Conventional Technology Generally, a deflection device consisting of left and right deflection plates and upper and lower deflection plates is used as a means for deflecting the direction of the air blowing from an air conditioner from the direction of normal use. , the wind direction can be controlled in any vertical direction using the vertical deflection plate. Moreover, each has a structure that rotates around a fulcrum axis. (For example, Japanese Unexamined Patent Publication No. 59-161636) Problems to be Solved by the Invention Here, we will particularly focus on the upper and lower deflection plates. The upper and lower deflection plates, together with the left and right deflection plates, act as important resistance on the blowing side of the blower, causing deterioration in blower performance such as a decrease in air volume and an increase in noise. The rate of decline in blower performance differs significantly depending on where in the air passage the upper and lower deflection plates are placed.

Therefore, after optimizing the shape of the upper and lower deflection plates,
If the optimum position is selected, the performance of the blower will hardly deteriorate. However, even if the upper and lower deflection plates are rotated from the normal position around the fulcrum in this position to deflect the wind direction from the direction of normal use, it is generally not possible to select sufficient deflection performance.

Therefore, the conventional vertical deflection plates set their positions by prioritizing the vertical deflection performance, which is the original function, and this has been a factor in deteriorating the performance of the blower.

The present invention does not reduce blower performance in the normal position,
Moreover, it is an object of the present invention to provide a vertical deflection plate that has sufficient vertical deflection performance.

Note that good vertical deflection performance here means that the wind direction can be deflected at a large angle without significantly reducing the performance of the blower in the normal position. Further, the normal position is a deflection plate position where the air direction is set to the blowing direction that is assumed to be most commonly used, and the best blower performance is generally obtained at this position.

Means for Solving the Problems In order to solve the above problems, the present invention provides an air conditioner that includes an indoor air inlet, a heat exchanger, a blower, and an air outlet that blows out air after heat exchange. At the air outlet, a blowout angle a at which the blowout air volume is maximum and a maximum deflection angle b at which the blowout angle is maximum are set, and at angle a, the blowout direction deflection plate is set.
When the deflection plate position with the lowest air volume reduction rate at the same noise level is A, and the position where sufficient wind deflection is possible at angle b is B, then rotation such that both positions A and B are included in its rotation locus. The wind deflection plate is rotated around the axis.

Here, if the vertical deflection plate 1 is configured to simply rotate around the axis as shown in Fig. 3, when the vertical deflection plate 1 is tilted downward at 70 degrees at position A, the blowing air flow will change as shown by the arrow in Fig. 3. It flows like this and cannot change the direction of the blowing air. Conversely, if you turn the upper and lower deflection plates downward to 10 degrees at position B, the downward deflection angle of 10 degrees will be 10 degrees.
