[Prior Art] A conventional air conditioner is disclosed in Patent Document 1. In this air conditioner, a dust collecting filter is provided at an opening-opening portion extending from a front surface of one of the indoor units to a portion of a top surface, and cleaning is provided by the filter. One of the dust cleaning devices. The cleaning device is assembled to have a side portion disposed at one of the indoor units: a fan unit, and for the fan unit, an intake duct and an exhaust duct are connected. The suction duct is configured to extend laterally at one of the front portions of the indoor unit with one of the front portions and has one of the front panels on the front of the filter so as to be movable on one of the surfaces of the filter nozzle. Figure 19 is a schematic cross-sectional view showing the fan unit as seen from one side of the fan unit. In the fan unit 2, a casing 21 houses a fan 22. The fan 22 has a bottom plate 22a coupled to a motor shaft 2 and is driven to rotate by a fan motor 24. The fan 22 is formed with a plurality of blades, wherein a plurality of blades 23 extending in a radial direction The bottom plate 22a is annularly disposed at a predetermined interval. The outer casing 21 is formed to have a circular air inflow opening 21a coaxial with the fan 22, and the cover air is inflowed into the crucible 21& Installed for the fan 22. Thereby, an intake passage 25 is formed which directs a flow of intake air to the air 143780.doc -4 - 201020483 into the bore 21a. The vanes 23 are configured to flow in relative to the air. 2U outside, and guiding the air flowing in the axial direction of one of the fans 22 through the air flowing into the crucible 21a toward the outer circumferential side of one of the radial directions of the fan 22. On one circumferential surface of the outer casing 21 Above, an air outflow port (not shown) is made open and connected to the exhaust duct. When the cleaning device is driven, the fan motor 24 is driven to rotate the fan 22' and correspondingly in the inhalation Generated in channel 25 A suction air flow sucks dust adhering to the filter through the nozzle and allows the dust to pass through the suction passage 25 as indicated by an arrow line A1, and then enters the outer casing 21 through the air inflow port 21a. The air flow blown in the outer casing 21 is guided in the outer circumferential direction as indicated by the arrow lines A2 and A3, and flows out through the air through the exhaust pipe to be discharged together with the exhaust gas. The filter is automatically cleaned, thereby increasing the usability of the air conditioner. [Patent file] JP-A-2008-75658 (pages 4-6 and 5) [Summary of the Invention] However, the above-mentioned conventional air is used. In the adjustment machine, the vanes 23 are formed such that the side edges 23a of the vanes 23 on the upstream side of one of the air streams flowing into the outer casing 21 extend in the axial direction of the fan 22. Therefore, flow into the The air flow of the outer casing 21 and guided in the outer circumferential directions as indicated by the arrow lines VIII and A3 forms substantially perpendicular to each other with the side edges 23a of the blades 23: M: M (X). & 'The dust contained in the air stream is pressed against The side edges 23a of the sheet 23 may be collected by the side edges 23 of the blades 23. Thereby, the dust tends to accumulate at the side edges 23a of the blades 23 and the blades of 143780.doc 201020483 According to Patent Document 1, a rib for supplying dust on the inner circumferential side of the blades 23 is provided. However, providing such a rib needs to be accurately maintained between such The spacing between the vanes 23 and the ribs, and correspondingly increased manufacturing difficulty. Further, a gap is formed between the ribs and the bottom plate 22a to prevent accumulation at the roots of the vanes 23. The dust on it fell. Correspondingly, one of the roots adjacent to the vanes 23 is narrowed by the presence of dust, and the dust accumulated in the roots of the vanes 23 is filled between the vanes 23 as the dust is gradually increased. The space, so the intake power is not conveniently reduced. To increase usability, it is desirable that the dust removed by the cleaning device is not discharged in any area along one of the passages in the cleaning device, and that the dust is simply discharged through the air through the fan 22. This makes the accumulation of dust at the side edges 23a and at the roots of the blades 23 a more important issue to be solved. Accordingly, the present invention has an object of providing an air conditioner which can easily reduce the amount of dust accumulated in a cleaning device. In order to achieve the above object, according to the present invention, in an air conditioner equipped with a cleaning device, the cleaning device is used to suck in and remove dust contained in the air sucked into an indoor unit from the assembly and accumulate in one of the indoor units.

Because of this configuration, an air Φ flow is generated in the suction passage as the fan rotates, whereby dust adhering to the assembly of the indoor unit flows through the suction passage via the suction dam. The air stream flowing through the suction passage then passes through the air inflow port along the plane of rotation of the fan into the outer casing. The air flow into the outer casing thus comes into contact with the side edges extending in the radial direction of the vanes and thus towards the fan: the outer circumferential side. Therefore, the air flow directed to the outer circumferential side is discharged together with the dust through the air outflow port. Further, according to the present invention, in the air conditioner of the above configuration, the ?th fan is formed to have a centrifugal fan. Due to this configuration, the flow of air flowing through the suction passage is "passed through the plane of rotation of the fan" through the air flowing in the axial direction of the fan, and then in the fan Radially expelling. Further, in accordance with the present invention, in the air conditioner of the above configuration, the side edges of the blades such as X are substantially parallel to the rotation of the fan or as the fan is The axial direction is observed from the air flowing into the crucible - increasing the distance and the inner circumferential side of the blade from the current stem | μ + μ mesh D Hai drops to the outer circumferential side of the sheet. 143780.doc 201020483 In addition: according to the present According to the invention, in the air conditioner of the above configuration, the fan system has a boss that surrounds the rotating shaft of the fan and is adjacent to the air; and the plurality of blades are formed to a projection extending to the outer edge of the air into the weir. Due to the configuration, the plane of rotation of the fan flows through the air into the bee and the air flow passes through the airflow facing the person Configured in the convex a space between the side edges of the blades on the circumferential surface and then directed to the pressing surfaces of the blades. Further in accordance with the present invention, in the air conditioner of the above configuration, the peripheral has The disc on the "face line" of the fan thus forms the air flowing into the crucible in an annular shape, and the plurality of vanes are formed so as to extend from the inner edge of the air to the air inflow into the crucible - An outer edge. The configuration is such that the air flow flowing through the "shaped air flow" through the plane of rotation of the fan passes through the side edges of the blades facing the air inflow a space between the two, and then directed to the pressing surfaces of the blades. Further in accordance with the present invention, in the air conditioner of the above configuration, the plurality of blades are in the (four) side of the line of the towel - the side surfaces of the four equal-sided blades are interconnected via an annular ring. Due to this configuration, four of the plurality of blades are reinforced by the ring and do not have between the blades and the ring and Flowing in relation to the air Further, according to the present invention, in the gas conditioner according to the present invention, the assembly includes a __transition device for collecting the floating dust sucked into the indoor unit. 143780.doc 201020483 Due to this configuration 'this filter may be cleaned automatically.

One side surface portion 25b of the air intake passage 25 is formed so as to have a diameter substantially smaller than the diameter of the air inflow port 21a at one of the air inflow ports 21a of the casing 21 axially along one of the fans 22. On the width of the small ❹ w. The side edges 23b of the vanes 23 on the side of the air inflow 埠2丨a are disposed adjacent to the air inflow port 21a along the air inflow port 21a in the air conditioner as configured above, The dust contained in the indoor unit is sucked into the indoor unit through the opening portions of the outer panel, and the dust contained therein is collected by the filter 2. The air from which dust has been removed passes through the heat exchanger 3, wherein heat is rejected from the air, and the formed air is discharged through the blower 5. In this way, the adjustment of the indoor air is performed. ^ When an instruction is assigned to drive the cleaning device, the filter motor 4, the brush motor 26 and the fan motor 24 are driven accordingly. By driving the filter drive motor 4, the filter 2 is moved in the up and down direction on the filter guide 2a. By driving the brush motor 26, the rotary brush 27 is rotated, and thus the dust collected by the filter 2 is moved up and down. By driving the fan motor 24, the fan 22 is rotated, and thus a flow of intake air is generated in the intake passage 25. 143780.doc 12 201020483 Therefore, the suction suction through the duct 25c sucks dust adhering to the filter 2 together with the air flow, and causes dust adhering to the filter 2 such as an arrow line B1 ( The front surface portion 25a passing through the suction passage 25 is shown in Fig. 1). The air flow passing through the front surface portion 25a is further passed through the side surface portion 25b having a small width w as indicated by an arrow line B2 (see FIG. 7), and then along the fan 22 as indicated by an arrow line B3. The plane of rotation flows into the outer casing 21 through the air inflow 埠 21 a. Further, the air flow is in a curved portion adjacent to the air inflow port 21a and reverses the moving direction of the air flow so as to flow into the outer casing 21 as indicated by the arrow line B4. The vanes 23 are formed such that the side edges 23b of the vanes 23 on the upstream side of the air flow flowing through the air inflow weir 21a as indicated by the arrow line B3 are configured to be parallel to the rotation The plane extends in the radial direction of the fan 22. This allows the flow of air flowing into the outer casing 21 to contact the vanes 23 at a small parental angle. Therefore, it is possible to reduce a pressing force generated when dust is contained in the air flow and the side edges 23b of the blades 23, and thus the amount of dust adhering to the blades 23 is reduced. Further, as the air flow advances in the radial direction of the fan 22, the dust collected by the side edges 23b of the blades 23 is pushed toward the outer circumferential side of the vanes 23. Further, the dust collected by the side edges 23b is urged toward the outer circumferential side of the blades 23 by centrifugal force using one of the blades 23. The amount of dust adhering to the vanes 23 may be further reduced by &'. Therefore, the process gas flowing into the outer casing 2 is guided in the outer circumferential direction of one of the fans 22, and then the air flow is passed through the air outflow port 21 e through 143780.doc -13 - 201020483 through the exhaust passage 28 In order to be discharged outside with dust. Therefore, the filter 2 is automatically cleaned. According to this embodiment, the air flow flows into the outer casing 21 through the air inflow 埠 21 a along the plane of rotation of the fan 22 . The blades 23 are formed such that they flow through the air into the raft 21 a. The side edges 23b of the vanes 23 on the upstream side of the air flow extend in the radial direction of the fan 22; this is formed by the air flow propulsion direction and the side edges 23b of the vanes 23. The angle of intersection is small. Therefore, it is possible to reduce a pressing force generated when dust collides with the side edges 23b of the blades 23, and thus the amount of dust adhering to the blades 23 is reduced. Further, due to the air flow and the centrifugal force, the dust collected by the side edges 23b of the blades 23 is directed toward the outer circumferential side of the blades 23, thereby further reducing the amount of dust adhering to the blades 23. may. Therefore, it is possible to easily reduce the amount of dust accumulated between the side edges of the vanes 23 and between the vanes 23 in the cleaning device 10. ❹ In addition, the fan 2 is formed to have a thirst flow fan. This makes it possible to easily flow the air flow in the outer casing 21 in the outer circumferential direction, and the air flows out of the crucible 21. Formed along the outer circumferential direction. Accordingly, it is possible to easily reduce the amount of accumulated dust. Here, the fan 2 is not limited to the _ thirsty fan; the same effect can be provided by a centrifugal fan such as a 45 ^ I; However, the use of a & vortex fan to form the fan 2 causes a reduction in the number of blades 23 due to its high static pressure. & This makes it possible to further reduce the amount of dust accumulated between the blades 23 as a possible J month t*. In addition, the vortex fan is used to increase the rotational speed compared to a multi-page fan ‘for the same amount of wind. 143780.doc -14- 201020483 Therefore, it is possible to increase the centrifugal force and thus the amount of dust adhering to the blades 23. Further, the fan 22 has the boss 22b surrounding the center of rotation of the fan 22 and adjacent to the air inflow port 21a, and the blades 23 are formed so as to be opposed to the outer edge of the air inflow 埠2la from the convex portion The circumference of the seat 22b extends outwardly; accordingly, the blades 23 are formed such that the side edges 23b of the blades 23 substantially parallel to the plane of rotation of the fan 22 are configured to flow through the Air flows into the upstream side of the air stream of 埠2丨&. Therefore, it is possible to easily make the angle of intersection formed by the air flow and the side edges (side edges 23b) of the blades 23 on the upstream side small. Here, the blades 23 are easy to extend at least to the air. It flows into the outer edge of 埠2ia. Further, the blades 23 on the side of the bottom plate 21b opposite to the side where the air flows into the 埠2 1 & side are interconnected via the annular ring 22c so as to be reinforced. The blades 23 may be reinforced on the side of the bottom plate 21b via the blades 23 interconnected by a support member such as a plate-shaped disk. However, the use of a plate-shaped support member causes the inside of the outer casing 21 to be separated into an air inflow side 2a side and a bottom plate 21b side. Accordingly, when the fan motor 24 having a large amount of movement in the axial direction of one of the motor shafts 24a is used, a static pressure is generated on the side of the air inflow port 21a and a static pressure is on the side of the bottom plate 21b. One difference between them causes the fan 22 to be pushed toward the air into the side of the crucible 21a. Therefore, the side edges 23b of the vanes 23 on the upstream side can be rubbed against the outer casing 21. Therefore, the blades 23 are interconnected on the side of the bottom plate 21b via the ring 22c, and it is possible to form a large opening area on one side with respect to the air inflow 丨2丨a. There is no opening portion of the gap enclosed between the blades. This makes it possible to prevent the blades 23 and the casing 2 from being displaced in a sliding manner. In addition, this allows dust accumulated between the blades 23 to easily fall through the opening portion, and thus avoids blocking the gaps between the blades 23 due to dust. The configuration of this embodiment is outlined as follows: (1) The air flow passing through the air inflow port 21a flows along the plane of rotation of the fan 22, and the inflow direction of the air flow and the rotation of the fan 22 The axes are substantially perpendicular to each other. (7) If the side edges 23b of the leaves on the upstream side are visible from the side, the axis of rotation of the fan 22 is substantially perpendicular to each other. (3) As seen from the side, the inflow direction of the air flow flowing through the air inflow 璋2ia is substantially parallel to the side edges of the vanes 23. (4) The vanes 23 are configured to be perpendicular to the plane of rotation of the fan: and the side edges on the upstream side are not inclined forward in the direction of rotation of the fan 22. Next, an air conditioner according to the second embodiment will be described. Fig. 8 is a side cross-sectional view schematically showing a fan unit 20 of a cleaning device of an air conditioner according to this embodiment. For convenience of explanation, the same components as those in the above-described first embodiment of the reference drawings! to 7 will be identified by the same reference symbols. The air conditioner of this embodiment is different from the air conditioner of the first embodiment in the shape of the blades U of the cleaning device 1 143780.doc -16 - 201020483. The other parts are the same as those in the first embodiment. The vanes 23 of the fan 22 are formed so as to extend outwardly from the circumferential surface of the boss 22b with respect to the outer edge of the air inflow weir 21a, and each vane is formed perpendicular to the fan 22 One of the curved surfaces is pressed against the surface 23c. The vanes 23 are liable to be formed up to the outer edge of the void 1a, and may be formed to have a flat surface. Further, the blades 23 are formed such that the side edges 23b of the blades 23 on the side of the air flowing into the weir 21a are disposed on the upstream side of the air flow flowing through the air inflow port 21a. And the side edges 23 are lowered from the inner circumferential side of the vanes 23 to the vanes 23 as the distance from the air inflow weir is observed in the axial direction of the fan External circumferential side. The side edges 23b of the vanes 23 on the upstream side are formed to rotate with the fan 22 with respect to the air flow flowing through the air inflow port 21a as indicated by the arrow line B3. One of the planes increases the distance in the radial direction of the fan 22 toward the circumferential side of the blades 23. Accordingly, the air flow flowing into the outer casing 21 is in contact with the vanes 23 at a further smaller angle of intersection than the first embodiment. Therefore, it is possible to further reduce the amount of dust accumulated on the blades 23. The side edges 23b of the vanes 23 may be formed to rise from the inner circumferential side of the vanes 23 to the distance as viewed in the axial direction as a distance from one of the air inflows 21a The outer circumferential side of the blade 23 is equal. Accordingly, the side edges 23b are formed to extend in the radial direction, and thus are formed by an angle formed by the flow of the air as compared to the first embodiment of the first and 143780.doc -17-201020483 In the case of g # & thus X is large and it is possible to reduce the amount of accumulated dust compared to the conventional technique. The configuration of this embodiment is outlined as follows: 2): the air flow moving through the air inflow enthalpy 21a is passed along the fan 22 § plane, and the flow direction of the air flow is opposite to the fan 22 The axes of rotation are substantially perpendicular to each other. (2) the side edges of the vanes 23 on the upstream side are said to be formed in a descending manner such that a portion of the side edges 2 on the outer circumferential side are observed in the axial direction as Keep away from this air flowing into the crucible 21a. W circulates the air stream flowing through the air into the crucible (1) along the side edges 2 3 b of the vanes 23. (4) providing the blade phantoms perpendicular to the plane of rotation, and the ends of the blades 23 on the upstream side and the direction of rotation of the fan 22 are not inclined forward. Next, an air conditioner according to a third embodiment will be described. Fig. 9 is a side cross-sectional view schematically showing one of the fan early elements 20 of one of the air conditioners cleaning device 10 according to this embodiment. For convenience of explanation, the same components as those in the above-described first embodiment with reference to Figs. 1 through 7 will be identified by the same reference symbols. The air conditioner of this embodiment differs from the air conditioner of the first embodiment in the shape of the fan 22 and the shape of the air flowing into the weir 21a in the cleaning device 10. The other parts are the same as those in the first embodiment. In the fan unit 20 of this embodiment, the casing 21 has a disk 21d' coaxial with the fan 22 to thereby form the air inflow port 21a. In addition to the 143780.doc -18-201020483, the fan 22 is formed with a centrifugal fan, wherein the bottom plate 22a is provided with the blades 23 perpendicular to the plane of rotation. The side edges 23a of the weir blades 23 on the inner circumferential side are disposed inwardly with respect to the air flow, and an inner edge of one of the inlets 21a is disposed such that the side edges 23 & The air stream of 21a is in contact. The side edges 23b of the vanes 23 facing the air inflow port 21a are formed so as to extend in a direction substantially parallel to the radius of the plane of rotation of the fan 22. Thus, the side edges 23b are formed so as to extend from the inner edge of the air inflow 埠2 1 a to the outer edge of the air inflow 埠 21 a. Accordingly, the side edges 23b of the vanes 23 are disposed on the upstream side of the air flow flowing through the air inflow weir 21a. According to this embodiment, as in the first embodiment, the air flow propelling direction intersects the side edges 23b of the vanes 23 on the upstream side at a small angle. Therefore, it is possible to easily reduce the amount of dust accumulated at the side edges 23b of the blade 23 on the upstream side and between the blades 23. Here, the side edges 23b of the vanes 23 may be formed in a descending manner as in one of the second embodiment i. The configuration of this embodiment is summarized as follows: (1) the air flow flowing through the air inflow port 21a flows along the plane of rotation of the fan 22, and the inflow direction of the air flow and the fan 22 The axes of rotation are substantially perpendicular to each other. (2) The side edges 23b of the vanes 23 on the upstream side and the axis of rotation of the fan 22 are substantially perpendicular to each other as seen from the side. (3) If visible from the side, the air flow flows through the air inflow 丄2丄a 143780.doc -19- 201020483 The side edge 23b is substantially in phase with the parallel direction of the blades 23. W provides the vanes & perpendicular to the plane of rotation of the fan 22 and the ends of the vanes 23 on the upstream side are not tilted forward in the direction of rotation of the fan. Next, an air conditioner according to the fourth embodiment will be described. 10 and 11 each schematically show a perspective view and a side view of the fan 22 in the air conditioner according to this embodiment. For convenience of explanation, the same components in the above-described first embodiment with reference to Figs. 1 through 7 will be identified by the same reference numerals. In Fig. 1G and Fig. u, only one blade 23 is shown for the purpose of the shape of the blades 23, and the other plurality of blades 23 are omitted from the drawings. The air conditioner of this embodiment is different from the air conditioner of the first embodiment in the shape of the blades U in the cleaning device 1''. The other parts are the same as those in the first embodiment. The vanes 23 of the fan 22 are formed to extend outwardly from the circumferential surface of the boss 22b and are formed in a curved surface that is inclined with respect to the plane of rotation of the fan 22. On the side of the air inflow port 21a of the outer casing 21, the blades 23 are inclined rearward in the direction of rotation r of the fan 22, on the side of the bottom plate 21b of the outer casing 21, the blades 23 are in the fan This rotation direction R is inclined forward. Correspondingly, as shown in Fig. u, an angle α formed by the inclination direction D of one end of the blade 23 on the side of the air inflow 淳 21 a and the rotation direction R of the blade 23 is obtained. An obtuse angle. With respect to the rotational direction R, the end of the blade 143780.doc • 20 - 201020483 23 on the side of the air flowing into the weir 21a is guided in a direction that allows the release of dust when striking the end. Therefore, the dust is no longer pressed against the side edge 23b. Therefore, according to this embodiment, it is possible to provide the same effect as the first embodiment, and the dust and the blades 23 are reduced due to the rotation of the fan 22. A pressing force generated when the side edges 23b collide with each other. The blade shapes of this embodiment are not limited to the shapes shown in Figs. 10 and U. For example, as shown in FIG. 12, the flat blades 23 can be tilted rearward in the direction of rotation R on the side of the air inflow 埠 21 a of the outer casing 21, and on the side of the bottom plate 2 1 b of the external yoke 21 The flat blades 23 are inclined forward in the rotation direction R. Further, as shown in Fig. 13, the vanes 23 may be formed to have portions that are only inclined to the vicinity of the side edges 23b. Further, as shown in Fig. 14, the side edges 23b may have a slope by a chamfered portion 23d formed on the pressing surface 23c on one side of the side edges 23b. The configuration of this embodiment is outlined as follows: (1) the flow of air flowing through the air inflow 埠 21 a flows along the plane of rotation of the fan 2 2 φ and the direction of flow of the air flow with the fan The axes of rotation of 22 are substantially perpendicular to each other. (2) The side edges 23b of the vanes 23 on the upstream side and the axis of rotation of the fan 22 are substantially perpendicular to each other. (3) If viewed from the side, the k-in direction through which the air stream flows into the weir 21a is substantially parallel to the side edges 2 3 b of the vanes 2 3 . (4) The ends of the vanes 23 on the upstream side are inclined rearward in the rotational direction. 143780.doc • 21 201020483 Although the first to fourth embodiments relate to the arrangement in which the dust is discharged to one position outside the room, it is not particularly limited thereto. For example, in the case where the indoor unit 1 is placed in one of the rooms without walls facing the outside, it is difficult to guide the exhaust passage 28 to the outside of the room β correspondingly, via the air The outflow 埠 21 c discharges the dust into a dust box disposed in the room. This makes it possible to regularly reduce the trouble of cleaning the filter 2. From the standpoint of satisfying the aesthetic appearance and the installation space, it is more desirable that the dust box is disposed in the indoor unit 1. Further, although the cleaning device 10 is intended to remove dust collected by the filter 2 and dust accumulated on the blades 23, it is not limited thereto. The cleaning device 10 cleans the outer panel, the heat exchanger 3, a blower fan that discharges the conditioned air, and an assembly such as a louver, constituting the air passage through which the conditioned air passes. a plurality of oils adhering to the dust adsorbing chamber in the filter 2 and the outer panel, dust adhering to the heat exchanger 3, the blower fan, the blinds, and the like are contained by condensation particularly during air cooling Many of the moisture. Each type of dust tends to adhere to the blades 23 of the fan 22 within the cleaning device 10. In any case, the use of the cleaning device of any of the above embodiments may reduce the amount of dust adhering to the blades 23. Further, the example of the fan 22 includes not only a centrifugal fan but also an axial fan or a pair of angle fans. In either case, as described above, the side edges of the vanes 2 3 on the upstream side (the air flow flowing through the air inflow weir 21a is in contact with the side edges) are formed so as to This radial direction extends, thereby making it possible to reduce the amount of accumulated dust. 143780.doc • 22- 201020483 As will be described below, irrespective of the flow of air through one of the air inflows 21a, it is possible to reduce the amount of accumulated dust depending on the arrangement of one of the blades 23. Fig. 15 is a sectional view showing one of the blades 23 arranged in the same manner as in the first to third embodiments. Figure 16 is a cross-sectional view of the blades 23 covering the same arrangement as in the fourth embodiment (Figure 12). Examples of such illustrations include not only the arrangement of the vanes 23 of the centrifugal fan but also the arrangement of the vanes 23 with an axial fan and a pair of angle fans. Further, Fig. 17 and Fig. 18 are each a cross-sectional view showing the arrangement of one of the blades 23 as a comparative example. In Fig. 15, a direction in which a resultant force F is obtained by combining an impact pressure received by the pressing surface 23c which is rotated by a centrifugal force imposed on the blades 23 by the blades (10), The pressing surface 23c is formed at an angle of 90 from one of the side edges 23e of the vanes 23 on the upstream side (corresponding to 23b in Figs. 7 to 9). . The angle θ formed by the direction r of the resultant force r direction and the side edge of the blade 23 on the upstream side (corresponding to 23b in Fig. 12) in Fig. i6 is an obtuse angle. Figure 17 covers the configuration of the 'Half blade 23' which is the same as the blade configuration of the conventional example shown in Fig. 19, wherein the side edge 23e of the blades 23 on the upstream side corresponds to 23a in Fig. 19. And the angle θ is an acute angle. Also in Fig. 18, the angle θ is an acute angle. As the comparative examples indicate 'when the angle e is an acute angle, the impact pressure received by the side edge 23e and the centrifugal force are a positive pressure (the force acting in the direction of pressing the dust against the side edge 23e) (4) Ground, dust 143780.doc • 23· 201020483 tends to accumulate on the side edge 23e. In contrast, by making the angle Θ equal to or greater than 90. (Figs. 15 and 16), the impact pressure and the centrifugal force received by the side edge 23e of the vanes 23 on the upstream side are zero or negative pressure (one of the dust is scraped from the side edges 23e) The force that works in the direction). Therefore, even if a pressing force is applied to the side edges 23e in accordance with the air flow speed, it is possible to reduce the amount of dust accumulated on the side edges 23e. When considering the air flow velocity, as long as the fan 22 is formed to have a centrifugal fan, it is advantageous that the air flow flows through the air at an angle as close as possible to a right angle with respect to the rotational axis of the fan 22. Flowed into 埠21a. In other words, it is preferable that the inflow direction form an angle as small as possible with respect to the plane of rotation of the blades 23. To this end, it is necessary to reduce the height of the air flow flowing through the conduit (side surface portion 25d) in the axial direction of the fan 22. Further, in the case where the fan 22 is formed to have one of a pair of angle fans or an axial fan, it is possible to eliminate such a limitation. Any of the embodiments described herein is applicable to an air conditioner equipped with a cleaning device of one of the filters of the cleaning-air conditioner.
