Abstract

PURPOSE:To remove rice bran and impurities attaching to the vicinity of an outflow port by jet water from a water outflow nozzle so as to smooth the outflow of water from the outflow port by making the outflow direction of the water outflow nozzle for feeding water into a rice washing receptacle opposite to the outflow port. CONSTITUTION:A water outflow nozzle 18 is disposed above a rice washing receptacle 1 and adapted to feed water into the rice washing receptacle through a cavity 12. The forward end of the above nozzle is opposite to an outflow port 9 with a gradient so that a jet water is brought into contact with a filter 10, and the optimum angle thetaof inclination of the water outflow nozzle 18 is 57 deg. to 60 deg.. Usually a bottom cover 2 closes the bottom portion of the rice washing receptacle 1, a designated amount of rice is dropped from the cavity 12, and water is allowed to flow out from the water outflow nozzle 18 to be jetted obliquely to the filter 10 of the outflow port 9, so that the water circulates in the rice washing receptacle without adhesion of rice bran to the filter 10. After the lapse of designated time, a plunger 16 is operated to turn an movable arm 15, whereby a valve element 13 is moved to open the outflow port 9, so that the impure water is allowed to flow out to the outside through a drainage pipe 17.

According to the publication, the rice washing device of a fully automatic rice cooker performs the rice washing operation automatically without the user checking the inside of the device, so if an abnormality occurs in the rice washing device, water may overflow from the rice washing container. There were disadvantages such as short-circuit accidents and inability to wash rice thoroughly. To be more specific, rice bran and the like accumulate at the outlet during or after washing the rice and prevent drainage from the outlet, and in the worst case, the outlet is blocked and water overflows.
