Abstract
The utility model relates to a vacuum preserving box of refrigerator. The utility model is characterized in that the utility model comprises an independent closed box which comprises a box body and a box cover; the back part of the box cover is provided with an air extracting hole; the air extracting hole is provided with an one-way valve; the air outlet mouth with a sealing ring is communicated with the one-way valve; the box cover is provided with a pressure releasing button; the closed box is positioned in the refrigerator; a back plate of the refrigerator is provided with an air outlet passage which is communicated with a mini vacuum pump; the air outlet mouth of the closed box is detachably inserted and connected on the air outlet of an air outlet passage. The utility model can apply the two preserving methods of lower temperature and vacuum at the same time to complement disadvantages and enhance the preserving performance.
Description
Technical field
The utility model relates to the refrigerator annex, the supporting vacuum crisper in refrigerator of more specifically saying so.
Background technology
Fresh-keeping mode at present commonly used has two kinds, first vacuum freshness retaining, and it two is preservation by low temperature.Present vacuum freshness retaining is applied in the vacuum packaging of inner wrapping product more; Refrigerator is the representative of preservation by low temperature, but the fresh-keeping mode of refrigerator only is confined to can not obtain the environment of vacuum in the preservation by low temperature for a long time, thereby does not have to effectively utilize low temperature and the mutual supplement with each other's advantages of vacuum on fresh-keeping mode.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of refrigerator vacuum crisper is provided, two kinds of fresh-keeping modes of low temperature and vacuum are used in refrigerator simultaneously, having complementary advantages, in the hope of further improving freshness.
The utility model technical solution problem adopts following technical scheme:
Design feature of the present utility model is the independent closed enclosure that is made of box body and lid that is provided with, and the back of lid is provided with aspirating hole, takes out check valve is set on the aperture, and the exhaust nozzle that has sealing ring is communicated with check valve, and the pressure release button is set on lid; Described closed enclosure places between refrigerator indoor, and the exhaust passage be communicated with minipump is set in the refrigerator backboard, and the exhaust nozzle on the closed enclosure is removable to be plugged on the exhaust outlet of exhaust passage.
The utility model is under the refrigerated storage temperature environment, by reducing the boiling point of atmospheric pressure reduction water in the box, relies on the moisture gasification to take away the fruits and vegetables heat, reduces storage environment oxygen concentration inhibition fruits and vegetables self simultaneously and breathes, maintenance fruits and vegetables freshness.
The utility model vacuumizes processing by minipump to being located at closed enclosure indoor between refrigerator, keeps micro-vacuum in the box, makes it be hypoxia, prolongs the freshness date of fruits and vegetables to greatest extent.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, it is fast that the utility model makes fruits and vegetables cooling velocity in vacuum, and even, the cleaning of cooling can not polluted; The respiration that has suppressed fruits and vegetables, the time that freshness keeps is long with respect to other fresh-keeping mode.
2, the utility model makes the fruits and vegetables drying loss few, can not produce local desiccation, dehydration phenomenon; The moisture content on surface can evaporate in vacuum, avoids residual moisture to cause that fruits and vegetables are putrid and deteriorated.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram.
Fig. 2 is the utility model side-looking structural representation.
Fig. 3 is the utility model closed enclosure structural representation.
Fig. 4 is the utility model closed enclosure exhaust nozzle structural representation.
Number in the figure: chamber, 9 refrigerator backboards, 10 vavuum pumps, 11 exhaust passages between 1 box body, 2 lids, 3 aspirating holes, 4 check valves, 5 sealing rings, 6 exhaust nozzles, 7 pressure release buttons, 8 refrigerators.
Below, in conjunction with the accompanying drawings the utility model is further described by the specific embodiment.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment independently is provided with the closed enclosure that is made of box body 1 and lid 2, and the back of lid 2 is provided with aspirating hole 3, takes out check valve 4 is set on the aperture 3, the exhaust nozzle 6 that has sealing ring 5 is communicated with check valve 4, and pressure release button 7 is set on lid 2.
As shown in Figure 1 and Figure 2, closed enclosure places between refrigerator in the chamber 8, and the exhaust passage 11 that is communicated with minipump 10 is set in the refrigerator backboard 9, and exhaust nozzle on the closed enclosure 6 is removable to be plugged on the exhaust outlet of exhaust passage 11.
In concrete the enforcement, it is indoor that minipump 10 is arranged on freezer compressor.
When using the vacuum freshness retaining function, by setup program closed enclosure is vacuumized processing by control system, stop to bleed when reaching the vacuum of setting.Subsequently, promptly remain in the closed enclosure on the vacuum of setting, the moisture of fruits and vegetables gasifies at low temperatures, consumes more heat simultaneously, and the required latent heat overwhelming majority comes from the sensible heat amount that fruits and vegetables self discharge, and the result makes fruits and vegetables sub-cooled extremely promptly.Keep the hypobaric hypoxia state in the crisper simultaneously, can effectively suppress the fruits and vegetables respiration.
Closed enclosure is 8 interior taking-ups the from chamber between refrigerator directly, press pressure release button 7 before uncapping earlier and make the closed enclosure internal and external pressure balance, can uncap by nature subsequently.
When storing fruits and vegetables once more, the closed enclosure that stores food is put into chamber 8 between refrigerator, and its exhaust nozzle 6 directly is inserted on the exhaust outlet of refrigerator backboard 9, start minipump 10, make closed enclosure obtain exhaust,, keep this vacuum state to get final product until the vacuum that reaches setting.
Relevant parameter through experimental verification is:
Vacuum: 0.075MPa
The speed of evacuation: 〉=5L/min
Temperature of refrigerating chamber: 0～5 ℃.
