Since the hot water line sterilization line L9, the storage section sterilization line L8 and the drain container 600 are related to the sterilization water generator 400, they will be described together in the description of the sterilization water generator 400 .

[Filtering unit 200]

First, the filtration unit 200 includes at least one water filter for filtering the raw water. For example, as shown in FIG. 1, the pretreatment filter 210, the membrane filter 220 and the after- . ≪ / RTI > However, the number and type of water filters provided in the filtration unit 200 are not particularly limited.

In particular, the pre-processing filter 210 may be composed of one or more filters, and may include at least one of a sediment filter and a pre-carbon filter as an example. At this time, the pre-processing filter 210 may be configured as a composite filter having two or more functions as shown in FIG. 1, but it is also possible that two filters are provided as separate cartridges.

The sediment filter supplies raw water from the raw water supply line (L1) and adsorbs and removes relatively large particulate suspended solids such as sand and solid substances contained in the raw water. In addition, the free carbon filter is supplied with water that passes through the sediment filter, and through the adsorption method of the activated carbon, the chemical such as volatile organic compounds, carcinogens, synthetic detergents, insecticides and the like contained in water and residual chlorine , HOCl or ClO) components.

The membrane filter 220 may further filter the filtered constants by the pre-processing filter 210. For example, a relatively large foreign matter may be filtered in the pre-processing filter 210 and a relatively small foreign matter may be filtered in the membrane filter 220.

To this end, the membrane filter 220 may be coupled to the preprocessing filter 210 by means of integer lines L2 and L3. In addition, a raw water shutoff valve (NOS) may be provided in the integer line L2 and a feed valve FV1 may be provided in the integer line L3. However, if the inflow of raw water can be blocked, the position of the raw water shutoff valve (NOS) is not particularly limited.

2, when the raw water shutoff valve NOS is opened, raw water of the raw water supply source flows into the pre-treatment filter 210 and is filtered. When the feed valve FV1 is opened, The filtered purified water may enter the membrane filter 220 and be filtered.

The membrane filter 220 may be composed of a reverse osmosis membrane filter, for example, in which a part of the introduced water is filtered and the other is not filtered to be discharged to the outside as living water. These reverse osmosis membrane filters remove fine organic and inorganic substances such as bacteria and heavy metals and other metal ions contained in the water through the membrane with fine pores.

In this case, the membrane filter 220 may be connected to the drinking water line L10 as shown in FIG. The domestic water line L10 may be provided with a domestic water valve DV for allowing the domestic water to be drained to the outside while a predetermined pressure is maintained in the membrane filter 220. [ Also, the water supply line L10 may be connected to the drain line DL1.

As a result, the non-filtered living water in the membrane filter 220 flows into the drain line DL1 through the domestic water valve DV and the domestic water line L10 as shown in FIG. 2 and then drained to the outside .

However, the membrane filter 220 is not limited to the above-described reverse osmosis membrane filter, and may be any membrane filter such as a UF membrane (hollow fiber membrane) filter, a nanotrap filter, or the like, as long as it can further filter the purified water filtered by the pre- Any integer filter is possible.

The post-carbon filter 230 may further filter the filtered filtrate in the membrane filter 220. For example, in the after-carbon filter 230, odor causing substances, bacteria, and the like may be filtered.

To this end, the post-carbon filter 230 is connected to the membrane filter 220 by a quadruple L4 so that the purified water filtered in the membrane filter 220, as shown in FIG. 2, And can be filtered.

On the other hand, when the odor-inducing substance or bacteria accumulated in the post-carbon filter 230 is filtered by the post-carbon filter 230, the odor-inducing substance or bacteria are no longer detected by the post- Bacteria can not be filtered. Further, the bacteria accumulated in the after-carbon filter 230 can be propagated in the after-carbon filter 230.

Accordingly, the purified water discharged from the after-carbon filter 230 flows into and is stored in the storage unit 300 in the state including the odor causing substances and bacteria, and the odor and the bacteria Can occur.

In order to solve such problems, the water treatment apparatus 100 according to an embodiment of the present invention periodically filters the after-carbon filter 230 to remove odor causing substances and bacteria accumulated in the after- And may have a configuration for flushing.

As an example, the post-carbon filter 230 can be flushed with the filtered constants by the pre-processing filter 210 and the membrane filter 220 as shown in FIG.

For this purpose, the after-carbon filter 230 may be connected to the filtration-side channel switching valve V1 by a quadruple L5. Further, the filtration-side channel switching valve V1 may be connected to the drain line DL1 by a drain connection line DLC.

3, when the raw water shutoff valve NOS and the feed valve FV1 are opened and the filtration side flow path switching valve V1 is switched to the drain connection line DLC through a control unit not shown in the drawing, The purified water filtered by the preprocessing filter 210 and the membrane filter 220 may flow into the after-carbon filter 230 to flush the after-filter 230.

3, the integer obtained by flushing the after-carbon filter 230 may be introduced into the drain line DL1 through the drain connection line DLC and then discharged to the outside.

When the after-carbon filter 230 is flushed with the purified water filtered by the pre-treatment filter 210 and the membrane filter 220, the bacteria contained in the after-carbon filter 230 can be discharged to the outside.

Further, since the after-carbon filter 230 is flushed with an integral low concentration of TDS (Total Dissolved Solid) by the membrane filter 220, the after- The TDS concentration of an integer that is filtered by the filtration unit 200 and is stored in the storage unit 300 may be lowered when the TDS concentration of an integer is lowered and thus finite after the flushing of the after-carbon filter 230. Accordingly, an integer having a low TDS concentration can be supplied to the user.

On the other hand, the drain connection line DLC is provided with the check valve CV2 to allow the flow from the drain connection line DLC to the drain line DL1, but from the drain line DL1 to the drain connection line DLC Can be made impossible.

The purified water introduced into the purified water tank 310 may be introduced into the cold water tank 320 through the connection hole of the separation member and stored therein. However, the cold water tank 320 is constructed by a separate tank from the purified water tank 310 and connected to the purified water tank 310 by a connection line (not shown) to receive purified water from the purified water tank 310 .

The cold water tank 320 may include an evaporator (not shown) through which refrigerant flows or a cooling unit (not shown) such as a thermoelectric module (not shown) through which heat is transferred from one side to the other side when power is supplied. Accordingly, the purified water flowing into the cold water tank 320 from the purified water tank 310 can be cooled by the cooling unit to become cold water.

The purified water tank 310 may be connected to an purified water discharge line PL1 provided with a purified water discharge valve WV1. The cold water tank 320 may be connected to a cold water discharge line PL2 provided with a cold water discharge valve WV2.

[ Sterilized water  Generating unit 400]

The sterilizing water generating unit 400 may generate sterilized water filtered through at least a part of filters provided in the filtering unit 200. The sterilizing water generating unit 400 may generate sterilizing water filtered by at least some of the plurality of water filters when the filtering unit 200 includes a plurality of water filters have.

1, when a plurality of water filters included in the filtration unit 200 are the pre-treatment filter 210, the membrane filter 220, and the post-carbon filter 230, the sterilizing water generating unit 400 may generate sterilized water filtered through the pretreatment filter 210, i.e., only a portion of the filter.

The sterilizing water generating section 400 may be installed in the sterilizing water generating line L7 branching from the integer line L2 connected to the rear end of the pretreatment filter 210 and sterilized water generating line L7 may be sterilized A feed valve FV2 for opening and closing the water generation line L7 may be provided.

When the feed valve FV2 is opened while the raw water shutoff valve NOS is opened, as shown in FIGS. 4 and 7, the purified water filtered by the pre-treatment filter 210 is mixed with the positive And flows into the sterilizing water generating line L7 and may flow into the sterilizing water producing unit 400. [

However, unlike the above, the sterilizing water generator 400 may generate sterilized water using the purified water in the pre-treatment filter 210 and the membrane filter 220, 220 and the post-carbon filter 230, as shown in FIG. The number and types of water filters of the filtration unit 200 to which the raw water is filtered before flowing into the sterilization water generating unit 400 are not particularly limited.

In addition, a constant flow valve (CFV) may be provided in the sterilizing water producing line (L7) in order to make the flow rate of the purified water flowing into the sterilizing water generating section (400) constant. At this time, the sterilizing water generator 400 and the constant flow valve CFV may be provided as an integrated module, but the present invention is not limited thereto.

On the other hand, the sterilizing water generating section 400 is an electrolytic sterilizer which electrolyzes water to generate electrolytic water (herein, " sterilized water " means water capable of performing at least one of sterilization and cleaning functions) A sterilizer.

In other words, the sterilizing water generating unit 400 may be configured to electrolyze the incoming water (in the present specification, the term 'electrolysis' includes 'oxidation-reduction reaction') to produce mixed oxidant (MO) Sterilizing water containing substances having a sterilizing function and / or a cleaning function. The sterilizing water generating unit 400 sterilizes or extinguishes microorganisms and bacteria remaining in the water by passing water between the electrodes having different polarities. In general, the sterilization of water by electrolysis involves direct oxidation which directly oxidizes the microorganisms in the anode and various mixed oxidants (MO: Mixed Oxidant) such as residual chlorine, ozone, OH radical, oxygen Radicals and the like oxidize the microorganisms.

However, it is preferable that the electrolytic sterilizer described above is applied in order to supply sterilized water of uniform concentration to the sterilizing water generator 400. However, other sterilization water generators known in the art, such as a sterilizer for generating sterilized water by injecting drugs, It does not.

The sterilized water generated by the sterilization water generator 400 may be supplied to the flow path between the hot water generator 330 and the extraction member 500. Specifically, the sterilized water generated by the sterilization water generator 400 may be supplied to the hot water discharge line PL3 through the hot water line sterilization line L9. Further, the hot water line sterilization line L9 may be provided with a feed valve FV4.

Therefore, when the feed valve FV4 is opened, the sterilizing water can be supplied to the hot water discharge line PL3 to sterilize the hot water discharge line PL3.

Although the hot water line sterilization line L9 is shown as being spaced apart from the hot water discharge valve WV3 in FIGS. 1 to 8, the hot water discharge line PL3 between the hot water storage unit 330 and the extraction member 500 The hot water discharge valve WV3 is installed adjacent to the outlet side of the hot water generating portion 330 so as to sterilize a substantial part of the hot water generating line 330 and the hot water discharging line PL3, Is desirably provided adjacent to the hot water discharge valve (WV3) as much as possible.

In addition, sterilized water supplied to the hot water line sterilization line L9 can be discharged through the hot water discharge channel 530 of the extraction member 500 as shown in FIG.

At this time, the drain container 600 may be used for sterilizing the extraction member 500.

The drain container 600 is configured to receive the sterilizing water supplied from the sterilizing water generator 400 and discharged through the extraction member 500 and may be configured as a separate container to be detached from the extraction member 500 , But is not limited thereto.

For example, the drain container 600 is installed inside the water treatment apparatus 100 and is drawn out to the outside of the water treatment apparatus 100 so as to receive the end portion of the extraction member 500 at the time of sterilizing the extraction member 500 The extraction member 500 may have a structure in which the drainage container 600 is installed in advance in the water treatment apparatus 100 and the extraction member 500 is moved toward the drainage container 600 in sterilizing the extraction member 500 .

The extraction member 500 can be sterilized and sterilized by the disinfecting water contained in the drain container 600 during the sterilization process and can be sterilized by the extraction member 500 Can be sterilized and disinfected. In particular, since the end portion of the extraction member 500 is often exposed to the outside, there is a high possibility of contamination due to external factors. However, when the drain member 600 is used as in the embodiment of the present invention, It is possible to sterilize the end portion of the endoscope.

4, the process of disinfecting the flow path between the hot water generating unit 330 and the extracting member 500 by the sterilized water will be described in detail with reference to FIG. 4, wherein the raw water shutoff valve (NOS) The feed valve FV2 of the production line L7 and the feed valve FV4 of the hot water line sterilization line L9 are opened and the sterilizing water producing section 400 is driven, The sterilized water flows into the hot water discharge line PL3 through the hot water line sterilization line L9 to sterilize the hot water discharge line PL3. The sterilized water flowing into the hot water discharge line PL3 is discharged to the outside of the extraction member 500 through the hot water discharge channel 530 and is accommodated in the drain container 600 to be separated from the hot water discharge channel 530 and the extraction member 500 is sterilized.

5, after the hot water discharge line PL3 and the extraction member 500 located between the hot water generator 330 and the extraction member 500 are sterilized, the hot water discharge line PL3 The purified water is supplied from the filtration unit 200 to the hot water discharge line PL3 and the extraction member 500 connected thereto.

At this time, it is also possible to directly supply purified water from the filtration unit 200 to the hot water discharge line PL3. However, when the hot water generating unit 330 is a hot water tank, hot water stored in the hot water tank is discharged to the hot water discharge line PL3 To perform the rinsing process.

Since the disinfecting process of the hot water discharge line PL3 located between the hot water generator 330 and the extracting member 500 uses the separate hot water line sterilization line L9, Can be performed separately.

Therefore, the sterilization process of the hot water discharge line PL3 and the extraction member 500 connected thereto can be performed by the user's selection, and the sterilization process can be performed faster than sterilization of the storage unit 300, (Not shown) so as to be sterilized every time. This first period may be, for example, one day (24 hours), but is not limited thereto.

Also, the sterilizing water generated by the sterilizing water generator 400 may be used to sterilize the storage unit 300.

For this purpose, the sterilizing water generator 400 may be connected to the storage unit 300 by the sterilization line L8. The storage section sterilization line L8 may be provided with a feed valve FV3 for opening and closing the flow channel. The cold water discharge line PL2 may be provided with a discharge side flow path switching valve V2 for switching the flow path between the flow path on the extraction member 500 side and the drain line DL1.

Referring to FIG. 7, the process of disinfecting the storage unit 300 by sterilizing water will be described in detail. The raw water shutoff valve NOS and the feed valve FV2 of the sterilizing water producing line L7 And the feed valve FV3 of the storage section sterilization line L8 is opened and the sterilization water generation section 400 is driven, the sterilization water generated in the sterilization water generation section 400 is supplied to the storage section sterilization line L8, To the storage unit 300 to sterilize the storage unit 300.

The sterilized water generated in the sterilization water generator 400 may flow into the purified water tank 310 and the cold water tank 320 of the storage unit 300 to sterilize the purified water tank 310 and the cold water tank 320 have.
