Description

Technical Field

[0001] This utility model relates to the field of rice cookers, specifically a sealing ring assembly structure for a rice cooker. Background Technology

[0002] Existing rice cooker structures, such as the plug-in type rice cooker described in Chinese patent document application number 201621131123.X, 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 placed 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 inner pot. Therefore, some rice cookers are equipped with a sealing ring on the lid to seal the gap between the lid and the inner pot. During assembly, a ring is used to press and fix the sealing ring. However, in the production process, this ring is generally produced by injection molding of a whole circle. As a result, the mold can only be manufactured according to the size of the ring. The hollow part of the ring leads to wasted mold space, which greatly reduces production efficiency. Moreover, the produced ring occupies packaging space during packaging and transportation, which increases transportation costs. Therefore, the applicant improves and perfects the existing structure to solve the above problems and make it available to consumers. 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 6 As shown, a sealing ring assembly structure for a rice cooker includes a rice cooker body 1 and a lid 2. The rice cooker body 1 has an inner pot 11 inside. The bottom 21 of the lid 2 is provided with a sealing ring 3 that fits into the opening of the inner pot 11. It also includes four arc-shaped parts 41. Each arc-shaped part 41 has a tenon 42 at one end and a mortise 43 at the other end. Two or more arc-shaped parts 41 are spliced ​​together by the tenon and mortise structure to form a ring 4. The ring 4 is fastened to the lid 2 to fix the sealing ring 3 to the bottom 21 of the lid.

[0023] The sealing ring 3 on this rice cooker is fixed to the lid 2 using a circular ring 4, which is easy to install. The circular ring 4 is made up of several arc parts 41. In production, the mold cavity of the arc parts 41 is arranged in a matrix, which can make full use of the mold space and reduce the waste of mold space. More circular rings 4 than usual can be produced at the same time under the same mold size, or the size of the mold can be reduced. In terms of transportation, the arc component 41 can be disassembled and packaged for transportation before the ring 4 is assembled, which can save space and further reduce transportation costs. In terms of installation, multiple arc components 41 can be quickly spliced ​​together through mortise and tenon structure, which can improve production efficiency and reduce the impact of additional splicing steps on production efficiency.

[0024] Each arc component 41 is provided with several connecting holes 411. The bottom 21 of the pot lid 2 is provided with through holes 201 corresponding to the positions of the connecting holes 411. The fastening unit passes through the through holes 201 and the connecting holes 411 to make the entire ring 4 fastened to the pot lid 2. During installation, first connect the four arc-shaped parts 41 together using a mortise and tenon structure to form a ring 4. Then, fit the sealing ring 3 onto the ring 4 and place the ring 4 on the bottom 21 of the lid 2, aligning the connecting hole 411 with the through hole 201. Then, use screws or other fastening units to tighten the through hole 201 and the connecting hole 411 to complete the fixing of the ring 4. After installation, the sealing ring 3 is clamped between the ring 4 and the bottom 21 of the lid.

[0025] Each arc component 41 has two or more positioning protrusions 412 extending along its length. The bottom 21 of the lid 2 has positioning holes 202 corresponding to the positioning protrusions 412. By inserting the positioning protrusions 412 into the positioning holes 202, the entire ring 4 is positioned on the bottom 21. With the cooperation of multiple positioning protrusions 412 and multiple positioning holes 202, the ring 4 can be quickly positioned when placed on the bottom 21 of the lid 2. The ring 4 will not slide or shift during the screw-in process.

[0026] The tenon 42 and mortise 43 are both arranged along the thickness of the arc member 41. Adjacent tenons 42 and mortises 43 are spliced ​​together by the vertical translation of the arc member 41. The tenons 42 and mortises 43 have a circular or dovetail structure; the structure is simple and can achieve rapid splicing.

[0027] The inner side of the annular ring 4 is provided with a connecting protrusion 44; the sealing ring 3 includes a sealing body 31 sleeved on the connecting protrusion 44, the sealing body 31 is pressed between the bottom of the cover 21 and the connecting protrusion 44, and the lower part of the sealing body 31 extends a sealing lip 32, which elastically abuts against the inner liner 11.

[0028] The upper surface of the connecting convex ring 44 is provided with a limiting groove 441, and the inner side of the sealing body 31 extends with an anti-detachment flange 33 that is inserted into the limiting groove 441. Although the sealing body 31 is clamped between the connecting convex ring 44 and the cover bottom 21, the sealing ring 3 is prone to loosening when pulled. Therefore, through the cooperation of the anti-detachment flange 33 and the limiting groove 441, when the sealing ring 3 is pulled, the anti-detachment flange 33 can be stuck in the limiting groove 441 to prevent the sealing ring 3 from loosening.

[0029] One or more sealing ribs 34 extend from the mating surface of the sealing body 31 that contacts the cover bottom 21. The sealing ribs 34 elastically abut against the cover bottom 21. The sealing ribs 34 can seal the gap between the annular ring 4 and the cover bottom 21.

[0030] The bottom 21 of the pot lid 2 is connected to the opening of the inner pot 11 with an anti-overflow cover 5. The anti-overflow cover 5 has multiple anti-overflow through holes 501 evenly distributed on it. The anti-overflow cover 5 and the pot lid 2 are detachably fitted together. The sealing ring 3 is arranged around the outer periphery of the anti-overflow cover 5. The anti-overflow cover 5 can play the role of preventing overflow.

[0031] 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 gap H 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 in a steamer. Through intelligent control, the cooking of rice in a steamer can be achieved, and rice water can also be produced.
