Abstract: The heater device is provided with a heater main body, and radiates radiant heat from the heater main body toward an object. The heater main body includes a sheet-like heat generating layer that generates heat and radiates the radiant heat, and a sheet-like heat insulating layer that is disposed on the side opposite to the object of the heat generating layer. The heat insulating layer has a sheet-like first layer having voids and a sheet-like second layer having voids arranged side by side in a thickness direction of the heat insulating layer with respect to the first layer. A porosity of the second layer is higher than that of the first layer.

Abstract: A heating part of this radiant heater has a plurality of heating wires. The plurality of heating wires are connected in parallel such that a plurality of parallel groups may be formed by electrodes. Further, the plurality of parallel groups are connected in series by the electrodes. The heating parts are set to reach a radiation temperature for emitting the heat radiation which makes a human to feel warmth. The heating parts have a thermal resistance in a longitudinal direction which is set, when an object contacts on the surface, a temperature of the part where the object touches falls to a suppressed temperature lower than the radiation temperature. The temperature of the heating part increases rapidly in response to electric supply. When there is a contact with an object, the temperature of the heating part decreases rapidly.

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: A heater device for warming a user has a heater panel including a planar heating element which generates heat by energization, a first heat radiation surface formed on one surface side of the heating element, and a second heat radiation surface formed on the other surface side of the heating element. The temperature of the first heat radiation surface is higher than the temperature of the second heat radiation surface. In the heater panel, the first heat radiation surface is configured as a non-contact heater that warms the user in a non-contact manner, and the second heat radiation surface is configured as a contact heater that warms the user in a contact manner.

Abstract: A heating apparatus has a heater body and a heater case. The heater body has a heat generator and emits heat supplied from the heat generator. The heat generator generates the heat when being energized. The heater case houses the heater body and is arranged on a side of an air-bag device for a vehicle adjacent to a vehicle compartment. The heater case is attached to an interior member located in the vehicle compartment or is a part of the interior member. The heater case has an expansion permissive portion that permits the air-bag device to expand into the vehicle compartment. The heat generator includes a portion located at a position corresponding to the expansion permissive portion. The heater body has a low strength portion that has a low strength as compared to the portion of the heat generator and that is located outside the expansion permissive portion.

Abstract: A heating system for a vehicle includes: a heater for non-contact heating that emits radiation heat by heat supplied from its heat generating part, which generates heat upon energization, to give warmth to an occupant in a state where a body of the occupant is not in contact with the heater; a heater for contact heating that generates heat upon energization to give warmth to the occupant in a state where the body of the occupant is in contact with the heater; and a control device that controls operations of the heater for contact heating and the heater for non-contact heating. The control device adjusts a heating output provided by the heater for contact heating and a heating output provided by the heater for non-contact heating, and controls the operations. Therefore, the occupant can enjoy a sense of heating that is not stereotypical, and achieve energy saving.

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.
