The application provides a kind of cooking methods, leads to poor heating with heat-generating disc poor contact with pot including solution and blowsThe problem of thermal cut-off.When what this cooking methods was substantially taken is the temperature change and heating of pot or internal food materials in controllingBetween the method that combines.When interior pot and heat-generating disc poor contact, poor thermal conductivity, it is reacted to and appears in certain add in temperatureIn the hot time, interior pot bottom temperature change is too big, and internal temperature variation is too small, does not reach the temperature spot of setting.It needs to stopIt only heats, or switchs to low-power heating, to reduce heat-generating disc temperature, prevent thermal cut-off from fusing.
Using a kind of electric pressure cooking saucepan (not shown) of the application cooking methods, including interior pot, pot cover and heating device, this is interiorThere is sealing ring to form cooking cavity therebetween between pot and pot cover, is equipped with the first temperature element on the outside of the interior pot bottomTo detect the temperature of above-mentioned cooking cavity bottom outside, the pot cover is equipped with the second temperature element protruded into the cooking cavity,To detect the temperature inside the cooking cavity.The heating device is heating dish, is arranged in the interior the bottom of a pan side, in addition the interior the bottom of a panFace is additionally provided with thermal cut-off, and when being when the temperature is excessively high more than the fusing-off temperature of the thermal cut-off, which fuses, and breaksSwitch power supply avoids the electric pressure cooking saucepan that fire occurs.The cooking apparatus is equipped with circuit board, which is equipped with multiple journeysSequence, a program at least within are able to carry out the cooking methods of the application.
As shown in connection with fig. 1, below by detailed the application cooking methods.The cooking cavity is heated with the first power first, is heatedThe preceding initial temperature Tb0 for obtaining the cooking cavity bottom outside and the initial temperature Tt0 in cooking cavity, the first power can be full functionRate, 900-1000 watts.After heating and continuous one first preset time, the medium temperature Tb1 of cooking cavity bottom outside at this time is obtainedAnd the medium temperature Tt1 in cooking cavity, and be compared with aforementioned Tb0 and Tt0, if Tb1 rises above the first temperature compared to Tb0Range, and Tt1 is lower than second temperature range compared to Tt0 heating, wherein the first temperature range is greater than second temperature range, then sentencesDisconnected the case where there are poor heatings, the second power used instead lower than the first power continues to heat；Conversely, then using above-mentioned first functionRate continues to heat.
Wherein, first temperature range is 40 °, and second temperature range is 20 °.The determination of the value of the two temperature is by sending outObtained by bright people's test of many times, the case where capable of accurately reacting with the presence or absence of poor heating.If beginning to warm up in certain time, the bottom of a panPortion rises above 40 °, and heating is not above 20 ° in pot, it can be determined that it is undesirable existing with heating means touch that there are interior potsAs, thus in pot food can not good absorption heat, cause in turn pot bottom heating it is too fast, need to control heating power,It is then heated instead below the second power of the first power, the pot bottom too fast thermal cut-off for leading to pot bottom that heats up is avoided to blow.
First preset time is 6-12 seconds.Test of many times according to inventor is verified, if there is poor heatingSituation, 6-12 seconds heating times can cause Tb1 ratio Tb0 to rise above 40 ° and Tt1 ratio Tt0 heating lower than 20 °, the timeIt is too short it cannot be determined whether there are the situation of poor heating, it is too long to may result in thermal cut-off fusing.Second power isInterruption heating, takes heating to stop within 15-25 seconds 20-40 seconds modes.It is heated using interruption, controls temperature rise, can avoid pot bottomIt heats up and too fast thermal cut-off is caused to fuse.
Using above-mentioned second power continue heating when, still want real-time detection cooking cavity bottom outside temperature Tb2 andTemperature Tt2 inside cooking cavity illustrates the bottom of a pan when Tb2 ratio Tb0 heating is lower than 40 ° or when Tt2 ratio Tt0 heating is greater than 20 °Temperature rise is too fast or pot in the excessively slow problem of temperature rise alleviated, heated condition has improved.Heating function can be adjusted accordingly at this timeRate is changed to the first power, to shorten cooking time.
When continuing heating using above-mentioned second power, even if not detecting Tb2 ratio Tb0 heating lower than 40 ° or Tt2It is greater than 20 ° than Tt0 heating, but heating time is up to after one second preset time, it is also desirable to adjust power again and be changed to above-mentioned first functionRate continues to heat.Equally, and avoid whole cooking time too long.Wherein second preset time is 3-8 minutes.It is too shortIf, bottom temp is excessively high still to will cause thermal cut-off fusing, if too long, will affect cooking time.
According to the application embodiment, when using the heating of the first power, real-time detection cooking cavity bottom outsideTemperature Tb3, if Tb3 be greater than a preset temperature, stop heating；Tb3 be less than the preset temperature after restore again with this firstPower heating.Real-time detection cooking bottom temperature, it is excessively high to stop heating, avoid thermal fuse-link fusing.The preset temperature is108 ° to 138 °.Specific value can according to quantity of food number and different settings.
It will be exemplified below, wherein the first preset time is 8 seconds, and the second preset time is 5 minutes, and preset temperature is115°.It is 15 ° that the initial temperature Tb0 of cooking cavity bottom outside, which is the initial temperature Tt0 in 20 ° and cooking cavity, before record heats,With 900 watts of the first power after heating power heating 8 seconds, the medium temperature Tb1 of cooking cavity bottom outside at this time is detectedIt is 62 °, rises above 40 ° compared to 20 ° of initial temperature, and the medium temperature Tt1 in cooking cavity is 30 °, it is initial compared to correspondingThe case where 15 ° of temperature heatings are lower than 20 °, judge that there are poor heatings, power is reduced, with the heating of the second power, i.e., with 900 watts,The 15-25 seconds modes for stopping 20-40 seconds of work heat.In the temperature Tb2 and cooking cavity of real-time detection cooking cavity bottom outsideMedium temperature Tt2 does not have found that Tb2 is greater than 35 ° lower than 60 ° or Tt2, until when reaching 5 minutes with the second power, again withThe heating of first power.During subsequent heat, real-time detection detects the temperature Tb3 of cooking cavity bottom outside, if Tb3 is greater than 115 °When, then stop heating；Restore again when Tb3 is less than 115 ° with first power heating.Whole process monitors the bottom of a pan and pot in real timeInterior temperature adjusts heating method, avoids cooking bottom temperature excessively high；Low-power continuous heating is also avoided to cause cooking time mistake simultaneouslyIt is long.
The application cooking methods and electric pressure cooking saucepan can judge whether there is heating not according to the temperature rise in bottom of pot body and potGood situation, and accordingly adjust heating power avoids the pot bottom too fast thermal cut-off for leading to pot bottom that heats up from blowing.
