Embodiment.
The present invention provides a kind of microwave oven defrosting control method, in an embodiment of microwave oven defrosting control method, ginseng
According to attached drawing 2, this method includes：
Step S10, opens the baking function and/or hot wind function of micro-wave oven, and control micro-wave oven heats work(with default starting
Rate treats thawed foodstuff and thaws；
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.
Barbecue tube can be set in the heating chamber of micro-wave oven, hot blast pipe or microwave oven heating cavity while barbecue tube either is set
And hot blast pipe, barbecue tube are generally located on the top of microwave oven heating cavity, because being carried out in course of defrosting to food, the bottom of food
The water of heating and melting is assembled in portion, water to the absorption of microwave heating faster, temperature promoted faster, lead to the bottom of food in course of defrosting
Portion's temperature is generally greater than head temperature, therefore barbecue tube is set at the top of heating chamber, is realized a degree of temperature-compensating, is not allowed
Easily lead to hot-spot or overdone in course of defrosting.Hot blast pipe then generally selects back hot blast pipe, i.e. hot blast pipe to be generally located on
The back (back is heating chamber enabling side opposite side) of microwave oven heating cavity, hot blast pipe can be relatively easily from micro-wave oven
Back, which is arranged air inlet and realizes, enters the wind, and avoids that air inlet is arranged and causes in air inlet leakage to micro-wave oven at the top of micro-wave oven
The problem of portion, and back hot blast pipe may advantageously facilitate the hot air circulation in microwave oven heating cavity, makes heating in heating chamber more
Add uniformly.
It is waiting for that thawed foodstuff is put into the initial stage of microwave oven heating cavity, is starting the baking function and/or hot wind function of micro-wave oven
It treats thawed foodstuff quickly heat and thaw, while the microwave source of micro-wave oven treats defrosting food with default starting heating power
Object thaws.Certainly, it supports the barbecue tube of baking function and supports the hot blast pipe of hot wind function that can individually select or select simultaneously
With.In general, single barbecue tube or the input power of single hot blast pipe are 1800W (conventional value can be increased or reduced suitably),
To prevent complete machine power excessive, usual barbecue tube and hot blast pipe alternative use；If the power summation of barbecue tube and hot blast pipe
No more than 1800W, barbecue tube and hot blast pipe can also be applied in combination.
The baking function and/or hot wind function of micro-wave oven are being opened, and is controlling micro-wave oven with default starting heating power pair
It waits for that thawed foodstuff thaws, is equivalent to micro-wave oven to preset big fire heating power.In a particular embodiment, in micro-wave oven with pre-
If big fire heating power is heated, micro-wave oven should be less than 400W using frequency conversion low-power.Most due to electric power cord for microwave oven
Big input current is usually 10A, and when rated voltage is 220V, then maximal input is 2200W, removes the work(of barbecue or hot wind
Rate 1800W, magnetron maximal input are 400W, are just met for requiring.The minimum continuous work power of micro-wave oven frequency converter
For 400W, break-make control is then carried out based on 400W in proportion less than 400W, it is assumed that certain grade of firepower of micro-wave oven is 100W, then uses
400W power leads to 15min then disconnected 45min.
Step S20, in micro-wave oven treats thawed foodstuff progress course of defrosting, detection waits for the real-time temperature on thawed foodstuff surface
Degree；When real time temperature be more than the first preset temperature, close the baking function and/or hot wind function of micro-wave oven；
In embodiments of the present invention, one or more temperature sensors can be set in the heating chamber of micro-wave oven, such as infrared
Sensor.Temperature sensor shell may be disposed at the top area of heating chamber, and temperature sensor carries food to heating chamber bottom
Vessel region carries out temperature detection, and when thawed foodstuff is put into vessel, thawed foodstuff is waited in temperature sensor detection vessel
The real time temperature of top surface.For another example temperature sensor shell is set to heating chamber vessel back side, and temperature sensor is to vessel bottom
Wait for that the bottom temp of thawed foodstuff is detected, wait for thawed foodstuff bottom temp be real time temperature.
When micro-wave oven starts to heat the band thawed foodstuff in heating chamber, start-up temperature sensor waits solving to detect
Freeze the real time temperature 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
Object temperature is relatively low and starts intelligent defrosting function automatically, starts to execute microwave oven defrosting control method of the present invention, starts detection and waits for
The real time temperature of thawed foodstuff.
In general, the freezing rate for being placed on internal water the food (such as meat) of -18 DEG C of freezings of refrigerator is about 90%, i.e.,
In addition to most water becomes ice crystal in the food freezed, still there is the water of fraction not freeze.And the dielectric loss factor of water is remote
More than the dielectric loss factor of ice, the dielectric loss factor of -13 DEG C of ice is for the dielectric loss factor of 0.0028,25 DEG C of ice
12.3, i.e. water is significantly larger than absorption of the ice to microwave to microwave absorption.Therefore, when thawed foodstuff when starting to thaw, if only selecting
With microwave heating, then wait for that the defrosting of thawed foodstuff is less efficient.In addition, the specific heat capacity of ice is the half of water, the specific heat capacity of water is
4.2kJ/ (kg* DEG C), ice are 2.1kJ/ (kg* DEG C)；The thermal conductivity of water is 0.582W/ (m*k), and the thermal conductivity of ice is
2.326W/ (m*k), about the 4 of water times, therefore the heat transfer effect of ice is preferable.In conclusion when ice crystal is more in the human body,
Barbecue or the high-power heating of hot wind are selected, makes to wait for thawed foodstuff (such as meat) interior ice crystal by thermal convection current, heat radiation and thermal diffusion
Fast melt, while assisting heating the water not freezed with low power microwave, make Wen Sheng, thawing rate faster.
When real time temperature is more than the first preset temperature, the baking function and/or hot wind function of micro-wave oven are closed, such as based on
Infrared sensor carry out food temperature detection, when detect wait for thawed foodstuff surface real time temperature be higher than the first preset temperature
(such as -1 DEG C) waits for that ice crystal largely melts inside thawed foodstuff, causes to wait for thawed foodstuff to prevent microwave from focusing at this time
Hot-spot closes the baking function and hot wind function of micro-wave oven.
Step S30, according to real time temperature, adjustment micro-wave oven treats the heating power that thawed foodstuff thaws；
In detecting micro-wave oven after the real time temperature of thawed foodstuff, the heating of micro-wave oven is adjusted according to real time temperature
Power, wherein real time temperature are higher, show to wait for that the surface temperature of thawed foodstuff is higher, wait for that thawed foodstuff surface is more susceptible to office
Portion's temperature is excessively high and deeply worried, and therefore, the heating power that corresponding micro-wave oven treats thawed foodstuff output is bigger.
It is more than the first preset temperature in detection real time temperature, closes after baking function and the hot wind function of micro-wave oven, it can
Control micro-wave oven treats thawed foodstuff with default small fire heating power and carries out microwave heating, and the detection of real time temperature can be based on infrared
Sensor is realized.When the setting of micro-wave oven frequency converter firepower remains default small fire heating power, due to waiting for inside thawed foodstuff
Ice crystal largely melts, and the Free water of precipitation is more and more, and microwave heating efficiency is much larger than barbecue and hot wind at this time, in order to save
Can, barbecue and hot wind function are closed, is only heated using microwave.Since default small fire heating power heating process uses 400W
Break-make controls, i.e., heating a period of time, then thermal diffusion for a period of time, was conducive to improve hot-spot problem in this way.Due to using
Frequency conversion low-power and infrared measurement of temperature, therefore course of defrosting carries out turn-over without treating thawed foodstuff, solves in micro-wave oven
User waits for the very big pain spot of Attended Operation during thawed foodstuff.
Step S40 stops the defrosting that micro-wave oven treats thawed foodstuff when real time temperature is more than default defrosting maximum.
Thawed foodstuff is waited in by micro-wave oven heating process, for example, wait for thawed foodstuff be meat, thaw the starting stage, by
In containing a large amount of ice crystal and minimal amount of water in meat body, since the thermal conductivity of ice is about 4 times of water, the heat of ice transmits effect
Fruit is preferable, and the dielectric loss factor of water is much larger than the dielectric loss factor of ice, therefore, at the microwave stove heat initial stage of meat,
A small amount of water in mainly heating in class, leading to heat transfer after water heating makes the ice of meat gradually melt.Since the heat of ice is transmitted
Effect is preferable, and the inside and outside heat transfer of meat is very fast, and the ice inside meat can quickly absorb outside meat because of microwave heating institute
The heat of absorption, keep meat external temperature will not excessively rapid growth, unit interval temperature variation it is smaller.When the ice in meat is big
After being partly or entirely converted to water, without absorbing a large amount of latent heat, the inside and outside temperature of meat remains basically stable, at this moment micro-wave oven pair
Meat continues to heat, and the external temperature of meat can rise rapidly, and the real time temperature of temperature sensor detection at this time quickly increases.Cause
This shows that the ice in meat melts substantially, meat inside and outside heat transfer rate when real time temperature is more than default defrosting maximum
It reduces, meat defrosting is basically completed, and is stopped micro-wave oven at this time and is heated to the defrosting of meat.Similarly, other kinds of to wait the food that thaws
Object and meat defrosting process are essentially identical, do not do tired state.
In addition, it is contemplated that uniformity may cause to wait for that thawed foodstuff internal difference in temperature is 10 DEG C, therefore default defrosting maximum
It preferably 15 DEG C, waits for that the thawed foodstuff internal temperature highest temperature will be less than 25 DEG C in this way, ensure that and wait for that thawed foodstuff will not be by part
It heats ripe.
In the present embodiment, by the baking function for micro-wave oven of after micro-wave oven is put into and waits for thawed foodstuff, first shooting and/
Or hot wind function, control micro-wave oven treat thawed foodstuff with default starting heating power and thaw；Then it is treated in micro-wave oven
Thawed foodstuff carries out in course of defrosting, and detection waits for the real time temperature of thawed foodstuff；When real time temperature is more than the first preset temperature, pass
Close the baking function and/or hot wind function of micro-wave oven；Further according to real time temperature, adjustment micro-wave oven treats thawed foodstuff and thaws
Heating power, wherein real time temperature is higher, and the heating power that micro-wave oven treats thawed foodstuff is smaller；It is finally big in real time temperature
When default defrosting maximum, stop the defrosting that micro-wave oven treats thawed foodstuff；Ice crystal inside thawed foodstuff is being waited for realize
It when more, real time temperature is far below zero degree, with baking function and/hot wind function, is combined with microwave heating, treats thawed foodstuff progress
Quick ice-breaking and defrosting wait for the reality of thawed foodstuff after largely melting after absorbing a large amount of latent heat after ice crystal inside thawed foodstuff
Shi Wendu is quickly increased, and when real time temperature is more than the first preset temperature, shows the internal-external temperature difference that thawed foodstuff is waited for even if consideration,
Wait for the inside and outside temperature of thawed foodstuff it is also higher, it is basic defrosting complete, so when stop micro-wave oven treating thawed foodstuff plus
Heat and defrosting, to avoid waiting for thawed foodstuff hot-spot and become ripe, carried out to food in course of defrosting without user etc.
It waits for manual turn-over, greatly reduces the Operating Complexity of defreezing by microwave oven.
Further, in another embodiment of microwave oven defrosting control method of the present invention, step S30 includes：
Step S31 is dynamically determined real-time where real time temperature by real time temperature compared with preset temperature range list
Heated in real-time power corresponding to temperature range and the real time temperature section；
Step S32, dynamic control micro-wave oven treat thawed foodstuff with heated in real-time power 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 real time temperature section according to the numerical values recited of real time temperature
Belong to the numberical range of which temperature range, that is, is dynamically determined the real time temperature section where different moments real time temperature, and base
In the mapping relations of the temperature range and heating power that are previously set, further determines that each real time temperature section is corresponding and add in real time
Thermal power.To which in the heating process that micro-wave oven treats thawed foodstuff, dynamic control micro-wave oven is under different moments, with real-time
The corresponding heated in real-time power in real time temperature section treats thawed foodstuff and thaws where temperature, to accurate, independent
Temperature range realizes that the segmentation to real time temperature divides, to realize the segmentation to heating power under micro-wave oven difference real time temperature
Control avoids waiting for that thawed foodstuff local temperature due to micro-wave oven heating power is excessive is excessive, locally burns or becomes ripe.
Optionally, real time temperature section and the real time temperature section where real time temperature are dynamically determined in step S31
The step of corresponding heated in real-time power, may include：
When the real time temperature section where real time temperature is more than the first preset temperature, less than the temperature of default defrosting maximum
When spending section, adjustment heated in real-time power is default small fire heating power, wherein the first -1 DEG C of preset temperature value, presets and thaw
15 DEG C of maximum value.
That is, without this microwave stove heat gear of the default small fire heating power of setting, need to only thawed foodstuff be being waited for
Real time temperature be more than the first preset temperature (as -1 DEG C) and less than or equal to default defrosting maximum (such as 15 DEG C), adjust micro-wave oven
Heated in real-time power be that default small fire heating power further enhances thawing food in microwave oven without undergoing moderate heat heating
Heating uniformity.
Based on above-mentioned explanation content, the defreezing by microwave oven intelligent control of the present embodiment includes mainly the big fire heating period and small
The fiery heating period.
In the small fire heating period thawed foodstuff is waited for due to waiting for that the real time temperature of thawed foodstuff has risen to phase transition temperature
Middle majority ice crystal progresses into solid-liquid phase change state, waits for that thawed foodstuff inside and outside temperature difference and heat transference efficiency further decrease,
And wait for that defrosting microwave focuses and leads to homogeneous heating sex chromosome mosaicism, need to turn the heating power of micro-wave oven down, i.e., when real-time in order to prevent
