【発明の属する技術分野】
本発明は、建物の壁に設けられた貫通穴にエアコン用冷媒管を配管する際に、その貫通穴を覆った状態で、この冷媒管を保護する直状ダクトに接続される保護カバーに関するものである。
【０００２】
【従来の技術】
建物の施工後において、エアコン装置を取付ける場合があり、この場合には、建物の壁を貫通させてエアコン用冷媒管を配管せざるを得ない。そして、冷媒管の空中配管部は、直状ダクト内に収容されることにより、保護されていると共に、室内における美観の低下を防止している。この場合において、建物の壁に設けられた貫通穴は、保護カバーにより覆われる。この保護カバーは、周縁に鍔部を有していて、前記直状ダクトの端部に嵌合状態で接続される。また、エアコン用冷媒管自体は、空中配管されて、直状ダクト内に収容保護されるが、このエアコン用冷媒管は、その貫通穴が設けられている壁と直交する別の壁等の建物構造体に近接して配置されることが、室内美観上好ましい。
【０００３】
上記した従来の保護カバーの一つとして、実開昭５６−１５６３１７号公報に開示されているものが知られている。この保護カバーは、前記貫通穴を覆う鍔部と、前記直状ダクトに嵌合状態で接続される接続口とを備えているが、前記鍔部が前記接続口の全周縁に形成されている。この鍔部の存在により、冷媒管の貫通穴が設けられた壁と直交する別の壁と、冷媒管を収容している直状ダクトとの間に、鍔部の幅に対応する隙間が形成されて、この直状ダクトが空中に浮いた状態となって、該直状ダクトを前記別の壁に当接させることができない。このため、室内の美観が害されると共に、直状ダクトの設置状態も不安定となる。
【０００４】
なお、上記保護カバーの鍔部には、直線状の切断線が設けられて、この切断線で鍔部の一部を切除して、直状ダクトを出来るだけ前記した建物構造体に近接させて配管できるようになっているが、鍔部の一部を切除しても、直状ダクトは前記建物構造体から浮いた状態でしか、その端部において、保護カバーと接続できない。
【０００５】
【発明が解決しようとする課題】
本発明は、エアコン用冷媒管の壁貫通部を保護する保護カバーにおいて、この冷媒管を壁際に配管する際には、これを収容保護する直状ダクトを壁に当接し得るようにして、該直状ダクトを壁に固定可能にし、これにより直状ダクトの設置状態を安定化させると共に、室内の美観の低下を防止することを課題としている。
【０００６】
【課題を解決するための手段】
この課題を解決するための請求項１の発明は、建物の壁に設けられた貫通穴にエアコン用冷媒管を配管する際に、その貫通穴を覆った状態で、前記冷媒管を保護する直状ダクトに嵌合状態で接続される保護カバーであって、前記貫通穴を覆う鍔部と、外壁の一部に壁面に当接する当接面を備えた直状ダクトの外形に対応して該直状ダクトに接続される接続口とを具備していて、前記接続口を分断して分離する二つの分割体の組付けにより構成され、前記分割体が分割される分断線は、直線状であって、しかも前記接続口に接続された直状ダクトの当接面に沿っていて、該接続口の外形の一部を構成する直線部と合致しており、前記接続口の外形は、前記分断線における各分割体の分離により、前記直線部と前記直状ダクトの前記当接面を除く外壁に対応する略コの字形部とに分離され、前記分離により、接続口の外形が略コの字形に分断された一方の分割体は、その開口から、前記壁に直交して設けられる別の壁等の建物構造体に沿って前記当接面が当接する直状ダクトに接続され、前記各分割体を一体に組み付けた状態で、空中配管される前記直状ダクトに接続可能に構成されてなることを特徴としている。
【０００７】
請求項１の発明によれば、壁を貫通して引き出されたエアコン用冷媒管を、該壁と直交する別の壁に近接させて配管する場合には、該冷媒管の壁貫通部を保護するための保護カバーを分断線により二つの分割体に分離すると、接続口の外形が略コの字形に分断された一方の分割体は、その開口から、前記壁に直交して設けられる別の壁等の建物構造体に沿って前記当接面が当接する直状ダクトに接続される。これにより、直状ダクトの当接面を前記建物構造体に当接させて、これに固定することができて、その設置状態が安定化すると共に、該直状ダクトが前記建物構造体に当接して、両者の間に隙間がなくなるため、室内の美観が低下することもない。
【０００８】
また、請求項２の発明は、請求項１の発明において、前記各分割体の背面側には、空中配管させた直状ダクトを接続する際に、前記貫通穴に対して前記各分割体を位置決め状態で仮保持させるための複数のガイド板が設けられているので、各分割体を一体に組み付けた状態で、空中配管される前記直状ダクトに接続する場合に、貫通穴に対する保護カバーを位置決めして仮保持でき、配管作業の作業性が高まる。更に、請求項３の発明は、請求項２の発明において、前記ガイド板は、折取り可能になっているので、接続口の外形が略コの字形に分断された一方の分割体によって、直状ダクトを前記建物構造体に当接させた状態にして、壁の貫通穴を覆う場合には、前記ガイド板は不要であるので、折り取って施工する。
【０００９】
【発明の実施の形態】
以下、実施例を挙げて、本発明を更に詳細に説明する。図１は、直状ダクトＤが室内壁Ｗ3 に当接してエアコン用冷媒管Ｐが壁際に配管された状態の斜視図であり、図２は、同じく平面図であり、図３は、保護カバーＣの部分の拡大斜視図であり、図４は、保護カバーＣの分離状態の斜視図であり、図５は、一体に組付けた状態の保護カバーＣを背面から見た斜視図であり、図６は、図２のＸ−Ｘ線矢視拡大断面図であり、図７は、直状ダクトＤと貫通穴Ｈとの接続部分の縦断面図である。最初に、室内壁Ｗ1 に設けられた貫通穴Ｈを覆った状態で、エアコン用冷媒管（以下、単に「冷媒管」という場合もある）Ｐを保護する直状ダクトＤの端部に嵌合状態で接続される保護カバーＣについて説明する。この保護カバーＣは、図３及び図４に示されるように、上蓋Ｃ1 と下蓋Ｃ2 との２つの分割体を組付けることにより構成されている。上蓋Ｃ1 と下蓋Ｃ2 とは、一体に組付けられた状態において、それらの各鍔部１，２の中央部に直状ダクトＤを内嵌（内側に嵌合させることをいう）させられる接続口３が形成され、該接続口３の周縁部には、上蓋Ｃ1 に形成された略コの字形のダクト分割嵌合部４と、下蓋Ｃ2 に形成された平板状のダクト分割嵌合部５とが、前記各鍔部１，２に対して垂直に形成されている。従って、前記接続口３の外形は、後述の分断線Ｌにより保護カバーＣを上蓋Ｃ 1 と下蓋Ｃ 2 との分離により、上蓋Ｃ 1 の略コの字形の部分と、下蓋Ｃ 2 の直線部とで構成される。各ダクト分割嵌合部４，５は、上蓋Ｃ1 と下蓋Ｃ2 とを一体に組付けた状態において、直状ダクトＤの外形に対応した閉塞形状に組付けられて、各ダクト分割嵌合部４，５によって形成されるダクト嵌合部６の内側に直状ダクトＤが嵌合される。上蓋Ｃ1 及び下蓋Ｃ2 の各鍔部１，２の背面側の周縁部には、補強用のリブ７，８が全周に亘って形成されていると共に、各鍔部１，２の背面側であって、その内部に位置する部分には、同じく補強用のリブ９，１１が垂直に形成されている。下蓋Ｃ2 に設けられた平板状のダクト分割嵌合部５は、平面を保ったままで背面側に延設されて、垂直に設けられた前記リブ１１と直交状態で一体となっている。
【００１０】
上蓋Ｃ1 と下蓋Ｃ2 とは、これらの背面側にそれぞれ一体に設けられた一対の係合爪１２，１３を介して一体に組付けられる。即ち、上蓋Ｃ1 の鍔部１の背面側の下端部における前記接続口３の僅かに内側の部分には、一対の係合爪１２が互いに内側を向いて相対向して一体に設けられている。一方、下蓋Ｃ2 に設けられた板状の前記ダクト分割嵌合部５の背面側に延設された部分であって、しかも上蓋Ｃ1 と下蓋Ｃ2 とを一体に組付けて形成される前記接続口３に臨む部分には、弾性変形可能な一対の係合爪１３が背中合わせとなって設けられている。このため、図４に示されるように、上蓋Ｃ1 と下蓋Ｃ2 とを分離させておいて、これらを互いに近づけると、下蓋Ｃ2 に設けられた一対の係合爪１３が、上蓋Ｃ1 に設けられた一対の係合爪１２の内側に入り込んで、弾性変形された後に原形状に復元することにより、両係合爪１２，１３が互いに係合して、上蓋Ｃ1 と下蓋Ｃ2 とが一体に組付けられる。
【００１１】
また、図４に示されるように、上蓋Ｃ1 の鍔部１の両下端部の前面には、それぞれ嵌合凹部１４が形成されていると共に、下蓋Ｃ2 の前面の両端部には、前記嵌合凹部１４に対して嵌合する板状の嵌合凸部１５が形成され、上蓋Ｃ1 と下蓋Ｃ2 とを一体に組付けると、前記嵌合凹部１４と嵌合凸部１５とは、互いに嵌合して、上蓋Ｃ1 と下蓋Ｃ2 とが一体に組付けられた保護カバーＣの厚さ方向の一体性を保持している。また、上蓋Ｃ1 の鍔部１の前面であって、しかもその外周縁の僅かに内側の部分には、複数のビス下穴１６が設けられていると共に、各ビス下穴１６の背面側には、補強用のリブ７の高さに対応する筒状をしたビス挿通ガイド体１７がそれぞれ設けられている。更に、上蓋Ｃ1 と下蓋Ｃ2 の各鍔部１，２の背面側には、室内壁Ｗ1 に設けられた貫通穴Ｈの内部に挿入されて、該貫通穴Ｈに対して上蓋Ｃ1 、或いは下蓋Ｃ2 を位置決め状態で仮保持させるための円弧板状のガイド板１８がそれぞれ設けられている。このガイド板１８の基端部には、スリット１８ａが幅方向に設けられていて、各鍔部１，２に対する折取りを容易にしている。
【００１２】
最初に、図１に示されるように、前記保護カバーＣを使用して、貫通穴Ｈが設けられた室内壁Ｗ1 及び外壁Ｗ2 の双方に対して直交する別の室内壁Ｗ3 に近接させてエアコン用冷媒管Ｐを配管する場合について説明する。まず、図６に示されるように、室内壁Ｗ1 及び外壁Ｗ2 に対して冷媒管Ｐを貫通配管させるための貫通穴Ｈを設ける。これらの貫通穴Ｈは、各壁Ｗ1,Ｗ2 に対して直交する室内壁Ｗ3 に近接して設けられる。これらの貫通穴Ｈから引き出された冷媒管Ｐは、直状ダクトＤによって保護され、この直状ダクトＤは、冷媒管Ｐを収容可能なベース２１と、該ベース２１に対して係合状態で覆蓋されるカバー体２２とから成る。
【００１３】
そして、室内壁Ｗ1 の内側に取付けられたエアコン装置の室内機２３に接続されている冷媒管Ｐを、該室内壁Ｗ1 に設けられた貫通穴Ｈから引き出した後に、室内壁Ｗ1 と外壁Ｗ2 との間で該冷媒管Ｐを空中配管状態にし、更に外壁Ｗ2 に設けられた貫通穴Ｈから冷媒管Ｐを屋外に引き出す。次に、室内壁Ｗ1 と外壁Ｗ2 との内寸法に等しくなるように前記直状ダクトＤを切断しておいて、両壁Ｗ1,Ｗ2 の間に空中配管されている冷媒管Ｐを前記直状ダクトＤのベース２１に収納して、該ベース２１にカバー体２２を覆蓋させる。このため、図７に示されるように、直状ダクトＤの端面は、前記室内壁Ｗ1 、或いは外壁Ｗ2 に当接した状態となっていて、これらに設けられた貫通穴Ｈ内に入り込むことはない。
【００１４】
最後に、本発明に係る保護カバーＣによって、各貫通穴Ｈの周縁部を覆った状態にする。上記のように、冷媒管Ｐを壁際配管する場合には、保護カバーＣを構成する上蓋Ｃ1 のみを使用する。また、上蓋Ｃ1 のみを使用して、貫通穴Ｈの周縁部を覆う場合には、該上蓋Ｃ1 の背面側に設けられた円弧状のガイド板１８は不要であるので、予め切除しておく。そして、図３，図６及び図７にそれぞれ示されるように、上蓋Ｃ1 の開口側を室内壁Ｗ1 の側に向けて、そのまま直状ダクトＤの外側に嵌め込んだ状態にすると、そのダクト分割嵌合部４の内側に直状ダクトＤの端部が嵌合されて、該上蓋Ｃ1 の端面は、室内壁Ｗ1 に当接する。この状態において、上蓋Ｃ1 の鍔部１に設けられた複数のビス下穴１６の部分からビス２４をねじ込み、複数本のビス２４を介して上蓋Ｃ1 を室内壁Ｗ1 に対して固定すると、貫通穴Ｈの周縁部が該上蓋Ｃ1 によって覆われる。外壁Ｗ2 に設けられた貫通穴Ｈの部分においても、全く同様の施工を行う。これにより、直状ダクトＤを室内壁Ｗ3 に当接させることができるので、上蓋Ｃ1 の施工前において、該直状ダクトＤのベース２１をビス２５を介して室内壁Ｗ3 に固定しておくこともできる（図６参照）。なお、この直状ダクトＤに収納される冷媒管Ｐは、これと一体となって収納されるドレン管Ｐ’内における水溜りを防止するために、外壁Ｗ2 の側が僅かに低くなるようにして配管される。
【００１５】
引き続いて、図８ないし図１２を参照して、貫通穴Ｈが設けられた壁と直交する壁から離れた位置に冷媒管Ｐを空中配管する場合について説明する。この場合には、上記室内壁Ｗ1 と外壁Ｗ2 とに設ける各貫通穴Ｈ’は、直状ダクトＤを挿入できる大きさであって、前記貫通穴Ｈよりも大きい（図９参照）。各貫通穴Ｈ’から引き出されて空中配管された冷媒管Ｐは、直状ダクトＤ内に収容保護されて、該直状ダクトＤの両端部は、各貫通穴Ｈ’に僅かに挿入された状態となる（図１０参照）。なお、施工状態によっては、直状ダクトＤ自体が貫通穴に貫通されることもある。
【００１６】
そして、直状ダクトＤの端部が僅かに挿入された状態となっている貫通穴Ｈ’の周縁部を保護カバーＣで被覆するには、以下のようにして行う。即ち、保護カバーＣを二分割しておいて、直状ダクトＤの端部の上方、及び下方からそれぞれ上蓋Ｃ1 と下蓋Ｃ2 とを該直状ダクトＤの外側に嵌め込んだ状態にして、この上蓋Ｃ1 と下蓋Ｃ2 とに設けられた各係合爪１２，１３を互いに係合させると、両者が一体に組付けられる（図１１参照）。この一体に組付けられた保護カバーＣを貫通穴Ｈ’の側にスライドさせて、その背面側に設けられた円弧状をした複数枚の各ガイド板１８を該貫通穴Ｈ’内に挿入して、上蓋Ｃ1 及び下蓋Ｃ2 の各鍔部１，２の背面側を室内壁Ｗ1 に当接させる（図１２参照）。最後に、上蓋Ｃ1 の鍔部１に設けられた複数のビス下穴１６の部分にビス２４をねじ込み、複数本のビス２４を介して上蓋Ｃ1 を室内壁Ｗ1 に固定する。このように、本発明に係る保護カバーＣは、二分割構造であるために、直状ダクトＤの施工後において、貫通穴Ｈ’の周縁部を保護カバーＣで覆うことができるため、全体としての施工性が向上する。
【００１７】
また、上記実施例の保護カバーＣは、下蓋Ｃ2 を取り外すことにより、保護カバーＣの全体としての鍔部の一部が除去されて、直状ダクトＤを室内壁Ｗ3 に当接可能な構造になっている〔換言すれば、保護カバーＣを二分割する分断線Ｌが接続口３の外形を形成する直線部と合致している（図９参照）〕ため、鍔部を切除することなく、保護カバーＣを二分割するのみで、直状ダクトを上記したように壁際配管することができるために、その施工性が高まると共に、保護カバーの再使用が可能となる利点がある。
【００１８】
【発明の効果】
本発明に係る保護カバーは、上記構成であるので、以下に示される諸効果が奏される。
（１）冷媒管を収容保護する直状ダクトを、貫通穴が設けられた壁と直交する別の壁に当接させた状態で、前記貫通穴を覆うことができる。
（２）このため、直状ダクトを前記別の壁に固定できて、その設置状態が安定化すると共に、直状ダクトと前記別の壁との間に隙間がなくなって、室内の美観が低下することもない。
（３）冷媒管を壁際に配管せず、空中配管する場合には、二分割体を組付けた状態で使用すればよい。この場合には、直状ダクトの施工後において、二つの分割体を組付けて、貫通穴の周縁部を覆うことができるため、施工順序の制約がなくなり、ひいては施工性が高まる。即ち、一種類の保護カバーによって、異なる二種類の配管態様に対して、いずれの壁の貫通穴も覆うことができる。

[0002]
[Prior art]
After the construction of the building, an air conditioner may be installed. In this case, an air conditioner refrigerant pipe must be piped through the building wall. And the aerial piping part of a refrigerant | coolant pipe | tube is protected by being accommodated in a linear duct, and the fall of the aesthetics in a room is prevented. In this case, the through hole provided in the wall of the building is covered with a protective cover. This protective cover has a flange on the periphery, and is connected to the end of the straight duct in a fitted state. The air conditioner refrigerant pipe itself is aerial piped and accommodated and protected in a straight duct. This air conditioner refrigerant pipe is a building such as another wall orthogonal to the wall in which the through hole is provided. It is preferable from the viewpoint of indoor aesthetics to be disposed close to the structure.
[0003]
As one of the conventional protective covers described above, one disclosed in Japanese Utility Model Laid-Open No. 56-156317 is known. The protective cover includes a flange portion that covers the through hole and a connection port that is connected to the straight duct in a fitted state, and the flange portion is formed on the entire periphery of the connection port. . Due to the presence of the flange portion, a gap corresponding to the width of the flange portion is formed between another wall orthogonal to the wall provided with the through hole of the refrigerant tube and the straight duct accommodating the refrigerant tube. Thus, the straight duct is in a floating state in the air, and the straight duct cannot be brought into contact with the other wall. For this reason, the aesthetics of the room is damaged, and the installation state of the straight duct becomes unstable.
[0004]
In addition, a linear cutting line is provided on the collar part of the protective cover, and a part of the collar part is cut off by this cutting line so that the straight duct is as close to the building structure as possible. Although piping is possible, even if a part of the collar is cut off, the straight duct can be connected to the protective cover only at the end thereof in a state where it floats from the building structure.
[0005]
[Problems to be solved by the invention]
The present invention provides a protective cover for protecting a wall through portion of a refrigerant pipe for an air conditioner, and when the refrigerant pipe is piped against the wall, a straight duct for accommodating and protecting the refrigerant pipe can be brought into contact with the wall, An object of the present invention is to make it possible to fix a straight duct to a wall, thereby stabilizing the installation state of the straight duct and preventing a decrease in the appearance of the room.
[0006]
[Means for Solving the Problems]
In order to solve this problem, the invention according to claim 1 is directed to a method for protecting the refrigerant pipe in a state in which the through-hole is covered when the air-conditioner refrigerant pipe is piped in the through-hole provided in the wall of the building. A protective cover connected in a fitted state to the duct, corresponding to the outer shape of the straight duct provided with a flange covering the through-hole and a contact surface abutting against the wall surface at a part of the outer wall A connection port connected to the straight duct, and is configured by assembling two divided bodies that divide and separate the connection port, and the dividing line into which the divided body is divided is linear. And is along the contact surface of the straight duct connected to the connection port, and coincides with a straight line portion constituting a part of the outer shape of the connection port, and the outer shape of the connection port is By separating each of the divided bodies along the dividing line, the straight portion and the contact surface of the straight duct are removed. One of the divided bodies, which are separated into substantially U-shaped portions corresponding to the walls and the outer shape of the connection port is divided into substantially U-shaped parts by the separation, is provided separately from the openings. It is connected to a straight duct with which the abutment surface abuts along a building structure such as a wall, and is configured to be connectable to the straight duct that is piped in the air in a state where the divided bodies are assembled together. It is characterized by.

According to the first aspect of the present invention, when the refrigerant pipe for an air conditioner drawn out through the wall is piped close to another wall orthogonal to the wall, the wall penetration portion of the refrigerant pipe is protected. When the protective cover is separated into two divided parts by a dividing line, the one divided body in which the outer shape of the connection port is divided into a substantially U-shape is separated from the opening by being orthogonal to the wall. It is connected to a straight duct with which the abutment surface abuts along a building structure such as a wall. Accordingly, the contact surface of the straight duct can be brought into contact with and fixed to the building structure , the installation state is stabilized, and the straight duct is brought into contact with the building structure. Since there is no gap between them, the aesthetics of the room is not reduced.
[0008]
Further, the invention of claim 2 is the invention of claim 1, wherein when each of the divided bodies is connected to the through hole, the divided bodies are connected to the back side of the divided bodies. Since a plurality of guide plates are provided for temporary holding in the positioning state, a protective cover for the through hole is provided when connecting to the straight duct that is piped in the air in a state where the divided bodies are assembled together. Positioning and temporary holding are possible, improving the workability of piping work. Further, the invention of claim 3 is that in the invention of claim 2, the guide plate can be broken off, so that the outer shape of the connection port is directly divided by one of the divided bodies. In the state where the duct is brought into contact with the building structure and the through hole of the wall is covered, the guide plate is unnecessary, so it is folded and constructed.
[0009]

Further, on the back side of the flanges 1 and 2 of the upper lid C 1 and the lower lid C 2 , the upper lid C is inserted into the through-hole H provided in the indoor wall W 1. 1 or arcuate plate-like guide plates 18 are provided for temporarily holding the lower lid C 2 in a positioned state. A slit 18a is provided in the width direction at the base end portion of the guide plate 18 so that the flange portions 1 and 2 can be easily broken.
[0012]
First, as shown in FIG. 1, the protective cover C is used to approach another indoor wall W 3 orthogonal to both the indoor wall W 1 and the outer wall W 2 provided with the through hole H. The case where the air conditioner refrigerant pipe P is piped will be described. First, as shown in FIG. 6, a through hole H for allowing the refrigerant pipe P to pass through the indoor wall W 1 and the outer wall W 2 is provided. These through holes H are provided close to the indoor wall W 3 orthogonal to the walls W 1 and W 2 . The refrigerant pipes P drawn from the through holes H are protected by a straight duct D. The straight duct D is engaged with the base 21 and the base 21 that can accommodate the refrigerant pipe P. And a cover body 22 to be covered.
[0013]
Then, the refrigerant pipe P connected to the indoor unit 23 of the air conditioner device mounted on the inside of the chamber wall W 1, after pulled out from the through hole H provided in the chamber inner wall W 1, and the indoor wall W 1 The refrigerant pipe P is brought into an air piping state between the outer wall W 2 and the refrigerant pipe P is drawn out from a through hole H provided in the outer wall W 2 . Next, the keep by cutting the straight duct D to be equal to the inner dimensions of the chamber wall W 1 and the outer wall W 2, the refrigerant pipe P, which is the air pipe between the two walls W 1, W 2 Is stored in the base 21 of the straight duct D, and the cover body 22 is covered with the base 21. For this reason, as shown in FIG. 7, the end face of the straight duct D is in contact with the indoor wall W 1 or the outer wall W 2 and enters the through hole H provided therein. There is nothing.
[0014]
Finally, the protective cover C according to the present invention covers the peripheral edge of each through hole H. As described above, when the refrigerant pipe P is piped near the wall, only the upper lid C 1 constituting the protective cover C is used. When only the upper lid C 1 is used to cover the peripheral edge of the through-hole H, the arc-shaped guide plate 18 provided on the back side of the upper lid C 1 is unnecessary, so that it is cut out in advance. deep. Then, as shown in FIGS. 3, 6, and 7, when the opening side of the upper lid C 1 is directed toward the indoor wall W 1 , and is directly fitted on the outside of the straight duct D, The end portion of the straight duct D is fitted inside the duct division fitting portion 4, and the end surface of the upper lid C 1 comes into contact with the indoor wall W 1 . In this state, screwing screws 24 from the portion of the plurality of screws prepared hole 16 provided in the flange portion 1 of the upper cover C 1, the via a plurality of screws 24 secure the upper cover C 1 to the indoor wall W 1 The periphery of the through hole H is covered with the upper lid C 1 . Also in the portion of the through-hole H provided in the outer wall W 2, performs exactly the same construction. As a result, the straight duct D can be brought into contact with the indoor wall W 3 , so that the base 21 of the straight duct D is fixed to the indoor wall W 3 via the screw 25 before the upper lid C 1 is constructed. (See FIG. 6). It should be noted that the refrigerant pipe P accommodated in the straight duct D is set so that the outer wall W 2 side is slightly lowered in order to prevent water accumulation in the drain pipe P ′ accommodated integrally therewith. Piped.
[0015]
Next, with reference to FIGS. 8 to 12, the case where the refrigerant pipe P is aerial piped at a position away from the wall orthogonal to the wall provided with the through hole H will be described. In this case, each through hole H ′ provided in the indoor wall W 1 and the outer wall W 2 is large enough to insert the straight duct D and is larger than the through hole H (see FIG. 9). The refrigerant pipe P drawn out from each through hole H ′ and piped in the air is accommodated and protected in the straight duct D, and both end portions of the straight duct D are slightly inserted into each through hole H ′. A state is reached (see FIG. 10). In addition, depending on the construction state, the straight duct D itself may penetrate through the through hole.
[0016]
And in order to coat | cover the peripheral part of through-hole H 'in the state where the edge part of the straight duct D was inserted slightly with the protective cover C, it carries out as follows. That is, the protective cover C is divided into two, and the upper lid C 1 and the lower lid C 2 are fitted into the outside of the straight duct D from above and below the end of the straight duct D, respectively. When the engaging claws 12 and 13 provided on the upper lid C 1 and the lower lid C 2 are engaged with each other, they are assembled together (see FIG. 11). The integrally assembled protective cover C is slid toward the through hole H ′, and a plurality of arc-shaped guide plates 18 provided on the back side thereof are inserted into the through hole H ′. Then, the back sides of the flanges 1 and 2 of the upper lid C 1 and the lower lid C 2 are brought into contact with the indoor wall W 1 (see FIG. 12). Finally, screwing the screws 24 in the portion of the plurality of screws prepared hole 16 provided in the flange portion 1 of the upper cover C 1, to fix the upper cover C 1 to chamber wall W 1 via a plurality of screws 24. Thus, since the protective cover C according to the present invention has a two-part structure, since the peripheral edge of the through hole H ′ can be covered with the protective cover C after the construction of the straight duct D, as a whole Improved workability.
[0017]
In addition, the protective cover C of the above embodiment can remove the lower lid C 2 to remove a part of the collar as a whole of the protective cover C, so that the straight duct D can be brought into contact with the indoor wall W 3. [In other words, since the dividing line L that divides the protective cover C into two matches the straight line that forms the outer shape of the connection port 3 (see FIG. 9)], the collar portion is cut out. it not, only bisects the protective cover C, and straight ducts to be able to pipe the wall as described above, together with the workability is increased, there is an advantage that it is possible to re-use of the protective cover.
[0018]
【The invention's effect】
Since the protective cover according to the present invention has the above-described configuration , the following effects are exhibited.
(1) The through hole can be covered in a state in which a straight duct that accommodates and protects the refrigerant pipe is brought into contact with another wall orthogonal to the wall provided with the through hole .
(2) For this reason, the straight duct can be fixed to the other wall, the installation state is stabilized, and there is no gap between the straight duct and the other wall, so that the indoor aesthetics are deteriorated. I don't have to.
(3) If the refrigerant pipe is not piped near the wall but is piped in the air, the refrigerant pipe may be used in an assembled state. In this case, after the construction of the straight duct, the two divided bodies can be assembled to cover the peripheral edge of the through hole, so that the construction sequence is not restricted, and the workability is improved. That is, the through hole of any wall can be covered with two types of different piping modes by one type of protective cover.
