The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. In the description of the present invention, "the first feature" and "the second feature" may include one or more of the features, and "a plurality" means two or more.

A cooking appliance 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a cooking appliance 100 according to an embodiment of the present invention may include: a pot body assembly 10 and a pot cover assembly 20.

Specifically, the lid assembly 20 can be covered on the body assembly 10, and the lid assembly 20 cooperates with the body assembly 10 to form the cooking cavity 101. Lid assembly 20 is pivotable relative to body assembly 10 between an open position and a closed position, it being understood that "open lid" is not generally understood to mean opening lid assembly 20 to open the mouth of cooking chamber 101, and "closed lid" is not generally understood to mean closing lid assembly 20 to close the mouth of cooking chamber 101. However, when the lid assembly 20 is in the lid-closing position, the lid assembly 20 is locked with the body assembly 10, and the lid assembly 20 cannot be separated from the body assembly 10, and when the lid assembly 20 is in the lid-opening position, the lid assembly 20 is unlocked from the body assembly 10, and the lid assembly 20 can move relative to the body assembly 10 to separate from the body assembly 10.

As shown in fig. 3 to 8, the pot cover assembly 20 may include: a pot cover body 30, a vent valve 40 and a locking mechanism 60. As shown in fig. 5 to 11, the exhaust valve 40 is disposed on the lid body 30, and the exhaust valve 40 can be opened and closed, when the exhaust valve 40 is opened, the cooking cavity 101 is communicated with the outside, so that the pressure in the cooking cavity 101 is normal pressure or tends to normal pressure, when the exhaust valve 40 is closed, the cooking cavity 101 is isolated from the outside, so that the pressure in the cooking cavity 101 can be normally increased or decreased to realize positive pressure or negative pressure cooking, and the cooking device 100 can normally work.

The applicant researches and discovers that 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 closed, the pressure in the cooking cavity 101 is increased, and further, the resistance of the cover assembly 20 covering on the pot body assembly 10 is increased, so that the cover assembly 20 is difficult to press down, and the cover assembly 20 is easy to rotate to the cover closing position, and 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 in which the cooking appliance 100 includes the self-locking piece 70 and the float 71, the self-locking piece 70 is movable in the radial direction of the pot cover body 30 to be switchable between a locked state of being locked with the pot body assembly 10 and an unlocked state of being unlocked with the pot body assembly 10, and the float 71 is disposed through the self-locking piece 70. When the pressure in the cooking chamber 101 is large, the float 71 may be pushed up to prevent the self-locking member 70 from being switched to the unlocking state in the radial direction of the lid assembly 20. Therefore, if the exhaust valve 40 is closed when the lid assembly 20 is placed on the pot assembly 10, that is, if the exhaust valve 40 is closed when the lid assembly 20 is in the open position, the pressure in the cooking cavity 101 may increase, and the float 71 may float upward to disable the self-locking member 70 from moving, so that the lid assembly 20 may not rotate to the closed position with respect to the pot assembly 10, and the cooking utensil 100 may not be closed.

Therefore, in the present invention, the cooking appliance 100 is provided with the locking mechanism 60, as shown in fig. 3 and 20 to 21, the locking mechanism 60 may be connected with at least one of the lid body 30 and the pot body assembly 10, and the locking mechanism 60 is configured to limit the exhaust valve 40 to a state of communicating the cooking chamber 101 with the outside when the lid assembly 20 is in the open-lid position.

From this, lid 20 covers the in-process of locating pot body subassembly 10 at pot cover subassembly 20, pot cover subassembly 20 is in the position of uncapping, and culinary art chamber 101 and external intercommunication, culinary art chamber 101 internal pressure is ordinary pressure or pressure is lower, pressure in the culinary art chamber 101 closes and closes the lid process to pot cover subassembly 20 lid and does not have the influence, pot body subassembly 10 is easier to locate to the lower cover of pot cover subassembly 20, and pot cover subassembly 20 is little to closing the resistance that covers between position rotation in-process pot cover subassembly 20 and the pot body subassembly 10, pot cover subassembly 20 rotates more easily, it is more smooth and easy to close the lid.

According to the cooking utensil 100 of the embodiment of the invention, the exhaust valve 40 is limited to the state of communicating the cooking cavity 101 with the outside when the pot cover assembly 20 is in the open position through the locking mechanism 60, so that the resistance of the pot cover assembly 20 covering the pot body assembly 10 and the resistance of the pot cover assembly 20 rotating relative to the pot body assembly 10 to the closed position can be effectively reduced, the pot cover assembly 20 is easier to cover and close, the operation of a user is more labor-saving, and the pot cover assembly 20 is beneficial to ensuring the cover to be closed in place.

According to some embodiments of the present invention, as shown in fig. 20, the locking mechanism 60 may include: pot body drive portion 122 and locking main part 601, wherein, pot body drive portion 122 is located pot body subassembly 10, and locking main part 601 is located pot cover body 30, and when pot cover subassembly 20 was in the position of uncapping, pot body drive portion 122 can drive locking main part 601 motion to make locking main part 601 can open discharge valve 40. The fitting structure of the pot body driving part 122 and the locking body 601 is simple, and the driving force of the pot body driving part 122 to the locking body 601 is strong and stable.

In some embodiments of the present invention, as shown in fig. 3 and 4, the locking body 601 may include: a first exhaust lever 61a and a first transmission 62 a. As shown in fig. 7-11, the first exhaust lever 61a can be rotatably connected to the pot cover body 30, one end of the first exhaust lever 61a can be used for driving the exhaust valve 40, and when the first transmission member 62a abuts against the pot body driving part 122, the first transmission member 62a can drive the other end of the first exhaust lever 61a to move downwards, so that one end of the first exhaust lever 61a moves upwards to jack up the exhaust valve 40. Thus, the first exhaust lever 61a and the first transmission member 62a cooperate to convert the relative movement of the lid assembly 20 and the pot assembly 10 into the movement of the exhaust valve 40 in the up-and-down direction.

In some embodiments of the present invention, as shown in fig. 4 and 6, the first transmission member 62a may be a transmission lever, and the transmission lever is rotatably connected to the lid body 30, as shown in fig. 8, 10 and 13, one end of the transmission lever is a transmission driving end, and the transmission driving end may be located above the other end of the first exhaust lever 61a, so that when the lid assembly 20 is in the lid opening position, the other end of the transmission lever may abut against the lid body driving portion 122, and the other end of the transmission lever moves upward to move the transmission driving end downward, so that the transmission driving end may apply a downward pressure to the other end of the first exhaust lever 61a to move the other end of the first exhaust lever 61a downward, and move one end of the first exhaust lever 61a upward to jack the exhaust valve 40. The lever structure formed by the matching of the transmission lever and the first exhaust lever 61a realizes the driving of the exhaust valve 40, the transmission is more labor-saving, and the exhaust valve 40 is driven to be opened more sensitively.

Alternatively, the pot body driving part 122 may be a driving boss, as shown in fig. 24, when the lid assembly 20 is in the lid opening position, since the transmission lever rotates to move up the other end thereof, the driving boss applies a force to the transmission lever from the lower side or a side close to the rotation axis in the horizontal direction, and both the driving boss and the transmission lever can rotate to move up the other end of the transmission lever, and the transmission driving end of the transmission lever moves down to press down the other end of the first exhaust lever 61a, so that one end of the first exhaust lever 61a tilts up to jack up the exhaust valve 40. In other words, at least one of the side surface and the upper surface of the driving boss may abut against the other end of the transmission lever to apply an upward driving force to the other end of the transmission lever, and it is only necessary to satisfy a requirement that the driving boss may cooperate with the locking body 601 to open the exhaust valve 40 when the lid assembly 20 is in the lid opening position.

Optionally, in an embodiment of the present invention, when the lid assembly 20 is covered on the pot assembly 10, the lid assembly 20 is in the open position, and the upper surface of the driving boss can abut against the other end of the transmission lever to drive the exhaust valve 40 to open, so that the lid assembly 20 can be more easily closed and opened. When the lid assembly 20 is in the closed position, the other end of the transmission lever is disengaged from the driving boss, so that the exhaust valve 40 can be closed, and the cooking utensil 100 can be normally lifted and pressed to facilitate cooking. In the process that the pot cover assembly 20 rotates from the cover closing position to the cover opening position, the side face of the driving boss can abut against the other end of the transmission lever to drive the exhaust valve 40 to be opened, the transmission lever and the driving boss move smoothly relatively, and the pot cover assembly 20 is easy to open.

Alternatively, when the first exhaust lever 61a is not acted by the transmission lever, one end of the first exhaust lever 61a may move downward under the action of the exhaust valve 40, and the first exhaust lever 61a may also move under the action of its own weight or other structures to move the one end of the first exhaust lever 61a downward, so as to reset the first exhaust lever 61 a. For example, in some embodiments, as shown in fig. 3, 9, and 10, the locking mechanism 60 may further include a seal 64, and the seal 64 may apply a restoring force to the first exhaust lever 61a that moves one end of the first exhaust lever 61a downward. Therefore, when the first exhaust lever 61a is not acted by the action force of the transmission lever, the first exhaust lever 61a can rotate under the action of the sealing element 64 to enable one end of the first exhaust lever 61a to move downwards, so that the falling resistance of the exhaust valve 40 is 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 seal 64 may be a gasket through which an end of the first exhaust lever 61a may extend below the exhaust valve 40. When the transmission lever abuts against the pot body driving part 122, one end of the first exhaust lever 61a moves upwards, the sealing gasket deforms, one end of the first exhaust lever 61a overcomes the gravity of the exhaust valve 40 to jack the exhaust valve 40 upwards, and when the first exhaust lever 61a is not under the action of the transmission lever, one end of the first exhaust lever 61a moves downwards under the action of the restoring force of the sealing gasket and the gravity of the exhaust valve 40, so that the exhaust valve 40 can fall to a closed state.

Optionally, when the transmission lever does not abut against the pan body driving part 122, the other end of the transmission lever may move downward under the action of the first exhaust lever 61a, and the transmission lever may also move under the action of its own gravity or other structures to move the other end of the transmission lever downward, so as to achieve the reset of the transmission lever. For example, in some embodiments, as shown in fig. 14 and 15, the locking mechanism 60 may further include a second restoring member 63, the second restoring member 63 may be connected to the actuating lever, and the second restoring member 63 may apply a restoring force to the actuating lever to move the other end of the actuating lever downward. Therefore, when the transmission lever is not abutted against the pot body driving part 122, the transmission 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 first exhaust lever 61a, so that the first exhaust lever 61a releases the driving force for driving the exhaust valve 40 to be opened, or the driving force of the first exhaust lever 61a 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 reset piece 63 can reduce the falling resistance of the exhaust valve 40, so that the exhaust valve 40 is closed more smoothly, and the sealing performance is better.

Alternatively, the present invention does not specifically limit the specific structure of the second returning member 63, for example, in some embodiments, as shown in fig. 14, the second returning member 63 may be a coil spring, one end of the coil spring may be connected to the transmission lever, and the other end of the coil spring may be connected to the lid body 30. When the other end of the transmission lever moves up under the action of the pan body driving part 122, the spiral spring is compressed and deformed, and when the transmission lever is not acted by the pan body driving part 122, the restoring force of the spiral spring enables the other end of the transmission lever to move down and reset.

For example, in other embodiments, as shown in fig. 27 and 28, the pot lid body 30 may include an inner lid 32 and a face lid 31 provided on an outer side of the inner lid 32, the locking body 601 is provided on the inner lid 32, the second restoring member 63 is connected to the transmission lever, and the second restoring member 63 extends toward a top wall of the face lid 31. Specifically, the second reset piece 63 is a spring plate, one end of the spring plate is connected to the transmission lever, and the joint of the spring plate and the transmission lever is located on one side of the rotation axis of the transmission lever, which is close to the other end of the transmission lever. When the other end of the transmission lever moves up under the action of the pan body driving part 122, the elastic sheet can abut against the top surface cover 31 and elastically deform, so that the distance between the other end of the elastic sheet and the transmission lever along the up-down direction is reduced, and when the transmission lever is not under the action of the pan body driving part 122, the restoring force of the elastic sheet enables the other end of the transmission lever to move down for resetting. Alternatively, the resilient tab may be connected to the actuating lever or may be integrally formed with the actuating lever.

Alternatively, in the present invention, the other end of the transmission lever may be directly engaged with the pan body driving part 122 or indirectly engaged with the pan body driving part 122.

For example, in some embodiments, as shown in fig. 21 and 24, the other end of the transmission lever extends downward beyond the lower edge of the lid body 30 to directly abut against the lid body driving part 122. In other embodiments, as shown in fig. 27 and 28, the locking body 601 may further include a first transmission push rod 65a, the first transmission push rod 65a may be connected to the lid body 30, and the first transmission push rod 65a may be movable up and down with respect to the lid body 30. The upper end of the first transmission top rod 65a is positioned below the other end of the transmission lever, and the lower end of the first transmission top rod 65a can be matched with the pot body driving part 122. When the lower end of the first transmission top rod 65a abuts against the pot body driving part 122, the first transmission top rod 65a can move upwards to enable the upper end of the first transmission top rod 65a to push the other end of the transmission lever to move upwards, and further the transmission driving end of the transmission lever moves downwards and presses the other end of the first exhaust lever to enable one end of the first exhaust lever to tilt to open the exhaust valve 40.

Optionally, the lower surface of the other end of the transmission lever may be an inclined surface extending downward relative to the vertical direction and inclined toward the direction away from the first exhaust lever 61a, the upper end of the first transmission ejector rod 65a may be a spherical surface, the spherical surface and the inclined surface cooperate to convert the movement of the first transmission ejector rod 65a in the up-down direction into the rotation of the transmission lever, the driving resistance is smaller, and the structural design is more reasonable.

Optionally, when the first transmission top rod 65a is disengaged from the pan body driving part 122, the first transmission top rod 65a may move downwards to reset under the action of its own weight or a transmission lever, and the first transmission top rod 65a may also move downwards to reset under the action of other structures. In some embodiments, as shown in fig. 27 and 28, the locking body 601 may further include a first push rod restoring member 66a, the first push rod restoring member 66a is connected to the first transmission push rod 65a, and the first push rod restoring member 66a may apply a driving force to the first transmission push rod 65a to move the first transmission push rod 65a downward. Therefore, when the first transmission top rod 65a is disengaged from the pan body driving part 122, the first transmission top rod 65a can be reset under the driving of the first top rod resetting piece 66a, and the resetting effect of the first transmission top rod 65a is better.

According to further embodiments of the present invention, as shown in fig. 29-32, the locking body 601 may include: a second exhaust lever 61b, a second transmission post rod 65b and a second transmission piece 62 b. Wherein, the second exhaust lever 61b is rotatably connected with the pot cover body 30, and one end of the second exhaust lever 61b is used for opening the exhaust valve 40. The second driving push rod 65b can be connected with the pot cover body 30, and the second driving push rod 65b can move up and down relative to the pot cover body 30, and the upper end of the second driving push rod 65b is provided with a driving inclined plane 651. The second transmission member 62b is connected to the lid body 30, and the second transmission member 62b can move in the horizontal direction relative to the lid body 30, and one end of the second transmission member 62b has a transmission mating surface 627.

When the pot cover assembly 20 is covered on the pot body assembly 10, the pot cover assembly 20 is in the cover opening position, the upper surface of the pot body driving part 122 can abut against the lower end of the second transmission ejector rod 65b and upwards push the second transmission ejector rod 65b to drive the second transmission ejector rod 65b to move upwards, and then the transmission inclined surface 651 can be matched with the transmission matching surface 627 to enable the second transmission piece 62b to horizontally move, so that the other end of the second transmission piece 62b can apply downward pressure to the other end of the second exhaust lever 61b, one end of the second exhaust lever 61b can be tilted to enable the exhaust valve 40 to move upwards and open, and the pot cover assembly 20 is covered on the pot body assembly 10 more easily. The locking body 601 is compact in structure and requires a small operation space in the up-down direction, which is advantageous for making the structure of the lid assembly 20 more compact.

In the present invention, the transmission inclined surface 651 and the transmission matching surface 627 extend obliquely with respect to the vertical direction, so that the movement of the second transmission top rod 65b in the up-down direction is converted into the movement of the second transmission member 62b in the horizontal direction, and the transmission resistance between the transmission inclined surface 651 and the transmission matching surface 627 is favorably reduced.

Further, as shown in fig. 31 and 32, the other end of the second transmission piece 62b is provided with a driving protrusion 628, the driving protrusion 628 protrudes toward the second exhaust lever 61b, and the driving protrusion 628 is provided with a protrusion slope 629, when the second transmission jack 65b is separated from the pot body driving part 122, the driving protrusion 628 is at one side of the second exhaust lever 61b in the horizontal direction, and the protrusion slope 629 extends obliquely downward with respect to the vertical direction and in a direction away from the second exhaust lever 61 b.

In the process that the second transmission top rod 65b moves upwards under the action of the pot body driving part 122, the driving protrusion 628 moves towards the direction close to the second exhaust lever 61b along the horizontal direction, and in the process, the protrusion inclined plane 629 abuts against the other end of the second exhaust lever 61b and moves relatively along the horizontal direction to abut against the other end of the second exhaust lever 61b, so that the other end of the second exhaust lever 61b is driven to move downwards. The second transmission member 62b applies downward pressure to the other end of the second exhaust lever 61b through the protrusion inclined surface 629, which is beneficial to reduce the resistance of the relative movement between the second transmission member 62b and the second exhaust lever 61b, so that the movement is smoother.

It should be noted that, in the process of moving the driving protrusion 628 in the direction approaching the second exhaust lever 61b along the horizontal direction, the driving protrusion 628 may move to above the other end of the second exhaust lever 61b as a whole as shown in fig. 32, and the driving protrusion 628 may also move to a position where the middle of the protrusion inclined plane 629 abuts against the other end of the second exhaust lever 61b, that is, a part of the driving protrusion 628 moves to above the other end of the second exhaust lever 61b, which is within the protection scope of the present invention.

Alternatively, the inclined directions of the transmission inclined surface 651 and the transmission mating surface 627 can be flexibly set according to actual conditions. For example, in some embodiments, as shown in fig. 31 and 32, the other end of the second transmission member 62b has a driving protrusion 628 extending downward, the driving protrusion 628 is located on a side of the second exhaust lever 61b away from the pot body driving portion 122 when disengaged from the second exhaust lever 61b, the transmission engagement surface 627 extends downward relative to the vertical direction and is inclined in a direction away from the second exhaust lever 61b, and the transmission inclined surface 651 is inclined in the same direction as the transmission engagement surface 627. When the second driving rod 65b moves up against the pan body driving part 122, the driving inclined surface 651 cooperates with the driving mating surface 627 to move the second driving member 62b away from the second exhaust lever 61b, so that the driving protrusion 628 moves above the second exhaust lever 61b and presses down the other end of the second exhaust lever 61b, so that the exhaust valve 40 is opened at one end of the second exhaust lever 61 b.

In other embodiments, the other end of the second transmission member 62b has a driving protrusion 628 extending downward, the driving protrusion 628 is located on a side of the second exhaust lever 61b close to the pot body driving portion 122 when disengaged from the second exhaust lever 61b, the transmission engagement surface 627 extends downward relative to the vertical direction and slants toward the second exhaust lever 61b, and the transmission inclined surface 651 is inclined in the same direction as the transmission engagement surface 627. When the second driving rod 65b moves up against the pan body driving part 122, the driving inclined surface 651 cooperates with the driving mating surface 627 to move the second driving member 62b toward the second exhaust lever 61b, so that the driving protrusion 628 moves above the second exhaust lever 61b and presses down the other end of the second exhaust lever 61b, so that the exhaust valve 40 is opened at one end of the second exhaust lever 61 b.

Alternatively, in the present invention, the second transmission top rod 65b can be moved downwards to be reset under the action of its own weight or the second transmission piece 62b, and the second transmission top rod 65b can also be reset under the action of other structures. Referring to fig. 30, the locking body 601 may further include a second push rod resetting member 66b, the second push rod resetting member 66b is connected to the second transmission push rod 65b, and can apply a driving force to the second transmission push rod 65b to move the second transmission push rod 65b downward, so that when the second transmission push rod 65b is disengaged from the pot body driving portion 122, the second transmission push rod 65b can be reset under the action of the second push rod resetting member 66b, the second transmission push rod 65b is better in resetting effect, and the locking is not easy to occur.

Alternatively, in the present invention, the second transmission member 62b may be reset by the horizontal movement under the self-gravity or the second exhaust lever 61b, and the second transmission member 62b may also be reset by other structures. Referring to fig. 31 and 32, the locking body 601 may further include a third returning member 67, the third returning member 67 may be connected to the second transmission member 62b, and when the second transmission top rod 65b is separated from the pot body driving part 122, the third returning member 67 may drive the second transmission member 62b to horizontally move, so that the other end of the second transmission member 62b is disengaged from the other end of the second exhaust lever 61b, so that one end of the second exhaust lever 61b may move downward to be returned, the exhaust valve 40 may be closed, the second transmission member 62b has a good returning effect, and is not easily jammed. It can be understood that, here, the moving direction of the third returning member 67 for driving the second transmission member 62b to horizontally move and return is opposite to the moving direction of the second transmission top rod 65b for driving the second transmission member 62b to horizontally move.

According to still other embodiments of the present invention, the locking body 601 may include an exhaust push rod and a third transmission member, one end of the exhaust push rod may be located below the exhaust valve 40 to open the exhaust valve 40, the third transmission member may be connected to the pot cover body 30, and the other end of the exhaust push rod may be connected to the third transmission member so that the exhaust push rod and the third transmission member may move synchronously.

When pot body subassembly 10 was located in pot body subassembly 20 lid, pot body subassembly 20 was in the position of uncapping, and the upper surface of pot body drive division 122 can offset with the third driving medium to jack up the third driving medium upwards, with drive third driving medium jacket, the exhaust ejector pin can shift up along with the third driving medium is synchronous, and drive discharge valve 40 opens, and it is easier that pot body subassembly 10 is fitted to pot body subassembly 20 lid.

Alternatively, in the present invention, the exhaust ejector rod and the third transmission member may be an integral piece, so that the structure of the locking main body 601 is simpler, and the exhaust ejector rod and the third transmission member may also be separate pieces connected to each other, which is convenient for processing and assembling.

According to some embodiments of the present invention, as shown in fig. 2, 20 and 22, pan body assembly 10 may include: base 11, outer clamshell 12 and outer pot 13, outer clamshell 12 links to each other in order to form outer pot chamber with base 11, and outer pot 13 can arrange outer pot intracavity in, and outer clamshell 12 can be located to pot body drive division 122, and when pot body subassembly 10 was located to pot lid subassembly 20 lid, the transmission lever can cooperate with pot body drive division 122 on the adjacent outer clamshell 12, is favorable to reducing the size of transmission lever, and structural design is more reasonable.

According to a further embodiment of the present invention, as shown in fig. 3 to 8, the lid assembly 20 may further include an operating member 50, as shown in fig. 12 to 13, the operating member 50 may be connected to the lid body 30, and the operating member 50 may be slidable in the first direction and the second direction. The operating member 50 is slidable in a first direction to a first position as shown in fig. 14 and 15, and the sliding of the operating member 50 to the first position causes the locking body 601 to drive the discharge valve 40 to a first open state. The operating member 50 is slidable in the second direction to a second position as shown in fig. 12 and 13, and the exhaust valve 40 can be in a closed state when the operating member 50 is slid to the second position.

Therefore, the exhaust valve 40 can be opened to realize pressure relief by sliding the operating member 50 in different directions, the exhaust valve 40 can be closed to facilitate cooking, the opening and closing control of the exhaust valve 40 is simple, the operating member 50 is simple in structure, and the situation that a user does not know which operating member 50 needs to be operated to realize the opening or closing of the exhaust valve 40 due to the fact that the number of the operating members 50 is too large is avoided.

The opening and closing of the exhaust valve 40 can be realized not only by the cooperation of the pot body driving part 122 and the locking main body 601, but also by the cooperation of the operating part 50 and the locking main body 601, for example, when cooking is completed, a user can perform pressure relief by the operation of the operating part 50, and when the pot cover assembly 20 is covered on the pot body assembly 10, the exhaust valve 40 can be driven to open by the pot body driving part 122, so that the use is more convenient.

It will be appreciated that for ease of understanding, the operating member 50 is shown in the second position in solid lines in FIG. 13, and the operating member 50 is shown in the first position in dashed lines in FIG. 13. It should be noted that during the sliding of the operating member 50 in the first direction and the second direction, the sliding track of the operating member 50 may be a straight line, an arc line or a combination of the two, and the sliding track of the operating member 50 in the first direction and the sliding track of the operating member 50 in the second direction may or may not be completely overlapped. In addition, the sliding direction of the operating element 50 relative to the lid body 30 can be flexibly set according to actual conditions, and only the requirement that the state switching of the exhaust valve 40 can be realized by sliding the operating element 50 along the first direction and the second direction is required to be met.

For example, in some embodiments, as shown in fig. 1 and 2, the operating member 50 is slidable in a direction perpendicular to the radial direction of the lid body 30 to achieve sliding in the first direction and the second direction; in other embodiments, as shown in fig. 3, 12 and 13, the operation member 50 is slidable along the edge of the lid body 30 toward the center of the lid body 30 to realize sliding along the first direction and the second direction, so that the user can apply force more easily during sliding of the operation member 50, and the operation is easier.

Further, as shown in fig. 14 and 15, the lock main body 601 is also configured to be able to lock the operating member 50 in the first position. That is, even if the external force for driving the operating member 50 to slide in the first direction is removed, the operating member 50 can be maintained at the first position by the locking body 601, and the exhaust valve 40 can be maintained at the first open state, so that the pressure of the cooking appliance 100 can be continuously released. In the pressure relief process, the user does not need to manually operate the operating part 50 for a long time to maintain the first position, the use is simpler, the user can be effectively prevented from being scalded by hot steam in the pressure relief process, and the use is safer.

According to some embodiments of the present invention, as shown in fig. 4, 14 and 15, the locking body 601 may have a buckling portion 624, the operating element 50 may have a buckling and matching portion 513, and when the operating element 50 is in the first position, the buckling portion 624 and the buckling and matching portion 513 may be buckled to limit the operating element 50, and the limiting structure of the operating element 50 is simple.

Further, as shown in fig. 13 and 15, the buckling part 624 may be a buckling protrusion protruding toward the operation part 50, and the buckling matching part 513 may be a matching protrusion protruding toward the buckling part 624, and in the process that the operation part 50 slides in the first direction, the matching protrusion may cross the buckling protrusion from one side of the buckling protrusion shown in fig. 13 and move to the other side of the buckling protrusion shown in fig. 15, so as to achieve buckling, and the buckling structure of the buckling protrusion and the matching protrusion is simple, and the position limitation is stable.

When it is desired to release the engagement of the engaging protrusion and the mating protrusion, the operating member 50 may be manually controlled to slide in the second direction so that the mating protrusion passes over the engaging protrusion from the other side of the engaging protrusion as shown in fig. 15 and moves to the one side of the engaging protrusion as shown in fig. 13. Certainly, the buckling protrusion and the matching protrusion can be driven by other structures to realize automatic unlocking, so that the situation that the user forgets to drive the operating part 50 to reset to the second position to cause the abnormal pressure rise of the cooking cavity 101 is prevented.

In the embodiment where the locking body 601 includes the first exhaust lever 61a and the first transmission member 62a, the first transmission member 62a may be configured to limit the operation member 50 in the first position to prevent the operation member 50 from sliding to the second position, and the exhaust valve 40 may be maintained in the first open state to achieve continuous pressure relief.

Alternatively, as shown in fig. 4 and 6, the lid assembly 20 may further include a first returning member 54, the first returning member 54 is connected to the operating member 50, and the first returning member 54 is configured to apply a restoring force in the second direction to the operating member 50. Therefore, when the operating element 50 is not limited by the locking main body 601, the first reset piece 54 can drive the operating element 50 to automatically reset without manually driving the operating element 50 to reset by a user, or the force required by the user to drive the operating element 50 to reset to the second position can be reduced, so that the user operation is more labor-saving.

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 operation member 50 is in the intermediate position, the operation member 50 may cooperate with the locking body 601 such that the discharge valve 40 is in the second open state in which the cooking chamber 101 communicates with the outside, and when the operation member 50 is in the intermediate position, it is not restricted by the locking body 601.

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 operation element 50 slides back and forth between the second position and the middle position to realize the staged pressure relief, and the pressure relief mode is more diversified.

In some embodiments of the present invention, as shown in fig. 20 and 21, the pot body assembly 10 may have a pot body limiting portion 121, and during the lid opening process of the pot cover assembly 20 rotating relative to the pot body assembly 10, the locking main body 601 may cooperate with the pot body limiting portion 121 to disengage the operating element 50 from the locking of the locking main body 601 and allow the exhaust valve 40 to fall to the closed position, so as to achieve the automatic closing of the exhaust valve 40, prevent the user from forgetting to operate to close the exhaust valve 40 and causing the exhaust valve 101 to be unable to normally rise when cooking next time, the user operation is simpler, and the cooking appliance 100 does not need to additionally provide an operation structure (e.g., a reset operating element) for releasing the limit of the transmission lever on the operating element 50 and automatically switching the exhaust valve 40 to the closed state, so that the structure of.

For example, in the embodiment shown in fig. 14-21, the other end of the transmission lever can be engaged with the pan body limiting part 121, and during the process of opening the lid by rotating the lid assembly 20 relative to the pan body assembly 10, as shown in fig. 16 and 17, the pan body limiting part 121 can move the other end of the transmission lever upwards to disengage the operation member 50 from the limit of the transmission driving end of the transmission lever and to allow the exhaust valve 40 to fall to the closed state.

Of course, the pot body limiting part 121 can also move the other end of the transmission lever upwards in the process of rotating the pot cover assembly 20 relative to the pot body assembly 10, which can also make the operating piece 50 separate from the limit of the transmission driving end of the transmission 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. 24, in the process of rotating the pot cover assembly 20 relative to the pot body assembly 10, since the transmission lever rotates to move the other end of the transmission lever upwards, the limiting boss applies a force to the transmission lever from the lower side or the side close to the rotation axis along the horizontal direction, and both the limiting boss and the transmission lever can rotate to move the other end of the transmission lever upwards. In other words, the other end of the transmission lever can move upwards 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 transmission lever by the pot body limit part 121 in the process that the pot cover 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 limit position of the transmission lever during the rotation of the pot cover assembly 20 relative to the pot body 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.

Alternatively, in the embodiment where the pan body limiting portion 121 and the pan body driving portion 122 are provided at the same time, 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 as a boss provided on the outer housing 12 as shown in fig. 23, and the boss may enable the exhaust valve 40 to be in a state of communicating the cooking cavity 101 with the outside when the lid assembly 20 is in the open-lid position, and may enable the exhaust valve 40 to be reset to the closed state during the rotation of the lid assembly 20 relative to the pan body assembly 10.

According to a further embodiment of the present invention, as shown in fig. 13, the operating member 50 may have a driving end 51 extending to above the transmission lever, the driving end 51 may be provided with a driving inclined surface 511 and a stopper surface 512, the driving inclined surface 511 is provided at a front end of the driving end 51 in the first direction, and the driving inclined surface 511 extends obliquely forward and upward, and the stopper surface 512 is provided at a rear side of the driving inclined surface 511 in the first direction. The actuating lever may have a fitting slope 621, a pressure receiving surface 622, and a stopper protrusion 623, wherein the fitting slope 621 extends forward and upward obliquely in the first direction, the pressure receiving surface 622 is located forward of the fitting slope 621 in the first direction, and the stopper protrusion 623 is located between the fitting slope 621 and the pressure receiving surface 622.

Therefore, when the operating element 50 slides from the second position to the first position along the first direction, the driving inclined surface 511 and the matching inclined surface 621 abut against each other and move relatively, so that the driving end of the transmission lever moves downwards under the action of the driving end 51, the sliding of the operating element 50 is converted into the rotation of the transmission lever, and further converted into the rotation of the first exhaust lever 61a, and further converted into the vertical movement of the exhaust valve 40. And the driving inclined surface 511 is engaged with the engaging inclined surface 621, it is possible to reduce the resistance between the driving end 51 and the actuating lever, making it easier for the operating member 50 to drive the actuating lever to move, and it is easier for the driving end 51 to pass over the restricting protrusion 623 and move to the front side of the restricting protrusion 623 in the first direction. As shown in fig. 14 and 15, when the operating member 50 slides to the first position, the driving end 51 can abut against the pressure receiving surface 622 to prevent the driving end of the driving lever from moving upwards, and the limiting protrusion 623 stops at the rear side of the limiting surface 512 in the first direction to limit the operating member 50. The position-limiting protrusion 623 may be formed as the aforementioned buckling portion 624, at least the lower portion of the driving end 51 may be formed as the aforementioned buckling matching portion 513, and the position-limiting protrusion 623 stops against the position-limiting surface 512, so that the buckling of the buckling portion 624 and the buckling matching portion 513 can be realized.

According to some embodiments of the present invention, as shown in fig. 15, the lower portion of the transmission driving end of the transmission lever may further be provided with a recess 625, the other end of the first exhaust lever 61a may extend into the recess 625, and when the operating element 50 is located at the first position, the upper surface of the recess 625 may press down the other end of the first exhaust lever 61a to move down the other end of the first exhaust lever 61a, and the one end of the first exhaust lever 61a may move up to jack up the exhaust valve 40. The other end of the first exhaust lever 61a extends into the concave part 625, so that the relative position of the first exhaust lever 61a and the transmission lever can be limited, the power transmission is prevented from being influenced by dislocation, the structures of the first exhaust lever 61a and the transmission lever can be more compact, and the occupied space of the locking main body 601 in the vertical direction can be reduced.

According to some embodiments of the present invention, as shown in fig. 25 and 26, the lid assembly 20 may further include a self-locking member 70, the self-locking member 70 is mounted to the lid body 30, and the self-locking member 70 is movable along a radial direction of the lid body 30 to be switchable between a locking state and an unlocking state, when the self-locking member 70 is in the locking state, the self-locking member 70 is locked with the pot body assembly 10 to lock the lid assembly 20 with the pot body assembly 10, the cooking appliance 100 may be pressed to implement pressure cooking, and the self-locking member 70 may prevent the lid assembly 20 from being opened relative to the pot body assembly 10 during the pressure cooking, thereby preventing a dangerous accident from occurring. When the self-locking piece 70 is in the unlocking state, the self-locking piece 70 is unlocked from the pot body assembly 10, and the pot cover assembly 20 can be opened in a rotating mode relative to the pot body assembly 10.

Further, in some embodiments, and with continued reference to fig. 26, the actuator lever may have a reset protrusion 626 that extends to the outside of the self-locking member 70.
