The working condition of the refrigerator that foundation the foregoing description is provided describes below.

Working condition when at first, illustrating that with reference to Fig. 1 refrigerator doors 15 is closed.

If the refrigerator starting is started working compressor 19, then 17 pairs of cold-producing mediums of evaporimeter gasify.The heat of case 12 in vaporized cold-producing medium absorbs in evaporimeter 17, the air of storeroom 13 inside is cooled thus, when storeroom 13 temperature inside drop to uniform temperature when following, stops the work of compressor 19.

Along with the prolongation of time, storeroom 13 temperature inside rise, and the cold air of storeroom 13 inside drops to storeroom 13 bottoms, so produces the temperature difference between the upper and lower of storeroom 13.At this moment, compressor 19 and blowing unit 40 are started working.

If compressor 19 work, then evaporimeter 17 gasifies to cold-producing medium once more and the air of storeroom 13 inside is cooled off beginning, and blowing unit 40 sucks the cold air that accumulates in storeroom 13 bottoms by inflow entrance 20a to cold air path 20 simultaneously.That is, blowing unit 40 and compressor 19 linkage works.

The cold air that is inhaled into cold air path 20 continues to rise and is directed into the cold air guide channel 30 that is connected with cold air path 20.The cold air that is directed into cold air guide channel 30 is ejected into the top of storeroom 13 by the jet that is formed on refrigerator doors 15 bottoms.Thus, the temperature to storeroom 13 tops compensates.

And, when the cold air on storeroom 13 tops drops to storeroom 13 bottoms and when causing the temperature on storeroom 13 tops to rise, the coldplate 65 that the cold air that is sprayed by jet cools off cools off surrounding air lentamente, thereby the temperature on storeroom 13 tops is compensated.

Secondly, the working condition when illustrating that with reference to Fig. 5 refrigerator doors 15 is opened.

Blowing unit 40 worked on when as shown in Figure 5, refrigerator doors 15 was opened.Blowing unit 40 is drawn into cold air path 20 by the cold air that inflow entrance 20a will accumulate in storeroom 13 bottoms, and the cold air that is drawn into cold air path 20 flows out by flow export 20b again.At this moment, because the area of flow export 20b is less than the area of inflow entrance 20a, therefore the cold air that flows out from flow export 20b sprays with stronger pressure.Thus, the cold air that flows out from flow export 20b plays the effect of air curtain, thereby stops that storeroom 13 air outside flow into storeroom 13 inside.

The embodiment that only cold air path is formed on body interior is illustrated above, but cold air path is not to be formed on body interior, and its embodiment can carry out various changes, is formed on the main body outside as using special pipeline etc.

In sum, according to the cool air injection of refrigerator provided by the present invention by will dropping to the storeroom bottom to storeroom top, thereby can prevent the phenomenon that the temperature distributing disproportionation of storeroom upper and lower is spared.

And, can stop also that when opening refrigerator doors the storeroom air outside flows into compartment interior.
