In order to ensure the response sensitivity during adjustment heating firepower of heating unit 30, the control range of above-mentioned threshold value of uncapping
At -20 DEG C~-5 DEG C, by set it is rational uncap threshold value and recording unit 21 records the time interval of detection temperature, can be with
When open pot lid action, the heating unit 30 of electric cooker can be responded enzyme rapidly and sensitively the electric cooker made, make electric cooker
The adaptive function of heating firepower is better achieved.
In order to enable the firepower of electric cooker to be well controlled, the mouthfeel of electric cooker cooked food, heating dress are lifted
Heating firepower and the ratio of the heating firepower after lifting level-one before putting 30 lifting level-ones are 1/16~1/2.Realize and adjust
The mode of the heating firepower of heating unit 30 can change the heating power of heating unit 30.For example, heating unit 30 is lifted
Heating power before level-one is 100W, and the heating power after lifting level-one is 1600W；Or heating unit 30 lifts level-one
Heating power before is 1000W, and the heating power after lifting level-one is 2000W.In the present embodiment, heating unit 30 carries
The ratio of heating power and the heating power after lifting level-one before rising level-one is 1/16~1/2.By reasonably setting
Heating unit 30 lifts the heating power before and after level-one, when can make it that the control heating unit 30 of control module 20 is heated,
Be not in that firepower is suddenly big or suddenly small, gradually change with realizing heating firepower.
It should be noted that in certain embodiments, adjusting the mode of the heating firepower of heating module 30 can not also use
The mode of above-mentioned 30 heating power of change heating module, but realized pair controlling the Power Regulation of heating unit 30 than by way of
Heating unit 30 heats the adjusting of firepower.Wherein Power Regulation is than referring to when the heating power of heating unit 30 is kept constant, one
In a heating cycle, the heating time of heating unit 30 and the time ratios of heating cycle.For example, the heating work(of heating unit 30
Rate is 2000W, heating cycle 32s, the heating time of heating unit 30 is 16s, and the Power Regulation ratio of heating unit 30 is 16/ at this time
32.In another embodiment of the invention, when controlling heating firepower than by the way of using the Power Regulation of control heating unit 30, add
Heat cycle is 32s, and the heating time that heating unit 30 lifts before heating firepower level-one is 2s~8s, and the lifting of heating unit 30 is heated
Power Regulation ratio before firepower level-one is 2/32~8/32；Heating unit 30 lifting heating firepower level-one after heating time for 16s~
32s, it is 16/32~32/32 that heating unit 30, which lifts the Power Regulation ratio after heating firepower level-one,.At this time, the lifting of heating unit 30 one
Heating firepower and the ratio of the heating firepower after lifting level-one before level are 1/16~1/2.Therefore, through the above way
It can realize the control of the heating firepower to heating unit 30.
Technical solution of the present invention by by the current detection temperature that the temperature detecting module 10 in pot lid detects with it is upper
The temperature gap produced between temperature and threshold value comparison of uncapping once are recorded, when temperature gap, which is less than or equal to, uncaps threshold value,
May determine that electric cooker is uncapped state at this time, and the heating firepower of heating unit 30 lifted level-one, convection current loss of heat amount it is interior
Pot carries out temperature-compensating, realizes electric cooker and is accomplished to heat the adaptive change of firepower according to its temperature change.Meanwhile the present invention
Electric cooker detects the hardware configuration of pot lid uncapped states without other, thus structure is simpler, and production cost is lower.
During electric cooker is cooked congee, in order to realize the process of cooking congee that ought uncap for a long time, electric cooker can be made with stable
Temperature is cooked congee, and the control method of above-mentioned electric cooker further includes after the step of S50：
, will when the detection temperature before current detection temperature is more than or equal to the heating unit 30 lifting heating firepower
The heating firepower of the heating unit 30 reduces level-one.
Specifically, 21 records have the detection temperature before heating unit lifting heating firepower, comparison unit 23 in recording unit
Contrasted when lifting the detection temperature before heating firepower with heating unit 30 to current detection temperature.When current detection temperature is big
When heating unit 30 lifts the detection temperature before heating firepower, the trigger circuit of execution unit 24 is excited, this
When control module 20 send regulating command to heating unit 30, the heating firepower of heating unit 30 is reduced into level-one so that electric meal
The temperature of pot keeps the heating-up temperature of temperature under uncapped state, prevents under uncapped state, and electric cooker is persistently using larger
Firepower is cooked congee, and avoids electric cooker from the situation overflowed occur.
Further, during electric cooker is cooked congee, pot lid is when by uncapping to pass lid state, the temperature in pot lid
The detection temperature that detection module 10 detects can also change, by by above-mentioned temperature gap and pre-set pass lid
Threshold value comparison, the closure state of the pot lid with regard to that can judge electric cooker, while electricity can also further be adjusted according to the temperature gap
The heating firepower of rice cooker, makes electric cooker realize the adaptive change of heating firepower.
As shown in Fig. 2, during the cooking congee of above-mentioned electric cooker, food materials have been added in the action that to electric cooker uncap
Afterwards, when carrying out closing lid action, the control method of above-mentioned electric cooker further includes after the step of S50：
S60, when the temperature gap is more than or equal to and closes lid threshold value, the heating firepower of heating unit is reduced by one
Level.
Electric cooker is in uncapped state, due to needing internal pot temperature to compensate, thus the heating firepower of heating unit
Need to lift level-one, after electric cooker close lid action, since interior pot is in sealing state, the temperature of interior pot starts on constantly
Rise, the detection temperature acquired in temperature detecting module 10 also constantly raises.At this time, current detection temperature value is more than last record
The detection temperature value of unit record, i.e. computing unit 22 subtract the inspection of last recording unit records by current detection temperature value
The temperature gap that testing temperature is worth to be on the occasion of.It should be noted that close lid threshold value be also on the occasion of, be more than when the temperature gap or
During equal to closing lid threshold value, illustrate that temperature steeply rises in electric cooker, it can be determined that go out electric cooker and be in pass lid state.For example,
During a certain moment of electric cooker cooks congee, the temperature gap that the computing unit 22 of control module 20 is drawn is 15 DEG C, and pre-
If pass lid threshold value be 10 DEG C, temperature gap is more than and uncaps threshold value at this time, thus may determine that and show that electric cooker is now in closing
Lid state.When electric cooker, which is in, closes lid state, the trigger circuit of execution unit 24 is excited, and control module 20 is to heating at this time
Device 30 sends regulating command, makes the heating firepower of heating unit 30 reduce level-one, reduces firepower, occurs to the interior pot of electric cooker
The situation of temperature overheating, the phenomenon overflowed with preventing electric cooker from causing since firepower is excessive.
When electric cooker be in close lid state when, if the heating firepower setting of electric cooker is excessive, i.e., heating unit 30 add
Showing tremendous enthusiasm power is higher, is easy to cause interior pot heating comparatively fast, causes cooked food nutrient loss, culinary art mouthfeel poor, at the same time
Also easily there is spilling situation.In order to solve the problems, such as this, control module 20 by by above-mentioned temperature gap with close lid threshold value
Compare, whether judgement draws electric cooker in pass lid state.In the case where closing lid state, interior pot heating is very fast, reduces heating unit 30
Heating firepower, that is, reduce the heating firepower of electric cooker, electric cooker is realized the function that small fire is stewed slowly, electric cooker realizes heating fire
The adaptive adjustment of power, maintains the nutritional ingredient of cooked food, improves the culinary art mouthfeel of cooked food, can also be big
It is big to avoid due to closing overflow problem caused by high flame is cooked congee under lid state.
In order to ensure the response sensitivity during adjustment heating firepower of heating unit 30, above-mentioned pass is uncapped the control model of threshold value
Be trapped among 5 DEG C~20 DEG C, by set it is rational close lid threshold value and recording unit 21 records the time interval of detection temperature, can be with
After carrying out closing pot lid action, the heating unit 30 of electric cooker can be responded enzyme rapidly and sensitively the electric cooker made, be reduced original
The heating firepower that heating unit 30 is lifted for pot temperature in supplement, makes electric cooker that the adaptive work(of heating firepower be better achieved
