Description

Blower {FAN}

The present invention relates to a blower that allows a wide range of air intake and blowing the air to be sucked in direct sunlight.

In more detail,

It has an inlet housing for introducing (inflowing) outside air into the inlet and outlet side of the impeller housing in which the blowing impeller is mounted therein, and an outgoing housing for directly blowing the forcedly blown air in a predetermined direction or position. The housing has a wider inlet and the outgoing housing has a smaller outlet so that the outside air can be sucked in a wide range and the air blown to the target point can be directly discharged.

In particular, the present invention is mainly installed in a room such as an indoor parking lot so that the polluted air in the room can be forced out by a predetermined exhaust fan (device). It relates to such a blower for being able to force forced direct discharge to the exhaust fan side.

In recent years, as the number of automobiles increases rapidly, it is becoming common to provide parking lots indoors as well as to park outdoors. Especially, indoor parking lots are mainly provided in the basement floor.

Although indoor parking lot such as underground parking lot is widely used, there is a problem that the air of indoor parking lot is polluted by exhaust gas generated from automobiles.In order to solve the air pollution of indoor parking lot, The same institutional provision is in place to reduce the pollution level of indoor parking lots.

As a ventilation device (system) for ventilating an indoor parking lot, a general duct system, a turbo vent (divent) method, and a turbo system (muduct system) are known.

In the ventilation system, the general duct is provided with a supply duct for supplying air and a discharge duct for inhaling and releasing polluted air in the room, respectively. A discharge port for discharging air into the room and a suction port for introducing (suctioning) the contaminated indoor air into the discharge duct were provided at predetermined positions.

In this way, the duct circulation method using the supply duct and the discharge duct releases fresh air from the ceiling side to the floor through the outlet of the supply duct and inhales when it is raised to the polluted air ceiling circulating the room. The method of discharging the air of the air is slowed down because the air is sucked in and discharged in a state where the contaminated air is diffused into the room.

Due to the slow air circulation (convection), not only do the air congestion increase the indoor pollution, but the CO congestion causes the room to corrode or cause condensation on the side walls.

In particular, since most of the ducts are rectangular, the construction and repair and maintenance are not easy, and the height of the duct is high, resulting in high floor height. In order to increase the operating power of the fan (FAN), if you increase the operating power of the fan, there was a problem that the noise is greatly generated.

In the ventilation system, the turbo vent system uses a duct, a fan, and a nozzle, and sucks the air in the room by a fan, forcibly blows the air, and supplies the air through the duct. It is to be discharged by injecting through the guide to the exhaust side.

Korean public disclosure No. 98-57234 is known as using a turbo vent (di-revent) method.

This is done by installing a duct in a turbo vent (di-vent), which has a fan inside the casing where sound absorbing agent is adhered to the inner wall of the room where the air intake fan and the exhaust fan are mounted, and mounting nozzles in the duct at predetermined intervals. When operating the fan built in the turbo vent, the air in the room is sucked through the casing to be forcedly blown, transferred through the duct, and then forced to the exhaust fan through the nozzle mounted on the duct. .

However, the turbo vent (di-vent) method also has to install a duct to transfer forced air and to install a separate nozzle in the duct, such as cumbersome on the equipment, which is a problem that requires a lot of equipment cost There was. However, it was possible to reduce the floor height by using a smaller diameter duct than the duct adopted in the general duct method.

If you want to change the line that is already installed, it can be done more easily than general duct, but you need to remove the nozzle from the duct and move the duct to install it. There was a hassle and discomfort such as being unable to use again.

In addition, the turbo system (mudless type) is designed to force the air blown to the exhaust fan side by installing a fan with an integrated nozzle in the ceiling of the room where the intake fan and the exhaust fan are installed.

This turbo (ductless) method can quickly dilute the pollutants in the exhaust gas, thus eliminating the phenomenon of CO gas congestion, and can reduce the height of the floor without the use of ducts and facilitate the construction. It does not need to change the line, it is easy to maintain, it is easy to ventilate, and it has the characteristics that it can reduce the noise.The turbo system (Muduct system) is ventilated according to the characteristics of the fan to be installed. Efficiency will vary.

As a nozzle nozzle which can be mounted and used in a turbo system (deductible system) in this way, the indoor publication utility model publication No. 98-65627 is known.

It is equipped with an air inlet provided with an air inlet protection net on one side, and a nozzle in which a motor is integrated inside the rectangular-shaped housing in which the nozzle housing distribution groove is formed on the opposite side, but the tip is exposed through the nozzle housing distribution groove. When the fan is operated by the motor, the air in the room is sucked into the housing through the air inlet by the suction force of the fan, and the sucked air is forcedly blown by the fan and then injected through the nozzle housing. Lose.

However, the nozzle 구성 configured and operated in this way is pointed out the following problems. The external air is sucked in (inflow) by the fan and forced air is blown by the fan, so if the rotational force of the fan is weak, the suction power is weakened and the sucked air Once stagnant inside, it is blown again, which wastes power. In addition, the air introduced into the housing collides with each other in the inside of the housing and collides with the incoming air, causing the air blowing capacity to be lowered, thereby causing the air to be randomly introduced to generate noise. There was a problem.

In particular, since the outer appearance of the housing was in a rectangular parallelepiped shape, the outer appearance could not be made beautiful.

The present invention is to provide a blower (FAN) that can be used in a turbo system to solve the above problems and closed ends.

The present invention provides an inlet housing for introducing indoor air into the housing, an impeller housing for mounting an impeller and a motor to blow air from the inlet housing, and a discharge housing for discharging the blown air in a predetermined direction. It is an object of the present invention to provide a blower (FAN) that can be decomposed to each other on the same vertical line, so that forced air blowing and exhausting the sucked air can be performed simultaneously on the same vertical line.

Another object of the present invention is to allow the air to be blown and forced to be discharged after exhausting the fan and the fan housing as a unitary consolidation to improve the blowing capacity by the same vertical line, but to increase the air intake The present invention provides a blower having excellent delivery capability by allowing a lot of indoor air to be introduced and increasing the output power by making the outlet smaller.

Still another object of the present invention is to provide a blower that improves the air discharging capacity, thereby preventing CO from stagnation in the room, thereby reducing indoor pollution and preventing corrosion of buildings.

Another object of the present invention is to prevent the noise generated when the air is introduced into the impeller so that the incoming air is introduced into the impeller without colliding with each other to relax the resistance and induce the air to the impeller It prevents noise or vibration from occurring by preventing collisions.

It is to provide a blower that can improve the delivery capacity by being guided to the delivery induction pipe narrowed in a streamline as the air to be sent is rotated.

Another object of the present invention is to provide an air blower that can be easily cleaned by allowing the inlet housing and the impeller housing and the discharging housing to be disassembled and thus prevent the contamination of the inside.
