くなるなどの問題があり実用的でなかった。Problems to be Solved by the Invention Among the seal structures of the heat exchange type fan 6 used in such a conventional clothes dryer, in the case of the contact type, the felt material 7 is worn out over a long period of use and a gap is formed. As a result, the seal is incomplete and the performance is deteriorated, and the workability for attaching the felt material 7 to the outer peripheral portion of the heat exchange type fan 6 and attaching the sliding member 11 is poor. In the non-contact type structure, there is a gap 13, and the pressure difference between the circulating air and the cooling air reduces the dehumidification performance due to air replacement.To reduce air replacement, the number of circumferential ribs 12 is reduced. More gaps
13 needs to be lengthened, so that the heat exchange fan 6
However, if the outer diameter is large, or if the outer diameter is kept as it is, there is a problem that the effective area for heat exchange of the heat exchange type fan 6 is reduced, and this is not practical.

In this embodiment, the same components as those shown in the above-described conventional example are denoted by the same reference numerals, and the description thereof will be omitted. The characteristic structure of the present embodiment lies in the seal structure of the heat exchange fan unit. That is, circumferential ribs 12 having a plurality of concentric teeth are provided on the outer periphery of the heat exchange fan 6 and the opening edge of the partition plate 11 of the fan case 8 containing the heat exchange fan 6, respectively. The comb teeth of the circumferential rib 12 are engaged with each other with a gap therebetween.

い。With the above configuration, the provision of the annular plate 14 in the fan case 8 delays the gap between the comb teeth of the two circumferential ribs 12 by extending to the gap 15. Therefore, the performance can be secured by reducing the replacement of the circulating air and the cooling air. Also,
Since the annular plate 14 is an elastic body, if the fan case cover 17 is removed in a state where the annular plate 14 is fixed to the heat exchange type fan, the heat exchange type fan 6 and the fan case 8 can be assembled. In the embodiment, the annular plate 14 is attached by the screw 18, but the annular plate 14 and the heat exchange type fan 6 may be formed integrally.

性をよくする効果を有する。As is clear from the above description of the embodiment, the present invention includes a heat exchange type fan for separating a circulation air path and a cooling air path, and a fan case incorporating the heat exchange type fan. Around the opening edge of the partition plate and the outer peripheral portion of the heat exchange type fan are provided circumferential ribs having a plurality of comb teeth concentrically, and the comb teeth of both circumferential ribs are engaged with each other with a gap therebetween. An annular plate of an elastic body is arranged on the circulating air path side of the circumferential rib of the heat exchange type fan,
And, in a state where the heat exchange type fan is mounted on the fan case, the annular plate covers the outlet on the circulating air path side of the gap formed by the comb teeth of the two circumferential ribs. In the contact seal type, the gap is extended and the replacement of the circulating air and the cooling air is reduced, and the dehumidifying performance can be secured. In addition, assembling can be performed without removing the annular plate, which has the effect of improving workability.
