ていないのが実状である。 Various directionally variable air outlets have been proposed that utilize the principle of fluid elements, but most of these were developed primarily as air conditioner air outlets, and in order to apply them to duct-type air outlets, it is necessary to Since a control solenoid valve and other power sources are required, there are problems in construction and maintenance. Furthermore, the previously proposed variable direction air outlets are not designed to automatically change the wind speed, and the reality is that no air outlet that can arbitrarily change the direction and wind speed without power has been put into practical use. be.

る。 In a duct-based air conditioning system, when conditioned air is blown out from multiple outlets installed in the duct system, it would be possible to automatically control the blowing direction and speed according to the air conditioning load and type of conditioned air.
A comfortable space can be created while saving energy. The present invention provides a device that makes this possible. For example, during cooling, a jet stream with increased wind speed is blown out while changing the direction to enhance the draft feeling, and during heating, the wind speed is weakened to form a non-oscillating airflow. We have developed a system and an air blowing device for the system that allows arbitrary airflow control to generate warmth to be performed non-poweredly at each duct outlet.

絞られるかあるいは分流合流口５近傍のうず流が
強くなるようなものである。 The detailed configuration and operating principle of the device of the present invention will be explained below. The orifice 6 attached to the nozzle part 1 changes its orifice according to changes in the total pressure (static pressure) supplied from the duct to the nozzle part 1. Specifically, the orifice 6 shown in FIGS. It has a structure like this. That is, this orifice 6 is attached to the upper part of the diversion/merging port 5, but it has a hinge structure with a spring 10 interposed (the third
), for example, a structure supported by a plate spring 11 or a coil spring 12 made of phosphor bronze (Figs. 4 and 5), or a structure suspended by a spring 13 (Fig. 6).
), and when the total air pressure increases, the nozzle portion 1 is throttled or the eddy flow near the branch/merging port 5 becomes stronger.

に付着した噴流が発生し、主流の方向が変更す

向きは自己発信的に変わり、機械的な偏向翼より
も自然風に近いさわやかな風が得られる。 When the total air pressure is high and the orifice 6 is constricted, for example in the state shown by the solid line in FIG. As shown by the solid line in FIG. 2, the jet stream whose speed has been increased by being throttled by the guide 6 causes an airflow that strongly adheres to the wall surface of either the guide 2 or 2' as shown by the solid line in FIG. 2 (Coanda effect). Now guide 2,
If an airflow strongly adheres to side 2 of 2', a part of this jet is guided into the airflow passage 3 through the branch introduction port 4 provided at the tip of the guide 2, and becomes negative pressure. Due to the airflow from the airflow passage 3, the negative pressure in the vicinity of the branch flow confluence port 5 is reduced, and as a result, the strength of the eddy flow is weakened. When the strength of this eddy flow becomes weaker than the strength of the eddy flow at the other branch/merging port 5', a jet flow adhering to the wall surface of the guide 2' is generated, and the direction of the main flow is changed. Since this process is repeated one after another, the direction of the mainstream changes automatically, resulting in a refreshing breeze that is closer to natural wind than mechanical deflection blades.
次に送風全圧を低くして、オリフイス６のスプ
リング１０，１１，１２または１３の力の方が勝
つた状態、つまり、第２図の破線で示したように
オリフイス６が開きノズル口径が大きくなつた場

た場合）には、うず流によるコアンダ効果が弱ま
るので、第２図の破線で示したように中央部を直
進する気流が支配的になる。この直進気流の場合
は先の噴流よりも吹出速度はゆるくなる。 Next, the total air blowing pressure is lowered, and the force of the spring 10, 11, 12 or 13 of the orifice 6 is stronger, that is, the orifice 6 opens and the nozzle diameter becomes larger, as shown by the broken line in Figure 2. When the airflow becomes warm (or when it moves away from the diversion/merging port 5 as shown in Figure 6), the Coanda effect due to the eddy flow weakens, so the airflow that goes straight through the center becomes dominant, as shown by the broken line in Figure 2. become a target. In the case of this straight air stream, the blowing speed is slower than that of the previous jet stream.

成できる。 In this way, the direction change and speed of the blown air flow are controlled by changing the total air blowing pressure of the duct system, but this adjustment of the air blowing total pressure can be easily performed by damper control. . Therefore, for example, in the cooling season, the total air pressure is increased to blow out cold air that gives a draft feeling due to the Coanda effect, and in the heating season, the damper is designed to blow out a slow straight flow without the draft feeling. All you have to do is adjust it. In addition to this method of use, if the duct is provided with a means for varying the total pressure of the blown air to periodically vary the total pressure of the blown air, the device can be configured to arbitrarily vary the blowing direction and speed. can.

At points a to d of the cycle, airflows as shown in a to d of FIG. 11 are obtained, and airflows whose blowing directions and blowing speeds slightly change are obtained.

The internal space of the blade 8 can be configured as a controlled flow chamber by allowing the airflow to pass through the blade. The control blades 8 are made manually movable in the vertical direction so that the air volume can be adjusted as appropriate. This makes it possible to adjust the blowing device of the present invention, which is attached to various locations in the duct, depending on its installation location.
