| Set cook temperature (KK) | Heater portion fiducial temperature (HK) | Inboard heater energising | Front side heater energising | Following heater energising |
| 250℃ | 400℃ | 100% (continuously) | 100% (continuously) | 100% (continuously) |
| 200℃ | 380℃ | 100% (continuously) | Energising in 25 seconds outage in 5 seconds | 100% (continuously) |
| 150℃ | 350℃ | 100% (continuously) | Energising in 20 seconds outage in 10 seconds | 100% (continuously) |
| 100℃ | 300℃ | 100% (continuously) | Energising in 15 seconds outage in 15 seconds | 100% (continuously) |
For example, when setting cook temperature KK was 250 ℃, the fiducial temperature HK of heater portion was decided to be 400 ℃, and the current on time of front side heater 21 is decided to be 100% (continuously).And for example, when setting cook temperature KK was 200 ℃, the fiducial temperature HK of heater portion was decided to be 380 ℃, and the current on time of front side heater 21 is decided to be " 25/30 ".In addition, the current on time of inboard heater 22 all is decided to be 100% (continuously).
After step P1, move to step P2, judge the height that is heated food according to the detection signal of optical sensor 13,14.That is, only provide, then be judged as " low ",, then be judged as " height " if provide from optical sensor 14 at least from optical sensor 13 if be heated the food inspection signal.When being judged as " height ", move to step P3, such current on time that changes front side heater 21 as shown in table 2.From table 2 and table 1 more as can be known, under the situation that is heated food " height ", current on time is changed into about 80% of " low " situation.By aftermentioned as can be known, the current on time of each heater 21,22,29 shown in table 1 and the table 2 is after front side temperature sensor 25 or inboard temperature sensor 26 reach the fiducial temperature HK of heater portion, and it is just effective later on perhaps to reach the cook temperature KK that cook temperature sensor 28 sets.

After step P3, move to step 4, in the time of 21 energisings of front side heater, also to inboard heater 22 energisings.Figure 11 represents when the cook temperature KK that sets is 150 ℃, the control situation of the variations in temperature of each one and each heater 21,22,29.Below, the situation when being 150 ℃ to setting cook temperature KK is described.In this case, the fiducial temperature HK of heater portion is decided to be 350 ℃.
Because the energising of front side heater 21 and inboard heater 22 gradually is heated in the cooking chamber 4.For example between 30 seconds (judge) beginning to be no more than the predetermined detection cycle from cooking at step P5, whether the cooking time that judgement is set by cooking time setting switch passes through (step P6), if process just to whole heater 21,22,29 outages (step P7), is returned main program; If do not pass through, judge then whether the detected temperatures (being called " front side temperature " among the diagram program figure) of front side temperature sensor 25 or the detected temperatures (being called " inboard temperature " among the diagram program figure) of inboard temperature sensor 26 have surpassed the fiducial temperature HK of heater portion (be 350 ℃ this moment) (step P8), do not surpass as crossing, judge then whether the detected temperatures of cook temperature sensor 28 has surpassed setting cook temperature KK (be 150 ℃ this moment) (step 9).At this step P9, surpassed setting cook temperature KK if be judged as the detected temperatures of cook temperature sensor 28, then, move to aftermentioned step P14 to whole heater 21,22,29 outages (step P10), if do not surpass, then return step P5.
When above-mentioned steps P5, step P6, step P8, step P9 are " N ", carry out the closed loop of these steps, promptly wait for 30 seconds time.After through 30 seconds (moment t1 of Figure 11), move on to step P11, judge whether the detected temperatures of inboard temperature sensor 26 surpasses the detected temperatures of front side temperature sensor 25, if surpass, then move to step P12, make inboard heater 22 outages and heater 29 energisings downwards, if do not surpass, then move to step P13, give inboard heater 22 energisings, and make down heating 29 outages.
Above-mentioned 30 seconds of every process, with regard to execution in step P1, step P12 or step P13, the temperature in the cooking chamber 4 gradually rises, and simultaneously, the temperature of front side heater 21 and inboard heater 22 parts also gradually rises.
When the detected temperatures of front side temperature sensor 25 or inboard temperature sensor 26 surpasses the fiducial temperature HK of heater portion (step P8 " Y ") or during when the detecting temperature and surpass setting cook temperature KK (step P9 " Y ") of cook temperature sensor 28, the control that execution in step P14 is later.At the moment of Figure 11 t2, represent that the detected temperatures of inboard temperature sensor 26 has surpassed the situation of the fiducial temperature HK of heater portion.
At step P14, judge whether the detected temperatures of front side temperature sensor 25 surpasses the fiducial temperature HK of heater portion, if surpass, then move to step P15, make 21 outages of front side heater, if do not surpass, then move to step P16, with above-mentioned current on time to front side heater 21 control of switching on.
Then, move to step P17, whether the detected temperatures of judging inboard temperature sensor 26 surpasses the fiducial temperature HK of heater portion, if surpass, then move to step P18, make inboard heater 22 outages and give heater 29 energisings down, if do not surpass, then move to step P19, give inboard heater 22 energisings and make down heater 29 outages.
At step P20, judge whether the detected temperatures of cook temperature sensor 28 surpasses setting cook temperature KK, if surpass, then move to step P21, make whole heaters 21,22,29 outages, return step P20 through step P22.That is, during the cooking time of setting is without mistake, wait for that the temperature in the cooking chamber 4 reduces.Whether then, the temperature in the cooking chamber 4 drop to sets cook temperature KK when following, moves to step P23, judge cooking time of setting process, if process then moves to step P24, whole heaters 21,22,29 is cut off the power supply, and returns main program; If process is not then returned step P14.
The moment t3 of Figure 11 is the detected temperatures of front side temperature sensor 25 when having surpassed the fiducial temperature HK of heater portion, at this moment, makes front side heater 21 outages (at this moment, the detected temperatures of cook temperature sensor 28 is being set below the cook temperature KK).
Constantly t4 be the temperature of inboard heater 22 when the fiducial temperature HK of heater portion is following, at this moment, inboard heater 22 energisings, following heater 29 outages.
Constantly t5 be the detected temperatures of front side temperature sensor 25 when the fiducial temperature HK of heater portion is following, at this moment, with predetermined current on time to front side heater 21 control of switching on.
Constantly t6 is the detected temperatures of inboard temperature sensor 26 when surpassing the fiducial temperature HK of heater portion, at this moment, makes inboard heater 22 outages, following heater 29 energisings.
Constantly t7 is the detected temperatures of cook temperature sensor 28 when having surpassed setting cook temperature KK, at this moment, and all heaters 21,22,29 outages.Afterwards, the detected temperatures of cook temperature sensor 28 reach set cook temperature KK before, no matter the detected temperatures of front side temperature sensor 25 and inboard temperature sensor 26 is how, all heaters 21,22,29 are keeping off-position.
Constantly t8 is that the detected temperatures of cook temperature sensor 28 is being set cook temperature KK when following, at this moment, carve at this moment, among the step P20 be " N ", arrive step P14, because the detected temperatures of front side temperature sensor 25 is higher than the fiducial temperature HK of heater portion through step P23, so front side heater 21 still keeps outage, because the detected temperatures of inboard temperature sensor 26 is lower than the fiducial temperature HK of heater portion, so move to step P19 through " Y " of step P17, inboard heater energising.
Like this, when smoking the cooking, heater 29 was energized under front side heater 21, inboard heater 22 reached, and front side heater 21 is controlled as identical approximately input with inboard heater 22.And heater 29 is energisings when inboard heater 22 cuts off the power supply down.Therefore, all not energisings simultaneously of heater 21,22,29.
In the main program of Fig. 6,, then move to step S8 if selected the roasting cooking.Fig. 8 represents the control content of this step S8.
At first, at step G1, in the time of 21 energisings of front side heater, inboard heater 22 is also switched on.Just be heated gradually in the cooking chamber 4.Beginning not pass through the predetermined detection cycle from this cooking for example (judges at step G2) during 30 seconds, whether the cooking time that judgement cooking time setting switch is set passes through (step G3), if process then makes 21,22 outages (step G4) of two heaters, return main program; If do not pass through, whether the detected temperatures of then judging front side temperature sensor 25 or inboard temperature sensor 26 surpasses the fiducial temperature HK ' of heater portion (at this moment all being set at predetermined temperature) (step G5), if do not surpass, judge then whether the detected temperatures of cook temperature sensor 28 surpasses predefined cook temperature KK ' (step G6).At this step G6, surpassed setting cook temperature KK ' if be judged as the detected temperatures of cook temperature sensor 28, then make 21,22 outages (step G7) of two heaters, move to step G11 described later; If do not surpass, then return step G2.
Be as above-mentioned step G2, step G3, step G5, step G6 under the situation of " N ", carry out the closed loop of these steps, promptly wait for 30 seconds time.After 30 seconds, move to step G8, judge whether the detected temperatures of inboard temperature sensor 26 surpasses the detected temperatures of front side temperature sensor 25, if surpass, then moves to step G9, make inboard heater 22 outages; If do not surpass, then move to step G10, make inboard heater 22 energisings.
Above-mentioned 30 seconds of every process, with regard to execution in step G8, step G9 or step G10, like this, when the temperature in cooking chamber 4 edged up, the temperature of front side heater 21 and inboard heater 22 parts also rose.
When the detected temperatures of front side temperature sensor 25 or inboard temperature sensor 26 surpasses the fiducial temperature HK ' of heater portion (step G5), perhaps the detected temperatures when cook temperature sensor 28 surpasses setting cook temperature KK ' time (step G6), the control that execution in step G11 is later.
That is,, judge whether the detected temperatures of front side temperature sensor 25 surpasses the fiducial temperature HK ' of heater portion,, then move to step G12, make 21 outages of front side heater if exceed at step G11; If do not surpass, then move to step G13, make 21 energisings of front side heater.
Then, move to step G14, judge whether the detected temperatures of inboard temperature sensor 26 surpasses heater fiducial temperature HK ',, then move to step G15, make inboard heater 22 outages if surpass; If do not surpass, then move to step G16, make inboard heater 22 energisings.
At step G17, judge whether the detected temperatures of cook temperature sensor 28 surpasses setting cook temperature KK ', if surpass, just move to step G18, make 21,22 outages of two heaters, return step G17 through step G19.That is, during the cooking time of setting is without mistake, wait for that the temperature in the cooking chamber 4 descends.Whether afterwards, temperature descend and reach and set cook temperature KK ' when following in the cooking chamber 4, move to step G20, judge cooking time of setting process, if process just moves to step G21, make 21,22 outages of two heaters, return main program; If process is not then returned step G11.
Therefore, in the roasting cooking, following heater 29 no powers, front side heater 21 is controlled to be identical approximately input with inboard heater 22.
In addition, if in the main program of Fig. 6, selected the baking cooking, then move to step S9.Fig. 9 represents the control content of this step S9.
At first, at step G1, when inboard heater 22 was switched on, following heater 29 was also switched on.Then,, judge to set cooking time process whether,, inboard heater 22 and following heater 29 are cut off the power supply if process just moves to step G3 at step G2.
As seen from the above description, smoke, the heater control when roasting and baking substantially as shown in figure 10 mode carry out.Promptly, when smoking the cooking, the main front side heater 21 that uses among front side heater 21 and inboard heater 22, inboard heater 22 controls become the input with front side heater 21 same degree, the outage when inboard heater 22 energisings, outage of following heater 29, energising.
