DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water treatment apparatus for passing raw water such as tap water, well water, and river water through an addition section filled with additives to elute the additives.

[0002]

2. Description of the Related Art Conventionally, there has been provided a water treatment apparatus for adding an additive such as minerals by passing raw water such as tap water, well water, and river water through an addition section filled with the additive. Also, an electrolyzed water generating apparatus that generates processing water such as alkaline ionized water or acidic water by electrolyzing water to which the additive is added has been provided.

A method of adding an additive such as a mineral to water has been disclosed in Japanese Patent Application Laid-Open No. 11-277079, and these methods use tap water or the like as it is or water from the tap water such as activated carbon. After removing the impurities in the water by passing through an adsorption purification section and a filter medium section such as a hollow fiber membrane,
This water is introduced into the additive section filled with the additive, and the additive in the water is generated by promoting the dissolution of the additive in water by dynamic contact between the running water and the additive in the additive section. Is what you do. The generated added water can be directly used for drinking and other uses, and an electrolytic cell is provided in the flow path on the downstream side of the adding section to perform electrolysis of water, such as alkali ion water, acidic water, etc. Also used to generate

[0004] Additives to be added to the addition portion are various shapes such as granules, pellets, powders, etc., and are used to promote dissolution and increase the amount of addition. An appropriate shape is selected so that the control and the like can be easily performed.

[0005] As a method of filling the additive portion with the additive,
Filling directly into the addition section installed in the water treatment device,
Alternatively, a member in which the additive is filled in the addition section is detachably formed with respect to the main body of the water treatment device, and the member in a state detached from the water treatment device is filled with the additive. The system is appropriately designed to be convenient for the user in consideration of the frequency of exchanging the additives.

[0006] Figs. 20 and 21 show a general structure of a conventional water treatment apparatus for adding an additive to raw water and performing electrolysis to generate alkaline ionized water or acidic water.

In the illustrated example, the electrolyzed water generator 301 includes an electrolyzer 302, a water purifier 303, an addition device 306, and the like. The electrolytic cell 302 is divided by the diaphragm 305 into an electrode chamber 314 in which the electrode 312A is arranged and an electrode chamber 318 in which the electrode 312B is arranged. Tap water, which is generally used as raw water, is supplied to an electrolytic cell 3 through a water purification device 303.
02 is introduced into the electrode chamber 314 and the electrode chamber 318. The water purification device 303 removes organic substances, inorganic substances, or odor components such as hypochlorous acid contained in tap water, and is usually constituted by a microfilter such as an antibacterial activated carbon filter or a hollow fiber membrane. In addition, the water purification device 30
The purified water flowing out of 3 is divided into an inflow path 322 directly communicating with the electrode chamber 318 and an inflow path 320 communicating with the electrode chamber 314. One inflow passage 322 has an addition device 306.
Is provided, and the additive is continuously supplied to the purified water flowing into one of the electrode chambers 318 by the addition device 306. Generally, calcium salts such as calcium lactate or calcium glycerophosphate are used as additives.

The water passed through the electrolytic cell 302 is supplied to the electrode 312
A, by conducting electricity between 312B and electrolyzing,
Alkaline ionized water is generated in the electrode chamber 314, and acidic water is generated in the electrode chamber 318. Cathode water is discharged from the outflow channel 323, and anode water is discharged from the outflow channel 321 through separate paths.

In FIG. 20, when the above-mentioned electrolyte is introduced into the electrode chamber 318, the electrolyte is directly mixed with the alkaline ionized water discharged from the electrolytic cypress 302, so that the electrolyte is added only to the water flowing into the electrode chamber 318. I am trying to do it. That is, the water to which the electrolyte is added is supplied to the electrode chamber 318.
In this way, only calcium ions are added to the alkaline ionized water, and lactate ions are discharged together with the acidic water. As a result, the alkaline ionized water mainly used for drinking or the like contains only calcium ions by electrophoresis by electrolysis. As a result, unnecessary electrolyte is not used, and particularly, the electric conductivity is 100 to 30.
In general tap water of about 0 μS / cm ² , the electrolyte can play a sufficient role for the purpose of promoting electrolysis by the so-called “anode addition method” described here.

On the other hand, tap water having an electric conductivity of 100 μS / cm ² or less, or tap water having a sufficient electric conductivity but containing a large amount of ionic species such as bicarbonate ions that buffer the electrolyzed water (particularly spring water) Etc.)
In such a case, a so-called “bipolar addition method” as shown in FIG. 21 may be used. This is because the above-mentioned electrolyte is introduced into both the electrode chamber 314 and the electrode chamber 318 to further increase the electric conductivity of the raw water to be used, so that the electrolytic current is more easily supplied to the raw water, and the efficiency of the electrolysis is improved. The above mentioned tap water having an electric motor rate of 100 μS / cm ² or less, or having sufficient electric conductivity,
Sufficient electrolysis can be performed even in the case of tap water containing a large amount of ionic species such as bicarbonate ions that buffer the electrolyzed water. Incidentally, in both FIGS.
Reference numerals 08A and 308B denote electrochemical water quality detectors, by which the quality of multipolar discharge water, such as pH, oxidation-reduction potential, calcium concentration, and electrical conductivity, can be known. Based on water quality measurement results from
Some can control electrolysis conditions such as electrolysis voltage and flow rate.

In the water treatment apparatus having the above-described configuration, as a method for controlling the amount of the additive to be added in the adding apparatus 306, a method disclosed in, for example, Japanese Patent Application Laid-Open No. 8-276192 is known. is there. In these conventional techniques, the amount of additive is controlled by changing the characteristics of water flowing into the addition device 306 to adjust the dissolution rate of the additive in water. Here, the characteristics of water include temperature, pressure, flow rate, pH, ORP (oxidation-reduction potential) and the like.

For example, in the case where the pH is changed as a characteristic of water, tap water is directly passed or water from the tap water is passed through an adsorption purification section such as activated carbon or a filter medium section such as a hollow fiber membrane to remove impurities in the water. After removing, it is introduced into an electrolytic cell to perform an electrolytic treatment. In the electrolytic cell, acidic water is generated from the anode side and alkaline ionized water is generated from the cathode side by the electrolytic treatment. In this case, for example, when calcium carbonate is used as an additive, the solubility of calcium carbonate changes depending on the pH of water. That is, when acidic water is used, calcium carbonate is dissolved in more water, and thus added water containing a higher concentration of additive can be obtained. The generated added water can be used directly for drinking and other purposes, or can be used to produce alkaline ionized water, acidic ionized water, etc. used.

[0013]

However, when the additive is added in the addition section, water is introduced into the addition section and the water is dynamically brought into contact with the additive in the addition section to add the additive to the water. Is dissolved, the additive amount of the additive is the flow rate of water introduced into the additive,
It depends on the amount of the additive filled in the addition part, and the amount of the additive contained in the water derived from the addition part varies depending on the conditions at that time.

Therefore, conventionally, in order to obtain a desired additive concentration, particularly when the additive concentration is required to be high, the user himself has to adjust the water amount by closing a water tap. In this case, the amount of water supplied to the water treatment device is limited.

In this case, if the user himself / herself knows in advance the amount of water that achieves the desired additive concentration, the amount of water can be set according to the additive concentration. The flow rate of the water supplied from the apparatus changes from time to time, and may differ from the amount of water desired by the user. At times, an excessive amount of water is supplied and unnecessary water is wasted. In some cases, too little water is supplied, and it takes too much time to obtain the required amount of water.

As described above, the method of controlling the amount of the additive by changing the characteristics of the water such as the pH of the water also requires that the substance used as the additive has a solubility of pH such as calcium carbonate. However, it does not depend only on the characteristics of water, such as those described above, and thus cannot be applied to various kinds of additives. In addition, even if the solubility of the additive is pH-dependent, in order to dissolve the additive so as to have the expected solubility, pH adjustment of water becomes very difficult, and it cannot be said that it is a simple method. Was something.

The present invention has been made in view of the above points, and controls the addition amount of an additive in an addition section irrespective of conditions such as a supply amount of raw water to be used and a quality of water to be used. An object of the present invention is to provide a water treatment apparatus capable of obtaining treated water having a desired agent concentration or the like.

Further, the present invention detects the water quality of the generated water, and changes the amount of a specific additive such as calcium ions dissolved according to the user's expectation based on the detection result of the water quality. It is another object of the present invention to provide a water treatment apparatus capable of performing the above-mentioned processes.

Embodiments of the present invention will be described below.

According to the present invention, the flow path between the raw water inlet and the discharge port is filled with an additive 103 therein, and the additive 103 is added to the water flowing from the inlet 101 and the water is discharged from the outlet. In the water treatment apparatus 1 provided with the addition unit 4 that flows out from the outlet 102, at least one of the inlet 101 and the outlet 102 is formed in a plurality, and at least one of the inlet 101 and the outlet 102 is further formed. A valve 104 for regulating the amount of water passing therethrough, or an opening 122 for selectively opening the flow of water at a specific one of the plurality of outlets 102 or the inlets 101, and a shield for shielding the flow of water 123 is provided.

Hereinafter, the configuration of the addition section 4 will be described first with reference to an embodiment.

In the first embodiment shown in FIG.
On one side of the container (addition cylinder 100) in which the addition tube 03 is filled, three inflow ports 101a, 101b, and 101c are formed vertically. Outlets 102a, 102b, 102c are formed. The three outlets 102a, 102b, 102c are respectively connected to the three inlets 101a, 101b, 101c.
Is formed slightly above the vertical arrangement position of.

The inflow passage 106 through which the water flowing into the addition section 4 passes
Is branched into three branch inflow paths 107, and each branch inflow path 107 is connected to each of the inlets 101a, 101b, 101c.
It is connected to the. The outflow channel 109 through which the water flowing out of the addition section 4 passes is provided with three outflow ports 102a, 102b,
Three branch outflow passages 108 connected to 102c are formed so as to merge on the downstream side. Each branch inflow path 107
A valve 104 for adjusting the amount of water is provided in each of the branch outflow passages 108, 108, and 108, whereby the amount of water passing through each of the inlet 101 and the outlet 102 is independently adjusted. As this valve 104, a throttle valve 105 that adjusts the amount of water by reducing the diameter of the flow path can be used.

In the addition section 4 configured as described above, the flow rate is controlled by each of the throttle valves 105 to open the flow of water at the lowermost inflow port 101a and to open the remaining inflow ports 101b and 101c. When the flow of water is interrupted, and the flow of water is opened at only one of the three outlets 102a, 102b, and 102c and the flow of water of the remaining is shut off, the addition cylinder is connected through the inlet 101a. The water that has flowed into the reservoir 100 accumulates in the addition cylinder 100, and when the water reaches the outlet 102 where the flow of the water is opened, the water flows out from the outlet 102. Therefore, when the flow of the water at the lowermost outlet 102a is released, the water and the additive 103 come into contact with each other in the region a in the drawing, and the flow of the water at the outlet 102b, which is one level above, is released. In the case of opening, the water and the additive 103 come into contact with each other in a region b in the figure, and when opening the flow of water in the uppermost outlet 102c, the water and the additive 103 are added in a region c in the diagram. The area in which the water and the additive 103 come into contact with each other increases as the outflow port 102 in which the agent 103 comes into contact and the flow of water is opened is disposed upward.

At this time, the additive 103 is dissolved in water in a region where the additive 103 comes into contact with water, and the dissolution of the additive 103 in water is longer as the time for which the additive 103 is in contact with water is longer. Since the time for interaction with water is long, the water is dissolved in a large amount. By adjusting the area where the water and the additive 103 come into contact with each other and changing the volume of the additive 103 in contact with the water in the addition cylinder 100 without changing the amount of water flowing through the addition section 4, The addition amount of 103 can be adjusted. When the addition cylinder 100 having the plurality of inlets 101 and the outlets 102 is used as described above, the additive that comes into contact with the inside of the addition cylinder 100 by adjusting the flow rate of water at the plurality of the inlets 101 and the outlets 102. The volume of 103 can be changed, which allows the amount of the additive 103 dissolved in water to be freely controlled.

The above operation is an operation in the case where the flow of water at the lowermost inlet 101a of the inlets 101 is released, but the flow of water at the other inlets 101b and 101c is opened. In this case, the addition amount of the additive 103 can be adjusted in more stages.

Although not shown in the figure, each throttle valve 10
When the driving device 71 for controlling the aperture amount of No. 5 is provided, the amount of the additive 103 to be added can be controlled by driving the driving device 71.

The second embodiment shown in FIG. 2 uses the on-off valve 110 as the valve 104 in two states, an open state for opening the flow of water and a closed state for shutting off the flow of water. The other configuration is the same as that of the first embodiment shown in FIG. As each of the on-off valves 110, an electromagnetic valve can be used, and an open state or a closed state is selected based on a control signal from the control circuit C.

In the adding section 4 configured as described above, under the control of the control circuit C, the flow of water is opened or shut off at each of the on-off valves 110 so that the water at the lowermost inflow port 101a is opened. Open the circulation and the remaining inlet 1
When the flow of water at the outlets 01b and 101c is shut off and the flow of water is opened at only one of the three outlets 102a, 102b and 102c and the flow of water of the remaining ones is shut off, the inlet Addition cylinder 10 from 101a
The water that has flowed into the chamber 0 accumulates in the addition cylinder 100, and when the water reaches the outlet 102 where the flow of water is opened, the water flows out from the outlet 102. For this reason, when the flow of the water at the lowermost outlet 102a is released, the water and the additive
When the water comes into contact with the additive 103 to release the flow of water from the outlet 102b, the water comes into contact with the additive 103 in the region b in the drawing, and the water from the uppermost outlet 102c. When the circulation is opened, the water and the additive 103 come into contact with each other in the region c in the drawing. The area where the agent 103 comes into contact increases.

At this time, the additive 103 is dissolved in water in a region where the additive 103 is in contact with water, and the dissolution of the additive 103 in water is longer as the time for which the additive 103 is in contact with water is longer. Since the time for interaction with water is long, a large amount of water is dissolved. Therefore, by opening or shutting off the water flow at each on-off valve 110, the opening position of the inlet 101 or the outlet 102 in the addition cylinder 100 can be changed. By adjusting the area where the water and the additive 103 come into contact with each other and adjusting the amount of water flowing through the addition
By changing the volume of the additive 103 which comes into contact with water by the above, the amount of the additive 103 to be added can be adjusted. As described above, the addition cylinder 10 having the plurality of inlets 101 and outlets 102
When 0 is used, a plurality of inlets 101 and outlets 102
It is possible to change the volume of the additive 103 in contact with the inside of the addition cylinder 100 by adjusting the flow rate of the water at this time, so that the amount of the additive 103 dissolved in water can be freely controlled. It becomes possible.

The above operation is an operation in the case where the flow of water at the lowermost inflow port 101a of the inflow ports 101 is released. In this case, the addition amount of the additive 103 can be adjusted in more stages.

In the third embodiment shown in FIG. 3, the opening diameters of the plurality of inlets 101 and outlets 102 are different. In the example shown in the drawing, the branch inflow pipe 107 has a pipe diameter gradually decreasing from a pipe arranged below to a pipe arranged above, so that the addition pipe 100 A plurality of formed inlets 101
The opening diameters of a, 101b, and 101c are gradually reduced from those formed below to those formed above. In addition, the branch outflow pipe 108 has a pipe diameter gradually increasing from a lower one to an upper one, and the branch outflow pipe 108 is formed in the addition cylinder 100 accordingly. The opening diameters of the plurality of outlets 102a, 102b, 102c are gradually increased from lower ones to upper ones. At this time, the opening diameters of the lowermost inlet 101a and the uppermost outlet 102c are formed to be substantially the same,
The opening diameter of the inlet 101b formed second from the bottom and the outlet 102b formed second from the top are substantially the same, and the inlet 101 arranged at the uppermost position is formed.
The opening diameter of the outlet 102a disposed at the lowermost position is substantially the same as that of the outlet c.

The other structure is the same as that shown in FIG.

In the addition section 4 thus formed, the flow of water is opened or shut off by the respective on-off valves 110 under the control of the control circuit C, so that the water at the lowermost inflow port 101a is opened. Open the circulation and the remaining inlet 1
When the flow of water at 01b and 101c is cut off, the flow of water at the lowest outlet 102a is opened, and the flow of water at the remaining outlets 102b and 102c is cut off.
The water that has flowed into the addition cylinder 100 from the inflow port 101a accumulates in the addition cylinder 100 and flows out from the outflow port 102a. The smallest and the inlet 1
01a, the amount of water flowing into the addition cylinder 100 and the amount of water flowing out of the addition cylinder 100 are equal to each other, even if the amount of water flowing out of the addition cylinder 100 is smaller than the flow rate of water passing through the inflow port 101a. The flow velocity of the water passing through “a” increases, and the pressure required when the water passes through the outlet 102 increases. For this reason, in the addition cylinder 100, the inflowing water reaches a position higher than the formation position of the outlet 102a in which the flow of the water is open, thereby increasing the pressure of the water passing through the outlet 102. At this time, water and the additive 103 come into contact with each other in a region indicated by a in the figure. Therefore, as compared with the case where the opening diameter of the outlet 102a is larger, the area where the water and the additive 103 come into contact is larger, and the amount of the additive 103 added is increased.

By controlling or controlling the control circuit C, the flow of water is opened or shut off at each of the on-off valves 110, so that the flow of water at the lowermost inlet 101a is opened and the remaining inlets are opened. When the flow of water at 101b, 101c is cut off, the flow of water at the uppermost outlet 102c is opened, and the flow of water at the remaining outlets 102a, 102b is cut off, the flow of water from the inlet 101a is stopped. 10
The water that has flowed into the nozzles 0 accumulates in the addition cylinder 100 and flows out of the outlet 102c. At this time, the opening diameter of the outlet 102c is the largest among the plurality of outlets 102, and Since the opening diameter of the inlet 101a is substantially the same, the flow velocity of the water passing through the inlet 101a is substantially equal to the flow velocity of the water passing through the outlet a. The required pressure is lower. For this reason, in the addition cylinder 100, the inflowing water reaches the formation position of the outlet 102c in which the flow of water is open, and does not enter above it. In the region shown by (1), water and the additive 103 come into contact. For this reason, compared with the case where the opening diameter of the outlet 102c is smaller, the contact between the water and the additive 103 becomes smaller, so that an excessive amount of the additive 103 can be prevented from being added.

The above operation is an operation in the case where the flow of water at the lowermost inflow port 101a of the inflow ports 101 is released, but the flow of water at the other inflow ports 101b and 101c is released. In this case, the addition amount of the additive 103 can be adjusted in more stages.

In the above example, the opening diameter of the inflow port 101 is made larger as it is formed upward, and the opening diameter of the outflow port 102 is made smaller as it is formed upward. However, when forming the plurality of inflow ports 101 and outflow ports 102 having different opening diameters, the formation positions of the inflow port 101 and the outflow port 102 are not limited to such a form.

In the fourth embodiment shown in FIG. 4, the opening diameters of a plurality of inlets 101 and outlets 102 are different. In the example shown in the drawing, the branch inflow pipe 107 has a pipe diameter that gradually increases from a pipe located below to a pipe placed above, so that the addition pipe 100 A plurality of formed inlets 101
The aperture diameters of a, 101b, and 101c are gradually increased from those formed below to those formed above. In addition, the branch outflow pipe 108 has a pipe diameter gradually increasing from a lower one to an upper one, and the branch outflow pipe 108 is formed in the addition cylinder 100 accordingly. The opening diameters of the plurality of outlets 102a, 102b, 102c are gradually increased from lower ones to upper ones. At this time, the opening diameters of the lowermost inflow port 101a and the lowermost outflow port 102c are formed substantially the same,
The opening diameter of the inlet 101b formed second from the bottom and the outlet 102b formed second from the bottom is substantially the same, and the inlet 101 arranged at the uppermost position is formed.
The opening diameter of the outlet 102a disposed at the uppermost position is substantially the same as that of the outlet c.

The other structure is the same as that shown in FIG.

In the addition section 4 thus formed, the flow of water is opened or shut off by the respective on-off valves 110 under the control of the control circuit C, whereby the water at the lowermost inlet 101a is opened. Open the circulation and the remaining inlet 1
When the flow of water at 01b and 101c is cut off, the flow of water at the lowest outlet 102a is opened, and the flow of water at the remaining outlets 102b and 102c is cut off.
Water that has flowed into the addition cylinder 100 from the inflow port 101a accumulates in the addition cylinder 100 and flows out of the outflow port 102a. At this time, the opening diameter of the outflow port 102a is smaller than that of the plurality of outflow ports 102. Therefore, even if the amount of water flowing into the addition cylinder 100 and the amount of water flowing out of the addition cylinder 100 are the same, the flow velocity of the water passing through the outlet 102a increases, and the outlet 102 The pressure required when passing through increases. For this reason, the addition cylinder 10
In 0, the inflowing water reaches above the formation position of the outlet 102a in which the flow of the water is open, thereby ensuring the pressure of the water to pass through the outlet 102. At this time, water and the additive 103 come into contact with each other in a region indicated by a in the drawing. For this reason, compared with the case where the opening diameter of the outlet 102a is large, the area where the water and the additive 103 come into contact with each other becomes large, and the additive 10
3, the amount of addition increases.

Further, by controlling or controlling the control circuit C, the flow of water is opened or shut off at each of the on-off valves 110, so that the flow of water at the lowermost inlet 101a is opened and the remaining inlets are opened. When the flow of water at 101b, 101c is cut off, the flow of water at the uppermost outlet 102c is opened, and the flow of water at the remaining outlets 102a, 102b is cut off, the addition cylinder is connected from the inlet 101a. 10
The water that has flowed into the nozzles 0 accumulates in the addition cylinder 100 and flows out of the outlet 102c. At this time, since the opening diameter of the outlet 102a is the largest among the plurality of outlets 102, The pressure required when water passes through outlet 102 is reduced. For this reason, in the addition cylinder 100, the inflowing water reaches the formation position of the outlet 102a where the flow of the water is open, and at this time, in the region shown by b in FIG. 103 comes into contact. For this reason, compared with the case where the opening diameter of the outlet 102c is smaller, the contact between the water and the additive 103 becomes smaller, so that an excessive amount of the additive 103 can be prevented from being added.

The above operation is an operation when the flow of water at the lowermost inlet 101a of the inlets 101 is released, but the flow of water at the other inlets 101b and 101c is opened. In this case, the addition amount of the additive 103 can be adjusted in more stages.

In the fifth embodiment shown in FIG. 5, the plurality of inlets 101 and outlets 102 have different opening diameters. In the example shown in the drawing, the branch inflow pipe 107 has a pipe diameter gradually decreasing from a pipe arranged below to a pipe arranged above, so that the addition pipe 100 A plurality of formed inlets 101
The opening diameters of a, 101b, and 101c are gradually reduced from those formed below to those formed above. Further, the branch outflow pipe 108 has a pipe diameter gradually decreasing from a pipe disposed below to a pipe disposed above, and is formed in the addition pipe 100 accordingly. The opening diameters of the plurality of outlets 102a, 102b, 102c are gradually reduced from the lower one to the upper one. At this time, the opening diameters of the lowermost inflow port 101a and the lowermost outflow port 102c are formed substantially the same,
The opening diameter of the inlet 101b formed second from the bottom and the outlet 102b formed second from the bottom is substantially the same, and the inlet 101 arranged at the uppermost position is formed.
The opening diameter of the outlet 102a disposed at the uppermost position is substantially the same as that of the outlet c.

The other structure is the same as that shown in FIG.

In the addition section 4 thus formed, the flow of water is opened or shut off at each of the on-off valves 110 under the control of the control circuit C, so that the water at the lowermost inflow port 101a is opened. Open the circulation and the remaining inlet 1
When the flow of water at 01b and 101c is cut off, the flow of water at the lowest outlet 102a is opened, and the flow of water at the remaining outlets 102b and 102c is cut off.
Water that has flowed into the addition cylinder 100 from the inflow port 101a accumulates in the addition cylinder 100 and flows out of the outflow port 102a. At this time, the opening diameter of the outflow port 102a is smaller than that of the plurality of outflow ports 102. Largest and inlet 1
01a is substantially the same as the opening diameter of the inlet 101a.
And the flow rate of the water passing through the outlet a becomes substantially equal, and the pressure required when the water passes through the outlet 102 decreases. For this reason, in the addition cylinder 100, the inflowing water reaches the formation position of the outlet 102a where the flow of the water is open, and does not enter above it.
In the region shown in FIG.
For this reason, compared with the case where the opening diameter of the outlet 102a is smaller, the area where the water and the additive 103 come into contact is smaller, and the lower limit of the addition amount can be reduced.

Further, by controlling or controlling the control circuit C, the flow of water is opened or shut off at each of the on-off valves 110, so that the flow of water at the lowermost inlet 101a is opened and the remaining inlets are opened. When the flow of water at 101b, 101c is cut off, the flow of water at the uppermost outlet 102c is opened, and the flow of water at the remaining outlets 102a, 102b is cut off, the addition cylinder is connected from the inlet 101a. 10
The water that has flowed into the nozzles 0 is accumulated in the addition cylinder 100 and flows out of the outlet 102c. At this time, the opening diameter of the outlet 102c is the smallest among the plurality of outlets 102, and Even if the amount of water flowing into the addition cylinder 100 and the amount of water flowing out of the addition cylinder 100 are the same because the inlet is smaller than the inlet 101a, the flow velocity of the water passing through the outlet 102c increases, and the outlet 102c The pressure required when water passes through is increased. For this reason, in the addition cylinder 100, the inflowing water reaches a position higher than the formation position of the outlet 102c in which the flow of the water is open, thereby increasing the pressure of the water passing through the outlet 102c. At this time, water and the additive 103 come into contact with each other in a region indicated by b in the drawing. For this reason, compared with the case where the opening diameter of the outlet 102c is larger, the area where the water and the additive 103 come into contact with each other becomes larger,
As a result, in adjusting the amount of additive based on the difference in height between the plurality of outlets 102, the width of the additive concentration that can be adjusted is greater than when a plurality of outlets 102 having the same diameter are provided. Is larger.

The above operation is an operation in the case where the flow of water at the lowermost inlet 101a of the inlets 101 is released, but the flow of water at the other inlets 101b and 101c is opened. In this case, the addition amount of the additive 103 can be adjusted in more stages.

In the sixth embodiment shown in FIG.
However, the addition cylinder 100 in which at least one of the inflow port 101 and the outflow port 102 is formed, and a shield that can move water to one of the plurality of inflow ports 101 or the outflow port 102 by moving the addition pipe 100 It is composed of a member 111. In the illustrated example, a hollow portion 115 filled with the additive 103 is formed inside the addition cylinder 100,
An inflow port 101 is formed below the hollow portion 115, and the inflow port 101 is connected to an inflow path 106 through which water flowing into the addition section 4 passes. On the side surface of the addition cylinder 100, three outflow ports 102a, 102b, 102c are formed in a line in the vertical direction. The outflow passage 109 through which the water flowing out of the addition section 4 passes is provided at each of the three outflow ports 1.
Three branch outflow passages 108 through which the water flowing through 02a, 102b, and 102c pass are formed so as to merge on the downstream side. The three branch outflow passages 108 are formed so as to extend laterally from the addition cylinder 100, and are provided between an end opening of each branch outflow passage 108 and each of the branch flow passages 108 and the corresponding outlet 102. Is formed with a gap.

The shielding member 111 is connected to the branch flow path 108.
In addition to being slidably in contact with the side surface of the addition cylinder 100 while being interposed between the end opening of the addition cylinder and the outlet 102, it is formed to be slidable vertically along the side surface of the addition cylinder 100. The shielding member 111 has one opening 1 having a shape matching the end opening of the branch flow passage 108 and the outlet 102.
12 is formed, and a portion above and below the opening 112 is formed as a shielding portion 113 for shielding the branch flow path 108 and the outlet 102.

When the shielding member 111 is slid in the vertical direction, the position of the opening 112 is displaced in the vertical direction.
Is arranged between the end opening and the outlet 102, the branch outlet 108 and the outlet 102 communicate with each other, and the outlet 1
The water flow in 02 is released. Further, a shielding portion 113 is provided between the other branch outflow passage 108 and the outlet 102.
Is arranged, the communication between the branch outflow passage 108 and the outlet 102 is prevented, and the flow of water at the outlet 102 is blocked. For this reason, the shielding member 11
1 by sliding the opening 112 and the shielding 113.
By displacing the position, the outlet 102 from which the flow of water is opened can be changed.

In the addition section 4 formed in this way, the three outflow ports 102a, 102b, 10
When the flow of the water is opened in only one of the 2c and the flow of the remaining water is cut off, the water flowing into the addition cylinder 100 from the inflow port 101a is added to the addition cylinder 10c.
When the water reaches the outlet 102 where the flow of the water is opened, the water flows out from the outlet 102. For this reason, for example, when the flow of water at the lowermost outlet 102a is opened, the water and the additive 103 come into contact with each other in the area a in the figure, and the flow of water at the uppermost outlet 102c is opened. If so, b in the figure
In this region, the water comes into contact with the additive 103, and the closer the outflow port 102 in which the flow of water is opened is located, the larger the region in which the water comes into contact with the additive 103.

At this time, the additive 103 is dissolved in water in a region where the additive 103 is in contact with water, and the dissolution of the additive 103 in water is longer as the time for which the additive 103 contacts the water is longer. Since the interaction time with water increases, a large amount of water is dissolved. Therefore, by sliding the shielding member 111, the opening position of the outlet 102 in the addition cylinder 100 is adjusted, and the water and the additive 103 are adjusted. The contact area of the additive 10 with the water in the addition cylinder 100 can be adjusted without changing the amount of water flowing through the addition section 4 by adjusting the area where the
By changing the volume of No. 3, the amount of the additive 103 can be adjusted.

The opening 112 of the shielding member 111 is
The end opening of one of the branch outflow passages 108 and the outlet 102
In this state, the shielding member 111 is slid in the vertical direction from a state in which the positional relationship between the opening 112 and the end opening of the branch outflow passage 108 or the outlet 102 is completely matched. By displacing the position of the opening 112, the outlet 102 is partially closed, and the cross-sectional area of the flow path between the end opening of the branch outflow passage 108 and the outlet 102 can be reduced. By doing so, the flow rate of water between the outlet 102 in which the flow of water is opened and the branch outflow passage 108 connected to the outlet 102 increases,
The pressure required when water passes through the outlet 102 increases. For this reason, in the addition cylinder 100,
The inflowing water is supplied to the outlet 102 in which the water flow is open.
By reaching the position above the formation position of water, the pressure of water for passing through the outlet 102 is ensured. Therefore, the area where the water comes into contact with the additive 103 becomes larger, The added amount of 103 increases. Also, the amount of increase in the area where the water comes into contact with the additive 103 is determined by the sliding movement of the shielding member 111.
By adjusting the cross-sectional area of the flow path between the end opening of FIG. 8 and the outlet 102, it is possible to continuously change the flow rate. It can be changed to.

Although not shown in the figure, the shielding member 11
When a driving device 71 that slides 1 vertically is provided, the amount of the additive 103 added can be controlled by driving the driving device 71.

In the seventh embodiment shown in FIG.
However, the addition cylinder 100 in which at least one of the inflow port 101 and the outflow port 102 is formed, and a shield that can move water to one of the plurality of inflow ports 101 or the outflow port 102 by moving the addition pipe 100 A plurality of inlets 101 or outlets 1
02 is formed so as to be arranged in the horizontal direction. In the illustrated example, the addition cylinder 100 is formed in a vertical cylindrical shape. Although not shown, an inflow port 101 is formed on a side surface of the addition cylinder, and an inflow path 106 through which water flowing into the addition section 4 passes is connected to the inflow port 101.
Also, at the lower part of the side surface of the addition cylinder 100, three outlets 10
2a, 102b, and 102c are formed in a line in the horizontal direction, and each of the outlets 102 is an inlet from the one formed at one end to the one formed at the other end. It is formed so that the distance from 101 is long. Outflow channel 1 through which water flowing from addition section 4 passes
09 indicates three outlets 102a, 102b, 102c.
Are formed so that the three branch outflow passages 108 through which the water flowing through the water flows can merge on the downstream side. Three branch outflow channels 10
8 is formed so as to extend laterally from the addition cylinder 100, and is provided with an end opening of each branch outflow passage 108 and the branch flow passage 1.
A gap is formed between the discharge port 08 and the corresponding outlet 102.

The shielding member 111 is formed in a plate shape that is long in the lateral direction and is curved in a shape following the shape of the side peripheral surface of the addition cylinder 100. It is slidably in contact with the side peripheral surface of the addition cylinder 100 while being interposed between the outlet 102 and slidably formed in the lateral direction along the side peripheral surface of the addition cylinder 100. The shielding member 111 has one opening 112 that matches the end opening of the branch flow path 108, and one side and the other side of the opening 112 are the shielding parts 11 that shield the branch flow path 108.
3 is formed.

When the shielding member 111 is slid laterally along the peripheral surface of the adding cylinder 100, the opening 112
Is displaced laterally, and when this opening 112 is disposed between the end opening of one of the branch outflow passages 108 and the outlet 102, the branch outflow passage 108 and the outlet 10
2 communicates with each other, and the flow of water at the outlet 102 is released. In addition, the other branch outflow passage 108 and outlet 102
The shielding portion 113 is disposed between the two, and the communication between the branch outflow passage 108 and the outlet 102 is prevented, and the flow of water at the outlet 102 is blocked.
For this reason, by sliding the shielding member 111 and displacing the arrangement position of the opening 112, the outlet 102 through which the flow of water is released can be changed.

In such an addition section 4, the shielding member 111
When the outlet 102 through which the flow of water is opened is changed by sliding and adjusting the arrangement position thereof,
The longer the distance between the inflow port 101 and the outflow port 102 through which the water is opened, the longer the contact time of the additive 103 with water, and the longer the interaction time between the additive 103 and water. The agent 103 is dissolved in a large amount, and therefore, by sliding the shielding member 111,
The opening position of the outlet 102 in the addition cylinder 100 is adjusted so that the outlet 101 and the outlet 102 through which the flow of water is opened.
Is changed without changing the amount of water flowing through the addition unit 4 without changing the amount of water flowing through the addition unit 4.
By changing the volume of No. 3, the amount of the additive 103 can be adjusted.

Although not shown in the figure, the shielding member 11
When a driving device 71 that slides 1 along the peripheral surface is provided, the amount of the additive 103 added can be controlled by driving the driving device 71.

In the eighth embodiment shown in FIG.
Is composed of a main body 115 and a filling container 116, and the filling container 116 also has a function as a shielding member 111.

The main body 115 is formed in a vertical cylindrical shape, and the inside of the main body 115 is formed as an arrangement recess 121. The lower end surface of the arrangement concave portion 121 is closed and an inflow port 101 is formed. The inflow port 101 is provided with an inflow passage 10 through which water flowing into the addition section 4 passes.
6 is connected. The upper end surface of the arrangement recess 121 is open. In addition, four outlets 102 are formed in a line in the vertical direction on the side surface of the filling container 116, and the outlets 102 communicate with the inside of the arrangement recess 121. The outflow channel 109 through which the water flowing out of the addition section 4 passes is formed such that the four branch outflow channels 108 connected to the four outflow ports 102a, 102b, 102c, and 102d join on the downstream side. .

On the other hand, the filling container 116 (shielding member 111)
Is formed in a vertical cylindrical shape having an upper surface opened and a lower surface closed. The outer diameter of the filling container 116 is substantially the same as or slightly smaller than the inner diameter of the arrangement concave portion 121,
It is removably arranged in the arrangement recess 121 of the main body 115. When the filling container 116 is arranged in the arrangement concave portion 121, the outer peripheral surface of the filling container 116 is in sliding contact with the inner peripheral surface of the arrangement concave portion 121. Although not shown, an opening communicating with the inflow port 101 is formed in the filling container 116, and this opening is covered with a mesh. Four openings 112 are formed in the peripheral wall of the filling container 116 to communicate the inside and the outside of the filling container 116. The openings 112 are formed side by side in a direction inclined with respect to the center axis of the filling container 116 in the up-down direction. They are formed at the same position. In the peripheral wall of the filling container 116, a region other than the region where the opening 112 is formed is formed as a shielding portion 113.

The filling container 116 is removably disposed in the disposing recess 121 in a state where the additive 103 (not shown) is filled therein, thereby forming the adding portion 4. The container 116 and the main body 115 are rotatable about a vertical axis.

In the adding section 4 configured as described above, when at least one of the filling container 116 and the main body 115 is rotated about the center axis in the vertical direction, the main body 11
The position of the opening 112 of the filling container 116 is displaced in the circumferential direction with respect to 5, so that the arrangement position of any one of the four openings 112 is changed to the arrangement position of the corresponding outlet 102. By matching, the flow of water at the outlet 102 can be released. At this time, the other outlet 1
02 is the peripheral surface of the filling container 116 (that is, the shielding portion 11
It is closed by 3) and the flow of water is blocked. For this reason, at least one of the filling container 116 and the main body 115 is rotated about the vertical center axis to displace the position of the opening 112, so that the outlet 102 through which the flow of water is opened is opened. Can be changed.

In the addition section 4 formed as described above, at least one of the filling container 116 and the main body 115 is rotated about the center axis in the vertical direction, so that the four outlets 102a, 102b, 102c are provided. , 102d, when the flow of water is opened and the flow of water of the other is shut off, the inlet 101
The water that has flowed into the filling container 116 from the above accumulates in the filling container 116, and when the water reaches the outlet 102 where the flow of the water is opened, the water flows out from the outlet 102. For this reason, for example, the lowermost outlet 10
When the flow of the water 2a is opened, the water and the additive 103 come into contact with each other in the region a in the drawing, and when the flow of the water at the uppermost outlet 102d is opened, the flow of the b Water and the additive 103 come into contact in the region of
The area where the water and the additive 103 come into contact with each other increases as the outlet 102 in which the flow of the water is opened is disposed upward.

At this time, the additive 103 is dissolved in water in a region where the additive 103 comes into contact with water, and the dissolution of the additive 103 in water is longer as the time for which the additive 103 is in contact with water is longer. Since the interaction time with water is long, a large amount of water is dissolved. Therefore, by rotating at least one of the filling container 116 and the main body 115 about the center axis in the vertical direction, the outlet 102 Is adjusted to adjust the area where water and the additive 103 come into contact with each other, without changing the amount of water flowing through the addition section 4.
The amount of the additive 103 added can be adjusted by changing the volume of the additive 103 that comes into contact with water.

The filling container 116 (shielding member 111)
When one of the openings 112 is aligned with the corresponding outlet 102, the filling container 116 is rotatable with respect to the main body 115 from the state where the positional relationship between the opening 112 and the outlet 102 is completely matched. The opening 1
12 can be displaced to partially close the outlet 102, and the cross-sectional area of the flow path between the end opening of the branch outlet 108 and the outlet 102 can be reduced. In this way, the outlet 102 in which the flow of water is opened and the outlet 1
The flow velocity of the water between the branch outflow passage 108 connected to the outlet port 02 and the water is increased, and the pressure required when the water passes through the outlet 102 increases. For this reason, the addition cylinder 10
In 0, the inflowing water secures the pressure of the water to pass through the outlet 102 by reaching the position above the formation position of the outlet 102 where the flow of the water is open. Therefore, the area where the water and the additive 103 come into contact with each other becomes larger, and the amount of the additive 103 added increases. Further, the amount of increase of the area where the water comes into contact with the additive 103 adjusts the cross-sectional area of the flow path between the end opening of the branch outflow passage 108 and the outlet 102 by the rotational movement of the shielding member 111. Thus, the amount of the additive 103 dissolved in water can be changed continuously.

In the above example, the positions of the plurality of outlets 102 and the openings 122 corresponding to the outlets 102 are different.
The positional relationship with the arrangement position is formed such that the distance from the outlet 102 to the opening 122 in the direction of displacement of the opening 122 due to the movement of the shielding member 111 is gradually increased. That is, in the example shown in FIG. 8 described above, the outflow port 102 is formed in a line in the upper and lower direction along the direction of the rotation axis of the filling container 116 with respect to the main body 115, whereas the opening 112 is The openings 112 are formed side by side along the direction inclined with respect to the rotation axis. At this time, between the adjacent openings 112, the arrangement position of one of the openings 112 is changed from the arrangement position of the other opening 112 to the filling container. 11
6 and at a position displaced in the rotation axis direction of the filling container 116. That is,
The distance between each of the openings 112 and the corresponding outlet 102 in the direction of displacement of the openings 112 is sequentially increased by the amount of displacement in the circumferential direction. For this reason, when the position of the opening 112 is displaced by rotating the filling container 116, each opening 112 sequentially matches the corresponding outlet 102, and at this time, one of the sets Inlet 102 and opening 112
Only matches.

Therefore, when the opening 112 that matches the outlet 102 is changed by rotating the filling container 116, it is possible to prevent a situation in which none of the openings 112 matches the outlet 102. It is possible to prevent the outflow of water at any of the outlets 102 regardless of the inflow of water from the inflow port 101 to the addition section 4 and prevent an abnormal pressure from being applied to the inside of the addition section 4. In addition, even when the amount of the additive 103 added in the filling section 4 is adjusted, the water can be smoothly discharged from the adding section 4.

Further, one of the openings 112 is connected to the outlet 1
02, the other outlets 102 are shielded by the shielding portion 113, the plurality of openings 112 do not match the outlets 102, and the amount of additive 103 added is switched. Can be performed step by step.

In the above description, the filling container 116 in FIG.
6, a plurality of openings 112 and shielding portions 113 are formed,
Although the plurality of outlets 102 are formed in the main body 115, the plurality of openings 112 of the filling container 116 are regarded as the outlets 102, and the plurality of outlets 102 of the main body 115 are formed.
May be regarded as the opening 112, the side peripheral wall of the main body 115 may be regarded as the shielding 113, and the main body 115 may be the shielding member 111. Also in this case, by rotating the main body 115 with respect to the filling container 116, any one of the plurality of openings 112 of the main body 115 is aligned with the corresponding outlet 102, as described above. Then, the flow of the water at the outlet 102 is opened, and the other outlets 102 are shielded by the shielding portion 113 to block the flow of the water, and the flow of the water at the plurality of outlets 102 is selectively opened. It is recognized that we can do it.

Although not shown in FIG.
When the driving device 71 for rotating the drive 1 is provided, the amount of the additive 103 added can be controlled by driving the driving device 71.

In the ninth embodiment shown in FIG.
Is composed of a main body 115 and a filling container 116, and the filling container 116 also has a function as a shielding member 111.

The main body 115 is formed in a vertical cylindrical shape, and the inside of the main body 115 is formed as an arrangement recess 121. The lower end surface of the arrangement concave portion 121 is closed and an inflow port 101 is formed. The inflow port 101 is provided with an inflow passage 10 through which water flowing into the addition section 4 passes.
6 is connected. The upper end surface of the arrangement recess 121 is open. In addition, four outlets 102 are formed on the side surface of the main body 115 in a line in the vertical direction. The outflow channel 109 through which the water flowing out of the addition section 4 passes is formed such that the four branch outflow channels 108 connected to the four outflow ports 102a, 102b, 102c, and 102d join on the downstream side. .

On the other hand, the filling container 116 (shielding member 111)
Is formed in a vertical cylindrical shape having an upper surface opened and a lower surface closed. The outer diameter of the filling container 116 is substantially the same as or slightly smaller than the inner diameter of the arrangement concave portion 121,
It is removably arranged in the arrangement recess 121 of the main body 115. At this time, when the filling container 116 is arranged in the arrangement concave portion 121, the outer peripheral surface of the filling container 116 comes into sliding contact with the inner peripheral surface of the arrangement concave portion 121. Although not shown, an opening communicating with the inflow port 101 is formed in the filling container 116, and this opening is covered with a mesh. In addition, the filling container 11
6 has a slit-like opening 112 for communicating the inside and the outside with each other.
Are formed. The opening 112 is provided in the filling container 11.
6 is formed in a direction inclined with respect to the vertical center axis, and is formed in a spiral winding from the upper end side to the lower end side of the filling container 116. Further, the area of the filling container 116 other than the area where the opening 112 is formed is
3 is formed.

The filling container 116 is arranged in the disposing recess 121 with the additive 103 (not shown) being filled therein, thereby forming the adding section 4. The main body 115 is rotatable with respect to a vertical axis.

In the addition section 4 configured as described above, when at least one of the filling container 116 and the main body 115 is rotated about the center axis in the vertical direction, the main body 11
5, the position of the opening 112 of the filling container 116 is displaced in the circumferential direction, whereby the slit-like opening 112 is displaced.
The arrangement position of some of the regions is matched with the arrangement position of any one of the outlets 102, and the flow of water at the outlet 102 can be released. At this time, the other outlet 102 is closed by the peripheral surface of the filling container 116 (that is, the shielding portion 113), and the flow of water is shielded. For this reason, at least one of the filling container 116 and the main body 115 is rotated around a vertical central axis to displace the position of the opening 112,
The outlet 102 from which the flow of water is opened can be changed.

In the addition section 4 formed as described above, at least one of the filling container 116 and the main body 115 is rotated about a vertical central axis, so that the four outlets 102a, 102b, 102c are formed. , 102d, the flow of water is opened and the flow of water of the other is shut off, and
The water that has flowed into the filling container 116 from the above accumulates in the filling container 116, and when the water reaches the outlet 102 where the flow of the water is opened, the water flows out from the outlet 102. For this reason, for example, the lowermost outlet 10
When the flow of the water 2a is opened, the water and the additive 103 come into contact with each other in the area a in the figure, and when the flow of the water of the outlet 102 arranged further upward is opened, the water The region where the water and the additive 103 come into contact with each other is increased, and the region where the water and the additive 103 come into contact with each other is increased as the outlet 102 with the open water flow is disposed upward.

At this time, the dissolution of the additive 103 in water is performed in a region where the additive 103 comes into contact with water. Since the interaction time with water is long, a large amount of water is dissolved. Therefore, by rotating at least one of the filling container 116 and the main body 115 about the center axis in the vertical direction, the outlet 102 Is adjusted to adjust the area where water and the additive 103 come into contact with each other, without changing the amount of water flowing through the addition section 4.
The amount of the additive 103 added can be adjusted by changing the volume of the additive 103 that comes into contact with water.

The filling container 116 (shielding member 111)
Some area of the opening 112 of any one of the outlets 102
When the filling container 116 is rotated with respect to the main body 115 from a state where the positional relationship between the opening 112 and the outlet 102 is completely matched, the opening 1
12 can be displaced to partially close the outlet 102, and the cross-sectional area of the flow path between the end opening of the branch outlet 108 and the outlet 102 can be reduced. In this way, the outlet 102 in which the flow of water is opened and the outlet 1
The flow velocity of the water between the branch outflow passage 108 connected to the outlet port 02 and the water is increased, and the pressure required when the water passes through the outlet 102 increases. For this reason, the addition cylinder 10
In 0, the inflowing water secures the pressure of the water to pass through the outlet 102 by reaching the position above the formation position of the outlet 102 where the flow of the water is open. Therefore, the area where the water and the additive 103 come into contact with each other becomes larger, and the amount of the additive 103 added increases. The amount of increase in the area where the water comes into contact with the additive 103 adjusts the cross-sectional area of the flow path between the end opening of the branch outflow passage 108 and the outlet 102 by sliding movement of the shielding member 111. Thus, the amount of the additive 103 dissolved in water can be changed continuously.

It is preferable that the longitudinal direction of the slit-shaped outlet 102 and the arrangement direction of the plurality of openings 122 are formed so as to be inclined with respect to each other. In the example shown in FIG. 9 described above, the outlets 102 are formed in a line in the upper and lower rows along the direction of the rotation axis of the filling container 116 with respect to the main body 115, whereas the longitudinal direction of the opening 112 is Are formed in a direction inclined with respect to the rotation axis of the rotator. Therefore, when the position of the opening 112 is displaced by rotating the filling container 116, the opening 112 is
The plurality of outflow ports 102 are sequentially matched, and at this time, only one of the inflow ports 102 completely matches the opening 112.

Therefore, when the opening 112 that matches the outlet 102 is changed by rotating the filling container 116, it is possible to prevent a situation in which none of the openings 112 match the outlet 102. It is possible to prevent the outflow of water at any one of the outlets 102 regardless of the flow of water from the inlet 101 to the addition unit 4, thereby preventing abnormal pressure from being applied to the addition unit 4. In addition, even when the amount of the additive 103 added in the filling section 4 is adjusted, the water can be smoothly discharged from the adding section 4.

Further, any one of the outlets 102 has the opening 1
12, the other outlets 102 are shielded by the shielding portion 113, and the plurality of outlets 102 do not match the openings 112, and the amount of the additive 103 added is switched. Can be performed step by step.

Although not shown in FIG.
When the driving device 71 for rotating the drive 1 is provided, the amount of the additive 103 added can be controlled by driving the driving device 71.

In the example shown in FIGS.
2 are formed, but a plurality of inlets 101 may be formed. In this case, an opening 112 for opening the flow of water at one of the plurality of inlets 101 and another inlet Shielding part 113 for shielding the flow of water in 101
Is provided.

FIG. 10 shows a tenth embodiment, in which the respective amounts of inflow water flowing into the addition section 4 from the inlet 101 and outflow water flowing out of the addition section 4 from the outlet 102 are adjusted. As the valve 104, a throttle valve 105 that adjusts the amount of water by narrowing the diameter of the flow path is used.

In the illustrated example, one inlet 1 is provided at the lower part of one side of the container (addition cylinder 100) in which the additive 103 is filled.
01 is formed, and an inflow passage 106 through which water flowing into the addition section 4 passes is connected to the inflow port 101. On the other side of the addition cylinder 100, three outflow ports 102 arranged vertically
a, 102b, and 102c are formed, and the outflow passage 109 through which the water flowing out of the addition section 4 passes is connected to each of the three outlets 1
Three branch outflow passages 108 connected to 02a, 102b, and 102c are formed so as to merge on the downstream side.
A water channel 106 and each of the three branch outlet channels 108, 108,
Each of the throttle valves 108 is provided with a throttle valve 105, whereby the amount of water passing through each of the inlets 101 and the outlets 102 is independently adjusted.

In the addition section 4 configured as described above, the flow rate is controlled by each throttle valve 105, so that the inflow port 10 is controlled.
1 to open the flow of water and at the same time
When the flow of water is opened in only one of a, 102b, and 102c and the flow of the remaining water is cut off, water flowing into the addition cylinder 100 from the inflow port 101 accumulates in the addition cylinder 100. When the water reaches the outlet 102 where the flow of the water is opened, the water flows out from the outlet 102. Therefore, when the flow of the water at the lowermost outlet 102a is released, the water and the additive 103 come into contact with each other in the region a in the drawing, and the flow of the water at the outlet 102b, which is one level above, is released. In the case of opening, the water and the additive 103 come into contact with each other in a region b in the drawing, and the water and the additive The area where the contact is made larger.

At this time, the additive 103 is dissolved in water in a region where the additive 103 is in contact with water. Since the time for interaction with water becomes longer, a large amount of water is dissolved. Therefore, by adjusting the amount of water with each throttle valve 105, the opening positions of the inlet 101 and the outlet 102 in the addition cylinder 100 are adjusted. By adjusting the area where the water and the additive 103 come into contact with each other and changing the volume of the additive 103 in contact with the water in the addition cylinder 100 without changing the amount of water flowing through the addition section 4, The addition amount of 103 can be adjusted. When the addition cylinder 100 having the plurality of inlets 101 and the outlets 102 is used as described above, the additive that comes into contact with the inside of the addition cylinder 100 by adjusting the flow rate of water at the plurality of the inlets 101 and the outlets 102. The volume of 103 can be changed, which allows the amount of the additive 103 dissolved in water to be freely controlled.

When the diameter of the flow path is reduced by further adjusting the throttle valve 105 at the outlet 102 where the flow of water is opened by the throttle valve 105,
The flow velocity of the water in the branch outflow passage 108 connected to the water outlet is increased, and the pressure required when the water passes through the outlet 102 increases. For this reason, for example, when the flow of water at the outlet 102a located at the lowest position is open, in the addition cylinder 100, the inflowing water is discharged from the outlet 102a where the flow of water is open. Reaching the outlet above the formation position of the outlet 102
To ensure the pressure of the water to pass through, and at this time, the water and the additive 103
Is in contact with Therefore, when the throttle valve 105 is not throttled, the water and the additive 10 when the throttle valve 105 is throttled are compared with the area a where the water and the additive 103 come into contact with each other.
The area a 'in contact with 3 is larger. The amount of increase in the area where the water comes into contact with the additive 103 can be continuously changed by adjusting the amount of reduction of the diameter of the flow path by the throttle valve 105. The amount of the agent 103 dissolved in water can be continuously changed.

Although not shown in the figure, each throttle valve 10
When a driving device 71 for adjusting the throttle amount of 7 is provided, the amount of the additive 103 added can be controlled by driving the driving device 71.

And other residual water in the main body piping system is discharged from the drainage pipe 44. A water quality detector 20 is arranged in the middle of the discharge pipe 37.

As the water quality detector 20, a device for measuring pH, additive concentration in water, and the like is provided. An example of the structure of the water quality detector 20 will be schematically described with reference to FIGS. In FIG. 13A, the water quality detector 20 is configured as an ion measurement sensor, and in FIG.

FIG. 14 is a diagram simply illustrating the output flow from the water quality detector 20. The electromotive force generated between the comparison electrode 51 and the working electrodes 57 and 58 generated by the water quality detector 20 is converted into a considerable voltage by being amplified at an appropriate amplification factor in the potential difference amplifier 53, and converted into a considerable voltage.

The electric power for starting the potential difference amplifier 53 is supplied from the main body side of the water treatment apparatus 1, and a drive voltage of ± 12 V is applied for starting the potential difference amplifier 53 in the illustrated example. And

Next, the flow of water when generating electrolytic water from tap water will be described. When the handle lever unit 51 connected to the tap faucet 42 is switched so that water flows to the water purification device 3 side, water is introduced into the electrolytic cell 2 from the inflow passages 10 and 11 through the water purification device 3 and the addition unit 4, Although the electrolysis is performed, the application of the electrolysis voltage in the electrolytic cell 2 is started when water flow is detected by the flow rate detection sensor 38.

If the setting is such that alkaline water is obtained, an electrolytic voltage is applied so that the electrode 6 of the electrolytic cell 2 serves as an anode and the electrode 8 serves as a cathode. Acid water is generated in the chamber 7, and alkaline water is obtained on the outflow channel 12 side, and acid water is obtained on the outflow channel 13 side.
At this time, the water channel switching valve 32 is set so that the outflow channel 12 and the discharge pipe 37 communicate with each other and the outflow channel 13 and the discharge pipe 36 communicate with each other. The acidic water is discharged to the discharge pipe 36 side.

When the setting for obtaining the acidic water is made, the following two water flows are performed according to the set degree of electrolysis of the acidic water. First, in the case of weakly acidic water, an electrolytic voltage is applied so that the electrode 6 in the electrolytic cell 2 serves as a cathode and the electrode 8 serves as an anode. The alkaline water is generated on the outflow path 13 side, and the weakly acidic water is obtained on the outflow path 12 side. At this time, the water channel switching valve 32 is set in the same state as described above, the weakly acidic water is discharged to the discharge pipe 37 to be used as astringent water or the like, and the alkaline water is discharged to the discharge pipe 36 side.

In the case of strongly acidic ionic water, an electrolytic voltage is applied such that the electrode 6 in the electrolytic cell 2 serves as an anode and the electrode 8 serves as a cathode. Is generated and alkaline water is supplied to the outflow channel 12 side, and the outflow channel 1
Strongly acidic water is obtained on the three sides. At this time, the water path switching valve 32 connects the outflow path 12 and the discharge pipe 36 and simultaneously connects the outflow path 1 and the outflow path 1.
3 and the discharge pipe 37 are communicated with each other. The strongly acidic water is discharged to the discharge pipe 37 and used for sterilization and the like, and the alkaline water is discharged to the discharge pipe 36 side. As described above, when the strongly acidic water is discharged from the discharge pipe 37, the generation of the acidic water in the electrode chamber 7 using the electrode 6 as an anode is as follows.
As described above, since the inflow path 10 to the electrode chamber 7 side is narrowed down from the inflow path 11 to the electrode chamber 9 side to reduce the inflow of water, it is possible to obtain strongly acidic water in the electrode chamber 7. This is because it is easier.

In FIG. 11, the water quality detector 20 is connected to the discharge pipe 37.
And the quality of the alkaline water or acidic water flowing out of the electrolytic cell 2 can be measured. For example, as the water quality detector 20, FIG.
In the case where an apparatus configured as shown in (b) and configured to measure the concentration of ions contained in the additive 103 is provided, the adding unit 4 performs the operation based on the detection result of the water quality detector 20. The addition amount of the additive 103 can be controlled so as to be a predetermined set value.

The electrolysis conditions in the electrolyzer 2 are detected based on the detection result of the water quality detector 20, and the amount of the additive 103 in the addition section 4 is adjusted based on the electrolysis conditions so that the electrolysis conditions become a predetermined set value. Can also be adjusted. For example, in a case where the pH of the water is measured as shown in FIG. 13B, the pH of the additive 103 by the adding unit 4 is adjusted so that the pH of the electrolyzed water generated by the electrolysis becomes a predetermined set value. The amount of addition can be controlled. That is, when an electrolyte such as a calcium compound is added as the additive 103 in the addition unit 4, the electric conductivity of water can be increased to improve the electrolysis efficiency, and the amount of water can be adjusted by adjusting the addition amount. Can control the pH of alkaline water or acidic water generated by electrolysis. For this reason, when the pH of the electrolyzed water measured by the water quality detector 20 does not reach the target pH value, for example, because the electric conductivity of the raw water is low and the electrolysis voltage is difficult to conduct, the addition by the addition unit 4 is performed. By increasing the amount of the agent 103 added, the electric conductivity of raw water can be improved, and electrolyzed water having a target pH can be obtained. in this case,
The water quality detector 20 functions as a detection unit that measures electrolysis conditions in the electrolysis tank 2.

The pH detected by the water quality detector 20
The pH can be controlled to a predetermined set value by performing feedback control of the electrolytic voltage based on the detection result of.

Although not shown, the water quality detector 2
0 is disposed in the flow path of water between the adding section 4 and the electrolytic cell 2 to measure the water quality of the water before the electrolysis in the electrolytic cell 2 after the additive 103 is added. Can also. Also in this case, the water quality detector 20 shown in FIGS.
In the case where a component configured to measure the concentration of ions contained in the additive 103 is provided as shown in FIG. 3, the content of the additive 103 in water is determined based on the detection result by the water quality detector 20. The addition amount of the additive 103 by the addition unit 4 can be controlled so that the amount becomes a predetermined set value.

In the example shown in FIG. 12, in addition to the water quality detector 20a arranged at the same position as the example shown in FIG. 11, the water quality detector 20b is connected to the thermistor 39 and the constant flow valve 41.
The difference between water quality of raw water and electrolyzed water can be compared. In this case, a change in water quality is detected based on the results of water quality detection by the two water quality detectors 20a and 20b, or electrolysis conditions such as electrolysis voltage in the electrolytic cell 2 are detected based on the change in water quality. ,
The addition amount of the additive 103 by the addition unit 4 and the electrolysis voltage in the electrolysis tank 2 can be controlled based on the change in water quality and the electrolysis conditions. For example, when a compound containing calcium is added to water as the additive 103 in the adding section 4, the calcium ion content of the raw water in which the addition of the additive 103 or the electrolysis is not performed is detected by the water quality detector 20b. At the same time, by detecting the calcium ion content of the water containing the calcium compound as the additive 103 with the water quality detector 20a, the increase amount of calcium ions in the water due to the addition of the additive 103 is detected, Based on the detection result, the addition amount of the calcium compound by the addition unit 2 is controlled, and the addition amount of the additive 103 by the addition unit 4 is controlled such that the increase amount of calcium ions in water becomes a predetermined set value. Is what you can do.

FIGS. 15 and 16 show the appearance of the water treatment apparatus 1. FIG. A display operation section D is disposed on a front panel section in front of the housing 33 of the water treatment apparatus 1. Although a detailed description of the display operation unit D is omitted here, the pH changeover switches SW1, SW2, S

FIG. 18 is a part of a block circuit diagram of the water treatment apparatus 1. In FIG. 18, C is a control circuit C (control section) constituted by a microcomputer, and includes a control program and switches SW1 to SW5. , SW 10 to 12 are connected to a memory for storing input information and the like. D indicates a display operation unit and a display circuit. SW1 ...
SWs are the switches SW1 to SW5 and SW10 to SW12 described above.
The input signals from these switches are input to the control circuit C. DV is a power supply for generating an electrolytic voltage to be applied between the electrodes 6 and 8 of the electrolytic cell 4 from the electric power supplied to the water treatment apparatus 1, and r 1 and r 2 apply a voltage between the electrodes 6 and 8. This is a relay for changing the polarities of the electrodes 6 and 8 in the case where the switching is performed. The control circuit C is a switch S

It controls the value, the relays r1 and r2, or the waterway switching valve 32. Further, r0 is a relay for turning on and off the supply of the power supplied to the water treatment apparatus to the power supply unit DV. The control circuit C turns on the relay r0 when the flow detection sensor 38 detects the flow of water. By supplying power to the power supply unit DV, an electrolytic voltage is applied between the electrodes 6 and 8. When the flow detection sensor 38 no longer detects the flow of water, the relay r0 is turned off to supply power to the power supply unit DV. Is stopped, and the application of the electrolytic voltage between the electrodes 6 and 8 is stopped.

A to F shown in FIG. 18 correspond to the indications A to F in the water treatment apparatus 1 shown in FIG. 19 (the same configuration as that shown in FIG. 11).

In the case where the electrolytic voltage is feedback-controlled based on the detection result of pH by the water quality detector 20,
The control circuit C has a built-in comparison circuit for comparing the target pH value of the electrolyzed water set in SW1 to SW3 with the actually measured pH value of the electrolyzed water measured by the water quality detector 20. The feedback control of the electrolytic voltage applied to the electrodes 6 and 8 is performed so that the actually measured pH value of the electrolytic water derived from the output signal in the detection result matches the target pH value. Although the details of this feedback control will be omitted, the control is performed so that the displacement of the pH value detected by the water quality detector 20 from the target pH value is maintained within a range of ± 0.1 pH for 2 seconds. Is preferred, and the point at which such a state is reached is defined as stable electrolysis conditions.

Further, based on the detection result by the water quality detector 20, the control circuit C controls the additive 10
When controlling the addition amount of 3, when the content of the additive 103 such as calcium ions detected by the water quality detector 20 is different from the set value, the user presses the switch SW11 to switch the content of the electrolytic water. When the setting of the calcium concentration is changed or when the pH value detected by the water quality detector 20 is different from the target pH value, the control circuit C
1 is driven to feedback control the amount of the additive 103 in the adding section 4, and the amount of the additive such as the amount of calcium ions detected by the water quality detector 20 and the pH value are adjusted to predetermined target values. Value.

In the case where a component originally contained in raw water is further added, for example, when calcium ions are added to water by adding a calcium compound as the additive 103, the additive 103 is added. In addition to the case where the content of the additive 103 in the water is set later, the increase amount of the component of the additive 103 in the water due to the addition of the additive 103 may be set.

In, by comparing the detection results from the water quality detectors 20a and 20b, it is also possible to detect the increase amount of the additive 103 in the water when the additive 103 is added.

As described above, under the control of the control circuit C, for example, when the user manually presses the switch SW11 for selecting the calcium increase mode, or when the water quality detector 20 does not reach the target set value for the electrolyzed water. in the case of,
That is, for example, when the water quality of “difficult to electrolyze = electricity is hard to flow” is used as raw water, or when the target calcium concentration is not reached, the addition amount of the additive 103 in the addition unit 4 is automatically switched. The desired calcium concentration or pH value can be reached.

[0140] Even though the addition amount of the additive 103 in the addition unit 4 is controlled as described above, the amount of the additive 103 added to the addition unit 4 is less than the required amount. When the water quality such as the additive concentration or the pH measured by the water quality detector 20 does not reach the target set value, it is preferable to provide a notification unit that operates under the control of the control circuit C. In this case, It is possible to notify the user of the shortage of the additive 103 to prompt the user to replenish the additive 103 in the adding section 4. As this notifying means, means for notifying by sound such as a buzzer can be used. Further, a lamp or the like that gives notification by lighting may be provided in the display operation unit D or the like.

Among the above compounds, inorganic compounds, for example, calcium sulfate, have a relatively high calcium content of 23.3% as compared with organic compounds, and are relatively high in minerals such as calcium. The amount of the additive 103, which is a compound when a compound is added, can be reduced. Further, since it is an inorganic material, even if there is a long unused period, its quality can be maintained for a long time.

Additives include so-called vitamins and food-containing components such as cellulose-based dietary fiber, for example, organic compounds such as ascorbic acid, tocophenol, carotene, alginic acid, celluloses, lignins and pectins.
