Description

[0001] BLOWER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fan apparatus, and more particularly, to a fan apparatus used for removing foreign matter from a human body or a work mechanism.

Generally, a clean zone is a space where there is no dust and is isolated or isolated from the outside. As a clean room that manufactures an ultra-dense integrated circuit and a laboratory that treats minute genes in cells such as genetic engineering, It has a wide range of applications in areas of influence.

One of the environmental conditions for forming such a clean zone is the presence of dust, which should not be invisible to the naked eye. Therefore, the clean area should be isolated from the outside to prevent dust from entering from the outside, and a device must be installed to remove the foreign bodies of the human body or work equipment coming into the area from outside the door. Also, in a workplace with many foreign objects, such as dust, equipment may be required to remove foreign matter to remove dust adhering to the worker or work implement after the work is completed.

A large air conditioner is generally used to remove foreign matter from a human body or a working instrument. Such an air conditioner may be attached to a wall or a ceiling, and a blower may be sprayed to the entire object through a certain space. At this time, a relatively strong airflow blows out the entire object to remove foreign matter, which may be harmful to the human body or work equipment.

Accordingly, although a blower such as a compressor capable of removing foreign substances is used, there is a problem that the output is not easily adjusted, and there is a problem that damage is caused by damaging the eardrum of the worker due to excessive noise.

Meanwhile, the connection hose or the nozzle may be connected to the blower to remove the foreign substance locally. However, there is a problem in that the nozzle of the nozzle is heated by the air to be sprayed, resulting in injury to the operator.

In addition, the removed foreign matter may be splashed in a direction in which the nozzle exists, which may result in mixing of the discharged air with foreign matter.

1 is a perspective view showing a blower 1 according to an embodiment of the present invention.

Referring to Fig. 1, the blowing apparatus includes a main body 100, a connecting member 200, and a nozzle 300. The air blowing apparatus sucks outside air into the main body 100 to cool and purge the sucked air, and discharges the air through the connecting member 200 and the nozzle 300 again.

FIG. 2 is an assembled view of the main body 100 of the fan apparatus 1 according to the embodiment of the present invention.

Referring to FIG. 2, the main body 100 includes a housing (see 110 in FIG. 1), a first filter 120, a blower 160, a motor 140, a cooling fan 150, a second filter 130, And a sound absorbing material 180. The main body 100 sucks outside air through the blower 160, the first filter 120, and the second filter 130 installed in the housing 110 to purify and discharge the air.

The housing 110 is a passage for purifying the external air to blow air through the connecting member 200 and the nozzle 300. According to an embodiment of the present invention, the first filter 120, the blower 160, the motor 140, the cooling fan 150, and the second filter 130 are provided in the housing 110.

The housing 110 includes an upper plate 112, a side plate 116, and a lower plate 114. The upper plate 112, the side plate 116 and the lower plate 114 are coupled to each other to form a hexahedron-like shape. The first filter 120, the blower 160, the motor 140, A space where air can flow is formed in addition to the space where the first filter 150 and the second filter 130 are installed.

The upper plate 112 has a hole 113 through which external air enters and exits and a first filter 120 is coupled to the hole 113. According to one example, the holes 113 may be formed to be offset in one direction of the upper plate 112, and the first filter 120 is coupled adjacent to the inner surface of the upper plate 112.

A hole 115 may also be formed in the lower plate 114. The hole 115 passes through the connecting member 200 through which the air discharged from the blower 160 flows.

The side plate 116 connects the upper plate 112 and the lower plate 114 and forms an enclosed space from which the air can flow. The lower plate 114 and the upper plate 112 may be coupled to the side plate 116 in a male-female engagement.

According to one example, a housing 110 formed by the top plate 112, the bottom plate 114 and the side plates 116 includes a first filter 120 coupled to the top plate 112, The motor 140, the blower 160 and the second filter 130 may be sequentially disposed toward the lower plate 114. That is, the blower 160, the motor 140, and the cooling fan 150 can be disposed between the first filter 120 and the second filter 130 at a considerable distance.

The housing 110 may be hermetically sealed except for the holes 113 formed in the upper plate 112 as shown in FIG. That is, the air introduced into the housing 110 can be introduced only through the holes 113 formed in the upper plate 112. The cooling fan 150, the motor 140, the blower 160, and the second filter 130 are connected to the inside of the inflow pipe 160 of the blower 160, . Therefore, the cooling performance of the motor 140 can be remarkably improved due to the strong air flow inside the housing 110.

The first filter (120) and the second filter (130) are purifying filters for removing foreign substances from the air. The first filter 120 is coupled to a hole 113 through which external air is introduced into the housing 110 to primarily remove foreign matter and the second filter 130 is connected to the suction port 164 of the blower 160 Thereby removing foreign matter from the air that is secondarily introduced into the blower 160.

The blower 160 is an apparatus for sucking and discharging outside air, and includes an impeller 162 rotating in the circumferential direction. The impeller is coupled to the motor 140 and driven. As the impeller 162 rotates, the air is sucked through the suction port 164 of the blower 160 and the air flows in the direction of the outer side of the impeller 162 while rotating along the impeller 162, (Not shown).

The cooling fan 150 cools the motor 140 driving the impeller. The cooling fan 150 is air-cooled to cool the motor 140 by forcibly blowing air toward the motor 140 so that the air having passed through the first filter 120 and having foreign substances removed is supplied to the motor 140 Inject. Accordingly, it is possible to prevent foreign substances from adhering to the motor 140, which makes it possible to maintain and repair the motor 140 advantageously.

Since the motor 140 is disposed inside the housing 110 where the strong air flow is generated by the blower 160, the motor 140 can be cooled even when the cooling fan 150 is not attached. However, By this addition, the cooling performance can be further improved.

As shown in FIG. 2, a fixing plate 170 may be provided between the second filter 130 and the blower 160 to fix the second filter 130. The second filter 130 may be directly coupled to the suction port 164 of the blower 160 but the first hole 172 may be formed in the fixing plate 170 to directly communicate with the center portion of the impeller 162, 2 filter 130 is coupled to the first hole 172.

The fixing plate 170 may be installed such that the space in the housing 110 is divided into a space in which the blower 160 and the motor 140 are disposed and a space in which the second filter 130 is installed. A connection member 200 connected to the blower 160 and a second hole 174 through which air purified through the first filter 120 can pass are formed on one side of the fixing plate 170.

The fan unit 1 according to an embodiment of the present invention may include a sound absorbing material 180 for removing noise of the motor 140 and the blower 160 in the housing 110. The sound absorbing material 180 is wrapped around the inner surface of the side plate 116 to block the noise in the housing 110. The sound absorbing material 180 may be formed of a porous material having an irregular convex shape and may prevent noise generated inside the housing 110 as well as conduction of heat generated in the housing 110 .

3 is a perspective view showing a connecting member 200 and a nozzle 300 of the blower 1 according to the embodiment of the present invention.

Referring to FIGS. 2 and 3, the connecting member 200 is coupled to the jetting port 166 of the blower 160 and extends to the outside of the housing (see 110 of FIG. 1). The connecting member 200 forms a flow path through which the air is discharged to the nozzle 300 through the blower 160. The connecting member is formed of a flexible material so that air can be freely sprayed to the human body or the instrument in a desired direction.

The nozzle 300 is provided at an end of the connecting member 200 and includes an outer tube 310, a flow pipe 320, a jetting port 330, and a protective cap. The nozzle 300 also includes a handle 350 and a hooking ring 360 coupled to the outer tube 310.

4 is a view showing a nozzle 300 of a blower 1 according to an embodiment of the present invention.

Referring to FIG. 4, the nozzle 300 has a double pipe connecting the connection member 200 and the injection port 330. The nozzle 300 is formed by an outer pipe 310 communicating with a flow path of the connecting member 200 and having a flow pipe 320 through which the air flows and an outer pipe 310 surrounding the flow pipe 320 in a spaced apart manner. That is, the outer tube 310 does not directly touch the flow pipe 320, but has an empty space therebetween, so that the outer tube 310 is not heated by the frictional heat generated by the air flowing along the flow pipe 320.

The injection port 330 is provided at an end of the outer pipe 310 and the flow pipe 320 and communicates with the flow pipe 320. In addition, the injection port 330 has a shape in which the diameter gradually decreases along the direction in which the air is discharged. This serves to increase the speed of air blowing by reducing the size of the outlet through which the air is discharged.

The protective cap 340 surrounds the injection port 330 and has a shape in which the diameter gradually increases along the direction in which the air is discharged. Accordingly, the protection cap 340 prevents foreign matter, which is removed by the air blown by the injection port 330, from splashing toward the injection port 330 and adhering to the air again. Also, the protection cap 340 may be provided with a transparent material, and it is easy to see that the foreign matter adheres to the protection cap 340.

The outer tube 310 of the nozzle 300 may be provided with a handle 350 and a hooking ring 360. 4, the end of the handle 350 may be bent toward the opposite direction of the injection port 330. As shown in FIG. The hooking ring 360 is provided to hang the connecting member 200 and the nozzle 300 when the blower 1 is not used. The hook ring 360 can be manufactured by forming a hole 362 in a plate protruding in the radial direction of the outer tube 310, as shown in Fig.

As described above, in the air blowing apparatus 1 according to the embodiment of the present invention, the first filter 120 and the second filter 130 are installed in the housing (see 110 of FIG. 1) And a motor 140 for driving the blower 160 to be sucked and the impeller 162 in the blower 160 are installed. The fixing plate 170 is installed in the housing 110 to divide the space in which the first filter, the blower 160 and the motor 140 are installed and the space in which the second filter 130 is installed, It has the feature to speed up.

In addition, the nozzle 300 is provided at the end of the connecting member 200 so that the pressure of the air discharged from the main body 100 under a strong pressure is further increased. The tubular shape of the nozzle 300 is provided in a double structure, The outer tube 310 is separated from the flow tube 320 through which the outer tube 310 flows. Therefore, the nozzle 300 has a feature of preventing heat transfer to the outer peripheral portion.

When the air blowing apparatus 1 having the above features is operated, the following air flow is formed.

5 and 6 are schematic views showing the direction of air flowing in the main body 100 of the air blowing apparatus 1 according to the embodiment of the present invention.

5 and 6, when the impeller 162 of the blower 160 is rotated by the motor 140, external air is blown into the holes 113 of the upper plate 112 by the rotational force of the impeller 162, (Refer to 110 in FIG. 1) through the first filter 120 coupled to the housing 120 (see FIG. The air introduced by the strong suction force of the blower 160 quickly flows into the suction port 164 of the blower 160 through the second hole 130 of the fixing plate 170 through the second filter 130. The air introduced into the blower 160 is discharged to the discharge port 166 through the flow path of the blower 160 via the impeller 162.

At this time, the motor 140 installed in the housing 110 is cooled by the fast flow of the air flowing in the housing 110. That is, the motor 140 is cooled not only by the cooling fan 150 but also by the air flowing inside the housing 110 by the blower 160. The motor 140 installed in the housing 110 is cooled faster than the motor 140 provided outside the motor 140 so that the load of the motor 140 can be blocked and the performance of the blower 160 can be further enhanced.

7 is a cross-sectional view showing a nozzle 300 of a blower 1 according to an embodiment of the present invention.

The air discharged from the main body 100 is discharged to the outside through the connecting member 200 and the nozzle 300. Particularly, as described above, air is rapidly discharged through the flow pipe 320 installed in the outer pipe 310 of the nozzle 300, and is rapidly injected through the narrowed outlet of the injection port 330.

The nozzle 300 is provided with a double structure, in particular, the outer tube 310 and the flow tube 320 are spaced apart from each other, thereby preventing heat from being transmitted from the flow tube 320 to the outer tube 310.

Also, as described above, when the foreign matter removed by the air ejected from the ejection port 330 jets in the direction of the ejection opening 330, the protection cap 340 blocks the foreign matter from being mixed into the air to be ejected.

As described above, the air blowing apparatus according to the embodiment of the present invention has a double filter structure and effectively removes foreign matter in the air to be blown, and the motor 140 driving the blower 160 is disposed inside the housing (see 110 in FIG. 1) Thereby enhancing the performance of the blower 160 by cooling the motor 140 with a rapid air flow in the housing 110. A noise absorbing material 180 is installed in the housing 110 to remove noise from the motor 140 and the cooling fan 150. The outer periphery of the nozzle 300, that is, the outer tube 310, is heated by the air injected through the nozzle 300 due to the outer tube 310 surrounding the channel tube 320 in the nozzle 300 And to protect workers.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
