Description

Grain washing device {GRAIN WASHER}

The present invention relates to a grain washing device, and more specifically, to a grain washing device for storing and washing grains such as rice.

In general, the outer surface of grains made of individual grains, such as rice and barley, is covered with foreign substances such as dust and dirt, or is coated with liquid substances harmful to the human body, such as pesticides.

Liquid substances such as pesticides sprayed during the cultivation process may still remain in the harvested grain and coat the outer surface of the grain, and foreign substances such as dust and dirt inevitably become attached to the grain during the cultivation or distribution process.

Most grains, such as rice or beans, are sold unwashed. Therefore, when preparing meals at home, restaurants, etc., the grains are washed in water at least once before being used.

For example, in order to cook rice at home or in a restaurant, the rice must first be washed. Washing rice is generally done by placing rice in a bowl-shaped washing container, pouring water into it, washing it, and then repeating the process of discarding the water.

According to this manual grain washing operation, not only does the washing operation take a long time, but there are also frequent cases where the grains are washed away during the process of pouring out the water with which the grains were washed.

In addition, a large amount of washing water is used in the washing process, and if excessive force is applied to wash the rice, problems such as falling off the rice germ or breaking the rice grains may occur. This is not only a problem in the rice washing process, but also occurs in the washing process of other grains such as beans and corn.

Additionally, in order to cook rice, an appropriate amount of rice must be washed and then the washed rice must be filled with an appropriate amount of water. However, if you are not used to cooking rice, it is difficult to measure the right amount of rice or fill the right amount of water to cook rice, and you end up having a lot of trouble cooking rice properly.

Prior Document 1 (Korea Registered Utility Model No. 20-0283285) discloses a water purifier that combines a rice container and a rice washer.

The device disclosed in Prior Document 1 includes a rice container 1, a rice washer 10, and a water purifier 14, as shown in FIG. 22. The rice in the rice container (1) enters the rice washer (3) through the open first opener (4). Then, tap water or water from the water purifier (14) enters the rice washer (3) through the open second switch (11) or fifth switch (15).

In this state, the electric motor 7 rotates to turn the rotating plate 8 inside the rice washer 3, and the rice is washed. When rice washing is finished, all the water drains out through the water outlet (9), and the water from the water purifier (14) enters the washer (3) and comes out through the rice outlet (6) together with the washed rice.

However, in the preceding document 1, it is not properly explained how rice is washed inside the rice washer 3. Prior Document 1 only discloses that the rotary plate 8 is rotated to wash the rice, but it also explains what shape the rotary plate 8 is provided and how the rice is washed by the rotation of the rotary plate 8. No specific explanation is disclosed.

Additionally, in Prior Literature 1, there is no explanation at all on how foreign substances washed out of rice are removed. Prior Document 1 simply states that once rice washing is finished, all water flows out through the water outlet (9), and the space between the rice washer (3) and the water outlet (9) is blocked with a screen (10), so even if the water flows out, It only discloses that rice cannot escape.

If the foreign matter washed out of the rice is significantly smaller than the rice, the foreign matter may be able to escape along with the water through the water outlet (9). However, if the size of the foreign matter is similar to or larger than the size of rice, the foreign matter cannot be separated from the rice because it is caught in the net (10) and cannot escape through the water outlet (9).

In other words, Prior Document 1 does not clearly present the specific structure and operation of the rice washer 3 and the rotating plate 8 for washing rice, and does not properly present a solution for separating rice and foreign substances.

Prior Document 2 (Korean Patent Publication No. 10-2004-0025414) discloses a refrigerated rice container equipped with an anhydrous rice washing machine.

The device disclosed in Prior Document 2 includes a rice storage chamber 111 and an anhydrous water washing machine 130, as shown in FIG. 23. The rice storage room 111 is provided inside the external case 111, and an anhydrous water washing machine 130 is provided in the lower part of the rice storage room 111. A rice container 113 is provided at the lower part of the anhydrous rice washing machine 130.

Inside the dry washing machine 130, a brush 132 is provided as a tool for washing rice. The anhydrous washing machine 130 washes rice using centrifugal force when rotating without water, and uses a brush 132 to remove foreign substances attached to the rice without water.

Even in prior literature 2, it is not clearly explained how rice is washed. Prior Document 2 only discloses washing rice using centrifugal force or using the brush 132. Whether the anhydrous washing machine 130 and the brush 132 rotate together, or the brush 132 It is not clearly disclosed whether rice is washed by rotation or by centrifugal force.

Also, in Prior Literature 2, it is not disclosed at all how foreign substances removed from rice are discharged separately from the rice.

In other words, Prior Literature 2 also does not clearly present the specific structure and operation of the anhydrous rice washing machine 130 for washing rice, and does not properly present a solution for separating rice and foreign substances.

In addition, Prior Document 2 simply removes foreign substances attached to rice without water, so it has a limitation in that it cannot properly remove liquid substances such as pesticides on rice.

Considering this, the opening and closing member 81 rotates downward and opens the discharge port 110a, so that the washed grain can be discharged by opening the discharge port 110a without much effort.

In addition, the opening and closing member 81, which is provided to rotate in the vertical direction as described above, can be in close contact with the cleaning container 110 while pressing the lower end of the cleaning container 110 in the upward direction. As the opening and closing member 81 can be brought into close contact with the cleaning container 110, airtightness between the opening and closing member 81 and the discharge port 110a can be effectively improved.

As a result, the grain washing device of this embodiment can effectively prevent grain or water leakage during the grain washing process.

In addition, the space required to place the cooking utensils (P) must necessarily be prepared on the lower side of the washing container 110. That is, since the washed grains are discharged to the lower side of the washing container 110 through the discharge port 110a, cooking utensils (P) to accommodate the discharged grains must be placed at the lower part of the washing container 110, and these cooking utensils The space required to place (P) (hereinafter referred to as “cooking utensil placement space”) must be prepared on the lower side of the washing container 110.

Most areas of the opening and closing member 81 that can be rotated in the vertical direction as described above are disposed in this cooking utensil arrangement space. In particular, the stopper 83 moves in the vertical direction within the cooking utensil placement space to open and close the outlet 110a, and there is no need to leave the cooking utensil placement space in this process.

That is, the stopper portion 83 can be moved within a range that does not deviate from the cooking utensil placement space, and in particular, may be provided so as not to deviate laterally to the outside of the cooking utensil placement space.

The size of the grain washing device of this embodiment equipped with such an opening and closing member 81 does not need to be increased laterally to form an opening and closing structure of the discharge port 110a.

That is, since the movement range of the opening and closing member 81 provided for opening and closing the discharge port 110a is limited to the space required for the cooking utensil (P) to be placed, there is no need to increase the size of the grain washing device due to the opening and closing member 81. will be.

As a result, the grain washing device of this embodiment has the advantage of being able to effectively prevent grain or water leakage during the grain washing process while maintaining a compact appearance.

[Structure related to water supply in the washing department]

Figure 12 is a side view showing the water supply structure of the grain washing device according to an embodiment of the present invention.

Referring to FIG. 12, the water supply units 51 and 52 may be connected to the cleaning member 120, and the water supplied through the water supply units 51 and 52 may be supplied to the cleaning container 110 through the cleaning member 120. Can be supplied internally.

For this purpose, an internal water conduit 120a may be formed in the cleaning member 120. The internal water conduit 120a is formed inside the cleaning member 120 and can connect the inside of the cleaning member 120 and the water supply unit 50. As an example, the internal water channel 120a is formed inside the rotating rod 121 and the washing rod 125, and can connect the inside of the rotating rod 121 and the washing rod 125 and the water supply units 51 and 52. .

The internal water conduit 120a may be connected to the second water supply pipe 52. The water supplied by the water supply unit 50, that is, the second water supply pipe 52, can move inside the rotating rod 121 and the washing rod 125 through the internal water passage 120a.

The cleaning member 120 may be provided with a water outlet 120b. The water outlet 120b may be provided on the washing rod 125. This water outlet 120b may form a passage in the cleaning rod 125 for the water in the internal water conduit 120a to be discharged to the outside of the cleaning rod 125. As an example, the water outlet 120b may be formed at the bottom of the cleaning rod 125.

The water supplied to the purification unit 53 through the first water supply pipe 51 may be filtered by the purification unit 53 and then discharged to the second water supply pipe 52. The water discharged to the second water supply pipe 52 moves inside the rotating rod 121 and the washing rod 125 through the internal water passage 120a, and then passes through the water outlet 120b to the bottom of the washing rod 125. can be discharged from

In this way, the water discharged from the bottom of the cleaning rod 125 gradually rises from the bottom of the second container 115 and fills the cleaning container 110.

Meanwhile, the cleaning rod 125 may include a first cleaning rod 126 and a second cleaning rod 127.

The first cleaning rod 126 may be connected to the lower end of the rotating rod 121, more specifically, the second rotating rod 123. This first cleaning rod 126 may extend from the rotating rod 121 in a direction between the downward and centrifugal directions of the rotating rod 121. For example, the first cleaning rod 126 may protrude downward from the bottom of the second rotating rod 123 in a centrifugal direction.

The second cleaning rod 127 may extend from the first cleaning rod 126 in a direction between the downward direction of the rotating rod 121 and the centripetal direction. For example, the first cleaning rod 126 and the second cleaning rod 127 protrude in the centrifugal direction from the lower end of the second rotating rod 123, and may protrude in a “〉” shape.

As an example, the first cleaning rod 126 may be disposed in the inner area of the first container 111. And the second cleaning rod 127 may be disposed in the inner area of the second container portion 115.

The second cleaning rod 127 extends obliquely from the first cleaning rod 126 in a direction between the downward and centripetal direction of the rotating rod 121, and is approximately parallel to the inclined surface formed by the bottom of the second container 115. can be extended in any direction.

The water outlet 120b may be disposed at the bottom of the second cleaning rod 127. Accordingly, the water supplied into the cleaning member 120 can be discharged through the water outlet 120b in the inner area of the second container 115, more specifically, at a location adjacent to the outlet 110a. .

In this way, when the cleaning rod 125 is buried in the grain contained inside the washing container 110, water is not supplied to the upper part of the grain-filled area, but to the grain-filled area, especially the outlet 110a. Water can be supplied to the lower area adjacent to the.

When water is supplied to the area filled with grains in this way, the hydraulic pressure of the water discharged from the cleaning rod 125 can have the effect of removing foreign substances attached to the grains from the grains.

In other words, the water discharged from the cleaning rod 125 can be added to the action of stirring the grain by rotating and lifting the cleaning member 120, thereby making it possible to remove foreign substances more effectively during the grain cleaning process.

[Structure related to drainage of washing part]

Referring to FIG. 7 , the washing unit 100 may include a first drain hole 110b and a second drain hole 110c. The first drain hole 110b and the second drain hole 110c may each form separate passages in the washing container 110.

As described above, the first drain port 110b may be disposed in the second container portion 115 and may be disposed above the discharge port 110a. And the second drain 110c may be located above the first drain 110b and may be placed in the first container 111.

The grain washing device of this embodiment may further include a first opening and closing unit 70 that controls the discharge of water through the first drain hole 110b. As an example, the first opening/closing unit 70 may include a first drain pipe 71 and a first valve 73.

The first drain pipe 71 may be provided in the form of a pipe connected to the first drain hole 110b. This first drain pipe 71 may extend outside the grain washing device. Water and foreign substances discharged from the inside of the washing container 110 through the first drain hole 110b may be discharged to the outside of the grain washing device through the first drain pipe 71.

The first valve 73 is provided to open and close the first drain pipe. When the first valve 73 opens the first drain pipe 71, foreign substances separated from grains inside the washing container 110 may be discharged into the first drain pipe 71 together with water.

Since the first drain (110b) is disposed in the lower area of the washing container (110), that is, the lower part of the area filled with grain and water, when the first drain (110b) and the first drain pipe (71) are always open, grain washing is possible. There is difficulty in securing the required amount of water inside the washing container 110.

Considering this, a first valve 73 is installed in the first drain pipe 71, and this first valve 73 controls drainage through the first drain port 110b and the first drain pipe 71. It can be used.

Additionally, the grain washing device of this embodiment may further include a second drain pipe 90. The second drain pipe 90 may be provided in the form of a pipe connected to the second drain hole 110c. This second drain pipe 90, like the first drain pipe 71, may extend outside the grain washing device. Water and foreign substances discharged from the inside of the washing container 110 through the second drain hole 110c may be discharged to the outside of the grain washing device through the second drain pipe 90.

Since the second drain 110c is located in the upper area of the washing container 110, that is, in an area higher than the area filled with grains and water, even if the second drain 110c and the second drain pipe 90 are always open, the second drain 110c Drainage performed through the drain hole 110c and the second drain pipe 90 does not significantly affect the amount of water filled inside the washing container 110.

Considering this, in this embodiment, the first valve 73 may be installed only in the first drain pipe 71, and the valve may not be separately installed in the second drain pipe 90.

In addition, the grain washing device of this embodiment may further include a third drain pipe 95. The third drain pipe 95 may be provided in the form of a pipe connected to the first drain pipe 71 and the second drain pipe 90.

The first drain pipe 71 and the second drain pipe 90 are connected to the third drain pipe 95, and may extend outside the grain washing device through the third drain pipe 95. Accordingly, water and foreign substances discharged through the first drain pipe 71 and the second drain pipe 90 can be discharged outside the grain washing device through the third drain pipe 95.

Meanwhile, the grain washing device of this embodiment may further include a first filter 116. The first filter 116 may be installed in the first drain 110b. This first filter 116 can filter between the washing container 110 and the first drain 110b so that only objects smaller than the grain size are discharged through the first drain 110b.

As an example, foreign matter smaller than the size of a grain may pass through the first filter 116. As a result, foreign substances smaller than the size of grains can be discharged through the first drain hole (110b) along with water.

The second drain 110c may form a passage through which objects larger than those that can be discharged through the first filter 116 can pass. To this end, the grain washing device of this embodiment may further include a second filter 112.

The second filter 112 may be installed in the second drain 110c. As an example, the second filter 112 may be configured to allow particles larger than those that the first filter 116 can pass through. This second filter 112 is a cleaning container 110 and a second filter so that foreign matter larger than the size that the first filter 116 can pass through can be discharged through the second drain 110c. Filtering is possible between drains 110c.

In this embodiment, the first valve 73 is illustrated as being installed between the first drain hole 110b and the third drain pipe 95. According to this, the first valve 73 is installed in the first drain pipe 71 and not in the third drain pipe 95.

This is the result of a design that takes into account that only the opening and closing control of the first drain pipe (71) is required and that the opening and closing control of the second drain pipe (90) is not required. If the first valve 73 is installed in the third drain pipe 95, the first drain pipe 71 and the second drain pipe 90 are closed simultaneously. If the second drain pipe 90 is also closed when the first drain pipe 71 is closed, the result is that water and foreign substances cannot be discharged through the second drain port 110c and the second drain pipe 90 at all times. It can happen.

As will be described later, unlike the first drain 110b and the first drain pipe 71, the second drain 110c and the second drain pipe 90 need to be always open. Taking this into consideration, in this embodiment, the first valve 73 is not installed in the second drain pipe 90 or the third drain pipe 95, but is installed in the first drain pipe 71 to connect the first drain pipe 110b and Only the first drain pipe (71) can be opened and closed.

According to this embodiment, foreign substances that are smaller than grains but have a greater specific gravity than water can be discharged through the first drain hole 110b. That is, foreign substances that are heavy enough to sink in water and have particles small enough to pass through the first filter 116 may be discharged to the outside of the washing container 110 through the first drain hole 110b.

Foreign substances with a specific gravity small enough to float on water may be discharged through the second drain 110c. That is, foreign substances whose particles are not small enough to pass through the first drain hole 110b but are light enough to float on water may be discharged to the outside of the washing container 110 through the second drain hole 110c.

Foreign substances can be discharged through the first drain hole 110b only when the first valve 73 opens the first drain pipe 71. In comparison, the discharge of foreign substances through the second drain 110c can occur at all times without limitation. That is, when the water inside the washing container 110 flows into the second drain hole 110c, foreign substances floating in the water may be discharged to the outside of the washing container 110 through the second drain hole 110c along with the overflowing water. there is.

[Parts arrangement structure of grain washing device]

Referring to Figures 1 to 4, most of the parts constituting the grain washing device can be accommodated in the space surrounded by the support part 10 and the case 20. For example, most areas of the grain storage unit 30 and the water supply unit 50, and the grain supply unit 40 can be accommodated in the space surrounded by the support unit 10 and the case 20 so as not to be exposed to the outside. .

As an example, the left-right length of the case 20 may be set shorter than the sum of the left-right length of the water purification part 53 and the left-right length of the cleaning container 110. According to this, the overall shape of the grain washing device can be set to a shape in which the length in the left and right directions is shorter than the length in the front and rear directions, that is, the left and right sides are slim.

This grain washing device appears to have a smooth and slim shape when viewed from the front, that is, in the direction from which the user is looking at the grain washing device.

Due to the shape of this grain washing device, the water purification unit 53 is disposed at the rear of the washing container 110. Due to the shape of the grain washing device where the left and right sides are slim, it is difficult for the water purification unit 53 to be placed on the side of the washing container 110. In addition, the washing container 110 is preferably disposed in a position biased forward in the grain washing device in order to discharge the grains washed in the washing unit 100 to a location adjacent to the user. Taking this into consideration, the water purification unit 53 may be disposed at the rear of the washing container 110.

Additionally, the grain storage unit 30 is disposed on the upper side of the washing container 110 and the purification unit 53. As the size of the grain storage unit 30 increases, the amount of grain that the grain washing device can store can increase. As the amount of grain that the grain washing device can store increases, the number of times grain is input into the grain washing device can be reduced, and user convenience can be improved.

This grain storage unit 30 is preferably placed at the top of the grain washing device. Due to the shape of the grain washing device where the left and right sides are slim, it is difficult to place the grain storage unit 30 on the side of the washing container 110 or the water purification unit 53.

Additionally, if the grain storage unit 30 is disposed at the bottom of the grain washing device, a problem arises in that an excessively long and complicated transport device must be added to supply the grain stored in the grain storage section 30 to the washing unit 100.

In addition, if the grain storage unit 30 is placed behind the purification unit 53, the distance between the grain storage unit 30 and the user becomes large, which not only makes it difficult for the user to put grain into the grain storage unit 30. , Due to the size of the grain storage unit 30, a problem occurs in which the front-to-back length of the grain washing device becomes excessively long.

In addition, if the grain storage unit 30 is placed behind the water purification unit 53, difficulties may arise in arranging the grain storage unit 30 and the water supply pipe and drain pipe due to various water supply pipes and drain pipes extending to the rear of the grain washing device. You can.

Considering this, in this embodiment, the grain storage unit 30 is disposed at the top of the grain washing device. Accordingly, the grain storage unit 30 can secure a grain storage space having an anteroposterior length equal to the sum of the anteroposterior length of the purification unit 53 and the anteroposterior length of the washing container 110.

Additionally, if the grain storage unit 30 is placed at the top of the grain washing device, grain can be input through the front top of the grain washing device, which is easily accessible to the user. That is, by placing the grain storage unit 30 at the top of the grain washing device, grain input into the grain storage unit 30 can be performed more easily.

According to this embodiment, the grain discharge port 32 is disposed in a position biased toward the rear in the grain storage unit 30, and the washing container 110 is disposed in a position biased forward in the grain washing device.

As described above, the grain discharge port 32 is preferably disposed at a position biased toward the rear of the grain storage unit 30 in order to effectively induce first-in-first-out of grain. In addition, the washing container 110 is preferably disposed in a position biased forward in the grain washing device in order to discharge the grains washed in the washing unit 100 to a location adjacent to the user.

In this way, a grain supply unit 40 may be provided to transport grain from the grain discharge port 32 disposed at a position spaced apart in the front and rear direction to the washing container 110. This grain supply unit 40 can transport the grain discharged from the grain discharge port 32 to the front side and supply it into the washing container 110.

That is, the washing container 110 is placed at the front of the grain washing device, the water purification unit 53 is located at the rear of the washing container 110, and the grain storage unit 30 is located at the top of the grain washing device. The fact that the grain supply unit 40, which transports the grain discharged from the grain storage unit 30 to the front, is disposed between the grain storage unit 30 and the washing container 110 ensures that the grain washing device has a smooth appearance. This is the result of a design that allows the input of grain and the collection of washed grain to be carried out conveniently and effectively while maintaining a slim shape.

[Washing operation of grain washing device]

Figures 13 to 19 are side views showing the grain washing operation of the grain washing device according to an embodiment of the present invention, and Figure 20 is a flow chart showing the grain washing operation of the grain washing device according to an embodiment of the present invention.

Hereinafter, the grain washing operation of the grain washing device according to this embodiment will be described with reference to FIGS. 12 to 20.

Referring to Figures 12 and 20, the grain washing device of this embodiment can first supply grain to the washing container 110 for grain washing (grain supply step; S10). Grain supply may be carried out in such a way that the grain supply unit 40 transfers the grain discharged from the grain storage unit 30 to the washing container 110 and then inputs it into the washing container 110.

As an example, in the grain supply step, grain may be supplied into the washing container 110 so that the grain is filled inside the washing container 110 at a height lower than the second drain hole 110c. Preferably, the inside of the washing container 110 may be filled with grains to the height between the first drain hole (110b) and the second drain hole (110c).

At the same time, water can be supplied to the washing container 110 as much as the first set amount (first water supply step; S20). As an example, the first water supply step (S20) may proceed after the grain supply step (S10) is completed. As another example, the grain supply step (S10) may proceed after the first water supply step (20) is completed. As another example, the grain supply stage (S10) and the first water supply stage (S20) may be carried out together or with a slight time difference. In this embodiment, a case in which the first water supply step (S20) is performed after the grain supply step (S10) is completed is exemplified.

In this embodiment, the first set water quantity is defined as a quantity that maintains the water level inside the washing container 110 lower than the second drain hole 110c. That is, in the first water supply step (S10), water may be supplied into the cleaning container 110 to the extent that the water level inside the cleaning container 110 is maintained lower than the second drain hole 110c.

Preferably, in the first water supply step (S10), water is supplied inside the washing container 110 so that the water level inside the washing container 110 is maintained between the first drain hole (110b) and the second drain hole (110c). You can.

More preferably, in the first water supply step (S10), water may be supplied so that the water level inside the washing container 110 is maintained higher than the grain filled inside the washing container 110 and lower than the second drain hole 110c. .

After grains and a first set amount of water are supplied into the washing container 110, the first washing step (S30) may be performed, as shown in FIGS. 13 and 20. In the first washing step (S30), the grain and water contained in the washing container 110 may be agitated using the washing member 120.

The cleaning member 120 performs a rotating operation and a lifting operation together and can evenly stir grains in various directions. This cleaning member 120 not only expands the range that can be stirred in the vertical direction to evenly stir the entire grain contained in the washing container 110, but also performs rotating and lifting operations together to move in various directions. Grains can be stirred.

As a result, the washing member 120 can effectively wash the grains contained in the washing container 110 evenly and more cleanly.

While the first washing step (S30) as described above is in progress, as shown in FIGS. 14 and 20, a second water supply step (S35) in which more water is supplied to the washing container 110 may be performed.

In the second water supply step (S35), water may be supplied into the cleaning container 110 so that at least some of the water inside the cleaning container 110 can be discharged to the outside of the cleaning container through the second drain hole 110c. . In this secondary water supply step (S35), water may be supplied into the cleaning container 110 so that the water level inside the cleaning container 110 can be raised higher than the second drain hole 110c.

The second water supply step (S35) may be performed intermittently multiple times while the first washing step (S30) is in progress. That is, while grain washing is in progress, additional water may be supplied so that water overflows through the second drain 110c intermittently.

While the first washing step (S30) is in progress, foreign substances attached to the grain may be separated from the grain by the washing member 120 that stirs the grain. Among these foreign substances, those lighter than water do not sink into the water but float on the water.

In this state, with foreign substances floating on the water, the second water supply step (S35) proceeds and additional water is supplied, and accordingly, when water overflows through the second drain (110c), the water floating on the water Foreign substances may be discharged to the outside of the washing container 110 through the second drain hole 110c along with water.

In this way, water and foreign substances discharged through the second drain 110c can be discharged outside the grain washing device through the second drain pipe 90 and the third drain pipe 95.

As described above, the second water supply step (S35) may be performed while the first washing step (S30) is in progress. That is, additional water can be supplied while the cleaning member 120 rotates and moves up and down.

By rotating and lifting the cleaning member 120, the overflow of water through the second drain pipe 90 can be further promoted. That is, not only the additional supply of water, but also the rotation and lifting motion of the cleaning member 120 can induce water to overflow through the second drain pipe 90 and discharge of foreign substances through it.

Meanwhile, water supply as described above may be provided through the water outlet (120b) at the bottom of the cleaning member (120). When grain is supplied into the washing container 110, most areas of the cleaning member 120 remain buried in the grain, and accordingly, the water outlet 120b is also in a state buried in the grain.

As a result, water is discharged through the cleaning member 120 from the lower part of the grain rather than the upper part of the surface layer of the grain. That is, water may be supplied in the form of water being discharged from the cleaning member 120 in the area covered with grains, especially in the lower area.

In this way, the flow of water discharged from the lower area of the grain causes foreign substances separated from the grain to float to the upper part of the grain surface layer during the grain washing process, while preventing foreign substances floating on the upper part of the grain surface layer from entering the lower part of the grain surface layer again. It may have a suppressive effect.

Additionally, the lifting motion of the cleaning member 120 during this process may promote foreign substances separated from the grain during the grain washing process to float to the upper part of the surface layer of the grain.

After the first washing step (S30) and the second water supply step (S35) as described above are performed for a set time or number of times, the draining step (S40) may be performed, as shown in FIGS. 15 and 20. In the draining step (S40), the first drain (110b) is opened, and thus foreign substances discharged from grains in the first washing step (S30) can be discharged through the first drain (110b) along with water.

The first drain 110b may be opened as the first valve 73 opens the first drain pipe 71. Water and foreign substances discharged through the first drain 110b may be discharged to the outside of the grain washing device through the first drain pipe 71 and the third drain pipe 95.

In the draining step (S40), foreign substances that are smaller than grains but have a greater specific gravity than water, that is, foreign substances that are heavy enough to sink in water and whose particles are small enough to pass through the first filter 116, are transferred to the first drain ( It can be discharged to the outside of the grain washing device through 110b).

That is, in the drainage step (S40), foreign substances that have settled to the bottom of the grain may be discharged to the outside of the grain washing device along with water. Preferably, as much water as possible can be discharged outside the grain washing device in the draining step (S40).

The more water remaining without being drained in the draining step (S40), the more likely it is that foreign substances will remain inside the washing container 110 along with the water. Considering this, it is desirable that as much water as possible is discharged along with foreign substances in the draining step (S40).

That is, in the drainage step (S40) of this embodiment, drainage can be performed considering only the efficiency of discharging foreign substances without considering the amount of water needed for cooking.

The first water supply step (S20) to the drainage step (S40) are processes directly related to grain washing. This process can be repeated multiple times as needed. That is, depending on the number of grain washings required, the first water supply step (S20) to the drainage step (S40) may be repeated several times.

After grain washing is completed, the first discharge step (S50) may proceed, as shown in FIGS. 16 and 20. In the first discharge step (S50), the discharge port 110a is opened, and thus the grain and water contained in the washing container 110 can be discharged. In this way, the washed grains and water discharged through the outlet 110a can be supplied to the cooking utensil P discharged from the lower part of the outlet 110a.

In the first discharge step (S50), it is difficult for all grains inside the washing container 110 to be supplied to the cooking utensil (P). That is, even if grains are discharged in the first discharge step (S50), a significant amount of grains may be attached to the washing container 110 and the washing member 120.

In addition, in the drainage step (S40), since drainage was performed considering only the efficiency of discharging foreign substances without considering the amount of water needed for cooking, the cooking utensil (P) supplied with the washed grains lacks the water needed for cooking.

Considering this, a secondary washing step (S60) may be added in this embodiment. The second washing step (S60) may be performed in the form of washing the inside of the washing container 110 after the first discharging step (S50) is completed.

In the secondary washing step (S60), as shown in FIGS. 17 and 21, the outlet closing step (S61) may be performed first. After the first discharge step (S40) is completed, the discharge port (110a) may be closed in the outlet closing step (S61).

Then, the third water supply step (S62) of supplying water to the inside of the washing container 110 may proceed. At the same time, as shown in FIGS. 18 and 21, the cleaning member operation step (S63) may proceed. In the cleaning member operation step (S63), the water filled inside the cleaning container 110 is stirred using the cleaning member 120.

At this time, the cleaning member 120 may stir the water by simultaneously performing a rotating operation and a lifting operation, as in the first washing step (S30). However, unlike the first washing step (S30), the washing member operation step (S63) does not involve washing the grains, but rather cleans the grains attached to the cleaning member (120) or the washing container (110) to the cleaning member (120) or the washing container (110). An operation may be performed to generate a water flow for removal from the cleaning container 110.

The 3rd water supply step (S62) and the cleaning member operation step (S63) may be performed simultaneously, or the cleaning member operation step (S63) may be performed after the 3rd water supply step (S62) is completed.

Among the foreign substances separated from the grains during the first washing step (S30), foreign substances that are lighter than water and float on the water (hereinafter referred to as “floating foreign substances”) are washed into the washing container (110) through the second drain (110c). ) can be discharged to the outside.

The second drain 110c is disposed at a higher position than the surface layer of grains filled inside the washing container 110. Accordingly, floating foreign substances can be discharged to the outside of the washing container 110 through the second drain hole 110c at a position higher than the grain layer without having to pass through the grain layer filled inside the washing container 110.

If the second drain 110c is not provided in the washing unit 100 and only the first drain 110b is provided, floating foreign matter is discharged to the outside of the washing container 110 only when drainage is made through the first drain 110b. may be discharged.

However, for this to happen, floating foreign matter must pass through the grain layer. This is because the first drain hole 110b is disposed at a lower position than the surface layer of the grains filled inside the washing container 110.

However, because it is not easy for floating foreign matter to properly pass through the grain layer, these floating foreign materials cannot pass through the grain layer and be discharged to the first drain hole (110b) when draining through the first drain hole (110b), and remain on the surface layer of the grain or return to the drain. It is easy to get mixed up among grains.

Considering this, in this embodiment, a second drain hole 110c is additionally provided on the upper side of the first drain hole 110b. Through this second drain hole 110c, suspended foreign substances separated from grains can be discharged to the outside of the washing container 110 very effectively.

In addition, in the process of discharging floating foreign substances as described above, water is discharged through the cleaning member 120 from the lower part of the grain layer, and the lifting operation of the cleaning member 120 is also performed along with the rotation motion of the cleaning member 120.

Accordingly, the floating of foreign substances separated from the grain during the grain washing process is induced, and the entry of floating foreign substances into the grain can be suppressed.

In addition, foreign substances heavy enough to sink in water may be discharged out of the washing container 110 through the first drain 110b instead of the second drain 110c.

That is, through the first drain 110b and the second drain 110c arranged in the vertical direction, both light foreign matter floating in the water and heavy foreign matter settling in the water are effectively separated from the grain during the grain washing process and then separated from the grain. may be discharged.

As a result, the grain washing device of this embodiment can effectively remove both light foreign substances floating in water and heavy foreign substances that settle in water from grains, and provide the effect of providing cleanly washed grains in a state ready for cooking.

In addition, the grain washing device of this embodiment first discharges the washed grains, and then discharges the remaining grains attached to the washing container 110 and the washing member 120 through a secondary washing step, washing the washing container 110. And the operation of removing grains attached to the cleaning member 120, and the operation of supplying water necessary for cooking can be performed together.

This grain washing device not only suppresses the generation of residual grains after washing and effectively provides washed grains required for cooking, but also maintains the cleanliness of the washing unit 100 easily and conveniently, and improves the convenience of cooking work and It can also provide effects that can improve efficiency.
