Description

Fan for house {An Equipment of a ventilating used in house}

The present invention relates to a house ventilator, and more particularly, to a house ventilator capable of controlling the house internal environment while actively coping with the house internal and external environment, and remotely controlling the same.

House is a generic term that refers to a house where livestock are raised or a plastic house where crops are grown. It means a building with a relatively simple structure compared to a general house.

The house is equipped with vents to ventilate the air inside the house to provide a comfortable environment for livestock and crops to grow. The ventilation hole may be formed of an opening pre-installed in the house to roll up a portion of the vinyl forming the exterior of the house and penetrate one side of the house with the outside or have a predetermined size. The ventilation holes allow the air inside the house and the outside air to be circulated by natural wind flow, thereby controlling the temperature, humidity, and the like in the house.

However, since the ventilation hole is only a simple opening which is installed to communicate with the outside of the house, the inside of the house is inevitably created by natural temperature and wind. In other words, the house in which the ventilation hole is formed has a limitation in that it is not possible to actively control the amount or temperature of the air circulated and to create the environment inside the house according to the environmental conditions facing the outside.

In order to solve this problem, the house is provided with a fan for forcibly blowing air. And the ventilator is installed in the ventilation hole of the house formed to communicate with the outside as described above to adjust the environment inside the house by forcibly circulating the air inside the outside air.

The ventilator can circulate the air inside the house forcibly compared to the house in which only the above-described ventilation hole is formed, and thus, there is an advantage of actively creating an environment inside the house.

However, as the fan is also installed in the vent formed in the house, the vent is not completely sealed, so even though the vent is not operated, air flow is generated through the vent. Therefore, there is still a problem that the house in which the ventilator is installed does not have full control over its internal environment.

On the other hand, such a house is generally composed of a weak material such as a frame in the form of a pipe and vinyl covering the frame. Therefore, it is very vulnerable to large environmental changes outside the house. For example, if a typhoon or heavy snow occurs, the house may be damaged or collapsed greatly by wind and snow forces. This proves that the house is almost defenseless as a means to actively cope with external environmental changes.

As such, since the house does not actively cope with the internal and external environment of the house as described above, the applicant has come up with the present invention that can manage the house more efficiently while solving the above problems.

Accordingly, it is an object of the present invention to provide a house ventilator that can cope with the house interior and exterior environment.

Another object of the present invention is to provide a house ventilator capable of remote control to cope with the house environment more actively because it can remotely control the internal and external environment of the house with a mobile phone.

The above object is one embodiment of the present invention, a housing formed with a ventilation port; A blowing fan installed at the ventilation hole and having a pair of fans; A motor providing a driving force to the blowing fan; And it can be achieved by a house ventilator including an opening and closing operation unit for the blowing fan to seal the ventilating opening when the motor is not in operation, and the blowing fan to rotate while opening the ventilating opening when the motor is operated.

Here, the blowing fan may include a first fan having a plurality of first blades spaced apart from each other; And a second fan spaced apart from each other and coupled to the motor and rotatably coupled to the first fan.

The opening and closing operation unit may include a rotation disc fixed to the first fan and rotatably coupled to the second fan, and a movement control member for adjusting a moving range of the rotation disc and the second fan.

The movement control member, at least a pair of long holes are formed to face each other along the inner circumferential direction of the rotating disk; A stop pin fixed to the second fan while being movably inserted into the long hole; And one side may include a torsion spring is fixed to the rotating disk and the other side is fixed to the second fan.

It may further include a bent portion coupled to at least one blade of the first fan or the second fan.

The motor may be a waterproof motor.

In order to achieve the above object, the present invention is installed in a house of a different form and the housing is formed with a ventilation hole communicating with the outside; A blower fan installed at one side of the ventilation hole and having a double wing part which rotates while closing the ventilation hole during non-operation and opening the ventilation hole during operation; A motor providing a driving force to the blowing fan; An opening and closing operation unit for overlapping or unfolding the double wing of the blowing fan; A control unit for operating the blowing fan according to the internal and external environment of the house; And it provides a ventilator for the remote control including a remote control unit for remote monitoring the control unit.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

1 is a perspective view of a house ventilator of the present invention, Figure 2 is an exploded perspective view of the house ventilator of FIG.

As shown in these drawings, the house ventilator 1 according to an embodiment of the present invention has a double housing for circulating air by selectively opening and closing the housing 10 and the ventilation hole 10a in which the ventilation holes 10a are formed. It may include a blowing fan 20 having a wing portion 21, and a motor 30 for rotating the blowing fan 20.

The housing 10 is a part constituting the main body of the fan 1, and the housing 10 is provided with a ventilation opening 10a for communicating the inside and the outside of the house (not shown). In this embodiment, the housing 10 is formed in a hollow pipe shape to form a circular ventilation opening 10a therein. Of course, the shape of the housing 10 is not limited thereto and may be variously modified.

In the ventilation opening 10a formed in the housing 10, the upper portion thereof is an outlet through which air flows out of the house when the blower fan 20 rotates, and the lower portion thereof is an inlet for air. On the contrary, when the blowing fan 20 reversely rotates, the upper portion of the vent 10a will be an inlet for air and the lower portion of the vent 10a will be an outlet for air.

In addition, the housing 10 may be installed on the ceiling or the side of the house, such that an opening (not shown) is formed in a size corresponding to the size of the housing 10 so that the housing 10 is installed in the opening. It is desirable to. Accordingly, the house can be in communication with the outside through the ventilation opening (10a) of the housing (10).

In addition, the housing 10 is preferably made of stainless steel or plastic so as not to be corroded by moisture inside the house or rainwater outside the house.

The blowing fan 20 is installed in the housing 10, more specifically, the ventilation hole 10a. The blowing fan 20 may selectively open and close the ventilation opening 10a, thereby sealing the inside of the house from the outside or circulating air inside and outside the house.

That is, the blowing fan 20 is installed in the upper portion of the ventilation port 10a as shown in FIG. 1 to seal the ventilation port 10a when not in operation. And the blowing fan 20 is rotated while opening the vent (10a) during operation (see Fig. 5).

The blowing fan 20 is provided with a double wing 21 formed of a first fan 23 and a second fan 25. The double wing part 21 may seal or open the ventilation hole 10a because the first fan 23 and the second fan 25 may be unfolded or stacked on each other. Detailed description thereof will be described later.

A motor 30 is provided below the blowing fan 20 to provide driving force to the blowing fan 20. The motor 30 is disposed in the housing 10 with the shaft 31 facing the upper portion of the ventilation port 10a. And the blower fan 20 located in the upper portion is coupled to the shaft 31 of the motor 30.

Here, the motor 30 is preferably used a forward / reverse motor capable of forward or reverse rotation. The motor capable of forward and reverse rotation can selectively manipulate the rotation direction of the blower fan 20 so that air can be introduced into the house through the air vent 10a or the air inside the house can be discharged to the outside as needed. .

On the other hand, when the general motor 30 is used for a long time, foreign substances such as rust are generated while being corroded by moisture. Such foreign matters are circulated by the blowing fan 20, which may contaminate the inside of the house.

Therefore, it is preferable to use a waterproof motor as the motor 30 in the present invention. When the waterproof motor is used as the motor 30, since the corrosion of the motor 30 can be prevented, the house internal environment can be kept comfortable for a long time.

The motor 30 may be fixedly installed in the housing 10 by the foreign matter blocking member 15. The foreign material blocking member 15 is manufactured in a size corresponding to the ventilation opening 10a in the form of a grill formed with an empty space in the center thereof, and thus, the housing 10 and the motor 30 through coupling means such as bolts and welding. ).

That is, the foreign matter blocking member 15 together with the motor 30 in a manner of placing and fixing the motor 30 at the center of the foreign matter blocking member 15 and coupling an outer circumferential portion to the inner wall of the housing 10. It is fixed inside the housing 10.

In addition, since the foreign matter blocking member 15 is manufactured in the form of a grill, air may smoothly flow in or out of the ventilation hole 10a even if foreign matter is blocked. That is, when a leaf or a float of a plant inside the house enters the ventilation hole 10a together with the air, the foreign matter blocking member 15 may flow only the air while preventing the foreign material from passing through the foreign matter.

Therefore, the foreign matter blocking member 15 may prevent the shaft 31 or the blower fan 20 of the motor 30 from being damaged by the foreign matter. In addition, since the foreign matter blocking member 15 can block foreign matter from entering the house from the outside, the environment inside the house can be maintained more comfortably.

In addition, an air guide 17 coupled to the inside of the ventilation hole 10a and guiding the flow of air is installed below the housing 10. The air guide 17 has a plurality of blades 17a arranged radially. Therefore, the air passing through the ventilation port 10a can be circulated into the house and the outside while being guided quickly and accurately in the vertical direction of the housing 10 through the air guide 17.

On the other hand, the present invention is coupled to the blowing fan 20, the double wing portion (21) of the double wing 21 of the blowing fan 20 to be opened or folded, so as to selectively open and close the ventilation port (10a) of the housing 10 ( It further comprises an opening and closing operation unit 40 for operating the opening and closing of 21).

Hereinafter, the configuration of the opening and closing operation unit 40 will be described in detail, and the above-described double wing 21 will be described in more detail.

3 is an exploded perspective view of the blowing fan of FIG. 2, FIG. 4 is a view for explaining the opening and closing operation of the blowing fan of FIG. 3, and FIG. 5 is a perspective view illustrating a state in which the blowing fan of FIG. 2 is nested.

As shown in FIG. 3, the double wing 21 of the blower fan 20 of the present invention includes a first fan 23 disposed above and a lower part of the first fan 23 disposed above the motor. It consists of a second fan 25 coupled to the shaft 31 of (30).

For reference, the meaning of the word 'unfolded' which will be frequently used in the future is arranged side by side so that the first fan 23 and the second fan 25 constituting the double wing portion 21 eliminate each open space. It means the state. 1 and 2 show the unfolded double wings 21.

Here, the double wing 21 is in an unfolded state when the blowing fan 20 does not rotate (in the non-operation of the motor 30), whereby the ventilation opening (10a) of the housing 10 is closed Becomes

On the contrary, the word 'stacked' means that the first blades 23a of the first fan 23 have a large contact area between the first fan 23 and the second fan 25 of the double wing 21. And, it means a state in which the second blades 25a of the second fan 25 located below are overlapped. In this case, open spaces exist between the first blades 23a and the second blades 25b overlapping the first fan 23 and the second fan 25. The double wing 21 shown in FIG. 5 shows a superimposed state.

Here, the double wing portion 21 is superimposed when the blowing fan 20 rotates, and when the double wing portion 21 is superimposed, the vent opening 10a of the housing 10 is opened.

Hereinafter, the first fan 23 and the second fan 25 constituting the double wing 21 will be described in more detail.

As shown in FIG. 3, the first fan 23 is located outside the upper portion of the vent 10a of the housing 10. The first fan 23 may include a central body 23b and a plurality of first blades 23a radially coupled along the circumferential direction of the central body 23b.

The central body 23b is manufactured in the form of a cylinder having a lower opening, that is, a bowl, to form a body of the first fan 23. The first blade 23a is radially coupled to the outer circumferential surface of the center body 23b so that a plurality of the first blades 23a are spaced apart from each other. Therefore, an open space is formed between the plurality of first blades 23a, and the second blade 25a of the second fan 25 is positioned in the open spaces, such that the first fan 23 and the first fan 23 are formed. The two fans 25 may be combined to unfold with each other.

A plurality of bolt holes 24b are formed in the outer circumferential surface of the center body 23b, and the bolt holes 24b are coupled to the rotating disc 41 to be described later with the center body 23b being inserted into the bolt 24a.

The second fan 25 includes a center plate 25b and a plurality of second blades 25a radially coupled to the center plate 25b. The center plate 25b is manufactured in the form of a disc, and a rotating disc 41 to be described later is rotatably placed. The center plate 25b is formed with a shaft hole 25c to which the shaft 31 of the motor 30 is coupled, and a pair of stop pin coupling holes 43d to which the stop pin 43a to be described later is coupled.

The plurality of second blades 25a corresponding to the first fan 23 are coupled to the outer circumferential surface of the center plate 25b. Like the first fan 23, an open space is formed between the plurality of second blades 25a of the second fan 25.

Here, the number of the first and second blades 23a and 25a may be arbitrarily selected, and the size and shape may be modified according to the desired wind speed and wind direction. In the present exemplary embodiment, six blades 23a and 25a are disposed on the first fan 23 and the second fan 25 at equal intervals.

On the other hand, at least one of the blades (23a, 25a) of the first fan 23 and the second fan 25, the bent portion 26 for adjusting the wind direction during rotation of the blowing fan 20 is coupled It is preferable.

In the present embodiment, the bent portion 26 bent to be inclined downward to the first blade 23a of the first fan 23 is coupled. As shown in FIG. 5, when the double wing 21 is stacked, the direction of the wind is guided by the bent portion 26 coupled to the first blade 23a of the first fan 23.

In addition, when the double wing portion 21 is unfolded, as shown in FIGS. 1 and 2, the bent portion 26 of the first fan 23 is part of the second blade 25a of the second fan 25. It may also serve to seal the gap between the blades (23a, 25a) even more in contact with the lower surface of the).

On the other hand, the opening and closing operation unit 40 is coupled between the first fan 23 and the second fan 25 of the double wing portion 21 to manipulate the opening and closing to overlap or unfold the double wing portion 21 mutually. do.

The opening / closing operation part 40 is located between the first fan 23 and the second fan 25 and the rotation disc 41 for relatively rotatably coupling the first fan 23 and the second fan 25. And, it may be made of a movement adjusting member 43 for adjusting the movement range of the rotary disk 41.

Rotating disc 41 is located in the central region of the double wing 21, is fixed to the first fan 23 and is rotatably coupled to the second fan (25).

To this end, the rotating disc 41 has a bowl shape with an upper opening, and the center body 23b of the first fan 23 so that the center body 23b of the first fan 23 can be inserted into and coupled to the outside. It is made smaller than).

On the outer circumferential surface of the rotating disc 41, a plurality of bolt coupling holes 41a into which the bolts 24a are inserted at the time of engagement with the center body 23b of the first fan 23 is formed. Thus, since the first fan 23 and the rotation disc 41 are fixed to each other by being coupled by the bolt 24a, the rotation disc 41 may move integrally with the first fan 23.

In the center of the rotation disc 41 is formed a central shaft hole 41c into which the rotation shaft 31 of the motor 30 is inserted. The rotating disc 41 is placed on the center plate 25b of the second fan 25 and the shaft 31 of the motor 30 is coupled to the center hole 41c of the rotating disc 41. Rotatably coupled to 25).

The movement adjusting member 43 is coupled to the rotation disc 41 and the second fan 25 to limit the movement range so that the rotation disc 41 and the second fan 25 can be superimposed or unfolded with each other. .

As shown in FIG. 4, the movement adjusting member 43 may include at least a pair of long holes 43b formed in the rotating disc 41 and a second fan so as to correspond to the long holes 43b. A pair of stop pin coupling holes 43d formed in 25 and a pair of stop pin coupling holes 43d of the second fan 25 that are respectively movably inserted into the long holes 43b. It may include a stop pin (43a), and a torsion spring (43c) is fixed to one side of the rotating disk 41, the other side is fixed to the second fan (25).

The long hole 43b is formed so that the pair face each other to face each other along the inner circumferential direction on the lower surface of the rotating disc 41 so as to have a constant length. And the stop pin (43a) is inserted into each long hole (43b) is coupled to the stop pin coupling hole (43d) of the second fan 25 is fixed. Here, the head of the stop pin 43a is preferably formed larger than the width of the long hole 43b so that the stop pin 43a is not separated from the long hole 43b.

Therefore, when the rotation disc 41 rotates with respect to the second fan 25, the stop pin 43a is relatively movable along the longitudinal direction of the long hole 43b of the rotation disc 41. Thus, the rotation disk 41 is limited to the length of the long hole (43b) the moving range that can be rotated left and right. (For reference, it has been described above that the rotation disc 41 is rotatably coupled to the second fan 25 while being coupled with the shaft 31 of the motor 30.)

The torsion spring 43c has one end fixed to the bottom surface of the rotation disc 41 and the other end fixed to the top surface of the center plate 25b of the second fan 25, and the rotation range is limited as described above. Elastically supports (41).

Here, the torsion spring 43c is a state in which the first fan 23 and the second fan 25 fixed to the rotation disc 41 are unfolded with each other, and the rotation disc 41 is formed at the position constituting the double wing 21. It is preferable to apply elastic force to the. For convenience of description, the position of closing the ventilator 10a while the double wing 21 is unfolded is referred to as a "closed position", and the position of opening the ventilator 10a while the double wing 21 is nested is an "open position". It will be called '.

In the closed position, the stop pin 43a may be located at the end of one direction of the long hole 43b, and in the open position, the stop pin 43a may be located at the end of the other direction of the long hole 43b. Reference is made to the positions of the torsion springs 43c and the long holes 43b shown in FIG. 4 by dashed lines (open positions) and solid lines (close positions), respectively.

When the rotary disk 41 is rotated by applying a force counterclockwise (left) in the 'closed position', the stop pin 43a moves from one end of the long hole 41 to the other end. That is, the rotary disk 41 is moved to the 'open position' while the double wing portion 21 is placed in a superimposed state as shown in FIG.

At this time, when the applied force is released, the elastic restoring force of the torsion spring 43c is applied, and the rotation disc 41 rotates clockwise (right) to return to the closed position.

In this principle, when the blowing fan 20 is rotated by the motor 30, the rotation disc 41 moves to the 'open position' while the rotation disc 41 moves with respect to the second fan 25 by centrifugal force. That is, the double wing 21 is rotated while being converted to the nested state as shown in Figure 5 in the unfolded state.

When the blower fan 20 having the opening and closing operation unit 40 is not rotated by the motor 30, the double wing 21 is placed in an unfolded state so that the air blower 10a is sealed and the blower fan ( When the 20 is rotated, since the double wing 21 is placed in a superimposed state, the vent 10a of the housing 10 is opened.

As described above, since the house ventilator 1 of the present invention can operate to selectively seal or open the ventilator 10a, the air flow is generated through the ventilator when the ventilator is not operated. This can solve the problem of not having full control of the system.

Figure 6 is a block diagram of a house ventilator capable of remote control of the present invention.

Hereinafter, a house ventilator for remote control of the present invention that can control the environment inside and outside the house will be described.

The house ventilator for remote control of the present invention, as shown in Figure 6, the configuration of the above-described ventilator 1, the control unit 50 for controlling the operation of the blowing fan 20, and the state of the house It may be configured to include a remote control unit 60 that can control the control unit 50 while monitoring at a distance.

The controller 50 serves to manually or automatically operate the blowing fan 20 according to the internal and external environment of the house. The controller 50 may be implemented in the housing 10 to control the motor 30, or may be separately installed in the housing 10 and installed in the house.

The control unit 50 may include a temperature sensor 51, a wind speed meter 53, and a microcomputer 55.

The temperature sensor 51 measures the internal and external temperatures of the house. As the temperature sensor 51, a PT temperature sensor installed inside and outside the house may be employed. The temperature sensor 51 measures the temperature inside and outside the house, and transmits the measured temperature data to the microcomputer 55 to be described later to check whether the inside of the house is maintained at the set temperature. Therefore, since the house temperature measured by the temperature sensor 51 can be compared with the temperature set by the microcomputer 55, the controller 50 may control the operation of the blower fan 20 to maintain the set temperature inside the house. Can be.

An anemometer 53 is installed inside and outside the house to measure the wind speed inside and outside the house, respectively. An air flow meter 53 installed inside the house may measure the flow of air flowing into the house when the fan 1 operates, and air outside the house through the wind speed meter 53 installed outside the house. The flow rate can be measured.

The wind speed meter 53 transmits the measured wind speed data to the microcomputer 55, and can be effectively used when detecting a typhoon, which is a large environmental change outside the house. This will be described later.

And the microcomputer 55 receives the data measured from the above-described temperature sensor 51, the wind speed measuring instrument 53 serves to operate the fan 1 by comparing with the preset input data. That is, the microcomputer 55 rotates the blowing fan 20 by driving the motor 30 to maintain the set temperature, humidity, etc. in the house according to the comparative analysis of the data. Here, the microcomputer 55 receives and inputs an appropriate temperature, humidity, wind speed, etc. inside the house by the user.

The controller 50 configured as described above may be configured to directly control the operation of the fan 1 by using a button input method or the like. In addition, the controller 50 may control the operation of the fan 1 to automatically maintain the set data value while the environment inside the lower part compares data values, such as temperature and humidity, set in real time with the preset house data. Can be.

On the other hand, the remote control unit 60 allows a user located far from the fan 1 to control the control unit 50 by wireless to enable the control of the operation of the fan 1.

The remote control unit 60 includes an antenna 57 further included in the above-described configuration of the control unit 50, and a terminal 63 receiving and transmitting a signal to and from the control unit 50 through the antenna 57. It can be done by.

The antenna 57 is installed inside or outside the house, and data respectively measured from the temperature sensor 51 and the wind speed measurement meter 53 of the controller 50, data previously set in the microcomputer 55, The data signals analyzed through the microcomputer 55 may be transmitted to the terminal 63 or may receive a command signal from the terminal 63.

The terminal 63 may be a mobile phone capable of wirelessly receiving and transmitting signals through the antenna 57. In addition, the antenna 57 and the terminal 50 may be configured to transmit and receive two-way communication using a code division multiple access (CDMA) method.

Accordingly, the user can receive data on the temperature, wind speed, etc. inside the house at a distance from the house through the terminal 63 such as a mobile phone, and the user can receive a command signal for controlling the operation of the controller 50 through the provided data. By sending it, it becomes possible to operate or deactivate the fan 1.

7A and 7B are state diagrams of the use of the ventilator of FIG. 6. Hereinafter, a method of controlling the house fan of the present invention as described above in preparation for typhoon and heavy snow will be described with reference to the above-described drawings.

In general, the damage caused by the typhoon is known to be caused by the difference in the flow rate between the inside and the outside of the house. That is, as shown in FIG. 7A, when the typhoon wind passes the upper portion of the house H at a high flow rate, a negative pressure Po is generated at the upper portion of the house H to cover the house H. The frame is pulled out and thrown away.

In order to prevent the damage caused by the typhoon (Typhoon Wind) it is necessary to generate a negative pressure (Pi) inside the house to correspond to the negative pressure (Po) by the typhoon (Typhoon Wind).

Accordingly, when a typhoon (Typhoon Wind) occurs outside the house (H), the house fan (1) of the present invention installed on one side of the house (H) blows the fan 20 while opening the opening (10a) (H) It operates to discharge the air inside. And the amount of air to be discharged to the outside of the house (H) according to the flow rate of the typhoon (Typhoon Wind) measured through the wind gauge 53 installed outside the house (H) can be calculated.

When the air inside the house (H) is discharged to the outside of the house (H) by using the blowing fan 20 to correspond to the wind speed of the typhoon (Typhoon Wind) measured in this way, the typhoon (Typhoon Wind) inside the house (H) Since the negative pressure Pi corresponding to the negative pressure Po generated by this can be obtained, the vinyl and the frame of the house H can be prevented from being blown away by the typhoon wind. As a result, the house in which the house ventilator of the present invention is installed can reduce damage caused by typhoon wind.

On the other hand, the house is also damaged by snowfall. The damage of the house due to heavy snow, as shown in Figure 7b Snow (Hnow) is gradually accumulated in the upper portion of the house (H) as the pressure (Po) acts into the house (H) as the pressure of the house (H) It is caused by not winning. At this time, the damage caused by heavy snow is shown to increase even more because a large amount of snow (Snow) at once in a short time without the time to clear the snow (Snow) stacked on the upper part of the house (H).

Therefore, if the house (H) inside is maintained at a positive pressure (Pi, Positive Pressuer) of a certain size, despite the heavy snow load (Po) accumulated on the upper portion of the house (H) can withstand a long time.

To this end, unlike the above-described typhoon example, the air outside the house H is introduced into the air through the blowing fan 20 to generate a positive pressure Pi inside the house H. Since the house (H) is typically configured in the form of a dome (dome), when a positive pressure is generated inside the house (H) can make the house (H) more inflated like a balloon.

Therefore, the upper part of the house H, which maintains a positive pressure at a constant size, not only makes the snow slip more easily, but also the snow pressure accumulated on the upper part of the house H for a longer time. It will be able to withstand, thus freeing up time to remove Snow.

In addition, the present invention, of course, through the remote control unit 60 capable of remote control of the fan, the user of a long distance from the house (H) can also control the fan 1 in preparation for typhoons and heavy snow.

As described above, the present invention can cope with the internal and external environment of the house H more quickly because the ventilation port can be directly sealed or opened with a blowing fan.

In addition, since the remote control is possible, a long distance user can quickly respond to changes in the house (H) and the external environment.

Hereinafter, a preferred embodiment of the present invention with reference to the drawings, but the scope of the present invention is not limited thereto.

As such, the present invention is not limited to the above-described embodiments, and can be modified by those skilled in the art without departing from the spirit of the present invention, and such modifications will fall within the scope of the present invention.
