Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem in an accumulator for a hermetic compressor, that its reliability is impaired because the accumulator corrodes early by the accumulation of liquid generated by dew condensation and the like between an accumulator upper lid and a body shell. <P>SOLUTION: As the upper lid 2 constituting a container has a structure of overhanging the body shell 3, the liquid generated by dew condensation and the like does not accumulate between the upper lid 2 and the body shell 3, thus the corrosion of the accumulator can be prevented, and the accumulator of high reliability can be provided. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an accumulator used for a compressor used in refrigeration equipment such as air-conditioned air and a refrigerator.

  Conventionally, an accumulator for a hermetic compressor is hermetically sealed by a hermetic container constituted by an upper lid, a lower lid, and a shell, a refrigerant suction pipe that penetrates the center of the upper end of the hermetic container, and a lower end of the hermetic container. It is constituted by the partition plate having an outlet pipe erecting toward the inside of the container, a partition plate disposed between the refrigerant suction pipe and the outlet pipe, and a plurality of refrigerant circulation holes.

In the said structure, as shown in FIG. 2, the upper cover has the shape which entered the trunk | shell shell (for example, refer patent document 1).

  However, in the conventional method, the liquid generated by condensation or the like stays between the accumulator upper lid and the shell, and the corrosion of the accumulator is promoted, leading to a decrease in the reliability of the reliable compressor.

  The present invention solves the above-described conventional problems. By adopting a structure in which the upper cover of the accumulator is covered with the shell shell, liquid does not collect between the upper cover and the shell shell, thereby preventing corrosion and highly reliable compression. It aims at providing the accumulator for machines.

  In order to solve the above-described conventional problems, the present invention has a structure in which an accumulator upper lid is covered with a shell shell.

  As a result, liquid does not accumulate between the upper lid and the shell, and corrosion of the accumulator can be prevented.

  The accumulator for a compressor of the present invention can prevent corrosion without a liquid staying between the upper lid and the shell, and can provide a highly reliable compressor.

  The present invention relates to a sealed container composed of an upper lid, a lower lid, and a shell, a refrigerant suction pipe that penetrates the center of the upper end of the sealed container, and a lower end of the sealed container toward the inside of the sealed container. In an accumulator for a compressor having an upright outlet pipe, a partition plate disposed between the refrigerant suction pipe and the outlet pipe, and a plurality of refrigerant flow holes provided in the partition plate, an upper lid covers the trunk shell With the covering structure, the liquid generated by condensation or the like does not stay between the upper lid and the shell, and the accumulator can be prevented from corroding.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by embodiment described below.

(Embodiment 1)
In FIG. 1, the sealed container 1 is constituted by an upper lid 2, a body shell 3, and a lower lid 4. The hermetic container is characterized in that the upper lid 2 covers the trunk shell 3 and the lower lid 4 enters the trunk shell 3. Since the upper lid 2 covers the trunk shell 3, the liquid generated by condensation or the like does not stay between the upper lid 2 and the trunk shell 3 and can prevent corrosion of the accumulator. Further, by adopting a structure in which the lower lid 4 is inserted into the shell 3, liquid generated by condensation or the like does not stay between the lower lid 4 and the shell 3, and corrosion of the accumulator can be prevented. As described above, a highly reliable compressor can be provided by employing a structure in which liquid generated by condensation or the like does not stay.

  As described above, the accumulator for a multi-cylinder compressor according to the present invention can be applied to an accumulator of any hermetic electric compressor regardless of its size.
