As shown in Figure 6, be provided with and the relief opening 16 binding mouth 43 of same shape roughly in relief opening 16 1 sides of channel connector 4.Coincide owing to linking the position of mouth 43 with the relief opening 16 that is provided with for the air-supply function of keeping gas fan 8, so, it seems in the position of being partial to the left side from linking mouthful 43 1 sides.The side face that the left side of the relief opening of seeing in the side face of the formation of channel connector 4 and relief opening 16 bottoms and from relief opening 16 1 sides 16 contacts is equipped with and is used to prevent and the joining portion sealing gasket 18 that leak, that form the L word shape of main body 2.In addition, the binding mouth 43 1 on channel connector 4 tops is side-prominent, this protuberance 41a cover main body 2 above.
As shown in Figure 1, wind pressure type baffle plate 46 is installed in channel connector 4, it opens wide when exhaust, when not exhaust automatically or with lockings such as elastic force.
Next the combining mechanism of main body 2 with channel connector 4 described.Combining mechanism is made of the 1st combining mechanism 50 and the 2nd combining mechanism 60.
The 1st combining mechanism 50 as Fig. 2～shown in Figure 6, is meant the side that is arranged on relief opening 16 bottoms that form main body 2 and at the combining mechanism that forms on the binding mouth 43 of channel connector 4 on the following side.The 1st combining mechanism 50 in the present embodiment is described.In channel connector 4 one sides, Tu Chu chimeric pawl 51 is formed at 2 places downwards.In addition, in main body 2 one sides, embedding hole 52 corresponding chimeric pawls 51 that can chimeric described chimeric pawl 51 are formed at 2 places.In addition, as shown in Figure 7, the front end of described chimeric pawl 51 forms the conical surface 53, and forward end, its that face relative with the side of channel connector 4 are more to main body 2 lopsidedness more.By the formation of this conical surface 53, the 1st combining mechanism 50 in conjunction with the time chimeric pawl 51 be easier to enter in the embedding hole.In addition, by the formation of this conical surface 53, chimeric pawl 51 is chimeric with embedding hole 52, and channel connector 4 and main body 2 further mutually.
In addition, because described sealing gasket 18 is installed in channel connector 4 one sides upward like that, so, as Fig. 8 and shown in Figure 9, making the chimeric occasion of chimeric pawl 51 and embedding hole 52, sealing gasket 18 is in the state that keeps almost parallel with respect to the side of main body 2.This result, chimeric pawl 51 contact seal pads 18 and sealing gasket 18 is sustained damage.
Secondly, the 2nd combining mechanism 60 is meant the tabular protuberance 17 that forms with respect to 16 1 sides of relief opening in main body 2, is inserted in the structure of the insertion part 61 of channel connector 4 one sides formation from the top.In addition, as Fig. 2, Fig. 4, Fig. 5 and shown in Figure 6, insertion part 61 is formed at respectively up and down by the both sides in binding mouth 43 1 side face (that is the side face of relief opening 16 1 sides) of channel connector 4 that the following insertion part 62 and the last insertion part 63 in 2 places constitute.
As shown in Figure 5, the part of the biside plate of following insertion part 62 its channel connectors 4 bends to " コ " word shape and forms to main body 2 one sides.That is, following insertion part 62 its horizontal section shapes form " コ " word shapes.In addition, as shown in figure 10, following insertion part 62 becomes the tilted shape of opening wide to main body 2 one sides when the section of Vertical direction is seen, this incline section forms guide portion 64.Guide portion 64 following insertion part 62 with respect to tabular protuberance 17 from above the occasion inserted, to tabular protuberance 17 guidings insertion parts 62 down.
Last insertion part 63 is the same with described following insertion part 62, and the biside plate part of its channel connector 4 bends to " コ " word shape to main body 2 one sides and forms.That is, last insertion part 63 its horizontal section shapes form " コ " word shapes.In addition, last insertion part 63 is different with following insertion part 62, and as shown in figure 10, the section shape of its Vertical direction forms vertical configuration.
In addition, as Fig. 4 and shown in Figure 10 since will be described such following insertion part 62 and on insertion part 63 with mould-forming, so, need be formed for the hole 65,66 of the demoulding.On the other hand, owing to link mouthfuls 43, it seems the deflection left side from the side that links mouthful 43 1 sides, so the side in binding mouth 43 left sides becomes narrow as described.This result might leak out water of condensation by being formed at when exhaust is come in the hole 65,66 that links mouthful 43 left sides.Therefore, in the present embodiment, sealing gasket 18 is made L word shape,, prevent seepage from the water of condensation that is present in the hole 65,66 that links mouthful 43 left sides so that make sealing gasket 18 be present in the left lateral sides that links mouth 43 upward like that.
In addition, the right side side face of the binding mouth of seeing from the side that links mouthful 43 1 sides 43, as in Fig. 6, seeing, except become broad, to the size in hole 65,66 become big, owing to linking formation recess 67 between mouth 43 and the hole 65,66, so, do not worry that water of condensation leaks out from the hole 65,66 that links mouthful 43 right sides.
As shown in Figure 1, though the bottom surface of channel connector 4 constitutes the bottom surface of exhaust passageway 42, but, near relief opening 16 1 side ends, has the plane of inclination 48 that (promptly opposite with a relief opening side) tilts from relief opening 16 1 side ends towards channel connector 4 one sides downwards, owing to have this plane of inclination, the water of condensation of condensing in main body 2 one sides can not be trapped in the connecting part of main body 2 and channel connector 4, and successfully in the flow channel joint 4.Here, by making sealing gasket 18 and fan guard 13, also having the height relationships of sealing gasket 18 and plane of inclination 48 to become as shown in Figure 7: the upper end of sealing gasket 18 is lower than fan guard 13, and, the peak of plane of inclination 48 is lower than the upper end of sealing gasket 18, discharges to passage 41 1 sides thereby water of condensation is easier.
In the air exchanging fan for passage 1 of described this structure, channel connector 4 combines with main body 2 as following.
