Therefore, the effect of protecting the ceiling-embedded air conditioner from a body drop impact or the like at low cost is achieved.

以下、本発明の実施の形態について図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１Ａおよび図１Ｂは本発明の天井埋込型空気調和機の室内機部分の断面図である。本実施形態の天井埋込型空気調和機は、図３に示した従来型天井埋込型空気調和機例と同様、天井面に埋めこまれるケース本体１（要部のみ図示）を備え、ケース本体１の下面中央には吸い込み口２が設けられ、下面周部には吹き出し口（図示せず）が設けられている。ケース本体１内にはファンモータ４と、ファンモータ４の駆動軸により駆動される送風ファン５と、送風ファン５と吹き出し口３との間に配置された熱交換器６と、送風ファン５と吸い込み口２との間に設けられたエアガイダ７とが配置されている。ファンモータ４は、吸い込み口２と吹き出し口３とを結ぶ空気通路に設けられて吸い込み口２に対向し、上下方向の駆動軸を有する。   1A and 1B are cross-sectional views of an indoor unit portion of a ceiling-embedded air conditioner according to the present invention. The ceiling-embedded air conditioner of this embodiment includes a case main body 1 (only the main part is shown) embedded in the ceiling surface, as in the example of the conventional ceiling-embedded air conditioner shown in FIG. A suction port 2 is provided in the center of the lower surface of the main body 1, and a blow-out port (not shown) is provided in the periphery of the lower surface. In the case body 1, a fan motor 4, a blower fan 5 driven by a drive shaft of the fan motor 4, a heat exchanger 6 disposed between the blower fan 5 and the blowout port 3, An air guider 7 provided between the suction port 2 and the suction port 2 is disposed. The fan motor 4 is provided in an air passage that connects the suction port 2 and the blowout port 3, faces the suction port 2, and has a vertical drive shaft.

ファンモータ４は、ケース本体１の部分を構成する天井板１ａとファンモータ取付部１０との間に柔軟な合成ゴム等で成型されたゴムブッシング１１を介して、取付部材であるネジ９を用いて天井板１ａに取り付けられる。   The fan motor 4 uses a screw 9 as an attachment member through a rubber bushing 11 formed of a flexible synthetic rubber or the like between the ceiling plate 1a constituting the case body 1 and the fan motor attachment portion 10. And attached to the ceiling board 1a.

このように本実施形態の天井埋込型空気調和機の構成は、図３ならびに図４Ａないし図４Ｄに示した従来技術による天井埋込型空気調和機の構成と類似しているが、ゴムブッシング１１において相違点を有している。   As described above, the configuration of the ceiling-embedded air conditioner according to the present embodiment is similar to the configuration of the ceiling-embedded air conditioner according to the prior art shown in FIGS. 3 and 4A to 4D. 11 has a difference.

本実施形態のゴムブッシング１１（図１Ｄ参照。）は、その外縁部がファンモータ４取付部台座１０の外縁部よりも大きくなるよう形成されている。図１Ｃに示すように、本実施形態では、柔軟なゴムブッシング１１の外縁部は、取付部１０の外縁部よりも外側にある。よって、落下等による衝撃によってファンモータ４、送風ファン５等に揺動が生じた場合であっても、送風ファン５はゴムブッシング１１と衝突するため、ファンモータ４との衝突は回避され、ゴムブッシング１１の緩衝作用により、送風ファン５の受ける衝撃は低減される。   The rubber bushing 11 (see FIG. 1D) of the present embodiment is formed so that the outer edge portion thereof is larger than the outer edge portion of the fan motor 4 mounting portion base 10. As shown in FIG. 1C, in the present embodiment, the outer edge portion of the flexible rubber bushing 11 is outside the outer edge portion of the attachment portion 10. Therefore, even when the fan motor 4 and the blower fan 5 are swung due to an impact caused by dropping or the like, the blower fan 5 collides with the rubber bushing 11, so that the collision with the fan motor 4 is avoided, and the rubber Due to the buffering action of the bushing 11, the impact received by the blower fan 5 is reduced.

以上のようなゴムブッシング１１を用いることにより、図１Ａおよび図１Ｂに示す、送風ファン５とゴムブッシング１１との水平距離１１ａおよび距離１１ｂはそれぞれ、図３ならびに図４Ａないし図４Ｄに示した従来例における水平距離１０ａおよび距離１０ｂよりも短くなる。   By using the rubber bushing 11 as described above, the horizontal distance 11a and the distance 11b between the blower fan 5 and the rubber bushing 11 shown in FIGS. 1A and 1B are the same as those shown in FIGS. 3 and 4A to 4D, respectively. It becomes shorter than the horizontal distance 10a and the distance 10b in the example.

又、送風ファン５とエアガイダ７とが近接して配置される本実施形態にあっては、距離１１ｂを、送風ファン５とエアガイダ７との間の距離７ａと同等またはそれより小さく構成することが望ましい。なぜならば、距離１１ｂを距離７ａ以下にするすることにより、揺動による送風ファン５とエアガイダ７の衝突前に送風ファン５とゴムブッシング１１とが衝突するため、送風ファン５とエアガイダ７との衝突がゴムブッシング１１により間接的に回避されるからである。   In the present embodiment in which the blower fan 5 and the air guider 7 are disposed close to each other, the distance 11b may be configured to be equal to or smaller than the distance 7a between the blower fan 5 and the air guider 7. desirable. This is because when the distance 11b is set to be equal to or less than the distance 7a, the blower fan 5 and the rubber bushing 11 collide before the blower 5 and the air guider 7 collide with each other. This is because this is indirectly avoided by the rubber bushing 11.

さらに、水平距離１１ａを距離７ａと同等か、またはそれより小さくしてもよい。なぜならば、送風ファン５の形態は図示した形態に限定されず多様であり、また、振動衝撃による揺動形態もその衝撃の方向性によって多様であるため、水平距離１１ａを距離７ａ以下にすることで、より確実にエアガイダ７を衝突による損傷から防護できるようになるからである。   Further, the horizontal distance 11a may be equal to or smaller than the distance 7a. This is because the form of the blower fan 5 is not limited to the form shown in the figure, and there are various forms depending on the direction of the impact, so the horizontal distance 11a should be less than the distance 7a. This is because the air guider 7 can be more reliably protected from damage caused by the collision.

図２は、本実施の形態の柔軟なゴムブッシング１１の取付け形態を説明した図である。ゴムブッシング１１は、ファンモータ取付部台座１０に挿入するだけで容易に取り付けられる構成であり、ファンモータ取付部台座１０の周囲より外周が大きく台座１０の部分、および、外縁部を覆う形態を有する。ゴムブッシング１１がこのような構成を有するため、ケース本体１が落下等による衝撃を受けた場合であって、送風ファン５が上下左右に揺動しようとも、送風ファン５がファンモータ４の取付部台座１０と直接接触しない構成となっている。なお、ゴムブッシング１１の形状は、本図に示されている形態に限定されず、ファンモータ４や送風ファン５が揺動することで、送風ファン５が取付部１０と直接接触することが無いような形状であればよい。   FIG. 2 is a diagram for explaining a mounting form of the flexible rubber bushing 11 according to the present embodiment. The rubber bushing 11 is configured to be easily attached simply by being inserted into the fan motor attachment portion pedestal 10, and has a configuration in which the outer periphery is larger than the periphery of the fan motor attachment portion pedestal 10 and covers the portion of the pedestal 10 and the outer edge. . Since the rubber bushing 11 has such a configuration, even if the case body 1 receives an impact due to dropping or the like, even if the blower fan 5 swings up and down and left and right, the blower fan 5 is attached to the fan motor 4 mounting portion. It is the structure which does not contact the base 10 directly. The shape of the rubber bushing 11 is not limited to the form shown in this figure, and the blower fan 5 does not come into direct contact with the mounting portion 10 when the fan motor 4 or the blower fan 5 swings. Any shape can be used.

以上の構成により、本実施の形態は、図１Ａおよび図１Ｂに示すようにファン５とエアガイダ７との距離７ａも水平距離１１ａ、距離１１ｂより同等又は大きく構成されている。上記従来例のように、ケース本体１の落下、振動衝撃などによって天井板１ａに変形が生じたり、送風ファン５がエアガイダ７に衝突して生じる当該箇所の損傷を、本実施形態では回避している。   With the above configuration, in the present embodiment, as shown in FIGS. 1A and 1B, the distance 7a between the fan 5 and the air guider 7 is also equal to or greater than the horizontal distance 11a and the distance 11b. In this embodiment, as in the above-described conventional example, deformation of the ceiling plate 1a due to the drop of the case body 1, vibration shock, or the like, or damage to the portion caused by the blower fan 5 colliding with the air guider 7 is avoided. Yes.

なお、本実施形態においては、天井埋込型空気調和機について説明したが、本発明の思想は他の形式の空気調和機についても適用できることは言うまでもない。   In this embodiment, the ceiling-embedded air conditioner has been described, but it goes without saying that the idea of the present invention can be applied to other types of air conditioners.

本発明は、ファンモータ取付用の緩衝部材によって送風ファン、エアガイダ等、揺動により衝突するおそれのある箇所をより確実に保護し、当該箇所における損傷を無くするという効果を有し、例えば、天井埋込型空気調和機に有用である。   The present invention has an effect of more reliably protecting a portion where there is a possibility of collision due to swinging, such as a blower fan, an air guider, etc. by a buffer member for mounting a fan motor, and eliminating the damage at the portion, for example, a ceiling Useful for embedded air conditioners.
