Problems solved by technology
And because the buckle itself has assembly stress after the air duct cover plate and the tank are assembled, and the surface temperature of the heater can be as high as 300°C or more during defrosting, and the high-temperature heat will radiate to the surroundings, so that the closer to the heater The buckle is continuously heated and finally reaches the softening temperature (such as 80°C) and softens and deforms. The deformed buckle cannot be restored, which will cause poor sealing between the air duct cover plate and the evaporator, resulting in excessive frosting on the evaporator, and even lead to wind. The road cover fell off, causing a fire safety accident
[0003] In order to solve the above problems, the existing solution is to design the shape of the heater or the structure of the air duct more complicated, but this will increase the production cost and process difficulty, and also sacrifice the defrosting efficiency

Embodiment approach
[0038] In the present invention, the flow guiding member may have any implementation manner. In order to further reduce the production cost, according to an embodiment of the present invention, the air guiding member may include two air guiding ribs 13 protrudingly formed on the first part 111 , and the two air guiding ribs 13 extend from the The part of the first part 111 located obliquely above the first buckle 12 respectively extends to the first buckle 12 on both sides (see figure 1 ).
[0039] Further, as a preference, such as figure 1 As shown, each of the guide ribs 13 may include an inclined section 131 and a vertical section 132, wherein: the inclined section 131 extends obliquely downward from the middle of the upper end of the first part 111 to the side of the first part 111 and the bottom end of the inclined section 131 is located above the first buckle 12; the vertical section 132 extends downward from the bottom end of the inclined section 131 to below the firs...

The invention relates to the field of refrigeration equipment and discloses an air duct cover plate and a refrigerator. The air duct cover plate comprises an assembly face. The assembly face is divided into a first part and a second part from bottom to top. The first part is used for being arranged close to a heater of the refrigerator. The second part is used for being arranged close to an evaporator of the refrigerator. First buckles are arranged on the two sides of the first part correspondingly. The first part is provided with a drainage part capable of draining water on the assembly faceto the first buckles. According to the air duct cover plate, by arranging the drainage part capable of draining water on the assembly face to the first buckles on the assembly face of the air duct cover plate, when the air duct cover plate is applied to the refrigerator and the refrigerator is defrosted, defrosted water drained by the drainage part can be used for cooling the buckles (namely the first buckles), close to the heater, of the air duct cover plate, and thus the buckles are prevented from being deformed due to heating. In addition, the air duct cover plate is low in production cost,simple in process and suitable for wide application and popularization.
Description
technical field [0001] The invention relates to the field of refrigeration equipment, in particular to an air duct cover plate and a refrigerator containing the air duct cover plate. Background technique [0002] At present, with the requirement of high volume ratio for air-cooled refrigerators, in order to reduce the space occupied by the air duct, ensure the defrosting efficiency of the refrigerator, and reduce the power consumption of defrosting, the structure design of the air duct is becoming more and more compact, making the air duct The distance between the channel cover plate and the defrosting heater is relatively close. In addition, in order to achieve the best defrosting efficiency, cost performance and simplification of the structure and process, the air duct cover plate is often made of PS or ABS material, and is connected with the refrigerator tank through the buckle arranged around it. And because the buckle itself has assembly stress after the air duct cover...
