Description

Technical Field

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

[0002] Cooking utensil lids are generally assembled with the pot body in two ways: one-piece and two-piece. Two-piece lids can be removed from the pot body, allowing the pot to be fully opened. One-piece lids are hinged to the pot body at one end and locked to the pot body at the other end through a snap-fit ​​or other structure, allowing the lid to be opened or closed by flipping it over.

[0003] Integrated cooking appliances typically have a lid release button on the lid or pot body, allowing the user to unlock the lid by pressing the button. For cooking appliances with the lid release button located on the pot body, there is usually an installation opening on the side wall of the pot body. The lid release button has a snap-fit ​​structure. During assembly, the lid release button is aligned with the installation opening and pressed in, causing the snap-fit ​​structure to engage with the flange of the installation opening, thus completing the installation of the lid release button.

[0004] However, during the installation of the lid-opening button, there is some interference between the snap-fit ​​structure and the flange of the mounting opening. Therefore, a significant pressing force perpendicular to the surface of the pot's outer shell is required to force the lid-opening button to exert strong pressure on the pot's outer shell, allowing the snap-fit ​​structure to overcome the flange and complete the engagement. Because the drilling operation results in lower structural strength of the pot's outer shell at the mounting opening, there is a risk of damage to the flange or the area around the mounting opening when subjected to the significant pressure from the lid-opening button.

[0005] In addition, in order to improve the quality of cooking utensils, some pots are made of metal. However, the edges of metal outer shells have poor elasticity, which further increases the difficulty of installing the lid opening button. The outer shell often deforms during the installation process, which seriously affects the yield rate of the equipment. Utility Model Content

[0006] This utility model provides a cooking appliance to solve the problem that during the installation of the lid opening button onto the pot body, the pressure exerted by the lid opening button on the outer shell of the pot body is too large, which leads to easy deformation or damage of the outer shell and a low yield rate of the equipment.

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

[0008] A cooking appliance includes a pot body, the pot body includes an outer cover and a lid opening assembly disposed on the outer cover, the lid opening assembly includes a mounting base, the outer cover has a mounting opening for mounting the mounting base, the edge of the mounting opening has a clearance section and a limiting section in the circumferential direction, the mounting base is provided with a stop portion, the mounting base is rotatable relative to the outer cover to have an unlocked state where the stop portion corresponds to the clearance section, and a locked state where the stop portion corresponds to the limiting section.

[0009] In this invention, the mounting opening of the outer cover has a limiting section and a clearance section along its circumferential direction. The limiting section can stop the stop portion of the mounting base to prevent the mounting base from detaching from the mounting opening, while the clearance section can avoid the stop portion, allowing the mounting base to smoothly extend into the mounting opening. This allows the mounting base to be fixed to the mounting opening by rotation. Specifically, after aligning the stop portion and the clearance section, the mounting base is inserted into the mounting opening, allowing the stop portion to enter the interior of the outer cover. During this process, because the clearance section avoids the stop portion, the insertion of the mounting base will not interfere with the outer cover and will not be obstructed. Then, the mounting base is rotated so that the stop portion rotates to a locking state corresponding to the inner side of the limiting section, completing the locking of the mounting base and the outer cover. Throughout the entire installation process, the mounting base will not exert any pressure perpendicular to the surface of the outer cover, thereby greatly reducing the stress on the outer cover, reducing the possibility of deformation, and improving the yield rate. Furthermore, the mounting base does not interfere with the outer cover during installation, making assembly easier and improving efficiency. Similarly, when removing the mounting base, there is no need to apply significant force to pull it out of the mounting opening. Simply rotate the mounting base in the opposite direction to align the stop with the clearance section, switch to the unlocked state, and the mounting base can be easily removed from the mounting opening. This greatly improves the efficiency of assembling and disassembling the cover assembly, and prevents excessive pressure on the outer cover during the process, ensuring the quality of the outer cover.

[0010] The mounting port is also equipped with a fixing structure, and the outer periphery of the mounting base is equipped with a locking structure. When the mounting base is rotated to the locked state, the fixing structure can cooperate with the locking structure to restrict the rotation of the mounting base.

[0011] In this design, to lock the mounting base in the locked state and prevent it from rotating relative to the outer cover and detaching from the mounting opening during use, a fixing structure is provided at the mounting opening, and a locking structure is provided on the mounting base. When the mounting base rotates to the locked state, the cooperation of the fixing structure and the locking structure restricts the rotation of the mounting base, thus confining it to the locked state. At this time, the mounting base cannot rotate relative to the outer cover. This improves the stability of the mounting base, reduces shaking during use, and also improves the installation stability of the mounting base, preventing it from falling out of the mounting opening.

[0012] One of the two structures, the fixed structure and the locking structure, is a snap-fit ​​rib, and the other is a snap-fit ​​groove. The snap-fit ​​rib can deform to engage with the snap-fit ​​groove or disengage from it.

[0013] In this design, the rotation of the mounting base is restricted through the combination of ribs and grooves. This not only simplifies the structure and makes it easy to manufacture, but also eliminates the need for additional locking components, thus saving costs. The deformable snap-fit ​​ribs further reduce the compressive force between the mounting base and the outer cover during assembly. Even if interference occurs between the mounting base and the snap-fit ​​ribs during assembly, the ribs can deform under pressure to avoid strong compression of the mounting base, further alleviating the stress on the outer cover.

[0014] The mounting port has a flange protruding towards the inside of the mounting port. The flange consists of multiple segments spaced apart around the circumference of the mounting port to form a limiting segment. There is a clearance gap between two adjacent flanges to form a clearance segment.

[0015] In this design, multiple flanges are spaced apart along the edge of the mounting opening to form a limiting section, while adjacent flanges form a clearance section. This results in different inner diameters in different areas of the mounting opening in the circumferential direction. The clearance section has a larger inner diameter, allowing the stop to pass smoothly into the outer casing, while the limiting section has a smaller inner diameter, allowing it to stop from the inside of the stop. Simultaneously, the flange design also improves the structural strength of the mounting opening, reducing the possibility of deformation of the outer casing at the mounting opening.

[0016] The mounting port has a reinforcing wall protruding towards the inside of the outer cover, and a flange is located at the end of the reinforcing wall near the inside of the outer cover.

[0017] In this design, the reinforcing wall extends from the edge of the mounting opening into the inner part of the outer cover. This not only further improves the structural strength of the mounting opening but also increases its depth. Furthermore, the flange is located on the inner side of the reinforcing wall, closer to the inside of the pot body. This allows the mounting base to extend into a deeper part of the mounting opening, preventing its outer surface from protruding excessively from the outer cover surface, reducing the height difference between the two and improving the appearance quality of the cooking appliance.

[0018] The reinforced wall has a guide section corresponding to the avoidance section, and the length of the guide section protruding towards the inside of the outer cover gradually increases from the end away from the flange to the end closer to the flange.

[0019] In this design, as the mounting seat rotates, the stop moves from the clearance section to the limiting section. During this process, the stop is guided by the guide section, which gradually protrudes into the outer cover. As the mounting seat rotates, it also moves into the outer cover, allowing the mounting seat to gradually penetrate deeper into the outer cover. This improves the overall compactness of the pot body structure and makes the outer surface of the mounting seat basically flush with the outer surface of the outer cover.

[0020] The stop portion includes a stop protrusion disposed on the outer periphery of the mounting base and protruding outward along the radial direction of the mounting base, and the stop protrusions are spaced apart along the circumference of the mounting base.

[0021] In this design, the stop protrusions can cooperate with the limit section stop on the inner side of the outer cover, thereby preventing the mounting base from detaching from the outer cover. Multiple stop protrusions ensure that the mounting base has multiple areas that stop with the outer cover in the circumferential direction, making the stopping force on the mounting base and the outer cover more even, preventing the mounting base from tilting, and also preventing excessive localized stress on the outer cover, which could lead to deformation or damage.

[0022] The stop protrusion has a guide slope at one end of the mounting base facing the limiting section in the circumferential direction.

[0023] In this design, the guide slope can contact the limiting section to guide the movement, allowing the stop to move smoothly to the inside of the limiting section. This avoids interference between the stop protrusion and the limiting section during the rotation of the mounting base due to machining or assembly errors, which could lead to jamming or assembly problems.

[0024] The outer periphery of the mounting base is also provided with a decorative ring rib, which is located on the side of the stop part away from the inside of the outer cover. There is a limiting gap between the decorative ring rib and the stop part to accommodate the limiting section.

[0025] In this design, decorative ring ribs and stop sections are spaced apart along the axial direction of the mounting base, forming a limiting gap to accommodate the limiting section. This ensures that when the mounting base rotates to the locked position, both the inner and outer sides of the limiting section are stopped, preventing the mounting base from detaching from the mounting opening and restricting its movement towards the outer cover, thus improving the positional stability of the mounting base and reducing wobbling. Simultaneously, the decorative ring ribs also decorate the outer surface of the mounting base, concealing the gap between the mounting base and the mounting opening, and improving the overall appearance of the cooking appliance.

[0026] In the circumferential direction of the mounting port, the length of the limiting section is greater than the length of the avoidance section.

[0027] In this design, the area occupied by the limiting section is larger than that occupied by the clearance section in the circumferential direction of the mounting opening. This increases the restriction on the installation angle of the mounting base, ensuring that the mounting base can only be inserted into the mounting opening when the stop and clearance sections are aligned, thus improving the positioning effect of the mounting base assembly. Furthermore, because the limiting section has a larger area, the stop is more easily aligned with it. Therefore, the mounting base only needs to be rotated a small angle to switch to the locked state, reducing assembly difficulty and improving assembly efficiency. Attached Figure Description

[0047] like Figures 1 to 4 As shown, a cooking appliance includes a pot body, which includes an outer cover 1 and a lid opening assembly 2 disposed on the outer cover 1. The lid opening assembly 2 includes a mounting base 21. The outer cover 1 has a mounting opening 11 for mounting the mounting base 21. The edge of the mounting opening 11 has a clearance section 13 and a limiting section 12 along the circumferential direction. The mounting base 21 is provided with a stop part 211. The mounting base 21 can rotate relative to the outer cover 1 to have an unlocked state where the stop part 211 corresponds to the clearance section 13, and a locked state where the stop part 211 corresponds to the limiting section 12.

[0048] It is understandable that, such as Figure 1 , Figure 10 As shown, the lid opening component 2 also includes a button 22 disposed in the mounting base 21. After the lid opening component 2 is installed, the user can press the button 22 to move the button 22 relative to the mounting base 21, thereby unlocking the lid and the pot body.

[0049] Preferably, such as Figure 1 As shown, the mounting port 11 is located on the front side of the outer cover 1 (facing the user) to facilitate the user's operation of the cover opening assembly 2. It should be noted that this utility model does not limit the material of the outer cover 1; it can be made of plastic or metal.

[0050] Preferably, such as Figure 1 As shown, both the mounting port 11 and the mounting base 21 are circular structures to make the rotation of the mounting base 21 smoother.

[0051] In this invention, the mounting opening 11 of the outer cover 1 has a limiting section 12 and a clearance section 13 along the circumferential direction. The limiting section 12 can stop the stop portion 211 of the mounting base 21 to prevent the mounting base 21 from dislodging from the mounting opening 11. The clearance section 13 can avoid the stop portion 211, allowing the mounting base 21 to smoothly extend into the mounting opening 11. This allows the mounting base 21 to be fixed to the mounting opening 11 by rotation. Specifically, after aligning the stop portion 211 with the clearance section 13, the mounting base 21 is extended into the mounting opening 11, allowing the stop portion 211 to enter the interior of the outer cover 1. Figure 5 , Figure 6 As shown, during this process, because the avoidance section 13 avoids the stop part 211, the insertion of the mounting base 21 will not interfere with the outer cover 1 and will not be obstructed. Then the mounting base 21 is rotated, as... Figure 7 , Figure 8 As shown, the stop part 211 is rotated to a locking state corresponding to the inner side of the limit section 12, thus completing the locking of the mounting base 21 and the outer cover 1.

[0052] Throughout the installation process, the mounting base 21 does not exert any compressive force perpendicular to the surface of the outer cover 1, thereby greatly alleviating the stress on the outer cover 1, reducing the possibility of deformation of the outer cover 1, and improving the yield rate. Furthermore, the mounting base 21 does not interfere with the outer cover 1 during installation, making it easier for assembly personnel to operate and thus improving assembly efficiency.

[0053] Similarly, when disassembling the mounting base 21, there is no need to apply a large force to pull it out of the mounting port 11. Simply rotate the mounting base 21 in the opposite direction so that the stop part 211 aligns with the clearance section 13, switch to the unlocked state, and the mounting base 21 can be easily removed from the mounting port 11. This greatly improves the efficiency of assembling and disassembling the cover assembly 2, and no large compressive force is exerted on the outer cover 1 during the assembly and disassembly process, ensuring the quality of the outer cover 1.

[0054] This invention does not limit the rotation direction of the mounting base 21 when switching from the unlocked state to the locked state. In one embodiment, the limiting segment 12 is located on one side of the clearance segment 13. After the stop part 211 passes through the clearance segment 13, the assembler can rotate the mounting base 21 in a single direction (either counterclockwise or clockwise) to rotate the stop part 211 to the position corresponding to the limiting segment 12. In another embodiment, the limiting segment 12 and the clearance segment 13 are arranged alternately along the circumference of the mounting opening 11, so that the limiting segment 12 is located on both sides of the clearance segment 13. After the stop part 211 passes through the clearance segment 13, the assembler can rotate the stop part 211 to the position corresponding to the limiting segment 12 regardless of whether the mounting base 21 is rotated clockwise or counterclockwise.

[0055] As a preferred embodiment of this utility model, such as Figure 2 , Figure 4 As shown, the mounting port 11 is also provided with a fixing structure along its edge, and the mounting base 21 is provided with a locking structure on its outer periphery. When the mounting base 21 is rotated to the locked state, the fixing structure can cooperate with the locking structure to restrict the rotation of the mounting base 21.

[0056] To lock the mounting base 21 in the locked state and prevent it from rotating relative to the outer cover 1 and dislodging from the mounting opening 11 during use, this design includes a fixing structure in the mounting opening 11 and a locking structure on the mounting base 21. When the mounting base 21 rotates to the locked state, the cooperation of the fixing structure and the locking structure restricts the rotation of the mounting base 21, thus confining it to the locked state. At this time, the mounting base 21 cannot rotate relative to the outer cover 1. This improves the stability of the mounting base 21, reducing shaking during use, and also enhances the installation stability of the mounting base 21, preventing it from falling out of the mounting opening 11.

[0057] Furthermore, such as Figure 2 , Figure 4 As shown, one of the fixing structure and the locking structure is a snap-fit ​​rib 14, and the other is a snap-fit ​​groove 212. The snap-fit ​​rib 14 can deform to engage with the snap-fit ​​groove 212 or disengage from the snap-fit ​​groove 212.

[0058] The rotation of the mounting base 21 is restricted by the cooperation of the rib 213 and the groove structure. This not only makes the structure simple and easy to manufacture, but also eliminates the need for additional locking components, thus saving costs. The deformable snap-fit ​​rib 14 further reduces the compressive force between the mounting base 21 and the outer cover 1 during assembly. Even if the mounting base 21 and the snap-fit ​​rib 14 interfere with each other during assembly, the snap-fit ​​rib 14 can deform under the pressure to avoid strong compression of the mounting base 21, thereby further alleviating the stress on the outer cover 1.

[0059] This embodiment does not limit the deformation method of the drive snap-fit ​​rib 14, which can be one of the following embodiments:

[0060] Example 1: In this example, the snap-fit ​​rib 14 is manually driven by the assembler to deform, thereby engaging with the snap-fit ​​groove 212. In a specific example, such as Figure 6 , Figure 8 As shown, the snap-fit ​​rib 14 is an elastic piece set on the edge of the mounting opening 11, extending towards the inside of the outer cover 1. The snap-fit ​​groove 212 is set on the outer periphery of the mounting base 21. When the mounting base 21 is rotated to the locked state, the elastic piece and the snap-fit ​​groove 212 are aligned. At this time, the assembler can manually bend the elastic piece towards the snap-fit ​​groove 212 to produce plastic deformation, thereby entering the snap-fit ​​groove 212 to complete the fit.

[0061] Example 2: In this example, the snap-fit ​​rib 14 can contact the mounting base 21 during its rotation, and then undergo elastic deformation under the push of the mounting base 21, thereby engaging with the snap-fit ​​groove 212. For example, in a specific example, the snap-fit ​​rib 14 is located at the edge of the mounting opening 11, the snap-fit ​​groove 212 is located on the outer periphery of the mounting base 21, and the snap-fit ​​groove 212 has ribs 213 on both sides. During the rotation of the mounting base 21 to the locked state, the ribs 213 compress the snap-fit ​​rib 14 and push it to undergo elastic deformation, allowing it to pass over the ribs 213. Then, as the mounting base 21 continues to rotate, the snap-fit ​​rib 14 is snapped into the snap-fit ​​groove 212 under its own elastic force.

[0062] It should be noted that in this embodiment, the snap-fit ​​rib 14 can be a fixing structure, disposed on the edge of the mounting opening 11, and the snap-fit ​​groove 212 is a locking structure, disposed on the mounting base 21. Of course, the snap-fit ​​rib 14 can also be a locking structure, disposed on the mounting base 21, and the snap-fit ​​groove 212 is a fixing structure, disposed on the edge of the mounting opening 11; this is not limited here. Furthermore, this embodiment does not limit the formation method of the snap-fit ​​groove 212; the mounting opening 11 and its edge, or the mounting base 21, can be partially recessed to form the snap-fit ​​groove 212, or as shown in the example below. Figure 2As shown, two protruding ribs 213 are provided on the edge of the mounting port 11 or the mounting base 21, and a snap-fit ​​groove 212 is formed between the two protruding ribs 213, which is not limited here.

[0063] In a preferred embodiment, such as Figure 4 , Figure 6 , Figure 8 As shown, the mounting port 11 has a flange 16 protruding towards the inside of the mounting port 11. The flange 16 is composed of multiple segments spaced apart along the circumference of the mounting port 11 to form a limiting segment 12. There is a clearance gap 161 between two adjacent flanges 16 to form a clearance segment 13.

[0064] Multiple flanges 16 are spaced apart along the edge of the mounting opening 11 to form a limiting section 12. Adjacent flanges 16 form a clearance section 13, resulting in different inner diameters in different areas of the mounting opening 11 in the circumferential direction. The inner diameter of the clearance section 13 is larger, allowing the stop part 211 to pass smoothly into the interior of the outer cover 1, while the inner diameter of the limiting section 12 is smaller, allowing it to stop the stop part 211 from the inside. At the same time, the design of the flanges 16 also improves the structural strength of the mounting opening 11 and reduces the possibility of deformation of the outer cover 1 at the mounting opening 11.

[0065] Furthermore, such as Figure 4 , Figure 6 , Figure 8 As shown, the mounting port 11 has a reinforcing wall 15 protruding towards the inside of the outer cover 1 along its edge, and a flange 16 is located at one end of the reinforcing wall 15 near the inside of the outer cover 1.

[0066] The reinforcing wall 15 extends from the edge of the mounting opening 11 into the outer cover 1, which further improves the structural strength of the mounting opening 11 and increases the depth of the mounting opening 11. The flange 16 is located inside the reinforcing wall 15, closer to the inside of the pot body, so that the mounting base 21 can extend into a deeper position of the mounting opening 11, so that its outer surface does not protrude too much from the surface of the outer cover 1, reducing the difference between the two and improving the appearance quality of the cooking appliance.

[0067] Meanwhile, the reinforcing wall 15 extends into the outer cover 1, forming a guide channel for the installation of the mounting base 21, so that the mounting base 21 can extend into the mounting opening 11 along the axial direction of the mounting opening 11 under the guidance of the reinforcing wall 15.

[0068] The reinforcing wall 15 has a guide section 151 corresponding to the avoidance section 13. The length of the guide section 151 protruding towards the inside of the outer cover 1 gradually increases from the end away from the flange 16 to the end closer to the flange 16.

[0069] Furthermore, such as Figure 4As shown, during the rotation of the mounting base 21, the stop part 211 moves from the avoidance section 13 to the limiting section 12. The stop part 211 is guided by the guide section 151, and the guide section 151 gradually protrudes into the outer cover 1. During the rotation of the mounting base 21, it also moves into the outer cover 1, so that the position of the mounting base 21 gradually goes deeper, thereby improving the overall structural compactness of the pot body and making the outer surface of the mounting base 21 basically flush with the outer surface of the outer cover 1.

[0070] Preferably, such as Figure 2 As shown, the stop portion 211 includes a stop protrusion 215 disposed on the outer periphery of the mounting base 21 and protruding outward along the radial direction of the mounting base 21. The stop protrusion 215 is spaced apart along the circumference of the mounting base 21.

[0071] The stop protrusion 215 can cooperate with the stop of the limiting section 12 on the inner side of the outer cover 1, thereby preventing the mounting seat 21 from disengaging from the outer cover 1. The stop protrusion 215 is multiple, so that the mounting seat 21 has multiple areas that stop with the outer cover 1 in the circumferential direction, making the stopping force on the mounting seat 21 and the outer cover 1 more uniform, preventing the mounting seat 21 from tilting, and also preventing the outer cover 1 from being deformed or damaged due to excessive local force.

[0072] Furthermore, such as Figure 2 As shown, the stop protrusion 215 has a guide slope 216 at one end of the mounting base 21 facing the limiting section 12 in the circumferential direction.

[0073] The guide slope 216 can contact the limiting section 12 to play a motion guiding role, so that the stop part 211 can move smoothly to the inside of the limiting section 12. This avoids interference between the stop protrusion 215 and the limiting section 12 during the rotation of the mounting base 21 due to processing errors or assembly errors, which could lead to a jamming feeling or assembly problems.

[0074] Specifically, in one embodiment, the guide slope 216 can be formed by making the thickness of a local area of ​​the stop protrusion 215 gradually change in the circumferential direction. For example, the thickness of the stop protrusion 215 is smallest at the end near the limiting segment 12, and the thickness of the stop protrusion 215 gradually increases as it extends away from the limiting segment 12, thereby forming the guide slope 216.

[0075] In one embodiment, the mounting base 21 can rotate in one direction (e.g., counterclockwise or clockwise) to engage the limiting segment 12 with the stop portion 211, in which case the guide slope 216 is provided at one end of the stop protrusion 215. In another embodiment, the mounting base 21 can rotate in both directions (counterclockwise and clockwise) to achieve the engagement between the stop portion 211 and the limiting segment 12, in which case the guide slope 216 can be provided at both ends of the stop protrusion 215.

[0076] As a preferred embodiment, such as Figure 2 , Figure 9 , Figure 10 As shown, a decorative ring rib 214 is also provided on the outer periphery of the mounting base 21. The decorative ring rib 214 is located on the side of the stop portion 211 away from the inside of the outer cover 1. There is a limiting gap between the decorative ring rib 214 and the stop portion 211 for accommodating the limiting segment 12.

[0077] Decorative ring ribs 214 and stop portions 211 are spaced apart along the axial direction of the mounting base 21, forming a limiting gap between them to accommodate the limiting section 12. Thus, when the mounting base 21 rotates to the locked state, both the inner and outer sides of the limiting section 12 are stopped, preventing the mounting base 21 from detaching from the mounting opening 11 and restricting its movement into the outer cover 1, improving the positional stability of the mounting base 21 and reducing wobbling. Simultaneously, the decorative ring ribs 214 also decorate the outer surface of the mounting base 21, concealing the gap between the mounting base 21 and the mounting opening 11, improving the overall appearance of the cooking appliance.

[0078] Preferably, such as Figure 4 As shown, in the circumferential direction of the mounting port 11, the length of the limiting segment 12 is greater than the length of the avoidance segment 13.

[0079] In the circumferential direction of the mounting opening 11, the area occupied by the limiting section 12 is larger than that occupied by the clearance section 13. On the one hand, this increases the restriction on the installation angle of the mounting base 21. Only when the stop part 211 is aligned with the clearance section 13 can the mounting base 21 be inserted into the mounting opening 11, thus improving the positioning effect of the mounting base 21 assembly. On the other hand, because the area of ​​the limiting section 12 is larger, the stop part 211 is easier to align with the limiting section 12. Therefore, the mounting base 21 only needs to be rotated by a small angle to switch to the locked state, thereby reducing the assembly difficulty and improving the assembly efficiency.
