  • Patent number: 11945285
    Abstract: The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

  • Publication number: 20210245575
    Abstract: An airflow generating device includes an airflow generating portion, a duct, and a controller. The airflow generating portion is configured to generate an airflow. The duct is configured to guide the airflow to a blowing outlet through which the airflow is blown out toward a passenger in a vehicle cabin. The controller is configured to cause the airflow to be intermittently blown out through the blowing outlet by controlling a frequency of a pulse voltage applied to the air flow generating portion and a duty ratio of a pulse width to a pulse period of the pulse voltage. The controller is configured to control the duty ratio and the frequency of the voltage such that the airflow is blown out through the blowing outlet at a speed between a predetermined lower limit, inclusive, and a maximum lower limit, non-inclusive, which is greater than the lower limit.

  • Patent number: 10958133
    Abstract: In an electric motor, a magnetic bearing generates an electromagnetic force between multiple permanent magnets and a coil and rotatably supports an other side of a rotation shaft in an axis line direction. The rotation shaft is configured to be capable of being inclined with a rotation center line using a bearing side of the rotation shaft as a fulcrum. An electronic control device controls a current that flows to the coil such that an axis line of the rotation shaft approaches the rotation center line due to a supporting force which is the electromagnetic force between the multiple permanent magnets and the coil. Accordingly, the rotation shaft is rotatably supported to be freely rotatable by a magnetic bearing and the bearing.

  • Patent number: 10414248
    Abstract: A humidification device is used in a vehicle air conditioner having a cooler disposed in an air conditioning case. The air conditioning case has a ventilation path leading air into a vehicle compartment. The humidification device has an adsorber that absorbs and desorbs moisture, a blower, a door that opens or closes an air flow path, and a controller. The controller switches the air flow path by controlling the door to set (i) a dehumidification mode in which air cooled by the cooler is led to the adsorber, and moisture in the air is adsorbed by the adsorber or (ii) a humidification mode in which air is led to the adsorber, the moisture is moved from the adsorber to the air to humidify the air, and the humidified air is blown toward an occupant.
