Detailed Description
The invention is described in further detail below with reference to the following examples of the drawings.
As shown in figures 1-4, an automatic water temperature regulating system comprises a water inlet pipe 2 and a water outlet pipe 3. The water inlet pipe 2 is provided with a water quantity sensor 6 with a first temperature sensor, the water outlet pipe 3 is provided with a water quantity servo device 4 with a second temperature sensor, and a quick water mixing device 1 is arranged between the water inlet pipe 2 and the water outlet pipe 3.
The above-mentioned quick water mixing device 1 includes first water pipe 11, second water pipe 12 and mixes water pipe 15, and in this embodiment, first water pipe 11 is the hot water pipe, and second water pipe 12 is the cold water pipe. A connection valve 14 is further included, and the connection valve 14 includes a first port 141 connected to the first water pipe 11, a second port 142 connected to the second water pipe 12, and a third port 143 connected to the mixing water pipe 15. In this embodiment, the first port 141 and the second port 142 are oppositely disposed, specifically, the left side and the right side of the connection valve 14 are oppositely disposed with a first water pipe 11 and a second water pipe 12, wherein the first water pipe 11 is vertically disposed and connected to the first port 141 through the adapter pipe 16, the second water pipe 12 is horizontally disposed, and the mixing water pipe 15 is located below the connection valve 14 and vertically disposed.
The inner cavity of the connecting valve 14 forms a mixing chamber 140, in which mixing chamber 140 a mixing wick 5 is arranged. One end of the mixing tube core 5 is open, and the outer peripheral surface of the open end 51 is provided with an external thread 55, and is in threaded connection with the inner peripheral wall of the first port 141 through the external thread 55, so that the open end 51 is communicated with the nozzle of the first water pipe 11; the other end of the mixing tube core 5 is closed, a water outlet hole 53 is arranged on the side wall of the mixing tube core 5, the mixing tube core 5 is transversely arranged above the tube opening of the mixing water pipe 15, the water outlet hole 53 is staggered with the tube opening of the mixing water pipe 15, an annular flow channel 17 is formed between the outer peripheral wall of the mixing tube core 5 and the wall of the mixing cavity 140, and the annular flow channel 17 is communicated with the tube opening of the second water pipe 12.
The water outlet 53 is close to the closed end 52, and the four water outlets 53 are arranged along the circumferential direction of the mixing tube core 5, so that the mixing tube core 5 can uniformly discharge water and the water can be fully mixed with the water discharged from the second water pipe 12. The first water mixing area 18 is formed by leaving a gap between the end surface of the closed end 52 and the nozzle of the second water pipe 12, the outer side surface of the closed end 52 is formed with a radially extending annular flange 54, and a water gap 171 is formed between the annular flange 54 and the wall of the mixing chamber 140. The water flowing gap 171 can further increase the flow rate of the water from the water outlet 53 to the first water mixing area 18, so that the cold water and the hot water can be mixed more sufficiently and rapidly in the first water mixing area 18. Further, an annular shoulder 56 extending in the radial direction is formed on the outer peripheral surface of the mixing tube core 5 on the side of the outlet hole 53, and the annular shoulder 56 faces the water passage gap 171.

The water temperature self-regulating system is suitable for various devices needing to regulate water temperature, in particular for water heaters (such as gas water heaters with large liter number), and the control principle of the water temperature self-regulating system is explained by taking the application of the water temperature self-regulating system in the water heater as an example:
T out (A+B)＝T in A+ThB，A(T out -T in )＝B(T h -T out ) Wherein: t is out The temperature (DEG C) of hot water at the outlet of the water heater is the temperature of the hot water which is dischargedWater temperature at the outlet of the water pipe 3; t is a unit of in The water temperature (DEG C) at the inlet of the water heater, namely the water temperature at the inlet of the water inlet pipe 2; t is a unit of h The temperature (DEG C) of the high-temperature water after passing through the heat exchanger; a is water flow (L/min) flowing through the water flow self-regulating system; and B is water flow (L/min) passing through the heat exchanger.
The use is started: the water heater starts to work after a user sets the outlet water temperature and opens the water inlet valve, the water quantity sensor 6 judges whether the water flow flowing through the system is larger than the starting water flow of the water heater, when the water flow is larger than the starting water flow, the water quantity servo device 4 starts to work, and the second temperature sensor feeds back the outlet water temperature T out . When the outlet water temperature does not reach the set temperature value of the water heater, the water quantity servo device 4 feeds back the low-temperature water temperature T according to the first temperature sensor in According to a control principle equation of the water temperature self-regulating system, starting to regulate the low-temperature water flow A entering the water temperature self-regulating system; meanwhile, the high-temperature water and the low-temperature water are mixed in the rapid water mixing device 1, and if the temperature of the mixed water fed back by the second temperature sensor reaches a set value, the water temperature self-regulating system finishes working. If the temperature does not reach the set value, the water temperature self-regulating system starts further temperature regulation, and the water temperature can quickly reach the set temperature through the work of the water temperature self-regulating system.
Closing water for a period of time and then using: when the water heater without the water amount self-adjusting system is used, after water is turned off for a period of time, the temperature of high-temperature water flowing out of the heat exchanger can be suddenly increased due to the fact that the high-temperature fins in the heat exchanger dissipate heat to the periphery, after a user opens the water valve again, a section of high-temperature hot water can appear to enable the user to be incapable of continuing bathing, and then a section of cold water can appear to influence the bathing effect. In view of the situation, the water temperature self-regulating system in this embodiment can rapidly supply a section of cold water to be mixed with high-temperature water in the rapid water mixing device 1, the temperature of the outlet water is rapidly reached, when the temperature of the outlet water of the heat exchanger reaches normal temperature, the system automatically regulates the amount of low-temperature water, and the situation that the temperature of the outlet water is too high to bath after the water heater is restarted, and then a section of cold water suddenly appears is avoided.
In this embodiment, the open end of the mixing tube core of the rapid water mixing device is communicated with the hot water pipe, and certainly, the open end can also be communicated with the cold water pipe, so that cold water flowing out of the water outlet hole on the mixing tube core is mixed with high-temperature water, and the water temperature can also be adjusted, that is, the structure that the open end of the mixing tube core is communicated with any one of the hot water pipe and the cold water pipe belongs to the protection scope of the present invention.
