The wind-shielding strip 280 is arranged on the lower surface of the box body 10, and the middle part of the wind-shielding strip 280 is a flexible section 283 that can be bent under force, so that the wind-shielding strip 280 can be placed on the box body by bending the flexible section 283. The space between the bottom of 10 and the supporting ground of the refrigerator is divided into the wind-shielding state of the air intake area communicated with the air inlet 2220 and the exhaust area communicated with the air outlet 2230 . The flexible section 283 of the windshield strip 280 can be bent to isolate the airflow inlet 2220 from the airflow outlet 2230, so as to prevent the heat dissipation airflow from circulating in a small area at the bottom of the box body 10 and improve heat dissipation efficiency.

As shown in Figure 4-Figure 8. The bottom wall 220 includes a press support plate 221 , an air inlet plate 222 and an air outlet plate 223 . The press support plate 221 is disposed at the rear of the bottom wall 220 . The air inlet plate 222 extends forward from the front end of the compressor supporting plate 221 where the condenser 30 is located, and an airflow suction port 2220 is opened thereon. The air outlet plate 223 extends forward from the front end of the area where the compressor 20 is located in the compressor supporting plate 221 , and an airflow outlet 2230 is opened thereon. The wind-shielding strip 280 extends linearly along the front end of the press support plate 221 when the flexible section 283 is not bent. That is, the wind-shielding strip 280 has two states. In the process of actual use, the wind-shielding strip 280 is in the wind-shielding state (as shown in FIG. 4 ), and the wind-shielding strip 280 is bent to isolate the airflow inlet 2220 from the airflow outlet 2230 , to avoid the circulation of heat dissipation airflow in a small area at the bottom of the box body 10, and improve the heat dissipation efficiency; Extending in a straight line, it is convenient to cooperate with the packing box during transportation and handling to avoid bump damage.

The windshield strip 280 includes a first shielding section 281 , a flexible section 283 and a second shielding section 282 . The first shielding section 281 is fixed between the front end of the press support plate 221 and the air inlet plate 222 . One end of the flexible section 283 is connected to one end of the first shielding section 281 located in the middle of the box body 10 . The second shielding section 282 is connected to the other end of the flexible section 283 , and is arranged at the front area of the compressor 20 , and its extension direction changes according to the bending degree of the flexible section 283 . The first shielding section 281 is always fixed on the lower surface of the box body 10, and the second shielding section 282 can rotate on the lower surface with the bending of the flexible section 283 to separate the airflow inlet 2220 from the airflow outlet 2230 , to prevent the heat dissipation air from circulating in a small area at the bottom of the box body 10, and improve the heat dissipation efficiency. In the storage state, the second shielding section 282 is fixed between the front end of the press support plate 221 and the air outlet plate 223 , and cooperates with the packing box during transportation to avoid collision damage.

When the wind-shielding strip 280 is in the wind-shielding state, the flexible section 283 is bent into an arc shape, and makes the second shielding section 282 extend obliquely forward from between the wind inlet plate 222 and the wind outlet plate 223, and the inclination direction is It is biased toward the side of the compressor 20 from the rear to the front. By cooperating with the lower surface of the box body 10 through the second shielding section 282, the exhaust area is limited to the front side of the box body 10, so that the heat dissipation airflow can quickly leave the surrounding environment of the refrigerator, and avoid the hotter heat dissipation airflow from being scattered into the embedded refrigerator after the heat exchange is completed. In the storage space of the refrigerator, the environment where the refrigerator is located is relatively hot, which increases the energy consumption of the refrigerator. The air intake area is restricted by the first shielding section 281 to the area around the box body 10 other than the air exhaust area. The gas enters the compressor cabin 200 through the airflow suction port 2220 communicated with the air intake area, and is fully exchanged with the condenser 30. The heat then enters the side of the compressor 20 through the cooling fan 50, takes away the heat generated by the operation of the compressor 20, enters the exhaust area from the air outlet 2230, and then leaves the bottom of the box body 10.

The cross-section of the wind strip 280 is L-shaped, wherein the horizontal side of the wind strip 280 is attached to the lower surface of the box body 10, and the vertical side of the wind strip 280 is vertically arranged to the lower surface of the box body 10, and vertically The height of the straight side matches the height from the lower surface of the box body 10 to the supporting ground of the refrigerator, so as to fully separate the airflow inlet 2220 from the airflow outlet 2230, and reduce the heat dissipation air flow from the airflow outlet 2230 directly from the windshield strip 280 The possibility of returning to the air intake area in the gap with the supporting ground prevents the cooling air from circulating in a small area at the bottom of the box body 10 and improves the cooling efficiency.

The refrigerator of this embodiment further includes a partition 270 . The partition 270 is arranged between the air inlet plate 222 and the air outlet plate 223 and is arranged upwards to separate the front area of the compressor 20 and the condenser 30 in the compressor room 200 . The partition 270 includes a bottom plate 276 , a first side plate 271 and a second side plate 272 . The bottom plate 276 is located between the air inlet plate 222 and the air outlet plate 223 . The first side plate 271 extends upward from an end of the bottom plate 276 close to the air outlet plate 223 to isolate the front area of the compressor 20 . The second side plate 272 extends upward from an end of the bottom plate 276 close to the air inlet plate 222 to isolate the front area of the condenser 30 . The separator 270 isolates the airflow inlet 2220 from the airflow outlet 2230, so that the heat dissipation airflow must pass through the airflow inlet 2220, the condenser 30, the heat dissipation fan 50, and the compressor 20 before being discharged from the airflow outlet 2230, so that the heat dissipation is more sufficient . A claw 275 for fixing the second shielding section 282 is disposed on the lower surface of the bottom plate 276 so as to limit the second shielding section 282 when the windshielding strip 280 is in the windshielding state.

By connecting and fixing the partition member 270 and the cooling fan 50, the components in the compressor cabin 200 are connected more closely and the integrity is stronger. Moreover, the above-mentioned installation method using the limiting groove 274 is convenient and fast, which simplifies the installation steps of the cooling fan 50 . And the cooling fan 50 extends from the rear of the first side plate 271 to between the compressor 20 and the condenser 30 . The compressor compartment 200 is divided into the compressor side and the condenser side by the heat dissipation fan 50 and the partition 270, and the heat dissipation air flow and the condenser 30 fully exchange heat before entering the compressor 20 side through the heat dissipation fan 50, and taking away the heat of the compressor 20 The box body 10 can be discharged from the airflow outlet 2230 only after the heat has been run.

The drain pipe 110 of the built-in refrigerator in this embodiment extends from the drain port at the bottom of the liner above the compressor compartment cover plate 210 to the evaporating dish 250 through the area between the first side plate 271 and the second side plate 272 . The setting of the reserved opening between the first side plate 271 and the second side plate 272 can effectively save the space in the compressor cabin 200, and further make the structure in the box body 10 more compact, so that the overall space utilization rate of the refrigerator is higher.

After the windshield 273 is installed in the compressor cabin 200, the heat dissipation space in the compressor cabin 200 will be further compressed for fully embedded refrigerators, so the end of the windshield 273 is not easy to be too long. The starting point of the windshield 273 is located at the position of the heat dissipation fan 50 to prevent the diffusion of heat dissipation, and the end point is aligned at the middle of the compressor 20, so that the heat dissipation airflow can be directed to the entire surface of the compressor 20, so that the compressor 20 can dissipate heat to the greatest extent and prevent the heat dissipation airflow When the initial point moves to the commanding height, the air volume loss can effectively reduce the temperature of the compressor 20 . In addition, the setting of the windshield 273 can reduce the whirling of the air volume, lower the temperature of the condenser 30, and realize effective energy saving.

The condenser 30 of this embodiment is in the shape of a cuboid as a whole, and is installed so that its cooling fins extend along the depth direction of the box body 10, so that the air entering from the airflow suction port 2220 flows along the passage between the cooling fins for exchanging air. The heat then flows from the gap between the condenser 30 and the back plate 240 to the cooling fan 50 . The cooling fins are arranged in parallel along the depth direction. When the air enters from the air inlet 2220, it can smoothly pass through the gaps between the cooling fins to fully contact each fin and exchange heat, which greatly enhances the cooling effect. In some embodiments, the condenser 30 can be arranged obliquely upward from the front to the rear along the depth direction of the box body 10, and the air sucked in the airflow suction port 2220 can be effectively used, so that the contact area between the air and the condenser 30 is increased to enhance heat radiation. In some other embodiments, the condenser 30 may also use a micro-channel heat exchanger.

In the built-in refrigerator of this embodiment, an air guide assembly 290 may also be provided in the compressor cabin 200 . The air guide assembly 290 is arranged on the outer periphery of the condenser 30, and is configured to guide the air sucked in from the airflow inlet 2220 to completely pass through the condenser 30, so as to prevent the airflow from escaping from the outer periphery of the condenser 30, and only from the condenser 30 and the back plate 240 The space between flows to the cooling fan 50. The heat dissipation airflow can be fully contacted with the condenser 30 to enhance heat dissipation performance.
