A fan of which the blowing efficiency can be increased, the fan including a blade and a bell mouth. The blade rotates around a rotation axis that is along a first direction. The bell mouth includes a staircase structure positioned around the blade along a first plane perpendicular to the first direction. The staircase structure surrounds an opening that spreads toward a blowing direction of the blade.

A centrifugal fan includes a back plate, a shroud, and multiple blades. The multiple blades include first to third blades. The first to third blades include first to third leading edge parts and first to third trailing edge parts. First to third lengths are the length from the first to third leading edge parts to the first to third trailing edge parts. The second length is greater than the first length. The third length is greater than the second length. The numbers of the first to third blades are equal. The total number of the multiple blades is a multiple of 3, and is not less than 6. The first to third blades are arranged in a rotation direction in the order of the first blade, the second blade, and the third blade.

A drying device according to an embodiment dries a surface of an article by blowing hot air, and includes a drying chamber including a hot air supply port that blows the hot air, an infrared camera acquiring temperature distribution information that is information related to a temperature distribution inside the drying chamber, and a controller controlling a drying condition inside the drying chamber. The controller acquires corrected temperature distribution information by performing lock-in analysis of the temperature distribution information to remove noise from the temperature distribution information, and controls the drying condition based on the corrected temperature distribution information and based on a temperature distribution model that is a model related to the temperature distribution inside the drying chamber and is pre-generated using machine learning.

Drying device

An axial fan includes: an impeller including a rotating part, and a blade part connected to the rotating part; a bellmouth including a flat part orthogonal to an extension direction of a rotation axis of the rotating part; a rising part rising from the flat part; and an opening along which the rising part extends, the impeller being located in the opening, the rising part surrounding the impeller, the bellmouth including a plurality of grooves located at a surface of the bellmouth, the surface of the bellmouth being connected to an inner surface of the rising part, the inner surface of the rising part facing the blade part of the impeller, the plurality of grooves being located in at least a corner portion connecting the flat part and the rising part, the plurality of grooves extending in a direction crossing the flat part.

Axial fan

According to one embodiment, a rectifying plate is opposed to a plurality of nozzles which are configured to inject a fluid. The rectifying plate is configured to rectify the fluid. The rectifying plate includes: a plurality of high flow path resistance areas, and a low flow path resistance area. Each of the high flow path resistance areas includes a nozzle-facing area which is opposed to one of the plurality of nozzles. The low flow path resistance area surrounds each of the plurality of high flow path resistance areas. The low flow path resistance area includes a plurality of first through-holes to allow the fluid to pass through and having a smaller flow path resistance of the fluid than that of the high flow path resistance area.
