Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a wind direction changing device installed inside a discharge port of an air conditioner (hereinafter referred to as an air conditioner) to guide discharged air in any direction, up, down, left or right. be.

Conventional Structures and Their Problems Conventionally, as a wind direction changing device for a ceiling-mounted air conditioner, the devices shown in FIGS. 1, 2, and 3 are common. That is, in this figure, a indicates the air conditioner main body, and a discharge port b is formed on the front surface.
The front surface of the discharge port b is provided with a pair of left and right wind direction change plates C, C whose right and left ends are rotatably supported. A large number of dogleg-shaped auxiliary vertical blades d integrally molded from synthetic resin are provided at right angles at regular intervals on both upper and lower surfaces of the upper, lower, left, and right wind direction changing plates c.

In this configuration, the vertical and horizontal wind direction changing plate c
If the direction of the wake side of the auxiliary vertical blade d is perpendicular to the air conditioner main body a, assuming that the angle is horizontal, the wind direction is directed to the front. As shown in Figure 3, you can change the wind direction to the right or left by rotating either one of them by 180 degrees, and by rotating both the upper, lower, left, and right wind direction plates c by 180 degrees, you can change the overall wind direction in the left and right directions over a wide range. can.

According to the configuration, the wind direction changing plate C rotates the left wind direction changing plate by 180 degrees and also rotates the right wind direction changing plate when changing leftward discharge to rightward discharge as shown in FIG. 3, for example. It is necessary to rotate it 180 degrees, a total of 360 degrees, and when it is set in the vertical position (rotated 90 degrees from the state shown in Figure 3),
There was a drawback that part of the discharged air was blocked. Further, the angle of the wind direction changing plate C could not be adjusted so that the air was discharged in the same direction on both the left and right sides. That is, in FIG. 3, the wind direction changing plate on the left side could not change the discharge air flow to the right, and the right side wind direction changing plate could not change the discharge air flow to the left.

Purpose of the Invention The present invention solves the above-mentioned drawbacks and provides a wind direction changing device that can adjust the overall direction of the discharged airflow to the left or right without interrupting the discharged airflow in an air conditioner. The purpose is to

Structure of the Invention In order to achieve this object, the present invention provides angle-adjustable rectifying plates on the upper and lower surfaces of a horizontal wind direction changing plate that can be rotated at a predetermined angle, thereby eliminating the need to block the discharged air and to prevent This provides the effect of changing the wind direction from side to side.

DESCRIPTION OF THE EMBODIMENTS In the figure, reference numeral 1 denotes an air conditioner main body, and the inside of the main body 1 is divided into a ventilation chamber 3 and a heat exchange chamber 4 by a partition plate 2. The lower surface of the ventilation chamber 3 constitutes a suction port 5, and has a fan casing 6 containing a Sirotskov fan (not shown) therein, and a motor 7 for driving the fan. The heat exchange chamber 4 has a heat exchanger 10 attached to side plates 8 and 9, an auxiliary heater 11, and a drain pan 12, and the front part has a discharge port 13.
The discharge port 13 is equipped with a wind direction changing device 14 whose angle can be adjusted. One shaft of the wind direction changing device 14 is inserted into the side plate 8, and the other shaft is inserted into the side plate 9, so that the angle can be adjusted at a predetermined angle (for example, an angle within ±60°). The wind direction changing device 14 is provided with a plurality of right-angled uprights 14b and 14c at appropriate intervals on the upper and lower surfaces of the horizontal wind direction changing plate 14a, and these are integrally molded from synthetic resin. The rising side 14b,
14c is provided with hinges 14d and 14e, and the left and right wind direction changing plates 1 are attached to the hinges 14d and 14e, respectively.
4f and 14g are inserted and installed, and the angle can be adjusted. The rising sides 14b and 14c and the left and right wind direction changing plates 14f and 14g constitute a current plate. The left and right wind direction changing plates 14f and 14g are provided with interlocking rods 14h and 14i, respectively, for simultaneously interlocking a plurality of left and right wind direction changing plates 14f and 14g.

In this configuration, when the wind passing through the heat exchanger 10 passes through the wind direction changing device 14, it changes in the vertical direction by adjusting the angle of the horizontal wind direction changing plate 14a in the vertical direction. In this case, since the rotation angle of the horizontal wind direction changing plate 14a is regulated, the discharge air is not blocked. By simultaneously adjusting the angle of the left and right wind direction changing plates 14f and 14g, which serve as current plates, in the left and right directions, the overall wind can be changed in the left and right directions. In addition, since the left and right wind direction changing plates 14f and 14g are configured independently on the upper and lower surfaces of the horizontal wind direction changing plate 14a, it is possible to individually change the wind direction to the left and right on the upper and lower surfaces of the horizontal wind direction changing plate 14a. It is.

Effects of the Invention As is clear from the above description, according to the present invention, the angle-adjustable rectifying plates provided independently on the upper and lower surfaces of the horizontal wind direction-changing plate, which can be adjusted within a predetermined angle range, allow fine-grained air flow in all directions. Moreover, the airflow direction can be changed vertically, horizontally, and in the same direction without blocking a part of the discharged airflow by changing the rotational position as in the conventional example.
