Description

本発明は、ユニット本体に対する室内熱交換器および送風機との取付け構造を改良した空気調和機の室内ユニットに関する。   The present invention relates to an indoor unit of an air conditioner having an improved structure for attaching an indoor heat exchanger and a blower to a unit body.

室内ユニットと室外ユニットとから構成される空気調和機が多用されている。室内ユニットにおいては、吸込み口および吹出し口を備え前面パネルと後本体とを組合せてなるユニット本体が構成される。このユニット本体内に熱交換器と送風機とが対向して配置される。
上記熱交換器として、近時、［特許文献１］に示されるように、略逆Ｖ字状に形成される熱交換器が多用される傾向にある。これは、側面視が湾曲成された前側熱交換器部と、直状で斜めに傾斜する後側熱交換器部との組合せからなる。この種の熱交換器であれば、単なる平板状の熱交換器と比較して熱交換面積が飛躍的に増大し、かつ多段に折り曲げた熱交換器よりも成型加工が簡単ですむ。 An air conditioner composed of an indoor unit and an outdoor unit is often used. In the indoor unit, a unit main body that includes a suction port and a blowout port and is configured by combining a front panel and a rear main body is configured. A heat exchanger and a blower are disposed opposite to each other in the unit body.
Recently, as the heat exchanger, as shown in [Patent Document 1], a heat exchanger formed in a substantially inverted V shape tends to be frequently used. This consists of a combination of a front heat exchanger section curved in side view and a rear heat exchanger section that is straight and slanted. This type of heat exchanger dramatically increases the heat exchange area compared to a simple flat plate heat exchanger, and is easier to mold than a heat exchanger bent in multiple stages.

そして、室内熱交換器は前側熱交換器部と後側熱交換器部で主熱交換器を構成し、さらに第１の補助熱交換器部と第２の補助熱交換器部とからなる補助熱交換器を備えている。この補助熱交換器は主熱交換器を略逆Ｖ字状に形成することによって生じるデッドスペースを利用して備えられ、ユニット本体の容量をそのまま維持して据付けスペースに影響を及ぼさずに熱交換器の熱交換容量を増加させ、熱交換能力の増大が得られる。
上記送風機は、主熱交換器に正対して配置される横流ファンと、この横流ファンを回転駆動するファンモータとで構成され、前側熱交換器部と後側熱交換器部との間に配置される。すなわち、前後側熱交換器部で送風機を傘状に覆うことにより、ユニット本体内のスペースを有効に使え、本体をより小形化できる。
特開２００３−７４８９０号公報 And an indoor heat exchanger comprises a main heat exchanger by the front side heat exchanger part and the rear side heat exchanger part, and also the auxiliary | assistant which consists of a 1st auxiliary heat exchanger part and a 2nd auxiliary heat exchanger part It has a heat exchanger. This auxiliary heat exchanger is provided by utilizing the dead space generated by forming the main heat exchanger in a substantially inverted V shape, exchanging heat without affecting the installation space while maintaining the capacity of the unit body. The heat exchange capacity of the vessel is increased, and an increase in heat exchange capacity is obtained.
The blower is composed of a cross-flow fan arranged to face the main heat exchanger and a fan motor that rotationally drives the cross-flow fan, and is arranged between the front heat exchanger section and the rear heat exchanger section. Is done. That is, by covering the blower in an umbrella shape with the front and rear heat exchanger sections, the space in the unit main body can be used effectively, and the main body can be further miniaturized.
Japanese Patent Laid-Open No. 2003-74890

ここで新たな問題の一つとして、室内熱交換器を構成する主熱交換器と補助熱交換器のユニット本体に対する取付け固定構造がある。上述の［特許文献１］では、室内熱交換器の両側部を抑え固定金具を用いて固定している。この抑え固定金具は、前後側熱交換器部の上端を間にして、第１補助熱交換器部の一部上面と第２の補助熱交換器部上面を抑える抑え部と、この抑え部の両端に形成される取付け部とからなる金属板体である。
上述の抑え金具は、室内熱交換器全体の外側を覆うように折曲形成されていて、大型化した部品とならざるを得ない。そのため、この抑え金具を覆う部材である前面パネルがさらに手前側に突出して圧迫感を増してしまい、前面パネルの設計自由度が規制されるという不具合がある。 Here, as one of the new problems, there is a structure for fixing the main heat exchanger and auxiliary heat exchanger constituting the indoor heat exchanger to the unit main body. In the above-mentioned [Patent Document 1], both side portions of the indoor heat exchanger are suppressed and fixed using fixing brackets. The holding fixture includes a holding portion for holding the upper surface of the first auxiliary heat exchanger portion and the upper surface of the second auxiliary heat exchanger portion with the upper ends of the front and rear heat exchanger portions therebetween, It is the metal plate body which consists of the attachment part formed in both ends.
The above-described holding metal fitting is bent so as to cover the outside of the entire indoor heat exchanger, and must be a large-sized component. For this reason, the front panel, which is a member covering the holding bracket, further protrudes toward the near side, increasing the feeling of pressure, and there is a problem that the degree of freedom in designing the front panel is restricted.

また、特に冷房運転時には室内熱交換器の熱交換作用にともなって空気中の水分を凝縮し、その凝縮された水分であるドレンが室内熱交換器に付着する。時間の経過とともに肥大化してやがては滴下するドレン水となる。そこで、前側熱交換器部と後側熱交換器部のそれぞれ下部にドレンパンが配置され、ドレン水を受ける。
しかしながら、前後側熱交換器部は多数枚のフィンが狭小の間隙を存して並設され、これらフィンの左右両側端に設けられる端板から熱交換パイプの蛇行状曲成部であるＵベンドが突出する構成である。そして、前後側熱交換器部の側端部には、互いの熱交換器部を連通するジャンピングパイプや室外ユニットへ延出する補助配管が位置する。 In particular, during the cooling operation, moisture in the air is condensed with the heat exchange action of the indoor heat exchanger, and the condensed moisture drain adheres to the indoor heat exchanger. Over time, it becomes enlarged and eventually becomes drained dripping water. Therefore, a drain pan is disposed at the lower part of each of the front heat exchanger part and the rear heat exchanger part to receive drain water.
However, the front and rear heat exchanger sections have a large number of fins arranged side by side with a narrow gap, and U-bends that are serpentine bent portions of heat exchange pipes from the end plates provided on the left and right ends of these fins. It is the structure which protrudes. A jumping pipe that communicates with each other and an auxiliary pipe that extends to the outdoor unit are located at the side ends of the front and rear heat exchanger sections.

当然、これらＵベンド、ジャンピングパイプおよび補助配管にも冷媒が導通するので、熱交換作用にともなってドレン水が付着して滴下することがある。室内ユニットの構成上、室内熱交換器側端部の下方部位には、送風機を構成するファンモータが配置されていて、そのままでは滴下するドレン水でファンモータが濡れてしまう。
上述の［特許文献１］では、特にファンモータをドレン水から守ることの構成の記載はないが、通常、上記ファンモータが滴下するドレン水で濡れないようにファンモータカバーが取付けられていて、電気事故が発生する虞れはない。すなわち、ファンモータカバーは一種のドレンパンとして用いられているだけであって、ユニット本体に対して剛性向上を得る有効利用の考えはない。 Naturally, since the refrigerant also conducts to these U bends, jumping pipes, and auxiliary pipes, drain water may adhere and drip with the heat exchange action. The fan motor which comprises a blower is arrange | positioned in the site | part below the indoor heat exchanger side edge part on the structure of an indoor unit, and a fan motor will get wet with the drain water dripped as it is.
In the above-mentioned [Patent Document 1], there is no description of the configuration for protecting the fan motor from drain water in particular, but usually the fan motor cover is attached so as not to get wet with the drain water dripped by the fan motor. There is no risk of electrical accidents. That is, the fan motor cover is only used as a kind of drain pan, and there is no idea of effective use for improving the rigidity of the unit body.

本発明は上記事情に着目してなされたものであり、その目的とするところは、主熱交換器と補助熱交換器とから構成される室内熱交換器の支持構造を小型簡素化して前面パネルに対する設計自由度の向上化を図るとともに、後本体に対する剛性向上化を得られる空気調和機の室内ユニットを提供しようとするものである。   The present invention has been made by paying attention to the above circumstances, and the object of the present invention is to reduce the size and simplification of the support structure for the indoor heat exchanger composed of the main heat exchanger and the auxiliary heat exchanger. It is intended to provide an indoor unit of an air conditioner that can improve the degree of design freedom with respect to the rear body and that can improve the rigidity of the rear body.

熱交換器固定部材として、切欠き部近傍に取付け具を介して取付け固定される取付け部および室内熱交換器を構成する主熱交換器に対して補助熱交換器を抱持固定する抱持部を有し、
ファンモータカバーとして、後本体におけるファンモータ上面に設置され、左右の後部に後板部の切欠き部左右近傍部に取付け具を介して取付け固定される取付け部を有し、上面が室内熱交換器の側部に突出するＵベンドや上記補助配管等を配設し、かつこれらＵベンド等から滴下するドレン水を受ける受け部を有し、上記ファンモータをカバーする。 In order to satisfy the above object, in the present invention, the unit body is provided with a suction port and a blowout port, and the front panel and the rear body are combined. The indoor heat exchanger is disposed on the rear body in the unit body, A main heat exchanger formed in a substantially inverted V shape in a side view and a part of the main heat exchanger surface by a front heat exchanger part located on the front side of the rear side and a rear heat exchanger part located on the back side A cross-flow fan and a fan motor arranged so as to be covered between the front heat exchanger part and the rear heat exchanger part in the indoor heat exchanger as a blower. The rear body has a rear plate portion constituting the rear surface, and a fan motor arrangement portion of the rear plate which opens downward from the upper edge and cuts through the auxiliary piping extending from the indoor heat exchanger to the outdoor unit side. A notch is provided ,

1 is a schematic longitudinal sectional view of an indoor unit constituting an air conditioner, FIG. 2 is a schematic front view of the indoor unit with the front panel 2 and the like removed, and FIG. 3 is a front panel 2 and the indoor heat exchanger 10 and others removed. It is a schematic perspective view of an indoor unit.
The unit main body 1 includes a front panel 2 and a rear main body 3, and has a horizontally long shape in which the width direction is extremely long with respect to the vertical direction. The front panel 2 is curved and protrudes to the near side, and has side portions on both the left and right sides. The rear main body 3 has a horizontally long rectangular shape and is attached to the indoor wall surface. A front suction port 4 is opened at a part of the front side of the front panel 2, and a movable panel 5 supported by an opening / closing drive mechanism (not shown) is fitted therein. When the operation is stopped, the movable panel 5 is flush with the front panel 2 and closes the front suction port 4. However, when the operation is performed, the upper end protrudes and moves forward as indicated by the two-dot chain line in the figure. Control is performed to open the part suction port 4.

前面パネル２の上部に亘って、枠状の桟７が嵌め込まれる上部吸込み口６が設けられる。前面パネル２の下部には、運転条件に応じて姿勢角度を可変し熱交換空気の吹出し方向を設定する、もしくは完全閉成する２枚の水平ルーバ８ａ，８ｂおよびこれら水平ルーバ８ａ，８ｂの奥側に縦ルーバ８ｃを備えた吹出し口９が設けられる。
ユニット本体１内には、後述する室内熱交換器１０が配置されていて、前部吸込み口４と上部吸込み口６に対向して配置される。室内熱交換器１０と前面パネル２との間にはフィルタ１１が挿脱自在に取付けられる。このフィルタ１１は上記前面パネル２裏面側に形成された図示しないフィルタガイドに沿って案内されるようになっている。 An upper suction port 6 into which a frame-like bar 7 is fitted is provided over the upper portion of the front panel 2. Below the front panel 2 are two horizontal louvers 8a, 8b that change the posture angle and set the direction of blowing out the heat exchange air according to the operating conditions, or are completely closed, and the back of these horizontal louvers 8a, 8b. A blowout port 9 having a vertical louver 8c is provided on the side.
An indoor heat exchanger 10 to be described later is disposed in the unit main body 1 and is disposed to face the front suction port 4 and the upper suction port 6. A filter 11 is detachably attached between the indoor heat exchanger 10 and the front panel 2. The filter 11 is guided along a filter guide (not shown) formed on the back side of the front panel 2.

つぎに、上記室内熱交換器１０について説明する。この室内熱交換器１０は前側熱交換器部１０Ａと後側熱交換器部１０Ｂとで略逆Ｖ字状に形成される主熱交換器１００Ａを備えている。上記前側熱交換器部１０Ａは、前面パネル２と間隙を存してほぼ平行な湾曲状に形成され、かつ後側熱交換器部１０Ｂは直状に形成されて上部吸込み口６と斜めに傾斜して対向する。上記前側熱交換器部１０Ａは、前部吸込み口４の全部および上部吸込み口６の一部に対向して配置され、後側熱交換器部１０Ｂは上部吸込み口６の残り一部に対向して配置される。
また、主熱交換器１００Ａを構成する前側熱交換器部１０Ａの前面上部および後側熱交換器部１０Ｂの上面に沿って、それぞれ補助熱交換器部１０Ｃが設けられ、前側熱交換器部１０Ａの前面下部に沿って過冷却用補助熱交換器部１０Ｄが設けられる。これら補助熱交換器部１０Ｃと過冷却用補助熱交換器部１０Ｄとで補助熱交換器１００Ｂが構成される。すなわち室内熱交換器１０は、主熱交換器１００Ａと補助熱交換器１００Ｂとの組合せてなるものである。 Next, the indoor heat exchanger 10 will be described. This indoor heat exchanger 10 includes a main heat exchanger 100A formed in a substantially inverted V shape by a front heat exchanger portion 10A and a rear heat exchanger portion 10B. The front heat exchanger portion 10A is formed in a substantially parallel curved shape with a gap with the front panel 2, and the rear heat exchanger portion 10B is formed in a straight shape and inclined obliquely with the upper suction port 6 Then face each other. The front heat exchanger section 10 </ b> A is disposed so as to face the entire front suction port 4 and a part of the upper suction port 6, and the rear heat exchanger section 10 </ b> B faces the remaining part of the upper suction port 6. Arranged.
Auxiliary heat exchanger portions 10C are provided along the upper front surface of the front heat exchanger portion 10A and the upper surface of the rear heat exchanger portion 10B constituting the main heat exchanger 100A, respectively, and the front heat exchanger portion 10A. A sub-cooling auxiliary heat exchanger section 10D is provided along the lower part of the front surface. These auxiliary heat exchanger units 10C and the subcooling auxiliary heat exchanger unit 10D constitute an auxiliary heat exchanger 100B. That is, the indoor heat exchanger 10 is a combination of the main heat exchanger 100A and the auxiliary heat exchanger 100B.

上記前側熱交換器部１０Ａ前面の補助熱交換器部１０Ｃと過冷却用補助熱交換器部１０Ｄの相互間には、空気清浄機１３が着脱自在に取付けられている。この空気清浄機１３は、電気集塵機と防臭フィルタとを並設してなるものである。特に、電気集塵機は流通する空気中の塵埃に電荷を与える荷電側電極と、電荷を与えられた塵埃を引きつけて捕捉する集塵側電極とから構成される。
そして、電気集塵機は通常の集塵時よりも集塵側電極との電位差が大きくなるように荷電側電極に高い高電圧を印加すると、多くのオゾンが発生するオゾン発生装置となる。このとき、周囲の空気の流れを制限するため送風機１４を停止もしくは極く低速運転することで、オゾンの発生量がより大となる。 An air cleaner 13 is detachably attached between the auxiliary heat exchanger section 10C on the front surface of the front heat exchanger section 10A and the auxiliary heat exchanger section 10D for supercooling. This air cleaner 13 is formed by arranging an electric dust collector and a deodorizing filter in parallel. In particular, the electrostatic precipitator is composed of a charge-side electrode that applies charge to the dust in the air that circulates, and a dust-collection side electrode that attracts and captures the charged dust.
The electric dust collector becomes an ozone generator that generates a large amount of ozone when a high voltage is applied to the charge side electrode so that the potential difference with the dust side electrode becomes larger than that during normal dust collection. At this time, the amount of ozone generated becomes larger by stopping the blower 14 or operating at a very low speed in order to limit the flow of ambient air.

上記室内熱交換器１０を構成する主熱交換器１００Ａである前側熱交換器部１０Ａと後側熱交換器部１０Ｂとの相互間であり、前後側熱交換器部１０Ａ，１０Ｂで覆われる位置に送風機１４が配置される。この送風機１４は、ファンモータ１４Ｍと、このファンモータ１４Ｍの回転軸に嵌着される横流ファン１４Ｆとから構成されている。上記横流ファン１４Ｆは、その軸方向長さが主熱交換器１００Ａの幅方向長さと略一致し、かつ正対するように配置される。
なお説明すると、主熱交換器１００Ａおよび補助熱交換器１００Ｂとも、多数枚のフィンＦを狭小の間隙を存して並設し、これらフィンＦの左右両側端には板厚の厚い端板Ｔが設けられる。そして、これら端板Ｔと全てのフィンＦに複数本の熱交換パイプＰが所定間隔を存して貫通して設けられる。端板Ｔから突出する熱交換パイプＰの端部で、隣接する部位相互にＵベンドＢが嵌め込まれ、かつロー付けなどの手段で密に連結固定される。したがって、熱交換パイプＰとＵベンドＢで１つの冷媒流路が構成される。 Position between the front side heat exchanger part 10A and the rear side heat exchanger part 10B which are the main heat exchangers 100A constituting the indoor heat exchanger 10 and covered with the front and rear side heat exchanger parts 10A and 10B An air blower 14 is disposed on the side. The blower 14 includes a fan motor 14M and a cross-flow fan 14F that is fitted to the rotation shaft of the fan motor 14M. The cross-flow fan 14F is disposed such that its axial length is substantially the same as the length of the main heat exchanger 100A in the width direction and is directly opposed.
In other words, in both the main heat exchanger 100A and the auxiliary heat exchanger 100B, a large number of fins F are juxtaposed with a narrow gap therebetween, and thick end plates T on the left and right sides of these fins F are arranged. Is provided. A plurality of heat exchange pipes P are provided through the end plates T and all the fins F at predetermined intervals. At the end of the heat exchange pipe P protruding from the end plate T, the U bend B is fitted between adjacent parts, and is closely connected and fixed by means such as brazing. Therefore, one refrigerant flow path is constituted by the heat exchange pipe P and the U bend B.

すなわち、主熱交換器１００Ａおよび補助熱交換器１００Ｂともに、端板Ｔから熱交換パイプＰの蛇行状曲成部であるＵベンドＢが突出する。そして、これら主、補助熱交換器１０Ａ，１００Ｂ側部に、前後側熱交換器部１０Ａ，１０Ｂ相互もしくは補助熱交換器部相互１０Ｂ〜１０Ｄを連通するためのジャンピングパイプ（図示しない）や、室内熱交換器１０から室外ユニットへ延出する補助配管Ｈ（後述する図１０、図１１に示している）が位置する。
このような室内熱交換器１０に対して上記送風機１４を構成する横流ファン１４Ｆは、フィンＦおよび両側端板Ｔに亘る長さ寸法と同一の軸方向寸法をなして正対する。したがって、横流ファン１４Ｆを駆動するファンモータ１４Ｍは一方の端板Ｔから側部へ突出するＵベンドＢと、ジャンピングパイプおよび補助配管Ｈの直下方部位に位置することになる。 That is, the U bend B that is a meandering bent portion of the heat exchange pipe P protrudes from the end plate T in both the main heat exchanger 100A and the auxiliary heat exchanger 100B. Further, a jumping pipe (not shown) for communicating the front and rear heat exchanger units 10A and 10B or the auxiliary heat exchanger units 10B to 10D to the side portions of the main and auxiliary heat exchangers 10A and 100B, An auxiliary pipe H (shown in FIGS. 10 and 11 to be described later) extending from the heat exchanger 10 to the outdoor unit is located.
The cross flow fan 14F constituting the blower 14 is opposed to the indoor heat exchanger 10 with the same axial dimension as the length across the fins F and the side end plates T. Accordingly, the fan motor 14M for driving the cross flow fan 14F is located at a position just below the U bend B protruding from one end plate T and the jumping pipe and the auxiliary pipe H.

一方、上記後本体３は、上記後側熱交換器部１０Ｂおよび補助熱交換器部１０Ｃの下端部傾斜に略一致する傾きをなし、これら下端部を囲むようにして後ドレンパン１５を備えている。
そして後本体３には、後ドレンパン１５から送風機１４の背面側に沿って曲成され、吹出し口９に至る後側送風路壁１６Ａが形成される。さらに後本体３は、前側熱交換器部１０Ａと過冷却用補助熱交換器部１０Ｄの下端部に略一致する傾きをなし、これら下端部を囲むようにして前ドレンパン１７を備えている。
上記前側熱交換器部１０Ａの下端部は前ドレンパン１７上に載り、後側熱交換器部１０Ｂの下端部は後ドレンパン１５上に載って、それぞれの熱交換器部１０Ａ，１０Ｂから滴下するドレン水を受け、図示しない排水ホースを介して外部に排水できるようになっている。
後本体３における前ドレンパン１７の送風機１４前面側にノーズ１８が設けられ、ノーズ１８から吹出し口９に至る前側送風路壁１６Ｂが形成される。この前側送風路壁１６Ｂと上記後側送風路壁１６Ａとで、上記送風機１４から吹出し口９に連通する送風路１６が形成される。 On the other hand, the rear main body 3 has an inclination substantially coincident with the inclination of the lower end portions of the rear heat exchanger section 10B and the auxiliary heat exchanger section 10C, and includes a rear drain pan 15 so as to surround these lower end sections.
The rear main body 3 is formed with a rear air passage wall 16 </ b> A that is bent along the back side of the blower 14 from the rear drain pan 15 and reaches the outlet 9. Further, the rear main body 3 has an inclination substantially coincident with the lower end portions of the front heat exchanger portion 10A and the subcooling auxiliary heat exchanger portion 10D, and includes a front drain pan 17 so as to surround these lower end portions.
The lower end portion of the front heat exchanger portion 10A is placed on the front drain pan 17, and the lower end portion of the rear heat exchanger portion 10B is placed on the rear drain pan 15 and is dripped from the respective heat exchanger portions 10A and 10B. It receives water and can drain to the outside through a drain hose (not shown).
A nose 18 is provided on the front side of the blower 14 of the front drain pan 17 in the rear main body 3, and a front air passage wall 16 </ b> B extending from the nose 18 to the outlet 9 is formed. The front air passage wall 16 </ b> B and the rear air passage wall 16 </ b> A form an air passage 16 that communicates from the blower 14 to the outlet 9.

上記後本体３で、かつ送風機１４を構成するファンモータ１４Ｍの背面側部位に対向する後板部３ａ上部には、上端部が開口しその上端縁から所定深さで切欠される切欠き部１９が設けられる。
この切欠き部１９には、上述した室内熱交換器１０から室外ユニットへ延出する補助配管Ｈ（図１０および図１１に示している）を挿通させるために設けられる。すなわち、切欠き部１９を設けずに後本体３の上端縁を乗り越える状態で補助配管Ｈを延出させると、ユニット本体１上面部から補助配管Ｈが上方へ突出することになり、ユニット本体１と天井面との間に余分なスペースが必要となってしまう。
上記送風機ファンモータ１４Ｍの側部で、かつ後本体３の上記切欠き部１９から側板部に亘る空間スペースには、電気部品組立２０が配置されている。この電気部品組立２０は、背面側に各種の制御用電気部品を収納する電気部品箱が配置され、この電気部品箱の前面に各種の表示灯を備えた表示ユニットが取付けられてなる。 In the rear main body 3 and on the upper part of the rear plate portion 3a facing the rear side portion of the fan motor 14M constituting the blower 14, a notch portion 19 is opened at an upper end portion and is notched at a predetermined depth from the upper end edge. Is provided.
The notch 19 is provided to allow the auxiliary pipe H (shown in FIGS. 10 and 11) extending from the indoor heat exchanger 10 to the outdoor unit to be inserted. That is, if the auxiliary pipe H is extended in a state where the upper end edge of the rear main body 3 is overcome without providing the notch portion 19, the auxiliary pipe H protrudes upward from the upper surface portion of the unit main body 1. And an extra space between the ceiling and the ceiling.
An electrical component assembly 20 is disposed in a side space of the blower fan motor 14M and in a space space from the notch portion 19 to the side plate portion of the rear main body 3. The electrical component assembly 20 includes an electrical component box that houses various control electrical components on the back side, and a display unit having various indicator lights attached to the front of the electrical component box.

このようにして構成される空気調和機の室内ユニットであり、リモコンの運転スイッチをオンに切換えると、前面パネル２に設けられる開閉駆動機構が作動して、可動パネル５が下端を枢支部として上端部が手前側に回動され、前部吸込み口４が開放される。同時に送風機１４が駆動されるとともに、冷凍サイクル運転が開始される。室内空気は、上部吸込み口６と前部吸込み口４からユニット本体１内に導かれ、エアーフィルタ１１を通過して室内空気に含まれる塵埃が捕捉される。
さらに、上記空気清浄機１３が作用して、エアーフィルタ１１で捕捉されなかった微細な塵埃を完全に捕捉し、かつ防臭機能を得る。したがって、清浄化した空気が熱交換器９に導かれ、主熱交換器１００Ａと補助熱交換器１００Ｂを通過して熱交換作用が行われる。熱交換した空気は、送風路１６に沿って導かれ、吹出し口９から縦ルーバ８ｃと水平ルーバ８ａ，８ｂに案内されて室内へ吹出され、効率のよい空気調和運転がなされる。
空調運転を終了させるためリモコンの運転スイッチをオフにすると、圧縮機と送風機１４および空気清浄機１３の運転が停止し、かつ開閉駆動機構は可動パネル５を回動変位させて前部吸込み口４を閉成する。 The indoor unit of the air conditioner constructed as described above, and when the operation switch of the remote control is turned on, the opening / closing drive mechanism provided on the front panel 2 is activated, and the movable panel 5 is the upper end with the lower end as a pivot. The part is rotated to the near side, and the front suction port 4 is opened. At the same time, the blower 14 is driven and the refrigeration cycle operation is started. The room air is guided into the unit body 1 from the upper suction port 6 and the front suction port 4, passes through the air filter 11, and dust contained in the room air is captured.
Further, the air cleaner 13 acts to completely capture fine dust that has not been captured by the air filter 11 and to obtain a deodorizing function. Therefore, the cleaned air is guided to the heat exchanger 9 and passes through the main heat exchanger 100A and the auxiliary heat exchanger 100B to perform a heat exchange action. The heat-exchanged air is guided along the air blowing path 16 and is guided from the blow-out port 9 to the vertical louvers 8c and the horizontal louvers 8a and 8b to be blown into the room, so that an efficient air-conditioning operation is performed.
When the operation switch of the remote control is turned off to end the air-conditioning operation, the operation of the compressor, the blower 14 and the air cleaner 13 is stopped, and the opening / closing drive mechanism rotationally displaces the movable panel 5 to move the front suction port 4. Is closed.

つぎに、後本体３の構成と、この後本体３に対する室内熱交換器１０および送風機１４の取付け構造について詳述する。
図４は後本体３を分解し、かつ後本体３に対する取付けられる構成部品を分解して示す図である。図１および図４に示すように、後本体３は、後板部３ａと上記後ドレンパン１５と後側送風路壁１６Ａ上側部分を一体に備えた上後本体部５Ａと、上記前ドレンパン１７と前側送風路壁１６Ｂと後側送風路壁１６Ａ下側部分を一体に備えた下後本体部５Ｂとの分割体である。 Next, the configuration of the rear main body 3 and the mounting structure of the indoor heat exchanger 10 and the blower 14 to the rear main body 3 will be described in detail.
FIG. 4 is an exploded view of the rear main body 3 and the components attached to the rear main body 3 in an exploded manner. As shown in FIGS. 1 and 4, the rear main body 3 includes a rear plate portion 3 a, the rear drain pan 15, an upper rear main body portion 5 </ b> A integrally including an upper portion of the rear air passage wall 16 </ b> A, and the front drain pan 17. This is a divided body of the lower rear body portion 5B integrally provided with the lower portion of the front air passage wall 16B and the rear air passage wall 16A.

そして、上後本体部５Ａの後側送風路壁１６Ａ辺部には左右に一対の係合用突起片ａが突設され、これら係合用突起辺ａと対向する下後本体部５Ｂの後側送風路壁１６Ａ辺部には一対の係合用嵌合凹部ｂが形成されている。上記上後本体部５Ａと下後本体部５Ｂを結合する際、これらの係合部ａと嵌合凹部ｂを重ね合せて係合することで、連続した後側送風路壁１６Ａが構成できる。
上後本体部５Ａの両側部には、前ドレンパン１７と後ドレンパン１５とを連通する案内樋部２２Ａ，２２Ｂが設けられていて、後ドレンパン１５で受けたドレン水を上記案内樋部２２Ａ，２２Ｂを介して前ドレンパン１７に導ける。図中右側の案内樋部２２Ａ上端縁が略半円状に形成される半円部で、上記送風機１４を構成するファンモータ１４Ｍの回転軸を受ける。すなわち、右側案内樋部２２Ａの右側空間に上記ファンモータ１４Ｍが配置され、横流ファン１４Ｆは左右の案内樋部２２Ａ，２２Ｂと前後ドレンパン１７，１５に囲れる。 Then, a pair of engaging protrusions a project from the left and right sides of the rear air passage wall 16A of the upper rear main body 5A, and the rear air flow of the lower rear main body 5B facing the engaging protrusions a. A pair of engagement fitting recesses b are formed on the side of the road wall 16A. When the upper rear main body portion 5A and the lower rear main body portion 5B are coupled, the engaging rear portion a and the fitting concave portion b are overlapped and engaged to form a continuous rear air passage wall 16A.
On both sides of the upper rear body portion 5A, guide rod portions 22A and 22B are provided for communicating the front drain pan 17 and the rear drain pan 15, and drain water received by the rear drain pan 15 is received by the guide rod portions 22A and 22B.

The upper end edge of the guide rod portion 22A on the right side in the drawing is a semicircular portion formed in a substantially semicircular shape, and receives the rotation shaft of the fan motor 14M constituting the blower 14. That is, the fan motor 14M is disposed in the right space of the right guide rod portion 22A, and the cross-flow fan 14F is surrounded by the left and right guide rod portions 22A and 22B and the front and rear drain pans 17 and 15.

実際には、上記ファンモータ１４Ｍには予めファンモータバンド２５が取付けられていて、このファンモータバンド２５の径方向に突出する取付け座２５ａ，２５ｂが取付けねじを介して後本体部３に取付けられることにより、上記ファンモータ１４Ｍの位置が定まり、かつ配置される。さらに、ファンモータ１４Ｍを取付けたファンモータバンド２５の上から後述するファンモータカバー３０が取付けられ、そのあと室内熱交換器１０が取付けられる。
また、図中左側の案内樋部２２Ｂのさらに左側の空間スペースに換気ユニットＫが取付けられている。この換気ユニットＫは、上記横流ファン１４Ｆの一方の支軸を受ける軸受け部を有するとともに、図示しないダンパと、ダンパ駆動機構および送風機構を備えている。そして、切換信号に応じてダンパが切換制御され、室内空気をユニット本体１内部に導通させてユニット本体１と構成部品を乾燥したり、室内空気を外部に排出するいわゆる換気扇機能を有する。 Actually, a fan motor band 25 is attached to the fan motor 14M in advance, and attachment seats 25a and 25b protruding in the radial direction of the fan motor band 25 are attached to the rear main body 3 via attachment screws. As a result, the position of the fan motor 14M is determined and arranged. Further, a fan motor cover 30 to be described later is attached from above the fan motor band 25 to which the fan motor 14M is attached, and then the indoor heat exchanger 10 is attached.
Further, a ventilation unit K is attached to a space space on the left side of the guide rod portion 22B on the left side in the drawing. The ventilation unit K includes a bearing portion that receives one of the support shafts of the cross-flow fan 14F, and includes a damper (not shown), a damper drive mechanism, and a blower mechanism. The damper is controlled to switch in response to the switching signal, and has a so-called ventilating fan function that allows room air to be conducted into the unit body 1 to dry the unit body 1 and components, or to discharge room air to the outside.

図５はファンモータカバー３０を後本体３の後板部３ａに取付けた状態の斜視図である。すなわち、送風機１４を構成するファンモータ１４Ｍに上記ファンモータバンド２５を取付けたうえで、先に説明した案内樋部２２Ａ側部位置の後本体３部位に取付けられる。したがって、上記ファンモータバンド２５の上から上記ファンモータカバー３０が取付けられることになる。
ファンモータカバー３０は、後本体３に設けられる切欠き部１９の左右両側部の近傍部位に取付け具ｄを介して取付け固定される後側取付け部３２と、前ドレンパン１７の側部に取付け具を介して取付けられる前側取付け部を備えている。これら後側取付け部３２と前側取付け部との間には、上記ファンモータバンド２５を介してファンモータ１４Ｍをカバーするカバー部３３ａが設けられる。このカバー部３３ａの両側縁に沿って一体に立上り形成される壁部３３ｂ、３３ｃがあって、これら壁部３３ｂ、３３ｃとカバー部３３ａ上面とで受け部３４が形成される。 FIG. 5 is a perspective view of a state in which the fan motor cover 30 is attached to the rear plate portion 3a of the rear main body 3. FIG. That is, after the fan motor band 25 is attached to the fan motor 14M constituting the blower 14, the fan motor band 25 is attached to the rear main body 3 portion of the guide flange 22A side position described above. Therefore, the fan motor cover 30 is attached from above the fan motor band 25.
The fan motor cover 30 includes a rear attachment portion 32 that is attached and fixed to the vicinity of the left and right side portions of the notch portion 19 provided in the rear main body 3 via an attachment d, and a fixture on the side of the front drain pan 17. The front side attachment part attached via this is provided . A cover portion 33a that covers the fan motor 14M via the fan motor band 25 is provided between the rear attachment portion 32 and the front attachment portion. There are wall portions 33b and 33c that are integrally formed along both side edges of the cover portion 33a, and a receiving portion 34 is formed by the wall portions 33b and 33c and the upper surface of the cover portion 33a.

つぎに、室内熱交換器１０の支持構造について説明する。図６は室内熱交換器１０の側面図、図７は固定部材である固定金具３５の斜視図、図８は補助熱交換器１００Ｂの主熱交換器１００Ａに対する取付け構造図である。
はじめに図７の固定金具３５から説明すると、これは所定の板厚で、ある程度の幅寸法を持った金属板体をプレス加工などにより折曲形成したものである。その一側部の側縁に取付け用孔３６ａが設けられる取付け座３６が一体に折曲形成される。この取付け座３６とは間隔を存して突片部３７が取付け座３６と同一方向に折曲形成される。
固定金具３５は、突片部３７から先の部分で折り返し折曲され、取付け座３６を有する片部とは所定の長さで平行な片部を有する。そして、この平行片部の端縁では略直角方向に折曲され、取付け用孔３８ａを有する取付け部３８が設けられる。取付け座３６を有する片部と、この片部から折り返し折曲される平行片部とで抱持部３９が形成される。 Next, a support structure for the indoor heat exchanger 10 will be described. FIG. 6 is a side view of the indoor heat exchanger 10, FIG. 7 is a perspective view of a fixing bracket 35 as a fixing member, and FIG. 8 is an attachment structure diagram of the auxiliary heat exchanger 100B with respect to the main heat exchanger 100A.
First, the fixing bracket 35 of FIG. 7 will be described. This is a metal plate having a predetermined plate thickness and having a certain width, which is bent by press working or the like. A mounting seat 36 provided with a mounting hole 36a on the side edge of the one side is integrally bent. The projecting piece 37 is bent in the same direction as the mounting seat 36 with a space from the mounting seat 36.
The fixing bracket 35 is folded back at a portion ahead of the projecting piece 37 and has a piece parallel to the piece having the mounting seat 36 by a predetermined length. And the attachment part 38 which is bent in the substantially right angle direction at the edge of this parallel piece part and has the hole 38a for attachment is provided. A holding portion 39 is formed by a piece having the mounting seat 36 and a parallel piece bent back from the piece.

図８に示すように、補助熱交換器１００Ｂ（正確には補助熱交換器部１０Ｃであるが説明の都合上統一する）の下端部に上記固定金具３５の抱持部３９を介挿する。この状態で、補助熱交換器１００Ｂの下面側に取付け座３６および突片部３７が突出し、上面側に取付け部３８が突出する。そして、補助熱交換器１００Ｂと固定金具３５を主熱交換器１００Ａ（正確には後側熱交換器部１０Ｂであるが説明の都合上統一する）上端に沿わせ、かつ固定金具３５の取付け座３６および突片部３７を主熱交換器１００Ａの側端面に当接する。
固定金具３５の取付け座３６と突片部３７は主熱交換器１００Ａを構成する端板Ｔに密着する。端板Ｔの所定部位にはねじ孔が設けられていて、取付け座３６の取付け用孔３６ａをねじ孔に位置合せし取付け具である取付けねじｄを螺挿して固定金具３５の取付け座３６を主熱交換器１００Ａに取付け固定する。この状態を図６に示している。補助熱交換器１００Ｂは固定金具３５の抱持部３９で抱持固定されていて、主熱交換器１００Ａに対する補助熱交換器１００Ｂの位置合せと固定が正確になされる。 As shown in FIG. 8, the holding portion 39 of the fixing bracket 35 is inserted at the lower end of the auxiliary heat exchanger 100 </ b> B (precisely, the auxiliary heat exchanger portion 10 </ b> C is unified for convenience of description). In this state, the mounting seat 36 and the protruding piece portion 37 protrude from the lower surface side of the auxiliary heat exchanger 100B, and the mounting portion 38 protrudes from the upper surface side. Then, the auxiliary heat exchanger 100B and the fixing bracket 35 are placed along the upper end of the main heat exchanger 100A (precisely, the rear heat exchanger section 10B is unified for convenience of description), and the mounting seat for the fixing bracket 35 36 and the projecting piece 37 are brought into contact with the side end face of the main heat exchanger 100A.
The mounting seat 36 and the projecting piece 37 of the fixing bracket 35 are in close contact with the end plate T constituting the main heat exchanger 100A. A screw hole is provided in a predetermined portion of the end plate T. The mounting hole 36a of the mounting seat 36 is aligned with the screw hole, and a mounting screw d as a mounting tool is screwed in to attach the mounting seat 36 of the fixing bracket 35. It is attached and fixed to the main heat exchanger 100A. This state is shown in FIG. The auxiliary heat exchanger 100B is held and fixed by the holding portion 39 of the fixing bracket 35, so that the auxiliary heat exchanger 100B is accurately positioned and fixed with respect to the main heat exchanger 100A.

図９は室内熱交換器１０を後本体３に取付けする前の状態を説明する図、図１０は室内熱交換器１０を取付けた状態を示す図、図１１はファンモータカバー３０の前面を覆う遮蔽板３１と室内熱交換器１０一部を示す図である。
図９に示すようにファンモータカバー３０を後本体３に取付けたあと、固定金具３５で補助熱交換器１００Ｂを抱持固定した主熱交換器１００Ａを後本体３に取付ける。後本体３の背面部の後板部３ａに設けられる上記切欠き部１９の左右両側部近傍にはすでに、ファンモータカバー３０の後側取付け部３２が取付けられている。 9 is a view for explaining a state before the indoor heat exchanger 10 is attached to the rear main body 3, FIG. 10 is a view showing a state where the indoor heat exchanger 10 is attached, and FIG. 11 covers the front surface of the fan motor cover 30. It is a figure which shows the shielding board 31 and some indoor heat exchangers 10. FIG.
As shown in FIG. 9, after the fan motor cover 30 is attached to the rear main body 3, the main heat exchanger 100 </ b> A in which the auxiliary heat exchanger 100 </ b> B is held and fixed by the fixing bracket 35 is attached to the rear main body 3. The rear mounting portion 32 of the fan motor cover 30 is already mounted in the vicinity of the left and right side portions of the notch portion 19 provided in the rear plate portion 3a of the rear portion of the rear main body 3.

また、後本体３の後板部３ａにおける切欠き部１９の一側部近傍部位にはねじ孔４０ａを有する受け座４０が一体に設けられていて、ここに固定金具３５の取付け部３８を載せて取付け用孔３８ａをねじ孔４０ａに対向させ、しかるのち取付け具である取付けねじを螺挿して固定金具３５を後本体３に取付け固定する。この状態で主熱交換器１００Ａの端板Ｔがファンモータカバー３０の受け部３４を構成する内側の立上り壁部３３ｃ上に載り、かつ補助熱交換器１００Ｂを抱持固定する状態の主熱交換器１００Ａが固定金具３５を介して後本体３に取付け固定されることになる。
図１０に示すように、後本体３に取付けられた状態の室内熱交換器１０はファンモータカバー３０の受け部３４に対して、室内熱交換器１０の側部に突出するＵベンドＢや補助配管Ｈあるいはジャンピングパイプ等が収納される。特に、補助配管Ｈは切欠き部１９に挿通され、室外ユニットへ延出されることは上述したとおりである。 In addition, a receiving seat 40 having a screw hole 40a is integrally provided in the vicinity of one side portion of the notch portion 19 in the rear plate portion 3a of the rear main body 3, and a mounting portion 38 of the fixing bracket 35 is placed thereon. Then, the mounting hole 38a is made to face the screw hole 40a, and then a mounting screw as a mounting tool is screwed to fix the fixing bracket 35 to the rear body 3. In this state, the end plate T of the main heat exchanger 100A is placed on the inner rising wall portion 33c constituting the receiving portion 34 of the fan motor cover 30, and the main heat exchanger is in a state of holding and fixing the auxiliary heat exchanger 100B. The container 100A is attached and fixed to the rear main body 3 via the fixing bracket 35.
As shown in FIG. 10, the indoor heat exchanger 10 attached to the rear main body 3 has a U bend B and an auxiliary that protrude from the side of the indoor heat exchanger 10 with respect to the receiving portion 34 of the fan motor cover 30. A pipe H or a jumping pipe is stored. In particular, as described above, the auxiliary pipe H is inserted into the notch 19 and extended to the outdoor unit.

このようにして室内熱交換器１０の側端部が後本体３に取付け固定される。固定金具３５は室内熱交換器１０の前面側に突出することなく、小型ですむ。コスト的に良影響を与えるとともに、前面パネル２の設計自由度が増し、前面パネル２が与える圧迫感の軽減化を得られる。そして固定金具３５は、主熱交換器１００Ａに対して補助熱交換器１００Ｂを抱持固定でき、位置決め精度の向上と位置決め強度の増大を図れる。
室内熱交換器１０の側部に突出するＵベンドＢ、補助配管Ｈ、ジャンピングパイプ等がファンモータカバー３０の受け部３４に収容されるので、これらＵベンドＢ等から滴下するドレン水が受け部３４に受けられ、送風機ファンモータ１４Ｍが濡れることがない。 In this way, the side end portion of the indoor heat exchanger 10 is attached and fixed to the rear body 3. The fixing bracket 35 does not protrude to the front side of the indoor heat exchanger 10 and can be small. In addition to having a good impact on cost, the degree of freedom of design of the front panel 2 is increased, and the feeling of pressure given by the front panel 2 can be reduced. The fixing bracket 35 can hold and fix the auxiliary heat exchanger 100B to the main heat exchanger 100A, and can improve the positioning accuracy and increase the positioning strength.
Since the U bend B, the auxiliary pipe H, the jumping pipe, and the like that protrude from the side of the indoor heat exchanger 10 are accommodated in the receiving portion 34 of the fan motor cover 30, the drain water dripping from these U bend B and the like is received by the receiving portion. 34, the blower fan motor 14M does not get wet.

後本体３に補助配管Ｈが挿通する切欠き部１９を設けたので、後本体３の強度が低下して補強が必要となる。上述の構成を実施すれば、切欠き部１９の左右両側部近傍にファンモータカバー３０の取付け部３２を取付け固定し、一側部近傍に固定金具３５の取付け部３８を取付け固定したので、両部材３０，３５の取付けと後本体３の後板部３ａの補強を兼用できる。
図１１に示すように、室内熱交換器３の側部から突出するＵベンドＢ等の前面部に位置して遮蔽板３１が取付けられる。この遮蔽板３１はＵベンドＢ等をカバーする板体であるとともに、上記可動パネル５を駆動する開閉駆動機構の一部が取付けられる。 Since the notch 19 through which the auxiliary pipe H is inserted is provided in the rear main body 3, the strength of the rear main body 3 is lowered and reinforcement is required. If the above-described configuration is performed, the mounting portion 32 of the fan motor cover 30 is mounted and fixed near the left and right side portions of the notch portion 19 and the mounting portion 38 of the fixing bracket 35 is mounted and fixed near one side portion. The attachment of the members 30 and 35 and the reinforcement of the rear plate portion 3a of the rear main body 3 can be combined.
As shown in FIG. 11, a shielding plate 31 is attached to a front surface portion such as a U-bend B protruding from the side portion of the indoor heat exchanger 3. The shielding plate 31 is a plate that covers the U-bend B and the like, and a part of an opening / closing drive mechanism that drives the movable panel 5 is attached to the shielding plate 31.

なお、上記実施例においては主熱交換器端板Ｔがファンモータカバー３０の受け部３４を構成する内側の立上り壁３３ｃに載って、固定金具３５を介して後本体３に取付けられるようにしたが、主熱交換器１００Ａを構成する前後側熱交換器１０Ａ，１０Ｂの相対的な折曲角度に受け部３４の立上り壁形状を合致させることが困難視される。
すなわち、前後側熱交換器１０Ａ，１０Ｂの相対的な折曲角度の成形誤差と、ファンモータカバー３０の取付け誤差と、補助熱交換器１００Ｂを抱持し、かつ主熱交換器１００Ａに取付けられる固定金具３５の取付け誤差および、固定金具３５の後本体３に対する取付け誤差の累計が、前後側熱交換器１０Ａ，１０Ｂの折曲角度と受け部３４立上り壁との隙間になって現れる。ここに隙間が存在すると、完全に熱交換されない生空気が導通するところとなり熱交換効率に悪影響を及ぼすとともに、導通部分に露付きが生じる虞れがある。そのため、上述の誤差の累計があっても隙間の発生を阻止する必要がある。 In the above embodiment, the main heat exchanger end plate T is placed on the inner rising wall 33c constituting the receiving portion 34 of the fan motor cover 30 and attached to the rear main body 3 via the fixing bracket 35. However, it is difficult to match the rising wall shape of the receiving portion 34 with the relative bending angle of the front and rear heat exchangers 10A and 10B constituting the main heat exchanger 100A.
That is, the relative bending angle forming error of the front and rear heat exchangers 10A and 10B, the mounting error of the fan motor cover 30, and the auxiliary heat exchanger 100B are held and attached to the main heat exchanger 100A. The total of the mounting error of the fixing bracket 35 and the mounting error of the fixing bracket 35 to the rear main body 3 appears as a gap between the bending angle of the front and rear heat exchangers 10A and 10B and the rising wall of the receiving portion 34. If there is a gap here, raw air that is not completely heat-exchanged will be conducted, and the heat exchange efficiency will be adversely affected, and there is a possibility that dew will be formed on the conducting part. For this reason, it is necessary to prevent the occurrence of a gap even if the above-described error is accumulated.

図１２はカバー部材５０を取付けた室内熱交換器１０の側面図、図１３は室内熱交換器１０とカバー部材５０の取付け構造を示す斜視図である。
カバー部材５０は、主熱交換器１００Ａを構成する前側熱交換器部１０Ａと後側熱交換器部１０Ｂとの互いの連結部分に沿うように屈曲形成され、これら前後側熱交換器部１０Ａ，１０Ｂのそれぞれの端板Ｔに取付けねじｄを介して取付け固定される熱交換器取付け部５１を備えるとともに、上記ファンモータカバー３０と主熱交換器１００Ａとの間に形成される隙間を覆う隙間カバー部５２を有する。
すなわち、カバー部材５０の熱交換器取付け部５１を基準にして前後側熱交換器部１０Ａ，１０Ｂの折曲角度を調整し、取付け固定するようにしたので、前後側熱交換器部１０Ａ，１０Ｂの折曲角度の誤差を吸収して、後本体３に対する取付け精度の向上を図れる。また、カバー部材５０の隙間カバー部５２がファンモータカバー３０と主熱交換器１００Ａとの間を完全に覆って隙間を無くすので、生空気の導通がなく、熱交換効率の向上と露付きの防止を得られる。 FIG. 12 is a side view of the indoor heat exchanger 10 to which the cover member 50 is attached, and FIG. 13 is a perspective view showing a structure for attaching the indoor heat exchanger 10 and the cover member 50.
The cover member 50 is formed so as to be bent along the connecting portion between the front heat exchanger portion 10A and the rear heat exchanger portion 10B constituting the main heat exchanger 100A, and the front and rear heat exchanger portions 10A, 10A, A heat exchanger mounting portion 51 mounted and fixed to each end plate T of 10B via a mounting screw d, and a gap that covers a gap formed between the fan motor cover 30 and the main heat exchanger 100A A cover part 52 is provided.
That is, since the bending angle of the front and rear side heat exchanger parts 10A and 10B is adjusted with reference to the heat exchanger attachment part 51 of the cover member 50, the front and rear side heat exchanger parts 10A and 10B are fixed. The accuracy of the mounting angle with respect to the rear main body 3 can be improved by absorbing the error of the bending angle. Further, since the gap cover portion 52 of the cover member 50 completely covers the space between the fan motor cover 30 and the main heat exchanger 100A and eliminates the gap, there is no continuity of raw air, improving heat exchange efficiency and dew condensation. Prevention can be obtained.
