Please arrange in pairs or groups and consult Fig. 2, Fig. 3, the sketch map of the stove and accessory that it prevents for the present invention to be dryouied by the thing that boils.This stove and accessory 1 comprises a body of heater 11, a check weighing element 12, a control interface 16, and is arranged at this body of heater 11 inner a monitoring element 13, an arithmetic element 14, and a thermal source control module 15.
Below specify the present invention; At first; The user can control interface 16 via this and open this stove and accessory 1; And see control signal CS via this control interface 16 of adjustment off and make this body of heater 11 produce the thermal source of a heating to thermal source control module 15, in order to heat the quilt thing that boiled, this control interface 16 also is available for users to set the time length of desiring to boil; Moreover; This stove and accessory also is provided with pot supporter 17, bottom bracket 18, and this pot supporter 17 is in order to putting this quilt thing that boils, these bottom bracket 18 usefulness so that the bottom of this body of heater 11 with put these body of heater 11 parts and produce a gap; To increase the radiating efficiency of this body of heater 11; This check weighing element 12 can be arranged at this pot supporter 17 or be this bottom bracket 18, with this quilt of sensing weight of thing that boils, and produces the weight signal WS of the thing that boiled thereupon.
Please arrange in pairs or groups and consult Fig. 4, Fig. 5, it is boiled when the boiling thing weight decline curve sketch map of thing of user cooking.If the user continues to start to arrange this quilt thing that boils in that this body of heater 11 is other; Represent that then this quilt thing that boils is under user's the state of a control; Then the anti-security mechanism of dryouting of the present invention does not need to start; In order to avoid influence the control of user to cooking food, whether the purpose that this monitoring element 13 is set promptly is to monitor the user and cooks, and 13 fens level signals of this monitoring element connect this check weighing element 12 and should control interface 16; If it is big or small with the firepower of the thermal source adjusting this body of heater 11 and produce that the user operates this control interface 16; Then this monitoring element 13 can receive a control signal CS who is produced from this control interface 16, and then monitoring element 13 can judge that the user arranges, and does not start anti-security mechanism of dryouting; Likewise; Monitoring element 13 also can receive the weight signal WS that is produced from this check weighing element 12; Increase or reduce or stir by the thing that boils if the user is simple, for example, the user is in the process of the cooking; Add soup juice or take out the food materials that boiled; The feasible quilt thing weight that boils increases suddenly in short a few minutes or reduces 20%, or the user is simple stirring or stir by the thing that boils, and the weight signal of the thing that then boiled just can rapid change, increase or minimizing in the interval Ts of a monitoring time of short period length; The weight that takes place in the interval Ts of monitoring time shown in Fig. 4-5 sharply changes, just this monitoring element 13 can judge that the user is controlling cooking action and need not start anti-security mechanism of dryouting.
Otherwise; If this weight signal of this monitoring element monitoring changes when dropping to a preset slope sustainedly and stably (
); Represent promptly that this user possibly forget and cook; And need startup to prevent the security mechanism of dryouting; Wherein the time length of the interval Ts of this monitoring time is looked the design of this monitoring element 13, for example also can be, within one minute; The thing weight that boiled increases or reduces 10%, judges that just the user cooks.
Thermal source (for example the firepower of this thermal source being turned down) that the specific practice of the security mechanism that the present invention prevents to be dryouied by the thing that boils produces for this body of heater 11 of adjustment or the thermal source of directly closing this stove and accessory, the firepower of the thermal source that this body of heater 11 of above-mentioned adjustment produces or the time point of directly closing the thermal source of this stove and accessory then depend on this arithmetic element 14.
Please arrange in pairs or groups and consult Fig. 3 and Fig. 6; It is the sketch map of a preferred embodiment of arithmetic element calculated weight variable quantity ratio of the present invention; This arithmetic element 14 is connected with these monitoring element 13 signals, is received from the weight signal WS that monitoring element 13 is transmitted, and this weight signal WS changed with the time of boiling; Comprising there being a weight change to calculate initial value W0, that is monitoring element 13 judge time point T0 when this moment, the user cooked as yet to the weight of the thing that should be boiled.
Moreover; This arithmetic element 14 will be according to when cooking; Be heated to the phenomenon that the weight of the thing that boiled behind the boiling point of liquid can be quickened to descend by the thing that boils, in regular turn in the interval T1 of a plurality of continuous next-door neighbours' different time, T2, T3, T4, T5, T6, calculate a plurality of weight change amount Δ W1, Δ W2, Δ W3, Δ W4, Δ W5, Δ W6 respectively the thing weight decline of being boiled in should a plurality of time intervals; And select a weight change amount as the pivot weight variable quantity, Δ W2 for example; Wherein, Select arbitrary weight change amount as the pivot weight variable quantity; It is the setting of looking in the arithmetic element; If it is less to avoid heating the initial stage weight change; The weight change amount that also can select to heat the stage casing is as the pivot weight variable quantity; Afterwards in regular turn the ratio
of a plurality of weight change amount Δ W3, Δ W4, Δ W5, Δ W6 and the weight change amount Δ W2 that produce of calculated for subsequent in case this ratio greater than a default value; For example; On behalf of this weight decrease speed, ratio
also accelerate to a degree greater than this default value.With actual conditions; The temperature of thing of promptly being boiled has arrived the boiling point of its liquid; Continue to heat the danger that promptly can be dryouied by the thing that boils, then this arithmetic element 14 will produce thermal source adjustment signal, and this thermal source adjustment signal is received by this thermal source control module 15; And according to this thermal source adjustment signal adjustment and control the firepower of the thermal source that this body of heater 11 produces, thing is dryouied to prevent to be boiled.
When a plurality of time interval of aforementioned calculation produces corresponding a plurality of weight change amount; If monitoring element 13 is judged the user and is just cooked on the stove and accessory side; That is the weight of the thing that boiled is rapid increase and decrease in the monitoring time interval, or detecting has control signal CS; Then must judge when the user does not cook by element 13 to be monitored; Produce a weight change in addition and calculate initial value W0, recomputate again afterwards in follow-up a plurality of time interval and produce the time point of corresponding a plurality of weight change amount, avoid dryouting by the thing that boils with decision adjustment thermal source.
See also Fig. 7 again, it is the sketch map of a preferred embodiment of calculated weight variable quantity of the present invention, and this weight change amount can be a weight signal difference that is produced between two time points in this time interval.As shown in the figure; This weight change amount Δ W1 is two time point T1a in this time interval T1, the weight signal difference (W1a-W1c) of T1c; Look the design of this arithmetic element, this weight change amount Δ W1 also can be the summation (W1a-W1b)+(W1b-W1c) of difference between the weight signal W1a, W1b, W1c of three time point T1a in this time interval T1, T1b, T1c.
In addition; This weight change amount Δ W1 also can be in this time interval T1, and a weight signal difference (W1a-W1c) that is produced between at least two time point T1c, T1a and weight change are calculated percent value
between initial value W0 this is all looked the design of arithmetic element; Certainly, this weight change amount also can be the summation of difference between the pairing a plurality of weight signals of a plurality of time points in the time interval.
What need special instruction is that when the anti-stove and accessory that dryouies of the present invention was implemented, this stove and accessory can be gas furnace, electrothermal furnace, electromagnetic oven or micro-wave oven, but is not limited to wherein a kind of.This check weighing element 12 can be mechanical type weighing scale or electronic type weighing scale any, and this monitoring element 13 can be integrated with this arithmetic element 14 and is arranged in the processing unit.
The present invention also provides another preferred embodiment, sees also Fig. 8, and it is the sketch map of another preferred embodiment of arithmetic element calculated weight variable quantity ratio of the present invention.For reducing the operand of this arithmetic element 14; This arithmetic element 14 receives and passes behind the weight signal of this monitoring means 13; In regular turn in the interval T7 of a plurality of different times, T8, T9, T10; Calculate a plurality of weight change amount Δ W7, Δ W8, Δ W9, the Δ W10 that are descended by the thing weight that boiled in should a plurality of time intervals respectively; Wherein this a plurality of different times interval is discontinuous time interval, that is has a time difference Ti between this time interval and the time interval, and this time difference Ti can adjust according to the firepower size of thermal source.For instance; When if the firepower of thermal source is big; The thing water evaporates that then boiled is very fast; Then need the short time difference Ti of time span this moment; Otherwise; The time span of poor Ti then gets time extension; Then select a weight change amount as the pivot weight variable quantity; Δ W7 for example; Again in regular turn the ratio
of a plurality of weight change amount Δ W8, Δ W9, Δ W10 and the weight change amount Δ W7 that produce of calculated for subsequent in case this ratio greater than a default value; For example ratio
is greater than this default value; Also represent this weight decrease speed to accelerate to a degree, by the thing that boils the possibility of being dryouied is arranged, this arithmetic element 14 promptly produces thermal source adjustment signal; This thermal source control module 15 is again according to this thermal source adjustment signal adjustment and control the heating thermal source that this body of heater 11 produces, and thing is dryouied to prevent to be boiled.
Thus; When this a plurality of different times interval is discontinuous time interval; Represent to have a time difference Ti between each time interval, then because of the weight change amount that in time interval, produces reduces, so the effect of the operand that reduces this arithmetic element 14 is not only arranged; And still can judge equally by the thing that boils has the possible time point that is dryouied, and thing is dryouied to avoid being boiled.
In addition, for solving the thing that boiled in being heated the more unconspicuous problem of initial stage weight decline, the present invention also provides the 3rd preferred embodiment; See also Fig. 9, it is the sketch map of the 3rd preferred embodiment of arithmetic element calculated weight variable quantity ratio of the present invention.Arithmetic element 14 receives and passes behind the weight signal of this monitoring means 13; In regular turn in the interval T11 of a plurality of different times, T12, T13, calculate a plurality of weight change amount Δ W11, Δ W12, the Δ W13 that is descended by the thing weight that boiled in should a plurality of time intervals respectively; Wherein this time interval T11 and time interval T12, T13 are the time interval of different time length; Because of heating initial stage weight descends more not obvious; So calculate pairing weight change amount Δ W11 in the time interval T11 of a long period length; As the pivot weight variable quantity; Then in regular turn the ratio
of a plurality of weight change amount Δ W12, Δ W13 and the weight change amount Δ W11 that produce of calculated for subsequent in case this ratio greater than this default value; For example ratio
is greater than this default value; Then this arithmetic element 14 will produce thermal source adjustment signal; This thermal source control module 15 is again according to this thermal source adjustment signal adjustment and control the thermal source that this body of heater 11 produces, and thing is dryouied to prevent to be boiled.
More than the conclusion, the present invention also provides a kind of anti-method of dryouting that is applied to stove and accessory, sees also Figure 10, and it is applied to the anti-flow chart that dryouies method of stove and accessory for the present invention, and the step of this method is following:
A: start a stove and accessory, a thermal source that produces with this stove and accessory heats the thing that boiled;
B: monitor the boil weight of thing of this quilt, and produce weight signal;
C: whether the monitoring user just cooks action on the stove and accessory side, if, then carry out step B, if not, then carry out step D; And
D: produce in order to adjust the thermal source adjustment signal of this thermal source, to reach and prevent to dryout function; Wherein, this step (D) is included in a plurality of time intervals, produces corresponding a plurality of weight signal variable quantity respectively, and produces this thermal source adjustment signal according to those weight signal variable quantities.
The detailed step of said method below will be described with two preferred application embodiment.
See also Figure 11, it is the anti-flow chart that dryouies the first preferred application embodiment of method of the present invention.At first, when the user cooks, will be placed in the heating location of stove and accessory by the thing that boils after; Carry out step S1, start this stove and accessory, this stove and accessory will produce a thermal source to the boil thing heating of this quilt; Carry out step S2 this moment, begin to monitor boiled thing weight and produce weight signal thereupon; Generally speaking, can be more and more longer owing to boiled thing with heat time heating time, weight can be more and more lighter; So this weight signal also can change with heat time heating time, if dryouied be heated to boiled thing if the user diverts one's attention to forget because of thing to be cooked this moment; Then can cause danger,, continue to monitor the user and whether cook so carry out step S3; For example say that the user is adjusting the firepower size of thermal source, or set the cooking time.
In addition; The user may be according to the degree of heat of the thing that boiled; Add other food materials, or the food materials that will boil take out and cause the thing weight that boiled to increase or reduce, or the user stirs or stirs the thing that boiled; The rapid variation of this weight signal of monitoring is caused in the capital, therefore can whether operate the control interface of this stove and accessory or monitor this weight signal whether in a monitoring time interval, produce rapid variation by this user of monitoring; Wherein, this monitoring time is interval for preset, for example: if the boil weight minimizing 20% of thing of this quilt in three minutes; Promptly be judged as the user and take out, or the boil weight of thing of this quilt increases by 20% in three minutes, promptly is judged as the user and is adding by the thing that boils by the thing that boils; If judge that the user cooks, then return and carry out step S2, if having, the judgement user do not cook; That is the user possibly divert one's attention or must not start on the stove and accessory side to prevent the mechanism of dryouting because of thing; At this moment, select the weight signal of a time point T0 to calculate initial value W0, use usefulness for the subsequent step computing as weight change; On behalf of this time point, the time point that this weight change calculating initial value W0 occurs also judge that user does not move in the control cooking, carries out step S4 afterwards.
Please arrange in pairs or groups and consult Figure 11 and Figure 12, it dryouies the sketch map that calculates a preferred embodiment of weight change amount ratio among the first preferred application embodiment of method for the present invention is anti-.In the interval T14 of a plurality of different times, T15, T16, T17, calculate and produce corresponding a plurality of weight signal variation delta W14, Δ W15, Δ W16, Δ W17, and select a weight change amount, for example Δ W14 in regular turn as the pivot weight variable quantity.Carry out step S5; The weight change amount ratio
of a plurality of weight change amount Δ W15, Δ W16, Δ W17 and the weight change amount Δ W14 of calculated for subsequent generation in regular turn also judges that in regular turn whether this weight change amount ratio
is greater than one first default value; If; When for example boiling time point T17c; The weight change amount ratio
that calculate this moment is greater than this first default value; Also represent this weight decrease speed to accelerate to a degree; With actual conditions; The temperature of thing of promptly being boiled has arrived the boiling point of its liquid; Then carry out step S7; Generation is heated to the thing of avoiding being boiled in order to the thermal source adjustment signal of adjusting this heating thermal source dryouies; If not; For example; When boiling time point T15c; The weight change amount ratio
that calculate this moment is less than or equal to this first default value; The boiled weight decrease speed of thing of representative is still kept stablely, then carries out this step S6.
Need specify at this; Just cook if in carrying out step S5, still monitor the user; Must wait then to judge that the user does not cook after the action again; Produce a new weight change in addition and calculate initial value W0, recomputate again afterwards in follow-up a plurality of time interval and produce the time point of corresponding a plurality of weight change amount, avoid dryouting by the thing that boils with decision adjustment thermal source; Proceed step S6 afterwards again, its purpose be to avoid merely with weight change amount ratio can't discover dryout situation below special cooking situation take place:
1. boiled thing for fluidized state, that is be in by the thing that boils when starting stove and accessory or near the state of boiling;
2. this quilt thing that boils is heated to when boiling, and also in the firepower size of adjustment thermal source, for example, when being boiled the thing boiling, the user also is adjusted into little fire with the firepower of thermal source to the user simultaneously, boils and continue to stew the cooking method of boiling slowly with little fire; If above-mentioned situation takes place, the weight decrease speed that then obtains this quilt being boiled the thing monitoring possibly not have significant difference.
Therefore; Step S6 is that summation and this weight change of calculating these a plurality of weight change amount Δ W14, Δ W15, Δ W16, Δ W17 are calculated the percent value between initial value W0, and whether judges this percent value greater than one second default value, that is judges whether the gross weight that is evaporated by the thing that boils is excessive; If not; For example say to be heated to time point T15c, boil gross weight (Δ W14+ Δ W15) that thing evaporates and weight change of this quilt calculated a percent value between initial value W0 not greater than second default value, that is this quilt boils gross weight that thing evaporates above a safety margin when being heated to time point T15c; Still there is not the danger of dryouting the thing that boiled; Then return and carry out step S2, if for example be heated to time point T15c; Boil gross weight (Δ W14+ Δ W15) that thing evaporates and weight change of this quilt calculated a percent value between initial value W0 greater than second default value; Have and dryout the dangerous immediately of the thing that boiled, then carry out step S7, produce and adjust signal in order to a thermal source of adjusting this heating thermal source and continued to be heated to the thing of avoiding being boiled and dryout.
This thermal source adjustment signal is in order to start a thermal source set-up procedure, and this thermal source set-up procedure comprises following three embodiments, and the thing of all avoiding being boiled is heated to and dryouies, and below introduces respectively.
See also Figure 13, it is the flow chart of first kind of embodiment of thermal source set-up procedure, may further comprise the steps:
S71: judge whether the user utilizes the thermal source size and a limiting time length of one second section firepower of a control interface setting of this stove and accessory, if, then carry out step S72, if not, then advance shape step S74;
S72: the thermal source size of second section firepower setting according to this user is seen a thermal source control signal off, to adjust the firepower size of the thermal source that this stove and accessory produces;
S73: beginning this limiting time length reciprocal; And
S74: the thermal source of closing this stove and accessory.
Because may imagining earlier to be easy to act as by the thing that boils in advance, the user on stove and accessory, is in cooking status and the corresponding method of user when forgetting; For instance; The user can utilize the control interface that the situation of this thermal source adjustment is set in advance, when this quilt boils after thing reaches boiling point, this thermal source is adjusted into alternative second section firepower (for example being set at little fire); And continue to boil 5 minutes with this second section firepower again; Close the thermal source of stove and accessory again, except that the thing of avoiding being boiled is dryouied, also can reach and make the well-done effect of the thing that boiled; If the user does not set the thermal source size and the limiting time of second section firepower, when this quilt boils after thing reaches boiling point, also can directly close the thermal source of stove and accessory, thing is dryouied because of continuing to heat quilt to avoid being boiled.
In other embodiments, see also Figure 14, the user also can individual setting one limiting time length, or the thermal source of one second section firepower of individual setting size, and is shown in figure 15.In Figure 14, step S75 at first: judge whether the user sets a limiting time, if then carry out step S76: beginning this limiting time reciprocal, if not, then carry out the thermal source that step S77 closes stove and accessory, thing is dryouied because of continuing the heating quilt to avoid being boiled.In addition; Please refer to Figure 15; Step S78 at first: judge earlier whether the user sets the thermal source size of second section alternative firepower, if then carry out step S79: it is big or small with adjustment thermal source firepower that second section firepower setting according to this user seen a thermal source control signal off; If not, then carry out the thermal source that step S710 closes stove and accessory.In this embodiment; If the user has the thermal source size of setting the second section firepower that substitutes; The thing that can continue to be boiled remains in uniform temperature and unlikely cooling, also can make the state that is broken away from boiling by the thing that boils, and the thing of avoiding being boiled is dryouied; Thus, can reach the demand that anti-effect of dryouting also can satisfy user's different cooking methods.
Above-mentioned three kinds of embodiments are all the practical application of thermal source set-up procedure of the present invention, and all can reach the thing that prevents to be boiled because of continuing the purpose that heating is dryouied.
Wherein, Please consult Figure 16 again, it dryouies the sketch map that calculates another preferred embodiment of weight change amount ratio among the first preferred application embodiment of method for the present invention is anti-, for solving the thing that boiled in being heated the initial stage weight more unconspicuous problem that descends; This a plurality of different times interval can be the time zone of different time length; For example, calculate pairing weight change amount Δ W14 in the time interval T14 of a long period length, and get this weight change amount Δ W14 as the pivot weight variable quantity; The time interval length that cause is got is longer, so weight change is comparatively obvious.
In addition, see also Figure 17, it dryouies the sketch map that calculates the 3rd preferred embodiment of weight change amount ratio among the first preferred application embodiment of method for the present invention is anti-.The interval T14 of these a plurality of different times, T15, T16, T17 are a plurality of time intervals that are close to continuously among this first preferred application embodiment, also can be a plurality of time intervals of discontinuous next-door neighbour.Shown in figure 17; Has a time difference Ti between this each time interval T14 ', T15 ', T16 '; And this time interval T14 ', T15 ', T16 ' produce corresponding weight change amount Δ W14 ', Δ W15 ', Δ W16 '; When therefore carrying out step S5, a plurality of weight change amount Δ W15 ' of calculated for subsequent generation in regular turn, Δ W16 ' judge that with the weight change amount ratio
of weight change amount Δ W14 ' whether this weight change amount ratio
is greater than first default value.Originally needing calculating four time interval T14, T15, T16, T17 just can judge this weight change amount ratio
among the first preferred application embodiment greater than the 3rd default value; It is existing if these a plurality of time intervals are discontinuous next-door neighbour's a plurality of time interval T14 ', T15 ', T16 '; Then judge to weight change amount ratio
promptly can be greater than the 3rd default value; Just can reduce the calculating of a weight change amount ratio thus, also can reduce the amount of calculation of hardware.
In addition; See also Figure 18; It dryouies the sketch map that calculates a preferred embodiment of weight change amount among the first preferred application embodiment of method for the present invention is anti-, this weight change amount can be a weight signal difference that is produced between two time points in this time interval.As shown in the figure; This weight change amount Δ W15 is two time point T15c in this time interval T15, the weight signal difference (W15a-W15c) of T15a, and this weight change amount Δ W15 also can be the summation (W15a-W15b)+(W15b-W15c) of difference between the weight signal W15a, W15b, W15c of three time point T15a in this time interval T15, T15b, T15c.In addition; This weight change amount also can be in this time interval T15, and a weight signal difference (W15a-W15c) that is produced between at least two time point T15c, T15a and a weight change are calculated the percent value
between initial value W0
Next the present invention second preferred application embodiment is described.See also Figure 19, it is the anti-flow chart that dryouies the second preferred application embodiment of method of the present invention.When beginning to boil, step S1 among step and the first preferred application embodiment, S2 are identical, so do not give unnecessary details.After step S2, carry out step S3, whether the monitoring user cooks; For example say that the user is operating the control panel adjustment thermal source size of stove and accessory, or set the cooking time, in addition; The user may add other food materials according to the degree of heat of the thing that boiled, or the food materials that will boil take out; Or stirring or stirring food materials, and cause the monitoring resulting weight signal of thing that boiled to increase or reduce, therefore can whether operate the control interface of this stove and accessory or monitor this weight signal whether in a monitoring time interval, produce rapid variation by this user of monitoring; Wherein, this monitoring time is interval for preset, if; Judge that promptly the user is cooking action, then carry out step S2, if judge that the user does not have the action of cooking; That is the user possibly divert one's attention or not by stove and accessory because of thing, at this moment, selects the weight signal W0 of a time point T0 to calculate initial value as a weight change; Use usefulness, carry out step S8, please arrange in pairs or groups and consult Figure 20 for the subsequent step computing; It dryouies the sketch map that calculates a preferred embodiment of weight change amount ratio among the second preferred application embodiment of method for the present invention is anti-, in regular turn in the interval T18 of a plurality of different times, T19, T20, T21, calculate and produce corresponding a plurality of weight signal variation delta W18, Δ W19, Δ W20, Δ W21; And select a weight change amount as the pivot weight variable quantity, for example Δ W18 carries out step S9; The weight change amount ratio
of a plurality of weight change amount Δ W19, Δ W20, Δ W21 and the weight change amount Δ W18 of calculated for subsequent generation in regular turn judges that whether this weight change amount ratio
is greater than one the 3rd default value; If when for example boiling time point T21c, the weight change amount ratio
that calculate this moment is greater than the 3rd default value; Also represent this weight decrease speed to accelerate to a degree; With actual conditions, the thing that promptly boiled has arrived boiling point, then carries out this step S11; Generation is heated to the thing of avoiding being boiled in order to the thermal source adjustment signal of adjusting this heating thermal source dryouies; If not, for example, when boiling time point T19c; The weight change amount ratio
that calculate this moment is still less than the 3rd default value; It is stable also to represent the weight decrease speed of the thing that boiled still to keep, and then carries out this step S10, and the following situation that the purpose of carrying out step S10 is to avoid merely to discover the situation of dryouting with weight change amount ratio takes place:
1. boiled thing for fluidized state, that is be in by the thing that boils when starting stove and accessory or near the state of boiling;
2. this quilt thing that boils is heated to when boiling, and the user also adjusts the firepower size of thermal source simultaneously, and for example, when being boiled the thing boiling, the user also is adjusted into little fire with the firepower of thermal source simultaneously, continues to stew the cooking method of boiling slowly with little fire again and boils;
For example; When boiling time point T19c, this moment, step S10 was that a weight signal W19c and a weight change of calculating single time point T19c calculated the percent value between initial value W0, and judged that whether this percent value is less than one the 4th default value; That is judge whether the remaining gross weight of part that is evaporated by the thing deduction that boils is too small; If not, promptly represent the thing that boiled still can continue heating, then return and carry out step S2; If; Promptly represent to be in above-mentioned two kinds of situation and very possible by the thing that boils the situation of being dryouied by the thing that boils takes place, then carry out step S11, produce and adjust signal in order to a thermal source of adjusting this heating thermal source and be heated to the thing of avoiding being boiled and dryout.Wherein this thermal source adjustment signal is in order to starting a thermal source set-up procedure, and the embodiment of this thermal source set-up procedure is identical with thermal source set-up procedure among the first preferred application embodiment, sees also Figure 12,14 and 15, so repeat no more at this.
See also Figure 21; It dryouies the sketch map that calculates another preferred embodiment of weight change amount ratio among the second preferred application embodiment of method for the present invention is anti-; For solving the thing that boiled in being heated the more unconspicuous problem of initial stage weight decline; This a plurality of different times interval can be the time interval of different time length, for example, calculates pairing significantly weight change amount Δ W18 in the time interval T18 of a long period length.In addition, see also Figure 22, it dryouies the sketch map that calculates the 3rd preferred embodiment of weight change amount ratio among the second preferred application embodiment of method for the present invention is anti-.Among the second preferred application embodiment; The interval T18 of these a plurality of different times, T19, T20, T21; Be a plurality of time intervals that are close to continuously; Excessive for solving amount of calculation; The a plurality of time intervals that also can be discontinuous next-door neighbour are to reduce amount of calculation; Shown in figure 22; Has a time difference Ti between this each time interval T18 ', T19 ', T20 '; And this time interval T18 ', T19 ', the corresponding weight change amount Δ W18 ' of T20 ', Δ W19 ', Δ W20 '; When therefore carrying out step S9, a plurality of weight change amount Δ W19 ' of calculated for subsequent generation in regular turn, Δ W20 ' judge that with the weight change amount ratio
of weight change amount Δ W18 ' whether this weight change amount ratio
is greater than one the 3rd default value again.In the second preferred application embodiment, need to calculate four time interval T18, T19, T20, T21 and just can judge this weight change amount ratio
greater than the 3rd default value; If these a plurality of time intervals are discontinuous next-door neighbour's a plurality of time interval T18 ', T19 ', T20 '; Then judge to weight change amount ratio
promptly can be greater than the 3rd default value; Just can reduce the calculating of a weight change amount ratio thus, also reduce the burden that hardware calculates.
In addition; See also Figure 23; It dryouies the sketch map that calculates a preferred embodiment of weight change amount among the second preferred application embodiment of method for the present invention is anti-, this weight change amount can be a weight signal difference that is produced between two time points in this time interval.As shown in the figure; This weight change amount Δ W19 is two time point T19a in this time interval T19, the weight signal difference (W19a-W19c) of T19c, and this weight change amount Δ W19 also can be the summation (W19a-W19b)+(W19b-W19c) of difference between the weight signal W19a, W19b, W19c of three time point T19c in this time interval T19, T19b, T19a.In addition; This weight change amount Δ W19 also can be in this time interval T19, and a weight signal difference (W19a-W19c) that is produced between at least two time point T19a, T19c and a weight change are calculated the percent value
between initial value W0
In this special instruction; The first preferred application embodiment and the second preferred application embodiment provide two kinds of different modes to be in the situation that can't prevent to be dryouied by the thing that boils with weight decrease speed variable quantity merely to solve by the thing that boils, and all can avoid the possibility of being dryouied by the thing that boils.
Comprehensive the above, whether the present invention can see through the boiled variation and the monitoring user of thing weight decrease speed of monitoring really and cook, and reaches to prevent the predicament generation of being dryouied because of continuing heating by the thing that boiled.
