Abstract
A linear compressor is provided. The linear compressor may include a cylinder that defines a compression space, a piston having a plurality of suction holes through which a refrigerant is introduced into the compression space, and a muffler connected to the piston and through which the refrigerant supplied to the piston flows. The muffler may include a seat seated on one side of the piston, and a protrusion arranged inside the piston. The protrusion may include plurality of flow pipes that extends from the seat to an inside of the piston to guide the refrigerant to the plurality of suction holes and a resonator arranged at one side of the plurality of flow pipes and having a resonance space therein.
Claims20
A linear compressor, comprising:
- a cylinder that defines a compression space;
- a piston having a plurality of suction holes through which refrigerant is introduced into the compression space;
- and
- a muffler connected to the piston and through which the refrigerant supplied to the piston flows, the muffler including:
- a seat seated on one end of the piston;
- and
- a protrusion arranged at an inside of the piston, the protrusion including:
- a plurality of flow pipes that extends from the seat to the inside of the piston to guide the refrigerant to the plurality of suction holes;
- and
- a resonator arranged at radially inside of the plurality of flow pipes and having a resonance space therein.
A linear compressor, comprising:
- a shell that defines an outer appearance;
- a suction pipe provided on one end of the shell through which a refrigerant is suctioned to an inside of the shell;
- and
- a suction muffler provided to reduce noise generated by the refrigerant suctioned through the suction pipe, wherein the suction muffler includes:
- a first muffler having a resonance space therein;
- a second muffler coupled to one side of the first muffler;
- and
- a third muffler that accommodates the second muffler therein, and extends to a rear side of the first muffler, wherein the first muffler includes a refrigerant distributor located at a center of the first muffler and arranged at one end of the resonance space.
A linear compressor, comprising:
- a suction pipe into which refrigerant is introduced;
- and
- a muffler through which refrigerant introduced through the suction pipe passes, wherein the muffler includes:
- a plurality of flow pipes;
- a refrigerant distributor configured to distribute the refrigerant such that the refrigerant flows to the plurality of flow pipes;
- and
- a resonator arranged between the plurality of flow pipes to define a predetermined resonance space, wherein the plurality of flow pipes is arranged outside of the resonator around the resonator.
