61 is an overflow pipe one end of which is connected to the wall surface of the water storage chamber 8. Should the water level sensor 21 malfunction and the water level cannot be detected, the water supply from the water supply pipe 22 will not be stopped and the water level of the water storage chamber 8 will rise. Even if it rises abnormally, the water in the water storage chamber 8 can be drained through the overflow pipe 61 .
A throttle mechanism 62 is connected to the other end of the overflow pipe 61 to reduce the inner diameter of the overflow pipe 61 to reduce the flow path.

The drain pipe 64 leads to a drain hopper 65 installed outside the instrument body 1 for draining water from the drain pipe 25b. The outlet side of the drainage pipe 64 is not directly connected to the drainage hopper 65 because the drainage hopper 65 may flow backward if it is directly connected to the drainage hopper 65 .

Next, operations from the start to the end of operation in this embodiment will be described based on the flow chart of FIG.
First, when the operation switch 30 of the operation unit 6 is operated or when the operation start time set by the timer switch 33 is reached, the control unit 45 opens the drain valve 26 to drain the water in the water storage chamber 8. When an OFF signal is detected by the water level sensor 21, the water supply valve 23 is opened to perform a cleaning operation to wash the inside of the water storage chamber 8 with water. When the ON signal is detected by the water level sensor 21, a predetermined amount of water has been supplied to the water storage chamber 8 and the water supply valve 23 is closed (step S101). ).

After the water replacement mode in step S101 is finished, the controller 45 turns on the heater 19 by the heater control means 48 until the temperature of the stored water detected by the stored water temperature sensor 20 becomes the same as the room temperature. Then, a start-up mode is performed in which a start-up operation controlled by the mist motor control means 46 and the blow fan control means 47 is performed so that the blower fan 14 reaches a predetermined rotational speed (step S102).

After the start-up mode of step S102 ends, the controller 45 causes the mist motor 11 and the blower fan 14 to rotate at a predetermined number of revolutions based on the humidification level and the air volume level set by the humidification switch 31 and the air volume switch 32. The rotation speed is controlled by the mist motor control means 46 and the blower fan control means 47 so as to be driven, and the ON/OFF state of the heater 19 is switched and controlled by the heater control means 48 to control the humidification level and the air volume level. A normal operation mode is performed in which a mist operation is performed to keep the combined temperature within a predetermined range (step S103).

When it is determined that the operation switch 30 has been operated during the normal operation mode in step S103 and an instruction to end the operation has been issued, the control unit 45 stops the mist motor 11 and then opens the drain valve 26 to After the water is drained, the water supply valve 23 is opened after a predetermined period of time has elapsed, the inside of the water storage chamber 8 is washed, the drain valve 26 is closed, and a water replacement operation is performed in which a predetermined amount of water is stored in the water storage chamber 8, and then, A sterilization operation is performed for a predetermined period of time to sterilize the water by turning on the heater 19 and heating the water. When it becomes below, the cleaning mode is performed in which the drain valve 26 is opened to drain the water (step S104).

After the cleaning mode in step S104 is finished, the control unit 45 controls the blower fan control means 47 so that the blower fan 14 is driven at a predetermined number of revolutions (800 rpm, for example), and blows air into the water storage chamber 8 and the blower path 15. A drying mode is performed to prevent the growth of bacteria by drying the air with the air (step S105). to stop the operation.

Next, the flow paths of dry air and humidified air during mist operation will be described with reference to FIG.

First, when the mist operation is started and the mist motor 11 and the blower fan 14 are driven at a predetermined number of revolutions, indoor air is sucked through the suction ports 49 on the bottom surface and the front surface of the appliance main body 1 .
Then, the sucked air rises through the blowing path 15 and is divided into air flowing into the water storage chamber inlet 16 and air heading for the bypass inlet 51 via the bypass path 50 .

The air flowing into the water storage chamber 8 from the water storage chamber inlet 16 is pumped up by the rotating body 10 and crushed by the porous portion 13 to be humidified air containing fine mist, large-diameter mist, and negative ions. Climb through the separated air passage 17 . In addition, since the humidified air is heated by the heater 19, the humidified air has a higher temperature than the room temperature.
When the air-water separation air passage 17 rises, the passage meanders due to the baffle plates 18a, 18b, and 18c, and circulates so as to lick the inclined surface of each baffle plate 18, whereby large-diameter mist in the humidified air flows into each baffle. When the droplets adhere to the surface of the plate 18 and reach the lower end of each inclined baffle plate 18, the water droplets drop into the water storage chamber 8 due to gravity, so that the amount of large-diameter mist carried to the blower port 2 can be reduced.

On the other hand, the air diverted to the bypass route 50 flows through the bypass route 50 and then into the air-water separation air passage 17 via the bypass inlet 51 .
Then, the humidified air rising from the water storage chamber 8 through the air-water separation air passage 17 and the air branched in the bypass passage 50 and flowed in from the bypass inlet 51 were connected to the downstream end of the air-water separation air passage 17. Mix in the head space 52 .
A guide plate and a rectifying plate (not shown) installed in the upper space 52 guide the humidified air toward the air outlet 2 and supply the humidified air containing fine mist and negative ions into the room.

Next, the effect of preventing the whistling sound generated near the outlet of the drain pipe 64 by providing the throttle mechanism 62 for reducing the inner diameter of the overflow pipe 61 will be described with reference to FIGS. 7 and 8. FIG.

Please refer to FIG. When the mist motor 11 and the blower fan 14 are driven during the mist operation, indoor air is sucked from the suction port 49, passes through the airflow path described above, and is blown from the blower port 2 as humidified air. Air also flows into the overflow pipe 61 connected to the inner wall surface. In other words, after the air that has flowed through the overflow pipe 61 reaches the joint 63, it does not flow to the drain pipe 25a because the drain valve 26 is closed. end) is for indirect drainage and is open to the outside air.

At this time, if the drain pipe 64 has a bellows tube structure like a flexible pipe and the flow speed of the air is high, resonance occurs in the drain pipe 64 and a whistling sound is generated from the outlet side of the drain pipe 64. It's easy to do. The whistling sound is noise generated by a resonance phenomenon or the like caused by the corrugated shape of the flexible pipe, and may make the user feel uncomfortable.

Therefore, as shown in FIG. 8, a throttle mechanism 62 is provided between the overflow pipe 61 and the joint 63, and the inner diameter φd1 of the overflow pipe 61 is reduced to the inner diameter φd2 by the throttle mechanism 62. Since the wind speed of the air flowing through the drain pipe 64 can be reduced, the occurrence of whistling noise on the outlet side of the drain pipe 64 can be prevented. The size of the inner diameter φd2 throttled by the throttle mechanism 62 is such that even if the water level in the water storage chamber 8 rises abnormally due to a malfunction of the water level sensor 21 and overflow occurs, the flow rate that can be drained from the overflow pipe 61 without problems is ensured. It's big enough to do.

Next, the effect of suppressing the generation of biofilm (microorganisms) by arranging the throttle mechanism 62 in the immediate vicinity of the joint 63 will be described with reference to FIGS. 7 and 8. FIG.

In order to prevent the generation of the whistling sound, it is necessary to reduce the wind speed of the air flowing through the overflow pipe 61 and the drain pipe 64, so a method of reducing the inner diameter with the throttle mechanism 62 is described. On the other hand, in order to suppress the effects of biofilms generated in water pipes, it is necessary to increase the inner diameter of the pipes so that the pipes are not clogged by biofilms. are in a trade-off relationship.
Here, the throttling portion of the inner diameter φd2 in the throttling mechanism 62 is smaller in diameter than the inner diameter φd1 of the overflow pipe 61, and the throttling mechanism 62 is more likely to generate biofilm than the overflow pipe 61. .

On the other hand, when the operation switch 30 is operated during the mist operation and the operation ends, the control unit 45 opens the drain valve 26 to drain the water in the water storage chamber 8 . The stored water temperature at this time is as high as about 60° C. because the operation has just stopped. In the drainage path, the water flows through the drainage pipe 25a, the joint 63, the drainage pipe 25b, and the drainage pipe 64, and then is discharged to the drainage hopper 65 for drainage treatment.

Therefore, by arranging the throttle mechanism 62, where biofilm is likely to occur, close to the joint 63, the heat associated with the drainage is applied to the throttle mechanism 62 at the timing of the end of the operation. biofilm can be suppressed.

In addition, since the whistling sound can be prevented by narrowing the inner diameter to φd2 with the throttle mechanism 62, the inner diameter φd1 of the overflow pipe 61 can be increased, so that the influence of the biofilm generated in the overflow pipe 61 can be suppressed. can do.

As described above, by arranging the throttling mechanism 62 in the drainage path of the overflow pipe 61, the wind speed of the air flowing through is reduced while ensuring the drainage flow rate at the time of overflow occurrence, and the whistling sound at the outlet side of the drainage pipe 64 is reduced. can be prevented from occurring. Furthermore, by arranging the throttle mechanism 62 in the immediate vicinity of the joint 63, biofilms generated in the throttle mechanism 62 due to the heat associated with the drainage of the water storage chamber 8 can be suppressed. In other words, it is possible to simultaneously achieve the prevention of whistling noise generation and the suppression of biofilm generation, which are in a trade-off relationship, thereby avoiding discomfort for the user.

In this embodiment, the throttling mechanism 62 has an orifice structure in which the overflow tube 61 is contracted and then expanded.

Further, in the present embodiment, the water in the water storage chamber 8 is pumped up by rotationally driving the rotating body 10, and the nano-mist and negative ions generated by crushing the porous portion 13 are released into the room as humidified air. Although the humidifier has been described, the humidifier may be a vaporization type humidifier that discharges humidified air into the room by blowing air to a filter containing water.

In addition, other configurations used in the present embodiment are presented as an example, 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 description. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and equivalents thereof.
