Description

本発明は、熱交換器室と送風機室とを含む空気調和機に関し、さらに詳しく言えば、熱交換器室内に上下２つの熱交換部をくの字状に連結した熱交換器を有する空気調和機に関するものである。   The present invention relates to an air conditioner including a heat exchanger chamber and a blower chamber, and more specifically, an air conditioner having a heat exchanger in which two upper and lower heat exchange portions are connected in a U-shape in the heat exchanger chamber. Related to the machine.

図９に空気調和機の一形態としてのダクト型空気調和機１Ｂの従来例を示す。ダクト型空気調和機１Ｂの多くは、直方体状の筐体１０を備えている。筐体１０の一方の面側（図９では右側）に空気吸込口１０Ａが設けられ、一方の面と対向する他方の面側（図９では左側）に空気吹出口１０Ｂが設けられている。   FIG. 9 shows a conventional example of a duct type air conditioner 1B as one form of the air conditioner. Many of the duct type air conditioners 1 </ b> B include a rectangular parallelepiped casing 10. An air inlet 10A is provided on one surface side (right side in FIG. 9) of the housing 10, and an air outlet 10B is provided on the other surface side (left side in FIG. 9) opposite to the one surface.

筐体１０の内部は、仕切り板２０によって、空気吸込口１０Ａ側の送風機室３０と、空気吹出口１０Ｂ側の熱交換器室４０とに区画されている。送風機室３０内には、送風機３１が配置されている。   The interior of the housing 10 is partitioned by a partition plate 20 into a blower chamber 30 on the air inlet 10A side and a heat exchanger chamber 40 on the air outlet 10B side. A blower 31 is disposed in the blower chamber 30.

熱交換器室４０内には、熱交換器４１とドレンパン４５とが配置されている。熱交換器室４０は上面に天板４０１を備え、ドレンパン４５は熱交換器室４０の天板４０１と対向する底部４０２に配置されている。   In the heat exchanger chamber 40, a heat exchanger 41 and a drain pan 45 are arranged. The heat exchanger chamber 40 is provided with a top plate 401 on the upper surface, and the drain pan 45 is disposed on the bottom 402 facing the top plate 401 of the heat exchanger chamber 40.

ダクト型空気調和機において、送風機３１には、通常、シロッコファンが採用されている。シロッコファンはスクロールケーシング３２を有する遠心送風機の一種で、風はスクロールケーシング３２の送風口から熱交換器４１の一部分に向けて集中して吹き出される。   In the duct type air conditioner, a sirocco fan is usually employed for the blower 31. The sirocco fan is a kind of centrifugal blower having a scroll casing 32, and wind is concentrated and blown out from the blower opening of the scroll casing 32 toward a part of the heat exchanger 41.

図示しないが、ダクト型空気調和機１Ｂは天井裏（屋根裏）に設置され、空気吸込口１０Ａは、吸込側ダクトを介して天井面に設けられている空気吸込グリルと接続され、空気吹出口１０Ｂは、吹出側ダクトを介して天井面に設けられている空気吹出グリルと接続される。   Although not shown, the duct-type air conditioner 1B is installed in the ceiling (attic), and the air inlet 10A is connected to an air inlet grill provided on the ceiling surface via the inlet duct, and the air outlet 10B. Is connected to an air blowing grill provided on the ceiling surface through a blowing duct.

このダクト型空気調和機１Ｂは、送風機３１が熱交換器４１の上流側に配置され、送風機３１から熱交換器４１に対して空気が吹き付けられる空気調和機であり、送風機（シロッコファン）３１の運転により、室内空気が空気吸込グリル→吸込側ダクト→送風機室３０→熱交換器室４０→吹出側ダクト→空気吹出グリルへと流れ、熱交換器室４０内の熱交換器４１にて熱交換された調和空気が空気吹出グリルから室内に戻される。   The duct type air conditioner 1B is an air conditioner in which the blower 31 is disposed on the upstream side of the heat exchanger 41 and air is blown from the blower 31 to the heat exchanger 41. The blower (sirocco fan) 31 During operation, the indoor air flows from the air suction grill → the suction side duct → the blower chamber 30 → the heat exchanger chamber 40 → the blowout side duct → the air blowout grill, and exchanges heat with the heat exchanger 41 in the heat exchanger chamber 40. The conditioned air is returned from the air blowing grill to the room.

この従来例において、熱交換器４１には、２つの平面状の熱交換器４２，４３を側面視（図９では正面視）でくの字状に組合せた熱交換器が用いられている。   In this conventional example, the heat exchanger 41 is a heat exchanger in which two planar heat exchangers 42 and 43 are combined in a square shape in a side view (front view in FIG. 9).

すなわち、上側の熱交換器４２を上部熱交換部、下側の熱交換器４３を下部熱交換部として、上部熱交換部４２の一端部４２ａと下部熱交換部４３の他端部４３ａを空気吹出口１０Ｂ側で所定の角度をもって突き合わせ、上部熱交換部４２の他端部４２ｂを熱交換器室４０の天板４０１に近づくように上向きに傾斜させ、下部熱交換部４３の他端部４３ｂをドレンパン４５に近づくように下向きに傾斜させている。   That is, the upper heat exchanger 42 is an upper heat exchange unit, the lower heat exchanger 43 is a lower heat exchange unit, and one end 42a of the upper heat exchange unit 42 and the other end 43a of the lower heat exchange unit 43 are air. The other end portion 42b of the upper heat exchanging portion 42 is tilted upward so as to approach the top plate 401 of the heat exchanger chamber 40, and the other end portion 43b of the lower heat exchanging portion 43 is abutted at a predetermined angle on the outlet 10B side. Is inclined downward so as to approach the drain pan 45.

上部熱交換部４２の一端部４２ａと下部熱交換部４３の一端部４３ａの突き合わせ部４１ａに隙間ができると、その隙間から熱交換されない空気が通過して熱交換効率が低下するおそれがある。   If there is a gap between the one end portion 42a of the upper heat exchanging portion 42 and the abutting portion 41a of the one end portion 43a of the lower heat exchanging portion 43, air that is not heat exchanged may pass through the gap and the heat exchange efficiency may be reduced.

そこで、特許文献１に記載された発明では、上部熱交換部４２と下部熱交換部４３の突き合わせ部４１ａに沿って帯状の遮風板を配置して、突き合わせ部４１ａから熱交換されない空気が通過しないようにしている。また、上部熱交換部４２の一端部４２ａと下部熱交換部４３の一端部４３ａ同士を隙間が生じないようにワイヤ等の連結具で連結するようにしている。   Therefore, in the invention described in Patent Document 1, a band-shaped wind shield is arranged along the abutting portion 41a of the upper heat exchanging portion 42 and the lower heat exchanging portion 43, and air that is not heat-exchanged passes through the abutting portion 41a. I try not to. Further, the one end portion 42a of the upper heat exchanging portion 42 and the one end portion 43a of the lower heat exchanging portion 43 are connected to each other by a connecting tool such as a wire so as not to generate a gap.

しかしながら、遮風板はその両端のみが熱交換器４１を支持する左側支持ブラケットと右側支持ブラケット（ともに図示しない）とに固定された状態であるため、例えば当該空気調和機の大型化に伴い送風機３１からの風速が増大すると、遮風板が振動しいわゆるビビリ音が発生することがある。   However, since only the both ends of the windshield plate are fixed to the left support bracket and the right support bracket (both not shown) that support the heat exchanger 41, for example, as the air conditioner increases in size, the blower When the wind speed from 31 increases, a windshield may vibrate and what is called a chatter noise may be generated.

次に、図１ないし図８により、本発明の実施形態について説明するが、本発明はこれに限定されるものではない。   Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 8, but the present invention is not limited to this.

まず、図１ないし図３および図５を参照して、この実施形態に係る空気調和機１Ａは、従来例として先の図９で説明したダクト型空気調和機１Ｂと同じく天井裏に設置される直方体状の筐体１０を備えている。   First, referring to FIG. 1 to FIG. 3 and FIG. 5, an air conditioner 1A according to this embodiment is installed behind the ceiling in the same manner as the duct type air conditioner 1B described in FIG. 9 as a conventional example. A rectangular parallelepiped casing 10 is provided.

筐体１０の対向する両面のうち、その一方の面側（図３，図５では右側）に空気吸込口１０Ａが設けられ、他方の面側（図３，図５では左側）に空気吹出口１０Ｂが設けられている。空気吸込口１０Ａは、図示しない吸込側ダクトを介して天井面に設けられている空気吸込グリルと接続され、空気吹出口１０Ｂは、同じく図示しない吹出側ダクトを介して天井面に設けられている空気吹出グリルと接続される。   An air suction port 10A is provided on one surface side (the right side in FIGS. 3 and 5) of the opposing surfaces of the housing 10, and an air outlet is provided on the other surface side (the left side in FIGS. 3 and 5). 10B is provided. 10A of air suction inlets are connected with the air suction grille provided in the ceiling surface via the suction side duct which is not shown in figure, and the air blower outlet 10B is similarly provided in the ceiling surface via the ventilation side duct which is not shown in figure. Connected with air blowing grille.

筐体１０の内部は、仕切り板２０によって、空気吸込口１０Ａ側の送風機室３０と、空気吹出口１０Ｂ側の熱交換器室４０とに区画されている。   The interior of the housing 10 is partitioned by a partition plate 20 into a blower chamber 30 on the air inlet 10A side and a heat exchanger chamber 40 on the air outlet 10B side.

送風機室３０内には、送風機としてシロッコファン３１が配置されている。シロッコファン３１は、多翼円筒体（多翼ファン）３３を有する遠心送風機の一種であり、多翼円筒体３３は、スクロールケーシング３２内に収納されている。   In the blower chamber 30, a sirocco fan 31 is disposed as a blower. The sirocco fan 31 is a kind of centrifugal blower having a multi-blade cylinder (multi-blade fan) 33, and the multi-blade cylinder 33 is accommodated in a scroll casing 32.

図３に示すように、スクロールケーシング３２の側面（この実施形態では両側面）に空気吸込口３２ａが設けられており、多翼円筒体３３の回転により、空気が空気吸込口３２ａから吸い込まれ、スクロールケーシング３２の送風口３２ｂから、熱交換器室４０に配置される熱交換器４１の一部分に向けて集中して吹き出される。   As shown in FIG. 3, air suction ports 32a are provided on the side surfaces (both side surfaces in this embodiment) of the scroll casing 32, and air is sucked from the air suction ports 32a by the rotation of the multiblade cylindrical body 33. From the blower opening 32 b of the scroll casing 32, the air is concentrated and blown toward a part of the heat exchanger 41 arranged in the heat exchanger chamber 40.

図３に示すように、この実施形態では、シロッコファン３１を２台としている。シロッコファン３１，３１は、多翼円筒体３３の回転軸が同一直線上に存在するように仕切り板２０に沿って並置され、その間に配置される両軸モータ３４により駆動される。   As shown in FIG. 3, in this embodiment, two sirocco fans 31 are provided. The sirocco fans 31, 31 are juxtaposed along the partition plate 20 so that the rotating shafts of the multiblade cylindrical body 33 are on the same straight line, and are driven by a biaxial motor 34 disposed therebetween.

仕切り板２０には、シロッコファン３１の送風口３２ｂが嵌合される送風窓２１（図５参照）が形成されている。この実施形態において、シロッコファン３１は２台であるから、これに対応して、送風窓２１も２箇所に設けられている。   The partition plate 20 is formed with an air blowing window 21 (see FIG. 5) into which the air blowing port 32b of the sirocco fan 31 is fitted. In this embodiment, since there are two sirocco fans 31, correspondingly, the blowing windows 21 are also provided at two locations.

熱交換器室４０内には、熱交換器４１とドレンパン４５とが収納されている。熱交換器室４０は上面に天板４０１を備え、ドレンパン４５は熱交換器室４０の天板４０１と対向する底部４０２に配置されている。   A heat exchanger 41 and a drain pan 45 are accommodated in the heat exchanger chamber 40. The heat exchanger chamber 40 is provided with a top plate 401 on the upper surface, and the drain pan 45 is disposed on the bottom 402 facing the top plate 401 of the heat exchanger chamber 40.

この実施形態においても、従来例として先の図９で説明したダクト型空気調和機１Ｂと同じく、熱交換器４１には、２つの平面状の熱交換器４２，４３を側面視でくの字状に組合せた熱交換器が用いられている。   Also in this embodiment, like the duct type air conditioner 1B described with reference to FIG. 9 as a conventional example, the heat exchanger 41 includes two planar heat exchangers 42 and 43 in a side view. Combined heat exchangers are used.

上側の熱交換器４２を上部熱交換部、下側の熱交換器４３を下部熱交換部、また、熱交換器室４０の底面と上面の高さ方向を上下方向として、上部熱交換部４２の一端部４２ａと下部熱交換部４３の一端部４３ａを空気吹出口１０Ｂ側で所定の角度をもって突き合わせ、上部熱交換部４２の他端部４２ｂを熱交換器室４０の天板４０１に近づくように上向きに傾斜させ、下部熱交換部４３の他端部４３ｂを熱交換器室４０の底部に配置されているドレンパン４５に近づくように下向きに傾斜させている。   The upper heat exchanger 42 is an upper heat exchange part, the lower heat exchanger 43 is a lower heat exchange part, and the height direction of the bottom surface and the upper surface of the heat exchanger chamber 40 is the vertical direction, and the upper heat exchange part 42 The one end portion 42a of the lower heat exchange portion 43 and the one end portion 43a of the lower heat exchange portion 43 are abutted at a predetermined angle on the air outlet 10B side, and the other end portion 42b of the upper heat exchange portion 42 is brought closer to the top plate 401 of the heat exchanger chamber 40. The other end portion 43b of the lower heat exchanging portion 43 is inclined downward so as to approach the drain pan 45 disposed at the bottom portion of the heat exchanger chamber 40.

図２を参照して、熱交換器４１は、その左右両端に支持ブラケット４６ａ，４６ｂを備え、支持ブラケット４６ａ，４６ｂに支持された状態で熱交換器室４０内に収納される。また、熱交換器４１は、その一端側に配管接続具４１０を備え、配管接続具４１０を介して図示しない室外機と接続される。   Referring to FIG. 2, heat exchanger 41 includes support brackets 46a and 46b at both left and right ends thereof, and is housed in heat exchanger chamber 40 while being supported by support brackets 46a and 46b. The heat exchanger 41 includes a pipe connector 410 on one end side thereof, and is connected to an outdoor unit (not shown) via the pipe connector 410.

例えば、搬送時の落下衝撃等により、上部熱交換部４２の一端部４２ａと下部熱交換部４３の一端部４３ａの突き合わせ部４１ａに隙間ができると、その隙間から熱交換されない空気が通過して熱交換効率が低下するおそれがある。   For example, when a gap is formed between the one end portion 42a of the upper heat exchanging portion 42 and the abutting portion 41a of the one end portion 43a of the lower heat exchanging portion 43 due to a drop impact during transportation, air that is not heat exchanged passes through the gap. The heat exchange efficiency may be reduced.

そこで、この実施形態においても、熱交換器４１の突き合わせ部４１ａに沿って熱交換されない空気の通過を阻止する遮風板５０が設けられるが、本発明において、遮風板５０は、送風やモータ３４による振動等によって振動しないように、遮風板５０自体に上部熱交換部４２と下部熱交換部４３とに固定するための固定手段を備えている。   Therefore, in this embodiment, a wind shield 50 that prevents passage of air that is not heat-exchanged is provided along the abutting portion 41a of the heat exchanger 41. In the present invention, the wind shield 50 is a fan or a motor. The wind shield 50 itself is provided with fixing means for fixing the upper heat exchanging portion 42 and the lower heat exchanging portion 43 so as not to vibrate due to vibrations caused by 34.

図４ないし図６を参照して、遮風板５０は、帯状の遮風板本体５１を備えている。遮風板本体５１は、熱交換器４１の突き合わせ部４１ａの一端から他端に至る長さ、すなわち、熱交換器４１の支持ブラケット４６ａ，４６ｂ間の距離に相当する長さを有し、その両端には、支持ブラケット４６ａ，４６ｂにネジ止め等により固定される固着片５３，５３が設けられている。この固着片５３，５３は、遮風板本体５１の端部をほぼ直角に折り曲げることにより形成されている。   With reference to FIGS. 4 to 6, the wind shield 50 includes a belt-like wind shield main body 51. The windshield body 51 has a length from one end to the other end of the butting portion 41a of the heat exchanger 41, that is, a length corresponding to the distance between the support brackets 46a and 46b of the heat exchanger 41, At both ends, fixing pieces 53, 53 fixed to the support brackets 46a, 46b by screws or the like are provided. The fixing pieces 53 are formed by bending the end portion of the wind shielding plate main body 51 substantially at a right angle.

上記したように、上部熱交換部４２の一端部４２ａと下部熱交換部４３の一端部４３ａは所定の角度をもって突き合わされていることから、遮風板本体５１は、その突き合わせ部４１ａの形状に合致するように、その突き合わせ角αにほぼ等しい角度を有する断面くの字状に形成されている。   As described above, since the one end portion 42a of the upper heat exchanging portion 42 and the one end portion 43a of the lower heat exchanging portion 43 are abutted at a predetermined angle, the windshield body 51 is formed in the shape of the abutting portion 41a. In order to match, the cross section is formed in a square shape having an angle substantially equal to the butt angle α.

遮風板本体５１には、上部熱交換部４２と下部熱交換部４３に対する固定手段５２が設けられている。固定手段５２には、遮風板本体５１の上縁５１ａから上部熱交換部４２の上面４２ｕに沿うように引き出された上部固定片５２１と、遮風板本体５１の下縁５１ｂから下部熱交換部４３の下面４３ｌに沿うように引き出された下部固定片５２２とが含まれている。   The windshield body 51 is provided with fixing means 52 for the upper heat exchanging portion 42 and the lower heat exchanging portion 43. The fixing means 52 includes an upper fixing piece 521 drawn from the upper edge 51 a of the windshield body 51 along the upper surface 42 u of the upper heat exchange section 42, and a lower heat exchange from the lower edge 51 b of the windshield body 51. The lower fixing piece 522 pulled out along the lower surface 43l of the part 43 is included.

なお、上部熱交換部４２の上面４２ｕは、上部熱交換部４２のうちの熱交換器室４０の天板４０１と向き合う側の面で、下部熱交換部４３の下面４３ｌは、熱交換器室４０のドレンパン４５が配置される底部と向き合う側の面である。   The upper surface 42u of the upper heat exchanging unit 42 is a surface of the upper heat exchanging unit 42 facing the top plate 401 of the heat exchanger chamber 40, and the lower surface 43l of the lower heat exchanging unit 43 is a heat exchanger chamber. It is a surface on the side facing the bottom where 40 drain pans 45 are arranged.

熱交換器４１は、複数枚のフィンが所定の間隔をもって配置されたフィン群Ｆと、上記フィン群Ｆを貫通する冷媒配管Ｐとを備え、上部固定片５２１と下部固定片５２２は、それぞれ、熱交換器４１の冷媒配管Ｐの一部に係止される係止爪５４を備えている。   The heat exchanger 41 includes a fin group F in which a plurality of fins are arranged at a predetermined interval, and a refrigerant pipe P that penetrates the fin group F. The upper fixed piece 521 and the lower fixed piece 522 are respectively A locking claw 54 that is locked to a part of the refrigerant pipe P of the heat exchanger 41 is provided.

上部固定片５２１と下部固定片５２２はともに矩形状で、この実施形態において、係止爪５４は、上部固定片５２１と下部固定片５２２の両側縁から熱交換器４１（４２，４３）側に向けて形成された係止鉤５４１からなる。この係止鉤５４１によれば、熱交換器４１のフィン間に入り込ませて冷媒配管Ｐに係止することができる。   The upper fixed piece 521 and the lower fixed piece 522 are both rectangular, and in this embodiment, the locking claw 54 extends from both side edges of the upper fixed piece 521 and the lower fixed piece 522 toward the heat exchanger 41 (42, 43). It consists of a locking rod 541 formed facing toward it. According to the locking rod 541, the heat exchanger 41 can be inserted between the fins and locked to the refrigerant pipe P.

遮風板５０を熱交換器４１の突き合わせ部４１ａに配置する際、上部固定片５２１の係止鉤５４１を上部熱交換部４２の冷媒配管Ｐに係止し、下部固定片５２２の係止鉤５４１を下部熱交換部４３の冷媒配管Ｐに係止することにより、遮風板５０を突き合わせ部４１ａに固定することができる。   When the wind shielding plate 50 is disposed at the abutting portion 41 a of the heat exchanger 41, the locking rod 541 of the upper fixing piece 521 is locked to the refrigerant pipe P of the upper heat exchanging portion 42 and the locking rod of the lower fixing piece 522 is locked. By locking 541 to the refrigerant pipe P of the lower heat exchanging portion 43, the wind shielding plate 50 can be fixed to the butting portion 41a.

また、遮風板５０の固定手段５２により、上部熱交換部４２の一端部４２ａと下部熱交換部４３の一端部４３ａ同士を外部衝撃（例えば、搬送時の落下衝撃）を受けたとしても開かないように連結することができる。   Further, the fixing means 52 of the wind shielding plate 50 opens the one end portion 42a of the upper heat exchanging portion 42 and the one end portion 43a of the lower heat exchanging portion 43 even if they are subjected to external impact (for example, drop impact during transportation). It can be connected so that there is no.

上記実施形態では、係止爪５４を上部固定片５２１と下部固定片５２２の側縁から熱交換器４１（４２，４３）側に向けて形成された係止鉤５４１としているが、別の実施形態として、図７に示すように、係止爪５４を上部固定片５２１と下部固定片５２２の各先端部分を熱交換器４１（４２，４３）側（内側）に向けて折曲げた爪片５４２としてもよい。   In the above embodiment, the locking claw 54 is the locking rod 541 formed from the side edges of the upper fixed piece 521 and the lower fixed piece 522 toward the heat exchanger 41 (42, 43) side. As a form, as shown in FIG. 7, the locking claw 54 is a claw piece that is bent with the tip portions of the upper fixing piece 521 and the lower fixing piece 522 facing the heat exchanger 41 (42, 43) side (inner side) It may be 542.

この爪片５４２によれば、図８に示すように、上部熱交換部４２と下部熱交換部４３の各フィンを押し潰して所定の冷媒配管Ｐに係止することになる。   According to the claw piece 542, as shown in FIG. 8, the fins of the upper heat exchanging portion 42 and the lower heat exchanging portion 43 are crushed and locked to a predetermined refrigerant pipe P.

爪片５４２は、予め折り曲げられた状態で冷媒配管Ｐに食いつくように熱交換部４２，４３に強制的に取り付けられてもよいが、上部固定片５２１を上部熱交換部４２の上面４２ｕに沿わせ、下部固定片５２２を下部熱交換部４３の下面４３ｌに沿わせたのち、その各先端部を冷媒配管Ｐに食いつくように内側に折り曲げて爪片５４２を形成してもよい。   The claw piece 542 may be forcibly attached to the heat exchanging parts 42 and 43 so as to bite into the refrigerant pipe P in a bent state in advance, but the upper fixing piece 521 is arranged along the upper surface 42u of the upper heat exchanging part 42. Then, after the lower fixing piece 522 is placed along the lower surface 431 of the lower heat exchanging portion 43, the claw piece 542 may be formed by bending each tip end inward so as to bite into the refrigerant pipe P.

ところで、熱交換器４１（４２，４３）にて生成された結露水の多くはドレンパン４５上に滴下するが、熱交換器４１の突き合わせ部４１ａ付近の結露水は、風速が速い箇所では、下部熱交換部４３の一端部４３ａを飛散開始点として飛散するため、熱交換器室４０の外部に漏出することがある。熱交換器４１の突き合わせ部４１ａのうち風速が速い箇所は、シロッコファン３１の送風口３２ｂと対向する箇所である。   By the way, although most of the dew condensation water produced | generated in the heat exchanger 41 (42, 43) is dripped on the drain pan 45, the dew condensation water near the butting | matching part 41a of the heat exchanger 41 is a lower part in the location where a wind speed is high. Since the one end portion 43a of the heat exchange unit 43 is scattered as the scattering start point, it may leak out of the heat exchanger chamber 40. The place where the wind speed is fast in the butting portion 41 a of the heat exchanger 41 is a place facing the air blowing port 32 b of the sirocco fan 31.

上記実施形態（図４の実施形態、図７の別の実施形態）に係る遮風板５０において、固定手段５２（上部固定片５２１と下部固定片５２２）は、シロッコファン３１，３１の送風口３２ｂ，３２ｂと対向する風速が速い箇所に配置されている。これによれば、遮風板５０の送風による振動が確実に防止される。   In the wind shield 50 according to the above embodiment (the embodiment of FIG. 4 and another embodiment of FIG. 7), the fixing means 52 (the upper fixing piece 521 and the lower fixing piece 522) are the air outlets of the sirocco fans 31 and 31. It arrange | positions in the location where the wind speed which opposes 32b and 32b is quick. According to this, the vibration by the ventilation of the windshield 50 is reliably prevented.

また、突き合わせ部４１ａのうちの固定手段５２で覆われる箇所に存在する結露水は、下部固定片５２２の内面をつたわって下部固定片５２２の先端部（下端部）を滴下点として空気吹出口１０Ｂ側に向けて飛散することになり、その滴下点が突き合わせ部４１ａの先端部よりも後方（熱交換器室の内側）となるため、下部固定片５２２の先端部から滴下する結露水のほとんどがドレンパン４５に回収されることになる。   Further, the dew condensation water present at the location covered by the fixing means 52 in the abutting portion 41a is connected to the inner surface of the lower fixing piece 522, and the tip (lower end) of the lower fixing piece 522 is used as the dripping point. Since the dripping point is behind the tip of the butting portion 41a (inside the heat exchanger chamber), most of the condensed water dripping from the tip of the lower fixed piece 522 is scattered. It will be collected in the drain pan 45.

このようにして、固定手段５２のうちの特に下部固定片５２２は露飛びを抑止する。なお、固定手段５２は、風速が速い箇所のみでなく、遮風板５０の全長にわたって設けられてもよい。また、遮風板５０は合成樹脂製、金属製（板金製）のいずれであってもよい。   In this way, especially the lower fixing piece 522 of the fixing means 52 suppresses exposure. The fixing means 52 may be provided not only at a location where the wind speed is high, but also over the entire length of the wind shield plate 50. Further, the wind shielding plate 50 may be made of synthetic resin or metal (made of sheet metal).

以上説明したように、本発明によれば、遮風板５０自体に上部熱交換部４２と下部熱交換部４３とに対する固定手段５０を設けたことにより、遮風板５０を熱交換部４１の突き合わせ部４１ａに固定するための固定部材が不要で、遮風板５０の送風による振動や、モータ３４による振動等が防止される。   As described above, according to the present invention, the wind shield plate 50 is attached to the upper heat exchange section 42 and the lower heat exchange section 43 by the wind shield board 50 itself. A fixing member for fixing to the abutting portion 41a is unnecessary, and vibration due to blowing of the wind shielding plate 50, vibration due to the motor 34, and the like are prevented.

また、遮風板５０の固定手段５２により、例えば搬送時等の衝撃により上部熱交換部４２と下部熱交換部４３の突き合わせ部４１ａが開かないようにすることができる。   Further, the fixing means 52 of the wind shielding plate 50 can prevent the abutting portion 41a of the upper heat exchanging portion 42 and the lower heat exchanging portion 43 from being opened due to, for example, an impact during transportation.
