  • 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: 10272745
    Abstract: A humidifying device for a vehicle has a humidity detection part, a blower, a non-water-supply humidifier, and a controller. The humidity detection part detects a humidity in a vehicle compartment. The blower draws, as an intake air, an inside air in the vehicle compartment and an outside air outside the vehicle compartment at a specified ratio and blows the intake air toward the vehicle compartment. The non-water-supply humidifier collects water included in the inside air and supplies a humidified air, which is humidified using the water, toward a specified area in the vehicle compartment. The controller sets the specified ratio between the inside air and the outside air and controls an operation of the non-water-supply humidifier. The controller controls the blower to draw at least the inside air, when the non-water-supply humidifier is operated, and when a humidity in the vehicle compartment is lower than a specified humidity.
