Description

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 supplying flush water containing a chemical for preventing urine stones from adhering to a flush toilet and generating an odor from the toilet, and the like. More specifically, the present invention relates to a drug supply device using a solid drug.

[0002]

2. Description of the Related Art The above-described medicine supply apparatus is used by being connected to a main water supply passage for supplying flush water to a flush toilet in a public toilet, particularly a men's toilet, or a branch water passage branched from the main water supply passage. .

[0003] In general, a drug supply device that is widely used, when washing water is supplied to a toilet through a main water supply channel, takes in a part of the wash water into a container directly from the main water supply channel or through a branch water channel, and takes in the container. After dissolving the solid medicine stored in the container in advance in the washing water, the supply of the washing water to the toilet is stopped, and then the washing water containing the medicine is supplied from the device to the toilet.

[0004] Here, the chemical supply device of the type connected to the branch water channel has a simpler structure than that of the type (see Japanese Patent Laid-Open No. 10-8528) directly connected to the main water intake channel. There is an advantage that an operation of supplying the cleaning water containing the medicine after the supply of the cleaning liquid to the toilet is completed can be realized.

[0005] Further, there is a liquid drug as a drug used in the drug supply device, but a drug supply device using a solid drug can directly store the drug in the container for taking in the washing water as described above. Therefore, there is no need to provide a special container for holding the medicine, and the structure is simple, and the handling and replacement of the medicine are easy.

[0006]

Incidentally, in the above-described drug supply device, it is necessary to periodically exchange the drug before the solid drug completely runs out. In other words, it is necessary to discard the old solid medicine and replace it with a new solid medicine even though the old solid medicine can be used.
For this reason, there is a problem that the medicine is wasted and that it takes time to process the medicine to be discarded.

Further, when the solid medicine is placed directly on the bottom of the container for taking in the washing liquid, the surface area of the solid medicine that contacts the washing water is reduced. For this reason, the solid drug should be dissolved in the washing water in the container at a sufficient concentration during the time when the washing water is in the container, that is, in a short time from when the supply to the toilet bowl is started until the supply is stopped. May not be possible.

[0008] Further, in the above-mentioned drug supply device,
In many cases, a switching valve is installed to discharge the washing liquid containing the medicine to the outside of the container (that is, the toilet bowl) after the washing water is once taken into the container, but the solid medicine moves inside the container by the inflow and outflow of the washing water. There is a possibility that smooth operation of the device may be hindered by being caught on the operating portion of the switching valve.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a drug supply device of a type connected to a branch water channel is supplied through a container for accommodating a solid drug in a refillable manner and a branch water channel. And a switching valve for allowing the washing water in which the solid medicine has been dissolved to flow out into the branch channel after the washing water to flow into the container, and further, the solid medicine is stored and arranged in the container. At least two medicine placement sections are provided.

[0010] With this, even when the solid medicine is still left in one medicine placement section, a new solid medicine can be stored and arranged in another medicine placement section, so that each solid medicine can be completely used up. , Eliminating waste of medicine. In addition, when replenishing the solid drug, it is only necessary to place a new solid drug in the empty drug placement section,
Since it is not necessary to take out the old solid medicine from the container, the maintenance work can be facilitated and the processing of the old solid medicine is not troublesome. In the above invention, the medicine placement section (for example, two medicine placement sections) is provided on both sides of the switching valve in the container,
Regardless of where the solid medicine is placed, it is desirable that the solid medicine is uniformly dissolved by exposing the solid medicine to the same inflow and outflow of the washing water.

Further, in the above invention, a medicine support table (for example, a scaly table) for supporting the solid medicine in a state of being floated from the bottom surface of the container is provided in each medicine arrangement section, so that the solid medicine can be used for washing water. It is desirable to increase the contact surface area so that a sufficient concentration of a chemical-containing cleaning water can be produced even when the time from when the cleaning water starts flowing into the container to when the cleaning water ends is short.

Further, in the above invention, each medicine disposing portion is provided with a medicine stopper (for example, a comb-shaped portion facing the switching valve) for restricting the movement of the solid medicine in a direction approaching the switching valve. Accordingly, even when the solid medicine moves due to the inflow and outflow of the washing water into and from the container, it is desirable to surely prevent the situation where the solid medicine is caught by the switching valve.

Further, in the above invention, the fragrance support for supporting the fragrance is provided above the container, and the fragrance support allows the front side portion of the fragrance and the front upper end of the container to be connected to each other. In the meantime, the fragrance is tilted and supported so that a space for taking the solid medicine into and out of the container from the near side is made free, so that the fragrance does not interfere with taking the solid medicine into and out of the container. It is desirable to do so.

In this case, an air outlet for discharging the air in the exterior cover to the outside through the fragrance at a position above the fragrance in the exterior cover covering the fragrance supported by the container and the fragrance support. Is formed, the air pushed out from the inside of the container or the exterior cover by the inflow of the washing water into the container can be efficiently scented and smoothly discharged to the outside.

The opening / closing portion 20c that has been in close contact with b is separated therefrom. As a result, the chemical-containing cleaning liquid W in the container 11 starts flowing out of the container 11 to the toilet 1 through the water passage hole 25a and the branch pipe 4, and the valve movable body 20 is also reduced as the water level in the container 11 decreases. Move down gradually. In this way, most of the medicine-containing cleaning liquid W in the container 11 is supplied to the toilet 1 to prevent adhesion of urine stones to the toilet 1 and the like.

The container 11 of the medicine supply device 10 described above.
Usually, one solid medicine Y first passes through the upper end opening of the container 1 and one of the two medicine support bases 1.
4 and stored. Then, when the solid medicine (solid medicine on the left side in the figure) Y becomes smaller as shown in FIG.
The right side solid medicine (Y) is replenished through the upper end opening of the container 1. At this time, the reduced solid drug may be left as it is, and a new solid drug may be placed on the other drug support 14 of the two drug supports. By the time the newly replenished solid drug becomes smaller, the previous solid drug has completely disappeared, so that a newer solid drug may be placed on the one drug support 14. Again,
The solid medicine previously replenished may be left as it is.

As described above, with the use of the medicine supply device of this embodiment, a new solid medicine is replenished without removing the remaining solid medicine previously placed in the container 11 from the container 11 during maintenance. can do. Therefore, as compared with a conventional medicine supply device that takes out the remaining solid medicine and replaces it with a new solid medicine, maintenance is easier, and processing of the old solid medicine is not troublesome. Then, the old solid medicine left in the container 11 can be completely used up, and waste of the solid medicine can be prevented.

The solid medicine Y is replenished from the near side of the container 11 through the upper end opening. At this time, since the fragrance cassette 40 is obliquely leaned against the inclined surface 30a of the fragrance mounting table 30, the container is A space sufficient for replenishment of the solid medicine Y is formed between the upper end on the near side of 11 and the front side portion of the fragrance cassette 40. Therefore, the fragrance cassette 40 does not hinder the replenishment of the solid medicine Y.
