  The operation of supplying water to the water storage container 10 in the configuration of the tank unit 2 will be described. First, when the handle 23 of the tank part 2 containing water is held and attached to the tank attaching part 6, a spring-restraining that is a valve mechanism 29 is provided on a cylindrical protrusion (not shown) provided on the inner surface of the bottom plate of the water storage container 10. The part 40 hits, and the spring stopper 40 moves upward while contracting the spring 39. (See FIG. 9) Accordingly, the opening / closing valve portion 38 also rises, and the opening / closing valve portion 38 that is the valve mechanism 29 is separated from the lid opening 28 on the tank 20 side (upper side) of the lid 22, whereby the lid opening 28 of the lid 22. As the air enters the tank 20 from the water, the water in the tank 20 drops into the water storage container 10. Here, when water is accumulated in the water storage container 10 up to the lower end of the circumferential wall 31 around the valve mechanism 29 that opens and closes the lid opening 28, air enters the tank 20 from the lower end of the circumferential wall 31 around the valve mechanism 29. Therefore, the water in the tank 20 does not flow into the water storage container 10. That is, when the water in the water storage container 10 decreases, the water level increases to the lower end of the circumferential wall 31 around the valve mechanism 29, and the water level is kept constant at the lower end of the circumferential wall 31.

  As shown in FIGS. 7, 8, and 9, the present embodiment is characterized in that the center axis of the cylinder 28 a is inclined with respect to the vertical direction in a state where the tank unit 20 is mounted on the water storage container 10.

  When the water in the tank 20 drops into the water storage container 10, air enters the tank 20 from the lower end of the circumferential wall 31 through the lid opening 28, but the air is trapped between the on-off valve portion 38 and the valve support 30. In some cases, this air pool prevents air from entering the tank 20 and makes it difficult for water to drip. In such a case, the lower surface of the on-off valve portion 38 is also inclined because the central axis of the cylinder portion is inclined with respect to the vertical direction. Part of the air that has entered between the on-off valve portion 38 and the valve support 30 rises upward along the inclination of the lower surface of the on-off valve portion 38, and easily enters the tank 20. As a result, since the air reservoir easily enters the tank 20 from the lid opening 28 due to the inclination of the central axis without increasing the lid opening 28, the sound generated during water supply is suppressed, and water can easily drip from the lid opening. Become.

  Further, the valve support 30 has a crosspiece 34 arranged perpendicularly to the central axis of the cylinder 28 a and on a horizontal plane, and the first hole 32 is located above the second hole 33. The lid surface portion 25 is also inclined so that the first hole 32 side is positioned above the second hole 33 side.

  As a result, air that has entered from the lower end of the circumferential wall 31 is likely to accumulate in the vicinity of the first hole 32 on the lower surface of the lid surface portion 25. In this state, when air enters from the lower end of the circumferential wall 31, the air accumulated in the vicinity of the first hole 32 easily enters from the first hole 32. As a result, air enters the tank 20 from the first hole 32, and the water in the tank 20 easily flows out to the water storage container 10 from the second hole 33, and between the open / close valve portion 38 and the upper end of the cylinder 28a. It becomes difficult to collect air.

  The air conditioner according to the present invention is useful as a humidifier used for home use or office use.
