[0002] The condenser is an important component of the refrigerator refrigeration system, used to dissipate heat from the refrigerant circulating in the refrigeration system.

[0003] Currently, existing refrigerators typically use air cooling to dissipate heat from the condenser, using a condenser fan to release the heat from the condenser into the surrounding environment. However, this air cooling requires sufficient space around the refrigerator to allow for the circulation of cooling air. Furthermore, the activation of the condenser fan generates a certain amount of noise and has a heating effect on the surrounding environment. Utility Model Content

[0004] In view of this, it is necessary to provide a water cooling system and a refrigerator for solving the above technical problems.

[0005] A water cooling and heat dissipation system is used for cooling a condenser of a refrigerator with water; the water cooling and heat dissipation system comprises:

[0007] A water supply component is communicated with the water inlet. The water supply component is arranged above the water inlet in a vertical direction, and water discharged by the water supply component can flow toward the water inlet under the action of gravity.

[0008] It can be understood that immersing the condenser in the water in the condensing water tank and realizing water cooling of the condenser can solve the related problems caused by air cooling; in this process, the water discharged by the water supply component can flow into the condensing water tank under the action of gravity, so that the condensing water tank can realize unpowered water intake, which has the effect of reducing energy consumption and further reducing noise.

[0009] In one embodiment, the water supply assembly includes a defrost water receiving tray, the defrost water receiving tray is connected to and communicated with a first drain pipe, and an end of the first drain pipe away from the defrost water receiving tray is communicated with the water inlet;

[0010] The defrost water receiving tray is used to receive the defrost water generated when the evaporator is heated.

[0011] It is understandable that using defrost water to supply water to the condensation water tank and realizing the reuse of the defrost water in the refrigerator can, on the one hand, avoid the generation of odor and breeding of bacteria due to long-term moisture in the defrost water tray, and on the other hand, it can also utilize the low temperature of the defrost water to further improve the heat dissipation effect of the condenser in the condensation water tank during water cooling.

[0012] In one embodiment, the water supply assembly includes a water tank, the water tank is connected to and communicated with a second drain pipe, and an end of the second drain pipe away from the water tank is communicated with the water inlet;

[0013] Wherein, a first flow valve is provided on the second drainage pipe, and the first flow valve is used to control the on / off of the second drainage pipe.

[0014] It is understandable that the first flow valve is used to control the water outlet tank to drain water into the condensing water tank, which can ensure that there is enough water in the condensing water tank to immerse the condenser.

[0015] In one embodiment, a third drain pipe is connected to and communicated with the water tank, and a first communication port of the third drain pipe communicating with the water tank is arranged vertically above a second communication port of the second drain pipe communicating with the water tank;

[0016] Wherein, the water storage tank is used to receive domestic wastewater.

[0017] It can be understood that, through the above-mentioned structural arrangement, the water-cooling heat dissipation system can use domestic wastewater to dissipate heat from the condenser, which can save water resources.

[0018] In one embodiment, a first temperature probe is provided in the water storage tank, and the first temperature probe is used to detect the temperature of the domestic wastewater in the water storage tank and generate a first feedback signal;

[0019] The first flow valve can control the on / off of the second drain pipe according to the first feedback signal.

[0020] It can be understood that the first temperature probe is used to detect the temperature signal of the domestic wastewater in the water tank to control the on / off of the first flow valve, and to control whether the water tank discharges the domestic wastewater into the condensation water tank. This can ensure that the domestic wastewater discharged from the water tank to the condensation water tank can meet the use requirements of the condenser heat dissipation.

[0021] In one embodiment, the condensed water tank is connected to and communicated with a fourth drain pipe, and the fourth drain pipe is communicated with the water outlet;

[0022] Wherein, the condensation water tank is also connected to and communicated with an overflow pipe, and the overflow pipe is communicated with the fourth drain pipe.

[0023] It can be understood that the overflow pipe and the fourth drain pipe enable the condensate water tank to achieve overflow drainage.

[0024] In one embodiment, a second flow valve is provided on the condensate water tank, and the second flow valve is provided between the third connecting port connecting the fourth drain pipe and the overflow pipe and the water outlet, for controlling the on / off of the fourth drain pipe.

[0025] It can be understood that, through the setting of the above-mentioned second flow valve, the water cooling system can use the second flow valve to control the drainage of the condensation water tank when it is working. In this process, the overflow drainage of the condensation water tank is not affected.

[0026] In one embodiment, a second temperature probe is provided on the condensing water tank. The second temperature probe is provided in the area where the condenser is located in the condensing water tank, and is used to detect the temperature of water in the condensing water tank.

[0028] In one embodiment, a liquid level sensor is provided on the condensation water tank, and the liquid level sensor is used to detect the liquid level of water in the condensation water tank and generate a second feedback signal.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] The water cooling and heat dissipation system 100 claimed in this application is used for cooling and dissipating the heat of the condenser 201 of the refrigerator. Here, the condenser 201 is a component of the refrigeration system 200 of the refrigerator.

[0041] like Figure 1 As shown, a water-cooling heat dissipation system 100 provided in one embodiment of the present application includes a condenser water tank 10 and a water supply assembly 20. The condenser water tank 10 is used to accommodate a condenser 201. The condenser water tank 10 has a water inlet 11 and a water outlet 12. The water inlet 11 is located above the condenser water tank 10 and is used to add water to the condenser water tank 10. The water outlet 12 is used to drain the condenser water tank 10. The water supply assembly 20 is connected to the water inlet 11 and is arranged vertically above the water inlet 11. In addition, water discharged from the water supply assembly 20 can flow toward the water inlet 11 under the action of gravity. In other words, the water-cooling heat dissipation system 100 can dissipate heat from the condenser 201 by water cooling, which can solve the problems associated with air cooling. During this process, the water discharged from the water supply assembly 20 can flow into the condenser water tank 10 under the action of gravity, allowing the condenser water tank 10 to achieve unpowered water filling, thereby reducing energy consumption and further reducing noise.

[0042] It should be noted that the refrigeration system 200 of the refrigerator of the present application also includes a compressor 202, an evaporator 203, a drying filter 204 and a return air pipe assembly 205, and the compressor 202, the condenser 201, the drying filter 204 and the evaporator 203 are circulated and connected through the return air pipe assembly 205.

[0043] like Figure 2 As shown, the condensate tank 10 is connected to and communicates with a fourth drain pipe 13, which is connected to the water outlet 12, allowing the condensate tank 10 to drain outward through the fourth drain pipe 13. Specifically, the water in the condensate tank 10 can be directly discharged to the sewer through the fourth drain pipe 13. Here, the condensate tank 10 is also connected to and communicates with an overflow pipe 14, which is connected to the fourth drain pipe 13, allowing the condensate tank 10 to overflow and drain through the overflow pipe 14, thereby preventing the condensate tank 10 from overflowing due to excessive water.

[0044] like Figure 2As shown, the condensate tank 10 is equipped with a second flow valve 15. This second flow valve 15 is located between the third communication port 103, which connects the fourth drain pipe 13 and the overflow pipe 14, and the water outlet 12. This valve is used to control the flow of water through the fourth drain pipe 13. In other words, the condensate tank 10 can use the second flow valve 15 to control drainage. During this process, drainage from the condensate tank 10 through the fourth drain pipe 13 does not affect the overflow of the overflow pipe 14. The second flow valve 15 can be configured as a manual shut-off valve or a solenoid valve.

[0045] like Figure 2 As shown, the condensing water tank 10 is provided with a second temperature probe 16. The second temperature probe 16 is arranged in the area where the condenser 201 is located in the condensing water tank 10 and is used to detect the temperature of the water in the condensing water tank 10. This allows for real-time monitoring of the temperature of the water in the condensing water tank 10, providing a basis for using the water in the condensing water tank 10 to dissipate heat in the condenser 201, thereby ensuring that the water in the condensing water tank 10 can be water-cooled and dissipated by the condenser 201.

[0046] like Figure 2 As shown, the condensate tank 10 is provided with a liquid level sensor 17, which is used to detect the liquid level of the water in the condensate tank 10 and generate a second feedback signal. The condensate tank 10 can detect the liquid level of the water in the condensate tank 10 through the liquid level sensor 17, providing a basis for the water supply component 20 to add water to the condensate tank 10.

[0047] As preferably, Figure 2 As shown, the liquid level sensor 17 includes a first liquid level sensor 171 and a second liquid level sensor 172. The first liquid level sensor 171 is used to detect the liquid level of the water in the condensing water tank 10 when it submerges the condenser 201; the second liquid level sensor 172 is used to detect a low liquid level of the water in the condensing water tank 10. Here, the second liquid level sensor 172 is arranged at the bottom of the condenser 201 in the condensing water tank 10. At this time, the water in the condensing water tank 10 cannot cool the condenser 201 in the condensing water tank 10.

[0048] like Figure 1 As shown, the water supply assembly 20 includes a defrost water receiving pan 21, which is connected to and communicates with a first drain pipe 211. The end of the first drain pipe 211, which is away from the defrost water receiving pan 21, is communicated with the water inlet 11. Here, the defrost water receiving pan 21 is used to receive defrost water generated by heating the evaporator 203. Accordingly, the refrigerator is provided with a heating pipe 2031 in the area where the evaporator 203 is located.

[0049] It can be understood that defrost water is used to supply water to the condensation water tank 10 and to reuse the defrost water in the refrigerator. On the one hand, this can avoid the generation of odor and breeding of bacteria due to long-term moisture in the defrost water receiving tray 21. On the other hand, the low temperature of the defrost water can be utilized to further improve the heat dissipation effect of the condenser 201 in the condensation water tank 10 during water cooling.

[0050] like Figure 1 As shown, the water supply assembly 20 includes a water tank 22, to which a second drain pipe 221 is connected and communicated. The end of the second drain pipe 221, remote from the water tank 22, is communicated with the water inlet 11. This allows the water-cooling and heat dissipation system 100 to supply water to the condenser water tank 10 from the water tank 22, thereby ensuring that there is sufficient water in the condenser water tank 10 to submerge the condenser 201. A first flow valve 2211 is provided on the second drain pipe 221. The first flow valve 2211 is used to control the on / off state of the second drain pipe 221. Specifically, the first flow valve 2211 is configured as a solenoid valve. The structural characteristics of the solenoid valve can automatically control the on / off state of the second drain pipe 221.

[0051] like Figure 1 As shown, the water tank 22 is connected to and communicates with a third drain pipe 222. The third drain pipe 222 is connected to the first communication port 101 of the water tank 22 and is located vertically above the second communication port 102 of the second drain pipe 221. This allows the water-cooling heat dissipation system 100 to use domestic wastewater to dissipate heat from the condenser 201. During this process, the water tank 22 can overflow and drain through the third drain pipe 222. This ensures that the water tank 22 has sufficient domestic wastewater to discharge into the condensing water tank 10, thereby saving water resources. Here, the water tank 22 is used to receive domestic wastewater, and the third drain pipe 222 can discharge the domestic wastewater into the sewer.

[0052] It should be noted that the condensing water tank 10 of this application is located at the bottom of the refrigerator, at a height of approximately 20 cm. The water storage tank 22 is approximately 30 cm high and 55 cm above the ground. The bottom of the water storage tank 22 is higher than the condensing water tank 10, and the total height of the water storage tank 22 from the ground is no higher than 55 cm. This facilitates the collection of domestic wastewater by the water storage tank 22. Here, the water storage tank 22 only receives cold water from domestic water for use by the condensing water tank 10. A filter 223 is installed at the inlet of the water storage tank 22 to filter out impurities in the water collected by the filtered water storage tank 22.

[0053] like Figure 1As shown, a first temperature probe 224 is provided in the water tank 22, and the first temperature probe is used to detect the temperature of the domestic wastewater in the water tank 22 and generate a first feedback signal; wherein, the first flow valve 2211 can control the on / off of the second drain pipe 221 according to the first feedback signal, that is, it realizes the control of whether the water tank 22 discharges the domestic wastewater into the condensation water tank 10, so as to ensure that the domestic wastewater discharged from the water tank 22 to the condensation water tank 10 can meet the use requirements of the heat dissipation of the condenser 201.

[0054] As can be seen from the above, when the water cooling and heat dissipation system 100 of the present application is working, it is determined that water needs to be added to the condensing water tank 10 using the water supply component 20 based on the liquid level detection of the water in the condensing water tank 10 by the first liquid level sensor 171 and the second liquid level sensor 172. During this process, when the temperature of the water in the condensing water tank 10 detected by the second temperature probe 16 exceeds the temperature of the domestic wastewater in the water storage tank 22 monitored by the first temperature probe 224 by 10°, the second flow valve 15 on the fourth drain pipe 13 is opened to drain the water with higher temperature in the condensing water tank 10, and then the first flow valve 2211 is opened to add water with lower temperature into the condensing water tank 10 using the water storage tank 22.

[0055] In addition, the present application also provides a refrigerator, comprising the water cooling and heat dissipation system 100 described above.

[0056] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
