Abstract

The utility model relates to a vacuum constant humidity refreshing refrigerator or cooler. The body of the refreshing refrigerator or cooler is provided with a vacuum pumping device; the refrigerating chamber or freezer of the refreshing refrigerator or cooler is communicated with the atmosphere through a conduit and the vacuum pumping device; the conduit is series provided with a vacuum pumping controller which is connected with the vacuum pumping device; the refrigerating chamber or freezer is internally provided with a water holding salver. The refrigerator or cooler of the utility model can keep a certain vacuum degree in the storing environment; the aging and the deterioration process of the fruits and the vegetables is delayed in the environment with poor oxygen and low microscopic organisms; in the meantime, the fresh stored water in the water holding salver can evaporate automatically to make the storing environment hold saturated steam to avoid the shrinking of the fruits and the vegetables so as to guarantee the freshness of the fruits and the vegetables. The utility model integrates the refrigerating, vacuum technique and the constant humidity refreshing technique, not only convenient for the life of people, but also promoting the improvement of the technique with good economic benefit and social benefit.

Description

Vacuum constant humidity fresh-keeping refrigerator or refrigerator

Technical field

The utility model relates to a kind of refrigerator or refrigerator, relates in particular to a kind of have vacuum constant humidity fresh-keeping function refrigerator or refrigerator.

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 can cause more than 90% in the storage environment rotting 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 name and has been called: " low vacuum fresh-keeping refrigerator or refrigerator ", the patent No. is: 01274453.0 utility model patent, 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 that fruits and vegetables are under the environment of dry lack of water, moisture content is lost comparatively fast in the tissue, and fruits and vegetables can lose freshness equally because of dehydration.

The utility model content

The purpose of this utility model is to provide a kind of vacuum constant humidity fresh-keeping refrigerator or refrigerator that can prolong the food fresh keeping phase greatly.

In order to achieve the above object, the technical solution of the utility model is to have adopted a kind of vacuum constant humidity fresh-keeping refrigerator or refrigerator, the casing of refrigerator or refrigerator is provided with vacuum extractor, the refrigerating chamber of refrigerator or refrigerator or refrigerating chamber are communicated with atmosphere by conduit and vacuum extractor, be equipped with on the conduit and vacuumize controller, vacuum extractor with vacuumize controller and link to each other, be provided with the pallet that is filled with water in refrigerating chamber or the refrigerating chamber.

The described pallet that is filled with water is arranged at below the evaporation plate as drip tray.

Because refrigerator of the present utility model or refrigerator can make the certain vacuum of maintenance in the storage environment, fruits and vegetables have delayed the old and feeble and rotten process that becomes in the environment of anoxic, low microorganism, simultaneously, the fresh water storage that is filled with water in the pallet can be evaporated automatically, make and keep saturated vapor in the storage environment, avoid the drying shrinkage of fruits and vegetables tissues, thereby guaranteed the freshness of fruits and vegetables.The utility model is melted into a whole refrigeration, vacuum and constant humidity preservation technique, has promptly made things convenient for people's life, has promoted technological progress again, and favorable economic benefit and social benefit are arranged.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the casing back of vacuum constant humidity fresh-keeping refrigerator of the present utility model or refrigerator has installed a vavuum pump 1 additional, vavuum pump 1 is communicated with refrigerating chamber and refrigerating chamber by conduit 2, be equipped with check valve 3 on the conduit 2 as air intake control valve, the air inlet of conduit 2 is provided with filter 4, fast aeration valve 5 is equipped with at the door handle place of casing, vavuum pump 1 with vacuumize controller 6 and link to each other, the pallet 8 that is filled with water as drip tray is installed below the evaporation plate 7 of refrigerating chamber.

During use, close body to the doorstep, vavuum pump 1 promptly begins to vacuumize under the control that vacuumizes controller 6, and when being extracted into certain vacuum (generally taking out 90% air), vavuum pump 1 promptly quits work under the control that vacuumizes controller 6, because string has check valve 3 on the conduit 2, air outside can not reflux, and in storage, the fresh water storage meeting in the pallet 8 that is filled with water is evaporated automatically, make the relative humidity in the storage environment reach 90%, play preservation.When opening the door, when pulling handgrip, fast aeration valve 5 is opened, and makes inside and outside air pressure balance, can be the door breakdown, and the storage thing of taking.

Claims

1, a kind of vacuum constant humidity fresh-keeping refrigerator or refrigerator, the casing of refrigerator or refrigerator is provided with vacuum extractor, the refrigerating chamber of refrigerator or refrigerator or refrigerating chamber are communicated with atmosphere by conduit and vacuum extractor, be equipped with on the conduit and vacuumize controller, vacuum extractor with vacuumize controller and link to each other, it is characterized in that: be provided with the pallet that is filled with water in refrigerating chamber or the refrigerating chamber.

2, vacuum constant humidity fresh-keeping refrigerator according to claim 1 or refrigerator is characterized in that: the described pallet that is filled with water is arranged at below the evaporation plate as drip tray.
