DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical dispenser for flush toilets which is used by being placed on a top cover of a flush tank of a flush tank type flush toilet.

[0002]

2. Description of the Related Art As a conventional chemical supply device for flush toilets, for example, the one shown in FIG. 4 is known. This flush toilet chemical supply device has a supply device main body 50 for storing a water-soluble drug, and the supply device main body 50 has an open upper surface, and a water storage tank of a water storage tank type flush toilet at a central portion on a bottom surface. A plurality of legs 53 are vertically provided to fit loosely into holes 52 provided in the upper lid 51. Further, a medicine placing portion 54, a lower through hole 55, and a hook portion 56 are formed on the bottom surface, and a plurality of windows 57 are formed on the peripheral surface. Inside the supply tool main body 50, a water-soluble drug 58 is mounted on the drug mounting portion 54, and the water-soluble drug 58
A middle cap 59 surrounding the upper and peripheral portions of the
The lower end of the middle cap 59 is locked by the hook 56.

[0003] A volatilizer 60 is detachably fitted to the upper part of the supply tool body 50. The volatile body 60 has a dome-shaped cover member 61 and a filter paper 62 stretched at the lower end of the cover member 61, and contains a jelly-like fragrance 63 therein.

In such a configuration, in use, after the water-soluble drug 58 is placed on the drug placing portion 54, the middle cap 59 is locked to the hook portion 56, and the volatile material 60
Is fitted on the upper part of the supply tool main body 50, and then the leg 53 is loosely fitted into the hole 53, and is placed on the water storage tank upper lid 51. Then, the drug component that has permeated the filter paper 62 volatilizes from the fragrance 63, and the volatilized drug component diffuses through the window 57 to generate a fragrance effect in the surrounding space.

When water is discharged from the water discharge tap of the flush toilet, when the water stays on the water tank upper cover 51, the water flows into the supply tool main body 50 from the lower through hole 55. Then, after dissolving the water-soluble drug 58, it flows out, flows down from the hole 52 into the water storage tank, and is stored in the water storage tank. At this time, since the water-soluble drug 58 is surrounded by the middle cap 59, a large amount of water stays in the water tank upper cover 51, and the supply device main body 50 is opened from the window 57.
Even if the water flows into the inside, the flowing water flowing through the window portion 57 is restricted from flowing directly into contact with the peripheral surface of the water-soluble drug 58.

Accordingly, the water staying in the supply tool main body 50 enters the middle cap 59 from the bottom of the middle cap 59 as the water level rises, and the water-soluble drug 58 as the water level rises. Is immersed in the non-fluid water in the middle cap 59. As described above, the water-soluble drug 58 is immersed in the non-fluid water that rises in the middle cap 59 without coming into contact with the fluid water that has flowed into the supply device main body 50, and
An appropriate amount can be dissolved each time water is discharged. Further, if the middle cap 59 is locked to the hook portion 56, even if a large amount of water flows into the supply tool main body 50, the middle cap 59 does not float, and water is reliably regulated. be able to.

Further, since the movement of the water-soluble drug 58 is regulated by the middle cap 59, the water-soluble drug 58 can be always positioned on the drug mounting portion 54, and this also enables Dissolution of an appropriate amount is ensured.

[0008]

However, in such a conventional medicine supply device for flush toilet, it is necessary to lock the middle cap 59 on the hook when using the same, and this operation is performed by the user. It becomes troublesome for. For this reason, the user may neglect this complicated work or may start using it without performing the locking operation properly. In this case, a large amount of water is supplied from the window 57 into the supply device main body 50. , The middle cap 59 floats, and the water regulation effect of the middle cap cannot be obtained. As a result, water comes into contact with the peripheral surface of the water-soluble drug 58, and the water-soluble drug 5 is excessively dissolved, and the water-soluble drug 58 is quickly lost before a predetermined usable period has expired.

In addition, as described above, in the flush toilet chemical supply device, the water-soluble chemical 58 is immersed in the non-fluid water rising in the water level in the middle cap 59 so that an appropriate amount is dissolved each time water is discharged. Since the amount of water discharged from the water discharge tap of the flush type flush toilet is set to a small amount and sufficient water does not stay in the water storage tank upper cover 51, or due to the shape of the water storage tank upper cover 51, If sufficient water does not stay on the surface 51, the amount of water flowing from the lower through-hole 55 and the window portion 57 into the supply device main body 50 will be too small. As a result, the drug is not sufficiently dissolved from the water-soluble drug 58, the solution concentration of the water-soluble drug 58 becomes low, and a sufficient drug effect such as a cleaning effect cannot be obtained.

Moreover, since the volatile element 60 is a so-called disposable type in which a jelly-like fragrance 63 is filled in a container formed of a cover member 61 and a filter paper 62, when the fragrance 63 is used up, the container is discarded. I have to do it. Therefore, this contributes to an increase in garbage and also increases the use cost.

The present invention has been made in view of such a conventional problem, and is capable of dissolving a water-soluble drug in an appropriate amount without being affected by the amount of water from a water discharge tap. It is an object of the present invention to provide a medicine supply device for a flush toilet that can sufficiently generate a medicine effect on a surrounding space and can be used at low cost.

[0012]

According to the present invention, in order to solve the above-mentioned problems, the present invention can be arranged on a water tank upper lid of a water tank type flush toilet, and a medicine mounting portion and a lower through hole are provided on a bottom surface. Is provided and a window is provided on the peripheral surface, and an upper release for bringing water from a water discharge tap into contact with a water-soluble drug disposed on the drug mounting portion via the lower through hole and the window. -Shaped lower member, and a flat plate portion detachably fitted to an upper portion of the lower member, and a cylindrical shape surrounding the water-soluble drug placed on the drug mounting portion on the flat plate portion. A vertically extending portion, an intermediate member having a peripheral through-hole formed in a peripheral portion of the cylindrical portion of the flat plate portion, and a container body having an open bottom surface, which is detachably coupled to the intermediate member. And an upper member for containing therein a volatile drug.

In such a configuration, when water flows out of the water discharge tap of the flush flush toilet, the water flows into the lower member through the lower through hole and the window when staying on the upper lid of the tank water storage tank. Then, after dissolving the water-soluble drug, it flows out, flows down into the water storage tank, and is stored in the water storage tank. At this time, since the periphery of the water-soluble drug is surrounded by the cylindrical portion, even if a large amount of water flows into the lower member from the window portion, the peripheral surface of the flowable water-soluble drug flows into the lower member. Is restricted by the cylindrical portion. Therefore, in the cylindrical portion, water staying in the lower member invades from the bottom of the cylindrical portion as the water level rises, and as the water level rises, the water-soluble drug does not flow in the cylindrical portion. Immersion in natural water, so that an appropriate amount is dissolved each time water is discharged. In addition, since the tubular portion is suspended from the intermediate member, even if a large amount of water flows into the lower member, the tubular portion does not float, and the water is reliably regulated. Since the movement of the water-soluble drug is regulated by the state of the cylinder, the water-soluble drug can always be positioned on the medicine mounting portion, and this also ensures the appropriate amount of dissolution for each water discharge. You.

Further, in the present invention, an upper through-hole is formed in an upper portion of the upper member, and the medicine contained in the upper through-hole is solid and insoluble in water. For this reason,
Water discharged from the water discharge tap onto the upper member flows into the lower member via the upper through-hole and the peripheral through-hole. Therefore, the amount of water discharged from the water tap is set to a small amount,
Even when sufficient water does not stay in the upper lid of the tank water storage tank, water can flow into the lower member to dissolve the water-soluble drug, thereby ensuring the dissolution of the water-soluble drug. At this time, since the peripheral through-hole is formed outside the cylindrical portion, the water that has passed through the peripheral through-hole does not flow down onto the water-soluble drug but flows down into the lower member, and Stay in the member.

[0015] Therefore, water staying in the lower member enters the cylindrical portion from the bottom of the cylindrical portion as the water level rises, and as the water level rises, the water-soluble drug is introduced into the cylindrical portion. Soak in non-fluid water. Therefore, as in the case where water enters the lower member through the lower through-hole or the window, the water-soluble drug does not come into contact with the fluid water but is immersed in the non-fluid water, so that a predetermined amount of The drug dissolves. as a result,
Not only when the amount of water remaining in the water storage tank lid is excessive, but also when the amount of water from the water discharge tap is small or when sufficient water does not stay due to the shape of the tank water storage tank lid, one water discharge Each time, the water-soluble drug can be dissolved in an appropriate amount. Since the medicine in the upper member is insoluble in water, even if water enters the upper member through the upper through hole, it is not affected.

On the other hand, the drug component of the solid particulate water-insoluble drug having volatility in the upper member not only diffuses to the surroundings through the peripheral through hole of the intermediate member and the window of the lower member, but also It diffuses directly into the surrounding space from the upper through hole provided in the upper member. Further, when water discharged from the water discharge tap onto the upper member flows into the lower member through the upper through-hole and the peripheral through-hole, the air also flows with the flow of the water. Facilitates diffusion of the water-insoluble drug around the drug component. Therefore, the volatilization efficiency is improved, and the medicine effect is sufficiently generated in the surrounding space. Also, the intermediate member and the upper member are detachable,
Since the non-water-absorbing agent is in the form of solid particles, when its effect is lost, only the non-water-absorbing agent needs to be replaced.

According to the present invention, the upper member has an uneven portion extending from the center of the upper surface to the periphery.
The upper through hole is formed in the concave portion. Therefore,
The water that has flowed down from the water discharge tap onto the upper member flows through the concave portion, and when flowing through the concave portion, flows into the upper member from the upper through hole, and as described above, from the peripheral through hole to the lower member. Run down. Therefore, even if the amount of water from the water discharge tap is small, it is possible to reliably flow the water into the lower member and dissolve the water-soluble drug.

In the present invention, since the water-insoluble drug is composed of an aggregate of a granular fragrance and a deodorant, a fragrance effect and a deodorant effect are generated in the surrounding space. Further, the upper member is transparent, and the water-insoluble drug is composed of granules of different colors. Therefore, a plurality of colored particles accommodated in the upper member can be seen from the outside, and thereby can function as a decorative article. At this time, every time there is water discharge from the water discharge tap,
Since water flows into the upper member through the upper through-hole and cleans the surface of the granular material, dust and dirt do not adhere to the surface of the granular material, and the granular material is maintained in a beautiful state. You.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIGS. 1 and 2, the flush toilet chemical supply device 1 has a lower member 2, an intermediate member 3, and an upper member 4. The lower member 2 is a circular member in a plan view, and is a top open member having a bottom surface 5 and a peripheral surface 6 integrally. A circular hole 7 is formed at the center of the bottom surface 5, and a plurality of holes which are loosely fitted around the circular hole 7 into holes 52 provided in a water tank upper lid 51 of a water tank type flush toilet. A long leg 8 and a short leg 9 abutting on the water tank upper lid 51 are vertically provided. Furthermore, on the bottom surface 5, these legs 8, 9
A lower through-hole 10 is radially formed between the lower through-hole 10 and a plurality of radial ribs provided slightly above the lower through-hole 10 to form a medicine placement section 11.

A water-soluble medicine 12 having a truncated cone shape is placed on the medicine placement section 11. Various detergents, bleaching agents, oxygen agents, bactericides, repellents, insecticides, air cleaners, deodorants, deodorants, blue dyes, and the like are appropriately selected and mixed into the water-soluble drug 12. Oil. Then, the water-soluble drug 12 is such that the water staying in the lower member 2 invades from the bottom of a tubular portion 20 described later with the rise of the water surface,
As the water level rises, the water-soluble drug 12 is immersed in the non-fluid water in the cylindrical portion 20, so that an appropriate amount is dissolved each time water is discharged.

A plurality of windows 13 are formed on the peripheral surface 6 of the lower member 2 at appropriate intervals in the circumferential direction, and a support piece 14 is formed on each of the windows 13. . The upper edge of the peripheral surface 6 is formed in a wavy shape, and a pair of protrusions 15 is provided on the inner surface thereof.

On the other hand, the intermediate member 3 has a disk-shaped flat plate portion 16.
, And a flange 17 is suspended from the periphery thereof. An external thread 18 is formed on the surface of the flange 17, and a protruding edge 19 is formed at the lower end of the flange 17 so as to be removably fitted between the support piece 14 and the projection 15. On the lower surface of the flat plate portion 16, a tubular portion 20 surrounding the water-soluble drug 12 placed on the drug loading portion 11 is vertically provided integrally. When the intermediate member 3 is fitted on the upper portion of the lower member 2, the lower end portion of the cylindrical portion 20 has a length in contact with the bottom surface 5 of the lower member 2. And a plurality of notches 21 are provided. Further, the flat plate portion 16 has a plurality of ventilation holes 28 formed inside the cylindrical portion 20 and a peripheral through hole 22 formed between the cylindrical portion 20 and the flange 17.
The peripheral through-hole 22 includes a plurality of radially formed slits.

On the other hand, the upper member 4 is a container having a bottom opening formed of a colorless and transparent resin, and has a dome shape. The surface of the upper member 4 is formed in a concave-convex shape in which concave portions 23 and concave portions 24 extending in a curved manner from the center of the upper surface to the peripheral portion extend alternately. Are formed at equal intervals. Each upper through-hole 25 has a curved shape and is provided in the concave portion 23 as shown in FIG. A female screw portion 26 is formed on the inner peripheral portion of the lower end of the upper member 4.
The upper member 4 is detachably connected to the intermediate member 3 by screwing the 6 into the male screw portion 18.

A water-insoluble drug 27, which volatilizes and generates an aroma effect and a deodorizing effect in the surrounding space, is accommodated in an internal space formed by coupling the intermediate member 3 and the upper member 4. The water-insoluble drug 27 is composed of an aggregate of blue granules and white granules, one of which is a fragrance and the other is a deodorant. This characteristic does not change. In FIG. 2, reference numeral 30 denotes a water discharge tap of a water-storage type flush toilet disposed above the water storage tank upper lid 51.

In the present embodiment having the above-described structure, the lower member 2, the intermediate member 3, and the upper member 4 are separated when the flush toilet chemical supply device 1 is used. Then, the upper member 4 is reversed and the water-insoluble drug 27 is charged therein, and the female screw part 26 and the male screw part 18 are screwed together while the upper member 4 is kept reversed. Thus, the water-insoluble drug 27 is stored inside the upper member 4 closed by the intermediate member 3.

Next, the water-soluble drug 12 is placed on the drug placement portion 11 of the lower member 2, and the protruding edge 19 is connected to the support piece 14 and the projection 1.
5 is fitted. Thereby, both screw parts 18, 2
The intermediate member 3 and the upper member 4 which are integrated by 6 are combined with the lower member 2, and three separate members 2, 3, and 4 are integrated. Then, as shown in FIG. 2, the long leg 8 is loosely fitted in a hole 52 provided in the water tank upper lid 51 of the water tank type flush toilet, and the short leg 9 is fitted around the hole 52 at the periphery of the water tank. It is brought into a use state by bringing it into contact with the upper lid 51.

In this state of use, when water is discharged from the water discharge tap 30, the water flows into the lower member 2 through the lower through hole 10 and the window 13 when staying on the tank water storage tank upper lid 51, After dissolving the water-soluble drug 12, it flows out, flows down into the water storage tank, and is stored in the water storage tank. At this time, since the periphery of the water-soluble drug 12 is surrounded by the cylindrical portion 20, even if a large amount of water flows into the lower member 2 from the window 13, the flowing water-soluble drug 12 is restricted from contacting the peripheral surface. Therefore, water that has accumulated in the lower member 2 enters the cylindrical portion 20 through the cutout portion 21 as the water level rises, and at this time, the air in the cylindrical portion 20 passes through the ventilation holes 28. By being led out, the water surface in the cylindrical portion 20 rises, and the water-soluble drug 12 is immersed in the non-fluid water in the cylindrical portion 20 with the rise of the water surface, so that one time The proper amount dissolves with each water discharge.

Further, since the cylindrical portion 20 is suspended from the intermediate member 3, a complicated operation for locking the middle cap 59 to the hook portion 56 as in the conventional case shown in FIG. In addition, by starting to use without neglecting or performing this complicated operation properly, the middle cap 59 will not float, and the water regulation effect will not be lost.
Therefore, even if a large amount of water flows into the lower member 2, the water can be reliably regulated, and further, the cylindrical portion 2
Since the movement of the water-soluble drug 12 is regulated by 0,
The water-soluble drug 12 can always be positioned on the predetermined drug mounting portion 11, and thus the water-soluble drug 12 can be dissolved in an appropriate amount every time water is discharged.

Further, since the upper member 4 is provided with the upper through hole 25 and the intermediate member 3 is provided with the peripheral through hole 22, the water is discharged from the water discharge tap 30 onto the upper member 4. After the water flows down into the upper member 4 through the upper through hole 25, it flows into the lower member 2 through the peripheral through hole 22. At this time, since the peripheral through-hole 22 is formed outside the cylindrical portion 20, the water passing through the peripheral through-hole 22 does not flow down to the water-soluble drug 12, and the lower member 2
And stays in the lower member 2.

Therefore, the water staying in the lower member 2 enters the cylindrical portion 20 through the notch portion 21 as the water level rises, and the water-soluble drug 12 flows into the cylindrical portion 20 as the water level rises. Immerse in the non-fluid water in the shape 20. Therefore, similarly to the case where water enters the inside of the lower member 2 from the lower through-hole 10 and the window 13, the water-soluble drug 12 is immersed in non-fluid water without coming into contact with fluid water. , A predetermined amount of the drug dissolves. Therefore, even when the amount of water from the water discharge tap 30 is small, or when sufficient water does not stay on the upper lid 51 due to the shape of the tank water storage tank upper lid 51,
The water-soluble drug 12 can be dissolved in an appropriate amount every time water is discharged.

In addition, the upper member 4 has a recess 23 radially formed on the upper surface thereof.
Is formed, the water flowing directly from the water discharge tap 30 onto the upper member 4 is guided by the concave portion 23 and radially flows on the upper member 4, and when flowing through the concave portion 23, It flows into the upper member 4 from the upper through hole 25 and flows into the lower member 2 from the peripheral through hole 22. Therefore, even when the amount of water from the water discharge tap 30 is small, the water-soluble drug 12 can be reliably dissolved in an appropriate amount. Therefore, not only when the amount of water from the water discharge tap 30 is excessive and the amount of water staying in the water tank upper cover 51 is excessive, but also on the contrary, the amount of water from the water discharge tap 30 is too small and stays in the water tank upper cover 51. Even when the amount of water is too small, the water-soluble drug 12 can be surely dissolved in an appropriate amount each time water is discharged. However, the water-insoluble drug 27 in the upper member 4 is not affected even if water enters the upper member 4, and the effect of the water-insoluble drug 27 is not hindered.

When a large amount of water is discharged from the water discharge tap 30, the water covers the entire surface of the upper member 4,
The fluid flows radially in the circumferential direction while being guided by the concave portions 23 and the convex portions 24 along the surface of the upper member 4. At this time, the water covers the entire surface of the upper member 4 to form a water film on the surface. However, since the upper member 4 has the concave portions 23 and the convex portions 24, the water film is formed in the concave portions. 23, and is thicker on the protrusion 24. For this reason, if the upper through-hole 25 is formed in the convex part 24, the splash of water flowing on the upper member 4 and abutting on the edge of the upper through-hole 25 will not be blocked by the thin water film, but will Water splashes on the floor around the water storage tank. However, when the upper through-hole 25 is formed in the concave portion 23, the water droplets flowing on the upper member 4 and contacting the edge of the upper through-hole 25 are prevented from being scattered by the thick water film, and the water storage tank No water droplets scatter on the surrounding floor. Therefore, by forming the upper through-hole 25 in the concave portion 23,
Water can be guided into the upper member 4 while preventing water droplets from scattering around.

On the other hand, the drug component of the solid particulate water-insoluble drug 27 having volatility enters the lower member 2 through the peripheral through hole 22 of the intermediate member 3, and the window 13 of the lower member 2 is opened. Not only does it diffuse to the surroundings through the upper member 4, but also to the surrounding space directly from the upper through hole 25 provided in the upper member 4.
Further, when the water discharged from the water discharge tap 30 onto the upper member 4 flows into the lower member 2 through the upper through-hole 25 and the peripheral through-hole 22, the air also flows with the flow of the water. Therefore, the diffusion of the water-insoluble drug around the drug component is promoted by the flow of the air. Therefore, the volatilization efficiency is improved, and the fragrance effect and the deodorant effect can be sufficiently generated in the surrounding space.

Further, the intermediate member 3 and the upper member 4 are detachable with both screw portions 18 and 26, and the non-
Since the effect is lost, the intermediate member 3 and the upper member 4 are separated by the two screw portions 18 and 26, and only the non-water-absorbing agent 27 needs to be replaced.
Therefore, unlike the related art, it is not necessary to discard the container every time the fragrance effect is lost, and it is possible to prevent the generation of dust and to reduce the use cost.

Further, since the upper member 4 is transparent and the water-insoluble drug 27 is composed of an aggregate of blue particles and white particles, a plurality of The colored granules can be seen from the outside, and thus can function as a decorative article. At this time, every time water is discharged from the water discharge tap 30, water is supplied to the upper through-hole 25.
Since it flows into the upper member 4 and cleans the surface of the water-insoluble drug 27, dust and dirt do not adhere to the surface of the granular material, and the granular material is maintained in a beautiful state. .
Therefore, the decorative effect in the toilet can be enhanced by the water-insoluble drug 27 which always forms a beautiful granular material.

In the present embodiment, the water-insoluble drug 27 is an aggregate of blue granules and white granules, and uses an fragrance and a deodorant. One kind or more kinds of medicines may be accommodated, and a single kind or more kinds of granules may be used for the color. In addition, water-insoluble drug 2
7 is not limited to a granular material, and may be a single solid or a plurality of solids.

[0037]

As described above, according to the present invention, since the tubular portion surrounding the water-soluble drug placed on the lower member is suspended from the intermediate member, it is possible to control the operation by the user. While restricting the contact of the water with the water-soluble drug without fail and regulating the position of the water-soluble drug,
The water-soluble drug can be dissolved by the non-fluid water, and the amount of the water-soluble drug dissolved can be appropriately optimized for each water discharge. Further, since the water flowing down on the upper member flows down into the lower member at the periphery of the cylindrical portion via the intermediate member, the amount of water discharged from the water discharge tap is small, Even when sufficient water does not stay in the tank top lid, water can flow into the lower member. At this time, it is possible to prevent the water from being dropped onto the water-soluble drug by the tubular portion, and to immerse the water-soluble drug in non-fluid water that has risen in the tubular portion. Therefore,
Not only when the amount of water is excessive, but also when the amount of water is insufficient, it is possible to dissolve the water-soluble drug in an appropriate amount each time water is discharged.

Further, not only can the drug component of the solid particulate water-insoluble drug having volatility be diffused to the surroundings through the peripheral through-hole of the intermediate member and the window of the lower member, but also to the upper member. It can be diffused directly into the surrounding space from the upper through hole provided. Furthermore, when the water flowing down on the upper member flows down into the lower member via the intermediate member, air also flows with the flow of the water. Diffusion of the components to the surroundings can be promoted, so that the volatilization efficiency can be improved and the drug effect can be sufficiently generated in the surrounding space.

Further, since the intermediate member and the upper member are detachable and the non-water-absorbing agent is made into solid particles, the non-water-absorbing agent can be refilled. Therefore, the generation of dust can be suppressed, and the use cost can be reduced.

Further, according to the present invention, since the upper member has an uneven portion extending from the center of the upper surface to the peripheral portion, and the upper through hole is formed in the concave portion, the water from the water discharge tap can be reliably discharged. It is possible to flow into the upper member from the upper through hole, and it is possible to more reliably dissolve the water-soluble drug even when the amount of water from the water discharge tap is small. Further, by forming the upper through hole in the concave portion, water can be guided into the upper member while preventing water droplets from scattering around.

Furthermore, since the water-insoluble drug is an aggregate of a granular fragrance and a deodorant, an aroma effect and a deodorant effect are generated in the surrounding space, and the cleaning effect by the water-soluble drug is not improved. In combination, it is possible to provide an ideal medicine supply device to be disposed in a toilet.

Further, since the upper member is transparent and the water-insoluble drug is made into a granular material of a plurality of different colors, water flows into the upper member from the upper through hole every time water is discharged from the water discharge tap. By cleaning the surface of each of the granules, the granules are maintained in a beautiful state, and an excellent function as a decorative article can be generated.
