More Information
Summary:A radio-frequency heating apparatus with a range hood includes: a radio-frequency heating device having a range hood; a plurality of lighting lamps (41 42) for lighting under the radio-frequency heating device; and dimming device (49) provided with TRIAC (44) for controlling luminance of lighting lamps (41, 42), wherein the plurality of lighting lamps (41, 42) are connected in series. With this arrangement, even if a short-circuiting failure occurs in one of the lamps, the inside resistance of the other lamp can restrict a short-circuiting current, thereby preventing an overcurrent from flowing in dimming device (49) during short-circuit.
