Description

筒状断熱部材および冷凍サイクル装置Cylindrical heat insulating member and refrigeration cycle apparatus
　本発明は、折り返し点を有する冷媒配管の湾曲部を覆う筒状断熱部材および冷凍サイクル装置に関する。 The present invention relates to a cylindrical heat insulating member and a refrigeration cycle apparatus that cover a curved portion of a refrigerant pipe having a turning point.
　従来、冷媒配管の湾曲部を覆う筒状断熱部材が知られている（たとえば、特許文献１、２参照）。特許文献１に記載された筒状断熱部材は、配管の加熱成型前に配管に取り付けていた。特許文献２に記載された筒状断熱材は、配管に対して熱融着によって取り付けられていた。 Conventionally, a cylindrical heat insulating member that covers a curved portion of a refrigerant pipe is known (for example, see Patent Documents 1 and 2). The cylindrical heat insulating member described in Patent Document 1 is attached to the pipe before the pipe is heat-molded. The cylindrical heat insulating material described in Patent Document 2 is attached to the pipe by heat fusion.

　特許文献１の筒状断熱部材は、加熱成型前に取り付けられたために、加熱成型時もしくは配管溶接時に熱によって溶解する場合がある。特許文献２の筒状断熱材は、取付が熱融着によるので、作業効率が悪かった。 Since the cylindrical heat insulating member of Patent Document 1 is attached before heat molding, it may be melted by heat during heat molding or pipe welding. Since the tubular heat insulating material of Patent Document 2 is attached by heat fusion, the work efficiency is poor.
　そのため、筒状断熱部材が熱による影響を受けない冷媒配管の溶接後に取り付けられることが望まれた。また、熱融着などの手間が必要無く、作業効率が良く取り付けられることが望まれた。 Therefore, it was desired that the cylindrical heat insulating member be attached after welding of the refrigerant pipe that is not affected by heat. In addition, it is desired that the work can be attached with good work efficiency without the need for heat fusion or the like.
　一方、筒状断熱部材は、冷媒配管を覆う。このため、筒状断熱部材には、冷媒配管の表面で生じる結露水などの液体が流れ込む。このような結露水などの液体が筒状断熱部材の表面から散らばって流れ落ちないことが望まれた。 Meanwhile, the cylindrical heat insulating member covers the refrigerant pipe. For this reason, liquids, such as the dew condensation water which arises on the surface of refrigerant | coolant piping, flow into a cylindrical heat insulation member. It has been desired that liquid such as condensed water is not scattered from the surface of the tubular heat insulating member.
　本発明は、上記課題を解決するためのものであり、冷媒配管の接続後に作業効率が良く容易に取り付けられるとともに、結露水などの液体が表面から散らばって流れ落ちない筒状断熱部材および冷凍サイクル装置を提供することを目的とする。 The present invention is for solving the above-mentioned problems, and is a cylindrical heat insulating member and a refrigeration cycle apparatus that are easily attached with good working efficiency after connection of refrigerant pipes, and in which liquid such as condensed water is scattered from the surface and does not flow down. The purpose is to provide.
　本発明に係る筒状断熱部材は、最下部に折り返し点を有する冷媒配管の湾曲部を覆う筒状断熱部材であって、上半体にて、上向きに開口する両端の上端部同士がそれぞれ繋がるように形成される切れ目と、前記切れ目の一部を含む前記折り返し点の上方投影領域に接続され、下方に液体を案内する案内流路と、を備えるものである。 The cylindrical heat insulating member according to the present invention is a cylindrical heat insulating member that covers the curved portion of the refrigerant pipe having the turning point at the lowermost part, and upper ends of both ends that open upward are connected to each other in the upper half. And a guide channel that is connected to the upper projection region of the folding point including a part of the cut and guides the liquid downward.
　本発明に係る冷凍サイクル装置は、上記の筒状断熱部材を前記冷媒配管に装着するものである。 The refrigeration cycle apparatus according to the present invention is a device in which the cylindrical heat insulating member is attached to the refrigerant pipe.
　本発明に係る筒状断熱部材および冷凍サイクル装置によれば、上半体にて、上向きに開口する両端の上端部同士がそれぞれ繋がるように形成される切れ目と、切れ目の一部を含む折り返し点の上方投影領域に接続され、下方に液体を案内する案内流路と、を備える。これにより、筒状断熱部材は、切れ目を開いて冷媒配管に容易に取り付けられる。また、筒状断熱部材は、取付後に内部に浸入する結露水などの液体を切れ目から案内流路に流して下方に案内できる。したがって、筒状断熱部材が冷媒配管の接続後に作業効率が良く容易に取り付けられるとともに、結露水などの液体が表面から散らばって流れ落ちない。 According to the cylindrical heat insulating member and the refrigeration cycle apparatus according to the present invention, the upper half of the upper end of both ends that open upward are connected to each other, and the turning point including a part of the cut And a guide channel that guides the liquid downward. Thereby, a cylindrical heat insulation member opens a cut | interruption and is easily attached to refrigerant | coolant piping. In addition, the tubular heat insulating member can guide the liquid downwardly by flowing a liquid such as dew condensation water that enters the interior after installation from the cut into the guide channel. Therefore, the cylindrical heat insulating member is easily attached with good work efficiency after the refrigerant pipe is connected, and liquid such as condensed water is scattered from the surface and does not flow down.

＜筒状断熱部材１０の周辺構成＞

FIG. 4 is a perspective view showing a peripheral portion of the cylindrical heat insulating member 10 attached to the refrigerant pipe 9 in the machine room 20b according to Embodiment 1 of the present invention. As shown in FIG. 4, a refrigerant pipe 9 is installed in the machine room 20b. A tubular heat insulating member 10 is attached to the refrigerant pipe 9. That is, the place where the tubular heat insulating member 10 is attached to the refrigerant pipe 9 is inside the outdoor unit 100 of the air conditioner 200.
　筒状断熱部材１０は、最下部に折り返し点９ａを有するＵ字状の湾曲部を有する冷媒配管９に取り付けられる。筒状断熱部材１０は、Ｕ字状の冷媒配管９を覆うＵ字状である。筒状断熱部材１０の両端の上端部１０ａ、１０ｂは、それぞれが同じ高さまで冷媒配管９を覆う。 The cylindrical heat insulating member 10 is attached to the refrigerant pipe 9 having a U-shaped curved portion having a turning point 9a at the lowermost part. The tubular heat insulating member 10 has a U shape that covers the U-shaped refrigerant pipe 9. The upper end portions 10a and 10b at both ends of the tubular heat insulating member 10 cover the refrigerant pipe 9 to the same height.
　なお、筒状断熱部材１０は、Ｕ字状でなくても良い。筒状断熱部材１０は、たとえばＪ字状などのように湾曲部を有する形状であっても良い。また、筒状断熱部材１０は、円筒状を例示している。しかし、筒状断熱部材１０は、四角筒状あるいは六角筒状などの多角筒状でも良い。 In addition, the cylindrical heat insulation member 10 does not need to be U-shaped. The tubular heat insulating member 10 may have a curved portion such as a J shape. Moreover, the cylindrical heat insulation member 10 has illustrated cylindrical shape. However, the cylindrical heat insulating member 10 may be a polygonal cylinder such as a square cylinder or a hexagonal cylinder.
＜筒状断熱部材１０の構成＞
　図５は、本発明の実施の形態１に係る筒状断熱部材１０を示す斜視図である。図５に示すように、筒状断熱部材１０は、Ｕ字状である。筒状断熱部材１０は、ゴムホースである。筒状断熱部材１０は、上半体１０ｃにて、上向きに開口する両端の上端部１０ａ、１０ｂ同士がそれぞれ繋がるように形成された切れ目１１を備える。より詳しくは、切れ目１１は、筒状断熱部材１０の上半体１０ｃにおけるＵ字状の冷媒配管９の湾曲部の内側に筒状断熱部材１０のＵ字状に沿って形成される。切れ目１１は、延出方向に対する直交方向での間隔を一定に形成される。ここで、筒状断熱部材１０の上半体１０ｃとは、円筒状の筒状断熱部材１０の延びる方向に対する断面にて上半分の円弧部分を示す。 <Configuration of cylindrical heat insulating member 10>
FIG. 5 is a perspective view showing the cylindrical heat insulating member 10 according to Embodiment 1 of the present invention. As shown in FIG. 5, the tubular heat insulating member 10 is U-shaped. The tubular heat insulating member 10 is a rubber hose. The tubular heat insulating member 10 includes a cut 11 formed so that upper ends 10a and 10b at both ends that open upward are connected to each other in the upper half 10c. More specifically, the cut 11 is formed along the U-shape of the tubular heat insulating member 10 inside the curved portion of the U-shaped refrigerant pipe 9 in the upper half 10 c of the tubular heat insulating member 10. The cut line 11 is formed with a constant interval in the direction orthogonal to the extending direction. Here, the upper half 10c of the tubular heat insulating member 10 indicates an upper half arc portion in a cross section with respect to the extending direction of the cylindrical heat insulating member 10.
　筒状断熱部材１０は、表面を凹ませた溝に形成される案内流路１２を備える。案内流路１２は、切れ目１１の一部を含む冷媒配管９の折り返し点９ａの上方投影領域のうち直上位置に始点１１ａを有する。案内流路１２は、切れ目１１における最下部の位置の始点１１ａに接続され、下方に結露水などの液体を案内する。案内流路１２は、筒状断熱部材１０の周方向に形成される。案内流路１２は、切れ目１１から筒状断熱部材１０の片方側に下方に向けて１つだけ形成される。 The cylindrical heat insulating member 10 includes a guide channel 12 formed in a groove having a recessed surface. The guide channel 12 has a starting point 11a at a position directly above the upper projection region of the turning point 9a of the refrigerant pipe 9 including a part of the cut 11. The guide channel 12 is connected to the starting point 11a at the lowest position in the cut line 11, and guides a liquid such as condensed water downward. The guide channel 12 is formed in the circumferential direction of the tubular heat insulating member 10. Only one guide channel 12 is formed downward from the cut 11 to one side of the tubular heat insulating member 10.
　図６は、本発明の実施の形態１に係る筒状断熱部材１０を示す側面平面図である。図７は、本発明の実施の形態１に係る筒状断熱部材１０を示す図６のＡ－Ａ断面図である。図７に示すように、切れ目１１は、筒状断熱部材１０の中心軸方向に直交する断面が筒状断熱部材１０の半径方向の内側程狭い幅のＶ字状に形成される。また、案内流路１２は、始点１１ａから水平方向の最外径位置１２ａまで形成される。なお、案内流路１２は、始点１１ａから水平方向の最外径位置１２ａより下方まで形成されても良い。また、案内流路１２の溝幅は、一定に形成される。 FIG. 6 is a side plan view showing the tubular heat insulating member 10 according to Embodiment 1 of the present invention. FIG. 7 is a cross-sectional view taken along line AA of FIG. 6 showing the tubular heat insulating member 10 according to Embodiment 1 of the present invention. As shown in FIG. 7, the cut line 11 is formed in a V-shape in which the cross section perpendicular to the central axis direction of the tubular heat insulating member 10 is narrower toward the inner side in the radial direction of the tubular heat insulating member 10. The guide channel 12 is formed from the starting point 11a to the outermost diameter position 12a in the horizontal direction. In addition, the guide flow path 12 may be formed from the starting point 11a to a position below the outermost diameter position 12a in the horizontal direction. Further, the groove width of the guide channel 12 is formed constant.
＜筒状断熱部材１０の作用＞
　筒状断熱部材１０は、切れ目１１をＶ字状に形成されることにより、冷媒配管９に対して切れ目１１を押し込むだけで容易に取り付けられる。また、切れ目１１の外周側の間隔が広いので、筒状断熱部材１０の取付時には、冷媒配管９に押し込んで取り付け易い。また、切れ目１１の内周側の間隔が狭いので、筒状断熱部材１０の取付後には、筒状断熱部材１０が冷媒配管９から外れ難い。このように、冷媒配管９の溶接が完了した組み付け後に、熱溶着に代表される接着剤による接着が必要なく、筒状断熱部材１０が冷媒配管９に取り付けられる。また、切れ目１１の間隔を一定に設定することにより、冷媒配管９のＵ字状の湾曲部の全体にわたって筒状断熱部材１０の密着度が高くできる。これにより、筒状断熱部材１０の取付後に、筒状断熱部材１０が冷媒配管９から外れ難い。 <Operation of the tubular heat insulating member 10>
The tubular heat insulating member 10 is easily attached by simply pushing the cut 11 into the refrigerant pipe 9 by forming the cut 11 in a V shape. Moreover, since the space | interval of the outer peripheral side of the cut | interruption 11 is wide, at the time of attachment of the cylindrical heat insulation member 10, it pushes into the refrigerant | coolant piping 9 and is easy to attach. Moreover, since the space | interval of the inner peripheral side of the cut | interruption 11 is narrow, after the cylindrical heat insulation member 10 is attached, the cylindrical heat insulation member 10 is hard to remove | deviate from the refrigerant | coolant piping 9. FIG. As described above, after the assembly of the refrigerant pipe 9 is completed, the tubular heat insulating member 10 is attached to the refrigerant pipe 9 without the need for bonding with an adhesive typified by heat welding. Further, by setting the interval between the cut lines 11 constant, the degree of adhesion of the tubular heat insulating member 10 can be increased over the entire U-shaped curved portion of the refrigerant pipe 9. Thereby, after the tubular heat insulating member 10 is attached, the tubular heat insulating member 10 is not easily detached from the refrigerant pipe 9.
　このように、筒状断熱部材１０は、冷媒配管９の組上げ後に取り付けられるので、筒状断熱部材１０が配管溶接によって溶けることがない。また、切れ目１１が形成されるので、筒状断熱部材１０を冷媒配管９に接着剤を用いず容易に取り付けられる。 Thus, since the cylindrical heat insulating member 10 is attached after the refrigerant pipe 9 is assembled, the cylindrical heat insulating member 10 is not melted by pipe welding. Moreover, since the cut line 11 is formed, the cylindrical heat insulating member 10 can be easily attached to the refrigerant pipe 9 without using an adhesive.
　また、筒状断熱部材１０の周方向に案内流路１２を設けるので、筒状断熱部材１０の内部に流れ込む結露水などの液体が筒状断熱部材１０の表面にて流れる方向が制御できる。案内流路１２が溝であることにより、筒状断熱部材１０のＵ字状の頂点部分である始点１１ａが外側にめくれ難くなり、筒状断熱部材１０が冷媒配管９に密着して外れ難い。案内流路１２が筒状断熱部材１０の周方向の片方に１つだけに設けられることにより、筒状断熱部材１０の片方側だけに結露水などの液体が排出できる。案内流路１２の設けられなかった側には、結露水などの液体が流れ落ちない。これにより、案内流路１２の設けられなかった側に存在する部品配置領域に結露水などの液体がふりかからない。これにより、冷媒配管９の下部に設けるドレンパンなどが小型化できる。 Further, since the guide flow path 12 is provided in the circumferential direction of the cylindrical heat insulating member 10, the direction in which liquid such as condensed water flowing into the cylindrical heat insulating member 10 flows on the surface of the cylindrical heat insulating member 10 can be controlled. Since the guide channel 12 is a groove, the starting point 11a which is the U-shaped apex portion of the tubular heat insulating member 10 is difficult to turn outward, and the tubular heat insulating member 10 is in close contact with the refrigerant pipe 9 and is difficult to come off. By providing only one guide channel 12 on one side in the circumferential direction of the cylindrical heat insulating member 10, liquid such as condensed water can be discharged only on one side of the cylindrical heat insulating member 10. A liquid such as condensed water does not flow down on the side where the guide channel 12 is not provided. Thereby, liquids, such as condensed water, do not splash on the components arrangement | positioning area | region which exists in the side in which the guide flow path 12 was not provided. Thereby, the drain pan etc. which are provided in the lower part of the refrigerant | coolant piping 9 can be reduced in size.
＜切れ目１１の変形例＞
　なお、切れ目１１は、筒状断熱部材１０におけるＵ字状の頂点近傍の間隔を筒状断熱部材１０のＵ字状の両上端部１０ａ、１０ｂ側の間隔よりも大きくしても良い。これによれば、筒状断熱部材１０におけるＵ字状の頂点近傍の密着度が低下するものの、Ｕ字状の頂点近傍における筒状断熱部材１０の押し込み取付けをより容易に行える。 <Modification of cut 11>
In the cut line 11, the interval between the U-shaped apexes of the tubular heat insulating member 10 may be larger than the distance between the U-shaped upper ends 10 a and 10 b of the tubular heat insulating member 10. According to this, although the degree of adhesion in the vicinity of the U-shaped apex of the tubular heat insulating member 10 is lowered, the push-in attachment of the cylindrical heat insulating member 10 in the vicinity of the U-shaped apex can be performed more easily.
　また、切れ目１１は、筒状断熱部材１０の上半体１０ｃにて、両側の上向きに開口する上端部１０ａ、１０ｂ同士がそれぞれ繋がるように形成されれば良い。このため、切れ目１１は、筒状断熱部材１０の上半体１０ｃにて冷媒配管９の湾曲部の内側部分以外に形成されたり、筒状断熱部材１０における冷媒配管９の湾曲部の内側となる仮想線に対して斜め方向に形成されたりしても良い。また、切れ目１１は、直線状の他に、曲線状あるいは蛇行線状などに形成されても良い。 Moreover, the cut | interruption 11 should just be formed so that the upper end parts 10a and 10b which open upwards on both sides may be connected in the upper half body 10c of the cylindrical heat insulation member 10, respectively. For this reason, the cut line 11 is formed in the upper half body 10c of the tubular heat insulating member 10 other than the inner portion of the curved portion of the refrigerant pipe 9, or inside the curved portion of the refrigerant pipe 9 in the tubular heat insulating member 10. It may be formed in an oblique direction with respect to the virtual line. Further, the cut line 11 may be formed in a curved shape or a meandering line shape in addition to the linear shape.
＜案内流路１２の変形例＞
　なお、案内流路１２は、溝ではなく、切れ目でも良い。案内流路１２は、切れ目である場合には、結露水などの液体の排出効果を得たまま、筒状断熱部材１０のＵ字状の頂点である直上位置の始点１１ａが柔軟に変形して冷媒配管９に嵌め込み易い。なお、案内流路１２は、切れ目１１に接する部分の幅を切れ目１１から遠い部分の溝幅よりも大きく形成しても良い。これによれば、結露水などの液体の量が多いときでも、筒状断熱部材１０のＵ字状の頂点である始点１１ａ近傍に流れ込んできた結露水などの液体が漏らさずに一点に集めて排出できる。 <Modification of guide channel 12>
Note that the guide channel 12 may be not a groove but a cut line. When the guide channel 12 is cut, the starting point 11a at the position directly above the U-shaped apex of the tubular heat insulating member 10 is flexibly deformed while obtaining the effect of discharging liquid such as condensed water. Easy to fit into the refrigerant pipe 9. In addition, you may form the guide flow path 12 so that the width | variety of the part which touches the cut | interruption 11 is larger than the groove width of a part far from the cut | interruption 11. FIG. According to this, even when the amount of liquid such as condensed water is large, the liquid such as condensed water that has flowed in the vicinity of the starting point 11a that is the U-shaped apex of the tubular heat insulating member 10 is collected at one point without leaking. Can be discharged.
　また、案内流路１２は、筒状断熱部材１０の装着後に結露水などの液体を案内するように後から作業者によって形成されても良い。また、案内流路１２は、複数形成されても良い。複数の案内流路１２は、切れ目１１から筒状断熱部材１０の両側にそれぞれ形成されても良い。複数の案内流路１２は、切れ目１１から筒状断熱部材１０の片方側にまとめて形成されても良い。 Further, the guide channel 12 may be formed later by an operator so as to guide a liquid such as condensed water after the tubular heat insulating member 10 is mounted. In addition, a plurality of guide channels 12 may be formed. The plurality of guide channels 12 may be formed on both sides of the tubular heat insulating member 10 from the cut line 11. The plurality of guide channels 12 may be formed collectively on one side of the tubular heat insulating member 10 from the cut 11.
＜実施の形態１の変形例１＞
　図８は、本発明の実施の形態１の変形例１に係る筒状断熱部材１０を示す斜視図である。図８に示すように、切れ目１１は、筒状断熱部材１０の折り返し点９ａの上方投影領域を大きな孔部１１ｂとして形成されても良い。そして、案内流路１２は、孔部１１ｂから冷媒配管９の折り返し点９ａの直上位置からずれた始点１１ａに繋がっていても良い。このように、案内流路１２の始点１１ａは、筒状断熱部材１０の折り返し点９ａの上方投影領域のうち直上位置だけに限られない。 <Modification 1 of Embodiment 1>
FIG. 8 is a perspective view showing a tubular heat insulating member 10 according to Modification 1 of Embodiment 1 of the present invention. As shown in FIG. 8, the cut line 11 may be formed with a large projected portion 11 b in the upper projection area of the turning point 9 a of the tubular heat insulating member 10. And the guide flow path 12 may be connected with the starting point 11a which shifted | deviated from the position directly above the folding | turning point 9a of the refrigerant | coolant piping 9 from the hole 11b. As described above, the starting point 11a of the guide channel 12 is not limited to the position directly above the upper projection area of the turning point 9a of the tubular heat insulating member 10.
＜実施の形態１の変形例２＞
　図９は、本発明の実施の形態１の変形例２に係る筒状断熱部材１０を示す斜視図である。図９に示すように、案内流路１２は、始点１１ａから水平方向の最外径位置１２ａ以上まで下方に形成されても良い。また、案内流路１２は、結露水などの液体を導きたい方向に曲がって形成されても良い。 <Modification 2 of Embodiment 1>
FIG. 9 is a perspective view showing a cylindrical heat insulating member 10 according to Modification 2 of Embodiment 1 of the present invention. As shown in FIG. 9, the guide channel 12 may be formed downward from the starting point 11a to the outermost radial position 12a in the horizontal direction. Further, the guide channel 12 may be formed by bending in a direction in which a liquid such as condensed water is to be guided.
＜実施の形態１の効果＞
　実施の形態１によれば、筒状断熱部材１０は、最下部に折り返し点９ａを有する冷媒配管９の湾曲部を覆う。筒状断熱部材１０は、上半体１０ｃにて、上向きに開口する両端の上端部１０ａ、１０ｂ同士がそれぞれ繋がるように形成される切れ目１１を備える。筒状断熱部材１０は、切れ目１１の一部を含む折り返し点９ａの上方投影領域に接続され、下方に液体を案内する案内流路１２を備える。 <Effect of Embodiment 1>
According to Embodiment 1, the cylindrical heat insulation member 10 covers the curved part of the refrigerant | coolant piping 9 which has the folding | turning point 9a in the lowest part. The tubular heat insulating member 10 includes a cut 11 formed in the upper half 10c so that upper ends 10a and 10b at both ends opened upward are connected to each other. The tubular heat insulating member 10 is connected to an upper projection region of the turning point 9a including a part of the cut line 11, and includes a guide channel 12 that guides liquid downward.
　この構成によれば、筒状断熱部材１０は、切れ目１１を開いて冷媒配管９に容易に取り付けられる。また、筒状断熱部材１０は、筒状断熱部材１０の取付後に内部に浸入する結露水などの液体を切れ目１１から案内流路１２に流して下方に案内できる。したがって、筒状断熱部材１０が冷媒配管９の接続後に作業効率が良く容易に取り付けられるとともに、結露水などの液体が表面から散らばって流れ落ちない。 According to this configuration, the tubular heat insulating member 10 is easily attached to the refrigerant pipe 9 with the cut 11 opened. In addition, the tubular heat insulating member 10 can guide a liquid such as condensed water that enters inside after the tubular heat insulating member 10 is attached to the guide channel 12 through the cut line 11 and guide it downward. Therefore, the cylindrical heat insulating member 10 is easily attached with good working efficiency after the refrigerant pipe 9 is connected, and liquid such as condensed water is scattered from the surface and does not flow down.
　実施の形態１によれば、切れ目１１は、上半体１０ｃにおける冷媒配管９の湾曲部の内側に形成される。 According to Embodiment 1, the cut line 11 is formed inside the curved portion of the refrigerant pipe 9 in the upper half body 10c.
　この構成によれば、筒状断熱部材１０は、筒状断熱部材１０の取付後に内部に浸入する結露水などの液体を案内流路１２に繋がらない箇所の切れ目１１からあふれさせ難い。つまり、結露水などの液体は、切れ目１１から案内流路１２に案内され易い。この結果、結露水などの液体が筒状断熱部材１０の表面から散らばって流れ落ちない。 According to this configuration, it is difficult for the tubular heat insulating member 10 to overflow liquid such as condensed water that enters inside after the tubular heat insulating member 10 is attached to the guide channel 12 from the cut 11. That is, liquid such as condensed water is easily guided from the cut 11 to the guide channel 12. As a result, liquid such as condensed water is scattered from the surface of the tubular heat insulating member 10 and does not flow down.
　実施の形態１によれば、切れ目１１は、延びる方向に直交する断面が半径方向の内側程狭い幅のＶ字状である。 According to the first embodiment, the cut line 11 has a V shape with a cross section orthogonal to the extending direction having a narrower width toward the inner side in the radial direction.
　この構成によれば、筒状断熱部材１０は、冷媒配管９に対して切れ目１１を押し込むだけで容易に取り付けられる。すなわち、切れ目１１の延出方向に直交する断面での外周側の間隔が広い。これにより、筒状断熱部材１０の取付時には、筒状断熱部材１０が冷媒配管９に押し込んで取り付け易い。また、切れ目１１の延出方向に直交する断面での内周側の間隔が狭い。これにより、筒状断熱部材１０の取付後には、筒状断熱部材１０が冷媒配管９から外れ難い。このように、冷媒配管９の組み上がり後に、接着剤を用いること無く、筒状断熱部材１０が冷媒配管９に取り付けられる。 According to this configuration, the tubular heat insulating member 10 can be easily attached simply by pushing the cut 11 into the refrigerant pipe 9. That is, the space | interval of the outer peripheral side in the cross section orthogonal to the extension direction of the cut | interruption 11 is wide. Thereby, at the time of attachment of the cylindrical heat insulating member 10, the cylindrical heat insulating member 10 is easily pushed into the refrigerant pipe 9 and attached. Moreover, the space | interval of the inner peripheral side in the cross section orthogonal to the extension direction of the cut | interruption 11 is narrow. Thereby, after the cylindrical heat insulating member 10 is attached, the cylindrical heat insulating member 10 is unlikely to be detached from the refrigerant pipe 9. Thus, after the refrigerant pipe 9 is assembled, the tubular heat insulating member 10 is attached to the refrigerant pipe 9 without using an adhesive.
　実施の形態１によれば、案内流路１２は、切れ目１１における最下部の位置に接続され、下方に液体を案内する。 According to Embodiment 1, the guide channel 12 is connected to the lowest position in the cut 11 and guides the liquid downward.
　この構成によれば、冷媒配管９は、湾曲部の最下部に折り返し点９ａを有する。筒状断熱部材１０の取付後に内部に浸入する結露水などの液体は、筒状断熱部材１０の最下部に最も溜まる。このため、筒状断熱部材１０は、結露水などの液体を切れ目１１からより効果的に案内流路１２に流せる。 According to this configuration, the refrigerant pipe 9 has the turning point 9a at the lowermost part of the curved portion. Liquid such as condensed water that penetrates into the interior of the tubular heat insulating member 10 after installation is most accumulated in the lowermost portion of the tubular heat insulating member 10. For this reason, the cylindrical heat insulating member 10 can flow a liquid such as condensed water from the cut 11 to the guide channel 12 more effectively.
　実施の形態１によれば、案内流路１２は、切れ目１１から表面の水平方向の最外径位置１２ａより下方まで形成される。 According to the first embodiment, the guide channel 12 is formed from the cut line 11 to a position below the outermost diameter position 12a in the horizontal direction of the surface.
　この構成によれば、切れ目１１から筒状断熱部材１０の水平方向の最外径位置１２ａより下方まで延びる案内流路１２を流れる結露水などの液体は、その後に重力方向に沿って流れ落ちる。この結果、結露水などの液体が筒状断熱部材１０の表面から散らばって流れ落ちない。 According to this configuration, the liquid such as condensed water flowing through the guide channel 12 extending from the cut line 11 to the lower side of the horizontal outermost position 12a of the cylindrical heat insulating member 10 flows down along the direction of gravity thereafter. As a result, liquid such as condensed water is scattered from the surface of the tubular heat insulating member 10 and does not flow down.
　実施の形態１によれば、案内流路１２は、周方向に形成される。 According to the first embodiment, the guide channel 12 is formed in the circumferential direction.
　この構成によれば、筒状断熱部材１０は、冷媒配管９に対して切れ目１１を押し込むだけで取り付けられる。このとき、筒状断熱部材１０の周方向に沿って形成される案内流路１２は、筒状断熱部材１０を中心軸方向に対して直交方向に折り曲げ変形させ、筒状断熱部材１０を押し込み易くする。この結果、筒状断熱部材１０の取付時には、筒状断熱部材１０が冷媒配管９に押し込んでより取り付け易い。 According to this configuration, the tubular heat insulating member 10 is attached simply by pushing the cut 11 into the refrigerant pipe 9. At this time, the guide flow path 12 formed along the circumferential direction of the tubular heat insulating member 10 causes the tubular heat insulating member 10 to be bent and deformed in a direction orthogonal to the central axis direction, so that the tubular heat insulating member 10 is easily pushed in. To do. As a result, when the tubular heat insulating member 10 is attached, the tubular heat insulating member 10 is pushed into the refrigerant pipe 9 and can be attached more easily.
　実施の形態１によれば、案内流路１２は、切れ目１１から下方に向けて１つ形成される。 According to the first embodiment, one guide channel 12 is formed downward from the cut 11.
　この構成によれば、案内流路１２が筒状断熱部材１０の周方向の片側だけに設けられる。そのため、筒状断熱部材１０の片方側だけに結露水などの液体を排出できる。これにより、筒状断熱部材１０の結露水などの液体を排出しない反対側には、結露水などの液体が流れ落ちない。その結果、この反対側に存在する部品配置領域に結露水などの液体がふりかからない。 According to this configuration, the guide channel 12 is provided only on one side of the cylindrical heat insulating member 10 in the circumferential direction. Therefore, liquid such as condensed water can be discharged only on one side of the tubular heat insulating member 10. Thereby, the liquid such as condensed water does not flow down on the opposite side of the cylindrical heat insulating member 10 where the liquid such as condensed water is not discharged. As a result, liquid such as condensed water does not splash on the component arrangement region on the opposite side.
　実施の形態１によれば、冷媒配管９は、Ｕ字状に湾曲して形成される。筒状断熱部材１０の両端の上端部１０ａ、１０ｂは、それぞれが同じ高さまで冷媒配管９を覆うＵ字状である。 According to Embodiment 1, the refrigerant pipe 9 is formed to be curved in a U shape. The upper end portions 10a and 10b at both ends of the tubular heat insulating member 10 are U-shaped so as to cover the refrigerant pipe 9 to the same height.
　この構成によれば、筒状断熱部材１０がＵ字状であり、両端の上端部１０ａ、１０ｂそれぞれが同じ高さである。このため、筒状断熱部材１０が切れ目１１で開き易く、作業者が筒状断熱部材１０を冷媒配管９に取り付け易い。また、筒状断熱部材１０が正逆反対に取り付けられても良く、作業者の取付間違いがなく作業効率が良い。 According to this configuration, the tubular heat insulating member 10 is U-shaped, and the upper end portions 10a and 10b at both ends have the same height. For this reason, the cylindrical heat insulating member 10 is easy to open at the cut line 11, and the operator can easily attach the cylindrical heat insulating member 10 to the refrigerant pipe 9. In addition, the tubular heat insulating member 10 may be attached in the opposite direction, and there is no mistake in installation by the operator, and the working efficiency is good.
　実施の形態１によれば、案内流路１２は、表面を凹ませた溝である。 According to the first embodiment, the guide channel 12 is a groove having a recessed surface.
　この構成によれば、筒状断熱部材１０の最下部の始点１１ａは、案内流路１２を切れ目で構成する場合に比して外側にめくれ難い。これにより、筒状断熱部材１０は、冷媒配管９に密着して外れ難い。 According to this configuration, the lowermost starting point 11a of the tubular heat insulating member 10 is less likely to be turned outward as compared to the case where the guide channel 12 is formed by a cut. Thereby, the cylindrical heat insulation member 10 adheres to the refrigerant | coolant piping 9, and cannot be removed easily.
