Abstract

PURPOSE: To improve the heat exchange efficiency of a ventilator equipped with a heat exchanger by employing such a suction air passage as is smaller in cross-sectional area than a discharge air passage.
CONSTITUTION: A ventilator 1 consists of a blower body 2 and a decorative cover body 3. The blower body 2 is divided by a partition 4 into a discharge air passage 5 and a suction air passage 6. Partitions 10, 11 having air vents 12 are provided in the passages 5, 6 such that the partitions 10, 11 are parallel to the partition 4 to face fans 8, 9, respectively. An electric motor 7 for coaxially driving the fans 8, 9 is fixed in the partition 4 such that the electric motor 7 is projected more into the suction air passage 6 than into the discharge air passage 5 to thereby render the cross-sectional area of the suction air passage 6 smaller. A heat exchanger 15 rotatable by an electric motor 17 is provided in the decorative cover body 3. Thus, the flow rate of suction air is reduced as compared with that of discharge air. As a result, the heat exchange efficiency can be improved, and the manufacturing cost can be reduced.
