The present invention relates to a ventilating suction device for comfortably ventilating the indoor space by sucking the indoor polluted air, for example, toilet odor, tobacco smoke, food cooking smell, sewer smell, etc., more specifically outdoors The present invention relates to a hybrid extraction device and a control method thereof capable of always exhibiting an optimum extraction performance by forcing the extraction device to be rotated by force or by wind power (natural wind) according to the rotational speed of the extraction device installed in the apparatus.

In multi-family dwellings, such as commonly used business buildings or apartments, the importance of ventilation efficiency and safety is always being emphasized regardless of the season.

The ventilation efficiency should be designed in consideration of the change in the area of the space to be ventilated, the temperature of the outside, the height and diameter of the ventilation duct, the wind speed and the air volume and the location of the rooftop. It must be designed to work.

In general, the suction device changes the pressure in the duct while the turbine blade is rotated by the wind, and draws out the indoor air through the duct (Natural Gravity ventilation) and the turbine blade by the power source. There is a forced drive type suction device (forced drive, mechanical ventilation) that is forced to rotate to change the pressure in the duct to suck the indoor air.

Both the non-powered air suction device and the forced drive type air suction device are installed at the end of the granular duct installed to pass through the bathroom and kitchen of the apartment and the residential complex, and the indoor air is sucked out through the duct. Its functions have different advantages and disadvantages.

That is, the non-powered draft device has the advantage of exhaling performance without a power source because it is rotated by the wind power, but if the wind is weak, not blown, the weather is hot, or the atmosphere is low pressure, the ventilation efficiency is sharply lowered, itself It acts as a resistance element that naturally reduces the flow of air through the duct has a disadvantage that the ventilation efficiency is lowered.

Therefore, in the case of non-powered draft device, the indoor air flow of each generation is hardly achieved if the wind is not blown, so the increase of carbon monoxide in the room and the contaminated air (tobacco smoke, kitchen food smell, toilet odor, sewage smell, etc.) ) Backflow or inflow into neighbors or other households through ducts may cause inconvenience to the residential environment, which may cause friction between neighbors.

On the other hand, in the forced drive type draft device, the turbine blade is rotated by the power source, and the indoor air is sucked out through the duct, so it is always possible to secure excellent ventilation efficiency regardless of environmental changes such as air volume, weather or climate. Although there is an advantage, it is inevitably required to be accompanied by power supply, and it is always operated (24 hours), so that the air is excessively drawn out of the room, resulting in a waste of energy due to low indoor temperature, and a generation adjacent to the aspirator. There is a disadvantage that the living environment is inconvenient due to the noise pollution caused by the operation of the aspiration device.

The present invention is to provide a hybrid hybrid suction device that combines the advantages of the non-powered suction device and the forced-driven suction device as described above, in particular, the blade is rotated by the wind in accordance with the rotational speed of the turbine blade of the suction device installed outside It is an object of the present invention to provide a hybrid suction device and a control method thereof capable of optimizing the suction performance by allowing the turbine blade to be rotated by a motor or by a motor.

The technical idea to solve the object of the present invention is to detect the speed at which the turbine blade rotates and the rotational speed is transmitted to the microcomputer and the microcomputer is compared to the set speed value if the rotation is slower than the set speed, the micom Power is supplied to the motor to forcibly rotate the turbine blades, and if the rotation speed is faster than the set speed range, the power is cut off from the motor so that the shaft of the turbine blades is rotated by the wind around the drive shaft of the motor. At the same time, it exhibits optimized wicking performance.

An embodiment of the hybrid suction device according to the present invention is installed in a duct (including a chimney) connecting the indoor and outdoor of the building to ventilate the indoor air for each household of a multi-family, such as multi-family, office buildings, apartments, a plurality of turbine blades And a base rotatably supporting a rotation shaft provided perpendicular to the center of the turbine blade.

Drive means for providing a rotational force to the rotating shaft;

Fixing means for fixing the driving means to the base;

Rotational speed sensing means for sensing a rotational speed of the turbine blade;

It can be achieved as a control means for selectively controlling the rotation or forced driving by the wind power by turning on / off the power of the driving means by the signal value detected by the rotation speed detecting means.

The control means according to the present invention is designed to be most suitable for the ventilation performance of the building, but the rotational speed of the turbine blade is an important factor affecting the aspiration performance, so if the blade rotational speed needs to be increased or decreased, the turbine blade must be forcibly rotated. The speed reference and the rotation speed range setting means that can be arbitrarily set by the user may be further included in the range of the speed reference to be operated by the natural wind.

The control method of the natural wind and forced drive hybrid exhaust device according to the present invention

An electric motor having a drive shaft connected to the rotation shaft and rotated therewith;

Fixing means for fixing the motor to the base;

Rotational speed sensing means for sensing a rotational speed of the turbine blade;

The microcomputer circuitly connected to the aspiration apparatus receives the speed value detected by the sensing means, compares it with the set speed value, and if the comparison value is within the set speed range, turns off the power supplied to the motor. To rotate the turbine blade and the motor shaft together by natural wind; and if the speed value detected by the sensing means is lower than the set speed, the turbine blade and the motor shaft are connected (ON) to supply power to the motor. It can be achieved through the step of forcibly rotating.

Hereinafter, with reference to the accompanying drawings for the hybrid suction device and the control method according to the present invention will be described in detail.

Referring to Figure 1, Figure 1 is a cross-sectional view illustrating an example of installing the suction device according to the present invention in a multi-unit house, the figurative duct (1) in the drawing is a chimney provided during the new construction of the building or the ceiling by the new construction or renovation of the building Or is installed in the wall.

Rotate freely with). That is, when power is supplied to the motor 21a, the rotational force is transmitted to the rotation shaft 13 by the power supply, and the turbine blade 11 is rotated. As the turbine blade rotates, a pressure change occurs in the duct, and contaminated air in the room is sucked out through the duct. If the power supply to the motor 21a is cut off, the turbine blade 11 rotates about the drive shaft 22 of the motor 21a in which the rotary shaft 13 is rotatably supported by the wind and performs a suction function. .

The fixing means 23 is for firmly fixing the motor 21a to the base 20.
