Description

本発明に係る密閉型圧縮機は、密閉容器の内部に圧縮機構部とそれを駆動する電動機部とを有し、冷媒回路に冷媒を循環させるための吐出管と吸入管とを備えた密閉型圧縮機において、密閉容器は、円筒状の下側容器と、これに嵌着し固定される有蓋円筒状の上側容器とを備え、上側容器の蓋部は、円弧の中心が密閉容器の内側にある球面と円弧の中心が密閉容器の外側にある球面とを組合せた円蓋状に形成されているものである。 A hermetic compressor according to the present invention includes a compression mechanism part and an electric motor part that drives the compression mechanism part inside a hermetic container, and is equipped with a discharge pipe and a suction pipe for circulating the refrigerant in the refrigerant circuit. in the compressor, the sealed container comprises a lower container of a circular cylindrical, and a lidded cylindrical upper container that is this was fitted and fixed, the cover portions of the upper container, the circular arc center of the sealed container in which the spherical and the center of the arc on the inside is formed in a circular lid-like a combination of a spherical surface outside the sealed container.

本発明の密閉型圧縮機によれば、密閉容器の上側容器の蓋部は、円弧の中心が密閉容器の内側にある球面と円弧の中心が密閉容器の外側にある球面とを組合せた円蓋状に形成されているので、上側容器の円蓋状の蓋部の強度を確保することができる。そのため、気密端子やその周辺に設置する付属品の設計、取り付けが容易となる。 According to the hermetic compressor of the present invention, the lid portion of the upper container of the sealed container, a circle center of the circle arc is spherical and the center of the arc on the inside of the sealed container combination of a spherical surface outside the sealed container Since it is formed in a lid shape, the strength of the lid-shaped lid portion of the upper container can be ensured. This facilitates the design and attachment of the hermetic terminal and accessories installed around it.
