<p><P>PROBLEM TO BE SOLVED: To effectively prevent water from infiltrating inside by eliminating a defect caused by conventional high-frequency welding by joining a lid body attachable to and detachable from a rice cooker body, by vibration welding. <P>SOLUTION: The lid body 2 in the electric rice cooker including the lid body 2 attachable to and detachable from the rice cooker body 1 is constituted to form a sealed space 27 inside by connecting an upper plate 15 and a lower plate 16 both made of synthetic resin, by joint parts 25, 26 based on vibration welding, and a heat insulating material 28 and a metallic heat reflecting member 27 are disposed in the sealed space 27 to eliminate a fall in the degree of welding. Durability is considerably improved, and the infiltration of water inside is eliminated when the lid body 2 is washed in water while minimizing heat radiation from the lid body 2 to improve energy-saving performance. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
