Next, we will explain the operation of the tank device 1.

The flushing water discharged from the water discharge device 4 is used, for example, when the user washes his/her hands, and flows downward from the opening 5b of the washbasin 5. The flushing water that passes through the opening 5b of the washbasin 5 flows into the opening 22 of the inner lid 6 and hits the partition 22b. The flushing water that hits the partition 22b has its momentum reduced and flows into the interior tank 3 through the multiple holes 22c of the partition 22b. In other words, the flushing water whose momentum has been reduced by the partition 22b flows into the interior tank 3. Therefore, the splashing sound that occurs when the flushing water flowing into the interior tank 3 hits the interior tank 3 or the flushing water stored in the interior tank 3 is reduced. In addition, foreign matter contained in the flushing water is collected by the partition 22b.

The cleaning water that hits the partition 22b is prevented from scattering outside the opening 22 by the peripheral wall 22a of the opening 22. In other words, splashing of the cleaning water is prevented. Even if the cleaning water splashes outside the opening 22, the splash prevention section 24 prevents the water from scattering outside the water collection section 23.

Since the water collection section 23 slopes downward toward the opening 22, the washing water that overflows from the opening 22 flows into the opening 22 and into the interior tank 3. The washing water that overflows from the opening 22 is guided by the guide section 25 to the drain outlet 23b, and flows from the drain outlet 23b into the interior tank 3. The washing water that splashes outside the splash prevention section 24 flows into the interior tank 3 from the drain outlet 20a formed in the top plate 20.

Next, the effects of the tank device 1 according to the first embodiment will be explained.

The tank device 1 is a tank device 1 that supplies flush water to the toilet main body. The tank device 1 includes an exterior tank 2, an interior tank 3, a water discharging device 4, a hand washing basin 5, and an inner lid 6.
