Abstract

The invention discloses a rotary hermetic compressor which comprises a hermetic container, a motor assembly and a compressor assembly, wherein the motor assembly is installed at the upper part of the hermetic container; the compressor assembly is installed at the lower part of the hermetic container; the hermetic container comprises an upper cover, a shell and a lower cover; the motor assembly comprises a stator, a rotor installed in the center of the stator and a rotating shaft; the compressor assembly comprises an upper bearing, a lower bearing, an air cylinder and a muffler; an exhaust pipe is arranged on the side surface of the upper part of the top circle of the shell; an installing hole is formed on the side surface of the lower part of the top circle of the shell; a connecting terminal is welded on the shell through the installing hole; an overload protective device is arranged above the stator and inside the shell; and a line card is arranged at one side of the overload protective device. Because the exhaust pipe is installed on the side surface of the upper part of the top circle of the shell, and the connecting terminal is installed on the lower side surface of the shell, the invention reduces the overall height of the compressor, has a compact structure, and simultaneously reduces vibration and noise.

Description

technical field [0001] The invention belongs to a rotary compressor for an air conditioner, and in particular relates to an exhaust pipe arranged on the upper side of the casing of the compressor, and a power connection terminal arranged on the lower side of the casing, which can reduce the overall height of the compressor and reduce vibration and noise , Compact rotary hermetic compressor. Background technique [0002] Generally speaking, a compressor is a part of a refrigeration cycle device, and it is a device that pressurizes a refrigerant to make the pressure and temperature of the refrigerant suitable for a specific purpose. The refrigeration cycle device consists of a compressor, a condenser, an expansion device, and an evaporator, and all components are connected to each other to form a closed circulation system. [0003] This refrigeration cycle device compresses the low-temperature and low-pressure refrigerant gas sucked into the compressor, and discharges it in a...
