Embodiment Construction

[0023] Hereinafter, the structure of the hermetic compressor provided by the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0024] Such as figure 1 As shown, the hermetic compressor provided in this embodiment is formed by a hermetic container 1 in appearance. One side of the airtight container 1 is connected with a suction conduit 2, which is used to guide the refrigerant flowing through the evaporator of the refrigeration cycle into the inside of the airtight container, and the other side of the airtight container 1 is connected with a discharge conduit 3, which is used to draw the refrigerant in the airtight container. The refrigerant discharged after being compressed inside the container 1 is guided to the condenser side of the refrigeration cycle.

[0025] And, the inside of the airtight container 1 is provided with a compression unit 20 for compressing the refrigerant and a drive unit 30 for provi...

Abstract

The invention provides a sealed compressor. The compressor comprises a piston, a cylinder having a compressing chamber formed inside and allowing the piston to perform linear reciprocating motion inside the compressing chamber. A fixing part extends along the periphery of the cylinder front. The compressor further comprises a cylinder cover fixed on the cylinder through the fixing part and sealing the compressing chamber, multiple fixing bolts for fixing the cylinder cover on the fixing part; multiple first bolt fixing holes equipped on the corners of the cylinder cover and applied for fixing the bolts; and multiple second bolt fixing holes equipped on the fixing part and aligned with the first bolt fixing holes for fixing the fixing bolts. In the fixing part, multiple grooves are equipped between the second bolt fixing holes and the compressing chamber. Each groove which is concentric to the compressing chamber is circular-arc shaped. The multiple grooves are equipped on the circumferential direction in a spaced way. Possible cylinder deformation phenomena are thus effectively prevented during a cylinder cover fixing process.

Description

technical field [0001] The present invention relates to a hermetic compressor, and more particularly to a hermetic compressor capable of effectively suppressing deformation of a cylinder that may occur during fixing of a cylinder head. Background technique [0002] Generally, a hermetic compressor refers to a device used to compress refrigerant in the refrigeration cycle of a refrigerator or air conditioner. [0003] The appearance of this type of hermetic compressor is formed by a hermetic container, and the interior of the hermetic container is provided with a compression unit for compressing the refrigerant and a driving unit for providing a driving force for compressing the refrigerant. [0004] Also, such a compression unit is often used in hermetic compressors, that is, a cylinder having a compression chamber formed by an internal space and a linearly reciprocating piston provided inside the compression chamber. [0005] A cylinder head is fixed to one end of the cyli...
