Problems solved by technology

[0014] In addition, if the airtight container 52 is in contact with the cylinder group 59 constituting the compression member 63, etc., since both are formed of metal, metal chips (fine fragments) will be generated.
If it gets between the cylinder block 59 and the crankshaft 68 which is a typical shaft slip, there is a possibility of abnormal wear and loss of compression (lockup)
[0015] On the other hand, in the compressor 50, there is attached a refrigerant piping (not shown) that conveys the compressed refrigerant 53 to the next step, such as a discharge capillary. If the parts constituting the compression member 63 are in frequent contact, metal fatigue will concentrate and accumulate in the contact parts, and eventually the discharge pipe will be brittle and the compressor 50 will not be able to perform the prescribed function.

Abstract

A highly reliable refrigerator which is rendered silent by suppressing abnormal noise from a compressor due to impact of collision against the box body of refrigerator when a rotary door is closed. The refrigerator comprises a box body (101) arranged with a storage compartment (106) provided with opening/closing rotary doors (113a, 113b) on the front. A recess (120) curved toward the uppermost containing space (122a) side in the storage compartment (106) is provided across the top and back of the box body (101). The compressor (150) is installed in the recess (120). The rotary doors (113a, 113b) are split to open at the middle with the right and left sides as fulcrums, and the compressor (150) is arranged so as to avoid the projection line from the front side of the split line. Abnormal noise from the compressor (150) is suppressed by separating it from the projection line from the front side of the split line where angular momentum is highest thereby reducing impact being transmitted to the compressor (150) through the refrigerator box body when the rotary doors (113a, 113b) are closed.

Description

technical field [0001] The present invention relates to a refrigerator in which a compressor is mounted in a concave portion on a top surface of the refrigerator. Background technique [0002] Recently, from the viewpoint of protecting the global environment, the energy-saving trend of refrigerators has become stronger and stronger. In addition to improving its usability and storage, it is also required to further reduce its noise from the viewpoint of improving comfort. . [0003] In the prior art, such a refrigerator has always adopted a method in which a compressor or the like forming a machine room is arranged on the top surface of the refrigerator body or the upper back of the refrigerator body which is poor in usability from the user's side (for example, Japanese Patent Laid-Open , Special Publication No. 11-183014). [0004] Hereinafter, the above-mentioned conventional refrigerator will be described with reference to the drawings. Fig. 22 is a structural sectional...
