Abstract
The present invention relates to a linear compressor. A discharge unit of the linear compressor according to an aspect of the present invention includes a discharge cover coupled with the frame. In addition, the discharge cover includes a cover flange portion and a chamber portion. At this time, the cover flange portion includes a flange main body having a main body penetration portion and a main body extension portion provided outward in a radial direction so as to face the main body penetration portion, and a flange coupling portion having a flange coupling hole into which a fastening member for coupling with the frame is inserted.
Claims20
A linear compressor comprising:
- a cylinder that defines a compression space configured to receive refrigerant;
- a frame that accommodates at least a portion of the cylinder;
- and
- a discharge unit that defines a discharge space configured to receive refrigerant discharged from the compression space, the discharge unit being configured to allow refrigerant discharged from the compression space to flow through the discharge space,
- wherein the discharge unit comprises a discharge cover coupled to the frame, the discharge cover comprising:
- a cover flange portion that faces a front surface of the frame in an axial direction of the cylinder, and
- a chamber portion that extends forward from the cover flange portion in a direction away from the front surface of the frame in the axial direction,
- wherein the cover flange portion comprises:
- a flange main body comprising a main body penetration portion that defines a circular opening and a main body extension portion that extends outward of the main body penetration portion in a radial direction of the cylinder, and
- a flange coupling portion that defines a flange fastening hole configured to receive a coupling member to couple the discharge cover to the frame, and
- wherein at least a portion of the flange coupling portion is positioned outward of the flange main body in the radial direction.
A linear compressor comprising:
- a cylinder that defines a compression space configured to receive refrigerant;
- a frame that accommodates at least a portion of the cylinder;
- and
- a discharge cover that is coupled to the frame and that defines a discharge space configured to receive refrigerant discharged from the compression space, the discharge cover being configured to allow refrigerant discharged from the compression space to flow through the discharge space,
- wherein the discharge cover comprises a flange main body that faces the frame and that has a circular outer appearance defining a flange outer diameter,
- wherein the frame comprises a discharge frame surface that contacts the discharging cover and that has a circular outer appearance defining a frame outer diameter, and
- wherein a ratio of the flange outer diameter to the frame outer diameter is in a range from 0.6 to 0.9.
