  Embodiments of the present invention will be described below with reference to FIGS.

(Embodiment 1)
As shown in FIGS. 1 and 2, the humidifying device according to Embodiment 1 of the present invention has a substantially cylindrical main body case 3 in which an air outlet 1 is formed on the top surface and a suction port 2 is formed in the lower part of the rear side surface. And a water storage container 6 for generating humidified air, a water supply tank 9, a humidifying filter 7 as humidifying means, and a blower 4 for blowing the humidified air into the room.

  As shown in FIG. 2 and FIG. 3, the water storage container 6 is inserted into the lower part of the main body case 3, opens the upper surface, and stores water at a constant water level. The humidification filter 7 is erected by immersing the lower part in the water of the water storage container 6. Further, a water supply tank 9 is inserted from above into a partial opening 6a of a water storage container 6 which is located outside the main body case 3 and has a protrusion 8 protruding upward on the bottom surface. Water is being supplied.

  The water supply tank 9 will be described in more detail. The water supply tank 9 is inserted and removed in a substantially vertical direction along the side surface of the main body case 3, and is a bottle-shaped tank 10 of a size that can be handled with one hand. And a cap 13 that is screwed into a cap mounting cylinder portion 12 projecting downward from a water injection port 11 formed on a bottom surface that is formed at the bottom when the tank 10 is attached to the water storage container 6.

  As shown in FIGS. 3 to 5, the cap 13 includes a cylindrical portion 16 projecting downward from the peripheral edge portion of the communication port 15 into the tank 10 formed on the bottom surface 14 serving as a lid surface, and the cylindrical portion 16. A substantially bowl-shaped valve 18 that opens and closes the communication port 15 is provided, which is fixed to the upper end of a valve shaft 17 that is disposed so as to be movable in the vertical direction.

  The valve shaft 17 is movably held by an annular bearing portion 19 provided concentrically within the cylindrical portion 16, and the bearing portion 19 is a bearing support that connects the outer peripheral surface and the inner peripheral surface of the cylindrical portion 16. By providing a pair of parts 20 on both sides of the cylindrical part 16, the cylindrical parts 16 are provided concentrically.

  Further, when a spring 21 is disposed between the lower end portion of the valve shaft 17 and the bearing portion 19 and urges the valve 18 in a direction to close the communication port 15, and the water supply tank 9 is attached to the water storage container 6. The valve shaft 17 abuts against the protrusion 8 of the water storage container 6 and is pushed up against the tension of the spring 21 to open the valve 18.

  And the cylindrical part 16 forms the notch part 22 in which a part of the lower end part opened downward. The notch 22 has an upper end substantially the same height as the bottom surface 14 of the cap 13.

  That is, the notch 22 is notched to a height from the substantially upper end to the lower end of the cylindrical portion 16, and the height of the cylindrical portion 16 can be kept low.

  In other words, the height of the cylindrical portion 16 is incomplete so that the entire lower end opening edge of the cylindrical portion 16 is not formed on a horizontal plane, that is, the lower end opening surface 16a is partially missing in order to obtain an effect described later. It is sufficient if there is a protruding height at which the notch 22 can be formed so as to form a horizontal plane.

  Furthermore, in order to improve the sealing performance when the valve 18 is closed, a cylindrical valve opening / closing cylinder portion 23 is raised upward from the peripheral portion of the communication port 15 of the bottom surface 14 of the cap 13. 23 is kept low so that the valve 18 is at a height located in the cap mounting cylinder 12 of the tank 10 when closed.

  Thus, the valve opening / closing cylinder part 23 and the cylinder part 16 (below, these two cylinder parts are continuous, and are hereinafter referred to as the cylinder part 16) which are below the valve 18 when the valve 18 is closed are kept low. It becomes height and the internal volume becomes small.

  Moreover, the inner peripheral side corner 22a of the cylindrical portion 16 in the notch 22 is formed in an R-plane shape.

  Further, the notch portion 22 is formed in a direction orthogonal to the direction in which the pair of bearing support portions 20 are provided.

  Since the height of the cylindrical portion 16 is kept low as described above, the valve shaft 17 protrudes downward from the lower end of the cylindrical portion 16, but the cap is formed so as to surround the protruding portion of the valve shaft 17. An outer cylindrical portion 24 is provided so as to be concentric with the cylindrical portion 16 downward from the outer peripheral portion of the bottom surface 14 and longer than the valve shaft 17, and the outer cylindrical portion 24 has an upper end at substantially the same height as the bottom surface 14. Is formed, and an outer notch 25 having an opening at the bottom is formed.

  The bottom surface 14 is formed on an inclined surface 26 that becomes lower from the cylindrical portion 16 side toward the outer cylindrical portion 24. Due to this inclination, the upper end of the outer cutout portion 25 of the outer cylindrical portion 24 is positioned slightly lower than the upper end of the cutout portion 22 of the cylindrical portion 16.

  Next, the operation of the humidifier having the above configuration will be described.

  First, when the water supply tank 9 is filled with water and attached to the water storage container 6, the valve 18 is opened, the water in the tank 10 is supplied to the water storage container 6, and the level of the supplied water is the outer cylindrical portion 24 of the cap 13. When the outer notch 25 reaches the top of the outer notch 25 and is closed by water, the air entering the tank 10 from the communication port 15 through the cylindrical part 16 is cut off, and the water supply is stopped. Stop.

  When the humidifier is operated, the air is blown from the blower 4 to the humidifying filter 7 that has absorbed the water in the water storage container 6, the water absorbed in the humidifying filter 7 is vaporized, and the water in the water storage container 6 gradually decreases. When the water level of the water storage container 6 is slightly lowered from the upper end of the outer notch 25, air enters the cylindrical part 16 from the slightly opened opening of the outer notch 25 and becomes a small bubble. The water enters the tank 10 through the communication port 15, and the water in the tank 10 flows from the cylindrical portion 16 to the water storage container 6 and descends.

  At this time, the air passing through the cylindrical portion 16 as small bubbles is divided into the two flow paths 27a and 27b by the pair of bearing support portions 20 in the bearing portion 19 in the cylindrical portion 16. It passes through the flow path 27 a on the near side facing 22 and reaches the inside of the tank 10. Then, when the air enters the air layer in the tank 10, the water in the tank 10 passes through the cylindrical portion 16 and falls to the water storage container 6. In the cylindrical portion 16, the other flow partitioned by the bearing support portion 20. Even if the internal volume is kept small, the flow path is divided and formed as a flow path through which air and water pass, so that water can be smoothly supplied to the water storage container 6. be able to.

  When the operation is continued, the water in the tank 10 decreases, and when it is almost empty, the water supply tank 9 is lifted in a substantially vertical direction along the side surface of the main body case 3 and removed from the water storage container 6 to replenish water. Carry it to a place where you can and supply water.

  When the water supply tank 9 is lifted in a substantially vertical direction, most of the water that has been filled in the cylindrical portion 16 flows down to the lower storage container 6, and a part of the water in the cylindrical portion 16 below the closed valve 18 is partly dropped. Although water remains, the amount of the remaining water is small because the volume in the cylindrical portion 16 is suppressed to be small.

  And since a part of lower end part of the cylindrical part 16 is notched by the notch part 22 and a part of lower end opening edge is stepped, and a lower end opening edge is not continuously formed on a horizontal surface, it is slightly In the water that remains in the water and reaches the lower end opening edge, no continuous surface tension is generated on the horizontal plane, and the surface tension generated here is smaller than the amount that can balance the weight of the water. When the water is lifted, the water remaining in the cylindrical portion 16 is not retained and immediately falls into the lower water storage container 6.

  Moreover, since the notch 22 has an R-shaped inner peripheral corner 22a of the cylindrical portion 16, the surface tension that tends to hold the water in the R-shaped portion without dropping is weakened. As a result, the falling action of the remaining water is enhanced.

  Further, since the amount of water remaining in the cylindrical portion 16 when the water supply tank 9 is lifted is small as described above, it falls into the water storage container 6 in a very short time.

  Thus, when the water supply tank 9 lifted and taken out from the water storage container 6 is carried to a place where water can be replenished, an amount of water that hangs downward in the cylindrical portion 16 and wets the floor surface does not remain.

  Further, the water supply tank 9 is small and can be easily carried because it can be held with one hand. However, even if the water supply tank 9 is carried without being conscious of preventing the water from dripping, there is no danger of dripping.

  Moreover, even if the water supply tank 9 is a small humidifier placed on a desk, it is possible to prevent documents on the desk from getting wet when water is supplied to the water supply tank 9.

  And in order to show | play the above-mentioned effect, the protrusion height from the bottom face 14 of the cylindrical part 16 breaks the phenomenon in which the surface tension of water and the weight of water balance and hold without falling. If the notch 22 which can be formed is formed, it is sufficient.

  Further, since the bottom surface 14 of the cap 13 is formed on an inclined surface 26 that becomes lower from the cylindrical portion 16 side toward the outer cylindrical portion 24, it adheres to the bottom surface 14 when the water supply tank 9 is lifted from the water storage container 6. The flowing water is guided to the inclination and flows to the outer cylindrical portion 24 side, and immediately flows down from the outer cylindrical portion 24 to the water storage container 6.

  Therefore, in the process of lifting the water supply tank 9, even if an amount of water that hangs down is carried on the bottom surface 14 of the cap 13 as it is, the attached water can be immediately dropped into the water storage container 6 before the carrying operation.

  In this way, it is possible to eliminate the risk of water dripping from the bottom surface 14 of the cap 13 while the water supply tank 9 is being carried.

  Since the outer cylindrical portion 24 is provided around the valve shaft 17 protruding from the cylindrical portion 16, when carrying the water supply tank 9, the valve shaft 17 is accidentally applied to the tip of the valve shaft 17. It is possible to reliably prevent the shaft 17 from being pushed and the water in the tank 10 from leaking. Further, when the water supply tank 9 replenished with water is once placed on a sink or the like, the outer cylindrical portion 24 can be placed on the lower side.

  In the first embodiment, a small humidifier is described in which the water supply tank can be held and carried with one hand. However, the size of the humidifier is not limited, and the cylindrical portion below the valve of the cap is provided with water supply. When the tank is taken out from the water storage container, the same effect can be obtained as long as water has a volume that remains due to surface tension.

  Also, a vaporizing type with a humidifying filter is used as a humidifying means, but water is broken finely by ultrasonic vibration and blown by a blower, or steam is generated by heating water with a heater. The heating method may be used, and the humidification method is not limited to the humidification method.

  Further, the bottom surface 14A of the cap 13A is a horizontal plane without being inclined.

  With the above configuration, even if the water supply tank 9A is lifted so that the cap 13A is pulled up from the water surface of the water storage container 6 in a substantially vertical direction, the lower end opening edge of the cylindrical portion 16A is always located on the inclined surface. There is no surface tension of water that can balance the weight of water at the edges.

  As described above, in the humidifying device according to the second embodiment, when the water supply tank 9A is taken out of the water storage container 6, the water in the cylindrical portion 16A of the cap 13A is not inclined and lifted so as to drop into the water storage container 6. The water in the cylindrical portion 16A can be dropped into the water storage container 6 before carrying the water supply tank 9A.

It is characterized in that it is formed on the lower inclined surface 26A, and the outer cylindrical portion 24 in the first embodiment is not provided.

  With the above configuration, the water adhering to the bottom surface 14B of the cap 13B is guided by the inclination of the inclined surface 26A, flows from the outer peripheral portion to the cylindrical portion 16 side, immediately flows down from the cylindrical portion 16 to the water storage container 6, and carries the water supply tank 9B. The risk of water dripping from the bottom surface 14B of the cap 13B can be eliminated.

  Moreover, since the cap 13B does not have the outer cylindrical portion 24, the portion to which water adheres can be reduced.

(Embodiment 4)
As shown in FIGS. 12 and 13, the humidifying device according to the fourth embodiment of the present invention is configured so that the bottom surface 14 </ b> C of the cap 13 </ b> C extends from the one side end to the one side end with respect to the humidifying device according to the first embodiment. This is characterized in that the inclined surface 26B is inclined toward the side end facing the portion.

  With the above configuration, when the water supply tank 9C is lifted from the water storage container 6 (not shown), the water adhering to the bottom surface 14C of the cap 13C is inclined by the slope extending from one side end of the bottom surface 14C to the opposite side end. Then, it flows uniformly in the same direction in the bottom surface 14C, and immediately flows down from the wall surface portion of the outer cylindrical portion 24 located at the lowest part of the bottom surface 14C to the water storage container.

  As described above, according to the humidifying device of the fourth embodiment, when the water supply tank 9C is taken out of the water storage container 6, even if an amount of water dripping during carrying is attached to the bottom surface 14C of the cap 13C, Flows smoothly through the bottom surface 14C and can be dropped into the water storage container.
