Abstract

PURPOSE:To suppress the vibration of a discharge pipe and reduce the vibration of a sealed container by fixing the discharge pipe communicates to a part of the sealed container through the compression part of a compression element and a discharge line onto the sealed container through an indirect member. CONSTITUTION:A motor 2 and a compression element 3 are housed in a sealed container 1, and a compression part 4 which constitutes the compression element 3 communicates to a discharge pipe 6 through a discharge line 5. In this case, an indirect member 7 is fitted in a penetration part where the discharge pipe 6 penetrates through the sealed container 1, and the discharge pipe 6 is supported onto the sealed container 1 through the indirect member 7. Therefore, the vibration of the discharge pipe 6 which is transmitted from the discharge line 5 is attenuated by the indirect member 7, and the vibration of the sealed container 1 is suppressed, and noise can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hermetic reciprocating compressor used in refrigeration equipment such as refrigerators and air conditioners.

BACKGROUND OF THE INVENTION In recent years, hermetic reciprocating compressors have become smaller, more space-saving, and less noisy.

An example of a conventional hermetic reciprocating compressor will be described below with reference to the drawings.

3 and 4 show a closed type reciprocating compressor disclosed in Japanese Utility Model Application No. 57-83288, in which 1 is a closed container, 2 is a motor, 3 is a compression element, and 1 is a closed container 1. It is stored inside. 4 is a compression section constituting the compression element 3; 6;
6 is a discharge line, and 6 is a discharge pipe fixed to the closed container 1, which is connected to the compression section 4 by the day 7 charge line 6.

In the above configuration, the compression element 3 driven by the motor 2 is equipped with a refrigerant gas external cooling circuit (not shown).
The gas is guided from the compressor, compressed by the compressor 4, and discharged to the discharge pipe 6 via the discharge line 6.

Problems to be Solved by the Invention However, in the above configuration, vibrations generated in the compression section 4 are transmitted through the discharge line 6, causing the discharge pipe 6 to vibrate. Since the discharge pipe 6 is directly fixed to the closed container 1, the vibration of the discharge pipe 6 is directly transmitted to the closed container 1, causing the closed container 1 to vibrate and increase noise. .

In view of the above problems, the present invention provides a hermetic reciprocating compressor with low noise.

Means for Solving the Problems In order to solve the above problems, the present invention is provided with a configuration in which a discharge pipe is fixed to a closed container via an indirect member.

Function: With the above-described configuration, the vibration of the discharge pipe is attenuated by the indirect member while being transmitted to the closed container.

EXAMPLE Hereinafter, a hermetic reciprocating compressor according to an example of the present invention will be described with reference to the drawings. Note that the same parts as in the conventional example are indicated by the same reference numerals, and parts with the same structure and operation are omitted.

In FIGS. 1 and 2, 1 is a closed container, 6 is a discharge pipe, and 7 is an indirect member interposed between the closed container 1 and the discharge pipe 6, which connects the closed container 1 and the discharge pipe 6. are doing.

In the hermetic reciprocating compressor configured as above,
The vibrations generated in the compression section 4 are transmitted through the discharge line 6 and cause the discharge pipe 6 to vibrate. The vibration of the discharge pipe 6 is
It is transmitted to the indirect member 7, υ, and then transmitted to the closed container 1. During this time, the vibrations are greatly attenuated by the indirect member 7, so that the vibrations transmitted to the closed container 1 are reduced. Therefore, vibrations transmitted to the closed container 1 are reduced.

Therefore, since the trembling of the closed container 1 is suppressed, noise can be reduced.

Effects of the Invention As described above, in the present invention, by fixing the discharge pipe to the closed container via the indirect member, vibrations of the discharge pipe transmitted from the discharge line are attenuated by the indirect member while being transmitted to the closed container. In particular, it is possible to suppress the vibration of a closed container and reduce the noise level.
