value, can be with equivalent to the setting value that each formula in the overall formula table of translation up or down walks temperature Same formula table is applied to different-thickness, the pan of unlike material, and thermocouple assembling deviation and thermocouple can be corrected The difference of itself, so that formula table is applied to pan." temperature control tolerance " characterizes the controlled object temperature of pan relative to culinary art journey The fluctuating range of desired temperature in formula；For example, temperature control tolerance is 2%, represent that pot controller allows the measured value of pot temperature (i.e. Controlled object temperature) relative value of maximum deviation of fluctuation range between pot temperature setting value is 2%, such as：If pot temperature Setting value be 200 DEG C, then the measured value (i.e. controlled object temperature) of pot temperature is between 196-204 DEG C, then it is assumed that pot temperature Measured value and pot temperature setting value it is suitable.The relative value of temperature deviation is defined herein as：Relative value=ABS of temperature deviation The setting value * 100% of (setting value of measured value-temperature of temperature)/temperature, the definition of relative value is similarly hereinafter." sampling period " table Levy pot controller obtained from formula table the setting value of temperature, the setting value of firepower control mode, the setting value of power ratio and The frequent degree that the time interval of the measured value of pot temperature, i.e. pot controller implement control to pot is obtained from thermocouple.Sampling week It is smaller that phase is set, and control of the controller to the

As second of the present invention embodiment there is provided a kind of Intelligent pan 100, as shown in figure 5, next only by the The technical scheme part distinguished of two kinds of embodiments and first embodiment is described in detail below.

The Intelligent pan 100, as shown in figure 5, also including overflow pot sensor 150 and water leg 160.The excessive pot sensor 150 mutually assemble with Intelligent pan 100, the excessive pot state for detecting pot, and pot state of overflowing can be understood as including liquid in pot and overflow The excessive pot state or overflow condition gone out possesses the excessive pot state that will be overflowed and not yet overflow.The water leg 160 is arranged on The top in pot body portion 111, the outside positioned at pot body portion 111, and it surround pot body portion 111 1 weeks, overflowed for collecting pot 110 The liquid come, it is to avoid the fluid dirt heater and the kitchen range top of spilling.The end face of water leg 160 can be with L-shaped, itself and pot body portion The U-shaped groove for being used to accommodate liquid is formed after 111 fixations.From the opposite side of lever 120 to the side of lever 120, water leg 160 The height relative to pot bottom gradually reduce, the height positioned at the water leg 160 of the side of lever 120 is minimum, in favor of water leg Liquid in 160 hitherward flows.The conduction hole (being not drawn into figure) flowed out for liquid, institute are equipped with water leg 160 State the lowest part that conduction hole is arranged on the height of water leg 160, that is to say, that conduction hole is located at the underface of lever 120.

Wherein, the excessive pot sensor 150 can select thermocouple.Constitute thermocouple and the pot body portion for the pot sensor that overflows 111 mutually fix, as shown in figure 5, the detection end of the thermocouple is arranged in water leg 160, positioned at the underface of lever, Such as it is arranged in conduction hole, is so laid out, the detection end of thermocouple can touch the liquid collected by water leg 160 in time Body, the excessive pot state that liquid overflows in pot can be detected in time, following excessive pots are carried out in time beneficial to pot controller 140 Processing.During culinary art, when excessive pot occurs, the liquid flooding in Intelligent pan 100, the liquid of overflow comes together in water leg In 150, and flowed at conduction hole, the liquid that the measurement end of thermocouple goes out into contact with overflow, the measurement end of thermocouple Temperature quickly change, the temperature curve that thermocouple is detected is undergone mutation, formed step, can be used for judging Intelligent pan accordingly 100 occur the pot that overflows, and generate the state of excessive pot.Using thermocouple as excessive pot sensor 150, its cost is relatively low, but required Liquid in Intelligent pan 100 can just detect excessive pot after overflowing, it is determined that the state of produced excessive pot, and intelligence can not be detected The excessive pot condition of pot 100 possesses the state that will be overflowed and not yet overflow.For example, Intelligent pan 100 is heated by heater, in pot After liquid boiling, continue to be heated, will produce a large amount of foams in pot on the surface of liquid, the whole liquid surface of foam coverage, and The height of foam gradually rises afterwards, when the top end face and pot cover of foam are in contact, and now Intelligent pan possesses the excessive pot condition of generation, Will occur excessive pot, but have not occurred excessive pot, the thermocouple for constituting the pot sensor 150 that overflows be can not detect it is above-mentioned in pot The state of excessive pot, therefore the generation of excessive pot can not be avoided.

The above-mentioned thermocouple for pot detection of overflowing is substituted using ultrasonic sensor, the ultrasonic sensor is used to detect liquid Foam and its height, the problem of can solving above-mentioned well that body surface face is produced, are avoided that the generation of excessive pot.The ultrasonic wave Sensor is arranged on the top of pan, as shown in fig. 6, can be fixed as the ultrasonic sensor for the pot sensor 150 that overflows On Intelligent pan, on such as lever 120, the liquid phase pair in the detection end of ultrasonic sensor and pot；Alternatively, it is also possible to such as scheme Shown in 7, on the pot cover that ultrasonic sensor is fixed on to Intelligent pan 100, on the detection end of ultrasonic sensor and pot cover Detection window it is just relative.Ultrasonic sensor (or by detecting window) can detect what liquid surface in Intelligent pan 100 gathered Foam and its height.Pot controller 140 obtains the detection signal of ultrasonic sensor, the detection signal based on ultrasonic sensor The height of foam is determined, when foam height reaches height threshold, the liquid in Intelligent pan 100 will overflow and not yet overflow, Pot controller 140 makes the judgement of excessive pot state, and generates the control signal for reducing required firepower, and the control signal is sent out Described heater is given, heater generates control signal based on the control signal received, for reducing heater Firepower, foam height in Intelligent pan 100 is reduced even the removal of foam, it is ensured that excessive pot does not occur for Intelligent pan 100, keep plus Thermal and the kitchen range top it is clean and tidy.In addition, described ultrasonic sensor can also be by the photoelectric sensor institute for foam inspection side Substitute.Therefore, when the pot sensor 150 that overflows is from being used to detect the ultrasonic wave wave sensor or photoelectricity wave sensor of foam, Intelligent pan 100 overflow a pot condition possessed will overflow pot but not yet overflow pot when, pot controller 140 manipulate heater reduce firepower, The excessive pot condition of Intelligent pan 100 is eliminated, the pot that overflows can be avoided, and avoid the liquid soiled heater and stove of overflow Platform.

In addition, it is necessary to explanation, the excessive pot sensor 150, which can also be selected, is used for the supersonic sensing that displacement is detected Device or photoelectric sensor, the pot sensor that overflows are arranged on the top of Intelligent pan, as shown in fig. 7, it can be with Intelligent pan 100 Shank part 120 is mutually fixed, and it detects that the pot cover of end and Intelligent pan is just relative, is whether there is for detecting lid pot and is subjected to displacement.Work as intelligence When excessive pot occurs for energy pot 100, the pot cover of Intelligent pan will be moved, and as above and below, moved left and right, be subjected to displacement.Therefore, pot is worked as Detection signal of the controller 140 based on excessive pot sensor 150, based on the detection signal when determination pot cover has sent out displacement, then makes The judgement for pot state of overflowing is produced, now, generation control signal manipulation heater reduces firepower to pot controller 140 in time, eliminates The excessive pot condition of pot, it is possible to reduce or even avoid the generation of excessive pot.

Using the cooking food of Intelligent pan 100, in each control/sampling period, pot controller 140 obtains the pot sensor that overflows 150 detection signal, the detection signal based on excessive pot sensor 150 determines the state of the excessive pot of Intelligent pan.The pot base of controller 140 In overflow pot sensor 150 detection signal when it is determined that generating the state of excessive pot, generation make needed for heating firepower reduction Control signal, and the control signal is sent to heater, the controller of heater is based on the control signal life received It is used to manipulate heater reduction firepower into control signal, Intelligent pan is eliminated the pot that overflows, it is to avoid excessive pot proceeds；Pot control simultaneously Device processed carries out pot counting of overflowing.It is more than count threshold when excessive pot is counted, such as when the pot that overflows is counted more than 3 times, particularly occurs continuous When the pot that overflows is counted, pot is charged device 140 processed and has also carried out being handled with underflow pot.

It is more than count threshold when excessive pot is counted, pot controller 140 will be acquired with excessive pot moment institute from culinary art formula The setting value for walking temperature in the setting value and current formula of the corresponding pot temperature of controlling cycle is compared, and by the pot temperature The setting value that the setting value of degree walks temperature with current formula makees mathematic interpolation, and the difference is identified, and is such as identified as herein 1st adjustment magnitude.When the setting value of the acquired pot temperature corresponding with controlling cycle where the excessive pot moment is relative to current When the setting value of formula step temperature is relatively low, the setting value of pot temperature differs 5-10 between walking the setting value of temperature with the formula as described DEG C, the setting value for showing to cook formula step temperature in formula is too high, now, and pot controller 140 reduces the temperature in culinary art formula The setting value of deviant, makes the overall translation downwards of controlled object temperature of Intelligent pan 100, reduces the controlled object temperature of pot, with Reduce until eliminating the generation for the pot that overflows；The reduction amplitude of the setting value of the temperature offset value is referred to the 1st adjustment magnitude and entered Row determines that alternatively value is the partial quantity of the 1st adjustment magnitude, and such as reduction amplitude takes 1/3,1/2 or the 2/ of the 1st adjustment magnitude 3 etc..When the setting value of the acquired pot temperature corresponding with controlling cycle where the excessive pot moment is relative to formula step temperature Setting value it is higher when, differ 2-5 DEG C between the setting value for the temperature that the setting value of pot temperature is walked with current formula as described, that is, overflow When the setting value of pot temperature corresponding to pot moment controlling cycle walks the setting value of temperature close to current formula, pot controller Current formula walks the setting value of temperature in 140 reduction culinary art formulas, and reduces its desired temperature not less than formula step temperature The setting value of the temperature of each formula step of setting value is spent, reduces the speed that the setting value and pot temperature of intelligent pot temperature rise Rate, gradually reduces the firepower of heater, reduces until eliminating the pot that overflows；The reduction amplitude of the setting value of the formula step temperature can To be determined with reference to the 1st adjustment magnitude, the partial quantity of the 1st adjustment magnitude is chosen as, it is the 1st adjustment amount such as to reduce amplitude value 1/3,1/2 or 2/3 etc. of value.It should be noted that after excessive pot occurs, pot controller 140 can also reduce culinary art journey simultaneously The setting value of temperature offset value and current formula walk the setting value of temperature in formula, in such cases in order to avoid overshoot, cause Pot temperature is too low, then the reduction amplitude sum that the reduction amplitude of temperature offset value walks desired temperature with formula should be less than the 1st tune Whole value.140 pairs of culinary art formulas of pot controller are carried out after above-mentioned modification, and excessive pot is counted and handled into professional etiquette 0, recovers 0 and is worth.

The setting value of formula step temperature or/and the setting value of temperature offset value of 140 pairs of culinary art formulas of pot controller are carried out Reduce after modification, pot controller 140 carries out excessive pot and counted again, and the pot that overflows is counted when being more than count threshold, pot controller 140 is according to upper State method and change culinary art formula again, so circulation adjustment, until culinary art formula has been performed, completes whole cooking process.Cook After the completion of preparing food, user can preserve the culinary art formula that pot controller 140 is changed, in case using next time.

If the excessive pot sensor 150 is from described ultrasonic sensor or photoelectric sensor, overflow pot sensor 150 The foam and foam height or the mobile status of pot cover of liquid surface in pot are detected, the generation of excessive pot can be avoided.Such as, intelligence is worked as Liquid is heated to after boiling in energy pot 100, and liquid surface produces union poly bubble foam, when the height of foam reaches the height of setting During threshold value, such as foam tip face contact pot cover, then pot trend of overflowing is produced, and has the possibility for occurring excessive pot, pot controller 140 is made excessive The judgement for the excessive pot state that pot condition possesses, is generated to reduce the control signal of heating firepower, and is sent to heater, together When pot controller 140 carry out overflow a pot count.Heater is used to reduce and added based on the control signal received, generation control signal The firepower of thermal, decreases or even eliminates the foam produced in Intelligent pan 100, it is to avoid overflow pot.

The Intelligent pan of present embodiment is included built in pot, thermocouple, pot controller, excessive pot sensor and pot controller Cook formula.Thermocouple is assemblied in the pot bottom of pot, and the pot sensor that overflows is arranged on Intelligent pan.Pot controller is based on the pot that overflows The detection signal of sensor, makes the judgement of excessive pot state, and carries out pot processing of overflowing, and reduces and even avoids the pot that overflows again.It is described Pot controller collection is overflow the detection signal of pot sensor, based on the detection signal of excessive pot sensor, when it is determined that pot there occurs it is excessive During the state of pot, the judgement of excessive pot is made, the generation of pot controller makes the control signal that required firepower reduces, and by the control signal Described heater is sent to, the controller of heater, which is based on control signal generation control signal, to be used to reduce heating dress The firepower put, weakens pot condition of overflowing, and eliminates the excessive pot of pot.Meanwhile, pot controller carries out pot counting of overflowing, and is more than meter when excessive pot is counted Number threshold value when, pot controller reduce culinary art formula in temperature offset value setting value, or/and reduce culinary art formula in excessive pot The setting value and desired temperature for occurring the temperature of corresponding formula step are not less than the temperature that each formula of formula step is walked The setting value of degree, occurs to decrease or even eliminate excessive pot.The excessive pot state includes the state that liquid overflows in pot, such as uses thermoelectricity Occasionally as excessive pot sensor, foam height reaches that the excessive pot condition of height threshold possesses the state for the pot that not yet overflows in pot, such as uses The excessive pot sensor of foam detection, and pot cover produce the state for moving the pot that will overflow, and are such as sensed using the excessive pot of displacement detecting Device.
