The condenser 30 of the present embodiment has a flat rectangular parallelepiped shape as a whole, and is installed such that its fins extend in the depth direction of the case 10, so that the air entering from the air suction port 221 flows along channels between the fins to exchange heat, and then flows toward the heat dissipation fan 50 from the space between the condenser 30 and the back plate 240. The radiating fins are arranged in parallel along the depth direction, and after air enters from the airflow suction inlet 221, the air can smoothly and fully contact with each fin through gaps among the radiating fins and exchange heat, so that the radiating effect is greatly enhanced. In some embodiments, the condenser 30 may be disposed to be inclined upward from front to back in the depth direction of the tank 10, and the air sucked in the airflow suction port 221 may be effectively utilized, so that the contact area of the air and the condenser 30 is increased sufficiently, and the heat dissipation effect is enhanced.

In a preferred embodiment, the section of the back plate 240 facing the condenser 30 is a continuous plate surface, i.e., there are no louvers in the plate section of the back plate 240 facing the condenser 30. The heat dissipation airflow entering the compressor compartment 200 is sealed at the condenser 30, so that the ambient air entering from the airflow suction inlet 221 is more concentrated at the condenser 30, the heat exchange uniformity of each condensation section of the condenser 30 is ensured, a better heat dissipation airflow path is favorably formed, and a better heat dissipation effect is achieved.

The press hatchcover 210 of the present embodiment includes a sloping front cover 211 and a top cover 212. The inclined front cover 211 is inclined upward from the front side of the airflow suction opening 221 and the airflow discharge opening 222 in the depth direction of the housing 10 from the front to the rear. The top cover 212 extends horizontally rearward from the rear end of the inclined front cover 211 to meet the back plate 240. That is, the press deck 210 is disposed obliquely, so as to save the internal space of the box 10 as much as possible, and increase the volume of the storage space 300 above the press deck 200, thereby improving the overall space utilization. The projection of the cabin 200 on the horizontal plane is located behind the projection of the evaporator 60 on the horizontal plane, that is, the cabin 200 and the evaporator 60 are staggered in the horizontal direction, so that the arrangement height of the evaporator 60 is reduced, and the volume of the storage space 300 is increased. The inclined front cover 211 may be spaced apart from and parallel to the inner container inclined portion by an angle of inclination in a range of 30 ° to 40 °, for example, 33 °, 35 °, 38 °, and preferably 36.7 °.

The rear sidewall of the partition plate 270 may form a limit groove adapted to the shape of the front end of the cooling fan 50, so that the front portion of the cooling fan 50 is installed in the limit groove. The partition plate 270 is connected to the radiator fan 50 and partitions the air suction port 221 and the air discharge port 222. The partition plate 270 may cooperate with the wind blocking plate 272 to restrict the airflow from the airflow inlet 221 to the condenser 30, so that the airflow can sufficiently exchange heat with the condenser 30, and the airflow is prevented from being directly guided to the compressor 20 side, thereby reducing the airflow rate at the condenser 30 side, and the airflow can take away the heat generated by the operation of the compressor 20 when passing through the compressor 20 side, and then lead to the airflow outlet 222 from the gap in front of the compressor 20, thereby being discharged out of the compressor compartment 200.

The wind guard 272 extends from the rear end of the partition plate 270 toward the front of the compressor 20, and the projection of the tip thereof in the depth direction of the casing 10 is aligned with the middle of the compressor 20. After the wind shield 272 is provided in the compressor compartment 200, the heat dissipation space in the compressor compartment 200 is further compressed for the fully-embedded refrigerator, and therefore the wind shield 272 is not likely to be too long at the end point. The wind shield 272 has a starting point at the position of the heat dissipation fan 50 to prevent heat dissipation and a terminal point at the middle of the compressor 20 to be aligned, thereby guiding the heat dissipation air flow to the whole surface of the compressor 20. In the process of the operation of the compressor 20, the heat can be radiated to the maximum extent, the air volume loss of the radiating airflow from the initial point to the high-pressure point is prevented, and the temperature of the compressor 20 can be effectively reduced. In addition, due to the arrangement of the wind shield 272, the air volume convolution can be reduced, so that the temperature of the condenser 30 is reduced, and after the temperature of the condenser 30 is reduced, effective energy saving can be realized.

The partition plate 270 is opened at a side thereof facing the condenser 30 with a pipe hole 273 for passing the drain pipe 110 of the refrigerator therethrough and leading to the evaporating dish 250. The arrangement of the pipe holes 273 can effectively save the space in the compressor room 200, and further enable the structure in the box body 10 to be more compact, so that the space utilization rate of the whole refrigerator is higher.

The condenser 30 of the present embodiment has a flat rectangular parallelepiped shape as a whole, and is installed such that its fins extend in the depth direction of the case 10, so that the air entering from the air suction port 221 flows along channels between the fins to exchange heat, and then flows toward the heat dissipation fan 50 from the space between the condenser 30 and the back plate 240. The radiating fins can be arranged in parallel along the depth direction, and after air enters from the airflow suction inlet 221, the air can smoothly and fully contact with each fin through gaps among the radiating fins and exchange heat, so that the radiating effect is greatly enhanced. In some embodiments, the condenser 30 may be disposed to be inclined upward from front to back in the depth direction of the tank 10, and the air sucked in the airflow suction port 221 may be effectively utilized, so that the contact area of the air and the condenser 30 is increased sufficiently, and the heat dissipation effect is enhanced. In other embodiments, the condenser 30 may also use a microchannel heat exchanger.

The refrigerator of the present embodiment may be further provided with a weather strip 280. The wind-shielding strip 280 is disposed on the lower surface of the press support plate and configured to isolate the airflow suction opening 221 from the airflow discharge opening 222 and prevent air sent out from the airflow discharge opening 222 from flowing back into the airflow suction opening 221. The external air enters the cabin 200 through the airflow suction port 221 located at one side of the weather strip 280, passes through the condenser 30 and the compressor 20, and finally flows out of the airflow discharge port 222 located at the other side of the weather strip 280, so that the discharged air is prevented from reentering the airflow suction port 221, and the air is circulated in a small range near the box body 10, thereby reducing the heat dissipation efficiency.

A press electrical control board 70 is also provided in this embodiment. The press control board 70 is disposed adjacent to the side plate 230 on a side of the compressor 20 and is configured to provide an electrical control signal to the compressor 20. When the cooling fan 50 fails, the temperature of the condenser 30 rises, the compressor 20 operates for a long time, the temperature in the high-pressure cabin 200 further rises, the heat can be transmitted out from the gap between the wind shield 272 and the side plate 230, the temperature in the low-pressure cabin 200 is reduced, and the occurrence of equipment damage in the cabin 200 is reduced. In addition, the press electric control board 70 is arranged separately from the compressor 20, when the temperature of the compressor 20 rises, the temperature rise of the press electric control board 70 cannot rise too high, and the risk of component damage is reduced.

The refrigerator of this embodiment may also be configured such that when the compressor 20 is continuously turned on for more than 2h, and when the temperature of the sensor in the storage space 300 does not decrease or the decrease rate is lower than a certain threshold, the refrigerator sends a fault signal to the cooling fan 50, so as to improve the user experience.

The air guide assembly 290 may be further disposed in the pressing machine compartment 200 of the present embodiment. The air guide assembly 290 is disposed at the outer circumference of the condenser 30, and is configured to guide the air sucked from the air suction port 221 completely through the condenser 30, so as to prevent the air from being discharged from the outer circumference of the condenser 30 and flowing to the heat dissipation fan 50 only from the space between the condenser 30 and the back plate 240. The heat radiation airflow can be fully contacted with the condenser 30, and the heat radiation performance is enhanced.

The wind shield 272 can have a certain blocking effect on the heat dissipation airflow, so that the heat dissipation airflow can completely flow through the compressor 20 and fully contact with the compressor 20 to exchange heat, the heat dissipation structure of the refrigerator is optimized, and the heat dissipation performance of the refrigerator is further improved.

Further, the bottom plate 220 of the compressor compartment 200 is provided with an airflow suction inlet 221 in a front area of the condenser 30, and a heat dissipation fan 50 is disposed between the compressor 20 and the condenser 30, wherein the heat dissipation fan 50 is configured to promote formation of a heat dissipation airflow which enters from the airflow suction inlet 221, flows through the condenser 30 for heat exchange, then passes through the compressor 20, and is discharged to the airflow discharge outlet 222 through the gap. The condenser 30 and the compressor 20 are cooled by the same cooling airflow, so that the internal structure is simplified, the environment is more protected, and the energy is saved.
