The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order; the cold water mentioned in the specification and claims of this invention includes room temperature water.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] Reference Figure 1-2The first embodiment of this application proposes a water purifier, which includes: a water tank 100, a cold storage chamber 200, a refrigeration component 300, and a first water outlet 400; the cold storage chamber 200 is provided with a cold storage cavity and a heat exchange tube 220; the heat exchange tube 220 is disposed in the cold storage cavity; the water inlet end of the heat exchange tube 220 is connected to the water tank 100, and its water outlet end is connected to the first water outlet 400; the cold storage cavity is filled with a phase change cold storage material 210, the phase change cold storage material 210 wraps the outer wall of the heat exchange tube 220, the refrigeration end of the refrigeration component 300 extends into the cold storage cavity and exchanges heat with the phase change cold storage material 210 and is inserted into the phase change cold storage material 210; the first water outlet 400 is used to provide users with ice water.

[0027] Specifically, the cooling end of the refrigeration component 300 is inserted into the phase change cold storage 210 to exchange heat with the phase change cold storage 210.

[0028] In this embodiment, the refrigeration component 300 is activated, and the phase change cold storage material 210 in the cold storage chamber is continuously cooled by the refrigeration end of the refrigeration component 300. At the same time, the phase change cold storage material 210 changes from a liquid state to a solid state. Since the phase change cold storage material 210 wraps the outer wall of the heat exchange tube 220, room temperature water is introduced from the water tank 100 at the water inlet end of the heat exchange tube 220. When the room temperature water passes through the heat exchange tube 220, the phase change cold storage material 210 in the cold storage chamber is continuously cooled by the refrigeration end of the refrigeration component 300, which in turn causes the room temperature water in the heat exchange tube 220 to also be continuously cooled, so that the room temperature water is converted into ice water and then output to the first water outlet 400. The user can then freely obtain ice water through the first water outlet 400. If ice water is not needed, the refrigeration component 300 is in the off state, and the room temperature water in the water tank 100 is directly output to the first water outlet 400 after passing through the heat exchange tube 220, thereby completing the production of room temperature water. This allows the water purifier to produce not only room temperature water but also ice water, improving user satisfaction.

[0029] Specifically, the phase change cold storage 210 is composed of a cold storage solution and a phase change cold storage material mixed together. When the refrigeration component 300 is activated, the cold storage solution in the cold storage chamber is continuously cooled through the cooling end of the refrigeration component 300. At the same time, the phase change cold storage material changes from a liquid state to a solid state. The continuously cooled cold storage solution can absorb heat from the room temperature water in the heat exchange tube 220, causing the room temperature water in the heat exchange tube 220 to turn into ice water. Furthermore, because the phase change cold storage material changes from a liquid state to a solid state, it has highly efficient energy storage characteristics. It can absorb and store a large amount of cold energy when the refrigeration component 300 is working, and then slowly release it when needed. This allows the water purifier to continuously output ice water to the first water outlet 400 for a period of time even when the refrigeration component 300 is not working.

[0030] Reference Figure 1 The heat exchange tube 220 is a multi-bend tube.

[0031] In this embodiment, the cold storage chamber 200 is provided with an inlet and an outlet pipe. The heat exchange tube 220 is coiled and placed inside the cold storage chamber, and then the phase change cold storage material 210 is filled into the cold storage chamber. This increases the length of the heat exchange tube 220 stored in the cold storage chamber, thereby increasing the contact area between the heat exchange tube 220 and the phase change cold storage material 210 and extending their contact time. This improves the heat exchange efficiency, allowing the room temperature water output from the water tank 100 to be cooled to the required temperature more quickly.

[0032] Reference Figure 1-2 The water purifier also includes a UV lamp assembly 110, the light-emitting end of which is located inside the water tank 100.

[0033] In this embodiment, the UV lamp assembly 110 is used to sterilize the water in the water tank 100.

[0034] Reference Figure 1 The refrigeration assembly 300 includes a refrigeration drive 310, a refrigerant pipeline 320, and an evaporator 330; the two ends of the refrigerant pipeline 320 are respectively connected to the refrigeration drive 310 and the evaporator 330; the evaporator 330 is located in the phase change cold storage 210.

[0035] In this embodiment, the refrigeration drive unit 310 starts working and delivers refrigerant to the evaporator 330 through the refrigerant pipeline 320. Since the evaporator 330 is inserted into the phase change cold storage 210, the refrigerant in the evaporator 330 exchanges heat with the phase change cold storage 210. The refrigerant evaporates and absorbs the heat of the phase change cold storage 210, while the phase change cold storage 210 is cooled. The evaporated refrigerant returns to the refrigeration drive unit 310 through the refrigerant pipeline 320 to complete one refrigeration cycle.

[0036] Reference Figure 1 The water purifier also includes a first water pump 500, the inlet of which is connected to the water tank 100 and the outlet of which is connected to the inlet of the heat exchange tube 220.

[0037] In this embodiment, the first water pump 500 improves the water supply efficiency from the water tank 100 to the heat exchange tube 220, enabling the water purifier to produce ice water more quickly. Simultaneously, the pressurization effect of the first water pump 500 also helps to increase the water flow rate within the heat exchange tube 220, further improving heat exchange efficiency. Utilizing the energy storage function of the phase change cryogenic storage device 210, combined with the continuous operation of the first water pump 500, ensures a continuous supply of ice water for a period of time and increases the amount of ice water output during this period.

[0038] In summary, the first water pump 500 further improves the water supply efficiency and heat exchange efficiency of the water purifier.

[0039] Furthermore, a first extension water pipe 1300 connects the inlet of the first water pump 500 to the outlet of the water tank 100, and also connects the outlet of the first water pump 500 to the inlet of the heat exchange tube 220, and the outlet of the heat exchange tube 220 to the inlet of the first water outlet 400. The first extension water pipe 1300 allows for flexible installation of the water tank 100, the first water pump 500, the cold storage chamber 200, and the first water outlet 400.

[0040] Reference Figure 1 The water purifier also includes a raw water tank 600 and a membrane filter element 700; the water inlet of the membrane filter element 700 is connected to the raw water tank 600, and the pure water end of the membrane filter element 700 is connected to the drinking water tank 100.

[0041] In this embodiment, the raw water tank 600 is used to store untreated tap water or other water sources, and the membrane filter 700 is used to filter the water output from the raw water tank 600. The water after being filtered by the membrane filter 700 enters the drinking water tank 100 to remove impurities, odors, residual chlorine and other harmful substances from the water, thereby improving the quality and taste of the water.

[0042] In summary, by adding a raw water tank 600 and a membrane filter 700, the water quality and taste of the water produced by the water purifier are improved, while maintaining the advantages of efficient and continuous water supply.

[0043] Specifically, the outlet of the raw water tank 600 is connected to the inlet of the membrane filter element 700, and the inlet of the raw water tank 600 is connected to the water supply outlet such as the faucet.

[0044] Furthermore, the water tank 100 is also equipped with a stirring component. The stirring end of the stirring component is inserted into the water in the water tank 100. The stirring component keeps the water in the water tank 100 in a constant state of flow, thereby slowing down the rate of microbial growth in the water in the water tank 100.

[0045] Furthermore, the membrane filter element 700 is equipped with a reverse osmosis membrane or nanofiltration membrane to remove ions, microorganisms, etc. from the water.

[0046] Reference Figure 1 The water purifier also includes a wastewater valve 800, the inlet of which is connected to the wastewater end of the membrane filter 700, and the outlet of which is connected to the raw water tank 600.

[0047] In this embodiment, the wastewater valve 800 is used for pressure limiting and flow restriction to ensure that the working water pressure is maintained inside the membrane filter element 700. The wastewater valve 800 is opened or closed according to a preset control strategy, such as timed discharge or water level control. When the wastewater valve 800 is open, the wastewater inside the membrane filter element 700 is sent back to the raw water tank 600 for secondary use.

[0048] In other embodiments, the outlet of the wastewater valve 800 is connected to an external accessory to directly discharge the wastewater discharged from the membrane filter element 700 into the external accessory, thereby avoiding an increase in impurities in the raw water tank 600.

[0049] Reference Figure 1 The water purifier also includes a pressurizing component 900, the inlet of which is connected to the raw water tank 600, and the outlet of which is connected to the inlet of the membrane filter element 700.

[0050] In this embodiment, the pressurization component 900 is used to increase the inlet water pressure of the membrane filter element 700, ensuring that the membrane filter element 700 can stop water flow normally. Specifically, the pressurization component 900 is used to increase the pressure of the water transmitted from the raw water tank 600 to the membrane filter element 700, ensuring that the water in the raw water tank 600 can flow smoothly into the membrane filter element 700 and overcome the resistance that may be generated during the filtration process.

[0051] Specifically, the booster assembly 900 includes a booster pump, a pressure sensor, and a control unit. The inlet of the booster pump is connected to the raw water tank 600, and the outlet of the booster pump is connected to the membrane filter element 700. The pressure sensor is located inside the booster pump and is connected to the control unit. The control unit controls the booster pump to achieve precise water pressure regulation and detection.

[0052] Furthermore, a third extension water pipe 1500 is connected between the outlet of the raw water tank 600 and the inlet of the booster assembly 900. A third extension water pipe 1500 is also connected between the outlet of the booster assembly 900 and the inlet of the membrane filter element 700. A third extension water pipe 1500 is also connected between the first outlet of the membrane filter element 700 and the inlet of the drinking water tank 100. A third extension water pipe 1500 is also connected between the second outlet of the membrane filter element 700 and the inlet of the wastewater valve 800. The outlet of the wastewater valve 800 is connected to the return port of the raw water tank 600.

[0053] Reference Figure 2 The water purifier also includes an instant water heater 1000 and a second water outlet 1100. The water inlet of the instant water heater 1000 is connected to the water tank 100, and the water outlet of the instant water heater 1000 is connected to the second water outlet 1100. The second water outlet 1100 is used to provide hot water to the user.

[0054] In this embodiment, the instant water heater 1000 heats the water output from the water tank 100, that is, it heats the room temperature water output from the water tank 100 into hot water, and then the instant water heater 1000 outputs the hot water into the second water outlet 1100, through which the user can freely obtain hot water according to whether or not they need it.

[0055] Reference Figure 2 The water purifier also includes a second water pump 1200, the inlet of which is connected to the water tank 100, and the outlet of which is connected to the inlet of the instant water heater 1000.

[0056] Specifically, a second extension water pipe 1400 connects the inlet of the second water pump 1200 to the outlet of the water tank 100, a second extension water pipe 1400 also connects the outlet of the second water pump 1200 to the inlet of the instant heater 1000, and a second extension water pipe 1400 also connects the outlet of the instant heater 1000 to the inlet of the second water outlet 1100. The second extension water pipe 1400 allows for flexible installation of the second water pump 1200, the instant heater 1000, and the second water outlet 1100.

[0057] In this embodiment, the second water pump 1200 provides the flow power for the water in the instant water heater 1000, ensuring that hot water can be smoothly drawn from the water tank 100 and delivered to the user's desired location. Simultaneously, the pressurizing effect of the second water pump 1200 helps to increase the water flow rate in the instant water heater 1000, further improving heat exchange efficiency.

[0058] In some embodiments, the water purifier is further provided with a central processing unit, and an NTC sensor is provided in the cold storage chamber. The NTC sensor is communicatively connected to the central processing unit, and the central processing unit is controllably connected to the refrigeration assembly 300.

[0059] In this embodiment, the NTC sensor monitors the temperature of the phase change cryogenic material 210 in the cold storage chamber in real time and sends the temperature information to the central processing unit (CPU). The CPU compares the received temperature information with a preset temperature range for producing ice water. If the temperature of the phase change cryogenic material 210 in the cold storage chamber is higher than the preset range, the CPU sends a command to the refrigeration assembly 300 to activate the refrigeration assembly 300 to lower the temperature of the phase change cryogenic material 210 in the cold storage chamber. If the temperature of the phase change cryogenic material 210 in the cold storage chamber is lower than the preset range, the CPU and the refrigeration assembly 300 remain in a dormant state.

[0060] The water purifier has a cold storage chamber 200 with cold storage function, and functions for producing drinking water, ice water, room temperature water and hot water.

[0061] Cold storage chamber 200 cold storage function: The refrigeration component 300 is activated, which continuously cools the cold storage solution in the cold storage chamber, and at the same time changes the phase change cold storage material in the cold storage chamber from a liquid state to a solid state.

[0062] Drinking water production function: When the pressurization component 900 is activated, the raw water in the raw water tank 600 is pressurized by the pressurization component 900 and output to the membrane filter 700 to prepare drinking water. The drinking water after being filtered by the membrane filter 700 is input into the drinking water tank 100 for storage. The wastewater flows back to the raw water tank 600 after passing through the wastewater valve 800.

[0063] Ice water production function: When the first water pump 500 is started, the drinking water in the water tank 100 flows through the instant heater 1000. The drinking water transfers heat to the phase change cold storage material 210 in the cold storage chamber, thereby lowering the temperature of the drinking water. Finally, the drinking water changes from room temperature water to ice water and flows out through the first water outlet 400.

[0064] Room temperature water production function: When the second water pump 1200 is started, the drinking water in the water tank 100 flows through the second water pump 1200, then through the instant water heater 1000, and finally flows out through the second water outlet 1100.

[0065] Hot water production function: The second water pump 1200 starts and the instant heater 1000 starts; the drinking water in the water tank 100 flows through the second water pump 1200 and is then transported to the instant heater 1000. After being heated by the instant heater 1000, it finally flows out through the second water outlet 1100.
