It should be noted that the steamer 100 that the present invention is provided includes above-mentioned electric-control system 200, do not carried in the present embodiment
And other parts content, it is identical with first embodiment, repeat no more here.
In addition, the electric-control system 200 for being provided in the present embodiment can be also used for miscellaneous equipment.Such as, full premix is fried
Stove.For frying during stove, the electric-control system 200 can omit water level detecting function and vapor (steam) temperature detection function.Set for other
When standby, it is also possible to suitably increase or decrease functional module according to actual conditions, the substitutability between each functional module can be very
By force, can be easy to operate with flexible combination, it is applied widely, with great application value.
Steamer 100 and electric-control system 200 that the present invention is provided, its operation principle are as follows：
The switch of electric-control system 200 is opened, frequency conversion fan 150 is opened about 20 seconds, by the residual gas in air supply duct
Emptying, prevents tempering.Then the control of processing module 210 igniter fire, proportioning valve are opened, and combustion gas are connected, by combustion gas and air
Mixed gas be transported to burning jamb 1115 through air supply duct.Gas burning produce flame, if fire prospecting needle detect flame it
Afterwards, signal is sent to processing module 210, processing module 210 sends instruction, circulation electricity after receiving the signal to circulation motor 131
Machine 131 is opened, and steam enters circulation pattern.If fire prospecting needle is not detected by flame, i.e. gas unburned, without flame when, proportioning valve
Close, frequency conversion fan 150 works on, the residual gas in emptying pipeline.Continue to light a fire after reset key is pressed, until visiting
Fiery pin detects flame.
Gas burns, the water heating to the first water tank 111, to produce steam, whole accommodating sky of the steam full of cabinet 120
Between 123.Circulation motor 131 is opened, and steam is sucked into recovery channel 137 from the air inlet of recovery channel 137, reaches circulation motor
131 air inlet, reaches discharge line 135, most afterwards through the steam vent on discharge line 135 through the gas outlet of circulation motor 131
1351 return in the accommodation space 123 of cabinet 120, go round and begin again, and form steam circulation.
Level electrode 1131 on second water tank 113 is electrically connected with processing module 210, when level electrode 1131 detects water
When position is less than preset water level threshold value, signal is sent to processing module 210, request adds water, the control water inlet pipe 115 of processing module 210
Valve 1151 open, add water toward the second water tank 113.When level electrode 1131 detects water level higher than preset water level threshold value
When, signal is sent to processing module 210, request stopping is added water, and the valve 1151 of the control water inlet pipe 115 of processing module 210 is closed,
Stop adding water toward the second water tank 113.
By the control panel 171 of the lower section of cabinet 120, it is believed that input sets flame temperature, mixture ratio, gas transmission
The parameters such as speed.For example, the preset temperature of flame is set to 100 DEG C, when thermocouple detects flame temperature higher than default temperature
During 100 DEG C of degree, thermocouple sends temperature signal to processing module 210, and processing module 210 is received combustion system after this signal
Small fire pattern is automatically changed to, the automatic frequency for changing frequency conversion fan 150 reduces rotating speed；Automatically adjust ratio valve opening, reduce into
Tolerance.Conversely, when thermocouple detects flame temperature less than 100 DEG C of preset temperature, thermocouple sends temperature to processing module 210
Combustion system is automatically changed to big fire pattern, frequency conversion fan is changed automatically by degree signal, processing module 210 after receiving this signal
150 frequency, increases rotating speed；Ratio valve opening is automatically adjusted, increases air inflow.
To sum up, the present invention is provided steamer 100 and electric-control system 200 have the beneficial effect of the following aspects：
