- the mounting hole is a mounting hole 15 provided in the inner housing 20 (see also FIG. 3). .
- the component side mounting 50a is a screw receiver having a cylindrical shape, and the outer diameter on the tip side is gradually reduced.
- the mounting hole 15 includes a region where the inner diameter on the outer housing 10 (see FIG. 3) side is gradually reduced.
- the exhaust fan 60 (see FIG. 2) is preferably attached to the inner housing 20 in the same manner as the air supply fan 50 is attached.
- reference numeral “17a” indicates the housing-side first water retaining portion.
- each of the air supply blower 50 and the exhaust blower 60 is preferably arranged with the motor separated from both the inner housing 20 and the drain pan part, specifically, the first drain pan part 35.
- FIG. 9 is a cross-sectional view schematically showing another example of the heat exchange ventilator of the present invention
- FIG. 10 is another cross-sectional view schematically showing the heat exchange ventilator shown in FIG.
- the heat exchange ventilator 110A shown in these figures has substantially the same configuration as the heat exchange ventilator 110 shown in FIGS.
- the same constituent elements as those shown in FIG. 1, FIG. 2, or FIG. 3 are the same as those used in FIG. 1, FIG. 2, or FIG. Reference numerals are assigned and explanations thereof are omitted.
- hatching is partially omitted.
- the motor 43 of the air supply blower 50 is attached separately from the first drain pan portion 35 without contacting the first drain pan portion 35.
- reference numeral “45” indicates a sirocco fan constituting the air supply fan 50
- reference numeral “47” indicates a casing of the air supply fan 50
- reference numeral “53” indicates The motor of the exhaust fan 60 is shown.
- the motor 53 of the exhaust fan 60 is attached to the inner housing 20 without being in contact with the inner housing 20, specifically, separated from the back surface BP. ing.
- reference numeral “55” indicates a sirocco fan constituting the exhaust fan 60
- reference numeral “57” indicates a casing in the exhaust fan 60.
- the first drain pan regardless of whether the heat exchange ventilator 110A is installed on the ceiling or under the floor of the room. It is easy to prevent water accumulated in the portion 35 or water accumulated in the inner housing 20 from entering the motors 43 and 53. Further, the gap between the motor 43 of the air supply blower 50 and the first drain pan portion 35 and the gap between the motor 53 of the exhaust blower 60 and the back portion BP of the inner housing 20 are substantially the same ( (Interval), it becomes easy to ensure substantially the same safety when the heat exchange ventilator 110A is installed on the ceiling of the room and when it is installed under the floor.
- the heat exchange ventilator according to the present invention has a box-shaped inner housing that has one open surface and can retain water on the back surface side when the back surface facing the open surface is disposed downward, It is basically sufficient if it has a drain pan portion disposed on the open surface side of the inner housing in a direction opposite to the back surface of the housing, and the specific configuration of the heat exchange ventilator can be selected as appropriate. .
- the total number of the water retaining portions when a concave water retaining portion is provided is also a place where condensation easily occurs in the housing.
- the desired number can be 1 or more.
- the total number of drain pan portions arranged on the open surface side of the inner housing can be appropriately selected in consideration of the distribution of locations where condensation easily occurs in the housing.
- the air supply blower and the exhaust blower can be arranged in parallel on one of the outdoor side and the indoor side in the casing, or can be distributed on the outdoor side and the indoor side with the heat exchanger interposed therebetween. .
- the arrangement of the air supply blower and the exhaust air blower can be appropriately selected according to the form of each of the air supply and exhaust air passages to be formed in the housing.
- the moisture that can be stored in the housing is not only the water generated by condensation, but also the moisture (water droplets) contained in the room air, such as the moisture in the humidity atmosphere of the bathroom sucked into the housing from the indoor suction section. Water can be retained in the same way as the water produced.
- the heat exchange ventilator of the present invention can be variously modified, modified, combined, etc. in addition to those described above.
- the heat exchange ventilator of the present invention can be suitably used as a heat exchange ventilator for home use or business use.
