Some of them switch each mode according to the detected indoor humidity or the humidification mode selected by the user. (For example, Patent Document 1)

In addition, in a vaporization type humidifier that blows humidified air by blowing air to a filter installed in the water storage room, a constant current value is applied to the electrodes installed in the water storage room to apply a constant concentration of metal ions to the water.

(Explanation of a series of driving operations)
Next, the operation from the start to the end of the operation in this embodiment will be described.
See FIG. First, when the operation switch 70 of the operation unit 6 is operated, the control unit 80 opens the drain valve 51 to drain the water in the water storage chamber 10. When the water level sensor 32 detects an OFF signal, the water supply valve 41 is opened to perform a cleaning operation of flushing the inside of the water storage chamber 10 with water, and the drain valve 51 is closed after a predetermined time has elapsed. After closing the drain valve, a constant current is applied to the electrode 46 in the ion elution unit 43 to elute silver ions, and water containing silver ions flows into the water storage chamber 10 through the water supply pipe 40. Then, when the ON signal is detected by the water level sensor 32, the water supply valve 41 is closed assuming that a predetermined amount of water has been supplied into the water storage chamber 10, and a water replacement mode for stopping the application of a constant current to the electrode 46 is performed ( Step S101).

When the water replacement mode in step S101 is completed, the control unit 80 turns on the heater 30 with the heater control means 83 until the water storage temperature detected by the water storage temperature sensor 31 becomes equal to the room temperature, and the mist motor 13 And the start-up mode for executing the start-up operation controlled by the mist motor control means 81 and the blower fan control means 82 so that the blower fan 20 has a predetermined rotation speed is performed (step S102).

When the start-up mode of step S102 is completed, the control unit 80 and the mist motor control means 81 so that the mist motor 13 and the blower fan 20 are driven at a predetermined rotation speed based on the set humidification level and air volume level. The rotation speed is controlled by the blower fan control means 82, and the ON / OFF state of the heater 30 is switched and controlled by the heater control means 83 to keep the temperature within a predetermined temperature range according to the humidification level and the air volume level. The normal operation mode for executing the mist operation is performed (step S103).

In this normal operation mode, when the water level in the water storage chamber 10 drops and the water level sensor 32 detects an OFF signal, the control unit 80 opens the water supply valve 41 and determines the electrode 46 in the ion elution unit 43. A constant current value is applied to supply water containing silver ions having a predetermined concentration into the water storage chamber 10. As a result, the antibacterial action on the water in the water storage chamber 10 works, and the occurrence of slime around the water storage chamber 10 can be suppressed.

When the operation switch 70 is operated during the normal operation mode of step S103 and an instruction to end the operation is given, or it is determined that the predetermined operation continuation time has elapsed, the control unit 80 stops the mist motor 13 and then presses the drain valve 51. After opening the valve to drain the water in the water storage chamber 10, the water supply valve 41 is opened after a predetermined time has passed, and a constant current is applied to the electrode 46 in the ion elution unit 43 to clean the inside of the water storage chamber 10. A water replacement operation is performed in which the drain valve 51 is closed and a predetermined amount of water is stored in the water storage chamber 10.
After that, a sterilization operation for sterilizing water by heating the water with the heating heater 30 turned on is performed for a predetermined time, and after a predetermined time elapses, a cooling operation for cooling the inside of the water storage chamber 10 is executed, and the water storage temperature becomes a predetermined temperature. When the following occurs, the drain valve 51 is opened to perform a cleaning mode for draining water (step S104).

When the cleaning mode in step S104 is completed, the control unit 80 controls the blower fan 20 to be driven at a predetermined rotation speed (for example, 800 rpm) by the blower fan control means 82, and blows air to the water storage chamber 10 and the blower path 21. A drying mode is performed to prevent the growth of bacteria by drying (step S105), it is determined whether the driving time of the blower fan 20 has counted a predetermined time (for example, 3 hours), and after counting for 3 hours, the blower fan 20 To stop the operation.

(Explanation of control contents at each humidification level and air volume level)
Next, the control contents at each humidification level and air volume level during the mist operation will be described.
See FIG. 7. In the state of humidification level 1, the heating heater 30 is always turned off to not heat the water in the water storage chamber 10, and in the state of humidification level 2, the ventilation temperature detected by the ventilation temperature sensor 60 is the intake air temperature sensor. The ON / OFF state of the heater 30 is switched so that the value obtained by subtracting the first predetermined value (here, 2 ° C.) from the intake air temperature detected by 61 is switched, and in the state of humidification level 3, the blower temperature sensor 60 detects it. The ON / OFF state of the heater 30 is switched so that the blown air temperature to be blown becomes a value obtained by adding a second predetermined value (here, 1 ° C.) to the intake air temperature detected by the intake air temperature sensor 61.

By controlling the humidification level, the ventilation temperature rises as the humidification level rises, and the proportion of water contained in the humidified air generated in the water storage chamber 10 increases. Can be adjusted. Therefore, when the humidification level is set to the auto mode, the indoor humidity is maintained near a predetermined humidity (here, 50% RH) by changing the humidification level according to the humidity detected by the humidity sensor 62. Can be done.

When the humidification level is set to the auto mode, the specific control content is that if the humidity detected by the humidity sensor 62 is less than 40% RH, the humidification level is set to 3 and 40% RH or more and 60%. If it is in the range of RH or less, the humidification level is set to 2, and if it exceeds 60% RH, the humidification level is set to 1.

Furthermore, since the ON / OFF state of the heating heater 30 is switched so that the air blowing temperature is close to the intake air temperature, the humidity can be changed without significantly changing the indoor temperature, so that hot air or cold air hits the user. Does not cause discomfort.

That is, the humidification level 1 is a mode without a heater, and the humidification levels 2 and 3 are modes with a heater.

Further, the control of the air volume level will be described in detail. In the state of the air volume level 1, the mist motor 13 is driven at a rotation speed of 400 rpm and the blower fan 20 is driven at a rotation speed of 1000 rpm, and in the state of the air volume level 2, the mist motor 13 is driven at 600 rpm and the blower fan. 20 is driven at a rotation speed of 1200 rpm, and in the state of air volume level 3, the mist motor 13 is driven at a rotation speed of 800 rpm and the blower fan 20 is driven at a rotation speed of 1400 rpm.

By controlling the air volume level, when the air volume level rises, the humidification amount of the humidified air blown into the room increases, and the humidity in the room can be increased. Therefore, the humidification amount in the room to be humidified can be adjusted. Therefore, when the air volume level is set to the auto mode, the indoor humidity is maintained near a predetermined humidity (here, 50% RH) by changing the air volume level according to the humidity detected by the humidity sensor 62. Can be done.

When the air volume level is set to the auto mode, the specific control content is that if the humidity detected by the humidity sensor 62 is less than 40% RH, the air volume level is set to 3 and 40% RH or more and 60%. If it is in the range of RH or less, the air volume level is set to 2, and if it exceeds 60% RH, the air volume level is set to 1.

(Explanation of the decreasing tendency of silver ion concentration)
Next, the decreasing tendency of the silver ion concentration at each humidification level during the mist operation will be described.
The applicant has set the humidification level 1 for fixing the heating heater 30 in the OFF state and the humidification level 2 or 3 for switching the ON / OFF state of the heating heater 30 with the same silver ion concentration in the water storage chamber 10. The air volume levels were fixed at the same value for comparison. As a result, the applicant has found that the silver ion concentration in the water storage chamber 10 after a predetermined elapsed time is lower at the humidification level 2 or 3 than at the humidification level 1.

See FIG. Therefore, when the humidification level 1 is set during the mist operation, the constant current value applied to the electrode 46 is set to 12 mA, which is a predetermined current value, and the silver ion concentration of the water supplied into the water storage chamber 10 is 0.22 ppm. When the humidification level 2 or 3 was set, the constant current value applied to the electrode 46 was set to 14 mA, and the silver ion concentration of the water supplied into the water storage chamber 10 was set to 0.25 ppm. As a result, water having a higher silver ion concentration is supplied to the water storage chamber 10 when the humidification level 2 or 3 is set than when the humidification level 1 is set. Therefore, silver ions in the water storage chamber 10 are supplied. Regardless of the humidification level set for the concentration, it can be maintained at the target predetermined value.

(Explanation of water supply operation during mist operation)
Next, the water supply operation during the mist operation in step S103 will be described.
See FIG. After transitioning from step S102 to step S103 and starting mist operation, the control unit 80 determines whether the water storage chamber 10 is at the water supply start water level with the detection result of the water level sensor 32 OFF (S201), and water supply is started. When it is determined that the starting water level has been reached, the water supply valve 41 is opened and water supply into the water storage chamber 10 is started (S202).

When the water supply to the water storage chamber 10 is started in step S202, the control unit 80 determines whether the currently set humidification level is 1 (S203), and if the humidification level 1 is set, the concentration variable means. The constant current value applied to the electrode 46 by 84 is set to 12 mA and the application is started (S204), and if the humidification level is set to 2 or 3, the constant current applied to the electrode 46 by the concentration variable means 84 is set. The value is set to 14 mA and the application is started (S205).

When a predetermined constant current value is applied to the electrode 46 in step S204 or step S205, the control unit 80 determines whether the detection result of the water level sensor 32 is switched to the ON state and the water supply stop water level of the water storage chamber 10 is reached. (S206) When it is determined that the water supply stop water level is reached, the water supply valve 41 is closed to stop the water supply into the water storage chamber 10, and the application of the constant current value to the electrode 46 is stopped (S207). ..

Further, if the detection result of the water level sensor 32 in step S206 is still in the OFF state and the water supply stop water level is not reached, the control unit 80 repeats the determination in step S203.

If the detection result of the water level sensor 32 in step S201 was not the water supply start water level in the ON state, or if the process in step S207 was completed, the control unit 80 determined whether the operation switch 70 was operated or the predetermined operation duration. Has passed and it is determined whether the operation end instruction has been issued (S208), and when it is determined that the operation end instruction has been issued, the normal operation mode is changed to the cleaning mode of S104 to end the mist operation, and the operation end instruction is issued. If it is determined that the determination has not been made, the determination in S101 is repeated.

In this way, by varying the constant current value applied to the electrode 46 according to the set humidification level, the silver of the water supplied into the water storage chamber 10 according to the presence or absence of heating of the water in the water storage chamber 10. Since the ion concentration can be adjusted and the silver ion concentration of the water in the water storage chamber 10 can be maintained at the target predetermined value regardless of whether the water is heated or not, the occurrence of slime around the water storage chamber 10 can be surely suppressed. Can be done.

Next, the effect of this embodiment will be described.

When humidification level 2 or 3 is set, which is a mode with a heater that drives the heater 30 that heats the water in the water storage chamber 10, and when humidification level 1 is set, which is a mode without a heater that does not drive the heater 30. Since the concentration of silver ions eluted into the water is increased by the concentration variable means 84, even when the water in the water storage chamber 10 is heated, the inside of the water storage chamber 10 is maintained at the target silver ion concentration. Therefore, it is possible to reliably suppress the occurrence of sliminess in the vicinity of the water storage chamber 10 regardless of whether or not the water is heated.

Further, the electrode 46 is installed in the middle of the water supply pipe 40 which is connected to the water storage chamber 10 and supplies water, and the concentration variable means 84 is the silver ion concentration contained in the water supplied from the water supply pipe 40 into the water storage chamber 10. Since the concentration of silver ions contained in the water in the water storage chamber 10 is adjusted by varying the above, the flow rate of the water passing through the water supply pipe 40 is constant, so that it is included in the water supplied into the water storage chamber 10. Since the silver ion concentration in the water storage chamber 10 can be easily adjusted and the silver ion concentration in the water storage chamber 10 can be maintained at a target predetermined value, the occurrence of slime in the vicinity of the water storage chamber 10 is surely suppressed regardless of whether or not the water is heated. can do.

Further, the concentration variable means 84 adjusts the concentration of silver ions contained in the water in the water storage chamber 10 by changing a predetermined current value applied to the electrode 46, and the control unit 80 moves into the water storage chamber 10. When the humidification level 2 or 3 is set at the time of water supply, the predetermined current value applied to the electrode 46 by the concentration variable means 84 is increased as compared with the case where the humidification level 1 is set, so that the water storage chamber 10 Since the concentration of silver ions contained in the water supplied to the inside can be easily adjusted and the concentration of silver ions in the water storage chamber 10 can be maintained at a target predetermined value, the vicinity of the water storage chamber 10 regardless of whether the water is heated or not. It is possible to surely suppress the occurrence of slime.

The humidified air generating means includes a tubular rotating body 12 whose lower end is submerged in the water storage chamber 10 and water is pumped up and scattered by rotation, a mist motor 13 which rotationally drives the rotating body 12, and rotation of the rotating body 12. Since it is composed of a perforated portion 15 with which the scattered water collides, in order to effectively disperse the water containing silver ions around the water storage chamber 10, the vicinity of the water storage chamber 10 regardless of whether the water is heated or not. It is possible to surely suppress the occurrence of slime.
