Description

Technical Field

[0001] This utility model relates to the field of rice cooker inner pot technology, specifically a rice cooker inner pot flipping structure and a rice cooker. Background Technology

[0002] Rice cookers are common cooking appliances used to cook rice. Before cooking rice, you usually need to wash the raw rice and put it into the rice cooker with an appropriate amount of water. After closing the rice cooker, you can start cooking and make plump, cooked rice.

[0003] Normally, when washing rice, people take the inner pot of the rice cooker to the sink, fill it with water, and then wash the raw rice inside. After the rice is washed, they pour out the rice-washing water from the inner pot. At this point, they need to cover the edge of the inner pot with their hands and let the rice-washing water flow out through the gaps between their fingers. However, they need to control the gaps between their fingers to prevent the raw rice from flowing away with the rice-washing water. This method of washing rice is very common, but it is inconvenient for people. Moreover, when pouring out the rice-washing water, it is easy for raw rice to flow out as well. The skill with which people control the gaps between their fingers directly affects the amount of raw rice that flows out. This method is not convenient for people to wash rice.

[0004] To address the above shortcomings, we need to develop a rice cooker inner pot flipping structure and a rice cooker that meets the needs of a wide range of users. Utility Model Content

[0005] To address the aforementioned problems with existing rice washing methods, such as rice and water easily spilling out of the inner pot, resulting in rice waste and inconvenience, the technical solution adopted by this utility model is as follows:

[0006] A rice cooker inner pot flipping structure includes a first inner pot and a second inner pot that can be placed inside the rice cooker. The first inner pot has a receiving cavity for accommodating the second inner pot, and the second inner pot has a rice material cavity for accommodating rice. The second inner pot is hinged to the inner side wall of the receiving cavity. The bottom of the rice material cavity has a plurality of sieve holes for rice washing water to flow out, and the rice material cavity is connected to the receiving cavity through the sieve holes.

[0007] As described above, in a rice cooker inner pot flipping structure, the first inner pot is provided with a hinge protrusion extending toward the second inner pot, and the second inner pot is provided with a hinge recess adapted to the hinge protrusion. The hinge protrusion is located near the top opening of the receiving cavity, and the hinge recess is located near the top opening of the rice feed cavity.

[0008] As described above, in a rice cooker inner pot flipping structure, the hinge protrusion is detachably connected to the inner wall of the first inner pot, or the hinge protrusion is integrally formed on the inner wall of the first inner pot.

[0009] The hinge recess can be detachably connected to the outer side wall of the second inner liner, or the hinge protrusion can be integrally formed on the inner side wall of the first inner liner.

[0010] In the rice cooker inner pot flipping structure described above, the hinge recess extends toward the bottom of the second inner pot to form a recessed inlet / outlet channel for the hinge protrusion to extend into or retract from the recess, and the channel width a of the recessed inlet / outlet channel is greater than the outer diameter b of the hinge protrusion.

[0011] As described above, in a rice cooker inner pot flipping structure, one of the first inner pot and the second inner pot is provided with an elastically extendable hinge protrusion, and the other of the first inner pot and the second inner pot is provided with a hinge recess adapted to the hinge protrusion. The hinge protrusion is located on the outer side wall of the second inner pot near the top opening, and the hinge recess is located on the inner side wall of the first inner pot near the top opening.

[0012] As described above, in a rice cooker inner pot flipping structure, two hinge protrusions are coaxially and symmetrically arranged between the first inner pot and the second inner pot, and the hinge protrusions can elastically extend or elastically retract along the hinge rotation axis.

[0013] As described above, the inner pot flipping structure of a rice cooker includes a telescopic protrusion for movable extension and a telescopic orientation structure for restricting the directional movement of the telescopic protrusion. An elastic deformation member for elastic ejection is installed between the telescopic protrusion and the telescopic orientation structure. The hinge recess has a through hole for disassembly and assembly along the extension direction.

[0014] In the rice cooker inner pot flipping structure described above, the maximum rotation radius c of the second inner pot is smaller than the minimum radius d of the accommodating cavity.

[0015] As described above, in a rice cooker inner pot flipping structure, a screen for separating and diverting rice and water is laid near the screen holes in the rice feed cavity. The screen holes are located within the area covered by the screen, and the screen is made of a flexible material.

[0016] A rice cooker, including the aforementioned rice cooker inner pot flipping structure.

[0017] The beneficial effects of this utility model are as follows:

[0018] The inner pot of this rice cooker adopts a double-layer structure with inner and outer layers. The second inner pot is hinged inside the first inner pot. When the user needs to pour out the rice water after washing the rice, the first inner pot is tilted to pour out the rice water. The washed rice water flows out through the sieve holes into the first inner pot, while the raw rice does not pass through the sieve holes. The second inner pot, where the raw rice is located, will not tilt with the tilt of the first inner pot due to the hinge and its own center of gravity. That is, when the rice water is poured out from the side of the first inner pot, the second inner pot remains in a flat state, which can keep the washed raw rice in the rice cavity of the second inner pot. This achieves the effect of separating the raw rice from the flow without the need for a person to cover it. When cooking, the first inner pot is filled with water as usual, and the second inner pot can be heated and cooked by the first inner pot as a steaming basket, realizing the basic function of cooking rice.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1:

[0032] like Figures 1 to 10 The rice cooker inner pot flipping structure shown includes a first inner pot 1 and a second inner pot 2 that can be placed inside the rice cooker. The first inner pot 1 has a receiving cavity 11 for accommodating the second inner pot 2, and the second inner pot 2 has a rice material cavity 21 for accommodating rice. The second inner pot 2 is hinged to the inner wall of the receiving cavity 11. The bottom of the rice material cavity 21 is provided with a plurality of sieve holes 22 for rice water to flow out, and the rice material cavity 21 is connected to the receiving cavity 11 through the sieve holes 22.

[0033] Specifically, in this embodiment, the first inner pot 1 and the second inner pot 2 are the layered structures inside the rice cooker, consisting of inner and outer layers. The first inner pot 1 is the outer part of the layered structure, and the second inner pot 2 is the inner part of the layered structure. The first inner pot 1 can be normally placed into and removed from the corresponding rice cooker. Compared with the traditional rice cooker inner pot, the first inner pot 1 has an additional hinge structure inside for hinged to the second inner pot 2. The hinge structure is close to the top opening of the first inner pot 1. The outer diameter of the second inner pot 2 is smaller than the inner diameter of the first inner pot 1. The second inner pot 2 is placed into the first inner pot 1 and hinged to the inner wall of the receiving cavity 11 of the first inner pot 1. The hinge structure of the second inner pot 2 is located on the outside near the top opening. After the second inner pot 2 is installed in the first inner pot 1, its center of gravity is located in the middle of the bottom side, so that no matter how the first inner pot 1 moves, the second inner pot 2 can still be in a flat position with its center of gravity down and its opening up.

[0034] Specifically, in this embodiment, the second inner liner 2 is provided with a number of sieve holes 22 at the bottom. These sieve holes are used to allow the rice water after washing the raw rice to flow through. The aperture of the sieve holes 22 is preferably smaller than the outer diameter of a single grain of raw rice, so that the raw rice will not flow away with the rice water when it flows out. The sieve holes 22 play the role of keeping the raw rice in the rice chamber 21. Increasing the number of sieve holes 22 can speed up the flow of rice water and reduce the impact of raw rice clogging individual sieve holes 22 on the flow of rice water.

[0035] In use, the user places raw rice and water into the second inner tank 2, respectively. The raw rice is then washed in the rice chamber 21 of the second inner tank 2. After washing, the user tilts the first inner tank 1 to pour out the turbid rice water. The washed rice water flows through the sieve 22 back into the first inner tank 1 (e.g., ...). Figure 5(showing the direction of water flow), but at this time, the sieve hole 22 will retain the raw rice in the rice material cavity 21. The second inner pot 2 where the raw rice is located will not tilt with the tilt of the first inner pot 1 due to the hinge rotation and its own center of gravity. That is, when the washing water is poured out laterally after the first inner pot 1 tilts, the second inner pot 2 is still in a flat state, which can retain the washed raw rice in the rice material cavity 21 of the second inner pot 2, realizing the effect of separating raw rice and water. It achieves the effect of not needing to cover the edge of the inner pot to prevent the raw rice from flowing out. When cooking, the first inner pot 1 is cooked with an appropriate amount of water as usual. After the water in the first inner pot 1 is heated and boiled, it cooks the raw rice inside the second inner pot 2. The second inner pot 2 can be heated and cooked by the first inner pot 1 as a steaming cage, realizing the basic function of cooking rice.

[0036] Furthermore, in some preferred embodiments, such as Figure 5 The rice cooker inner pot flipping structure shown has a maximum rotation radius c of the second inner pot 2 that is smaller than the minimum radius d of the accommodating cavity 11. Specifically, in this embodiment, the maximum rotation radius c of the second inner pot 2 is the maximum rotational collision outer diameter when the second inner pot 2 flips around the hinge structure, and the minimum radius d of the accommodating cavity 11 is the inner diameter of the side wall of the accommodating cavity 11. When rotating, the side wall of the accommodating cavity 11 avoids the rotation range of the maximum rotation radius c, which can ensure the smooth movement of the second inner pot 2.

[0037] Furthermore, in some alternative embodiments, such as Figures 1 to 10 The rice cooker inner pot flipping structure shown has a limiting ear 12 extending from the top opening of the first inner pot 1 away from the center of the opening. Specifically, in this embodiment, the limiting ear 12 is a bent flange formed in the top opening of the first inner pot 1, which can limit the placement position of the first inner pot 1 when it is put into the rice cooker.

[0038] Furthermore, in some alternative embodiments, a rice cooker inner pot flipping structure can be applied inside the rice cooker product to facilitate user rice washing.

[0039] Example 2:

[0040] Based on Example 1, such as Figure 1 as well as Figures 3 to 6 The rice cooker inner pot flipping structure shown has a first inner pot 1 with a hinge protrusion 3 extending toward the second inner pot 2, and a second inner pot 2 with a hinge recess 4 adapted to the hinge protrusion 3. The hinge protrusion 3 is located near the top opening of the receiving cavity 11, and the hinge recess 4 is located near the top opening of the rice feed cavity 21.

[0041] Specifically, in this embodiment, the hinge protrusion 3 is disposed in the first inner liner 1, extending from the inner wall of the first inner liner 1 toward the hinge recess 4 of the second inner liner 2. The hinge recess 4 is disposed in the second inner liner 2, recessing from the outer wall of the second inner liner 2 toward the interior. During assembly, the hinge protrusion 3 extends into the hinge recess 4, allowing the second inner liner 2 to pivot relative to the first inner liner 1. Furthermore, the hinge recess 4 is located near the top opening of the rice feed cavity 21, ensuring that the center of gravity of the second inner liner 2 is located near the bottom of the rice feed cavity 21. The second inner liner 2, affected by the pivot rotation and its own center of gravity, will not tilt with the tilt of the first inner liner 1. That is, when the first inner liner 1 tilts and the rice water is poured out laterally, the second inner liner 2 remains in a flat position (e.g., ...). Figure 5 (As shown in the hinge posture), in order to better accommodate the second inner pot 2, the hinge protrusion 3 is located near the top opening of the accommodating cavity 11, so that the second inner pot 2 can be completely inserted into the accommodating cavity 11, and the top opening of the first inner pot 1 can be smoothly closed to form a sealed rice cooker interior.

[0042] Furthermore, in some alternative embodiments, the hinge protrusion 3 is detachably connected to the inner wall of the first inner liner 1, and the hinge recess 4 is detachably connected to the outer wall of the second inner liner 2. Specifically, in this embodiment, both the hinge protrusion 3 and the hinge recess 4 are detachably connected (such as by snap-fit ​​connection, screw connection, etc.). The detachable structure makes it convenient for users to replace parts when they are damaged.

[0043] Furthermore, in some optional embodiments, the hinge protrusion 3 is integrally formed on the inner wall of the first inner liner 1, and the hinge recess 4 is integrally formed on the inner wall of the second inner liner 2. Specifically, in this embodiment, the hinge protrusion 3 is formed and solidified together with the first inner liner 1 during production, and the hinge recess 4 is formed and solidified together with the second inner liner 2 during production, thereby enhancing the stability of the hinge structure and making it less prone to deformation and damage during long-term use.

[0044] Furthermore, in some alternative embodiments, the hinge protrusion 3 is detachably connected to the inner wall of the first inner liner 1, and the hinge protrusion 3 is integrally formed on the inner wall of the first inner liner 1.

[0045] Furthermore, in some alternative embodiments, the hinge protrusion 3 is integrally formed on the inner sidewall of the first inner liner 1, and the hinge recess 4 is detachably connected to the outer sidewall of the second inner liner 2.

[0046] Furthermore, in some alternative embodiments, such as Figure 4 and Figure 6 The rice cooker inner pot flipping structure shown has a hinged recess 4 extending toward the bottom of the second inner pot 2 to form a recessed inlet / outlet channel 41 for the hinged protrusion 3 to extend into or retract. The channel width a of the recessed inlet / outlet channel 41 is greater than the outer diameter b of the hinged protrusion 3.

[0047] Specifically, in this embodiment, the recessed access channel 41 is also a part that is recessed from the outer side wall of the second inner liner 2 toward the inside. Since the second inner liner 2 can achieve a flat position by relying on its own stable downward center of gravity, the recessed access channel 41 for installation or removal extends toward the bottom of the second inner liner 2, which can ensure simple installation and removal and prevent it from easily falling off during use, and can also facilitate cleaning.

[0048] Example 3:

[0049] Based on Example 1, such as Figure 2 as well as Figures 7 to 11 The rice cooker inner pot flipping structure shown has one of the first inner pot 1 and the second inner pot 2 having an elastically extendable hinge protrusion 3, and the other of the first inner pot 1 and the second inner pot 2 having a hinge recess 4 adapted to the hinge protrusion 3. The hinge protrusion 3 is located on the outer side wall of the second inner pot 2 near the top opening, and the hinge recess 4 is located on the inner side wall of the first inner pot 1 near the top opening.

[0050] Specifically, in this embodiment, the hinge protrusion 3 is installed in the first inner liner 1 or the second inner liner 2 using an elastically telescopic structure. When it needs to be installed, the assembler presses the hinge protrusion 3 in, so that the second inner liner 2 can be smoothly placed into the receiving cavity 11 and the hinge protrusion 3 is aligned with the hinge recess 4. After the assembler releases the hinge protrusion 3, the hinge protrusion 3 extends into the hinge recess 4 due to the elastic ejection effect. Installation can be carried out without the need to add an additional assembly clearance channel structure. When it needs to be removed, the assembler presses the hinge protrusion 3 in, so that the second inner liner 2 can be smoothly pulled out of the receiving cavity 11 and the hinge protrusion 3 disengages from the hinge recess 4. This achieves the effect of both installation and removal, and also avoids the situation where the second inner liner 2 accidentally comes out of the first inner liner 1 in extreme cases.

[0051] Furthermore, in some optional embodiments, the two hinge protrusions 3 are coaxially and symmetrically arranged between the first inner liner 1 and the second inner liner 2, and the hinge protrusions 3 can elastically extend or elastically retract along the hinge rotation axis. Specifically, in this embodiment, the symmetrical arrangement on both sides can enhance the stability and robustness of the hinge rotation, balance the rotational force, and make it more convenient for users to use.

[0052] Furthermore, in some alternative embodiments, such as Figures 7 to 11 The rice cooker inner pot flipping structure shown includes a hinge protrusion 3 comprising a telescopic protrusion 31 for movable extension and telescopic movement and a telescopic orientation structure 32 for restricting the directional movement of the telescopic protrusion 31. An elastic deformation member 33 for elastic ejection is installed between the telescopic protrusion 31 and the telescopic orientation structure 32. The hinge recess 4 has a through-hole 42 for disassembly and assembly along the extension direction.

[0053] Specifically, in this embodiment, the telescopic orientation structure 32 is a hollow recessed structure extending from the outer side wall of the second inner liner 2 toward the outside, the telescopic protrusion 31 is a protruding structure that can be moved and extended in the hollow recess of the telescopic orientation structure 32, the elastic deformation member 33 is preferably a spring or a spring sheet, and the disassembly and assembly through hole 42 is a through hole structure opened on the inner side of the hinge recess 4 so that the hinge recess 4 connects to the outer side of the first inner liner 1.

[0054] When installation is required, the assembler presses the telescopic protrusion 31 in, allowing it to avoid the outside of the hinge recess 4 and align it with the inside of the hinge recess 4. After the assembler releases the telescopic protrusion 31, it extends into the hinge recess 4 due to the elastic ejection of the elastic deformable member 33. Installation can be carried out without the need to add an additional assembly clearance channel structure. When removal is required, the assembler enters through the disassembly and assembly through hole 42 and presses the telescopic protrusion 31 in with a tool, allowing the second inner liner 2 to be smoothly pulled out of the receiving cavity 11 and the telescopic protrusion 31 to disengage from the hinge recess 4. This achieves the effect of both installation and removal, and also avoids the situation where the second inner liner 2 accidentally comes out of the first inner liner 1 in extreme cases, further facilitating disassembly, assembly, and use.

[0055] Example 4:

[0056] Based on any of the above embodiments, to prevent rice water sediment from clogging the sieve holes 22, such as Figures 3 to 6 The rice cooker inner pot flipping structure shown has a rice feed chamber 21 with a screen 5 for separating and diverting rice and water near the screen holes 22. The screen holes 22 are located within the area covered by the screen 5, and the screen 5 is made of flexible material.

[0057] Specifically, in this embodiment, the aperture of the sieve hole 22 is larger than the outer diameter of a single grain of raw rice. The sieve 5 is a thin-layer structure used to assist in sieving raw rice. The sieve 5 also has several small sieve holes, the aperture of which is smaller than that of the sieve hole 22. Since the wall thickness of the second inner liner 2 is relatively large, the rice water sediment is prone to sticking and clogging during the flow through the sieve hole 22. In addition, the rigidity and hardness of the second inner liner 2 are relatively large, making it difficult to clean. Therefore, the aperture of the sieve hole 22 needs to be increased to facilitate the flow of water and sediment. The step of sieving raw rice is handled by the sieve 5.

[0058] In use, the user places raw rice and water into the second inner tank 2, respectively. The raw rice is then washed in the rice chamber 21 of the second inner tank 2. After washing, the user tilts the first inner tank 1 to pour out the turbid rice water. The washed rice water passes through the sieve holes 22 on the sieve 5 and flows out into the first inner tank 1 (e.g., ...). Figure 5(showing the direction of water flow), but at this time the screen 5 will retain the raw rice in the rice chamber 21, achieving the effect of separating raw rice and water. Since the screen 5 is made of a flexible material (such as silicone, rubber, plastic, cloth thread, etc.), if there is rice water sediment clogging the screen 5, the screen 5 can be pulled out for front and back washing. It can be cleaned by rubbing and other methods to remove the residual rice water sediment, so that the screen 5 can be reused repeatedly.

[0059] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
