[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0044] An embodiment of the present application provides a cooking device, which can be an oven, a steam box, a steam - baking integrated machine, a baking - microwave integrated machine, or a steam - baking - microwave integrated machine. In the embodiments of the present application, the cooking device is taken as an example of a steam - baking - microwave integrated machine for illustration.

[0045] Figure 1 It is a schematic structural diagram of a cooking device provided by an embodiment of the present application.

[0046] See Figure 1 As shown, the cooking device 100 may include a housing 110. The housing 110 may have a cooking cavity 111, and the cooking cavity 111 may be used to accommodate food ingredients for heating the food ingredients. Among them, a rotating roasting rod (not shown in the figure) may be provided in the cooking cavity 111, and the food ingredients may be threaded on the rotating roasting rod. The rotation of the rotating roasting rod may drive the food ingredients to rotate together to improve the uniformity of heat reception of the food ingredients.

[0047] For example, the cooking device 100 may further include a driving motor 120. The driving motor 120 may be located outside the housing 110. A motor mounting hole 112 may be provided on the housing 110 of the cooking device 100, and the motor mounting hole 112 may communicate with the cooking cavity 111. The driving shaft 122 of the driving motor 120 may pass through the motor mounting hole 112 and be connected to the rotating roasting rod inside the housing 110 to drive the rotating roasting rod to rotate.

[0048] The cooking appliance 100 may also have a microwave function, so that the cooking appliance 100 can heat the food ingredients by microwave.

[0049] However, in current cooking appliances, the steam generated during the microwave and steaming / baking processes easily leaks out through the gap between the drive shaft and the motor mounting hole of the housing. The steam will affect the working components of the cooking appliance and reduce the service life of the components in the cooking appliance. After the microwave radiates outward from the gap, it will cause harm to the human body, affecting the personal safety of the user, and thus affecting the service life of the cooking appliance and the personal safety of the user.

[0050] To solve the above problems, the embodiments of the present application have improved the cooking appliance 100. By providing a sealing sleeve 130 and a metal isolation sleeve 140 between the drive shaft 122 of the drive motor 120 and the housing 110, the sealing sleeve 130 can provide a seal between the drive shaft 122 and the housing 110. It can effectively reduce or avoid the steam in the cooking cavity 111 from leaking out through the part of the mounting hole of the drive motor 120, improve the protection of other components in the cooking appliance 100, and thus effectively extend the service life of the components in the cooking appliance 100. The metal isolation sleeve 140 and the housing 110 and the drive motor 120 can form a closed metal shielding structure, which can shield the microwave, effectively avoid the microwave from radiating outward from the enclosure between the motor mounting hole 112 and the motor, and prevent the harm caused by microwave radiation to the human body, thereby effectively improving the safety of the cooking appliance 100.

[0051] The following will describe the cooking appliance 100 provided by the embodiments of the present application in detail with reference to the accompanying drawings.

[0052] Figure 2 is an exploded view of a cooking appliance provided by an embodiment of the present application, Figure 3 is a front exploded view of a cooking appliance provided by an embodiment of the present application.

[0053] The embodiments of the present application provide a cooking appliance 100. Referring to Figure 2 and Figure 3 as shown, the cooking appliance 100 may further include a sealing sleeve 130. The sealing sleeve 130 can be sleeved on the drive shaft 122 of the drive motor 120, and the sealing sleeve 130 can be used to provide a seal between the drive shaft 122 and the housing 110. The inner circle of the density sealing sleeve 130 can be in sealed contact with the drive shaft 122 of the drive motor 120, and the outer circle can be in sealed contact with the inner circle of the motor mounting hole 112 on the housing 110.

[0054] For example, the sealing sleeve 130 can be made of elastic materials such as rubber, soft rubber, and silicone rubber. The sealing sleeve 130 can be in a squeezed state between the drive shaft 122 and the housing 110. The squeezed sealing sleeve 130 has a resilience force, which can enable the sealing sleeve 130 to have good sealing contact with the drive shaft 122 and the housing 110, so that the sealing sleeve 130 can provide a better sealing effect between the drive shaft 122 and the housing 110.

[0055] This can effectively reduce or avoid the leakage of steam in the cooking cavity 111 from the part of the mounting hole of the drive motor 120 to the outside, effectively improve the protection of other components in the cooking appliance 100, and thus effectively extend the service life of the components in the cooking appliance 100.

[0056] The cooking appliance 100 may further include a metal isolation sleeve 140. The metal isolation sleeve 140 can be sleeved on the drive shaft 122, and one end of the metal isolation sleeve 140 can be abutted against the housing 110, and the other end can be abutted against the drive motor 120. In this way, a closed metal shielding structure can be formed among the housing 110, the metal isolation sleeve 140, and the drive motor 120 of the cooking appliance 100, which can shield microwaves, effectively avoid the outward radiation of microwaves from the closure between the motor mounting hole 112 and the motor, and prevent microwave radiation from harming the human body, thereby effectively improving the safety of the cooking appliance 100.

[0057] Continue to refer to Figure 3 As shown, the drive motor 120 can include a motor body 121 and a drive shaft 122. The motor body 121 can be connected to the housing 110. The drive shaft 122 can extend into the motor mounting hole 112 and be connected to the rotating roasting rod in the housing 110. One end of the metal isolation sleeve 140 can be abutted against the housing 110, and the other end can be abutted against the motor body 121. So that a closed shielding structure can be formed among the housing 110, the metal isolation sleeve 140, and the motor body 121 to isolate microwaves, thereby effectively avoiding the outward radiation of microwaves.

[0058] Continue to refer to Figure 3 As shown, the cooking appliance 100 may further include a mounting bracket 150. The mounting bracket 150 can be connected to the housing 110, and the drive motor 120 can be mounted on the mounting bracket 150. The motor body 121 of the drive motor 120 can be mounted on the mounting bracket 150, so that the drive motor 120 can be connected to the housing 110 through the cooperation between the motor body 121 and the mounting. This can facilitate the installation and disassembly of the drive motor 120 and is beneficial to improving the reliability and stability of the connection between the drive motor 120 and the housing 110.

[0059] For example, the mounting bracket 150 and the housing 110 can be connected by means such as bolt fasteners or welding. The drive motor 120 and the mounting bracket 150 can be detachably connected by bolt fasteners to facilitate the maintenance and servicing of the drive motor 120.

[0060] Figure 4 The front view cross-sectional view of a cooking appliance provided by an embodiment of the present application Figure 5 is Figure 4 an enlarged view of area A in

[0061] Refer to Figure 4 and Figure 5 As shown, the metal isolation sleeve 140 can be nested on the outer periphery of the sealing sleeve 130, that is, the metal isolation sleeve 140 and the sealing sleeve 130 overlap with each other in the axial direction of the drive shaft 122. The sealing sleeve 130 is located inside the metal isolation sleeve 140, and the sealing sleeve 130 can isolate between the metal isolation sleeve 140 and the cooking cavity 111. The steam in the cooking cavity 111 can be blocked within the sealing sleeve 130, which can effectively reduce or avoid the contact between the steam in the cooking cavity 111 and the metal isolation sleeve 140, and can reduce or avoid the corrosion of the metal isolation sleeve 140 caused by the contact with the steam, which helps to improve the protection of the metal isolation sleeve 140 and extend the service life of the metal isolation sleeve 140.

[0062] Moreover, through the steam isolation protection of the sealing sleeve 130 for the metal isolation sleeve 140, the anti-corrosion performance requirements for the metal isolation sleeve 140 can be reduced, which helps to reduce the material cost of the metal isolation sleeve 140.

[0063] In addition, by overlapping the metal isolation sleeve 140 and the sealing sleeve 130 with each other in the axial direction of the drive shaft 122, the occupied space of the metal isolation sleeve 140 and the sealing sleeve 130 in the axial direction of the drive shaft 122 can be effectively reduced, and the compactness of the installation of the metal isolation sleeve 140 and the sealing sleeve 130 on the drive shaft 122 can be improved. Moreover, the length of the drive shaft 122 can be designed to be shorter, which helps to improve the structural strength and stiffness of the drive shaft 122, thereby enhancing the stability and reliability of the drive of the drive motor 120.

[0064] Continuing to refer to Figure 4 and Figure 5 As shown, the metal isolation sleeve 140 can include a first main body portion 141 and a first elastic ring 142. The first elastic ring 142 can be located between the first main body portion 141 and the housing 110, and the first elastic ring 142 can be in an elastically compressed state. For example, the first elastic ring 142 can be an elastic structural member such as an elastic gasket. The first main body portion 141 can be sleeved on the sealing sleeve 130, and the first main body portion 141 and the housing 110 can be connected by the first elastic ring 142.

[0065] The first elastic ring 142 in elastic compression has a resilience force, which can drive the first elastic ring 142 to deform towards the directions of the first main body portion 141 and the housing 110, so that the first elastic ring 142 can be in closer contact with the first main body portion 141 and the housing 110. This can effectively improve the sealing performance of the contact between the first elastic ring 142 and the first main body portion 141 and the housing 110, enable better sealing performance between the metal isolation sleeve 140 and the housing 110, and thus effectively enhance the microwave shielding effect between the metal isolation sleeve 140 and the housing 110.

[0066] Continue to refer to Figure 5 As shown, the metal isolation sleeve 140 may further include a second elastic ring 143. The second elastic ring 143 may be located between the first main body portion 141 and the drive motor 120, and the second elastic ring 143 may be in an elastic compression state. For example, the second elastic ring 143 may also be an elastic structural member such as an elastic gasket, and the first main body portion 141 and the motor body 121 of the drive motor 120 may be connected through the second elastic ring 143.

[0067] The second elastic ring 143 in elastic compression also has a resilience force, which can drive the second elastic ring 143 to deform towards the directions of the first main body portion 141 and the drive motor 120, so that the second elastic ring 143 can be in closer contact with the first main body portion 141 and the drive motor 120. This can effectively improve the sealing performance of the contact between the second elastic ring 143 and the first main body portion 141 and the drive motor 120, enable better sealing performance between the metal isolation sleeve 140 and the drive motor 120, and thus effectively enhance the microwave shielding effect between the metal isolation sleeve 140 and the drive motor 120, and enhance the overall microwave shielding effect of the metal isolation sleeve 140.

[0068] Continue to refer to Figure 5 As shown, a flanging ring 113 may be provided around the outer periphery of the motor mounting hole 112 (refer to Figure 2 shown), and a part of the sealing sleeve 130 may be located between the flanging ring 113 and the drive shaft 122. For example, a part of the outer periphery of the sealing sleeve 130 may be in sealing contact with the inner wall of the flanging ring 113.

[0069] The inner wall of the flanging ring 113 has a larger size, which can increase the contact area between the sealing sleeve 130 and the housing 110. This can effectively improve the sealing performance between the sealing sleeve 130 and the housing 110, and thus enhance the sealing performance between the drive shaft 122 and the housing 110.

[0070] Moreover, the contact area between the sealing sleeve 130 and the housing 110 is increased, which can also improve the contact stability between the sealing sleeve 130 and the housing 110, effectively reduce or avoid misalignment, disengagement, etc. between the sealing sleeve 130 and the housing 110, and prevent the misalignment of the sealing sleeve 130 from affecting the sealing performance between the sealing sleeve 130 and the housing 110. It can effectively improve the stability and reliability of the cooperation between the sealing sleeve 130 and the housing 110, thereby effectively enhancing the sealing performance between the sealing sleeve 130 and the housing 110.

[0071] Continue to refer to Figure 5 As shown, the sealing sleeve 130 may include a connected second main body portion 131 and a shaft shoulder portion 132. A part of the second main body portion 131 may be located between the flanging ring 113 and the drive shaft 122. The shaft shoulder portion 132 may surround the outer periphery of the second main body portion 131, and the end face of the flanging ring 113 may abut against the shaft shoulder portion 132.

[0072] The second main body portion 131 may provide a seal between the drive shaft 122 and the flanging ring 113 to reduce or avoid steam leakage from the gap between the flanging ring 113 and the drive shaft 122. The shaft shoulder portion 132 abuts against the end of the flanging ring 113, which can provide further sealing between the sealing sleeve 130 and the end of the flanging ring 113. So that the sealing sleeve 130 and the flanging ring 113 can have sealed contact at two places, namely the second main body portion 131 and the shaft shoulder portion 132, to achieve double sealing. This can effectively improve the sealing performance between the sealing sleeve 130 and the flanging ring 113, effectively reduce or avoid steam leakage from between the sealing sleeve 130 and the flanging ring 113, and thus effectively improve the protection of the components in the cooking appliance 100.

[0073] Continue to refer to Figure 5 As shown, the sealing sleeve 130 may further include a first protrusion portion 133. The first protrusion portion 133 may be located on the inner ring of the sealing sleeve 130 and abut against the drive shaft 122. For example, the first protrusion portion 133 may be a closed annular structure, and the first protrusion portion 133 may surround the inner wall of the sealing sleeve 130.

[0074] The first protrusion portion 133 may be in a compressed state. The first protrusion portion 133 in the compressed state has a resilience force, which can drive the first protrusion portion 133 to deform in the direction of the drive shaft 122, so that the contact between the first protrusion portion 133 and the drive shaft 122 can be closer. This can effectively improve the sealing performance of the contact between the first protrusion portion 133 and the drive shaft 122, make the sealing performance between the sealing sleeve 130 and the drive shaft 122 better, and thus effectively enhance the steam isolation effect between the sealing sleeve 130 and the drive shaft 122.

[0075] For example, the inner wall of the sealing sleeve 130 may have a plurality of first protrusions 133. The first protrusions 133 may be spaced apart along the axial direction of the sealing sleeve 130. The plurality of first protrusions 133 may provide a seal between the inner wall of the sealing sleeve 130 and the drive shaft 122, effectively improving the sealing performance between the sealing sleeve 130 and the drive shaft 122 and enhancing the steam isolation effect between the sealing sleeve 130 and the drive shaft 122.

[0076] Continuing to refer to Figure 5 As shown, the sealing sleeve 130 may further include a second protrusion 134. The second protrusion 134 may be located at one end of the sealing sleeve 130 facing the motor body and abuts against the motor body. For example, the second protrusion 134 may also be a closed annular structure, and the second protrusion 134 may surround the end of the sealing sleeve 130 facing the motor body.

[0077] The second protrusion 134 may also be in a compressed state. The second protrusion 134 in the compressed state has a resilience force, and this resilience force can drive the second protrusion 134 to deform in the direction of the motor body, enabling the second protrusion 134 to be in closer contact with the motor body. This can effectively improve the sealing performance of the contact between the second protrusion 134 and the motor body, making the sealing sleeve 130 and the motor body have better sealing performance, and thus effectively enhancing the steam isolation effect between the sealing sleeve 130 and the motor body.

[0078] Continuing to refer to Figure 5 As shown, the sealing sleeve 130 may further include a third protrusion 135. The third protrusion 135 may be located on the side of the second main body portion 131 facing the flanging ring 113 and abuts against the inner wall of the flanging ring 113. For example, the third protrusion 135 may be a closed annular structure, and the third protrusion 135 may surround the outer periphery of the second main body portion 131 of the sealing sleeve 130.

[0079] The third protrusion 135 may be in a compressed state. The third protrusion 135 in the compressed state has a resilience force, and this resilience force can drive the third protrusion 135 to deform in the direction of the flanging ring 113, enabling the third protrusion 135 to be in closer contact with the flanging ring 113. This can effectively improve the sealing performance of the contact between the third protrusion 135 and the flanging ring 113, making the second main body portion 131 of the sealing sleeve 130 and the flanging ring 113 have better sealing performance, and thus effectively enhancing the steam isolation effect between the sealing sleeve 130 and the flanging ring 113 in the housing 110.

[0080] For example, a plurality of third protrusions 135 may be provided on the outer periphery of the second main body portion 131. The third protrusions 135 may be spaced apart along the axial direction of the sealing sleeve 130. The plurality of third protrusions 135 may provide a seal between the outer periphery of the second main body portion 131 and the flanging ring 113, effectively improving the sealing performance between the sealing sleeve 130 and the flanging ring 113 and enhancing the steam isolation effect between the sealing sleeve 130 and the housing 110.
