The sterilization is sequentially performed by the first sterilization apparatus 31, the second sterilization apparatus 33, and the third sterilization apparatus 35 while sequentially passing through the three storage spaces 28.

On the other hand, the high water level sensor 41, the medium water level sensor 43, and the low water level sensor 45 are installed on the side walls of the third storage space 28, respectively. The controller not shown controls the flow path control means (not shown) such as a valve or a pump connected to the third sterilizer 35 and the water inlet 15 by receiving the water level information from the water level sensors 41, 43, and 45. .

That is, the controller controls the flow path control means to receive water through the water inlet 15 when the water level of the third storage space 28 is below the low water level. When water is supplied through the water inlet 15, water enters the third storage space 28 through the first storage space 21 and the second storage space 25, and the water level rises. At this time, the output of the third sterilizer 35 installed in the third storage space 28 is set low (steps 1, 2, and 3 of FIG. 6).

When the water level rises above the heavy water level, water is continuously supplied through the water inlet 15, but the output of the third sterilizer 35 installed in the third storage space 28 is adjusted to be high. step)

When the water level continues to rise to reach a high water level, the output of the third sterilizer 35 is maintained at a high state and the water supplied through the water inlet 15 is shut off using the flow path control means. )

When the user discharges water from the third storage space 28 using water, the water level is lowered. When the water level falls below the medium water level, the output of the third sterilizer 35 is changed again to a low state, and the water blocking state is maintained.

Finally, when the water level falls below the low water level, water is supplied from the water inlet 15 while the output of the third sterilizer 35 is kept low.

In the storage tank 10 according to the present invention, the output of the third sterilizer 35 is adjusted according to the water level stored in the third storage space 28. Therefore, since the amount of power supplied to the sterilizers 31, 33, 35 is adjusted according to the amount of stored water, it is possible to prevent the power consumption.

In addition, since the storage tank 10 is sterilized by dividing the storage tank 10 into several storage spaces 21, 25, and 28 in a step-by-step manner, even when water is stored in the storage tank 10 for a long time, sufficient sterilization effect is achieved. You will get it.

In this embodiment, three storage spaces (21, 25, 28), three sterilizers (31, 33, 35) and three water level sensors (41, 43, 45), but the storage tank according to the present invention ( 10 may be used in different embodiments according to the purpose and situation to be used.

For example, in the present embodiment, if the second partition 13 is removed and the second storage space 25 and the third storage space 28 are merged to use only two storage spaces, the space for maintaining the water level is reduced. Since the water level is widened with the fluctuating space from time to time, it will be good to use when water is frequently used by the user.

In addition, in this embodiment, even if only the second sterilization apparatus 33 installed in the second partition 13 is removed, if the outputs of the first sterilization apparatus 31 and the third sterilization apparatus 35 are set to be larger, Since sterilization is carried out in two stages without the sterilization apparatus 33, the sterilization effect can be maintained almost unchanged while reducing the power required for sterilization.

The present invention divides the storage tank 10 into a region where the water level is maintained and a section where the level is variable, and the sterilization apparatus of the section where the level is variable so that the output is variable. In addition to the examples, it may be implemented in various embodiments.
