The major function of the full-automatic boiling water water system of the utility model includes:
Have standard time clock and show (time several months that has a power failure is still accurate); Show water temperature and water level in main water box and the diversion box in real time; Having the automatic or manual mode of operation can switch at any time, is provided with water tank dry combustion method, lack of water multiple protective program, goes up water by magnetic valve or water pump control; Can set the water level of water; But the fault of intelligent decision internal system is also in time reported to the police, and makes between control cabinet and the water and can realize Long-distance Control.
Have in 24 hours random times, 2 temperature, 5 Water Level Control, have running status and setup parameter that LCDs is used for display system.If abnormal phenomenon has appearred in hydraulic pressure, draining valve or sensor in the water tank, system will automatically switch to the mode of operation of manual control.
This system adopts the industry control Single-chip Controlling, has the functional reliability height, and heating-up temperature and heat time heating time in the water tank all can be set arbitrarily.Owing to adopted contactless control mode, so system has long service life, and controllable power is big, can not need peripheral components such as contactor.For example adopt three road 26A high-power silicon controlled rectifiers, can use three-phase and four-line, phase three-wire three, the AC power of phase line.
When native system adopted the 380V three-phase alternating-current supply, actual controllable peak power output can reach 15Kw; When native system adopted the 220V single phase alternating current power supply, actual controllable peak power output can reach 9Kw.
Native system has also adopted zero passage to open and the zero-crossing switching technology, can reach noiseless, the purpose that computer work is reliable and stable.Owing to be provided with fuse link in this system, just in case short circuit or overload problem occur, fuse at first can fuse, and have only after the fault eliminating, and system just can rework after changing fusible link.
The 24V dc source is adopted in the power supply of each diversion box in native system, can avoid the special circumstances such as aging, humidity of equipment to cause the electric leakage problem like this.Each diversion box of native system all adopts dual hardware controls simultaneously, has therefore further increased the reliability of system works.
The concrete course of work of the full-automatic boiling water water system of the utility model is as follows:
1, after running water enters the main water box of sealing under the control of single-chip microcomputer, after reaching the setting water yield, just begin to add hot water, if the water yield in the water tank is lower than 40% and does not add hot water, delayed time again 0～60 minute after by electric heater water being heated to 95 ℃, with ultraviolet disinfecting tube the water in the water tank is carried out disinfection simultaneously.If water tank occur to leak water level is dropped to less than after 40%, system can automatic water supplement to beginning heating again greater than 40%, if mended in 30 minutes less than greater than can the demonstration water yield in 40% display low excessively; Can set 0～240 minute and be the longest time that adds hot water, its default value is 120 minutes.Both just in case level sensor damages, must stop in 120 minutes to the longest hot water that adds, and show that adding hot water made mistakes, the minimum time that adds hot water is 60 minutes.Delay time 0～60 minute after water is heated to 95 ℃ again to guarantee that the water yield enough opens, also can guarantee under the inner hypobaric situation of water tank, still can be with water boiled and be unlikely to not stop, time-delay can only be set at 0～60 minute; If water level drops to less than 20%, moisturizing to after 40%, heating again.If mended less than greater than 40%, and can show that the water yield was low excessively in 30 minutes; If water temperature drops to less than 60 ℃, temperature can be mended automatically to 80 ℃ by system, and shows that water temperature is low excessively.Heating stops during moisturizing, and water is heated to after the boiling water supply start again.
Behind the water ebuillition of heated, at first can automatically water temperature be cooled off by cooling fan, be cooled to and drink design temperature, and then water is entered in each diversion box, wherein the coolant water temperature value can be set at 30 ℃～60 ℃ and promptly can drink.
And each diversion box also can be controlled water temperature and water supply automatically, and water temperature is crossed when hanging down can be heated to design temperature automatically, can stop when water temperature is too high supplying water, in order to avoid scald.Its water temperature can be different and set suitable water temperature at season.
2, the utility model is all made totally enclosed type with the boiling water system in all pipelines of water outlet of intaking, to avoid secondary pollution or cross pollution.
3, the water of not drunk can be discharged by the setting-up time system every day, water tank can clean 10 minutes with ultrasonic cleaner in system before draining, carry out blowdown then and handle.Cleaning back draining to 20% delayed time 20 minutes again; Can set 0～240 minute and be that the longest water discharge time, its default value are 120 minutes.Both just in case level sensor damages, must stop in 120 minutes to the longest draining, and show that draining made mistakes, minimum water discharge time is 60 minutes.
Go up water after the draining and stop to setting the water yield, can set the longest upward water time is 0～240 minute, and its default value is 120 minutes; Both just in case level sensor damages, must stop to go up water in 120 minutes to the longest upward water, display shows that going up water makes mistakes simultaneously, and can set minimum upward water is 60 minutes.
4, cause water temperature too high in order to prevent cooling system from breaking down, reload temperature control device on the flowing water Valve of each diversion box stops water outlet, with the anti-scald drinking person when water temperature surpasses design temperature.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
