Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a wind direction adjusting device for an air conditioner.

[0002]

2. Description of the Related Art An air conditioner for air conditioning (air conditioner) is provided with an air flow direction adjusting device such as a louver at its air blowing portion so that the air blowing direction can be variously changed. However, in the conventional air flow direction adjusting device provided in an air conditioner attached to a high place such as a wall in a room, the air blowing direction is limited to the range from the downward direction to the substantially horizontal direction. Therefore, cold air blows directly on the body during cooling, and many people complain of discomfort. In addition, some people dislike being hit by the hot air when heating. In particular, it is unfavorable for health while sleeping.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a mild and comfortable cooling system in which cold air or warm air does not directly contact the body. Alternatively, it is to provide an air-conditioning device for an air conditioner that can obtain a heating effect.

[0004]

An object of the present invention is to provide a wind direction adjusting device provided in an air blowing portion of an air conditioner mounted at a high place in a room; the air blowing direction is diagonally upward from the horizontal direction. This can be achieved by an air-direction adjusting device for an air conditioner, which is provided with a rotatable air-direction adjusting blade that can be changed within a range of at least 10 ° and at least 20 ° obliquely downward. Here, the "high place" in the room is
170c above the height of a normal person, that is, from the floor
It indicates a position higher than m.

With the above-described structure, it is possible to set the air blowing direction to an angle of 10 ° or more from the horizontal direction to the diagonally upward direction, so that cold air or warm air can be directly blown onto the body. The air blown out without hitting the ceiling once reaches the vicinity of the ceiling, and then slowly descends and spreads throughout the room, so that a calm and comfortable cooling and heating effect can be obtained.

In the present invention, the blowing direction of air is
The range is at least 10 ° diagonally upward from the horizontal direction and at least 20 ° diagonally downward. The reason is that if the angle is less than 10 ° diagonally upward from the horizontal direction, the effect of blowing cold air or warm air is increased. Is insufficient, and if it is less than 20 ° from the horizontal direction to the diagonally downward direction, it is inconvenient when it is desired to rapidly cool or warm the lower half region of the indoor space. The upper limit of the above angle is 90 ° both upward and downward, and in that case, the blown air will flow directly up or down along the front surface of the air conditioner. In the case of the embodiment shown in FIG. 1 which will be described later, when the upper blade and the lower blade are rotated by 90 ° in opposite directions, the air outlet is closed or is completely opened like a double door. It will be in a state of being. In the preferred embodiment, the rotatable range of the wind direction adjusting blade is such that the air blowing direction is a maximum of 30 ° obliquely upward from the horizontal direction,
It is configured so as to be obliquely downward and within a range of maximum 90 °.

The wind direction adjusting blade may be manually rotatable or may be rotatable by a motor. In some cases, the wind direction adjusting blade may be rotatable by a motor.
Both may be made selectable as appropriate.

The wind direction adjusting blade is, in a preferred embodiment thereof, pivoted at the upper edge of the air blowing portion within a range of at least 10 ° obliquely upward from the horizontal direction and at least 20 ° obliquely downward. An upper blade, which is attached as much as possible, and a lower edge portion of the air blowing portion, which is attached so as to be rotatable within a range of at least 10 ° obliquely upward from a horizontal direction and at least 20 ° obliquely downward. And a lower blade.

Alternatively, the wind direction adjusting blades are respectively provided outside the upper edge and the lower edge of the ventilation opening formed along the generatrix of the substantially semi-cylindrical hood rotatably attached to the air blowing portion. The upper blade piece and the lower blade piece projecting toward one side, wherein the upper blade piece and the lower blade piece are at least 10 ° diagonally upward from the horizontal direction and at least 20 ° diagonally downward. The semi-cylindrical hood may be configured to be rotatable within the range so that the direction can be changed.

Alternatively, the wind direction adjusting blade has an opening / closing operation centered on an upper rotation shaft provided at both ends of the upper side and an opening / closing operation centered on a lower rotation shaft provided at both ends of the lower side. It may be configured by one selectable bidirectional opening / closing blade.
