Description
油面計を有する圧縮機及び冷凍空調装置に関する。 The present invention relates to a compressor having an oil level gauge and a refrigeration air conditioner.
圧縮機及び冷凍空調装置の信頼性を確保するため、冷凍空調装置に搭載される圧縮機に油面計が設置される。冷凍空調装置の設置の際には、この油面計により圧縮機内の油面を確認しながら冷凍サイクルの配管長に応じて封入油量を調節する。図１に油面計を備えた圧縮機の模式図を示す。図１のように、密閉容器１の中には、圧縮機構部２及び電動機３が中心軸を貫通する駆動軸４に連結した状態で収納される。密閉容器１内には、圧縮機構部２の摺動部の潤滑及び冷却に使用される潤滑油による油面５が形成される。圧縮機に油面計６を設置する際には、圧縮機内の油量保持が確認できる位置及び冷凍空調装置搭載の際に視認しやすい位置に油面計６を設置する必要がある。 In order to ensure the reliability of the compressor and the refrigeration air conditioner, an oil level gauge is installed in the compressor mounted on the refrigeration air conditioner. When installing the refrigeration air conditioner, the oil level is adjusted according to the piping length of the refrigeration cycle while checking the oil level in the compressor with this oil level gauge. FIG. 1 shows a schematic diagram of a compressor equipped with an oil level gauge. As shown in FIG. 1, the compression container 2 and the electric motor 3 are accommodated in the sealed container 1 in a state of being connected to a drive shaft 4 penetrating the central shaft. An oil surface 5 made of lubricating oil used for lubricating and cooling the sliding portion of the compression mechanism portion 2 is formed in the sealed container 1. When the oil level gauge 6 is installed in the compressor, it is necessary to install the oil level gauge 6 at a position where the oil amount retention in the compressor can be confirmed and at a position where the oil level gauge can be easily seen when the refrigeration air conditioner is installed.
従来の冷凍空調装置用圧縮機は、例えば文献１のような横形スクロール圧縮機においては、油面計の表示面は圧縮機の中心軸と平行に設置される。油面計の表示面を圧縮機の中心軸と平行に設置すると、圧縮機の中心軸が冷凍空調装置の前面と平行になるよう圧縮機を設置した際に、圧縮機の油面を視認しやすい。 In a conventional compressor for a refrigerating and air-conditioning apparatus, for example, in a horizontal scroll compressor as described in Document 1, the display surface of an oil level gauge is installed in parallel with the central axis of the compressor. If the display surface of the oil level gauge is installed parallel to the center axis of the compressor, when the compressor is installed so that the center axis of the compressor is parallel to the front of the refrigeration air conditioner, the oil level of the compressor is visually confirmed. Cheap.
一方、特許文献２のように、冷凍空調装置の省スペース化のため、横形圧縮機を圧縮機の中心軸が冷凍空調装置の前面に対して角度を有するように設置する場合がある。 On the other hand, as in Patent Document 2, in order to save space in the refrigeration air conditioner, the horizontal compressor may be installed such that the central axis of the compressor has an angle with respect to the front surface of the refrigeration air conditioner.
しかしながら、冷凍空調装置に搭載される油面計を設置した横形圧縮機において油面計の表示面を圧縮機の中心軸と平行に設置すると、特許文献２に記載のように冷凍空調装置の前面に対し角度をつけて圧縮機を設置した場合は、油面計表示面の視認性が悪化し、冷凍空調装置の前面に対する角度が大きくなるほど視認しづらくなる。 However, when the display surface of the oil level gauge is installed parallel to the central axis of the compressor in a horizontal compressor having an oil level gauge mounted on the refrigeration air conditioner, the front surface of the refrigeration air conditioner as described in Patent Document 2 is provided. However, when the compressor is installed at an angle, the visibility of the oil level indicator display surface is deteriorated, and the more the angle with respect to the front surface of the refrigeration air conditioner is increased, the more difficult it is to visually recognize.
本発明は、圧縮機の中心軸が冷凍空調装置の前面と平行になるよう圧縮機を設置した場合であっても、また、圧縮機の中心軸が冷凍空調装置の前面と角度を有するように設置した場合であっても、油面計表示面の視認性の悪化を抑制し、圧縮機配置の自由度を向上させることを課題とする。 In the present invention, even when the compressor is installed so that the central axis of the compressor is parallel to the front surface of the refrigeration air conditioner, the central axis of the compressor has an angle with the front surface of the refrigeration air conditioner. Even if it is a case where it installs, it makes it a subject to suppress the deterioration of the visibility of an oil level indicator display surface, and to improve the freedom degree of compressor arrangement | positioning.

The angle θ formed with the central axis is 0 ° <θ <90 °. Further, an angle θ2 formed by the central axis of the hermetic container of the horizontal compressor and the front surface of the refrigeration air conditioner is set to 0 ° <θ2 ≦ 90 °.
本発明によれば、圧縮機の中心軸が冷凍空調装置の前面と平行になるよう圧縮機を設置した場合であっても、また、圧縮機の中心軸が冷凍空調装置の前面と角度を有するように設置した場合であっても、油面計表示面の視認性の悪化を抑制し、圧縮機配置の自由度を向上させることができる。 According to the present invention, even when the compressor is installed such that the central axis of the compressor is parallel to the front surface of the refrigeration air conditioner, the central axis of the compressor has an angle with the front surface of the refrigeration air conditioner. Even if it is a case where it installs in this way, the deterioration of the visibility of an oil level indicator display surface can be suppressed and the freedom degree of compressor arrangement | positioning can be improved.

図３は本発明を適用した横形圧縮機を上から見た平面図であり、図２の横形圧縮機を上から見た平面図を上から見た平面図である。図３に示すように、本実施例では、油面計６の表示面は油面計６の表示面と圧縮機７の中心軸７ａ（圧縮機７の密閉容器１７の中心軸７ａ）とのなす角θを０°＜θ＜９０°となるよう油面計を設置する。このように油面計を配置することにより、配置の変化に対しても油面計の視認性が向上し、同一の圧縮機を搭載する際の配置の自由度を向上させることができる。 FIG. 3 is a plan view of a horizontal compressor to which the present invention is applied as viewed from above, and a plan view of the horizontal compressor of FIG. 2 as viewed from above. As shown in FIG. 3, in the present embodiment, the display surface of the oil level gauge 6 is the display surface of the oil level gauge 6 and the central axis 7a of the compressor 7 (the central axis 7a of the sealed container 17 of the compressor 7). An oil level gauge is installed so that the angle θ formed is 0 ° <θ <90 °. By arranging the oil level gauge in this manner, the visibility of the oil level gauge can be improved even with respect to a change in arrangement, and the degree of freedom in arrangement when the same compressor is mounted can be improved.
一方、本発明の横形圧縮機は、図４、図５に示すように油面計６の表示面を配置してもよい。図４は、横形圧縮機に本発明を適用した横形圧縮機の横断面図である。 On the other hand, the horizontal compressor of the present invention may have a display surface of the oil level gauge 6 as shown in FIGS. FIG. 4 is a cross-sectional view of a horizontal compressor in which the present invention is applied to a horizontal compressor.
圧縮機構部８は、固定スクロール９、旋回スクロール１０、フレーム１１、自転防止機構１２、及び、駆動軸１３を備える。固定スクロール９は、円板状の底板９ａ、及び、底板９ａに直立する渦巻状のラップ９ｂを有し、中心部分に吐出口１４、外周部に吸入口１５を配置する。旋回スクロール１０は、円板状の平板部１０ａ、平板部１０ａに直立し固定スクロールの渦巻状ラップ９ｂと噛み合うように成形された渦巻状のラップ１０ｂ、及び、平板の反ラップ面に形成されたボス１０ｃを有し、ボス１０ｃの内径部には軸受部１０ｄを有する。フレーム１１は、中央部に軸受部１１ａを有し、この軸受部１１ａに駆動軸１３が支持される。フレーム１１には固定スクロールの平板部９ｃが複数本のボルトにより固定される。駆動軸先端の偏芯軸部１３ａは旋回スクロールの軸受１０ｄに挿入され、自転防止機構１２と偏芯軸１３ａの回転により、旋回スクロール１０は固定スクロール９に対して自転することなく旋回運動をする。駆動軸１３には電動機１６の回転子１６ａが直結され、固定子１６ｂはフレーム１１内に固定される。 The compression mechanism unit 8 includes a fixed scroll 9, a turning scroll 10, a frame 11, a rotation prevention mechanism 12, and a drive shaft 13. The fixed scroll 9 has a disk-shaped bottom plate 9a and a spiral wrap 9b that stands upright on the bottom plate 9a, and a discharge port 14 is disposed in the center portion and a suction port 15 is disposed on the outer peripheral portion. The orbiting scroll 10 is formed on a disc-shaped flat plate portion 10a, a spiral wrap 10b which is formed upright on the flat plate portion 10a and meshes with the spiral wrap 9b of the fixed scroll, and a flat anti-wrap surface. A boss 10c is provided, and a bearing portion 10d is provided on an inner diameter portion of the boss 10c. The frame 11 has a bearing portion 11a at the center, and the drive shaft 13 is supported by the bearing portion 11a. A flat scroll portion 9c of a fixed scroll is fixed to the frame 11 with a plurality of bolts. The eccentric shaft portion 13a at the tip of the drive shaft is inserted into the bearing 10d of the orbiting scroll, and the orbiting scroll 10 orbits without rotating with respect to the fixed scroll 9 by the rotation of the rotation preventing mechanism 12 and the eccentric shaft 13a. . A rotor 16 a of an electric motor 16 is directly connected to the drive shaft 13, and the stator 16 b is fixed in the frame 11.
固定スクロール９の吸入口１５には、密閉容器１７を形成する蓋１７ｂを貫通する吸入管１８が接続される。低圧の冷媒ガスは、この吸入管１８から吸入されて、固定スクロール９の渦巻状ラップ９ｂと旋回スクロールの渦巻状ラップ１０ｂが噛み合うことにより形成される密閉空間である圧縮室１９に入る。その後、駆動軸１３の回転による旋回スクロール１０の旋回運動により圧縮室１９の容積が減じることにより冷媒ガスが圧縮され、さらに圧力を高めた冷媒ガスは、中央部分の吐出口１４から、吸入管１８が貫通する蓋１７ｂにより形成される吐出空間２０ａに向けて吐出される。吐出空間２０ａに吐出された冷媒ガスは、フレーム１１と密閉容器１７により吐出室２０に形成された通路２０ｂを通過し、フレーム１１、固定子１６ｂ、及び、回転子１６ａの間を通過し、蓋１７ｃにより形成される吐出室２０ｃと連通した後に、密閉容器１７を形成する円筒状のケーシング１７ａに取付けられた吐出管２１から吐出される。 A suction pipe 18 that passes through a lid 17 b that forms a sealed container 17 is connected to the suction port 15 of the fixed scroll 9. The low-pressure refrigerant gas is sucked from the suction pipe 18 and enters the compression chamber 19 which is a sealed space formed by meshing the spiral wrap 9b of the fixed scroll 9 and the spiral wrap 10b of the orbiting scroll. Thereafter, the refrigerant gas is compressed by reducing the volume of the compression chamber 19 due to the orbiting motion of the orbiting scroll 10 by the rotation of the drive shaft 13, and the refrigerant gas whose pressure is further increased is discharged from the discharge port 14 in the central portion through the suction pipe 18. Is discharged toward the discharge space 20a formed by the lid 17b penetrating therethrough. The refrigerant gas discharged into the discharge space 20a passes through the passage 20b formed in the discharge chamber 20 by the frame 11 and the sealed container 17, passes between the frame 11, the stator 16b, and the rotor 16a. After communicating with the discharge chamber 20c formed by 17c, the liquid is discharged from the discharge pipe 21 attached to the cylindrical casing 17a forming the sealed container 17.
吸入管１８が貫通しない蓋１７ｃには、密閉容器１７下方に溜まる油の油面を確認するための油面計２２が設けられる。油面計２２は圧縮機内の油面のレベルを確認できる高さに、表示面が圧縮機を設置した際に、設置面（水平面）に対して垂直になるよう設置される。 The lid 17c through which the suction pipe 18 does not penetrate is provided with an oil level gauge 22 for confirming the oil level of the oil accumulated below the sealed container 17. The oil level gauge 22 is installed at a height at which the level of the oil level in the compressor can be confirmed so that the display surface is perpendicular to the installation surface (horizontal plane) when the compressor is installed.
図５は本発明を適用した横形圧縮機を上から見た平面図であり、図４の横形圧縮機を上から見た平面図を上から見た平面図である。図５に示すように、本実施例では、油面計２２の表示面は油面計２２の表示面と横形スクロール圧縮機２３の中心軸２３ａ（圧縮機７の密閉容器の中心軸２３ａ）とのなす角θを０°＜θ＜９０°となるよう油面計を設置する。このように油面計を配置することにより、配置の変化に対しても油面計の視認性が向上し、同一の圧縮機を搭載する際の配置の自由度を向上させることができる。 FIG. 5 is a plan view of a horizontal compressor to which the present invention is applied as seen from above, and a plan view of the horizontal compressor of FIG. 4 as seen from above. As shown in FIG. 5, in the present embodiment, the display surface of the oil level gauge 22 includes the display surface of the oil level gauge 22, the central axis 23 a of the horizontal scroll compressor 23 (the central axis 23 a of the sealed container of the compressor 7), An oil level gauge is installed so that the angle θ between the angle θ is 0 ° <θ <90 °. By arranging the oil level gauge in this manner, the visibility of the oil level gauge can be improved even with respect to a change in arrangement, and the degree of freedom in arrangement when the same compressor is mounted can be improved.
ここで、本実施例の横形圧縮機では、油面計の表示面と密閉容器の中心軸とのなす角θを０°＜θ＜９０°とすることにより、圧縮機の中心軸が冷凍空調装置の前面と平行になるよう圧縮機を設置した場合であっても、また、圧縮機の中心軸が冷凍空調装置の前面と角度を有するように設置した場合であっても、油面計表示面の視認性の悪化を抑制し、圧縮機配置の自由度を向上させることができる。その理由について以下に説明する。 Here, in the horizontal compressor of the present embodiment, the angle θ formed between the display surface of the oil level gauge and the central axis of the sealed container is set to 0 ° <θ <90 °, whereby the central axis of the compressor is refrigerated and air-conditioned. Even when the compressor is installed so that it is parallel to the front of the equipment, or even when the compressor is installed so that the central axis of the compressor is at an angle with the front of the refrigeration air conditioner, the oil level gauge display Deterioration of the visibility of the surface can be suppressed, and the degree of freedom of compressor arrangement can be improved. The reason will be described below.
図６は、本実施例の横形圧縮機を搭載した冷凍空調装置を上から見た平面図である。図６において、横形圧縮機２４は冷凍空調装置２５の圧縮機設置面２５ａに、冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａ（横形圧縮機２４の密閉容器の中心軸２４ａ）が平行になるように設置される。冷凍空調装置２５の設置時において、方向２６より横形圧縮機２４の油面計２２を観察する。 FIG. 6 is a plan view of a refrigerating and air-conditioning apparatus equipped with the horizontal compressor of the present embodiment as viewed from above. In FIG. 6, the horizontal compressor 24 has a compressor installation surface 25 a of the refrigeration air conditioner 25, a front surface portion 25 b of the refrigeration air conditioner, and a central axis 24 a of the horizontal compressor 24 (a central axis 24 a of the sealed container of the horizontal compressor 24). Are installed in parallel. The oil level gauge 22 of the horizontal compressor 24 is observed from the direction 26 when the refrigeration air conditioner 25 is installed.
一方、図７は、本実施例の横形圧縮機を搭載した冷凍空調装置を上から見た平面図である。図７において、横形圧縮機２４は冷凍空調装置２５の圧縮機設置面２５ａに、冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａとのなす角θ２が０°＜θ２＜９０°となるよう設置される。冷凍空調装置２５の設置時において、方向２６より横形圧縮機２４の油面計２２を観察する。 On the other hand, FIG. 7 is a plan view of the refrigerating and air-conditioning apparatus equipped with the horizontal compressor of this embodiment as seen from above. In FIG. 7, the horizontal compressor 24 has an angle θ <b> 2 formed by the front surface portion 25 b of the refrigeration air conditioner and the central axis 24 a of the refrigeration air conditioner 25 on the compressor installation surface 25 a of the refrigeration air conditioner 25, 0 ° <θ2 <90 °. It is installed to become. The oil level gauge 22 of the horizontal compressor 24 is observed from the direction 26 when the refrigeration air conditioner 25 is installed.
油面計の表示面と密閉容器の中心軸とのなす角θを０°＜θ＜９０°とすることにより、図６に示すように、横形圧縮機２４を冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａを平行（冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａとのなす角θ２＝０°）に配置しても、油面計表示面が方向２６に対して所定の角度を有するので、方向２６から油面計表示面を確認することができる。 By setting the angle θ formed between the display surface of the oil level gauge and the central axis of the sealed container to be 0 ° <θ <90 °, the horizontal compressor 24 is connected to the front portion 25b of the refrigeration air conditioner as shown in FIG. Even if the central axis 24a of the horizontal compressor 24 is arranged in parallel (the angle θ2 = 0 ° formed by the front surface portion 25b of the refrigeration air conditioner and the central axis 24a of the horizontal compressor 24), the oil level gauge display surface is in the direction 26. Therefore, the oil level gauge display surface can be confirmed from the direction 26.
一方、油面計の表示面と密閉容器の中心軸とのなす角θを０°＜θ＜９０°とすることにより、図７に示すように、冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａとのなす角θ２を０°＜θ２＜９０°となるよう配置しても、油面計表示面が方向２６に対して所定の角度を有するので、方向２６から油面計表示面を確認することができる。 On the other hand, by setting the angle θ formed between the display surface of the oil level gauge and the central axis of the sealed container to 0 ° <θ <90 °, as shown in FIG. 7, the front portion 25b of the refrigeration air conditioner and the horizontal compressor Since the oil level gauge display surface has a predetermined angle with respect to the direction 26 even if the angle θ2 formed by the central axis 24a of 24 is 0 ° <θ2 <90 °, the oil level gauge The display surface can be confirmed.
さらに、油面計の表示面と密閉容器の中心軸とのなす角θを０°＜θ＜９０°とすることにより、図示していないが、横形圧縮機２４を冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａを垂直（冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａとのなす角θ２＝９０°）に配置しても、油面計表示面が方向２６に対して所定の角度を有するので、方向２６から油面計表示面を確認することができる。 Further, by setting the angle θ formed between the display surface of the oil level gauge and the central axis of the sealed container to be 0 ° <θ <90 °, the horizontal compressor 24 is connected to the front surface portion 25b of the refrigeration air conditioner, although not shown. Even if the central axis 24a of the horizontal compressor 24 and the central axis 24a of the horizontal compressor 24 are arranged vertically (angle θ2 = 90 ° between the front surface portion 25b of the refrigeration air conditioner and the central axis 24a of the horizontal compressor 24), the oil level gauge display surface is oriented. Since it has a predetermined angle with respect to 26, the oil level gauge display surface can be confirmed from the direction 26.
図１に示す従来技術のように、油面計の表示面を圧縮機の中心軸と平行に設置すると、横形圧縮機を冷凍空調装置の前面部と横形圧縮機の中心軸を平行（冷凍空調装置の前面部と横形圧縮機の中心軸とのなす角θ２＝０°）に配置した場合に最も視認性が高く、本実施例の横形圧縮機（油面計の表示面と密閉容器の中心軸とのなす角θが０°＜θ＜９０°）の場合よりも視認性は高い。しかしながら、図１に示す従来技術のように、油面計の表示面を圧縮機の中心軸と平行に設置すると、冷凍空調装置の前面部と横形圧縮機の中心軸とのなす角θ２が大きくなるにつれて視認性が悪化し、θ２＝９０°では油面計の表示面を全く確認できなくなる。 When the display surface of the oil level gauge is installed parallel to the center axis of the compressor as in the prior art shown in FIG. 1, the horizontal compressor is parallel to the front portion of the refrigeration air conditioner and the center axis of the horizontal compressor (refrigeration air conditioning The horizontal compressor (the display surface of the oil level gauge and the center of the airtight container) of this embodiment has the highest visibility when it is arranged at an angle θ2 = 0 ° between the front surface of the apparatus and the central axis of the horizontal compressor. The visibility is higher than when the angle θ formed with the axis is 0 ° <θ <90 °. However, if the display surface of the oil level gauge is installed in parallel with the central axis of the compressor as in the prior art shown in FIG. 1, the angle θ2 formed by the front portion of the refrigeration air conditioner and the central axis of the horizontal compressor is large. Visibility deteriorates as it becomes, and when θ2 = 90 °, the display surface of the oil level gauge cannot be confirmed at all.
これに対して、本実施例の横形圧縮機では、油面計の表示面と密閉容器の中心軸とのなす角θを０°＜θ＜９０°とすることにより、例えば、冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａとのなす角θ２が小さい場合（例えば、が横形圧縮機２４を冷凍空調装置の前面部２５ｂと横形圧縮機２４の中心軸２４ａが平行の場合）は図１に示す従来技術よりも視認性が低下するが、一方、０°＜θ≦９０°の角度で視認性が改善し得る。 On the other hand, in the horizontal compressor of the present embodiment, the angle θ formed between the display surface of the oil level gauge and the central axis of the sealed container is set to 0 ° <θ <90 °, for example, When the angle θ2 formed by the front portion 25b and the central axis 24a of the horizontal compressor 24 is small (for example, when the horizontal compressor 24 is parallel to the front portion 25b of the refrigeration air conditioner and the central axis 24a of the horizontal compressor 24). Is less visible than the prior art shown in FIG. 1, but on the other hand, the visibility can be improved at an angle of 0 ° <θ ≦ 90 °.
以上説明したように、本実施例の横形圧縮機は、作動流体を圧縮する圧縮機構部と、圧縮機構部を駆動する電動機と、一方に圧縮機構部を連結し他方に電動機を連結する駆動軸と、圧縮機構部、駆動軸、及び、電動機を水平方向に配置して収納する密閉容器と、密閉容器に溜まる油の油面レベルを確認するための油面計と、を備え、油面計の表示面と密閉容器の中心軸とのなす角θを０°＜θ＜９０°とする。また、このとき、横形圧縮機の密閉容器の中心軸と冷凍空調装置の前面とのなす角θ２を０°＜θ２≦９０°として横形圧縮機を配置する。これにより、圧縮機の中心軸が冷凍空調装置の前面と平行になるよう圧縮機を設置した場合であっても、また、圧縮機の中心軸が冷凍空調装置の前面と角度を有するように設置した場合であっても、油面計表示面の視認性の悪化を抑制し、圧縮機配置の自由度を向上させることができる。 As described above, the horizontal compressor according to the present embodiment includes a compression mechanism that compresses the working fluid, an electric motor that drives the compression mechanism, and a drive shaft that connects the compression mechanism to one side and the electric motor to the other. And an oil level gauge for confirming the oil level of the oil accumulated in the sealed container, and a sealed container for storing the compression mechanism portion, the drive shaft, and the electric motor in a horizontal direction. An angle θ formed by the display surface of the closed container and the central axis of the sealed container is 0 ° <θ <90 °. At this time, the horizontal compressor is arranged such that the angle θ2 formed by the central axis of the hermetic container of the horizontal compressor and the front surface of the refrigeration air conditioner is 0 ° <θ2 ≦ 90 °. As a result, even if the compressor is installed so that the center axis of the compressor is parallel to the front surface of the refrigeration air conditioner, the center axis of the compressor is installed so that it has an angle with the front surface of the refrigeration air conditioner Even if it is, it can suppress the deterioration of the visibility of an oil level indicator display surface, and can improve the freedom degree of compressor arrangement | positioning.
