Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a tornado generating device that aims to purify the air in a specific space with high efficiency.

[Conventional technology]

JP-A-62-261842 and JP-A-62 are methods for purifying locally generated contaminated air without dispersing it.
There existed a tornado generating device as shown in FIG. 3 disclosed in Japanese Patent No. 280529.

This is a pillar-shaped air outlet duct 13 arranged at four locations around the area.
From the air outlet 12 of
It blows air toward the area No. 5 to generate a tornado. Arrow 15 indicates the flow of blown air.

[Problem to be solved by the invention]

However, in the above-described conventional technology, the air is uniformly blown in a predetermined direction from the outlet 17 of the outlet duct 13, so that disturbances such as the airflow of the air conditioner for heating and cooling or drafts may cause the vortices to flow. If the center is off,
There was a problem that contaminated air could not be properly exhausted.

An object of the present invention is to provide a tornado generator that can effectively exhaust contaminated air by controlling the center position of the vortex.

[Means to solve problems]

The first aspect of the present invention is that a rotatable air duct having a plurality of air outlets arranged vertically is disposed around the air duct, a mechanism for rotating the air duct is provided, and a mechanism for rotating the air duct is provided in the upper center. A tornado generating device is characterized in that it is provided with a suction port having a suction fan, and has a control device that controls the wind direction and air volume of the air outlet. This tornado generating device is characterized by controlling the wind direction and flow at the outlet using signals from a sensor.The third feature is that a vortex center position specifying device is provided and the wind direction and air volume at the outlet are controlled by the position signal. This is a tornado generating device featuring:

[Function] In the present invention, the hot water area where contaminated air is generated is sensed,
Air is purified efficiently because the direction and size of air blowing are changed so that the center of the vortex is located at the hot spot where contaminated air is generated.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings.

A rotatable blow-off duct 1 having a plurality of blow-off ports 2 in the vertical direction is erected at four locations equally distributed around the periphery. A duct 3 is installed in the ceiling so as to connect with this air duct 1.
is located.

The duct 3 has a general mechanism 9 for rotating the rotatable blowing duct 1.

Further, the duct 3 is divided into several completely separated suction ducts 10 as shown in FIG. 2, and a damper 12 is connected to each suction duct 1-10, followed by a suction fan 8. A suction port 4 is arranged.

By opening and closing the damper 12, contaminated air can be sucked from the suction duct 10 above the generation location.

Further, a blowing fan 5 is connected to the duct 3 for conveying air to the blowing duct 1.

A sensor 18 for sensing the position of contaminated air is installed under the duct 3 or inside the blowout duct 1. The sensor 18 is a smoke detection sensor,
Human body detection sensors are used.

The signal sensed by the sensor 18 is input to the control device 6, which controls the direction of the blowout duct 1, the ability of the fan 5 to convey air, and the opening and closing of the suction duct 10.

This allows a tornado to form at the location where the pollutants are generated.

Furthermore, by opening and closing the damper 12, the suction duct IO above the location where pollutants are generated is opened.

At this time, a vortex center position specifying device that can freely set the center position of the vortex is provided, and the position signal determines the direction of the blowout duct 1, the capacity of the blowout fan 5 for conveying air, and the suction duct 10. The air volume may be adjusted by controlling the opening and closing of.

Arrows 15 indicate air flow.

Air is then blown out from the air outlet 2 in the tangential direction of the virtual cylinder centered on the pollutant, forming a tornado.

In this case, the blowing direction of the air from the blowing outlet 2 is directed upward as required.

This tornado is sucked in through the suction port 4 and discharged to the outside. Air purification is performed in this way.

[Effects of the Invention] Since the present invention is configured as described above, efficiency can be improved by aligning the center of the vortex with the position of the pollutant by adjusting the direction of the blowout port and the size of the blowout airflow. Good air purification is achieved.
