Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a comfortable and wide-ranging air-conditioned space by periodically changing the blowing wind speed and blowing direction.

Conventionally, there were many air conditioners with a swing mechanism, but because the speed of the blowing air was constant, strong winds could blow into the center of the living area, causing extreme discomfort to the occupants.

In particular, when temperature distribution tends to occur vertically and horizontally indoors, such as during heating, increasing the wind speed and oscillating the wind direction is effective in making the indoor temperature distribution uniform. Not only does the strong wind that hits you make you feel uncomfortable, but the cooling effect of the wind can even make you feel cold.

However, if the wind speed is simply reduced and the wind direction is oscillated, the strong wind will not hit the human body, but the distance that the conditioned air will reach will be shortened, and the indoor temperature distribution will deteriorate rapidly.

Therefore, the feet become cold and the head becomes hot, causing discomfort.

Figure 1 shows a plan view of the interior of the room during a conventional swinging operation. It is an air conditioner.

2' indicates the indoor wall, 3' indicates the indoor living area, and 4' indicates the reach distance of the conditioned air.

As this figure clearly shows, strong winds blow into most of the residential areas.

Therefore, no matter where you are in the room, people who catch the wind feel uncomfortable.

When performing air conditioning over a wide area by oscillating the blowing direction as described above, the blowing wind speed must be increased, but if the blowing wind speed is strong, strong winds will blow into the living area, causing discomfort to the human body. I had given it away.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 2 to 5.

In Figure 2, 1 is an air outlet 2 at the top and an inlet 3 at the bottom.
The main body of the air conditioner is equipped with a blower 4 and a heat exchanger 5, and the outlet 2 is provided with a vertical vane 6 that can swing freely and a nozzle-shaped throttle lower that changes the area of the outlet.

Numeral 8 is a spring installed at the bottom of the aperture lower and acts to push the aperture opening upward, and 9 is a drain receiver.

3 and 4 show the operation of the vertical vane 6 and the aperture 07.

10 is a cam directly connected to the low-speed motor 11; 12 is a shaft connected to the cam 10 via a connecting rod 13; and the shaft 12 has a plurality of vertical vanes 6 arranged in parallel at the air outlet so as to be able to swing freely. It is connected.

This cam 10, low speed motor 11, shaft 12 and connecting rod 13 constitute a synchronizer.

Further, the cam 10 is located at the upper part of the aperture lower, and the cam 10
The diaphragm lower moves up and down twice for one rotation.

As shown in FIG. 4, the vertical vane 6 makes one reciprocation for one rotation of the cam.

In this case, when the vertical vane 6 is tilted to the left or right, the throttle lower moves upward and pinches the outlet area, and when the vertical vane is at the center, the throttle opening moves downward and the outlet area expands.

Therefore, when the airflow is blown out toward both ends of the air conditioner body 10, the wind speed is high, and when it is blown out in the front direction of the air conditioner body 1, the wind speed is slow.

FIG. 5 shows the distance reached at that time.

Reference numeral 14 indicates the wall of the air-conditioned room, reference numeral 15 indicates the living area of the room, and reference numeral 16 indicates the reach of the conditioned air blown out from the main body outlet while swinging.

As described above, according to the present invention, the wind speed of the conditioned air blown toward the indoor living area is slow, and the wind speed of the conditioned air blown toward both ends of the air conditioner body is fast.

Therefore, the following effects can be obtained.

■ The speed of the conditioned air blown into the center of the room is slow, so there is less unpleasant wind intruding into the living area.

■ The speed of the conditioned air blown out from both ends of the air conditioner is high, so the conditioned air circulates near the walls of the room, reducing the vertical and horizontal temperature distribution in the room, creating a comfortable air-conditioned feeling. .

■ Conditioned air flows along the walls of the room, so during heating, the temperature of the walls rises and the radiant heat from the walls creates a soft heating sensation.

Furthermore, the amount of cold air entering the room through the walls can be reduced.

During cooling, it is possible to reduce the unpleasant radiant heat generated by the outside temperature and the wall temperature, which tends to rise due to sunlight.

■ Since the blowing direction swings, the conditioned air can be distributed over a wide area in the room.

As described above, according to the present invention, by simultaneously periodically varying the wind speed and direction of the conditioned air, it is possible to provide an excellent effect of providing a wide range of air-conditioned spaces in a central location.
