Abstract
Description
本発明は空気調和機の室外機等に設けられる圧縮機に関するものである。 The present invention relates to a compressor provided in an outdoor unit or the like of an air conditioner.
一般に空気調和機や冷凍機等に用いられる圧縮機は、図３に示すように、密閉容器１内に回転子２と固定子３からなる電動機部と、この電動機部（回転子２）と連結される圧縮機構部４と、密閉容器１の底部にオイルを溜めるオイル溜まり５を備えている。また、回転子２は複数枚の積層鉄板（電磁鋼板）が積層されると共に、回転子２の上下方向（回転子２の回転軸方向）に亘って磁石を配置して、積層鉄板を（空洞化していない）かしめピン６によって一体化している。 As shown in FIG. 3, a compressor generally used in an air conditioner, a refrigerator, or the like is connected to an electric motor unit including a rotor 2 and a stator 3 in an airtight container 1 and the electric motor unit (rotor 2). And an oil reservoir 5 for accumulating oil at the bottom of the sealed container 1. The rotor 2 is formed by laminating a plurality of laminated iron plates (electromagnetic steel plates) and arranging magnets in the up and down direction of the rotor 2 (rotational axis direction of the rotor 2). They are integrated by caulking pins 6.
このような圧縮機では、冷媒とオイルとの分離が密閉容器１内で十分行われないと、外部回路（図示せず）にオイルが含まれた冷媒が流出し、これによって冷却効率が低下すると共に、密閉容器１内の底部のオイルが不足して、圧縮機構部４における作動が円滑に行えなくなるおそれがある。 In such a compressor, if the refrigerant and the oil are not sufficiently separated in the sealed container 1, the refrigerant containing the oil flows out to the external circuit (not shown), thereby reducing the cooling efficiency. At the same time, there is a risk that the oil in the bottom of the sealed container 1 is insufficient and the operation of the compression mechanism 4 cannot be performed smoothly.
一般的な圧縮機には、回転子２の内部に垂直に冷媒通路７を設けており、圧縮機構部４から吐出された冷媒は、回転子２の下部空間から冷媒通路７を経由し密閉容器１の上部空間に流れ、圧縮機から外部回路に吐出される。（例えば、特許文献１参照） In a general compressor, a refrigerant passage 7 is provided vertically inside the rotor 2, and the refrigerant discharged from the compression mechanism section 4 is sealed from the lower space of the rotor 2 via the refrigerant passage 7. 1 flows into the upper space of 1 and is discharged from the compressor to an external circuit. (For example, see Patent Document 1)
前記従来の構成では、モ−タ効率を向上するため回転子の内部に配置されている磁石位置によっては、冷媒通路を構成するためのスペ−スがなく、適切な冷媒通路を構成できないため、冷媒の流速が速くなり、外部回路へのオイル吐出が多くなるという課題を有している。 In the conventional configuration, depending on the position of the magnet disposed inside the rotor to improve motor efficiency, there is no space for configuring the refrigerant passage, and an appropriate refrigerant passage cannot be configured. There is a problem that the flow rate of the refrigerant is increased and oil discharge to the external circuit is increased.
本発明は、前記従来の課題を解決するもので、外部回路への圧縮機のオイル吐出の低減を図ることを目的とする。 The present invention solves the above-described conventional problems, and an object thereof is to reduce oil discharge of a compressor to an external circuit.
前記従来の課題を解決するために、本発明の圧縮機は、密閉容器内に回転子および固定子からなる電動機部と、この電動機部と連結される圧縮機構部と、密閉容器底部にオイルを溜めるオイル溜まりを備え、前記回転子を構成する積層鉄板を固定するかしめピンを空洞化することにより、その空洞化した部分を冷媒が通過する冷媒通路とした。これにより、モータ効率を向上し、回転子の内部に配置された磁石位置に関係なく冷媒通路を設けることができ、オイル吐出を低減することができる。 In order to solve the above-described conventional problems, a compressor according to the present invention includes an electric motor unit including a rotor and a stator in a hermetic container, a compression mechanism unit connected to the motor unit, and oil at the bottom of the hermetic container. An oil reservoir is provided, and a caulking pin for fixing the laminated iron plate constituting the rotor is hollowed to provide a refrigerant passage through which the refrigerant passes. Thereby, motor efficiency can be improved, a refrigerant path can be provided irrespective of the position of the magnet disposed inside the rotor, and oil discharge can be reduced.
以上のように本発明によれば、外部回路への圧縮機のオイル吐出を低減することができる。 As described above, according to the present invention, oil discharge from the compressor to the external circuit can be reduced.
以下、本発明の実施の形態について図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
（実施の形態１）
図１は、本発明の実施の形態１における圧縮機の概略図を示すものである。また図２は本発明の実施の形態１における回転子の概略図を示すものである。
(Embodiment 1)
FIG. 1 shows a schematic diagram of a compressor according to Embodiment 1 of the present invention. FIG. 2 shows a schematic diagram of the rotor according to the first embodiment of the present invention.
図１において、密閉容器１内には、回転子２と固定子３からなる電動機部と、その下側に圧縮機構部４、オイル溜まり５が備えられている。図２において、回転子２には回転子２を構成する積層鉄板（電磁鋼板）を固定するための空洞化したかしめピン８が設けられている。これらの空洞化したかしめピン８は、回転子２に設けられた磁石１０とは異なる領域に配される。 In FIG. 1, an airtight container 1 is provided with an electric motor part including a rotor 2 and a stator 3, and a compression mechanism part 4 and an oil reservoir 5 below the electric motor part. In FIG. 2, the rotor 2 is provided with a caulking pin 8 that is hollowed to fix a laminated iron plate (magnetic steel plate) that constitutes the rotor 2. These caulked caulking pins 8 are arranged in a region different from the magnet 10 provided in the rotor 2.
以上のように構成された圧縮機について、以下その動作、作用を説明する。 About the compressor comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
本実施の形態の回転子２の空洞化したかしめピン８は、中が空洞になっており、回転子２の内部に配置された磁石１０の位置に関係なく冷媒通路９を形成し、またモ−タ効率を向上することができる。冷媒通路９を形成することにより、冷媒ガスが吐出される通路を拡大することができ、冷媒ガスの流速を遅くすることにより外部回路への圧縮機のオイル吐出を低減することができる。 The caulking pin 8 that has been hollowed out in the rotor 2 of the present embodiment has a hollow inside, forms a refrigerant passage 9 regardless of the position of the magnet 10 disposed inside the rotor 2, and -Data efficiency can be improved. By forming the refrigerant passage 9, the passage through which the refrigerant gas is discharged can be enlarged, and by reducing the flow rate of the refrigerant gas, the oil discharge of the compressor to the external circuit can be reduced.
以上のように、本発明にかかる圧縮機は、圧縮機のオイル吐出の低減が可能となるので、ロータリ式の圧縮機以外にスクロール式の圧縮機の用途にも適用できる。 As described above, the compressor according to the present invention can reduce the oil discharge of the compressor, and thus can be applied to the use of a scroll compressor in addition to the rotary compressor.
