[0058] The rotating grills equipped in existing cooking devices such as ovens and steam ovens can meet the needs of users to bake dried fruits and vegetables and barbecue meats. They can bake the food evenly, with more uniform coloring and better baking effects, enriching the diverse needs of users for food.

[0059] However, the rotating grills equipped in existing cooking devices are all manually installed. After inserting the food onto the rotating grill, one end of the rotating grill is aligned with the motor shaft inside the cooking inner cavity, and then force is applied to insert one end of the rotating grill into the card slot of the motor shaft to achieve the connection between the rotating grill and the motor shaft. When the baking is over, the user still needs to manually disassemble the rotating grill from the motor shaft.

[0060] The rotating grill of the existing cooking device needs to be manually connected to and disassembled from the motor shaft, resulting in low loading and unloading efficiency and troublesome operation of the rotating grill. Moreover, during loading and unloading, the food on the rotating grill is easily soiled or damaged, and the user experience is poor.

[0061] In order to solve the technical problem that the existing rotary grill of a cooking device requires manual connection and disconnection of the rotary grill to and from the motor shaft, resulting in low loading and unloading efficiency of the rotary grill, the present application proposes a rotary grill device and a cooking device. The rotary grill device includes a grill rod body, a driving motor, and a transmission telescopic rod assembly. The transmission telescopic rod assembly has an input end and an output end. The input end is connected to the driving motor, and the output end penetrates into the cooking inner container and corresponds coaxially to one end of the grill rod body. The driving motor is configured such that when rotating in the first rotation direction, it drives the transmission telescopic rod assembly to rotate and extend, so that the output end approaches the grill rod body and is coaxially connected to the grill rod body to drive the grill rod body to rotate; when rotating in the second rotation direction, it drives the transmission telescopic rod assembly to rotate and shorten, so that the output end moves away from the grill rod body and disconnects from the grill rod body to stop the rotation of the grill rod body.

[0062] In the rotary grill device of the present application, when the driving motor rotates in the first rotation direction (forward or reverse), it drives the transmission telescopic rod assembly to rotate and extend, so that the output end of the transmission telescopic rod assembly approaches the grill rod body and is coaxially connected to the grill rod body, thereby driving the grill rod body to rotate. When baking is over or baking is not required, by rotating the driving motor in the second rotation direction (reverse or forward), it drives the transmission telescopic rod assembly to rotate and shorten, so that the output end of the transmission telescopic rod assembly moves away from the grill rod body and disconnects from the grill rod body, thereby stopping the rotation of the grill rod body. By using the rotary grill device of the present application, it is not necessary for the user to manually connect and disconnect the rotary grill to and from the motor shaft, thereby improving the installation efficiency of the rotary grill, realizing automatic installation and disconnection of the rotary grill and the motor shaft, reducing the operation steps of the user, avoiding soiling or damaging the ingredients on the rotary grill during installation and disconnection of the rotary grill, and improving the user experience.

[0063] The following specifically describes the technical solutions of the application with reference to the accompanying drawings in specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0064] In an embodiment of the present application, as shown in Figures 1 to 5 an embodiment of the present application provides a rotary grill device, including a grill rod body 100, a driving motor 200, and a transmission telescopic rod assembly 300.

[0065] The grill rod body 100 is used to be placed on a shelf 30 in a cooking inner container 20 of a cooking device 10.

[0066] The driving motor 200 is used to be arranged on the cooking device 10 and is located outside the cooking inner container 20.

[0067] The transmission telescopic rod assembly 300 has an input end and an output end. The input end is connected to the drive motor 200. The output end penetrates into the cooking inner pot 20 and is coaxially corresponding to one end of the grill rod body 100. The output end is used for detachably connecting with the grill rod body 100.

[0068] The drive motor 200 is configured such that when rotating in the first rotation direction, it drives the transmission telescopic rod assembly 300 to rotate and extend, so that the output end approaches the grill rod body 100 and the output end is coaxially connected with the grill rod body 100 to drive the grill rod body 100 to rotate.

[0069] When rotating in the second rotation direction, it drives the transmission telescopic rod assembly 300 to rotate and shorten, so that the output end moves away from the grill rod body 100 and the output end is disconnected from the grill rod body 100, so that the grill rod body 100 stops rotating.

[0070] Refer to Figure 18 As shown, the grill rod body 100 of the embodiment of the present application is used for inserting food ingredients 50. When the grill rod body 100 rotates, it can drive the food ingredients 50 to rotate, thereby realizing uniform baking of the food ingredients 50.

[0071] Refer to Figure 2 As shown, the drive motor 200 is arranged outside the cooking inner pot 20 of the cooking device 10, and the drive motor 200 can achieve forward rotation and reverse rotation.

[0072] Refer to Figure 3 As shown, the transmission telescopic rod assembly 300 is coaxially corresponding to the grill rod body 100, that is, the transmission telescopic rod assembly 300 and the grill rod body 100 are located on the same axis.

[0073] Refer to Figure 5 、 Figure 10 and Figure 12 As shown, the transmission telescopic rod assembly 300 can extend or shorten. The extension or shortening of the transmission telescopic rod assembly 300 is driven by the forward and reverse rotation of the drive motor 200. For example, when the drive motor 200 rotates forward, the drive motor 200 drives the transmission telescopic rod assembly 300 to rotate forward. While the transmission telescopic rod assembly 300 rotates forward, the transmission telescopic rod assembly 300 extends. When the transmission telescopic rod assembly 300 extends, the output end approaches the grill rod body 100, and finally the output end is coaxially connected with the grill rod body 100. After the output end is coaxially connected with the grill rod body 100, when the transmission telescopic rod assembly 300 rotates, it drives the grill rod body 100 to rotate, thereby realizing the rotation of the grill rod body 100.

[0074] Refer to Figure 12 and Figure 13As shown, when the drive motor 200 rotates in reverse, the drive motor 200 drives the transmission telescopic rod assembly 300 to rotate in reverse. While the transmission telescopic rod assembly 300 rotates in reverse, the transmission telescopic rod assembly 300 is shortened, causing the output end to move away from the grill rod body 100, resulting in the disconnection of the output end from the grill rod body 100 and achieving the stop of the rotation of the grill rod body 100.

[0075] The first rotation direction can be forward rotation or reverse rotation. When the first rotation direction is forward rotation, the rotation of the second rotation direction is reverse rotation; when the first rotation direction is reverse rotation, the rotation of the second rotation direction is forward rotation.

[0076] The rotating grill device of the present application rotates the drive motor 200 in the first rotation direction (forward rotation or reverse rotation), drives the transmission telescopic rod assembly 300 to rotate and extend, so that the output end of the transmission telescopic rod assembly 300 approaches the grill rod body 100 and is coaxially connected to the grill rod body 100, thereby driving the grill rod body 100 to rotate. When the baking is over or baking is not required, the drive motor 200 rotates in the second rotation direction (reverse rotation or forward rotation), drives the transmission telescopic rod assembly 300 to rotate and shorten, so that the output end of the transmission telescopic rod assembly 300 moves away from the grill rod body 100 and disconnects from the grill rod body 100, thereby stopping the rotation of the grill rod body 100. By using the rotating grill device of the present application, it is not necessary for the user to manually connect and disassemble the rotating grill to the motor shaft, thereby improving the installation efficiency of the rotating grill, realizing the automatic installation and disassembly of the rotating grill and the motor shaft, reducing the operation steps of the user, avoiding soiling or damaging the food ingredients 50 on the rotating grill during the installation and disassembly of the rotating grill, and improving the user experience.

[0077] In some embodiments, referring to Figure 6 、 Figure 7 and Figure 10 As shown, the transmission telescopic rod assembly 300 includes a driving member, a transmission member and a connecting member 330. The drive motor 200, the driving member, the transmission member and the connecting member 330 are connected in sequence. The drive motor 200 is used to drive the driving member to rotate, and the connecting member 330 is used for detachably connecting to the grill rod body 100.

[0078] The driving member is configured such that when the drive motor 200 rotates in the first rotation direction, it drives the transmission member and the connecting member 330 to axially move from the first position to the second position and rotate the transmission member and the connecting member 330 at the second position, so that the connecting member 330 is connected to the grill rod body 100 and drives the grill rod body 100 to rotate.

[0079] When the drive motor 200 rotates in the second rotation direction, it drives the transmission member and the connecting member 330 to axially move from the second position to the first position and rotate the transmission member and the connecting member 330 at the first position, so that the connecting member 330 is disconnected from the grill rod body 100.

[0080] In this embodiment, the drive motor 200 drives the driving member to rotate, so that the driving member rotates. When the drive motor 200 rotates in the first rotation direction, the drive motor 200 drives the driving member to rotate, so that the driving member drives the transmission member to move from the first position to the second position, that is, the elongation of the transmission telescopic rod assembly 300 is realized.

[0081] When the transmission member is in the first position, it is not connected to the grill rod body 100. When the transmission member is in the second position, it is connected to the grill rod body 100. When the transmission member is connected to the grill rod body 100, since the drive motor 200 drives the driving member and the transmission member to rotate in sequence, the grill rod body 100 is driven to rotate, and thus the rotation of the grill rod body 100 is realized.

[0082] When the drive motor 200 rotates in the second rotation direction, the drive motor 200 drives the driving member to rotate, and the driving member drives the transmission member to move from the second position to the first position through rotation, that is, the shortening of the transmission telescopic rod assembly 300 is realized, so that the connecting member 330 is disconnected from the grill rod body 100, and thus the rotation of the grill rod body 100 stops.

[0083] In other embodiments, referring to Figure 6 、 Figure 7 and Figure 10 as shown, the driving member is the first transmission rotating shaft 310, and the transmission member is the second transmission rotating shaft 320.

[0084] The first transmission rotating shaft 310 is connected to the drive motor 200. The second transmission rotating shaft 320 is sleeved on the first transmission rotating shaft 310. One end of the second transmission rotating shaft 320 away from the first transmission rotating shaft 310 is detachably connected to the grill rod body 100 through a connecting member 330. A slide rail 400 extending spirally along the axial direction of the first transmission rotating shaft 310 is provided on the side wall of the first transmission rotating shaft 310. A slider 500 is provided on the second transmission rotating shaft 320, and the slider 500 is slidably connected in the slide rail 400.

[0085] The slide rail 400 is configured such that when the first transmission rotating shaft 310 is driven by the drive motor 200 to rotate in the first rotation direction, it drives the slider 500 to move in the slide rail 400 in the direction close to the grill rod body 100, so that the second transmission rotating shaft 320 moves from the first position to the second position.

[0086] When the first transmission rotating shaft 310 is driven by the drive motor 200 to rotate in the second rotation direction, it drives the slider 500 to move in the slide rail 400 in the direction away from the grill rod body 100, so that the second transmission rotating shaft 320 moves from the second position to the first position.

[0087] In this embodiment, it should be noted that the first transmission rotating shaft 310 can be a hollow shaft, so that the second transmission rotating shaft 320 can be sleeved inside the first transmission rotating shaft 310. Of course, the second transmission rotating shaft 320 can also be set as a hollow shaft, so that the first transmission rotating shaft 310 can be sleeved inside the second transmission rotating shaft 320. Specifically, referring to Figure 10 , Figure 11 , Figure 12 and Figure 13 as shown, one end of the first transmission rotating shaft 310 is connected to the driving motor 200. An opening is provided on the cooking inner pot 20. The other end of the first transmission rotating shaft 310 penetrates into the opening and is coaxially connected to the second transmission rotating shaft 320 at least partially located inside the cooking inner pot 20. The driving motor 200 drives the first transmission rotating shaft 310 to rotate forward or backward. A slide rail 400 spirally extending along the axial direction of the first transmission rotating shaft 310 is provided on the side wall of the first transmission rotating shaft 310. A slider 500 is provided on the second transmission rotating shaft 320, and the slider 500 is slidably connected inside the slide rail 400. When the slider 500 is slidably connected inside the slide rail 400, one end of the second transmission rotating shaft 320 is sleeved inside the first transmission rotating shaft 310, and the second transmission rotating shaft 320 is coaxial with the first transmission rotating shaft 310. In the initial state, the slider 500 is located at the end of the slide rail 400 away from the second transmission rotating shaft 320, that is, the second transmission rotating shaft 320 is in the first position. When the driving motor 200 drives the first transmission rotating shaft 310 to rotate in the first rotation direction, for example, when the first rotation direction is forward rotation, at this time the first transmission rotating shaft 310 rotates forward, and the slide rail 400 also rotates forward. Since the slider 500 is slidably connected inside the slide rail 400, the slider 500 is driven to rotate forward. When the slider 500 rotates forward, the slider 500 will move inside the slide rail 400 along the extension direction of the slide rail 400. The slider 500 will move to the end of the slide rail 400 close to the second transmission rotating shaft 320, so that the slider 500 drives the second transmission rotating shaft 320 to approach the grill rod body 100 along its own axis, so that the second transmission rotating shaft 320 moves to the second position, and further enables the connecting member 330 provided on the second transmission rotating shaft 320 to be connected to the grill rod body 100.

[0088] When the driving motor 200 drives the first transmission rotating shaft 310 to rotate in the second rotation direction, at this time, the first transmission rotating shaft 310 rotates in the reverse direction, and the slide rail 400 also rotates in the reverse direction. Since the slider 500 is slidably connected within the slide rail 400, it drives the slider 500 to rotate in the reverse direction. When the slider 500 rotates in the reverse direction, the slider 500 will move within the slide rail 400 along the extension direction of the slide rail 400. The slider 500 will move to one end of the slide rail 400 away from the second transmission rotating shaft 320, thereby causing the slider 500 to drive the second transmission rotating shaft 320 to move away from the grill rod body 100 along its own axis, so that the second transmission rotating shaft 320 moves from the second position to the first position, and thus the connecting member 330 provided on the second transmission rotating shaft 320 is disconnected from the grill rod body 100.

[0089] In some embodiments, it further includes a slide rod 600. A through hole 321 is provided on the second transmission rotating shaft 320, and the slide rod 600 is fixed within the through hole 321, and both ends of the slide rod 600 protrude from the side wall of the second transmission rotating shaft 320, so that both ends of the slide rod 600 respectively form sliders 500; two strip-shaped openings spirally extending along the axis of the first transmission rotating shaft 310 are provided on the side wall of the first transmission rotating shaft 310, and the two strip-shaped openings are centrosymmetric about the center of the first transmission rotating shaft 310, and the two strip-shaped openings respectively form the slide rail 400.

[0090] In this embodiment, referring to Figure 10 、 Figure 11 、 Figure 12 and Figure 13 as shown, two strip-shaped openings centrosymmetric about the center of the first transmission rotating shaft 310 are provided on the side wall of the first transmission rotating shaft 310. The strip-shaped openings are the slide rail 400. The extension direction of each strip-shaped opening is the axis of the first transmission rotating shaft 310, and each strip-shaped opening spirally extends on the side wall of the first transmission rotating shaft 310. The slide rod 600 is fixed within the through hole 321 of the second transmission rotating shaft 320, and both ends of the slide rod 600 protruding from the side wall of the second transmission rotating shaft 320 respectively form sliders 500, that is, both ends of the slide rod 600 are slidably connected within the through hole 321. At this time, the second transmission rotating shaft 320 is located within the first transmission rotating shaft 310 and is coaxial with the first transmission rotating shaft 310, that is, at this time, both the upper and lower ends of the slide rod 600 are slidably connected within the strip-shaped opening, and the middle part of the slide rod 600 is fixed within the through hole 321 of the second transmission rotating shaft 320. When the first transmission rotating shaft 310 rotates, the strip-shaped opening will drive both the upper and lower ends of the slide rod 600 to move in the extension direction of the strip-shaped opening, thereby driving the second transmission rotating shaft 320 to move along its own axis through the slide rod 600. Because the second transmission rotating shaft 320 is coaxially corresponding to the grill rod body 100, the coaxial connection and disconnection of the connecting member 330 provided on the second transmission rotating shaft 320 and the grill rod body 100 are realized, so as to realize the transmission connection and disconnection between the grill rod body 100 and the driving motor 200.

[0091] In one embodiment, referring to Figure 7 , Figure 8 , Figure 9 , Figure 14 and Figure 15 as shown, the connecting member 330 is an elastic buckle. The elastic buckle includes an elastic ring 331 and at least one elastic tooth 332. The elastic ring 331 is coaxially arranged at one end of the second transmission rotating shaft 320 away from the first transmission rotating shaft 310, and each elastic tooth 332 is arranged on the inner circumferential wall of the elastic ring 331; the elastic ring 331 is configured to, when the second transmission rotating shaft 320 moves from the first position to the second position, clamp the grill rod body 100 in the elastic ring 331 through the elastic teeth 332; when the second transmission rotating shaft 320 moves from the second position to the first position, it separates from the grill rod body 100.

[0092] In this embodiment, the elastic ring 331 and the elastic teeth 332 are elastic, and the distance between two symmetric elastic teeth 332 is less than the diameter of the grill rod body 100. Specifically, the difference is 0.5 mm to 1 mm. When the grill rod body 100 penetrates into the elastic ring 331, the elastic teeth 332 will abut against the grill rod body 100, so that the elastic teeth 332 clamp the grill rod body 100 in the elastic ring 331.

[0093] In one embodiment, referring to Figure 7 , Figure 10 , Figure 11 , Figure 12 and Figure 13 as shown, an installation groove 322 is provided on the end face of the second transmission rotating shaft 320 away from the first transmission rotating shaft 310, and the elastic ring 331 is fixed in the installation groove 322.

[0094] In this embodiment, because the elastic ring 331 is elastic and can be stretched, the elastic ring 331 can be snapped into the installation groove 322. The installation groove 322 is a circular groove matching the elastic ring 331, and the outer circumferential wall of the elastic ring 331 abuts against the circular side wall of the circular groove. At this time, the elastic ring 331 is coaxial with the second transmission rotating shaft 320.

[0095] In other possible embodiments, referring to Figure 6 and Figure 16 as shown, it further includes a bushing 700. The bushing 700 is arranged between the outer wall of the cooking inner pot 20 and the driving motor 200, and the first transmission rotating shaft 310 is sleeved inside the bushing 700 to position the first transmission rotating shaft 310.

[0096] In this embodiment, the bushing 700 plays a role in limiting and fixing the first transmission rotating shaft 310, and the bushing 700 abuts between the outer wall of the cooking inner pot 20 and the driving motor 200.

[0097] Meanwhile, when the cooking device 10 has a microwave system 40, the microwave system 40 includes a magnetron, a waveguide, a stirring motor, an antenna, a frequency conversion board, a filter board, etc. That is, there is microwave in the cooking inner container 20 of the cooking device 10. Since the first transmission rotating shaft 310 penetrates at least partially into the opening of the cooking inner container 20, the microwave will leak from the periphery of the first transmission rotating shaft 310 and the opening. In this embodiment, by sleeving the first transmission rotating shaft 310 on the shaft sleeve 700, the shaft sleeve 700 can prevent the microwave from leaking from the periphery of the first transmission rotating shaft 310 and the opening.

[0098] In another possible embodiment, referring to Figure 5 、 Figure 19 and Figure 20 as shown, it further includes a first metal mesh 800 and a second metal mesh 900. The first metal mesh 800 is disposed between the shaft sleeve 700 and the drive motor 200, and two surfaces of the first metal mesh 800 are respectively in contact with the shaft sleeve 700 and the drive motor 200. A first through hole 810 for the motor shaft of the drive motor 200 to pass through is provided on the first metal mesh 800; the second metal mesh 900 is disposed between the shaft sleeve 700 and the outer wall of the cooking inner container 20, and two surfaces of the second metal mesh 900 are respectively in contact with the shaft sleeve 700 and the outer wall of the cooking inner container 20. A second through hole 910 for the first transmission rotating shaft 310 to pass through is provided on the second metal mesh 900.

[0099] In this embodiment, the first metal mesh 800 and the second metal mesh 900 can be copper meshes. Since the surface of the first metal mesh 800 is in contact with the shaft sleeve 700, when the cooking device 10 has a microwave system 40, the first metal mesh 800 can prevent the microwave from leaking from the gap between the shaft sleeve 700 and the drive motor 200.

[0100] Since two surfaces of the second metal mesh 900 are respectively in contact with the shaft sleeve 700 and the outer wall of the cooking inner container 20, when the cooking device 10 has a microwave system 40, the first metal mesh 800 can prevent the microwave from leaking from the gap between the shaft sleeve 700 and the outer wall of the cooking inner container 20.

[0101] That is, the first metal mesh 800 and the second metal mesh 900 of this embodiment can prevent microwave leakage caused by installing the rotary grill device in the cooking inner container 20, and play a role in shielding the microwave at the periphery of the first transmission rotating shaft 310 and the corresponding opening position of the cooking inner container 20, preventing the microwave from leaking from the periphery and the opening of the first transmission rotating shaft 310, and solving the technical problem that the existing cooking device 10 with microwave function cannot install a rotary grill. That is, the rotary grill device of this embodiment can be applied to a microwave and grill integrated machine.

[0102] Further, the side of the first metal mesh 800 away from the bushing 700 is connected to the motor bracket of the driving motor 200.

[0103] By adopting the above technical solution, the first metal mesh 800 fills the gap between the bushing 700 and the driving motor 200, thereby further avoiding the leakage of microwaves from the gap between the bushing 700 and the driving motor 200.

[0104] In some embodiments, referring to Figure 6 and Figure 16 As shown, the first through hole 810 abuts against the outer wall of the first transmission rotating shaft 310, and the second through hole 910 abuts against the outer wall of the first transmission rotating shaft 310.

[0105] In this embodiment, by the first through hole 810 abutting against the outer wall of the first transmission rotating shaft 310 and the second through hole 910 abutting against the outer wall of the first transmission rotating shaft 310, the leakage of microwaves from the circumferential side wall of the first transmission rotating shaft 310 can be further prevented.

[0106] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a second aspect of the embodiments of the present application provides a cooking device, including a cooking inner container 20, on which shelves 30 are provided on opposite side walls in the cooking inner container 20, and further including the rotary grill device of any of the above embodiments, and the rotary grill device is provided on the cooking device.

[0107] The rotary grill device of the embodiments of the present application is provided on the cooking device 10 of the embodiments of the present application. The rotary grill device includes a grill rod body 100, a driving motor 200, and a transmission telescopic rod assembly 300; the transmission telescopic rod assembly 300 has an input end and an output end, the input end is connected to the driving motor 200, and the output end penetrates into the cooking inner container 20 and is coaxially corresponding to one end of the grill rod body 100. The driving motor 200 is configured to drive the transmission telescopic rod assembly 300 to rotate and extend when rotating in the first rotation direction, so that the output end is coaxially connected to the grill rod body 100; when rotating in the second rotation direction, drive the transmission telescopic rod assembly 300 to rotate and shorten, so that the output end is disconnected from the grill rod body 100.

[0108] The cooking device 10 of the present application rotates in a first rotation direction (forward or reverse) through the driving motor 200, drives the transmission telescopic rod assembly 300 to rotate and extend, so that the output end of the transmission telescopic rod assembly 300 approaches the grill rod body 100 and is coaxially connected to the grill rod body 100, thereby driving the grill rod body 100 to rotate. When baking is completed or baking is not required, the driving motor 200 rotates in a second rotation direction (reverse or forward), drives the transmission telescopic rod assembly 300 to rotate and shorten, so that the output end of the transmission telescopic rod assembly 300 moves away from the grill rod body 100 and disconnects from the grill rod body 100, thereby stopping the rotation of the grill rod body 100. By using the rotary grill device of the present application, it is not necessary for the user to manually connect and disassemble the rotary grill to the motor shaft, thereby improving the installation efficiency of the rotary grill, realizing the automatic installation and disassembly of the rotary grill and the motor shaft, reducing the operation steps of the user, avoiding soiling or damaging the food ingredients 50 on the rotary grill during the installation and disassembly of the rotary grill, and improving the user experience.

[0109] It should be noted that the cooking device 10 can be a cooking device in an oven, a steam oven, a microwave oven, a microwave grill integrated machine, an integrated stove, etc.

[0110] In some embodiments, referring to Figure 17 and Figure 18 as shown, a limiting portion 32 is provided on one of the shelves 30, and a mating portion 110 is provided on the grill rod body 100 of the rotary grill device. The limiting portion 32 and the mating portion 110 are in concave-convex fit to limit the axial movement of the grill rod body 100 along its own axis.

[0111] In this embodiment, by providing the limiting portion 32 on the rib 31 of the shelf 30, the limiting portion 32 can be in the shape of a groove, that is, the limiting portion 32 of the rib 31 forms a groove shape, and the mating portion 110 can be in the shape of an annular limiting groove. After the mating portion 110 is placed on the rib 31 at the limiting portion 32, the limiting portion 32 and the mating portion 110 are in concave-convex fit, and the limiting portion 32 plays a limiting role on the mating portion 110. The limiting portion 32 restricts the mating portion 110 from moving along the extending direction of the rib 31 on the rib 31, that is, the mating portion 110 cannot move back and forth, and further restricts the grill rod body 100 from moving back and forth; and when the mating portion 110 is placed on the rib 31, the mating portion 110 can restrict the axial movement of the grill rod body 100 along its own axis, that is, restrict the grill rod body 100 from moving left and right. At this time, the grill rod body 100 can rotate in place on the rib 31 through the mating portion 110.

[0112] In other embodiments, the shelf 30 provided with the limiting portion 32 is close to the transmission telescopic rod assembly 300 of the rotary grill device.

[0113] In this embodiment, the shelf 30 near the drive telescopic rod assembly 300 has a limiting portion 32, and the shelf 30 far from the drive telescopic rod assembly 300 does not have the limiting portion 32. Thus, the friction force on the grill rod body 100 can be minimized as much as possible, and the noise generated when the grill rod body 100 rotates is reduced.
