Description

Detailed Description of the Invention The present invention relates to a blowout direction changing device for an air conditioner, and by periodically changing the blowout angle independently in the vertical and horizontal directions, comfortable air conditioning can be achieved over a wide range and with less indoor temperature distribution. It is an attempt to provide space.

Most conventional air conditioners with periodic air direction change devices change the air direction, but only in the vertical or horizontal direction. There were problems as shown.

1. When periodically changing the wind direction only in the horizontal direction, this changing device is generally done by arranging vertical vanes that oscillate at the outlet, but the trajectory of the conditioned air during the oscillating movement is only on the same horizontal plane. Therefore, the area located in the trajectory of the conditioned air will be cold when air conditioned and hot when heated, resulting in poor indoor temperature distribution.

2. When periodically changing the wind direction only in the vertical direction, this is done using a swinging horizontal vane or a fluid blowing element as a device to change the direction in the vertical direction, but in this case, as in 1. Places located in this orbit will be colder with air conditioning, hotter with heating, and the indoor temperature distribution will be worse.

Moreover, in this case, since the direction of the air is changed from the outlet in a vertical direction, the wind from the outlet blows directly into the living area, and the wind hits the human body, causing discomfort especially during heating. In addition to the above, there is also a device that rotates a blow-off grill to blow air in the circumferential direction of the outlet, and a device that has multiple disc-shaped deflection blades at an angle to the rotating shaft and changes the direction of the air by rotating the rotating shaft. However, since these systems change the wind direction by rotating fixed blades, the rotation trajectory of the conditioned air remains constant, and the width and angle of change cannot be changed freely.

Therefore, depending on the installation position of the air conditioner, wind may blow into the living area or the conditioned air may hit the wall, causing not only discomfort but also energy loss. The present invention solves the above-mentioned drawbacks of the prior art by performing periodic wind direction changes simultaneously in the horizontal and vertical directions.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 6. In Fig. 1, numeral 1 denotes a main body that houses a heat exchanger 2, a blower 3, etc., and a suction port 4 at the upper front of the main body.
An air outlet 5 is provided at the bottom.

The air outlet 5 is provided with a horizontal changing device 6 for periodically changing the blowing angle in the horizontal direction, and a vertical changing device 7 for periodically changing the blowing angle in the vertical direction. 8 is an impeller provided in the blower 3 via a fan motor 9, and 10 is a drain receiver.

Figure 2 shows horizontal devices 6, 11, 12 and vertical change devices 7, 1.
7, 18 and periodic operating devices 13-16, 19-22.

In the figure, 11 is a vertical vane vertically arranged in parallel at the air outlet 5 so as to be rotatable around a pin 12; 13 is a low-speed motor;
4 is an arm that transmits the rotation of the low-speed motor 3 to the connecting rod 15; the arm 14 and the connecting rod 15 constitute a crank mechanism that causes the shaft 16 to reciprocate and swing the vertical vane 11. Reference numeral 17 indicates a machine vane which is arranged in parallel to the outlet 5 so as to be rotatable about a pin 18, 19 is a low speed motor, a two-way arm, 21 is a connecting rod, and 22 is a shaft.

The operation is the same as the vertical vane. Figure 3 shows the horizontal change device 6
This is the configuration of a horizontal angle setting device and a vertical angle setting device that set the change angle of the vertical change device 7. In the figure, the arms 14, 20' are connected to holes a to d for changing the width of the wind direction. The shafts 16 and 22 are provided with holes e to i for changing the center angle for changing the wind direction. Connected bran 15, 21
Pins 23 and 24 are provided at both ends of the hole, and the pin 23 is inserted into one of the holes a to d. In this case, the radius of rotation becomes smaller closer to the rotation axis of the low-speed motors 3, 19, so the width of the wind direction change becomes smaller. The pin 24 is inserted into one of the holes e to i. In this case, the center angle of the air direction change for hole g is the center with respect to the air outlet, the center angle for holes f and e is on the X direction in the figure, and the center angle for holes h and i is on the Y side in the figure.
change direction. 26 is a pin.

In the above configuration, the low speed motor 3 of the horizontal change device 6
When the rotation speed of the low-speed motor 9 of the vertical change device 7 is the same, and when the rotation speed of the low-speed motor 3 is set to four times the rotation speed of the low-speed motor 19, the wind direction change width and the center angle of the wind direction change are changed. Three types of blowout operations will be explained below.
1 When the rotational speeds of the low-speed motor 13 and the low-speed motor 19 are the same.

If the wind direction is changed simultaneously in the horizontal and vertical directions while keeping the rotation speed the same, the trajectory will be as shown in Figure 4.

In FIG. 4, the air conditioner main body 1 is installed at the center of the upper part of the wall 26.

When the low-speed motors 13 and 19 start rotating, the air conditioner blows out in 7 directions initially, the horizontal change device starts to change the wind direction to the right, and the vertical change device starts to change the wind direction to the bottom. . Therefore, the composite wind direction changes from the Iweo direction. When the horizontal position is reached, the horizontal change device moves in the opposite direction to change the wind direction to the left. When it reaches the 7th position, the vertical change device changes the wind direction to the upper side, moving in the direction of Kekosa, and the horizontal change device changes the wind direction to the right side again.
direction and go around once.

After that, the wind direction changes as it repeats this process, drawing an orbit. 2 When the number of rotations of the low-speed motor 13 is set to four times the number of rotations of the low-speed motor 19.

In this case, the trajectory will be zigzag as shown in FIG.

This is because the vertical wind direction changes and the horizontal wind direction goes back and forth four times, so if you start changing the wind direction from the F direction in Figure 5, it will trace a zigzag trajectory in the direction of the E-W direction and return to the F position again. Changes are made. 3. When the rotation speeds of the low-speed motor 13 and the low-speed motor 19 are the same, and the wind direction change width and the center angle of the wind direction change are changed.

In FIG. 6, the air conditioner main body 1 is installed at the upper left corner of the wall 26.

The trajectory of the conditioned air is circular and the trajectory is the same as in case 1, but since the air conditioner body 1 is installed at the upper left corner of the wall, the center angle for changing the wind direction is on the left side of the room. Put it away. Therefore, the center angle adjustment hole e~ of the horizontal adjustment device 6
Select the i hole of i and insert the pin 24 of the connecting twill 15. or,
In order to reduce the vertical wind direction change width, select holes a of the wind direction change width variable holes a to d of the vertical change device 7, and insert the pin 23 of the connecting rod 21. Therefore, the center angle of the horizontal direction change is the center of the room, and the vertical direction change width is small. Therefore, if you start changing the wind direction from position A shown in Fig. 6, the wind direction will move in the same direction as in case 1, forming a conical trajectory. As described above, according to the present invention, the wind direction change period in the horizontal and vertical directions can be freely changed, and the angle and width can also be changed.

Therefore, conditioned air can be supplied to the entire room regardless of the installation position of the air conditioner, and the temperature distribution in the room can be made uniform. Furthermore, during heating, by making the horizontal and vertical wind direction changing cycles the same and making the hot air trajectory conical, the residential castle is enveloped with warm air, providing a soft heating sensation without making residents feel uncomfortable. can give. During cooling, by setting a difference between the horizontal and vertical wind direction change cycles and creating a zigzag trajectory, the air can be sent throughout the room, providing cooling with the added cooling effect of the wind.
