Description of drawings
Fig. 1 is the structural representation of refrigerator temperature bascule preferred embodiment of the present utility model.
The specific embodiment
Further specify refrigerator temperature bascule provided by the utility model below in conjunction with accompanying drawing, but therefore the utility model is not subjected to any restriction.
Fig. 1 shows the schematic partial cross-sectional view of a kind of preferred implementation of the present utility model, as can be seen, cold storage box 1 is arranged on the outer top surface of refrigerating chamber casing 2, its lower surface forms heat conduction with casing 2 and contacts, its upper surface forms heat conduction with evaporator pipeline 3 and contacts, and cold-storage liquid 4 is housed in the cold storage box 1.It can also be seen that from figure cold storage box 1 is wrapped up by foaming layer 5 with refrigerating chamber casing other parts are the same with the top of evaporator pipeline 3, thereby the cold that the device that avoids evaporating produces outwards scatters and disappears.
In the present embodiment, cold storage box 1 is bonded in the box top outside by thin double faced adhesive tape, and evaporator pipeline 3 also is bonded on the upper surface of cold storage box 1 by thin double faced adhesive tape.Because double faced adhesive tape is very thin, and area is very little, can influence the thermal conductivity between cold storage box 1 and box top 2 and the evaporator pipeline 3 hardly.In the embodiment that is more preferably, can adopt heat-conducting glue to realize the connection of above-mentioned parts.In addition, under the prerequisite that can guarantee excellent sealing, evaporator pipeline 3 is passed from cold storage box 1 with cold-storage liquid directly contact, thereby obtain better heat exchanger effectiveness.
In the process of refrigerator start refrigeration, the cold-producing medium evaporation heat absorption in the evaporator pipeline 3 reduces the cold-storage liquid temp in the cold storage box 1.Thereby the air of the cold-storage liquid of low temperature by box top and refrigerating chamber internal upper part carries out exchange heat reduces air themperature.It will be appreciated by those skilled in the art that because evaporimeter does not directly contact with casing, but directly contact with cold storage box; Very low temperature (about 25 ℃) absorbs by means of cold-storage liquid in the cold storage box and cushions on the evaporimeter, rises to about 0 ℃ after arriving the casing top surface, is lower than refrigerating chamber internal upper part air themperature slightly, does not therefore exist to freeze and the situation of defrost.And, by with the heat exchange of cold-storage liquid, the temperature of refrigerating chamber internal upper part air effectively reduces, and further promotes to refrigerate the balance of indoor temperature by free convection.In addition, refrigerator stops refrigeration when shutting down, and the cold-storage liquid in the cold storage box is emitted the cold that gathers at this moment, can keep in the refrigerating chamber, and especially the temperature of refrigerating chamber upper air has also been slowed down the variations in temperature that refrigerator startup-shutdown process causes effectively.
In the present embodiment, cold storage box 1 is thin rectangular box body, and it is installed on the outside of refrigerating chamber end face, and its position is close to the door of refrigerating chamber.Because the position at door place is the weak link of whole box body sealing, and forms exchange heat owing to open often with the external world, so be the higher zone of refrigeration indoor temperature.The utility model is provided with the cold storage box 1 interior temperature of balance refrigerating chamber more effectively herein.
