The blowing air from (2) is controlled so as to stop at a position where a predetermined vertical angle is set in advance. When a general stepping motor is used as the drive means (8), the reference position for the rotational movement of the first blade (9) and the second blade (14) is set, and the predetermined position is set from the reference position. A predetermined drive signal is issued from the control device to the stepping motor so that the rotation is stopped at.

FIG. 9 shows, for example, Japanese Patent Laid-Open No. 62-147256.
It is a perspective view which decomposes | disassembles and shows the wind direction change mechanism of the other conventional air conditioner shown by the publication. In the figure, (1
9) is a vertical airflow direction changing blade arranged at the air outlet (not shown) of the indoor unit, (20) is a shaft provided along the length of the vertical airflow direction changing blade (19), and (21) is a shaft (20) This is a first electric motor for rotating the up / down airflow direction changing vane (19) via.

(22) is a first left / right airflow direction changing blade which is composed of three blades connected to each other and is arranged on the right side of the air outlet,
3) is a second electric motor for rotating the first left / right airflow direction changing blade (22). (24) is a second left / right airflow direction changing vane, which is composed of three blades connected to each other and is arranged on the left side of the air outlet,
5) is a third electric motor for rotating the second left / right airflow direction changing vane (24).

In the conventional air conditioner configured as described above, as in the air conditioners shown in FIGS. 7 and 8, the vertical airflow direction changing blades (19) are driven by the first electric motor (21) to rotate. It is dynamically displaced to change the vertical wind direction at the outlet (2). As the type of the first electric motor (21), a stepping motor is generally used, but an induction motor may be used.

[0011]

In the conventional air conditioner as described above, in the case of FIGS. 7 and 8, the vertical airflow direction changing blades are connected to each other by the first blade (9) and the second blade (14). Ingredient

As a result, the stop positions of the first blade (9) and the second blade (14) when the air outlet (2) is closed differ from each other, resulting in incomplete closing and poor appearance. Further, when the first blade (9) and the second blade (14) are arranged at the reference position with respect to the air outlet (2), the convex piece (13) of the first blade (9) becomes the nozzle (3).
Engage with the protrusion (5). However, if there is an error in the position of the convex part (5), the nozzle (3) is a large synthetic resin molding member when correcting the position of the convex part (5), so it is very difficult to correct the molding die. Takes a lot of trouble.

Further, in the conventional air conditioner shown in FIG. 9, since a single up / down airflow direction changing vane (19) is provided at the air outlet, the longitudinal dimension of the up / down airflow direction changing vane (19) is reduced in manufacturing. ,
It is limited due to reasons such as ensuring rigidity. Therefore, there is a problem that the longitudinal dimension of the air outlet is limited and the degree of freedom in design is reduced.

The present invention has been made in order to solve the above problems, and has a structure in which the vertical airflow direction changing blade is constituted by two blades whose lengths are arranged in series at the air outlet of the indoor unit. It is an object of the present invention to obtain an air conditioner in which two blades easily and normally rotate.

[0044]

As described above, the present invention is arranged near the driving means of the air outlet and pivotally attached to the indoor unit via the axis line along the longitudinal direction and driven by the driving means to be rotationally displaced to move up and down the air outlet. A first blade that changes the wind direction and a rotation blocker that is provided near the anti-driving means of the air outlet in the same manner as the first blade and is connected to the facing end surface of the first blade through a connecting tool and is provided in the indoor unit. The second blade is disposed closer to the first blade than the first blade.

As a result, when the first blade and the second blade are closed, the first blade is further driven after the second blade hits the rotation blocker provided in the indoor unit and stops, and the connecting portion is connected. The play of motion due to a gap or the like is absorbed and hits the rotation blocker to stop. Therefore, when the first blade and the second blade both hit the rotation blocker and stop at the normal closed position to close the outlet, the stop positions of the first blade and the second blade differ, resulting in incomplete blockage. It has the effect of eliminating the problem of poor appearance.

Further, since the first blade and the second blade are provided at the air outlet, the longitudinal dimension of the vertical airflow direction changing vane is large in the case of the construction in which one vertical airflow direction changing vane is arranged, in terms of manufacturing, securing rigidity, etc. There is an effect of solving the problem that the longitudinal dimension of the air outlet is limited and the degree of freedom in design is reduced due to the restriction due to the above reasons.

A first blade and a second blade are provided which are connected to the output shaft of the driving means and are driven to be rotationally displaced to change the vertical air direction of the air outlet. As a result, the first blade and the second blade driven by the drive unit rotate in synchronization.

Therefore, when the first blade and the second blade stop at the normal closed position and the outlet is closed, the stop positions of the first blade and the second blade are different from each other, resulting in incomplete closing and a good appearance. It has the effect of eliminating the problem of deterioration. Moreover, since the first blade and the second blade are provided at the outlet,
In the case of a configuration in which one vertical airflow direction changing vane is arranged, the longitudinal size of the vertical airflow direction changing vane is restricted due to the convenience of manufacturing and ensuring rigidity, etc. This has the effect of solving the problem that the degree of freedom in design is reduced.

Further, as described above, the present invention provides a driving means provided in the indoor unit and arranged to face the air outlet, and is pivotally connected to the indoor unit via the longitudinal axis on one side of the air outlet. A first blade that is attached and is driven to rotate by the output of the driving means to change the vertical airflow direction of the air outlet; And a second blade connected to the first blade, and a fitting piece provided in the indoor unit corresponding to the connecting tool, and provided on any of the first blade, the second blade, and the connecting tool. A convex portion is provided to prevent rotation of the convex pieces facing each other at a predetermined position.

As a result, the rotation reference positions of the first blade and the second blade driven by the drive means are such that the convex piece provided on any one of the first blade, the second blade and the connector is the fitting piece. It is set by hitting the convex portion. Therefore, if a difference in the rotation reference position occurs due to an error in the nozzle of the outlet, the related member such as the first member, it is only necessary to rework the convex portion, which is a small component, and to form a large synthetic resin. There is no need to modify the mold of the nozzle, which is a member, and the position can be easily modified, and the manufacturing cost can be reduced.
