Title: REFRIGERATOR
Abstract:
A refrigerator (100) comprises a refrigerator body (10) comprising a food storage space (102) and a compressor chamber (103). A food storage container (11) is disposed in the food storage space (102), and a freshness preservation space is defined in the food storage container (11). The refrigerator (100) further comprises an air-regulating membrane component (30) configured to pass, through an air-regulating membrane, more oxygen than nitrogen in an air flow in the surrounding space of the air-regulating membrane component (30), to enter an oxygen-enriched air collection chamber; and an air pump component (40). An inlet end of an air pump (41) communicates, in a controlled manner, and via a pipe (51) and a pipe switching mechanism (52), with the oxygen-enriched air collection chamber, to pump and discharge the air out of the oxygen-enriched air collection chamber and the freshness preservation space, so as to maintain actual oxygen content in the freshness preservation space to be in a range of 2% to 19%.
