A heater control means 38 for controlling the water temperature and a time measuring means 39 for counting the time elapsed since the start of a specific operation are provided.

Next, the driving operation in this embodiment will be described.
First, when the operation switch of the operation unit 6 is operated, the control unit 35 opens the drain valve 31 to drain the water in the water storage chamber 8, and when an OFF signal is detected by the water level sensor 26, the water supply valve 28. Is opened and the inside of the water storage chamber 8 is washed with water. When a predetermined time has elapsed, the drain valve 31 is closed to supply the water flowing in from the water supply valve 28 into the water storage chamber 8, and the water level sensor 26 is turned on. When the signal is detected, a water replacement mode is performed in which the water supply valve 20 is closed assuming that a predetermined amount of water has been supplied into the water storage chamber 8.

  When the water replacement mode is completed, the control unit 35 drives the heater 24 based on the value detected by the temperature sensor 25 so that the stored water temperature is within a predetermined temperature range (for example, between 63 ° C. and 65 ° C.). The start-up mode is controlled by the heater controller 38 and the mist motor controller 36 and the blower motor controller 37 so that the mist motor 14 and the blower motor 23 have a predetermined rotational speed.

  When the start-up mode ends, the control unit 35 determines that the mist motor 14 and the blower motor 23 are based on the humidification level and the airflow level set by the humidification switch (not shown) and the airflow switch (not shown). The rotational speed is controlled by the mist motor control means 36 and the blower motor control means so as to drive at a predetermined rotational speed, and the heater heater control means 38 determines the ON / OFF state of the heater 16 based on the detection value of the temperature sensor 25. By switching and controlling, a normal operation mode is executed in which a mist operation is performed to bring the water storage temperature in the water storage chamber to a predetermined temperature range that matches the humidification level and the air volume level.

  Here, the normal operation mode will be described in detail. The mist motor control means 36 changes the rotation speed of the mist motor 14 within the range of 800 to 1400 rpm, and the blower motor control means 37 causes the blower motor 23 to fall within the range of 400 to 800 rpm. In the water storage chamber 8, the mist operation is performed at a rotational speed that matches the air flow level by changing the rotational speed in the interior, and the temperature detected by the air temperature sensor 32 becomes a value that matches the humidification level. The heater temperature is controlled by changing the ON / OFF state of the heater 24 with the heater control means 38 so that the temperature of the stored water is changed and the temperature detected by the temperature sensor 25 changes within the range of about 30-40 ° C. .

  As a result, the mist motor 14 is driven to rotate the rotating body 9, so that the rotating body 9 pumps up the water in the water storage chamber 8 by the centrifugal force of the rotation and scatters the air. The water pushed up along the outer wall and the inner wall of the rotating body 12 is scattered around the outer wall of the lower part 12 of the rotating body, and the water pushed up along the inner wall of the lower part 12 of the rotating body 12 The water is dispersed from the plurality of scattering ports 22 formed at the ends, and the scattered water passes through the porous portion 21 of the porous body 13 and is crushed, thereby refining the water particles to nanometers (nm). A mist of a size is generated and negative ions are generated by the Leonard effect due to the refinement of water particles. A plurality of scattering ports 22 formed in a plurality of stages around the upper end of the rotating body lower part 12 Lower Since the positions of the spouts 22 are shifted so that they are arranged in a zigzag pattern, the amount of water falling from the spouts 22 without falling to the surroundings is reduced, and the water is efficiently scattered to the surroundings. Can be increased.

  Further, when the porous body 13 is attached to the outer periphery of the upper portion of the rotating body lower portion 12, the welded portion 20 of the porous body 13 is attached so as to be located on the side opposite to the screw 17 inserted into the screw hole 16 on the side surface of the fixed portion 10. The bias of the center of gravity generated in the rotating body 9 when the porous body 13 rotates together with the rotating body 9 is that the screw 17 inserted into the side surface of the fixed portion 10 is inserted into the opposite side of the welded portion 20. It is possible to prevent the occurrence of vibration and sound due to the canceling, and thereby the rotating body 9 rotating.

  In addition, the drive shaft 15 of the mist motor 14 is inserted into the fixed portion 10 of the upper portion 11 of the rotating body 11, and the fixed portion is inserted by inserting a screw 17 into a threaded hole 16 formed on the side surface of the fixed portion 10 in that state. 10 is pressed against the drive shaft 15, and the fixed portion 10 is fixed to the drive shaft 15. Therefore, the gap between the fixed portion 10 and the drive shaft 15 does not shake the rotating body 9, thereby It is possible to prevent the center of gravity of the rotating body 9 from being generated during rotation and to prevent vibration and sound from being generated by the rotation of the rotating body 9.
