  More specifically, the chemical solution is discharged from the chemical solution container and supplied into the toilet as follows. In the device of Patent Document 1, a plate with a porous pad or a groove (slot) is disposed as a chemical solution receiving portion below a chemical solution container supported by a housing, and a conduit that extends from the lower end of the chemical solution container and contacts the chemical solution receiving portion is provided. After that, the chemical liquid is supplied to the chemical liquid receiver. The pad or plate of the chemical solution receiving part is disposed horizontally, and when the cleaning water in the toilet flows, the chemical solution collected therein moves into the toilet along with the cleaning water flowing in contact with the chemical solution receiving part.

  In the apparatus of Patent Document 2, the grooved plate constituting the chemical solution receiving portion is arranged so as to descend to 5 to 20 degrees toward the inside of the toilet bowl with the same structure. In this device, the chemical solution supplied from the chemical solution container is easy to move to the groove due to the inclination of the plate, but after the movement, the chemical solution is collected on the plate, and the toilet wash water enters the chemical solution receiving part. By flowing in contact, the drug solution moves into the toilet along with the wash water.

  As described above, in the conventional rim suspension type chemical supply device, the chemical solution is stored in the chemical solution receiving portion, and when the cleaning water flows, it moves into the toilet along with the cleaning water.

  However, since such a rim suspension type chemical supply device is attached by the user in the home or the like, it is not always attached to an appropriate position of the toilet. In order for the chemical solution supply device to function, it is necessary to fix the hook by locking the rim to the rim after the chemical solution receiving portion is in contact with the flushing water of the toilet bowl. However, during installation, the chemical receiving part has not reached the proper position where it comes into contact with the cleaning water, or even if it is in the proper position at the time of installation, it may be out of the proper position during use due to insufficient fixation. There is. In such a case, since the washing water does not reach the chemical solution receiving portion, the chemical solution is left in the chemical solution receiving portion and does not move into the toilet. As a result, there arises a problem that the function of the chemical solution supply apparatus is not exhibited.

  The present invention has been made in order to solve the above-mentioned problem, and can be attached to a toilet rim so that a chemical solution can be mixed into cleaning water in the toilet bowl, and can function even if attached to a position that does not contact cleaning water. It aims at providing the chemical | medical solution supply apparatus which can be exhibited.

(1) The object of the present invention is a chemical solution supply device attached to a toilet rim, the device main body supporting the chemical solution container, and provided in the device main body, connected to the discharge port of the chemical solution container, A chemical solution discharge mechanism that guides and discharges from the discharge port and a hanging member for hanging the apparatus main body on the rim of the toilet bowl. The chemical solution discharge mechanism guides the chemical solution from the communication portion to the discharge port of the chemical solution container. A chemical solution passage extending in the vertical direction so as to be discharged from the lower outflow hole, and a hanging piece extending downward from a position in contact with or close to the opening edge of the outflow hole, the hanging piece having a capillary action To form a lead-out groove for continuously discharging the chemical solution from the outflow hole and discharging it downward from the drooping piece, and the lead-out groove extends downward from the upper end of the drooping piece with a length exceeding 10 mm. chemical supply apparatus characterized by there More is achieved.

  In this chemical solution supply device, the device main body that is hung on the toilet rim by the hanging member includes a chemical solution discharge mechanism that guides and discharges the chemical solution from the discharge port of the chemical solution container, and the chemical solution discharge mechanism is configured to discharge the chemical solution container. Since it has a chemical liquid passage that extends in the vertical direction so that the chemical liquid is guided from the communicating part to the outlet and discharged from the lower outflow hole, the chemical liquid in the chemical container supported by the device body is discharged from the outflow hole through the chemical liquid passage. can do. Further, the apparatus body includes a hanging piece extending downward from a position in contact with or close to the opening edge of the outflow hole, and the dripping piece continuously draws the chemical solution from the outflow hole by capillary action. Since the outlet groove for discharging downward from the hanging piece is formed, the chemical solution is led out from the outflow hole to the leading groove and continues to be discharged downward from the hanging piece. In this way, since the chemical solution is continuously supplied into the toilet bowl, even if the device does not reach the position where it comes into contact with the wash water or may come off from such a position after installation, supply of the chemical solution Is secured and the medicinal effect is sustained.

  (2) In the chemical solution supply apparatus of (1), it is desirable that the lead-out groove extends from the upper end of the drooping piece to a length exceeding 10 mm, and more preferably 12 mm or more. As described in detail below, the lead-out groove has a function of discharging the chemical liquid while guiding it downward by extending downward beyond a predetermined length. Therefore, if the length of the lead-out groove is below the lower limit value, a sufficient discharge amount of the chemical solution cannot be obtained. In addition, if the length of the outlet groove exceeds 20 mm, the device becomes too long downward, making it difficult to install on the toilet, the container becoming too large to be noticeable, or the container becoming dirty with dirt. In some cases, the installation position of the apparatus is likely to change due to the flow of cleaning water. From such a viewpoint, it is preferably 20 mm or less.

  (3) The chemical solution supply apparatus according to (1) or (2) receives the chemical solution discharged from the outlet groove, and causes the chemical solution to flow out together with the cleaning water when it comes into contact with the cleaning water flowing through the toilet. A guide plate can be further provided. Thereby, the chemical | medical solution discharged | emitted from a derivation | leading-out groove | channel is stored to some extent on a guide plate, and if it exceeds storage amount, it will dripped from a guide plate. Therefore, when the wash water of the toilet comes into contact with the guide plate, the stored chemical liquid flows out at a time, and a high medicinal effect can be exhibited immediately after use of the toilet.

  In the case of a chemical supply device attached to the rim of a toilet bowl, the chemical supply device must not interfere with the flow of cleaning water in the toilet bowl, so that the chemical solution supply device has a limited contact area with the cleaning water. Therefore, the chemical solution stored on the guide plate can be discharged by providing the guide plate and guiding the cleaning water onto the guide plate within a range that does not disturb the water flow. Further, by providing the guide plate in this way, it is not necessary to bring the drooping piece into direct contact with the washing water, so that the problem that the washing water flows back through the drooping piece and into the chemical solution container is also avoided. Is done.

  (4) In the chemical solution supply apparatus according to (3), the guide plate may extend from a position below the hanging piece toward the hanging member. By arranging the guide plate in this way, it becomes easier to receive the wash water flowing in the toilet bowl with the guide plate, and the chemical solution on the guide plate can be more reliably discharged together with the wash water.

  (5) In the chemical solution supply apparatus of (3) or (4), the guide plate is inclined so as to descend from the position below the hanging piece toward the hanging member. Can do. Depending on properties such as the viscosity and wettability of the chemical solution, the chemical solution may stay on the guide plate at a position below the drooping piece. By tilting the guide plate in this way, retention is prevented. Can do.

(6) In the chemical liquid supply device according to (3) to (5) , an extension groove that guides the chemical liquid from the hanging piece to the inside by capillary action may be formed on the upper surface of the guide plate. Thereby, the chemical | medical solution transfer from a drooping piece to a guide plate becomes smoother. In addition, more chemical solution can be retained on the guide plate, and more chemical solution can be supplied to the toilet during flushing.

  (7) In the chemical liquid supply device according to (3) to (6), a through hole is formed in the guide plate for allowing the chemical liquid supplied from the hanging piece to drop on the guide plate. Can be. If the liquid medicine can be dripped from the through hole in this way, the mounting state of the liquid medicine supply device on the toilet becomes inadequate, and the flushing water of the toilet does not reach the guide plate or is insufficiently reached. Even if it becomes, a chemical | medical solution can be more reliably supplied in a toilet bowl.

  As described above, according to the present invention, a chemical solution supply apparatus that can be attached to the rim of a toilet bowl and can mix the chemical solution into the wash water in the toilet bowl and that can function even if attached to a position that does not contact the wash water. Can be provided.

  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. The viscosity of the chemical solution stored in the chemical solution container 1 is not particularly limited. For example, the viscosity is 80 to 500 mPa · s at 25 ° C., or 200 to 2000 mPa · s at 5 ° C., preferably 120 to 300 mPa at 25 ° C. · S or 300 to 1200 mPa · s at 5 ° C. The viscosity here is set at a set temperature of 5 ° C. or 25 ° C. in a B-type viscometer (manufactured by Toki Sangyo Co., Ltd .: model number TVB-10 type viscometer). 2. Measured under conditions of stirring conditions of 30 rpm and stirring time of 1 minute.

  As shown in FIGS. 4 and 5, the apparatus main body 2 includes a guide plate 21 that constitutes a bottom surface and a wall body 22 that surrounds the guide plate 21. The guide 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 guide plate 21 has three sides other than the side where the movable portion 212 is provided. The above-described wall body 22 is provided in a U shape in plan view. Therefore, the apparatus main body 2 is formed in a cup shape in which a wall on one side is cut out and is configured such that a part of the base portion 211 and the movable portion 212 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 guide plate 21 will be described in more detail. As shown in FIG. 2, in the guide plate 21 of the present embodiment, the base portion 211 and the movable portion 212 are integrally formed of resin or the like, and the base portion 211 is about 6 degrees toward the movable portion 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 guide 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 guide 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, and thereby the downward inclination is restricted. (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 FIGS. 1 and 2, a substantially rectangular side plate 214 is attached to both side portions of the base portion 211, and an end surface extending vertically toward the movable portion 212 side of the side plate 214 is a movable portion 212. Can be contacted. 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 FIG. 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 guide plate 21, and 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 tube 412 is pierced into the cap 13 of the chemical solution container 1 when the apparatus is used, and serves as a communication portion that breaks the thin film portion 132 and takes out the chemical solution from the discharge port of the chemical solution container. 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 guide plate 21 side. In this way, the communication pipe 412, the fixed pipe 414, the guide groove 426 of the guide pipe 424, and the extension path 427 form a chemical solution passage that extends from the communication portion to the discharge port of the chemical solution container to the outflow hole 428. .

  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 guide plate 21. A space is formed. As will be described later, this space serves as a path for chemicals and running water.

  On the lower surface of the lower member 42, a hanging piece 430 is formed extending downward from a position connecting both ends of the outflow hole 428 described above. The hanging piece 430 has an upper end that abuts against the opening edge of the outflow hole 428, extends across the outflow hole 428 in the diameter direction, and a lower end that is in contact with the upper surface of the guide plate 21. FIG. 8 is an enlarged cross-sectional view centering on the outflow hole 428 and the drooping piece 430, and shows the upper member 41 (a) and the lower member 42 (b) in a separated state. On both the front and back surfaces of the drooping piece 430, lead-out grooves 435 are formed for continuously drawing out the chemical solution from the opening of the outflow hole 428 by capillary action and discharging it downward from the drooping piece. FIG. 9 is an enlarged view showing a transverse section of the hanging piece 430. As illustrated, the lead-out groove 435 is formed to have a triangular cross-sectional shape. The cross-sectional shape of the groove can be various concave shapes such as a square shape and a semi-circular shape, as well as a part of another polygonal shape or an oval shape. Further, the sectional dimension and length of the outlet groove 435 are determined so that the chemical liquid can be led out from the opening of the outflow hole 428 by the capillary action and dropped from the lower end in relation to the viscosity and wettability of the chemical liquid to be used.

  Next, a method of using the chemical solution supply apparatus configured as described above will be described with reference to FIG. FIG. 10 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 it arrange | positions so that the rim | limb R may be pinched | interposed as shown to Fig.10 (a). 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. 10A, 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 gap 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. 10B, 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 solution flows downward through the guide groove 426 and then reaches the lower end openings of the extension path 427 and the outflow hole 428. The reached chemical solution is led out from the outflow hole 428 by the capillary action of the lead-out groove 435 of the hanging piece 430 in contact with the lower end opening edge of the outflow hole 428, and moves downward through the lead-out groove 435. The chemical solution thus moved further moves onto the guide plate 21 at the contact portion between the guide plate 21 and the hanging piece 430 and drops from the guide plate when the amount stored in the guide plate 21 is exceeded. In this embodiment, as shown in FIG. 1, a through hole 250 that penetrates the guide plate in the vertical direction is formed at a position near the movable portion 212 in the base portion 211 of the guide plate 21. Therefore, the through hole 250 has an effect of allowing the chemical solution supplied from the hanging piece 430 to the guide plate 21 to pass therethrough and discharging it downward. If the liquid medicine can be dropped from the through-hole 250 in this way, the state in which the liquid medicine supply device is attached to the toilet becomes inadequate, and the flushing water of the toilet does not reach the guide plate or is insufficiently reached. Even if it becomes, a chemical | medical solution can be more reliably supplied in a toilet bowl.

  Further, an extended groove 216 (indicated by a one-dot chain line in FIG. 1) for guiding the chemical solution into the groove by capillary action can be formed on the upper surface of the guide plate 21. By doing so, the transfer of the chemical solution from the hanging piece 430 to the guide plate 21 becomes smoother. In addition, more chemical liquid can be retained on the guide plate 21, and more chemical liquid can be supplied to the toilet at the time of flushing.

  In this embodiment, since the lower end of the drooping piece 430 is in contact with the upper surface of the guide plate 21, the chemical moves from the outlet groove 435 to the guide plate 21 through the contact portion, and the discharge from the outlet groove is smooth. To be done. However, depending on properties such as the viscosity and wettability of the chemical solution, the chemical solution may stay at the contact portion between the hanging piece and the guide plate, thereby preventing discharge from the outlet groove. In such a case, the guide plate is tilted so as to descend from the contact point with the hanging piece toward the hanging member 3 (toilet rim side), or a chemical solution is applied to the upper surface of the guide plate by capillary action. It is desirable to prevent the stagnation by forming an extended groove that guides the liquid into the groove or by using both. On the other hand, the hanging piece may have a lower end that extends to a position apart from the upper surface of the guide plate. In this case, the chemical solution is dropped from the drooping piece onto the guide plate, or when the gap between the two is small, the chemical solution is transferred to fill the gap. Thereby, the residence in the contact location of a drooping piece and a guide plate is prevented. Also in this case, one or both of the inclination and the expansion groove can be employed for the guide plate.

  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 flush water is poured into the toilet bowl, the flushed water travels along the toilet bowl inner wall surface S from the inside of the rim R as shown in FIG. Guided to the base 211 side (arrow X). Then, while the chemical solution on the guide plate 21 is exposed, it flows out from the water flow hole 25 and the through-hole 250 or bounces off against the wall body 22 in the apparatus and flows out from the open part 23 to the outside of the apparatus. Thus, the chemical solution is supplied to the toilet inner wall surface S together with running water, and the toilet bowl is cleaned.

  The washing water flowing onto the guide plate 21 may flow backward through the chemical solution discharge mechanism 4 and enter the chemical solution container 1, but this is dealt with as follows. That is, in the apparatus according to the present embodiment, the chemical solution is discharged onto the guide plate 21 through the guide groove 426, the extension path 427, and the outflow hole 428, through the outlet groove 435 of the drooping piece 430. Accordingly, the cleaning water from the guide plate toward the chemical solution container must move with the drooping piece 430 upward. In this case, the drooping piece and the lead-out groove are elongated downward so that the lead-out groove 435 easily guides the chemical solution from the lower end opening of the outflow hole 428, so that the washing water rises and reaches the outflow hole 428. Make it more difficult. Further, since the extension path 427 extends horizontally, the water that has flowed upward through the lead-out groove 435 of the hanging piece 430 passes through the extension path 427 that extends once horizontally, and then passes through the guide groove 426 that extends further vertically. If it does not pass, the chemical solution container 1 is not reached. Thus, in this apparatus, since the vertical path | route from the guide plate 21 to the chemical | medical solution container 1 is formed, the penetration | invasion of water is prevented and the path | route extended horizontally is arrange | positioned in the middle of the vertical path | route further. Therefore, it is possible to prevent water from entering more reliably.

  As described above, according to the present embodiment, the chemical solution in the chemical solution container reaches the outflow hole 428 through the above-described chemical solution passage, is led out to the lead-out groove 435 of the hanging piece 430, and is spread and stored on the guide plate 21. On the other hand, when the amount of storage is exceeded, it drops from the guide plate 21 into the toilet bowl. In this way, since the chemical solution is continuously supplied into the toilet bowl, even if the device does not reach the position where it comes into contact with the wash water or may come off from such a position after installation, supply of the chemical solution Is secured and the medicinal effect is sustained.

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.
[Experimental example]
In order to verify the performance of the chemical solution supply apparatus according to the present invention, the following experiment was performed.
(1) Chemical Solution Supply Device The chemical solution supply device according to the embodiment is basically used, and the hanging piece has the specifications described below. When the lead-out groove is provided, it is formed so as to extend over the entire length in the vertical direction of the drooping piece, so that the drooping piece and the lead-out groove have the same length.
(2) Chemical solution The fragrance cleaning agent for flush toilets composed of surfactant, fragrance, and water was used as the basic chemical solution, and the changes described below were made when necessary. This chemical solution had a viscosity of 240 mPa · s at 25 ° C. and 690 mPa · s at 5 ° C. In addition, the viscosity is set to 25 ° C. or 5 ° C. in the B type viscometer (manufactured by Toki Sangyo Co., Ltd .: model number TVB-10 type viscometer). 2. Measurement was performed under the conditions of stirring at 30 rpm and stirring time of 1 minute.

(3) Experimental method
(A) Measurement of weight loss under standing A chemical container filled with 36 g of chemical solution was attached to the chemical solution supply device, and this was left in the room to examine the decrease of the chemical solution. The measurement was performed every 24 to 72 hours, and the weight (g) of the chemical solution remaining in the chemical solution container was measured.
(B) Measurement of weight loss under usage conditions A chemical container filled with 36 g of chemical solution is attached to the chemical solution supply device, and this is locked to the rim of a flush toilet C780B type manufactured by TOTO Corporation. It was installed to do. When flushing flush water in the toilet, the water tank is operated every 60 minutes to flush the water in the tank (it will be flushed 24 times a day), and flushing is performed a predetermined number of times (24 to 72). Each time, the remaining amount (weight) of the chemical solution in the chemical solution container was measured.

The number of samples with the same specifications for each experiment is three. The average value was represented on the graph.
(4) Experiment contents and results
(A) Measurement of weight loss when left unattended
(a) Performance of the device of the present invention A chemical supply device (Examples 1 and 2) provided with a hanging piece with a lead-out groove having the following length
Using the chemical solution supply apparatus provided with the hanging piece with the lead-out groove shown in the first embodiment, the length L of the hanging piece (see FIG. 8B) is set to the following dimensions, and the weight is reduced when left standing. Measurements were made. The length L is the length from the lower edge of the outflow hole 428 to the lower end of the hanging piece 430.
Example 1: L = 12 mm
Example 2: L = 17 mm
The results are shown in graph 1. Graph 1 shows the results of Examples 1 and 2 as curves (i) and (ii), respectively.

As can be seen from the graph, the amount of medicinal solution is steadily decreasing with time, and the longer the drooping piece, the faster the medicinal solution decrease rate. ing.
(b) Performance of Comparative Example (Comparative Examples 1, 2, 3)
As a comparative example, a chemical solution supply device (Comparative Example 1) having a hanging piece (no lead-out groove) having the same shape and size as in Example 1 and a flat surface, and the hanging piece having the shape shown in the embodiment in the vertical direction The weight loss measurement was performed using a chemical supply apparatus having a length of 3 mm (Comparative Example 2) and a length of 10 mm (Comparative Example 3). The shape and number of lead-out grooves are the same as in the embodiment.

  The result of the experiment is shown in graph 2. Graph 2 shows the results of Comparative Examples 1, 2, and 3 as curves (iii), (iv), and (v), respectively, and shows the results of Example 1 (curve (i)) side by side for reference.

As seen in the graph, in Comparative Examples 1 and 2, only a small amount of chemical solution is discharged from the chemical solution supply device, and in Comparative Example 3, a certain amount is discharged, but this is not sufficient to obtain the necessary effect of the chemical solution. It is enough. Even if the hanging piece has a flat surface, the chemical solution is slightly decreased because the buffering function against the change in the room temperature functions by the buffer chamber, etc., and a small amount flows out with the flow of the chemical solution at that time Although it is considered to be a small amount, it is thought that weight loss due to drying of the chemical liquid flowing out to the chemical liquid holder, volatilization of the fragrance, impact during weight measurement, etc. is also affected.
(c) Relationship with chemical viscosity (Examples 3 and 4)
In order to investigate how the viscosity of the chemical solution is related to the appropriate value of the derived groove length, use a chemical solution with a different viscosity, and use a rectangular plate with the following dimensions as a hanging piece to measure the weight loss. Was done. This chemical solution had a viscosity of 80 mPa · s at 25 ° C. and 305 mPa · s at 5 ° C. The chemical formulation and the viscosity measurement method are the same as described above.
-Example 3: L = 12mm
Example 4: L = 17 mm
Graph 3 shows the results of Examples 3 and 4 as curves (vi) and (vii), respectively. As shown in the graph 3 and the results of Examples 1 and 2 in the previous graph 1 (lengths of drooping pieces 12 mm and 17 mm; curves (i) and (ii)), it is maintained even when the viscosity of the chemical changes. There has been no significant change in performance.

Therefore, it is clear that the continuous outflow of the chemical liquid is ensured regardless of the viscosity of the chemical liquid when the length of the outlet groove exceeds 10 mm.
(B) Weight loss measurement under usage conditions Using the chemical solution supply apparatuses of Examples 1 and 2 and Comparative Example 1, weight loss measurement was performed under usage conditions. The results are shown in graph 4. Graph 4 shows the curves (viii) and (ix) using the devices of Examples 1 and 2, respectively, and the curves (x) and (xi) using the devices of Comparative Examples 1 and 2, respectively. Yes. In this graph, the horizontal axis represents the number of flashes. As can be seen from the graph, in the examples, there is no significant difference between them, and the weight loss is almost constant and smooth, whereas in Comparative Examples 1 and 2, the weight loss is not much as in the case of the test result in (A). I can't. This is because in Comparative Example 1, the hanging piece has no outlet groove, and in Comparative Example 2, the hanging piece and the outlet groove are short. As a result, the chemical solution reaching the lower end opening of the outlet is not led out to the surface of the hanging piece. Yes. In particular, since this chemical supply device is a type that is attached to the rim of a toilet bowl, a guide plate is provided so that the cleaning water is guided onto the guide plate as long as the cleaning water flow is not hindered. The hanging piece itself has a structure that makes it difficult to directly contact the washing water. Therefore, as in these comparative examples, when the drug solution does not transfer from the drooping piece to the guide plate, the flushing is not promoted and the function does not function in use. On the other hand, it is shown that the container of the example is a container suitable for use because the chemical liquid is steadily reduced even when left as described above and the liquid is steadily reduced even when flushed.
(5) Summary From the above experiments, it is clear that the example of the present invention has an effect that cannot be obtained from the comparative example, that is, the continuous supply of the chemical solution is ensured even when left unattended. Therefore, the chemical solution supply apparatus of the embodiment can mix the chemical solution with the wash water in the toilet bowl and can perform the function even when attached to a position not in contact with the wash water.
