Fig. 1 is the method schematic diagram of an embodiment of cabinet humidity control method provided by the invention.
The embodiment of the invention, as shown in Figure 1.A kind of cabinet humidity control method includes step S110 and step
S120。
Step S110 obtains the humidity value in cabinet；
The step is humidity value obtaining step, and the relationship of humidity and frequency is considered in this programme, therefore, accurately, is had
Humidity value in the extraction cabinet of effect just facilitates the subsequent frequency to compressor to adjust accordingly.
The humidity value can be arranged according to wine cabinet/refrigerator humidity come concrete decision：
Such as：Humidity value in the cabinet is the live humidity value in cabinet, will not be set in wine cabinet/refrigerator in this case
Set humidity compensation.
For another example：Humidity value in the cabinet is live humidity value and compensation humidity in cabinet.In this case wine cabinet/cold
Humidity compensation can be set in hiding cabinet.
About the concrete operations of acquisition, at least it is contemplated that two ways：
Mode one：Realize the sensor of the included detection humidity of the device of this method；
Mode two：Realize the device external sensor of this method, the humidity information that receiving sensor is sent.
Step S120, analyzes humidity value, determines frequency reducing moisturizing or raising frequency wet down；
The step is compressor frequency rate-determining steps, it is generally the case that the humidity range of a permission is respectively provided in cabinet,
When being compared to the humidity value of extraction, humidity range progress is also relied on substantially：
Such as：When humidity value is lower than the first preset value, compressor frequency is reduced；
Such case betides high frequency situations, once humidity value has been lower than the minimum of the humidity range allowed in cabinet, needs
Frequency is reduced, to improve in-cabinet temperature, the condensation water generated in cabinet is reduced, increases the evaporation of steam, improve cabinet humidity.
For another example：When humidity value is higher than the second preset value, compressor frequency is promoted；
Such case typically occurs in low frequency situation, once humidity value is higher than the peak of the humidity range allowed in cabinet,
Substantially in-cabinet temperature is higher, humidity over limit, needs to be promoted frequency, reduces in-cabinet temperature, reduces the evaporation of steam, reduces in cabinet
Humidity.
For another example：When humidity value is between the first preset value and the second preset value, compressor maintains to work normally.
Such case typically occurs in cabinet humidity and is in the humidity range allowed in cabinet, transports by the nominal frequencies of compressor
Turn.
It can achieve the purpose that raising frequency dehumidifying, frequency reducing humidification by the above method, and then cabinet humidity is flexibly adjusted
It is whole, slight fluctuations in allowed limits.
Another specific embodiment of the present invention, as shown in Figure 2.A kind of cabinet humidity control method includes step S210 and step
Rapid S220.

In the present embodiment, humidity value is the adduction of live humidity value and compensation humidity in cabinet.
Step 220, humidity value is analyzed, determines frequency reducing moisturizing or raising frequency wet down；
When humidity value is lower than the first preset value, compressor frequency is reduced；
When humidity value is higher than the second preset value, compressor frequency is promoted；
The concept for making full use of tolerance in the present embodiment, by adjustment control in the reasonable margin of tolerance.Wherein first
Preset value is RHLower limit valueAnd the difference of third tolerance, the second preset value are RHUpper limit valueThe sum of with the first tolerance, RHUpper limit value、RHLower limit valueRespectively
The upper limit value of the humidity range allowed in cabinet, lower limit value, the humidity range are preset value.
It is to be appreciated that in cabinet preset humidity range, the first tolerance, third tolerance occurrence be according to cabinet specifically answering
It is determined with, specific requirement.And various values, the range being related in other embodiments can be determined using which, after
Text repeats no more.
Step 230, according to step 220 as a result, the frequency of adjustment compressor；
The halt adjusted every time is defined in the present embodiment.
Such as：During reducing compressor frequency, when humidity value is higher than third preset value, stop reducing compressor
Frequency；Third preset value is RHLower limit valueThe sum of with the 4th tolerance.
For another example：During promoting compressor frequency, when humidity value is lower than four preset values, stop promoting compression
Unit frequency；4th preset value is the difference of RH upper limit value and the second tolerance.
It should be noted that the temperature value compensation temperature value in cabinet can be measured first before carrying out the analysis of S220 again, into
Row in-cabinet temperature judgment step, in-cabinet temperature judgment step include：Judge in-cabinet temperature value whether in pre-set interval；Compressor
The operation of reduction compressor frequency in frequency controlling step is lower than the first preset value in humidity value and in-cabinet temperature value is default
It is executed when in section.
Come so that in-cabinet temperature value includes the adduction mended in collecting temperature value T cabinet with temperature compensation value T in cabinet as an example below detailed
It is thin to explain above step：
By in-cabinet temperature value and compensation temperature value compared with setting value, the step of subsequent humidity compares, such energy are determined
Improve the speed of humidity adjustment.
Such as：If judging whether humidity value is lower than the first preset value in pre-set interval, when being lower than the first preset value,
Reduce compressor frequency；When being not less than the first preset value, then judge whether the humidity value obtained is more than or equal to the second preset value,
If it is greater than or equal to the second preset value, compressor frequency is promoted；
If judging whether the humidity value obtained is more than or equal to the second preset value not in pre-set interval, if it is greater than or equal to the
Two preset values promote compressor frequency.
Certainly, in some other embodiments, temperature-compensating can be ignored or be not suitable for in-cabinet temperature value, directly be to adopt
Temperature value in the cabinet of collection.
Next, the control method of cabinet humidity is described in detail by the process of complete set by the present invention, such as Fig. 3 institute

Step 330, < t2 is set using+T benefit-T in formula t1 < T cabinet to be compared as temperature value；
If formula is set up, 340 are entered step；
If formula is invalid, 350 are entered step；
Step 340, formula RH is utilizedIn cabinet+RHIt mends< RHLower limit valueThird tolerance analyzes humidity value；
If formula is set up, 340-1 is entered step；
If not, then enter step 350；
Step 340-1 reduces compressor operating frequency into frequency reducing moisturizing mode, and utilizes RHIn cabinet+RHIt mends>RHLower limit value+ the
Four tolerances analyze the humidity value during frequency reducing；
If satisfied, then stopping frequency reducing moisturizing；
If not satisfied, then return step 340.
Step 350, RH is utilizedIn cabinet+RHIt mends>RHUpper limit value+ the first tolerance analyzes humidity value；
If satisfied, then entering step 350-1；
If not satisfied, then entering step 360；
Step 350-1 promotes compressor operating frequency into raising frequency dehumidification mode, and utilizes RHIn cabinet+RHIt mends< RHUpper limit value-
Second tolerance analyzes humidity value；
If satisfied, then stopping, raising frequency dehumidifying is exited；
If not satisfied, then returning to 350.
