The present invention will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 4 and FIG. 45, the rice storage and conveying apparatus 136, 4, the rice measuring apparatus 8, the rice conveying apparatus 170, the purified water supply apparatus 87, , Rice washing device 134, waste water discharge device 88, rice cooker lid automatic opening and closing device 140, before and after the rice cooker 135, and the pressure knob of the rice cooker automatic locking device 171 It is.

The rice feed and open / close device 4 is composed of a rice feed pipe portion 37, a rice feed opening / closing valve 46, and a screw portion 36, as shown in Figs. 5 and 8a. .

The rice supply opening and closing valve 46, as shown in Figure 7, the opening of the same square as the opening of the supply pipe 5 is formed on one side of the body (2) supply pipe (5) A rubber-based baring roller 3 is coupled between the two upper and lower collars 47 formed thereon, the shaft of the geared motor 26 circumscribed to the baring roller 3. The fixed roller is covered with the protective cap 23.

Therefore, when the rice in the rice storage container 16 is transferred through the supply pipe 5 for cooking purposes, the rice supply opening and closing valve 46 is opened and closed by the rotation of the geared motor 26 and the roller 20. As the valve body 2 is rotated 180 °, the opening of the on-off valve body 2 and the opening of the supply pipe 5 coincide with each other, so that the rice in the rice reservoir 16 rises by the rotation of the screw part 36. When the rice conveying device is operated for the purpose of disassembly and assembly, the on-off valve body 2 is rotated 180 ° again by the rotation of the geared motor 26 and the roller 20 to rotate the on-off valve body. (2) block the opening of the supply pipe (5), the supply pipe (5) as the screw portion 36 rotates in a state that the rice in the rice reservoir (16) is not carried into the supply pipe (5) Remaining rice is conveyed upward to the meter frame 11, and then the return opening valve and the return pipe From rice it is conveyed to the reservoir 16.

The screw portion 36 is composed of a screw 24 and its shaft 21 and a rice pinch pipe 22, as shown in FIGS. 8 and 10, wherein the rice pinch prevention pipe ( 22 is fixed to the screw blade edge to prevent rice pinching between the screw 24 and the three stage feed pipe 5 when the rice is conveyed up into the screw portion 36, which screw portion 36 The power transmission means of the first bevel gear 27, the first bevel gear 28 and the first sprocket connected to the shaft by the operation of the geared motor 26 of the stationary area fixed to the bottom of the rice barrel frame (17) The first sprocket 19a provided on the shaft 21 of the screw portion 36 and the first sprocket 19b connected to the shaft 39 are fixed to the shaft 39 and rotated, respectively.
