[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The current refrigerator needs to rely on the refrigeration system to continuously release the heat in the compressor compartment to the environment in order to maintain a low temperature for a long time. The condenser is the main component for heat exchange between the compressor compartment and the external environment. The heat exchange efficiency will directly affect the refrigeration effect of the refrigerator's refrigeration system. In existing refrigerators, the condenser is usually installed in the compressor compartment. Compared with the back-mounted condenser, this condenser installation method is more space-saving. However, since the space in the compressor compartment is relatively closed and narrow, it is not conducive to the natural flow of air and the heat dissipation is slow, resulting in low heat exchange efficiency of the condenser. Therefore, the present invention proposes the following embodiments to solve the above technical problems.

[0032] Embodiment 1:

[0033] like Figure 1-Figure 4 The compressor compartment heat dissipation structure includes: a compartment 1, wherein an air inlet 101 and an air outlet 102 are provided at the bottom of the compartment 1; a compressor 2, wherein the compressor 2 is arranged in the compartment 1; a condenser 3, wherein the condenser 3 is arranged in the compartment 1 and close to the air inlet 101; and a fan 4, wherein the fan 4 is arranged in the compartment 1 and is located between the air inlet 101 and the air outlet 102, wherein the air inlet side of the fan 4 faces the condenser 3, and the air outlet side of the fan 4 faces the air outlet 102.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the compressor bin heat dissipation structure includes a bin 1, a compressor 2, a condenser 3 and a fan 4; wherein, the other sides of the bin 1 except the bottom side are sealed, and the bottom side of the bin 1 is provided with an air inlet 101 and an air outlet 102, the air inlet 101 is arranged at the right end of the bottom side of the bin 1, and the air outlet 102 is arranged at the left end of the bottom side of the bin 1, the compressor 2 is arranged on the left side of the fan 4 and located at the left part of the inside of the bin 1, so as to free up the space in the middle and right parts of the bin 1 for installing the fan 4 and condenser 3 and other components, the fan 4 is fixed in the middle part of the bottom side of the bin 1, and is located between the air inlet 101 and the air outlet 102, the right side of the fan 4 is the air inlet side, and the left side of the fan 4 is the air outlet side. The condenser 3 is arranged on the right side of the fan 4. Furthermore, the condenser 3 is close to the right side of the fan 4 housing. The closer the condenser 3 is to the air inlet side of the fan 4, the faster the fan 4 discharges the hot air near the condenser 3. In this embodiment, the air flow route is as follows: when the fan 4 is started, the outside air flows into the right end of the machine chamber 1 from the bottom air inlet 101 of the machine chamber 1, and under the action of the fan 4, the air at the right end of the machine chamber 1 is sucked into the left end of the machine chamber 1 by the fan 4. Under the action of the fan 4, the air in the left end of the machine chamber 1 flows downward from the machine chamber 1 to the outside through the exhaust port 102, and this cycle continues, thereby achieving the effect of accelerating the heat exchange of the condenser 3. In the present invention, by arranging the fan 4 between the air inlet 101 and the air outlet 102, the circulation flow of the air in the machine compartment 1 and the outside air can be accelerated, and the condenser 3 is arranged on the air inlet side of the fan 4. When the condenser 3 and the fan 4 work at the same time, the heat emitted by the condenser 3 will heat up the surrounding air, and the air inlet side of the fan 4 will absorb the hot air and discharge it toward the exhaust port, so that the hot air is discharged from the machine compartment 1, thereby accelerating the heat exchange efficiency of the condenser 3, thereby improving the refrigeration effect of the refrigerator.

[0035] As a further solution, the machine room 1 includes a room cover 5, a side panel 6 and a bottom plate 7, the two ends of the bottom plate 7 are respectively connected to the bottom of both sides of the room cover 5, the side panel 6 is arranged on the opening side of the room cover 5, the compressor 2, the condenser 3 and the fan 4 are all arranged on the bottom, and there is a gap between the bottom of the side panel 6 and the bottom plate 7 to form the air inlet 101 and the air outlet 102. Specifically, the front side and the bottom side of the bin cover 5 are open, the bottom plate 7 is arranged on the bottom side of the bin cover 5, the left and right ends of the bottom plate 7 are respectively fixedly connected to the bottom of the left and right ends of the bin cover 5, and the bottom plate 7 does not cover the bottom side of the bin cover 5, leaving a gap, the side plate 6 is arranged on the front side of the bin cover 5 and covers the front side of the bin cover 5, but there is a gap between the bottom of the side plate 6 and the side of the bottom plate 7, that is, there is a gap between the bottom of the side plate 6 and the bottom plate 7 to form the air inlet 101 and the air outlet 102, and at the same time, there is also a gap between the bottom plate 7 and the rear side of the bin cover 5 to speed up the circulation of air between the inside of the machine compartment 1 and the outside, thereby improving the heat dissipation speed in the machine compartment 1.

[0036] like Figure 3 As shown, as a further solution, the compressor compartment heat dissipation structure further includes a water receiving pan 8, which is arranged on the bottom plate 7 and is used to collect water discharged by the evaporator during defrosting. Further, the water receiving pan 8 is detachably mounted on the top side of the bottom plate 7, for example, it can be fixedly connected to the bottom plate 7 by bolts, or can be detachably mounted on the bottom plate 7 by fixing methods such as gluing.

[0037] In this embodiment, the compressor compartment heat dissipation structure further includes a bracket 9, which is arranged on the water receiving tray 8, and the condenser 3 and the fan 4 are respectively arranged on both sides of the bracket 9. Specifically, the bracket 9 is in a four-frame shape, the bracket 9 is installed on the top side of the water receiving tray 8, and the two ends of the bottom side of the bracket 9 are respectively fixedly connected to the top of the two sides of the water receiving tray 8, and the two can be fixed to each other by welding, or fixedly connected by screws, the fan 4 and the condenser 3 are simultaneously installed on the bracket 9, the fan 4 is located on the left side of the bracket 9, and the fan 4 is fixedly connected to the bracket 9 by screws, the condenser 3 is located on the right side of the bracket 9, and the condenser 3 is fixedly connected to the bracket 9 by screws, when the fan 4 is started, because the temperature of the water discharged during the defrosting of the evaporator is usually low, and under the action of the fan 4, the air above the water receiving tray 8 will be mixed with a certain amount of moisture with a low temperature, which has a certain cooling effect on the hot air near the condenser 3. At the same time, the fan 4 and the condenser 3 are integrated on the bracket 9, so that the integration consisting of the fan 4, the condenser 3 and the bracket 9 can be easily assembled and disassembled on the water receiving tray 8. Specifically, since the space in the machine room 1 is relatively small, it is not very convenient to repair the parts in the machine room 1, and it is inconvenient for maintenance personnel to perform tedious operations in the machine room with both hands. Therefore, when repairing the fan 4, condenser 3 and the bracket 9, the bracket 9 can be directly disassembled from the water receiving tray 8, and then the integration consisting of the fan 4, condenser 3 and bracket 9 is taken out of the machine room 1, and finally the integration consisting of the fan 4, condenser 3 and bracket 9 is disassembled in an open place, and the fan 4, condenser 3 and bracket 9 are repaired individually. After the repair, the fan 4, condenser 3 and bracket 9 are reassembled in an open place, and after assembly, the integration consisting of the fan 4, condenser 3 and bracket 9 is placed in the machine room 1, and the bottom edge of the bracket 9 is fixedly connected to the top of the water receiving tray 8 again.

The sealing frame 10 is detachably connected to the bracket, for example, by screws; the top side of the sealing frame 10 abuts against the top side in the machine chamber 1, the front side of the sealing frame 10 abuts against the inner side of the side plate 6 to seal the connection between the sealing frame 10 and the side plate 6, the back side of the sealing frame 10 abuts against the back side in the machine chamber 1 to seal the connection between the sealing frame 10 and the back side of the machine chamber 1, and the sealing frame 10 prevents air from flowing through the top side, front side and back side of the machine chamber 1, and prevents the hot air discharged to the left end of the machine chamber 1 from flowing back to the right end of the machine chamber 1, thereby further improving the heat dissipation effect.

At the same time, after the water receiving pan 8 is provided with the widening portion 801, the volume space can be further increased to increase the water capacity.

[0040] In this embodiment, a hook 802 is provided on the side where the water receiving tray 8 abuts against the side panel 6, and a groove 601 is provided on the bottom side of the side panel 6. The hook 802 is arranged in the groove 601 and supports the side panel 6. Specifically, two hooks 802 are provided on the side where the water receiving tray 8 abuts against the side panel 6, and two corresponding grooves are provided on the bottom side of the side panel 6. The hooks correspond to and are engaged with the grooves 601 one by one, and the bottom side of the side panel 6 is embedded in the hooks 802. A plurality of hooks 802 can be provided, and they only need to be arranged in a horizontal row and a plurality of corresponding grooves 601 are provided on the bottom side of the side panel. The four corners of the side panel 6 are respectively connected with the four corner screws on the front side of the bin cover 5, and the bottom side of the side panel 6 is supported by the hooks 802, which reduces the pressure on the screws, thereby enhancing the stability of the side panel 6.
