In some embodiments of the present utility model, in some embodiments of the present utility model, it can be opened up on cylinder 22 There are multiple micropores, storage space 211 and controlled atmosphere space are via multiple microporous connectivities.Micropore is also referred to as air pressure balance Hole, each micropore can be millimetre-sized micropore, such as a diameter of 0.1mm to 3mm of each micropore, preferably 1mm, 1.5mm etc.. Set multiple micropores that the pressure in controlled atmosphere space can be made to be unlikely to too low, the setting of multiple micropores will not also make controlled atmosphere Nitrogen in space flows to big storage space 211, even if flowing is also that very little is even negligible, does not interfere with The preservation of food in controlled atmosphere space.It can be also not provided with some alternative embodiments of the present utility model, on cylinder 22 micro- Hole, even if so, also there is the gas such as substantial amounts of nitrogen to exist in controlled atmosphere space, user pull the drawer out 23 when, also not , then can be significantly laborsaving compared to existing vacuum storing room with too sweat.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model many Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the utility model spirit and scope The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new The scope of type is understood that and regarded as to cover other all these variations or modifications.
