Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical supply device for flush toilets which is used by being mounted on the lid of a water storage tank type flush toilet.

[0002]

2. Description of the Related Art As a conventional medicine supply tool for flush toilets, one using a liquid medicine as shown in FIG. 3 has been proposed (JP-A-2-229333). That is, the flush toilet chemical supply tool 101 is equivalent to the auxiliary table 10
2 and the impregnation body 103 arranged on the auxiliary base 102,
It has a medicine container 104 arranged on the impregnated body 103. A liquid medicine is stored in the medicine container 104, and a lead-out hole 105 is provided at the lower end portion.

When using such a structure, the chemical supply tool 101 for flush toilet is arranged on the water tank top lid 106 of the flush tank type flush toilet and immediately below the water discharge tap 107. Then, when the water is discharged from the water discharge tap 107, the water flows down on the impregnated body 103 to dissolve the impregnated chemical, and then flows into the water storage tank through the hole 108 provided in the upper lid 106. The water in which the medicine that has flowed into the water storage tank is dissolved is supplied to the toilet bowl for the next flush.

Further, when the water is not discharged, the medicine led out from the lead-out hole 105 of the medicine container 104 is impregnated in the impregnating body 103 and then volatilized to generate a medicine effect in the surrounding space.

[0005]

However, in such a conventional flush toilet toilet chemical supply device, since water is made to directly flow down from the water discharge tap 107 onto the impregnated body 103, it is possible to perform a single water discharge. A large amount of the drug is washed away from the impregnated body 103. For this reason, the amount of the drug that is washed away per discharge of water becomes excessive and the drug is wasted, and the drug container 104 does not expire before the predetermined usable period expires.
The drug inside disappears early.

Further, the inside of the medicine container 104 becomes a negative pressure as the medicine contained therein decreases. Alternatively, under the condition that the ambient temperature is high and the internal temperature of the medicine container 104 is high accordingly, the water discharge tap 107 having a lower temperature than this.
When the water from the container flows down to the medicine container 104, the inside of the medicine container 104 becomes a negative pressure. Therefore, when water directly flows down onto the impregnated body 103, the water on the impregnated body 103 is sucked into the medicine container 104 due to the negative pressure of the medicine container 104. As a result, the drug in the drug container 104 is diluted with the lapse of the use period, and its concentration cannot be properly maintained until the end of use.

Further, the auxiliary base 102 is simply a top lid 106.
Since it is mounted on the water discharge port 107, it falls or is displaced due to the water pressure of the water flowing down from the water discharge tap 107. For this reason, it will not function normally due to the fall, and the water from the water discharge tap 107 will not flow down to the impregnation body 103 due to the positional deviation, and it will be impossible to dissolve the impregnated drug.

Therefore, as disclosed in the above publication and shown in FIG. 4, the impregnated body 103 is arranged to have a diameter much smaller than that of the medicine container 104, and the impregnated body 103 is arranged below the medicine container 104.
A structure in which the hole 108 of 06 is loosely fitted has also been proposed. According to this structure, the impregnated body 103 loosely fitted in the hole 108 can prevent the water from flowing down from the water discharge tap 107 to fall or be displaced.

On the other hand, however, since the main part of the impregnated body 103 is inserted into the tank through the hole 108, the amount of the drug volatilized from the impregnated body 103 into the surrounding space is small and the drug effect is generated in the surrounding space. I can't. Moreover,
Since all the water from the water discharge tap 107 always passes through the hole 108, all the water from the water discharge tap 107 comes into contact with the impregnated body 103. Therefore, similarly to the above, a single discharge of water causes a large amount of the drug to be washed away from the impregnated body 103, and the drug in the drug container 104 disappears early before the expiration of the predetermined usable period.

The present invention has been made in view of the above-mentioned conventional problems, and it is possible to dissolve a drug in an appropriate amount while volatilizing the drug sufficiently into the surrounding space without tipping or shifting.
Furthermore, it aims at providing the chemical | medical agent supply tool for flush toilets which can prevent the dilution of a chemical | medical agent.

[0011]

In order to solve the above problems, the present invention provides a main body of a supply tool arranged on a water tank upper lid of a water tank type flush toilet equipped with a water discharge tap, and a liquid medicine. And a drug holder to which the drug solution led out from the lead-out hole of the drug solution container is supplied, and the supply tool body has a bottom surface portion. and and a side wall diverging in the approximate substantially upward, the lower portion of the bottom portion, the reservoir legs loosely fitted into a hole in the tank lid is provided is provided, wherein from the water discharge tap on the bottom part A plurality of openings through which water that has flowed down flows into and out of the upper lid of the water storage tank is provided, a ventilation hole is provided in the side wall, and the medicine container has an upper end portion of the side wall of the supply tool body with the outlet hole facing downward. Fitted to the
The medicine holder is arranged on the bottom surface of the supply tool body and below the lead-out hole provided in the medicine container, and the medicine holder is provided on the upper surface of the supply tool body. A cover means is provided for covering. Alternatively, the main body of the supply tool arranged on the upper lid of the water storage tank of a water storage tank flush toilet equipped with a water discharge tap, a liquid medicine container containing a liquid medicine and a discharge hole for discharging the medicine, and the liquid medicine The supply tool main body is provided with a drug holding body to which the drug solution led out from the lead-out hole of the container is supplied, and the supply tool main body has a bottom end coupled to the bottom face and an upper end located outside the lower end. And a side wall, and a leg portion that is loosely fitted in a hole provided in the water storage tank upper lid is provided at a lower portion of the bottom surface portion, and the leg portion flows down from the water discharge tap onto the water storage tank upper lid. A plurality of openings through which water flows in and out are provided, and a vent is provided in the side wall,
The medicine container is fitted to the upper end of the side wall of the supply tool body with the outlet hole facing downward, and the medicine holder is

Therefore, the leg portion loosely fitted in the hole of the water storage tank upper lid provided on the bottom surface portion of the supply tool body prevents the tipping device from falling and maintains a proper use state. Further, the medicine led out to the medicine holder from the lead-out hole of the medicine container is volatilized to the outside from the ventilation hole provided in the peripheral portion of the supply tool main body, whereby a sufficient medicine effect is generated in the surrounding space.

Further, since the upper surface of the supply tool body is provided with the cover means for covering the medicine holder above the water, the water from the water discharge tap does not flow down directly to the medicine holder. Excessive drug washout due to direct water flow is prevented.

That is, the water from the water discharge tap flows down onto the tank upper lid, then flows in through the opening provided in the bottom surface portion, and dissolves the medicine led out to the medicine holder. Therefore, not all water always flows in through the opening, and the amount of water that flows in can be controlled according to the area of the opening. Therefore, the amount of the dissolved drug can be controlled and appropriately maintained by the amount of inflowing water.

Further, since the water from the water discharge tap does not flow down onto the medicine holder in this way, the inside of the medicine container becomes negative pressure due to the decrease of the medicine contained therein, and the water discharge tap is discharged. Even if the water is cooled to a negative pressure, the water flowing down on the drug holder will not be sucked into the drug container. Therefore, the drug in the drug container is not diluted with the lapse of the use period, and its concentration is appropriately maintained until the end of use.

Further, the present invention is further provided with a guide member for guiding the water into the opening. Therefore, not only the area of the opening but also the size and angle of the guide member can be used to control the amount of water flowing in delicately. Therefore, the amount of the dissolved drug can be maintained more appropriately by finely controlling the amount of water flowing in.

The drug container 7 is fixed and set to the supply tool main body 2 by engaging the concave portion 73 with the convex portion 61 of the cover member 6.

When the medicine container 7 is set in the supply tool main body 2 in this manner, the long leg portion 27 is loosely fitted into the hole 108 of the water storage tank upper lid 106 of the water storage tank flush toilet, and the short leg portion is attached. By bringing 33 into contact with the water storage tank upper lid 106 at the peripheral portion of the hole 108, the flush toilet chemical supply tool 1 is put into use. In this usage state, the drug impregnated in the impregnated body 4 is volatilized to the outside through the ventilation port 36, whereby a sufficient drug effect can be generated in the surrounding space.

In this state of use, the water discharge tap 107
When water is discharged from the water discharge tap 107 (see FIG. 3),
Is directly above the hole 108, the water from the water discharge tap 107 directly flows down to the flush toilet chemical supply tool 1, and the flush toilet chemical supply tool 1 receives water pressure. However, since the long leg 27 is loosely fitted in the hole 108 of the water storage tank upper lid 106, the flush toilet chemical supply tool 1 does not fall down even if water pressure is applied, and the normal use state is maintained. be able to.

The upper part of the impregnated body 4 is covered with the drug container 7 on the front side and with the cover member 6 on the back side. Therefore, the tap 10
Even if the water directly flows down from 7 into the flush toilet chemical supply tool 1, it does not flow down directly into the impregnated body 4, and the excess flow of the chemical due to the direct flow of water is prevented.

Further, since the water from the water discharge tap 107 does not flow down onto the impregnated body 4 as described above, even if the inside of the medicine container 7 becomes negative pressure due to the decrease of the medicine contained therein. Also, the phenomenon that water flowing down on the impregnated body 4 is sucked into the medicine container does not occur. Therefore, the medicine in the medicine container 7 is not diluted with the lapse of the use period, and its concentration can be appropriately maintained until the end of use.

The water from the water discharge tap 107 is obstructed by the baffle plate 30 when the water flows along the surface of the tank water storage tank upper lid 106 in the direction of the hole 108, and the water flows from the inflow opening 31. It flows into the supply tool body 2.
The water that has flowed into the supply tool main body 2 dissolves the drug impregnated in the impregnating body 4, and then the outflow opening 3
2 and the circular hole 26, flows down from the hole 108 into the water storage tank, and is stored in the water storage tank.

At this time, not all of the water discharged from the water discharge tap 107 flows into the supply tool main body 2 through the inflow opening 31, and the amount of water flowing into the supply tool main body 2 does not flow. The amount depends on the area of the opening 3 for use and the size and angle of the baffle plate 30. Therefore, the inflow opening 3
The amount of inflowing water can be controlled by designing while tuning the area, the size and angle of the baffle plate 30. Therefore, depending on the amount of inflowing water, the impregnated body 4
It is possible to control the amount of the drug dissolved from the drug and maintain it appropriately.

When the amount of water discharged from the water discharge tap 107 per unit time is large, water not only flows in through the inflow opening 31 and flows out through the outflow opening 32 and the circular hole 26, but also on both sides. It flows in or out through the opening 35. Therefore, in this case, the inflow amount of water into the supply tool main body 2 increases, and the dissolution amount of the drug from the impregnated body 4 also increases. Therefore, each user can adjust the amount of the drug dissolved from the impregnated body 4 by adjusting the amount of water discharged from the water discharge tap 107 per unit time by the user.

In this embodiment, the front surface 2
Although the vent hole 36 is provided in the second portion, it may be provided in the back face portion 23 or the left and right side face portions 24, 25. Also,
In the present embodiment, the medicine container 7 and the cover member 6 constitute the covering means, but the covering means may be constituted only by the medicine container 7.

[0037]

As described above, according to the present invention, the bottom portion of the supply tool body is provided with the leg portion which is loosely fitted in the hole of the water storage tank upper lid, so that the fall and the displacement are prevented. It is possible to maintain a proper use state. Since the vent hole is provided in the peripheral part of the supply tool main body, the drug guided to the drug holder is volatilized to the outside,
A sufficient drug effect can be generated in the surrounding space. Since the cover means for covering the upper side of the drug holding body is provided, it is possible to prevent the water from the water discharge tap from directly flowing down to the drug holding body, and prevent the excess drug from being washed away by the direct water flowing down. You can As a result that water from the water discharge tap can be prevented from flowing down directly to the drug holder, the inside of the drug container becomes a negative pressure due to the reduction of the drug contained and cooling by the water from the water discharge tap. The phenomenon that water is sucked into the drug container does not occur, and the drug concentration in the drug container can be appropriately maintained until the end of use. Since the bottom of the supply tool body has an opening through which water that flows down from the tap to the top of the water storage tank enters and exits, the amount of water that flows in can be controlled according to the area of the opening. The amount of the dissolved drug can be controlled by controlling the amount of inflowing water, and the amount of the dissolved drug can be appropriately maintained.

Therefore, from the above, it becomes possible to dissolve the drug in an appropriate amount and prevent the drug from being diluted, while sufficiently volatilizing the drug into the surrounding space without falling or shifting.

Further, since the guide member for guiding the water flowing down from the water discharge tap onto the upper lid of the water storage tank is further provided in the opening, not only the area of the opening but also the size and angle of the guide member The amount of inflowing water can be controlled subtly. Therefore, the amount of the dissolved drug can be maintained more appropriately by finely controlling the amount of inflowing water.
