The rice cooker 11 has an outer pot, an inner pot, and a lid placed on a rice cooker 42 provided to be movable in the front-rear direction with respect to the leg frame 7 of the main frame 8 in a front view of the rice washing rice cooker 4. And the like, and a rice cooker 43 made of the same. Next, the operation will be described.

First, the rice cooker 42 is pulled out to the front side, the rice cooker 43 with the lid removed is placed on the rice cooker 42, and the rice cooker 42 is pushed rearward to be set at a predetermined position below the tank 1. Subsequently, a desired rice amount is selected by operating a switch on the operation panel 14, and then the main switch is turned “ON” and the work start switch is turned “ON”. Then, the fixed supply roll rotates to supply a predetermined amount of rice to the tank 1 every rotation. Then, when the number of rotations corresponding to the set rice amount is reached, the fixed-amount supply roll stops rotating. In addition, driving of each device (each device of the main body, solenoid valve, etc.)
The stop is not shown, but is controlled by a microcomputer while keeping the timing.

Next, when the motor 17 is driven, the motor 17 is driven.
The rotating power is transmitted to the rotating shaft 16 via the worm wheel 19 and the worm wheel 20, so that the rotating shaft 16 rotates together with the rotating shaft 16 to rotate the stirring blade 21. Further, water is supplied to the tank 1 by a water supply means. Therefore, rice has stirring blades 2
1. Adhering foreign substances such as debris and dust which are agitated by a water flow or the like are separated. Then, the foreign matter enters the jacket 24 through the hole 28 of the filter 25 together with the waste water and is discharged to a predetermined place.

When the above-mentioned rice washing operation reaches a predetermined time, the motor 17 is stopped, so that the rotating shaft 16 is also stopped and the rice washing operation is completed. When the waste water in the tank 1 is discharged, the drain hole of the jacket 24 is closed. When a predetermined amount of water is supplied to the tank 1 by the water supply means, the water supply operation is stopped. If the hole 28 of the filter 25 is a round hole at the time of discharging the wastewater, the broken rice is hardly clogged in the hole, and the drainage capacity may be reduced, so that the frequency of cleaning the filter 25 increases. In addition, in the means in which the water level is controlled by the drainage time, the precision of the water level is low. Then, it is conceivable to make the hole 28 vertically long, but with this means, broken rice is piled up.
However, in the embodiment, since the hole 28 is formed as a long hole in the lateral direction, even if broken rice enters the hole 28, it is easily removed by the subsequent rice or water. Therefore, the filter 25 is not easily clogged, so that the cleaning work is reduced, the discharge capacity is stabilized, and the variation in water level is small.

Next, the motor 31 is driven to drive the cam mechanism 3.
Activate 2 In this connection, the valve shaft 2 moves downward to release the closing by the valve 3, so that the water and rice stored in the tank 1 fall through the tank 1, the filter 25, etc., and fall into the rice cooker 43. Is collected in the inner pot. In the embodiment, the valve 3 can be used as a packing function by forming the valve 3 from an elastic body such as rubber (see FIG. 11). Therefore, rice is 3
When the valve 3 is closed in a state where it adheres to the valve 3, the valve 3 and the packing 26 are closed.
Are deformed and adhere to each other, so that no water leakage occurs.

When the rice discharging operation is completed, the motor 31
Is driven again to actuate the cam mechanism 32. In this connection, the valve shaft 2 is moved to a predetermined upper position, and the valve 3 is brought into contact with the packing 26 to close the passage of the filter 25. During this upward movement, if a stone enters between the valve 3 and the packing or if the valve 3 is mounted at or above the mounting position (upward), the movement of the valve 3 is regulated before the valve shaft 2 reaches the predetermined position. Is done. For this reason, a mechanical lock may occur, and the motor serving as a driving source may break down. In the embodiment, the valve shaft 2 and the valve 3 move integrally as described above with a load (load) within a predetermined range, but when the load (load) exceeds a predetermined range, the valve shaft 2, the spring receiving plate 38, the butterfly The nut 39 moves upward while compressing the spring 37. Therefore, since the mechanical lock does not occur, there is no failure of the motor 31 which is the driving source. Further, the position of the valve 3 can be easily adjusted by the tightening position of the butterfly nut 39.

Next, the rice cooker 42 is moved to the front side, the inner pot is covered, and then pushed backward to set the rice cooker at the original position. Then, the ignition switch (not shown) is turned “ON” to start the rice cooking operation (gas, electric heat, etc. as a thermal power source). Thereafter, high-temperature steam emerges from the rice cooker 43 and floats. When the steam hits the valve, the temperature of the valve becomes high, so that the rice on the valve tends to be half-boiled due to the heat, and the rice adheres to the filter when the rice is drained, and the remaining rice may be generated.
In this embodiment, a heat shield 40 having a large-diameter surface 41 provided below the valve 3 prevents the floating of steam, and since there is an air layer between the valve 3 and the heat shield 40, heat is released from the valve. It is hard to tell to 3.
Therefore, the remaining rice at the time of discharging rice is reduced and the unevenness of water absorption of the rice is reduced, so that it is possible to cook rice with good quality.

The packing 26 has grooves A, B, C,
Since the packing 26 is provided, the packing 26 is deformed into these grooves when the packing 26 is pressed (compressed) by the fixing plate 27. Accordingly, since no gap is formed between the valve 3 and the packing 26, the occurrence of water leakage can be prevented. Also, the assembly of the packing 26 is simplified.

It is possible to loosen the butterfly nut 39 to remove the valve shaft 2, remove the heat shield 40, the spring receiver 38, and the spring 37 from the valve shaft 2 in that order, and then remove the valve 3.
