Description

  The present invention relates to a medicine supply tool attached to a rim portion of a flush toilet.

  Some flush toilets use a swirling flow in which wash water flows on the inner surface of the bowl portion. For example, in the flush toilet of Patent Document 1, as shown in FIG. 15, a recess 103 extending along the rim 102 at the upper end of the bowl 101 is formed on the inner side of the bowl, and provided at the end of the recess 103. The cleaning water W is discharged from the water discharge port 104 along the concave path, and the discharged cleaning water is set as a swirl flow S flowing through the concave path to the inner surface of the bowl portion.

  There has been proposed a medicine supply tool for giving a washing action and a deodorizing fragrance effect to this type of flush toilet. The medicine supply tool is usually used by suspending a container containing a medicine from the rim portion of the toilet bowl into the bowl portion with a hook. For example, as shown in FIG. 16, the drug supply device described in Patent Document 2 stores a high-concentration drug solution in a container 112 that is suspended from a rim portion by a hook 111, and stores the drug solution little by little on the release plate 113. To supply. The medicine supply tool 110 is installed so that a part of the washing water flowing in the concave portion of the bowl part flows on the discharge plate 113, so that the chemical solution is eluted into the washing water every time the washing water flows.

FIG. 17A schematically shows a state in which the medicine supply tool 110 is attached to the rim portion 102 of the flush toilet in FIG. In this installed state, since the medicine supply tool 110 slightly enters the recess 103 and only part of it flows into the discharge plate 113, most of the washing water flows smoothly in the recess 103.

  However, in the medicine supply tool described above, the container has a substantially rectangular parallelepiped shape. As a result, depending on the state of attachment to the rim portion 102, the upper portion of the container 112 may be recessed 103 as shown in FIG. You may get deep inside. If washing water is discharged from the spout in this state, a large amount of washing water collides with the container 112, causing a problem that the washing water is scattered outside the toilet.

  In order to cope with this, as shown in FIG. 17 (c), it is conceivable that the container 112 ′ is increased in thickness so that it does not easily enter the recessed path 103. As shown in d), when the corner portion of the container 112 ′ penetrates deeply into the recess 103, the washing water collides with the corner portion of the container 112 ′, and the washing water also scatters out of the toilet. .

  An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a medicine supply device that does not cause a problem of splashing of washing water due to a collision when used in a swirl type flush toilet.

  In order to achieve the above object, the present invention provides a cleaning water guiding recess extending along the rim portion at the upper end of the bowl portion, and a spout for discharging the cleaning water from the end of the recess along the recess. A medicine supply tool for a flush toilet which uses a swirling flow of discharged wash water to flow to the inner surface of the bowl part through a recess, and contains the medicine and is washed when attached to the rim part A container part that enables elution of the drug by contact with water, and a holding part that is coupled to the container part and can be locked to the rim part, and the container part is provided in the concave path when attached to a toilet. A front part that can face each other and an extension part that extends from the upper end of the front part, and the front part allows entry into the recess while allowing contact with the water flow of the recess in a side view. It has a convex main shape that can be regulated, and the holding portion is coupled to the back surface of the container portion and is And a locking member extending from the upper end portion of the vertical member to the container portion side, and the extension portion is inclined when the container portion is inclined in a direction in which the upper portion approaches the recess. The medicine supply tool is provided to extend from the upper end of the front part to the back side so as to restrict the entry of the upper end of the front part into the concave path in contact with the edge of the concave part. It is.

  A drug supply device according to the present invention includes a container part that contains a drug and allows the drug to be eluted by contact with washing water, and a holding part that is coupled to the container part and can be locked to a rim part of a toilet. Thus, it can be used by being attached to the rim portion of the swirling flush toilet. And the container part which accommodates a medicine is provided with the front part which can be opposite to the above-mentioned crevice at the time of attaching to a toilet bowl, and this front part makes it possible to contact this crevice while making contact with the water flow of a crevice. It has a convex main shape that can restrict entry into the road. Therefore, by this container portion, it is possible to achieve a safe attachment state that avoids collision with discharged water due to deep entry into the recess while allowing elution of the drug by contact with the wash water flowing through the recess. . The holding portion includes a vertical member coupled to the back surface of the container portion and extending in the vertical direction, and a locking member extending from the upper end portion of the vertical member to the container portion side. Thereby, when attaching to the toilet bowl, the vertical member is attached in the vertical direction, so that the front portion faces the concave path of the toilet bowl, and the above-described safe attachment state is obtained. Furthermore, when the container part inclines in the direction which makes an upper part approach the recessed path of a toilet bowl, the extension part with which a container part is equipped contacts the edge of a recessed path, and restrict | limits the entrance into the recessed path of the front part upper end. Thus, it extends from the upper end of the front part to the back side. Therefore, even if the container portion has a sharp shape toward the upper end of the front portion, the upper end of the front portion is prevented from entering deeply into the concave due to the inclination of the container portion, and the above-described safe mounting state is ensured. Is done.

  Therefore, according to the present invention, it is possible to provide a medicine supply device that does not cause a problem of splashing of washing water due to a collision when used in a swirl type flush toilet.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The same or similar parts in the drawings may be denoted by the same reference numerals and description thereof may be omitted.

  1 to 4 show a medicine supply device according to an embodiment of the present invention. FIG. 1 is a perspective view seen from the side of the swirl flow flush toilet facing the concave path, and FIG. 3 is a perspective view, FIG. 3 is a side view ((a) is in a closed state, (b) is in an open state), and FIG. 4 is a front view. This medicine supply tool 1 contains a medicine container 20 that contains medicine and allows the medicine to be eluted by contact with washing water, and a lower part is coupled to the container part 20 and an upper part can be locked to the rim part of the toilet bowl. Part 30. The medicine supply device according to this embodiment is of a type that uses a solid medicine, and the medicine is gradually dissolved from the surface by contact with water.

  The container part 20 is provided with a back part 21, a front part 22, and a side part 23, and has a box shape for containing a solid medicine inside. The front part 22 is formed by a part of a cylinder whose axis is horizontal. In a side view, it has a convex shape that allows contact with the water flow of the concave channel while restricting entry into the concave channel, and allows the washing water of the flush toilet to pass through to contact the drug. In order to be able to make it, it is formed in the grid | lattice form which provided many opening part 22s. The container part 20 further includes an extension part 24 extending in an arc from the upper end of the front part 22 to the rear. The back surface portion 21 extends in a planar shape from the lower end of the front surface portion 22 to the extension portion 24. The side portion 23 has a shape that covers portions surrounded by the back surface portion 21, the front surface portion 22, and the extension portion 24 on both sides of the container portion 20.

  Further, as shown in FIG. 3B, the container portion 20 has a rear portion 20a and a front portion 20b that are joined by a hinge portion 20c, and can be opened and closed forward and backward with the hinge portion 20c as a center. The closed state is maintained by the engagement of the micro hooks 25a and 25b provided in the vicinity of both end portions of the back surface portion 21 and the front surface portion 22, and when opening, these micro hooks are elastically deformed and coupled. Solve.

  The holding part 30 is coupled to the back surface part 21 by a coupling part 31. In this embodiment, the coupling portion 31 includes a block 311 coupled to the upper portion of the back surface portion 21 and a guide 312 having a through hole 320 provided at the rear end of the block and extending in the vertical direction. The holding portion 30 includes a vertical member 33 that is coupled to the back surface of the container portion and extends in the vertical direction, and a locking member 34 that extends from the upper end portion of the vertical member toward the container portion. The locking member 34 is formed in a hook shape including a horizontal member 341 that extends substantially horizontally from the vertical member 33 and a skew member 342 that bends at the tip of the horizontal member and extends obliquely toward the vertical member 33 side. . The vertical member 33 is passed through the through hole of the guide 312 and is held at a position slid with respect to the guide 312. For this purpose, the front surface of the vertical member 33 is provided with a large number of horizontally extending micro-projections extending in the vertical direction, and the guide 312 is provided with a concavo-convex portion that engages with the projections. With this engagement, the vertical member 33 is stopped at the guide 312 at an arbitrary vertical position. The holding part 30 is formed of a plastic material rich in elasticity such as polypropylene and polyethylene, and the vertical member 33 and the locking member 34 are dimensioned to be able to engage with a rim part of a swirling flush toilet. Yes. Therefore, the container part 20 can be attached to the position facing the recessed path of the toilet bowl by setting the vertical member 33 to an appropriate vertical position with respect to the guide 312 and elastically deforming the entire vertical member 33 and engaging the rim part.

  FIG. 5A shows an example of a state in which the medicine supply tool 1 is attached to the rim portion of the flush toilet. Here, the container part 20 is arrange | positioned so that the front part 22 may face the recessed path 103 of a flush toilet bowl, and the upper and lower edges of the toilet wall part surrounding a recessed path are contact | abutting to the front part 22. FIG.

  As shown in the figure, the front part 22 of the container part 20 has a convex shape in side view, abuts against the upper and lower edges of the wall part surrounding the concave path 103, can contact the water flow of the concave path, and The entry into the recess is determined to be limited shallowly. Accordingly, an appropriate arrangement state can be obtained in which the drug can be eluted by contact with the washing water flowing through the concave path and the collision and scattering of the discharged water due to the deep entry into the concave path are avoided.

  The extension portion 24 of the container portion 20 has an upper surface that descends in an arc shape from the upper end of the front portion 22 to the back side, and the lower surface extends substantially horizontally from the upper end of the rear portion 21. The shape and size of the extension part 24 is such that the upper end of the front part 22 enters deeply into the recessed path by contacting the edge of the recessed path 103 when the container part is inclined in a direction in which the upper part approaches the recessed path 103. Decided to regulate doing.

  Therefore, the above-described appropriate arrangement state is also guaranteed when the container part 20 is attached to the rim part 102 so as to be inclined as shown in FIG. 5 (b). The manner in which an appropriate arrangement state is assured in this manner will become more apparent by comparison with FIG. 6 showing the arrangement state in the case where there is no extension in the approximated medicine supply device 1 ′. In FIG. 6A, since the container portion 20 ′ is in an upright state, the container portion 20 ′ does not enter the concave path 103 deeply. However, in FIG. 6B, as a result of the container portion 20 ′ being inclined in the direction in which the upper portion approaches the recessed path 103, the upper end of the container section enters the recessed path 103, and the container section 20 ′ enters deeply into the recessed path 103. is doing. This causes a problem that a large amount of washing water collides with the container 20 'and the washing water is scattered outside the toilet.

  In order to ensure that the extension portion 24 is properly placed when the container portion is inclined, it is desirable that the depth dimension of the extension portion 24 be 5 to 35 mm. This depth dimension refers to a dimension from the upper end of the front portion 22 toward the longitudinal member 33 in a direction perpendicular to the longitudinal member 33 of the holding portion 30. If this dimension is less than the above lower limit value, the distal end of the rear portion of the extension portion 24 enters the recessed path 103 when the container portion is inclined, and the entry restricting action cannot be sufficiently exhibited. On the other hand, if this dimension exceeds the above upper limit value, the extension part 24 will protrude greatly into the bowl of the toilet bowl, which will impair the aesthetics or be susceptible to contamination by excrement.

As shown in FIGS. 3 and 4, the dimensions of each part of the medicine supply tool are as follows.
-Height H of the container part 20: 50 mm
-Width W of container part 20: 100 mm
-Depth D1 of container part 20: 42.5 mm
-Depth D2 of extension 24: 17mm
-Curvature radius R of the arcuate surface of the container front portion 22: 25 mm
-Length of holding part 30 (vertical member 33 + locking member 34): 150 mm
If the front portion is appropriately arranged with respect to the concave path by appropriately restricting the entry into the concave path while allowing contact with the water flow of the concave path, a side view as in the above embodiment. It need not be arcuate. Moreover, it is not necessary to have a smooth convex shape in a side view, and any convex shape can be used as long as the above-described appropriate arrangement can be obtained even if unevenness and corners are mixed. For example, the front portion 22 may include an angular uneven portion as shown in FIG. 7A or a wavy uneven portion as shown in FIG. 7B in a cross section perpendicular to the front portion 22. In the present specification and claims, such an overall convex shape of the front portion is referred to as a convex main shape.

Next, a desirable mode for ensuring proper arrangement with respect to the above-described concave path will be described with reference to FIG. In this embodiment, as shown in the figure, the front portion 22 and the extension portion 24 have a gap viewed in a vertical cross section perpendicular to the plane P when applied to the gap C formed with a width of 30 mm with respect to the plane P. The area S of the entry part from C is used as a reference (in the figure, for the sake of easy understanding, a plane P extending in the vertical direction and a gap C formed horizontally with respect to the plane P at a vertical interval of 30 mm are shown. ing). The shape can be determined such that the area S is 140 mm ² or less. FIG. 8A shows an ideal attachment state, that is, a state in which the medicine supply tool is positioned with the vertical member 33 of the holding unit 30 in the vertical direction. Depending on the user, the medicine supply tool may be tilted and attached as long as the holder 30 is deformed. Even in such a case, it is desirable that the proper arrangement with respect to the concave path is ensured. In this regard, FIG. 8B shows a state in which the medicine supply tool is attached with a large inclination. Also in this case, it is desirable to determine the shapes of the front portion 22 and the extension portion 24 so that the entry area S is in the above range.

If the area S of the entry portion exceeds the above range, the amount of water that comes into contact with the container portion increases, and the problem that the wash water scatters out of the toilet is likely to occur. From this viewpoint, it is more desirable that the area of the entry portion is 100 mm ² or less. As can be understood from the fact that the holding part 30 is greatly deformed in FIG. 8B, the inclination of the medicine supply tool at the time of attachment is regulated to some extent by the deformation resistance of the holding part 30.

Further, as in the example shown in the figure, for the structure in which the front portion 22 comes into contact with the cleaning water in the concave path and is taken into the container, the front portion 22 is recessed to some extent for contact with the cleaning water. Must enter the road. In order to ensure the entry, when the front portion 22 is applied to the gap C provided in the plane P in the same manner as described above, the entry from the gap C viewed in a vertical cross section perpendicular to the plane P. It is desirable to determine the shape of the front portion so that the area S of the portion is 25 mm ² or more.

  As shown in a plan view of the medicine supply tool in FIG. 13, the front portion 22 includes a protruding piece 22t that protrudes to the front surface in the vicinity of the opening 22s, and the protruding piece 22t allows a part of the flow W of washing water to be provided. It is also possible to adopt a form leading to the opening 22s. In this case, as indicated by hatching in FIG. 14, it is desirable to determine the shape of the front portion 22 so that the area S of the entry portion from the gap C including the projecting piece 22t becomes the above-mentioned value.

  The amount of entry of the container part with respect to the concave path varies depending not only on the container part but also on the shape and dimensions of the concave path. However, the commercially available swirl type flush toilet bowl is designed so that the speed and amount of the washing water flowing in the concave path are appropriate, so that the difference in the shape and size of the concave path is limited. Therefore, by using the plane gap C in consideration of the cross-sectional shape and dimensions of a typical concave channel as a reference, it is possible to appropriately arrange the container portion with respect to the concave channel of many general swirl type flush toilets.

  In this way, an appropriate arrangement with respect to the concave path can be obtained for the upper end portion and the front portion of the container portion. On the other hand, in the normal attachment mode, the attachment is not performed so that the holding portion 30 is moved away from the rim portion of the toilet bowl, so that it is difficult to perform the attachment so that the container portion enters deeply into the recess from the lower end side. However, if the height and thickness (depth dimension) of the container part are reduced, the possibility is low, but for example, as shown in FIG. 9, the container part may be deeply inserted into the concave path from the lower end side. .

  On the other hand, the desirable form for further ensuring the proper arrangement of the container part is the height H of the front part in the direction along the vertical member of the holding part, and it is held through the upper end of the front part in the cross section orthogonal to the front part. The distance D from the straight line extending in parallel to the vertical member of the part to the lower end of the front part can be specified as a reference. FIG. 10 shows the height H and the distance D. FIG. 10 (a) shows a flat container portion 20 in which the back portion 21 is parallel to the vertical member 33, and FIG. 10 (b) shows a non-flat back portion 21 ( Here, the case of the container portion 20 having a convex shape rearward is shown. In FIG. 10, the position of height H and the distance D is shown in the container part 20 shown with the continuous line, and the broken line has shown the case where the distance D is 0 (zero).

  A desirable height H of the front portion 22 for proper placement is 30 to 70 mm, and a distance D is D ≦ 20 mm when 30 mm ≦ H <40 mm, and D ≦ 40 mm when 40 mm ≦ H ≦ 70 mm. is there.

  In the above, if the height H is lower than 30 mm, the container part can easily enter the concave path from the lower end side if the holding part is slightly separated from the rim part of the toilet bowl. Further, if the height H is higher than 70 mm, it will extend greatly downward in the toilet bowl, so it will be easily contaminated with excrement. Further, when 30 mm ≦ H <40 mm, if the distance D exceeds 20 mm, the lower end of the front portion protrudes forward, and it is easy to enter the concave path. This ease of entry decreases as the height of the front portion increases. When 40 mm ≦ H ≦ 70 mm, there is no problem until the distance D is 40 mm. It becomes easy to enter.

  Next, the desirable form for performing the proper arrangement | positioning with respect to a concave path more reliably is demonstrated about the case where a front part has an arc-shaped surface of the circular arc shape or the shape approximated to the circular arc in the longitudinal cross section. Referring to FIG. 7 as an example, the arcuate surface of the container portion including the front portion 22 has a vertical section perpendicular to the front portion, and is a curve that falls between the following arc having a radius of curvature R and a concentric arc having a larger radius ΔR. And is preferably in the range of the following central angle Q.

15 mm ≦ R ≦ 35 mm [Formula 1]
ΔR = (R / 2) −7 (mm) [Formula 2]
The central angle Q is
When 15 mm ≦ R <20 mm, 180 degrees or more When 20 mm ≦ R <30 mm, (3600 / R) degrees or more When 30 mm ≦ R ≦ 35 mm, 120 degrees or more.

  The central angle Q can be set to 360 degrees because of the structure, but if it becomes too large, the container part will overhang into the bowl of the toilet bowl, which may impair aesthetics or be easily contaminated by excrement. In view of this, it is desirable to determine the upper limit of the central angle Q. From this point of view, the central angle Q is desirably 270 degrees or less, and more desirably 240 degrees or less.

Even when the shape of the container part is determined in this way, the convex main shape of the arcuate surface including the front part may include the wavy uneven part described above with reference to FIG. The above-described specification of the radius of curvature is based on the following reason.
(i) When the radius of curvature of the arcuate surface is small, the convex shape becomes strong, and it is easy to enter deeply into the concave road when attached to the toilet. When the radius of curvature is large, the convex shape becomes gentle and the concave shape is entered. The degree becomes too shallow, and the contact of the container part with the water flow in the concave path becomes insufficient, and the drug elution amount may not be sufficiently obtained. From this point of view, the amount of entry into the concave road is made appropriate by setting the radius of curvature of the arcuate surface within a predetermined range.
(ii) When the arcuate surface includes an uneven portion, the allowable range ΔR becomes wider as the radius of curvature of the arcuate surface increases. That is, when the radius of curvature is small, the arc-shaped surface penetrates deeply into the concave path, so that the allowable range of the uneven portion is small. When the radius of curvature is large, the allowable range of the uneven portion is large because the arc-shaped surface enters shallowly into the concave path.
(iii) In order to avoid excessive entry into the concave path, it is necessary for the arcuate surface to have a certain height, and for this purpose, it is necessary to increase the central angle Q when the radius of curvature is small. When the radius of curvature is large, the central angle Q may be small.
(iv) By setting within the range shown in the above formulas 1 and 2, appropriate arrangement with respect to the concave path can be reliably performed.
(v) Even in the above range, when the container is tilted around the horizontal axis so that the lower end or upper end of the container part faces the recess when attached to the toilet, the upper end part of the extension part or the lower end part of the front part Although there is a possibility that the portion will enter deeply into the concave path, it is more reliably prevented by setting the central angle Q of the arc to 210 degrees or more. On the other hand, if the central angle Q is too large, an extra portion is formed in the container portion, so it is desirable that the angle be 270 degrees or less.

  The medicine supply device may be of a type (or a solid medicine / liquid medicine common type) containing the liquid medicine shown in FIG. In this medicine supply tool, the container portion 20 ″ has a casing 20c for containing the medicine, a discharge plate 26 provided at the lower portion of the casing 20c, and a liquid introduction section for supplying the medicine from the casing 20c to the discharge plate 26 little by little. The casing 20c has a shape close to the container part 20 shown in Fig. 1 to Fig. 4, but the upper part of the front surface 220 is an arcuate surface convex in side view, and the lower part is rearward. The discharge plate 26 is located below the recessed portion, and the liquid introduction portion 25 is provided between the casing 20c and the discharge plate 26 along the back surface portion 21a of the casing 20c. .

  When attaching the medicine supply tool to the toilet bowl, it is desirable to keep the posture of FIG. 11 (a) and attach it to the rim part 102 of the toilet bowl so that the vertical member 33 of the holding part 30 is vertical. On the other hand, as shown in FIG. 11 (b), even when the medicine supply tool is inclined during the installation, the front surface 220 of the casing 20c is the upper edge of the concave wall, and the front end portion 26a of the discharge plate 26 is the concave wall. Contact the lower edge. Further, when the container part 20 ″ is inclined in a direction in which the upper part approaches the concave path, the extension part 24 comes into contact with the upper edge of the concave wall. Thus, in this medicine supply tool, the front surface 220 of the casing 20c and The front end portion 26a of the discharge plate 26 forms a front portion 22a that can face the concave path when attached to the toilet. The holding portion 30 coupled to the container portion 20 ″ is shown in FIGS. It is comprised similarly to embodiment shown in (1).

  In use, a portion of the water flowing in the recess 103 of the toilet bowl flows into the discharge plate 26 and flows into the bowl with the drug staying there. The medicine supply tool 1 shown in FIG. 11 is also similar to the previous embodiment with respect to an appropriate arrangement in which the medicine supply tool 1 abuts against the wall of the concave path to allow contact with the water flow of the concave path and does not enter deeply into the concave path. Realize the state.

  In the embodiment of FIG. 11, since the front portion 22a is formed by the front surface 220 of the casing 20c and the front end portion 26a of the discharge plate 26, the longitudinal sectional area of the portion entering the gap provided in the plane is performed together with FIG. 7 and the explanation given with reference to FIG. 7 for the arcuate surface applies to the curved surface formed by connecting the front surface 220 and the discharge plate front end portion 26a. Fig. 12 shows an approaching state from the gap C as seen in a longitudinal section perpendicular to the plane P, with respect to the container portion 20 "which is applied to the gap C with respect to the plane P. (a) of Fig. 12 shows This is a case where the vertical member 33 of the holding portion 30 is vertical, and (b) shows a state where the container portion 20 ″ is inclined and the front portion 22a has entered the gap C most deeply. Also in this embodiment, as shown in FIG. 12B, it is desirable to determine the shapes of the front portion 22a and the extension portion 24 so that the area S is in the above-described range when the degree of entry is maximized.

In the case where the drug is brought into contact with the washing water flowing through the lower discharge plate 26 like the container portion 20 ″, the tip of the discharge plate 26 does not enter the concave path 103 but is recessed. By contacting the bowl wall under the path, the wash water flowing down can be received by the discharge plate 26. Therefore, in this case, the front portion 22a does not have to enter the concave path 103, and the above-mentioned In this case, the area S of the entrance portion of the front portion 22a and the extension 24 from the gap C is 0. Therefore, in the case of such a medicine supply device with a release plate, entry area S is in the range of 0～140Mm ² is preferably, will be more desirable is a 0 to 100 mM ^2.

  The present invention is not limited to the above embodiment, and various modifications can be made. It is not always necessary to provide the coupling portion shown in the above embodiment at the coupling portion between the holding portion and the container portion, and the guide or the holding portion can be directly coupled to the container portion. The container portion may contain a drug and have various shapes of pores or those having pores formed by a mesh wall so that the drug can be eluted by contact with washing water. it can. The pores can be provided on the entire surface or a part of both the front portion and the side portion of the casing or the front portion. The extension portion does not need to be provided over the entire width of the container portion. For example, the extension portion may be provided on a part of the container portion, such as both ends of the container portion as indicated by a one-dot chain line and a reference numeral 24a in FIG. .
