Abstract

PURPOSE:To reduce the deteriorating rate of resistance and amount of airflow at a time when the airflow hits left and right airflow deflecting vanes and to permit a large deflecting angle by a method wherein a plurality of left and right airflow deflecting vanes, formed by a plurality of plane sections and the ends thereof at the downstream side of airflow are bent into directions getting away from the center of a blow-off grille, are attached to the inside of the blow-off grille. CONSTITUTION:An airflow deflecting device is formed by a method wherein at least one end of left and right airflow deflecting vanes 9 of chevron type which is formed by two planes is incorporated rotatably into the blow-off port 3a of a blow-off grille 3. Even when airflow, sent from a fan (upstream side of airflow) hits the left and right airflow deflecting vanes 9 in the blow-off port 3a and is deflected to left and right forcibly, the resistance of the vanes is small and the airflow flows into a living space (downstream side) while adhering to the deflecting vanes 9 or left and right walls 3b, therefore, the deterioration of amount of airflow can be improved remarkably.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wind direction deflection device for deflecting the blowing direction of an air conditioner.

2. Description of the Related Art Conventionally, this type of air conditioner has been constructed as shown in FIG.

In the figure, reference numeral 1 denotes a frame main body of the indoor unit, in which a front grill 2 having an inlet 2a and an outlet grill 3 having an outlet 3a are housed. 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 2& and the air outlet 3a, and inside thereof a heat exchanger 5 and a blower 6 constituting a refrigeration cycle are installed. is installed. Reference numeral 7 denotes a vertical wind deflection blade whose both ends are incorporated into the side wall of the outlet grille 3, and 8 denotes a plurality of left and right wind direction deflection blades which have at least one end incorporated inside the outlet grille 3. As shown, it is made of a flat plate.

However, with such a structure, if the air passing through the air outlet 3a is largely deflected to the left or right in order to send air to a wide area in the living space and provide air conditioning and heating, However, if the indoor air volume decreases, the air conditioner's performance will decrease and the input will increase due to the refrigeration cycle, so there is a problem that the deflection angle cannot be changed or increased.

As shown in Fig. 3, the wind passing through the air outlet 3a in the air outlet grille 3 from the windward side hits the flat left/right wind direction deflecting blade 8 and is forcibly deflected to the left and right, so there is no resistance. This is because the air volume increases and the air volume decreases. Therefore, the present invention is designed to reduce the resistance when the wind hits the left and right wind deflection blades 8 when the wind is largely deflected to the left and right, thereby reducing the rate of decrease in air volume and allowing a large deflection angle.

Means for Solving the Problems and Means for Solving the Problems The above-mentioned means for solving the problems is provided in the above-mentioned outlet grille with a plurality of planar parts, the leeward end of which is bent in a direction away from the center of the outlet grille. A plurality of left and right wind direction deflection vanes are installed.

For production The effect of this technical means is as follows.

In other words, when the left and right wind deflection blades are bent to deflect the wind, the wind passing through the outlet attaches to the left and right wind deflection blades,
By reducing the resistance when passing through, the rate of decrease in air volume becomes smaller, and the wind can be deflected to the left or right.

Embodiment Hereinafter, one embodiment of the final F#1 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 the dog-shaped left and right wind direction deflecting blades 9 formed by two flat parts are rotated. In this embodiment, the left and right end walls 3bI/'i of the outlet grille 3 are formed of curved portions that widen from side to side as shown in the figure.

As a concrete illustration of the effects of the above configuration, FIG. 4 shows experimental results of the wind deflection angle and air volume reduction rate in the case of the conventional peeling example.

As is clear from this result, even when the wind sent from the blower (on the windward side) hits the left and right wind direction deflection blades 9 in the outlet 3a and is forcibly deflected to the left and right, the resistance is small;
It adheres to the left and right wind direction deflection blades 9 and the left and right walls 3b of the outlet grille 3, and flows toward the living space (downwind side), thereby greatly improving the reduction in air volume.

Further, in this embodiment, the left and right wind direction deflecting blades 9 are formed of two flat parts, but the same effect can be obtained even if the left and right wind direction deflecting blades 9 are formed of a plurality of flat parts.

As described above, if the left and right wind direction deflecting blades of the present invention are used,
Even when the wind is largely deflected to the left or right, the rate of decrease in air volume can be reduced, which significantly improves the angle of deflection of the wind to the left or right, which had been limited in air conditioners up until now. It is also possible to prevent a decrease in the performance of the harmonizer, and it is possible to improve comfort in the living space.
