Description

Electrolyzed water generating device

The present invention relates to an electrolyzed water generating apparatus for producing electrolyzed water of electrolytic regenerated water and electrolytic acidic water by electrolyzing raw water such as tap water.

In an electrolyzed water generating device (generally referred to as a "water purifier") that processes raw water such as tap water to generate electrolyzed water, generally, raw water is introduced into an electrolytic cell for electrolysis to generate electrolytic regenerated water (generally referred to as "alkaline ion". Water") and electrolyzed water of electrolytic acid water (generally referred to as "acidic ion water") are more common. The produced electrolyzed water, especially electrolyzed regenerated water, has antioxidant properties, and the effect of improving gastrointestinal symptoms after drinking is well known. In addition, the effect of electrolyzed acidic water on sterilization is well known.

The electrolyzed water generating apparatus generally includes an apparatus main body provided with the above electrolytic cell, various piping systems, and the like, and an inlet pipe and a pair of drain pipes which are taken out from the main body of the apparatus. The electrolyzed water generating device introduces raw water into the electrolytic cell through a pipeline system connected to the inlet pipe, electrolyzes the raw water in the electrolytic cell, and then electrolyzes the regenerated water by a pipeline system connected to the pair of drain pipes respectively. The electrolytic acid water is distilled out from the electrolytic cell and discharged.

For example, Japanese Laid-Open Patent Publication No. Hei. 6-47381 (Patent Document 1), Japanese Patent Laid-Open Publication No. 2002-86148 (Patent Document 2), and Japanese Patent Publication No. No. 2010-221127 (Patent Document 3) and the like.

In the above-described electrolyzed water generating apparatus, cations such as calcium and magnesium contained in the raw water may cause precipitation of scales such as calcium hydroxide and magnesium hydroxide. The portion where the scale is deposited is, for example, a cathode chamber of the electrolytic cell, a piping system and a drain pipe located downstream of the cathode chamber, and the like. In particular, in order to promote electrolysis, an electrolyzed water generating device of an electrolytic accelerator type such as calcium lactate or salt is added to raw water before entering the electrolytic cell, and the precipitation of the scale is remarkable.

This scale is caused not only by the cathode and the electrolytic separator attached to the electrolytic electrode, but also because the performance of the electrolyzed water generating apparatus is lowered, and the pipe wall and the valve member adhering to the piping system cause clogging and cause malfunction. Therefore, in the past, in order to remove scale, the industry actively proposed various methods.

The method for removing scale is roughly classified into two types. One is a method of using the generated electrolytic acidic water in the electrolytic cell to perform scale removal, and the other is a method of introducing a cleaning liquid represented by citric acid water or the like from the outside to perform scale removal.

The former scale removal method is generally referred to as reverse current cleaning, and is a method of removing scale by inverting the polarity of a pair of electrolytic electrodes. This method is also employed in the electrolyzed water generating apparatus disclosed in Japanese Laid-Open Patent Publication No. Hei. 6-47381, Japanese Patent Application Publication No. 2002-86148, and Japanese Patent Publication No. 2010-221127.

Specifically, an electrolyzed water generating apparatus disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. With the pipeline located on the upstream side of the electrolytic cell, when performing reverse current cleaning, The electrolytic acid water is fed back by using a bypass pipe to clean not only the electrolytic cell but also most of the piping system and the drain pipe.

Further, an electrolyzed water generating apparatus disclosed in Japanese Laid-Open Patent Publication No. 2010-221127 is provided with a flow path switching valve on the downstream side of the electrolytic cell so that one of the electrolytic cells and one of the downstream sides of the electrolytic cell are disposed The connection state between the drain pipes can be switched. When the reverse current cleaning is performed, the connection state is switched by the flow path switching valve, and not only the electrolytic cell but also most of the piping system and the drain pipe are cleaned.

On the other hand, in the latter method of removing scale, a cleaning liquid such as citric acid water having a concentration adjustable can be introduced from the outside, and the cleaning liquid can also flow through the entire electrolytic cell, the pipeline system, and a pair of drain pipes.

The latter method for removing scale is generally carried out in a pipeline on the upstream side of the electrolytic cell, and a cleaning filter element containing a cleaning component is installed, and the drain port of the drain pipe located on the downstream side of the anode chamber is blocked, and the raw water is introduced from the outside by the inlet pipe. Filling the electrolysis tank, the pipeline system and the pair of drain pipes with the cleaning liquid, and after leaving it for a certain period of time, opening the discharge port of the drain pipe on the downstream side of the anode chamber, so that the raw water flows at another specific time, and then, The cleaning filter element is taken out, and the raw water is further passed through to discharge the cleaning liquid remaining in the electrolytic cell, the line system, and the pair of drain pipes.

However, when the scale removing method of the former is used, although the scale adhering to the surface of the electrolytic electrode can be effectively removed, the scale adhering to other portions of the electrolytic chamber, and the piping system and the drain pipe attached to the downstream side of the electrolytic cell If the scale is removed, there is an insufficient situation. That is to say, the electrolytic acid water does not have the ability to completely remove and remove the scale, so that the electrolysis chamber, the pipeline system and the drain pipe other than the electrolysis electrode gradually accumulate, which leads to consideration of the actual use frequency. The reverse current cleaning does not achieve the desired effect of completely removing scale.

Further, in the electrolyzed water generating apparatus, in order to prevent mis-drinking and misuse of the electrolyzed water, it is generally preferred to configure the electrolyzed reclaimed water to be discharged from one side of the drain pipe and to discharge the electrolyzed acid water from the drain pipe on the other side. Therefore, the electrolyzed water generating apparatus disclosed in Japanese Laid-Open Patent Publication No. Hei No. 6-47381, and the Japanese Patent Laid-Open Publication No. 2002-86148, which has the above-mentioned structure, can prevent electrolyzed water even in the case of reverse current cleaning. The advantages of accidental drinking and misuse; however, relatively, the scale in the drain pipe which generally discharges the electrolyzed reclaimed water cannot be removed.

In contrast, in the electrolyzed water generating apparatus disclosed in Japanese Laid-Open Patent Publication No. 2010-221127, when the reverse current cleaning is performed, the connection state between the electrolysis chamber and the drain pipe can be switched, and the electrolytic acid water can be circulated. On both sides of the pair of drain pipes; however, in contrast, when the electrolytic cleaning is performed, since the above conditions cannot be formed, the user cannot be prevented from drinking by mistake. Problems such as electrolysis of water or misuse occur.

On the other hand, the latter method for removing scale includes the advantage of completely removing scale, and the fact that a cleaning operation is performed more than usual from the beginning, thereby preventing the user from operating the mistake and accidentally drinking or misusing the electrolyzed water. In terms of advantages, it is better than the former method of scale removal.

However, when the above-described latter scale removing method is employed, it is necessary to separately prepare a filter element for special cleaning, and since it is necessary to install the apparatus for mounting the cleaning filter element in the apparatus for the body of the electrolyzed water generating apparatus, the economical aspect The issue needs to be evaluated again. In addition, since the operation at the time of cleaning is cumbersome, there may be problems such as a user's operation error. In particular, when the state in which the cleaning liquid is filled in the electrolytic cell, the line system, and the drain pipe cannot be sufficiently maintained, there is a problem that scale cannot be sufficiently removed.

As described above, the conventional scale removing method is highly demanded because of the problem that the scale cannot be sufficiently removed, is uneconomical, and the cleaning operation is cumbersome.

Accordingly, an object of the present invention is to provide an electrolyzed water generating apparatus which can be used to solve the above problems, which can efficiently and easily remove scales in all parts where scale adheres, and is also excellent on an economical surface.

The inlet pipe 11 is connected to a faucet or the like of a tap water pipe, and receives a raw water supply line such as tap water from the outside, and has a supply port 11a for supplying raw water at the tip end. The inlet pipe 11 can be pulled out from the bottom of the casing 10 toward the outside of the casing 10.

The first drain pipe 12 is a line for discharging the generated electrolytic reclaimed water (alkaline ionized water) to the outside, and has a first discharge port 12a at its tip end. The first drain pipe 12 can be pulled out from the top end of the outer casing 10 toward the outside of the outer casing 10.

The second drain pipe 13 can be pulled out from the bottom of the outer casing 10 toward the outside of the outer casing 10.

Further, the electrolyzed water generating apparatus 1A of the present embodiment has a purpose It is supplied to potable electrolyzed regenerated water which is produced when a general electrolytic treatment is performed. Therefore, the first drain pipe 12 that discharges the electrolyzed water is formed by a nozzle that can be arbitrarily changed in direction and position, and the second drain pipe 13 that discharges the electrolytic acid water is formed by a drain hose.

An operation unit 14 for operating the electrolyzed water generating apparatus 1A is installed above the outer casing 10. The operation unit 14 can be configured, for example, by a button or the like, and includes a power button, an operation state switching button, various setting buttons, and the like. Further, a display unit 15 for displaying an operation state or the like is provided in front of the casing 10. The display unit 15 can be configured by, for example, an LCD (Liquid Crystal Display) or the like.

As shown in FIG. 2 and FIG. 3, various components such as a piping system, an electrolytic cell, and a purification processing unit which will be described later are housed inside the casing 10. These components are assembled on the base 17 of the outer casing 10 placed on a plane of placement adjacent the sink.

As shown in FIG. 2 or FIG. 4, the above constituent members mainly include a safety valve 20, a purification processing unit 21, a check valve 22, a flow rate detector 23, a valve block 25, an electrolytic cell 28, a centrifugal pump 30, and each other.

As shown in FIG. 4, the pipeline system of the lines L1 to L6 determines the flow path provided inside the casing 10, and is connected to the inlet pipe 11, the first drain pipe 12, and the second drain pipe 13. More specifically, the line L1 is connected to the inlet pipe 11 and the purification processing unit 21; the line L2 is connected to the purification processing unit 21, and The electrolytic cells 28 are connected. The line L3 is connected to the electrolytic cell 28 and the first drain pipe 12, and the line L4 is connected to the electrolytic cell 28 and the second drain pipe 13. Further, the line L5 is connected to the line L2 and the line L4, and the line L6 is connected to the inlet pipe 11 and the second drain pipe 13.

When the supply amount of the raw water mainly from the outside is excessively large, the safety valve 20 is for directly discharging the supplied raw water to the outside, and is connected to the inlet pipe 11, the line L1, and the line L6. By providing the above-described safety valve 20, it is possible to prevent an excessive load from being caused to various constituent members to be described later, and to prevent backflow of raw water.

The purification processing unit 21 is for purifying the supplied raw water, and is connected to the line L1 and the line L2. The purification treatment unit 21 includes a purification filter element 21a such as an activated carbon filter, a hollow fiber filter, or a filter of these combinations. By installing the above-described purification treatment unit 21, electrolytically regenerated water suitable for drinking can be produced.

When the check valve 22 is opened in the later-described cleaning operation, a circulation circuit for the cleaning liquid can be formed by opening the valve, which is installed in the line L2 and connected to the line L5. In addition, the check valve 22 can also be used as a pressure relief valve, which is borrowed when water is stopped as described later. This valve is opened to drain the raw water and reclaimed water that are filled in the pipeline system. By installing the check valve 22, not only the circulation circuit of the cleaning liquid can be formed during the cleaning operation, but also the residual water remaining in the line can be reduced when the water is stopped. Further, when the check valve 22 is closed during the general operation of generating the electrolyzed water, the line L2 and the line L5 can be disconnected.

The flow rate detector 23 is for detecting the flow rate of the supplied raw water and is installed on the line L2. The traffic detector 23 is configured to detect whether the supply of raw water is performed, and the detection result is outputted in the control unit 40. The control unit 40 determines whether to start/stop electrolysis, or control one of the flow control valves 27A and 27B, which will be described later, or whether to apply a voltage to one of the electrolysis electrodes 28a and 28b, which will be described later, based on the detection result of the output.

A branch line 24 is installed on the downstream side of the position where the flow rate detector 23 of the line L2 is installed. The branch line 24 has a pair of branch lines 24a, 24b for flowing raw water. By installing the branch line 24, the raw water can be introduced into one of the electrolytic cells 28 to be described later.

The pair of branch lines 24a and 24b are respectively connected to one of the inlet ports of the flow path switching valve 26A, and one of the flow path switching valves 26B is connected to one of the electrolysis cells 28 to the electrolysis chamber. Further, a flow rate control valve 27A is attached to the branch line 24b on one side.

The flow control valve 26A is for switching between the pair of branch lines 24a and 24b and one of the electrolytic cells 28 to the electrolysis chamber (hereinafter, the electrolysis chamber on one side is referred to as a first electrolysis chamber, and the electrolysis chamber on the other side is referred to as a second electrolysis chamber). The connection state between the chambers is controlled by the control unit 40. Specifically, the operation of the flow control valve 26A can be controlled by the control unit 40 in the branch line 243. Simultaneously with the connection to the first electrolysis chamber, the first connection state formed by connecting the branch line 24b and the second electrolysis chamber is switched to be connected to the branch line 24a and the second electrolysis chamber, and the branch line 24b and the second electrolysis chamber are simultaneously connected. The second connection state of the connection.

The flow control valve 27A is used as a throttle valve to adjust the flow rate of the raw water flowing in the branch line 24b to a flow rate lower than that of the raw water flowing in the branch line 24a. This operation is controlled by the control unit 40. . The flow rate control valve 27A can adjust the ratio of the produced electrolyzed water to the electrolytic acid water to adjust the amount of electrolytic regenerated water to be generated more than the electrolytic acid water. Therefore, it is also called a proportional adjustment valve.

The electrolytic cell 28 includes a pair of electrolytic electrodes 28a and 28b and an electrolytic separator 28c for separating the pair of electrolytic electrodes 28a and 28b. By applying a voltage between the electrolytic electrodes 28a and 28b, the raw water is electrolyzed. Here, the pair of electrolytic electrodes 28a and 28b are disposed in one of the electrolysis chambers separated by the electrolytic separator 28c, and the electrolytic chamber disposed on the electrolytic electrode 28a corresponds to the first electrolytic chamber, and the electrolytic electrode 28b is disposed. The electrolysis chamber corresponds to the second electrolysis chamber described above.

The polarity of the electrolytic electrodes 28a and 28b can be switched, and the polarity of the electrolytic electrodes 28a and 28b can be reversed by simultaneously switching the polarities of the electrolytic electrodes 28a and 28b. Further, switching of the polarities of the above-described electrolytic electrodes 28a, 28b can be performed, for example, by a relay not shown in the drawing, and the control unit 40 controls switching.

Thereby, when the electrolysis electrode 28a is an anode and the electrolysis electrode 28b is a cathode, the first electrolysis chamber is an anode chamber, and the second electrolysis chamber is When the electrolysis electrode 28a is a cathode and the electrolysis electrode 28b is an anode, the first electrolysis chamber is a cathode chamber, and the second electrolysis chamber is an anode chamber.

The electrolysis electrode can utilize, for example, an electrode having a surface plated with platinum. The electrolytic separator 28c is used to pass cations such as potassium ions, magnesium ions, sodium ions, calcium ions, etc. from the anode chamber toward the cathode chamber, and allows ions such as chloride ions and sulfate ions to permeate from the cathode chamber toward the anode chamber. The so-called ion exchange membrane.

A flow path switching valve 26B is provided on the downstream side of the electrolytic cell 28. One of the flow path switching valves 26B connects one of the inlet nozzles corresponding to the electrolytic cell 28 to the electrolysis chamber, and one of the flow path switching valves 26B connects the outlet lines corresponding to the lines L3 and L4.

The flow path switching valve 26B is for switching the connection state of one of the electrolytic cells 28 to the electrolysis chamber and the lines L3, L4, and the operation thereof is controlled by the control unit 40. Specifically, the flow path switching valve 26B can be switched to the first connection state in which the second electrolysis chamber is connected to the line L4 while the first electrolysis chamber is connected to the line L3 by the control of the control unit 40. The first electrolysis chamber is connected to the line L4, and the second electrolysis chamber is connected to the second connection state of the line L3.

A flow control valve 27B is installed in the line L4. The flow control valve 27B is used as a throttle valve to lower the flow rate of the electrolytic acid water flowing in the line L4, which is controlled by the control unit 40. The interval between the flow rate control valve 27B and the flow rate control valve 27A is used to adjust the ratio of the generated electrolytic regenerated water to the electrolytic acid water, and the amount of electrolytic regenerated water is generated. It is also called a proportional adjustment valve when it is adjusted to a larger amount than the electrolytic acid water.

Further, on the downstream side of the position where the flow control valve 27B on the line L4 is installed, the check valve 22 is connected to the other end of the line L5 to which one end thereof is connected, and the other end of the line L5 is connected to the line L4. On the downstream side of the position, the centrifugal pump 30 is installed; and on the further downstream side of the position where the centrifugal pump 30 of the line L4 is installed, the other end of the line L6 to which the safety valve 20 is connected is connected.

The centrifugal pump 30 is driven to suck the cleaning liquid when performing the cleaning operation described later, and forcibly sends the cleaning liquid by discharging the cleaning liquid. This operation is controlled by the control unit 40. The suction port 30e1 of the centrifugal pump 30 is connected to the second discharge port 13a of the second drain pipe 13, and the discharge port 30e2 is connected to the electrolytic cell 28 (see Figs. 9A and 9B).

Here, in order to prevent the line L4 from being blocked during normal operation, it is assumed that the direction of the suction port 30e1 side of the centrifugal pump 30 toward the discharge port 30e2 side is positive, and the centrifugal pump 30 can stop the drive to bring the liquid toward the above forward direction. Conversely, the opposite direction circulates. Therefore, when the centrifugal pump 30 is installed in the line L4, the centrifugal pump 30 can be passed through to discharge the electrolytic acidic water.

The control unit 40 is configured by, for example, a CPU (Central Processing Unit), and mainly controls the operation of the entire electrolyzed water generating apparatus 1A. In more detail, as described above, the control unit 40 receives the input of the detection result by the flow detector 23, and controls the pair of flow path switching valves 26A, 26B, the pair of flow control valves 27A, 27B, the electrolytic cell 28, And the centrifugal pump 30 is activated. Further, the control unit 40 receives an instruction from the outside by the operation unit 14, and outputs the material that it should display in the display unit 15. Moreover, the control unit The 40 has a timer circuit for switching the operation state described later based on the data such as the operation time calculated by the timer circuit.

In the electrolyzed water generating apparatus 1A of the present embodiment as described above, the supply port 11a of the inlet pipe 11 passes through the relief valve 20, the purification processing unit 21, the check valve 22, the flow rate detector 23, and the branch line 24 The piping system of the portion from the flow path switching valve 26A to the electrolytic cell 28 corresponds to the introduction pipe for introducing the supplied raw water into the electrolytic cell 28, and the electrolytic cell 28 is connected to the first drainage pipe via the flow path switching valve 26B. The piping system of the first discharge port 12a of the 12th and the second discharge port 13a of the second drain pipe 13 corresponds to a discharge pipe that discharges the electrolytic reclaimed water and the electrolytic acid water derived from the electrolytic cell 28 to the outside.

Further, in the above-described outlet pipe, the flow path switching valve 26A passes through the line L3 and the portion from the first drain pipe 12 to the first discharge port 12a corresponds to the first discharge line; 26B corresponds to the second discharge line via the line L4 provided in the centrifugal pump 30 and the second drain pipe 13 to the second discharge port 13a, and the line L5 corresponds to the bypass pipe.

Further, the flow path switching valve 26A corresponds to the introduction pipe portion side connection state switching device; the flow path switching valve 26B corresponds to the outlet pipe portion side connection state switching device; the flow rate control valve 27A corresponds to the introduction pipe side flow rate adjustment device; and the flow rate control valve 27B corresponds to the outlet pipe side flow rate adjusting device.

Further, the control unit 40 corresponds to a switching control unit that simultaneously controls the relay and the pair of flow path switching valves 26A, 26B to make the polarity of the pair of electrolytic electrodes 28a, 28b, the pair of branch lines 24a, 24b, and a pair of electrolysis chambers Connection between the two, and the connection between a pair of electrolysis chambers and lines L3, L4 The status can be switched at the same time. As a result, in the normal operation of the electrolyzed water generating apparatus 1A of the present embodiment, the first operational state and the second operational state described below can be periodically and repeatedly switched.

Fig. 5 is a view showing a first operational state of the electrolyzed water generating apparatus shown in Fig. 1, and Fig. 6 is a schematic view showing a second operational state of the electrolyzed water generating apparatus shown in Fig. 1. Next, with reference to Fig. 5 and Fig. 6, in the electrolyzed water generating apparatus 1A of the present embodiment, the raw water in the first operating state and the second operating state in the operating state at the time of normal operation, the electrolytic reclaimed water, and the electrolytic acidic water are used. The flow direction is explained.

As shown in FIG. 5, in the first operational state, the raw water discharged from the faucet 100 is supplied to the inlet pipe 11 via the branch faucet 101, and the supplied raw water flows into the purification processing unit 21 via the relief valve 20. The raw water that has flowed into the purification processing unit 21 is removed and purified by purifying the filter element 21a, and is sent to the branch line 24 via the check valve 22 and the flow rate detector 23.

At this time, the control unit 40 receives the detection result of the flow rate detector 23 indicating the passage of the raw water, and applies a voltage between the pair of electrolytic electrodes 28a and 28b to perform electrolytic treatment in the electrolytic cell 28.

The raw water sent to the branch line 24 is adjusted and split at a specific ratio by the flow control valve 27A provided in the branch line 24b, and the separated raw water will pass through the branch lines 24a, 24b and the flow path. The switching valve 26A flows into the first electrolysis chamber and the second electrolysis chamber of the electrolytic cell 28. Further, the flow rate of the raw water flowing into the branch line 24b is adjusted to a flow rate smaller than that of the raw water flowing into the branch line 24a.

Here, in the first operational state, the pipeline system is switched to the first connected state. In other words, the branch line 24a is connected to the first electrolysis chamber by the flow path switching valve 26A, and the branch line 24b is connected to the second electrolysis chamber by the flow path switching valve 26A. Therefore, the raw water which is branched and flows into the branch line 24a is sent to the first electrolysis chamber, and the raw water which is branched and flows into the branch line 24b is sent to the second electrolysis chamber.

Next, the raw water sent to the electrolytic cell 28 is subjected to electrolytic treatment. At this time, in the first operational state, the first electrolysis chamber in which the electrolysis electrode 28a is disposed is used as the cathode chamber, and the second electrolysis chamber in which the electrolysis electrode 28b is disposed is used as the anode chamber. Therefore, in the first operational state, electrolytic regenerated water is generated in the first electrolysis chamber as the anode chamber, and electrolytic acidic water is generated in the second electrolysis chamber as the cathode chamber.

The raw water that has flowed into the purification processing unit 21 is removed and purified by purifying the filter element 21a, and is sent to the branch line 24 via the check valve 22 and the flow rate detector 23.

At this time, the control unit 40 receives the detection result of the flow rate detector 23 indicating the passage of the raw water, and applies a voltage between the pair of electrolytic electrodes 28a and 28b to perform electrolytic treatment in the electrolytic cell 28.

The raw water sent to the branch line 24 is adjusted and split at a specific ratio by the flow control valve 27A provided in the branch line 24b, and the separated raw water will pass through the branch lines 24a, 24b and the flow path. The switching valve 26A flows into the first electrolysis chamber and the second electrolysis chamber of the electrolytic cell 28. Further, the flow rate of the raw water flowing into the branch line 24b is adjusted to a flow rate smaller than that of the raw water flowing into the branch line 24a.

Here, in the second operational state, the pipeline system is switched to the second connected state. In other words, the branch line 24a is connected to the second electrolysis chamber by the flow path switching valve 26A, and the branch line 24b is connected to the first electrolysis chamber by the flow path switching valve 26A. Therefore, it flows in and out The raw water of the branch line 24a is sent to the second electrolysis chamber, and the raw water which is branched and flows into the branch line 24b is sent to the first electrolysis chamber.

Next, the raw water sent to the electrolytic cell 28 is subjected to electrolytic treatment. At this time, in the second operational state, the first electrolysis chamber in which the electrolysis electrode 28a is disposed is used as the anode chamber, and the second electrolysis chamber in which the electrolysis electrode 28b is disposed is used as the cathode chamber. Therefore, in the second operational state, electrolytic acid water is generated in the first electrolysis chamber as the cathode chamber, and electrolyzed reclaimed water is generated in the second electrolysis chamber as the anode chamber.

The electrolytically regenerated water and the electrolytically acidic water generated in the electrolytic cell 28 are discharged to the outside through the flow path switching valve 26B and the lines L3 and L4 from the first drain pipe 12 and the second drain pipe 13. Here, in the second operational state described above, the pipeline system is switched to the second connected state as described above. In other words, the first electrolysis chamber is connected to the line L4 by the flow path switching valve 26B, and the second electrolysis chamber is connected to the line L3 by the flow path switching valve 26B.

Therefore, the electrolytic acid water generated in the first electrolysis chamber is discharged into the electrolytic cell 28, and then flows into the line L4 via the flow path switching valve 26B, and thereafter, through the line L4, the flow rate control valve 27B provided therein, and the centrifugal The pump 30 is sent to the second drain pipe 13, and then discharged to the outside by the second drain pipe 13. Further, in Fig. 6, the electrolytic acidic water discharged from the second drain pipe 13 is indicated by reference numeral 32.

Fig. 7 is a schematic view showing the state of the electrolyzed water generating apparatus shown in Fig. 1 just after the water is stopped. Next, a state of drainage after the electrolyzed water generating apparatus 1A of the present embodiment has just stopped water will be described with reference to Fig. 7 . In addition, FIG. 7 is a schematic view showing the first connection state described above.

As shown in FIG. 7, when the supply of the raw water by the faucet 100 is stopped, the flow of the raw water in the flow detector 23 will also stop, and the control unit 40 receives the detection result of the flow detector 23 indicating that the raw water has not passed, The application of a voltage between the pair of electrolytic electrodes 28a and 28b is stopped to stop the electrolytic treatment performed in the electrolytic cell 28.

When the water is just stopped, the raw water, the electrolytic regenerated water, and the electrolytic acidic water in the piping system of the electrolysis water generating device 1A are moved into the pipeline according to the hydraulic head they have. At this time, if it is considered from the sanitary surface, it is preferable to discharge the raw water, the electrolytic regenerated water, and the electrolytic acidic water as much as possible without remaining inside the pipeline system.

In the electrolytically produced water device 1A of the present embodiment, the check valve 22 as the pressure relief valve is installed on the upstream side of the electrolytic cell 28, and when the water is stopped, the check valve 22 can be opened.

Therefore, as shown in Fig. 7, the water is regenerated by electrolysis mainly through the first drain pipe 12a, and the acid water and the raw water mainly passed through the second drain pipe 13a are discharged, respectively, to help reduce the residual in the pipeline system. .

In addition, the description of the details is omitted here, and even if the electrolytically produced water device 1A is in the second connection state, the flow of the raw water, the electrolytically regenerated water, and the electrolytic acidic water is substantially the same.

Fig. 8 is a view showing the state of cleaning operation of the electrolyzed water generating apparatus shown in Fig. 1. Next, a state in which the cleaning operation and the cleaning operation of the electrolytically produced water device 1A of the present embodiment are performed will be described with reference to Fig. 8 . In addition, FIG. 8 shows the first connection state described above.

As shown in Fig. 8, when the cleaning (i.e., removal of scale) of the electrolytic produced water apparatus 1A of the present embodiment is performed, a container 50 for storing the cleaning liquid 51 is prepared. Here, the cleaning liquid 51 is preferably a cleaning liquid containing a representative acid such as citric acid, acetic acid, ascorbic acid, succinic acid or malic acid which is effective for dissolving and removing scale, and particularly preferably has a specific concentration. Citric acid.

Further, the cleaning liquid 51 stored in the container 50 soaks the second drain port 13a of the second drain pipe 13, and the first drain port 12a of the first drain pipe 12 is provided directly above the container 50. At this time, in order to completely cover the second drain port 13a, it is preferable to install the foreign matter removing filter 52 composed of a net or the like. By installing the foreign matter removing filter 52, it is possible to prevent foreign matter from entering the inside of the electrolyzed water generating apparatus 1A during the cleaning operation described later.

After the above state, the operation state switching button installed in the operation unit 14 is input, and a command to start the cleaning operation is input to start the cleaning operation of the electrolysis water generating device 1A. Specifically, control unit 40 initiates actuation of centrifugal pump 30.

By driving the centrifugal pump 30, the cleaning liquid 51 stored in the container 50 is introduced into the line system of the electrolyzed water generating apparatus 1A via the second drain port 13a of the second drain pipe 13, and flows through a specific portion of the line system. Thereafter, the outside is discharged through the first drain port 12a of the first drain pipe 12. Further, the external cleaning liquid 51 is taken out through the first drain port 12a of the first drain pipe 12, Will return to the container 50.

More specifically, the cleaning liquid 51 is supplied to the line L4 via the second drain port 13a of the second drain pipe 13, and after passing through the centrifugal pump 30, a part thereof is branched to be introduced into the line L5, and the remaining portion is flow-through. The control valve 27B and the flow path switching valve 26B are introduced into the second electrolysis chamber of the electrolytic cell 28.

The cleaning liquid 51 introduced into the second electrolysis chamber flows through the second electrolytic cell, and is sent to the branch line 24 via the flow rate control valve 27A and the flow path switching valve 26A. On the other hand, the cleaning liquid 51 flowing into the line L5 flows into the line L2 via the check valve 22 in the open state, and is sent to the branch line 24 via the flow rate detector 23.

The cleaning liquid 51 that has reached the branch line 24 via the second electrolysis chamber and the cleaning liquid 51 that has reached the branch line 24 via the line L2 will be merged in the branch line 24, and then flow in through the flow path switching valve 26A. The first electrolysis chamber of the electrolytic cell 28. After flowing through the first electrolytic cell, the cleaning liquid 51 that has flowed into the first electrolytic cell reaches the first drain pipe 12 via the flow path switching valve 26A and the line L3, and is introduced into the container 50 through the first discharge port 12a.

In addition, the detailed description is omitted here, and even if the electrolysis water generating apparatus 1A is in the second connection state described above, the flow of the cleaning liquid 51 is substantially the same.

As described above, in the electrolyzed water generating apparatus 1A of the present embodiment, the cleaning liquid 51 can be circulated by the specific portion of the piping system installed inside, the first drain pipe 12, the second drain pipe 13, and the container 50. In addition, the cleaning liquid 51 can be circulated in the circulation circuit by driving the centrifugal pump 30 built in the apparatus body.

Here, the above-mentioned circulation circuit includes an electrolytic cell 28 located at a portion where scale adheres during normal operation, and a piping system on the downstream side thereof (especially The line connecting the electrolytic cell 28 and the flow path switching valve 26B, the flow path switching valve 26B, the line L3, the first drain pipe 12, and the like) are connected. Further, the above-mentioned circulation circuit includes, in addition, a pipeline system for measuring the downstream side of the electrolytic cell 28 where the scale is likely to adhere to the portion where the scale is adhered by the flow of the electrolyzed reclaimed water when the drainage operation is performed when the water is stopped ( In particular, the line connecting the electrolytic cell 28 and the flow path switching valve 26A, the flow path switching valve 26A, the line L2 including the portion where the flow rate detector 23 is provided, the line L5 of the bypass pipe, and the portion including the centrifugal pump 30 are provided.

Therefore, in the electrolyzed water generating apparatus 1A according to the embodiment of the present invention, the portion where all the scale may adhere is cleaned by the cleaning liquid 51 whose concentration can be adjusted, and the removal can be efficiently performed.

In addition, as described above, the cleaning operation for performing the cleaning does not require special installation of an additional cleaning filter element or the like, and only the operation unit 14 needs to be operated to prepare the cleaning liquid, which will be stored in the container, and in a predetermined state. The setting is carried out, so that it can be easily carried out, and it is also quite economically good.

Therefore, the electrolyzed water generating apparatus 1A according to the embodiment of the present invention is not only effective and easy to remove all parts where scale may be attached, but also an excellent electrolyzed water generating apparatus on the economical side.

Further, in the electrolyzed water generating apparatus 1A according to the embodiment of the present invention, since the line L5 having the bypass pipe can circulate more cleaning liquid 51 in a shorter time than when the bypass pipe is not provided. This is because when the bypass pipe is not provided, although it can be provided by the flow control valves 27A, 27B of the pipeline system, The flow rate of the cleaning liquid 51 is reduced. However, by providing the bypass pipe, the circulation circuit for circulating the cleaning liquid 51 can be configured without passing through the flow rate control valves 27A and 27B.

As shown in Fig. 10A, when the centrifugal pump 30 is disposed with the rotating shaft of the centrifugal pump 30 oriented in the horizontal direction, the position of the impeller 30c will be located in the residual water remaining in the pump chamber 30d of the centrifugal pump 30 when the water is stopped. Above the liquid level 200. Therefore, when this state is set, the impeller 30c may be rotated, but the water may not be pumped.

Fig. 10B is a schematic view showing the state of the centrifugal pump according to the second comparative example and the state of the centrifugal pump before the start of the washing operation. As shown in Fig. 10B, when the centrifugal pump 30 is disposed obliquely, according to the shape of the pump chamber 30d, when the water is stopped, the position of the impeller 30c will be located in the residual water remaining in the pump chamber 30d of the centrifugal pump 30. Above the face 200. Therefore, when this state is set, the impeller 30c may be rotated, but the water may not be pumped.

Figure 11 is a diagram showing the centrifugal pump in a variation of the embodiment. A schematic diagram of the state of the setting and the state of the centrifugal pump before the start of the cleaning operation. When the centrifugal pump 30 having the shape of the pump chamber 30d of the second comparative example described above is used, as shown in the drawing, the centrifugal pump 30 is disposed in the vertical direction with the rotating shaft of the centrifugal pump 30, which can be stopped. In the case of water, the position of the impeller 30c is located below the liquid level 200 of the residual water remaining in the pump chamber 30d.

As can be seen from the above, in order to smoothly and surely circulate the cleaning liquid 51 during the cleaning operation, the setting state of the centrifugal pump 30 is preferably substantially filled in the pump chamber 30d of the centrifugal pump 30 when the water is stopped. The state of the water is considered to be set.
