[0004] However, with the structure in the related art, the cover body assembly has the problem of complex structure. Summary of the Utility Model

[0005] The utility model provides an inner cover, a cover body assembly and a cooking appliance to solve the problem of complex structure of the cover body assembly in the related art.

[0006] According to one aspect of the utility model, an inner cover is provided. The inner cover includes a first top plate and a first side plate surrounding the edge of the first top plate and extending downward. An insertion block capable of being inserted and matched with the outer cover and a clamping block capable of being clamped and matched with the outer cover are arranged on the first side plate. Both the clamping block and the insertion block are integrally formed with the first side plate. A cover tooth capable of being matched with the pot tooth is arranged on the lower edge of the first side plate.

[0007] By applying the inner cover provided in this embodiment, the inner cover includes a first top plate and a first side plate. The first side plate is arranged on the edge of the first top plate and extends downward. An insertion block and a clamping block are arranged on the first side plate. When the inner cover is installed on the outer cover, after the insertion block is inserted and matched with the outer cover, the clamping block is clamped and matched with the outer cover, so as to facilitate the installation of the inner cover on the outer cover and ensure the convenience of disassembly and assembly of the inner cover. And a cover tooth matched with the pot tooth is arranged on the lower edge of the first side plate. After the inner cover is assembled on the outer cover, the cover tooth on the inner cover can be matched with the pot tooth, so as to ensure that the inner cover can play a pressure-bearing role. Moreover, the first side plate, the insertion block and the clamping block are integrally formed, which is convenient for the production and manufacture of the inner cover and can also facilitate the integration of the inner cover and the lock ring in the prior art into an integrated structure. Therefore, the technical solution of this application effectively solves the problem of complex structure of the cover body assembly in the related art.

[0008] Furthermore, the first top plate and the first side plate are of an integrally formed structure. By making the first top plate and the first side plate of an integrally formed structure, it is convenient to manufacture the inner lid.

[0009] Furthermore, a positioning shaft is provided on the insertion block and / or the clamping block, and a sealing ring limiting groove is formed between the positioning shaft and the first top plate; the convex block on the inner lid that was originally only used for inserting the sealing ring is now also used for arranging the insertion block and the clamping block. Thus, not only can the insertion block be used for plugging and matching with the outer lid and the clamping block be used for clamping and matching with the outer lid, but also the positioning shaft provided on the insertion block and / or the clamping block can be used to fix the sealing ring. Moreover, by utilizing the original structure with steel needles, the structure, processing cost, and process of the inner lid are less affected, enabling the relevant structure for fixing the steel needles on the original inner lid to have a new function. Only the dimensions of the original structure are changed, and no new process steps are added. And / or, the inner lid is a metal lid. By setting the inner lid as a metal lid, when the inner lid is installed on the outer lid, it can ensure that the inner lid can play a role in cooking under pressure and enhance the structural strength of the inner lid.

[0010] Furthermore, the clamping blocks and the insertion blocks are arranged at intervals along the circumferential direction of the first side plate. By arranging the clamping blocks and the insertion blocks at intervals along the circumferential direction of the first side plate, it is convenient to perform the clamping and matching between the clamping blocks and the outer lid, and also convenient to perform the plugging and matching between the insertion blocks and the outer lid, thereby ensuring the installation of the inner lid on the outer lid.

[0011] Furthermore, the first top plate has an exhaust pipe avoidance hole penetrating through it. With the above structure, an exhaust pipe avoidance hole is penetratingly provided on the first top plate, so as to ensure that the exhaust pipe can pass through the exhaust pipe avoidance hole and be arranged in the inner lid, ensuring that the cooking function can be realized by using the exhaust pipe.

[0012] According to another aspect of the present invention, there is provided a lid assembly covering the pot body of a cooking appliance. The lid assembly includes: an outer lid including a second top plate and a second side plate surrounding the edge of the second top plate and extending downward; an inner lid detachably and rotatably arranged below the outer lid. An insertion and matching structure and a clamping and matching structure are spaced between the second side plate and the first side plate of the inner lid. The inner lid is the inner lid provided above; the insertion and matching structure includes a first sliding groove provided on the outer lid and an insertion block provided on the inner lid, and the insertion block is slidably matched with the first sliding groove; the clamping and matching structure includes a second sliding groove provided on the outer lid and a clamping block provided on the inner lid, and the clamping block is slidably matched with the second sliding groove. The clamping and matching structure further includes a notch, the notch penetrating the lower wall surface of the second sliding groove and the bottom surface of the second side plate. The clamping and matching structure further includes a supporting member arranged in the notch, the supporting member being movably arranged and having an avoidance position for avoiding the clamping block from entering the second sliding groove and a supporting position for supporting the clamping block to keep the clamping block in the second sliding groove.

[0013] By applying the technical solution of the utility model, during the process of installing the inner cover below the outer cover, the inner cover is first placed below the outer cover, and then the entire inner cover is tilted relative to the outer cover, and the plug block is inserted into the first slide groove. At this time, the plug-in matching structure is used as a reference to swing toward the outer cover, the supporting member is in an avoidance position, and the block enters the second slide 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 block remains in the second slide groove, so that the inner cover is installed below the outer cover. On the contrary, 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, and at this time the plug block rotates in the first slide groove and is supported and guided by the first slide groove, and the block rotates in the second slide groove and is supported and guided by the second slide groove, so that the cover assembly can be covered in place. The plug-in structure and the snap-fit ​​structure are formed as an integral structure with the first side panel, which can reduce costs. Moreover, under the action of the inner cover, it is convenient to install the inner cover on the outer cover, and it is also convenient to clean the inner cover and the outer cover when the inner cover is removed from the outer cover to avoid the accumulation of food residues. In this way, the outer cover of the present application does not need to be provided with a pivot, so the inner cover can be installed below the outer cover, and the pivot hole provided on the inner cover to cooperate with the pivot is omitted, so that the inner cover does not need to be aligned with the pivot for installation, which reduces the difficulty of assembly. Moreover, the present application inserts the plug block into the first slide groove, and the card block slides into the second slide groove to realize the installation of the inner cover below the outer cover, which is easier to assemble. Therefore, the technical solution of the present application effectively solves the problem of complex structure of the cover assembly in the related art.

[0014] Furthermore, the rear end of the outer cover has a hinged portion hinged to the pot body, the first slide groove is arranged at the rear end of the second side plate, and the second slide groove is arranged at the front end of the second side plate; adopting the above structure, the outer cover can be rotated relative to the pot body under the action of the hinged portion, thereby realizing the lid opening or closing operation, the first slide groove is arranged at the rear end of the second side plate, and the second slide groove is arranged at the front end of the second side plate, thereby making the first slide groove match the plug block, and the second slide groove match the card block, ensuring that when the plug block is inserted into the first slide groove, the card block can extend into the second slide groove through the slot, and it can also facilitate the inner cover to rotate relative to the outer cover, avoid the inner cover from being separated from the outer cover, and ensure that the inner cover can realize the pressure bearing effect. In addition, when the cover assembly is opened from the pot body, the cover assembly stands on the outer shell as a whole. At this time, the user operates the supporting member to make the supporting member move from the supporting position to the avoidance position, so that the inner cover can fall off from the outer cover, so as to realize the removal of the inner cover from the outer cover. And / or, the outer cover includes a surface cover and an inner liner located below the surface cover, and the inner liner includes a second top plate and a second side plate. With the above structure, the inner liner is clamped on the surface cover, and the second top plate and the second side plate are both located on the inner liner, which is convenient for manufacturing the inner liner.

[0015] Further, a stopper is provided on the inner wall of the outer lid, and a support surface and an avoidance concave surface are provided on the outer wall of the inner lid. When the inner lid is installed on the outer lid and the lid teeth of the inner lid are separated from the pot teeth, the support surface and the stopper are in a stop fit. When the inner lid rotates below the outer lid to engage the lid teeth and the pot teeth together, the avoidance concave surface and the stopper are in an avoidance fit. At this time, the insertion block is inserted into the first chute and abuts against the lower wall surface of the first chute. In this way, the inner lid is restricted between the stopper and the lower wall surface, thereby restricting the tilting range of the inner lid. After the inner lid is righted so that the locking block enters the second chute, the inner lid is installed approximately horizontally below the outer lid. When the inner lid rotates below the outer lid, since the support surface and the stopper are in a stop fit, 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 of the lid teeth and the pot teeth when they are engaged together. When the lid teeth and the pot teeth are engaged together, the avoidance concave surface and the stopper are in an avoidance fit. In this case, when there is an upward pressure inside the cooking appliance, the pressure inside the cooking appliance will push the inner lid to float upward relative to the outer lid. The avoidance fit relationship between the avoidance concave surface and the stopper can prevent the stopper from interfering with the inner lid, enabling the inner lid to float smoothly. The stopper is preferably a stop rib.

[0016] Further, in the up-down direction of the lid assembly, the size of the first chute is larger than the size of the insertion block, and the size of the second chute is larger than the size of the locking block; and / or, an anti-misassembly structure is provided between the outer lid and the inner lid so that the insertion block is inserted into the first chute and the locking block is inserted into the second chute. With the above structure, after the lid assembly is closed in place, since in the up-down direction of the lid assembly, the size of the first chute is larger than the size of the insertion block, and the size of the second chute is larger than the size of the locking block, there is a floating space for the insertion block in the first chute and there is also a floating space for the locking block in the second chute, facilitating the inner lid to float a certain distance relative to the outer lid after being subjected to the pressure inside the cooking appliance, meeting the upward pressure requirement of the cooking appliance. By providing the anti-misassembly structure, it can be ensured that the insertion block is inserted into the first chute and the locking block is inserted into the second chute, avoiding incorrect installation of the inner lid on the outer lid, which may cause the failure to achieve the pressure-bearing function.

[0017] According to another aspect of the present invention, a cooking appliance is provided, which includes: a pot body; and a lid assembly that can be opened and closed to cover the pot body, and the lid assembly is the lid assembly provided above. Since the above lid assembly can solve the problem in the related art that the pivot hole on the inner lid needs to be aligned with the pivot for installation, making the assembly difficult, the cooking appliance including this lid assembly can solve the same technical problem.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation to the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] As Figures 1 to 10 shown, the embodiment of the present invention provides an inner cover, which includes a first top plate 21 and a first side plate 22 surrounding the edge of the first top plate 21 and extending downward. The first side plate 22 is provided with a plug 32 that can be plugged and matched with the outer cover and a snap 42 that can be snap-fitted with the outer cover. Both the snap 42 and the plug 32 are integrally formed with the first side plate 22. The lower edge of the first side plate 22 is provided with a cover tooth 221 that can be matched with the pot tooth.

[0040] When applying the inner cover provided in this embodiment, the inner cover includes a first top plate 21 and a first side plate 22. The first side plate 22 is arranged at the edge of the first top plate 21 and extends downward. A plug 32 and a snap 42 are arranged on the first side plate 22. In this way, when the inner cover is installed on the outer cover, after the plug 32 is plugged and matched with the outer cover, the snap 42 is snap-fitted with the outer cover, which is convenient for installing the inner cover on the outer cover and ensures the convenience of disassembling and assembling the inner cover. And a cover tooth 221 that matches the pot tooth is arranged at the lower edge of the first side plate 22. After the inner cover is assembled on the outer cover, the cover tooth 221 on the inner cover can be matched with the pot tooth, so as to ensure that the inner cover can play a pressure-bearing role. Moreover, the first side plate 22, the plug 32 and the snap 42 are arranged in an integrally formed structure, which is convenient for manufacturing the inner cover and can also facilitate integrating the inner cover and the lock ring in the prior art into an integrated structure. Therefore, the technical solution of this application effectively solves the problem of the complex structure of the cover assembly in the related art.

[0041] As Figure 2 、Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, the first top plate 21 and the first side plate 22 are integrally formed structures. By making the first top plate 21 and the first side plate 22 integrally formed structures, it is convenient to manufacture the inner cover.

[0042] As Figure 2 and Figure 3 shown, a positioning shaft 61 is provided on the insertion block 32 and / or the clamping block 42, and a sealing ring limiting groove 62 is formed between the positioning shaft 61 and the first top plate 21. The original convex block on the inner cover that was only used to insert the sealing ring 63 is now also used to set the insertion block 32 and the clamping block 42. Furthermore, the insertion block 32 can be used to perform insertion fit with the outer cover and the clamping block 42 can be used to perform clamping fit with the outer cover, and the positioning shaft 61 provided on the insertion block 32 and / or the clamping block 42 can be used to fix the sealing ring 63. Moreover, by using the original structure with steel needles, the structure, processing cost and process of the inner cover are less affected, enabling the original structure related to fixing the steel needles on the inner cover to have new functions, only changing the dimensions of the original structure without adding new process steps.

[0043] In this embodiment, positioning shafts 61 are provided on both the insertion block 32 and the clamping block 42.

[0044] It should be noted that, as Figures 2 to 4 shown, the positioning shaft 61 is a straight section extending along its axis. In this way, after the positioning shaft 61 is processed by cutting, there is no need for further bending or flattening treatment, which not only simplifies the processing technology and reduces the labor cost. Moreover, when the positioning shaft 61 passes through the insertion block 32 and / or the clamping block 42, the first end of the positioning shaft 61 can be inserted first, or the second end of the positioning shaft 61 can be inserted first, or it can be inserted from any one of the left and right directions, enriching the installation methods of the positioning shaft 61, making the installation more intuitive, facilitating assembly, and being conducive to improving the installation efficiency. The positioning shaft 61 is preferably a steel needle. A sealing ring 63 is provided on the inner cover, and a buckling portion 631 protruding outward is provided on the outer edge of the sealing ring 63, and the buckling portion 631 is inserted into the sealing ring limiting groove 62. In this way, it is convenient to reliably limit the sealing ring 63 inside the inner cover.

[0045] It should be noted that the "multiple" in this application includes at least two.

[0046] In this embodiment, the inner cover is a metal cover. By setting the inner cover as a metal cover, when the inner cover is installed on the outer cover, it is ensured that the inner cover can play a role in cooking pressure resistance and improve the structural strength of the inner cover.

[0047] As Figure 2 , Figure 6 , Figure 7, Figure 8 , Figure 9 and Figure 10 As shown in Figure 10 , the clamping blocks 42 and the inserting blocks 32 are arranged at intervals along the circumferential direction of the first side plate 22. By arranging the clamping blocks 42 and the inserting blocks 32 at intervals along the circumferential direction of the first side plate 22, it is convenient to perform clamping fit between the clamping blocks 42 and the outer cover, and it is also convenient to perform inserting fit between the inserting blocks 32 and the outer cover, thereby ensuring that the inner cover is installed on the outer cover.

[0048] As Figure 9 shown in Figure 9 , the first top plate 21 has an exhaust pipe avoiding hole 211 penetrating therethrough. With the above structure, the exhaust pipe avoiding hole 211 is penetratingly arranged on the first top plate 21, thereby ensuring that the exhaust pipe can pass through the exhaust pipe avoiding hole 211 and penetrate through the inner cover, and ensuring that the cooking function can be realized by using the exhaust pipe.

[0049] As Figures 1 to 10 shown in Figures 1 to 10 , an embodiment of the present utility model provides a cover assembly, which is covered on the pot body of a cooking appliance. The cover assembly includes an outer cover 10 and an inner cover 20. The outer cover 10 includes a second top plate 11 and a second side plate 12 surrounding the edge of the second top plate 11 and extending downward. The inner cover 20 is detachably and rotatably arranged below the outer cover 10. An inserting and fitting structure 30 and a clamping and fitting structure 40 are arranged at intervals between the second side plate 12 and the first side plate 22 of the inner cover 20. The inner cover 20 is the inner cover provided above. The inserting and fitting structure 30 includes a first sliding groove 31 arranged on the outer cover 10 and an inserting block 32 arranged on the inner cover 20. The inserting block 32 is slidably fitted with the first sliding groove 31. The clamping and fitting structure 40 includes a second sliding groove 41 arranged on the outer cover 10 and a clamping block 42 arranged on the inner cover 20. The clamping block 42 is slidably fitted with the second sliding groove 41. The clamping and fitting structure 40 further includes a notch 43, and the notch 43 penetrates the lower wall surface of the second sliding groove 41 and the bottom surface of the second side plate 12. The clamping and fitting structure 40 further includes a supporting member 44 arranged in the notch 43. The supporting member 44 is movably arranged and has an avoiding position for avoiding the clamping block 42 from entering the second sliding groove 41 and a supporting position for supporting the clamping block 42 to keep the clamping block 42 in the second sliding groove 41.

[0050] When the cover assembly provided by the present embodiment is used, the inner cover 20 is installed below the outer cover 10. First, the inner cover 20 is placed below the outer cover 10, and then the entire inner cover 20 is tilted relative to the outer cover 10, and the plug block 32 is inserted into the first slide groove 31. At this time, the plug-in matching structure 30 is used as a reference to swing toward the outer cover 10, and the supporting member 44 is in the avoidance position. The block 42 enters the second slide groove 41 from the slot 43, so that the inner cover 20 and the outer cover 10 are arranged nearly parallel. When the supporting member 44 is in the supporting position, the block 42 remains in the second slide groove 41, so that the inner cover 20 is installed below the outer cover 10. On the contrary, the inner cover 20 can be removed from the bottom of the outer cover 10. When the inner cover 20 is installed under the outer cover 10, the inner cover 20 rotates under the outer cover 10, and the plug block 32 rotates in the first slide groove 31 and is supported and guided by the first slide groove 31, and the clamp block 42 rotates in the second slide groove 41 and is supported and guided by the second slide groove 41, so that the cover assembly can be covered in place. The plug-in matching structure and the part of the clamping matching structure 40 arranged on the first side plate 22 are integrally formed with the first side plate 22, which can reduce costs, and under the action of the inner cover 20, it is convenient to install the inner cover 20 on the outer cover 10, and it is also convenient to clean the inner cover 20 and the outer cover 10 when the inner cover 20 is removed from the outer cover 10 to avoid accumulation of food residues. In this way, the outer cover 10 of the present application does not need to be provided with a pivot, and the inner cover 20 can be installed below the outer cover 10, and the pivot hole that matches the pivot is omitted on the inner cover 20, so that the inner cover 20 does not need to be aligned with the pivot for installation, which reduces the difficulty of assembly. In addition, the present application inserts the insert block 32 into the first slide groove 31, and the clamp block 42 slides into the second slide groove 41 to achieve the method of installing the inner cover 20 below the outer cover 10, which is easier to assemble. Therefore, the technical solution of the present application effectively solves the problem of complex structure of the cover assembly in the related art.

[0051] It should be noted that the first sliding groove 31 and the second sliding groove 41 can be two independent grooves, or can be a two-section structure of a groove.

[0052] In this embodiment, in order to ensure that the inner cover 20 is stably installed below the outer cover 10 , the clamping block 42 and the inserting block 32 are respectively located on both sides of the inner cover 20 .

[0053] It should be noted that, in other embodiments, the supporting member 44 includes a supporting hook that is swingably disposed on the second side plate 12 , and the user moves the supporting hook to make the supporting member 44 swing between the avoidance position and the supporting position.

[0054] like Figure 11 and Figure 12As shown, the rear end of the outer cover 10 has a hinged portion hinged to the pot body, the first slide groove 31 is arranged at the rear end of the second side plate 12, and the second slide groove 41 is arranged at the front end of the second side plate 12. With the above structure, the outer cover 10 can be rotated relative to the pot body under the action of the hinged portion, thereby realizing the cover opening or closing operation, the first slide groove 31 is arranged at the rear end of the second side plate 12, and the second slide groove 41 is arranged at the front end of the second side plate 12, so that the first slide groove 31 can match the plug block 32, and the second slide groove 41 can match the clamping block 42, ensuring that when the plug block 32 is inserted into the first slide groove 31, the clamping block 42 can extend into the second slide groove 41 through the slot 43, and can also facilitate the inner cover 20 to rotate relative to the outer cover 10, preventing the inner cover 20 from being separated from the outer cover 10, and ensuring that the inner cover 20 can achieve the pressure-bearing effect. Furthermore, when the cover assembly is opened from the pot body, the cover assembly stands as a whole on the outer shell. At this time, the user operates the supporting member 44 to move the supporting member 44 from the supporting position to the avoiding position, so as to facilitate the inner cover to fall from the outer cover, thereby realizing the removal of the inner cover 20 from the outer cover 10.

[0055] like Figure 4 As shown, the outer cover 10 includes a surface cover 13 and an inner lining 14 located below the surface cover 13, and the inner lining 14 includes a second top plate 11 and a second side plate 12. With the above structure, the inner lining 14 is clamped on the surface cover 13, and the second top plate 11 and the second side plate 12 are both located on the inner lining 14, which is convenient for manufacturing the inner lining 14.

[0056] like Figure 4 , Figure 11 as well as Figure 12 As shown, the pot body of the cooking utensil is provided with pot teeth, and the lower edge of the first side plate 22 is provided with a cover tooth 221 that can cooperate with the pot teeth. With the above structure, the plug-in matching structure 30 and the snap-fit ​​matching structure 40 are used to match the cover tooth 221 and the pot teeth for separation or buckling. 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 tooth 221 and the pot teeth are separated. When the clamping block 42 rotates in the second slide groove 41, the cover tooth 221 and the pot teeth are buckled together.

[0057] like Figures 6 to 12As shown, a stopper 51 is provided on the inner wall of the outer cover 10, and a support surface 23 and an avoidance concave surface 24 are provided on the outer wall of the inner cover 20. When the inner cover 20 is installed on the outer cover 10 and the cover teeth 221 of the inner cover 20 are separated from the pot teeth, the support surface 23 and the stopper 51 are in a stop fit. When the inner cover 20 rotates below the outer cover 10 to engage the cover teeth 221 and the pot teeth together, the avoidance concave surface 24 and the stopper 51 are in an avoidance fit. At this time, the insertion block 32 is inserted into the first chute 31 and abuts against the lower wall surface of the first chute 31. In this way, the inner cover 20 is restricted between the stopper 51 and the lower wall surface, thereby restricting the tilting range of the inner cover 20. After the inner cover 20 is corrected to make the latch block 42 enter the second chute 41, the inner cover 20 is installed approximately horizontally below the outer cover 10. When the inner cover 20 rotates below the outer cover 10, due to the stop fit between the support surface 23 and the stopper 51, and the insertion block 32 is supported and guided by the first chute 31, and the latch block 42 is supported and guided by the second chute 41, the inner cover 20 can rotate in the horizontal plane, preventing tilting and shaking, and avoiding subsequent jamming of the cover teeth 221 and the pot teeth when they are engaged. When the cover teeth 221 and the pot teeth are engaged together, the avoidance concave surface 24 and the stopper 51 are in an avoidance fit. In this case, when there is an upward pressure inside the cooking appliance, the pressure inside the cooking appliance will push the inner cover 20 to float upward relative to the outer cover 10. The avoidance fit relationship between the avoidance concave surface 24 and the stopper 51 can prevent the stopper 51 from interfering with the inner cover 20, enabling the inner cover 20 to float smoothly. The stopper 51 is preferably a stop rib.

[0058] As Figure 2 and Figure 9 shown, 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 latch block 42. With the above structure, 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 latch block 42, the insertion block 32 has a floating space in the first chute 31, and the latch block 42 also has a floating space in the second chute 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 upward pressure requirement of the cooking appliance.

[0059] In this embodiment, an anti-fooling structure is provided between the outer cover 10 and the inner cover 20 to enable the insertion block 32 to be inserted into the first chute 31 and the latch block 42 to be inserted into the second chute 41. By providing the anti-fooling structure, it can be ensured that the insertion block 32 is inserted into the first chute 31 and the latch block 42 is inserted into the second chute 41, avoiding incorrect installation of the inner cover 20 on the outer cover 10, resulting in the inability to achieve the pressure-bearing function.

[0060] It should be noted that the anti-fooling structure includes various implementation manners:

[0061] (1) The size of the insertion block 32 is larger than that of the clamping block 42, that is, the circumferential size of the insertion block 32 is larger than that of the clamping block 42. The clamping block 42 can extend into the second sliding groove 41 through the notch 43. Since the size of the insertion block 32 is larger than that of the clamping block 42, the insertion block 32 cannot be inserted into the second sliding groove 41 through the notch 43, thus preventing the misinstallation of the inner cover 20.

[0062] (2) The thickness dimension of the insertion block 32 is larger than that of the second sliding groove 41. In this way, the insertion block 32 cannot be inserted into the second sliding groove 41, making the inner cover 20 unable to rotate, and thus playing a role in preventing mistakes and avoiding the reverse installation of the inner cover 20.

[0063] (3) The thickness dimension of the clamping block 42 is larger than that of the first sliding groove 31. Furthermore, it can prevent the clamping block 42 from being inserted into the first sliding groove 31. By limiting with the thickness dimensions of the clamping block 42 and the first sliding groove 31, it can play a role in preventing the reverse installation of the inner cover 20 during installation.

[0064] (4) Other anti-mistake structures are provided on the first sliding groove 31, the second sliding groove 41 or the notch 43, such as limiting bosses or limiting grooves. Corresponding limiting grooves or limiting bosses are provided on the clamping block 42 and the insertion block 32 for matching installation, thus playing a role in preventing mistakes.

[0065] In this embodiment, in the circumferential direction of the cover assembly, the size of the clamping block 42 is smaller than that of the notch 43 and the size of the notch 43 is smaller than that of the insertion block 32 to form an anti-mistake structure. With the above structure, making the size of the clamping block 42 smaller than that of the notch 43 is convenient for distinguishing the insertion block 32 and the clamping block 42. Furthermore, it can enable the clamping block 42 to extend into the notch 43 and then rotate in the second sliding groove 41. And because the size of the notch 43 is smaller than that of the insertion block 32, it can prevent the insertion block 32 from being inserted into the notch 43, thus playing a role in preventing the reverse installation of the inner cover 20. Therefore, by limiting the circumferential dimensions of the insertion block 32, the clamping block 42 and the notch 43, 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, it can play a role in preventing mistakes for the inner cover 20.

[0066] In this embodiment, in the up-down direction of the cover assembly, the size of the insertion block 32 is larger than that of the second sliding groove 41 to form an anti-mistake structure. With the above structure, by making the size of the insertion block 32 larger than that of the second sliding groove 41, that is, the thickness dimension of the insertion block 32 is larger than that of the second sliding groove 41, it can avoid the direct insertion of the insertion block 32 into the second sliding groove 41, prevent the vertical misinstallation of the clamping block 42 and the insertion block 32, and thus ensure that the clamping block 42 is inserted into the second sliding groove 41 and the insertion block 32 is inserted into the first sliding groove 31, and correctly install the inner cover 20 on the outer cover 10.

[0067] Such as Figure 2As shown in the figure, in the up and down direction of the cover body assembly, the size of the first sliding groove 31 is larger than that of the insertion block 32, and the size of the second sliding groove 41 is larger than that of the clamping block 42. In this way, the size of the first sliding groove 31 is larger than that of the insertion block 32, and the size of the second sliding groove 41 is larger than that of the clamping block 42. The insertion block 32 has a floating space in the first sliding groove 31, and the clamping block 42 also has a floating space in the second sliding groove 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.

[0068] Another embodiment of the present utility model provides a cooking appliance, which includes a pot body and a cover body assembly. The cover body assembly is detachably covered on the pot body, and the cover body assembly is the cover body assembly provided above. Since the above cover body assembly can solve the problem that the pivot holes on the inner cover in the related art need to be aligned with the pivots for installation, making the assembly difficult, the cooking appliance including this cover body assembly can solve the same technical problem.

[0069] 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 control circuit board is arranged inside the housing, and electrical components such as pressure control and temperature measurement are arranged inside the outer cover. The combined type setting of the combined flip-type electric pressure cooker facilitates the wired connection between the electrical components inside the outer cover and the control circuit board inside the housing, ensuring the reliability of the electrical connection.

[0070] Of course, in other embodiments, the cooking appliance includes but is not limited to an electric pressure cooker and a multi-functional pot.
