Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a grain washer for grains such as rice, wheat, and other grains.

``Prior Art'' Conventionally, this type of cleaning device was developed by forming a communication hole in the deepest part of the container developed by the present inventor, and placing the suction port of the circulation cleaning channel near the communication hole. Granules with a discharge port placed above the container, a fluid discharge pipe connected to the discharge port of the circulation cleaning channel via a switching valve, and an air jet device (air mixture jet) installed near the communication hole. Among cleaning devices, there is a granular cleaning device in which a circulating cleaning channel is spirally arranged around the outer periphery of a container. This is Special Publication No. 62-49102 ``Grain cleaning device.''

"Problem to be solved by the invention" When the amount of granules to be washed changes from a small amount (for example, 1 cup) to a medium amount (for example, 3 to 5 cups) to a large amount (for example, 1 sho), the amount of granules to be washed An appropriate amount of water is required. As the amount of granules increases, the amount of water also increases. When the granules are washed, the grinding fluid etc. must overflow and be discharged. In the case of one granule washer, the overflow point is one of the openings at the top of the container.
Since the amount of particles to be washed is small, medium, or large, it is not possible to wash the required amount of particles with the appropriate amount of water. Further, it is desirable that all the washing of the granules be done automatically.

"Means for Solving the Problem" In view of the above circumstances, the present invention provides a solenoid valve that opens and closes the water supply channel, and provides a cleaning water surface that adjusts the water level of the cleaning water depending on whether the amount of granules to be cleaned is small, medium, or large. A drainage hole is formed in each side wall of the container, a solenoid valve is provided in each drainage hole, and the granules are automatically cleaned.

"Operation" The water supply channel is opened and closed by a solenoid valve, and the drain hole is opened and closed by a solenoid valve so that the water level can be formed according to the amount of particles to be washed.

"Embodiment" A container 1 is open at the top, the bottom surface is formed into a funnel shape 2, and a communication hole 3 is bored in the deepest part. The suction port 5 of the circulation cleaning channel 4 provided spirally on the outer periphery of the container 1 is located near the lower part of the communication hole 3 of the container 1 and is in communication with the communication hole 3;
The outlet 6 of the circulation cleaning channel 4 is arranged above the container 1. By inserting a spiral baffle plate, a coiled body, or a rotating plate into the circulation cleaning channel 4, an even greater cleaning effect can be obtained. A circulation/discharge switch 7 is connected to the discharge port 6 to guide the washed granules out of the container 1. Further, as the mixing jet device, there is an air mixing jet device 9, and the air mixing jet device 9 (mixed air jet) is an in-pipe nozzle 1 that guides tap water.
0 and nozzle 1 in the pipe to mix air into the jet water.
It consists of an air introduction pipe 11 that opens near 0 and is provided on the side wall of the container 1. This aerated jet device 9 is attached to the circulating cleaning channel 4 so that the jetting direction faces the suction port 5 of the circulating cleaning channel 4. The diameter of the circulation cleaning channel 4 and the helical pitch are determined depending on the granule cleaning conditions.

Drain holes 21, 22, and 23 communicating with the inside of the container 1 are provided in the side wall of the container 1 at the surface of the washing water depending on whether the amount of granules to be washed is small, medium, or large.
The drainage holes 21, 22, and 23 communicate with a drainage passage 24 provided in the side wall of the container 1, and the lower end of the drainage passage 24 is a sewage discharge port 30. Drain hole 21 for small quantities, drain hole 22 for medium quantities, solenoid valve 2 to open and close the water supply channel
5, 26, and 27 are provided. In addition, the circulation cleaning channel 4
A drain port 31 is opened below the suction port 5, and a solenoid valve 32 for opening and closing the flow path of the drain port 31 is provided there. Further, when the flow path is clogged during cleaning near the drain port 31 at the lower part of the circulation cleaning flow path 4, the clogged particle discharge port 28 is opened, and a three-way pot 29 is provided thereto to take it out. The drain port 31 is an electromagnetic device that opens and closes the flow path of the drain port 31 to remove residual water remaining in the circulation cleaning flow path 4 and the container 1 when the granules have been discharged to the outside after cleaning of the particles has been completed. Valve 32 is actuated to discharge.

Next, the operation will be explained using an example of washing a medium amount of rice.

First, attach the tap water hose provided on the granule washer to the faucet, open the faucet, and insert the electric cord of the granule washer into the power socket. Pour a medium amount of rice into container 1. When the medium quantity operation push button 37 is pressed, the medium quantity operation lamp 38 lights up, and at the same time, the drain hole 22 is opened with the medium quantity solenoid valve 26, the tap water inlet is opened with the solenoid valve 27, and the tap water is air-filled. Flows into the mixing jet device 9, passes through the circulation cleaning flow path 4 through the discharge 6, and is discharged into the container 1.
The polishing fluid is circulated toward the drain hole 22 and discharged from the drain hole 22. When the rice washing is completed, the medium quantity operation lamp 38
goes out, and at the same time a buzzer sounds, the solenoid valve 27 closes the water supply port to stop the tap water, and the solenoid valve 26 closes the drain hole 22. Press push button 46 to stop the buzzer sounding. Next, switch the switch 7 to the outside, press the medium discharge push button 39, and the discharge lamp 43
lights up, and at the same time, the solenoid valve 27 opens the tap water inlet, the tap water flows into the aeration jet device 9, passes through the circulation cleaning flow path 4 through the discharge port 6, and the rice is removed from the outside by the switching pot 7. Discharge into a rice cooker (not shown). When the rice is completely discharged to the outside, the discharge lamp 43 turns off, the buzzer sounds, and the solenoid valve 2 closes.
7 closes the tap water inlet and the tap water stops. Press push button 46 to stop the buzzer sounding. Next, when the discharge port push button 44 is pressed, the drain lamp 45 lights up, and at the same time, the electromagnetic valve 32 opens and the remaining cleaning water in the container 1 and the circulation cleaning channel 4 is discharged from the drain port 31. When the remaining water is drained, the drain lamp 45 turns off.
At the same time, the buzzer sounds and the solenoid valve 32 closes the drain port 31.
Close. Press push button 46 to stop the buzzer sounding.
Note that the buzzers for the medium-volume operation lamp 38, the discharge lamp 43, and the drain lamp 45 are turned off by pressing the button 46 to turn off each buzzer.

If the amount of granules to be cleaned is small, press the small amount operation push button 34 to open the drain hole 21 using the small amount solenoid valve 25. In addition, the reference numeral 35 is a small quantity operation lamp, and the reference numeral 36 is a small quantity discharge push button. Reference numeral 40 is a large quantity operation push button, 41 is a large quantity operation lamp, and 42 is a large quantity discharge push button.

Note that a solenoid valve may be freely provided in the large-volume discharge hole 23. Furthermore, the number of discharge holes is not limited to three as in the above embodiment, and can be provided at any location in the vertical direction as required.
This control is performed by a microcomputer.

"Effects of the Invention" As described above, the present invention provides drainage holes that are formed in the side wall of the container at the surface of the washing water depending on whether the amount of granules to be washed is small, medium, or large. Since the valve is provided, even if the amount of particles to be washed differs, it can be washed with the optimum amount of water using one particle washer. Furthermore, even if the amount of granules to be cleaned differs, switching can be done automatically using a solenoid valve. Moreover, the present invention allows cleaning of granules to be automated.

If a pump is installed on the upstream side of the jet device and a solenoid valve is installed to open and close the water supply channel, it can be used in places with low water pressure such as high-rise residences, but this is not covered by the patent application filed on the same date as this patent application. Apply under 2.
