Description of the drawings
Fig. 1 is the structure diagram of the utility model air duct sealing structure.
Fig. 2 is the sectional view at A-A in Fig. 1.
Fig. 3 is the enlarged drawing at B in Fig. 2.
Specific embodiment
To make the purpose of this utility model, technical solution and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings
The utility model is further described in example.It should be appreciated that specific embodiment described herein is only used to explain this reality
With novel, it is not used to limit the utility model.
Please referring also to Fig. 1-Fig. 3, air duct sealing structure described in the utility model embodiment, including：First air duct seals
Part 100 and the second air duct sealing element 200 being adapted to the first air duct sealing element 100, first air duct sealing element 100 are set
Primary sealing area 110 is equipped with, it is close that second air duct sealing element 200 is provided with second be bonded with the primary sealing area 110
Cover 210；Several card convexs 111,210 corresponding position of the secondary sealing area setting are provided on the primary sealing area 110
There are several card slots 211.
Form air duct chamber in first air duct sealing element 100 and second air duct sealing element 200, cold air is from described
It is flowed through in the chamber of air duct.
The card convex 111 forms sealing labyrinth with the card slot 211.The card convex 111, the card slot 211 all can be
It is multiple, it is preferable that the card convex 111, the card slot 211 are 2, are separately positioned on the both sides of the air duct chamber.The card
Convex 111 with the card slot 211 be continuous Back Word type, naturally it is also possible to be other shapes be adapted to the air duct chamber, can entirely
Orientation seals the air duct chamber.The sealing labyrinth that the card convex 111 is formed with the card slot 211 for obstructing cold air, reduces
Flowing velocity of the cold air in sealing labyrinth, prevents cold draining.
After the primary sealing area 110 and the secondary sealing area 210 assemble, horizontal by an inclination angle.Described
One sealing surface 110 and the secondary sealing area 210 are arranged in parallel, and the primary sealing area 110 and the secondary sealing area 210 fill
After matching, horizontal by an inclination angle, the high one end of the primary sealing area 110 is close to refrigerator back, the primary sealing area
110 low one end in this way in assembling, can easily be directed at the position of the card convex 111 and the card slot 211 close to refrigerator front
It puts, convenient for assembling, meanwhile, the primary sealing area 110 and the secondary sealing area 210 are from close refrigerator back to refrigerator front
It tilts, is conducive to the export of condensed water.The inclination angle is 0 ° ~ 90 °, it is preferable that the inclination angle is 10 ° ~ 60 °.
