[0046] Embodiment one

[0047] The embodiment provides a cooking equipment with microwave cooking function and baking function, so as to improve the flexible selection of the cooking equipment for various cooking modes, and improve the use reliability and use experience of the cooking equipment.

[0048] As Figure 1 And Figure 2As shown, the cooking equipment provided by the embodiment includes a body, a door, a microwave cooking module and a baking module. The body has an inner container 20 and a shell arranged outside the inner container 20. The inner container 20 has a cooking cavity with an open front side. The door is movably mounted on the outside of the body to selectively open or close the cooking cavity. The microwave cooking module is used for microwave cooking food in the inner container 20. The baking module is used for baking food in the cooking cavity.

[0049] To improve the convenience of food baking, the inner container 20 has a first side wall 201 and a second side wall 202 arranged opposite to each other. The first side wall 201 is provided with an assembly hole 205. The cooking equipment further includes a rotating baking assembly 10. The rotating baking assembly 10 includes a driving motor 1 and a rotating baking piece 2. The motor shell 12 of the driving motor 1 is mounted on the outside of the first side wall 201, and the output shaft 11 of the driving motor 1 is rotatably arranged through the assembly hole 205. The rotating baking piece 2 is arranged in the inner container 20 and has at least a first end portion adjacent to the first side wall 201 and a second end portion adjacent to the second side wall 202. The first end portion is coaxially connected with the output shaft 11 to rotate synchronously with the output shaft 11. The second end portion is rotatably constrained to the second side wall 202.

[0050] By arranging the driving motor 1 and the rotating baking piece 2, when the food is baked by the baking module, the food is placed on the rotating baking piece 2, and the driving motor 1 drives the rotating baking piece 2 to rotate, so that the food is driven to rotate by the rotating baking piece 2, thereby improving the uniformity of the heating of the food in the cooking cavity, and further improving the taste of the baked food and the use experience of the cooking equipment.

[0051] In the embodiment, the cooking equipment further includes a leakage prevention structure made of metal and arranged around the output shaft 11 to be located on the microwave overflow path. The leakage prevention structure has a first sealing ring surface and a second sealing ring surface arranged opposite to each other in the axial direction of the output shaft 11. The first sealing ring surface is attached to the inner container 20, and the second sealing ring surface is attached to the end face of the motor shell 12.

[0052] The cooking equipment provided by the embodiment has the first sealing ring surface of the leakage prevention structure attached to the inner container 20, so that no gap is formed between the leakage prevention structure and the inner container 20 for microwave leakage. Meanwhile, the second sealing ring surface is attached to the end face of the motor shell 12, so that no gap is formed between the leakage prevention structure and the motor shell 12 for microwave leakage. That is, the gap between the inner container 20 and the end face of the motor shell 12 is blocked by the leakage prevention structure. Thus, the microwave is blocked in the annular space formed by the output shaft 11 and the leakage prevention structure, and cannot continue to overflow outward through the leakage prevention structure, thereby achieving the leakage prevention effect of the microwave and improving the use safety and reliability of the cooking equipment. Meanwhile, the leakage prevention structure is arranged around the output shaft 11 and abuts against the end faces of the inner container 20 and the motor shell 12 at both ends, which is simple in structure and easy to implement.

[0053] In this embodiment, the anti-leakage structure is located on the outside of the first sidewall 201 to reduce the difficulty of setting the anti-leakage structure and to avoid the microwave arcing problem caused by the poor fit between the anti-leakage structure and the inner liner 20.

[0054] Furthermore, the leak-proof structure extends axially along the output shaft 11, and the first sealing ring surface fits against the outer surface of the first sidewall 201, so as to further improve the convenience of the leak-proof structure and the inner liner 20.

[0055] like Figure 3 As shown, in this embodiment, the anti-leakage structure includes a metal sleeve 3 and a first metal sheet 4. The metal sleeve 3 is sleeved on the outside of the output shaft 11, and the first end of the metal sleeve 3 facing the first sidewall 201 forms a first sealing ring surface. The first metal sheet 4 is attached to the end face of the motor housing 12, and the second end face of the metal sleeve 3 is attached to the first metal sheet 4. The other end face of the first metal sheet 4 forms a second sealing ring surface. The outer peripheral wall of the metal sleeve 3 and the outer peripheral wall of the first metal sheet 4 together form a sealing peripheral surface.

[0056] By setting the metal sleeve 3, it is beneficial to extend the anti-leakage structure along the output shaft 11 axial direction. This not only achieves microwave anti-leakage, but also increases the distance between the end face of the motor housing 12 and the first side wall 201, thereby facilitating the installation of the drive motor 1 in the inner liner 20 and the installation of the anti-leakage structure. By setting the first metal piece 4, which is sandwiched between the metal sleeve 3 and the end face of the motor housing 12, it is beneficial to reduce the requirements for the processing accuracy and assembly accuracy of the metal sleeve 3, and better ensure the fit between the anti-leakage structure and the end face of the motor housing 12.

[0057] In other embodiments, the anti-sealing structure may consist only of a metal sleeve 3, with its opposite ends forming a first sealing ring surface and a second sealing ring surface, respectively. That is, the metal sleeve 3 directly abuts against the end face of the motor housing 12.

[0058] To further improve the leakage prevention effect, in this embodiment, the first metal sheet 4 is a metal mesh structure with a certain degree of flexibility. It is sandwiched between the end face of the motor housing 12 and the metal sleeve 3, which facilitates the metal sleeve 3 pressing the first metal sheet 4 tightly against the end face of the motor housing 12. This ensures a tight fit between the first metal sheet 4, the metal sleeve 3, and the end face of the motor housing 12, thereby improving the microwave leakage prevention effect. In other embodiments, the first metal sheet 4 can also be a metal plate structure or a metal film structure.

[0059] The first metal sheet 4 extends radially outward of the metal sleeve 3 along the output shaft 11, i.e. the outer diameter of the first metal sheet 4 is greater than the outer diameter of the metal sleeve 3. In this way, the contact area between the metal sleeve 3 and the first metal sheet 4 can be increased, the connection between the metal sleeve 3 and the first metal sheet 4 can be ensured to be gap-free, and the assembly precision requirement of the first metal sheet 4 and the metal sleeve 3 can be reduced. In other embodiments, the outer diameter of the first metal sheet 4 can be equal to or slightly smaller than the outer diameter of the metal sleeve 3.

[0060] Further, the inner diameter of the first metal sheet 4 is greater than the inner diameter of the metal sleeve 3, so as to ensure that the end face of the metal sleeve 3 is in contact with the first metal sheet 4, and the contact reliability and tightness of the two can be ensured.

[0061] Further, the end face of the motor shell 12 is provided with a boss portion 13, the output shaft 11 penetrates through the boss portion 13, and the inner diameter of the first metal sheet 4 is equal to the diameter of the boss portion 13. In this way, the first metal sheet 4 is sleeved on the boss portion 13, the setting stability of the first metal sheet 4 is improved, and the microwave leakage prevention effect is also improved.

[0062] In order to further improve the setting stability of the first metal sheet 4, the end face of the motor shell 12 is provided with a groove 121, and the first metal sheet 4 is accommodated in the groove 121. In this way, the installation and positioning of the first metal sheet 4 on the motor shell 12 can be realized through the groove 121, the installation precision of the first metal sheet 4 can be ensured, and the setting stability of the first metal sheet 4 is improved.

[0063] The first metal sheet 4 is preferably bonded to the bottom of the groove 121, so as to ensure the setting stability of the first metal sheet 4. In other embodiments, the first metal sheet 4 can be connected to the motor shell 12 by means of screws or welding, or the first metal sheet 4 is directly pressed against the end face of the motor shell 12 by the metal sleeve 3.

[0064] In the embodiment, in order to improve the installation convenience of the driving motor 1, the cooking device further comprises a mounting bracket 5, the mounting bracket 5 is mounted outside the first side wall 201, and the motor shell 12 is mounted on the mounting bracket 5.

[0065] Specifically, the cooking device comprises an intermediate side wall 30 which is arranged outside the first side wall 201 in a spaced manner, and the intermediate side wall 30 is provided with an avoiding through hole. The mounting bracket 5 is mounted between the intermediate side wall 30 and the first side wall 201, and the mounting bracket 5 has a mounting plate portion 51 which is provided corresponding to the avoiding through hole and a fixing plate portion 53 which is connected between the mounting plate portion 51 and the outside of the first side wall 201, and the mounting plate portion 51 is provided with a shaft through hole 54. The driving motor 1 is mounted on the side of the mounting plate portion 51 which is away from the first side wall 201, and the output shaft 11 is rotatably penetrated through the shaft through hole 54. In this way, the disassembly and assembly convenience of the driving motor 1 can be improved.

[0066] The sleeve portion 52 is provided on the mounting plate portion 51 in a direction towards the first side wall 201, and an inner hole of the sleeve portion 52 forms an shaft hole 54 through which the output shaft 11 is rotatable. Thus, the installation and positioning of the driving motor 1, the metal sleeve 3 and the mounting bracket 5 can be achieved through cooperation of the metal sleeve 3 and the sleeve portion 52, and the accuracy of the assembly positions of the three is ensured, thereby improving the assembly level precision of the cooking device and better ensuring the installation precision of the anti-leakage structure.

[0067] Further, the first side wall 201 is outwardly convexly provided with a convex ring portion 203, and an assembly hole 205 is extended from the first side wall 201 to an outer side of the convex ring portion 203, thereby being able to increase the axial length of the assembly hole 205 and improve the cooperation reliability of the output shaft 11 and the assembly hole 205. The metal sleeve 3 is sleeved on the convex ring portion 203, thereby being able to better achieve the installation and positioning of the metal sleeve 3 on the first side wall 201 and further improve the installation reliability of the anti-leakage structure.

[0068] In the embodiment, the sealing member 7 is also rotatably sleeved on the output shaft 11 and is in interference fit with the assembly hole 205. The sealing member 7 is provided to seal the gap between the output shaft 11 and the hole wall of the assembly hole 205, thereby preventing the gas in the cooking cavity from leaking outward through the assembly hole 205, facilitating better guarantee of the cooking effect and reducing the influence of hot gas on the electrical components inside the driving motor 1. Meanwhile, the arrangement is also conducive to implementation of the steam cooking mode in the cooking device. It can be understood that, in other embodiments, the sealing member 7 can also not be arranged between the hole wall of the assembly hole 205 and the output shaft 11.

[0069] The sealing member 7 is preferably a sleeve structure extending in the axial direction of the output shaft 11, and a first end of the sealing member 7 is located in the assembly hole 205 and a second end thereof extends to abut against the boss portion 13, so as to better guarantee the sealing effect.
