Specific embodiment
To facilitate the understanding of the present invention, a more comprehensive description of the invention is given in the following sections with reference to the relevant attached drawings.In attached drawing
Give presently preferred embodiments of the present invention.But the invention can be realized in many different forms, however it is not limited to this paper institute
The embodiment of description.On the contrary, purpose of providing these embodiments is keeps the understanding to the disclosure more thorough
Comprehensively.
As shown in Figure 1A, in one embodiment, a kind of anti-dewdrop method for heating and controlling is provided, comprising:
Step 102, ambient humidity is detected.
In the present embodiment, the ambient humidity of this step detection predeterminable area, specifically, detection turnover beam of refrigerator surface
Humidity, flip beam surface moisture is high, then is easy to cause on flip beam and condenses droplet.One embodiment is to pass through humidity sensor
Detect the humidity on flip beam surface.
Step 104, corresponding first humidity section is obtained according to the ambient humidity.
Specifically, detection gets ambient humidity, and obtains the corresponding humidity section of the ambient humidity, and humidity is divided into
Multiple humidity sections, humidity section are the range of a humidity, and each humidity section corresponds to multiple continuous in the humidity range
Humidity value for example, humidity section is 60%~70%, or is 50%~60%, in this step, according to the environmental wet of detection
Degree, obtaining current humidity section is the first humidity section.
Step 106, it is worked according to the first humidity range restraint heater with corresponding first operation ratio.
Specifically, operation ratio is the ratio of runing time and a cycle of operation, and heater is worked with a certain operation ratio, example
Such as, which is 50%, then within a cycle of operation, the time of operation and the ratio of the cycle of operation are the heater
50%, and at runtime between it is outer, then heater be in free time, and after a cycle of operation, then into next fortune
The row period.Specifically, the operation of heater is that heater work is heated.
In the present embodiment, the corresponding operation ratio in each humidity section, the corresponding medial humidity in humidity section is higher, then corresponds to
Operation ratio it is higher, specifically, in humidity section the average value of multiple humidity be the corresponding medial humidity in humidity section, or
Person, maximum humidity and the average value of the smallest humidity are the corresponding medial humidity in the humidity section in humidity section；At other
In embodiment, the humidity in humidity section in middle position is higher, then corresponding operation ratio is higher.
In this step, worked according to the first humidity range restraint heater of acquisition with corresponding first operation ratio, so that
Heater works in suitable operation ratio, eliminates dewdrop better effect, and more energy saving.
Step 108, when the ambient humidity is changed to the second humidity section by first humidity section, described in detection
Ambient humidity maintains the time span in second humidity section.
Specifically, when ambient humidity changes, ambient humidity will be changed to another humidity section by a certain humidity section, such as
When current environment humidity is in the critical range in a certain humidity section, even if varying less for ambient humidity generation, also leads to
It is corresponding to different humidity sections, in the present embodiment, ambient humidity by being changed in the second humidity section in the first humidity section,
The time span that ambient humidity is changed to the second humidity section and maintains the second humidity section is then detected, and then judges environmental wet
Whether degree is to be changed to another humidity section stable.
Step 110, when the time span be greater than the first preset time, then control heater with second humidity province
Between the work of corresponding second operation ratio.
Specifically, when time span is greater than the first preset time, show that ambient humidity is changed in the second humidity section
Time it is longer, then ambient humidity is relatively stable, not changing frequently in two humidity sections, then adjusts the fortune of heater
Row rate is extremely corresponding with the second humidity section, and control heater is worked with the second operation ratio, it should be understood that due to ambient humidity
It changes, and relatively stable, in order to enable eliminating dewdrop better effect, it should so that heater is with operation corresponding with humidity
Therefore rate work is adjusted the operation ratio of heater and is worked with operation ratio adjusted control heater in the present embodiment, so that
The heater to work under the operation ratio is more suitable for the ambient humidity after variation, eliminates dewdrop better effect, and more save
Energy；On the other hand, due to adjustment heater operation ratio be it is relatively stable in ambient humidity, maintain a humidity province for a long time
In after, can effectively avoid heater strip from frequently adjusting operation ratio in a short time, effectively avoid heating wire works abnormal with
And control program exception is avoided, effectively increase the service life of heater strip.
As shown in Figure 1B, in one embodiment, after step 108 further include:
Step 109, when the time span be less than or equal to the first preset time, then control heater maintain with first fortune
The work of row rate.
Specifically, when time span is less than or equal to the first preset time, then ambient humidity is changed by the first humidity section
To the second humidity section, it is changed to the first humidity section again in the first preset time, alternatively, ambient humidity is by the first humidity
After section is changed to the second humidity section, other humidity sections are changed in the first preset time, and be changed to other humidity
It is changed to the first humidity section after in section again in the first preset time, then shows that ambient humidity frequently becomes in a short time
Change, cannot maintain for a long time in a humidity section, it is more unstable, therefore, in this step, it is less than or waits in time span
When the first preset time, control heater maintains to change frequently in a short time with the work of the first operation ratio in ambient humidity
When variation, the operation ratio of heater remains unchanged, and effectively heater strip can be avoided frequently to adjust operation ratio in a short time, had
Effect avoids heating wire works exception and avoids control program exception, effectively increases the service life of heater strip.
As shown in Figure 1 C, in one embodiment, step 110 includes:
Step 110a, when the time span is greater than the first preset time, the humidity value in the second humidity section of comparison and institute
State the humidity value in the first humidity section.
It is when maintained in a humidity section in a longer period of time, then right after ambient humidity variation in the present embodiment
Than the humidity value in the second humidity section and the humidity value in first humidity section, specifically, the second humidity province of comparison can be
Between humidity mean value and first humidity section humidity mean value, humidity mean value be the corresponding multiple humidity values in the humidity section
Average value；It is also possible to compare the middle position humidity value in the second humidity section and the middle position humidity value in first humidity section；
It is also possible to compare any humidity value in the second humidity section and any humidity value in first humidity section.
Step 110b, when second humidity section humidity value be higher than first humidity section humidity value, then control
The heater is made to continue working in the second preset time.
Specifically, according to the height of humidity in the present embodiment, humidity section is divided into multi gear, the humidity section of low gear is put down
Equal humidity is low, and the medial humidity in high-grade humidity section is high, and whole humidity values in high-grade humidity section are all larger than low gear
Whole humidity values in humidity section.The humidity value in humidity section is higher than the humidity value in the first humidity section, then shows environmental wet
Degree is toward high-grade humidity section direction change, i.e. ambient humidity is got higher, and ambient humidity is got higher, then means more easily to produce
Raw dewdrop, and dewdrop quantity is also more, in order to rapidly remove dewdrop under higher ambient humidity, heater is needed not to be spaced
Ground works quickly to increase temperature, and in the present embodiment, heater continues working in the second preset time, i.e., default second
In time, heater does not have free time, by the continuous heating of heater to reach speed heat effect, so that in higher environment
Dewdrop can be removed rapidly under humidity.
Step 110c controls heater after the second preset time with the second fortune corresponding with second humidity section
The work of row rate.
Specifically, before heater continuous heating, heater is worked with the first operation ratio, after heater continuous heating,
Heater is worked with the second operation ratio.Due to the heating lasting by heater, in the raised situation of ambient humidity, dewdrop is
It is efficiently removed, therefore, need to only maintain higher operation ratio at this time can effectively prevent condensing dewdrop on flip beam, therefore,
In heater after the continuous heating of the second preset time, control heater is worked with the second operation ratio.
Referring again to Fig. 1 C, in one embodiment, after step 110a further include:
Step 110d, when second humidity section humidity value be lower than first humidity section humidity value, then control
Heater processed is worked with the second operation ratio corresponding with second humidity section.
Specifically, the humidity value in the second humidity section is lower than the humidity value in the first humidity section, then shows that ambient humidity is
Toward low-grade humidity section direction change, i.e. ambient humidity is lower, and ambient humidity is lower, then heater is not necessarily to continuous heating,
With more energy-efficient operation ratio work.In the present embodiment, the humidity value in the second humidity section is wet lower than the first humidity section
Angle value, correspondingly, the second operation ratio are lower than the first operation ratio, in this way, heater is worked with lower operation ratio, it is more energy saving.
In one embodiment, second preset time and the humidity mean value in second humidity section and described first
Difference between the humidity mean value in humidity section is positively correlated functional relation.Specifically, second preset time is according to
Difference between the humidity mean value in the second humidity section and the humidity mean value in first humidity section and adjust, described second is wet
The difference spent between the humidity mean value in section and the humidity mean value in first humidity section is bigger, and second preset time is got over
Greatly.
In the present embodiment, the raised ratio of length and ambient humidity of the second preset time is in direct ratio, specifically, works as ring
Border humidity rises more, then humidity variation is bigger, dewdrop is more easy to produce, therefore, when heater needs continuous heating longer
Between, dewdrop could be removed.Therefore, in the present embodiment, the second preset time is according to the humidity mean value and first in the second humidity section
Difference between the humidity mean value in humidity section and adjust, it is preferable that the humidity mean value and the first humidity province in the second humidity section
Between humidity mean value between difference it is bigger, the second preset time is bigger.When the humidity mean value in the second humidity section and first wet
The the difference spent between the humidity mean value in section the big, and it is more to show that humidity increases, then the continuous heating time of heater is longer,
In this way, heater can quickly, efficiently remove dewdrop under higher ambient humidity.
Here is the specific embodiment of an anti-dewdrop method for heating and controlling:
In the present embodiment, as shown in the table, humidity section is divided into five gears, corresponds to five operation ratios of heater,
The corresponding operation ratio in the humidity section of i.e. one gear, gear is higher, and the humidity value in humidity section is higher；Gear is higher,
Corresponding operation ratio is higher.
For example, humidity section is gear a period of time, corresponding humidity is 40%~50%, i.e. the humidity section of gear one includes
Greater than 40%, humidity value less than or equal to 50%, the humidity section of gear two includes to be greater than 50%, less than or equal to 60%
Humidity value, in this way, all humidity values of gear two are all larger than all humidity values of gear one, the institute in the humidity section of high tap position
There is humidity value to be all larger than all humidity values in the humidity section of low-grade location.
With 20 seconds for a cycle of operation in the present embodiment, when heater operation ratio is 10%, heater is in 20 seconds
Runing time be 20 seconds * 10% be 2 seconds, then within a cycle of operation, the free time of heater is 18 seconds, humidity section
Gear it is higher, then runing time of the heater within a cycle of operation is longer.
When ambient humidity rises to high-grade humidity section by low-grade humidity section, corresponding continuous working period according to
Upshift number adjustment, for example, heater strip continues working 5 points when ambient humidity ramps up 1 grade (such as gear one jumps to gear two)
Clock；When ambient humidity ramps up 2 grades (such as gear one jumps to gear three), heater strip is continued working 10 minutes；Work as environmental wet
When degree ramps up 3 grades (such as gear one jumps to gear four), heater strip is continued working 15 minutes；When ambient humidity ramps up 4 grades
When (such as gear one jumps to gear five), heater strip is continued working 20 minutes；After continuous heating, then continuous heating state is exited,
It is worked with the corresponding operation ratio in humidity section after upshifing.
Ambient humidity is detected, when detecting ambient humidity is 55%, obtaining corresponding humidity section is gear two, then at this time
Heater is controlled to work with 20% operation ratio.
When ambient humidity changes, corresponding humidity section changes.If ambient humidity rises to 65%, then this
When corresponding humidity section be gear three, detection ambient humidity maintain the humidity section of gear three time span whether be more than
30 minutes, when the time span that ambient humidity maintains the humidity section of gear three is less than 30 minutes, i.e., in 30 minutes, ring
When border humidity drops to 55% by 65% again, then the operation ratio work that heater maintains gear two corresponding 20% is controlled.
When the time span that ambient humidity maintains the humidity section of gear three is more than 30 minutes, then gear three is compared
The humidity value in the humidity section of the humidity value and gear two in humidity section, since the humidity value in the humidity section of gear three is greater than shelves
The humidity value in the humidity section of position two then shows ambient humidity rising at this time, and it is 1 grade that ambient humidity, which rises gear number, then controls
Heater was at continuous heating 5 minutes, then, was then worked with the operation ratio in the humidity section of gear three corresponding 30%.
When ambient humidity changes, 45% such as is fallen to by 55%, and then the corresponding humidity section of ambient humidity becomes
For gear one, and when ambient humidity maintains the time span in the humidity section of gear one and is more than 30 minutes, then gear one is compared
Humidity section humidity value and gear two humidity section humidity value, since the humidity value in the humidity section of gear one is less than
The humidity value in the humidity section of gear two, ambient humidity decline, it is less to coagulate pearl, in order to reduce energy consumption, control heater directly with
10% operation ratio work.
Refer to Fig. 2, the anti-dewdrop method for heating and controlling of the present embodiment, due to changing in humidity, so that corresponding humidity
When section changes, the operation ratio of heater does not change immediately therewith, but the variation that is delayed, so that the operation ratio of heater
More smoothly change, in this way, the heating temperature profile of heater also more mitigates, control is heated using the anti-dewdrop of the present embodiment
The heating temperature profile of method processed is a gradient ramp, and the operation ratio of the heater of traditional anti-dewdrop method for heating and controlling
Change immediately with the variation in humidity section, causing heating temperature profile to generate, fluctuation is more violent, and temperature curve is in saw
Tooth form, relative to traditional method for heating and controlling, the anti-dewdrop method for heating and controlling in the present embodiment can make heater work
Temperature is more stable, is conducive to extend the service life of heater.
