Problems solved by technology

However, a suction loss may occur due to an increase in the specific volume in the suction pressure chamber due to an increase in the temperature of the suction refrigerant in contact with the drive motor
[0006] In addition, in the low-pressure type, the suction refrigerant that does not come into contact with the drive motor also comes into contact with the high-low pressure separation plate, or is heated by radiant heat, so the specific volume will further increase, which may aggravate the suction loss

Embodiment Construction

[0047] Next, according to an embodiment shown in the drawings, the scroll compressor of this embodiment will be described in detail.

[0048] figure 1 It is a longitudinal sectional view showing the inside of the capacity variable scroll compressor of this embodiment, figure 2 Yes figure 1 A cut-away perspective view of the interior of a scroll compressor, image 3 is in figure 2 A perspective view showing the assembly of the compression section in the scroll compressor.

[0049] refer to figure 1 and figure 2 , in the scroll compressor of this embodiment, a driving motor 120 is provided on the lower half of the housing 110, and a main frame 130, an orbiting scroll 140, and a non-orbiting scroll are arranged in sequence on the upper side of the driving motor 120. The turntable 150 and the back pressure chamber assembly 160 . Generally, the driving motor 120 constitutes an electric part, and the main frame 130, the orbiting scroll 140, the non-orbiting scroll 150, and...

Abstract

A scroll compressor may include a casing having a low pressure portion and a high pressure portion, a suction pipe that communicates with the low pressure portion and a discharge pipe that communicates with the high pressure portion, a drive motor installed inside of the low pressure portion, an orbiting scroll coupled to the drive motor to perform an orbiting motion, a non-orbiting scroll engaged with the orbiting scroll to form a compression chamber, and a refrigerant guide provided on the non-orbiting scroll to guide a refrigerant suctioned into the low pressure portion to be suctioned into the compression chamber, whereby an increase in specific volume of refrigerant suctioned into the compression chamber may be suppressed, and thus, an amount of refrigerant suctioned into the compression chamber may increase, thereby improving efficiency of the compressor.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular, to a suction flow path. Background technique [0002] In a scroll compressor, an orbiting scroll and a non-orbiting scroll are meshed together to form two pairs of compression chambers while the orbiting scroll orbits relative to the non-orbiting scroll. [0003] The compression chamber is composed of a suction pressure chamber formed on the periphery, an intermediate pressure chamber continuously formed in which the volume of the suction pressure chamber gradually decreases toward the center, and a discharge pressure chamber connected to the center side of the intermediate pressure chamber. Usually, the suction pressure chamber is formed penetrating the side surface of the non-orbiting scroll, the intermediate pressure chamber is sealed, and the discharge pressure chamber is formed penetrating the end plate portion of the non-orbiting scroll. [0004] On the other hand, the scroll c...
