Description

{Fans for a cooling / heating airflow spread}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cooling / heating airflow diffusion fan that functions to diffuse a cooling / heating airflow in a cooling /

A cooling / heating device installed in the ceiling or hung on the ceiling is used for cooling or heating the indoor space. Such a heating and cooling apparatus generally forms a hexahedral body. The air inlet port is formed at the center to suck indoor air while a discharge port is formed at the four sides of the ceiling so that the air sucked into the air inlet port is heat exchanged And then discharges the air through the discharge port. Such a structure can be found in Patent No. 10-0702323 (March 26, 2007) "Ceiling type air conditioner".

However, since the cooling / heating apparatus as described above discharges the cold air or the hot air (hereinafter referred to as 'air conditioner') only in the direction of the discharge port, there is a problem that diffusion of the air conditioner air stream is not smooth. The cooling / heating airflow is discharged only in the direction in which the discharge port faces, so that the cooling / heating airflow is strongly transmitted to the point where the discharge port is directed, while the air conditioning airflow is not properly transmitted or weakly transmitted at the point where the discharge port is not facing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide an apparatus for effectively cooling or heating an entire indoor space by effectively diffusing a cooling / It has its purpose.

The present invention proposes a cooling / heating air flow diffusion fan installed in an air conditioner and capable of uniformly diffusing a cooling / heating air flow discharged through a discharge port into an entire indoor space.

According to the present invention, since the air conditioner can be easily installed in the air conditioner installed in the ceiling, it is possible to uniformly spread the air conditioner air to the whole indoor space while being rotated by the air conditioner discharged from the air conditioner. .

In the present invention, in order to obtain an air conditioner air-conditioner diffusing fan which is installed in an air conditioner and is capable of uniformly spreading the air conditioner air discharged through a discharge port while rotating,

A rotating bundle fixed to an air conditioner installed in a ceiling; and a blade formed radially in the rotating bundle and pivoting around the rotating bundle,

The blades are formed in a plate shape and are inclined so that the front part facing the turning direction on the horizontal plane is closer to the cooling and heating device, and the bent parts are formed on the rear part along the length direction. And proposes a cooling fan diffusing fan that diffuses the cooling airflow while circulating the bundle as an axis.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

As shown in the drawing, the diffusion fan 100 according to the present invention includes a rotating bundle 120 fixed to a ceiling heating / cooling apparatus 200, and a plurality of bundles 120, which are formed radially in the rotating bundle 120, And a wing 160 for pivoting the rotation bundle 120 in accordance with the rotation of the rotating bundle 120.

As shown in FIG. 9, the cooling / heating device 200 has a generally rectangular shape. Four air outlets 240 are formed at the edge of the air inlet 220 to discharge the air conditioner airflow through the air outlet 240. This is not different from the known configuration.

The rotating bundle 120 is fixed to a cover covering the inlet port 220. And is firmly and detachably fixed to the cover through a separate fixing device so that it can be installed and removed as needed. According to the detachable fixing structure, the diffusion fan 100 can be installed not only in the newly installed cooling / heating apparatus 200 but also in the conventional cooling / heating apparatus 200 installed on the ceiling.

The rotation bundle 120 is rotatable and can be rotated while being fixed to the intake port 220 cover. The blades 160 can be pivoted about the rotation bundles 120 by rotating the wings 160 while the wings 160 are installed.

The vanes 160 are formed in the form of a thin plate made of metal or synthetic resin and have a predetermined length and width. Considering the weight, it is formed mainly of synthetic resin. When the shape of the plane is viewed, the portion facing the rotation bundle 120 is narrow in width, is directed toward the opposite side, is wide, . However, the present invention is not limited to these materials and shapes.

As shown in FIG. 7, the vane 160 is slanted to a certain degree so that the front portion of the vane 160 facing the turning direction on the horizontal plane becomes closer to the air conditioner. And is installed in the rotary unit 120 such that the rotary unit 120 is inclined at a predetermined angle alpha on the horizontal plane as the wings of the fan. As described later, when the wing 160 is fixed to the support bar 140, the angle is adjusted when the support bar 140 is fixed to the rotation bar 120. According to this configuration, the vanes 160 can be swung by the cooling / heating air flow discharged from the discharge port 240 with the rotary vane 120 as an axis, so that the air conditioning airflow is naturally spread while turning.

A bent portion 166 is formed at a rear portion of the blade 160 with respect to a direction in which the blade 160 rotates. The bent portion 166 is formed on the whole or in part along the longitudinal direction of the blade 160. The bent portion 166 is formed in a concave portion 162 or an upper surface which is convexly protruded from the bottom surface of the blade 160, And may be formed as convex portions 164 which are convexly formed. In order to effectively diffuse the cooling / heating airflow, it is preferable that the concave portion 162 and the convex portion 164 are alternately formed into a wave shape.

The concave portion 162 or the convex portion 164 as described above diffuses the air conditioning airflow farther and to a wider range. This is achieved by causing a pressure difference between the upper and lower surfaces of the vane 160 through the concave or convexly formed surface and by varying the angle of the surface pushing the air conditioner air flow so that the angle for diffusing the air conditioner air flow is further widened.

The concave portion 162 is formed at a point approximately 1/3 of the width of the vanes 160. The width of the concave portion 162 increases toward the rear end in the width direction and the depth becomes deeper. With this configuration, it is possible to minimize resistance caused by the cooling / heating airflow in the course of the rotation of the vanes 160 and to smoothly induce and diffuse the cooling / heating airflow. Likewise, the convex portion 164 is formed to have a wider width and a higher protruding height from the front end to the rear end, so that the air conditioner airflow can be effectively diffused. As a result, Is formed in an inverted shape.

As shown in FIG. 5, the bent portion 166 may be formed only on a part of the blade 160.

The blade 160 may be bent toward the cooling / heating device 200 to form a resistance surface 168. The resistance surface 168 is inclined toward the end of the blade 160 from the front to the rear with respect to the direction in which the blade 160 is rotated. 2 to 4, and the surface itself is formed to be distant from the rotation bundle 120 toward the rear of the wing 160. As a result, when the cooling / heating air discharged from the cooling / heating device 200 touches the resistance surface 168, the wing 160 pushes the wing 160 along the inclined surface, thus helping the wing 160 to be pivoted So that the turning speed of the blade 160 can be improved.

1 and 6, the wings 160 may be installed in the rotary assembly 120 by the support rods 140. In the rotary assembly 120, Thereby fixing the blade 160 to the support rod 140 through a screw or the like.

The support rods 140 are formed to have a predetermined length and are fixed by being coupled to the rotation bundle 120 at one end. The plurality of support rods 140 are radially formed by being removably fixed to the rotation bundle 120 at regular intervals. The support rods 140 may be fixed by fixing the support rods 140 to one end of the rotation rods 120 so that one end of the support rods 140 may be fixed to the coupling grooves.

The vanes 160 are installed at the support rods 140 at a certain distance from the rotation vortex 120. At the same time, the support rod 140 is fixed to the support rod 140 with the end of the support rod 140 reaching the center of the blade 160. The support rods 140 are fixed on the upper surface of the vanes 160 so as not to interfere with the flow of the cooling / heating airflow diffused by the bottom surface of the vanes 160. [

As shown in FIG. 9, the blade 160 fixed to the support rod 140 is installed such that its end portion is located below the discharge port 240. In this configuration, the cooling / discharging air discharged from the discharge port 240 is prevented from being interrupted by the support rod 140, which helps the blades 160 to smoothly turn. Meanwhile, the length of the support bar 140 is calculated in advance so that the position of the vane 160 is as described above, and is formed as described above.

In the structure in which the wing 160 is fixed to the support rod 140, the end of the wing 160 is bent backward by the cooling / have. This is a phenomenon in which the blade 160 is deepened when it is formed of a thin synthetic resin plate.

8, a strap 180 having one end fixed to the support rod 140 is provided and the other end is fixed to the end of the vane 160, so that the vane 160 is rotated by a cooling / 160 are supported so as not to be broken. One end of the string 180 is fixed to the support bar 140 located on the upper surface of the vane 160 and the other end is provided with a protrusion at the end of the vane 160. The string 180 thus installed supports the end of the vane 160 so as not to be broken even when subjected to a strong force by a cooling / heating air stream discharged from the discharge port 240.

Hereinafter, the process and operation of installing the diffusion fan 100 according to the present invention will be described.

First, a diffusion fan 100 as shown in FIG. 1 is prepared. The wings 160 are fixed to the support rods 140 so that the support rods 140 are inserted into the coupling grooves formed in the rotation rods 120. [ The installation of the vanes 160 in the rotary assembly 120 is completed.

When the cooling / heating apparatus 200 to be installed with the diffusion fan 100 is determined, the diffusion bundle 120 is fixed to the inlet port 220 of the cooling / heating device 200 by the diffusion fan 100. When the cover is detached from the inlet port 220, the rotating bundle 120 is fixed and then the cover is fixed to the inlet port 220. Thus, the installation of the diffusion fan 100 is completed. Of course, it is also possible to fix the rotatable bundle 120 in advance on the cover of the intake port 220 according to need, and to assemble the support rod 140 to which the blade 160 is fixed later.

As shown in FIG. 9, the diffusion fan 100 is installed in the cooling / heating device 200 through the above process. In this state, when the cooling / heating airflow is discharged from the discharge port 240, the rotating body 120 is rotated by the cooling / heating air flow through which the wing 160 is discharged. The swirling vane 160 spreads the air-conditioning airflow evenly in the indoor space. In particular, the air conditioning airflow is spread farther and wider by the bent portion 166.

Meanwhile, when the diffusion fan 100 is installed in the cooling / heating device 200 as described above, even if the cooling / heating condition is set to a difference of 1 to 3 degrees Celsius at a desired temperature under the same condition, . As a result, the desired cooling effect can be achieved even if the set temperature is higher in the cooling apparatus, and the desired heating effect can be realized even if the set temperature is lowered in the heating apparatus. Therefore, it is possible to reduce the electricity consumption by 10 ~ 20% as a whole.
