Description

Technical Field

[0001] The present invention relates to the technical field of cooking utensils, and in particular to cooking utensils. Background Art

[0002] High-pressure cooking appliances, such as pressure cookers, typically require first unlocking the latches between the inner lid and outer pot before opening the lid. This requires multiple steps, each with a specific sequence, making it inconvenient and resulting in a poor user experience. While conventional electric pressure cookers offer a one-step lid opening via a twist, the display is typically located on the side of the appliance, making it ergonomically awkward for users to select functions. Summary of the Invention

[0003] In view of this, the present invention provides a cooking utensil to solve the problem that the convenience of opening the lid and the arrangement of the display area in an ergonomic position cannot be achieved at the same time.

[0004] In a first aspect, the present invention provides a cooking appliance comprising:

[0005] The pot body, including the outer pot;

[0006] The lid body comprises an inner lid and a steel lid, wherein one end of the inner lid is hinged to the pot body; the steel lid is rotatably connected to the inner lid, and the steel lid has a locked position for rotationally engaging with the outer pot, and an unlocked position for rotationally unlocking with the outer pot;

[0007] The locking structure includes a limiting end and a force-bearing end. The limiting end cooperates with the steel cover and has a limiting position in which the steel cover is limited to the locked position by cooperating with the steel cover, and a separation position in which the steel cover is separated from the steel cover to release the steel cover. When the force-bearing end is subjected to a cover-opening force, the limiting end is used to drive the limiting end to switch from the limiting position to the separation position.

[0008] The cover opening structure includes a first elastic member connected between the inner cover and the steel cover, and is used to drive the inner cover to rotate from the locked position to the unlocked position.

[0009] Beneficial effect: When the force-bearing end is subjected to the lid-opening force applied by the user, the limiting end of the locking structure is switched from the limiting position to the separation position under the drive of the force-bearing end, and the steel cover is released. Under the action of the lid-opening structure, the steel cover is automatically driven to rotate from the locked position to the unlocked position, thereby realizing the one-step opening of the cooking appliance. Moreover, since the inner cover is hinged to the pot body, the steel cover and the inner cover are rotatably connected, so that during the lid-opening process, it is only necessary to rotate the steel cover, and the one-step opening of the lid can be achieved without rotating the entire cover body, so that the display area can be set on the cover body instead of being arranged on the side of the pot body, so that the user can be ergonomic when selecting functions. Therefore, while achieving the effect of convenient lid opening, the display area can also be arranged in an ergonomic position.

[0010] In an optional embodiment, the cooking utensil further includes a limiting member, one end of which is connected to the steel cover, a through hole is provided on the inner cover, and the other end of the limiting member passes through the through hole and cooperates with the limiting end.

[0011] Beneficial effect: Through the setting of the limiting parts and the through holes, the limiting cooperation between the steel cover and the limiting end can be easily achieved, the structure is simplified, and the limiting end is prevented from interfering with the opening structure when extending between the inner cover and the steel cover, thereby avoiding occupying the space between the inner cover and the steel cover.

[0012] In an optional embodiment, a limiting groove is provided at one end of the limiting member away from the steel cover, and avoidance openings are provided on both groove walls of the limiting groove in the circumferential direction of the steel cover; when the limiting end is in the limiting position, the limiting end is in limiting abutment with the groove wall of the limiting groove; when the limiting end is in the separation position, the limiting end is used to enter or leave the limiting groove through the avoidance opening.

[0013] Beneficial effects: Through the setting of the limit groove, the limit end can be easily matched with the groove wall of the limit groove, thereby limiting and fixing the steel cover to prevent the steel cover from rotating, so that the steel cover remains in the locked position; through the setting of the avoidance mouth, the limit end and the limit member can be easily unlocked and separated, thereby releasing the steel cover, so that the steel cover can automatically rotate to the unlocked position under the drive of the opening structure.

[0014] In an optional embodiment, the through hole is an arc-shaped hole, and the arc-shaped hole is coaxially arranged with the steel cover.

[0015] Beneficial effect: The arc-shaped hole is coaxially arranged with the steel cover, which can avoid motion interference between the limiting member and the inner cover and can also guide and limit the steel cover.

[0016] In an optional embodiment, the cover opening structure includes at least three first elastic members, and the at least three first elastic members are arranged at intervals along the circumference of the steel cover.

[0017] Beneficial effect: At least three first elastic members are arranged at intervals along the circumference of the steel cover, which can make the steel cover more evenly subjected to the opening force of the opening structure and provide a greater opening force to ensure the rotation of the steel cover.

[0018] In an optional embodiment, the cover opening structure further includes:

[0019] a first connecting block, fixedly connected to the steel cover and located between the steel cover and the inner cover;

[0020] The second connecting block is fixedly connected to the inner cover and is located between the steel cover and the inner cover; in the circumferential direction of the steel cover, the second connecting block and the first connecting block are spaced apart; one end of the first elastic member is connected to the first connecting block, and the other end is connected to the second connecting block.

[0021] Beneficial effect: Since there is a gap between the steel cover and the inner cover, the arrangement of the first connecting block and the second connecting block can not only facilitate the connection between the first elastic member and the inner cover and the steel cover, but also ensure that the first elastic member will not be skewed after the connection, thereby ensuring that the cover-opening force applied by the first elastic member is applied in the circumferential direction and will not have a component force in other directions, thereby avoiding the steel cover being skewed or rotated and stuck due to the component force in other directions.

[0022] In an optional embodiment, a first limiting column is protruded from a side of the first connecting block opposite to the second connecting block, and a second limiting column is protruded from a side of the second connecting block opposite to the first connecting block; the first elastic member is a spring, one end of the first elastic member is sleeved on the outer circumference of the first limiting column, and the other end is sleeved on the outer circumference of the second limiting column.

[0023] Beneficial effect: By socketing the first limiting column with one end of the first elastic member, and by socketing the second limiting column with the other end of the first elastic member, the first elastic member can be limited in the circumferential direction of the steel cover by the first connecting block and the second connecting block, and the first elastic member can be limited and fixed in other directions by the first limiting column and the second limiting column, thereby ensuring the stability of the first elastic member.

[0024] In an optional embodiment, the locking structure includes:

[0025] A first lock buckle is rotatably connected to the inner cover, one end of which is the limiting end and the other end is the first lock buckle end;

[0026] A second lock is rotatably connected to the pot body, one end of which is the second lock end and the other end of which is the force-bearing end; the first lock end has an engaged position for engaging with the second lock end and a disengaged position for separating from the second lock end;

[0027] a second elastic member connected between the first lock buckle and the inner cover, and configured to drive the limiting end to move from the limiting position to the separating position when the first lock buckle end is in the releasing position;

[0028] The third elastic member is connected between the second lock buckle and the pot body, and is used to apply a force to the second lock buckle that is opposite to the lid-opening force applied to the force-bearing end.

[0029] Beneficial effect: when the force-bearing end is subjected to the cover-opening force applied by the user, the second lock buckle rotates and drives the second lock buckle end to rotate, so that the first lock buckle end switches from the fastened position to the disengaged position, and the second elastic member applies an elastic force to the first lock buckle, driving the limiting end of the first lock buckle to move from the limiting position to the separation position, and then the steel cover is released. Under the action of the cover-opening structure, the steel cover is automatically driven to rotate from the locked position to the unlocked position, thereby realizing the one-step opening of the cooking appliance; when the force-bearing end is no longer subjected to the cover-opening force applied by the user, the second lock buckle rotates and resets under the drive of the elastic force of the third elastic member. At this time, since the cover body is rotated open as a whole, the first lock buckle and the second lock buckle are separated from each other. Therefore, the first lock buckle is kept in the separation position due to the elastic force of the second elastic member.

[0030] In an optional embodiment, the locking structure further includes a lid opening button movably connected to the pot body; the lid opening button cooperates with the force-bearing end.

[0031] Beneficial effect: the lid opening button is movably connected to the pot body, so that it can be easily inserted into the pot body and cooperate with the force-bearing end. The user can use the lid opening button to apply the lid opening force to the force-bearing end.

[0032] In an optional embodiment, the cooking utensil further comprises a closing cover structure, which is telescopically connected to the cover body and comprises a telescopic end and a driving surface, wherein the telescopic end cooperates with the pot body, and the driving surface slides with the mating surface on the steel cover, and the driving surface or the mating surface is a slope.

[0033] Beneficial effect: During the process of closing the lid, due to the abutment between the telescopic end and the pot body, the lid closing structure and the lid body move relative to each other, and the position of the driving surface changes relative to the steel lid. The driving surface or the mating surface is an inclined surface, which can convert the telescopic movement of the telescopic end relative to the steel lid into a rotational movement of the steel lid, thereby driving the steel lid to rotate from the unlocked position to the locked position.

[0034] In an optional embodiment, the cover-closing structure includes:

[0035] A slider is slidably connected between the inner cover and the surface cover of the cover body; the slider is provided with the driving surface;

[0036] A telescopic rod, one end of which is connected to the slider and faces one end of the pot body, and the other end is the telescopic end. The inner cover is provided with a through hole, and the telescopic end passes through the through hole and cooperates with the pot body;

[0037] A fourth elastic member is connected between the slider and the surface cover.

[0038] Beneficial Effects: During the lid closing process, after the telescopic end contacts the pot body, the position of the slider relative to the inner lid changes as the lid continues to close. The slider approaches the front cover, the telescopic end gradually retracts into the inner lid, and the driving surface gradually separates from the inner lid. The driving surface engages with the mating surface, and the inclined surface converts the separation of the driving surface from the inner lid into rotational movement of the steel lid, thereby driving the steel lid from the unlocked position to the locked position. When the lid is opened, due to the separation of the telescopic end from the pot body, the slider moves away from the front cover under the action of the fourth elastic member, causing the telescopic end to gradually extend out of the inner lid.

[0039] In an optional embodiment, a protrusion is provided on the steel cover, the mating surface is provided on the protrusion, a clearance position is provided on the inner cover, and the protrusion passes through the clearance position to engage with the driving surface.

[0040] Beneficial effect: The arrangement of the avoidance space facilitates the coordination between the steel cover and the closing cover structure.

[0041] In an optional embodiment, the cooking appliance is a pressure cooker. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0060] The following combination Figures 1 to 9 , describing embodiments of the present invention.

[0061] According to an embodiment of the present invention, a cooking utensil is provided, comprising a pot body 1, a lid body 2, a locking structure 3 and a lid opening structure 4; the pot body 1 comprises an outer pot; the lid body 2 comprises an inner cover 21 and a steel cover 22, one end of the inner cover 21 being hinged to the pot body 1; the steel cover 22 being rotatably connected to the inner cover 21, the steel cover 22 having a locking position for rotationally engaging with the outer pot and an unlocking position for rotationally unlocking with the outer pot; the locking structure 3 comprises a limiting end 311 and a force-bearing end 322, the limiting end 311 being hinged to the steel cover 22 The steel cover 22 cooperates with the steel cover 22 to limit the steel cover 22 in the limiting position of the locking position, and separates from the steel cover 22 to release the separation position of the steel cover 22; the force-bearing end 322 is used to drive the limiting end 311 to switch from the limiting position to the separation position when subjected to the cover-opening force; the cover-opening structure 4 includes a first elastic member 41, which is connected between the inner cover 21 and the steel cover 22, and is used to drive the inner cover 21 to rotate from the locking position to the unlocking position.

[0062] When the force-bearing end 322 is subjected to the lid-opening force applied by the user, the limiting end 311 of the locking structure 3 is switched from the limiting position to the separation position under the drive of the force-bearing end 322, and the steel cover 22 is released. Under the action of the lid-opening structure 4, the steel cover 22 is automatically driven to rotate from the locked position to the unlocked position, thereby realizing the one-step opening of the cooking appliance. Moreover, since the inner cover 21 is hinged to the pot body 1, the steel cover 22 is rotatably connected to the inner cover 21, so that during the lid-opening process, it is only necessary to rotate the steel cover 22, and the one-step opening of the lid can be achieved without rotating the entire cover body 2, so that the display area can be set on the cover body 2 instead of being arranged on the side of the pot body 1, so that the user can be ergonomically configured when selecting functions. Therefore, while achieving the effect of convenient lid opening, the display area can also be arranged in an ergonomic position.

[0063] In a specific embodiment, the steel cover 22 is provided with a first claw 223, and the outer pot is provided with a second claw. When the steel cover 22 is in the locked position, the first claw 223 and the second claw are engaged with each other. When the steel cover 22 is in the unlocked position, the first claw 223 and the second claw are staggered with each other. The first claw 223 includes at least three, which are spaced apart along the circumference of the steel cover 22 at the bottom of the steel cover 22. In a preferred embodiment, the at least three first claws 223 are evenly distributed along the circumference of the steel cover 22. The second claws include at least three, which are spaced apart along the circumference of the outer pot at the top of the outer pot. In a preferred embodiment, the at least three second claws are evenly distributed along the circumference of the outer pot. The number and position of the first claws 223 and the second claws are set accordingly.

[0064] In a specific embodiment, a spring-opening structure is further provided between the pot body 1 and the lid body 2. The spring-opening structure applies a force to the lid body 2 to open the lid when the lid body 2 is closed. When the steel lid 22 rotates from the locked position to the unlocked position under the drive of the lid opening structure 4, the spring-opening structure can drive the lid body 2 to rotate and open. In a preferred embodiment, the spring-opening structure is a torsion spring.

[0065] In a further embodiment, one end of the inner cover 21 is hinged to the pot body 1 via a hinge shaft, and the locking structure 3 is provided at the other end opposite to the hinge.

[0066] In one embodiment, the cooking utensil further includes a limiting member 5 , one end of which is connected to the steel cover 22 , a through hole 211 is provided on the inner cover 21 , and the other end of the limiting member 5 passes through the through hole 211 and cooperates with the limiting end 311 to limit the position.

[0067] By setting the limiting member 5 and the through hole 211, it is easy to achieve the limiting cooperation between the steel cover 22 and the limiting end 311, simplifying the structure, and avoiding the limiting end 311 from interfering with the opening structure 4 when extending between the inner cover 21 and the steel cover 22, thereby avoiding occupying the space between the inner cover 21 and the steel cover 22.

[0068] In one embodiment, a limiting groove 51 is provided at one end of the limiting member 5 away from the steel cover 22, and avoidance openings 52 are provided on both groove walls of the limiting groove 51 in the circumferential direction of the steel cover 22; when the limiting end 311 is in the limiting position, the limiting end 311 is in limiting contact with the groove wall of the limiting groove 51; when the limiting end 311 is in the separation position, the limiting end 311 is used to enter or leave the limiting groove 51 through the avoidance opening 52.

[0069] Through the setting of the limiting groove 51, the limiting end 311 can be conveniently matched with the groove wall of the limiting groove 51 to limit and fix the steel cover 22 to prevent the steel cover 22 from rotating, so that the steel cover 22 remains in the locked position; through the setting of the avoidance opening 52, the limiting end 311 can be conveniently unlocked and separated from the limiting member 5, so as to release the steel cover 22, so that the steel cover 22 can automatically rotate to the unlocked position under the drive of the opening structure 4.

[0070] In a specific embodiment, when the force-bearing end 322 is subjected to the cover-opening force applied by the user, the limiting end 311 of the locking structure 3 is switched from the limiting position to the separation position under the drive of the force-bearing end 322, and the limiting end 311 moves from the position of limiting abutment with the groove wall of the limiting groove 51 to the position where the avoidance opening 52 is located, and the limiting effect of the limiting groove 51 on the limiting end 311 disappears. At this time, the steel cover 22 is released, and under the action of the cover-opening structure 4, the steel cover 22 is automatically driven to rotate from the locked position to the unlocked position, and the limiting end 311 leaves the limiting groove 51 through the avoidance opening 52, thereby realizing the one-step opening of the cover of the cooking appliance. When the cover body 2 is closed, the steel cover 22 rotates in the opposite direction against the elastic force of the first elastic member 41 of the cover opening structure 4. The limiting end 311 first enters the limiting groove 51 through the avoidance opening 52, and then switches from the separation position to the limiting position, so that the limiting end 311 is in limiting contact with the groove wall of the limiting groove 51 to lock and limit the steel cover 22.

[0071] In one embodiment, the through hole 211 is an arc-shaped hole, and the arc-shaped hole is coaxially arranged with the steel cover 22 .

[0072] The arc-shaped hole is coaxially arranged with the steel cover 22 , which can avoid motion interference between the limiting member 5 and the inner cover 21 , and can also guide and limit the steel cover 22 .

[0073] In one embodiment, the cover opening structure 4 includes at least three first elastic members 41 , and the at least three first elastic members 41 are arranged at intervals along the circumference of the steel cover 22 .

[0074] At least three first elastic members 41 are arranged at intervals along the circumference of the steel cover 22 , which can make the steel cover 22 receive the opening force of the opening structure 4 more uniformly and provide a greater opening force to ensure the rotation of the steel cover 22 .

[0075] In a preferred embodiment, at least three first elastic members 41 are evenly arranged along the circumference of the steel cover 22 .

[0076] Specifically, in one embodiment, the cover opening structure 4 includes four first elastic members 41 , and the four first elastic members 41 are evenly distributed along the circumference of the steel cover 22 .

[0077] Furthermore, the opening structure 4 may specifically include three first elastic members 41 , four first elastic members 41 , five first elastic members 41 , or more first elastic members 41 , and the number of the first elastic members 41 is not restricted here.

[0078] In one embodiment, the opening cover structure 4 also includes a first connecting block 42 and a second connecting block; the first connecting block 42 is fixedly connected to the steel cover 22 and is located between the steel cover 22 and the inner cover 21; the second connecting block is fixedly connected to the inner cover 21 and is located between the steel cover 22 and the inner cover 21; in the circumferential direction of the steel cover 22, the second connecting block and the first connecting block 42 are spaced apart; one end of the first elastic member 41 is connected to the first connecting block 42, and the other end is connected to the second connecting block.

[0079] Since there is a gap between the steel cover 22 and the inner cover 21, the provision of the first connecting block 42 and the second connecting block can not only facilitate the connection between the first elastic member 41 and the inner cover 21 and the steel cover 22, but also ensure that the first elastic member 41 will not be skewed after the connection, thereby ensuring that the cover-opening force applied by the first elastic member 41 is applied in the circumferential direction and will not have a component force in other directions, thereby avoiding the steel cover 22 being skewed or rotated and stuck due to the component force in other directions.

[0080] In one embodiment, a first limiting column 43 is protruded from the side of the first connecting block 42 opposite to the second connecting block, and a second limiting column is protruded from the side of the second connecting block opposite to the first connecting block 42; the first elastic member 41 is a spring, one end of the first elastic member 41 is sleeved on the outer periphery of the first limiting column 43, and the other end is sleeved on the outer periphery of the second limiting column.

[0081] By socketing the first limiting column 43 with one end of the first elastic member 41, and socketing the second limiting column with the other end of the first elastic member 41, the first elastic member 41 can be limited in the circumferential direction of the steel cover 22 by the first connecting block 42 and the second connecting block, and can also be limited and fixed in other directions by the first limiting column 43 and the second limiting column, thereby ensuring the stability of the first elastic member 41.

[0082] In a further embodiment, the first connecting block 42 and the second connecting block are rectangular blocks, and the first limiting column 43 and the second limiting column are cross-rib-shaped structures with a cross-shaped cross section.

[0083] As a convertible embodiment, the first connecting block 42 may be provided with a first hook, the second connecting block may be provided with a second hook, the first elastic member 41 may be a spring, and both ends of the spring may be detachably connected to the first hook and the second hook respectively.

[0084] In one embodiment, the locking structure 3 includes a first lock buckle 31, a second lock buckle 32, a second elastic member 33 and a third elastic member 34; the first lock buckle 31 is rotatably connected to the inner cover 21, one end of which is the limiting end 311 and the other end is the first lock buckle end 312; the second lock buckle 32 is rotatably connected to the pot body 1, one end of which is the second lock buckle end 321 and the other end is the force-bearing end 322; the first lock buckle end 312 has a buckling position that is mutually buckled with the second lock buckle end 321, and is buckled with the The second lock end 321 is in the disengaged disengaged position; the second elastic member 33 is connected between the first lock 31 and the inner cover 21, and when the first lock end 312 is in the disengaged position, the second elastic member 33 is used to drive the limiting end 311 to move from the limiting position to the separation position; the third elastic member 34 is connected between the second lock 32 and the pot body 1, and the third elastic member 34 is used to apply a force to the second lock 32 that is opposite to the cover-opening force applied to the force-bearing end 322.

[0085] When the lid 22 is unlocked, the second latch 32 is rotated back to its original position by the elastic force of the third elastic member 34. At this time, since the lid 2 is rotated open as a whole, the first latch 31 and the second latch 32 are separated from each other. Therefore, the first latch 31 is kept in the separated position due to the elastic force of the second elastic member 33.

[0086] In a further embodiment, a first connecting hole is provided on either the first locking buckle 31 or the inner cover 21 , and a first rotating shaft is provided on the other one of the first locking buckle 31 and the inner cover 21 , and the first rotating shaft is rotatably connected to the first connecting hole.

[0087] In a specific embodiment, the second elastic member 33 is disposed between the first locking end 312 and the inner cover 21 .

[0088] In a preferred embodiment, a first connecting column is protruded from the first locking end 312, a second connecting column is protruded from the inner cover 21, and the second elastic member 33 is a spring; one end of the second elastic member 33 is sleeved on the outer periphery of the first connecting column, and the other end is sleeved on the outer periphery of the second connecting column.

[0089] In a further embodiment, a second connecting hole is provided on either the second locking buckle 32 or the pot body 1 , and a second rotating shaft is provided on the other of the two, and the second rotating shaft is rotatably connected to the second connecting hole.

[0091] In a preferred embodiment, a third connecting column is protruding from the second lock buckle 32, a fourth connecting column is protruding from the pot body 1, and the third elastic member 34 is a spring; one end of the third elastic member 34 is sleeved on the outer periphery of the third connecting column, and the other end is sleeved on the outer periphery of the fourth connecting column.

[0092] In one embodiment, the locking structure 3 further includes a lid opening button 35 movably connected to the pot body 1 ; the lid opening button 35 cooperates with the force-bearing end 322 .

[0093] The lid opening button 35 is movably connected to the pot body 1 so as to be inserted into the pot body 1 and cooperate with the force-bearing end 322 . The user can apply the lid opening force to the force-bearing end 322 with the help of the lid opening button 35 .

[0094] In one embodiment, the cooking utensil further includes a lid closing structure 6, which is telescopically connected to the lid body 2, and includes a telescopic end 621 and a driving surface 611. The telescopic end 621 cooperates with the pot body 1, and the driving surface 611 slides with the mating surface 222 on the steel cover 22. The driving surface 611 or the mating surface 222 is an inclined surface, which is used to drive the steel cover 22 to rotate from the unlocked position to the locked position.

[0095] During the process of closing the lid, due to the abutment between the telescopic end 621 and the pot body 1, the lid closing structure 6 and the lid body 2 move relative to each other, and the position of the driving surface 611 changes relative to the steel lid 22. The driving surface 611 or the mating surface 222 is a slope, which can convert the telescopic movement of the telescopic end 621 relative to the steel lid 22 into a rotational movement of the steel lid 22, thereby driving the steel lid 22 to rotate from the unlocked position to the locked position.

[0096] In a specific embodiment, the mating surface 222 is an inclined surface.

[0097] In one embodiment, the closing structure 6 includes a slider 61, a telescopic rod 62 and a fourth elastic member; the slider 61 is slidably connected between the inner cover 21 and the surface cover of the cover body 2; the driving surface 611 is provided on the slider 61; one end of the telescopic rod 62 is connected to one end of the slider 61 facing the pot body 1, and the other end is the telescopic end 621, and a through hole is provided on the inner cover 21, and the telescopic end 621 passes through the through hole and cooperates with the pot body 1; the fourth elastic member is connected between the slider 61 and the surface cover.

[0098] During the process of closing the lid, after the telescopic end 621 contacts the pot body 1, when the lid is continued to be closed, the position of the slider 61 relative to the inner lid 21 changes, the slider 61 approaches the direction of the front cover, the telescopic end 621 gradually retracts into the inner lid 21, the driving surface 611 gradually separates from the inner lid 21, the driving surface 611 cooperates with the mating surface 222, and the separation of the driving surface 611 from the inner lid 21 is converted into a rotational movement of the steel cover 22 through the inclined surface, thereby driving the steel cover 22 to move from the unlocked position to the locked position. When opening the lid, due to the separation of the telescopic end 621 from the pot body 1, the slider 61 moves in the direction away from the front cover under the action of the fourth elastic member, causing the telescopic end 621 to gradually extend out of the inner lid 21.

[0099] In a specific embodiment, the fourth elastic member is a spring. The telescopic end 621 cooperates with the support ring of the pot body 1.

[0100] In a further embodiment, the cover-closing structure 6 further includes a limiting component, which is slidably matched with the slider 61 to limit the sliding of the slider 61 .

[0101] In one embodiment, the steel cover 22 is provided with a protrusion 221 , the protrusion 221 is provided with the matching surface 222 , the inner cover 21 is provided with a clearance position 212 , and the protrusion 221 passes through the clearance position 212 to match with the driving surface 611 .

[0102] The arrangement of the avoidance space 212 facilitates the cooperation between the steel cover 22 and the closing cover structure 6 .

[0103] In one embodiment, the cooking appliance is a pressure cooker.

[0104] Specifically, the lid opening process of the cooking appliance in this embodiment includes the following steps: a user presses the lid opening button 35, which applies a lid opening force to the force-bearing end 322. The force-bearing end 322 drives the second latch 32 to rotate, separating the second latch end 321 from the first latch end 312. The first latch end 312 is in the disengaged position. The first latch 31, driven by the second elastic member 33, rotates, causing the limiting end 311 to move from the limiting position to the disengaged position. The limiting end 311 moves from the position of contact with the groove wall of the limiting groove 51 to the position where the escape opening 52 is located. The limiting effect of the limiting groove 51 on the limiting end 311 is no longer exerted, and the steel cover 22 is released. The lid opening mechanism 4 automatically drives the steel cover 22 to rotate from the locked position to the unlocked position. The limiting end 311 leaves the limiting groove 51 through the escape opening 52, thereby achieving one-step lid opening of the cooking appliance. At this point, the second latch 32 is reset under the action of the third elastic member 34, driving the lid opening button 35 to reset.

[0105] Specifically, the closing process of the cooking utensil in this embodiment includes: the user rotates to close the lid 2, the telescopic end 621 extends out of the lid 2 under the action of the fourth elastic member, and abuts against the support ring of the pot body 1 before the lid 2. In the process of continuing to close the lid, the lid 2 gradually approaches the pot body 1, the position of the slider 61 relative to the inner lid 21 changes, the slider 61 approaches the direction of the cover, the telescopic end 621 gradually retracts into the inner lid 21, the driving surface 611 gradually separates from the inner lid 21, the driving surface 611 cooperates with the mating surface 222, and the driving surface 611 is moved by the inclined surface 222. The separation of 11 and the inner cover 21 is converted into the rotational movement of the steel cover 22, thereby driving the steel cover 22 to move from the unlocked position to the locked position. The rotation of the steel cover 22 drives the limit member 5 to rotate. Under the action of the second elastic member 33, the limit end 311 maintained in the separation position enters the limit groove 51 through the avoidance opening 52. At this time, the first locking end 312 and the second locking end 321 are engaged with each other, and the first locking end 312 rotates from the disengaged position to the engaged position, driving the limit end 311 to move from the separation position to the limit position, so as to lock the steel cover 22 in the locked position.

[0106] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by this application.
