Description

本発明は、空気調和機の室内機と、空気調和機の室内機の製造方法と、に関するものである。   The present invention relates to an indoor unit for an air conditioner and a method for manufacturing the indoor unit for an air conditioner.

従来、室内壁面に据え付けられる壁掛け型の空気調和機の室内機として、一対の壁面と、一対の壁面間を左右方向に延びる熱交換器収容溝と、が形成された背面ケースと、熱交換器収容溝の前方に配設された送風ファンと、熱交換ユニットと、を備えたものがある。熱交換ユニットは、上方から送風ファンの前側に延出する前側熱交換器と、上方から送風ファンの後側に延出し、下端部が熱交換器収容溝に収容された後側熱交換器と、前側熱交換器及び後側熱交換器を一体的に固定する熱交換器固定部材と、を有する。近年、高性能化のために、後側熱交換器が拡大される傾向にある（例えば、特許文献１を参照。）。   Conventionally, as an indoor unit of a wall-mounted air conditioner installed on an indoor wall surface, a back case formed with a pair of wall surfaces and a heat exchanger housing groove extending in the left-right direction between the pair of wall surfaces, and a heat exchanger Some have a blower fan disposed in front of the housing groove and a heat exchange unit. The heat exchange unit includes a front heat exchanger extending from above to the front side of the blower fan, a rear heat exchanger extending from above to the rear side of the blower fan, and a lower end portion accommodated in the heat exchanger accommodating groove, And a heat exchanger fixing member that integrally fixes the front heat exchanger and the rear heat exchanger. In recent years, rear heat exchangers tend to be expanded for higher performance (see, for example, Patent Document 1).

特開２００７−６４６２３号公報（段落［００１４］〜段落［００４３］、図１〜図１４）JP 2007-64623 A (paragraph [0014] to paragraph [0043], FIGS. 1 to 14)

従来の空気調和機の室内機では、背面ケースを室内壁面に据え付けられる状態と同様の状態に起こし、熱交換ユニットを上方から覆い被せるように取り付けるため、背面ケースが不安定であることに起因して、熱交換ユニットの背面ケースへの取り付けが不確実であり、また、その取り付けの作業性が低い。また、背面ケースを安定化させるために、背面ケースを起こした状態で維持する治具を用いることも可能であるが、治具の着脱の分だけ、組立工程が増えてしまう。つまり、従来の空気調和機の室内機では、熱交換ユニットの背面ケースへの取り付け作業が、不確実で且つ困難であり、また、組立工程を増やさざるを得ないという問題点があった。   In the conventional indoor unit of an air conditioner, the rear case is caused to be in a state similar to the state where it is installed on the wall surface of the room, and the heat exchange unit is mounted so as to cover it from above. Therefore, the mounting of the heat exchange unit to the back case is uncertain, and the mounting workability is low. In addition, in order to stabilize the back case, it is possible to use a jig that keeps the back case in a raised state, but the number of assembling steps increases as the jig is attached or detached. That is, in the conventional indoor unit of an air conditioner, it is uncertain and difficult to attach the heat exchange unit to the back case, and there is a problem that the assembly process must be increased.

本発明は、上記のような課題を背景としてなされたものであり、熱交換ユニットの背面ケースへの取り付け作業が確実化及び容易化され、また、組立工程が増えてしまうことが抑制された空気調和機の室内機を得るものである。また、そのような空気調和機の室内機の製造方法を得るものである。   The present invention has been made against the background of the problems described above, and the air mounting operation of the heat exchange unit to the back case is ensured and facilitated, and the number of assembly steps is suppressed from increasing. The indoor unit of a harmony machine is obtained. Moreover, the manufacturing method of such an indoor unit of an air conditioner is obtained.

本発明に係る空気調和機の室内機は、一対の壁面と、前記一対の壁面間を左右方向に延びる熱交換器収容溝と、が形成された背面ケースと、前記熱交換器収容溝の前方に配設された送風ファンと、上方から前記送風ファンの前側に延出する前側熱交換器と、上方から前記送風ファンの後側に延出し、下端部が前記熱交換器収容溝に収容された後側熱交換器と、前記前側熱交換器及び前記後側熱交換器を一体的に固定する熱交換器固定部材と、を有する熱交換ユニットと、を備え、前記一対の壁面のうちの一方の壁面は、前記熱交換器収容溝の端部のうちの少なくとも上側に位置する領域を、覆わない形状である。   An indoor unit of an air conditioner according to the present invention includes a rear case in which a pair of wall surfaces and a heat exchanger accommodating groove extending in the left-right direction between the pair of wall surfaces are formed, and in front of the heat exchanger accommodating groove. A blower fan disposed on the front side, a front heat exchanger extending from the upper side to the front side of the blower fan, and extending from the upper side to the rear side of the blower fan, the lower end portion being housed in the heat exchanger housing groove. A heat exchanger unit having a rear heat exchanger, and a heat exchanger fixing member that integrally fixes the front heat exchanger and the rear heat exchanger, of the pair of wall surfaces, One wall surface is a shape which does not cover the area | region located in the upper side among the edge parts of the said heat exchanger accommodation groove | channel.

本発明に係る空気調和機の室内機では、一対の壁面のうちの一方の壁面が、熱交換器収容溝の端部のうちの少なくとも上側に位置する領域を、覆わない形状である。そのため、背面ケースを寝かした状態であっても、熱交換ユニットを、左右方向の一対の壁面のうちの一方の壁面側から挿入して、背面ケースに取り付けることが可能であるため、熱交換ユニットの背面ケースへの取り付け作業が確実化及び容易化され、また、組立工程が増えてしまうことが抑制される。   In the indoor unit for an air conditioner according to the present invention, one of the pair of wall surfaces has a shape that does not cover at least the region located on the upper side of the end portion of the heat exchanger housing groove. Therefore, even when the back case is laid down, the heat exchange unit can be inserted into one of the pair of left and right wall surfaces and attached to the back case. The attachment work to the back case is ensured and facilitated, and the assembly process is prevented from increasing.

図２及び図３に示されるように、背面ケース１のベース１１の左右方向の両端部には、前方へ突出する一対の壁面（一方の壁面１２、他方の壁面１３）が形成される。送風ファン２は、例えば、クロスフローファンであり、回転軸が左右方向を向く状態で、一方の壁面１２及び他方の壁面１３によって保持される。一方の壁面１２及び他方の壁面１３の間には、送風ファン２の外周面に沿う形状（つまり円弧状）の風路壁１４が形成される。そして、風路壁１４とベース１１との間に、左右方向に延びる熱交換器収容溝１５が形成される。熱交換器収容溝１５の一方の端部１５ａのうちの少なくとも上側に位置する領域は、一方の壁面１２によって覆われない。つまり、背面ケース１の一方の端部１５ａが有る側の壁面１２の上面には、後述する熱交換ユニット３の熱交換器固定板２３の凸部２３ａを、左右方向から通過させて、熱交換器収容溝１５に進入させることができる程度の広さの切り欠きが形成される。また、熱交換器収容溝１５の他方の端部１５ｂのうちの一部の領域は、他方の壁面１３によって覆われる。他方の壁面１３には、後述する熱交換ユニット３の熱交換器固定板２３の凸部２３ａに沿う形状の凹部１３ａが形成される。また、背面ケース１の熱交換器収容溝１５の下側には、左右方向に延びる接続パイプ収容空間１６が形成される。 2 and 3 are perspective views of the back case of the indoor unit of the air conditioner according to Embodiment 1 of the present invention.
As shown in FIGS. 2 and 3, a pair of wall surfaces (one wall surface 12 and the other wall surface 13) projecting forward are formed at both left and right ends of the base 11 of the back case 1. The blower fan 2 is, for example, a cross flow fan, and is held by one wall surface 12 and the other wall surface 13 with the rotation axis facing the left-right direction. Between the one wall surface 12 and the other wall surface 13, an air passage wall 14 having a shape (that is, an arc shape) along the outer peripheral surface of the blower fan 2 is formed. A heat exchanger accommodating groove 15 extending in the left-right direction is formed between the air passage wall 14 and the base 11. A region located at least on the upper side of the one end portion 15 a of the heat exchanger accommodating groove 15 is not covered by the one wall surface 12. That is, the convex part 23a of the heat exchanger fixing plate 23 of the heat exchange unit 3 to be described later is passed from the left and right directions on the upper surface of the wall surface 12 on the side where the one end 15a of the back case 1 is located, so A notch having a width enough to allow entry into the vessel receiving groove 15 is formed. Further, a part of the other end portion 15 b of the heat exchanger housing groove 15 is covered with the other wall surface 13. On the other wall surface 13, a concave portion 13 a having a shape along the convex portion 23 a of the heat exchanger fixing plate 23 of the heat exchange unit 3 described later is formed. In addition, a connection pipe accommodation space 16 extending in the left-right direction is formed below the heat exchanger accommodation groove 15 of the back case 1.

図４は、本発明の実施の形態１に係る空気調和機の室内機の、熱交換ユニットの斜視図である。
図４に示されるように、熱交換ユニット３は、前側熱交換器２１と、後側熱交換器２２と、前側熱交換器２１及び後側熱交換器２２を一体的に固定する熱交換器固定板２３と、前側熱交換器２１及び後側熱交換器２２と室外機の冷媒配管とを接続する接続パイプ２４と、を有する。後側熱交換器２２が、実際に熱交換しないもの、例えばプラスチックで構成されるダミー部品等であってもよい。熱交換器固定板２３は、前側熱交換器２１及び後側熱交換器２２の左右方向の、他方の壁面１３に近い側の端部に、取り付けられる。熱交換器固定板２３の後側熱交換器２２を固定する側には、他方の壁面１３の凹部１３ａに沿う形状の凸部２３ａが形成される。接続パイプ２４は、前側熱交換器２１及び後側熱交換器２２の左右方向の、一方の壁面１２に近い側の端部から延出する。接続パイプ２４には、冷凍サイクルを循環する冷媒が流入する。 FIG. 4 is a perspective view of the heat exchange unit of the indoor unit of the air conditioner according to Embodiment 1 of the present invention.
As shown in FIG. 4, the heat exchange unit 3 includes a front heat exchanger 21, a rear heat exchanger 22, and a heat exchanger that integrally fixes the front heat exchanger 21 and the rear heat exchanger 22. It has the fixed plate 23, the connection pipe 24 which connects the front side heat exchanger 21, the rear side heat exchanger 22, and the refrigerant | coolant piping of an outdoor unit. The rear heat exchanger 22 may be one that does not actually exchange heat, such as a dummy part made of plastic. The heat exchanger fixing plate 23 is attached to the ends of the front side heat exchanger 21 and the rear side heat exchanger 22 on the side close to the other wall surface 13 in the left-right direction. On the side where the rear heat exchanger 22 of the heat exchanger fixing plate 23 is fixed, a convex portion 23a having a shape along the concave portion 13a of the other wall surface 13 is formed. The connection pipe 24 extends from the end of the front side heat exchanger 21 and the rear side heat exchanger 22 on the side close to the one wall surface 12 in the left-right direction. The refrigerant circulating in the refrigeration cycle flows into the connection pipe 24.

図５は、本発明の実施の形態１に係る空気調和機の室内機の、各部材が取り付けられた状態での断面図である。
図５に示されるように、背面ケース１に、送風ファン２と、熱交換ユニット３と、電気品箱４（図示省略）と、吹出口ユニット５と、枠体６と、が取り付けられる。枠体６は、背面ケース１にネジ等で固定される。枠体６に前面意匠パネル７と、フィルター８と、が着脱自在に取り付けられる。 FIG. 5 is a cross-sectional view of the indoor unit of the air conditioner according to Embodiment 1 of the present invention with each member attached.
As shown in FIG. 5, a blower fan 2, a heat exchange unit 3, an electrical component box 4 (not shown), an outlet unit 5, and a frame body 6 are attached to the rear case 1. The frame body 6 is fixed to the back case 1 with screws or the like. A front design panel 7 and a filter 8 are detachably attached to the frame body 6.

送風ファン２は、左右方向に延びる熱交換器収容溝１５の前側に配設される。また、熱交換ユニット３の前側熱交換器２１は、上方から送風ファン２の前側に延出するように配設され、熱交換ユニット３の後側熱交換器２２は、上方から送風ファン２の後側に延出し、下端部が熱交換器収容溝１５に収容されるように配設される。また、接続パイプ２４は、接続パイプ収容空間１６に収容される。   The blower fan 2 is disposed on the front side of the heat exchanger housing groove 15 extending in the left-right direction. The front heat exchanger 21 of the heat exchange unit 3 is disposed so as to extend from the upper side to the front side of the blower fan 2, and the rear heat exchanger 22 of the heat exchange unit 3 is arranged from the upper side of the blower fan 2. It extends rearward and is disposed so that its lower end is accommodated in the heat exchanger accommodating groove 15. Further, the connection pipe 24 is accommodated in the connection pipe accommodation space 16.

送風ファン２が駆動すると、枠体６の上面に形成された吸入口６ａから室内空気が吸い込まれ、熱交換ユニット３の前側熱交換器２１及び後側熱交換器２２で冷媒と熱交換して冷気、暖気等となり、その冷気、暖気等が、吹出口ユニット５の左右風向調整板５ａ及び上下風向調整板５ｂを介して室内に送風される。左右風向調整板５ａ及び上下風向調整板５ｂの向きが調整されることで、その冷気、暖気等の風向が調整される。   When the blower fan 2 is driven, room air is sucked from the suction port 6a formed on the upper surface of the frame body 6, and heat is exchanged with the refrigerant in the front heat exchanger 21 and the rear heat exchanger 22 of the heat exchange unit 3. The air becomes cool air, warm air, and the like, and the cool air, warm air, and the like are blown into the room through the left and right airflow direction adjusting plates 5a and the upper and lower airflow direction adjusting plates 5b. By adjusting the directions of the left and right wind direction adjusting plates 5a and the up and down air direction adjusting plates 5b, the wind directions such as cold air and warm air are adjusted.

図６及び図７は、本発明の実施の形態１に係る空気調和機の室内機の、熱交換ユニットの取り付け方を説明するための図である。なお、図６では、熱交換ユニット３の取り付け作業が途中の状態を示しており、図７では、熱交換ユニット３の取り付け作業が完了した状態を示している。
図６及び図７に示されるように、寝かされた状態の背面ケース１に、送風ファン２を載せ、熱交換ユニット３の熱交換器固定板２３が取り付けられた側を先頭にして、熱交換ユニット３の熱交換器固定板２３の凸部２３ａを熱交換器収容溝１５の一方の端部１５ａに左右方向から挿入するとともに、熱交換ユニット３の接続パイプ２４を接続パイプ収容空間１６に左右方向から挿入して、スライドさせる。熱交換器収容溝１５の一方の端部１５ａのうちの少なくとも上側に位置する領域が、一方の壁面１２によって覆われないため、熱交換ユニット３の熱交換器固定板２３の凸部２３ａを容易に挿入することができる。 6 and 7 are diagrams for explaining how to install the heat exchange unit in the indoor unit of the air-conditioning apparatus according to Embodiment 1 of the present invention. In addition, in FIG. 6, the attachment operation | work of the heat exchange unit 3 is shown in the middle, and the state which the attachment operation | work of the heat exchange unit 3 was completed in FIG. 7 is shown.
As shown in FIGS. 6 and 7, the blower fan 2 is placed on the back case 1 in a laid state, and the heat exchanger fixing plate 23 of the heat exchange unit 3 is attached to the head, The protrusion 23a of the heat exchanger fixing plate 23 of the exchange unit 3 is inserted into one end 15a of the heat exchanger housing groove 15 from the left and right directions, and the connection pipe 24 of the heat exchange unit 3 is inserted into the connection pipe housing space 16. Insert from left and right and slide. Since at least the region located on the upper side of the one end portion 15a of the heat exchanger housing groove 15 is not covered by the one wall surface 12, the convex portion 23a of the heat exchanger fixing plate 23 of the heat exchange unit 3 can be easily formed. Can be inserted into.

特に、図７に示される状態で側面視した場合に、背面ケース１の他方の壁面１３以外の箇所が、熱交換器固定板２３と重ならない状態であると、熱交換ユニット３を左右方向に真っ直ぐ挿入してスライドさせることが可能となるため、熱交換ユニット３の熱交換器固定板２３の凸部２３ａを挿入することと、熱交換ユニット３をスライドさせることと、が更に容易化される。つまり、左右方向と直交する面で背面ケース１を切断して得られる断面図形の輪郭線と、熱交換ユニット３のうちの、その面を基準とする他方の壁面１３側の領域を、その面に投影して得られる投影図形の輪郭線と、が重ならないことが、左右方向の各位置を通る面それぞれにおいて満たされる場合に、熱交換ユニット３を挿入することと、熱交換ユニット３をスライドさせることと、が更に容易化される。   In particular, when viewed from the side in the state shown in FIG. 7, when the portion other than the other wall surface 13 of the back case 1 does not overlap the heat exchanger fixing plate 23, the heat exchange unit 3 is moved in the left-right direction. Since it can be inserted and slid, it is further facilitated to insert the convex portion 23a of the heat exchanger fixing plate 23 of the heat exchange unit 3 and to slide the heat exchange unit 3. . That is, the contour line of the cross-sectional figure obtained by cutting the back case 1 along a plane orthogonal to the left-right direction, and the region of the heat exchange unit 3 on the other wall surface 13 side with respect to that plane When the fact that the outline of the projection figure obtained by projecting onto the plane does not overlap is satisfied in each of the planes passing through the respective positions in the left-right direction, the heat exchange unit 3 is inserted and the heat exchange unit 3 is slid Making it even easier.

図８は、本発明の実施の形態１に係る空気調和機の室内機の、背面ケースの壁面に形成された凹部と熱交換ユニットの熱交換器固定板に形成された凸部との関係を説明するための図である。
図８に示されるように、図７に示されるような状態になると、熱交換ユニット３の熱交換器固定板２３の凸部２３ａは、背面ケース１の壁面１３の凹部１３ａに嵌合して、前側熱交換器２１及び後側熱交換器２２を介さずに、送風ファン２に至る風路を遮断する。 FIG. 8 shows the relationship between the concave portion formed on the wall surface of the back case and the convex portion formed on the heat exchanger fixing plate of the heat exchange unit of the indoor unit of the air conditioner according to Embodiment 1 of the present invention. It is a figure for demonstrating.
As shown in FIG. 8, when the state shown in FIG. 7 is reached, the convex portion 23 a of the heat exchanger fixing plate 23 of the heat exchange unit 3 is fitted into the concave portion 13 a of the wall surface 13 of the back case 1. The air path to the blower fan 2 is blocked without going through the front heat exchanger 21 and the rear heat exchanger 22.

＜空気調和機の室内機の作用＞
実施の形態１に係る空気調和機の室内機の作用について説明する。
空気調和機の室内機１００では、一方の壁面１２が、熱交換器収容溝１５の一方の端部１５ａのうちの少なくとも上側に位置する領域を、覆わない形状である。従来の空気調和機の室内機では、一方の壁面１２が、熱交換器収容溝１５の一方の端部１５ａのうちの全領域を、左右方向から覆う形状であったため、熱交換ユニット３を、左右方向から挿入して取り付けることができなかった。一方、空気調和機の室内機１００では、熱交換ユニット３を、左右方向の一方の壁面１２側から挿入して、背面ケース１に取り付けることが可能であるため、背面ケース１を寝かした状態で熱交換ユニット３を取り付けることが可能となって、熱交換ユニット３の背面ケース１への取り付け作業が確実化及び容易化され、また、組立工程が増えてしまうことが抑制される。なお、特に、空気調和機の室内機１００が、後側熱交換器２２が拡大されたものである程、上述の効果が顕著となる。 <Operation of air conditioner indoor unit>
The operation of the indoor unit of the air conditioner according to Embodiment 1 will be described.
In the indoor unit 100 of the air conditioner, the one wall surface 12 has a shape that does not cover at least the region located on the upper side of the one end portion 15a of the heat exchanger housing groove 15. In the conventional indoor unit of an air conditioner, one wall surface 12 has a shape that covers the entire region of one end portion 15a of the heat exchanger housing groove 15 from the left-right direction. I couldn't insert it from the left-right direction. On the other hand, in the indoor unit 100 of the air conditioner, the heat exchange unit 3 can be inserted from one wall 12 side in the left-right direction and attached to the back case 1, so that the back case 1 is laid down. The heat exchange unit 3 can be attached, and the work of attaching the heat exchange unit 3 to the back case 1 is ensured and facilitated, and the assembly process is prevented from increasing. In particular, in the indoor unit 100 of the air conditioner, the above-described effect becomes more remarkable as the rear heat exchanger 22 is enlarged.

また、空気調和機の室内機１００では、左右方向と直交する面で背面ケース１を切断し得られる断面図形の輪郭線と、熱交換ユニット３のうちの、その面を基準とする他方の壁面１３側の領域を、その面に投影して得られる投影図形の輪郭線と、が重ならないことが、左右方向の各位置を通る面それぞれにおいて満たされる。そのため、熱交換ユニット３を左右方向に真っ直ぐ挿入してスライドさせることが可能となるため、熱交換ユニット３を挿入することと、熱交換ユニット３をスライドさせることと、が更に容易化される。   Moreover, in the indoor unit 100 of an air conditioner, the outline of the cross-sectional figure obtained by cutting the back case 1 along a plane orthogonal to the left-right direction and the other wall surface of the heat exchange unit 3 on the basis of that plane It is satisfied in each of the surfaces passing through the respective positions in the left-right direction that the region on the 13th side does not overlap with the contour line of the projected figure obtained by projecting the region on the surface. Therefore, the heat exchange unit 3 can be inserted and slid straight in the left-right direction, so that the insertion of the heat exchange unit 3 and the sliding of the heat exchange unit 3 are further facilitated.

また、空気調和機の室内機１００では、熱交換ユニット３の熱交換器固定板２３の凸部２３ａが、背面ケース１の壁面１３の凹部１３ａに嵌合して、前側熱交換器２１及び後側熱交換器２２を介さずに、送風ファン２に至る風路を遮断する。そのため、背面ケース１に形成された左右方向に延びる円弧状の風路壁１４と、壁面１３と、熱交換器固定板２３と、が、前側熱交換器２１及び後側熱交換器２２を介して送風ファン２に至る風路を、一体的に形成することとなって、前側熱交換器２１及び後側熱交換器２２を通過しない空気が、送風ファン２に流入することが抑制される。そして、前側熱交換器２１及び後側熱交換器２２で熱交換していない空気が、送風ファン２に流入して、送風ファン２に露が付着して空調空間に露が垂れること等が抑制されて、空気調和機の室内機１００が高品質化される。   Further, in the indoor unit 100 of the air conditioner, the convex portion 23a of the heat exchanger fixing plate 23 of the heat exchange unit 3 is fitted into the concave portion 13a of the wall surface 13 of the rear case 1, and the front heat exchanger 21 and the rear heat exchanger 21 are arranged. The air path leading to the blower fan 2 is blocked without going through the side heat exchanger 22. Therefore, the arcuate air passage wall 14 formed in the back case 1 and extending in the left-right direction, the wall surface 13, and the heat exchanger fixing plate 23 are interposed via the front heat exchanger 21 and the rear heat exchanger 22. Thus, the air path reaching the blower fan 2 is integrally formed, and air that does not pass through the front heat exchanger 21 and the rear heat exchanger 22 is suppressed from flowing into the blower fan 2. And the air which is not heat-exchanged with the front side heat exchanger 21 and the rear side heat exchanger 22 flows in into the ventilation fan 2, and it suppresses that a dew adheres to the ventilation fan 2 and a dew hangs down to an air-conditioning space etc. Thus, the quality of the indoor unit 100 of the air conditioner is improved.

また、空気調和機の室内機１００では、背面ケース１の熱交換器収容溝１５の下側に、左右方向に延びる接続パイプ収容空間１６が形成され、熱交換ユニット３は、前側熱交換器２１及び後側熱交換器２２の左右方向の、一方の壁面１２に近い側の端部から接続パイプ収容空間１６に延出する接続パイプ２４を有する。つまり、空気調和機の室内機１００では、接続パイプ２４を取り付けた状態で、熱交換ユニット３を背面ケース１に左右方向から取り付けることが可能であるため、熱交換ユニット３の背面ケース１への取り付け作業が更に確実化及び容易化され、また、組立工程が増えてしまうことが更に抑制される。   Moreover, in the indoor unit 100 of the air conditioner, a connection pipe housing space 16 extending in the left-right direction is formed below the heat exchanger housing groove 15 of the back case 1, and the heat exchange unit 3 includes the front heat exchanger 21. And the connection pipe 24 extended in the connection pipe accommodation space 16 from the edge part of the side near the one wall surface 12 of the left-right direction of the rear side heat exchanger 22 is provided. That is, in the indoor unit 100 of the air conditioner, since the heat exchange unit 3 can be attached to the back case 1 from the left and right directions with the connection pipe 24 attached, the heat exchange unit 3 is attached to the back case 1. The mounting operation is further ensured and facilitated, and the assembly process is further prevented from increasing.
