In the chemical liquid supply device having the above-described configuration, if a large amount of running water supplied from the water discharge tap to the hand washing part hits the guide member vigorously, the running water may bounce off the guide member and be scattered from the hand washing part.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a chemical liquid supply device in which running water supplied to a hand-washing section is less likely to scatter.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical liquid supply device that is installed in a hand washing part above a water storage tank of a flush toilet and supplies chemical liquid to running water for hand washing that flows intermittently. The chemical liquid supply device of the present invention includes a chemical liquid container for containing a chemical liquid, a support placed on a hand washing part to support the chemical liquid container from below, and at least a part of the drain port of the hand washing part is inserted. At least a part is inserted into the drainage port of the hand-washing section together with a guide member that protrudes downward from the bottom of the support body and guides the chemical liquid onto the drainage port, outside the drainage port of the hand-washing section or the guide member of the support body. A water blocking wall that is located outside the long leg and that blocks a part of the flowing water flowing between the support and the hand washing part on the support side, and is arranged at least at a part of the periphery of the guide member. And an impermeable wall.

In the chemical liquid supply device of the present invention, it is preferable that the impermeable wall is arranged over the entire circumference of the guide member.

Further, in the chemical liquid supply device of the present invention, it is preferable that the water blocking wall is arranged outside a shielding member that surrounds the guide member.

Further, in the chemical liquid supply device of the present invention, water supplied to the hand-washing section is guided to the drain port, which is arranged on the outer side of the impermeable wall and inwardly inclines as the outer surface goes downward. It is preferable to further include a guiding member for controlling.

Further, it is preferable that the chemical liquid supply device of the present invention further includes a cover which covers the chemical liquid container and covers the support.

According to the present invention, after the chemical solution supply device is installed in the hand washing part provided in the upper part of the water storage tank of the flush toilet, when the running water from the tap is dropped onto the chemical solution supply device, the running water travels on the surface of the chemical solution supply device. It falls on the hand washing part. Then, the running water that has flowed down onto the hand washing section flows toward the drain port between the support of the chemical liquid supply device and the hand washing section, and by exposing the chemical solution on the guide member at least a part of which is inserted into the drain port. , The chemical liquid is supplied to the running water, and flows into the water storage tank from the drain port together with the running water. At this time, the running water flowing between the support and the hand washing part flows so as to hit the guide member of the chemical liquid feeder on the lower side (hand washing part side), but on the upper side (support side) of the impermeable wall. When it hits, the flow toward the guide member is blocked, and it flows toward the running water on the lower side (hand washing section side) or in the opposite direction to the flowing water on the lower side (hand washing section side). As a result, the flow of water on the lower side (hand washing part side) flowing over the hand washing part toward the guide member is weakened by the effect of running water on the upper side (support side), so that the guide member is vigorously hit. It can be prevented. Therefore, even if a large amount of running water is supplied from the water discharge tap to the hand washing part, it is possible to prevent the running water from splashing back from the hand washing part by the guide member.

The concave portion 32 constitutes a part of the bottom portion of the support body 7, and the concave portion 32 is provided with a plurality of (for example, four) short legs 34 protruding downward. As shown in FIG. 13, each short leg 34 causes the support 7 to be placed substantially horizontally on the hand washing part 10 when the support 7 is placed on the hand washing part 10.

In addition, as shown in FIGS. 2 and 4 to 7, an opening 35 having a rectangular shape in plan view is formed in the recess 32 at the center position. The bottom member 5 is fitted into the recess 32, and at this time, the guide member 50 and the long leg 56 of the bottom member 5 can project below the recess 32 through the opening 35. Engaging claws 36 are provided outside the recesses 32 in the lateral direction of the lower container 3 via arms 39 extending upward. When the bottom member 5 is fitted into the concave portion 32 of the lower container 3, the pair of engaging claws 36 engages with the pair of engaging projections 43 of the lid member 4 covered by the bottom member 5 in a one-to-one relationship. The lid member 4 and the bottom member 5 are fixed to the lower container 3.

The annular protrusion 31 is fitted into the side surface portion 81 of the cover 8 to be described later when the cover 8 is placed on the support 7 (lower container 3). This facilitates the positioning of the cover 8 that covers the support 7 (lower container 3). Further, the width of the peripheral edge portion 33 is almost the same as the thickness of the side surface portion 81 of the cover 8, and the side surface portion 81 abuts the peripheral edge portion 33 when the cover 8 is covered on the support 7 (lower container 3). As a result, the cover 8 is stably placed on the support 7 (lower container 3).

When the support 7 is placed on the hand washing part, the lower container 3 is located outside the drain of the hand washing part and flows between the support 7 and the hand washing part toward the guide member 50. A water blocking wall 37 that blocks a part of the support 7 side is provided. In the present embodiment, the water shield wall 37 is arranged outside the long leg 56 of the bottom member 5 and also outside the shield member 59 surrounding the guide member 50 described later. The water blocking wall 37 may be arranged at least at a part of the periphery of the guide member 50, but is preferably arranged over the entire circumference of the guide member 50 as in the present embodiment.

The impermeable wall 37 has a wall surface extending in the up-down direction in parallel with the peripheral surface of the guide member 50, and a part of the running water flowing between the support body 7 and the hand washing part hits the wall surface, A part of the running water is blocked from flowing toward the guide member 50. The wall surface may be formed to incline outward as it goes downward. In the present embodiment, the impermeable wall 37 is arranged over the entire circumference of the guide member 50 on the outer side of the recess 32, but a part of the impermeable wall 37 extends downward from the lower surface of the bottom surface portion 30 of the lower container 3. While being formed, the rest is composed of other members. Specifically, in the lateral direction of the lower container 3, each arm 39 of the pair of engaging claws 36 located outside the recess 32 also constitutes the water blocking wall 37. Further, in the longitudinal direction of the lower container 3, the recess 32 located inside and below the water shield wall 37 also constitutes the water shield wall 37, and the water shield wall 37 has a step.

When the support body 7 is installed in the hand washing part, running water from the water discharge tap (not shown) flows down onto the hand washing part and flows between the hand washing part and the support body 7 toward the drain port. Here, if the lower container 3 is not provided with the impermeable wall 37, as shown in FIG. 13(A), running water flowing between the hand washing part 10 and the support 7 vigorously hits the guide member 50. If a large amount of running water is supplied from the water discharge tap to the hand washing section 10, the running water may bounce off the guide member 50 and be scattered from the hand washing section 10.

On the other hand, when the lower container 3 is provided with the impermeable wall 37, as shown in FIG. 13B, among the running water flowing between the hand washing part 10 and the support 7, the lower side (hand washing).

It may flow toward the running water on the (hand washing part 10 side) or may flow in the opposite direction to the flowing water on the lower side (hand washing part 10 side). As a result, the flow of the running water on the lower side (hand washing part 10 side) flowing on the hand washing part 10 toward the guide member 50 is weakened by the effect of running water on the upper side (support body 7 side), so that the running water flows to the guiding member 50. Can be prevented from hitting vigorously. Even if the amount of running water supplied from the water discharge tap to the hand washing unit 10 is large, it is possible to prevent the running water from splashing back from the hand washing unit 10 by the guide member 50.

The lower container 3 is provided with a guide member 38 arranged outside the water shield wall 37. The guide member 38 is arranged outside the guide member 50 on the opposite side to correspond to each of the plurality of short legs 34. Each guiding member 38 is formed shorter than each short leg 34, and as shown in FIG. 14, when the support body 7 is placed on the hand washing part 10, it floats without hitting the hand washing part 10. ..

The outer surface of each guide member 38 is inclined inward (toward the guide member 50) as the outer surface faces downward, and as shown in FIG. 14, the water supplied to the hand washing part 10 is directed toward the drain port 11. Play a guiding role. As a result, the water supplied to the hand washing unit 10 flows smoothly into the drain port 11.

Next, as shown in FIGS. 4, 9 and 10, the bottom member 5 includes a bottom wall 54 having a substantially rectangular shape in plan view, and a peripheral wall 55 having a substantially rectangular frame shape protruding upward from a peripheral edge of the bottom wall 54. And a plate-shaped guide member 50. The bottom wall 54 constitutes a part of the bottom portion of the support 7, and the bottom wall 54 is provided with a plurality of (two in the illustrated example) long legs 56 protruding downward. Further, a through hole 57 is formed in the bottom wall 54 at a central position.

Each long leg 56 has a length that protrudes downward longer than the surrounding short legs 34 when the bottom member 5 is fixed to the lower container 3, and as shown in FIG. When it is placed on the hand washing part 10, it is inserted into the drain port 11 of the hand washing part 10.

Returning to FIG. 4, FIG. 9, and FIG. 10, the inner wall 41 of the lid member 4, which will be described later, is fitted inside the peripheral wall 55. A notch 58 is formed in the upper end of the peripheral wall 55 by notching in a concave shape at a position facing each other.

The guide member 50 projects downward from the bottom wall 54 so as to cross the through hole 57. The guide member 50 guides the chemical liquid discharged from the chemical liquid container 2 to the bottom member 5 via the connection member 44 and the discharge member 45 of the lid member 4 described later to a position where the chemical liquid flows under the bottom member 5 and comes into contact therewith. It is for. The upper end of the guide member 50 is provided with a fitting protrusion 51 that protrudes above the bottom wall 54 through the through hole 57. The fitting protrusion 51 can be fitted into the discharge member 45 of the lid member 4 described later. A vertical groove 52 extending from the upper end to the lower end is formed on the outer peripheral surface of the fitting protrusion 51, and the vertical groove 52 guides the drug solution passing through the discharge member 45 to the guide member 50 by a capillary action.

A large number of narrow grooves 53 extending in the vertical direction are formed on the front surface and the back surface of the guide member 50. The guide member 50 is located between the two long legs 56, and is inserted into the drain port 11 of the hand washing part 10 together with the long legs 56, as shown in FIG. 13. The guide member 50 is formed to be slightly shorter than each long leg 56, and only the lower end portion thereof is inserted into the drainage port 11. When the running water supplied to the hand washing unit 10 comes into contact with the guide member 50, the chemicals on the front and back surfaces of the guiding member 50 are exposed to the running water and flow into the water storage tank from the drain port 11 together with the running water.

Returning to FIG. 4, FIG. 9 and FIG. 10, a shielding member 59 having a substantially rectangular frame shape is provided between the guide member 50 and each long leg 56. The shield member 59 is formed to be shorter than the guide member 50, and restricts the flowing water supplied to the hand washing section from flowing backward from the guide member 50 into the bottom member 5.

Next, as shown in FIG. 2, FIG. 4, FIG. 8 and FIG. 10, the lid member 4 includes an upper surface portion 40 having a substantially rectangular shape in plan view, and an inner wall 41 having a substantially rectangular frame shape and hanging from the upper surface portion 40. , And an outer side wall 42 that is located outside the inner side wall 41 and hangs down from the peripheral edge of the upper surface portion 40. By fitting the inner side wall 41 inside the peripheral wall 55 of the bottom member 5, the lid member 4 is attached to the bottom member 5, and the buffer chamber 6 is formed between the lid member 4 and the bottom member 5. The buffer chamber 6 is a space capable of storing a chemical solution.

The outer side wall 42 is separated from the outer peripheral surface of the peripheral wall 55 of the bottom member 5 when the lid member 4 is attached to the bottom member 5. A pair of engaging protrusions 43 protruding outward are provided at the lower end of the outer wall 42, and the pair of engaging protrusions 43 can engage with the pair of engaging claws 36 of the lower container 3 in a one-to-one manner. ..

The inner wall 41 is formed with a pair of notches 47 extending vertically from the upper end to the lower end. The pair of notches 47 are arranged so as to correspond to the pair of notches 58 of the peripheral wall 55 of the bottom member 5 in a one-to-one correspondence. When the lid member 4 is attached to the bottom member 5, the notch 47 and the notch 58 are aligned with each other, so that an air circulation hole for circulating air is formed in the buffer chamber 6.

The upper surface portion 40 is composed of a lower step portion 40a having a circular shape in plan view at the center thereof and an upper step portion 40b around the lower step portion 40a located at a position higher than the lower step portion 40a. A cylindrical connecting member 44 to be inserted into the mouth portion 21 of the drug solution container 2 is provided at a central position of the lower step portion 40a.

The connecting member 44 is provided on the lower step portion 40a of the upper surface portion 40 so as to protrude above the upper step portion 40b. The upper end of the connecting member 44 is obliquely cut off and sharpened so that the thin portion of the cap 22 can be easily pierced when the connecting member 44 is inserted into the mouth portion 21 of the liquid medicine container 2.

A discharge member 45 protruding downward is provided on the lower step portion 40a of the upper surface portion 40. The discharge member 45 has a cylindrical shape with a diameter smaller than that of the connection member 44, and is arranged concentrically with the connection member 44. The connection member 44 and the discharge member 45 are in communication with each other, and the insides of the connection member 44 and the discharge member 45 form a chemical liquid passage for passing the chemical liquid from the chemical liquid container 2 to a guide member 50 described later. The inside of the discharge member 45 is partitioned from the buffer chamber 6, and the discharge member 45 can be fitted into the through hole 57 of the bottom member 5.

A plurality of small-diameter liquid passage holes 46 (three in the illustrated example) are formed inside the connection member 44 of the lower step portion 40a and outside the discharge member 45. The liquid passage hole 46 introduces a part of the chemical liquid discharged from the chemical liquid container 2 via the connection member 44 into the buffer chamber 6.

The buffer chamber 6 adjusts the amount of the drug solution discharged from the drug solution container 2 even when the pressure changes in the drug solution container 2 due to the temperature change. The buffer chamber 6 acts as follows with respect to the temperature change of the chemical liquid container 2.

For example, when the temperature rises and the drug solution container 2 is warmed, the air in the drug solution container 2 expands and the pressure inside the drug solution container 2 becomes positive. In this case, the chemical liquid in the chemical liquid container 2 is pushed out and discharged from the mouth portion 21, but the discharged chemical liquid flows from the connection member 44 and the discharge member 45 to the guide member 50, and also through the liquid passage hole 46. It also flows into the buffer chamber 6. Therefore, the chemical liquid is prevented from excessively flowing out to the guide member 50.

On the other hand, when the temperature of the drug solution container 2 is lowered by being cooled by running water, the air in the drug solution container 2 contracts and the drug solution container 2 has a negative pressure. In this case, the chemical liquid in the buffer chamber 6 which is at atmospheric pressure or room pressure due to the action of the air circulation holes (notch 47 and notch 58) is sucked into the chemical liquid container 2 through the liquid passage hole 46. Be done. Therefore, the water on the guide member 5 or the diluted chemical liquid is suppressed from returning to the chemical liquid container 2 side through the discharge member 45 and the connection member 44. Further, it is possible to prevent the negative pressure in the liquid medicine container 2 from limiting the discharge of the liquid medicine.

Next, as shown in FIG. 1, FIG. 2 and FIG. 11, the cover 8 has a first direction (left and right direction in FIG. 11A) in a plan view, like the chemical liquid container 2 and the lower container 3. It has a laterally elongated outer shape whose length is longer than the length in the second direction (vertical direction in FIG. 11A) orthogonal to this, and in the present embodiment, it is formed in a substantially elliptical shape in plan view. There is. The cover 8 can be formed of, for example, synthetic resin, earthenware, glass, or the like.

The cover 8 includes a top surface portion 80, a cylindrical side surface portion 81 having an opening at a lower portion, and an inclined surface portion 82 connecting the top surface portion 80 and the side surface portion 81 in at least a portion in the circumferential direction. The top surface portion 80 has a substantially elliptical shape in a plan view, and the upper surface thereof has a convex curved surface shape that gently bulges from the peripheral edge toward the center.

The side surface portion 81 has a substantially elliptical shape in plan view like the top surface portion 80. The side surface portion 81 is formed so as to extend straight downward, but may be formed so as to be inclined outward as it goes downward, or may be formed so as to be inclined inward as it goes downward. It may have been done.

The inclined surface portion 82 is bent downward at the connection position with the top surface portion 80. That is, the inclined surface portion 82 is not connected to the top surface portion 80 by a round and smooth curve, but the inclined surface portion 82 and the top surface portion 80 are connected so as to form a V-shape protruding outward in a sectional view, 8 has an angular shape at the connection position between the inclined surface portion 82 and the top surface portion 80. The corners at the connection position between the inclined surface portion 82 and the top surface portion 80 may be chamfered. It is sufficient for the inclined surface portion 82 to connect the top surface portion 80 and the side surface portion 81 in at least a part in the circumferential direction, but the top surface portion 80 and the side surface portion 81 are connected over the entire circumference in the circumferential direction as in the present embodiment. Preferably.

Further, the inclined surface portion 82 is obliquely inclined between the top surface portion 80 and the side surface portion 81, but may have a linear shape in a sectional view, or may have a concave curved shape that is recessed inward in a sectional view. It may be formed, but as in the present embodiment, it is preferably formed in a concave curved shape in a sectional view.

Since the cover 8 is located on the outermost side among those supported from below by the support body 7, when the support body 7 is installed in the hand washing part, the cover 8 is placed directly above the water discharge tap ( It will be flooded with running water (not shown). The running water from the water discharge tap falls on the top surface portion 80 of the cover 8, and then flows from the top surface portion 80, the inclined surface portion 82, the side surface portion 81, and the hand washing portion.

Here, when the inclined surface portion 82 is connected to the top surface portion 80 by a round and smooth convex curve, it is vigorously dropped from the water discharge tap onto the cover 8 as shown in FIG. 12(B). When the running water flows down from the top surface portion 80 along the surface, a part of the running water jumps out in the lateral direction as it is at the time of the falling force and scatters from the hand washing part.

On the other hand, if the inclined surface portion 82 is bent downward at the connection position with the top surface portion 80, as shown in FIG. 12(A), the inclined surface portion 82 may jump out in the lateral direction of the running water flowing from the top surface portion 80. And the momentum to be weakened. Therefore, even if the running water vigorously drops from the water discharge tap onto the cover 8, the running water that has dropped onto the cover 8 has a gentle flow at the inclined surface portion 82 when flowing down along the surface, It is possible to suppress jumping out in the direction, and to prevent scattering from the hand washing section.

Further, when the inclined surface portion 82 has a linear shape in a sectional view, and preferably has a concave curved shape shown in FIG. 12A, the flow of water when the flowing water flows down the inclined surface portion 82 can be made more gradual. it can. Therefore, when the running water that has dropped onto the cover 8 flows down along the surface, it can be more effectively suppressed from jumping out in the lateral direction, and can be prevented from splashing from the hand washing section.

Although the inclination angle of the inclined surface portion 82 with respect to the top surface portion 80 is not particularly limited, in order to achieve the effect of gradually reducing the flow of water flowing down the surface of the cover 8 described above by the inclined surface portion 82, It is more preferably 20° or more and 70° or less, and preferably 30° or more and 60° or less. In addition, when the inclined surface portion 82 is formed in a concave curved shape in a cross-sectional view, the angle formed by the tangent line at the connection position of the inclined surface portion 82 with the top surface portion 80 and the top surface portion 80 in the cross sectional view is the inclination angle. Can be

Further, when the inclined surface portion 82 is formed in a concave curved shape in a sectional view, the radius of curvature of the inclined surface portion 82 is not particularly limited, but the flow of water flowing down the surface of the cover 8 described above is inclined. In order to satisfactorily achieve the effect of loosening the surface portion 82, it is preferably 5 mm or more and 15 mm or less, and more preferably 8 mm or more and 10 mm or less.

Further, at least a part of the surface of the cover 8 exposed to the outside is hydrophilic. Here, the “externally exposed surface” of the cover 8 means a surface that can be seen from the outside of the cover 8 in a state where the cover 8 is covered on the support 7, and an invisible surface inside the cover 8 or , A surface excluding a surface hidden by another member (such as the support 7) such as the lower end surface of the side surface portion 81.

Further, “hydrophilic” has a high affinity with water, and in the present invention, it means that the contact angle of the surface of the cover 8 with water is less than 90°. Since the cover 8 has a high affinity with water, the surface thereof is easily adapted to water, and the water dropped from the water discharge tap spreads in a thin film shape so that the surface of the cover 8 sticks to the surface of the cover 8. The area where water contacts the surface becomes large. As a result, the running water that has dropped from the water discharge onto the cover 8 flows down along the surface of the cover 8 while sticking to the surface of the cover 8 rather than being repelled by the surface of the cover 8. Therefore, it is possible to prevent water from splashing on the surface of the cover 8 and splashing from the hand washing section.

The contact angle of the surface of the cover 8 with water is not particularly limited as long as it is less than 90°, but the above-described effect that the water flows so that it sticks to the surface of the cover 8 thinly is improved. In order to achieve it, it is preferably 80° or less, and more preferably 70° or less. The lower limit of the contact angle is not particularly limited, but is preferably 5° or more, more preferably 10° or more.

For the contact angle, after removing dirt on the surface of the hydrophilic member such as the cover 8, a droplet of water of about 6 μL is deposited on the surface of the member using a micropipette, for example, and 1000 ms later. The contact angle of a droplet can be measured by a contact angle meter (Kyowa Interface Science Co., Ltd.: DropMaster500, measurement analysis integration software: FAMAS).

In order to impart hydrophilicity to a member having hydrophilicity such as the cover 8, for example, when the member is made of synthetic resin, a hydrophilic treatment agent is applied to the surface, or when the member is made of glass or earthenware. Examples thereof include coating a hydrophilic inorganic coating such as glaze on the surface thereof, or molding the member with a synthetic resin material containing a hydrophilic treatment agent.

The hydrophilic treatment agent may include, for example, a nonionic surfactant. Specific examples thereof include polyoxyalkylene hydrogenated castor oil such as polyoxyethylene hydrogenated castor oil; polyoxyalkylene hydrogenated castor oil ether such as polyoxyethylene hydrogenated castor oil ether; polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, Polyoxyalkylene glyceryl ether such as polyoxyethylene decyl ether and polyoxyalkylene decyl ether; Polyoxyalkylene fatty acid ester such as polyoxyethylene fatty acid ester; Polyoxyalkylene glycerin fatty acid ester such as polyoxyethylene glycerin fatty acid ester; Alkyl alkanolamide Alkyl polyglucoside; polyglycerin fatty acid ester; sorbitan fatty acid ester; glycerin fatty acid ester; polyoxyethylene sorbitan fatty acid ester; polyoxyethylene polyoxypropylene glycol and the like. Preferred are glycerin fatty acid ester, polyglycerin fatty acid ester, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, and polyoxyethylene glycerin fatty acid ester.

In the present embodiment, the cover 8 is not formed with an opening so that running water does not enter therein, but the cover 8 may be formed with one or a plurality of openings.

According to the chemical liquid supply device 1 of the present embodiment described above, as shown in FIG. 13(B), after being installed in the hand washing part 10 provided in the upper part of the water storage tank of the flush toilet, the running water from the tap is discharged. When it falls onto the supply device 1, the running water flows along the surface of the cover 8 to the hand washing unit 10 and then flows between the support 7 and the hand washing unit 10 toward the drain port 11. Of the running water flowing between the hand-washing section 10 and the support 7, the lower side (hand-washing section 10 side) flows so as to hit the guide member 50 on the drain 11, but the upper side (support 7 side). With respect to, the flow toward the guide member 50 is blocked by hitting the impermeable wall 37, and flows toward the running water on the lower side (hand washing section 10 side), or reverse to the flowing water on the lower side (hand washing section 10 side). It flows in the direction. As a result, the flow of the running water on the lower side (hand washing part 10 side) flowing on the hand washing part 10 toward the guide member 50 is weakened by the effect of running water on the upper side (support body 7 side), so that the running water flows to the guiding member 50. Can be prevented from hitting vigorously. Even if the amount of running water supplied from the water discharge tap to the hand washing unit 10 is large, it is possible to prevent the running water from splashing back from the hand washing unit 10 by the guide member 50.

Further, since the outer surface of each guide member 38 is inclined inward (toward the guide member 50) as the outer surface thereof faces downward, as shown in FIG. 14, the water supplied to the hand washing part 10 is drained. Guide towards. Therefore, the water supplied to the hand washing part 10 can be smoothly flowed toward the drain port 11.
