Description

【０００１】
【発明の属する技術分野】
【０００２】
本願発明は、空気調和機のケーシング構造に関するものである。
【従来の技術】
【０００３】
例えば、空気調和機の室外機の設置作業時とか保守管理作業時においては、該室外機の上面側から所要の作業を行うことが必要になる場合がある。このような場合、上記室外機の高さ寸法が小さい時には問題はないが、高さ寸法が大きく作業者が床面に立ったままでは作業を行えないような時には、例えば脚立等の踏み台を用意し、この踏み台を用いて作業を行うことが必要となる。
【発明が解決しようとする課題】
【０００４】
ところが、このように室外機の上面側での作業に際して、その都度、適宜の踏み台を用意することは、作業の煩雑化を招来し作業性の低下につながるため、作業コストの低減という点において好ましくない。
【０００５】
また、室外機の上面側での作業を踏み台を用いることなく可能とする手段として、該室外機のケーシングに踏み台部材を設けることが考えられるが、かかる専用部材の設置は部品点数の増加あるいはその取付工数の増加によって室外機のコストアップの一因ともなるので、好ましい手段とは言い難い。
【０００６】
そこで本願発明は、空気調和機の上面側での作業を脚立等を用いることなく容易に且つ安全に行い得るようにした空気調和機のケーシング構造を提案することを主たる目的としてなされたものである。
【課題を解決するための手段】
【０００７】
本願発明ではかかる課題を解決するための具体的手段として図１〜図５に例示するように、次のような構成を採用している。
【０００８】
本願発明の空気調和機のケーシング構造では、ケーシング１の壁面１ｃに、指掛部１２と足掛部１４とを備えた作業用部材１０を取り付けているが、その場合、上記作業用部材１０は樹脂材により一体形成し、上記壁面１ｃに設けた取付穴４に嵌合状態で固定している。
【０００９】
上記作業用部材１０はその前面に略横長矩形状の開口１７を設け、該開口１７の上縁側に上記指掛部１２を、下縁側に上記足掛部１４を、それぞれ形成している。
【００１０】
上記開口１７の奥側には上記ケーシング１の内方へ突出する空間部１３を設けるとともに、上記足掛部１４を上記空間部１３側から上記開口１７を通してその前方へ延出させている。
【００１１】
上記足掛部１４の前端縁には、該前端縁から後方へ下降傾斜して延びる脚部１５が設けられていて上記脚部１５を上記取付穴４の下側縁部の外面に当接させている。
【００１２】
上記足掛部１４の上面には滑り止め１６，１６，・・が設けられている。
【００１３】
上記滑り止め１６は上記開口１７の面方向に略直交する方向に延びる凸条とされている。
【発明の効果】
【００１４】
本願発明ではかかる構成とすることにより次のような効果が得られる。
【００１５】
（１）本願発明にかかる空気調和機のケーシング構造によれば、ケーシング１の壁面１ｃに、指掛部１２と足掛部１４とを備えた作業用部材１０を取り付けているので、例えば空気調和機の全高が高く且つその設置作業時とか保守管理作業時においてその上面側での作業を必要とするような場合、作業者は上記足掛部１４に足を掛けて体を持ち上げることで当該作業が可能となり、例えば従来のように当該作業の都度、脚立等の踏み台を容易する必要がある場合に比して、作業が簡易且つ迅速となり作業性が向上する。
【００１６】
また、上記作業用部材１０は指掛部１２と足掛部１４とを一体的に備えているので、例えばこれら両者を別体構成としてそれぞれ個別に配置する場合に比して、部材点数の低減とか取付作業工数の低減によりコストダウンが図れることになる。
【００１７】
（２）また、本願発明にかかる空気調和機のケーシング構造によれば、上記作業用部材１０を一体形成し、上記壁面１ｃに設けた取付穴４に嵌合状態で固定しているので、例えば上記足掛部１４に足を掛ける場合、該足掛部１４にかかる荷重（主として、作業者の体重）が上記取付穴４部分から上記ケーシング１側に効率良く分散され、これによって上記作業用部材１０の高い支持強度が得られ、その使用上の信頼性が確保されることになる。
【００１８】
（３）本願発明にかかる空気調和機のケーシング構造によれば、上記作業用部材１０の前面に略横長矩形状の開口１７を設け、該開口１７の上縁側に上記指掛部１２を、下縁側に上記足掛部１４を、それぞれ形成しているので、該開口１７によって上記指掛部１２を把持する時における指挿入スペース及び上記足掛部１４に足を掛ける時の足先挿入スペースが確保され、該指掛部１２あるいは足掛部１４を使用しての作業の安全性が確保されるとともに、上記指掛部１２にかかる上向き荷重は上記取付穴４の上側縁部を介して上記壁面１ｃ側に、上記足掛部１４にかかる下向き荷重は上記取付穴４の下側縁部を介して上記壁面１ｃ側に、それぞれ確実に分散支持され、該指掛部１２あるいは足掛部１４の使用時における信頼性が確保される、等の効果が得られる。
【００１９】
（４）また、本願発明にかかる空気調和機のケーシング構造によれば、上記開口１７の奥側に上記ケーシング１の内方へ突出する空間部１３を設けるとともに、上記足掛部１４を上記空間部１３側から上記開口１７を通してその前方へ延出させて設けているので、上記足掛部１４に必要な足掛スペースを、上記作業用部材１０の上記ケーシング１の内側の機内スペース側への突出量を可及的に小さく抑えた状態で確保することができ、機内スペースの有効活用による空気調和機のコンパクト化と足掛け作業時の安全性の確保との両立が可能となる。その際、足掛部１４の前端縁には該前端縁から後方へ下降傾斜して伸びる脚部１５が設けられていて、同脚部１５を上記取付穴４の下側縁部の外面に当接させているので、足掛部１４にかかる下向き荷重を確実にケーシング壁面１ｃに伝達することができる。
【００２０】
なお、本願発明にかかる空気調和機のケーシング構造において、上記足掛部１４の上面に滑り止め１６，１６，・・を設けた場合は、上記足掛部１４へ足先を掛けての作業時における安全性がさらに向上することになる。
【００２１】
また、本願発明にかかる空気調和機のケーシング構造において、上記滑り止め１６を、上記開口１７の面方向に略直交する方向に延びる凸条とした場合は、上記作業用部材１０の型成形時において上記滑り止め１６の延出方向と型抜き方向とが合致し、成形型の構造の簡略化と型抜き作業の容易化が図れ、上記作業用部材１０の製造コストの低廉化、延いては該作業用部材１０を備えた空気調和機のコストダウンが期待できる。
【発明の実施の形態】
【００２２】
以下、本願発明を好適な実施形態に基づいて具体的に説明する。
【００２３】
図１には、セパレート型空気調和機の室外機Ｚを示している。この室外機Ｚは、大人の身長近くの高さ寸法をもつ（図５を参照）縦長形態の室外機であって、縦長矩形状のケーシング１を備えている。このケーシング１は、その前面壁１ａに吹出口２を備えるとともに、その上面壁１ｂは着脱可能な天板３で構成されており、その内部に熱交換器とか圧縮機等の機能部品とか、制御盤等の電気品（図示省略）等を収容している。そして、室外機Ｚの設置作業時とか事後の保守管理作業時には、上記機能部品、電気品等を、必要に応じて、上記天板３を開いて上面壁１ｂ側から、あるいは背面壁１ｄ側から、所要の作業を行うようになっている。
【００２４】
この場合、上記室外機Ｚが高さの大きい縦長形態をもつことから、特に上記天板３側からの作業に際しては、作業者が床面に立った姿勢のままでこれを行うことは困難であって、何らかの踏み台を必要とする。
【００２５】
かかる要求に応えるべく、この実施形態の室外機Ｚにおいては、本願発明を適用して、上記ケーシング１の左右両側面壁１ｃ，１ｃ（特許請求の範囲中の「壁面」に該当する）のそれぞれに次述の作業用部材１０を取り付けている。
【００２６】
上記作業用部材１０は、従来より上記ケーシング１の側面壁１ｃに設けられていた指掛機能のみをもつ指掛部材に足掛機能を付加してこれらを一体化するという基本思想に基づくものであって、図１〜図３に示すように、型成形により一体成形された樹脂成形品でなる横長筺状の本体部１１を備え、上記ケーシング１の側面壁１ｃに形成した横長矩形の取付穴４に機外側から嵌合固定される。
【００２７】
上記本体部１１は、奥壁部１１ａと上壁部１１ｂと下壁部１１ｃ及び左右一対の側壁部１１ｄ，１１ｄを備え、これら各壁部１１ａ〜１１ｄで囲繞された内部を、指あるいは足先の挿入スペースとなる空間部１３としている。また、上記本体部１１の開口面側の上記上壁部１１ｂ寄り位置には、上記左右一対の側壁部１１ｄ，１１ｄに跨がって指掛部１２が横設されており、該指掛部１２によって上記空間部１３の開口面が該指掛部１２の下側に位置する開口１７と該指掛部１２の上側に位置する開口１８の二つに区画されている。
【００２８】
尚、上記指掛部１２は、作業者の指を受けるという機能の外に、上記作業用部材１０の略上半部を上記ケーシング１側の上記取付穴４の上側縁部に固定支持させるという機能をも併せ持つものであって、このため該指掛部１２の下側外周面１２ａはこれを円弧面とするとともに、該指掛部１２の上面側にはその長手方向に延びる嵌合溝１２ｂを形成している。
【００２９】
一方、上記作業用部材１０の上記下壁部１１ｃは、これを足掛部１４として機能させるべく、上記上壁部１１ｂの前端位置よりも所定寸法だけ前方（外方）へ延出させて所要の足掛面積を確保するとともに、その上面には、上記開口１７の面方向に直交する方向に延びる凸条でなる滑り止め１６を該足掛部１４の幅方向に所定間隔で複数本形成している。また、上記足掛部１４の前端縁には、該前端縁から後方へ下降傾斜して延びる脚部１５が設けられている。さらに、上記開口１７の左右両側部には、それぞれ鍔部１９，１９が設けられている。
【００３０】
このように構成された上記作業用部材１０は、上記ケーシング１の左右一対の側面壁１ｃ，１ｃの下端寄り位置、具体的には図４に示すように作業者が腰を落とした姿勢で手が届く高さで、且つ図５に示すように作業者が片足を持ち上げて足先側を掛けることができる高さ位置に形成した上記各取付穴４，４に嵌合固定される。
【００３１】
即ち、図２に示すように、上記作業用部材１０は、上記側面壁１ｃの外側から上記取付穴４に対して、その上端側から挿入し、上記指掛部１２側の上記嵌合溝１２ｂを上記取付穴４の上側縁部に嵌合させる一方、上記足掛部１４の前端側に位置する上記脚部１５を上記取付穴４の下側縁部の外面に当接させるとともに、上記左右一対の鍔部１９，１９をそれぞれ上記取付穴４の側縁部にそれぞれ当接させることで、該ケーシング１側に固定される。
【００３２】
尚、この作業用部材１０の固定状態においては、上記足掛部１４の下面は上記取付穴４の下側縁部の上面に当接しており、上記指掛部１２側の上記嵌合溝１２ｂと共に、該作業用部材１０の上下方向への移動規制を行う。また、上記作業用部材１０の左右方向の移動規制は、上記各側壁部１１ｄ，１１ｄが上記取付穴４の側縁部の端面にそれぞれ当接することで行われる。
【００３３】
このようにして上記作業用部材１０を上記ケーシング１の両側面壁１ｃ，１ｃにそれぞれ取り付けることで、例えば、室外機Ｚの設置作業時等のように該室外機Ｚの運搬とか移動が必要な場合には、図４に示すように、二人の作業者がそれぞれ上記作業用部材１０の指掛部１２を把持してこれを持ち上げることで当該作業を容易且つ安全に行うことができる。
【００３４】
一方、例えば、室外機Ｚの設置作業あるいは設置後の保守管理作業において、該室外機Ｚの上面壁１ｂを構成する上記天板３を開いてここから機内収容部品の点検等を行うような場合には、図５に示すように、作業者は上記作業用部材１０の足掛部１４に片足の足先を掛け、ここに体重を預けて体を持ち上げることで、上記ケーシング１の上面壁１ｂ側での作業を容易且つ迅速に行うことができることになる。
【００３５】
このように、上記ケーシング１の上面壁１ｂ側での作業に際して、上記作業用部材１０の足掛部１４を使用して体を持ち上げることで、例えば従来のように作業の都度、脚立等の踏み台を用意し、これを用いて体を上方へ移動させるような場合に比して、作業が極めて簡略化され、それだけ高い作業性が確保され、作業コストの低廉化が図れるものである。
【００３６】
また、上記作業用部材１０が指掛部１２と足掛部１４とを備えており、これらを必要に応じて選択使用することができることから、例えばこれら両者を別体構成としてそれぞれ個別に配置する場合に比して、部材点数の低減とか取付作業工数の低減が図れ、延いては室外機Ｚの製造コストの低減が可能となる。
【００３７】
さらに、上記作業用部材１０を一体形成し、これを上記壁面１ｃに設けた取付穴４に嵌合固定するようにしているので、例えば、上記足掛部１４に足を掛ける場合、該足掛部１４にかかる荷重（主として、作業者の体重）が上記取付穴４部分から上記ケーシング１側に効率良く分散され、これによって上記作業用部材１０の高い支持強度が得られ、その使用上の信頼性が確保されることになる。
【００３８】
また、上記作業用部材１０の前面に略横長矩形状の開口１７を設け、該開口１７の上縁側に上記指掛部１２を、下縁側に上記足掛部１４を、それぞれ形成しているので、該開口１７によって上記指掛部１２を把持する時における指挿入スペース及び上記足掛部１４に足を掛ける時の足先挿入スペースが確保され、該指掛部１２あるいは足掛部１４を使用しての作業の安全性が確保される。さらに、上記指掛部１２にかかる上向き荷重は上記取付穴４の上側縁部を介して上記壁面１ｃ側に、上記足掛部１４にかかる下向き荷重は上記取付穴４の下側縁部を介して上記壁面１ｃ側に、それぞれ確実に分散支持されるので、該指掛部１２あるいは足掛部１４の使用時における信頼性がさらに高められることになる。
【００３９】
一方、上記作業用部材１０の上記開口１７の奥側に上記ケーシング１の内方へ突出する空間部１３を設けるとともに、上記足掛部１４を上記空間部１３側から上記開口１７を通してその前方へ延出させて設けてるので、上記足掛部１４に必要な足掛スペースを、上記作業用部材１０の上記ケーシング１の内側の機内スペース側への突出量を可及的に小さく抑えた状態で確保することができ、それだけ機内スペースの有効活用による室外機Ｚのコンパクト化と足掛け作業時の安全性の確保との両立が可能となる。また、この場合、上記足掛部１４の上面に滑り止め１６，１６，・・を設けているので、上記足掛部１４へ足先を掛けての作業時における安全性が向上することになる。
【００４０】
さらに、上記作業用部材１０の足掛部１４に設けられた上記滑り止め１６を、上記開口１７の面方向に略直交する方向に延びる凸条としているので、上記作業用部材１０を型成形する場合において、上記滑り止め１６の延出方向と型抜き方向とが合致することとなり、この結果、成形型の構造の簡略化と型抜き作業の容易化が図れ、上記作業用部材１０の製造コストの低廉化、延いては該作業用部材１０を備えた室外機Ｚのコストダウンが期待できることになる。
【００４１】
尚、上記実施形態においては、上記ケーシング１の側面壁１ｃに上記作業用部材１０を一つだけ取り付けているが、本願発明はかかる作業用部材１０の配置個数に限定されるものではなく、例えば上記ケーシング１の高さ寸法に応じて多段に複数個配置することも可能である。
【００４２】
また、上記実施形態においては、上記作業用部材１０を上記ケーシング１の側面壁１ｃに取り付けているが、本願発明はかかる作業用部材１０の取付位置に限定されるものではなく、必要に応じて、上記ケーシング１の何れの壁面にも取り付けることができるものである。

At the same time, the movement of the working member 10 in the vertical direction is restricted. Moreover, the movement restriction | limiting of the left-right direction of the said working member 10 is performed because each said side wall part 11d and 11d contact | abut to the end surface of the side edge part of the said attachment hole 4, respectively.
[0033]
When the working member 10 is attached to the side walls 1c and 1c of the casing 1 in this way, for example, when the outdoor unit Z needs to be transported or moved, such as during installation of the outdoor unit Z, etc. As shown in FIG. 4, the two workers can easily and safely perform the work by holding and lifting the finger hook portions 12 of the working member 10.
[0034]
On the other hand, for example, in the installation work of the outdoor unit Z or the maintenance management work after installation, when the top plate 3 constituting the upper surface wall 1b of the outdoor unit Z is opened and the in-machine housing components are inspected from here As shown in FIG. 5, the worker puts the foot of one foot on the footrest 14 of the working member 10, deposits his weight here, and lifts the body, so that the top wall 1 b of the casing 1 is lifted. The work on the side can be performed easily and quickly.
[0035]
Thus, when working on the upper surface wall 1b side of the casing 1, the body is lifted by using the footrest part 14 of the working member 10, for example, each time a work is carried out as a stepping platform such as a stepladder. Compared to the case where the body is prepared and the body is moved upward using this, the work is extremely simplified, the work efficiency is secured as much, and the work cost can be reduced.
[0036]
Moreover, since the said working member 10 is provided with the finger hook part 12 and the foot hook part 14, and these can be selected and used as needed, these are each arrange | positioned separately as a separate structure, respectively, for example. Compared to the case, the number of members or the number of mounting work steps can be reduced, and the manufacturing cost of the outdoor unit Z can be reduced.
[0037]
Further, since the working member 10 is integrally formed and is fitted and fixed in the mounting hole 4 provided in the wall surface 1c, for example, when the footrest 14 is put on the footrest, The load (mainly the operator's weight) applied to the portion 14 is efficiently distributed from the mounting hole 4 portion to the casing 1 side, whereby a high support strength of the working member 10 is obtained, and its reliability in use. Will be secured.
[0038]
In addition, an opening 17 having a substantially horizontally long rectangular shape is provided on the front surface of the working member 10, and the finger hook 12 is formed on the upper edge side of the opening 17 and the foot hook 14 is formed on the lower edge side. The opening 17 secures a finger insertion space when gripping the finger hanging portion 12 and a foot tip insertion space when placing the foot on the foot hanging portion 14, and uses the finger hanging portion 12 or the foot hanging portion 14. The safety of work is ensured. Further, the upward load applied to the finger hooking portion 12 is directed to the wall surface 1c via the upper edge portion of the mounting hole 4, and the downward load applied to the footrest portion 14 is directed to the lower edge portion of the mounting hole 4. Thus, the wall surface 1c is surely distributed and supported, so that the reliability of the finger hook portion 12 or the foot hook portion 14 during use is further enhanced.
[0039]
On the other hand, while providing the space part 13 which protrudes inward of the said casing 1 in the back | inner side of the said opening 17 of the said working member 10, the said leg part 14 is passed through the said opening 17 and the front from the said space part 13 side. Since it is provided so as to extend, the footrest space necessary for the footrest portion 14 is kept in a state in which the amount of protrusion of the working member 10 toward the in-machine space inside the casing 1 is minimized. Therefore, it is possible to achieve both compactness of the outdoor unit Z by effectively utilizing the space inside the unit and ensuring safety during the stepping work. Further, in this case, since the anti-slip 16, 16,... Are provided on the upper surface of the footrest portion 14, the safety during the work with the foottips hung on the footrest portion 14 is improved. .
[0040]
Further, since the anti-slip 16 provided on the footrest 14 of the working member 10 is a ridge extending in a direction substantially orthogonal to the surface direction of the opening 17, the working member 10 is molded. In this case, the extension direction of the anti-slip 16 and the die cutting direction coincide with each other. As a result, the structure of the molding die can be simplified and the die cutting operation can be facilitated, and the manufacturing cost of the working member 10 can be reduced. Therefore, the cost reduction of the outdoor unit Z provided with the working member 10 can be expected.
[0041]
In the above embodiment, only one working member 10 is attached to the side wall 1c of the casing 1. However, the present invention is not limited to the number of the working members 10 arranged. A plurality of casings 1 may be arranged in multiple stages according to the height of the casing 1.
[0042]
Moreover, in the said embodiment, although the said working member 10 is attached to the side wall 1c of the said casing 1, this invention is not limited to the attachment position of this working member 10, and as needed. It can be attached to any wall surface of the casing 1.
