[0089] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0090] The following combination Figures 1-4 , describing the embodiments of the present utility model.

[0091] According to an embodiment of the present invention, on the one hand, a hot water outlet assembly is provided, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it includes: a purified water receiving pipeline 1, a normal temperature water pipeline 2, a heating pipeline 4, a first valve body 6, a second valve body 7, a heating device 8 and a regulating device.

[0092] The clean water inlet pipeline 1 is suitable for receiving clean water, and the normal temperature water pipeline 2 and the heating pipeline 4 are respectively connected to the clean water inlet pipeline 1. The end of the normal temperature water pipeline 2 is provided with a normal temperature water outlet 3, and the end of the heating pipeline 4 is provided with a hot water outlet 5. The normal temperature water outlet 3 and the hot water outlet 5 are both connected to the water outlet 13; the first valve body 6 is provided on the normal temperature water pipeline 2, and when the first valve body 6 is opened, the clean water is suitable for being output from the normal temperature water outlet 3; the second valve body 7 is provided on the heating pipeline 4; the heating device 8 is provided on the heating pipeline 4 and is located downstream of the second valve body 7. When the second valve body 7 is opened, the clean water is suitable for flowing to the heating device 8 for heating, and the heated clean water is suitable for being output from the hot water outlet 5; the regulating device is provided on the heating pipeline 4 and is located upstream of the heating device 8. The regulating device is suitable for regulating the water supply of the heating pipeline 4.

[0093] In the above embodiment, purified water is obtained from the water purification system upstream of the purified water receiving pipe 1. After the purified water is connected to the purified water, the purified water receiving pipe 1 can be passed into the downstream normal temperature water pipe 2 and the heating pipe 4; when normal temperature water is needed, the first valve body 6 is opened, and the purified water at normal temperature is output from the normal temperature water outlet 3 at the end of the normal temperature water pipe 2, and the user can take normal temperature water; when hot water is needed, the second valve body 7 is opened, and the purified water at normal temperature is converted into hot water after being heated by the heating device 8, and the hot water is output from the hot water outlet 5 at the end of the heating pipe 4, and the user can take hot water; normal temperature water and hot water are respectively obtained through the separate normal temperature water pipe 2 and heating pipe 4. The two sections of the pipes are independent of each other and do not affect each other. A regulating device is provided to adjust the water supply of the heating pipe 4 so that the user can take hot water of different temperatures as needed, thereby solving the problem of hot water temperature dropping caused by the mixing of hot water and cold water.

[0094] Specifically, if Figure 1 、 Figure 2 As shown, the heating device 8 is a circular pipe structure as a whole. When the clean water at room temperature flows through the heating device 8, it exchanges heat with the heating element in the heating device 8, thereby realizing the conversion of clean water at room temperature into hot water.

[0095] Furthermore, the heating element is specifically a heating wire, an eddy current coil, etc.

[0096] Further, if Figure 1 、 Figure 2 As shown, the first valve body 6 and the second valve body 7 are used to control the opening and closing of the normal-temperature water pipeline 2 and the heating pipeline 4, respectively. When normal-temperature water is required, the first valve body 6 is opened while the second valve body 7 is kept closed; when hot water is required, the second valve body 7 is opened while the first valve body 6 is kept closed. By using the first valve body 6 and the second valve body 7 to control the opening and closing of the normal-temperature water pipeline 2 and the heating pipeline 4, respectively, if one valve body needs to be repaired or replaced, the other valve body can still maintain normal operation.

[0097] Further, if Figure 1 、 Figure 2 As shown, the first valve body 6 and the second valve body 7 can be electrically controlled by a controller, or manually controlled using a manual valve.

[0098] Further, if Figure 1 、 Figure 2As shown, this embodiment does not limit the specific configuration and adjustment method of the regulating device. The regulating device regulates the water supply of the heating pipeline 4, that is, regulates the flow rate of unheated purified water in the heating pipeline 4. In one embodiment, the regulating device can be configured as a pump body to regulate the flow rate of unheated purified water in the heating pipeline 4. In another embodiment, the regulating device can regulate the flow rate of unheated purified water in the heating pipeline 4 by adjusting the opening size of the second valve body 7.

[0099] Further, if Figure 1 、 Figure 2 As shown, a first TDS probe 14 is provided in the purified water receiving pipeline 1 , and the first TDS probe 14 is used to detect the purity of the purified water entering the purified water receiving pipeline 1 to ensure the quality of the purified water.

[0100] Further, if Figure 1 、 Figure 2 As shown, a first pulse counter 15 is further provided in the purified water receiving pipeline 1 .

[0101] Further, if Figure 1 、 Figure 2 As shown, a water outlet 13 is provided so that the normal temperature water outlet 3 can output normal temperature water through the water outlet 13, and the hot water outlet 5 can output hot water through the water outlet 13. The water outlet 13 is provided at the end of the normal temperature water pipe 2 and the heating pipe 4, and is fixedly connected to the normal temperature water outlet 3 and the hot water outlet 5 so that the user can take water as needed.

[0102] In some embodiments, as Figure 1 、 Figure 2 As shown, the hot and cold water outlet assembly further includes: a temperature detection device 9.

[0103] The temperature detection device 9 is provided in the heating pipeline 4 and is located downstream of the heating device 8. The temperature detection device 9 is suitable for detecting the temperature of the purified water after being heated by the heating device 8 and sending temperature information.

[0104] In the above embodiment, the temperature detecting device 9 can detect the temperature of the purified water after being heated by the heating device 8 and send the temperature information of the relevant water temperature, so as to subsequently adjust the water supply of the heating pipeline 4.

[0105] Specifically, if Figure 1 、 Figure 2 As shown, the temperature detection device 9 can be set as a temperature sensing package. The temperature detection device 9 is located in the heating pipeline 4 near the water outlet of the heating device 8, so as to detect the temperature of the hot water generated after being heated by the heating device 8 at the first time, thereby improving the accuracy of temperature measurement.

[0106] In some embodiments, as Figure 1 、 Figure 2、 Figure 3 As shown, the hot and cold water outlet assembly further includes a controller 10 .

[0107] The controller 10 is communicatively connected to the temperature detection device 9 and the regulating device respectively. The controller 10 is suitable for controlling the regulating device according to the temperature information, and regulating the water supply of the heating pipeline 4 through the regulating device to generate multi-temperature hot water in the heating pipeline 4.

[0108] In the above embodiment, the controller 10 is used in conjunction with the regulating device and the temperature detection device 9 to regulate the water supply in the heating pipeline 4, that is, the unheated clean water flow, and change the water temperature of the hot water output from the hot water outlet 5 in the heating pipeline 4, thereby meeting the user's demand for obtaining hot water in multiple temperature ranges and improving the functional diversity of the hot and cold water outlet components and the water purifier.

[0109] Specifically, if Figure 1 、 Figure 2 、 Figure 3 As shown, when the temperature of the heated purified water is too high and higher than the hot water temperature required by the user, the controller 10 controls the regulating device to increase the flow rate of unheated purified water according to the temperature information, thereby reducing the temperature of the hot water output from the hot water outlet 5 while the heating power of the heating device 8 remains unchanged; when the temperature of the heated purified water is too low and lower than the hot water temperature required by the user, the controller 10 controls the regulating device to reduce the flow rate of unheated purified water according to the temperature information, thereby increasing the temperature of the hot water output from the hot water outlet 5 while the heating power of the heating device 8 remains unchanged.

[0110] Further, if Figure 1 、 Figure 2 As shown, the temperature detection device 9 is located near the water outlet of the heating device 8 and can accurately measure the water temperature, thereby accurately feeding back to the controller 10 so that the regulating device can accurately adjust the unheated clean water flow in the heating pipeline 4 according to the water temperature required by the user.

[0111] In some embodiments, as Figure 1 、 Figure 2 As shown, the regulating device includes a self-priming water pump 11 , which is provided in the heating pipeline 4 and downstream of the second valve body 7 . The self-priming water pump 11 is suitable for regulating the water supply in the heating pipeline 4 .

[0112] In the above embodiment, the regulating device is provided as a self-priming water pump 11 located downstream of the second valve body 7 , thereby achieving a flow regulation function on the unheated purified water in the heating pipeline 4 .

[0113] Specifically, if Figure 1 、 Figure 2As shown, the self-priming water pump 11 has been filled with unheated clean water in the pump casing before starting; after the self-priming water pump 11 is started, the impeller rotates at high speed to make the water in the impeller groove flow to the volute, and at this time a vacuum is formed at the inlet of the self-priming water pump 11, so that the water inlet check valve is opened, and the air in the heating pipe 4 is sucked into the self-priming water pump 11 and reaches the outer edge through the impeller groove; through repeated circulation, the air sucked into the heating pipe 4 is gradually exhausted to form a complete vacuum environment, and the principle of atmospheric pressure is used to make the unheated clean water enter the self-priming water pump 11 for pumping, thereby completing the self-priming operation.

[0114] In some embodiments, as Figure 1 、 Figure 2 As shown, the regulating device further includes a zero-pressure valve 12 , which is provided in the heating pipeline 4 and upstream of the self-priming water pump 11 . The zero-pressure valve 12 is suitable for reducing the water pressure in the heating pipeline 4 to zero.

[0115] In the above embodiment, a zero-pressure valve 12 is provided in the heating pipeline 4, thereby cooperating with the self-priming water pump 11 to reduce the water pressure in the heating pipeline 4 to zero, ensuring that a vacuum is formed at the inlet of the self-priming water pump 11, and ensuring that the self-priming water pump 11 utilizes the atmospheric pressure to pump the unheated clean water.

[0116] Specifically, if Figure 1 、 Figure 2 As shown, after the self-priming water pump 11 is started, the impeller needs to rotate at high speed to make the water in the impeller groove flow to the volute, so that a vacuum environment is formed at the inlet of the self-priming water pump 11; at this time, if the pump casing of the self-priming water pump 11 is not filled with unheated clean water before starting, the pressure reduction at the inlet of the self-priming water pump 11 will not be complete, and a vacuum environment cannot be formed. Therefore, the pressure reducing effect of the zero-pressure valve 12 is used to reduce the water pressure in the heating pipeline 4 to zero, so that the self-priming water pump 11 can normally pump the unheated clean water.

[0117] Further, if Figure 1 、 Figure 2 As shown, the zero-pressure valve 12 can also ensure that the pressure in the water delivery system remains within a certain range, preventing system failures caused by excessively high or low pressure. The self-priming water pump 11 operates in conjunction with the zero-pressure valve 12 to achieve the self-priming function of the self-priming water pump 11 and ensure the stable operation of the water delivery system, thereby improving safety.

[0118] In some embodiments, as Figure 1 、 Figure 2 As shown, the first valve body 6 is configured as an on-off solenoid valve, and / or the second valve body 7 is configured as an on-off solenoid valve.

[0119] Specifically, only the first valve body 6 may be configured as an on-off solenoid valve, or only the second valve body 7 may be configured as an on-off solenoid valve, or both the first valve body 6 and the second valve body 7 may be configured as on-off solenoid valves.

[0120] Further, as an alternative embodiment, the first valve body 6 and the second valve body 7 can be configured as manual valves.

[0121] According to an embodiment of the present invention, on the other hand, a water purifier is also provided, such as Figure 1 、 Figure 4 As shown, it includes: a whole machine body 200 and a hot and cold water outlet assembly 100 of any of the above embodiments.

[0122] The main body 200 of the whole machine is suitable for receiving tap water and converting tap water into purified water. The main body 200 of the whole machine is provided with a purified water delivery pipeline 2001 suitable for outputting purified water; the purified water receiving pipeline 1 of the hot and cold water outlet assembly 100 is connected to the purified water delivery pipeline 2001.

[0123] In the above embodiment, the main body 200 of the machine is used to convert tap water into purified water, and the purified water is output to the purified water supply pipeline 2001 of the hot and cold water outlet assembly 100 through the purified water supply pipeline 2001, thereby providing the hot and cold water outlet assembly 100 with purified water for preparing normal temperature water and hot water.

[0124] Specifically, if Figure 1 、 Figure 4 As shown, the main body 200 includes a composite filter element, a reverse osmosis membrane filter element and several pipelines.

[0125] In some embodiments, as Figure 1 、 Figure 4 As shown, the main body 200 of the machine includes: a composite filter element, a reverse osmosis membrane filter element 2004, a raw water inlet pipeline 2005, a first water production pipeline 2006, a second water production pipeline 2007 and a concentrated water outlet pipeline 2008.

[0126] The composite filter element includes a pre-PAC filter element 2002 and a post-activated carbon filter element 2003; a raw water inlet pipeline 2005 is suitable for connecting to tap water, and the raw water inlet pipeline 2005 is connected to the water inlet of the pre-PAC filter element 2002; a first water production pipeline 2006 is connected between the water outlet of the pre-PAC filter element 2002 and the water inlet of the reverse osmosis membrane filter element 2004; a second water production pipeline 2007 is connected between the water outlet of the reverse osmosis membrane filter element 2004 and the water inlet of the post-activated carbon filter element 2003; a concentrated water outlet pipeline 2008 is suitable for discharging concentrated water, and the concentrated water outlet pipeline 2008 is connected to the water outlet of the post-activated carbon filter element 2003; the water outlet of the post-activated carbon filter element 2003 is connected to the purified water supply pipeline 2001.

[0127] In the above embodiment, the tap water is filtered and purified multiple times by the PAC filter element 2002, the reverse osmosis membrane filter element 2004 and the post-activated carbon filter element 2003 in the composite filter element to achieve the preparation of purified water.

[0128] Specifically, if Figure 1 、 Figure 4 As shown, tap water is received through the raw water inlet pipe 2005, then filtered once through the pre-PAC filter element 2002, and then transported through the first water production pipe 2006 to the reverse osmosis membrane filter element 2004 for secondary filtration. At this time, some of the concentrated water containing impurities is discharged as wastewater through the concentrated water outlet pipe 2008, while the remaining water is transported through the second water production pipe 2007 to the post-activated carbon filter element 2003 for tertiary filtration, ultimately completing the preparation of purified water, which is then output through the purified water delivery pipe 2001 for subsequent use. In this embodiment, the purified water delivery pipe 2001 is connected to the purified water inlet pipe 1 of the hot and cold water outlet assembly 100.
