Description

  The present invention relates to an air conditioner.

  In conventional air conditioners, by optimizing the shape and arrangement of the left and right blades that change the wind direction at the outlet of an indoor unit in the left-right direction, the wind speed at the outlet is increased and the reachability of the outlet is improved. There is a technique for improving the comfort of a living space (see, for example, Patent Document 1).

  FIG. 9 is a partial vertical sectional view of an indoor unit of a conventional air conditioner, and FIG. 10 is a plan sectional view of the outlet. In FIG. 9, the indoor unit is located around the front cover 101, the air inlet 102 provided in the front cover 101, the heat exchanger 103, the blower fan 104, and the blower fan 104, and forms a blower path 107. The rear guider 105, the stabilizer 106 that is close to the blower fan 104 and forms the blower passage 107 with the rear guider 105, the wind blowout port 108 at the tip of the blower passage 107, and the wind direction at the blowout port 108 in the vertical direction (vertical direction) The upper and lower blades 109 that rotate up and down about the axis to change the direction of the air) and the left and right are composed of a plurality of right and left rotating about the axis to change the wind direction at the outlet 108 in the horizontal direction (left and right direction). And a blade 110.

  In FIG. 10, reference numeral 108a denotes a central portion of the outlet 108, 108b denotes both end portions of the outlet 108, 110a denotes left and right blades positioned at the outlet central portion 108a, and 110b denotes left and right blades positioned at the outlet end portions 108b. The left and right blades 110 (both the left and right blades 110a at the center of the air outlet and the left and right blades 110b at both ends of the air outlet) are arranged in parallel to the longitudinal direction of the air outlet 108, and the surfaces of the blades are straight and vertical. The left and right blades 110a at the center of the outlet are oriented in such a direction that the air is discharged straight to the front. On the other hand, the left and right blades 110b at both ends of the outlet rotate to shield both ends 108b of the outlet.

  The air flow will be described with reference to FIG. The room air is sucked from the suction port 102 provided in the front cover 101, passes through the heat exchanger 103, and is sucked into the blower fan 104. The air sucked into the blower fan 104 passes through the blower passage 107 and is discharged from the outlet 108.

  As shown in FIG. 10, when the left and right blades 110b positioned at both end portions 108b of the air outlet 108 are rotated, the both end portions 108b of the air outlet are flatly shielded, and an air passage to the air outlet central portion 108a is formed. Will do. The wind is difficult to blow out from both ends (shielded portions) 108b of the outlet, and converges on the central portion 108a of the outlet. Then, the wind is blown out from the central portion 108a of the air outlet through the space between the left and right blades 110a in the central portion of the air outlet where the air outlet is not shielded and the air blowing resistance is low.

  Here, if the left and right blades 110b at both ends of the air outlet are arranged so that part of the blades overlap when rotating, the wind is more difficult to blow out from the air outlet both ends (shielded portion) 108b. The convergence rate to the central portion 108a of the outlet is increased. And the speed of the wind which blows off from the blower outlet 108a of a center part increases.

Thus, if the same air volume is maintained, the wind speed increases as the cross-sectional area of the outlet 108 decreases.

Conventionally, the flow of air is intensively formed toward the living space by rotating the left and right blades 110 to shield a part of the outlet 108 in this manner.
JP-A-10-253143

  However, as described above, it has a wind direction device that simply rotates the left and right blades 110b at both ends of the air outlet to shield the both end portions 108b of the air outlet, thereby forming an air flow to the air outlet central portion 108a. In an indoor unit of an air conditioner, the air flow was originally poor at the both end portions 108b of the air outlet compared with the central portion 108a, and air tended to accumulate.

  Therefore, when the left and right blades 110b positioned at the outlet end portions 108b rotate and shield the outlet end portions 108b, the air flow at the outlet end portions 108b becomes worse and the air is in that position. Since it accumulates, a large load is also applied to the side of the blower fan 104 that sends the wind, and abnormal noise due to the flapping characteristic of the blower fan 104 is likely to occur.

  Further, since the left and right blades 110 are arranged in parallel to the opening surface of the outlet 108 and the surface of the blade is not inclined, when the left and right blades 110b located at both ends 108b of the outlet rotate, The both end portions 108b of the mouth are shielded flatly. For this reason, a collision flow occurs in the central portion 108a of the outlet where the flow is concentrated, or both ends (shielding portion) 108b of the outlet and the central portion of the outlet (outlet portion). An entrainment flow occurs at the boundary of 108a, and the wind speed decreases. Therefore, the effect of converging the air volume and intensively reaching a part where people are present or a part of the floor surface cannot be exhibited sufficiently.

  In addition, in the method of simply rotating the left and right blades 110 to shield the outlet 108, the shape of the left and right blades 110, the shape of the connecting portion for interlocking the plurality of left and right blades 110, and the connecting method are not modified. When the blade 110 is rotated and shielded, a gap is formed between the left and right blades, that is, a gap is formed in the portion to be shielded, the outlet 108 cannot be completely shielded, and the leakage flow occurs. As a result, it was difficult to sufficiently converge the air volume.

  The present invention solves the above-described conventional problems, and smoothes the air flow by the left and right blades, blows the air flow left and right, or increases the speed of the air flow to concentrate the person's part or floor. An object of the present invention is to provide an indoor unit of an air conditioner that reaches a part of the surface to improve the comfort of the living space.
