Next, the operation from the start to the end of operation in one embodiment will be described based on the flowchart of FIG.
First, when the operation switch 47 of the operation unit 7 is operated or the operation start time set by the timer on / off switch 49 is reached, the control unit 63 opens the drain valve 36 and the water in the water storage chamber 21. When the water level sensor 30 detects an OFF signal, the water supply pump 32 starts to be driven to drain the water in the water supply pipe 31, and a water replacement mode is performed in which the drain valve 36 is closed when a predetermined time has elapsed ( Step S101).

  When the water replacement mode in step S101 is completed, the control unit 63 supplies the water in the water supply tank 12 into the water storage chamber 21 through the water supply pipe 31, and when a water level sensor 30 detects an ON signal, a predetermined amount of water is supplied.

  When the start-up mode in step S102 is completed, the control unit 63 drives the louver motor 46 to stop the louver 6 at a position perpendicular to the upper surface of the instrument body 1, and is set by the humidification switch 52 and the air volume switch 53. Based on the humidified level and the air flow level, the mist motor control means 64 and the blower fan control means 65 control the respective rotational speeds so that the mist motor 23 and the blower fan 26 are driven at a predetermined rotational speed, By switching the ON / OFF state of the heater 28 based on the detection value of the temperature sensor 29 with the heater control means 66 and controlling it, the water storage temperature in the water storage chamber 21 is determined according to the humidification level and the air flow level. A normal operation mode for executing a mist operation within the temperature range is performed (step S103).

  Here, the normal operation mode will be described in detail. The mist motor control means 64 changes the rotational speed of the mist motor 23 within the range of 800 to 1400 rpm, and the blower fan control means 65 causes the blower fan 26 to fall within the range of 400 to 800 rpm. The mist operation is performed at a rotational speed that matches the air flow level by changing the rotational speed in the interior, and further, the temperature in the water storage chamber 21 is adjusted so that the temperature detected by the blowing temperature sensor 35 becomes a value that matches the humidification level. The water heater temperature is changed, and the heater heater control means 66 switches the ON / OFF state of the heater 28 so that the temperature detected by the water reservoir temperature sensor 29 changes within a range of about 30 to 40 ° C.

  When the operation switch 47 is turned OFF in the middle of the normal operation mode after starting the normal operation mode in step S103 or when the mist operation stop time set by the timer ON / OFF switch 49 is reached, the control unit 63 The louver motor 46 is driven to make the louver 6 stand still in an open state of about 20 ° with respect to the upper surface of the instrument main body 1, the heater 28 is turned on to heat the water, and the water temperature sensor 29 detects the value. The sterilization operation for sterilizing the water in the water storage chamber 21 by switching the ON / OFF state of the heater 28 so that the temperature changes between 63 ° C. and 65 ° C. is executed for 10 minutes, which is a predetermined time, 10 minutes After a lapse of time, a cooling operation for cooling the inside of the water storage chamber 21 is performed, and then a cleaning mode is performed in which the drain valve 36 is opened to drain the water in the water storage chamber 21 (step S10). ).

  When the cleaning mode in step S104 is completed, the control unit 63 causes the mist motor control unit 64 and the blower fan control unit 65 to drive the mist motor 23 and the blower fan 26 at a predetermined number of revolutions for a predetermined period of time. A drying mode is performed to dry the air (step S105). When a predetermined time elapses, the mist motor 23 and the blower fan 26 are stopped to end the drying mode, and the louver motor 46 is driven to close the louver 6. End.

Next, the structure of the back side of the instrument body 1 in this embodiment will be described in detail.
First, as shown in FIG. 7, the support member 16 and the caster 17 on the rear side of the instrument body 1 are installed so as to protrude rearward from a virtual straight line L extending vertically downward from the lower end of the back panel 18. Since the drainage tank 10 and the water supply tank 12 are installed below the instrument body 1, the stability of the instrument body 1 is increased in combination with the center of gravity of the instrument body 1 being downward. Therefore, the risk of falling when the instrument body 1 moves is reduced.

  Further, when the instrument main body 1 is installed at a position where the back side is close to the wall, the support member 16 and the caster 17 on the rear side of the instrument main body 1 are installed so as to protrude from the rear side of the rear panel 18. Since a gap is formed between the panel 18 and the wall, the user can easily perform the ON / OFF switching operation of the breaker 19 and the insertion / extraction operation of the power plug 20 into / from the outlet 68.

  Further, when the instrument main body 1 is installed at a position where the back side is close to the wall, the support member 16 and the caster 17 on the rear side of the instrument main body 1 are installed so as to protrude from the rear side of the rear panel 18. Since a gap is formed between the panel 18 and the wall, the heat generated from the driving components such as the mist motor 23 and the blower fan 26 installed in the instrument body 1 is efficiently radiated from the back side of the instrument body 1. It is possible to prevent the inside of the instrument body 1 from becoming an abnormally high temperature.

  As described above, the drainage tank 10 for storing the water drained from the water storage chamber 21 and the water supply tank 12 for supplying water to the water storage chamber 21 are installed at the lower part of the instrument main body 1, and further, at the bottom of the instrument main body 1. By installing the support member 16 and the caster 17 on the rear side of the instrument body 1 so as to be located behind the rear panel 18, the stability of the instrument body 1 at the time of movement is increased. The risk of falling when moving on slopes can be reduced.

  Further, when the instrument main body 1 is installed so that the back surface is close to the wall, the support member 16 and the caster 17 on the rear side of the instrument main body 1 are installed so as to protrude from the rear of the rear panel 18. Since a gap is formed between the panel 18 and the wall, the instrument body 1 is moved by an ON / OFF operation of the breaker 19 installed on the rear panel 18 and an operation of inserting / removing the power plug 20 from the outlet 68. Since it can be implemented without any problems, the user-friendliness is improved.

  Further, when the instrument main body 1 is installed so that the back surface is close to the wall, the support member 16 and the caster 17 on the rear side of the instrument main body 1 are installed so as to protrude from the rear of the rear panel 18. By forming a gap between the panel 18 and the wall, heat generated from driving parts such as the mist motor 23 and the blower fan 26 in the normal operation mode, and the inside of the water storage chamber 21 during the sterilization operation in the cleaning mode are formed. Since the heater 28 is driven and the heat generated in the state where the water in the water storage chamber 21 is heated to a high temperature can be dissipated from the back side of the instrument body 1, the portion constituting the back side of the instrument body 1 can be radiated. The thermal load can be reduced, and the risk of failure due to the thermal load can be reduced.

  Further, the configuration and control contents in the present embodiment are presented as examples, and are not intended to limit the scope of the invention, and can be implemented in various other forms. Various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
