In order to solve the problem that the upper cover component is thick in the cooking utensil in the prior art, the utility model provides a cooking utensil.

As shown in fig. 1 to 11, a cooking appliance includes an upper cover assembly 10 and a pot body assembly 20, the upper cover assembly 10 is openably and closably covered on the pot body assembly 20, the pot body assembly 20 has a catching place 21 to be caught with the upper cover assembly 10, the upper cover assembly 10 includes a liner 30 and a handle rotating assembly 40, wherein the handle rotating assembly 40 is rotatably disposed on the liner 30, and the handle rotating assembly 40 has a driving end; and the hook 50 is slidably arranged on the liner 30 and is in driving connection with the driving end of the handle rotating assembly 40, and when the handle rotating assembly 40 rotates to the locking position or the unlocking position, the driving end drives the hook 50 to move in a translation manner so that the hook 50 is separated from or buckled with the buckle position 21.

The cooking utensil comprises an upper cover assembly 10 and a pot body assembly 20, wherein the upper cover assembly 10 is covered on the pot body assembly 20 in an openable and closable manner, the pot body assembly 20 is provided with a buckling position 21 buckled with the upper cover assembly 10, the upper cover assembly 10 comprises a liner 30, a handle rotating assembly 40 and a clasp 50, and the handle rotating assembly 40 is rotatably arranged on the liner 30 and is provided with an unlocking position and a locking position; the hook 50 is movably disposed on the liner 30 and drivingly connected to the handle rotating assembly 40, when the handle rotating assembly 40 rotates to the locking position, the hook 50 is fastened to the locking position 21 to lock the upper cover assembly 10 and the pot body assembly 20, and when the handle rotating assembly 40 rotates to the unlocking position, the hook 50 moves in a translational manner to separate the hook 50 from the locking position 21, so as to unlock the upper cover assembly 10 and the pot body assembly 20.

Because the hook 50 is buckled with or separated from the buckling position 21 through the translational motion, the hook 50 does not move up and down in the interaction process of the hook 50 and the buckling position 21, and the requirement on the thickness of the upper cover assembly 10 is not high. The cover assembly 10 is facilitated by providing the clasp 50 with a translational movement to reduce the thickness of the cover assembly 10 to make the cover assembly 10 lightweight. The hook 50 is drivingly connected to the driving end of the handle rotating element 40, and the handle rotating element 40 drives the hook 50 to move in a translational motion during the rotation process, so as to lock or separate the hook 50 and the lock 21, thereby locking or unlocking the upper lid assembly 10 and the pot body assembly 20.

It should be noted that handle rotator assembly 40 does not have to be in constant contact with clasp 50 during the locking, unlocking, or rotation. As long as the driving end of the handle rotating member 40 contacts the hook 50 within a certain period of movement, the hook 50 can be driven to move.

Example one

As shown in fig. 1 and 2, the upper cover assembly 10 further includes a reset element 60, the reset element 60 is supported between the lining 30 and the hook 50, the driving end drives the hook 50 to disengage from the fastening position 21, and the reset element 60 keeps the hook 50 fastened to the fastening position 21. When the handle rotating assembly 40 is switched from the locking position to the unlocking position, the handle rotating assembly 40 drives the hook 50 to move in a translational manner so that the hook 50 overcomes the action of the reset element 60 and is separated from the buckling position 21, and when the handle rotating assembly 40 is switched from the unlocking position to the locking position, the reset element 60 pushes the hook 50 to reset so as to be buckled with the buckling position 21.

In this embodiment, when the handle rotating assembly 40 is switched from the locking position to the unlocking position, the handle rotating assembly 40 drives the hook 50 to move in a translational manner in a direction close to the central axis of the upper cover assembly 10 when rotating, so as to separate the hook 50 from the hook 21, and further unlock the upper cover assembly 10 and the cooker body assembly 20. In this process, handle rotating assembly 40 is pulling clasp 50 inward all the time, and work is required to overcome the force of restoring member 60.

When the upper cover assembly 10 needs to be covered, the handle rotating assembly 40 needs to be rotated from the unlocking position to the locking position, at this time, the acting force of the handle rotating assembly 40 pushing and pressing the hook 50 inwards is reduced, the hook 50 can move in a translational manner in the direction away from the central axis of the upper cover assembly 10 under the action of the resetting piece 60, so as to realize the buckling of the hook 50 and the buckling position 21, and further realize the locking of the upper cover assembly 10 and the cooker body assembly 20.

In the embodiment shown in fig. 10, the driving end of the handle rotation member 40 has a top contact surface 412, the hook 50 has a guiding surface 521, the guiding surface 521 is disposed to be inclined toward the central axis of the cover assembly 10, and when the handle rotation member 40 rotates, the top contact surface 412 slides along the guiding surface 521 to drive the hook 50 to move. The abutting surface 412 is drivingly connected to the hook 50, and when the handle rotating element 40 is switched from the locked position to the unlocked position, the abutting surface 412 of the rotating rod 41 contacts the hook 50, and during the rotation of the rotating rod 41, the rotating rod 41 drives the hook 50 to move in a translational manner, so that the hook 50 is separated from the holding portion 21.

In the embodiment shown in fig. 10, the handle rotation assembly 40 includes a rotation rod 41, the extended end of the rotation rod 41 has a top connection portion 411, the top connection portion 411 has a top connection surface 412, and during the rotation of the rotation rod 41, the top connection surface 412 slides along the surface of the hook 50. In this embodiment, the top connection portion 411 is a protrusion formed at the end of the outward extending end of the rotating rod 41, and the top connection surface 412 is a surface of the protrusion facing the central axis of the upper cover assembly 10, so that the top connection surface 412 is drivingly connected to the hook 50, when the handle rotating assembly 40 is switched from the locking position to the unlocking position, the top connection surface 412 of the rotating rod 41 contacts the hook 50, and during the rotation of the rotating rod 41, the rotating rod 41 drives the hook 50 to move in a translational manner, so that the hook 50 is separated from the fastening position 21.

Through the cooperation of the top contact surface 412 and the hook 50, the rotation motion of the rotating rod 41 is converted into the translation motion of the hook 50, thereby realizing the motion reversing and ensuring the smooth locking and unlocking process and good operation hand feeling.

In the embodiment shown in fig. 2, the handle 42 of the handle rotation assembly 40 is separate from the rotation rod 41, and the rotation rod 41 is connected to the handle 42 through the lower cover 80 and the upper cover 70 in turn, so that the handle 42 drives the rotation rod 41 to move when rotating. The inner liner 30 is connected with the inner pot cover 90, and the inner liner 30 is positioned above the inner pot cover 90.

As shown in fig. 8 and 9, the clasp 50 includes a main body 51 and a guiding portion 52, wherein the main body 51 has a fastening section 511, and the fastening section 511 is engaged with the fastening position 21; the guide portion 52 is connected to the main body portion 51, and the abutting surface 412 slides along the guide surface 521 of the guide portion 52. When the rotating rod 41 rotates, the top contact surface 412 slides along the guiding surface 521 and drives the guiding portion 52 to move toward the direction close to the central axis of the upper cover assembly 10, so that the locking section 511 of the hook 50 is separated from the locking position 21, thereby unlocking the upper cover assembly 10 and the cooker body assembly 20. It should be noted that it is necessary to ensure that the contact friction between the guiding surface 521 and the abutting surface 412 is proper, so as to avoid the excessive or insufficient friction between the guiding surface 521 and the abutting surface, which results in loss of force or operation slip, thereby affecting the operation feel and the motion reliability.

Alternatively, the guide portion 52 is integrally formed with the main body portion 51. The clasp 50 of this type has a high structural strength, and when the rotary lever 41 and the guide 52 are operated, the force is stably transmitted to the body portion 51, so that the movement of the clasp 50 is stabilized.

As shown in fig. 8 to 10, the abutting surface 412 is a surface of the abutting portion 411 facing away from the fastening position 21, the guiding surface 521 is disposed away from the central axis of the cover assembly 10, the guiding surface 521 is disposed to be inclined toward the central axis of the cover assembly 10, and when the handle rotating assembly 40 is switched from the locking position to the unlocking position, the abutting surface 412 pushes the hooks 50 to move in a translational manner toward the central axis of the cover assembly 10. The inclined orientation of the guiding surface 521 towards the central axis of the cover assembly 10 facilitates the movement of the abutting surface 412 along the guiding surface 521 to push the hook 50 to move in a translational motion towards the central axis of the cover assembly 10.

As shown in fig. 8 and 9, the engaging section 511 is located at the bottom end of the hook 50, and the guide 52 is located at the top end of the hook 50. The specific positions of the engaging section 511 and the guiding portion 52 are determined according to the positions of the engaging portion 21 and the rotating rod 41, respectively, and the height of the hook 50 in the vertical direction is the height difference between the top end of the guiding portion 52 and the bottom end of the engaging section 511. Since the hook 50 does not need to rotate, the hook 50 does not need to move up and down, and the thickness of the upper cover assembly 10 can be reduced to reduce the weight of the upper cover assembly 10 and reduce the occupied space.

As shown in fig. 7, the liner 30 has a radial guide and a height-limiting structure, and at least a portion of the hooks 50 are limited in a limited area formed by the radial guide and the height-limiting structure. In this manner, the radial guide and height stop structures may limit movement of the clip 50 on the liner to allow the clip 50 to be stably positioned on the liner 30.

As shown in fig. 7, the liner 30 has a sliding hole 31 penetrating through the upper and lower surfaces of the liner 30, the radial guiding structure includes two limiting plates 32 located on the upper surface of the liner 30, the two limiting plates 32 are located on two sides of the sliding hole 31, the hook 50 is located between the two limiting plates 32, and the bottom end of the hook 50 passes through the sliding hole 31 and extends out to one side of the pot body assembly 20. The sliding hole 31 is arranged to enable the hook 50 to penetrate through the lining 30 to be matched with the buckle position 21; on the other hand, the clasp 50 can be moved in translation in the sliding hole 31.

As shown in fig. 7, the height limiting structure includes a plurality of limiting catches 321, and the limiting catches 321 are disposed on the surfaces of the opposite sides of the two limiting plates 32 to stop the upward movement of the hook 50. The limiting plate 32 can also limit the moving direction of the hook 50, so as to avoid the movement deviation of the hook 50 and protect the hook 50 to a certain extent. The limiting buckle 321 can prevent the hook 50 from moving upwards, so that the hook 50 is prevented from being separated from the liner 30 in the stress process, and the motion stability of the hook 50 is improved.

As shown in fig. 11, the lining 30 is provided with a clasp protrusion 33 extending toward the clasp 50, and when the clasp 50 moves toward the clasp 21 along the sliding hole 31, the clasp 50 stops moving after contacting the buckling limiting surface of the clasp protrusion 33 to limit the buckling distance of the clasp 50. The arrangement of the buckle position protrusion 33 can ensure that the hook 50 cannot be separated from the liner 30 under the action of the reset member 60, and limit the buckling distance of the hook 50 to avoid the phenomenon that the hook 50 is locked with the buckle position 21 and cannot be opened.

Of course, the inner liner 30 may not be provided with the catching protrusion 33, and the size of the sliding hole 31 may be limited to control the catching distance. Specifically, the edge of the sliding hole 31 on the side away from the central axis of the upper cover assembly 10 can be slightly close to the central axis of the upper cover assembly 10, so that a certain distance is reserved between the sliding hole 31 and the buckling position 21, and even if the hook 50 is buckled with the buckling position 21, the buckling force between the hook 50 and the buckling position 21 is not too large, so that the cover opening operation is facilitated.

The difference from the first embodiment is that the handle rotation assembly 40 and the reset member 60 function just in reverse to the first embodiment. Specifically, the handle rotating assembly 40 enables the hook 50 to be engaged with the fastening position 21 and the reset element 60 keeps the hook 50 disengaged from the fastening position 21, and the reset element 60 is located away from the central axis of the upper cover assembly 10 relative to the hook 50.

Specifically, the reset element 60 keeps the hook 50 separated from the catch 21, when the handle rotation element 40 is switched from the unlocking position to the locking position, the handle rotation element 40 drives the hook 50 to move in a translational manner so that the hook 50 overcomes the effect of the reset element 60 and is buckled with the catch 21, and when the handle rotation element 40 is switched from the locking position to the unlocking position, the reset element 60 pushes the hook 50 to reset, so that the hook 50 is separated from the catch 21. When the handle rotation element 40 is switched from the unlocking position to the locking position, the handle rotation element 40 pushes the hook 50 to move in a translational manner in a direction away from the central axis of the cover assembly 10 during the rotation process, so that the hook 50 is buckled with the buckling position 21 by overcoming the action of the reset element 60. When the handle rotating element 40 is switched from the locking position to the unlocking position, the pushing force of the handle rotating element 40 on the hook 50 is reduced, and under the action of the reset element 60, the hook 50 is pushed by the reset element 60 to the central axis side of the pot body element 20, so that the hook 50 is separated from the buckle position 21, and the upper cover assembly 10 is unlocked from the pot body element 20.

EXAMPLE III

The difference from the first embodiment is that the engagement and disengagement of the hook 50 and the fastening position 21 are realized by the handle rotating assembly 40, and the action of the reset member 60 is not required.

Specifically, the handle rotating assembly 40 and the hook 50 are always connected, and when the handle rotating assembly 40 moves, the hook 50 moves back and forth in a translational manner under the action of the handle rotating assembly 40. When the handle rotation member 40 is switched from the unlocking position to the locking position, the handle rotation member 40 drives the hook 50 to move in a translational manner in a direction close to the buckle position 21 in the rotating process, so that the hook 50 is buckled with the buckle position 21. When the handle rotating assembly 40 is switched from the locking position to the unlocking position, the handle rotating assembly 40 drives the hook 50 to move in a translational manner in a direction away from the buckle position 21 in the rotating process, so that the hook 50 is separated from the buckle position 21.

Specifically, a slot may be formed at the abutting portion 411 of the rotating rod 41, so that at least a portion of the hook 50, for example, the top of the hook 50, is inserted into the slot, and thus, during the rotation of the rotating rod 41, the hook 50 is always in contact with the slot, so that the hook 50 is pushed forward or pulled backward according to the specific movement of the handle rotating assembly 40, thereby achieving unlocking and locking.
