Abstract
Description
Technical Field

[0002] As people's demands for quality of life increase, water purifiers are becoming more and more popular and widely used. Improving the hot water supply capacity of water purifiers has become a key aspect of enhancing user experience.
[0003] In related technologies, hot water supply is often achieved by using heating modules and vacuum storage tanks. However, in these technologies, as the amount of hot water released increases, the amount of cold water accumulating in the lower part of the tank also increases. This makes it impossible to fully utilize the heat in the tank, resulting in an inability to achieve a large flow rate of hot water at each stage. Furthermore, it is impossible to adjust the water flow rate based on the relationship between the current water temperature and the outlet water temperature to meet user needs, leading to a sharp drop in the water flow rate, low continuity of hot water supply, and a poor user experience.

[0026] Figure 1 This is a schematic diagram of a water purifier proposed in an embodiment of this application. Figure 1 ,like Figure 1 As shown, the system includes a water purification module 1, a vacuum heat storage tank 2, a mixing chamber 3, and a heating module 4. The outlet of the water purification module 1 is connected to the inlet of the vacuum heat storage tank 2, and the outlet of the vacuum heat storage tank 2 is connected to the inlet of the heating module 4. One outlet of the heating module 4 is connected to the inlet of the vacuum heat storage tank 2, and the other outlet is connected to the hot water outlet 5. The mixing chamber 3 is located on the water path connecting the vacuum heat storage tank 2 and the heating module 4. One inlet of the mixing chamber 3 is connected to the outlet of the vacuum heat storage tank 2, and the other inlet of the mixing chamber 3 is connected to the outlet of the water purification module 1. The outlet of the mixing chamber 3 is connected to the inlet of the heating module 4.
[0027] In this embodiment, when no one is using water, the cold water treated by the water purification module 1 is injected into the vacuum heat storage tank 2 through the water passage connecting the outlet of the water purification module 1 and the inlet of the vacuum heat storage tank 2. The cold water in the vacuum heat storage tank 2 is heated through the water passage connecting the outlet of the vacuum heat storage tank 2 and the inlet of the heating module 4. Then, the heated hot water is injected into the vacuum heat storage tank 2 through the water passage connecting the outlet of the heating module 4 and the inlet of the vacuum heat storage tank 2.
[0028] In this embodiment, when the water purifier dispenses hot water, the cold water processed by the water purification module 1 is injected into the mixing chamber 3 through a water passage connecting the outlet of the water purification module 1 to one inlet of the mixing chamber 3. The hot water in the vacuum heat storage tank 2 is injected into the mixing chamber 3 through a water passage connecting the outlet of the vacuum heat storage tank 2 to another inlet of the mixing chamber 3. The mixed water is then heated and released through a water passage connecting the outlet of the mixing chamber 3 to the inlet of the heating module 4.
[0029] In some possible embodiments, a first temperature sensor 6 is installed on the water path connecting the outlet of the mixing chamber 3 and the inlet of the heating module 4; a second temperature sensor 7 is installed on the outlet of the heating module 4; and a third temperature sensor 8 is installed on the water path connecting one inlet of the mixing chamber 3 and the outlet of the vacuum storage tank 2. The first temperature sensor 6 is used to measure the temperature of the mixed water in the mixing chamber 3, the second temperature sensor 7 is used to measure the temperature of the hot water released by the heating module 4, and the third temperature sensor 8 is used to measure the temperature of the hot water in the vacuum storage tank 2.
[0030] In some possible embodiments, the outlet of the heating module 4 is connected to the inlet of the vacuum storage tank 2 via the hot water return valve 9, and to the hot water outlet 5 via the hot water outlet valve 9.
[0031] In this embodiment, when the water purifier dispenses hot water, the cold water processed by the water purification module 1 is supplied to the vacuum heat storage tank 2 through the water path connecting the outlet of the water purification module 1 and the inlet of the vacuum heat storage tank 2. Based on the temperature of the hot water in the vacuum heat storage tank 2 obtained by the third temperature sensor 8, when the temperature of the hot water in the vacuum heat storage tank 2 is lower than the preset storage temperature, the hot water in the vacuum heat storage tank 2 is drawn out and reheated through the water path connecting the outlet of the vacuum heat storage tank 2 and the inlet of the heating module 4, and the water path connecting the outlet of the heating module 4 and the inlet of the vacuum heat storage tank 2. The heated hot water is then returned to the vacuum heat storage tank 2 through the hot water return valve 9 set on the water path connecting the outlet of the heating module 4 and the inlet of the vacuum heat storage tank 2.
[0032] In some possible embodiments, the water purifier also includes a hot water pump 11, which is disposed on the water line connecting the vacuum storage tank 2 and the heating module 4.
[0033] In this embodiment, when no one is using the water, if the temperature of the hot water in the vacuum storage tank 2 measured by the third temperature sensor 8 is lower than the preset storage temperature, the hot water in the vacuum storage tank 2 is drawn to the heating module 4 for heating through the water path connecting the outlet of the vacuum storage tank 2 and the inlet of the heating module 4, and through the hot water pump 11 installed on the water path connecting the vacuum storage tank 2 and the heating module 4. The heated hot water is then returned to the vacuum storage tank 2 through the water path connecting the outlet of the heating module 4 and the inlet of the vacuum storage tank 2, and through the hot water return valve 9 installed on the water path connecting the outlet of the heating module 4 and the inlet of the vacuum storage tank 2, so that the hot water in the vacuum storage tank 2 is not lower than the preset storage temperature.
[0034] In some possible embodiments, the outlet of the water purification module 1 is connected to the inlet of the vacuum heat storage tank 2 and another inlet of the mixing chamber 3 via the flow regulating valve 12.
[0035] In this embodiment, the flow regulating valve 12 is used to control the flow rate of the cold water discharged from the outlet of the water purification module 1 into the water path connecting the outlet of the water purification module 1 and the inlet of the vacuum heat storage tank 2, and the water path connecting the outlet of the water purification module 1 and another inlet of the mixing chamber 3.
[0036] In some possible embodiments, the outlet of the vacuum heat storage tank 2 is also connected to the exhaust outlet 14 via a safety valve 13.
[0037] In this embodiment, the safety valve 13 is used to discharge the air inside the vacuum heat storage tank 2. Specifically, when the pressure inside the vacuum heat storage tank 2 is high, the safety valve 13 will automatically release pressure to prevent the vacuum heat storage tank 2 from exploding.
[0038] In some possible embodiments, the outlet of the water purification module 1 is also connected to the cold water outlet 16 via the cold water valve 15.
[0039] In this embodiment of the application, when the water purifier dispenses cold water, the flow regulating valve 12 is controlled so that all the cold water discharged from the outlet of the water purification module 1 is discharged through the water passage connecting the outlet of the water purification module 1, the cold water valve 15, and the cold water outlet 16.

Figure 2 ,like Figure 2 As shown, the outlet of heating module 4 is connected to the inlet of vacuum storage tank 2 via check valve 17, to the drain pipe 19 via drain valve 18, and to the hot and cold water outlet 21 via hot and cold water outlet valve 20. The water path connected to drain valve 18 and drain pipe 19 is used to drain excess hot or cold water from the water path connected to the outlet of heating module 4 and the hot and cold water outlet 21, to prevent scalding or excessively low water temperature and to ensure a constant outlet water temperature.
[0041] In this embodiment, when the water purifier dispenses cold water, the flow regulating valve 12 is controlled so that all the cold water discharged from the outlet of the water purification module 1 is discharged through the water passage connecting the cold and hot water outlet valve 20 and the cold and hot water outlet 21 via the outlet of the water purification module 1.

Figure 3 ,like Figure 3 As shown, the outlet of the water purification module 1 is connected to the cold water outlet 16 via a one-way valve 17. The water path connecting the outlet of the water purification module 1 and the cold water outlet 16 is on the water path connecting the outlet of the heating module 4 and the inlet of the vacuum heat storage tank 2.
[0043] In this embodiment, the water path connecting the outlet of the water purification module 1 and the cold water outlet 16 is connected to the water path connecting the outlet of the heating module 4 and the inlet of the vacuum heat storage tank 2, eliminating unnecessary pipes and saving costs.
[0044] Figure 4 This is a schematic diagram of a water purifier proposed in an embodiment of this application. Figure 4 ,like Figure 4As shown, the outlet of the water purification module 1 is connected to the hot and cold water outlet 21 via the hot water return valve 9 and the hot and cold water outlet valve 20. The water circuit connecting the outlet of the heating module 4 to the inlet of the vacuum heat storage tank 2 via the hot water return valve 9 is set in the water circuit connecting the outlet of the water purification module 1 and the hot and cold water outlet 21.
[0045] In this embodiment, the water outlet of the water purification module 1 is connected to the cold and hot water outlet 21 via the hot water return valve 9 and the cold and hot water outlet valve 20 to release the cold water treated by the water purification module 1. The water outlet of the heating module 4 is connected to the water inlet of the vacuum heat storage tank 2 via the hot water return valve 9 to circulate and heat the hot water in the vacuum heat storage tank 2. Combining the two water paths can save pipes and reduce costs.
