Unlike the present embodiment, a single insertion space may be formed in the first insertion space 721a and the second insertion space 722a. When one insertion space is formed, the first fixing block and the second fixing block are inserted into one insertion space, and thus there may be a gap.

Since the wire guider 700 is a structure for supporting the wire, it is necessary to minimize play or shaking. When the wire is supported, if the guider 750 is shaken, not only an operating noise is generated, but also a larger shake is generated in the suction grill 320 supported by the wire.

The first insertion space 721a and the second insertion space 722a are formed in a horizontal direction. The assembly block body 740 is opened only on one side, and the other side is closed.

Since the first separation prevention protrusion 743 formed on the assembly block in this embodiment is formed to surround the outer surface of the guider 750, the wire is prevented from being separated between the guider body 752 and the assembly block 720. can

The gap between the first separation prevention protrusion 743 and the outer surface 752a of the guider 750 is formed smaller than the diameter of the wire, through which the wire is separated from the wire groove 754 and is separated out of the guider 750 can block it The wire installed in the guider groove 754 is positioned between the second guider installation wall 742b and the wire groove 754 .

At least a portion of the first separation preventing protrusion 743 may have a center of curvature at the center of rotation of the guider shaft 755 . The first separation prevention protrusion 743 is located above the rotation center of the guider shaft 755 .

When the guider shaft 755 is inserted into the guide shaft grooves 744 and 746 , the outer surface 752a of the guider body 752 may interfere with the first separation preventing protrusion 743 . When the guider shaft 755 is inserted into the guide shaft grooves 744 and 746 , the guider body 752 is assembled with the separation preventing protrusion 743 in the form of an interference fit. After the guider shaft 755 is assembled, the outer surface 752a of the guider body 752 and the separation prevention protrusion 743 are maintained spaced apart by a predetermined distance.

If the operator does not intentionally separate the guider 750 through this structure, the guider shaft 755 is caught by the separation prevention protrusion 743 and is not separated.

The first guide shaft groove 744 and the second guide shaft groove 746 are symmetrical with respect to the guider installation space 742 .

The first guide shaft groove 744 and the second guide shaft groove 746 are formed to be concave downward from the upper surface of the assembly block body 740 .

Since the shape of the second guide shaft groove 746 is symmetrical with the first guide shaft groove 744, the first guide shaft groove 744 will be described as an example.

The guide shaft grooves 744 and 746 include a first shaft wall 744a, a second shaft wall 744b, and a third shaft wall 744c.

The first axial wall 744a and the third axial wall 744c are formed parallel to each other. The guider shaft 755 of the guider 750 is inserted between the first shaft wall 744a and the third shaft wall 744c. A distance between the first shaft wall 744a and the third shaft wall 744c is formed to be wider than the diameter of the guider shaft 755 . The guider shaft 755 may rotate between the first shaft wall 744a and the third shaft wall 744c.

Unlike the present embodiment, only one of the 2-1 th separation prevention protrusion 747a and the 2-2 separation prevention protrusion 747c may be disposed.

The gap between the 2-1th separation preventing protrusion 747a or the 2-2nd separation preventing protrusion 747c is formed to be smaller than the diameter of the guider shaft 755 . The 2-1 th separation prevention protrusion 747a and the 2-2 separation prevention protrusion 747c are located above the rotation center of the guider shaft 755 .

The 2-1 th separation prevention protrusion 747a and the 2-2 separation prevention protrusion 747c have a shape surrounding a portion of the outer side of the guider shaft 755 . The arrangement direction of the 2-1th separation preventing protrusion 747a and the 2-2nd separation preventing protrusion 747c intersects the longitudinal direction of the guider shaft 755 .

The first separation preventing protrusion 743 and the second separation preventing protrusion 747 not only prevent the guider from being separated from the assembly block 720 , but also suppress vertical movement of the guider 750 .

Either a permanent magnet 318 or a magnetic force fixing part 328 may be disposed on the front body 310, and the magnetic force fixing part 328 or a permanent magnet ( 318) may be disposed.

The permanent magnet 318 and the magnetic force fixing part 328 are located above each of the grill corner parts 327 and are hidden by each of the grill corner parts 327 . Since the permanent magnet 318 and the magnetic force fixing part 328 are positioned outside each corner of the suction grill 320, the separation between the suction grill 320 and the front body 310 can be minimized.

When the suction grill 320 and the front body 310 are spaced apart, there is a problem that the internal pressure of the suction passage 103 is lowered.

Hereinafter, an operation process when the suction grill is raised or lowered according to an embodiment of the present invention will be described in detail.

First, the installation state of the suction grill 320 will be described in more detail.

The suction grill 320 may be lowered for cleaning the filter or repairing the interior of the indoor unit. The suction grill 320 is supported by four wires 511, 512, 521, 522, and the load of the suction grill 320 is all four wires 511, 512, 521, 522. applied by

The suction grill 320 maintains a state in close contact with the front body 9310 by the four wires 511, 512, 521 and 522. That is, a separate coupling structure for supporting the suction grill 320 and the front body 310 is not disposed.

Therefore, there is no need for the user to disassemble the suction grill 320 and the front body 310 by standing on a structure such as a chair in order to separate the suction grill 320 . That is, as soon as the four wires 511 , 512 , 521 , 522 are released by the operation of the elevator 500 , the suction panel 320 descends downward.

In addition, since the suction grill 320 is supported only by each wire 511, 512, 521, 522, each wire 511, 512, 521, 522 always forms a taut tension. When the suction grill 320 is supported on another structure, some of the wires 511, 512, 521, and 522 may form a loose state, and the elevator 500 may cause each wire 511, 512 ) 521 and 522 cannot be precisely controlled.

Since each wire 511 , 512 , 521 , 522 according to the present embodiment always supports the load of the suction grill 320 , the entire length released to the outside of the elevator 500 always maintains a taut state.

The first wire fixing part 329-1, the second wire fixing part 329-2, the third wire fixing part 329-3, and the fourth wire fixing part 329-4 are of the suction panel 320. located on each corner side.

Since each of the four wire fixing parts is pulled upward by each wire to be in close contact with the front body 310, the edge of the suction grill 320 can be closely attached to the front body 310, and the sagging of the suction grill 320 can be reduced. can be minimized

Since each wire guider 701, 702, 703, 704 is arranged for the four wires 511, 512, 521, 522, each wire 511, 512, 521, 522 ) to prevent sagging.

A load applied to each wire 511 , 512 , 521 , 522 may be partially distributed to each wire guider 701 , 702 , 703 , 704 . In addition, since each wire 511 , 512 , 521 , 522 moves only along the wire groove 754 arranged in the vertical direction, each wire 511 , 512 , 521 , 522 is horizontal. It is possible to suppress the movement, thereby minimizing the shaking of the suction grill 320.

Next, a descending process of the suction grill 320 will be described.

When a user inputs an operation signal through a wireless remote control or a wired remote control while the suction grill 320 is mounted on the cover panel 300, the control unit determines the input operation signal and lowers the suction grill 320 .

When the suction grill 320 is lowered, the user can adjust the descending length of the suction grill 320 . In this embodiment, the suction grill 320 may be differentially lowered to 1m, 2m, 3m, 4.5m.

The control unit operates the first unit 510 and the second unit 520 simultaneously by determining the input operation signal, and the drum motor 540 disposed in the first unit 510 and the second unit 520 . determines the amount of rotation of

When each drum motor 540 of the first unit 510 and the second unit 520 is operated simultaneously, the suction grill 320 is tilted only when the rotation speed and rotation speed of each drum motor 540 are matched. loss can be prevented. For this purpose, it is preferable to synchronize each drum motor 540 of the first unit 510 and the second unit 520 .

In the present embodiment, when each drum motor 540 rotates each drum 530 in a first direction (for example, counterclockwise), the suction grill 320 is lowered. Conversely, when each drum motor 540 rotates each drum 530 in a second direction (eg, clockwise) opposite to the first direction, the suction grill 320 is raised.

And when each drum motor 540 rotates each drum 530 , the rotation amount sensing device 600 disposed in the first unit 510 and the second unit 520 detects the rotation sensing factor 601 . By sensing at least one of the rotation amount or the rotation speed of the drum 530 is sensed.

The control unit monitors the data sensed by the rotation amount sensing device 600 and determines whether each drum 530 rotates at the same speed.

When the step difference between the both sides by the first unit 510 and the second unit 520 is different, the counting number of the rotation detection factor 601 may be corrected in the stationary state to correct the step difference. In this embodiment, the counting number of the rotation detection factor 601 is corrected up to three times, and the elevator 500 is driven.

And the control unit monitors the lowering or raising/lowering process of the suction grill 320 by the elevator 500 through the rotation amount sensing device 600 .

When the rotation of any one of the drums 530 is stopped in the ascending or descending process, each drum motor 540 is stopped immediately to block the possibility of inclination or falling of the suction grill 320 .

By the operation of each drum motor 540 , the four wires 511 , 512 , 521 , 522 are simultaneously unwound from each drum 530 . Each wire 511 , 512 , 521 , 522 passes through a fourth roller 554 , a third roller 553 , a second roller 552 , and a first roller 551 . Each wire 511 , 512 , 521 , 522 extending in the horizontal direction from each unit case 590 is turned toward the ground from the guider 750 located in the horizontal direction of each unit case 590 . .

Each of the wires 511 , 512 , 521 , and 522 may be vertically moved downward of the guider 750 while being supported on the upper surface of each guider 750 . Through this process, the other ends of each wire 511 , 512 , 521 , 522 fixed to the wire fixing part 329 of the suction grill 320 are simultaneously lowered downward.

Each wire fixing part 329 is located below each guider 750, and each wire 511, 512, 521, 522 extends in the vertical direction.

That is, since the wire fixing part 329 is disposed below the guider 750 for supporting the wire, shaking is minimized in the process of moving each wire 511 , 512 , 521 , 522 up and down. In addition, since each wire 511, 512, 521, 522 is supported by each of the four guiders 750, the load can be evenly distributed, and the load applied to the rollers of each roller box can be minimized. .

In addition, since the guider 750 and the roller box 550 are fixed structures, the wire is not shaken while being supported by the guider 750 and the first roller 551 .

Since only the wire fixing part 329 is a structure in which shaking can occur in the process of raising or lowering the suction grill 320, and the wire fixing part 329 is disposed on the lower side of the guider 750, the guider 750 and The wire length between the wire fixing parts 329 is minimized.

That is, since the guider 750 and the wire fixing part 329 are arranged in the vertical direction, the length of the wire unwound during the lowering of the suction grill 320 is minimized. When the suction grill is lowered, if the wires are arranged diagonally, a longer length of wire must be unwound than in the vertical direction.

Next, the elevating process of the elevator 500 will be described in more detail.

In a state in which the suction grill 320 is lowered, the control unit may raise the suction grill 320 to its original position by receiving a user's manipulation signal.

The control unit rotates each drum 530 of the first unit 510 and the second unit 520 clockwise to return the suction grill 320 to the initial position.

The control unit raises the suction grill 320 to a horizontal state by maintaining the same rotation amount and rotation speed of each drum 530 .

When the suction grill 320 is raised and lowered, the wire fixing part 329 is moved vertically upward, and the end of each wire is also moved from the lower side to the upper side.

By the rotation of the drum 530, the 1-1 wire 511 and 1-2 wire 512 of the first unit 510 and the 2-1 wire 521 of the second unit 520 and The 2-2nd wire 522 is wound around each drum 530 at the same time.

When the drum 530 of the first unit 510 rotates, the 1-1 wire 511 and the 1-2 wire 512 are connected to the first zone 531 and the second zone ( 532) while being aligned in the horizontal direction.

The 1-1 wire 511 is changed to a horizontal direction after passing through the guider 750 in the vertical direction, the first roller 551, the second roller 552, the third roller 553 and the third After passing through the 4 rollers 554, it is wound around the outer peripheral surface of the drum body 535 of the first section 531. After the 1-1 wire 511 is wound in one row on the outer peripheral surface of the drum body 535, it is wound while forming a layer again over the 1-1 wire 511 wound in one row.

After passing through the guider 750 in the vertical direction, the first and second wires 512 are changed to a horizontal direction, and a first roller 561, a second roller 562, a third roller 563 and a third 4 After passing through the roller 564, it is wound around the outer peripheral surface of the drum body 535 of the second section 532.

Meanwhile, in the second unit 520 , which is rotated simultaneously with the first unit 510 , the 2-1 th wire 521 and the 2 nd 2nd wire 522 are wound at the same speed as the first unit 510 . .

As with the first unit 510 , when the drum 530 of the second unit 520 rotates, one end of the 2-1 th wire 521 and one end of the 2 nd 2nd wire 522 are connected to the drum ( It is wound while being aligned with the first section 531 and the second section 532 of 530 .

As in this embodiment, the suction grill 320 is connected to the 1-1 wire 511, 1-2 wire 512, 2-1 wire 521 and 2-2 wire 522. supported by 4 points.
