Description

本発明は、たとえば天井梁から吊下げ固定され、吹出しダクトを介して被空調室内へ熱交換空気を吹出す、天井埋込み形のダクト式室内機である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, which is a duct-type indoor unit embedded in a ceiling, which is suspended and fixed from, for example, a ceiling beam and blows heat exchange air into an air-conditioned room through a blowout duct.

[特許文献1]には、吸込み口と吹出し口が設けられたユニット本体と、このユニット本体に収納され伝熱管に所定の間隔を存して重合された多数の板状伝熱フィンを複数段に重ねその一部が湾曲した熱交換器と、この熱交換器に送風する電動ファンと、吹出し口の周囲にベルマウスを備えた空気調和機の室外ユニットが開示されている。   In [Patent Document 1], a unit main body provided with a suction port and a blow-out port, and a plurality of plate-like heat transfer fins stored in the unit main body and polymerized at predetermined intervals in a plurality of stages are provided. And an outdoor unit of an air conditioner including a bell mouth around a blowout port, and a heat exchanger having a partially curved heat exchanger, an electric fan for blowing air to the heat exchanger.

前記熱交換器は、少なくともその一部に各熱交換器部用として分割された分割フィンを含み、内側段熱交換器部と外側段熱交換器部に向って短く形成される。すなわち、空気調和機の室外ユニットでは、熱交換器の熱交換面積をより増大すべく直状に形成される熱交換器を、長手方向の中途部で略90°折曲げ、平面視でL字状としている。   The heat exchanger includes divided fins divided for each heat exchanger part at least in a part thereof, and is formed short toward the inner stage heat exchanger part and the outer stage heat exchanger part. That is, in an outdoor unit of an air conditioner, a heat exchanger that is formed in a straight shape so as to further increase the heat exchange area of the heat exchanger is bent approximately 90 ° in the middle in the longitudinal direction, and is L-shaped in plan view. It is in the shape.

そして、この熱交換器を熱交換空気の流通方向に沿って複数(ここでは2列)重ねた熱交換器組立を構成し、熱交換効率の向上を図っている。はじめは互いに同一の長手方向寸法の熱交換器であるので、折曲げ位置をずらして成形することで、折曲げ部は勿論のこと、全体的に隙間が出ないよう、互いに密着した状態で重ねることが可能である。
特開2003−279073号公報
A heat exchanger assembly in which a plurality (two in this case) of these heat exchangers are stacked along the flow direction of the heat exchange air is configured to improve the heat exchange efficiency. At first, the heat exchangers have the same longitudinal dimensions, so they can be overlapped in close contact with each other so that there is no gap as a whole, as well as the bent parts, by forming with the folding position shifted. It is possible.
JP 2003-279073 A

ところで[特許文献1]では、内側段熱交換器部の端部に、断面が略L字形状の端板が取付けられ、この端板の下端部には取付けねじ孔を有する取付け突部が設けられる。その一方で、ユニット本体を構成する底板の立上り部には、取付け用孔が設けられる。
室外ユニットの組立時には、内外側段熱交換器部の一端を、ユニット本体内を機械室と熱交換室に仕切る仕切り板に取付け固定し、内側段熱交換器部他端に設けられる端板を、底板立上り部にねじ止め固定するようになっている。
By the way, in [Patent Document 1], an end plate having a substantially L-shaped cross section is attached to the end portion of the inner stage heat exchanger portion, and a mounting protrusion having a mounting screw hole is provided at the lower end portion of the end plate. It is done. On the other hand, a mounting hole is provided in the rising portion of the bottom plate constituting the unit main body.
When assembling the outdoor unit, one end of the inner / outer stage heat exchanger section is attached and fixed to a partition plate that divides the inside of the unit body into a machine room and a heat exchange chamber, and an end plate provided at the other end of the inner stage heat exchanger section is attached. The bottom plate rises and is fixed with screws.

しかしながら、熱交換器の中途部を折曲げて略L字状に形成するので、曲げ角度のバラツキばかりでなく、折曲げた先の長さ寸法にバラツキが生じ易い。そのため、端板の位置にバラツキがともない、取付け突部の取付けねじ孔と、底板立上り部の取付け用孔との相対的な位置がずれ、ねじの取付けに工数がかかって作業性が悪い。   However, since the middle part of the heat exchanger is bent and formed in a substantially L shape, not only the bending angle varies, but also the length of the bent tip tends to vary. For this reason, there is a variation in the position of the end plate, the relative positions of the mounting screw hole of the mounting protrusion and the mounting hole of the rising portion of the bottom plate are shifted, and man-hours are required for screw mounting, resulting in poor workability.

なお、天井埋込み形のダクト式室内機である空気調和機の室内ユニットにおいては、従来から、単に平板状の熱交換器を傾けた状態で支持する、もしくは平面視で略矩形枠状に成形された熱交換器を搭載していた。前者にあっては、熱交換面積を充分に確保できないし、後者にあっては成形に手間がかかってコストに影響を及ぼしている。   In addition, in an indoor unit of an air conditioner that is a duct type indoor unit embedded in a ceiling, conventionally, a flat heat exchanger is simply supported in an inclined state, or is formed into a substantially rectangular frame shape in plan view. It was equipped with a heat exchanger. In the former case, a sufficient heat exchange area cannot be secured, and in the latter case, it takes time for molding and affects the cost.

そこで、室外ユニットに用いられる平面視で略L字状の前記熱交換器を、前記室内ユニットに採用することが考えられるに至った。しかしながら、室内ユニットは、室外ユニットのように本体内部を仕切る仕切り板を備えておらず、折曲げ角度と折曲げ長さのバラツキを吸収して熱交換器の両端部を取付けるのに手間がかかることが予想される。   Therefore, it has been considered that the heat exchanger having a substantially L shape in plan view used for the outdoor unit is adopted for the indoor unit. However, the indoor unit does not have a partition plate for partitioning the inside of the main body like the outdoor unit, and it takes time and effort to mount both ends of the heat exchanger by absorbing the variation in the bending angle and the bending length. It is expected that.

本発明は前記事情にもとづきなされたものであり、その目的とするところは、平面視で略L字状に形成される熱交換器をユニット本体に取付けるのに、比較的簡単に行えて手間がかからずにすみ、作業性の向上を得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 based on the above circumstances, and its object is to attach a heat exchanger formed in a substantially L shape in a plan view to the unit main body, which is relatively easy and troublesome. It is an object of the present invention to provide an indoor unit of an air conditioner that does not require any work and can improve workability.

前記目的を満足するため本発明は、ユニット本体の一側面に吸込み口、他側面に吹出し口を設け、ユニット本体内部に折曲げ部を介して長辺部と短辺部とで平面視で略L字状に形成した熱交換器を収容し、この熱交換器と吹出し口との間に送風機を配置し駆動にともなってユニット本体外部の空気を吸込み口から吸込んで熱交換器に導き吹出し口から被空調室内へ送風するようにした空気調和機の室内ユニットであり、前記ユニット本体は、熱交換器を構成する短辺部の端部が挿入される凹部を有して熱交換器一端を支持する発泡成形部品である第1の支持部材を備え、さらに熱交換器の長辺部端部に設けられる端板が差し込まれることにより熱交換器他端を支持する第2の支持部材を備えた。   In order to satisfy the above object, the present invention is provided with a suction port on one side surface of the unit main body and a blowout port on the other side surface, and the long side portion and the short side portion are roughly viewed in plan view through a bent portion inside the unit body. An L-shaped heat exchanger is accommodated, a blower is placed between the heat exchanger and the blowout port, and the air outside the unit main body is sucked from the suction port as it is driven, leading to the heat exchanger and the blowout port The air conditioner indoor unit is configured to blow air into the air-conditioned room from above, and the unit main body has a recess into which an end of a short side part constituting the heat exchanger is inserted, and has one end of the heat exchanger. A first support member that is a foam molded part to be supported; and a second support member that supports the other end of the heat exchanger by inserting an end plate provided at the end of the long side of the heat exchanger. It was.

本発明によれば、平面視で略L字状に形成される熱交換器をユニット本体に取付けるのに、比較的簡単に行えて手間がかからずにすみ、作業性の向上を得る等の効果を奏する。   According to the present invention, a heat exchanger formed in a substantially L shape in a plan view can be attached to the unit main body relatively easily and without much labor, improving workability, etc. There is an effect.

That is, the blowout unit 13d includes a ceiling blowout opening 14d that opens from the ceiling plate 2 to the room, and the ceiling blowout opening 14d is shielded by the grill.

つぎに、前記室内ユニットKにおけるユニット本体7の内部構成について説明する。
図3はユニット本体7の概略の横断平面図である。
ユニット本体7は、正面視と側面視および平面視のいずれも矩形状に形成される筐体であって、図3に示す右側面板に吸込み口10が設けられ、前記吸込みダクト11sを介して吸込みユニット13sが接続される。左側面板に2つの吹出し口12が設けられ、前記吹出しダクト11dを介して吹出しユニット13dが接続される。
Next, an internal configuration of the unit body 7 in the indoor unit K will be described.
FIG. 3 is a schematic cross-sectional plan view of the unit body 7.
The unit main body 7 is a housing formed in a rectangular shape in all of the front view, the side view, and the plan view. The right side plate shown in FIG. 3 is provided with a suction port 10 and sucks through the suction duct 11s. The unit 13s is connected. Two outlets 12 are provided in the left side plate, and an outlet unit 13d is connected through the outlet duct 11d.

これら吸込み口10が設けられる側面板16aと、2つの吹出し口12が設けられる側面板16bの、それぞれ下端両側部に、上述した吊下げボルト5に吊持するためのフランジ8(いずれも図示を省略)が設けられている。   The flanges 8 (both shown in the figure) for suspending the suspension bolts 5 on the lower end sides of the side plate 16a provided with the suction port 10 and the side plate 16b provided with the two outlets 12 respectively. (Omitted) is provided.

ユニット本体7内の吸込み口10と吹出し口12との間に、3組の熱交換器である第1の熱交換器Naと、第2の熱交換器Nbおよび第3の熱交換器Ncを組合せてなる熱交換器組立18が収容配置される。熱交換器組立18は、ユニット本体7底部に設けられるドレン受け皿19上に載置され、上端部はユニット本体7を構成する天板に近接する。   Between the inlet 10 and the outlet 12 in the unit main body 7, the first heat exchanger Na, which is a set of three heat exchangers, the second heat exchanger Nb, and the third heat exchanger Nc are connected. A combined heat exchanger assembly 18 is accommodated. The heat exchanger assembly 18 is placed on a drain tray 19 provided at the bottom of the unit body 7, and the upper end is close to the top plate constituting the unit body 7.

後述するように、個々の熱交換器Na〜Ncが平面視で略L字状に形成されていて、これら熱交換器Na〜Nc相互を互いに密着させた状態で組合される熱交換器組立18も、平面視で略L字状に形成されることになる。熱交換器組立18、折曲げ部Rを境に直状長尺部である長辺部Lと、直状短尺部である短辺部Sとからなる。   As will be described later, each of the heat exchangers Na to Nc is formed in a substantially L shape in plan view, and the heat exchanger assembly 18 is combined in a state where these heat exchangers Na to Nc are in close contact with each other. Is also formed in a substantially L shape in plan view. The heat exchanger assembly 18 includes a long side portion L that is a straight long portion and a short side portion S that is a straight short portion, with the bent portion R as a boundary.

なお、前記第1〜第3の熱交換器Na〜Ncおよび、これら熱交換器Na〜Ncを組合せた熱交換器組立18の具体的な構成と、熱交換器組立18のユニット本体7に対する支持構造については後述する。   The first to third heat exchangers Na to Nc, the specific structure of the heat exchanger assembly 18 combining these heat exchangers Na to Nc, and the support for the unit body 7 of the heat exchanger assembly 18 The structure will be described later.

前記熱交換器組立18の長辺部Lが吸込み口10と並行に配置され、この長辺部Lと側面板16bとの間に送風機20が配置される。送風機20は軸方向を側面板16bと並行とし両端面から回転軸が突出する二軸のファンモータFMと、各回転軸に嵌着される多翼型のファン(図示せず)と、このファンを囲むファンケーシングKとからなる。   The long side portion L of the heat exchanger assembly 18 is disposed in parallel with the suction port 10, and the blower 20 is disposed between the long side portion L and the side plate 16 b. The blower 20 has a biaxial fan motor FM in which the axial direction is parallel to the side plate 16b and the rotating shaft projects from both end faces, a multi-blade fan (not shown) fitted to each rotating shaft, and the fan And a fan casing K surrounding the casing.

前記多翼型のファンは、回転にともなって軸方向から熱交換空気を吸込み、周方向へ吹出すようになっている。それぞれのファンケーシングKにおいて、軸方向に沿う両端面にファン吸込み口aが開口される。また、周方向一部にファン吹出し口が設けられ、ユニット本体7の吹出し口12と連通する。   The multi-blade fan sucks heat exchange air from the axial direction as it rotates and blows it out in the circumferential direction. In each fan casing K, fan suction ports a are opened at both end surfaces along the axial direction. Further, a fan outlet is provided in a part of the circumferential direction, and communicates with the outlet 12 of the unit body 7.

つぎに、前記第1〜第3の熱交換器Na〜Ncと、これら第1〜第3の熱交換器Na〜Ncを組合せてなる熱交換器組立18の具体的な構成と、ユニット本体7に対する支持構造について詳述する。
図4は熱交換器組立18を分解した斜視図、図5は熱交換器組立18の側面図、図6は組立てられた熱交換器組立18の斜視図、図7は熱交換器組立18のユニット本体7に対する取付け構造を説明する図である。
Next, a specific configuration of the heat exchanger assembly 18 formed by combining the first to third heat exchangers Na to Nc and the first to third heat exchangers Na to Nc, and the unit body 7 The support structure for will be described in detail.
4 is an exploded perspective view of the heat exchanger assembly 18, FIG. 5 is a side view of the heat exchanger assembly 18, FIG. 6 is a perspective view of the assembled heat exchanger assembly 18, and FIG. It is a figure explaining the attachment structure with respect to the unit main body.

図4、図6、図7に示す熱交換器組立18において、最も内側(向こう側)にある熱交換器を第1の熱交換器Naと呼び、真ん中にある熱交換器を第2の熱交換器Nbと呼び、最も外側(手前側)にある熱交換器を第3の熱交換器Ncと呼ぶ。   In the heat exchanger assembly 18 shown in FIGS. 4, 6, and 7, the heat exchanger located on the innermost side (the other side) is called the first heat exchanger Na, and the heat exchanger in the middle is the second heat exchanger. It is called the exchanger Nb, and the heat exchanger on the outermost side (front side) is called the third heat exchanger Nc.

前記熱交換器組立18は、第1の熱交換器〜第3の熱交換器Na〜Ncを熱交換空気の流通方向に沿って重ね合わせた状態で組合される。各熱交換器Na〜Ncは、所定の間隙を存して並置されるフィンFに対して熱交換パイプPが貫通して設けられるフィンチューブタイプである。(図6のみ符号を付す)
前記熱交換パイプPはU字状に曲成され、一側端に位置するフィンFからU字状曲成部が突出し、他側端に位置するフィンFからU字管の両開口端が突出する。複数のU字管は上下方向に所定の間隔を存してフィンFを貫通していて、この一方の開口端部は分配管に接続され、他方の開口端部は分岐集合管に接続される。
The heat exchanger assembly 18 is combined in a state where the first heat exchanger to the third heat exchangers Na to Nc are overlapped along the flow direction of the heat exchange air. Each of the heat exchangers Na to Nc is a fin tube type in which the heat exchange pipe P is provided so as to penetrate the fin F juxtaposed with a predetermined gap. (Only FIG. 6 is attached)
The heat exchange pipe P is bent in a U-shape, a U-shaped bent portion protrudes from a fin F located at one end, and both open ends of the U-shaped tube protrude from a fin F located at the other end. To do. The plurality of U-shaped pipes pass through the fins F with a predetermined interval in the vertical direction, one opening end of which is connected to the distribution pipe, and the other opening end is connected to the branch collecting pipe. .

したがって、第1〜第3の熱交換器Na〜Ncのそれぞれを構成する熱交換パイプPは、全て1本の分配管と分岐集合管に集中して接続されることになる。さらに、分配管と分岐集合管には冷媒管が接続され、図示しない室外ユニット内の圧縮機や室外熱交換器等の冷凍サイクル構成部品に連通する。   Therefore, all of the heat exchange pipes P constituting each of the first to third heat exchangers Na to Nc are concentratedly connected to one distribution pipe and the branch collecting pipe. Further, a refrigerant pipe is connected to the distribution pipe and the branch collecting pipe, and communicates with refrigeration cycle components such as a compressor and an outdoor heat exchanger in an outdoor unit (not shown).

このようにして構成される第1〜第3の熱交換器Na〜Ncは、はじめは平面視で直状に形成される。そして、この長手方向の中途部で略90°に折曲げられ、平面視で略L字状をなす。具体的には、図3にも示すように、折曲げ部Rを境に、長尺の直状部である長辺部Lと、短尺の直状部である短辺部Sとから構成されることになる。   The first to third heat exchangers Na to Nc configured in this way are initially formed in a straight shape in plan view. And it is bent at about 90 ° in the middle part in the longitudinal direction, and has a substantially L shape in plan view. Specifically, as shown in FIG. 3, it is composed of a long side portion L that is a long straight portion and a short side portion S that is a short straight portion, with the bent portion R as a boundary. Will be.

第1〜第3の熱交換器Na〜Ncは、互いに長辺部Lの端面位置が同一に揃えられるとともに、長辺部Lの側端部から折曲げ部Rを介して短辺部Sの側端部に至るまで、全長に亘って互いに密着される。   As for 1st-3rd heat exchanger Na-Nc, while the end surface position of the long side part L mutually aligns, the short side part S of the side part of the long side part L via the bending part R is mutually aligned. They are in close contact with each other over the entire length up to the side end.

そのために、第1〜第3の熱交換器Na〜Ncは、長辺部Lの端面位置から折曲げ部Rが設けられる位置までが、等間隔でズレて形成される。結果的に、互いの折曲げ部Rの曲率半径の中心位置は同一であるが、曲率半径としては互いに異なるとともに、長辺部Lの長さおよび短辺部Sの長さが異なる。   For this purpose, the first to third heat exchangers Na to Nc are formed at regular intervals from the end surface position of the long side portion L to the position where the bent portion R is provided. As a result, the center positions of the curvature radii of the bent portions R are the same, but the curvature radii are different from each other, and the length of the long side portion L and the length of the short side portion S are different.

そのうえで、第1〜第3の熱交換器Na〜Ncは、互いの長辺部Lの端面を揃えて配置されるので、これら熱交換器Na〜Ncを組合せてなる熱交換器組立18の短辺部S端部は、平面視で段階状に形成されることとなる。   In addition, since the first to third heat exchangers Na to Nc are arranged with the end surfaces of the long side portions L aligned with each other, the shortness of the heat exchanger assembly 18 formed by combining these heat exchangers Na to Nc is short. The side S end is formed in a step shape in plan view.

特に図4および図5に示すように、第1〜第3の熱交換器Na〜Ncにおける、それぞれの長辺部L端面には、フィンFよりも厚板で剛性の大きい端板22a〜22cが設けられている。第2の熱交換器Nbと、第3の熱交換器Ncに取付けられる端板22b、22cは、フィンFの縦横寸法に合せた矩形状のものである。   In particular, as shown in FIGS. 4 and 5, end plates 22 a to 22 c that are thicker and more rigid than fins F are provided on the end surfaces of the long sides L in the first to third heat exchangers Na to Nc. Is provided. The end plates 22b and 22c attached to the second heat exchanger Nb and the third heat exchanger Nc have a rectangular shape matching the vertical and horizontal dimensions of the fins F.

これに対して、第1の熱交換器Naに取付けられる端板22aは、フィンFの縦寸法のみに合せられ、横寸法はフィンF幅から突出する寸法に形成される。さらに、この端板22aは突出端縁から略90°折り曲げられ長辺部Lから突出していて、平面視で略L字状に形成される。   On the other hand, the end plate 22a attached to the first heat exchanger Na is adjusted to only the vertical dimension of the fin F, and the horizontal dimension is formed to project from the fin F width. Further, the end plate 22a is bent approximately 90 ° from the protruding end edge and protrudes from the long side portion L, and is formed in an approximately L shape in plan view.

第1〜第3の熱交換器Na〜Ncそれぞれの長辺部L端面に設けられる端板22a〜2c相互は、2個の熱交固定板22によって一体に連結される。この熱交固定板22は略V字状に形成され、両端部と頂部の位置に取付け用孔が開口される。これら取付け用孔に取付けねじが挿通され、各端板22a〜22cに設けられるねじ孔に螺挿されてなる。   The end plates 22 a to 2 c provided on the end faces of the long sides L of the first to third heat exchangers Na to Nc are connected together by two heat exchanger fixing plates 22. The heat exchanger fixing plate 22 is formed in a substantially V shape, and mounting holes are opened at the positions of both ends and the top. Mounting screws are inserted into these mounting holes, and are screwed into screw holes provided in the end plates 22a to 22c.

また、第1〜第3の熱交換器Na〜Ncそれぞれの短辺部S端面において、第2の熱交換器Nbの短辺部S端面に取付けられる端板23bは、フィンFの縦横寸法に合せられた縦横寸法の矩形状をなす。
第1の熱交換器Naと第3の熱交換器Ncの短辺部S端面に取付けられる端板23a、23cは、縦寸法がフィンFの縦寸法に合せられ、横寸法は並置されるフィンFの側縁に沿って略90°折り曲げられ、平面視で略L字状に形成される。
Moreover, the end plate 23b attached to the short side part S end surface of the 2nd heat exchanger Nb in the short side part S end surface of each of 1st-3rd heat exchanger Na-Nc is the vertical and horizontal dimension of the fin F. It has a rectangular shape with the combined vertical and horizontal dimensions.
The end plates 23a and 23c attached to the end faces of the short sides S of the first heat exchanger Na and the third heat exchanger Nc have the vertical dimension adjusted to the vertical dimension of the fin F, and the horizontal dimension is a fin that is juxtaposed. It is bent approximately 90 ° along the side edge of F, and is formed in an approximately L shape in plan view.

第1〜第3の熱交換器Na〜Ncの短辺部S端面に前記端板23a〜23cが取付けられ、熱交換器組立18が構成される状態で、熱交換器組立18の短辺部S全部を囲むようにして熱交取付け板25が取付けられる。
前記熱交取付け板25は、平面視でコ字状に形成され、第1の熱交換器Naと第3の熱交換器Ncの短辺部側面に沿って折曲げ形成される端板23a、23c部分に密に接する。そして、互いの接触部分は取付けねじによって取付け固定される。
In a state where the end plates 23 a to 23 c are attached to the short side S end faces of the first to third heat exchangers Na to Nc and the heat exchanger assembly 18 is configured, the short side of the heat exchanger assembly 18. The heat exchanger mounting plate 25 is mounted so as to surround the entire S.
The heat exchanger mounting plate 25 is formed in a U shape in a plan view and is bent along the side surfaces of the short sides of the first heat exchanger Na and the third heat exchanger Nc, Close contact with 23c portion. The contact portions of each other are attached and fixed by attaching screws.

すなわち、熱交取付け板25は平面視で段階状に形成される熱交換器組立18の短辺部を囲み、第1〜第3の熱交換器Na〜Ncを一体的に固定する。図6は、以上述べた説明によって組立てられる熱交換器組立18を示している。図7は、組立てられた熱交換器組立18を模式的に示すとともに、ユニット本体7への取付け構造を示している。   That is, the heat exchanger mounting plate 25 surrounds the short side portion of the heat exchanger assembly 18 formed stepwise in plan view, and integrally fixes the first to third heat exchangers Na to Nc. FIG. 6 shows the heat exchanger assembly 18 assembled according to the above description. FIG. 7 schematically shows the assembled heat exchanger assembly 18 and shows a structure for mounting to the unit main body 7.

図3および図7に示すように、ユニット本体7には第1の支持部材27と、第2の支持部材28が取付けられる。
前記第1の支持部材27は、たとえば発泡スチロール材である発泡成形品からなり、前記吹出し口12が設けられる側面板16bの一方の隅部で、かつドレン受け皿19上に設けられている。第1の支持部材27の高さ寸法は、熱交換器組立18の高さ寸法と同一であり、幅寸法は熱交換器組立18の幅寸法よりも大に形成される。
As shown in FIGS. 3 and 7, a first support member 27 and a second support member 28 are attached to the unit body 7.
The first support member 27 is made of, for example, a foamed molded product that is a polystyrene foam material, and is provided on the drain tray 19 at one corner of the side plate 16 b where the blowout port 12 is provided. The height dimension of the first support member 27 is the same as the height dimension of the heat exchanger assembly 18, and the width dimension is formed larger than the width dimension of the heat exchanger assembly 18.

ユニット本体7内部へ突出する第1の支持部材27の端面には、高さ方向に沿って凹部27aが形成されていて、この凹部27aに熱交換器組立18が支持される。すなわち、ユニット本体7の前記部位には、予め第1の支持部材27が取付けられていて、凹部27aをユニット本体7内部に対向させている。   A concave portion 27a is formed along the height direction on the end surface of the first support member 27 protruding into the unit body 7, and the heat exchanger assembly 18 is supported by the concave portion 27a. That is, the first support member 27 is attached to the part of the unit main body 7 in advance, and the concave portion 27 a is opposed to the inside of the unit main body 7.

一方、熱交換器組立18の短辺部S端部には、前述したように端板23a〜23cを介して熱交取付け板25が取付けられる。熱交取付け板25ごと熱交換器組立18を第1の支持部材27の上方部位に対向位置し、そのあと熱交換器組立18を降下させ、短辺部S端部を熱交取付け板25ごと凹部27aに落とし込む。   On the other hand, the heat exchanger mounting plate 25 is attached to the end portion of the short side S of the heat exchanger assembly 18 through the end plates 23a to 23c as described above. The heat exchanger assembly 18 together with the heat exchanger mounting plate 25 is positioned opposite to the upper portion of the first support member 27, and then the heat exchanger assembly 18 is lowered, and the short side S end is aligned with the heat exchanger mounting plate 25. Drop into the recess 27a.

前記第2の支持部材28は、ユニット本体7の側面板16cに取付け固定されていて、この側面板16cの面方向と直交する方向であるユニット本体7内部へ突出する。第2の支持部材28は第1の熱交換器Naの端板22aと重なり合うよう側面板16cから突出して形成される。   The second support member 28 is fixedly attached to the side plate 16c of the unit main body 7 and protrudes into the unit main body 7 in a direction perpendicular to the surface direction of the side plate 16c. The second support member 28 is formed to protrude from the side plate 16c so as to overlap the end plate 22a of the first heat exchanger Na.

第2の支持部材28の高さ寸法は、熱交換器組立18の高さ寸法と同一であり、ユニット本体7内への突出側端縁で高さ方向に離間して、2つの切起し爪からなる掛止部28aが設けられる。これら掛止部28aの切起し面と支持部材28面との間隔は、第1の熱交換器Naの長辺部Lに取付けられる端板22aの板厚よりも僅かに大に形成される。   The height dimension of the second support member 28 is the same as the height dimension of the heat exchanger assembly 18, and is separated in the height direction at the protruding side edge into the unit main body 7, and two cuts and rises are made. A latching portion 28a made of a claw is provided. The distance between the cut-and-raised surface of the latching portion 28a and the surface of the support member 28 is slightly larger than the thickness of the end plate 22a attached to the long side portion L of the first heat exchanger Na. .

このようにして構成される第2の支持部材28も予め、ユニット本体7の所定部位に取付けられ、掛止部28aが設けられる板面をユニット本体7内部に突出させている。一方、熱交換器組立18の長辺部L端部には、前述したように端板22a〜22cが熱交固定板22を介して一体に連結される。   The second support member 28 configured as described above is also attached in advance to a predetermined portion of the unit main body 7, and a plate surface on which the latching portion 28 a is provided protrudes into the unit main body 7. On the other hand, the end plates 22 a to 22 c are integrally connected to the end portion of the long side portion L of the heat exchanger assembly 18 via the heat exchanger fixing plate 22 as described above.

第1の熱交換器Naに取付けられる端板22aの片部が、第2の支持部材28の板面と同一方向に倣う。熱交換器組立18を第2の支持部材28の上方部位に対向位置してから、熱交換器組立18を降下させる。熱交換器組立18の長辺部Lの端部から突出する端板22a先端が第2の支持部材28の掛止部28aに差込まれる。   A portion of the end plate 22 a attached to the first heat exchanger Na follows the same direction as the plate surface of the second support member 28. After the heat exchanger assembly 18 is positioned opposite the upper portion of the second support member 28, the heat exchanger assembly 18 is lowered. The tip of the end plate 22 a protruding from the end of the long side portion L of the heat exchanger assembly 18 is inserted into the latching portion 28 a of the second support member 28.

したがって、熱交換器組立18の長辺部L端部が第2の支持部材28に支持されることになる。しかも、この作業は、前述したように熱交換器組立18の短辺部L端部を第1の支持部材27の凹部27aに挿入する作業と同時に行われる。   Therefore, the long side L end portion of the heat exchanger assembly 18 is supported by the second support member 28. Moreover, this operation is performed simultaneously with the operation of inserting the end portion of the short side L of the heat exchanger assembly 18 into the recess 27a of the first support member 27 as described above.

このようにして、熱交換器組立18の両端部は容易に第1の支持部材27と第2の支持部材28に取付け支持される。いずれの支持部材27、28に対しても単なる掛合作業ですむ。従来のようなねじ止め固定ではないので、孔同士の位置合せをする必要がなく、同時に、かつ容易に行える。   In this way, both end portions of the heat exchanger assembly 18 are easily attached and supported by the first support member 27 and the second support member 28. All the supporting members 27 and 28 need only be engaged. Since it is not conventional screw fixing, it is not necessary to align the holes, and at the same time, it can be easily performed.

第1の支持部材27は凹部27aを備えた発泡成形品であるので、熱交換器組立18の嵌め込みにあたって、ある程度の弾性変形は可能である。第2の支持部材28は切起しからなる掛止部28aを備えたので、熱交換器組立18との掛止にあたって、ある程度の余裕がある。   Since the first support member 27 is a foam-molded product having a recess 27a, a certain amount of elastic deformation is possible when the heat exchanger assembly 18 is fitted. Since the second support member 28 includes the latching portion 28a formed by cutting and raising, there is some allowance for latching with the heat exchanger assembly 18.

すなわち、直状に形成される熱交換器Na〜Ncの中途部を折り曲げて平面視でL字状に形成すると、折曲げ角度のズレが生じたり、折曲げた先の長さ寸法のズレが生じ易い。これに対して第1の支持部材27と第2の支持部材28を備えることにより、ある程度の製作誤差を吸収して、熱交換器組立18の確実で容易な取付けを可能とする。   In other words, if the intermediate part of the heat exchangers Na to Nc formed in a straight shape is bent and formed in an L shape in plan view, the bending angle may be shifted or the length of the bent part may be shifted. It is likely to occur. On the other hand, by providing the first support member 27 and the second support member 28, a certain amount of manufacturing error is absorbed, and the heat exchanger assembly 18 can be reliably and easily attached.

以上のように構成される空気調和機の室内ユニットであり、冷凍サイクル運転の開始とともに送風機20が駆動される。ユニット本体7内部が負圧化し、吸込み口14s周辺の室内3空気が、吸込みユニット13s、吸込みダクト11sおよびユニット本体7の側面板16aに設けられる吸込み口10を介してユニット本体7内部に吸込まれる。   It is an indoor unit of an air conditioner configured as described above, and the blower 20 is driven with the start of the refrigeration cycle operation. The inside of the unit body 7 becomes negative pressure, and the room 3 air around the suction port 14s is sucked into the unit body 7 through the suction port 10 provided on the suction unit 13s, the suction duct 11s and the side plate 16a of the unit body 7. It is.

前記ユニット本体7内において、吸込み口10から吸込まれた室内空気は熱交換器組立18の長辺部Lを流通し、あるいは短辺部Sを流通する。冷凍サイクル運転により、第1〜第3の熱交換器Na〜Ncには冷媒が導かれていて、吸込み口10から第1〜第3の熱交換器Na〜Ncを流通する空気と熱交換する。   In the unit main body 7, the indoor air sucked from the suction port 10 flows through the long side portion L or the short side portion S of the heat exchanger assembly 18. The refrigerant is guided to the first to third heat exchangers Na to Nc by the refrigeration cycle operation, and exchanges heat with the air flowing through the first to third heat exchangers Na to Nc from the suction port 10. .

熱交換した空気は送風機20を構成するファンケーシングKの吸込口aから吸込まれ、吹出し口12から吹出される。さらに、熱交換空気は吹出しダクト11dに導かれ、吹出しユニット13dに集合したあと、天井吹出し口14dから室内へ吹出される。すなわち、室内に対する空調作用がなされる。   The heat-exchanged air is sucked from the suction port a of the fan casing K constituting the blower 20 and blown from the blower port 12. Further, the heat exchange air is guided to the blowout duct 11d, gathers in the blowout unit 13d, and then blown into the room from the ceiling blowout opening 14d. That is, an air conditioning operation is performed on the room.

なお、熱交換器組立18の短辺部Sが平面視で段階状に形成されるが、この短辺部S端部には熱交取付け板25が嵌め込まれ、さらに第1の支持部材27の凹部27aに嵌め込まれている。したがって、熱交換器組立18の短辺部Sに導かれた熱交換空気の全てが、露出している短辺部SのフィンF相互間を流通する。   In addition, although the short side part S of the heat exchanger assembly 18 is formed in steps in a plan view, a heat exchanger mounting plate 25 is fitted into the end part of the short side part S, and further, the first support member 27 It is fitted in the recess 27a. Therefore, all of the heat exchange air guided to the short side portion S of the heat exchanger assembly 18 flows between the fins F of the exposed short side portion S.

すなわち、熱交換器組立18の短辺部S端面と、ユニット本体7の側面板16bとは、ある程度の間隔を存して配置されていて、何も無い状態では熱交換されない生空気が流通してしまう。   That is, the short side S end surface of the heat exchanger assembly 18 and the side plate 16b of the unit main body 7 are arranged with a certain distance, and raw air that is not heat exchanged in a state where there is nothing flows. End up.

しかしながら、ここには第1の支持部材27が取付けられ、平面視で段階状に形成される熱交換器組立18端部には熱交取付け板25が嵌め込まれる。そのため、ユニット本体7の側面板16aと熱交換器組立18の短辺部S端面との間から生空気が流通することが無く、熱交換効率の向上を得られる。   However, the first support member 27 is attached here, and the heat exchanger mounting plate 25 is fitted into the end portion of the heat exchanger assembly 18 that is formed stepwise in plan view. Therefore, raw air does not circulate between the side plate 16a of the unit body 7 and the short side S end surface of the heat exchanger assembly 18, thereby improving the heat exchange efficiency.

また、熱交換器組立18の長辺部L端面と、ユニット本体7の側面板16cとの間も、ある程度の間隔を存して配置されていて、何も無い状態では熱交換されない生空気が流通してしまう。
しかしながら、ここには第2の支持部材28が取付けられ、かつ熱交換器組立18から端板22aが突出する。そのため、ユニット本体7の側面板16cと熱交換器組立18の長辺部L端面との間から生空気が流通することが無く、熱交換効率の向上を得られる。
Further, the long side portion L end face of the heat exchanger assembly 18 and the side plate 16c of the unit body 7 are also arranged with a certain distance, and raw air that is not heat exchanged in the absence of anything. It will circulate.
However, the second support member 28 is attached here, and the end plate 22 a protrudes from the heat exchanger assembly 18. Therefore, raw air does not circulate between the side plate 16c of the unit body 7 and the long side portion L end surface of the heat exchanger assembly 18, and an improvement in heat exchange efficiency can be obtained.

このようにして、吸込み口10からユニット本体7内に吸込まれた全ての熱交換空気は、第1〜第3の熱交換器Na〜Ncを構成する熱交換器組立18のフィンF相互間を流通するので、熱交換効率が損なわれることはない。
なお、以上の構成を採用することにより、第1〜第3の熱交換器Na〜Ncを一体にした熱交換器組立18をユニット本体7内へ組み込みする作業性が向上するばかりではなく、熱交換器組立18の取外しと分解の作業も容易となる。
In this way, all the heat exchange air sucked into the unit body 7 from the suction port 10 passes between the fins F of the heat exchanger assembly 18 constituting the first to third heat exchangers Na to Nc. Since it circulates, heat exchange efficiency is not impaired.
By adopting the above configuration, not only the workability of incorporating the heat exchanger assembly 18 in which the first to third heat exchangers Na to Nc are integrated into the unit body 7 is improved, but the heat The operation of removing and disassembling the exchanger assembly 18 is also facilitated.

ここでは、第1の熱交換器Naと、第2の熱交換器Nbおよび第3の熱交換器Ncで、熱交換器組立18が構成される。これに限定されるものではなく、さらに多くの、あるいは2つの熱交換器の組合せであってもよい。   Here, the heat exchanger assembly 18 is constituted by the first heat exchanger Na, the second heat exchanger Nb, and the third heat exchanger Nc. However, the present invention is not limited to this, and more or a combination of two heat exchangers may be used.

第1〜第3の熱交換器Na〜Ncは、同一形状の熱交換器を用いてL字状に成形したので、既存の設備を用いて製作することができる。これに対して、第1〜第3の熱交換器Na〜Ncを組合せたものと同じ大きさの熱交換器を、1つの熱交換器で構成するためには、新たな製造設備を備える必要があり、製造コストの点で影響を及ぼしてしまう。   Since 1st-3rd heat exchanger Na-Nc was shape | molded in the L shape using the heat exchanger of the same shape, it can be manufactured using the existing installation. On the other hand, in order to configure a heat exchanger having the same size as the combination of the first to third heat exchangers Na to Nc with a single heat exchanger, it is necessary to provide a new manufacturing facility. There is an effect in terms of manufacturing costs.

なお、特に第1の支持部材27は、以下のように構成するとよい。
図8は、変形例を示す第1の支持部材27Aの斜視図である。
基本的に、第1の支持部材27は発泡成形品からなるので、材質的に脆い。金属材もしくは合成樹脂材から構成される前記熱交取付け板25に取付け誤差があって、凹部27aに強制的に挿入すると、破損の虞れがある。
In particular, the first support member 27 may be configured as follows.
FIG. 8 is a perspective view of the first support member 27A showing a modification.
Basically, the first support member 27 is made of a foam-molded product, so that the material is brittle. There is a mounting error in the heat exchanger mounting plate 25 made of a metal material or a synthetic resin material, and if it is forcibly inserted into the recess 27a, there is a risk of damage.

そこで図8に示すように、第1の支持部材27Aの凹部27aを、剛性を有する素材である金属薄板もしくは合成樹脂薄材からなる保護部材30で覆うとよい。
前記保護部材30は、必ずしも板材である必要はなく、発泡樹脂成形品である第1の支持部材27Aの少なくとも凹部27a面を覆う樹脂コーティング膜であってもよい。要は、熱交取付け板25の挿脱にあたって凹部27a面を保護できる素材であればよい。
Therefore, as shown in FIG. 8, the recess 27a of the first support member 27A may be covered with a protective member 30 made of a thin metal plate or a synthetic resin thin material, which is a rigid material.
The protective member 30 is not necessarily a plate material, and may be a resin coating film that covers at least the concave portion 27a surface of the first support member 27A that is a foamed resin molded product. In short, any material can be used as long as it can protect the surface of the recess 27a when the heat exchanger mounting plate 25 is inserted and removed.

図9(A)(B)は、互いに異なる形態の第1の支持部材27B,27Cを示す斜視図である。
図9(A)に示すように、凹部27bの上端部の幅寸法Laは、下端部の幅寸法Lbよりも大に形成される。下端部の幅寸法Lbは、熱交換器組立18の短辺部S端部を嵌め込んだ熱交取付け板25の幅寸法と略同一である。
9A and 9B are perspective views showing first support members 27B and 27C having different forms.
As shown in FIG. 9A, the width dimension La of the upper end portion of the recess 27b is formed larger than the width dimension Lb of the lower end portion. The width dimension Lb of the lower end portion is substantially the same as the width dimension of the heat exchanger mounting plate 25 into which the short side S end portion of the heat exchanger assembly 18 is fitted.

したがって、予め所定位置にセットされた第1の支持部材27Bの上端から熱交換器組立18端部を挿入するのに、幅方向に寸法的な余裕が生じる。熱交換器組立18の端部を第1の支持部材27Bの上端に宛がって手を離せば、熱交換器組立18は自然的に落ちて凹部27bに嵌め込まれる。   Therefore, there is a dimensional margin in the width direction when the end of the heat exchanger assembly 18 is inserted from the upper end of the first support member 27B set in advance in a predetermined position. When the end of the heat exchanger assembly 18 is directed to the upper end of the first support member 27B and the hands are released, the heat exchanger assembly 18 naturally falls and is fitted into the recess 27b.

図9(B)に示すように、第1の支持部材27Cの凹部27cは、上端部を除く全長に亘って熱交換器組立18の熱交取付け板25幅寸法と略同一の幅寸法Lbに形成される。上端面からある程度の深さの範囲は、凹部27cの周方向に沿って広げられた寸法であり、凹部27c上端の幅寸法Lcは、上端部を除く幅寸法Lbよりも大である。   As shown in FIG. 9B, the recess 27c of the first support member 27C has a width dimension Lb that is substantially the same as the width dimension of the heat exchanger mounting plate 25 of the heat exchanger assembly 18 over the entire length excluding the upper end. It is formed. The range of a certain depth from the upper end surface is a dimension widened along the circumferential direction of the recess 27c, and the width dimension Lc of the upper end of the recess 27c is larger than the width dimension Lb excluding the upper end part.

このように構成することで、予め所定位置にセットされた第1の支持部材27Cの上端部に熱交換器組立18の熱交取付け板25下端部を当て、第1の支持部材27Cの上端から熱交換器組立18端部を挿入するのに、容易に作業できる。   With this configuration, the lower end portion of the heat exchanger mounting plate 25 of the heat exchanger assembly 18 is applied to the upper end portion of the first support member 27C set in advance in a predetermined position, and the upper end portion of the first support member 27C is It is easy to work to insert the end of the heat exchanger assembly 18.

また、図9(A)(B)に示す第1の支持部材27B、27Cいずれの凹部27b、27cも、図8で説明したような保護部材30で覆って、熱交換器組立18の挿入時における損傷を防止するように構成するとよい。   Further, the concave portions 27b and 27c of the first support members 27B and 27C shown in FIGS. 9A and 9B are covered with the protective member 30 as described with reference to FIG. 8, and the heat exchanger assembly 18 is inserted. It may be configured to prevent damage in the case.

さらに、熱交換器組立18のユニット本体7への取付け構造は、図10〜図12に示すような実施の形態であってもよい。
図10は組立てられたユニット本体7の横断平面図、図11はユニット本体7の一部縦断正面図、図12はユニット本体7の内部を示す斜視図、図13は前記吸込み口10が設けられる側面板16aを取外して見上げた状態のユニット本体7内部一部の斜視図である。
Further, the structure for attaching the heat exchanger assembly 18 to the unit main body 7 may be an embodiment as shown in FIGS.
10 is a cross-sectional plan view of the assembled unit body 7, FIG. 11 is a partially longitudinal front view of the unit body 7, FIG. 12 is a perspective view showing the inside of the unit body 7, and FIG. 13 is provided with the suction port 10. It is a perspective view of a part of the inside of the unit main body 7 in a state where the side plate 16a is removed and looked up.

特に図11に示すように、熱交換器組立18が載置されるドレン受け皿19を発泡スチロール材から構成し、熱交換器組立18の上端部をユニット本体7の天板16dに設けられる断熱材33に当接させる。
このように、熱交換器組立18の上下端部を天板断熱材33とドレン受け皿19で挟み込んで固定できる。熱交換器組立18のユニット本体7内への取付けが容易であり、作業工程の削減を図れるとともに、製品の廃却時における分解作業も容易となる。
In particular, as shown in FIG. 11, the drain tray 19 on which the heat exchanger assembly 18 is placed is made of a polystyrene foam material, and the upper end portion of the heat exchanger assembly 18 is provided on the top plate 16 d of the unit body 7. Abut.
In this way, the upper and lower ends of the heat exchanger assembly 18 can be sandwiched and fixed between the top plate heat insulating material 33 and the drain tray 19. The heat exchanger assembly 18 can be easily mounted in the unit main body 7, so that the number of work processes can be reduced and the disassembling work at the time of product disposal can be facilitated.

特に図10および図12に示すように、ドレン受け皿19に熱交換器組立18の位置決めのための凸部Tが設けられる。この凸部Tは、熱交換器組立18の長辺部Lに対向して2ヶ所、短辺部Sに対向して1ヶ所程度あればよい。
前記凸部Tの存在により、熱交換器組立18のドレン受け皿19面方向への位置ズレが規制される。組立時においては、熱交換器組立の位置が容易に決まり、他の構成部品との組合せが容易になる。
As shown in FIGS. 10 and 12 in particular, the drain tray 19 is provided with a convex portion T for positioning the heat exchanger assembly 18. This convex part T should just be two places facing the long side part L of the heat exchanger assembly 18, and about one place facing the short side part S.
Due to the presence of the convex portion T, the displacement of the heat exchanger assembly 18 in the direction of the surface of the drain tray 19 is restricted. At the time of assembly, the position of the heat exchanger assembly is easily determined, and the combination with other components becomes easy.

なお、組立てられたユニット本体7に対し、誤って落下や衝撃や振動等の外力が加わることがあり、このとき熱交換器組立18の位置がずれると、空気漏れやドレン水飛びなどの不具合が発生する。   Note that an external force such as dropping, impact, or vibration may be applied to the assembled unit body 7 by mistake. If the position of the heat exchanger assembly 18 is shifted at this time, problems such as air leakage or drain water splashing may occur. appear.

しかしながら、ここでは熱交換器組立18の上下方向はドレン受け皿19と天板断熱材33とで位置規制し、水平方向は前記凸部Tで拘束する。そのため、熱交換器組立18に外力が加わっても、熱交換器組立18の位置がずれることはなく、上述の不具合発生を確実に防止できる。   However, here, the position of the heat exchanger assembly 18 in the vertical direction is restricted by the drain tray 19 and the top plate heat insulating material 33, and the horizontal direction is restricted by the projection T. Therefore, even if an external force is applied to the heat exchanger assembly 18, the position of the heat exchanger assembly 18 does not shift, and the occurrence of the above-described problems can be reliably prevented.

図13は、熱交換器組立18に端板35を設け、この端板35をユニット本体7に設けられる掛止爪36に差し込んで取付けた状態を示している。
すなわち、上述の実施の形態では、熱交換器組立18の長辺部L端部に取付けられる端板22aを、ユニット本体7に取付けた熱交取付け板28の掛止部28aに差し込んで取付けるようにしたが、これに限定されるものではない。
FIG. 13 shows a state in which an end plate 35 is provided in the heat exchanger assembly 18 and this end plate 35 is inserted and attached to a latching claw 36 provided in the unit main body 7.
That is, in the above-described embodiment, the end plate 22a attached to the end portion of the long side L of the heat exchanger assembly 18 is inserted and attached to the latching portion 28a of the heat exchange attachment plate 28 attached to the unit body 7. However, the present invention is not limited to this.

前記端板22aをユニット本体7の側面板16cに当接するよう延出させた前記端板35であって、この端板35端縁をユニット本体7に設けられる前記掛止爪36に差し込む構造とする。   The end plate 35 extended from the end plate 22a so as to abut on the side plate 16c of the unit body 7, and an end edge of the end plate 35 is inserted into the latching claw 36 provided in the unit body 7. To do.

熱交換器組立18のユニット本体7への取付けが容易であることには変りがない。前記端板35は、熱交換器組立18端部とユニット本体側面板16cとの間隙を閉塞して、この間隙に導かれようとする熱交換空気の流通を阻止する。したがって、いわゆる「遮蔽板」とも呼べることになる。   The mounting of the heat exchanger assembly 18 on the unit main body 7 is easy. The end plate 35 closes the gap between the end portion of the heat exchanger assembly 18 and the unit main body side plate 16c and prevents the flow of heat exchange air to be guided into the gap. Therefore, it can also be called a “shielding plate”.
