An example of a conventional technique for solving the problem of such a fan is a multi-directional fan (20-2001-0025369), but only a simple principle is applied, and since a technology applying only one direction curve to the fan is used, The side wind is weak and there are many parts that are not enough for commercialization. In addition, there are a lot of technical deficiencies because of lack of physical studies of wind.

The present invention has been made in order to solve the problems of the related art as described above, and the blade is designed to have a tilt and a curvature so that the air is sucked up and down, and the air discharge is improved to have an excellent wind function, And a wing structure for a slope wind fan to be generated.

According to an aspect of the present invention, there is provided a blade structure for a slope wind fan, comprising: a hub fixed to a rotary shaft of a rotatable fan motor; a through hole formed in the center of the hub; And at least two or more blades are provided so as to generate the fan-shaped wind fan blades.

In addition, the blade side surface may have a curvature such that the blade has a concave shape in a direction in which the blade rotates from the top to the bottom, so that when the blade rotates, air is collected on the upper and lower sides of the blade, Wherein a slope-like fan-shaped blade structure is provided.

In addition, when the length of the upper side is a and the length of the lower side is b, the length of the lower side is made larger than the length of the upper side with respect to the horizontal center portion of the wing surface portion, Or a > b, that is, the length of the upper side is made longer than the length of the lower side, so that more wind is generated in the upper side than in the lower side, thereby providing a blade structure for a slope wind fan .

If the inclination angle of the upper side is Q ₁ and the inclination angle of the lower side is Q ₂ with respect to the horizontal center line and the central axis on the side surface of the wing, Q ₁ <Q ₂ , that is, the inclination angle of the lower side is larger than the inclination angle of the upper side So that more air is generated on the lower side than on the upper side, or Q ₁ <Q _2, that is _, the inclination angle on the upper side is made larger than the inclination angle on the lower side so that more wind is generated on the upper side than on the lower side A blade structure for a slope wind fan is provided.

As described above, the blade structure for a slope wind fan according to the present invention has the following effects.

First, the wind generated by the slope absorbs the upper air and the lower air, so that the wind is generated on the side, which is effective for the air circulation in the room. Therefore,

Second, since one person can use several people together, energy saving is economical,

 Third, since one person can be used by several people together,
