First, when an operation switch (not shown) of the operation unit 6 is operated, the control unit 32 opens the drain valve 28 to drain the water in the water storage tank 8, and when the water level sensor 23 detects an OFF signal, the water supply valve A cleaning operation is performed by opening the valve 25 and flushing the inside of the water storage tank 8 with water, and after a predetermined time elapses, the drain valve 28 is closed to supply the water flowing from the water supply valve 25 into the water storage tank 8 and to supply the water level sensor. When the ON signal is detected in 23, a cleaning mode is performed in which the water supply valve 25 is closed assuming that a predetermined amount of water has been supplied into the water storage tank 8 (step S101).

When the cleaning mode in step S101 is completed, the control unit 32 turns on the heater 21 by the heater control means 35 until the water storage temperature detected by the water storage temperature sensor 22 becomes equal to the room temperature, and the mist motor 11 and the mist motor 11 and the control unit 32 are turned on. A start-up mode is performed to execute a start-up operation controlled by the mist motor control means 33 and the blower fan control means 34 so that the blower fan 14 has a predetermined rotation speed (step S102).

When the start-up mode of step S102 is completed, the control unit 32 uses the mist motor 11 and the blower fan 14 at a predetermined rotation speed based on the humidification level and the air volume level set by the humidification switch and the air volume switch (not shown).

A normal operation mode for executing a mist operation within a predetermined temperature range is performed (step S103).

Further, when the control unit 32 determines that the water level of the water storage tank 8 becomes equal to or lower than the lower limit water level and the water level sensor 23 outputs an OFF signal during the mist operation, the control unit 32 opens the water supply valve 25 and enters the water storage tank 8. When it is determined that the water level of the water storage tank 8 has reached the upper limit water level and the water level sensor 23 has output an ON signal, the water supply valve 25 is closed to stop the water supply into the water storage tank 8. , It is possible to maintain a water level at which mist operation can be carried out at all times.

Further, the control unit 32 starts time counting when the normal operation mode is started, and when it is determined that the counted time has elapsed a predetermined operation time, the control unit 32 starts a water replacement operation described later and determines the predetermined water replacement time. When it is determined that 10 minutes have passed, the water replacement operation is terminated and the mist operation is restarted.

When it is determined that the time elapsed from the start of the normal operation mode in step S103 is 16 hours, or that the operation switch is operated during the normal operation mode and an instruction to end the mist operation is given, the control unit 32 determines that the mist motor After stopping 11, the drain valve 28 is opened to drain the water in the water storage tank 8, and after a predetermined time has passed, the water supply valve 25 is opened to clean the inside of the water storage tank 8 and then the drain valve 28 is closed. A cleaning operation is performed in which a predetermined amount of water is stored in the water storage tank 8 by valve, and then a sterilization operation is performed for 10 minutes in which the heater 21 is turned on and the water is heated to around 65 ° C. to sterilize the water. After a lapse of minutes, a cooling operation for cooling the inside of the water storage tank 8 is executed, and when the water storage temperature becomes less than 60 ° C., a cleaning mode is performed in which the drain valve 28 is opened to drain water (step S104).

When the cleaning mode of step S104 is completed, the control unit 32 shifts to the drying mode (step S105), and the blower fan control means 34 controls the blower fan 14 to drive at a predetermined rotation speed (for example, 800 rpm). A drying operation is carried out in which the blower fan 14 is continuously driven for a predetermined time (for example, 3 hours), and when it is determined that 3 hours have passed, the blower fan 14 is stopped to end the operation.

Next, a cleaning method around the water storage tank 8 in this embodiment will be described.

When this happens, the operator removes the top panel 4 to open the inside of the instrument body 1 and removes the fixing member 42 from the mounting bracket 37 by removing the screw 40 using a screwdriver, and removes the fixing member 42 from the mounting bracket 37, and removes the wind tunnel 15 and the air-water separation case. 17 is removed from the upper part of the water storage tank 8 so that the upper part of the water storage tank 8 is open.

Then, when the upper part of the water storage tank 8 is opened, the flange surface 44 constituting the upper part of the water storage tank 8 can be wiped and cleaned. Therefore, water remains on the flange surface 44 to form the tank wall surface 36 and the flange surface. It is possible to prevent the 44 from corroding to form a gap, and the humidified air leaking from the gap during mist operation to reduce the amount of humidified air blown into the room and reduce the humidifying efficiency of mist operation. ..

As described above, the fixing member 42 for fixing the mounting location of the air cavity 15 as an air flow passage and the air-water separation case 17 is installed on the tank wall surface 36 of the water storage tank 8 so as to be detachable from the mounting bracket 37 with a screw 40. As a result, when the cleaning work in the vicinity of the water storage tank 8 is performed, the fixing member 42 can be removed and the flange surface 44 of the water storage tank 8 can be wiped and cleaned, so that water is surely prevented from remaining on the flange surface 44. It is possible to prevent a situation in which the tank wall surface 36 and the flange surface 44 are corroded by the residual water to form a gap, and the humidified air leaks from the gap during mist operation to reduce the humidification efficiency in the room. it can.

Further, since the fixing member 42 can be attached / detached by a simple attachment / detachment means in which the adhesive surface 47 of the fixing member 42 is screwed to the attachment surface 39 of the attachment fitting 37 with a screw 40, the fixing member 42 and the attachment fitting 37 can be attached / detached. It does not require complicated processing and can prevent an increase in cost.

In the present embodiment, the attachment / detachment means is a screw 40, and the fixing member 42 can be attached / detached from the mounting bracket 37 by the screw 40. However, the present invention is not limited to this, and the fixing member 42 can be attached / detached from the water storage tank 8. For example, the water storage tank 8 is formed by forming a protrusion on the tank wall surface 36 that enables positioning of the fixing member 42 and forming a locking portion that is locked to the protrusion on the fixing member 42. The flange surface 44 may be cleaned by removing the fixing member 42 from the protrusion on the tank wall surface 36 when cleaning the vicinity.
