The conventional intelligent ventilation control system means an intelligent ventilation control system having an energy saving function that can reduce the exhaust air pressure and reduce the power consumption of the fan motor by adjusting the flow angle of the filter based on the freshness of outdoor air.

1 is a schematic perspective view of a prior art intelligent ventilation control system, as taught by the same inventor (Application No. 10-2007-0116973). 1, the ventilation control system includes a pre-filter 130 disposed at the inlet 110 and a pre-filter 130 disposed at the inlet 110. The pre- The first and second composite filters 140 and 150 are provided at the rear of the first and second filters 140 and 150, respectively. The suction pipe 100 and the exhaust pipe 180 of a predetermined shape are formed by controlling the discharge pressure of the rotation angle control and the filtering of the first and second composite filters 140 and 150 and between the suction pipe 100 and the exhaust pipe 180 A first fan motor 170 for controlling the internal suction pressure of the suction pipe 100 in accordance with an external control signal and a second fan 170 for controlling the rotation angle of the first and second composite filters 140 and 150, And two rotation motors 145 and 155. [

The conventional intelligent ventilation control system measures the freshness of outdoor air with an outdoor air sensor and controls the fan motor 170 and the first and second rotary motors 145 and 155 in conjunction with the measurement data. That is, when there is no dust in the outside outdoor air and there is no need for filtering, the first and second composite filters 140 and 150 are rotated in the direction of 90 degrees so that the intake air 120 is separated from the first and second composite filters 140 , And 150 (pass-through). When there is a lot of dust again in the outdoor air, the first and second composite filters 140 and 150 are returned to their original positions, and the outdoor air is filtered and discharged.

However, the conventional intelligent ventilation control system has the following problems. In the process of rotating the first and second composite filters 140 and 150 in the direction of 90 degrees so as to allow fresh outside air to pass therethrough, existing dust and foreign substances on the first and second composite filters 140 and 150 There is a problem that it is re-scattered together with the air and flows into the room. That is, fresh air from the outside is rather contaminated due to dust re-scattering.

SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an automatic opening / closing device for a rotating filter which prevents dust from being re-dispersed during the rotation of the filter .

A second object of the present invention is to provide an automatic opening / closing device for a rotating filter which can operate by interlocking the rotation of the filter and the automatic opening / closing of the filter.

The above object of the present invention can also be achieved by providing a frame 310 installed on one surface of a rotatable filter 200; Blocking means for opening and closing the filter 200 while being fixed to the frame 310 at one end and moving along the frame 310 at the other end; And a conveying means capable of reciprocating the shut-off means.

In addition, the shielding means may include a plurality of wrinkles 325 and may be deployed or folded around the wrinkles 325.

Alternatively, the shielding means comprises a slide groove 340 formed along the longitudinal direction on the frame 310; A slider 350 which is freely slidable within the slide groove 340; And a blocking film 320 fixed to one end of the slider 350.

Further, the conveying means includes an elevating member (330) provided at the other end of the shielding means; A pulley installed in at least two of the corner areas of the frame 310; A motor coupled to at least one of the pulleys; And a transmission means for connecting the elevating member and the pulley to transmit the power.

Further, the elevating member 330 is installed at the other end of the shielding means in the transverse direction, and at least one of both ends of the elevating member 330 is connected to the transmitting means.

The pulleys also include an upper pulley installed at at least one of the upper edge regions of the frame 310; And a lower pulley installed in at least one of the lower edge regions of the frame 310.

Also, the pulleys include a first upper pulley 406 and a second upper pulley 416, which are respectively installed at both ends of the upper edge region of the frame 310; And a first lower pulley 404 and a second lower pulley 414 installed at both ends of the lower edge region of the frame 310. The motor is connected to the first upper pulley 406 and the first lower pulley A first motor 400 installed at least one of the first and second motors 400 and 404; And a second motor 410 installed on at least one of the second upper pulley 416 and the second lower pulley 414.

Further, the transmission means is at least one of a wire, a belt, a gear, and a chain.

Further, the motor may be a servomotor or a stepping motor capable of normal / reverse rotation.

In addition, as the filter 200 is rotated from its upright position to its horizontal position, the motor is controlled to unfold the barrier membrane means to close the filter 200.

Further, as the filter 200 is rotated from the horizontal state to the upright state, the motor can be controlled to open the filter 200 by folding the barrier membrane means.

According to an embodiment of the present invention, when the filter is rotated to supply fresh outside air directly to the room or underground, the filter can be blocked to prevent dust from being re-scattered. Therefore, there is an advantage that fresh air can be supplied without being contaminated.

Example  Configuration

Hereinafter, with reference to FIGS. 2A to 4, a detailed structure of an automatic opening / closing device for a rotating filter according to an embodiment of the present invention will be described in detail.

The filter 200 functions to remove particles such as dust from the air introduced into one side. This filter 200 has a substantially rectangular shape and has a rigid frame around it to maintain its shape.

The drive motor 220 is installed in a vertical member (or frame) of the filter 200 to rotate the filter 200 between a vertical position and a horizontal position. The rotating shaft 210 is installed at a position facing the driving motor 220 and serves to hold both sides of the filter 200. For this purpose, the rotary shaft 210 is formed in the same axial direction as the driving motor 220. The filter 200 can be stably rotated by the driving motor 220 and the rotating shaft 210.

The filter opening / closing device 300 is attached to one surface of the filter 200, and is positioned upstream of the introduced air so as to contact the air before the filter 200. The filter opening / closing device 300 rotates together with the filter 200 as it rotates (or rotates). The filter opening / closing apparatus 300 mainly comprises a frame 310 and a shielding film 320.

The frame 310 is a rectangular metal frame, and is composed of two horizontal members and two vertical members. Each of the pair of vertical members of the frame 310 is provided with a slide groove 340 along the longitudinal direction and a slider 350 is inserted into each slide groove 340 to be movable along the slide groove 340 . The first and second cables 470 and 480 are provided in the slide groove 340 and are movable. First and second upper pulleys 406 and 416 are rotatably provided at the upper end of the slide groove 340 and first and second lower pulleys 404 and 414 are rotatably provided at the lower end of the slide groove 340. [ do.

The slider 350 has a configuration in which one end is a disk shape, an intermediate portion passes through the slide groove 340, and a protrusion 355 is formed at the other end to fasten the blocking film 320. The configuration of the slide groove 340 and the slider 350 may be similar to that of a curtain or a blind. The configurations of the first and second cables 470 and 480 and the pulleys may be similar to those of the electric curtain or the electric blind. A plurality of sliders 350 are provided in the slide grooves 340 and a size and a material (for example, aluminum or synthetic resin) can be selected so as to be slidable with as little friction as possible.

The light shielding film 320 is preferably made of a light and thin synthetic resin material (e.g., vinyl) without passing through the air. The blocking film 320 has an area and a shape (rectangle) enough to cover at least the frame 310 at the time of unfolding. The blocking film 320 is sufficiently thin and can be tightly folded.

The shielding film 320 may form a plurality of wrinkles 325 in the transverse direction so that it can be easily folded or unfolded around the wrinkles 325. The cross section of the corrugated portion 325 may have a triangular waveform, but various shapes such as a rounded waveform can be changed.

The protrusion 355 of the slider 350 is fastened to both ends of the wrinkle portion 325 so that the blocking film 320 can be folded or unfolded along the slide groove 340. In an embodiment, the coupling between the protrusions 355 is illustrated. However, the corrugated portion 325 and the slider 350 can be combined using various methods such as clips, sewing, bonding, tacking, and stapling.

The lower part of the blocking film 320 is fixed to the lower horizontal member of the frame 310 and the elevating member 330 is installed on the upper part of the blocking film 320. The lifting member 330 is made of metal or synthetic resin and has a length longer than the width of the blocking film 320. First and second holes 450 and 460 are formed at both ends of the lifting member 330 to connect the first and second cables 470 and 480, respectively. The shielding film 320 is connected to the intermediate region of the lifting member 330 so that the shielding film 320 can be folded or unfolded.

The first and second lower pulleys 404 and 414 are rotatably installed in the lower edge region of the frame 310, respectively. The first and second lower pulleys 404 and 414 are respectively connected to the first and second motors 400 and 410 to serve as drive pulleys. The first and second motors 400 and 410 may be a stepping motor, a servo motor, or a constant speed motor. That is, the first motor 400 is connected to the first lower pulley 404 through the first drive shaft 402 and the second motor 410 is connected to the second lower pulley 414 ). A first cable 470 is connected to the first lower pulley 404 to transmit power. To this end, the first cable 470 may be wound several times on the first lower pulley 404 or may be connected by a knot. The second lower pulley 414 and the second cable 480 have the same structure.

The first and second upper pulleys 406 and 416 are rotatably installed in the upper edge region of the frame 310, respectively. The first and second upper pulleys 406 and 416 serve as a driven pulley. A first cable 470 is connected to the first upper pulley 406 to serve as an idle pulley. The second upper pulley 416 and the second cable 480 have the same structure.

5 is a side view when the filter opening / closing device according to the embodiment of the present invention is in an upright state. As shown in FIG. 5, the filter 200 and the filter opening / closing device 300 are integrated and installed in the suction pipe 100. The filter 200 and the filter opening / closing device 300 cover the cross section of the suction pipe 100 in an upright state so that the air passing through without filtration is minimized.

Example  action

Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.

5 is a side view when the filter opening / closing device according to the embodiment of the present invention is in an upright state. 5, the filter 200 and the filter opening and closing device 300 are in an upright state, and the intake air 120 is mostly filtered through the filter 200 to become the filtered air 160. At this time, the blocking film 320 keeps a tightly folded state at the lower portion of the frame 310. The tightly folded shielding film 320a blocks the filter area of the filter 200 to a minimum and does not greatly affect the overall filter performance. Further, even if the intake air 120 hits the collapsed shielding film 320a, it is not spread by the frictional force between the motor and the pulley.

6 is a side view of the filter opening and closing device of Fig. 5 when rotated counterclockwise by 30 [deg.]. The filter 200 and the filter opening / closing device 300 are inclined by the drive motor 220, as shown in Fig. Then, the first and second motors 400 and 410 are simultaneously rotated. Then, the first and second lower pulleys 404 and 414 rotate through the first and second drive shafts 402 and 412. As a result, the first and second cables 470 and 480 rotate to raise the lifting member 330.

Then, the blocking film 320 connected to the lifting member 330 is slightly unfolded. At this time, the wrinkle portion 325 is spread out, and the slider 350 moves along the slide groove 340 to guide the spread. For ease of understanding, the arrow 230 indicates the rotation of the filter by the rotation of the drive motor 220, and the arrow 240 indicates the rise of the blocking film 320.

7 is a side view of the filter opening and closing apparatus of Fig. 5 when rotated counterclockwise by 60 [deg.]. 7, as the filter 200 and the filter opening / closing device 300 are further tilted by the driving motor 220, the air 250 passing through the filter 200 without passing through the filter 200 is gradually increased do. This is more effective when the outside air is clean. In addition, the first and second motors 400 and 410 continue to rotate so that the shielding film 320 is in a state of the shielding film 320b which is further spread than in FIG. 7, most of the intake air 120 becomes the air 250 that passes through the cut-off membrane 320b and passes without filtration. Accordingly, it is possible to prevent a considerable part of dust scattering on the filter 200 from being re-scattered.

8 is a side view of the filter opening and closing apparatus of Fig. As shown in Fig. 8, the filter 200 and the filter opening / closing device 300 maintain a horizontal state. At this time, all of the intake air 120 does not pass through the filter 200, but passes through the intake pipe 100 as it is. In addition, the blocking layer 320 also becomes a completely opened blocking layer 320c to cover the entire surface of the filter 200. [ As a result, the clean fresh intake air 120 flows into the room or the underground without passing through the filter 200. Also, since the front surface of the filter 200 is completely blocked by the shielding film 320c, the dust of the filter 200 is left in the filter 200 without being re-scattered. Through the above process, the folded shielding film 320a can be switched to the shielding film 320c completely opened by the control of the motor.

If the completely opened barrier film 320c needs to be folded again, the processes of FIGS. 5 to 8 may be performed in reverse order. That is, the first and second motors 400 and 410 rotate in a direction opposite to the direction of rotation when the elevating member 330 is raised. The first and second motors 400 and 410 rotate in a reverse direction until they are in an upright state as shown in FIG. A control circuit, a sensor, and the like for controlling the rotation of the first and second motors 400 and 410 can be easily constructed by those skilled in the art, so a detailed description thereof will be omitted.

Variation example

In an embodiment of the present invention, a barrier layer 320 is disclosed. However, in various variations, it may be possible to apply a resistance blade (wing) to the barrier layer 320 so that it is resistant to wind and spreads faster.

Further, the first and second motors 400 and 410 may be configured to operate with only one motor, or a motor mounted below may be mounted on the upper portion.

In addition, although the cable is shown as a transmission means for transmitting the driving force of the motor to the shielding film, the cable may be replaced with a wire, a belt, a gear, a chain, or the like. For example, a sprocket can be used instead of a pulley when replacing with a chain, and multiple gear rows can be used when replacing gears.

In addition, a rotary motor-driven type linear motor can also be used as a driving source for an elevating motion.

Although the present invention has been described in connection with the preferred embodiments set forth above, it will be readily appreciated by those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that all modifications are within the scope of the appended claims.
