Description

Technical Field

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

[0002] Existing cooking appliances, such as rice cookers and pressure cookers, generally consist of a cooker body and a lid. The front end of the cooker body has a locking part. The lid includes a top cover, a liner, and a spring-loaded element. The top cover has an opening button. A button plate is rotatably mounted on the front side of the liner. The button plate includes a pressing part and a locking part located on both sides of its rotation axis. The spring-loaded element acts on the button plate to move the locking part backward when the lid is closed, maintaining its engagement with the locking part. To open the lid, pressing down on the opening button moves the pressing part of the button plate downward, causing the locking part to tilt forward and disengage from the locking part, thus opening the lid.

[0003] To facilitate the installation of the cover opening button, existing structures typically include a U-shaped notched shaft hole on the cover. One end of the cover opening button has a pivot, which is inserted into the cover along the notch of the shaft hole, allowing the button to rotate around the pivot. However, in practical applications, due to factors such as pivot positioning requirements, machining errors, assembly errors, and deformation of the cover and button, the cover opening button may shift along its own axis. This shift can alter the contact area between the button and the button panel, causing the button panel to malfunction and fail to open the cover.

[0004] Existing technology discloses an assembly structure for an opening button, including a cover and an opening button rotatably mounted on the cover. The back of the cover has a limiting structure to restrict the opening button from sliding along its own rotation axis within its working stroke. The limiting structures are located on both sides of the opening button. Existing covers are generally made of plastic, with the front of the cover being part of the cookware's exterior. To meet this requirement, the limiting structure needs to extend as far as possible towards the cover, resulting in a large height dimension. The wall thickness of the part of the cover connected to the limiting structure is thicker than other areas, causing noticeable shrinkage pits on the front of the cover, reducing product quality. Utility Model Content

[0005] This application provides a cooking appliance to solve the technical problem that the lid opening button of existing cooking appliances is prone to slipping along its own rotation axis during actual use, resulting in the lid not opening properly.

[0006] The technical solution adopted in this application is as follows:

[0007] A cooking appliance includes a pot body and a pot lid. The pot lid includes a top cover, a liner, a lid opening button, and a button plate. The button plate is rotatably connected to the liner to lock or unlock with the pot body. The lid opening button is rotatably connected to the top cover to drive the button plate to rotate. The liner is provided with a limiting structure for restricting the movement of the lid opening button along its rotation axis. The limiting structure includes two first limiting ribs that are located on two opposite sides of the lid opening button and extend from the liner toward the top cover.

[0008] This application provides two first limiting ribs extending towards the top cover and positioned on opposite sides of the opening button on the liner. These two first limiting ribs restrict the movement of the opening button along its rotation axis, ensuring that the contact area between the opening button and the button plate remains in a preset position. This allows the button plate to respond quickly and open the lid when the opening button is triggered, avoiding the problem of unresponsive opening. Since the liner is an internal component and its upper surface does not form part of the outer surface of the lid, the first limiting ribs extending towards the top cover on the liner prevent shrinkage pits from becoming external, even if shrinkage occurs on the upper surface of the liner. This ensures the overall molding quality of the lid and improves product yield.

[0009] The limiting structure also includes two second limiting ribs disposed on the cover and extending toward the liner, the two second limiting ribs being located on two opposite sides of the cover opening button.

[0010] This technical solution, by adding a second limiting rib to the cover, further restricts the movement of the opening button along its own rotation axis. Because the cover has a first limiting rib extending upwards and a second limiting rib extending downwards, the first and second limiting ribs work together to limit the full range of movement of the opening button within its working stroke, further improving the limiting effect. The presence of the first limiting rib allows the second limiting rib to be set relatively short, thereby reducing the probability of shrinkage in the area of ​​the cover opposite the second limiting rib during manufacturing and improving product yield.

[0011] The projections of the first limiting rib and the second limiting rib on the horizontal plane at least partially overlap to form a limiting channel between the two first limiting ribs and the two second limiting ribs.

[0012] In this technical solution, the limiting channel formed by the first and second limiting ribs ensures that the lid-opening button swings around its rotation axis within a predetermined range of motion, providing more precise limiting for the button's action. The projections of the first and second limiting ribs on the horizontal plane at least partially overlap to form the limiting channel, optimizing the internal space utilization of the lid. This allows for limiting the swing of the lid-opening button within the limited space between the lid and the liner, making the lid structure more compact without compromising its functionality. Furthermore, the relative positional relationship between the first and second limiting ribs helps to further reduce the height of the second limiting rib, thereby further reducing the probability of shrinkage pits appearing on the outer surface of the lid after molding.

[0013] The cover opening button has an initial state and a trigger state that drives the button plate to rotate. The cover is provided with a clearance hole for a portion of the cover opening button to be exposed. The inner surface of the cover is provided with a guide slope that is connected to the inner periphery of the clearance hole to guide the cover opening button to switch between the trigger state and the initial state.

[0014] In this technical solution, the design of the clearance hole allows a portion of the lid-opening button to be exposed, enabling users to accurately determine the pressing position and perform the lid-opening operation, thus improving ease of use. The guide slope design makes the switch between the triggered and initial states of the lid-opening button smoother, improving the operating feel, and also prevents the lid-opening button from moving back and forth during swinging, ensuring that the rotation axis of the lid-opening button remains in the preset installation position. This avoids the jamming caused by back and forth movement and the resulting operational resistance, thereby achieving smooth lid opening.

[0015] The cover opening button has an initial state and a trigger state that drives the button plate to rotate. The cover has a clearance hole for exposing a portion of the cover opening button. The cover has an inwardly extending reset baffle. The cover opening button has a reset stop edge. In the initial state, the reset stop edge abuts against the reset baffle to prevent the cover opening button from coming out of the clearance hole.

[0016] This technical solution, by setting an inwardly extending reset baffle on the cover, can form a stop and limit the reset edge on the cover opening button, so as to prevent one end of the cover opening button from coming out of the clearance hole when the cover opening button returns from the triggered state to the initial state, thus ensuring the reliability and stability of the cover opening button.

[0017] The inner surface of the cover is provided with transition areas on both sides of the reset baffle. The transition area has a first end connected to the reset baffle and a second end away from the first end. The thickness of the cover gradually increases from the part corresponding to the second end to the part corresponding to the first end.

[0018] This technical solution, by setting transition zones on both sides of the reset baffle and gradually increasing the thickness of the cover, enhances the structural strength of the cover around the clearance hole, helping to disperse and withstand external impacts and reduce the risk of damage. Furthermore, the varying thickness of the cover helps reduce the probability of shrinkage dents appearing at the position corresponding to the reset baffle, improving the yield rate after cover molding. Moreover, when the open button resets to its initial state, the reset edge of the open button impacts the reset baffle. The transition zone design allows the gradually thickening area of ​​the cover to act as a buffer, absorbing and reducing noise and vibration during the impact between the open button and the reset baffle, thus improving the user experience.

[0019] The reset rib extends continuously along the circumferential direction of the clearance hole to form a closed ring structure.

[0020] This technical solution sets the reset baffle in a closed ring shape, which can further strengthen the structural strength of the area adjacent to the clearance hole of the cover, and increase the contact area between the reset baffle and the cover opening button, thereby improving the limiting effect of the reset baffle on the cover opening button.

[0021] The cover is provided with a second limiting rib connected to the reset stop rib and extending toward the liner. There are two second limiting ribs, which are located on two opposite sides of the cover opening button to restrict the movement of the cover opening button along its rotation axis.

[0022] This technical solution, by adding a second limiting rib to the reset stop rib, further restricts the movement of the opening button along its own rotation axis. Since the cover has a first limiting rib extending upwards and a second limiting rib extending downwards, the first and second limiting ribs work together to limit the full range of movement of the opening button within its working stroke, further improving the limiting effect. Furthermore, the second limiting rib is located on the side of the reset stop rib away from the cover, which reduces mold-making costs during cover manufacturing compared to solutions that place a second limiting rib in other locations.

[0023] The cover opening button has a pivot side that is rotatably connected to the cover and a trigger side for triggering the button plate, and the first limiting rib is arranged close to the trigger side.

[0024] The swing amplitude of the trigger side of the cover opening button is larger than that of the pivot side. This technical solution sets the first limiting rib close to the trigger side, which can improve the limiting effect on the swing of the cover opening button, further reduce the probability of the cover opening button shaking along its rotation axis, and enable the cover opening button to switch smoothly between the initial state and the trigger state.

[0025] The cover is also provided with two third limiting ribs that are located on two opposite sides of the button plate and extend from the cover toward the faceplate. The two third limiting ribs cooperate with each other to restrict the movement of the button plate along its rotation axis.

[0026] This technical solution, by adding a third limiting rib to the lid, can limit the button plate and prevent it from moving along its rotation axis. This ensures that the contact area between the button plate and the lid-opening button remains in a preset position, allowing the button plate to respond quickly and open the lid when triggered, avoiding the problem of unresponsive lid opening. Furthermore, because the button plate's movement is restricted, the contact area between the button plate and the pot body also remains in a preset position, ensuring a stable locking state between the lid and the pot body when closed, which facilitates the normal operation of the cooking process.

[0048] like Figure 4 , Figure 5 and Figure 10 As shown, a cooking appliance includes a pot body and a pot lid. The pot lid includes a top cover 2, a liner 1, an opening button 3, and a button plate 4. The button plate 4 is rotatably connected to the liner 1 to lock or unlock with the pot body. The opening button 3 is rotatably connected to the top cover 2 to drive the button plate 4 to rotate. The liner 1 is provided with a limiting structure for restricting the movement of the opening button 3 along its rotation axis. The limiting structure includes two first limiting ribs 11 that are located on two opposite sides of the opening button 3 and extend from the liner 1 toward the top cover 2.

[0049] It should be noted that this application does not limit the specific structural form of the rotatable connection between the lid opening button and the cover. In one embodiment, such as... Figure 8 As shown, the cover 2 has two oppositely arranged supports 26, each support 26 having a shaft hole 261. The shaft hole 261 is a closed design, and the cover opening button 3 has a rotating shaft 32 that matches the shaft hole 261. In another embodiment, the cover has two oppositely arranged supports, each support having a shaft hole with a notch. The cover opening button has a rotating shaft that matches the shaft hole, and the rotating shaft is inserted into the shaft hole through the notch.

[0050] This application provides first limiting ribs 11 extending toward the cover 2 and positioned on opposite sides of the opening button 3 on the liner 1. These two first limiting ribs 11 restrict the movement of the opening button 3 along its rotation axis, ensuring that the contact area between the opening button 3 and the button plate 4 remains in a preset position. This allows the button plate 4 to respond quickly and open the lid when the opening button 3 is triggered, avoiding the problem of unresponsive lid opening. The liner 1 is an internal component, and its upper surface does not constitute part of the outer surface of the lid. Therefore, by providing the first limiting ribs 11 extending toward the cover 2 on the liner 1, even if shrinkage occurs on the upper surface of the liner 1, the shrinkage pits will not be externally exposed, thus ensuring the overall molding quality of the lid and improving product yield.

[0051] The specific structural form of the limiting structure in this application can adopt any of the following embodiments:

[0052] Implementation Method 1: This implementation method is not illustrated. In this implementation method, the height of the first limiting rib on the liner extending toward the cover can match the working stroke of the cover opening button. The full stroke limit of the cover opening button during rotation can be achieved using only the first limiting rib on the liner.

[0053] Implementation Method Two: (e.g.) Figure 4 and Figure 5 As shown, the limiting structure also includes two second limiting ribs 22 provided on the cover 2 and extending toward the liner 1, with the two second limiting ribs 22 standing on two opposite sides of the cover opening button 3.

[0054] This second embodiment, by adding a second limiting rib 22 to the cover 2, further restricts the movement of the opening button 3 along its own rotation axis. Since the liner 1 has a first limiting rib 11 extending upwards and the second limiting rib 22 extending downwards, the first and second limiting ribs cooperate to limit the full range of movement of the opening button 3 within its working stroke, further improving the limiting effect. Because of the presence of the first limiting rib 11, the second limiting rib 22 can be set relatively short, thereby reducing the probability of shrinkage in the part of the cover 2 opposite to the second limiting rib 22 during manufacturing, and improving product yield.

[0055] In this second embodiment, the relative positions of the first limiting rib and the second limiting rib can be any one of the following embodiments:

[0056] Example 1: This example 1 is not illustrated. In this example 1, the first limiting rib and the second limiting rib are arranged in a staggered manner in the horizontal direction.

[0057] In one example, the projection of the first limiting rib in the vertical direction partially overlaps with the projection of the second limiting rib in the vertical direction.

[0058] In another example, the projections of the first and second limiting ribs in the vertical direction do not overlap. For instance, the height of the top surface of the first limiting rib is lower than the height of the bottom surface of the second limiting rib. Alternatively, the height of the top surface of the first limiting rib may be flush with the height of the bottom surface of the second limiting rib.

[0059] Example 2: As Figure 5 As shown, the projections of the first limiting rib 11 and the second limiting rib 22 on the horizontal plane at least partially overlap to form a limiting channel between the two first limiting ribs 11 and the two second limiting ribs 22.

[0060] In this embodiment 2, the limiting channel formed between the first limiting rib 11 and the second limiting rib 22 ensures that the lid opening button 3 swings around its rotation axis within a predetermined range of motion, providing more precise limiting for the action of the lid opening button 3. The projections of the first limiting rib 11 and the second limiting rib 22 on the horizontal plane at least partially overlap to form the limiting channel, which optimizes the space utilization inside the lid. It achieves the swing limiting of the lid opening button 3 within the limited space between the lid 2 and the liner 1, making the lid structure more compact without affecting its functionality. In addition, the relative positional relationship between the first limiting rib 11 and the second limiting rib 22 helps to further reduce the height dimension of the second limiting rib 22, thereby further reducing the probability of shrinkage pits appearing on the surface of the lid 2 after molding.

[0061] The lid opening button 3 has an initial state and a triggered state that drives the button plate 4 to rotate. The cover 2 is provided with a clearance hole 21 for a portion of the lid opening button 3 to be exposed. The design of the clearance hole 21 allows a portion of the lid opening button 3 to be exposed, and the user can accurately know the pressing position through this exposed area to realize the lid opening operation, thus improving the convenience of use.

[0062] To facilitate the assembly of the cover-opening button 3, the shaft 32 of the cover-opening button 3 and the shaft hole 261 of the support 26 are clearance-fitted. Due to machining errors, assembly errors, and deformation during actual transportation and use, the clearance between the shaft 32 of the cover-opening button 3 and the shaft hole 261 of the support 26 may increase. During the swinging process of the cover-opening button 3, the cover-opening button 3 may move in the back-and-forth direction. To avoid this phenomenon, as a preferred embodiment of this application, such as... Figures 1 to 3 , Figure 6 and Figure 7 As shown, the inner surface of the cover 2 is provided with a guide slope 24 that connects to the inner periphery of the clearance hole 21 to guide the opening button 3 to switch between the triggered state and the initial state. The design of the guide slope 24 makes the switching of the opening button 3 between the triggered state and the initial state smoother, improves the operating feel, and prevents the opening button 3 from moving back and forth during the swinging process. This ensures that the rotation axis of the opening button 3 can be kept in the preset installation position, avoiding the jamming caused by back and forth movement and the resulting operational resistance, thus achieving smooth opening of the cover.

[0063] More specifically, the lid opening button 3 is provided with a pressing part 33 that is adapted to the clearance hole 21. When the lid opening button 3 switches between the triggered state and the initial state, the pressing part 33 can abut against the guide slope 24 to slide along the guide slope 24, thereby restricting the movement of the lid opening button 3 in the front-back direction of the pot lid.

[0064] As a preferred embodiment of this application, such as Figure 2 and Figure 3 As shown, the cover 2 has an inwardly extending reset baffle 23, and the open button 3 has a reset stop 31. In the initial state, the reset stop 31 abuts against the reset baffle 23 to prevent the open button 3 from coming out of the clearance hole 21. By providing an inwardly extending reset baffle 23 on the cover 2, a stop and limit can be formed on the reset stop 31 on the open button 3, so as to prevent one end of the open button 3 from coming out of the clearance hole 21 when the open button 3 returns from the triggered state to the initial state, thus ensuring the reliability and stability of the open button 3.

[0065] The setting of the reset baffle 23 makes the wall thickness of the part where the cover 2 is connected to the reset baffle 23 relatively thicker than the rest of the area. During the cooling and molding process after processing, the part of the cover 2 corresponding to the reset baffle 23 may collapse. To avoid this phenomenon, as a preferred embodiment of this method, such as... Figure 3 and Figure 7 As shown, the inner surface of the cover 2 is provided with transition areas 25 on both sides of the reset baffle 23. The transition areas 25 have a first end 251 connected to the reset baffle 23 and a second end 252 away from the first end 251. The thickness of the cover 2 gradually increases from the part corresponding to the second end 252 to the part corresponding to the first end 251. By providing transition areas 25 on both sides of the reset baffle 23 and gradually increasing the thickness of the cover 2, on the one hand, the structural strength of the cover 2 around the clearance hole 21 can be enhanced, which helps to disperse and withstand external impact and reduce the risk of damage. On the other hand, the change in the thickness of the cover 2 helps to reduce the probability of shrinkage pits appearing on the cover 2 at the position corresponding to the reset baffle 23, thereby improving the yield of the cover 2 after molding. Furthermore, when the lid opening button 3 is reset to its initial state, the reset stop edge 31 of the lid opening button 3 will impact the reset stop 23. Through the design of the transition area 25, the gradually thickening area of ​​the cover 2 can act as a buffer zone to absorb and reduce the noise and vibration during the impact between the lid opening button 3 and the reset stop 23, thereby improving the user experience.

[0066] Preferably, the reset baffle 23 is positioned close to the clearance hole 21, and the thickness of the cover 2 corresponding to the transition area 25 between the reset baffle 23 and the clearance hole 21 gradually increases from the part corresponding to the second end 252 to the part corresponding to the first end 251, thereby forming a guide slope 24 on the back of the cover 2 that can be used to guide the opening button 3 to switch between the triggered state and the initial state.

[0067] In this embodiment, the structural design of the reset rib 23 can adopt any one of the following embodiments:

[0068] Example 3: This example 3 is not illustrated. In this example 3, the reset baffle is provided on the back of the cover.

[0069] Example 4: Figure 8 As shown, the reset baffle 23 extends continuously along the circumferential direction of the clearance hole 21 to form a closed ring structure. By setting the reset baffle 23 to a closed ring structure, on the one hand, the structural strength of the area adjacent to the clearance hole 21 of the cover 2 can be further strengthened, and on the other hand, the contact area between the reset baffle 23 and the cover opening button 3 can be increased, thereby improving the limiting effect of the reset baffle 23 on the cover opening button 3.

[0070] As a preferred example under this embodiment 4, such as Figure 8 and Figure 9 As shown, the cover 2 is provided with a second limiting rib 22 connected to the reset stop rib 23 and extending towards the cover 1. There are two second limiting ribs 22, which are located on opposite sides of the cover opening button 3 to restrict the movement of the cover opening button 3 along its rotation axis. By adding the second limiting rib 22 to the reset stop rib 23, the movement of the cover opening button 3 along its own rotation axis can be further restricted. Since the cover 1 is provided with a first limiting rib 11, which extends upward and the second limiting rib 22 extends downward, the first limiting rib 11 and the second limiting rib 22 cooperate with each other to achieve full-stroke movement restriction of the cover opening button 3 within its working stroke range, further improving the limiting effect of the cover opening button 3. Furthermore, the second limiting rib 22 is located on the side of the reset stop rib 23 away from the cover 2. Compared with the technical solution of setting the second limiting rib 22 in other positions, this example can reduce the mold opening cost in the manufacturing process of the cover 2.

[0071] The cover opening button 3 has a pivot side that is rotatably connected to the cover 2, and a trigger side for triggering the button plate 4. This application does not limit the specific location of the first limiting rib 11, which can be any of the following embodiments:

[0072] Implementation Method 3: This implementation method 3 is not illustrated. In this implementation method 3, the first limiting rib is set near the rotating shaft side.

[0073] Implementation Method 4: This implementation method 4 is not illustrated. In this implementation method 4, the first limiting rib is located at the middle position between the rotating shaft side and the trigger side.

[0074] Implementation Method 5: (e.g.) Figure 4 and Figure 5 As shown, the first limiting rib 11 is arranged close to the trigger side. The swing amplitude of the trigger side of the cover opening button 3 is larger than that of the swing amplitude of the rotating shaft side. This technical solution sets the first limiting rib 11 close to the trigger side, which can improve the limiting effect on the swing of the cover opening button 3, further reduce the probability of the cover opening button 3 shaking along its rotation axis, and enable the cover opening button 3 to switch smoothly between the initial state and the trigger state.

[0075] Furthermore, such as Figure 10 As shown, in order to reduce the probability of deformation of the first limiting rib 11, the cover 1 is also provided with a first reinforcing rib 13 connected to the first limiting rib 11.

[0076] As a preferred embodiment of this application, such as Figure 4 and Figure 5 As shown, the cover 1 is also provided with two third limiting ribs 12, which are located on opposite sides of the button plate 4 and extend from the cover 1 toward the top cover 2. The two third limiting ribs 12 cooperate with each other to restrict the movement of the button plate 4 along its rotation axis. By adding the third limiting ribs 12 to the cover 1, the button plate 4 can be limited, preventing it from moving along its rotation axis. This ensures that the contact part between the button plate 4 and the lid opening button 3 remains in a preset position, so that when the lid opening button 3 is triggered, the button plate 4 can respond quickly to open the lid, avoiding the problem of unresponsive lid opening. On the other hand, because the movement position of the button plate 4 is restricted, it also ensures that the contact part between the button plate 4 and the pot body can remain in a preset position, so that the lid and the pot body can maintain a stable locking state when the lid is closed, which helps the cooking process to proceed normally.

[0077] Furthermore, such as Figure 10 As shown, in order to reduce the probability of deformation of the third limiting rib 12, the liner 1 is also provided with a second reinforcing rib 14 connected to the third limiting rib 12.
