The vortex control unit 140 has an outer diameter of the suction area due to the vortex generated by the swirler fan 130 is collected from the inlet end of the exhaust pipe 110 to the center of the suction port 112, the overall length of the suction area. Is provided in the exhaust pipe 110 to control the length.

As shown in FIGS. 2 and 3, the vortex control unit 140 extends inclined at an angle in the suction direction from an end of the exhaust pipe 110 or an end of the horizontal plane 149 provided therein to be inclined at an angle. The inclined wall 141 may be provided in a circumferential cross-section along the outer rim of the exhaust pipe 110 in a circumferential direction and may be provided in a conical section extending inwardly downward.

In addition, the vortex control unit 140a is inclined at a predetermined angle in the suction direction from the end of the horizontal plane 149a provided at the end of the exhaust pipe 110, as shown in FIGS. 4A and 5B.

Here, the horizontal plane 149 connected to the inclined wall 141 on the conical section may be provided in a substantially disk shape, and connected to the left or right pair of inclined walls 142 and one or left or right pair of vertical walls 143. The horizontal surface 149a may be provided in a substantially rectangular plate shape, and the inclined wall and the vertical wall may be provided in a polygonal shape such as a triangle or a square while being connected to each other.

And, as shown in Figure 6, the vortex control unit 140b includes an arc-shaped inclined wall 144 extending a predetermined length downward to have a convexly curved cross section from the end of the exhaust pipe 110 to the top.

Each end of the inclined wall 142 and the vertical wall 143 provided in the vortex control unit (140a, 140b) is shown and described as being provided in a straight line, but is not limited thereto, and may be provided in a substantially arc shape.

In addition, in the vicinity of the swirler fan 130, it is preferable to include a suction filter 150 to remove the foreign matter contained in the external suction air forcibly sucked, this suction filter 150 is inclined the vortex control unit The wall 141 or the vertical wall 143, the arc-shaped inclined wall 144 and the support bar not shown may be connected to be supported horizontally.

Accordingly, when the local exhaust device 100 having such

vortex control units

140, 140a and 140b is applied to the kitchen hood, the exhaust pipe is formed by the

inclined walls

141 and 142 or the vertical wall 143 and the arc-shaped inclined wall 144. The outside air region (outside the horizontal plane, corresponding to the external surface of the inclined wall or the vertical wall) on the outside of the 110 and does not need forced inhalation; In addition, since the external air areas (areas corresponding to the horizontal surface, the inclined wall or the vertical surface of the vertical wall on the drawing) that require forced suction are separated from each other, the lower portion of the rotating plate 132 is directly below the rotation of the swirler fan 130. It is possible to fundamentally prevent inhalation by mixing unnecessary external air with the generated vortex.

In addition, the

inclined walls

141 and 142, the vertical walls 143, and the arc-shaped inclined walls 144 may be limited to extend the suction area formed by the vortex near the inlet end of the exhaust pipe 110 to the outside. Therefore, the suction area can reduce the outer diameter so as to gather from the inlet end of the exhaust pipe 110 to the center side of the exhaust pipe 110 and induce the entire length of the suction zone to be long toward the source of contamination.

Due to this, the suction air suctioned toward the suction port 112 is gradually narrowed toward the suction port side by the

vortex control units

140, 140a and 140b formed of the

inclined walls

141 and 142 or the vertical wall 143 and the arc-shaped inclined wall 144. It is exhausted through the suction port 112 and the exhaust pipe 110 rapidly and quickly through the suction region is formed to be concentrated.

In addition, the swirler fan 130 and the corresponding suction port 112 penetrates through the

horizontal surfaces

149, 149a and 149b of the vortex control unit formed through the closed lower surface of the exhaust pipe 110 or assembled to the open end of the exhaust pipe. It may be formed, the suction port 112 may be provided with the vortex control unit may be moved to or from the shank or independently moved while varying the interval corresponding to the swirler fan 130 with respect to the exhaust pipe as a fixing member.

On the other hand, any one of the left and right pair of vertical walls 143 facing each other in the vortex control unit (140a, 140b) is disposed so as to correspond to the wall surface, is formed at the inlet end of the exhaust pipe by the vertical wall disposed to correspond to the wall surface Since it is possible to restrict the suction area from being extended to the outer wall surface, it is possible to prevent the suction and exhaustion efficiency from being lowered while the vortex of the suction area hits the wall surface.

When operating the local exhaust device 100 having the configuration as described above to inhale pollutants, such as smoke, soot generated from the pollution source with the air and to exhaust the sucked external air to the outside, the motor member 120 When the external power is applied to the swirler fan 130 disposed below the inlet 112 of the exhaust pipe 110 is rotated in one direction around the drive shaft (122).

At the same time, the suction fan 125 provided in the drive shaft 122 and disposed in the exhaust pipe 110 is also rotated at the same time to generate a suction force of a certain intensity in the exhaust pipe 110.

The intake and exhaust force generated in the exhaust pipe 110 may be further increased by an external intake and exhaust force transmitted through an exhaust duct connected to the exhaust pipe.

In this case, a donut-shaped vortex while pushing the air immediately below and near the rotating plate 132 in the radial direction of the swirler fan 130 by the swirler fan 130 rotated together with the suction fan 125. Vortex is forcibly formed by the swirler fan 130 in the area corresponding to the source of pollution, such as a cooking appliance is the air curtain that partitions the area where the pollutant is generated and the area where the pollutant does not occur. To do.

At the same time, the air containing contaminants generated at the source of pollution at the center of the vortex is forced through the inlet 112 of the exhaust pipe 110 by the intake and exhaust force forcibly formed in the exhaust pipe by the suction fan 125. By forming an intake air fluid flow proceeding from the bottom to the upper portion in order to inhale, the pollutants and air generated from the pollution source are exhausted to the outside through the exhaust pipe 110 and the exhaust duct 115.

And, by providing the

vortex control unit

140, 140a, 140b consisting of the

inclined wall

141, 142 or the vertical wall 143, arc-shaped inclined wall 144 in the lower portion of the exhaust pipe 110, forced suction is unnecessary by the vortex control unit In addition to the external air region and contaminants, it is possible to securely separate the external air region requiring forced suction to prevent unnecessary external air from being sucked into the exhaust pipe and exhausted.

In addition, by limiting the expansion of the suction region due to the vortex generated by the swirler fan 130 to the outside by the vortex control unit 140 to collect the center of the suction region toward the center side of the exhaust pipe (110). Since the entire length of the suction region can be extended to the source of pollution, the intake and exhaust efficiency of forced suction and exhaust through the suction port 112 can be increased.

Accordingly, at the inlet end of the exhaust pipe 110, an external air together with the contaminants generated from the source of pollution by a structural change including a vortex control unit for controlling the vortex so as to concentrate and reliably separate the upper region of the vortex generating region from other regions. It is possible to further increase the suction efficiency of intensively forced suction and exhaust efficiency discharged to the outside through the exhaust pipe.

7 is a block diagram showing an island-type kitchen system having a local exhaust device according to a preferred embodiment of the present invention.

The exhaust pipe 110a is illustrated and described as being fixedly installed on the upper surface of the independent structure 200, but is not limited thereto. In general, the exhaust pipe 110a is lowered so that the entire body or a part of the exhaust pipe 110 is embedded in the internal structure of the independent structure 200. And it may be made of a tubular member which is raised by the lifting means not shown so as to project a certain height to the upper portion during cooking so as to remove the contaminants generated during cooking using the cooking appliance.

The exhaust line 114 is connected to an exhaust duct 115 that provides an exhaust force for discharging the suction air forced inhaled from the suction port 112a to the outside and is forcibly sucked with contaminants through the suction port 112a. Air is exhausted to the outside through the exhaust duct 115.

Here, the exhaust line 114 is preferably provided with a filter unit 117a having a filter member to filter the contaminants contained in the suction air forcedly sucked in the middle of the length.

Accordingly, the suction air forced into the exhaust line 114 is filtered by the filter unit 117a provided in the middle of the exhaust line 114 and then exhausted to the outside.

As shown in FIGS. 8 and 9, the motor member 120 is a power source for generating a rotational driving force when power is applied, and the inside of the exhaust pipe 110a may be forced to rotate the swirler fan 130 in one direction. It may be fixedly installed in the space via the motor support member 124.

Here, the motor member 120 is illustrated and described as being mounted in the inner space of the exhaust pipe 110a, but is not limited thereto. The motor member 120 may be mounted to be exposed to the outside of the exhaust pipe 110a.

The drive shaft 122 of the motor member 120 may be provided with a suction fan (not shown) to generate the intake and exhaust force inside the exhaust pipe (110a) disposed perpendicular to the upper surface of the independent structure 200, An end of the drive shaft 122 is provided with a swirler fan 130 which is rotated together with the suction fan.

The swirler fan 130 is a rotating plate 132 mounted to the end of the drive shaft 122 extending from the motor member 120, and a plurality of vortex generating wings are provided on the outer surface at regular intervals in the circumferential direction ( 134).

Accordingly, the external air containing various types of contaminants generated from the pollution source such as a cooking appliance provided on the upper surface of the independent structure 200 during the rotation drive by the drive motor 120 from the top of the pollution source. The vortex is generated between the pollution source and the suction port 112a so as to form a suction area that suctions upwardly toward the suction port side.

The

vortex generator

140, 140a, 140b is provided with an inclined wall 141 provided in a cross section extending in a suction direction at an angle inclined from a vertical outer surface of the exhaust pipe 110a in which the suction port 112a is formed.

vortex control units

140, 140a and 140b is applied to the island kitchen system, external air that is present outside the exhaust pipe 110a by the vortex control unit does not need forced suction. Since the area and the external air area that is present in the pollution source corresponding to the suction port 112a and which require forced suction are separated from each other certainly, they are generated in the vicinity of the rotating plate 132 during the rotation of the swirler fan 130. It is possible to fundamentally prevent inhalation of unnecessary external air mixed with the vortex.

In addition, the suction area is limited at the inlet end of the exhaust pipe 110a because the vortex control unit restricts the suction area formed by the vortex generated above the vertical outer surface of the exhaust pipe 110a from extending outward. At the same time as the center of the suction port 112a can be collected and the overall length of the suction area can be formed longer. Therefore, the suction air sucked into the suction port 112a is exhausted through the suction port 112a and the exhaust pipe 110a rapidly and quickly through the suction area gradually narrowed by the vortex control unit.

On the other hand, as shown in Figure 8, the inlet 112a may be provided on the outer surface of the vertical upper body of the exhaust pipe 110a, but is not limited to this, as shown in Figure 9, the pollution source It may be provided on the outer surface of the upper body of the exhaust pipe 110a inclined at an angle.
