[0002] In related technologies, refrigerator-built-in cold water production devices typically employ a design where the water storage container is placed within the refrigerator compartment. This device relies on the ambient temperature of the refrigerator compartment to cool the water in the container. However, this method has several inherent drawbacks: First, the cooling efficiency is limited by the temperature difference within the refrigerator compartment, resulting in a slow cold water production rate, making it difficult to meet users' immediate or continuous demand for cold water; second, the water stagnates in the refrigerator compartment for extended periods, making it susceptible to odors from other items within the compartment, and under certain conditions, there is a possibility of water quality deterioration, affecting the quality and safety of drinking water.

[0041] In related technologies, the cold water production equipment used in refrigerators puts water in a container and relies on the temperature of the refrigerator compartment for cooling. If the water stays in the refrigerator compartment for a long time, it will produce odors and deteriorate. In addition, the cold water production speed is slow and cannot meet the needs for continuous use.

[0042] This application provides a cold water production device and a refrigerator to solve the problems of low efficiency and safety in existing cold water production devices. The following will be described in conjunction with the accompanying drawings. Figure 1-5 Explanation (the arrows in the diagram indicate the direction of water or refrigerant flow).

[0043] The cold water production equipment provided in this application embodiment is referenced. Figure 1 and Figure 2 As shown, the system includes a cooling box 100 with a receiving cavity 101; a heat transfer medium 200 is disposed in the receiving cavity 101; a water pipe 300 is provided with an inlet 310 and an outlet 320, and the water pipe 300 is at least partially disposed in the receiving cavity 101 and exchanges heat with the heat transfer medium 200; a refrigeration system 400 includes an evaporator 410, which is disposed in the cooling box 100 and used to cool the heat transfer medium 200.

[0044] In this embodiment, the cooling box 100 is the main structure of the device and can be made of materials with certain strength and cold resistance (such as food-grade plastic, metal, etc.). Its interior is designed with one or more cavities 101 to accommodate the heat-conducting medium 200 and the water pipe 300. The heat-conducting medium 200 is filled within the cavities 101 of the cooling box 100. It can be a liquid (such as cooling oil, silicone oil, ethylene glycol aqueous solution, etc.) or a phase change material, or even a solid of a specific shape (such as thermally conductive gel), or it can be paraffin wax, thermally conductive silicone, alcohol, etc. On one hand, it closely contacts or wraps around the water pipe 300, enabling it to quickly absorb heat from the water in the water pipe 300; on the other hand, it exchanges heat with the evaporator pipe 410 of the refrigeration system 400.

[0045] Water pipe 300 serves as a channel for conveying water to be cooled and water that has already been cooled. It can be made of 304 stainless steel to ensure water quality safety. Water pipe 300 has a clearly defined inlet 310 (connecting to the ambient temperature water source to be cooled) and outlet 320 (outputting cooled water). At least a portion of it is housed within the receiving cavity 101 of the cooling box 100 and exchanges heat with the heat-conducting medium 200. This portion of water pipe 300 can be completely submerged in the heat-conducting medium 200 or tightly wrapped / fitted to the area filled with the heat-conducting medium 200.

[0046] The water to be cooled enters the water pipe 300 through the inlet 310. During the flow inside the water pipe 300, it exchanges heat with the surrounding high thermal conductivity medium 200 through the pipe wall, and the temperature drops rapidly. The cooled water then flows out from the outlet 320 for the user to use.

[0047] The refrigeration system 400 is the core component that provides cooling capacity, and its key component is the evaporator tube 410. The evaporator tube 410 is typically made of metal (such as copper tubing) and contains refrigerant. The evaporator tube 410 is mounted on the cooling box 100, and its specific location can be the area in closest contact with the heat transfer medium 200, for example, directly coiled around the wall of the receiving cavity 101, or immersed in the heat transfer medium 200.

[0048] After the cold water production equipment is started, the evaporator 410 cools the heat transfer medium 200. The low-temperature medium then cools the stainless steel water pipe 300 immersed in it, thereby lowering the water temperature inside the pipe. Because the water pipe 300 has a small volume and the medium temperature is uniform, the equipment can continuously and stably provide cold water, achieving a continuous supply.

[0049] Compared to existing technologies that rely on slow cooling from the air in the refrigerator compartment, this device efficiently transfers the cooling energy from the evaporator tube 410 to the water in the water pipe 300 via a heat transfer medium 200. This results in high heat exchange efficiency and a cooling rate far exceeding that of air cooling. The refrigeration system 400 can continuously and stably provide cooling, unaffected by other items inside the refrigerator or door opening. Therefore, the cold water production speed is greatly accelerated, enabling rapid response to user needs and supporting a continuous, large-volume supply of cold water, completely solving the problems of slow and discontinuous production speed in existing cold water production equipment.

[0050] The water pipe 300 and the water inside it are placed in a separate receiving cavity 101 of the cooling box 100, physically isolated from other food, beverages, etc. in the refrigerator compartment. This effectively prevents potential odor sources in the refrigerator from permeating into the water through the air, inhibits bacterial growth and water quality deterioration, and improves the safety of cold water for consumption.

[0051] It should be noted that the cooling box 100 in this embodiment can be used not only for cooling water, but also for cooling milk, soy milk or other beverages. This embodiment does not make any specific limitations on this.

[0052] In one alternative implementation, control Figure 1 and Figure 3 As shown, the cooling box 100 includes a box body 110 and a cover 120. The cover 120 covers the box body 110 and forms a receiving cavity 101 with the box body 110. The water pipe 300 is installed on the cover 120.

[0053] In this embodiment, the design of dividing the cooling box 100 into two parts, the box body 110 and the cover body 120, makes the entire cooling box 100 not a fully enclosed structure that is injection molded or processed as a whole, but a detachable and non-fully enclosed structure, which is convenient for manufacturing and processing.

[0054] The box body 110 and the cover 120 are assembled using a pre-designed connection method (such as snap-fit, thread, welding, etc.). During assembly, the cover 120, pre-installed with the water pipe 300, can be easily fitted onto the box body 110 to form a complete receiving cavity 101. This method simplifies the assembly process, reduces assembly difficulty and the complexity of required tools, and improves assembly efficiency and accuracy.

[0055] In one optional implementation, combined with Figure 1 , Figure 4 and Figure 5 As shown, the box body 110 includes an inner liner 111 and an outer liner 112 sleeved outside the inner liner 111. The inner liner 111 contains a heat-conducting medium 200, and the evaporation tube 410 is wound around the outer wall of the inner liner 111 along the height direction of the inner liner 111.

[0056] In this embodiment, the evaporator tube 410 is a key component of the refrigeration system 400, responsible for providing cooling and absorbing heat. In this embodiment, the evaporator tube 410 is not directly mounted on the outer shell of the cooling box 100, but is tightly wound around the outer wall of the inner liner 111 along its height. This means that the evaporator tube 410 forms direct, large-area contact with the outer wall of the inner liner 111. By being wound around the outer wall of the inner liner 111, the evaporator tube 410 can efficiently absorb heat from the inner liner 111, thereby rapidly cooling the inner liner 111 and its internal heat-conducting medium 200.

[0057] The evaporator tube 410 can cover the outer wall of the inner liner 111 more evenly, which helps to make the overall temperature distribution of the inner liner 111 more uniform, avoid local overheating or undercooling, and thus ensure the consistency of the temperature of the heat transfer medium 200, further improving the stability and effect of water cooling.

[0058] Optionally, after the evaporator tube 410 is coiled in place, it is fixed by welding. The main purpose of welding is to firmly fix the coiled evaporator tube 410 to the inner liner 111, so as to prevent it from shifting, loosening or even falling off due to vibration or external force during subsequent assembly, transportation, handling or even refrigerator operation, thereby enhancing the overall stability and durability of the cooling box 100.

[0059] In one alternative implementation, refer to Figure 1 and Figure 5As shown, the interior of the cover 120 is filled with a first insulation layer 113; in another optional embodiment, the gap between the inner liner 111 and the outer liner 112 is filled with a second insulation layer 114.

[0060] In this embodiment, by setting the first insulation layer 113 and the second insulation layer 114, the temperature of the heat-conducting medium 200 is more stable and fluctuates less. This allows the water in the water pipe 300 to be cooled to the target temperature more consistently, avoiding the situation where the cold water temperature fluctuates and thus improving the quality and consistency of the cold water obtained by the user.

[0061] In one alternative implementation, refer to Figure 1 As shown, the cover 120 is provided with a temperature sensing tube 130, and the measuring end of the temperature sensing tube 130 is set on the heat-conducting medium 200 for measuring the temperature of the heat-conducting medium 200.

[0062] Optionally, the temperature sensing tube 130 can also be pre-assembled with the cover 120 by welding. This provides a direct, accurate, and rapid means of temperature monitoring. This greatly improves the control precision and response speed of the cold water production system, thereby ensuring the stability and consistency of cold water quality.

[0063] In one optional implementation, combined with Figure 1 , Figure 2 and Figure 6 As shown, the refrigeration system 400 includes a compressor 420, a condenser 430, and an electromagnetic switching valve 440 connected in sequence. The outlet of the electromagnetic switching valve 440 is provided with a first branch 401 and a second branch 402 connected in parallel. The first branch 401 is connected to the evaporator pipe 410, and the outlet of the first branch 401 and the second branch 402 connected in parallel is provided with an evaporator 450. The evaporator 450 is used to refrigerate the refrigerator compartment or the freezer compartment of the refrigerator. The electromagnetic switching valve 440 is used to switch the conduction of either the first branch 401 or the second branch 402.

[0064] In this embodiment, after the compressor 420 starts, it first detects whether there is a need to produce chilled water. When a need for chilled water is detected, the control system sends a signal to the solenoid switching valve 440, causing it to open the first branch 401. At this time, the high-pressure liquid refrigerant from the condenser 430 flows to the evaporator tube 410 in the cooling box 100, where it absorbs heat and vaporizes, thereby efficiently cooling the heat transfer medium 200 and subsequently cooling the water in the water pipe 300, achieving rapid production of chilled water. Simultaneously, the path to the second branch 402 is blocked, and the refrigerator's regular cooling is temporarily weakened or stopped. Although the refrigerant from the first branch 401 flows back to the compressor 420 after passing through the evaporator 450, the evaporator 450 can perform cooling without being turned on.

[0065] When there is no need for chilled water, or when chilled water has been prepared (the electromagnetic switching valve 440 switches after the chilled water temperature sensor confirms that the temperature meets the standard), the control system sends a signal to the electromagnetic switching valve 440, causing it to open the second branch 402. At this time, the high-pressure liquid refrigerant flows directly to the refrigerator evaporator 450 through the second branch 402, where it absorbs heat and vaporizes inside the refrigerator, lowering the refrigerator's temperature and restoring its normal refrigeration function. The first branch 401 leading to the evaporator pipe 410 is then cut off.

[0066] The refrigeration system 400 structure in this embodiment, including an electromagnetic switching valve 440 and parallel branches, provides a flexible and relatively direct method for controlling the refrigerant flow. By switching the electromagnetic valve, the refrigeration capacity can be independently or preferentially allocated to the chilled water equipment or the refrigerator evaporator 450, achieving effective switching and balance between rapid chilled water preparation and conventional refrigerator refrigeration. This meets the user's demand for rapid chilled water while also taking into account the overall refrigeration effect of the refrigerator.

[0067] In one alternative implementation, refer to Figure 2 As shown, at least one of an anti-condensation pipe 460 and a filter 470 is also provided between the condenser 430 and the solenoid switching valve 440.

[0068] Understandably, when the refrigerator is running, if the temperature of the refrigerator's outer casing and door seals is lower than the dew point temperature of the ambient air, water vapor in the air will condense into water droplets (condensation). Installing the anti-condensation pipe 460 can prevent this condensation problem. Furthermore, installing the filter 470 can prevent blockages in the refrigeration system 400 pipes, improving the overall reliability of the equipment.

[0069] In one alternative implementation, refer to Figure 2 As shown, the outlet of the evaporator 450 is provided with a return gas heat exchange section 451, which is configured to exchange heat with the first branch 401 and the second branch 402.

[0070] Understandably, the return gas heat exchange section 451 can cool the capillary sections of the first branch 401 and the second branch 402, increasing the subcooling and resulting in a lower evaporation temperature, thus enhancing the cooling effect. On the other hand, the capillary sections of the first branch 401 and the second branch 402 absorb the cold energy from the return gas heat exchange section 451, raising the temperature of the return gas heat exchange section 451. This helps to raise the temperature of the tube wall of the return gas heat exchange section 451, making it less likely to fall below the dew point temperature of the ambient air, thereby effectively preventing external condensation.

[0071] It is understood that in the above embodiments, the length and coil shape of the evaporator tube 410, the position of the temperature sensing tube 130, the length and coil shape of the stainless steel water pipe 300, etc. can all be adjusted as needed. The water inlet method of the water pipe 300 can be an external water pipe 300 or water can be supplied through an inlet valve. This embodiment does not make specific limitations on this.

[0072] The cold water production equipment provided in this application includes a cooling box 100, a heat-conducting medium 200, a water pipe 300, and a refrigeration system 400. The cooling box 100 forms a receiving cavity 101, and the heat-conducting medium 200 is disposed within the receiving cavity 101. The water pipe 300 is provided with an inlet 310 and an outlet 320, and at least part of the water pipe 300 is disposed within the receiving cavity 101 and exchanges heat with the heat-conducting medium 200. The refrigeration system 400 includes an evaporation pipe 410, which is disposed within the cooling box 100 and used to cool the heat-conducting medium 200. By integrating the cooling box 100, the heat-conducting medium 200, the water pipe 300, and the refrigeration system 400, a new type of cold water production method is achieved, transforming from a passive, slow, and easily contaminated existing technology to an active, efficient, and relatively isolated method. This not only greatly improves the speed and continuous supply capacity of cold water production, meeting users' demand for fast and sufficient cold water, but also significantly improves water quality through physical isolation and efficient heat exchange, avoiding odor and spoilage problems. It provides instant cooling, eliminates the need for waiting to drink cold water, and ensures that cold water is clean and hygienic, thus improving the overall quality and safety of drinking water.

[0073] Secondly, this application also provides a refrigerator, which includes the cold water production device as described in the above embodiments.

[0074] It is understood that since the cold water production equipment has the beneficial effects of the above embodiments, the refrigerator will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this embodiment will not repeat it.

[0075] In one alternative implementation, the refrigerator is provided with a compressor compartment and a refrigerator compartment, and the cold water production equipment is installed in the compressor compartment or the refrigerator compartment, which can be designed according to the overall structure and internal space layout of the refrigerator.

[0076] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application.
