A box body having, a supply passage and an exhaust passage provided in the box body so as to intersect with each other by a heat exchanger provided between an inlet and an outlet, and the box body inside the heat exchange chamber And a blower that is detachably attached to the air supply passage and the exhaust passage to form a supply air flow or an exhaust flow, respectively, a blade casing provided in the air supply passage and the exhaust passage for the blower, and a main body in the heat exchange chamber. The heat exchanger is provided so that it can be inserted into and removed from the opening provided on the other side surface and exchanges heat between the air supply flow and the exhaust flow, and the blower has its electric motor with the heat exchanger removed from the heat exchange chamber. Are arranged so as to face the heat exchange chamber.

[Operation] In the present invention, the electric motor of the blower is arranged so as to face the heat exchange chamber, so that the electric motor faces the opening through the heat exchange chamber with the heat exchanger pulled out.

[Embodiment] FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is an exploded perspective view in which a lid (3) and a heat exchanger (12) are also removed, and FIG. It is a schematic sectional drawing which shows a flow, and (1)-(16) shows the same or equivalent part as the said prior art example in the figure. Reference numeral (20) is a partition plate provided so as to form the exhaust passage (8) and the air supply passage (9) in the box body (2), and the partition plates are provided at the mounting positions of the blowers (10) and (11). Is provided with a ventilation opening (22) through which the blade (21) penetrates, and a bypass passage (23) is provided between the side wall and the side wall of the box body (2) to form a bypass opening (24). . A heat exchange chamber (33) is formed by the partition plate (20) and the side wall of the box body provided with the opening (15).
(25) is a mounting member for mounting the electric motor (26) of the blower (10) (11), respectively, which can be attached to and detached from the opening (15) side of the L-shaped fixture (27) provided on the bottom plate of the box body (2). It is provided in. Reference numeral (28) is a U-shaped guide member for guiding the four corners of the heat exchanger (12) into the heat exchange chamber (33), one of which is a locking claw (provided on the box body (2). 29), and the opening (15) side is fixed with a screw (30).
Reference numeral (31) is a side wall which forms one side wall of the box body (2), and has an opening (15) formed therein and is detachably formed on the box body (2) by a screw (30). Reference numeral (32) is a damper for switching the bypass passage (23) and the exhaust passage (8).

The ventilation device with a heat exchanger configured as described above has a damper (32) in the air conditioning ventilation using the heat exchanger (12).
By operating the blowers (10) and (11) with the bypass opening (24) closed by the indoor air, the indoor air is sucked from the indoor suction port (4) through the duct as shown by the arrow A, and the heat is removed. It passes through the exchanger (12) and the exhaust passage (8) as shown by arrow B, is blown out from the outdoor air outlet (7) by the exhaust blower (10) as shown by arrow C, and is discharged to the outside through the duct. . The outdoor air is sucked through the duct from the outdoor suction port (5) as indicated by the arrow D, passes through the heat exchanger (12) and the air supply passageway (9) as indicated by the arrow E, and then the blower for air supply (9 ) From the indoor air outlet (6) to the arrow F
It is blown out and is supplied to the room through the duct.
At this time, in the heat exchanger (12), heat exchange is performed between the exhaust flow and the supply air flow to recover the exhaust heat and reduce the heating and cooling load. On the other hand, during the interim period that does not require air conditioning such as spring and autumn,
By rotating the damper (32) to open the bypass opening (24) and operating the respective blowers (10) and (11), the supply of outside air is performed in the same manner as the air conditioning and ventilation described above. The indoor air is sucked from the indoor suction port (4) through the duct, passes through the bypass passage (23), is blown out by the exhaust blower (10) such as the indoor air outlet, and is discharged to the outside through the duct. . Thus, since the exhaust flow does not pass through the heat exchanger (12), the resistance in the ventilation passage is reduced, and sufficient normal ventilation is performed. By performing air conditioning ventilation or normal ventilation as described above, the heat exchanger (1
2) becomes dirty and needs to be cleaned, but the box (1)
By removing the cover (14) provided on the side wall (31) and pulling out the heat exchanger (12) from the heat exchange chamber (33), it can be cleaned with a vacuum cleaner or the like. Since the insertion / removal is performed so as to be orthogonal to the forming direction of the suction ports (4) (5) and the air outlets (6) (7), the supply / exhaust pipes do not interfere. If the blower (10) (11) fails for some reason, remove the cover (14), remove the heat exchanger (12) from the heat exchange chamber (33), and remove the guide member (28). Remove the screws (30) and remove. Next, the attachment member (25) can be removed and the blowers (10) (11) can be taken out from the openings (15) for repair. In this way, since the blower is attached and detached from the opening (15) via the heat exchange chamber (33), the direction of insertion and removal of the heat exchanger (12) is the same, and the space can be provided at one place.

With this configuration, the space for inserting / removing heat exchangers, etc. and the inspection work can be centralized in one place, so the space is small as a whole, and the space around the box body is required to secure the space. No ceiling suspension bolts are installed, or restrictions such as thinning other ceiling suspension bolts by reinforcing certain ceiling suspension bolts are reduced, and there is only one inspection port on the ceiling surface, which does not require a large area. .

[Advantage of the Invention] As described above, the invention removes the mounting member (25) from the opening (15) side and opens the electric motor (26) with the opening (15).
Taken out from the side and repaired (no need for repair at all)
Since it is not necessary to remove a large and heavy casing or the like, the ceiling inspection port can be made small, and the removal work can be significantly facilitated, which is a practical effect.
