  The preferred embodiment of the present invention will be briefly described by showing the operation of the present invention.

  The humidifying device of the present invention forms a constant water surface on the humidifying part receiving tray by increasing the amount of water supplied to the humidifying part receiving tray by the water supply means during the humidifying operation from the drainage hole provided in the humidifying section receiving tray. Then, after stopping the humidification operation, the water supply means is stopped and the air blowing means is operated for a predetermined time to dry the humidification section.

  In other words, during the humidifying operation, the amount of water supplied to the humidifying part receptacle is made larger than the amount of water discharged from the drain hole, so that a constant water surface can be formed and water can be supplied to the humidifying part receptacle. After the humidification operation is stopped, the supply of water to the humidifying part tray is stopped and water is discharged from the drain hole of the humidifying part tray, so that no water is left in the humidifying part tray, and further air is sent to the humidifying part by the blowing means. The humidifying part becomes dry.

  Therefore, even when used for a long time or stored for a long time with water in the water tank, the humidification part is in a dry state while the humidification operation is stopped. In addition, the generation of off-flavors can be prevented even during long-term use.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic sectional view showing a humidifying device of the present invention. FIG. 2 is a block diagram showing a control unit of the humidifying device of the present invention, and FIG. 3 is an enlarged schematic cross-sectional view of a main part of the humidifying device of the present invention.

  As shown in FIG. 1, reference numeral 1 denotes a main body of a humidifier. Inside the main body 1 is a humidifier that holds a water tank portion 3 for storing water supplied from a water tank 2 and a vaporization filter 4 as a humidifying portion for evaporating water. It has a part receiving tray 5, a water supply means 6 for supplying water from the water tank section 3 to the humidifying section receiving tray 5, and a drain hole 7 for discharging water from the humidifying section receiving tray 5 to the water tank section 3.

  Further, reference numeral 8 denotes air blowing means for taking in room air from the suction port 9 and blowing the room air to the vaporization filter 4, and releasing the humid air humidified by the vaporization filter 4 from the air outlet 10 provided on the upper surface of the main body 1 into the room. Is.

  FIG. 2 is a block diagram showing the configuration of the control unit, and 11 is a microcomputer (hereinafter referred to as a microcomputer) as the control unit. An operation switch 12 and the like are connected to the input side of the microcomputer 11, and a water supply unit 6 and a blower unit 8 and the like are connected to the output side. The amount of water supplied from the water supply means 6 is set to be larger than the amount of water discharged in advance from the drain hole 7 provided in the humidifying part tray 5 so that a constant water surface is formed on the humidifying part tray 5.

  The operation in the above configuration will be described. When performing the humidification operation, first, water is put into the water tank 2, and this is inserted into the main body 1 and installed at a designated position. As a result, a certain amount of water is stored in the water tank 3 from the water tank 2.

  Next, when the operation switch 12 is turned on, the microcomputer 11 instructs the water supply means 6 to supply water to the humidifying part tray 5, so that the water supply means 6 discharges water from a preset drain hole 7. In order to supply a larger amount of water, a constant water surface is formed in the humidifying part receiving tray 5 after a certain time as shown in FIG. As a result, the vaporizing filter 4 held in the humidifying part receiving tray 5 sucks up and wets water by capillary action.

  Since the microcomputer 11 instructs the air blowing means 8 to drive, the air blowing means 8 takes in the room air from the suction port 9 into the main body 1 of the humidifying device, and the room air is moistened by the water in the humidifying part tray 5. Since it passes through the vaporization filter 4, the humidified air is discharged from the outlet 10 and the humidification operation is performed. Here, the white arrow in FIG. 1 represents the flow of indoor air taken into the main body 1, and the hatched arrow represents the flow of humidified air containing moisture.

  Next, the operation after the operation switch 12 is turned off will be described. When the operation switch 12 is turned off, the microcomputer 11 instructs the water supply means 6 to stop the supply of water to the humidifying part tray 5, so that no water is supplied from the water tank part 3 to the humidifying part tray 5 and the humidifying part tray All the water in 5 is discharged from the drain hole 7 to the water tank 3.

  Further, since the microcomputer 11 gives an instruction to operate the air blowing means 8 for a predetermined time even after the operation switch 12 is turned off, the water remaining in the vaporization filter 4 is vaporized by the room air taken in by the air blowing means 8.

  That is, since the water in the humidifying part receiving tray 5 holding the vaporizing filter 4 is discharged from the drain hole 7 to the water tank part 3, the vaporizing filter 4 cannot suck up the water and moisten the water remaining in the vaporizing filter 4. Since it is dried by the means 8, the vaporization filter 4 is in a dry state while the humidification operation is stopped.

  Therefore, even when the water tank 2 is used for a long time or stored for a long time with water in the water tank 2, the vaporizing filter 4 is in a dry state while the humidifying operation is stopped, so that mold and bacteria propagate on the vaporizing filter 4. Therefore, the generation of a strange odor can be prevented even during long-term use.
