Description

ヒートポンプサイクル装置の室外機、及び、ヒートポンプサイクル装置Outdoor unit of heat pump cycle device, and heat pump cycle device
　本発明は、筐体の外部に空気を吹き出す吹出口を覆うファンガードを備えたヒートポンプサイクル装置の室外機、及び、ヒートポンプサイクル装置に関する。 The present invention relates to an outdoor unit of a heat pump cycle device equipped with a fan guard that covers an outlet that blows air out of a housing, and to a heat pump cycle device.
　一般に、ヒートポンプサイクル装置の室外機は、熱交換器やファンなどを格納する筐体と、この筐体の内部に配置される熱交換器で冷媒と熱交換を行った空気を筐体外部に吹き出すための吹出口を覆うファンガードとを有する。この種の室外機では、ファンガードは、人がファンに直接手を触れないような形状、大きさとされ、ねじ止めなどの手段で筐体のパネルに取り付けられている（例えば、特許文献１参照）。 Generally, the outdoor unit of a heat pump cycle device has a housing that houses a heat exchanger, a fan, etc., and a fan guard that covers an outlet through which air that has exchanged heat with a refrigerant in the heat exchanger located inside the housing is blown out to the outside of the housing. In this type of outdoor unit, the fan guard is shaped and sized to prevent people from directly touching the fan, and is attached to the panel of the housing by means of screws or other means (see, for example, Patent Document 1).

　ところで、近年、ヒートポンプサイクル装置は高い省エネ性も求められることから従来の室外機よりも伝熱面積を増加させるために熱交換器が大型化しており、これに伴い室外機の吹出口やファンガードも大型化される傾向にある。ファンガードは、大型化に伴い重量も増加するため、ファンガード自体が取り扱い難くなる。このため、従来のようにファンガードをねじで筐体のパネルに取り付ける際に、ファンガードの取付孔とパネルのねじ孔とが位置ずれを起こすなど、ファンガードの取り付け作業の困難性が増すといった問題があった。 In recent years, heat pump cycle devices have been required to be highly energy efficient, so heat exchangers have become larger to increase the heat transfer area compared to conventional outdoor units. As a result, the air outlets and fan guards of outdoor units have also tended to become larger. As the fan guard becomes larger, its weight also increases, making the fan guard itself difficult to handle. This has led to problems when attaching the fan guard to the housing panel with screws, such as misalignment of the fan guard mounting holes and the panel screw holes, making the fan guard installation process more difficult.
　開示の技術は、上記に鑑みてなされたものであって、筐体のパネルに大型化されたファンガードを取り付ける際の作業性を改善できるヒートポンプサイクル装置の室外機、及び、ヒートポンプサイクル装置を提供することを目的とする。 The disclosed technology has been developed in consideration of the above, and aims to provide an outdoor unit for a heat pump cycle device that can improve the ease of installation of a large fan guard on a housing panel, and a heat pump cycle device.

Fig. 1 is a circuit diagram showing an example of a refrigerant circuit and a water circuit of a heat pump cycle device according to this embodiment. The heat pump cycle device 1 includes an outdoor unit 2 and an indoor unit 3, which are connected to each other by water piping to form a water circuit 4. The heat pump cycle device 1 cools or heats a room (space) in which the indoor unit 3 is located by circulating cold water or hot water through the water circuit 4 of the outdoor unit 2 and the indoor unit 3. Note that, although Fig. 1 illustrates an example of the heat pump cycle device 1 including one indoor unit 3, the heat pump cycle device 1 may include a plurality of indoor units 3 connected in parallel to the outdoor unit 2.
　図１に示すように、室外機２は、圧縮機１１と、四方弁１２と、室外熱交換器（熱交換器）１３と、室外膨張弁１４と、水冷媒熱交換器１５と、アキュムレータ１６と、室外ファン（ファン）１７とを有する。これら圧縮機１１、四方弁１２、室外熱交換器１３、室外膨張弁１４、水冷媒熱交換器１５及びアキュムレータ１６は、それぞれ冷媒配管１８により接続されて冷媒回路１０を形成する。この冷媒回路１０は、室外機２の内部で完結して冷凍サイクルを構成する。また、水冷媒熱交換器１５には、冷媒配管１８とは別に水配管１９が接続されている。この水配管１９は、室外機２の外部に延びて室内機３の室内ユニット２３（後述する）に接続されて水回路４を形成する。 As shown in FIG. 1, the outdoor unit 2 has a compressor 11, a four-way valve 12, an outdoor heat exchanger (heat exchanger) 13, an outdoor expansion valve 14, a water-refrigerant heat exchanger 15, an accumulator 16, and an outdoor fan (fan) 17. The compressor 11, the four-way valve 12, the outdoor heat exchanger 13, the outdoor expansion valve 14, the water-refrigerant heat exchanger 15, and the accumulator 16 are connected by refrigerant piping 18 to form a refrigerant circuit 10. This refrigerant circuit 10 is completed inside the outdoor unit 2 to form a refrigeration cycle. In addition, a water piping 19 is connected to the water-refrigerant heat exchanger 15 in addition to the refrigerant piping 18. This water piping 19 extends outside the outdoor unit 2 and is connected to an indoor unit 23 (described later) of the indoor unit 3 to form the water circuit 4.
　圧縮機１１は、例えば、運転容量を変更できる高圧容器型の能力可変型圧縮機であり、吸入した低圧のガス冷媒を圧縮して高圧のガス冷媒を吐出する。圧縮機１１の冷媒吐出側には四方弁１２が接続され、冷媒吸入側にはアキュムレータ１６が接続されている。 The compressor 11 is, for example, a high-pressure container type variable capacity compressor that can change its operating capacity, compresses the low-pressure gas refrigerant it draws in, and discharges high-pressure gas refrigerant. A four-way valve 12 is connected to the refrigerant discharge side of the compressor 11, and an accumulator 16 is connected to the refrigerant suction side.
　四方弁１２は、冷媒回路１０における冷媒の流れる方向を切替えるための弁であり、第１のポート１２Ａ～第４のポート１２Ｄを備えている。第１のポート１２Ａは、圧縮機１１の冷媒吐出側と接続されている。第２のポート１２Ｂは、室外熱交換器１３の一方の冷媒出入口１３Ａと接続されている。第３のポート１２Ｃは、アキュムレータ１６の冷媒流入側と接続されている。そして、第４のポート１２Ｄは、水冷媒熱交換器１５の一方の冷媒出入口１５Ａと接続されている。 The four-way valve 12 is a valve for switching the direction of refrigerant flow in the refrigerant circuit 10, and has a first port 12A to a fourth port 12D. The first port 12A is connected to the refrigerant discharge side of the compressor 11. The second port 12B is connected to one of the refrigerant inlets 13A of the outdoor heat exchanger 13. The third port 12C is connected to the refrigerant inlet side of the accumulator 16. And the fourth port 12D is connected to one of the refrigerant inlets 15A of the water-refrigerant heat exchanger 15.
　室外熱交換器１３は、例えば、フィンチューブ熱交換器が用いられる。室外熱交換器１３は、冷媒と室外ファン１７の回転により室外機２の内部に取り込まれた外気とを熱交換させる。室外熱交換器１３の他方の冷媒出入口１３Ｂは、室外膨張弁１４を介して、水冷媒熱交換器１５の他方の冷媒出入口１５Ｂと接続されている。室外熱交換器１３は、ヒートポンプサイクル装置１が冷房運転を行う場合に凝縮器として機能して、ガス冷媒を凝縮（液化）させる。また、室外熱交換器１３は、ヒートポンプサイクル装置１が暖房運転を行う場合に蒸発器として機能して、液冷媒を蒸発（気化）させる。 The outdoor heat exchanger 13 may be, for example, a fin tube heat exchanger. The outdoor heat exchanger 13 exchanges heat between the refrigerant and the outside air taken into the outdoor unit 2 by the rotation of the outdoor fan 17. The other refrigerant inlet/outlet 13B of the outdoor heat exchanger 13 is connected to the other refrigerant inlet/outlet 15B of the water-refrigerant heat exchanger 15 via the outdoor expansion valve 14. When the heat pump cycle device 1 is performing cooling operation, the outdoor heat exchanger 13 functions as a condenser to condense (liquefy) the gas refrigerant. When the heat pump cycle device 1 is performing heating operation, the outdoor heat exchanger 13 functions as an evaporator to evaporate (vaporize) the liquid refrigerant.
　室外膨張弁１４は、室外熱交換器１３の他方の冷媒出入口１３Ｂと水冷媒熱交換器１５の他方の冷媒出入口１５Ｂとの間に設けられている。室外膨張弁１４は、例えば電子膨張弁であり、弁開度を調整することで、室外膨張弁１４を通過する液冷媒を減圧（膨張）する。 The outdoor expansion valve 14 is provided between the other refrigerant inlet/outlet 13B of the outdoor heat exchanger 13 and the other refrigerant inlet/outlet 15B of the water-refrigerant heat exchanger 15. The outdoor expansion valve 14 is, for example, an electronic expansion valve, and reduces the pressure (expands) of the liquid refrigerant passing through the outdoor expansion valve 14 by adjusting the valve opening.
　水冷媒熱交換器１５は、例えばプレート熱交換器が用いられる。水冷媒熱交換器１５は、冷媒回路１０を循環する冷媒と水回路４を循環する水とを熱交換する。水冷媒熱交換器１５は、ヒートポンプサイクル装置１が冷房運転や除霜運転を行う場合に蒸発器として機能して、液冷媒を蒸発（気化）させる。また、水冷媒熱交換器１５は、ヒートポンプサイクル装置１が暖房運転を行う場合に凝縮器として機能して、ガス冷媒を凝縮（液化）させる。水冷媒熱交換器１５は、水入口１５Ｃと水出口１５Ｄとを有し、これら水入口１５Ｃと水出口１５Ｄにそれぞれ水配管１９が接続されて水回路４の一部を構成する。また、例えば、水入口１５Ｃ側には、水回路４に水を循環させる循環ポンプ２１が設けられ、水出口１５Ｄ側には、水回路４内に進入した空気を抜くための空気抜き弁２２が設けられる。 The water-refrigerant heat exchanger 15 may be, for example, a plate heat exchanger. The water-refrigerant heat exchanger 15 exchanges heat between the refrigerant circulating through the refrigerant circuit 10 and the water circulating through the water circuit 4. When the heat pump cycle device 1 is in cooling or defrosting operation, the water-refrigerant heat exchanger 15 functions as an evaporator to evaporate (vaporize) the liquid refrigerant. When the heat pump cycle device 1 is in heating operation, the water-refrigerant heat exchanger 15 functions as a condenser to condense (liquefy) the gas refrigerant. The water-refrigerant heat exchanger 15 has a water inlet 15C and a water outlet 15D, and water pipes 19 are connected to the water inlet 15C and the water outlet 15D, respectively, to form a part of the water circuit 4. For example, a circulation pump 21 for circulating water through the water circuit 4 is provided on the water inlet 15C side, and an air vent valve 22 for venting air that has entered the water circuit 4 is provided on the water outlet 15D side.
　アキュムレータ１６の冷媒流入側は、四方弁１２の第３のポート１２Ｃと接続され、冷媒流出側は圧縮機１１の冷媒流入側と接続される。アキュムレータ１６は、中空の圧力容器として形成され、内部に流入した冷媒をガス冷媒と液冷媒とに分離して、ガス冷媒のみを圧縮機１１に吸入させる。 The refrigerant inlet side of the accumulator 16 is connected to the third port 12C of the four-way valve 12, and the refrigerant outlet side is connected to the refrigerant inlet side of the compressor 11. The accumulator 16 is formed as a hollow pressure vessel, and separates the refrigerant that flows into it into gas refrigerant and liquid refrigerant, allowing only the gas refrigerant to be sucked into the compressor 11.
　室外ファン１７は、室外熱交換器１３の近傍に配置され、該室外熱交換器１３に向けて空気を送る。具体的には、室外ファン１７は、室外機２の後述する吸込口４４および吸込開口４６から該室外機２の内部へ外気を取り込み、室外熱交換器１３において冷媒と熱交換した外気を後述する吹出口４１から室外機２の外部へ放出する。 The outdoor fan 17 is disposed near the outdoor heat exchanger 13 and sends air toward the outdoor heat exchanger 13. Specifically, the outdoor fan 17 takes in outside air into the outdoor unit 2 through the intake port 44 and intake opening 46, which will be described later, and releases the outside air that has exchanged heat with the refrigerant in the outdoor heat exchanger 13 to the outside of the outdoor unit 2 through the exhaust port 41, which will be described later.
　一方、室内機３は、室内ユニット２３を有する。室内ユニット２３は、例えば、床暖房装置やラジエタが用いられる。室内ユニット２３の一方の冷媒出入口２３Ａは、水冷媒熱交換器１５の水出口１５Ｄと接続されている。また、室内ユニット２３の他方の冷媒出入口２３Ｂは、循環ポンプ２１を介して、水冷媒熱交換器１５の水入口１５Ｃと接続されている。これにより、室内ユニット２３は、水配管１９により水冷媒熱交換器１５と接続されて水回路４を構成し、この水回路４を循環する水と室内ユニット２３において放熱あるいは吸熱を行うことで、室内機３が設置された空調空間の暖房あるいは冷房が行われる。 On the other hand, the indoor unit 3 has an indoor unit 23. For example, a floor heating device or a radiator is used as the indoor unit 23. One refrigerant inlet/outlet 23A of the indoor unit 23 is connected to the water outlet 15D of the water-refrigerant heat exchanger 15. The other refrigerant inlet/outlet 23B of the indoor unit 23 is connected to the water inlet 15C of the water-refrigerant heat exchanger 15 via the circulation pump 21. As a result, the indoor unit 23 is connected to the water-refrigerant heat exchanger 15 by the water piping 19 to form the water circuit 4, and the water circulating through this water circuit 4 dissipates or absorbs heat in the indoor unit 23, thereby heating or cooling the air-conditioned space in which the indoor unit 3 is installed.
＜運転時の動作＞
　次に、ヒートポンプサイクル装置１の運転時の冷媒の流れと水の流れについて説明する。尚、図１における破線矢印は暖房運転時の冷媒の流れを示し、実線矢印は冷房運転時の冷媒の流れを示している。 <Operation during operation>
Next, a description will be given of the flow of refrigerant and the flow of water during operation of the heat pump cycle device 1. Note that the dashed arrows in Fig. 1 indicate the flow of refrigerant during heating operation, and the solid arrows indicate the flow of refrigerant during cooling operation.
　ヒートポンプサイクル装置１が暖房運転を行う場合、四方弁１２は、第１のポート１２Ａと第４のポート１２Ｄとが連通し、第２のポート１２Ｂと第３のポート１２Ｃとが連通するように切替えている。これにより、冷媒回路１０は、水冷媒熱交換器１５が凝縮器として機能し、室外熱交換器１３が蒸発器として機能する暖房サイクルとなる。 When the heat pump cycle device 1 performs heating operation, the four-way valve 12 is switched so that the first port 12A and the fourth port 12D are in communication, and the second port 12B and the third port 12C are in communication. As a result, the refrigerant circuit 10 becomes a heating cycle in which the water-refrigerant heat exchanger 15 functions as a condenser and the outdoor heat exchanger 13 functions as an evaporator.
　冷媒回路１０が上記の状態で圧縮機１１が駆動すると、圧縮機１１から吐出された冷媒は、四方弁１２に流入し、四方弁１２から水冷媒熱交換器１５に流入する。水冷媒熱交換器１５に流入した高温のガス冷媒は、循環ポンプ２１の動作により水冷媒熱交換器１５の水回路４を循環する水との間で熱交換することで凝縮する。一方、水回路４を循環する水は、水冷媒熱交換器１５で冷媒によって加熱されて温水となる。この温水は、水回路４の水配管１９を通じて、室内機３の室内ユニット２３に流入する。そして、室内ユニット２３で温水が放熱することで、室内機３が設置された室内の暖房が行われる。 When the compressor 11 is driven with the refrigerant circuit 10 in the above state, the refrigerant discharged from the compressor 11 flows into the four-way valve 12, and from the four-way valve 12 flows into the water-refrigerant heat exchanger 15. The high-temperature gas refrigerant that flows into the water-refrigerant heat exchanger 15 is condensed by heat exchange with the water circulating in the water circuit 4 of the water-refrigerant heat exchanger 15 due to the operation of the circulation pump 21. Meanwhile, the water circulating in the water circuit 4 is heated by the refrigerant in the water-refrigerant heat exchanger 15 to become hot water. This hot water flows into the indoor unit 23 of the indoor unit 3 through the water piping 19 of the water circuit 4. The hot water then dissipates heat in the indoor unit 23, heating the room in which the indoor unit 3 is installed.
　水冷媒熱交換器１５で水と熱交換して凝縮した液冷媒は、室外膨張弁１４を通過して減圧された後、室外熱交換器１３に流入する。室外熱交換器１３に流入した冷媒は、室外ファン１７の回転によって室外機２内に流入した外気と熱交換を行って蒸発する。室外熱交換器１３で蒸発したガス冷媒は、四方弁１２、アキュムレータ１６の順に通過し、圧縮機１１に吸入されて再び圧縮される。 The liquid refrigerant condensed by heat exchange with water in the water-refrigerant heat exchanger 15 passes through the outdoor expansion valve 14 to be reduced in pressure, and then flows into the outdoor heat exchanger 13. The refrigerant that flows into the outdoor heat exchanger 13 evaporates by exchanging heat with the outside air that flows into the outdoor unit 2 due to the rotation of the outdoor fan 17. The gas refrigerant that has evaporated in the outdoor heat exchanger 13 passes through the four-way valve 12 and the accumulator 16 in that order, and is sucked into the compressor 11 and compressed again.
　また、ヒートポンプサイクル装置１が冷房運転あるいは除霜運転を行う場合、四方弁１２は、第１のポート１２Ａと第２のポート１２Ｂとが連通し、第３のポート１２Ｃと第４のポート１２Ｄとが連通するように切替えられる。これにより、冷媒回路１０は、水冷媒熱交換器１５が蒸発器として機能し、室外熱交換器１３が凝縮器として機能する冷房サイクルとなる。 When the heat pump cycle device 1 performs cooling or defrosting operation, the four-way valve 12 is switched so that the first port 12A communicates with the second port 12B and the third port 12C communicates with the fourth port 12D. As a result, the refrigerant circuit 10 becomes a cooling cycle in which the water-refrigerant heat exchanger 15 functions as an evaporator and the outdoor heat exchanger 13 functions as a condenser.
　冷媒回路１０が上記の状態で圧縮機１１が駆動すると、圧縮機１１から吐出された冷媒は、四方弁１２に流入し、四方弁１２から室外熱交換器１３に流入する。室外熱交換器１３に流入した高温のガス冷媒は、室外ファン１７の回転により室外機２内に取り込まれた室外空気との間で熱交換することで凝縮する。なお、除霜運転を行っている場合は、室外熱交換器１３で発生した霜が、室外熱交換器１３に流入する冷媒の熱によって融解される。 When the compressor 11 is driven with the refrigerant circuit 10 in the above state, the refrigerant discharged from the compressor 11 flows into the four-way valve 12, and from the four-way valve 12 into the outdoor heat exchanger 13. The high-temperature gas refrigerant that flows into the outdoor heat exchanger 13 condenses by exchanging heat with the outdoor air drawn into the outdoor unit 2 by the rotation of the outdoor fan 17. When defrosting operation is being performed, the frost that has formed in the outdoor heat exchanger 13 is melted by the heat of the refrigerant that flows into the outdoor heat exchanger 13.
　室外熱交換器１３で凝縮した液冷媒は、室外膨張弁１４を通過して減圧された後、水冷媒熱交換器１５に流入する。水冷媒熱交換器１５に流入した液冷媒は、循環ポンプ２１の運転により水冷媒熱交換器１５の水回路４を循環する水との間で熱交換することで蒸発する。一方、水回路４を循環する水は、水冷媒熱交換器１５で冷媒によって冷却されて冷水となる。この冷水は、水回路４の水配管１９を通じて、室内機３の室内ユニット２３に流入する。そして、室内ユニット２３で冷水によって室内の空気が吸熱されることで、室内機３が設置された室内の冷房が行われる。なお、除霜運転を行っている場合は、室内温度の低下を抑制するために循環ポンプ２１を停止させて水回路４における水の循環を止める。 The liquid refrigerant condensed in the outdoor heat exchanger 13 passes through the outdoor expansion valve 14 and is reduced in pressure before flowing into the water-refrigerant heat exchanger 15. The liquid refrigerant that has flowed into the water-refrigerant heat exchanger 15 evaporates by exchanging heat with the water circulating in the water circuit 4 of the water-refrigerant heat exchanger 15 due to the operation of the circulation pump 21. Meanwhile, the water circulating in the water circuit 4 is cooled by the refrigerant in the water-refrigerant heat exchanger 15 to become cold water. This cold water flows into the indoor unit 23 of the indoor unit 3 through the water piping 19 of the water circuit 4. The cold water then absorbs heat from the indoor air in the indoor unit 23, thereby cooling the room in which the indoor unit 3 is installed. When defrosting operation is being performed, the circulation pump 21 is stopped to stop the circulation of water in the water circuit 4 in order to prevent the indoor temperature from dropping.
　水冷媒熱交換器１５で蒸発したガス冷媒は、四方弁１２、アキュムレータ１６の順に通過し、圧縮機１１に吸入されて再び圧縮される。 The gas refrigerant that evaporates in the water-refrigerant heat exchanger 15 passes through the four-way valve 12 and the accumulator 16, and is sucked into the compressor 11 and compressed again.
＜室外機の構造＞
　次に、室外機２の外観および内部構造について説明する。図２は、室外機を前面側から見た外観斜視図であり、図３は、室外機を背面側から見た外観斜視図である。図４は、室外機の内部構造を示す斜視図である。なお、以下に述べる前後、上下及び左右といった方向は、室外機２を設置した状態で、後述する吹出口４１から空気が吹き出される方向を前方とし、前面側から室外機２を見た場合の方向を示している。なお、「後方」については「背面」と記載する場合がある。 <Outdoor unit structure>
Next, the appearance and internal structure of the outdoor unit 2 will be described. Fig. 2 is an external perspective view of the outdoor unit as viewed from the front side, and Fig. 3 is an external perspective view of the outdoor unit as viewed from the rear side. Fig. 4 is a perspective view showing the internal structure of the outdoor unit. Note that the directions such as front-rear, up-down, and left-right described below refer to the direction in which air is blown out from an air outlet 41 (described later) when the outdoor unit 2 is installed, as viewed from the front side. Note that "rear" may also be written as "rear".
　図２及び図３に示すように、室外機２は、左右方向（幅方向）の寸法の方が前後方向（奥行方向）の寸法よりも大きい直方体箱形状の筐体３０を備える。この筐体３０は、設置面に対向するように配置される底板（底面パネル）３１と、底板３１よりも高さ方向の上方に配置される天面パネル３２と、底板３１と天面パネル３２とを接続し、筐体３０の内部と外部とを区画する側面パネル部３３とを備えている。 As shown in Figures 2 and 3, the outdoor unit 2 has a rectangular box-shaped housing 30 whose left-right (width) dimension is greater than its front-rear (depth) dimension. This housing 30 has a bottom plate (bottom panel) 31 arranged to face the installation surface, a top panel 32 arranged higher in the height direction than the bottom plate 31, and a side panel portion 33 that connects the bottom plate 31 and the top panel 32 and separates the inside and outside of the housing 30.
　筐体３０の内部は、図４に示すように、底板３１に立設された仕切り板３４によって、熱交換室ＲＡと機械室ＲＢとに区分けされている。熱交換室ＲＡには、該熱交換室ＲＡの背面側に室外熱交換器１３が収容され、前面側に室外ファン１７が収容される。室外熱交換器１３は、上面（天面パネル３２側）から見たときにＬ字形状に屈曲されて形成され、熱交換室ＲＡの背面側から左側面側に沿わせて底板３１に支持されている。 As shown in FIG. 4, the inside of the housing 30 is divided into a heat exchange chamber RA and a machine chamber RB by a partition plate 34 erected on the bottom plate 31. The heat exchange chamber RA houses the outdoor heat exchanger 13 on the rear side of the heat exchange chamber RA and the outdoor fan 17 on the front side. The outdoor heat exchanger 13 is bent in an L-shape when viewed from above (the top panel 32 side), and is supported by the bottom plate 31 along the rear side to the left side of the heat exchange chamber RA.
　室外ファン１７は、底板３１に立設された一対の支持部材３５，３５に取り付けられている。室外ファン１７は、いわゆる軸流ファンであり、図示しないファンモータによる室外ファン１７の回転駆動により、室外機２の外側、すなわち室外熱交換器１３の背面側に形成される吸込口４４（後述する）および左側面側に形成される吸込開口４６（後述する）から外気を熱交換室ＲＡ内に吸い込む。そして、室外熱交換器１３で熱交換後の空気を熱交換室ＲＡの前面側に形成された吹出口４１（後述する）から前方に吹き出す。このように、室外機２は、前面側から熱交換後の空気を吹き出す前面吹き出しタイプの室外機である。 The outdoor fan 17 is attached to a pair of support members 35, 35 erected on the bottom plate 31. The outdoor fan 17 is a so-called axial fan, and as the outdoor fan 17 is driven to rotate by a fan motor (not shown), it draws outside air into the heat exchange chamber RA from the outside of the outdoor unit 2, i.e., from an intake port 44 (described later) formed on the rear side of the outdoor heat exchanger 13 and an intake opening 46 (described later) formed on the left side. Then, the air that has undergone heat exchange in the outdoor heat exchanger 13 is blown forward from an outlet port 41 (described later) formed on the front side of the heat exchange chamber RA. In this way, the outdoor unit 2 is a front-blowout type outdoor unit that blows out air that has undergone heat exchange from the front side.
　機械室ＲＢの下部空間には、冷媒回路１０の一部を構成する圧縮機１１、アキュムレータ１６、四方弁１２（図１）、室外膨張弁１４（図１）などの回路構成部品が配置され、それぞれの回路構成部品は冷媒配管１８により接続される。圧縮機１１及びアキュムレータ１６は、底板３１に固定されている。また、機械室ＲＢの下部空間には、水回路４の一部を構成する水冷媒熱交換器１５、空気抜き弁２２、循環ポンプ２１などの回路構成部品が配置され、それぞれの回路構成部品は水配管１９により接続される。この実施例では、水冷媒熱交換器１５は、機械室ＲＢ（筐体３０）の下部空間における背面側と右側面側との角部の近くに配置され、背面側に後述する水配管１９の接続口４７が設けられている。 In the lower space of the machine room RB, circuit components such as the compressor 11, accumulator 16, four-way valve 12 (Figure 1), and outdoor expansion valve 14 (Figure 1) that constitute part of the refrigerant circuit 10 are arranged, and each circuit component is connected by refrigerant piping 18. The compressor 11 and accumulator 16 are fixed to the bottom plate 31. In addition, in the lower space of the machine room RB, circuit components such as the water-refrigerant heat exchanger 15, air vent valve 22, and circulation pump 21 that constitute part of the water circuit 4 are arranged, and each circuit component is connected by water piping 19. In this embodiment, the water-refrigerant heat exchanger 15 is arranged near the corner between the back side and the right side side in the lower space of the machine room RB (housing 30), and a connection port 47 for the water piping 19 described later is provided on the back side.
　また、機械室ＲＢの上部空間には、室外機２および室内機３の動作を制御するための電装部品を有する電装ユニット２５が配置されている。この電装ユニット２５は、制御基板２７と、電源線や制御線などの配線（以下、電線ともいう）を接続するためのターミナル部２６と、を備え、仕切り板３４に固定されている。 In addition, an electrical unit 25 having electrical components for controlling the operation of the outdoor unit 2 and the indoor unit 3 is arranged in the upper space of the machine room RB. This electrical unit 25 includes a control board 27 and a terminal section 26 for connecting wiring such as a power line and a control line (hereinafter also referred to as electric wires), and is fixed to a partition plate 34.
　次に、筐体３０の側面パネル部３３について説明する。側面パネル部３３は、複数のパネル部材を組み合わせて形成されている。本実施例では、図２及び図３に示すように、側面パネル部３３は、前面パネル３６と、背面パネル３７と、右側面パネル３８と、左側面パネル３９と、サービスパネル４０とを備える。これら前面パネル３６、背面パネル３７、右側面パネル３８及び左側面パネル３９は、筐体３０を上面から見たときに、筐体３０の隣接する２つの面と、これら２つの面に挟まれる角部とを含んだＬ字形状にそれぞれ形成されている。 Next, the side panel portion 33 of the housing 30 will be described. The side panel portion 33 is formed by combining multiple panel members. In this embodiment, as shown in Figures 2 and 3, the side panel portion 33 includes a front panel 36, a rear panel 37, a right side panel 38, a left side panel 39, and a service panel 40. When the housing 30 is viewed from above, the front panel 36, the rear panel 37, the right side panel 38, and the left side panel 39 are each formed in an L-shape that includes two adjacent faces of the housing 30 and a corner portion sandwiched between these two faces.
　具体的には、前面パネル３６は、筐体３０の前面の一部を形成する第１前面部３６Ａと、筐体３０の左側面の一部を形成する第１左側面部３６Ｂとを一体に備える。背面パネル３７は、筐体３０の背面の一部を形成する第１背面部３７Ａと、筐体３０の右側面の一部を形成する第１右側面部３７Ｂとを一体に備える。右側面パネル３８は、筐体３０の右側面の一部を形成する第２右側面部３８Ａと、筐体３０の前面の一部を形成する第２前面部３８Ｂとを一体に備える。左側面パネル３９は、筐体３０の左側面の一部を形成する第２左側面部３９Ａと、筐体３０の背面の一部を形成する第２背面部３９Ｂとを一体に備える。 Specifically, the front panel 36 is integrally formed with a first front portion 36A that forms part of the front surface of the housing 30, and a first left side portion 36B that forms part of the left side surface of the housing 30.

The first front portion 36A and the second front portion 38B are disposed side by side on the left and right to form the front surface of the housing 30. The first front portion 36A is formed with an air outlet 41 through which air that has been heat exchanged inside the heat exchange chamber RA is blown out. The air outlet 41 has, for example, a circular bell mouth 41A, and a part of the outdoor fan 17 is disposed within the bell mouth 41A. A mesh-like fan guard 42 that covers the air outlet 41 is provided in front of the front panel 36. The fan guard 42 is formed in an L-shape when the fan guard 42 is viewed from above, and is disposed along the first front portion 36A to the first left side portion 36B of the front panel 36. The fan guard 42 is fixed to the front panel 36 with a predetermined gap between the top end (upper end) 42A of the fan guard 42 and the top panel 32. In addition, a water shielding plate 43 extending in the left-right (width) direction is provided above the air outlet 41 in the first front portion 36A.
　背面パネル３７の第１背面部３７Ａと左側面パネル３９の第２背面部３９Ｂとは、間隔をあけて左右に並べて配置され、筐体３０の背面を形成する。これら第１背面部３７Ａと第２背面部３９Ｂとの間には、室外熱交換器１３が露出して配置され、この露出した領域が吸込口４４となる。この吸込口４４の後方には、網状のフィンガード４５が設けられている。また、第１背面部３７Ａは、機械室ＲＢの背面側に配置されており、第１背面部３７Ａの下部には、上記した水回路４の水配管１９に接続するための一対の接続口４７，４７と、上記した電装ユニット２５に接続される配線（電線）を筐体３０内に導入するための配線口４８とが設けられている。 The first rear portion 37A of the rear panel 37 and the second rear portion 39B of the left side panel 39 are arranged side by side with a gap between them to form the rear of the housing 30. Between the first rear portion 37A and the second rear portion 39B, the outdoor heat exchanger 13 is arranged exposed, and this exposed area becomes the intake port 44. Behind the intake port 44, a mesh-like finger guard 45 is provided. The first rear portion 37A is also arranged on the rear side of the machine room RB, and the lower portion of the first rear portion 37A is provided with a pair of connection ports 47, 47 for connecting to the water piping 19 of the water circuit 4 described above, and a wiring port 48 for introducing the wiring (electrical wires) connected to the electrical unit 25 described above into the housing 30.
　右側面パネル３８の第２右側面部３８Ａと背面パネル３７の第１右側面部３７Ｂとは、間隔をあけて前後に並べて配置され、筐体３０の前面と背面とを繋ぐ右側面（機械室ＲＢ側の側面）を形成する。これら第２右側面部３８Ａと第１右側面部３７Ｂとの間には、上記したサービスパネル４０が着脱自在に配置されている。このサービスパネル４０を取り外すことにより、機械室ＲＢ内にアクセスすることができ、電装ユニット２５や各種回路構成部品のメンテナンスを容易に実行できる。 The second right side portion 38A of the right side panel 38 and the first right side portion 37B of the rear panel 37 are arranged front to back with a gap between them, forming a right side surface (the side surface on the machine room RB side) that connects the front and rear surfaces of the housing 30. The above-mentioned service panel 40 is detachably arranged between the second right side portion 38A and the first right side portion 37B. By removing this service panel 40, it is possible to access the machine room RB, and maintenance of the electrical unit 25 and various circuit components can be easily performed.
　左側面パネル３９の第２左側面部３９Ａと前面パネル３６の第１左側面部３６Ｂとは、前後に並べて配置され、筐体３０の前面と背面とを繋ぐ左側面を形成する。第２左側面部３９Ａは、室外熱交換器１３の一部と対向し、この第２左側面部３９Ａには、複数の吸込開口４６が形成されている。 The second left side portion 39A of the left side panel 39 and the first left side portion 36B of the front panel 36 are arranged side by side from front to back to form a left side surface that connects the front and rear of the housing 30. The second left side portion 39A faces a part of the outdoor heat exchanger 13, and multiple intake openings 46 are formed in this second left side portion 39A.
　また、室外機２は重量物であるため、筐体３０の側面パネル部３３には、室外機２を運搬するための複数の取手部５１，５２，５３が設けられている。これらの取手部５１～５３は、それぞれ筐体３０の角部近傍に配置されている。すなわち、複数の取手部５１～５３は、サービスパネル４０を避けた背面パネル３７、右側面パネル３８及び左側面パネル３９にそれぞれ設けられている。また、サービスパネル４０を外して、機械室ＲＢ内の機器の作業をしている場合に、例えば、結線時に配線がターミナル部２６に届かないといった事態が生じたとしても、取手部５１～５３を用いて室外機２を容易に移動することができる。 Because the outdoor unit 2 is heavy, the side panel portion 33 of the housing 30 is provided with multiple handles 51, 52, 53 for transporting the outdoor unit 2. These handles 51-53 are each located near the corners of the housing 30. That is, the multiple handles 51-53 are provided on the rear panel 37, right side panel 38, and left side panel 39, respectively, avoiding the service panel 40. Furthermore, when the service panel 40 is removed and work is being done on equipment in the machine room RB, even if, for example, the wiring does not reach the terminal portion 26 when connecting the wiring, the outdoor unit 2 can be easily moved using the handles 51-53.

　次に、ファンガード４２について説明する。図５は、ファンガードを前面側から見た斜視図であり、図６は、ファンガードを取り外した室外機を前面側から見た外観斜視図である。図７は、図２のＡ－Ａ線で示す断面をＸ方向から見た室外機の支持部の部分断面図である。図８は、図２のＢ－Ｂ線で示す断面をＸ方向から見た室外機の突条部の部分断面図である。図９は、図２のＣ－Ｃ線で示す断面をＺ方向から見た室外機の左側凹部の部分断面図である。なお、図７～図９において、筐体３０に取り付けられる前の状態のファンガード４２を二点鎖線で示している。ファンガード４２は、前面パネル３６の前方に配置されて吹出口４１を覆い、例えば吹出口４１から手指や異物を挿入して室外ファン１７に触れることで発生する事故を未然に防止する。ファンガード４２は、図５に示すように、前面部４２０と左側面部（側面部）４２１とを一体に備え、該ファンガード４２を上方から見たときにＬ字形状に形成されている。 <Fan guard>
Next, the fan guard 42 will be described. FIG. 5 is a perspective view of the fan guard as viewed from the front side, and FIG. 6 is an external perspective view of the outdoor unit with the fan guard removed as viewed from the front side. FIG. 7 is a partial cross-sectional view of the support part of the outdoor unit as viewed from the X direction in the cross section shown by line A-A in FIG. 2. FIG. 8 is a partial cross-sectional view of the protruding part of the outdoor unit as viewed from the X direction in the cross section shown by line B-B in FIG. 2. FIG. 9 is a partial cross-sectional view of the left recess of the outdoor unit as viewed from the Z direction in the cross section shown by line C-C in FIG. 2. In addition, in FIGS. 7 to 9, the fan guard 42 in a state before being attached to the housing 30 is shown by a two-dot chain line. The fan guard 42 is disposed in front of the front panel 36 to cover the air outlet 41, and prevents accidents that may occur, for example, when a finger or a foreign object is inserted through the air outlet 41 and touches the outdoor fan 17. As shown in FIG. 5, the fan guard 42 is integrally provided with a front portion 420 and a left side portion (side portion) 421, and is formed in an L-shape when viewed from above.
　また、ファンガード４２は、図２に示すように、底板３１から天面パネル３２までの領域において前面パネル３６の前方に配置され、該前面パネル３６に固定される。図２の例では、ファンガード４２の前面部４２０は前面パネル３６の第１前面部３６Ａに固定され、左側面部４２１は前面パネル３６の第１左側面部３６Ｂに固定されている。 Furthermore, as shown in FIG. 2, the fan guard 42 is disposed in front of the front panel 36 in the region from the bottom plate 31 to the top panel 32, and is fixed to the front panel 36. In the example of FIG. 2, the front portion 420 of the fan guard 42 is fixed to the first front portion 36A of the front panel 36, and the left side portion 421 is fixed to the first left side portion 36B of the front panel 36.
　ファンガード４２は、図５に示すように、横方向に延在する複数本の横線材６０と、縦方向に延在する複数本の縦線材６１とを網目状に組み合わせて形成される。これら横線材６０及び縦線材６１は、本実施例では鉄製であり、各線材の接点をそれぞれスポット溶接することでファンガード４２が形成される。複数本の横線材６０は、それぞれＬ字形状に曲げられて形成されている。複数本の横線材６０は、それぞれ上下にほぼ等間隔に配置され、横線材６０同士の間隔は少なくとも手指の挿入を防止できる間隔となっている。 As shown in FIG. 5, the fan guard 42 is formed by combining multiple horizontal wires 60 extending laterally and multiple vertical wires 61 extending vertically in a mesh pattern. In this embodiment, the horizontal wires 60 and vertical wires 61 are made of iron, and the fan guard 42 is formed by spot welding the contact points of each wire. The multiple horizontal wires 60 are each bent into an L shape. The multiple horizontal wires 60 are arranged vertically and at approximately equal intervals, and the intervals between the horizontal wires 60 are at least sufficient to prevent the insertion of fingers.
　複数本の横線材６０の一端（図５の左端）には、それぞれ先端を前面パネル３６の第１左側面部３６Ｂ（図２）側に屈曲した左屈曲部（第１横屈曲部）６０１が設けられている。また、複数本の横線材６０の他端（図５の右端）には、それぞれ先端を前面パネル３６の第１前面部３６Ａ（図２）側に屈曲した右屈曲部（第２横屈曲部）６０２が設けられている。さらに、本実施例では、複数本の横線材６０のうちの１本（一部）の横線材６０Ａの一端には、左屈曲部６０１に連なる左突起部（第１横突起部）６０３が設けられている。この左突起部６０３は、左屈曲部６０１の先端を階段状に屈曲させて形成され、横線材６０Ａの延在方向（図５の後方）に突出している。また、上記した横線材６０Ａの他端には、右屈曲部６０２に連なる右突起部（第２横突起部）６０４が設けられている。この右突起部６０４は、右屈曲部６０２の先端を下方に屈曲させて形成され、そのまま下方に突出している。 At one end (left end in FIG. 5) of each of the horizontal wires 60, a left bent portion (first horizontal bent portion) 601 is provided with a tip bent toward the first left side portion 36B (FIG. 2) of the front panel 36. At the other end (right end in FIG. 5) of each of the horizontal wires 60, a right bent portion (second horizontal bent portion) 602 is provided with a tip bent toward the first front portion 36A (FIG. 2) of the front panel 36. Furthermore, in this embodiment, at one end of one (part of) horizontal wire 60A of the horizontal wires 60, a left protrusion portion (first horizontal protrusion portion) 603 connected to the left bent portion 601 is provided. This left protrusion portion 603 is formed by bending the tip of the left bent portion 601 in a stepped shape, and protrudes in the extension direction of the horizontal wire 60A (rear in FIG. 5). In addition, the other end of the horizontal wire 60A is provided with a right protrusion (second horizontal protrusion) 604 that is connected to the right bent portion 602. This right protrusion 604 is formed by bending the tip of the right bent portion 602 downward, and protrudes downward as it is.
　これら左突起部６０３及び右突起部６０４は、前面パネル３６に対するファンガード４２の位置決め及び仮固定をするための突起である。左突起部６０３及び右突起部６０４は、前面パネル３６の高さ寸法の半分よりも上方の領域に形成され、図５の例では、上から約１／３の高さ位置に形成されている。なお、図５の例では、左突起部６０３と右突起部６０４とは、それぞれ同じ横線材６０Ａの両端に形成されているが、異なる横線材６０Ａに形成される構成としてもよい。この場合、左突起部６０３及び右突起部６０４は、いずれも前面パネル３６の高さ寸法の半分よりも上方の領域に形成され、例えば上から１／３程度の高さ位置に形成されることが好ましい。これにより、作業者は前面パネル３６に対するファンガード４２の位置決め及び仮固定を容易に行うことができる。 The left protrusion 603 and the right protrusion 604 are protrusions for positioning and temporarily fixing the fan guard 42 to the front panel 36. The left protrusion 603 and the right protrusion 604 are formed in an area above half the height of the front panel 36, and in the example of FIG. 5, they are formed at a height position of about 1/3 from the top. In the example of FIG. 5, the left protrusion 603 and the right protrusion 604 are formed at both ends of the same horizontal wire 60A, but they may be formed on different horizontal wires 60A. In this case, it is preferable that the left protrusion 603 and the right protrusion 604 are both formed in an area above half the height of the front panel 36, and are formed at a height position of about 1/3 from the top. This allows the worker to easily position and temporarily fix the fan guard 42 to the front panel 36.
　一方、複数の縦線材６１は、横線材６０を該縦線材６１にスポット溶接により固定してファンガード４２の強度を確保するために設けられている。本実施例では、縦線材６１は、横線材６０よりも径の太い線材が用いられ、複数の縦線材６１同士の間隔は、横線材６０同士の間隔よりも広く形成されている。図５に示すように、複数の縦線材６１のうち、ファンガード４２の前面部４２０における左右の両端にはそれぞれ固定用縦線材（一部の縦線材）６１Ａが配置される。また、ファンガード４２の左側面部４２１における後端（背面側の端）には固定用縦線材６１Ａが配置される。これら固定用縦線材６１Ａは、前面パネル３６にファンガード４２を取り付け・固定するためのものであり、上下の両端にそれぞれ、輪形状に形成される上ねじ止め部６１１及び下ねじ止め部６１２を備える。上ねじ止め部６１１は、ファンガード４２の上方に突出する。下ねじ止め部６１２は、ファンガード４２の下方に突出する。本実施例では、下ねじ止め部６１２は、ファンガード４２の下端に設けられて下方に突出しており、特に前面部４２０の下端に設けられた下ねじ止め部６１２は、後述する下突起部（第２下突起部）として機能する。これら上ねじ止め部６１１及び下ねじ止め部６１２を前面パネル３６にそれぞれねじ止めすることでファンガード４２が前面パネル３６に固定される。 On the other hand, the vertical wires 61 are provided to secure the strength of the fan guard 42 by fixing the horizontal wires 60 to the vertical wires 61 by spot welding. In this embodiment, the vertical wires 61 are made of wires with a larger diameter than the horizontal wires 60, and the spacing between the vertical wires 61 is wider than the spacing between the horizontal wires 60. As shown in FIG. 5, among the vertical wires 61, fixing vertical wires (part of the vertical wires) 61A are arranged at both the left and right ends of the front surface 420 of the fan guard 42. In addition, fixing vertical wires 61A are arranged at the rear end (end on the rear side) of the left side surface 421 of the fan guard 42. These fixing vertical wires 61A are for attaching and fixing the fan guard 42 to the front panel 36, and are provided with an upper screw fastening portion 611 and a lower screw fastening portion 612 formed in a ring shape at both the upper and lower ends. The upper screw fastening portion 611 protrudes above the fan guard 42. The lower screw fastening portion 612 protrudes below the fan guard 42. In this embodiment, the lower screw fastening portion 612 is provided at the lower end of the fan guard 42 and protrudes downward, and in particular, the lower screw fastening portion 612 provided at the lower end of the front surface portion 420 functions as a lower protrusion (second lower protrusion) described below. The fan guard 42 is fixed to the front panel 36 by screwing the upper screw fastening portion 611 and the lower screw fastening portion 612 to the front panel 36, respectively.
　また、ファンガード４２の前面部４２０における２本の固定用縦線材６１Ａの間に配置される複数本の縦線材６１は、それぞれ上端が前面パネル３６の第１前面部３６Ａ（図２）側に屈曲して上記したファンガード４２の上端部４２Ａを形成する。 Furthermore, the upper ends of the multiple vertical wires 61 arranged between the two fixing vertical wires 61A on the front surface 420 of the fan guard 42 are bent toward the first front surface 36A (Figure 2) of the front panel 36 to form the upper end 42A of the fan guard 42 described above.
　また、ファンガード４２の前面部４２０における２本の固定用縦線材６１Ａの間に配置される複数本の縦線材６１の下端には、それぞれ前面パネル３６の第１前面部３６Ａ（図２）側に屈曲する下屈曲部６１３が設けられている。本実施例では、室外機を水平面上に設置した場合に、これら下屈曲部６１３は、水平よりも斜め上方に折り返すように屈曲され、該下屈曲部６１３の先端には、ファンガード４２の強度を保つため横方向の補助線材６２が設けられている。 Furthermore, the lower ends of the vertical wires 61 arranged between the two fixing vertical wires 61A on the front surface 420 of the fan guard 42 are provided with downward bends 613 that bend toward the first front surface 36A (FIG. 2) of the front panel 36. In this embodiment, when the outdoor unit is installed on a horizontal surface, these downward bends 613 are bent so as to fold back diagonally upward from the horizontal, and horizontal auxiliary wires 62 are provided at the tips of the downward bends 613 to maintain the strength of the fan guard 42.
　また、上記した複数本の縦線材６１のうちの一部（図５では３本）の縦線材６１Ｂの下端には、下屈曲部６１３に連なる位置決め突起部６１４が設けられている。この位置決め突起部６１４は、下屈曲部６１３の先端を階段状に下方に屈曲させて形成され、下方にそのままに突出している。この位置決め突起部６１４は、前面パネル３６に対するファンガード４２の位置決めをするための突起であり、後述する下突起部（第１下突起部）として機能する。 Furthermore, a positioning protrusion 614 that is connected to the lower bend 613 is provided at the lower end of some (three in FIG. 5) of the vertical wires 61B among the above-mentioned vertical wires 61. This positioning protrusion 614 is formed by bending the tip of the lower bend 613 downward in a stepped shape, and protrudes downward as it is. This positioning protrusion 614 is a protrusion for positioning the fan guard 42 relative to the front panel 36, and functions as a lower protrusion (first lower protrusion) described later.
　また、下屈曲部６１３は、前面パネル３６の第１前面部３６Ａ側に向けて、水平よりも斜め上方に折り返すように屈曲される。このため、下屈曲部６１３は、該下屈曲部６１３と縦線材６１との角部、すなわち下屈曲部６１３の前方側（一部）に、最も下方に位置する下部６１３Ａを有する。この下部６１３Ａは、ファンガード４２を前面パネル３６に配置された際に、前面パネル３６の第１前面部３６Ａに設けられた後述する支持部７０上に載置され、ファンガード４２は支持部７０に支持される。このため、本実施例では、下屈曲部６１３の下部６１３Ａは、ファンガード４２の下端に設けられ支持部７０に載置される載置部として機能する。また、上記した位置決め突起部６１４は、下屈曲部６１３の下部６１３Ａよりもファンガード４２の後方側に形成され、下ねじ止め部６１２は、該下屈曲部６１３の下部６１３Ａよりもファンガード４２の前方側に形成される。この構成によれば、ファンガード４２の前面部４２０が外郭パネルと同一面か、設計上許容できる範囲で少し出っ張る位置に設けることができ、ファンガード４２を適切に配置できる。 The lower bent portion 613 is bent so as to fold back diagonally upward from the horizontal toward the first front portion 36A of the front panel 36. For this reason, the lower bent portion 613 has a lower part 613A located at the corner between the lower bent portion 613 and the vertical wire 61, i.e., at the front side (part) of the lower bent portion 613. When the fan guard 42 is placed on the front panel 36, this lower part 613A is placed on a support part 70 (described later) provided on the first front portion 36A of the front panel 36, and the fan guard 42 is supported by the support part 70. For this reason, in this embodiment, the lower part 613A of the lower bent portion 613 functions as a placement part provided at the lower end of the fan guard 42 and placed on the support part 70. In addition, the positioning protrusion 614 is formed on the rear side of the fan guard 42 relative to the lower portion 613A of the downward bend 613, and the lower screw fastening portion 612 is formed on the front side of the fan guard 42 relative to the lower portion 613A of the downward bend 613. With this configuration, the front portion 420 of the fan guard 42 can be positioned flush with the outer panel or slightly protruding within the range allowed by the design, allowing the fan guard 42 to be positioned appropriately.
　筐体３０の前面パネル３６は、図６に示すように、第１前面部３６Ａの下部にファンガード４２が支持される支持部７０を備える。具体的には、第１前面部３６Ａは、該第１前面部３６Ａの前端部３６Ａ１よりも後方（筐体の背面側）に凹んだ凹部７１を有し、この凹部７１における前端部３６Ａ１と連なる下部壁面に支持部７０が形成される。 As shown in FIG. 6, the front panel 36 of the housing 30 has a support portion 70 at the bottom of the first front portion 36A that supports the fan guard 42. Specifically, the first front portion 36A has a recess 71 that is recessed rearward (toward the rear side of the housing) from the front end portion 36A1 of the first front portion 36A, and the support portion 70 is formed on the lower wall surface of this recess 71 that is connected to the front end portion 36A1.
　この支持部７０は、ファンガード４２における下屈曲部６１３の下部６１３Ａと当接して、該ファンガード４２を支持する平坦面を含む。なお、支持部７０は、図７に示すように、凹部７１に連なる箇所は断面円弧形状となっている。また、図６に示すように、支持部７０には、左右方向に間隔をあけて複数（図６では３つ）の孔部（下受け部）７２が設けられている。これら孔部７２は、一部の縦線材６１Ｂの下端に設けられた位置決め突起部６１４が挿し込まれるものであり、該位置決め突起部６１４に対応する位置に設けられている。また、本実施例では、３つの孔部７２のうち、中央の孔部７２が丸孔として形成され、左右２つの孔部７２は、左右方向に長軸を有する長孔として形成される。このため、中央の位置決め突起部６１４を中央の孔部７２に挿し込むことで、ファンガード４２の左右方向のセンター位置を位置決めすることができる。また、左右の孔部７２を長孔とすることで、センターを位置決めしつつ、ファンガード４２（左右の位置決め突起部６１４）の寸法誤差を吸収できる。 The support portion 70 includes a flat surface that abuts against the lower portion 613A of the lower bent portion 613 in the fan guard 42 to support the fan guard 42. As shown in FIG. 7, the support portion 70 has an arc-shaped cross section at the portion that connects to the recess 71. As shown in FIG. 6, the support portion 70 has a plurality of holes (lower support portions) 72 (three in FIG. 6) spaced apart in the left-right direction. These holes 72 are inserted with positioning protrusions 614 provided at the lower ends of some of the vertical wires 61B, and are provided at positions corresponding to the positioning protrusions 614. In this embodiment, of the three holes 72, the central hole 72 is formed as a round hole, and the two left and right holes 72 are formed as long holes having a long axis in the left-right direction. Therefore, by inserting the central positioning protrusion 614 into the central hole 72, the center position of the fan guard 42 in the left-right direction can be determined. In addition, by making the left and right holes 72 long holes, the center can be positioned while absorbing dimensional errors in the fan guard 42 (left and right positioning protrusions 614).
　また、図７に示すように、第１前面部３６Ａに形成された凹部７１の奥行寸法は、ファンガード４２を該凹部７１の内部に収めることができる寸法となっている。具体的には、ファンガード４２が支持部７０上に配置されるとき、ファンガード４２の下屈曲部６１３の下部６１３Ａが支持部７０に当接する。また、該下部６１３Ａよりも後方側に設けられる位置決め突起部６１４が支持部７０に形成された孔部７２にそれぞれ挿し込まれる。このように、ファンガード４２が該凹部７１の内部に収まるため、ファンガード４２の前面部４２０は前端部３６Ａ１や第２前面部３８Ｂと略面一となるように配置される。さらに、下部６１３Ａよりも前方側に設けられる下ねじ止め部６１２は、第１前面部３６Ａの前端部３６Ａ１に沿って延在し、ボルト（ねじ）１００によって前端部３６Ａ１に固定される。これにより、ファンガード４２は、位置決め突起部６１４及び下ねじ止め部６１２によって、前面パネル３６に対して前後及び左右方向の位置決めがされる。本実施例では、ファンガード４２は、第１前面部３６Ａの前端部３６Ａ１と面一、もしくは設計上の許容する範囲内で少し出張った位置に位置決めした状態で固定される。 7, the depth dimension of the recess 71 formed in the first front portion 36A is a dimension that allows the fan guard 42 to be accommodated inside the recess 71. Specifically, when the fan guard 42 is placed on the support portion 70, the lower portion 613A of the lower bent portion 613 of the fan guard 42 abuts against the support portion 70. In addition, the positioning protrusions 614 provided on the rear side of the lower portion 613A are inserted into the holes 72 formed in the support portion 70. In this way, since the fan guard 42 fits inside the recess 71, the front portion 420 of the fan guard 42 is arranged so as to be approximately flush with the front end portion 36A1 and the second front portion 38B. Furthermore, the lower screw fastening portion 612 provided on the front side of the lower portion 613A extends along the front end portion 36A1 of the first front portion 36A and is fixed to the front end portion 36A1 by the bolt (screw) 100. As a result, the fan guard 42 is positioned in the front-rear and left-right directions relative to the front panel 36 by the positioning protrusions 614 and the lower screw fastening portion 612. In this embodiment, the fan guard 42 is fixed in a state where it is flush with the front end portion 36A1 of the first front portion 36A, or is positioned in a position that protrudes slightly from the front end portion 36A1 within the range allowed by the design.
　前面パネル３６は、図６に示すように、第１前面部３６Ａにおける右側面パネル３８の第２前面部３８Ｂ側に上下方向に延在する突条部７４を備える。この突条部７４は凹部７１と隣接して設けられ、該凹部７１よりも前方に突出するものの、右側面パネル３８の第２前面部３８Ｂよりも後方に凹んで形成されている。この突条部７４の前面側には、ファンガード４２の右突起部６０４に対応する位置に該右突起部６０４が挿し込まれる右孔部（第２横受け部）７５が形成されている。この右孔部７５は、図８に示すように、下方に屈曲された右突起部６０４の上下方向の長さ寸法よりも長い上下方向の長さ寸法を有する長孔として形成される。右突起部６０４が右孔部７５に挿し込まれた状態で、上記した位置決め突起部６１４が各孔部７２に挿し込まれると、ファンガード４２は、下屈曲部６１３の下部６１３Ａと支持部７０とが当接するまで第１前面部３６Ａに対して下降して該支持部７０に支持される。このため、右孔部７５の下端７５Ａと右突起部６０４の下端６０４Ａとが高さ方向の所定寸法だけ重なることにより、ファンガード４２が前方、すなわち作業者側に傾倒することが防止される。これにより、ファンガード４２を前面パネル３６に仮固定することができるため、作業者は積極的にファンガード４２を手で保持しなくても該ファンガード４２の固定を行うことができる。 As shown in Figure 6, the front panel 36 has a protrusion 74 that extends in the vertical direction on the side of the second front portion 38B of the right side panel 38 in the first front portion 36A. This protrusion 74 is provided adjacent to the recess 71 and protrudes forward from the recess 71, but is recessed rearward from the second front portion 38B of the right side panel 38. A right hole (second cross support portion) 75 into which the right protrusion 604 is inserted is formed on the front side of this protrusion 74 at a position corresponding to the right protrusion 604 of the fan guard 42. This right hole 75 is formed as a long hole having a vertical length dimension longer than the vertical length dimension of the downwardly bent right protrusion 604, as shown in Figure 8. When the positioning protrusions 614 are inserted into the holes 72 with the right protrusion 604 inserted into the right hole 75, the fan guard 42 descends relative to the first front surface 36A until the lower portion 613A of the downward bend 613 abuts against the support portion 70 and is supported by the support portion 70. Therefore, the lower end 75A of the right hole 75 and the lower end 604A of the right protrusion 604 overlap by a predetermined dimension in the height direction, preventing the fan guard 42 from tilting forward, i.e., toward the worker. This allows the fan guard 42 to be provisionally fixed to the front panel 36, so the worker can fix the fan guard 42 without actively holding it with his or her hands.
　また、前面パネル３６は、図６、図９に示すように、第１左側面部３６Ｂに設けられた左側凹部８０を有する。この左側凹部８０は、第１左側面部３６Ｂの左側端部３６Ｂ１よりも筐体の右側面側に凹み、上下方向に延在している。また、前面パネル３６は、第１左側面部３６Ｂにおける左側面パネル３９の第２左側面部３９Ａ側に上下方向に延在し、左側端部３６Ｂ１と左側凹部８０とを繋ぐ壁部８１を備える。この壁部８１には、上記したファンガード４２の左突起部６０３に対応する位置に該左突起部６０３が挿し込まれる左孔部（第１横受け部）８２が形成されている。 The front panel 36 also has a left recess 80 provided in the first left side portion 36B, as shown in Figs. 6 and 9. This left recess 80 is recessed toward the right side of the housing from the left end portion 36B1 of the first left side portion 36B, and extends in the vertical direction. The front panel 36 also has a wall portion 81 that extends in the vertical direction toward the second left side portion 39A of the left side panel 39 at the first left side portion 36B, and connects the left end portion 36B1 and the left recess 80. A left hole portion (first cross support portion) 82 into which the left protrusion portion 603 is inserted is formed in the wall portion 81 at a position corresponding to the left protrusion portion 603 of the fan guard 42 described above.
　ファンガード４２を前面パネル３６に取り付ける場合、図９に示すように、ファンガード４２を前面パネル３６に対して、矢印γ方向に移動させることにより、ファンガード４２の左突起部６０３は、上記した壁部８１に形成された左孔部８２に挿入される。この左孔部８２は、後方に突出した左突起部６０３を受け入れることにより、ファンガード４２の左右方向の移動が規制されて、該ファンガード４２の左右方向の位置決めをすることができる。このため、ファンガード４２の外側の開き（左右方向の移動）を規制でき、ファンガード４２に形成された上ねじ止め部６１１及び下ねじ止め部６１２と、筐体３０に形成されたねじ穴との左右方向のズレを防止し、作業者は上ねじ止め部６１１及び下ねじ止め部６１２とねじ穴とがそれぞれ合致した状態でねじ止めすることができる。さらに、図７及び８に示すように、ファンガード４２を前面パネル３６に対して、矢印α方向（β方向）に移動させることにより、ファンガード４２の右突起部６０４が上記突条部７４の右孔部７５に挿し込まれるとともに、ファンガード４２の位置決め突起部６１４が上記支持部７０に形成された孔部７２にそれぞれ挿し込まれる。このため、右突起部６０４が右孔部７５に挿し込まれた状態で、位置決め突起部６１４が各孔部７２に挿し込まれると、ファンガード４２は、下屈曲部６１３の下部６１３Ａと支持部７０とが当接するまで第１前面部３６Ａに対して下降して該支持部７０に支持される。この構成により、ファンガード４２の下方への落ち込みを規制でき、上ねじ止め部６１１及び下ねじ止め部６１２と、筐体３０に形成されたねじ穴との上下方向のズレを防止し、作業者は上ねじ止め部６１１及び下ねじ止め部６１２とねじ穴とがそれぞれ合致した状態でねじ止めすることができ、作業効率が向上する。さらには、右孔部７５の下端７５Ａと右突起部６０４の下端６０４Ａとが高さ方向の所定寸法だけ重なることにより、ファンガード４２が前方、すなわち作業者側に傾倒することが防止される。このため、作業者は、積極的に片手でファンガード４２を保持しつつ、ねじ止めするなどの作業が発生しない。このような構成によれば、本実施例のような大型のファンガード４２を前面パネル３６に取り付ける際に、該前面パネル３６に対するファンガード４２の位置決め及び仮固定が行える。このため、ファンガード４２のねじ止め作業が容易となる。 When attaching the fan guard 42 to the front panel 36, as shown in FIG. 9, the fan guard 42 is moved in the direction of the arrow γ relative to the front panel 36, so that the left protrusion 603 of the fan guard 42 is inserted into the left hole 82 formed in the wall portion 81 described above. This left hole 82 receives the left protrusion 603 protruding rearward, thereby restricting the left-right movement of the fan guard 42 and allowing the left-right positioning of the fan guard 42. This restricts the outward opening (left-right movement) of the fan guard 42, prevents left-right misalignment between the upper screw fastening portion 611 and the lower screw fastening portion 612 formed on the fan guard 42 and the screw holes formed in the housing 30, and allows the operator to screw in the upper screw fastening portion 611 and the lower screw fastening portion 612 in a state where they are aligned with the screw holes. 7 and 8, by moving the fan guard 42 in the direction of arrow α (direction β) relative to the front panel 36, the right protrusion 604 of the fan guard 42 is inserted into the right hole 75 of the protruding strip 74, and the positioning protrusions 614 of the fan guard 42 are inserted into the holes 72 formed in the support part 70. Therefore, when the positioning protrusions 614 are inserted into the holes 72 with the right protrusion 604 inserted into the right hole 75, the fan guard 42 descends relative to the first front surface part 36A until the lower part 613A of the downward bent part 613 comes into contact with the support part 70, and is supported by the support part 70. This configuration prevents the fan guard 42 from falling downward, prevents the upper screw fastening portion 611 and the lower screw fastening portion 612 from misaligning with the screw holes formed in the housing 30, and allows the worker to screw the upper screw fastening portion 611 and the lower screw fastening portion 612 in a state where the screw holes are aligned, improving work efficiency. Furthermore, the lower end 75A of the right hole portion 75 and the lower end 604A of the right protrusion portion 604 overlap by a predetermined dimension in the height direction, preventing the fan guard 42 from tilting forward, i.e., toward the worker. Therefore, the worker does not have to actively hold the fan guard 42 with one hand and perform tasks such as screwing. With this configuration, when attaching a large fan guard 42 such as that in this embodiment to the front panel 36, the fan guard 42 can be positioned and temporarily fixed to the front panel 36. This makes it easier to screw the fan guard 42.
　以上、本実施例に係るヒートポンプサイクル装置１の室外機２は、室外熱交換器１３と、室外熱交換器１３に空気を送風する室外ファン１７とを格納する筐体３０を有し、筐体３０は、室外ファン１７の回転により室外熱交換器１３で冷媒と熱交換した空気を筐体３０の外部に吹き出すための吹出口４１を設けた前面パネル３６と、前面パネル３６に取り付けられて吹出口４１を覆うファンガード４２とを有し、前面パネル３６の下部には、ファンガード４２が支持される支持部７０が設けられる。この構成によれば、例えば大型化されたファンガード４２を前面パネル３６の下部に設けられた支持部７０に支持させた状態で、該ファンガード４２の取り付け作業を行うことができるため、この取り付け作業の作業性を改善することができる。 As described above, the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment has a housing 30 that houses the outdoor heat exchanger 13 and the outdoor fan 17 that blows air to the outdoor heat exchanger 13. The housing 30 has a front panel 36 provided with an outlet 41 for blowing air that has exchanged heat with the refrigerant in the outdoor heat exchanger 13 by the rotation of the outdoor fan 17 to the outside of the housing 30, and a fan guard 42 attached to the front panel 36 and covering the outlet 41. A support portion 70 that supports the fan guard 42 is provided at the bottom of the front panel 36. With this configuration, for example, the fan guard 42 can be attached while being supported by the support portion 70 provided at the bottom of the front panel 36, improving the workability of the attachment work.
　また、本実施例に係るヒートポンプサイクル装置１の室外機２において、ファンガード４２の下端には、支持部７０に載置される下屈曲部６１３の下部６１３Ａと、下方に突出する位置決め突起部６１４及び下ねじ止め部６１２とが設けられているため、下屈曲部６１３の下部６１３Ａを支持部７０上に載せた状態で、ファンガード４２の位置決め及び取り付けを容易に行うことができる。 In addition, in the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment, the lower end of the fan guard 42 is provided with the lower portion 613A of the lower bent portion 613 that is placed on the support portion 70, the positioning protrusion portion 614 that protrudes downward, and the lower screw fastening portion 612, so that the fan guard 42 can be easily positioned and attached with the lower portion 613A of the lower bent portion 613 placed on the support portion 70.
　また、本実施例に係るヒートポンプサイクル装置１の室外機２において、ファンガード４２は、下屈曲部６１３の下部６１３Ａよりも後方側に配置される位置決め突起部６１４と、該下部６１３Ａよりも前方側に配置される下ねじ止め部６１２とを備えるため、これら位置決め突起部６１４及び下ねじ止め部６１２によって、ファンガード４２の前面パネル３６に対する前後及び左右方向の位置決めを行うことができる。このため、ファンガード４２の取り付けを容易に行うことができる。 In addition, in the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment, the fan guard 42 has a positioning protrusion 614 that is positioned rearward of the lower portion 613A of the lower bent portion 613, and a lower screw fastening portion 612 that is positioned forward of the lower portion 613A, so that the positioning protrusion 614 and the lower screw fastening portion 612 can be used to position the fan guard 42 in the front-rear and left-right directions relative to the front panel 36. This makes it easy to attach the fan guard 42.
　また、本実施例に係るヒートポンプサイクル装置１の室外機２において、支持部７０は、位置決め突起部６１４が挿し込まれる孔部７２を有するため、これら孔部７２に位置決め突起部６１４を挿し込むことにより、ファンガード４２の前面パネル３６に対する前後及び左右方向の位置決めを容易に行うことができる。 In addition, in the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment, the support portion 70 has holes 72 into which the positioning protrusions 614 are inserted, so that the positioning of the fan guard 42 relative to the front panel 36 can be easily performed in the front-rear and left-right directions by inserting the positioning protrusions 614 into these holes 72.
　また、本実施例に係るヒートポンプサイクル装置１の室外機２において、ファンガード４２は、縦に延びる複数の縦線材６１と横に延びる複数の横線材６０とを網目状に組み合わせて形成され、位置決め突起部６１４及び下ねじ止め部６１２は、少なくとも一部の縦線材６１Ａ，６１Ｂの下端を下方に突出させて形成される。このため、ファンガード４２の位置決め及び取り付けを簡易な構成で実現することができる。 In the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment, the fan guard 42 is formed by combining multiple vertical wires 61 extending vertically and multiple horizontal wires 60 extending horizontally in a mesh pattern, and the positioning protrusions 614 and the lower screw fastening portion 612 are formed by protruding the lower ends of at least some of the vertical wires 61A, 61B downward. This allows the positioning and installation of the fan guard 42 to be achieved with a simple configuration.
　また、本実施例に係るヒートポンプサイクル装置１の室外機２において、ファンガード４２は、筐体３０の前面パネル３６の吹出口４１を覆う前面部４２０と、筐体３０の左側面側の一部を覆う左側面部４２１とを備えて一体に形成され、位置決め突起部６１４は、前面部４２０の下端に形成される。このため、吹出口４１に対する前面部４２０の位置決めを容易に行うことができ、ファンガード４２を前面パネル３６に容易に取り付けることができる。 In the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment, the fan guard 42 is integrally formed with a front portion 420 that covers the air outlet 41 of the front panel 36 of the housing 30 and a left side portion 421 that covers part of the left side of the housing 30, and the positioning protrusion 614 is formed at the lower end of the front portion 420. This makes it easy to position the front portion 420 relative to the air outlet 41, and the fan guard 42 can be easily attached to the front panel 36.
　また、本実施例に係るヒートポンプサイクル装置１の室外機２において、一部の横線材６０Ａの両端には、左突起部６０３と右突起部６０４とが形成されており、前面パネル３６は、左突起部６０３及び右突起部６０４に対応する位置に、左突起部６０３が挿し込まれる左孔部８２と、右突起部６０４が挿し込まれる右孔部７５とを有する。このため、ファンガード４２を前面パネル３６に取り付ける際に、該前面パネル３６に対するファンガード４２の位置決め及び仮固定を実行できる。このため、ファンガード４２のねじ止め作業が容易となり、ファンガード４２を前面パネル３６に容易に取り付けることができる。 In addition, in the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment, a left protrusion 603 and a right protrusion 604 are formed on both ends of some of the horizontal wires 60A, and the front panel 36 has a left hole 82 into which the left protrusion 603 is inserted and a right hole 75 into which the right protrusion 604 is inserted, at positions corresponding to the left protrusion 603 and the right protrusion 604. Therefore, when attaching the fan guard 42 to the front panel 36, the fan guard 42 can be positioned and temporarily fixed relative to the front panel 36. This makes it easier to screw the fan guard 42, and the fan guard 42 can be easily attached to the front panel 36.
　また、本実施例に係るヒートポンプサイクル装置１の室外機２において、前面パネル３６は、該前面パネル３６の一部が筐体３０の背面側に凹んだ凹部７１を有し、凹部７１に支持部７０が形成されるため、前面パネル３６の一部を背面側に凹ませることで容易に支持部７０を形成することができる。 In addition, in the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment, the front panel 36 has a recess 71 in which a portion of the front panel 36 is recessed toward the rear side of the housing 30, and the support portion 70 is formed in the recess 71, so that the support portion 70 can be easily formed by recessing a portion of the front panel 36 toward the rear side.
　また、本実施例に係るヒートポンプサイクル装置１の室外機２において、ファンガード４２は、筐体３０の前面パネル３６の吹出口４１を覆う前面部４２０と、筐体３０の左側面側の一部を覆う左側面部４２１とを備えて一体に形成され、凹部７１の奥行寸法は、前面部４２０を該凹部７１の内部に収めることができる寸法であるため、ファンガード４２を前面パネル３６における第１前面部３６Ａの前端部３６Ａ１とほぼ面一に位置決めした状態で固定することができる。従って、ファンガード４２と前面パネル３６とほぼ同一面になることで全体の一体感を高め、室外機２のデザイン性を向上させることができる。なお、室外機２のデザイン性を重視しない場合には、ファンガード４２は前面パネル３６に対して出っ張って配置されてもよい。 In the outdoor unit 2 of the heat pump cycle device 1 according to this embodiment, the fan guard 42 is integrally formed with a front portion 420 that covers the air outlet 41 of the front panel 36 of the housing 30, and a left side portion 421 that covers part of the left side of the housing 30, and the depth dimension of the recess 71 is such that the front portion 420 can be accommodated inside the recess 71, so the fan guard 42 can be fixed in a state where it is positioned almost flush with the front end portion 36A1 of the first front portion 36A of the front panel 36. Therefore, by having the fan guard 42 and the front panel 36 almost flush with each other, the overall sense of unity is enhanced, and the design of the outdoor unit 2 can be improved. Note that if the design of the outdoor unit 2 is not important, the fan guard 42 may be positioned to protrude from the front panel 36.
　上記した構成要素には、当業者が容易に想定できるもの、実質的に同一のものを含む。さらに、上記した構成は適宜組み合わせが可能である。また、本発明の要旨を逸脱しない範囲において構成の種々の省略、置換または変更が可能である。例えば、本実施例では、ファンガード４２が取り付けられる前面パネル３６は、筐体３０の前面の一部を形成する第１前面部３６Ａと、筐体３０の左側面の一部を形成する第１左側面部３６Ｂとを一体に備えた構成として説明したが、前面パネルは前面部を少なくとも備えていれば、側面部を備えることを要しない。また、本実施例では、ファンガード４２は、下突起部として機能する位置決め突起部６１４（第１下突起部）と下ねじ止め部６１２（第２下突起部）とを備えた構成として説明したが、少なくとも位置決め突起部６１４を備えていれば、下ねじ止め部６１２を備えることを要しない。 The above-mentioned components include those that a person skilled in the art can easily imagine and those that are substantially the same. Furthermore, the above-mentioned configurations can be appropriately combined. Furthermore, various omissions, substitutions, or modifications of the configurations are possible within the scope of the gist of the present invention. For example, in this embodiment, the front panel 36 to which the fan guard 42 is attached is described as having a configuration that integrally includes a first front portion 36A that forms a part of the front surface of the housing 30 and a first left side portion 36B that forms a part of the left side surface of the housing 30, but the front panel does not need to have a side portion as long as it has at least a front portion. Furthermore, in this embodiment, the fan guard 42 is described as having a configuration that includes a positioning protrusion 614 (first lower protrusion) and a lower screw fastening portion 612 (second lower protrusion) that function as a lower protrusion, but as long as it has at least the positioning protrusion 614, it does not need to have the lower screw fastening portion 612.
