Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] Reference Figure 1 A water purifier, comprising:

[0029] The water purification pipeline is equipped with a booster pump 110 and a reverse osmosis filter element 120 in sequence along the water flow direction;

[0030] The ambient temperature water pipeline is connected to the outlet of the purified water pipeline. The ambient temperature water pipeline is equipped with a first solenoid valve 210. In the ambient temperature water mode, the booster pump 110 works, the first solenoid valve 210 is opened, and the other solenoid valves are closed. The filtered pure water passes through the first solenoid valve 210 to the faucet 900.

[0031] The first hot water pipeline is connected to the outlet of the purified water pipeline. Along the water flow direction, the first hot water pipeline is sequentially equipped with a second solenoid valve 310, a preheating tank 320, a water pump 330, and an instant heating module 340. The instant heating module 340 is a thick-film heating module. In hot water mode, all solenoid valves are closed, the machine does not produce water, and the water pump 330 draws preheated hot water from the preheating tank 320, which is then reheated by the thick-film heating module. This greatly improves heating efficiency, allowing the machine to produce a large amount of hot water instantly. When the preheating tank 320 is short of water, the water replenishment mode is activated. At this time, the booster pump 110 works, the second solenoid valve 310 opens, and the other solenoid valves close. Pure water enters the preheating tank 320 through the second solenoid valve 310 until the high water level switch of the preheating tank 320 is activated, at which point the water replenishment stops. In the high-flow-rate warm water mode, the booster pump 110 and the water pump 330 work, the first solenoid valve 210 opens, and the other solenoid valves close. At this time, the machine's water output reaches the maximum flow rate, and the preheated hot water + room temperature water form a high-flow-rate warm water.

[0032] The cold water pipeline is connected to the outlet of the purified water pipeline. A third solenoid valve 410 and an ice tank 420 are sequentially installed along the water flow direction on the cold water pipeline. In cold water mode, the booster pump 110 operates, the third solenoid valve 410 opens, and the other solenoid valves close. Filtered pure water enters the bottom of the ice tank 420, forcing out the cold water stored in the ice tank 420, and cold water flows out from the faucet 900.

[0033] In some embodiments of this utility model, a return pipeline is also included. The inlet end of the return pipeline is connected to the outlet end of the purified water pipeline, and the outlet end of the return pipeline is connected to the inlet end of the purified water pipeline. A fourth solenoid valve 510 and a first one-way valve 520 are sequentially arranged along the water flow direction on the return pipeline. In zero-stagnant water mode, the booster pump 110 operates, the fourth solenoid valve 510 opens, and the other solenoid valves close. Pure water flows back to the booster pump 110 through the return pipeline, and the booster pump 110 flushes away the wastewater remaining in the purified water pipeline, so that both the upstream and downstream of the reverse osmosis filter element 120 are in a low TDS state, and the reverse osmosis filter element 120 does not undergo forward osmosis, thereby achieving the purpose of zero-stagnant water.

[0034] In some embodiments of this invention, a first temperature sensor 350 and a second temperature sensor 360 are provided on the first hot water pipe. The first temperature sensor 350 is located between the water pump 330 and the instant heating module 340, and the second temperature sensor 360 is located downstream of the instant heating module 340. The first temperature sensor 350 monitors the preheated water temperature in real time and feeds the temperature signal back to the control system, thereby dynamically adjusting the heating power of the instant heating module 340 and optimizing heating efficiency. The second temperature sensor 360 detects the outlet water temperature after heating by the instant heating module 340, ensuring that the final hot water temperature flowing out of the faucet 900 meets the set value. If the outlet water temperature deviates from the set value, the system will adjust the power of the instant heating module 340 through a feedback mechanism, forming a closed-loop control to ensure a constant water temperature during user use and improve the user experience.

[0035] In some embodiments of this utility model, a flow meter 370 is provided on the first hot water pipe, and the flow meter 370 is located between the water pump 330 and the first temperature sensor 350. The flow meter 370 can provide real-time feedback on whether the current flow rate has reached a preset value.

[0036] In some embodiments of this utility model, a second hot water pipeline is also included. The inlet end of the second hot water pipeline is connected to the outlet end of the purified water pipeline. The outlet end of the second hot water pipeline is connected between the water pump 330 and the flow meter 370. A fifth solenoid valve 610 and a flow control valve 620 are sequentially arranged along the water flow direction on the second hot water pipeline. When the water in the preheating tank is insufficient, hot water can be supplied through the second hot water pipeline. Or, when the required outlet water temperature is lower than the preset water temperature of the preheating tank 320, warm water can also be supplied through the second hot water pipeline. Specifically, the booster pump 110 is working, the water pump 330 is not working, the fourth solenoid valve 510 and the fifth solenoid valve 610 are open, and the other solenoid valves are closed. The filtered pure water flows through the fifth solenoid valve 610 to the flow control valve 620. Excess water will flow back to the booster pump 110 through the return pipeline, thereby ensuring the stable operation of the system. The limited pure water is heated by the instant heating module 340 and then flows out from the faucet 900. In this mode, the hot water needs to be heated from room temperature, so the flow rate will be significantly lower than that of the preheated water.

[0037] In some embodiments of this invention, a third temperature sensor 630 is provided on the second hot water pipe, and the third temperature sensor 630 is located downstream of the flow control valve 620. In order to ensure the heating efficiency of the instant heating module 340, the flow control valve 620, in conjunction with the third temperature sensor 630, limits the flow rate of the room temperature water.

[0038] In some embodiments of this utility model, a water inlet pipe is also included. The inlet end of the water inlet pipe is connected to a tap water pipe, and the outlet end of the water inlet pipe is connected to the inlet end of the purified water pipe. A pre-filter 710 and a sixth solenoid valve 720 are sequentially arranged along the water flow direction on the water inlet pipe. The pre-filter 710 is typically made of materials such as PP cotton and activated carbon, and can filter large particulate impurities (such as sediment and rust), residual chlorine, and organic matter from tap water. The sixth solenoid valve 720 serves as the main water inlet switch for the water purifier and is automatically controlled by the control system according to the working mode.

[0039] In some embodiments of this utility model, a post-filter 130 is also provided on the water purification pipeline, and the post-filter 130 is located downstream of the reverse osmosis filter 120. The post-filter 130 is usually made of granular activated carbon or compressed activated carbon, which can adsorb trace amounts of odor substances remaining in the water after reverse osmosis filtration, as well as the small amount of polymer material odor that may be released by the reverse osmosis membrane, making the water taste sweeter and smoother.

[0040] In some embodiments of this utility model, a wastewater pipeline is also included, which is connected to the wastewater outlet of the reverse osmosis filter element 120. The wastewater pipeline is equipped with a wastewater solenoid valve 810 and a second one-way valve 820. After entering the reverse osmosis filter element 120, the water is divided into two streams: one part passes through the reverse osmosis membrane, and the other part flows over the surface of the reverse osmosis membrane and then through the wastewater outlet to the wastewater pipeline. The second one-way valve 820 prevents wastewater from flowing back into the reverse osmosis filter element 120.

[0041] In some embodiments of this utility model, a third one-way valve 430 is provided on the cold water pipeline, and the third one-way valve 430 is located downstream of the ice tank 420. The third one-way valve 430 only allows cold water to flow from the ice tank 420 to the faucet 900, preventing water from the faucet 900 from flowing back into the ice tank 420, thus avoiding contamination of the cold water stored in the ice tank 420.

[0042] In some embodiments of this utility model, a faucet 900 is also included, and the outlet end of the normal temperature water pipe, the outlet end of the first hot water pipe, and the outlet end of the cold water pipe are all connected to the faucet 900.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
