Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a cooking appliance. Background Art

[0002] At present, most cooking appliances such as rice cookers and electric pressure cookers use hinge springs on the upper cover to open the cover automatically. However, opening the cover too quickly can easily cause the cooker to jump out or tip over during the opening process.

[0003] In the related art, a damping structure is installed between the hinge of the upper cover and the outer shell cover, so that a damping force is generated between the damping member and the outer shell cover to reduce the speed of opening the cover. However, due to the limited elastic deformation amplitude of the damping structure, it is difficult to effectively dissipate the vibration energy. For cooking utensils with a heavier upper cover, it cannot effectively provide a buffering effect. Utility Model Content

[0010] In some embodiments, the damping member includes a main body and a stopper connected to each other, the main body is disposed in the opening, a surface of the main body facing away from the stopper forms the damping surface, and a side of the stopper facing away from the main body is connected to the elastic member;

[0011] In the direction in which the opening enters the channel, the side wall of the stopper is protruding from the side wall of the main body, and the surface of the stopper facing the main body is used to abut against the surface of the support portion facing the limiting portion.

[0012] In some embodiments, a first limiting structure is provided on a side of the stop portion facing away from the main body portion, and the first limiting structure is detachably connected to one end of the elastic member for limiting and fixing.

[0013] In some embodiments, a surface of the stopper portion facing away from the main body portion forms a first guide surface, and the first guide surface is used to guide the elastic member to move toward the first limiting structure;

[0014] And / or, the first limiting structure is located in the middle of a side of the stopper away from the main body;

[0015] And / or, the first limiting structure is a limiting block, and the elastic member slides into and is sleeved on the peripheral side of the limiting block to be plugged and fixed.

[0016] In some embodiments, the limiting portion is provided with a second limiting structure, the second limiting structure is detachably connected to the other end of the elastic member for limiting and fixing, and the second limiting structure is arranged opposite to the first limiting structure.

[0017] In some embodiments, a surface of the limiting portion facing the opening forms a second guide surface, and the second guide surface is used to guide the elastic member to move toward the second limiting structure;

[0018] And / or, the second limiting structure is located in the middle of a side of the limiting portion close to the damping element;

[0026] Based on the cooking appliance according to the embodiments of the present application, by providing a damping assembly including a damping member and an elastic member connected to each other. Thus, when the upper cover is opened relative to the outer casing, the abutting portion of the outer casing abuts against the damping surface of the damping member to cause elastic deformation thereof, and drives the damping member to enter the channel from the opening. In this way, the damping assembly directly utilizes the elastic deformation of the damping member and the movement of the damping member to provide a damping effect. Compared with the traditional solution that only relies on elastic deformation to provide a damping effect, this design can generate more significant energy dissipation. Furthermore, by designing the compression amount of the elastic member, the amplitude of the movement of the damping member relative to the outer casing can be controlled, and thus the opening damping force generated due to the interference between the damping member and the outer casing during opening can be controlled, achieving good control over the opening speed, opening force, and opening effect.

[0027] Meanwhile, by limiting the angle α formed between the damping member and the damping surface within the range of 75° to 85° in the direction of entering the channel from the opening, the damping effect of the damping member is improved. If the angle α is greater than 85°, when the upper cover is opened, the contact part is likely to slip when contacting the damping surface, and the damping effect will be weakened, which may lead to too fast opening speed of the cover, and further cause the risks of pot jumping or even pot overturning. If the angle α is less than 75°, the damping effect will appear prematurely, restricting the opening angle of the upper cover and affecting the user experience. Therefore, the cooking appliance of the present application effectively reduces the occurrence of pot jumping and side overturning phenomena caused by too fast opening of the cover by introducing a damping assembly including a damping member and an elastic member, and optimizing the design of the damping surface of the damping member, improves the safety performance of the cooking appliance, and brings a safer, more stable and smoother user experience to the user.

The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0050] At present, with the development of science and technology and the improvement of people's living standards, more and more cooking utensils have appeared in the kitchen to meet different cooking needs and preferences. These utensils not only improve cooking efficiency, but also enrich the taste and nutrition of food.

[0051] There are many types of cooking appliances, including rice cookers, pressure cookers, electric stew pots, etc. Take rice cookers as an example. The cooking principle of rice cookers is based on the conversion of electrical energy into thermal energy, and the inner pot is heated by built-in heating elements such as heating plates. When the inner pot is heated, the water and rice placed in it begin to heat up, and the water gradually boils and produces steam. The steam rises and penetrates the rice layer, using the high temperature and humidity to cook the rice. Once the rice is cooked, the rice cooker automatically switches to the keep warm mode, which keeps the rice hot and moist by maintaining the appropriate temperature to avoid excessive drying or cooling. The rice cooker is also equipped with intelligent functions and settings, such as appointment timing and multiple recipe selections, to meet the cooking needs of different users.

[0052] Whether it is a rice cooker or an electric pressure cooker, the convenience and operability of its use are the most concerned by the majority of users. At present, most products use a hinge spring set on the upper cover to automatically open the upper cover, but the excessively fast opening speed can easily cause the cooker to jump out or tip over during the opening process.

[0053] In the related technology of opening the lid, a damping structure is installed between the hinge of the upper lid and the outer shell cover, so that a damping force is generated between the damping member and the outer shell cover to reduce the speed of opening the lid. However, due to the limited elastic deformation amplitude of the damping structure, it is difficult to effectively dissipate the vibration energy. For cooking utensils with a heavier upper cover, it is impossible to provide an effective buffering effect.

[0054] Based on this, an embodiment of the present application provides a cooking appliance 100. In the embodiment of the present application, the cooking appliance 100 may include one of a rice cooker, an electric pressure cooker, an air fryer, etc. The specific type of the cooking appliance 100 is not limited in this embodiment. For the convenience of elaborating on the following content, the cooking appliance 100 in the following embodiments is an electric rice cooker, and a detailed introduction is made to the cooking appliance 100 of the present application, which aims to reduce the occurrence of phenomena such as popping the pot and tipping over caused by opening the lid too quickly, improve the safety performance of the cooking appliance 100, and enhance the user experience.

[0055] Refer to Figures 1 to 3 , the cooking appliance 100 in the embodiment of the present application includes an outer shell cover 10, an upper cover 20, and a damping assembly 30.

[0056] The outer shell cover 10 is connected to the upper part of the pot body, mainly playing the roles of heat preservation, preventing heat dissipation, and dust prevention. At the same time, the design of the outer shell cover 10 can also prevent users from accidentally touching the high-temperature inner pot, providing safety protection. The outer shell cover 10 can be supported by plastic materials such as ABS engineering plastics, PP (polypropylene), and PC. The plastic outer shell cover 10 has good insulation performance, moisture-proof performance, wear resistance, and relatively low production costs.

[0057] The upper cover 20 is mechanically connected to the outer shell cover 10 through a hinge shaft to achieve the opening and closing functions. Specifically, a hinge plate is provided on the outer shell cover 10, and the upper cover 20 is equipped with a hinge connection part that matches the hinge shaft. The hinge shaft passes through the hinge connection part of the upper cover 20 and is fixed on the hinge plate, forming a rotation axis. In addition, a torsion spring is sleeved on the hinge shaft, with one end fixed on the outer shell cover 10 and the other end fixed on the upper cover 20. The role of the torsion spring is to provide an auxiliary force for the upper cover 20 during the opening or closing process and maintain the stable state of the upper cover 20. When the open lid button at the front of the electric rice cooker is pressed, the button mechanism will release the restraint on the torsion spring, so that the elastic force of the torsion spring drives the upper cover 20 to rotate around the hinge shaft. As the upper cover 20 rotates, its front part gradually breaks away from the restraint of the outer shell cover 10, and finally the upper cover 20 is fully opened. Such a design not only ensures the convenience of operating the electric rice cooker but also ensures the safety and stability of the lid-opening process.

[0058] Combined with reference to Figure 4, the upper cover 20 is provided with a channel 23 having an opening 231 at one end. This channel 23 not only provides sufficient space for the installation of the damping component 30, but also realizes cost savings and weight reduction by reducing the material usage of the upper cover 20. The damping component 30 includes a connected damping member 31 and an elastic member 32. The damping member 31 is disposed at the opening 231, and the elastic member 32 is disposed in the channel 23. Moreover, the upper cover 20 abuts against one end of the elastic member 32 away from the damping member 31. The surface of the damping member 31 away from the elastic member 32 includes a damping surface 3111 for providing necessary frictional force. The outer shell cover 10 has an abutting portion 11, and the abutting portion 11 is used to abut against the damping surface 3111. The shape of the abutting portion 11 is generally designed to be a structure that can effectively abut against the damping surface 3111 of the damping member 31 of the damping component 30 to adapt to the shape of the damping surface 3111, and can provide a stable and uniform contact area to ensure that the damping member 31 can effectively apply a damping force and is not prone to sliding or dislocation. And the abutting portion 11 is disposed close to the hinge joint of the upper cover 20 and the outer shell cover 10, so as to ensure that it contacts the damping member 31 as soon as possible during the opening of the cover and improve the acting speed of the damping component 30.

[0059] It should be noted that the damping member 31 can be a damping silicone member, a damping rubber member or a PP damping member 31. In this technical solution, selecting a damping silicone member, a damping rubber member or a PP damping member 31 as the damping member 31 of the present application will not generate powder due to wear, further improving the safety performance of the cooking appliance 100 and enhancing the user experience.

[0060] Optionally, the elastic member 32 is a spring piece or a spring. For example, when it is a spring, it can be specifically arranged in a columnar shape. Thus, when the abutting portion 11 abuts against the damping surface 3111 of the damping member 31, the opening force will be transmitted to the elastic member 32 through the damping member 31. Since one end of the elastic member 32 away from the damping member 31 is abutted by the upper cover 20, the elastic member 32 is compressed, so that the damping member 31 enters the channel 23 from the opening 231, improving the damping effect, not only ensuring the stability and reliability of the damping member 31 during operation, but also making the weight of the entire damping component 30 smaller due to the elastic member 32 of the spring or the spring piece.

[0061] In another embodiment, the damping member 31 and the elastic member 32 are an integrated structure. Specifically, the damping member 31 and the elastic member 32 can both be made of elastic materials such as silicone, the damping member 31 can be a rectangular or trapezoidal block, and the elastic member 32 can be a long strip structure and extend from the opening 231 to the channel 23. In this way, when the abutting portion 11 abuts the damping surface 3111 of the damping member 31, the force of opening the cover will be transmitted to the elastic member 32 through the damping member 31. Since the end of the elastic member 32 away from the damping member 31 is abutted by the upper cover 20, the elastic member 32 is deformed, and the damping member 31 also enters the channel 23 from the opening 231. The integrated design not only simplifies the structure and manufacturing process of the damping assembly 30 and reduces the production cost, but also further enhances the overall performance and stability of the damping assembly 30. Since the damping member 31 and the elastic member 32 are closely combined, they can work more harmoniously and provide a better damping effect together. Additionally, this integrated design reduces the risk of failure due to loose or damaged components.

[0062] Based on the cooking appliance 100 of the embodiment of the present application, the damping assembly 30 includes a damping member 31 and an elastic member 32 connected to each other. Therefore, when the upper cover 20 is opened relative to the outer shell 10, the abutting portion 11 of the outer shell 10 abuts against the damping surface 3111 of the damping member 31 to cause elastic deformation, and drives the damping member 31 to enter the channel 23 from the opening 231. In this way, the damping assembly 30 directly utilizes the elastic deformation of the damping member 31 and moves the damping member 31 to provide a damping effect. Compared with the traditional solution that only relies on elastic deformation to provide a damping effect, this design can generate more significant energy dissipation, and then by designing the compression amount of the elastic member 32, the amplitude of the movement of the damping member 31 relative to the outer shell 10 can be controlled, and then the cover-opening damping force generated by the interference between the damping member 31 and the outer shell 10 when opening the cover can be controlled, so as to achieve good control of the cover-opening speed, cover-opening force and cover-opening effect.

[0063] Combined with reference Figure 4 and Figure 5, meanwhile, by defining that the angle α formed between the direction AA of the damping member 31 entering the channel 23 through the opening 231 and the damping surface 3111 ranges from 75° to 85°, the damping effect of the damping member 31 is improved. The damping member 31 is placed on the bearing surface of the upper cover 20. It can be understood that the angle between the damping surface 3111 and the bearing surface is α. If the angle α is greater than 85°, when the upper cover 20 is opened, the abutting portion 11 is likely to slip when contacting the damping surface 3111, and the damping effect will be weakened, which may lead to too fast opening speed of the cover, and then trigger the risks of pot jumping or even pot overturning. If the angle α is less than 75°, the damping effect will appear prematurely, restricting the opening angle of the upper cover 20 and affecting the user experience. Therefore, the cooking appliance 100 of the present application effectively reduces the occurrence of pot jumping and side turning phenomena caused by too fast opening of the cover by introducing the damping assembly 30 including the damping member 31 and the elastic member 32, and optimizing the design of the damping surface 3111 of the damping member 31, improves the safety performance of the cooking appliance 100, and brings a safer, more stable and smoother user experience to the user.

[0064] Referring to Figure 4 and Figure 5 , in some structural forms, the surface of the damping member 31 facing away from the elastic member 32 further includes an arc transition surface 3112 and a vertical surface 3113, and the arc transition surface 3112 and the vertical surface 3113 are connected to opposite sides of the damping surface 3111. Among them, when the upper cover 20 is opened relative to the outer housing 10, the abutting portion 11 generates frictional forces with the arc transition surface 3112, the damping surface 3111, and the vertical surface 3113 in sequence.

[0065] In this technical solution, by setting the contact surface between the damping member 31 and the abutting portion 11 as the arc transition surface 3112, the damping surface 3111, and the vertical surface 3113 connected in sequence, the force adjustment during the opening and closing of the cover is realized. Referring to Figure 6 and Figure 7 , when the upper cover is closed, the abutting portion 11 is not in contact with the damping member 31. Referring to Figure 8 and Figure 9 , when the opening angle of the cover is from 40° to 80°, the damping member 31 first contacts the arc transition surface 3112. This design reduces the friction and impact in the initial stage and makes the opening process of the cover smoother. As the damping member 31 moves to the damping surface 3111, appropriate frictional resistance is introduced, effectively slowing down the opening speed of the cover. Referring to Figure 10 and Figure 11 , when the cover is opened to 80° to 90°, the damping interference amount is the largest, and when the damping member 31 finally contacts the vertical surface 3113, the increased frictional force ensures that the upper cover 20 can stay stably when reaching the set angle, further reducing the occurrence of pot jumping phenomenon. The whole design cleverly combines the contact surfaces of different shapes to ensure the smoothness, stability and safety of the opening and closing process of the cover.

[0066] Referring to Figure 2 , optionally, the channel 23 includes at least two channels 23, and the two channels 23 are respectively opened on the relatively arranged upper cover 20 and are symmetrically arranged with respect to the vertical center plane of the abutting portion 11. In this technical solution, the channels 23 are symmetrically opened on the upper cover 20, and a damping component 30 is arranged at each channel 23, so that the opposite ends of the abutting portion 11 can be contacted and damped, thereby improving the force balance of the upper cover 20 during the process of opening the cover, further reducing the occurrence of phenomena such as boiling over and tipping over, and improving the safety performance of the cooking appliance 100.

[0067] With reference to Figure 4 、 Figure 5 and Figure 12 , in some structural forms, the upper cover 20 includes a face cover 21 and an inner cover 22 which are connected. The face cover 21 is installed on the outermost part and plays roles such as installing components, protecting and beautifying. Among them, the face cover 21 can be composed of at least two different materials such as plastic, glass, and metal spliced together. In this way, while having a high structural strength, it can also have better appearance shapes, glossiness and other characteristics, which can improve the aesthetics of the entire cooking appliance 100.

[0068] The inner cover 22 is fixed inside the face cover 21, and the inner cover 22 is hinged to the outer shell cover 10. In one structural form, the inner cover 22 is annular. By connecting the face cover 21 and the inner cover 22 to enclose the channel 23, compared with the traditional way of forming the channel 23 by punching holes, the forming scheme of the channel 23 in this application is more concise and efficient, and is convenient for installing and subsequent maintenance and replacement of the damping member 31 and the elastic member 32 in the through hole. The inner cover 22 is provided with an opening 231, and at least one of the damping member 31 and the elastic member 32 is connected to the inner cover 22. That is, one of the damping member 31 and the elastic member 32 is connected to the inner cover 22. For example, after the damping member 31 is connected to the inner cover 22, the position of the elastic member 32 is relatively fixed with respect to the inner cover 22, so as to reduce the installation steps and improve the installation efficiency. Of course, it is also possible to connect the damping member 31 and the elastic member 32 to the inner cover 22 at the same time, so as to improve the stability of the damping member 31 and the elastic member 32 in the channel 23.

[0069] Further, the inner cover 22 includes a support portion 221 and a limiting portion 222. The limiting portion 222 is connected to the support portion 221 and is located within the channel 23. Herein, the support portion 221 and the limiting portion 222 may be an integral structure, thus eliminating the assembly process and ensuring the stability of the overall structure of the inner cover 22. The support portion 221 is connected to the face cover 21, specifically, it can be connected by means such as snaps or screws for easy disassembly and assembly later. The support portion 221 is provided with an opening 231, and the damping member 31 can be directly placed and supported on the support portion 221, so that the installation of the damping member 31 is more convenient and fast without the need for other tools. The limiting portion 222 is disposed opposite to the opening 231, and one side of the elastic member 32 facing away from the damping member 31 is connected to the limiting portion 222. Such a connection method ensures that the elastic member 32 can maintain a stable position when subjected to an external force and is also convenient for deformation, thereby more effectively moving the damping member 31. Generally speaking, this structural design of the inner cover 22 not only improves the stability but also pays attention to the convenience of installation and maintenance. At the same time, it is also convenient for the deformation of the damping member 31 and the elastic member 32 to improve the damping effect.

[0070] Furthermore, the damping member 31 includes a main body portion 311 and a stop portion 312 connected to each other. The main body portion 311 is disposed within the opening 231. The surface of the main body portion 311 facing away from the stop portion 312 forms a damping surface 3111. One side of the stop portion 312 facing away from the main body portion 311 is connected to the elastic member 32. In the direction in which the opening 231 enters the channel 23, the side wall of the stop portion 312 protrudes from the side wall of the main body portion 311, and the surface of the stop portion 312 facing the main body portion 311 is used to abut against the surface of the support portion 221 facing the limiting portion 222. Thus, by abutting the support portion 221 against the stop portion 312, the position of the stop portion 312 is limited, preventing the main body portion 311 from accidentally slipping out from the side of the opening 231 facing away from the channel 23, and ensuring that the elastic member 32 is stably located within the channel 23. Once the damping assembly 30 is installed in this way, it can maintain stability and exert the expected damping effect. This not only improves the reliability and durability but also ensures the damping effect.

[0071] Further, in order to ensure the stability and reliability of the damping assembly 30 during long-term use, a first limiting structure 3121 is provided on one side of the stop portion 312 facing away from the main body portion 311. The first limiting structure 3121 is detachably connected to one end of the elastic member 32 for limiting and fixing. Thus, when the first limiting structure 3121 is firmly connected to one end of the elastic member 32, the damping member 31 is not easily displaced or detached when subjected to an external force, thereby ensuring the durability and consistency of the damping effect. At the same time, this detachable connection method also makes subsequent maintenance and replacement work simpler and more convenient, bringing great convenience to users.

[0072] Refer to Figure 4and Figure 5 , optionally, a first guiding surface 3122 is formed on the surface of the stopper portion 312 facing away from the main body portion 311, and the first guiding surface 3122 is used to guide the elastic member 32 to move towards the first limiting structure 3121. Wherein, the first guiding surface 3122 can be an inclined surface, a curved surface or a plane with a specific shape, so as to better guide the movement track of the elastic member 32. By reasonably designing the shape and angle of the first guiding surface 3122, the installation process can be made smoother, the operation difficulty can be reduced, and at the same time, the installation accuracy and stability can be improved.

[0073] Optionally, the first limiting structure 3121 is located in the middle of the side of the stopper portion 312 facing away from the main body portion 311. In this way, it can be ensured that the elastic member 32 receives a uniform force distribution when connected to the stopper portion 312, thereby increasing the stability and reliability of the connection. In addition, the middle position is also easier to install and disassemble.

[0074] Optionally, the first limiting structure 3121 is a limiting block 312a, and the elastic member 32 slides into and sleeves on the peripheral side of the limiting block 312a for plug-in fixation. The plug-in fixation method not only ensures that the damper 31 and the elastic member 32 are not easily separated during use, providing a stable and reliable damping effect, but also the installation process is relatively convenient to improve the installation efficiency. In order to further optimize the plug-in efficiency, we can design the surface of the limiting block 312a facing away from the main body portion 311 as an inclined surface. Such a design can make the elastic member 32 easier and smoother to slide into and sleeve on the limiting block 312a, further improving the convenience of the installation process. Of course, in addition to the design of the limiting block 312a, the first limiting structure 3121 can also have other forms. For example, in another embodiment, the first limiting structure 3121 can also be a groove on the surface of the stopper portion 312 facing away from the main body portion 311. When installing, the elastic member 32 can slide into this groove for fixation, and the same stable and reliable damping effect can be achieved.

[0075] Referring to Figure 4 and Figure 13, in some structural forms, the limiting part 222 is provided with a second limiting structure 2221. The second limiting structure 2221 is detachably connected to the other end of the elastic member 32 for limiting and fixing, and the second limiting structure 2221 is arranged opposite to the first limiting structure 3121. Such a design enables both ends of the elastic member 32 to be effectively fixed and supported when subjected to the opening force, thereby reducing the risk of accidental detachment or displacement. At the same time, since the second limiting structure 2221 and the first limiting structure 3121 are arranged opposite to each other, they can form a stable force balance system, further enhancing the overall stability of the damping assembly 30. During the installation process, one end of the elastic member 32 can be connected to the first limiting structure 3121, and the other end can be connected to the second limiting structure 2221, thereby quickly and accurately completing the assembly of the damping assembly 30. This detachable connection method also makes subsequent maintenance and replacement work simpler and more convenient.

[0076] Furthermore, the surface of the limiting part 222 facing the opening 231 forms a second guiding surface 2222, and the second guiding surface 2222 is used to guide the elastic member 32 to move towards the second limiting structure 2221. Among them, the second guiding surface 2222 can be an inclined surface, a curved surface or a plane with a specific shape, so as to better guide the movement trajectory of the elastic member 32. By reasonably designing the shape and angle of the second guiding surface 2222, the installation process can be made smoother, the operation difficulty can be reduced, and at the same time, the installation accuracy and stability can be improved. In addition, the second guiding surface 2222 and the first guiding surface 3122 can be arranged opposite to each other, so that the elastic member 32 and the damping member 31 can be installed synchronously under the guiding action, improving the installation efficiency.

[0077] Optionally, the second limiting structure 2221 is located in the middle of the side of the limiting part 222 close to the damping member 31. This can ensure that the elastic member 32 and the limiting part 222 receive a uniform force distribution during connection, thereby increasing the stability and reliability of the connection. In addition, the middle position is also easier to install and disassemble.

[0078] Optionally, the second limiting structure 2221 includes an insertion block 222c, and the elastic member 32 slides into and sleeves around the circumferential side of the insertion block 222c for plug-in fixation. In this way, the other end of the elastic member 32 can easily slide into and sleeve around the circumferential side of the insertion block 222c to achieve plug-in fixation. This design not only simplifies the installation process but also ensures the stability and reliability of the connection, providing users with a convenient and comfortable use experience.

[0079] Refer to Figure 14In another embodiment, the second limiting structure 2221 includes a positioning block 222a and a supporting block 222b connected to each other, the supporting block 222b is connected to the limiting portion 222, and the side of the positioning block 222a away from the supporting block 222b is recessed to form a positioning groove 222A, and at least part of the elastic member 32 is embedded in the positioning groove 222A. The existence of the positioning groove 222A provides a clear installation position for the elastic member 32, making the installation process more intuitive and accurate. Secondly, the combination of the positioning block 222a and the supporting block 222b ensures the stability of the connection, so that the damping assembly 30 is not easily displaced or falls off when subjected to external force. Finally, this design also takes into account space optimization, making the overall structure of the damping assembly 30 more compact and suitable for various application scenarios. In general, the design of the second limiting structure 2221 with the positioning block 222a and the supporting block 222b improves the installation efficiency and stability of the damping assembly 30. In addition, a protrusion may be provided on the bottom surface of the positioning groove 222A, and the protrusion is inserted and fixed in the elastic member 32 to further improve the stability of the connection with the elastic member 32.
