So, in an embodiment of the present invention, detect the bad degree of exhaust, when the exhaust dry operating is spun out, stop the exhaust dry operating and transfer to the cyclic drying running, running is stopped.Thus, can suppress the dry operating time invalidly spins out.

Quoting Figure 14 is described in detail the order that stops this exhaust dry operating and transfer to cyclic drying running.

Begin the cyclic drying running at step S1400.In this cyclic drying running, close inlet valve 13, stop up air entry.Air in the housing 2 (cabinet) can not be attracted from air entry, with the dry circulation with air of order transposing of wind pushing mechanism, heating arrangements, outer bucket, desiccant body, wind pushing mechanism, carries out the drying of being undertaken by general cyclic drying running.

When selecting energy-conservation exhaust dry operating, the cyclic drying running (warm wind air-supply) of step S1401 is carried out the time of 10 minutes～60 minutes degree.The rotation speed of the fan of the wind pushing mechanism of this moment is set at 13500RPM.After through 10 minutes～60 minutes, in step S1402, reduce rotation speed of the fan.The rotating speed that reduces is the 4800RPM degree.

After making this rotating speed reduction, carry out the opening action of inlet valve 13, air entry is opened (step S1403).Promptly, carry out opening action when air entry is configured to open, then cover dehumidification portion in the housing 2 (cabinet) towards the exhaust dry operating that flows and get into the air in above-mentioned wind path imports housing 2 (cabinet) of the air of above-mentioned wind pushing mechanism at inlet valve 13.

If get into this exhaust dry operating, improve the rotation speed of the fan (step S1404) that reduces for the time being at step S1404.When this rotation speed of the fan rises, carry out the air pressure inside of outer bucket 20 and the mensuration of rotating speed and detect (step S1405).

This air pressure is measured (detection) and is carried out with pressure detecting mechanism.The above-mentioned detection of pressure detecting mechanism dual-purpose accumulates in the level sensor 134 of the water level in the outer bucket 20.Since dual-purpose level sensor 134, thus need not specially to prepare the air pressure analyzer, cheap and simple in structure.In addition, the mensuration of rotation speed of the fan detects with the microcomputer 150 of above-mentioned control device 138 and the drive circuit 154 of fan 61 and detects.The drive circuit 154 that comprises microcomputer 150, fan 61 is referred to as " rotary speed tester structure ".Comprise pressure detecting mechanism, the rotary speed tester structure is referred to as " the bad testing agency of exhaust ".

In addition, if after step S 1405 rotation speeds of the fan have reached 13400RPM, the drainage channel that then comprises exhaust impeded drainage flexible pipe does not have the obstruction of the end of a thread etc., detects that to be judged to be exhaust good, continues exhaust dry operating (step S1406).In this exhaust dry operating, also utilize the waste heat that is stored in the housing 2 (cabinet), heater is disconnected, thereby becomes energy-conservation.And, under the state that stays open inlet valve 13, make rotation speed of the fan be 13500RPM be rotated, if through the dry operating of stipulated time, then finish running (step S1407).

In step S1405, when rotation speed of the fan does not reach 13400RPM, be 200mmH with the atmospheric pressure value ₂O is target detection air pressure change (step S1408).Detect the rising (step S1409) of rotating speed when detecting this air pressure change.And, be 200mm H at air pressure ₂In the O,, then continue exhaust dry operating (step S1410) if after rotating speed has reached 12000RPM.

When the exhaust dry operating of step S1410,, then equal with the exhaust dry operating of step S1406 if remove the low this point of rotation speed of the fan.If the exhaust dry operating of step S1410 through the stipulated time, then finishes running (step S1411).

In step S1409, be 200mm H at air pressure ₂In the O, when rotating speed can not reach 12000RPM, rotation speed of the fan is reduced to 4800RPM (step S1412), transfers to the cyclic drying that makes inlet valve 13 carry out closing motion (step S1413) and turn round.

In step S1409, be 200mm H like this at air pressure ₂In the O, judge that can rotation speed of the fan cross 12000EPM, be to become the exhaust dry operating, still become the cyclic drying running.Bad testing agency of exhaust that constitutes or the program of constructing in microcomputer 150 are carried out through comprising above-mentioned pressure detecting mechanism, rotary speed tester structure in this judgement.

The judgement that the exhaust of the drainage channel that contains scupper hose that relates to the suitability of exhaust dry operating is very denied detects to be carried out with the bad testing agency of exhaust automatically, so serviceability is good.In addition, the bad testing agency of exhaust that constitutes with pressure detecting mechanism, rotary speed tester structure need be containing the obstruction checkout gear of the direct detection line leader obstruction that is equipped with on the drainage channel of scupper hose etc., and is simple and cheap.

Have again, in step S1413,, then improve the rotation speed of the fan (step S1414) reduced for the time being if after closing inlet valve 13 and transferring to the cyclic drying operation.Rotation speed of the fan is brought up to 13400RPM and is carried out with the heating of heater, so carry out the drying (step S1415) of being undertaken by the air-supply of warm wind.After the drying of warm wind air-supply, blow (step S1416) cools off, and finishes running (step S1417).

In cyclic drying running, inlet valve 13 configurations (inlet valve cuts out) become, cover from the air of housing 2 (cabinet) in wind path to flow into, and from dehumidification portion towards the wind pushing mechanism moving air.Promptly, desiccant air carries out drying with the sequential loop of wind pushing mechanism, heating arrangements, outer bucket, desiccant body, wind pushing mechanism.This not carrying out to the cyclic drying running of the exhaust of drainage channel owing to when the exhaust of drainage channel is bad, transfer to the cyclic drying running automatically from the exhaust dry operating is so serviceability is good.

When the on-off action of inlet valve 13, rotation speed of the fan is reduced to the 4800RPM degree.Rotating speed through this fan reduces, and air quantity reduces, thereby even the few motor of driving force also can reliably carry out the switching of inlet valve 13, can prevent the faulty operation in the switched and transferred of cyclic drying running, exhaust dry operating.
