With the rotation center O of the blower 15 1 As the center of a circle, take D 1 The circle with the diameter of =d+ [ delta ] D is denoted as circle O 1 Wherein Δd > 0, and Δd: d E [0.4,0.8]. Wherein, straight line L and circle O 1 Tangent, i.e. the straight line L being a circle O 1 Is a tangent to (a); i.e. the lower boundary of the damper fixing foam piece 4 is a circle O 1 Is a tangent to (a) the line of (b). In this embodiment, the centrifugal fan 15 is arranged, and the air flow is thrown out from the tangential direction of the centrifugal fan 15; the arrangement above makes the first air opening 60 on the air door fixing foam piece 4 correspond to the air flow thrown out from the tangential direction of the centrifugal fan 15, thereby reducing the air flowSo that the air flow thrown out by the centrifugal fan 15 can enter the first air port 60 in a large amount, and the smoothness of the air path can be ensured, thereby realizing the maximization of the air quantity.
Further, straight line L and circle O 1 The included angle of the straight line with the horizontal diameter is denoted as A, wherein A is 20 DEG, 30 DEG]A=25° in this embodiment. The lower boundary straight line L of the air door fixing foam piece 4 is obliquely arranged, so that the defrosting water of the refrigerating air door 14 after defrosting flows out along the lower boundary straight line L, the refrigerating air door 14 can be dried after defrosting, and the phenomenon that the refrigerating inner door is frozen due to the fact that the defrosting water is not discharged in time after defrosting is avoided.
The freezing air duct unit 2 comprises a heat insulating plate 20 arranged in the freezing air supply air duct 130, and the heat insulating plate 20 is positioned on one side of the fan 15 close to the freezing air duct cover plate 26. The side of the freezing air duct cover plate 26, which is far away from the freezing air duct backboard 25, is provided with a freezing air duct decorative plate 28.
In summary, the switching air duct unit has a small number of parts, and the assembly strength of the switching air duct unit and the freezing liner or the refrigerating liner in the switching air duct unit meets the installation requirement, so that the switching air duct unit is convenient to install; on the other hand, after the refrigerator is integrally assembled, the whole connection strength is strong under the interaction of the freezing inner container, the refrigerating inner container, the switching air duct unit and the refrigerator shell.
In addition, a plurality of parallel refrigerating air supply openings are arranged on the refrigerating air supply air duct, so that cold air in the refrigerating air supply air duct enters the refrigerating chamber layer by layer, the refrigerating chamber is refrigerated more uniformly, and the full-space cooling of the refrigerating chamber is realized.
Furthermore, the refrigerating air duct unit is positioned at the rear side of the refrigerating chamber, and based on the specific design structure, a protruding bag structure is not required to be formed in the refrigerating chamber because of the arrangement of the refrigerating air door, so that the volume ratio is increased, and the attractiveness is improved due to the planarization arrangement of the refrigerating air supply air duct; the refrigerating air supply duct communicated with the switching air duct is only required to be arranged at one side of the refrigerating chamber for conveying cold air; the arrangement ensures that the internal structure of the refrigerating chamber is simple, and the storage space of the refrigerating chamber can be improved. In addition, the containing part for containing the refrigeration air door is integrally formed on the refrigeration air duct backboard, so that the integrity of the refrigeration air duct unit is improved; in addition, the refrigerating air door is installed in the accommodating part through the air door fixing foam piece, other fixing parts are not needed, and the installation and the disassembly are simple and convenient.
