Vortex type ventilator

The present invention relates to a vortex type fan. More specifically, by generating the vortex by the rotation of the fan consisting of the rotating plate, the blade and the connecting rod to induce the pressure difference and the air flow direction to allow the air, such as external pollutant source into the housing quickly and efficiently, the introduced pollutant source The air of the back is maximized the exhaust efficiency by moving quickly and easily in the direction of the exhaust pipe by the vortex generated by the exhaust auxiliary part that rotates with the fan, forming the exhaust auxiliary part in the form of higher order graph and having a plurality of radial swirl By providing a step to facilitate the generation of vortex, as well as to form the inclined curved surface so as to move away from the center of rotation to easily move the air, such as pollutant source, by the support member having the same direction as the discharge aid Rapidly direct air such as pollutants to the exhaust pipe through a number of through holes It relates to a vortex-type fan that can be discharged.

Exhaust systems, or fans, are generally used in factories, homes, restaurants, etc., where a lot of pollutants are generated. The ventilator is useful when a partial source of contamination occurs on the floor away from the exhaust pipe, when it is difficult to install the exhaust pipe near the source of pollution by other installations, or when a source of pollution occurs momentarily. In addition to the source of pollution, the exhaust fan discharges odors and moisture generated in home bathrooms to the outside.

Such fans have various problems in terms of performance. As the ventilator moves away from the exhaust pipe, the efficiency of removing contaminants decreases drastically. For example, if the odor and moisture in the toilet stays near the floor, it is difficult to discharge because the distance to the ceiling fan installed. In addition, a fan installed in a closed room has a problem that a tremendous noise is generated by the driving of the motor and the rotation of the fan.

For this reason, the fan is preferably installed as close as possible to the location of the generation of pollutants. However, there is a limitation in the installation conditions because it interferes with the movement of the work process and the workers and the distance between the floor and the ceiling.

In order to solve this problem, a fan for expanding an exhaust area using vortices has been developed. The vortex type fan installs a vortex generating fan at the inlet side of the exhaust pipe and rotates the fan. The fan generates a vortex like a donut shape around the exhaust pipe to efficiently suck contaminated air into the exhaust pipe.

However, in the case of such a vortex-type fan, the vortex should also be relatively large in proportion to the distance from the inlet of the exhaust pipe to the pollutant, so that contaminated air can be easily sucked into the exhaust pipe. Attempts have been made to maximize the rotational force of the fan in order to increase the size of the vortex, but there is a limit and there is a problem in that the power usage is increased. For this reason, even if the size of the vortex is increased by maximizing the rotational force of the fan, in the existing vortex type fan structure, the source of the inhalation caused by the vortex generated by the fan is vortices and pollutants due to various structures including the motor provided between the fan and the exhaust pipe. It is reflected by this structure, and redistribution occurs in the direction of the pollutant, and noise increases due to the occurrence of turbulence caused by mutual interference between the inflowing flow and the inflowing flow in a narrow area below the exhaust pipe. There is a problem that there is a fear of causing an additional spread of the existing pollution.

Therefore, there is a need for the development of a technology capable of quickly discharging the pollutant sucked by the vortex without causing diffuse reflection or the like and rapidly discharging it toward the exhaust pipe, suppressing the generation of noise, and preventing further diffusion of the pollution.

The present invention has been devised to solve the above problems, and in particular, by inducing a pressure difference and an air flow direction, air such as external pollutants can be introduced into the housing quickly and efficiently, and air such as introduced pollutants is assisted. It is an object of the present invention to provide a vortex-type fan that can maximize the exhaust efficiency by quickly and easily moving toward the exhaust pipe by the vortex generated by the device.

Vortex type ventilator according to the present invention devised to achieve the above object is a housing having an inner diameter larger than the other end in a hollow cylindrical shape inside; A grill coupled to one end of the housing; A motor provided inside the housing; A rotating shaft mounted to the motor; A fan including a rotating plate mounted to the rotating shaft and a plurality of blades disposed along the outer edge of the rotating plate and fixed in a radial direction; And an exhaust auxiliary part provided between the motor and the fan and mounted to the rotating shaft.

In addition, the discharge assistance portion may have a curved surface convex in the fan direction and concave in the motor direction.

In addition, a plurality of steps may be provided on the curved surface in the fan direction among the exhaust auxiliary parts, and a boundary of the steps may form a radial curve extending toward a rotation axis as a whole.

According to the present invention, by generating a vortex by the rotation of a fan consisting of a rotating plate, a blade and a connecting rod to induce a pressure difference and air flow direction, air such as an external pollutant source can be introduced into the housing quickly and efficiently, and the introduced pollutant source The air of the back is maximized the exhaust efficiency by moving quickly and easily in the direction of the exhaust pipe by the vortex generated by the exhaust auxiliary rotating with the fan.

In addition, according to the present invention, by forming the discharge auxiliary portion in the form of a high order function graph and having a plurality of steps having a radial vortex shape to facilitate the generation of vortex, as well as to form a sloped surface so as to move away from the rotation center It is easy to move air such as a pollutant, and there is an effect that the air such as the pollutant can be quickly discharged to the exhaust pipe by a support member having the same inclination as the discharge aid.

FIG. 7 is a perspective view of the discharge assisting part of FIG. 1, and FIG. 8 is a plan view of FIG. 7.

1 to 7, the vortex-type fan according to a preferred embodiment of the present invention, the housing 10, the grill 20, the fan 30, the discharge auxiliary portion 40, the rotating shaft 50, the motor ( 60, the motor case 70, the motor cover 75, and the exhaust pipe 80.

The housing 10 is formed in a cylindrical shape with an empty inside. The grill 20 is coupled to one end of the housing 10, and the exhaust pipe 80 is coupled to the other end. The housing 10 accommodates the fan 30, the discharge assistance unit 40, the rotation shaft 50, the motor 60, the motor case 70, and the motor cover 75 therein.

One end of the housing 10 has an extension 12 having an inner diameter larger than the other side. Expansion portion 12 is formed to increase the inner diameter gradually toward the end, so that it is possible to efficiently absorb external pollutants and the like. In addition, the expansion unit 12 is coupled to the installation member 5, to facilitate the installation of the vortex-type fan.

The support member 14 is provided inside the housing 10. The support member 14 fixes and supports the motor case 70 and the motor cover 75 inside the housing 10, and a plurality of through holes are formed to contaminate the source sucked by the fan 30 and the discharge assistance part 40. The back is easily discharged to the exhaust pipe (80).

The support member 14 is formed to be inclined to be lowered toward the inner peripheral surface of the housing 10 in the motor case 70 direction. That is, when referring to the exhaust pipe 80, the support member 14 in the exhaust pipe 80 than the length from the exhaust pipe 80 to one end of the support member 14 (part coupled with the motor case 70). It is preferable that the length to the other end of the portion (part coupled with the inner peripheral surface of the housing 10) is shorter. This allows the support member 14 to more firmly support the motor case 70 and the motor cover 75, and at the same time, the source of contamination introduced through the fan 30 passes through the discharge assistance unit 40, and the discharge assistance unit ( To reach the support member 14 having an inclined direction similar to 40, and to be quickly and effectively discharged through the through hole provided in the support member (14).

The grill 20 is coupled to one end of the housing 10. The grill 20 is formed in a radial vortex shape around the center hole, and the rotation direction of the vortex is preferably formed to be the same as the rotation direction of the step 42 formed on the surface of the discharge assistance part 40.

The fan 30 is positioned between the grill 20 and the discharge auxiliary portion 40, and rotates about the rotation shaft 50 to generate vortices. Referring to FIG. 5, the fan 30 includes a rotating plate 32 mounted on the rotating shaft 50 to rotate, a plurality of blades 34 arranged along the outer edge of the rotating plate 32 and fixed in a radial direction, And a connecting rod 36 for connecting and supporting the rotating plate 32 and the rotation center.

The wing 34 is preferably fixed to the upper surface of the rotating plate 32 perpendicular to the disk surface. Although not shown, a portion of the wing 34 may be formed extending radially outward of the rim of the rotating plate 32.

When the blade 34 is set on the rotating plate 32 and fixed, the inclined portion is provided at a portion of the blade 34 positioned at the center of rotation so that the height thereof gradually decreases toward the center of rotation of the rotating plate 32. It is preferable. This decreases the frictional resistance with air as the fan 30 rotates toward the center of rotation of the rotating plate 32, and the farther from the center of rotation of the rotating plate 30, the air inside the rotary plate 30 is outward. In order to effectively push out (see Fig. 6), and to effectively absorb the pollutant and the like through the space between the connecting rod (36).

Referring to FIG. 6, when the fan 30 rotates, the blade 34 pushes air inside the rotating plate 32 to the radially outer side of the rotating plate 32. When the contaminated air is sucked into the exhaust pipe 80, the contaminated air to be sucked into the exhaust pipe 80 and the inside of the rotating plate 32 are attempted to enter the exhaust pipe 80. Due to such a flow of air, vortices are formed in the lower part of the rotating plate 32, respectively. Due to such vortices, a pressure difference is generated and an air flow direction is formed, whereby air including an external pollutant and the like is sucked into the exhaust pipe 80 well.

Discharge assistance unit 40 is provided between the fan 30 and the motor 60, mounted on the rotary shaft 50 and rotates in the same direction with the fan 30. The discharge assisting part 40 has a curved surface that is convex in the fan 30 direction and concave in the motor 60 direction. In other words, the discharge aid 40 is made inclined toward the farther away from the rotation (see Fig. 2), such a slope is in the form of a high-order function graph. Therefore, the lower the distance from the rotation center than the portion closer to the rotation center becomes greater. For example, when the point where the center of rotation of the discharge auxiliary portion 40 and the rotation axis 50 meet is the origin (0, 0), the surface of the discharge auxiliary portion 40 in Figure 2 is y = -ax ² (a is positive Constant). This is to effectively discharge toward the exhaust pipe 80 through the steep inclined surface as the air, such as a pollution source introduced through the rotation of the fan 30 away from the center of rotation.

7 and 8, a plurality of steps 42 are provided on the curved surface of the exhaust auxiliary part 40 in the direction of the fan 30, and the boundary of the steps 42 is curved to form a center around the rotation axis 44 as a whole. It forms a radial curve extending out to.

Exhaust assistance portion 40 forms a vortex by rotation similar to the fan 30. The vortex pushes air in a direction away from the rotation center of the discharge auxiliary part 40 similarly to FIG. 6, and quickly exhausts air such as a pollutant introduced through the fan 30 by the pressure difference and the air flow direction. Inhale in the direction of (80).

In order to help in forming the vortex, a plurality of vortex-shaped steps 42 are formed on the curved surface of the exhaust auxiliary part 40 in the direction of the fan 30. Referring to FIGS. 7 and 8, the step 42 slightly increases in the clockwise direction. This step 42 forms a height difference between adjacent curved surfaces to facilitate vortex formation. In FIG. 7 and FIG. 8, the rotational direction of the discharge assistance part 40 becomes counterclockwise. The vortex radial shape generated by the step provided in the discharge assistance part 40 is similar to the radial shape of the grill 20.

The motor 60 is provided inside the housing 10 and is equipped with the rotation shaft 50. As described above, the motor 50 is fixedly received by the motor case 70 and the motor cover 75, and the motor case 70 and the motor cover 75 are supported by the support member 14. same.

The exhaust pipe 80 is coupled to the other end of the housing 10.

Referring to Figure 2, it will be described the operation of the vortex-type fan according to a preferred embodiment of the present invention.

When the fan 30 is rotated by the driving of the motor 60, vortices are generated by the vanes 34 of the fan 30, and the external air pollution source and the like are formed by the air pressure direction and the air flow direction formed by the vortex formation. Air included is introduced into the housing 10.

Air, such as a pollution source introduced into the housing 10 is provided with a large pressure and flow direction to move toward the exhaust pipe 80 by the vortices generated by the rotation of the discharge auxiliary portion (40). At this time, since the discharge auxiliary portion 40 has an inclined curved surface that decreases as it moves away from the rotation center, air such as a pollutant introduced into the surface of the discharge auxiliary portion 40 quickly moves toward the exhaust pipe 80. Since the support member 14 provided in the housing 10 has an inclination in the same direction as the discharge assisting part 40, air such as a pollution source that reaches the support member 14 is passed through the through hole of the support member 14. It is quickly discharged to the exhaust pipe (80).
