Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a wind direction changing device for an air conditioner.

BACKGROUND ART Conventionally, this type of air conditioner has had a configuration as shown in FIG.

In the figure, reference numeral 1 denotes a frame main body of an indoor unit, to which a front grill 2 having an inlet 2a and an outlet grill 3 having an outlet 3a are attached. Reference numeral 4 denotes a ventilation passage formed between the underframe main body 1 and the front grille 2, which communicates with the suction port 2a and the air outlet 3a, and inside thereof a heat exchanger 5 and a blower 6 constituting a refrigeration cycle are installed. It is arranged.
Reference numeral 7 indicates a vertical wind direction changing blade whose both ends are incorporated in the side wall of the outlet grille 3, and 8 indicates a plurality of left and right air direction changing blades which have at least one end incorporated inside the outlet grille 3, and are also shown in FIG. It is formed from a flat plate.

Problems to be Solved by the Invention However, with such a structure, the air outlet 3
When the air passing through a is deflected left and right to a large extent, the air volume decreases significantly, and in terms of the refrigeration cycle, if the indoor air volume decreases, the capacity decreases and the input increases, so there was a problem that the deflection angle could not be made very large.

This is because, as shown in Fig. 3, the wind passing through the outlet 3a in the outlet grille 3 from the windward side hits the flat left/right wind direction changing blade 8 and is forcibly deflected to the left and right, resulting in a large resistance. This was because the air volume decreased.

Therefore, the present invention has the advantage that even if the wind is largely deflected to the left or right,
This prevents the wind from being reduced when it hits the left and right wind direction changing blades 8, thereby reducing the amount of reduction and making it possible to increase the deflection angle.

Means for Solving the Problems The means for solving the above problems is to attach a plurality of curved right and left wind direction changing vanes, each of which has at least one end incorporated inside the above-mentioned blow-off grille.

Effect The effect of this technical means is as follows.

That is, when deflecting the wind by bending the left and right wind direction changing blades, in the present invention, the wind passing through the outlet attaches to the left and right wind direction changing blades, thereby reducing the loss of air volume and making it possible to largely deflect the wind to the left and right. It is.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, at least one end is incorporated into the air outlet 3a in the air outlet grille 3, and a plurality of arcuate left and right wind direction changing blades 9 formed by curved portions are rotatably attached. In this embodiment, the left and right end walls 3b of the outlet grille 3 are formed of curved portions that widen left and right in accordance with the direction of the curved portions of the left and right wind direction changing blades 9.

In order to specifically demonstrate the effects of the present invention, we conducted an experiment to investigate the relationship between the wind deflection angle and the air volume reduction rate in the conventional example and the example, and the results are shown in Figure 4. .

As is clear from this result, even when the wind sent from the blower (windward side) hits the left/right wind direction changing blade 9 in the outlet 3a and is forcibly deflected to the left or right, the resistance is small, and the left/right wind direction changing blade 9 It adheres to the left and right walls 3b of the blow-off grille 3 and flows to the leeward side, which greatly improves the reduction in air volume.

Effects of the Invention As described above, by using the left and right wind direction deflection vanes of the present invention, even when the wind is deflected greatly to the left and right, the reduction in air volume can be reduced. The deflection angle to the left and right can be significantly improved.
