[0001] The utility model relates to the technical field of small household appliances, and in particular, 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 an outer cover and an inner cover disposed below the outer cover. A pivot is provided at the central position of the outer cover, and the inner cover is connected to the pivot by means of a nut, so that the pivot and the inner cover are movably connected.

[0004] During the process of connecting the inner cover to the pivot, the pivot hole on the inner cover needs to be aligned with the pivot, so that the pivot passes through the pivot hole and then is connected to the nut to mount the inner cover on the pivot. In this way, since the pivot hole on the inner cover needs to be aligned with the pivot for installation, the assembly is difficult. Summary of the Utility Model

[0005] 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 that the pivot hole on the inner cover in the related art needs to be aligned with the pivot for installation, resulting in difficult assembly.

[0006] To achieve the above object, according to one aspect of the present utility model, there is provided a cover assembly, including: an outer cover, including a first top plate and a first side plate surrounding the edge of the first top plate and extending downward; an inner cover, detachably and rotatably disposed below the outer cover, the inner cover including a second top plate and a second side plate surrounding the edge of the second top plate and extending downward, an insertion and engagement structure and a snap-fit structure are spaced between the first side plate and the second side plate; the insertion and engagement structure includes a first chute and a plug that can slide fit with the first chute; the snap-fit structure includes a second chute and a snap block that can slide fit with the second chute, the second chute is disposed on the first side plate or the second side plate, the snap-fit structure further includes a notch communicating with the second chute, the notch penetrates downward from the second chute to below the outer cover or the inner cover, the snap-fit structure further includes a support member disposed in the notch, the support member is movably disposed and has an avoidance position for avoiding the snap block from entering the second chute and a support position for supporting the snap block to keep the snap block in the second chute; wherein, in the up and down direction of the cover assembly, the size of the first chute is greater than the size of the plug, and the size of the second chute is greater than the size of the snap block.

[0007] Applying the technical solution of the present utility model, during the process of installing the inner cover below the outer cover, after placing the inner cover below the outer cover first, then setting the entire inner cover obliquely relative to the outer cover, inserting the insertion block into the first sliding groove. At this time, swinging towards the outer cover with the plug-in fitting structure as a reference, the supporting member is in the avoidance position, and the clamping block enters the second sliding groove from the notch, so that the inner cover and the outer cover are arranged nearly parallel. When the supporting member is in the supporting position, the clamping block remains in the second sliding groove to install the inner cover below the outer cover. Conversely, the inner cover can be removed from below the outer cover. When the inner cover is installed below the outer cover, the inner cover rotates below the outer cover. At this time, the insertion block rotates in the first sliding groove and is supported and guided by the first sliding groove, and the clamping block rotates in the second sliding groove and is supported and guided by the second sliding groove, so as to facilitate the cover assembly to be closed in place. After the cover assembly is closed in place, since in the up and down direction of the cover assembly, the size of the first sliding groove is larger than the size of the insertion block, and the size of the second sliding groove is larger than the size of the clamping block. The insertion block has a floating space in the first sliding groove, and the clamping block also has a floating space in the second sliding groove, which is convenient for the inner cover to float a certain distance relative to the outer cover after being subjected to the pressure inside the cooking appliance, meeting the upper pressure requirement of the cooking appliance. In this way, there is no need to provide a pivot on the outer cover of the present application, the inner cover can be installed below the outer cover, and the pivot hole for cooperating with the pivot on the inner cover is omitted. Furthermore, it is not necessary to align the inner cover with the pivot for installation, reducing the assembly difficulty. Moreover, the present application inserts the insertion block into the first sliding groove and the clamping block slides into the second sliding groove to install the inner cover below the outer cover, which is easier to assemble. Therefore, the technical solution of the present application effectively solves the problem in the related art that the pivot hole on the inner cover needs to be aligned with the pivot for installation, making the assembly difficult.

[0008] Further, in the up and down direction of the cover assembly, there is a first difference between the size of the first sliding groove and the size of the insertion block, and there is a second difference between the size of the second sliding groove and the size of the clamping block. Both the first difference and the second difference are in the range of 0.5 mm to 6 mm. The above-mentioned first difference and second difference both being in the range of 0.5 mm to 6 mm enables the insertion block to have a sufficiently large floating space in the first sliding groove, and the clamping block also has a sufficiently large floating space in the second sliding groove, which is convenient for the inner cover to float a certain distance relative to the outer cover after being subjected to the pressure inside the cooking appliance, meeting the upper pressure requirement of the cooking appliance.

[0009] Further, the inner cover is circular, and in the circumferential direction of the inner cover, the size of the insertion block is larger than that of the clamping block. In the above structure, since the size of the insertion block is larger than that of the clamping block, it is convenient to distinguish between the insertion block and the clamping block, so that the insertion block can only be inserted into the first chute and cannot be inserted into the second chute, playing an anti-fooling role. And / or, in the up-down direction of the cover assembly, the lower surface of the insertion block chute protrudes downward from the lower surface of the clamping block chute. In this way, there is a height difference between the lower surface of the clamping block chute and the lower surface of the insertion block chute. On the one hand, when the inner cover is installed on the outer cover and the supporting member is in the supporting position, the supporting member is supported below the lower surface of the clamping block chute, lifting the clamping block chute, so that the inner cover is located below the outer cover in a relatively horizontal state, and it is also convenient for the lower groove wall of the second chute to support the clamping block, thereby facilitating the smooth rotation of the inner cover. On the other hand, the thickness of the insertion block chute is relatively thick compared to the thickness of the clamping block chute, and the insertion block chute can improve the structural strength of the inner cover. Further, an exhaust pipe is provided on the first top plate, and an avoidance hole for avoiding the exhaust pipe is provided on the second top plate. The above avoidance hole only avoids the exhaust pipe. Since there is no pivot in the related art on the first top plate, the avoidance hole does not need to be set as a pivot hole that cooperates with the pivot, reducing components and lowering costs.

[0010] Further, the second chute is provided on the first side plate, the clamping block is provided on the second side plate, and the supporting member includes a supporting hook or a buckle. Among them, the supporting hook is movably provided on the first side plate, and the buckle is swingably provided on the first side plate. The above setting of the supporting hook or the buckle facilitates the movement of the supporting member between the avoidance position and the supporting position.

[0011] Further, the supporting hook or the buckle includes a supporting surface provided towards the inside of the notch. When the supporting surface is flush with the lower wall surface of the second chute, the supporting member is in the supporting position. In the above structure, when the clamping block rotates in the second chute, the clamping block can smoothly transition from the supporting surface of the supporting member to the lower wall surface of the second chute, and in the reverse direction, it can smoothly transition from the lower wall surface of the second chute to the supporting surface of the supporting member.

[0012] Further, the cover assembly further includes a handle and a transmission member that are movably provided on the outer cover. A driving column is provided on the inner cover and is threaded through the transmission member. When the handle moves, it drives the transmission member to move, so as to drive the inner cover to rotate below the outer cover through the driving column. In the above structure, the user operates the handle to move, so as to drive the movement of the transmission member, drive the driving column, and drive the inner cover to rotate below the outer cover.

[0013] Further, a stopper is provided on the inner wall of the outer lid, a support surface and an avoidance concave surface are provided on the outer wall of the inner lid, a pot tooth is provided on the pot body of the cooking appliance, and a lid tooth capable of cooperating with the pot tooth is provided on the lower edge of the second side plate. When the inner lid is installed on the outer lid and the lid tooth and the pot tooth are separated, the support surface and the stopper are in a stop cooperation. When the inner lid rotates below the outer lid to engage the lid tooth and the pot tooth together, the avoidance concave surface and the stopper are in an avoidance cooperation. In the above structure, when the inner lid rotates below the outer lid, since the support surface and the stopper are in a stop cooperation, and the insertion block is supported and guided by the first chute, and the locking block is supported and guided by the second chute, the inner lid can rotate in the horizontal plane, preventing tilting and shaking, and avoiding subsequent jamming when the lid tooth and the pot tooth are engaged together.

[0014] Further, the first chute includes an upper side wall and a lower side wall arranged oppositely, the lower side wall is closer to the mouth of the outer lid than the upper side wall, the lid assembly further includes a positioning member provided at the upper side wall. When the inner lid is installed below the outer lid, the insertion block is in a positioning cooperation with the positioning member, and the insertion block is positioned between the positioning member and the lower side wall. In the above structure, the insertion block takes the positioning member as the positioning reference, which facilitates the inner lid to swing with this positioning reference to be installed on the outer lid, prevents the insertion block from sliding in the first chute in the up and down direction, reduces the installation difficulty, and facilitates the inner lid to be smoothly installed on the outer lid.

[0015] According to another aspect of the present invention, a cooking appliance is provided, including a pot body and a lid assembly covering the pot body, and the lid assembly is the above-mentioned lid assembly.

[0016] Further, the pot body includes a heat preservation cover and an inner pot arranged in the heat preservation cover, a pot tooth is provided on the heat preservation cover, and a lid tooth is provided on the lower edge of the second side plate. When the supporting member is in the avoidance position, the locking block slides from the notch into the second chute, and the lid tooth and the pot tooth are separated; when the locking block rotates in the second chute, the lid tooth and the pot tooth are engaged together.

Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0052] Such as Figures 1 to 8aAs shown, the present application provides a cover assembly, and an embodiment of the cover assembly includes: an outer cover 10 and an inner cover 20. The outer cover 10 includes a first top plate 11 and a first side plate 12 that is arranged around the edge of the first top plate 11 and extends downward. The inner cover 20 is detachably and rotatably arranged below the outer cover 10, and the inner cover 20 includes a second top plate 21 and a second side plate 22 that is arranged around the edge of the second top plate 21 and extends downward, and a plug-in mating structure 30 and a snap-in mating structure 40 are arranged at intervals between the first side plate 12 and the second side plate 22. The plug-in mating structure 30 includes a first slide groove 31 and an insert block 32 that can slidably fit with the first slide groove 31. The snap-fit ​​structure 40 includes a second slide groove 41 and a block 42 that can slide with the second slide groove 41. The second slide groove 41 is arranged on the first side plate 12. The snap-fit ​​structure 40 also includes a slot 43 that is connected to the second slide groove 41. The slot 43 runs downward from the second slide groove 41 to the bottom of the outer cover 10. The snap-fit ​​structure 40 also includes a supporting member 44 that is arranged in the slot 43. The supporting member 44 is movably arranged and has a avoiding position to avoid the block 42 from entering the second slide groove 41 and supports the block 42 so that the block 42 remains in the supporting position in the second slide groove 41. In the up-down direction of the cover assembly, the size of the first slide groove 31 is larger than the size of the insert block 32, and the size of the second slide groove 41 is larger than the size of the block 42.

[0053] Applying the technical solution of this embodiment, during the process of installing the inner cover 20 below the outer cover 10, after placing the inner cover 20 below the outer cover 10 first, the entire inner cover 20 is inclined relative to the outer cover 10, and the insertion block 32 is inserted into the first chute 31. At this time, swinging towards the outer cover 10 with the plug-in cooperation structure 30 as a reference, the supporting member 44 is in the avoidance position, and the locking block 42 enters the second chute 41 from the notch 43, so that the inner cover 20 and the outer cover 10 are arranged close to parallel. When the supporting member 44 is in the supporting position, the locking block 42 remains in the second chute 41 to install the inner cover 20 below the outer cover 10. Conversely, the inner cover 20 can be removed from below the outer cover 10. When the inner cover 20 is installed below the outer cover 10, the inner cover 20 rotates below the outer cover 10. At this time, the insertion block 32 rotates in the first chute 31 and is supported and guided by the first chute 31, and the locking block 42 rotates in the second chute 41 and is supported and guided by the second chute 41, so as to facilitate the cover assembly to be closed in place. After the cover assembly is closed in place, since in the up and down direction of the cover assembly, the size of the first chute 31 is larger than the size of the insertion block 32, and the size of the second chute 41 is larger than the size of the locking block 42. The insertion block 32 has a floating space in the first chute 31, and the locking block 42 also has a floating space in the second chute 41, which is convenient for the inner cover 20 to float a certain distance relative to the outer cover 10 after being subjected to the pressure inside the cooking appliance, meeting the upper pressure requirement of the cooking appliance. In this way, there is no need to provide a pivot on the outer cover 10 of this embodiment to install the inner cover 20 below the outer cover 10, and the pivot hole for cooperating with the pivot on the inner cover 20 is omitted. Furthermore, there is no need to align the inner cover 20 with the pivot for installation, reducing the assembly difficulty. Moreover, in this application, the inner cover 20 is installed below the outer cover 10 by inserting the insertion block 32 into the first chute 31 and sliding the locking block 42 into the second chute 41, which is easier to assemble. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the pivot hole on the inner cover needs to be aligned with the pivot for installation, making the assembly difficult.

[0054] In other embodiments, the second chute 41 is provided on the second side plate 22, and the clamping and matching structure 40 further includes a notch 43 communicating with the second chute 41, and the notch 43 penetrates downward from the second chute 41 to below the inner cover 20.

[0055] In this embodiment, the locking block 42 and the insertion block 32 are respectively located on both sides of the inner cover 20. Moreover, the insertion block 32 and the locking block 42 balance and share the gravity of the inner cover 20, so that the inner cover rotates more smoothly, facilitating the insertion block 32 to rotate smoothly in the first chute 31 and the locking block 42 to rotate smoothly in the second chute 41.

[0056] Such as Figures 6 to 8aAs shown, in the up-down direction of the cover body assembly, there is a first difference H1 between the size of the first sliding groove 31 and the size of the insertion block 32, and there is a second difference H2 between the size of the second sliding groove 41 and the size of the locking block 42. Both the first difference H1 and the second difference H2 are in the range of 0.5 mm to 6 mm. The above-mentioned first difference H1 and second difference H2 both being in the range of 0.5 mm to 6 mm enables the insertion block 32 to have a sufficiently large floating space within the first sliding groove 31, and the locking block 42 also has a sufficiently large floating space within the second sliding groove 41, facilitating the inner cover 20 to float a certain distance relative to the outer cover 10 after being subjected to the pressure inside the cooking appliance, meeting the upper pressure requirement of the cooking appliance.

[0057] Preferably, both the above-mentioned first difference H1 and second difference H2 are 0.5 mm or 1 mm or 1.5 mm or 2 mm or 2.5 mm or 3 mm or 4 mm or 5 mm or 6 mm.

[0058] As Figure 2 、 Figure 10 and Figure 11 As shown, the inner cover 20 is circular. In the circumferential direction of the inner cover 20, the size of the insertion block 32 is larger than the size of the locking block 42. In this way, on the one hand, since the size of the insertion block 32 is larger than that of the locking block 42, it is convenient to distinguish between the insertion block 32 and the locking block 42, so that the insertion block 32 can only be inserted into the first sliding groove 31 and cannot be inserted into the second sliding groove 41, playing an anti-fooling role. On the other hand, since the size of the insertion block 32 is larger than that of the locking block 42, after the insertion block 32 is inserted into the first sliding groove 31 first, a stable reference can be formed, facilitating the inner cover 20 to swing towards the outer cover 10, and at the same time facilitating the locking block 42 to smoothly align with the notch 43 so as to enter the second sliding groove 41.

[0059] In this embodiment, in the up-down direction of the inner cover 20, the size of the insertion block 32 is larger than that of the locking block 42, which makes the insertion block 32 thicker. The insertion block 32 is easy to fit on the groove wall of the first sliding groove 31 and is easy to be positioned in the first sliding groove 31, facilitating assembly.

[0060] In the up-down direction of the cover body assembly, the lower surface of the insertion block 32 protrudes downward beyond the lower surface of the locking block 42. In this way, there is a height difference between the lower surface of the locking block 42 and the lower surface of the insertion block 32. On the one hand, when the inner cover is installed on the outer cover and the supporting member is in the supporting position, the supporting member supports below the lower surface of the locking block 42, lifting the locking block 42, so that the inner cover is located below the outer cover in a relatively horizontal state, and it is also convenient for the lower groove wall of the second sliding groove to support the locking block 42, thereby facilitating the inner cover to rotate smoothly. On the other hand, the thickness of the insertion block 32 is thicker than that of the locking block 42, and the insertion block 32 can improve the structural strength of the inner cover.

[0061] As Figure 2 and Figure 10As shown, an exhaust pipe 13 is provided on the first top plate 11, and an avoidance hole 211 for avoiding the exhaust pipe 13 is provided on the second top plate 21. The avoidance hole 211 is preferably a circular hole. In this way, the avoidance hole 211 only avoids the exhaust pipe 13. Since no pivot in the related art is provided on the first top plate 11, the avoidance hole 211 does not need to be set as a pivot hole that cooperates with the pivot, reducing components and costs. Moreover, the exhaust pipe 13 provided on the first top plate 11 will not interfere with the pivot in the related art, and there is no need to adjust the original setting position of the exhaust pipe 13 on the first top plate 11, ensuring the original layout design on the first top plate 11. That is, the cover assembly of the present application only makes structural improvements within a small range and can retain the exhaust pipe 13 and the handle 51 (see below) in their original positions. 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.

[0062] In this embodiment, a pressure limiting valve capable of blocking or opening the exhaust pipe 13 is provided above the exhaust pipe 13.

[0063] As Figures 2 to 8a shown, the second chute 41 is provided on the first side plate 12, and the block 42 is provided on the second side plate 22. In the first embodiment of the supporting member of the cover assembly, the supporting member 44 includes a supporting hook 441 movably provided on the first side plate 12. During the process of the block 42 entering the second chute 41, the block 42 slides into the notch 43 and can squeeze the supporting hook 441. At this time, the supporting member 44 moves from the supporting position to the avoidance position. When the block 42 enters the second chute 41 after passing through the notch 43, the supporting member 44 can move from the avoidance position to the supporting position. At this time, on the one hand, the supporting member 44 blocks the notch 43 to prevent the supporting member 44 from detaching from the second chute 41 through the notch 43. On the other hand, the supporting member 44 supports the block 42 to keep the block 42 in the second chute 41. In this way, the setting of the supporting hook 441 facilitates the movement of the supporting member 44 between the avoidance position and the supporting position. In the first embodiment of the supporting member of the cover assembly, in order to facilitate driving the supporting hook 441, the cover assembly further includes a button 45 movably provided on the outer cover 10. The button 45 is in contact and cooperation with the supporting hook 441 through a driving inclined surface. When the user presses the button 45, the driving inclined surface drives the supporting hook 441 to move, so that the supporting member 44 moves from the supporting position to the avoidance position. The cover assembly further includes a first elastic member 46 provided between the outer cover 10 and the supporting hook 441. The first elastic member 46 applies an elastic force to the supporting hook 441 to keep the supporting member 44 in the supporting position. When the supporting hook 441 no longer receives the pressing force applied by the button 45, under the action of the elastic force of the first elastic member 46, the supporting hook 441 can automatically move towards the supporting position of the supporting member 44, so that the supporting member 44 moves from the avoidance position to the supporting position.

[0064] Specifically, the moving direction of the button 45 is perpendicular to the moving direction of the supporting hook 441 .

[0065] Compared with the detachable inner cover for repairing the cover assembly in the conventional setting, the first embodiment of the supporting member controls the supporting member 44 to move to the supporting position relative to the outer cover 10 through the button 45, and the inner cover 20 can be placed on the supporting member 44, ensuring that the inner cover 20 is installed on the outer cover 10, and the supporting member 44 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 supporting member 44 is controlled by the button 45 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 44 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 44, the supporting member 44 can support the inner cover 20, and the inner cover 20 can rotate relative to the supporting member 44, which guides the rotation of the inner cover 20, thereby improving the structural reliability and practicality of the cover body assembly.

[0066] like Figures 2 to 8a As shown, the supporting hook 441 includes a supporting surface arranged toward the inside of the slot 43, and when the supporting surface is flush with the lower wall surface 411 of the second slide slot 41, the supporting member 44 is in the supporting position. In this way, when the block 42 rotates in the second slide slot 41, the block 42 can smoothly transition from the supporting surface of the supporting member 44 to the lower wall surface 411 of the second slide slot 41, and can smoothly transition from the lower wall surface 411 of the second slide slot 41 to the supporting surface of the supporting member 44 in the opposite direction.

[0067] like Figures 2 to 7 and Figure 8bAs shown, in the second embodiment of the support member of the cover assembly, the support member 44 includes a toggle 442 swingably disposed on the first side plate 12. The user toggles the toggle 442 to swing the support member 44 between the avoidance position and the support position. The cover assembly further includes a second elastic member 47, and the toggle 442 is swingably disposed on the outer cover 10. When the support member 44 is in the support position, the inner cover 20 is placed on the toggle 442. The second elastic member 47 is disposed between the toggle 442 and the outer cover 10 and applies an elastic force towards the inner cover 20 to the toggle 442. With the support member 44 having the above structure, the toggle 442 is swingably disposed on the outer cover 10, and the second elastic member 47 is disposed between the toggle 442 and the outer cover 10. Thus, when the support member 44 is in the support position, under the action of the second elastic member 47, it is ensured that the inner cover 20 is placed on the toggle 442. When disassembling the inner cover 20, the toggle 442 is controlled to swing in a direction away from the inner cover 20, so that the toggle 442 overcomes the elastic force of the second elastic member 47, thereby ensuring that the inner cover 20 is disengaged from the toggle 442, and then the toggle 442 is reset under the elastic force of the second elastic member 47. The operation method is simple, achieving one-key quick disassembly and easy disassembly. The toggle 442 includes a support surface disposed towards the inside of the notch 43.

[0068] As Figures 9 to 21 shown, the cover assembly further includes a handle 51 and a transmission member 52 movably disposed on the outer cover 10. A driving post 212 penetrating through the transmission member 52 is provided on the inner cover 20. When the handle 51 moves, it drives the transmission member 52 to move, so as to drive the inner cover 20 to rotate below the outer cover 10 through the driving post 212. In this way, the user operates the handle 51 to move, so as to drive the movement of the transmission member 52 to drive the driving post 212 to drive the inner cover 20 to rotate below the outer cover 10.

[0069] It should be noted that, in this embodiment, the transmission member 52 moves by being driven by the handle 51. In other embodiments, the transmission member 52 moves by being driven by a driving motor, and a trigger switch is provided on the cooking appliance for turning on or off the driving motor.

[0070] In the present application, the transmission member 52 includes a sliding plate or a swing rod. When operating the handle 51 to move, the handle 51 can drive the sliding plate to move to drive the driving post 212 to rotate. Or when operating the handle 51 to move, the handle 51 can drive the swing rod to swing on a horizontal plane to drive the driving post 212 to rotate. In the present application, during the process of installing the inner cover 20 below the outer cover 10, the entire inner cover 20 needs to be inclined relative to the outer cover 10 first, and then the insertion block 32 is inserted into the first chute 31. After that, the inner cover 20 is more likely to be inclined. For the convenience of installation, the inner cover 20 needs to be restricted within a certain inclination range to achieve inclined installation.

[0071] AsFigures 1 to 10 , Figure 21 and Figure 22 As shown, the transmission member 52 has a first position and a second position. The lower edge of the inner cover 20 is provided with a cover tooth 23 that cooperates with the pot tooth of the pot body of the cooking utensil. When the transmission member 52 is in the first position, the inner cover 20 is in an unlocked state, and when the transmission member 52 is in the second position, the inner cover 20 is in a locked state. The cover assembly also includes an elastic push-up member 63 that is movably arranged on the outer cover 10. The elastic push-up member 63 has an initial position that limits the transmission member 52 to the first position and a avoidance position that avoids the transmission member 52 so that the transmission member 52 can move. When the inner cover 20 is installed below the outer cover 10, the inner cover 20 abuts and cooperates with the elastic push-up member 63, so that the elastic push-up member 63 moves from the initial position to the avoidance position, and the inner cover 20 can float up and down.

[0072] like Figures 1 to 10 , Figure 21 and Figure 22As shown, when the user operates the handle 51 to move and drives the transmission member 52 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 pushing member 63 limits the transmission member 52 at the initial position of the first position, it prevents the user from accidentally operating the handle 51 and changing the position of the transmission member 52, 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, first tilt the inner cover 20 relative to the outer cover 10, insert the insertion block 32 into the first chute 31, and then install the inner cover 20 below the outer cover 10. And, the inner cover 20 will push against the elastic pushing member 63 and abut and cooperate with the elastic pushing member 63, so that the elastic pushing member 63 moves from the initial position to the avoiding position. The user can operate the handle 51 to move again, so that the transmission member 52 can be switched between the first position and the second position, facilitating 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 and cooperates with the elastic pushing member 63, the elastic pushing member 63 can apply pressure to the inner cover 20, which can overcome the possible tilt of the inner cover 20, facilitating the rotation of the inner cover 20 in the horizontal direction, thus 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 first chute 31 is greater than the dimension of the insertion block 32 along the width direction of the first chute 31, as the pressure inside the cooking appliance increases (i.e., upward pressure), the inner cover 20 can overcome the pressure applied by the elastic pushing member 63 to the inner cover 20 and float smoothly upward, and the insertion block slides upward in the chute along the floating direction of the inner cover 20. Therefore, in the first embodiment, only the elastic pushing member 63 needs to be designed to be able to play a limiting role and an anti-deviation role, and moreover, as the cooking appliance is under upward pressure, the inner cover 20 can float smoothly up and down. 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.

[0073] As Figures 1 to 10 , Figure 21 and Figure 22As shown, the elastic ejector 63 includes a push rod 631 and a third elastic member 632. A guide hole for guiding the push rod 631 is provided on the outer cover 10. The push rod 631 includes a rod body 6311 passing through the guide hole and a block 6312 connected to the rod body 6311. The inner cover 20 can be in abutting cooperation with the rod body 6311. When the inner cover 20 is separated from the rod body 6311 and the block 6312 is in limit cooperation with the transmission member 52, the elastic ejector 63 is in the initial position; when the inner cover 20 is in abutting cooperation with the rod body 6311 and the block 6312 is in avoidance cooperation with the transmission member 52, the elastic ejector 63 is in the avoidance position. With the elastic ejector 63 having the above structure, the elastic ejector 63 is inserted into the guide hole, which facilitates the installation of the elastic ejector 63 and guides the movement of the elastic ejector 63 relative to the inner liner 14, enabling the elastic ejector 63 to move smoothly and reliably between the initial position and the avoidance position.

[0074] As Figures 1 to 10 , Figure 21 and Figure 22 shown, the third elastic member 632 is arranged between the outer cover 10 and the elastic ejector 63, and the third elastic member 632 applies an elastic force to the elastic ejector 63 to keep the elastic ejector 63 in the initial position. When the inner cover 20 is disassembled, the inner cover 20 is separated from the elastic ejector 63, and the elastic ejector 63 is acted on by the elastic force of the third elastic member 632, so that the transmission member 52 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 ejector 63 restricts the movement of the transmission member 52, making the handle 51 inoperable and the cover assembly unable to close (i.e., switch from the locked state to the unlocked state), avoiding the operation of closing the cover when the inner cover 20 is missing.

[0075] It should be noted that the number of the elastic ejectors 63 can be one or more.

[0076] When multiple elastic ejectors 63 are arranged at intervals around the axis of the outer cover 10. Multiple elastic ejectors 63 are all in abutting contact with the outer top wall of the inner cover 20, enabling the inner cover 20 to float relative to the pot body in a direction approaching or away from the outer cover 10. Thus, during the process of the cover assembly being placed on the pot body and the inner cover 20 rotating relative to the outer cover 10, the elastic expansion and contraction of the multiple elastic ejectors 63 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 cooking, with the change of pressure inside the cooking appliance, the elastic expansion and contraction of the multiple elastic ejectors 63 are utilized to make the inner cover 20 float relative to the pot body in a direction approaching or away from the outer cover 10.

[0077] When one elastic ejector 63 is arranged on the outer cover and is located on the side close to the insertion block 32, the insertion block of the inner cover can rotate along the chute, avoiding the tilting of the inner cover 20.

[0078] When an elastic ejector 63 is set at a position away from both the insert block and the clamp block, the three components formed by the elastic ejector 63, the insert block and the clamp block (see below) keep the inner cover rotating on a plane and can also prevent the inner cover 20 from tilting.

[0079] When the inner cover 20 is circular, an elastic push piece 63 is arranged on the outer cover. In the circumferential direction of the inner cover 20, the elastic push piece 63 is spaced apart from the first slide groove 31. When the inner cover 20 rotates relative to the outer cover 10 and the plug block 32 slides in the first slide groove 31 along the rotation direction, since the elastic push piece 63 is spaced apart from the first slide groove 31, the pressure applied by the elastic push piece 63 to the inner cover 20 keeps the plug block 32 in a state of sliding in the first slide groove 31 along the rotation direction, so that the inner cover 20 can rotate smoothly.

[0080] like Figures 9 to 20 As shown, in this embodiment, a stopper 61 is provided on the inner wall of the outer cover 10, and a support surface 213 and a avoidance concave surface 214 are provided on the outer wall of the inner cover 20. Pot teeth are provided on the pot body of the cooking utensil, and a cover tooth 23 capable of cooperating with the pot teeth is provided on the lower edge of the second side plate 22. When the inner cover 20 is installed on the outer cover 10, and the cover tooth 23 and the pot teeth are separated (that is, the inner cover 20 is in an unlocked state), the support surface 213 and the stopper 61 are engaged. At this time, the insert block 32 is inserted into the first slide groove 31 and abuts against the lower wall surface of the first slide groove 31, so that the inner cover 20 is restricted between the stopper 61 and the lower wall surface of the first slide groove 31, thereby limiting the tilting range of the inner cover 20, and when the inner cover 20 is straightened so that the block 42 enters the second slide groove 41, the inner cover 20 is approximately installed horizontally below the outer cover 10. When the inner cover 20 rotates under the outer cover 10, the support surface 213 cooperates with the stopper 61, and the insert block 32 is supported and guided by the first slide groove 31, and the block 42 is supported and guided by the second slide groove 41, so that the inner cover 20 can rotate in the horizontal plane to prevent tilting and shaking, and avoid the subsequent cover teeth 23 and pot teeth from being stuck together. When the cover teeth 23 and the pot teeth are buckled together (that is, the inner cover 20 is in a locked state), the avoidance concave surface 214 and the stopper 61 are avoided. In this case, when the cooking utensil is pressed upward, the pressure in the cooking utensil will push the inner cover 20 to float upward relative to the outer cover 10. The avoidance cooperation relationship between the avoidance concave surface 214 and the stopper 61 can prevent the stopper 61 from interfering with the inner cover 20, so that the inner cover 20 can float smoothly. The stopper 61 is preferably a stop rib.

[0081] like Figures 2 to 4 and Figure 10As shown, the first slide groove 31 includes an upper side wall 311 and a lower side wall 312 that are arranged opposite to each other, and the lower side wall 312 is closer to the mouth of the outer cover 10 than the upper side wall 311. The cover body assembly also includes a positioning member 62, which is arranged at the upper side wall 311. When the inner cover 20 is installed below the outer cover 10, the plug block 32 is positioned and matched with the positioning member 62, and the plug block 32 is positioned between the positioning member 62 and the lower side wall 312. In this way, the plug block 32 uses the positioning member 62 as a positioning reference, so that the inner cover 20 can swing according to this positioning reference to be installed on the outer cover 10, and the plug block 32 is prevented from sliding in the up and down directions in the first slide groove 31, which reduces the difficulty of installation, so that the inner cover 20 can be smoothly installed on the outer cover 10, thereby improving the efficiency of installation. Specifically, the positioning member 62 is arranged on the upper side wall 311. The positioning member 62 is preferably a positioning rib.

[0082] In this embodiment, the outer cover 10 includes an inner liner 14 located above the inner cover 20 and a surface cover 15 disposed above the inner liner 14, the inner liner 14 is clamped on the surface cover 15, and the first top plate 11 and the first side plate 12 are both located on the inner liner 14. The inner cover 20 includes a pot cover and an outer cover disposed above the pot cover, the outer cover is clamped on the pot cover, and the clamping block 42 and the inserting block 32 on the second top plate 21 and the second side plate 22 are both located on the outer cover. The cover teeth on the second side plate 22 are located on the pot cover. The outer cover is preferably a plastic part.

[0083] In this embodiment, in the up-down direction of the cover assembly, the lower surface of the insert block 32 protrudes downward from the lower surface of the clamp block 42. In this way, the thickness of the insert block 32 is thicker than that of the clamp block 42, and the insert block 32 can improve the structural strength of the inner cover, and it is convenient to provide a connecting structure (such as a threaded hole) on the insert block 32, so that the outer cover can be connected to the connecting structure by fasteners (such as screws) and installed together with the pot cover.

[0084] The present application also provides a cooking utensil, comprising a pot body and a cover assembly disposed on the pot body, the cover assembly being the above-mentioned cover assembly. Since the above-mentioned cover assembly can solve the problem in the related art that the pivot hole on the inner cover must be aligned with the pivot for installation, making assembly difficult, the cooking utensil comprising the cover assembly can solve the same technical problem.

[0085] In this embodiment, the pot body includes a heat-insulating cover and an inner pot arranged in the heat-insulating cover, the heat-insulating cover is provided with pot teeth, and the lower edge of the second side plate 22 is provided with cover teeth 23. In this way, the plug-in matching structure 30 and the snap-fit ​​matching structure 40 are used to match the cover teeth 23 and the pot teeth for separation or snap-fit. When the supporting member 44 is in the avoidance position, the clamping block 42 slides from the notch 43 into the second slide groove 41, and the cover teeth 23 and the pot teeth are separated. When the clamping block 42 rotates in the second slide groove 41, the cover teeth 23 and the pot teeth are snap-fitted together.

[0086] Specifically, when applying the technical solution of this embodiment, during the process of installing the inner lid 20 below the outer lid 10, after placing the inner lid 20 below the outer lid 10 first, the entire inner lid 20 is inclined relative to the outer lid 10, and the insertion block 32 is inserted into the first sliding groove 31. At this time, swinging towards the outer lid 10 with the plug-in cooperation structure 30 as a reference, the supporting member 44 is in the avoidance position, and the clamping block 42 enters the second sliding groove 41 from the notch 43, so that the inner lid 20 and the outer lid 10 are arranged almost parallel to each other. At this time, the supporting surface 213 is in a stop cooperation with the stopper 61, and the lid teeth 23 and the pot teeth are separated. At this time, the position of the inner lid on the outer lid 10 is as Figures 13 to 16 shown. Then, after the inner lid 20 rotates a preset angle H3 (the preset angle H3 is preferably 30 degrees) below the outer lid 10, the lid teeth 23 and the pot teeth are buckled together, and the avoidance concave surface 214 is in an avoidance cooperation with the stopper 61. At this time, the position of the inner lid on the outer lid 10 is as Figures 17 to 20 shown.

[0087] The cooking appliance of 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 cover assembly. A control circuit board is arranged inside the housing, and electrical components such as pressure control and temperature measurement are arranged inside the outer lid. The combined setting of the combined flip-type electric pressure cooker facilitates the wired connection between the electrical components inside the outer lid and the control circuit board inside the housing, ensuring the reliability of the electrical connection.

[0088] Since a hinge structure is arranged between the housing and the cover assembly, when the cover assembly is opened from the pot body, the cover assembly stands on the housing as a whole. At this time, the user operates the supporting member 44 to move the supporting member 44 from the supporting position to the avoidance position, facilitating the inner lid to fall from the outer lid, so as to quickly and easily remove the inner lid from the outer lid.

[0089] Of course, in other embodiments, the cooking appliance can also be products such as rice cookers, low-pressure rice cookers, soybean milk machines, cooking machines, stir-fry machines, electric stew pots, and multi-functional pots.
