The discharge outlet of the terminal is made in direct communication with the outside of the building. That is, the discharge port of the end of the exhaust duct 2 is connected to the embedded sleeve 5 of the wall via the connecting member 6 and directly connected to the outside.

As described above, due to the structural characteristics of the direct exhaust ventilation system in which the exhaust duct 2 is open to the outside, the conventional direct exhaust ventilation system is installed in each room because backwind and outside air can be easily introduced into the building through the exhaust duct. It is common to provide the electric damper 7 together with each side of the discharge port of the fan.

However, although the electric damper 7 can prevent the reverse wind from flowing into the room, the exhaust duct 2 is still open to the outside through the buried sleeve 5 so that the outside air is passed through the terminal outlet. It was easily introduced, which caused heating loss due to heat loss in winter and cooling loss due to heat inflow in summer. In addition, the exhaust duct (2) is present in the open state outside the bar easily condensation occurs inside the mold or bacteria, there was a problem that the fine dust and noise inflow as it is.

In the following, preferred embodiments, advantages and features of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a plan view of the interior of the building installed a ventilation system using a magnet damper according to the present invention.

Referring to FIG. 2, the ventilation system according to the present invention includes a fan 10 installed in each room including a bathroom in a building, an exhaust duct 20 connected to each fan 10, and A magnet damper 100 is installed on the wall 40 and connected to the discharge port 23 of the terminal of the exhaust duct 20.

The ventilator 10 is a component for forcibly suctioning the air in the room through a ventilation fan mounted therein, and is installed in the ceiling and connected to the exhaust duct 20.

The exhaust duct 20 is buried in the ceiling as a component corresponding to a flow path for discharging the internal air forcedly sucked by the ventilator 10 in each room to the outside of the building, and preferably a flexible hose or a clean hose is used. Can be. The exhaust duct 20 is provided with a main duct 22 and a branch duct 21, the fan 10 of each room is directly connected to the main duct 22 or via the branch duct 21 through the main duct ( 22).

On the other hand, in the case of the direct exhaust ventilation system, the internal air sucked by the fan 10 is configured to be discharged directly to the outside through the exhaust duct 20, and thus the exhaust duct 20 embedded in the ceiling is the main duct 22. Termination end outlet 23 of the through) is configured to be in direct communication with the outside of the building through the wall (40). That is, the terminal discharge port 23 of the main duct 22 is connected to the buried sleeve 45 provided to penetrate the building wall 40 and directly connected to the outside of the building.

The magnet damper 100 of the present invention is interposed between the buried sleeve 45 of the wall 40 and the discharge outlet 23 of the terminal end of the main duct 22, and backwinds into the exhaust duct 20 opened to the outside. Corresponds to the component to prevent the outside air flow or condensation occurs.

3 is a longitudinal exploded cross-sectional view of a magnet damper applied to the direct ventilator ventilation system according to the present invention, FIG. 4 is a front side perspective view of the magnet damper applied to the direct ventilator ventilation system according to the present invention, and FIG. Rear side perspective view.

2 to 5, the magnet damper 100 applied to the direct exhaust ventilating system of the present invention is installed in a wall 40 through which the discharge outlet 23 of the exhaust duct 20 penetrates to the outside. In detail, the damper housing 110, the inclined surface 120, the damper wing 130, the heat insulating material 160, the magnet body 140, and the magnetic body 145 may be configured to include.

The damper housing 110 is configured in the form of a tubular body which is empty inside and open at both ends, and has an inclined surface 120, a damper wing 130, and a heat insulating material 160 therein, and a magnet body 140 at a lower end thereof. The magnet body buried portion 150 for storing is formed, and the damper blade 130 is provided with a magnetic body 145.

In addition, the damper housing 110 has an outward flange 170 formed along its outer circumferential surface, and the outward flange 170 is formed on an approximately central portion of the damper housing 110. Hereinafter, the front body of the damper housing 110 based on the outward flange 170 will be referred to as 'front end 111', and the rear body will be referred to as 'rear end 112'. The damper housing 110 has its front end 111 inserted into and fixed to the buried sleeve 45 of the wall 40, and the rear end 112 is connected to the discharging end 23 of the exhaust duct 20. The installation structure interposed between the wall 40 and the exhaust duct 20 is achieved.

On the other hand, the outward flange 170 is the damper housing 110 when the front end portion 111 of the damper housing 110 is engaged to the inner wall surface of the wall 40 when inserted to a predetermined depth of the wall 40 buried sleeve 45, the damper housing 110 ), Thereby preventing the damper housing 110 from being installed in the wall 40 while maintaining a proper embedded state.

The inclined surface 120 is in close contact with the inner periphery of the damper wing 130 and closes the inside of the tubular body corresponding to the exhaust passage to maintain airtightness, and is less than 90 ° (preferably around 60 °). It is formed along the inner circumferential surface of the damper housing 110 in a structure inclined upward into the building as a gradient. In addition, an air passage hole for air flow is formed in the center of the inclined surface 120.

The shape of the air passage port and the damper wing 130 of the inclined surface 120 is preferably formed in any one shape selected from circular, oval, U-shaped, according to the installation location and design structure of the ventilator 10 Of course, various changes are possible.

In addition, the inclined surface 120 forms a jaw structure protruding from the inner circumferential surface of the damper housing 110, and also serves as an external runoff flow preventing jaw that blocks external water from flowing into the building.

The damper wing 130 is mounted inside the damper housing 110 and rotates to be in close contact with the inclined surface 120 and spaced apart to perform the operation of opening and closing the interior of the damper housing 110. The damper blade 130 of the embodiment of FIG. 3 is hinged to the upper end of the damper housing 110 through the upper hinge 135, so that the vertical vertical direction about the axis of the hinge 135 can be axially rotated.

Accordingly, when the fan 10 is turned off, the damper housing 110 is closed by being lowered by its own weight to be in close contact with the inclined surface 120, and the exhaust duct 20 is turned on when the fan 10 is turned on. It is lifted by the wind pressure exhausted from the discharging end 23 of the end portion and opens the inside of the damper housing 110.

The heat insulator 160 is coated on the inner circumferential surfaces of the damper wing 130 and the damper housing 110 to correspond to a component that blocks outside air from entering the room through the exhaust duct 20.

First, the heat insulating material 161 attached to the damper wing 130 is preferably located on the outer side of the damper wing 130, which is in close contact with the inclined surface 120 of the inner side of the damper wing 130. In order to maintain airtightness when the ventilator 10 is turned off, the outer surface is coated with a heat insulator 161 to effectively block heat loss (or inflow of heat) due to outside air.

The heat insulating material 161 attached to the damper wing 130 should be made of a light material having excellent heat insulating properties. This is because the damper blade 130 is separated from the magnetic force by the exhaust wind pressure and operates to open the inside of the damper housing 110. Therefore, the light material means a light weight that does not interfere with the axial rotation operation of the damper wing 130 at least by the exhaust wind pressure. As the heat insulating material 161 meeting the above object, it is preferable to form one selected from expanded polystyrene (EPS) or polyurethane foam.

On the other hand, the heat insulating material 161 attached to the damper wing 130 is preferably formed in an arch shape to cover the entire surface of the outer surface of the damper wing 130, the curvature of the arch shape is the damper housing 110 It is more preferable to form similar to the curvature of the inner peripheral surface of the front end portion (111) of. This, while maximizing the thermal insulation effect by providing the insulating material 161 to the largest area and thick thickness, the circumferential portion of the insulating material 161 attached to the damper wing 130 during the axial rotation operation of the damper wing 130, the damper housing shear This is because it is advantageous to prevent interference with the inner circumferential surface of the part 111 and to sufficiently open the damper housing 110 by sufficiently rotating the damper blade 130.

Next, the heat insulating material 162 attached to the inner circumferential surface of the damper housing 110 is preferably located on the inner circumferential surface of the rear end 112 of the damper housing 110, which insulates the heat insulating material 160 on the inner circumferential surface of the front end portion 111. This is to prevent the case that the interference with the damper blade 130 occurs when attached to prevent the axial rotation operation of the damper blade. The heat insulator 162 attached to the damper housing 110 does not need to be particularly lightweight in consideration of the heat insulator 161 attached to the damper wing 130. However, the heat insulator having excellent heat insulation performance is better. Preferably, it is preferably formed of any one selected from expanded polystyrene (EPS) or polyurethane foam.

The magnet body 140 provided in the damper housing 110 provides a magnetic force to the magnetic body 145 provided in the damper wing 130 so that the damper wing 130 can be closely adhered to the inclined surface 120. Do it.

In the damper housing 110, the magnet body buried portion 150 is formed to fix the magnet body 140 to be in close contact with the rear surface of the inclined surface 120. The magnet body buried portion 150 is provided with a receiving space for embedding the magnet body 140, the receiving space is located behind the bottom side of the inclined surface (120). Therefore, the magnet body 140 stored in the magnet body buried part 150 is fixed to the rear of the inclined surface 120 to provide magnetic force to the magnetic body 145 provided in the damper wing 130.

On the other hand, the magnet body 140 may be fixed to the receiving space of the magnet body buried portion 150 through an adhesive or provided with an elastic piece inside the receiving space. When the elastic piece is formed, the magnet body 140 is accommodated by applying a load while pressing the magnet body 140 in one direction through an elastic restoring force generated in the elastic piece when the magnet body 140 is inserted into the receiving space. It may be possible to keep the insert firmly fixed in the space.

The magnetic body 145 is mounted on the damper wing 130, and specifically, the damper wing 130 is provided at a point opposite to the position of the magnet body 140 when the damper wing 130 is in close contact with the inclined surface 120. The magnetic body 145 provided in the damper wing 130 allows the damper wing 130 to be in close contact with the inclined surface 120 through a magnetic force with the magnet body 140 located behind the inclined surface 120.

The term 'magnetic body 145' used in the present invention refers to a magnetic material in a magnetic range, and all materials attached to the magnet are referred to as magnetic materials. Therefore, the magnetic body 145 of the present invention includes not only permanent magnets but also metals such as copper, nickel and iron.

Damper blade 130 of the embodiment of Figure 3 forms an insertion groove of the '' 'cross-sectional structure at the lower end of the damper wing 130 so that the magnetic body 145 is firmly coupled to the insertion groove in the form of a thin plate The magnetic body 145 was inserted and fixed. The metal thin plate accommodated in the insertion recess may be fixed through an interference fit method or fixed using an adhesive.

On the other hand, considering that the damper wing 130 is formed of a synthetic resin material (acrylics, etc.), it is a matter of course that the damper wing may be formed in a structure in which a metal sheet is embedded by insert injection.

6 is a view for explaining the tilt installation structure of the magnet damper 100 according to the present invention. Magnet damper 100 of the direct exhaust ventilation system according to the invention is characterized in that it is installed in the buried sleeve 45 of the wall 40, at this time for the air flow through the following features of another installation structure The opening area can be sufficiently secured.

Referring to FIG. 6, the magnet damper 100 has a rotation axis H1 (ie, a hinge axis) of the damper blade 130 in a range of 10 ° to 30 ° with respect to the gravity direction G (preferably around 15 °). It is characterized in that the installation is fixed to the wall 40 by the twisted angle (θ1).

That is, a conventional damper using gravity (ie, gravity damper) is typically installed so that the rotation axis of the damper blades orthogonal in the direction of about 90 ° to the direction of gravity (hereinafter referred to as 'orthogonal installation structure'), which is If the rotary shaft of the damper blade is installed at a great inclination in the direction perpendicular to the gravity direction, the fan is turned off after the shaft rotation of the damper blade (ie, damper housing opening) by the exhaust pressure when the fan is turned on. This is because the damper housing is not opened and the damper housing is opened and the damper housing is not opened, so the normal operation of the damper is impossible.

However, even if the magnet damper 100 of the present invention is installed in a state in which the rotary shaft H1 of the damper blade 130 is inclined greatly with respect to the gravity direction G, it is possible to ensure the normal lowering operation of the damper. This is because the axial rotation operation of the damper blade 130 for closing the damper housing 110 is generated by the magnetic force between the magnet body 140 and the magnetic body 145 when the (10) is off.

As described above, when the rotation axis of the damper blade 130 can be installed in a state substantially inclined with respect to the gravity direction by the damper configuration using magnetic force, and thus it is assumed that the same exhaust pressure is applied when the fan is turned on. The magnet damper 100 of the present invention has an increased axial rotation angle (that is, the degree of elevation) of the damper blade 130 compared to the conventional damper, so that it can open a larger area than the damper of the conventional orthogonal mounting structure. do.

7 is an example of installation of the direct ventilator ventilation system to which the magnet damper according to the present invention is applied. As illustrated in FIG. 7, the direct exhaust ventilating system of the present invention is a system in which a magnet damper 100 is interposed between an end outlet 23 of an exhaust duct 20 and a buried sleeve 45 of a wall 40. Has a structure. Preferably, the front end 111 of the magnet damper 100 is inserted and fixed to the buried sleeve 45 and the rear end 112 is connected to the discharging end 23 of the exhaust duct 20, the damper wing 130 ) Is fixed to the wall 40 in a state in which the axis of rotation (i.e., the hinge axis) is inclined by a range of 10 ° to 30 ° (preferably around 15 °) with respect to the gravity direction.

On the other hand, the outer vent cap 30 is inserted and fixed to the outside of the buried sleeve 45 of the wall 40, to prevent foreign substances including rain water from entering the room through the buried sleeve 45.

For reference, in the conventional direct ventilator ventilation system, the outside air is easily introduced into the room through the outlet of the outlet due to the installation structure in which the outlet of the exhaust duct is open to the outside through the landfill sleeve, and thus, the heat loss in winter Caused heating loss, and in summer, it caused cooling loss due to heat inflow. In addition, the exhaust duct is present in an open state to the outside bar easily condensation occurs inside the mold or bacteria to grow, there was a problem that the fine dust and noise flows intact.

However, in the direct ventilation system of the present invention, the magnet damper 100 is provided at a point where external air is initially introduced into the building (hereinafter, referred to as a “border part”) to achieve the following effects.

In other words, when the fan 10 is turned off, the reverse air and the inflow of outside air can be blocked, and further, the magnet body 140 pulls the metal sheet by the magnetic force when the fan 10 is turned off. By pulling the damper wing 130 is in close contact with the inclined surface 120, thereby further improving airtightness, it is also possible to prevent the lifting and impact noise of the damper wing 130 due to the wind acting on the boundary portion.

In addition, the damper blade 130 coated with the heat insulating material 161 is provided at the boundary portion, thereby exerting an excellent heat insulating effect in the conventional landfill sleeve region that is completely exposed to the outside air and the reverse wind. Cooling loss (or heating loss) and condensation can be greatly reduced.

In particular, the terminal discharge port 23 of the exhaust duct 20 is sufficient to secure the opening area for the air flow due to the characteristics that the indoor air sucked from the plurality of fans 10 are collected and exhausted to the outside, the present invention The magnet damper 100 blocks the outside air and the reverse wind through the damper wing 130 and prevents condensation. However, the magnetic damper 100 has sufficient inside of the damper housing 110 through an organic combination of a damper configuration and a tilting installation structure using magnetic force. Opening can be achieved.

In addition, only one magnet damper (100) installed in the boundary can block the inflow of the wind and the outside air, a conventional damper 100 to replace a plurality of electric dampers that were used for blocking the backwind in a single ventilation damper (100) Therefore, it is possible to reduce the construction cost of the direct ventilator ventilation system.

In addition, the magnetic damper 100 can replace the role of a separate accessory (for example, spiral duct, iron reducing, etc.), which is required to connect the exhaust duct end outlet to the landfill sleeve in the conventional direct ventilator ventilation system. It can also act as a factor to reduce the construction cost of direct ventilation system.

While the preferred embodiments of the present invention have been described and illustrated above using specific terms, such terms are used only for the purpose of clarifying the invention, and it is to be understood that the embodiment It will be obvious that various changes and modifications can be made without departing from the spirit and scope of the invention. Such modified embodiments should not be understood individually from the spirit and scope of the present invention, but should be regarded as being within the scope of the claims of the present invention.
