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 adapted to expose the chemical solution supplied on the plate by running water, but if the device is attached with the end opposite to the rim side inclined downward, the chemical solution is There is a risk of flowing on the opposite side of the rim on the plate. In this state, since the chemical solution accumulates at a position away from the rim on the plate, it becomes difficult to wipe it with running water, and the desired aroma and cleaning effect may not be obtained.

  The present invention has been made to solve the above-described problems, and provides a chemical solution supply device capable of obtaining a fragrance and a cleaning effect even when the device is mounted to be inclined with respect to the rim. With the goal.

  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 hanging member for hanging, and the chemical solution discharge mechanism has an outflow hole that opens toward the support member and discharges the chemical solution, and the support member is displaced from immediately below the outflow hole. At least one through hole facing the outside is formed in the vicinity of the position or on the opposite side of the rim from the position.

  According to this configuration, in the support member, the through hole is formed in the vicinity of the position shifted from directly below the outflow hole or on the side opposite to the rim from the position. Therefore, when the apparatus is attached to be inclined with respect to the rim, for example, even if the chemical liquid flows on the support member on the side opposite to the rim, it flows out of the apparatus from the through hole. That is, since a chemical | medical solution flows into a toilet bowl, it can be made to contact running water. Therefore, even when the apparatus is not attached to the rim at a desired angle, the chemical solution can be brought into contact with running water, and a desired aroma and cleaning effect can be obtained.

  In the said apparatus, a shielding wall can be formed in a support member between the direct underflow hole and a through-hole. If not provided such a shroud, the device is tilted, the drug solution, there is a possibility that flows endlessly from the through hole. As a result, there is a possibility that the planned operation that the running water exposes the chemical solution on the support member may not be performed. In order to prevent this, when the shielding wall as described above is provided, only the chemical solution that has passed through the shielding wall flows out from the through hole, so that a certain amount of the chemical solution remains on the support member. Therefore, the chemical solution on the support member is exposed by the flowing water.

  Moreover, in the said apparatus, the chemical | medical solution discharged | emitted from the outflow hole is supplied, and while being protruded to the support member side, at least 1 protrusion part extended in the surface direction of a support member can be provided.

  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, the chemical solution can be reliably spread over a wide range with a simple structure. In addition, it is preferable to provide the support member with an appropriate inclination for flowing the chemical solution. To provide such an inclination, it is necessary to consider the design of the entire apparatus. If the chemical solution is allowed to flow through the strip portion, for example, an inclination can be provided only in the protruding portion, and by doing so, the flow of the chemical solution can be easily formed. As a result, the design is simplified.

  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 the support member, a restriction wall that restricts the flow of the chemical liquid can be provided in a part of the flow path of the chemical liquid toward the rim. Thereby, since the flow path of the chemical liquid toward the rim side is restricted, it is possible to prevent the chemical liquid from flowing out excessively. As a result, the chemical solution can be prevented from being used up early.

  According to the chemical solution supply apparatus according to the present invention, it is possible to obtain a fragrance and a cleaning effect even when the apparatus is attached to be inclined with respect to the rim.

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

  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. As shown in FIGS. 3 and 4, two triangular through holes 2111 are formed in the base portion 211. Each through-hole 2111 is arranged on both sides immediately below a chemical solution outflow hole 428 in a chemical solution discharge mechanism 4 described later. In addition, a pair of shielding walls 2112 that are inclined and extend toward the movable portion 212 are formed on the base portion 211 so as to pass through one side of each through-hole 2111. Both the shielding walls 2112 extend so as to extend toward the bottom so as to be separated from each other toward the movable portion 212 side. In addition, ends of the both shielding walls 2112 opposite to the rim are also connected by the shielding walls 2112. That is, the three shielding walls 2112 are arranged so as to partition the through hole 2111 and the position immediately below the outflow hole 428.

  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 outflow 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 outflow 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, 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 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 first peripheral wall 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 first peripheral wall 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. The protrusion 432 is formed with a plurality of grooves extending downward, as shown in FIG. An arc-shaped second peripheral wall 435 is provided on the opposite side of the first peripheral wall 431 with the outflow hole 428 interposed therebetween. As shown in FIG. 2, the inner wall surfaces of the first peripheral wall 431 and the second peripheral wall 435 sandwiching the front and rear of the outflow hole 428 are formed in a taper shape spreading toward the bottom. When grooves are formed in the protrusions 432 as described above, the chemical liquid is easily held by the protrusions 432, and more chemical liquid can be supplied to the support plate 21 side. Although the groove formed in the protrusion 432 extends downward as described above, the direction is not particularly limited as long as it is a groove toward the support plate 21. Moreover, the groove | channel similar to the protrusion part 432 can also be formed in the inner wall surface of the 1st surrounding wall 431 arrange | positioned at the rim | limb side among the surrounding walls mentioned above, and the inner wall surface of the outflow hole 428. By doing so, the discharge of the chemical liquid is accelerated, and the chemical liquid can be smoothly supplied to the support plate 21 or the protrusion 432.

  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 1st surrounding wall 431 and the protrusion part 432, and moves on 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 running 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 outflow hole 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. Moreover, a part of running water passes through the through-hole 2111 formed in the support plate 21, and returns to the toilet from the bottom surface 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. 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 passage 427 extends horizontally, the water flowing upward through the first peripheral wall 431 and the protrusion 432 once passes through the extension passage 427 extending horizontally and then further extends vertically. If it does not pass through 426, 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.

  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.

  As described above, according to the present embodiment, in the support plate 21, the pair of through holes 2111 are formed on both sides immediately below the outflow hole 428. Therefore, when the apparatus is attached to the rim while being inclined, for example, even if the chemical liquid flows on the support plate 21 on the side opposite to the rim, the chemical liquid is discharged from the through hole 2111 to the outside of the apparatus. That is, since a chemical | medical solution flows into a toilet bowl, it can be made to contact running water. Therefore, even when the apparatus is not attached to the rim at a desired angle, the chemical solution can be brought into contact with running water, and a desired aroma and cleaning effect can be obtained.

  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, if the through-hole 2111 is formed on the support plate 21, it is possible to discharge the chemical solution to the outside through the through-hole 2111 and prevent it from solidifying on the support plate 21. can do.

  In addition, since the shielding wall 2112 is provided between the position directly below the outflow hole 428 and the through hole 2111, only the chemical solution that has passed through the shielding wall 2112 flows out of the through hole 2111. This chemical solution remains on the support plate 21. Therefore, it is possible to prevent the chemical solution from being excessively discharged from the through-hole 2111, and the chemical solution on the support plate 21 is exposed by the flowing water. In addition, it is preferable that the shielding wall 2112 is 1-5 mm in height, for example. The reason is as follows. If it is 1 mm or less, the effect of the shielding wall 2112 may not be sufficiently exhibited when the inclination at the time of attachment is extremely severe. On the other hand, when the thickness is 5 mm or more, the volume of the liquid pool portion due to the shielding wall becomes too large, and there may be a case where the effect of dropping the liquid over the shielding wall 2112 cannot be sufficiently exerted when tilted as described above. Furthermore, the container may become too large.

  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 position of the through hole 2111 on the support plate 21 is not particularly limited as long as it is provided in the vicinity of the position immediately below the outflow hole 428 or on the side opposite to the rim from that position. Further, the shape and number of the through holes 2111 are not particularly limited. The shape, the number, and the position of the shielding wall 2112 are not particularly limited as long as they are formed so as to partition the position immediately below the outflow hole 428 and the through hole 2111.

Further, the support plate may be configured as shown in FIG. FIG. 9 is a plan view of the support plate 21. As shown in the figure, in this example, regulation walls 29 extending in the width direction of the support plate 21 are provided on both sides of the support column 24 formed on the support plate 21. The regulation wall 29 extends from both sides of the support column 24 toward both ends of the base 211 of the support plate 21 and extends so as to form a slight gap 28 from both ends. Thereby, since the flow path of the chemical solution supplied from the outflow hole 428 to the support plate 21 via the protrusion 432 is regulated by the regulation wall 29, the chemical solution passes through the gap 28 and moves the support plate 21. It flows to the part 212 side. Thus, since the flow path of the chemical liquid toward the rim side is regulated, it is possible to prevent the chemical liquid from flowing out excessively. As a result, the chemical solution can be prevented from being used up early. The number and position of the restriction walls 29 are not particularly limited, and may be arranged so that a part of the flow path of the chemical solution can be restricted.
Further, the support plate 21 does not necessarily have to be formed in a plate shape, as long as a surface for receiving a chemical solution is formed.
