BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blowing device for a local air conditioner used in factories and the like.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for local air conditioners to improve the thermal workplace as a part of improving the working environment and securing human resources in factories. Among them, space-saving type and easy to install. The floor-standing ones grow significantly.

Conventionally, this type of local cooling machine generally has a structure as shown in FIG. The configuration will be described below with reference to FIGS. 4 and 5. As shown in the figure, the body 101 of the conventional local air conditioner has an indoor unit 1
02 and the indoor unit 102, an outdoor unit 103 is provided, and a base 104 is provided below the indoor unit 102 and the outdoor unit 103. Further, in the indoor unit 102, an indoor heat exchanger 105 and an indoor blower 106 are provided behind the indoor heat exchanger 105, and the indoor blower 106 is provided.
A blowout duct 107 is provided above. In addition, the outdoor unit section 103 includes the indoor unit section 102.
An outdoor heat exchanger 108 is provided on the opposite side, and an outdoor blower 109 is provided between the outdoor heat exchanger 108 and the indoor unit section 102. Further, the base portion 104 has a compressor (not shown) below the outdoor unit portion 103 and a drain tank 110 below the indoor unit portion 102. A blowing port 111 is attached to the tip of the blowing duct 107. The outlet 111 has a plurality of louvers 112 formed in a plate shape.
Was fitted and attached to the fixed plate 113 by the pin portion 114, and the fixed plate 113 was attached to the blowout port 111 by the screw 115.

In the above structure, when the blowing direction is wide type, all the louvers 112 are directed outward, and when the blowing direction is spot type, all the louvers 112 are directed inward. Become.

[0005]

In the structure of the blowing device of the conventional local air conditioner, it is necessary to adjust the direction of all the louvers 112 every time the blowing direction is changed to the wide type or the spot type. There was a problem that it was very time-consuming.

The present invention solves the above-mentioned problems and provides a blowing device for a local air conditioner in which the blowing direction can be easily switched between the wide type and the spot type simply by adjusting the positions of the two louvers. The purpose is to

[0007]

In order to achieve the above object, a blower device for a local air conditioner of the present invention has a blowout duct for blowing cold air connected to the local air conditioner and a blowout port connected to the blowout duct. And two curved louvers having an outwardly curved tubular portion on the windward side are symmetrically arranged and movably provided at the outlet.

[0008]

With the above construction, the present invention makes it possible to switch the blowing direction between the wide type and the spot type by simply changing the directions of the two louvers, and the switching work can be facilitated.

[0009]

EXAMPLES Examples of the present invention will be described below with reference to FIGS.
Will be described with reference to. As shown in the drawing, a blower outlet 2 that is hollow and substantially fan-shaped is provided at the end of a blowout duct 1 that blows out cool air connected to a local air conditioner (not shown), and is curved outward. A curved louver 3 having a tubular portion 3a on the windward side is provided rotatably symmetrically with respect to a fixed plate 5 by a support pin 4, and the fixed plate 5 is mounted in the blowout port 2 by a screw 6. There is.

In the above structure, when the blowing direction is wide type, the louver 3 is rotated with the support pin 4 as a fulcrum so that the leeward side of the two symmetrically provided louvers 3 faces outward. When the louver 3 is positioned as shown in FIG. 2, the cool air blown from the blowout duct 1 to the blowout port 2 is blown at the center of the blowout port 2 as shown by an arrow A, and the louver 3 has a cylindrical shape. The air flows along the curved louver 3 through the portion 3a, spreads outward as shown by an arrow A1, and is blown in a wide range.

When making the blowing direction the spot type, as shown in FIG. 3, the louver 3 is rotated around the support pin 4 so that the leeward side of the two symmetrically provided louvers 3 faces inward. When the louver 3 is positioned, the cool air sent from the air outlet duct 1 to the air outlet 2 is sent at the center of the air outlet 2 as shown by the arrow B, and passes through the tubular portion 3a of the louver 3. , Curved louver 3
And flows toward the central portion as shown by arrow B1.

[0012]

As is apparent from the above embodiments, according to the present invention, two curved louvers can freely change the direction in the blowout port provided in the blowout duct for blowing cold air connected to the local air conditioner. Since they are provided symmetrically, it is possible to provide a blowing device for a local air conditioner in which the blowing direction can be easily switched between the wide type and the spot type by changing the leeward direction of the two louvers.
