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 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.

  By the way, since the above chemical | medical solution supply apparatus is attached inside the rim of a toilet bowl, the thing as small as possible is preferable. In accordance with this, the chemical container is also reduced, but in this case, in order to make it difficult for the chemical liquid to be discharged at one time, it is common to use a container having a high viscosity. However, there is a problem that a high-viscosity chemical solution is clogged or difficult to discharge. In particular, when the temperature is cold, the chemical solution may further increase in viscosity. In addition, a device of the type that is attached to the inside of the rim may not be attached at an intended angle depending on the shape of the toilet bowl, and it may be difficult to expose the chemical solution by running water. Therefore, it is preferable to discharge the chemical solution from the chemical solution container to the outside as much as possible so that the chemical solution can be exposed to whatever angle the flowing water flows.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a chemical solution supply apparatus that can smoothly discharge a chemical solution from a chemical solution container to the outside.

  The present invention is a chemical solution supply device attached to a toilet rim in a flush toilet, containing a chemical solution, having a chemical solution discharge port, connected to the discharge port, the chemical solution in the chemical solution container A chemical solution discharge mechanism that leads to the outside, a support member that supports the chemical solution discharged from the chemical solution discharge mechanism so as to be in contact with running water flowing in the toilet, and the chemical solution container, the drug discharge mechanism, and the support member A hanging member for hanging on the rim, wherein the chemical solution discharge mechanism has an outflow passage that opens toward the support member and discharges the chemical solution, and is at least part of the inner wall surface of the outflow passage In addition, it has a tapered surface whose inner diameter becomes larger toward the downstream side of the outflow path.

  According to this structure, the taper surface where an internal diameter becomes large is formed in the inner wall face of the outflow path which supplies a chemical | medical solution toward a support member toward downstream. That is, since the flow path of the chemical liquid discharged from the outflow path is widened, the resistance received by the chemical liquid is reduced, and the chemical liquid is easily discharged. Further, since the flow path of the chemical solution gradually expands, the action of the surface tension is weakened, and this also facilitates the discharge of the chemical solution. Therefore, the chemical liquid does not stay on the periphery of the outflow hole, and the chemical liquid can be smoothly supplied onto the support member. In addition, the taper surface should just be formed in at least one part around the axis | shaft of the inner wall face of an outflow channel. Further, a tapered surface can be formed on at least a part of the discharge direction of the chemical solution.

  The “outflow passage” in the present invention refers to a passage until the chemical liquid is discharged to the outside. When an outflow hole through which the chemical liquid is discharged is formed, the passage leading to this outflow hole is the outflow passage. Yes, as will be described later, when a peripheral wall is provided around the opening periphery of the outflow hole, the outflow path extends to the downstream end of the peripheral wall.

  In addition, as described above, the tapered surface may be formed in a part of the discharge direction of the outflow passage, but at least the outflow passage opening so that the resistance becomes the smallest at the most downstream end of the outflow passage. It is preferable that it is formed toward the upstream side of the outflow path from the peripheral edge. Further, the “tapered surface” does not necessarily have to be a smooth surface, and may be formed so that the inner diameter increases toward the bottom as a whole even if there are irregularities on the surface.

  The outflow passage can be variously configured, for example, an outflow hole that discharges the chemical liquid from the chemical liquid discharge mechanism, and a peripheral wall that continues to the outflow hole and surrounds at least a part thereof.

  At this time, the peripheral wall can be provided at least on the side opposite to the rim side. According to this configuration, since the peripheral wall is provided on the side of the outflow hole that discharges the chemical liquid on the side opposite to the rim side, even if the device is disposed at an angle, the chemical liquid is rim sided by the peripheral wall. Can be prevented from flowing to the opposite side. Accordingly, the chemical liquid can easily flow to the rim side, and the chemical liquid can be appropriately supplied onto the support member.

  Here, when the peripheral wall is further provided on the rim side, at least one continuous with the peripheral wall, supplied with the chemical liquid discharged from the outflow passage, protrudes to the support member side, and extends in the surface direction of the support member. A ridge can be further provided. According to this configuration, the chemical liquid discharged from the outflow hole is configured to be supplied to at least one protrusion extending in the surface direction of the support member via the peripheral wall. It spreads in the surface direction of the support member. Therefore, the chemical solution can be reliably spread over a wide range with a simple structure. Moreover, a some groove | channel can be formed in a protrusion part. When the groove is formed in the ridge, the chemical liquid is easily held by the ridge, and more chemical liquid can be supplied to the support member side. Here, the direction of the groove can be various directions. For example, the groove can be formed so as to face downward. Here, “downward” means, for example, a vertically downward direction or a direction extending obliquely downward toward the rim side. Thereby, the downward flow of the chemical solution is accelerated, and a large amount of the chemical solution can be supplied to the support member side. Moreover, such a groove | channel can be provided in at least one part of the inner wall face of an outflow channel. For example, it can be provided on the outflow hole or the inner wall surface of the peripheral wall. At this time, the position for providing the groove is arbitrary, such as providing the groove only on the tapered surface.

  In addition, a protrusion part can also be directly provided in the vicinity of an outflow path so that the chemical | medical solution discharged | emitted from the outflow path may be supplied instead of continuing with a surrounding wall.

  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.

  In addition, the chemical solution discharge mechanism can be provided with a guide path that guides the chemical solution downward from the chemical solution container side, and at least one extension passage that communicates with the guide path and extends in a substantially horizontal direction.

  According to this configuration, 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 support member. Therefore, the flowing water that has flowed onto the support member enters the outflow hole above the support member, passes through the extension path that extends horizontally, and does not reach the drug solution container unless it passes through the guide path that extends further upward. Accordingly, since the horizontally extending path is arranged in the upward path from the support member to the chemical liquid container, it becomes difficult for water to enter, and as a result, the inflow of flowing water into the chemical liquid container is surely prevented. be able to.

  According to the chemical solution supply apparatus according to the present invention, the chemical solution can be smoothly discharged from the chemical solution container to the outside.

  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 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 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. 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 in the groove 413. 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. 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 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.

  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. 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 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. 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 first and second peripheral walls 431 and 435 are provided so as to surround the outflow hole 428, and the inner diameter increases as the inner wall surfaces of these peripheral walls go downward. Is formed. Therefore, the flow path of the chemical liquid discharged from the outflow hole 428 is widened, so that the resistance received by the chemical liquid is reduced, and the chemical liquid is easily discharged. Further, since the flow path of the chemical solution gradually expands, the action of the surface tension is weakened, and this also facilitates the discharge of the chemical solution. Therefore, it is possible to prevent the chemical liquid from staying at the periphery of the outflow hole 428 and causing the liquid clogging, and to smoothly supply the chemical liquid onto the support plate 21. In addition, since a plurality of grooves are formed in the protrusion 432, it is easy to hold the chemical solution, and thereby more chemical solution can be supplied to the support plate 21.

  Moreover, in the said embodiment, the flowing water which flowed in in the apparatus is prevented from flowing in into the chemical | medical 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 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. 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.

  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, in the above embodiment, the peripheral walls 431 and 435 are provided so as to surround the front and rear of the outflow hole 428. However, the peripheral wall may not surround the entire periphery of the outflow hole 428, and a part of the periphery of the outflow hole 428. A peripheral wall can also be provided. And the inner wall surface of a surrounding wall should just be formed so that it may spread as it goes down in a taper shape. In particular, it is advantageous to provide the peripheral wall on the rear side of the outflow hole 428, that is, on the side opposite to the rim side, because the chemical liquid can be prevented from flowing out to the side opposite to the rim side.

  Further, the tapered surface does not need to be provided on the entire peripheral wall from the upper end portion to the lower end portion of the peripheral walls 431 and 435 as in the above embodiment. For example, as shown in FIG. Part.

  Moreover, in the said embodiment, although the surrounding wall was provided around the outflow hole 428, a surrounding surface is not provided but a taper surface can also be provided in the inner wall face of the outflow hole 428 as shown in FIG. In this case, the protrusion 432 may extend from the vicinity of the outflow hole. The taper of the inner wall surface of the outflow hole 428 may be part of the axial direction as shown in FIG. 10, or may be formed over the entire axial direction. However, the tapered surface is preferably formed upward from the lower end of the outflow hole 428 or the peripheral walls 431 and 435 so that the resistance becomes the smallest at the lowest end of the flow path.

  Moreover, in the said embodiment, although the downward groove | channel is formed in the protruding part 432, if it is a groove | channel which goes to the support plate 21, the direction will not be specifically limited. 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 solution is accelerated, and the chemical solution can be smoothly supplied by the support plate 21 or the protrusion 432.

  In addition, it is preferable to make the 2nd surrounding wall 435 mentioned above into the height of 1-10 mm to a perpendicular direction, for example. This is because if the apparatus is mounted with an inclination of less than 1 mm, the chemical liquid cannot be prevented from flowing out if the inclination is too large. On the other hand, if it is larger than 10 mm, the container may become large. The second peripheral wall 435 can have various shapes. For example, if the second peripheral wall 435 has a polygonal cross section having a sharp corner, the chemical solution can be easily held. Further, the shape of the first peripheral wall 431 is not particularly limited, but it is sufficient that a vertically downward portion is provided so that the chemical solution can be supplied to the protruding portion 432.

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

  The support plate can also be configured as shown in FIG. FIG. 11 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.
