Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Fig. 1 is the structural representation of a kind of thawing apparatus in one embodiment of the invention, as it is shown in figure 1, include: housing 3,
First battery lead plate the 1, second battery lead plate 2 and high frequency electric source 8.
Wherein, described first battery lead plate 1 is arranged at the top of described housing 3 inwall, and described second battery lead plate 2 is arranged at institute
State the bottom of housing 3 inwall, and described first battery lead plate 1 and described second battery lead plate 2 respectively with the two ends of described high frequency electric source 8
Connect.
When described high frequency electric source 8 works, between described first battery lead plate 1 and described second battery lead plate 2, produce high-frequency alternating
Electric field, acts on and is defrosted food generating frequency electromagnetic waves.
Specifically, the defrosting principle of frequency electromagnetic waves is to utilize the dielectric property of material to carry out heating to thaw.Quilt
Polar molecule (referred to as dipole) in defrosting food material is making mixed and disorderly random motion, and such as water is exactly polar molecule,
Then as in figure 2 it is shown, when being not powered on, polar molecule points to any direction；And when switch Guan Bi, when being i.e. in electric field, pole
Property molecule will rearrange, and one end of positively charged is towards negative pole, and electronegative one end is towards positive pole.If change direction of an electric field, then
The orientation of polar molecule changes the most therewith.If high-frequency electric field the most alternately changes direction, then polar molecule is also along with making rapidly
Swing.Due to the interaction between the warm-up movement of molecule and adjacent molecule, the rule that polar molecule changes with direction of an electric field and makees
Then swing and will be interfered and hinder, i.e. create the effect of similar friction, make molecule obtain energy, and show in the form of heat
Out, the temperature showing as being defrosted food material raises, thus thaws.
It should be noted that the frequency of extra electric field is the highest, the swing of molecule is the fastest, and the heat of generation is the most.Outward
The electric field intensity of added electric field is the biggest, and the amplitude of molecule is the biggest, and the heat of generation is the most.Material is in high frequency waves and microwave field
The size of produced heat is also relevant with the kind of material and composition, i.e. dielectric constant and angle of loss with material just cuts with
Close.
As can be seen here, the thawing apparatus in the present embodiment is provided with the first battery lead plate put and the second battery lead plate relatively,
And the two ends of high frequency electric source are connected with the first battery lead plate and the second battery lead plate respectively, and during high frequency electric source work, at the first electricity
Form high-frequency electric field between pole plate and the second battery lead plate, thus generate frequency electromagnetic waves and act on and be defrosted food so that be whole
The molecule of food is all acted on by frequency electromagnetic waves so that it is the polarity generation high frequency time change of polar molecule, so that being solved
Jelly food is the most heated and thaws.As can be seen here, the thawing apparatus simple in construction in the present embodiment, and frequency electromagnetic waves
Thawing rate is fast, thaw uniformly and nutritive loss is little.
Further, as it is shown in figure 1, described thawing apparatus also includes: be arranged in the first battery lead plate 1 and described housing 3
The first insulating barrier 4 between wall；It is arranged at the second insulating barrier 5 between described second battery lead plate 2 and described housing 3 inwall；If
It is placed in described first battery lead plate 1 the 3rd insulating barrier 6 towards described second battery lead plate 2 side；It is arranged at described second battery lead plate 2
The 4th insulating barrier 7 towards described first battery lead plate 1 side.
So, the first battery lead plate 1 is isolated by the first insulating barrier 4 with housing 3, and the second insulating barrier 5 is by the second battery lead plate 2 and shell
Body 3 is isolated.And the first battery lead plate 1 and the second battery lead plate 2 deviate from the side of housing 3 be respectively arranged with the 3rd insulating barrier 6 and
4th insulating barrier 7, will be defrosted food and be placed directly within the 4th insulating barrier 7, so, prevent being defrosted food directly electric with second
Pole plate 2 directly contacts, and prevents user from directly connecing with the first battery lead plate 1 or the second battery lead plate 2 during using thawing apparatus
Touch, add the safety in utilization of thawing apparatus.
Fig. 3 is a kind of refrigerator in another embodiment of the present invention, and this refrigerator includes: such as any one thawing apparatus above-mentioned.
Specifically, in described thawing apparatus is arranged at the defrosting room 300 of described refrigerator.
So, this refrigerator can be that the food that is defrosted being positioned over defrosting room enters by the frequency electromagnetic waves that thawing apparatus produces
Row thaws.And the advantage that frequency electromagnetic waves thaws includes:
(1) temperature of charge after thawing is uniformly, bigger material also can thaw.
The frequency electromagnetic waves that the present embodiment uses is at 1-50MHz, and preferably high-frequency range is at 10-20MHz scope, the frequency of microwave
Rate scope is typically at (300MHz～300GHz).Although microwave frequency is higher than microwave frequency, but the defrosting effect of high frequency waves is more
Good, the temperature of charge uniformly bigger material after high frequency waves thaw also can thaw.
Table one is water and ice act under high frequency waves and microwave after mass loss coefficient.Table two be beef at high frequency waves and
The degree of depth that partly declines under microwave.Electromagnetic wave through food surface internally irradiate time, strengthen with its penetration depth, the energy of electromagnetic wave
Decay rapidly, the depth capacity penetrated by electromagnetic wave is referred to as penetration depth or fading depth.Fading depth and the frequency of electromagnetic wave
Rate is inversely proportional to.By table one and table two it can be seen that when microwave heating thaws, the degree of depth that partly declines due to it is less, the surface of material
Temperature and central temperature difference are big, and material surface local solution is frozen, and ice changes into water, due to water and ice loss coefficient difference very
Greatly, many at this microwave energy partially absorbed, it is easy for causing the superheating phenomenon even ripening of this part.Add vice versa for high frequency waves
Pyrolysis is frozen, and its degree of depth degree of depth that partly declines much larger than microwave that partly declines, surface temperature and central temperature difference are little, the loss system of water and ice
Number difference is the least, and temperature distribution uniform during defrosting does not haves superheating phenomenon.So high frequency wave energy material big to thickness solves
Freeze, and the quality after defrosting is higher.
Table one water and the loss coefficient of ice
| High frequency waves (13.56MHZ) | Microwave (915MHZ) | |
| Ice (-15 DEG C) | 0.07 | 0.06 |
| Water (15 DEG C) | 0.63 | 2.7 |
| Loss coefficient ratio | About 9 times | About 45 times |
The degree of depth that partly declines of table two beef
| High frequency waves (13.56MHZ) | Microwave (915MHZ) | The ratio of the degree of depth that partly declines | |
| Freezing beef (-15 DEG C) | 61cm | 12cm | About 5 times |
| Raw beef (15 DEG C) | 26cm | 3cm | About 806 times |
(2) thawing rate is fast
Because the frequency of high frequency waves is less than the frequency of microwave, fading depth is inversely proportional to the frequency of electromagnetic wave, and research shows
The penetration depth of high frequency waves is about 5 times 14 times of microwave, and therefore the speed of high frequency defrosting is faster, owing to thawing rate the most just subtracts
Lack the probability that microorganism is polluted.
(3) high frequency defrosting nutritive loss is few
In high frequency waves course of defrosting, drip loss is relatively low, and this technology can make frozen food molten quickly through maximum ice crystal
Ungirding, drip loss is little, even without.
(4) ice milk thaws dual-purpose, energy-conservation, save space.
Energy-conservation: when microwave thawing, freeze somewhere, product surface ice-out Cheng Shui, the temperature at this will be made to raise rapidly, and
When high frequency thaws, with freezing the rising of product temperature, quickly, high frequency voltage is gradually difficult to act on and freezes product, test in dielectric constant increase
Showing that about-5 DEG C thawing rates reduce, when more than-2 to-3 DEG C, high-frequency induction loses thaw effects, i.e. high-frequency induction can be certainly
The dynamic terminal controlling to thaw, defrosting outlet temperature now is consistent with the ice milk district temperature of refrigerator, from refrigerator angle analysis ratio
More energy-conservation.Ice milk thaws dual-purpose: when the use of defrosting district is not done in this interval, this interval can use as ice milk interval, deposit
Need not the food preserved for a long time.Owing to high frequency thaws, different with other defrosting, the high frequency defrosting temperature to defrosting district
Degree change impact is little, therefore, in the case of ice milk food itself has been deposited in this district, it is also possible to frozen food is put into defrosting
District, starts high frequency and thaws, and makes to be defrosted food defrosting to-5 DEG C～-1 DEG C, consistent with the holding of the temperature of original ice milk food.
In an alternate embodiment of the present invention where, as shown in Figure 4, the thawing apparatus in described refrigerator includes: housing 3,
First battery lead plate the 1, second battery lead plate the 2, first insulating barrier the 4, second insulating barrier the 5, the 3rd insulating barrier 6 and the 4th insulating barrier 7.First
First battery lead plate 1 and the second battery lead plate 2 are kept apart by insulating barrier 4 and the second insulating barrier 5 with refrigerator main body, and are defrosted food and put
On the 4th insulating barrier 7.During high frequency electric source work, frequency electromagnetic waves acts on and is defrosted food, makes the molecule of whole food all
Acted on by high frequency waves so that it is the change of the polarity generation high frequency time of polar molecule, so that being defrosted food inside and outside quilt simultaneously
Heating is thawed.
Further, as shown in Figure 4, this refrigerator also includes: defrosting room door trip 9 and defrosting activate switch 10.Described solution
The high frequency electric source frozen in device includes: alternating current power supply 81 and high frequency generator 82.
Correspondingly, the two ends of described high frequency generator 82 connect with described first battery lead plate 1 and described second battery lead plate 2 respectively
Connecing, the first end of described high frequency generator 82 is connected by the first end of described defrosting room door trip 9 with described alternating current power supply 81,
Second end of described high frequency generator 82 is connected with the second end of described alternating current power supply 81 by the described unlatching switch 10 that thaws.
So, when the defrosting room door trip 9 of described refrigerator closes and the unlatching switch 10 that thaws closes, alternating current power supply 81 is
High frequency generator 82 provides power supply, then high frequency generator 82 is started working, so the first battery lead plate 1 and the second battery lead plate 2 it
Between produce high-frequency alternating field, act on and be defrosted food generating frequency electromagnetic waves.
Further, in an alternate embodiment of the present invention where, as shown in Figure 4, described refrigerator also includes: infrared temperature
Sensor 11.
Wherein, described infrared temperature sensor 11 is fixed on the side of housing 3 inwall of described thawing apparatus, is used for detecting
The described temperature being defrosted food.
It should be noted that fixed form the present embodiment of infrared temperature sensor 11 uses the mode of relatively hinge, when
So also can take other such as modes such as hook, buckles, as long as reaching fixing purpose, this is not limited by the present embodiment
System.
In an alternate embodiment of the present invention where, described refrigerator includes: direct-cooled vaporizer.
Wherein, described direct-cooled vaporizer is attached between postnotum and the foaming layer of described thawing apparatus；
Correspondingly, described thawing apparatus also includes: temperature sensor.
Or, in an alternate embodiment of the present invention where, described refrigerator also includes: fan.
Correspondingly, as shown in Figure 4, described thawing apparatus also includes: the air inlet 12 being arranged on housing and air outlet 13,
And temperature sensor.
As can be seen here, the defrosting room of this refrigerator, when being in thawed state, need to make this defrosting room temperature automatic control arrive
In default temperature range (such as-5 DEG C～-1 DEG C).The temperature in this interval controls can be by air-cooled or direct-cooled refrigeration side
Formula realizes.When using direct-cooled mode, direct-cooled vaporizer is attached between defrosting room postnotum and foaming layer, and is close to back
Plate；When using air-cooled refrigeration modes, as shown in Figure 4, on the thawing apparatus top of defrosting room, the rightest back upper place arranges air intake
Mouth 12, in the bottom in high frequency defrosting district, preferably bottom, left front arranges return air inlet 13, and this interval arranges that temperature sensor is (in Fig. 4
Not shown), to control temperature in default temperature range (such as-5 DEG C～-1 DEG C), air cooling way is also beneficial to thawing rate
Further speed up.
Further, described refrigerator also includes: is arranged at the thawing time of control panel and arranges button and defrosting weight sets
Put button.
If user can the most directly determine thawing time, then user can arrange key-press input defrosting by thawing time
Time.For example, as it is shown on figure 3, arrange set of time button on the control panel, be respectively minute and 10 seconds setting press
Key, minute arranges button often by next time, accumulates one minute, and within 10 seconds, button is often by next time, cumulative 10 seconds.According to
Minute and the number of times that is pressed for 10 seconds determine thawing time.A such as minute button is pressed 2 times, and 10 seconds buttons are pressed 3
Secondary, then thawing time be 2 points 30 seconds.The time of set of time process and course of defrosting dynamically shows on the display of control panel
Show.
If user cannot determine thawing time, need to determine thawing time according to weight, then can be arranged by defrosting weight
Key-press input is defrosted the weight of food.For example, as shown in Figure 6, set of time button it is provided with on the control panel, respectively
Arranging button for kg and 0.1kg, kg arranges button often by next time, accumulates 1kg, 0.1kg button often by next time, cumulative
0.1kg.The number of times being pressed according to kg button and 0.1kg button determines and is defrosted food weight.Such as kg button is pressed 2
Secondary, 0.1kg button is pressed 3 times, then being defrosted food weight is 2.3kg.The control software of refrigerator inquires about weight according to weight
Time correspondence table, to determine the high frequency generator working time.Weight setting up procedure and course of defrosting are at the display of control panel
Upper display.
Fig. 7 is that a kind of flow process such as the unfreezing control method of any one refrigerator above-mentioned that one embodiment of the invention provides is shown
It is intended to, as it is shown in fig. 7, the method comprises the steps:
S1: when the defrosting room door trip of described refrigerator closes and the unlatching switch that thaws closes, high frequency generator works,
Produce high-frequency alternating field between first battery lead plate and the second battery lead plate, act on and be defrosted food generating frequency electromagnetic waves.
S2: be defrosted described in detecting food reach preset thaw point or reach preset thawing time time, by high frequency
Defrosting patten transformation is ice milk pattern, and disconnects the described unlatching switch that thaws.
Specifically, the infrared temperature sensor by being arranged in refrigerator defrosting room detects the temperature being defrosted food
Degree.
As can be seen here, in the present embodiment, defrosting control mode includes two kinds, and one is to control according to the temperature being defrosted food,
Two is to control according to the time thawed.In two kinds of control modes, for improving safety in utilization, the defrosting room door trip letter of refrigerator
Number it is connected in the control loop of high frequency generator, when opening the door in defrosting district, cuts off the input electricity of high frequency generator, thus
High frequency generator is made not work.When the door in defrosting district is closed, high frequency generator just works.
So, the unfreezing control method in the present embodiment, because its defrosting outlet temperature is in ice milk district, therefore this district can use
Thaw, it is also possible to the short-term as some food is stored.Defrosting room in the present embodiment is in course of defrosting, owing to temperature becomes
Changing little, even if being the defrosting work phase, nor affecting on the storage of short-term ice milk food.
In an alternate embodiment of the present invention where, described method also includes:
Receive user, by thawing time, is set as described default thawing time the time of key-press input；Or,
Receive user and the food weight that is defrosted of key-press input is set by defrosting weight, and according to the default weight time
Corresponding table lookup is defrosted thawing time corresponding to food weight as described default thawing time described in going out.
In order to be illustrated more clearly that technical scheme, illustrate above-mentioned below by more specifically embodiment
Anticipate the unfreezing control method of a kind of refrigerator.
Fig. 8 is the unfreezing control method ground schematic flow sheet of any one refrigerator above-mentioned in another embodiment of the present invention,
As shown in Figure 8, the method includes:
S801: whether detection refrigerator defrosting room door trip closes, if then going to step S802.Otherwise go to step
S806；
S802: detection is thawed and is opened whether switch closes, if then going to step S803, otherwise goes to step S806；
S803: high frequency generator works；
Specifically, when the defrosting room door trip of described refrigerator closes and the unlatching switch that thaws closes, alternating current power supply is
High frequency generator provides power supply, then high frequency generator is started working, and then produces between the first battery lead plate and the second battery lead plate
High-frequency alternating field, acts on and is defrosted food generating frequency electromagnetic waves.
S804: detection is defrosted whether food temperature reaches to preset thaw point, if then going to step S805, otherwise turns
To step S803；
S805: be ice milk pattern by the defrosting patten transformation of defrosting room；
