Detailed descriptions of well-known functions and configurations that are judged to unnecessarily obscure the gist of the present invention are omitted.

Figure 1 shows a ventilation fan for a non-powered air conditioning diffuser equipped with a vortex fan according to an embodiment of the present invention. , FIG. 2 is an separated perspective view of a ventilation fan for a non-powered air conditioning diffuser equipped with the vortex fan shown in FIG. 1, and FIG. 3 is a cross-sectional view A-A of the ventilation fan for a non-powered air conditioning diffuser equipped with the vortex fan shown in FIG. 1. , FIG. 4 shows the use state diagram of the non-powered air conditioning diffuse ventilation fan equipped with the vortex fan shown in FIG. 1.

As shown in the drawing, the ventilation fan 100 for a non-powered air conditioning diffuser equipped with a vortex fan according to an embodiment of the present invention includes a housing 10, a rotation shaft 20, a vortex fan 30, and a rotating fan. It includes a suction fan (40) and rotation strengthening means (50).

As shown in Figures 1 to 3, the housing 10 has a space inside, and an inlet 11 through which air flows is formed at the upper part, and an outlet 12 through which the introduced air is discharged at the lower part. to form.

Here, the housing 10 protects the rotating shaft 20, the vortex fan 30, the rotating suction fan 40, and the rotation strengthening means 50 to be installed later, and at the same time sucks in the surrounding air. It is used as a medium for discharge to the outside.

As shown in Figures 2 and 3, the rotation axis 20 is formed vertically and elongated at the center of the housing 10 and is fixed to the housing 10 so as to be rotatable relative to the housing 10. .

Here, the rotation shaft 20 serves as a medium to rotate the vortex fan 30 together based on the rotation power of the rotation suction fan 40.

The rotation shaft 20 may be connected and fixed to the housing 10 based on a normal bearing so that it can rotate relative to the housing 10.

As shown in Figures 1 to 3, the vortex fan 30 is installed on the upper part of the rotation shaft 20 so as to be located at the inlet 11 of the housing 10 and rotates together with the rotation shaft 20. This induces a vortex of air around the inlet 11 of the housing 10, and a communication path 61 communicating with the inlet 11 is formed inside.

That is, as shown in FIG. 4B, the vortex fan 30 rotates with the rotation shaft 20 and induces a vortex of air around the inlet 11 of the housing 10, thereby causing the rotation suction fan 40. The suction force causes a lot of air around the inlet to be collected and sucked in.

Therefore, the ventilation effect of the room where the ventilation fan 100 for a non-powered air conditioning diffuser equipped with the vortex fan of the present invention is installed is maximized, leading to an effective and comfortable indoor environment.

As shown in Figures 2 and 3, the rotating suction fan 40 is installed at the lower part of the rotating shaft 20 so as to be located at the outlet 12 of the housing 10, and is used as an external air conditioning unit. Based on the suction power of the large blowing fan, the air around the inlet 11 is forced to be sucked in while rotating with the rotating shaft 20.

Typically, ventilation fans are installed indoors in factories, homes, and restaurants where pollutants are generated, and the air sucked in with pollutants through the ventilation fan has the suction power of a large air conditioning blower fan (not shown) installed outside. All are transported through the tablets and discharged.

Here, as shown in Figure 4b, the ventilation fan 100 for a non-powered air conditioning diffuser equipped with the vortex fan of the present invention uses the suction power of the large blowing fan to rotate the rotation shaft 20. The rotating suction fan 40 is placed on the rotating shaft 20 near the outlet 12 of the housing 10, which is located closest to the rotating suction fan 40 based on the suction power of the large blowing fan. As this is easily rotated, the rotation shaft 20 is rotated together.

Therefore, when the rotary suction fan 40 rotates based on the suction force of the large blowing fan, the vortex fan 30 rotates together with the rotation shaft 20 to create a vortex of air around the inlet 11 of the housing 10. At this time, a large amount of air surrounding the inlet 11 of the housing 10 is sucked and collected through the unique suction force of the rotary suction fan 40 generated as the rotary suction fan 40 rotates, making the indoor environment easier. Ensure that a pleasant environment is created.

In addition, due to the nature of the rotating suction fan 40 using the suction force of an external large blowing fan, the use of a separate motor is not required for the ventilation fan itself, thereby preventing noise caused by the use of the motor and operating the motor. Cause: Electrical safety accidents due to the use of electricity can be prevented in advance, leading to comfortable and safe use of ventilation fans.

In addition, the air flowing into the inlet 11 of the housing 10 through the rotating suction fan 40 naturally passes through the rotating suction fan 40 in the process of being discharged through the outlet 12, At this time, using the air passing through the rotary suction fan 40, the rotation strengthening means 50 induces more efficient rotation of the rotary suction fan 40. This is explained in the rotation strengthening means below ( 50) will be explained in detail.

As shown in Figures 2 and 3, the rotation strengthening means 50 allows the rotary suction fan 40 to be easily rotated based on the wind pressure of the air flowing into the inlet 11 of the housing 10. By encouraging you to do so,

It is located close to the lower part of the inlet 11 of the housing 10 so that the passage of the inlet 11 narrows, but as it extends outward from the center, a gentle downward slope is formed so that the air flowing in through the inlet 11 An annular guide plate 51 that guides air to descend along the inner wall of the housing 10 while minimizing friction with the housing, and a plurality of equiangular spiral steps 52a are formed on the upper surface of the guide plate 51. The air guided through the guide plate 51 rotates like a whirlwind, and the step 52a is a rotating piece 52 that guides the air to rotate in the same direction as the rotating direction of the rotating suction fan 40. And, the lower inner wall of the housing 10 is formed to be inclined downward to guide the air descending through the housing 10 to the edge of the rotary suction fan 40, thereby causing the rotary suction fan 40 to rotate at high speed. It is configured to include a guiding inclined surface 53.

Here, if the air flowing into the inlet 11 of the housing 10 due to the suction force of the rotating suction fan 40 flows directly through the wide inlet 11, it is difficult to secure a high wind speed of the air. And, if such air is supplied downward to the entire blade of the rotary suction fan 40 at the bottom, efficient rotation of the rotary suction fan 40 can be induced through the air passing through the rotary suction fan 40. There will be no more.

Therefore, as shown in Figure 4c, the guide plate 51 of the rotation strengthening means 50 is located near the inlet 11 of the housing 10 to narrow the passage of the inlet 11 through which air flows. The wind speed of the air passing through the inlet 11 is induced to naturally increase, and the air with the increased wind speed is guided outward along the slope of the upper surface of the guide plate 51 to descend along the inner wall of the housing 10. .

At this time, the upper surface of the guide plate 51 is formed with a gentle downward slope outward from the center, so that the load from the high-speed air guided along the guide plate 51 is minimized, so that the air maintains a high speed and moves into the housing. Be guided to the inner wall of (10).

At the same time, the wind guided along the guide plate 51 is induced to rotate like a whirlwind due to the rotating piece 52 formed on the upper surface of the guide plate 51, so that the wind descending along the inner wall of the housing 10 Allow it to rotate and descend naturally.

Here, the rotating piece 52 guides the air to rotate in the same direction as the rotating direction of the rotating suction fan 40.

Then, the air with a high wind speed rotating like a whirlwind along the inner wall of the housing 10 is guided and concentrated toward the edge of the rotary suction fan 40 through the guiding inclined surface 53, that is, large wings are formed. It is guided and concentrated at the edge of the rotary suction fan 40 to induce very efficient high-speed rotation of the rotary suction fan 40.

At the same time, the swirling air helps the rotary suction fan 40 to rotate at high speed, and of course, induces a more stable high-speed rotation of the rotary suction fan 40.

That is, the rotation strengthening means 50 induces stable high-speed rotation of the rotary suction fan 40, thereby providing excellent ventilation function and the rotary suction of the non-powered air conditioning diffuse ventilation fan 100 equipped with the vortex fan of the present invention. Non-powered high-speed rotation of the fan 40 is ensured.

Here, the guide plate 51 is implemented to be coupled and fixed to the housing 10, but of course, it can also be implemented to be connected and fixed to the rotation axis 20 and rotate together with the rotation axis 20.

Meanwhile, as shown in FIGS. 1 to 3, it further includes an air volume control means 60 for controlling the flow rate of air flowing into the inlet 11 of the housing 10,

The air volume control means 60 is formed inside the vortex fan 30 to communicate with the inlet 11 of the housing 10, and includes a communication path ( 61), and a fixed plate formed inside the communication passage 61 to close the communication passage 61, and having one or more basic discharge holes 62a formed at the edge to communicate with the communication passage 61. A sieve (62), at least one selection discharge hole (63) formed on the stationary plate body (62) and in communication with the communication path (61), and the stationary plate body rotatable with respect to the stationary plate body (62). It is stacked and fixed on the upper part of (62), and one or more control holes (64a) are formed inside it and communicate with the selection discharge hole (63), so that the selection hole (63) rotates with respect to the fixing plate body (62). It is configured to include a selection plate body 64 that freely adjusts the size of the selection discharge hole 63 exposed to the outside by closing or adjusting the degree of communication between the selection discharge hole 63 and the control hole 64a. It is characterized by

Here, the air volume control means 60 is connected to the communication path 61 and the housing through the basic discharge hole 62a due to the nature of the basic discharge hole 62a of the fixed plate body 62 being always exposed and open. The basic volume of air flowing into the inlet 11 of 10) is ensured.

That is, if a larger air flow rate (air volume) is required than the basic air volume secured through the basic discharge hole 62a of the air volume control means 60, the selection plate 64 as shown in FIG. 4A By rotating the control hole 64a formed in the selection plate body 64 and the selection discharge hole 63 of the fixing plate body 62, the selection discharge hole 63 is exposed to the outside. At this time, the required discharge hole 63 is exposed to the outside. The size of the selected discharge hole 63 exposed to the outside is appropriately adjusted in consideration of the amount of air flowing.

Then, the air volume control means 60 allows a larger amount of air to flow into the communication passage 61 and the housing 10 through the basic discharge hole 62a and the selective discharge hole 63 that is selectively exposed to the outside. It allows distribution through the inlet (11).

Meanwhile, as shown in FIGS. 2 and 3, there is a rotor on the rotation shaft 20 that rotates together with the rotation shaft 20 and applies centrifugal force to the rotation shaft 20 to induce smooth rotation of the rotation shaft 20. It further includes (70);

The rotor 70 is formed on the rotation shaft 20 and rotates together with the rotation shaft 20, and a plurality of transfer paths 71a having an upward slope as they extend outward from the center are formed at equal intervals inside the rotor 70. , an annular rotating body 71 having a resting groove 71b formed at one end of the conveying passage 71a located at the center, and disposed on the conveying passage 71a of the rotating body 20, At the point when the rotation of the entire body 71 begins, it is placed in the resting groove 71b at one end of the transfer path 71a, and when the rotating body 71 is rotated, it is positioned at the other end of the transfer path 71a by centrifugal force. A rotating ball 72 is formed on the rotating body 71 to be long in the longitudinal direction of the conveying path 71a to prevent the rotating ball 72 located in the conveying path 71a from leaving the outside. At the same time, it is configured to include a guide guide 73 that guides the transfer of the rotating ball 72 transported along the transfer path 71a.

Here, before the rotation of the rotation shaft 20 begins, the rotation ball 72 of the rotor 70 is seated in the seating groove 71b due to the inclination of the transfer path 71a and moves the rotor (71a). The center of gravity of the rotor 70 is located inside (the center) of the rotor 70. This is because at the point when the rotation of the rotor 70 begins with the rotation axis 20, the rotor 70 ) If the center of gravity is formed outside, a rather high load is formed on the initial rotation of the rotor 70 along with the rotation axis 20, which may interfere with the rotation of the rotation axis 20. At the time of initial rotation, the rotating ball 72 is designed as described above so that it can be located inside the rotor 70.

That is, as shown in FIG. 4D, when the rotor 70 is first rotated together with the rotation axis 20, the rotation ball 72 is located inside and moves the rotor together with the rotation axis 20. 70) is induced to easily rotate, and then, when the rotation shaft 20 and the rotor 70 rotate at high speed, the centrifugal force of the rotor 70 naturally increases, and the centrifugal force causes the rotating ball ( 72) leaves the resting groove 71b of the rotating body 71 and is transported outward along the slope of the transfer path 71a.

Here, the inclination of the transfer path 71a is preferably formed to be very small so that the rotating ball 72 can be easily transported along the inclination of the transfer path 71a.

Then, as the center of gravity of the rotor 70 moves from the inside to the outside, the centrifugal force of the rotor 70 increases, and based on the increased centrifugal force of the rotor 70, the rotation shaft 20 Ensure stable, high-speed rotation.

If the operation of the ventilation fan 100 for a non-powered air conditioning diffuser equipped with the vortex fan of the present invention is stopped and the rotation of the rotor 70 along with the rotation shaft 20 stops, the rotor 70 As the centrifugal force is released, the rotating ball 72 is transported inward along the slope of the conveying path 72a and is seated in the resting groove 71b of the conveying path 71a, and the rotation of the rotating shaft 20 begins. It returns to its original state before it was finished.

The ventilation fan 100 for a non-powered air conditioning diffuser equipped with a vortex fan according to an embodiment of the present invention having the above configuration is used as follows.

First, the ventilation fan 100 for a non-powered air conditioning diffuser equipped with the vortex fan of the present invention is installed indoors in factories, homes, restaurants, etc. where ventilation is required, and then installed outside (a large blowing fan for air conditioning and normal piping) to be connected to each other through .

Then, as shown in Figure 4a, the user appropriately adjusts the flow rate of air sucked and distributed through the non-powered air conditioning diffuse ventilation fan 100 equipped with the vortex fan of the present invention through the air volume control means 60. , Of course, the settings are adjusted appropriately considering the environment or conditions in which the product is used.

Then, as shown in Figure 4b, when the vortex fan 20 rotates together with the rotating suction fan 40 due to the suction force of the large blowing fan, the vortex fan 20 moves around the inlet 11 of the housing 10. A vortex is formed so that a lot of air can be collected, and at this time, a lot of air around the inlet 11 is sucked in using the suction force of the rotating suction fan 40, thereby creating a comfortable indoor environment.

At this time, as shown in FIGS. 4C and 4D, the rotating suction fan 40 induces stable high-speed rotation through the rotation strengthening means 50 and the rotor 70.

The ventilation fan 100 for a non-powered air conditioning diffuser equipped with the vortex fan of the present invention consisting of the above components is a rotating suction fan ( 40) is rotated, and the suction power of the large blowing fan is effectively used through the rotation strengthening means 50 to secure a stable rotational force of the rotary suction fan 40, so that a separate device is used to rotate the rotary suction fan 40. Since the use of a motor is not required, the problems of noise generation due to the use of a motor in a conventional ventilation fan, inconvenience in building and operating and managing power equipment, and electrical safety accidents caused by power equipment are resolved, providing excellent use safety of the product. It has the effect of ensuring convenience of installation and operation and management.

In addition, since the rotating suction fan 40 is rotated together with the vortex fan 30 connected to the rotating shaft 20, air can be sucked in while forming a vortex around the inlet 11 of the housing 10. Not only can a lot of air be sucked in efficiently, but also the amount of air sucked in can be appropriately adjusted through the air volume control means 60, which has the effect of securing excellent versatility of the product.
