  • 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: 10427498
    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.

  • Patent number: 9950589
    Abstract: A vehicle air conditioner includes a blower for blowing air into a space of a vehicle compartment, and an air-conditioning mode switching portion for switching between air conditioning modes. The air conditioning modes include a normal air conditioning mode in which air conditioning of a specific region including a driver seat and air conditioning of a non-specific region not including the specific region in the space of the vehicle compartment are performed, and a specific-region prioritizing air conditioning mode in which an air conditioning capability for the non-specific region is decreased as compared to the normal air conditioning mode. The air-conditioning mode switching portion adjusts the air conditioning capability for the non-specific region based on a pressure of air drawn into the blower, in the specific-region prioritizing air conditioning mode.

  • Patent number: 9827826
    Abstract: When an air conditioning ECU determines that it is immediately before idling stop, the air conditioning ECU implements a front seat air conditioning mode even if the air conditioning ECU determines that an occupant intensive air-conditioning mode can be implemented. Accordingly, the air conditioning ECU controls opening and closing mechanisms so as to blow a conditioned air from driver's seat side outlet ports, and also blow the conditioned air from a passenger's seat side foot outlet port. Hence, in cooling operation, since a temperature increase of air drawn into an inside air inlet port is limited when the idling stop is carried out, temperature increase of air blown into the vehicle interior from the outlet port can be restricted. In other words, a temperature change in the vehicle interior can be limited when a travel engine stops due to the idling stop.

  • Patent number: 9769879
    Abstract: A radiation heater apparatus has a plurality of heat radiation parts and a plurality of heating parts. A low thermal conductive part is formed between adjacent two of the heat radiation parts. The low thermal conductive part is provided with resin material which mainly forms a substrate part. The low thermal conductive part thermally isolates the heat radiation part by surrounding a periphery of the heat radiation part. As a body contacts with the surface of the apparatus, the thermal energy of specific heat radiation part directly under the body dissipates heat to the body. Furthermore, heat transfer from the periphery of the specific heat radiation part to the specific heat radiation part is reduced by the low thermal conductive part.
