And a controller to operate.

Action According to the above configuration, when the rice and the water to the extent that the upper surface of the rice is soaked are put in the rice washing tank and the rice washing tank is rotated at a low speed by the control of the controller, the rice becomes the surface of the rice by the action of the promoting member for promoting the rice washing. The bran, rice flour, dirt, etc. (hereinafter referred to as bran, etc.) adhering to the are removed. Next, when the rice washing tank is controlled to rotate at high speed (to the extent that rice does not jump out), it is centrifugally dehydrated,
At this time, rice bran and the like also flow out together with water, and rice can be cooked.

EXAMPLE An example of a rice washing machine of the present invention will be described below with reference to FIGS.

In the figure, reference numeral 1 is a rice washing machine main body, which is equipped with a motor 2 in the lower part and a rice washing tank 3 in the upper part, and an upper lid 4 is provided on the upper surface of the main body 1. The rice washing tank 3 is detachably connected to the motor shaft 5. In addition, a cavity 6 is provided in the outer peripheral portion of the upper end of the rice washing tank 3, and a liquid is enclosed therein, and this liquid is
Automatically adjust the unbalance during rotation of the rice washing tank 3. Reference numeral 7 denotes an accelerating member for accelerating the washing of rice, which is provided inside the washing tub 3. In the embodiment, the accelerating member is composed of a flexible spatula and can rotate around a fulcrum 8 provided on the upper lid 4. It can face the wall. A changeover switch 15 is provided near the fulcrum 8 so that the changeover switch is activated when the accelerating member 7 is rotated. Further, as shown in FIG. 2, when the promoting member 7 is opposed to the inner wall surface of the rice washing tank 3,
The facilitating member 7 is arranged so as to be opened at a certain angle with respect to the inner wall surface. Reference numeral 9 is an inlet for putting rice and water, which is provided on the upper lid 4. The upper lid 4 can be opened and closed with respect to the rice washing machine body 1 by a hinge 10. 11 is a water pan, and after washing rice in the rice washing tank 3, centrifugally dehydrated water is a water pan 11
And collects in the drainage container 13 placed under the drainage hole 12 through the drainage hole 12. Reference numeral 14 denotes a controller which is switched by a changeover switch 15 and controls the motor 2 so that the speed is low at the time of washing rice and high at the time of dehydration after washing.

Next, the operation of the rice washing machine having the above structure will be described. First, rice is put into the washing tank 3 through the inlet 9, and then water is added so that the upper surface of the rice is soaked.
About 100 c.c. of water for 0 c.c. The operation of the controller 14 is shown in FIG. 3. When the accelerating member 7 is stood and faces the inner wall surface of the rice washing tank 3 (solid line state in FIG. 1), the changeover switch 15 is turned on and the rice washing tank 3 rotates at a low speed. The rice is pressed against the inner wall surface of the rice washing tank 3 by the accelerating member 7, and at this time, the rice comrades rub against each other to remove bran and the like from the rice grains and mix in the water. The controller 14 has a timer circuit to set a time for rotating the rice washing tank 3 at a low speed, that is, a rice washing time. Therefore, the rice washing process is completed in tens of seconds. Next, when the accelerating member 7 is rotated and stored in the lower surface of the upper lid 4 as it was originally (state of broken line in FIG. 1), the changeover switch 15 is changed over to start the dehydration step. Here, the rice washing tank 3 rotates at a high speed, the water mixed with the bran or the like is centrifugally dehydrated at a stretch, and the bran or the like is also discharged together with the water and collects in the drain container 13 through the drain hole 12. When the rice washing tank 3 starts to rotate at a high speed, the liquid enclosed in the cavity 6 at the outer periphery of the upper end of the rice washing tank 3 moves to a position where the rotation imbalance of the rice washing tank 3 is corrected, and acts as an auto balancer. The rice washing process is controlled by the controller 14, and the rice washing tank 3 is stopped after rotating for a set time. After washing the rice, the upper lid 4 is opened, the rice washing tank 3 is taken out, and the rice in it is transferred to the rice cooker.

The above is the operation of the rice washing machine of the embodiment of the present invention. In the embodiment, rice and a small amount of water are put in the rice washing tank 3 and rotated at a low speed, and the promoting member 7 puts the rice on the inner wall surface of the rice washing tank 3. By pressing, rice comrades rub against each other and the rice bran and the like are taken out of the rice grains and mixed in the water, and then the rice washing tank 3 can be rotated at high speed and centrifugally dehydrated to remove the bran and the like together with the water. As a result, the rice can be washed in a very short time, and the bran and the like can be discharged together with water in a short time due to the centrifugal force. Less. The accelerating member 7 may be a simple rod-shaped member instead of a spatula as in the embodiment. After dehydration,
There is no problem even if the amount of water necessary for cooking rice is put in the rice washing tank 3 and then moved to the rice cooker. Further, although the changeover switch 15 is interlocked with the facilitating member 7, it may be one which can be operated independently.

Effects of the Invention As described above, the rice washing machine of the present invention removes the bran and the like adhering to the surface of rice by the rotation of the rice washing tank and the action of the rice washing promoting member, and then the rice washing tank is rotated at high speed to remove the bran and the like. The rice is discharged together with the rice so that it can be cleaned, so that it has no need of time and effort, and it has the outstanding effect of cleaning rice with a small amount of water. Is.
