) Water is drained out of the strands. When a predetermined overflow time fff+ has elapsed, the solenoid valve (26) closes, the drain valve (24) opens, and the cleaning water that has been stored up to the overflow point in the tank is drained out of the system all at once.

With the above, the rice washing process is completed, and then the drain valve (24) is closed and the solenoid valve (48) is opened to start water supply in the water adjustment process. In this step, the circuit of the water level detection sensor (22) is turned on, and as the water level in the washing tank [5] rises, the float (20) in the first side pipe (19) rises, and the water level detection point (4) rises.
At step 7), the solenoid valve (48) is closed to stop the water supply.

Then, in response to the output signal of the sensor, the cam-type opening/closing mechanism (12) installed above the shaft (13) rotates, causing the conical valve (14) that seals the outlet (15) at the bottom of the rice washing tank to fall by a predetermined stroke to remove the raw material. The rice cooking water is allowed to flow down into the inner pot f3sl from the inlet (37) provided in the upper M (291).

The inlet (37) is always sealed by a shutter (41), temporarily opened by an electric fi (381) in response to an output signal from the sensor (22), and automatically closed after a predetermined period of time. It has been.Also #;
When the outflow of the conical valve (14) is completed, the conical valve (14) returns to its original position by the rotation of the cam opening/closing mechanism (12) and seals the outflow port (15).

Next, the water absorption time of the raw material is restricted by a timer which is activated upon detection of the completion of rice removal, and after a predetermined time has elapsed, the burner (not shown) of the rice cooker (44) is ignited by the output signal of the group timer and the rice cooking process begins. The combustion gas is supplied using a gas solenoid valve (
The solenoid valve is opened and closed by the output signal of the timer, and the inner pot (
35) is configured to be shut off by a thermostat (not shown) that detects the bottom temperature of the rice cooker.Completion of the rice cooking process is detected by the thermostat, and the burner is extinguished and another timer is activated to set the steaming time. After a predetermined steaming time has elapsed, the output signal of the timer notifies the completion of rice cooking, thereby completing the series of operating steps in the apparatus of the present invention.

In the present invention, the proposed upper lid mechanism equipped with a shutter (41) and an inlet port (37) that can be opened and closed is extremely effective in realizing the present invention, and the upper lid is heated during rice cooking. The bottom part of the rice washing tank placed above the rice washing tank and the conical valve are arranged with a space between them, so it is possible to eliminate all thermal effects on the raw materials waiting in the rice washing tank, and the area around the conical valve. It is easy to check the operation of the rice cooker, making it easy to clean.It also has the advantage of smooth opening/closing of the rice cooker and a highly airtight seal for the rice cooker.

Furthermore, in the rice cooker placed below, during each process such as water absorption of raw materials, cooking rice, steaming, etc., and after rice removal is completed, 1- Lift the lid, pull out the inner pot, and set the empty inner pot. During this period, the shutter (41) is electrically interlocked to prevent it from being opened, and a sensor (41) is installed to detect the opening of the shutter.
