DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tap water (including a faucet, a mixing faucet and a spout) for a kitchen, a washroom, a bathtub, and the like, and tap water (including hot water) discharged from the faucet. The present invention relates to a chlorine remover for neutralizing residual chlorine contained in tap water by mixing a chlorine neutralizer with the chlorine neutralizer.

[0002]

2. Description of the Related Art Tap water is required to be mixed with chlorine in order to sterilize and disinfect various bacteria. According to the Japanese water supply law, tap water discharged from a hydrant should not contain more than 0.1 ppm of residual chlorine. It is not required. Recently, water quality in water sources such as rivers and lakes has tended to deteriorate, and O-157 Escherichia coli and the like have been generated, so that a large amount of chlorine has been added to sterilization of raw water. Therefore, the tap water from the hydrant contains a considerable amount of residual chlorine. However, it is said that tap water containing a large amount of residual chlorine (mainly free residual chlorine such as HOCl hypochlorite) has a chlorine odor or is not good to drink, and is also said to reduce the taste of cooking. ing. In addition, residual chlorine has a bad effect on human skin and hair,
Hand washing or cooking with tap water with high residual chlorine concentration may cause roughening of fingers, and bathing may cause aging of the skin, bleaching of hair, dryness, and hair loss. Therefore, there is an increasing demand for removing residual chlorine from drinking water, face washing water, cooking water, bath water, shower water, and the like.

[0003] Under such circumstances, a water purifier mounted type water purifier has recently been marketed. This type of water purifier has a structure in which activated carbon, hollow fiber membrane, non-woven fabric, porous ceramic, etc. are stored in the water purifier body, and tap water is passed through these filter media to remove residual substances contained in the tap water. I have. Such a water purifier is originally intended to filter turbid components contained in tap water, rust in water pipes, and various odor components contained in tap water with the above-mentioned filter media, and additionally contains the filter media to contain the odor components in the tap water. It functions to physically adsorb and remove residual chlorine. However, some of the conventional water purifiers have a function of removing residual chlorine contained in tap water is insufficient even though the purifier has a chlorine removing function.

[0004] Under such circumstances, the present inventor has been researching and developing a chlorine remover to be attached to a water faucet, and has filed an example as Japanese Patent Application No. 11-359600.
This type of chlorine remover is attached to a water faucet, and is connected to a container having a sealed structure filled with an aqueous solution of a chlorine neutralizing agent such as L-ascorbic acid (vitamin C), and is connected to the container. A pipe for guiding the aqueous solution of the chlorine neutralizing agent, and formed at the end of the pipe, and when the tap water is discharged while being located in the discharge flow of the tap water discharged from the water tap, allowing the aqueous solution to flow out, And a spout from which the outflow of the aqueous solution is stopped by the action of surface tension when the discharge of tap water is stopped. According to the chlorine remover having such a configuration, when tap water is not supplied from the water tap, the outlet at the end of the pipe faces the air. At this time, surface tension is generated on the surface of the aqueous solution at the outlet, and the aqueous solution is removed. To prevent the outflow. Then, when tap water is discharged from the faucet, since the spout is located in the flow of tap water flowing out of the faucet, the tap water wets the spout, and surface tension acts on the spout. Disappears. Therefore, the spout is opened and the aqueous solution inside is spouted and mixed with tap water. Therefore, since the chlorine neutralizer is mixed with the tap water, the residual chlorine contained in the tap water can be neutralized. According to such a structure, no special valve structure is required, and the tap water supply and stop due to the opening and closing of the faucet are simply performed by simply placing the spout in the flow of water flowing out of the faucet. Therefore, the chlorine neutralizer can be automatically injected and stopped in accordance with the above conditions, so that there is an advantage that the handling is simple and unnecessary leakage of the chlorine neutralizer can be prevented.

[0005]

By the way, in the above-described chlorine remover, vitamin C discharged from the chlorine remover according to the flow rate of tap water discharged from the water tap.
It is desired that the amount of the aqueous solution to be discharged is controlled.
However, in the case of one spout, the tap water enters from the spout and the aqueous solution flows out at the same time. That is, since one spout serves both as the inlet of the tap water and the outlet of the aqueous solution, the outflow of the aqueous solution is performed. Turned out to be unstable. The present invention has been made based on such circumstances, and an object of the present invention is to provide a water tap mounting type capable of controlling the amount of the chlorine neutralizer aqueous solution to be discharged in accordance with the flow rate of tap water with high accuracy. It is intended to provide a chlorine remover.

[0006]

In order to achieve the above object, the invention of claim 1 comprises a container having a hermetically sealed structure attached to a tap water tap and filled with an aqueous solution of a chlorine neutralizing agent. A part is communicated with the inside of the container, and a leading end part is located in a discharge flow of tap water discharged from the hydrant, and an opening is formed at a leading end of the introducing passage, and is discharged from the hydrant. Introducing a part of this tap water into the introduction passage when the supplied tap water comes into contact, and an introduction port for stopping the outflow of tap water in the introduction passage when the discharge of the tap water is stopped, A supply passage whose base end is communicated with the inside of the container, and a distal end of which is located in a discharge flow of tap water discharged from the water tap, and which is opened at a distal end of the supply passage, wherein the water tap is provided. When the tap water discharged from A water tap-installed chlorine remover, which comprises: a spout for discharging the solution toward external tap water, and a spout for stopping the outflow of the aqueous solution in the supply passage when the discharge of the tap water is stopped. I will provide a.

According to the above configuration, when tap water is not discharged from the water tap, the inlet and the outlet are both exposed to air, and at this time, the liquid in the inlet and the outlet is filled with the inlet and the outlet. Even if it tries to get out of the container, the pressure inside these passages and the container tends to become negative pressure, which causes outflow resistance, and surface tension is generated on the surface of the liquid at the inlet and outlet, preventing leakage of the liquid. Therefore, the outflow of water or the aqueous solution is stopped. In other words, in this case, the closed state is the same as when the inlet and the outlet are closed. On the other hand, when tap water is discharged from the faucet, since the inlet and the outlet are both located in the flow of the tap water, the tap water wets the inlet and the outlet. Therefore, the surface tension does not work at the inlet and the spout, so that the inlet and the spout are opened. At this time, tap water intrudes from the introduction port, enters the container via the introduction passage, and the aqueous solution of the chlorine neutralizing agent in the container is discharged from the spout through the supply passage by the amount of the penetration. The discharged aqueous solution of the chlorine neutralizer mixes with the tap water, and thus neutralizes residual chlorine contained in the tap water. Therefore, according to such a chlorine remover, a special valve structure is not required, and simply placing the inlet and the outlet in the flow flowing out of the faucet can supply and stop tap water. Accordingly, the chlorine neutralizer can be automatically discharged and stopped, and unnecessary leakage of the chlorine neutralizer can be prevented.

[0008] When the discharge amount of tap water flowing out of the water tap changes, the amount of tap water entering through the inlet also changes, and thus the amount of water flowing into the container changes. Therefore, the amount of the aqueous solution flowing out of the spout also changes. From this, the amount of the chlorine neutralizer mixed can be controlled according to the flow rate of the tap water used. In this case, by independently configuring the introduction passage and the supply passage,
The entering tap water and the aqueous solution supplied from the container are not mixed in the middle of the flow, and the aqueous solution is not diluted with the tap water. Therefore, a change in the concentration of the aqueous solution to be poured can be suppressed.

In a preferred embodiment of the present invention, the aqueous solution of the chlorine neutralizing agent has a specific gravity greater than that of water, and both the introduction passage and the supply passage extend below the sealed container. If the specific gravity of the chlorine neutralizer is greater than water, the light water that has entered the introduction passage rises and enters the sealed container, and instead a heavy aqueous solution descends from the sealed container through the supply passage.
The inflow of water and the outflow of aqueous solution will be switched smoothly. The chlorine neutralizer may be filled in a container in the form of an aqueous solution.However, the powder is stored in a sealed container in the form of powder or granules, and water is poured into the container to dissolve the chlorine neutralizer. It is preferable to create an aqueous solution by using In the latter case, the chlorine neutralizer powder or granules are stored in excess in the container, and are stored in such a way that the water that was first filled into the container does not completely dissolve, leaving undissolved chlorine neutralizer. In this way, the undissolved chlorine neutralizer is sequentially dissolved by the tap water automatically replenished through the introduction passage during use. In this manner, the chlorine removal effect of tap water can be continued for a long time.

In another preferred embodiment, the inlet is upwardly opened so as to receive falling tap water, and the spout is open in a direction other than upward. If the inlet is opened upward, the dynamic pressure of tap water falling from the hydrant will be applied, so the amount of water corresponding to the flow rate of this tap water will enter the inlet passage, and the same amount of aqueous solution will be poured out. Will do. In another preferred embodiment, the introduction passage and the supply passage are formed by partitioning a single pipe (tube) with a partition wall. This not only reduces the number of parts, but also simplifies the surroundings of the water tap and does not hinder the washing operation or the like. In the present invention, calcium sulfite, sodium sulfite and the like can be used as the chlorine neutralizer, but ascorbic acids such as L-ascorbic acid (vitamin C) and sodium ascorbate are preferred. Ascorbic acids have advantages such as being easily soluble in water, having a high reaction rate with residual chlorine, and having high safety.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention in which a chlorine remover is attached to a faucet of a kitchen or the like will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which a chlorine remover is attached to a faucet pipe of a water faucet, FIG. 2 is a plan view thereof, FIG. 3 is an exploded perspective view of an attachment portion and a sealed container, and FIG. FIG. 5 and FIG. 5 are sectional views of the sealed container. In the figure, A is a well-known faucet faucet pipe installed in a kitchen or the like. The faucet pipe A has a discharge port B opened downward at the tip, and when a cock (not shown) is opened, the discharge port B is opened. From which tap water is discharged. A chlorine remover 1 of the present invention is detachably attached to the faucet pipe A.

The chlorine remover 1 of the present embodiment includes a mounting portion 10 and a sealed container 20. The attachment part 10 is for attaching the sealed container 20 to the faucet pipe A, and is detachably attached to the faucet pipe A. The mounting portion 10 of the present embodiment has clamp pieces 11a and 11b that sandwich the faucet pipe A in the vertical direction.
1a and 11b are connected to each other via a fulcrum 12 so that they can be opened and closed. These clamp pieces 11a, 11b
2 are urged in a direction to close each other by a leaf spring 13 attached to the vicinity. Therefore, these clamp pieces 1
1a and 11b can sandwich the faucet pipe A up and down, and can also sandwich the faucet pipe A having a different diameter or a sectional shape due to the elastic force of the leaf spring 13. The other clamp piece 11b is provided with a cushion member 14 which also serves as a non-slip member. A crank lever 15 is attached to the back of one clamp piece 11a. This crank lever 15
The support shafts 16a and 16b are protruded at both ends in the direction opposite to each other, and one support shaft 16a is rotatably fitted to the one clamp piece 11a. For this reason, the crank lever 15 is rotatable in the direction of the arrow X in FIG. 3 around the support shaft 15a as a rotation fulcrum. A cursor 17 is rotatably attached to the other support shaft 16b. The cursor 17 is located on the crank lever 1
5 is rotatable in the direction of arrow X about the one support shaft 16a, so that it can move on a circle having a radius equal to the distance between the support points of the crank lever 15 around the support shaft 16a. Has become. Since the cursor 17 is rotatable about the other support shaft 16b, the cursor 17 can be rotated in the direction of the arrow Y in FIG. A dovetail-shaped guide rail 18 is formed on the cursor 17.
, The sealed container 20 is detachably attached and slidably mounted in the direction of arrow Z in FIG.

The sealed container 20 is made of, for example, a synthetic resin whose upper half is transparent or translucent, and has a slide rail 19 that is slidably fitted to the guide rail 18 on the back surface. Therefore, the sealed container 20 is slidably attached to the cursor 17 in the arrow Z direction. The inside of the sealed container 20 is filled with L-ascorbic acid (vitamin C) as a chlorine neutralizer. In this case, the sealed container 20 is filled with vitamin C in the form of powder or granules (in this example, powder 21 is used), and the vitamin C powder 21 is added to the water by pouring the water into the container 20. Melts to create a saturated aqueous solution of vitamin C. Vitamin C powder 2
No. 1 has the property of being soluble in water three to four times its weight, and when the container 20 is filled with vitamin C powder completely, when the water is fully filled into the container 20, almost 1/3 to 1 / 4
Is dissolved in water, and the rest is in an undissolved state and remains as an excess. When the chlorine remover of this example is sold as a commercial product, the container 20 is emptied in advance and the vitamin C is stored in the container 20 in the order described below before the purchased user uses it.
And then tap water is injected, thereby creating an aqueous solution of vitamin C in the container 20. When the chlorine remover is sold as a product, the container 20 is filled with the vitamin C powder 21 in advance, and tap water is poured into the container 20 before the purchased user uses it. As a result, vitamin C
May be produced.

The above-mentioned vitamin C powder 21 is loaded from a loading port 22 formed in the upper wall of the container 20. The loading port 22 is closed in a gas-liquid tight manner by a screw-type closing cap 23. I have. A water inlet 24 is opened at the center of the closing cap 23.
Is opened and closed by another push cap 25. The push-in cap 25 is elastically deformed against the water inlet 24 to elastically deform, thereby sealing the water inlet 24 so that it can be opened and closed. The push-in cap 25 can open the water inlet 24 by pulling it up with a finger, and closes the water inlet 24 gas-liquid tightly by elastic deformation when pushed into the water inlet 24 with a finger. In addition, a water-permeable filter 26 is attached inside the water inlet 24 so that the vitamin C powder 21 does not fly out when water is injected.

At one corner of the sealed container 20, a filter 27 that allows water to pass through is attached, and is partitioned so that the vitamin C powder 21 filled from the loading port 22 does not enter the pipe side described later. A pipe 30 is inserted from one bottom of the container 20 into one corner defined by the filter 27. The pipe 30 is made of a metal or a synthetic resin, and has a shape that is bent in a C-shape in the middle. The upper end of the pipe 30 is inserted into the container 20 from the bottom of the sealed container 20 and is opened into the container 20. The lower end of the pipe 30 is closed. Pipe 3
The inside of 0 is divided up and down by a partition wall 31,
The upper part of this section is an introduction passage 32 for introducing tap water from the outside, and the lower part is a supply passage 33 through which the aqueous solution of vitamin in the container 20 flows down. At the tip of the pipe 30, an introduction port 34 that is located on the upper surface and guides tap water from the outside is opened upward, and the introduction port 34 is connected to the introduction passage 32. An outlet 35 for supplying an aqueous solution of vitamin C is opened downward on the lower surface of the tip of the pipe 30.
Reference numeral 5 communicates with the supply passage 33. The pipe 30
Of the faucet pipe A is positioned directly below the discharge port B by adjusting the position thereof by means described later, and the introduction port 34 and the spout 35 are dropped from the discharge port B. It is located in the bundle (flux) C of the flow of tap water, and is installed so as to be wet with the discharged water. The size of the opening of the inlet 34 and the outlet 35 is determined by the size of the inlet 3
4 and the spout 35 are exposed to the air, so that the internal tap water and the vitamin C aqueous solution do not leak out of the inlet 34 and the spout 35 due to the surface tension of the aqueous solution generated at the inlet 34 and the spout 35. The size is set to such a size, for example, each has a diameter of 1 mm or less.

Such a pipe 30 is provided in the sealed container 2.
The holding cap 37 is inserted into the container 20 through an insertion opening 36 formed in the bottom surface of the container 20 and screwed into the container 20.
And an O-ring 38 in a gas-liquid tight manner with respect to the container 20. In this case, the pipe 30 is indicated by an arrow D in FIG.
As shown by, the head can be swung about the center line of the insertion opening 36.

The operation of the chlorine remover 1 configured as described above will be described. Until the chlorine remover 1 is sold, the inside of the sealed container 20 is empty, and the user who purchases the chlorine remover 1 attaches the chlorine remover 1 to the faucet pipe A of the water tap by himself. Attach. In mounting, the mounting portion 10 and the sealed container 20 are separated, and the mounting portion 10 is mounted on the faucet pipe A. In this case, the faucet pipe A is sandwiched between the clamp pieces 11a and 11b of the mounting portion 10.
The clamp pieces 11a and 11b open and close with respect to the fulcrum 12, and receive a force in the closing direction by the urging force of the leaf spring 13, so that the clamp pieces 11a and 11b hold the faucet pipe A.

On the other hand, the separated sealed container 20 is filled with vitamin C powder 21 and tap water. In this case, first, the screw-on closing cap 23 attached to the upper wall of the sealed container 20 is removed, and the loading port 22 is opened. This loading port 2
2 to Vitamin C powder 21 are filled. The vitamin C powder 21 is filled in a region defined by the filter 27 in the sealed container 20. When a predetermined amount of the vitamin C powder 21 is filled, the loading port 22 is covered with the closing cap 23 and screwed into the loading cap 22 so as to keep gas-liquid tightness. Next, the pushing cap 25 attached to the closing cap 23 is removed, and the water inlet 24 is opened. Tap water is injected from the water inlet 24 to fill the sealed container 20 with tap water. At this time, care is taken to completely remove air so that air and air bubbles do not remain in the sealed container 20 and the pipe 30. When water is injected from the water inlet 24, the filter 26 is mounted inside the water inlet 24, so that the vitamin C powder 21 inside does not fly out. When the water is filled in the container 20 as described above,
The pushing cap 25 is pushed into the water inlet 24, and the water inlet 24 is closed in a gas-liquid tight manner.

When tap water is filled in the sealed container 20 in this way, a part of the vitamin C powder is dissolved by the tap water, and a saturated aqueous solution of vitamin C is formed in the container 20. The saturated aqueous solution also fills the pipe 30. In addition, the powder 21 of vitamin C is 3 to 4 of its weight.
It has the property of being twice as soluble in water, and when the container 20 is filled with the vitamin C powder 21 completely, when the water is fully filled into the container 20, almost 1/3 to 1/4 of the vitamin C
The powder dissolves in water and the remainder remains as undissolved excess. Further, the aqueous solution of vitamin C is heavier than the specific gravity of water, and an aqueous solution having a high concentration has a property of sinking.

When the filling of vitamin C and the injection of water as described above are completed, the sealed container 20 is attached to the attachment portion 10. This attachment is performed by inserting the slide rail 19 formed on the back surface of the sealed container 20 into the guide rail 18 of the cursor 17. Next, the sealed container 20 is adjusted so as to be substantially horizontal, and the tip of the pipe 30 is adjusted so as to be located immediately below the discharge port B of the faucet pipe A. In making these adjustments, a crank lever 15 is attached to the back of one clamp piece 11a so as to be rotatable in the direction of arrow X, and a cursor 17 is attached to the tip of this crank lever 15 so as to be rotatable in the direction of arrow Y. Therefore, the horizontality of the sealed container 20 and the position of the pipe 30 can be adjusted by rotating the crank lever 15 and the cursor 17 respectively. In addition, the sealed container 20 has a slide rail 19 formed on the back surface,
Since it is slidable along the arrow Z direction with respect to the guide rail 18 formed on the cursor 17, the direction of the sealed container 20 and the pipe 30 can be changed by this position adjustment. Furthermore, since the pipe 30 can swing around the center line of the insertion port 36,
The position of the tip of the pipe 30 can also be adjusted by this adjustment. By such an adjusting operation, the position is adjusted so that the tip of the pipe 30 is located immediately below the discharge port B of the faucet pipe A. Thus, the preparation for using the chlorine remover 1 is completed.

Next, a case where such a chlorine remover 1 is used will be described. When the cock (not shown) of the water tap is closed, tap water is not discharged from the discharge port B of the faucet pipe A, and no water is applied to the tip of the pipe 30. Therefore, the inlet 34 and the outlet 35 are exposed to air. At this time, even if the aqueous solution of vitamin C in the container 20 attempts to flow out of the inlet 34 and the outlet 35 through the pipe 30, a negative pressure is generated in the container 20 and the pipe 30, which causes resistance of the outflow. Leaks are prevented. In addition, the surface tension of the aqueous solution is generated at the openings of the inlet 34 and the spout 35, so that the aqueous solution does not flow out. That is, in this case, it is the same as the case where the inlet 34 and the spout 35 are closed. When the cock of the water tap is opened, tap water is discharged from the discharge port B of the faucet pipe A. Since the tip of the pipe 30 is inserted so as to be located in the flow C of the tap water discharged from the discharge port B, the inlet 34 and the spout 35 become wet with falling water.
Therefore, the surface tension generated at the inlet 34 and the spout 35 is released. And since the inlet 34 is formed in the upper surface of the pipe 30, it will receive the pressure of the falling tap water from the front, so that the tap water flows from the inlet 34 as shown by the broken line arrow in FIG. It enters the pipe 30. This tap water has a lower specific gravity than the vitamin C aqueous solution, so that the introduction passage 3 partitioned by the partition wall 31 is used.
2 and rises in the introduction passage 32 and enters the container 20 from the upper end. When water enters the sealed container 20, the aqueous solution of vitamin C in the container 20 flows down through the supply passage 33 as shown by the solid line arrow in FIG. When the discharge amount of the tap water flowing out of the faucet pipe A changes, the amount of the tap water entering through the inlet 34 also changes, and thus the amount of the water flowing into the container 20 changes. Also changes. From this, the amount of the chlorine neutralizer mixed can be controlled according to the flow rate of the tap water used. In this case, since the introduction passage 32 and the supply passage 33 are configured independently, the entering tap water and the container 2
The aqueous solution supplied from 0 does not mix on the way, and the aqueous solution is not diluted with tap water. Therefore, a change in the concentration of the aqueous solution to be poured can be suppressed. For this reason, the aqueous vitamin C solution is mixed with the tap water discharged from the discharge port B, and the residual chlorine contained in the tap water chemically reacts with the vitamin C to change to a harmless chlorine compound. Therefore, the tap water is neutralized with chlorine, and even if it is washed with hands, face, and washing with this water, it is possible to prevent rough skin such as stretching and drying of the skin.

As described above, the tap water introduced from the inlet 34 rises in the introduction passage 32, and the introduced aqueous vitamin solution flows down the supply passage 33 and is discharged from the outlet 35. Inflow and outflow occur simultaneously. This is because the tap water has a specific gravity smaller than that of the aqueous vitamin solution, so that the tap water rises through the introduction passage 34, and at the same time, the heavy vitamin C aqueous solution flows down along the supply passage 33. As a result, the aqueous vitamin solution flows out of the outlet 35 according to the amount of tap water introduced from the inlet 34, and the amount of tap water flowing from the inlet 34 is the amount of tap water discharged from the faucet pipe A. Therefore, an aqueous solution of vitamin C corresponding to the amount of discharged water can be supplied. Since tap water is replenished in the container 20 instead of the aqueous vitamin C solution that has flowed down, the newly-entered tap water dissolves the undissolved vitamin C powder 21 and constantly produces a saturated aqueous solution. Therefore,
Until the undissolved vitamin C powder 21 disappears, a saturated aqueous solution can be prepared and this aqueous solution can be mixed into tap water. As can be seen from such an operation, the pipe 30 is connected to the container 2.
The reason for extending downward from the lower part of 0 is to cause the flow using the specific gravity of the vitamin C aqueous solution and to smoothly supply the aqueous solution in the container 20 to the spout 35.

In the case of the chlorine remover 1 as described above, since the inlet 34 and the outlet 35 are opened and closed by the surface tension of the aqueous solution, no special valve structure is required and the structure is simple. Further, according to such a chlorine remover 1, since the vitamin C aqueous solution is mixed with the tap water discharged from the faucet pipe A, a water purifier of a type that captures residual chlorine with a conventional filter medium. As described above, pressure loss does not occur in the discharge water, and the flow rate per unit time is a flow rate according to the degree of opening of the cock, so that a large amount of tap water neutralized with residual chlorine can be used per unit time. In addition, introduction passage 3
2 and the supply passage 33 divide the inside of one pipe 30 into the partition wall 31.
, The structure is simple and there is no need to worry about bulkiness. Further, the container 20 has a structure in which the container 20 is attached to the faucet pipe A of the mixing tap via the attachment portion 10,
This installation is performed with the faucet pipe A using the clamp pieces 11a and 11b.
, The structure is simple enough to pinch it, so that it is easy to attach and even a woman can handle it easily.

In the above embodiment, the introduction passage 32 and the supply passage 33 are formed by dividing the inside of one pipe 30 by the partition wall 31, but the introduction passage 32 and the supply passage 33 are constituted by separate pipes. Is also good. In addition, although the inlet 34 and the spout 35 are formed one by one, each of these or any one of them may be formed in plural. However, in this case, when tap water is not discharged from the faucet pipe A, it is necessary to consider the size and number of the mouths so that the vitamin C aqueous solution does not leak or drip. Further, in the above embodiment, the container 20 is attached to the faucet pipe A via the clamp pieces 11a and 11b formed on the attachment portion 10. However, the structure for attaching the container 20 to a water tap, a faucet, a spout, or the like is described in the above embodiment. Not limited to the example, various means are possible. In short, the introduction port 34 and the spout 35 are connected to the discharge port B.
What is necessary is just to mount so that it may be located in the flux which falls from. In this case, since a chlorine remover of this type is often handled by a woman at home, it is desirable that the chlorine remover has a structure that can be easily attached by a woman.

[0025]

As described above, according to the present invention, when the discharge amount of tap water flowing out of the water tap changes, the amount of tap water entering through the inlet changes, thereby changing the amount of water flowing into the container. Therefore, the amount of the aqueous solution flowing out of the spout also changes. Therefore, the amount of the chlorine neutralizer mixed can be controlled according to the flow rate of the tap water used. In this case, since the introduction passage and the supply passage are configured independently of each other, the entering tap water and the aqueous solution supplied from the container do not mix on the way, and the aqueous solution is not diluted with the tap water. Therefore, it is possible to suppress a change in the concentration of the aqueous solution to be discharged, and to effectively neutralize the residual chlorine by discharging the optimal aqueous solution in accordance with the discharge flow rate of the tap water.
