Description

本発明は、外郭を形成する筐体に設けられた開口部を開閉自在に塞ぐサービスパネルを備えた空気調和機の室外機に関するものである。 The present invention relates to an outdoor unit of an air conditioner provided with a service panel for opening and closing an opening provided in a housing forming an outer shell.

従来、空気調和機の室外機は、外郭を形成する筐体を有した空気調和機本体と、筐体に設けられた開口部を覆うサービスパネルと、を備えた構成が知られている。サービスパネルは、空気調和機本体の内部を点検等する際に取り外され、作業が終了するまで、一時的に他の場所に仮置きされる。例えば、室外機が同一箇所に多数設置されている場合、又は室外機が狭小な場所に設置されている場合等においては、取り外したサービスパネルの置き場所に困る事態が発生していた。特に、同一機種の室外機が多数設置されている場合においては、取り外して同一場所に仮置きしたサービスパネルが混同し、他の室外機に異なるサービスパネルを取り付けてしまう事態が想定される。サービスパネルには、製造番号及び現地での追加冷媒量等の重要な製品情報が記載されている。そのため、サービスパネルを取り違えてしまうと、空気調和機本体の情報とサービスパネルの情報とが一致しなくなり、製造号機の不一致又は追加冷媒情報の不一致等の問題が生じ、故障或いは事故の原因に繋がる虞がある。また、仮置きしたサービスパネルによって作業者の作業スペースが制限され、作業性が低下する虞もあった。 Conventionally, an outdoor unit of an air conditioner is known to have a configuration including an air conditioner main body having a housing forming an outer shell and a service panel covering an opening provided in the housing. The service panel is removed when inspecting the inside of the main body of the air conditioner, and is temporarily placed in another place until the work is completed. For example, when a large number of outdoor units are installed in the same place, or when the outdoor units are installed in a narrow place, there is a problem in the place where the removed service panel is placed. In particular, when many outdoor units of the same model are installed, it is assumed that the service panels that have been removed and temporarily placed in the same place may be confused and different service panels may be attached to other outdoor units. The service panel contains important product information such as the serial number and the amount of additional refrigerant on site. Therefore, if the service panel is mistaken, the information of the air conditioner main body and the information of the service panel will not match, causing problems such as mismatch of the manufacturing unit or mismatch of additional refrigerant information, which may lead to a failure or an accident. There is a risk. In addition, the temporarily placed service panel limits the work space of the worker, which may reduce workability.

例えば特許文献１に開示された空気調和機では、空気調和機本体の開口部を開閉自在に覆う下部前面パネルが設けられた構成である。下部前面パネルは、一端がヒンジ機構部によって、空気調和機本体に開閉自在に支持されている。下部前面パネルは、ヒンジ機構部を軸に回動自在に構成されている。 For example, the air conditioner disclosed in Patent Document 1 has a configuration in which a lower front panel is provided to openably cover the opening of the main body of the air conditioner. One end of the lower front panel is supported by a hinge mechanism so that it can be opened and closed by the air conditioner body. The lower front panel is configured to be rotatable around the hinge mechanism portion.

本実施の形態に係る空気調和機の室外機１００は、図１及び図２に示すように、外郭を形成する筐体１０を有する空気調和機本体１と、筐体１０に設けられた開口部１１をヒンジ機構部３によって開閉自在に覆うサービスパネル２と、を備えている。 As shown in FIGS. 1 and 2, the outdoor unit 100 of the air conditioner according to the present embodiment has an air conditioner main body 1 having a housing 10 forming an outer shell and an opening provided in the housing 10. A service panel 2 that covers the 11 11 with a hinge mechanism 3 so as to be openable and closable is provided.

筐体１０は、一例として前側面パネル１０ａ、底面パネル１０ｂ、天面パネル１０ｃ、及び背面パネル１０ｄで構成されている。前側面パネル１０ａは、筐体１０の前面側の一部と左側面側を構成するものであり、例えばＬ字形状の鋼製部材で構成されている。前側面パネル１０ａには、円形状の吹出口が形成されており、吹出口を覆うファンガード１２が取り付けられている。背面パネル１０ｄは、右側面側の一部と背面側を構成するものであり、例えばＬ字形状の鋼製部材で構成されている。前側面パネル１０ａの前面側と、背面パネル１０ｄの右側面側との間には、開口部１１が設けられており、該開口部１１がサービスパネル２で覆われている。この開口部１１は、空気調和機本体１の内部を点検等するために設けられている。空気調和機の室外機１００は、底面パネル１０ｂの下面に取り付けられた脚部１３を設置場所に固定して設置される。 As an example, the housing 10 is composed of a front side panel 10a, a bottom panel 10b, a top panel 10c, and a back panel 10d. The front side panel 10a constitutes a part of the front side and the left side of the housing 10, and is made of, for example, an L-shaped steel member. A circular air outlet is formed on the front side surface panel 10a, and a fan guard 12 covering the air outlet is attached. The back panel 10d constitutes a part of the right side and the back side, and is made of, for example, an L-shaped steel member. An opening 11 is provided between the front side of the front side panel 10a and the right side of the back panel 10d, and the opening 11 is covered with the service panel 2. The opening 11 is provided for inspecting the inside of the air conditioner main body 1. The outdoor unit 100 of the air conditioner is installed by fixing the legs 13 attached to the lower surface of the bottom panel 10b to the installation location.

なお、詳細に図示することは省略したが、筐体１０の内部には、例えば圧縮機、室外熱交換器、減圧装置、室外ファン及びファンモータ等が設けられている。圧縮機は、吸入した低圧冷媒を圧縮し、高圧冷媒として吐出する流体機械である。圧縮機としては、例えば、回転速度を調整自在なインバータ駆動の密閉型電動圧縮機などが用いられる。室外熱交換器は、冷房運転時には放熱器（例えば、凝縮器）として機能し、暖房運転時には蒸発器として機能する熱交換器である。減圧装置は、高圧冷媒を減圧して低圧冷媒とするものである。減圧装置としては、例えば開度を調節自在な電子膨張弁などが用いられる。 Although not shown in detail, for example, a compressor, an outdoor heat exchanger, a decompression device, an outdoor fan, a fan motor, and the like are provided inside the housing 10. The compressor is a fluid machine that compresses the sucked low-pressure refrigerant and discharges it as the high-pressure refrigerant. As the compressor, for example, an inverter-driven sealed electric compressor whose rotation speed can be adjusted is used. The outdoor heat exchanger is a heat exchanger that functions as a radiator (for example, a condenser) during a cooling operation and as an evaporator during a heating operation. The decompression device decompresses the high-pressure refrigerant into a low-pressure refrigerant. As the pressure reducing device, for example, an electronic expansion valve whose opening degree can be adjusted is used.

室外ファンは、例えば、プロペラファンで構成される送風手段である。室外ファンは、筐体１０の背面側から筐体１０の内部に外気を導入し、筐体１０の内部に導入された外気を筐体１０の前面側に向かって排出する機能を有する。室外ファンモータは、室外ファンを駆動する駆動手段である。 The outdoor fan is, for example, a blowing means composed of a propeller fan. The outdoor fan has a function of introducing outside air into the housing 10 from the back side of the housing 10 and discharging the outside air introduced inside the housing 10 toward the front side of the housing 10. The outdoor fan motor is a driving means for driving the outdoor fan.

サービスパネル２は、図１〜図３に示すように、筐体１０の開口部１１を覆うようにＬ字状の鋼製部材で構成されている。サービスパネル２は、Ｌ字の一方の面が筐体１０の前側面の一部を構成し、Ｌ字の他方の面が筐体１０の右側面の一部を構成している。サービスパネル２は、筐体１０の前側面パネル１０ａにネジ等の接合部材で接合されており、空気調和機本体１の内部の点検等が行われる場合に接合部材が取り外され、図２に示すように、ヒンジ機構部３を介して回動される。なお、サービスパネル２には、重要な製品情報が記載されている。製品情報とは、例えば電気配線図、冷媒回路図、製造番号及び現地での追加冷媒量等である。 As shown in FIGS. 1 to 3, the service panel 2 is made of an L-shaped steel member so as to cover the opening 11 of the housing 10. In the service panel 2, one surface of the L-shape constitutes a part of the front side surface of the housing 10, and the other side of the L-shape forms a part of the right side surface of the housing 10. The service panel 2 is joined to the front side panel 10a of the housing 10 by a joining member such as a screw, and the joining member is removed when the inside of the air conditioner main body 1 is inspected, and is shown in FIG. As described above, it is rotated via the hinge mechanism portion 3. In addition, important product information is described in the service panel 2. The product information is, for example, an electric wiring diagram, a refrigerant circuit diagram, a serial number, an amount of additional refrigerant in the field, and the like.

ヒンジ機構部３は、図１及び図３に示すように、空気調和機本体１に設けられた筒状のヒンジ部４と、サービスパネル２に設けられ、ヒンジ部４に着脱自在に差し込まれる爪部５と、で構成されている。 As shown in FIGS. 1 and 3, the hinge mechanism portion 3 has a tubular hinge portion 4 provided in the air conditioner main body 1 and a claw provided in the service panel 2 and detachably inserted into the hinge portion 4. It is composed of a part 5.

ヒンジ部４は、図４に示すように、円筒状の鋼製部材であり、上面に開口４１を有している。ヒンジ部４は、図１に示すように、背面パネル１０ｄの右側面側において、筐体１０の上下方向に沿って２つ設けられている。但し、ヒンジ部４を設ける位置及び個数は、図示した構成に限定されない。ヒンジ部４は、筐体１０の前後方向に設けてもよいし、１個又は３個以上設けてもよい。つまり、ヒンジ部４は、空気調和機本体１の大きさ又は形状に応じて適宜変更して設けるものとする。 As shown in FIG. 4, the hinge portion 4 is a cylindrical steel member and has an opening 41 on the upper surface. As shown in FIG. 1, two hinge portions 4 are provided on the right side surface side of the back panel 10d along the vertical direction of the housing 10. However, the position and number of hinge portions 4 are not limited to the illustrated configuration. The hinge portions 4 may be provided in the front-rear direction of the housing 10, or may be provided one or three or more. That is, the hinge portion 4 is appropriately modified and provided according to the size or shape of the air conditioner main body 1.

また、ヒンジ部４は、背面パネル１０ｄに設ける構成に限定されない。室外機１００の構造によっては、背面パネル１０ｄを有しない場合がある。そのような場合には、例えば空気調和機本体１に上下方向に延びる板材を設け、該板材にヒンジ部４を取り付けたり、筐体１０の内部に配置した構成部材を利用してヒンジ部４を取り付けたりしてもよい。また、図示することは省略したが、ヒンジ部４は、外部から見えないように筐体１０の内側に設けてもよい。 Further, the hinge portion 4 is not limited to the configuration provided on the back panel 10d. Depending on the structure of the outdoor unit 100, the back panel 10d may not be provided.

It may be attached. Further, although not shown, the hinge portion 4 may be provided inside the housing 10 so as not to be seen from the outside.

ヒンジ部４には、図４に示すように、ヒンジ部４に嵌め込まれた爪部５を軸に回動自在に構成されたサービスパネル２が目標の位置まで回動すると爪部５の動きを規制する切り欠き部４０が形成されている。切り欠き部４０は、一例として、上端縁から下方に向かって矩形状に切り欠いた形状であり、サービスパネル２が目標の位置まで回動した位置に形成されている。 As shown in FIG. 4, the hinge portion 4 moves the claw portion 5 when the service panel 2 rotatably configured around the claw portion 5 fitted in the hinge portion 4 rotates to a target position. A notch 40 for regulation is formed. As an example, the cutout portion 40 has a rectangular shape cut out from the upper end edge downward, and is formed at a position where the service panel 2 is rotated to a target position.

図５及び図６は、本発明の実施の形態１に係る空気調和機の室外機のヒンジ部の異なる形態を示した説明図である。切り欠き部４０は、図５に示すように、上端縁から下方に向かって三角形状に切り欠いた形状としてもよい。或いは、切り欠き部４０は、図６に示すように、下端部が円弧状となるように切り欠いた形状としてもよい。切り欠き部４０は、図５に示す三角形状又は図６に示す下端部が円弧状とすることで、爪部５をきっちりと位置決めさせて嵌め込むことができ、爪部５と切り欠き部４０との隙間によって生じるガタつきを防止することができる。 5 and 6 are explanatory views showing different forms of the hinge portion of the outdoor unit of the air conditioner according to the first embodiment of the present invention. As shown in FIG. 5, the cutout portion 40 may have a shape cut out in a triangular shape downward from the upper end edge. Alternatively, as shown in FIG. 6, the cutout portion 40 may have a shape cut out so that the lower end portion has an arc shape. The notch portion 40 has a triangular shape shown in FIG. 5 or an arc shape at the lower end portion shown in FIG. 6, so that the claw portion 5 can be accurately positioned and fitted, and the claw portion 5 and the notch portion 40 can be fitted. It is possible to prevent rattling caused by the gap between the two.

爪部５は、図１及び図３に示すように、回動部５０と挿入部５１とを有する下向きＬ字状で構成され、サービスパネル２の右側面側の縦縁部に設けられている。回動部５０は、ヒンジ部４に向かって突き出し、図２及び図４に示すように、サービスパネル２が目標の位置まで回動すると切り欠き部４０に嵌め込まれて動きが規制されるものである。挿入部５１は、回動部５０の一端に形成されてヒンジ部４の筒内に着脱自在に嵌め込まれるものである。 As shown in FIGS. 1 and 3, the claw portion 5 is formed in a downward L-shape having a rotating portion 50 and an insertion portion 51, and is provided on a vertical edge portion on the right side surface side of the service panel 2. .. The rotating portion 50 protrudes toward the hinge portion 4, and as shown in FIGS. 2 and 4, when the service panel 2 rotates to the target position, the rotating portion 50 is fitted into the notch portion 40 and its movement is restricted. is there. The insertion portion 51 is formed at one end of the rotating portion 50 and is detachably fitted into the cylinder of the hinge portion 4.

上記したように、実施の形態１に係る空気調和機の室外機１００では、サービスパネル２が、ヒンジ部４に嵌め込まれた爪部５を軸に回動自在に構成されている。したがって、空気調和機の室外機１００は、空気調和機本体１からサービスパネル２を取り外すことなく開口部１１を開口させることができるので、空気調和機本体１の内部を点検等する際に、サービスパネル２を取り外して一時的に他の場所に仮置きする必要がない。つまり、空気調和機の室外機１００は、同一機種の室外機が多数設置されている場合であっても、サービスパネル２を取り違えることがない。その上、サービスパネル２によって作業者の作業スペースが制限されることもないから、作業効率の向上に寄与することができる。 As described above, in the outdoor unit 100 of the air conditioner according to the first embodiment, the service panel 2 is configured to be rotatable around the claw portion 5 fitted in the hinge portion 4. Therefore, the outdoor unit 100 of the air conditioner can open the opening 11 without removing the service panel 2 from the air conditioner main body 1, so that when inspecting the inside of the air conditioner main body 1, a service is provided. There is no need to remove the panel 2 and temporarily place it in another place. That is, the outdoor unit 100 of the air conditioner does not mistake the service panel 2 even when many outdoor units of the same model are installed. Moreover, since the work space of the worker is not limited by the service panel 2, it is possible to contribute to the improvement of work efficiency.

また、実施の形態１に係る空気調和機の室外機１００は、ヒンジ部４に嵌め込まれた爪部５を軸に回動自在に構成されたサービスパネル２が目標の位置まで回動すると爪部５の動きを規制する切り欠き部４０がヒンジ部４に形成されているので、回動させたサービスパネル２を目標の位置で固定させることができる。よって、空気調和機の室外機１００は、回動させたサービスパネル２が作業者の邪魔になることがないし、サービスパネル２に記載された重要な製品情報を確認しながら作業を行うことができるので、作業効率を高めることができる。 Further, in the outdoor unit 100 of the air conditioner according to the first embodiment, when the service panel 2 rotatably configured around the claw portion 5 fitted in the hinge portion 4 rotates to the target position, the claw portion Since the notch portion 40 that regulates the movement of the 5 is formed in the hinge portion 4, the rotated service panel 2 can be fixed at the target position. Therefore, in the outdoor unit 100 of the air conditioner, the rotated service panel 2 does not interfere with the operator, and the work can be performed while checking the important product information described on the service panel 2. Therefore, work efficiency can be improved.

また、爪部５は、サービスパネル２からヒンジ部４に向かって突き出し、サービスパネル２が目標の位置まで回動すると切り欠き部４０に嵌め込まれて動きが規制される回動部５０と、回動部５０の一端に形成されてヒンジ部４の筒内に着脱自在に嵌め込まれる挿入部５１と、を有した構成である。つまり、実施の形態１の空気調和機の室外機１００は、ヒンジ機構部３を簡易な構造で構成したので、製造コストの削減に寄与することができる。 Further, the claw portion 5 protrudes from the service panel 2 toward the hinge portion 4, and when the service panel 2 rotates to the target position, the claw portion 5 is fitted into the notch portion 40 and the movement is restricted.
