Abstract

The utility model relates to a vacuum refreshing refrigerator. The fruits and the vegetables box in the refrigerating chamber of the refrigerator is provided with a sealing cover; the fruits and the vegetables box cavity is connected with the air out of the refrigerator through a suction nozzle, a conduit, an air admission control valve and a vacuum pumping device which are connected in turn; the vacuum pumping device is connected with a vacuum pumping controller. Because just the vacuum in the pumping in the fruits and the vegetables box is pumped, the normal opening of the refrigerator door and the normal accessing of the fruits, the vegetables and the beverages are not hampered; furthermore, just vacuum pumping to the fruits and the vegetables box can make the people put the fruits and the vegetables which need long term storage into the fruits and the vegetables box; the vacuum pumping area is small, can save energy. Furthermore, after the vacuum pump is communicated with the refrigerating chamber, the whole refrigerating chamber has the function of refreshing; the function is expanded and the using is more convenient. The undersurface of the evaporating board of the refrigerating chamber is movably provided with a water holding salver which has water carrying function; the water holding salver not only has the function of carrying water, but also can make the refrigerating environment in saturated humidity to prevent the fruits and the vegetables from shrinking because of water scarcity.

Description

Vacuum freshness retaining refrigerator

Technical field

The utility model relates to a kind of refrigerator, relates in particular to a kind of refrigerator with vacuum freshness retaining function.

Background technology

Vacuum freshness retaining is to utilize the environment that vacuumizes a hypoxemia of quick formation or ultralow oxygen, remove volatility in fruits and vegetables organization internal and the storage environment gas that accelerates the ripening fast, the after-ripening and the senescence process of fruits and vegetables have been delayed greatly, suppress brown stain, it is hard to protect crisp guarantor, prolongs the shelf life, vacuumizes the radix that can also significantly reduce germ, the microorganism that causing more than 90% rots in the storage environment is got rid of outside storage environment, delayed the rotten process that becomes of fruits and vegetables to a great extent." Chinese utility model patent communique " announced a kind of patent No. and has been: 01274453.0, name is called: the utility model patent of " low vacuum fresh-keeping refrigerator or refrigerator ", the technology of vacuumizing has been applied to refrigerating field, technical essential is to be provided with a vavuum pump or air exhauster in the casing back of refrigerator or refrigerator, and link to each other with the refrigerating chamber or the refrigerating chamber of refrigerator or refrigerator by air intake duct, during work, make and be in low vacuum in the case, anoxic, dry environment, to scheme the prolonging shelf life, realize fresh-keeping purpose, but the problem of this technology is, integral body vacuumizes, comparatively power consumption does not have specific aim, and some greengrocery of temporarily depositing vacuumizes fresh-keeping effect and not obvious, in addition, the fruits and vegetables long period is deposited under the dry environment, is easy to dehydration, is unfavorable for fresh-keeping on the contrary, protect crisp, protect hard.

The utility model content

The purpose of this utility model is to provide a kind of vacuum freshness retaining refrigerator, can need the fruits and vegetables of long period storage to carry out storage in vacuum to some targetedly.

To achieve these goals, the technical solution of the utility model is to have adopted a kind of vacuum freshness retaining refrigerator, fruit and vegetable box in the refrigerating chamber of this refrigerator is provided with seal cover, the fruit and vegetable box inner chamber links to each other with the refrigerator outer air by suction nozzle, conduit, air intake control valve and the vacuum extractor that links to each other successively, vacuum extractor with vacuumize controller and link to each other.

On the seal cover of fruit and vegetable box charge valve is housed.

The refrigerating chamber of refrigerator links to each other with vacuum extractor with conduit by suction nozzle fixing on its inwall, is equipped with air intake control valve on the conduit.

Below the refrigerating chamber evaporation plate, be provided with a pallet that is filled with water as drip tray.

Described air intake control valve is check valve, and the charge valve with the assembling of door handle interlock is housed on refrigeratory body.

Because only to vacuumizing in the fruit and vegetable box, do not hinder the normal access of the normal unlatching of refrigerator doors and vegetables, beverage class; Moreover, only fruit and vegetable box is vacuumized, can make people that the fruits and vegetables of need Long-term Storage are put into fruit and vegetable box, it is little, comparatively energy-conservation to vacuumize the space.In addition, vavuum pump can also make whole refrigerating chamber possess the vacuum freshness retaining effect after being communicated with refrigerating chamber, is expanded on the function, and is more convenient to use; The movable pallet that is filled with water with water receiving effect that is provided with promptly can play the effect that collects cooling water below the evaporation plate of refrigerating chamber, also can make cold storage environment be in saturated humidity, has prevented the lack of water drying shrinkage of fruits and vegetables.Fridge freshness retaining of the present utility model, energy-conservation, the excellent popularization using value arranged.

Fig. 2 is the structural representation of fruit and vegetable box among Fig. 1.

The specific embodiment

As shown in Figure 1 and Figure 2, refrigerator of the present utility model mainly is to be provided with the vavuum pump 1 that vacuumizes in the back of refrigerator body, vavuum pump 1 with vacuumize controller 16 and link to each other, vavuum pump 1 is communicated with the box chamber 3 of two fruit and vegetable boxes by conduit 2, the head of conduit 2 links to each other with suction nozzle 4 on being fixed on the box wall, wears filter 5 on the suction nozzle 4.Seal cover 6 is arranged on the fruit and vegetable box, ball valve 7 as charge valve is housed on the seal cover 6, be provided with a sealing gasket 18 between seal cover 6 and the fruit and vegetable box, also be equipped with check valve 8 on the conduit 2 as air intake control valve, vavuum pump 1 also is communicated with refrigerating chamber 10 by another conduit 9, the head of this conduit 9 is equipped with the suction nozzle that is fixed on the refrigeration locular wall, filter 12 also is housed on the suction nozzle, be equipped with check valve 13 and control ball valve 14 on this conduit 9, below refrigerating chamber evaporation plate 17, be movably equipped with a pallet 11 that is filled with water as drip tray, the charge valve 15 with the door handle interlock is housed on the door body of refrigerator.

During use, close body vavuum pump 1 to the doorstep, promptly under the control that vacuumizes controller 16, begin fruit and vegetable box is vacuumized, when being extracted into certain vacuum (generally taking out 90% air), vavuum pump 1 promptly quits work under the control that vacuumizes controller 16, owing on the conduit check valve is housed, air outside can not reflux.When getting the fruits and vegetables in the fruit and vegetable box, open refrigerator doors, the ball valve 7 on the twisting fruit and vegetable box seal cover 6, during inside and outside air pressure balance, can take away seal cover 6, take out article, when needs vacuumize whole refrigerating chamber 10 simultaneously, can open corresponding ball valve, refrigerating chamber 10 is communicated with vavuum pump gets final product.When vacuum reached requirement in the refrigerating chamber, vavuum pump 1 quit work, and also is equipped with the check valve 8 as air intake control valve on the conduit 2, and air can not reflux.When needs are opened refrigerator doors, pull door handle, ball valve 7 conductings, inside and outside air pressure balance, the door body can be opened.
