    Abstract: An impeller includes a backing plate, a rim disposed so as to face the backing plate, and a plurality of blades arranged in a circumferential direction around a virtual rotation axis of the backing plate. Each of the plurality of blades has an inner circumferential end, an outer circumferential end a sirocco blade portion being forward-swept and including the outer circumferential end and having a blade outlet angle of larger than 90 degrees, and a turbo blade portion being swept-back and including the inner circumferential end, a first region located closer to the backing plate than a middle point in an axial direction of the rotation axis, and a second region located closer to the rim than the first region. Each of the plurality of blades is formed such that a blade length in the first region is longer than a blade length in the second region. In the first region and the second region, a ratio of the turbo blade portion in the radial direction is larger than a ratio of the sirocco blade portion in the radial direction.

    Abstract: An impeller includes: a main plate to be rotated; an annular side plate having a suction port for air; and blades in a circumferential direction. Each of the blades has: an inner peripheral end; an outer peripheral end; a sirocco blade portion that includes the outer peripheral end, and forms a forward-swept blade; and a turbo blade portion that includes the inner peripheral end and forms a swept-back blade. The blade has an end portion facing the suction port and a base portion connected to the main plate, and the end portion has a smaller thickness than that of the base portion in the sirocco blade portion. The end portion of the blade has a blade shape, and in the end portion having the blade shape, a first blade thickness of an inner circumferential side of the impeller is greater than a second blade thickness of the outer circumferential side.

    Abstract: A humidifier, including: a flat humidification member formed of a water absorbing member and arranged in an upright posture; a nozzle serving as a water supply unit configured to supply water to the humidification member; and an airflow direction changing plate arranged with a clearance secured between the airflow direction changing plate and the humidification member. On a flat surface of the airflow direction changing plate opposed to the flat humidification member, an airflow direction changing portion is arranged to project toward the flat humidification member, the airflow direction changing portion being configured to change a direction of an air current flowing between the flat humidification member and the airflow direction changing plate.

    Abstract: A centrifugal blower includes a fan including a main plate having a disk-shape, and a plurality of blades, and a scroll casing configured to accommodate the fan. The scroll casing includes a discharge portion and a scroll portion including a side wall, a circumferential wall, and a tongue portion. The circumferential wall includes a curved circumferential wall and a flat circumferential wall. In comparison with a centrifugal blower including a standard circumferential wall having a logarithmic spiral shape in cross-section perpendicular to a rotational shaft of the fan, in the curved circumferential wall, at a first end being a boundary between the circumferential wall and the tongue portion and at a second end being a boundary between the circumferential wall and the discharge portion, a distance L1 between an axis of the rotational shaft and the circumferential wall is equal to a distance L2 between the axis of the rotational shaft and the standard circumferential wall.
