Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and more specifically, to a cover assembly and a cooking appliance having the same. Background Art

[0002] At present, due to the characteristics of convenient and fast food processing, cooking appliances are widely used in people's daily lives.

[0003] In the related art, a cooking appliance includes a pot body and a cover assembly covering the pot body, and a pot tooth is provided on the pot body. The cover assembly includes an outer cover and an inner cover. A linkage member is movably provided on the outer cover. The inner cover is detachably and rotatably provided below the outer cover, and a cover tooth cooperating with the pot tooth is provided on the lower edge of the inner cover. When the linkage member moves, it drives the inner cover to rotate below the outer cover.

[0004] In the above related art, due to incorrect operation by the user, the position of the linkage member will be randomly changed, resulting in the inner cover being unable to be installed below the outer cover. It is necessary to separately provide a limiting member to limit the position of the linkage member to prevent incorrect operation by the user. Moreover, during the rotation of the inner cover below the outer cover, in order to prevent the inner cover from tilting, it is necessary to separately provide an anti-deviation member to enable the cover tooth and the pot tooth to be smoothly engaged, that is, the inner cover is in a locked state.

[0005] However, due to separately providing the limiting member and the anti-deviation member, the structure of the cover assembly is complicated, and the manufacturing cost of the cover assembly is also increased. Summary of the Utility Model

[0006] The main object of the present utility model is to provide a cover assembly and a cooking appliance having the same, so as to solve the problem of the complicated structure of the cover assembly in the related art.

[0007] To achieve the above object, according to one aspect of the present utility model, a cover assembly is provided, including: an outer cover, on which a linkage member is movably provided, the linkage member having a first position and a second position, and a sliding groove is provided on the inner side wall of the outer cover; an inner cover, which is detachably and rotatably provided below the outer cover, an insertion block slidably cooperating with the sliding groove is provided on the outer side wall of the inner cover, the width of the sliding groove is greater than the dimension of the insertion block along the width direction of the sliding groove, and a cover tooth cooperating with the pot tooth of the pot body of the cooking appliance is provided on the lower edge of the inner cover; when the linkage member moves, it drives the inner cover to rotate, when the linkage member is in the first position, the inner cover is in an unlocked state, and when the linkage member is in the second position, the inner cover is in a locked state; an elastic abutting member, which is movably inserted through the outer cover and has an initial position for limiting the linkage member in the first position and an avoidance position for avoiding the linkage member so that the linkage member can move; when the inner cover is installed below the outer cover, the inner cover abuts and cooperates with the elastic abutting member, so that the elastic abutting member moves from the initial position to the avoidance position, and the inner cover can float up and down.

[0008] When the technical solution of the present utility model is applied, when the linkage is in the first position during the user's operation of the cooking appliance, the inner lid is in the unlocked state and can be removed from the outer lid. Since the elastic abutting member limits the linkage at the initial position of the first position, it is avoided that the user misoperates the cooking appliance and changes the position of the linkage, effectively preventing the cooking appliance from being misoperated by the user. During the process of installing the inner lid below the outer lid again, the inner lid can be smoothly installed below the outer lid. Moreover, during this process, the inner lid is first tilted relative to the outer lid, and the insertion block is inserted into the sliding groove, and then the inner lid is installed below the outer lid. And, the inner lid will push against the elastic abutting member and abut against the elastic abutting member, so that the elastic abutting member moves from the initial position to the avoidance position. The user can operate the cooking appliance again, and the linkage can be switched between the first position and the second position, so as to facilitate the rotation of the inner lid between the unlocked state and the locked state. During the rotation of the inner lid between the unlocked state and the locked state, since the inner lid abuts against the elastic abutting member, the elastic abutting member can apply a pressure to the inner lid, which can overcome the possible inclination of the inner lid, facilitate the rotation of the inner lid in the horizontal direction, and thus avoid the possible interference between the lid teeth and the pot teeth, making the opening and closing of the lid assembly smooth. Moreover, when the inner lid is in the locked state, during the cooking process of the cooking appliance, since the width of the sliding groove is greater than the dimension of the insertion block along the width direction of the sliding groove, as the pressure inside the cooking appliance increases, the inner lid can overcome the pressure applied by the elastic abutting member to the inner lid and float smoothly upward, and the insertion block slides upward in the sliding groove along the floating direction of the inner lid. Therefore, in the present application, only the elastic abutting member needs to be designed to be able to play a limiting role and an anti-deviation role, and moreover, as the pressure on the cooking appliance increases, the inner lid can float smoothly upward. One component can achieve multiple functions, making the structure of the lid assembly simple and also reducing the manufacturing cost of the lid assembly. Therefore, the technical solution of the present application effectively solves the problem of the complex structure of the lid assembly in the related art.

[0009] Further, when the linkage is movably arranged, when the elastic abutting member is in the initial position, it blocks the movement of the linkage, and when the elastic abutting member is in the avoidance position, it avoids the movement of the linkage; or, when the linkage is swingably arranged, when the elastic abutting member is in the initial position, it blocks the swing of the linkage, and when the elastic abutting member is in the avoidance position, it avoids the swing of the linkage. Whether the above-mentioned linkage is movably arranged or swingably arranged, when the elastic abutting member is in the initial position, the linkage cannot move, and when the elastic abutting member is in the avoidance position, it is also convenient for the linkage to be switched between the first position and the second position.

[0010] Further, a guiding hole for guiding the elastic abutting member is provided on the outer cover. The elastic abutting member includes a rod portion passing through the guiding hole and a block portion connected to the rod portion. The inner cover can be in abutting cooperation with the rod portion. When the inner cover is separated from the rod portion and the block portion is in limiting cooperation with the linkage member, the elastic abutting member is in the initial position; when the inner cover is in abutting cooperation with the rod portion and the block portion is in avoidance cooperation with the linkage member, the elastic abutting member is in the avoidance position. In the above structure, the elastic abutting member passes through the guiding hole, which facilitates the installation of the elastic abutting member and guides the movement of the elastic abutting member relative to the inner lining, enabling the elastic abutting member to move smoothly and reliably between the initial position and the avoidance position.

[0011] Further, the elastic abutting member further includes an elastic member disposed between the outer cover and the elastic abutting member. The elastic member applies an elastic force to the elastic abutting member to keep the elastic abutting member in the initial position. In the above structure, when the inner cover is missing, the elastic abutting member restricts the movement of the linkage member, and the inner cover cannot be switched from the locked state to the unlocked state, avoiding the operation of closing the cover with the inner cover missing.

[0012] Further, the rod portion includes a first rod segment and a second rod segment connected to the first rod segment. The diameter of the second rod segment is smaller than that of the first rod segment. The first rod segment is in guiding cooperation with the guiding hole. The inner cover can be in abutting cooperation with the first rod segment. A stop surface is formed between the second rod segment and the first rod segment. The elastic member is located between the outer cover and the stop surface. In the above structure, during the rotation of the inner cover relative to the outer cover, when the first rod segment is in guiding cooperation with the guiding hole, the first rod segment applies a pressure perpendicular to the guiding direction of the guiding hole to the inner cover, enabling the inner cover to rotate smoothly and effectively reducing the possibility of the inner cover tilting.

[0013] Further, the cover assembly further includes a mounting seat for mounting the elastic abutting member. The mounting seat is provided with a mounting hole for the elastic abutting member to pass through. The elastic member is disposed between the mounting seat and the rod portion. In the above structure, by disposing the elastic member between the mounting seat and the rod portion, it is convenient to install the elastic member, and during the floating process of the inner cover, the elastic member can be prevented from falling off.

[0014] Further, in order for the linkage member to be stably and reliably limited to the first position by the elastic abutting member, a blocking surface capable of being in limiting cooperation with the elastic abutting member is provided on the linkage member.

[0015] Further, there are multiple elastic abutting members, and the multiple elastic abutting members are arranged at intervals around the axis of the outer cover. In the above structure, during the rotation of the inner cover relative to the outer cover, the elastic expansion and contraction of the multiple elastic abutting members can be utilized to overcome the possibility of the inner cover tilting, thereby avoiding interference between the cover teeth and the pot teeth and enabling the cover assembly to open and close smoothly.

[0016] Further, when the inner lid is installed below the outer lid, a butt-joint plane for butt-joint cooperation with the elastic abutting member is provided on the upper surface of the inner lid. In the above structure, since the elastic abutting member is in butt-joint cooperation with the butt-joint plane on the upper surface of the inner lid, during the process of covering the pot body with the lid assembly and the inner lid rotating relative to the outer lid, the elastic abutting member can be used to support the inner lid, effectively preventing the inner lid from tilting.

[0017] Further, a stopper is provided on the inner side wall of the outer lid, and a support surface and an avoidance concave surface are provided on the outer side wall of the inner lid. When the inner lid is installed on the outer lid and the lid teeth and the pot teeth are separated, the support surface is in stop cooperation with the stopper. When the inner lid rotates below the outer lid to engage the lid teeth and the pot teeth together, the avoidance concave surface is in avoidance cooperation with the stopper. In the above structure, when installing the inner lid, the inner lid needs to be tilted relative to the outer lid. When the inner lid is installed on the outer lid, first use the support surface to be in stop cooperation with the stopper to make the inner lid in a horizontal state, and then the inner lid rotates relative to the outer lid. When the lid teeth and the pot teeth are engaged together, use the avoidance concave surface to avoid the stopper, so that when the inner lid floats, the stopper can float in the avoidance concave surface.

[0018] Further, a guide groove is also provided on the inner side wall of the outer lid, and a clamping block for guiding cooperation with the guide groove is provided on the outer side wall of the inner lid; the lid assembly further includes a supporting member movably provided on the outer lid. The supporting member has an avoidance position for avoiding the insertion block from entering the sliding groove and a supporting position for supporting the insertion block to keep the insertion block in the sliding groove. When the supporting member is in the avoidance position, the inner lid can be removed from the outer lid. When the supporting member is in the supporting position, the inner lid is installed on the outer lid. In the above structure, when installing the inner lid, the inner lid is tilted relative to the outer lid to insert the insertion block into the sliding groove, and then the inner lid is pushed, so that with the insertion block as the swing point, the inner lid swings towards the direction close to the outer lid, and the clamping block extends into the guide groove, thereby installing the inner lid on the outer lid. When disassembling the inner lid, pull the inner lid, so that with the insertion block as the swing point, the inner lid swings away from the outer lid, and the clamping block disengages from the guide groove. The inner lid is tilted relative to the outer lid to facilitate taking out the insertion block from the sliding groove.

[0019] According to another aspect of the present invention, a cooking appliance is provided, including a lid assembly, and the lid assembly is the above-mentioned lid assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] As Figures 1 to 15a shown, the present application provides a cover assembly. Embodiment 1 of the cover assembly includes: an outer cover 10, an inner cover 20, a handle 30, and an elastic abutting member 40. A linkage member 31 is movably provided on the outer cover 10. The linkage member 31 has a first position and a second position. A sliding groove 11 is provided on the inner side wall of the outer cover 10. The handle 30 is movably provided on the outer cover 10 and can drive the linkage member 31 to move. The inner cover 20 is detachably and rotatably provided below the outer cover 10. An insertion block 21 slidably engaged with the sliding groove 11 is provided on the outer side wall of the inner cover 20. The width of the sliding groove 11 is greater than the dimension of the insertion block 21 along the width direction of the sliding groove 11. A cover tooth 22 adapted to be engaged with the pot teeth of the pot body of the cooking appliance is provided at the lower edge of the inner cover 20. When the linkage member 31 moves, it drives the inner cover 20 to rotate. When the linkage member 31 is in the first position, the inner cover 20 is in an unlocked state. When the linkage member 31 is in the second position, the inner cover 20 is in a locked state. The elastic abutting member 40 is movably inserted through the outer cover 10 and has an initial position for limiting the linkage member 31 to the first position and an avoidance position for avoiding the linkage member 31 so that the linkage member 31 can move. When the inner cover 20 is installed below the outer cover 10, the inner cover 20 abuts and cooperates with the elastic abutting member 40, so that the elastic abutting member 40 moves from the initial position to the avoidance position, and the inner cover 20 can float up and down.

[0060] Applying the technical solution of Application Example 1, when the user operates the handle 30 to move and drives the linkage member 31 to be in the first position, the inner cover 20 is in the unlocked state, and the inner cover 20 can be detached from the outer cover 10. Since the elastic abutting member 40 limits the linkage member 31 to the initial position of the first position, it avoids the user from accidentally operating the handle 30 and changing the position of the linkage member 31, effectively preventing the handle from being accidentally operated by the user. During the process of installing the inner cover 20 below the outer cover 10 again, the inner cover 20 can be smoothly installed below the outer cover 10. Moreover, during this process, the inner cover 20 is first tilted relative to the outer cover 10, and the insertion block 21 is inserted into the sliding groove 11, and then the inner cover 20 is installed below the outer cover 10. And, the inner cover 20 will push against the elastic abutting member 40 and abut against the elastic abutting member 40 in a mating manner, so that the elastic abutting member 40 moves from the initial position to the avoidance position. The user can operate the handle 30 to move again, so that the linkage member 31 switches between the first position and the second position, so as to facilitate the rotation of the inner cover 20 between the unlocked state and the locked state. During the rotation of the inner cover 20 between the unlocked state and the locked state, since the inner cover 20 abuts against the elastic abutting member 40 in a mating manner, the elastic abutting member 40 can apply a pressure to the inner cover 20, which can overcome the possible inclination of the inner cover 20, facilitating the rotation of the inner cover 20 in the horizontal direction, thereby avoiding the possible interference between the cover teeth and the pot teeth, and making the opening and closing of the cover assembly smooth. Moreover, when the inner cover 20 is in the locked state, during the cooking process of the cooking appliance, since the width of the sliding groove 11 is greater than the dimension of the insertion block 21 along the width direction of the sliding groove 11, as the pressure inside the cooking appliance increases (i.e., upward pressure), the inner cover 20 can overcome the pressure applied by the elastic abutting member 40 to the inner cover 20 and float smoothly upward, and the insertion block slides upward in the sliding groove along the floating direction of the inner cover 20. Therefore, in Embodiment 1, only the elastic abutting member 40 needs to be designed to be able to play a limiting role and an anti-deviation role, and moreover, as the cooking appliance is pressed upward, the inner cover 20 can float smoothly. One component can achieve multiple functions, which not only makes the structure of the cover assembly simple, but also reduces the manufacturing cost of the cover assembly. Therefore, the technical solution of Embodiment 1 effectively solves the problem of the complex structure of the cover assembly in the related art.

[0061] It should be noted that in this embodiment, the linkage member 31 is driven to move by the handle 30. In other embodiments, the linkage member 31 is driven to move by a driving motor, and a trigger switch is provided on the cooking appliance for turning on or off the driving motor. Since the elastic abutting member 40 limits the linkage member 31 to the initial position of the first position, it avoids the user from accidentally operating the trigger switch and changing the position of the linkage member 31, effectively preventing the trigger switch from being accidentally operated by the user.

[0062] Among them, when installing the inner cover 20, the inner cover 20 is inclined relative to the outer cover 10 to insert the insertion block 21 into the sliding groove 11, and then the inner cover 20 is pushed. Thus, with the insertion block 21 as the swing point, the inner cover 20 swings towards the direction close to the outer cover 10, so as to install the inner cover 20 on the outer cover 10. When disassembling the inner cover 20, the inner cover 20 is pulled. Thus, with the insertion block 21 as the swing point, the inner cover 20 swings towards the direction away from the outer cover 10, and the inner cover 20 is inclined relative to the outer cover 10 to facilitate taking out the insertion block 21 from the sliding groove 11.

[0063] A linkage hole is provided on the linkage member 31, a driving column 25 penetrating through the linkage hole is provided on the inner cover 20, and an arc-shaped guiding hole for the driving column 25 to pass through is provided on the outer cover 10. The handle 30 can drive the linkage member 31 to move. When the linkage member 31 moves, it can drive the inner cover 20 to rotate through the driving column 25. The linkage hole is a strip-shaped hole. During the process that the linkage member 31 drives the driving column 25 to rotate through the linkage hole, the driving column 25 moves in the arc-shaped guiding hole along the extending direction of the arc-shaped guiding hole, and the driving column 25 also moves in the strip-shaped hole along the extending direction of the strip-shaped hole. Thus, during the movement of the linkage member 31, it is convenient to maintain the driving cooperation between the linkage hole and the driving column 25.

[0064] In the related art, a pivot shaft is provided at the central position of the outer cover, and the inner cover is connected to the pivot shaft by means of a nut, so that the pivot shaft and the inner cover are movably connected.

[0065] Such as Figures 4 to 7 、 Figure 10 and Figure 12 As shown, in the first embodiment, an exhaust pipe 70 penetrates through the outer cover 10, and a first avoidance hole for the exhaust pipe 70 to pass through is provided on the inner cover 20. In this way, the first avoidance hole only avoids the exhaust pipe 70. Since the pivot shaft in the related art is not provided on the outer cover 10, the first avoidance hole does not need to be set as a pivot hole for cooperating with the pivot shaft, reducing components and lowering costs. Moreover, the exhaust pipe 70 provided on the outer cover 10 will not interfere with the pivot shaft in the related art, and there is no need to adjust the original set position of the exhaust pipe 70 on the outer cover 10, ensuring the original layout design on the outer cover 10. That is, on the premise that only minimal modifications are made to the cover assembly of the present application, the exhaust pipe 70 can be retained at the original position. In this way, during the mold processing of the outer cover 10 and the inner cover 20, there is no need to make major adjustments to the mold, which can reduce the design cost and improve the processing efficiency. The axis of the exhaust pipe 70 is arranged to coincide with the rotation axis of the inner cover 20.

[0066] In the first embodiment, a pressure limiting valve that can be opened and closed is provided on the exhaust pipe 70.

[0067] Such as Figure 5 and Figure 6As shown, when the linkage member 31 is moved, the elastic push member 40 blocks the linkage member 31 when it is in the initial position, and the linkage member 31 cannot move. When the elastic push member 40 is in the avoidance position, it avoids the movement of the linkage member 31, so that the linkage member 31 can switch between the first position and the second position.

[0068] like Figures 5 to 8 As shown, in the first embodiment, the handle 30 is a push-pull rod, the outer cover 10 includes an inner lining 17 disposed on the outer side of the inner cover 20 and a surface cover 18 disposed on the outer side of the inner lining 17, the linkage member 31 is movably disposed on the inner lining 17, the push-pull rod includes a first gripping portion and a driving portion connected to the first gripping portion, the first gripping portion is rotatably disposed on the surface cover 18, a second avoidance hole for avoiding the driving portion is disposed on the surface cover 18, and the driving portion can drive the linkage member 31 to move. By utilizing the structure that the surface cover 18 can cover the inner lining 17 and the outer surface of the inner lining 17, the user operates the first gripping portion disposed on the surface cover 18 to drive the linkage member 31 disposed on the inner lining 17 to switch between the first position and the second position through the driving portion penetrating the second avoidance hole.

[0069] like Figures 5 to 8 As shown, in the first embodiment, the linkage member 31 is a slide plate 311. The user operates the first gripping portion provided on the cover 18 to drive the slide plate 311 to move in the horizontal direction through the driving portion provided in the second avoidance hole, so that the linkage member 31 switches between the first position and the second position. When the elastic abutting member 40 is in the initial position, the elastic abutting member 40 can be limitedly matched with the slide plate 311 in the moving direction of the slide plate 311.

[0070] like Figures 5 to 8 As shown, a limiting groove 14 for the slide plate 311 to move in the horizontal direction is provided on the outer wall of the lining 17, and the limiting groove 14 has a first limiting groove wall 141 and a second limiting groove wall 142 which are relatively arranged along the moving direction of the slide plate 311. When the slide plate 311 is limitedly matched with the first limiting groove wall 141, the linkage member 31 is in the first position, and when the slide plate 311 is limitedly matched with the second limiting groove wall 142, the linkage member 31 is in the second position.

[0071] like Figures 5 to 8 As shown, a handle seat is provided on the face cover 18, a first gripping portion is rotatably provided on the handle seat, a slide plate 311 comprises a plate body 3111 and a support seat 3112 provided on the plate body 3111, a U-shaped driving groove 3113 extending in the up-down direction of the outer cover 10 is provided on the support seat 3112, a driving portion comprises a driving shaft passing through the U-shaped driving groove 3113. By flipping the first gripping portion, the driving portion is driven to swing relative to the handle seat, the driving shaft moves in the U-shaped driving groove 3113 along the up-down direction of the outer cover 10, and drives the slide plate 311 to move horizontally relative to the lining 17.

[0072] As Figure 11 and Figure 13 shown, a guiding hole 12 for guiding the elastic abutting member 40 is provided on the outer cover 10. The elastic abutting member 40 includes a rod portion 41 inserted into the guiding hole 12 and a block portion 42 connected to the rod portion 41. The inner cover 20 can be in abutting cooperation with the rod portion 41. When the inner cover 20 is separated from the rod portion 41 and the block portion 42 is in limiting cooperation with the linkage member 31, the elastic abutting member 40 is in the initial position; when the inner cover 20 is in abutting cooperation with the rod portion 41 and the block portion 42 is in avoidance cooperation with the linkage member 31, the elastic abutting member 40 is in the avoidance position. With the elastic abutting member 40 having the above structure, the elastic abutting member 40 is inserted into the guiding hole 12, which facilitates the installation of the elastic abutting member 40 and guides the movement of the elastic abutting member 40 relative to the inner lining 17, enabling the elastic abutting member 40 to move smoothly and reliably between the initial position and the avoidance position.

[0073] As Figures 10 to 13 shown, when the elastic abutting member 40 is in the initial position, the lower end of the rod portion 41 and the lower surface of the inner lining have a first distance, the lower surface of the block portion 42 is lower than the upper surface of the plate body 3111, and the lower surface of the block portion 42 and the upper surface of the plate body 3111 have a second distance. When the elastic abutting member 40 is in the avoidance position, the lower end of the rod portion 41 and the lower surface of the inner lining have a third distance. Among them, the first distance minus the third distance is greater than the second distance.

[0074] As Figure 11 and Figure 13 shown, the elastic abutting member 40 further includes an elastic member 43 provided between the outer cover 10 and the elastic abutting member 40. The elastic member 43 applies an elastic force to the elastic abutting member 40 to keep the elastic abutting member 40 in the initial position. When the inner cover 20 is disassembled, the inner cover 20 is separated from the elastic abutting member 40. The elastic abutting member 40 is acted on by the elastic force of the elastic member 43, so that the linkage member 31 moves from the avoidance position to the initial position and remains in the initial position. Thus, when the inner cover 20 is missing, the elastic abutting member 40 restricts the movement of the linkage member 31, making the handle 30 inoperable and the cover assembly unable to be closed (i.e., switched from the locked state to the unlocked state), avoiding the operation of closing the cover when the inner cover 20 is missing.

[0075] As Figure 9 , Figure 11 and Figure 13As shown, the rod portion 41 includes a first rod segment 411 and a second rod segment 412 connected to the first rod segment 411. The diameter of the second rod segment 412 is smaller than that of the first rod segment 411. The first rod segment 411 is in guiding cooperation with the guiding hole 12. The inner cover 20 can be in abutting cooperation with the first rod segment 411. A stop surface 413 is formed between the second rod segment 412 and the first rod segment 411. The elastic member 43 is located between the outer cover 10 and the stop surface 413. During the rotation of the inner cover 20 relative to the outer cover 10, when the first rod segment 411 is in guiding cooperation with the guiding hole 12, the first rod segment 411 applies a pressure perpendicular to the guiding direction of the guiding hole 12 to the inner cover 20, so as to enable the inner cover 20 to achieve balanced rotation and effectively reduce the possibility of the inner cover 20 tilting. The elastic member 43 is preferably a spring. By sleeving the spring on the second rod segment 412 and arranging the spring between the face cover 18 and the stop surface 413, it is convenient to install the spring and at the same time it is also convenient for the spring to apply an elastic force towards the inner cover 20 to the rod portion 41.

[0076] As Figure 5 , Figure 6 , Figure 11 and Figure 13 shown, in order to facilitate the installation of the elastic abutting member 40 on the outer cover 10, the cover assembly further includes a mounting seat 51 for mounting the elastic abutting member 40. An installation hole 511 for the elastic abutting member 40 to pass through is provided on the mounting seat 51. The elastic member 43 is arranged between the mounting seat 51 and the rod portion 41. By arranging the elastic member 43 between the mounting seat 51 and the rod portion 41, it is convenient to install the elastic member 43, and during the floating of the inner cover 20, the elastic member 43 can be prevented from falling off.

[0077] As Figure 5 , Figure 6 , Figure 11 and Figure 13 shown, in order to enable the linkage member 31 to be stably and reliably limited to the first position by the elastic abutting member 40, a blocking surface 32 capable of being in limiting cooperation with the elastic abutting member 40 is provided on the linkage member 31.

[0078] As Figures 4 to 6 , Figure 10 and Figure 12As shown, there are multiple elastic abutting members 40, and the multiple elastic abutting members 40 are arranged at intervals around the axis of the outer cover 10. The multiple elastic abutting members 40 are all in contact with the outer top wall of the inner cover 20, so that the inner cover 20 can float relative to the pot body in a direction close to or away from the outer cover 10. Thus, when the cover assembly is placed on the pot body and the inner cover 20 rotates relative to the outer cover 10, the elastic expansion and contraction of the multiple elastic abutting members 40 can be utilized to overcome the possibility of the inner cover 20 tilting, thereby avoiding interference between the cover teeth and the pot teeth and making the opening and closing of the cover assembly smooth. During the cooking process, with the change of pressure inside the cooking appliance, the elastic expansion and contraction of the multiple elastic abutting members 40 are utilized to make the inner cover 20 float relative to the pot body in a direction close to or away from the outer cover 10.

[0079] "Multiple" in this application means at least two in number. Of course, the number of the elastic abutting members 40 can be one.

[0080] It should be noted that when an elastic abutting member 40 is arranged on the outer cover and on the side close to the insertion block 21, the insertion block of the inner cover can rotate along the chute, avoiding the tilting of the inner cover 20.

[0081] When an elastic abutting member 40 is arranged at a position far from both the insertion block and the clamping block at the same time, the three components formed by the elastic abutting member 40, the insertion block and the clamping block (see below) enable the inner cover to rotate on a plane, and can also avoid the tilting of the inner cover 20.

[0082] When the inner cover 20 is circular, an elastic abutting member 40 is arranged on the outer cover. In the circumferential direction of the inner cover 20, the elastic abutting member 40 is arranged at intervals from the chute 11. When the inner cover 20 rotates relative to the outer cover 10 and the insertion block 21 slides in the chute 11 along the rotation direction, due to the interval arrangement of the elastic abutting member 40 and the chute 11, the pressure exerted by the elastic abutting member 40 on the inner cover 20 enables the insertion block 21 to maintain the state of sliding in the chute 11 along the rotation direction, so as to facilitate the smooth rotation of the inner cover 20.

[0083] As Figure 3 、 Figure 4 、 Figure 12 and Figure 13 As shown, when the inner cover 20 is installed below the outer cover 10, the upper surface of the inner cover 20 is provided with a butting plane 23 that abuts and cooperates with the elastic abutting member 40. Since the elastic abutting member 40 abuts and cooperates with the butting plane 23 on the upper surface of the inner cover 20, during the process of covering the cover assembly on the pot body and the inner cover 20 rotating relative to the outer cover 10, the elastic abutting member 40 can be utilized to support the inner cover 20, effectively preventing the inner cover 20 from tilting.

[0084] Moreover, the upper surface of the inner cover 20 with the above structure has the advantages of simple structure and easy processing.

[0085] AsFigure 1 , Figure 3 and Figure 4 As shown in Figure 1 , Figure 3 , and Figure 4 , a stopper 52 is provided on the inner side wall of the outer lid 10, and a support surface 53 and an avoidance concave surface 54 are provided on the outer side wall of the inner lid 20. When the inner lid 20 is installed on the outer lid 10 and the lid teeth 22 and the pot teeth are separated, the support surface 53 and the stopper 52 are in a stop fit. When the inner lid 20 rotates below the outer lid 10 to engage the lid teeth 22 and the pot teeth together, the avoidance concave surface 54 and the stopper 52 are in an avoidance fit. When installing the inner lid 20, the inner lid 20 needs to be inclined relative to the outer lid 10. When the inner lid 20 is installed on the outer lid 10, first, the support surface 53 and the stopper 52 are in a stop fit, so that the inner lid 20 is in a horizontal state. Then, the inner lid 20 rotates relative to the outer lid 10. When the lid teeth 22 and the pot teeth are engaged together, the avoidance concave surface 54 avoids the stopper 52, so that when the inner lid 20 floats, the stopper 52 can float in the avoidance concave surface 54.

[0086] As Figures 1 to 4 , Figure 14 and Figure 15a As shown in Figures 1 to 4 , Figure 14 , and Figure 15a , a guide groove 13 is further provided on the inner side wall of the outer lid 10, and a clamping block 24 that is in guiding cooperation with the guide groove 13 is provided on the outer side wall of the inner lid 20. When installing the inner lid 20, the inner lid 20 is inclined relative to the outer lid 10 to insert the insertion block 21 into the sliding groove 11, and then the inner lid 20 is pushed, so that with the insertion block 21 as the swing point, the inner lid 20 swings towards the outer lid 10, so that the clamping block 24 extends into the guide groove 13, thereby installing the inner lid 20 on the outer lid 10. When disassembling the inner lid 20, the inner lid 20 is pulled, so that with the insertion block 21 as the swing point, the inner lid 20 swings away from the outer lid 10, so that the clamping block 24 disengages from the guide groove 13, and the inner lid 20 is inclined relative to the outer lid 10 to facilitate taking out the insertion block 21 from the sliding groove 11.

[0087] Moreover, in the first embodiment, the dimension of the guide groove 13 along the circumferential direction of the outer lid 10 is larger than the dimension of the clamping block 24 along the circumferential direction of the outer lid 10. When the inner lid 20 rotates relative to the outer lid 10, the clamping block 24 slides in the guide groove 13 along the rotation direction. The width of the guide groove 13 is larger than the dimension of the clamping block 24 along the width direction of the guide groove 13. During the floating process of the inner lid 20, the clamping block 24 slides in the guide groove 13 along the floating direction.

[0088] As Figure 1 , Figure 4 , Figure 14 and Figure 15aAs shown, the cover assembly further includes a support member 63 movably disposed on the outer cover 10. The support member 63 has an avoidance position for avoiding the insertion block 21 from entering the chute 11 and a support position for supporting the insertion block 21 to keep the insertion block 21 in the chute 11. When the support member 63 is in the avoidance position, the inner cover 20 can be detached from the outer cover 10. When the support member 63 is in the support position, the inner cover 20 is installed on the outer cover 10. When installing the inner cover 20, the inner cover 20 inclined relative to the outer cover 10 inserts the insertion block 21 into the chute 11, and then pushes the inner cover 20. Thus, with the insertion block 21 as the swing point, the inner cover 20 swings towards the direction close to the outer cover 10, so that the latch 24 presses the support member 63, the support member 63 switches to the avoidance position, the latch 24 extends into the guide groove 13, and the support member 63 switches to the support position, thereby installing the inner cover 20 on the outer cover 10. When detaching the inner cover 20, the support member 63 is switched to the avoidance position, and the inner cover 20 is pulled. Thus, with the insertion block 21 as the swing point, the inner cover 20 swings towards the direction away from the outer cover 10, so that the latch 24 disengages from the guide groove 13, and the inner cover 20 is inclined relative to the outer cover 10 to facilitate taking out the insertion block 21 from the chute 11.

[0089] As Figure 1 , Figure 4 , Figure 14 and Figure 15a shown, in the first embodiment of the support member of the cover assembly, the outer cover 10 is provided with a notch 16 communicating with the guide groove 13. The support member 63 is disposed in the notch 16, and the latch 24 can enter and exit the guide groove 13 through the notch 16. The outer cover 10 is provided with a button 64 for driving the support member 63 to switch between the support position and the avoidance position. The support member 63 includes a support hook 631 movably disposed in the transverse direction within the outer cover 10. The support hook 631 is applied with an elastic force by a first return spring to keep the support member 63 in the support position.

[0090] In embodiment one, the button 64 can drive the supporting hook 631 to move laterally in the outer cover 10. When the supporting member 63 is in the supporting position, the inner cover 20 is placed on the supporting hook 631. The cover body assembly also includes a first return spring, which is arranged between the supporting hook 631 and the outer cover 10 and applies an elastic force to the supporting hook 631 toward the inner cover 20. The supporting member 63 with the above structure can drive the supporting hook 631 to move horizontally in the outer cover 10 by controlling the button 64. The first return spring is arranged between the supporting hook 631 and the outer cover 10. When the supporting member 63 is in the supporting position, the inner cover 20 is placed on the supporting hook 631. Under the action of the first return spring, the supporting hook 631 can be exerted with elastic force, thereby ensuring that the inner cover 20 is placed on the supporting hook 631. When it is necessary to control the supporting member 63 to switch from the supporting position to the avoidance position, the button 64 is pressed, so that the button 64 moves to drive the supporting hook 631 to overcome the elastic force of the first return spring to move, thereby ensuring that the inner cover 20 is detached from the supporting hook 631 for disassembly.

[0091] Compared with the detachable inner cover for repairing the cover assembly in the conventional setting, the support member 63 of this embodiment is controlled by the button 64 to move to the supporting position relative to the outer cover 10, and the inner cover 20 can be placed on the support member 63 to ensure that the inner cover 20 is installed on the outer cover 10. The support member 63 and the inner cover 20 are overlapped and matched, so that the inner cover 20 can be prevented from being separated from the outer cover 10, making the installation method convenient. When the inner cover 20 is removed from the outer cover 10, the support member 63 is controlled by the button 64 to move from the supporting position to the avoidance position, so that the inner cover 20 is easily removed from the outer cover 10, and one-button quick removal and easy removal are achieved, so that the user can clean the removed inner cover 20 and outer cover 10. With the cover body assembly adopting the above-mentioned structure, the supporting member 63 on the outer cover 10 can not only facilitate the disassembly and assembly of the inner cover 20 and the outer cover 10, but also when the inner cover 20 is placed on the supporting member 63, the supporting member 63 can support the inner cover 20, and the inner cover 20 can rotate relative to the supporting member 63, which guides the rotation of the inner cover 20, thereby improving the structural reliability and practicality of the cover body assembly.

[0092] like Figure 1 , Figure 4 , Figure 14 and Figure 15bAs shown, in the second embodiment of the supporting member of the cover assembly, the supporting member 63 includes a pull button 632 swingably disposed on the outer cover 10, and the cover assembly further includes a second return spring, and the pull button 632 is swingably disposed on the outer cover 10. When the supporting member 63 is in the supporting position, the inner cover 20 is placed on the pull button 632, and the second return spring is disposed between the pull button 632 and the outer cover 10, and applies an elastic force toward the inner cover 20 to the pull button 632. The supporting member 63 adopts the above-mentioned structure and is swingably set on the outer cover 10 by means of a pull button 632. The second reset spring is set between the pull button 632 and the outer cover 10. Therefore, when the supporting member 63 is in the supporting position, under the action of the second reset spring, the inner cover 20 is ensured to be placed on the pull button 632. When the inner cover 20 is disassembled, the pull button 632 is controlled to swing in the direction away from the inner cover 20, so that the pull button 632 overcomes the elastic force of the second reset spring, thereby ensuring that the inner cover 20 is separated from the pull button 632. Thereafter, the pull button 632 is reset under the elastic force of the second reset spring. The operation method is simple, and one-click quick disassembly and easy disassembly are achieved.

[0093] like Figures 16 to 26 As shown, in the second embodiment of the cover assembly, the difference from the first embodiment of the cover assembly is that the structures of the handle 30 and the linkage member 31 are different. In the second embodiment, the handle 30 is a knob, and the linkage member 31 is a swing rod 312 that can swing in a horizontal plane. When the linkage member 31 is set to swing, when the elastic push member 40 is in the initial position, it blocks the linkage member 31, and the linkage member 31 cannot swing. When the elastic push member 40 is in the avoidance position, it avoids the swing of the linkage member 31, and the linkage member 31 can swing between the first working position and the second working position.

[0094] In the second embodiment, the outer cover 10 is provided with an exhaust pipe 70, and the inner cover 20 is provided with a third avoidance hole for the exhaust pipe 70 to pass through, and the third avoidance hole is preferably a circular hole. The axis of the exhaust pipe 70 is parallel to the rotation axis of the inner cover 20 and there is a preset distance between them.

[0095] like Figures 20 to 25 As shown, the outer cover 10 includes an inner lining 17 disposed on the outer side of the inner cover 20 and a face cover 18 disposed on the outer side of the inner lining 17, a linkage member 31 is movably disposed on the inner lining 17, the handle 30 includes a second gripping portion, the second gripping portion is connected to the linkage member 31, a fourth avoidance hole for avoiding the second gripping portion is disposed on the face cover 18, and the second gripping portion can drive the linkage member 31 to move. By utilizing the structure that the face cover 18 can shield the inner lining 17 and the outer surface of the inner lining 17, the user can operate the part of the second gripping portion located outside the face cover 18, and drive the linkage member 31 disposed on the inner lining 17 to switch between the first position and the second position through the part of the second gripping portion located inside the face cover 18.

[0096] The user operates the part of the second holding part located outside the face cover 18, and drives the swing rod 312 to swing through the part of the second holding part located inside the face cover 18. When the elastic abutting member 40 is in the initial position, the elastic abutting member 40 can be in limit cooperation with the swing rod 312 in the swinging direction of the swing rod 312.

[0097] Specifically, a stop platform is arranged on the outer wall of the swing rod 312. When the elastic abutting member 40 is in the initial position, the elastic abutting member 40 is in limit cooperation with the stop platform.

[0098] As Figure 20 and Figure 21 shown, first limiting ribs 151 and second limiting ribs 152 are arranged at intervals on the outer wall of the inner liner 17. The swing rod 312 swings within the range between the first limiting rib 151 and the second limiting rib 152. When the swing rod 312 is in limit cooperation with the first limiting rib 151, the linkage member 31 is in the first position. When the swing rod 312 is in limit cooperation with the second limiting rib 152, the linkage member 31 is in the second position.

[0099] The present application also provides a cooking appliance. The embodiment of the cooking appliance includes a lid assembly, and the lid assembly is the above-mentioned lid assembly. Since the above-mentioned lid assembly can solve the problem of the complex structure of the lid assembly in the related art, the cooking appliance including the above-mentioned lid assembly can solve the same technical problem.

[0100] In this embodiment, the pot body includes a heat preservation cover and an inner pot arranged in the heat preservation cover, and the pot teeth are arranged on the heat preservation cover.

[0101] The cooking appliance in this embodiment is a combined flip-type electric pressure cooker. The pot body further includes a housing arranged outside the heat preservation cover. A hinge structure is arranged between the housing and the lid assembly. A control circuit board is arranged in the housing, and electrical components such as pressure control and temperature measurement are arranged in the outer lid. The combined type setting of the combined flip-type electric pressure cooker facilitates the wired connection between the electrical components in the outer lid and the control circuit board in the housing, ensuring the reliability of the electrical connection.

[0102] Since a hinge structure is arranged between the housing and the lid assembly, when the lid assembly is opened from the pot body, the lid assembly stands on the housing as a whole. At this time, when disassembling the inner lid 20, the user operates the supporting member 63 to move the supporting member 63 from the supporting position to the avoiding position, and pulls the inner lid 20, so that with the insertion block 21 as the swing point, the inner lid 20 swings away from the outer lid 10, and the clamping block 24 is disengaged from the guide groove 13, and the inner lid 20 is inclined relative to the outer lid 10, so as to facilitate taking out the insertion block 21 from the sliding groove 11. Conversely, when installing the inner lid 20 on the outer lid 10, the insertion block 21 is inserted into the sliding groove 11, and the clamping block 24 slides into the guide groove 13.

[0103] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0104] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0105] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0106] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
