Add water in towards the cooker liner.
The actual amplitudes to be prestored in the controller 20 are the value that user pre-enters, and the actual amplitudes are food
Actual value, for example, in a concrete application, user adds 1 glass of meter Jin Hang in the cooker liner and cooked, then in the electric cooker
Input unit, as 1 glass of rice is inputted or selected on control panel, the controller 20 stores the numerical value.In another concrete application,
User adds 1 jin of chop in the cooker liner and stewed, then in the input unit of the electric cooker, as inputted on control panel
Or 1 jin of chop of selection, the controller 20 store the numerical value.
The controller 20 judges the more of water in the cooker liner according to the detection value and the actual amplitudes that prestore
It is few to be specifically, the controller 20 according to the difference or ratio of both the detection value and the actual amplitudes to prestore come
The number of water in the cooker liner judged.
In the embodiment of the present invention, the priming apparatus 30 includes water tank, water pump, water pipe and adds head, and the water tank is set
In the cooker body of the electric cooker, described plus head is arranged on the pot lid bottom surface of the electric cooker, the water tank and described plus water
Connected between head by the water pipe, the water pump is arranged on the water pipe, and is electrically connected with the controller 20.When described
When water is less than normal water in cooker liner, the controller 20 controls the water pump to open, with towards in the cooker liner plus water.When
So, the water tank can also be outer tank, i.e., is provided separately with the cooker body.
In the embodiment of the present invention, the food refers to rice or chop etc., without the water added including user.
It is understood that the numerical magnitude can be gravimetric value or bulking value.
In the present invention, electric cooker during work can automatic decision user amount of water whether the reality with the food of selection
Border value is consistent, when amount of water is less than water needed for actual amplitudes, the electric cooker control automatic watering of priming apparatus 30, to ensure
Food mouthfeel.
In one embodiment, the detection means 10 includes：
Temperature sensing unit 11, electrically connected with the controller 20, for detecting the temperature in the electric cooker；
Timing unit 12, electrically connected with the controller 20, for obtaining the temperature in the electric cooker from the first temperature
It is worth the actual heat time needed for second temperature value；
First memory cell 13, electrically connected with the controller 20, for storing heat time-quantity of food data control
Table；The heat time-quantity of food data table of comparisons to characterize the temperature in the electric cooker from first temperature value to
Theoretical heat time needed for the second temperature value and the corresponding relation between the theoretical value of food；And
First comparing unit 14, electrically connected with the controller 20, for compare the actual heat time and it is described plus
M- quantity of food data table of comparisons when hot, to obtain the detection value.
In the embodiment, temperature sensing unit 11 is arranged in electric cooker, is preferably provided in the inner cap of the electric cooker,
To detect the temperature of food vapors in the electric cooker.Due to cooker liner described in the inner cap face, food and coolant-temperature gage rise
Caused steam directly rises to inner cap, thus temperature sensing unit 11 be arranged in cover, the detection to temperature has fast
The sensitive effect of speed.
First temperature value can be initial temperature value, i.e. house temperature；Or first temperature value be 40 DEG C~50 DEG C.Second
Temperature value is the temperature value after heating a period of time, can be specifically 80 DEG C~90 DEG C.
Timing unit 12 obtains the actual heat time needed for the first temperature value to second temperature value, when quantity of food is identical
When, the actual heat time can change according to the number of user's amount of water, therefore by obtaining the actual heat time
It may determine that whether user adds and lacked water.For example, when the theoretical value of food is N, in theory, when the food for heating the N values
During thing, the theoretical heat time needed for temperature from first temperature value to the second temperature value in the electric cooker is T,
The timing unit 12 obtains an actual heat time, by compare the actual heat time fall the theoretical heat time which
In the range of, so as to the corresponding detection value for drawing food.
Illustrated below by taking a specific embodiment as an example：
In the embodiment, the value is bulking value.The bulking value is preferably cup amount, below by taking the amount of 1-8 cups as an example
Illustrate.The present invention is not defined to the size of this glass amount.Certainly, in other embodiments, the bulking value can also
Be in units of liter or milliliter, or, the value is gravimetric value.
As shown in Table 1, table one is heat time-quantity of food data table of comparisons：
| Theoretical heat time T (s) | Theoretical value N (cup) |
| 0 ＜ T≤t | 1 |
| T ＜ T≤(t+60) | 2 |
| (t+60) ＜ T≤(t+120) | 3 |
| (t+120) ＜ T≤(t+180) | 4 |
| (t+180) ＜ T≤(t+240) | 5 |
| (t+240) ＜ T≤(t+300) | 6 |
| (t+300) ＜ T≤(t+360) | 7 |
| T ＞ (t+360) | 8 |
In the table of comparisons, it is assumed that when boiling N cup rice, required for the temperature from the first temperature value to second temperature value in electric cooker
The theoretical heat time be T, as N=1,0 ＜ T≤t, wherein, t is electric cooker when boiling 1 glass of rice, and the temperature in electric cooker is from the
The most long or optimal theoretical heat time of one required for one temperature value to second temperature value, usually 60~80s, the t values
It can be had differences because the model performance of electric cooker is different, depending on the species of electric cooker.Accordingly, as N=2, t
＜ T≤(t+60)；As N=3, (t+60) ＜ T≤(t+120)；By that analogy, as N=8, T ＞ (t+360).
Assuming that the actual heat time that timing unit 12 obtains is t ＇, when the first comparing unit 14 compares the actual heating
Between and the heat time-quantity of food data table of comparisons, judge t ＇ fall T which in the range of, for example, when t ＇ fall in (t+
120) when between~(t+180), first comparing unit 14 show that the detection value is 4, that is, obtains the detection value
For 4 glasss of rice.
In the embodiment of the present invention, the controller 20 can judge the more of water in the cooker liner in several ways
It is few, for example, in one embodiment, the controller 20 can be sentenced by the actual amplitudes with the ratio for detecting value
Break the cooker liner in water number.In another embodiment, the controller 20 also includes judging unit 21, described to judge list
Member 21 is used to whether be more than 0 according to the actual amplitudes and the difference of the detection value, to judge that water is in the cooker liner
It is no few；
If so, the judging unit 21 judges that water is few；
If it is not, the controller 20 controls the electric cooker normal work.
In the embodiment, because the number of user's amount of water can directly influence the actual heat time, therefore when user adds
Water and actual rice amount and when mismatching, the detection value obtained according to the actual heat time is not one true
Real value, the detection value and real rice amount, i.e., can have deviation between actual amplitudes.For example, user needs to boil 3 glasss of rice
When, 3 glasss of rice are pre-entered, actual amplitudes described in the memory storage of controller 20 are equal to the data of 3 glasss of rice.Assuming that the detection dress
The detection value for putting 10 acquisitions is 2 glasss of rice, when being necessarily less than the theoretical heating of 3 glasss of rice due to the theoretical heat time of 2 glasss of rice
Between, namely the actual heat time that the timing unit 12 obtains be less than the theoretical heat time, but rice amount is identical,
For 3 glasss of rice, therefore can only be that water is very few the reason for cause the actual heat time to be less than the theoretical heat time, it is therefore, described to sentence
Disconnected unit 21 is by judging whether the actual amplitudes and the difference of the detection value are more than 0, to judge water in the cooker liner
Amount number.
In the embodiment, further, the electric cooker also includes the suggestion device 40 electrically connected with controller 20, if institute
Difference is stated more than 0, the judging unit 21 is additionally operable to judge whether the difference is less than or equal to preset vol value；
If so, the controller 20 controls the priming apparatus 30 towards in the cooker liner plus water；
If it is not, the controller 20 controls the suggestion device 40 to export cue.
In the present embodiment, when the difference is more than preset vol value, i.e., when described difference is excessive, the controller 20 is thought
Get the wrong sow by the ear, without adding water, but control the suggestion device 40 to export cue, with remind user restart electric cooker or
Check electric cooker whether operation irregularity.Preferably, the preset vol value is 3, and its unit is cup amount.
Difference is presented according to the type of suggestion device 40 in the cue, for example, in one embodiment, the prompting
Device 40 is the display being arranged on the electric cooker, then the cue is the text gone out shown by the display
The figures such as word, image.In another embodiment, the suggestion device 40 is the audio alert dress being arranged on the electric cooker
Put, then the cue is voice caused by the phonetic alarm device.
In the embodiment, when the difference n, which is more than 0, is less than or equal to 3, the controller 20 controls water pump to open.It is false
If pump capacity is the 1g/ seconds, water pump opens the t1 seconds, and (t1 and n corresponding relation is：During n=1, when t1=120, n=2, t1=
When 240, n=3, t1=360.) after adding water to terminate water pump closing, electric cooker is cooked according to normal program of cooking, directly
To end.In other embodiments, t1 can also be other values.
Further, the controller 20 is additionally operable to, when the difference is less than or equal to 0, control the electric cooker normal
Work.In the embodiment, when the difference is less than 0, illustrate that user's amount of water is more, then controller 20, which does not export, adds water signal
To priming apparatus 30.When the difference is equal to 0, illustrate that user's amount of water just matches with real rice amount.
It is further, real one to ensure that amount of water is moderate when the controller 20 controls the priming apparatus 30 plus water
Apply in example, the controller 20 also includes：
Second memory cell 22, the food of corresponding relation between the theoretical value and theoretical water of food is characterized for storing
Amount-water data the table of comparisons；
Second comparing unit 23, for comparing the actual amplitudes and the quantity of food-water data table of comparisons, to obtain
Actual amount of water corresponding with the actual amplitudes；Second comparing unit 23 is additionally operable to compare the detection value and the food
Object amount-water data the table of comparisons, detect that value is corresponding detects water with described to obtain；
Arithmetic element 24, for calculating the actual amount of water with the difference of the detection water to obtain amount of water.
As shown in Table 2, table two is quantity of food-water data table of comparisons：
In the table two, when theoretical rice amount, i.e., during theoretical value N ＇=1, required theoretical water w=120g；Theoretical amount
During value N ＇=2, required theoretical water w=240g ... is as theoretical value N ＇=8, required theoretical water w=
960g.Namely often increase by 1 glass of rice, to the water in requisition for increase 120g.Certainly, in other embodiments, water corresponding to 1 glass of rice
Amount can also be other numerical value, be determined with specific reference to the type of individual subscriber hobby or rice.
Specifically, if it is described detection value be 5, and user input actual amplitudes be 7 when, 5 glasss of rice correspond to 600g water, 7
Cup rice correspond to 840g water, illustrate that user's amount of water is very few, and the control water pump unlatching of controller 20, priming apparatus 30 is towards in the cooker liner
Add water, amount of water is 840g and 600g difference.
The present invention also proposes that a kind of electric cooker compensates the method for water automatically, as shown in Fig. 2 comprising the following steps：
S10：Detection means detects the numerical magnitude of food in the cooker liner of the electric cooker, obtains the detection value of food；
S20：Controller judges whether water is few in the cooker liner according to the detection value and the actual amplitudes to prestore；
S30：If so, the controller controls priming apparatus towards in the cooker liner plus water；
S40：If it is not, the controller controls the electric cooker normal work.
Wherein, as shown in figure 3, step S10 specifically includes following steps：
S11：The reality that timing unit obtains in the electric cooker needed for temperature from the first temperature value to second temperature value adds
The hot time；
S12：First comparing unit compares the actual heat time and the heat time to prestore-quantity of food data control
Table, to obtain the detection value；
The heat time-quantity of food data table of comparisons is characterizing the temperature in the electric cooker from first temperature
The corresponding relation being worth between the theoretical heat time needed for the second temperature value and the theoretical value of food.
In step S11, the temperature in the timing unit acquisition electric cooker is from the first temperature value to second temperature
The actual heat time needed for value is, the timing unit obtains the temperature of food vapors in the electric cooker from the first temperature value
To the actual heat time needed for second temperature value.Due to cooker liner described in the inner cap face, food and coolant-temperature gage produce when raising
Raw hot gas directly rises to inner cap so that inner cap temperature raises, therefore the logical temperature for obtaining inner cap has the effect of rapid sensitive
Fruit.
First temperature value can be initial temperature value, i.e. house temperature；Or first temperature value be 40 DEG C~50 DEG C.Second
Temperature value is the temperature value after heating a period of time, can be specifically 80 DEG C~90 DEG C.
Timing unit obtains the actual heat time needed for the first temperature value to second temperature value, when quantity of food is identical,
The actual heat time can change according to the number of user's amount of water, therefore can be with by obtaining the actual heat time
Judge whether user adds and lacked water.For example, when the theoretical value of food is N, in theory, when heating the food of the N values,
The theoretical heat time needed for temperature from first temperature value to the second temperature value in the electric cooker is T, described
Timing unit obtains an actual heat time, by comparing the actual heat time falls which scope in the theoretical heat time
It is interior, so as to the corresponding detection value for drawing food.
Illustrated below by taking a specific embodiment as an example：
In the embodiment, the value is bulking value.The bulking value is cup amount, below using the amount of 1-8 cups as
Example illustrates.The present invention is not defined to the size of this glass amount.Certainly, in other embodiments, the bulking value also may be used
By be in units of liter or milliliter, or, the value is gravimetric value.
As shown in above-mentioned table one, table one is heat time-quantity of food data table of comparisons.In the table of comparisons, it is assumed that boil N cup rice
When, the theoretical heat time required for temperature from the first temperature value to second temperature value in electric cooker is T, as N=1,0 ＜
T≤t, wherein, when t is that electric cooker boils 1 glass of rice, one required for temperature from the first temperature value to second temperature value in electric cooker
The individual most long or optimal theoretical heat time, usually 60~80s, the t values can exist because the model performance of electric cooker is different
Difference, depending on the species of electric cooker.Accordingly, as N=2, t ＜ T≤(t+60)；As N=3, (t+60) ＜ T
≤(t+120)；By that analogy, as N=8, T ＞ (t+360).
Assuming that the actual heat time that timing unit obtains be t ＇, the first comparing unit compare the actual heat time with
The heat time-quantity of food data the table of comparisons, judge t ＇ fall T which in the range of, for example, when t ＇ fall (t+120)~
(t+180) when between, first comparing unit show that the detection value is 4, that is, it is 4 glasss of rice to obtain the detection value.
In one embodiment, as shown in figure 4, step S20 specifically includes following steps：
S21：The controller obtains the actual amplitudes and the difference of the detection value,
S22：Judging unit judges whether the difference is more than 0；
If so, the judging unit judges that water is few；
S28：If it is not, the controller controls the electric cooker normal work.
In the embodiment, because the number of user's amount of water can directly influence the actual heat time, therefore when user adds
Water and actual rice amount and when mismatching, the detection value obtained according to the actual heat time is not one true
Real value, the detection value and real rice amount, i.e., can have deviation between actual amplitudes.For example, user needs to boil 3 glasss of rice
When, 3 glasss of rice are pre-entered, actual amplitudes described in the controller memory storage are equal to the data of 3 glasss of rice.Assuming that the detection means
The detection value of acquisition is 2 glasss of rice, because the theoretical heat time of 2 glasss of rice is necessarily less than the theoretical heat time of 3 glasss of rice,
The actual heat time that i.e. described timing unit obtains is less than the theoretical heat time, but rice amount is identical, is 3 glasss
Rice, therefore can only be that water is very few the reason for cause the actual heat time to be less than the theoretical heat time, therefore, the judging unit
By judging whether the actual amplitudes and the difference of the detection value are more than 0, come judge water in the cooker liner number.
In above-mentioned steps, the judging unit also includes after judging water less：
S23：The judging unit judges whether the difference is less than or equal to preset vol value；
S27：If so, the controller controls the priming apparatus towards in the cooker liner plus water；
S29：If it is not, the controller control suggestion device output cue.
In the present embodiment, when the difference is more than the preset vol value, i.e., when described difference is excessive, the controller is recognized
To get the wrong sow by the ear, without adding water, but control the suggestion device output cue, with remind user restart electric cooker or
Check electric cooker whether operation irregularity.Preferably, the preset vol value is 3, and its unit is cup amount.
Difference is presented according to the type of suggestion device in the cue, for example, in one embodiment, the prompting dress
The display being arranged on the electric cooker is set to, then the cue is word, the figure gone out shown by the display
The figures such as picture.In another embodiment, the suggestion device 40 is the phonetic alarm device being arranged on the electric cooker, then institute
It is voice caused by the phonetic alarm device to state cue.
In the embodiment, when the difference n, which is more than 0, is less than or equal to 3, the controller control water pump is opened.Assuming that
Pump capacity is the 1g/ seconds, and water pump opens the t1 seconds, and (t1 and n corresponding relation is：During n=1, when t1=120, n=2, t1=
When 240, n=3, t1=360.After adding water to terminate water pump closing, electric cooker is cooked according to normal program of cooking, until
Terminate.
It is further comprising the steps of before step S27：
S24：Second comparing unit compares actual amplitudes and the quantity of food-water data table of comparisons to prestore, with acquisition and institute
State actual amount of water corresponding to actual amplitudes；
