Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker for cooking rice by laying a net beforehand on a pot containing rice and water.

[0002]

2. Description of the Related Art A means for supplying rice and water directly to a rice cooker to cook rice is generally used.

[0003]

However, with the above-mentioned means, rice grains, glue, etc. adhered to the rice cooker, which required a great deal of labor to clean the rice cooker. In particular, since a large amount of rice is cooked in a rice cooker for business use per day, the operator's fatigue was very great. In order to reduce this labor, a means of supplying rice and water to a rice cooker that has been laid beforehand in a rice cooker to cook rice has been considered. By this means, the rice can be taken out by taking out the net, so that the rice grains can be prevented from adhering to the rice cooker and the rice cooker can be easily cleaned. However, if any of the factors (for example, the operator's carelessness) causes the net to cover the top of the rice layer that has been supplied and adheres to it, premature cutting (before the rice is cooked, the rice cooker switch turns "OFF"
It means that it becomes "F").

[0004]

The present invention provides a device for preventing pre-cooking in a rice cooker that does not cause troubles during rice cooking, and has taken the following technical means. That is, a net 2 provided with a mesh 1 through which rice does not pass
In the rice cooker for supplying rice and water onto the net to cook rice, a net receiver 3 is provided on the net to prevent the net 2 from contacting the upper surface of the rice layer. The device configuration.

[0005]

Operation: First, a net 2 provided with a mesh 1 through which rice does not pass is laid in a pot of a rice cooker. Next, the net receiver 3 is placed on the net at the bottom of the pot to supply rice and water. Then, the end portion of the net 2 is covered on the net receiver, and then the pot is covered and the rice cooking work is started. After that, when the rice cooking work is completed, the lid is removed and the net receiver 3 in the pot is taken out. Then, when the net 2 is lifted, the rice is also lifted while being wrapped in the net 2. Therefore, the worker transfers the rice from the net 2 to the next process such as a container or a molding machine.

[0006]

[Effect] When the rice is taken out, the rice does not adhere to the inner surface of the pot, so the pot can be washed easily and easily. Since all the rice can be taken out from the pot by lifting the net 2, the work time of the post-process (for example, supplying rice to the container) can be shortened. Further, since the end of the net 2 is supported by the net receiver 3, the net 2 does not directly cover the upper surface of the rice layer, and the quality of the rice can be prevented from being deteriorated due to premature cutting.
