Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air sweeping blade, an air guide frame and an air conditioner. Background Art

[0002] With the improvement of living standards, people's requirements for the quietness of household appliances are becoming increasingly stringent.

[0003] In the prior art, there is a gap between the rotating shaft and the shaft hole of the sweeping blade of the air conditioner. Therefore, the sweeping blade will vibrate and make noise during rotation, which makes it difficult to meet people's increasing expectations for a better life. Summary of the invention

[0004] The problem solved by the invention is that the wind sweeping blades vibrate and make noise during rotation.

[0005] To solve the above problems, an embodiment of the present invention provides a wind sweeping blade, which is used to be pivotally connected to an air guide frame, including a first rotating shaft and a second rotating shaft. The air guide frame includes a plurality of axial holes distributed along a vertical direction. The first rotating shaft and the second rotating shaft are respectively rotatably arranged in the corresponding axial holes. The central axis of the first rotating shaft and the central axis of the second rotating shaft are both parallel to the central axis of the axial hole, and the central axis of the first rotating shaft does not coincide with the central axis of the second rotating shaft.

[0006] The wind sweeping blade provided in the embodiment of the present invention has an eccentric arrangement of the first rotating shaft and the second rotating shaft, so that the first rotating shaft and the second rotating shaft are both in contact with the inner wall of the shaft hole, reducing the virtual position, thereby reducing the vibration of the blade during rotation and reducing the noise.

[0007] Optionally, the cross section of the shaft hole is circular, and the sum of the radius of the cross section of the first rotating shaft, the radius of the cross section of the second rotating shaft, and the distance between the central axis of the first rotating shaft and the central axis of the second rotating shaft is equal to the diameter of the cross section of the shaft hole. This allows the first rotating shaft and the second rotating shaft to contact the inner wall of the shaft hole at least at one point, thereby reducing the virtual position, reducing the shaking of the wind sweeping blade during the rotation process, and reducing the noise.

[0008] Optionally, the shaft hole includes a first side and a second side arranged opposite to the first side, and the first rotating shaft is arranged close to the first side in the initial state, and the second rotating shaft is arranged close to the second side in the initial state, so that the first rotating shaft and the second rotating shaft are in close contact with the shaft hole, thereby reducing the virtual position, reducing the shaking of the wind sweeping blade during the rotation process, and reducing the noise.

[0009] Optionally, the wind sweeping blade further includes a third rotating shaft, which is disposed in the shaft hole and vertically disposed between the first rotating shaft and the second rotating shaft, and the central axis of the third rotating shaft coincides with the central axis of the shaft hole. Providing the third rotating shaft can ensure that the wind sweeping blade rotates more smoothly.

[0010] Optionally, the first side is arranged close to the wind guide frame, and the second side is arranged away from the wind guide frame, so that the first rotating shaft and the second rotating shaft are more closely fitted to the inner wall of the shaft hole, the virtual position is reduced, the shaking of the wind sweeping blade during the rotation process is reduced, and the noise is reduced.

[0011] Optionally, an axis hole wall is arranged outside the axis hole, the axis hole wall surrounds the axis hole, and a notch of one-third of a circular ring is arranged on the axis hole wall, the first side is arranged close to the notch, and the second side is arranged away from the notch. This makes the first rotating shaft and the second rotating shaft fit more closely with the inner wall of the axis hole, reduces the virtual position, reduces the shaking of the wind sweeping blade during the rotation process, and reduces the noise.

[0012] An embodiment of the present invention further provides an air conditioner, comprising the wind sweeping blade provided by the embodiment of the present invention.

[0013] A wind guide frame is used to be pivotally connected to a wind sweeping blade, including a first rotating shaft and a second rotating shaft. The wind sweeping blade includes a plurality of axial holes distributed in a vertical direction. The first rotating shaft and the second rotating shaft are respectively rotatably arranged in the corresponding axial holes. The central axis of the first rotating shaft and the central axis of the second rotating shaft are both parallel to the central axis of the axial hole, and the central axis of the first rotating shaft does not overlap with the central axis of the second rotating shaft.

[0014] The wind guide frame provided by the embodiment of the present invention has an eccentric arrangement of the first rotating shaft and the second rotating shaft, so that the first rotating shaft and the second rotating shaft are both in contact with the inner wall of the shaft hole, reducing the virtual position, thereby reducing the shaking of the blades during rotation and reducing the noise.

[0015] Optionally, the shaft hole includes a first side and a second side arranged opposite to the first side, and the first rotating shaft is arranged close to the first side in the initial state, and the second rotating shaft is arranged close to the second side in the initial state, so that the first rotating shaft and the second rotating shaft are in close contact with the shaft hole, thereby reducing the virtual position, reducing the shaking of the wind sweeping blade during the rotation process, and reducing the noise.

[0016] An embodiment of the present invention further provides an air conditioner, comprising the air guide frame provided by the embodiment of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Please combine Figure 1 An embodiment of the present invention provides a wind sweeping blade 100 for being pivotally connected to an air guide frame 300 .

[0043] Please combine Figure 2 The wind sweeping blade 100 includes a blade body 110, a first rotating shaft 131 and a second rotating shaft 133. An axial hole 310 is provided on the wind guide frame 300. The first rotating shaft 131 and the second rotating shaft 133 are respectively rotatably installed in the corresponding axial holes 310. The first rotating shaft 131 and the second rotating shaft 133 rotate in the axial hole 310 to realize the rotation of the wind sweeping blade 100 around the central axis 16 of the axial hole 310.

[0044] In the embodiment of the present invention, the air guide frame 300 is provided with a plurality of shaft holes 310, the plurality of shaft holes are distributed in the vertical direction, the cross section of each shaft hole 310 is circular, the cross section of each shaft hole 310 has the same radius, the central axis 16 of each shaft hole 310 coincides, each first rotating shaft 131 is provided in a shaft hole 310, and each second rotating shaft 133 is provided in a shaft hole 310. Figure 3 In the embodiment of the present invention, an axial hole wall 310a is disposed outside the axial hole 310, and the axial hole wall 310a encloses the axial hole 310. Preferably, the axial hole wall 310a is in the shape of two-thirds of a circular ring, and the axial hole wall 310a is provided with a notch 310b in the shape of one-third of a circular ring. It can be understood that the first rotating shaft 131 and the second rotating shaft 133 are installed in the axial hole 310 through the notch 310b.

[0045] The “vertical direction” in the drawings corresponds to the MN direction, the M direction represents vertically upward, and the N direction represents vertically downward.

[0046] Please combine Figure 4 In the embodiment of the present invention, the first rotating shaft 131 and the second rotating shaft 133 are both arranged on the same side of the wind sweeping blade 100, and the first rotating shaft 131 and the second rotating shaft 133 are both eccentrically arranged. The central axis l1 of the first rotating shaft 131 is parallel to the central axis l6 of the shaft hole 310, and the central axis l2 of the second rotating shaft 133 is parallel to the central axis l6 of the shaft hole 310, and the central axis l1 of the first rotating shaft 131 does not overlap with the central axis l2 of the second rotating shaft 133.

[0047] In a preferred embodiment of the present invention, the shaft hole 310 includes a first side 313, 413 and a second side 315, 415, the first side 313, 413 and the second side 315, 415 are arranged opposite to each other, the first rotating shaft 131, 231 is arranged close to the first side 313, 413 in the initial state, and the second rotating shaft 133, 233 is arranged close to the second side 315, 415 in the initial state. The "initial state" refers to that the wind sweeping blade 100 is in the initial position.

[0048] Please combine Figure 5A and Figure 5B In a preferred embodiment of the present invention, the first side 313 is disposed close to the air guide frame 300 , and the second side 315 is disposed away from the air guide frame 300 .

[0049] Please combine Fig. 6A and Figure 6B In another embodiment of the present invention, the first side is disposed close to the notch 410b, and the second side is disposed away from the notch 410b.

[0050] Please combine again Figure 2In a preferred embodiment of the present invention, the wind sweeping blade 100 includes a third rotating shaft 135. The third rotating shaft 135, the first rotating shaft 131 and the second rotating shaft 133 are all arranged on the same side of the wind sweeping blade 100. The third rotating shaft 135 is arranged between the first rotating shaft 131 and the second rotating shaft 133 in the vertical direction. The third rotating shaft 135 is rotatably arranged in the shaft hole 310, and the central axis l3 of the third rotating shaft 135 coincides with the central axis l6 of the shaft hole 310.

[0051] In a preferred embodiment of the present invention, the central axis l1 of the first rotating shaft 131, the central axis l2 of the second rotating shaft 133, and the central axis l6 of the shaft hole 310 are located in the same plane. The first rotating shaft 131, the second rotating shaft 133, and the third rotating shaft 135 are all cylindrical, and preferably, the radius r1 of the cross section of the first rotating shaft 131, the radius r2 of the cross section of the second rotating shaft 133, and the radius r3 of the cross section of the third rotating shaft 135 are equal, and the central axis l1 of the first rotating shaft 131 and the central axis l2 of the second rotating shaft 133 are set to be axially symmetrical about the central axis l6 of the shaft hole 310.

[0052] It can be understood that the "cross section" is a cross section perpendicular to the central axis l1 of the first rotating shaft 131 and the central axis l2 of the second rotating shaft 133. The first rotating shaft 131 and the second rotating shaft 133 are regular cylindrical shapes, and their cross sections are circles with equal radius.

[0053] like Figure 4 As shown, in a preferred embodiment of the present invention, the radius r1 of the cross section of the first rotating shaft 131 is smaller than the radius r6 of the cross section of the shaft hole 310, and the radius r2 of the cross section of the second rotating shaft 133 is smaller than the radius r6 of the cross section of the shaft hole 310. The sum of the radius r1 of the cross section of the first rotating shaft 131 plus the radius r2 of the cross section of the second rotating shaft 133 plus the distance m1 between the central axis l1 of the first rotating shaft 131 and the central axis l2 of the second rotating shaft 133 is equal to the diameter d6 of the cross section of the shaft hole 310, that is:

[0054] r1+r2+m1=d6.

[0055] It can be understood that the radius r1 of the cross section of the first rotating shaft 131 and the radius r2 of the cross section of the second rotating shaft 133 are both smaller than the radius r6 of the cross section of the shaft hole 310, which reduces the contact area between the first rotating shaft 131 and the second rotating shaft 133 and the inner wall of the shaft hole 310, thereby reducing the resistance of the first rotating shaft 131 and the second rotating shaft 133 during the rotation process, making the rotation of the first rotating shaft 131 and the second rotating shaft 133 smoother.

[0056] It can be understood that the sum of the radius r1 of the cross section of the first rotating shaft 131, the radius r2 of the cross section of the second rotating shaft 133, and the distance m1 between the central axis l1 of the first rotating shaft 131 and the central axis l2 of the second rotating shaft 133 is equal to the diameter d6 of the cross section of the shaft hole 310, so that the first rotating shaft 131 and the second rotating shaft 133 are in contact with the inner wall of the shaft hole 310 at least at one point, thereby reducing the virtual position, reducing the jitter of the wind sweeping blade 100 during rotation, and reducing the noise.

[0057] Please combine again Figure 1 and Figure 2 In a preferred embodiment of the present invention, the wind sweeping blade 100 includes a mounting post 150, and the mounting post 150 is suitable for being mounted in a mounting hole 350 of the wind guide frame 300. Preferably, the wind sweeping blade 100 includes two mounting posts 150, and the two mounting posts 150 are respectively located at both ends of the wind sweeping blade 100, and the wind guide frame 300 is provided with two mounting holes 350, and the two mounting posts 150 are respectively mounted in the two mounting holes 350.

[0058] Preferably, the cross-section of the mounting post 150 and the cross-section of the mounting hole 350 are both circular, and the radius of the mounting post 150 is smaller than the radius of the corresponding mounting hole 350. The central axis of the mounting post 150 and the central axis of the mounting hole 350 both coincide with the central axis 16 of the shaft hole 310.

[0059] It can be understood that during the rotation of the wind sweeping blade 100 , the mounting post 150 rotates in the mounting hole 350 , and there is a gap between the mounting post 150 and the mounting hole 350 , thereby reducing the resistance during the rotation.

[0060] like Figure 2 As shown, in a preferred embodiment of the present invention, the wind sweeping blade 100 further includes a fourth rotating shaft 171 and a fifth rotating shaft 173. The fourth rotating shaft 171, the fifth rotating shaft 173 and the first rotating shaft 131, the second rotating shaft 133 and the third rotating shaft 135 are arranged on the same side of the wind sweeping blade 100. The fourth rotating shaft 171 is farther from the wind sweeping blade 100 than the first rotating shaft 131, the second rotating shaft 133 and the third rotating shaft 135, and the fifth rotating shaft 173 is farther from the wind sweeping blade 100 than the first rotating shaft 131, the second rotating shaft 133 and the third rotating shaft 135. The fourth rotating shaft 171 and the fifth rotating shaft 173 are respectively arranged at positions of the wind sweeping blade 100 close to both ends of the wind sweeping blade 100, and the first rotating shaft 131, the second rotating shaft 133 and the third rotating shaft 135 are arranged between the fourth rotating shaft 171 and the fifth rotating shaft 173.

[0061] like Figure 1As shown, two rotating holes 370 are provided on the air guide frame 300. The cross sections of the two rotating holes 370 are both circular, the radii of the two rotating holes 370 are equal, and the central axes of the two rotating holes 370 coincide. The central axis of the rotating hole 370 is parallel to the central axis 16 of the shaft hole 310. The fourth rotating shaft 171 and the fifth rotating shaft 173 are respectively provided in the two rotating holes 370, and the fourth rotating shaft 171 and the fifth rotating shaft 173 are both suitable for rotating in the rotating holes 370.

[0062] In a preferred embodiment of the present invention, the central axis of the fourth rotating shaft 171 and the central axis of the fifth rotating shaft 173 are both parallel to the central axis of the rotating hole 370, the central axis of the fourth rotating shaft 171 and the central axis of the fifth rotating shaft 173 are axially symmetrical about the central axis of the rotating hole 370, and the sum of the radius of the cross section of the fourth rotating shaft 171 plus the radius of the cross section of the fifth rotating shaft 173 plus the distance between the central axis of the fourth rotating shaft 171 and the central axis of the fifth rotating shaft 173 is equal to the diameter of the rotating hole 370.

[0063] It can be understood that during the rotation of the fourth rotating shaft 171 and the fifth rotating shaft 173 in the rotating hole, the contact area between the fourth rotating shaft 171 and the fifth rotating shaft 173 and the inner side wall of the rotating hole 370 is small, and the fourth rotating shaft 171 and the fifth rotating shaft 173 have small resistance during the rotation process, and the rotation is relatively smooth. The fourth rotating shaft 171 and the fifth rotating shaft 173 are both in contact with the inner side wall of the rotating hole 370 at least at one point, which reduces the virtual position, reduces the shaking of the wind sweeping blade 100 during the rotation process, and reduces the noise.

[0064] It can be understood that during the rotation of the wind sweeping blade 100, the motor (not shown) of the wind guide frame 300 drives the rotating hole 370 to move, and the rotating hole 370 rotates around the central axis l6 of the shaft hole 310. At the same time, the first rotating shaft 131, the second rotating shaft 133 and the third rotating shaft 135 all rotate around the central axis l6 of the shaft hole 310, and the fourth rotating shaft 171 and the fifth rotating shaft 173 rotate with the rotating hole 370 around the central axis l6 of the shaft hole 310, thereby realizing the rotation of the wind sweeping blade 100.

[0065] The embodiment of the present invention further provides an air conditioner, comprising the wind sweeping blade 100 provided by the embodiment of the present invention.

[0066] Another embodiment of the present invention provides an air guide frame for pivotally connecting with the wind sweeping blade 700. The air guide frame includes a first rotating shaft 531 and a second rotating shaft 533. Figure 7A plurality of shaft holes 730 distributed along the vertical direction are provided on the wind sweeping blade 700, and the first rotating shaft 531 and the second rotating shaft 533 are respectively rotatably provided in the corresponding shaft holes 730, and the shaft hole 730 rotates around the first rotating shaft 531 and the second rotating shaft 533 with the central axis L6 of the shaft hole 730 as the axis to realize the rotation of the wind sweeping blade 700 with the central axis L6 of the shaft hole 730 as the axis.

[0067] In the embodiment of the present invention, a plurality of shaft holes 730 are provided on the wind sweeping blade 700, and the plurality of shaft holes 730 are all provided on the same side of the wind sweeping blade 700, and the cross section of each shaft hole 730 is circular, and the cross section of each shaft hole 730 has the same radius, and the central axis L6 of each shaft hole 730 coincides, and each first rotating shaft 531 is provided in a shaft hole 730, and each second rotating shaft 533 is provided in a shaft hole 730. Figure 8 In the embodiment of the present invention, an axial hole wall 730a is disposed outside the axial hole 730, and the axial hole wall 730a encloses the axial hole 730. Preferably, the axial hole wall 730a is in the shape of two-thirds of a circular ring, and the axial hole wall 730a is provided with a notch 730b in the shape of one-third of a circular ring. It can be understood that the first rotating shaft 531 and the second rotating shaft 533 are installed in the axial hole 730 through the notch 730b.

[0068] Please combine Fig. 9 The first rotating shaft 531 and the second rotating shaft 533 are both eccentrically arranged, the central axis L1 of the first rotating shaft 531 is parallel to the central axis L6 of the shaft hole 730, the central axis L2 of the second rotating shaft 533 is parallel to the central axis L6 of the shaft hole 730, and the central axis L1 of the first rotating shaft 531 and the central axis L2 of the second rotating shaft 533 do not overlap.

[0069] In a preferred embodiment of the present invention, the shaft hole 730 includes a first side and a second side, the first side and the second side are arranged opposite to each other, the first rotating shaft 531 is arranged close to the first side in the initial state, and the second rotating shaft 533 is arranged close to the second side in the initial state.

[0070] In a preferred embodiment of the present invention, the air guide frame includes a third rotating shaft 535, which is arranged between the first rotating shaft 531 and the second rotating shaft 533, and the third rotating shaft 535 is rotatably arranged in the shaft hole 730, and the central axis L3 of the third rotating shaft 535 coincides with the central axis L6 of the shaft hole 730.

[0071] In a preferred embodiment of the present invention, the central axis L1 of the first rotating shaft 531, the central axis L2 of the second rotating shaft 533, and the central axis L6 of the shaft hole 710 are located in the same plane. The first rotating shaft 531, the second rotating shaft 533, and the third rotating shaft 535 are all cylindrical, and preferably, the radius R1 of the cross section of the first rotating shaft 531, the radius R2 of the cross section of the second rotating shaft 533, and the radius R3 of the cross section of the third rotating shaft 535 are equal, and the central axis L1 of the first rotating shaft 531 and the central axis L2 of the second rotating shaft 533 are set to be axially symmetrical about the central axis L6 of the shaft hole 730.

[0072] It can be understood that the “cross section” is a cross section perpendicular to the central axis L1 of the first rotating shaft 531 and the central axis L2 of the second rotating shaft 533. The first rotating shaft 531 and the second rotating shaft 533 are regular cylindrical shapes, and their cross sections are circles with equal radius.

[0073] like Fig. 9 As shown, in a preferred embodiment of the present invention, the radius R1 of the cross section of the first rotating shaft 531 is smaller than the radius R6 of the cross section of the shaft hole 730, and the radius R2 of the cross section of the second rotating shaft 533 is smaller than the radius R6 of the cross section of the shaft hole 730. The sum of the radius R1 of the cross section of the first rotating shaft 531 plus the radius R2 of the cross section of the second rotating shaft 533 plus the distance M1 between the central axis L1 of the first rotating shaft 531 and the central axis L2 of the second rotating shaft 533 is equal to the diameter D6 of the cross section of the shaft hole 730, that is:

[0074] R1+R2+M1=D6.

[0075] It can be understood that the radius R1 of the cross section of the first rotating shaft 531 and the radius R2 of the cross section of the second rotating shaft 533 are both smaller than the radius R6 of the cross section of the shaft hole 730, which reduces the contact area between the first rotating shaft 531 and the second rotating shaft 533 and the inner wall of the shaft hole 730, thereby reducing the resistance of the shaft hole 730 during the rotation around the first rotating shaft 531 and the second rotating shaft 533, making the rotation of the shaft hole 730 smoother.

[0076] It can be understood that the sum of the radius R1 of the cross section of the first rotating shaft 531, the radius R2 of the cross section of the second rotating shaft 533, and the distance M1 between the center axis L1 of the first rotating shaft 531 and the center axis L2 of the second rotating shaft 533 is equal to the diameter D6 of the cross section of the shaft hole 730, so that the first rotating shaft 531 and the second rotating shaft 533 are in contact with the inner wall of the shaft hole 730 at least at one point, thereby reducing the virtual position, reducing the shaking of the wind sweeping blades during rotation, and reducing noise.

[0077] Fig. 9 Please combine again Figure 7In a preferred embodiment of the present invention, the air guide frame includes a mounting hole, and the wind sweeping blade 700 is correspondingly provided with a mounting post 750, and the mounting post 750 is suitable for being installed in the mounting hole. Preferably, the air guide frame includes two mounting holes, and the wind sweeping blade 700 is correspondingly provided with two mounting posts 750, and the mounting posts 750 are respectively located at both ends of the wind sweeping blade 700, and the two mounting posts 750 are respectively installed in the two mounting holes.

[0078] Preferably, the cross section of the mounting post 750 and the cross section of the mounting hole are both circular, and the radius of the mounting post 750 is smaller than the radius of the corresponding mounting hole. The central axis of the mounting post 750 and the central axis of the mounting hole both coincide with the central axis L6 of the shaft hole 730.

[0079] It can be understood that during the rotation of the wind sweeping blade, the mounting post 750 rotates in the mounting hole, and there is a gap between the mounting post 750 and the mounting hole, which reduces the resistance during the rotation process.

[0080] In a preferred embodiment of the present invention, the air guide frame further includes a fourth rotating shaft and a fifth rotating shaft. Figure 7 As shown, the wind sweeping blade 700 is correspondingly provided with two rotating holes 770, and the fourth rotating shaft and the fifth rotating shaft are respectively provided in the two rotating holes 770. The rotating hole 770 is suitable for rotating around the fourth rotating shaft and the fifth rotating shaft with the central axis of the rotating hole 770 as the axis.

[0081] The two rotating holes 770 and the shaft hole 730 are both located on the same side of the wind sweeping blade 700, and the rotating hole 770 is farther away from the wind sweeping blade 700 than the shaft hole 730. The two rotating holes 770 are respectively arranged at positions close to both ends of the wind sweeping blade 700, and the plurality of shaft holes 730 are all located between the two rotating holes 770. The cross sections of the two rotating holes 770 are both circular, the radii of the two rotating holes 770 are equal, and the central axes of the two rotating holes 770 coincide. The central axis of the rotating hole 770 is parallel to the central axis of the shaft hole 730.

[0082] In a preferred embodiment of the present invention, the central axis of the fourth rotating shaft and the central axis of the fifth rotating shaft are both parallel to the central axis of the rotating hole 770, the central axis of the fourth rotating shaft and the central axis of the fifth rotating shaft are axially symmetrical about the central axis of the rotating hole 770, and the sum of the radius of the cross section of the fourth rotating shaft plus the radius of the cross section of the fifth rotating shaft plus the distance between the central axis of the fourth rotating shaft and the central axis of the fifth rotating shaft is equal to the diameter of the rotating hole 770.

[0083] It can be understood that during the rotation of the rotating hole 770, the contact area between the fourth rotating shaft and the fifth rotating shaft and the inner side wall of the rotating hole 770 is small, the rotating hole 770 has a small resistance during the rotation, and the rotation is smoother. The fourth rotating shaft and the fifth rotating shaft are both in contact with the inner side wall of the rotating hole 770 at least at one point, which reduces the virtual position, reduces the shaking of the wind sweeping blade during the rotation, and reduces the noise.

[0084] It can be understood that during the rotation of the wind sweeping blade 700, the motor of the wind guide frame drives the fourth rotating shaft and the fifth rotating shaft to move, and the rotating hole 770 rotates around the central axis L6 of the shaft hole 730. At the same time, the shaft hole 730 rotates around the first rotating shaft 531 and the second rotating shaft 533 with the central axis L6 of the shaft hole 730 as the axis. Thus, the rotation of the wind sweeping blade 700 is realized.

[0085] Another embodiment of the present invention further provides an air conditioner, comprising the air guide frame provided by another embodiment of the present invention.

[0086] The wind sweeping blade and wind guide frame provided in the embodiment of the present invention, through the eccentric setting of the first rotating shaft and the second rotating shaft, make the first rotating shaft and the second rotating shaft fit with the inner wall of the shaft hole, reduce the virtual position, thereby reducing the jitter of the blade during rotation and reducing noise.

[0087] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
