Said temperature sensor 363 is arranged at the upper end outer cylinder of vertical cylinder 351.The said temperature sensor is attached to hot conduction band 362 1 side surfaces that twine vertical cylinder 351 outer cylinders, generates temperature with vertical cylinder 351 to corresponding electronic signal.Said temperature sensor 363 discharges different voltage according to different temperatures.
In addition, steam generator 350 of the present invention is arranged at a certain distance from the position of sitting smoked device and Pediluvium apparatus, be connected with the steam supply pipe 340 that limits length, because of adopting the much bigger vertical cylinder 351 of length diameter group, its highest water surface has certain distance from steam discharge hole 364.
As shown in the figure, on the water injection pipe 342 between above-mentioned catch basin 310 and the water filling device 353, supply-water pump 370 is set.This supply-water pump 370 can be fed to the water in the catch basin 310 in the vertical cylinder 351.With this kind method, utilize supply-water pump 370 to force water fillings, just the water level with catch basin has nothing to do, and can supply institute's water requirement at any time, and water level that can free adjustment vertical cylinder 351 inside.
The power supply unit supply power supply that above-mentioned supply-water pump 370 is not done to indicate by drawing is by controlling organization 390 gauge taps.When the temperature that above-mentioned controlling organization 390 measures at temperature sensor 363 reaches the maximum temperature of setting, start and water supply start, supplied water by the startup of above-mentioned supply-water pump 370, the water level in the vertical cylinder 351 begins to rise.The time that measures along with the timer 391 of above-mentioned controlling organization 390 is when surpassing setting-up time, interruption of work and stop to supply water.Above-mentioned supply-water pump 370 stops to supply water, and then the water level in the vertical cylinder 351 will progressively descend.
In sum, method for controlling water level of the present invention, it is characterized in that not according to water level control sensor, reach the purpose of regulating water level but utilize temperature sensor and timer to control supply-water pump, ultralow water level is discerned according to temperature sensor 363, and the superelevation water level is identified as its feature according to timer 391.That is, whether the water levels in the vertical cylinder 351 reach lowest water level is discerned according to temperature sensor 363, and whether the water levels in the vertical cylinder 351 reach peak level is discerned according to timer 391 and control water level.
Why not only adopt temperature sensor 363, also adopt the reason of timer 391 to be simultaneously, even because the water level in the vertical cylinder 351 rises because of the injection of outside water, the temperature of vertical cylinder 351 can't reduce rapidly because of the rising of water level is corresponding.That is, when the water levels in the vertical cylinder 351 reached peak level, the temperature of vertical cylinder 351 can not reach minimum temperature, so utilize temperature sensor 363 can't correctly discern peak level in the vertical cylinder 351.
Shown in the coordinate diagram of Fig. 6, the variations in temperature coordinate diagram (first) of vertical cylinder 351, change repeatedly between high temperature and low temperature as time goes by.The fluctuation of water table coordinate diagram (second) of vertical cylinder 351, change repeatedly between high water level and low water level as time goes by.Contrast two coordinate diagram, when the temperature that can learn vertical cylinder 351 reaches maximum temperature (t2), the water level of vertical cylinder 351 has also reached lowest water level.That is, vertical cylinder 351 time point that reaches maximum temperature is consistent with the time point (t2) that water levels in the vertical cylinder 351 reach lowest water level.
On the contrary, to reach the time point (t3) that water levels in the time point (t4) of minimum temperature and the vertical cylinder 351 reach peak level be inconsistent to the temperature of vertical cylinder 351.Its reason be exactly the temperature of vertical cylinder 351 be not that water level along with vertical cylinder 351 raises and proportional reduction.So, the temperature of vertical cylinder 351 reaches the time point (t4) of minimum temperature if supply-water pump 370 is worked always, then the time goes up and surpasses the time point (t3) that vertical cylinder 351 reaches peak level, causes the water glut, may cause the situation of the outside splash of hot water to take place.
In order to solve such problem, the present invention adopts temperature sensor 363 and timer 391 to come the work of supply-water pump 370 is controlled simultaneously.That is, under the situation of the discharge capacity of known supply-water pump 370 and vertical cylinder 351 volumes, calculate the working time of supply-water pump 370, can regulate the water level in the vertical cylinder 351 accurately.
For instance, above-mentioned supply-water pump 370 calculates the time of supply-water pump 370 work after (t2) time point is started working, stop the work of supply-water pump 370 behind the certain hour at (t3) time point.At this moment, stop time point (t3) that supply-water pump 370 works on just with vertical cylinder 351 in water level to reach the time point (t3) of peak level consistent.
Below, in conjunction with the flow chart of the summary of Fig. 7, the method for controlling water level of steam raising plant of the present invention is described.As shown in the figure, the method for controlling water level of steam raising plant is by steam generation stage (S310), identification lowest water level stage (S320), water supply stage (S330), identification peak level stage (S340) and stop the water supply stage (S350) and form jointly.
The above-mentioned steam generation stage (S310) is to show heater 352 supply power supplys, and heating vertical cylinder 351 makes its inner water surface produce the stage of steam.At this moment, heater 352 is the outer cylinder lower end parts that are arranged at vertical cylinder 351, the lower end part of heating vertical cylinder 351.The steam that takes place discharges by steam discharge device 354 after heating cylinder 351 pressure inside acquire a certain degree.During the generation steam, the water levels in the heating cylinder 351 progressively reduce, and meanwhile the temperature of vertical cylinder 351 then progressively rises.
In the above-mentioned identification lowest water level stage (S320), be meant that the temperature of identification vertical cylinder 351 reaches the stage of setting maximum temperature.That is, when the water level of heating cylinder 351 is lower than the tip position of heater 352, the temperature of heating cylinder 351 will rise rapidly, thereby reach the highest design temperature.The highest above-mentioned design temperature is after method is determined by experiment, just by in the memory of typing controlling organization 390.When the temperature of above-mentioned heating cylinder 351 reaches the maximum temperature of setting, the temperature measuring set 357 that is arranged at heating position, cylinder 351 upper end will send and the corresponding electronic signal of temperature that heats cylinder 351 to controlling organization 390, thereby identification reaches the situation of lowest water level.
In the above-mentioned water supply stage (S330), be meant that controlling organization 390 starts supply-water pump 370, to the stage of heating cylinder 351 inner supply water.That is, when supply-water pump surpasses the highest design temperature in the temperature of heating cylinder 351, will be activated, to prevent to heat the lowest water level that water levels in the cylinder 351 are lower than setting.At this moment, the both continuous operations within a certain period of time of above-mentioned supply-water pump 370 also can sharply reduce in order to prevent the water temperature that heats in the cylinder 351, and discontinuity work.Discontinuity supply water the time, 352 of heaters continue the supply electric currents like this, just can successional generation steam.
Peak level cognitive phase (S340) is to be formed by the working time of measuring supply-water pump 370.That is, even supply water toward heating cylinder 351 inner continuing, but the temperature of heating cylinder 351 is not with the corresponding proportional reduction of amount of makeup water.So if be the work of benchmark control supply-water pump 370 with the temperature of heating cylinder 351, the water level of heating cylinder 351 causes taking place the possibility that the hot water splash is come out with too high.So the present invention utilizes timer 391, discern the peak level of heating cylinder 351.That is, calculate the working time of supply-water pump 370, the working time that surpasses setting just stops the work of supply-water pump 370, thereby makes water level inside be no more than the peak level of setting.At this moment, setting-up time need consider to heat the area of section of cylinder 351 and the displacement volume of supply-water pump 370 is determined.The setting-up time that stores in time that the supply-water pump 370 that above-mentioned controlling organization 390 measures by comparison timer 391 is worked and the memory discerns whether reach peak level.
At last, above-mentionedly stopping the water supply stage (S350), be to reach setting-up time by 370 working times of supply-water pump that timer 391 is measured, thereby identification reaches the situation of peak level, interrupts the work of supply-water pump 370, stops the stage of water supply in heating cylinder 351.
In sum, utilization of the present invention is arranged at the temperature measuring set 357 of heating cylinder 351 outsides and timer 390 and supply-water pump 370 and regulates water level in the heating cylinder 351, so just need in heating cylinder 351, floodometer or temperature sensor be set, thereby make simplifying the structure of heating cylinder 351, its size can be minimized.In addition,, can continuity produce steam, so even if also can continual enjoyment sit smoked under the situation that many people use because of periodically in small-sized heating cylinder 351, supplying water.Particularly,, therefore also have the user and need not too much to wait for the smoked characteristics of sitting of just can enjoying so the time that initial stage steam produces shortens greatly because use small-sized heating cylinder 351.In addition, supply water by supply-water pump 370 controls, so can omit the water supply control valve door.In addition, can be by controlling the generation of steam, so just can dispense the by-pass valve control that plays the effect of steam regulation amount to the mode of heater 352 supply electric currents.
Next, describe with reference to the flow chart of Fig. 8 control method steam raising plant of the present invention.At first, the heater 352 generation steam of starting working, the temperature of temperature measuring set 363 measuring vertical cylinders 351 sends signal to controlling organization 390,390 of controlling organizations compare with the highest design temperature that is stored in the memory, and whether identification reaches maximum temperature.If the temperature of vertical cylinder 351 reaches the highest design temperature, just start supply-water pump 370 water supply starts.
Supply-water pump 370 is worked at the beginning, and the working time of just utilizing timer 391 to calculate supply-water pump 370, whether identification reaches the time of setting.If also do not arrive setting-up time, then supply-water pump 370 works on.At this moment, controlling organization 390 can successional startup supply-water pump 370, also can be with the certain hour startup supply-water pump 370 of discontinuity at interval
The working time of above-mentioned supply-water pump 370 is interrupted the work of supply-water pump 370 when reaching setting-up time.At this moment, 390 pairs of timers 391 of controlling organization 370 working times of supply-water pump that measure and setting-up time that is stored in memory compares.Above-mentioned setting-up time is to consider the discharge capacity of the area of section of vertical cylinder 351 and supply-water pump 370 and be fed to the experiment value that the factors such as voltage of heater 352 are determined.
In addition, as shown in Figure 6, under the interrupted situation of the work of supply-water pump, within certain postponement time (as 5 minutes),, can not start supply-water pump even reached the lowest water level standard according to vertical cylinder 351 temperature of temperature sensor 363 identifications yet.This is in order to prevent under the state that reaches peak level, because of the temperature of vertical cylinder does not in time reduce, thereby is mistaken for lowest water level and the situation that continues to supply water takes place.
