Description
Technical Field
[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a pot cover assembly and a cooking appliance. Background Art
[0002] The pot covers of existing cooking appliances usually include a top cover and a side cover. The top cover forms the top appearance surface of the pot cover assembly, and the side cover forms the side appearance surface of the pot cover assembly. Among them, in order to optimize the production process and improve the aesthetics, more and more top covers are processed by a non-spraying process. That is, when processing the top cover, decorative powder and the like are added to the molten plastic, and then injected into a mold to form the top cover, thus omitting steps such as spraying a coating.
[0003] However, the glue inlet position of the top cover is usually set at the center or one side of the top cover. During the injection molding process, after the plastic enters the mold through the glue inlet, it will be divided into multiple strands to fill the mold. And at the intersection of multiple strands of plastic, an obvious weld line will be formed. After molding, the weld line is located on the appearance surface of the top cover, which will cause appearance defects, affecting the aesthetics and use experience of the cooking appliance.
[0004] In addition, some top covers are also provided with decorative accessories. In order to meet the installation of the decorative accessories, a groove-shaped installation structure or a convex installation structure is often processed on the top cover. The addition of these installation structures makes the surface of the top cover, that is, the runner in the mold, more tortuous. During the injection molding process, multiple strands of plastic will intersect in multiple areas, or there will be problems such as uneven flow velocity and poor flow. After molding, multiple weld lines will appear on the surface of the top cover, or appearance defects such as lack of plastic and shrinkage will occur, resulting in a decrease in the yield rate of the product. Summary of the Utility Model
[0005] The utility model provides a pot cover assembly and a cooking appliance to solve the problems that appearance defects such as weld lines appear on the appearance surface during the injection molding process of the top cover, especially the top cover with an installation structure, resulting in a decrease in appearance quality and yield rate.
[0006] The technical solution adopted by the utility model is as follows:
[0007] A pot cover assembly includes a side cover and a top cover. The side cover forms the side appearance surface of the pot cover assembly, and the top cover forms the top appearance surface of the pot cover assembly. The pot cover assembly further includes a decorative ring disposed on the top cover. An installation groove adapted to the shape of the decorative ring is provided on the upper surface of the top cover. The decorative ring is assembled in the installation groove, and a glue injection port is provided at the bottom of the installation groove.
[0008] The pot cover assembly of the utility model further has the following additional technical features:
[0009] The installation groove has an inner groove wall close to the center of the top cover and an outer groove wall far from the center of the top cover, and the wall thickness of the inner groove wall is smaller than that of the outer groove wall.
[0010] The top cover includes an operation area surrounded by the installation groove and a decoration area located outside the installation groove, and the wall thickness of the decoration area is greater than that of the operation area.
[0011] The area of the operation area is smaller than that of the decoration area.
[0012] The glue injection port is located on the lower side surface of the top cover.
[0013] The top cover includes an operation area surrounded by the installation groove and a decoration area located outside the installation groove. The decoration ring is provided with a first buckle and a second buckle extending downward. The first buckle has a first clamping section extending towards the center of the top cover, and the second buckle has a second clamping section extending towards the edge of the top cover. The first clamping section is used for clamping and fixing with the operation area, and the second clamping section is used for clamping and fixing with the decoration area.
[0014] The decoration ring has an inner support rib and an outer support rib. The outer support rib surrounds the outside of the inner support rib. The first buckle is arranged on the inner support rib, and the second buckle is arranged on the outer support rib.
[0015] The top cover and the side cover are of a split structure. The side cover is provided with a first annular rib and a second annular rib surrounding the outside of the first annular rib. A positioning area is formed between the first annular rib and the second annular rib. The first annular rib and / or the second annular rib is provided with a positioning protrusion extending towards the inside of the positioning area, and the top cover is provided with a matching protrusion cooperating with the positioning protrusion.
[0016] The first annular rib forms an opening. The first annular rib has a support rib position extending towards the inside of the opening. The support rib positions are multiple and are evenly arranged along the circumferential direction of the side cover. The support rib positions are used for supporting the top cover.
[0017] The present utility model also discloses a cooking appliance, which includes a pot body having a cooking cavity, and further includes the above-mentioned pot cover assembly; the pot cover assembly can be removably placed on the pot body to open or cover the cooking cavity; alternatively, one end of the pot cover assembly is rotatably connected to the pot body so that the pot cover assembly can be flipped relative to the pot body to open or cover the cooking cavity.
[0018] Due to the adoption of the above technical solutions, the beneficial effects obtained by the present utility model are as follows:
[0019] 1. In the utility model, the glue injection port is arranged at the bottom of the installation groove. On the one hand, after the glue injection molding, the structural defects formed at the glue injection port (for example, a protruding column formed at the glue injection port, or a notch formed after the column is sheared, etc.) can be covered by the decorative ring after the decorative ring is installed in the installation groove, so that the structural defects will not be exposed on the appearance surface of the pot cover assembly, thereby improving the appearance quality of the pot cover assembly and improving the user experience.
[0020] On the other hand, during the injection process, the plastic entering from the injection port is divided into two streams, one of which flows into the flow channel in the outer area of the installation groove, and flows and fills in the flow channel, eventually forming the area where the top cover is located outside the installation groove, and the other flows into the flow channel in the inner area of the installation groove, and flows and fills in the flow channel, eventually forming the area where the top cover is located inside the installation groove. The two streams of plastic flow on both sides of the inside and outside of the installation groove respectively, and eventually meet in the installation groove, so the final bonding line is also located in the installation groove. After the decorative ring is assembled, it can also block the appearance defects such as bonding lines or flow marks produced during the processing process, ensure the appearance quality of the pot cover assembly, and improve the yield rate.
[0021] 2. As a preferred embodiment of the present invention, the mounting groove has an inner groove wall close to the center of the top cover, and an outer groove wall away from the center of the top cover, and the wall thickness of the inner groove wall is less than the wall thickness of the outer groove wall. The mounting groove is designed in an annular shape, so that two inner and outer regions are formed on the top cover, wherein the area of the region located outside the mounting groove is larger, and the area of the region located inside the mounting groove is smaller. That is to say, during the injection molding process, the flow channel outside the mounting groove is longer than the inner side, so it takes longer time to fill, which may cause the inner area to overflow from the mounting groove to the outer area after being filled, resulting in the appearance of the bonding line on the outer surface of the outer area. In this embodiment, by reducing the wall thickness of the inner groove wall to be smaller than the wall thickness of the outer groove wall, the plastic flows inwardly after entering the injection port. The resistance is greater, so it is easier to flow outward, so that the plastic flows to the outer area of the mounting groove first, and the flow speed of the plastic in the outer area is increased, so that the outer area is first filled with plastic, and then flows to the inner area, and finally the outer plastic and the inner plastic are completed in the mounting groove. Convergence.
[0022] 3. As a preferred embodiment of the present invention, the glue injection port is located on the lower side of the top cover. The glue injection port is set on the lower side of the top cover, that is, the side of the top cover away from the appearance surface, so as to further ensure that defects such as the joining line, flow mark and shrinkage generated during the injection molding process will not appear on the appearance surface of the pot cover assembly. Even if the joining line is not formed in the installation groove, but appears on the lower side of the top cover, when the top cover and the side cover are assembled, it will not be exposed to the outside and cannot be seen by the user.
[0023] 4. As a preferred embodiment of the present utility model, the top cover includes an operation area surrounded by an installation groove and a decoration area located outside the installation groove. The decorative ring is provided with a first buckle and a second buckle extending downward. The first buckle has a first clamping section extending toward the center of the top cover, and the second buckle has a second clamping section extending toward the edge of the top cover. The first clamping section is used for clamping and fixing with the operation area, and the second clamping section is used for clamping and fixing with the decoration area. The decorative ring is provided with two sets of buckles. The first buckle is used for clamping and fixing with the operation area inside the installation groove, and the second buckle is used for clamping and fixing with the decoration area outside the installation groove, making the fixation of the decorative ring more stable and reliable. It can not only limit the inward shaking of the decorative ring but also limit the outward shaking of the decorative ring.
[0024] 5. As a preferred embodiment of the present utility model, the top cover and the side cover are of a split structure. The side cover is provided with a first annular rib and a second annular rib surrounding the outside of the first annular rib. The first annular rib forms an opening. The first annular rib has a support rib position extending toward the inside of the opening. The support rib positions are multiple and are evenly arranged along the circumferential direction of the side cover. The support rib positions are used for supporting the top cover. The top cover is correspondingly arranged at the opening. Since there is no support structure for the top cover at the opening, when the top cover is heated or subjected to a downward pressure, it is prone to deform downward, resulting in serious appearance defects and quality defects on the top surface of the pot lid assembly. By providing a support rib position extending toward the inside of the opening on the first annular rib, the support rib positions form a uniform supporting force for the top cover in the circumferential direction of the pot lid assembly. When the top cover has a tendency to sink, it is subjected to an upward supporting force from the support rib positions to resist the deformation of the top cover, improving the stability of the position and posture of the top cover.

Moreover, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
[0050] As Figures 1 to 3 shown, a pot lid assembly includes a side lid 1 and a top lid 2. The side lid 1 constitutes the side external surface of the pot lid assembly, and the top lid 2 constitutes the top external surface of the pot lid assembly. The pot lid assembly further includes a decorative ring 3 disposed on the top lid 2. An installation groove 21 adapted to the shape of the decorative ring 3 is provided on the upper surface of the top lid 2. The decorative ring 3 is assembled in the installation groove 21, and a glue injection port 211 is provided at the bottom of the installation groove 21.
[0051] As Figure 2 、 Figure 3, Figure 6 As shown, the decorative ring 3 is a closed annular structure at the head and tail, thus dividing the top cover 2 into a region surrounded by the decorative ring 3 and a region outside the decorative ring 3. Preferably, as Figure 1 , Figure 2 shown, functional components such as the handle 4 and the exhaust valve 5 of the pot lid assembly are arranged in the region surrounded by the decorative ring 3, and the top cover 2 is correspondingly provided with mounting openings 22 for mounting components such as the handle 4 and the exhaust valve 5.
[0052] Among them, the present invention does not limit the setting position of the decorative ring 3, which can be, as shown in Figures 1 to 3 , in the central region of the top cover 2, enclosing a region with a smaller area, or in the edge region of the top surface, so as to form a decorative structure at a position close to the edge of the top cover 2, and no limitation is made here.
[0053] Preferably, as shown in Figure 4 , the top cover 2 is a plate-like structure, and its upper surface can be a planar structure, an arc surface structure, or an inclined surface structure that gradually decreases from one end to the other end, so as to form different appearance styles.
[0054] As shown in Figure 5 , the cross-section of the installation groove 21 is a U-shaped groove with an opening 11 at the top.
[0055] In the present invention, the glue injection port 211 is arranged at the bottom of the installation groove 21. On the one hand, after glue injection molding, structural defects formed at the glue injection port 211 (such as a raised column formed at the glue injection port 211, or a notch formed after shearing the column, etc.) can be blocked by the decorative ring 3 after the decorative ring 3 is installed in the installation groove 21, so that the structural defects will not be exposed on the appearance surface of the pot lid assembly, thereby improving the appearance quality of the pot lid assembly and the use experience.
[0056] On the other hand, during the glue injection process, the plastic entering from the glue injection port 211 is divided into two strands. One strand flows through the outer groove wall of the installation groove 21 into the flow channel in the outer region of the installation groove 21 and flows and fills in the flow channel, and finally forms the region of the top cover 2 outside the installation groove 21. The other strand flows through the inner groove wall of the installation groove 21 into the flow channel in the inner region of the installation groove 21 and flows and fills in the flow, and finally forms the region of the top cover 2 inside the installation groove 21. The two strands of plastic flow respectively inside and outside the installation groove 21 and finally converge inside the installation groove 21. Therefore, the resulting weld line is also located inside the installation groove 21 (the weld line can be located at the bottom of the installation groove 21 or on the side groove wall of the installation groove 21). After the decorative ring 3 is assembled, it can also block appearance defects such as weld lines or flow marks generated during the processing, ensure the appearance quality of the pot lid assembly, and improve the yield rate.
[0057] Preferably, as Figure 3 shown, the installation groove 21 is in the shape of a runway circle, and the glue injection port 211 is arranged at one end in the length direction.
[0058] As a preferred embodiment of the present utility model, as Figure 5 shown, the installation groove 21 has an inner groove wall 213 close to the center of the top cover 2 and an outer groove wall 214 far from the center of the top cover 2. The wall thickness L1 of the inner groove wall 213 is smaller than the wall thickness L2 of the outer groove wall 214.
[0059] The installation groove 21 is in an annular design, thus forming two inner and outer regions on the top cover 2. Among them, the area of the region outside the installation groove 21 is larger, while the area of the region inside the installation groove 21 is smaller. That is to say, during the injection molding process, the runner outside the installation groove 21 is longer than that inside. Therefore, it takes longer to fill, which may cause the plastic to overflow from the inside of the installation groove 21 to the outside region after the inside region is filled, resulting in the appearance of the weld line on the outside region. In this embodiment, by reducing the wall thickness of the inner groove wall 213 to be smaller than that of the outer groove wall 214, when the plastic enters the glue injection port 211, the resistance to flowing inward is greater, so it is easier to flow outward. Thus, the plastic preferentially flows to the outside region of the installation groove 21, and the flow rate of the plastic in the outside region is increased. Furthermore, the outside region is preferentially filled with plastic, and then it flows to the inside region. Finally, the plastic outside and the plastic inside converge in the installation groove 21.
[0060] In a specific embodiment, the wall thickness of the outer groove wall 214 is twice that of the inner groove wall 213. Specifically, the wall thickness L1 of the inner groove wall 213 is 0.7 mm, and the wall thickness L2 of the outer groove wall 214 is 1.4 mm.
[0061] Preferably, in one embodiment, as Figure 5 shown, the top cover 2 includes an operation area 24 surrounded by the installation groove 21 and a decoration area 23 located outside the installation groove 21. The wall thickness L3 of the decoration area 23 is greater than the wall thickness L4 of the operation area 24.
[0062] Since the area of the decoration area 23 is larger, by increasing the wall thickness of the decoration area 23, the width of the runner during the injection molding process is also larger. The resistance to the flow of the plastic in the decoration area 23 is smaller than that of the plastic flowing in the operation area 24. Furthermore, the flow rate of the plastic in the decoration area 23 is greater than that of the plastic in the operation area 24. Thus, the decoration area 23 is preferentially filled with plastic. At this time, the filling in the operation area 24 is not completed. Then, the plastic in the decoration area 23 flows to the inside of the top cover 2. Finally, the plastic in the decoration area 23 and the plastic in the operation area 24 converge in the installation groove 21.
[0063] In a specific embodiment, the wall thickness L3 of the decoration area 23 is 2.4 mm, and the wall thickness L4 of the operation area 24 is 1.8 mm.
[0064] It should be noted that the above two implementation modes can be implemented independently of each other or in combination. Figure 5 As shown, based on the fact that the wall thickness of the outer groove wall 214 of the installation groove 21 is greater than the wall thickness of the inner groove wall 213, the wall thickness of the decorative area 23 is further made greater than the wall thickness of the operating area 24, so as to greatly increase the flow rate of the plastic flowing to the decorative area 23 and flowing in the decorative area 23, and slow down the flow rate of the plastic flowing to the operating area 24 and flowing in the operating area 24.
[0065] Furthermore, if Figure 1 , Figure 2 As shown, the area of the operation area 24 is smaller than the area of the decoration area 23, and the functional components of the pot cover assembly such as the handle 4 and the exhaust valve 5 are arranged in the operation area 24. A significant dividing line is formed on the upper surface of the pot cover assembly to separate the two areas, so as to realize the functional zoning of the components on the surface of the pot cover assembly, which improves the appearance and also facilitates the user to understand and use the functions of the cooking utensil.
[0066] As a preferred embodiment, Figure 3 As shown, the glue injection port 211 is located on the lower side of the top cover 2. The glue injection port 211 is set on the lower side of the top cover 2, that is, the side of the top cover 2 away from the appearance surface, so as to further ensure that defects such as the joining line, flow mark and shrinkage generated during the injection molding process will not appear on the appearance surface of the pot cover assembly. Even if the joining line is not formed in the installation groove 21, but appears on the lower side of the top cover 2, when the top cover 2 and the side cover 1 are assembled, it will not be exposed to the outside and cannot be seen by the user.
[0067] It is understandable that after the injection molding is completed, the excess plastic will solidify at the injection port 211 to form a raised structure. At this time, the raised structure can be sheared to make the surface smoother. The injection port 211 is set on the lower side of the top cover 2, which makes it simpler and more convenient to handle the excess plastic at the injection port 211.
[0068] As a preferred embodiment of the present invention, Figure 6 , Figure 7 , Figure 11As shown in the figure, the top cover 2 includes an operation area 24 surrounded by the installation groove 21 and a decoration area 23 located outside the installation groove 21. The decorative ring 3 is provided with a first buckle 33 and a second buckle 34 extending downward. The first buckle 33 has a first clamping section 331 extending toward the center of the top cover 2, and the second buckle 34 has a second clamping section 341 extending toward the edge of the top cover 2. The first clamping section 331 is used for clamping and fixing with the operation area 24, and the second clamping section 341 is used for clamping and fixing with the decoration area 23.
[0069] The decorative ring 3 is provided with two groups of buckles. The first buckle 33 is used for clamping and fixing with the operation area 24 inside the installation groove 21, and the second buckle 34 is used for clamping and fixing with the decoration area 23 outside the installation groove 21, making the fixation of the decorative ring 3 more stable and reliable. It can not only limit the shaking of the decorative ring 3 toward the inside but also limit the shaking of the decorative ring 3 toward the outside.
[0070] In this embodiment, the clamping methods of the first clamping section 331 and the second clamping section 341 are not limited. In one embodiment, the installation groove 21 has an inner groove wall 213 and an outer groove wall 214. Among them, the inner groove wall 213 and the outer groove wall 214 are both provided with clamping structures for cooperating with the first clamping section 331 and the second clamping section 341, so that the first clamping section 331 and the second clamping section 341 are respectively fixed in cooperation with the clamping structures. For example, the inner groove wall 213 and the outer groove wall 214 are both provided with clamping grooves, and the first clamping section 331 and the second clamping section 341 are clamped and matched with the clamping grooves.
[0071] In another embodiment, as Figure 3 shown, through holes 212 are provided at the bottom of the installation groove 21 corresponding to the first buckle 33 and the second buckle 34. During assembly, the first buckle 33 and the second buckle 34 are passed through the through holes 212, and then clamped and matched with the lower ends of the two side groove walls of the installation groove 21.
[0072] Specifically, as Figure 6 shown, the first buckle 33 and the second buckle 34 are both evenly spaced along the circumferential direction of the decorative ring 3, and the first buckle 33 and the second buckle 34 are alternately arranged.
[0073] Preferably, as Figure 6 shown, one of the first buckles 33 is arranged at one end of the decorative ring 3, and the second buckle 34 is arranged at the opposite end; or, at the opposite ends of the decorative ring 3, the number of the first buckles 33 and / or the second buckles 34 is different. For example, as Figure 6 shown, one second buckle 34 is arranged at one end in the length direction of the decorative ring 3, and two first buckles 33 are arranged at the opposite end. This plays a role in positioning and anti-fooling during the installation of the decorative ring 3, limits the installation direction of the decorative ring 3, and reduces the assembly difficulty.
[0074] Further, as shown in Figure 6 , Figure 7 , Figure 11 , the decorative ring 3 has an inner support rib 32 and an outer support rib 31. The outer support rib 31 surrounds the outside of the inner support rib 32. The first buckle 33 is arranged on the inner support rib 32, and the second buckle 34 is arranged on the outer support rib 31. Both the inner support rib 32 and the outer support rib 31 are annular rib positions extending along the circumferential direction of the decorative ring 3. Among them, the inner support rib 32 is used to cooperate with the inner groove wall 213 of the installation groove 21 for positioning, and the outer support rib 31 is used to cooperate with the outer groove wall 214 of the installation groove 21 for positioning.
[0075] In addition, arranging the first buckle 33 on the inner support rib 32 and the second buckle 34 on the outer support rib 31 can also improve the strength of the first buckle 33 and the second buckle 34, and reduce the risk of damage to the first buckle 33 and the second buckle 34 due to excessive extrusion force.
[0076] It should be noted that the present utility model does not limit the assembly method of the top cover 2 and the side cover 1. In one implementation manner, the top cover 2 and the side cover 1 are integrally formed, and the two are integrally processed by injection molding.
[0077] In another implementation manner, as shown in Figure 13 , the top cover 2 and the side cover 1 are of a split structure. Among them, the top cover 2 is formed by injection molding, and the processing method of the side cover 1 is not limited. It can also be injection molded, or can be processed and formed by other methods.
[0078] Further, as shown in Figure 3 , Figure 8 , Figure 9 , the side cover 1 is provided with a first annular rib 13 and a second annular rib 12 surrounding the outside of the first annular rib 13. A positioning area 14 is formed between the first annular rib 13 and the second annular rib 12. The first annular rib 13 and / or the second annular rib 12 is provided with a positioning protrusion 15 extending into the positioning area 14. The top cover 2 is provided with a mating protrusion 25 that cooperates with the positioning protrusion 15.
[0079] Specifically, as shown in Figure 3 , Figure 9 , the mating protrusion 25 is an arc-shaped rib position extending along the circumferential direction of the top cover 2. The positioning protrusion 15 is located inside and / or outside the arc-shaped rib position. During assembly, the positioning protrusion 15 abuts against the mating protrusion 25 from inside to outside or from outside to inside, so as to position the top cover 2 and prevent the top cover 2 from shaking laterally relative to the side cover 1.
[0080] Furthermore, a clamping portion 16 is also provided within the positioning area 14, and a cooperating portion 26 is correspondingly provided on the top cover 2, so that the top cover 2 is clamped and fixed to the side cover 1. As Figure 3 , Figure 9 shown, a plurality of cooperating portions 26 and cooperating protrusions 25 are evenly spaced along the circumferential direction of the top cover 2, and the positioning protrusions 15 and the clamping portion 16 are correspondingly provided with the structures they cooperate with.
[0081] In addition, a screw post 17 is provided in the positioning area 14, and a fixing post 27 is also provided on the top cover 2, so as to fasten and connect the two with fasteners such as screws.
[0082] Preferably, as Figure 8 , Figure 9 , Figure 10 , Figure 12 shown, the first annular rib 13 encloses an opening 11, and the first annular rib 13 has a support rib position 131 extending towards the inside of the opening 11. There are a plurality of support rib positions 131 and they are evenly arranged along the circumferential direction of the side cover 1. The support rib position 131 is used to support the top cover 2.
[0083] The top cover 2 is correspondingly arranged at the opening 11. Since there is no support structure for the top cover 2 at the opening 11, when the top cover 2 is heated or subjected to a downward pressure, it is prone to deform downward, resulting in serious appearance defects and quality defects on the top surface of the pot lid assembly. By providing the support rib position 131 extending towards the inside of the opening 11 on the first annular rib 13, the support rib position 131 forms a uniform supporting force for the top cover 2 in the circumferential direction of the pot lid assembly. When the top cover 2 has a tendency to sink, it is subjected to the upward supporting force of the support rib position 131 to resist the deformation of the top cover 2, improving the stability of the position and attitude of the top cover 2.
[0084] Specifically, the support rib position 131 has a bearing portion for supporting the top cover 2 and a strengthening portion located below the bearing portion, so that the cross-section of the support rib position 131 is a T-shaped structure. As Figure 12 shown, after assembly, a gap is reserved between the support rib position 131 and the top cover 2. This gap is preferably 0.2 mm. So that when the top cover 2 is not deformed, they do not contact each other. Only when the top cover 2 sinks downward until it contacts the support rib position 131, the support rib position 131 forms an upward supporting force for the top cover 2.
[0085] The present utility model also discloses a cooking appliance, including a pot body having a cooking cavity, and further including the above-mentioned pot lid assembly; the pot lid assembly can be removably placed on the pot body to open or close the cooking cavity; or, one end of the pot lid assembly is rotatably connected to the pot body, so that the pot lid assembly can be flipped relative to the pot body to open or close the cooking cavity.
