[0049] Embodiment one

[0050] As Figure 1 And Figure 2As shown, the embodiment provides a roasting rod assembly 10 and a cooking equipment using the roasting rod assembly 10, wherein the roasting rod assembly 10 is used to support and drive food to rotate during food roasting.

[0051] Specifically, the cooking equipment includes a body, a door and a roasting module, wherein the body includes an inner container 20 with a cooking cavity and a casing sleeved outside the inner container 20; the door is movably installed on the front side of the body to open or close the door; the roasting module is used to heat and roast food.

[0052] The roasting rod assembly 10 includes a bracket assembly 4, a driving motor 1 and a roasting rod 2. The bracket assembly 4 has a shaft sleeve 41 with two ends penetrating through, the motor housing 121 of the driving motor 1 is installed on the bracket assembly 4 and the output shaft 11 can rotatably penetrate through the shaft sleeve 41; the first end of the roasting rod 2 is coaxially connected with the output shaft 11 to rotate with the output shaft 11; the sealing sleeve 3 is sleeved between the output shaft 11 and the shaft sleeve 41, and the sealing sleeve 3 and the shaft sleeve 41 are provided with a rotation limiting structure to limit the rotation of the sealing sleeve 3 relative to the bearing.

[0053] The inner container 20 has a first side wall 201 and a second side wall 202 arranged oppositely, and the first side wall 201 is provided with an assembly hole. When the roasting rod assembly 10 is installed on the inner container 20, the bracket assembly 4 and the motor body 12 of the driving motor 1 are located outside the first side wall 201, and the bracket assembly 4 is installed on the inner container 20, the output shaft 11 penetrates through the assembly hole to extend into the cooking cavity through the assembly hole; the second end of the roasting rod 2 is rotatably constrained to the second side wall 202, so that the roasting rod 2 is driven to rotate by the driving motor 1; the sealing sleeve 3 is at least partially located between the hole wall of the assembly hole and the output shaft 11 to seal the gap between the hole wall of the assembly hole and the output shaft 11.

[0054] The roasting rod assembly 10 and the cooking equipment provided by the embodiment have the following advantages. The first end of the roasting rod 2 is coaxially connected to the output shaft 11 of the driving motor 1, so that the driving motor 1 can drive the roasting rod 2 to rotate during cooking, so as to drive the food on the roasting rod 2 to rotate, thereby improving the uniformity of the food in the roasting process, improving the cooking taste and the cooking experience. The sealing sleeve 3 is arranged between the shaft sleeve 41 and the output shaft 11, and the sealing sleeve 3 blocks the gap between the hole wall of the assembly hole and the outer side wall of the output shaft 11, so that the hot air in the cooking cavity cannot flow out of the outer side of the first side wall 201 through the assembly hole, thereby reducing the heat loss in the cooking cavity and reducing the influence of the hot air on the driving motor 1 and the electrical devices between the inner container 20 and the shell, improving the use safety and reliability of the roasting rod assembly 10 and the cooking equipment. The rotation-stopping structure is arranged between the sealing sleeve 3 and the shaft sleeve 41 to limit the rotation of the sealing sleeve 3 relative to the shaft sleeve 41, so that the sealing sleeve 3 does not rotate with the output shaft 11 when the output shaft 11 rotates, thereby reducing the probability of displacement of the sealing sleeve 3 due to movement with the output shaft 11 and the resulting sealing problem, improving the sealing reliability of the sealing sleeve 3 to the assembly hole, and thereby improving the use reliability of the roasting rod assembly 10 and the cooking equipment.

[0055] It should be noted that in the embodiment, the cooking equipment further comprises a steam cooking module for providing steam into the cooking cavity to steam cook the food in the cooking cavity, so that the cooking equipment not only has a roasting cooking mode but also has a steam cooking mode, thereby improving the cooking mode diversity of the cooking equipment and improving the use experience of the cooking equipment. In other embodiments, the cooking equipment can only have a roasting cooking mode.

[0056] In the embodiment, the structures of the machine body, the machine door, the steam cooking module and the roasting cooking module can be arranged according to the prior art, which is not the focus of the present application. The present embodiment only limits and describes the machine body structure of the roasting rod assembly 10.

[0057] As shown in Figures 2 to 9 To improve the convenience of the rotation-stopping structure, the rotation-stopping structure comprises a rotation-stopping groove 311 and a rotation-stopping protrusion 411 that cooperate with each other. One of the rotation-stopping protrusion 411 and the rotation-stopping groove 311 is arranged on the outer side wall of the sealing sleeve 3, and the other is arranged on the inner side wall of the shaft sleeve 41. The rotation-stopping groove 311 and the rotation-stopping protrusion 411 both extend along the axial direction of the output shaft 11, and the rotation-stopping protrusion 411 is inserted into the rotation-stopping groove 311. In this way, the rotation-stopping groove 311 and the rotation-stopping protrusion 411 cooperate to limit the mutual movement of the two in the circumferential direction of the output shaft 11. At the same time, the structure of the rotation-stopping groove 311 and the rotation-stopping protrusion 411 is simple and easy to implement, which is conducive to reducing the processing cost of the roasting rod assembly 10.

[0058] In the embodiment, the rotation-stopping groove 311 is arranged on the outer sidewall of the sealing sleeve 3, and the rotation-stopping protrusion 411 is arranged on the inner sidewall of the shaft sleeve 41, so as to reduce the processing difficulty of the sealing sleeve 3, thereby reducing the processing cost of the baking rod assembly 10. The rotation-stopping groove 311 and the rotation-stopping protrusion 411 have the same cross-sectional shape, so as to avoid the relative movement between the rotation-stopping groove 311 and the rotation-stopping protrusion 411 due to the gap in the circumferential direction of the output shaft 11, and ensure the rotation-stopping effect of the rotation-stopping groove 311 and the rotation-stopping protrusion 411.

[0059] Further, the rotation-stopping groove 311 penetrates the sealing sleeve 3 along the circumferential direction of the sealing sleeve 3, so that the sealing sleeve 3 can be inserted into the shaft sleeve 41 from any end of the shaft sleeve 41, thereby reducing the assembly difficulty of the shaft sleeve 41 and the sealing sleeve 3, and improving the assembly efficiency of the baking rod assembly 10. In other embodiments, the rotation-stopping groove 311 can also penetrate one end of the sealing sleeve 3.

[0060] The cross section of the rotation-stopping groove 311 is in a trapezoidal structure, the small end of the trapezoidal structure forms the groove bottom of the rotation-stopping groove 311, so as to facilitate the guidance of the insertion of the rotation-stopping protrusion 411 into the rotation-stopping groove 311, and facilitate the processing and forming of the rotation-stopping protrusion 411 and the rotation-stopping groove 311. The groove depth of the rotation-stopping groove 311 is preferably 0.5mm-2mm, so as to avoid the problem that the matching depth of the rotation-stopping groove 311 and the rotation-stopping protrusion 411 in the radial direction of the sealing sleeve 3 is too small, the rotation-stopping protrusion 411 is easily pulled out of the rotation-stopping groove 311, and the problem that the rotation-stopping groove 311 is too deep, the wall thickness requirement of the sealing sleeve 3 is increased, and the cost is increased.

[0061] The rotation-stopping grooves 311 are arranged in plurality and spaced apart in the axial direction of the output shaft 11, and the rotation-stopping grooves 311 and the rotation-stopping protrusions 411 are arranged in one-to-one correspondence, so as to increase the rotation-stopping effect. The number of the rotation-stopping grooves 311 is preferably 3-6. In other embodiments, the rotation-stopping groove 311 can also be arranged in only one.

[0062] In order to further improve the setting stability of the sealing sleeve 3, the first end of the sealing sleeve 3 close to the motor body 12 abuts against the end face of the motor body 12, so as to limit the movement of the sealing sleeve 3 in the direction away from the baking rod 2, thereby limiting the sealing sleeve 3 from being pulled out of the assembly hole, and further ensuring the sealing effect of the sealing sleeve 3 on the gap between the hole wall of the assembly hole and the output shaft 11.

[0063] In the embodiment, the motor body 12 comprises a motor shell 121, the motor shell 121 is provided with a boss portion 123 protruding in the direction towards the roasting rod 2, the output shaft 11 is rotatably penetrated through the boss portion 123, the sealing sleeve 3 is provided with a positioning groove 313 at one end close to the motor body 12, the boss portion 123 is inserted into the positioning groove 313; the end face of the boss portion 123 abuts against the groove bottom of the positioning groove 313; and / or the end face of the sealing sleeve 3 abuts against the end face of the motor body 12 which is not provided with the boss portion 123. By arranging the boss portion 123 and the positioning groove 313, the assembly and positioning between the sealing sleeve 3 and the motor body 12 are facilitated.

[0064] In the embodiment, one end of the sealing sleeve 3 close to the roasting rod 2 abuts against the inner container 20, so that the two ends of the sealing sleeve 3 in the circumferential axial direction are limited, which effectively prevents the sealing sleeve 3 from moving in the axial direction of the output shaft 11, further improves the setting stability and reliability of the sealing sleeve 3, and better guarantees the sealing effect.

[0065] The first side wall 201 is provided with a convex ring portion 203 protruding in the direction towards the motor shell 121, and the inner hole of the convex ring portion 203 forms an assembly hole. The arrangement of the convex ring portion 203 can increase the depth of the assembly hole, so as to increase the matching length between the sealing sleeve 3 and the hole wall of the assembly hole, and guarantee the sealing effect.

[0066] In the embodiment, the one end of the sealing sleeve 3 close to the roasting rod 2 is provided with an annular groove 312, and the convex ring portion 203 is inserted into the annular groove 312 and abuts against the groove bottom of the annular groove 312, so that the assembly stability and reliability of the sealing sleeve 3 on the inner container 20 can be better guaranteed, and the matching tightness of the sealing sleeve 3 and the inner container 20 is improved. The convex ring portion 203 is in interference fit with the annular groove 312.

[0067] In order to guarantee the sealing effect of the sealing sleeve 3 while reducing the friction between the sealing sleeve 3 and the output shaft 11, in the embodiment, the sealing sleeve 3 comprises a main sleeve portion 31, one end of the main sleeve portion 31 is inserted between the hole wall of the assembly hole and the output shaft 11, the other end abuts against the motor body 12, and a rotation stopping structure is arranged between the main sleeve portion 31 and the shaft sleeve 41. The inner wall of the main sleeve portion 31 is provided with an inner sealing ring portion 32, and a plurality of inner sealing ring portions 32 are arranged in the axial direction of the sealing sleeve 3. By arranging the inner sealing ring portion 32, when the output shaft 11 rotates, only the inner sealing ring portion 32 contacts the output shaft 11, so as to reduce the contact area between the sealing sleeve 3 and the output shaft 11, and further reduce the friction therebetween; at the same time, since the size of the inner sealing ring portion 32 is relatively small, the gap between the output shaft 11 and the inner wall of the sealing sleeve 3 can be sealed by abutting against the outer side wall of the output shaft 11, so as to guarantee the sealing effect.

[0068] The inner sealing ring part 32 is preferably in the shape of a circular arc in cross section to ensure a sealing fit with the corresponding output shaft 11 or assembly hole wall.

[0069] In the embodiment, the bracket assembly 4 further comprises a mounting bracket 42, which is separate from the shaft sleeve 41 and is mounted on the outer side of the first side wall 201 and has a mounting through hole. The motor body 12 is mounted on the side of the mounting bracket 42 away from the roasting rod 2, and the first end of the shaft sleeve 41 away from the roasting rod 2 is inserted into the mounting through hole and abuts against the end face of the motor body 12. By separating the shaft sleeve 41 and the mounting bracket 42, the machining of the shaft sleeve 41 is facilitated, and the requirements for the structure and machining precision of the mounting bracket 42 are reduced, thereby reducing the machining and design costs of the bracket assembly 4.

[0070] In other embodiments, the bracket assembly 4 comprises a mounting plate part 421 opposite and spaced apart from the first side wall 201, and the mounting plate part 421 is integrally formed or welded with the shaft sleeve 41.

[0071] Further, the mounting bracket 42 comprises a mounting plate part 421 opposite and spaced apart from the first side wall 201, and the mounting plate part 421 protrudes in the direction towards the first side wall 201 with an extension sleeve part 423. The inner hole of the extension sleeve part 423 forms a mounting through hole, and the mounting through hole penetrates through the mounting plate part 421. Thus, the hole length of the mounting through hole can be increased, thereby increasing the fitting length between the shaft sleeve 41 and the extension sleeve part 423, ensuring the relative position reliability between the shaft sleeve 41 and the mounting bracket 42, and improving the assembly reliability of the roasting rod assembly 10.

[0072] The side of the mounting plate part 421 towards the first side wall 201 is connected with a connecting arm part 422, and the connecting arm part 422 is connected with the first side wall 201 to improve the connection convenience. Thus, the mounting stability and reliability of the mounting bracket 42 on the first side wall 201 can be improved. Preferably, the opposite sides of the mounting plate part 421 are both provided with the connecting arm part 422 to improve the mounting stability and reliability of the mounting bracket 42 with the first side wall 201.

[0073] Further, the connecting arm part 422 comprises a vertical extension plate part 4221 and a fixed plate part 4222, the fixed plate part 4222 is attached to the first side wall 201, and the extension plate part 4221 is connected between the mounting plate part 421 and the fixed plate part 4222. The fixed plate part 4222 is preferably connected with the first side wall 201 by screws to ensure the setting stability and reliability of the mounting bracket 42. The fixed plate part 4222 is located on the side of the extension plate part 4221 away from the other extension plate part 4221 to avoid interference between the fixed plate part 4222 and the sealing sleeve 3, the shaft sleeve 41 and other structures, and improve the connection convenience of the fixed plate part 4222 and the first side wall 201.

[0074] In the embodiment, the cooking device also has a microwave cooking function. To prevent microwaves from leaking outwards through the assembly hole, the shaft sleeve 41 is made of metal material, and the end face of the motor shell 121 is provided with a metal structure 122. The end face of the shaft sleeve 41 away from the first side wall 201 abuts against the metal structure 122. Thus, the microwaves leaking out of the assembly hole can be limited between the metal sleeve and the output shaft 11 by the abutment of the two ends of the shaft sleeve 41 against the first side wall 201 and the metal structure 122 respectively, and the microwaves are prevented from further overflowing outwards through the metal sleeve, thereby improving the use safety and reliability of the cooking device.

[0075] In the embodiment, the roasting rod 2 is connected with the output shaft 11 through the connecting sleeve 5. The connecting sleeve 5 is located inside the inner container 20 and coaxially arranged with the output shaft 11, so as to ensure the coaxial rotation of the output shaft 11, the connecting sleeve 5 and the roasting rod 2. The first end of the roasting rod 2 is plug-in connected with the connecting sleeve 5, and / or the connecting sleeve 5 is plug-in connected with the output shaft 11, so as to facilitate the separation of the roasting rod 2 and the output shaft 11, thereby facilitating the installation and disassembly of the roasting rod 2 in the inner container 20.

The outer diameter of the anti-rotation sleeve part 315 is greater than the inner diameter of the convex ring part 203, so as to limit the insertion of the anti-rotation sleeve part 315 into the convex ring part 203.

[0079] By arranging the sealing main part 314 and the anti-rotation sleeve part 315, the size of the sealing main part 314 can be reduced while ensuring that the sealing sleeve 3 locally has sufficient size to cooperate with the shaft sleeve 41, thereby reducing the size of the assembly hole. At the same time, the arrangement of the anti-rotation sleeve part 315 and the sealing main part 314 facilitates the limitation of the overall sealing sleeve 3 from passing through the assembly, and the cooperation between the end face of the anti-rotation sleeve part 315 and the end face of the convex ring part 203 can limit the movement of the sealing sleeve 3 in the direction towards the roasting rod 2, thereby further improving the setting stability and reliability of the roasting rod assembly 10.

[0080] In the embodiment, the outer side wall of the sealing sleeve 3 is provided with an outer sealing ring part 33, which abuts against the hole wall of the assembly hole, so that the hole wall of the assembly hole can be pressed by the deformation of the outer sealing ring part 33, thereby ensuring the close contact between the sealing sleeve 3 and the hole wall of the assembly hole, and further improving the sealing effect.

[0081] The cross sections of the inner sealing ring part 32 and the outer sealing ring part 33 are preferably circular arcs, so as to ensure the sealing cooperation effect on the corresponding output shaft 11 or the hole wall of the assembly hole.
