Description
Technical field
The utility model relates to a kind of refrigerator, particularly a kind of refrigerator that can regulate refrigerating chamber, refrigerating chamber gas composition.
Background technology
Existing refrigerator, the gas composition in the storeroom such as refrigerating chamber and refrigerating chamber can not regulate, and the composition of this storage indoor gas is identical with the composition of outdoor air, containing a large amount of steam and oxygen.Steam can form frost and be attached on the article that refrigerate in storeroom when meeting cold, oxygen can reserve rotten in accelerating chamber, affects fresh keeping time and the fresh-keeping effect of stored goods, be unfavorable for the storage of article.And the nitrogen in air contributes to the preservation refrigerating thing, as the air in refrigerator storeroom changed into nitrogen, greatly will extend preservation and the fresh keeping time of article, and there is no the appearance of this type of refrigerator at present.
Utility model content
The purpose of this utility model is the refrigerator providing a kind of adjustable storeroom gas composition, and the air displacement of freezing and refrigeration indoor can be become the nitrogen of high concentration by it, improves fresh-keeping effect, extends fresh keeping time.
The refrigerator of adjustable storeroom gas composition of the present utility model, comprise refrigerator body, and vacuum extractor and air-separating plant are set in this refrigerator body, the storeroom of this vacuum extractor and refrigerator is by pipeline connection, and the nitrogen outlet of air-separating plant is communicated in refrigerator storeroom.
This above-mentioned vacuum extractor comprises vavuum pump and check (non-return) valve, for being extracted out by the air of refrigerator indoor, avoids air return simultaneously.
This air-separating plant can be pressure swing adsorption air separator; Also can be film air-separating plant, for separating of air, obtain nitrogen-rich gas, to supply refrigerator storeroom.
The gauge tap of this vacuum extractor and air-separating plant is arranged in refrigerator doors, and timer is set, this switch be arranged in refrigerator doors is normally closed switch, disconnects when opening refrigerator doors, and timer is used for the running time of regulable control vacuum extractor and air-separating plant.
Because refrigerator of the present utility model arranges vacuum extractor and air-separating plant, at closing refrigerator behind the door, said apparatus is started working, and extracts the air in storeroom out and discharges, and supplements the nitrogen of high concentration.The food of storage is in the protection of nitrogen-rich gas environment, avoids and the oxygen in air and moisture, improve fresh-keeping effect and the storage time of food.
Accompanying drawing explanation
Fig. 1 is refrigerator structure schematic diagram of the present utility model;
Fig. 2 is the utility model refrigerator vacuum pumping device and air-separating plant working circuit diagram.
Detailed description of the invention
As shown in Figure 1, the refrigerator of adjustable storeroom gas composition of the present utility model is in refrigerator body 1, be provided with vacuum extractor and air-separating plant 5.This vacuum extractor is that a vavuum pump 8 connects a check (non-return) valve 12, this vavuum pump 8 is communicated to refrigerating chamber 11 and refrigerating chamber 9 respectively by pipeline, and be provided with air outlet port 13 and 3 at refrigerating chamber 11 and refrigerating chamber 9, the air of compartment interior can be extracted out by those air outlet ports, and by air outlet 7, air is discharged, check (non-return) valve 12 prevents air return.
In the present embodiment, air-separating plant 5 adopts pressure-variable adsorption partition method, and by pressure-variable adsorption effect, air separation is become nitrogen and other gas, in this device, valuable gases is nitrogen, and other gas is as waste gas.Nitrogen is communicated with refrigerator storeroom by pipeline, offers nitrogen outlet 2 in refrigerating chamber 9, offers nitrogen outlet 4 in refrigerating chamber 11, with the nitrogen needs of satisfied different storeroom.Other gas is discharged from blast pipe 6 as waste gas, and because this other gas is rich in oxygen, it suitably can also increase the oxygen concentration in room.
As shown in Figure 2, be the utility model refrigerator vacuum pumping device and air-separating plant working circuit diagram.Vacuum extractor of the present utility model and air-separating plant do not need long-term work, the working time can be set according to reservoir volume, and stream oriented device needs to work the air pressure that could keep in refrigerator storeroom simultaneously, therefore need the motor 15,16 of stream oriented device to be arranged in same circuit.Refrigerator doors 10 arranges gauge tap 14, and switch 14 is substantially identical with the light switch of current refrigerator, and when difference is refrigerator doors unlatching, switch 14 is in off-state, is in on-state during closedown.In addition in circuit contact timer 17, for controlling and regulate the time of stream oriented device work.
Above-mentioned refrigerator of the present utility model in use, after closing refrigerator door 10, turn on-switch 14, motor 15,16 rotates, vacuum extractor and air-separating plant are worked simultaneously, and the air in refrigerator storeroom extracted out by vacuum extractor, and the air separation outside refrigerator is become nitrogen and other gas by air-separating plant, and nitrogen is input in refrigerator storeroom, form air displacement.When after stream oriented device work to setting-up time, the air in refrigerator is replaced by the nitrogen produced, and Timer Controlling motor quits work.Work is carried out when next refrigerator doors is opened and closed.
