[0029] The "plane" referred to in the present application is the "plane substantially parallel to the horizontal plane" in actual operation.

[0030] Reference Figure 1 , the train integrated water supply device provided by the embodiments of the present application includes a drinking water module 1 and a lavatory module 2, and the drinking water module 1 and the lavatory module 2 are of an integrated structure.

[0031] The drinking water module and the lavatory module can be pre-assembled in advance and subjected to tests such as functional tests, pipeline pressure maintenance, and insulation withstand voltage to ensure that the overall performance and structure of the module can operate normally.

[0032] In the train integrated water supply device, the lavatory module 2 includes a washbasin 4 and a water valve 3 arranged above the washbasin 4. Exemplarily, the water valve 3 can be an induction water valve, and the sensor and the water valve 3 are of an integrated structure. When washing hands, place the hand under the water valve 3, and the sensor is activated, and the water valve 3 discharges water. The setting of the induction water valve can achieve contactless automatic opening, which is hygienic and clean.

[0033] The water valve 3 can also be a mechanical switch type water valve, such as a lift type, a spiral type, etc., and the water valve 3 discharges water through manual operation. The embodiments of the present application do not limit this.

[0034] The drinking water module 1 includes a water purification and filtration component 13, a drinking water tank, and a concentrated water tank 12. The concentrated water outlet of the water purification and filtration component 13 is connected to the concentrated water tank 12, so that the concentrated water generated after filtration enters the concentrated water tank 12; the purified water outlet of the water purification and filtration component 13 is connected to the drinking water tank, so that the filtered purified water enters the drinking water tank.

[0035] Exemplarily, the water purification and filtration assembly 13 may include a composite PP cotton, activated carbon, and an RO reverse osmosis membrane. Of course, the water purification and filtration assembly 13 may further include other filtration structures based on the composite PP cotton, activated carbon, and RO reverse osmosis membrane, or the water purification and filtration assembly 13 includes other filtration structures, which are not limited in the embodiments of the present application.

[0036] The concentrated water tank 12 is connected to the water valve 3. The concentrated water tank 12 can supply the water valve 3 with wash water, enabling the concentrated water in the concentrated water tank 12 to be used for washing, and recycling the concentrated water generated after filtration.

[0037] The train integrated water supply device provided by the embodiments of the present application integrates the drinking water module 1 and the washing module 2 into an integrated structure, capable of providing drinking water and washing services in the same area, saving the interior space of the vehicle; at the same time, the concentrated water generated after filtration by the water purification and filtration assembly 13 in the drinking water module 1 is used for washing, recycling the filtered concentrated water, further saving water resources, and achieving the dual integration of the structures and functions of the drinking water module 1 and the washing module 2.

[0038] Reference Figure 2 , the drinking water tank includes a direct drinking water tank 10 and a hot water tank 11. The purified water filtered by the water purification and filtration assembly 13 enters the direct drinking water tank 10 and the hot water tank 11 respectively. The purified water in the direct drinking water tank 10 is available for passengers to drink, and the purified water in the hot water tank 11 can be heated to provide hot water for passengers to drink.

[0039] The hot water tank 11 includes a heating device for heating the water in the hot water tank 11.

[0040] The concentrated water generated by the filtration of the water purification and filtration assembly 13 enters the concentrated water tank 12. The concentrated water tank 12 is connected with a wash water pipe, and the concentrated water tank 12 is connected to the water valve 3 through the wash water pipe, enabling the concentrated water to flow out through the water valve 3 after passing through the wash water pipe for passengers to use for washing. Among them, the water in the wash water pipe is heated by a heat source, and the heated wash water can be directly provided through the water valve 3, thereby providing passengers with more comfortable wash water, avoiding the stimulation of the body caused by the wash water with too low temperature, and improving the riding experience of passengers.

[0041] In some embodiments, the wash water pipe can pass through the hot water tank 11, and the concentrated water in the wash water pipe can exchange heat with the hot water in the hot water tank 11, enabling the hot water in the hot water tank 11 to heat the concentrated water in the wash water pipe, so that the heated wash water can be provided through the water valve 3 for passengers to use. The heated wash water can be no more than 45°C. In this way, the heating device in the hot water tank 11 can also indirectly heat the wash water, eliminating the need for a separate heating device in the washing module.

[0042] In some other embodiments, a hot water pipe is connected to the hot water tank 11. The hot water pipe and the wash water pipe can be connected to the water valve 3 through a connector. The connector can be a three-way mixing valve, a four-way regulating valve, or other components capable of mixing the hot water in the hot water pipe with the concentrated water in the wash water pipe, so that the wash water with a suitable temperature after mixing the hot water and the concentrated water can be provided through the water valve 3 for passengers to use.

[0043] In some other embodiments, a heater is provided on the outer wall of the wash water pipe. The heater can heat the concentrated water flowing through the wash water pipe. For example, the heater includes a self-controlled heating trace wound around the outer wall of the wash water pipe, or the heater includes a heating sleeve, etc., so that the heated wash water can be provided through the water valve 3 for passengers to use.

[0044] Reference Figure 1 - Figure 2 , the drinking water module 1 further includes a water receiving panel 6. Operation buttons 7 are provided on the water receiving panel 6. Specifically, the operation buttons 7 can include a heating indicator light, a power indicator light, a ready indicator light, as well as a hot water button and a direct drinking water button. When the ready indicator light is on, it means that the hot water heating is completed and hot water can be taken. When a passenger needs to take hot water, press the hot water button in the operation buttons 7; when the power indicator light is on, it means that the medium voltage electricity of the heating device in the hot water tank is connected; when the heating indicator light is on, it means that the purified water in the hot water tank is being heated; when a passenger needs to take direct drinking water, directly press the direct drinking water button in the operation buttons 7. Press the operation buttons 7 to supply the hot water or direct drinking water required by the passenger through the drinking water outlet 8.

[0045] The drinking water module 1 further includes a water receiving tray 9. The water receiving tray 9 is located below the drinking water outlet 8 and is used to place a water receiving container. Specifically, the water receiving tray 9 is provided with drain holes and is of an under-counter basin structure. The drinking water that is not completely received by the water receiving container provided by the drinking water outlet 8 can be temporarily stored in the water receiving tray 9 through the drain holes, which is convenient for cleaning.

[0046] Reference Figure 1 - Figure 2 , the train integrated water supply device as a whole has an upper and lower cabinet structure. The upper water receiving panel 6 forms a double-door structure of the upper cabinet. A drinking water tank and a concentrated water tank 12 are provided behind the water receiving panel 6. The drinking water tank is located at the top of the drinking water outlet 8, and the concentrated water tank 12 is located at the top of the water valve 3.

[0047] The water purification and filtration component 13 is located below the plane where the water receiving tray 9 is located. A garbage bin 5 is provided on one side of the water purification and filtration component 13. A cabinet door on the same plane as the garbage bin 5 is provided outside the water purification and filtration component 13, so that the cabinet door of the water purification and filtration component 13 and the garbage bin 5 form a double-door structure of the lower cabinet.

[0048] In some embodiments, the drinking water tank, the drinking water outlet 8, the water receiving tray 9, and the water purification and filtration assembly 13 are distributed in sequence from top to bottom, and are all located on one side of the train integrated water supply device; the concentrated water tank 12, the water valve 3, the washbasin 4, and the trash can 5 are distributed in sequence from top to bottom, and are all located on the other side of the train integrated water supply device.

[0049] To improve the aesthetics, the board where the water receiving tray 9 is located is set at the same height as the board where the washbasin 4 is located, and they are of an integral structure.

[0050] The above structure realizes the structural integration of the drinking water module and the lavatory module of the train integrated water supply device, saving the interior space of the train.

[0051] In some embodiments, the lavatory water pipe is provided with a concentrated water tank outlet solenoid valve 19 and a warm water outlet solenoid valve 22. Among them, the concentrated water tank outlet solenoid valve 19 is closer to the outlet of the concentrated water tank 12 than the warm water outlet solenoid valve 22, and the warm water outlet solenoid valve 22 is closer to the water valve 3 than the concentrated water tank outlet solenoid valve 19. In this way, the distance between the warm water outlet solenoid valve 22 and the water valve 3 is shorter. After closing the warm water outlet solenoid valve 22, the water remaining in the lavatory water pipe from the warm water outlet solenoid valve 22 to the water valve 3 is less, which can reduce the dripping water of the water valve 3, or can avoid the water valve 3 from dripping water.

[0052] The concentrated water tank 12 is also connected with a concentrated water pipe. The concentrated water pipe connects the concentrated water outlet of the water purification and filtration assembly 13 and the concentrated water tank 12, and a concentrated water tank inlet solenoid valve 18 is provided on the concentrated water pipe; when the concentrated water generated after the water purification and filtration assembly 13 filters enters the concentrated water tank, the concentrated water tank inlet solenoid valve 18 opens. When warm water needs to be provided, the concentrated water tank outlet solenoid valve 19 opens, and the concentrated water flows into the lavatory water pipe, and then exchanges heat with the hot water in the hot water tank through the hot water tank. After that, the warm water outlet solenoid valve 22 opens, and the heated lavatory water flows out through the water valve 3.

[0053] A first liquid level sensor is also arranged in the concentrated water tank 12 to detect the liquid level in the concentrated water tank 12.

[0054] The train integrated water supply device further includes an electric control box 26. The electric control box 26 is located at the rear side of the water receiving panel 6, and the electric control box 26 is located below the concentrated water tank 12 and on the same side as the concentrated water tank 12. The electric control box 26 is electrically connected to the concentrated water tank outlet solenoid valve 19, the warm water outlet solenoid valve 22, the concentrated water tank inlet solenoid valve 18, and the first liquid level sensor to achieve overall control.

[0055] Refer to Figure 2 In this embodiment, the train integrated water supply device further includes:

[0056] The water inlet pipe is connected to the water inlet of the water purification and filtration assembly 13. The water inlet pipe is provided with a water inlet solenoid valve 14 and a booster pump 15. After taking water from the water tank, through the water inlet pipe, the water inlet solenoid valve 14 is opened, and after being pressurized by the booster pump 15, it enters the water purification and filtration assembly 13;

[0057] The first purified water pipe is communicated with the purified water outlet of the water purification and filtration assembly 13. The purified water filtered by the water purification and filtration assembly 13 enters the first purified water pipe. The first purified water pipe is provided with a TDS detector (Total Dissolved Solids, the concentration of total dissolved substances in water) and a check valve. The check valve is located between the TDS detector and the water purification and filtration assembly 13;

[0058] The second purified water pipe is connected to the first purified water pipe and the direct drinking water tank 10. The second purified water pipe is provided with a direct drinking water inlet solenoid valve 16. The purified water providing direct drinking water in the first purified water pipe enters the direct drinking water tank 10 through the second purified water pipe;

[0059] Both the first purified water pipe and the second purified water pipe are communicated with one end of the third purified water pipe. The other end of the third purified water pipe is communicated with the water inlet of the hot water tank 11. The third purified water pipe is provided with a hot water tank inlet solenoid valve 17. The purified water that needs to be heated in the first purified water pipe can enter the hot water tank 11 through the third purified water pipe; The first purified water pipe and the second purified water pipe can be of an integral structure, the first purified water pipe and the third purified water pipe can be of an integral structure, or the second purified water pipe and the third purified water pipe can be of an integral structure;

[0060] The fourth purified water pipe is communicated with the water outlet of the direct drinking water tank 10. The fourth purified water pipe is provided with a direct drinking water outlet solenoid valve 21. Among them, the fourth purified water pipe shares a section of pipe with the second purified water pipe and the fourth purified water pipe shares a section of pipe with the third purified water pipe. When the direct drinking water outlet solenoid valve 21 is opened, the direct drinking water flows out through the fourth purified water pipe;

[0061] The fifth purified water pipe is communicated with the water outlet of the hot water tank 11. The fifth purified water pipe is provided with a hot water tank outlet solenoid valve 20. When the hot water tank outlet solenoid valve 20 is opened, the hot water flows out through the fifth purified water pipe;

[0062] The sixth purified water pipe is connected to the fourth purified water pipe and the drinking water outlet 8, as well as the fifth purified water pipe and the drinking water outlet 8. The sixth purified water pipe is provided with a drinking water outlet solenoid valve 23. When receiving a hot water or direct drinking water connection signal, the drinking water outlet solenoid valve 23 opens, and the corresponding direct drinking water solenoid valve 21 or hot water tank outlet solenoid valve 20 for hot water or direct drinking water opens, and the required drinking water is provided through the drinking water outlet 8; the drinking water outlet solenoid valve 23 is close to the drinking water outlet 8. In this way, by closing the drinking water outlet solenoid valve 23, the water stored in the sixth purified water pipe from the drinking water outlet solenoid valve 23 to the drinking water outlet 8 is less, which can reduce the dripping water at the drinking water outlet 8 or avoid the dripping water at the drinking water outlet 8.

[0063] The second liquid level sensor is arranged in the direct drinking water tank 10 and is used for detecting the liquid level.

[0064] The third liquid level sensor is arranged in the hot water tank 11 and is used for detecting the liquid level.

[0065] The temperature probe 25 is arranged in the hot water tank 11 and is used for detecting the temperature; specifically, a heating pipe 24 and an over-temperature protection device are also arranged in the hot water tank 11, which are used for heating the purified water in the hot water tank 11 and providing over-temperature protection.

[0066] Among them, the inlet solenoid valve 14, the booster pump 15, the TDS detector, the direct drinking water inlet solenoid valve 16, the hot water tank inlet solenoid valve 17, the direct drinking water outlet solenoid valve 21, the hot water tank outlet solenoid valve 20, the drinking water outlet solenoid valve 23, the second liquid level sensor, the third liquid level sensor, the temperature probe 25, the heating pipe 24, and the over-temperature protection device are all electrically connected to the electric control box 26.

[0067] Reference Figure 3 , when the train integrated water supply equipment in this embodiment works, the inlet solenoid valve 13 opens, the drinking water module 1 takes water from the water tank through the water inlet pipe, and after being pressurized by the booster pump 15, it passes through the purified water filtration component 13. Among them, after the filtered purified water is detected to meet the standard by the TDS detection device, it is transported into the first purified water pipe. Then, the direct drinking water inlet solenoid valve 16 and the hot water tank inlet solenoid valve 17 open, and the purified water in the first purified water pipe is respectively transported into the direct drinking water tank 10 and the hot water tank 11 through the second purified water pipe and the third purified water pipe. When the TDS detection exceeds the standard, the concentrated water tank inlet solenoid valve 18 opens, and the concentrated water generated by the purified water filtration component 13 is transported into the concentrated water tank 12 through the concentrated water pipe.

[0068] The second liquid level sensor in the direct drinking water tank 10 and the first liquid level sensor in the hot water tank 11 detect the liquid level in real time. When the high liquid level is not activated, the booster pump 15 is started for water supply until the high liquid level is activated. After the second liquid level sensor in the hot water tank 11 detects that the high liquid level is activated, the temperature probe 25 is started to detect the water temperature in the hot water tank 11 at this time. When the water temperature is lower than 92 °C, the heating pipe 24 is started for heating. When the temperature probe 25 detects that the water temperature reaches 95 °C, the heating pipe 24 stops heating.

[0069] When the direct drinking water signal is received, the direct drinking water outlet solenoid valve 23 and the direct drinking water outlet solenoid valve 21 are opened, and the direct drinking water is transported to the direct drinking water outlet 8 through the fourth water purification pipe and the sixth water purification pipe to provide direct drinking water; when the hot water signal is received, it is detected whether the water temperature reaches 92 °C. When the water temperature reaches 92 °C, the direct drinking water outlet solenoid valve 23 and the hot water tank outlet solenoid valve 20 are opened, and the heated drinking water is transported to the direct drinking water outlet 8 through the fifth water purification pipe and the sixth water purification pipe to provide hot water.

[0070] When the water valve 3 start signal is received, the concentrated water tank outlet solenoid valve 19 and the warm water outlet solenoid valve 22 are opened, and the wash water is transported from the concentrated water tank 12 to the water valve through the wash water pipe to provide wash water. Thus, the concentrated water in the concentrated water tank 12 can be used for washing, saving water resources.

[0071] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
