Convenient can be according to specific jam condition, in time remind the user to clear up filter screen in the water supply connector, avoid blockking up, extensively be applicable to various types of gas heater or electric water heater.
Description
Technical field
This utility model relates to fluid heater technical field, particularly relates to a kind of water heater drainage screen cleaning alarm set.
Background technology
Existing water heater is in use, neither one accurately and timely method reminds user to clear up water supply connector place drainage screen, if water heater does not clear up water supply connector place drainage screen for a long time, water heater discharge reduction can be caused, affect user to take a shower comfortableness, because the water yield is very few causes dry combustion method, gas heater can be damaged time serious.
Utility model content
For problems of the prior art, the purpose of this utility model is in that to provide a kind of water heater drainage screen cleaning alarm set, reminds user to clear up drainage screen in water supply connector, it is to avoid blocking.
For reaching object above, this utility model adopts the following technical scheme that.
A kind of water heater drainage screen cleaning alarm set, it is characterised in that including: controller, be arranged on the pressure transducer before and after water heater drainage screen and reminding alarm device；Described controller is connected with pressure transducer, reminding alarm device signal, and the signal provided according to pressure transducer controls reminding alarm device work.
As further illustrating of above-mentioned cleaning alarm set, described controller is water heater master controller.
As further illustrating of above-mentioned cleaning alarm set, described reminding alarm device is one or more in display, display lamp, buzzer, sound broadcasting device.
As further illustrating of above-mentioned cleaning alarm set, described drainage screen is arranged in the water supply connector of water heater.
As further illustrating of above-mentioned cleaning alarm set, described water heater is gas heater or electric heater.
Compared with prior art, a kind of water heater drainage screen cleaning alarm set that this utility model provides, according to concrete stopping state, can remind user to clear up drainage screen in water supply connector in time, avoid blocking, be widely used in various types of gas heater or electric heater.
Accompanying drawing explanation
Fig. 1 show the water heater structure schematic diagram that this utility model provides；
Fig. 2 show cleaning and reminds control principle drawing.
Description of reference numerals:
1: controller, 2: drainage screen, 3: the first pressure transducers, 4: the second pressure transducers, 5: reminding alarm device.
Detailed description of the invention
It is more fully understood that essence of the present utility model for convenience of those skilled in the art, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As it is shown in figure 1, a kind of water heater drainage screen cleaning alarm set, it is characterised in that including: controller 1, be arranged on the first pressure transducer 3 of water heater drainage screen 2 front end, be arranged on the second pressure transducer 4 of drainage screen 2 rear end and reminding alarm device 5；Described controller 1 is connected with first pressure transducer the 3, second pressure transducer 4, reminding alarm device 5 signal, and the signal provided according to first pressure transducer the 3, second pressure transducer 4 controls reminding alarm device 5 and works.Here, drainage screen 2 is arranged in the water supply connector of water heater, and the front and back end of drainage screen 2 judges with the direction that intakes as foundation, and the water inlet current first place of flowing through is front end, and after water inlet current, the place of flowing through is rear end.
For the structure of compact device, in the present embodiment, it is preferable that controller is water heater master controller, it is preferable that reminding alarm device is display floater.In other embodiments, described controller is independent controller, and described reminding alarm device is one or more in display, display lamp, buzzer, sound broadcasting device, is not limited to the present embodiment.
A kind of water heater drainage screen cleaning alarm set that the present embodiment provides can be used on various types of gas heater or electric heater.
Concrete control principle as in figure 2 it is shown, when cold water flows through water supply connector drainage screen place, pressure transducer induction pressure P before and after drainage screen1、P2, and force value is sent to master controller carry out pressure differential judgement, work as P1-P2<PFixed 1(PFixed 1For the lower limit of hydraulic pressure difference that master controller sets), master controller is judged to normal operation, when impurities in water increase gradually cause that drainage screen blocks time, P2Decline, P1-P2Difference increasing, work as P1-P2>PFixed 1Time, master controller is judged as blocking, and on display floater, " cleaning " prompting is lighted, and reminds user that drainage screen is manually cleared up.
User needs first to close water valve before clearing up drainage screen, after having cleared up, boiled water again, master controller can judge again, if normally, " cleaning " prompting can disappear automatically.
If user clears up always, main control calculates difference P1-P2>PFixed 2(PFixed 2Higher limit for the hydraulic pressure difference that main control sets) time, master controller is then judged as that blocking is serious, for avoiding machine and the person are caused damage, master controller can actively cut off gas valve for gas water heater or electric heater power supply, on display floater, " cleaning " prompting can continue to glimmer from lighting to become, this phenomenon until cleaning drainage screen complete after again boiled water just can disappear.
One as above-mentioned method for cleaning converts embodiment, and described reminding alarm device includes display floater and buzzer, and when the actual hydraulic pressure difference calculated is more than the differential water pressures lower limit set, on display floater, " cleaning " prompting is lighted；When the actual hydraulic pressure difference calculated is more than the differential water pressures higher limit set, Mel device sends chimes of doom.
Another kind as above-mentioned method for cleaning converts embodiment, and described reminding alarm device includes display floater and sound broadcasting device, and when the actual hydraulic pressure difference calculated is more than the differential water pressures lower limit set, on display floater, " cleaning " prompting is lighted；When the actual hydraulic pressure difference calculated is more than the differential water pressures higher limit set, sound broadcasting device sends chimes of doom.
Essence of the present utility model has been described in detail by above detailed description of the invention, but with this, protection domain of the present utility model can not be limited.It should be evident that under the enlightenment of this utility model essence, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that these improve and modify and all drop within claims of the present utility model.
