In one aspect, an embodiment of the present invention provides a frame structure 100, and the frame structure 100 is installed in a housing of a refrigerator. As shown in fig. 1, the frame structure 100 includes: the first support member 110, the second support member 120 are distributed side by side, and the first wind shielding member 130 is arranged between the first support member 110 and the second support member 120; the first support member 110 and the second support member 120 are matched to form a heater installation position and an evaporator installation position, and the heater installation position, the evaporator installation position and the first wind shielding member 130 are sequentially distributed from bottom to top.

Note that the heater mounting position is used for mounting the heater 200 of the refrigerator, and the evaporator mounting position is used for mounting the evaporator 300 of the refrigerator.

As described above, in the frame structure 100, the first wind shielding plate 130 can slow down the upwelling speed of the hot air heated by the heater 200, prolong the time of the hot air flowing through the evaporator 300, improve the defrosting efficiency of the evaporator 300, shorten the working time of the heater 200, and further reduce the energy consumption of the heater 200, so that the refrigerator can save energy and power.

In some embodiments of the present invention, the second support 120 has a mounting groove 120a thereon; the first end of the first wind shielding member 130 is fixedly connected to the first supporting member 110, and the second end of the first wind shielding member 130 is inserted into the mounting groove 120a (see fig. 2), wherein the first end and the second end of the first wind shielding member 130 are distributed oppositely. Thus, the assembly and disassembly of the frame structure 100 are facilitated.

Alternatively, the first end of the first wind shielding member 130 may be integrally molded or welded with the first support member 110.

Further, in some embodiments of the present invention, the first wind shielding member 130 may allow the liquid drops on its surface to flow toward its edge by gravity. The frosted vapor can be liquefied into small droplets after encountering the first wind shielding member 130, and the small droplets flow to the edge of the first wind shielding member 130 by virtue of the self gravity to be converged and fall, so that the collection of the droplets is facilitated.

The second wind blocking member 140 and the third wind blocking member 150 may block the hot air heated by the heater 200 from flowing upward from both sides of the evaporator 300, so that the hot air flows toward the evaporator 300 in a concentrated manner, thereby improving defrosting efficiency of the evaporator 300 and shortening the defrosting efficiency.

In particular, in some embodiments of the present invention, the second wind shielding member 140 and the third wind shielding member 150 can make the liquid drops on their surfaces flow to their edges by gravity, respectively. The water vapor after frosting meets the second wind shielding part 140 and the third wind shielding part 150 and then can be liquefied into small liquid drops, and the small liquid drops flow to the edges of the second wind shielding part 140 and the third wind shielding part 150 by means of the gravity of the small liquid drops to be converged and fall, so that the collection of the liquid drops is facilitated.

Optionally, the mounting member 170 has a screw mounting hole, so that the frame structure 100 can be fixed in the refrigerator casing by screws, which facilitates the assembly and disassembly of the frame structure 100.

In some embodiments of the present invention, as shown in fig. 1, the first support 110 and the second support 120 are respectively disposed in a plate-like structure.

Note that the overlapping hole 100a is provided in a structure that matches the outer contour of the evaporator 300.

On the other hand, an embodiment of the present invention further provides a refrigerator, including: a housing, and a heater 200, an evaporator 300 and the frame structure 100 of any one of the above disposed in the housing; the heater 200 is installed at a heater installation position of the frame structure 100; the evaporator 300 is mounted at an evaporator mounting location of the frame structure 100.

As described above, the first wind shielding plate 130 of the frame structure 100 can slow down the upwelling speed of the hot air heated by the heater 200, prolong the time of the hot air flowing through the evaporator 300, improve the defrosting efficiency of the evaporator 300, shorten the working time of the heater 200, and further reduce the energy consumption of the heater 200, so that the refrigerator saves energy and electricity.

In some embodiments of the present invention, as shown in FIG. 1, the heater 200 includes at least one set of heating lines; each group of heating lines comprises: a first pipeline 210, a second pipeline 220 arranged in parallel, and a third pipeline 230 connected between the first pipeline 210 and the second pipeline 220. The first pipeline 210 and the second pipeline 220 which are distributed in parallel can heat the air by the heater 200 for two times, and the heating efficiency of the heater 200 is improved.

Alternatively, the third pipeline 230 may have a bending radius of 38mm to 39mm, and may be, for example, 38mm, 38.1mm, 38.2mm, 38.3mm, 38.4mm, 38.5mm, 38.6mm, 38.7mm, 38.8mm, 38.9mm, 39 mm. Therefore, a certain distance between the first pipeline 210 and the second pipeline 220 can be ensured, and the surface temperature of the first pipeline 210 and the second pipeline 220 is prevented from being too high due to baking.

Alternatively, as shown in fig. 2, the number of the heating lines is 2, the second lines 220 of the 2 heating lines are communicated with each other through a communication line 250, and one end of each first line 210, which is far away from the third line 230, is communicated with an upwardly extending fourth line 240. Alternatively, the lead-through line 250 is a line bent in a horizontal plane, and the fourth line 240 is a line bent in a vertical plane.

Alternatively, as shown in fig. 1, 3 and 4, the second pipeline 220 is located below the first pipeline 210, and the second pipeline 220 includes a first pipe section and a second pipe section which are connected and have an included angle, and the distance between the first pipe section and the second pipe section gradually decreases in a direction away from the first wind shielding member 130. Thus, the heater 200 is closer to the drain outlet below the evaporator 300, which can effectively heat the area around the drain outlet and avoid the ice blockage at the drain outlet.

In some embodiments of the present invention, as shown in fig. 3, the evaporator 300 includes: three coils 310 distributed side by side. Thus, on the premise that the evaporation area of the evaporator 300 is not changed, the distribution of the evaporator 300 in height is reduced, so that the heat of the heater 200 is concentrated, and the defrosting efficiency of the evaporator 300 by the heater is improved; the defrosting time of the heater 200 is reduced, and the energy consumption of the refrigerator is reduced.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
