Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic rice cooking device that automatically stores, weighs, washes, and cooks rice.

Conventional structure and its problems Conventionally, in this type of automatic rice cooking device, the rice bin is fixedly installed inside the device body, and rice can be added to the rice bin using a lid that is removably installed above the rice bin. This was done by opening the rice bin or by opening the door installed at the top of the side of the rice bin. However, in the case of a structure with a lid on the rice jar, there is a risk that dirt, dust, water, etc. may enter the rice jar through the gap between the rice jar and the lid, resulting in unsanitary conditions. The lid had to be opened and closed, so there were drawbacks such as not being able to place things on top of the lid at all times. Furthermore, if a door is provided at the upper side of the rice bin, the rice is introduced from the upper side of the rice bin, so the rice can only be introduced up to the lower end of the door, creating a dead space. In addition, it was difficult to fill the rice bin evenly, and the rice bulged up on the door side, making it difficult to insert rice into the rice bin.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides an automatic rice cooking device with improved operability.

Structure of the Invention The automatic rice cooking device of the present invention includes a rice bin having a rice input port at the top and a rice discharge port at the bottom; The device body is equipped with a rice measuring chamber having a discharge port, a rice washing device for washing the rice weighed in the rice measuring chamber, and a rice cooker for storing the rice washed by the rice washing device. It is slidably disposed on the main body and works in conjunction with the operation of a rotatable opening and closing plate that alternately opens and closes the rice discharge port of the rice bin and the rice discharge port of the rice measuring chamber, and the lower part of this opening and closing plate is connected to the rice measuring chamber. This device is equipped with a rice pot locking device that locks the rice pot inside the device body when the rice discharge port of the rice pot is open.
When putting rice into the rice jug, you can slide the rice jug out of the main body of the device and pull it out.On the other hand, when the automatic rice cooking device is operating, that is, when the lower part of the opening/closing plate is in the rice measuring chamber, the rice can be put in. When the discharge port is open, the rice bin is locked into the main body of the apparatus by the rice bin locking device, so that there is no possibility that the rice bin will be pulled out by mistake.
