Description

  The present invention relates to a chemical liquid supply apparatus that is attached to a rim of a toilet bowl and supplies a chemical liquid for cleaning the toilet bowl.

  Various chemical solution supply apparatuses for cleaning toilet bowls and obtaining an aroma effect have been proposed depending on the type of toilet bowl to be attached. For example, for a type having a water storage tank, a chemical liquid supply device has been proposed that is arranged in the hand washing section at the top of the tank, and this apparatus supplies chemical liquid into the water storage tank along with water supplied to the hand washing section. Is configured to do.

On the other hand, toilet bowls that do not have a hand-washing section at the top of the tank or that do not have a water storage tank itself are also on the market. For this purpose, a chemical supply device that is directly attached to the toilet rim has been proposed. For example, the chemical solution supply device described in Patent Document 1 is provided with a chemical solution bottle so as to be hung on a rim of a toilet bowl, and a plate for receiving the chemical solution is attached below the bottle. And a chemical | medical solution is supplied to the inner wall face of a toilet bowl by exposing the chemical | medical solution supplied on a plate from a chemical | medical solution bottle by running water. As a result, the toilet bowl is washed, and the fragrance effect can be obtained by the fragrance contained in the chemical solution.

  By the way, the chemical solution supply device is configured such that the chemical solution discharged from the chemical solution container flows down directly onto the plate through the discharge hole, and the chemical solution spreads along a groove formed on the plate. Yes. However, since the chemical | medical solution used for toilet bowl washing | cleaning generally has high viscosity, it is necessary to design a groove | channel according to viscosity. Therefore, if the width, depth, and shape of the groove are not optimized in accordance with the chemical solution to be used, it is difficult for the chemical solution to flow and spread on the plate. Thus, the design of the groove is not easy, and has been a problem in producing this type of chemical solution supply apparatus.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a chemical solution supply apparatus capable of dispersing a chemical solution with a simple structure.

  The present invention is a chemical solution supply device attached to a toilet rim, which is made to solve the above-described problem, contains a chemical solution, has a chemical solution discharge port, and the discharge port. A chemical solution discharge mechanism connected to guide the chemical solution in the chemical solution container to the outside; a support member that supports the chemical solution discharged from the chemical solution discharge mechanism in contact with running water flowing in the toilet; the chemical solution container; A discharge mechanism, and a suspension member for hanging the support member on a rim of a toilet bowl, the chemical solution discharge mechanism is supplied with an outflow hole for discharging the chemical solution, and a chemical solution discharged from the outflow hole, And at least one ridge that protrudes toward the support member and extends in the surface direction of the support member.

  According to this configuration, since the chemical liquid discharged from the outflow hole is configured to be supplied to at least one ridge extending in the surface direction of the support member, the chemical liquid is supported along the ridge. It spreads in the surface direction of the member. Therefore, unlike the conventional example, it is not necessary to precisely design the width and depth of the groove, and the chemical solution path can be formed simply by arranging the protrusions. Can be widely distributed. In addition, it is preferable to provide an appropriate inclination at the base for flowing the chemical solution. To provide such an inclination, the design of the entire apparatus must be considered. If the chemical liquid is caused to flow by the portion, for example, an inclination can be provided only in the ridge portion, and in this way, the flow of the chemical liquid can be easily formed. As a result, the design is simplified.

  Furthermore, in the configuration in which the chemical is spread by a groove formed in the base after dropping the chemical from the outflow hole to the base as in the conventional example, the space between the base and the outflow hole depends on the viscosity of the chemical. If it is not spread to some extent, the chemical solution may be stagnant and difficult to flow. Therefore, there is a restriction on design, and there is a possibility that the apparatus becomes large. On the other hand, if the chemical solution discharged from the outflow hole is transmitted through the protrusion as in the present invention, the chemical solution can be expanded regardless of the distance between the outflow hole and the base portion. The “protrusion” refers to a member that extends in the surface direction of the support member, is formed in a plate shape, a rod shape, or the like and protrudes.

  The protrusions can have various configurations. For example, two or more protrusions can be provided, and each protrusion can be configured to extend radially around the outflow hole. If comprised in this way, a chemical | medical solution can be spread further widely. In addition, the radial shape here does not need to extend the ridge portion in all directions of 360 °, and the ridge portion is arranged over a part thereof, particularly, a predetermined angle facing the rim side. That's fine.

  In addition, a chemical | medical solution does not necessarily need to be supplied on a supporting member, and can be made to expose | bleach to running water, with the protrusion part hold | maintained. Or it can be made to protrude so that a protruding part may approach a support member, as it leaves | separates from an outflow hole. By carrying out like this, the chemical | medical solution on a protrusion part can be smoothly supplied to a supporting member. Thus, by supplying a chemical | medical solution on a support member, a chemical | medical solution can be efficiently supplied to a toilet bowl with a flowing water.

  Further, at least one through hole facing the outside can be formed in the support member. According to this structure, the flowing water which flowed on the support member can be flowed out of the apparatus through the through hole. Therefore, even if the momentum of the flowing water is strong, a part of the flowing water flows out to the outside through the through hole, so that the momentum of the flowing water on the support member can be dispersed. As a result, it is possible to prevent the flowing water from entering the chemical container through the outflow hole.

  At this time, it is preferable that the through hole is formed at a position facing the outflow hole or in the vicinity thereof, and the protruding portion extends so as to cross the through hole. By doing so, the chemical liquid discharged from the outflow hole passes through the protruding portion and passes through the through hole, so that it can be prevented from being directly supplied into the through hole, and the chemical liquid is supplied to the rim side. Can carry.

  Further, the through hole may not be disposed directly below the outflow hole, and may be formed at any position facing the protruding portion. In this case, it is preferable that the ridge portion crosses the upper part of the through hole and extends outward from its peripheral edge.

  The through-holes can be arranged in various ways. For example, at least one through-hole can be arranged on the rim side and the opposite side across the outflow hole.

  Alternatively, it can be arranged in a region opposite to the rim across the outflow hole.

  The present invention is a chemical solution supply device attached to a toilet rim, containing a chemical solution, having a chemical solution discharge port, connected to the discharge port, the chemical solution in the chemical solution container to the outside A guiding liquid discharge mechanism, a support member for supporting the chemical liquid discharged from the chemical discharge mechanism so as to be in contact with running water flowing in the toilet, and the liquid container, the drug discharging mechanism, and the support member are suspended from a rim of the toilet bowl. A suspension member for hanging, and the support member has at least one through hole facing the outside, and the chemical solution discharging mechanism is discharged from the outflow hole for discharging the chemical solution and the outflow hole. At least one projecting portion that is supplied with a chemical solution and projects toward the support member, and at least a part of the projecting portion is disposed at a position facing the region where the through hole is not formed in the support member. It is.

  According to this configuration, since the through hole is formed in the support member, the flowing water that has flowed onto the support member flows out of the apparatus through the through hole. Therefore, even if the momentum of the flowing water is strong, a part of the flowing water flows out to the outside through the through hole, so that the momentum of the flowing water on the support member can be dispersed. As a result, it is possible to prevent the flowing water from entering the chemical container through the outflow hole. It should be noted that at least a part of the protruding portion protruding from the chemical solution discharging mechanism toward the support member is at a position facing a region where the through hole is not formed. Therefore, the chemical liquid that falls to the support member side via the protruding portion does not flow from the through hole to the outside but is supplied onto the support member. Thereby, a chemical | medical solution can be reliably exposed with flowing water.

  All of the protrusions can be arranged on a region where the through hole is not formed, or a part thereof can be arranged on the through hole. When a part is arranged on the through-hole, that is, when at least one through-hole is formed at a position facing the protrusion in the support member, the protrusion crosses over the through-hole and passes through the through-hole. It can arrange | position so that it may extend outside rather than the periphery of a hole.

  Here, when a part of protrusion part exists on a through-hole, there exist the following advantages. That is, even if the chemical solution is supplied onto the support member, the chemical solution may solidify on the support member if there is no running water for a long time. In this case, as described above, when a part of the projecting portion is on the through hole, the chemical solution can flow out of the support member through the through hole. As a result, it is possible to prevent the chemical liquid from collecting on the support member and solidifying.

  There are various ways of arranging the through holes. For example, when a plurality of through holes are formed, each through hole can be arranged at least one on each of the rim side and the opposite side across the protruding portion. Or it can also arrange | position in the area | region on the opposite side to a rim on both sides of a protrusion part. Such a through hole on the side away from the rim can discharge the chemical solution from the through hole to the outside, for example, when the support member is attached to the rim so as to incline downward as it moves away from the rim. It is possible to prevent accumulation in the apparatus.

  The protruding portion can be in various forms, and can be arranged only in the vicinity of the outflow hole, or can be arranged so as to extend in the surface direction of the support member. In particular, when a plurality of projecting portions are provided and extend radially in the surface direction of the support member, the chemical solution is transmitted through the projecting portions, so that the chemical solution can be supplied over a wide range on the support member.

  According to the chemical solution supply apparatus according to the present invention, the chemical solution can be efficiently dispersed.

(First embodiment)
Hereinafter, a first embodiment of a chemical solution supply apparatus according to the present invention will be described with reference to the drawings. 1 is a perspective view of a chemical liquid supply apparatus according to the present embodiment, FIG. 2 is a cross-sectional view of FIG. 1, FIG. 3 is a cross-sectional view of FIG. 1 along the AA line of FIG. FIG. 5 is an exploded perspective view of FIG.

  This chemical solution supply device is used by being hung on a toilet rim, and as shown in FIGS. 1 to 5, a chemical solution container 1 containing a chemical solution, and an apparatus main body 2 for supporting this from below. And a suspension member 3 for hanging the device on the rim. In addition, a chemical liquid discharge mechanism 4 that supplies the chemical liquid flowing out from the chemical liquid container 1 to the bottom surface of the apparatus main body 2 is disposed inside the apparatus main body 2. Hereafter, each member mentioned above is demonstrated in detail.

  As shown in FIG. 5, the chemical solution container 1 is formed in a transparent dome shape and has a discharge port 11 on the lower surface. A cap 13 is attached to the discharge port 11. The cap 13 is composed of an annular main body 131 and a thin film portion 132 that closes the central hole. When used, the cap 13 breaks the thin film portion 132 to discharge the chemical solution.

  As shown in FIGS. 4 and 5, the apparatus main body 2 includes a support plate (support member) 21 constituting a bottom surface and a wall body 22 surrounding the periphery thereof. The support plate 21 includes a base portion 211 having a substantially rectangular shape in plan view and a movable portion 212 that is swingably connected to one side thereof. The support plate 21 has three sides other than the side on which the movable portion 212 is provided. The wall body 22 described above is provided in a U-shape. Therefore, the apparatus main body 2 is formed in a cup shape in which a wall on one side is notched and opened, and a part of the base portion 211 and the movable portion 212 are configured to protrude from the open portion 23. Then, as will be described later, running water flows into the apparatus main body 2 from the open portion 23.

  Moreover, the support | pillar 24 extended upwards is attached to the center of the base 211, and the suspension member 3 is attached to the space between this support | pillar 24 and the cover member 411 mentioned later so that an up-down movement is possible. The hanging member 3 is formed in a band shape that is bent at two locations so as to be elastically deformable. In an initial state, the hanging member 3 is folded as shown in FIG. Further, since the hanging member 3 is configured to be movable up and down, the height of the chemical solution container 1 and the apparatus main body 2 with respect to the rim can be adjusted so that the apparatus and the rim do not interfere with each other.

  Next, the support plate 21 will be described in more detail. As shown in FIG. 2, in the support plate 21 of this embodiment, the base 211 and the movable part 212 are integrally formed of resin or the like, and the base 211 is about 6 degrees toward the movable part 212 side. Inclined downward. As a result, as will be described later, the discharged chemical liquid can easily flow to the rim side. The inclination angle α of the base 211 can be set to other than this, and can be set to, for example, 0 to 45 degrees, and preferably 3 to 30 degrees.

  A groove 213 is formed on the back surface of the support plate 21 along the boundary line between the base portion 211 and the movable portion 212. Therefore, since the boundary between the base 211 and the movable portion 212 is formed into a thin film shape by the groove 213, the movable portion 212 can swing with respect to the base 211. Further, since the groove 213 is formed on the back surface of the support plate 21, when the movable portion 212 is inclined downward, the opposing side wall surfaces in the groove 213 come into contact with each other, thereby restricting the downward inclination. (FIG. 2A). On the other hand, it is possible to tilt upward, and if a force is applied, the movable portion 212 can be swung upward. However, upward inclination is also regulated as follows. As shown in FIG. 1 and FIG. 2, a substantially rectangular side plate 214 is attached to both sides of the base portion 211, and an end surface extending vertically toward the movable portion 212 side of this side plate 214 is connected to the movable portion 212. Contact is possible. That is, when the movable portion 212 is inclined to an inclination angle β of 90 degrees or more, the end surface of the side plate 214 and the movable portion 212 come into contact with each other, and the movable portion 212 is not inclined further (FIG. 2). (B)). In the initial state, the movable portion 212 is inclined upward at an inclination angle β of about 30 ° with respect to the base portion 211. From this state, the movable portion 212 is about 0 to 90 ° with respect to the base portion 211 due to elastic deformation of the boundary portion. Inclination is possible within a certain range. In the apparatus main body 2 configured as described above, a plurality of water holes 25 are formed in the peripheral edge of the base portion 211 and the wall body 22, and the water flowing in from the open portion 23 passes through these water holes 25 to form the apparatus. It is discharged from the main body 2 (see FIGS. 1 and 5).

  Next, the chemical liquid discharge mechanism 4 will be described. 2-5, the chemical | medical solution discharge | emission mechanism 4 is arrange | positioned between the chemical | medical solution container 1 and the support plate 21, the upper member 41 arrange | positioned at the upper side, and the lower member arrange | positioned at the lower side 42. The upper member 41 is formed in an elliptical cylindrical shape in plan view, and the lower part is open. On the other hand, the lower member 42 includes a plate-like portion 421 having an elliptical shape in plan view, and a low wall member 423 formed so as to extend in the vertical direction around the lower portion 42 so as to block the lower opening of the upper member 41. Placed in. And the buffer space 43 which hold | maintains a chemical | medical solution is formed between both by combining the upper member 41 and the lower member 42. Hereinafter, the upper member 41 and the lower member 42 will be described in more detail.

  As shown in FIGS. 2 and 5, a rail-like cover member 411 extending upward is attached to the side surface of the upper member 41. As described above, the cover member 411 abuts on the support column 24 and is suspended. A space for accommodating the hanging member 3 is formed. The upper member 41 is provided with a sharp cylindrical communication pipe 412 with a sharply cut end at the center of the upper surface, and a total of four air circulation holes 413 at the end of the upper surface. . The communication pipe 412 is pierced by the cap 13 of the chemical solution container 1 described above and plays a role of breaking the thin film portion 132. Further, an annular groove 417 is formed on the periphery of the communication pipe 412, and the main body 131 of the cap 13 is fitted into the groove 417. On the other hand, as shown in FIG. 2, a cylindrical fixed pipe 414 extending toward the lower member 42 and a plurality of chemical liquid communication holes 415 disposed in the vicinity thereof are formed on the inner bottom surface of the communication pipe 412. . The chemical solution communication holes 415 and the air circulation holes 413 described above communicate with the buffer space 43.

  Next, the lower member 42 will be described with reference to FIGS. 6 is a perspective view (a), a plan view (b), a front view (c), and a bottom view (d) as seen from the lower surface of the lower member, and FIG. 7 is a partial perspective view (a) of the lower member. It is the BB sectional view (b). First, as shown in FIG. 5, at the center of the lower member 42, a cylindrical guide tube 424 fitted to the fixed tube 414 of the upper member 41, and a circular fixed wall 425 provided so as to surround the periphery thereof. And are provided. The above-described fixed tube 414 is fitted into the gap between the guide tube 424 and the fixed wall 425. The upper opening of the guide tube 424 has an obliquely cut shape, and a guide groove 426 extending in the vertical direction along the outer peripheral surface of the guide tube 424 is formed from the lower side of the opening. Here, as shown in FIGS. 6 and 7, since the guide tube 424 is fitted inside the fixed tube 414, a chemical solution passage (guide channel) is formed by the inner wall surface of the fixed tube 414 and the guide groove 426. Is done. A space through which the chemical solution passes is also formed in the gap between the bottom surface of the gap between the guide tube 424 and the fixed wall 425 and the lower end portion of the fixed tube 414. More specifically, at the bottom surface of the gap, about 90 degrees on both sides of the guide groove 426 constitutes an extension path 427 for the chemical solution, and on the opposite side to the guide groove 426, a half of about 180 degrees is formed. A circular outflow hole 428 is formed. And the chemical | medical solution which passed the extension path 427 flows out from the outflow hole 428 to the support plate 21 side.

  As shown in FIG. 6, a pair of leg portions 429 are attached to both ends of the lower surface of the wall member 423 in the lower member 42, and the leg portions 429 provide a space between the lower surface of the lower member 42 and the support plate 21. A space is formed. As will be described later, this space serves as a path for chemicals and running water. Further, on the lower surface of the lower member 42, a protruding piece 431 that connects both ends of the above-described outflow hole 428 and a pair of protrusions 432 that extend from both ends of the protruding piece 431 are formed. Each protrusion 432 extends obliquely toward the movable portion 212 so as to be separated from each other, and as shown in FIG. 6C, the protrusion height from the lower surface of the lower member 42 increases toward the tip. Is getting bigger. That is, as shown in FIG. 2, each protrusion 432 has a smaller gap with the support plate 21 as it goes to the tip, and is in contact with the support plate 21 at the tip.

  Next, a method of using the chemical supply apparatus configured as described above will be described with reference to FIG. FIG. 8 is a side view showing an attached state of the chemical solution supply apparatus. First, the chemical solution container 1 is disposed on the upper member 41. Thereby, the communication pipe 412 is pierced into the cap 13 of the chemical solution container 1 and the chemical solution container 1 is fixed. Subsequently, when the device is attached to the toilet rim, the suspension member 3 is pushed out from the state of FIG. And as shown to Fig.8 (a), it arrange | positions so that the rim | limb R may be pinched | interposed. At this time, the movable portion 212 abuts on the inner wall surface of the toilet bowl, but can be swung with respect to the base portion 211, and therefore tilts according to the distance between the base portion 211 and the toilet inner wall surface S. That is, as shown in FIG. 8A, when the distance between the base 211 and the toilet inner wall surface S is small, the movable portion 212 is largely inclined while being pressed against the toilet inner wall surface S, and the clearance between the toilet inner wall surface S and Fill. On the other hand, when the distance is large, the inclination angle β is small as shown in FIG. 8B, but in any case, the gap between the base portion 211 and the toilet inner wall surface S is filled. As a result, since the chemical liquid that has flowed out to the base portion 211 can be efficiently swept away and flowed to the toilet bowl, an excellent cleaning effect can be obtained regardless of the shape of the toilet bowl.

  Subsequently, the flow of the chemical solution will be described. When the thin film portion 132 of the cap 13 is broken by the communication pipe 412, the chemical solution flows out from the chemical solution container 1 to the chemical solution discharge mechanism 4, and a part thereof is in the buffer space 43 via the communication tube 412 and the chemical solution communication hole 415. Flow into. On the other hand, as shown in FIGS. 6 and 7, the remaining chemical liquid flows downward through the guide groove 426 and then flows out to the lower surface side of the lower member 42 through the extension path 427 and the outflow hole 428. And this chemical | medical solution moves to the movable part 212 side along the protrusion 431 and the protrusion part 432, and moves to the support plate 21 in the contact part of the support plate 21 and the protrusion part 432. FIG.

  Here, the function of the buffer space 43 described above will be described. The buffer space 43 functions as a buffer when a pressure change occurs in the chemical liquid container 1 due to a temperature change. For example, when the temperature rises and the chemical solution container 1 is warmed, the air in the container 1 expands and the inside of the container 1 becomes positive pressure. In this case, the chemical solution in the chemical solution container 1 is pushed out and discharged. However, since this chemical solution flows into the buffer space 43 through the chemical solution communication hole 415 in addition to the guide groove 426, the chemical solution is excessive from the guide groove 426. Is prevented from being leaked into the water. On the other hand, when the temperature of the chemical liquid container 1 is lowered by being cooled by flowing water and the air in the chemical liquid container 1 is contracted to become negative pressure, the pressure of the air acts on the chemical liquid through the air circulation holes 413. The buffer space 43 is sucked into the chemical liquid container 1 through the chemical liquid communication hole 415. As a result, it is possible to prevent the water that has flowed into the apparatus main body from being sucked into the chemical container and discharged. In this way, the buffer space 43 is in the container 1 because most of the chemical liquid flows between the chemical liquid container 1 and the buffer space 43 even when a pressure change occurs in the chemical liquid container 1 due to a temperature change. It is possible to prevent the chemical solution from flowing out excessively or restricting outflow.

  After the apparatus is installed as described above, when water is flowed into the toilet, the flowed water travels along the toilet inner wall surface S from the inside of the rim R as shown in FIG. Guided to the 211 side (arrow X). Then, the chemical solution stored at the boundary portion between the base portion 211 and the movable portion 212 is swept away while flowing out from the water flow hole 25 or bounced back against the wall body 22 in the device, and from the open portion 23 to the outside of the device. To flow. Thus, the chemical solution is supplied to the toilet inner wall surface S together with running water, and the toilet bowl is cleaned. In addition, although the water which flows on the support plate 21 may flow backward in the chemical solution supply mechanism 4 and enter the chemical solution container 1, this is dealt with as follows. That is, in the apparatus according to the present embodiment, the chemical liquid flows out onto the support plate 21 via the guide groove 426 and the extension path 427. In particular, since the extension path 427 extends horizontally, the water that has flowed upward through the protrusions 431 and the protrusions 432 once passes through the extension path 427 extending horizontally, and then extends further vertically. If it does not pass through, the chemical solution container 1 is not reached. Thus, in this apparatus, since the path | route extended horizontally is arrange | positioned in the path | route of the orthogonal | vertical direction from the support plate 21 to the chemical | medical solution container 1, entry of water can be prevented.

  As described above, according to the present embodiment, the chemical liquid discharged from the outflow hole 428 is configured to be supplied to the ridge portion 432 extending in the surface direction of the support plate 21. It spreads on the support plate 21 through the part 432. Therefore, unlike the conventional example, it is not necessary to precisely design the width and depth of the groove, and the chemical solution path can be formed only by arranging the protrusions 432. Can be widely distributed.

By the way, in the said embodiment, flowing water which flowed in in the apparatus collides with an apparatus, and bounces back, and flowing water returns to the exterior of the support plate 21. FIG. In that process, since the running water exposes the chemical solution on the support plate 21, the chemical solution flows out to the toilet and washing is performed. On the other hand, if the apparatus is configured as follows, the flow of running water can be made smooth. Hereinafter, a second embodiment of the present invention relating to this aspect will be described.
(Second Embodiment)
Here, a second embodiment of the present invention will be described with reference to FIGS. 9 and 10. 9 is a cross-sectional view of the apparatus according to the present embodiment, and FIG. 10 is a cross-sectional view taken along the line CC of FIG. This embodiment is different from the first embodiment in that through holes are formed in the support plate, and the other configurations are the same. Is omitted.

  As shown in FIGS. 9 and 10, in the chemical solution supply apparatus according to this embodiment, a circular through hole 215 is formed in the base portion 211 of the support plate 21. The through hole 215 is formed below the outflow hole 428 through which the chemical liquid is discharged. That is, a part of the protruding piece 431 and the protruding portion 432 is disposed above the through hole 215. However, the protrusion 432 is disposed so as to cross the through-hole 215 and to extend outward from the periphery thereof.

  Next, a method of using the chemical solution supply apparatus configured as described above will be described with reference to FIG. FIG. 11 is a side view showing an attached state of the chemical solution supply apparatus. As in the first embodiment, after the chemical solution supply device is installed on the rim of the toilet bowl, when the water is flown, as shown in FIG. 11, the flowed water travels along the toilet wall surface S from the inside of the rim R, Guided to the base 211 side by the movable portion 212 (arrow X). Then, while sweeping the drug solution stored at the boundary portion between the base portion 211 and the movable portion 212, it passes through the through hole 215 formed in the support plate 21 and returns from the bottom surface of the apparatus to the toilet. Some of the running water also flows back to the inner wall surface of the toilet. Thus, the chemical solution is supplied to the toilet inner wall surface S together with running water, and the toilet bowl is cleaned.

  As described above, according to the present embodiment, since the through-hole 215 is formed in the support plate 21, the flowing water that has flowed onto the support plate 21 flows out of the apparatus through the through-hole 215. Therefore, even when the momentum of the flowing water is strong, at least a part of the flowing water flows out to the outside through the through hole 215, so that the momentum of the flowing water on the support plate 21 can be dispersed. As a result, it is possible to prevent the flowing water from entering the chemical liquid container 1 through the outflow hole 428. Moreover, since the chemical solution is not supplied to the outside of the apparatus by utilizing the rebound of the flowing water in the apparatus as in the conventional example, the through-hole 215 is formed on the path of the flowing water that has entered the apparatus, The flow of running water becomes smooth, and the chemical solution can be efficiently supplied to the toilet bowl outside the apparatus.

  Further, even if the chemical solution is supplied onto the support plate 21, the chemical solution may solidify on the support plate 21 if there is no running water for a long time. In this case, as described above, when the through hole 215 is formed on the support plate, it is possible to discharge the chemical solution to the outside through the through hole 215, thereby preventing the liquid from solidifying on the support plate 21. I can do it. In particular, when the support plate 21 is disposed so as to incline downward from the rim side, the chemical liquid does not flow to the rim side. Therefore, if the through hole 215 is formed as described above, the chemical liquid is discharged to the toilet. can do.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to said each embodiment, A various change is possible unless it deviates from the meaning.

  For example, a protrusion part can be made into various aspects. For example, as shown to Fig.12 (a), many protrusions 432 can be provided and a chemical | medical agent can be supplied to a wider range. Moreover, as shown in FIG.12 (b), each protrusion part 432 can also be branched. Furthermore, the protrusion 432 can be not only a straight line but also a curved line such as an arc. The shape of the outflow hole 428 does not have to be an arc shape as described above, and can be a rectangular shape, a circular shape, or the like.

  Moreover, there are various modes for the shapes and positions of the projecting pieces and the through holes. Hereinafter, a description will be given with reference to FIG. FIG. 13A shows an aspect according to this embodiment.
