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 solution supply device that is easy to secure an installation location and can stably supply a chemical solution.

Means for Solving the Problems

[0006] The chemical agent supply device according to the present invention is a chemical solution supply device attached to a water storage tank of a toilet bowl having a tank body with an opening at the upper part and a lid for closing the opening of the tank body, and includes a chemical solution container for storing a chemical solution, a support for supporting the chemical solution container, a flexible tube for supplying the chemical solution in the chemical solution container to the water storage tank, and a mounting member for supporting the tube and configured to be attachable to the edge of the opening of the tank body. The support can be selectively attached to the mounting member at either a first position close to the water storage tank or a second position farther from the water storage tank than the first position.

[0007] In the above chemical solution supply device, the mounting member has a receiving portion attached to the support. The support has a first side surface, a second side surface opposite to the first side surface, a receiving space formed between the first side surface and the second side surface for receiving the receiving portion of the mounting member, and a positioning portion provided in the receiving space for positioning a part of the mounting member on the first side surface side.

[0008] In the above chemical solution supply device, the positioning portion can be formed by a fixing plate for the receiving space, and the receiving portion of the mounting member can be configured to be fixed between the fixing plate and the first side surface.

[0009] In the above chemical solution supply device, the mounting member includes a contact portion having a contact surface that can contact the outer surface of the tank body, and a fixing portion that straddles the edge of the tank body from the contact portion and extends downward along the inner surface of the tank body in an initial state. The receiving portion, the contact portion, and the fixing portion can be integrally formed of a flexible material.

[0010] In the above chemical solution supply device, the receiving part has a recess for receiving the chemical solution discharged from the chemical solution container, and the tube can be connected to the recess.

Advantages of the Invention

[0011] According to the present invention, since it has an attachment member configured to be attachable to the edge of the opening of the tank body, the chemical agent supply device can be attached to a water storage tank without a water receiving tray. Further, since a flexible tube for guiding the chemical solution in the chemical solution container to the water storage tank is supported by the attachment member, the chemical solution in the chemical solution container can be stably supplied to the water storage tank by this tube.

Mode for Carrying Out the Invention

[0013] Hereinafter, a chemical solution supply device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the chemical solution supply device according to this embodiment, FIG. 2 is an exploded side view of the chemical solution supply device in FIG. 1, and FIG. 3 is a cross-sectional view of the water storage tank.

[0014] As shown in FIGS. 1 and 2, this chemical solution supply device is a device for supplying a chemical solution to the water storage tank 1 of a toilet bowl, and includes a chemical solution container 2 in which the chemical solution is stored, a chemical solution guiding member 3 for discharging the chemical solution from the chemical solution container 2, a support 4 that supports the chemical solution container 2 and receives the chemical solution, and a mounting member 5 for mounting the support 4 to the water storage tank 1 of the toilet bowl.

[0015] As shown in FIG. 3, the target water storage tank 1 includes a tank body 11 in which flushing water is stored, and a lid body 12 that closes the upper opening of the tank body 11. The tank body 11 is provided with a first edge portion 121 that extends downward and a second edge portion 122 that is disposed at an interval inside the first edge portion 121 on the outer peripheral edge of the lid body 12. And the edge 111 of the upper opening of the tank body 11 is fitted between the first edge portion 121 and the second edge portion 122 of the lid body 12. Therefore, the lid body 12 is installed so as to protrude slightly outward from the outer peripheral surface of the tank body 11. The above-described mounting member 5 is mounted so as to be sandwiched between the tank body 11 and the lid body 12. Hereinafter, each member of the chemical solution supply device will be described in detail.

[0016] <1. Chemical Solution Container> FIG. 4 is a perspective view of the chemical solution container. As shown in FIG. 4, the chemical solution container 2 has a container body 21 formed in a transparent dome shape with a flat bottom surface, and the chemical solution is stored in the container body 21. A discharge port 211 is formed on the bottom surface of the container body 21, and a cap 22 is attached to the discharge port 211 before use. This cap 22 is composed of an annular main body portion 221 and a thin film portion 222 that closes the hole in the center thereof. When in use, the thin film portion 222 is broken to discharge the chemical solution.

[0017] The chemical solution contains one or more elements selected from the group including a cleaning agent, a disinfectant, a deodorant, and a fragrance, and may also contain a coloring agent. The chemical solution is mixed with the cleaning water stored in the water storage tank to provide the functions of the components contained in the chemical solution inside the toilet bowl or in the toilet room. For example, when the chemical solution contains a cleaning agent and a disinfectant, the toilet bowl can be cleaned and disinfected; when it contains a deodorant and a fragrance, unpleasant odors in the toilet room can be removed and a pleasant smell can be emitted.

[0018] <2. Chemical Solution Guiding Member> Figure 5 is a perspective view of the chemical solution guiding member. The chemical solution guiding member 3 is a member for guiding the chemical solution discharged from the chemical solution container 2 to the support 4. As shown in Figure 5, this chemical solution guiding member 3 has a rectangular upper surface portion 31 and side surface portions 32 extending downward from its peripheral edge. Also, an annular recess 311 is formed at the center of the upper surface portion 31, and the main body portion 221 of the cap 22 of the chemical solution container 2 is fitted into this recess 311. Further, inside the recess 311, a cylindrical communication pipe 33 with a sharp tip whose tip is cut obliquely is provided. This communication pipe 33 is designed to pierce the thin film portion 222 of the cap 22 of the chemical solution container 2. Thereby, the chemical solution in the chemical solution container 2 flows through the communication pipe 33 to the receiving portion 42 of the support 4 described below. Also, protrusions 34 are formed at opposing locations on the side surface portions 32.

[0019] <3. Support> Next, the support 4 will be described. Figure 6 is a perspective view of the support seen from above, and Figure 7 is a perspective view of the support seen from below. As shown in Figures 6 and 7, the support 4 has an elliptical housing 41 in plan view. And inside the space surrounded by the housing 41, there are a receiving portion 42 for attaching the chemical solution guiding member 3, a pair of support plates 43 arranged below the receiving portion 42 for supporting the receiving portion 42, and a fixing plate 44 for fixing the attachment member 5.

[0020] The housing 41 has a pair of long wall portions 411 extending in the longitudinal direction and a pair of short wall portions 412 extending in the short direction and being curved, and supports the chemical solution container 2 at their upper ends. Further, a plurality of openings 413 are formed in the housing 41, and the internal space of the housing 41 communicates with the outside through these openings 413. Note that the openings 413 may be omitted in some drawings.

[0021] A 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 attachment member 5 described later is arranged between these support plates 43.

[0022] Both sides of the fixing plate 44 are connected to the respective support plates 43 and extend in the longitudinal direction between these support plates 43. Further, the fixing plate 44 is arranged on the side of one long wall portion (hereinafter referred to as the first long wall portion 411a, and the other long wall portion is referred to as the second long wall portion 411b) rather than the center in the short direction of the internal space. Then, the receiving portion 51 of the attachment member 5 described later is fitted between the second long wall portion 411b and the fixing plate 44. More specifically, the distance between the second long wall portion 411b and the fixing plate 44 is slightly shorter than the length in the short direction of the receiving portion 51. Therefore, the flexible receiving portion 51 is press-fitted between the second long wall portion 411b and the fixing plate 44.

[0023] At the upper ends of the support plates 43, engaging portions 45 are provided which engage with the projecting portions 34 on both sides of the chemical liquid guiding member 3 while being elastically deformed. Between these engaging portions 45, a receiving portion 42 for receiving the chemical liquid is disposed. The receiving portion 42 is formed in a cup shape with a rectangular shape in plan view, and a through hole 421 is formed at the center of the bottom surface. And the outer edge of the receiving portion 42 is adapted to enter inside the side surface portion 32 of the chemical liquid guiding member 3. Further, a guide plate 46 extending downward is formed from the bottom surface of the receiving portion 42, and the chemical liquid passing through the through hole 421 flows downward along the guide plate 46. Note that the guide plate 46 is disposed near the center in the lateral direction of the housing 41 and faces the second long wall portion 411b.

[0024] <4. Mounting Member> FIG. 8 is a side view of the mounting member, FIG. 9 is a perspective view of the mounting member as viewed from above, and FIG. 10 is a perspective view of the mounting member as viewed from the back. As shown in FIGS. 8 to 10, the mounting member 5 includes a receiving portion 51 attached to the support 4, a contact portion 52 connected to the lower end surface of the receiving portion 51, a fixing portion 53 extending so as to straddle the edge 111 of the tank body 11 from the contact portion 52, and a folding portion 54 extending from the end of the fixing portion 53 toward the contact portion 52 side, and these are integrally formed of a flexible material. Further, a known flexible tube 6 is attached to the mounting member 5.

[0025] The receiving portion 51 is formed in a block shape with an octagonal shape in plan view, and a rectangular recess 511 is formed at the center of the upper surface. The bottom surface of this recess 511 is formed in a mortar shape, and a discharge hole 512 is formed at the lowermost part of the bottom surface. A rod-shaped member 513 having a through hole communicating with the discharge hole 512 is attached to a portion where the recess 511 is formed on the lower surface of the receiving portion 51. This rod-shaped member 513 is inserted into the upper end of the tube 6, and the chemical liquid accumulated in the recess 511 flows into the tube 6 through the discharge hole 512 and the through hole.

[0026] The contact portion 52 has a front panel 55 extending downward from the receiving portion 51 and a pair of side panels 56 connected to both sides of the front panel 55, and the front panel 55 is supported by the pair of side panels 56. The front panel 55 has a first extending surface 551 extending downward from the outer peripheral surface of the receiving portion 51 on the side of the water storage tank 1, a curved surface 552 curved downwardly convex from the lower end of the first extending surface 551, a second extending surface 553 extending obliquely upward from the curved surface 552, and a contact surface 554 extending downward from the end of the second extending surface 553. Further, in each side panel 56, the edge on the side of the water storage tank 1 is formed along the first extending surface 551, the curved surface 552, the second extending surface 553, and the contact surface 554. On the other hand, in each side panel 56, the edge on the side opposite to the water storage tank 1 extends obliquely linearly from the lower end portion of the receiving portion 51 to the lower end portion of the contact surface 554.

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

[0028] Also, in the front panel 55, a plate-shaped guide member 557 is arranged on the back surface of the first extending surface 551. This guide member 557 extends upward from the upper edge of the through hole 555 and is arranged with a gap from the rod-shaped member 513. Further, the edge of the guide member 557 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 arranged along 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 the initial state, the fixing portion 53 is formed in a strip shape having a curved portion 531 that extends upwardly convex from the upper end of the second extending surface 553 described above, and an extending portion 532 that extends downward from the tip of the curved portion 531. A second groove 533 that is continuous with the first groove 556 formed in the second extending surface 553 is formed in the fixing portion 53. The second groove 533 has the same cross-sectional shape as the first groove 556 and extends across the curved portion 531 and the extending portion 532. Further, a retaining portion 534 that covers the second groove 533 is formed in the extending portion 532, and the tube 6 fitted into the second groove 533 is covered by the retaining portion 534 so as not to come off. Note that the tube 6 has a length that extends further downward from the lower end of the extending portion 532.

[0030] A strip-shaped folded-back portion 54 that extends obliquely upward toward the abutting surface 554 is connected to the lower end of the extending portion 532. Since the folded-back portion 54 is elastically deformable, it comes close to the extending portion 532 side by applying a force. That is, when the folded-back portion 54 is pressed, the angle formed by the folded-back portion 54 and the extending portion 532 becomes smaller.

[0031] The mounting member 5 configured as described above is integrally formed of a flexible material. The material constituting the mounting member 5 is not particularly limited, but can be formed of materials such as urethane rubber, styrene-butadiene rubber, silicone rubber, and fluororubber. Further, 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 by a test defined in, for example, JIS K 6253-2 (ISO480).

[0032] <5. Assembly Method and Usage Method of Chemical Solution Supply Device> Next, an assembly method and a usage method of the chemical solution supply device using the respective members configured as described above will be explained. First, the chemical solution guiding member 3 is attached to the support 4. That is, the chemical solution guiding member 3 is attached so as to cover the receiving portion 42 of the support 4. At this time, the protrusion 34 of the chemical solution guiding member 3 engages with the engaging portion 45 of the support 4, whereby the chemical solution guiding member 3 is fixed to the support 4.

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

[0034] Further, since the receiving portion 51 of the attachment member 5 is disposed at a position deviated from the center in the short side direction of the housing 41 of the support 4, the discharge hole 512 of the receiving portion 51 is not disposed directly below the guide plate 46, and the mortar-shaped bottom surface of the recess 511 of the receiving portion 51 is disposed. Therefore, the chemical solution flowing along the guide plate 46 is dropped onto the mortar-shaped bottom surface.

[0035] Next, attach the mounting member 5 to the water storage tank. First, shift the lid 12 from the tank body 11 to expose the edge 111 at the upper end of the tank body 11. Next, as shown in FIG. 12, attach the fixing portion 53 so as to straddle the edge 111 of the tank body 11 from above. At this time, the contact surface 554 of the mounting member 5 contacts the outer surface of the edge 111 of the tank body 11, and the inner wall surface of the edge 111 is pressed by the folded-back portion 54. Therefore, the edge 111 of the tank body 11 is sandwiched between the contact surface 554 and the folded-back portion 54, whereby the mounting member 5 is fixed to the tank body 11. Subsequently, as shown in FIG. 13, when the lid 12 is attached to the tank body 11, the fixing portion 53 is disposed between the first edge portion 121 and the second edge portion 122 of the lid 12. Further, the first edge portion 121 presses around the curved surface 552 and the second extending surface 553 of the mounting member 5 (this portion constitutes the installation surface of the present invention). However, since the tube 6 is fitted into the first groove 556, the entire tube 6 is prevented from being pressed by the first edge portion 121.

[0036] Thus, after attaching the mounting member 5 to the water storage tank 1, as shown in FIG. 14, attach the chemical solution container 2 to the support 4. Since the communication pipe 33 of the chemical solution guiding member 3 is inserted into the thin film portion 222 of the cap 22 of the chemical solution container 2, the chemical solution flows into the receiving portion 42 of the support 4 through the communication pipe 33. Then, this chemical solution flows downward from the through hole 421 of the receiving portion 42 along the guide plate 46. The chemical solution is dropped 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 not into the discharge hole 512 of the recess 511 but onto the mortar-shaped bottom surface, and while flowing on the bottom surface, it 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 washing water stored in the water storage tank 1.

[0037] Thus, the chemical solution stored in the water storage tank 1 together with the washing water exhibits an aromatic deodorizing effect due to the aromatic component. Further, the toilet is washed by the chemical solution flowing from the water storage tank 1 to the toilet during flushing, and an aromatic deodorizing effect can also be obtained. Note that after attaching the chemical solution container 2 to the support 4, a chemical agent supply device can also be attached to the water storage tank 1.

[0038] <6. Features> In the chemical liquid supply device configured as described above, the following effects can be obtained. (1) Since this chemical liquid supply device has the attachment member 5 configured to be attachable to the edge 111 of the tank body 11, the chemical agent supply device can be attached to a water storage tank not provided with a water receiving tray. Further, since the attachment member 5 supports the flexible tube 6 that guides the chemical liquid in the chemical liquid container 2 to the water storage tank 1, the chemical liquid in the chemical liquid container 2 can be stably supplied to the water storage tank 1 by this tube 6.

[0039] (2) Since the fixing portion 53 and the folding portion 54 are deformable, the attachment member 5 can be attached to the edges 111 of the tank body 11 with various widths. In the example of FIG. 14 described above, the case where the width of the edge 111 of the tank body 11 is narrow, that is, the case where the width of the edge 111 is shorter than the distance between the contact surface 554 and the extending portion 532 of the fixing portion 53 was shown. However, when the width of the edge 111 of the tank body 11 is wide, the attachment member 5 can be attached as follows.

[0040] As shown in FIG. 15, when the width of the edge 111 of the tank body 11 is slightly wide, the folding portion 54 is pressed by the edge 111, and the folding portion 54 contacts the extending portion 532 of the fixing portion 53. Then, the edge 111 of the tank body 11 is sandwiched between the contact surface 554 and the folding portion 54. In this case, the edge 111 of the tank body 11 is generally sandwiched by the elastic force of the fixing portion 53. That is, when the width of the edge 111 of the tank body 11 is approximately equal to the distance between the extending portion 532 of the fixing portion 53 and the contact surface 554, it is sandwiched in this way.

[0041] As shown in Fig. 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-back portion 54 and the extending portion 532 is widened so that the two form an angle of approximately 90 degrees. Thereby, the edge 111 of the tank body 11 can be sandwiched between the contact surface 554 and the folded-back 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 contact surface 554, it is clamped in such a way.

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

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

[0044] (3) Since the fixing portion 53 has an upwardly convex curved portion 531, the fixing portion 53 can be arranged so as to straddle the edge 111 of the tank body 11. For example, as shown in Fig. 18, when the fixing portion 8 extends linearly, there is a possibility that the lid body 12 rides on the fixing portion 8, the lid body 12 tilts, or the mounting member 5 tilts. On the other hand, when the fixing portion 53 is formed as described above, since the fixing portion 53 is arranged so as to straddle the edge 111 of the tank body 11, interference between the fitting portion between the tank body 11 and the lid body 12 and the fixing portion 53 can be suppressed. As a result, it is possible to suppress the lid body 12 from being tilted. In addition, since it is possible to suppress the mounting member 5 from being tilted, it is also possible to suppress the chemical liquid container 2 from being tilted.

[0045] In addition to the water storage tank 1 of the above-described form, the attachment member 5 can also be attached to the following water storage tanks. In the example of FIG. 19, only the first edge portion 121 extending downward is provided at the outer peripheral edge of the lid body 12, and the first edge portion 121 is in contact with the edge 111 of the tank body 11. In this case, since the fixing portion 53 is arranged so as to straddle the edge 111 of the tank body 11, it can be attached. Further, although the first edge portion 121 of the lid body 12 presses around the curved portion 531 of the fixing portion 53, since the tube 6 is embedded in the second groove 533, the entire tube 6 is suppressed from being pressed by the first edge portion 121. Therefore, the flow of the chemical solution is prevented from being inhibited.

[0046] In the example of FIG. 20, a first edge portion 121 extending downward is provided at the outer peripheral edge of the lid body 12, but the width of the first edge portion 121 is wider than the edge 111 of the tank body 11. Further, a protrusion 124 arranged on the inner surface side of the edge 111 of the tank body 11 is formed at the lower end of the first edge portion 121. Also in this case, since the fixing portion 53 is arranged so as to straddle the edge 111 of the tank body 11, it can be attached.

[0047] In the example of FIG. 21, a first edge portion 121 extending downward is provided at the outer peripheral edge of the lid body 12, but the width of the first edge portion 121 is wider than the edge 111 of the tank body 11. On the other hand, a protrusion 112 protruding upward is formed outside the upper end surface of the edge 111 of the tank body 11. Further, a protrusion 125 arranged on the inner surface side of the edge 111 of the tank body 11 is formed at the lower end of the first edge portion 121, and this protrusion 125 is arranged inside the protrusion 112 of the tank body 11. Also in this case, since the fixing portion 53 is arranged so as to straddle the edge 111 of the tank body 11, it can be attached.

[0048] In the example of FIG. 22, a first edge portion 121 extending downward is provided at the outer peripheral edge of the lid body 12. On the other hand, a protrusion 113 protruding upward is formed inside the upper end surface of the edge 111 of the tank body 11. And the first edge portion 121 is arranged on the outer surface side of the protrusion 113 of the tank body 11. Also in this case, since the fixing portion 53 is arranged so as to straddle the edge 111 of the tank body 11, it can be attached.

[0049] Thus, the attachment member 5 according to the present embodiment can be attached to the water storage tank 1 in various modes.

[0050] (4) In the above example, since the lid 12 protrudes from the tank body 11, the receiving portion 51 of the attachment member 5 is fitted into the support 4 so that the second long wall portion 411b of the support 4 faces the fixing portion 53 side of the attachment member 5 (second position). This suppresses interference between the support 4 and the lid 12. On the other hand, when the side surface of the lid 12 and the side of the tank body 11 are substantially flush as shown in FIG. 23, the receiving portion 51 of the attachment member 5 is fitted into the support 4 so that the first long wall portion 411a of the support 4 faces the fixing portion 53 side of the attachment member 5 (first position). Thereby, since the first long wall portion 411a of the support 4 protrudes toward the water storage tank 1 side rather than the first extending surface 551 of the attachment member 5, it is possible to suppress the distance between the support 4 and the lid 12 from being too large.

[0051] Thus, in the attachment member 5 and the support 4 according to the present embodiment, the orientation of the support 4 with respect to the attachment member 5 can be changed according to the presence or absence of the protrusion of the lid 12. Therefore, it is possible to prevent interference between the lid 12 and the support 4, or to arrange them so that the distance between the lid 12 and the support 4 does not open too much.

[0052] (5) Since the tube 6 is supported by the attachment member 5 so as to be positioned below the discharge hole of the receiving portion, the following effect can be obtained. For example, as shown in FIG. 24, when a part of the tube is positioned above the discharge hole of the receiving portion, the chemical solution dropped from the discharge hole accumulates between the portion of the tube positioned above the discharge hole and the discharge hole. Therefore, there is a possibility that the accumulated chemical solution may flow out all at once due to the siphon principle.

[0053] On the other hand, as shown in FIG. 25, if the tube 6 is located below the discharge hole 512 of the receiving portion 51, the chemical solution dripping from the guide plate 46 to the receiving portion 51 enters the tube 6 alternately with 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, since the guide member 557, the curved surface 552, the second extending surface 553, and the fixing portion 53 on which the tube 6 is disposed are formed by a curved surface or a flat surface, they do not have corners. Therefore, the tube 6 can be prevented from bending. As a result, kinking of the tube 6 can be suppressed, so that the chemical solution can flow smoothly in the tube 6.

[0055] (7) The guide plate 46 faces the second long wall portion 411b inside the housing 41 of the support 4. Therefore, a part of the chemical solution passing through the guide plate 46 volatilizes on the guide plate 46. Therefore, since the aromatic component flows out to the outside from the opening 413 of the housing, an aromatic effect can be obtained.

[0056] (8) Immediately below the guide plate 46 of the support 4, the discharge hole 512 of the receiving portion 51 is not disposed, and the mortar-shaped bottom surface of the concave portion 511 of the receiving portion 51 is disposed. Therefore, the chemical solution passing through the guide plate 46 does not directly enter the discharge hole 512 but is dropped onto the mortar-shaped bottom surface. Therefore, a part of the chemical solution volatilizes on this bottom surface, so that an aromatic effect can be obtained.

[0057] (9) Even if the lid body 12 is installed on the mounting member 5 and the tube 6 is pressed by the lid body 12, the tube 6 is accommodated in the groove at that location (installation portion), so it is not completely crushed. Therefore, the chemical solution can flow smoothly in the tube 6. Further, since the mounting member 5 has flexibility, when pressed by the lid body 12, the groove contracts in diameter. As a result, the inner wall surface of the groove and the tube 6 are in close contact with each other, so that the tube 6 can be firmly fixed to the groove.

[0058] <7. Modification Example> The above describes one embodiment of the present invention. However, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit thereof. For example, the following modifications are possible. Also, the gists of the following modification examples can be combined as appropriate.

[0059] <7-1> In the above embodiment, the chemical solution guiding member 3 and the support 4 are provided. However, as long as the chemical solution discharged from the chemical solution container 2 is supplied to the water storage tank 1 by the tube 6, the chemical solution container 1 is supported by the support 4, and the attachment member 5 can be attached to the support 4, the configuration of the support 4 can be appropriately changed, and the chemical solution guiding member 3 is not necessarily required.

[0060] <7-2> In the above embodiment, in order for the support 4 to be able to take the first position and the second position of the present invention, a fixing plate 44 is provided in the internal space of the support 4, and the receiving portion 51 of the attachment member 5 is fitted between the fixing plate 44 and the second long wall portion 411b of the housing 4. However, as long as the support 4 can take the first position and the second position of the present invention, the configuration of the support 4 is not particularly limited. For example, it is sufficient if a positioning portion is provided such that the receiving portion 51 of the attachment member 5 can move in the short direction in the internal space of the support 4. Alternatively, the support 4 may be rotatable with respect to the attachment member 5 and may have a structure that can thereby take the first and second positions.

[0061] <7-3> In the attachment member 5, the configuration for attaching to the water storage tank 1 is not particularly limited, and it is sufficient if at least the attachment member 5 is configured to be attached between the tank body 11 and the lid body 12 of the water storage tank 1. Therefore, for example, the configuration of the fixing portion 53 can be appropriately changed.

[0062] <7-4> The tube 6 may be attached to any position of the attachment member 5, and may not be attached along the contact portion 52 and the fixing portion 53 as in the above embodiment.
