Abstract

PURPOSE:To enable to multidirectionally change the direction of air flow in any direction by a structure wherein an angularly adjustable horizontal direction deflector, on the top surface and the underside surface of which angularly adjustable straightening vanes are provided independently with each other, is provided in the interior of the discharge port of an air conditioner. CONSTITUTION:The air past through a heat exchanger is changed its flow direction by angularly adjusting a horizontal direction deflector 14a vertically. In this case, the pivoting angle of the horizontal direction deflector 14a is regulated so as not to shut off discharging air. In addition, the air flow direction can be changed leftwards and rightwards by angularly adjusting leftward and rightward direction deflectors 14f and 14g serving as straightening vanes simultaneously leftwards and rightwards. Furthermore, because the leftward and rightward direction deflectors 14f and 14g are respectively and independently composed on the top surface and on the underside surface of the horizontal direction deflector 14a, the direction of air flow on the top surface and on the underside surface of the horizontal direction deflector 14a can be separately changed leftwards and rightwards.

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.

2. Description of the Related Art Conventional Structures and Problems Conventionally, wind direction changing devices for ceiling-mounted air conditioners and the like are generally shown in FIGS. 1, 2, and 3. That is, this figure shows the main body of the air conditioner, and the discharge port BL is formed on the front side.

The front surface of the discharge port is equipped with a vertical, horizontal, and horizontal wind direction changing plate C whose left and right ends are rotatably supported. A large number of dogleg-shaped auxiliary vertical wings d integrally molded from synthetic resin are provided at right angles at regular intervals on both upper and lower surfaces of the lower left and right wind direction change plate C.

In this configuration, the direction of the wake 11 of the auxiliary vertical blade d is set to the air conditioner main body a with the lower left and right wind direction change plate C being horizontal.
If the direction is perpendicular to the direction, the wind direction will be in front of you. As shown in Figure 3, the wind direction can be changed to the right or left by rotating either one of them 1000 times, and if both the upper, lower, left, and right wind direction plates C are rotated by 18QO, the entire flow can be changed in the left and right direction over a wide range. .

With this configuration, the wind direction is directed vertically and horizontally, but the vertical and horizontal wind direction changing plate C must be adjusted by a rotation angle of 3600 degrees, and when set in the vertical position, it cuts off a part of the discharge air flow. There was a drawback that it could be stored away. Further, the overall discharge air flow cannot be changed to the left or right.

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 blocking the discharged airflow when the air conditioner is tilted. 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, so that the air direction can be adjusted vertically as a whole without blocking the discharged air. This provides the effect of changing the wind direction from side to side.

In the explanatory diagram of the embodiment, 1 is an air conditioner main body, and the inside of this 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 is the suction port 5f! : It has a fan casing 6 in which a sirocco fan (not shown) is housed, and a motor 7 for driving the fan. Inside the heat exchange chamber 4, there is a heat exchanger 10 attached to the side plate 8.9. It has an auxiliary heater 11 and a drain pan 12, and the front part has a discharge port 1.
3, and this 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 11III is inserted into the side plate 9, so that the angle can be adjusted at a predetermined angle (for example, an angle within 1600 degrees). A plurality of the wind direction changing devices 14 are arranged at right angles on the upper and lower surfaces of the horizontal wind direction changing plate 14a at appropriate intervals.

14C, which are integrally molded from synthetic resin. The rising sides 14b and 14cK are the hinge 14
d and 14e are provided, and left and right wind direction changing plates 14f and 14g1 are inserted into the hinges 14d and 14e, respectively, so that the angle can be adjusted. These rising sides 14b and 14c and left and right wind direction changing plates 14f and 14q constitute a current plate. The Muni right wind direction history plates 14f and 14g are provided with interlocking rods 14h and 141, respectively, and a plurality of left and right wind direction changing plates 14f.
, 14g are linked at the same time.

In this configuration, when the wind passing through the heat exchanger 1o passes through the wind direction changing device 14, the horizontal wind direction changing plate 14ai
It changes in the vertical direction by adjusting the angle 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 14q as current plates in the left and right direction, the overall wind can be changed in the left and right direction. In addition, the left and right wind direction change plate 14
Since f and 14g are formed independently on the upper and lower surfaces of the horizontal wind direction changing plate 14a, it is possible to change the wind in the left and right directions independently on the upper and lower surfaces of the horizontal wind direction changing plate 14a.

Explanatory power that exceeds the effects of the invention As is clear, according to the present invention, the wind direction can be changed minutely in all directions by the angle-adjustable rectifying plates provided independently on the upper and lower surfaces of the horizontal wind direction-changing plate. In addition, it is possible to move vertically, horizontally, vertically, without blocking part of the discharge airflow depending on the rotational position as in the conventional example.
Moreover, the entire wind direction can be changed in the same direction.
