[0019] Please see Figures 1 to 2 , Figure 1 This is an installation diagram illustrating the specific application of the wastewater recycling system for a direct drinking water machine provided in this embodiment of the invention. The wastewater recycling system includes a water storage tank 11 and a booster pump 12. The inlet of the water storage tank 11 is connected to the direct drinking water machine 20 via a wastewater pipe 13. The outlet of the water storage tank 11 is connected to an outlet pipe 14, on which the booster pump 12 is mounted. The outlet of the booster pump 12 is equipped with a three-way valve. The first end of the three-way valve is connected to the outlet of the water storage tank 11 via the outlet pipe 14. The second end of the three-way valve is connected to a ground water device 31 via a first outlet branch pipe 15. The third end of the three-way valve is connected to a basement water device 32 via a second outlet branch pipe 16. The power input of the booster pump 12 is connected to a power source via a remote switch module 17.

[0020] in, Figure 1The arrows indicate the flow direction of wastewater. The power supply can be mains electricity. The inlet of the water storage tank 11 is connected to the drain pipe of the drinking water machine 20 via the wastewater pipe 13. The drain pipe of the drinking water machine 20 is used to discharge wastewater, which is concentrated water produced by the drinking water machine 20. The concentrated water produced by the drinking water machine 20 is transferred to the water storage tank 11 for collection via the wastewater pipe 13. The second end of the three-way valve is connected to one end of the first outlet branch pipe 15, and the other end of the first outlet branch pipe 15 is connected to the ground water device 31. The third end of the three-way valve is connected to one end of the second outlet branch pipe 16, and the other end of the second outlet branch pipe 16 is connected to the basement water device 32. The ground water device 31 refers to water devices located on the ground floor or above, including green belt sprinklers, toilet flushing devices, or handwashing sink faucets. The basement water device 32 refers to water devices located below the ground floor, including toilet flushing devices, handwashing sink faucets, or cleaning water faucets. Various faucets may be equipped with locking valves. Wastewater is diverted and reused via a three-way valve, expanding its applications, improving utilization efficiency, and saving water. This system is suitable for wastewater reuse in drinking water dispensers in communities, hospitals, residences, or schools. The water storage tank 11 can be located on the basement level to avoid the impact of external weather conditions and to make efficient use of floor space. The wastewater recycling system for the direct drinking water machine uses a wastewater pipe 13 connected to the inlet of the water storage tank 11 and an outlet pipe 14 connected to the outlet of the water storage tank 11, which is equipped with a booster pump 12. The outlet of the booster pump 12 is equipped with a three-way valve, one end of which is connected to the ground water device 31 through a first outlet branch pipe 15 and the other end of which is connected to the basement water device 32 through a second outlet branch pipe 16. This allows for the diversion and reuse of wastewater collected by the direct drinking water machine 20 from the water storage tank 12 through the wastewater pipe 13. The system can distribute the wastewater as needed, expand the uses of wastewater, improve wastewater utilization, and save water. Furthermore, the power input of the booster pump 12 is connected to a power source through a remote switch module 17, allowing for remote control of the start and stop of the booster pump 12 using a smart terminal. The system can also collect the working information of the booster pump 12. This system features high automation, reduces manual input, and lowers the frequency of manual intervention. Wastewater recycling can be achieved simply by controlling the operation of the booster pump 12, simplifying the wastewater recycling operation and improving management efficiency.

[0021] Preferably, the wastewater pipe 13, the water outlet pipe 14, the first water outlet branch pipe 15 and the second water outlet branch pipe 16 are all made of PPR (polypropylene type III) pipe.

[0022] Specifically, in this embodiment, the remote switch module 17 includes a wireless remote controller 171 and a contactor 172. The wireless remote controller 171 is connected to the coil of the contactor 172, and the power input terminal of the booster pump 12 is connected to the power supply through the contacts of the contactor 172. The wireless remote controller 171 can wirelessly connect to a smart terminal to receive commands from the user via an app or mini-program installed on the smart terminal to control the start and stop of the booster pump 12. Based on the received commands, the wireless remote controller 171 controls the energization and de-energization of the coil of the contactor 172, thereby controlling the contacts of the contactor 172 to perform corresponding actions, connecting or disconnecting the power supply to the power input terminal of the booster pump 12, thus achieving start and stop control of the booster pump 12. The wireless remote controller 171 can be connected to the booster pump 12 to collect the operating information of the booster pump 12 and wirelessly transmit it to the smart terminal. The operating information includes energy consumption metering and operating status, including running time and output pressure. The smart terminal includes smartphones, tablets, and / or laptops, and other electronic devices with wireless communication capabilities.

[0023] Of course, in some embodiments, the remote switch module 17 includes a wireless remote controller 171 and a switch. The control terminal of the switch is connected to the wireless remote controller 171, and the power input terminal of the booster pump 12 is connected to the power supply through the contacts of the switch. The switch is turned on and off by the wireless remote controller 171, thereby connecting or disconnecting the power supply to the power input terminal of the booster pump 12 and realizing the start and stop control of the booster pump 12.

[0024] Specifically, the wireless remote controller 171 includes a controller and a 4G communication module electrically connected to the controller. The controller is connected to the coil of the contactor 172. The 4G communication module transmits received instructions from the smart terminal to the controller. The controller controls the energization of the coil of the contactor 172 according to the received instructions. The controller can be connected to the booster pump 12 to collect the operating information of the booster pump 12, and the operating period of the booster pump 12 can be set through the controller. The 4G communication module can transmit data based on the MQTT protocol. Using a 4G communication module can eliminate the dependence on traditional Wi-Fi communication, improve the stability of wireless communication, and realize stable remote control.

[0025] Preferably, in this embodiment, the booster pump 12 is equipped with a pressure sensor to collect the output pressure of the booster pump. By setting the pressure sensor, the output pressure of the booster pump 12 can be collected. By controlling the output pressure of the booster pump 12, wastewater can be allocated as needed, avoiding the energy waste of traditional fixed pressure systems. The normal operating range of the booster pump's output pressure can be set to 0–0.5 MPa. When the output pressure of the booster pump 12 is 0.1–0.2 MPa, the wastewater can be controlled to flow to the underground water supply device 32. When the output pressure of the booster pump 12 is 0.3–0.5 MPa, the wastewater can be controlled to flow to the surface water supply device 31. The wireless remote controller 171 is connected to the booster pump 12 to determine whether the booster pump 12 is working normally based on the output pressure detected by the pressure sensor. When the output pressure of the booster pump 12 exceeds the maximum value of the set normal operating range, the booster pump 12 can be controlled to stop working. The controller can also adjust the operation of the booster pump 12 based on the detected output pressure, achieving real-time pressure regulation.

[0026] Specifically, in this embodiment, a float valve 18 is provided in the water storage tank 11. The float of the float valve 18 is placed inside the water storage tank 11, and the valve body of the float valve 18 is connected to the inlet of the water storage tank 11. The float of the float valve 18 moves with the water level of the wastewater in the water storage tank 11, thereby driving the linkage of the float valve 18 connected to the float to move. The movement of the linkage controls the opening and closing of the inlet of the water storage tank 11 by the valve body of the float valve 18, thereby controlling the start and stop of wastewater collection, realizing the control of wastewater collection based on the water level of the water storage tank 11. When the water level rises, the float moves upward with the water level, driving the linkage to move, which in turn drives the valve body to move. When the water level reaches the threshold, the linkage drives the valve body to close the inlet, stopping wastewater collection. When the water level drops, the float moves downward with the water level, driving the linkage to move, which in turn drives the valve body to open the inlet, and wastewater flows into the water storage tank 11, initiating wastewater collection.

[0027] Specifically, in this embodiment, the wastewater pipe 13 is equipped with an overflow three-way valve. The overflow three-way valve is T-shaped, with its opposite ends connected to the wastewater pipe 13. The vertical end of the overflow three-way valve is connected to the rainwater drainage network 40 through an overflow pipe 19. The vertical end of the overflow three-way valve refers to the end perpendicular to the opposite ends of the T-shaped overflow three-way valve. Through the cooperation of the float valve 18 and the overflow three-way valve, when the water level of the wastewater collected in the water storage tank 11 reaches the threshold and the float valve 18 closes the inlet, the vertical end of the overflow three-way valve is controlled to open while the opposite ends of the overflow three-way valve are closed. This automatically switches the flow of wastewater into the overflow pipe 19 and discharges it into the municipal rainwater drainage network 40, eliminating the need for manual monitoring and preventing the risk of overflow from the water storage tank 11. When the water level of the wastewater collected in the water storage tank 11 does not reach the threshold and the inlet is open, the opposite ends of the overflow three-way valve are opened and the vertical end of the overflow three-way valve is closed, so that the wastewater in the wastewater pipe 13 can flow normally into the water storage tank.

[0028] Specifically, the overflow pipe 19 is equipped with a one-way valve to prevent water from the rainwater drainage network 40 from flowing through the overflow pipe 19 to the wastewater pipe. When the vertical end of the overflow three-way valve is open, the one-way valve is controlled to open so that the wastewater from the drinking water machine 20 flows through the wastewater pipe 13 and the overflow pipe 19 to the rainwater drainage network 40. When the vertical end of the overflow three-way valve is closed, the one-way valve is controlled to close. The elevation of the overflow pipe 19 entering the municipal rainwater drainage network 40 is higher than the elevation of the horizontal section of the wastewater pipe 13 flowing to the water storage tank 11.

[0029] Specifically, in this embodiment, pressure sensors for detecting the pressure in each pipe can be installed on the wastewater pipe 13, the outlet pipe 14, the first outlet branch pipe 15, and the second outlet branch pipe 16. By detecting whether the pressure in the corresponding pipe reaches the preset pressure value corresponding to each working state, if it exceeds the preset pressure value corresponding to the current working state, the booster pump is controlled to stop working; if it is lower than the preset pressure value corresponding to the current working state, the booster pump is controlled to work, thereby achieving a pressure stabilization function and ensuring optimal system safety and energy efficiency.

[0030] Preferably, the bottom of the water storage tank 11 is provided with a drainage channel with a valve, which can be opened according to a preset time period to open the drainage channel and discharge the wastewater from the water storage tank 11. Since the sediment settles at the bottom of the water storage tank 11 under the action of gravity, most of the sediment can be discharged with the wastewater when the drainage channel at the bottom is open, realizing the periodic cleaning of the sediment. The top of the water storage tank 11 may have an opening and a sealing cover on the opening.

[0031] Specifically, the water outlet is located at the lower end of the water storage tank 11, and a stainless steel frame is installed on the outside of the water storage tank 11. The stainless steel frame reinforces the water storage tank 11, making it more robust, stable, environmentally friendly, and durable.

[0032] Preferably, the water storage tank 11 has a capacity of 500L, which is suitable for a direct drinking water machine 20 that generates 30L of wastewater per day.

[0033] In summary, the wastewater recycling system for direct drinking water machines of this utility model is designed to divert and reuse the wastewater collected from the water storage tank via a wastewater pipe connected to the inlet and an outlet pipe equipped with a booster pump connected to the outlet. The booster pump's outlet is equipped with a three-way valve, one end connected to a ground-level water supply system via a first outlet branch pipe and the other end connected to a basement water supply system via a second outlet branch pipe. This allows for the distribution of wastewater from the direct drinking water machine, which can be distributed as needed, expanding the uses of wastewater, improving wastewater utilization, and achieving water conservation. Furthermore, the booster pump's power input is connected to a power source via a remote switch module, enabling remote control of the booster pump's start and stop via a smart terminal. The system also collects the booster pump's operating information, resulting in high automation, reduced manual labor, and simplified wastewater recycling operations by controlling the booster pump's operation.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
