BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window mechanism of a rice washing apparatus for automatically washing rice.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No.
There is an automatic rice cooker disclosed in Japanese Patent Publication No. 181113/1992, in which a rice storage unit for storing rice, a measuring unit for measuring and discharging the rice in the rice storage unit, and a rice discharged from the measuring unit via a stirring mechanism. The rice washer is provided with a rice washing section for washing the rice, and a rice cooking section for cooking the rice discharged from the rice washing section. A disk-shaped agitator is provided near the bottom of the rice washing section.

[0003]

In the prior art, there is a problem that the rice washing tank in the rice washing section has no window, and it is difficult to check and clean the internal stirring mechanism. This problem can be solved to some extent by forming an inspection window in the rice washing tank and providing a window cover for opening and closing the window. However, it is necessary to seal such a window lid so as not to cause water leakage, but it is difficult to provide a reliable and durable seal with a configuration that simply opens and closes the window lid. Problems arise.

In the present invention, a sealing material is provided on a window cover for opening and closing a window formed in a rice washing tank, and the window cover is pressed toward the rice washing tank to be closed, thereby ensuring the prevention of water leakage. It is an object of the present invention to provide a window mechanism of a rice washing device capable of improving durability.

[0005]

The concrete means for solving the problem in the present invention is to store the weighed rice and water in a rice washing tank 16 having a cylindrical upper part and a conical lower part. In a rice washing apparatus for washing rice while stirring, a window 70 is formed in a cylindrical portion of the rice washing tank 16 and a window cover 71 for opening and closing the window 70 is provided.
Is formed by adhering a sealing material 75 to the inner surface of a plate 72 having an arc-shaped cross section pivotally supported on one side of the rice washing tank 16, and washing the plate 72 between the other side of the plate 72 and the rice washing tank 16. That is, a fixing tool 76 for fixing the tank 16 while pressing it against the tank 16 is provided.

[0006] Thus, the rice washing section 5 is provided with a rice washing tank 16.
When the vertical axis 79 is rotated after the measured rice and water are put in the mixing device, the stirring means 17 rotates in the mixing device, and the rice is washed while stirring. When the window cover 71 is opened, inspection and cleaning of the stirring means 17 and the like become possible. When the window cover 71 is closed, the sealing material 75 comes into close contact with the outer surface of the cylindrical portion of the rice washing tank 16 to prevent water leakage. The window cover 71 has an arc shape in cross section. When the window cover 71 is fixed by the fixing member 76, the window cover 71 is pressed against the cylindrical portion of the rice washing tank 16, and the prevention of water leakage is enhanced.

[0007]
