Abstract
A reciprocating type compressor includes a crank shaft that is coupled to a rotor of a motor to transfer a rotational force, a piston that compresses a refrigerant while linearly moving within a cylinder of a compression portion, a connecting rod that connects the crank shaft to the piston to convert a rotational force of the crank shaft into a linear motion of the piston, and a cylinder boss integral body in which the cylinder and a boss that encloses the crank shaft are integrally formed at right angles to each other.
Claims20
A reciprocating type compressor, comprising:
- a cylinder boss integral body in which a cylinder and a boss are integrally formed at right angles to each other;
- a crank shaft that is coupled to a rotor of a motor to transfer a rotational force from the rotor to the crank shaft;
- a piston that compresses a refrigerant while linearly moving within the cylinder;
- and
- a connecting rod that connects the crank shaft to the piston to convert the rotational force of the crank shaft into a linear motion of the piston.
A reciprocating type compressor, comprising:
- a crank shaft that is coupled to a rotor of a motor to transfer a rotational force from the motor to the crank shaft;
- a piston that compresses a refrigerant while linearly moving within a cylinder;
- a connecting rod that connects the crank shaft to the piston to convert the rotational force of the crank shaft into a linear motion of the piston;
- and
- a cylinder boss integral body, the cylinder boss integral body comprising:
- the cylinder that provides a compression space at an interior thereof to allow the piston to compress a refrigerant while linearly moving;
- a boss that is connected to the cylinder in a direction perpendicular to the cylinder and includes a shaft insertion hole into which the crank shaft is inserted;
- and
- a right angle connecting frame that connects the cylinder and the boss so that an angle between an axis of the cylinder and an axis of the boss is a right angle, and wherein the reciprocating type compressor further comprises:
- a lower frame that includes a first mounting hole into which the boss is inserted;
- and
- an upper frame that is coupled to an upper portion of the lower frame, and includes a second mounting hole to which an upper end of the crank shaft is coupled in a penetrating manner at a location that faces the first mounting hole.
A reciprocating type compressor, comprising:
- a cylinder boss integral body including a cylinder that extends axially in a first direction and a boss that extends axially in a second direction perpendicular to the first direction;
- a crank shaft configured to be inserted into the boss, a first end of the crank shaft being connected to a stator of a motor;
- a piston configured to be inserted into the cylinder;
- and
- a connecting rod configured to connect the piston to the crankshaft and to convert a rotational force of the crank shaft into a linear motion of the piston, wherein the cylinder boss integral body further includes a connecting frame that maintains the cylinder and the boss perpendicular to each other.
