Description

  The present invention relates to a chemical solution supply device 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 tray for hand washing provided in a water storage tank of a flush toilet, and has aroma, deodorant, and cleaning. It is related with the chemical | medical solution supply apparatus which supplies the chemical | medical solution for washing to the water for washing.

  As this kind of chemical solution supply apparatus, for example, as shown in FIGS. 34 to 36, a chemical solution container 100 for storing a chemical solution and a cup-shaped support body 101 having an opening in the upper part are provided. There has been proposed a type that is installed in a water receiving tray at the top of the water storage tank so that the guide member 102 provided on the water tank contacts the water flowing into the water storage tank (see, for example, Patent Document 1).

  The support body 101 includes a cover member 103 that is detachably mounted on the bottom surface portion 101 </ b> A. The cover member 103 includes a discharge member 104 that is connected to the discharge port 105 of the chemical solution container 100. The chemical solution in the chemical solution container 100 is supplied from the discharge member 104 to the guide member 102. The support body 101 is provided with a buffer chamber 106 between the bottom surface portion 101 </ b> A and the cover member 103 for adjusting the amount of the chemical liquid discharged from the chemical liquid container 100. In the buffer chamber 106, when the temperature of the chemical solution container 100 fluctuates due to contact with water or the like, even if the internal pressure of the container changes, excessive outflow or reverse flow of the chemical solution from the chemical solution container 100 to the guide member 102 is prevented. The buffer chamber 106 is formed with a communication hole (not shown) that allows the buffer chamber 106 and the discharge member 104 to communicate with each other, and an air hole 107 through which air can flow into the buffer chamber 106. ing.

  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, a part of the chemical solution in the chemical solution container 100 flows out from the communication hole 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. By such an action, it is possible to prevent the chemical liquid from being unnecessarily discharged from the chemical liquid supply device even if the temperature change is repeated. In particular, the temperature change of the chemical solution container 100 occurs both due to a change in room temperature and contact with running water supplied to the water supply tray. Therefore, 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 disposed on the drain outlet of the water supply tray after the chemical solution container 100 is turned upside down and attached so that the outer peripheral edge 108 of the chemical solution container 100 is aligned with the opening edge 109 of the support 101. Used. Here, in use, water that has dropped from the water supply pipe onto the chemical liquid container 100 flows down along the surface of the chemical liquid container 100 and travels to the outer peripheral edge 108 of the chemical liquid container 100, and the outer peripheral edge 108 of the chemical liquid container 100 and the support body. There is a risk of entering the support body 101 through an inevitably generated gap O between the opening edge 109 of the 101. The water that has entered the support 101 falls while traveling down the lower surface 110 of the chemical solution container 100 in an inverted state. However, if the entered water travels over the buffer chamber 106 near the center of the support 101 and falls, the water flows down. Water may enter the buffer chamber 106 through the air hole 107 at the top of the buffer chamber 106. 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. If it does so, not only the medicinal effect by the appropriate amount of chemical | medical solution will be prevented, but the original viscosity falls depending on a chemical | medical solution, and it may flow out excessively from the discharge port of the chemical | medical solution container 100, and may impair stable supply.

A cap 23 is detachably placed on the mouth portion 21, and the discharge port 22 is closed by the cap 23 to seal the inside of the chemical solution container 2.

  In the present embodiment, the body portion 20 of the drug solution container 2 is formed in a teardrop shape with one end in the major axis direction of an ellipse sharpened in a plan view. The body portion 20 has a substantially flat upper end surface 25 and lower end surface 26, and a side surface 27 between the upper end surface 25 and the lower end surface 26, and the side surface 27 extends downward from the outer peripheral edge 24. As it goes, it has an upper side surface 27A that spreads radially outward and a lower side surface 27B that narrows radially inward. Here, the outer peripheral edge 24 indicates a line (contour) that forms the outer shape of the body 20 in a plan view. In the present embodiment, the outer peripheral edge 24 is obliquely upward from the front side to the back side in the side view. The body 20 is formed so as to incline toward. Moreover, in this embodiment, the trunk | drum 20 is formed so that the side surface 27 (upper side surface 27A and lower side surface 27B) may have a polygonal shape.

  Next, the support 3 is made of a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate, and has an opening in the upper portion and is formed in a teardrop shape in plan view, as shown in FIGS. . The support 3 includes a bottom surface portion 30 and a side surface portion 31 and a cover member 6 that is detachably attached to the bottom surface portion 30, and an upper end edge of the side surface portion 31 is an opening edge 32 of the upper opening.

  A plurality of openings O1 for diffusing the aromatic component of the chemical solution to the outside are formed in the side surface portion 31 of the support 3. In addition, the side surface 31 is cut off at an upper end obliquely, and the opening edge 32 is a side surface similar to the outer peripheral edge 24 of the chemical liquid container 2 fitted to the opening edge 32 when the chemical liquid container 2 is attached to the support 3. In view, it is inclined obliquely upward from the front side toward the back side.

  On the bottom surface 30 of the support 3, two long legs 33 and four short legs 34 arranged around the long legs 33 protrude from the bottom surface thereof. The long legs 33 can be inserted into the water outlet of the water tray. The short legs 34 support the support 3 substantially horizontally on the water supply tray in a state where the long legs 33 are inserted into the drain outlet of the water supply tray. On the upper surface of the bottom surface portion 30, a peripheral wall (hereinafter referred to as an “outer peripheral wall”) 35 having a substantially rectangular frame shape in plan view superimposed on the outer side of the peripheral wall (hereinafter referred to as “inner peripheral wall”) 61 of the cover member 6. Is provided.

  The cover member 6 includes an upper surface portion 60 having a substantially rectangular shape in plan view, and an inner peripheral wall 61 having a substantially rectangular frame shape that hangs down from the upper surface portion 60, and the inner peripheral wall 61 is disposed outside the bottom surface portion 30 of the support 3. The cover member 6 is attached to the bottom surface portion 30 by being fitted inside the peripheral wall 35. The cover member 6 further includes a surrounding wall 62 having a substantially rectangular frame shape that hangs down outside the inner peripheral wall 61 of the upper surface portion 60. At the lower end of the surrounding wall 62, a pair of plate-like locking pieces 63 extending horizontally are provided at positions facing each other. On the bottom surface 30 of the support 3, a pair of locking claws 36 are provided at positions facing each other. The locking claws 36 are hooked on the corresponding locking pieces 63, so that the cover member 6 is Fixed to the bottom part 30.

  The upper surface portion 60 of the cover member 6 includes a lower step portion 60a having a circular shape in plan view located at the center thereof, and an upper step portion 60b around the lower step portion 60a positioned higher than the lower step portion 60a. A discharge member 64 that is connected to the discharge port 22 of the chemical liquid container 2 and discharges the chemical liquid in the chemical liquid container 2 to the outside is provided at the center position of the lower part 60a.

  The discharge member 64 includes a cylindrical connection portion 64a protruding from the upper surface of the lower step portion 60a, and a cylindrical thin tube portion 64b protruding from the lower surface of the lower step portion 60a and having a smaller diameter than the connection portion 64a. The connection part 64 a has an upper end cut obliquely and is connected to the discharge port 22 of the chemical liquid container 2. The connection portion 64a and the narrow tube portion 64b communicate with each other through a flow hole 64c formed in the lower portion 60a in the connection portion 64a. The inside of the connection portion 64a and the narrow tube portion 64b allows the chemical solution to be discharged from the chemical solution container 2. A chemical solution passage through the guide member 5 is configured. A plurality (three in the illustrated example) of communication holes 65 are formed in the connection portion 64a of the lower portion 60a and around the thin tube portion 64b.

  By attaching the cover member 6 to the bottom surface portion 30 of the support 3, as shown in FIGS. 23 and 24, a buffer chamber 7 having a space in which a chemical solution can be stored is formed. The buffer chamber 7 serves to adjust the amount of the chemical liquid discharged from the chemical liquid container 2. The buffer chamber 7 is partitioned from the thin tube portion 64 b, and a part of the chemical solution discharged from the chemical solution container 2 to the connection portion 64 a is introduced into the buffer chamber 7 through the communication hole 65. The buffer chamber 7 is formed with an air hole 70 through which air flows into the buffer chamber 7.

  The air hole 70 is formed in the side wall of the buffer chamber 7 constituted by the outer peripheral wall 35 and the inner peripheral wall 61. In the present embodiment, through holes 71 are formed in the outer peripheral wall 35 by cutting out the upper end portion of the outer peripheral wall 35 of the support 3 in a concave shape. On the other hand, the inner peripheral wall 61 of the cover member 6 is formed with a slit 72 extending in the vertical direction from the upper end portion to the lower end portion thereof. The slit 72 is formed at a position corresponding to the through hole 71 of the outer peripheral wall 35. By attaching the cover member 6 to the bottom surface 30 and aligning the through hole 71 and the slit 72, the horizontal direction is adjusted. A facing air hole 70 is formed in the side wall of the buffer chamber 7. In the present embodiment, the air holes 70 are respectively formed in the width center portions of two opposite sides of the side wall of the buffer chamber 7.

  The arrangement of the air holes 70 is not necessarily limited to this embodiment, and can be formed at any position on the side wall of the buffer chamber 7. In the present embodiment, the air hole 70 is formed in the upper end portion of the side wall of the buffer chamber 7, but it can also be formed in a position below the upper end portion. However, it is not preferable to dispose it too low, because when the water supplied to the water supply tray enters the support 3, the water may enter the buffer chamber 7 through the air holes 70. In the present embodiment, the air holes 7 are formed by forming the elongated slits 72 in the inner peripheral wall 61 of the cover member 6. However, the inner peripheral wall 61 is provided with a through hole in the same manner as the outer peripheral wall 35. The air holes 70 may be formed by matching the through holes. Further, the air hole 70 may be formed by forming a through hole in the inner peripheral wall 61 and forming a longitudinal slit in the outer peripheral wall 35, and further, a longitudinal slit is formed in both the inner peripheral wall 61 and the outer peripheral wall 35. Thus, the air holes 70 may be formed. In the present embodiment, the air holes 70 face the horizontal direction, but may be formed so as to face downward (obliquely downward) than the horizontal direction. The air holes 70 are not necessarily provided in the side wall of the buffer chamber 7, and may be formed in the upper wall of the buffer chamber 7 (the upper surface portion 60 of the cover member 6).

  The buffer chamber 7 having the above configuration acts as follows on the temperature change of the chemical solution container 2. For example, in FIGS. 7 and 8, when the temperature rises and the chemical solution container 2 is warmed, the air in the chemical solution container 2 expands and the inside of the chemical solution container 2 becomes positive pressure. In this case, the chemical solution in the chemical solution container 2 is pushed out and discharged from the discharge port 23, but the discharged chemical solution is supplied from the discharge member 64 to the guide member 5, and also through the communication hole 65. Also flows. Therefore, it is possible to prevent the chemical solution from being excessively supplied to the guide member 5.

  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 7, which is at atmospheric pressure or indoor pressure due to the action of the air hole 70, is sucked into the chemical solution container 2 through the communication hole 65. Therefore, the water on the guide member 5 or the diluted chemical solution is prevented from returning to the chemical solution container 2 side through the discharge member 64. Further, the discharge of the chemical liquid is prevented from being restricted by the negative pressure in the chemical liquid container 2.

  In this way, even when a pressure change occurs in the chemical solution container 2 due to a temperature change by the buffer chamber 7, the chemical solution flows between the chemical solution container 2 and the buffer chamber 7. Can be prevented from being excessively discharged or restricted.

  Returning to FIGS. 17 to 24, a through-hole 37 having a circular shape in plan view is formed in the bottom surface portion 30 of the support 3 at the center position of the region surrounded by the outer peripheral wall 35. The narrow tube portion 64 b of the discharge member 64 is fitted into the through hole 37.

  A guide member 5 is provided on the lower surface of the bottom surface portion 30 so as to cross the through hole 37. The guide member 5 is a plate-like member that guides the drug solution discharged from the narrow tube portion 64b downward, and a projection 50 that fits into the narrow tube portion 64b is integrally provided on the upper end surface of the guide member 5. Yes. A vertical groove (not shown) extending from the upper end to the lower end is formed on the outer surface of the protrusion 50, and a chemical solution outlet path is formed between the vertical groove and the inner peripheral surface of the narrow tube portion 64b. . The cross-sectional shape of the longitudinal groove can be various shapes such as a semicircular shape and a square shape such as a triangle or a quadrangle, and the cross-sectional dimension of the longitudinal groove is that the chemical solution is led out along the outlet path by capillary action. It is desirable to obtain a degree to be obtained. In addition, an annular protrusion 38 that is fitted to the outside of the thin tube portion 64b is provided around the through hole 37 on the bottom surface portion 30 in order to securely hold the fitting state between the thin tube portion 64b and the protrusion 50. Yes.

  The upper end portion of the guide member 5 is in contact with the lower end of the narrow tube portion 64b. A large number of narrow grooves 51 extending in the vertical direction are formed on the front and back plate surfaces of the guide member 5. The guide member 5 is positioned between the two long legs 33 and is inserted into the drain outlet of the water supply tray together with the long legs 33. However, the guide member 5 is formed slightly shorter than the long legs 33, and only the lower end portion thereof can be inserted into the drain outlet. A shielding member 39 surrounding the guide member 5 is provided between the guide member 5 and the long leg 33 on the lower surface of the bottom surface portion 30 so as to protrude. The shielding member 39 is formed to be shorter than the guide member 5, the long legs 33 position the support 3 at the drain outlet, and the guide member 5 contacts the water flowing down to the drain outlet, so that the guide member 5 The chemical solution is washed away with water and flows into the water storage tank. On the other hand, the shielding member 39 restricts the flowing-down water from flowing back into the support 3.

  A plurality of openings O <b> 2 for discharging water that has entered the inside of the support 3 to the outside are formed at positions outside the outer peripheral wall 35 of the bottom surface portion 30.

  Finally, as shown in FIGS. 25 to 32, the inner lid 4 has an opening at the top and is formed in a teardrop shape in plan view. In this embodiment, the inner lid 4 includes a peripheral wall portion 40 that forms a side surface, and a bottom surface portion 41 that is provided continuously to the lower end edge of the peripheral wall portion 40, and the upper end edge 42 of the peripheral wall portion 40 has an upper opening. It is an opening edge. In use, the peripheral wall portion 40 is a portion facing the lower side surface 27 </ b> B below the outer peripheral edge 24 of the chemical solution container 2, and the bottom surface portion 41 is a portion facing the lower surface 26 of the chemical solution container 2.

  On the lower surface of the bottom surface portion 41, a pair of hanging hooks 43 are provided at positions that are boundary positions with the peripheral wall portion 40 and face each other. A pair of locking projections 44 extending inward are provided at the lower end position of the side surface portion 31 of the support 3 and facing each other, and the locking claws 43 respectively corresponding to the locking projections 44 are provided. By hooking from below, the inner lid 4 is attached to the support 3 and fixed.

  The peripheral wall portion 40 is cut off at an upper end obliquely, and the upper end edge 42 in the side view is the same as the outer peripheral edge 24 of the chemical solution container 2 fitted to the upper end edge 42 when the chemical solution container 2 is attached to the support 3. It is inclined obliquely upward from the front side toward the back side. Further, the peripheral wall portion 40 is formed so that the upper end edge 42 is slightly larger than the outer peripheral edge 24 of the chemical solution container 2. Accordingly, as shown in FIGS. 2 to 4 and 6, in the state in which the inner lid 4 is interposed between the chemical liquid container 2 and the support 3, the upper edge 42 of the inner lid 4 is liquid chemical in a plan view. It protrudes outside the outer peripheral edge 24 of the container 2. Therefore, the water that has fallen from the water supply pipe onto the chemical liquid container 2 during use and has flowed down along the surface of the chemical liquid container 2 to the outer peripheral edge 24 of the chemical liquid container 2 is transferred to the outer peripheral edge 24 and the inner lid 4 ( Even when entering the inside of the chemical solution supply device 1 through the gap inevitably generated between the upper end edge 42 of the peripheral wall portion 40), the water that has entered the chemical solution supply device 1 is not the lower side surface 27B of the chemical solution container 2. Further, it is easily guided to the bottom surface portion 40 while traveling along the surface of the peripheral wall portion 40 of the inner lid 4 on the chemical solution container 2 side. Therefore, it is possible to suppress the water that has entered the chemical liquid supply apparatus 1 from falling into the support 3 along the lower surface 27B of the chemical liquid container 2.

  Further, in the present embodiment, the peripheral wall portion 40 is inclined outward with an inclination angle larger than 90 ° with respect to the bottom surface portion 41 so that the lower end edge is located on the inner side than the upper end edge 42. Corresponding to the shape of the lower side surface 27B, the inclination angle gradually decreases from the front side to the back side in a side view. Further, the peripheral wall portion 40 is formed to have an angular polygonal shape corresponding to the shape of the lower side surface 27B of the chemical liquid container 2. As described above, the surface of the peripheral wall portion 40 of the inner lid 4 facing the lower side surface 27B has a shape corresponding to the shape of the lower side surface 27B of the chemical solution container 2, so that the water infiltrated into the chemical solution supply device 1 can be obtained. Is more likely to be guided to the bottom surface portion 40 not through the lower surface 27B of the chemical solution container 2 but through the surface of the peripheral wall portion 40 of the inner lid 4 on the chemical solution container 2 side. Therefore, it is possible to further effectively suppress the water that has entered the chemical solution supply apparatus 1 from dropping onto the support body 3 along the lower side surface 27B of the chemical solution container 2.

  Next, the bottom surface portion 41 is formed with a circular through hole 45 having a size in a plan view so as to be able to penetrate the mouth portion 21 of the chemical liquid container 2 at a substantially central position. In the present embodiment, the diameter of the through hole 45 coincides with the diameter of the lower step portion 60 a of the upper surface portion 60 of the cover member 6, and when the inner lid 4 is attached to the support body 3, the through hole 45 has the lower step portion 60 a. Located above the portion 60a. The chemical solution supply apparatus 1 is assembled by inserting the connection portion 64a of the discharge member 64 through the cap 23 into the discharge port 22 of the mouth portion 21 of the chemical solution container 2 through the through hole 45.

  In this embodiment, the through-hole 45 of the bottom surface portion 41 enters the chemical solution supply apparatus 1 from between the outer peripheral edge 24 of the chemical solution container 2 and the upper end edge 42 of the peripheral wall portion 40 and is guided downward by the peripheral wall portion 40. It also functions as a drainage hole for discharging the water transmitted to the bottom surface portion 41. A lower step portion 60a of the upper surface portion 60 of the cover member 6 is located below the through hole 45, and a portion outside the discharge member 64 in the lower step portion 60a is a hole communicating with the inside of the buffer chamber 7 such as the air hole 70. Therefore, even if the water that has entered the chemical solution supply device 1 falls into the support 3 from the through hole 45 (drainage hole), it can be prevented from entering the buffer chamber 7.

  In addition, the through-hole 45 does not necessarily need to correspond to the diameter of the lower stage part 60a of the upper surface part 60 of the cover member 6, and may be larger than the diameter of the lower stage part 60a. In this case, the water that has entered the chemical solution supply apparatus 1 falls from the through hole 45 (drainage hole) to the upper portion 60b of the upper surface portion 60 of the cover member 6, but in this embodiment, air also enters the upper portion 60b. Since holes such as the holes 70 that communicate with the buffer chamber 7 are not formed, it is possible to prevent water that has entered the chemical supply apparatus 1 from entering the buffer chamber 7.

  Further, as shown in FIG. 33, a drain hole 46 may be separately formed at a position outside the through hole 45 of the bottom surface portion 41. The drain holes 46 are preferably formed so as to surround the through holes 45, and in the illustrated example, a plurality of drain holes 46 are formed around the through holes 45 at intervals in the circumferential direction. In addition, the number and arrangement | positioning of the drain hole 46 are not necessarily limited to the thing of the example of illustration, It can be set as various numbers and arrangement | positioning. Even in this case, the water that has entered the chemical solution supply apparatus 1 falls from the drain hole 46 to the upper part 60b of the upper surface part 60 of the cover member 6, but in this embodiment, the buffer part such as the air hole 70 is provided in the upper part 60b. Since no hole communicating with the inside of the chemical liquid supply device 7 is formed, it is possible to prevent water that has entered the chemical solution supply apparatus 1 from entering the buffer chamber 7.

  However, when the air hole 70 is formed in the upper stage part 60b of the upper surface part 60 of the cover member 6, it is preferable to drop the water that has entered the chemical supply apparatus 1 to the lower stage part 60a.

  At least the surface of the peripheral wall portion 40 and the bottom surface portion 41 of the inner lid 4 on the side of the chemical liquid container 2 has a metallic luster. For example, by performing a plating process or applying a paint, it is possible to add a metallic glossy color such as gold, silver, or copper. When the peripheral wall portion 40 and the bottom surface portion 41 of the inner lid 4 are colored with a metallic luster on the surface on the side of the chemical liquid container 2, the metal of the inner lid 4 is used when the chemical liquid container 2 is transparent or translucent. Due to the gloss, the surface of the inner lid 4 is shining and visible through the outside of the chemical liquid container 2, so that the design (designability) of the chemical liquid supply apparatus 1 can be improved.

  Similarly to the peripheral wall portion 40, the bottom surface portion 41 is formed such that the surface on the chemical solution container 2 side (the surface on the side facing the lower end surface 26) forms an angular polygon. As described above, when the peripheral wall portion 40 and the bottom surface portion 41 of the inner lid 4 have a square shape on the side of the chemical liquid container 2, the metallic luster of the inner lid 4 appears to shine through the chemical liquid container 2. 1 designability (designability) can be improved more.

  The inner lid 4 may be provided with a color with metallic luster not only on the surface of the peripheral wall portion 40 and the bottom surface portion 41 on the side of the chemical solution container 2 but on the entire surface.

  When the chemical solution supply device 1 of the above-described embodiment is installed on the water supply tray of the flush toilet storage tank, the chemical solution in the chemical solution container 2 is discharged from the discharge member 64 to the guide member 5, and the guide member 5 The chemical solution on the surface is washed away by the water supplied to the water receiving tray at the time of flushing, and flows into the water storage tank from the drain outlet.

  At this time, the water that has fallen onto the chemical liquid container 2 from the water supply pipe on the water supply tray flows down along the surface of the chemical liquid container 2 and overlaps the outer peripheral edge 24 of the chemical liquid container 2 and the opening edge 32 of the support 3. However, since the inner lid 4 is interposed between the chemical liquid container 2 and the support 3, water is between the upper edge 42 of the peripheral wall portion 40 of the inner lid 4 and the outer peripheral edge 24 of the chemical liquid container 2. In some cases, the chemical solution supply apparatus 1 may enter through a gap inevitably generated. However, the water that has entered the chemical supply device 1 is guided downward by the peripheral wall portion 40 of the inner lid 4 and transmitted to the bottom surface portion 41, and then from the drainage hole (the through hole 45 in this embodiment) of the bottom surface portion 41. It falls into the support 3. Even if the water that has entered the chemical solution supply apparatus 1 is transmitted through the lower side surface 27B of the chemical solution container 2, the water after dropping on the inner lid 4 at a position other than the predetermined position is not 4 is guided downward by the peripheral wall portion 40 and falls into the support 3 from the drain hole of the bottom surface portion 41. And the lower step part 60a of the upper surface part 60 of the cover member 6 exists in the downward position of the through-hole 45 of the support body 3, The air hole 70 etc. exist in the part outside the discharge member 64 in the lower step part 60a. A hole communicating with the buffer chamber 7 is not formed. Therefore, even if the water that has entered the chemical solution supply device 1 falls into the support 3 from the through hole 45 (drainage hole), it can be prevented from entering the buffer chamber 7. Is prevented from being diluted. As a result, even if the chemical solution in the buffer chamber 7 is absorbed into the chemical solution container 2 due to a temperature change, the chemical solution in the chemical solution container 2 is prevented from being diluted, and the concentration of the chemical solution discharged from the chemical solution container 2 can be maintained appropriately. it can. Therefore, it is possible to supply a stable chemical solution.

  Thus, in the present invention, even when water enters the chemical solution supply apparatus 1, the infiltrated water can be dropped to a predetermined intended position in the support 3 by the inner lid 4, so that the support 3 so as not to form a hole communicating with the inside of the buffer chamber 7 such as the air hole 70 at a position where the water in the water 3 falls, so that the water that has entered the chemical supply apparatus 1 enters the buffer chamber 7. Can be prevented.

  Further, in the chemical liquid supply apparatus 1 of the present embodiment, the surface of the peripheral wall portion 40 of the inner lid 4 that faces the lower side surface 27B of the chemical liquid container 2 has a shape corresponding to the shape of the lower side surface 27B of the chemical liquid container 2. Therefore, the water that has entered the chemical solution supply apparatus 1 is guided to the bottom surface portion 41 through the surface of the peripheral wall portion 40 of the inner lid 4 rather than the lower side surface 27B of the chemical solution container 2. Therefore, the water that has entered the chemical solution supply apparatus 1 can be more effectively dropped by the inner lid 4 to a predetermined position in the support 3, and thus can be more suitably prevented from entering the buffer chamber 7. can do.

  Moreover, since the upper end edge 42 of the peripheral wall part 40 of the inner lid 4 protrudes outside the outer peripheral edge 24 of the chemical solution container 2 in the plan view, the chemical solution supply apparatus 1 of the present embodiment has a chemical solution from the surface of the chemical solution container 2. The water transmitted to the overlapping portion of the outer peripheral edge 24 of the container 2 and the opening edge 32 of the support 3 can be guided to the peripheral wall portion 40 of the inner lid 4 in an initiative. That is, it is possible to suppress water from being transmitted to the lower surface of the inner lid 4. As a result, the water that has entered the chemical solution supply apparatus 1 can be more effectively dropped by the inner lid 4 to a predetermined position in the support body 3, so that it is more preferable to enter the buffer chamber 7. Can be prevented.

  Moreover, since the upper end edge 42 of the peripheral wall part 40 of the inner lid 4 is inclined so that it may face diagonally upward toward the back side from the front side in the side view, the chemical solution supply apparatus 1 of this embodiment is the chemical solution container 2. The water transmitted from the surface of the outer peripheral edge 24 of the chemical liquid container 2 to the overlapping portion of the opening edge 32 of the support 3 is caused to flow down obliquely downward by the upper end edge 42 of the peripheral wall portion 40 of the inner lid 4. It can guide so that it may fall from the edge part of the front side in the side view of chemical | medical solution supply apparatus 1. FIG. Thereby, it can suppress that water permeates into the chemical solution supply apparatus 1.

  In addition, when the chemical solution supply device 1 is installed on the water supply tray with the front side shown in FIG. 2 facing forward and the back side shown in FIG. 3 facing back, the upper edge 42 of the peripheral wall portion 40 of the inner lid 4 is Since it faces diagonally upward toward the back side, the peripheral wall portion 40 of the inner lid 4 is easily visible from the outside through the chemical liquid container 2. The surface of the inner lid 4 is attached to the surface of the peripheral wall portion 40 and the bottom surface portion 41 of the inner lid 4 with a metallic luster so that the inner lid 4 can be moved from the outside of the chemical solution container 2 by the metallic luster of the inner lid 4. Can shine with sparkles. Therefore, the chemical solution supply apparatus 1 can be made more excellent in design. Furthermore, since the metallic luster of the inner lid 4 appears to be more brilliant by forming the surfaces of the peripheral wall portion 40 and the bottom surface portion 41 of the inner lid 4 to be square, the chemical solution supply device 1 can be more effectively improved in design. Can be.
