  • Patent number: 10493822
    Abstract: A radiant heater device includes: a heater main body having a heating portion that generates heat by being supplied with electric power to radiate radiation heat due to the heat supplied from the heating portion; an output control unit that controls an output of the heating portion; and a maximum output determination unit that determines an upper limit of the output of the heating portion depending on a heat load around the heater main body. The output control unit controls the output of the heating portion depending on the heat load not to exceed the upper limit of the output determined by the maximum output determination unit.

  • Publication number: 20190359032
    Abstract: A radiant heater device has an electrode embedded in a substrate part and a plurality of heating parts. The electrodes are formed by material that has low specific resistance. An area occupied by the electrode is restricted. The heating parts are formed by material having high specific resistance in order to generate heat so that radiation is produced. The electrode and the heating part are electrically connected within the substrate part. The plurality of heating parts are arranged in parallel between a pair of electrodes. The electrodes and the heating parts are formed in a film-like shape, and the thermal capacity is reduced. As a result, a temperature of the heating parts rises promptly in response to a turning on of power. In addition, the temperature of the heating parts promptly decreases when an object comes into contact therewith.

  • Patent number: 9873309
    Abstract: A radiant heater air-conditioning system includes: a heater main body having a heating portion energized to generate heat so as to radiate a radiant heat into a vehicle interior; an energization setting unit that sets an energization enable state for enabling energization of the heating portion and an energization disable state for disabling the energization of the heating portion; and an air-conditioning control apparatus that controls an air-conditioning output of a heating operation in the vehicle interior. The air-conditioning control apparatus reduces the air-conditioning output when the energization enable state is set, compared with when the energization disable state is set.

  • Patent number: 9381789
    Abstract: A heater apparatus includes a main body, a detecting unit, and a control part. The main body has a power supply part to which electric power is supplied and a heating portion connected to the power supply part to generate heat by electric power supplied from the power supply part. The detecting unit detects an object around the main body. The control part controls supply amount of the electric power to the power supply part. The control part controls the supply amount of electric power to the power supply part to be reduced compared with a normal state when the detecting unit detects that the object is within a predetermined range of the main body.
