Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a wind direction changing device installed in an air conditioner.

(b) Prior Art Conventionally, as a structural example of a wind direction changing device provided in an air conditioner, one disclosed in Japanese Utility Model Publication No. 59-22430 has been disclosed.

This content is such that the inside of this air duct is divided into an upper passage and a lower passage by a second wind direction plate extending in the horizontal direction within the air duct, and a first air direction plate extending in the vertical direction is provided at the bottom of this second air direction plate. A wind direction plate was integrally combined with this second wind direction plate.

By moving this first wind direction plate, only the airflow discharged from the lower passage is changed to the left or right.

(c) Problems that the invention aims to solve When the second wind direction plate is rotated until it becomes approximately horizontal, there is a gap between the lower end of the first wind direction plate and the lower wall surface of the discharge port (lower passage). It was not possible to change the flow direction of the wind along the lower wall surface.

The object of the present invention is to provide a wind direction changing device that can constantly change the direction of the airflow blown out along the lower wall surface of the lower passage.

(d) Means for solving the problem The wind direction changing device of the present invention has a horizontal blade installed approximately in the center of the air outlet of the housing, a vertical blade below the blade, and the upper end of the blade in a horizontal state. It is arranged below the blade and behind the spindle of the blade.

(E) Effect According to the device of the present invention, the airflow discharged along the lower outlet of the outlet is always guided in the left and right direction by the operation of the vertical blades, and is also discharged from the upper outlet of the outlet. The airflow is blown out in front of the air outlet.

(F) Example In Figs. 1 and 2, 1 is an indoor heat exchange unit of a separate air conditioner, and this unit has an indoor heat exchanger 2, a drain pan 3, and an indoor fan 4 built-in. . 5 is an indoor air inlet, 6 is a filter, and 7 is a horizontally elongated outlet.

Reference numeral 8 denotes a blade disposed at the blower outlet 7, which divides the inside of the blower outlet 7 into an upper blower outlet 10 and a lower blower outlet 11. This plate is located at the part of the outlet 7 where the wind speed is fastest. Both ends 1 of this blade 8
A support shaft 13 is protruded from 2. This support shaft 13
is supported by the side wall of the air outlet 7, and the blade 8 is configured to rotate in the direction of the solid line arrow in FIG. 1 with the support shaft 13 as a fulcrum.

14 is a control device that changes the airflow blown out from the lower outlet 11 in the left-right direction, and has a plurality of vertical blades 16 vertically installed on the lower wall surface 15 in the left-right direction, and these vertical blades 16 are connected to each other. It is comprised of a connecting rod 17 that always directs these blades in the same direction. Further, the size of the vertical blade 16 is determined so that the upper end of the blade is located below the horizontal blade 8. Furthermore, this vertical blade 16 is located further back than the blade 8.

In such a unit 1, when indoor air cooled by the indoor heat exchanger 2 is discharged from the outlet 7, the blade 8 is held in a horizontal position as shown in FIG. Further, the vertical blades 16 are set in any direction left or right.

In this way, as shown in FIGS. 1 and 2, the lower wall surface 15 of the lower outlet 11 of the outlet 7
The air flowing along is discharged downward from the air outlet 7 by the vertical blades 16. Moreover, the air guided to the upper part of the vertical blade 16 is discharged below the air outlet 7 without being influenced by the blade 8. In this way, the wind guided by the vertical blades 16 is reliably guided from the lower air outlet 11 to the customer's living space (lower part of the room). On the other hand, the air flowing through the upper air outlet 10 of the air outlet 7 is discharged forward of the air outlet 7 as it is. A part of the cold air is then guided to the upper part of the room 17. In this way, the air guided to the top of the room descends, cooling the entire room evenly.

Also, since the vertical blade 16 is positioned behind the spindle 13 of the blade 15, that is, the spindle 13 of the blade 8 is positioned in front of the vertical blade 16, the blade 8 is directed downward as shown by the solid line arrow in Figure 1. Even if the blade 8 is rotated, there is almost no possibility that the blade 8 will hit the vertical blade 16. Therefore, if the blade 8 is directed downward, the lower wall surface 1 of the lower outlet 11 of the outlet 7
5 and the flow of wind changed to the left or right by operating the vertical blades 16 can be reliably guided below the unit 1.

(G) Effect of the invention The device of the invention has a blade at the air outlet so that the air passing through the upper air outlet is discharged toward the front of the aircraft without being affected by the direction of the vertical blades at the lower air outlet. Therefore, especially during cooling operation, the cold air is discharged to the front of the unit and descends from the upper part of the room, so that the room can be evenly cooled.

In addition, since the vertical blades are installed behind the spindle of the blade and along the lower wall surface, there is no risk that the blades will hit the vertical blades even when the blades are rotated downward, and the discharge is discharged from the lower outlet. air can be reliably guided downward.

Further, since the upper ends of the vertical blades are located below the horizontal blades, the direction of the wind blown out from the lower air outlet can be constantly changed without being affected by the movement of the blades.
