AUTO-RICE WASHING DEVICE

TECHNICAL FIELD The present invention relates to an auto-rice washing device, and more particularly, to an auto-rice washing device for determining the amount of rice or bean that is to be cooked or the washing number thereof according to an input value, automatically washing rice, automatically supplying water tailored for cooking, and cooking rice. These days a home network market has been steadily promising owing to an expansion in digital home appliances, an increase in a customer's desire for living convenience such as home entertainment, home automation, home security, and the like, and a development of various wireless and wired network technologies.

In particular, it is expected that digital home promotes an embedded system optimized to networking and convergence and spreads all over upcoming ubiquitous society.

The embedded system, which refers to an operating system embedded in an electronic product other than a computer, is implanted in various types of electronic products and controls hardware. Under these circumstances that a computing element is mounted from an electronic calculator to a washing machine and a refrigerator, the embedded system is regarded as a core technology starting a new computing era.

As one of embedded systems, an auto cooking device suitable for a ubiquitous era has been developed. In particular, it is important to develop an auto-rice washing device with regard to an auto-rice washing process that is a core technology of a cooking device in order to realize the auto cooking device.

Although a conventional auto cooking device has been developed so as to satisfy the necessity, since the conventional auto cooking device is a semi-auto cooking device, it is difficult to automate a rice washing process that is a pre-cooking process, which is manually performed mostly dependent on a manpower. Such rice washing process is semi-manually performed by taking rice out of a rice box, putting the rice in a rice washing device, washing the rice, and carrying the washed rice into a rice cooker via a tool. Therefore, devices for automatically washing and cooking rice have been suggested in order to resolve various problems caused by a conventional manual rice washing process and conventional semi-manual rice washing process, for example, "Auto Semi-Rice Cooker" disclosed in Japanese Laid-Open Patent No. 1991-176007 (published on July 31 , 1991 ), "Semi-Rice Cooker" disclosed in Japanese Laid-Open Patent No. 1992-54919 (published on February 21 , 1992), "Automatic Electric Rice Cooker" disclosed in Korean Laid-Open Patent No. 1994-13433 (published on July 15, 1994), "Automatic System Rice Cooker" disclosed in Korean Patent No. 292039 (published on March 19, 2001 ), "Automatic Rice Cooker" disclosed in Korean Registration U. M. No. 318997, and the like.
