Problems solved by technology

The electric motor is sized to compensate for the load at start, but must be operated at very low capacity during continued operation after start
Therefore, motors sized according to starting conditions result in increased cost and reduced efficiency

Embodiment Construction

[0031] The hermetic compressor 1 comprises: a housing 2, in which the elements are carried; an oil sump 3, which forms the lower part of the housing 2 and in which is placed oil Y, which provides lubrication to the movable elements; an electric motor, which has a rotor 4 and stator; piston 5, which provides delivery of refrigerant fluid in a pressurized state to the refrigeration system; cylinder 6, which is arranged on the upper side of rotor 4, in which piston 5 operates; crankshaft 7, which is supported by cylinder 6 , which transmits the rotary motion of the rotor 4 to the piston 5 by converting it into a linear motion and includes a lubricating channel 8 which supplies oil Y to the movable elements contained in the housing 2 on the upper side of the rotor 4 and, the oil extraction pipe 9, which is installed on the rotor 4 by a press-fit assembly method, the lower end of the oil extraction pipe is submerged in the oil Y in the oil tank 3 and its upper end extends upward fro...

Abstract

The present invention relates to a hermetic compressor (1) used in operating cooling devices like the refrigerator, comprising a casing (2) carrying the elements therein, an oil sump (3) forming the lower portion of the casing (2) and wherein oil (Y) is put providing the lubrication of the movable elements, an electric motor having a rotor (4) and a stator, a piston (5) providing the delivery of the refrigerant fluid in pressurized state to the refrigeration system, a cylinder block (6) wherein the piston (5) operates, a crankshaft (7) delivering the rotational movement of the rotor (4) to the piston (5) by changing it to linear movement and an oil pickup tube (9) mounted to the core of the rotor (4), the lower end of which is immersed into the oil (Y) in the oil sump (3) and the upper end extending upwards from the middle of the rotor (4) and which delivers the oil (Y) to the crankshaft (7) by sucking from the oil sump (3) and a hydrodynamic coupling (10) that transfers the rotational movement of the rotor (4) to the crankshaft (7).

Description

technical field [0001] The present invention relates to a reciprocating hermetic compressor in which the influence of inertial forces is reduced during start-up. Background technique [0002] The operation of the reciprocating hermetic compressors used in refrigerators is realized in two phases, start-up and continuous operation. The compressor motor reaches a speed of approximately 3000 rpm in only 0.5 seconds during start-up and consumes approximately 1650 VA of power. The compressor motor speed maintained at an average of about 3000 rpm after start-up and the electrical power consumed decreased to about 165 watts for continuous operation. The ratio between the power consumed in start-up and continuous operation is almost the same for hermetic compressors of different capacities. A hermetic compressor basically consists of a mechanical movement group including a piston, a piston rod and a crankshaft, and an electric motor that drives the mechanical movement group. The c...
