[specific embodiment]
With reference to figure 2, the refrigerator with external vacuum freshness retaining container of the present utility model comprises the casing 1 with inner accepting space, and this inner accepting space is divided into separate upper refrigerator compartment and lower freezer compartment and can be sealed by door body 2 respectively.The device of extracting vacuum is set in casing 2, and what this extracting vacuum device comprised the below that is arranged on casing 1 is provided with vavuum pump 3, and is arranged on the extraction joint 5 on the rear wall 10 of refrigerating chamber.In other real-time modes of the present utility model, the position of extracting plug 5 also can be arranged on other positions of casing 1, for example is arranged on the outer surface of casing 1.Extracting joint 5 connects on the vavuum pump 3 by the passage in the insulation foaming layer that is arranged on casing 14.An independent draws pipeline (being a flexible pipe 6 an in the present embodiment) end has suction nozzle, this suction nozzle is detachably connected to and extracts on the joint 5, the other end has joint (participating in Fig. 3 and Fig. 5), this joint is detachably connected on the vacuum freshness retaining container 7 of a casing outside that is arranged on refrigerator, vacuum tank 7 has and is used to hold the main part of putting into article wherein and the opening that is used for extracting vacuum, and the sealing device of salable this opening is set at opening part.Advantage of the present utility model is: at first, the position of vavuum pump 3, passage 4 and extraction joint 5 does not take the receiving space of casing 1; Secondly, the independent draws pipeline separates fully with refrigerator and vacuum freshness retaining container 7, when not needing extracting vacuum, the independent collection of independent draws pipeline can be placed in the idle place, can not take the inner accepting space of refrigerator, can not hinder refrigerator to use the normal function of refrigerator again; Once more,, can utilize this independent draws pipeline, expand the scope of application of vacuum plant greatly to heteroid vacuum freshness retaining container extracting vacuum by adjusting the structure of independent draws pipeline and the jointing of vacuum freshness retaining container 7.Below describe two kinds of different vacuum freshness retaining containers 7 in detail.
With reference to figure 3 and Fig. 4, the vacuum freshness retaining container 7 of a kind of embodiment of the present utility model comprises the plastic box body 70 with inner accepting space, puts into the article 8 that need vacuum to preserve in this plastic casing.The loam cake of box body 70 has opening, and the sealing device of box body 70 is installed on this opening, and in the present embodiment, the sealing device is an one-way sealing valve 71.This check valve 71 comprises the valve seat 72 that is positioned at the opening below, is positioned at above the opening and the valve body 73 that is connected with valve seat 72, and is installed in the spool 74 in the valve body 73.Valve body 73 has an opening outwardly, has internal thread on the sidewall of this opening, has the external screw thread with this screw-internal thread fit on independent draws pipeline and the joint 60 that this valve body 73 docks.Spool 74 is the plastic bodies that cover the softness on the check valve passage that runs through valve seat 72 and valve body 73, when the vavuum pump startup vacuumizes for box body 70 by being connected to the independent draws pipeline that extracts on the joint 5, this softness plastic body is upwards sucked up, thereby open the check valve passage air in the box body 70 is extracted out; After box body 70 was evacuated and pulls out joint, because the outer air pressure of box body 70 is greater than the air pressure in the box body 70, the pressure that spool 74 is produced by the inner air and outer air pressure differential covered on the check valve passage, realize to box body 70 from movable sealing.Be unlocked in order to make spool 74 not be subjected to unexpected external power, be tucked into protection spool 74 in the opening of valve body 74 with reference to the valve gap 76 of 4, one protectiveness of figure.
With reference to figure 5 and Fig. 6, the vacuum freshness retaining container 7 ' of a kind of embodiment of the present utility model comprises a polybag 70 ' that has inside to pack into to need the article 8 that vacuum preserves, and the opening wrapping of polybag 70 ' is on the another kind of joint 60 ' of independent draws pipeline.In the present embodiment, the one-way sealing valve need be set at the opening of polybag 70 '.After startup vavuum pump 3 vacuumizes for polybag 70 ', the position 71 ' of at first polybag 70 ' being closed on joint 60 ' seals with heat sealing machine, perhaps tighten this position sealing with binding, then polybag 70 ' is pulled out from joint 60 ', just the polybag after vacuumizing 70 ' freely can be saved in suitable place.The advantage of present embodiment is, can expand the scope of application of antistaling vacuum container greatly to various difference vary in size the polybag extracting vacuum and the independent preservation of shape.
