For example, fruit food is suitable for storing in the refrigerating space 121, and meat food is suitable for storing in the freezing space.

As can be appreciated by those skilled in the art, the refrigerator 100 of the present embodiment may further include an evaporator 101, a compressor 104 and a condenser 105 arranged in the compressor compartment 180, a throttling element (not shown), and the like. The evaporator 101 is connected to the compressor 104, the condenser 105, and the throttling element via a refrigerant pipeline to form a refrigeration cycle. When the compressor 104 is started, the temperature is lowered to cool the air flowing therethrough.

As shown in FIG. 1 , the bottom of the box body defines a press chamber 180 , that is, a press chamber 180 is defined at the lower and rear of the storage liner 130 . In the embodiment shown in FIG. 2 , the bottom of the box body also defines a press chamber 180 . The nacelle (not shown in Figure 2). Compressor 104 and condenser 105 are spaced laterally within compressor compartment 180 .

In particular, the bottom wall of the box defines a laterally arranged first bottom opening 110a located in front of and below the condenser 105 and a second bottom opening 110b located in front of and below the compressor 104, in one embodiment, as a cooling fan The cross-flow fan 106 is configured to draw ambient air from the first bottom opening 110a and/or from the second bottom opening 110b, and force the ambient air to pass through the condenser 105, the compressor 104, and then flow forward from below the bottom wall of the box into the surrounding environment, so as to form a heat dissipation airflow circulation under the bottom wall of the box, cooling the condenser 105 and the compressor 104, without increasing the interval between the back of the built-in refrigerator 100 and the cabinet, reducing the space occupied by the refrigerator 100, and ensuring Refrigeration effect of the built-in refrigerator 100 .

In this embodiment, the cross-flow fan 106 is used as the cooling fan, and the cross-flow fan 106 is disposed on the front side of the compressor chamber 180 . Compared with the scheme in which the axial flow fan is used as the cooling fan, and the compressor 104, the axial flow fan, and the condenser 105 are arranged laterally in sequence, in this embodiment, the cross flow fan 106 is located on the front side of the compressor chamber 180, and the compressor The compressor 104 and the condenser 105 are not in the same lateral direction, which can reduce the lateral width dimension of the compressor compartment 180, so that the refrigerator 100 can be adapted to a smaller platform, and in the case where the space in the width direction needs to be compressed, the compressor compartment 180 can still be guaranteed. Has good heat dissipation performance.

The arrangement position of the cross-flow fan 106 and the circulation path of the heat-dissipating airflow have various forms as follows.

Driven, the ambient air around the first bottom opening 110a enters the cross-flow fan 106, and flows through the condenser 105 and the compressor 104 in turn, taking away the heat of the condenser 105 and the compressor 104, and then flows from the second bottom opening 110b. It flows out of the compressor compartment 180, that is, it flows to the bottom wall of the box (the space between the bottom wall of the box and the supporting surface of the refrigerator 100), and flows forward to the surrounding environment, thereby forming a circulation of heat dissipation air to ensure The heat dissipation effect of the compressor cabin 180.

In the vapor compression refrigeration cycle, the surface temperature of the condenser 105 is generally lower than the surface temperature of the compressor 104 , so in the above process, the outside air is made to cool the condenser 105 first and then the compressor 104 .

In the second embodiment, as shown in FIG. 6 , the dashed arrow in FIG. 6 shows the air circulation path, and there is one cross-flow fan 106 , which is arranged at the second bottom opening 110 b , and driven by the cross-flow fan 106 , The ambient air around the first bottom opening 110a enters into the compressor room 180, passes through the condenser 105 and the compressor 104 in sequence, takes away the heat of the condenser 105 and the compressor 104, and then flows out of the compressor room 180 from the cross-flow fan 106, and also flows out of the compressor room 180. That is, it flows below the bottom wall of the box (the space between the bottom wall of the box and the supporting surface of the refrigerator 100 ), and flows forward to the surrounding environment, thereby forming a circulation of heat dissipation air, ensuring the heat dissipation effect of the compressor cabin 180 .

In the third embodiment, as shown in FIG. 7 , one cross-flow fan 106 is provided between the first bottom opening 110a and the second bottom opening 110b, that is, the first bottom opening 110a, the cross-flow fan 106 and the second bottom opening 110b are laterally distributed in sequence, and the cross-flow fan 106 is configured to suck in ambient air from the first bottom opening 110a and the second bottom opening 110b, so as to promote the ambient air to pass through the condenser 105, the compressor 104, and then from the box body. The bottom wall flows forward into the surrounding environment. That is to say: driven by the cross-flow fan 106, the ambient air around the first bottom opening 110a enters the compressor chamber 180 from the first bottom opening 110a, flows through the condenser 105, and is then blown out from the cross-flow fan 106, The air flows below the bottom wall of the box (the space between the bottom wall of the box and the supporting surface of the refrigerator 100 ) to the surrounding environment; at the same time, the ambient air around the second bottom opening 110b enters the compressor compartment 180 from the second bottom opening 110b It flows through the compressor 104, and then blows out from the cross-flow fan 106, and flows to the lower part of the bottom wall of the box (the space between the bottom wall of the box and the supporting surface of the refrigerator 100) to the surrounding environment.

In some embodiments, side ventilation holes 119 a are formed on both lateral side walls of the compressor cabin 180 , and the ambient air around the side ventilation holes 119 a is driven into the compressor cabin 180 by the drive of the cross-flow fan 106 .

As shown in FIG. 1 and FIG. 2 , the outer casing 110 includes two lateral side panels 111 of the box body. The two side panels of the box body 111 extend vertically to form two side walls of the refrigerator 100. The two side panels of the box body 111 A side opening 111 a communicating with the corresponding side ventilation holes 119 a is respectively formed, so that ambient air on both sides of the refrigerator 100 can also enter the compressor compartment 180 .

In some embodiments, a section of the rear wall of the compressor compartment 180 corresponding to the compressor 104 is formed with a first rear ventilation hole 116a, and a section corresponding to the condenser 105 is formed with a second rear ventilation hole 116b. When the refrigerator 100 is used as a In the non-embedded use, the rear of the refrigerator 100 has a certain air circulation space. Under the action of the cross-flow fan 106, the compressor compartment 180 communicates with the air flow through the second rear ventilation hole 116b and/or the first rear ventilation hole 116a.

The vent 119a draws in ambient air and forces the ambient air through the condenser 105, the compressor 104, and then forwards from below the bottom wall of the case into the surrounding environment. That is to say: driven by the cross-flow fan 106 located at the first bottom opening 110a, the ambient air around the side ventilation hole 119a adjacent to the first bottom opening 110a enters the compressor chamber 180 from the side ventilation hole 119a, and flows through the side ventilation hole 119a. After the condenser 105, it enters the cross-flow fan 106, and flows forward from the bottom wall of the box to the surrounding environment; driven by the cross-flow fan 106 located at the second bottom opening 110b, it is close to the second bottom opening The ambient air around the side ventilation hole 119a of 110b enters the compressor room 180 from the side ventilation hole 119a, flows through the compressor 104, enters the cross-flow fan 106, and flows forward from the bottom wall of the box to the surrounding environment middle.
