[0013]During ice making, the reversing valve can be switched so that the valve inlet connects to the second outlet. This allows the refrigerant to circulate between the compressor, the refrigerator, the reversing valve, and the chilled water tank. After the water in the chilled water tank cools down due to the refrigerant's vaporization and heat absorption, the first water pump can be controlled to draw the chilled water from the tank into the refrigerator. The refrigerator then uses the refrigerant's vaporization and heat absorption to make ice from the chilled water. In this process, the refrigerant flows sequentially through the refrigerator and the chilled water tank; it is first used for ice making and then for chilling water. The refrigerant temperature for ice making is lower than that for chilled water, ensuring efficient refrigerant utilization. Furthermore, the chilled water tank serves as a storage tank, continuously supplying chilled water to the refrigerator. Combined with the refrigerator's use of a lower-temperature refrigerant for ice making, this helps shorten the ice-making time.

[0042] Reference Figures 1 to 3 As shown, this embodiment provides a cold water ice-making device, which includes a compressor 100, a refrigerator 200, a reversing valve 300, a cold water tank 400, and a first water pump 510. The refrigerant inlet of the refrigerator 200 is connected to the refrigerant outlet of the compressor 100; the valve inlet of the reversing valve 300 is connected to the refrigerant outlet of the refrigerator 200, and the first outlet of the reversing valve 300 is connected to the refrigerant inlet of the compressor 100; the refrigerant inlet of the cold water tank 400 is connected to the second outlet of the reversing valve 300, and the refrigerant outlet of the cold water tank 400 is connected to the refrigerant inlet of the compressor 100; the water inlet of the first water pump 510 is connected to the water outlet of the cold water tank 400, and the water outlet of the first water pump 510 is connected to the water inlet of the refrigerator 200.
[0043] During ice making, the reversing valve 300 can be switched so that the valve inlet and the second outlet are connected. This allows the refrigerant to circulate between the compressor 100, the refrigerator 200, the reversing valve 300, and the cold water tank 400. After the water in the cold water tank 400 cools down due to the refrigerant's vaporization and heat absorption, the first water pump 510 can be controlled to draw the cold water from the cold water tank 400 into the refrigerator 200. The refrigerator 200 then uses the refrigerant's vaporization and heat absorption to make ice from the cold water. The refrigerant flows sequentially through the refrigerator 200 and the cold water tank 400; it is first used for ice making and then for cooling water. The refrigerant temperature for ice making is lower than that for cooling water, ensuring efficient use of the refrigerant. Furthermore, the cold water tank 400 serves as a cold water reservoir, continuously supplying cold water to the refrigerator 200. Combined with the refrigerator 200's use of a lower-temperature refrigerant for ice making, this helps shorten the ice-making time.
[0044] Furthermore, during ice making, the reversing valve 300 can be switched so that the valve inlet connects to the first outlet, allowing the refrigerant to circulate between the compressor 100, the refrigerator 200, and the reversing valve 300. This maintains the cold water in the cold water tank 400 within a certain temperature range, helping to reduce the risk of ice formation in the cold water tank 400. Understandably, the switching of the reversing valve 300 can be based on parameters such as the time interval, the number of ice-making cycles, and the water temperature in the cold water tank 400.
[0045] In this embodiment, the cold water ice-making device also includes a thermostat (not shown), which is located inside the cold water tank 400 and electrically connected to the reversing valve 300. In this embodiment, the reversing valve 300 can control the switching of the reversing valve 300 based on the temperature information of the water in the cold water tank 400 detected by the thermostat, so as to maintain the cold water in the cold water tank 400 within a preset temperature range, which is stable and reliable, effectively preventing the cold water tank 400 from freezing, and providing a continuous supply of cold water to the ice-making refrigerator 200. The specific structure of the thermostat is prior art and is not the focus of this application, so it will not be described in detail in this embodiment.
[0046] In one feasible implementation, when the thermostat detects that the water temperature in the cold water tank 400 is less than T1℃, the reversing valve 300 switches to connect the valve inlet to the first outlet, so that the refrigerant circulates between the compressor 100, the refrigerator 200, and the reversing valve 300; when the thermostat detects that the water temperature in the cold water tank 400 is greater than T2℃, the reversing valve 300 switches to connect the valve inlet to the second outlet, so that the refrigerant circulates between the compressor 100, the refrigerator 200, the reversing valve 300, and the cold water tank 400; wherein, T1 < T2. It is understood that by setting the thermostat, the water temperature in the cold water tank 400 can be controlled between T1℃ and T2℃, which is convenient to implement, helps to reduce the switching frequency of the reversing valve 300, and extends the service life of the reversing valve 300.
[0047] For example, the value of T1 ranges from five to eight.
[0048] For example, the value of T2 ranges from eight to twelve.
[0049] For example, T1 is set to five and T2 is set to ten, which helps to maintain the water temperature in the cold water tank 400 and shorten the ice-making time.
[0050] In some embodiments, when the reversing valve 300 switches to connect the valve inlet and the first outlet, the compressor 100 can work intermittently to keep the refrigerator 200 at a temperature below freezing point, effectively preventing the ice inside the refrigerator 200 from melting.
[0051] In this embodiment, reference is made to Figure 2 and Figure 3 As shown, the refrigerator 200 includes a first cabinet 210 and a first refrigerant pipe 220 surrounding the first cabinet 210. The refrigerant inlet of the first refrigerant pipe 220 is connected to the refrigerant outlet of the compressor 100, and the refrigerant outlet of the first refrigerant pipe 220 is connected to the valve inlet of the reversing valve 300. The first cabinet 210 can store freshly made ice for immediate use. In this embodiment, the refrigerant absorbs heat from the first cabinet 210 through the first refrigerant pipe 220, raising the temperature inside the first cabinet 210 below the freezing point. This facilitates stable and reliable ice making and storage within the first cabinet 210, and helps reduce the waiting time for retrieving ice.
[0052] For example, the first refrigerant pipe 220 can be wound in the shape of a rectangular frame.
[0053] In one feasible implementation, the cold water ice-making device further includes an insulation sleeve 600, which is fitted over the refrigerator 200. It is understood that the insulation sleeve 600 wrapping around the first refrigerant pipe 220 helps reduce the amount of condensate produced by the first refrigerant pipe 220, and also helps to insulate the first housing 210, thus reducing energy consumption.
[0054] For example, the material of the insulation sleeve 600 can be insulation cotton.
[0055] In this embodiment, reference continues to be made to... Figure 2 and Figure 3 As shown, the cold water tank 400 includes a second housing 410 and a second refrigerant pipe 420 disposed within the second housing 410. The refrigerant inlet of the second refrigerant pipe 420 is located outside the second housing 410 and communicates with the second vent of the reversing valve 300. The refrigerant outlet of the second refrigerant pipe 420 is located outside the second housing 410 and communicates with the refrigerant inlet of the compressor 100. In this embodiment, the second refrigerant pipe 420 is in direct contact with the water in the cold water tank 400, which is beneficial for heat exchange between the refrigerant and the water, and helps to shorten the time for making ice from cold water.
[0056] For example, the second refrigerant pipe 420 may be spiral-shaped.
[0057] In this embodiment, the cold water ice-making device further includes a first water level sensor (not shown) disposed on the refrigerator 200. The first water level sensor is used to detect the water level inside the refrigerator 200. In this embodiment, the first water pump 510 is controlled to start and stop according to the water level information inside the refrigerator 200 detected by the first water level sensor, so as to ensure that there is enough cold water in the refrigerator 200 for ice making, and to effectively prevent the situation where too much water in the refrigerator 200 affects ice making.
[0058] It is understood that the cold water ice-making device also includes a controller (not shown), and the first water level sensor and the first water pump 510 are both electrically connected to the controller. The controller receives the water level information detected by the first water level sensor in the ice-making refrigerator 200 and controls the start and stop of the first water pump 510.
[0059] In this embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 As shown, the cold water ice-making device also includes a radiator 700, which is connected in series between the refrigerant outlet of the cold water tank 400 and the refrigerant inlet of the compressor 100. The radiator 700 is used to cool the refrigerant. It can be understood that the refrigerant cooled by the radiator 700 enters the compressor 100 for compression, so as to maintain a stable refrigeration temperature for the refrigerant, which is beneficial for ice making in the refrigerator 200 and for cooling water in the cold water tank 400.
[0060] In one feasible implementation, the radiator 700 includes a heat dissipation pipe 710, a heat dissipation assembly 720, and a cooling fan. The heat dissipation pipe 710 is connected in series between the refrigerant outlet of the cold water tank 400 and the refrigerant inlet of the compressor 100; in other words, the refrigerant inlet of the heat dissipation pipe 710 is connected to the refrigerant outlet of the cold water tank 400, and the refrigerant outlet of the heat dissipation pipe 710 is connected to the refrigerant inlet of the compressor 100. The heat dissipation assembly 720 includes multiple heat dissipation fins arranged side by side, and the heat dissipation pipe 710 passes through the heat dissipation fins. The cooling fan is located on one side of the heat dissipation assembly 720 and is used to blow air onto or draw air away from the heat dissipation assembly 720 to keep the heat dissipation fins at a lower temperature. This facilitates the heat exchange between the heat dissipation fins and the refrigerant through the heat dissipation pipe 710, thereby reducing the temperature of the refrigerant and ensuring stability and reliability.
[0061] For example, the heat dissipation pipe 710 includes a plurality of parallel pipe sections arranged in parallel, and at least some of the parallel pipe sections pass through all the heat dissipation fins, which is beneficial for cooling the refrigerant.
[0062] For example, the cooling fan includes a first fan 731 and a second fan 732, and the heat dissipation assembly 720 is located between the first fan 731 and the second fan 732. The first fan 731 blows air onto the heat dissipation assembly 720, and the second fan 732 draws air away from the heat dissipation assembly 720, which is beneficial to the cooling of the refrigerant.
[0063] In this embodiment, reference is made to Figure 1 and Figure 4 As shown, the cold water ice-making device also includes a housing 800, and a compressor 100, a refrigerator 200, a reversing valve 300, a cold water tank 400, and a radiator 700 are all housed within the housing 800. The refrigerator 200 and the cold water tank 400 can be located on the front side of the housing 800, while the compressor 100 and the radiator 700 are located on the rear side of the housing 800.
[0064] For example, the first fan 731 can blow air outside the housing 800 to the heat dissipation assembly 720.
[0065] For example, the cold water ice-making device also includes an exhaust pipe 740, a first end of which extends to a second fan 732, and a second end of which communicates with an exhaust port on the housing 800. Air drawn from the heat dissipation assembly 720 by the second fan 732 can be exhausted to the outside of the housing 800 through the exhaust pipe 740.
[0066] In this embodiment, reference is made to Figure 1 As shown, the cold water ice-making device also includes a water purifier 900, the outlet of which is connected to the inlet of the cold water tank 400. In this embodiment, the water purifier 900 can directly supply water to the cold water tank 400, which is convenient, reliable, and ensures good water quality.
[0067] For example, the water purifier 900 is disposed within the housing 800.
[0068] In one feasible implementation, the cold water ice-making device further includes a second water level sensor (not shown) disposed on the cold water tank 400, which is used to detect the water level in the cold water tank 400. In this embodiment, the water purifier 900 controls the start and stop of water supply to the cold water tank 400 based on the water level information detected by the second water level sensor, so as to maintain a stable water level in the cold water tank 400.
[0069] Understandably, both the second water level sensor and the water purifier 900 are electrically connected to the controller. The controller receives the water level information detected by the second water level sensor in the cold water tank 400 and controls the water purifier 900 to supply water to the cold water tank 400.
[0070] In this embodiment, reference continues to be made to... Figure 1As shown, the cold water ice-making device also includes a second water pump 520 and a water outlet (not shown). The inlet of the second water pump 520 is connected to the outlet of the cold water tank 400, and the outlet of the second water pump 520 is connected to the water outlet. In this embodiment, cold water in the cold water tank 400 can be drawn by the second water pump 520 to the water outlet for drinking by the user, improving the applicability of the cold water ice-making device.
[0071] For example, the working process of a cold water ice-making device is as follows:
[0072] First, the water purifier 900 adds water to the cold water tank 400. When the second water level sensor detects that the cold water tank 400 is full, the first water pump 510 is started to pump the water in the cold water tank 400 into the refrigerator 200. The first water pump 510 is stopped when the first water level sensor detects that the water level in the refrigerator 200 has reached the ice-making requirement.
[0073] Then, switch the reversing valve 300 to connect the valve inlet and the second outlet and start the compressor 100. The refrigerant circulates between the compressor 100, the refrigerator 200, the reversing valve 300 and the cold water tank 400 to achieve ice making and cooling water.
[0074] Understandably, during the operation of the cold water ice-making device, when the second water level sensor detects that the cold water tank 400 is short of water, the water purifier 900 can be controlled to refill the cold water tank 400.
[0075] Understandably, during the operation of the cold water ice-making device, the need to make 200 ice cubes in a refrigerator can be met by repeatedly starting and stopping the first water pump 510.
[0076] Understandably, during the operation of the cold water ice-making device, when the thermostat detects that the water temperature in the cold water tank 400 is less than T1℃, the reversing valve 300 switches to connect the valve inlet to the first outlet, and the compressor 100 can operate intermittently. When the thermostat detects that the water temperature in the cold water tank 400 is greater than T2℃, the reversing valve 300 switches to connect the valve inlet to the second outlet.
[0077] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0078] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
