Parts are arranged in the vertical direction. The rice washing section,
A vertical cylinder shaft having a stirrer is rotatably supported at the upper part of the rice washing tank, and a valve stem is inserted into the vertical cylinder shaft so as to be able to move up and down freely. A rice valve is provided, and a lifting mechanism for raising and lowering a valve rod is disposed above the rice washing tank.

The elevating mechanism has a link that swings by engaging with the upper end of a valve stem, a cam that contacts the link, and a rice discharging motor that rotates the cam about a horizontal axis. The structure is such that the link swings with a cam and the tip of the valve stem rises and descends greatly.

[0004]

In the above prior art, a valve stem protruding upward from an upper portion of a rice washing tank is raised and lowered by an elevating mechanism, and a tip of a link engaged with the valve stem is a valve stem. Because it has a structure that raises and lowers even more, it is necessary to form a large space for raising and lowering mechanism above the rice washing tank, and the ceiling height of the rice processing machine is increased and the capacity of the rice washing tank is reduced. This is an obstacle to making rice processing machines compact. By the way, when the upper surface of the housing is to be used as a cooking table, taking a large space above the rice washing section is a large bottleneck in securing a necessary and sufficient rice washing capacity.

[0005] It is an object of the present invention to provide a rice processing machine for cooking rice which can solve such problems of the prior art. The present invention uses a tow line for opening and closing the rice discharging valve, and by changing the horizontal position of a tow body provided at the tip of the tow line above the rice washing tank, creates a large vertical space above the rice washing tank. An object of the present invention is to provide a rice processing machine for cooking rice that can open and close a rice discharging valve without forming the rice processing valve.

[0006]

A first concrete means for solving the problem in the present invention is to provide a rice discharge valve 24 for opening and closing a rice discharge port 20a below the rice washing tank 20, and the rice discharge valve 24 is provided.
