Embodiment Construction

[0027] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. At this point, it should be noted that in the drawings, the same components are denoted by the same symbols as much as possible. In addition, detailed descriptions of well-known functions and configurations that are judged to obscure the gist of the present invention are omitted. For the same reason, in the drawings, some components are exaggerated, omitted or schematically shown.

[0028] In addition, throughout the specification, when it is mentioned that a certain component includes a certain component, as long as there is no particular objection, this does not exclude other components, but means that other components may be included. In addition, throughout the specification, "on - above" means located above or below the object portion, and does not necessarily mean located above the direction of gravity.

Abstract

The present invention relates to a high-air-volume blower fan having non-equally spaced blades, the high-air-volume blower fan forming an air volume by rotating an impeller and a drive motor for driving the impeller, the high-air-volume blower fan comprising: an impeller having formed therein an attachment hole into which the drive motor can be attached; a pair of blades repeatedly arranged at a first interval in the radial direction on each of the upper and lower surfaces of the impeller; the blades include: first blades formed so as to extend in a curvature from the outer peripheral surfaceof the impeller in the inward direction; and second blades which are disposed at a second interval in the clockwise direction or the counterclockwise direction with respect to the first blades, and which extend from the outer side of the impeller to the inner side of the impeller in the radial direction so as to be relatively shorter than the radius length of the first blades. The first intervalsare formed at intervals larger than the second intervals when a plurality of the first intervals are arranged on the impeller in the radial direction.

Description

technical field [0001] The invention relates to a high air volume blower fan with non-equally spaced blades, and relates to a high air volume blower fan with non-equally spaced blades which can improve the air volume by adding an impeller with non-equally spaced blades. Background technique [0002] Drying your hair after shampooing is very important for maintaining a healthy scalp. If wet hair is not left to dry after shampooing, the scalp becomes wet and bacteria can multiply. In addition, the moist scalp environment not only breeds dandruff bacteria, but also various bacteria and other fungi, which can cause unpleasant hair odor. Not only that, it can even induce hair loss. [0003] To prevent this, dry your hair with a hair dryer after shampooing. [0004] On the other hand, a hair dryer is a product that dries wet hair with cold or hot air, and is heated by a main body with a blower fan built in, a handle with a switch, a blower duct guide, and a coil fixed in the bl...
