Description

空気調和機Air conditioner
　本発明は空気調和機に関する。 The present invention relates to an air conditioner.
　一般に空気調和機の室内機は、吸込口と、熱交換器と、クロスフローファンと、吹出口と、を備え、吸込口から吸い込んだ空気は熱交換器で熱交換される。その後、クロスフローファンなどの送風装置の働きで、熱交換された空気が吹出口から室内へ吹き出される。このとき熱交換器の制御によって、熱交換器の温度が変わり、室内に冷たい空気や暖かい空気を吹き出す。 　In general, the indoor unit of an air conditioner is equipped with a suction port, a heat exchanger, a crossflow fan, and a blowout port, and the air sucked from the suction port is heat-exchanged by the heat exchanger. After that, the air that has undergone heat exchange is blown out into the room from the air outlet by the action of the blower such as the cross flow fan. At this time, the temperature of the heat exchanger is changed by the control of the heat exchanger, and cold air or warm air is blown into the room.
　図１２に示すように、従来の空気調和機は、吸込口１０１と吹出口１０２を有する室内機本体１０３内に熱交換器（図示せず）と送風ファン（図示せず）とを備える。さらに、この空気調和機は、熱交換器の前面部に制御ユニット１０４を備えている。そのため、旧来、制御ユニット１０４を設けていた室内機本体１０３の側方部分１０３ａにスペースが空いている。そして、この空気調和機は、側方部分１０３ａの空いたスペースに熱交換器の長手方向の幅を伸ばして設けることで熱交換効率を向上させている（例えば、特許文献１参照）。 As shown in FIG. 12, the conventional air conditioner includes a heat exchanger (not shown) and a blower fan (not shown) in an indoor unit main body 103 having an inlet 101 and an outlet 102. Further, the air conditioner includes a control unit 104 on the front surface of the heat exchanger. Therefore, there is a space in the side portion 103a of the indoor unit main body 103 where the control unit 104 is conventionally provided. In this air conditioner, the heat exchange efficiency is improved by extending the width of the heat exchanger in the longitudinal direction in the empty space of the side portion 103a (see, for example, Patent Document 1).
　しかしながら、熱交換器の長手方向の幅を伸ばすことには限界がある。熱交換器の長手方向の幅を伸ばすと、熱交換器の端面と室内機本体１０３の側面との空間が小さくなる。そのため、室内機本体１０３の側面を下向きに落下した場合に生じる熱交換器の瞬間的な動きによって、熱交換器が室内機本体１０３の側面に衝突する。すると、衝突により室内機本体１０３の側面が変形する。したがって、熱交換器の長手方向の幅を伸ばすことができず。省エネ性を向上させる構造が損なわれることになっていた。 However, there is a limit in extending the width of the heat exchanger in the longitudinal direction. When the width of the heat exchanger in the longitudinal direction is increased, the space between the end surface of the heat exchanger and the side surface of the indoor unit body 103 becomes smaller. Therefore, the heat exchanger collides with the side surface of the indoor unit body 103 due to the instantaneous movement of the heat exchanger that occurs when the side surface of the indoor unit body 103 falls downward. Then, the side surface of the indoor unit body 103 is deformed due to the collision. Therefore, the width of the heat exchanger in the longitudinal direction cannot be increased. The structure that improves energy efficiency was to be compromised.

　本開示は、簡易的な構造で、室内機本体が側面側を下向きに落下した場合においても室内機本体の側面への熱交換器の衝突を防止できる空気調和器を提供する。 The present disclosure provides an air conditioner with a simple structure that can prevent the heat exchanger from colliding with the side surface of the indoor unit body even when the indoor unit body drops downward on the side surface side.
　本開示は、リアガイダの少なくとも一部を含む筐体部材と、筐体部材に設けられる熱交換器と、を備え、筐体部材が、リアガイダの上方側の先端部分の付近で、かつ、筐体部材の長手方向において熱交換器の第一の端面の位置に相当する位置に受け部突起を備える構成としている。 The present disclosure includes a housing member including at least a part of a rear guider, and a heat exchanger provided in the housing member, wherein the housing member is near an upper end portion of the rear guider and the housing. The receiving projection is provided at a position corresponding to the position of the first end surface of the heat exchanger in the longitudinal direction of the member.
　受け部突起を備えるため、室内機本体が受け部突起側を下向きに落下した場合であっても、熱交換器の荷重は受け部突起により受け止められる。これにより、熱交換器の落下方向へ瞬間的動きを低減できる。そのため、熱交換器を長手方向に延長した場合においても、熱交換器と室内機本体との衝突が防止でき、熱交換器の第一の端面から突出している配管の変形を防止できる。さらに、熱交換器と室内機本体の筐体の長手方向の隙間の間隙寸法を小さくして、熱交換器を長手方向に長くすることができる。そのため、熱交換性能を向上することができるとともに、吹き出し空気を室内の幅広い領域に送風することができる。 ㆍSince it has a receiving part protrusion, even if the indoor unit body falls downward on the receiving part protrusion side, the load of the heat exchanger is received by the receiving part protrusion. This can reduce the instantaneous movement of the heat exchanger in the falling direction. Therefore, even when the heat exchanger is extended in the longitudinal direction, it is possible to prevent the heat exchanger from colliding with the indoor unit body and prevent deformation of the pipe projecting from the first end surface of the heat exchanger. Furthermore, the gap size in the longitudinal direction between the heat exchanger and the housing of the indoor unit main body can be reduced to lengthen the heat exchanger in the longitudinal direction. Therefore, the heat exchange performance can be improved, and the blown air can be blown to a wide area in the room.

The front side heat exchange portion 4b has a substantially V shape.
　筐体部材２ｃは、前面側に曲面形状のリアガイダ２ｃａを備える。リアガイダ２ｃａは、送風ファン５の回転により発生する吹き出し空気の下側の流れを制御する。また、リアガイダ２ｃａに対抗するようにスタビライザ２ｃｂが設けられている。スタビライザ２ｃｂは、送風ファン５の回転により発生する吹き出し空気の上側の流れを制御する。リアガイダ２ｃａとスタビライザ２ｃｂとに前後方向を挟まれ、筐体部材２ｃの側面により左右方向が挟まれた領域が通風路７であり、送風ファン５の回転により発生する吹き出し空気が流れる。 The housing member 2c has a curved rear guider 2ca on the front side.

　また、室内機筐体２の開口部２ａと熱交換器４との間には、開口部２ａから取り入れた室内空気に含まれる塵埃を除去するためのフィルタ１０が設けられている。フィルタ１０は、枠体部分と、その枠体部分に保持された網部分とを備えている。本実施の形態における空気調和機は、フィルタ１０の網部分に付着した塵埃を自動的に清掃するフィルタ掃除ユニット１１を備えている。 A filter 10 for removing dust contained in the indoor air taken in through the opening 2a is provided between the opening 2a of the indoor unit housing 2 and the heat exchanger 4. The filter 10 includes a frame portion and a net portion held by the frame portion. The air conditioner according to the present embodiment includes a filter cleaning unit 11 that automatically cleans dust attached to the mesh portion of the filter 10.
　空気調和機が運転を開始すると、上下風向変更羽根８が開制御されて吹出口６が開放される。この状態で送風ファン５が駆動することで、室内空気が開口部２ａを介して室内機１の内部に取り入れられる。取り入れられた室内空気は、熱交換器４で熱交換され、送風ファン５を通過し、送風ファン５の送風方向の下流側に形成された通風路７を通過して、吹出口６より吹き出される。 When the air conditioner starts operation, the up/down wind direction changing vane 8 is controlled to open and the air outlet 6 is opened. By driving the blower fan 5 in this state, room air is taken into the indoor unit 1 through the opening 2a. The taken-in indoor air is heat-exchanged by the heat exchanger 4, passes through the blower fan 5, passes through the ventilation passage 7 formed on the downstream side of the blower fan 5 in the blowing direction, and is blown out from the blowout port 6. It
　図４に示すように、熱交換器４は、複数のフィン１２と複数のフィン１２を貫通する配管１３と貫通する配管１３同士をＵ字状に繋ぐＵ字状の接続配管１３ａとで構成されている。室外機から伸びる冷媒を流す配管は、室内機１に繋がる。室内機１の入り口では、配管集合部１３ｃのように、入口側と出口側の冷媒配管が一本ずつ設けられている。配管集合部１３ｃの付近に配管連結部１３ｂを設け、冷媒配管は配管連結部１３ｂで複数の冷媒配管に分岐する。分岐した冷媒配管はそれぞれ、複数のフィン１２を貫通する配管１３に接続される。配管１３は、複数のフィン１２の積層方向に直線状に長い構造である。そして、複数のフィン１２を貫通した配管１３は、別の配管１３と、接続配管１３ａで接続され、冷媒流路が複数のフィン１２の積層方向で折り返すように構成されている。 As shown in FIG. 4, the heat exchanger 4 is composed of a plurality of fins 12, a pipe 13 penetrating the plurality of fins 12, and a U-shaped connecting pipe 13a connecting the penetrating pipes 13 in a U-shape. ing.

A pipe connecting portion 13b is provided near the pipe collecting portion 13c, and the refrigerant pipe branches into a plurality of refrigerant pipes at the pipe connecting portion 13b. The branched refrigerant pipes are connected to pipes 13 that pass through the plurality of fins 12, respectively. The pipe 13 is linearly long in the stacking direction of the plurality of fins 12. The pipe 13 penetrating the plurality of fins 12 is connected to another pipe 13 by a connection pipe 13a so that the refrigerant flow path is folded back in the stacking direction of the plurality of fins 12.
　図５は室内機１の室内機筐体２と、室内機筐体２に保持された熱交換器４の平面図であり、図６は室内機１の室内機筐体２と、室内機筐体２に保持された熱交換器４の正面図である。図５及び図６に示すように、熱交換器４に設けられるＵ字状の接続配管１３ａは、熱交換器４の長手方向の両側に設けられる。一方、配管連結部１３ｂ及び配管集合部１３ｃは、熱交換器４の長手方向における第一の端面側に設けられる。そのため、熱交換器４は左右非対称の形状となり、配管連結部１３ｂや配管集合部１３ｃが設けられる長手方向の第一の端面側の冷媒配管は、突出し、接続配管１３ａで構成された側よりも変形しやすい構造となる。 5 is a plan view of the indoor unit housing 2 of the indoor unit 1 and the heat exchanger 4 held by the indoor unit housing 2. FIG. 6 is an indoor unit housing 2 of the indoor unit 1 and the indoor unit housing. It is a front view of the heat exchanger 4 held by the body 2. As shown in FIGS. 5 and 6, the U-shaped connection pipes 13 a provided in the heat exchanger 4 are provided on both sides of the heat exchanger 4 in the longitudinal direction. On the other hand, the pipe connecting portion 13b and the pipe collecting portion 13c are provided on the first end face side in the longitudinal direction of the heat exchanger 4. Therefore, the heat exchanger 4 has a left-right asymmetrical shape, and the refrigerant pipe on the first end face side in the longitudinal direction in which the pipe connecting portion 13b and the pipe collecting portion 13c are provided protrudes more than the side formed by the connecting pipe 13a. The structure is easily deformed.
　図７は室内機１の室内機筐体２の斜視図であり、図８は室内機１の室内機筐体２から側板を切除した状態の斜視図である。また、図９は室内機１の室内機筐体２の要部拡大斜視図である。 FIG. 7 is a perspective view of the indoor unit housing 2 of the indoor unit 1, and FIG. 8 is a perspective view of the indoor unit housing 2 of the indoor unit 1 with a side plate removed. Further, FIG. 9 is an enlarged perspective view of a main part of the indoor unit housing 2 of the indoor unit 1.
　図７～図９に示すように、熱交換器４を固定保持する室内機筐体２における背面側熱交換部４ａの右側コーナ部と対向する部分には、受け部突起１４を一体形成している。言い換えると、リアガイダ２ｃａの上方側の先端部分の付近で、かつ、筐体部材２ｃの長手方向において熱交換器４の第一の端面の位置に相当する位置に受け部突起１４を備える。受け部突起１４には背面側熱交換部４ａの第一の端面である右側端部、例えば、フィン１２のフィン面を当接させる。受け部突起１４は室内機筐体２の背面側熱交換部４ａを支持する支持段部１５の端部に隆起する形で形成してある。そして、受け部突起１４は、背面側熱交換部４ａと当接する側とは反対側に補強リブ１６を立設形成して強度を向上させている。なお、補強リブ１６を複数設けることでさらに強度を向上することができる。 As shown in FIG. 7 to FIG. 9, a receiving portion projection 14 is integrally formed on a portion of the indoor unit housing 2 that holds the heat exchanger 4 fixedly, facing the right side corner portion of the rear heat exchange portion 4a. There is. In other words, the receiving protrusion 14 is provided near the upper end of the rear guider 2ca and at a position corresponding to the position of the first end surface of the heat exchanger 4 in the longitudinal direction of the housing member 2c. A right end portion, which is the first end surface of the rear side heat exchange portion 4a, for example, a fin surface of the fin 12 is brought into contact with the receiving projection 14. The receiving portion projection 14 is formed in a shape that bulges at the end of the support step portion 15 that supports the rear surface side heat exchange portion 4a of the indoor unit housing 2. The receiving portion projection 14 has a reinforcing rib 16 formed upright on the side opposite to the side in contact with the rear heat exchange portion 4a to improve the strength. The strength can be further improved by providing a plurality of reinforcing ribs 16.
　ここで、受け部突起１４は、図９に示すように略三角柱の形状をしている。特に図９には受け部突起１４が略直角三角形の底面を有する略三角柱の形状としている。図９に示す受け部突起１４は略直角三角形の形状をした面が室内機１の前面側と背面側を向くように設けられている。このように設けることで、室内機１が受け部突起１４を下側にして落下した際に、落下の衝撃が室内機１の側板２ｂから室内機筐体２に伝わり、さらに室内機筐体２から受け部突起１４に伝わる。続いて受け部突起１４から熱交換器４の第一の端面、例えばフィンに伝わる。そのため、落下の衝撃が側板２ｂから直接、配管１３、特に配管連結部１３ｂや配管集合部１３ｃに伝わることを低減できるため、配管連結部１３ｂや配管集合部１３ｃの変形を抑えることができる。 Here, the receiving portion projection 14 has a substantially triangular prism shape as shown in FIG. In particular, in FIG. 9, the receiving portion protrusion 14 has a substantially triangular prism shape having a bottom surface of a substantially right triangle. The receiving portion projection 14 shown in FIG. 9 is provided so that the surfaces in the shape of a substantially right triangle face the front side and the back side of the indoor unit 1. By providing in this way, when the indoor unit 1 falls with the receiving portion projection 14 on the lower side, the impact of the drop is transmitted from the side plate 2b of the indoor unit 1 to the indoor unit housing 2, and further the indoor unit housing 2 Is transmitted to the receiving projection 14. Then, the heat is transmitted from the receiving projection 14 to the first end surface of the heat exchanger 4, for example, the fin. Therefore, it is possible to reduce the impact of the drop from being directly transmitted from the side plate 2b to the pipe 13, particularly the pipe connecting portion 13b or the pipe collecting portion 13c, and thus it is possible to suppress the deformation of the pipe connecting portion 13b or the pipe collecting portion 13c.
　図１０は室内機１の熱交換器４を一部割愛して示す正面図であり、図１１は図１０におけるＡ部の拡大断面図である。図６で示したように、熱交換器４の配管連結部１３ｂの反対側端部である熱交換器４の第二の端面ではＵ字状の接続配管１３ａが複数並んでいる。そして図１１に示すように、正面から見た際にＵ字状の接続配管１３ａの下側に室内機筐体２に固定された水受け皿等の水受け部品１８が設けられている。 FIG. 10 is a front view showing a part of the heat exchanger 4 of the indoor unit 1 omitted, and FIG. 11 is an enlarged sectional view of a portion A in FIG. As shown in FIG. 6, a plurality of U-shaped connecting pipes 13a are arranged on the second end surface of the heat exchanger 4, which is the opposite end of the pipe connecting portion 13b of the heat exchanger 4. As shown in FIG. 11, a water receiving component 18 such as a water receiving tray fixed to the indoor unit housing 2 is provided below the U-shaped connecting pipe 13a when viewed from the front.
　本実施の形態では図１１に示すように、正面から見た際に熱交換器４の端部にＵ字状の接続配管１３ａを覆うカバー１９を設けている。そして、カバー１９の熱交換器４側は、図示していないが、熱交換器４の第二の端面、例えばフィン１２に当接している。カバー１９の端縁を室内機本体構成部品となる水受け部品１８の縦壁部１８ａに対向させ当接させてある。さらにカバー１９の側面は、側板２ｂの方向に突出している。そのため、接続配管１３ａよりもカバー１９の方が熱交換器４から離間する方向に延びている。これにより、室内機１がカバー１９を下向きにして落下した際は、カバー１９の方が接続配管１３ａよりも先に衝撃を受け、その衝撃を熱交換器４の第二の端面、例えばフィン１２に伝達する。そのため、接続配管１３ａに直接衝撃が伝わることを低減でき、接続配管１３ａの変形を抑えることができる。 In this embodiment, as shown in FIG. 11, a cover 19 is provided at the end of the heat exchanger 4 to cover the U-shaped connection pipe 13a when viewed from the front. Although not shown, the heat exchanger 4 side of the cover 19 is in contact with the second end surface of the heat exchanger 4, for example, the fin 12. The edge of the cover 19 is made to face and abut the vertical wall portion 18a of the water receiving component 18 which is a constituent component of the indoor unit main body. Furthermore, the side surface of the cover 19 projects toward the side plate 2b. Therefore, the cover 19 extends in a direction away from the heat exchanger 4 rather than the connection pipe 13a. As a result, when the indoor unit 1 drops with the cover 19 facing downward, the cover 19 receives an impact earlier than the connecting pipe 13a, and the impact is applied to the second end surface of the heat exchanger 4, for example, the fins 12. Communicate to. Therefore, it is possible to reduce the direct transmission of the impact to the connection pipe 13a and suppress the deformation of the connection pipe 13a.
　次に上記のように構成した空気調和機において、その作用効果を説明する。 Next, the function and effect of the air conditioner configured as described above will be explained.
　本実施の形態の空気調和機は、熱交換器４の全長を室内機筐体２の横幅のほぼ全域に長手方向に延長できる。そのため、図６に示すように、熱交換器４の第一の端面から突出している配管連結部１３ｂの配管集合部１３ｃと室内機筐体２の側板２ｂとの間の間隙が狭いものとなっている。 In the air conditioner of the present embodiment, the entire length of the heat exchanger 4 can be extended in the longitudinal direction over almost the entire width of the indoor unit housing 2. Therefore, as shown in FIG. 6, the gap between the pipe collecting portion 13c of the pipe connecting portion 13b protruding from the first end surface of the heat exchanger 4 and the side plate 2b of the indoor unit housing 2 becomes narrow. ing.
　しかしながら、本実施の形態における空気調和機は、室内機筐体２の配管連結部１３ｂ側の熱交換器４の第一の端面、例えばフィン１２の面が図８、図９に示す受け部突起１４に当接している。そのため、配管連結部１３ｂ側を下にして室内機筐体２が落下した場合であっても、熱交換器４の荷重はフィン１２に当接している受け部突起１４により受け止める。 However, in the air conditioner according to the present embodiment, the first end surface of the heat exchanger 4 on the pipe connection portion 13b side of the indoor unit housing 2, for example, the surface of the fin 12 has the receiving portion projection shown in FIGS. 8 and 9. It is in contact with 14. Therefore, even when the indoor unit housing 2 is dropped with the pipe connecting portion 13b side down, the load of the heat exchanger 4 is received by the receiving portion projection 14 that is in contact with the fin 12.
　これにより、熱交換器４が落下方向へ瞬間的に動くことを低減することができる。そのため、熱交換器４の全長を長くして熱交換器端部と室内機本体の一部を構成する室内機本体構成部品との間の間隙寸法を小さくしても、熱交換器４の第一の端面にある配管１３、例えば配管連結部１３ｂや配管集合部１３ｃの変形を防止できる。そして、この変形防止とともに、熱交換器４の第一の端面と室内機筐体の一部を構成する筐体部材２ｃとの間の間隙寸法を小さくできる。そして、間隙寸法を小さくした距離に合わせて熱交換器４の全長を長くすることができるため、熱交換性能を向上させることができる。 By this, it is possible to reduce the momentary movement of the heat exchanger 4 in the falling direction. Therefore, even if the total length of the heat exchanger 4 is increased to reduce the gap size between the end portion of the heat exchanger and the indoor unit main body component that constitutes a part of the indoor unit main body, It is possible to prevent deformation of the pipe 13 on one end face, for example, the pipe connecting portion 13b and the pipe collecting portion 13c. In addition to this deformation prevention, the size of the gap between the first end surface of the heat exchanger 4 and the housing member 2c forming a part of the indoor unit housing can be reduced. Then, since the total length of the heat exchanger 4 can be increased according to the distance with the reduced gap size, the heat exchange performance can be improved.
　特に本実施の形態では、受け部突起１４は熱交換器４の第一の端面の側とは反対側に複数の補強リブ１６を立設形成してあるから、受け部突起１４の強度が向上しており、熱交換器４の全長を長くして重量が増えていても、熱交換器４の落下荷重を確実に受け止めることができる。 Particularly, in the present embodiment, since the plurality of reinforcing ribs 16 are formed upright on the side of the receiving portion projection 14 opposite to the first end face side of the heat exchanger 4, the strength of the receiving portion projection 14 is improved. Therefore, even if the total length of the heat exchanger 4 is increased and the weight is increased, the falling load of the heat exchanger 4 can be reliably received.
　これにより、熱交換器４の落下方向への動きを確実に低減することができ、配管連結部１３ｂの配管集合部１３ｃの変形防止効果を確実なものとすることができる。 With this, the movement of the heat exchanger 4 in the falling direction can be reliably reduced, and the deformation preventing effect of the pipe collecting portion 13c of the pipe connecting portion 13b can be ensured.
　また、本実施の形態では、配管連結部１３ｂが位置する熱交換器４の第一の端面の側と反対側の第二の端面の側には、図１１に示すように、配管１３の端部となる接続配管１３ａを覆うカバー１９を設け、このカバー１９を室内機筐体２の一部となる水受け部品１８に当接させた構成としてある。 In addition, in the present embodiment, as shown in FIG. 11, the end of the pipe 13 is provided on the second end face side opposite to the first end face side of the heat exchanger 4 where the pipe connecting portion 13b is located. A cover 19 is provided to cover the connection pipe 13a that serves as a part, and the cover 19 is brought into contact with the water receiving component 18 that is a part of the indoor unit housing 2.
　これにより、室内機筐体２を室内機１の長手方向において配管連結部１３ｂを設ける側を上向きにした状態で落下させた場合であっても、熱交換器４の動きは室内機筐体２の一部を構成する室内機本体構成部品である水受け部品１８に当接させたカバー１９によって低減することができる。熱交換器４の第二の端面側の配管１３のＵ字状の接続配管１３ａが室内機筐体２の筐体部材２ｃに当たり変形することを低減できる。 As a result, even when the indoor unit housing 2 is dropped in the longitudinal direction of the indoor unit 1 with the side on which the pipe connecting portion 13b is provided facing upward, the movement of the heat exchanger 4 does not occur. This can be reduced by the cover 19 that is brought into contact with the water receiving component 18, which is a component of the indoor unit main body that constitutes a part of the above. It is possible to reduce deformation of the U-shaped connecting pipe 13a of the pipe 13 on the second end face side of the heat exchanger 4 hitting the housing member 2c of the indoor unit housing 2 and deforming.
　したがって、熱交換器４の第一の端面を受ける受け部突起１４と熱交換器４の第二の端面を受けるカバー１９とによって熱交換器４の左右両端部における室内機本体の構成部品と、熱交換器４の第一の端面および第二の端面との間の間隙寸法をそれぞれ短くすることができる。そして、間隙寸法を短くした分、熱交換器４を長手方向に延長するでき、熱交換効率を高めることができる。 Therefore, the receiving part projection 14 that receives the first end surface of the heat exchanger 4 and the cover 19 that receives the second end surface of the heat exchanger 4 constitute components of the indoor unit main body at the left and right ends of the heat exchanger 4, The size of the gap between the first end surface and the second end surface of the heat exchanger 4 can be shortened. Then, the heat exchanger 4 can be extended in the longitudinal direction by the amount of shortening the gap size, and the heat exchange efficiency can be improved.
　また、カバー１９の下方には室内機本体構成部品として水受け部品１８を設けてあるから、配管１３のＵ字状の接続配管１３ａから冷輻射影響を受けてカバー１９が低温化し結露が生じることがあっても、この結露水は水受け部品１８が受け止めて所定の場所に排水することができる。したがって、カバー１９を設けて結露水が発生するようになったことによる悪影響を防止しつつ熱交換性能を向上させることができる。 Further, since the water receiving part 18 is provided below the cover 19 as a component of the indoor unit main body, the cover 19 is cooled by the radiation effect of the U-shaped connecting pipe 13a of the pipe 13 and the cover 19 is cooled to cause dew condensation. Even if there is, the condensed water can be received by the water receiving component 18 and discharged to a predetermined place. Therefore, it is possible to improve the heat exchange performance while preventing the adverse effect due to the provision of the cover 19 to generate dew condensation water.
　以上、本開示における空気調和機について、上記実施の形態を用いて説明したが、本開示は、これに限定されるものではなく、本開示の範囲は請求の範囲によって示され、請求の範囲と均等の意味及び範囲内でのすべての変更が含まれるものである。 As above, the air conditioner in the present disclosure has been described using the above embodiment, but the present disclosure is not limited to this, and the scope of the present disclosure is indicated by the claims, and All changes within the meaning and range of equivalence are included.
　以上で説明したように、第１の開示における空気調和器は、リアガイダの少なくとも一部を含む筐体部材と、筐体部材に設けられる熱交換器と、を備え、筐体部材が、リアガイダの上方側の先端部分の付近で、かつ、筐体部材の長手方向において、熱交換器の第一の端面の位置に相当する位置に受け部突起を備える。 As described above, the air conditioner according to the first disclosure includes the housing member including at least a part of the rear guider, and the heat exchanger provided in the housing member, and the housing member is the rear guider. A receiving projection is provided near the upper end and in the longitudinal direction of the housing member at a position corresponding to the position of the first end surface of the heat exchanger.
　この構成により、室内機本体が受け部突起側を下向きに落下した場合であっても、熱交換器の荷重は受け部突起により受け止められる。これにより、熱交換器の落下方向へ瞬間的動きを低減できる。そのため、熱交換器を長手方向に延長した場合においても、熱交換器の第一の端面から突出している配管の変形を防止できる。さらに、熱交換器と室内機本体の筐体の長手方向の隙間の間隙寸法を小さくして、熱交換器を長手方向に延長することができる。そのため、熱交換性能を向上でき、吹き出し空気を室内の幅広い領域に送風することができる。 With this configuration, even if the indoor unit body falls downward on the receiving part protrusion side, the load of the heat exchanger is received by the receiving part protrusion. This can reduce the instantaneous movement of the heat exchanger in the falling direction. Therefore, even when the heat exchanger is extended in the longitudinal direction, it is possible to prevent the deformation of the pipe projecting from the first end surface of the heat exchanger. Further, the size of the longitudinal gap between the heat exchanger and the housing of the indoor unit body can be reduced to extend the heat exchanger in the longitudinal direction. Therefore, the heat exchange performance can be improved and blown air can be blown to a wide area in the room.
　また、第２の開示における空気調和器は、第１の開示において、熱交換器が、複数のフィンと、複数のフィンを貫通する配管と、複数のフィンの積層方向における熱交換器の第一の端面に配管の入口配管と出口配管とが位置し、筐体部材は入口配管と出口配管とが位置する熱交換器の第一の端面の側に受け部突起を備える構成としてもよい。 The air conditioner according to the second disclosure is the air conditioner according to the first disclosure, wherein the heat exchanger has a plurality of fins, a pipe penetrating the plurality of fins, and a first heat exchanger in a stacking direction of the plurality of fins. The inlet pipe and the outlet pipe of the pipe are located on the end face of the housing, and the casing member may be provided with the receiving portion projection on the side of the first end face of the heat exchanger where the inlet pipe and the outlet pipe are located.
　この構成により、室内機本体が落下した際に熱交換器の荷重により変形しやすい側の配管の変形を防止できる。入口配管及び出口配管が設けられた側では、配管が分岐して設けられる等形状が各部分で異なり、衝撃時の耐久性も異なる。そのため、入口配管及び出口配管が設けられた側の方が変形しやすく、入口配管と出口配管とが位置する熱交換器の第一の端面の側に受け部突起を備える構成とすることで、配管の変形を低減することができる。 With this configuration, it is possible to prevent deformation of the piping on the side that is easily deformed by the load of the heat exchanger when the indoor unit body falls. On the side where the inlet pipe and the outlet pipe are provided, the shape in which the pipe is branched is different in each part, and the durability against impact is also different. Therefore, the side where the inlet pipe and the outlet pipe are provided is more likely to be deformed, and by configuring the receiving portion projection on the side of the first end surface of the heat exchanger where the inlet pipe and the outlet pipe are located, The deformation of the pipe can be reduced.
　また、第３の開示における空気調和器は、第２の開示において、熱交換器が、長手方向における第一の端面の反対側である第二の端面側に配管を互いに接続し合うＵ字状の接続配管を備え、接続配管をカバーで覆う構成としてもよい。 The air conditioner according to the third disclosure is the air conditioner according to the second disclosure, wherein the heat exchanger has a U-shape in which pipes are connected to each other on the second end face side opposite to the first end face in the longitudinal direction. The connecting pipe may be provided and the connecting pipe may be covered with a cover.
　この構成により、Ｕ字状の接続配管が複数配置された第二の端面側でも落下衝撃による変形を抑制することができる。 With this configuration, it is possible to suppress deformation due to a drop impact even on the second end face side where a plurality of U-shaped connection pipes are arranged.
　また、第４の開示における空気調和器は、第１～３の開示のいずれかにおいて、受け部突起が、熱交換器の第一の端面の側と反対側に補強リブを備える構成としてもよい。 Further, the air conditioner according to the fourth disclosure may be configured according to any one of the first through third disclosures, in which the receiving portion projection includes a reinforcing rib on the side opposite to the first end face side of the heat exchanger. ..
　この構成により、受け部突起の強度を高くすることができる。そのため、熱交換器を長手方向にさらに延長した場合においても、落下による衝撃を受け部突起が受け止めることができるとともに、熱交換器をさらに延長して、熱交換の能力を高めることができる。 With this configuration, the strength of the receiving projection can be increased. Therefore, even when the heat exchanger is further extended in the longitudinal direction, the impact due to the drop can be received by the projection of the receiving portion, and the heat exchanger can be further extended to enhance the heat exchange capability.
　また、第５の開示における空気調和器は、第１～３の開示において、カバーの下方に筐体部材の水受け部品を備える構成としてもよい。 Further, the air conditioner according to the fifth disclosure may be configured to include the water receiving component of the casing member below the cover in the first to third disclosures.
　また、第６の開示における空気調和器は、第４の開示において、カバーの下方に筐体部材の水受け部品を備える構成としてもよい。 The air conditioner according to the sixth disclosure may be configured such that the water receiving component of the casing member is provided below the cover in the fourth disclosure.
　本開示は、熱交換器の配管の変形を防止しつつ熱交換器を長手方向に延長することができる。そのため、熱交換性能を向上させて省エネ性の高い空気調和機とすることができる。家庭用及び業務用の空気調和機に広く適用することができる。 According to the present disclosure, the heat exchanger can be extended in the longitudinal direction while preventing the deformation of the heat exchanger pipe. Therefore, it is possible to improve the heat exchange performance and provide an air conditioner with high energy saving performance. It can be widely applied to household and commercial air conditioners.
