Detailed description of the invention
Be described below in detail embodiments of the present invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
As shown in Figure 1 and Figure 2, solar water heater Intelligent water control device is by running water pipe 1, water supply valve door 2, Your Majesty's downcomer 3, water tank 4, micro pump 5, pipe temperature sensor 6, auxiliary pipe 7, form by tap 8, cooling-water temperature sensor 9, control module 10.Open water supply valve door, the running water of being come by running water pipe enters water-heater water tank through Your Majesty's downcomer, closes water supply valve door after filling water.As long as open control module power supply, it just carries out work according to program setting, according to the temperature information that pipe temperature sensor and cooling-water temperature sensor are sent here, controls unlatching and the stopping of micro pump, thus realizes the automatic control of Guan Wenyu water temperature.
Your Majesty's downcomer is exactly Your Majesty's downcomer that general water heater all must have, and function had both been poured water (upper water) to water-heater water tank by this pipe, at closedown water supply valve behind the door, can use during hot water and carry out discharge water (lower water) again.Auxiliary pipe upper end is inserted in water-heater water tank, but on the water level of the mouth of pipe in water-heater water tank, water in water-heater water tank can not flow to tap by auxiliary pipe, and the major function of auxiliary pipe forms the circulation canal between water-heater water tank-Your Majesty's downcomer-auxiliary pipe-water-heater water tank.
When opening under being arranged on the control of the micro pump on auxiliary pipe in control module, the current route of this water circulation system is: water-heater water tank-Your Majesty's downcomer-auxiliary pipe-micro pump-auxiliary pipe upper end-water-heater water tank.This closed loop, the loss of a water is not had in this circulation, certainly the heat losses also just do not taken away due to the loss of water, and this circulation just, original in pipeline the cold water got off again send water tank back to, the hot water intake line in water tank, the heating temperatures pipeline of water, through the circulation of very short time, usual 1 to 2 minutes, open when using tap, the temperature of water outlet just can reach require that of use (having a bath, wash one's face, wash dish, wash the dishes).Because the water surface in water tank and tank top water inlet water-head only have an appointment 20 centimetres, therefore the consumed power of micro pump is minimum, only need several watts, and the working time is very short, very energy-conservation, consumes energy almost negligible.This circulatory system key has single-chip microcomputer as controller, automatically completes this function according to program setting, thus also just seems very comfortable, convenient, handy.
As shown in Figure 3, the opening and stop controlled module and control of micro pump, control module, according to the setting of program, adopts two kinds of control modes to control opening and stopping of micro pumps.A kind of mode is automatic control, its working method is: the startup of the pipe temperature information that control module sends according to pipe temperature sensor and program setting and stop temperature value comparing, be less than or equal to initiation value (supposing that initiation value is 5.0 degree), open micro pump, be more than or equal to stop value (supposing that initiation value is 10.0 degree), stop micro pump; Namely be less than 5 degree automatically to open, be greater than 10 degree and automatically close, this function can only just can automatically perform in the winter time, because this function protects water pipe not by bursting by freezing exactly, spring and summer temperature cool autumn weather is all greater than 10 degree.
Another kind of mode is that people is controlled, and why arranges as people's control, is because people's control can reduce heat energy loss to greatest extent.If because automatic control, leaving water temperature to remain more than 40 degree, no matter you use hot water to that control module, and it all can open micro pump automatically, makes water temperature remain on more than 40 degree.So, one opens with tap, and hot water is just out, very comfortable; But when you do not use hot water, the water temperature in water pipe is all more than or equal to 40 degree all the time, and so, because conduit temperature is high, the heat externally distributed is just many, and the temperature difference is larger, heat energy loss is larger, and in non-linear increase, thus adds thermal losses; This in the winter time, environment temperature is lower, and when 40 degree of leaving water temperature differences of environment temperature and setting are larger, and this loss is just particularly evident.In order to maximally utilise heat energy, controller have employed this design of Artificial Control leaving water temperature.When you need to use hot water, only need flicking hot water button once, to control module signal, after control module receives signal, water temperature controls indicator lamp and is namely lit, control module runs water temperature control program immediately, check the temperature information that cooling-water temperature sensor sends, be less than setting value (40 degree) and just start micro pump immediately, within usual 1 to 2 minutes, water temperature just can reach instructions for use, so, only need wait 1 to 2 minutes, just have the hot water being applicable to requiring available, this is very convenient and comfortable.
After you are finished hot water, be saving heat energy, you can press a hot water button again, and water temperature controls indicator lamp and namely extinguished, and control module exits water temperature control program immediately, closes micro pump.Certainly, you have forgotten by hot water button or have not want that control module controls leaving water temperature by also having no relations always after being finished hot water, when you open tap more out be exactly hot water, without the need to waiting for, just because pipe temperature is all the time more than 40 degree, some thermal losses.Control module inherently long-term work can control water temperature and is not controlling water temperature two kinds of duties.Arranging hot water button is conveniently user purely, reduces pipeline thermal losses to greatest extent and designs.
Above embodiment is only and technological thought of the present invention is described, can not limit protection scope of the present invention with this, and every technological thought proposed according to the present invention, any change that technical scheme basis is done, all falls within scope.
