Description

Technical Field

[0001] This utility model relates to the field of rice cookers, specifically an anti-overflow lid structure for a rice cooker. Background Technology

[0002] Existing rice cooker structures, as shown in Chinese patent document, application number: 201621131123.X (plug-in type), mainly disclose a cooker body, a lid, an intelligent circuit, and a heating element. The cooker body has a cavity containing an inner pot and a steamer that can be installed inside the inner pot. The lid is connected to the top of the cooker body via a hinge structure. During the cooking process, the vigorously boiling rice water or foam can easily overflow from the venting structure on the lid, increasing the user's cleaning burden. Therefore, some rice cookers may have an anti-overflow cover at the bottom of the lid. However, the anti-overflow cover is generally fixed to the lid and cannot be removed. After long-term use, the back of the anti-overflow cover can easily accumulate dirt and bacteria, thus affecting the hygiene and safety of the cooked rice. Therefore, the applicant has improved and perfected the existing structure to solve the above problems and provide consumers with a choice to use. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See Figures 1 to 5 As shown, a rice cooker anti-overflow lid structure includes a rice cooker body 1 and a lid 2. The rice cooker body 1 has an inner pot 11 inside. The bottom of the lid 2 has an anti-overflow lid 3 adapted to fit the opening of the inner pot 11. The anti-overflow lid 3 has multiple anti-overflow through holes 301 evenly distributed on it. The bottom of the lid has a bolt 4 coaxially arranged with the inner pot 11. The center of the anti-overflow lid 3 has a central through hole 302 that passes through the bolt 4. After the bolt 4 is tightened with a hand nut 5, the anti-overflow lid 3 is detachably and securely connected to the lid 2.

[0023] This rice cooker can prevent overflow by using the anti-overflow cover 3 installed on the lid 2. Moreover, the anti-overflow cover 3 can be removed and cleaned simply by loosening the hand nut 5 without any tools, ensuring that the anti-overflow cover 3 is clean and hygienic and preventing dirt and bacteria from accumulating on the back side of the anti-overflow cover 3.

[0024] A washer nut 6 is also fitted onto the bolt 4. The washer nut 6 abuts against the overflow cover 3 and the bottom of the cover, and the overflow cover 3 has a first gap H1 between the washer nut 6 and the bottom of the cover. When the nut 5 is tightened by hand, the washer nut 6 can act as a spacer, and the first gap H1 formed by the spacer nut 6 serves as an overflow prevention function.

[0025] The hand-tightening nut 5 includes a nut body 51, which has a threaded hole 501 that mates with the bolt 4. One end of the nut body 51 is provided with a tightening ring 52, and the side surface of the tightening ring 52 is provided with anti-slip texture 521. The anti-slip texture 521 can prevent the user from slipping when tightening the hand-tightening nut 5, so that the user can tighten or loosen the hand-tightening nut 5 without the need for tools, and can operate it by hand.

[0026] The pot lid 2 includes a top cover 21 and a bottom cover 22 connected to the bottom of the top cover 21. The bottom cover 22 has a bolt hole 221. The bolt 4 passes through the bolt hole 221 and its head 41 is limited to the upper side of the bottom cover 22. The structure is simple. During installation, the bolt 4 only needs to be screwed into the bolt hole 221 to complete the fixation.

[0027] The bottom of the pot lid 2 is provided with several support pads 15 corresponding to the edge of the anti-overflow lid 3. The anti-overflow lid 3 abuts or rests against the several support pads 15. The support of the several support pads 15 ensures a stable first gap H1 between the anti-overflow lid 3 and the pot lid 2. During assembly, the upper part of the support pad 15 is provided with an undercut head 151, and the bottom cover 22 is provided with an undercut hole that cooperates with the undercut head 151. The support pad 15 is fastened to the bottom of the lid.

[0028] It also includes a sealing ring 7, which is fixedly connected to the bottom of the lid 2 by a fastening ring 8 and is arranged around the periphery of the anti-overflow cover 3. The anti-overflow cover 3 and the sealing ring 7 are spaced apart from each other. When the lid 2 is closed, the sealing ring 7 seals against the rim of the inner pot 11. The sealing ring 7 can prevent rice water or foam from overflowing out of the rice cooker or onto the top surface of the rice cooker body 1 through the gap between the lid 2 and the inner pot 11.

[0029] One side of the lid 2 is connected to the rice cooker body 1 by a hinge structure 9. A handle 14 is provided on the opposite side of the lid 2. The lid 2 can be opened by flipping it with the handle 14, which makes the operation easier. Compared with the whole disassembly, it is not necessary to move the lid 2 when opening or closing the lid, which reduces the pressure.

[0030] A baffle plate 71 extends downward from the sealing ring 7 near the hinge structure 9. The baffle plate 71 is placed inside the opening of the inner pot 11 after the lid 2 is closed. When the lid 2 is flipped open, the condensate on the surface of the anti-overflow lid 3 will flow downward naturally. The baffle plate 71 can intercept all the condensate in the sealing ring 7 for collection, preventing the condensate from flowing out of the lid 2 and contacting the hinge structure 9, which could cause the hinge structure 9 to rust easily. When the lid 2 is closed, the water in the sealing ring 7 can flow back into the inner pot 11 for the user to clean.

[0031] The inner lid 2 is also provided with a heat preservation plate 23, which is closely attached to or close to the upper side of the bottom cover 22, and the heat preservation plate 23 is provided with a spiral heat preservation strip 231; the heat preservation plate 23 can heat the bottom cover 22 during the cooking process, so that the air in the upper layer of the rice cooker can maintain the temperature, and can also keep the rice warm after cooking.

[0032] The lid 2 is provided with an exhaust channel 201 that connects the inner gap H1 with the outside air; the high-temperature steam generated during cooking can be discharged through the exhaust channel 201, allowing the rice cooker to release pressure.

[0033] The rice cooker body 1 includes an outer shell 10, an inner pot 11 placed inside the outer shell 10, a heating element 12 connected to the bottom surface of the inner pot 11, and a steamer 13 that can be placed inside the inner pot 11. The steamer 13 has a through hole 131 that connects to the inner cavity of the inner pot 11, and a second gap H2 is left between the bottom of the steamer 13 and the bottom of the inner pot 11. This structure can facilitate the cooking of rice cooked in a steamer. Through intelligent control, the cooking of rice cooked in a steamer can be achieved, and rice water can also be produced.

[0034] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
