[0004]

Although the above-mentioned conventional examples 1 and 2 have the same operational effects as described in the above-mentioned publication, in any of the water supply means, a common route for washing rice and water for adjusting water ( Water supply pipe). With a common water supply pipe, the amount of water used for washing and the amount of water added and subtracted from each other are different, which makes the water supply control cumbersome and saves much water. On the other hand, in order to improve the luster of cooked rice and to improve the cooking afterwards, mix rice cooking oil when cooking rice, and to improve the seasoning when making rice balls etc. , Oil, salt, etc. are collectively referred to as seasonings).

Conventionally, after the seasoning is put into a rice cooker, the rice is washed, the colander is raised, and the water is added (hereinafter referred to as the rice discharging process). The seasoning (additive) that was put in the rice cooker may stick to the bottom of the rice cooker or form a film during the time of this rice removal process. If such a phenomenon occurs, heat conduction during rice cooker may occur. Not only will the quality of the cooked rice deteriorate and the quality of the cooked rice will deteriorate, but the bottom of the rice cooker must be cleaned each time, especially if the rice cooker is equipped with a heat-sensitive member (heat-sensitive sensor). there were.

Therefore, it is considered that the seasoning can be added in the middle of the water supply route of the water supply means.
However, in the conventional examples 1 and 2, since the water supply pipe is commonly used for washing and adjusting the amount of water, if a seasoning is added to the water supply pipe to enter the rice washing process, the rice washing process may include polishing, rinsing, etc. As a result, the seasoning flowed out at the time of rinsing, and it was meaningless to add the seasoning. Therefore, according to the present invention, by dividing the route in the water supply means into the one for washing rice and the one for adjusting water, it is possible to accurately and easily control water supply and expect water saving, so that an appropriate amount of seasoning can be surely mixed into rice. It is an object of the present invention to provide such a rice washing device.
