavity 111, and the end of the connecting column 131 away from the abutment block 133 extends into the mounting cavity 112 through the clearance hole 113; the base 11 assembly 10 also includes a driving member 15, and the driving member 15 and the transmission structure 16 are both arranged in the mounting cavity 112, and the transmission structure 16 is transmission-connected to the connecting column 131 extending into the mounting cavity 112.

[0143] It can be understood that the installation cavity 112 provides space for the driver 15 and its installation, allowing the driver 15 and transmission structure 16 to be more compactly positioned relative to the base 11, thereby reducing the overall size of the base 11 assembly 10. Furthermore, the installation cavity 112 also provides a certain degree of isolation and protection for the driver 15, reducing the risk of damage to the driver 15 due to exposure. Of course, this is not a limitation of the present application; even if the base 11 does not have a mounting cavity 112, the driver 15 and transmission structure 16 can be located within the accommodating cavity 111. Furthermore, to enhance the controllability of the grilling machine 100, a circuit board 1120 can be provided within the installation cavity 112. This circuit board 1120 is electrically connected to the driver 15, allowing the circuit board 1120 to control the operating state of the driver 15, such as start, pause, or speed.

[0144] Please refer to Figure 4 and Figure 5 In one embodiment of the present invention, the transmission structure 16 includes a driving gear 161 and a driven gear 163 . The driving gear 161 is connected to the driving member 15 , and the driven gear 163 is connected to the connecting column 131 and meshes with the driving gear 161 .

[0145] It can be understood that the gear transmission has the advantages of high transmission efficiency, smooth transmission, high transmission accuracy and large transmission torque, so that the high efficiency and smoothness of the driving of the rotating member 13 can be ensured, thereby facilitating the rotating member 13 to further drive the baking tray 12 effectively, smoothly and efficiently. Of course, it should be noted that the present application is not limited to this. In other embodiments, the transmission structure 16 may also include a worm and a worm wheel, the worm is connected to the driving member 15, and the worm wheel is connected to the connecting column 131 and meshes with the worm. Alternatively, the transmission structure 16 may also include a driving wheel, a driven wheel and a conveyor belt, the driving wheel is connected to the driving member 15, the driven wheel is connected to the connecting column 131, and the conveyor belt is sleeved on the driving wheel and the driven wheel.

[0146] Please refer to Figure 11 、 Figure 12 as well as Figure 13 In one embodiment of the present invention, the transmission structure 16 further includes a mounting frame 165 . The mounting frame 165 is disposed in the mounting cavity 112 . The driving member 15 , the driving gear 161 , and the driven gear 163 are all disposed on the mounting frame 165 .

[0147] It will be appreciated that the provision of mounting bracket 165 allows the driver 15, driving gear 161, and driven gear 163 to be first mounted on mounting bracket 165, and then secured within mounting cavity 112, thereby simultaneously securing multiple components to base 11. The relatively simple structure and compact size of mounting bracket 165 facilitate the installation of driver 15, driving gear 161, and driven gear 163, thereby enhancing the convenience of mounting and securing transmission structure 16. The projection of mounting bracket 165 on a horizontal plane can be roughly rectangular, so that the driving gear 161 and driven gear 163 are distributed along the length of mounting bracket 165.

[0148] Please refer to Figure 12 and Figure 13 In one embodiment of the present invention, the mounting frame 165 is defined as having an upper surface and a lower surface that are opposite to each other, and the driving gear 161 and the driven gear 163 are both arranged on the upper surface of the mounting frame 165; the driving member 15 is arranged on the lower surface of the mounting frame 165, and partially passes through the mounting frame 165 and is inserted into the driven gear 163.

[0149] It will be appreciated that positioning the driving gear 161 and the driven gear 163 on the upper surface of the mounting bracket 165, while positioning the driving member 15 on the lower surface of the mounting bracket 165, allows the driven gear 163 and the connecting post 131 to be relatively close together, thereby facilitating their connection. Furthermore, by making the connecting post 131 relatively short, the stability of the mounting of the rotating member 13 and the stability of its contact with the positioning member 125 are improved. The output shaft of the driving member 15 passes through the mounting bracket 165 and is securely connected to the driving gear 161.

[0150] In one embodiment of the present invention, a connecting plate 151 is provided on a side circumference of the driving member 15 , a connecting seat 1651 is provided on a side circumference of the mounting bracket 165 , and the connecting plate 151 is connected to the connecting seat 1651 .

[0151] It will be appreciated that the connection plate 151 provides a mounting location, allowing a connecting structure to be provided on the connection plate 151 to secure the driver 15, thereby reducing the possibility that the provision of the connecting structure will affect the structure of the driver 15 itself. The provision of the connecting seat 1651 facilitates the connection between the connecting structure provided on the connection plate 151 and the mounting bracket 165. Furthermore, to improve the stability of the installation of the driver 15, the connecting seat 1651 can be supported by abutting against the connection plate 151. To allow the driver 15 to be disassembled and repaired in the event of damage, the connection plate 151 and the connecting seat 1651 can be detachably connected, specifically, by screw connection, snap connection, or magnetic fixation.

[0152] Please refer to reference 13 and Figure 14 In one embodiment of the present invention, a positioning groove 1653 is formed in a recessed manner on the lower surface of the mounting frame 165 , and at least a portion of the driving member 15 is embedded in the positioning groove 1653 .

[0153] It can be understood that the positioning groove 1653 has a certain limiting effect on the driver 15, reducing the possibility of the driver 15 shifting on the mounting bracket 165, thereby improving the stability of the installation of the driver 15. At the same time, the positioning groove 1653 also provides a certain amount of accommodation space, which can accommodate at least part of the driver 15, thereby making the driver 15 more compactly distributed on the mounting bracket 165 and reducing the space occupied by the driver 15 on the mounting bracket 165. Of course, the present application is not limited to this embodiment. In other embodiments, the driver 15 can also be attached to the lower surface of the mounting bracket 165.

[0154] In one embodiment of the present invention, a limiting groove 1611 is formed on the surface of the driving gear 161 facing the mounting bracket 165. The limiting groove 1611 is annular and is disposed around the rotation axis 144 of the driving gear 161. A limiting ring 1655 is protruded from the upper surface of the mounting bracket 165 and is embedded in the limiting groove 1611.

[0155] It can be understood that the cooperation between limiting groove 1611 and limiting ring 1655 has a limiting effect on the installation of driving gear 161, thereby ensuring that driving gear 161 is accurately installed in the predetermined installation position. At the same time, during the rotation of driving gear 161, limiting groove 1611 also guides limiting ring 1655, so that driving gear 161 can accurately rotate along the predetermined trajectory and accurately drive driven gear 163.

[0156] In one embodiment of the present invention, a mounting post 1631 is protruded from the surface of the driven gear 163 facing the mounting bracket 165 . A mounting groove 1657 is recessed on the upper surface of the mounting bracket 165 , and the mounting post 1631 is rotatably disposed in the mounting groove 1657 .

[0157] It can be understood that the installation limit of the driven gear 163 is achieved by plugging and fitting the mounting column 1631 and the mounting groove 1657, so that the two do not need to be connected with a more complicated structure, while also ensuring that the driven gear 163 has a certain strength for better transmission.

[0158] In one embodiment of the present invention, the transmission structure 16 further includes a bearing 167 . The bearing 167 is disposed in the mounting groove 1657 , and the mounting post 1631 is inserted into the bearing 167 .

[0159] It can be understood that by connecting the mounting post 1631 and the mounting bracket 165 via the bearing 167, a more complex structure is not required within the mounting groove 1657. The bearing 167 can simply be placed within the mounting groove 1657 and interference fit with the sidewalls of the mounting groove 1657. Similarly, the mounting post 1631 can simply be inserted into the bearing 167 and interference fit with the inner ring 1673 of the bearing 167, further simplifying the connection structure between the two. Of course, the present application is not limited to this. In other embodiments, when the transmission structure 16 does not include the bearing 167, a snap-fit ​​groove is formed in the sidewall of the mounting groove 1657. The portion of the mounting post 1631 inserted into the mounting groove 1657 is embedded in the snap-fit ​​groove, allowing the mounting post 1631 to rotate circumferentially within the mounting groove 1657 while being axially limited.

[0160] In one embodiment of the present invention, the bearing 167 includes an outer ring 1671 and an inner ring 1673. The outer ring 1671 is connected to the base 11, and the inner ring 1673 is rotatably embedded in the inner ring 1673. The inner ring 1673 is provided with a gasket 169 at one end of the slot facing away from the mounting groove 1657. The gasket 169 is connected to the mounting column 1631.

[0161] It can be understood that by having the washer 169 abut against the inner ring 1673 of the bearing 167 and connected to the mounting post 1631, the stability of the mounting post 1631 can be further improved. That is, in addition to the interference fit with the inner ring 1673 to limit its position, the washer 169 also limits its position. The washer 169 and the mounting post 1631 can be connected by screws to simplify the connection effect and the connection process. Furthermore, the bottom wall of the mounting groove 1657 is provided with a mounting opening 1658, and the washer 169 is embedded in the mounting opening 1658, so that the washer 169 can be installed through the mounting opening 1658, thereby improving the convenience of installing the washer 169.

[0162] In one embodiment of the present invention, a mounting platform 1633 is protruded from the surface of the driven gear 163 away from the mounting frame 165, and a plug hole 1635 is provided on the surface of the mounting platform 1633 away from the driven gear 163, and the end of the rotating member 13 away from the baking tray 12 is inserted into the plug hole 1635.

[0163] It can be understood that the relatively close proximity of mounting platform 1633 and connecting post 131 further facilitates the connection between driven gear 163 and connecting post 131. Furthermore, since mounting platform 1633 can be configured to a certain height, insertion hole 1635 can also be configured to a certain depth, ensuring the insertion clearance of connecting post 131 within mounting platform 1633, thereby increasing the contact area between the two and improving the stability of the connection between connecting post 131 and driven gear 163. The portion of connecting post 131 inserted into mounting platform 1633 can be configured to have a non-circular shape to enhance the tightness of the fit between the two. Furthermore, the screw connecting gasket 169 to mounting post 1631 can pass through mounting post 1631 and into insertion hole 1635, where it can be connected to connecting post 131, further enhancing the stability of the connection between connecting post 131 and mounting platform 1633.

[0164] Please refer to Figure 5 and Figure 11 In one embodiment of the present invention, a top wall of the installation cavity 112 is recessed to form an avoidance groove 1121 , and the driving gear 161 and the driven gear 163 are accommodated in the avoidance groove 1121 .

[0165] It can be understood that the avoidance groove 1121 has an avoidance effect on the driving gear 161 and the driven gear 163, so that the distance between the transmission structure 16 and the cavity top wall of the installation cavity 112 can be set to be smaller, thereby further reducing the space occupied by the transmission structure 16 in the installation cavity 112. The shape of the avoidance groove 1121 can be set to roughly match the shape of the mounting bracket 165, and can be specifically configured adaptively as needed to ensure that the driving gear 161 and the driven gear 163 can be avoided.

[0166] In one embodiment of the present invention, a connecting ear 1659 is further provided on the side surface of the mounting frame 165 , and a fixing post 1123 is protruding from the top wall of the mounting cavity 112 , and the connecting ear 1659 is connected to the fixing post 1123 .

[0167] It will be appreciated that connecting ear 1659 provides a mounting location, allowing for a connecting structure to be disposed on connecting ear 1659 for securing mounting bracket 165 to the top wall of mounting cavity 112. This reduces the impact of this connecting structure on driving gear 161 and driven gear 163 located on the upper surface of mounting bracket 165, and on driving member 15 located on the lower surface of mounting bracket 165. The provision of fixing post 1123 facilitates the connection between the connecting structure disposed on connecting ear 1659 and base 11. Furthermore, to enhance the stability of mounting bracket 165, fixing post 1123 can abut against connecting ear 1659 for support. To allow mounting bracket 165 to be disassembled and repaired in the event of damage, connecting ear 1659 and fixing post 1123 can be detachably connected, specifically by screws, snaps, or magnetic fastening.

[0168] Please refer to Figure 4 and Figure 5 In one embodiment of the present invention, the base 11 includes a base body 114 and a lower reflective plate 115. A accommodating cavity 111 with a cavity opening, an installation cavity 112, and a clearance hole 113 are formed in the base body 114. The lower reflective plate 115 is arranged in the accommodating cavity 111 and is at least partially located between the baking tray 12 and the bottom wall of the accommodating cavity 111; the connecting column 131 has an abutment block 133 at one end located between the baking tray 12 and the lower reflective plate 115, and the end away from the abutment block 133 passes through the lower reflective plate 115 and the clearance hole 113 and extends into the installation cavity 112.

[0169] It is understood that the lower reflective plate 115 can reflect heat below the grilling pan 12, reducing heat loss within the accommodating cavity 111 from being lost to the outside through the base 11, thereby improving the utilization efficiency of the heat within the accommodating cavity 111 and enhancing the heating efficiency of the grilling machine 100 for food. The lower reflective plate 115 can be connected to the base body 114, specifically by a snap-fit ​​connection or screw connection. The lower reflective plate 115 can be positioned solely between the grilling pan 12 and the bottom wall of the accommodating cavity 111; of course, it can also be positioned partially between the grilling pan 12 and the bottom wall of the accommodating cavity 111 and partially between the grilling pan 12 and the side walls of the accommodating cavity 111 (in this case, the lower reflective plate 115 can be generally cylindrical and generally conform to the shape of the accommodating cavity 111). The support structure 14 can be a sidewall of the accommodating cavity 111 provided on the base body 114, or a surface of the base body 114 where the cavity opening of the accommodating cavity 111 is formed, or a wall provided on the lower reflective plate 115 facing the baking tray 12. Furthermore, to facilitate the formation of the mounting cavity 112, the base body 114 can include a base upper shell 1141 and a base lower shell 1143. The base upper shell 1141 forms the accommodating cavity 111. The base lower shell 1143 is connected to the side of the base upper shell 1141 facing away from the cavity opening of the accommodating cavity 111 and, together with the base upper shell 1141, forms the mounting cavity 112. The clearance hole 113 is provided in the base upper shell 1141. In this manner, the base upper shell 1141 and the base lower shell 1143 are manufactured separately and assembled to form a whole after each is formed and manufactured. The base upper shell 1141 and the base lower shell 1143 can be detachably connected, specifically by screws, snaps, or magnetic fixation. In this case, the fixing column 1123 and the avoidance groove 1121 are provided on the surface of the base upper shell 1141 facing the base lower shell 1143, and the mounting bracket 165 is connected to the base upper shell 1141.

[0170] In one embodiment of the present invention, a gap is defined between the lower reflective plate 115 and the base body 114 , so that a heat-insulating cavity 116 is formed between the lower reflective plate 115 and the base body 114 .

[0171] It can be understood that the provision of the heat-insulating cavity 116 has a blocking effect on heat transfer, which can reduce the possibility of heat in the accommodating cavity 111 entering the mounting cavity 112, thereby facilitating improved protection of components such as the driver 15 and the circuit board 1120 located in the mounting cavity 112. Of course, the present application is not limited to this, and in other embodiments, the lower reflective plate 115 can also be attached to the cavity wall of the accommodating cavity 111.

[0172] In one embodiment of the present invention, the base 11 assembly 10 further includes a lower heating element 17 . The lower heating element 17 is disposed on a wall surface of the lower reflective plate 115 facing the baking tray 12 .

[0173] It can be understood that the lower heating element 17 is arranged on the wall surface of the lower reflective plate 115 facing the baking tray 12, so that the distance between the lower heating element 17 and the baking tray 12 is relatively close, thereby being able to better heat the food in the baking tray 12. At the same time, the lower reflective plate 115 can also timely reflect the heat, so as to transfer as much heat as possible to the baking tray 12 to quickly heat the food. Specifically, when the lower reflective plate 115 is provided with support protrusions 141, the lower heating element 17 can be located between two adjacent support protrusion groups. In addition, there can be a certain gap between the lower heating element 17 and the baking tray 12 to reduce the wear caused by the baking tray 12 during the rotation process, thereby helping to improve the protection of the lower heating element 17.

[0174] Please refer to Figure 4 、 Figure 5 as well as Figure 15 In one embodiment of the present invention, a wall surface of the lower reflective plate 115 facing the lower heating element 17 is recessed to form a groove 1151 , the groove 1151 is arranged around the center line of the accommodating cavity 111 , and the lower heating element 17 is embedded in the groove 1151 .

[0175] It can be understood that the setting of the groove 1151 provides space for accommodating the lower heating element 17. In this way, when the lower reflective plate 115 and the bottom wall 121 of the baking tray 12 are set relatively close, a gap can also be formed between the lower heating element 17 embedded in the groove 1151 and the baking tray 12, which is conducive to ensuring that there is a gap between the lower heating element 17 and the baking tray 12.

[0176] Please refer to Figure 15 and Figure 16 In one embodiment of the present invention, the lower heating element 17 includes a heating tube 171, which includes a first tube section 1711 and two second tube sections 1713. The first tube section 1711 is arranged in a ring shape and has gaps formed at both ends. The first tube section 1711 is located in the groove 1151 and has a gap between it and the surface of the cavity bottom wall of the baking tray 12 facing the accommodating cavity 111; one end of the two second tube sections 1713 is respectively connected to the two ends of the first tube section 1711, and the other end is extended in the direction facing the groove bottom wall of the groove 1151.

[0177] It can be understood that the two second tube sections 1713 of the lower heating element 17 extend in the direction of the bottom wall of the groove facing the groove 1151, which can reduce the space occupied by the lower heating element 17 on the horizontal plane and simplify the complexity of the processing of the groove 1151. At the same time, the two second tube sections 1713, as electrical terminals, can pass through the lower reflective plate 115 and the base upper shell 1141 of the base body 114 and extend into the installation cavity 112, so that the conductive electrical appliance connected to them is located in the installation cavity 112, reducing the possibility of heat in the accommodating cavity 111 damaging the conductive electrical appliance. Of course, the present application is not limited to this. In other embodiments, it is also possible for the lower heating element 17 to only have the first tube section 1711 arranged in a ring shape. Alternatively, the lower heating element 17 can also be a heating wire.

[0178] Please refer to Figure 16 and Figure 17 The lower heating element 17 further includes a bracket 173, which is sleeved on the first pipe section 1711 and connected to the groove wall of the groove 1151. There is a gap between the bracket 173 and the surface of the bottom wall of the baking tray 12 facing the accommodating cavity 111.

[0179] It can be understood that by connecting the bracket 173 and the lower reflective plate 115 that are sleeved on the first tube section 1711, the support and fixation of the heat pipe 171 can be achieved, which can reduce the possibility of damage to the heat pipe 171 when it is fixed, thereby improving the safety of the installation of the heat pipe 171. Among them, the bracket 173 can be detachably connected to the bottom wall of the groove 1151, specifically by screw connection, snap connection or magnetic fixation, so as to simplify the disassembly and assembly process of the lower heating element 17. In order to improve the stability of the sleeve between the heat pipe 171 and the bracket 173, the cross-section of the first tube section 1711 can be set in a non-circular shape, for example, it can be square, rectangular or triangular. In addition, the number of brackets 173 can be multiple, and the multiple brackets 173 can be spaced apart along the circumferential direction of the groove 1151 to provide more stable support for the first tube section 1711.

[0180] Please refer to Figure 16 In one embodiment of the present invention, the bracket 173 is formed with a revealing hole 1731 on the surface facing the baking tray 12 , and the revealing hole 1731 passes through the inner side and the outer side of the bracket 173 .

[0181] It can be understood that the provision of exposure hole 1731 can reduce the contact area between first tube segment 1711 of heating tube 171 and bracket 173, thereby reducing the degree to which first tube segment 1711 transfers heat to lower reflective plate 115 via bracket 173, thereby improving the utilization rate of the heat generated by first tube segment 1711. Furthermore, the heat generated by first tube segment 1711, located below exposure hole 1731, can be effectively transferred to grilling pan 12 through exposure hole 1731.

[0182] Please refer to Figure 16 and Figure 18 In one embodiment of the present invention, the lower heating element 17 further includes a flange 175 , which is sleeved on the two second pipe sections 1713 and connected to the bottom wall of the groove 1151 .

[0183] It is understood that the connection between the flange 175 and the bottom wall of the groove 1151 also provides a position-limiting and securing effect on the second tube segment 1713, thereby improving the overall stability of the fixing of the heat pipe 171. The connection between the flange 175 and the bottom wall of the groove 1151 can be detachable, allowing the heat pipe 171 to be removed from the lower reflector 115 for repair and replacement in the event of damage. For example, the flange 175 and the bottom wall of the groove 1151 can be connected by screws, snaps, or magnetic fastening.

[0184] Please refer to Figures 27 to 30 In one embodiment of the present invention, a heat dissipation channel 311 is formed in the upper cover 31 , and the light wave tube 32 is located outside the heat dissipation channel 311 .

[0185] It will be appreciated that by providing a heat dissipation channel 311 within the upper cover 31, external air can enter the upper cover 31 through the heat dissipation channel 311. Therefore, when the heat emitted by the light wave tube 32 attempts to dissipate toward the outside of the upper cover 31, it can be carried away by the air within the heat dissipation channel 311, thereby reducing the possibility of the upper cover 31 overheating and effectively reducing the risk of burns to the user. Furthermore, to improve the flow of air within the heat dissipation channel 311, an exhaust device 33 can be provided within the heat dissipation channel 311 to drive external air through the heat dissipation channel 311. The exhaust device 33 can be a fan, blower, or induced draft fan, etc.

[0186] Please refer to Figure 29 and Figure 30 In one embodiment of the present invention, the upper cover assembly 30 further includes an upper reflective cover 34, which is connected to the upper cover 31 and is located on the side of the upper cover 31 facing the baking tray 12; the upper reflective cover 34 and the upper cover 31 together form a heat dissipation channel 311, and the light wave tube 32 is located on the side of the upper reflective cover 34 facing away from the heat dissipation channel 311.

[0187] As can be understood, the upper reflector 34 is capable of reflecting the heat from the lightwave tube 32, directing the dissipated heat toward the grilling pan 12 of the grilling machine 100. Therefore, when the heat from the lightwave tube 32 attempts to transfer outward to the exterior or surface of the upper cover 31, most of it is reflected back by the upper reflector 34. The small amount of heat that does escape is also carried away by the airflow within the heat dissipation duct. This improves heat utilization while preventing the formation of high temperatures on the cover surface. The upper reflector 34 can be a circular structure with its opening facing the grilling pan 12. The lightwave tube 32 can be located on the wall of the upper reflector 34 directly opposite the opening. Furthermore, the upper reflector 34 can be configured with a smaller cross-section at the top and a larger cross-section at the bottom. This creates a stepped surface on the side of the upper reflector 34, which blocks the airflow within the heat dissipation duct 311, prolonging the time the airflow remains within the heat dissipation duct 311 and improving the heat dissipation efficiency of the upper cover 31.

[0188] In one embodiment of the present invention, the upper cover assembly 30 further includes a heat shield 35, which is connected to the upper reflective cover 34 and is located on the side of the upper reflective cover 34 away from the light wave tube 32. The heat shield 35, the upper reflective cover 34 and the upper cover 31 together form a heat dissipation channel 311.

[0189] It can be understood that the provision of the heat shield 35 can block heat that passes through the upper reflector 34. As a result, the dissipated heat can avoid being blocked by the upper reflector 34, the heat shield 35, and the heat dissipation channel 311, and can be ventilated and dissipated, forming a triple protection to ensure that the upper cover 31 does not generate high temperatures. The heat shield 35 can also have a circular cover structure and can be mounted on the upper end of the upper reflector 34, which has a relatively small cross-section.

[0190] In one embodiment of the present invention, the upper cover assembly 30 further includes a protective cover 36 . The protective cover 36 is connected to the reflective cover and encloses a placement cavity 361 . The light wave tube 32 is located in the placement cavity 361 .

[0191] It can be understood that the provision of the protective cover 36 ensures that heat from the light wave tube 32 within the cavity 361 is properly transferred while also preventing users from accidentally touching the light wave tube 32. The protective cover 36 can be a microporous plate structure having multiple micropores to allow heat to pass through. The protective cover 36 can be detachably secured to the wall of the upper reflector 34 opposite its opening by means of a snap or buckle connection.

[0192] Please refer to Figure 30 、 Figure 31 as well as Figure 32In one embodiment of the present invention, the upper cover 31 is further provided with an air inlet 312 and an air outlet 313, both of which are connected to the heat dissipation channel 311; the vertical height of the openings of the air inlet 312 and / or the air outlet 313 located in the upper cover 31 is higher than the vertical height of the openings at the other end.

[0193] It will be appreciated that this arrangement prevents liquid adhering to the outer wall of the upper cover 31 from entering the upper cover 31 through the air inlet 312 or air outlet 313, thereby significantly improving the waterproof performance of the grill 100 and preventing safety risks caused by water ingress. The air inlet 312 and air outlet 313 can have the same or different shapes and sizes. For example, the air inlet 312 and air outlet 313 can both be circular or square. The air inlet 312 and air outlet 313 can be located on the top wall of the upper cover 31 or on the side walls of the upper cover 31. Furthermore, the air inlet 312 and air outlet 313 can be located on one surface of the upper cover 31 or on two separate surfaces, in which case they can be adjacent or opposite to each other.

[0194] Please refer to Figure 31 and Figure 32 In one embodiment of the present invention, the angle between the center line of the air inlet 312 or the air outlet 313 and the horizontal line is β, which satisfies the relationship: 5°≤β≤45°.

[0195] It is understandable that the angle β should not be too large or too small. If it is too large, the inclination angle of the air inlet 312 or the air outlet 313 is too large, so that when the air in the upper cover 31 is discharged through the air outlet 313, or when the fresh air from the outside enters through the air inlet 312, the corner of the air circulation path is too large, which is not conducive to the smooth circulation of air. If it is too small, the height of the openings at both ends of the air inlet 312 or the air outlet 313 will be close, and the air inlet 312 or the air outlet 313 will tend to be flat, which will make it easy for external water or oil to enter the upper cover 31 through the air inlet 312 or the air outlet 313. This increases the risk of water ingress. Therefore, in this embodiment, the angle β is set within a range of not less than 5° and not more than 45°.

[0196] Please refer to Figure 29 、 Figure 31 as well as Figure 32 In one embodiment of the present invention, the upper cover assembly 30 further includes a multi-layer window structure 37. The multi-layer window structure 37 is provided on the upper cover 31 and is enclosed with the upper cover 31 to form a light-transmitting and heat-insulating cavity 38. The light-transmitting and heat-insulating cavity 38 and the heat dissipation channel 311 are arranged at intervals.

[0197] It will be appreciated that with this arrangement, when the grilling tray 12 rotates relative to the upper cover 31, it also rotates relative to the multi-layered window structure 37. This allows the user to see the cooking status and degree of the food from all directions through the multi-layered window structure 37, preventing the food from being burnt or overcooked. Furthermore, the multi-layered window structure 37 and the upper cover 31 enclose a light-transmitting, heat-insulating cavity 38. This cavity not only allows the user to observe the cooking process of the food, but also prevents the transfer of heat and moisture, preventing the outer surface of the multi-layered window structure 37 from overheating. This prevents burns from the user touching the outer surface of the multi-layered window structure 37, thereby improving the convenience and safety of the grilling machine 100. Among them, the multi-layer window structure 37 can be arranged at intervals from the light wave tube 32, that is, a visible area 31A and a heating area 31B can be set side by side on the upper cover 31, and the light wave tube 32 and the multi-layer window structure 37 are respectively arranged relative to the heating area 31B and the visible area 31A, so that the structural arrangement between the light wave tube 32 and the multi-layer window structure 37 is compact and reasonable, thereby effectively reducing the difficulty of assembling and disassembling the light wave tube 32 and the multi-layer window structure 37 separately, and effectively avoiding the situation where the volume of the upper cover assembly 30 is too large due to unreasonable arrangement. At the same time, the partitioned arrangement of the visible area 31A and the heating area 31B can effectively avoid the light wave tube 32 from blocking the visible area 31A of the multi-layer window structure 37.

[0198] Please refer to Figure 33 and Figure 34 In one embodiment of the present invention, the upper cover 31 is defined to have a connecting end 314, and the connecting end 314 is rotatably connected to the base 11. When the upper cover 31 rotates relative to the base 11, it can be opened or covered on the base 11, and the multi-layer window structure 37 is located on the side of the upper cover 31 away from the connecting end 314.

[0199] It is understood that the multi-layered window structure 37 is located on the side of the cover body away from the connecting end 314. Thus, when the user closes the cover 31, the multi-layered window structure 37 is closer to the user's body, making it easier for the user to observe the cooking process inside the grill 100 through the multi-layered window structure 37. The connecting end 314 is rotatably connected to the base body 114 of the base 11.

[0200] In one embodiment of the present invention, the upper cover 31 is provided with a first clearance opening 315 and a second clearance opening 316 on a side away from the connection end 314. The second clearance opening 316 is located above the first clearance opening 315, and the first and second clearance openings 315, 316 are at least partially arranged opposite each other. The multi-layer window structure 37 includes a first window 371 and a second window 373. The first window 371 is embedded in the first clearance opening 315, and the second window 373 is embedded in the second clearance opening 316.

[0201] Specifically, the upper cover 31 is provided with a first and second openings 315, 316 that communicate with each other, and the first and second windows 371, 373 are adapted to fit within the openings 315, 316, respectively, so that the first and second windows 371, 373 can be directly embedded within the openings 315, 316. This facilitates the positioning and installation of the first and second windows 371, 373 of the multi-layer window structure 37, improving both initial installation efficiency and subsequent maintenance and disassembly efficiency. Furthermore, the second window 373 is located on the outer surface of the upper cover 31, allowing the user to observe the grilling process of food within the grill 100 through both the second and first windows 373, respectively. Furthermore, the light-transmitting and heat-insulating cavity 38 prevents the transfer of heat and moisture, thereby preventing the second window 373, located on the outer surface of the upper cover 31, from overheating, thus ensuring user safety.

[0203] Specifically, the first shell 317 and the second shell 318 can be detachably connected by a snap-fit ​​connection, etc., to facilitate the later maintenance and replacement of the internal parts of the upper cover 31. The first shell 317 and the second shell 318 enclose a light-transmitting and heat-insulating cavity 38, and the first clearance opening 315 is located on the bottom wall of the light-transmitting and heat-insulating cavity 38, while the second clearance opening 316 is located on the side wall of the light-transmitting and heat-insulating cavity 38. The first window 371 and the second window 373 are respectively embedded in the first clearance opening 315 and the second clearance opening 316, so that the user can observe the cooking status of the food on the baking tray 12 from the second side window 373 toward the first bottom window 371. The second window 373 is located on the side wall to prevent moisture from migrating upward from the light-transmitting and heat-insulating cavity 38 and adhering to the second window 373, thereby achieving good anti-fog performance and ensuring the visual effect of the multi-layer window structure 37. In addition, the second window 373 can be connected to the first shell 317 and the second shell 318 respectively by means of snaps or screws. In this embodiment, the specific installation process is: the bottom of the second window 373 can be snapped and positioned with the first shell 317 by means of snaps, and at the same time, a screw hole is set at the top of the second window 373, and the second window 373 is connected to the second shell 318 by passing the screw through the screw hole, so as to achieve the connection and fixation between the first shell 317, the second shell 318 and the second window 373, thereby ensuring the stability of the upper cover assembly 30 after assembly. In addition, when the upper cover 31 includes a first shell 317 and a second shell 318, the first shell 317 may have a connection end 314 and be rotatably connected to the base body 114 of the base 11; the second shell 318 may cover the side of the first shell 317 facing away from the base 11; the upper reflector 34 may be connected to the surface of the first shell 317 facing away from the second shell 318. In this case, the second shell 318, the first shell 317, the upper reflector 34, and the heat shield 35 may enclose and form a heat dissipation channel 311, and the air inlet 312 and the air outlet 313 may be respectively provided on two opposite side walls of the second shell 318. Furthermore, the upper cover 31 may also include a decorative plate 319, which may be connected to the top surface of the second shell 318 (or the wall facing away from the first shell 317). The decorative plate 319 may be attached to the top surface of the second shell 318 or removably fixed to the top surface of the second shell 318 using a snap. The decorative plate 319 can decorate the appearance of the upper cover assembly 30 to facilitate user identification, thereby improving the aesthetic appearance and enhancing the market competitiveness of the product.

[0204] Please refer to Figure 33 and Figure 34In one embodiment of the present invention, the upper cover assembly 30 further includes a buffer structure 39, which is provided on at least one of the base 11 and the upper cover 31 and can be used to provide a buffer force when the upper cover 31 is opened or closed on the base 11.

[0205] It can be understood that the design of the buffer structure 39 provides a buffering force during the process of opening or closing the upper cover 31 and the base 11, thereby buffering the impact force during opening or closing. Therefore, even when the upper cover assembly 30 is heavy, it will not cause strong impact during the state change between opening and closing with the base 11, thereby effectively preventing damage to the upper cover 31 and the base 11 during opening or closing, and avoiding safety accidents such as pinching fingers. Among them, the buffer structure 39 can be provided solely on the first shell 317 of the upper cover 31 or on the base body 114 of the base 11, or it can be provided partially on the first shell 317 of the upper cover 31 and the other part on the base body 114 of the base 11. It should be noted that the buffering force provided by the buffer structure 39 can be used to buffer the impact force when the two are closed together, or it can be used to buffer the impact force after the upper cover 31 and the base 11 are opened to a preset angle.

[0206] Please refer to Figure 34 and Figure 35 In one embodiment of the present invention, the connection end 314 is provided with a hinge shaft 3141, and the buffer structure 39 is a damper 391. The damper 391 is sleeved on the outer side of the hinge shaft 3141 and is connected to the base 11 so that when the connection end 314 rotates relative to the base 11, the upper cover 31 opens or covers the base 11.

[0207] It is understood that the damper 391 can be a hydraulic damper 391, which includes a sleeve 3911 and a shaft core 3913 disposed within the sleeve 3911. The outer wall of the sleeve 3911 extends to form a mounting portion 3915, which is connected and fixed to the base body 114 of the base 11 via the mounting portion 3915. The hinge shaft 3141 passes through the shaft core 3913 within the sleeve 3911. The shaft core 3913 is provided with a partition 3917. The partition 3917 divides the space within the sleeve 3911 into two parts, and the partition 3917 defines a liquid hole 3919 that connects the two spaces. Hydraulic oil is contained in both spaces. Therefore, when the upper cover 31 is flipped relative to the base 11, the hinge shaft 3141 rotates along with the upper cover 31. At this time, the hinge shaft 3141 drives the shaft core 3913 and the partition 3917 on the shaft core 3913 to rotate together. In this way, during the rotation of the partition 3917, while squeezing the hydraulic oil, the hydraulic oil also acts as a reverse push on the partition 3917, thereby forming a buffering effect. Among them, the damper 391 is connected to the base body 114 of the base 11. Of course, in other embodiments, the damper 391 can also be a structure commonly used in the prior art, such as an elastic damper 391. Using the damper 391 as the buffer structure 39 can buffer the impact of the heavier upper cover assembly 30 and has strong reliability.
