Description

Water treatment equipment {WATER TREATMENT APPARATUS}

The present invention relates to a water treatment device that filters water and supplies it to a user, and more specifically, to a direct water treatment device in which water is discharged by the pressure of raw water.

A water treatment device is a device that treats incoming water and discharges it to the outside to supply drinking water to users.

Such water treatment devices include water purifiers that include one or more water purification filters to filter incoming water and then supply it to users. In addition to these water purifiers, carbonated water machines that supply carbon dioxide to inflowing water and then supply it to users, and ionized water machines that electrolyze inflowed water to change it into alkaline water and acidic water and supply it to users are also water treatment devices.

This water treatment device includes a tank-type water treatment device (water purifier) that stores filtered purified water in a storage tank and supplies the water contained in the storage tank to the user using the height difference between the storage tank and the extraction member, and It can be classified into a direct water treatment device (water purifier) where water is discharged.

Conventional tank-type water treatment devices had the problem that purified water stored in a storage tank for a long period of time was contaminated by bacteria, etc., thereby reducing sanitation. In order to solve this problem, a method of sterilizing and disinfecting the storage tank by supplying sterilizing water to the storage tank has been proposed.

However, the conventional tank-type water treatment device had the problem of not being able to sterilize the flow path at the rear of the storage tank because the sterilizing water used to sterilize the storage tank was discharged directly into the drain passage connected to the bottom of the storage tank.

In particular, since conventional sterilization methods relate to tank-type water treatment devices, a sterilization method suitable for direct-flow water treatment devices is required.

The filtration unit 200 includes at least one water purification filter to filter raw water, for example, as shown in FIG. 1, includes a pre-treatment filter 210, a membrane filter 220, and a post-carbon filter 230. can do. However, the number or type of water purification filters provided in the filtration unit 200 is not particularly limited.

Specifically, the pre-treatment filter 210 may be composed of one or more filters, and as an example, may include at least one of a sediment filter and a free carbon filter. At this time, the pre-treatment filter 210 may be configured as a complex filter with two or more functions as shown in FIG. 1, but it is also possible for the two filters to be provided as separate cartridges.

The sediment filter receives raw water from the raw water supply line (L1) and has the function of adsorbing and removing solid substances such as relatively large suspended solids and sand contained in the raw water. In addition, the free carbon filter receives water that has passed through the sediment filter and uses activated carbon adsorption to remove chemicals harmful to the human body such as volatile organic compounds, carcinogens, synthetic detergents, and pesticides contained in the water, as well as residual chlorine (e.g. , HOCl or ClO) components.

The membrane filter 220 can additionally filter the purified water filtered by the pre-treatment filter 210. For example, relatively large foreign substances may be filtered in the pre-treatment filter 210 and relatively small foreign substances may be filtered in the membrane filter 220.

To this end, the membrane filter 220 may be connected to the pre-treatment filter 210 through water purification lines (L2, L3). Additionally, a raw water shut-off valve (NOS) may be provided in the purified water line (L2), and a feed valve (FV1) may be provided in the purified water line (L3). However, the location of the raw water shutoff valve (NOS) is not particularly limited as long as it can block the inflow of raw water.

Accordingly, as shown in FIG. 2, when the raw water shutoff valve (NOS) is opened, raw water from the raw water supply source flows into the pre-treatment filter 210 and is filtered, and when the feed valve (FV1) is opened, the raw water from the raw water supply source flows into the pre-treatment filter 210. The filtered purified water may flow into the membrane filter 220 and be filtered.

The membrane filter 220 may be a UF membrane (hollow fiber membrane) filter, nanotrap filter, etc. to secure a sufficient flow rate of purified water extracted from the extraction member 500. However, the reverse osmosis membrane filter is not suitable for the direct water treatment device 100 according to the present invention in that the discharge water flow rate is small, but the use of the reverse osmosis membrane filter as the membrane filter 220 of the present invention is excluded. no.

The post-carbon filter 230 can additionally filter the purified water filtered by the membrane filter 220. For example, odor-causing substances or bacteria may be filtered through the post-carbon filter 230.

To this end, the post-carbon filter 230 is connected to the membrane filter 220 by a water purification line (L4), so that the purified water filtered in the membrane filter 220 is supplied to the post-carbon filter 230, as shown in FIG. 2. may be introduced and filtered.

In this way, the purified water filtered in the filtration unit 200 can be provided to the user through the direct water discharge line unit 300 and the extraction member 500, which will be described later.

[Direct water discharge line unit (300)]

The direct water discharge line unit 300 is located between the filter unit 200 and the extraction member 500 in order to provide the user with purified water filtered by the filter unit 200, and is connected to the filter unit by the purified water connection line (L6). Connected to (200).

For example, as shown in FIG. 2, the purified water connection line (L6) may be connected to the feed valve (V1) connected to the post-carbon filter 230 of the filtration unit 200 through the purified water line (L5). And, when the feed valve V1 is opened, purified water filtered in the filter unit 200 may flow into the direct discharge line unit 300.

This direct discharge line unit 300 includes a purified water discharge line (PL1) for extracting room temperature purified water filtered in the filtration unit 200 by the pressure of raw water, and a purified water discharge line (PL1) for extracting cooled purified water by the pressure of raw water. At least one discharge line may be provided among a cold water discharge line (PL2) and a hot water discharge line (PL3) for extracting heated purified water using the pressure of raw water. In Figure 1, the direct water discharge line unit 300 is shown to include all purified water discharge line (PL1), cold water discharge line (PL2), and hot water discharge line (PL3), but the function of the water treatment device 100 is not implemented. For this reason, it is possible that some of these discharge lines are not used. For example, as shown in FIG. 5, the hot water discharge line PL3 may not be provided. However, for convenience of explanation, hereinafter, an example in which a purified water discharge line (PL1), a cold water discharge line (PL2), and a hot water discharge line (PL3) are all provided, as shown in FIG. 1, will be described.

The purified water discharge line PL1 is provided to provide the user with room temperature purified water filtered by the filtration unit 200. For this purpose, the purified water discharge line PL1 may be provided with a purified water discharge valve WV1. Therefore, when the user selects extraction of room temperature purified water, the raw water shutoff valve (NOS), feed valve (FV1), feed valve (V1), and purified water discharge valve (WV1) are opened, and accordingly, as shown in FIG. 2 The purified water filtered in the filtration unit 200 may flow into the purified water discharge line (PL1) through the purified water connection line (L6), connection port (C2), and connection port (C3) and then be discharged to the extraction member (500). .

In addition, the cold water discharge line PL2 is provided to cool the purified water filtered in the filter 200 and provide it to the user. This cold water discharge line (PL2) may be provided with a cold water discharge valve (WV2), and may be provided with a cold water generator 340 for cooling the room temperature purified water filtered by the filter unit 200.

This cold water generator 340 has a tank structure that accommodates cold water inside, and when raw water flows in, a direct-water cold water tank in which the cooled cold water is pushed by the raw water pressure and discharged to the outside may be used. This direct-water cold water tank is configured to be directly connected to the filtration unit 200 to enable extraction of cold water by the pressure of raw water.

This cold water generator 340 may be equipped with a cooling unit (not shown) such as an evaporator (not shown) through which refrigerant flows or a thermoelectric module (not shown) that transfers heat from one side to the other when power is applied. there is.

Alternatively, the cold water generator 340 may not be provided with an ice storage type cold water generating means that cools by the ice storage method. This ice storage type cold water generating means is provided with an ice storage tank configured to partially form ice in the water contained therein, and the cold water discharge line (PL3) is configured to pass through the ice storage tank, so that the water flowing through the cold water discharge line (PL3) is frozen. It may be configured to form cold water by exchanging heat with the ice storage water contained in the structure.

However, the configuration of the cold water generator 340 is not limited to the above-mentioned direct water type cold water tank or ice shaft type cold water generation means, and other known configurations may be adopted as long as cold water can be extracted by the pressure of raw water. .

Then, when the user selects extraction of cooled purified water (cold water), the raw water shutoff valve (NOS), feed valve (FV1), feed valve (V1), and cold water discharge valve (WV2) are opened, and accordingly, as shown in FIG. 2 As described above, the purified water filtered in the filtration unit 200 flows into the cold water discharge line (PL2) through the purified water connection line (L6), connection port (C2), and connection port (C3) and then into the cold water generator 340. It may be cooled and discharged to the extraction member 500.

In addition, the hot water discharge line PL3 is provided to heat the purified water filtered in the filtration unit 200 and provide it to the user. This hot water discharge line (PL3) may be provided with a hot water discharge valve (WV2) and a hot water generator 350 for heating the room temperature purified water filtered by the filtering unit 200.

This hot water generator 350 may use an instantaneous heating device configured to instantaneously heat and discharge purified water flowing through an internal flow path by a heating unit.

Therefore, when the user selects extraction of heated purified water (hot water), the raw water shutoff valve (NOS), feed valve (FV1), feed valve (V1), and hot water discharge valve (WV3) are opened, and accordingly, as shown in FIG. 2 As shown, the purified water filtered in the filtration unit 200 flows into the hot water discharge line (PL3) through the purified water connection line (L6) and the connection port (C2), and is then heated by the hot water generator 350 to produce an extraction member ( 500).

Meanwhile, as shown in FIG. 1, the purified water discharge line (PL1) and the cold water discharge line (PL2) are joined to form a discharge connection line (PLW), and the discharge connection line (PLW) is connected to the extraction member 500. It can be configured as follows.

In this case, as shown in FIG. 2, room temperature purified water discharged from the purified water discharge line (PL1) may be discharged from the extraction member 500 through the discharge connection line (PLW), and may be discharged from the cold water discharge line (PL2). The cooled purified water discharged may be discharged from the extraction member 500 through a discharge connection line (PLW).

However, differently from this, the purified water discharge line PL1 and the cold water discharge line PL2 may be configured to be connected to the extraction member 500 instead of joining.

In addition, in Figure 1, the purified water discharge line (PL1) and the cold water discharge line (PL2) are branched from the connection port (C3), and the hot water discharge line (PL3) is shown to be branched from the connection port (C3). The order or branching structure of the discharge lines can be changed in various ways.

[ sterilizing water Generation unit (400)]

The sterilizing water generating unit 400 may generate sterilizing water using purified water filtered through at least some filters provided in the filtration unit 200. As described above, when the filtration unit 200 includes a plurality of water purification filters, the sterilizing water generator 400 can generate sterilizing water using purified water filtered by at least some of the plurality of water purification filters. there is.

For example, as shown in FIG. 1, when the plurality of water purification filters included in the filtration unit 200 are a pre-treatment filter 210, a membrane filter 220, and a post-carbon filter 230, the sterilizing water generating unit ( 400) can generate sterilizing water using purified water filtered through the pre-treatment filter 210, that is, only a portion of the filter.

To this end, the sterilizing water generator 400 can be installed in the sterilizing water generation line (L7) branched from the purification line (L2) connected to the rear end of the pre-treatment filter 210 through the connection port (C1), and the sterilizing water The production line (L7) may be provided with a feed valve (FV2) for opening and closing the sterilizing water production line (L7).

And, when the feed valve (FV2) is opened while the raw water shutoff valve (NOS) is open, the purified water filtered from the pre-treatment filter 210 flows into the purified water line (L2), as shown in FIGS. 3 and 4. The sterilizing water may flow through the sterilizing water generation line (L7) and flow into the sterilizing water generating unit 400.

However, unlike the above, the sterilizing water generator 400 may generate sterilizing water using purified water filtered by the pre-treatment filter 210 and the membrane filter 220, and the pre-treatment filter 210 and the membrane filter ( Sterilizing water can also be produced from purified water filtered through the 220) and post-carbon filter 230. As such, the number or type of water filters in the filtration unit 200 through which raw water is filtered before flowing into the sterilizing water generating unit 400 is not particularly limited.

Additionally, the sterilizing water production line L7 may be equipped with a constant flow valve (CFV) to maintain a constant flow rate of purified water flowing into the sterilizing water generator 400. At this time, the sterilizing water generator 400 and the constant flow valve (CFV) may be provided as an integrated module, but are not limited thereto.

Meanwhile, the sterilizing water generator 400 is an electrolytic sterilizer that generates sterilizing water (in this specification, 'sterilizing water' refers to water that can perform at least one of sterilizing and cleaning functions) by electrolyzing water. It can be done with

That is, the sterilizing water generator 400 electrolyzes the introduced water (in this specification, the term electrolysis is described as including 'redox reaction') to produce an oxidizing mixture (MO: Mixed Oxidant). It may be configured to produce sterilizing water containing a substance with a sterilizing function and/or a cleaning function. This sterilizing water generator 400 sterilizes or destroys microorganisms or bacteria remaining in the water by passing water between electrodes of different polarities. In general, sterilization of purified water through electrolysis involves a direct oxidation reaction that directly oxidizes microorganisms at the anode, and various oxidizing substances (MO:Mixed Oxidants) that can occur at the anode, such as residual chlorine, ozone, OH radical, and oxygen. It is achieved through a complex process of indirect oxidation reactions in which radicals, etc. oxidize microorganisms.

However, the sterilizing water generator 400 preferably uses the electrolytic sterilizer described above in order to supply sterilizing water at a uniform concentration, but excludes other known sterilizing water generators such as chemical sterilizers that generate sterilizing water by adding chemicals. It's not like that.

In addition, the sterilizing water generated in the sterilizing water generating unit 400 may be supplied to the direct water discharge line unit 300 through the discharge line sterilization line L8 connected to the direct water discharge line unit 300. The sterilizing water production line (L7) can be branched into the discharge line sterilization line (L8) and the sterilizing water supply line (SL) described later. For this purpose, the discharge line sterilization line (L8) and the sterilizing water supply line (SL) ) A flow path switching valve (FV3) may be provided at the branch point.

In a state where the passage of the flow path switching valve (FV3) is switched to the discharge line sterilization line (L8), the sterilizing water generated in the sterilizing water generator 400 is discharged directly through the discharge line sterilization line (L8). It can be supplied to each discharge line (PL1, PL2, and PL3) provided in the line unit 300.

Looking in detail at the sterilization and disinfection operation of the direct water discharge line unit 300 with reference to FIG. 3, the raw water shutoff valve (NOS) and the feed valve (FV2) of the sterilizing water production line (L7) are operated by a control unit (not shown). is opened, the flow path of the flow path switching valve (FV3) is switched to the discharge line sterilization line (L8) side, and the sterilizing water generator 400 is driven. Accordingly, the sterilizing water flowing into the direct discharge line unit 300 through the discharge line sterilization line (L8) is discharged into the purified water discharge line (PL1) and the discharge connection line (PLW) according to the opening of the purified water discharge valve (WV1). It can be discharged to the extraction member 500 through the cold water discharge valve (WV2), and upon opening of the cold water discharge valve (WV2), it can be discharged to the extraction member 500 through the cold water discharge line (PL2) and discharge connection line (PLW). As the discharge valve (WV3) is opened, hot water may be discharged to the extraction member (500) through the hot water discharge line (PL3). In this way, the sterilizing water supplied to the direct discharge line unit 300 is discharged through the extraction member 500, making it possible to sterilize each discharge line and the extraction member 500.

At this time, sterilization of each discharge line may be performed simultaneously or sequentially. Alternatively, it is also possible to perform sterilization of only some discharge lines and not perform sterilization of the remaining discharge lines.

In addition, the water treatment device 100 according to the first embodiment of the present invention includes a connection pipe member selectively connected to the extraction member 500 to supply sterilizing water discharged through the extraction member 500 to the drain line DL1. (CL) may be additionally included. That is, the connection pipe member CL is connected to the extraction member 500 during sterilization and disinfection work, and may be separated from the extraction member 500 in other cases.

This connector member (CL) may be configured to be inserted into the extraction member 500 by the user when performing sterilization and disinfection work, but is not limited to this.

In addition, a drain pump 700 is provided in the drain line (L1) to ensure smooth drainage through the drain line (DL1). In addition, the drain line (L1) is equipped with a backflow prevention valve (CV1) to prevent backflow from occurring when water is drained through the drain line (DL1).

Meanwhile, although not shown in FIG. 3, after sterilization and disinfection work is performed by supplying sterilization water to the discharge line of the direct discharge line unit 300, a rinsing operation is performed to remove the sterilization water remaining in the sterilized discharge line. This can be done. As shown in FIG. 3 , this rinsing operation can be performed by supplying purified water to the extraction member 500 as shown in FIG. 2 while the connection pipe member CL is connected to the extraction member 500 .

Sterilization of the direct water discharge line unit 300 with sterilizing water may be performed once in a preset cycle (for example, 5 to 7 days). However, the sterilization cycle of the direct water discharge line unit 300 is not particularly limited.

Meanwhile, as shown in FIGS. 1 and 4, the water treatment device 100 according to the first embodiment of the present invention has a sterilizing water supply line (SL) for extracting sterilizing water generated in the sterilizing water generator 300. ) may additionally be included.

This sterilizing water supply line (SL) can be installed independently from the extraction member 500, but is connected to the extraction member 500 as shown in FIGS. 1 and 4 for sterilization and disinfection of the extraction member 500. It can be configured.

Looking at the sterilization and disinfection operation of the extraction member 500 in detail with reference to FIG. 4, the raw water shutoff valve (NOS) and the feed valve (FV2) of the sterilizing water production line (L7) are opened by a control unit (not shown). The flow path of the flow path switching valve (FV3) is switched to the sterilizing water supply line (SL) side and the sterilizing water generator 400 is driven. Accordingly, the sterilizing water flowing into the sterilizing water supply line (SL) is used to sterilize the extraction member 500, and is discharged to the drain line DL1 through the connection pipe member (CL) connected to the extraction member 500. .

In this way, the sterilization treatment of the extraction member 500 can be performed separately from the sterilization of the direct water discharge line unit 300 because a separate sterilizing water supply line (SL) is used.

Therefore, the sterilization treatment of the extraction member 500 can be performed by the user's selection, and since it can be performed faster than the sterilization of the above-described direct discharge line unit 300, the control unit (not shown) is used to sterilize the extraction member 500 at every short preset cycle. ) can be controlled by. The sterilization cycle of the extraction member 500 may be, for example, 1 day (24 hours), but is not limited thereto.

Meanwhile, although not shown in FIG. 4, after sterilizing and disinfecting the extraction member 500, a rinsing operation may be performed to remove the sterilizing water remaining in the extraction member 500. In this rinsing operation, when the sterilization and disinfection operation of the material 500 is completed, the open and closed states of various valves are maintained, but only the operation of the sterilizing water generating unit 400 is stopped, and the purified water filtered in the filtration unit 200 is transferred to the extraction member 500. ) can be performed by supplying to.

However, unlike this, the rinsing operation may be performed by supplying purified water to the extraction member 500 as shown in the flow path configuration shown in FIG. 2 while the connector member CL is connected to the extraction member 500.

On the other hand, if the user wishes to extract the sterilizing water to use it for another purpose, the connector member (CL) may not be connected to the extraction member 500, and as a result, the sterilizing water discharged through the extraction member 500 may be removed. It is also possible to receive it in another container and use it for an appropriate purpose.

As described above, according to the water treatment device 100 according to the first embodiment according to the present invention, using the sterilizing water generated by the sterilizing water generating unit 400, the water treatment device provided in the direct water discharge line unit 300 Not only can various discharge lines be sterilized, but it is also possible to sterilize only the extraction member 500 separately.

In addition, according to the water treatment device 100 according to the present invention, the extraction member 500 can be sterilized or disinfected according to the user's selection or at a preset short first cycle (for example, every day), and separately, at a preset time. Every second cycle (e.g., 5 to 7 days), various discharge lines provided in the direct water discharge line unit 300 and the cold water generator 340 or hot water generator 350 provided therein are sterilized and disinfected. This can achieve the effect of improving hygiene.
