Description

Fan {A FAN}

The present invention relates to an electric fan, and more particularly, to a fan capable of rotating a fan body by 360 ° by providing a wing-shaped rotary shaft around a central fan, and being able to use the fan body in various positions.

Conventional fans typically include a set of vanes or vanes mounted to rotate about an axis, and a drive for rotating the set of vanes to create an air flow. "Wind chill" or breeze is generated by the movement and circulation of the air flow, which results in the user experiencing the cooling effect as heat is dissipated through convection and evaporation. These fans are available in various sizes and shapes. For example, there are a ceiling fan, a desk fan, a stand fan, and the like.

However, the fan according to the conventional structure having such a structure has the following disadvantages. In other words, as described above, except for the fan installed in the ceiling, the fan has a base having an extended portion that supports the entire body with respect to the bottom surface, a motor assembly provided at the upper end of the base, And a fan assembly for generating wind. Such a fan blows wind toward various points in accordance with the rotation of the motor assembly and the fan assembly.

However, in the conventional fan, the rotation angle of the motor assembly and the fan assembly is limited due to the physical structure. That is, when the motor assembly section or the fan assembly section is rotated in the up / down / left / right direction, it is impossible to rotate the motor assembly section or the fan assembly section beyond a certain angle.

In addition, a conventional electric fan normally operates only when the base is kept in contact with the floor surface. This is because only one base is responsible for the function of the support surface for supporting the fan. This may also be the reason for limiting the angle of rotation of the fan.

Accordingly, the present invention provides an electric fan having improved structure so that an angle adjustment in the up / down / left / right direction and a 360 degree rotation are possible and the installation posture can be changed variously.

In addition, the present invention aims at suppressing the generation of noise in the left / right direction as much as possible due to the improvement of the structure of the fan.

In addition, the present invention aims at selectively using solar heat as an energy source due to the structural change of the fan.

In order to achieve the above object, according to a feature of the present invention, there is provided a refrigerator comprising: a main body including a blowing fan and a motor; A pair of wings corresponding to both sides of the main body; And a support for connecting the wings to each other, wherein the wings are polygons of a plate shape having a plurality of sides, and the sides of the wings are formed to have the same length and the same inclination or different from each other.

The main body and the wing portion can be engaged and disengaged, and the main body is configured to rotate between the wing portions.

The wing portion may further include a noise prevention pad.

The wing portion may be formed of a solar heat collecting plate.

According to the fan of the present invention as described above, the present invention has changed the overall structure so that a pair of blades are mounted on the left and right sides of the main body and the main body of the fan. The wing portion is formed of a polygonal plate having a plurality of surfaces. At this time, each surface is formed with the same length and different inclination or different from each other. Therefore, the present invention can be used while positioning the fan in various positions by using each side of the wing portion.

In addition, the wing portion can be mounted with a size enough to cover the main body when seen from the side, and the noise prevention pad can be mounted according to circumstances, thereby preventing the motor noise generated at the time of driving the fan from being transmitted to the outside .

Furthermore, when the wing portion is formed of a solar heat collecting plate, there is an advantage that it can be easily used even in a place where a commercial power source is difficult to use.

The design of the present invention is to improve the basic shape of the fan, thereby improving the customer satisfaction due to the new design, as well as providing the technical features that enable to overcome the limit of the angle adjustment, reduce the noise and use alternative energy.

And a preferred embodiment of a fan of the present invention for providing such a technical feature will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an electric fan proposed by the present invention, and FIG. 2 is an exploded perspective view. The fan 100 includes a cylindrical housing 112 and a main body 110 including a protection net 114 installed on the front and rear sides of the housing 112. Inside the main body 110, a blowing fan for generating wind and a motor for rotating the blowing fan are constituted. That is, the present invention is a structure in which not only a blowing fan but also a motor are constituted together in the main body 110.

An operation panel (not shown) for operating the fan 100 is provided on the outer circumferential surface of the housing 112. At this time, the operation panel can be constituted by a physical input button or a touch input method capable of selectively inputting information.

On the outer circumferential surface of the housing 112, a pair of coupling grooves 116 are formed at symmetrical positions. The coupling groove 116 is a portion to which a coupling protrusion 122 of the wing portion 120 or 120 'described below is coupled. The rotation angle of the main body 110 is 90 degrees, The coupling grooves 115 and the coupling protrusions 122 are connected to the main body 110 or the wing portions 120 (i.e., the main body 110 or the wing portion 120) 120 'are rotated. At this time, it is also possible to provide angle adjusting means in addition to the structure of simple rotation so that the wings 120 and 120' can be rotated only by predetermined angles.

The wings 120 and 120 'may be formed to have a size capable of completely covering the main body 110 when viewed from the side in a state of being engaged with the main body 110. According to the embodiment, the wings 120 and 120' are composed of a hexagonal flat plate . In this way, when the main body 110 is covered, it is possible to prevent noise generated when the fan 100 is driven from the side to some extent, so that the noise-blocking effect can be expected. The wings 120 and 120 'may serve as a base on which the fan 100 can be installed. In addition, the wings 120 and 120 'are formed in a polygonal shape with six sides (a to f, a' to f '). When each of the sides (a to f, a 'to f') is brought into contact with the bottom surface, the fan can be adjusted to be controlled at six angles. The description of these examples will be described below together with the drawings.

Meanwhile, although the wings 120 and 120 'have a flat plate shape in the present invention, the wings 120 and 120' may have various structures. For example, as described above, since the noise blocking prevention function is performed, the noise preventing pads (not shown) may be mounted on the wing portions 120 and 120 '. In addition, as shown in the drawing, the wings 120 and 120 'include six panels (i.e., unit panels having sides), and each of these panels may be formed of a solar collector plate. Of course, even if the wings 120 and 120 'are constituted by a single panel, it is natural that all of them can be replaced with solar collectors. In doing so, there is an advantage that it can be used in an outdoor environment where it is difficult to use a commercial power source. Of course, in order to use the solar heat, it is natural that a charging and supplying circuit for charging and supplying solar heat to the fan 100 is provided.

A support 130 for connecting the pair of wing parts 120 and 120 'to each other is formed. The support base 130 has a structure in which both ends of the support base 130 are engaged with or separated from one side of the wing portions 120 and 120 '. In the drawings of the embodiment, it is apparent that the support member 130 has a structure that can be coupled to only one side, but it is natural that any other five sides can be combined and separated at any time. The support base 130 also serves to support the fan 100 in cooperation with the wing members 120 and 120 'when the fan 100 is used. That is, the support base 130 supports both ends And supports the fan 100 together with the surfaces of the wings 120 and 120 'that are coupled to the fan 100'.

Next, a use example of the fan 100 having such a configuration will be described.

As shown in the perspective view of FIG. 1, the fan 100 can be used in a standing state using a pair of wings 120, 120 'and a support 130. In this state, the main body 110 can be rotated by 360 ° using the hexagonal plane due to the coupling structure with the wing portions 120 and 120 ', so that the angle is not limited.

3, the fan 100 can be used in various positions (i.e., angles) by using the sides of the wings 120 and 120 ', as shown in FIG. 3, in addition to the basic posture of FIG. You can. That is, when any side forming the pair of wings 120 and 120 'is brought into contact with the floor, the angle of the fan can be adjusted because the fan itself is inclined by the inclination of the side. Therefore, since the wing portions 120 and 120 'are hexagonal and six sides are provided in the embodiment, the angle can be adjusted six times using each side. However, it is a matter of course that the angles can be more variously adjusted if the slopes (slopes) and the lengths of the sides of the wings 120 and 120 'are made different from each other.

3, the main body 110 located between the wing portions 120 and 120 'can be rotated 360 degrees in a state where the posture of the fan 100 is maintained, It will be possible.

When the fan 100 is used as described above, the wings 120 and 120 'provided on both sides of the main body 110 can block the noise of the fan motor and the blowing fan generated in the main body 110. Particularly, if the noise preventing pads are installed in the wings 120 and 120 ', the noise blocking effect can be doubled.

Fig. 4 is a diagram showing another use example of the present invention. In the above-described embodiment, the posture of the fan 100 is set up on one side of one of the wings 120 or 120 '. When the outer surface of one of the wings 120 or 120 'is brought into contact with the bottom surface of the wings 120 and 120', the fan 100 will be in a raised state. In addition to using the sides of the wings 120 and 120 ' (100) can be used safely.

As described above, according to the present embodiment, the fan 100 can be used in various postures and various angles, and noise generated when the fan 100 is driven can be prevented.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It will be apparent that modifications, variations and equivalents of other embodiments are possible. Accordingly, the true scope of protection of the present invention should be determined by the technical idea of the appended claims.
