Extending downward from the center of the lower space 210b to be connected to the second storage tank 220 to supply the purified water to the second storage tank 220 without being mixed with cold water. A connection passage 214 is provided.

When the water level sensor 211 detects that the water level in the first storage tank 210 is a full water level, the raw water valve 150 is turned off to block the supply of raw water, and the balltop 212 is the water level. When the sensor 211 is broken, the inlet through which water is introduced into the first storage tank 210 is blocked at a level higher than the water level sensor 211.

In the present embodiment, it is assumed that both the water level sensor 211 and the ball top 212 are provided, but only the water level sensor 211 or the ball top 212 is provided to control the water level inside the first storage tank 210. It can also be configured as.

When the water level sensor 211 fails, the purified water The supply of purified water and sterilizing water supplied through the supply line 604 is controlled by one ball tower 212.

The sterilization module 300, for example, by electrolyzing water to react with chlorine ions and hydrogen, oxygen, etc. contained in the raw water to generate sterilization materials such as HOCl, ClO ^- ions, positive electrode (not shown) And a negative electrode (not shown), and the positive electrode and the negative electrode may be configured to be supplied with power by a power supply (not shown in the figure), the electrode may be coated with platinum or iridium.

The sterilizing water supply line 612 is configured such that one end thereof is branched from the wastewater drainage line 611 and the other end thereof is connected to the first storage tank 210, so that the wastewater discharge port of the reverse osmosis membrane filter 130 The wastewater discharged through 133 may be supplied to the sterilization module 300 through the sterilization water supply line 612 to generate sterilization water and supply the generated sterilization water to the first storage tank 210.

Wastewater discharged through the wastewater outlet 133 is concentrated water that is not filtered through the reverse osmosis membrane filter 130, and the concentrated water includes dissolved ionic substances (Cl-; chlorine ions) included in the raw water. It is contained at a higher concentration than purified water, so when the electrolysis when passing through the sterilization module 300 can generate more sterilizing material than electrolysis using raw water or purified water can improve sterilization efficiency In addition, since waste water is used as waste water, waste of waste water can be minimized.

A sterilization water supply valve 310 is installed on the sterilization water supply line 612 to control whether water is supplied to the sterilization module 300, and the sterilization water supply line 612 is combined with the purified water supply line 604. Is connected to the ball top 212 of the first storage tank 210. As such, when the purified water supply line 604 and the sterilizing water supply line 612 are combined to be connected to the ball top 212 of the first storage tank 210, the water level sensor 211 or the sterilizing water supply valve 310 is provided. In case of failure), not only the purified water flows into the first storage tank 210 but also the sterilized water is filled into the first storage tank 210 by a predetermined level or more even when the sterilized water flows into the first storage tank 210. Can be blocked, simplifying configuration.

In this embodiment, the configuration in which the purified water supply line 604 and the sterilized water supply line 612 are combined into one, but the purified water supply line 604 is connected to the ball tower 212 and the sterilized water supply line 612 May be configured to be directly connected to the first storage tank 210 without a mechanical shutoff device such as the ball top 212. In this case, the level control of the sterilizing water filled in the first storage tank 210 is made of the water level sensor 211 only.

The water stored in the first storage tank 210 and the second storage tank 220 is supplied to the user through the water intake unit 400. The intake unit 400 is installed on the first intake line 631 connected to the lower space 210b of the first storage tank 210, the first intake valve 410 for regulating the supply of cold water, and The second intake valve 420 is installed on the second intake line 632 connected to the second storage tank 220 to regulate the supply of hot water.

The drainage part 500 controls the discharge rate of the wastewater discharged from the reverse osmosis membrane filter 130 by the wastewater regulator 540 and then drains the wastewater to the outside through the wastewater drainage line 611 as well as the first storage. After sterilizing and filling the sterilizing water into the tank 210 and the second storage tank 220, the sterilizing water is drained to the outside.

In order to drain the sterilizing water in the first storage tank 210 to the outside, the first draining line 641 branched from the first intake line 631 and the second sterilizing water in the second storage tank 220 to the outside. A second drain line 642 is provided for drainage, and two drain valves 510 and 520 are provided for controlling sterilizing water drained through the first drain line 641 and the second drain line 642. .

Since the sterilization mode according to the first embodiment of the present invention is performed in the order of drainage → sterilization water inflow → sterilization water drain → rinsing water inflow → rinsing water drain → water purification inflow, the first embodiment will now be described with reference to FIGS. 2 to 7. The sterilization effect of the water treatment apparatus according to the example will be described.

2 is a view showing an operating state when draining in the water treatment apparatus according to the first embodiment of the present invention, Figure 3 is a view showing a sterilizing water inflow process in the water treatment apparatus according to the first embodiment of the present invention, Figure 4 5 is a view illustrating a sterilization water draining process in a water treatment apparatus according to a first embodiment of the present invention, FIG. 5 is a view showing an operating state when rinsing in a water treatment apparatus according to the first embodiment of the present invention, and FIG. 6 is a first view of the present invention. 7 is a view illustrating an operating state when rinsing water is drained in the water treatment apparatus according to the embodiment, and FIG. 7 is a view showing an operating state of water purification in the water treatment apparatus according to the first embodiment of the present invention.

When the sterilization mode is activated, first, as shown in FIG. 2, the raw water valve 150, the sterilization module 300, and the sterilization water supply valve 310 are in an off state, and the first drain valve 510 and the second drain are discharged. The drain valve 520 drains all of the water in the first storage tank 210 and the second storage tank 220 by operating the drain pump 530 in the on state, and when the drainage is completed, the first drain valve 510, the second drain valve 520, and the drain pump 530 are all in an off state.

Here, Off means a state in which the valves 150, 310, 510, 520 are closed or the state in which the sterilization module 300 and the drain pump 530 are not operated. On means the state in which the valves 150, 310, 510, 520 are open or the sterilization module. Means the state in which the 300 and the drain pump 530 is operated, the same meaning also in the case of other embodiments described later.

In this case, whether the water of the first storage tank 210 and the second storage tank 220 is drained, the load variation detection unit detects a change in voltage / current and receives the detected signal to switch to the next step. It can be configured as.

When the drainage is completed as described above, the sterilizing water inflow process is performed. As shown in FIG. 3, the first drain valve 510, the second drain valve 520, and the drain pump 530 are in an off state, raw water. When the valve 150, the sterilizing water supply valve 310, and the sterilizing module 300 are turned on, the purified water filtered by the reverse osmosis membrane filter 130 passes through the first carbon tank 140 through the post carbon filter 140. Some of the wastewater introduced into the 210 and not filtered by the reverse osmosis membrane filter 130 is discharged to the outside through the wastewater regulator 540 and the wastewater drainage line 611, and the rest is sterilized water supply line 612. Supplied to the sterilization module 300 through, the electrolysis of the waste water passing through the sterilization module 300, such as hypochlorous acid (HClO), hypochlorous acid (OCl-), chlorine (Cl ₂ ) Is generated and flows into the first storage tank 210 and the second storage tank 220.

The amount of wastewater drained through the wastewater drainage line 611 is controlled by the wastewater regulator 540 and then only a very small amount is drained, and most of the remaining wastewater is supplied to the sterilization module 300 through the sterilization water supply line 612. When the electrolyzed wastewater supplied to the sterilization module 300 is promoted the generation of sterilization material to improve the sterilization effect, it is possible to recycle the wastewater discarded, thereby reducing the material source.

That is, since the chlorine component is removed from the pre-carbon filter 120 and the post carbon filter 140, and the chlorine ion (Cl ⁻ ), which is an ionic substance, is removed from the reverse osmosis membrane filter 130, through the filter unit 100. In the case of generating sterilized water in the sterilization module 300 using the filtered purified water, since the concentration of the sterilizing material may be low, in the present invention, the sterilizing water is used by using the waste water which is the concentrated water having a higher concentration of the ionic material than the raw water. To produce.

In this case, the first storage tank 210 and the second storage tank 220 is supplied with purified water through the purified water supply line 604 as well as sterilized water, wastewater supplied to the sterilization module 300 is compared to the raw water Since the sterilized water is generated in a concentration of about 1.2 to 1.5 times higher than that of the sterilized water generated by using the raw water because the concentrated water contains a large amount of ionic substances, the purified water supplied through the purified water supply line 604 is mixed. Even if the sterilizing material concentration of the sterilizing water supplied through the sterilizing water supply line 612 is high, the sterilizing function can be sufficiently performed.

In addition, in the prior art, it was difficult to sterilize the inside of the first intake line 631, but in the present invention, since the sterilization water is filled in the first intake line 631 at the front end where the first intake valve 410 is installed, sterilization is performed. It is possible to minimize the generation zone of the dead zone that is not sterilized in the water treatment apparatus.

The sterilizing water introduced into the first storage tank 210 is also filled in the second storage tank 220 through the connection line 621, and the water level of the first storage tank 210 and the second storage tank 220. When the water level sensor 211 detects that the water level is full, the raw water valve 150, the sterilization module 300, and the sterilization water supply valve 310 are turned off and are sterilized by sterilizing water for a predetermined time. Work is done.

After sterilization is performed by the above process, the sterilization water in the first storage tank 210 and the second storage tank 220 is drained, as shown in FIG. 4, the raw water valve 150 and the sterilization module. 300 and the sterilizing water supply valve 310 maintains an off state and operates the drain pump 530 in a state in which the first drain valve 510 and the second drain valve 520 are turned on. Operated to drain the sterilized water in the first storage tank 210 and the second storage tank 220 to the outside through the waste water drainage line 611 through the first drain line 641 and the second drain line 642. Let's do it.
