The culinary cooking program of being stored among the ROM72 of Fig. 7 for expression control device 70 of heater steam (cooking program), the CPU71 of control device 70 calls the culinary cooking program of heater steam from ROM72 when the content of operation according to switch 61 detects the cooking of selected heater steam, according to this cooking program control cooking content.Below, the culinary cooking program of heater steam is described.
At step S1, CPU71 drives internal heater 17, heater 18 outside step S2 drives.Control these internal heaters 17 and outer heater 18 according to the ON/OFF that is pre-stored among the ROM72 than (ON/OFF ratio), the ON/OFF of step S1 internal heater 17 when outside step S2 the ON/OFF of heater 18 be the maximum that its output is set at specified output than all.
At step S2, when CPU71 drove outer heater 18, at step S3, fan drive motor 11 was switched on hot blast is circulated in cooking room 4.Then, at step S4, detect the temperature inside the box of cooking room 4 according to the output signal of the temperature inside the box sensor 20, at step S5, the testing result of the temperature inside the box is compared with the preheat temperature (for example 100 ℃) that is pre-stored in ROM72, here, go to step S6 when the testing result that detects the temperature inside the box arrives preheat temperature, internal heater 17 stops.Then, at step S7, outer heater 18 stops, and again at step S8, stops the do action that fan drive motor 11 is interrupted hot blast.
At step S8, when CPU71 stops fan drive motor 11,, drive evaporation heater 40 at step S9, at step S10, drove hot heater 41.According to being pre-stored in the ON/OFF ratio above-mentioned evaporation heater 40 of control among the ROM72 and crossing hot heater 41.The ON/OFF of the evaporation heater 40 of the step 9 when ON/OFF of crossing hot heater 41 of step 10 is the maximum that its output is set at specified output than all.Be evaporation heater 40 and cross hot heater 41 according to the running of maximum output can fan drive motor 11, internal heater 17, and the hot air circulation that all stops of the outer heater 18 threes interrupt status of moving under carry out.
In step 10, when CPU71 drove hot heater 41, go to step 11.In this step, detect the room temperature that steam generates chamber 34 according to the output signal of vapor (steam) temperature sensor 59, at step S12, the testing result and the steam that is pre-stored in ROM72 of room temperature is generated temperature (for example 120 ℃) compare.In this step, when arriving steam generation temperature, the testing result that detects room temperature goes to step S13, evaporation heater 40 outages.This heater steam cooking method is because the prior heating steam of hot blast of using the cooking mechanism 19 of heat cooking apparatus to generate generates container 31, so in step 12, the room temperature of steam generation chamber 34 arrives steam at short notice and generates temperature.Just, in steam generates chamber 34, arrive steam generation temperature and had only hot heater 41 to be continued to drive later on, only leaned on the output of hot heater 41 that the temperature maintenance that steam generates in the chamber 34 is generated temperature at steam.This steam generation temperature is equivalent to water filling and begins temperature.
As shown in Figure 8, the water filling data prestore among the ROM72 of control device 70.These water filling data are except record evaporation heater 40 and cross the rotating speed that also writes down pump drive motor 37 both user modes of hot heater 41, when CPU71 goes to step S14 at the step S13 from Fig. 7, from the water filling data, detect and both corresponding rotating speeds of user mode of evaporation heater 40 and mistake hot heater 41.In this case, used hot heater 41 separately, so detect the rotating speed of medium speed as pump drive motor 37.The user mode of above-mentioned evaporation heater 40 and mistake hot heater 41 is equivalent to operating condition.
In the step S14 of Fig. 7, when CPU71 detects the medium speed as the rotating speed of pump drive motor 37, at step S15, with medium speed's driving pump drive motor 37.The speed setting of this pump drive motor 37 becomes will drop on the water yield that steam generates the instant water evaporation of 34 bottom surfaces, chamber and injects steam and generate value in the chamber 34, in step 15, and with intermediate flow water filling in steam generates chamber 34, the steam of generation intermediate flow.
At step S15, when CPU71 driving pump drive motor 37,, drive internal heater 17 once more at step S16, at step S17, drive outer heater 18 once more, at step S18, drive fan drive motor 11 circulates hot blast in cooking room 4 once more.The ON/OFF ratio that all prestores by ROM72 that drives once more that reaches outer heater 18 that drives once more of above-mentioned internal heater 17 is controlled, and the ON/OFF of the internal heater 17 of the step 16 when ON/OFF ratio of the outer heater 18 of step S17 is all set the value that output is lower than the low output of specified output for.The culinary common running that is internal heater 17 and outer heater 18 is carried out with the state that only drove hot heater 41.
At step S18, as CPU71 once more during drive fan drive motor 11, the cooking that goes to step S19 is handled.This cooking is treated to the limit makes hot blast circulation limit in cooking room 4 supply with steam, in cooking room 4 for through reaching from the heat of crossing hot heater 41 from the steam after both hot overheated of the heat of hot blast, steam and the hot blast supplied with in the cooking room 4 circulate together, and be overheated by internal heater 17 and outer heater 18 again.During this cooking is handled internal heater 17 and outer heater 18 being made switch controls and makes the output signal of the temperature inside the box sensor 20 converge on cook temperature, speed to pump drive motor 37 is controlled, be controlled to the certain medium speed corresponding, carry out switch control and make the output signal of vapor (steam) temperature sensor 59 converge on steam to generate temperature crossing hot heater 41 with using hot heater 41 separately.
When CPU71 goes to step S20, judge the end of cooking condition that has or not establishment.Here go to step 21 when the end of cooking condition is set up detecting, make fan drive motor 11, internal heater 17, outer heater 18, fan drive motor 37, reached hot heater 41 and stop heater steam end of cooking.
