Detailed implementation manners

[0033] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] Currently, with the development of technology and the improvement of people's living standards, more and more cooking appliances have emerged in the kitchen to meet different cooking needs and preferences. These appliances not only improve cooking efficiency but also enrich the taste and nutrition of food.

[0035] There are various types of cooking appliances, including rice cookers, pressure cookers, electric stew pots, etc. Taking the rice cooker as an example, an electric rice cooker is a modern cooking utensil that can perform various processes such as steaming, boiling, stewing, simmering, and braising. It can not only cook food thoroughly but also keep it warm. It is clean, hygienic, pollution-free, time-saving, and labor-saving, and is one of the indispensable utensils for modern household chores.

[0036] As an efficient and multifunctional cooking tool, the rice cooker has penetrated into the daily lives of thousands of households. With its simple operation and automated cooking process, it greatly facilitates people's lives. However, the traditional ways of opening the lid of a rice cooker usually use embedded push buttons, and these designs may cause inconvenience to users in some cases. For example, embedded push buttons may require users to apply relatively large local pressure with their fingertips, and long-term use may cause hand fatigue or discomfort. In addition, in the case of wet hands or wearing gloves, these ways of opening the lid may also become less easy to operate.

[0037] Based on this, the embodiments of the present application provide a cooking appliance, aiming to improve the problem that the opening and closing of the cooking appliance in the related art are not simple enough.

[0038] In the embodiments of the present application, the cooking appliance may include one of a pressure cooker, a rice cooker, an electric stew pot, a soymilk machine, and a juicer. The specific type of the cooking appliance is not limited in this embodiment. For the convenience of elaborating the following content, the cooking appliance in the following embodiments is a rice cooker, and the advantages of the cooking appliance of the present application being convenient for opening and closing the lid are introduced in detail.

[0039] Please refer to Figures 1 to 3 , the cooking appliance 100 in the embodiments of the present application includes a housing cover 10 and an upper lid 20. Taking the rice cooker as an example, the housing cover 10 is an important part of the rice cooker. It and the inner pot 40 (that is, the inner liner or the pot body of the rice cooker) together constitute the basic structure of the rice cooker. The inner pot 40 is the part in the rice cooker that directly contacts the food and is usually made of a material with good thermal conductivity, such as aluminum alloy or stainless steel. The housing cover 10 is usually used as the outer structure of the rice cooker, playing a role in protecting the internal electronic components and the heating system, that is, providing a strong housing to protect the internal structure from external impacts and damages. The housing cover 10 also helps to maintain the overall appearance of the rice cooker. Among them, the housing cover 10 is usually made of a durable and insulating material, such as plastic, metal, or a metal-plastic composite material.

[0040] The upper lid 20 is disposed on the housing cover 10 in an openable and closable manner. During the cooking process, the upper lid 20 and the inner pot 40 can be tightly combined to form a sealed environment, which helps to keep the moisture and flavor of the food. And the upper lid 20 can be firmly closed on the housing cover 10 to prevent food from splashing out and protect the safety of the user. After cooking is completed, opening the upper lid 20 can help the inside of the rice cooker to dissipate heat quickly and reduce the temperature of the food; it can also facilitate the user to clean the inside of the cooking appliance 100 subsequently, including components such as the upper lid 20 and the inner pot 40.

[0041] The cooking appliance 100 further includes a locking component 30. The locking component 30 is responsible for controlling the locking and unlocking between the upper lid 20 and the housing cover 10, ensuring that the upper lid 20 can be safely opened and closed, and preventing the upper lid 20 from being accidentally opened due to steam pressure or other external forces, thereby protecting the user from scalding or steam burns.

[0042] Specifically, the locking component 30 includes a sliding button 31, a clamping plate 32, and a lock 33. The sliding button 31 and the clamping plate 32 are both disposed on one of the housing cover 10 and the upper lid 20, and the lock 33 is disposed on the other of the housing cover 10 and the upper lid 20, providing flexibility in design and enabling the specific positions of the sliding button 31, the clamping plate 32, and the lock 33 to be set according to the specific requirements of the product or the user's operating habits.

[0043] Furthermore, the buckle plate 32 is configured to be rotatable relative to the outer shell 10 or the upper cover 20 where it is located, the sliding button 31 is configured to be slidable along the outer surface of the outer shell 10 or the upper cover 20 where it is located, the locking buckle 33 is located on the rotation path of the buckle plate 32 and is used for snap-fitting with the buckle plate 32. The snap-fitting of the buckle plate 32 and the locking buckle 33 ensures the firmness when the upper cover 20 is closed, prevents the accidental opening of the upper cover 20 due to pressure or other external forces during cooking, and improves the use safety.

[0044] When opening the cover, the user slides the sliding button 31 provided on the outer surface of the outer shell 10 or the upper cover 20, so that the sliding button 31 is in the sliding stroke. The sliding button 31 can drive the buckle plate 32 to rotate away from the locking buckle 33 to release the snap-fitting state and achieve opening the cover. The way of opening the cover is intuitive and easy to operate. The user can use the palm or finger to slide, and the user only needs to perform a single sliding operation to complete opening the cover, which improves the convenience of use.

[0045] The sliding button 31 can be cleverly arranged on the outer surface of the outer shell 10 or the upper cover 20 of the rice cooker, and the sliding direction can be set according to the actual shape of the outer surface of the outer shell 10 or the upper cover 20, such as horizontal, vertical or inclined. That is, this embodiment can set multiple cover-opening directions according to the outer surface of the upper cover 20 or the outer shell 10, such as sliding to open the cover in the up-down direction, sliding to open the cover in the horizontal direction or sliding to open the cover in the inclined direction, and can adapt to rice cookers of different shapes and sizes, with high flexibility and adaptability.

[0046] Exemplarily, the sliding button 31 and the buckle plate 32 are arranged on the outer shell 10, and the sliding button 31 is configured to perform vertical movement within a set stroke relative to the outer shell 10. The locking buckle 33 is arranged on the upper cover 20. The user can drive the buckle plate 32 to rotate relative to the outer shell 10 by sliding the sliding button 31 in the up-down direction. When the sliding button 31 moves downward, the sliding button 31 is in sliding contact with the buckle plate 32, and the buckle plate 32 is squeezed by the sliding button 31 and rotates away from the locking buckle 33, so that the buckle plate 32 and the locking buckle 33 are released from the snap-fitting state, and the cover can be opened. Affected by the set stroke, the sliding button 31 cannot continue to slide downward. To realize the automatic reset of the buckle plate 32 after opening the cover, the self-weight of the buckle plate 32 can be adjusted so that the weights at the vertical two ends of the buckle plate 32 are inconsistent, and the lower end is heavier. After the external force on the sliding button 31 is lost, due to the larger weight at the lower end of the buckle plate 32, it rotates by itself towards the end with larger weight and keeps in the vertical state. During the rotation of the buckle plate 32, it pushes against the sliding button 31 to slide upward and reset, preparing for the next cover opening, reducing the need for manual operation.

[0047] In some embodiments, the upper cover 20 and the outer housing 10 can be separated and closed, which can be achieved by setting two sets of locking components 30. The two sets of locking components 30 are arranged oppositely. Exemplarily, the sliding buttons 31 and the buckling plates 32 are arranged on the upper cover 20, and the sliding buttons 31 are configured to move vertically within a set stroke relative to the upper cover 20. The locking catches 33 are arranged on the outer housing 10. The user can drive the buckling plates 32 to rotate relative to the upper cover 20 by sliding the sliding buttons 31 on both sides in the up and down directions with both hands. When the sliding buttons 31 move upward, the sliding buttons 31 are in sliding contact with the buckling plates 32, and the buckling plates 32 are squeezed by the sliding buttons 31 and rotate away from the locking catches 33, so that the buckling plates 32 are disengaged from the locking catches 33, and the opening of the cover can be realized.

[0048] Alternatively, as Figure 4 and Figure 5 shown, one side of the upper cover 20 can also be realized by the clamping and cooperation of the locking component 30, and the other side can be realized by the form that the upper cover 20 is hinged to the outer housing 10. After the user slides the sliding button 31, the upper cover 20 is lifted and rotated relative to the outer housing 10 to open the upper cover 20.

[0049] In this embodiment, to realize the semi-automatic opening of the cover, a hinge shaft 21 can be arranged on the side of the upper cover 20 away from the locking component 30. The hinge shaft 21 is specifically inserted into the hinge hole 22 of the upper cover 20. The cooking appliance 100 further includes a hinge spring 70 sleeved on the hinge shaft 21. The hinge spring 70 has a first spring arm 71 and a second spring arm 72. The first spring arm 71 is used to connect with the outer housing 10, and the second spring arm 72 extends along the direction towards the locking component 30 and is connected with the upper cover 20. The extension of the second spring arm 72 ensures that the elastic force is transmitted in a specific direction, which helps to more effectively control the opening and closing actions of the upper cover 20. After the clamping on one side of the upper cover 20 is released, the other side is automatically flipped open by the elastic force of the hinge spring 70. The user only needs to slide the sliding button 31 on one side to trigger the opening action of the cover, without manually lifting the upper cover 20, which simplifies the operation process.

[0050] Among them, two fixing holes 11b (as Figure 1 shown) are provided at the position of the outer housing 10 corresponding to the hinge shaft 21. The two ends of the hinge shaft 21 are respectively fixed in the two fixing holes 11b. The fixing holes 11b can enhance the structural strength of the outer housing 10 in the area of the hinge shaft 21 and resist the stress generated by frequently opening and closing the upper cover 20. Improve the stability of the connection between the upper cover 20 and the outer housing 10, reduce the shaking during the flipping process of the upper cover 20, and provide a more stable use experience.

[0051] Furthermore, a hinge support leg 23 is arranged on the upper end surface of the inner cover. The end of the second spring arm 72 far from the hinge shaft 21 is limited in the hinge support leg 23. The hinge support leg 23 provides a stable support point for the second spring arm 72 and enhances the stability of the connection between the hinge spring 70 and the inner cover.

[0052] There are two hinge springs 70. The two hinge springs 70 are symmetrically sleeved on the hinge shaft 21. Two hinge feet 23 are correspondingly arranged on the inner cover. The second spring arms 72 of the two hinge springs 70 are respectively limited in the two hinge feet 23. The two hinge springs 70 can provide stronger elastic force, making it easier for the upper cover 20 to automatically flip after the buckle assembly 30 releases the clamped state, making the opening operation smoother and providing a better user experience.

[0053] As Figure 6 shown, in some embodiments, the outer shell cover 10 includes a cover body 11 and a guiding portion 12 connected to the cover body 11. The cover body 11 plays a protective role and can prevent internal components from being invaded by dust, moisture or other potential damages. The guiding portion 12 is used to ensure that the sliding button 31 slides along a specific direction and prevent the sliding button 31 from deviating from the correct sliding path, thereby ensuring the accuracy of the operation. The cover body 11 is provided with a limiting notch 11a, and at least part of the sliding button 31 is exposed from the limiting notch 11a for the user to operate. The user can easily access the sliding button 31 and perform operations, improving the convenience of use.

[0054] In some embodiments, the outer shell cover 10 further includes two rib plates 13 connected to the cover body 11. The two rib plates 13 are respectively located on opposite sides of the limiting notch 11a. The rib plates 13 can be arranged to extend along the up and down direction of the cover body 11, improving the structural strength of the cover body 11 and making it more resistant to mechanical impact and pressure. The rib plates 13 provide additional support for the cover body 11, especially in the area of the limiting notch 11a, reducing the bending or deformation of the cover body 11 and maintaining the stability of its shape.

[0055] In some embodiments, the outer shell cover 10 further includes a mounting portion 14 connected to the cover body 11. The mounting portion 14 provides an assembly area for assembling the buckle plate 32. An opening 15 is provided on the top surface of the cover body 11. A part of the buckle plate 32 can extend out from the opening 15 and engage with the buckle 33. The user can intuitively see the state of the buckle plate 32 through the opening 15 on the top surface of the cover body 11, facilitating confirmation. The outer shell cover 10 further includes a protective boss 16. The protective boss 16 is provided on the top surface of the cover body 11 and is connected to the top surface of the cover body 11. An activity space 16a communicating with the opening 15 is formed inside the protective boss 16. A part of the buckle plate 32 is received in the activity space 16a. A through hole is provided on one side of the protective boss 16 facing the buckle 33. The through hole communicates with the activity space 16a. A part of the buckle plate 32 is clamped with the buckle 33 through the through hole. The protective boss 16 can protect the exposed part of the buckle plate 32 and avoid damage caused by accidental bumping or impact. And the protective boss 16 is more coordinated with the appearance of the cover body 11 and does not affect the overall aesthetics of the cooking appliance 100.

[0056] As Figure 6 and Figure 7 shown, in some embodiments, the sliding knob 31 includes a connected operation part 311 and an assembly part 312. The operation part 311 is disposed in the limit notch 11a, and the user can visually see and touch the operation part 311, making it more direct and easy for the user to slide the sliding knob 31 when opening the lid. The assembly part 312 is located on the side of the cover body 11 facing the inner pot 40, making the outer surface of the cover body 11 cleaner, enhancing the overall aesthetics of the cooking appliance 100, and also being able to reduce the external impact on the assembly part 312.

[0057] The assembly part 312 includes a connected first limit part 3121 and a driving part 3122. The first limit part 3121 is slidably engaged with the guiding part 12 to limit the reciprocating movement of the operation part 311 in the limit notch 11a. By restricting the movement direction of the operation part 311, it ensures that the sliding knob 31 moves in a specific direction, providing precise movement control and preventing sliding in other unexpected directions.

[0058] To improve the stability of the sliding knob 31 sliding in the limit notch 11a, two first limit parts 3121 can be provided, and the two first limit parts 3121 are respectively connected to the opposite sides of the driving part 3122. The number of the guiding part 12 corresponds to that of the first limit part 3121 and the guiding part 12, which can more effectively prevent the sliding knob 31 from shifting or tilting during operation. Moreover, the two first limit parts 3121 can evenly distribute the external force applied by the user, which helps to reduce the wear of the sliding knob 31 during long-term movement and extend its service life.

[0059] Exemplarily, the guiding part 12 is formed as a guiding post, and a guiding hole 3121a is provided on the first limit part 3121. The guiding post is slidably inserted into the guiding hole 3121a. The guiding post can restrict the movement direction of the sliding knob 31. When the user performs the lid-opening operation, the sliding knob 31 can be accurately pushed along the predetermined direction without error, avoiding misoperation and reducing the risk of the sliding knob 31 deviating from the correct path due to improper operation or external force.

[0060] In some embodiments, during the sliding process of the sliding knob 31, the driving part 3122 can be in sliding contact with the buckle 32, and drive the buckle 32 to rotate in a direction away from the lock 33. The direct contact between the driving part 3122 and the buckle 32 provides an efficient force transmission mechanism, ensuring that the buckle 32 can quickly respond to the operation of the sliding knob 31, allowing precise control of the movement of the buckle 32, and enabling the user to accurately operate the lid-opening process.

[0061] In addition to the above-mentioned reset of the sliding button 31 by the top push when the buckle plate 32 rotates, in order to further ensure the reset of the sliding button 31 for the convenience of the user's next sliding operation, the cooking appliance 100 further includes a reset member 50 connected to the cover body 11. The assembly part 312 further includes a second limiting part 3123, and the second limiting part 3123 is connected to the first limiting part 3121 and / or the driving part 3122. The reset member 50 is connected to the second limiting part 3123 and is used to drive the sliding button 31 to reset, ensuring that the sliding button 31 can be reliably reset to the initial position after use and preparing for the next operation.

[0062] Exemplarily, the reset member 50 is a wire spring. The wire spring has a small volume and can provide a large torque in a limited space, which is suitable for compact designs. Moreover, the wire spring is usually made of a highly elastic material and has good durability and a long service life. The two ends of the wire spring are respectively fixedly connected to a rib plate 13. The rib plate 13 provides a stable fixing point to ensure that the two ends of the wire spring do not displace when stretched, maintaining the stability of its function. And the part of the wire spring between its two ends is in limiting cooperation with the second limiting part 3123. The limiting cooperation between the wire spring and the second limiting part 3123 can ensure the stability during the reset process. Exemplarily, when the sliding button 31 is unlocked by sliding downward in the up-down direction, the second limiting part 3123 is connected to the lower side of the driving part 3122. During the process of the user sliding the sliding button 31 downward, the wire spring is stretched and applies an upward force to reset the sliding button 31 to the initial position. Among them, the reset member 50 can also be a spring rib or a spring, and the present application does not limit this.

[0063] Specifically, a card slot 3123a is provided on the second limiting part 3123. The middle part of the tension spring is embedded in the card slot 3123a. Reset holes 13a are provided on the opposite sides of the two rib plates 13. The two ends of the tension spring are respectively inserted into the reset holes 13a. The provision of the card slot 3123a on the second limiting part 3123 facilitates the assembly of the tension spring. During assembly, the two ends of the tension spring are respectively inserted into the reset holes 13a of a rib plate 13, and then the middle part is stuffed into the card slot 3123a, making the assembly process more convenient and fast. Moreover, the settings of the card slot 3123a and the reset holes 13a can provide an accurate assembly position for the tension spring, ensuring the correct installation of the tension spring and reducing assembly errors.

[0064] In some embodiments, the buckle plate 32 includes a main body portion 321, a hook portion 322, and a protruding portion 323. The main body portion 321 is rotatably connected to the mounting portion 14 through a pivot 3211. The mounting portion 14 includes two limiting baffles 141 arranged oppositely. The two limiting baffles 141 are connected to the cover body 11. The main body portion 321 is limited between the two limiting baffles 141. The limiting baffles 141 provide support on both sides for the main body portion 321 of the buckle plate 32, limit the movement range of the main body portion 321, and enhance the structural stability. Both ends of the pivot 3211 are rotatably connected to a limiting baffle 141 respectively. A shaft hole 141a is formed on the limiting baffle 141. Both ends of the pivot 3211 are inserted into the shaft hole 141a. The limiting baffle 141 can provide a stable support point for the buckle plate 32 to ensure that the buckle plate 32 does not tilt or shake during rotation. The design of the pivot 3211 allows the buckle plate 32 to precisely control the angle and position during the opening and closing processes, ensuring the accurate cooperation between a part of the main body portion 321 passing through the opening 15 and the lock 33.

[0065] Specifically, the hook portion 322 is connected to one end of the main body portion 321 passing through the opening 15 and is used for snap - fitting with the lock 33. The design of the hook portion 322 can achieve rapid snap - fitting and unlocking, improving the response speed of opening and closing the lid. The hook portion 322 has an abutting surface, and the abutting surface abuts against the lock 33 in the snap - fitting state to limit the movement of the upper lid 20, ensuring that the upper lid 20 remains stable during the cooking process and preventing accidental opening. The protruding portion 323 is connected to the other end of the main body portion 321 and protrudes along the direction towards the driving portion 3122; wherein, at least a part of the protruding portion 323 is located below the driving portion 3122, so that when the driving portion 3122 is pressed down, a triggering mechanism is formed between the protruding portion 323 and the driving portion 3122, and they can be in sliding contact. When the driving portion 3122 is pressed down, the protruding portion 323 can quickly come into sliding contact with it to achieve a rapid unlocking or triggering action.

[0066] Wherein, the driving portion 3122 has a first abutting surface 3122a, and the protruding portion 323 has a second abutting surface 323a. The first abutting surface 3122a and the second abutting surface 323a are in sliding contact. Among them, one of the first abutting surface 3122a and the second abutting surface 323a is an arc surface, and the other is an inclined surface. The setting of the arc surface can provide a smooth transition, reduce the wear of the buckle plate 32 and the sliding button 31, and extend the service life of the two. The setting of the inclined surface can guide the moving direction, thereby improving the stability of the sliding abutment.

[0067] Exemplarily, such as Figure 8 and Figure 9As shown, the first abutting surface 3122a is an arc surface, and the second abutting surface 323a is an inclined surface. When the driving portion 3122 moves toward the protruding portion 323, the first abutting surface 3122a and the second abutting surface 323a are in sliding contact to form a contact line. When the arc surface and the inclined surface are in contact, the contact area is small, so that the normal force on the contact line is more concentrated per unit area, that is, the cooperation of the arc surface and the inclined surface can generate better thrust, effectively drive the flipping of the buckle plate 32, and make the unlocking effect of the buckle plate 32 more stable. It can be understood that the first abutting surface can also be set as an inclined surface, and the second abutting surface can be set as an arc surface.

[0068] To further ensure that the buckle plate 32 is reset after rotation, the buckle plate 32 also includes an elastic member 60, which is used to make the hook portion 322 have a tendency to rotate in a direction close to the lock buckle 33. After completing the cover opening operation, the user does not need to manually reset the hook portion 322, ensuring that the buckle plate 32 can automatically reset after use. The elastic member 60 can also provide additional support to reduce the shaking of the buckle plate 32 during rotation.

[0069] Specifically, the elastic member 60 can be arranged on the main body 321. For example, the elastic member 60 is a torsion spring. A protrusion 3212 is formed on the main body 321. The torsion spring is sleeved on the protrusion 3212. The torsion spring has good restoring force and can provide a stable reset force for the main body 321, driving the hook 322 to reliably return to the initial position. The compact structure of the torsion spring can provide a large torque in a limited space, which is suitable for the design of a cooking utensil 100 with limited space.

[0070] In another configuration, one end of the elastic member 60 is connected to the main body 321, and the other end is connected to the cover body 11. For example, the elastic member 60 is an elastic rib or a spring, one end of the elastic rib is fixed to the main body 321, and the other end is fixed to the cover body 11. The elastic rib can provide a strong restoring force to ensure that the buckle plate 32 can be reliably reset during the opening and closing process. The elastic rib can store and quickly release energy, providing the buckle plate 32 with power for rapid response. This application does not limit this.
