[0002] Integrated water equipment is an integrated household appliance mainly composed of a heating unit and a water purification unit. It can not only provide domestic water but also drinking water.

[0003] Existing integrated water treatment systems typically require a water purification unit to filter and purify domestic raw water. However, this filtration and purification process generates wastewater. Therefore, to discharge this wastewater, existing integrated water treatment systems typically include a wastewater tank, a drain outlet, and a wastewater pump. This allows wastewater generated by the water purification unit to be collected in the wastewater tank, which is then pumped back into the domestic water inlet by the wastewater pump, achieving wastewater recycling.

[0004] However, installing a wastewater pump in the integrated water use equipment will make the overall volume of the integrated water use equipment larger. Summary of the Invention

[0049] In order to solve the technical problem in the prior art that the use of wastewater pumps will make the overall volume of the integrated water equipment relatively large, the present application provides an integrated water equipment that can reduce the overall volume and occupied space of the integrated water equipment.

[0050] See Figure 1-Figure 5 An embodiment of the present application provides an integrated water-using device 1, comprising a heating unit, a water purification unit, a wastewater treatment unit, and a domestic pipe, wherein the domestic pipe is provided with a domestic water inlet 26 and a domestic water outlet 24.

[0051] In which, the water purification unit is provided with a water inlet, a first wastewater outlet and a pure water outlet. The water inlet is connected to the domestic water inlet 26, and the first wastewater outlet is connected to the wastewater inlet of the wastewater tank. The tap water input by the domestic water inlet 26 is input into the water purification unit through the water inlet. The water purification unit filters and purifies the inflowing domestic water to obtain pure water and wastewater. The generated wastewater flows into the wastewater inlet of the wastewater tank through the first wastewater outlet, and is then collected in the wastewater tank 21. The purified water obtained after purification can be provided to users for drinking through the pure water outlet.

[0052] The heating unit is located between the domestic water inlet 26 and the domestic water outlet 24 and is connected to the domestic pipe. It is used to heat the domestic water flowing into the domestic water inlet 26 and then output it to the domestic water outlet 24.

[0053] The wastewater treatment unit includes a wastewater tank 21, a first one-way valve 27 and a first solenoid valve 6. The wastewater tank 21 is provided with a second wastewater outlet, a wastewater inlet, an exhaust port 20 and a first opening. The first solenoid valve 6 is respectively connected to the first opening of the wastewater tank 21 and the domestic water inlet. The first opening is used to collect tap water flowing in from the domestic water inlet.

[0054] The wastewater inlet is connected to the first wastewater outlet and is used to collect the wastewater filtered by the water purification unit;

[0055] The first one-way valve 27 is connected to the second wastewater outlet and the domestic pipe respectively. The second wastewater outlet is used to discharge the wastewater in the wastewater tank 21 into the domestic pipe and flow out together with the domestic water.

[0056] Since the water in the waste water tank 21 is much lower than the water discharged as domestic water, the mixed water has little impact on the quality of domestic water.

[0057] In this way, tap water can flow directly into the wastewater tank from the domestic water inlet, and the wastewater generated by the water purification unit can flow into the wastewater inlet of the wastewater tank through the first wastewater outlet, that is, the wastewater tank can collect tap water and wastewater generated by the water purification unit. When the water collected inside the wastewater tank is full, the exhaust port on the wastewater tank is blocked by water pressure. At this time, the wastewater tank can act as a water pipe, so that the wastewater in the wastewater tank can naturally flow into the domestic pipe and flow out together with the domestic water. That is, there is no need to set up a wastewater pump to achieve wastewater recovery and discharge, thereby reducing the overall volume and occupied space of the integrated water equipment.

[0058] In addition, since there is no need to set up a wastewater pump, the problems of high noise and high cost caused by using a pump to pump wastewater from a water tank can be solved.

[0059] In some embodiments, the wastewater treatment unit may further include a liquid level sensor 22 , which is disposed in the wastewater tank 21 and configured to detect the water level in the wastewater tank 21 .

[0060] In some embodiments, see Figure 2 and Figure 4 The wastewater in the wastewater tank 21 can flow directly to the domestic water outlet 24 through the second wastewater outlet.

[0061] Since the water quality of the wastewater in the wastewater tank 21 deteriorates slightly after being mixed with the raw water, in some embodiments, the first one-way valve 27 can be connected to the domestic water outlet 24. In this way, the mixed water in the wastewater tank 21 can flow out directly from the domestic water outlet 24, avoiding the mixed water entering the heating unit and then flowing out from the domestic water outlet 24, thereby avoiding the mixed water in the wastewater tank 21 affecting the service life of the heat exchanger 17 in the heating unit.

[0062] In other embodiments, see Figure 3 and Figure 5 The wastewater in the wastewater tank 21 can first flow to the heat exchanger 17 through the second wastewater outlet, and then flow to the domestic water outlet 24 through the heat exchanger 17.

[0063] In this way, the second wastewater outlet first flows to the heat exchanger 17 , and the heat exchanger 17 can be used to heat and sterilize the wastewater flowing out of the second wastewater outlet before flowing to the domestic water outlet 24 .

[0064] In some embodiments, see Figure 2 The water purification unit includes a water purification module 25, a water pump 23, a second solenoid valve 28, and a second one-way valve 5. The second solenoid valve 28 is connected to the domestic water inlet 26 and the first opening, respectively. The second one-way valve 5 is connected to the wastewater inlet of the wastewater tank 21 and the first wastewater outlet of the water purification module 25. The water pump 23 is connected to the water inlet of the water purification module 25 and the second solenoid valve 28. Thus, when the first solenoid valve 6 is opened, tap water input from the domestic water inlet 26 can partially flow into the wastewater tank 21 and partially flow into the water purification module 25.

[0065] When the wastewater tank 21 is full of wastewater, the first solenoid valve 6 can be closed to pump the water from the wastewater tank 21 into the water purification module 25 through the first opening, thereby avoiding the problem of wastewater not being able to enter after the wastewater tank 21 is full.

[0066] In other embodiments, the wastewater tank may be provided with a second opening, such as Figure 1 As shown, the water pump 23 and the second solenoid valve 28 can be provided at the second opening of the wastewater tank 21 to pump the water from the wastewater tank 21 into the water purification module 25, thereby avoiding the problem that the wastewater cannot enter after the wastewater tank 21 is full.

[0067] In addition, the water purification module 25 can adopt a pressure difference driven membrane separation filtration system, combined with different types of filter elements (such as RO filter elements, PCB filter elements, etc.), which can effectively remove various impurities and harmful substances in the water and provide high-quality purified water.

[0068] See Figure 1 When the wastewater tank 21 is full of wastewater, the first solenoid valve 6 can be closed to pump the water in the wastewater tank 21 into the water purification module 25, thereby avoiding the problem that the wastewater cannot be pumped into the wastewater tank 21 after it is full.

[0069] In some embodiments, the water purification module 25 can directly provide the purified water obtained after filtration to users.

[0070] In other embodiments, the purified water obtained after filtration by the water purification module 25 can be heated before being provided to the user. For details, please refer to 1. The water purification unit can also include an electric heater module 13, a flow control pump 11, a first temperature probe 12, and a second temperature probe 14. The water purification module 25 can connect the flow control pump 11 to input the purified water obtained into the electric heater module 13 for heating, so that the electric heater module 13 outputs heated drinking water to the drinking water outlet for the user. The first temperature probe 12 is used to detect the temperature of the purified water before being heated by the electric heater module 13, and the second temperature probe 14 is used to detect the temperature of the purified water after being heated by the electric heater module 13.

[0071] In some embodiments, the heating unit may include a fan 16, a heat exchanger 17, a burner assembly 10, a square tube proportional valve assembly 8, a circulation pump 9, and various connecting pipes. The connecting pipes may be in the form of bellows or copper pipes. The heating unit is used to provide domestic water.

[0072] See Figure 4 and Figure 5 In some embodiments, the integrated water use equipment is further provided with a third one-way valve 29 and a circulation pump 9. The living pipeline includes a cold water pipeline 30 and a hot water pipeline 31. The circulation pump 9 is located in the cold water pipeline 30. The third one-way valve 29 is connected to the cold water pipeline 30 and the hot water pipeline 31.

[0073] In this way, by setting a circulation pump 9 in the cold water pipe 30, when both domestic water and drinking water are closed, water can be circulated and pumped through the circulation pump 9, and the output water of the hot water pipe 31 can be output to the cold water pipe 30 for recycling again, so that the wastewater in the wastewater tank 21 is circulated and diluted in the domestic pipe. Since the water in the wastewater tank 21 is much lower than the tap water in the domestic pipe, the mixing of the water has little effect on the water quality of the inlet water, and the wastewater tank 21 is filled with the diluted inlet water again.

[0074] The above units provided in this application can be connected through corrugated pipes, copper pipes, hoses, PE pipes, etc., and play their respective functions.

[0075] The implementation principles of domestic water, drinking water and wastewater in the integrated water equipment provided in this application can be found below:

[0076] (1) Domestic water operation principle: Tap water flows from the domestic water inlet 26 into the heat exchanger 17. The heat exchanger 17 exchanges heat with the high-temperature flue gas generated by combustion in the burner assembly 10, and finally outputs the required domestic hot water from the domestic water outlet 24. During the combustion process, the fan 16 and the square tube proportional valve assembly 8 are reasonably matched to provide the required amount of gas and air for combustion.

[0077] (2) Operating principle of drinking water: Tap water first flows into the wastewater tank 21, and the water in the wastewater tank 21 is pumped into the purification module, and then filtered by the filter element in the purification module to obtain pure water and wastewater.

[0078] Among them, part of the pure water can flow out directly from the drinking water outlet 15, and the other part of the pure water can flow through the electric heating module 13 through the flow control pump 11 to be heated and then flow out from the drinking water outlet 15, and the waste water flows back to the wastewater tank 21 through the first wastewater outlet.

[0079] (3) Wastewater operation principle: Wastewater is collected through the wastewater tank 21. The liquid level sensor 22 in the wastewater tank 21 can monitor the water level, thereby controlling the opening and closing of the first solenoid valve 6. For example, when the wastewater tank is at a high liquid level, the first solenoid valve 6 is closed, the wastewater is filled with tap water, and the exhaust port is blocked by water pressure, so that the water in the wastewater tank 21 can be discharged through the second wastewater outlet along with domestic water, and can also be refluxed for recycling.

[0080] In addition, a one-way valve can be added to the second wastewater outlet of the wastewater tank 21 to prevent domestic water from flowing back into the wastewater tank 21. The specific wastewater utilization can be controlled according to the water use mode.

[0081] Based on the above-mentioned integrated water-using equipment, the present application further provides a wastewater discharge control method for the integrated water-using equipment, wherein the integrated water-using equipment is provided with multiple water-using modes, and the method comprises:

[0082] Step 110: Determine the current water usage pattern.

[0083] Step 120: Based on the current water usage mode, control the switch status of the first solenoid valve, the second solenoid valve, the first one-way valve and the domestic water outlet so that the wastewater tank collects tap water and / or wastewater generated by the water purification unit and then flows into the domestic pipeline.

[0084] Among them, step 120 may specifically include the following situations.

[0085] 1) If the current water use mode is a mode in which domestic water is on and drinking water is off, the second solenoid valve is closed, and the first solenoid valve, the first one-way valve, and the domestic water outlet are opened to allow tap water to be input into the wastewater tank through the first opening. When the exhaust port of the wastewater tank is blocked by water pressure, the wastewater in the wastewater tank is diverted to the domestic pipe through the second wastewater outlet.

[0086] 2) If the current water use mode is a mode where domestic water is off and drinking water is on, the first solenoid valve and the second solenoid valve are opened, the first one-way valve and the domestic water outlet are closed, and the water level of the wastewater tank is obtained in real time;

[0087] When the water level in the wastewater tank reaches a preset high level, the first solenoid valve is closed, and the wastewater in the wastewater tank is input into the water inlet of the water purification module through the first opening so as to be filtered and purified by the water purification module; when the water in the wastewater tank drops to a preset low level, the first solenoid valve is opened, and the cycle is repeated.

[0088] 3) If the current water use mode is the domestic water on / drinking water on mode, then the first solenoid valve, the second solenoid valve, and the domestic water outlet are opened, the first one-way valve is closed, and the water level of the wastewater tank is obtained in real time;

[0089] When the water level in the wastewater tank reaches a preset high liquid level, the first solenoid valve is closed, and the wastewater in the wastewater tank is input into the water inlet of the water purification module through the first opening, so as to be filtered and purified by the water purification module;

[0090] When the water in the waste water tank drops to a preset low liquid level, the first solenoid valve is opened to allow tap water to be input into the waste water tank through the first opening, and the cycle continues in this way.

[0091] 4) If the current water use mode is the domestic water off mode or the drinking water off mode, the first solenoid valve, the second solenoid valve, the first one-way valve and the domestic water outlet are closed.

[0092] In some embodiments, the living pipe includes a cold water pipe and a hot water pipe, the circulation pump is located in the cold water pipe, and the third one-way valve is connected to the cold water pipe and the hot water pipe.

[0093] Based on this, if the current water use mode is the domestic water off mode and the drinking water off mode, after closing the first solenoid valve, the second solenoid valve and the domestic water outlet, the circulation pump is used to guide the wastewater in the wastewater tank through the hot water pipe to the cold water pipe for recycling.

[0098] Based on the current water use mode, the switch states of the first solenoid valve, the second solenoid valve, the first one-way valve and the domestic water outlet are controlled so that the wastewater tank collects tap water and / or wastewater generated by the water purification unit and then flows into the domestic pipeline.
