PURPOSE: A rice cooker having a device for preventing an inner pot and a locking ring from being worn is provided to prevent fine powder from putting into the inner pot by preventing the wear due to the friction between the inner pot ant eh locking ring as the locking ring rotates or moves forth and back. CONSTITUTION: A rice cooker having a device for preventing an inner pot and a locking ring from being worn comprises an inner pot(120), an inner pot lid(130), a locking ring(110), and a wear preventing plate(140). The inner pot comprises a plurality of flanges(121) at constant intervals. The inner pot lid opens and closes the opening of the inner pot. The locking ring covers the flanges of the inner pot and the rim of the inner pot lid. The locking ring comprises a plurality of locking portions(114) corresponding to the flanges of the inner pot. While rotating along the flanges of the inner pot and the rim of the inner pot lid, the locking ring locks or unlocks depending on the relative location of the flanges to the locking portions. The wear preventing plate prevents the wear occurring between the flanges of the inner pot and the locking portions of the locking ring due to the rotation of the locking ring. |
