<p><P>PROBLEM TO BE SOLVED: To efficiently cool a protective frame and electromagnetic induction coils and to suppress a temperature drop in a cooker body. <P>SOLUTION: The electric rice cooker includes a rice cooker body 1 made of a nonmetallic material and detachably holding an inner pot 3 with induction heating elements 9A, 9B provided at a bottom face and a curved face located between the bottom face and a side face. The bottom part electromagnetic induction coil 15A is disposed in a space 19 surrounded by the bottom part of the protective frame 8 and a coil die 16, and a cooling fan 25 having an upward ejection port 25a is disposed at the inner bottom part of the rice cooker body 1. A control substrate 27 with electronic components disposed is raised in a position that divides the ejection port 25a of the cooling fan 25, while interposing an air flow space between itself and the protective frame 8, and air guide means 34 is provided for guiding a part of cooling air W from the cooling fan 25 into the space 19 to efficiently cool the protective frame 8 and the electromagnetic induction coils 15A, 15B and to suppress the temperature drop in the rice cooker body 1. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
