[0001] This application claims priority to Chinese application No. 202311870353.2, filed on December 29, 2023, the entire text of which is incorporated herein by reference. Technical Field

[0002] The present application relates to the field of refrigeration technology, and in particular to a refrigerator. Background Art

[0003] With the development of society and the improvement of people's living standards, refrigerators have become an indispensable household appliance in people's daily lives. During operation, refrigerators are prone to condensation, which can cause the refrigerator to become wet. Therefore, most refrigerators use dehumidification mechanisms to reduce or prevent condensation. However, traditional dehumidification mechanisms are not conducive to reducing refrigerator energy consumption. Summary of the Invention

[0004] The present application provides a refrigerator.

[0005] The technical solution is as follows.

[0006] According to a first aspect of an embodiment of the present application, a refrigerator is provided, comprising a cabinet assembly, a compressor, a condenser, a control valve assembly, a dew removal assembly, an expansion valve, an evaporator, and a control assembly. The cabinet assembly includes a freezer compartment, the freezer compartment including a door frame, and the door frame including a top. The compressor is disposed in the cabinet assembly, spaced apart from the door frame, and includes a first input and a first output. The condenser is disposed in the cabinet assembly, and includes a first output and a first input connected to the first output. The control valve assembly includes a second input connected to the first input and at least two second outputs. The dew removal assembly includes a first dew removal pipe and a second dew removal pipe, one end of the first dew removal pipe being connected to one of the second outputs. The first dew removal pipe includes a first tube extending along the length of the top, and one end of the second dew removal pipe being connected to the other second output. The second dew removal pipe includes an annular tube disposed around the door frame. The expansion valve includes a second input and a second output, the second input being connected to the other end of the first dew removal pipe and the other end of the second dew removal pipe, respectively. The evaporator is disposed within the housing assembly and includes a third input terminal and a third output terminal connected to the third input terminal, wherein the third input terminal is connected to the second output terminal. The control assembly is in communication with the compressor and the control valve assembly. When the humidity of the environment in which the refrigerator is located is less than or equal to a first threshold, the control assembly controls the control valve assembly to connect the first dew removal pipe to the first input terminal and close the second dew removal pipe to the first input terminal. When the humidity of the environment in which the refrigerator is located is greater than the first threshold but less than or equal to a second threshold, the control assembly controls the control valve assembly to connect the second dew removal pipe to the first input terminal and close the first dew removal pipe to the first input terminal.

[0007] The technical solutions provided by the embodiments of the present application include at least the following beneficial effects.

[0008] The refrigerator is provided with a first de-condensing pipe and a second de-condensing pipe, and the first tube body extends along the length direction of the top, and the annular tube body is arranged around the door frame. It is convenient for the control component to control the first de-condensing pipe or the second de-condensing pipe to be turned on according to different humidity to perform de-condensing. Specifically, when the humidity of the environment where the refrigerator is located is less than or equal to the first threshold value, the control valve assembly is controlled by the control component so that the second output end connected to the first de-condensing pipe is connected to the second input end, while the other second output ends are not connected to the second input end, and then the first de-condensing pipe is connected to the first input end, and the second de-condensing pipe is closed to the first input end. At this time, the refrigerant output by the compressor enters the condenser and condenses, and then enters the first de-condensing pipe, and heats the top of the freezing chamber through the first tube body. In this process, de-condensing can be performed by using the first tube body with a small de-condensing heating area, which can reduce the heat load caused by de-condensing on the refrigerator, and thus reduce the energy consumption during the operation of the refrigerator. When the humidity of the environment in which the refrigerator is located is greater than the first threshold but less than or equal to the second threshold, the control valve assembly is controlled by the control assembly so that the second output end connected to the second dew-removing pipe is connected to the second input end, while the other second output ends are not connected to the second input end. As a result, the second dew-removing pipe is connected to the first input end, and the first dew-removing pipe is closed to the first input end. At this time, the risk of condensation in the refrigerator increases. The refrigerant output by the compressor condenses in the condenser and then enters the second dew-removing pipe. The annular pipe body increases the heating area and heats the door frame of the freezer compartment (including its top space), thereby effectively preventing condensation near the freezer compartment. In this way, the dew-removing energy consumption of the refrigerator is low, which helps to reduce the energy consumption of the refrigerator.

[0047] Refrigerators, as refrigeration appliances, play a vital role in people's lives and bring numerous conveniences. However, with the current wide variety of refrigerators available, consumers are overwhelmed with choices. Winning consumer favor and enhancing product competitiveness are becoming increasingly important. Among refrigerators with similar functions or performance, the lower the energy consumption, the more attractive they are to consumers. Therefore, reducing refrigerator energy consumption has become a growing concern for refrigerator manufacturers.

[0048] Currently, condensation is easily generated during the operation of refrigerators, which can wet or dirty the refrigerator, hindering the cleanliness of the refrigerator operating environment. Therefore, most refrigerators use dehumidification structures to reduce or avoid condensation in the refrigerator.

[0049] Some refrigerators utilize dehumidification pipes in both the refrigerator and freezer compartments to reduce or prevent condensation. However, these pipes generate a significant heat load around the freezer compartment during operation, significantly increasing power consumption and hindering energy efficiency.

[0050] Based on this, the present application provides a refrigerator that optimizes the dew removal structure so that the dew removal energy consumption of the refrigerator is low, which is beneficial to reducing the energy consumption of the refrigerator.

[0051] In order to better understand the refrigerator of the present application, the following is further explained with reference to the accompanying drawings.

[0052] Figures 1 to 4 are schematic diagrams of the structures of refrigerators shown in some embodiments. Figure 1 is a schematic diagram of the structure of a refrigerator shown in one embodiment. Figure 2 is a schematic diagram of the dew removal principle of the refrigerator shown in Figure 1. Figure 3 is a schematic diagram of the operation of the refrigerator shown in Figure 2 with the first dew removal pipe open and the second dew removal pipe closed. Figure 4 is a schematic diagram of the operation of the refrigerator shown in Figure 2 with the second dew removal pipe open and the first dew removal pipe closed. Furthermore, as shown in Figure 1, the thickness direction of the refrigerator is the X-axis direction, the width direction of the refrigerator is the Y-axis direction, and the height direction of the refrigerator is the Z-axis direction.

[0053] As shown in Figures 1 to 4, in some embodiments, a refrigerator 10 is provided, comprising a cabinet assembly 100, a compressor 200, a condenser 300, a control valve assembly 400, a dew removal assembly 500, an expansion valve 600, an evaporator 700, and a control assembly 800. The cabinet assembly 100 includes a freezer compartment 110, which includes a door frame 111, which includes a top portion 101. The compressor 200 is disposed in the cabinet assembly 100, spaced apart from the door frame 111. The compressor 200 includes a first input portion 210 and a first output portion 220. The condenser 300 is disposed in the cabinet assembly 100. The condenser 300 includes a first output port 310 and a first input port 320 communicating with the first output port 220. The control valve assembly 400 includes a second input port 410 communicating with the first input port 320 and at least two second output ports 420. The dew removal assembly 500 includes a first dew removal pipe 510 and a second dew removal pipe 520. One end of the first dew removal pipe 510 is connected to one of the second output ends 420. The first dew removal pipe 510 includes a first tube 511 extending along the length of the top 101. One end of the second dew removal pipe 520 is connected to the other second output end 420. The second dew removal pipe 520 includes an annular tube 521 disposed around the door frame 111. The expansion valve 600 includes a second input portion 610 and a second output portion 620. The second input portion 610 is connected to the other end of the first dew removal pipe 510 and the other end of the second dew removal pipe 520, respectively. The evaporator 700 is disposed in the cabinet assembly 100 and includes a third input portion 710 and a third output portion 720 connected to the third input portion 710. The third input portion 710 is connected to the second output portion 620. The control assembly 800 is in communication with the compressor 200 and the control valve assembly 400. When the humidity of the environment in which the refrigerator 10 is located is less than or equal to a first threshold, the control assembly 800 controls the control valve assembly 400 to connect the first dew removal pipe 510 to the first input end 320 and close the second dew removal pipe 520 to the first input end 320. When the humidity of the environment in which the refrigerator 10 is located is greater than the first threshold but less than or equal to a second threshold, the control assembly 800 controls the control valve assembly 400 to connect the second dew removal pipe 520 to the first input end 320 and close the first dew removal pipe 510 to the first input end 320.

[0054] During operation of the refrigerator 10, the compressor 200 operates, delivering high-temperature, high-pressure gaseous refrigerant to the first input port 320 via the first output port 220. This refrigerant is condensed into medium-temperature, high-pressure gaseous refrigerant by the condenser 300 and then delivered to the dew-removing pipe from the first output port 310. The dew-removing pipe heats the air near the dew-removing pipe, thereby reducing the risk of condensation. During this process, the refrigerant cools further before entering the expansion valve 600. The throttling effect of the expansion valve 600 further reduces the refrigerant's pressure and temperature, and liquid refrigerant flows out of the second output port. From the second output port, the liquid refrigerant flows into the evaporator 700, where it absorbs heat, transforming into a gaseous state. It then flows out of the third output port 720 and enters the compressor 200 through the first input port 210. This cycle continuously absorbs heat from the evaporator 700, lowering the temperature of the freezer compartment 110 and facilitating the freezing of food in the freezer compartment 110.

[0055] Furthermore, the refrigerator 10 is provided with a first de-condensation tube 510 and a second de-condensation tube 520, and the first tube body 511 extends along the length direction of the top 101, and the annular tube body 521 is arranged around the door frame 111. This facilitates the control component 800 to control the first de-condensation tube 510 or the second de-condensation tube 520 to be turned on according to different humidity levels to perform de-condensation. Specifically, when the humidity of the environment in which the refrigerator 10 is located is less than or equal to the first threshold value (as shown in FIG3 ), the control valve assembly 400 is controlled by the control component 800 so that the second output end 420 connected to the first de-condensation tube 510 is connected to the second input end 410, while the other second output ends 420 are not connected to the second input end 410, thereby connecting the first de-condensation tube to the first input end 320, and closing the second de-condensation tube 520 to the first input end 320. At this time, the refrigerant output by the compressor 200 enters the condenser 300, condenses, and then enters the first dew removal pipe 510, where it is used to heat the top 101 of the freezer compartment 110 (for example, to heat the center beam) through the first tube body 511. During this process, dew removal can be performed using the first tube body 511, which has a small dew removal heating area. This can reduce the heat load caused by dew removal on the refrigerator 10, thereby reducing the energy consumption during the operation of the refrigerator 10. When the humidity of the environment in which the refrigerator 10 is located is greater than the first threshold value but less than or equal to the second threshold value (as shown in Figure 4), the control valve assembly 400 is controlled by the control assembly 800, so that the second output end 420 connected to the second dew removal pipe 520 is connected to the second input end 410, while the other second output ends 420 are not connected to the second input end 410. As a result, the second dew removal pipe is connected to the first input end 320, and the first dew removal pipe 510 is closed to the first input end 320. At this point, the risk of condensation in refrigerator 10 increases. The refrigerant output by compressor 200 condenses in condenser 300 and then enters second dew removal pipe 520. The annular pipe 521 increases the heating area and heats door frame 111 of freezer compartment 110 (including the space at top 101 thereof), effectively preventing condensation near freezer compartment 110. Thus, by optimizing the dew removal structure, refrigerator 10 reduces dew removal energy consumption, thereby helping to reduce energy consumption of refrigerator 10.

[0056] From the above description, it can be seen that the refrigerator 10 provided by the present application can meet the dew removal requirements in different humidity environments. When the humidity of the environment in which the refrigerator 10 is located is low, the first dew removal pipe 510 is used for dew removal, which can reduce the heat load caused by dew removal on the refrigerator 10, thereby reducing the energy consumption during the operation of the refrigerator 10 and saving electricity. At the same time, it can also effectively avoid condensation near the top 101 of the freezing chamber 110 (for example, preventing condensation on the middle beam and the freezing door seal). When the humidity of the environment in which the refrigerator 10 is located is high, the second dew removal pipe 520 is used for dew removal, and the heat load caused by dew removal on the refrigerator 10 can be reduced by reasonably arranging the annular tube body 521 to heat the freezing chamber 110. Therefore, regardless of the working area or the season, the refrigerator 10 provided by the present application can reduce energy consumption while also having good dew removal performance.

[0057] It should be noted that "first tube 511 extends along the length of top 101" includes at least a portion of first tube 511 being directly mounted on top 101, or first tube 511 being indirectly mounted on top 101, so long as heating and dehumidifying top 101 is possible. Referring to FIG. 1 , along the Z-axis, top 101 is the upper frame of door frame 111, and the length of top 101 is the Y-axis.

[0058] In some embodiments, the length direction of the first tube 511 is arranged in the same direction as the length direction of the top 101 .

[0059] It should be noted that "the annular tube 521 is arranged around the door frame 111" includes the annular tube 521 being arranged to wrap the entire door frame 111, or the annular tube 521 being arranged to wrap a portion of the door frame 111. As shown in FIG1 , the compressor 200 and the door frame 111 are spaced apart in the box assembly 100 along the X-axis direction.

[0060] It should be noted that the value of the first threshold can be flexibly set to include but is not limited to 60%, 65%, 70%, 75%, etc. The value of the second threshold can be flexibly set to include but is not limited to 80%, 85%, 90%, 95%, etc.

[0061] Optionally, the first threshold is 75%, and the second threshold is 90%.

[0062] As shown in FIG5 , in some embodiments, when the humidity of the environment in which the refrigerator 10 is located is greater than a second threshold, the control assembly 800 controls the control valve assembly 400 to connect the first dew removal pipe 510 and the second dew removal pipe 520 to the first input end 320. In this way, even if the humidity of the operating environment of the refrigerator 10 is very high, the first dew removal pipe 510 and the second dew removal pipe 520 can work together to remove dew from the refrigerator 10.

[0063] Furthermore, in some embodiments, the refrigerator 10 further includes a humidity detection assembly (not shown) in communication with the control assembly 800. The humidity detection assembly is disposed in the cabinet assembly 100 and is configured to detect the humidity of the environment surrounding the refrigerator 10. This facilitates the control assembly 800 to detect the humidity of the environment surrounding the refrigerator 10 in real time based on the temperature detection assembly and promptly control the control valve assembly 400 to switch between the first dew removal pipe 510 and the second dew removal pipe 520, thereby reducing the energy consumption of the refrigerator 10 and the risk of condensation.

[0064] It should be noted that humidity detection components include but are not limited to telescopic hygrometers, dry-bulb and wet-bulb thermometers, dew point thermometers and resistance hygrometers.

[0065] As shown in FIG2 , in some embodiments, the refrigerator 10 further includes a flow regulating assembly 1100, and the other end of the first dew removing pipe 510 and the other end of the second dew removing pipe 520 are connected to the third input end 710 via the flow regulating assembly 1100. The flow regulating assembly 1100 is communicatively connected to the control assembly 800. When the ambient temperature of the refrigerator 10 is less than or equal to a third threshold, the flow regulating assembly 1100 outputs a first flow rate. When the ambient temperature of the refrigerator 10 is greater than the third threshold, the flow regulating assembly 1100 outputs a second flow rate greater than the first flow rate. Thus, the control assembly 800 is communicatively connected to the temperature detection assembly. When the ambient temperature of the refrigerator 10 is less than or equal to the third threshold, the external temperature is relatively low, and the energy required to maintain the freezing effect of the freezing chamber 110 is low. The first flow rate is output to the first dew removing pipe 510 and / or the second dew removing pipe 520 via the flow regulating assembly 1100. When the ambient temperature of refrigerator 10 is greater than the third threshold, the external temperature is relatively high. To maintain the freezing effect of freezing chamber 110, flow regulating assembly 1100 needs to output a second flow rate, which is greater than the first flow rate, to first dew removal pipe 510 and / or second dew removal pipe 520. The second flow rate is then delivered to evaporator 700 for rapid heat absorption and cooling. This can further reduce power consumption, improve energy efficiency, and ensure the freezing effect of refrigerator 10.

[0066] As shown in Figures 2 and 4, and in combination with Figure 11, in some embodiments, the flow regulating component 1100 includes a first capillary 1110 for outputting a first flow, a second capillary 1120 having a larger flow area than the first capillary 1110, and a first reversing valve 1130 communicated with the control component 800, one end of the first capillary 1110 and one end of the second capillary 1120 are respectively connected to the output end of the first reversing valve 1130, the other end of the first capillary 1110 and the other end of the second capillary 1120 are respectively connected to the third input end 710, and the input end of the first reversing valve 1130 is respectively connected to the other end of the first de-contamination pipe 510 and the other end of the second de-contamination pipe 520. When the ambient temperature of the refrigerator 10 is less than or equal to a third threshold, the third input end 710 communicates with the first de-condensation pipe 510 and / or the second de-condensation pipe 520 via the first capillary tube 1110. When the ambient temperature of the refrigerator 10 is greater than the third threshold, the third input end 710 communicates with the first de-condensation pipe 510 and / or the second de-condensation pipe 520 via the second capillary tube 1120. Thus, the control component 800 is in communication with the temperature detection component. When the ambient temperature of the refrigerator 10 is less than or equal to the third threshold, the external temperature of the refrigerator 10 is relatively low (e.g., less than or equal to 30 degrees Celsius), and the energy required to maintain the freezing effect of the freezing chamber 110 is relatively low. The first reversing valve 1130 operates, causing the third input end 710 to communicate with the first de-condensation pipe 510 and / or the second de-condensation pipe 520 via the first capillary tube 1110, thereby facilitating the output of the first flow rate to the first de-condensation pipe 510 and / or the second de-condensation pipe 520. When the ambient temperature of refrigerator 10 exceeds the third threshold, indicating a high external temperature (e.g., greater than 30°C), first reversing valve 1130 operates, connecting third input port 710 to first dew-removing pipe 510 and / or second dew-removing pipe 520 via second capillary tube 1120. This facilitates the output of a second flow rate, which is greater than the first flow rate, to first dew-removing pipe 510 and / or second dew-removing pipe 520. This flow rate is then delivered to evaporator 700 for rapid heat absorption and cooling, thereby ensuring the freezing effect of refrigerator 10. This further reduces power consumption, lowering the energy consumption of refrigerator 10 while improving energy efficiency. This simultaneously ensures the freezing effect of refrigerator 10 and reduces the risk of condensation.

[0067] In some embodiments, the refrigerator 10 further includes a temperature detection component (not shown) in communication with the control component 800. The temperature detection component is disposed in the housing component 100 and is configured to detect the ambient temperature of the refrigerator 10. This facilitates the control component 800 to detect the ambient temperature of the refrigerator 10 in real time based on the temperature detection component and promptly control the flow control component 1100 to output the first flow rate or the second flow rate, thereby reducing the energy consumption of the refrigerator 10 while minimizing the risk of condensation.

[0068] It should be noted that the temperature detection components include but are not limited to expansion temperature sensors, thermal resistance temperature sensors, thermoelectric temperature sensors, photoelectric pyrometers, radiation sensors, colorimetric thermometers, etc.

[0069] As shown in Figures 6 to 8, in some embodiments, the annular tube 521 is snap-fitted to the door frame 111. This facilitates fixing the annular tube 521 to the door frame 111, which helps improve assembly efficiency.

[0070] As shown in FIG8 , in some embodiments, the door frame 111 is provided with a first slot 102, and the annular tube 521 is inserted into the first slot 102. Thus, the annular tube 521 is inserted into the first slot 102 so that the annular tube 521 is embedded in the door frame 111, making full use of the space of the door frame 111 to accommodate the annular tube 521. The two fit tightly together, resulting in higher heat conduction efficiency and further reducing the energy consumption of the refrigerator 10.

[0071] As shown in FIG8 , in some embodiments, the door frame 111 is provided with a flange 103 , which is bent to form the first slot 102 . This facilitates implementation and reduces the number of assembly steps for the door frame 111 .

[0072] As shown in Figures 6 and 7, in some embodiments, the cabinet assembly 100 includes a base 130, a door frame 111 and a compressor 200 are spaced apart on the base 130, and the top 101 is positioned above the compressor 200 relative to the base 130. The first dew removal pipe 510 includes two second tubes 512, which are arranged at an acute angle to the base 130. The two second tubes 512 are spaced apart on either side of the freezing chamber 110 and are respectively connected to the two ends of the first tube 511. One of the second tubes 512 is connected to the second output end 420, and the other second tube 512 is connected to the second input portion. In this way, the two second tubes 512 are spaced apart on either side of the freezing chamber 110 to transport the refrigerant output from the second output end 420 to the first tube 511 through one of the second tubes 512, and the first tube 511 is used to heat the top 101 of the freezing chamber 110. The refrigerant passing through the first tube 511 is transported to the expansion valve 600 by the second tube 512. During this process, the second tube 512 is arranged at an acute angle to the base 130, transporting the refrigerant diagonally upward through the first tube 511 and diagonally downward to the expansion valve 600. This effectively reduces the refrigerant transmission path to the first tube 511, thereby reducing the heat load on the refrigerator 10 caused by dew removal, thereby reducing energy consumption during operation of the refrigerator 10.

[0073] 1 , the door frame 111 and the compressor 200 are disposed on the base 130 with a distance therebetween along the X-axis direction.

[0074] As shown in Figures 7 and 9, in some embodiments, the second dew removal pipe 520 further includes a delivery pipe 522 connected to one end of the annular pipe 521 and a return pipe 523 connected to the other end of the annular pipe 521. At least a portion of the delivery pipe 522 and at least a portion of the return pipe 523 are adjacent to each other and extend between the bottom of the freezing chamber 110 and the base 130. In this manner, the refrigerant output from the second output end 420 is delivered to the annular pipe 521 via the delivery pipe, and then the refrigerant passing through the first pipe 511 is delivered to the expansion valve 600 via the return pipe 523. In this process, at least a portion of the delivery pipe 522 and at least a portion of the return pipe 523 extend between the bottom of the freezing chamber 110 and the base 130, facilitating heat dissipation from the base 130, reducing the heat load on the refrigerator 10 caused by dew removal, and thereby lowering energy consumption during operation of the refrigerator 10.

[0075] During this process, at least part of the delivery pipe body 522 and at least part of the return pipe body 523 are close to each other, which is also beneficial to improving the degree to which the annular pipe body 521 wraps the door frame 111, reducing the heat load caused by dew removal on the refrigerator 10, and reducing the energy consumption of the refrigerator 10.

[0076] Further, as shown in FIG7 , in some embodiments, at least a portion of the annular tube body 521 is nested within the door frame 111. The door frame 111 is provided with a first notch 104 for accommodating the delivery tube body 522 and the return tube body 523. The base 130 is provided with a second notch 131 for accommodating the delivery tube body 522 and the return tube body 523. The second notch 131 is disposed opposite the first notch 104. In this manner, the delivery tube body 522 and the return tube body 523 respectively pass through the first notch 104 and the second notch 131 to communicate with the annular tube body 521, which facilitates implementation and helps reduce the difficulty of assembling the second dew removal pipe 520 and the door frame 111.

[0077] In combination with any of the above embodiments, as shown in Figures 6 and 8, in some embodiments, the cabinet assembly 100 further includes a crossbeam 120 fixed to the top 101. The crossbeam 120 includes a first clamping portion 121. The first clamping portion 121 is spaced apart from the top 101 along the height direction of the cabinet assembly 100, and the first tube 511 is disposed in the first clamping portion 121. In this way, the crossbeam 120 is fixed to the top 101, and the first tube 511 is disposed in the first clamping portion 121. The first tube 511 can be used to remove dew from the crossbeam 120 and the top 101. This increases the dew removal range of the first tube 511 while reducing the energy consumption of the refrigerator 10, further reducing the risk of condensation in the refrigerator 10.

[0078] Optionally, the crossbeam 120 is made of metal. This provides good thermal conductivity, facilitating heat transfer from the first tube 511 to the top 101 , thereby improving the efficiency of dehumidification from the crossbeam 120 and the top 101 using the first tube 511 . This can reduce the heat load on the refrigerator 10 caused by dehumidification, thereby lowering the energy consumption of the refrigerator 10.

[0079] As shown in FIG8 , in some embodiments, the first clamping portion 121 is provided with a second clamping groove 1211 , and the first tube 511 is inserted into the second clamping groove 1211 . This facilitates implementation and facilitates mounting the first tube 511 on the beam 120 .

[0080] Furthermore, as shown in FIG8 , in some embodiments, the crossbeam 120 further includes a third slot 1212 that snaps into engagement with the top 101. The top 101 and the inner sidewall of the third slot 1212 cooperate to form a latching hole 1213, and at least a portion of the annular tube 521 is disposed within the latching hole 1213. Thus, the third slot 1212 snaps into engagement with the top 101, securing the crossbeam 120 to the top 101. The annular tube 521 is disposed within the latching hole 1213, allowing dew removal from the crossbeam 120 and the top 101. This reduces the energy consumption of the refrigerator 10 while also increasing the dew removal range of the annular tube 521, further reducing the risk of condensation in the refrigerator 10.

[0081] As shown in Figures 6, 9, and 10, in some embodiments, the refrigerator 10 further includes a first air cooler 900, which is disposed in the cabinet assembly 100 and is used to dissipate heat from the condenser 300. Thus, the first air cooler 900 is used to actively dissipate heat from the condenser 300, thereby improving the refrigerant condensation efficiency of the condenser 300.

[0082] As shown in Figures 6, 9, and 11, in some embodiments, the refrigerator 10 further includes a drying assembly 1000 for drying the refrigerant. The other end of the first dew removal pipe 510 and the other end of the second dew removal pipe 520 are respectively connected to the second input portion through the drying assembly 1000. This facilitates gas-liquid separation of the refrigerant and protects the compressor 200.

[0083] Optionally, a specific implementation of the drying component 1000 includes a gas-liquid separator.
