[0003] In the related art, the opening member can drive the transmission member to move on the upper cover, and then drive the metal cover to rotate. The movement of the transmission member requires a large space, so a large space needs to be provided on the upper cover for the transmission member to move, resulting in a large size of the cover. Summary of the Utility Model

[0004] The main object of the present utility model is to provide a cover assembly and a cooking appliance having the same, so as to solve the problem that the transmission member in the related art needs a large space to move, resulting in a large size of the cover.

[0005] To achieve the above object, according to one aspect of the present utility model, a cover assembly is provided, including: an upper cover; a metal inner cover rotatably arranged below the upper cover, the metal inner cover having a locked position and an unlocked position; a rotating structure rotatably arranged on the upper cover, the rotating structure being connected to the metal inner cover; a moving member eccentrically arranged on the rotating structure, the moving member being able to rotate relative to the rotating structure, and a first connecting portion being arranged on the moving member; an opening member arranged on the upper cover and able to drive the metal inner cover to rotate, the opening member having an operating portion and a second connecting portion, the first connecting portion and the second connecting portion being inserted and matched with each other and having a movable gap. When the opening member is operated, the first connecting portion and the second connecting portion move relative to each other and drive the moving member to move along a preset curve direction. When the moving member moves, it can drive the rotating structure to rotate relative to the moving member and make the metal inner cover switch between the locked position and the unlocked position.

[0006] Applying the technical solution of the present utility model, the metal inner cover is rotatably arranged below the upper cover, and the metal inner cover has a locking position and an unlocking position. The rotating structure is rotatably arranged on the upper cover, and the rotating structure is connected to the metal inner cover. The moving member is eccentrically arranged on the rotating structure, and the moving member and the rotating structure can rotate relative to each other. A first connecting portion is arranged on the moving member, and the opening member is arranged on the upper cover and can drive the metal inner cover to rotate. The opening member has an operating portion and a second connecting portion that is inserted and cooperated with the first connecting portion. There is an activity gap between the first connecting portion and the second connecting portion. When the opening member is operated, the first connecting portion and the second connecting portion can move relative to each other and drive the moving member to move along a preset curve direction. When the moving member moves, it can drive the rotating structure to rotate relative to the moving member and make the metal inner cover switch between the locking position and the unlocking position. Through the above settings, the moving member is eccentrically arranged on the rotating structure, and when the moving member moves, it can drive the rotating structure to rotate. At the same time, in order to avoid the situation of jamming between the opening member and the moving member, the moving member can rotate relative to the rotating structure. And in order to make it easier for the moving member to drive the rotating structure to rotate, there is an activity gap between the first connecting portion and the second connecting portion, which can ensure that the moving member moves along a preset curve. Since the moving member is arranged on the rotating structure, and the rotating structure drives the metal inner cover to rotate by rotation, the moving path of the moving member is smaller, and the space occupied by the rotating structure is also smaller. Therefore, the technical solution of the present application can effectively solve the problem in the related art that the transmission member needs a large space to move, resulting in a larger size of the cover body.

[0007] Further, the preset curve direction is an arc direction, and the center of the circle where the arc direction is located is on the rotation axis of the rotating structure. The above settings can ensure that the moving member drives the rotating structure to rotate.

[0008] Further, the rotating structure includes a rotating main body and a receiving seat arranged on the rotating main body. The receiving seat has a receiving concave portion, and the moving member is movably arranged in the receiving concave portion. The setting of the receiving concave portion can limit the position of the moving member, so that the moving member is always stably connected to the receiving seat, thereby ensuring that the moving member drives the rotating structure to rotate.

[0009] Further, the cover body assembly further includes a first anti-friction structure, which is arranged between the bottom surface of the moving member and the bottom surface of the receiving concave portion, and / or the cover body assembly further includes a second anti-friction structure, which is arranged between the side surface of the moving member and the hole wall of the receiving concave portion. The settings of the first anti-friction structure and the second anti-friction structure can make the relative rotation between the moving member and the receiving seat easier.

[0010] Further, the cover assembly further includes a limiting structure disposed between the rotating body and the moving member, and the limiting structure can limit the rotation angle of the moving member.

The structures of the limiting block and the notch portion are simple and easy to set, and the limiting block can be in limiting cooperation with the side wall of the notch portion.

[0012] Further, the moving member includes a base body and a frame body located on the base body. The first connecting portion is disposed on the frame body, and the base body is located within the receiving recess. The base body can be stably located within the receiving recess, and the frame body can cooperate with the second connecting portion.

[0013] Further, one of the first connecting portion and the second connecting portion includes a connecting groove, and the other of the first connecting portion and the second connecting portion includes a connecting post. The connecting post is inserted into the connecting groove from the notch of the connecting groove. The structures of the connecting groove and the connecting post are simple, and the connecting post can be inserted into the connecting groove and can move within the connecting groove.

[0014] Further, both ends of the connecting groove are open, and both ends of the connecting post extend out of both ends of the connecting groove. When operating the opening cover member, the connecting post can move within the connecting groove and drive the moving member to move.

[0015] Further, the frame body includes a first vertical plate and a second vertical plate disposed at intervals. The connecting groove is formed between the first vertical plate and the second vertical plate. A first avoidance portion is provided on one side of the first vertical plate facing the second vertical plate, and a second avoidance portion is provided on one side of the second vertical plate facing the first vertical plate. The first avoidance portion is located at the corner of the first vertical plate, and the second avoidance portion is located at the corner of the second vertical plate. The structures of the first vertical plate and the second vertical plate are simple. The first vertical plate and the second vertical plate are disposed at intervals and form a connecting groove therebetween. The provision of the first avoidance portion and the second avoidance portion can make it easier for the connecting post to be inserted into the connecting groove.

[0016] Further, the first vertical plate has a first side and a second side, and the second vertical plate has a first side and a second side. The first side of the first vertical plate and the first side of the second vertical plate are arranged oppositely, and the second side of the first vertical plate and the second side of the second vertical plate are arranged oppositely. The first avoidance portion is located on the first side of the first vertical plate, and the second avoidance portion is located on the second side of the second vertical plate. Through the above arrangement, no matter what angle the moving member is in, the connecting column can be inserted into the connecting groove at a fixed angle. Specifically, when the connecting groove and the connecting column are not directly opposite, the connecting column can contact the first avoidance portion or the second avoidance portion. Further, when the connecting column contacts the first avoidance portion or the second avoidance portion, it can drive the moving member to rotate so that the connecting column is directly opposite to the connecting groove and ensure that the connecting column can be inserted into the connecting groove.

In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. 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.

[0053] As Figures 1 to 9 shown, in this embodiment, the cover assembly includes: an upper cover 10, a metal inner cover 20, a rotating structure 30, a moving member 40, and an opening member 50. The metal inner cover 20 is rotatably provided below the upper cover 10, and the metal inner cover 20 has a locking position and an unlocking position. The rotating structure 30 is rotatably provided on the upper cover 10, and the rotating structure 30 is connected to the metal inner cover 20. The moving member 40 is eccentrically provided on the rotating structure 30, and the moving member 40 and the rotating structure 30 can rotate relative to each other. A first connecting portion 41 is provided on the moving member 40. The opening member 50 is provided on the upper cover 10 and can drive the metal inner cover 20 to rotate. The opening member 50 has an operating portion 51 and a second connecting portion 52. The first connecting portion 41 and the second connecting portion 52 are inserted and matched with each other and have an activity gap. When the opening member 50 is operated, the first connecting portion 41 and the second connecting portion 52 move relative to each other and drive the moving member 40 to move along a preset curve direction. When the moving member 40 moves, it can drive the rotating structure 30 to rotate relative to the moving member 40 and cause the metal inner cover 20 to switch between the locking position and the unlocking position.

[0054] Applying the technical solution of this embodiment, the metal inner cover 20 is rotatably arranged below the upper cover 10, and the metal inner cover 20 has a locking position and an unlocking position. The rotating structure 30 is rotatably arranged on the upper cover 10, and the rotating structure 30 is connected to the metal inner cover 20. The moving member 40 is eccentrically arranged on the rotating structure 30, and the moving member 40 can rotate relative to the rotating structure 30. A first connecting portion 41 is arranged on the moving member 40, and the opening member 50 is arranged on the upper cover 10 and can drive the metal inner cover 20 to rotate. The opening member 50 has an operating portion 51 and a second connecting portion 52 that is inserted and cooperated with the first connecting portion 41. There is an activity gap between the first connecting portion 41 and the second connecting portion 52. When the opening member 50 is operated, the first connecting portion 41 and the second connecting portion 52 can move relative to each other and drive the moving member 40 to move along a preset curve direction. When the moving member 40 moves, it can drive the rotating structure 30 to rotate relative to the moving member 40 and cause the metal inner cover 20 to switch between the locking position and the unlocking position. Through the above settings, the moving member 40 is eccentrically arranged on the rotating structure 30, and when the moving member 40 moves, it can drive the rotating structure 30 to rotate. At the same time, in order to avoid the situation where the opening member 50 is stuck with the moving member 40, the moving member 40 can rotate relative to the rotating structure 30. And in order to make it easier for the moving member 40 to drive the rotating structure 30 to rotate, there is an activity gap between the first connecting portion 41 and the second connecting portion 52, which can ensure that the moving member 40 moves along a preset curve. Since the moving member 40 is arranged on the rotating structure 30, and the rotating structure 30 drives the metal inner cover 20 to rotate through rotation, the moving path of the moving member 40 is smaller, and the space occupied by the rotating structure 30 is also smaller. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the transmission member needs a large space to move, resulting in a larger size of the cover body.

[0055] It should be noted that the above activity gap includes an up-and-down activity gap and a left-and-right activity gap.

The cover assembly further includes a second anti-friction structure 62. The second anti-friction structure 62 is provided between the side surface of the moving member 40 and the hole wall of the receiving recess 321. The provision of the first anti-friction structure 61 and the second anti-friction structure 62 can make the relative rotation of the moving member 40 and the receiving seat 32 easier.

[0061] In this embodiment, the first anti-friction structure 61 includes a plurality of protruding members. The protruding members are spaced apart and provided on the bottom surface of the receiving recess 321. Specifically, the top surface of the protruding member is arc-shaped, so that the contact area between the protruding member and the moving member 40 is smaller.

[0062] The second anti-friction structure 62 includes a plurality of anti-friction ribs arranged at intervals. The plurality of anti-friction ribs are provided on the side wall of the moving member 40. The contact area between the anti-friction ribs and the side wall of the receiving recess 321 is small, which can further make the rotation of the moving member 40 easier.

[0063] As Figures 10 to 12 , Figure 15 , Figure 20 and Figure 23 As shown, in this embodiment, the cover assembly further includes a limiting structure 63. The limiting structure 63 is provided between the rotating body 31 and the moving member 40. The limiting structure 63 can limit the rotation angle of the moving member 40. The provision of the limiting structure 63 can limit the rotation angle of the moving member 40.

[0064] As Figures 10 to 12 , Figure 15 , Figure 20 and Figure 23As shown, in this embodiment, the limiting structure 63 includes a notch portion 631 and a limiting block 632. The limiting block 632 can move within the notch portion 631. One of the notch portion 631 and the limiting block 632 is provided on the rotating body 31, and the other of the notch portion 631 and the limiting block 632 is provided between the moving member 40. The structures of the limiting block 632 and the notch portion 631 are simple and easy to set, and the limiting block 632 can be in limiting cooperation with the side wall of the notch portion 631.

[0065] Specifically, in this embodiment, the notch portion 631 is provided on the receiving seat, and the limiting block 632 is provided on the rotating body. The notch portion has a fan-shaped structure, and the angle of the fan-shaped structure is 30°. Of course, the above angle can be any value between 15° and 60°.

[0066] As Figures 10 to 15 and Figure 23 shown, in this embodiment, the moving member 40 includes a seat body 42 and a frame body 43 located on the seat body 42. The first connecting portion 41 is provided on the frame body 43, and the seat body 42 is located within the receiving recess 321. The seat body 42 can be stably located within the receiving recess 321, and the frame body 43 can cooperate with the second connecting portion 52.

[0067] The seat body 42 is a circular block, and both the first anti-friction structure 61 and the second anti-friction structure 62 are provided on the seat body 42.

[0068] Specifically, in this embodiment, the cover assembly further includes a screw, and the screw connects the seat body 42 and the receiving seat 32.

[0069] As Figures 10 to 15 and Figure 23 shown, in this embodiment, one of the first connecting portion 41 and the second connecting portion 52 includes a connecting groove, and the other of the first connecting portion 41 and the second connecting portion 52 includes a connecting post. The connecting post is inserted into the connecting groove from the notch of the connecting groove. The structures of the connecting groove and the connecting post are simple, and the connecting post can be inserted into the connecting groove and can move within the connecting groove.

[0070] Specifically, in this embodiment, the connecting groove is provided on the moving member 40, and the connecting post is provided on the opening cover member 50. Of course, the connecting groove can also be provided on the opening cover member 50, and the connecting post can be provided on the moving member 40.

[0071] As Figures 10 to 15 and Figure 23 shown, in this embodiment, both ends of the connecting groove are open, and both ends of the connecting post extend out of both ends of the connecting groove. When operating the opening cover member 50, the connecting post can move within the connecting groove and drive the moving member 40 to move.

[0072] When operating the opening cover member 50, the connecting column can move synchronously in the height direction and the width direction of the connecting groove. Specifically, when the opening cover member 50 drives the metal inner cover 20 to move from the locked position to the unlocked position, the connecting column moves from the bottom of the connecting groove to the notch of the connecting groove, and at the same time, the connecting column moves in the left-right direction within the connecting groove.

[0073] In an embodiment not shown in the figure, both ends of the connecting groove are closed, the connecting column is inserted into the connecting groove along its axial direction, the connecting column and the connecting groove can move relatively, and when the opening cover member 50 moves, the connecting column can move within the connecting groove and can drive the moving member 40 to move.

[0074] As Figures 10 to 15 and Figure 23 shown, in this embodiment, the moving member 40 includes a seat body 42 and a frame body 43 located on the seat body 42. The frame body 43 includes a first vertical plate 431 and a second vertical plate 432 arranged at intervals. The connecting groove is formed between the first vertical plate 431 and the second vertical plate 432. A first avoiding portion 4311 is provided on the side of the first vertical plate 431 facing the second vertical plate 432, and a second avoiding portion 4321 is provided on the side of the second vertical plate 432 facing the first vertical plate 431. The first avoiding portion 4311 is located at the corner of the first vertical plate 431, and the second avoiding portion 4321 is located at the corner of the second vertical plate 432. The structures of the first vertical plate 431 and the second vertical plate 432 are simple. The first vertical plate 431 and the second vertical plate 432 are arranged at intervals and form a connecting groove therebetween. The settings of the first avoiding portion 4311 and the second avoiding portion 4321 can make it easier for the connecting column to be inserted into the connecting groove.

[0075] It should be noted that, as Figure 23 shown, the corner of the above-mentioned first vertical plate 431 refers to the end of the side of the first vertical plate 431 far from the seat body 42, and the corner of the second vertical plate 432 refers to the end of the side of the second vertical plate 432 far from the seat body 42.

[0076] As Figures 10 to 15 and Figure 23As shown, in this embodiment, the first vertical plate 431 has a first side portion and a second side portion, and the second vertical plate 432 has a first side portion and a second side portion. The first side portion of the first vertical plate 431 and the first side portion of the second vertical plate 432 are arranged opposite to each other, and the second side portion of the first vertical plate 431 and the second side portion of the second vertical plate 432 are arranged opposite to each other. The first avoidance portion 4311 is located on the first side portion of the first vertical plate 431, and the second avoidance portion 4321 is located on the second side portion of the second vertical plate 432. Through the above arrangement, no matter what angle the moving member 40 is in, the connecting column can be inserted into the connecting groove at a fixed angle. Specifically, when the connecting groove and the connecting column are not directly opposite to each other, the connecting column can contact the first avoidance portion 4311 or the second avoidance portion 4321. Further, when the connecting column contacts the first avoidance portion 4311 or the second avoidance portion 4321, it can drive the moving member 40 to rotate so that the connecting column is directly opposite to the connecting groove and ensure that the connecting column can be inserted into the connecting groove.

[0077] As Figures 10 to 22 shown, in this embodiment, the cover assembly further includes a mounting bracket 64. The mounting bracket 64 is connected to the upper cover 10, and the rotating structure 30 is rotatably arranged on the mounting bracket 64. The arrangement of the mounting bracket 64 can make the position of the rotating structure 30 more stable and make the rotating state of the rotating structure 30 stable.

[0078] As Figures 10 to 22 shown, in this embodiment, the cover assembly further includes a third anti-friction structure 65 arranged between the mounting bracket 64 and the rotating structure 30. The arrangement of the third anti-friction structure 65 can make the rotation of the rotating structure 30 easier.

[0079] As Figure 11 and Figure 13 shown, in this embodiment, the third anti-friction structure 65 includes an elastic member 651 and a top column 652. An assembly hole 641 is arranged on the mounting bracket 64. The elastic member 651 is arranged in the assembly hole 641. The top column 652 is in abutting cooperation with the elastic member 651. The top surface of the top column 652 protrudes from the mounting bracket 64 and is in supporting cooperation with the rotating structure 30. The contact area between the top column 652 and the rotating structure 30 is small, which makes the rotation of the rotating structure 30 easier. At the same time, since the top column 652 is in abutting cooperation with the elastic member 651, the top column 652 can float up and down, which can ensure that the top column 652 is always in contact with the rotating structure 30.

[0080] As Figure 16 shown, in this embodiment, a guiding groove 33 is arranged on the side of the rotating structure 30 facing the mounting bracket 64. The top column 652 is movably inserted into the guiding groove 33. The top column 652 can be inserted into the guiding groove 33 and move in the guiding groove 33, which makes the rotation direction of the rotating structure 30 more stable.

[0081] As Figures 10 to 20 shown, in this embodiment, the rotating body 31 includes a rotating frame 311, a sealing gasket 312, and a fixing ring 313. The sealing gasket 312 is disposed between the rotating frame 311 and the fixing ring 313. The setting of the sealing gasket 312 can achieve sealing and prevent other substances from entering the interior of the upper cover 10. The rotating frame 311 and the fixing ring 313 can fix the sealing gasket 312, thereby making the position of the sealing gasket 312 more stable.

[0082] An insertion structure is provided between the fixing ring 313 and the rotating frame 311. The insertion structure includes an annular protrusion and an annular groove that are inserted and matched. One of the annular protrusion and the annular groove is disposed on the side of the rotating frame 311 facing the fixing ring 313, and the other of the annular protrusion and the annular groove is disposed on the side of the fixing ring 313 facing the rotating frame 311. The edge of the sealing gasket 312 is located between the annular protrusion and the annular groove. The outer periphery of the sealing gasket 312 is clamped between the annular protrusion and the annular groove. In this way, the outer periphery of the sealing gasket 312 is bent between the annular protrusion and the annular groove, thereby making the contact area between the outer periphery of the sealing gasket 312 and the annular protrusion better, and thus making the fixing of the sealing gasket 312 more stable.

[0083] Specifically, the rotating structure 30 of this embodiment integrates a sealing function and a transmission function, that is, two functions are realized by one part, which can effectively reduce the complexity of the structure, and thus make the structure of the cover assembly relatively simple.

[0084] As Figure 1 、 Figure 2 and Figure 10 shown, in this embodiment, the cover assembly further includes a mounting seat 66 disposed above the upper cover 10 and a steam cover mounted on the mounting seat 66. The rotating structure 30 is disposed below the mounting seat 66, and the cover opening member 50 is connected to the mounting seat 66. The mounting seat 66 is disposed on the upper cover 10, the rotating structure 30 is rotatably disposed below the mounting seat 66, and the cover opening member 50 is connected to the mounting seat 66, thereby making the position of the cover opening member 50 more stable.

[0085] The cover assembly further includes an exhaust pipe and a pressure limiting valve. The exhaust pipe penetrates through the upper cover and is communicated with the metal inner cover. The pressure limiting valve is disposed at the top of the exhaust pipe. The exhaust pipe penetrates through the rotating structure, and the pressure limiting valve is located inside the mounting seat.

[0086] Specifically, there are two exhaust pipes and two pressure limiting valves. The two exhaust pipes and the two pressure limiting valves are arranged in one-to-one correspondence. One exhaust pipe is located at the rotation center of the rotating structure, and the other exhaust pipe is eccentrically arranged. The cooperation of the two exhaust pipes and the two pressure limiting valves can increase the exhaust volume, thereby enabling a relatively high exhaust pressure relief efficiency, reducing the cooking duration. At the same time, since one exhaust pipe is located at the rotation center of the metal inner cover and the other exhaust pipes are located outside the rotation center of the metal inner cover, there is no need to provide a large avoidance portion on the upper cover 10, thus reducing the overall processing difficulty of the cover assembly.

[0087] The rotating frame 311 is provided with an avoidance notch located between the two exhaust pipes. The avoidance notch is used to avoid the exhaust lever, and the exhaust lever can push the pressure limiting valve for exhaust operation.

[0088] The gasket 312 is located below the pressure limiting valve, which can prevent external substances of the cover assembly from entering the upper cover 10, thus avoiding damage to the structure on the upper cover 10. The gasket includes a sheet body portion and a plurality of annular portions. The plurality of annular portions are all connected to the sheet body portion. The plurality of exhaust pipes are arranged in one-to-one correspondence with the plurality of annular portions, and the exhaust pipes are arranged through the corresponding annular portions. The setting of the sheet body portion can achieve a relatively large sealing area, thereby improving the sealing effect. At the same time, the setting of the annular portions can have a relatively large contact area with the exhaust pipes, so that the sealing effect between the annular portions and the exhaust pipes is better.

[0089] As Figure 11 shown, in this embodiment, the cover assembly further includes a cold air push rod structure 70. The cold air push rod structure 70 includes: a main body rod portion 71, a reset portion 72, and a pressing operation portion 73; the reset portion 72 is connected to the main body rod portion 71; the pressing operation portion 73 is connected to the main body rod portion 71 and is spaced from the reset portion 72; wherein the reset portion 72 and the pressing operation portion 73 are both located at the same end of the main body rod portion 71. The reset portion 72 and the pressing operation portion 73 are both connected to the main body rod portion 71, the reset portion 72 and the pressing operation portion 73 are spaced apart, and the reset portion 72 and the pressing operation portion 73 are both located at the same end of the main body rod portion 71. The reset portion 72 can reset the cold air push rod structure 70, the pressing operation portion 73 enables the user to perform operations, and the main body rod portion 71 can correspond to the cold air rod, thereby driving the cold air rod. Through the above settings, the reset portion 72 and the pressing operation portion 73 can avoid other structures, making the installation position of the cold air push rod structure 70 more flexible.

[0090] As Figure 11As shown, in this embodiment, the cover assembly further includes a spring 80, a stopper, and a cold air rod. The cold air rod is arranged to be vertically floating. The main rod portion 71 of the cold air push rod structure 70 is arranged corresponding to the cold air rod. The stopper is arranged at the top of the reset portion 72, and the spring 80 is arranged between the stopper and the upper cover 10. The spring 80 can reset the cold air push rod structure 70, so that the cold air push rod structure 70 is maintained at a fixed position. When the cold air rod cannot move downward, the user can operate the pressing operation portion 73, so that the cold air rod moves downward. After pressing, the spring 80 can drive the cold air push rod structure 70 to reset.

[0091] In this embodiment, there is a gap between the axis of the main rod portion 71 and the axis of the reset portion 72, and there is a gap between the axis of the main rod portion 71 and the axis of the pressing operation portion 73. The above gaps can be designed according to the actual situation, so that the position of the cold air push rod structure 70 is more reasonable, and there is no need to make an avoidance design on the upper cover.

[0092] It should be noted that the shape of the cold air push rod structure 70 in this embodiment can also be "h"-shaped, three-pronged or other shapes.

[0093] As Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 and Figure 24 As shown, in this embodiment, the cover opening member 50 further includes a hinge shaft 53 and a connecting arm 54. The hinge shaft 53 is hingedly connected to the mounting seat 66. The first end of the connecting arm 54 is connected to the hinge shaft 53, the second end of the connecting arm 54 is connected to the operation portion 51, and the second connecting portion 52 is arranged at the second end of the connecting arm 54. The cover opening member 50 can swing. When the cover opening member 50 swings, the second connecting portion 52 can push against the first connecting portion 41, so that the rotating structure 30 can rotate.

[0094] Specifically, in this embodiment, the cover opening member 50 is a lifting handle. Of course, in other embodiments, the cover opening member 50 can be a pushing and pulling member, a rotating member, etc.

[0095] In this embodiment, the rotating structure 30 is connected to the metal inner cover 20 and drives the metal inner cover 20 to rotate. Of course, in other embodiments, the rotating structure 30 can be matched with the exhaust pipe. When the rotating structure 30 rotates, the rotating structure 30 pushes against the exhaust pipe, and the exhaust pipe can drive the metal inner cover 20 to rotate under the force.

[0096] The using process of the cover assembly in this embodiment is as follows:

[0097] Operate the lifting handle. When the lifting handle swings, the connecting column also swings and can push against the connecting groove in the connecting groove, so that the moving part 40 moves along the preset curve direction, which can drive the rotating structure 30 to rotate. Since the rotating structure 30 is connected to the metal inner cover 20, the metal inner cover 20 can be driven to rotate when the rotating structure 30 rotates.

[0098] According to another aspect of the present application, a cooking appliance is provided. The cooking appliance in this embodiment includes a lid assembly, and the lid assembly is the above-mentioned lid assembly. The rotation of the above-mentioned metal inner cover 20 is realized through the cooperation of the rotating structure 30, the moving part 40 and the lid opening part 50. The moving part 40 is arranged on the rotating structure 30, and the moving path of the moving part 40 is the preset curve direction. In this way, when driving the metal inner cover 20 to rotate, only the rotating structure 30 needs to rotate to achieve it. The moving path of the moving part 40 is small, and the space occupied by the rotating structure 30 is also small, so that the size of the lid assembly is small. Therefore, the cooking appliance with the above-mentioned lid assembly also has the above-mentioned advantages.

[0099] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, 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 invention 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 should not be construed as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0100] 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 of the device. For example, if the device in the figure 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 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 for the spatial relative descriptions used here will be made.

[0101] 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 declaration, the above terms have no special meaning, so it should not be construed as a limitation on the protection scope of the present utility model.
