Description of the invention (2) That is, 'Because most of the above-mentioned curved leaves are made at substantially the same distance from each other, due to the shape of the surface, the airflow at the right angle of the centrifugal fan to the longitudinal direction of the air outlet is slightly different from the rear side. The curved leaves are peeled off. On the one hand, if the angle of incidence of the airfoil that blows out the blades in the direction of a slightly right angle plane in the rotation direction of the centrifugal fan is gathered, the airflow will be effectively rectified, and if they are adjacent to each other due to the peeling The curved rectifying effect of the curved blades on the front side of the curved leaf fan in the direction of rotation, and to bend the blade interval so that the best effect of rectifying on the side will be sacrificed and therefore the air flow cannot be effectively rectified. [Disclosure of the Invention] An object of the present invention is to provide an air conditioner capable of reducing noise. In order to achieve the above object, the centrifugal fan of the present invention is provided in the casing with respect to an air conditioner that sucks air toward a shaft. The longitudinal direction of the air outlet is arranged above the air outlet, and the sheets are formed in the same shape. Moreover, if the front side of the curved turning direction of each curved purple sheet is blown out in the direction of the phase plane, the sheet will be damaged. Increasing the angle of incidence of the airfoil results in the shape of the curved surface of the crossbow blade. The rear side is longer than the longitudinal direction of the air outlet, that is, the airflow is more curved than the front side. The problem. Moreover, the interval between the blades is such that the rectification can obtain the best effect in the above-mentioned centrifugation. After sacrifice, the rectification effect of the curved blades on the front front side of the rotation direction of the centrifugal fans adjacent to each other can be effectively rectified and blown out.

Explanation of the invention (3) It can be bent towards a slightly vertical direction, and it can be increased toward the front side. If it depends on the air, it can be out of phase. In the present invention with a large curvature, for the longitudinal centrifugal sheet of the centrifugal sheet of 40 degrees and the centrifugal direction of the majority of the openings, the majority of the curved side of the centrifugal fan in the direction of rotation of the centrifugal fan that leads to the direction of rotation of the centrifugal fan are borrowed. The centrifugal fan blows from the front side of the air fan, and the tangent of the outer periphery blows out at an angle in the turning direction. And the airflow is rectified along the airfoil surface of the crossbow blades installed on the casing. At this time, the angle of the airflow opposite to the rear side of the turning direction of the fan is about to increase. The angle of the airflow relative to the longitudinal direction of the air outlet will be increased. It's going to get smaller. Therefore, the bending of the curved blades is increased from the rear side toward the front side of the centrifugal fan in the direction of rotation, so that the incident surface of the airflow of all the curved blades can be reduced, so that the airflow from the crossbow blades can be prevented from peeling off. The air outlet blows out the air rectified by the flat blade and the majority of the curved blades in a desired direction (for example, blows out along a plane at a right angle to the longitudinal direction of the air outlet). Therefore, the blown air from the above-mentioned centrifugal fan can be effectively flowed, and the voice can be reduced. In addition, according to the indoor unit of the air conditioner according to an embodiment, a region in which the plurality of curved blades are divided into a plurality of regions, and the bending sizes of the curved blades are made different for each of the plurality of divided regions. According to the above embodiment, since the bending sizes of the curved blades in the respective divided areas are the same, the bending length of all the curved blades is designed to be the same as the angle of the airflow in the direction relative to the air outlet. Compared with the best conditions, the design can be simplified, and the time can be simplified.

Description of the invention (4) The single structure is effective. In addition, several curved blades are reduced toward the front. If the above-mentioned majority of the curved sides are narrowed, the centrifugal fan rectifying effect of the curved leaves on the airflow side is rectified effectively. In addition, there are many of the above-mentioned pre-segmentation of the majority of the warp warps, and the interval between the pre-segmentation of the majority of the majority is the same, so the angle of the curved blades can be counted while the cost can be reduced. In addition, other implementations of ground rectification and reduction are based on the change of the blades from the adjacent blades of the above-mentioned embodiment from the angle of the centrifugal abutment interval, so that the direction of rotation can be suppressed without increasing the centrifugal fan. Each region of the number of regions of the blade makes each region of the embodiment described above an empty centrifugal space that is designed to have an optimal simple structure with a minimum of noise compared to all curved purples. Air-conditioned fans > Therefore, it is necessary to divide the cross-border leaves adjacent to each other in the area of the air that is not necessary to be blown away from the front of the rectifier. The indoor unit of the air conditioner, the rotation of the rear side throttle unit of the multi-fan rotation direction can see the concentric wind effect, the side of the main air is required, and the regulator is a piece of curved joint of the majority The way of the large air outlet curved surface is the ratio of the indoor unit, the direction of the fan relative to the rotation of the fan, the curved blade, the area of the indoor unit that reduces the noise under the flow effect, the size of the curved indoor space between the indoor unit, and The shape and comparison of each other's longitudinal squares can flow and decrease.

Description of the invention (10) ------ Air outlet 2 22) Blow out obliquely in front. At this time, as shown at 151, the air direction of the air blown out from the lower air outlet 24 is on the rear side of the rotation direction of the centrifugal fan 2, and the angle with respect to the longitudinal direction of the air outlet 24 is that of the centrifugal fan 2. The angle of the front side of the turning direction with respect to the air outlet in the longitudinal direction is 02 (< Sichuan, and the crossbow blades 13 with a wide interval and small bends with a large interval and narrow bends with a large interval and narrow bend) And the curved blades 14 and the flat blades 12 of the curved blades 13 and 15 are rectified and blown out along a plane that is slightly perpendicular to the longitudinal direction of the air outlet 24. Similarly, from The air from the other air outlets 21, 22, and 23 is also blown out along a plane that is slightly perpendicular to the longitudinal direction of each air outlet. Therefore, the air from the rear side of the centrifugal fan 2 in the direction of rotation increases toward the front side. The curvature of most of the curved blades 13, 14, and 15 reduces the incident angle of the airflow of all the curved blades 13, 14, and 15, and the air can be discharged from the wind along the longitudinal direction or right-angled plane relative to the air outlets 21 to 24. Mouth and "blow-out." Therefore, the blow-out air from the centrifugal fan can be effectively rectified, and noise can be reduced at the same time. Furthermore, the area where most of the above-mentioned crossbow blades 13, 14, and 15 are arranged is divided into areas A, B, and C. The bending size of the curved blades is different for each of the pre-divided areas A, B, and c. Therefore, the angle of the airflow in the longitudinal direction of the air outlet from 2 to 24 changes, and the curved surface shape of all curved blades is changed. Compared with the most appropriate design, the design can be simplified and the simple structure can achieve effective rectification, reduce noise, and reduce costs. Mm Page 13 V. Description of the invention (11) And 'By making the above-mentioned curved blade 13, 14, 15 The distance between the adjacent sides is reduced from the rear side to the front side of the centrifugal turning direction, so that the rectification of the rear side of the centrifugal fan 2 in the turning direction does not increase unnecessary air outlets 21 to 24. As a result, the rectifying effect on the front side of the centrifugal fan 2 in the turning direction of the air outlets 21 to 24 can be increased, so that the blown air from the centrifugal fan 2 can be more effectively rectified. At the same time, the noise can be reduced. Also, 'Because the flat blade 12 and the curved blades 13, 14, and 15 are formed by a skeleton, and the planar blade 12 also serves as a supporting member that supports the curved blades 13, 14, and 15,' the number of parts can be reduced, Simplify the structure of the air outlet and reduce the cost. Also, as shown in the fourth circle, when the plane blade 12 of the above-mentioned airflow control member 丨 is fully opened, the curved blades 13, 14, and 15 (only one _ curved blade is indicated in the fourth circle). 15) The leading edge 15a of the wind head side makes the incident angle of the airflow (03 shown in the fourth circle) almost the same for the wind direction of the blown air from the centrifugal fan 2. 'Therefore, there is less chaos in the airflow. In the above embodiment, the bending of the curved blades 13, 14, and 15 is increased from the rear side toward the front side of the rotation direction of the centrifugal fan 2. At the same time, the interval between adjacent curved blades is reduced, but From the rear side of the centrifugal fan 2 in the turning direction to the front side, it is possible to increase the warpage of the crossbow blades 13, 14, and 15 so that the intervals between the adjacent curved blades are slightly the same. The rear side toward the front side of the rotation direction of the blade so that the same crossbow curved shape of the curved surfaces 13, 14 of the narrow curved vanes adjacent to each other can also be spaced.

Description of the Invention (12) In the above embodiment, as shown in the third circle, three areas including the region A of the crossbow purple sheet 13 and the area b of the curved blade 14 and the area C of the curved blade 15 are divided. Area, and the bending size of the ridge curved blades 13, 14, and 15 and the interval between adjacent curved blades are set for each area A, B, and C. However, it is also possible to continuously change the curved size of the curved blade, or continuously change the curved blade The interval is OK. Furthermore, in the above-mentioned embodiment, although the flat blades and the curved blades are formed on one ship, it is also possible to combine the flat blades and the curved blades separately. Furthermore, in the above-mentioned embodiment, when the above-mentioned airflow control member n is fully opened, regardless of any area on the leading edge of the vane side of the test curved blades 13, 14, and 15, although the incident angle of the airflow is formed to be slightly the same, it is considered that it comes from a centrifugal fan The wind direction of the blown air may be appropriately set. [Industrial Applicability] As described above, the indoor unit of the air conditioner according to the present invention can be used for an air conditioner that blows out conditioned air in the up-down direction and the left-right direction.
