Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an automatic rice sharpener that automatically sharpens rice using water pressure from a water source such as a tap.

[Conventional technology] Before cooking rice, it is necessary to sharpen the rice, but in the past, the rice was stored in a container and the rice was polished manually while pouring water from a tap into the container. It is normal to be.

[Problem that the invention attempts to solve]

However, with this method, not only is the efficiency of rice polishing inefficient, but it is also a hassle to soak the rice in the water in the container.
This becomes an even more troublesome task, especially during periods when the water temperature is low, such as in the winter. This idea was developed in light of these problems, and the purpose is to provide an automatic rice sharpener that can automatically and efficiently sharpen rice without the need for manual labor. .

[Means for solving problems]

In order to solve the above-mentioned problems, this invention stores a rice container removably in a guide container that has a pit hole in the bottom and an outflow part in the upper part of the circumference.
A passage opening that can be opened and closed through which rice grains can pass is provided at the bottom of the rice receiving container, and an overflow section through which water can flow is provided at the top of the circumferential surface at a level that is the same as or higher than the outflow section. , a water passage is connected to the pit hole of the guide container almost perpendicular to the axial direction of the pit hole, one end of this water passage is connected to a water source, and the other end is similarly raised above the rice receiving container. It is opposed to the opening at the upper end of the rice receiving container.

[Effect]

Under normal conditions, water is stored at a certain level in the rice receiving container, guide container, and water passage. When sharpening rice, the rice receiving container is taken out from the guide container and the rice is stored in the rice receiving container with the passage port closed. Then, the rice receiving container is placed into the guide container again, and the passage port is opened. As a result, the rice grains in the rice receiving container fall through the passage hole and accumulate at the bottom of the guide container.

If you open the water source valve in this situation,
Water flows out due to the water pressure of the water source, and this water flows through the water passage and sequentially flows into the rice receiving container from above the rice receiving container. As water flows through the water passage, the rice grains accumulated at the bottom of the guide container are sequentially drawn into the water passage through the pit, and are returned to the rice receiving container through the water passage, and then the rice grains are returned to the pit from the passage opening. The rice then flows into the water passage and circulates in sequence, and this circulation removes foreign substances such as dust attached to the rice grains and gradually purifies them. In addition, as water flows into the rice receiving container from the water flow channel, the water level in the rice receiving container and guide container rises, causing the upper layer of water in the rice receiving container to collect dust and other particles separated from the rice grains. Together with the foreign matter, it sequentially overflows through the overflow section and outflow section and is discharged.

After the rice has been polished, the passage opening of the rice receiving container is closed. Then, the rice grains that flowed into the rice receiving container along with water from the water passage are captured in the rice receiving container one after another, only the water is discharged through the overflow part, and after a while all of the rice grains are stored in the rice receiving container. , close the water source valve and remove the rice container from the guide container.

Note that 38 is a battery for powering the water detection device 36 and dirt detection sensor 37.

Next, we will discuss the effect.

Normally, water supplied from the faucet 28 is stored at a constant water level H in the rice receiving container 8, the guide container 4, and the water passage 21. When sharpening rice, the cover 32 and the discharge pipe 26 are
is rotated to retreat from above the rice receiving container 8, and in this state, the rice receiving container 8 is taken out from the guide container 4,
Rice is stored in the rice receiving container 8 with the passage ports 14 closed. Then, the rice receiving container 8 is stored in the guide container 4 again, the inner tank 10 is rotated via the lever 17, and the passage opening 14 is opened in the cutout window 1 of the outer tank 9.
2. Open it facing the... As a result, the rice grains in the rice receiving container 8 pass through the passage port 14 into the guide container 4.
It falls to the bottom and accumulates. Thereafter, the discharge pipe 26 is rotated together with the cover 32 so that its lower end face faces the upper center of the rice receiving container 8, and in this state, the valve of the faucet 28 is opened. In response to this, water flows out from the faucet 28 under the water pressure of the water source, and this water flows through the water passage 21 and sequentially flows into the rice receiving container 8 from above the rice receiving container 8. As water flows through the water passage 21, the rice grains accumulated at the bottom of the guide container 4 are sequentially drawn into the water passage 21 through the pit 5, and sequentially flow through the delivery pipe 25 and the discharge pipe 26 to form the rice receiving container. The rice grains are returned to the rice grains 8 and flow into the water passage 21 again from the passage ports 14 through the pits 5 and circulated in sequence. Due to this circulation, foreign substances such as dust attached to the rice grains are peeled off. The rice is gradually purified.

In addition, as water flows into the rice receiving container 8 from the discharge pipe 26, the water level in the rice receiving container 8 and the guide container 4 rises, so that the water in the upper layer in the rice receiving container 8 is absorbed by the rice grains. Together with foreign substances such as dust peeled off from the outer container 1, the water sequentially overflows into the outer container 1 through the overflow section 16, the cutout windows 12, and the outflow section 6, and is discharged from the drain port 3. At this time, a portion of the water overflowing from the rice receiving container 8 flows through the detour path 35 and flows into the outer container 1. When water flows through the detour 35, it is detected by the water detection device 36, and in response to this detection, the dirt sensor 37 is activated, and the degree of contamination of the water flowing through the detour 35 is detected.

By the way, the water supplied from the faucet 28 to the water passage 21 is squeezed by the taper part 29 of the nozzle pipe 23 and spurts forcefully into the lower part of the pit 5, so that the rice grains are smoothly transferred from the pit 5 into the water passage 21. be drawn into. And this rice grain has a spiral protrusion 30
As a result, the rice grains and water are well stirred, and foreign substances such as dust attached to the rice grains are efficiently peeled off. In addition, the discharge pipe 2 of the water passage 21
The rice grains flowing into the rice receiving container 8 together with water from the rice container 6 hit the hemispherical head at the upper end of the support shaft 11 and are scattered, so that the entire rice is evenly washed.

Foreign matter such as dust separated from the rice grains floats on the upper water surface in the rice receiving container 8 and is discharged from the outer container 1 through the discharge port 3 together with the water on the water surface.

When the rice is polished, the dirt detection sensor 37 notifies you via a buzzer and a lamp (not shown), and based on this, the inner tank 10 of the rice receiving container 8 is rotated via the lever 17. Then, the passage ports 14 are made to face the closing portions 13 and are closed.

Then, the rice grains flowing into the rice receiving container 8 along with water from the discharge pipe 26 are captured in the rice receiving container 8 one after another, only the water is discharged through the overflow part 16, and after a while, all of the rice grains are trapped in the rice receiving container 8. is stored in At this time, the discharge pipe 26 and cover 32
Since it is transparent, it is possible to visually check whether or not rice grains are flowing into the discharge pipe 26, and it is possible to easily determine whether rice grain storage is completed by this visual inspection.

After all the rice has been stored in the rice receiving container 8, the valve of the faucet 28 is closed, and the discharge pipe 26 is rotated together with the cover 32 to evacuate it from above the rice receiving container 8. The rice receiving container 8 is taken out from inside the guide container 4. The water in the rice receiving container 8 flows out through the water passages 15, thereby draining the rice, so that the rice in the rice receiving container 8 can be directly transferred to a rice cooker and cooked.
