Abstract: A radiation heating device includes: a planar heat generation layer; a heat generation portion that is provided in the heat generation layer and that generates heat by energization; a plurality of heat radiation portions that are disposed in the heat generation layer and that radiate heat transferred from the heat generation portion; a low heat conduction portion that is provided around each of the heat radiation portions and that has a lower heat conductivity than the heat radiation portions; and a contact detection unit that detects contact of an object with the heat generation layer. The radiation heating device further includes an energization amount decrease unit that decreases an energization amount of the heat generation portion when the contact detection unit detects the contact of the object with the heat generation layer.

Abstract: A radiant heater device radiates a radiation heat when a current is applied to a heat generating part having a flat shape. The radiant heater device has a cover and a supporting member. The cover is arranged in a direction in which the radiation heat is radiated and covers the heat generating part. The supporting member supports the cover. The cover is made of a material having a greater infrared transmissivity relative to the supporting member.

Abstract: An in-vehicle radiant heater control apparatus includes: a temperature detection device for a heater in a vehicle compartment; a first switch element connected in series to the radiant heater between a power supply and a ground; a temperature control device controlling the first switch element that the heater temperature approaches a target temperature; a resistive element having one electrode connected to one electrode of the heater; an inter-electrode voltage detection device for the resistive element; and a resistance calculation device repeatedly obtaining a heater resistance of the radiant heater based on a voltage between the other electrode of the resistive element and the other electrode of the heater, a detected resistance voltage, and a resistance of the resistive element. The temperature detection device obtains the heater temperature based on the heater resistance.

Abstract: A heater control device controls an electric heater which includes a plurality of heat generating portions. The heater control device determines whether a total energization current value, which is a current value to be supplied to the electric heater when all of the plurality of heat generating portions are energizable, exceeds a predetermined current limit value. The heater control device is configured to, when it is determined that the total energization current value exceeds the current limit value, energize the electric heater while switching, among any or all of the plurality of heat generating portions, those to be turned to a non-energizable off state.

Abstract: The air-conditioning control device is configured to control an air conditioner for a vehicle having a radiant heater and to output a cancel signal that allows an engine, which has been stopped in response to an idling stop control, to restart. The radiant heater is configured to generate radiant heat to heat an occupant in a compartment of the vehicle. The air conditioner is configured to heat an interior of the compartment using engine cooling water. The air-conditioning control device stops the engine in response to the idling stop control. The air-conditioning control device outputs a cancel signal allowing the engine to restart following the engine having been stopped such that an idling stop time is longer when the radiant heater is operated than when the radiant heater is not operated.

Abstract: A heater device includes: a distance specifying portion that specifies a distance between a sensing subject, i.e., an occupant and a heater main body as a sensed distance; and a moving mechanism that moves the heater main body. The heater device further includes a heater position control portion that controls the moving mechanism such that the distance between the sensing subject, i.e., the occupant and the heater main body is adjusted to a target distance based on the sensed distance, which is specified by the distance specifying portion.

Abstract: A heater is installed indoors and heated to a target temperature. The heater is controlled by a controller. The controller has a regular control module which heats the heater to reach the target temperature. In addition, the controller has a suppressive control module which heats the heater to a suppressed temperature lower than the target temperature by electric power suppressed so that surface moisture adhering on the surface of the heater is decreased. When an activation of the heater is ordered, the heater is heated by the suppressive control module, after that, the heater is heated by the regular control module. The surface moisture is decreased by the suppressed temperature. Therefore, generating rapid boiling and/or rapid evaporation of the surface moisture by the target temperature may be suppressed.
