In addition, existing instant hot water dispensers have low water output when dispensing hot water at high temperatures; the water temperature does not reach 100℃, resulting in a poor user experience; and in the hot and cold water mixing mode of the purifier-heater combo, there is a risk of scalding when users fill their cups with warm or hot water because cold and hot water mix. Furthermore, the water output varies depending on the temperature.

Figure 2 As shown, the inlet valve and adjustable module are replaced with a cold water outlet valve and a PVL-24-FT2 negative pressure regulating valve, respectively. The above-mentioned utility model uses dual filtration of a composite filter element and an RO reverse osmosis membrane. The integrated valve design reduces the number of components, simplifies the system structure, and facilitates installation and maintenance. Figure 1 The system shown has the disadvantages of low water output and water temperature not reaching 100℃ when producing high-temperature hot water.

Detailed Implementation

[0021] Example 1: See Figures 4 to 10 ,like Figure 4 As shown, the present invention relates to a constant flow temperature-regulating mixing system for a combined air purifier and heat exchanger, comprising an integrated valve 1 and a heat tank 2. The integrated valve 1 is equipped with an adjustable flow module I3, an adjustable flow module II4, and a mixing chamber 5. The flow rates H1 of the adjustable flow module I3 and H2 of the adjustable flow module II4 are adjustable. The outlet of the adjustable flow module II4 is connected to the inlet of the heat tank 2, and the outlet of the heat tank 2 is connected to the mixing chamber 5. The outlet of the adjustable flow module I3 is also connected to the mixing chamber 5.

[0022] like Figures 5 to 8As shown, the integrated valve 1 also includes an inlet pressure reducing and stabilizing valve 6, which is connected to adjustable flow module I3 and adjustable flow module II4 respectively. The composite filter element 7, RO reverse osmosis membrane 8, and inlet pressure reducing and stabilizing valve 6 are connected in series. The bottom of the hot tank 2 is the inlet, and the top is the outlet. It also includes an inlet 9, an outlet 10, a hot tank outlet 10, a solenoid valve assembly 12, a valve body 13, a first thermistor 14, a second thermistor 15, a pressure reducing valve assembly 16, a stepper motor 17, a rotating shaft 18, and a flow regulating valve. The system includes a flow regulating plate 19 and a flow control plate 20; the inlet 9 is connected to a water source; the mixing chamber 5 is connected to the outlet 10 and the hot tank 2 respectively; the hot tank 2 is connected to the outlet 10 of the hot tank; the valve body 13 is connected to the outlet 10 and the stepper motor 17; the first thermistor 14 is installed on the inlet 9; the second thermistor 15 is installed on the outlet 10; the pressure reducing valve assembly 16 is connected to the solenoid valve assembly 12; the flow regulating plate 19 is connected to the flow control plate 20; and the rotating shaft 18 is connected to the flow regulating plate 19. 9 and flow control plate 20; the flow control plate 20 is provided with a hot water outlet 21 and a cold water outlet 22, and the flow regulating plate 19 is provided with an arc-shaped flow regulating port 23. The flow regulating port 23 is installed in conjunction with the hot water outlet 21 and the cold water outlet 22. After the flow control plate 20 and the flow regulating plate 19 are inserted into the cold water outlet 22 and the hot water outlet 21, the sum of the water flow rates of the cold water outlet 22 and the hot water outlet 21 is constant in all states; the flow control plate 20 and the flow regulating plate 19 is relatively rotatable; a valve body 13 is provided inside the mixing chamber 5, and the rotating shaft 18 passes through the valve body 13 and is connected to the flow regulating plate 19 and the flow control plate 20; the stepper motor 17 is provided at one end of the valve body 13 and is connected to the rotating shaft 18 inside the valve body 13 through a mechanical transmission device; the hot tank 2 is connected to the mixing chamber 5 through a pipe, and the hot tank outlet 11 is provided inside the hot tank 2; the flow rate H1 of the adjustable flow module I3 and the flow rate H2 of the adjustable flow module II4 are constant when added together at all outlet water temperatures.

[0023] See Figure 9 and Figure 10In this embodiment, the flow regulating plate 19 is fixed on the valve body 13 and cannot rotate around the rotating shaft 18. The flow control plate 20 is connected to the valve body 13 through the rotating shaft 18 and can rotate around the rotating shaft 18. In state 1, where the water is mixed with cold water at one of the following temperatures, cold water enters the system from the inlet 9, and hot water flows from the hot tank 2 through the hot tank outlet 10 into the mixing chamber 5. In the mixing chamber 5, the cold water and hot water are mixed by the flow regulating plate 19 and the flow control plate 20. The hot water outlet 21 and cold water outlet 22 of the flow regulating plate 19 and the arc-shaped flow regulating port 23 on the flow control plate 20 partially overlap, forming a mixing channel for cold and hot water. The stepper motor 17 drives the flow regulating plate 19 and the flow control plate 20 through the rotating shaft 18, so that the gap between the two can be adjusted as needed, thereby controlling the mixing ratio of hot and cold water. By adjusting the relative position of the flow regulating plate 19 and the flow control plate 20, and based on the feedback from the first thermistor 14 and the second thermistor 15, the relative position of the two is adjusted to control the mixing ratio of hot and cold water, ensuring a constant outlet water temperature. It can achieve mixed water output at different temperatures. This embodiment can adjust the mixing ratio of hot and cold water according to user needs to meet different temperature requirements, making it suitable for household scenarios.

[0024] Example 2: See Figure 11 This embodiment is basically the same as embodiment 1, except that: the flow control plate 20 is fixed on the valve body 13 and cannot rotate around the shaft 18, while the flow regulating plate 19 is connected to the valve body 13 through the shaft 18 and can rotate around the shaft 18; in the state 2 where cold water is discharged, the hot water outlet 21 and cold water outlet 22 of the flow regulating plate 19 and the arc-shaped flow regulating port 23 on the flow control plate 20 completely overlap, forming a single channel for cold water; the stepper motor 17 drives the flow regulating plate 19 and the flow control plate 20 to completely overlap, ensuring that only cold water flows through the mixing chamber 5 to the outlet 10. Through this design, it can be ensured that cold water flows out directly without mixing with hot water. This embodiment is suitable for industrial processes that require rapid cooling, such as cooling system or equipment cleaning.

[0025] Example 3: See Figure 12This embodiment is basically the same as embodiment 1, except that: both the flow regulating plate 19 and the flow control plate 20 are connected to the valve body 13 through their respective rotating shafts 18; the rotation of the flow regulating plate 19 changes the position of the flow regulating port 23, and the rotation of the flow control plate 20 changes the position of the hot water outlet 21 and the cold water outlet 22; in the state of hot water outlet 3, the hot water outlet 21 and the cold water outlet 22 of the flow regulating plate 19 and the arc-shaped flow regulating port 23 on the flow control plate 20 are completely separated, forming a single channel for hot water. The stepper motor 17 drives the flow regulating plate 19 and the flow control plate 20 to completely separate, ensuring that only hot water flows through the mixing chamber 5 to the outlet 10. Through this design, it can be ensured that hot water flows out directly without mixing with cold water. This embodiment is suitable for providing a stable supply of hot water in industrial processes that require hot water cleaning, such as food processing or equipment cleaning.

[0026] Working principle: First, cold water enters the system through inlet 9, undergoes preliminary filtration through composite filter element 7, and then enters the RO reverse osmosis membrane 8 and inlet pressure reducing and stabilizing valve 6. Cold and hot water mix in mixing chamber 5, which contains valve body 13. A rotating shaft 18 passes through valve body 13 and is connected to flow regulating plate 19 and flow control plate 20. When hot and cold water mixing is required, stepper motor 17 drives rotating shaft 18 to adjust the positions of hot water outlet 21 and cold water outlet 22 on flow regulating plate 19 and the arc-shaped flow regulating port 23 on flow control plate 20, thus controlling the mixing ratio of hot and cold water. When cold water is needed, stepper motor 17 drives the hot water outlet 21 and cold water outlet 22 on flow regulating plate 19 and the arc-shaped flow regulating port 23 on flow control plate 20. The flow regulating ports 23 completely overlap, forming a single channel for cold water. Cold water flows directly from the inlet 1 to the outlet 10 without mixing with hot water. When hot water is needed, the stepper motor 17 drives the hot water outlet 21 and cold water outlet 22 of the flow regulating plate 19 and the arc-shaped flow regulating port 23 on the flow control plate 20 to completely separate, forming a single channel for hot water. Hot water flows directly from the hot water tank outlet 4 to the outlet 10 without mixing with cold water. Based on the feedback from the first thermistor 14 and the second thermistor 15, the stepper motor 17 adjusts the position of the flow regulating plate 19 and the flow control plate 20 to ensure a constant outlet water temperature. The pressure reducing valve assembly 10 is connected to the solenoid valve assembly 6 to regulate the inlet water pressure and ensure stable operation of the system under different water pressures.
