The operation of supplying water to the water storage container 10 with the above configuration of the tank unit 2 will be described. First, when the handle 23 of the tank portion 2 containing water is attached to the tank attaching portion 6, the columnar protrusion (not shown) provided on the inner surface of the bottom plate of the water storage container 10 is spring-loaded as the valve mechanism 29. The portion 40 hits, and the spring stop portion 40 moves upward while compressing the spring 39. (See FIG. 9) Along with this, the on-off valve portion 38 also rises, and the on-off valve portion 38, which is the valve mechanism 29, separates from the lid opening 28 of the lid 22, so that water in the tank 20 flows from the lid opening 28 of the lid 22. It flows into the water storage container 10. Here, when water is stored in the water storage container 10 up to the lower end of the circumferential wall around the valve mechanism 29 that opens and closes the lid opening 28, air may enter the tank 20 from the lower end of the circumferential wall 31 around the valve mechanism 29. Since there is no water, the water in the tank 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, and the water level is kept constant at the lower end of the circumferential wall 31.

The feature of this embodiment is that a water drip promoting portion 41 is provided at the opening edge of the first hole 32 of the lid 22, as shown in FIGS. As a result, water can be easily dropped from the first hole 32, air can be easily introduced from the second hole 33, a sound generated during water supply can be suppressed, and water can be easily discharged.

Specifically, the water drip promoting portion 41 projects downward from the outer side of the lower end opening edge of the first hole 32 in the lid 22 in a state where the lid 22 of the tank portion 2 is attached to the water storage container 10. It is a protrusion. The projection is entirely projected on the outer side of the lower end opening edge of the first hole 32, and is projected downward without a step with the first hole 32. That is, the protrusion projects downward along the outer side of the lower end opening edge of the first hole 32, which is a C-shaped hole, and has a horizontal cross-sectional shape of C-shape. The hole inner surface 43 on the outer side of the first hole 32 and the protrusion inner surface 44 are connected without a step.

As a result, in the first hole 32, a water surface is formed at the lower end opening of the first hole 32 along the inner opening edge of the first hole 32 and the lower end of the protrusion, and in the second hole 33, A water surface is formed at the lower end opening of the second hole 33. It is considered that the water surface of the first hole 32 is located below the water surface of the second hole 33, and the water surface is formed with an inclination with respect to the lid surface portion 25. As a result, the balance between the first hole 32 and the second hole 33 is lost, and the water surface formed in the first hole 32 is below the second hole 33. It is considered that the water easily flows into the water storage container 10 through the hole 32 of No. 1.

Further, the air entry promoting portion 42 is provided at the opening edge of the second hole 33 of the lid 22. As a result, water is likely to drip from the first hole 32, air is more likely to enter from the second hole 33, the sound generated at the time of water supply is suppressed, and water can be easily discharged.

Specifically, the air entry promoting portion 42 is a recess that is recessed into the tank 20 from the outside of the lower end opening edge of the second hole 33 in the lid 22. As for the depression, the entire outer side of the lower end opening edge of the second hole 33 is recessed into the tank 20, and there is no step on the lower end opening edge of the second hole 33, and the recess is formed on the outer side wall of the second hole 33. It is a shape that connects at an angle. In other words, the depression is a C surface in which the corner on the outer side of the lower end opening edge of the second hole 33 is chamfered.

As a result, the water surface formed in the second hole 33 is located at the inner opening edge of the second hole 33, the edge of the second hole 33 and the air entry promoting portion 42, and the water surface formed in the first hole 32. It is considered that it is formed above the formed water surface with an inclination with respect to the lid surface portion 25. As a result, the balance between the first hole 32 and the second hole 33 is lost, and the water surface formed in the first hole 32 is below the second hole 33. It is considered that the water easily flows into the water storage container 10 through the hole 32 of No. 1. Further, by providing the air invasion promoting portion 42, the opening at the lower end of the second hole 33 is widened, and it becomes easier for air to enter the tank 20 from the water storage container 10 through the second hole 33.
