Description

TECHNICAL FIELD The present invention relates to a drug supply tool that is used by being hung on the edge of a flush toilet, and particularly to a drug supply tool suitable for a tornado type or semi-tornado flush toilet.

As shown in FIG. 7, a so-called semi-tornado type {FIG. (a)} and a tornado type {FIG. (c)} are known as specifications of flush toilets (method of flowing flush water). The semi-tornado type is a method in which wash water is spouted diagonally downward along the inner surface of the toilet from a number of outlets provided along the upper edge of the toilet, while the tornado type is installed on the inner side of the upper edge of the toilet. This is a method in which flush water is jetted horizontally along the inner surface of the toilet from one jet outlet.

As a supply tool for supplying a medicine for cleaning, disinfecting, deodorizing, aromatizing, etc. of the flush toilet as described above, a supply tool of a type in which a container portion containing the medicine is hung on the edge of the toilet bowl is used. It is known (for example, Patent Documents 1 and 2). The container portion has a plurality of openings through which flush water can pass, and is placed at a desired position in the flush toilet in a state of being suspended by a hook that can be locked to the edge of the toilet bowl.

For example, in the medicine supply tool of Patent Document 1, in a state of being hung on the edge of the toilet bowl, the front portion of the container portion facing the center side of the toilet bowl and the rear portion of the container portion facing the inner surface side of the toilet bowl are respectively vertically moved. A linear slit-shaped opening that extends is provided. A plurality of linear slit-shaped openings are formed in the front portion and the rear portion of the container portion in the horizontal direction at predetermined intervals. Further, in the medicine supply tool of Patent Document 2, a curved slit-shaped opening extending in a substantially horizontal direction is provided in the front part of the container part (compartment) facing the center side of the toilet bowl in a state of being hung on the edge of the toilet bowl. .. A plurality of curved slit-shaped openings are formed at predetermined intervals in the vertical direction. The washing water at the time of water washing flows into the container portion through the opening of the container portion, comes into contact with the medicine contained in the container portion to elute the medicine, and flows out into the toilet bowl from the opening of the container portion. In this way, every time the washing water is flushed during washing, the chemicals in the container are eluted into the washing water and supplied into the toilet bowl, providing the desired functions such as washing, disinfection, deodorization, and aroma imparting. To be done.

JP, 2008-248521, A Japanese Patent Publication No. 2017-526839

In the medicine supply tools of Patent Documents 1 and 2, the flow of washing water easily flows directly into the inside of the container portion from each opening of the container portion during washing, and in the application to a flush toilet of a tornado type or a semi-tornado type, There is a problem.

In a semi-tornado flush toilet, the amount of flush water ejected from each ejection port varies. Therefore, when using the chemical|medical agent supply tool like patent documents 1 and 2 for a semi-tornado type flush toilet bowl, the amount of flush water which flows into the inside of a container part from each opening, and contacts a chemical|medical agent is between parts of a chemical|medical agent. Dispersion, the amount of the drug eluted into the wash water varies between the parts of the drug (elution variation). Then, due to this variation in elution, the degree of consumption of the drug varies from site to site. On the other hand, in order to ensure the desired functions such as cleaning, disinfection, deodorization, and aroma imparting, the concentration of the components of the drug supplied to the toilet bowl during one flush (during flushing) (the water accumulated in the toilet bowl after flushing) It is necessary to increase the drug component concentration of the drug to a certain level or more, but if a part of the drug is greatly consumed or disappears, the drug elution amount decreases as a whole, and the drug component concentration supplied to the toilet bowl becomes insufficient. As a result, the desired function cannot be obtained. Therefore, there is a problem that it is necessary to replace the drug in the container portion with a new drug relatively early, and the usable period of the drug (usable flush frequency) is reduced.

Further, when the chemical supply tool as in Patent Documents 1 and 2 is used in a tornado-type flush toilet, the chemical in the container portion comes into contact with a large amount of flush water flowing horizontally along the inner surface of the toilet bowl. However, there is a problem that the drug is quickly consumed due to excessive elution, and the usable period of the drug (the number of usable flashes) is reduced. Particularly, in the medicine supply tool of Patent Document 2, since the curved slit-shaped openings of the container portion extend in a substantially horizontal direction, the flow of cleaning water in a diagonally downward direction (semi-tornado type) and cleaning in a horizontal direction are performed. A flow of water (tornado type) easily flows into the container from each opening, and the degree of consumption due to excessive elution of the drug is large.

In view of the above-mentioned problems in the prior art, the present invention, in the application to a flush toilet of tornado type or semi-tornado type, there is little variation in dissolution or excess dissolution of the drug in the container portion, and a certain usable period (usable An object is to provide a drug supply tool that can secure the number of flushes.

In order to solve the above-mentioned problems, the present invention is a medicine supply tool which is used by being hung on a rim of a flush toilet, and which contains a solid, semi-solid or gel medicine inside, and a flush water. Has an opening through which the container can pass, and in a state of being hung on the edge of the flush toilet, the container portion having a longitudinal centerline that is oriented horizontally along the inner surface of the flush toilet, wherein the opening is A plurality of openings are formed at predetermined intervals in the direction of the longitudinal centerline, and one of the wall surfaces of each opening facing each other in the direction of the longitudinal centerline is on the side of one of the wall surfaces. Also provided is a medicine supply tool having a projecting wall portion protruding outward.

According to the present invention, in a tornado-type or semi-tornado-type flush toilet bowl, a drug supply device capable of ensuring a certain usable period (usable number of flushes) with little variation or excessive dissolution of the drug in the container portion Can be provided.

For example, the solid drug M is contained in the container 1 while being placed on the pedestal 1c. A portion of the container portion 1 above the opening 1a is closed to the outside. The region where the opening 1a is provided is preferably a lower part of the container part 1, specifically, a region from the lower end of the container part 1 to 1/2 or less of the total height of the container part 1, more preferably 1/3 or less. , And more preferably a region of ¼ or less.

As shown in FIG. 4, in this embodiment, a plurality of openings 1a are formed in the lower portion of the container 1B at predetermined intervals in the direction of the longitudinal centerline L. The plurality of openings 1a are arranged on both sides of the lower portion of the lower container 1B with the longitudinal centerline L interposed therebetween, and the arrangement modes of the openings 1a on both sides are mirror image symmetric with respect to the longitudinal centerline L. Further, as shown in FIG. 2, the center line L1 of the opening 1a in a cross section orthogonal to the longitudinal center line L (passes through the center of the opening 1a in the cross section and is orthogonal to the tangent line or the tangent plane of the outer surface of the lower container 1B). The line) inclines downward from the inside of the container 1 toward the outside.

As shown in Fig. 4(b) {C-C cross section of Fig. 4(a): cross section along the normal plane of the outer surface of the lower container 1B}, the openings 1a face each other in the direction of the longitudinal centerline L. The projecting wall portion 1a2 is provided on one wall surface 1a1 side of the two wall surfaces 1a1 to be formed, or on the wall surface 1a1 side that is the rear side with respect to the X direction in the example shown in FIG. Each of the projecting wall portions 1a2 projects outward from the outer edge of each opening 1a. Usually, the X direction is the direction of the horizontal component of the flush water flow jetted obliquely downward in a semi-tornado flush toilet, or the flush water jetted horizontally in a tornado flush toilet. The direction of flow. The projecting wall portion 1a2 may be in a form of extending so as to cover a part or the whole of the opening 1a from the outside with a space.

The pedestal 1c is configured by alternately arranging two types of pedestal portions 1c1 and 1c2 having different forms along the longitudinal center line L at intervals. The pedestal portion 1c1 has a form in which two girders 1c1a are connected to the base portions 1c1b on both sides, and the inclined surfaces 1c1c are provided on the side portions of the base portions 1c1b on both sides. Each inclined surface 1c1c has an upward slope from the outside to the inside of the lower container 1B, and the lower end in the inclined direction is connected to the opening 1a. The width of each inclined surface 1c1c along the longitudinal centerline L is the same as or larger than the opening 1a. The pedestal portion 1c2 has a U shape as a whole.

The engaging claws 1d are respectively provided at a plurality of positions on both edges along the longitudinal centerline L of the lower opening 1b.

As shown in FIG. 5, the receiving portion 2 is formed in an elongated saucer shape along the longitudinal line L and has a shape that is recessed at a gentle slope from the outer peripheral portion toward the central portion, and the central portion has An elongated opening 2a is provided along the longitudinal centerline L.

As shown in FIGS. 2 and 3, the engaging claw 1d of the lower container 1B penetrates the opening 2a of the receiving portion 2 while elastically deforming, and then elastically restores to engage with the lower surface of the receiving portion 2. In this way, the receiving portion 2 is attached to the lower portion of the container portion 1 (lower container 1B). The receiving portion 2 attached to the lower portion of the container portion 1 extends obliquely upward from the lower portion of the container portion 1 with a gentle inclination so as to project outward with respect to the outer surface of the container portion 1 and is shown in FIG. Thus, the outer peripheral edge reaches a position higher than the upper edge of the opening 1a. Therefore, the opening 1a is in a state of being covered by the receiving portion 2 with the space S therebetween.

As shown in FIG. 1, the base of the hanger 3 penetrates through a slit-shaped insertion hole 1e provided in the container 1 (upper container 1A) so as to be vertically movable, and enters the inside of the container 1. I'm out. The base of the hanging device 3 is provided with an adjusting portion 3a having a large number of irregularities that can be engaged with the peripheral edge of the insertion hole 1e, and the tip of the hanging device 3 engages with the edge of the flush toilet. A hook portion 3b that can be stopped is provided. The base portion of the hanging tool 3 is inserted into the insertion hole 1e of the container portion 1, and the adjusting portion 3a is moved vertically in the insertion hole 1e to adjust the position of the container portion 1 with respect to the hook portion 3b. Then, when the container part 1 is put into the flush toilet and the hook part 3b of the hanging device 3 is locked to the edge of the flush toilet, the medicine supply tool (the container part 1 and the receiving part 2) is suspended by the hanging device 3. In this state, it is placed at a desired position in the flush toilet bowl. In this state, the center line L in the longitudinal direction of the container portion 1 faces the horizontal direction (including the substantially horizontal direction) along the inner surface of the toilet bowl.

Due to the difference between the semi-tornado type {Fig. 7(a)} and the tornado type {Fig. 7(b)} described above, the jetting mode and flow direction of the wash water differ, but as shown in Fig. 4(b), In the chemical supply device according to the embodiment, the direction X of the horizontal component of the flow of wash water (half tornado type) jetted obliquely downward, or the direction of the flow of wash water (tornado type) jetted horizontally. With respect to X, the above-mentioned protruding wall portion 1a2 is provided on each of the wall surfaces 1a1 of the respective openings 1a of the container portion 1 on the side of the wall surface 1a1 which is the rear side. It becomes difficult to directly flow from the inside to the inside of the container part 1. Therefore, in the semi-tornado type flush toilet, the flow of flush water ejected obliquely downward from each ejection port merges with each other until it flows into each opening 1a. Variation in the amount of wash water flowing into the inside of 1 is alleviated. The wash water comes into contact with each part of the medicine relatively evenly, so that the variation in elution of the medicine is reduced and a certain usable period is secured. Further, in a tornado-type flush toilet, a large amount of flush water that swirls horizontally along the inner surface of the toilet becomes difficult to directly contact with the drug contained in the container portion 1, and thus the drug is consumed due to excessive elution. Is suppressed and a certain usable period is secured.

Moreover, in the medicine supply tool of this embodiment, the opening 1a of the container part 1 is provided in the lower part of the container part 1, and the inclined surface 1c1c having an upward slope from the outside to the inside of the container part 1. Is provided inside the container portion 1, the action of making it difficult for the flow of the washing water to directly flow into the inside of the container portion 1 from the opening 1a is enhanced, and the above-described effect is enhanced.

Furthermore, in the medicine supply tool of this embodiment, since the receiving portion 2 is provided on the outer surface side of the container portion 1, as shown in FIG. 6, regardless of the specifications of the flush toilet bowl, the washing water W receives the washing water W. Is temporarily received in the space S between the receiving portion 2 and the outer surface of the container 1, and then flows into the container 1 from the space S through the opening 1a. At that time, the cleaning water W flows into the container portion 1 from the opening 1a so as to rise up the inclined surface 1c1c of the pedestal portion 1c1. Therefore, in the semi-tornado flush toilet, the variation in the amount of wash water W ejected from each ejection port is buffered by the pool of wash water W in the space S and then temporarily stored in the space S. The wash water W flows into the container portion 1 from each opening 1a of the container portion 1 with a uniform amount of water, and evenly contacts each portion of the medicine contained in the container portion 1. In this way, the wash water W is evenly contacted with each part of the medicine, so that the variation in the elution of the medicine is further reduced and a certain usable period is secured. Further, in a tornado-type flush toilet, a large amount of flush water W that horizontally swirls along the inner surface of the toilet does not come into direct contact with the drug contained in the container portion 1, so that excessive elution of the drug occurs. The consumption due to is further suppressed, and a certain usable period is secured.

The wash water W that has flowed into the container portion 1 through the opening 1a and has come into contact with the medicine flows out into the toilet through the lower end opening 1b of the container portion 1 and the opening 2a of the receiving portion 2 together with the elution component of the medicine.

FIG. 8 {corresponding to the CC cross section of FIG. 4(a)} shows the form of the peripheral portion of the opening 1a of the container portion 1 (lower container 1B) according to another embodiment. In this embodiment, the portion of the container portion 1 in which the openings 1a are provided is formed in a step shape having the same number of step portions 1a3 as the openings 1a. Each step portion 1a3 is located on the side of the wall surface 1a1 that is the rear side with respect to the X direction among the wall surfaces 1a1 of the openings 1a that face each other in the direction of the longitudinal centerline L, and the outer edge of each opening 1a. It projects more outward than. Therefore, in this embodiment, each step portion 1a3 serves as a protruding wall portion, and the same operational effect as that of the protruding wall portion 1a2 of the above-described embodiment is obtained.

When applying the chemical supply device according to the above embodiment to a semi-tornado type or tornado type flush toilet bowl, since the amount of wash water entering the inside of the container part 1 from the opening 1a of the container part 1 is small, When the elution amount of M is insufficient, or when the elution property of the drug M to the wash water is low and the elution amount of the drug M is insufficient, for example, in the X direction shown in FIG. 4B or FIG. Of the two wall surfaces 1a1 of each opening 1a of the container portion 1, the above-mentioned protruding wall portion 1a2 or 1a3 may be positioned on the front wall surface 1a1 side. As a result, the amount of wash water that enters the container 1 through the opening 1a of the container 1 increases, and an appropriate amount of the drug M to be eluted can be secured. As a means for locating the projecting wall portion 1a2 or 1a3 in this manner, it is simplest and practical to make the direction of the container portion 1 in the X direction opposite to the direction shown in FIG. 4(b) or FIG. It is a means.
