On the other hand, judging part is in situation about judge to remove needing for the notice of water state, and is same with above-mentioned the 1st embodiment, carries out identical judgement when humidification running beginning with through the running of the humidification after the stipulated time time.That is, during in humidification when beginning running with through the running of the humidification after the stipulated time, continue the 3rd at the ON signal from test section 70 and judge time T 5(for example 20 seconds) situation under, judgement section judges is for removing the notice that needs for water state.

And the judgement of the judging part when connecting the timer setting is identical with the 1st embodiment.

Same with the 1st embodiment, the air purifier of present embodiment has automatic operation mode, under automatic operation mode, switches the humidifications running according to the water levels in the drip tray 40 that is detected by test section 70 and turns round with the air cleaning of not carrying out humidification.Namely, in situation about turning round under the automatic operation mode, having notified when humidification turns round needs to turn round for switching to air cleaning in the situation of water state at air purifier 1, and, then, when air cleaning is turned round, removed and switched to the humidification running in the situation of water supply state.And, in air purifier 1, the rotation speed of the fan the when rotation speed of the fan when setting the humidification running and air cleaning running, still, the rotation speed of the fan the when rotation speed of the fan during the humidification running is set as and turns round than air cleaning is large.Therefore, for example set the rotating speed corresponding with the 1st tap～the 5th tap as the rotating speed of fan 28, in the situation that, rotating speed maximum at the rotating speed of the 1st tap reduces according to the order of the 2nd tap, the 3rd tap, the 4th tap, the 5th tap, rotation speed of the fan when setting the 2nd tap and turning round as humidification, the rotation speed of the fan the when rotating speed of setting any one tap in the 3rd tap～the 5th tap turns round as air cleaning.

Therefore, drive control part is controlled to be the 2nd tap (rotating speed during the humidification running) with the rotating speed of fan 28 when humidification turns round, and, when air cleaning is turned round, the rotating speed of fan 28 is controlled to be any one tap (rotating speed during the air cleaning running) in the 3rd tap～the 5th tap.Here, when turning round, humidification notified in the time of to switch to the air cleaning running for water state the rotation speed of the fan the when rotation speed of the fan when drive control part turns round humidification switches to the air cleaning running.And; when turning round, air cleaning removed in the time of to switch to the humidification running for water state; removed need for behind the water state, passed through predefined fan protection time T 6(for example 3 minutes) time, the rotation speed of the fan the when rotation speed of the fan when drive control part turns round air cleaning switches to the humidification running.That is, when air cleaning is turned round, removed the water supply state and switched to humidification when running, before through fan protection time T 6, the rotation speed of the fan the when rotation speed of the fan when drive control part does not turn round air cleaning switches to the humidification running.

And, after the running of beginning humidification, receiving in the situation of ON signal from test section 70, drive control part makes humidifying rotor 50 rotations, receives in the situation of OFF signal from test section 70 when humidification turns round, and drive control part stops the rotation of humidifying rotor 50.And, the rotation of humidifying rotor 50 is stopped after, the water surface elevation in drip tray 40 becomes in the situation more than the specified altitude, drive control part makes humidifying rotor 50 rotations.
