Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a wind direction changing device installed inside the discharge port of an air conditioner.

Conventional structure and its problems Conventionally, the wind direction changing device in a ceiling-suspended air conditioner (hereinafter referred to as an air conditioner) is as shown in Figures 1 and 2.
The one shown in Fig. 3 is 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 equipped with a discharge grill c, and the inner surface of the discharge port b has a shaft f rotated by an electric motor d and a wind direction changing plate e provided at an appropriate interval and angle with respect to the shaft f. However, the wind direction was changed by changing the rotational position of the electric motor d. In this configuration, when the wind direction is changed as described above, the movement of the discharged air due to the change in the wind direction draws approximately a horizontal figure 8 as shown in Figure 1, so it is possible to concentrate the air in the downward direction, which is required especially during heating operation, and also to It was not possible to change the wind direction continuously in the left and right directions in order to disperse and discharge the air. In other words, only intermittent discharge was possible at both ends of the discharge port.

Purpose of the invention The present invention eliminates the above-mentioned drawbacks and allows the air conditioner to change the wind direction in the left and right directions while also adjusting the wind direction in the vertical direction.In particular, when changing the wind direction in the left and right directions, the air is discharged intermittently at both ends of the discharge port. To provide a wind direction changing device capable of obtaining a continuous discharge air flow rather than a single current, and capable of sending the air to a wider angle.

Structure of the invention In order to achieve this purpose, in addition to changing the wind direction by rotating it with a conventional electric motor, a rotatable horizontal wind direction changing plate is provided on the front side of the horizontal wind direction changing plate. A vertical auxiliary wind direction changing plate is provided to change the direction of the discharged air vertically and horizontally, and the auxiliary wind direction changing plate provides a continuous discharge air flow at both ends of the discharge port.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an air conditioner main body, and inside this main body 1 there is a fan casing 2 in which a Sirotskov fan (not shown) is installed, a ventilation chamber 4 having a motor 3 for driving the fan, and a side plate 6 through a partition plate 5. ，
Heat exchanger 8 attached to 7, auxiliary heater 9, drain pan 10, rotatable wind direction changing plate 11, horizontal wind direction changing plate 1 which is also rotatable (angle adjustable)
2. Auxiliary wind direction changing plate 1 provided on this wind direction plate 12
3, 13' and a discharge grille 14 constitute a heat exchange chamber 15 and a discharge port 16. The wind direction changing plates 11 are approximately circular and are attached at appropriate angles to the shaft 11a and at appropriate intervals. One end of the shaft 11a is inserted into a bearing 17 fixed to one side plate 7, and the other end is inserted and connected to the rotating shaft of an electric motor 18 fixed to the other side plate 6, so that the shaft 11a is interlocked with the rotational movement of the electric motor 18. The wind direction changing plate 11 rotates to change the wind direction in the left and right directions. As shown in FIGS. 6 and 7, the horizontal wind direction changing plate 12 located on the leeward side of the wind direction changing plate 11 has one end of its shaft 12a inserted into the side plate 6, and the other end inserted into the side plate 7. It can be inserted and rotated freely to change the direction of the discharged air flow up and down. Further, at both ends of the horizontal wind direction changing plate 12, there are vertical auxiliary wind direction changing plates 13, 13' each having an appropriate angle so as to provide a wide range of air flow relative to the discharge direction. This auxiliary wind direction changing plate 13 is made up of a fixed part 13a that is bent into a substantially U-shape and fixed to the back of the horizontal wind direction plate 12 by spot welding or the like, and rising pieces 13b and 13c that are parallel to each other on both sides of this fixed part 13a. The rising piece 13b,
13c is fixed at a predetermined angle so that the discharged air spreads to both sides of the discharge port 16, as described above. Further, the length of the rising pieces 13b, 13c in the flow direction of discharged air is set to such an extent that they do not protrude from the horizontal wind direction changing plate 12 when fixed at a predetermined angle, and the fixed portion of the rising pieces 13b, 13c The front part that is not continuous with 13a can be bent, so that the angle mentioned above can be changed in the front part. In other words, the rising piece 1 shown in FIG.
By bending the dimension H of 3b and 13c to an arbitrary angle, the wind direction change angle can be changed.

In this configuration, by rotating the wind direction changing plate 11, the direction of the discharged air is changed in a substantially figure-eight shape as shown in the conventional example shown in FIG. The wind direction is also changed continuously from left to right. In addition, the auxiliary wind direction change plate 13,1
3', the flow of discharged air at both ends of the discharge port 16 is limited to a portion of both ends of the discharge port 16a, that is, as shown by arrows A and B in FIG.
A continuous flow is always obtained regardless of the movement of the In other words, while wide angle discharge is possible on both sides of the discharge port 16, not only an intermittent discharge flow but also a continuous discharge flow can be obtained.

Effects of the invention As is clear from the above explanation, according to the present invention, it is possible to change the wind direction in the specified direction in the vertical direction while changing the wind direction in the horizontal direction.
Further, part of the discharged air at both ends of the discharge port can be continuously discharged by the auxiliary wind direction changing plate. Furthermore, by bending the front portion of the auxiliary wind direction changing plate, the position of the continuous discharge flow can be changed arbitrarily.
