ている。[Prior Art] The above-mentioned conventional ventilation system of this kind is, for example,
The configuration is as disclosed in Japanese Patent No. 2125. That is, the rear interior is divided into an upper exhaust passage and a lower intake passage, and the rear part of the outer casing has an indoor air discharge port communicating with the exhaust passage and an outside air intake port communicating with the intake passage. Functional parts such as heat exchange elements and blowers are placed inside. An outside air discharge port for blowing outside air between the floors and a downward indoor air suction port are provided at the front of the outer casing, and the front ends of the exhaust passage and intake passage in the outer casing are connected to the outside air outlet and the indoor air intake. A cross-flow type square columnar heat exchange element is assembled between the air inlet and the air suction port. The exhaust passage includes an exhaust air blower that forms an exhaust flow from the indoor air inlet to the indoor air outlet via one air passage of the heat exchange element.
Further, each of the intake passages includes an intake blower that forms an intake air flow from the outside air intake port to the outside air discharge port via the other air passage of the heat exchange element. Air filters are attached to the air inflow sides of the heat exchange elements, respectively. A cover is attached to the outer casing so as to cover the opening, and this cover constitutes a part of the outer casing and performs functions such as securing an air passage. In addition, the hanging metal fittings for hanging the whole thing along the ceiling are tightened and fixed to the outer casing in an exposed state.

なる。The ceiling-mounted heat exchange ventilation system of this example configured as described above can simultaneously exhaust indoor air to the outdoors and supply outdoor air indoors through the heat exchange element 10 on the ceiling side. It is possible to perform ventilation that suppresses fluctuations in state variables such as temperature. In addition, when heat exchange ventilation is not required, such as during the middle of the season, or when you want to quickly exhaust cigarette smoke, etc., the damper 20 can be closed and the switching damper 13 can be opened to open the bypass passage 3. The indoor air suction port 9 and the suction side of the exhaust blower 11 are connected through the bypass passage 3, and exhaust can be exhausted without passing through the heat exchange element 10.

８の内部が見えることがなく、意匠性も向上する。The outside air after passing through the heat exchange element 10 is blown out toward the ceiling side by the guide grill 17, which not only prevents the blown outside air from hitting the user even if ventilation is performed during heating, but also allows the outside air to be blown out from below. Even when looking into the outlet 8, the guide grille 17 acts as a blind and blocks the line of sight, so the inside of the outside air outlet 8 cannot be seen, and the design is improved.

からの操作で実施することができる。For maintenance and inspection of the heat exchange element 10 and air filter 15, remove the intake grill 16 and open the indoor air intake port 9, and the air filter 15 on the indoor air inflow side will be exposed to the indoor air intake port 9. When the heat exchange element 10 is removed from the indoor air suction port 9, the indoor air inflow side of the heat exchange element 10 is exposed to the indoor air suction port 9. Therefore, maintenance work on the heat exchange element 10 can be performed using a suction cleaner or the like without removing the heat exchange element 10. Cleaning of the air inlet side of the other air filter 15 and heat exchange element 10 can also be done by opening the front end portion 14 of the shielding plate 4 by rotating it toward the indoor air intake port 9 side.
If the air filter 15 is exposed and removed from the indoor air suction port 9, the outside air inflow side of the heat exchange element 10 will be exposed to the indoor air suction port 9.
This can be done by operating from .

実施することができる。[Effects of the Invention] As is clear from the above description of the embodiments, the ceiling-mounted heat exchange ventilation device of the present invention incorporates functional parts such as a heat exchange element, an exhaust blower, and an intake blower in one main body outer casing. ,
Since the main body outer casing has the structure necessary for ventilation through intake and exhaust, the cover body that hides the main body outer casing can be divided into multiple parts to create a lightweight maintenance cover component that is easily attached and detached. In particular, the decorative cover that covers both sides of the main unit's outer casing is box-shaped with an open side on the main unit's outer casing and can be easily attached to and detached from the main unit's outer casing. The base, functional parts for damper operation, electronically controlled mounting boxes, etc. can be hidden behind decorative covers, making maintenance and electrical wiring work easier.
This can be easily carried out by simply removing the decorative cover and allowing visual confirmation.
