Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
The present invention proposes a kind of air duct cover board, as shown in Figure 1, Figure 2 and Figure 3, air duct cover board 1 include front shroud 4 and with it is preceding
The upper cover plate 5 that cover board 4 connects, when being assembled with the fan installation plate 3 in refrigerator box body, front shroud 4 is covered in fan installation plate 3
Side wall, upper cover plate 5 are covered in the upper wall of fan installation plate 3.Front air outlet 6, front air outlet 6 are provided on the surface of front shroud 4
Positioned at close to the position of upper cover plate 5.The both sides of front shroud 4 are respectively arranged with side air-out mouth 19, with reference to figure 6.It is arranged on upper cover plate 5
There is strip gab 8, wind guide strip 7 is provided in opening 8, opening 8 and wind guide strip 7 form upper air outlet.For ease of description, it defines
Side where front shroud 4 is the front side of air duct cover board 1, and the side where upper cover plate 5 is the upside of air duct cover board 1.Preceding outlet air
Mouthfuls 6 front side outlet air to air duct cover board 1, side outlet air of the side air-out mouth 19 to air duct cover board 1, upper air outlet is to air duct cover board 1
Upper side air-out effectively prevent frosting and the dew condensation phenomenon of air duct cover board 1 to realize the four sides air-out of air duct cover board 1.
Specifically, as shown in Figure 4 and Figure 5, multiple guiding rib positions, multiple guiding ribs are provided on the side of wind guide strip 7
Air-out passage 16 is formed between position, the wind that the wind turbine 20 being mounted on fan installation plate 3 is blown out flows out upper cover through air-out passage 16
Plate 5.Guiding rib position also functions to the reinforcement supporting role to wind guide strip 7 while playing the role of wind guiding.Guiding rib position can
With according to actual needs and simulation calculate and be specifically arranged so that the air-out effect that air duct cover board 1 is optimal.In the present embodiment
In, the guiding rib position for being located at the middle part of wind guide strip 7 is the bar shaped muscle 10 along the axis direction perpendicular to wind guide strip 7, bar shaped muscle 10
With at least one.Guiding rib position positioned at the both sides of bar shaped muscle 10 is arrow-shaped muscle 11, and the arrow of arrow-shaped muscle 11 is directed toward
Bar shaped muscle 10, arrow-shaped muscle 11 have at least two.Preferably, the quantity of bar shaped muscle 10 is 2, and the quantity of arrow-shaped muscle 11 is
8, respectively symmetrically it is arranged in the both sides of bar shaped muscle 10, i.e. every side of bar shaped muscle 10 is respectively arranged with 4 arrow-shaped muscle 11.
Further, along the direction from the middle part of wind guide strip 7 to the end of wind guide strip 7, the arrow angle of arrow-shaped muscle 11 gradually subtracts
It is small, convenient for the four direction outlet air all around for the wind direction upper cover plate 5 that wind turbine 20 is blown out.
Due to upper cover plate 5 close to freezing chamber side temperature will be less than temperature of the upper cover plate 5 far from freezing chamber side, i.e., on
Cover board 5 is less than the temperature of side of the upper cover plate 5 far from front shroud 4 close to the temperature of the side of front shroud 4, so upper cover plate 5 leans on
Nearby the side of cover board 4 is easier that frosting and dew condensation phenomenon occurs, then upper cover plate 5 needs more close to the side of front shroud 4

The setup error of wind guide strip 7 in order to prevent, it is ensured that the rear side that the front side air output of upper cover plate 5 is more than upper cover plate 5 goes out
Air quantity, as shown in figure 5, error protection protrusion 14 is provided on one end of a bar shaped muscle 10 wherein, error protection protrusion 14 and item
Shape protrusion 13 is located at the same side of wind guide strip 7.It is correspondingly provided in the opening 8 of upper cover plate 5 and connects with 14 cooperation of error protection protrusion
The groove 9 connect, as shown in Figure 2.
Buckle 12 is provided on wind guide strip 7, buckle 12 and the side of opening 8 are clamped, and wind guide strip 7 is fixedly connected on upper cover
On plate 5.In order to keep wind guide strip 7 and the connection of upper cover plate 5 more reliable, further, cylindricality is respectively set at the both ends of wind guide strip 7
Through-hole 15 is correspondingly provided with screw hole 17 on upper cover plate 5, is equipped with screw simultaneously on cylindricality through-hole 15 and screw hole 17, leads to
It crosses screw wind guide strip 7 and upper cover plate 5 link together.Certainly, the connection type of wind guide strip 7 and upper cover plate 5 is not limited to this
The realization method that embodiment is illustrated, in other embodiments, wind guide strip 7 can be connect with upper cover plate 5 by welding
Together.
The present invention also proposes a kind of refrigerator, including door lining 2, fan installation plate 3 and the wind turbine on fan installation plate 3
20, the air duct cover board 1 that the present embodiment is illustrated is provided on the side wall of fan installation plate 3.Front shroud 4 is covered in fan installation plate
3 side wall, upper cover plate 5 are covered in the upper wall of fan installation plate 3, by front air outlet 6 on air duct cover board 1, side air-out mouth and
Upper air outlet effectively prevent frosting and the dew condensation phenomenon of air duct cover board 1, improves the refrigeration effect of refrigerator.Further, door lining 2
On be provided with recess portion 18, between recess portion 18 and wind guide strip 7 have gap, to effectively prevent frosting and dew condensation phenomenon.Air duct cover board 1
