Problems solved by technology
Therefore, more refrigerant is recovered than oil, further reducing the cooling capacity of compressors and refrigeration cycle equipment
[0007] In addition, since the oil that has been separated by the oil separator and then recovered is mixed with the sucked refrigerant, the oil is discharged together with the refrigerant via the compression unit, thereby leaving an insufficient amount of oil in the inner space of the casing, resulting in Compressor reliability further deteriorates

Embodiment Construction
[0030] A compressor and a refrigeration cycle apparatus having the compressor according to the present invention will now be described in detail with reference to the accompanying drawings. Although the invention has been described with reference to a hermetic scroll compressor, the invention is not limited to scroll compressors, but is equally applicable to other so-called compressors having a motor and a compression unit within the same casing. Hermetic compressors, such as rotary compressors.
[0031] figure 1 is a perspective view showing the exterior of a scroll compressor as one example of the compressor according to the present invention: figure 2 is a longitudinal sectional view showing the interior of the compressor.
[0032] Such as figure 1 and figure 2 As shown, the scroll compressor 1 according to the present invention may include: a compressor casing (hereinafter referred to as "casing") 10, which has a closed internal space; a motor 20, which is located in...

A hermetic compressor and a refrigeration cycle device having the same are provided. An oil separator is installed either outside or inside of a casing to separate oil from a discharged refrigerant and an oil pump driven by a driving force of a motor is used to recollect the oil separated in the oil separator, whereby the separation between oil and refrigerant can effectively be performed and also a fabricating cost can be reduced. Also, an introduction of the separated refrigerant back into the compressor can be prevented so as to improve a cooling capability of the refrigeration cycle device. In addition, the oil pump is driven by the driving force of the motor, resulting in a simple configuration of the compressor and reduction of a fabricating cost of the compressor.
Description
technical field [0001] The present invention relates to a compressor and refrigeration cycle equipment having such a compressor, and more particularly to an oil recovery device for a compressor capable of separating oil from refrigerant discharged from a compression unit of a compressor and recovering the oil . Background technique [0002] A compressor is a device that converts kinetic energy into compression energy of a compressed fluid. A hermetic compressor is configured such that a motor for generating a driving force and a compression unit for compressing a fluid by receiving the driving force from the motor are installed in an inner space of a hermetic container. [0003] When a hermetic compressor is provided as a component in a refrigerant compression type refrigeration cycle apparatus, a certain amount of oil is stored in the hermetic compressor to cool a motor of the compressor or to lubricate and seal the compression unit. However, when the compressor is driven...
