The upper cover assembly 100 of the cooking appliance 300 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 to 4, the upper cover assembly 100 of the cooking appliance 300 according to the embodiment of the present invention may include: the upper cover body 10, the locking member 20, the operating member 30, and the driving member 40.

Specifically, as shown in fig. 2, the locker 20 may be provided to the upper cover body 10, and the locker 20 may be rotated between the locking position and the unlocking position with respect to the circumferential direction of the upper cover body 10. The operation member 30 is movable relative to the upper cover body 10. Alternatively, 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, a combination of a straight line and a straight line, such as a polygonal line, or a combination of an arc line and an arc line. As shown in fig. 3 and 4, the active member 40 may be connected to the locker 20, and the active member 40 may be connected to the operating 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. The driving part 40 is connected with the locking part 20 through the matching of the pin shaft 21 and the shaft hole 401, and the pin shaft 21 deviates from the center of the upper cover body 10, that is, the driving part 40 is eccentrically connected with the locking part 20, so that the arm of force of the driving part 40 driving the locking part 20 to rotate can be increased, the driving part 40 drives the locking part 20 to rotate, the driving force required by the rotation is smaller, the force required by the sliding of the user operation part 30 is smaller, and the user operation is more labor-saving.

It should be noted that, in some embodiments, as shown in fig. 5 and 7, the pin 21 may be disposed on the locking member 20, the shaft hole 401 may be disposed on the driving member 40, and the pin 21 is inserted into the shaft hole 401 to achieve the driving connection between the locking member 20 and the driving member 40. In other embodiments, the positions of the pin 21 and the shaft hole 401 may be interchanged, specifically, the locking member 20 may be provided with the shaft hole 401, and the driving member 40 may be provided with the pin 21, which may also realize the driving connection between the locking member 20 and the driving member 40 by the cooperation of the pin 21 and the shaft hole 401.

As shown in fig. 4 to 7, when the operating element 30 moves, a distance between the locking element 20 and the driving element 40 in the axial direction of the upper cover body 10 may change, so that the pin 21 and the shaft hole 401 relatively move in the axial direction of the upper cover body 10, a position of the pin 21 for fitting with the shaft hole 401 changes in the axial direction of the upper cover body 10, and the pin 21 extends in a non-linear direction in the axial direction of the upper cover body 10, so that the pin 21 is formed as a special-shaped pin, i.e., a non-straight shaft, or a straight shaft inclined to the axial direction of the upper cover body 10.

In the above structure, the movement of the operating member 30 drives the movement of the driving member 40, and further drives the rotation of the locking member 20 relative to the cover body 10. Since the driving member 40 is moved and the locking member 20 is rotated, the distance between the portion of the locking member 20 for connecting with the driving member 40 (e.g., the pin 21 or the shaft hole 401) and the central symmetry plane (shown by a dotted line in fig. 3) may be changed according to the different positions of the rotation of the locking member 20. The pin shaft 21 extends in the axial direction of the upper cover body 10 to form a non-straight line, so that the distance between the position, used for being matched with the shaft hole 401, of the pin shaft 21 and the central symmetry plane can be changed, the power of the driving part 40 can be transmitted to the locking part 20, meanwhile, the distance between the part, used for being connected with the driving part 40, of the locking part 20 and the central symmetry plane can be adaptively changed when the locking part 20 is at different positions, and therefore the problem of blocking of the opening and closing cover in the moving process can be effectively solved.

In some embodiments of the present invention, in the closed state, the position relationship between the locking member 20 and the active member 40 along the axial direction of the upper cap body 10 can be referred to as shown in fig. 5, and in the open state, the position relationship between the locking member 20 and the active member 40 along the axial direction of the upper cap body 10 can be referred to as shown in fig. 7.

In the present invention, opening the lid is not generally considered to open the opening of the pot assembly 200 of the cooking device 300 by opening the lid assembly 100, and closing the lid is not considered to close the opening of the pot assembly 200 of the cooking device 300 by closing the lid assembly 100. When the locking member 20 is in the locking position by closing the lid, the upper cover assembly 100 is locked with the pot body assembly 200 of the cooking utensil 300, and the upper cover assembly 100 cannot be separated from the pot body assembly 200; when the locking member 20 is unlocked by opening the cover, the upper cover assembly 100 is unlocked from the pot assembly 200 of the cooking utensil 300, and the upper cover assembly 100 can move relative to the pot assembly 200 to be separated from the pot assembly 200. In the embodiment where pan body assembly 200 is hinged to upper cover assembly 100, separation of upper cover assembly 100 from pan body assembly 200 may be understood as rotation of upper cover assembly 100 about the hinge axis to open the opening of pan body assembly 200.

In the invention, the structure of the pin shaft 21 can be flexibly set according to actual conditions. Alternatively, the pin 21 may extend in an arc shape, a curved line, a straight line inclined with respect to the axial direction of the upper cap body 10, or the like. For example, in some embodiments, as shown in fig. 3, 5 and 12, upper lid body 10 may include inner lid 12, and active member 40 and locking member 20 may be provided on the upper and lower sides of inner lid 12, respectively, to facilitate mounting of active member 40 and mating of locking member 20 with pan body assembly 200. The inner cup 12 can be equipped with the inner cup that is used for making the round pin axle 21 to pass and dodges hole 121, and the inner cup dodges hole 121 and extends in order to form the circular arc hole along the circumference of inner cup 12, and the center of lid body 10 is the centre of a circle above the circular arc hole, and round pin axle 21 forms into the circular arc post, and the circular arc post extends along upper and lower direction to the center protrusion of lid body 10 is covered to the middle part of circular arc post.

From this, retaining member 20 when rotating for upper cover body 10, the circular arc hole can lead retaining member 20 with the cooperation of circular arc post, makes retaining member 20 rotate around the center of upper cover body 10 to the circular arc post with circular arc hole complex position and the distance at the center of upper cover body 10 change gradually, with the rotation of adaptation retaining member 20, frictional resistance is littleer when circular arc post and circular arc hole take place relative motion, is favorable to improving the smooth and easy nature of opening and shutting the lid.

Of course, the configuration of the pin 21, including but not limited to the circular arc column shown in fig. 5 and 7, is only required to meet the requirement that the pin 21 and the shaft hole 401 cooperate to accommodate the rotation of the locking member 20. For example, in other embodiments, the distance between the pin 21 and the axis of the upper lid body 10 may gradually increase from bottom to top, or gradually increase and then gradually decrease, or the distance between the pin 21 and the axis of the upper lid body 10 may gradually decrease from bottom to top.

In the present invention, when the distance between the driving member 40 and the locking member 20 along the axial direction of the upper cap body 10 changes, the distance between the driving member 40 and the upper cap body 10 along the axial direction of the upper cap body 10 may change, and the distance between the locking member 20 and the upper cap body 10 along the axial direction of the upper cap body 10 does not change; the distance between the driving member 40 and the upper cap body 10 along the axial direction of the upper cap body 10 may be constant, and the distance between the locking member 20 and the upper cap body 10 along the axial direction of the upper cap body 10 may be changed; or the distances between the driving member 40 and the locking member 20 and the upper cap body 10 in the axial direction of the upper cap body 10 may be varied.

Alternatively, in some embodiments, as shown in fig. 8 and 9, the locker 20 may be provided with a second fitting slope 52, the second fitting slope 52 being obliquely arranged with respect to the axial direction of the upper cap body 10, as shown in fig. 10, and the upper cap body 10 may be provided with a first fitting slope 51, the first fitting slope 51 being oblique to the axial direction of the upper cap body 10. When the operating member 30 moves, the first matching inclined surface 51 and the second matching inclined surface 52 can slide in a matching manner, so that the locking member 20 and the upper cover body 10 can move axially relative to each other, and further, the distance between the active member 40 and the locking member 20 along the axial direction of the upper cover body 10 can be changed. The locking piece 20 is matched with the surface of the upper cover body 10, so that the relative movement is more stable, and the reliability and the smoothness of opening and closing the cover are improved.
