Description

[0002] A water purifier is an appliance that first heats water to boiling, then rapidly cools it to a desired temperature using a built-in cooling device. Most water purifiers on the market use a mixture of hot and cold water to cool boiling water; the water obtained through this cooling method is called "yin-yang water" (or "mixed-hot water").

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0061] To make the objectives, technical solutions, and advantages disclosed in the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this application and are not intended to limit the embodiments of this application.

[0062] This application provides a water cooling system. Figure 1 This is a schematic diagram of a water cooling system provided in an embodiment of this application. Figure 1 ,like Figure 1 As shown, the water cooling system includes a first cooling unit, a second cooling unit, and a control unit. The first cooling unit includes a cooling channel 1 and a first cooling chamber 2. The cooling channel 1 holds the cooling solution, and the first cooling chamber 2 includes a first inlet 21 and a first outlet 22. The cooling channel 1 surrounds the first cooling chamber 2. The second cooling unit includes a refrigeration device 3 and a second cooling chamber 4. The refrigeration device 3 includes a refrigeration material, and the second cooling chamber 4 includes a second inlet 41 and a second outlet 42. The refrigeration device 3 is located on the outer surface of the second cooling chamber 4. The first outlet 22 communicates with the second inlet 41. The cooling channel 1, the first cooling chamber 2, the refrigeration device 3, and the second cooling chamber 4 are all electrically connected to the control unit.

[0063] In this embodiment, boiling water in the first cooling box 2 is cooled by cooling channel 1 to obtain room temperature water, and room temperature water in the second cooling box 4 is cooled by refrigeration device 3 to obtain low temperature water, thereby providing boiled water at different temperatures to meet the water needs of different users.

[0064] In this embodiment, the first cooling unit utilizes the heat exchange between the cooling channel 1 and the first cooling chamber 2 to cool the boiling water in the first cooling chamber 2 to room temperature. The cooling channel 1 surrounds the first cooling chamber 2, and the two are connected by the top of the cooling channel 1 and the top of the first cooling chamber 2. After the control unit injects a cooling solution with an initial temperature lower than the boiling water temperature into the cooling channel 1, the cooling solution in the cooling channel 1 will exchange heat with the boiling water in the first cooling chamber 2. Through heat exchange, the temperature of the cooling solution increases, and the temperature of the boiling water decreases.

[0065] Optionally, the cooling solution can be tap water.

[0066] In this embodiment, the second cooling unit utilizes the cooling effect of the refrigeration device 3 to cool the room temperature water in the second cooling box 4 to a low temperature. The refrigeration device 3 is located on the outer surface of the second cooling box 4 and is electrically connected to the control unit. When the control unit activates the refrigeration device 3, the refrigeration material in the refrigeration device 3, after being energized, will cause a low-temperature portion to appear in the refrigeration device 3, and this low-temperature portion will contact the second cooling box 4. The low-temperature portion in the refrigeration device 3 will produce a cooling effect on the second cooling box 4, lowering the temperature of the room temperature water in the second cooling box 4.

[0067] In some possible embodiments, the cooling principle of the cooling device 3 is based on the Peltier effect. The cooling device 3 contains multiple pairs of thermocouples composed of P-type and N-type semiconductor elements connected together. When a direct current is applied to the circuit containing the thermocouples, one end of the thermocouple releases heat, and the other end absorbs heat. When the heat-absorbing end of the thermocouple is brought into contact with the second cooling chamber 4, the water temperature in the second cooling chamber 4 will decrease. The intensity of heat absorption is directly proportional to the current intensity, and the intensity of heat absorption is related to the types of P-type and N-type semiconductors.

[0068] Optionally, the cooling material can be a semiconductor material. Semiconductor materials include bismuth telluride (Bi₂Te₃) and its alloys, as well as lead selenide (PbSe). These materials possess excellent thermoelectric properties, which are key to achieving semiconductor cooling.

[0069] Figure 2 This is a schematic diagram of a water cooling system provided in an embodiment of this application. Figure 2 ,like Figure 2 As shown, the cooling channel 1 includes a third water inlet 11 and a third water outlet 1212. The third water inlet 11 is connected to the third water inlet pipe 13, and a fifth water valve 131 is installed on the third water inlet pipe 13. The third water outlet 12 is connected to the fourth water outlet pipe 14.

[0070] In one optional embodiment, when cooling channel 1 needs to cool the first cooling box 2, the fifth water valve 131 is opened, and tap water (i.e., the cooling solution) enters cooling channel 1 through the third inlet 11 via the third inlet pipe 13. Once cooling channel 1 is full of tap water, the fifth water valve 131 is closed, stopping the injection of tap water into cooling channel 1. After the temperature of the tap water in cooling channel 1 rises due to heat exchange with the boiling water in the first cooling box 2, the fifth water valve 131 is reopened for a period of time to continue injecting tap water into cooling channel 1. The original tap water in cooling channel 1 is squeezed out and discharged through the third outlet 12 and the fourth outlet pipe 14. This operation is repeated, replacing the tap water in cooling channel 1 multiple times, until the boiling water in the first cooling box 2 cools to room temperature. This method of repeatedly replacing tap water for heat exchange not only cools the boiling water in the first cooling box 2 but also saves water and electricity.

[0071] Optionally, the opening time of the fifth water valve 131 can be based on the time when the cooling channel 1 is filled with tap water each time the tap water is replaced.

[0072] In another alternative embodiment, while cooling the first cooling chamber 2 through the cooling channel 1, the fifth water valve 131 can be kept open until the boiling water in the first cooling chamber 2 cools down to room temperature, at which point the fifth water valve 131 is closed. When the fifth water valve 131 remains open, the cooled tap water, which has been heated through heat exchange, is quickly replaced by fresh tap water, resulting in a better cooling effect of the cooling channel 1 and faster cooling of the boiling water in the first cooling chamber 2 to room temperature.

[0073] Figure 3 This is a schematic diagram of a water cooling system provided in an embodiment of this application. Figure 3 ,like Figure 3 As shown, in the first cooling tank 2, the first inlet 21 is connected to the first inlet pipe 23, and the first inlet pipe 23 is equipped with a first water valve 231. The first outlet 22 is connected to the first outlet pipe 24. Boiling water that needs to be cooled is injected into the first cooling tank 2 through the first inlet pipe 23 and the first inlet 21. After the boiling water and the tap water in the cooling channel 1 are cooled to room temperature through heat exchange, the room temperature water can be discharged from the first outlet 22 through the first outlet pipe 24. Users can discharge the room temperature water into the second cooling tank 4 for further cooling as needed, or directly take the room temperature water for drinking.

[0074] In some possible embodiments, such as Figure 3As shown, the first inlet 21 is located on the top surface of the first cooling chamber 2, and the first outlet 22 is located on the bottom surface of the first cooling chamber 2. The position of the first inlet 21 on the top surface of the first cooling chamber 2 is further away from the position of the first outlet 22 on the bottom surface of the first cooling chamber 2. Placing the first inlet 21 and the first outlet 22 diagonally opposite each other ensures that the first outlet 22 is as far away from the first inlet 21 as possible, thereby guaranteeing the cooling effect of the water.

[0075] In some possible embodiments, to enhance the heat exchange between the cooling channel 1 and the first cooling chamber 2, the side of the first cooling chamber 2 that contacts the cooling solution is made of a material with good thermal conductivity, such as stainless steel. Stainless steel can enhance thermal conductivity, allowing the cooling solution in the cooling channel 1 and the boiling water in the first cooling chamber 2 to quickly complete the temperature exchange process.

[0076] Figure 4 This is a schematic diagram of a water cooling system provided in an embodiment of this application. Figure 4 ,like Figure 4 As shown, the first cooling box 2 includes a baffle plate 25. The baffle plate 25 is located on the bottom surface of the first cooling box 2, and the position of the baffle plate 25 on the bottom surface of the first cooling box 2 is close to the position of the first water inlet 21 on the top surface of the first cooling box 2.

[0077] In this embodiment, after the boiling water in the first cooling tank 2 has been cooled and partially used, it is necessary to replenish the first cooling tank 2 with boiling water in order not to affect subsequent use. The baffle 25 installed inside the first cooling tank 2 can act as a buffer when replenishing boiling water, preventing the temperature of the room temperature water near the first outlet 22 in the first cooling tank 2 from rising rapidly due to the newly injected boiling water. This reduces the impact of the newly added boiling water on the outlet water temperature during the replenishment process of the first cooling tank 2.

[0078] In some possible embodiments, in order to fully utilize the buffering effect of the baffle plate 25, the first water inlet pipe 23 extends into the interior of the first cooling box 2, and the outlet of the first water inlet pipe 23 is lower than the top of the baffle plate 25.

[0079] Figure 5 This is a schematic diagram of a water cooling system provided in an embodiment of this application. Figure 5 ,like Figure 5 As shown, the first cooling chamber 2 includes a water level probe module 26. The water level probe module 26 is located inside the first cooling chamber 2. The water level probe module 26 is used to indicate the water level height.

[0080] In this embodiment, the water level probe module 26 is electrically connected to the control unit. The control unit can control the opening and closing of the first water valve 231 based on the water level indicated by the water level probe module 26. When the water level probe module 26 indicates a water level lower than a first preset height, the control unit will control the opening of the first water valve 231 to replenish boiling water into the first cooling tank 2. When the water level probe module 26 indicates a water level reaching a second preset height, the control unit will control the closing of the first water valve 231 to stop replenishing boiling water into the first cooling tank 2. By setting the water level probe module 26, the water in the first cooling tank 2 can be kept at or above the first preset height, thereby ensuring the appropriate water output.

[0081] Optionally, users can set and adjust the size of the first preset height and the second preset height according to their needs.

[0082] In some possible embodiments, the water level probe module 26 includes a high water level probe 261 and a medium water level probe 262. The water level indicated by the medium water level probe 262 is a first preset height, and the water level indicated by the high water level probe 261 is a second preset height. Water replenishment stops when the water level in the first cooling tank 2 exceeds the high water level probe 261, and water replenishment starts when the water level is below the medium water level probe 262.

[0083] Figure 6 This is a schematic diagram of a water cooling system provided in an embodiment of this application. Figure 6 ,like Figure 6 As shown, the second water inlet 41 is connected to the second water inlet pipe 43, and the second water inlet pipe 43 is equipped with a second water valve 431. When the second water valve 431 is opened, the room temperature water in the first cooling box 2, which has been cooled from boiling water, will enter the second cooling box 4 in sequence through the first water outlet 22, the first water outlet pipe 24, the second water inlet 41, and the second water inlet pipe 43.

[0084] In the embodiments of this application, such as Figure 6 As shown, the first water outlet pipe 24 and the second water inlet pipe 43 are connected to the second water outlet pipe 44 via a T-joint. A third water valve 441 is installed on the second water outlet pipe 44. Users can obtain room temperature water for drinking by opening the third water valve 441.

[0085] In the embodiments of this application, such as Figure 6 As shown, the second water outlet 42 is connected to the third water outlet pipe 45. Users can obtain low-temperature water through the third water outlet pipe 45.

[0086] In one optional embodiment, a fourth water valve is provided on the third water outlet pipe 45. The second cooling tank 4 can continuously store low-temperature water, so that the user can directly open the fourth water valve to obtain low-temperature water when needed. Furthermore, if the second cooling tank 4 is equipped with a temperature measuring device, the user can also obtain low-temperature water only when the water temperature reaches the desired level. Because the third water outlet pipe 45 is equipped with a water valve, the third water outlet pipe 45 can be located at any position in the second cooling tank 4, such as the top, bottom, or side of the second cooling tank 4. The third water outlet pipe 45 is preferably located on the bottom of the second cooling tank 4 so that low-temperature water can be obtained even when the water volume in the second cooling tank 4 is low.

[0087] In another optional embodiment, the third water outlet pipe 45 is located on the top or side of the second cooling box 4, and no water valve is installed on the third water outlet pipe 45. When the user needs to obtain low-temperature water, the second water valve 431 is opened, and the control unit will start the refrigeration device 3. The room-temperature water in the first cooling box 2, which has been cooled from boiling water, will be injected into the second cooling box 4, and will flow out from the third water outlet pipe 45 when the water level reaches the height of the second water outlet 42. This method of obtaining low-temperature water by cooling it only when needed saves more energy because it does not require the refrigeration device 3 to be started for a long time. However, since the room-temperature water has a limited residence time in the second cooling box 4, it may not be able to be cooled to the required temperature.

[0088] Figure 7 This is a schematic diagram of a water cooling system provided in an embodiment of this application. Figure 7 ,like Figure 7 As shown, the water cooling system includes a temperature measuring unit. The temperature measuring unit includes a first temperature sensor 5, a second temperature sensor 6, and a third temperature sensor 7. The first temperature sensor 5, the second temperature sensor 6, and the third temperature sensor 7 are electrically connected to the control unit. The first temperature sensor 5 is located inside the cooling channel 1, the second temperature sensor 6 is located inside the first cooling chamber 2, and the third temperature sensor 7 is located inside the second cooling chamber 4. By setting up the temperature measuring unit, ambient temperature water and low-temperature water at the desired temperature can be obtained, fully meeting the user's water usage needs.

[0089] In some possible implementations, the default temperature for room temperature water is 40 degrees Celsius, and the default temperature for cold water is 10 degrees Celsius. Users can set the temperatures of room temperature water and cold water according to their own needs.

[0090] In this embodiment, the first temperature sensor 5 is located near the third water outlet 12 within the cooling channel 1. The function of the first temperature sensor 5 is to measure the temperature of the tap water in the cooling channel 1.

[0091] In some possible embodiments, the control unit is used to control the water cooling system to inject cooling solution into the cooling channel 1 when the value measured by the first temperature sensor 5 is higher than a first preset temperature. When the temperature measured by the first temperature sensor 5 exceeds the first preset temperature, the control unit controls the fifth water valve 131 in the water cooling system to open. By injecting new tap water to replace the original tap water, water conservation can be achieved, and the cooling of the high-temperature water in the first cooling tank 2 can be accelerated.

[0092] In this embodiment, the second temperature sensor 6 is located inside the first cooling tank 2 near the first water outlet 22. The function of the second temperature sensor 6 is to measure the water temperature exiting the first cooling tank 2 so that the user can obtain room temperature water that meets the expected temperature.

[0093] In some possible embodiments, the control unit is used to control the water cooling system to inject cooling solution into the cooling channel 1 when the numerical difference between the first temperature sensor 5 and the second temperature sensor 6 is lower than a second preset temperature. When the numerical difference between the first temperature sensor 5 and the second temperature sensor 6 is lower than the second preset temperature, it indicates that the cooling effect of the tap water in the cooling channel 1 is very weak. At this time, the control unit will control the fifth water valve 131 in the water cooling system to open. By injecting new tap water to replace the original tap water, the cooling effect of the cooling channel 1 can be guaranteed.

[0094] In this embodiment, the third temperature sensor 7 is located inside the first cooling box 2. The function of the third temperature sensor 7 is to measure the outlet water temperature of the second cooling box 4.

[0095] In some possible embodiments, the control unit is also configured to control the refrigeration device 3 to start and cool the second cooling box 4 when the value measured by the third temperature sensor 7 is higher than the third preset temperature. When the temperature measured by the third temperature sensor 7 exceeds the user-set low-temperature water temperature, the control unit controls the refrigeration device 3 to start. When the temperature measured by the first temperature sensor 5 reaches the user-set low-temperature water temperature, the control unit controls the refrigeration device 3 to shut down, so that the user can obtain low-temperature water at the expected temperature, and also saves energy and electricity.

[0096] In this embodiment, boiling water in the first cooling chamber 2 is cooled to room temperature through cooling channel 1, and room temperature water in the second cooling chamber 4 is cooled to low temperature through refrigeration device 3, thereby providing boiled water at different temperatures to meet the water needs of different users. Moreover, by setting a temperature measuring unit, users can specifically set the temperature of room temperature water and the temperature of low temperature water according to their own needs.

[0097] This application also provides a water cooling method applied to the above-mentioned water cooling system. Figure 8 This is a schematic flowchart of a water cooling method provided in an embodiment of this application, as shown below. Figure 8 As shown, the method includes:

[0098] S801 injects the first solution into the first cooling tank through the water cooling system;

[0099] S802 injects cooling solution into the cooling channel through a water cooling system;

[0100] S803 injects the second solution from the first cooling tank into the second cooling tank via a water cooling system; the second solution is the solution after the first solution has been cooled.

[0101] S804 uses a refrigeration device to cool the second solution in the second cooling chamber to obtain a third solution; the third solution is the solution obtained after cooling the second solution.

[0102] In this embodiment, the first water valve 231 of the water cooling system is opened to inject a first solution into the first cooling tank 2. The fifth water valve 131 of the water cooling system is opened to inject a cooling solution into the cooling channel 1. Due to the heat exchange between the first cooling tank 2 and the cooling channel 1, the first solution in the first cooling tank 2 will cool down and become a second solution. The user can directly use the second solution or continue to cool it.

[0103] In this embodiment, when cooling the second solution, the second water valve 431 in the water cooling system is opened, and the second solution in the first cooling tank 2 is injected into the second cooling tank 4. The second solution in the second cooling tank 4 is cooled by the refrigeration device 3, and the second solution will cool down and become the third solution.

[0104] In this embodiment, the cooling solution is tap water, the first solution is boiling water, the second solution is room temperature water, and the third solution is low temperature water. Through this water cooling system, boiling water can be cooled to room temperature and low temperature, thereby meeting the water needs of different users.

[0105] This application also provides a cooling method for a first cooling unit, which can make the operation of the water cooling system more intelligent. The method is as follows:

[0106] S1. Open the first water valve 231 to inject boiling water into the first cooling tank 2. After the boiling water in the first cooling tank 2 reaches a certain water level, close the first water valve 231.

[0107] S2. Open the fifth water valve 131 to inject tap water into the cooling channel 1. After the cooling channel 1 is full of tap water, close the fifth water valve 131. The opening time of the fifth water valve 131 can be 30 seconds or other times, depending on whether the cooling channel 1 is full of tap water. This step can be performed after step S1 or simultaneously with step S1.

[0108] S3. When the value of the first temperature sensor 5 is higher than the first preset temperature or the difference between the values ​​of the first temperature sensor 5 and the second temperature sensor 6 is lower than the second preset temperature, the fifth water valve 131 is opened again; after a period of time, the fifth water valve 131 is closed. The opening time of the fifth water valve 131 is consistent with the opening time of the fifth water valve 131 in step S2.

[0109] S4. The temperature inside the first cooling chamber 2 is measured in real time by the second temperature sensor 6. If the temperature inside the first cooling chamber 2 reaches the preset temperature, the cooling process from boiling water to room temperature water is completed; if the temperature inside the first cooling chamber 2 is higher than the preset temperature, the cooling process in steps S3 and S4 needs to be repeated.

[0110] In this embodiment, tap water is used to cool boiling water, and the opening and closing of the tap water inlet valve is controlled by the temperature values ​​and temperature difference values ​​of two temperature sensors, thus achieving automated control of cooling boiling water to room temperature. Moreover, the method of quantitatively injecting tap water can maximize the use of the cooling effect of tap water, thereby achieving the cooling effect and minimizing water waste.

[0111] This application embodiment also provides a method for replenishing water in the first cooling tank, which is for scenarios where some water has been discharged from the first cooling tank 2. The method is as follows:

[0112] S1. If the water level in the first cooling tank 2 is lower than the first preset height indicated by the water level probe 262, open the first water valve 231 to replenish boiling water into the first cooling tank 2.

[0113] S2. If the water level in the first cooling tank 2 reaches the second preset height indicated by the high water level probe 261, close the first water valve 231 and stop adding boiling water to the first cooling tank 2.

[0114] This application also provides a cooling method for a second cooling unit, which can make the operation of the water cooling system more intelligent. The method is as follows:

[0115] S1. Start the refrigeration unit 3;

[0116] S2. The temperature inside the second cooling chamber 4 is measured in real time by the third temperature sensor 7. If the temperature inside the second cooling chamber 4 reaches the preset temperature, the refrigeration device 3 is turned off, completing the cooling process from room temperature water to low temperature water.

[0117] This application also provides a hot water dispenser, including the aforementioned water cooling system. This hot water dispenser can provide both room temperature and cold water, and the water temperature can be set by the user, greatly satisfying user needs.
