Cooking utensil

Abstract

The cooking utensil comprises an outer cover and an operation panel assembly, the outer cover is provided with an installation opening, the operation panel assembly comprises a panel support and a circuit board arranged on the panel support, the panel support is provided with a buckle, and the outer cover is provided with a clamping jaw folded inwards at the installation opening. The clamping jaw comprises a connecting section connected with the outer wall face of the outer cover and a bent section which is connected with the connecting section and folded towards the interior of the installation opening relative to the connecting section, and the bent section abuts against the buckle so that the panel support can be clamped and fixed to the outer cover. Due to the fact that the bent section is not directly connected with the outer wall face of the outer cover, even if the bent section is stressed to deflect, the probability that the connecting position of the outer wall face of the outer cover and the connecting section is curled and deformed can be reduced through the buffering effect of the connecting section. When the panel support is installed, the angle between the bent section and the matching surface of the buckle is closer to 90 degrees when the bent section deflects and deforms outwards, so that the matching clearance between the bent section and the buckle is smaller, the installation reliability of the panel support is guaranteed, and the risk of unhooking is reduced.

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, pressure cookers, or slow cookers, generally include a pot body and a lid. The pot body includes an outer cover, a heat preservation cover built into the outer cover, and an inner pot built into the heat preservation cover. To facilitate user operation of the cooking appliance, an operation panel assembly is also provided on the pot body, and the outer cover has an installation port that is compatible with the operation panel assembly.

[0003] Most existing covers are thin-walled metal structures. The control panel assembly includes a panel bracket and a circuit board mounted on the panel bracket. The panel bracket is made of plastic. In order to improve the assembly efficiency of the panel bracket and the cover, the panel bracket is fixed to the mounting opening of the cover by a snap-fit ​​method. Specifically, the outer cover has inwardly folding claws along the circumference of the mounting opening, and the panel bracket is equipped with buckles that can engage with the claws. The existing claws on the outer cover are flat, plate-shaped hooks extending straight towards the insulation cover side. During assembly, the panel bracket is pushed from the outside of the outer cover along the inside of the mounting opening from front to back. The buckles on the panel bracket will press the plate-shaped hooks on the outer cover to bend towards the side opposite to the axis of the mounting opening until the buckles on the panel bracket are squeezed into the rear side of the plate-shaped hooks. After the buckles move to the preset installation position, the plate-shaped hooks will spring back. However, the plate-shaped hooks are initially flat. During installation, the plate-shaped hooks are subjected to force and bend away from the axis of the mounting opening. This will cause the fit gap between the plate-shaped hooks and the buckles to be inconsistent with the design after the hooks spring back, and the engagement cannot be maintained stably. If the panel bracket is tilted to one side during installation, causing excessive stress on some of the sheet hooks, this can lead to over-bending of those hooks. This over-bending can cause the following problems: Because the outer cover is a thin-walled metal structure, the sheet hooks are directly connected to the outer surface of the cover and extend in a straight line. Therefore, when these sheet hooks are compressed and excessively bent, the sheet hooks and the outer surface of the cover bend together, causing curling and deformation at the joint between the sheet hooks and the outer surface of the cover. This not only affects the appearance but also reduces the fit between the panel bracket and the mounting opening of the cover after installation. External impurities, oil, and water can easily enter the gap between them and then into the pot, affecting the lifespan of the internal components. Furthermore, excessive bending of the sheet hooks can cause the edges to fold outside the mating surface with the latch, leading to latch disengagement and assembly failure. This can result in the control panel becoming loose during use and failing drop tests. Utility Model Content

[0004] This application provides a cooking appliance to solve the technical problems of poor stability and easy loosening of the control panel assembly after installation in existing cooking appliances, and the easy deformation of the outer facade of the outer casing during the installation process.

[0005] The technical solution adopted in this application is as follows:

[0006] A cooking appliance includes an outer cover and a control panel assembly. The outer cover has a mounting opening. The control panel assembly includes a panel support and a circuit board disposed on the panel support. The panel support has a buckle. The outer cover has an inwardly folding claw at the mounting opening. The claw includes a connecting section connected to the outer wall surface of the outer cover and a bent section connected to the connecting section and folded inward relative to the connecting section toward the mounting opening. The bent section abuts against the buckle to snap and fix the panel support to the outer cover.

[0007] In this application, the latches on the outer cover include a connecting section directly connected to the outer wall of the outer cover and a bent section connected to the connecting section and folded inward relative to the connecting section toward the mounting opening. That is, the bent section is indirectly connected to the outer wall of the outer cover. In its initial state (before the panel bracket is installed), the bent section is bent toward the side closest to the mounting opening axis. During the assembly of the panel bracket to the outer cover, the bent section is pushed by the latches on the panel bracket and deflects toward the side away from the mounting opening axis. Because the bent section is not directly connected to the outer wall of the outer cover, even if the bent section deflects under force... The deflection is not directly transmitted to the outer wall of the cover, but to the connecting section. The stress is dispersed through the buffering effect of the connecting section, which greatly reduces the probability of curling and deformation at the connection between the outer wall of the cover and the connecting section. This not only effectively ensures the appearance quality of the outer wall of the cover, but also helps to ensure that the mounting opening does not deform. This ensures the fit between the panel bracket and the inner periphery of the mounting opening after the panel bracket is installed, reducing the probability of external impurities entering the cooking appliance through the gap between the panel bracket and the inner periphery of the mounting opening, and providing a good protective effect for the internal components of the cooking appliance.

[0008] Moreover, the bent section itself has already undergone pre-deformation and has creases in its initial state. During the process of assembling the panel bracket to the outer cover, the bent section is pushed by the buckle on the panel bracket and deflects away from the axis of the installation opening. The more the bent section deflects outward, the closer the angle between it and the buckle mating surface will be to 90°. This makes the mating gap between the bent section and the buckle smaller, until it becomes zero. Therefore, the mating gap between the two can be guaranteed to be below a certain design amount, ensuring the reliability of the panel bracket installation and reducing the risk of disengagement.

[0009] The buckle includes a cantilever portion connected to the panel bracket and a limiting portion connected to the cantilever portion. The panel bracket, the cantilever portion, and the limiting portion form a slot for the bent section to be inserted. The limiting portion includes an inner surface that forms part of the inner wall of the slot and an outer surface connected to the inner surface. The outer surface is not lower than the height of the end of the bent section when it is bent outward toward the mounting opening to its limit position.

[0010] In this technical solution, the limit position of the bending section's outward folding deformation toward the mounting opening is the position of the bending section when the panel bracket is pushed inward and the panel bracket's buckle is about to disengage from the outward pressing of the bending section. By limiting the outer surface of the limiting part to a height no lower than the position of the end of the bending section when it folds outward toward the mounting opening to its limit position, when the bending section is subjected to force and deflects away from the axis of the mounting opening during installation, the buckle will not push the bending section further away from the axis of the mounting opening along the horizontal direction of the connecting section. This further ensures the assembly gap between the bendable section and the buckle, avoiding the occurrence of disengagement.

[0011] The outer surface extends at an angle to the side opposite to the slot to form a guide slope.

[0012] In this technical solution, the guide slope can guide the panel bracket during installation. Furthermore, during the pushing process from the outside of the outer cover to the back, the guide slope ensures that most of the direct contact area with the bent section is part of the guide slope, achieving surface-to-surface contact during the pushing process. This makes the pushing of the bent section by the buckle more gentle, avoiding secondary bending deformation caused by excessive local stress in the bent section due to a small contact area. This allows the bent section to fold outwards along the pre-deformation position and spring back along the pre-deformation position when the pushing force disappears, further ensuring the assembly gap between the bent section and the buckle, and achieving stable installation of the panel bracket.

[0013] The buckle includes a cantilever portion connected to the panel bracket and a limiting portion connected to the cantilever portion. The panel bracket, the cantilever portion and the limiting portion form a slot for the bent section to be inserted. The panel bracket has a relief portion on the side near the slot opening to avoid the bent section.

[0014] In this technical solution, by setting a clearance part to avoid the bending section on the side of the panel bracket near the slot opening, interference with the bending section can be avoided during the springback process of the bending section, providing favorable conditions for a suitable assembly gap between the bending section and the limiting part after assembly.

[0015] The clearance portion is a chamfered structure provided on the panel support.

[0016] In this technical solution, the clearance part is set as a chamfered structure. On the one hand, it facilitates the processing and manufacturing of the panel bracket, facilitates demolding during the manufacturing process, and improves the manufacturing quality of the panel bracket. On the other hand, the chamfered structure can provide sufficient deformation space for the bending section within a limited space, further reducing the probability of interference between the bending section and the panel bracket during the springback deformation process.

[0017] The outer cover is also provided with several inwardly folded anti-deformation parts at the mounting opening. The anti-deformation parts include flanged parts, which abut against the panel bracket along the circumference of the mounting opening.

[0018] In this technical solution, several inwardly folded anti-deformation parts are provided at the mounting opening, which can improve the structural strength of the outer cover at the mounting opening and reduce the probability of deformation of the outer cover around the mounting opening under external force. The folded part abuts against the panel bracket along the circumference of the mounting opening, which can provide guidance during the assembly of the panel bracket and limit the panel bracket along the circumference of the mounting opening after installation, ensuring the fit between the panel bracket and the inner circumference of the mounting opening and preventing the panel bracket from tilting.

[0019] At least a portion of the anti-deformation part and the claw are alternately arranged along the circumference of the mounting opening.

[0020] In this technical solution, at least some of the anti-deformation parts and the claws are alternately distributed along the circumference of the mounting opening, which can generate more uniform limiting and force on the panel bracket, making the force on the panel bracket and the bending section more uniform during the assembly process, reducing the phenomenon of local stress concentration, and improving assembly efficiency.

[0021] The flange of the adjacent anti-deformation part is at least partially connected to the connecting section of the claw, and there is a deformation gap between the bending section and the flange.

[0022] In this technical solution, the flanged portion of the anti-deformation part is at least partially connected to the connecting section of the claw. This improves the structural strength of the flanged portion and the connecting section. In particular, the flanged portion can be used to pull the connecting section. This design allows the flanged portion to pull the connecting section in the opposite direction during panel bracket installation, significantly reducing the probability of deformation of the connecting section. This avoids the tensile force of the bending section being transmitted to the outer wall of the outer casing through the connecting section, effectively preventing deformation of the outer wall of the outer casing and ensuring the appearance quality of the outer wall of the outer casing and the fit between the panel bracket and the inner periphery of the mounting opening after installation. A deformation notch exists between the bending section and the flanged portion, allowing the bending section to fold outwards and spring back inwards relative to the flanged portion and the connecting section, providing deformation space for the bending section and facilitating the assembly of the panel bracket.

[0023] The anti-deformation part also includes a stop part disposed on the outer wall surface of the flange part away from the outer cover, and the panel bracket abuts against the stop part to limit the inward displacement of the panel bracket along the mounting opening.

[0024] In this technical solution, a stop is provided on the side of the flange that is away from the outer wall of the cover. This can further enhance the structural strength of the anti-deformation part. During the assembly of the panel bracket, the stop can be used to pull the flange to reduce the probability of deformation. Moreover, the stop can abut against the panel bracket to limit the inward movement of the panel bracket along the mounting opening. This avoids the probability of the panel bracket moving inward under the action of external touching, pressing, etc. during use, thus ensuring the stability of the panel bracket installation and the reliability of its use.

[0025] The angle at which the bent section folds inward toward the mounting opening is less than or equal to 90°.

[0026] In this technical solution, the bending angle of the bending section is less than or equal to 90°, which can reduce stress concentration in the bending section during the bending process, reduce the risk of bending section breakage, and also help reduce resistance during panel bracket installation and improve panel bracket assembly efficiency.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0043] like Figures 1 to 4 As shown, a cooking appliance includes an outer cover 1 and an operation panel assembly. The outer cover 1 has an installation opening 11. The operation panel assembly includes a panel support 2 and a circuit board 3 disposed on the panel support 2. The panel support 2 has a buckle. The outer cover 1 has an inwardly folding claw at the installation opening 11. The claw includes a connecting section 12 connected to the outer wall surface of the outer cover 1 and a bent section 13 connected to the connecting section 12 and folded inward relative to the connecting section 12 toward the installation opening 11. The bent section 13 abuts against the buckle to snap and fix the panel support 2 to the outer cover 1.

[0044] Preferably, the connecting segment 12 in this application is a structure that is connected to the outer wall surface of the outer cover 1 and extends straight toward the inner side of the outer cover 1.

[0045] The bending segment 13 is connected to the connecting segment 12 and folds inward toward the mounting opening 11, meaning that the bending segment 13 folds toward the side closer to the axis of the mounting opening 11. In this application, the bending segment 13 has undergone pre-deformation treatment, which gives the bending segment 13 a tendency to fold inward toward the mounting opening 11.

[0046] In this application, the latch provided on the outer cover 1 includes a connecting section 12 directly connected to the outer wall surface of the outer cover 1 and a bent section 13 connected to the connecting section 12 and folded inward toward the mounting opening 11 relative to the connecting section 12. That is, the bent section 13 is indirectly connected to the outer wall surface of the outer cover 1, and the bent section 13 is bent toward the side closer to the axis of the mounting opening 11 in the initial state (i.e., before the panel bracket 2 is installed). During the process of assembling the panel bracket 2 to the outer cover 1, the bent section 13 is pushed by the latch on the panel bracket 2 and deflects toward the side away from the axis of the mounting opening 11. Because the bent section 13 is not directly connected to the outer wall surface of the outer cover 1, even if the bent section 13 is bent inward, the latch is not directly connected to the outer wall surface of the outer cover 1. 3. When the force is deflected, it will not be directly transmitted to the outer wall of the outer cover 1, but to the connecting section 12. The corresponding stress is dispersed through the buffering effect of the connecting section 12, which can greatly reduce the probability of curling and deformation at the connection position between the outer wall of the outer cover 1 and the connecting section 12. This not only effectively ensures the appearance quality of the outer wall of the outer cover 1, but also helps to ensure that the mounting opening 11 does not deform. This ensures the fit between the panel bracket 2 and the inner periphery of the mounting opening 11 after the panel bracket 2 is installed, reducing the probability of external impurities entering the interior of the cooking appliance through the gap between the panel bracket 2 and the inner periphery of the mounting opening 11, and providing a good protective effect for the internal components of the cooking appliance.

[0047] Moreover, the bent section 13 itself has been pre-deformed in its initial state, with creases. During the process of assembling the panel bracket 2 to the outer cover 1, the bent section 13 is pushed by the buckle on the panel bracket 2 and deflects towards the side away from the axis of the mounting opening 11. The more the bent section 13 deflects outward, the closer the angle between it and the buckle mating surface will be to 90°. This makes the mating gap between the bent section 13 and the buckle smaller, until it becomes zero. Therefore, the mating gap between the two can be guaranteed to be below a certain design amount, ensuring the reliability of the installation of the panel bracket 2 and reducing the risk of disengagement.

[0048] like Figure 2 and Figure 5 As shown, an example of a generally rectangular mounting opening 11 is given. However, this application is not limited to this; the mounting opening 11 may also be elliptical, fan-shaped, or similar in shape.

[0049] Preferably, the outer cover 1 is provided with a number of claws at intervals along the circumference of the mounting opening 11, and the panel bracket 2 is provided with a number of buckles along its circumference to achieve a stable installation of the panel bracket 2.

[0050] As a preferred embodiment of this application, such as Figure 2As shown, the buckle includes a cantilever portion 21 connected to the panel bracket 2 and a limiting portion 22 connected to the cantilever portion 21. The panel bracket 2, the cantilever portion 21 and the limiting portion 22 form a slot 23 for the insertion of the bent section 13. The limiting portion 22 includes an inner surface 221 that forms part of the inner wall of the slot 23 and an outer surface 222 connected to the inner surface 221. The outer surface 222 is not lower than the height of the end of the bent section 13 when it is bent outward toward the mounting opening 11 to the limit position. In this embodiment, the extreme position of the bending segment 13 folding outward toward the mounting opening 11 is the position of the bending segment 13 when the panel bracket 2 is pushed inward and the buckle of the panel bracket 2 is about to disengage from the outward pressure on the bending segment 13. By limiting the outer surface 222 of the limiting part 22 to a height not lower than the position of the end of the bending segment 13 when it folds outward toward the mounting opening 11 to the extreme position, when the bending segment 13 is subjected to force and deflects in a direction away from the axis of the mounting opening 11 during installation, the buckle will not push the bending segment 13 further away from the axis of the mounting opening 11 along the horizontal direction where the connecting segment 12 is located. When the buckle moves to the rear of the bending segment 13 and moves toward the bending segment 13, the buckle's abutment against the bending segment 13 will cause the bending segment 13 to spring back further inward, thereby further ensuring the assembly gap between the bendable segment 13 and the buckle and avoiding the occurrence of disengagement.

[0051] As a preferred embodiment of this implementation, such as Figure 2 As shown, the outer surface 222 extends obliquely on the side facing away from the slot 23 to form a guide slope 223. In this embodiment, the guide slope 223 can guide the panel bracket 2 during installation. During the pushing process of the panel bracket 2 from the outside of the outer cover 1 from front to back, it can ensure that most of the direct contact part that pushes the bent section 13 is the guide slope 223, realizing the surface-to-surface cooperation and abutment during the pushing process. This makes the pushing of the buckle on the bent section 13 more gentle during the pushing process, avoiding secondary bending deformation caused by excessive local stress in the bent section 13 due to the small contact area. This allows the bent section 13 to fold outward along the pre-deformation position, and when the pushing force disappears, the bent section 13 can rebound along the pre-deformation position, further ensuring the assembly gap between the bent section 13 and the buckle, and realizing the stable installation of the panel bracket 2.

[0052] Furthermore, such as Figure 2 As shown, the outer surface 222 and the guide slope 223 are connected by an arc-shaped transition surface to achieve a smooth transition between the outer surface 222 and the guide slope 223, avoiding sharp corners between the outer surface 222 and the guide slope 223. This prevents the bent section 13 from being pressed by sharp corners and bending from the pressing position during the assembly of the panel bracket 2.

[0053] As a preferred embodiment of this application, such as Figure 2 As shown, the buckle includes a cantilever portion 21 connected to the panel bracket 2 and a limiting portion 22 connected to the cantilever portion 21. The panel bracket 2, the cantilever portion 21, and the limiting portion 22 form a slot 23 for the insertion of the bent section 13. The panel bracket 2 has a clearance portion on the side near the opening of the slot 23 to avoid interference with the bent section 13. In this embodiment, by providing a clearance portion on the side of the panel bracket 2 near the opening of the slot 23 to avoid interference with the bent section 13 during its rebound, favorable conditions are provided for a suitable assembly gap between the bent section 13 and the limiting portion 22 after assembly.

[0054] As a preferred embodiment of this implementation, such as Figure 2 As shown, the clearance portion is a chamfered structure 24 provided on the panel support 2. Setting the clearance portion as a chamfered structure 24 facilitates the processing and manufacturing of the panel support 2, making demolding easier and improving the manufacturing quality of the panel support 2. Furthermore, the chamfered structure 24 provides sufficient deformation space for the bending segment 13 within a limited space, further reducing the probability of interference between the bending segment 13 and the panel support 2 during springback deformation. The chamfered structure 24 can be a 45° chamfer or a rounded chamfer recessed towards the side away from the bending segment 13; no limitation is made here.

[0055] As a preferred embodiment of this application, such as Figure 5 and Figure 6 As shown, the outer cover 1 is further provided with several inwardly folded anti-deformation parts at the mounting opening 11. These anti-deformation parts include flanges 14, which abut against the panel support 2 along the circumference of the mounting opening 11. Preferably, multiple anti-deformation parts are provided along the circumference of the mounting opening 11. In this embodiment, providing several inwardly folded anti-deformation parts at the mounting opening 11 can improve the structural strength of the outer cover 1 at the mounting opening 11 and reduce the probability of deformation of the outer cover 1 around the mounting opening 11 under external force. The flanges 14 abut against the panel support 2 along the circumference of the mounting opening 11, providing guidance during the assembly of the panel support 2 and limiting the panel support 2 along the circumference of the mounting opening 11 after installation, ensuring the fit between the panel support 2 and the inner periphery of the mounting opening 11 and preventing the panel support 2 from tilting.

[0056] Preferably, the flange 14 extends straight along the mounting opening 11 toward the inner side of the outer cover 1. This design can avoid stress concentration at the connection between the flange 14 and the outer wall of the outer cover 1 due to bending, further ensuring the appearance quality of the outer wall of the outer cover 1. It also helps the panel bracket 2 to fit snugly against the inner periphery of the mounting opening 11 after assembly, reducing the gap size.

[0057] As a preferred embodiment of this implementation, such as Figure 5 As shown, at least some of the anti-deformation parts and the claws are alternately arranged along the circumference of the mounting opening 11. In this embodiment, the alternating distribution of at least some of the anti-deformation parts and the claws along the circumference of the mounting opening 11 can generate more uniform limiting and force on the panel support 2, making the force on the panel support 2 and the bending section 13 more uniform during the assembly process, reducing the phenomenon of local stress concentration, and improving assembly efficiency.

[0058] Furthermore, such as Figure 6 As shown, the flanged portion 14 of the adjacent anti-deformation part is at least partially connected to the connecting section 12 of the claw, and there is a deformation gap 16 between the bending section 13 and the flanged portion 14. Connecting the flanged portion 14 of the anti-deformation part to the connecting section 12 of the claw at least partially can improve the structural strength of the flanged portion 14 and the connecting section 12. In particular, the flanged portion 14 can be used to pull the connecting section 12. With this arrangement, when the bending section 13 is subjected to force and folds outward during the installation of the panel bracket 2, and pulls the connecting section 12, the flanged portion 14 can pull the connecting section 12 in the opposite direction, which greatly reduces the probability of deformation of the connecting section 12. This avoids the tension of the bending section 13 being transmitted to the outer wall of the outer cover 1 through the connecting section 12, effectively preventing the deformation of the outer wall of the outer cover 1, ensuring the appearance quality of the outer wall of the outer cover 1 and the fit between the panel bracket 2 and the inner periphery of the mounting opening 11 after installation. There is a deformation notch 16 between the bent section 13 and the flange 14, which allows the bent section 13 to fold outward and spring back inward relative to the flange 14 and the connecting section 12, providing deformation space for the bent section 13 and facilitating the assembly of the panel bracket 2.

[0059] As a preferred embodiment of this implementation, such as Figure 5 and Figure 6 As shown, the anti-deformation part also includes a stop 15 disposed on the side of the flange 14 away from the outer wall surface of the outer cover 1. The panel bracket 2 abuts against the stop 15 to limit the inward displacement of the panel bracket 2 along the mounting opening 11. The stop 15, disposed on the side of the flange 14 away from the outer wall surface of the outer cover 1, further enhances the structural strength of the anti-deformation part. During the assembly of the panel bracket 2, the pulling effect of the stop 15 on the flange 14 reduces the probability of deformation of the flange 14. Furthermore, the stop 15 abuts against the panel bracket 2 to limit the inward displacement of the panel bracket 2 along the mounting opening 11, thereby preventing the panel bracket 2 from moving inward under external touch, pressure, or other forces during use, ensuring the stability of the panel bracket 2 installation and the reliability of its use.

[0060] As a preferred embodiment of this application, such as Figure 2As shown, the angle at which the bent section 13 is folded inward toward the mounting opening 11 is less than or equal to 90°. This setting can reduce stress concentration in the bent section 13 during the bending process, reduce the risk of breakage of the bent section 13, and also help reduce the resistance during the installation of the panel bracket 2, thereby improving the assembly efficiency of the panel bracket 2.

[0061] As a preferred embodiment of this application, such as Figure 5 As shown, the panel bracket 2 is provided with a mounting position for mounting the circuit board 3. The circuit board 3 is fixedly mounted on the panel bracket 2 to form an operation panel assembly. After the two are assembled, the operation panel assembly is then assembled into the mounting port 11 of the outer cover 1, which improves the assembly efficiency.
