It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] As Figures 1 to 4 shown, in this embodiment, the cover assembly includes: an outer cover 10, a metal inner cover 20, and a plurality of pressure limiting valves 30. The metal inner cover 20 is rotatably disposed below the outer cover 10, and a plurality of exhaust pipes 21 are provided on the metal inner cover 20. The plurality of pressure limiting valves 30 are provided corresponding to the plurality of exhaust pipes 21 one by one and are installed on the tops of the corresponding exhaust pipes 21. Among them, one of the plurality of exhaust pipes 21 is located at the rotation center of the metal inner cover 20, and the remaining exhaust pipes 21 are located outside the rotation center of the metal inner cover 20.

[0031] Applying the technical solution of this embodiment, the metal inner cover 20 is rotatably disposed below the outer cover 10, and a plurality of exhaust pipes 21 are provided on the metal inner cover 20. The plurality of pressure limiting valves 30 are provided corresponding to the plurality of exhaust pipes 21 one by one and are installed on the tops of the corresponding exhaust pipes 21. One of the plurality of exhaust pipes 21 is located at the rotation center of the metal inner cover 20, and the remaining exhaust pipes 21 are located outside the rotation center of the metal inner cover 20. Through the above settings, the plurality of exhaust pipes 21 cooperate with the plurality of pressure limiting valves 30 to be able to increase the exhaust volume, and thus can make the exhaust pressure relief efficient, thereby reducing the cooking duration. At the same time, since one of the exhaust pipes 21 is located at the rotation center of the metal inner cover 20 and the remaining exhaust pipes 21 are located outside the rotation center of the metal inner cover 20, there is no need to provide a large avoidance portion on the outer cover 10, and thus the overall processing difficulty of the cover assembly is small. Therefore, the technical solution of this embodiment effectively solves the problem that the exhaust efficiency of cooking appliances in the related art is relatively low, which will cause a relatively long cooking time.

[0032] Specifically, in this embodiment, there are two exhaust pipes 21 and two pressure limiting valves 30. Of course, in other embodiments, the number of exhaust pipes 21 can also be other numbers, such as three, four, or other numbers, and the number of pressure limiting valves 30 is the same as the number of exhaust pipes.

[0033] As Figures 1 to 7 shown, in this embodiment, the cover assembly further includes a sealing assembly 40. The outer cover 10 includes a face cover 11 and a lining 12. The face cover 11 is mounted on the lining 12. The sealing assembly 40 is mounted between the lining 12 and the face cover 11. A plurality of exhaust pipes 21 penetrate through the sealing assembly 40, and a plurality of pressure limiting valves 30 are all located above the sealing assembly 40. The arrangement of the sealing assembly 40 can prevent substances from the outside of the cover assembly from entering between the face cover 11 and the lining 12, and thus can avoid damage to the structure on the lining 12.

[0034] As Figures 4 to 7 shown, in this embodiment, the sealing assembly 40 includes a fixed seat 41 and a seal 42. The seal 42 is sleeved on the plurality of exhaust pipes 21, and the seal 42 is rotatably arranged on the fixed seat 41. The seal 42 can rotate synchronously with the plurality of exhaust pipes 21, so that the seal 42 can always be in contact with the outer side of the exhaust pipe 21, and thus can prevent other substances from entering between the face cover 11 and the lining 12 through the pipe wall of the exhaust pipe 21. At the same time, the rotation of the seal 42 on the fixed seat 41 is more stable.

[0035] As Figures 4 to 7 shown, in this embodiment, the sealing assembly 40 further includes a rotating frame 43. The seal 42 is fixed on the rotating frame 43, and the rotating frame 43 is rotatably arranged on the fixed seat 41. The rotating frame 43 can fix the seal 42, so that the position of the seal 42 is more stable, and thus the rotation stability of the seal 42 is better.

[0036] As Figures 4 to 7 shown, in this embodiment, a connection structure 44 is provided between the seal 42 and the rotating frame 43. The arrangement of the connection structure 44 can effectively connect the seal 42 and the rotating frame 43.

[0037] Specifically, the connection structure 44 includes a connection hole and a connection post. One of the connection hole and the connection post is arranged on the seal 42, and the other of the connection hole and the connection post is arranged on the rotating frame 43. The connection post is provided with a diameter-expanding structure. The connection post is inserted into the connection hole, and the diameter-expanding structure passes through the connection hole and is in limit fit with the seal 42 or the rotating frame 43.

[0038] As Figures 4 to 8 shown, in this embodiment, a friction-reducing rib 45 is provided between the rotating frame 43 and the fixed seat 41. The arrangement of the friction-reducing rib 45 can make the rotation of the rotating frame 43 easier.

[0039] Specifically, the friction-reducing ribs 45 are multiple and arranged at intervals, and the multiple friction-reducing ribs 45 are located on the outer periphery of the central hole 411.

[0040] As Figures 4 to 7As shown, in this embodiment, the seal 42 includes a gasket 421 and a plurality of sleeve portions 422. The plurality of sleeve portions 422 are all connected to the gasket 421. A plurality of exhaust pipes 21 are arranged in one-to-one correspondence with the plurality of sleeve portions 422, and the exhaust pipes 21 are inserted into the corresponding sleeve portions 422. The setting of the gasket 421 can achieve a relatively large sealing area, thereby improving the sealing effect. At the same time, the setting of the sleeve portions 422 can have a relatively large contact area with the exhaust pipes 21, so that the sealing effect between the sleeve portions 422 and the exhaust pipes 21 is better.

[0041] Specifically, the rotating frame 43 includes a body portion and a plurality of mounting cylinders connected to the body portion. The plurality of exhaust pipes 21 are inserted into the corresponding mounting cylinders. The sleeve portions 422 are arranged at the corresponding mounting cylinders.

[0042] As Figure 7 shown, in this embodiment, on the side of the face cover 11 facing the inner lining 12, there are provided an annular sealing rib 111 and a convex sealing rib 112. The convex sealing rib 112 is connected to the annular sealing rib 111 and is located outside the annular sealing rib 111. The metal inner cover 20 has a closed cover position and an open cover position. When the metal inner cover 20 is in the closed cover position, the seal 42 is in interference fit with the annular sealing rib 111. When the metal inner cover 20 is in the open cover position, the seal 42 is in interference fit with the convex sealing rib 112. Through the above settings, the sealing effect between the face cover 11 and the seal 42 can be better.

[0043] It should be noted that when the metal inner cover 20 is in the closed cover position, the interference amount between the seal 42 and the annular sealing rib 111 is greater than 0.1 mm. When the metal inner cover 20 is in the open cover position, the interference amount between the seal 42 and the convex sealing rib 112 is greater than 0.1 mm.

[0044] As Figures 1 to 5 shown, in this embodiment, the plurality of exhaust pipes 21 include a first pipe body 211 and a second pipe body 212. The fixed seat 41 is provided with a central hole 411 and a strip-shaped hole 412. The first pipe body 211 is inserted into the central hole 411, and the second pipe body 212 is movably inserted into the strip-shaped hole 412. The above central hole 411 is the rotation center of the metal inner cover 20. The second pipe body 212 is inserted into the strip-shaped hole 412 and can move in the strip-shaped hole 412, that is, the strip-shaped hole 412 can guide the second pipe body 212, so that the rotation of the metal inner cover 20 is more stable.

[0045] As Figure 1As shown, in this embodiment, an avoidance hole 121 is provided on the inner liner 12, and a plurality of exhaust pipes 21 are inserted through the avoidance hole 121. An installation notch 113 is provided on the face cover 11, and the sealing assembly 40 is sealingly arranged at the installation notch 113. Both the avoidance hole 121 and the installation notch 113 can avoid the exhaust pipes 21, so that the exhaust pipes 21 will not interfere with the inner liner 12 or the face cover 11 when rotating.

[0046] Specifically, in this embodiment, the fixing seat 41 is connected to the face cover 11, and the sealing member 42 is clamped between the fixing seat 41 and the face cover 11.

[0047] According to another aspect of the present application, a cooking appliance is provided. The cooking appliance in this embodiment includes a cover body assembly, and the cover body assembly is the above-mentioned cover body assembly. A plurality of exhaust pipes 21 are provided on the above-mentioned cover body assembly, which can improve the exhaust efficiency and reduce the cooking time. Therefore, the cooking appliance with the above-mentioned cover body assembly also has the above-mentioned advantages.

[0048] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0049] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.

[0050] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0051] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
