Problems solved by technology

[0007] However, in such a conventional hermetic compressor, due to the insertion of the cylindrical part, there is inevitably a large gap between the stator generating the magnetic flux and the electrical steel sheet, which leads to a decrease in the output efficiency of the motor
[0008] In addition, the need for such a separate cylindrical part results in overall operational complexity and increased production costs

Embodiment Construction

[0021] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] refer to figure 1 , shows the overall structure of the compressor according to the present invention in a side sectional view.

[0023] Such as figure 1 As shown in , the hermetic compressor of the present invention includes: a compression unit 20 for compressing refrigerant, which is installed in a hermetic casing 10 defining a closed internal space; and a driving unit 30 for driving the compression unit 20 .

[0024] The compression unit 20 includes: a cylinder 21 defining a compression chamber 21 a therein; and a piston 22 linearly reciprocating in the compression chamber 21 a to compress refrigerant. A cylinder head 23 is connected to one side of the cylinder body 21, and the cylinder head 23 defines a discharge chamber 23b and a suction chamber 23a communicating with the outside. A valve device 24 is provided between the cylinder ...

Abstract

The invention relates to an enclosed compressor with a rotor which comprises a cascade body consisting of a plurality of electrical strips overlapped vertically, a plurality of magnets arranged along the periphery of the cascade body and a pair of support chips arranged at the top and the bottom of the cascade body for supporting them. The support chip forms a plurality of fixed convex parts which are inserted into a plurality of magnets to prevent the radial separation of the magnet.

Description

[0001] This application claims priority from Korean Patent Application No. 2004-32323 filed with the Korean Intellectual Property Office on May 7, 2004, the disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a hermetic compressor, and more particularly, to a hermetic compressor including a rotor that rotates by electromagnetically interacting with a stator that generates a magnetic field. technical background [0003] Generally speaking, a hermetic compressor is a device designed to draw refrigerant into its closed internal space and discharge the refrigerant in a compressed state. Such a hermetic compressor includes a compression unit for compressing refrigerant, and a driving unit for driving the compression unit. [0004] The compression unit is located within a closed housing defining a closed interior space. Such a compression unit comprises a cylinder defining a compression chamber, and a piston performin...
