Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a base assembly and a cooking utensil using the base assembly. Background Art

[0002] To ensure uniform heating of ingredients during use, cooking appliances in the related art often feature a rotatable grill plate. This rotation ensures uniform heating of the ingredients. However, when a large amount of ingredients is placed on the grill plate, the loaded grill plate creates significant resistance to the cooking appliance's drive, which in turn takes time to activate and function properly. This significant resistance from the grill plate during activation can easily cause the drive to become stuck, overheat, and damage, preventing the cooking appliance from functioning properly. Summary of the Invention

[0003] The main purpose of the present invention is to provide a base assembly for use in cooking appliances, which is intended to provide a buffered movement space for the driving member of the cooking appliance during startup, thereby reducing the possibility of the driving member being stuck and heated due to the large resistance encountered by the driving member during startup due to the large amount of food placed on the baking tray, thereby ensuring the normal and stable operation of the cooking appliance.

[0004] To achieve the above objectives, the base assembly proposed by the present invention includes:

[0005] A base, wherein the base is formed with a receiving cavity having a cavity opening;

[0006] a baking tray rotatably disposed in the accommodating cavity; and

[0007] The rotating member is arranged in the accommodating cavity and has a clearance fit with the baking tray. When the rotating member drives the baking tray to rotate relative to the base, the rotating member abuts against the baking tray for transmission.

[0008] In one embodiment of the present invention, in the rotation direction of the baking tray relative to the base, a first gap is defined between the rotating member and the baking tray, and the rotating member is rotatable within the first gap.

[0009] In one embodiment of the present invention, a positioning member is provided on the surface of the bottom wall of the baking tray facing the accommodating cavity, and the first gap is formed between the rotating member and the positioning member. When the rotating member is driven, it can abut and drive the positioning member to cause the baking tray to rotate relative to the base.

[0010] In one embodiment of the present invention, the rotating member comprises:

[0011] a connecting post, one end of which is rotatably disposed on the bottom wall of the accommodating cavity, and the other end of which is extended toward the cavity opening of the accommodating cavity; and

[0012] The abutment block is connected to one end of the connecting column away from the bottom wall of the accommodating cavity and is arranged at an angle to the connecting column. The first gap is formed between the abutment block and the positioning member, and the abutment block can abut and drive the positioning member.

[0013] In one embodiment of the present invention, there are multiple abutment blocks, and the multiple abutment blocks are spaced apart and distributed around the center line of the connecting column;

[0014] There are multiple positioning members, and the multiple positioning members are spaced apart around the center line of the baking tray. An abutment block is provided between each two adjacent positioning members, and the first gap is formed between each abutment block and the positioning member adjacent to the abutment block.

[0015] In one embodiment of the present invention, the rotation angle formed by the rotation of the abutting block between two adjacent positioning members is defined as α, which satisfies the condition: 5°≤α≤80°.

[0016] In one embodiment of the present invention, the rotating member also includes a fixed seat, which is connected to one end of the connecting column away from the bottom wall of the accommodating cavity, and the projection of the fixed seat on the horizontal plane covers the projection of the connecting column on the horizontal plane, and the plurality of abutment blocks are all connected to the fixed seat.

[0019] And / or, the connecting column, the fixing seat and the abutment block are an integrated structure;

[0020] And / or, the plurality of abutment blocks are connected to the side circumferential surface of the fixing seat, and a second gap is formed between the surfaces of the plurality of abutment blocks and the fixing seat facing away from the connecting column and the surface of the bottom wall of the baking tray facing the accommodating cavity.

[0021] And / or, the projection of the positioning element on the horizontal plane is circular, square, rectangular or sector-shaped;

[0022] And / or, the positioning member and the baking tray are an integrated structure.

[0023] In one embodiment of the present invention, a mounting cavity is further formed in the base, and a clearance hole is further provided in the base for connecting the mounting cavity and the accommodating cavity, and an end of the connecting column away from the abutting block extends into the mounting cavity through the clearance hole;

[0024] The base assembly further includes a driving member, which is disposed in the installation cavity and connected to the connecting column extending into the installation cavity. The driving member can drive the connecting column to rotate.

[0025] In one embodiment of the present invention, the base assembly further includes a transmission structure, which is disposed in the installation cavity and is transmission-connected to the driving member and the connecting column, and the driving member drives the connecting column to rotate through the transmission structure.

[0026] In one embodiment of the present invention, the transmission structure includes:

[0027] A driving gear, the driving gear being sleeved on the driving member; and

[0028] The driven gear is sleeved on the connecting column extending into the installation cavity, and the driven gear is meshed with the driving gear.

[0029] In one embodiment of the present invention, the base comprises:

[0030] A base body, wherein a receiving cavity with a cavity opening, the installation cavity and the clearance hole are formed in the base body; and

[0031] a lower reflective plate, the lower reflective plate being disposed in the accommodating cavity and at least partially located between the baking tray and the bottom wall of the accommodating cavity;

[0032] One end of the connecting column provided with the abutting block is located between the baking tray and the lower reflective plate, and the other end away from the abutting block passes through the lower reflective plate and the passing hole and extends into the installation cavity.

[0033] In one embodiment of the present invention, a gap is provided between the lower reflective plate and the base body, so that a heat-insulating cavity is formed between the lower reflective plate and the base body;

[0034] And / or, the base assembly further includes a lower heating element, and the lower heating element is arranged on the wall surface of the lower reflective plate facing the baking pan.

[0035] The present invention also provides a cooking appliance, comprising:

[0036] A base assembly, the base assembly comprising a base, a baking tray, and a rotating member, the base forming a receiving cavity with a cavity opening; the baking tray being rotatably disposed in the receiving cavity; the rotating member being disposed in the receiving cavity and having a clearance fit with the baking tray, such that when the rotating member drives the baking tray to rotate relative to the base, the rotating member abuts against the baking tray for transmission; and

[0037] The upper cover assembly is connected to the base of the base assembly and can open or cover the cavity opening of the accommodating cavity.

[0038] In one embodiment of the present invention, the upper cover assembly includes:

[0039] an upper cover connected to the base and capable of opening or closing the opening of the accommodating cavity; and

[0040] The upper heating element is arranged on the wall surface of the upper cover facing the bottom wall of the accommodating cavity.

[0041] When the base assembly of the present invention is used in a cooking appliance, food can be placed on the base assembly's baking tray. The driver then drives the rotating member to rotate, which in turn abuts against the baking tray, thereby evenly heating the food on the baking tray and achieving uniform heating of the food by the cooking appliance. Furthermore, because the rotating member of the base assembly and the baking tray in this embodiment have a clearance fit, the rotating member abuts against the baking tray only when rotating the baking tray relative to the base. In this case, when a large amount of food is placed on the baking tray, the driver has room to move during startup due to the clearance fit between the rotating member and the baking tray. This allows the rotating member to abut against and drive the baking tray, even if the food is large, only after the driver has started and is operating normally. This reduces the risk of the driver encountering significant resistance during startup due to a large amount of food on the baking tray, causing it to jam and heat, potentially leading to damage. This ensures normal and stable operation of the cooking appliance. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Please refer to Figures 1 to 6 The present invention provides a base assembly 10 that can be applied to a cooking utensil 100, which can be a grill or a microwave oven.

[0077] In one embodiment of the present invention, the base assembly 10 includes a base 11, a baking tray 12, and a rotating member 13. The base 11 is formed with a receiving cavity 111 having an opening; the baking tray 12 is rotatably disposed within the receiving cavity 111; and the rotating member 13 is disposed within the receiving cavity 111 and is clearance-fitted 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.

[0078] In one embodiment of the present invention, the base 11 can be mainly used to install parts such as the baking tray 12 and the rotating member 13, so that the various parts of the base assembly 10 can be assembled to form a whole. The projection of the base 11 on the horizontal plane can be roughly rectangular or square, so that the shape of the base 11 is relatively regular and easy to form and manufacture. Of course, the present application is not limited to this. In other embodiments, the projection of the base 11 on the horizontal plane can also be circular or other shapes. The projection of the accommodating cavity 111 formed by the base 11 on the horizontal plane can be circular, so that the baking tray 12 can be set to a circular shape accordingly, and the shape of the accommodating cavity 111 can be more compatible with the shape of the baking tray 12, thereby improving the compactness of the distribution between the base 11 and the baking tray 12, and the guidance of the cavity wall of the accommodating cavity 111 to the baking tray 12 during the rotation process. 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 the 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 primarily used to accommodate food to be heated, and after being heated, it can also transfer heat to the food on the grilling tray 12. The grilling tray 12 can 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, reducing 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 sufficient space is available within the accommodating cavity 111, the horizontal projection of the bottom wall 121 and side walls 123 can also be square. Alternatively, in other embodiments, the baking tray 12 may only have the bottom wall 121. The rotating member 13 is primarily configured for transmission connection with the driving member 15 of the cooking appliance 100, and when driven, drives the baking tray 12 to rotate relative to the base 11. The rotating member 13 can be located on the bottom wall of the accommodating cavity 111 to drive the bottom wall 121 of the baking tray 12; it can also be located on the side walls of the accommodating cavity 111 to drive the side walls 123 of the baking tray 12. Furthermore, the rotating member 13 can be partially or entirely located within the accommodating cavity 111.

[0079] When the base assembly 10 of the present invention is used in a cooking appliance 100, food can be placed on the baking tray 12 of the base assembly 10. The driving member 15 then drives the rotating member 13 to rotate. The rotating member 13 abuts against the baking tray 12, thereby evenly heating the food on the baking tray 12 and achieving uniform heating of the food by the cooking appliance 100. Furthermore, because the rotating member 13 of the base assembly 10 and the baking tray 12 of this embodiment are clearance-fitted, the rotating member 13 abuts against the baking tray 12 only when the baking tray 12 is rotated relative to the base 11. In this case, when a large amount of food is placed on the baking tray 12, the clearance fit between the rotating member 13 and the baking tray 12 provides a buffer for movement when the driving member 15 is activated. This allows the rotating member 13 to abut against and drive the baking tray 12, even if the food is larger, only after the driving member 15 has started and is operating normally. This reduces the possibility that the driving member 15 will be blocked and heated, resulting in damage, when it is started due to greater resistance caused by placing more food on the baking tray 12, thereby ensuring the normal and stable operation of the cooking appliance 100.

[0080] Please refer to Figure 4 and Figure 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.

[0081] 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 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 starts and operates 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.

[0082] Please refer to Figure 4 and Figure 6 In one embodiment of the present invention, a positioning member 125 is provided on the surface of the bottom wall of the baking tray 12 facing the accommodating cavity 111, 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 make the baking tray 12 rotate relative to the base 11.

[0083] 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 the strength of the baking tray 12. Furthermore, the positioning member 125 is located on the surface of the bottom wall of the baking tray 12 facing the accommodating cavity 111 (also known as the bottom wall 121 of the baking tray 12), which allows for a more compact distribution between the baking tray 12 and the rotating member 13, thereby reducing the overall volume of the base 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 dish 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 cavity bottom wall of the baking tray 12 facing the accommodating cavity 111 is formed with an abutment groove, and a portion of the rotating member 13 extends into the abutment groove and has a clearance fit 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.

[0084] Please refer to Figure 4 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 bottom wall of the accommodating chamber 111, and the other end extends toward the cavity opening of the accommodating chamber 111; the abutment block 133 is connected to one end of the connecting column 131 away from the bottom wall of the accommodating chamber 111, 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.

[0085] It can be understood that the rotating member 13 can be preferably connected to the driving member 15 of the base assembly 10 through the connecting column 131, and the abutment block 133 can ensure that the rotation axis 144 of the rotating member 13 is at a certain distance from the positioning member 125, thereby generating a certain driving torque, so that the rotating member 13 can drive the positioning member 125 when 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 enable the corresponding configuration of various parts of the rotating member 13, thereby simplifying the overall structure of the rotating member 13 and ensuring the overall strength of the rotating member 13. Among them, the rotating member 13 may be located at the center of the accommodating chamber 111, and the positioning member 125 may be set away 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 set away 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 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, 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.

[0086] Please refer to Figure 4 and 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.

[0087] 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 the two 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 the two 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 against one of the two positioning members 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.

[0088] Please refer to Figure 4 、 Figure 6 as well as Figure 7 In one embodiment of the present invention, the rotation angle formed by the abutment block 133 rotating between two adjacent positioning members 125 is defined as α, which satisfies the condition: 5°≤α≤80°.

[0089] It is understood that when the rotation angle α formed by the rotation of the abutment block 133 between two adjacent positioning members 125 is less than 5°, the rotational clearance between the two positioning members 125 is small, which affects the movement buffering effect of the driving member 15 during startup. When the rotation angle α formed by the rotation of the abutment block 133 between two adjacent positioning members 125 is greater than 80°, the rotational clearance between the two positioning members 125 is large, causing the abutment block 133 to rotate for a long time before abutting and driving the positioning members 125, thereby affecting the efficiency of driving the baking tray 12. Therefore, in order to balance the movement buffering effect of the driving member 15 and the driving efficiency of the baking tray 12, the rotation angle α formed by the rotation of the abutment block 133 between two adjacent positioning members 125 is set to 5°≤α≤80°. Among them, the rotation angle α formed by the abutment block 133 rotating between two adjacent positioning members 125 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.

[0090] Please refer to Figure 6 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.

[0091] It is understood that the connecting column 131 connects the multiple abutment 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 abutment 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.

[0092] Please refer to Figure 6 and 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 .

[0093] 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.

[0094] 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.

[0095] 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 facilitating 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.

[0096] 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.

[0097] In one embodiment of the present invention, the connecting column 131, the fixing seat 135 and the abutting block 133 are an integrated structure;

[0098] 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.

[0099] Please refer to Figure 5 In one embodiment of the present invention, the plurality of abutment blocks 133 are all connected to the side circumferential surface of the fixing seat 135, and a second gap is formed between the surfaces of the plurality of abutment blocks 133 and the fixing seat 135 facing away from the connecting column 131 and the surface of the bottom wall of the baking tray 12 facing the accommodating cavity 111.

[0100] As can be understood, the provision of the second gap ensures that the rotating member 13 is not subjected to the compressive force of the baking tray 12, and is only subject to the circumferential resistance of the positioning member 125 during operation. This reduces the resistance encountered by the driving member 15 when driving the rotating member 13, further reducing the possibility of the driving member 15 seizing due to excessive force during startup. This arrangement also reduces the possibility of heat from the heated baking tray 12 being transferred to the driving member 15 via the rotating member 13, thereby enhancing the protection of the driving member 15. A support structure 14 may be provided between the baking tray 12 and the base 11. This support structure 14 abuts against the baking tray 12, such that a second gap exists between the rotating member 13 and the surface of the baking tray 12 facing the bottom wall of the accommodating cavity 111. Specifically, the support structure 14 may abut against the bottom wall 121 of the baking tray 12, or alternatively, against the side wall 123 of the baking tray 12. When the support structure 14 is in contact with and supported on the bottom wall 121 of the pan, the distance between the center of the bottom wall 121 and the periphery of the bottom wall 121 is defined as D1, and the distance between the support structure 14 and the center of the bottom wall 121 is defined as D2, satisfying the condition: 1 / 4≤D2 / D1≤3 / 4, so that the support structure 14 can be relatively close to the center position between the center of the bottom wall 121 and the periphery of the bottom wall 121 of the pan, so as to provide more stable support for the baking pan 12.

[0101] Please refer to Figure 3 、 Figure 4 as well as Figure 14 In one embodiment of the present invention, a supporting protrusion 141 is provided on the bottom wall of the accommodating cavity 111 . The supporting protrusion 141 is formed as a supporting structure 14 . The supporting protrusion 141 is supported against the surface of the bottom wall of the baking tray 12 facing the accommodating cavity 111 .

[0102] 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.

[0103] 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 to the cavity opening of the accommodating cavity 111 .

[0104] It is understood that the cross-sectional area of ​​the support protrusion 141 is smaller at the top and larger at the bottom, which can reduce the contact area between the support protrusion 141 and the baking tray 12 and reduce the friction generated during the rotation process, thereby improving the smoothness of the driving of the baking tray 12. At the same time, it also makes the connection between the support protrusion 141 and the base 11 more stable, ensuring the strength of the connection between the support protrusion 141 and the base 11, thereby improving the supporting effect of the support protrusion 141. Of course, the present application is not limited to this. In other embodiments, the cross-sectional area of ​​the support protrusion 141 in the direction from the bottom wall of the cavity 111 to the cavity opening of the cavity 111 can also be equal.

[0105] 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 .

[0106] 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.

[0107] 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 .

[0108] 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.

[0109] In one embodiment of the present invention, the cross section of the supporting protrusion 141 is circular.

[0110] 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.

[0111] Please refer to Figure 14 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.

[0112] 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.

[0113] 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 .

[0114] 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.

[0115] 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.

[0116] It is understood that the provision of at least two supporting protrusion groups significantly increases the number of supporting protrusions 141, thereby further improving the stability of the support for the baking tray 12. Of course, in other embodiments, only one supporting protrusion group is also possible.

[0117] Please refer to Figure 18 In one embodiment of the present invention, the support structure 14 includes a plurality of rollers 142 , which are rotatably disposed on the base 11 and distributed around the center line of the accommodating cavity 111 . The plurality of rollers 142 are all supported against the baking tray 12 .

[0118] It is understood that by having multiple rollers 142 abut against and support the baking tray 12, rolling friction is generated between the baking tray 12 and the support structure 14. This reduces the friction experienced by the baking tray 12 when rotating relative to the base 11, thereby improving the smoothness of the rotation of the baking tray 12 and reducing wear during rotation, thereby extending the service life of the baking tray 12 and the support structure 14. The multiple rollers 142 can be fixed in such a manner that the support structure 14 further includes a fixed block 143 and a rotating shaft 144, wherein the fixed block 143 and the base 11 cooperate to clamp and fix the rotating shaft 144, and the rollers 142 are sleeved on the rotating shaft 144.

[0119] Please refer to Figure 21 and Figure 22 In one embodiment of the present invention, a plurality of rollers 142 are rotatably embedded in the surface of the base 11 where the cavity 111 is formed.

[0120] It will be appreciated that the multiple 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 multiple rollers 142 allows for a more compact installation on the base 11, reducing space usage. Of course, the present application is not limited to this embodiment. In other embodiments, the multiple 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 multiple rollers 142 at all locations on the baking tray 12, the multiple rollers 142 may be evenly spaced around the centerline of the cavity 111. At this time, multiple rollers 142 abut 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. Multiple rollers 142 can abut against the flange 1233.

[0121] Please refer to Figure 19 and Figure 20 In one embodiment of the present invention, the side wall of the accommodating cavity 111 is recessed near the cavity opening of the accommodating cavity 111 to form an installation step 1111. The installation step 1111 is arranged in a ring shape around the center line of the accommodating cavity 111, and a plurality of rollers 142 are rotatably embedded in the bottom wall of the installation step 1111.

[0122] It can be understood that the setting of the mounting step 1111 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 step 1111 can accommodate and limit a portion of the side wall 123 of the baking tray 12 (which can be the flange 1233 of the side wall 123 of the baking tray 12), thereby helping to further improve the stability of the baking tray 12 during rotation.

[0123] Please refer to Figure 19 and Figure 20 In one embodiment of the present invention, the support structure 14 further includes a rotating ring 145 . The rotating ring 145 is disposed on the mounting step 1111 and surrounds the outer side of the baking tray 12 . The rotating ring abuts against the plurality of rollers 142 and the baking tray 12 .

[0124] It can be understood that the lower end of the rotating ring 145 abuts against the roller 142, and the upper end abuts against the baking tray 12 (which can be the flange 1233 of the side wall 123 of the baking tray 12), so that the baking tray 12 is supported by the surface. This is beneficial to ensure the supporting effect of the baking tray 12 and reduce the possibility of the baking tray 12 tilting and shaking in the up and down directions.

[0125] Please refer to Figure 23 、 Figure 24 as well as Figure 25 In one embodiment of the present invention, the support structure 14 includes a mounting seat 146 and a main ball 147. The mounting seat 146 is arranged on the cavity wall of the accommodating cavity 111. An accommodating cavity 1461 is formed in the mounting seat 146. The accommodating cavity 1461 has a through hole 1463 facing the baking tray 12; the main roller is arranged in the mounting cavity 112 and is partially exposed to the outside of the mounting seat 146 through the through hole 1463 of the accommodating cavity 1461. The main ball 147 exposed on the outside of the mounting seat 146 abuts against the baking tray 12.

[0126] It is understood that the spherical shape of the main ball bearing 147 allows it to rotate 360° in both the horizontal and vertical planes. Therefore, if the baking tray 12 deviates from the predetermined rotation path during rotation, rolling friction may occur between the main ball bearing 147 and the baking tray 12, thereby reducing the resistance exerted by the main ball bearing 147 on the baking tray 12 during the deviation.

[0127] In one embodiment of the present invention, the support structure 14 also includes a plurality of auxiliary balls 148 , which are disposed in the accommodating cavity 1461 and below the main ball 147 . The plurality of auxiliary balls 148 cooperate with the mounting seat 146 to clamp and limit the main ball 147 .

[0128] It is understood that by having multiple auxiliary balls 148 abutting and supporting the main ball 147, the abutment area on the main ball 147 can be increased, thereby facilitating improved stability of the main ball 147 when installed in the accommodating cavity 1461. The diameters of the multiple auxiliary balls 148 are smaller than those of the main ball 147, and the auxiliary balls 148 can abut various areas of the lower spherical surface of the main ball 147.

[0129] Please refer to Figure 7 、 Figure 8 as well as Figure 9 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.

[0130] 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 fixing seat 135 and can reduce friction between the two. At the same time, such an arrangement also makes the side surfaces 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 fan-shaped, the shape of the positioning member 125 can be made relatively regular, thereby facilitating its processing and manufacturing.

[0131] In one embodiment of the present invention, the positioning member 125 and the baking tray 12 are an integral structure.

[0132] 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.

[0133] Please refer to Figure 4 and Figure 5 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 one 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 assembly 10 also includes a driving member 15, which is disposed in the mounting cavity 112 and connected to the connecting column 131 extending into the mounting cavity 112, and the driving member 15 can drive the connecting column 131 to rotate.

[0134] It can be understood that the provision of the mounting cavity 112 provides installation space for the driver 15, which can make the driver 15 and the base 11 more compactly distributed, thereby helping to reduce the overall volume of the base assembly 10. At the same time, the mounting cavity 112 can also provide a certain degree of isolation and protection for the driver 15, reducing the possibility of the driver 15 being exposed to the outside and easily damaged. Of course, this application is not limited to this. When the base 11 does not have a mounting cavity 112, the driver 15 can also be arranged in the accommodating cavity 111. In addition, in order to improve the controllability of the cooking utensil 100, a circuit board 1120 can be provided in the mounting cavity 112. The circuit board 1120 is electrically connected to the driver 15 so that the working state of the driver 15, such as start, pause or speed, can be controlled by the circuit board 1120.

[0135] Please refer to Figure 3 and Figure 4In one embodiment of the present invention, the base assembly 10 further includes a transmission structure 16, which is disposed in the mounting cavity 112. The transmission structure 16 is transmission-connected to the driving member 15 and the connecting column 131, and the driving member 15 drives the connecting column 131 to rotate through the transmission structure 16.

[0136] 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 has the effect of adjusting 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 evenly and effectively heated. Furthermore, this configuration allows drive member 15 to be horizontally staggered from rotating member 13 , reducing the vertical space occupied by both, thereby facilitating a reduction in the overall volume of base 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 post 131 away from abutment block 133 .

[0137] Please refer to Figure 4 、 Figure 10 as well as Figure 11 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 sleeved on the driving member 15; the driven gear 163 is sleeved on the connecting column 131 extending into the installation cavity 112, and the driven gear 163 and the driving gear 161 are meshed.

[0138] 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 efficiency and stability of the driving of the rotating member 13 can be guaranteed, 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 driving wheel, a driven wheel and an inserted belt. In this case, the driving wheel is connected to the driving member 15, the driven wheel is connected to the connecting column 131 extending into the installation cavity 112, and the conveyor belt is sleeved on the driving wheel and the driven wheel. Alternatively, the transmission structure 16 may also include a worm wheel and a worm. The worm wheel is connected to the connecting column 131 extending into the installation cavity 112, and the worm is connected to the driving member 15 and meshes with the worm wheel.

[0139] Please refer to Figure 11 and Figure 12In 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 .

[0140] 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.

[0141] Please refer to Figure 11 In one embodiment of the present invention, the mounting frame 165 is defined as having an upper surface and a lower surface that are arranged 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 transmission gear.

[0142] It can be understood that by locating the driving gear 161 and the driven gear 163 on the upper surface of the mounting bracket 165 and the driving member 15 on the lower surface of the mounting bracket 165, the driven gear 163 and the connecting column 131 can be relatively close together, thereby facilitating their connection. Furthermore, by making the connecting column 131 relatively short, the stability of the installation of the rotating member 13 and the stability of the abutment and driving force of the positioning member 125 can be improved. The output shaft of the driving member 15 passes through the mounting bracket 165 and is plugged and fixed to the driving gear 161.

[0143] Please refer to Figure 11 and Figure 12 In one embodiment of the present invention, a connecting plate 151 is provided on the side circumference of the driving member 15 , a connecting seat 1651 is provided on the side circumference of the mounting frame 165 , and the connecting plate 151 is connected to the connecting seat 1651 .

[0144] It can be understood that the connecting plate 151 provides a mounting position so that a connecting structure can be set on the connecting plate 151 to fix the driving member 15, thereby reducing the possibility that the setting of the connecting structure will affect the structure of the driving member 15 itself. The setting of the connecting seat 1651 facilitates the connection between the connecting structure set on the connecting plate 151 and the mounting bracket 165. Furthermore, in order to improve the stability of the installation of the driving member 15, the connecting seat 1651 can be supported in contact with the connecting plate 151. In order to allow the driving member 15 to be disassembled and repaired when damaged, the connecting plate 151 and the connecting seat 1651 can be detachably connected, specifically, it can be a screw connection, a snap connection or a magnetic fixation.

[0145] Please refer to Figure 11 、 Figure 12 as well as Figure 13 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 .

[0146] It can be understood that the provision of 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. In other embodiments, the driver 15 can also be attached to the lower surface of the mounting bracket 165.

[0147] Please refer to Figure 12 and Figure 13 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 ring-shaped and is arranged around the rotating axis 144 of the driving gear 161. A limiting ring 1655 is protruded from the upper surface of the mounting bracket 165, and the limiting ring 1655 is embedded in the limiting groove 1611.

[0148] 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.

[0149] Please refer to Figure 12 and Figure 13In 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 , and a mounting groove 1657 is recessed on the upper surface of the mounting bracket 165 , in which the mounting post 1631 is rotatably disposed.

[0150] 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.

[0151] Please refer to Figure 12 and Figure 13 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 column 1631 is inserted into the bearing 167 .

[0152] It can be understood that by connecting the mounting post 1631 and the mounting bracket 165 via the bearing 167, there is no need to set up a more complex structure in the mounting groove 1657. The bearing 167 can be directly placed in the mounting groove 1657 and interference fit with the groove sidewall 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, thereby further simplifying the connection structure between the several. 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 groove 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, so that the mounting post 1631 can rotate circumferentially in the mounting groove 1657 while being axially limited.

[0153] Please refer to Figure 12 and Figure 13 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 away from the mounting groove 1657, and the gasket 169 is connected to the mounting column 1631.

[0154] 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 fixing of the mounting post 1631 can be further improved. That is, in addition to the interference fit with the inner ring 1673 to limit the position, the washer 169 is also used to limit the position. Among them, the washer 169 and the mounting post 1631 can be connected by screws to simplify the connection effect and the connection process between the two. 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 from the mounting opening 1658, thereby improving the convenience of installing the washer 169.

[0155] Please refer to Figure 12 and Figure 13 In one embodiment of the present invention, a mounting platform 1633 is protruding from the surface of the driven gear 163 away from the mounting bracket 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.

[0156] 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.

[0157] Please refer to Figure 4 and Figure 10 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 .

[0158] 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.

[0159] Please refer to Figure 5 and Figure 10 In one embodiment of the present invention, a connecting ear 1659 is further provided on the side circumference of the mounting frame 165 , and a fixing column 1123 is protruding from the top wall of the mounting cavity 112 , and the connecting ear 1659 is connected to the fixing column 1123 .

[0160] 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.

[0161] Please refer to Figure 3 and Figure 4 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.

[0162] It can be understood that the lower reflective plate 115 can reflect the heat below the baking tray 12, reducing the heat loss caused by the heat in the accommodating cavity 111 being lost to the outside through the base 11, thereby improving the utilization efficiency of the heat in the accommodating cavity 111, so as to improve the heating efficiency of the cooking appliance 100 for the food. The lower reflective plate 115 can be connected to the base body 114, specifically by being fixed by a snap or screw connection. The position of the lower reflective plate 115 can be located only between the baking tray 12 and the bottom wall of the accommodating cavity 111; of course, it can also be located partially between the baking tray 12 and the bottom wall of the accommodating cavity 111, and partially between the baking tray 12 and the side wall of the accommodating cavity 111 (in this case, the lower reflective plate 115 can be roughly cylindrical and roughly compatible with 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.

[0163] 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 .

[0164] 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.

[0165] Please refer to Figure 3 and Figure 4In one embodiment of the present invention, the base assembly 10 further includes a lower heating element 17 , which is disposed on a wall surface of the lower reflective plate 115 facing the baking tray 12 .

[0166] 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.

[0167] In one embodiment of the present invention, a groove 1151 is formed on the wall surface of the lower reflective plate 115 facing the lower heating element 17. The groove 1151 is arranged around the center line of the accommodating cavity 111 and is located between two adjacent groups of the support protrusion groups. The lower heating element 17 is embedded in the groove 1151.

[0168] 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.

[0169] Please refer to Figure 14 and Figure 14 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 along the direction facing the groove bottom wall of the groove 1151.

[0170] 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.

[0171] Please refer to Figure 15 、 Figure 16 as well as Figure 17 In one embodiment of the present invention, 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.

[0172] 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.

[0173] Please refer to Figure 15 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 .

[0174] It can be understood that the provision of the exposure hole 1731 can reduce the contact area between the first tube segment 1711 of the heating tube 171 and the bracket 173, thereby reducing the degree to which the first tube segment 1711 transfers heat to the lower reflective plate 115 via the bracket 173, thereby improving the utilization rate of the heat generated by the first tube segment 1711. At the same time, the heat generated by the first tube segment 1711 located below the exposure hole 1731 can be effectively transferred to the grilling pan 12 through the exposure hole 1731.

[0175] Please refer to Figure 15 、 Figure 16 as well as Figure 17 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 .

[0176] 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.

[0177] Please refer to Figure 1 、 Figure 2 as well as Figure 3 The present invention further provides a cooking appliance 100, comprising a base assembly 10 and an upper cover assembly 30. The specific structure of the upper cover assembly 30 is similar to that of the aforementioned embodiments. Since the present cooking appliance 100 utilizes all the technical solutions of all the aforementioned embodiments, it at least possesses all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and therefore, a detailed description thereof will not be repeated here. The upper cover assembly 30 is connected to the base 11 of the base assembly 10 and can open or close the opening of the accommodating cavity 111.

[0178] In one embodiment of the present invention, the upper cover assembly 30 includes an upper cover 31 and an upper heating element. The upper cover 31 is connected to the base 11 and can open or cover the cavity opening of the accommodating cavity 111; the upper heating element is arranged on the wall surface of the upper cover 31 facing the bottom wall of the accommodating cavity 111.

[0179] It will be appreciated that the configuration of the upper heating element allows the cooking device 100 to also heat the upper portion of the baking tray 12, thereby heating both the upper and lower portions of the baking tray 12, further improving the uniformity of heating the food within the baking tray 12. The upper heating element may be a light wave tube, enabling it to quickly generate high temperatures and heat, improving heating efficiency for the food without burning it, thereby preserving the food's color. Of course, the upper heating element may also be an electric heating tube. Furthermore, to enhance the ease of use of the cooking device 100, the upper cover 31 may be pivotally connected to a side edge of the base 11 on one side, eliminating the need for relocation after opening the upper cover 31, thereby enhancing ease of use. Of course, the present application is not limited to this. In other embodiments, the upper cover 31 and the base 11 may simply be in a covering and abutting relationship, allowing it to be removed from the base 11.

[0180] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
