An air-sending device includes a propeller fan to rotate about a rotational axis, and a ducted bell mouth surrounding an outboard area of the propeller fan. The propeller fan includes a plurality of blades. Each of the blades includes, in its outboard portion, a reflexed part bent upstream of an airflow that is generated in the direction of the rotational axis by rotation of the propeller fan. In the propeller fan, within an area that is closer to the trailing edge than is the near mid-chord area, the propeller fan is inclined downstream of the airflow from the inboard edge to the reflexed part. In at least a portion of an area where the cylindrical part of the bell mouth and the outboard edge of each blade face each, the reflexed part has a reflex angle of greater than or equal to 90 degrees.

Air-sending device

A multiblade fan includes an impeller including a rotating plate and blades and further includes a fan casing having a circumferential wall and a first end face disposed adjacent to distal ends of the blades. The first end face has an inlet. The multiblade fan further includes a duct and a flow regulating block disposed on an inner surface of the first end face. The flow regulating block regulates a flow of the air. The duct includes a diffuser plate. The circumferential wall includes a tongue that is connected to the diffuser plate. The first end face has a bell mouth provided at the inlet. The flow regulating block is spaced from the circumferential wall and extends along the bell mouth in the rotation direction such that the flow regulating block is located in a range of 120 degrees from a reference position on a line connecting the rotary shaft to a tip of the tongue.

Multiblade fan

A centrifugal fan includes: an impeller driven by a drive motor to rotate; a scroll casing including an inlet-port face having an opening and a wall portion having positions at which distances from an axis line that is a rotation center of the impeller differ from each other, and changing an air flow in a centrifugal direction generated by rotation of the impeller into an air flow in one direction; an air admitting portion including a bell mouth portion having a large-diameter side end placed on an inlet-air-flow upstream side of the inlet-port face; and a protruding portion extending from the air admitting portion in a direction orthogonal to the axis line, which is the rotation center of the impeller, and in a direction away from the rotation center and surrounding part of the bell mouth portion.

Centrifugal fan and ventilation fan

An axial flow fan has a boss portion rotationally driven by a motor; a plurality of rotary blades extending radially from a periphery of the boss portion and configured to force air to flow in a direction of a rotation axis of the motor; and a bellmouth accommodating the plurality of rotary blades, the bellmouth comprising a suction-side round portion having a curved surface expanded in a radial direction of the bellmouth, and a discharge-side round portion having a curved surface expanded in the radial direction of the bellmouth, the plurality of rotary blades each being entirely inclined to have an outer peripheral portion in a downstream side in an airflow direction, entirety of the outer peripheral portion being located on the downstream side in the air flow direction with respect to the suction-side round portion.

Axial flow fan

An air-conditioning apparatus includes refrigerant systems that each include an outdoor unit and indoor units and that air-condition a single room, and circulators for making a temperature distribution in the room uniform. The air-conditioning apparatus determines a load on each of the two refrigerant systems in operation, and, if it is determined that improvement of operating efficiency is possible on the basis of the determination result, performs a system-selective operation in which operation of one of the refrigerant systems determined to be under a low load is stopped and the other refrigerant system determined to be under a high load is selectively performed, and causes the circulators to transport blown air blown from the indoor units of the refrigerant system determined to be under a high load to an air-conditioned zone of the refrigerant system determined to be under a low load.

Air-conditioning apparatus

An axial flow fan improves air capacity and static pressure characteristics, and can ease stress at a leading edge portion of a blade base, even when a shape for noise reduction is adopted. An axial flow fan includes a boss portion and rotor blades. A rotor blade is segmented into a first area extending from the boss portion toward the outer peripheral side, and a second area connected to the first area and extending from the first area to the outermost periphery of the rotor blade. The distribution of a forward sweep angle varies quadratically in the first area, and the maximum forward sweep angle in the first area is not larger than the forward sweep angle in the second area. The distribution of chord-pitch ratio varies in a curved manner from the base as the minimum value in the first area, and is linear in the second area.

The aluminum-zinc plated steel sheet according to the present invention includes a plated steel sheet and a covering film that covers the plated steel sheet. The covering film contains a basic compound of transition metal other than cobalt and chromium, and metallic cobalt, or metallic cobalt and a cobalt compound. An amount of the covering film per one side is within a range of 0.01 to 0.8 g/m. An amount in terms of mass of transition metal other than cobalt in the covering film per one side of the plated steel sheet is within a range of 4 to 400 mg/m. An amount in terms of mass of cobalt in the covering film per one side of the plated steel sheet is within a range of 0.1 to 20 mg/m.

To provide a hand dryer that is capable of reducing the amount of noise without reducing the drying performance, and is capable of preventing foreign substances from entering from an air outlet thereof. A hand dryer is configured to blow water off hands with airflow emitted from nozzles. The hand dryer includes a hand insertion section that is open toward the outside, and the nozzles disposed on wall surfaces of the hand insertion section. A nozzle hole at the distal end of each of the nozzles is a wave-shaped slit.

Hand dryer

A surface-coated aluminum and zinc plated steel sheet in accordance with the present invention includes: a plated steel sheet; a composite coating film formed by applying an aqueous surface treatment agent on the plated steel sheet and drying the aqueous surface treatment agent. The aqueous surface treatment agent contains a water dispersible resin (A), a cobalt compound (B), and water, and has a pH within a range of 7.5 to 10. The composite coating film contains the water dispersible resin (A) and the cobalt compound (B). A percentage by mass of the water dispersible resin (A) in the composite coating film is 90% or more. A mass of the composite coating film per one surface of the plated steel sheet falls within a range of 0.5 to 3.5 g/m.
