In one embodiment of microwave oven defrosting control method of the present invention, with reference to Fig. 2, microwave oven defrosting control method include with
Lower step：
Step S10, in micro-wave oven treats thawed foodstuff progress course of defrosting, detection micro-wave oven carrying waits for thawed foodstuff
The bottom temp of vessel；
Micro-wave oven is the common electric for heating or cooking, micro-wave oven generally comprise power supply, microwave source (such as magnetron),
Heating chamber, fire door etc..Wherein, microwave source is the core component for generating microwave, mainly generates microwave by the excitation of high voltage power supply,
By waveguide transmission and it is coupled to place and waits in the heating chamber of thawed foodstuff.Since traditional micro-wave oven is usually to thaw to eat to band
Object carries out lasting and prolonged microwave heating, it is easy to make to wait for thawed foodstuff because power is excessive when magnetron being caused to work
Certain position (such as surface) overheats, generate microwave focus issues, and other positions (as internal) of hot food to be added are also in knot
Ice-like state.
Therefore in embodiments of the present invention, with reference to Fig. 6, micro-wave oven middle part is offered for accommodating the heating chamber for waiting for thawed foodstuff
And processor, the bottom setting carrying of heating chamber wait for the vessel of thawed foodstuff, the vessel and the contact area for waiting for thawed foodstuff
For fluorescent ceramic material, the contact area bottom is provided with temperature measurement component, and temperature measurement component includes the optical fiber for exporting blue light, setting
Optical fiber one end transmitter and the light guide in the optical fiber other end is set, the light guide is established between thermometric region and optical fiber
Light-path, the optical fiber, transmitter are electrically connected with processor, and optical fiber can be fixed on micro-wave oven by optical fiber fixed card buckle and add
On the ceramic bottom board in hot bottom of chamber portion, which can be guide-lighting wedge, optical fiber concretely optical fiber probe.
Waiting in thawed foodstuff placing ceramic vessel, as shown in Figure 6.The pottery passes through special processing, vessel bottom
It is sintered fluorescent ceramic material, which will produce red fluorescence after being excited by the blue light in optical fiber.Optical fiber is visited
Needle is fixed on microwaveceramic bottom plate in the following, being used for communicating optical signals by special fastening.Guide-lighting wedge arrives the light reflection in optical fiber
On the fluorescent ceramic material of vessel, while in the reflection to red light back into optical fibers of fluorescent ceramic material excitation, in addition optical fiber connects on one side
Enter transmitter, is handled by transducer signal and calculate temperature value.Since fluorescent ceramic material is temperature sensing material, work as fluorescence ceramics
After material temperature changes, the red fluorescence service life being excited will change, and transmitter can be resolved according to fluorescence lifetime characteristic
Go out temperature value.In addition, it is emphasized that the temperature value that optical fiber probe measures gained is the temperature value of vessel bottom, due to food and device
Ware bottom contacts, and after hot transmission/diffusion balance, food temperature will be approached with the temperature of vessel bottom, therefore optical fiber probe is surveyed
The temperature value of amount is bottom temp.
In addition, guide-lighting wedge is typically mounted at microwaveceramic bottom plate center, for light transmission, the position of contact base plate is saturating
It is bright, without silk-screen.Due to requiring temperature between -2~35 DEG C after food thawing, uniformity leads to hot-spot in order to prevent, can
It is 15 DEG C that thermostatically controlled pre-set target temperature, which is arranged, the bottom temp of the vessel bottom then measured according to temperature measurement component with
Carry out thermostatic control.
When micro-wave oven starts to heat the band thawed foodstuff in heating chamber, starts temperature measurement component and wait thawing to detect
The bottom temp of food.It is of course also possible to be that user starts micro-wave oven intelligence defrosting function or micro-wave oven detects the food being put into
Temperature is relatively low and starts intelligent defrosting function automatically, starts to execute microwave oven defrosting control method of the present invention, starts to detect and wait solving
Freeze the bottom temp of food.
Step S20 obtains the temperature gap of pre-set target temperature and bottom temp, is turned down step by step according to the temperature gap
Micro-wave oven treats the firepower gear that thawed foodstuff thaws；Wherein temperature gap is bigger, and corresponding micro-wave oven firepower gear is got over
It is high；The firepower gear of micro-wave oven is higher, and the heating power of micro-wave oven output is higher；
In detecting micro-wave oven after the bottom temp of thawed foodstuff, pre-set target temperature is obtained.Pre-set target temperature
It is to realize the basis for taking micro-wave oven heated at constant temperature one-dimensional FUZZY ALGORITHMS FOR CONTROL, that is, controls the heating power of micro-wave oven, it is real
Existing hot food to be added bottom temp in micro-wave oven maintains near pre-set target temperature.Pre-set target temperature and bottom are calculated first
The temperature gap of portion's temperature, such as pre-set target temperature are 15 DEG C, and bottom temp is 10 DEG C, then temperature gap is 5 DEG C.According to temperature
Degree difference turns micro-wave oven down and treats the firepower gear that thawed foodstuff thaws step by step, and temperature gap (positive value) is bigger, shows to wait for
The bottom temp of thawed foodstuff is very low, internal ice crystal is more, is added with larger heating power at this time, it may be necessary to control micro-wave oven
Heat, i.e., corresponding micro-wave oven firepower gear are higher.
Specifically, step S20 includes：
Step S21 is dynamically determined real-time where temperature gap by temperature gap compared with preset temperature range list
Real-time firepower gear corresponding to temperature difference section and the real-time temperature difference section；
Step S22, dynamic control micro-wave oven treat thawed foodstuff with real-time firepower gear and thaw
Preset temperature range list may include that multiple temperature ranges, temperature range are numerical intervals, such as temperature range
List includes that three temperature ranges or five temperature ranges judge temperature gap place according to the numerical values recited of temperature gap
Real time temperature section belong to the numberical range of which temperature range, that is, be dynamically determined real-time where different moments temperature gap
Temperature range, and based on the mapping of the temperature range and firepower gear (firepower gear is higher, and heating power is bigger) that are previously set
Relationship further determines that the corresponding real-time firepower gear in each real time temperature section.To treat adding for thawed foodstuff in micro-wave oven
In thermal process, dynamic control micro-wave oven is under different moments, with the corresponding real-time firepower in real time temperature section where temperature gap
Gear treats thawed foodstuff and thaws, to realize that the segmentation to temperature gap divides with accurate, independent temperature range, from
And realize to the Discrete control of firepower gear under micro-wave oven different temperatures difference, it avoids waiting for thawed foodstuff because of micro-wave oven firepower gear
Excessive, heating power is excessive and local temperature is excessive, part burns or becomes ripe.
Step S30, when the firepower gear of micro-wave oven is in default small fire gear, adjustment micro-wave oven, which is in, presets small fire screen
Thermostatic control of the thawed foodstuff in pre-set target temperature is treated in the make-to-break ratio of position, realization；
During micro-wave oven treats the heating and defrosting of thawed foodstuff, wait for that the bottom temp of thawed foodstuff gradually rises simultaneously
Pre-set target temperature is moved closer to, (the such as less than fiducial temperature when the temperature gap very little of pre-set target temperature and bottom temp
Minimum, fiducial temperature minimum can be positive and negative 0.1 DEG C), the firepower gear for adjusting micro-wave oven is default small fire gear, is waited at this time
Most of ice crystal inside thawed foodstuff has melted, without absorbing a large amount of latent heat, wait at this time the bottom temp of thawed foodstuff with
Pre-set target temperature remains basically stable, temperature change is more sensitive, and microwave focuses the hot-spot with food in order to prevent at this time, micro-
The firepower gear and output power of wave stove also need to become smaller therewith, and micro-wave oven is finally using presetting small fire gear, when waiting for thawed foodstuff
Bottom temp be more than pre-set target temperature, then close micro-wave oven；When wait for thawed foodstuff bottom temp be less than goal-selling temperature
Degree is then opened micro-wave oven and is worked with default small fire gear, is heated and is thawed to continue to treat thawed foodstuff, so cycle is anti-
It is multiple；That is when micro-wave oven is in default small fire gear, adjustment micro-wave oven is in the make-to-break ratio of default small fire gear, realizes
Treat thermostatic control of the thawed foodstuff in pre-set target temperature.When make-to-break ratio is micro-wave oven operating time (energization period) and closes
The ratio between long (power-off duration).
Step S40, when the make-to-break ratio that micro-wave oven presets small fire gear is less than default break-make threshold value, stopping micro-wave oven treating solution
Freeze the defrosting of food.
Thawed foodstuff is treated with default small fire gear with micro-wave oven and is heated and closed switching, waits for the bottom of thawed foodstuff
Portion's temperature is moved closer to internal temperature, waits for that the thermal equilibrium state inside thawed foodstuff is gradually built up, at this time micro-wave oven is with pre-
If the heating duration t1 of small fire gear is shorter and shorter, micro-wave oven closes duration t2 (namely when thermal diffusion inside thawed foodstuff
Long t2) it is increasingly longer, the make-to-break ratio (i.e. t1/t2) that micro-wave oven presets small fire gear is smaller and smaller, when micro-wave oven presets small fire screen
The make-to-break ratio of position is less than default break-make threshold value (can be determined according to many experiments), shows to wait for be established inside thawed foodstuff default
Thermal equilibrium state at target temperature, stops the defrosting that micro-wave oven treats thawed foodstuff, and the course of defrosting of micro-wave oven terminates.
In the present embodiment, it in the course of defrosting that micro-wave oven treats thawed foodstuff, according to pre-set target temperature and waits solving
Freeze the temperature gap of food bottom temp, controls the firepower gear that micro-wave oven thaws, and in micro-wave oven to preset small fire screen
During position is thawed, the make-to-break ratio of small fire gear heating power is preset in adjustment micro-wave oven output, and defrosting food is treated in realization
Object pre-set target temperature thermostatic control, in course of defrosting, because waiting for the bottom temp of thawed foodstuff than food
Internal temperature wants high, and IR thermometry directly measures the bottom temp of foodstuff surface, therefore waits for the bottom on thawed foodstuff surface
Temperature is controlled in pre-set target temperature, waits for that the internal temperature of thawed foodstuff should be less than pre-set target temperature, despite the presence of microwave
The temperature of focusing waits for that the inside and outside temperature difference of thawed foodstuff is not more than 10 DEG C, and pre-set target temperature is arranged at 10 DEG C to 20 DEG C
It then can guarantee and wait for thawed foodstuff not more than 30 DEG C of surface temperature in course of defrosting, therefore avoid and wait for thawed foodstuff part
It overheats and becomes ripe problem；Also, it is pre- using transformation micro-wave oven due to being in default small fire gear course of defrosting in micro-wave oven
If small fire gear make-to-break ratio, thermostatic control of the thawed foodstuff in pre-set target temperature is treated, course of defrosting waits for ginseng without user
With food turn-over, solves the very big pain spot that user waits for Attended Operation, the operation for enormously simplifying thawing food in microwave oven is multiple
Miscellaneous degree.
Further, in another embodiment of microwave oven defrosting control method of the present invention, step S21 includes：
Step S211 adjusts fire in real time when temperature gap is in the first temperature range for being more than default extreme delta value
Power gear is default big fire gear；
Step S212, when temperature gap is for negative or in less than the second temperature section for presetting minimum temperature difference,
It is out of service to control micro-wave oven；
Step S213, when except temperature gap being in the first temperature range and second temperature section, temperature difference
The target temperature difference section at place, using the corresponding firepower gear in target temperature difference section as current real-time firepower gear.
Endothermic process in thawed foodstuff course of defrosting is waited in order to assist understanding, in food freezing process introduced below, food
(such as meat) exothermic Computing Principle.
By taking meat as an example, for meat in freezing process, the heat Calculation that meat is released is following formula (1)：
Q=m [cp1(T1-Tp)+ωψr+cp2(Tp-T2)] (1)
Wherein Q is gross energy, and m is the quality of meat, Cp1And Cp2Respectively meat freezes front and back specific heat capacity, and ψ is to freeze
Rate, r are the latent heat that water forms ice, T1、Tp、T2Respectively initial temperature, phase transition temperature, final temperature, ω can be error coefficient
(can be arranged according to external environments such as air pressure, height above sea level).It can be seen that when meat freezes, it includes 3 parts to release energy mainly, with reference to figure
3, the exothermic phase L1 before moisture does not freeze in meat, water releases heat in the L1 stages are mainly meat；Followed by meat
Moisture is changed into phase transformation exothermic phase L2 simultaneously, and water phase becomes ice releasing heat in the L2 stages are mainly meat；It is finally meat
Ice continues the exothermic phase L3 of cooling in class, as can be seen from Figure 2, in meat freezing process, phase transformation exothermic phase L2 latent heat maximum,
Exotherm Time longest.Also, meat is put into -18 DEG C of refrigerator freezing chamber progress and freezes, and the freezing rate of water is 90% in general meat
Or so, in the meat freezed other than most water becomes ice crystal, still there is the water of fraction not freeze.
Meanwhile the course of defrosting of food be freezing process inverse process, i.e., heat absorption of the food in course of defrosting just with
3 stages of heat release correspond in freezing process.During food thawing, the microwave of food absorption micro-wave oven release is to be inhaled
Heat.
The microwave heating principle of micro-wave oven is according to following formula (2)：
Q=55.6 × 10-12E2fVε″rΔ t=mcpΔT (2)
Wherein, E is electromagnetic field intensity, and f is microwave frequency, and V is volume, and Δ t is heating time, and Δ T is Wen Sheng, CpFor than
Thermal capacitance, ε "rFor dielectric loss factor, then it is following formula (3) that temperature, which rises slope k (temperature rise rate i.e. in the unit interval),：
The dielectric loss factor of ice is much larger than in view of the dielectric loss factor of water, the dielectric loss factor of -13 DEG C of ice is
The dielectric loss factor of 0.0028,25 DEG C of ice is 12.3, and the specific heat capacity of ice is the half of water, and the specific heat capacity of water is 4.2kJ/
(kg* DEG C), ice are 2.1kJ/ (kg* DEG C), therefore according to formula (3) with lower inequality (4)：
Based on inequality (4) it is found that the ratio of the specific heat capacity of the dielectric loss factor and water of water is far longer than the dielectric of ice
The ratio of fissipation factor and the specific heat capacity of water can also be released, water temperature rise slope (i.e. in the unit interval of water temperature raising speed
Rate) it is far longer than the temperature liter slope (i.e. temperature rise rate in the unit interval of water) of water.
Based on above-mentioned explanation content, the defreezing by microwave oven intelligent control of the present embodiment include mainly the big fire heating period, in
Fiery heating period and small fire heating period.
I, the big fire heating period：
The starting stage that thawed foodstuff thaws in microwave stove heat is waited for, due to waiting in thawed foodstuff (such as meat) containing a large amount of
Ice crystal and minimal amount of water, wait for that thawed foodstuff is very low for the absorption of microwave at this time, micro-wave oven it is high to freezing rate wait thawing
Food microwave heating is less efficient, and therefore, with reference to Fig. 4 and Fig. 5, in the defrosting starting stage, (i.e. temperature gap is in be more than and preset
First temperature range of extreme delta value, it can be 10 DEG C to preset tremendous temperatures difference), micro-wave oven is to preset big fire gear (such as
It 600W) is heated, by frequency conversion vigorous fire ice-breaking, that is, undergoes the big fire heating period.I.e. micro-wave oven carries out big fire heating rank first
Section, setting micro-wave oven heated in real-time power are p6 watts (p6 600W), and control micro-wave oven, which starts to treat thawed foodstuff, to be heated.
In fact micro-wave oven big fire heating period, mainly heating wait for a small amount of water in thawed foodstuff, pass through after water heating
Heat, which is transmitted, makes ice gradually melt.The thermal conductivity of water is 0.582W/ (m*k), the thermal conductivity of ice is 2.326W/ (m*k), about water
4 times, thus it is preferable by the heat transfer effect of ice, and the temperature rise ratio of hot food to be added is rapider in this stage.Work as goal-selling
Temperature is with when the temperature gap of the bottom temp of thawed foodstuff is less than default extreme delta value, and the microwave of food is poly- in order to prevent
Burnt and hot-spot, needs to turn down the firepower gear of micro-wave oven, that is, the heated in real-time power of micro-wave oven is turned down, with automatic
Into subsequent moderate heat or small fire heating period.
II, moderate heat heating period：
After micro-wave oven is with default big fire gear short time heating, when pre-set target temperature and bottom temp are very big less than default
Temperature difference and more than preset minimum temperature difference when, show to wait for that ice crystal gradually melts in thawed foodstuff (such as meat), food inside and outside
Heat transference efficiency constantly decline, wait for thawed foodstuff hot-spot in order to prevent at this time, continue the heating power for turning down micro-wave oven,
The moderate heat heating period can be divided into one or more gear firepower, and for example, referring to Fig. 4 and Fig. 5, the moderate heat heating period is divided into four ranks
Section, setting temperature gap is dt, as 8 DEG C≤dt<At 10 DEG C, microwave oven output power is the corresponding firepower gears of P5 (such as 500W)；
As 6 DEG C≤dt<At 8 DEG C, microwave oven output power is the corresponding firepower gears of P4 (such as 400W)；As 4 DEG C≤dt<At 6 DEG C, micro-wave oven
Output power is the corresponding firepower gears of P3 (such as 300W)；As 2 DEG C≤dt<At 4 DEG C, microwave oven output power is that P2 (such as 200W) is right
Answer firepower gear.When temperature gap further decreases, such as 0.1 DEG C≤dt<At 2 DEG C, to ensure to wait for the constant temperature of thawed foodstuff
It thawing, microwave oven output power need to be further reduced to P1 (such as 100W), and P1 is the microwave oven output power of default small fire gear,
Enter the micro-wave oven small fire heating period.
III, small fire heating period：
Due to waiting for that the bottom temp of thawed foodstuff has risen to phase transition temperature, wait in thawed foodstuff most ice crystals gradually into
Enter solid-liquid phase change state, wait for that thawed foodstuff inside and outside temperature difference and heat transference efficiency further decrease, and waits thawing in order to prevent
Microwave focuses and leads to homogeneous heating sex chromosome mosaicism, need to further turn the heating power (or output power) of micro-wave oven down, i.e., micro-
Wave stove is adjusted to default small fire gear.When the temperature gap between pre-set target temperature and real-time bottom temp further subtracts
It is small, as temperature gap dt is in -0.1 DEG C≤dt<0.1 DEG C and dt is in dt<- 0.1 DEG C, i.e., when temperature gap be negative or
When in less than the second temperature section for presetting minimum temperature difference, control micro-wave oven is out of service.To realize adjustment micro-wave oven
Make-to-break ratio in default small fire gear, realization are treated thermostatic control of the thawed foodstuff in pre-set target temperature, are being heated in this way
Process intermittent diffusion time is longer, is conducive to improve and waits for thawed foodstuff heating uniformity, prevents food thawing from becoming ripe.
It is right for characteristics such as heat absorption, the heat transference efficiencies of food thawing based on above-mentioned big fire, moderate heat, small fire heating period
