【発明の属する技術分野】
本発明は、室内を壁掛けにて空調するセパレート形エアコン、床暖房エアコン、および、給湯機などの機能を担う空気調和機等の室外ユニットに関するもので、特に、取扱者側にたち運搬時の取り扱い性にをよくする取っ手部の構造に係わるものである。
【０００２】
【従来の技術】
従来室外ユニットに取っ手のあるものとして、例えば特開２００２−８１６９６号公報がある。係る構造は上板の平面の一部を側方に延ばして側板よりも突出させ、周囲を下方に向けて折り曲げたフランジ部と上記側板により囲まれた下向き開口部を取っ手として形成している。上板の周囲同一高さになっているフランジ部の先端形状については通常の切断状態にあり、特に工夫の提案はされていない。また、上端は側板の上端の取っ手対応部以外に設けた段差部にフランジ部を嵌合し、取っ手対応部では段差部を設けずに側板の最上段にある水平フランジに載せて上板を支える箱体構造が記載されているが、室外ユニットの移動、運搬、据え付けなどを行う場合の取扱者の立場からみた取っ手部の安全性や箱体のたわみおよび変形に対応できる強度形態ついて配慮が望まれるものであった。

【発明が解決しようとする課題】
上記した従来の室外ユニットにおいては次に記載する点の配慮がなされてなかった。切断されたままに近い形状は鋭利であり、取っ手開口部に通常の動作で手を挿入するときにけが負う心配がある。取っ手は必ずしも重心ラインにあるものでなく、また、運搬の際にユニットが傾くことがあるが、手の側方が開口部の縁に触れた場合にけがを負う心配がある。また、取っ手の根元には大きな応力がかかるが、これに対応する構造が示唆されていない。取っ手に曲げモーメントが加わるによって、取っ手はもとより側板及び上板にたわみが生じ取扱者に不安感を与えるばかりか、永久変形を伴う心配がある。取っ手開口部が真下に向いているので、目視し難く、手を挿入するときに取扱者に不安感を与える。上板を側板の最上段の水平フランジに載せる面接触構造は、取っ手に曲げモーメントが加わると、剥離と接触が生じたりきしむ異音を発することがあり、取扱者に不安を与える。
【０００５】
本発明の目的は、上記項目の問題点をなくすこと、あるいは少なくすることができる空気調和機等の室外ユニットを提供することにある。
【０００６】
【課題を解決するための手段】
上記課題を解決するための手段を以下に記述する。
【０００７】
すなわち、上端に箱体内方に落ち込む段差部のある側板と、下向きの周囲フランジ部を有し天面の一部が側板位置より側面外方に突出する上板を備え、前者の段差部に後者の周囲フランジ部を嵌合して外箱を構成し、上記上板は突出部を取っ手となし、突出部の根元のフランジ先端を内方天面に向けて折り返した構造を有するものであるから、開口部の根元の縁部に丸みがつくので手の挿入時のけがを負うことが少なくなり、また、折り返しで二重板となるので強度が大になり、意匠もよくなる。また、上板材を薄くしても取っ手をふくむ箱体のたわみや変形を少なくできるものである。
【０００８】
また、突出部の根元に、前記側板の段差面に平行に対応して接するプレ突出面を構成し、プレ突出面のフランジ先端を内方天面に向けて折り返した構造にすることにより厚み増しとなり、側板の段差部との密着が得られ、側板との嵌合一体化が強くなり、特に、側板および上板についてのを含むたわみおよび変形を少なくできるものである。
【０００９】
また、突出部のフランジは側板位置からの距離を次第に大にする斜部突出面と、側板の短辺に平行な頂部平面を有し、斜部突出面のフランジ先端を内方上面に向けて折り返した構造にすることにより、特に、運搬途中にユニットが傾いても手の側方にけがを負うことがなくなるほか、取っ手のたわみおよび変形を少なくできるものである。
【００１０】
また、突出部のフランジは、プレ突出面と連続して側板位置からの距離を次第に大にする斜部突出面と頂部平面を有し、プレ突出面から斜部突出面にかけてフランジ先端を内方上面に向けて折り返した。あるいは、プレ突出面から頂部平面にかけてフランジ先端を内方上面に向けて折り返した構造にすることにより、折り返し部面積が多くなるので手の挿入時及び運搬時のけがを負うことなくなる。また、開口部側面から根元にかけて二重板または三重板となるので、取っ手はもとより箱体を一層強固なものにできるものである。
【００１１】
また、突出部のフランジ高さは突出部根元側を大に先端側を小となし、併せて、フランジ先端を内方上面に向けて突出部根元側を大に先端側を小に折り返し、フランジの下端位置は突出部根元側より先端側を高くした構造にすることにより、取っ手根元の強度向上に理想的な構造が得られ、たわみおよび変形を少なくできるほか、特に、取っ手の開口部が目視し易いので手の挿入時及び運搬時のけがを負うことがなくなり、少ない材料で折り返しの加工も容易にでき、意匠もよくなる利点がある。
【００１２】
また、上板の突出部の根元に対応する近傍の天面に、取っ手の長手と平行および直角な段絞りラインを配設したことにより、取っ手根元の変形を一層少なくできるばかりか、上板の平面の変形も少なくできるものとなる。
【００１３】
また、以上の構造に加え、突出部の根元に位置して平面部のある折り返し部を構成し、平面部近傍にて側板の段差部に螺子で固定することにより、応力の集中する部分の強化と螺子締め部のゆるみ防止ができるものである。
【００１４】
また、取っ手の長手と平行にならない段絞りラインを配設したことにより、根元の強化に加え、上板への応力を分散でき上板のたわみを少なくできるものとなる。
【００１５】
【発明の実施の形態】
以下本発明に係わる室外ユニットの実施の形態を図面を参照しながら詳細に説明する。
【００１６】
（実施の形態１）図１は室外ユニット箱体の組図、図２は上板平面図、図３上板の側面図、図４、図５、図６は部分断面図である。
【００１７】
図１、図２、図３に於いて、１は側板、２はで側板の上部を内方にへこませた段差部であり、長辺から短辺にかけて設けてあり、先端にわずかにそりをつけてある。３は側面にわずかにふくらみを設けた側面段絞りあって後記するが、上板の天面段絞り７と同様な配設で行われる。４は上板であって、短辺側のほぼ中央を側面外方に一体に、手の断面積よりわずかに広くした突出部５を作り運搬用の取っ手として活用するものである。６は上板の周囲のフランジであって端部を下方に向けて折り曲げてある。折り曲げの高さは図６に示すように前記側板の段差部２の高さ未満にしてあり、取っ手に対応する以外の大部分で段差部２の平坦ラインに接する程度にしてある。７は天面にわずかにふくらみを設けた３個所の天面段絞りであって、絞りライン７ａは短辺の直線部および前記突出部５の頂部（取っ手）に平行なラインと直角なラインが突出部５の両根元（裾）に位置してある。
上記突出部５の構成は、根元にはプレ突出面５ａがあり、その面内に組み立て固定用の螺子穴８がある。続いて斜部突出面５ｂ、続いて頂部平面５ｃの３部所の主面からなっており、図５示すようにいずれもフランジ６の先端を内方上面に向けた折り返し５ｄがつけてあり、３部所で連続している。この場合、プレ突出面５ａは前記側板の段差部２に対向する平行な面を有し、折り返し５ｄの丸みに関しては、ほぼ密着曲げに等しい小なるものとし、折り返し高さは当部フランジ高さより小にしてある。
【００１８】
一方、頂部平面５ｃは図５からわかるように側板１の短辺に平行または上板４の短辺の直線部に平行になっており、根元側ので、フランジ高さを根元側より、フランジ高さより小にし、折り返しの丸みは大に、折り返し高さもフランジ高さに対応させて小にしてあり、上下左右縁には丸みをつけてある。
【００１９】
よって、間に位置する斜部突出面５ｂは、突出根元側ではプレ突出面５ａに続き、突出先端側では頂部平面５ｃに続くものであるので、突出部５のフランジ高さおよび折り返し高さは突出部根元側を大に先端側を小となっている。よって、取っ手部の構成を横からみれば、根元で厚く先端にゆくにつれ厚みが薄く見える形態となっており強度上で安心感を得るものである。
【００２０】
室外ユニットとしてのは箱体の組み立ては、図１に示すように上板のフランジ６を上方から側板の段差部２にかぶせるように嵌合し、プレ突出面の螺子穴８と段差部の螺子穴２ａを合わせて螺子固定される。取っ手の開口部は上記の斜部突出面５ｂ、頂部平面５ｃと側板１で囲まれて構成される。内部機器としては、冷凍サイクルの一機能を担う重量の大なる圧縮機、熱交換器および送風機など（図示省略）が搭載される。熱交換作用は図１においては背面側９から空気を導入し前面側１０から排出して行われる。
【００２１】
以上のごとく構成した室外ユニットは、取っ手にモーメントが加わるときに、最も応力のかかる突出部５の根元を、フランジ６の先端を内方天面に向けて折り返して開口端に丸みがある構造にしていることにより、取り扱い時に手を挿入しても根元でけがをすることが少なくなるほか、取っ手の根元側が二重板となるので根元強度も大となり、取っ手が上板４で一体に構成されるので意匠性もたかいものとなる。また、上板材を薄くしても取っ手をふくむ箱体のたわみや変形を少なくできるものである。
【００２２】
また、根元近傍の段差部２に平行に嵌合する部分から側板位置からの距離が次第に大に突出はじめるすそ野にかけてフランジ６の先端を内方天面に向けて折り返した構造しても強度に関しては当部所のみでもかなり改善が得られる。
【００２３】
また、図６に示すようにプレ突出面５ａを設けて段差部２に面密着で固定されている構造は三重板が一体となって強固なものとなり、特に側板１にかかる荷重が面となるので、単独でも上板天面のたわみを少なくできるばかりか、取っ手の強化に加えて側板１および上板４の変形を含む取っ手のたわみおよび変形を少なくできる。
【００２４】
また、斜部突出面５ｂの折り返し５ｄの形成は、特に内部機器の重心片寄りなどでユニットが傾いて手の側方が触れたりこすれたりした場合に、しかも、運搬途中で手が離せない場合にもけがを少なくできるという利点があほか、二重板になるのでとっての左右方向の変形を少なくできる。
【００２５】
また、頂部平面５ｃには折り返しを付けずに、根元のプレ突出面５ａから斜部突出面５ｂ全長にかけて折り返し５ｄを形成しても、丸みの存在によりけがを負うことも少なくできるほか、モーメントに対しての強度は一層大なるものが得られ、取っ手のたわみを少なくでき、側板１、上板４のたわみおよび変形も少なくできる。
【００２６】
図でしめした実施例のごとく根元のプレ突出面５ａから斜部突出面５ｂ、頂部平面５ｃにかけて折り返し５ｄを形成のものは、上記各々のケースで記述した利点を網羅しており、一層上下左右の変形防止の強化ができ、開口部縁の広い領域の丸みの形成によりけが防止に関する安全性一段と向上させ、広い領域で二重板で根元では三重板となるので取っ手はもとより箱体全体のたわみや変形の防止に優れたものである。
【００２７】
また、突出部５のフランジ高さはプレ突出面のに合わせて突出部根元側を大に先端側をそれより小となし、併せてフランジ先端を内方上面に向けて突出部根元側を大に先端側を小に折り返し形成してあるので、前記した各所構造の利点に加え、特に、安全性に関しても取っ手の間口部をを斜め方向から目視できるので取扱者が安心して手をかけることができるばかりか、上板４の板取り最大長を最小限に少なくできるのと、全体的にまるみがあり根元が大であるので、取っ手構成としては強度的に理想的なものが得られることになる。取扱者に対して、やわらかな感じを与え安心感も与える意匠性も高いものである。併せて、頂部の折り返し高さが少ないので加工が容易である利点がある。
【００２８】
上板４に関しては、図２に示すように取っ手の根元に対応する近傍の天面にて、取っ手の長手と平行な絞りライン７ａおよび直角な絞りライン７ａを配設してあるので、取り扱い時には取っ手根元に集中するモーメントが加わるのに対抗し、天面のたわみを少なくできる。したがって、プレ突出面の効果とあわせて取っ手先端が上方に傾くのを低減できる。側板１に設けた絞りライン３ａの効果も同様ある。
【００２９】
突出部５の根元に位置して平面部のある折り返し５ｄを構成し、平面部の近傍にて前記側板の段差部２に螺子固定するので、段差部と面接触で固定されることとなり、応力が分散する方向にあるので、取っ手根元の変形はもとより、連なる側板１、上板４のたわみを低減できる効果がある。また、この種構造は螺子が緩んだ状態で運搬されることが恐いものであるが、折り返し５ｄがあることによりバネワッシャーと同じ効果が得られので螺子固定が確実で、ゆるむこともほとんどなくすことができる。
【００３０】
また、上記のように上板４のたわみを低減できることから、従来のような側板最上段の支え用フランジを設ける必要はなくなり、側板の段差部２をほぼ全長にわたり設けた構造にしてある。よって、相互でのきしみ音発生の問題を少なくでき、加工の工程も少なくできるものである。
【００３１】
（実施の形態２）図７は上板の天面段絞りの形態のみを変えた他の実施例である。１１は天面に六角形の天面段絞りを複数も受けたものであって、その絞りライン１１ａは短辺の直線部、および、突出部５の頂部（取っ手の長手）と平行にならないラインを有し、突出部５の両根元（裾）の近傍にＶの字に配設したものである。
【００３２】
これにより、取り扱い時には取っ手の根元に加わるモーメントに対抗し、また、応力が上板中央側へ伝わるのを分散でき、たわみを少なくできる利点がある。意匠としても斬新なものが得ることができる。
【００３３】
【発明の効果】
上端に箱体内方に落ち込む段差部のある側板と、下向きの周囲フランジ部を有し天面の一部が側板位置より側面外方に突出する上板を備え、前者の段差部に後者の周囲フランジ部を嵌合して外箱を構成し、上記上板は突出部を取っ手となし、突出部の根元のフランジ先端を内方天面に向けて折り返した構造としたので、安全で、強度に優れるのでたわみおよび変形の少ないものとなり、意匠にも優れ、薄い材料で製作できる室外ユニットを提供できる。
【００３４】
また、根元に折り返しをつけて段差部に面接触となるプレ突出面は集中応力をやわらげ、側板を含め周囲の変形を少なくでき、螺子固定時のゆるみも防止できる。
【００３５】
また、取っ手のフランジを根元側で下端位置を低くし高さを大にする構造により少ない材料で手の挿入および加工が容易なものを提供できる。
【００３６】
また、取っ手のプレ突出面から頂部平面にかけて折り返す構造により一層安全性と、変形防止効果を高いものを得ることができる。
【００３７】
加えて、取っ手根元近傍に天面の絞りラインを配設は上板のたわみも少なくできる。
【００３８】
以上のように、本発明は少ない材料で強度を大にでき、意匠性にも優れ、取扱者に対しても安全で、しかも、不安感を与えない空気調和機等の室外ユニットを提供できるものである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an outdoor unit such as a separate type air conditioner that air-conditions a room by hanging it on a wall, a floor heating air conditioner, and an air conditioner that performs functions such as a water heater. It is related to the structure of the handle to improve the sex.
[0002]
[Prior art]
As a conventional outdoor unit having a handle, there is JP-A-2002-81696, for example. In such a structure, a part of the plane of the upper plate is extended laterally so as to protrude from the side plate, and a flange portion bent downward and a downward opening surrounded by the side plate are formed as handles. The distal end shape of the flange portion at the same height around the upper plate is in a normal cutting state, and no particular proposal has been made. In addition, the upper end is fitted with a flange portion to a step portion provided other than the handle corresponding portion at the upper end of the side plate, and the handle corresponding portion supports the upper plate by mounting on the horizontal flange at the uppermost stage of the side plate without providing a step portion. Although the box structure is described, consideration should be given to the safety of the handle from the standpoint of the operator when moving, transporting, and installing the outdoor unit, and to consider the strength form that can respond to the bending and deformation of the box. Was to be done.

[0004]
[Problems to be solved by the invention]
In the conventional outdoor unit described above, the following points have not been considered. The shape that is almost cut is sharp, and there is a risk of injury when a hand is inserted into the handle opening by a normal operation. The handle is not always at the center of gravity line, and the unit may tilt during transportation, but there is a risk that the side of the hand may be injured if it touches the edge of the opening. In addition, although a large stress is applied to the base of the handle, a structure corresponding to this is not suggested. When a bending moment is applied to the handle, not only the handle but also the side plate and the upper plate are bent, giving a sense of anxiety to the operator, and may cause permanent deformation. Since the handle opening is directed right below, it is difficult to visually recognize the handle and gives anxiety to the operator when inserting the hand. In the surface contact structure in which the upper plate is placed on the uppermost horizontal flange of the side plate, if a bending moment is applied to the handle, peeling and contact may occur, or a squeaking noise may be generated, giving anxiety to the operator.
[0005]
An object of the present invention is to provide an outdoor unit such as an air conditioner that can eliminate or reduce the problems of the above items.
[0006]
[Means for Solving the Problems]
The means for solving the above problems will be described below.
[0007]
That is, a side plate having a stepped portion which falls into the inside of the box at the upper end, and an upper plate having a downward peripheral flange portion and a part of the top surface protruding outward from the side plate position to the side plate position are provided. The outer plate is formed by fitting the surrounding flanges of the outer box, and the upper plate has a structure in which the protrusion is a handle and the flange tip at the base of the protrusion is folded toward the inner top surface. In addition, the edge at the base of the opening is rounded, so that injuries during insertion of the hand are reduced, and since it is folded back to form a double plate, the strength is increased and the design is improved. Further, even if the upper plate material is thinned, the bending and deformation of the box body including the handle can be reduced.
[0008]
Also, at the base of the protruding portion, a pre-projection surface is formed which is in contact with the step surface of the side plate in parallel with the step surface of the side plate, and the thickness of the pre-projection surface is increased by folding the front end of the flange toward the inner top surface. Thus, close contact with the step portion of the side plate is obtained, and fitting and integration with the side plate are strengthened. In particular, bending and deformation including the side plate and the upper plate can be reduced.
[0009]
In addition, the flange of the protruding portion has a slope protruding surface that gradually increases the distance from the side plate position, and a top flat surface parallel to the short side of the side plate, with the flange tip of the slope protruding surface facing the inner upper surface. By using the folded structure, in particular, even if the unit is tilted during transportation, no injury is caused to the side of the hand, and the bending and deformation of the handle can be reduced.
[0010]
In addition, the flange of the protruding portion has a slope protruding surface and a top flat surface that gradually increase the distance from the side plate position continuously from the pre-projection surface, and the flange tip extends inward from the pre-projection surface to the oblique projection surface. Turned back towards the top. Alternatively, by forming a structure in which the front end of the flange is folded toward the inner upper surface from the pre-projection surface to the top flat surface, the area of the folded portion is increased, so that injury is not injured when inserting the hand or carrying the hand. In addition, since a double plate or a triple plate is formed from the side surface of the opening to the base, the box as well as the handle can be further strengthened.
[0011]
Also, the height of the flange of the protruding part is large at the base of the protruding part and small at the tip side. The lower end position has a structure in which the tip side is higher than the base of the protruding part, so that an ideal structure for improving the strength of the base of the handle can be obtained, bending and deformation can be reduced, and especially, the opening of the handle can be visually checked. Since it is easy to perform, it is possible to prevent injuries when inserting and carrying the hand, and it is possible to easily perform the folding process with a small amount of material, thereby improving the design.
[0012]
In addition, by disposing a step drawing line parallel and perpendicular to the length of the handle on the top surface near the base of the protrusion of the upper plate, not only can the deformation of the handle base be reduced further, but also the upper plate The deformation of the plane can be reduced.
[0013]
In addition to the above structure, by forming a folded part with a flat part located at the root of the protruding part and fixing it to the step part of the side plate near the flat part with a screw, the part where stress concentrates is strengthened And the screw tightening portion can be prevented from loosening.
[0014]
In addition, by providing a step drawing line that is not parallel to the length of the handle, in addition to strengthening the root, the stress on the upper plate can be dispersed and the deflection of the upper plate can be reduced.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of an outdoor unit according to the present invention will be described in detail with reference to the drawings.
[0016]
(Embodiment 1) FIG. 1 is an assembled view of an outdoor unit box, FIG. 2 is a plan view of an upper plate, FIG. 3 is a side view of the upper plate, and FIGS. 4, 5, and 6 are partial cross-sectional views.
[0017]
1, 2 and 3, reference numeral 1 denotes a side plate, and 2 denotes a stepped portion in which the upper part of the side plate is inwardly recessed. The step is provided from the long side to the short side. Is attached. Reference numeral 3 denotes a side step stop having a slight swelling on the side surface, which will be described later. Reference numeral 4 denotes an upper plate, which is formed with a projecting portion 5 which is slightly wider than the cross-sectional area of the hand, and is used as a handle for transportation by integrating the center of the short side with the outside of the side surface. Reference numeral 6 denotes a flange around the upper plate, the end of which is bent downward. As shown in FIG. 6, the height of the bent portion is smaller than the height of the step portion 2 of the side plate, and is almost in contact with the flat line of the step portion 2 except for the portion corresponding to the handle. Reference numeral 7 is a top surface step stop having three bulges on the top surface, and a stop line 7a has a line perpendicular to a straight line portion on the short side and a line parallel to the top (handle) of the protrusion 5. It is located at both roots (hems) of the protrusion 5.
The configuration of the protruding portion 5 has a pre-protruding surface 5a at the base, and a screw hole 8 for assembling and fixing in the surface. Subsequently, it is composed of three main surfaces, that is, an inclined projecting surface 5b and a top flat surface 5c. As shown in FIG. 5, all of the flanges 6 have a folded back 5d with the tip of the flange 6 facing the inner upper surface. It is continuous in three places. In this case, the pre-projection surface 5a has a parallel surface facing the stepped portion 2 of the side plate, and the roundness of the folded back 5d is set to be as small as almost the same as the close bending, and the folded height is larger than the height of the flange at this portion. It is small.
[0018]
On the other hand, the top flat surface 5c is parallel to the short side of the side plate 1 or parallel to the linear portion of the short side of the upper plate 4 as can be seen from FIG. The height of the fold is large, the height of the fold is small corresponding to the height of the flange, and the upper, lower, left and right edges are rounded.
[0019]
Therefore, since the inclined protruding surface 5b located therebetween is continuous with the pre-protruded surface 5a on the protruding root side and continues on the top flat surface 5c on the protruding tip side, the flange height and the folded height of the protruded portion 5 are The base of the protrusion is large and the tip is small. Therefore, when the configuration of the handle portion is viewed from the side, the handle portion is thicker at the root and thinner toward the tip, so that a sense of security can be obtained in terms of strength.
[0020]
As shown in FIG. 1, the assembling of the box as an outdoor unit is performed by fitting the flange 6 of the upper plate so as to cover the step portion 2 of the side plate from above, and the screw hole 8 of the pre-projecting surface and the screw of the step portion. The screw is fixed by aligning the holes 2a. The opening of the handle is constituted by being surrounded by the above-mentioned oblique projecting surface 5b, top flat surface 5c and side plate 1. As the internal devices, a heavy compressor, a heat exchanger, a blower, and the like (not shown) that perform one function of the refrigeration cycle are mounted. In FIG. 1, the heat exchange operation is performed by introducing air from the back side 9 and discharging air from the front side 10.
[0021]
The outdoor unit configured as described above has a structure in which, when a moment is applied to the handle, the root of the protruding portion 5 that is most stressed is turned back with the tip of the flange 6 facing the inner top surface, and the opening end is rounded. By doing so, in addition to reducing the risk of injury at the base even if the hand is inserted during handling, the base side of the handle is a double plate, so the root strength is also large, and the handle is integrally configured with the upper plate 4 Therefore, the design is also high. Further, even if the upper plate material is thinned, the bending and deformation of the box body including the handle can be reduced.
[0022]
In addition, the strength of the flange 6 may be reduced even if the distal end of the flange 6 is folded toward the inner top surface from a portion fitted in parallel with the stepped portion 2 near the root to a skirt where the distance from the side plate position gradually starts to protrude. A considerable improvement can be obtained by our office alone.
[0023]
Further, as shown in FIG. 6, the structure in which the pre-projection surface 5a is provided and is fixed to the step portion 2 by surface contact is solid with the triple plate, and the load applied to the side plate 1 is particularly a surface. Therefore, the bending of the top surface of the upper plate alone can be reduced, and the bending and deformation of the handle including the deformation of the side plate 1 and the upper plate 4 can be reduced in addition to the strengthening of the handle.
[0024]
In addition, the bent portion 5d of the inclined protruding surface 5b is formed especially when the unit is tilted due to the deviation of the center of gravity of the internal device and the side of the hand touches or rubs, and when the hand cannot be released during transportation. In addition to the advantage that injuries can be reduced, the double-sided plate can reduce the deformation in the left-right direction.
[0025]
Even if the top flat surface 5c is not folded and the folded surface 5d is formed from the pre-projection surface 5a at the base to the entire length of the oblique projection surface 5b, injuries due to the presence of roundness can be reduced, and the moment can be reduced. A higher strength can be obtained, the bending of the handle can be reduced, and the bending and deformation of the side plate 1 and the upper plate 4 can be reduced.
[0026]
As shown in the embodiment shown in the figure, the folded-back portion 5d formed from the pre-projection surface 5a at the base to the inclined portion projection surface 5b and the top flat surface 5c covers the advantages described in the above cases. Can be strengthened to prevent deformation, and the roundness of the wide area of the opening edge can be increased to further improve the safety of injury prevention, and the wide area becomes a double plate with a triple plate at the root, so the entire box as well as the handle is bent. And it is excellent in preventing deformation.
[0027]
The height of the flange of the protruding portion 5 is set to be larger at the base of the protruding portion according to the pre-projection surface, and smaller at the tip side, and at the same time, the base of the protruding portion is larger with the flange front facing the inner upper surface. In addition to the advantages of the various structures described above, the front end of the handle can be viewed obliquely from the viewpoint of safety. Not only is it possible to reduce the maximum length of the upper plate 4 to a minimum, but also because the whole is rounded and the root is large, an ideal handle structure can be obtained. Become. The design is also high, giving the operator a soft feeling and a sense of security. At the same time, there is an advantage that processing is easy because the folded height of the top is small.
[0028]
With respect to the upper plate 4, as shown in FIG. 2, a drawing line 7a parallel to the longitudinal direction of the handle and a drawing line 7a perpendicular to the handle are provided on the top surface near the base of the handle. It counteracts the moment that concentrates on the base of the handle and reduces the deflection of the top surface. Accordingly, the tip of the handle can be prevented from tilting upward together with the effect of the pre-projection surface. The effect of the aperture line 3a provided on the side plate 1 is the same.
[0029]
A folded portion 5d having a flat portion is formed at the base of the protruding portion 5 and is screw-fixed to the step portion 2 of the side plate in the vicinity of the flat portion. Are in the dispersing direction, so that not only deformation of the handle base but also bending of the continuous side plate 1 and upper plate 4 can be reduced. It is fearful that this kind of structure is transported with the screw loosened, but with the folded back 5d, the same effect as the spring washer can be obtained, so that the screw fixing is secure and almost no loosening Can be.
[0030]
Further, since the bending of the upper plate 4 can be reduced as described above, it is not necessary to provide a supporting flange at the uppermost stage of the side plate as in the related art, and the step portion 2 of the side plate is provided over substantially the entire length. Therefore, the problem of mutual squeak noise generation can be reduced, and the number of processing steps can be reduced.
[0031]
(Embodiment 2) FIG. 7 shows another embodiment in which only the form of the upper surface top stop is changed. Numeral 11 designates a hexagonal top surface step stop which is received on the top surface, and the stop line 11a is a line which is not parallel to the straight portion of the short side and the top of the protruding portion 5 (long side of the handle). , And are arranged in a V-shape in the vicinity of both bases (hems) of the protruding portion 5.
[0032]
Thereby, there is an advantage that the moment applied to the base of the handle during handling can be counteracted, the transmission of the stress to the center of the upper plate can be dispersed, and the deflection can be reduced. A novel design can be obtained.
[0033]
【The invention's effect】
At the upper end, there is a side plate with a step that falls into the inside of the box, and an upper plate that has a downward facing flange and a part of the top surface protrudes outward from the side plate position from the side plate position. The outer plate is constructed by fitting the flanges, and the upper plate has a protrusion as a handle, and the tip of the flange at the base of the protrusion is folded back toward the inner top surface, so it is safe and strong Therefore, it is possible to provide an outdoor unit which is less bent and deformed, has an excellent design, and can be made of a thin material.
[0034]
In addition, the pre-projection surface that is folded back at the root and comes into surface contact with the step portion can reduce the concentrated stress, reduce the deformation of the surroundings including the side plate, and prevent loosening at the time of fixing the screw.
[0035]
In addition, a structure in which the lower end of the handle is lowered at the base side and the height of the handle is increased to provide a material that is easy to insert and process with a small amount of material.
[0036]
In addition, a structure in which the handle is folded back from the pre-projection surface to the top flat surface can achieve a higher safety and a higher deformation preventing effect.
[0037]
In addition, the arrangement of the top-side drawing line near the base of the handle can reduce the deflection of the upper plate.
[0038]
As described above, the present invention can provide an outdoor unit such as an air conditioner that can increase strength with a small number of materials, is excellent in design, is safe for a user, and does not cause anxiety. It is.
