Abstract

PURPOSE:To prevent the generation of a standing wave in between a base plate and a lower shell and reduce the generation of the noise of a compressor by forming said lower shell of an enclosed container into nearly a semispherical shape projecting out downward and fixing this enclosed container on the base plate of an installing body via a vibration isolating device. CONSTITUTION:An enclosed container consists of an upper shell 1, a cylindrical shell 2, and a semispherical lower shell 6 which is projected out downward, and a motor element 4 and a compressing element 5 are housed in a vertical arrangement in this enclosed container. And, the enclosed container is placed on the base plate 7 of an air compressor body via a rubber vibration isolator 10. Since the lower shell 6 of this compressor has a semispherical shape, no uniform space exists between said base plate 7 and the spherical lower shell 6. Accordingly, when operating the compressor, no standing wave is generated between the base plate 7 and the shell 6, being affected by the noise and vibration from the shell 6. As a result, noise generated from between the base plate 7 of the air compressor body and the semispherical lower shell 6 can be reduced.

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.

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.

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.

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.

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.

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.

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.
