FIELD OF THE INVENTION The present invention relates to an air conditioner having the function of automatically cleaning an air filter provided in a helium suction port of an indoor unit. BACKGROUND OF THE INVENTION In an indoor unit of a conventional air conditioner, an air filter for preventing dust from entering the inside of the body is disposed in front of the heat exchanger, and the air filter is detachably mounted to the filter frame to remove Adhesive dust. The filter device thus constructed not only requires frequent maintenance, but also until the pre-maintenance period. (4) The gas is shouted and gradually becomes dusty. As a result, the air volume passing through the hot parent converter is reduced, and the air force is reduced, resulting in electric power. Increase. Therefore, in order to reduce the maintenance time of the air transition device, an air conditioner having an automatic cleaning function for the air blouse is proposed (for example, refer to Patent Document U. Another automatic cleaning function is also proposed. The air blending machine, which has the automatic cleaning of the Wei U and the wealth from the rhythm n, the dust attracting part attracts the fan to attract the dust, and attracts the duct to the dust (4) to the automatic sweeper. (Patent Document 2) For example, Japanese Patent Laid-Open Publication No. 2 GG2-340395, and the air conditioner described in Patent Document 1, due to the brush 1351498? "Monthly" 3. The daily repair (more) replacement page and the air filter rub against each other, so there is a problem that dust is attached to the brush or the brush is damaged or deformed to reduce the function. Also, after a certain period of time, It is necessary to deal with the dust collected by the brush and it is not possible to greatly reduce the maintenance time. 5 On the other hand, in the air conditioner described in Patent Document 2, it is attached to the filter. The amount of dust varies with the time and environment of the air conditioner. When the dust is not cleaned for a long time, the dust will be solidified without being difficult to attract. Therefore, when the amount of dust is too large or not cleaned for a long time, it cannot be completely cleaned. Dust • The problem of dust remaining on the air filter. 10 “The dust that has accumulated in the dust storage unit must be discarded, and it is not possible to greatly reduce the cleaning time. From this point of view, it is suitable as a fully cleanable air conditioner. The filter is a cleaning method that sucks the dust from the filter by the suction fan from the small dust suction portion of the filter in the two directions, and discharges the dust to the outside by the suction duct and the exhaust duct. 15 good.

However, in this method, there is a problem that the dust absorbed during the cleaning is gradually deposited on the suction duct or the exhaust duct to reduce the amount of suction air, and as a result, the cleaning performance of the filter is lowered. There is also a problem that when the filter is completely cleaned, the cleaning time is increased and the air conditioning function is limited during this period, which makes the user less convenient to use. Further, the air filter of the air conditioner is generally curved, with the upper portion being horizontal and the lower portion being vertical. At this time, the amount of dust attached to the air filter is generally lower than that of the upper portion. So 'when to make the air filter 6 1351498 _ . ??? with. Japanese repair (more) replacement page - When the upper and lower parts are the same suction air volume to attract dust, there is unevenness in the suction method, and the dust on the upper part remains due to different conditions, and the lower part is the suction air volume exceeding the demand, resulting in unnecessary consumption. The topic of electricity. L invention content ϋ 5 invention reveals problems to be solved by the invention

The present invention has been made in view of the problems of the prior art, and an object thereof is to provide a dust which can be easily and efficiently removed by a user, and which can reliably and efficiently remove dust adhering to an air filter. , 10 air filter cleaning performance will not decline, and will not cost the air conditioner. In order to achieve the above object, an air conditioner according to the present invention has an indoor unit that houses a heat exchanger and a fan that blows air exchanged by the heat exchanger to a room, and the air conditioner includes a filter device. 15 is configured by a filter that removes dust from the air passing through the heat exchanger, a suction nozzle that can be driven in the first direction along the filter, and a suction device that is coupled to the suction nozzle, and the suction nozzle has a nozzle body of the opening portion and a driving belt that drives the opening portion in a second direction perpendicularly intersecting the first direction and has a suction hole, and the second direction of detecting the suction hole The position detecting means of the position changes the cleaning ability of the suction nozzle by the position of the suction hole detected by the position detecting means. The change of the cleaning ability of the suction nozzle can change the suction timing of the first direction by the position of the suction hole detected by the position detecting mechanism. Month: log repair (complex) positive replacement page

The number is changed by changing the suction amount of the suction nozzle or changing the driving speed of the suction nozzle. Further, a dust detecting means for detecting the amount of dust adhering to the filter may be provided, and the cleaning ability of the suction nozzle may be changed according to the amount of dust adhered by the dust detecting means. At this time, the cleaning capacity of the suction nozzle is changed by changing the suction amount of the suction nozzle or changing the driving speed by the dust adhesion amount detected by the dust detecting means.

Further, the present invention has a cleaning mode for moving the suction nozzle back and forth to clean the first portion of the filter, and then moving the suction hole in the second direction to cause the suction nozzle to be in the first The 1 direction moves back and forth to clean the second portion different from the first portion of the filter, and the above operation is repeated to clean all of the filters.

In the cleaning mode, it is preferable to set the cleaning from the lower side of the filter screen to the top, and when the suction nozzle reaches the end portion of the filter in the first direction, the movement of the suction nozzle and the suction hole is stopped. Solution to Problem In the cleaning mode, it is preferable to set the fan to operate at a lower speed than when the air conditioner is running, and only clean one part of the mesh, and end the cleaning mode. Further, at the end of the cleaning mode, the suction hole is moved to the next cleaning start position, and the fan is returned to the air-conditioning operation. Further, the filtering device may have a suction duct that connects the suction nozzle and the suction device, and further has a suction duct dust discharge mode, and the suction 8 1351498 buckle. Hey. Daily repair) Positive replacement page The duct dust discharge mode is such that the suction air volume in the suction duct is larger than in the sweep mode. The filtering device may further have an exhaust duct connected to the suction device, and further have an exhaust duct dust discharging mode, wherein the exhaust duct dust discharging mode is such that the exhaust air volume in the exhaust duct is higher than the suction duct dust discharging mode. When the 5 is increased. In this case, it is preferable to change the number of rotations of the suction fan when the suction fan cleaning mode of the suction device, the suction duct dust discharge mode, or the exhaust duct dust discharge mode is changed in accordance with the length of the exhaust duct. Advantageous Effects of Invention The present invention has the following effects, and thus can exhibit the effects described below.

Since the cleaning ability of the suction nozzle can be changed according to the position of the suction hole detected by the position detecting mechanism, the suction nozzle can be driven back and forth only by the upper portion of the dust adhesion amount, and the number of suctions can be increased, thereby preventing 15 dust. Residual. Further, the same effect can be obtained by changing the suction amount of the suction nozzle or changing the driving speed. Further, a dust detecting means for detecting the amount of dust adhering to the filter is provided, and when the suction amount or the driving speed of the suction nozzle is changed according to the amount of dust adhered by the dust detecting means, the dust of the filter 20 can be reduced as much as possible. The amount of time required to shorten the cleaning of the filter can suppress the power consumption. Further, when the cleaning mode is set, the cleaning mode is repeated when the filter is cleaned, the suction nozzle is moved back and forth in the first direction, and then the suction hole is moved in the second direction, thereby changing the suction hole. Bit 9 1351498 Office? The month-repairing (more) replacement page-_ is similarly 'the operation of moving the suction nozzle back and forth in the first direction several times' to clean all of the filter nets, so it is not completely in the outward movement of the suction nozzle The attracted and residual dust can be attracted again during the return movement, and the residual dust can be prevented. Further, since the attracted dust is discharged from the exhaust duct 5 to the outside, the time for the user to clean the filter can be saved as much as possible. In particular, when there is a large amount of dust adhesion or when the filter is not cleaned for a long time, it is possible to repeatedly perform the back and forth movement in the first direction several times, and to remove dust that has not been completely removed in one roundback operation, and to prevent dust. stay. In particular, when there is a large amount of dust, there is also a 1G a angstrom deposited in the vertical portion of the filter. When the suction nozzle is pulled down and is in the cleaning mode, (4) the lower side of the filter is cleaned in order from the upper side, so the upper side of the suction hole The dust that has fallen off is attracted from the suction hole on the lower side and the lower side of the suction hole has been cleaned, so the dust will not be dropped and will not accumulate. 15 20 ; The dust of the filter is large, and the dust that cannot be completely extracted from the suction hole is dropped to the left or right end of the hole and the hole is left.

When the wind 4 is down, it is impossible to fully replenish the original air conditioning function. Moreover, due to cleaning over 10 1351498? The monthly repair (more) is replacing the page ... j; all the nets need to be "long time (for example, 30 points), for the user, the air conditioning function is limited during this period. Therefore, by limiting one cleaning position to one part of the filter, the cleaning time can be shortened, and the user's usability can be improved. 5 Also, when the filter cleaning is finished, the suction hole is moved to the next time.

The sweep start position is not required to move the suction hole to the cleaning start position at the start of the next cleaning, and the next filter cleaning time can be shortened, thereby improving the user's usability. The fan that is limited to the low speed operation during the cleaning period is restored to the high speed operation, and after the filter cleaning is completed, the air 10 reconciliation function can be quickly recovered, thereby improving the user's usability.

When the suction duct dust discharge mode in which the suction air volume in the suction duct is increased compared to the sweep mode is set, the air flow velocity in the suction duct can be accelerated, and during the sweep mode, the dust accumulated in the suction duct can be blown up. , to prevent the cleaning performance from degrading. Furthermore, when the exhaust duct dust discharge mode in which the exhaust gas volume in the exhaust duct is increased compared to the suction duct dust discharge mode is set, the air flow velocity in the exhaust duct can be accelerated, and in the sweep mode or attraction. During the duct dust discharge mode, the dust accumulated in the exhaust duct can be blown up to prevent the cleaning performance from deteriorating. Further, the length of the exhaust duct is different depending on the state of the air conditioner installation place. When the length is increased, the amount of suction air during the cleaning mode is lowered, and the suction performance is lowered. Therefore, depending on the length of the exhaust duct when the air conditioner is installed, the number of revolutions of the suction fan in the cleaning mode can be changed, and the cleaning performance of the filter can be maintained appropriately. Similarly, depending on the length of the exhaust duct, change the suction duct dust discharge mode 11 1351498? Month day repair (to) is replacing page

In the case of the number of revolutions of the suction fan in the exhaust duct dust discharge mode, the suction duct discharge performance or the exhaust duct dust discharge performance of the length of the exhaust duct can be prevented, and the cleaning performance of the filter can be maintained appropriately.

Embodiment 1 The best mode for carrying out the invention is as follows. The first embodiment of the present invention is a cross-sectional view of an indoor unit of an air conditioner according to the present invention. The indoor unit body 2 houses a heat exchanger 4 and a heat exchanger 4 therein. After the indoor air is taken in, the air exchanged by the heat exchanger 4 is blown out to the fan 6 in the room and the filter device 8 disposed on the heat exchanger 4, and the fan 6 is moved 15 from the front of the body 2 to The plurality of suction ports formed above absorb air, and the dust floating in the air is removed by a filtering device 8 disposed between the suction port and the heat exchanger 4. Also, as shown in Fig. 2, the heat passing through the heat exchanger 4 is removed. It The dust filter device 8 has a filter frame 1A, a filter screen 12 for holding the filter frame, and a suction nozzle 14 slidable along the surface of the filter 12. The filter frame 10, the filter 12, and the like are bent. The upper portion constitutes a horizontal direction and the lower portion constitutes a vertical direction. The suction nozzle 14 is disposed on the filter screen 12 by a pair of guide rails l〇a disposed at the upper and lower ends of the filter frame 10, and has a small gap with the filter screen 12 to smoothly move left and right. The dust is sucked from the suction nozzle 14. Further, the suction nozzle 14 is connected to one end of the suction duct 16 and the other end of the suction duct 16 is coupled to the suction device 18, in accordance with the specification of the specification of the publication No. 94,136, 172. The suction device 18 is a fan motor that can change the amount of suction and is adjustable in number of revolutions. The suction duct 16 forms a bendable duct, and does not interfere with the movement of the suction nozzle 14. Further, the suction device 18 is connected to the fifth row. The air duct 20 is guided to the outside, and the dust adhering to the filter screen 12 and sucked by the suction nozzle 14 is discharged through the suction duct 16, the suction device 18, and the exhaust duct 20. Next, referring to Figs. 3 to 5, the suction nozzle 14 will be described. ® Fig. 3 is a view of the suction nozzle 14 viewed obliquely from above. As shown in Fig. 3, the suction nozzle 14 is attracted as shown. The nozzle body 22 of the wind flow passage is formed by a belt 24 having a width of 20 mm surrounding the nozzle body 22. The body 22 is formed on the surface of the filter 12 to have a length of 320 mm (corresponding to the longitudinal length of the filter 12). The slit-shaped nozzle opening portion 22a has a width of 3 mm. On the other hand, the belt 24 is formed into an outer circumference of the annular 'winding nozzle body 22 to cover the nozzle opening portion 22a. The belt 24 is provided with a length of 80 mm (the longitudinal direction of the filter screen 12) The suction hole 24a of 1/4 of the length and 2 mm of the width is provided with an indication portion 26 on the side of the suction hole 24a to detect the position thereof. The suction hole sensor 28 is provided inside the suction nozzle 14 and brought into contact with the indication portion 26 so that the position of the indication portion 26 can be detected frequently, and the position of the suction hole 24a is detected. The driving holes 30 are disposed at equal intervals of the two ends 20 of the driving belt 24, such as the motion picture film. The gears 34 of the stepping motor 32 fixed on the nozzle body 22 are engaged by the driving holes 3, so that the driving belt 24 can be Drive freely in the up and down direction. Fig. 4 is a view showing a nozzle body 22 and a belt μ in Fig. 3, respectively, and Fig. 5 is a cross-sectional view of the suction nozzle 14 (a wearing diagram of ν·ν along the line of Fig. 3). 14 1351498 ~ ' ?萆? In the suction nozzle 14 thus constructed, as the other structure for driving the belt, it is also conceivable to drive the belt 24 with a rubber roller or the like without using the gear 34'. Further, in the embodiment of the present invention, the drive belt 24 is formed in a ring shape in order to reduce the size of the apparatus, and a method of winding a belt such as a reel is also provided. In the present embodiment, the filter 12 is completely sucked and cleaned by the suction nozzle 14 having the above configuration. Therefore, the specific operation will be described using Figs. 2, 6 and 8 .

Fig. 6 is a view showing the position of the suction hole 24a corresponding to the cleaning range A, B, C, and D of the filter screen 12 shown in Fig. 2 (the suction nozzle 14 10 is viewed from the back side). Further, the actual suction nozzle 14 has a structure that is bent along the filter screen 12 as shown in Fig. 2, and is shown in a state in which the suction nozzle is straightened in Fig. 6 for convenience of viewing. First, when the A range of the filter screen 12 of Fig. 2 is sucked, the drive belt 24' is driven to fix the suction hole 24a to the position A as shown in Fig. 6(a). In this state, the suction nozzle 14 is driven by the right end of the filter screen 12 to the left end while sucking, and the horizontal direction of the cleaning filter 12 can be attracted. Next, the belt 24 is driven to the suction cleaning in the range of B of the filter 12 of Fig. 2, and the suction hole 24a is fixed to the position of 2 〇 B shown in Fig. 6(b). Similarly, in this state, the suction nozzle 14 is driven to the right end by the left end of the filter 12 while sucking, and this time, the horizontal direction of the B of the filter 12 of Fig. 2 is sucked and cleaned. Similarly, it is also possible to attract the range of C and D of the filter 12 of Fig. 2 to be cleaned. Since the range of C and D of the filter 12 of Fig. 2 is set in the horizontal direction, the amount of dust adhesion is larger than the range of A and B, 15 ? Month 3 Yang Xiu (more) is replacing the page and needs more. And 引量. Fig. 7 and Fig. 8 show this by arrows. And the order of the monthly sweep, the A and B ranges of the filter 12 of Fig. 2 are as shown in Fig. 7, and only the suction nozzle I4 is horizontally moved in only one direction to perform the sweeping horizontal direction. The range of C and D of the filter 12 of Fig. 2 is such that the suction nozzle is horizontally moved (moved back and forth) in the two directions as shown in Fig. 8 to perform one row in the horizontal direction of the grooming. By performing the horizontal sweeping attraction action, the filter 12 can be cleaned approximately uniformly. Further, as shown in Fig. 2, restriction switches 36, 38' are provided on both sides of the filter frame 1'', and the suction nozzles are moved back and forth in the horizontal direction by the suction nozzles abutting the restriction switches 36, 38. The details of the second embodiment will be described later. According to the present embodiment, the position of the suction hole 24a can be detected. When the position of the suction hole 24a is located at the upper portion of the filter screen 12, the suction nozzle "drives back and forth and increases the number of suctions, thereby preventing dust from remaining. The position of the suction hole 24a detected by the suction hole sensor 28 of the detecting mechanism changes the cleaning ability of the suction nozzle 14, and the filter mesh can be cleaned almost uniformly. Further, the position of the suction hole 24a is located in the filter screen 12. In the upper portion, by increasing the output of the suction device 18, the amount of suction is increased, and dust is prevented from remaining. At this time, the suction nozzle 14 performs the operation shown in Fig. 7 to perform cleaning. Further, when the suction hole 24a is located When the upper portion of the filter 12 is lowered, the frequency of the horizontal direction of the suction nozzle 14 is lowered, so that the time is increased to prevent dust from remaining. Further, 'as shown in Fig. 9, 'the nozzle body 22 is provided for detecting the filter 1351498.知 月 月 月 ) 正 正 正 正 正 正 正 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 尘 尘 尘 尘 尘 尘 尘 尘 尘 尘 尘 尘 尘 尘 尘 尘After the suction hole detected by the suction hole sensor 28 is positioned in the portion, the output of the suction device 18 is locally increased, and the suction amount is increased or the driving speed of the horizontal direction of the suction nozzle is locally lowered by 5, and the suction time is increased. Therefore, it is possible to prevent the dust from remaining. That is, the cleaning ability of the suction nozzle 14 can be changed by the dust adhesion amount detected by the dust sensor 40 as the dust detecting means, and the net 12 can be cleaned almost uniformly. comprehensive.

Second Embodiment FIG. 10 and FIG. 11 show a suction nozzle 14A provided in an indoor unit of an air conditioner according to a second embodiment of the present invention, and wound around the outer circumference of the nozzle body 22 to cover the first nozzle opening 22a. The belt 24 is formed with a first suction hole 24a for sucking dust (for example, a width of 5 mm and a height of 50 mm). The first suction 24a is provided on the belt 24 and is located directly above the first nozzle opening 22a. Further, one of the predetermined lengths of the second nozzle opening portion 22b is formed on both sides of the first nozzle opening portion 22a near the upper end of the nozzle body 22, and the transmission belt 24 is formed on the both sides of the first suction hole 24a by a predetermined length. The second suction hole 24b. The air conditioner of the present embodiment has a cleaning mode for sucking dust adhering to the filter screen 12, a suction duct dust discharge mode for discharging the dust remaining in the suction duct 16, and a dust for remaining in the exhaust duct 20. In the exhaust mode, the exhaust duct discharge mode is such that the second suction hole 24b is blocked by the nozzle body 22 in the cleaning mode, and the second nozzle opening 22b is provided in the suction duct dust discharge mode and the exhaust duct dust discharge mode. Connected to the second suction hole 24b, and 17 1351498? Month <3 〇日修 (more) is replacing the purchase ----------- to increase the air volume. Since the other configuration is the same as that of the first embodiment described above, the description thereof will be omitted. The operator's operation in the case of performing the overall cleaning of the filter unit 12 of the indoor unit 5 having the above configuration will be described with reference to Figs. 12 and 13'.

When the cleaning of the filter 12 is started, the cleaning mode is first selected, the fan 6 is set to the low speed operation (lower speed operation during the air conditioning operation), and the belt 24 is driven to fix the first suction hole 24a to the second figure. position. In this state, the number of revolutions of the suction fan (not shown) 10 provided in the suction device 18 is S1 (for example, 4000 rpm), and the suction nozzle 14 is moved from the right end to the left end. The left limit switch 36 detects the suction nozzle 14. When the left end is reached, the movement of the suction nozzle 14 is stopped for 5 seconds. At this 5 seconds, the dust block which is dropped by the suction nozzle 14 can be attracted. Then, the suction nozzle 14 is moved from the left end to the right end, and the right limit switch 15 38 detects that the suction nozzle 14' reaches the right end, and the range of the filter screen 12 is clear.

The sweep is over. After the suction nozzle 14 reaches the right end, the movement of the suction nozzle 4 is stopped for 5 seconds, and then the 'drive belt 24' fixes the first suction hole 24a to the position B of the filter 12 of Fig. 2 . 2〇 Thereafter, the range of B to D of the filter 12 of Fig. 2 is cleaned. Fig. 13 is a view showing the cleaning procedure of the embodiment, in which the vertical movement of the suction nozzle 14 in combination with the solid arrow and the intermittent operation from the lower side to the upper side of the first suction hole 24a of the broken arrow can prevent the vertical portion of the filter 12. The dust of (A~B position) is falling. 18 1351498 ?Cup? Month >Day Repair) is replacing the page. In addition, by attracting the dust that is not fully attracted in the journey, it can prevent the dust from remaining, and can automatically clean the filter 12 comprehensively. Moreover, since the dust of the sucking bow I can be discharged from the exhaust duct 20, the cleaning time of the transition net 12 of the user can be saved. 5 At the end of the overall cleaning of the stomach material 'net 12', the cleaning mold is finished, and the screw is switched to the suction pipe I. In the suction duct dust discharge mode, the drive transmission ▼ 24 fixes the first suction hole 24a to the position shown in Fig. 12(d). In the suction bow 1 duct dust discharge mode, since the second suction hole of the belt 24 is torn to the second nozzle opening 22b of the nozzle body 22, the suction air volume of the suction nozzle 14 is increased compared with the cleaning mode. The increased air volume will discharge the dust accumulated in the suction guide 16. Thereby, the cleaning performance of the filter can be prevented from being lowered. After the first suction hole 24a is held at the position of the suction duct dust discharge mode for one second, the suction duct dust discharge mode is terminated, and the exhaust duct dust discharge mode is shifted. In the exhaust duct dust discharge mode, the first suction y hole 24a is held at the suction duct dust discharge mode, and the number of rotations of the suction fan of the suction device 18 is increased to S2 (for example, 5000 rpm) higher than S1. The amount of wind in the exhaust duct 2 is increased. Ί0 By keeping this mode for 15 seconds, the dust accumulated in the exhaust manifold can be discharged to the outside of the house. Thereby, the cleaning performance of the filter can be prevented from being lowered. When the exhaust duct dust discharge mode is completed, the fan 6 is returned to the high speed operation, and the air blending function is restored, and the belt 24 is driven to return the first suction hole 24a; the position of the A of the net 12 is considered. 19 1351498 Made? The first replacement hole 24a has reached the cleaning start position at the start of the cleaning of the next filter 12, so that the first attraction is not required, and the first suction hole 24a has reached the cleaning start position. Since the hole 24a is moved, the cleaning time can be shortened, so that the user's usability can be improved. When the cleaning of the filter 12 is not performed for a long period of time, in the cleaning mode, in the Fig. 13, the first suction hole 24a is fixed to the position A, and the suction nozzle 14 is repeatedly reciprocated several times (for example, 2). After the second reciprocation, the first suction hole 24a is moved to the position of B, and thereafter, the position is repeated to the position D.

As a result, the portions A to D are repeatedly sucked, and when the amount of dust is large or the filter 12 is not cleaned for a long period of time, it is possible to prevent the dust adhering to the filter 12 from remaining. Further, when the entire cleaning of the filter screen 12 is performed, the air conditioner can be restricted for a long period of time. Therefore, in Fig. 13, after the position of the cleaning filter 12 is completed, the mode can be shifted to the suction duct dust discharge mode. 15 By this, the cleaning time of the filter 12 can be shortened once, and the use time can be shortened.

When sweeping the filter 12, when you want to use the air blending function, you don't have to wait for a long time. Moreover, the cleaning of the next filter 12 starts from the B position. Fig. 14 is a view showing the relationship between the suction air volume and the length of the exhaust duct 20. When the length of the exhaust duct 20 is increased, the amount of suction air is reduced, and when it exceeds a certain length, the necessary attraction for attracting dust is lowered. The amount of air is generated, and the residue of dust adhering to the filter 12 occurs. Further, the length of the exhaust duct differs depending on the place where the air conditioner is installed. Therefore, during the construction of the air conditioner, the constructor uses the remote control (not shown) to iron the length of the exhaust duct 20, and will clean the mode and draw the dust from the suction duct 20 1351498. Monthly repair (※ positive replacement

In the L: _____I mode, the number of rotations of the suction fan of the suction device 18 is changed from S1 to S3 (for example, 5000 rpm), and the number of rotations of the suction fan in the exhaust duct dust discharge mode is changed from S2 to S4 (for example, 6000 rpm). Thereby, it is possible to always ensure that the air volume is to be sucked by the construction condition of the exhaust duct 20, and the cleaning performance of the filter screen 12 can be maintained appropriately. Further, in addition to the length of the exhaust duct 20, the number of revolutions of the suction fan can be changed depending on the number of times the exhaust duct 20 is bent.

As described above, since the air conditioner of the present invention can prevent the residual dust of the filter attached to the indoor unit, and at the same time, the time for the user to clear the filter can be completely saved, so that various air conditioners can be applied.
