The upper cover assembly 100 and the cooking appliance 300 according to the embodiment of the present invention are described below with reference to the accompanying drawings.

Referring to fig. 1, 2, 6 and 7, a cap assembly 100 according to some embodiments of the present invention may include: the upper cover body 10, the locking member 20, the operating member 30, the driving member 40, and the swing link 50.

Specifically, as shown in fig. 2, the locker 20 may be provided to the upper cover body 10, and the locker 20 may be rotatable between the locking position and the unlocking position with respect to the circumference of the upper cover body 10. The operation member 30 is movable relative to the cover body 10, and the movement locus of the operation member 30 includes at least one of a straight line and an arc line, that is, the movement locus of the operation member 30 may be a straight line, an arc line, an assembly of a straight line and an arc line, a combination of a straight line and a straight line, such as a broken line, or a combination of an arc line and an arc line. The driving member 40 may be provided to the upper cover body 10, and the driving member 40 may be connected to the operation member 30.

Therefore, when the operation member 30 moves, the active member 40 can move relative to the upper cover body 10 under the driving of the operation member 30. One end of the swing link 50 is swingably connected to the active member 40, as shown in fig. 6 and 7, the other end of the swing link 50 is rotatably connected to the locking member 20, and the connection portion of the swing link 50 and the locking member 20 deviates from the center of the upper cover body 10, that is, the swing link 50 is eccentrically connected to the locking member 20, so that the arm of force for the swing link 50 to drive the locking member 20 to rotate can be increased, the driving force required for the swing link 50 to drive the locking member 20 to rotate is smaller, the force required for the user to operate the operating member 30 to slide is smaller, and the user operation is more labor-saving.

As shown in fig. 6 and 7, when the operating member 30 moves, the active member 40 can move and drive the swing link 50 to swing, so that an angle of the swing link 50 relative to a moving direction of the operating member 30 can be changed, and when the swing link 50 swings, the locking member 20 can be driven to move to realize rotation between the locking position and the unlocking position.

In the above structure, since the driving member 40 moves and the locking member 20 rotates, with different positions of the locking member 20, a distance between a portion (e.g., the pin 21) of the locking member 20, which is used for connecting with the driving member 40, and a central symmetry plane (as shown by a dotted line in fig. 6) may change, and the set swing link 50 may change an angle during the movement of the driving member 40, and not only transmits power of the driving member 40 to the locking member 20, but also may adapt to a distance between a portion (e.g., the portion) of the locking member 20, which is used for connecting with the driving member 40, and the central symmetry plane when the locking member 20 is at different positions, so that the problem of locking during the movement of the opening and closing cover may be effectively prevented, and particularly, the swing link 50 may rotate relative to the driving member 40, and may also rotate relative to the locking member 20. In some embodiments of the present invention, in the closed state, the angle between the swing link 50 and the active member 40 may be as shown in fig. 6, and in the open state, the angle between the swing link 50 and the active member 40 may be as shown in fig. 7.

According to the upper cover assembly 100 of the embodiment of the invention, by arranging the movable operating member 30, the driving member 40 movable along with the operating member 30 and the swinging connecting rod 50 connected between the operating member 30 and the locking member 20 and capable of swinging, when the operating member 30 moves, the driving member 40 and the swinging connecting rod 50 can be linked, and further the rotation of the locking member 20 can be realized, therefore, the opening and closing of the cover can be realized by moving the operating member 30, the opening and closing of the cover are convenient, labor-saving and smooth, and the connecting part of the swinging connecting rod 50 and the locking member 20 deviates from the center of the upper cover body 10, so that the opening and closing operation is more labor-saving.

Alternatively, as shown in fig. 1, the operating member 30 may be moved in a direction from the edge of the upper cover body 10 toward the center of the upper cover body 10. That is, the operating member 30 can move substantially in the radial direction of the upper cover body 10. Therefore, the design and the manufacture are more convenient, and the operation habit is better met.

The connection structure of the operation member 30 and the driving member 40 is not particularly limited in the present invention, and optionally, as shown in fig. 3 to 5, the operation member 30 may be provided with a connection groove having a downward opening, the driving member 40 is provided with a plurality of connection posts 421, each connection post 421 has a hole, and the plurality of connection posts 421 may be inserted into the connection groove. The bottom wall of the coupling groove, which is the upper side wall of the coupling groove in the embodiment shown in fig. 4 and 5, is provided with a plurality of coupling holes 301. The plurality of connection holes 301 correspond to the holes of the plurality of connection posts 421 one to one. The fasteners penetrate through the holes of the connecting columns and the connecting holes in a one-to-one correspondence mode to connect the operating parts and the driving parts. The holes of each connecting post 421 and the corresponding connecting holes 301 are internally inserted with fasteners such that the operating member 30 and the driving member 40 can be connected by a plurality of fasteners, wherein the fasteners include, but are not limited to, screws or bolts.

Above-mentioned structure is when connecting, and connecting groove can play the effect of holding and tentatively fixing a position the spliced pole, not only makes whole structure more compact firm, more does benefit to the assembly moreover.

It will be appreciated that the positions of the connection recess and the connection post 421 can be interchanged, i.e. the connection recess is provided on the active member 40 and the connection post 421 is provided on the operating member 30, which achieves the same effect as described above. That is, in the embodiment of the present invention, one of the operating member 30 and the active member 40 may be provided with a coupling groove, and the other thereof may be provided with a plurality of coupling posts 421.

It is understood that, in the embodiment of the present invention, the active member 40 and the operation member 30 may be disposed on the same side of the upper cover body 10, or may be disposed on different sides of the upper cover body. When the driving member 40 and the operating member 30 are disposed at the same side of the upper cover body 10, the driving member 40 and the operating member 30 may be directly connected; when the active member 40 and the operation member 30 are disposed on different sides of the upper cover body 10, in order to facilitate the connection of the active member 40 and the operation member 30, an escape structure may be provided on the upper cover body 10.

For example, in some embodiments of the present invention, as shown in fig. 1 and 5, the cap-up body 10 may include: the face cap 14, sometimes referred to as an outer cap. The operation member 30 may be located at an upper side of the face cover 14, the active member 40 may be located at a lower side of the face cover 14, and the face cover 14 is provided with a face cover escape opening 141 that may be used to pass a connection portion of the operation member 30 and the active member 40. For example, when the operation member 30 and the active member 40 are connected by the connection structure of the connection post 421 and the connection hole 301 and the fastener in the foregoing embodiment, the face cover escape opening 141 may escape the connection structure, for example, so that the connection post 421 may be connected with the connection hole 301 through the face cover escape opening 141.

Further, the edge of the face cover escape opening 141 does not contact the connection portion of the operation member 30 and the active member 40. At this time, the face cover avoiding opening 141 has no guiding function on the movement of the operating element 30, and in the translation process of the operating element 30, no friction exists between the connecting part of the operating element 30 and the driving element 40 and the edge of the face cover avoiding opening 141, so that the friction resistance can be reduced, and the user operation is more labor-saving.

In some alternative embodiments of the present invention, as shown in fig. 1, 6 and 7, the operating member 30 may be provided on the front side of the upper cover body 10, the operating member 30 may be moved in the front-rear direction and the extension line of the moving track passes through the center of the upper cover body 10, in which case, the operating member 30 moves on the front side of the center of the upper cover body 10, the moving stroke of the operating member 30 is relatively small and the influence on the overall structure of the upper cover body 10 is small.

As shown in fig. 6 and 7, the front end of the swing link 50 is swingably connected to the rear end of the drive arm 43. During the movement of the operating member 30, the rear end of the swing link 50 may pass through the center of the upper cover body 10 in the front-rear direction, and the rear end of the swing link 50 remains located behind the front end of the swing link 50. That is, in the process of moving the operating piece 30 to open or close the cover, the rear end of the swing link 50 may move between the front side of the center of the cover body 10 and the rear side of the center of the cover body 10 in the front-rear direction, pass through a position corresponding to the center of the cover body 10 in the process of moving, and the distance between the rear end of the swing link 40 and the center of the cover body 10 is smaller than the distance between the front end of the swing link 40 and the center of the cover body 10. Like this, the swing range of swing connecting rod 50 is less, can not take place the whole transfer of fore-and-aft direction, further avoids swing connecting rod 50 to appear blocking to, swing connecting rod 50 can be roughly in the left side or the right side that is located the center of upper cover body 10 drive retaining member 20, and research shows that this kind of setting up the structure is favorable to making the lid of opening and shutting more laborsaving and smooth and easy.

The active guide portion 12 may include two guide ribs provided on the upper surface of the inner cover 13 and arranged in parallel, and the active member 40 may be movably fitted between the two guide ribs to slide, and at this time, both side surfaces of the active member 40 may be formed as active guide fitting portions 51. The guide structure not only has good guiding effect, but also can limit the position of the active part 40 in the direction perpendicular to the moving direction of the active part 40.

Further, as shown in fig. 1, 6 to 9, the operating member 30 may move in a direction from an edge of the upper cover body 10 to a center of the upper cover body 10, and the active member 40 may include: a base body 42 and a drive arm 43, the base body 42 being connected to the operating member 30. One end of the base 42 may be connected to one end of the driving arm 43 to form a bent shape in a horizontal direction perpendicular to the moving direction of the driving piece 40, that is, one end of the base 42 is connected to the driving arm 43 to form the driving piece 40 into a bent shape when viewed from the upper side of the upper cover body 10 downward. The other end of the driving arm 43 is closer to the center of the upper lid body 10 in the moving direction of the driving member 40 than the one end of the driving arm 43, and the other end of the driving arm 43 is connected to the swing link 50, and the driving arm 43 is movably fitted between the two guide ribs to move. Therefore, the driving arm 43 can be guided by the guide ribs, the guide part is closer to the swinging connecting rod 50, the guiding effect is better, the force transmission reliability of the swinging connecting rod 50 and the driving arm 43 can be improved, the size of the driving part 40 is relatively smaller, and the installation of other parts is facilitated.

Alternatively, the base 42 may extend in the left-right direction, and the base 42 may be connected to the operating member 30, for example, with a middle portion of the base 42 connected to the operating member 30. The driving arm 43 may extend from the front to the rear, and alternatively, the driving arm 43 may extend entirely in the front-rear direction, may extend obliquely with respect to the front-rear direction, or may extend in a bent manner. The front end of the driving arm 43 is connected to the left or right end of the base 42, and in the embodiment shown in fig. 6, the driving member 40 may be bent.

As shown in fig. 11, in other embodiments of the present invention, the active guiding portion 12 is a guiding post disposed on the upper surface of the inner lid 13, the active guiding matching portion 41 is a guiding slot disposed on the active component 40, and when the active component 40 moves, the guiding post can slide in the guiding slot to guide the active component 40, so that the guiding effect is good. Naturally, the positions of the guide posts and guide slots can also be interchanged, which also achieves the guiding effect.

Further, as shown with continued reference to fig. 11, the operating member 30 may move in a direction from the edge of the upper cover body 10 toward the center of the upper cover body 10, and the active member 40 may include: a base body 42, a driving arm 43 and a guide arm 44, the base body 42 being connected to the operating member 30. In a horizontal direction perpendicular to the moving direction of the driving element 40, both ends of the base 42 may be connected to one end of the driving arm 43 and one end of the guide arm 44, respectively, to form a bent shape, that is, both ends of the base 42 are connected to the driving arm 53 and the guide arm 44, respectively, to form the driving element 40 into a bent shape bent toward an edge away from the upper cover body 10 when viewed from the upper side of the upper cover body 10 downward. At this time, the driving member 40 may be bent twice, and is substantially in a U shape with an opening facing the center of the upper cover body 10. The length of the driving arm 43 extending along the extending direction of the driving member 40 may be greater than the length of the guide arm 44 extending along the extending direction of the driving member 40, the other end of the driving arm 43 is connected to the swing link 50, and the driving arm 43 and the guide arm 44 are respectively provided with a guide groove.

Like this, can follow the both sides of initiative piece 40 simultaneously and lead to initiative piece 40, not only the guide effect is good, can play better limiting displacement to initiative piece 40 moreover, avoids initiative piece 40 to take place crooked in the removal in-process, can improve the smoothness nature of opening and shutting the lid operation. Meanwhile, the driving part 40 with the structure can ensure that the stability of the whole structure is higher under the condition of smaller material consumption, and the reliability of opening and closing the cover can be further improved. Alternatively, the length of the driving arm 43 extending in the extending direction of the driving member 40 may be greater than the length of the guide arm 44 extending in the extending direction of the driving member 40.

The present invention does not have any special limitation on the connection structure of the driving member 40 and the swinging connecting rod 50, as long as the swinging connecting rod 50 can swing relative to the driving member, so that the swinging connecting rod 50 can adaptively adjust the angle between the swinging connecting rod 50 and the driving member 40, and the locking during the moving process is avoided. Alternatively, as shown in fig. 9 to 11, the driving member 40 may be provided with a mounting column 431, the swing link 50 may be provided with a mounting hole 501, the mounting column 431 may be inserted into the mounting hole 501, an end portion of the mounting column 431 may be provided with an anti-drop portion 432 protruding from an outer circumferential surface thereof and abutting against an edge of the mounting hole 501, an inner hole wall of the mounting hole 501 may be provided with an avoiding groove 503, and the avoiding groove 503 may be used to avoid the anti-drop portion 432 when the connecting column is inserted into the connecting hole.
