Description

air blower

The present invention relates to a blower, and more particularly, by drawing a rear airflow of the air passage formed in the center by the pressure difference generated in the blowing space and the discharge port formed between the axial rotary blades to increase the air flow rate and wind speed at the same time produced It is related to a blower to minimize the cost.

In general, home or business blowers (fans) are available in a variety of sizes and shapes, there are also upright, wall or ceiling type to be used on the floor, axial blades or centrifugal mounted to rotate on a generally rotating axis And a drive device for generating an air flow through the vanes. The blower is intended for purifying cold, warm, or natural air at a specific location or for delivery to the body to provide a cooling or warming effect.

In addition, the blower has the disadvantage of adopting a relatively high output motor because it is determined by the amount of wind discharge and the wind intensity in proportion to the rotor blade size and the number of revolutions. However, while the noise is low, the centrifugal type is a forced discharge type in which strong wind is discharged by lowering the pressure during air discharge, but there is a lot of air discharge, but there is a serious noise problem.

For example, the axial flow type of Korean Patent Registration No. 10-1279023 (2013.07.02. Announcement) "Axial flow blower using a diffused diffuser" and Patent Publication No. 10-2014-0126501 (Published October 31, 2014) "vehicle air conditioner Blowers "have been proposed, and they achieve the purpose of smoothing the inflow of air and preventing rotational airflow, but are unable to increase the air volume and wind speed.

In addition, Korean Patent No. 10-1167907 (announced on July 30, 2012) "Fan" and Patent No. 10-1472759 (announced on December 15, 2014) "Wingless Fan" have been proposed as a centrifugal type. 10-1293593 (August 13, 2013.) "Fan" has been proposed. They can increase the amount of air and wind speed by using the air pressure difference of the discharge space. However, the air flow is inefficient due to the wind pressure loss. There is a disadvantage.

Accordingly, the present invention is simple and reasonable in structure and, due to the deficiencies and shortcomings of the prior art, generates a pressure difference through an improved structure in the center of the blower space and the outlet and the air passage leading from between the axial rotor blades. The purpose of the present invention is to provide a blower that draws rear airflow to increase air volume and wind speed while minimizing noise.

The blower of the present invention includes a cylindrical outer casing forming a blowing space between the air inlet and the discharge port, and a rotary blade mounted to the blower space, and a drive unit installed inside or outside the outer casing to drive the rotary blade. In the blower comprising: a center tube disposed inside the inlet side of the outer casing and formed with an induction air passage in the center and perforated a plurality of through-holes on the circumferential surface of the inlet air to enter the blowing space; ; A bearing supporting and coupling the inner diameter to the circumferential surface of the center tube so as to rotate and rotate the rotary ring equipped with the rotary blades; A relatively high pressure air flows into the air passage of the center tube through the phenomenon that the air flows from the tip circumferential surface of the center tube toward the discharge port formed at the outer casing end and the air flows out to the discharge port so that the moving speed increases and the air pressure decreases. An outer casing formed to increase the amount of exhaust air by moving together; Technical support can be characterized in that one end is fixed to the center tube to support the center tube and the center tube and the other end is made of a plurality of supports that are fixed to the inside of the outer casing.

In addition, the present invention may be characterized in that the driving portion for rotating the rotary blade made of a power source of the internal motor or an external drive motor mounted around the inner center tube.

The blower of the present invention comprises a drive structure and a support structure of a rotary blade and a blower space, which are composed of a power source of an internal motor which prevents resistance from flowing in the air blown from the axial rotary blade and the rear air moved by the pressure difference. The structure of the combination of the center and the center pipe is simple and reasonable, and the air flow space and the discharge port and the air passage are formed in the center between the axial rotor blades to create a pressure difference and attract the rear airflow It has the effect of increasing the wind speed and minimizing the noise at the same time.

Hereinafter, the configuration and operation of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, the term or word used in the present specification and claims is based on the principle that the inventor can appropriately define the concept of the term in order to best describe the invention of his or her own. It should be interpreted as meanings and concepts corresponding to the technical idea of

As shown in FIG. 1, when the rotor blade 2 rotates, the air moves. At this time, the air moves directly to the blowing space 13, but naturally the air moves to the induction air passage 51.

FIG. 2 is a through-hole 61 formed to allow air to flow into the blowing space 13 in the induction air passage 51 in FIG. When the rotary blade 2 rotates, the air moving speed of the blowing space 13 is relatively faster than the induction air passage 51. The physical phenomenon that occurs at this time is the air pressure of the blowing space 13 is relatively lower than the air pressure of the induction air passage (51). Therefore, the air of the induction air passage 51 having a high air pressure flows to the blowing space 13 through the through hole 61. This physical phenomenon is well known and will not be described separately.

Figure 3 shows an example of a blower having a stand according to the present invention.

As shown in the present invention, as shown in Figs. 4 and 6, the cylindrical outer casing 1, which forms a blowing space 13 between the air inlet 11 and the outlet 12, and the blowing of the outer casing 1 The basic configuration of the axial blower including the rotary blade 2 mounted in the space 13 and the drive unit for driving the rotary blade 2 is used.

In order to solve this problem, the rotor blade 2 is fixed to the ring-shaped rotary ring 42 without being fixed to the rod-shaped shaft. Mounted on the circumferential surface of the bearing 43 so as to rotate the rotary ring 42 holding the rotary blade 2, it is disposed inside the inlet 11 side of the outer casing (1) and the air reservoir in the center The center tube 5 in which the furnace 51 is formed is provided, and the said bearing 43 is attached to the circumferential surface of this center tube 5, and is comprised.

In addition, the air inlet 11 is formed larger than the width of the rotary blade (2) mounted on the circumferential surface of the center tube (5), and is introduced into the air inlet (11) through the rotation of the rotary blade (2) The air can be quickly discharged to the discharge port 12 on the opposite side of the outer casing (1) while minimizing the impact or resistance generated, the air passage 51 of the central portion leading from the center tube (5) Since the air pressure is high, the air volume and the wind speed are increased by drawing together the high air pressure of the air passage 51 by the air discharged to the discharge port 12 at a low speed and the low air pressure.

The outer casing 1 extends horizontally from the tip circumferential surface of the center tube 5 toward the discharge port 12 formed at the tip of the outer casing 1 or increases the speed of the discharged air and lowers the air pressure. Blowing space 13 is formed toward the discharge port 12 so that the air flows smoothly so that the space is narrow, it is made in a funnel shape as shown in FIG.

On the other hand, it is not limited to forming the outer casing (1) in a funnel shape to narrow the space while extending the blowing space 13 between the outer casing (1) and the center tube (5) toward the discharge port (12). On the contrary, the center tube 5 has a reverse funnel shape, and the outlet 12 of the outer casing 1 can be narrowly formed to be coupled to the tip of the center tube 5.

And one end is fixed to the center tube (5) to support the center tube (5) and the other end is fixed to the inside of the outer casing (1) of 3 to 4 strips or rod-shaped to minimize the flow resistance of air A support 7 is provided.

On the other hand, the drive unit for rotating the rotary blade (2) of any of the inner tube 4 and the external power source (4 ') mounted to the outside of the inner motor (4) or the outer casing (1) mounted on the bearing (43). When operating the rotary blade 2 by using one is configured to allow the air flowing into the inlet 11 of the outer casing (1) and the air passage 51 of the center tube (5) flows smoothly without resistance. .

The inner motor 4 for rotating the rotary blade 2 is mounted on the circumferential surface of the center tube 5 as shown in FIGS. 4 and 5, and a magnetic induction iron core 412 wound around the plurality of magnetic winding coils 411. It is made of a stator 41 and the bearing 43 so as to be rotated by the magnetic field generated from the stator 41 is fixed to one end of the rotary blade (2) and a permanent magnet of a plurality of N pole and S pole It consists of a rotary ring 42 fixed to the inner diameter (421).

In addition, in order to rotate the rotary blade (2) using the external power source (4 ') from the rotary ring 42 mounted on the circumferential surface of the bearing 43 coupled to the center tube (5) as shown in FIG. A drive tube 44 protruding and extending outward from the inlet 11 of the outer casing 1, a drive motor 48 seated on a bracket 47 supported on the outer casing 1, and the drive motor 48. It comprises a pulley 45 and a belt 46 for transmitting a rotational force in contact with the circumferential surface of the drive tube 44 fixed to the rotating shaft of the).

In addition, the method of transmitting the power of the drive motor 48 to the drive tube 44 is not limited to that made through the belt 46, but it can be found that the design can be used by changing the conventional gear type or the chain type. .

In addition, it is noted that it is possible to substitute a prime mover using fuel in a place where power supply is difficult in place of the drive motor 48 of the external power source 4 '.

In addition, as shown in FIGS. 4 and 6, a plurality of through-holes 61 are provided on the circumferential surface of the center tube 5 so that air flowing into the air passage 51 of the center tube 5 flows into the blowing space 13. Perforations to increase the air volume is made to be continuously discharged to the discharge port (12).

In addition, as shown in FIG. 12, a heat exchanger 34 using any one of a refrigerant, a high temperature fluid, or a heating element to generate cold air and warm air in front of the air passage 51 of the blower space 13 or the central pipe 5. After disposing to change to cold or warm air is made to discharge to the outside through the discharge port (12).

In the drawing, reference numeral 3 denotes a protection net, and 91 denotes switches mounted to the base 9 to supply and terminate power to the internal motor 4 and the external power source 4 '.

Next, the operation of the present invention configured as described above will be described.

The present invention is supplied to the magnetic field winding coil 411 of the stator 41 when the power supply by operating the operation switch 91 to use the drive of the internal motor 4 as shown in Figure 3, the magnetic field generated at this time And the rotor blade 2 is rotated by the repulsive force of the permanent magnet 421 fixed to the rotary ring 42, the air moves from the inlet 11 to the blowing space 13 by the rotation of the rotary blade (2). After it is discharged to the discharge port (12).

According to the present invention, the air blowing space 13 may be parallel to the air inlet 11 and the air outlet 12 and may be narrowed toward the outlet 12. The narrowed blower space 13 causes a greater air pressure difference. Accordingly, the filling space 13 narrowed toward the discharge port 12 will be described as an example.

In the process, the blower space 13 is connected to the discharge port 12, the space is narrowed, so that the air discharged from the discharge port 12 is to transmit the air to the far because the flow rate increases, the air discharged from the discharge port 12 Due to the increase in the flow rate of the rear tube of the center tube (5) is pulled out and discharged together to increase the air flow rate and wind speed, so that the continuous air movement can be made to increase the blowing force.

In addition, in the case of using the drive unit of the external power source 4 'as shown in Figure 6 to rotate the drive tube 44 through the pulley 45 and the belt 46 to the rotational force of the rotary shaft of the external power source 4'. , The rotation of the drive tube 44 soon leads to the rotation of the rotary blade (2), at which time the rotary ring 42 fixed to the rotary blade (2) is smoothly rotated with the aid of the bearing 43. The rotary blade 2 sucks air from the inlet 11 and moves to the blower space 13, and the moved air is discharged from the discharge port 12 at the tip of the blower space 13 where the space is narrowed. The flow rate increases and delivers the air far away. At this time, the rear airflow of the center pipe (5) to the increased flow rate of air discharged from the discharge port 12 is pulled into the induction air passage (51) and discharged together so that the air volume and As the wind speed is increased, the continuous air movement is made, thereby increasing the blowing force.

2 and 4, when a plurality of through holes 61 are drilled in the center tube 5, air introduced into the induction air passage 51 of the center tube 5 is blown through the through holes 61. Since the air flows into the space 13 and is mixed with the air supplied to the inlet 11, the air volume is increased to the discharge port 12. The increase of the air volume and the increase of the discharge flow rate are the movement of the rear airflow of the center pipe 5. This is more smooth, and discharged together with the air discharged to the discharge port 12, so that the air flow rate and the wind speed is increased so that the continuous air movement is made it is possible to increase the blowing force.

8 and 9 show a state in which the air filter is attached to the induction air passage (51). Desorption methods and mechanisms have not been described.

10 and 11 illustrate a state in which the ice pack 33 is attached to the induction air passage 51 through the ice pack holder 37.

12 is a view in which the heat exchanger 34 and the moisture nozzle 35 are installed. The heat exchanger 34 is connected to a power source to generate heat, and when it is operated, an air temperature control is possible. The moisture nozzle 35 typically discharges moisture generated from the ultrasonic humidifier. Insertion and detachment of the ultrasonic humidifier have not been described.

FIG. 13 relates to a blower purging the second induction air passage 100 according to the present invention. An apparatus having one induction air passage as described above according to the present invention is optionally referred to as a first induction air passage blower 10. The detailed description of FIG. 13 is to install the second induction air passage 100 horizontally on top of the first induction air passage blower 10 installed vertically. The second induction air passage 100 is configured to discharge air guided through the second induction air passage inner space 101 to the second discharge port 102. The air discharged to the second discharge port 102 amplifies the amount of air movement by inducing surrounding air as described above.

Current products on the wingless fan market use many spacers to shape the nose face and the very precise discharge port and to maintain the shape of the discharge port to induce ambient air. This leads to cost increase and energy loss. The through hole 61 formed in the second guided air passage 100 is installed at the inlet side of the outlet of the rapid air flow. Although the inlet may not be narrowed, the second discharge port 102 of the second induction air passage 100 preferably has a shape in which the inlet is narrowed.

FIG. 14 shows a plasma dust collector installed inside the base 9 in the blower 700 having the second guided air passage. At this time, the control method and detachment method of plasma are not explained.

FIG. 15 shows that the dehumidifier is installed in the base 9 in the blower 700 having the second induction air passage. The dehumidifier compresses gas from the compressor 302 and discharges cold air from the radiator 303. At this time, condensation occurs on the surface of the radiator to form water droplets 304. The condensed water droplets 304 are collected by the collecting device 305. This also does not explain the control and collection method of the dehumidifier.

Therefore, the present invention uses the axial rotary blade (2), even if the drive of the rotary blade (2) in any one of the configuration of the internal motor 4 or the external power source (4 ') from the rotary blade (2) There is no resistance to the flow of air to be moved, and the structure of the blower space 13 and the discharge port 12 between the outer casing 1 and the center tube 5 is discharged to the discharge port 12 because the Bernoulli principle can operate As the moving speed of the air increases and the air pressure decreases, the air in the air passage 51 of the center tube 5 is attracted to the air having a high pressure, and the air of the high pressure flowing into the center tube 5 is caught. It is a very simple and economical configuration that can be moved smoothly along the center tube (5) is not there is mixed with the low-pressure air discharged to the discharge port 12 to increase the blowing force.
