PURPOSE: A pressure rice cooker with a lid rotation locking device is provided to prevent rotation of a cover if steam pressure remains in a body by sealing the body and a cover with a silicon packing and mechanically fixing with protrusions and insertion grooves. CONSTITUTION: A pressure rice cooker with a lid rotation locking device comprises a body, a cover, and a silicon packing. The silicon packing is interposed between the body and the cover. Multiple insertion grooves are formed on the top of the body. Multiple protrusions are formed under the silicon packing corresponding to the insertion groove. If steam pressure remains in the body, the protrusions are hung on the insertion grooves, thereby the rotation of the cover is prevented even if users forcibly rotate the cover. |
