Document Type and Number:
WIPO Patent Application WO/2020/151592
Kind Code:
A1
Abstract:
A refrigerating and freezing device, comprising: a box body (20), in which a controlled atmosphere preservation space (25) is defined; a controlled atmosphere membrane assembly and a suction pump (30), which are disposed in the box body (20), the suction pump (30) being configured to draw out gas in the controlled atmosphere preservation space (25) so that air in the controlled atmosphere storage space (25) flows to the controlled atmosphere membrane assembly, and under the action of the controlled atmosphere membrane assembly, a part or all of the oxygen-enriched gas in the air in the controlled atmosphere preservation space (25) traverses the suction pump (30) and is discharged from the controlled atmosphere storage space (25); and a silencer (90), which is connected in series at a suction side or exhaust side of the suction pump (30), so that the suction air flow or exhaust air flow of the suction pump (30) flows through the silencer (90) so as to reduce the suction noise or exhaust noise of the suction pump (90).
