Beneficial effect
Compared with prior art, the advantages of the commercial steamer alternation pulsation water level detecting system of the utility model are as follows:
1, by water level detecting needle it is alternating impulse voltage, ionization only can be just generated in pulse wave crest, and ionize
Part is concentrated mainly at the needle point of water level detecting needle, and the magnesium ion that water level detecting needle is generated by electrolytics effect is greatly decreased
Scale being generated with combinations such as calcium ions in water to be attached on water level detecting needle, water level detecting wire surface resistance is small, and conductive current is big,
Reduce surface corrosion caused by scale simultaneously, not only improves the accuracy of detection of water level detecting needle, but also substantially extend it to make
Use the service life；
If 2, MCU receives frequency of the water level detection circuit through water level detecting needle to its pulse signal fed back, with water
The frequency for the fixed frequency pulse electric current that position detection circuit is exported to water level detecting needle is identical, then has been determined with water, has been otherwise nothing
Water, detection structure is very accurate, avoid the occurrence of quantity of water in water tank it is few when because explosive evaporation cause the water surface up and down fluctuate make
It is still the erroneous detection situation for having water at water level detecting；
3, heating system and water inflow control system are uniformly controlled by MCU, also can be automatically controled water tank without human intervention
Interior water level fluctuates in the normal range, guarantees that water tank will not be damaged because of dry combustion method.
Through the following description and in conjunction with the attached drawings, the utility model will become more fully apparent, these attached drawings are for explaining this
The embodiment of utility model.
