が要求される場合が多くある。2. Description of the Related Art Compressors for refrigerators such as air conditioners and refrigerators are often required to be extremely low in height, that is, to be of horizontal type with a horizontal axis of rotation.
第３図は従来の横型の電動圧縮機の一例である。FIG. 3 shows an example of a conventional horizontal electric compressor.
密閉容器１０１の内部に設けた誘尋電動機の固定子１０
２の中心に回転子１０３を配設し、回転子１０３の回転
軸をほぼ水平にし、圧縮機構１０４の駆動軸１０５を回
転子１０３に結合する。Stator 10 of a dielectric motor provided inside a sealed container 101
A rotor 103 is disposed at the center of the compressor 2, the rotation axis of the rotor 103 is made substantially horizontal, and a drive shaft 105 of the compression mechanism 104 is coupled to the rotor 103.

吐出管１１０を曲って圧縮機の外に吐出される。After the refrigerant is sucked into the compression mechanism 104 from the suction port 106 and compressed, it is discharged from the airtight container 10 from the discharge port 107 of the compression mechanism.
stator 1 while cooling the motor.
The discharge pipe chamber 109 provided on the opposite side of the compression mechanism 104 with respect to the electric motor also bends through the compressor discharge pipe 110 and is discharged to the outside of the compressor through the passage 1108 on the outer periphery of the compressor.
密閉容器の下部には潤滑油１１１が封入されてる。匝翰
ｊ機の運転中は固定子の外周通路１０８の下方部分は潤
滑油１１１に満たされ、圧縮された冷媒は外周通路１０
８の上方部分を通過する。Lubricating oil 111 is sealed in the lower part of the sealed container. During operation of the Sokan J machine, the lower part of the outer circumferential passage 108 of the stator is filled with lubricating oil 111, and the compressed refrigerant flows into the outer circumferential passage 10.
Pass through the upper part of 8.
発明が解決しようとする問題点
ところが、上記従来の構成は、潤滑油１１１の油面が回

て、ａＥ縮機吐出管１１０から多ｉｌｉの潤滑油が流出
したり、回転子の動力損失が発生したりする。Problems to be Solved by the Invention However, in the conventional configuration described above, when the oil surface of the lubricating oil 111 comes into contact with the rotor 113, the rotor hits the oil surface of the lubricating oil and generates many oil droplets. This may cause the oil level to fluctuate, causing a large amount of lubricating oil to flow out from the aE compressor discharge pipe 110, or causing power loss to the rotor.

助長されたり、圧縮機構部に供給する４″Ｊ１滑油が不
足したりする。However, if the flow velocity of the refrigerant passing through the upper part of this outer peripheral passage is high, the passage resistance will cause the discharge pipe chamber 109 to
The internal pressure becomes lower than the pressure at the discharge port 107, and as a result, the oil level of the lubricating oil 111 in the motor part and the discharge pipe chamber 109 becomes high, and on the contrary, the pressure in the compression mechanism 104
The oil level of the lubricating oil in the vicinity of the compressor may drop, which may aggravate the occurrence of the above-mentioned problem or cause a shortage of 4"J1 lubricating oil supplied to the compression mechanism.

機構周辺の潤滑油１１１の油面が過度に下がったりする
問題があった。As mentioned above, the F114 uses a normal induction motor in which the rotor 103 is the center and the stator 102 is arranged around the outer periphery.
In the case of a compressor with a small diameter airtight container, the refrigerant output volume is particularly low. There is a problem in that the oil level of the lubricating oil 111 in the vicinity drops excessively.

``4.It will not only cause a slippage, but will also reduce the refrigerating capacity of the refrigerator.
更に、これらの間頌を解決しようとすれば圧縮機の外径
が犬になったりコスト、重量が増大することになった。Furthermore, if these problems were to be solved, the outer diameter of the compressor would increase, and the cost and weight would increase.
問題点を解決するだめの手段
上記問題点を解決する本発明の技術的手段に、電動機を
内側が固定子、外側が回転子の構成にし、圧席１機構の
吐出口から出た圧縮冷媒を回転子の外周付近に形成した

を経て圧縮機吐出室側に導くようにしたものである。Means for Solving the Problems The technical means of the present invention for solving the above problems is to configure the electric motor to have a stator on the inside and a rotor on the outside, and to use compressed refrigerant discharged from the discharge port of the pressure seat 1 mechanism. After passing through a centrifugal fan passage formed near the outer periphery of the rotor, the fan passes around the stator of the electric motor and is guided to the compressor discharge chamber side.
さらに、圧縮機構部の外周を延長して回転子側に吐出口
を開口させた吐出口室とその反対側の油溜室を仕切る隔

内側以降の圧力を油溜室に連通させる圧力連通孔を設け
ることである。Furthermore, the outer periphery of the compression mechanism section is extended to form a partition wall that partitions a discharge port chamber with a discharge port opened on the rotor side and an oil reservoir chamber on the opposite side, and an oil flow passage is provided in the lower part of the partition wall. A pressure communication hole is provided to communicate the pressure from the inside of the rotor to the oil reservoir chamber.
作 用 この基本の技術的手段による作用は次のようになる。For production The effect of this basic technical means is as follows.
すなわち、圧縮機構の吐出口室内の潤滑油などの液滴を
含む圧縮冷媒は回転子の遠心ファン通路で液滴が分離さ

却した後吐出管室を経て圧縮機吐出管に至る。In other words, the compressed refrigerant containing droplets such as lubricating oil in the discharge port chamber of the compression mechanism is separated into droplets by the rotor's centrifugal fan passage, and only the refrigerant gas enters the inside of the rotor to cool the stator. It reaches the compressor discharge pipe via the post-discharge pipe chamber.
回転子の内側にある液滴は遠心ファンの作用で圧縮機（
１゛４の方に戻される。The droplets inside the rotor are compressed by a centrifugal fan (
It will be returned to 1゛4.
さらに、圧力連通孔によって、油溜室の圧力が吐出口室
よりわずかに低く保つことができるので、潤滑油が油流
通路を通じて油溜室に確実に集められる。Furthermore, the pressure communication hole allows the pressure in the oil sump chamber to be kept slightly lower than that in the discharge outlet chamber, thus ensuring that lubricating oil is collected in the oil sump chamber through the oil flow passage.
