Title:
INDUCTION HEATING COOKING APPLIANCE
Document Type and Number:
Japanese Patent JP3861759
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an induction heating cooking appliance capable of precisely controlling the rotation number of a cooling fan by a simple constitution.
SOLUTION: The induction heating cooking appliance has a first control means 15 for controlling a first inverter circuit, a second control means 19 for controlling a second inverter circuit, and the cooling fan 20 for cooling the first and the second inverter circuits. A structure to change the rotation number of the cooling fan 20 is composed of only a driving circuit by the first control mean because the first control mean changes the rotation number of the cooling fan 20 according to information inputted from the second control means 19. Thus, the fan rotation number can be precisely controlled in multiple stages by a simple constitution.
