The outdoor air and the indoor air flown into the lower space is suctioned into the fan 330 through the common inlet 311, and thereafter discharged towards the first inlet 313 and the second inlet 315 in the upper space.
  • the second inlet 315 is blocked by the first damper 410, the discharged air is supplied into the inside of the room through the first outlet 120.
  • the first damper 410 closes the second flow passageway 2 formed in the lower space, as shown in FIG.3, when the ventilating system is operated in an air-exhaust mode. Then, as the fan 330 rotates, the indoor air flows into the lower space through the inlet 110 and the third flow passageway 3 and thereafter suctioned into the fan 330 through the common inlet 311. The air suctioned into the fan 330 is discharged towards the first inlet 313 and the second inlet 315 in the upper space. At this time, since the first inlet 313 and the second inlet 313 are both opened, the air discharged towards the first inlet 313 is supplied into the inside of the room, and air discharged towards the second outlet 120 is exhausted to the outside through the first flow passageway 1.

  • a good ventilating efficiency can not be achieved through the first damper 410 only.
  • the indoor air, together with the outdoor air is flown into the case 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.
  • part of the indoor air flown into the case 100 is exhausted into the outside of the room, and the remaining portion thereof is supplied back into the inside of the room.
  • the case 100 is provided with a second damper 420 and a third damper 430 respectively in the inlet 110 and the outlet 120, as shown in FIGS. 1 and 3.
  • the second damper 420 is provided in the case 100 so as to open and close the inlet 110. More specifically, the second damper 420 closes the inlet 110 when the ventilating system is operated in an air-supply mode to supply the outdoor air inside the room, as shown in FIG. 1. As shown in FIG. 3, in an air-exhaust mode to exhaust the indoor air into the outside of the room, the second damper opens the inlet 110.
  • the third damper 430 is provided in the case 100 so as to open and close the outlet 120. More specifically, the third damper 430 opens the outlet 120 in the air-supply mode as shown in FIG. 1, and closes the outlet 120 in the air-exhaust mode as shown in FIG. 3.
  • a heater 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.
  • a filter 520 is further provided in the lower space of the case, specifically at the place where the second flow passageway 2 and the first flow passageway 1, as shown in FIGS. 1 and 3. The filter 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.
  • 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.
  • the first damper 410 blocks the duct 200 from the upper space where the fan 330 is provided, the second damper 420 blocks the inlet 110, and the third damper 430 opens the outlet 120. If the fan 330 is operated, the outdoor air is flown into the case 100 through the first flow passageway 1. At this time, in case of winter-time, the heater 510 heats up the outdoor air passing through the duct 200.
  • the outdoor air entered into the case 100 flows into the second flow passageway 2 formed in the lower space and is purified by the filter 520 installed in the second flow passageway 2.
  • the outdoor air flowing along the second flow passageway 2 is suctioned in the axial direction of the fan 330 through the common inlet 311.
  • the fan 330 discharges the suctioned outdoor air towards the outlet 120 and the duct 200.
  • the first damper 410 blocks the outdoor air moving towards the duct 200 from the upper space, the outdoor air discharged from the fan 330 is supplied, in its entirety, into the inside of the room through the outlet 120.
  • the first damper 410 blocks the duct 200 from the lower space where the filter 520 is provided, and the second damper 420 opens the inlet 110 and closes the outlet 120.
  • the fan 330 If the fan 330 is operated, the indoor air is flown into the case 100 through the inlet 110. The indoor air entered into the case 100 moves along the second flow passageway 2 and flows towards the fan 330 through the common inlet 311. Then, the fan 330 discharges the indoor air towards the duct 200 and the outlet 120. At this time, the outlet 120 is closed by the third damper 430 and thus the indoor air flown into the fan 330 is discharged, in its entirety, into the outside of the room through the duct 200, as shown in FIG. 3.
  • FIGS. 4 to 7 illustrate a ventilating system according to a second embodiment of the invention.
  • 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, the case 110 is provided in the bottom face of the case, but in this embodiment the inlet 110 is provided in a lateral face of the case 100.
  • the structure of the second embodiment will be described, focusing on features different from the first embodiment.
  • the inlet 110 is provided at the lower side of a lateral face of the case 110, and the outlet is provided at the upper side of a lateral face of the case 100.

  • the first damper 410 fluid-communicates the duct 200 with the lower space of the case 100 and prevents the air discharged from the fan 330 from entering the duct 200, as illustrated in FIG. 4.
  • the fourth damper 440 opens the outlet 120 and closes the inlet 110.
  • the first damper 410 blocks the lower space of the case 100 from the duct 200 and guides the air discharged from the fan 330 into the duct 200, as shown in FIG. 6.
