In addition, the operating member 50 may also have an intermediate position, which is located between the first position and the second position. When the operating member 50 is at the intermediate position, the exhaust valve 40 is in the second open state in which the cooking chamber 101 communicates with the outside, and when the operating member 50 is at the intermediate position, it is not restricted by the restricting member 62.

Therefore, when the operating element 50 slides to the middle position under the action of external force, the first resetting element 54 deforms, the cooking cavity 101 is communicated with the outside, the cooking utensil 100 can be depressurized, and when the external force applied to the operating element 50 is removed, the restoring force of the first resetting element 54 enables the operating element 50 to restore to the second position due to the fact that the operating element 50 is not limited, the exhaust valve 40 is switched to the closed state, and the depressurization is stopped. The opening degree of the exhaust valve 40 in the second opening state is smaller than that of the exhaust valve 40 in the first opening state, that is, the pressure relief rate of the exhaust valve 40 in the second opening state is lower, the pressure relief rate of the exhaust valve 40 in the first opening state is higher, and the pressure relief in stages can be realized by the reciprocating sliding of the operating member 50 between the second position and the intermediate position, so that the pressure relief manner is more diversified.

According to the utility model discloses a some embodiments, as shown in fig. 4 and fig. 6, first piece 54 that resets can be coil spring, slider 53's one end can be equipped with downwardly extending's limiting plate 532, coil spring's one end can offset with limiting plate 532, and coil spring's the other end can offset with lid body 30, operating part 50 can compress coil spring along the gliding in-process of first direction, and operating part 50 is not when the spacing effect of limiting part 62, the restoring force of compressed coil spring can promote operating part 50 and reset to the second position along the second direction.

Optionally, one side of the limiting plate 532 towards coil spring may be further provided with a mounting column or a mounting groove, one end of the coil spring may be sleeved on the mounting column or inserted into the mounting groove, and the mounting column or the mounting groove may limit the coil spring to prevent the coil spring from being dislocated in the sliding process of the operating element 50 to affect the reset effect on the operating element 50.

In some embodiments of the utility model, as shown in fig. 4, the one end of slider 53 can be equipped with non-circular locating hole 531, dial button 52 can be equipped with downwardly extending's reference column 521, reference column 521 matches with non-circular locating hole 531's shape, reference column 521 inserts and can realize dialling the connection of button 52 and slider 53 in the non-circular locating hole 531 to make and dial button 52 and slider 53 relatively fixed, prevent that the user from pushing and pulling the in-process of dialling button 52, dial button 52 and take place to rotate and influence user's operation experience for slider 53.

Of course, the positions of the non-circular positioning hole 531 and the positioning column 521 can be interchanged, specifically, one end of the slider 53 can be provided with the positioning column 521 extending upward, and the dial button 52 can be provided with the non-circular positioning hole 531, which is also within the protection scope of the present invention.

In the embodiment where the limiting member 62 is a limiting lever, as shown in fig. 8, 10 and 13, one end of the limiting lever is disposed between the operating member 50 and the other end of the exhaust lever 61, so that the operating member 50 can drive the exhaust lever 61 through one end of the limiting lever, that is, when the operating member 50 drives one end of the limiting lever to move downward, one end of the limiting lever presses the other end of the exhaust lever 61 to move downward, and further one end of the exhaust lever 61 moves upward to jack up the exhaust valve 40. As shown in fig. 15, one end of the limit lever is further configured to limit the operating element 50 in the first position, and when the operating element 50 drives the one end of the limit lever to move downwards, the limit lever rotates to make the operating element 50 and one end of the limit lever move relatively, so that the rotation of the limit lever can not only transmit the power of the operating element 50 to the exhaust lever 61, but also realize the switching of the limit state of the operating element 50, and the arrangement structure of the limit lever, the exhaust lever 61 and the operating element 50 is more compact and the transmission structure is simpler.

In the utility model discloses in further embodiment, as shown in fig. 20 and 21, pot body subassembly 10 can have spacing portion 121 of pot body, the other end of spacing lever can have spacing post 627, spacing post 627 is located the outside of lid body 30 and downwardly extending surpasss the lower border of lid body 30, so that the lower extreme of spacing post 627 can cooperate with spacing portion 121 of pot body, the process of uncapping is rotated at lid subassembly 20 relative to pot body subassembly 10, as shown in fig. 16 and 17, spacing portion 121 of pot body can make the other end of spacing lever shift up, so that operating parts 50 break away from the spacing of the one end of spacing lever, and make discharge valve 40 fall to the closed condition.

Therefore, in the process that the cover body assembly 20 rotates to open the cover relative to the pot body assembly 10, the exhaust valve 40 can be automatically closed, the situation that the exhaust valve 40 is closed due to forgetting operation of a user and cannot be normally pressed in the cooking cavity 101 when cooking next time is caused is avoided, the operation of the user is simpler, the cooking appliance 100 does not need to be additionally provided with an operation structure (such as a reset operation part) for releasing the limit of the limit lever on the operation part 50 and enabling the exhaust valve 40 to be automatically switched to the closed state, and the structure of the cooking appliance 100 is simpler.

Of course, the pot body limiting part 121 can also make the other end of the limiting lever move upwards in the process of rotating and closing the cover of the cover body assembly 20 relative to the pot body assembly 10, which can also make the operating element 50 separate from the limit of one end of the limiting lever and make the exhaust valve 40 fall to the closed state.

Alternatively, the pot body limiting portion 121 may be a limiting boss, as shown in fig. 23, in the process of rotating the cover assembly 20 relative to the pot body assembly 10, since the limiting lever rotates to move the other end of the limiting lever upwards, the limiting boss applies force to the limiting lever from the lower side or the side close to the rotation axis along the horizontal direction, and both can rotate the limiting lever, so as to move the other end of the limiting lever upwards. In other words, the other end of the limit lever can move up under the action of at least one of the upper surface and the side surface of the limit boss, and only the requirement that the operating element 50 can be separated from the limit of the limit lever by the pot body limit part 121 in the process that the cover body assembly 20 rotates relative to the pot body assembly 10 needs to be met.

Alternatively, in the embodiment with the first reset member 54, after the operating member 50 is disengaged from the position limit of the position limit lever during the rotation of the cover assembly 20 relative to the pot assembly 10, the first reset member 54 can drive the operating member 50 to automatically reset to the second position, so that the user can directly drive the operating member 50 to slide along the first direction for pressure relief during the next cooking, which is simpler in operation.

According to some embodiments of the present invention, as shown in fig. 15, the lower portion of one end of the limit lever may be further provided with a concave portion 625, the other end of the exhaust lever 61 may extend into the concave portion 625, and when the operating member 50 is located at the first position, the lower surface of the concave portion 625 may press down the other end of the exhaust lever 61, so that the other end of the exhaust lever 61 moves down, and one end of the exhaust lever 61 may move up to jack up the exhaust valve 40. The other end of the exhaust lever 61 extends into the concave part 625, so that the relative position of the exhaust lever 61 and the limit lever can be limited, the influence on power transmission caused by dislocation is prevented, the structures of the exhaust lever 61 and the limit lever are more compact, and the reduction of the occupied space of the locking mechanism 60 in the vertical direction is facilitated.

In some embodiments of the present invention, as shown in fig. 14 and 15, the locking mechanism 60 may further include a second reset member 63, the second reset member 63 may be connected to the limit lever, and the second reset member 63 may apply a restoring force to the limit lever to move the other end of the limit lever downward. Therefore, when one end of the limit lever is not driven by the driving end 51, the limit lever can move under the action of the restoring force of the second restoring piece 63 to release the downward pressure on the other end of the exhaust lever 61, so that the exhaust lever 61 releases the driving force for driving the exhaust valve 40 to open, or the driving force of the exhaust lever 61 on the exhaust valve 40 can be reduced, so that the exhaust valve 40 can fall to a closed state under the action of self gravity. The second restoring member 63 can reduce the falling resistance of the exhaust valve 40, so that the exhaust valve 40 is closed more smoothly.

Alternatively, one end of the exhaust lever 61 may be moved downward by the exhaust valve 40, and the exhaust lever 61 may be moved downward by another structure to move one end of the exhaust lever 61 downward. For example, in some embodiments, as shown in fig. 3, 9 and 10, the locking mechanism 60 may further include a third restoring member 64, and the third restoring member 64 may apply a restoring force to the exhaust lever 61 to move one end of the exhaust lever 61 downward. Therefore, when the exhaust lever 61 is not limited by the acting force of the positioning lever, the third reset piece 64 can rotate to enable one end of the exhaust lever 61 to move downwards, so that the falling resistance of the exhaust valve 40 is further reduced, the exhaust valve 40 is closed more smoothly, and the sealing effect of the exhaust valve 40 is improved.

For example, in some embodiments, the third restoring member 64 may be a gasket, and one end of the exhaust lever 61 may extend through the gasket and below the exhaust valve 40. When the operating member 50 slides in the first direction, one end of the exhaust lever 61 moves upward, the gasket is deformed, one end of the exhaust lever 61 pushes up the exhaust valve 40 against the gravity of the exhaust valve 40, and when the exhaust lever 61 does not limit the acting force of the positioning lever, one end of the exhaust lever 61 moves downward by the restoring force of the gasket and the gravity of the exhaust valve 40, so that the exhaust valve 40 can fall to a closed state.

According to some embodiments of the present invention, as shown in fig. 24 and 25, the cover assembly 20 may further include a self-locking piece 70, the self-locking piece 70 is installed on the cover body 30, and the self-locking piece 70 is movable along the radial direction of the cover body 30 to be switchable between a locking state and an unlocking state, when the self-locking piece 70 is in the locking state, the self-locking piece 70 is locked with the pot body assembly 10, so that the cover assembly 20 is locked with the pot body assembly 10, the cooking appliance 100 may be pressed to realize pressure cooking, and the self-locking piece 70 is prevented from opening the cover assembly 20 relative to the pot body assembly 10 in the pressure cooking process, thereby preventing dangerous accidents. When self-locking piece 70 is in the unlocked state, self-locking piece 70 is unlocked from pot assembly 10, and lid assembly 20 can be opened by rotating relative to pot assembly 10.

Further, in some embodiments, and with continued reference to fig. 25, the limit lever may have a reset protrusion 626 that extends to the outside of the self-locking element 70. Therefore, when the cover assembly 20 is opened by rotating relative to the pot assembly 10, the self-locking element 70 moves outward along the radial direction of the cover body 30 to push the reset protrusion 626, so that the limit lever rotates, the other end of the limit lever moves upward, one end of the limit lever moves downward to separate the operating element 50 from the limit lever, and the exhaust valve 40 can fall to a closed state. That is, when the cover assembly 20 is opened by rotating relative to the pot assembly 10, the self-locking member 70 is engaged with the reset protrusion 626 to automatically close the exhaust valve 40, so as to prevent the user from forgetting to close the exhaust valve 40 and causing the exhaust valve to be unable to normally press the cooking cavity 101 during the next cooking, and the user operation is simpler.

Of course, in other embodiments, the reset protrusion 626 may also be disposed on the self-locking piece 70 and extend from the self-locking piece 70 to the inner side of the other end of the limit lever, when the cover assembly 20 is opened by rotating relative to the pot assembly 10, the self-locking piece 70 moves outward along the radial direction of the cover body 30, so that the reset protrusion 626 can push the limit lever to rotate outward, so as to separate the operating element 50 from the limit lever.

It should be noted that the cooking device 100 may be provided with only the pot body stopper 121, only the reset protrusion 626, or both the pot body stopper 121 and the reset protrusion 626. That is, when lid assembly 20 is opened by rotating with respect to pan body assembly 10, cooking utensil 100 can be engaged with the limit lever by at least one of pan body limiting portion 121 and reset protrusion 626, so that the limit lever rotates to separate operating member 50 from the limit lever.

According to some embodiments of the present invention, as shown in fig. 2, 20 and 22, the pot body assembly 10 may include: the cooker comprises a base 11, a shell cover 12 and an outer cooker 13, wherein the shell cover 12 is connected with the base 11 to form an outer cooker cavity, the outer cooker 13 can be placed in the outer cooker cavity, and the upper edge of the outer cooker 13 is upwards beyond the cavity opening of the outer cooker cavity.

In the embodiment including the pot body limiting portion 121, as shown in fig. 20-22, the pot body limiting portion 121 may be a limiting boss disposed on the outer shell cover 12, and when the lid assembly 20 is covered on the pot body assembly 10, the limiting lever may be matched with the limiting boss on the adjacent outer shell cover 12, which is beneficial to reducing the size of the limiting lever, and the structural design is more reasonable.

In the embodiment including self-locking member 70, as shown in fig. 2, the upper edge of outer pot 13 may be provided with teeth 131 extending along the circumferential direction thereof, and self-locking member 70 may move along the radial direction of lid body 30 under the stopping action of teeth 131 during the rotation of lid assembly 20 relative to pot assembly 10 between the open lid position and the closed lid position.

When the cover assembly 20 is covered on the pot body assembly 10 to close the opening of the cooking cavity 101, if the exhaust valve 40 is in the closed state, the pressure in the cooking cavity 101 is likely to increase, and further the resistance of the cover assembly 20 covering the pot body assembly 10 is increased, so that the cover assembly 20 is difficult to press down, and the cover assembly 20 is likely to be influenced to rotate to the cover closing position, so that the cover closing of the cover assembly 20 is not smooth. This is particularly true when the temperature inside the cooking chamber 101 is high. For example, in the embodiment of the cooking appliance 100 having the self-locking piece 70 and the float 71, the float 71 is penetrated through the self-locking piece 70, and when the pressure in the cooking chamber 101 is large, the float 71 may be pushed up to prevent the self-locking piece 70 from being switched to the unlocking state in the radial direction of the cover assembly 20. Therefore, if the exhaust valve 40 is in the closed state and the lid assembly 20 is covered on the pot assembly 10, the pressure in the cooking cavity 101 may increase, and the self-locking member 70 may not move, so that the lid assembly 20 cannot rotate to the lid-closed position with respect to the pot assembly 10, and the cooking utensil 100 cannot be closed.

Therefore, when the cover assembly 20 is covered on the pot body assembly 10, the gas in the cooking cavity 101 can be exhausted to the outside through the exhaust valve 40, so that the pressure in the cooking cavity 101 is kept at normal pressure, the cover assembly 20 can be more easily covered on the pot body assembly 10 downwards, and the cover assembly 20 can be more easily rotated to the cover closing position relative to the pot body assembly 10.

Alternatively, in the embodiment where both the pan body limiting portion 121 and the pan body driving portion 122 are provided, the pan body limiting portion 121 and the pan body driving portion 122 may be separately provided as shown in fig. 20-22, and in other embodiments, the pan body limiting portion 121 and the pan body driving portion 122 may be integrated into a boss provided on the outer shell 12, and the boss may not only enable the exhaust valve 40 to be in a state of communicating the cooking cavity 101 with the outside when the cover assembly 20 is in the open position, but also enable the exhaust valve 40 to be reset to the closed state during the rotation of the cover assembly 20 relative to the pan body assembly 10.

In some embodiments of the present invention, as shown in fig. 1-3, the cover body 30 may include: the operating device comprises a surface cover 31 and an inner cover 32, wherein the surface cover 31 has a guide through hole 311 and a relief hole 312, the operating element 50 can be inserted into the guide through hole 311, the upper part of the operating element 50 protrudes out of the upper surface of the surface cover 31 so as to be convenient for a user to operate the operating element 50, and the guide through hole 311 can guide the operating element 50 so that the operating element 50 can slide in the guide through hole 311 along a first direction and a second direction. The inner cover 32 is positioned at a lower side of the face cover 31, the exhaust lever 61 and the limit lever may be positioned between the face cover 31 and the inner cover 32, and the exhaust lever 61 and the limit lever may be connected to at least one of the face cover 31 and the inner cover 32. For example, in some embodiments, as shown in fig. 9-11, the exhaust lever 61 may be rotatably connected to the face cover 31 by a fastener 65, as shown in fig. 12, the limit lever may be rotatably connected to the inner cover 32 by a rotating shaft, and the connection structure is simple and easy to disassemble and assemble. The inner lid 32 may be provided with a vent valve core 321, and the vent valve core 321 has a vent hole, the vent valve 40 may be sleeved on the vent valve core 321, and the vent valve 40 has a sealing portion for blocking the vent hole, and an upper portion of the vent valve 40 may upwardly pass through the escape hole 312, so that when the vent valve 40 is in the first open state or the second open state, the gas in the cooking cavity 101 may be exhausted to the outside through the vent hole and the vent valve 40.

In the embodiment that includes the third returning member 64 and the third returning member 64 is a sealing gasket, as shown in fig. 3, a side wall of the avoiding hole 312 may be provided with a mounting opening, so that one end of the exhaust lever 61 may pass through the mounting opening and extend to the lower side of the exhaust valve 40, the sealing gasket may be provided between an edge of the mounting opening and one end of the exhaust lever 61, and the sealing gasket may be used not only for returning the exhaust lever 61 but also for sealing a gap between the edge of the mounting opening and the exhaust lever 61.

As shown in fig. 1-3, cooking device 100 includes a body assembly 10 and a cover assembly 20, wherein the cover assembly 20 can be covered on the body assembly 10 downward, and the cover assembly 20 can rotate between an open position and a closed position with respect to the body assembly 10 after covering the body assembly 10. As shown in fig. 3 and 4, the cover assembly 20 includes a cover body 30, an exhaust valve 40, an operating member 50, a locking mechanism 60 and a first restoring member 54, the locking mechanism 60 includes an exhaust lever 61, a limiting member 62, a second restoring member 63 and a third restoring member 64, the limiting member 62 is a limiting lever, and the pot body assembly 10 is provided with a pot body limiting portion 121 and a pot body driving portion 122. As shown in fig. 5 to 11, one end of the exhaust lever 61 is located below the exhaust valve 40, one end of the limit lever is located between the driving end 51 of the operating element 50 and the other end of the exhaust lever 61, the first restoring member 54 is connected to the operating element 50 and applies a restoring force in the second direction to the operating element 50, the second restoring member 63 is connected to the limit lever and applies a restoring force to the limit lever to move the other end of the limit lever downward, and the third restoring member 64 is connected to the exhaust lever 61 and applies a restoring force to the exhaust lever 61 to move the one end of the exhaust lever 61 downward.

In the process, the operating member 50 is in the second position.

After the cover assembly 20 is rotated from the cover opening position to the cover closing position, as shown in fig. 12 and 13, the other end of the limit lever is disengaged from the cooker body driving part 122 and the cooker body limit part 121, the other end of the limit lever moves downwards under the action of the second reset piece 63, one end of the exhaust lever 61 moves downwards under the action of the third reset piece 64, the exhaust valve 40 is in a closed state under the action of self gravity, so that the cooking cavity 101 is isolated from the outside, and the cooking appliance 100 can normally generate pressure to cook under pressure.

After cooking, the user can push the operation element 50 to slide the operation element 50 along the first direction as shown in fig. 13, the driving inclined plane 511 of the driving end 51 abuts against the matching inclined plane 621 of the limit lever, so that one end of the limit lever moves downwards and presses the other end of the exhaust lever 61 downwards, and one end of the exhaust lever 61 moves upwards to jack the exhaust valve 40. When the driving end 51 moves in the first direction to pass over the limiting protrusion 623 and move against the pressed surface 622, as shown in fig. 14 and 15, the exhaust valve 40 is in the first open state, the air in the cooking cavity 101 can be exhausted to the outside through the exhaust valve 40 to realize pressure relief, and the limiting protrusion 623 limits the operating element 50 to slide in the second direction, at this time, the user can remove the external force on the operating element 50, the operating element 50 is locked at the first position, and the exhaust valve 40 can continuously relieve the pressure.

After the pressure relief is completed, the user can push the operating element 50 to slide along the second direction, so that the driving end 51 is separated from the limit of the limit protrusion 623 and returns to the second position. Or the user can directly control the cover assembly 20 to rotate from the cover closing position to the cover opening position without operating the operating element 50, and during the rotation process, as shown in fig. 16 and 17, the other end of the limit lever abuts against the pot body limiting part 121, so that the other end of the limit lever further moves upwards, one end of the limit lever further moves downwards, so that the limit protrusion 623 is disengaged from the driving end 51, the limit of the limit lever on the operating element 50 is released, and the operating element 50 can return to the second position shown in fig. 12 and 13 under the action of the first resetting element 54. When the cover assembly 20 continues to rotate until the limit lever is disengaged from the pot body limit part 121, as shown in fig. 12 and 13, the other end of the limit lever moves downwards under the action of the second reset piece 63, one end of the exhaust lever 61 moves downwards under the action of the third reset piece 64, and the exhaust valve 40 falls to a closed state. Therefore, when the cooking is performed next time, the operating member 50 is at the second position, the limit lever is disengaged from the pot body limit part 121 and the pot body driving part 122, the exhaust valve 40 is in the closed state, and the cooking utensil 100 can be normally lifted and pressed for cooking.
