Description
Technical field
The present invention relates to refrigerator art more particularly to a kind of wind cooling refrigerators.
Background technique
Wind cooling refrigerator has many advantages, such as that of good preservation effect, refrigeration is fast and environmentally friendly, and wind cooling refrigerator is compared to shared by direct cooling refrigerator
Some market shares are also increasing.
Air duct in existing wind cooling refrigerator mostly uses greatly plastics air duct part, and the component part of plastics air duct part is more, especially
In three-door refrigerator (including refrigerating chamber, temperature-changing chamber and freezing chamber), plastics air duct part is generally comprised for it: refrigerating chamber air supply tube, cold
Room backwind tube, temperature-changing chamber air supply tube, temperature-changing chamber backwind tube etc. are hidden, corresponding pipe joint is also more, in the work of wind cooling refrigerator
Make aspect of performance, air hose and pipe joint are more, be easy to cause air duct circuit not smooth and seeping phenomenon occur, and are easier
Existing gas leak phenomenon, wind cooling refrigerator is very high for the sealing requirements in air duct, if the sealing in air duct goes wrong, will result in cold
The loss of wind, and then reduce the service performance of entire refrigerator；It, then can phase since components are more in wind cooling refrigerator manufacture view
In requisition for more processing step, it is also desirable to which more manual operation is completed to assemble, and causes assembly efficiency low.
Air-supply wind path and return air wind path all in refrigerator can be integrated in the foam of air duct by air duct foam, in this way can be effective
The technical problem for avoiding amount of parts more and causing assembly efficiency low, so, air duct foam gradually replaces plastics air duct
Part.
But refrigerating chamber return air wind path and temperature-changing chamber return air wind path are combined into all the way by the air duct foam in existing three-door refrigerator
Return air wind path structure, since the temperature of refrigerating chamber is generally 2 DEG C~8 DEG C, the temperature of temperature-changing chamber is generally -20 DEG C~5 DEG C, from cold
After hiding the air-flow of room discharge and the air-flow confluence of temperature-changing chamber discharge, it is easy to lead to the problem of ponding in wind path, can produces over time
Raw condensation, icing phenomenon.
So ponding in return air wind path can effectively be avoided by designing one kind, ensure that the refrigerator of service performance is to need at present
It solves.

The working performance of foam member, and then improve the service performance of wind cooling refrigerator.
As shown in Figure 6, Figure 7, air duct foam seat 1 and air duct foam cap 2, which are interlocked, forms refrigerating chamber air-supply wind path 3, cold
Hide room return air wind path 4, temperature-changing chamber air-supply wind path 5 and temperature-changing chamber return air wind path 6, i.e. refrigerating chamber air-supply wind path 3, refrigerating chamber return air wind
Road 4, temperature-changing chamber air-supply wind path 5 and temperature-changing chamber return air wind path 6 are integrated in the foam element of air duct, also just without special design air supply tube
Road, air return pipeline and pipe joint, the structure for reducing amount of parts, simplifying entire air duct foam element, so not
Only avoid air-flow that seeping phenomenon occurs in pipe joint or pipeline knee, meanwhile, assembly technology difficulty can also be reduced,
Assembly efficiency is improved, and the seal failure rate of pipeline and pipe joint can be reduced, ensures the leakproofness of air duct foam element, especially
It is wind cooling refrigerator higher for sealing requirements, and sealing effect is more obvious.
In some embodiments, air duct foam seat 1 and air duct foam cap 2 are fastened by concaveconvex structure in one, for example,
One of setting groove in air duct foam seat 1 and air duct foam cap 2, the connection matched with groove is arranged in another
Column, connecting column are stuck in groove；For another example being arranged on the joint face of one of them in air duct foam seat 1 and air duct foam cap 2
Card slot is arranged on another corresponding joint face in the protrusion circumferentially laid along joint face, and protrusion is fastened in card slot.By recessed
The air duct foam seat 1 and air duct foam cap 2 that male structure is interlocked, formed sealing two air-supply circuits and two return air wind paths,
It, can be in the edge of air duct foam seat 1 and air duct foam cap 2 in order to further increase the leakproofness in air-supply circuit and return air wind path
