Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric rice cookers, in particular to an electric rice cooker opening and closing adjusting structure and electric rice cooker. BACKGROUND

[0002] In daily life, as a common kitchen appliance, the convenience and stability of electric rice cookers are crucial to improving the cooking experience. However, the structural design of existing electric rice cookers has exposed some problems that need to be improved in practical application.

[0003] The current market electric rice cooker generally adopts the structure that the pot cover and the pot body are connected through a hinge. This fixed connection method makes the relative position of the pot cover and the hinge shaft unadjustable. In addition, the compression amount of the buffer block of the existing electric rice cooker also cannot be effectively adjusted, and the core function of the buffer block is to realize buffering during the opening and closing of the cover, which can not only protect the parts of the electric rice cooker, but also ensure the tightness of the cover. However, due to the lack of adjusting means, the compression amount of the buffer block cannot be adaptively adjusted according to different use scenarios and user needs. This leads to the phenomenon of jumping of the electric rice cooker when opening the cover, which not only affects the user experience, but also may cause damage to the electric rice cooker itself. At the same time, due to the unreasonable compression amount of the buffer block, the cover may not be closed tightly, which affects the sealing performance of the electric rice cooker, causes heat loss during cooking, affects the cooking effect, and may even cause safety hazards.

[0004] In summary, the pot cover connection structure and buffer block compression amount adjustment problem of the existing electric rice cooker seriously affect the user experience and the performance stability of the electric rice cooker, therefore, an improved structure is needed to solve the above problems to meet the diversified needs of users in different scenarios and improve the overall use performance of the electric rice cooker.

In addition, those skilled in the art can combine and combine different embodiments or examples described in the present application.

[0029] Referring to Figures 1 to 7 As shown, the present application discloses a specific embodiment of an electric rice cooker opening and closing adjusting structure, which comprises a pot cover 10 and a pot body 20, the pot cover 10 is provided with an elastic buffer block 30, the pot body 20 is provided with a support frame 40 and a hinge shaft 50, the support frame 40 is provided with a long limiting hole 41, the hinge shaft 50 passes through the long limiting hole 41 and is rotationally connected to the pot cover 10, the hinge shaft 50 is further sleeved with a hinge spring piece 60, one end of the hinge spring piece 60 is connected to the pot cover 10, and the other end is connected to the support frame 40; when the pot cover 10 and the pot body 20 are in an open state, the elastic buffer block 30 abuts against the support frame 40 and generates compression deformation; the front and rear positions of the hinge shaft 50 in the long limiting hole 41 are adjusted to adjust the compression deformation amount of the elastic buffer block 30.

[0030] Specifically, the cover 10 and the body 20 are basic components of the electric rice cooker. The cover 10 is used to close the body 20 to ensure the sealing during the cooking process. The elastic buffer block 30 is installed on the cover 10, which has good elasticity and can provide a buffering effect during the opening and closing of the cover. The support frame 40 is fixed on the body 20 and is used to support the cover 10 and cooperate with the elastic buffer block 30 to achieve the buffering function. The support frame 40 is provided with two parallel long limiting holes 41, which provide adjustable mounting positions for the hinge shaft 50. The hinge shaft 50 passes through the long limiting holes 41 of the support frame 40 and is rotationally connected with the cover 10. By adjusting the front and back positions of the hinge shaft 50 in the long limiting holes 41, the relative position relationship between the cover 10 and the support frame 40 can be changed. The hinge spring member 60 is sleeved on the hinge shaft 50, one end of which is connected to the cover 10 and the other end is connected to the support frame 40. The hinge spring member 60 provides an elastic force during the opening and closing of the cover 10, assists the opening and closing action of the cover 10, and cooperates with the elastic buffer block 30 to achieve the buffering function.

[0031] Before adjustment, the hinge shaft 50 is located at an initial position of the long limiting hole 41, and the distance and contact pressure between the elastic buffer block 30 and the support frame 40 are in a default state. The user adjusts the front and back positions of the hinge shaft 50 in the long limiting hole 41 according to needs by a tool or manually. For example, if it is needed to increase the buffering degree when opening the cover, the hinge shaft 50 can be moved forward, so that the position of the elastic buffer block 30 abutting against the support frame 40 changes when the cover is opened, thereby increasing the pressure on the elastic buffer block 30; conversely, if it is needed to reduce the buffering degree, the hinge shaft 50 can be moved backward.

[0032] When the cover 10 is opened, the elastic buffer block 30 abuts against the support frame 40 and is compressed. Due to the adjustment of the position of the hinge shaft 50, the elastic buffer block 30 is subjected to different pressures from the support frame 40, thereby adjusting the compression deformation amount of the elastic buffer block 30. The change of the compression deformation amount directly affects the buffering degree of the elastic buffer block 30 during the opening of the cover, and precise adjustment of the opening buffering effect is achieved.

[0033] In order to ensure the stability of the adjusted position of the hinge shaft 50, a locking mechanism can be provided between the hinge shaft 50 and the long limiting hole 41. For example, a nut tightening method is used to fix the hinge shaft 50 at a specific position in the long limiting hole 41, or a buckle structure is designed so that the hinge shaft 50 can be firmly locked after being adjusted to the appropriate position, preventing the position of the hinge shaft 50 from changing due to vibration and other reasons during use.

[0034] That is, by adjusting the front and rear position of the hinge shaft 50 in the long limiting hole 41, the compression deformation amount of the elastic buffer block 30 when the cover is opened can be accurately changed; when the pot cover 10 is opened, the elastic buffer block 30 abuts against the support frame 40, and the pressure it receives will change with the change of the position of the hinge shaft 50, thereby realizing the adjustment of the buffering degree. This adjustment method can flexibly adjust the opening buffering effect according to the actual use needs of users and different scenes, and ensure that the opening process is smooth and smooth. In addition, by adjusting the front and rear position of the hinge shaft 50 in the long limiting hole 41, the front and rear position of the pot cover 10 changes synchronously, thereby controlling the compression amount of the elastic buffer block 30, which can prevent the pot cover 10 from jumping due to insufficient buffering during the closing process, and improve the use comfort. In addition, different users may have different operation habits and use scenes when using the electric rice cooker; the opening and closing adjustment structure can meet the diversified needs of users in different scenes. Users can adjust the buffering degree at any time according to their own preferences and actual use, so that the operation of the electric rice cooker is more personalized and humanized. This high adjustability makes the electric rice cooker better adapt to various complex use environments, and provides users with more comfortable and convenient use experience.

[0035] Referring to Figures 1 to 5 As shown in the embodiment, the support frame 40 is also provided with a support rib assembly, and the hinge shaft 50 contacts the support rib assembly to form a multi-stage limiting structure.

[0036] Specifically, the support rib assembly is part of the support frame 40 and is composed of a plurality of support ribs, and forms a plurality of limiting points. Each support rib has a contact surface for contacting the hinge shaft 50 to limit the position of the hinge shaft 50. The hinge shaft 50 passes through the long limiting hole 41 and is rotationally connected with the pot cover 10. The position of the hinge shaft 50 in the long limiting hole 41 can be multi-stage limited by contacting the support rib assembly.

[0037] Before adjustment, the hinge shaft 50 is located at a certain initial position in the long limiting hole 41 and contacts one of the support ribs. At this time, the compression deformation amount of the elastic buffer block 30 is in the default state. The user adjusts the front and rear position of the hinge shaft 50 in the long limiting hole 41 by a tool or manually according to needs. When the hinge shaft 50 moves to different positions, it will contact different support ribs. The position of each support rib corresponds to a specific buffering degree level.

[0038] That is, by setting the support rib assembly, a multi-stage limiting structure is formed, so that users can choose different buffer intensity levels according to different use scenarios and needs. This multi-stage adjustment method is more accurate and convenient than single continuous adjustment, and users can quickly find the most suitable buffer intensity for themselves. In addition, the multi-stage limiting structure limits the position of the hinge shaft 50 through the contact surface of the support rib, so that the adjusted buffer intensity is more stable. After adjusting to the appropriate position, the user can further ensure the stability of the position through the locking mechanism, avoid the change of the position of the hinge shaft 50 due to vibration or other external force, and thus ensure the consistency and reliability of the buffer intensity.

[0039] Referring to Figures 1 to 7 As shown in the drawings, in an embodiment, the support rib assembly includes a first support rib 42, a second support rib 43, and a third support rib 44, all of which are provided with a limiting groove. A first shaft sleeve 70 is also provided between the hinge spring member 60 and the hinge shaft 50, which is in contact with the limiting groove of the first support rib 42. A second shaft sleeve 80 is also provided on the middle segment of the hinge shaft 50, which is in contact with the limiting groove of the second support rib 43 or the limiting groove of the third support rib 44.

[0040] Specifically, the support rib assembly includes a first support rib 42, a second support rib 43, and a third support rib 44. These three support ribs are located in the area between the two long limiting holes 41, and each support rib is provided with a limiting groove. The first shaft sleeve 70 is installed between the hinge spring member 60 and the hinge shaft 50, and its outer surface is in contact with the limiting groove of the first support rib 42. The second shaft sleeve 80 is installed on the middle segment of the hinge shaft 50, and its outer surface can be in contact with the limiting groove of the second support rib 43 or the limiting groove of the third support rib 44.

[0041] Initial state: The two ends of the hinge shaft 50 are respectively inserted into the two long limiting holes 41, the first shaft sleeve 70 is in contact with the limiting groove of the first support rib 42, and plays a preliminary limiting role. The second shaft sleeve 80 is in contact with the limiting groove of the second support rib 43, and the hinge shaft 50 is in a certain initial position in the long limiting hole 41.

[0042] Adjustment operation: The user can move the second shaft sleeve 80 from the limiting groove of the second support rib 43 to the limiting groove of the third support rib 44, or vice versa, as needed. When the second shaft sleeve 80 is in contact with the limiting groove of different support ribs, the position of the hinge shaft 50 in the long limiting hole 41 will change.

[0043] In other words, a multi-level limiting structure is formed by setting two long limiting holes 41 and multiple support ribs. Users can select different levels of cushioning force according to different usage scenarios and needs. This multi-level adjustment method is more precise and convenient than single continuous adjustment, allowing users to quickly find the most suitable cushioning force. In addition, the multi-level limiting structure restricts the position of the second bushing 80 through the limiting grooves of the support ribs, thereby restricting the position of the hinge shaft 50, making the adjusted cushioning force more stable.

[0044] See Figures 6 to 7 As shown, in one embodiment, the arc diameter of the limiting groove of the second support rib 43 and the limiting groove of the third support rib 44 is D2, the outer diameter of the second bushing 80 is D1, and D2 is 0.1mm-0.15mm larger than D1.

[0045] Specifically, since the arc diameter D2 of the limiting groove is slightly larger than the outer diameter D1 of the second bushing 80, this design allows the second bushing 80 to have a certain amount of room to move within the limiting groove, but it is tight enough to maintain the limiting function.

[0046] In other words, by designing the arc diameter D2 of the limiting groove to be slightly larger than the outer diameter D1 of the second bushing 80 (0.1mm-0.15mm), this dimensional relationship ensures that the second bushing 80 can be precisely limited within the limiting groove. This design allows the second bushing 80 some room to move within the limiting groove, yet it is tight enough to maintain the limiting function, thereby ensuring the stability of the hinge shaft 50's position. Furthermore, this precise dimensional design makes the position of the second bushing 80 more stable within the limiting groove, reducing displacement caused by manufacturing tolerances or wear during use.

[0047] See Figures 6 to 7 As shown, in one embodiment, when the second bushing 80 contacts the limiting groove of the third support rib 44, the distance between the innermost side of the limiting groove of the third support rib 44 and the root of the third support rib 44 is H1; when the second bushing 80 contacts the limiting groove of the second support rib 43, the distance between the innermost side of the limiting groove of the second support rib 43 and the root of the second support rib 43 is H2, and H2 is greater than H1.

[0048] Specifically, the distance between the innermost side of the limiting groove of the third support rib 44 and the root of the third support rib 44 is H1. The distance between the innermost side of the limiting groove of the second support rib 43 and the root of the second support rib 43 is H2, and H2>H1. Since H2>H1, when the second bushing 80 contacts different supporting rib limiting grooves, the front-to-back position of the hinge shaft 50 within the long limiting hole 41 will change.

[0049] That is, by designing the limiting groove distance H1 and H2 of the second support rib 43 and the third support rib 44, the position of the hinge shaft 50 in the long limiting hole 41 is different when the second shaft sleeve 80 contacts different limiting grooves. This design achieves a multi-stage buffer adjustment function, and users can choose different buffer levels according to different use scenarios and needs. This multi-stage adjustment method is more accurate and convenient than single continuous adjustment, and users can quickly find the most suitable buffer level for themselves. In addition, since H2>H1, when the second shaft sleeve 80 moves from the limiting groove of the second support rib 43 to the limiting groove of the third support rib 44, the position of the hinge shaft 50 will change significantly. This design ensures the stability and reliability of the adjustment process, and users can clearly feel the difference in buffer level at different positions. In addition, by precisely designing the distance H1 and H2 of the limiting groove, the stability and reliability of the overall structure are optimized. This design not only achieves multi-stage limiting function, but also improves the space utilization, making the overall design of the electric rice cooker more compact and reasonable.

[0050] In an embodiment, the difference between H2 and H1 is 0.25mm-0.4mm.

[0051] Specifically, the difference between H2 and H1 is 0.25mm-0.4mm, i.e. 0.25mm≤H2−H1≤0.4mm.

[0052] Assume: H1=5.0mm; H2=5.25mm or H2=5.4mm. In this case: when the second shaft sleeve 80 contacts the limiting groove of the third support rib 44, the position of the hinge shaft 50 will move forward because H1 is smaller. When the second shaft sleeve 80 contacts the limiting groove of the second support rib 43, the position of the hinge shaft 50 will move backward because H2 is larger. This design allows users to adjust the position of the second shaft sleeve 80 to change the forward and backward position of the hinge shaft 50 in the long limiting hole 41, thereby adjusting the compression deformation of the elastic buffer block 30 to achieve different buffer levels. Specifically, when H2−H1=0.25mm, the change in buffer level is relatively moderate; when H2−H1=0.4mm, the change in buffer level is more obvious, and users can choose the appropriate adjustment range according to their needs.

[0053] That is, by designing the difference between H2 and H1 to be 0.25mm-0.4mm, this precise size difference allows the position of the hinge shaft 50 in the long limiting hole 41 to change clearly when the second shaft sleeve 80 contacts different limiting grooves. Users can choose different buffer levels according to different use scenarios and needs.

[0054] Referring to Figures 1 to 5As shown, in an embodiment, a first limiting rib 45 is further arranged between the second support rib 43 and the third support rib 44, a second limiting rib 46 is further arranged on the side of the second support rib 43 away from the third support rib 44, and a third limiting rib 47 is further arranged on the side of the third support rib 44 away from the second support rib 43; when the second shaft sleeve 80 contacts the limiting groove of the second support rib 43, the two ends of the second shaft sleeve 80 abut against the first limiting rib 45 and the second limiting rib 46 respectively; when the second shaft sleeve 80 contacts the limiting groove of the third support rib 44, the two ends of the second shaft sleeve 80 abut against the first limiting rib 45 and the third limiting rib 47 respectively.

[0055] Specifically, by arranging the first limiting rib 45 between the second support rib 43 and the third support rib 44, and arranging the second limiting rib 46 and the third limiting rib 47 on the two sides of the second support rib 43 and the third support rib 44 respectively, this design ensures the stability of the second shaft sleeve 80 in different positions. Specifically: when the second shaft sleeve 80 contacts the limiting groove of the second support rib 43, the two ends of the second shaft sleeve 80 abut against the first limiting rib 45 and the second limiting rib 46 respectively. When the second shaft sleeve 80 contacts the limiting groove of the third support rib 44, the two ends of the second shaft sleeve 80 abut against the first limiting rib 45 and the third limiting rib 47 respectively. This design makes the second shaft sleeve 80 not shift left and right in any position, thereby ensuring the accuracy and stability of adjustment.

[0056] In an embodiment, the number of hinge spring members 60 is two, and each is arranged on the left and right sides of the hinge shaft 50.

[0057] Specifically, by arranging two hinge spring members 60 on the left and right sides of the hinge shaft 50 respectively, this double-spring configuration can provide more uniform and stable elastic force during the opening and closing of the pot cover 10. The specific effects are as follows: Cover opening process: When the user opens the pot cover 10, the two hinge spring members 60 simultaneously provide elastic force, making the opening process of the pot cover 10 more stable, avoiding shaking or jamming due to insufficient unilateral spring force.

[0058] Cover closing process: When the user closes the pot cover 10, the two hinge spring members 60 also provide uniform elastic force, ensuring that the pot cover 10 can be closed smoothly and smoothly, reducing the closure or impact due to insufficient unilateral spring force.

[0059] In addition, the double-spring configuration not only improves the stability of the opening and closing of the pot cover 10, but also enhances the stability and reliability of the entire adjustment system. The specific manifestations are as follows: Reducing vibration: The uniform elastic force of the double spring can effectively reduce the vibration of the pot cover 10 during opening and closing, improving the user experience.

[0060] Long service life: uniform elastic force distribution reduces the wear and tear of parts, prolonging the overall service life of the rice cooker.

[0061] In an embodiment, the elastic buffer block 30 is made of silicone material.

[0062] Specifically, the elastic buffer block 30 is made of silicone. The elastic buffer block 30 is installed on the lid 10 and cooperates with the support frame 40 to provide a buffering effect during the opening and closing of the lid. The elastic buffer block 30 is usually designed as a circle or a rectangle, and the specific shape is optimized according to the structure of the lid 10 and the support frame 40 to ensure good contact and buffering effect.

[0063] That is, the silicone material has excellent elastic properties and can provide stable buffering force during the opening and closing of the lid 10. Specifically, it has the following advantages: Good buffering effect: the silicone buffer block can effectively absorb impact force during the opening and closing of the lid, reducing direct collision between the lid 10 and the support frame 40, protecting the parts of the rice cooker and prolonging the service life.

[0064] Strong recovery performance: silicone can quickly recover to its original state after being pressed, ensuring consistent buffering effect each time the lid is opened or closed, and avoiding insufficient buffering force caused by deformation of the buffer block.

[0065] In addition, the silicone material has good high-temperature resistance and can be used in the high-temperature environment of the rice cooker for a long time without performance degradation. Specifically, it has the following advantages: High temperature resistance: silicone can maintain stable physical properties in the high-temperature environment of the rice cooker and will not become hard or brittle due to high temperature, ensuring the durability of the buffering effect.

[0066] Long service life: the high-temperature resistance of silicone makes the buffer block less likely to age during the use of the rice cooker, prolonging the service life of the buffer block and reducing the frequency of replacement.

[0067] In addition, the silicone material has good chemical stability and will not react with food or cleaning agents in the rice cooker. Specifically, it has the following advantages: Safe and non-toxic: silicone material is non-toxic and odorless, meeting the safety standards of food contact materials, ensuring that no harmful substances are released during cooking.

[0068] Corrosion resistant: silicone can resist corrosion from common cleaning agents, making it easy for users to clean and maintain the rice cooker and keeping the rice cooker hygienic and functional.

[0069] In an embodiment, the hinge spring member 60 is made of stainless steel material.

[0070] Specifically, the hinge spring member 60 is made of stainless steel, typically 304 or 316 stainless steel, which has good corrosion resistance and mechanical properties.

[0071] Among them, stainless steel materials (such as 304 or 316) have excellent corrosion resistance and can be used in humid or corrosive environments for a long time without rust. The specific performance is as follows: Moisture resistance: stainless steel springs can be used in the humid environment of the kitchen for a long time and will not rust due to moisture or steam.

[0072] Corrosion resistance to cleaning agents: stainless steel can resist the corrosion of common cleaning agents, making it easy for users to clean and maintain the rice cooker.

[0073] In addition, stainless steel materials have high strength and toughness, which can withstand a large stress. The specific performance is as follows: High elastic coefficient: stainless steel springs have a high elastic coefficient, which can provide stable elastic force during the opening and closing of the lid 10.

[0074] Good fatigue resistance: stainless steel springs can withstand repeated cyclic loading and are not prone to fatigue fracture.

[0075] In addition, stainless steel materials are suitable for a wide temperature range of about -60℃ to 250℃. The specific performance is as follows: High temperature resistance: stainless steel springs can maintain stable physical properties in the high temperature environment of the rice cooker and will not soften or deform due to high temperature.

[0076] Low temperature resistance: in low temperature environment, stainless steel springs can also maintain good elastic properties.

[0077] The present application also discloses an electric rice cooker comprising the electric rice cooker opening and closing adjusting structure as described above.

[0078] Specifically, by adjusting the front and rear positions of the hinge shaft 50 in the long limiting hole 41, the compression deformation amount of the elastic buffer block 30 when the lid 10 is opened can be accurately changed. When the lid 10 is opened, the elastic buffer block 30 abuts against the support frame 40, and the pressure it receives will change with the position of the hinge shaft 50, thereby achieving adjustment of the buffering force. This adjustment method can flexibly adjust the opening buffering effect according to the actual use requirements of users and different scenarios, ensuring a smooth and smooth opening process. In addition, by adjusting the front and rear positions of the hinge shaft 50 in the long limiting hole 41, the front and rear positions of the lid 10 change synchronously, thereby controlling the compression amount of the elastic buffer block 30, which can prevent the lid 10 from jumping due to insufficient buffering during the closing process, and improve the comfort of use.

[0079] The above embodiments are the preferred implementation of the present application, in addition to this, the present application can be implemented in other ways, without departing from the technical scheme concept, any obvious replacement within the protection scope of the present application.
