PROBLEM TO BE SOLVED: To solve the problem in which, a conventional heat exchange type ventilation device has a configuration which blocks an outdoor air suction port and an indoor air exhaust port so that dew condensation does not occur by cold air flowing in a body when outdoor air temperature is low, and a state of the indoor air being polluted continues.SOLUTION: An indoor air exhaust re-blowout port 17 is provided at one part of an interior case 13 for partitioning an exhaust blowing path 8, and also, an indoor air circulation port 6 is provided at one part of a front panel 14 having an indoor air suction port 5. Thus, an indoor air cleaning effect is acquired by the indoor air sucked from the indoor air suction port 5 passing through a filter 16 and being cleaned, and then blowing indoors again.SELECTED DRAWING: Figure 7 |
