Description
Technical field
The present invention relates to energy-saving steam cabinet field more particularly to a kind of commercial gas premix full ratio control energy-saving steam cabinet and its
Control method, with full premix combustion high thermal efficiency, intelligent power saving management control, combustion power is adjustable setting and safety failure
Self-test and the function of reporting failure.
Background technology
Commercial gas steamer is ordinary strong exhaust band blowout protection Combustion System currently on the market, and the thermal efficiency generally only has
50% or so, when burning, is the largest always combustion power burning, when steam heat reaches balance, just will produce remaining combustion
It burns, the combustion thermal efficiency of another forced-ventilated burning is not high, wastes a large amount of fuel, high so as to cause use cost.Additionally
It has the following problems：
First, the blowout protection of the preceding kitchen range of commercial gas on the market ignition controller and commercial gas steamer ignition controller
Technology is all the technically simple application of household gas apparatus ion detection, is not suitable for commercial use environment.
The high-tension ignition energy ratio household of commercial gas kitchen tools ignition controller it is two 3 times big, damage to controller and
Interfere probability much larger；Commercial gas kitchen tools use environment is moist, and ionic current easily leakage causes fire defector sensitivity low, accidentally
Report flare up fire；Fire defector needle and high-tension ignition needle are all separate from, and while installing will have larger separation distance, no
High pressure of then lighting a fire climbs electricity and causes ignition control circuit to damage or be disturbed to fire defector needle, causes combustion gas largely to leak and pacifies
Full accident problem；Or fire defector needle and high-tension ignition are directed to point and form fire defector circuit, are not big with burner housing
Ground forms detection and returns, and igniting high pressure is not released well when igniting, so that high pressure is transmitted to kitchen along combustion flame by frying pan
Shi Zaocheng has the feeling of numb electricity.
The flame detection circuit of existing market commercial gas ignition controller is all to transplant domestic gas appliance flame detection circuit
It uses, causes control circuit control unstable or damage, influence the normal use of commercial kitchen tools, until existing commercial kitchen tools is made all to be reluctant
Meaning uses ion blowout protection, gives commercial kitchen tools that very serious safe handling problem, each place combustion gas association is brought to force in this way
Country can not be executed to hotel industry gas-fired kitchen safety management.
Second, commercial steamer is all to utilize low-voltage dc voltage to water level detecting on the market, this detection mode can be because of direct current
Voltage, which is added on water level detecting needle, generates ionization chemical action, and water level detecting needle is made quickly to adhere to incrustation scale.Due to the resistance of incrustation scale
Greatly, when the amount of scale of water level detecting wire surface attachment is excessive, conductive current will be very low, and detection circuit is caused to can't detect electricity
Pulse can not be detected having water.Incrustation scale can also promote electrochemical corrosion to aggravate, and water level detecting wire surface is caused to corrode,
The damage of heating surface is accelerated to shorten its service life to reduce the detection accuracy of water level detecting needle.Further, since water body
When high-boiling evaporates, fluctuation is very big up and down for the water surface, easily leads to the flase drop of water level, ultimately causes dry combustion method and damage water tank.
Third, at present commercial gas kitchen range ignition controller and commercial gas steamer ignition controller on the market, combustion gas
Electromagnetic switch valve-driving circuit is all directly to use low and high level type of drive, this type of drive dead by external interference in MCU
Combustion gas electromagnetic switch valve, the safety problem for causing combustion gas to leak for a long time can be opened after machine for a long time.In addition, combustion gas electromagnetic switch valve exists
Afc voltage 24V or more works long hours, combustion gas electromagnetic switch valve because of the excessively high damage of temperature, can cause the maintenance cost of equipment compared with
Height, use cost increase.
In high temperature, wet environment when now the ignition controller of commercial combustion gas kitchen tools in the market is because using, due to igniting
Energy is big and interferes the reasons such as big, leads to not to be arranged safety protection mechanism, and there are prodigious security risks when use.

Cabinet saves at least 60% fuel, and the expense saved every year is very considerable, and more safer than general commercial gas combustion steaming cabinet；
2, using steam circulation recovery technology, fuel 70% is saved to greatest extent, reaches energy-efficient purpose；
3, rotation speed of fan FL and big when rotation speed of fan FU, the output of small fire ratio when the output of kindling material ratio can be arbitrarily arranged in MCU
Gas outlet amount can be arranged according to the combustion power of burner in three rotation speed of fan such as rotation speed of fan FH when fiery ratio output,
Extra combustion power caused by being unworthy of of device configuration can be reduced, reaches power conservation requirement；
4, electromagnetic switch valve control driving circuit ensures that controller will not be because of MCU using the isolation control of 500HZ pulsed capacitances
Unexpected crash causes to be opened accidentally solenoid valve and cause gas leakage；
5, ionic flame detection blowout protection circuit has many advantages, such as anti-interference strong, high sensitivity；
6, wind turbine uses frequency controlling fan, wind turbine to have rotating speed output, MCU directly to be closed as when judging rotation speed of fan exception
System is closed, ensures that equipment will not occur in combustion failure or contingency caused by fan trouble；
7, pulsed exchange water level detecting technology is used, low-voltage micro-current of alternation pulsing detects signal, reduction water level
Needle fouling caused by direct water solution is detected, the service life of water level detecting needle is extended；When low water level water shortage, water is boiled because of water
Surface wave is dynamic to make water level detecting needle flase drop signal, but MCU inspections are not judged as there is water, ensure that not less than 50Hz/ pps pulse per second signals
Sentencing because of water level flase drop leads to dry combustion method；
8, by water level detecting needle it is alternating impulse voltage, ionization is only just will produce 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
