Abstract
A cylinder block for a compressor includes: a shaft support configured to support a rotary shaft of an outer rotor type motor; a first support that is arranged radially outward of the shaft support and that extends along a circumferential direction about a center of the shaft support; a second support that is arranged radially outward of the first support and that extends along the circumferential direction about the center of the shaft support; a third support that connects the first support to the second support; a cylinder portion that defines a cylindrical inner space at a position radially away from the center of the shaft support; and a noise chamber defined at at least one side of the cylinder portion.
Claims19
A cylinder block for a compressor, the compressor including an outer rotor type motor and a rotary shaft coupled to the outer rotor type motor, the cylinder block comprising:
- a shaft support configured to support the rotary shaft;
- a first support that is arranged radially outward of the shaft support and that extends along a circumferential direction about a center of the shaft support;
- a second support that is arranged radially outward of the first support and that extends along the circumferential direction about the center of the shaft support;
- a third support that connects the first support to the second support;
- a cylinder portion that defines a cylindrical inner space at a position radially away from the center of the shaft support;
- and
- a noise chamber defined at at least one side of the cylinder portion,
- wherein the cylinder block defines a first hole between the shaft support and the first support, the first hole extending along the circumferential direction.
A compressor comprising:
- a casing that defines a sealed inside space therein;
- a cylinder block located in the sealed inside space;
- a motor disposed in the sealed inside space at a position vertically below the cylinder block, the motor being an outer rotor type motor;
- a rotary shaft coupled to the cylinder block, the rotary shaft comprising an eccentric portion that is disposed at a position offset from a center of the rotary shaft and that is configured to be rotated by a rotational force of the motor;
- and
- a piston connected to the rotary shaft and configured to reciprocate within the cylinder block based on rotation of the eccentric portion,
- wherein the cylinder block comprises:
- a shaft support coupled to the rotary shaft and configured to support the rotary shaft,
- a first support that is arranged radially outward of the shaft support and that extends along a circumferential direction about a center of the shaft support,
- a second support that is arranged radially outward of the first support and that extends along the circumferential direction about the center of the shaft support, the second support surrounding at least a portion of an outer rotor of the motor,
- a third support that connects the first support to the second support,
- a cylinder portion that defines a cylindrical inner space configured to receive the piston, and
- a noise chamber defined at at least one side of the cylinder portion.
