And a heater control means 53 for controlling the above.

Next, the operation from the start to the end of the operation in this embodiment will be described based on the flowchart of FIG.
First, when the operation switch 34 of the operation unit 6 is operated or the operation start time set by the timer changeover switch 38 is reached, the control unit 50 opens the drain valve 31 to drain the water in the water storage chamber 8. When an OFF signal is detected by the water level sensor 26, the water supply valve 28 is opened to perform a cleaning operation for washing the water storage chamber 8 with water. After a predetermined time has passed, the drain valve 31 is closed to enter the water supply valve 28. When the water level sensor 26 detects an ON signal, a water replacement mode is performed in which the water supply valve 28 is closed assuming that a predetermined amount of water has been supplied into the water storage chamber 8 (step S101). ).

  When the water replacement mode in step S101 is completed, the control unit 50 drives the heater 24 based on the detection value of the water storage temperature sensor 25 so that the water storage temperature T is equal to the room temperature detected by the intake air temperature sensor 33. Until the heater heater 24 is turned on by the heater control means 53, the start-up mode is controlled by the mist motor control means 51 and the blower fan control means 52 so that the mist motor 11 and the blower fan 16 have a predetermined rotational speed. Perform (step S102).

  When the start-up mode in step S102 ends, the control unit 50 causes the mist motor 11 and the blower fan 16 to rotate at a predetermined number of revolutions based on the humidification level and the airflow level set by the humidification switch 36 and the airflow switch 37. The mist motor control means 51 and the blower fan control means 52 are controlled so as to drive, and the heater heater 24 is controlled by switching the ON / OFF state of the heater 24, so that the humidification level and the air flow level are controlled. A normal operation mode for executing a mist operation within a predetermined temperature range in accordance with is performed (step S103).

  The normal operation mode will now be described in detail. The mist motor control means 51 changes the number of revolutions of the mist motor 11 within the range of 800 to 1400 rpm, and the blower fan control means 52 changes the speed of the blower fan 16 to 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 water heater temperature is changed, and the heater heater control means 53 switches the ON / OFF state of the heater 24 so that the temperature detected by the water reservoir temperature sensor 25 changes within a range of about 30 to 40 ° C.

  When the end condition of the normal operation mode in step S103 is satisfied, the control unit 50 stops the mist motor 11 and then opens the drain valve 31 to drain the water in the water storage chamber 8, and when a predetermined time has elapsed, the water supply valve 28 is opened, the inside of the water storage chamber 8 is washed, the drain valve 31 is closed, and a water replacement operation for storing a predetermined amount of water in the water storage chamber 8 is performed, and the heater 24 is turned on to heat the water. A sterilization operation for performing sterilization is performed for a predetermined time, and after the predetermined time has elapsed, a cleaning mode is performed in which the water storage chamber 8 is cooled to drain the water in the water storage chamber 8 (step S104).

Next, the cleaning mode in this embodiment will be described in detail based on the flowchart of FIG.
First, when the cleaning mode of step S104 is started, the controller 50 stops the mist motor 11 and then opens the drain valve 31 to drain the water in the water storage chamber 8, and when 8 minutes have passed, The valve 28 is opened and the inside of the water storage chamber 8 is washed with running water. When 20 seconds have elapsed, the water supply valve 28 is closed and the water storage chamber 8 is drained again. After 8 minutes, the water discharge valve 31 is closed and the water supply valve is closed. By opening 28, water is stored in the water storage chamber 8, and when an ON signal is detected by the water level sensor 26, a water replacement operation for closing the water supply valve 28 is performed (step S201).

  After performing the water replacement operation in step S201, the control unit 50 switches the heater 24 to the ON state and drives the mist motor 11 at a predetermined low rotational speed (for example, 600 rpm) lower than the rotational speed during the mist operation. Control is performed by the mist motor control means 51, and further, the sterilization operation is started, which is controlled by the blower fan control means 52 so as to drive the blower fan 16 at a predetermined low rotational speed (for example, 200 rpm) lower than the rotational speed during the mist operation. Thus (step S202), the water in the water storage chamber 8 is mixed to increase the water in the water storage chamber 8 evenly, and condensation is prevented from occurring at the air blowing port 2.

  When the heater 24 is turned on and the mist motor 11 is driven in step S202, the controller 50 turns off the heater 24 to stop heating when the water storage temperature T exceeds 65 ° C. When the temperature is lower than 63 ° C., the heater 24 is controlled by the heater control means 53 so that the heater 24 is turned on again and heated, and the temperature of the water stored in the water storage chamber 8 is around 65 ° C., which is a sterilizable temperature. By performing the holding heating operation, the water stored in the water storage chamber 8 is sterilized (step S203).

  When the heating operation for controlling the water in the water storage chamber 8 to around 65 ° C. is started in step S203, the control unit 50 detects that the temperature detected by the water storage temperature sensor 25 exceeds 65 ° C. during the heating operation, and the heater 24 is turned off. The time elapsed from the first time point when the state is switched to the state is counted, and it is determined whether the counted time has passed 10 minutes (step S204). If 10 minutes have passed, the heater 24 is turned off to disinfect the bacteria. The operation is terminated, and if 10 minutes have not elapsed, the heating operation in step S203 is continued.

  When the sterilization operation is completed in step S204, the control unit 50 opens the water supply valve 28 and starts water supply into the water storage chamber 8, and drives the blower fan 16 at a predetermined rotational speed. A cooling operation is performed to lower the water storage temperature to a temperature at which drainage is possible (step S205). When the water storage temperature in the water storage chamber 8 is lowered to a temperature at which water can be drained and drainage is completed, the cleaning mode is terminated.

  When the cleaning mode in step S104 is completed, the control unit 50 controls the blower fan 16 to be driven at a predetermined number of rotations (for example, 800 rpm) by the blower fan control means 52 and blows air to the water storage chamber 8 and the blower passage 17. A drying mode for preventing the growth of bacteria by drying is performed (step S105), and it is determined whether the driving time of the blower fan 16 has counted a predetermined time (for example, 3 hours) by a time measuring means (not shown), After counting for 3 hours, the blower fan 16 is stopped and the operation is terminated.

  As described above, by driving the blower fan 16 during the sterilization operation, even if the water in the water storage chamber 8 heated by the heater 24 evaporates and the water vapor rises to the blower port 2, the blower fan 16 is turned on. Since the water vapor in the vicinity of the air outlet 2 can be blown out of the appliance body 1 by being driven, condensed water does not adhere to the inner wall and the louver 3 constituting the air outlet 2, and the floor surface on which the appliance body 1 is installed. Can be prevented from getting wet.

  Moreover, the amount of nano mist generated in the water storage chamber 8 and reaching the air outlet 2 is reduced by driving the blower fan 16 at a predetermined low rotational speed lower than the rotational speed during the mist operation in the normal operation mode of 200 rpm. Furthermore, the amount of nano mist generated in the water storage chamber 8 is reduced by driving the mist motor 11 at a predetermined low rotation speed lower than the rotation speed during the mist operation in the normal operation mode of 600 rpm. Coupled with driving the fan 16 at a predetermined low rotational speed, the amount of condensed water adhering to the inner wall of the air outlet 2 and the louver 3 can be reduced.

  In addition, since the blower fan 16 is driven at a predetermined low rotation speed of 200 rpm, the heater 24 prevents the decrease in the water storage temperature of the water storage chamber 8 to the minimum, thereby preventing the sterilization rate in the water storage chamber 8 from decreasing. In addition, the driving sound and vibration generated from the blower fan 16 can be minimized.

  When the blower fan 16 is driven, air flows unidirectionally from the suction port 18 at the lower part of the instrument body 1 toward the blower port 2, so that water vapor is generated from the air inlet 8 a of the water storage chamber 8 during the sterilization operation. Since it does not rise, it is possible to prevent the internal microcomputer from malfunctioning due to condensation on the control unit 50 installed at the upper part of the air inlet 8a.

  Further, as described above, the nano mist and negative ions generated by the rotation of the rotating body 10 of the mist generating unit 15 are carried to the air blowing port 2 by the indoor air flowing in by the driving of the blower fan 16, and discharged from here to the room. It is possible to obtain a fresh feeling and a refreshing feeling of the mind and body, and when this nano mist and negative ions are generated, indoor dust and dust that are sucked and contained in the indoor air may directly hit the stored water. In the form of being entangled with the large nanomist generated in the mist generating section 15 and falling into the water storage chamber 8 by its own weight, dust, dust, odor, etc. in the indoor air are removed, and the water stored in the water storage chamber 8 is stored together with the large nanomist. It mixes, cleans the indoor air to make it clean and is released into the room together with nano mist and negative ions, and the dust and dirt mixed in the water stored in the water storage chamber 8 together with the water is the mist generating part 1 However, since the lower end of the rotating body 10 that is submerged in water is surrounded by the concave filter part 23 in the water, the water supplied to the rotating body 10 always passes through the filter part 23 and becomes dusty. Only clean and clean water from which dust and dust have been removed is supplied, and sanitary nano mist and negative ions are generated and released into the room, and indoor air is again supplied to the mist generation unit 15 to generate dust and dirt. Various bacteria, odors and the like are removed, and this circulation is repeated, so that the room gradually becomes clean and refreshing air, and a fresh feeling and a refreshing feeling of mind and body are obtained.

  The filter unit 23 can be used continuously for a long period of time while maintaining the removal performance by performing maintenance such as periodic removal and cleaning after the end of the cleaning mode.

  Further, as described above, the humidified air of nano mist and negative ions generated in the mist generating unit 15 is released into the room from the air blowing port 2, and before that, large water droplets enter the air-water separating unit 19 in front of the air blowing port 2. The air / water separator 19 is composed of two baffle plates 20 and 21 that are alternately provided on the opposing walls in the middle of the air passage 17, and the lower first The baffle plate 20 is inclined upward, the upper second baffle plate 21 is inclined downward, and a water droplet holding portion 22 made of a metal mesh or a wire net is bent in a slightly U shape at a tip portion where water droplets collect. The surface tension of the water drop is U-shaped and the contact area is widened to increase the strength, and even a strong wind is prevented from flying off. First, the lower first baffle plate 20 is Inclined upward Therefore, the large water droplets removed from the humidified air without collecting water droplets at the tip part flow down along the inclination of the first baffle plate 20 and travel along the wall surface to which the first baffle plate 20 is attached. The water droplets fall on the way and are quiet without making a popping sound or a popping sound, and the first baffle plate 20 is upward and vigorously pulls upward without being largely restrained by the wind speed. In addition, the humidified air that has passed through the second baffle plate 21 that is inclined upward and downward can suppress the wind speed and remove large drops of water well. Concentrates on the water droplet holding part 22 at the tip part along the second baffle plate 21 inclined downward, but the water drop holding part 22 has a strong surface tension of the water droplets, and does not fly off even in strong winds. It can be used with heart, and the release of large water droplets is surely prevented. The water droplets finally form a large mass that does not fly even with strong winds, fall on the first baffle plate 20 and the water storage chamber 8. The generated nano mist and negative ions are released into the room, so that the room can be cleaned well, and the sucked room air passes through the mist generating part. The room air can be further purified by removing dust and dust, and the indoor environment can be formed in combination with the release of negative ions into the room to obtain a refreshing and refreshing feeling.
