The guide bar 300 is composed of a pair of square pipes, one end of which is fixed to the main body 100 and the other end of which is fixed to the auxiliary body 200. More specifically, one end of the guide bar 300 is mounted on the mounting table 119a of the elevating unit 119 on the main body 100 side and the other end is mounted on the mounting plate 217 on the auxiliary main body 200 to be in a horizontal state have.

Next, the detailed structure of the cleaning head 400 will be described.

The cleaning head 400 is selectively clamped on the main body 100. When the clamping is released, the cleaning head 400 is installed to be movable along the guide bar 300 between the main body 100 and the auxiliary main body 200, Of the heat exchanger.

The cleaning head 400 includes a cleaning unit 410 and a driving unit 450.

The cleaning unit 410 has a fixing block 411 rotatably installed. The fixing block 411 is an intermediate component for rotating the cleaning unit 410 by 360 ° or for moving the cleaning unit 410 forward and backward.

Further, the cleaning unit 410 has a guide frame 412.

The guide frame 412 is installed on the fixed block 411 and is installed to be movable in the longitudinal direction of the fixed block 411.

The guide frame 412 includes a first guide panel 412a provided with a guide rail 412b and a guide rail 412b disposed to face the first guide panel 412a with a predetermined gap therebetween A first connecting plate 412e connecting the front ends of the first and second guide panels 412a and 412c and a second connecting plate 412b connecting the rear ends of the first and second guide panels 412a and 412c, And a second connection plate 412f connecting the first connection plate 412a and the second connection plate 412f.

A guide block 412g is provided on each of the guide rails 412b and 412d of the first and second guide panels 412a and 412c and both sides of the fixed block 411 are coupled to the guide block 412g . Therefore, the guide frame 412g can slide in the longitudinal direction of the fixing block 411 via the guide block 412g.

In addition, the cleaning unit 410 has a distance sensor 413.

The distance sensor 413 is provided at the tip of the guide frame 413 and rotates together with the guide frame 413 by 360 ° to sense the relative distance to the heat exchanger H in each rotation section. In other words, the distance sensor 413 measures the relative distance to the inner diameter portion of the heat exchanger H while rotating 360 degrees, and calculates the measured value.

In addition, the cleaning unit 410 has a cleaning nozzle 414.

The cleaning nozzle 414 serves to spray wash water toward the heat exchanger H while being installed adjacent to the distance sensor 413 at the tip of the guide frame 412.

Here, the cleaning nozzle 414 is vertically tilted by the tilting means 420.

12, the tilting means 420 includes a tilting motor 421 supported by the first connection plate 412e, a worm gear 422 coupled to the shaft of the tilting motor 421, And a wheel gear 423 which is coupled to the rotary shaft 414 of the nozzle 414 and installed in a state of being in a contracted state with the worm gear 422.

When the tilting motor 420 is driven, the worm gear 422 axially connected to the worm gear 422 is rotated. As the wheel gear 423 engaged with the worm gear 422 rotates, The cleaning nozzle 414 is tilted upward or downward by rotating the rotating shaft 414a.

The tilting function can be used by repeating the upward and downward tilting when necessary, and sometimes the upper and lower tilting angles can be fixed. As a result, various cleaning angles can be applied according to the height of the heat exchanger (H), thereby enabling efficient cleaning.

In addition, the cleaning unit 410 has a control unit 415.

The mounting position of the control unit 415 is not particularly limited, but the mounting position of the control unit 415 is illustrated in the elevating plate 452d to be described later in the embodiment of the present invention.

The control unit 415 calculates a correction value for correcting the distance between the cleaning nozzle 414 and the heat exchanger H to an optimum distance (setting distance) based on the distance measurement value sensed by the distance sensor 413 And controls the forward and backward distances of the guide frame 412 according to the correction values.

For example, as shown in FIG. 13, in the cleaning mode, the cleaning unit 210 rotates while correcting the tip position along the imaginary optimal distance line L indicated by the one-dot chain line at the tip thereof. In this process, since the cleaning unit 210 advances to be aligned with the optimum distance line L at the corner portion of the optimal distance line L, the cleaning unit 210 is rotationally driven while maintaining a constant volume distance from the heat exchanger H, And it is possible to evenly clean the entire portion without any portion that is not cleaned.

In addition, since the washing distance can be maintained constant, the spraying pressure of the washing water can be lowered compared to the conventional method, so that the consumption of washing water can be reduced.

On the other hand, the driving unit 450 includes a forward / backward member 451 for forward / backward movement of the cleaning unit 410; A lifting member 452 for lifting the cleaning unit 410; And a rotating member 453 for rotating the cleaning unit 410.

As shown in FIG. 14, the forward / backward member 451 includes a forward / backward motor 451a disposed at a lower portion of the cleaning unit 410 and a front / rearward motor 451a coupled to the shaft of the forward / backward motor 451a.

In addition, the cleaning head 400 includes a contamination receiver 460 installed at the upper end of the drive unit 450 to receive contaminated water after cleaning.

16, the pollution water receptacle 460 is smaller than the diameter of the installation hole of the ceiling air conditioner and larger than the diameter of the heat exchanger H, and a drainage hole 461 for discharging the polluted water is formed on the bottom surface .

The contamination receptacle 460 may be provided with a sealing member 462 made of rubber or silicone on its upper surface. When the upper end of the contaminated water receiver 460 is brought into close contact with the heat exchanger H, the sealing member 462 can prevent a gap with the heat exchanger H, thereby enhancing the sealing effect.

In addition, even if there is a protruding part of the heat exchanger H, for example, a wire, the sealing member 462 is elastically deformed and can be closely contacted with the heat exchanger H, so that the sealing effect can be maintained.

The cleaning head 400 may include a heater 470 between the driving unit 450 and the lifting bar 116 to heat the washing water supplied to the washing nozzle 414 to steam the washing water . The heater 470 is installed close to the cleaning unit 410 so that the heater 470 is discharged through the cleaning nozzle 414 of the cleaning unit 410 without heat loss, so that power consumption can be reduced.
