Problems solved by technology
[0011] However, because the inner walls of the freezer compartment and the refrigerator compartment of the conventional refrigerator are made of ABS resin, as shown in FIG. waiting time
For the above reasons, if the refrigerating operation is performed after the defrosting operation, since condensed water condenses on the inner wall of the refrigerating chamber, it will re-freeze and continue to form thicker frost, thereby not only reducing the heat exchange efficiency, but also forming channels Damping, reducing refrigeration performance

Embodiment Construction
[0033] As shown in Fig. 3 and Fig. 4, the refrigerator adopting the defrosting structure of the present invention has a freezer compartment F formed on its lower side and a refrigerated compartment on its upper side inside the refrigerator main body 52 whose front is open. R; in front of the above-mentioned refrigerator main body 52, a freezer compartment door 54a and a refrigerator compartment door 54b are hingedly connected; a refrigeration cycle including evaporators 60a, 60b is built in the inner wall of the above-mentioned refrigerator main body 52; A portion of the inner casing 52c on the side of the refrigerating compartment where the evaporator 60b contacts is covered with a hydrophilic film.
[0034] Here, the above-mentioned refrigerator main body 52 is formed by foaming a heat insulating material 62 between the outer shell 52a forming the appearance and the inner shells 52b, 52c when various components are built in; , forming the above-mentioned freezer compartment ...

A defrosting structure of the refrigerator, including: the main body of the refrigerator forms the freezing chamber and the cold-storage chamber in it; the evaporator touches the interior wall of the freezing chamber or the cold-storage chamber; the refrigeration cycle that connects with the evaporator and sets at one side of the refrigerator main body; the hydrophilicity film forms at the interior wall of the freezing chamber and / or the cold-storage chamber that connect with evaporator, and drops the condensation water that coagulates at the interior wall of the freezing chamber and / or the cold-storage chamber. The invention can prevent the icing phenomenon of the condensation water during the freezing and cold-storage running process.
Description
technical field [0001] The invention relates to a defrosting structure of a refrigerator. Background technique [0002] Generally speaking, refrigerators are divided into direct cooling type and indirect cooling type according to their cooling methods. Among them, direct cooling type refrigerators are equipped with evaporators on the inner walls of their freezing chambers and refrigerating chambers, so that the cold air formed around the evaporators is cooled. Natural convection cools the freezer and refrigerator; while the indirect refrigeration refrigerator is equipped with an evaporator on the inner wall of the freezer, and a fan is installed on the cold air circulation channel, so that the cold air formed around the above evaporator passes through the fan. Forced air supply and cooling of the freezer and refrigerator. [0003] Existing refrigerators adopt the direct cooling type, such as figure 1 As shown, in the interior of the refrigerator main body 2 formed by the o...
