  Next, when the rice washing operation for a predetermined time is completed, water addition / reduction is executed, the dropping valve 22 is moved downward by driving the dropping motor 52, the bottom of the rice washing tank 11 is opened, the shutter 55 is opened, and the rice charging hole 57 is opened. By doing so, rice and water are dropped and supplied to the rice cooker 4. Next, the heating means of the rice cooker 4 starts heating, rice cooking is started, and when the cooking time for a predetermined time is finished, the heating is stopped and the rice cooking work is finished.

Next, the heat shielding structure of the lower part of the rice washing tank 11 is demonstrated based on FIG.
The rice washing tank 11 is composed of an upper cylindrical tank 11a and a lower conical hopper portion conical tank 11b, and the heat shield 31 extends from the entire outer periphery of the lower outer periphery of the conical tank 11b to the outer peripheral side. It is attached. The inner peripheral side portion of the heat shield plate 31 is configured to be substantially horizontal, and the outer peripheral side portion is configured to be gradually inclined upward toward the outer side. It is comprised substantially the same as the diameter of.

According to the said structure, it can prevent that the lower part of the rice-washing tank 11 is exposed to the vapor | steam which stands | starts up from the rice cooker 4, and can prevent that rice adheres to the lower internal peripheral surface of the rice-washing tank 11. FIG.
In addition, if the diameter of the heat shield plate 31 is at least larger than the diameter of the middle portion in the vertical direction of the conical tank 11b, a sufficient heat shield effect can be obtained. If comprised in this way, the steam which stands | starts up from the rice cooker 4 can be guided in the direction away from the lower part of the conical tank 11b of the rice washing tank 11, making the magnitude | size of the heat shield 31 into the magnitude | size which does not disturb an operator. A heat shielding effect can be exhibited.

  A jacket 15 is attached to the lower end of the rice washing tank 11 so as to protrude all around, and the jacket 15 is attached to the end of the lower water supply pipe 16 and the end of the lower air supply pipe 18 as shown in FIGS. The side is attached. A heat shield plate 31 is detachably bolted to the upper surface of the jacket 15. By the said structure, it can prevent exposing the lower part of the conical tank 11b of the rice washing tank 11 to the vapor | steam which rises from the rice cooker 4, making the attachment operation | work of the heat shield 31 easy.

Next, the vertical adjustment structure of the drop valve 22 will be described with reference to FIG.
A diffusion blade 50 that rotates around the dropping shaft 21 is provided in the rice washing tank 11, and a dropping valve 22 is attached to the lower end of the dropping shaft 21. A screw portion 21 a is formed in a portion protruding upward from the upper end portion of the rice washing tank 11 above the dropping shaft 21, and a handle 23 is attached to the upper end portion of the dropping shaft 21. The screw portion 28a on the inner peripheral side of the support tube 28 is screwed into the screw portion 21a of the dropping shaft 21, and the support tube 28 is configured to be vertically adjustable with respect to the screw portion 21a.

  The upper end of the vertically moving arm 25 is pivotally supported on the frame portion 24 of the rice washing portion 3 by a left and right shaft 25a, and the support cylinder 28 is supported by a fitting support portion 25a on the lower side of the vertically moving arm 25. The left and right side surfaces of the planar configuration are fitted and supported, and the mounting bolt 26 is supported in a support groove along the longitudinal direction of the fitting support portion 25a.

  A lock nut 27 is screwed above the support tube 28 of the screw portion 21a of the dropping shaft 21, and a washer 29 is screwed below the support tube 28 of the screw portion 21a. The dropping shaft 21 is rotated forward and backward about the vertical axis by the handle 23 to vertically adjust the support cylinder 28 with respect to the dropping shaft 21, and the lock nut 27 is screwed in to adjust the lower side of the lock nut 27 and the upper side of the washer 29. Thus, the support cylinder 28 is pressed and supported, and the adjustment position of the support cylinder 28 with respect to the dropping shaft 21 is adjusted and regulated. The upward rotation of the vertical movement arm 25 is regulated and regulated by the regulation bolt 30.

  Further, the vertical movement arm 25 is moved up and down by the dropping motor 52 and the dropping shaft 21 and the dropping valve 22 are moved up and down to open and close the lower opening of the rice washing tank 11, and the rice and water in the rice washing tank 11 are removed from the rice cooker 4. Can be dropped and supplied.

  According to the said structure, the up-and-down adjustment range of the support cylinder 28 with respect to the dropping shaft 21 can be lengthened, and even if the packing of the dropping valve 22 is compressed and deformed, the corresponding adjustment can be sufficiently performed, and the dropping operation is performed while facilitating the adjusting operation. The durability of the valve 22 can be increased.

Next, another embodiment of the filter 41 attached to the lower part of the rice washing tank 11 will be described with reference to FIG.
As shown in FIG. 6, the lower end outer peripheral portion of the conical tank 11b of the rice washing tank 11 has a plurality of holes through which water is allowed to pass without passing rice, and the lower side is provided with a small-diameter cylindrical filter 41. It is fitted and fitted from the center. For example, three triangular plates 42 for positioning are attached to the lower outer peripheral portion of the filter 41 at predetermined intervals.

  With the filter 41 fitted and fitted to the lower part of the conical tank 11b, the jacket 15 is attached to the lower part of the conical tank 11b. The bottom surfaces of the triangular plates 42,... Support the center of the bottom surface of the jacket 15, and the vertical center lines match, preventing the filter 41 from wobbling and being attached in a stable state.

  When the filter 41 is provided at the lower end portion of the conical tank 11b of the rice washing tank 11, as shown in FIG. 6B, a large number of small holes 43 are provided at the lower end portion of the conical tank 11b. Three triangular plates 42 for positioning may be attached to the lower outer peripheral portion of the tank 11b.
