Start closet battery saving mode switch among the process S1 and carry out the running of closet battery saving mode, the running formation initial stage running continuously of pressure fan 15 and compressor 27 dehumidifies to the air in the closet 36 among the process S2.Process S3 is by judging whether to surpass the predefined the 3rd T3 (being 50 minutes in the embodiments of the invention) that fixed time, as surpassed the running of termination initial stage and move to process S4, as also above then not being back to process S2 with ing.

Process S4 predefinedly decides humidity A (being 50% in an embodiment of the present invention) and carries out process S5 interruption shown below when not reaching and turn round for judging whether air humidity is higher than.

Process S5 shuts down for making pressure fan 15 and compressor 27, process S8 is shorter than first of the 3rd setting-up time T3 T1 (being set at 15 minutes in an embodiment of the present invention) that fixed time by judging whether to have surpassed, if do not surpass then return course S5, if surpassed then move to process S7.

Process S7 turns round continuously for making pressure fan 15 and compressor 27, process S8 is by judging that whether this continuous operation time surpasses second T2 (being set at 12 minutes in an embodiment of the present invention) that fixed time, be not back to process S7 if do not surpass, be back to process S4 if surpassed.

In addition, in process S4, when above decide humidity A (setting humidity in the embodiments of the invention is 50%), shift to process S7.Thus, pressure fan 15 and compressor 27 do not shut down and keep the operating condition of pressure fan 15 and compressor 27.

Below, under the occasion of above-mentioned air dehumidifier being used in closet 36, describe with reference to Fig. 6, Fig. 7 about the relation of the variation of the humidity in the closet 36 with operating condition.

In the closet narrower 36 than the room, make pressure fan 15 and compressor 27 work, the humidity in the closet is shown in the solid line of Fig. 6, sharply descend in the early stage and then gently change, after, even the reduction amplitude of its humidity that turns round continuously is very little, form basic stable state.So, in an embodiment of the present invention,, be kept in continuous operation in the period at this section from the entry into service to humidity, reducing unconspicuous this section time set by the 3rd T3 that fixed time.

Because air humidity is decided humidity by being lower than after surpassing the 3rd T3 that fixes time, to shown in the process S8, be interrupted running as the process S5 in the above-mentioned flow chart, the humidity of this moment changes shown in the dotted line among Fig. 6, and indentation descends.

In such interruption operation process, surpass first fix time after, even pressure fan 15 and compressor 27 quit work, the air humiditys in the closet 36 also can remain below institute decides under the state of humidity A, can realize the high dehumidifying of power consumption poor efficiency.

In addition, compressor 27 stop and work and humidity irrelevant, be to switch, therefore according to predefined first fix time T1 and second T2 that fixes time, the number of times that stops and turning round of compressor 27 can be reduced, thereby the service life of compressor 27 can be prolonged.

When carrying out the running of above-mentioned interruption, when opening 36 of closets, the wetly air that contains in the room enters closet 36, and the humidity in the closet 36 is as shown in after the X of Fig. 7, rise to decide more than the humidity A (being set at 50% in an embodiment of the present invention).

Humidity in humidity sensor 22 detects closet 36 surpassed when deciding humidity A, do not carry out shutting down of pressure fan 15 and compressor 27, and control pressure fan 15 and compressor 27 make its state that keeps on the go.After a period of time, when the measured humidity of humidity sensor be reduced to decide humidity A when following, control pressure fan 15 and compressor 27 stop its running, operation is interrupted running once more, the variation indentation of humidity reduces gradually.Thereby reduce power consumption in the process that can in closet 36, dehumidify.

As mentioned above, under the occasion of use in closet 36, because compressor 27 turns round to the 3rd T3 that fixes time continuously from beginning, humidity in the closet 36 can fully drop to be lower than institute decide humidity A above the 3rd T3 that fixes time after compressor 27 be halted state in first T1 that fixes time, in second T2 that fixes time, be operating condition, can not increase the burden of compressor like this, reduce power consumption and but can make humidity remain on institute to decide below the humidity, carry out the interior dehumidifying of closet 36 efficiently.

In addition, in the early stage after the running when detect by humidity sensor 22 humidity above when deciding humidity A, control pressure fan 15 and compressor 27 do not quit work and carry out continuous running, so, when humidity in 36 of closets are opened closet 36 rises, can promptly dehumidify with the humidity in the closet 36 drop to decide below the humidity A.

In addition, as the above embodiments preferably before being interrupted running initial operating stage running make humidity drop to institute as early as possible to decide below the humidity A, but the initial stage of also can not carrying out turns round and only is interrupted running.

In addition, in the above-described embodiment, being interrupted first of running T1 and second the 3rd T3 that fixes time when fixing time T2 and initial stage running that fix time is pre-set value, also can adjust knob or button change first fix time T1 or second fix time T2 or the 3rd T3 that fixes time by being provided with.

This occasion, the 3rd T3 that fixes time when first T1 that fixes time, second that adjusts the running of suitable interruption according to the size of closet 36 fixes time T2 and initial stage running thus, can adjust suitable operating condition according to the size of closet 36.

In addition, under the interruption operating condition, pressure fan 15 and compressor 27 are all quit work with the amount of saving energy, also can only allow compressor 27 quit work.

According to air dehumidifier of the present invention, under the occasion of in closet, using, carry out in first T1 that fixes time being the interruption running of duty repeatedly for halted state, in second T2 that fixes time, can not increase the burden of compressor, reduce power consumption in the process that in to closet, dehumidifies.

According to another air dehumidifier of the present invention, by adjusting device can according to the size of closet adjust that first of suitable interruption running fixes time or second fix time, thus, can adjust suitable operating condition according to the size of closet.

According to another air dehumidifier of the present invention, under the occasion of use in closet, because compressor is from beginning to the 3rd running continuously of fixing time, humidity in the closet can fully drop to be lower than decide humidity, compressor is halted state in first is fixed time after fixing time above the 3rd, is operating condition in second is fixed time, and can not increase the burden of compressor like this, reducing power consumption but can make humidity remain on institute to decide below the humidity, carry out the interior dehumidifying of closet efficiently.

According to another air dehumidifier of the present invention, the 3rd T3 that fixes time when adjusting suitable initial stage running according to the size of closet thus, can adjust suitable operating condition according to the size of closet 36.

According to another air dehumidifier of the present invention, though open and close humidity in the back closet of closets rise to decide more than the humidity, also can promptly drop to decide below the humidity.
