- the present inventors have found that the user feels comfortable when the temperature difference is set so as to be lowered by about 1 ° C. and the indoor upper space has a wind speed of about 0.5 m / s at which a feeling of moderate airflow is felt. .) For this reason, it is preferable to control the drive source 38 and the drive source 40 so that the upper blade 20 moves to the position shown in FIG. Thereby, as shown in FIG. 11 or FIG. 12, the air which blows off from the blower outlet 10 can be distributed in two directions, the direction along a ceiling surface, and the direction which goes to a user.
- the drive source 38 and the drive source 40 are controlled so that the upper blade 20 moves to the parallel position B ⁇ b> 1 and the angle of the vertical wind direction changing blade 12 is downward. It is preferable.
- the air (warm air) warmed inside the indoor unit during heating tends to float upward from the air outlet 10, but the upper blade 20 moves to the parallel position B ⁇ b> 1 and the angle of the up / down air direction changing blade 12.
- the air (warm air) which blows off from the blower outlet 10 can be supplied toward a floor surface, and the temperature of a user's step can be made high.
- the air blown out from the blower outlet 10 can be distributed in two directions, a direction along the ceiling surface and a direction toward the user's feet, and efficiently warms the room. Energy-saving heating can be realized.
- the movement of the upper blade 20 to the serial position B2 is not limited to cooling, and may be performed during heating.
- the movement of the upper blade 20 to the parallel position B1 is not limited to heating, but may be performed during cooling. That is, when the distance from the blower outlet 10 to the target point for supplying air is long, the upper blade 20 is moved to the series position B2, and when the distance from the blower outlet 10 to the target point for supplying air is short, the upper blade 20 May be moved to the parallel position B1.
- the temperature difference between the indoor upper space and the lower space that the user feels comfortable varies.
- FIG. As shown in FIGS. 3, 5, and 7, by adjusting the distance between the lower blade 18 and the upper blade 20, the air blown out from the air outlet 10 in two directions (for example, the upper space and the lower space). It is possible to adjust the air volume of the air to be distributed. Thereby, the temperature difference between the upper space and the lower space can be controlled to a desired value.
- the length of the vertical wind direction changing blade 12 is maximized. Can be made apparently longer with a smaller number of parts (two). Moreover, since the upper blade
- the present invention is not limited to the above-described embodiment, and can be implemented in various other modes.
- the rotation shaft 22 of the lower blade 18 is fixed at a fixed position
- the rotation shaft 24 of the upper blade 20 is configured to be movable.
- the present invention is not limited to this.
- the upper blade 20 and the lower blade 18 are kept at a predetermined distance, and the link blades 36a and 36b are fixed without pivoting while the upper blade 20 and the lower blade 18 are kept in a relative position. You may make it rotate centering on the moving shaft 22.
- the rotation shaft 24 of the upper blade 20 may be fixed at a fixed position, and the rotation shaft 22 of the lower blade 18 may be configured to be movable. That is, it is only necessary that one of the lower blade 18 and the upper blade 20 is fixed at a fixed position and the other of the lower blade 18 and the upper blade 20 is movable.
- the lower blade 18 and the upper blade 20 are connected by the pair of link arms 36a and 36b so as to maintain a substantially parallel state, but the present invention is not limited to this.
- the lower blade 18 and the upper blade 20 may be connected by a member such as a jack.
- the upper blade 20 moves in front of the lower blade 18 and is connected in series with each other.
- the present invention is not limited to this.
- the upper blade 20 may move behind the lower blade 18 and be connected in series with each other.
- the air conditioner according to the present invention can be used in ordinary households because the length of the up-and-down wind direction changing blade can be apparently increased with a smaller number of parts to obtain a higher air rectification effect. It is useful as various air conditioners including air conditioners.
