Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an automatic rice cooker for cooking cereals, for example, rice.

[0002]

2. Description of the Related Art It is a common practice to reciprocate a shutter for opening and closing a receiving port for washed rice and water for cooking rice by a shutter opening / closing arm via a driving means such as an electric motor.

[0003]

However, when rice is cooked, spills from the inner pot are transmitted through the shutter opening / closing arm.
For example, it may flow to a sensor or the like and cause erroneous sensing.

[0004]

SUMMARY OF THE INVENTION The present invention provides a grain washing apparatus which solves such a problem.
The following technical measures were taken. That is, it comprises a grain storage unit 1, a washing device 2, and a rice cooker 3. Moving shutter opening / closing arm
And an automatic rice cooker comprising the shutter opening / closing arm 8 and the water absorbing body 9.

[0005]

According to the present invention, the rice and the water for washing sent from the grain storage unit 1 are stored and washed in the washing device 2, and then the washed rice and the water for rice cooking are put on the lid 5 of the rice cooking unit 3. It is received in the inner pot 4 from the receiving port 6. Then, the shutter opening / closing arm 8 is operated to move the shutter 7 to close the receiving port 6, and the rice cooking operation is performed by the heating means. At the time of cooking rice, the water blown from the kettle and flowed to the shutter opening / closing arm 8 is absorbed by the water absorbing body 9.

[0006]

According to the present invention, even if the blow-out from the pot flows into the shutter opening / closing arm 8, the flow can be stopped by the water absorbing member 9 on the way. It can be performed efficiently.

[0007]

Embodiments of the present invention will be specifically described below with reference to the drawings. First, the structure of the automatic rice cooker 10 will be described. In the automatic rice cooker 10, a cereal storage unit 1, a washing device 2, and a rice cooker 3 are sequentially arranged on a frame 11 from above, and the rice cooker 3 is provided so as to be movable in the front-rear direction. ing.

The grain storage unit 1 has a lower end portion detachably provided on a top plate 12 having a communication port, and a hollow hopper 13 having upper and lower ends open and a lower end formed to be thin.
The interior is decorated. In addition, a communication passage 15 that communicates with a communication port with a washing tank 14 to be described later has a cylindrical rice feeder 17 that has a receiving hole 16 in a part of the outer surface and is rotatably provided.
It has.

The washing device 2 has a hollow tank 14 having a lower portion formed to be thin and having a circular shape in a plan view, which is detachably attached to the lower surface of the top plate 12, and a stirring device provided at the center of the tank 14. And a drop valve 21 for opening and closing a rice discharge port 20 of a jacket 19 detachably attached to a lower end of the tank 14. The stirring device 18 includes a hollow stirring shaft 24 rotatably provided with a motor 22 as a driving source and having a shaft center 24a in a vertical direction, and a stirring body 25 attached to the stirring shaft 24. I have.

Reference numeral 26 denotes an operation panel which is detachably provided on the front wall of the grain storage unit 1, and displays a switch unit A in which various switches for setting rice cooking conditions are arranged, the number of pots, the state of counter-sucking operation and the like. A display section B having a display tool is provided.
The drop valve 13 is detachably provided at the lower end of a valve shaft 23 which moves up and down the inside of the stirring shaft 15 using a motor 21 as a drive source.

The jacket 19 has a drain box 27 on the side wall of the middle part.
Drain opening / closing valve 3 that opens and closes via an operating mechanism 31 operated by a solenoid 29
0 is provided. The drain opening / closing valve 30 is usually provided with a spring 3
2 to close the drain 28. Reference numeral 33 denotes a drain pipe having one end connected to the drain box 28 and the other end looking into the drain channel, and a suction fan 34 is connected to a middle part of the drain pipe 33.

This makes it possible to forcibly discharge foreign substances such as dust remaining in the drain box 28 or the drain pipe 33, so that clogging of the drain pipe 33 can be eliminated and cleaning can be performed efficiently. . Reference numeral 35 denotes a water supply pipe for supplying water to the tank 1 from above. The water supply pipe drain port 36 is viewed from the top plate 12 into the tank, and a check valve 37 and a solenoid valve 38 are arranged in the middle part in this order from the drain side. It is provided so that it can communicate with the water supply source. The check valve 37 is connected to the
It is located higher than the bar flow port 39.

As a means for preventing rats and cockroaches from entering, an opening / closing valve 41 is provided at a position facing the communication port 40 between the drain pipe 33 and the drain box 27.
During the cleaning operation, the communication port 40 is opened and closed by moving in the axial direction. Therefore, when the washing operation is completed, if the communication port 40 is closed by the on-off valve 41, even if a mouse or the like enters the drain pipe 33, the on-off valve 41 can be prevented from entering the drain box, which is sanitary. .

The rice cooker 3 has a shutter 7 for opening and closing a receiving port 6 provided at a central portion of a lid 5 for covering the inner pot 4, and a shutter for reciprocating the shutter 7 in a horizontal direction along a guide rail G. An opening / closing arm 8 is provided. The shutter opening / closing arm 8 is provided with a water absorbing body 9 (for example, a sponge) having a water absorbing function on a support frame S provided with a large number of holes on both left and right sides.

Although not shown, the operation of each device is managed by a microcomputer. Next, the operation will be described. First, the operator operates the various switches of the switch section A of the operation panel 26 and the rice cooking amount switch to set the rice cooking conditions. When the operation start switch is turned on, the motor is started by the micro computer. The rice feeder 17 is driven to supply a fixed amount of rice stored in the grain rice storage unit 1.

Next, an "open" signal is output to the solenoid valve 38, and the motor 22 is started, so that the water sent from the water supply source passes through the water supply pipe 35 and the check valve 37 and enters the tank. And the stirring shaft 24 rotates to stir and wash the water and rice. The sewage generated at this time is stored in the tank 14
Through the drainage opening 27 and the drainage opening 28 by pushing the drainage opening / closing valve 30 closing the drainage 28 by the pressing force of the spring 32. It is discharged outside the machine from the pipe discharge port 36. When the washing operation is completed, the electromagnetic valve 38 is closed and the driving of the motor 22 is stopped, so that the water supply and the stirring are stopped.

When the sewage in the tank is drained (controlled by time), the solenoid valve 38 is opened, and the drain valve 30 is moved by the excited solenoid 29 to close the drain port 28. The incoming water is supplied from the water supply pipe 35 into the tank through the check valve 37, and the water is stored in the tank 14. Then, when a predetermined time comes, the electromagnetic valve 38 is closed,
Finish the water supply work and add water.

Next, when the motor 22 is driven to lower the drop valve 21 provided on the valve shaft 23 to open the rice discharging port 20,
The rice and water in the tank 14 fall and are stored in the inner pot 4 through the receiving port 6 of the lid 5 of the rice cooker 3 below. Then, the shutter opening / closing arm 8 is operated to move the shutter 7 in the horizontal direction, close the receiving port 6, turn on the ignition switch, and start the rice cooking operation. As the rice cooks, the water of the cooked rice may be heated and blown out from the inner pot 4, and the blowout may flow out to the shutter opening / closing arm 8. However, since the blow-off is absorbed by the water-absorbing body 9 provided in the shutter opening / closing arm 8, it can be prevented from adhering to electrical components such as sensors, and accurate rice cooking can be performed.
