Or intrinsic other step of equipment or unit.
Fig. 1 is the method schematic diagram of an embodiment of the cabinet humidity control method that the present invention provides.
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；
This step is humidity value obtaining step, in view of humidity and the relation of frequency in this programme, therefore, accurately, has
The humidity value extracted in cabinet of effect just facilitates the follow-up frequency to compressor to adjust accordingly.
This humidity value can arrange concrete decision according to the humidity of wine cabinet/refrigerator:
Such as: the situ wet angle value that the humidity value in this cabinet is in cabinet, in this case will not set in wine cabinet/refrigerator
Put humidity to compensate.
The most such as: the situ wet angle value that the humidity value in this cabinet is in cabinet and compensation humidity.In this case wine cabinet/cold
Humidity can be arranged in hiding cabinet compensate.
About the concrete operations obtained, two ways at least can be considered:
Mode one: the device realizing this method carries the sensor of detection humidity；
Mode two: realize the device external sensor of the method, receives sensor and sends the humidity information of coming.
Step S120, is analyzed humidity value, determines frequency reducing moisturizing or raising frequency wet down；
This step is compressor frequency rate-determining steps, it is generally the case that be respectively provided with a humidity range allowed in cabinet,
When the humidity value extracted is compared, the most substantially rely on this humidity range and carry out:
Such as: when humidity value is less than the first preset value, reduce compressor frequency；
This situation betides high frequency situations, the minimum of the humidity range allowed in once humidity value has been less than cabinet, needs
Frequency to be reduced, improves in-cabinet temperature, the condensation water produced in reducing cabinet, strengthens the evaporation of steam, improves cabinet humidity.
The most such as: when humidity value is higher than the second preset value, promote compressor frequency；
This situation typically occurs in low frequency situation, and 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 promote frequency, reduces in-cabinet temperature, reduce the evaporation of steam, reduces in cabinet
Humidity.

Preset value is RHLower limitIt is RH with difference, second preset value of the 3rd toleranceHigher limitWith the first tolerance sum, RHHigher limit、RHLower limitIt is respectively
The higher limit of humidity range of permission, lower limit in cabinet, this humidity range is preset value.
It is to be appreciated that default humidity range, the first tolerance, the occurrence of the 3rd tolerance are specifically should according to cabinet in cabinet
Determine with, specific requirement.And various values, the scope related in other embodiments can use which to determine, after
Literary composition repeats no more.
Step 230, according to the result of step 220, adjusts the frequency of compressor；
Define the halt of adjustment every time in the present embodiment.
Such as: during reducing compressor frequency, when humidity value is higher than three preset values, stop reducing compressor
Frequency；3rd preset value is RHLower limitWith the 4th tolerance sum.
The most such as: during promoting compressor frequency, when humidity value is less than four preset values, stop promoting compression
Unit frequency；4th preset value is the difference of RH higher limit and the second tolerance.
It should be noted that before carrying out the analysis of S220 again, can first measure the temperature value in cabinet and compensate temperature value, enter
Row in-cabinet temperature judges that step, in-cabinet temperature judge that step includes: judge that in-cabinet temperature value is whether in pre-set interval；Compressor
The operation reducing compressor frequency in frequency controlling step is being preset less than the first preset value and in-cabinet temperature value at humidity value
Perform time in interval.
Include in cabinet in collecting temperature value T cabinet by in-cabinet temperature value below and temperature compensation value T mends add and as a example by come in detail
Carefully explain above step:
By in-cabinet temperature value and the comparison that compensates temperature value and setting value, determine follow-up humidity ratio compared with step, such energy
Improve the speed that humidity adjusts.
Such as: if in pre-set interval, it is judged that whether humidity value is less than the first preset value, when less 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 more than or equal to the second preset value, promote compressor frequency；
If not in pre-set interval, it is judged that whether the humidity value of acquisition is more than or equal to the second preset value, if more than or equal to the
Two preset values, promote compressor frequency.
Certainly, at some in other embodiment, in-cabinet temperature value can be ignored or inapplicable temperature-compensating, directly for adopting
Temperature value in the cabinet of collection.
