Description

  The present invention relates to a chemical solution supply apparatus that supplies a chemical solution to a liquid such as water that flows intermittently.For example, the chemical solution supply device is installed in a water-washing tray for hand-washing provided in an upper portion of a water storage tank of a flush toilet, or on a toilet rim. The present invention relates to a chemical liquid supply device that is attached and supplies chemical liquid for fragrance, deodorization, and washing to water for washing.

  As this kind of chemical solution supply device, for example, as shown in the examples of FIGS. 21 to 23 or the examples of FIGS. 24 to 26, a chemical solution container 100 that stores the chemical solution, and a cup shape that supports the chemical solution container 100. And a support member 101 of the type that is installed in a water tray in the upper part of the water storage tank so that the guide member 102 provided in the lower part of the support body 101 comes into contact with the water flowing into the water storage tank has been proposed. (For example, see Patent Documents 1 and 2).

  As shown in FIG. 27, the chemical solution container 100 includes a chemical solution storage unit 100A capable of storing a chemical solution, and an end surface (lower end surface in FIG. 27) of the chemical solution storage unit 100A has a discharge port 100B for discharging the chemical solution. Is provided. The support body 101 has an opening in the upper part, and one end portion 100C (lower end portion in FIG. 27) recessed inside the chemical solution storage portion 100A is fitted into an opening edge (upper edge) 113A at the upper end of the side surface portion 113. It has become so.

  Further, the support body 101 includes a cover member 105 that is detachably attached to the support body 101, and the cover member 105 includes a discharge member 103 that is connected to the discharge port 100 </ b> B of the chemical solution container 100. The chemical solution in the chemical solution container 100 is supplied from the connecting portion 110 of the discharge member 103 through the narrow tube portion 111 to the guide member 102 from the lower through hole 104. The support 101 is provided with an adjustment mechanism 112 that adjusts the amount of the chemical liquid discharged from the chemical liquid container 100. This adjustment mechanism 112 prevents excessive outflow or reverse flow of the chemical solution from the chemical solution container 100 to the guide member 102 even if the internal pressure of the chemical solution container 100 changes when the temperature of the chemical solution container 100 changes due to contact with water or the like. The buffer chamber 106 that can store the chemical solution defined between the support 101 and the cover member 105, the air circulation hole 107 that can flow air into the buffer chamber 106, and the buffer A communication hole 108 for communicating the chamber 106 and the discharge member 103 is provided.

  The chemical solution supply apparatus having the above configuration operates as follows. That is, when the temperature rises and the pressure in the chemical solution container 100 increases, the chemical solution in the chemical solution container 100 flows out from the communication hole 108 and flows into the buffer chamber 106. On the other hand, when the temperature decreases and the pressure in the chemical solution container 100 decreases, the chemical solution in the buffer chamber 106 is drawn back into the chemical solution container 100 through the communication hole 108. By such an action, even if the temperature change is repeated, the chemical liquid can be prevented from flowing out of the chemical liquid supply device. In particular, the temperature change of the chemical solution container 100 occurs both due to the change in the room temperature and the contact with the flowing water supplied to the water supply tray, and thus preventing the wasteful discharge of the chemical solution enables stable supply of the chemical solution. It is important to do. As described above, the chemical solution supply apparatus having the above-described configuration is provided with the buffer chamber 106, thereby preventing an excessive outflow of the chemical solution. As a result, the chemical solution can be discharged from the chemical solution container 100 in an accurate amount. , Stable supply can be realized.

  The chemical solution supply apparatus having the above-described configuration is used by being placed below the water supply pipe on the water supply tray after the chemical solution container 100 is fitted to the support 101 and assembled. In this use, when water falls from the water supply pipe onto the chemical solution container 100, the water flows down along the surface of the chemical solution container 100 and is transmitted to the fitting portion T between the chemical solution container 100 and the support 101. Here, as shown in FIGS. 23 and 26, the upper end edge 113 </ b> A of the side surface 113 that fits with the chemical solution container 100 of the support 101 is from the outside to the inside so as to follow the outer shape of the lower end portion 100 </ b> C of the chemical solution container 100. It is formed in the inclined surface which inclines low toward. Therefore, the water transmitted to the fitting portion T flows between the chemical solution container 100 and the upper end edge 113 </ b> A of the supporting member 101 that can be generated in the fitting portion T, rather than flowing down the outer surface of the side surface portion 113 of the supporting member 101. There is a risk of being guided from the gap to the inclined surface of the upper edge 113 </ b> A and entering the support body 101. When water enters the support 101, the water travels down the lower end surface of the chemical solution container 100 to the buffer chamber 106 near the center of the support 101 and then falls, so that the water that has flowed down is stored in the buffer chamber 106. There is a risk of entering the buffer chamber 106 from the upper air circulation hole 107. When water enters the buffer chamber 106, the chemical solution in the buffer chamber 106 is diluted by the water, and the diluted chemical solution is absorbed into the chemical solution container 100 due to a temperature change. As a result, the chemical solution in the chemical solution container 100 is diluted. Will be. This not only prevents the medicinal effect due to the appropriate amount of the chemical solution, but also lowers the original viscosity depending on the chemical solution, and may flow out excessively from the discharge port of the chemical solution container 100 and impair stable supply.

  Such a problem is a problem that may occur not only in the type installed in the water supply tray at the upper part of the water storage tank but also in the chemical solution supply apparatus of the type attached to the rim of the toilet bowl.

  The present invention has been made paying attention to the above-described problem, and can prevent fluid such as water from entering the support body from the fitting portion between the chemical solution container and the support body, and stably supply the chemical liquid. It is an object of the present invention to provide a chemical solution supply device that can handle the above.

  An object of the present invention is to provide a chemical solution supply apparatus that includes a chemical solution container that contains a chemical solution therein and a cup-shaped support that supports the chemical solution container, and is assembled by fitting the chemical solution container to the support. The upper end edge of the support body includes an inclined surface portion that is inclined downward toward the outer side of the support body, and the top portion of the inclined surface portion abuts on the surface of the chemical container fitted to the support body. Alternatively, it is achieved by a chemical supply device that is in close proximity.

  In the chemical liquid supply apparatus having the above configuration, when a part of fluid such as water that flows intermittently adheres to the chemical liquid container, it flows down along the surface of the chemical liquid container and is transmitted to the fitting portion between the chemical liquid container and the support. The fluid may enter the support body from the gap between the chemical solution container and the support body that may occur in the fitting portion. However, in the chemical solution supply apparatus having the above configuration, the upper end edge of the support is formed on an inclined surface that is inclined low toward the outside of the support, and the top of the inclined surface is in contact with or close to the surface of the chemical solution container. Therefore, after the fluid transmitted to the fitting portion is blocked at the top of the upper edge of the support, it is guided to the outside of the support by the inclined surface rather than the support, and along the outer peripheral surface of the support. You are prompted to flow downward. In this way, water that has flowed down the surface of the chemical solution container can be prevented from entering the support body from the fitting portion, and therefore, for example, fluid can be prevented from entering the buffer chamber provided in the support body. As a result, the chemical solution stored in the buffer chamber can be prevented from being diluted, and the concentration of the chemical solution discharged from the chemical solution container can be maintained appropriately.

  In a preferred embodiment of the present invention, an angle formed by a vertical surface of a plane connecting both ends of the inclined surface portion is 5 ° to 75 °. According to this embodiment, the fluid that has flowed down the surface of the chemical container and transmitted to the fitting portion of the chemical container and the support is effectively guided out of the support by the inclined surface portion of the upper edge of the support, Since it flows down along the outer peripheral surface of a support body, it can prevent more effectively that water permeates into a support body from the said fitting part. The front inclined surface portion may be formed in a convex curved surface having a circular arc shape in cross section, or may be formed in a flat surface having a linear shape in cross section. In addition, when the inclined surface part is formed in the flat surface of a cross-sectional view linear shape, the flat surface of the said inclined surface part surface turns into the said plane. Further, the inclined surface portion may be formed of a concave curved surface having a circular arc shape in cross section or a curved surface having a polygonal shape in cross section.

The top of the upper edge of the support is in contact with or close to the support.

  According to this embodiment, the overhanging portion of the chemical solution container functions as a ridge that covers the upper part of the fitting portion of the chemical solution container and the support, so that the fluid flowing down the surface of the chemical solution container may reach the fitting portion. It is regulated in advance. Then, the fluid that has reached the fitting portion is prevented from entering the support body from the fitting portion by the action of the top portion and the inclined surface portion of the upper end edge of the supporting member. As described above, by providing the overhanging portion in the chemical liquid container, it is possible to more effectively prevent the water flowing down the surface of the chemical liquid container from entering the support body.

  In a further preferred embodiment of the present invention, the chemical device further comprises a hanging member for hanging on a toilet rim of a flush toilet, and the chemical solution discharged from the chemical solution container is directly supplied into the toilet. Or it is the chemical | medical solution supply apparatus comprised so that it might supply in the said toilet bowl by exposing by the flowing water supplied in the said toilet bowl at the time of washing.

  In still another preferred embodiment of the present invention, the chemical liquid device is arranged such that the support is disposed in a water supply tray above the water storage tank of a flush toilet, and the chemical liquid discharged from the chemical liquid container is directly put into the water storage tank. The chemical supply device is configured to supply or supply into the water storage tank by being exposed to running water supplied to the water supply tray during washing.

  According to the chemical solution supply apparatus of the present invention, it is possible to prevent a fluid such as water from entering the support body from the fitting portion between the chemical solution container and the support member. Therefore, it is possible to prevent water from entering the buffer chamber and diluting the chemical solution, and the chemical solution can be supplied stably.

  Hereinafter, the actual form of the present invention will be described with reference to the accompanying drawings. 1 and 2 show the appearance of a chemical solution supply apparatus 1 according to an embodiment of the present invention, and FIG. 3 shows a state where the chemical solution supply apparatus 1 of FIGS. 1 and 2 is disassembled. In addition, the chemical | medical solution supply apparatus 1 of the example of illustration has mentioned the thing of the type installed in the water receiving tray (not shown) for the hand-washing of the upper part of the water storage tank in a flush toilet.

  The chemical solution supply apparatus 1 includes a chemical solution container 2 that stores chemical solutions for aroma, deodorization, and toilet cleaning, and a cup-shaped support 3 that supports the chemical solution container 2. The support 3 includes a cover member 4 (shown in FIG. 7) that is detachably attached to the support 3. In addition, the support 3 includes a guide member 5 in the lower portion for guiding the chemical liquid discharged from the chemical liquid container 2 to a position in contact with the intermittently flowing liquid outside the support 3. The chemical solution supply apparatus 1 is installed such that the guide member 5 and the long leg portion 36 of the support 3 are inserted into a drain outlet (not shown) of the water supply tray.

  The chemical solution container 2 includes a chemical solution storage unit 20 that can store a chemical solution, and a discharge port 21 for discharging the chemical solution is provided on an end surface (lower end surface in FIG. 3) of the chemical solution storage unit 20. The chemical solution container 2 is partially or entirely made of a transparent or translucent material, and the remaining amount of the chemical solution can be confirmed from the outside. A cap 22 is put on the discharge port 21.

  The support 3 is made of a synthetic resin such as polyethylene, polypropylene, polyethylene terephthalate, and has an opening in the upper portion and is formed in a substantially elliptical shape in plan view, as shown in FIGS. The support body 3 includes a bottom surface portion 30 and a side surface portion 31, and one end portion 23 (the lower end portion in FIG. 3) that is recessed inside the chemical solution storage portion 20 is fitted to the upper end edge 39 of the side surface portion 31. It is like that.

  Two long legs 36 and four short legs 38 arranged around the long legs 36 are provided upright on the lower surface of the bottom surface 30. The long leg portion 36 can be inserted into the water outlet of the water supply tray. The short leg portion 38 supports the support 3 substantially horizontally on the water supply tray in a state where the guide member 5 and the long leg portion 36 are inserted into the drainage port. A substantially rectangular frame-shaped peripheral wall (hereinafter referred to as “in this embodiment”) is fitted on the outer surface of a peripheral wall (hereinafter referred to as “inner wall” in the present embodiment) 41 of a cover member 4 to be described later. 32) is provided.

  The upper end edge 39 of the side surface portion 31 is inclined downward from the inner side of the support 3 toward the outer side, and an inclined surface portion 31C is formed between the inner side surface 31A and the outer side surface 31B of the side surface portion 31. . In this embodiment, as shown in FIG. 12A, the inclined surface portion 31C is formed in a convex curved surface having a circular arc shape (or a substantially arc shape) in sectional view, that is, a convex curved surface. The angle of the tangent line 1 with respect to the vertical plane C extending straight downward from the top portion 31D is 90 ° or less.

  When the chemical liquid container 2 is fitted to the support 3, the top part 31 </ b> D of the inclined surface part 31 </ b> C comes into contact with or approaches the surface of the chemical liquid container 2 to be fitted. Therefore, the top portion 31D of the inclined surface portion 31C is a boundary between the chemical liquid container 2 and the support body 3 outside the support body 3. The inner side surface 31A of the support 3 on the inner side of the top portion 31D extends downward without being along the outer shape of the chemical liquid container 2, and an inclined surface portion 31C that is inclined lower is provided outside the top portion 31D. Therefore, water that has fallen onto the chemical liquid container 2 from a water supply pipe (not shown) on the water supply tray flows down along the surface of the chemical liquid container 2 to the fitting portion T between the chemical liquid container 2 and the support 3. Even when the water is transmitted, the water is blocked by the top portion 31D of the upper end edge 39 of the support 3 and then guided to the outside of the support 3 by the inclined surface portion 31C rather than inside the support 3, so that the outer side surface 31B of the side surface portion 31. Is urged to flow downward along. Therefore, since the water that has flowed down the surface of the chemical solution container 2 is prevented from entering the support 3 from the fitting portion T, it is possible to prevent water from entering the buffer chamber 60 described later.

  When the slope of the inclined surface portion 31C is gentle, the water transmitted to the fitting portion T of the chemical solution container 2 and the support 3 is not easily flown toward the outer side surface 31B of the side surface portion 31 by the inclined surface portion 31C. Become. Therefore, the angle α formed between the plane V connecting the both ends of the inclined surface portion 31C and the vertical plane C is desirably 75 ° or less, and more desirably 60 ° or less. On the other hand, if the inclination of the inclined surface portion 31C is too steep, the top portion 31D becomes sharp and dangerous at the time of use, or the side surface portion 31 becomes too thin and the strength of the upper edge 39 is lowered. Is preferably 5 ° or more, more preferably 10 ° or more.

  In the present embodiment, the inclined surface portion 31C is formed in a convex curved surface, but may be formed in a concave curved surface that curves in a concave shape as shown in FIG. Further, in both FIGS. 12A and 12B, the inclined surface portion 31C does not necessarily have to be smoothly curved, and may be a polygonal curved surface having an angular cross-sectional view.

  Moreover, as shown in FIG.12 (c), 31 C of inclined surface parts may be formed in the flat surface of cross sectional view linear form. In the inclined surface portion 31C having the shape of FIG. 12C, if the inclination of the flat surface V connecting the both ends of the inclined surface portion 31C, that is, the flat surface of the inclined surface portion 31C is loose, similarly, the chemical solution container 2 and the support body The water transmitted to the third fitting portion T is urged by the inclined surface portion 31 </ b> C and hardly flows toward the outer side surface 31 </ b> B of the side surface portion 31. Therefore, the angle θ between the inclined surface portion 31C and the vertical surface C is desirably 75 ° or less, and more desirably 60 ° or less. On the other hand, if the inclination of the flat surface of the inclined surface portion 31C is too steep, the top portion 31D becomes sharp and is dangerous at the time of use, or the side surface portion 31 becomes too thin and the strength of the upper edge 39 is reduced. The angle θ is preferably 5 ° or more, and more preferably 10 ° or more.

  In the example shown in FIG. 12, the upper end edge 39 of the support 3 is composed of only the inclined surface portion 31 </ b> C, and the inclined surface portion 31 </ b> C is continuous with the inner surface 31 </ b> A of the side surface portion 31. ), A horizontal intermediate surface portion 31E may be interposed between the inclined surface portion 31C and the inner surface 31A of the side surface portion 31. Also in the embodiment of FIG. 13 (a), the top portion 31D of the inclined surface portion 31C (that is, the connection portion between the inclined surface portion 31C and the intermediate surface portion 31E) abuts on the surface of the chemical liquid container 2 fitted to the support 3 or As long as it is located close to the boundary between the chemical liquid container 2 and the support 3 outside the support 3, the top portion 31 </ b> D and the inclined surface portion of the upper end edge 39 of the support 3 as in the above-described embodiment. By the action of 31C, it is possible to prevent water flowing down the surface of the chemical solution container 2 from entering the support 3 from the fitting portion T. Therefore, as a result of preventing water from entering the buffer chamber 60, the chemical solution stored in the buffer chamber 60 can be prevented from being diluted. As shown in FIG. 13B, the intermediate surface portion 31 </ b> E is transmitted to the fitting portion T between the chemical solution container 2 and the support 3 when it is an inclined surface along the outer shape of the chemical solution container 2. This is not preferable because water is guided not by the inclined surface portion 31C but by the intermediate surface portion 31E and may enter the support 3.

  As shown in FIGS. 7 to 10, the cover member 4 is formed in a box shape having an open lower end, and has an upper surface portion 40 having a substantially rectangular shape in plan view and a substantially rectangular frame shape hanging from the upper surface portion 40.

And below the bottom hole 34, the guide member 5 which guides the chemical | medical solution discharged | emitted from the thin tube part 42b below is provided. The guide member 5 is integrally provided on the lower surface of the bottom surface portion 30, and a fitting protrusion 50 that fits into the narrow tube portion 42 b of the discharge member 42 is integrally provided on the upper end portion of the guide member 5. . A vertical groove 51 extending from the upper end to the lower end is formed on the outer surface of the fitting protrusion 50, and a chemical solution outlet path is formed between the vertical groove 51 and the inner peripheral surface of the narrow tube portion 42 b. . The cross-sectional shape of the vertical groove 51 can be various shapes such as a semicircular shape and a square shape such as a triangle or a quadrangle. Moreover, it is desirable that the cross-sectional dimensions be such that the chemical solution can be led out along the lead-out path by capillary action. Around the bottom hole 34, an annular portion 35 that is fitted to the outside of the thin tube portion 42 b is provided upright in order to securely hold the fitting state of the thin tube portion 42 b and the fitting protrusion 50.

  The guide member 5 is formed in a plate shape, and the upper end portion is in contact with the lower end of the narrow tube portion 42b. A large number of fine grooves 52 extending in the vertical direction are formed on the front and back plate surfaces of the guide member 5. The guide member 5 is located between the two long legs 36 and is inserted into the drain outlet of the water supply tray together with the long legs 36. However, the guide member 5 is formed slightly shorter than the long leg portion 36, and only the lower end portion thereof can be inserted into the drain outlet. A shielding member 37 is provided between the guide member 5 and the long leg portion 36. The shielding member 37 is formed to be shorter than the guide member 5, the long leg portion 36 positions the support 3 at the drain outlet, and the guide member 5 comes into contact with the water flowing down to the drain outlet, whereby the guide member 5. The upper chemical solution is washed away by water and flows into the water storage tank. On the other hand, the shielding member 37 restricts the flowing-down water from flowing back into the support 3 from the lead-out path.

  An opening 33 </ b> A for diffusing the aromatic component of the chemical solution to the outside is formed in the side surface portion 31 of the support 3. In addition, an opening 33 </ b> B is formed at the outer position of the outer wall 32 of the bottom surface portion 30 to discharge the water to the outside when the water supplied to the water supply tray enters the support 3. .

  The support 3 is assembled by fitting the inner wall 41 of the cover member 4 inside the outer wall 32 of the bottom surface 30. Accordingly, as shown in FIG. 11, the support 3 has a region (bottom wall) surrounded by the outer wall 32 of the bottom surface portion 30, the outer wall 32, and the inner wall 41 ( A buffer chamber 60 surrounded by the side wall) and the upper surface portion 40 (upper wall) of the cover member 4 is formed. The buffer chamber 60 is partitioned from the thin tube portion 42b and has a space in which a chemical solution can be stored. In FIG. 11, the alternate long and short dash line indicates a part of the container 2 that is fitted to the support 3.

  The buffer chamber 60 constitutes an adjustment mechanism 6 that adjusts the amount of the chemical solution discharged from the chemical solution container 2, and the adjustment mechanism 6 provides air to the buffer chamber 60, the communication hole 61 described above, and the buffer chamber 60. It is comprised by the air circulation hole 62 which flows in. The communication hole 61 can introduce a part of the chemical liquid discharged from the chemical liquid container 2 to the connection portion 42 a of the discharge member 42 into the buffer chamber 60.

  The air circulation hole 62 is provided in the side wall of the buffer chamber 60 in this embodiment. While the upper end of the outer wall 32 of the support 3 is cut out in a concave shape, a through hole 63 is formed in the outer wall 32, while the inner wall 41 of the cover member 4 has a lower end from its upper end. A slit 64 extending in the vertical direction is formed. The slit 64 is formed at a position corresponding to the through hole 63 of the outer wall 32 of the support 3, and the cover member 4 is attached to the support 3 so that the through hole 63 and the slit 64 coincide with each other. The air circulation hole 62 is formed.

  In the present embodiment, the air circulation hole 62 is provided in the width central portion of two opposing sides of the side wall (the outer wall 32 and the inner wall 41) of the buffer chamber 60 that is substantially rectangular in plan view. The arrangement of the flow holes 62 is not necessarily limited to this, and can be provided at any position on the side wall of the buffer chamber 60. In the present embodiment, the air circulation hole 62 is provided at the upper end of the side wall of the buffer chamber 60, but it can also be provided at a position below the upper end. However, it is not preferable that the water supply tray is arranged too low, because when the water supplied to the water supply tray enters the support 3, the water may enter the buffer chamber 60 through the air circulation hole 62. . In the present embodiment, the air flow holes 62 are formed by providing the longitudinal slits 64 in the inner wall 41. However, the inner wall 41 is provided with through holes in the same manner as the outer wall 32, and the through holes are formed between the through holes. May be formed so that the air circulation holes 62 are formed. Moreover, in this embodiment, although the air circulation hole 62 has faced the horizontal direction, you may form it so that it may become downward (diagonally downward) rather than a horizontal direction.

  The adjustment mechanism 6 described above acts as follows on the temperature change of the chemical solution container 2. For example, when the temperature rises and the chemical liquid container 2 is warmed, the air in the chemical liquid container 2 expands and the chemical liquid container 2 has a positive pressure. In this case, the chemical solution in the chemical solution container 2 is pushed out and discharged from the discharge port 21, but the discharged chemical solution flows into the lead-out path from the thin tube portion 42 b and also flows into the buffer chamber 60 through the communication hole 61. Therefore, it is possible to prevent the chemical liquid from flowing out excessively into the outlet path.

  On the other hand, when the temperature of the chemical solution container 2 is lowered by being cooled by running water or the like, the air in the chemical solution container 2 contracts and the inside of the chemical solution container 2 becomes negative pressure. In this case, the chemical solution in the buffer chamber 60 that is at atmospheric pressure or indoor pressure due to the action of the air circulation hole 62 is sucked into the chemical solution container 2 through the communication hole 61. Therefore, it is suppressed that the water on the guide member 5 or the diluted chemical solution is returned to the chemical solution container 2 side through the thin tube portion 42b. Further, the discharge of the chemical liquid is prevented from being restricted by the negative pressure in the chemical liquid container 2. Thus, even when a pressure change occurs in the chemical solution container 2 due to a temperature change, the adjustment mechanism 6 causes the chemical solution to flow between the chemical solution container 2 and the buffer chamber 60. Can be prevented from flowing out excessively or being restricted from flowing out.

  In the chemical solution supply apparatus 1 having the above-described configuration, after the outer wall 32 of the support 3 is fitted to the outer side of the inner wall 41 of the cover member 4 to form the buffer chamber 60, the discharge member 42 extending upward from the cover member 4. The connecting portion 42a is assembled by inserting the cap 22 through the outlet 21 of the chemical liquid container 2 and inserting it. And the chemical | medical solution in the chemical | medical solution container 2 flows into the thin tube part 42b from the connection part 42a by the guide member 5 and the long leg part 36 of the support body 3 being inserted in the drain outlet of the water receiving tray of the water tank for flush toilets. Then, it is discharged from the outlet path to the guide member 5, and the chemical solution on the guide member 5 is washed away by the water supplied to the water supply tray at the time of flushing, and flows into the water storage tank from the drain outlet. Note that the chemical solution supply device 1 having the above-described configuration also discharges the chemical solution over time even when the chemical solution on the guide member 5 is not washed away by the water supplied to the water supply tray at the time of flushing. It is also possible to provide a mechanism for supplying the chemical solution directly to the water storage tank.

  At this time, the water that falls from the water supply pipe on the water supply tray onto the chemical liquid container 2 and flows down along the surface of the chemical liquid container 2 is transmitted to the fitting portion T of the chemical liquid container 2 and the support body 3. After being blocked by the top portion 31D of the upper end edge 39 of 3, most of the portion is guided to the outside of the support body 3 rather than inside the support body 3 by being guided by the inclined surface portion 31C on the outer side. It is urged to flow downward along the outer surface 31B. And it flows down the outer side surface 31B of the side part 31, and falls to a water supply tray. As described above, the top portion 31D and the inclined surface portion 31C of the upper end edge 39 of the support 3 prevent the water flowing down the surface of the chemical solution container 2 from entering the support 3 from the fitting portion T. Water can be effectively prevented from entering the buffer chamber 60. Therefore, as a result of preventing the chemical solution stored in the buffer chamber 60 from being diluted, the chemical solution in the chemical solution container 2 is prevented from being diluted due to the return of the chemical solution, and the concentration of the chemical solution discharged from the chemical solution container 2 is maintained appropriately. be able to. In the present embodiment, since the air circulation hole 62 is provided in the upper end portion of the side wall of the buffer chamber 60, water temporarily enters the support 3 and travels along the lower end surface of the chemical solution container 2 to the buffer chamber 60. Even when it flows down, it is difficult to enter the buffer chamber 60 from the air circulation hole 62.
