The filtered water may be introduced into the sterilizing water generation line LS while passing through the filter 210 and the precarbon filter 220.

In addition, when the water is filtered as shown in FIG. 1 and when the storage tank 300 as shown in FIG. 2 is drained, the water in the sterilizing water generation line LS is operated by operating the flow path switching valve VM. This can be prevented from inflow.

The other side of the sterilization water production line LS may be connected to the storage tank 300 as shown in FIGS. 1 and 5 and 6.

1 and 5 and 6, the sterilization water generation unit 400 provided in the sterilization water generation line LS may be configured to generate sterilization water by electrolyzing the introduced water. For example, the sterilization water generation unit 400 may be configured to generate sterilization water by electrolyzing water introduced by two or more electrodes. Accordingly, the sterilizing water can be generated without adding the sterilizing agent. However, the structure of the sterilizing water generating unit 400 is not limited to this, and any structure known in the art can be used as long as the structure is configured to generate sterilizing water.

With this configuration, as shown in FIGS. 3, 5 and 6, the water of the filtration unit 200 is sterilized by generating a sterilizing water generation line by operating a flow path switching valve VM connected to one side of the sterilizing water generating line LS. It can be flowed into (LS). Then, the water flowing in the sterilized water generation line LS is introduced into the sterilized water generating unit 400 to be sterilized water, and then flows into the storage tank 300 as shown in FIGS. 3 and 5 and 6. As a result, the storage tank can be sterilized. In addition, as shown in FIG. 6, a part of the sterilizing water generated by the sterilizing water generating unit 400 may flow into the filtration unit 200 to sterilize one or more water filters included in the filtration unit 200.

In addition, when the storage tank 300 is not sterilized as shown in FIGS. 1 and 2, the flow path switching valve VM connected to one side of the sterilization water generation line LS is operated to operate the filter 200. Water may be prevented from entering the sterilization water production line (LS).

For example, in a state in which bacteria are propagated inside the purified water filter because the filtration of the water is stopped for a predetermined period of time, bacteria are included in the water passing through the purified water filter at the beginning of the filtration, and the bacteria flow into the storage tank 300 together with the water. You can prevent it.

Therefore, the storage tank 300 is sterilized by the above-described sterilizing water, and as described above, it is possible to prevent bacteria present in the purified water filter from being introduced together with the water, so that it can always be kept clean. . As a result, hygiene of the storage tank 300 may be improved.

The filter sterilization unit 500 may be configured to sterilize the carbon filter included in the filtration unit 200 by sterilization water. Since the carbon filter is more likely to exist and propagate bacteria than other water purification filters, if the carbon filter is sterilized by sterilizing water, a large amount of bacteria that can flow into the storage tank 300 together with water may be sterilized. Can be.

The carbon filter sterilized by the sterilizing water may be a post carbon filter 240. Since the post carbon filter 240 is located closest to the storage tank 300, it is highly likely to send bacteria to the storage tank 300 together with water. Therefore, when the post carbon filter 240 is sterilized by sterilizing water, a large amount of bacteria that can flow into the storage tank 300 together with water may be sterilized.

However, the carbon filter sterilized by the sterilizing water is not limited to the post carbon filter 240 but may also be a precarbon filter 220. The carbon filter is not limited to the carbon filter and is a water filter that is not damaged by the inflow of sterilizing water. Any water filter can be used.

Accordingly, as shown in FIGS. 3 and 5, the sterilizing water introduced into at least one purified water filter included in the filtration unit 200 to sterilize the purified water filter may be drained to the outside through the sterilizing water drain line 530. .

As shown in FIGS. 1 and 5, the sterilizing water drain line 530 may be connected to the filtration line LF by a flow path switching valve VM. Thus, as shown in Figures 3 and 5, the sterilized water sterilized at least one water filter included in the filtration unit 200 by the operation of the flow path switching valve (VM) through the sterilization water drain line 530 Can be drained to. In addition, as shown in FIG. 4, the rinsing water rinsing one or more water filters included in the filtration unit 200 may be drained to the outside through the sterilizing water drain line 530.

The sterilizing water drain line 530 may be connected to the filtration line LF connected to the water inlet of the post carbon filter 240 as shown in FIGS. 1 and 5. Therefore, as shown in FIGS. 3 and 5, the sterilized water that has flowed into the post carbon filter 240 through the outlet of the post carbon filter 240 and sterilizes the post carbon filter 240 is an inlet of the post carbon filter 240. It is discharged through it can be drained to the outside through the sterile water drain line (530). Therefore, the post carbon filter 240 can be sterilized by sterilizing water.

Therefore, the bacteria present in the purified water filter can be prevented from entering the storage tank 300 together with the water.

The sterilizing filter 540 may be a filter having pores of 0.01 μm to 0.1 μm. If the size of the pores formed in the filter is less than 0.01㎛, since the pressure drop is large so that water does not pass easily through the filter, filtration of bacteria through the sterilization filter 540 may not be easy. For example, water may pass through the sterilization filter 540 to use a high pressure pump to filter bacteria. In addition, when the size of the pores formed in the filter exceeds 0.1㎛, because some of the bacteria can pass through the pores, it may be difficult to filter the bacteria through the sterilization filter 540.
