  • Porous part for refrigerators, and method of producing the same and refrigerator
    Patent number: 6672100
    Abstract: In this porous part producing method, a head part (11A, 11B) in the interior of a compressor, which is a sintered part, is subjected at least to vacuum substitution or heat blow cleaning, whereby after oils causing contamination and/sludge, such as rust-preventive oil, in the head part (11A, 11B) in the interior of the compressor is discharged therefrom, the head part (11A, 11B) is immersed in alkyl benzene type oil serving as refrigerator oil. Thereby, deterioration-inducing substances in the head part (11A, 11B) in the interior of the compressor is replaced with the refrigerator oil; thus, it is possible to produce a porous part which will not bring about contamination and/or sludge even if used as a component for refrigerators for a long time.
