Description

本考案は、ロータリー式コンプレッサに関するもので、高低圧を確実に隔離するロータリー式コンプレッサを提供する。   The present invention relates to a rotary compressor, and provides a rotary compressor that reliably isolates high and low pressures.

一般に圧縮冷媒を用い、その回路内で循環する電動コンプレッサは、基本的に直流モーターで動かして連結した圧縮システムで動作し、更に冷媒を圧縮して循環動作效果を達成する。内部コンプレッサシステムの違いがあるが、現在見られるのは、ロータリー式コンプレッサ(rotary compressor)、スクロール式コンプレッサ(scroll compressor)及びスクリュー式コンプレッサ(screw compressor)等のモデルを含む。 In general, an electric compressor that uses a compressed refrigerant and circulates in the circuit is basically operated by a compression system connected by a direct current motor and further compresses the refrigerant to achieve a circulation operation effect. Although there are differences in internal compressor systems, currently seen include models such as rotary compressors, scroll compressors and screw compressors.

上記スクロール式コンプレッサは、加工が相対的に困難なことから高価であるという問題がある。またロータリー式コンプレッサとスクリュー式コンプレッサは、どちらも圧縮室の容積を変えることに拠って、圧縮過程を完成するが、ロータリー式コンプレッサは更に簡潔な圧縮方式を採用することから、スクリュー式コンプレッサが軸方向へ受ける力の偏移、容積の余り、様々の内部洩漏等の根絶できない問題を上手に避け、設備の信頼性と効率を同時に大幅に高め、高い市場占有率を獲得している。 The scroll compressor has a problem that it is expensive because it is relatively difficult to process. Both the rotary compressor and screw compressor complete the compression process by changing the volume of the compression chamber, but the rotary compressor adopts a simpler compression method, so the screw compressor is the shaft. It successfully avoids problems that cannot be eradicated, such as deviations in the force applied to the direction, excess volume, and various internal leaks, greatly improving the reliability and efficiency of the equipment at the same time, and gaining a high market share.

原則的に、ロータリー式コンプレッサは、偏心軸をモーター回転子の中心に設置する。図１に示すとおり、ロータリー式コンプレッサ１０は、筐体１１の内部にモーター(回転子１２１及び固定子１２２を含む)、偏心軸１３及びシリンダー１４を設置する。偏心軸１３はモーター回転子１２１の回転に沿って、シリンダー１４内で回転した時、シリンダー壁と共に系列体積が異なる圧縮室(第一室１５と第二室１６を含む)を形成し、更に冷媒を圧縮する目的を達成する。 In principle, rotary compressors have an eccentric shaft in the center of the motor rotor. As shown in FIG. 1, the rotary compressor 10 is provided with a motor (including a rotor 121 and a stator 122), an eccentric shaft 13, and a cylinder 14 inside a housing 11. When the eccentric shaft 13 rotates in the cylinder 14 along with the rotation of the motor rotor 121, it forms a compression chamber (including the first chamber 15 and the second chamber 16) having a different series volume together with the cylinder wall. Achieve the purpose of compressing.

上述の公知ロータリー式コンプレッサにおいて、該シリンダー１４と筐体１１間は、溶接方式だけで固定することから、該第一室１５と第二室１６の間は密封部品がなく仕切っている。更にロータリー式コンプレッサの筐体が傾斜した場合、該第二室内の冷凍機油は該第一室へ流れ、且つロータリー式コンプレッサの筐体が正常な使用位置に復帰した時、該第一室へ流れていた冷媒は、即座に第二室へ戻ることができず、コンプレッサ全体の実際の運転機能に影響が表れ、特にコンプレッサの効率が落ちる。更に、シリンダー１４と筐体１１間は、溶接方式で固定した時、シリンダー１４及び筐体１１は溶接箇所の金属を溶かすため、１０００℃を超えて溶接できる。溶接時、高すぎる温度は、シリンダー１４の熱変形を引き起こし、シリンダー１４の内壁のミクロン級の精度への影響が大きく、更にはシリンダーの漏れ、もしくは詰まり等の問題を起こす。特に体積が小さいロータリー式コンプレッサは、上述の熱変形の問題を完全に防ぐことはできない。 In the above-described known rotary compressor, the cylinder 14 and the housing 11 are fixed only by a welding method, so that the first chamber 15 and the second chamber 16 are partitioned without any sealing parts. Furthermore, when the rotary compressor housing is tilted, the refrigeration oil in the second chamber flows into the first chamber, and when the rotary compressor housing returns to the normal use position, it flows into the first chamber. The refrigerant that has been stored cannot immediately return to the second chamber, affecting the actual operation function of the entire compressor, and in particular, reducing the efficiency of the compressor. Furthermore, when the space between the cylinder 14 and the housing 11 is fixed by a welding method, the cylinder 14 and the housing 11 can be welded at a temperature exceeding 1000 ° C. because the metal at the welding location is melted. At the time of welding, a temperature that is too high causes thermal deformation of the cylinder 14, greatly affecting the accuracy of the inner wall of the cylinder 14 on the micron level, and causes problems such as cylinder leakage or clogging. In particular, a rotary compressor having a small volume cannot completely prevent the above-described problem of thermal deformation.

解決しようとする問題点は、高圧室及び低圧室の高低圧を確実に隔離できないことから、全体の運転機能に実際の影響が表れ、特にコンプレッサの効率が落ちる点である。 The problem to be solved is that the high and low pressure chambers cannot be reliably isolated from the high and low pressures, so that the actual operating function is affected and particularly the efficiency of the compressor is reduced.

本考案は、筐体の内部にモーター、偏心軸及びシリンダーを設置し，該モーターには回転子及び固定子が設置される。該偏心軸は、回転子の回転よってシリンダー内で回転し，該シリンダーは筐体を高圧室及び低圧室に区分する。該高圧室は該モーター及びシリンダーの間に位置し，該低圧室は該シリンダー下方に位置する。該シリンダーと該筐体の間に隔離部品を設置し，該高圧室及び低圧室を隔離するのに用い，該隔離部品は少なくとも一つの回流孔を備え，該回流孔は該隔離部品を貫通し、該高圧室及び低圧室間で連通する。該隔離部品によって確実に高低圧を隔離することを最も主要な特徴とする。   In the present invention, a motor, an eccentric shaft, and a cylinder are installed in a housing, and a rotor and a stator are installed in the motor. The eccentric shaft rotates in the cylinder by the rotation of the rotor, and the cylinder divides the housing into a high pressure chamber and a low pressure chamber. The high pressure chamber is located between the motor and the cylinder, and the low pressure chamber is located below the cylinder. An isolation component is installed between the cylinder and the housing and used to isolate the high pressure chamber and the low pressure chamber. The isolation component has at least one circulation hole, and the circulation hole penetrates the isolation component. The high pressure chamber and the low pressure chamber communicate with each other. The most important feature is that the high and low pressures are reliably isolated by the isolation parts.

本考案のロータリー式コンプレッサは、高圧室及び低圧室間の高低圧を確実に隔離するという利点がある。   The rotary compressor of the present invention has an advantage of reliably isolating high and low pressures between the high pressure chamber and the low pressure chamber.

In the embodiment shown in the figure, the isolation part 28 is a convex edge 281, and the convex edge 281 extends integrally from the casing 21 and protrudes from the inner wall of the casing 21 to form an annular structure. . The convex edge 281 is positioned above the cylinder portion 243, and the free end of the convex edge 281 is in pressure contact with the upper fixing base 241 so as to securely separate the high pressure chamber 26 and the low pressure chamber 27. The isolation component 28 includes at least one circulation hole 282, and the circulation hole 282 passes through the isolation component 28 and communicates between the high pressure chamber 26 and the low pressure chamber 27.
