Abstract

The present invention provides a refrigerator, which improves convenience and appearance quality by reducing the installation space of the compressor, and reduces vibration and noise. It includes: a box body (1), a compressor (11), and an operation control unit. The box body (1) is provided with a storage compartment (15b) with a front door. The compressor (11) accommodates an electric element (110) composed of a stator (112) and a rotor (111) in an airtight container (103) having an upper container (102) and a lower container (101); ) driven compression element (113). The operation control unit performs torque control or stop control of the compressor (11). A plurality of legs (106) fastened to the lower container (101) are provided on the box body (1) via the elastic member (200). An elastic member (200) is attached to a plurality of substantially cylindrical pins (108) provided on the surface of the compressor installation surface (28b) of the case body (1).

Description

technical field [0001] The invention relates to a refrigerator which reduces vibration of a compressor. Background technique [0002] In conventional refrigerators, a machine room is generally arranged behind the lower part of the main body of the refrigerator, and a high-pressure side device of a refrigeration cycle such as a compressor is accommodated in the machine room. In recent years, from the viewpoint of improving usability and saving space, it has been required to improve the storage properties of refrigerators. In addition, from the viewpoint of environmental protection, it is also required to improve the energy saving performance of refrigerators. In order to meet these requirements, in the conventional refrigerator, a machine room is provided in the storage room on the top surface of the refrigerator main body, which is poor in usability, and on the upper back of the refrigerator main body, thereby improving convenience. Furthermore, a machine room whose temper...
