DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is directed to hot water or water poured into a bathtub, basin, wash basin, or other fish breeding aquarium.・ Supplier for underwater-type contaminant solution that purifies and improves water quality by supplying an appropriate amount of contaminants such as alkaline agents, skin lotion, bath agents, moisturizers, etc. About.

[0002]

2. Description of the Related Art For example, tap water is required to be mixed with chlorine in order to sterilize and disinfect various bacteria. However, residual chlorine (particularly, free residual chlorine such as HOCl hypochlorite) contained in tap water is human. It is said that taking a bath containing such a large amount of residual chlorine is not good for health because it has a bad effect on skin and hair. For this reason, Japanese Patent Laid-Open Publication No.
No. 90 proposes a simple water purifier to be used floating in a bathtub. In this device, a container floating in water (hot water) stretched in a bath tub is provided with a large number of holes penetrating inside and outside, and the container is filled with purifying particles for purifying water. In such a water purifier, when it floats in a bathtub, water flows in and out through a number of small holes, and this water purifies the water in the bathtub by touching the purification powder. In the case of the above publication, bioceramics are described as a chlorine removing (neutralizing) agent, and it is described that when water comes into contact with the bioceramics, free residual chlorine mixed in the water is removed. However, this method has a problem that it takes a long time to neutralize chlorine in the water in the entire bathtub, since only water entering and exiting the water purifier contacts the bioceramics.

On the other hand, water-soluble powders or granules, or solution-type chlorine neutralizers are considered. If a water-soluble powder, granule or solution-type chlorine neutralizer is used, when water comes in contact with it, the chlorine neutralizer dissolves in the water, diffuses, and spreads throughout the bathtub. Can be summed up. As such a chlorine neutralizer, L-ascorbic acid (vitamin C), sodium L-ascorbate, calcium sulfite, sodium sulfite and the like are known. Above all, L-ascorbic acid and sodium L-ascorbate are widely known as food additives and therefore have high safety, and are suitable for use because they have a cosmetic effect when used in lotions and the like. Therefore, when L-ascorbic acid and / or sodium L-ascorbate is used in the water purifier described in the above publication, a prompt and smooth chlorine neutralization effect can be expected.

[0004] When L-ascorbic acid or sodium L-ascorbate is used as a chlorine neutralizing agent when housed in a water purifier that floats in a bath, there are the following problems. That is, L-ascorbic acid (hereinafter, simply referred to as ascorbic acid) is excellent in hygroscopicity, deliquescent,
Dissolves instantly on contact with water. However, the saturated solubility of ascorbic acid is said to be about 25%. Therefore, when ascorbic acid powder or granules are wrapped in a net-like sheet and stored in the water purifier described in the above publication, ascorbic acid is instantly dissolved by the water flowing from the small holes of the container, and the water entering the container is Dissolves until solubility reaches 25%. Even if ascorbic acid powder remains, the remaining ascorbic acid powder or granules are sequentially dissolved by the replacement of water. Therefore, the ascorbic acid packed in the container is completely dissolved by one use,
The second and subsequent uses will not be possible.

On the other hand, ascorbic acid (chemical formula C ₆ H ₈ O)
₆ , molecular weight 176) is said to cause the following chemical reaction with hypochlorous acid (chemical formula HOCl, molecular weight 52.45), which is a main component of free residual chlorine.

[0006]

Embedded image C ₆ H ₈ O ₆ + HOCl → C ₆ H ₆ O ₆ +
HCl + H ₂ O

That is, 1 mol of ascorbic acid reacts with 1 mol of hypochlorous acid to form dehydroascorbic acid (C ₆
One mole of H ₆ O ₆ ), one mole of chloric acid (HCl) and one mole of water (H ₂ O) are produced. That is, 176 g of ascorbic acid causes a chemical reaction with 52.45 g of hypochlorous acid,
In other words, 3.35 g of ascorbic acid is required to convert 1 g of hypochlorous acid to harmless chloric acid. Therefore, for example, assuming that the amount of water in the bathtub is 200 liters and the concentration of hypochlorous acid, which is the main component of the residual chlorine, is 1.0 ppm, it is necessary to use ascorbin to completely neutralize the residual chlorine completely. 0.67 g of acid is required. Conversely, in order to neutralize chlorine for one bath, only 0.67 g of ascorbic acid may be added. If this is made into a 25% saturated aqueous solution, about 2 ml of the aqueous solution of ascorbic acid may be used, and if the ascorbic acid is supplied any more, useless consumption of ascorbic acid increases.

[0008]

However, supplying as little as 0.67 g of ascorbic acid and only about 2 ml of an aqueous solution in a single use requires a very small amount of ascorbic acid to control the release. There is a problem that is difficult. It is desirable that this type of water purifier can be used many times. For this purpose, a large amount of ascorbic acid should be filled in a container in advance, and the amount corresponding to the amount used for each use should be gradually released after each use. Is desired. Therefore, it is desirable to supply a large amount of ascorbic acid to the dispenser once, but as described above, there is a problem that it is difficult to supply a small amount of ascorbic acid one by one. In addition, such a water purifier is lifted from the bathtub when not in use, but ascorbic acid leaks at this time, ascorbic acid is wasted, and ascorbic acid must be replenished frequently, Problems such as an aqueous solution of ascorbic acid oxidizing metal objects occur.

The present invention has been made in view of such circumstances, and it is an object of the present invention to mix an appropriate amount of water in a bathtub, a basin, a washbasin, or various water tanks. It is an object of the present invention to provide a dispenser for a water-injected contaminant solution which can discharge the contaminant solution and prevent leakage of the contaminant solution when not in use.

[0010]

In order to achieve the above object, an invention according to a first aspect of the present invention is a feeder main body which can be put into water and can be pulled up from water, and maintains a vertical posture when put into water. And a mixing agent storage chamber provided in the supply unit main body and configured to store the mixing agent and water to form an aqueous solution of the mixing agent, and a mixing agent formed in the mixing agent storage chamber, communicating with the mixing agent storage chamber. An aqueous solution measuring chamber for storing a predetermined amount of an aqueous solution of
A dispenser for a water-containing contaminant solution, which is provided below a water surface when the water is poured into water and has a discharge hole for discharging the contaminant aqueous solution of the aqueous solution measuring chamber into water.

Here, the contaminant is a chlorine neutralizer, an aromatic agent,
It contains tap water purifiers and modifiers such as oxidizing agents, alkaline agents, skin lotions, bath agents, moisturizers, etc., and is soluble in water. The form of the contaminant to be stored in the contaminant storage chamber may be a solid in the form of powder, granules or pellets in advance, or may be a concentrated liquid,
It may be soluble in water or diluted with water. And when the contaminant is solid, the amount of the contaminant to be stored in the contaminant storage chamber is not dissolved by only one injection of water, but a part is dissolved and the remaining remains in a solid form, It is preferable that the amount is such that it dissolves sequentially as the number of uses increases. In addition, the case of being put into water in the present invention includes all cases such as floating on the water surface, sinking to the bottom of the water, or floating between the water surface and the bottom.

According to the first aspect of the present invention, when the supply device of the present invention is poured into hot water or water stretched over a bathtub, a basin, a washbasin, or another water tank, the discharge hole connected to the aqueous solution measuring chamber is submerged in the water. By immersion, the aqueous solution in the measuring chamber and the external water come into contact with each other. For this reason, the aqueous solution in the measuring chamber and the external water are exchanged with each other due to the effect of diffusion or the like. Therefore, the aqueous solution stored in the measuring chamber is released to the outside and mixes with the outside water. This discharge amount corresponds to the amount of the aqueous solution stored in the measuring chamber. Therefore, if the volume of the aqueous solution in the measuring chamber is set to one discharge, the necessary amount of the contaminant is supplied each time. Can be. In the aqueous solution measuring chamber, the concentration of the aqueous solution decreases due to the entry of water from the outside, but since the aqueous solution measuring chamber communicates with the mixed agent storing chamber, for example, when the aqueous solution measuring chamber is pulled up from the water, the concentrated aqueous solution in the mixed agent storing chamber is Flows into the measuring chamber due to diffusion, specific gravity difference, etc., so that the aqueous solution to be used next time can be stored in the measuring chamber. And when it is lifted from the water, the discharge hole comes to face the atmosphere. In this case, the internal aqueous solution tends to leak from the discharge hole, but since the measuring chamber and the contaminant storage chamber have a closed structure and are filled with the aqueous solution, when the aqueous solution tries to flow out of the discharge hole, the inner component is under negative pressure. Therefore, leakage of the aqueous solution is prevented by the negative pressure.

According to a second aspect of the present invention, there is provided a feeder main body which can be put into water and pulled up from the water, and maintains a vertical direction when put in water, and a vertical direction with respect to the feeder main body. A rotatable mounting, the rotating posture changes between when in water and when lifted up from the water, and the mixed agent storage chamber for storing the mixed agent and water to form an aqueous solution of the mixed agent; Provided in the medicine container,
A rotating means for rotating the mixed-agent storage chamber to a predetermined posture by buoyancy or weight when put into water; and a communicating means for communicating with the mixed-agent storage chamber and forming the mixed-agent mixed in the mixed-agent storage chamber. An aqueous solution measuring chamber for storing a predetermined amount of an aqueous solution, and a discharge hole which is located below the water surface when poured into water, is opened in tandem with the aqueous solution measuring chamber, and discharges the mixed agent aqueous solution of the mixed agent measuring chamber into water. And a feeder for a water-containing contaminant solution comprising:

In the case of the present invention, the direction of the mixing agent storage chamber changes depending on the action of the rotating means between the case where the mixture is in the air and the case where the mixture is in the water. By this rotation, the aqueous solution in the mixed agent storage chamber and the measuring chamber is agitated, and the concentration of the aqueous solution is kept uniform.
Other operations are the same as those of the first aspect.

In a preferred embodiment of the present invention, a buoyancy generating means or a weight is provided on the main body of the feeder, and the buoyancy generating means or the weight keeps a vertical posture when the apparatus is underwater. In the case of such a structure, when in the water, the main body of the supply unit maintains a vertical orientation and assumes a predetermined posture, so that the discharge hole can be always positioned below the water surface. According to another preferred embodiment of the present invention, the size of the discharge hole is such that the aqueous solution of the contaminant and the external water can be exchangeably passed when it is in water, and the surface tension of the aqueous solution of the contaminant acts when it is in the air. It is of a size to prevent leakage of the aqueous solution. According to this, even when the aqueous solution inside is about to leak out from the discharge hole, especially when in the air, as described above, the measuring chamber and the contaminant storage chamber have a closed structure and are filled with the aqueous solution. Therefore, in addition to preventing the leakage of the aqueous solution, the aqueous solution tends to stop in the discharge hole due to the surface tension of the aqueous solution, thereby preventing the leakage.

In the present invention, when the mixed agent whose specific gravity of the aqueous solution is larger than 1 is supplied to water or hot water, the aqueous solution measuring chamber is positioned above the mixed agent storage chamber in a posture when it is in water. It is preferable that the discharge hole is opened at a predetermined position below the upper end of the aqueous solution measuring chamber. According to such a configuration, the amount of the aqueous solution stored in the measuring chamber stored in the region located above the discharge hole flows out of the discharge hole due to a difference in specific gravity. Therefore, it is possible to control the release amount of the aqueous solution with higher accuracy.

According to another aspect of the present invention, a contaminant-containing chamber is provided which contains an undissolved contaminant and water and forms an aqueous solution of the contaminant; It is preferable that an aqueous solution storage chamber for storing an aqueous solution of the agent is provided, and an aqueous solution measuring chamber is formed or communicated with the aqueous solution storage chamber. In such a configuration, it is difficult for the undissolved contaminant to enter the measuring chamber. Further, in the present invention, the contaminant is stored in the contaminant accommodating chamber for a number of times, and a part of this is dissolved in water, and once the aqueous solution is released, the undissolved contaminant is sequentially removed. It is desired to dissolve to form an aqueous solution. In this case, since the undissolved admixture remains in the admixture accommodating chamber, a water-permeable admixture that prevents the undissolved admixture from entering the release hole in the admixture accommodating chamber or the release hole. Preferably, a blocking member is provided. Thereby, it is possible to prevent the undissolved contaminant from being directly released from the release hole.

When it is desired to release the mixed agent aqueous solution from the discharge hole in a short time, the opening area of the discharge hole is increased, and the discharge hole is opened when it is put into water, and opened when it is pulled out of the water. It is preferable to provide an automatic open / close valve that opens. In this way, the aqueous solution can be released quickly, and furthermore, leakage from the aqueous solution is prevented when the aqueous solution is pulled out of the water. When the contaminant is a chlorine neutralizing agent for neutralizing residual chlorine contained in tap water, for example, L-ascorbic acid (vitamin C), sodium L-ascorbate, calcium sulfite, sodium sulfite, etc. It can be used as a water purifier for neutralizing chlorine.

In a preferred aspect of the present invention, at least the contaminant storage chamber is detachable from the supply main body, and the contaminant storage chamber is a replacement cartridge. In this case, if there is no mixed agent in the mixed agent storage chamber, the mixed agent storage chamber can be removed and replaced with a new mixed agent storage chamber (cartridge).

Furthermore, it is desirable that at least a part of the mixed agent accommodating chamber is configured so that the remaining amount of the undissolved mixed agent remaining inside from the outside can be seen. In such a case, since the remaining amount of the mixed agent can be confirmed from the outside, it is possible to determine whether or not the mixture can be used, how much can be used, or the replacement time. In this case, the state that can be seen from the outside can be transparent, colored transparent, translucent, or the like.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention applied to a simple water purifier for underwater use for a bathtub for neutralizing residual chlorine in water (hot water) stretched in the bathtub will be described with reference to the drawings. . FIG. 1 is a cross-sectional view of a water purifier floating on the surface of a bathtub, FIG. 2 is a cross-sectional view of a state where the water purifier is pulled up from a bathtub and placed on an edge of the bathtub, and FIGS. 3 and 4 are enlarged cross-sectional views of main parts, respectively. FIG. 5 is an overall view of a state in which the purifier is used floating on the bathtub 18.

In FIG. 1, reference numeral 1 denotes a water purifier main body corresponding to the supply unit main body of the present invention.
It is made of a heat-resistant synthetic resin such as BS resin or polypropylene, and in the case of this example, is formed transparent.
The water purifier main body 1 has a hemispherical outer shape, and has a mixed agent storage chamber 2 formed therein. In the case of this example, the mixed agent storage chamber 2 is partitioned into a mixed agent dissolving chamber 3 and an aqueous solution storage chamber 4. The contaminant dissolution chamber 3 is formed at a position located at the bottom of the water purifier main body 1 in a posture where the water purifier main body 1 is floated on the water surface as shown in FIG. 1 and has a large volume. The dissolution chamber 3 contains ascorbic acid (vitamin C) in the form of powder or granules 5 as a chlorine neutralizing agent corresponding to the contaminant of the present invention. The aqueous solution storage chamber 4 is located above the center of the mixed agent dissolution chamber 3 and is formed continuously with the dissolution chamber 3.

The dissolution chamber 3 and the aqueous solution storage chamber 4 communicate with each other so as to allow water to pass therethrough, and a water-permeable member, such as a nonwoven fabric or a mesh sheet 6, for preventing the passage of the contaminant is interposed therebetween. Is provided. The mesh sheet 6 prevents the ascorbic acid granules 5 in the dissolving chamber 3 from entering the aqueous solution storage chamber 4, but allows the aqueous solution of ascorbic acid to pass freely. The mesh sheet 6 is attached to an opening inside the release hole 10 described later, and the ascorbic acid granules 5
May be prevented from coming out of the discharge hole. At least one of the dissolution chamber 3 and the aqueous solution storage chamber 4, in the case of this example, both chambers are provided with air vent holes, and these air vent holes are gas-liquid tightly sealed by plugs 7 and 8. ing.

The water purifier body 1 has a discharge passage 9 formed of a vertically extending pipe located at the center. The discharge passage 9 penetrates the dissolution chamber 3 and the aqueous solution storage chamber 4, and the upper and lower ends are open.
A discharge hole 10 is formed in the aqueous solution storage chamber 4 so as to face the discharge passage 9. The discharge hole 10 connects the aqueous solution storage chamber 4 and the discharge passage 9 to each other, and thereby supplies the aqueous solution in the aqueous solution storage chamber 4 to the discharge passage 9. In this case, as shown in FIG. 3, the opening position of the discharge hole 10 is formed at a position lower than the upper end of the aqueous solution storage chamber 4 by a predetermined dimension S, and is located above the opening position of the discharge hole 10. The aqueous solution storage chamber is an aqueous solution measuring chamber 11. Since the aqueous solution measuring chamber 11 is located above the opening position of the discharge hole 10, the volume of the portion above the discharge hole 10 is such that the ascorbic acid aqueous solution is supplied once to the water filled in the bathtub 20. Is set to match. The capacity of the measuring chamber 11 is, for example, about 2 to 5 ml. In addition, this discharge hole 1
The size of 0 is set such that the aqueous solution of ascorbic acid for one use can be released within a few minutes, and when in air, the aqueous solution does not leak due to the surface tension of the aqueous solution of ascorbic acid. For example, the diameter is 5 mm or less.

A cap 12 is placed on the hemispherical water purifier main body 1 as described above. The cap 12 has a hemispherical shape, and is configured so that the whole water purifier has a spherical shape when attached to the water purifier main body 1. A float 13 as buoyancy generating means is provided inside the cap 12. The float 13 may form an air-tight air chamber in the cap 12, but in this embodiment, a floating body having a specific gravity smaller than 1 is fixed to the cap 12. In addition, the float 13 may be attached to the upper part of the water purifier main body 1.
Further, instead of the float 13, a weight may be attached to the bottom of the water purifier main body 1. In any case, when the water purifier main body 1 is put into water, the dissolving chamber 3 should be in a downward position and the measuring chamber 11 should be in an attitude in which the measuring chamber 11 is in an upward direction, as shown in FIG. An internal space 14 is formed between the water purifier main body 1 and the cap 12.
Numeral 4 communicates with the outside through a plurality of water holes 15 formed in a side surface of the water purifier main body 1, for example. When such a water purifier is dropped into water, the float 13 is floated by the buoyancy of the float 13 with a part of the upper part being exposed from the water surface as shown in FIG. , Water enters through the water passage hole 15. Float 13 above
Is set such that the water surface of the internal space 14 is at least above the position of the discharge hole 10. In this case, the upper end of the discharge passage 9 is open to the internal space 14. The upper end of the discharge passage 9 is
An opening may be provided on the upper surface of the cap 12.

Regarding the water purifier of the first embodiment having the above structure,
The operation will be described. Before use, the plug 7 of the air vent hole is opened, and the dissolution chamber 3 is filled with the ascorbic acid granules 5 from here. The filling amount of the granules 5 is determined by adding several tens or
Desirably, the amount can be used several hundred times. And
Water is injected into the dissolution chamber 3 from the air vent hole. When injecting water, when the water purifier body 1 is submerged below the water surface with the air vent hole facing upward, the air in the melting chamber 3 floats out from the air vent hole and escapes outside, and at the same time, the air is released through the air vent hole. Of water flows into the dissolution chamber 3. When no air bubbles come out of the melting chamber 3, the stopper 7 closes the air vent hole, and the gas-liquid tightness of the melting chamber 3 is maintained. Similarly, the stopper 8 is opened to evacuate the air in the aqueous solution storage chamber 4, and water is injected into the aqueous solution storage chamber 4. When the air in the aqueous solution storage chamber 4 is removed, the stopper 8 is closed to maintain the gas-liquid tightness of the aqueous solution storage chamber 4. The plugs 7 and 8 may be either one of them, and may be provided with a float-type automatic air vent valve (not shown) and the like.
The air may be automatically evacuated when water is submerged, and water may be injected instead. In short, it is sufficient that air is not left in both the dissolution chamber 3 and the aqueous solution storage chamber 4, and both chambers are filled with water, and it is important that no air remains.

When the water is poured into the entire mixture containing accommodating chamber 2 in this manner, the ascorbic acid granules 5 accommodated in the dissolving chamber 3 are dissolved. That is, ascorbic acid dissolves instantly when mixed with water because it has water absorption and deliquescent. However, since the solubility of ascorbic acid is about 25%, when the dissolution concentration reaches about 25%, it reaches a saturated state and does not dissolve any more. Therefore, the ascorbic acid contained in the dissolution chamber 3 is dissolved in water until the saturated concentration is reached, but further dissolution does not proceed, so that the remaining granules 5 remain in a granular state without being dissolved. On the other hand, the aqueous solution of ascorbic acid has a specific gravity of about 1.1 at a saturated concentration. For this reason, when a concentration difference occurs, a strong aqueous solution tends to sink down. Therefore, the water purifier after injecting the water is pulled up into the air, and as shown in FIG.
It is preferable to place it upside down, for example, on the edge of the bathtub 18 or the like. In this case, the tray 19 as shown in FIG.
Is prepared and placed on the tray 19, the spherical water purifier maintains a stable posture.

When the water purifier is turned upside down, the dissolution chamber 3
Is higher than the aqueous solution storage chamber 4, and the concentration of the ascorbic acid aqueous solution dissolved in the dissolution chamber 3 is high.
Flow into Therefore, the concentration of the aqueous solution in the aqueous solution storage chamber 4 becomes high. This concentration is close to the saturation concentration. At this time, the granules 5 remaining in the dissolution chamber 3 are blocked from passing by the mesh sheet 6, so that the aqueous solution storage chamber 4
Is prevented. On the other hand, in the aqueous solution storage chamber 4 into which the high-concentration aqueous solution has flowed, the existing water or the low-concentration aqueous solution replaces the high-concentration aqueous solution and flows into the dissolution chamber 3, whereby the granules in the dissolution chamber 3 are dispersed. Dissolve 5 until saturation solubility is reached.

By the way, when the water purifier is in the air as described above, the water in the internal space 14 and the discharge passage 9 does not flow out, so that air exists in the discharge passage 9.
For this reason, as shown in FIG.
The side becomes the air layer. In this state, the mixed agent storage chamber 2 is filled with the aqueous solution to maintain gas-liquid tightness.
When the aqueous solution tries to leak from 0, the inside of the storage chamber 2 tends to become negative pressure, and thus the leakage of the aqueous solution is prevented by the pressure difference between the inside and the outside. At the same time, surface tension of ascorbic acid is generated at the interface between the aqueous solution of ascorbic acid and air in the discharge hole 10, thereby preventing the aqueous solution from leaking from the aqueous solution storage chamber 4 to the release passage 9. That is, the size of the discharge hole 10 is set to a size suitable for preventing the aqueous solution from flowing out due to the surface tension. Thus, when the water purifier is pulled up into the air, no outflow of the aqueous solution occurs.

Next, as shown in FIG.
Pour into water stretched to 8. Then, as shown in an enlarged manner in FIG. 1, water enters into the discharge passage 9 formed in the central portion of the water purifier, and also enters the internal space 14 through the water passage hole 15 formed in the side surface of the water purifier main body 1. Water enters. However, the water purifier floats in water by the action of the float 13 provided on the cap 12. At this time, the posture floating in the water is always the posture in which the melting chamber 3 is at the bottom, that is, the vertical direction is determined as shown in FIG. The draft line of the water purifier is determined by the buoyancy of the float 13, and in this case, the position of the discharge hole 10 is always set to be lower than the water surface by a predetermined height H. When the water purifier floats on the water surface in this way, water enters the discharge passage 9, and the water in the discharge passage 9 communicates with the discharge hole 10. That is, as shown in FIG. 3, the aqueous solution of ascorbic acid in the aqueous solution storage chamber 4 comes into contact with the water in the discharge passage 9. In this state, since the specific gravity of the ascorbic acid aqueous solution is larger than water, the portion of the aqueous solution storage chamber 4 located above the discharge hole 10, that is, the aqueous solution in the measuring chamber 11 tends to descend by the action of gravity, The liquid flows out from the discharge hole 10 at the lower position of the discharge passage 11 into the discharge passage 9. At this time, the discharge passage 9 is used instead of the outflow of the aqueous solution.
The water inside flows into the measuring chamber 12. As described above, the outflow of the ascorbic acid aqueous solution and the inflow of the water occur at the same time, and the total amount of water in the mixed agent storage chamber 2 does not decrease. This is thought to be due to the diffusion effect.

As described above, the aqueous solution of ascorbic acid that has flowed into the discharge passage 9 flows downward in the discharge passage 9 because the specific gravity is still large, and the water in the bath tub 18 is discharged from the lower end opening of the discharge passage 9. Released. If this water is agitated, ascorbic acid spreads throughout the bath and reacts with the free residual chlorine contained in the water to neutralize it.

Since the aqueous solution of ascorbic acid released from the discharge hole 10 flows out due to a difference in specific gravity, an amount of the aqueous solution stored in the region located above the discharge hole 10, ie, the measuring chamber 11, flows out. When the aqueous solution in the measuring chamber 3 flows out, the concentration difference and the specific gravity difference disappear or decrease inside and outside the discharge hole 10, so that the replacement of water stops. This terminates the release of the aqueous ascorbic acid solution. From this, one use corresponds to the volume in the measuring chamber 11, and if this volume is regulated, the amount of ascorbic acid released corresponding to one use can be controlled.

When the supply of ascorbic acid is completed as described above, the water purifier is pulled up, and as shown in FIG.
May be placed on the saucer 19 placed on the edge of. At this time, it is desirable that the water purifier be placed upside down. As a result, as described above, since the dissolution chamber 3 is located above the aqueous solution storage chamber 4, the high-concentration ascorbic acid aqueous solution in the dissolution chamber 3 flows into the aqueous solution storage chamber 4, and the measuring chamber 114.
The aqueous solution inside becomes high concentration. Therefore, the next release is replenished in the measuring chamber 11. In addition, the water that flows into the dissolution chamber 3 in place of the high-concentration aqueous solution or the low-concentration aqueous solution is used as the granules 5 in the dissolution chamber 3 that have not yet been dissolved.
And dissolve until saturation solubility is reached. Therefore, 1
The granules used twice will be dissolved.

As described above, if the water purifier is turned upside down when the water purifier is underwater and when the water purifier is pulled out of the water, the contents in the mixed agent storage chamber 2 are also turned upside down. Will be stirred. For this reason, even if a high concentration aqueous solution tends to sink down due to a difference in specific gravity, it can be stirred every time it is used, so that the concentration of the aqueous solution can be made uniform and the concentration variation of the released aqueous solution can be reduced. Can be prevented. Further, the undissolved ascorbic acid granules 5 remaining in the dissolution chamber 3 have a property that they tend to sink down and accumulate on the bottom of the dissolution chamber 3 because of their large specific gravity. On the other hand, if the water purifier is turned upside down between when it is in water and when it is pulled up from the water, the undissolved granules 5 move up and down as can be seen by comparing FIGS. For this reason, the granules 5 are also agitated, so that they are prevented from accumulating in one place.

In the water purifier having the above configuration, 1
The dissolution of ascorbic acid and the release of the aqueous solution are repeated each time it is used, so that it can be used many times until the granules 5 of ascorbic acid stored in the powder storage chamber 3 are exhausted. From the above, the amount of ascorbic acid necessary and sufficient to neutralize the residual chlorine contained in the water stretched in the bathtub 18 can be supplied with high accuracy. Can be used effectively, and the water supply device can be used for a long period of time. Moreover, in such a water purifier, since the contaminant storage chamber 2 is transparent, the undissolved ascorbic acid granules 5 remaining inside from outside can be seen through. Therefore, the remaining amount of ascorbic acid can be visually recognized from the outside, and when the remaining amount is exhausted, it may be replaced.

In the first embodiment, the water purifier is turned upside down between when the water purifier is in the water and when the water purifier is pulled out of the water. The present invention may be configured as in the second embodiment shown in FIGS. That is, FIG. 6 is a cross-sectional view in a state of being lifted out of the bathtub and placed on the edge of the bathtub, FIG. 7 is a cross-sectional view of the bathtub floating on the water surface, and FIG. 8 is a cross-sectional view of a main part. In the figure, reference numeral 20 denotes a water purifier main body corresponding to the supply device main body of the present invention. The water purifier main body 20 has a spherical outer shape, and a floating body 21 constituting an upper half of a hemisphere, and a hemisphere Lower cover 2 that constitutes the lower half of the shape
2 are connected so as to be decomposable with each other. The floating body 21 and the lower cover 22 are made of a heat-resistant synthetic resin, and are formed to be transparent in this embodiment.

The upper half floating body 21 constitutes the buoyancy generating means of the present invention, and has an airtight air chamber 23 on the ceiling surface. Thereby, when the water purifier main body 20 is put into the water, the top of the floating body 21 faces upward. A plurality of water holes 24 are opened in the side wall of the floating body 21, and an air vent hole 25 is formed in the center portion through the air chamber 23. Further, inside the floating body 21, supporting walls 26, 26 which are suspended to face each other are formed. Each of these support walls 26, 26 has a bearing hole 2
7, 27 are formed. In addition, these support walls 26,
A plurality of water holes 28 are also formed in 26. The lower cover 22 protects the contents inside, and
It is detachably connected to the device by means such as screwing, bayonet, and elastic. The bottom surface of the lower cover 22 is formed as a flat surface 29 to maintain stability when the lower cover 22 is placed. Water holes 24 are also formed in the side wall and the flat surface 29 of the lower cover 22, respectively.

The cartridge 30 is detachably housed in the water purifier main body 20 having the above-described structure. Cartridge 3
0 has a substantially cylindrical shape, and has shafts 31, 31 on both end surfaces.
It has. These support shafts 31, 31 are detachably attached to bearing holes 27, 27 of the support walls 26, 26 formed on the floating body 21. When the support shafts 31, 31 are detached from the bearing holes 27, the support walls 26, 26 are elastically deformed as shown by imaginary lines in FIG. The space between them is widened and detached. When the lower cover 22 is attached to the floating body 21, the support shafts 26 of the cartridge 30 are prevented from being elastically deformed by the stoppers 32 formed on the lower cover 22, thereby preventing the cartridge 30 from falling off. I have. The support shaft 3
In a state where the cartridges 1 and 31 are attached to the bearing holes 27 and 27, the cartridge 30 can be rotated up and down around the support shafts 31 and 31.

This cartridge 30 has a mixed agent storage chamber 4
0 is formed. Also in the case of this example, the mixed agent storage chamber 40
Is partitioned into a mixed agent dissolution chamber 41 and an aqueous solution storage chamber 42. The dissolution chamber 41 is formed on one side of the cartridge 30 in the axial direction, and has a large volume. The dissolution chamber 41 contains ascorbic acid (vitamin C) as a chlorine neutralizer in the form of powder or granules 43. The aqueous solution storage chamber 42 is formed on the other side in the axial direction of the cartridge 30. The dissolution chamber 41 and the aqueous solution storage chamber 42 are separated by a water-permeable member that blocks the passage of the contaminant, for example, a nonwoven fabric or a mesh sheet 44. ing. The mesh sheet 44 allows the ascorbic acid granules 4
3 does not enter the aqueous solution storage chamber 42. However, the aqueous solution of ascorbic acid is free to pass through. In addition, an air vent hole is formed in the melting chamber 41, and the air vent hole is sealed by a stopper 45 in a gas-liquid tight manner.

An aqueous solution measuring chamber 46 is formed below the aqueous solution storage chamber 42 when the water purifier is pulled up into the air (in the case of FIG. 6). The measuring chamber 46 is in communication with the aqueous solution storage chamber 42 through an entrance 47. The internal volume of the measuring chamber 46 is set to be a little larger than the capacity of once using the aqueous solution. In this example, a structure is shown in which the measuring chamber 46 is formed so as to protrude outside the cartridge 30.
The measuring chamber 46 may be formed by providing a partition in the aqueous solution storage chamber 42.

The measuring chamber 46 has a discharge hole 48 formed on the outer surface thereof. The discharge hole 48 is for supplying the aqueous solution in the measuring chamber 46 to the outside of the cartridge 30.
In this case, the opening position of the discharge hole 48 is formed at a position lower than the upper end of the measuring chamber 46 by a predetermined dimension S when the measuring chamber 46 is located above as shown in FIG. The volume of the portion above the discharge hole 48 of the measuring chamber 46 is set so as to correspond to the amount of the ascorbic acid aqueous solution supplied once to the water in the bathtub. This volume is suitably, for example, about 2 to 5 ml. The size of the discharge hole 48 is such that the aqueous solution of ascorbic acid for one use can be released within a few minutes, and the aqueous solution does not leak due to the surface tension of the aqueous solution of ascorbic acid when in air. The size is set to, for example, 5 mm or less in diameter. Further, on the outer surface of the cartridge 30, for example, a float
9 are provided. The float 49 generates a biased buoyancy in the cartridge 30, and when the buoyancy is received, the cartridge 30 rotates up and down around the support shafts 31 and 31.

The operation of the water purifier of the second embodiment configured as described above will be described. A predetermined amount of ascorbic acid granules 43 is packed in the cartridge 30 in advance. The filling amount of the granules 43 is desirably such that the water purifier can be used for several tens or hundreds of times. Before use, the cartridge 30 is detached from the water purifier main body 20, and water is injected into the cartridge 30. To remove the cartridge 30,
The cover 22 is removed from the floating body 21, and the support walls 26, 26 formed on the floating body 21 are elastically deformed as shown by imaginary lines in FIG. Then, the bearing hole 2
7, 27 are separated from each other, so that these bearing holes 27, 2
7, the support shafts 26, 26 are disengaged.
0 can be removed. Cartridge 3 removed
In step 0, the stopper 45 is removed to open an air vent hole, and water is injected into the dissolution chamber 41 from the air vent hole. When injecting water,
When the cartridge 30 is submerged below the water surface with the air vent hole facing upward, the air in the dissolution chamber 41 rises and escapes out of the air vent hole, and at the same time, outside water flows into the dissolution chamber 41 through the air vent hole. . When no air bubbles come out of the melting chamber 41, the air vent hole is closed by the stopper 45, and the gas-liquid tightness of the melting chamber 41 is maintained.

In this way, water is injected into the entire mixed agent storage chamber 40 and the measuring chamber 46, and the ascorbic acid granules 43 stored in the dissolution chamber 41 are dissolved. In this case, the ascorbic acid contained in the dissolution chamber 41 is dissolved in water until the saturated concentration is reached, but further dissolution does not proceed, so that the remaining granules 43 do not dissolve and remain in a granular state. And
Since the specific gravity of the ascorbic acid granules 43 is large, the undissolved ascorbic acid granules 43 remaining in the dissolution chamber 41
Tends to sink below the melting chamber 41 and accumulates at the bottom of the melting chamber 43. When the cartridge 30 is filled with water as described above, the cartridge 30 is attached to the water purifier main body 20. When mounting, the support wall 2 formed on the floating body 21
6, 26 are elastically deformed as shown by the imaginary line in FIG. Then, the bearing holes 27, 27 are separated from each other, so that the support shaft 2 is located between the bearing holes 27, 27.
The support walls 26, 26 are elastically returned. Thereby, the cartridge 30 is rotatably supported by the support walls 26, 26. In this state, the cover 22 is attached from below the floating body 21 to cover the cartridge 30. This completes the preparation before use.

When the water purifier as described above is placed in the air, for example, with the flat surface 29 on the lower surface placed on the edge of the bathtub, in this case, the weight of the aqueous solution measuring chamber 46 and the float 49 provided in the cartridge 30 is reduced. In operation, the cartridge 30 moves the aqueous solution measuring chamber 46 and the float 49 to the lower position as shown in FIG. In this position, the aqueous solution of ascorbic acid dissolved in the contaminant dissolving chamber 41 flows through the mesh sheet 44 and flows into the aqueous solution storage chamber 42 extending horizontally, so that the aqueous solution in the aqueous solution storage chamber 42 has a high concentration. Has become. At this time, the ascorbic acid granules 43 remaining in the dissolution chamber 41 are
, Is prevented from flowing into the aqueous solution storage chamber 42. The aqueous solution measuring chamber 46 communicates with the aqueous solution storage chamber 42 through an inlet / outlet 47. Since the measuring chamber 46 is located below the storing chamber 42, the high-concentration ascorbic acid aqueous solution in the storage chamber 42 having a large specific gravity is used as the measuring chamber. Collect at 46. At this time, the outside of the discharge hole 48 is air, and if the aqueous solution tries to leak from the discharge hole 48, the inside of the measuring chamber 46 and the entire mixed agent storage chamber 40 communicating therewith tends to become negative pressure. This prevents the aqueous solution from leaking out of the measuring chamber 46 due to the pressure difference between the inside and outside. At the same time, surface tension of ascorbic acid is generated at the interface between the aqueous solution of ascorbic acid and air in the discharge hole 48, and the aqueous solution is prevented from leaking into the air from the measuring chamber 46. With this, when the water purifier is in the air,
No outflow of aqueous solution occurs.

Next, when such a water purifier is put into the water in the bathtub, water enters through water holes 24 formed in the water purifier body 20 and water holes 28 formed in the support wall 26.
Water enters through. At this time, the air in the water purifier main body 20 escapes from the air vent hole 25, so that the water purifier main body 20
Is filled with water. However, since the air chamber 23 is formed in the floating body 21 of the water purifier main body 20, the water purifier floats on the water surface. In this case, the draft line of the water purifier is determined by the buoyancy of the air chamber 23, but at least the entire cartridge 30 is immersed in water. Also, due to the buoyancy effect of the air chamber 23, the water purifier main body 20 always keeps the posture in which the floating body 21 is up and the lower cover 22 is down. Water purifier body 2
When the cartridge 30 is immersed in water due to the water that has flowed into the water 0, buoyancy is generated in the float 49, so that the cartridge 30 rotates, and the aqueous solution measuring chamber 46 rises as shown in FIG. In addition, outside water enters the discharge hole 48, and the water and the aqueous solution come into contact with the outside through the discharge hole 48. In this state, the surface tension stops working,
Since the specific gravity of the ascorbic acid aqueous solution is larger than water,
The aqueous solution in the measuring chamber 46 tends to descend due to the action of gravity.
Flow out of 8. At this time, instead of the outflow of the aqueous solution,
Water outside the cartridge 30 flows into the measuring chamber 46. As described above, the outflow of the ascorbic acid aqueous solution and the inflow of water occur at the same time, and the total amount of water in the contaminant storage chamber 40 does not decrease.

Since the aqueous solution of ascorbic acid which has flowed out of the cartridge 30 still has a large specific gravity, it flows downward in the water purifier main body 20 and passes through the water passage holes 24 and 2.
Through 8 is released to the water in the bathtub. If this water is agitated, ascorbic acid spreads throughout the bath and reacts with the free residual chlorine contained in the water to neutralize it. Since the aqueous solution of ascorbic acid released from the discharge hole 48 flows out due to a difference in specific gravity, a portion of the aqueous solution stored in the measuring chamber 46 located above the discharge hole 48 flows out. If this amount of aqueous solution flows out, the difference in concentration and specific gravity inside or outside the discharge hole 48 disappears or becomes small, so that the replacement of water stops. This terminates the release of the aqueous ascorbic acid solution. From this, one use corresponds to the volume of the portion located above the discharge hole 48 in the measuring chamber 46 when the measuring chamber 46 is located above, and if this volume is regulated, It is possible to control the amount of ascorbic acid released corresponding to one use.

When the supply of ascorbic acid is completed as described above, the water purifier may be pulled up and the flat surface 29 may be placed on the edge of the bathtub or the like as shown in FIG. At this time, the cartridge 30 rotates and returns, and as described above, the measuring chamber 46 is lower than the aqueous solution storage chamber 42, so that the high-concentration ascorbic acid aqueous solution in the storage chamber 42 flows into the measuring chamber 46 and is measured. The aqueous solution in the chamber 46 becomes highly concentrated. Therefore, the next release is replenished in the measuring chamber 46. In addition, the water or the low-concentration aqueous solution that has replaced the high-concentration aqueous solution and flowed into the storage chamber 42 is
It also enters the dissolution chamber 41 and dissolves the granules 43 that have not yet been dissolved, until they reach the saturation solubility. Therefore, the granules used once are dissolved.

As described above, if the cartridge 30 is turned upside down between when the water purifier is in the water and when the water purifier is pulled out of the water, the contents in the mixed agent storage chamber 40 are also turned upside down. The aqueous solution will be stirred. For this reason, even if a high concentration aqueous solution tends to sink down due to a difference in specific gravity, it can be stirred every time it is used, so that the concentration of the aqueous solution can be made uniform and the concentration variation of the released aqueous solution can be reduced. Can be prevented. Further, the undissolved ascorbic acid granules 43 remaining in the dissolution chamber 41 have a large specific gravity and thus tend to sink down and accumulate on the bottom of the dissolution chamber 43. On the other hand, if the cartridge 30 is turned upside down when the cartridge 30 is in the water and when the cartridge 30 is pulled out of the water, the undissolved granules 43 are relatively moved up and down as can be seen by comparing FIGS. Moving. Therefore, the granules 43 are also agitated, thereby preventing the granules 43 from being deposited in one place.

As described above, even in the water purifier of the second embodiment, the dissolution of ascorbic acid and the release of its aqueous solution are repeated each time it is used.
Until the ascorbic acid granules 43 stored in the
Can be used many times. From the above, it is possible to accurately supply the necessary and sufficient amount of ascorbic acid to neutralize the residual chlorine contained in the water in the bathtub, and to effectively use the amount of ascorbic acid contained in the dissolution chamber 41. And the water supply can be used for a long time. Also in such a water purifier, if at least the lower cover 22 and the cartridge 30 are made transparent, the undissolved ascorbic acid granules 43 remaining inside from outside can be seen through, so that ascorbin can be seen from outside. Since the remaining amount of the acid can be visually recognized, the cartridge 30 may be replaced when the remaining amount is exhausted.

In each of the above embodiments, the case where the present invention is applied to a submersible water purifier for a bath has been described. In such a case, it is preferable to increase the size of the discharge hole. However, in this case, there is a fear that the aqueous solution in the measuring chamber leaks through the discharge hole when the water is lifted from the water. To prevent this, it is desirable to provide an automatic opening / closing valve in the discharge hole. An example of this automatic opening / closing valve will be described with reference to FIG. That is, the on-off valve shown in FIG.
The ball valve 52 that moves by gravity inside or outside
The ball valve 52 is held by a holder 53 such as a net so as to be vertically movable. As shown in FIG. 9A, when the supply device is put into water, the ball valve 52 is lowered by gravity, so that the discharge hole 51 is opened. FIG.
(B) As shown in the figure, when the supply device is pulled up from the water and is turned upside down, the ball valve 52 is also lowered at this time, and in this case, the discharge hole 51 is closed. Therefore, the discharge hole 51 is opened in the water, but closed in the air.

In addition, when the camera is not upside down when it is underwater and when it is lifted from the water,
Instead of the ball valve, a float valve 55 as shown in FIG. 10 may be used. In such a case, as shown in FIG. 10A, when the supply device is put into water, the discharge hole 51 and the float valve 60 are immersed in the water, so that buoyancy is generated in the float valve 60, and the float valve 60 is floated. 60 moves upward to open the discharge hole 51. Then, as shown in FIG. 10B, when the supply device is pulled up into the air, the float valve 60 is lowered by gravity, and the discharge hole 51 is closed at this position. Therefore, the discharge hole 51 is opened in water and closed in the air.

The automatic opening / closing valve may employ various other means in addition to the ball valve 52 and the float valve 60, and may employ the ball valve or the float valve. The present invention can be implemented even with the above structure. In each of the above embodiments, the outer shapes of the water purifier main bodies 1 and 20 are each spherical, but this shape can be freely changed.
Animals such as fish and whales, boats, and various other forms are possible. In the configuration of the present invention, the material of each member is not limited to a synthetic resin, and a metal may be used if necessary.

For this reason, when supplying a mixed agent to water stored in a bathtub, a basin, and other water tanks, a necessary and sufficient amount of the mixed agent can be accurately supplied, and the mixed agent is stored in the mixed agent storage chamber. The contaminant can be used effectively, and the feeder can be used for a long time.
