TECHNICAL FIELD The present invention relates to a wind direction changing device mainly used for an outdoor unit of an air conditioner.

2. Description of the Related Art In recent years, due to overcrowding of buildings, there has been a demand for space saving of outdoor units of air conditioners, noise reduction, and prevention of harmful effects of animals and plants. To meet this demand, Japanese Utility Model Publication No. 58-48992 discloses. The number of cases in which a wind direction changing device is installed at the outlet of an outdoor unit is increasing.

The conventional wind direction changing device for an outdoor unit described above will be described below with reference to the drawings. FIG. 11 is a perspective view showing a state in which a conventional wind direction changing device is attached to an outdoor unit so as to change the wind direction to the upper side, and FIG. 12 is a vertical sectional view showing the same state as in FIG. Reference numeral 1 is an outer box of the outdoor unit, which has a hole for arranging a blower in a part thereof and has a structure for covering the blower, the heat exchanger, and the like. 2 is a heat exchanger. A blower 3 generates an air flow in the direction of the arrow. A motor 4 is connected to the blower 3 and provides rotation. Reference numeral 5 is a protective net and is arranged for the safety of the blower 3. Reference numeral 6 denotes a main body of the wind direction changing device, and a horizontal frame 7, 7'and a vertical frame 8, 8'constitute a frame body. Reference numeral 9 denotes a plurality of wind direction changing plates, which are arranged in the frame body at appropriate angles. The body of the wind direction changing device is attached to the outer case 1 with the attaching screw 10. FIG. 13 shows the wind direction changing device body 6
Fig. 14 is a cross-sectional view of the outdoor unit when the blowout is changed to the left.
The figure is a cross-sectional view of the outdoor unit when the airflow direction changing device body 6 is changed to the right. The operation of the wind direction changing device configured as described above will be described below.

First, the air sucked from the heat exchanger 2 by the rotation of the blower 3 is blown toward the wind direction changing device 6 side through the protective net 5, and the wind direction is changed by the wind direction changing plate 9. The wind direction changing device 6 is rotated by 90 ° to change the wind direction to the right, the left, and the upward.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, since the conventional wind direction changing device for an outdoor unit described above can only change the wind direction in four directions of up, down, left, and right, the wind blown from the outdoor unit may be different depending on the installation location of the outdoor unit. There are drawbacks in that the air blown from the outdoor unit is impaired by hitting an obstacle, the heat exchange amount in the heat exchanger of the outdoor unit is reduced, and the noise is increased.
