Abstract
The invention relates to the design of a capsule for a hermetically encapsulated small refrigerator. The damping of noise is an important requirement and to this end it is conventional that the motor-compressor unit mounted in the capsule is resiliently mounted relative thereto. The radiation of noise generated in the capsule is thwarted by arranging opposite wall sections in nonparallel relationships so that a sound wave striking a wall section is prevented from being reflected to a parallel wall section which would be conducive to amplification by continuing reflection.

A casing for hermetically encapsulated small refrigerators, comprising, a capsule having a lower vessel and an upper cover interconnected along a welded edge, said capsule having side walls inclined relative to each other so that almost any line drawn perpendicular to any one of said walls meets the opposite one of said walls at an angle different from 90.degree., the angle of incidence departing at least 5.degree. from 90.degree..
A casing for hermetically encapsulated small refrigerators, comprising, a capsule having a lower vessel and an upper cover interconnected along a welded edge, said capsule having side walls inclined relative to each other so that almost any line drawn perpendicular to any one of said side walls meets the opposite one one of said side walls at an angle different from 90.degree., the lower vessel side walls including opposite longitudinal walls and a pair of oppositely facing transverse walls having a first wall that is generally vertical and an opposite transverse second wall that extends generally vertically at an angle relative to said first wall.
