The second temperature.
The control module 126 is used for according to the 3rd temperature and the 4th temperature, calculates the temperature change of the cooking cavity 118
Value.
In present embodiment, illustrate as an example, the first temperature is 60 DEG C, second temperature is 80 DEG C.Control module
By the first temperature sensor 108,126 judge that the temperature of water container 114 reaches the first temperature (such as 60 DEG C), control module
126 record second temperature sensors 110 measure the 3rd temperature of cooking cavity 118.
Subsequently, heater control module 122 can control 116 heating with full power water container of heater, the first temperature sensor
108 temperature for measuring water container 114 are continuously increased, and second temperature sensor 110 detects the temperature of cooking cavity 118 and can also follow
Increase, now, when control module 126 judges that the first temperature sensor 108 detects the temperature of water container 114 and reaches second temperature
When (such as 80 DEG C), control module 126 goes to record the 4th temperature that second temperature sensor 110 measures cooking cavity 118, control again
Molding block 126 deducts the 3rd temperature using the 4th temperature, just can obtain the temperature in water container 114 and rise to second from the first temperature
The temperature change value of the cooking cavity 118 of (as 60 DEG C rise to 80 DEG C) during temperature.
For example, Fig. 3 please be join, under normal circumstances, the 3rd temperature is T1 to the water yield of water container 114, and the 4th temperature is T2, T2-
T1 is that cooking cavity 118 rises to the temperature change value of second temperature in the temperature of water container 114 from the first temperature.
Usually, the water yield that water container 114 is accommodated up to can reach 400ml.During work, the water yield one of water container 114
As control between 50ml～100ml, in this case, the steam generator 102 of a 1800W, in the first TEMP
Device 108 measures the temperature rising that will produce water vapour when the temperature of water container 114 reaches 60 DEG C by cooking cavity 118.Therefore, exist
The water yield of water container 114 under normal circumstances, when the temperature of the water container that the first temperature sensor 108 is measured reaches 80 DEG C, one
The temperature of the cooking cavity 118 of individual 26L can rise 13 DEG C～15 DEG C (differences i.e. between the 3rd temperature and the 4th temperature).
But, if the water yield in water container 114 reaches maximum, i.e. 114 water of water container completely, then (it is filled with water in this process
The temperature of device rises to 80 DEG C from 60 DEG C) in, control module 126 judges the temperature of cooking cavity 118 by second temperature sensor 110
Degree changing value only has 1 DEG C, even more little.For example, Fig. 3 please be join, in the case of the hypervolia of water container 114, the 3rd temperature is
T1 ', the 4th temperature rise to second temperature in the temperature of water container 114 from the first temperature for cooking cavity 118 for T2 ', T2 '-T1 '
Temperature change value.
It is pointed out that the concrete numerical value of above-mentioned data can be from theoretical calculation during product design and various realities
Checking gained, the theoretical calculation of data can be calculated with heat of vaporization, specific heat capacity and environment temperature of water etc. is crossed, unknown here
State, those skilled in the art can specifically be calculated with reference to description of the present embodiment and test.In general, theoretical calculation
Result out needs the actual design with product, such as heat dispersal situations, and temperature sensor location etc. combines checking.
Therefore, during control module 126 rises to second temperature in the temperature of water container 114 from the first temperature, sentence
After the temperature change value subnormal temperature scope (13 DEG C～15 DEG C) of disconnected cooking cavity 118, then the water in water container 114 is described
Excessive, control module 126 starts an only heating of not supplying water when 114 temperature of water container exceed second temperature
Control logic, the duration of this control logic, typically by power and the cooking cavity that actually measures of heater 116
The degree that 118 temperature change value reduces than normal temperature change value is determining, for example, (heater in previous example
116 power are 1800W), when the temperature change value of the cooking cavity 118 for measuring only has 10 DEG C, the water yield mistake of water container 114 is described
Many, according to following development Experience formula：T=(Ts-Tr) * TC, confirms the duration.Wherein, T represents the duration, that is, close
Close the water supply installation 106 and control the duration of 116 continuous heating water container 114 of heater, Ts represents the preset value, Tr table
Show the temperature change value of the cooking cavity 118, Tc represents time adjustment coefficient.
For above example, water container 114 the water yield under normal circumstances, the temperature change value of cooking cavity 118 should
It is 14 DEG C.Therefore, in this example, preset value is 14 DEG C.But, in fact, control module 126 passes through second temperature sensor
The temperature change value of the cooking cavity 118 that 110 measure is 10 DEG C, and this illustrates the hypervolia of water container 114.Time adjustment coefficient
It is to be calculated and be adjusted obtaining by actual experiment with reference to the heat of vaporization (2250J/g) of water according to the design of product, above-mentioned
In example, this coefficient is 10s/ DEG C, so, control module 126 controls when the temperature of water container 114 exceedes second temperature
Water supply installation control module 124 is closed water supply installation 106 and controls heater 116 persistently to add by heater control module 122
Hot water container 40 seconds, the water allowed in water container 114 evaporate rapidly minimizing.After when 40 seconds in the past, bottom type steam raising plant 100
Work on by normal control logic.
In above-mentioned control process, the change of each temperature sensor and the control of water supply installation 106 and heater 116 can be joined
Examine shown in Fig. 3.Fig. 3 respectively show, and the temperature curve of the cooking cavity that second temperature sensor 110 is detected is (including water container 114
Water yield temperature curve under normal circumstances, in the case of the hypervolia of water container 114 after only heating adjustment of not supplying water
The temperature curve not adjusted in the case of the hypervolia of temperature curve and water container 114), the first temperature sensor 108 detects
Control sequential E1, E2 of temperature curve, control sequential H1 of heater 116 and water supply installation 106 of water container 114 (include
Control sequential E1 of the water level of water container 114 shown in solid water supply installation 106 under normal circumstances, and being filled with water shown in dotted line
Control sequential E2 of the water supply installation 106 in the case of the water level of device 114 is excessive).
From the figure 3, it may be seen that in the case of the hypervolia of water container 114, after only heating adjustment of not supplying water, cooking cavity
Temperature curve is closer to the water yield temperature curve under normal circumstances of water container 114 so that bottom type steam raising plant 100
Operation more reasonable, can larger play the thermal efficiency of water container 114, improve cooking speed.
In present embodiment, the bottom type steam raising plant 100 includes timer 128, and the timer 128 connects the control
Device processed 112.Controller 112 is used for, when the heating water container 114 of heater 116 is opened, controlling 128 timing of timer.
Specifically, timer 128 is the count-down device of of bottom type steam raising plant 100 itself.Timer 128 can be with controller 112
Integrate.Timer 128 starts countdown after product culinary art comes into operation.At the end of countdown, cooking time is tied
Bundle, control module 126 control water supply installation control module 124 to close water supply installation 106, and control heater control module 122
