Abstract: A centrifugal blower includes a centrifugal fan and a separation cylinder. The centrifugal fan has a separation plate. The separation cylinder is disposed inward of the blades in the radial direction of the centrifugal fan. The separation plate has an inner end surface extending from the one side to the other side in the axial direction at a position of an inner end in the radial direction. The separation cylinder has a separation cylinder end surface extending from the one side to the other side in the axial direction at a position of an end on the other side in the axial direction. A height of one of the separation cylinder end surface and the inner end surface in the axial direction is larger than a height of the other of the separation cylinder end surface and the inner end surface in the axial direction.

Abstract: A centrifugal blower includes: a centrifugal fan having plural blades arranged around a fan axis and a separation plate to blow out air in a radial direction after being sucked from one side in an axial direction; a fan casing housing the centrifugal fan; a partition plate that defines a first air passage and a second air passage arranged on the other side of the first air passage in the axial direction; and a separation cylinder arranged inside the plural blades in the radial direction. The separation cylinder expands in the radial direction as extending toward the other side in the axial direction, and is shaped to extend outward in the radial direction obliquely to the axial direction at the other end position of the separation cylinder positioned at the other end in the axial direction.

Abstract: A heater device includes an insulating base material, a heater wire, a temperature detection element, a line and a branch line. The heater wire is provided on the insulating base material, forms a path through which current flows when energized, and generates heat when energized. The temperature detection element is provided on the insulating base material and has an electrical characteristics that change according to temperature. The line is provided on the insulating base material and is electrically connected to the temperature detection element. The branch line is provided on the insulating base material, has one end connected to the heater wire and the other end not connected to the heater wire, and extends around the temperature detection element.
