  However, in the conventional configuration, the rotation axis of the upper and lower flaps is not near the center of the upper and lower flaps, but is biased toward the upper end or lower end of the blowout port. Rectification could not be completed, and there was a problem of reducing the effect of changing the wind direction.

  In the example of Patent Document 1, since the rotation axis of the upper and lower flaps is closer to the upper end side of the blowout port, the blowout air on the lower end side of the blowout port even when the upper and lower flaps are directed upward, such as when the main flow of the blowout air is downward. May not be fully rectified. Especially in the cooling operation, when the amount of air flow is small at the start of heating, the cooled blown wind has a large specific gravity and most passes through the lower part of the blowout outlet, so it becomes difficult to blow up the blown wind upward. The wind direction changing effect was reduced.

  The present invention solves the above-described conventional problems, and an object thereof is to provide a wind direction change device for an air conditioner that rectifies blown wind that cannot be rectified by only the upper and lower flaps and improves the wind direction change effect. .

  In order to solve the above-described conventional problems, the air conditioner wind direction changing device according to the present invention includes a connecting bar for left and right flaps for changing the wind direction to the left and right substantially parallel to the upper and lower flaps, and a cross section of the connecting bar is substantially omitted. It has a wing shape.

  As a result, the connecting beam can be used as a substitute for the blades to rectify the blown wind that cannot be rectified only by the upper and lower flaps, thereby improving the wind direction changing effect.

The air conditioner wind direction changing device of the present invention provides air conditioned air that can efficiently air-condition and respond quickly to user requests by rectifying the blown air and improving the wind direction changing effect. can do.

  In the second invention, in particular, the outlet is divided into two upper and lower regions on a virtual plane passing through the center between the upper and lower ends of the outlet and the pivot axis center of the connecting bar and the upper and lower flaps of the first invention. In some cases, the connecting bars rectify the blown wind and can improve the effect of changing the wind direction by providing them in different areas.

  In the third invention, in particular, the connecting beam of the first or second invention is provided on the upstream side of the blowing air from the central portion of the left and right blades with respect to the flow direction of the blowing air. It can rectify and the wind direction changing effect can be further improved.

  In the fourth invention, in particular, the width in the flow direction of the blowing air of the connecting bar according to any one of the first to third inventions is set to be at least 1/4 or more of the width in the flow direction of the blowing air of the upper and lower flaps. The connecting beam rectifies the blown wind, and the wind direction changing effect can be further improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a longitudinal sectional view of a main part of an air conditioner according to a first embodiment of the present invention.

  In FIG. 1, a main body 1 of an air conditioner includes a fan case 2, a stabilizer 3, and a suction grill 4 to form a ventilation passage 6. The indoor air 5 is sucked from the suction grill 4 by a blower fan 7 provided in the blower passage 6 and is heat-exchanged by the heat exchanger 8 to be formed by the fan case 2 and the stabilizer 3 on the downstream side of the blower passage 6. 6, the air is blown into the room from the air outlet 9 via the wind direction changing device main body 10.

  FIG. 2 is a plan view of the left and right flaps in the first embodiment of the present invention, and FIG. 3 is a sectional view of the left and right flaps in the first embodiment of the present invention.

  2 and 3, the left and right flaps 12 support a plurality of left and right blades 13, a connecting bar 15 that connects them, and a plurality of left and right blades 13 movably supported and attached to the upper and lower flaps 11 so as to be rotatable. It is comprised with the crosspiece 14.

  The left and right blades 13 are rotatably supported and fixed to a blade shaft 17 that allows the left and right blades 13 to be fitted in fitting holes 16 provided in the support rails 14 so as to be movable left and right, and a fixing hole 18 provided in the connecting rail 15. A fixed shaft 19 is provided. The plurality of left and right blades 13 are coupled to the support bar 14 and the connecting bar 15 by the blade shaft 17 and the fixed shaft 19, respectively. With such a structure, a plurality of blades can be directed in the same direction by changing the direction of some of the left and right blades, and the wind direction can be adjusted in the left-right direction.

  The left and right flaps 12 are moved upstream or downstream in the blowing direction in conjunction with the vertical rotation of the upper and lower flaps 11.

  The connecting bar 15 is disposed substantially parallel to the upper and lower flaps 11, and the cross section of the connecting bar 15 has a substantially wing shape. In addition, while the rotation axis of the upper and lower flaps 11 is closer to the upper end side of the air outlet 9, the connecting bar 15 is closer to the lower end side of the air outlet 9 than the center of the left and right blades 13 with respect to the vertical direction when viewed from the front. It is provided on the upstream side of the blowing air from the central part of the left and right blades 13 with respect to the flow direction of the blowing air. Furthermore, the width of the connecting bar 15 in the flow direction of the blown air is at least 1/4 of the width of the upper and lower flaps 11 in the flow direction of the blown air.

  For the left and right flaps configured as described above, the connecting bars can substitute for the blades to rectify the blown wind that cannot be rectified by only the upper and lower flaps, thereby improving the wind direction changing effect, thereby efficiently performing air conditioning. It is possible to provide an air conditioner that can respond more quickly to user requests.

  In particular, in response to the recent demand for thinner indoor units, the mainstream of the blown air tends to be downward due to the increase in the gradient of the fan case due to the thinner thickness. Because the cooled blown wind has a large specific gravity and most passes through the lower part of the blowout port, it is possible to rectify the blown wind and improve the wind direction changing effect when it is difficult to blow up the blown wind upward it can.

  Further, when the rotation axis of the upper and lower flaps 11 of the present embodiment is closer to the lower end side of the air outlet 9, the connecting bar 15 is from the center of the left and right blades 13 in the vertical direction when viewed from the front. By providing it on the upper end side of the air outlet 9, it is possible to efficiently perform air conditioning by improving the wind direction change effect by rectifying the blowing wind that cannot be rectified by the upper and lower flaps alone, by using the connecting bar as a substitute for the blades. Therefore, it is possible to provide an air conditioner that can respond quickly to the user's request.

  As described above, in the air conditioner wind direction changing device according to the present invention, the connecting beam is used as a substitute for the blades to rectify the blown wind that cannot be rectified only by the upper and lower flaps, thereby improving the wind direction changing effect. Therefore, it can be applied to uses such as a blower having upper and lower flaps, a dehumidifier, and a fan heater.
