Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a pot lid and a steaming appliance including the same. Background Technology

[0002] In existing steaming and cooking appliances, the stability of the heat-insulating cover assembly determines the sealing performance of the inner pot. The better the sealing performance, the better the pressure retention effect of the steaming and cooking appliance, and the shorter the steaming and cooking time. This not only enables fast cooking and saves energy, but also fully preserves the nutrients of the ingredients and improves the quality of cooking.

[0003] However, due to manufacturing errors in the components, there may be assembly gaps between the insulation cover assembly and the top cover assembly during the assembly process, resulting in insecure assembly. Consequently, the insulation cover assembly is prone to move relative to the top cover assembly, reducing the sealing performance of the inner pot. Summary of the Invention

[0004] Therefore, it is necessary to provide a pot lid and a cooking appliance including the pot lid that can reduce the assembly gap and improve the assembly firmness, in order to address the problem that there may be assembly gaps between the above-mentioned heat insulation cover assembly and the top cover assembly during the assembly process, which may lead to insecure assembly.

[0005] A pot lid, disposed on the pot body of a steaming or cooking appliance, the pot lid comprising:

[0006] A faceplate assembly includes a faceplate and at least one mating member mated to the faceplate, each of the mating members protruding from the inner end face of the faceplate along a first direction; and

[0007] The heat-insulating cover assembly is disposed on the inner side of the cover and includes a base and fittings disposed on the base and assembled one-to-one with the mating parts. Each fitting protrudes from the outer edge of the base along a second direction intersecting the first direction.

[0008] In this configuration, at least one of the corresponding mating parts and the assembly is retractable relative to the other along the second direction and is mated with the other.

[0009] In some embodiments, in at least one set of corresponding mating parts and assemblies, the assemblies are retractably mated with the mating parts.

[0010] In some embodiments, each of the retractable assemblies is defined as a movable assembly, and each of the mating parts that mate with each of the movable assemblies is defined as a movable mating part;

[0011] Each of the movable fittings has a snap-fit ​​end that protrudes from the inner end face of the cover along the first direction, and each of the movable fittings snaps into the snap-fit ​​end of its corresponding movable fitting.

[0012] In some embodiments, each of the movable mating members has a first position in which its engaging end abuts against a boss defining the overflow groove wall of the pot body, and a second position in which its engaging end extends into the overflow groove of the pot body.

[0013] The pot lid has an assembled state in which the heat-insulating cover plate assembly is assembled on the face cover assembly, and a missing state in which the heat-insulating cover plate assembly is disassembled from the face cover assembly.

[0014] When the pot lid is in the missing assembly state, each of the movable fitting parts is located in the first position. When the pot lid is in the assembled state, each of the movable fitting parts is located in the second position, and each of the movable fitting parts moves from the first position to the second position under the pressure of its corresponding movable fitting part.

[0015] In some embodiments, the faceplate assembly further includes at least one reset member corresponding to each of the movable mating members, each reset member abutting between its corresponding movable mating member and the faceplate, and each reset member being configured to provide a reset force for driving its corresponding movable mating member from the second position to the first position.

[0016] In some embodiments, each of the movable mating parts includes a reset end disposed opposite to its snap-fit ​​end, and a connecting segment connected between the reset end and the snap-fit ​​end. The connecting segment of each of the movable mating parts is rotatably connected to the cover, and each reset part abuts against the reset end of its corresponding movable mating part and the cover.

[0017] In some embodiments, the cover is further configured with at least one first stop portion corresponding to each of the movable mating members, each first stop portion being used to stop the corresponding movable mating member in the first position; and / or

[0018] The cover is also configured to have at least one second stop portion corresponding to each of the movable mating parts, each second stop portion being used to stop the corresponding movable mating part in the second position.

[0019] In some embodiments, each of the movable parts includes a movable portion and an elastic portion, the movable portion being slidably engaged with the base, and the movable portion extending outward and protruding beyond the outer edge of the base, the elastic portion abutting between the movable portion and the base;

[0020] In each of the movable fittings, the elastic portion is configured to contract during the engagement of the movable portion and the corresponding movable mating member at the snap-fit ​​end, in order to store elastic potential energy that can be used to drive the movable portion to elongate relative to the base.

[0021] In some embodiments, the base is configured with a guide cavity and a guide hole that are sequentially connected from the inside to the outside along the second direction; the movable part includes a first sub-part and a second sub-part that are sequentially connected from the inside to the outside along the second direction;

[0022] The first sub-part and the elastic part are both located in the guide cavity, the second sub-part passes through the guide hole, and in a third direction that intersects both the first direction and the second direction, the size of the first sub-part is larger than the size of the guide hole.

[0023] A steaming or cooking appliance, comprising:

[0024] The pot body; and

[0025] The pot lid as described in any of the above embodiments is disposed on the pot body.

[0026] The aforementioned pot lid and steaming appliance including it, having at least one of at least one set of corresponding mating parts and fittings that is retractable relative to the other in a second direction and engages with the other, can reduce the assembly gap between the fittings and mating parts by extending or retracting at least one of the mating parts and fittings. This makes the fit between the corresponding fittings and mating parts tighter and more secure, thereby reducing the possibility of the heat-insulating cover assembly moving (shaking and / or translating) relative to the cover. In this way, the heat-insulating cover assembly can better seal the opening of the inner pot. During the cooking process, the sealing performance of the inner pot is also better, and the possibility of gas in the inner pot escaping to the outside through the gap between the heat-insulating cover assembly and the inner pot is reduced. The pressure-holding effect of the steaming appliance is also better. Attached Figure Description

[0060] Please see Figure 1 This application provides a steaming appliance 1, which can be a rice cooker, a pressure cooker, or other steaming structure. The following embodiments all use a pressure cooker as an example for illustration.

[0061] The steaming appliance 1 includes a pot body 20 and a lid 10, with the lid 10 mounted on the pot body 20. The pot body 20 includes a main body 21 and an inner pot 22, both of which are hollow structures with an opening at one end. The main body 21 has a cavity for accommodating the inner pot 22, and the inner pot 22 has a steaming cavity for accommodating food. The lid 10 is used to open or close the opening of the inner pot 22. When the lid 10 is open, it facilitates the placement and removal of food; when the lid 10 is closed, it facilitates the steaming and cooking of food. Specifically, the lid 10 can be rotatably connected to the main body 21. Rotating the lid 10 relative to the main body 21 allows the opening or closing of the inner pot 22. Alternatively, the lid 10 can be detachably connected to the main body 21. When the lid 10 is detached, the opening of the inner pot 22 can be opened; when the lid 10 is mounted on the main body 21, the opening of the inner pot 22 can be closed. The following embodiments are all illustrated using the example of the pot lid 10 being detachably connected to the pot body 21.

[0062] Please also refer to Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 12 and Figure 13 The pot lid 10 includes a lid assembly 11 and a heat-insulating lid assembly 12. The lid assembly 11 includes a lid 111 and at least one mating member 112 fitted to the lid 111, with each mating member 112 protruding from the inner end face of the lid 111 along a first direction X. The heat-insulating lid assembly 12 is disposed inside the lid 111 and includes a base 121, a heat-insulating lid 123, a sealing ring 124, and at least one fitting 122. The heat-insulating lid 123, the sealing ring 124, and each fitting 122 are all disposed on the base 121, and all fittings 122 are assembled one-to-one with all mating members 112. Each fitting 122 protrudes from the outer edge of the base 121 along a second direction Y intersecting the first direction X. At least one of at least one set of corresponding mating members 112 and fittings 122 is retractable relative to the other along the second direction Y and is mated with the other. The heat-insulating cover plate 123 is used to close the opening of the inner pot 22, and the sealing ring 124 is used to seal the gap between the inner pot 22 and the heat-insulating cover plate 123.

[0063] The cover 111 is generally made of plastic, which has good insulation and heat insulation properties, reducing the risk of electrical conductivity and overheating. The inner end face of the cover 111 refers to the end face of the cover 111 facing the inner pot 22, and the inner side of the cover 111 refers to the side of the cover 111 facing the inner pot 22.

[0064] The seat 121 and sealing ring 124 are generally ring-shaped structures, while the insulation cover 123 is generally circular. The sealing ring 124 is fitted around the insulation cover 123, and the seat 121 is fitted around the sealing ring 124. The seat 121 and sealing ring 124 can be fixed together by screws, pins, or other mounting parts 125. The first direction X is parallel or approximately parallel to the central axis of the seat 121, and the second direction Y is the radial direction of the seat 121.

[0065] The number of mating parts 112 is equal to the number of assembly parts 122 and corresponds one-to-one. Each assembly part 122 mates with its corresponding mating part 112 to achieve the assembly between the cover assembly 11 and the insulation cover assembly 12. Each assembly part 122 and each mating part 112 can be one or more. Taking the example where there are multiple assembly parts 122 and mating parts 112, each assembly part 122 and its corresponding mating part 112 are defined as a group of assembly structures, and all groups of assembly structures extend circumferentially along the base 121. At least one of the corresponding mating parts 112 and assemblies 122 in at least one set can be retractable relative to the other along the second direction Y and mate with the other, meaning that: at least one of the mating parts 112 and assemblies 122 in each set of assembly structures can be retractable and mate with the other; or at least one of the mating parts 112 and assemblies 122 in some sets of assembly structures can be retractable and mate with the other; while the mating parts 112 and assemblies 122 in the remaining sets of assembly structures are detachably fixed. In any set of assembly structures, at least one of the mating parts 112 and assemblies 122 can be retractable relative to the other along the second direction Y and mate with the other, meaning that: for example, mating part 112 can be retractable relative to assemblies 122 and mate with assemblies 122; or, assemblies 122 can be retractable relative to mating part 112 and mate with mating part 112; or, both assemblies 122 and mating parts 112 can be retractable and mate with each other.

[0066] Alternatively, the stretchable design can be achieved by the component itself being made of an elastic material such as rubber or silicone, and during assembly, the component deforms due to compression or the presence of assembly gaps, thus forming a stretchable structure. Alternatively, the stretchable design can also be achieved by a drive component within the component driving the stretching and contraction of the remaining parts of the component.

[0067] Optionally, in each assembly structure, the assembly part 122 and the mating part 112 can be connected by means of fitting, fastening, pressing, etc.

[0068] In the prior art, the mating parts 112 and the fitting parts 122 in each assembly structure are detachably fixed. Due to manufacturing errors in the parts, there may be assembly gaps during the assembly of the mating parts 112 and the fitting parts 122 in each assembly structure. This can lead to insecure assembly of the fitting parts 122 and the mating parts 112 within the same group. Consequently, the heat preservation cover assembly 12 is prone to move relative to the cover assembly 11, reducing the sealing performance of the inner pot 22 and ultimately resulting in poor pressure retention of the cooking appliance 1.

[0069] In this application, since at least one of the corresponding mating parts 112 and the fittings 122 is retractable relative to the other along the second direction Y and engages with the other, the assembly gap between the fittings 122 and the mating parts 112 can be reduced by the retraction of the mating parts 112 and the fittings 122, so that the fit between the corresponding fittings 122 and the mating parts 112 is tighter and more secure. As a result, the possibility of the heat insulation cover assembly 12 moving (shaking and / or translating) relative to the cover 111 is reduced. In this way, the heat insulation cover assembly 12 can better seal the opening of the inner pot 22. During the cooking process, the sealing performance of the inner pot 22 is better, the possibility of gas in the inner pot 22 escaping to the outside through the gap between the heat insulation cover assembly 12 and the inner pot 22 is reduced, and the pressure holding effect of the cooking appliance 1 is better.

[0070] To further reduce the assembly gap between the fitting 122 and the mating part 112, and to improve the assembly firmness between the insulation cover assembly 12 and the face cover assembly 11, preferably, the fitting 122 and the mating part 112 in each assembly structure are retractably connected.

[0071] In some embodiments of this application, in at least one set of corresponding mating parts 112 and mounting parts 122, the mounting parts 122 are retractably mated with the mating parts 112.

[0072] In other words, during the assembly process, the mating part 112 is fixed, and only the assembly part 122 extends and retracts relative to the corresponding mating part 112 to reduce the assembly gap between the two.

[0073] Since all mating parts 112 are fixed, the assembly parts 122 corresponding to each mating part 112 can be easily positioned during the assembly process, which helps to achieve rapid assembly.

[0074] In some embodiments of this application, each retractable fitting 122 is defined as a movable fitting 122a, and each mating part 112 that mates with each movable fitting 122a is defined as a movable mating part 112a; each movable mating part 112a has a fastening end 1121 that protrudes from the inner end face of the cover 111 along a first direction X, and each movable fitting 122a and its corresponding movable mating part 112a fasten together.

[0075] Specifically, each movable component 122a is telescopic relative to its corresponding movable mating component 112a, which reduces the assembly gap between each movable component 122a and its corresponding movable mating component 112a in the second direction Y, thereby reducing the risk of movement of the insulation cover assembly 12 relative to the cover 111 in the second direction Y. The engaging ends 1121 of each movable component 122a and its corresponding movable mating component 112a further enhance the assembly firmness between them, reducing the risk of movement of the insulation cover assembly 12 relative to the cover 111 in the first direction X. Therefore, the entire insulation cover assembly 12 and the cover assembly 11 have superior installation reliability, which helps to improve the sealing performance of the inner pot 22.

[0076] Please also refer to Figure 10 To further improve the reliability of assembly, in some embodiments of this application, the non-retractable assembly 122 is defined as a fixed assembly 122b, and the non-retractable mating part 112 is defined as a fixed mating part 112b. When there is a fixed assembly 122b in all the assemblies 122 and a fixed assembly 122b in all the mating parts 112, each fixed mating part 112b also has a fastening end 1121 that protrudes from the inner end face of the cover 111 along the first direction X, and each fixed assembly 122b and its corresponding fixed mating part 112b fasten together.

[0077] Please also refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments of this application, each movable mating part 112a has a first position in which its snap-fit ​​end 1121 abuts against the boss 212 that defines the overflow groove 211 wall of the pot body 20, and a second position in which its snap-fit ​​end 1121 extends into the overflow groove 211 of the pot body 20; the pot lid 10 has an assembled state in which the heat-insulating cover plate assembly 12 is assembled on the face cover assembly 11 and a missing state in which the heat-insulating cover plate assembly 12 and the face cover assembly 11 are disassembled; when the pot lid 10 is in the missing state, each movable mating part 112a is located in the first position; when the pot lid 10 is in the assembled state, each movable mating part 112a is located in the second position, and each movable mating part 112a moves from the first position to the second position under the pressure of its corresponding movable fitting 122a.

[0078] Specifically, the pot body 20 is also provided with a locking part 213, each movable mating part 112a is also provided with a fastening part 1124, the opening of the inner pot 22 is provided with a pot tooth 221, and the inner side of the cover 111 is provided with a steel tooth 1113.

[0079] When the lid 10 is in the missing state, each movable mating part 112a is in the first position where its locking end 1121 abuts against the boss 212 that defines the overflow groove 211 wall of the pot body 20. In this state, the top cover 111 and the heat preservation cover assembly 12 are both supported by the locking ends 1121 of all the movable mating parts 112a. At this time, the locking part 213 and the locking part 1124 cannot contact and lock together, and the steel teeth 1113 on the top cover 111 and the pot teeth 221 on the inner pot 22 are at the same horizontal height. After the lid 10 is rotated relative to the pot body 20 by a certain angle, the steel teeth 1113 on the top cover 111 collide with the pot teeth 221 on the inner pot 22, causing the steel teeth 1113 on the top cover 111 and the pot teeth 221 on the inner pot 22 to fail to lock together. In this way, the heat preservation cover assembly 12 cannot seal the opening of the inner pot 22, so as to remind the user that the heat preservation cover assembly 12 needs to be installed.

[0080] When the lid 10 is in the assembled state, each movable mating part 112a is in the second position where its snap-fit ​​end 1121 extends into the overflow groove 211 of the pot body 20. In this state, Figure 1Taking the steaming appliance 1 placed on a horizontal surface with the first direction X pointing vertically downwards as an example, the engaging part 213 is located above the fastening part 1124 and engages with it. Simultaneously, the steel teeth 1113 on the lid 111 are located below the pot teeth 221 on the inner pot 22 and lock in place. At this time, the heat-insulating cover assembly 12 can seal the opening of the inner pot 22. Furthermore, due to the engagement of the engaging part 213 and the fastening part 1124, as well as the engagement between the steel teeth 1113 and the pot teeth 221, the risk of the lid 10 wobbling relative to the pot body 20 in the vertical direction can be reduced, ensuring the lid 10 is stably mounted on the pot body 20. Therefore, this design prevents the heat-insulating cover assembly 12 from being misinstalled, thus improving the reliability of the steaming appliance 1.

[0081] It is worth mentioning that in the embodiment with fixed fitting 112b and fixed assembly 122b, regardless of whether the pot lid 10 is in an assembled state or a missing state, the snap-fit ​​end 1121 of each fixed fitting 112b extends into the overflow groove 211 of the pot body 20, and does not hinder the closing between the pot lid 10 and the pot body 20.

[0082] Please refer to it again. Figure 1 In some embodiments of this application, the faceplate assembly 11 further includes at least one reset member 113 corresponding to each of the movable mating members 112a. Each reset member 113 abuts between its corresponding movable mating member 112a and the faceplate 111. Each reset member 113 is configured to provide a reset force for driving its corresponding movable mating member 112a from a second position to a first position.

[0083] Among them, the reset component 113 can be a compression spring, or an elastic structure such as silicone with good elasticity.

[0084] In other words, after the heat insulation cover assembly 12 is removed from the cover assembly 11, since each movable mating part 112a lacks the function of its corresponding movable mounting part 122a, each movable mating part 112a can automatically move to the first position under the action of the reset part 113 that abuts against it. In this way, the pot lid 10 can switch to the missing installation state to remind the user that the heat insulation cover assembly 12 has not been installed.

[0085] Please see Figure 11 In some embodiments of this application, each movable mating part 112a is recessed on the surface of its corresponding reset part 113 to form a first limiting groove 1126. The bottom wall of each first limiting groove 1126 protrudes to form a first positioning rib 1127, and the first positioning rib 1127 is spaced apart from the side wall of the first limiting groove 1126. Each reset part 113 is a compression spring, and one end of each reset part 113 extends into the corresponding first limiting groove 1126 and is sleeved on the outside of the corresponding first positioning rib 1127.

[0086] By setting the first limiting groove 1126 and the first positioning rib 1127, the stability of the reset member 113 during installation is improved. Furthermore, since the first positioning rib 1127 can expand the reset member 113, and the first positioning rib 1127 and the first limiting groove 1126 work together to guide the compression of the reset member 113, each reset member 113 can stably drive its corresponding movable mating part 112a to switch positions.

[0087] In some embodiments of this application, each movable mating part 112a includes a reset end 1122 disposed opposite to its fastening end 1121, and a connecting segment 1123 connected between the reset end 1122 and the fastening end 1121. The connecting segment 1123 of each movable mating part 112a is rotatably connected to the cover 111, and each reset part 113 abuts between the reset end 1122 of its corresponding movable mating part 112a and the cover 111.

[0088] Specifically, in this embodiment, the first limiting groove 1126 and the first positioning rib 1127 are both formed on the reset end 1122.

[0089] Among them, the connecting section 1123 of each movable mating part 112a has a rotating shaft 1125 on its opposite sides, and the cover 111 has a rotating hole corresponding to each rotating shaft 1125. Each rotating shaft 1125 passes through the corresponding rotating hole, which can realize the rotational connection between each movable mating part 112a and the cover 111.

[0090] During the actual assembly process, the snap-fit ​​ends 1121 of each movable mating part 112a rotate in the forward direction relative to the cover 111 under the action of their respective movable fitting parts 122a, so as to switch from the first position to the second position. At this point, the heat preservation cover plate assembly 12 is assembled and the pot lid 10 can be closed on the pot body 20. During the disassembly of the heat preservation cover plate 123, the force exerted by each movable fitting part 122a on each movable mating part 112a on the heat preservation cover plate assembly 12 gradually decreases until it disappears. Then, each movable mating part 112a can rotate in the opposite direction and return to the first position under the action of its respective reset part 113.

[0091] The method of switching the position of each moving mating part 112a by rotation requires less space and is more compact than translation, thus helping to improve the miniaturization of the cover 111.

[0092] Please see Figure 3In some embodiments of this application, the cover 111 is further configured with at least one first stop portion 1111 corresponding to each movable mating member 112a, each first stop portion 1111 being used to stop the movable mating member 112a corresponding to it in a first position; and / or the cover 111 is further configured with at least one second stop portion 1112 corresponding to each movable mating member 112a, each second stop portion 1112 being used to stop the movable mating member 112a corresponding to it in a second position.

[0093] The movable mating part 112a preferably has a first stop portion 1111 and a second stop portion 1112 formed on the cover 111. Each first stop portion 1111 and each second stop portion 1112 can be L-shaped, V-shaped, or other shapes. Here, the specific shape of each first stop portion 1111 and each second stop portion 1112 is not limited, only that each first stop portion 1111 and each second stop portion 1112 can limit the rotation of the corresponding movable mating part 112a.

[0094] When each movable mating part 112a abuts against its corresponding first stop part 1111, each movable mating part 112a rotates to the first position and stops moving. When each movable mating part 112a abuts against its corresponding second stop part 1112, each movable mating part 112a rotates to the second position and stops moving.

[0095] By setting the first stop 1111 and / or the second stop 1112, the rotation angle of each movable mating part 112a can be limited, thereby reducing the risk that the rotation angle of each movable mating part 112a is too large and hinders the normal operation of the cooking appliance 1. For example, during the process of each movable mating part 112a rotating from the first position to the second position, if the rotation angle of each movable mating part 112a is too large, it may rotate out of the overflow groove 211 corresponding to it, resulting in the lid 10 not being able to close. As another example, during the process of each movable mating part 112a rotating from the second position to the first position, if the rotation angle of each movable mating part 112a is too large, it may rotate to a position where it does not abut against the boss 212. In this case, the lid 10 may close, resulting in the inability to notify the user that the heat preservation cover assembly 12 is not installed.

[0096] Please refer to it again. Figure 9 , Figure 12 and Figure 13In some embodiments of this application, each movable assembly 122a includes a movable portion 1221 and an elastic portion 1222. The movable portion 1221 is slidably coupled to the seat 121 and extends outward and protrudes from the outer edge of the seat 121. The elastic portion 1222 abuts between the movable portion 1221 and the seat 121. In each movable assembly 122a, the elastic portion 1222 is configured to contract during the process of the movable portion 1221 and the corresponding movable mating member 112a pressing and engaging, so as to store elastic potential energy that can be used to drive the movable portion 1221 to extend relative to the seat 121.

[0097] Among them, the elastic part 1222 can be a compression spring, or an elastic part 1222 made of silicone or other materials with superior elasticity.

[0098] Under the action of the elastic part 1222, the movable part 1221 connected to the elastic part 1222 can automatically extend and retract, so that each movable assembly 122a can automatically adjust according to the assembly gap between itself and the corresponding movable mating part 112a, and has better adjustment flexibility.

[0099] Please refer to it again. Figure 9 And see also Figure 14 In some embodiments of this application, the seat 121 is configured with a guide cavity 1211 and a guide hole that are sequentially connected from the inside to the outside along the second direction Y; the movable part 1221 includes a first sub-part 12211 and a second sub-part 12212 that are sequentially connected from the inside to the outside along the second direction Y; the first sub-part 12211 and the elastic part 1222 are both located in the guide cavity 1211, the second sub-part 12212 passes through the guide hole, and on the third direction Z that intersects both the first direction X and the second direction Y, the size of the first sub-part 12211 is larger than the size of the guide hole.

[0100] The number of guide cavities 1211 and guide holes is equal to the number of movable mating parts 112a and corresponds one-to-one. The first sub-part 12211 of the movable part 1221 of each movable mating part 112a is located in the corresponding guide cavity 1211, and the second sub-part 12212 of the movable part 1221 of each movable mating part 112a passes through the corresponding guide hole.

[0101] The guide cavity 1211 can guide the sliding of the first sub-part 12211, and the guide hole can guide the sliding of the second sub-part 12212, so as to improve the stability of the sliding of the movable assembly 122a.

[0102] Furthermore, in the third direction Z, the size of the guide cavity 1211 is larger than the size of the guide hole, and the size of the first sub-part 12211 is larger than the size of the second sub-part 12212 and the guide hole. This prevents the first sub-part 12211 from sliding out of the guide cavity 1211, thereby giving the movable assembly 122a better telescopic stability.

[0103] Please also refer to Figure 15 and Figure 16 In some embodiments of this application, the movable part 1221 of each movable assembly 122a is recessed on the surface of the elastic part 1222 that abuts against it to form a second limiting groove 12213. The bottom wall of each second limiting groove 12213 protrudes to form a second positioning rib 12214, and the second positioning rib 12214 is spaced apart from the side wall of the second limiting groove 12213. Each elastic part 1222 is a compression spring, and one end of each elastic part 1222 extends into the corresponding second limiting groove 12213 and is sleeved on the outside of the corresponding second positioning rib 12214.

[0104] By setting the second limiting groove 12213 and the second positioning rib 12214, the stability of the elastic part 1222 during installation is improved. Furthermore, since the second positioning rib 12214 can expand the elastic part 1222, and the combined action of the second positioning rib 12214 and the second limiting groove 12213 can guide the compression of the elastic part 1222, the elastic part 1222 of each movable component 122a can stably drive the extension and retraction of its corresponding movable part 1221. In some embodiments of this application, there is only one movable component 122a and one fixed component 122b, which protrude from opposite sides of the base 121 and respectively mate with the corresponding movable mating part 112a and fixed mating part 112b. During assembly, the fixed component 122b is first mated with the fixed mating part 112b, and then the movable component 122a is mated with the fixed component 122b. In this configuration, since the fixed fitting 122b and the fixed mating part 112b are mated, the position of the insulation cover assembly 12 can be roughly fixed in advance to facilitate the subsequent mating of the movable mating part 112a and the movable fitting 122a.

[0105] In some embodiments of this application, the fixing member 112b and the cover 111 are formed as a single piece, and the fixing member 112b has a locking groove 1128. One end of the fixing accessory 122b extending out of the base 121 engages with the locking groove 1128. This arrangement improves the ease of assembly between the fixing member 112b and the fixing accessory 122b.

[0106] Please also refer to Figure 9 , Figure 14 , Figure 17 and Figure 18 In one embodiment, the base 121 includes a first portion 1213 and a second portion 1214. The second portions 1214 are detachably stacked along a first direction X, and the first portions 1213 and the second portions 1214 surround and form guide cavities 1211 and guide holes. Specifically, the first portion 1213 is configured with a plurality of interconnected first guide grooves 12131 and second guide grooves 12132. The second portion 1214 is configured with a cover 12141 covering the openings of the first guide grooves 12131 and second guide grooves 12132. The cover 12141 and the groove wall of the first guide groove 12131 define a guide cavity 1211, and the cover 12141 and the groove wall of the second guide groove 12132 define a guide hole.

[0107] The first part 1213 and the second part 1214 are detachably connected, and when the first part 1213 and the second part 1214 are detached, each movable component 122a can be easily installed and removed. When the first part 1213 and the second part 1214 are connected, each movable component 122a can be confined within its corresponding guide cavity 1211 and guide hole.

[0108] Please also refer to Figure 21 , Figure 22 and Figure 23 In some embodiments of this application, the inner surface of the sealing ring 124 is recessed outward along the second direction Y, forming an annular groove 1241 that is recessed relative to the inner surface of the sealing ring 124, and a mounting protrusion 1242 that protrudes relative to the outer surface of the sealing ring 124. The heat insulation cover 123 is located within the hollow area defined by the sealing ring 124, and the outer edge of the heat insulation cover 123 extends into the annular groove 1241 to achieve fixation between the heat insulation cover 123 and the sealing ring 124. In some embodiments of this application, the outer edge of the heat insulation cover 123 extends inward along the second direction Y to form a flange 1231. The flange 1231 reduces the risk of burrs, sharp edges, and other processing defects that may injure users during processing.

[0109] Please refer to the diagram as well. Figure 24 and Figure 25 In some embodiments of this application, a positioning through hole 1243 is provided on the mounting protrusion 1242, and positioning posts 12142 are provided at positions opposite to the positioning through hole 1243 on the first part 1213 and the second part 1214. The first part 1213 and the second part 1214 are distributed on opposite sides of the mounting protrusion 1242 along the first direction X, and the positioning posts 12142 on the first part 1213 and the second part 1214 respectively pass through the positioning through hole 1243 on the mounting protrusion 1242.

[0110] The location and number of positioning through holes 1243 can be selected according to requirements and are not limited here. The positions of the positioning posts 12142 on the first part 1213 and the second part 1214 are adjusted according to the location of the positioning through holes 1243.

[0111] By setting the positioning post 12142 and the positioning through hole 1243, the positioning between the first part 1213, the second part 1214 and the sealing ring 124 can be realized, so that the first part 1213, the second part 1214 and the sealing ring 124 can be accurately fixed in the future.

[0112] In some embodiments of this application, the first part 1213 has a plurality of first mounting holes 12143 spaced apart along its circumference, the second part 1214 has a plurality of second mounting holes 12144 spaced apart along its circumference, and the mounting protrusion 1242 has a plurality of third mounting holes 1244 spaced apart along its circumference. The insulation cover assembly 12 also includes a plurality of mounting members 125, each corresponding one-to-one with a plurality of first mounting holes 12143, a plurality of second mounting holes 12144, and a plurality of third mounting holes 1244. Each mounting member 125 passes through a corresponding first mounting hole 12143, a second mounting hole 12144, and a third mounting hole 1244, and is used to fix the first part 1213, the second part 1214, and the sealing ring 124.

[0113] For example, mounting component 125 can be a screw, pin, or other fixing structure.

[0114] By providing the mounting component 125, the reliability of the assembly between the seat 121 and the sealing ring 124 can be improved.

[0115] Please also refer to Figure 19 and Figure 20 In some embodiments of this application, the outer edge of the insulation cover 123 is also provided with a plurality of clearance notches 1232, and the plurality of clearance notches 1232 correspond one-to-one with a plurality of mounting parts 125. Each mounting part 125 passes through the corresponding clearance notch 1232 to achieve clearance cooperation between the mounting part 125 and the clearance notch 1232.

[0116] By setting the clearance notch 1232, the resistance during the assembly process of the mounting part 125 can be reduced, thereby enabling the rapid assembly of the quick-mounting part 125.

[0117] The aforementioned pot lid 10 and the steaming appliance 1 including it have at least one of at least one set of corresponding mating parts 112 and fittings 122 that is retractable relative to the other along the second direction Y and engages with the other. By retracting the mating parts 112 and fittings 122, the assembly gap between fittings 122 and mating parts 112 can be reduced, so that the corresponding fittings 122 and mating parts 112 are more tightly and firmly engaged. As a result, the possibility of the heat-insulating cover assembly 12 moving (shaking and / or translating) relative to the cover 111 is reduced. In this way, the heat-insulating cover assembly 12 can better seal the opening of the inner pot 22. During the cooking process, the sealing performance of the inner pot 22 is also better, and the possibility of gas in the inner pot 22 escaping to the outside through the gap between the heat-insulating cover assembly 12 and the inner pot 22 is reduced. The pressure-holding effect of the steaming appliance 1 is also better.

[0118] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0119] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
