１，１２を切換可能に閉鎖する。 Conventionally, there have been ventilators of this type as shown in FIGS. 1 to 3. In the figure, 1 is a casing body having an air supply passage and an exhaust passage, and an air supply fan 2, an exhaust fan 3, a motor 4, etc. are built in the casing body. 5 is a heat exchanger attached to the front of the casing body 1; 6 is a damper that rotates around a shaft 6a to switch the air supply air path; 7 is a decoration that covers the heat exchanger 5 and the damper 6. The grill is fixed to the casing body 1 with screws 8. This decorative grille 7 has an intake port at the front and the top, and an exhaust port at the front. Reference numeral 11 denotes a first communication portion that communicates the upper intake port of the grille 7 with the exhaust passage of the casing body 1;
Reference numeral 2 denotes a second communication portion that communicates between the upper intake port of the grill 7 and the heat exchanger 5, and the damper 6 refers to the communication portion 1.
1 and 12 are switchably closed.

とその当接部分が平面同志では給気が洩れて換気
装置としては好ましくなかつた。 In the above configuration, the air supply fan 2 and the exhaust fan 3 are rotated by the drive of the motor 4, and the air supply passes from the back to the lower part of the casing body 1 as shown by the dotted line, and is heat exchanged with the exhaust air in the heat exchanger 5. do. Thereafter, since the damper 6 is in the open state and in contact with the edge 1a, the intake air is discharged from the intake ports in front and above the grille 7. On the other hand, the exhaust gas enters the casing body 1 via the heat exchanger 5 as shown by the two-dot chain line, and enters the lower part of the casing body 1 (separated from the intake side).
and is ejected from the back. Furthermore, when the damper 6 closes the upper side of the grill 7 as shown by the two-dot chain line, the intake air is discharged only from the front of the grill 7, and the exhaust air is taken in from the heat exchanger 5 and the grill 7. It is also inhaled from the upper air intake port.
However, since the damper 6 is in contact with the edge 1a of the casing body 1 when it is open, for example, the damper 6 may be warped or distorted as shown in FIG. If there is a gap between them, a part of the supply air may be sucked in by the exhaust flow and leak. Although this was a sufficient characteristic for the blower alone, the characteristic was not sufficient when viewed as a ventilation system. Because of this, damper 6
If the abutting parts were flat, supply air would leak, which was not desirable as a ventilation system.

ている。 This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and includes a recess and a projection that engage relatively with the damper and the edge of the casing body that the damper contacts. The purpose is to provide a ventilation system that prevents leakage of supply air.

形成してある。 An embodiment of this invention will be described below with reference to the drawings. In Figs. 5 to 8, reference numeral 1 denotes a casing body in which an air supply fan 2, an exhaust fan 3, a motor 4, etc. are built. 5 is a heat exchanger attached to the front of the casing body 1; 6;
7 is a damper that rotates about a shaft 6a as a fulcrum to switch the air supply air path; 7 is a decorative grill that covers the heat exchanger 5 and the damper 6, and is fixed to the casing body 1 with screws 8. A recess 9 is formed in the damper 6, as shown in an enlarged view in FIG. 8, and a protrusion 10 that engages with the recess 9 is formed on the edge 1a of the casing body 1 that the damper 6 comes into contact with. There is.

凸部とを設けてあればよい。 With this configuration, when the damper 6 is opened, the recess 9 provided in the damper 6 is in contact with the casing body 1.
Since the damper 6 and the edge 1a are engaged with the convex portion 10 of the edge 1a, the damper 6 and the edge 1a are sealed, thereby completely preventing the supply air from being sucked into the exhaust flow. In addition, in the embodiment, a recess is provided in the damper 6, and the edge 1
Although the example in which the convex portion 10 is provided in the damper 6 has been described, it is sufficient to provide a concave portion and a convex portion that engage relatively with the damper 6 and the edge portion 1a.

ができる。 As described above, according to this invention, by providing the damper and the casing body with which the damper comes into contact with a recess and a projection that relatively engage with each other,
Since the supply air is sucked into the exhaust flow and does not leak, the characteristics of the ventilation system can be fully demonstrated. Further, if the damper is provided with a concave portion or a convex portion, the damper itself is reinforced and has the effect of preventing warping and distortion. Furthermore, by switching the damper, the amount of intake air and exhaust air can be adjusted, allowing optimal ventilation.
