Description

室内機の据付板Indoor unit installation plate
　本開示は、室内の壁に取り付けられる空気調和機における室内機の据付板に関するものである。 This disclosure relates to an indoor unit installation plate in an air conditioner mounted on an indoor wall.
　従来、壁掛型の空気調和機の室内機は、室内の壁に取り付けられた据付板を介して、壁に設置されている。据付板には、室内機から引き出された、屋外に設置された室外機と接続される配管を通すための配管引出用の孔または切り欠きが設けられている。このような孔または切り欠きは、例えば、据付板の下部外周に設けられている（例えば、特許文献１参照）。 Conventionally, the indoor unit of a wall-mounted air conditioner is installed on the wall via an installation plate attached to the wall of the room. The installation plate is provided with a hole or a notch for pipe pulling out from the indoor unit to pass a pipe connected to the outdoor unit installed outdoors. Such a hole or notch is provided, for example, on the lower outer periphery of the installation plate (see, for example, Patent Document 1).
　また、室内機が設置される家屋によっては、室内機と室外機とを接続するための配管が壁の内部に設けられた、所謂埋込配管が設置されている場合がある。このような埋込配管を用いて室内機を室外機と接続する場合、必ずしも室内機の背面側中央部での配管接続を行うことができないため、配管を室内機の外側に引き回す場合がある。この場合には、配管が室内に露出するため、部屋の見栄えが悪化する。そこで、最近では、埋込配管を用いて室内機の背面側での配管接続を行うことができるように、種々の方法が提案されている。 Also, depending on the house where the indoor unit is installed, so-called embedded piping may be installed in which the piping for connecting the indoor unit and the outdoor unit is provided inside the wall. When the indoor unit is connected to the outdoor unit by using such an embedded pipe, the pipe may not always be connected at the center of the back side of the indoor unit, so that the pipe may be routed to the outside of the indoor unit. In this case, the piping is exposed indoors, and the appearance of the room deteriorates. Therefore, recently, various methods have been proposed so that the pipe can be connected on the back side of the indoor unit by using the embedded pipe.
実開平６－２０２２号公報Jikkenhei 6-2022 Gazette
　室内機の背面側での配管接続を行うことができるようにする第１の方法は、種々の配管の形状または位置にも対応できるようにするため、据付板の下部中央近傍に、配管を避けるための切り欠き部を予め大きく形成する方法である。しかしながら、第１の方法では、据付板に対して切り欠き部が過大に形成されるため、据付板の強度が低下してしまう。 The first method to enable piping connection on the back side of the indoor unit is to avoid piping near the center of the lower part of the installation plate so that it can accommodate various pipe shapes or positions. This is a method of forming a large notch for the purpose in advance. However, in the first method, the notch portion is formed excessively with respect to the installation plate, so that the strength of the installation plate is lowered.
　室内機の背面側での配管接続を行うことができるようにする第２の方法は、第１の方法における切り欠き部に代えて、据付板にミシン目状の切り込みを形成する方法である。この場合には、ミシン目状の切り込みに沿って据付板が切断されることにより、室内機の背面側での配管接続を行うことができる。しかしながら、据付板に切り込みが形成されているだけでは、室内機の据付現場で据付板を切断する際に、工具の刃が入りにくいため、作業性が低下してしまう。 The second method of making it possible to connect the pipes on the back side of the indoor unit is a method of forming a perforated notch in the installation plate instead of the notch in the first method. In this case, the installation plate is cut along the perforated notch, so that the piping can be connected on the back side of the indoor unit. However, if only the notch is formed in the installation plate, it is difficult for the blade of the tool to enter when cutting the installation plate at the installation site of the indoor unit, so that the workability is deteriorated.
　本開示は、上記従来の技術における課題に鑑みてなされたものであって、強度を確保しつつ、配管接続作業を容易に行うことができる室内機の据付板を提供することを目的とする。 The present disclosure has been made in view of the above-mentioned problems in the prior art, and an object of the present disclosure is to provide an indoor unit installation plate capable of easily performing piping connection work while ensuring strength.
　本開示の室内機の据付板は、家屋の壁内に設けられた埋込配管を介して、室外機に接続される室内機を前記壁に据え付ける室内機の据付板であって、平板状に形成された本体部と、前記埋込配管を通すように前記本体部に形成された配管接続用孔と、前記配管接続用孔の少なくとも一部に隣接して形成され、前記配管接続用孔を拡大させる切り抜き予備加工が施された領域である孔拡大部とを備えるものである。 The indoor unit installation plate of the present disclosure is an indoor unit installation plate for installing an indoor unit connected to an outdoor unit to the wall via an embedded pipe provided in a wall of a house, and has a flat plate shape. The formed main body portion, the pipe connection hole formed in the main body portion so as to pass the embedded pipe, and the pipe connection hole formed adjacent to at least a part of the pipe connection hole. It is provided with a hole enlargement portion, which is a region that has been subjected to cutout preliminary processing to be enlarged.
　以上のように、本開示によれば、配管接続用孔に隣接して孔拡大部が設けられることにより、埋込配管の種々の形状または位置に対応するように、大きな配管接続用孔を予め設けておく必要がない。そのため、据付板の強度を確保することができる。また、配管接続用孔を拡大したい場合に、孔拡大部を容易に切断して配管接続用孔を拡大させることができるため、配管接続作業を容易に行うことができる。 As described above, according to the present disclosure, by providing the hole enlargement portion adjacent to the pipe connection hole, a large pipe connection hole is previously provided so as to correspond to various shapes or positions of the embedded pipe. There is no need to set it up. Therefore, the strength of the installation plate can be ensured. Further, when it is desired to enlarge the pipe connection hole, the hole expansion portion can be easily cut to enlarge the pipe connection hole, so that the pipe connection work can be easily performed.

FIG. 6 is a front view showing an example of the installation plate of the indoor unit 1 according to the first embodiment. FIG. 7 is an enlarged schematic view showing the periphery of the pipe connection hole of the installation plate of FIG. The installation plate 10 is made of a steel plate and is used when the indoor unit main body 20 is mounted on a wall surface. As shown in FIG. 6, the installation plate 10 includes a main body portion 11 formed in a flat plate shape, a plurality of upper support pieces 12, a plurality of lower fitting holes 13, a pipe connection hole 14, and a hole expansion portion 15. There is.
　上部支持片１２は、本体部１１の上端に設けられ、室内機本体２０の背面上部に設けられた上部嵌合部２７（図８参照）が引っ掛かるように形成されている。上部支持片１２は、例えば、本体部１１の左右近傍と、中央近傍との３箇所に間隔を空けて設けられている。なお、この例において、上部支持片１２は、本体部１１の上端の３箇所に設けられているが、これに限られず、例えば、少なくとも左右の２箇所に設けられていればよい。 The upper support piece 12 is provided at the upper end of the main body portion 11 and is formed so that the upper fitting portion 27 (see FIG. 8) provided at the upper part of the back surface of the indoor unit main body 20 is hooked. The upper support piece 12 is provided at three locations, for example, in the vicinity of the left and right sides of the main body portion 11 and in the vicinity of the center. In this example, the upper support piece 12 is provided at three places at the upper end of the main body portion 11, but is not limited to this, and may be provided at at least two places on the left and right, for example.
　下部嵌合孔１３は、本体部１１の下端に設けられ、室内機本体２０の背面下部に設けられた下部引掛け爪２８（図８参照）が引っ掛かるように形成されている。下部嵌合孔１３は、例えば、本体部１１の左右近傍の２箇所に間隔を空けて設けられている。 The lower fitting hole 13 is provided at the lower end of the main body portion 11 and is formed so that the lower hook claw 28 (see FIG. 8) provided at the lower part of the back surface of the indoor unit main body 20 can be hooked. The lower fitting holes 13 are provided, for example, at two locations near the left and right sides of the main body portion 11 at intervals.
　配管接続用孔１４は、本体部１１における下部の中央近傍に矩形状に設けられている。配管接続用孔１４は、壁面に形成された配管挿通部２００内の埋込配管２０１または室内機本体２０の室内側接続配管のいずれか一方を通し、埋込配管２０１と、据付板１０に取り付けられる室内機本体２０の室内側接続配管とを接続するために設けられている。配管接続用孔１４の外周縁は、曲げ加工されている。より具体的には、配管接続用孔１４には、図７に示すように、外周縁を１８０°折り曲げて密着させた密着曲げ加工部１４ａが形成されている。 The pipe connection hole 14 is provided in a rectangular shape near the center of the lower part of the main body 11. The pipe connection hole 14 is attached to the embedded pipe 201 and the installation plate 10 through either the embedded pipe 201 in the pipe insertion portion 200 formed on the wall surface or the indoor side connection pipe of the indoor unit main body 20. It is provided for connecting to the indoor side connection pipe of the indoor unit main body 20 to be installed. The outer peripheral edge of the pipe connection hole 14 is bent. More specifically, as shown in FIG. 7, the pipe connection hole 14 is formed with a close contact bending portion 14a in which the outer peripheral edge is bent by 180 ° and brought into close contact with the hole 14.
　このように、配管接続用孔１４に密着曲げ加工が施されることにより、配管接続用孔１４のエッジを保護して配管接続用孔１４の安全性を確保することができる。また、密着曲げ加工により、配管接続用孔１４の補強および見栄えをよくする等の効果を奏することもできる。 By performing the close contact bending process on the pipe connection hole 14 in this way, the edge of the pipe connection hole 14 can be protected and the safety of the pipe connection hole 14 can be ensured. Further, the close contact bending process can also have the effect of reinforcing the pipe connecting hole 14 and improving the appearance.
　なお、この例では、配管接続用孔１４が矩形状であるように説明したが、これに限られず、例えば円形状または多角形状でもよい。また、配管接続用孔１４の数は、１つに限られず、据付環境に応じて複数としてもよい。 In this example, the pipe connection hole 14 is described as having a rectangular shape, but the present invention is not limited to this, and may be, for example, a circular shape or a polygonal shape. Further, the number of the pipe connecting holes 14 is not limited to one, and may be a plurality depending on the installation environment.
　図６の孔拡大部１５は、配管接続用孔１４の少なくとも一部に隣接して設けられている。孔拡大部１５は、例えばミシン目状の切り込みで形成された切り抜き予備加工が施された領域であり、切り込みに沿って切断されることにより、配管接続用孔１４を拡大させることができる。 The hole enlargement portion 15 in FIG. 6 is provided adjacent to at least a part of the pipe connection hole 14.

By forming the pipe connection hole 14 in this way, the strength of the installation plate 10 can be ensured.
［室内機本体２０の据付板１０への固定］
　図８は、据付板に対する室内機本体の固定方法について説明するための概略図である。まず、図８に示すように、室内機本体２０の背面上部に設けられた上部嵌合部２７を据付板１０の上部支持片１２に引っ掛ける。次に、上部支持片１２を支点として、室内機本体２０を回転させながら室内機本体２０の下部を据付板１０の方向に押し、室内機本体２０の背面下部に設けられた下部引掛け爪２８を下部嵌合孔１３に引っ掛ける。これにより、室内機本体２０が据付板１０に固定され、室内機１が壁面に据え付けられる。 [Fixing the indoor unit 20 to the installation plate 10]
FIG. 8 is a schematic view for explaining a method of fixing the indoor unit main body to the installation plate. First, as shown in FIG. 8, the upper fitting portion 27 provided on the upper back surface of the indoor unit main body 20 is hooked on the upper support piece 12 of the installation plate 10. Next, with the upper support piece 12 as a fulcrum, the lower portion of the indoor unit main body 20 is pushed toward the installation plate 10 while rotating the indoor unit main body 20, and the lower hook claw 28 provided on the lower back surface of the indoor unit main body 20 is provided. Is hooked on the lower fitting hole 13. As a result, the indoor unit main body 20 is fixed to the installation plate 10, and the indoor unit 1 is installed on the wall surface.
［室内機１の据付］
　図９～図１１は、本実施の形態１に係る室内機の据え付けについて説明するための概略図である。まず、壁内に設けられた配管挿通部２００に埋め込まれた埋込配管２０１が引き出された状態（図９）で、据付板１０の配管接続用孔１４に埋込配管２０１を挿通させながら、据付板１０が壁に設置される（図１０）。次に、設置された据付板１０に対して室内機本体２０が固定され、埋込配管２０１と室内機１の室内側接続配管とが接続される（図１１）。 [Installation of indoor unit 1]
9 to 11 are schematic views for explaining the installation of the indoor unit according to the first embodiment. First, with the embedded pipe 201 embedded in the pipe insertion portion 200 provided in the wall pulled out (FIG. 9), the embedded pipe 201 is inserted into the pipe connection hole 14 of the installation plate 10 while being inserted. The installation plate 10 is installed on the wall (FIG. 10). Next, the indoor unit main body 20 is fixed to the installed installation plate 10, and the embedded pipe 201 and the indoor side connection pipe of the indoor unit 1 are connected (FIG. 11).
　このように、本実施の形態１に係る室内機１の据付板１０には、配管接続用孔１４が予め形成されている。そのため、据え付け現場で据付板１０をカットする等の加工を行うことなく、室内機１の背面側で埋込配管２０１と室内側接続配管とを接続することができる。 As described above, the pipe connection hole 14 is preliminarily formed in the installation plate 10 of the indoor unit 1 according to the first embodiment. Therefore, the embedded pipe 201 and the indoor side connecting pipe can be connected on the back side of the indoor unit 1 without performing processing such as cutting the installation plate 10 at the installation site.
　ここで、埋込配管２０１の引き出し状態に応じて配管接続用孔１４を拡大させる必要がある場合、作業者は、孔拡大部１５のミシン目状の切り込みを切断すればよい。この場合、孔拡大部１５は、配管接続用孔１４に隣接して設けられているため、孔拡大部１５を切断するための工具の刃が入りやすくなっている。したがって、作業者は孔拡大部１５を容易に切断することができる。 Here, when it is necessary to enlarge the pipe connection hole 14 according to the drawer state of the embedded pipe 201, the operator may cut the perforated cut in the hole expansion portion 15. In this case, since the hole expansion portion 15 is provided adjacent to the pipe connection hole 14, it is easy for the blade of the tool for cutting the hole expansion portion 15 to enter. Therefore, the operator can easily cut the hole enlargement portion 15.
　なお、上述した例では、据付板１０に１つの配管接続用孔１４が設けられた場合について説明したが、これに限られず、複数の配管接続用孔１４が設けられてもよい。図１２は、配管接続用孔１４が複数設けられた場合の各配管の接続について説明するための概略図である。この例は、２つの配管接続用孔１４が設けられた場合を示す。 In the above-mentioned example, the case where one pipe connection hole 14 is provided in the installation plate 10 has been described, but the present invention is not limited to this, and a plurality of pipe connection holes 14 may be provided. FIG. 12 is a schematic diagram for explaining the connection of each pipe when a plurality of pipe connection holes 14 are provided. This example shows the case where two pipe connection holes 14 are provided.
　通常、壁内に設けられた配管挿通部２００には、埋込配管２０１として、室内側接続配管に接続される冷媒配管２０１ａと、室内機１で発生したドレン水を室外へ排出するドレン排水用ホース２０１ｂとが挿通されている。そこで、この場合には、一方の配管接続用孔１４に冷媒配管２０１ａを挿通させ、他方の配管接続用孔１４にドレン排水用ホース２０１ｂを挿通させてもよい。すなわち、配管接続用孔１４は、埋込配管２０１が異なる複数の用途に用いられる複数の配管で構成されている場合に、それぞれの配管に対応するように、複数形成されてもよい。 Normally, in the pipe insertion portion 200 provided in the wall, as the embedded pipe 201, the refrigerant pipe 201a connected to the indoor side connection pipe and the drain water for draining the drain water generated in the indoor unit 1 to the outside are discharged. The hose 201b is inserted. Therefore, in this case, the refrigerant pipe 201a may be inserted into one pipe connection hole 14, and the drain drain hose 201b may be inserted into the other pipe connection hole 14. That is, when the embedded pipe 201 is composed of a plurality of pipes used for a plurality of different uses, a plurality of pipe connection holes 14 may be formed so as to correspond to the respective pipes.
　以上のように、本実施の形態１に係る室内機１の据付板１０は、埋込配管２０１を通すように本体部１１に形成された配管接続用孔１４と、配管接続用孔１４に隣接して形成され、配管接続用孔１４を拡大させる孔拡大部１５とを備える。このように、配管接続用孔１４に隣接する孔拡大部１５が据付板１０に設けられることにより、埋込配管２０１の種々の形状または位置に対応するように、大きな配管接続用孔１４を予め設けておく必要がない。そのため、据付板１０の強度を確保することができる。 As described above, the installation plate 10 of the indoor unit 1 according to the first embodiment is adjacent to the pipe connection hole 14 formed in the main body 11 so as to pass the embedded pipe 201 and the pipe connection hole 14. It is provided with a hole expansion portion 15 for expanding the pipe connection hole 14. In this way, by providing the hole enlargement portion 15 adjacent to the pipe connection hole 14 in the installation plate 10, a large pipe connection hole 14 is previously provided so as to correspond to various shapes or positions of the embedded pipe 201. There is no need to set it up. Therefore, the strength of the installation plate 10 can be ensured.
　また、孔拡大部１５が配管接続用孔１４に隣接するため、埋込配管２０１の形状または位置に応じて配管接続用孔１４を拡大させたい場合に、孔拡大部１５を容易に切断することができ、それによって配管接続用孔１４を容易に拡大させることができる。そのため、配管接続作業の際の作業性を向上させることができる。 Further, since the hole expansion portion 15 is adjacent to the pipe connection hole 14, the hole expansion portion 15 can be easily cut when it is desired to expand the pipe connection hole 14 according to the shape or position of the embedded pipe 201. This allows the pipe connection hole 14 to be easily expanded. Therefore, workability at the time of pipe connection work can be improved.
　室内機１の据付板１０において、孔拡大部１５は、ミシン目状の切り込みで形成されている。これにより、配管接続用孔１４を拡大させる場合に、配管接続用孔１４を利用して作業者の工具が入りやすくなるため、孔拡大部１５を容易に切断することができる。 In the installation plate 10 of the indoor unit 1, the hole expansion portion 15 is formed by a perforated notch. As a result, when the pipe connection hole 14 is expanded, the operator's tool can easily enter the pipe connection hole 14, so that the hole expansion portion 15 can be easily cut.
　室内機１の据付板１０において、配管接続用孔１４は、外周に、１８０°折り曲げて密着させた密着曲げ加工部１４ａが形成されている。これにより、配管接続用孔１４のエッジが保護されるため、配管接続用孔１４の安全性を確保することができる。 In the installation plate 10 of the indoor unit 1, the pipe connection hole 14 is formed with a close contact bending portion 14a that is bent 180 ° and brought into close contact with the outer periphery. As a result, the edge of the pipe connection hole 14 is protected, so that the safety of the pipe connection hole 14 can be ensured.
