Description

AIR AMPLIFIER FOR DRY AND VENTILATION

The present invention relates to an air conditioner used for drying or ventilating a room, and more particularly, to an air conditioner that improves the ejection speed of compressed air to improve the ventilation performance and improves the structural emphasis of the ejection portion to improve durability Drying and ventilating fans.

In general, an air blower (AIR AMPLIFIER) is a device used for blowing indoor air to the outside to discharge polluted air to the outside to ventilate the room, or to dry the room by circulating indoor and outdoor air.

Particularly, in the shipbuilding industry, in order to dry paint inside the ships and blocks, it is possible to dry quickly when the outside air is well flowed. Therefore, it meets the purpose of non-sparking and dustproof Or for ventilation for protection of workers due to painting or welding work in an enclosed space, are widely used.

It is very important to maximize the KOANDA EFFECT by pulling out the compressed air at the output stage to maximize the surrounding air.

For the purpose of paint drying and worker ventilation in vessels, products capable of explosion-proof and dustproofing are mainly used. There are ONE-NOZZLE method and multi-NOZZLE method according to the ventilation method.

In the original nozzle method, a nipple (NIPPLE) having an ON / OFF valve is mounted at the front end of the air supply pipe, and the compressed air supplied from the air supply pipe is directly injected. In the case of such a circular nozzle system, since the compressed air is sprayed as it is, a lot of noise is generated, requiring installation of a silencer, and a consumption amount of compressed air is increased.

In the multi-nozzle method, a small nozzle having a small hole is disposed at the edge of the cylindrical pipe or in the center of the pipe, thereby increasing the amount of air blown by using the pressure difference generated when the compressed air is sprayed at high speed and high pressure. Such a multi-nozzle system has advantages of less noise compared with the original nozzle system, but it is very expensive.

Therefore, due to the problem of manufacturing cost of such an aerator, a circular nozzle type fan is still used in the field.

1 shows an example of a conventional air conditioner. In the conventional air conditioner shown in FIG. 1, a compressed air input port nozzle 20 is connected to the front end, and a compressed air An air hose (10) is provided with a ventilation part (40) to which a pipe with a closed end is connected to the other end of the compressed air air hose (10) And a plurality of compressed air spray nozzles 50 are formed.

1, the compressed air supplied through the compressed air air hose 10 is supplied to the pipe of the discharge portion 40 and is injected through the compressed air injection nozzle 50. [ At this time. The shape of the embers 40 is bent in a spiral shape so that the compressed air is widely blown to a predetermined surface area formed by the embers 40. [

However, since the ventilator shown in Fig. 1 is formed in such a structure that the pipe constituting the ventilation portion 40 is spirally extended in a state of no disconnection, the ventilation portion 40 is difficult to obtain high mechanical strength and the ventilation portion 40 ) In a uniform spiral shape. Therefore, the durability of the embers 40 is reduced and the manufacturing cost is inevitably increased.

2 shows another example of a conventional ventilator, showing the front shape of the ventral part 40 '. 2 is constituted by annular pipes 41 and 42 which are continuous without interruption, so that the problem of strength reduction of the fan shown in Fig. 1 can be solved. For reference, other configurations of the air hose and the like except for the discharge port 40 'are not greatly different from the configuration of the fan shown in Fig.

2 is formed to have a smaller area for spraying air relative to the spiral-shaped embers 40 (see FIG. 1), and therefore, the embossed portions 40 'formed on the same concentric axis are formed to have different diameters And a plurality of annular pipes (41, 42) are provided to widen the injection area. At this time, any one of the pipes 41 and 42 is supplied with the compressed air by the connecting portion 43 connected to the air hose 10 (see FIG. 1), and the other pipe 42 Is formed so that the compressed air is supplied by the connecting portion 44 which is connected to each other by the pipes 41 and 42.

However, since the discharge portion 40 'of the fan shown in FIG. 2 has a limitation in increasing the air injection area as compared with the spiral structure, there is a problem that the performance and the performance of the fan are deteriorated because the speed and air volume of the entire air are reduced.

FIG. 3 is a perspective view showing an air conditioner according to an embodiment of the present invention, FIG. 4 is a perspective view showing a shape of a recess of an air conditioner according to an embodiment of the present invention, and FIG. 5 is a cross- .

Referring to FIG. 3, the ventilator 100 of the present invention includes an air supply pipe 110 for supplying compressed air, an inflow nozzle 120 formed at an input end of the air supply pipe 110, A valve 130 for regulating the flow of compressed air flowing into the air supply pipe 110 and a spraying unit 130 for discharging compressed air, which is located at an output end of the air supply pipe 110, (140).

The inflow nozzle 120 may be formed by a NIPPLE which can be coupled to the pipe leading from the air supply pipe 110 and the external compressed air generating means by screws.

In the ventilator 100 according to the above configuration, the compressed air supplied from the compressed air generating means provided outside flows into the inflow nozzle 120, and the compressed air introduced into the inflow nozzle 120 is supplied to the air supply And is supplied to the jetting unit 140 through the pipe 110 to jet it. At this time, the amount of compressed air injected to the jetting unit 140 is adjusted through the valve 130 provided between the air supply pipe 110 and the inflow nozzle 120.

According to one embodiment of the present invention, the jetting unit 140 includes a LAVAL NOZZLE 150 which is coupled to a jetting hole 142 for jetting compressed air and increases the jetting speed of compressed air injected to the outside, Respectively.

Although the Laval nozzle 150 is similar in shape to a venturi nozzle, the venturi nozzle utilizes the phenomenon that the speed and pressure of the fluid are inversely proportional to the change in sectional area of the tube through which the fluid flows due to the principle of conservation of the incompressible fluid energy . 4 and 5, the Laval nozzle 150 according to the present embodiment has a length in the longitudinal direction through which the fluid passes and has a cross-sectional area from an inlet 152 at one end through which fluid is introduced The central throttling portion (THROTTLE) 154 that becomes narrower can be accelerated to the sonic state by the choked flow while passing the compressed air. Since the cross sectional area from the throttle part 154 to the discharge port 156 increases and the isentropic expansion occurs, the speed of the compressed air injected through the Laval nozzle 150 is accelerated to the supersonic speed SUPERSONIC.

The present invention is applied to the jetting portion 140 of the fan 100 using the principle of the Laval nozzle 150 relating to the compressible flow to maximize the velocity of compressed air injected through the jetting portion 140, Maximize the Coanda effect. Therefore, it is possible to increase the performance of the fan 100 by dragging the air around the jetting unit 140 more.

As shown in FIG. 3, the Laval nozzle 150 may be integrally formed in a shape protruding from a plurality of injection holes 142 formed in front of the jetting section 140. At this time, the Laval nozzle 150 is connected to the injection hole 142 by welding or by inserting the inlet 152 into the injection hole 142 of the injection part 140 Or a method of screw coupling, or the like.

3, the sprayer 140 is formed in an annular shape perpendicular to the direction in which the compressed air is injected, and is formed so that one side of the lower portion communicates with the inside of the tip of the air supply pipe 110 . However, the jetting part 140 of the present invention is not limited to such an annular shape, but can be applied to various structures such as spiral, polygonal, and linear shapes as well known in the art.

3, reference numeral 160 denotes a fixing means 160 for installing the fan 100 in an arbitrary place or space. The fixing means 160 may be constructed using a permanent magnet so that it can be easily attached and fixed to the hull of a ship manufacturing facility. In order to use the permanent magnet 160 as a non-magnetic material, a clamp CLAMP) can be applied.

Figure 6 shows the structure of the fan according to another embodiment of the present invention. 6, the jetting unit 140 of the ventilator 100 of the present invention includes a pipe adapter 155 protruding from a plurality of jetting holes 142 formed in the forward direction, And the Laval nozzle 150 of the previous embodiment is connected to the protruding end of the nozzle.

According to the present embodiment, the pipe adapter (PIPE ADAPTER) 155 has a general length of the pipe extended to a certain length, and may be integrally formed in the manufacturing process of the jetting unit 140, 142 by welding or the like. In this case, the structural strength of the portion projecting from the injection hole 142 of the injection portion 140 can be improved, so that damage or breakage of the injection portion 140 can be prevented, and the compressed air can be stably Can be formed. At this time, the Laval nozzle 150 can be joined by a method in which the inlet 152 side is welded to the tip of the pipe adapter 155 or inserted into the tip of the pipe adapter 155, .

7 shows the structure of the fan according to another embodiment of the present invention. Referring to FIG. 7, the jetting portions 140 and 240 of the fan 100 of the present invention may have a plurality of diameters, and a plurality of the jetting portions 140 and 240 may be disposed in front of and behind the diametric axis of the same room. As described above, since the plurality of jetting portions 140 and 240 having different diameters are disposed so as to be concentric with the jetting direction of the compressed air, the area for injecting the compressed air can be increased and uniform jetting can be achieved.

In addition, the plurality of jetting units 140 and 240 may be configured to transfer compressed air from the air supply pipe 110 through separate routes. That is, the sprayer 140 having a relatively large diameter is joined by welding or the like so that the lower end thereof is connected to the air supply pipe 110 as in the previous embodiment, and the sprayer 240 having a relatively small diameter As shown in the drawing, the lower end of the extension pipe 245, which extends upward from the air supply pipe 110 and supplies the compressed air, is welded to the air supply pipe 110, so that the two injection parts 140, 240 May be positioned on a concentric line perpendicular to the jetting direction.

For example, when the diameter of the jetting part 140 positioned at the front is increased and the diameter of the jetting part 240 positioned at the rear is decreased as shown in FIG. 7, the jetting parts 140, The compressed air injected toward the front of the air intake duct 240 does not reach a long distance but has excellent diffusibility. On the contrary, when the diameter of the jetting part 140 positioned at the front is relatively small, the arrival distance of the jetting air is disadvantageously deteriorated. Therefore, it is preferable to select a type suitable for the environment to which the fan 100 is applied in consideration of these two characteristics.

6 and 7, there is no difference from the configuration of the embodiment shown in FIG. 3 except for the jetting unit 140, so that repetitive description thereof will be omitted. The injection hole 242 and the Laval nozzle 250 of the injection unit 240 located at the rear in FIG. 7 have the same function and operation as those of the injection hole 142 and the Laval nozzle 150 described above.

The fan 100 of the present invention according to the present invention has a configuration in which the Laval nozzle 150 is applied to the jetting unit 140 to inject compressed air at supersonic speed to maximize the coanda effect to draw more ambient air to be ventilated So that the performance of the fan 100 can be maximized. Therefore, it is not necessary to manufacture the jetting unit 140 in a complicated shape such as a conventional helical structure, and it is possible to manufacture a general annular shape free from any disconnection, thereby providing a fundamental solution to greatly increase the structural strength.

Although the ventilator 100 for drying and ventilation according to the present invention has been described with reference to the embodiments shown in the drawings, it is merely an example, and various modifications and equivalents of other embodiments can be made by those skilled in the art . Accordingly, the true scope of the technical protection should be determined by the technical idea of the appended claims.
