Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a pot lid assembly and a cooking utensil. Background Technology

[0002] Cooking utensil lids generally consist of a top cover and an inner liner. The inner liner houses various functional components, while the top cover forms the top and sides of the lid. The top cover and inner liner are connected and secured with snap-fit ​​fasteners. At the rear of the lid, where it connects to the pot body, the stress is greater. To prevent deformation or separation of the top cover and inner liner, an additional securing structure is provided at this rear to improve the stability of the lid and liner.

[0003] The fixing structure includes a male buckle and a limiting rib on the top cover, and a female buckle and a limiting groove on the inner liner. The limiting rib and the limiting groove work together to restrict the left and right displacement of the inner liner and the top cover. The limiting rib is exposed on the outer surface of the pot lid, while the male buckle and the female buckle are hidden between the inner liner and the top cover, thus fixing the two together.

[0004] When the inner liner and the lid move relative to each other in the left and right directions, the compressive force generated between them is directly borne by the limiting rib. However, the limiting rib is a thin-walled rib with low structural strength, so it is prone to breakage when subjected to compression. Furthermore, the limiting rib is exposed on the outer surface of the lid, so breakage will cause product quality problems.

[0005] Furthermore, in order to ensure that the limiting ribs and limiting grooves can fit together, a certain design gap needs to be reserved between the limiting ribs and limiting grooves. However, the existence of this gap means that during the assembly process, assembly errors can cause the gap between the limiting ribs and limiting grooves on one side to be too small, while the gap between the limiting ribs and limiting grooves on the other side to be too large. This results in a positional deviation between the cover and the inner liner in the left and right directions. This not only affects the appearance quality of the product, but also further increases the compressive force between the limiting ribs and limiting grooves on the side with the smaller gap, exacerbating the risk of breakage of the limiting ribs on that side. Utility Model Content

[0006] This utility model provides a pot lid assembly and cooking appliance to solve the problem that when the lid and inner liner move in the left and right directions, a large compressive force is generated between the limiting rib and the limiting groove, which causes the limiting rib to break easily and affects product quality.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A pot lid assembly includes a top cover and a liner located below the top cover. The top cover has a notch at its rear end, and the liner has connecting arms at its rear end that engage with the edges of the notch. The top cover has limiting ribs and snap-fit ​​portions on both sides of the notch, with the snap-fit ​​portions located on the side of the limiting ribs facing away from the notch. The liner has limiting grooves and mating portions on the connecting arms, with the limiting grooves located on opposite sides of the two connecting arms. The limiting ribs and limiting grooves engage with each other laterally, and the snap-fit ​​portions and mating portions engage with each other vertically. The snap-fit ​​portion also has an abutment portion on the side near the limiting ribs, and the gap between the abutment portion and the mating portion is smaller than the lateral gap between the limiting ribs and the limiting grooves.

[0009] In this invention, the connecting arm at the rear end of the liner is used to connect with the pot body. The connecting arm is located on both sides of the notch on the top cover, so that the notch and the connecting arm cooperate to form a connecting groove for cooperation with the connecting structure on the pot body. The snap-fit ​​part and the mating part engage to fix the top cover and the liner at the rear end, and also to provide a vertical stop to restrict their relative vertical movement. The limiting groove and the limiting rib cooperate to provide a lateral stop to restrict their relative lateral (left-right) movement. The limiting groove is located on the side where the two connecting arms face each other, so after the limiting rib extends into the limiting groove, the limiting rib is located inside the connecting groove and on the outer surface of the pot cover assembly.

[0010] In this invention, an abutment is provided on the side of the snap-fit ​​part near the limiting rib. The abutment can laterally stop the mating part to restrict the lateral (left-right) relative movement of the cover and the liner. The reserved gap between the abutment and the mating part is smaller than the reserved gap between the limiting rib and the limiting groove. This allows the abutment and the mating part to preferentially abut when the cover and the liner tend to move laterally after assembly. At this time, the limiting rib and the limiting groove have a larger reserved gap and therefore have not yet formed abutment, or the abutment force is small. This ensures that the compressive force in the left-right direction is preferentially borne by the abutment and the mating part. On the one hand, the structural strength of the abutment is higher than that of the limiting rib, making it less prone to damage. On the other hand, the abutment is located inside the limiting rib, and after the cover and the liner are assembled, the abutment is covered, so even if damage occurs, it will not affect the appearance quality of the lid assembly. At the same time, this solution also greatly reduces the stress on the limiting ribs, reducing the probability of the limiting ribs breaking due to excessive stress during production and transportation, and ensuring the appearance quality of the product.

[0011] The abutting part is provided with a guide slope, and the mating part is provided with a mating slope that mates with the guide slope on the side facing the limiting groove. The gap between the guide slope and the mating slope is smaller than the transverse gap between the limiting rib and the limiting groove.

[0012] In this design, when the cover and liner tend to move laterally relative to each other, the abutting part and the mating part abut against each other via an inclined surface. On the one hand, this allows the abutting force between the two to be dispersed along the inclined surface, reducing localized stress and preventing stress concentration and damage to the abutting part. On the other hand, during the assembly of the cover and liner, the guide inclined surface guides the mating part, allowing it to slide along the guide inclined surface to a position centered on the left and right sides of the cover and liner. This makes the gaps between the limiting ribs and limiting grooves on both sides closer together, which not only improves the overall appearance quality of the lid assembly but also makes the force on the limiting ribs on both sides more even, preventing excessive force on one side of the limiting ribs and damage.

[0013] One end of the abutting part is fixed to the snap-fit ​​part, and the thickness of the abutting part gradually increases in the direction close to the snap-fit ​​part so as to form a guide slope on the surface of the abutting part.

[0014] In this design, the thickness of the abutment gradually increases towards the snap-fit ​​part. This not only increases the structural strength of the abutment in that direction, but also disperses the abutment force on the guide slope when the mating part comes into contact with the abutment, alleviating localized stress on the abutment and reducing the risk of breakage. Simultaneously, the connection between the abutment and snap-fit ​​parts is the area with the greatest thickness, effectively improving the structural strength at this location and the overall structural strength of the snap-fit ​​part. This results in a more stable fit between the snap-fit ​​and the mating part, ensuring the stability of the connection between the cover and the rear end of the liner, and reducing the possibility of damage to the snap-fit ​​part.

[0015] The abutting part is fixedly connected to the snap-fit ​​part and the limiting rib.

[0016] In this design, the abutment portion connects the locking portion and the limiting rib into one unit. This not only acts as a reinforcing rib, increasing the structural strength of both the locking portion and the limiting rib and reducing the possibility of damage under stress, but also, when the limiting rib is under stress, the abutment portion can transfer part of the force to the locking portion. This allows the locking portion and the abutment portion to share the force on the limiting rib, thus reducing the stress on the limiting rib. Conversely, the limiting rib and the abutment portion can also share the force on the locking portion. This results in a more dispersed distribution of force when a single structure is under stress, avoiding stress concentration.

[0017] The edges on both sides of the notch fold inward toward the inside of the cover to form a flange. The flange forms a limiting rib, and a blocking space is formed between the limiting rib and the inner surface of the cover. The snap-fit ​​part is located within the blocking space.

[0018] In this design, the edges on both sides of the notch fold inward to form flanges, which act as limiting ribs. This improves the uniformity of the lid's appearance and makes the folds smoother and more rounded, avoiding sharp corners on the lid assembly's surface. Furthermore, the flange design allows the notch's edge to fit more snugly with the connecting arm, preventing the notch's edge from lifting relative to the connecting arm. Because the flange folds inward to the lid, it creates a concealed space with the inner surface of the lid. The locking part is located within this concealed space. When the limiting ribs and limiting grooves engage, the liner and the connecting arm on the liner, together with the lid, seal the concealed space, allowing the locking and mating parts to engage internally without being exposed on the outer surface. This achieves a concealed design and improves the appearance quality of the lid assembly.

[0019] The width of the limiting rib gradually increases from top to bottom, so that the surface of the limiting rib facing the inside of the cover forms a first positioning slope, and the limiting groove has a second positioning slope that matches the first positioning slope.

[0020] In this design, the width of the limiting rib gradually increases downwards; that is, the width of the limiting rib is larger closer to the lower edge of the cover. Since the lower edge of the notch is prone to deformation, increasing the width of the limiting rib improves the limiting effect after the limiting rib and the limiting groove are engaged, thereby reducing the deformation of the lower end of the cover and making the lower end of the cover and the liner fit more closely. Simultaneously, during assembly, the first and second positioning bevels can guide the installation of the cover and the liner, allowing the snap-fit ​​and mating parts to naturally engage.

[0021] The snap-fit ​​part is a horizontally extending snap-fit ​​rib, and a vertically extending reinforcing rib is provided on the side of the snap-fit ​​rib near the limiting rib. The reinforcing rib forms the abutment part, and the mating part is a mating buckle provided at the rear edge of the connecting arm.

[0022] In this design, the reinforcing rib extends vertically, while the snap-fit ​​rib extends horizontally, with both extending perpendicularly. This arrangement not only ensures that the combined structure provides both a horizontal and vertical stop with the mating part, but also enhances the overall structural strength of the snap-fit ​​rib and reinforcing rib, thus strengthening the structure. The mating clip is located at the rear edge of the connecting arm, allowing the snap-fit ​​rib and the mating clip to engage horizontally. After mating, this provides a stop in both the vertical and horizontal directions, restricting the relative vertical movement of the cover and the liner.

[0023] A limiting part is also provided on the side of the snap-fit ​​part away from the limiting rib, and a limiting space for accommodating the mating part is formed between the abutting part and the limiting part.

[0024] In this design, the limiting part and the abutting part are located on the left and right sides of the locking part, thus forming a limiting space for accommodating the mating part. When the locking part and the mating part are engaged, both sides of the mating part are stopped and thus confined within the limiting space. This limits the relative displacement of the cover and the liner in the left and right directions, improves the relative positional stability, and prevents the cover and the liner from shifting over a large range.

[0025] The cover includes a panel located above the liner and a skirt surrounding the outer periphery of the liner. The skirt is provided with a first fixing buckle. There are multiple first fixing buckles that are spaced apart along the circumference of the liner. The outer edge of the liner is provided with a second fixing buckle that cooperates with the first fixing buckle.

[0026] In this design, the cover's skirt edge is circumferentially fitted with multiple first fixing clips, which cooperate with second fixing clips on the liner edge to achieve multi-point circumferential fixation of the cover and liner. This results in a more even distribution of fixing force, improving connection stability and preventing the liner from tilting relative to the cover. Simultaneously, at the rear ends, snap-fit ​​and mating parts specifically enhance the connection strength in this area, improving the overall connection effect of the cover and liner, preventing weak areas, and improving product quality.

[0027] This utility model also discloses a cooking appliance, including a pot body and the aforementioned pot lid assembly. The pot body is provided with a connecting seat, which is located between connecting arms and rotatably connected to the connecting arms so that the pot lid assembly can rotate relative to the pot body to open or close the pot body.

[0028] The notch and the connecting part together form a connecting groove. The connecting seat of the pot body extends into the connecting groove and rotates to connect with the connecting arms on both sides, making the position of the lid and the pot body more compact and reducing the gap between the lid assembly and the pot body on the appearance of the cooking utensil.

[0044] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0049] like Figures 1 to 3 As shown, a pot lid assembly includes a top cover 1 and a liner 2 located below the top cover 1. The rear end of the top cover 1 is provided with a notch 15, and the rear end of the liner 2 is provided with connecting arms 23 that engage with the two sides of the notch 15. The top cover 1 is provided with limiting ribs 14 and snap-fit ​​portions 12 on both sides of the notch 15. The snap-fit ​​portions 12 are located on the side of the limiting ribs 14 away from the notch 15. The liner 2 is provided with limiting grooves 22 and mating portions 21 on the connecting arms 23. The limiting grooves 22 are located on the opposite sides of the two connecting arms 23. The limiting ribs 14 and the limiting grooves 22 engage laterally, and the snap-fit ​​portions 12 and the mating portions 21 engage vertically. The snap-fit ​​portion 12 is also provided with an abutment portion 13 on the side near the limiting ribs 14. The gap L1 between the abutment portion 13 and the mating portion 21 is smaller than the lateral gap L2 between the limiting ribs 14 and the limiting grooves 22.

[0050] It is understandable that, such as Figure 1 , Figure 2 As shown, the rear end of the pot lid assembly is also the rear end of the top cover 1 and the liner 2, which is the end away from the user when in use. Specifically, the connecting arm 23 at the rear end of the liner 2 is used to rotate and connect with the pot body, so that the front end of the pot lid assembly can rotate up and down around the connection point at the rear end to open and close the lid.

[0051] In this invention, the connecting arm 23 is located on both sides of the notch 15 on the cover 1, so that the notch 15 and the connecting arm 23 cooperate to form a connecting groove 11 for cooperation with the connecting structure on the pot body. The snap-fit ​​part 12 and the mating part 21 engage to fix the cover 1 and the liner 2 at the rear end, and also provide a vertical stop to limit their relative vertical movement. The limiting groove 22 and the limiting rib 14 provide a lateral stop to limit their relative lateral (left-right) movement. The limiting groove 22 is located on the side of the two connecting arms 23 facing each other (the side facing the connecting groove 11). Therefore, after the limiting rib 14 extends into the limiting groove 22, the limiting rib 14 is located in the connecting groove 11 and is on the outer surface of the pot cover assembly.

[0052] In this utility model, the snap-fit ​​part 12 is also provided with an abutment part 13 on the side near the limiting rib 14. The abutment part 13 can stop laterally with the mating part 21 to limit the lateral (left-right) relative movement of the cover 1 and the liner 2. The reserved gap between the abutment part 13 and the mating part 21 is smaller than the reserved gap between the limiting rib 14 and the limiting groove 22. This means that after the cover 1 and the liner 2 are assembled, when the cover 1 and the liner 2 tend to move laterally relative to each other, the abutment part 13 and the mating part 21 will form an abutment first. At this time, the limiting rib 14 and the limiting groove 22 have a large reserved gap, so they have not yet formed an abutment or the abutment force is small. This design ensures that the lateral compressive forces are primarily borne by the abutment portion 13 and the mating portion 21. Firstly, the abutment portion 13 has higher structural strength than the limiting rib 14, making it less prone to damage. Secondly, the abutment portion 13 is located inside the limiting rib 14, and after the cover 1 and the liner 2 are assembled, the abutment portion 13 is covered, so even if damage occurs, it will not affect the appearance quality of the lid assembly. Simultaneously, this design significantly reduces the stress on the limiting rib 14, lowering the probability of breakage due to excessive stress during production and transportation, thus ensuring the product's appearance quality.

[0053] It should be noted that this utility model does not limit the relative positions of the abutment portion 13 and the mating portion 21 after the cover 1 and the liner 2 are assembled, as long as the mating portion 21 can abut against the abutment portion 13 when the cover 1 and the liner 2 tend to move horizontally. For example, the abutment portion 13 is located horizontally on the side of the mating portion 21 near the limiting rib 14. Alternatively, the abutment portion 13 can be located above or below the mating portion 21, or diagonally above or diagonally below it, so that the mating portion 21 can still abut against the abutment portion 13 in the horizontal direction through the inclined surface fit.

[0054] As a preferred embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 11 As shown, the abutting part 13 is provided with a guide slope 131, and the mating part 21 is provided with a mating slope 211 that mates with the guide slope 131 on the side facing the limiting groove 22. The gap between the guide slope 131 and the mating slope 211 is smaller than the lateral gap between the limiting rib 14 and the limiting groove 22.

[0055] When the cover 1 and the liner 2 tend to move laterally relative to each other, the abutting part 13 and the mating part 21 abut against each other through the inclined surface. On the one hand, this allows the abutting force between the two to be dispersed along the inclined surface, reducing local stress and preventing stress concentration and damage to the abutting part 13. On the other hand, when the cover 1 and the liner 2 are assembled, the guide inclined surface 131 can guide the mating part 21, allowing the mating part 21 to slide along the guide inclined surface 131 to a position where the cover 1 and the liner 2 are centered. This makes the gaps between the limiting ribs 14 and the limiting grooves 22 on both sides closer to equal, which not only improves the overall appearance quality of the pot lid assembly, but also makes the limiting ribs 14 on both sides more evenly stressed, preventing excessive stress on one side of the limiting ribs 14 and damage.

[0056] Furthermore, such as Figure 3 , Figure 7 , Figure 10 , Figure 11 As shown, one end of the abutting part 13 is fixed to the snap-fit ​​part 12, and the thickness of the abutting part 13 gradually increases in the direction close to the snap-fit ​​part 12, so as to form a guide slope 131 on the surface of the abutting part 13.

[0057] The thickness of the abutment portion 13 gradually increases towards the engaging portion 12. This not only increases the structural strength of the abutment portion 13 in that direction, but also allows the abutment force to be dispersed on the guide slope 131 when the mating portion 21 abuts against the abutment portion 13, alleviating localized stress on the abutment portion 13 and reducing the risk of breakage. Simultaneously, the connection between the abutment portion 13 and the engaging portion 12 is the area with the greatest thickness of the abutment portion 13, effectively improving the structural strength at this location and the structural strength of the engaging portion 12. This makes the fit between the engaging portion 12 and the mating portion 21 more stable, ensuring the stability of the connection between the rear ends of the cover 1 and the liner 2 and reducing the possibility of damage to the engaging portion 12.

[0058] Specifically, such as Figure 11 As shown, the snap-fit ​​portion 12 and the abutment portion 13 are arranged at an angle, for example... Figure 11 As shown, the snap-fit ​​portion 12 extends horizontally, and the abutment portion 13 extends vertically. The thickness of the abutment portion 13 gradually increases from the end away from the snap-fit ​​portion 12 to the end closer to the snap-fit ​​portion 12, thereby forming a guide slope 131.

[0059] Preferably, such as Figure 7 , Figure 11 As shown, the abutting part 13 is fixedly connected to the snap-fit ​​part 12 and the limiting rib 14 respectively.

[0060] The abutment portion 13 connects the locking portion 12 and the limiting rib 14 into one unit. It not only acts as a reinforcing rib, improving the structural strength of both the locking portion 12 and the limiting rib 14 and reducing the possibility of damage under stress, but also, when the limiting rib 14 is under stress, it can transfer part of the force to the locking portion 12 through the abutment portion 13. This allows the locking portion 12 and the abutment portion 13 to share the force on the limiting rib 14, thus reducing the stress on the limiting rib 14. Conversely, the limiting rib 14 and the abutment portion 13 can also share the force on the locking portion 12. This makes the force distribution more dispersed when a single structure is under stress, avoiding stress concentration.

[0061] Preferably, the limiting rib 14, the abutting part 13, and the snap-fit ​​part 12 are all protruding ribs on the cover 1, and are formed on the cover 1 by injection molding.

[0062] As a preferred embodiment of this utility model, such as Figure 10 , Figure 11 As shown, the edges on both sides of the notch 15 are folded inward toward the inside of the cover 1 to form a flange, and the flange forms a limiting rib 14. A blocking space 19 is formed between the limiting rib 14 and the inner surface of the cover 1, and the snap-fit ​​part 12 is located in the blocking space 19.

[0063] The edges on both sides of the notch 15 are folded inward to form a flange, which constitutes a limiting rib 14. This improves the uniformity of the appearance of the lid 1 and makes the folding point of the flange smoother, avoiding sharp corners on the surface of the lid assembly. In addition, the flange design allows the edge of the notch 15 to fit more closely with the connecting arm 23, preventing the edge of the notch 15 from lifting relative to the connecting arm 23. Because the flange folds inward to the inside of the lid 1, it forms a shielding space 19 with the inner surface of the lid 1. The snap-fit ​​part 12 is located within the shielding space 19. When the limiting rib 14 engages with the limiting groove 22, the liner 2 and the connecting arm 23 on the liner 2, together with the lid 1, seal and shield the shielding space 19. This allows the snap-fit ​​part 12 and the mating part 21 to engage internally without being exposed on the surface, achieving a hidden design and improving the appearance quality of the lid assembly.

[0064] Furthermore, such as Figures 8 to 11 As shown, the width of the limiting rib 14 gradually increases from top to bottom, so that the surface of the limiting rib 14 facing the inner side of the cover 1 forms a first positioning slope 141, and the limiting groove 22 has a second positioning slope 221 that is adapted to the first positioning slope 141.

[0065] The width of the limiting rib 14 gradually increases downwards, meaning that the width of the limiting rib 14 is larger closer to the lower edge of the cover 1. This makes the lower edge of the notch 15 prone to deformation. By increasing the width of the limiting rib 14, the limiting effect after the limiting rib 14 and the limiting groove 22 are improved, thereby reducing the deformation of the lower end of the cover 1 and making the lower ends of the cover 1 and the liner 2 fit more closely. Simultaneously, during assembly, the first positioning inclined surface 141 and the second positioning inclined surface 221 cooperate to guide the installation of the cover 1 and the liner 2. Under the guidance of the inclined surfaces, the snap-fit ​​part 12 and the mating part 21 naturally complete the snap-fit ​​engagement.

[0066] Specifically, such as Figure 11 As shown, the width of the limiting rib 14 is the distance it protrudes towards the inside of the cover 1.

[0067] It should be noted that in this utility model, the terms "upper," "lower," "top," and "bottom" used to indicate vertical orientation all refer to the pot lid assembly, top cover 1, and liner 2 being in the upright position, that is, the pot lid assembly being closed to the pot body. They do not refer to the pot lid assembly being closed to the pot body. Figure 8 , Figure 10 The inverted state shown.

[0068] Preferably, such as Figure 9 , Figure 11 As shown, the snap-fit ​​part 12 is a horizontally extending snap-fit ​​rib, and a vertically extending reinforcing rib is provided on the side of the snap-fit ​​rib near the limiting rib 14. The reinforcing rib forms the abutment part 13, and the mating part 21 is a mating buckle 212 provided on the rear edge of the connecting arm 23.

[0069] The reinforcing rib extends vertically, while the snap-fit ​​rib extends horizontally, with both extending perpendicularly. This arrangement not only allows the combined structure to form both a horizontal and vertical stop with the mating part 21, but also enhances the overall structural strength of the snap-fit ​​rib and the reinforcing rib, thus strengthening the structure. The mating buckle 212 is located at the rear edge of the connecting arm 23, allowing the snap-fit ​​rib and the mating buckle 212 to engage horizontally. After engagement, this provides a stop in both the vertical and horizontal directions, restricting the relative vertical movement of the cover 1 and the liner 2.

[0070] like Figure 9 As shown, there are two mating buckles 212 arranged vertically to form a groove 213 between them. The engaging rib can extend into the groove 213 to complete the engagement. The mating buckles 212 on the upper and lower sides act as vertical stops for the engaging rib. The mating inclined surface 211 is provided with at least one of the two mating buckles 212, located on the side of the mating buckle 212 facing the limiting groove 22.

[0071] Furthermore, such as Figure 11 As shown, multiple reinforcing ribs 132 are also provided at intervals in the extending direction of the snap-fit ​​portion 12. One end of the reinforcing rib 132 is connected to the snap-fit ​​portion 12, and the other end is connected to the cover 1, so as to further improve the structural strength of the snap-fit ​​portion 12.

[0072] Preferably, such as Figure 11 As shown, a limiting part 133 is also provided on the side of the snap-fit ​​part 12 away from the limiting rib 14, and a limiting space 18 for accommodating the mating part 21 is formed between the abutting part 13 and the limiting part 133.

[0073] The limiting part 133 and the abutting part 13 are located on the left and right sides of the engaging part 12, thus forming a limiting space 18 for accommodating the mating part 21. When the engaging part 12 engages with the mating part 21, both sides of the mating part 21 are stopped and thus confined within the limiting space 18. This limits the relative displacement of the cover 1 and the liner 2 in the left and right directions, improves the relative positional stability, and prevents the cover 1 and the liner 2 from shifting over a large range.

[0074] Specifically, such as Figure 8 , Figure 10 As shown, the cover 1 includes a panel 16 located above the cover 2 and a skirt 17 surrounding the outer periphery of the cover 2. The skirt 17 is provided with a first fixing buckle 171. There are multiple first fixing buckles 171 and they are spaced apart along the circumference of the cover 2. The outer edge of the cover 2 is provided with a second fixing buckle 24 that cooperates with the first fixing buckle 171.

[0075] The cover skirt 17 of the faceplate 1 is provided with multiple first fixing buckles 171 spaced apart around its circumference, which cooperate with the second fixing buckles 24 on the edge of the liner 2, so that the faceplate 1 and the liner 2 are fixed at multiple points around its circumference. This makes the fixing force of the two more evenly distributed around its circumference, improves the connection stability, and prevents the liner 2 from tilting relative to the faceplate 1. At the same time, at the rear end of the two, the snap-fit ​​part 12 and the mating part 21 are used to specifically improve the connection strength in this area, which improves the overall connection effect of the faceplate 1 and the liner 2, avoids the appearance of weak connection areas, and improves product quality.

[0076] Preferably, such as Figure 10 As shown, the length of the first fixing buckle 171 around the circumference of the cover is greater than the length of the locking part 12 around the circumference of the cover.

[0077] This utility model also discloses a cooking appliance, including a pot body and the aforementioned pot lid assembly. The pot body is provided with a connecting seat, which is located between the connecting arms 23 and is rotatably connected to the connecting arms 23 so that the pot lid assembly can rotate relative to the pot body to open or close the pot body.

[0078] The notch 15 and the connecting part together form the connecting groove 11. The connecting groove 11 has a downward-facing opening. The connecting seat of the pot body can extend into the connecting groove 11 through the opening and rotate to connect with the connecting arms 23 on both sides, making the position of the pot lid and the pot body more compact and reducing the gap between the pot lid assembly and the pot body on the appearance surface of the cooking utensil.
