Description

【０００１】
【発明の属する技術分野】
この発明は、主に空気調和機の室内ユニットに関するもので、詳しくは室内ユニットの据付板への取付け構造を改善して、熱交換器洗浄時に本体背面に洗浄剤が流出しないように、さらに室内ユニットの据付板への取付け部の強度を向上させたものである。但し、この発明は空気調和機に限らず、壁面に据え付けられるその他の機器も含む。
【０００２】
【従来の技術】
図６は従来の空気調和機を背面から見た据付の様子を示す斜視図である。図６において、１は空気調和機本体、２は部屋の壁面に取り付けられた据付板、７は空気調和機本体１の背面の上部両側に設けた引掛部で、空気調和機本体１の背面のプラスチック成型品と一体成型されている。８はこの引掛部７と係合する据付板２の主係止片である。９は空気調和機本体１の背面の上部中央に設けた引掛部で、左右両側の引掛部７と同様、空気調和機本体１の背面のプラスチック成型品と一体成型されている。１０はこの中央の引掛部９と係合する据付板２の補助係止片で、左右両側の引掛部７により空気調和機本体１が係合する主係止片８よりも低い位置に設けられている。
【０００３】
図７は従来の空気調和機本体の据付状態の係止部（両側）の部分断面図、図８は従来の空気調和機本体の据付状態の係止部（中央）の部分断面図である。図７において、１１は空気調和機本体１の背面のプラスチック成型品に設けられたリブで、このリブ１１は据付の配管接続作業時、引掛部７を支点として空気調和機本体を持ち上げるため、引掛部７が主係止片８よりはずれる恐れがあるため、両側主係止部に抜け防止機構となるものである。
【０００４】
図９は従来の空気調和機本体の本体筐体を示す上面図（ａ）、正面図（ｂ）である。図９に示すように、配管接続作業時に空気調和機本体が据付板２から外れることを防ぐのに、左右の引掛部７に抜け防止機構であるリブ１１を設ける必要がある。空気調和機本体１の背面のプラスチック成型品にリブ１１を形成するために、プラスチック成型金型の構成上、筐体の背面風路側及び天面側に開口部を有する。また、中央引掛部９も相似設計のため左右の引掛部７同様、風路側及び、天面側に開口部を有する。
【０００５】
次に動作について説明する。部屋の壁面に取り付けされた据付板２の上部両側の主係止片８に空気調和機本体１の背面に上部両側に設けた引掛部７を係止させて据え付ける。この時、空気調和機本体１の背面の上部中央における引掛部９は、補助係止片１０が据付板２の係止点より低い位置に設けられているので、図８に示すように応力がかからない状態となっている。このため、空気調和機本体１の背面上部に設けた引掛部７が油汚れの付着により破損して落下しても、中央の引掛部９が据付板２の補助係止片１０に係合するので空気調和機本体１がそれ以上落下することはない。この時、据付板２に設けた補助係止片１０は、主係止片８よりも低い位置に設けられているので、空気調和機本体１の重量の重い方側に傾いて保持される。
【０００６】
また、据付の配管接続作業時、引掛部７を支点として空気調和機本体１を持ち上げるため、引掛部７が主係止片８よりはずれる恐れがあるため、前述のように両側主係止部に抜け防止機構であるリブ１１を設けている。
【０００７】
【発明が解決しようとする課題】
従来の空気調和機は、以上のように構成されているので、空気調和機本体の引掛部７に対向する風路側筐体と主係止片８の天面側に開口部を設けており、熱交換器の洗浄剤等を使用した場合、風路側筐体の開口部より洗浄剤が空気調和機本体の背面側に直接吹き付けられ、壁面等を汚す恐れがあるという問題点があった。
【０００８】
また、係止部天面側に開口部を設けている為、空気調和機本体１と引掛部７の接合面積が小さく、強度的に弱いという問題点があった。
【０００９】
この発明は、上記のような問題点を解消するためになされたもので、配管接続作業時に空気調和機本体が据付板から外れることを防ぐ抜け防止機能を失うことなく、筐体背面に開口部を設けないようにして、熱交換器洗浄剤の漏れによる部屋の壁面の汚れを防止する空気調和機を提供することを目的とする。
【００１０】
また、抜け防止機能を有する係止部以外の天面側に開口部を設けないようにして、空気調和機本体と引掛部の結合強度を改善した空気調和機を提供することを目的とする。

【００２４】
【発明の実施の形態】
以下、この発明の実施の形態を図に基づいて説明する。
実施の形態１．
図１乃至５は実施の形態１を示す図で、図１は空気調和機を背面から見た据付の様子を示す斜視図、図２は空気調和機本体の据付状態の係止部（両側）の部分断面図、図３は空気調和機本体の据付状態の係止部（中央）の部分断面図、図４は本体筐体の上面図（ａ）と正面図（ｂ）、図５は図１に示す空気調和機本体の両側の係止部が破損した状態を示す説明図である。
【００２５】
図１において、１は空気調和機本体、２は壁面に取り付けられた据付板、３は空気調和機本体１の背面の上部両側に設けた引掛部で、空気調和機本体１の背面のプラスチック成型品と一体成型されている。４はこの引掛部３と係止する据付板２の主係止片である。５は空気調和機本体１の背面の上部中央に設けた抜け防止部で、左右両側の引掛部３と同様、空気調和機本体１の背面のプラスチック成型品と一体成型されている。６はこの中央の抜け防止部５と対向する据付板２の補助係止片で、左右両側の引掛部３により空気調和機本体１が係止する主係止片４よりも低い位置に設けられている。
【００２６】
図２は空気調和機本体の据付状態における左右両側の引掛部３の係合状態を示しているが、主係止片４により引掛部３の下端部が支持されている。主係止片４は抜け防止機能を有さないものである。そのため、引掛部３には抜け防止のための部材を設ける必要がないので、開口部も設けられていない。筐体に開口部がないので、熱交換器の洗浄剤が壁面がわに漏れる恐れがない。また、引掛部３の天面に開口部がないので、空気調和機本体１と引掛部３との接合面積が確保でき強度が上がる。
【００２７】
図３は中央の抜け防止部５の係合状態を示しているが、補助係止片６が左右両側の主係止片４よりも低い位置に設けられているので、抜け防止部５と補助係止片６は係合しない。即ち、補助係止片６には応力はかからない。補助係止片６の先端をくの字に曲げて抜け防止形状を形成しており、抜け防止部５は補助係止片６の先端が引掛かるように段差１２を設けてあるため、配管据付作業時、引掛部３を支点として空気調和機本体１を持ち上げることによる、引掛部３の外れを防ぐことを可能としている。抜け防止部５の筐体側に段差１２を設けるために、プラスチック成型上抜け防止部５の天面に開口部を設ける必要がある。
【００２８】
従って、図４に示すように本体筐体の風路側には開口部はなく、抜け防止部５の天面側にのみ開口部が設けられている。中央部は抜け防止機構が設けられると共に、また、通常は補助係止片６には応力はかからない構成となっているため、引掛部３が油汚れの付着等により破損して落下しても、補助係止片６で空気調和機本体１の重量を支え、空気調和機本体１は重い方側に傾いて保持される。
【００２９】
次に動作について説明する。壁面に取り付けられた据付板２の上部両側の主係止片４に空気調和機本体１の背面に上部両側に設けた引掛部３を係止させて据え付ける。この時、空気調和機本体１の背面の上部中央に設けた抜け防止部５は、補助係止片６が据付板２の係止点より低い位置に設けられているので、図３に示すように応力がかからない状態となっている。
【００３０】
このため、空気調和機本体１の背面上部に設けた引掛部３が油汚れの付着によりクレージングを起こして破損して落下しても、図５に示すように中央の抜け防止部５が据付板２の補助係止片６に係合するので空気調和機本体１がそれ以上落下することはない。この時、据付板２に設けた補助係止片６は、主係止片４よりも低い位置に設けられているので、空気調和機本体１の重量の重い方側に傾いて保持される。
【００３１】
また、空気調和機本体１の係止部に対向する筐体風路側に開口部を設けないことにより、熱交換器の洗浄剤等を吹きかけられても、空気調和機内部より背面への熱交換器の洗浄剤等の侵入を防ぐことを可能にしたものである。
【００３２】
また、補助係止片６の先端をくの字に曲げて抜け防止形状を形成しており、抜け防止部５は補助係止片６の先端が引掛かるように引掛形状部の一例の段差を設けてあるため、配管据付作業時、引掛部３を支点として空気調和機本体１を持ち上げることによる、引掛部３の外れを防ぐことを可能としている。
【００３３】
上述の実施の形態では、据付板２の左右に２個の主係止片４と、中央に１個の抜け防止機能を有する補助係止片６を設けたものを示したが、この発明はこれに限定されない。据付板２の係止片は３個以上あれば何個でもよい。また、抜け防止機能を有する係止片も１個以上あれば何個でもよい。例えば、全ての係止片が抜け防止機能を有するものでもよい。但し、抜け防止機能を有する係止片を用いると、引掛部の天面に開口部を設けることになるので、空気調和機本体１と引掛部との接合強度が低下する。その点では抜け防止機能を有する係止片は少ない方がよい。
【００３４】
引掛部３または抜け防止部５が油汚れの付着等により破損して落下しても、通常は応力がかからない係止片で空気調和機本体１を支えるために、通常は応力がかからない係止片が最低１個は必要である。また、通常は応力がかからない係止片の位置は、いずれかの引掛部３または抜け防止部５が油汚れの付着等により破損して落下した場合に、通常は応力がかからない係止片が空気調和機本体１を支えることができるような位置に設けることが前提となる。
【００３５】
上述の実施の形態では、空気調和機を例として説明したが、この発明はこれに限定されない。空気調和機以外の機器で、部屋の壁面に据え付ける機器で内部の洗浄が必要なものであれば、本発明の据え付け構造は適用可能である。
【００３６】
【発明の効果】
この発明に係る空気調和機は、据付板に複数の係止片を設け、その係止片の中の１個以上は抜け防止機能を有する係止片とし、抜け防止機能を有する係止片と係合する空気調和機本体の引掛部は、本体筐体背面部分に係止片の先端が引掛かる引掛形状部を有すると共に、天面に引掛形状部を形成するために必要な開口部と下面に係止片との係合に必要な開口部とを有し、他の空気調和機本体の引掛部には係止片との係合に必要な開口部以外には開口部を設けないことにより、本体筐体背面に本体内部と連通する開口部がないので、空気調和機内部からの熱交換器の洗浄剤等の漏れを防ぐことができ、壁面の汚れを防ぐ効果がある。また、抜け防止機能を有する係止片と係合する空気調和機本体の引掛部を除いて、天面に開口部が設けられていないので、引掛部の強度が向上する。
【００３７】
また、この発明に係る空気調和機は、抜け防止機能を有する係止片は、先端が本体筐体に設けられた引掛形状部に引掛かるように曲げられているので、配管据付作業時引掛部を支点として空気調和機本体を持ち上げても、抜け防止機能を有する係止片の先端が引掛形状部に引掛かり引掛部の外れを抑制することができる。
【００３８】
また、この発明に係る空気調和機は、抜け防止機能を有する係止片は、先端がくの字に曲げられていることにより、抜け防止機能を有する係止片の先端が引掛形状部に確実に引掛かる。
【００３９】
また、この発明に係る空気調和機は、本体筐体に設けられた引掛形状部が、段差により構成されたことにより、引掛部の天面に開口部を設けるだけで段差を形成することができる。
【００４０】
また、この発明に係る空気調和機は、据付板に３個以上の係止片を設け、その係止片の中の１個は抜け防止機能を有する係止片とし本体筐体の中央部付近に配置し、左右の係止片が空気調和機本体の引掛部と係合し、中央部に配置された抜け防止機能を有する係止片は通常は空気調和機本体の引掛部と係合せずに応力のかからない構成としたことにより、本体筐体背面に本体内部と連通する開口部がないので、空気調和機内部からの熱交換器の洗浄剤等の漏れを防ぐことができ、壁面の汚れを防ぐ効果がある。また、左右の引掛部には天面に開口部が設けられていないので、引掛部の強度が向上する。
【００４１】
また、この発明に係る空気調和機は、左右の何れかの空気調和機本体の引掛部が破損した場合、中央部に配置された通常は空気調和機本体の引掛部と係合しない係止片が空気調和機本体を支え、空気調和機本体は重量が重い側に傾いて保持されることにより、空気調和機本体は重い方に傾いて保持されるため、異常であることが推測し易く、落下前に対策することが可能で、落下を防止する効果がある。
【００４２】
この発明に係る機器の壁面への据え付け構造は、据付板に複数の係止片を設け、その係止片の中の１個以上は抜け防止機能を有する係止片とし、抜け防止機能を有する係止片と係合する機器本体の引掛部は、本体筐体背面部分に係止片の先端が引掛かる引掛形状部を有すると共に、天面に引掛形状部を形成するために必要な開口部と下面に係止片との係合に必要な開口部とを有し、他の機器本体の引掛部には係止片との係合に必要な開口部以外には開口部を設けないことにより、本体筐体背面に本体内部と連通する開口部がないので、機器内部からの熱交換器の洗浄剤等の漏れを防ぐことができ、壁面の汚れを防ぐ効果がある。また、抜け防止機能を有する係止片と係合する機器本体の引掛部を除いて、天面に開口部が設けられていないので、引掛部の強度が向上する。

BACKGROUND OF THE INVENTION
The present invention mainly relates to an indoor unit of an air conditioner. Specifically, the structure of the indoor unit is improved on the installation plate so that the cleaning agent does not flow out to the back of the main body when cleaning the heat exchanger. The strength of the mounting portion of the unit to the mounting plate is improved. However, the present invention is not limited to the air conditioner, but includes other devices installed on the wall surface.
[0002]
[Prior art]
FIG. 6 is a perspective view showing a state of installation of a conventional air conditioner as seen from the back. In FIG. 6, 1 is an air conditioner body, 2 is an installation plate attached to the wall surface of the room, 7 is a hooking portion provided on both upper sides of the back surface of the air conditioner body 1, It is molded integrally with a plastic molded product. Reference numeral 8 denotes a main locking piece of the mounting plate 2 that engages with the hook portion 7. Reference numeral 9 denotes a hook portion provided at the upper center of the back surface of the air conditioner main body 1, which is integrally formed with a plastic molded product on the back surface of the air conditioner main body 1, as with the hook portions 7 on the left and right sides. Reference numeral 10 denotes an auxiliary locking piece of the mounting plate 2 that engages with the central hooking portion 9 and is provided at a position lower than the main locking piece 8 that the air conditioner body 1 engages with the hooking portions 7 on the left and right sides. ing.
[0003]
FIG. 7 is a partial cross-sectional view of the engaging portion (both sides) in the installed state of the conventional air conditioner body, and FIG. 8 is a partial cross-sectional view of the engaging portion (center) in the installed state of the conventional air conditioner body. In FIG. 7, 11 is a rib provided on a plastic molded product on the back surface of the air conditioner main body 1, and this rib 11 is used to lift the air conditioner main body with the hook portion 7 as a fulcrum at the time of installation pipe connection work. Since the part 7 may be disengaged from the main locking piece 8, the main locking part on both sides serves as a slip prevention mechanism.
[0004]
FIG. 9 is a top view (a) and a front view (b) showing a main body casing of a conventional air conditioner body. As shown in FIG. 9, in order to prevent the air conditioner body from being detached from the installation plate 2 during pipe connection work, it is necessary to provide ribs 11 as a mechanism for preventing the left and right hooks 7 from coming off. In order to form the rib 11 in the plastic molded product on the back surface of the air conditioner main body 1, the plastic molding mold has openings on the back air path side and the top surface side of the casing. Moreover, the central hook part 9 also has an opening part on the air passage side and the top surface side like the left and right hook parts 7 because of the similar design.
[0005]
Next, the operation will be described. The hooks 7 provided on both sides of the upper part of the air conditioner main body 1 are engaged with the main locking pieces 8 on both sides of the upper part of the installation plate 2 attached to the wall surface of the room. At this time, the hook 9 in the upper center of the back surface of the air conditioner main body 1 is provided at a position where the auxiliary locking piece 10 is lower than the locking point of the installation plate 2, so that stress is applied as shown in FIG. It is in a state that does not take. For this reason, even if the hook portion 7 provided on the upper back of the air conditioner body 1 is damaged and dropped due to adhesion of oil stains, the central hook portion 9 engages with the auxiliary locking piece 10 of the installation plate 2. Therefore, the air conditioner main body 1 does not fall any more. At this time, since the auxiliary locking piece 10 provided on the installation plate 2 is provided at a position lower than the main locking piece 8, the auxiliary locking piece 10 is tilted and held toward the heavier side of the air conditioner body 1.
[0006]
Moreover, since the air conditioner main body 1 is lifted by using the hook portion 7 as a fulcrum at the time of installation piping connection work, the hook portion 7 may be detached from the main locking piece 8. A rib 11 is provided as a mechanism for preventing the removal.
[0007]
[Problems to be solved by the invention]
Since the conventional air conditioner is configured as described above, an opening is provided on the air passage side housing facing the hooking portion 7 of the air conditioner body and the top surface side of the main locking piece 8, When the cleaning agent of the heat exchanger or the like is used, there is a problem that the cleaning agent is sprayed directly on the back side of the air conditioner body from the opening of the air passage side housing, and there is a possibility that the wall surface or the like may be soiled.
[0008]
Moreover, since the opening part is provided in the latching | locking part top surface side, there existed a problem that the joining area of the air conditioner main body 1 and the hook part 7 was small, and intensity | strength was weak.
[0009]
The present invention was made to solve the above-described problems, and an opening is provided on the rear surface of the housing without losing the function of preventing the air conditioner body from being detached from the installation plate during pipe connection work. It is an object of the present invention to provide an air conditioner that prevents contamination of a wall surface of a room due to leakage of a heat exchanger cleaning agent.
[0010]
It is another object of the present invention to provide an air conditioner in which an opening is not provided on the top surface side other than the locking portion having a disconnection preventing function and the coupling strength between the air conditioner body and the hook is improved.
[0011]
Moreover, it aims at providing the installation structure to the wall surface of the apparatus which has the function similar to the above.
[0012]
[Means for Solving the Problems]
An air conditioner according to the present invention includes a mounting plate that is installed on a wall surface or the like and has a locking piece, and an air conditioner body that has a hook portion that engages with the locking piece, and the locking piece is normally hooked. If the hook part that engages with the locking piece breaks, including those that do not engage with the part and are not stressed, the locking piece that does not normally engage with the hook part supports the air conditioner body and suppresses falling In the air conditioner, a plurality of locking pieces are provided on the installation plate, and at least one of the locking pieces is a locking piece having a removal prevention function, and is engaged with the locking piece having a removal prevention function.
