Working principle of the present invention is: the user is according to the good water outlet 4 required water-exit temperatures of requirements set.
During work; Monitor the temperature of cooling water inlet 2 and hot water inlet 3 in real time by cold water temperature sensor 5 and hot water temperature's sensor 6; Water-exit temperature sensor 7 is the water-exit temperatures of monitoring water outlets 4 in real time, and when deviation appearred in water-exit temperature and setting temperature, controller obtained signal; And control cold water flow control mechanism or hot water flow control mechanism are regulated the flow proportional of cooling water inlet 2 or hot water inlet 3, so that water-exit temperature equals user's setting temperature.Temperature controlling is based on following formula:

Total-----total water flow is cold water flow and hot water flow sum
A-------cold water flow accounts for the ratio of total water flow
B-------cold water flow accounts for the ratio of total water flow
(i) can find out from formula, and the temperature of water outlet depends on cold/hot water water temperature and cold/hot water ratio in total water flow.Its controlling method has two kinds:
Method 1: cold water flow control mechanism and hot water flow control mechanism are worked simultaneously: when going out the water gaging temperature and be higher than user's setting temperature; The spool 10 of cold water flow control mechanism driving cold water side increases the flow of cold water, and the spool 10 of the hot water side of hot water flow control mechanism driving simultaneously reduces hot water flow.The cold water ratio rises and the decline of hot water ratio like this, thereby the water outlet water temperature is descended.When the measurement temperature was lower than user's setting temperature, the spool 10 of cold water flow control mechanism driving cold water side reduced the flow of cold water, and the spool 10 of the hot water side of hot water flow control mechanism driving simultaneously increases hot water flow.The cold water ratio descends and the rising of hot water ratio like this, thereby makes the water outlet water temperature rise.This controlling method is characterised in that controls adjustment simultaneously to the flow of cold/hot water, and the speed of control adjustment is fast and efficient is very high.This controlling method is applicable to heat-storaging water heating system (hot water storage that heats promptly being arranged in container).This water heating system is characterised in that the hot water water temperature can not change along with the unexpected variation of hot water flow.T like this
hIn control, keep constant, make the control reaction velocity fast and stable.
Method 2: it is main regulating water temperature with the work of cold water flow control mechanism, and the adjusting that the hot water flow control mechanism does not participate in exporting water temperature basically is to keep the stable of hot water flow.This controlling method is applicable to the system that hot water is provided with Instant heating type water heating device, like gas water-heater or electric heating immediately heating water heater.This device is characterised in that the temperature of hot water depends on the flow of hot water.Because the power of device is certain, hot water flow is big, and then the hot water water temperature is just low; Hot water flow is little, and then the hot water water temperature is just high.If employing method 1 is controlled, when regulating hot water flow, the hot water water temperature also can change.Will increase the difficulty of control like this, and it is unstable to be easy to occur the water outlet water temperature.And method 2 keeps the constant of hot water flow in control, and the hot water water temperature will keep constant like this, and the effect of control will be fine.
Temperature control realizes through flow control mechanism.The driving speed of flow control mechanism and driven amplitude are to be determined by controller.Controller is a cover programmed algorithm, and it is the drive signal that calculates the best through the difference of water-exit temperature of measuring and setting temperature.Controlling method 1 and 2 has a cover control algorithm separately.To measure the water water temperature more accurate in order to let, and the water-exit temperature measuring point begins mixing place and has some distances from cold and hot, can let hot and cold water fully mix like this, still, can cause the time-delay of measurement so again.Simultaneously, the temperature transducer time-delay that responds itself, flow control mechanism also has time-delay.If controller is too fast by the reaction velocity of flow control mechanism, because the existence of these time-delays, temperature control can occur unstable.If controller is slow excessively by the reaction velocity of flow control mechanism, the time that water-exit temperature reaches setting temperature needs very long.So controller needs balanced reaction speed and stability.
Temperature control comprises temperature main control and function of temperature compensation control.
The temperature main control is the difference that senses temperature and setting temperature according to water-exit temperature sensor 7, controls the ratio of cold water and hot water through a cover control algorithm, has reached temperature and has controlled.
Function of temperature compensation control is when the water inlet condition changes suddenly, to compensate control to make water-exit temperature not depart from setting temperature.Function of temperature compensation control is divided into compensation that entering water temp is changed and the compensation that water feeding pressure is changed.
In the temperature main control, when cold water or hot water water temperature changed, controller only sensed temperature variation at water-exit temperature sensor 7 and just can drive flow control mechanism temperature is revised.The outlet water temperature will depart from setting temperature earlier like this, and then gets back to setting temperature.The size that departs from depends on the into pace of change and the size of water water temperature.The compensation of entering water temp can reduce even eliminate this departing from.This compensation is to carry out sensing through the cold water temperature sensor 5 that is contained in cooling water inlet 2 and hot water inlet 3 places with 6 pairs of water inlets of hot water temperature's sensor water temperature; When the water inlet water temperature changes; The compensating controller of entering water temp sends drive signal makes flow control mechanism before water-exit temperature sensor 7 senses temperature variation, move cold water and the hot water ratio revised in advance; Thereby make the water outlet water temperature keep stable, do not depart from setting temperature.
The variation of water feeding pressure can be used the saliva temperature and departed from setting temperature.This is because the variation of water feeding pressure makes flow of inlet water change, thereby the ratio of cold water and hot water is changed.In the temperature main control, this variation has controller correction makes water-exit temperature return setting temperature.Be because controller only measures temperature variation in water-exit temperature sensor sense (7) just can be driven flow control mechanism temperature is revised equally, export water temperature like this and will depart from setting temperature earlier, and then get back to setting temperature.The size that departs from depends on the pace of change and the size of water feeding pressure.The water feeding pressure compensating for variations can reduce even eliminate the influence of variation in water pressure to the outlet water temperature.This compensation is one of most important characteristic of the present invention.This is a kind of mechanical type compensation, so can reach compensation in time fast.Its working principle can be explained through cold water flow control mechanism among Fig. 1.Fig. 3 is a seal ring 12 and spool 10 control sections sectional view partly in the flow control mechanism, and the size of flow depends on the pressure reduction and the circulation area size of water intake and water outlet 4.In invention, owing to itself can control flow, water outlet 4 does not generally need throttling arrangement, and outlet pressure is similar to atmospheric pressure, so the flow size is directly relevant with intake pressure.In circulation area one regularly, flow increases along with the increase of intake pressure, reduces along with the minimizing of intake pressure.When intake pressure one timing, flow increases along with the increase of circulation area, reduces along with the minimizing of circulation area.In the present invention, when seal ring 12 is in a certain position of spool 10 control sections, water feeding pressure has decisive role to circulation area.Circulation area when Fig. 3 a is depicted as certain intake pressure.Seal ring 12 receives the extruding of intake pressure and is out of shape, and circulation area is seal ring 12 after being out of shape and the area between the moving valve core 10.When intake pressure reduces suddenly, flow can reduce thereupon.But shown in Fig. 3 b, seal ring 12 receives intake pressure and diminishes, and makes extrusion-deformation diminish, and circulation area will increase like this, thereby the flow minimizing that the water feeding pressure minimizing is produced compensates.Such effect keeps changes in flow rate very little or constant exactly.When intake pressure increases suddenly, flow can increase thereupon.But shown in Fig. 3 c, seal ring 12 receives intake pressure and becomes big, makes extrusion-deformation become big, and circulation area will reduce like this, thereby the flow increase that the water feeding pressure increase is produced limits.Such effect keeps changes in flow rate very little or constant exactly.The characteristic of this seal ring 12 corresponding deformation with variation in water pressure makes; When seal ring 12 is in any one spool 10 control section position; When variation in water pressure; Spool 10 just need not move can keep stable by flow, and water-exit temperature also can keep stable like this, compensates thereby reach the temperature variation that the water feeding pressure variation is produced.
Flow control is to compare with the setting flow through the flow that the water flow sensor is recorded; Utilize the difference between them, produce the moving valve core 10 that the controlling and driving signal drives cold water and hot water side by flow dontroller and make water flow reach the setting flow.The control algorithm that flow dontroller uses can be in control flow rate, and the water outlet water temperature can not be affected.
Rre-heated:
General water admixing device will just can reach setting temperature through water-exit temperature after a while after unlatching.This be because when water admixing device a period of time need not after, the hot water among the hot water inlet pipe cools off, after opening, after the water of these coolings will be discharged earlier, the water outlet that hot water could flow into also and cold water mix goes out setting temperature.Water admixing device among the present invention has the ideational function of preheating.When rre-heated started, water admixing device was opened, because the water temperature of water is lower than setting temperature in the hot-water line, the cold water flow control mechanism is closed cold water, and the hot water flow control mechanism opens to peak rate of flow with hot water discharges the cold water in the hot-water line as early as possible.After the cold water in the hot-water line was discharged, high-temperature-hot-water flowed into water admixing device.Cold water and hot water mix, and when the water outlet water temperature reached setting temperature, water admixing device was closed water outlet 4, get into to wait for shape.Sound simultaneously or light signal points out the preheating of user's water admixing device to finish, at this moment, when the user opens the water outlet that water admixing device can obtain setting temperature at once.Wait state is free restriction, does not still open after wait state surpasses a period of time when being in, and water admixing device can be got back to halted state.
Overheat protector:
Water admixing device among the present invention has dual excess temperature safety protection function.As shown in Figure 4, water-exit temperature sensor 7 can use the two-port temperature transducer.One of them port 71 is used for temperature control, and this port 71 also is used for overheat protector simultaneously.71 of another ports are to be specifically designed to overheat protector.When any one port 71 measurement temperature was higher than the warning value of setting, closed electromagnetic valve cut off water outlet to prevent scald.Simultaneously, be provided with maximum setting temperature, make that water-exit temperature is too high and cause scald to prevent user misoperation.
Intelligent wash and high-temperature sterilization function:
After water admixing device did not use in a period of time, be easy to breed bacterium in the water that amasss inside and export.The intelligent wash function can be with its unlatching after water admixing device does not use a period of time.So just can discharge the ponding of the inside, thus the cleaning of maintenance water admixing device.The blanking time of intelligent wash and washing time can be set by the user according to specific circumstances.
High-temperature sterilization function water admixing device can be closed the cold water water inlet, only lets high-temperature-hot-water flow to, and so just can utilize the high temperature of this water to carry out high-temperature sterilization to mixing the water sole duty.Because sterilization only needs high temperature, so when high-temperature sterilization, with minimum flow.Can reach the purpose of energy-saving and water-saving like this.
Network function:
It is interconnected that network function is meant that a water admixing device and another one or a plurality of water admixing device can carry out, and is linked on computer or the server again.Can be connected on the internet through server, can be implemented on any one computer that is connected to the internet a plurality of water admixing device high-efficiency management.The caretaker can monitor the runnability of each water admixing device, revises to be provided with, and fault diagnosis and reparation, and write down its service data.This function is highly beneficial for the place that many water admixing devices have been installed, such as hotel, hospital and bath center or the like, because this function can be saved a lot of manpowers and time.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
