- FIGS. 1 to 3 illustrate a ventilating system according to a first embodiment of the invention. Referring to FIGS. 1 to 3, the ventilating system of the invention is provided with a
case 100, which is to be placed in the inside of a room. For example, thecase 100 has an angular corner so as to be installed in the corner of aceiling 10, as shown inFIG. 2 . Thecase 100 is installed in such a manner that the top face of thecase 100 is closely contacted with theceiling 10, and the two lateral face thereof extended from the angular corner are closely contacted with awall 20 of the inside of the room. This structure is very useful in case where between theceiling 10 and the upstairs bottom face does not provide an adequate space to install a ventilation system case and ducts. - The
case 100 is provided with aninlet 110 and anoutlet 120, which are fluid-communicated with the interior of the room. In the ventilating system of the first embodiment, theinlet 110 is provided in the bottom face of thecase 100 as shown inFIG. 1 , and theoutlet 120 is provided in a side face of thecase 100 so as to face the interior of the room as shown inFIG. 2 . In thecase 100, the side face facing the interior of the room may have a rounded face, and theoutlet 120 is disposed such that air can be supplied into the inside of the room in various directions. - As described above, the
case 100 is fluid-communicatively connected with the interior of the room through theinlet 110 and theoutlet 120 and fluid-communicatively connected with the outside of the room through afirst flow passageway 1, as illustrated inFIGS. 1 and 3 . Thefirst flow passageway 1 is defined by aduct 200 installed so as to pass through thewall 20, and one end thereof is fluid-communicated, for example, with the outside of the room and the other end thereof is connected with thecase 100. At one end of theduct 200 is provided anopening 210 and a grill, through which theduct 200 is fluid-communicated with the outside of the room. The other end of theduct 200 is formed in such a way that its diameter is expanded gradually towards thecase 100. Along thefirst flow passageway 1 defined by theduct 200, the outdoor air is flown inside thecase 100, or the indoor air introduced into thecase 100 through theinlet 110 is exhausted to the outside of the room. - Inside the
case 100 is formed asecond flow passageway 2 through which the outdoor air entered into thecase 100 through theduct 100 is guided into the inside of the room, and athird flow passageway 3 through which the indoor air entered into thecase 100 through theinlet 110 is guided into theduct 200. Here, thesecond flow passageway 2 fluid-communicates thefirst flow passageway 1 with theoutlet 120, and thethird flow passageway 3 fluid-communicates thefirst flow passageway 1 with theinlet 110. - As shown in
FIGS. 1 and 3 , the second andthird flow passageways case 100. In addition, afan unit 300 is provided at the position where the second andthird flow passageways fan unit 300 functions to suction the outdoor air through the first andsecond flow passageways third flow passageway 3 and exhaust it to the outside of the room through thefirst flow passageway 1. Thefan unit 300 will be further explained below, with reference toFIGS. 1 and 3 . - The
fan unit 300 is formed of ascroll casing 310 and afan 330 provided inside thescroll casing 310. The scroll-casing 310 is provided, for example, upwards of the inside of thecase 100, and the bottom face of thescroll casing 310 divides the inside space of thecase 100 into a lower space and an upper space. Here, the upper space and the lower space may be divided by apartition plate 350, instead of thescroll casing 310. In this case, thepartition plate 350 is installed in such a way as to cross horizontally the inside of thecase 100 and thescroll casing 310 is mounted approximately at the middle of thepartition wall 350. - On the other hand, the lower space is fluid-communicated with the
inlet 110 and the upper space is fluid-communicated with theoutlet 120. In addition, both the upper space and the lower space are fluid-communicated with theduct 200 defining thefirst flow passageway 1. The upper space and the lower space is not completely partitioned, but fluid-communicated with each other through acommon inlet 311 formed approximately at the center of thescroll casing 310. Here, thesecond flow passageway 2 for guiding the outdoor air into the inside of the room is led from the place where thefirst flow passageway 1 and the lower space meet each other, passing thecommon inlet 311, until theoutlet 120. Thethird flow passageway 3 for guiding the indoor air into the outside of the room is led from theinlet 110 via thecommon inlet 311 until the place where thefirst flow passageway 1 and the upper space meet each other. - The
fan 330 is provided inside thecase 100 and functions to suction the air in the lower space and discharge into the upper space. More specifically, thefan 330 is disposed in the upper space and installed such that the air in the lower space is suctioned along the axial direction through thecommon inlet 311, where the second andthird flow passageways scroll casing 310 surrounds the side face of thefan 330 provided in the upper space, and also guides the air, which is discharged along the radial direction from thefan 330, towards theoutlet 120 of thecase 100 and thefirst duct 200. For this purpose, in the lateral side of the scroll casing 31 are provided afirst outlet 313 fluid-communicated with theoutlet 120 of thecase 100 and asecond outlet 315 fluid-communicated with thefirst duct 200. - Between the
fan unit 300 and the exterior of the room is provided afirst damper 410, which fluid-communicates theduct 200 alternately with the upper space or the lower space. More specifically, thefirst damper 410 is mounted on thepartition plate 350 or thescroll casing 310, and functions to open alternately thesecond flow passageway 2 and thethird flow passageway 3. As illustrated inFIGS. 1 and 3 , thefirst damper 410 is pivotably installed in thepartition plate 350 and turned about a hinge to thereby open alternately thesecond flow passageway 2 and thethird flow passageway 3. However, the invention is not limited to the above illustration. Alternatively, thepartition plate 350 may be provided with a plurality of louvers installed in the upper and lower sides thereof so as to open selectively thesecond outlet 120 and thesecond flow passageway 2. - The
first damper 410 installed as above closes thethird flow passageway 3 formed in the upper space when the ventilating system is operated in an air-supply mode, as shown inFIG. 1 . Then, as thefan 330 rotates, the outdoor air flows into the lower space of thecase 100 through the first andsecond flow passageways inlet 110 and thethird flow passageway 3. The outdoor air and the indoor air flown into the lower space is suctioned into thefan 330 through thecommon inlet 311, and thereafter discharged towards thefirst inlet 313 and thesecond inlet 315 in the upper space. Here, since thesecond inlet 315 is blocked by thefirst damper 410, the discharged air is supplied into the inside of the room through thefirst outlet 120. - The
first damper 410 closes thesecond flow passageway 2 formed in the lower space, as shown inFIG. 3 , when the ventilating system is operated in an air-exhaust mode. Then, as thefan 330 rotates, the indoor air flows into the lower space through theinlet 110 and thethird flow passageway 3 and thereafter suctioned into thefan 330 through thecommon inlet 311. The air suctioned into thefan 330 is discharged towards thefirst inlet 313 and thesecond inlet 315 in the upper space. At this time, since thefirst inlet 313 and thesecond inlet 313 are both opened, the air discharged towards thefirst inlet 313 is supplied into the inside of the room, and air discharged towards thesecond outlet 120 is exhausted to the outside through thefirst flow passageway 1. - As described above, the
first damper 410 controls the flow of the indoor air and the outdoor air when the ventilating system of the invention is operated in an air-supply mode and an air-exhaust mode. However, a good ventilating efficiency can not be achieved through thefirst damper 410 only. In other words, as described above, when in the air-supply mode, the indoor air, together with the outdoor air, is flown into thecase 100 and supplied into the interior of the room, and thus a large amount of outdoor air can not be introduced into the inside of the room within a short period of time. In addition, when in the air-exhaust mode, part of the indoor air flown into thecase 100 is exhausted into the outside of the room, and the remaining portion thereof is supplied back into the inside of the room. Accordingly, a large amount of indoor air cannot be exhausted to the outside in a short period of time. Thus, in order to solve this problem to thereby achieve a high ventilation efficiency, thecase 100 is provided with asecond damper 420 and athird damper 430 respectively in theinlet 110 and theoutlet 120, as shown inFIGS. 1 and 3 . - The
second damper 420 is provided in thecase 100 so as to open and close theinlet 110. More specifically, thesecond damper 420 closes theinlet 110 when the ventilating system is operated in an air-supply mode to supply the outdoor air inside the room, as shown inFIG. 1 . As shown inFIG. 3 , in an air-exhaust mode to exhaust the indoor air into the outside of the room, the second damper opens theinlet 110. In addition, thethird damper 430 is provided in thecase 100 so as to open and close theoutlet 120. More specifically, thethird damper 430 opens theoutlet 120 in the air-supply mode as shown inFIG. 1 , and closes theoutlet 120 in the air-exhaust mode as shown inFIG. 3 . - On the other hand, inside the
duct 200, i.e., in thefirst flow passageway 1 is further provided aheater 510, as shown inFIGS. 1 and 3 . Theheater 510 heats the outdoor air being supplied into the inside of a room in winter time when the temperature of the outdoor air is lower, thereby enabling to supply an air having a temperature appropriate to the indoor. Furthermore, afilter 520 is further provided in the lower space of the case, specifically at the place where thesecond flow passageway 2 and thefirst flow passageway 1, as shown inFIGS. 1 and 3 . Thefilter 520 functions to filter the outdoor air being supplied into the inside of a room, when the ventilating system of the invention is operated in an air-supply mode. - As described above, the ventilating system of first embodiment having the above construction is operated in an air-supply mode and in an air-exhaust mode, which will be further explained below, in greater detail.
- In the air-supply mode, as shown in
FIG. 1 , thefirst damper 410 blocks theduct 200 from the upper space where thefan 330 is provided, thesecond damper 420 blocks theinlet 110, and thethird damper 430 opens theoutlet 120. If thefan 330 is operated, the outdoor air is flown into thecase 100 through thefirst flow passageway 1. At this time, in case of winter-time, theheater 510 heats up the outdoor air passing through theduct 200. - Due to the
first damper 410, the outdoor air entered into thecase 100 flows into thesecond flow passageway 2 formed in the lower space and is purified by thefilter 520 installed in thesecond flow passageway 2. In addition, the outdoor air flowing along thesecond flow passageway 2 is suctioned in the axial direction of thefan 330 through thecommon inlet 311. Then, thefan 330 discharges the suctioned outdoor air towards theoutlet 120 and theduct 200. Here, since thefirst damper 410 blocks the outdoor air moving towards theduct 200 from the upper space, the outdoor air discharged from thefan 330 is supplied, in its entirety, into the inside of the room through theoutlet 120. - In the air-exhaust mode, as shown in
FIG. 3 , thefirst damper 410 blocks theduct 200 from the lower space where thefilter 520 is provided, and thesecond damper 420 opens theinlet 110 and closes theoutlet 120. If thefan 330 is operated, the indoor air is flown into thecase 100 through theinlet 110. The indoor air entered into thecase 100 moves along thesecond flow passageway 2 and flows towards thefan 330 through thecommon inlet 311. Then, thefan 330 discharges the indoor air towards theduct 200 and theoutlet 120. At this time, theoutlet 120 is closed by thethird damper 430 and thus the indoor air flown into thefan 330 is discharged, in its entirety, into the outside of the room through theduct 200, as shown inFIG. 3 . - FIGS. 4 to 7 illustrate a ventilating system according to a second embodiment of the invention. As shown in the figures, the ventilating system of the second embodiment has generally the same structure as that of the first embodiment, excepting the
inlet 110 of the case. That is, in the previous embodiment, thecase 110 is provided in the bottom face of the case, but in this embodiment theinlet 110 is provided in a lateral face of thecase 100. Hereafter, the structure of the second embodiment will be described, focusing on features different from the first embodiment. - As shown in
FIGS. 4 and 5 , theinlet 110 is provided at the lower side of a lateral face of thecase 110, and the outlet is provided at the upper side of a lateral face of thecase 100. Theinlet 110 and theoutlet 120 are both fluid-communicated with the inside of a room and separated from each other by thescroll casing 310 or thepartition plate 350. In the ventilating system of the second embodiment, theinlet 110 and theoutlet 120 are installed adjacent to each other in the same face of thecase 100. Therefore, in the ventilating system according to the second embodiment, theinlet 110 and theoutlet 120 can be opened alternately by a single damper, dissimilar to the first embodiment. For this purpose, inside thecase 100 is provided an additional damper, i.e., afourth damper 440 for opening alternately theoutlet 120 and theinlet 110. On the other hand, theoutlet 120 and theinlet 110 may be configured so as to be opened and closed separately by the two dampers, similar to the first embodiment. - In an air-supply mode, the
first damper 410 fluid-communicates theduct 200 with the lower space of thecase 100 and prevents the air discharged from thefan 330 from entering theduct 200, as illustrated inFIG. 4 . As shown inFIGS. 4 and 5 , thefourth damper 440 opens theoutlet 120 and closes theinlet 110. When thefan unit 300 operates, the outdoor air are supplied into the inside of the room through theoutlet 120 provided in a lateral face of thecase 100 via theduct 200, the lower space, and thecommon inlet 311, as illustrated inFIG. 5 . - In an air-exhaust mode, the
first damper 410 blocks the lower space of thecase 100 from theduct 200 and guides the air discharged from thefan 330 into theduct 200, as shown inFIG. 6 . In addition, thefourth damper 440 closes theoutlet 120 and opens theinlet 110, as shown inFIGS. 6 and 7 . When thefan unit 300 is operated, the indoor air is flown into thecase 100 through theinlet 110 provided in a lateral face of thecase 100 and discharged into the outside of the room through thethird flow passageway 3, thecommon inlet 311, the upper space, and theduct 200. - As described above, in the ventilating system of the invention, a single fan unit is used for supplying the outdoor air into the inside of a room or exhausting the indoor air into the outside of the room. In addition, according to the invention, a single duct is connected to the case thereof so as to alternately supply or exhaust the air. Therefore, the present invention can provide a small and less expensive ventilating system, as compared with the conventional ones. In addition, the noise and power consumption by the fan can be reduced, as compared with the convention ones having plural fans. Furthermore, the ventilating system of the invention has a heater and a filter. Thus, even in winter time, an air heated up to an appropriate temperature can be supplied, and a purified air can be supplied to the inside of the room, thereby providing pleasant indoor environments.
- The forgoing embodiments are merely exemplary and are not to be construed as limiting the present invention. The present teachings can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
