Abstract
A heating cooker of the present invention includes a plurality of light emitting indicator units. The light emitting indicator units each have a temperature sensing unit that senses an ambient temperature of a light emission source. Therefore, deterioration of the light emission source of each of the light emitting indicator units can be suppressed to realize a further reduction in thickness, and to improve visibility of the indicator sheet.
Claims10
A heating cooker, comprising:
- a box-like body having an opening at a top portion of the body;
- a top board that is provided over the opening of the body;
- a heating unit that is provided inside the body and that is configured to heat a heating target cooking vessel placed on the top board;
- a plurality of light emitting indicator units that are provided inside the body beside the heating unit;
- and
- a control unit in communication with and configured to control the heating unit and the light emitting indicator units,
- wherein
- the light emitting indicator units each comprise:
- a case having an opening at a top portion of the case facing the top board;
- a light emission source located inside the case;
- a temperature sensing unit located inside the case and configured to sense an ambient temperature of the light emission source;
- and
- an indicator sheet positioned on top of the case to close the opening of the case, wherein the indicator sheet comprises:
- a light transmitting portion that passes light of the light emission source;
- and
- a light blocking portion that is provided at a position farther away from the heating unit than the light transmitting portion in a lateral direction in a common plane and that is provided directly above the light emission source in a height direction that is perpendicular to the lateral direction, the light blocking portion blocking the light of the light emission source.
