産業上の利用分野
木発明は、空調機等に用いられる縦形密閉回転式圧縮機
に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vertical hermetic rotary compressor used in air conditioners and the like.
従来の技術

図または、第3図のような構造になっていた。2. Description of the Related Art Conventional hermetic high-pressure rotary compressors of this type are disclosed in Japanese Utility Model Application Publication No. 56-124281, for example.
The structure was as shown in Figure 3.

点をもっていた。Problems to be Solved by the Invention However, with the lower shell 3 having such a shape, when the air conditioner or the like is damaged, the shape of the lower shell facing the substrate 7 is flat or nearly flat; The distance between the legs 8 and 7 is uniform, and standing waves are likely to occur, and the space 9 composed of the legs 8, the lower shell 3, and the substrate 7 resonates with the sound coming from the lower shell 3, It had the disadvantage of generating a lot of noise.
そこで、木発明は基板7と下部シェルとの間での定在波
発生を防ぎ、圧縮様から発生する吸音を低減するもので
ある。Therefore, the wooden invention prevents the generation of standing waves between the substrate 7 and the lower shell, and reduces sound absorption generated from compression.
問題壱、を・π決するための手段
上記問題点を解決する木発明の技術的な手段は、密閉容
器を形成する下部シェルを従来の賂平坦な形状から、下
方向に突出する略半球形状にするものである。The technical means of the invention to solve the above problems is to change the lower shell forming the airtight container from the conventional flat shape to a substantially hemispherical shape that protrudes downward. It is something to do.
作用 この技術的手段による作用は次のようになる。action The effect of this technical means is as follows.

れる。In other words, when a sealed high-pressure rotary compressor, in which the motor element and the compressor element are housed in a sealed container with a hemispherical lower shell arranged in a northward direction, is installed in the main body of an air conditioner, etc. Since the space between the base plate of the main body and the hemispherical lower shell is not sandwiched by a uniform distance, no standing waves are generated even when the compressor is in operation. Furthermore, by making the shell spherical, rigidity is increased and vibration is also reduced for the same excitation force, both of which reduce noise.
実施例
以下、本発明の一実施例の構成について、添付図面にも
とづいて説明する。Embodiment Hereinafter, the configuration of an embodiment of the present invention will be explained based on the accompanying drawings.

より構成され、この密閉容器内に、電動機要素4と圧縮
機要素5がそれぞれ上下方向の配列となるように収納さ
れている。そして密閉容器は、防振ゴム10を介して基
板7上に配置されている。In FIG. 1, the sealed container is composed of three parts: an upper shell 1, a cylindrical shell 2, and a hemispherical lower shell 6 projecting downward. Inside this sealed container, a motor element 4 and a compressor element 5 are installed. They are stored in a vertical arrangement. The airtight container is placed on the substrate 7 via the vibration-proof rubber 10.
次に、上記の密閉高圧形回転式圧縮機をエアコン本体の
基板7上に搭載し、運転させたときの作用を説明する。Next, the operation of the hermetically sealed high-pressure rotary compressor mounted on the board 7 of the air conditioner main body and operated will be described.
この圧縮機の下部シェルは半球形状であるため、エアコ

離の空間がない。そのため、圧縮機運転中に、半球形下
部シェル6からの騒音・振動が影響して、エアコン本体
の基板7と半球形下部シェル6との間に定在波を生じさ
せない。Since the lower shell of this compressor has a hemispherical shape, there is no space with a uniform distance between the base plate 7 of the air conditioner body and the hemispherical lower shell 6. Therefore, during the operation of the compressor, noise and vibration from the hemispherical lower shell 6 are not affected and standing waves are not generated between the substrate 7 of the air conditioner main body and the hemispherical lower shell 6.
この結果、エアコン本体の基板7と半球形下部シェル6
との間から発生する牙音の低減が行なえる。As a result, the substrate 7 of the air conditioner body and the hemispherical lower shell 6
It is possible to reduce the noise generated between the two.
また、本実施例においては、下部シェル6を半球形状に

形の下部シェル3と比べて、剛性が増大する。そのため
、半球形下部シェル6の板厚を薄くすることができ、コ
ストダウンを図ることもできる。Furthermore, in this embodiment, by forming the lower shell 6 into a hemispherical shape, the rigidity is increased compared to the conventional lower shell 3 which is flat or slightly curved. Therefore, the thickness of the hemispherical lower shell 6 can be reduced, and costs can be reduced.
発明の効果
以上のように本発明は、密閉容器を形成する下部シェル

シェルの剛性も増し、加振力に対する振動も抑制でき、
一層の騒音低減がはかれる効果を奏する。Effects of the Invention As described above, the present invention provides a hemispherical shape for the lower shell forming the airtight container, so that when mounted on the board of a refrigeration equipment, standing waves are generated between the board and the lower shell. This reduces noise, increases the rigidity of the lower shell, and suppresses vibrations caused by excitation forces.
This has the effect of further reducing noise.
