Publication number: 20120301334Abstract: In a conventional compressor, since a motor and a mechanical section of the compressor are disposed in one and the same closed container, the motor is exposed to high-temperature coolant and heated, and the efficiency of the motor is lowered. Further, during the operation of the compressor, the coolant circulating in the refrigerating cycle conveys additional heat generated by the motor coil. Thus the efficiency of the refrigerating cycle is lowered. The compressor according to the present invention includes a compression chamber divided into a closed chamber and an open chamber separated by a magnetic induction plate from each other. The closed chamber is filled with high temperature and pressure coolant and the rotor of the motor is disposed in the closed chamber, and the stator of the motor is disposed in the open chamber.Type: ApplicationFiled: May 24, 2012Publication date: November 29, 2012Applicant: Hitachi Appliances, Inc.Inventors: Baiying HUANG, Hiroyasu YONEYAMA, Kazuo SAKURAI
