Description

[Technical Field]

[0001] The present invention relates to a chemical liquid supplying device that is attached to a water storage tank of a toilet, which has a tank body with an opening at the top and a lid body that closes the opening of the tank body. [Background technology]

[0002] Conventionally, there has been known a chemical liquid supply device that is installed in a hand-washing water supply tray above a toilet water tank and supplies chemical liquid for cleaning, deodorizing, and fragrance to the flush water in the water tank (see, for example, Patent Document 1). Also known is a discharge tool that discharges a gel-like chemical onto the inner surface of a toilet bowl, adhering it like a stamp (see, for example, Patent Documents 2 and 3). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-79496 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-124596 [Patent Document 3] Japanese Patent Application Publication No. 2017-218234 Summary of the Invention [Problem to be solved by the invention]

[0004] A medicinal liquid dispenser such as that described in Patent Document 1 cannot be installed if there is no water supply tray for hand washing. Even if there is a water supply tray, the medicinal liquid dispenser cannot be installed if, for example, decorative items are placed in the water supply tray. On the other hand, when a discharge device such as those described in Patent Documents 2 and 3 is used, the amount of medicinal liquid that can be adhered to the inner surface of the toilet bowl with one stamp is limited, and there is also a risk that the medicinal liquid on the inner surface of the toilet bowl will peel off during flushing, making it impossible to stably dispense the medicinal liquid.

[0005] An object of the present invention is to provide a chemical liquid supplying device that can easily secure an installation location and can stably supply a chemical liquid. [Means for solving the problem]

[0006] The drug supply device of the present invention is a drug supply device that is attached to a water tank of a toilet having a tank body with an opening at the top and a lid body that covers the opening of the tank body, and comprises a drug container that stores the drug, a flexible tube that supplies the drug from the drug container to the water tank, and a mounting member that supports the tube and is configured to be attached to the edge of the top opening of the tank body, the mounting member comprising an abutment portion that can abut against the outer surface of the tank body, and a fixing portion that, in an initial state, extends downward from the abutment portion across the edge of the tank body and along the inner surface of the tank body, the fixing portion being formed of a flexible material and, in an initial state, being formed so as to be convex upward so as to climb over the edge of the tank body, and the tube being arranged to follow the fixing portion.

[0007] In the medicine supply device, the portion of the fixing part that forms the convex portion can be curved.

[0008] In the medicine supply device, an upper portion of the contact portion may have a mounting surface on which an edge extending downward from an outer peripheral edge of the lid body can be mounted.

[0009] In the above-mentioned drug supply device, the mounting member can be provided with a receiving portion that is positioned above the abutment portion and has a recess formed therein to receive the drug solution discharged from the drug solution container, and the receiving portion, the abutment portion, and the fixing portion are integrally formed from a flexible material, and the tube can be connected to the recess.

[0010] In the medicine supply device, the tube may be arranged along the fixing portion. [Effects of the Invention]

[0011] According to the present invention, the chemical supply device can be attached to a water storage tank that does not have a water supply tray because it has an attachment member that can be attached to the edge of the opening of the tank body. Furthermore, the attachment member supports a flexible tube that guides the chemical solution from the chemical solution container to the water storage tank, so the chemical solution from the chemical solution container can be stably supplied to the water storage tank by this tube.

[0013] A chemical liquid supplying device according to one embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a perspective view of the chemical liquid supplying device according to this embodiment, Fig. 2 is an exploded side view of the chemical liquid supplying device of Fig. 1, and Fig. 3 is a cross-sectional view of a water storage tank.

[0014] As shown in Figures 1 and 2, this chemical liquid supply device is a device that supplies chemical liquid to a toilet water tank 1, and is equipped with a chemical liquid container 2 that stores the chemical liquid, a chemical liquid guide member 3 for discharging the chemical liquid from the chemical liquid container 2, a support body 4 that supports the chemical liquid container 2 and receives the chemical liquid, and an attachment member 5 for attaching the support body 4 to the toilet water tank 1.

[0015] As shown in FIG. 3, the target water storage tank 1 includes a tank body 11 that stores flushing water and a lid 12 that closes the top opening of the tank body 11. The tank body 11 has a first edge 121 extending downward on the outer periphery of the lid 12, and a second edge 122 that is spaced apart inside the first edge 121. The edge 111 of the top opening of the tank body 11 fits between the first edge 121 and the second edge 122 of the lid 12. Therefore, the lid 12 is installed so that it protrudes slightly outward from the outer periphery of the tank body 11. The above-mentioned mounting member 5 is attached so as to be sandwiched between the tank body 11 and the lid 12. Each component of the chemical solution supply device will be described in detail below.

[0016] <1. Chemical container> Fig. 4 is a perspective view of a liquid medicine container. As shown in Fig. 4, liquid medicine container 2 has container body 21 formed in a transparent dome shape with a flat bottom surface, and liquid medicine is stored in container body 21. Discharge outlet 211 is formed in the bottom surface of container body 21, and cap 22 is attached to discharge outlet 211 before use. Cap 22 is composed of an annular main body portion 221 and a thin film portion 222 that closes the central hole, and when used, thin film portion 222 is broken to discharge the liquid medicine.

[0017] The chemical solution contains one or more elements selected from the group including a cleaning agent, a disinfectant, a deodorizer, and an air freshener, and may also contain a coloring agent. The chemical solution is mixed with flush water stored in a water storage tank, and the effects of the ingredients contained in the chemical solution are provided in the toilet bowl or the toilet room. For example, if the chemical solution contains a cleaning agent and a disinfectant, it can clean and disinfect the toilet bowl, and if it contains a deodorizer and an air freshener, it can eliminate unpleasant odors and fill the toilet room with a pleasant fragrance.

[0018] <2. Chemical solution guide member> FIG. 5 is a perspective view of the liquid medicine guide member. The liquid medicine guide member 3 guides the liquid medicine discharged from the liquid medicine container 2 to the support 4. As shown in FIG. 5, the liquid medicine guide member 3 has a rectangular upper surface 31 and side surfaces 32 extending downward from the periphery thereof. An annular recess 311 is formed in the center of the upper surface 31, and the main body 221 of the cap 22 of the liquid medicine container 2 fits into this recess 311. A cylindrical communicating tube 33 with a sharp, obliquely notched tip is provided inside the recess 311. The communicating tube 33 is designed to pierce the thin film portion 222 of the cap 22 of the liquid medicine container 2. This allows the liquid medicine in the liquid medicine container 2 to flow through the communicating tube 33 to the receiving portion 42 of the support 4, which will be described next. A protrusion 34 is formed at an opposing position on the side surface 32.

[0019] <3.Support> Next, the support body 4 will be described. Fig. 6 is a perspective view of the support body seen from above, and Fig. 7 is a perspective view of the support body seen from below. As shown in Figs. 6 and 7, the support body 4 has a housing 41 that is elliptical in plan view. The internal space surrounded by the housing 41 is provided with a receiving portion 42 to which the drug solution guide member 3 is attached, a pair of support plates 43 that are arranged below the receiving portion 42 and support the receiving portion 42, and a fixing plate 44 for fixing the mounting member 5.

[0020] Housing 41 has a pair of long wall portions 411 extending in the longitudinal direction and a pair of curved short wall portions 412 extending in the lateral direction, and is configured to support drug solution container 2 at the upper ends thereof. Housing 41 also has a plurality of openings 413 formed therein, and the internal space of housing 41 communicates with the outside via these openings 413. Note that openings 413 may be omitted in some of the drawings.

[0021] The pair of support plates 43 are arranged at a predetermined interval in the internal space of the housing 41 and extend in the short direction. Both ends of each support plate 43 are connected to the inner wall surface of the housing 41. A receiving portion 51 of the mounting member 5, which will be described later, is arranged between these support plates 43.

[0022] Both sides of the fixed plate 44 are connected to the support plates 43, and the fixed plate 44 extends longitudinally between these support plates 43. The fixed plate 44 is disposed closer to one of the long wall portions (hereinafter referred to as the first long wall portion 411a, and the other long wall portion as the second long wall portion 411b) than the center of the internal space in the short-side direction. A receiving portion 51 of the mounting member 5, which will be described later, is fitted between the second long wall portion 411b and the fixed plate 44. More specifically, the distance between the second long wall portion 411b and the fixed plate 44 is slightly shorter than the length of the receiving portion 51 in the short-side direction. Therefore, the flexible receiving portion 51 is press-fitted between the second long wall portion 411b and the fixed plate 44.

[0023] An engagement portion 45 is provided at the upper end of each support plate 43 to elastically deform and engage with the protrusions 34 on both sides of the chemical solution guide member 3, and a receiving portion 42 for receiving the chemical solution is disposed between these engagement portions 45. The receiving portion 42 is formed in a rectangular cup shape in a plan view, and a through-hole 421 is formed in the center of the bottom surface. The outer edge of the receiving portion 42 is adapted to fit inside the side surface portion 32 of the chemical solution guide member 3. A guide plate 46 is formed extending downward from the bottom surface of the receiving portion 42, and the chemical solution that passes through the through-hole 421 flows downward along the guide plate 46. The guide plate 46 is disposed near the center of the lateral direction of the housing 41 and faces the second long wall portion 411b.

[0024] <4. Mounting parts> Fig. 8 is a side view of the mounting member, Fig. 9 is a perspective view of the mounting member seen from above, and Fig. 10 is a perspective view of the mounting member seen from behind. As shown in Figs. 8 to 10, mounting member 5 comprises a receiving portion 51 attached to support body 4, a contact portion 52 connected to the lower end surface of receiving portion 51, a fixing portion 53 extending from contact portion 52 so as to climb over edge 111 of tank body 11, and a folded portion 54 extending from the end of fixing portion 53 toward contact portion 52, all of which are integrally formed from a flexible material. In addition, a known flexible tube 6 is attached to mounting member 5.

[0025] Receiving portion 51 is formed in the shape of an octagonal block in a plan view, with rectangular recess 511 formed in the center of the top surface. The bottom surface of recess 511 is formed in a cone shape, with discharge hole 512 formed at the bottom. A rod-shaped member 513 having a through-hole communicating with discharge hole 512 is attached to the part of the underside of receiving portion 51 where recess 511 is formed. Rod-shaped member 513 is inserted into the upper end of tube 6, and the medicinal solution that accumulates in recess 511 flows into tube 6 via discharge hole 512 and the through-hole.

[0026] The abutting portion 52 has a front plate 55 extending downward from the receiving portion 51 and a pair of side plates 56 connected to both sides of the front plate 55, and the front plate 55 is supported by the pair of side plates 56. The front plate 55 has a first extending surface 551 extending downward from the outer circumferential surface of the receiving portion 51 facing the water tank 1, a curved surface 552 curving downwardly from the lower end of the first extending surface 551, a second extending surface 553 extending obliquely upward from the curved surface 552, and an abutting surface 554 extending downward from the end of the second extending surface 553. Furthermore, the edge of each side plate 56 facing the water tank 1 is formed to fit along the first extending surface 551, the curved surface 552, the second extending surface 553, and the abutting surface 554. On the other hand, the edge of each side panel 56 opposite to the water tank 1 extends obliquely in a straight line from the lower end of the receiving portion 51 to the lower end of the abutting surface 554 .

[0027] In the front panel 55, a through hole 555 is formed in the curved surface 552, and a first groove 556 is formed in the second extending surface 553, extending toward the water tank 1 side so as to be continuous with the through hole 555. As described above, the tube 6 inserted into the rod-shaped member 513 is pulled out toward the water tank 1 side through the through hole 555 and is arranged so as to follow the first groove 556 in the second extending surface 553. The first groove 556 is formed in an arc-shaped cross section, and is formed so as to fill 30% or more, preferably 50% or more, of the cross-sectional area of ​​the tube 6.

[0028] Furthermore, a plate-shaped guide member 557 is disposed on the back surface of the first extending surface 551 of the front panel 55. This guide member 557 extends upward from the upper edge of the through-hole 555 and is disposed with a gap between it and the rod-shaped member 513. Furthermore, the edge of the guide member 557 that extends from the rod-shaped member 513 to the through-hole 555 is formed in an arc shape. Therefore, the tube 6 inserted into the rod-shaped member 513 is disposed so as to follow the edge of the guide member 557 and is guided toward the through-hole 555.

[0029] Next, the fixing portion 53 will be described. In its initial state, the fixing portion 53 is formed in a strip shape having a curved portion 531 extending convexly upward from the upper end of the second extending surface 553 described above, and an extending portion 532 extending downward from the tip of the curved portion 531. The fixing portion 53 is formed with a second groove 533 that is continuous with the first groove 556 formed in the second extending surface 553. The second groove 533 has a cross-sectional shape similar to that of the first groove 556 and extends across the curved portion 531 and the extending portion 532. In addition, the extending portion 532 is formed with a retaining portion 534 that covers the second groove 533, and the tube 6 fitted into the second groove 533 is covered by the retaining portion 534 to prevent it from coming off. The tube 6 has a length that extends further downward from the lower end of the extending portion 532.

[0030] A strip-shaped folded portion 54 extending obliquely upward toward the abutment surface 554 is connected to the lower end of the extending portion 532. Because the folded portion 54 is elastically deformable, application of force to the folded portion 54 moves it closer to the extending portion 532. In other words, when pressure is applied to the folded portion 54, the angle between the folded portion 54 and the extending portion 532 becomes smaller.

[0031] The mounting member 5 configured as described above is integrally formed from a flexible material. The material constituting the mounting member 5 is not particularly limited, but it can be formed from materials such as urethane rubber, styrene-butadiene rubber, silicone rubber, and fluororubber. The hardness (international rubber hardness) of the mounting member 5 is preferably 60 to 100 IRHD, and more preferably 85 to 95 IRHD. The international rubber hardness can be measured, for example, by the test specified in JIS K 6253-2 (ISO 480).

[0032] <5. How to assemble and use the chemical supply device> Next, we will explain how to assemble and use the drug solution supply device using the components configured as described above. First, the drug solution guide member 3 is attached to the support body 4. That is, the drug solution guide member 3 is attached so as to cover the receiving portion 42 of the support body 4. At this time, the protrusion 34 of the drug solution guide member 3 engages with the engagement portion 45 of the support body 4, thereby fixing the drug solution guide member 3 to the support body 4.

[0033] Next, the mounting member 5 is attached to the support body 4. At this time, the method of attaching the mounting member 5 differs depending on the position of the lid body 12 of the water storage tank 1. For example, when the lid body 12 protrudes laterally from the tank body 11 as shown in FIG. 3, it is necessary to prevent the support body 4 from interfering with the lid body 12. Therefore, the receiving portion 51 of the mounting member 5 is fitted into the support body 4 so that the surface of the receiving portion 51 on the front panel 55 side of the mounting member 5 contacts the second long wall portion 411b of the support body 4. As a result, as shown in FIG. 11, the second long wall portion 411b of the support body 4 and the first extending surface 551 of the mounting member 5 are approximately flush with each other, thereby preventing interference between the support body 4 and the lid body 12.

[0034] Furthermore, since receiving portion 51 of mounting member 5 is positioned at a position offset from the center in the short-side direction of housing 41 of support body 4, discharge hole 512 of receiving portion 51 is not positioned directly below guide plate 46, and the cone-shaped bottom surface of recess 511 of receiving portion 51 is positioned instead. Therefore, the chemical solution running down guide plate 46 drips onto the cone-shaped bottom surface.

[0035] Next, the mounting member 5 is attached to the water storage tank. First, the lid 12 is shifted from the tank body 11 to expose the upper edge 111 of the tank body 11. Next, as shown in FIG. 12, the fixing portion 53 is attached so as to straddle the edge 111 of the tank body 11 from above. At this time, the abutment surface 554 of the mounting member 5 abuts against the outer surface of the edge 111 of the tank body 11, and the folded portion 54 presses against the inner wall surface of the edge 111. Therefore, the edge 111 of the tank body 11 is sandwiched between the abutment surface 554 and the folded portion 54, thereby fixing the mounting member 5 to the tank body 11. Next, as shown in FIG. 13, when the lid 12 is attached to the tank body 11, the fixing portion 53 is positioned between the first edge 121 and the second edge 122 of the lid 12. Additionally, the first edge portion 121 presses the curved surface 552 and the second extending surface 553 of the mounting member 5 (these portions constitute the installation surface of the present invention). However, since the tube 6 is fitted into the first groove 556, the first edge portion 121 is prevented from pressing the entire tube 6.

[0036] After the mounting member 5 is attached to the water storage tank 1 in this manner, the chemical solution container 2 is attached to the support member 4 as shown in FIG. 14 . The communicating tube 33 of the chemical solution guide member 3 is inserted into the thin film portion 222 of the cap 22 of the chemical solution container 2, allowing the chemical solution to flow through the communicating tube 33 and into the receiving portion 42 of the support member 4. The chemical solution then flows downward from the through hole 421 of the receiving portion 42 along the guide plate 46. The chemical solution drips from the lower end of the guide plate 46 into the recess 511 of the receiving portion 51 of the mounting member 5. At this time, the lower end of the guide plate 46 falls onto the cone-shaped bottom surface rather than the discharge hole 512 of the recess 511, and flows along the bottom surface and enters the discharge hole 512. The chemical solution that has entered the discharge hole 512 flows into the tube 6 and is supplied from the tube 6 to the flush water stored in the water storage tank 1.

[0037] In this way, the chemical solution stored in the water storage tank 1 together with the flush water has a fragrant and deodorizing effect due to the aromatic components. Furthermore, the chemical solution flowed from the water storage tank 1 into the toilet bowl during flushing cleans the toilet bowl, and also provides a fragrant and deodorizing effect. Note that the chemical supply device can also be attached to the water storage tank 1 after the chemical solution container 2 is attached to the support 4.

[0038] <6. Features> The chemical liquid supply device configured as above can provide the following effects. (1) This chemical liquid supply device has an attachment member 5 that is configured to be attachable to the edge 111 of the tank body 11, so that the chemical liquid supply device can be attached to a water storage tank that is not provided with a water supply tray. In addition, the attachment member 5 supports a flexible tube 6 that guides the chemical liquid from the chemical liquid container 2 to the water storage tank 1, so that the chemical liquid from the chemical liquid container 2 can be stably supplied to the water storage tank 1 by this tube 6.

[0039] (2) Because the fixing portion 53 and the folded portion 54 are deformable, the mounting member 5 can be attached to the edge 111 of the tank body 11 of various widths. The example in Fig. 14 described above shows a case where the edge 111 of the tank body 11 is narrow, that is, where the width of the edge 111 is shorter than the distance between the abutment surface 554 and the extension portion 532 of the fixing portion 53. However, when the edge 111 of the tank body 11 is wide, the mounting member 5 can be attached as follows.

[0040] 15, when the width of the edge 111 of the tank body 11 is somewhat wide, the folded portion 54 is pressed by the edge 111, and the folded portion 54 comes into contact with the extending portion 532 of the fixing portion 53. Then, the edge 111 of the tank body 11 is sandwiched between the abutting surface 554 and the folded portion 54. In this case, the edge 111 of the tank body 11 is sandwiched mostly by the elastic force of the fixing portion 53. In other words, when the width of the edge 111 of the tank body 11 is roughly the same as the distance between the extending portion 532 of the fixing portion 53 and the abutting surface 554, the edge 111 is sandwiched in this way.

[0041] 16, when the width of the edge 111 of the tank body 11 is wide, the curved fixing portion 53 is extended linearly, and the angle between the folded portion 54 and the extending portion 532 is widened so that they form approximately 90 degrees. This allows the edge 111 of the tank body 11 to be sandwiched between the abutment surface 554 and the folded portion 54. That is, when the width of the edge 111 of the tank body 11 is longer than the distance between the extending portion 532 of the fixing portion 53 and the abutment surface 554, the edge 111 is sandwiched in this manner.

[0042] 17, when the flange 18 extending inward is formed on the edge 111 of the tank body 11, the curved fixing portion 53 is extended linearly and placed along the upper surface of the flange 18. At this time, the folded portion 54 engages with the lower surface of the flange 18.

[0043] In this way, the mounting member 5 according to this embodiment can be attached to the edge 111 of the tank body 11 of various widths.

[0044] (3) Because fixing portion 53 has upwardly convex curved portion 531, fixing portion 53 can be positioned so as to ride over edge 111 of tank body 11. For example, as shown in FIG. 18 , if fixing portion 8 extends linearly, lid 12 may ride up on fixing portion 8, causing lid 12 to tilt, or mounting member 5 may tilt. In contrast, when fixing portion 53 is formed as described above, fixing portion 53 is positioned so as to ride over edge 111 of tank body 11, thereby suppressing interference between fixing portion 53 and the mating portion between tank body 11 and lid 12. As a result, lid 12 can be prevented from being positioned at an angle. Furthermore, because mounting member 5 can be prevented from being positioned at an angle, tilting of chemical solution container 2 can also be suppressed.

[0045] In addition to the water storage tank 1 of the above-described configuration, the mounting member 5 can also be attached to the following water storage tank. In the example of FIG. 19, only a first edge portion 121 extending downward is provided on the outer peripheral edge of the lid body 12, and this first edge portion 121 is in contact with the edge 111 of the tank body 11. In this case, the fixing portion 53 is positioned so as to straddle the edge 111 of the tank body 11, making it possible to attach it. Furthermore, although the first edge portion 121 of the lid body 12 presses the curved portion 531 of the fixing portion 53, the tube 6 is embedded in the second groove 533, so the first edge portion 121 does not press the entire tube 6. This prevents the flow of the chemical solution from being obstructed.

[0046] In the example of Fig. 20, a first edge 121 extending downward is provided on the outer peripheral edge of the lid body 12, and the width of this first edge 121 is wider than the edge 111 of the tank body 11. In addition, a protrusion 124 is formed at the lower end of the first edge 121 and is positioned on the inner surface side of the edge 111 of the tank body 11. In this case as well, the fixing part 53 is positioned so as to straddle the edge 111 of the tank body 11, and therefore can be attached.

[0047] In the example of Fig. 21, a first edge 121 extending downward is provided on the outer peripheral edge of the lid body 12, and the width of this first edge 121 is wider than the edge 111 of the tank body 11. Meanwhile, a protrusion 112 protruding upward is formed on the outer side of the upper end surface of the edge 111 of the tank body 11. Furthermore, a protrusion 125 is formed on the lower end of the first edge 121 and is positioned on the inner side of the edge 111 of the tank body 11, and this protrusion 125 is positioned inside the protrusion 112 of the tank body 11. In this case as well, the fixing part 53 is positioned so as to straddle the edge 111 of the tank body 11, and therefore can be attached.

[0048] In the example of Fig. 22, a first edge 121 extending downward is provided on the outer peripheral edge of the lid 12. Meanwhile, a protrusion 113 protruding upward is formed on the inside of the upper end surface of the edge 111 of the tank body 11. The first edge 121 is disposed on the outer surface side of the protrusion 113 of the tank body 11. In this case as well, the fixing part 53 is disposed so as to straddle the edge 111 of the tank body 11, and therefore can be attached.

[0049] In this way, the mounting member 5 according to this embodiment can be mounted to the water tank 1 in various forms.

[0050] (4) In the above example, since the lid body 12 protrudes from the tank body 11, the receiving portion 51 of the mounting member 5 is fitted into the support body 4 so that the second long wall portion 411b of the support body 4 faces the fixing portion 53 of the mounting member 5. This prevents interference between the support body 4 and the lid body 12. On the other hand, in a case where the side surface of the lid body 12 and the side surface of the tank body 11 are roughly flush with each other as shown in FIG. 23 , the receiving portion 51 of the mounting member 5 is fitted into the support body 4 so that the first long wall portion 411a of the support body 4 faces the fixing portion 53 of the mounting member 5. This causes the first long wall portion 411a of the support body 4 to protrude toward the water storage tank 1 more than the first extending surface 551 of the mounting member 5, preventing the support body 4 and the lid body 12 from becoming too far apart.

[0051] In this way, with the mounting member 5 and support body 4 according to this embodiment, the orientation of the support body 4 relative to the mounting member 5 can be changed depending on whether or not the lid body 12 protrudes. Therefore, it is possible to prevent interference between the lid body 12 and the support body 4, or to arrange the lid body 12 and the support body 4 so that the distance between them is not too great.

[0052] (5) Since the tube 6 is supported by the mounting member 5 so as to be positioned below the discharge hole of the receiving part, the following effect can be obtained. For example, as shown in Figure 24, if a part of the tube is positioned above the discharge hole of the receiving part, the medicinal liquid dripping from the discharge hole will accumulate between the part of the tube positioned above the discharge hole and the discharge hole, and there is a risk that the accumulated medicinal liquid will flow out all at once due to the siphon principle.

[0053] On the other hand, as shown in Figure 25, if the tube 6 is positioned below the discharge hole 512 of the receiving part 51, the chemical solution dripping from the guide plate 46 onto the receiving part 51 enters the tube 6 alternately with the air, so that the chemical solution can be supplied little by little from the tube 6 into the water storage tank 1.

[0054] (6) In the mounting member 5, the guide member 557 on which the tube 6 is placed, the curved surface 552, the second extending surface 553, and the fixing portion 53 are formed of curved or flat surfaces and do not have corners. This prevents the tube 6 from bending. As a result, the tube 6 is prevented from kinking, allowing the medicinal solution to flow smoothly through the tube 6.

[0055] (7) Guide plate 46 faces second long wall portion 411b inside housing 41 of support 4. Therefore, part of the chemical solution running down guide plate 46 volatilizes on guide plate 46. As a result, the aromatic component flows to the outside through opening 413 of the housing, thereby achieving an aromatic effect.

[0056] (8) Directly below the guide plate 46 of the support 4, the discharge hole 512 of the receiving portion 51 is not located, but the mortar-shaped bottom surface of the recess 511 of the receiving portion 51 is located. Therefore, the medicinal liquid running down the guide plate 46 does not directly enter the discharge hole 512, but drips onto the mortar-shaped bottom surface. As a result, part of the medicinal liquid evaporates on this bottom surface, thereby achieving an aromatic effect.

[0057] (9) Even if the lid 12 is installed on the mounting member 5 and the tube 6 is pressed by the lid 12, the tube 6 is not completely crushed because it is housed in the groove at that location (the installation portion). This allows the medicinal solution to flow smoothly into the tube 6. Furthermore, because the mounting member 5 is flexible, the groove is reduced in diameter when pressed by the lid 12. This allows the inner wall surface of the groove to tightly contact the tube 6, thereby firmly fixing the tube 6 to the groove.

[0058] <7. Variations> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the following modifications are possible. Furthermore, the gist of the following modifications can be combined as appropriate.

[0059] <7-1> In the above embodiment, there is a chemical solution guide member 3 and a support member 4, but as long as the chemical solution discharged from the chemical solution container 2 is supplied to the water storage tank 1 by a tube 6 and the chemical solution container 2 is supported directly or indirectly on the water storage tank 1 by the mounting member 5, the structure between the chemical solution container 2 and the mounting member 5 is not particularly limited.

[0060] <7-2> In the above embodiment, the fixing portion 53 of the mounting member 5 has the curved portion 531 that is convex upward, but the configuration of the fixing portion 53 is not particularly limited as long as it is formed convex upward so as to straddle the edge 111 of the tank body 11 from the abutting portion 52. Therefore, the fixing portion 53 may be formed in a U-shape with corners that are not curved. In addition, the folded portion 54 is not necessarily required.

[0061] <7-3> The tube 6 may be attached to any position on the attachment member 5, and does not necessarily have to be attached along the contact portion 52 and the fixing portion 53 as in the above embodiment. Therefore, it is not necessarily required to form a groove.

[0062] <7-4> The configuration of the contact portion 52 of the mounting member 5 is not particularly limited as long as the fixing portion 53 is attached.

[0063] <7-5> Mounting member 5 does not necessarily need to have receiving portion 51, but it is sufficient that the liquid medicine in liquid medicine container 2 can be supplied to tube 6. [Explanation of symbols]
