Description

Technical Field

[0001] The invention relates to the field of kitchen appliances, in particular to a household automatic rice taking and washing machine. Background Art

[0002] Rice is rich in nutrients necessary for the human body and is one of the main foods of the Chinese people. At present, the rice, sorghum rice, millet, etc. sold in supermarkets and grain and oil stores have bran attachments, sand and other tiny particles on their surfaces. Before cooking, you need to wash the rice, which is also called washing rice. In modern family kitchens, people often wash rice by hand, which requires them to touch the water with their hands to rub the rice. During the repeated water-changing and washing process, rice grains are easy to stick to the washing utensils or between fingers. The impurities found need to be deliberately removed, and it is difficult to avoid slipping through the net. It not only hurts the hands, but is also very troublesome, time-consuming, labor-intensive, and inefficient, which brings troubles and inconveniences to people who often cook in their family kitchens. With the increasingly fierce social competition, people's pace of life is getting faster and faster. After a tiring day, when they return home, they want to rest but are afraid of delaying cooking, so they bite the bullet and start washing rice and pots again. Even if you use a rice cooker with a reservation function, you still need to put the washed rice and water into the rice cooker in advance. If the soaking time is too long, a nutrient called riboflavin in the rice will be lost in large quantities, and protein, fat, etc. will also be lost to some extent. In addition, a large number of bacteria will breed, and the cooked rice will not taste good. In the deep processing of food with rice as raw material, washing rice is the first step. At present, traditional rice washing devices use tools to stir and wash, which is not only labor-intensive, but also has poor cleaning effect. At the same time, when using tools to stir and wash, it is difficult to control the force, which greatly damages the integrity of the rice grains and seriously loses nutrients.

Initially, the first circulation pipeline 310 is located above the filter funnel 30, and the present invention is in the circulation rice washing mode. Initially, the lower cover plate 42 covers the bottom end surface of the separation cylinder 41. Initially, the valve 3112 covers the bottom end surface of the second drain port 3111.

[0044] (2) After the control panel 16 controls the rice delivery fan 60 to start, the rice grains accumulated in the rice inlet 6110 are first transported to the filter funnel 30 or the guide funnel 11 along the second rice delivery pipe 611, the third rice delivery pipe 612 and the fourth rice delivery pipe 613. Since the rice outlet 50 of the rice storage bin 5 is connected to the rice inlet 6110, the rice grains stored in the rice storage bin 5 are continuously replenished in the direction of the rice outlet 50 under the blowing of the rice delivery fan 60, so as to achieve air washing and rice delivery. When the rice delivery fan 60 starts and reaches the preset time, the control panel 16 controls the rice delivery fan 60 to turn off, so as to accurately control the amount of rice delivered. The rice grains after passing through the second rice delivery pipe 611, the third rice delivery pipe 612 and the fourth rice delivery pipe 613 enter the filter funnel 30 or the guide funnel 11 under the blocking of the baffle 13 and the second baffle plate 12 and the receiving plate 301. At this time, the control panel 16 controls the solenoid valve 10 to open, so that the external tap water first enters the water inlet pipe 312, and the tap water enters the second circulation pipe 311 under the boosting effect of the booster 8. The tap water after entering the second circulation pipe 311 passes through the first circulation pipe 310 and is sprayed to the guide funnel 11. In the funnel 11 and the filter funnel 30, the tap water drives the rice grains in the guide funnel 11 or the filter funnel 30 to flow to the bottom of the filter funnel 30. Since the bottom of the filter funnel 30 is connected to the second circulation pipeline 311 through the interface 3110, the rice grains enter the second circulation pipeline 311 under the drive of the tap water. The rice grains flow to the first circulation pipeline 310 along the second circulation pipeline 311 under the action of the supercharger 8, and then flow to the guide funnel 11 and the filter funnel 30 from the first circulation pipeline 310, and the rice washing cycle is realized by analogy. With the continuous entry of tap water, the filter funnel 30 is gradually filled with rice water for washing the rice grains. At this time, the rice water will carry impurities or other floating objects. When the water level of the rice water reaches the position of the drain port 300, the rice water enters the bottom of the body 1 through the drain port 300. Since the drain pipe 7 is connected to the body 1, the rice water is discharged from the base 2 through the drain pipe 7, and the rice water is automatically discharged.

[0045] (3) When the preset cyclic rice washing time of the control panel 16 is reached, the control panel 16 controls the battery valve 10 to close, and then rotates the motor 320, which drives the first gear 322 to rotate forward, and the first gear 322 simultaneously drives the second gear 323 to rotate, thereby rotating the first circulation pipeline 310 from the top of the filter funnel 30 to the top receiving port 40 of the separation cylinder 41. At this time, the rotating motor 320 stops, and finally the battery valve 10 is opened. The rice grains fully filtered by the circulation filtering device 3 fall into the separation cylinder 41 along with the rice water, and the rice water and the rice grains are separated in the separation cylinder 41. The rice water flows into the body 1 through the filter hole 410 of the separation cylinder 41, and is then discharged by the drain pipe 7, while the rice grains are received on the lower cover plate 42. After the preset time for the rice water and rice grains to separate, the control panel 16 controls the electromagnetic valve 10 to close, and controls the driving motor 43 to move at the same time, and the driving motor 43 drives the lower cover plate 42 to rotate in the body 1, and the rice grains supported on the lower cover plate 42 can fall into the electric rice cooker, realizing automatic rice falling. The control panel 16 controls the battery valve 10 to open again, and the water consumption counted by the flow meter 9 is converted into an electrical signal to feed back to the control panel 16. According to the requirements of different rice varieties, rice quantities and taste, the control panel 16 automatically and accurately proportions the rice water consumption, and then the battery valve 10 is closed, realizing automatic water distribution.

[0046] (4) The control panel 16 controls the rotating motor 320 to move again. The rotating motor 320 drives the first gear 322 to reverse. The first gear 322 simultaneously drives the second gear 323 to rotate, thereby rotating the first circulation pipe 310 from the top receiving port 40 of the separation cylinder 41 to the top of the filter funnel 30, thereby resetting the first circulation pipe 310. After the resetting is completed, the rotating motor 320 stops.

[0047] (5) The control panel 16 controls the valve motor 3113 to rotate forward, and the excess water flows into the machine body 1 through the second drain port 3111 and is then discharged from the drain pipe 7. After a preset drainage time, the control panel 16 controls the valve motor 3113 to rotate reversely.

[0048] In summary, the present invention can automatically clean rice grains, and the rice grains after cleaning automatically enter the separation device 4 for rice and water separation, and finally automatically and accurately proportion the rice and water consumption according to different rice amounts, and no rice grains will remain in the process. The present invention integrates multiple functions of rice storage, rice taking, rice washing, and water-rice ratio, and can be fully automatically quantified. It has a high degree of automation and is easy to use. When the user needs to clean the rice grains, he only needs to operate the control panel 16. The whole process is clean and fast, saving time and effort, and improving the user's experience. The circulating filter device 3 adopts pipeline type rice washing, and the water and rice are mixed and flow-washed, which effectively removes dirt and reduces the water consumption while improving the accuracy of rice washing.

It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
