[0029] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0030] Please refer to Figures 1 to 6 As shown, an embodiment of the present invention provides a rice washing and draining system for rice preparation, including:

[0031] Inner pot body 1; water passing sieve holes 2 provided at the lower part of the inner pot body 1; drainage housing 4 wrapped around the periphery of the inner pot body 1; drainage port 401 provided on the drainage housing 4; washing cavity peripheral wall structure 301 provided at the bottom of the inner pot body 1;

[0032] Sealing chassis 3 connected to the drainage housing 4 and located below the washing cavity peripheral wall structure 301; the drainage housing 4 is used to drive the sealing chassis 3 to move up and down;

[0033] Pot body baffle structure 302 fixedly provided at the lower part of the inner pot body 1 and located inside the washing cavity peripheral wall structure 301;

[0034] Rotating disk 303 provided on the structure of the sealing chassis 3;

[0035] The turntable baffle structure 305 installed on the turntable 303; the turntable drive mechanism 304 for driving the rotation of the turntable 303; the turntable baffle structure 305 rotates relative to the pot body baffle structure 302 under the drive of the turntable drive mechanism 304.

[0036] The rice washing and draining system for rice preparation provided by the embodiment of the present invention, compared with the prior art, the rice washing and draining system for rice preparation involved in the embodiment of the present invention includes: the inner pot body 1; the water-passing sieve holes 2 provided at the lower part of the inner pot body 1; the drainage housing 4 wrapped around the outer periphery of the inner pot body 1; the drainage port 401 provided on the drainage housing 4; the rice washing cavity peripheral wall structure 301 provided at the bottom of the inner pot body 1; the sealing chassis 3 connected to the drainage housing 4 and located below the rice washing cavity peripheral wall structure 301; the drainage housing 4 is used to drive the sealing chassis 3 to move up and down; the pot body baffle structure 302 fixedly provided at the lower part of the inner pot body 1 and located inside the rice washing cavity peripheral wall structure 301; the turntable 303 provided on the sealing chassis 3 structure; the turntable baffle structure 305 installed on the turntable 303; the turntable drive mechanism 304 for driving the rotation of the turntable 303; the turntable baffle structure 305 rotates relative to the pot body baffle structure 302 under the drive of the turntable drive mechanism 304. Among them, a stir water cavity with variable volume is formed between the pot body baffle structure 302, the turntable baffle structure 305, the turntable 303, the bottom of the inner pot body 1, and the rice washing cavity peripheral wall structure 301. The stir water cavity with an increased volume sucks the rice washing water from the inner pot body 1 through the water-passing sieve holes 2 due to the negative pressure effect. The rice washing water in the stir water cavity with a decreased volume is injected into the inner pot body 1 through the water-passing sieve holes 2. The rice washing water in the inner pot body 1 can fully and violently wash the rice grains during the process of entering or flowing out of the inner pot body 1 through the water-passing sieve holes 2. Thus, the rice grains can be washed in the inner pot body 1 without manual cleaning, saving the intermediate step of transferring the washed rice grains to the inner pot body 1 during the rice preparation process. Moreover, since the drainage housing 4 can drive the sealing chassis 3 to move up and down, when the sealing chassis 3 abuts and fits against the bottom of the rice washing cavity peripheral wall structure 301, the rice washing water in the rice washing cavity peripheral wall structure 301 is sealed in the cavity and cannot be discharged. When the sealing chassis 3 moves downward, there is a gap between the sealing chassis 3 and the bottom of the rice washing cavity peripheral wall structure 301, and the rice washing water flows out from this gap into the drainage housing 4 and flows out of the pot body through the drainage port 401. The rice washing and draining system for rice preparation involved in the embodiment of the present invention, compared with the prior art, can realize the coherent progress of rice washing, draining, and steaming and cooking rice, saving labor and time costs, and significantly improving the automation degree and steaming and cooking efficiency of the rice preparation device.

[0037] Specifically, in the embodiment of the present invention, the drainage housing 4 drives the sealing chassis 3 to move up and down as follows: A rotating ring 5 is provided at the upper part of the pot body, and the inner side of the rotating ring 5 is an internal thread structure 501; an external thread structure 402 is provided on the outer side of the drainage housing 4 and is matched with the internal thread structure 501 of the rotating ring 5; the rotating ring 5 is driven by a rotating ring drive mechanism 6 to rotate, and the drainage housing 4 is in transmission cooperation with the rotating ring 5 to move up and down, thereby driving the sealing chassis 3 to move up and down.

[0038] Specifically, in the embodiment of the present invention, the external thread structure 402 is provided on the outer side of the drainage housing 4 as follows: A heat insulation ring 7 is provided above the drainage housing 4, and the external thread structure 402 is provided on the outer wall of the heat insulation ring 7.

[0039] Specifically, in the embodiment of the present invention, a rotation limiting rod 8 is connected to the heat insulation ring 7 and is used to limit the circumferential rotation of the heat insulation ring 7; the position of the rotation limiting rod 8 is relatively fixed with respect to the position of the pot body.

[0040] Specifically, in the embodiment of the present invention, the rotating ring drive mechanism 6 drives the rotating ring 5 to rotate as follows: A toothed ring structure is provided on the outer wall of the rotating ring 5; the gear on the output shaft of the rotating ring drive mechanism 6 is in transmission cooperation with the toothed ring structure.

[0041] Specifically, in the embodiment of the present invention, the heat insulation ring 7 includes: a heat insulation main body; a flange structure provided at the bottom of the heat insulation main body; a limiting hole provided on the flange structure and used to cooperate with the rotation limiting rod 8; the external thread structure 402 is specifically provided on the heat insulation main body.

[0042] Specifically, in the embodiment of the present invention, a limiting convex ring is provided at the bottom of the rotation limiting rod 8; the diameter of the limiting convex ring is larger than the diameter of the limiting hole.

[0043] Specifically, in the embodiment of the present invention, the turntable drive mechanism 304 includes: a turntable motor provided at the bottom of the turntable 303 and used to drive the turntable 303 to rotate; a rotating bearing provided at the bottom of the turntable 303.

[0044] Specifically, in the embodiment of the present invention, the pot body baffle structure 302 includes: a rotating cylinder 306 provided at the center of the lower part of the inner pot 1; a first baffle fixedly installed on the rotating cylinder 306; a second baffle fixedly installed on the rotating cylinder 306; the turntable baffle structure 305 includes: a third baffle fixedly provided on the turntable 303; a fourth baffle fixedly provided on the turntable 303.

[0045] Specifically, in the embodiments of the present invention, the first baffle and the second baffle are located on the same straight line; the third baffle and the fourth baffle are located on the same straight line.

[0046] Among them, when the turntable driving mechanism 304 drives the turntable 303 to rotate, the third baffle and the fourth baffle on the turntable 303 rotate with the turntable 303, and the first baffle and the second baffle on the pot body baffle structure 302 remain stationary. Among them, the volume of the first cavity formed between the first baffle, the third baffle, the bottom of the inner pot 1 of the pot, and the peripheral wall structure 301 of the rice cavity will show a negatively correlated change with the volume of the second cavity formed between the second baffle, the third baffle, the bottom of the inner pot 1 of the pot, and the peripheral wall structure 301 of the rice cavity; the volume of the third cavity formed between the first baffle, the fourth baffle, the bottom of the inner pot 1 of the pot, and the peripheral wall structure 301 of the rice cavity will also show a negatively correlated change with the volume change of the fourth cavity formed between the second baffle, the fourth baffle, the bottom of the inner pot 1 of the pot, and the peripheral wall structure 301 of the rice cavity. Thus, when the volume of the first cavity increases and the volume of the second cavity decreases, the washing rice water in the first cavity enters the inner pot of the pot through the water-passing sieve holes to wash the rice grains. The volume of the second cavity decreases, and due to negative pressure, the washing rice water is sucked into the inner pot of the pot through the water-passing sieve holes 2. The washing rice water in the inner pot of the pot can thoroughly wash the rice grains violently when entering or flowing out of the inner pot of the pot through the water-passing sieve holes 2. Thus, the washing of the rice grains in the inner pot of the pot can be realized without manual cleaning, eliminating the intermediate step of transferring the washed rice grains to the inner pot of the pot during the rice preparation process, realizing the coherent progress of washing rice and steaming and cooking rice, and significantly improving the automation degree and the steaming and cooking efficiency of the rice preparation device.

[0047] To further elaborate, the turntable is specifically arranged on the sealed chassis. The rotating ring driving mechanism 6 drives the rotating ring 5 to rotate. The inner part of the rotating ring 5 is provided with an internal thread structure 501, and the outer side of the drainage housing 4 is provided with an external thread structure 402. When the internal thread structure 501 rotates circumferentially, the external thread structure 402 cooperates with the internal thread structure 501 to drive the drainage housing 4 to move up and down. That is, the drainage housing 4 moves vertically under the rotation of the rotating ring 5. When the sealed chassis at the bottom of the drainage housing 4 fits against the bottom of the peripheral wall structure 301 of the rice washing cavity, the washing rice water in the rice washing cavity cannot be drained. When the rotating ring 5 rotates, the external thread structure 402 on the drainage housing 4 moves downward under the rotation of the internal thread structure 501, driving the sealed chassis to move downward away from the bottom of the peripheral wall structure 301 of the rice washing cavity. Thus, the washing rice water in the rice washing cavity can flow out from the gap between the peripheral wall structure 301 of the rice washing cavity and the sealed chassis into the drainage housing 4, and then flow out of the drainage housing 4 from the drainage port 401 at the bottom of the drainage housing 4 to the outside of the pot. Thus, the coherent drainage operation can be realized inside the pot after washing the rice, saving labor and time costs, and significantly improving the automation degree of the rice preparation device.

[0048] As described above, the rice washing and draining system for rice preparation according to the embodiments of the present invention, compared with the prior art, can realize the coherent progress of rice washing, draining and steaming / cooking rice, greatly saving labor and time costs, significantly improving the automation degree and steaming / cooking efficiency of the rice preparation device, and bringing great convenience to users.

[0049] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
