Description

  The present invention is attached to a rim of a toilet bowl and supplies a chemical solution for washing the toilet bowl, or is disposed in a hand washing part at the upper part of a water storage tank in a flush toilet, and the chemical liquid is stored in the water storage tank together with water supplied to the hand washing part. The present invention relates to a chemical solution supply apparatus for supplying a liquid.

  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 apparatus described in Patent Document 1 is provided with a chemical solution container so as to be hung on a toilet rim, and a plate for receiving the chemical solution is attached below the chemical solution container. 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 via a discharge hole from a chemical | medical solution container by flowing water. As a result, the toilet bowl is washed, and the fragrance effect can be obtained by the fragrance contained in the chemical solution.
Special table 2003-517124 gazette

  By the way, the said chemical | medical solution supply apparatus is comprised so that the chemical | medical solution discharged | emitted from the chemical | medical solution container may flow directly on a plate through a discharge hole. For this reason, when the momentum of the flowing water flowing onto the plate is strong, the chemical solution on the plate may not only be exposed, but may flow into the discharge hole. Thus, the flowing water that has flowed into the discharge hole may flow into the chemical solution container, which causes a problem that the chemical solution in the container is diluted. As a result, the effect of the chemical solution as a cleaning agent or fragrance may be reduced.

  Such a problem is a problem that may occur not only in the type attached to the rim of the toilet bowl, but also in the chemical solution supply apparatus of the type that is disposed in the hand-washing section above the water storage tank. That is, in this type of apparatus, the water supplied to the hand-washing section flows into the apparatus, and this flowing water flows out of the chemical solution in the apparatus and flows out to the outside, and then is supplied into the water storage tank. Therefore, since the flowing water entering the apparatus may flow into the chemical container, the above-described problem may occur.

  The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a chemical solution supply apparatus that can prevent flowing water from flowing into a chemical solution container.

1st this invention is a chemical | medical solution supply apparatus attached to the rim of the toilet bowl in a flush toilet, Comprising: It was made | formed in order to solve the said problem, The chemical | medical solution container which accommodates a chemical | medical solution and has the discharge port of the said chemical | medical solution And a chemical solution discharging mechanism connected to the discharge port for guiding the chemical solution in the chemical solution container to the outside, and a support member for supporting the chemical solution discharged from the chemical solution discharge mechanism in contact with running water flowing in the toilet. A chemical liquid container, the chemical liquid discharge mechanism, and a hanging member for suspending the support member on a rim of a toilet bowl, wherein the chemical liquid discharge mechanism is disposed between the chemical liquid container and the support member. The chemical solution discharge mechanism includes: a guide path that guides the chemical solution downward from the chemical solution container; at least one extension path that communicates with the guide path and extends substantially horizontally from the guide path; and the extension path Communicate with And an outflow hole for discharging the chemical solution that has passed through the extension path to the support member side.

A second aspect of the present invention is a chemical supply device that is disposed in a hand wash section at the upper part of a water storage tank in a flush toilet and supplies a chemical liquid into the water storage tank together with water supplied to the hand wash section, which solves the above problem It is made for this purpose, contains a chemical solution, has a discharge port for the chemical solution, supports the chemical solution container, is disposed on the hand-washing portion, is disposed in the support body , a drug solution discharge mechanism wherein connected to the outlet leading to outside the chemical in the chemical container, provided on the lower surface of said support, for guiding the liquid medicine discharged from the drug solution discharge mechanism downwardly of the support And a guide member for guiding the chemical solution downward from the chemical solution container side, and at least one extension passage communicating with the guide passage and extending in a substantially horizontal direction from the guide passage. The above Long path and communicating, and a, and an outflow hole for discharging the liquid chemical which passes through the extension path to the guide member.

The third aspect of the present invention is a chemical supply apparatus that is disposed in a hand wash section above a water storage tank in a flush toilet and supplies the chemical liquid into the water storage tank together with water supplied to the hand wash section. A chemical solution supply device that is arranged in a hand washing section at the upper part of a water storage tank in a flush toilet and supplies the chemical liquid into the water storage tank together with water supplied to the hand washing section. A chemical solution container that contains the chemical solution outlet, a chemical solution discharge mechanism that is connected to the discharge port and guides the chemical solution in the chemical solution container to the outside, and is provided below the chemical solution discharge mechanism; A guide member for guiding the chemical liquid discharged from the discharge mechanism, and the chemical liquid discharge mechanism communicates with the guide path for guiding the chemical liquid downward from the chemical liquid container side and the guide path. Comprises at least one extension path extends in a substantially horizontal direction, the threading extending passage and communicates, and an outflow hole for discharging the liquid chemical which passes through the extension passage on the guide member, from.

  According to the first to third aspects of the present invention, the guide path extending downward and the extension path extending substantially horizontally are provided in the path of the chemical solution from the chemical solution container to the outflow hole. Therefore, at the time of flushing, the flowing water that has entered the chemical solution supply apparatus and has flowed into the outflow hole does not reach the chemical solution container unless it passes through a horizontally extending extension path and further passes through a guide path extending upward. Therefore, since the horizontally extending path is arranged in the upward path leading to the chemical container in the flowing water that has entered the apparatus, it becomes difficult for water to enter, and as a result, the flowing water enters the chemical container. It can be surely prevented.

  The extension path described above can have various configurations. For example, it may be configured by one extension path, or two or more extension paths may be provided and merged at the outflow hole. When two or more extension paths are provided, for example, they can be configured to extend in a circular arc shape on both sides of the guide path so that each central angle is 60 degrees or more, and more preferably 90 degrees or more. By doing so, the path from the guide path to the outflow hole can be made long and complicated, and water can be more reliably prevented. Moreover, although the guide path is configured to extend downward, it does not necessarily extend in the vertical direction, and may extend downward in an oblique direction. Further, the extension path does not necessarily have to extend in the correct horizontal direction, and may be slightly deviated from the horizontal direction as long as it can serve to prevent water from entering the guide path.

  By the way, it is preferable to consider the following points regarding the extension road. For example, assuming that the cross-sectional area of the extension path is constant, if the volume is too small, there is a possibility that intrusion of running water that flows backward through the extension path cannot be prevented. On the other hand, if the volume is too large, in the chemical solution discharge mechanism of the present invention, the chemical solution that passes through the guide path flows downward, so that the chemical solution flows through the extension path by the action of its own weight, but for example, the viscosity of the chemical solution is extremely large In some cases, there is a possibility that the chemical solution passes through the extension path and flows too slowly or stops flowing to the outflow hole.

  In addition, for example, assuming that the volume of the extension path is constant, if the cross-sectional area is too large, there is a possibility that intrusion of running water that flows backward through the extension path cannot be prevented. On the other hand, if the cross-sectional area is too small, in this mechanism, the chemical solution that passes through the guide path flows downward, so that the chemical solution flows through the extension path due to its own weight, but for example, when the viscosity of the chemical solution is extremely large There is a possibility that the chemical solution passes through the extension path and flows too slowly or stops flowing to the outflow hole.

In view of the above, the volume of each extension line is preferably 0.05 to 0.3 mm ^3, and more preferably a 0.07~0.15mm ^3. Moreover, it is preferable that the cross-sectional area of each extension path is 0.02-0.1 mm < ² >, and it is further more preferable that it is 0.03-0.05 mm < ² >. And it is especially preferable that both the volume and the cross-sectional area of the extension path are within the above range.

  Moreover, in the said 1st to 3rd invention, the wall member surrounding the circumference | surroundings of an outflow hole can be provided. When such a wall member is provided, an air wall can be formed in a region surrounded by the wall member, thereby preventing flowing water from flowing into the outflow hole. For example, such a wall member can be configured to extend downward or obliquely downward from the periphery of the outflow hole. Further, a wall member may be formed upward from a member below the outflow hole, for example, a support member that receives the liquid, thereby surrounding the outflow hole. Or the circumference | surroundings of an outflow hole can also be enclosed by connecting the wall member extended below from the circumference | surroundings of the outflow hole, and the wall member extended upwards from the downward direction.

  In particular, in the first aspect of the invention, the chemical solution discharge mechanism can be provided with a wall member that surrounds the periphery of the outflow hole and protrudes toward the support member.

  In the third aspect, the guide member can have various configurations. For example, the guide member can be protruded downward from the chemical solution discharge mechanism and inserted into the discharge port of the hand-washing portion, or can be extended laterally or obliquely downward. By carrying out like this, the chemical | medical solution discharged | emitted from the chemical | medical solution discharge | emission mechanism can be spread over a wide range, and it can make it easy to make it contact with flowing water at the time of a flush. Thus, it is preferable to extend the guide member to a position where it is easy to contact running water.

  According to the chemical solution supply apparatus of the present invention, it is possible to prevent flowing water from flowing into the chemical solution container.

(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. Further, a space through which the chemical solution passes, that is, an extension path 427 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, on 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, about half of 180 degrees. 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. Incidentally, the volume of each extension passage 427 is preferably 0.05 to 0.3 mm ^3, and more preferably a 0.07~0.15mm ^3. Further, the cross-sectional area of the extension passage 427 is preferably 0.02 to 0.1 mm ^2, further preferably 0.03~0.05mm ^2.

  As shown in FIG. 6, a pair of leg portions 429 are attached to both ends of the lower end 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. Since the base portion 211 of the support plate 21 is slightly inclined downward, the chemical solution flows downward and is accumulated at the boundary portion with the movable portion 212. At this time, the fragrance | flavor contained in a chemical | medical solution volatilizes and the aroma effect is acquired.

  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.

  As described above, according to the present embodiment, the flowing water flowing into the apparatus is prevented from flowing into the chemical solution container 1 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. Therefore, in this apparatus, since the path | route extended horizontally is arrange | positioned in the path | route of the perpendicular direction from the support plate 21 to the chemical | medical solution container 1, the approach of water can be prevented.

  The wall member 423 extending below the lower member 42 forms a space that surrounds the periphery of the outflow hole 428, and an air wall that covers the outflow hole 428 is formed by this space. Therefore, the flowing water can be prevented from entering the outflow hole 428 also by this space.

The upper wall 340 of the cylindrical portion 310 is located at a position higher than the lower step wall 3410 on the outside of the pair of cylindrical portions 310 and surrounds the periphery of the supply unit 400, and has an upper step wall 3420 having a crescent shape in plan view. It consists of and. The upper stage wall 3420 is provided with a plurality of air circulation holes 3430 (four in this example) communicating with the inside of the cover member 300. The cover member 300 is combined with a lower member 2000 of the apparatus main body 200, which will be described later, so that a buffer space 600 for holding a chemical solution is formed between them.

  FIG. 13 is a plan view (a) and a front sectional view (b) of the apparatus main body, and FIG. 14 is a perspective view (a) showing the apparatus main body and the cover member in an exploded state, and a state in which these are combined. FIG. 15 is a partial perspective view (a) of the chemical solution discharge mechanism and a cross-sectional view taken along the line BB of FIG. 15 (b).

  As shown in FIG. 13, the apparatus main body 200 includes a plate-like base portion 210 and a wall body 220 formed so as to surround the periphery thereof. A lower member 2000 connected to the cover member 300 is provided on the base 210. The lower member 2000 includes a bowl-shaped outer wall 230 that fits on the outer surface of the inner wall 330 of the cover member 300. And the buffer space 600 mentioned above is formed between a pair of cylindrical parts 310 and the base 210 by fitting the cover member 300 in the outer side wall 230 (refer FIG.14 (b)). The lower member 2000 may be provided integrally with the apparatus main body 200 as described above, or may be separately formed and connected to the apparatus main body 200 by bonding, screwing, or the like. The wall body 220 is formed with a plurality of water flow holes 240 for discharging water that has flowed into the apparatus to the outside.

  The lower member 2000 will be described in more detail. As shown in FIG. 13, a cylindrical guide column 420 that fits in the fixed tube 4120 of the cover member 300 and a periphery of the cylindrical guide column 420 are disposed inside the outer wall 230. The provided circular fixed wall 430 is provided at two locations. A guide groove 4210 extending in the vertical direction is formed on the outer peripheral surface of the guide post 420. Here, as shown in FIG. 15, since the guide column 420 is fitted inside the fixed pipe 4120, a chemical liquid passage (guide path) is formed by the inner wall surface of the fixed pipe 4120 and the guide groove 4210. A space through which the chemical solution passes, that is, an extension path 4270 is also formed between the bottom surface of the gap between the guide column 420 and the fixed wall 430 and the lower end portion of the fixed tube 4120. More specifically, at the bottom surface of the gap, about 90 degrees on each side of the guide groove 4210 constitutes an extension path 4270 for the chemical solution, and on the opposite side to the guide groove 4210, about half of 180 degrees. A circular outflow hole 4280 is formed. And the chemical | medical solution which passed the extension path 4270 flows out from the outflow hole 4280 to the guide member 500 side mentioned later.

  The guide member 500 is formed in a plate shape having a width straddling the pair of outflow holes 4280, and the upper end portion is in contact with the opening edge of the lower end of each outflow hole 4280 and extends downward. A large number of narrow grooves 510 extending in the vertical direction are formed in the planar portions of the front and back surfaces of the guide member 500 in order to spread the chemical solution led out from the outflow hole 4280 (see FIG. 9A).

  Also, on the bottom surface of the apparatus main body 200, two long legs 250 that are spaced from the front and back surfaces of the guide member 500, and four short legs 260 disposed around the long legs 250, are directed downward. It is provided to extend. Of these legs 250, 260, the long legs 250 can be inserted into the drainage port H of the hand-washing section as described above, and each short leg 260 is in a state where the long legs 250 are inserted into the drainage port H. The apparatus main body 200 is supported substantially horizontally on the hand-washing portion Z. Further, a shielding member 270 extends downward from the bottom surface of the apparatus main body 200 between the guide member 500 and the long legs 250. The guide member 500 and the shielding member 270 are shorter in length in this order than the long leg 250, the long leg 250 positions the apparatus main body 200 at the drain outlet, and the guide member 500 is water that flows down to the drain outlet H. The length of each of the shielding members 270 is determined so that the flowing water does not reach the outflow holes 4280.

  The chemical solution supply apparatus configured as described above is used as follows. First, after the outer wall 230 of the apparatus main body 200 is fitted to the outer side of the inner wall 330 of the cover member 300 to form the buffer space 600, the chemical container 100 is discharged to the communication pipe 410 extending upward from the cover member 300. It is assembled by inserting the outlet 120.

  Subsequently, the flow of the chemical solution will be described. A part of the chemical liquid flowing out from the chemical liquid container 100 to the chemical liquid discharging mechanism flows into the buffer space 600 through the communication pipe 410 and the chemical liquid communication hole 4140. On the other hand, as shown in FIG. 15, the remaining chemical solution passes through the guide groove 4210 and flows downward, then flows out to the guide member 500 through the extension path 4270 and the outflow hole 4280, and is held there. And the chemical | medical solution on the guide member 500 is washed away by the flowing water supplied at the time of flushing, and flows into a water storage tank. Note that the role of the buffer space 600 is the same as that of the first embodiment, and a description thereof will be omitted.

  As described above, according to this embodiment, the same effect as that of the first embodiment can be obtained. That is, since the chemical liquid flows out onto the guide member 500 through the guide groove 4210 and the extension path 4270, the flowing water must pass through the extension path 4270 extending horizontally and then pass through the guide groove 4210 extending further vertically. The chemical solution container 100 is not reached. Therefore, it is possible to prevent water from entering the chemical container.

Further, since the lower end portion of the guide member 500 is inserted into the drainage port H of the hand washing unit, the discharged chemical solution is guided into the drainage port H along the guide member 500. Regardless of the shape of the handwashing section, the running water from the water discharge tap flows into the drainage port H of the handwashing section, so that the chemical solution on the guide member 500 is reliably washed away by the running water. Therefore, the chemical solution supply apparatus according to the present embodiment can be used in various toilets without depending on, for example, the position of the water discharge tap and the form of the hand-washing portion. Further, since the chemical solution on the guide member 500 flows directly into the drainage port H by being washed away with running water, even if the chemical solution contains a component such as a pigment, the hand-washing portion is caused by this pigment. It can be prevented from being soiled.
(Third embodiment)
In the said 2nd Embodiment, although the guide member protrudes below the support body and is directly guided to the inside of a drainage structure, it can also be comprised so that it may flow out on a hand-washing part. Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. FIG. 16 is a front view (a) and a side view (b) of the chemical liquid supply apparatus according to the third embodiment, FIG. 17 is an exploded view of FIG. 16, and FIG. 18 is a plan view (a) and a front view (b) of the guide member. ).

  As shown in FIG. 16, the chemical solution supply apparatus includes a chemical solution container 700 that stores a chemical solution such as an aromatic cleaning agent, and a support 701 that supports the chemical solution container 700 and is disposed on the hand-washing portion Z. Yes. The support is formed in a cup shape, and a chemical solution discharge mechanism 702 that discharges the chemical solution discharged from the chemical solution container 700 and a plate shape that guides the chemical solution that has passed through the chemical solution discharge mechanism 702 to the outside of the support body 701 are formed therein. The guide member 703 is arranged. A plurality of legs 720 are provided on the lower surface of the support body 701 so as to protrude downward and to be inserted into the drain outlet H of the hand-washing portion Z. Further, as will be described later, in addition to an opening 704 from which the guide member 703 protrudes, a plurality of openings 705 for allowing water to flow in are formed on the side surface of the support body 701.

  As shown in FIG. 17, the chemical solution container 700 is formed in a dome shape, and a discharge port 706 for discharging the chemical solution is formed at the lower end. The chemical solution discharging mechanism 702 includes a main body 707 formed in a U-shaped box shape when viewed from the front, and a communication pipe 708 disposed on the upper portion. The communication pipe 708 has a tip cut obliquely and is inserted into the discharge port 706 of the chemical solution container. Then, the chemical solution in the chemical solution container 700 flows into the main body 707 through the communication pipe 708. A discharge structure equivalent to that shown in FIG. 15 is arranged inside the main body 707, and the chemical solution that has passed through the discharge structure is discharged to a plate-shaped guide member 703 provided on the lower surface of the main body 707. The discharge structure will be described with reference to FIG. Further, the main body 707 is provided with a buffer space 600 similar to that shown in FIG. 14 and plays the same role as in the first embodiment.

  As shown in FIG. 18, the guide member 703 includes a rectangular base portion 709 and a pair of guide plates 710 inclined downward from both side edges (upper and lower sides in the figure) of the base portion 709. The base 709 is disposed at a position close to the outflow hole 4280 of the discharge structure, and receives the chemical liquid flowing out from the outflow hole 4280. A plurality of grooves 711 through which the chemical solution can flow are formed in the vicinity of the outflow hole 4280 in the base 709 and in the vicinity thereof in the width direction (the left-right direction in the figure). The guide groove 712 constitutes the one arranged in the above. The guide groove 712 extends across the base portion 709 to the end portions of both guide plates 710, and guides the chemical solution from the base portion 709 to the guide plate 710 side. Further, as shown in FIG. 16B, the end portion of each guide plate 710 protrudes from an opening 704 formed from the bottom surface to the side surface of the support body 701.

  The chemical solution supply apparatus configured as described above operates as follows. First, the chemical solution flows out from the chemical solution container 700 and flows out onto the guide member 703 via the chemical solution supply mechanism. On the guide member 703, a part is held on the base 709 and flows out on the guide plate 710 along the guide groove 712 and is held on this. When water is supplied at the time of flushing, the water comes into contact with the chemical solution on the guide plate 710 protruding from the opening 704 of the support 701 and is washed away. Further, part of the flowing water flows into the inside from the opening 705 of the support body 701, and the chemical solution on the base 709 of the guide member 703 is also washed away. Thus, the chemical liquid flows out onto the hand-washing section Z together with running water and flows into the water storage tank from the drainage port H.

  As described above, according to this embodiment, the same effects as those of the first and second embodiments can be obtained. That is, since the chemical solution flows out onto the guide member 703 via the guide groove 4210 and the extension path 4270 shown in FIG. 15, the flowing water once passes through the extension path 4270 extending horizontally and then passes through the guide groove 4210 extending further vertically. If it does not pass, the chemical solution container 700 is not reached. Therefore, it is possible to prevent water from entering the chemical liquid container 700.

  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, the positions of the guide grooves 426 and 4210 are not particularly limited, and may be formed at any position on the outer peripheral surface of the communication pipe 424 and the guide column 420. In addition, the extension paths 427 and 4270 are formed so as to draw an arc as in the above embodiment, but the shape and the shape of the extension paths 427 and 4270 are particularly limited as long as they extend from the guide grooves 426 and 4210 directed downward. It may not be linear. Moreover, the number can also be provided 1 or 3 or more. Furthermore, in the above-described embodiment, the two extension paths 427 and 4270 are formed so as to merge at one outflow hole 428 and 4280, but a plurality of outflow holes may be provided. Also, a plurality of guide grooves 426 and 4210 can be provided. In each of the above embodiments, the guide path is formed using the groove, but a pipe member may be used.

  In the second embodiment, two supply units 400 are formed so that a pair of guide grooves 4210 are formed, but only one supply unit 400 may be provided. In addition, the shape is not limited to the shape of the guide member 500, and the shape may be other than a flat plate shape as long as the chemical solution can be held, and the guide member 500 is not vertical but at a horizontal or other angle. It can also be arranged.

  Moreover, as shown in 3rd Embodiment, the structure of the guide member 703 is not specifically limited, In addition to diagonally downward, it can also be extended to the side. Further, the guide member 703 is not particularly limited as long as it has a shape that can receive a chemical solution as well as a plate shape, and can have various shapes such as a rod shape and a block shape. Further, the support body 701 is not necessarily required, and the shape is not particularly limited as long as the chemical liquid container 700, the chemical liquid discharge mechanism 702, and the guide member 703 can be supported by any configuration. This also applies to the first and second embodiments.
