[Problems to be solved by the invention]

 However, in the conventional air conditioners shown in FIGS. 11 and 12, a flap c is provided at an air outlet b of the air conditioner body a itself, and the blowing direction of the conditioned air k such as the cold air k1 or the warm air k2 is simply moved up and down. The direction z is changed to select the reach l of the conditioned air k. Therefore, the cold air k1, whose specific gravity is heavier than ordinary room air, sinks on the floor of the room, and the cool air k1 passes through the upper part of the room, and it takes many hours for the room to be completely cooled to the set temperature. It takes. In addition, the warm air k2, which has a specific gravity lighter than ordinary room air, tends to accumulate near the ceiling surface, and it takes a lot of time to pass to the lower part of the room and heat the room to a desired set temperature. . As described above, conventionally, no measures relating to airflow control due to the specific gravity of the conditioned air k such as the cold air k1 or the warm air k2 have been taken, so that the convection of the cold air k1 or the warm air k2 smoothly occurs indoors. It was not performed, and the cooling or heating was insufficient to perform efficiently. Therefore, it is necessary to control the airflow in consideration of the convection-inhibitory factors caused by the specific gravity of the conditioned air k such as the cold air k1 or the warm air k2. As a result of long-term research, the present inventor devised the present invention. It has arrived.

According to the present invention, efficient and efficient cooling or heating can be performed by performing quick and reliable airflow control by a simple handling operation in accordance with the specific gravity of the conditioned air k such as cold air or warm air. The aim is to provide an auxiliary flap for an air conditioner that is easy to manufacture and assemble, and whose manufacturing cost is low.

The link 5 and the wind direction plate 7 are attached to the outside of the air conditioner body 1. In FIGS. 1 and 2, one wind direction plate 7 having a length L <b> 1 of substantially half or less of the length of the front opening of the outlet 2 is rotatably linked via a fixed portion 6 to one link. 5 is used for cantilever support. Although not shown in the drawing, two wind direction plates 7 can be attached to substantially the entire area of the air outlet 2 via the attachment plate 10 and the link 5 on the left and right outer sides of the air conditioner main body 1.

The horizontally long outlet 2 provided on the lower surface of the front part of the air conditioner main body 1 is provided with flaps 3 divided into two around the horizontal axis so that the installation angle θ1 can be adjusted in the front-rear direction X. Therefore, by rotating the flaps 3 and 3 to adjust the installation angle θ1 in the front-rear direction X, the conditioned air K blown from the outlet 2 of the air conditioner 1 is changed in the vertical direction Z. Then, the reaching distance L of the conditioned air K such as the cold air K1 or the warm air K2 is selected. Further, since a plurality of louvers 4 are provided in the air outlet 2 so that the installation angle θ2 can be displaced in the left-right direction Y around the vertical axis, the louver 4 is displaced in the left-right direction Y, etc. The point of performing airflow control such as changing the direction of K blowing in the left-right direction Y is the same as the conventional operation.

However, in the present embodiment, one end 5 a of the link 5 is attached to the outside of the air conditioner body 1 via the fixing portion 6 so as to change the angle θ 3 as described above, and the other end of the link 5 is provided. Since the wind direction plate 7 is attached to the link 5 via the angle adjusting means 8 at 5b, one end 5a is attached to the outside of the air conditioner body 1 via the fixing portion 6 when cooling is performed in summer or the like.

A cylindrical sleeve 13 having one end 13a fitted to the link 5 is fitted into the outer periphery of the small-diameter threaded cylindrical portion 12 having a protruding and expandable split groove 12a in the longitudinal direction I of the outer periphery. A screw 14 is rotatably supported in the screw 13, and a set screw 14 is further screwed into the screw 12 to form a tapered portion 14 b provided on the outer periphery of the lower surface of the seat of the screw head 14 a of the set screw 14. Since the screw portion 12 is forcibly expanded in the circumferential direction and is pressed against the inner periphery of the sleeve 13, the screwing degree of the set screw 14 into the screw portion 12 is adjusted to thereby adjust the screw portion 12. The degree of pressure contact with the sleeve 13 can be increased or decreased. 8 can be easily adjusted to the desired angle θ4 with respect to the link 5, and the angle adjusting means 8 is provided with the split groove 12′a as shown in FIG.

You can also make it.

For example, when heating is performed in winter or the like, the angle θ 3 of the link 5 to which the one end 5 a is attached to the outside of the air conditioner main body 1 via the fixing portion 6 is similarly changed with respect to the attachment plate 10. When the wind direction plate 7 provided at the other end 5b of the link 5 via the angle adjusting means 8 is changed downward by the above-described operation and handling as shown in FIG. 6, the specific gravity blown out from the outlet 2 becomes normal. The warm air K2, which is lighter than the room air and easily accumulates near the ceiling of the room, is blown out from the air outlet 2 and hits the wind direction plate 7 so that the blowing direction is changed downward. The air flows smoothly from the upper part of the room to the lower part of the room, so that convection is performed smoothly, and the room can be efficiently heated to a desired set temperature in a short time. In this way, by changing the wind direction plate 7 upward or downward due to the specific gravity of the conditioned air K such as the cold air K1 or the warm air K2, the convection of the cold air K1 or the warm air K2 is smoothly performed in the room, Cooling or heating can be performed efficiently.
