Description

本発明は、冷媒の圧縮を行う圧縮機に関するものである。   The present invention relates to a compressor that compresses a refrigerant.

従来の密閉型圧縮機は図８に示すように、圧縮機構３と電動機４とを溶接構造のハウジング２に密閉して形成される。この密閉型圧縮機は、冷媒が漏洩せず、水分の侵入等のおそれも無いことから高い信頼性を有し、空調機や冷蔵庫に広く用いられている。   As shown in FIG. 8, a conventional hermetic compressor is formed by sealing a compression mechanism 3 and an electric motor 4 in a housing 2 having a welded structure. This hermetic compressor has high reliability because the refrigerant does not leak and there is no risk of moisture intrusion, and is widely used in air conditioners and refrigerators.

上記密閉型圧縮機では、ハウジング２内の電動機４に電力を供給する必要がある。このため、耐圧性と気密性に優れたいわゆる密封端子８をハウジングに溶接し、この密封端子を介して電動機へ電力を供給している（例えば、特許文献１参照）。   In the hermetic compressor, it is necessary to supply electric power to the electric motor 4 in the housing 2. For this reason, a so-called sealed terminal 8 excellent in pressure resistance and airtightness is welded to the housing, and electric power is supplied to the electric motor through the sealed terminal (see, for example, Patent Document 1).

また、上記密閉型圧縮機では、ハウジング内に貯留する冷凍機油を圧縮機構や軸受等に供給して潤滑を行うようにしている。通常、ハウジング内の冷凍機油は、圧縮されたガス冷媒と共に圧縮機から吐出され、冷媒回路を循環して再び圧縮機に戻るため、ハウジングにおける冷凍機油の貯留量は確保されるが、運転状態によっては冷凍機油の貯留量が変動し、過不足となって、性能低下や潤滑不良に至る危険がある。   Further, in the hermetic compressor, the refrigerating machine oil stored in the housing is supplied to a compression mechanism, a bearing, and the like for lubrication. Normally, the refrigerating machine oil in the housing is discharged from the compressor together with the compressed gas refrigerant, circulates through the refrigerant circuit, and returns to the compressor again. The storage amount of refrigerating machine oil fluctuates and becomes excessive and insufficient, leading to the risk of performance degradation and poor lubrication.

上述の問題に対し、従来より、油面検出センサ等をハウジング内部に設置し、油面位置を検出、冷凍機油の貯留量を検知して、その信号を信号線を通じて、密閉端子から外部へ取り出すことが知られている。或いは、特許文献２では直接密閉端子にセンサ等を設置、信号線を通さず、外部へ検出信号を取り出すという提案がなされている。
特開平６−１５９２７４号公報 特開２００１−１２３５１号公報 In order to solve the above-mentioned problems, conventionally, an oil level detection sensor or the like is installed inside the housing, the oil level position is detected, the amount of refrigerating machine oil is detected, and the signal is taken out from the sealed terminal to the outside through a signal line. It is known. Alternatively, Patent Document 2 proposes that a sensor or the like is installed directly on the sealed terminal, and the detection signal is taken out without passing the signal line.
JP-A-6-159274 JP 2001-12351 A

しかしながら、前記従来の構成では、ハウジング上部に密封端子を取付け、油面位置の油面検出部材と密封端子を信号線で結び信号を取り出す為、信号線の取り扱いが煩雑であり、絶縁不良といった信頼性確保に問題が発生したり、組立性において問題があった。又、油面位置のハウジング側壁に直接信号取り出し用密閉端子を取り付ける構成では、側壁は円筒状となっており、取付にあたり歪み等による気密不良や組立工程中での接触破損による気密不良を招くおそれがあった。   However, in the conventional configuration, since the sealing terminal is attached to the upper part of the housing and the oil level detecting member and the sealing terminal at the oil level position are connected by the signal line and the signal is taken out, the handling of the signal line is complicated, and the reliability such as poor insulation is obtained. There was a problem in securing the safety, and there was a problem in assembly. Further, in the configuration in which the signal extraction sealed terminal is directly attached to the housing side wall at the oil level, the side wall has a cylindrical shape, which may lead to airtight failure due to distortion or the like or contact failure during assembly process during mounting. was there.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、圧縮機の構成を簡素に維持しつつハウジング内における油面の位置を確実に検出し、併せて、かかる圧縮機を用いて冷凍装置の信頼性向上を図ることにある。   The present invention has been made in view of such a point, and an object of the present invention is to reliably detect the position of the oil level in the housing while maintaining the configuration of the compressor in a simple manner, and to perform such compression. The purpose is to improve the reliability of the refrigeration system using a machine.

本発明の講じた手段は、ハウジング内の油面の位置を検出する検出部材を上記圧縮機構の油面検出位置に設置し、その油面検出信号を伝える信号線を、ハウジング上部に設けられた油面検出信号取り出し用密封端子で外部に取り出す様に構成した。また、この信号線を、絶縁され且つ耐冷媒性と耐熱性に優れた材質で被覆された線を使用するか、耐冷媒性と耐熱性に優れた材質の保護管に信号線を通すようにした。又、上記信号線を電動機とハウジングの間のガス通路に通すこと、或いは、電動機の固定子の一部に上下に穴を開け信号線を通し、圧縮機構部から上部の密閉端子を信号線で結ぶようにした。   According to the present invention, a detection member for detecting the position of the oil level in the housing is installed at the oil level detection position of the compression mechanism, and a signal line for transmitting the oil level detection signal is provided on the upper part of the housing. The oil level detection signal is taken out by a sealed terminal. Also, use a wire that is insulated and covered with a material that is excellent in refrigerant resistance and heat resistance, or pass the signal wire through a protective tube made of a material that is excellent in refrigerant resistance and heat resistance. did. Also, let the signal line pass through the gas passage between the motor and the housing, or make a hole in the upper and lower parts of the stator of the motor to pass the signal line, and connect the upper sealed terminal from the compression mechanism part with the signal line. I tried to tie it.

上記の解決手段では、電動機４で圧縮機構３を駆動すると、密閉型圧縮機１にガス冷媒が吸入され、圧縮後に吐出される。その間、ハウジング２の底部に溜まる冷凍機油が圧縮機構３や軸受等に供給され、潤滑が行われる。冷凍機油は、圧縮された冷媒ガスと共に密閉型圧縮機１から吐出される。従って、密閉型圧縮機１の運転中には、ハウジング２内に貯留する冷凍機油の量が変化し、油面９の位置が変動する。   In the above solution, when the compression mechanism 3 is driven by the electric motor 4, the gas refrigerant is sucked into the hermetic compressor 1 and discharged after compression. Meanwhile, the refrigerating machine oil that accumulates at the bottom of the housing 2 is supplied to the compression mechanism 3 and the bearings, and lubrication is performed. The refrigerating machine oil is discharged from the hermetic compressor 1 together with the compressed refrigerant gas. Therefore, during operation of the hermetic compressor 1, the amount of refrigerating machine oil stored in the housing 2 changes, and the position of the oil level 9 changes.

油面検出部材１０を圧縮機構３の油面検出の最適位置に取り付けてあり、その信号は信号線１２でハウジング２上部の密封端子１１と結線され、ハウジング２内における油面９の位置を検出し、検出部１０の検出信号を密封端子１１を通じてハウジング２の外に取り出される。   The oil level detecting member 10 is attached to the optimum position for detecting the oil level of the compression mechanism 3, and the signal is connected to the sealing terminal 11 at the upper part of the housing 2 by the signal line 12 to detect the position of the oil level 9 in the housing 2. Then, the detection signal of the detection unit 10 is taken out of the housing 2 through the sealed terminal 11.

また、この信号線１２を、絶縁され且つ耐冷媒性と耐熱性に優れた材質で被覆された線を使用するか、耐冷媒性と耐熱性に優れた材質の保護管に信号線を通すようにしており、或いは、電動機の固定子６の一部に穴１７を開け信号線１２を通しており、信号線の圧縮機組立中の接触等による傷や破損を低減できる。また、運転中の振動等による信号線の破損や絶縁不良を低減できる。   Further, the signal wire 12 may be insulated and covered with a material excellent in refrigerant resistance and heat resistance, or the signal wire may be passed through a protective tube made of a material excellent in refrigerant resistance and heat resistance. Alternatively, a hole 17 is formed in a part of the stator 6 of the motor and the signal line 12 is passed therethrough, so that damage or breakage due to contact of the signal line during assembly of the compressor can be reduced. In addition, signal line breakage and insulation failure due to vibration during operation can be reduced.

上記の解決手段によれば、信号線の圧縮機組立中の接触等による傷や破損を低減でき、また、運転中の振動等による信号線の破損や絶縁不良を低減でき、また、ハウジングの気密性や耐圧性を損なうことなく確実に油面検出部材の取り付けを行うことができ、本来必要な圧縮機構部に対する油面位置が、組立中の不良や運転中の不良発生の低減ができ、密閉型圧縮機の信頼性が向上できる。   According to the above solution, it is possible to reduce damage and breakage due to contact of the signal line during compressor assembly, etc., to reduce damage and insulation failure of the signal line due to vibration during operation, etc. The oil level detection member can be securely attached without impairing the performance and pressure resistance, and the oil level position with respect to the compression mechanism part, which is originally required, can reduce the occurrence of defects during assembly and operation, and is sealed The reliability of the mold compressor can be improved.

本願第１の発明は、電動機４とこれによって駆動される圧縮機構３とがハウジング２内に収納され、ハウジング２内に貯留する冷凍機油１７により潤滑される密閉型圧縮機において、ハウジング内の油面９の位置を検出する検出部材１０を圧縮機構の油面検出の最適位置に取り付け、その油面の信号を信号線１２を通して、電動機上部のハウジングの側面又は上面に設けられた専用密封端子１１を通じて外部に取り出す様に構成した。これにより、圧縮機構部３に必要とされる油面を確実に検出でき、且つ、外部の油面制御部へ情報を確実に伝達でき信頼性が向上できる。   The first invention of the present application is a hermetic compressor in which the electric motor 4 and the compression mechanism 3 driven by the electric motor 4 are housed in the housing 2 and lubricated by the refrigerating machine oil 17 stored in the housing 2. A detection member 10 for detecting the position of the surface 9 is attached to an optimum position for detecting the oil level of the compression mechanism, and a signal of the oil level is passed through a signal line 12 to a dedicated sealed terminal 11 provided on the side surface or the upper surface of the housing above the motor. It was configured to be taken out through. As a result, the oil level required for the compression mechanism unit 3 can be reliably detected, and information can be reliably transmitted to the external oil level control unit, thereby improving reliability.

本願第２の発明は、第１の発明の密閉型圧縮機において、その信号線１２を絶縁され且つ耐冷媒性と耐熱性に優れた材質で周囲を被覆した被覆線を使用し構成した。   According to a second aspect of the present invention, in the hermetic compressor according to the first aspect, the signal line 12 is formed by using a covered wire that is insulated and coated with a material excellent in refrigerant resistance and heat resistance.

又、本願第３の発明は、第１の発明の密閉型圧縮機において、耐冷媒性と耐熱性に優れた材質の保護管１９にその信号線１２を通し構成した。これらにより、圧縮機の組立中や空調機等の本体運転中の信号線の破損や絶縁不良を軽減できる。   In the third aspect of the present invention, in the hermetic compressor of the first aspect, the signal line 12 is configured to pass through the protective tube 19 made of a material excellent in refrigerant resistance and heat resistance. As a result, it is possible to reduce signal line breakage and insulation failure during assembly of the compressor and operation of the main body of the air conditioner or the like.

第４の発明は、第１、２、３の発明の密閉型圧縮機において、信号線１２を電動機４とハウジング２の間のガス又は油の流通路１３に通すよう構成した。 これにより、従来構造を変更することなく、組立製も損なわず、且つ、圧縮機の組立中や空調機等の本体運転中の信号線の破損や絶縁不良も軽減できる。   According to a fourth invention, in the hermetic compressor of the first, second, and third inventions, the signal line 12 is configured to pass through a gas or oil flow passage 13 between the electric motor 4 and the housing 2. As a result, the conventional structure is not changed, the assembly is not impaired, and the breakage of the signal line and the insulation failure during the assembly of the compressor and the operation of the main body such as the air conditioner can be reduced.

第５の発明は、第１、２、３の発明の密閉型圧縮機において、電動機の固定子の一部に電動機を境にした下部の圧縮機構部の空間とハウジングの上部空間を連通するよう穴１７を開け、その穴に信号線１２を通すよう構成した。この穴は、信号線が容易に通る大きさであって、円形でなくてもよい。これにより、信号線の取り扱いが容易になり、固定子の鋼板作成用金型を一部変更するだけで、組立製も損なわず、且つ、圧縮機の組立中や空調
機等の本体運転中の信号線の破損や絶縁不良も軽減できる。 According to a fifth aspect of the invention, in the hermetic compressor of the first, second, and third aspects of the invention, the space of the lower compression mechanism section and the upper space of the housing are communicated with a part of the stator of the electric motor. A hole 17 was formed, and the signal line 12 was passed through the hole. This hole has a size that allows the signal line to pass through easily and does not have to be circular. As a result, handling of the signal line is facilitated, and only a part of the mold for making the steel plate of the stator is changed, the assembly is not impaired, and the compressor is being assembled or the air conditioner is being operated. Damage to signal lines and poor insulation can be reduced.

And the information can be reliably transmitted to the external oil level control unit, and the reliability can be improved.

（実施の形態１）
以下、本発明の実施形態１を図面に基づいて詳細に説明する。 (Embodiment 1)
Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to the drawings.

図１は本発明の第１の実施の形態における油面検出部材１０を圧縮機構３の側壁に設けられている密閉型圧縮機を示す図である。   FIG. 1 is a view showing a hermetic compressor in which an oil level detection member 10 according to a first embodiment of the present invention is provided on a side wall of a compression mechanism 3.

図１において、圧縮機は、円筒容器状のハウジング２に圧縮機構３と電動機４とを収納して形成され、いわゆる高圧ドーム型に構成されている。ハウジング２の上端部には、圧縮したガス冷媒を送り出す吐出管１が設けられている。   In FIG. 1, the compressor is formed by housing a compression mechanism 3 and an electric motor 4 in a cylindrical container-like housing 2, and is configured as a so-called high-pressure dome shape. A discharge pipe 1 that sends out a compressed gas refrigerant is provided at the upper end of the housing 2.

上記圧縮機構３は、いわゆるローリングピストン型に構成され、ハウジング２に固定されている。圧縮機構３には、ガス冷媒を送り込む吸入管２０が接続されている。また、圧縮機構３は、駆動軸２１によって電動機４と連結され、電動機４によって回転駆動される。   The compression mechanism 3 is configured as a so-called rolling piston type and is fixed to the housing 2. A suction pipe 20 for feeding a gas refrigerant is connected to the compression mechanism 3. The compression mechanism 3 is connected to the electric motor 4 by the drive shaft 21 and is rotationally driven by the electric motor 4.

上記電動機４は、圧縮機構３の上方に配置されている。電動機４は、ハウジング２の上端部に溶接された電力用密封端子８と結線されている。この電動機４には、電力用密封端子８を介して電力が供給される。   The electric motor 4 is disposed above the compression mechanism 3. The electric motor 4 is connected to a power sealing terminal 8 welded to the upper end portion of the housing 2. Electric power is supplied to the electric motor 4 via a power sealing terminal 8.

上記駆動軸２１は、図外の遠心ポンプと給油路とを備え、圧縮機構３を貫通して設けられている。遠心ポンプは駆動軸２１の下端部に設けられ、駆動軸２１の回転に伴ってハウジング２の底に貯留する冷凍機油を汲み上げるように構成されている。一方、給油路は、駆動軸２１の内部にその軸方向に沿って形成され、遠心ポンプが汲み上げた冷凍機油を各摺動部分へ供給するよう構成されている。   The drive shaft 21 includes a centrifugal pump and an oil supply path (not shown) and is provided through the compression mechanism 3. The centrifugal pump is provided at the lower end of the drive shaft 21, and is configured to pump refrigeration oil stored in the bottom of the housing 2 as the drive shaft 21 rotates. On the other hand, the oil supply passage is formed inside the drive shaft 21 along the axial direction thereof, and is configured to supply the refrigerating machine oil pumped up by the centrifugal pump to each sliding portion.

図１に示すように、圧縮機の圧縮機構３には、油面検出部材１０である油面センサ２２が設けられている。この油面検出部材１０は、ハウジング２の下部であって、ハウジング２内における油面検出の最適位置になるよう、圧縮機構３等にボルト等によって取り付けられている。これにより、確実に油面位置の検出ができ、且つ、従来より電力供給用に使用していた密閉型端子を使用して信号を取り出せ、製造上の品質面の確保や市場での信頼性についての実績もあり、確実に信頼性が確保できる。   As shown in FIG. 1, the compression mechanism 3 of the compressor is provided with an oil level sensor 22 that is the oil level detection member 10. The oil level detection member 10 is attached to the compression mechanism 3 or the like with a bolt or the like so as to be at the optimum position for detecting the oil level in the housing 2 at the lower part of the housing 2. As a result, the oil level position can be reliably detected, and signals can be taken out using the sealed terminals that have been used for power supply from the past, ensuring manufacturing quality and reliability in the market. There is also a track record of ensuring reliability.

さらに、油面検出部材には信号線１２が結線され、その信号線を上記ハウジング２の上部シェルに設けられた専用の密閉端子１１に結線されている。この密閉端子を通じて、検出された信号は外部に取り出される。このとき、上記密閉端子１１は、図１では３本の端子としているが、必要に応じ２本の端子や４本端子等にしてもよい。又、電力供給用密閉端子８は通常３端子であるが、これを、５端子以上として、その追加分を信号取り出し用端子として使用してもよい。これらは、従来より電力供給用や電力供給と内部電動機の温度保護装置の信号取り出し用に使用していた密閉型端子が使用でき、製造上の品質面の確保は出来ており市場での信頼性についての実績もあり、確実に油面位置の検出ができ、圧縮機の信頼性を確保できる。   Further, a signal line 12 is connected to the oil level detection member, and the signal line is connected to a dedicated sealed terminal 11 provided on the upper shell of the housing 2. The detected signal is taken out through the sealed terminal. At this time, the sealed terminal 11 has three terminals in FIG. 1, but may be two terminals, four terminals, or the like as necessary. Further, the power supply sealed terminal 8 is usually three terminals. However, it is also possible to use five or more terminals and use the additional terminals as signal extraction terminals. These can use the sealed terminals that have been used for power supply and for the power supply and signal extraction of the temperature protection device of the internal motor, and can ensure the quality of manufacturing and are reliable in the market. The oil level position can be reliably detected and the reliability of the compressor can be secured.

また、図２は、上記第２の発明の信号線１８の詳細を示す。２０が信号導通部であり、２１が被覆部であり、例えば電動機巻き線に使われているような被覆銅線といった、その
周囲を絶縁性に優れ且つ耐冷媒性と耐熱性に優れた材質で被覆された線としている。 FIG. 2 shows details of the signal line 18 of the second invention. Reference numeral 20 is a signal conducting portion, 21 is a covering portion, and the periphery thereof is made of a material excellent in insulation, refrigerant resistance and heat resistance, such as a coated copper wire used in an electric motor winding. It is a covered wire.

また、上記信号線は、本発明の第３の発明の信号線でもよい。すなわち、図３に示すように、耐冷媒性と耐熱性に優れた材質の保護管、例えば四沸化エチレン樹脂といった材料を使った保護管１９に上記信号線１２を通して構成している。これは、上記信号線１８を全信号線に使用し、更に圧縮機構部や電動機やハウジングに接触の可能性のある部分に上記保護管１９を使用してもよい。これにより、組立時の取り扱いが容易になり、組立中の接触による傷等の発生が低減できる。また、運転中の電動機や圧縮機の振動による信号線と各部の擦れによる傷等の発生が低減でき、絶縁不良や接触不良による油面の誤検知を低減できる。   The signal line may be the signal line according to the third aspect of the present invention. That is, as shown in FIG. 3, the signal line 12 is formed through a protective tube 19 made of a material excellent in refrigerant resistance and heat resistance, for example, a material such as tetrafluoroethylene resin. In this case, the signal line 18 may be used for all signal lines, and the protective tube 19 may be used for a portion that may come into contact with the compression mechanism, the electric motor, or the housing. Thereby, handling at the time of assembly becomes easy, and generation | occurrence | production of the damage | wound etc. by the contact in assembly can be reduced. Further, it is possible to reduce the occurrence of scratches caused by rubbing between the signal line and each part due to vibration of the electric motor or compressor during operation, and it is possible to reduce erroneous detection of the oil level due to poor insulation or poor contact.

また、図４は上記のように構成された信号線を本発明の第４の発明の位置に配置した図である。又、図５は電動機４とハウジング２の上面図であり、隙間１３はガス又は油の流通路となっており、この隙間の１ケ所に信号線を通すよう構成する。これにより、従来の構造は変えずに容易に組み立てができる。   FIG. 4 is a diagram in which the signal lines configured as described above are arranged at the position of the fourth invention of the present invention. FIG. 5 is a top view of the electric motor 4 and the housing 2, and the gap 13 is a gas or oil flow passage, and the signal line is configured to pass through one place in the gap. As a result, the assembly can be easily performed without changing the conventional structure.

また、図６は本発明の第５の発明を示す図である。すなわち、本発明の第１、２、３の信号線を、電動機４の固定子６の一部に電動機４を境にした下部の圧縮機構部３の空間とハウジング２の上部空間を連通するよう穴１７を開け、上記信号線１２に通すよう構成したものである。図７は上部から見た上記固定子６と信号線１２を通す穴１７を示す。これにより、従来の固定子用鋼板の打ち抜き型を大幅に変えずに、信号線が固定子と一体となって固定されることとなり、組立時の信号線の扱いが容易になる。   FIG. 6 shows the fifth aspect of the present invention. That is, the first, second, and third signal lines of the present invention are connected to a part of the stator 6 of the electric motor 4 between the space of the lower compression mechanism portion 3 with the electric motor 4 as a boundary and the upper space of the housing 2. A hole 17 is formed so as to pass through the signal line 12. FIG. 7 shows a hole 17 through which the stator 6 and the signal line 12 pass as seen from above. Accordingly, the signal line is fixed integrally with the stator without significantly changing the conventional punching die of the steel plate for the stator, and the handling of the signal line at the time of assembly is facilitated.

また、図７は本発明の第６の発明を示す。本発明の第１の発明の油面検出部材と信号線と信号取り出し用密封端子を有する横型密閉型圧縮機である。ハウジング２電動機４固定子６圧縮機構部３油面検出部材１０信号線１２で構成されており、油面９を検出すると密閉端子１１からハウジング２の外部へ信号取り出す構成になっている。   FIG. 7 shows a sixth invention of the present invention. 1 is a horizontal hermetic compressor having an oil level detection member, a signal line, and a signal extraction sealing terminal according to a first aspect of the present invention; Housing 2 Electric motor 4 Stator 6 Compression mechanism 3 Oil level detection member 10 The signal line 12 is configured to extract a signal from the sealed terminal 11 to the outside of the housing 2 when the oil level 9 is detected.

以上のように、本発明にかかる密閉型圧縮機は、簡単な構造にしているために製造上も容易にでき、組立中の破損或いは運転中の振動等による破損も低減でき、油面の検出が確実におこなえるので、小型から大型の空調用、冷凍用、或いは給湯用密閉型圧縮機の油面の確認や制御に適用できる。   As described above, since the hermetic compressor according to the present invention has a simple structure, it can be easily manufactured, can reduce damage during assembly or vibration due to vibration during operation, and the like. Therefore, it can be applied to the confirmation and control of the oil level of a hermetic compressor for air conditioning, refrigeration, or hot water supply from small to large.
