Description

本発明は、一体型空気調和機のファンケーシングに係わるものである。   The present invention relates to a fan casing of an integrated air conditioner.

従来の一体型空気調和機は、筒状に形成された外胴と、この外胴内に引出し可能に収納された内部ユニットとによって構成され、図６に示すように、内部ユニット１０１を構成するベース１０２に、このベース１０２上を室内側熱交換室１０３と室外側熱交換室１０４に仕切る仕切板１０５が固定され、室内側熱交換室１０３のベース１０２には、水受皿部１０６、ファンリング部１０７およびファンケーシング１０８が、発泡体１０９により一体的に形成されて設置された構成になっていた（例えば、特許文献１参照）。   The conventional integrated air conditioner includes an outer cylinder formed in a cylindrical shape and an internal unit that is housed in the outer cylinder so as to be able to be pulled out, and constitutes an internal unit 101 as shown in FIG. A partition plate 105 that divides the base 102 into an indoor heat exchange chamber 103 and an outdoor heat exchange chamber 104 is fixed to the base 102. The base 102 of the indoor heat exchange chamber 103 has a water tray portion 106, a fan ring, and the like. The part 107 and the fan casing 108 were configured to be integrally formed by the foam 109 (see, for example, Patent Document 1).

このものにおいて、水受皿部１０６、ファンリング部１０７およびファンケーシング１０８が発泡体１０９により一体成形されていることから、とくにファンリング部１０７やファンケーシング１０８などの形状または寸法の精度がよくないため、ファンリング部１０７を臨ませたシロッコファン（図示せず）による充分な送風性能が得られないという問題点があった。   In this case, since the water tray portion 106, the fan ring portion 107, and the fan casing 108 are integrally formed of the foam 109, the accuracy of the shape or dimensions of the fan ring portion 107, the fan casing 108, etc. is not particularly good. There is a problem that sufficient blowing performance cannot be obtained by a sirocco fan (not shown) with the fan ring portion 107 facing.

また、図７（Ａ）に示す要部斜視図または図７（Ｂ）に示す図７（Ａ）のａ−ａ断面図のように、樹脂成形した導風板１１０に樹脂成形した室内側ファンリング１１１を組み付ける構成の場合、これら導風板１１０および室内側ファンリング１１１の形状または寸法は精度がよくなるが、この室内側ファンリング１１１の内径よりも大きい外径のシロッコファン１１２をその回転軸の方向に移動させながら交換するには、導風板１１０と室内側ファンリング１１１とを本体から取り外してから交換作業をする必要があるが、交換作業の作業性が悪いという問題点があった（例えば、特許文献２参照）。   Further, as shown in FIG. 7A, a main part perspective view shown in FIG. 7A or an aa cross-sectional view in FIG. 7A shown in FIG. In the case of the structure in which the ring 111 is assembled, the shape or size of the air guide plate 110 and the indoor fan ring 111 is improved in accuracy, but the sirocco fan 112 having an outer diameter larger than the inner diameter of the indoor fan ring 111 is used as the rotation axis. In order to exchange while moving in the direction, it is necessary to perform the exchange work after removing the air guide plate 110 and the indoor fan ring 111 from the main body, but there is a problem that the workability of the exchange work is poor (For example, refer to Patent Document 2).

The fan casing 10b includes a semicircular fan ring opening 10b1 corresponding to the upper half of the indoor fan ring 9, and an upper joint 10b2.

ファンケーシング１０は、下部ファンケーシング１０ａに備えたファンリング用開口部の周縁１０ａ１と、上部ファンケーシング１０ｂに備えたファンリング用開口部の周縁１０ｂ１とで室内側ファンリング９を保持する保持部を構成し、保持部に隣接する内面側に、円環状に凹設された係合片受部１０ａ３，１０ｂ３を備え、保持部に隣接する外面側に、矩形状に凹設された複数の係合爪受部１０ａ４，１０ｂ４を備えている。   The fan casing 10 has a holding portion for holding the indoor fan ring 9 by a peripheral edge 10a1 of the fan ring opening provided in the lower fan casing 10a and a peripheral edge 10b1 of the fan ring opening provided in the upper fan casing 10b. A plurality of engaging recesses 10a3 and 10b3 that are annularly formed on the inner surface adjacent to the holding portion, and that are recessed in a rectangular shape on the outer surface adjacent to the holding portion. Claw receiving portions 10a4 and 10b4 are provided.

また、下部ファンケーシング１０ａに備えた下部接合部１０ａ２と、上部ファンケーシング１０ｂに備えた上部接合部１０ｂ２とは、図示はしないが、接合するのと同時に嵌合する凹凸状の嵌合部を備えることで、接合した部位の気密性を確保できるようにしている。   Moreover, although not shown in figure, the lower junction part 10a2 with which the lower fan casing 10a was equipped and the upper joint part 10b2 with which the upper fan casing 10b was equipped are equipped with the uneven | corrugated fitting part which fits simultaneously with joining. In this way, the airtightness of the joined parts can be secured.

室内側ファンリング９は、図４および図５に示すように、シロッコファン８に隣接させた先端９ｆの内径９ａがシロッコファン８の外径８ａよりも小径で形成されることで、シロッコファン８に効率よく導風するベルマウス部９ｅと、ファンケーシング１０に備えた保持部に係合するファンリング係合部９ｂとを備えている。   As shown in FIGS. 4 and 5, the indoor fan ring 9 is formed such that the inner diameter 9 a of the tip 9 f adjacent to the sirocco fan 8 is smaller than the outer diameter 8 a of the sirocco fan 8. A bell mouth portion 9e that efficiently guides air and a fan ring engaging portion 9b that engages with a holding portion provided in the fan casing 10 are provided.

ファンリング係合部９ｂは、ファンリング用開口部１０ｘの全周縁の内面側に備えた係合片受部１０ａ３，１０ｂ３に対応する円板状の係合片９ｃと、下部ファンケーシング１０ａのファンリング用開口部の周縁１０ａ１の外面側に備えた複数の係合爪受部１０ａ４，１０ａ４に対応する複数の係合爪９ｄと、上部ファンケーシング１０ｂのファンリング用開口部の周縁１０ｂ１の外面側に備えた複数の係合爪受部１０ｂ４，１０ｂ４に対応する複数の係合爪９ｄとを備えている。   The fan ring engaging portion 9b includes a disk-like engaging piece 9c corresponding to the engaging piece receiving portions 10a3 and 10b3 provided on the inner surface side of the entire peripheral edge of the fan ring opening 10x, and a fan of the lower fan casing 10a. A plurality of engagement claws 9d corresponding to the plurality of engagement claw receiving portions 10a4 and 10a4 provided on the outer surface side of the peripheral edge 10a1 of the ring opening, and the outer surface side of the peripheral edge 10b1 of the fan ring opening of the upper fan casing 10b And a plurality of engaging claws 9d corresponding to the plurality of engaging claw receiving portions 10b4 and 10b4.

これにより、室内側ファンリング９は、ファンケーシング１０に形成されたファンリング用開口部の周縁１０ａ１および１０ｂ１からなる保持部によりファンリング係合部９ｂが密着して係合されることになって、ファンケーシング１０に対し気密性を有して組み付けられるようになる。   As a result, the fan ring engaging portion 9b is closely engaged with the indoor side fan ring 9 by the holding portion including the peripheral edges 10a1 and 10b1 of the fan ring opening formed in the fan casing 10. The fan casing 10 is assembled with airtightness.

また、室内側ファンリング９が気密性を有して組み付けられた際、ファンケーシング１０の保持部に備えた係合片受部１０ａ３，１０ｂ３に室内側ファンリング９の係合片９ｃが係合し、複数の係合爪受部１０ａ４，１０ａ４と複数の係合爪受部１０ｂ４，１０ｂ４とに、複数の係合爪９ｄがそれぞれ係合する。   Further, when the indoor fan ring 9 is assembled with airtightness, the engaging piece 9c of the indoor fan ring 9 is engaged with the engaging piece receiving portions 10a3 and 10b3 provided in the holding portion of the fan casing 10. Then, the plurality of engaging claws 9d engage with the plurality of engaging claw receiving portions 10a4 and 10a4 and the plurality of engaging claw receiving portions 10b4 and 10b4, respectively.

なお、係合片受部１０ａ３，１０ｂ３は、図示はしないが、ファンリング用開口部１０ｘの全周縁の内面側に凹設するのではなく、ファンリング用開口部の周縁１０ａ１の外面側に備えた複数の係合爪受部１０ａ４，１０ａ４と同様に形成されてもよい。   Although not shown, the engaging piece receiving portions 10a3 and 10b3 are not provided on the inner surface side of the entire peripheral edge of the fan ring opening 10x, but are provided on the outer surface side of the peripheral edge 10a1 of the fan ring opening portion. The plurality of engaging claw receiving portions 10a4 and 10a4 may be formed similarly.

その場合には、上述した係合片９ｃは、円板状ではなく複数の係合爪受部１０ａ４，１０ａ４にそれぞれ係合する複数の係合爪９ｄと同様の形状に形成されることで、ファンケーシング１０の内面側と外面側とで複数の係合爪受部１０ａ４，１０ａ４に係合する。   In that case, the engagement piece 9c described above is not formed in a disc shape, but is formed in the same shape as the plurality of engagement claws 9d that respectively engage with the plurality of engagement claw receiving portions 10a4 and 10a4. The inner surface side and the outer surface side of the fan casing 10 are engaged with the plurality of engaging claw receiving portions 10a4 and 10a4.

複数の係合爪９ｄの側部が、ファンリング用開口部の周縁１０ａ１に備えた複数の係合爪受部１０ａ４，１０ａ４の側部で規制され、また、ファンリング用開口部の周縁１０ｂ１に備えた複数の係合爪受部１０ｂ４，１０ｂ４の側部で規制されることで、室内側ファンリング９は、回動しないよう位置決めされた状態で保持部に係合することになる。   The side portions of the plurality of engaging claws 9d are regulated by the side portions of the plurality of engaging claw receiving portions 10a4 and 10a4 provided on the peripheral edge 10a1 of the fan ring opening, and the peripheral edge 10b1 of the fan ring opening is provided. By being restricted by the side portions of the plurality of engaging claw receiving portions 10b4, 10b4 provided, the indoor fan ring 9 is engaged with the holding portion in a state of being positioned so as not to rotate.

回動しないように保持された室内側ファンリング９は、ベルマウス部９ｅの先端９ｆの内径９ａがシロッコファン８の外径８ａよりも小径に形成されている。これにより、ファンケーシング１０内への導風性を良好にして、シロッコファン８による送風性能を高めることができるようになる。   The indoor fan ring 9 held so as not to rotate is formed such that the inner diameter 9a of the tip 9f of the bell mouth portion 9e is smaller than the outer diameter 8a of the sirocco fan 8. As a result, the air guide into the fan casing 10 is improved and the air blowing performance by the sirocco fan 8 can be enhanced.

また、ファンリング用開口部の周縁１０ａ１および１０ｂ１からなる保持部（ファンリング用開口部１０ｘ）は、シロッコファン８の外径８ａよりも大径に形成されている。これにより、シロッコファン８を交換する際、シロッコファン８をファンモータ１９の駆動軸１９ａに沿って保持部の側に移動できるようになる。   In addition, the holding portion (fan ring opening 10x) composed of the peripheral edges 10a1 and 10b1 of the fan ring opening is formed to have a larger diameter than the outer diameter 8a of the sirocco fan 8. Thus, when the sirocco fan 8 is replaced, the sirocco fan 8 can be moved along the drive shaft 19 a of the fan motor 19 to the holding portion side.

そのため、上部ファンケーシング１０ｂが、下部ファンケーシング１０ａから取り外され、室内側ファンリング９が、下部ファンケーシング１０ａのファンリング用開口部の周縁１０ａ１から取り外されることで、シロッコファン８を保持部の側に移動させて容易に交換できるようになる。   Therefore, the upper fan casing 10b is removed from the lower fan casing 10a, and the indoor fan ring 9 is removed from the peripheral edge 10a1 of the fan ring opening of the lower fan casing 10a, so that the sirocco fan 8 is placed on the holding portion side. It can be easily exchanged by moving it.

以上説明したように、本発明の構成によれば、室内側ファンリング９が合成樹脂により形状および寸法が精度よく形成され、気密性を有してファンケーシング１０に保持されることで、室内側ファンリング９からファンケーシング１０内に導風して、シロッコファン８により室内側吹出口１ａから吹き出す送風性能を高めることができる。   As described above, according to the configuration of the present invention, the indoor fan ring 9 is accurately formed in shape and size from a synthetic resin and is held in the fan casing 10 with airtightness. It is possible to improve the air blowing performance of introducing air from the fan ring 9 into the fan casing 10 and blowing it out from the indoor air outlet 1a by the sirocco fan 8.

また、ファンケーシング１０が、下部ファンケーシング１０ａと上部ファンケーシング１０ｂとに分割形成され、室内側ファンリング９が着脱可能に保持されるので、上部ファンケーシング１０ｂおよび室内側ファンリング９を取り外すことで、シロッコファン８を、駆動軸１９ａの方向に移動可能にして容易に交換できるようにした一体型空気調和機となる。   Further, since the fan casing 10 is divided into a lower fan casing 10a and an upper fan casing 10b and the indoor fan ring 9 is detachably held, the upper fan casing 10b and the indoor fan ring 9 can be removed. Thus, the sirocco fan 8 is movable in the direction of the drive shaft 19a so that it can be easily replaced.
