In a specific embodiment of the present invention, remaining treatment time of water t includes：Residue in steam generator 20
Remaining evaporation of water time t2 in evaporation of water time t1 and the pipeline between public valve port 401 and steam generator 20.
After 40 power-off of three-way valve, small part water may be also had on steam generator 20 and is not evaporated, meanwhile, public valve
Water between mouth 401 and steam generator 20 in pipeline can be also flowed on steam generator 20, therefore remaining treatment time of water t etc.
In t1 and t2 sums.
The foundation that remaining treatment time of water t determines is：Heat energy used by evaporation 1g water is 2256J, if the work(of heat-generating disc
Rate is 1800W (can provide 1800J heat energy in i.e. 1 second), then, evaporation 1g water uses the 1.2-1.3 seconds.Then, according to three-way valve
The length and caliber of the pipeline between 40 and steam generator 20, calculating know remaining how many grams of water, are multiplied by 1.2- with the water yield
Just the remaining treatment time of water that theoretical minimum can be obtained in 1.3 seconds.In fact, when three-way valve 40 is closed, steam generator 20
On might have small part water and also do not evaporate, therefore the remaining treatment time of water of reality can be than above-mentioned residual water in theory at
The reason time is bigger.When the temperature of steam generator 20 far surpasses 100 DEG C, for example the temperature of steam generator 20 is 160 DEG C, then steam
The water electrode not being evaporated on vapour generator 20 is few, therefore is negligible；When the temperature of steam generator 20 is 100 DEG C -110
DEG C, then the water not being evaporated on steam generator 20 can be more.Therefore the control steam generator 20 of control unit 70 can be made with
Higher temperature operation, makes water be evaporated as early as possible, to allow actual remaining treatment time of water closer to theoretic minimum remnants
Treatment time of water.
For example, if there is the water of 5g in the pipeline between public valve port 401 and steam generator 20, steam generator 20 exists
The water less than 1g is remained during 40 power-off of three-way valve, the quantity of residual on steam generator 20 has 6 grams.It is certain for power
Steam generator 20 (can be set as 1800W), needs continue on the 8-9 seconds after three-way valve 40 is closed could be by steam generation
Water in device 20 all evaporates.
In a specific embodiment of the present invention, between S3 steps and S4 steps, also including S5：When detecting steaming
Temperature M of vapour generator 20, and be compared with preset value m, as M >=m, return to step S4；As M ＜ m, step is returned to
S3。
Specifically, in steam cooking apparatus 100, temperature sensor 60 can also be set, the temperature sensor 60 can be with
The temperature of steam generator 20 is determined, and the temperature sensor 60 is also connected with control unit 70, so as to control unit 70 can
With the temperature information that detects according to temperature sensor 60 to control the running status of steam cooking apparatus 100.Work as steam generation
When temperature M of device 20 exceedes preset value m, preset value m is usually the maximum heating temp allowed by steam generator 20, temperature
The temperature information is fed back to control unit 70 by sensor 60, and control unit 70 then can send control steam according to the temperature information
The signal that generator 20 cuts out.
Before culinary art terminates, when being processed according to determined by the watt level (evaporating the ability of water) of steam generator 20
Between come arrange in advance close three-way valve 40 time, in the above example, steam generator 20 process residual water need the 8-9 seconds,
The time that three-way valve 40 then can be closed in advance is set as 15 seconds, that is, remaining treatment time of water t is set as 15 seconds.When
After residual water is all evaporated by steam generator 20, within the time of follow-up 6-7 seconds, the temperature of steam generator 20 may proceed to
Rise, the temperature can exceed preset value m, the temperature information that control unit 70 can be detected according to temperature sensor 60 sends
The signal of steam off generator 20 is no longer generated heat with steam off generator 20, steam generator 20, to prevent steam generation
20 dry combustion method of device.
Thus, even if the remaining treatment time of water t of setting is more than actual remaining treatment time of water in control unit 70,
By after residual water evaporating completely, control unit 70 can be detected to steam generator 20 steam generator 20 according to temperature sensor 60
To temperature information to make the signal of timely steam off generator 20, so as to steam generator 20 will not produce it is overheated and dry
The hidden danger of burning, and steam generator 20 can fully by residual water evaporating completely.By control unit 70 and temperature sensing
Device 60 control operation and closing of the steam generator 20 in remaining water treatment procedure state, enhance the intelligent of control and
Accuracy.
