Description

【０００１】
【発明の属する技術分野】
本発明は、室内機と室外機とから構成される分離形空気調和機に係り、特に室外機におけるユニット本体の底部を構成する底板構造に関する。
【０００２】
【従来の技術】
室内機と室外機とから構成される分離形空気調和機が多用される。特に、室外機においては、筐体であるユニット本体の底部をなす底板上に、圧縮機や、室外熱交換器および送風機などが載置固定されている。
【０００３】
この底板は平面視で横長矩形状をなし、周縁に沿って所定高さのフランジ部が一体に設けられ、このフランジ部に対して前面板や側面板などの板体が取付けられる。さらに、上端開口部は天板によって閉塞され、これらでユニット本体が構成される。
【０００４】
図４（Ａ）に示すように、ユニット本体Ｓの四隅には固定用脚ｂが設けられている。これら固定用脚ｂは、被据付け部である据付け台ｃ上に載置され、取付け固定具（固定用ボルト）ｄを用いて取付け固定される。
【０００５】
はじめ上記固定用脚ｂは、底板とは別部品として製作され、一端部が底板の裏面側にたとえばスポット溶接などの固着手段で取付け固定され、取付け用孔が設けられる他端部が底板から外方に延出して取付け固定されていた。
【０００６】
【発明が解決しようとする課題】
しかしながら、固定用脚を底板へ取付けるにあたって、溶接手段を採用すると、金属板腐食防止用の被膜まで焼却除去してしまう。そのため、溶接後に塗装して錆の発生を防ぐ必要があり、手間がかかる。
【０００７】
近時、加工性および耐久性に優れる溶融アルミニウム−亜鉛合金メッキ鋼板（例：ガルバリウム鋼板：商品名）が採用されるようになっているが、この鋼板では溶接を行うことができない。
【０００８】
上記鋼板を用いることを前提として、ねじ止め、リベット止め、カシメ止めなど、溶接以外の手段を用いて底板に固定用脚を取付け固定する技術が採用されるようになった。（例：特開平１１−３３７１１７号公報）
ところが、このような手段によると、取付け工程が増加してコストに悪影響を与えている。また、室外ユニットの据付け時に固定用脚が壁などに接触すると、衝撃の程度によっては固定用脚が捩れたり、極端な場合は底板から脱落することもあって、取付け信頼性が低い。
【０００９】
そこで、図４（Ｂ）に示すように、底板Ｔの周縁に沿って形成されるフランジ部ｆの一部を切欠し、この切欠部分を底板の外方へ突出させた固定用脚ｇが設けられるようになった。
【００１０】
底板Ｔ底面が被据付け部に接触しないよう、固定用脚ｇの両側部に沿って折曲部ｋが形成され、この下端縁が被据付け部に載る。上記固定用脚ｇが底板Ｔに一体に設けられることになり、上述した取付け固定手段が不要となる。
【００１１】
しかしながら、暖房運転時には除霜水が、冷房運転時には結露水が生成され易く、これらドレン水は一旦底板Ｔ上に溜ったあと、固定用脚ｇが設けられるフランジ部ｆの切欠きから外部へ漏れ出てしまう。
【００１２】
一方、固定用脚ｇの剛性保持のため、上面部に矩形状の突部ｈを一体形成しているが、室外機全体の重量は固定用脚ｇの折曲部ｋにかかる。この折曲部ｋは補強構造となっていないので、強度的に不安がある。
【００１３】
そこで、図４（Ｃ）に示すように、複数の突条ｍを所定間隔を存して一体に設けた固定用脚ｇ１に変更することの考えがある。この場合は、上述の構造よりも剛性の増大化を図ることができ、強度的な不安がない。
【００１４】
その反面、各突条ｍが上方に突出するので、底板のフランジ部に取付けられる正面板や背面板などの板体Ｄにおいて、固定用脚ｇ１と対向する下端縁部位を凹状に切欠く必要がある。
【００１５】
切欠き部ｎを設けたままで放置すれば錆の発生があるので、ここに防錆処理を施す必要があり、手間がかかる。また、切欠き部ｎは正面板と背面板に設けられ、特に正面板における切欠き部ｎと、固定用脚ｇ１の突条ｍの存在が目立って外観を損なう。
【００１６】
本発明は、上述の事情を考慮してなされたものであり、その目的とするところは、ユニット本体の底部を構成する底板の剛性増大化を図り、底板における固定用脚の取付け手間を不要として製造性および外観の向上化が得られ、固定用脚が設けられる部位からのドレン水の漏出を阻止して信頼性の高い空気調和機の室外機を提供しようとするものである。
【００１７】

【００２６】
【発明の実施の形態】
以下、本発明の実施の形態を、図面を参照して説明する。
図１は、組立て途中における空気調和機の室外機について、その一部のみ示す斜視図である。
【００２７】
図中１は底板であって、この底板１の周縁に沿ってフランジ部１ａが立設される。このフランジ部１ａに正面板や背面板などの板体が取付けられ、かつ上端部は天板によって閉塞されてユニット本体２が構成される。図では、底板１の一部のみ示し、正面板等の板体は省略している。
【００２８】
上記底板１上における隅部に仕切り板３が立設されていて、ユニット本体２内を二室に仕切っている。仕切り板３から一方（図の右側）の空間スペースを機械室４と呼び、ここには圧縮機が載置されるとともに、サクションカップや四方弁およびこれらを連通する配管群（以上、図示しない）が収容される。
【００２９】
なお、機械室４の側部にはバルブ支持板５が立設されていて、上記配管群と連通するパックドバルブ（図示しない）などが取付け固定される。また、底板１上には３つのゴムブッシュ６が載置されていて、上記圧縮機を弾性的に３点支持するようになっている。
【００３０】
上記仕切り板３で仕切られる他方の空間スペースを熱交換室７と呼び、ここには平面視でほぼＬ字状に形成される室外熱交換器８が載置される。この室外熱交換器８は上記仕切り板３の背面側まで回り込むよう形成される。さらに、室外熱交換器８と対向して送風機と、この送風機を支持する支持ベース（いずれも図示しない）が取付けられる。
【００３１】
上記底板１の周縁に沿って設けられるフランジ部１ａの一部は所定幅寸法で中断状態となり、ここに後述する固定用脚１０が一体に設けられる。この固定用脚１０の一部が底板から外方へ突設され、先に図４で説明したように、被据付け部ｃに取付け具ｄを介して取付け固定される。
【００３２】
つぎに、上記底板１と固定用脚１０について、図１ないし図３にもとづいて詳述する。なお、図２（Ａ）は底板１の平面図であり、（Ｂ）はＢ−Ｂ線に沿う断面図、（Ｃ）はＣ−Ｃ線に沿う断面図、図３は底板の斜視図である。
【００３３】
底板１の素材は、溶融亜鉛メッキ鋼板に塗装を施した塗装鋼板や、溶融アルミニウム−亜鉛合金メッキ鋼板（例：ガルバリウム鋼板：商品名）等が採用されていて、加工性および耐久性に優れている。
【００３４】
底板１は、金属板をプレス加工してなり、平面視で、前後（奥行き）方向長さよりも左右（幅）方向長さが数倍も長い横長矩形状をなすよう形成される。この底板１の周縁に沿って、底面から上端縁に亘って断面階段状に折曲形成されるフランジ部１ａが一体に設けられる。
【００３５】
上記底板１の底面は、後述する部分を除いて、概略的に、低段面と、中段面と、高段面との三段高さに形成されている。上記機械室４の底面は、一部を除いてほとんど大部分が高段面と中段面とから形成されていて、ここを圧縮機載置面４Ａと呼ぶ。上記熱交換器室７の底面は、一部を除いてほとんど大部分が低段面から形成されていて、ここを熱交換器載置面７Ａと呼ぶ。
【００３６】
上記機械室載置面４Ａと熱交換器載置面７Ａとも、円形や矩形状の突部もしくは凹部が必要カ所に一体に設けられていて、圧縮機や室外熱交換器および送風機支持体の重量に対する強度の保持と、ドレン水の円滑な処理を図っている。
【００３７】
上記固定用脚１０は、底板１の前後長辺部にのみ設けられ、短辺部である左右両側辺には設けられていない。説明の都合上、図の手前側長辺部に設けられる左右一対の固定用脚１０を前側固定用脚１０Ａと呼び、図の後側長辺部に設けられる左右一対の固定用脚１０を後側固定用脚１０Ｂと呼ぶ。
【００３８】
これは、図の手前側長辺部のフランジ部１ａに正面板が取付けられ、据付けた状態で手前側になり、図の後側長辺部のフランジ部１ａに背面板が取付けられ、据付けた状態で背面側になるからである。
【００３９】
前後側固定用脚１０Ａ，１０Ｂとも、底板１の周縁内側から一体に加工展開することにより所定高さに形成される突堤部１１を有し、かつこの突堤部１１から底板外方へ突出するとともに下方斜めに向かって傾斜する傾斜部１２と、この傾斜部１２の下端縁に沿って水平に折曲され実際に被据付け部に載って取付け固定される取付け部１３とから構成される。
【００４０】
なお説明すれば、上記突堤部１１は底板１周縁のフランジ部１ａよりも内側に位置する。突堤部１１の高さ寸法は、底板１底面からフランジ部１ａ上端縁までの高さ寸法よりも小であるが、底板１底面よりは高い寸法に形成される。
【００４１】
特に、図２（Ａ）に示すように、上記突堤部１１基端の幅寸法Ｌａと、上記取付け部１３の幅寸法Ｌｂを比較すると、突堤部１１基端の幅寸法Ｌａは、取付け部１３の幅寸法Ｌｂよりも大（Ｌａ＜Ｌｂ）に形成される。
【００４２】
上記固定用脚１０の突堤部１１基端から傾斜部１２および取付け部１１に亘って、複数の補強用リブ１４が所定間隔を存して並行に、一体に設けられている。これら補強用リブ１４は、断面半円状として板面上に突出している。
【００４３】
上記前側固定用脚１０Ａにおける取付け部１３には、前後方向に長い取付用孔１５が設けられている。上記後側固定用脚１０Ｂにおける取付け部１３には、この先端から傾斜部１２基端に亘って二股状長溝１６が設けられている。
【００４４】
室外機の据付け時において、予め、被据付け部に取付け固定具が仮止めされていて、後側固定用脚１０Ｂを後側にして二股状長溝１６を取付け固定具の杆部に挿入するだけで、室外機の位置決めが容易に行えるようになっている。
【００４５】
上記底板１の前後辺の固定用脚１０Ａ−１０Ｂを結ぶラインにほぼ沿う部位に、その底面が、上記被据付け部面と所定の間隙を存する、もしくは被据付け部面に密着するよう突出する凹陥部１７Ａ，１７Ｂが一体に設けられる。
【００４６】
なお説明すれば、図の右側端部の前後固定用脚１０Ａ−１０Ｂを結ぶラインから±約３０ｍｍ程度ずれた位置に、底板１底面における直径が大で、突出底面の直径が小の、テーパー状に形成される凹陥部１７Ａが一体形成される。
【００４７】
ここでの凹陥部１７Ａの底面は、図２（Ｃ）に示すように、被据付け部面に対して所定間隙ｖ（約３ｍｍ程度）を存して近接するように突出し、かつこの突出底面には排水用孔部１８が設けられる。さらに、底板１底面における凹陥部１７Ａ周縁に沿って、底板面から上方に突出する縁部ａが一体に設けられる。
【００４８】
また、図の左側端部の前後固定用脚１０Ａ−１０Ｂを結ぶラインから±約３０ｍｍ程度ずれた位置に、底板１底面における直径が半円づつ異なり、突出底面の直径が小に形成される凹陥部１７Ｂが一体形成される。
【００４９】
上記凹陥部１７Ｂの底面は、図２（Ｂ）に示すように、被据付け部面と接触するように突出していて、凹陥部１７Ｂの突出底面には排水用孔部１８が設けられる。さらに、底板１底面における凹陥部１７Ｂ周縁に沿って、底板１面から上方に突出する縁部ａが一体に設けられる。
【００５０】
このようにして、底板１に固定用脚１０を一体成形したから、溶接やカシメなどの取付け工程を不要にでき、底板１の製造性が向上して、低価格で信頼性の高い部品を供給できる。
【００５１】
底板１の剛性増大化が得られるとともに、固定用脚１０の突堤部１１を所定の高さに形成したので、底板１上に溜まるドレン水が固定用脚１１から漏出することを阻止して信頼性の向上を得る。
【００５２】
固定用脚１０の取付け部１３の幅寸法Ｌａを小とし、突堤部１１基端の幅寸法Ｌｂを大としたので、底板１から一体形成される部位の幅寸法を十分にとって固定用脚１０の強度の増大を得られる。
【００５３】
固定用脚１０の突堤部１１を底板１のフランジ部１ａよりも内側に設けたので、フランジ部１ａに取付けられる正面板や背面板の内側に突堤部１１が位置し、これら板体の下端部を切欠く必要がなくなって、加工手間と防錆処理が不要となるとともに、外観の向上を得る。
【００５４】
前後の固定用脚１０Ａ−１０Ｂを結ぶラインにほぼ沿った位置に凹陥部１７Ａ，１７Ｂを備えたので、被据付け部が細長い台であったとしても、該ラインで室外機を３点支持することになり、固定用脚１０に対する重量の集中を避けて分散化できる。
【００５５】
凹陥部１７Ａ，１７Ｂ内に底板１上のドレン水が流入したとしても、この底面に設けられる排水用孔部１８から排出させ、ドレン水が凹陥部１７Ａ，１７Ｂ内に溜まることがない。
【００５６】
凹陥部１７Ａ，１７Ｂの周縁に沿って設けられる縁部ａが、底板１上に溜まるドレン水の凹陥部１７Ａ，１７Ｂ内への流入を極力阻止し、かつ底板１の強度増大に役立つ。
【００５７】
【発明の効果】
以上説明したように本発明においては、ユニット本体を構成する底板に、その周縁内側から一体に加工展開して固定用脚を設けたので、底板に対する固定用脚の取付け手間を不要として、底板の製造性を向上させ、低価格で高い信頼性を得るなどの効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to a separation type air conditioner composed of an indoor unit and an outdoor unit, and more particularly to a bottom plate structure that constitutes a bottom part of a unit body in the outdoor unit.
[0002]
[Prior art]
A separate air conditioner composed of an indoor unit and an outdoor unit is often used. In particular, in an outdoor unit, a compressor, an outdoor heat exchanger, a blower, and the like are placed and fixed on a bottom plate that forms the bottom of a unit body that is a casing.
[0003]
The bottom plate has a horizontally long rectangular shape in plan view, and a flange portion having a predetermined height is integrally provided along the periphery, and a plate body such as a front plate or a side plate is attached to the flange portion. Furthermore, the upper end opening is closed by the top plate, and these constitute the unit body.
[0004]
As shown in FIG. 4A, fixing legs b are provided at the four corners of the unit body S. These fixing legs b are placed on an installation table c which is an installation part, and are fixed by using an attachment fixture (fixing bolt) d.
[0005]
First, the fixing leg b is manufactured as a separate part from the bottom plate, and one end is fixedly attached to the back side of the bottom plate by, for example, spot welding or the like, and the other end provided with the mounting hole is removed from the bottom plate. It extended to the direction and was fixed.
[0006]
[Problems to be solved by the invention]
However, if the welding means is used to attach the fixing legs to the bottom plate, the coating for preventing corrosion of the metal plate is incinerated and removed. Therefore, it is necessary to paint after welding to prevent the occurrence of rust, which takes time.
[0007]
Recently, molten aluminum-zinc alloy-plated steel plates (eg, galvalume steel plates: trade names) that are excellent in workability and durability have been adopted, but welding cannot be performed with these steel plates.
[0008]
Assuming that the steel plate is used, a technique for attaching and fixing a fixing leg to the bottom plate using means other than welding, such as screwing, riveting, and caulking, has been adopted. (Example: JP-A-11-337117)
However, according to such a means, the attachment process is increased and the cost is adversely affected. In addition, if the fixing leg comes into contact with a wall or the like during installation of the outdoor unit, the fixing leg may be twisted depending on the degree of impact or may fall off from the bottom plate in an extreme case, so that the mounting reliability is low.
[0009]
Therefore, as shown in FIG. 4 (B), there is provided a fixing leg g in which a part of the flange portion f formed along the periphery of the bottom plate T is cut out and the cut portion is protruded outward of the bottom plate. It came to be able to.
[0010]
A bent portion k is formed along both side portions of the fixing leg g so that the bottom surface of the bottom plate T does not come into contact with the installation portion, and the lower end edge is placed on the installation portion. The fixing leg g is integrally provided on the bottom plate T, and the above-described mounting and fixing means is not necessary.
[0011]
However, defrost water is likely to be generated during heating operation, and dew condensation water is likely to be generated during cooling operation. After the drain water once accumulates on the bottom plate T, it leaks to the outside from the notch of the flange portion f where the fixing leg g is provided. It will come out.
[0012]
On the other hand, in order to maintain the rigidity of the fixing leg g, a rectangular protrusion h is integrally formed on the upper surface part, but the weight of the entire outdoor unit is applied to the bent part k of the fixing leg g. Since the bent portion k does not have a reinforcing structure, there is a concern about strength.
[0013]
Therefore, as shown in FIG. 4C, there is an idea of changing the plurality of protrusions m to the fixing legs g1 provided integrally with a predetermined interval. In this case, the rigidity can be increased more than the above structure, and there is no fear of strength.
[0014]
On the other hand, since each protrusion m protrudes upward, in the plate body D such as a front plate or a back plate attached to the flange portion of the bottom plate, it is necessary to cut out the lower end edge portion facing the fixing leg g1 in a concave shape. is there.
[0015]
If it is left with the notch n provided, rust will be generated, so it is necessary to carry out a rust prevention treatment here, which is troublesome. Further, the notch n is provided on the front plate and the back plate. In particular, the presence of the notch n on the front plate and the protrusion m of the fixing leg g1 is conspicuous and impairs the appearance.
[0016]
The present invention has been made in consideration of the above-mentioned circumstances, and the object of the present invention is to increase the rigidity of the bottom plate constituting the bottom portion of the unit main body, and eliminate the need for mounting the fixing legs on the bottom plate. An improvement in manufacturability and appearance is obtained, and it is intended to provide a highly reliable outdoor unit of an air conditioner by preventing drain water from leaking from a portion where a fixing leg is provided.
[0017]
[Means for Solving the Problems]
The invention of claim 1 made to satisfy the above-mentioned object is to mount and fix an outdoor heat exchanger or the like on the bottom plate forming the bottom of the unit main body as a casing, and to fix the legs provided on the bottom plate. In the outdoor unit of an air conditioner, in which the fixing leg is fixedly attached to the installation part via a fixture, the fixing leg is formed at a predetermined height by being integrally processed from the inner periphery of the bottom plate And a portion that is attached and fixed to the portion to be installed protrudes outside the bottom plate.
[0018]
As a second aspect of the present invention, in the outdoor unit of the air conditioner according to the first aspect, the width dimension of the portion that is attached and fixed to the mounting portion of the fixing leg is formed smaller than the width dimension of the base of the jetty portion. It is characterized by that.
[0019]
According to a third aspect of the present invention, in the outdoor unit of the air conditioner according to the first aspect, a flange portion to which a plate body constituting the unit main body is attached is integrally formed along the peripheral edge of the bottom plate, and the jetty portion of the fixing leg Is located inside the flange portion of the bottom plate.
[0020]
As the fourth aspect, in the outdoor unit of the air conditioner according to the first aspect, the bottom plate has a horizontally long rectangular shape in a plan view, and fixing legs are provided at portions facing the left and right sides of the front and rear long sides, The bottom plate part that is almost along the line connecting the front and rear fixing legs is integrated with a recessed part that protrudes so that the bottom surface is close to the surface of the mounted part with a predetermined gap or is in contact with the surface of the mounted part It is provided in.
[0021]
According to a fifth aspect of the present invention, in the outdoor unit for an air conditioner according to the fourth aspect of the present invention, a drain hole is provided on the projecting bottom surface of the concave portion.
[0022]
According to a sixth aspect of the present invention, in the outdoor unit for an air conditioner according to the fourth aspect of the present invention, an edge that protrudes upward from the bottom plate surface is integrally provided along the periphery of the recessed portion.
[0023]

According to the invention of claim 2, it is possible to obtain an increase in the strength of the fixing leg by sufficiently making the width dimension of the part integrally formed from the bottom plate.
[0024]
According to the invention of claim 3, since the pier portion of the fixing leg is located on the inner side of the flange portion of the bottom plate, it is not necessary to cut out the lower end portion of the front plate and the back plate attached to the flange portion, and the processing labor is reduced. And no rust prevention treatment is required, and the appearance is improved.
According to the invention of claim 4, even if the mounted part is a long and narrow base, the front and rear fixing legs and the recessed part support three points, and the weight is not dispersed in the fixing legs and dispersed. Can be
[0025]
According to the fifth aspect of the present invention, even if drain water flows into the recessed portion from the bottom plate, the drain water is discharged from the drain hole on the bottom surface and does not accumulate in the recessed portion.
According to the sixth aspect of the present invention, the edge provided along the periphery of the recessed portion prevents the drain water accumulated on the bottom plate from flowing into the recessed portion as much as possible, and helps increase the strength of the bottom plate.
[0026]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing only a part of an outdoor unit of an air conditioner during assembly.
[0027]
In the figure, reference numeral 1 denotes a bottom plate, and a flange portion 1 a is erected along the periphery of the bottom plate 1. A plate body such as a front plate or a back plate is attached to the flange portion 1a, and the upper end portion is closed by a top plate to constitute the unit main body 2. In the figure, only a part of the bottom plate 1 is shown, and a plate body such as a front plate is omitted.
[0028]
A partition plate 3 is erected at a corner on the bottom plate 1 to partition the unit body 2 into two chambers. One space (right side in the figure) from the partition plate 3 is referred to as a machine room 4, where a compressor is placed, and a suction cup, a four-way valve, and a group of pipes communicating these (not shown). Is housed.
[0029]
A valve support plate 5 is erected on the side of the machine room 4 and a packed valve (not shown) communicating with the piping group is attached and fixed. Further, three rubber bushes 6 are placed on the bottom plate 1, and the compressor is elastically supported at three points.
[0030]
The other space space partitioned by the partition plate 3 is called a heat exchange chamber 7, and an outdoor heat exchanger 8 formed in an approximately L shape in a plan view is placed here. The outdoor heat exchanger 8 is formed so as to go around to the back side of the partition plate 3. Further, a blower and a support base (both not shown) for supporting the blower are attached to face the outdoor heat exchanger 8.
