BACKGROUND OF THE INVENTION
The present invention relates to a chemical supply device that is disposed in a hand-washing section above a water storage tank in a flush toilet and supplies chemical liquid into the water storage tank together with water supplied to the hand-washing section.
[0002]
[Prior art]
An example of this type of chemical supply tool is disclosed in Patent Document 1. As shown in FIG. 10, the chemical solution supply device includes a chemical solution container 101 and a support body 102 that supports the chemical solution container 101, and the impregnated body 103 disposed in the support body 102 is discharged from the chemical solution container 101. Absorbed chemicals. The upper part of the support 102 is closed by the chemical solution container 101 and the cover member 104. In addition, a plurality of openings and a guide member 105 are formed at the bottom of the support 102, and the running water supplied to the hand-washing portion 106 of the water storage tank is guided to the opening by the guide member 105. . And the water which flowed in into the support body 102 from the opening contacts the impregnated body 103 to wash away the chemical solution and flows into the water storage tank.
[0003]
In the chemical solution supply device configured as described above, the cover member 104 prevents the water flowing down from above the chemical solution container 101 from coming into direct contact with the impregnated body 103, and an opening and a guide member 105 at the bottom of the support body 102. By providing this, excessive inflow of water into the support 102 is restricted.
[0004]
However, in this chemical solution supply tool, the water that has flowed into the support body 102 is in direct contact with the impregnated body 103, so that the chemical liquid absorbed in the impregnated body 103 is diluted with the flowing water. Therefore, there is a problem that the chemical solution is easily discharged from the chemical solution container 101 more than necessary to supplement the diluted chemical solution, and the chemical solution in the container 101 is rapidly reduced.
[0005]
Therefore, the applicant of the present application provides a chemical solution supply tool that addresses such a problem.
Hereinafter, this chemical solution supply tool will be described.
[0006]
FIG. 11 is a front view (a) and a side view (b) of the chemical liquid supply tool, and FIG. 12 is an exploded view of the chemical liquid supply tool.
[0007]
As shown in FIGS. 11 and 12, this chemical liquid supply tool includes a chemical liquid container 51 that stores an aromatic cleaning agent, a discharge pipe 53 that discharges the aromatic cleaning agent from the chemical liquid container 51, and an aromatic cleaning that passes through the discharge pipe 53. And a chemical supply member 55 for guiding the agent to a predetermined position. The discharge pipe 53 is formed integrally with an adjusting member 57 described later, and is disposed between the chemical liquid container 51 and the chemical liquid supply member 55. And these members are supported by the cup-shaped support body 59 arrange | positioned at a hand-washing part.
[0008]
FIG. 13 is a plan view (a) and a side view (b) of the chemical solution supply member. As shown in the figure, the chemical solution supply member 55 is made of plastic, and is inclined downward from a base 61 where one end of the discharge pipe 53 substantially contacts, and both side edges (upper and lower sides in the figure) of the base 61. A pair of guide plates 63 is provided. A plurality of grooves 65 through which the fragrance cleaning agent can flow are formed in the width direction (left and right direction in the figure) in the vicinity of the portion where the discharge pipe 53 abuts in the base 61 and the center of these grooves 65. The guide groove 67 is configured by the one arranged in the above. The guide groove 67 extends across the base portion 61 to the end portions of both guide plates 63, and guides the aromatic cleaning agent from the base portion 61 to the guide plate 63 side. As shown in FIG. 11, the end portion of each guide plate 63 protrudes from an opening 69 formed from the bottom surface to the side surface of the support body 59.
[0009]
FIG. 14 is an enlarged cross-sectional view of the adjustment member 57. As shown in the figure, the adjustment member 57 is integrally formed with the discharge pipe 53 and is formed in a U-shaped box shape when viewed from the front, and a connection portion connected to the mouth portion 52 at the lower end of the chemical solution container 51 at the center upper portion thereof. 56 is provided. The connection part 56 is formed in a cylindrical shape with a sharp upper end, and is arranged so as to surround the periphery of the discharge pipe 53. Further, the adjustment member 57 forms a storage chamber 57 a with the opened lower end edge abutting against the base 61 of the chemical solution supply member 55. The fragrance cleaning agent that has passed through the groove 65 from the discharge pipe 53 is stored in the storage chamber 57 a, and part of the fragrance cleaning agent flows through the guide groove 67 to the guide plate 63. Air circulation holes 71 communicating with the outside are formed at both upper ends of the storage chamber 57a, and a plurality of communication holes 73 are formed around the discharge pipe 53 to allow the chemical solution container 51 and the storage chamber 57a to communicate with each other. .
[0010]
As shown in FIG. 11, a plurality of legs 75 are formed on the bottom surface of the support body 59, and these legs 75 are inserted into drains formed in the hand-washing part. Thereby, a chemical | medical solution supply tool can be stably installed on a hand-washing part, and it can prevent falling down by flowing water.
[0011]
The chemical solution feeder configured as described above operates as follows. That is, the fragrance cleaning agent in the chemical solution container 51 flows out of the chemical solution container 51 through the discharge pipe 53 and is stored in the storage chamber 57 a through the groove 65, and a part thereof is guided through the guide groove 67. To 63. The aromatic cleaning agent on the guide plate 63 is washed away by the water supplied at the time of flushing and flows into the water storage tank. Note that the water supplied at this time is in direct contact with the guide plate 63 in any case where the water flows over the hand-washing portion from the side of the chemical solution supply tool or flows down from above the chemical solution supply tool. Rinse away.
[0012]
Thus, in this chemical solution supply tool, since the running water does not directly contact the base 61 of the chemical solution supply member 55 but contacts the guide plate 63 to wash away the fragrance cleaning agent, unlike the chemical solution supply device described in Patent Document 1. Further, it is possible to prevent the aromatic cleaning agent from being excessively discharged from the chemical solution container. The excessive discharge of the fragrance cleaning agent is limited because the flow of the fragrance cleaning agent to the guide plate 63 mainly passes through the guide groove 67 and the adjustment member 57 is provided. .
[0013]
Further, as will be described below, the adjustment member 57 performs a buffering action when a pressure change occurs in the chemical solution container 51 due to a temperature change. For example, when the room temperature rises and the chemical container 51 is warmed, the air in the container 51 expands and the container 51 becomes positive pressure. In this case, the fragrance cleaning agent in the container 51 is pushed out and discharged, but most of the fragrance cleaning agent flows into the storage chamber 57a through the discharge pipe 53 and the groove 65, and therefore toward the guide plate 63. It is prevented from continuing to flow out. On the other hand, for example, when the temperature of the chemical solution container is lowered by flowing water and the temperature is lowered, the air in the chemical solution container 51 contracts and becomes negative pressure. Thereby, the aromatic cleaning agent in the storage chamber 57 a is pulled back into the chemical solution container 51 through the communication hole 73. Therefore, it is possible to prevent the aromatic cleaning agent on the guide plate 63 from returning to the container 51 side. As described above, since the adjustment member 57 circulates between the chemical container 51 and the storage chamber 57a, most of the aromatic cleaning agent flows even when the pressure change occurs in the chemical container 51 due to the temperature change. It is possible to prevent the aromatic cleaning agent in the container 51 from flowing out excessively or from being restricted from flowing out.

[0015]
[Problems to be solved by the invention]
However, the chemical solution supply tool has the following problems. That is, when the flowing water flows to the chemical solution supply device by flushing, the flowing water not only washes the fragrance cleaning agent on the guide plate 63, but part of the flowing water may flow along the guide plate 63 into the adjusting member 57. . At this time, if the temperature of flowing water is lower than room temperature, the chemical solution container 51 is cooled and the inside of the container 51 becomes negative pressure. Therefore, not only the aromatic cleaning agent in the storage chamber 57a but also the flowing water that has traveled through the guide plate 63 is sucked into the container 51, and the water that has entered the container 51 is mixed with the aromatic cleaning agent. Then, after flushing, the chemical solution container 51 cooled by running water is gradually warmed to room temperature. Thereby, the inside of the container 51 becomes a positive pressure, and the aromatic cleaning agent is discharged.
[0016]
When the change in the pressure in the container as described above is repeated, the viscosity of the aromatic cleaning agent is lowered by the flowing water. And when the viscosity of an aromatic cleaning agent will be in the state close | similar to water, discharge | emission of an aromatic cleaning agent will be accelerated | stimulated at a stretch. Therefore, at the initial stage of use of the chemical supply tool, since the flowing water flows into the container 51 every flush, the decrease in the fragrance cleaning agent in the container 51 is very moderate at first glance. As described above, since the viscosity of the fragrance cleaning agent decreases, the fragrance cleaning agent in the container 51 tends to flow out and decreases at a stroke. As a result, there arises a problem that the user notices a decrease in the chemical solution remarkably in the later stage of use.
[0017]
On the other hand, even when the temperature of running water is higher than room temperature, the same problem occurs. In this case, since flowing water warms the chemical solution container 51, the inside of the container 51 becomes a positive pressure, and the discharge of the aromatic cleaning agent is promoted. After flushing, the chemical solution container 51 heated by running water is gradually cooled at room temperature, and the inside of the container 51 becomes negative pressure. At this time, if running water at the time of flushing remains around the discharge pipe 53 in the storage chamber 57a, this water is sucked into the container 51, and the viscosity of the fragrance cleaning agent decreases.
[0018]
When the above is repeated, although the amount of water entering the container is small compared with the case where the temperature of the flowing water is lower than room temperature, the decrease in the viscosity surely proceeds. Further, as the discharge of the aromatic cleaning agent from the container 51 proceeds and the volume of the air occupying the container 51 increases, the discharge amount of the aromatic cleaning agent tends to increase in the later stage of use. That is, since the volume of the air in the container 51 is small in the initial stage of use, the amount of expansion of the air is small and the discharge amount of the aromatic cleaning agent is not large. However, since the volume of the air in the container 51 becomes large in the later stage of use, the amount of expansion of the air due to the temperature change is also large, thereby increasing the pressure with which the air in the container 51 presses the fragrance cleaning agent. Therefore, the discharge amount of the fragrance cleaning agent is increased in the later stage of use. From the above, in addition to the decrease in the viscosity of the fragrance cleaning agent, the discharge amount of the fragrance cleaning agent in the latter stage of use increases due to an increase in the pressure as described above. Thereby, the problem that the usable time of a chemical | medical solution supply tool reduces arises.
[0019]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a chemical solution supply device that can prevent the discharge amount of the chemical solution from increasing rapidly in the later stage of use.
[0020]
[Means for Solving the Problems]
The present invention has been made in order to solve the above-described problem, and is provided in a hand-washing section at the upper part of a water storage tank in a flush toilet, and supplies chemical liquid to the water storage tank together with water supplied to the hand-washing section. A chemical container in which a chemical solution is stored and a mouth portion is formed at a lower end, a chemical solution in the chemical solution container is discharged, a discharge portion connected to the mouth portion, and an end portion of the discharge portion A chemical solution supply member disposed oppositely, and a support member that supports the chemical solution container and the chemical solution supply member and is disposed on the hand-washing portion, the chemical solution supply member receives the chemical solution discharged from the discharge portion. A base part, a holding part that is spaced apart from the base part and can hold a chemical solution, and a connecting part that extends between the base part and the holding part and connects them to guide the chemical solution on the base part to the holding part, The holding part is located above the hand washing part. It is intended to provide a chemical liquid supply device, characterized in that is disposed at a position capable of direct contact with the water supplied flows down from.
[0021]
According to the said structure, the base part and holding | maintenance part in a chemical | medical solution supply member are connected by the connection part extended thinly between them. Therefore, a predetermined space is formed between the base portion and the holding portion, and when the flowing water of the hand-washing portion is washed away from the holding portion by this space, the path to the base side of the flowing water is blocked and the flowing water is Inflow to the base side can be prevented. Thereby, even if the inside of a chemical | medical solution container becomes a negative pressure by temperature change, it can prevent that flowing water is sucked in and can prevent that the viscosity of a chemical | medical solution falls. As a result, it is possible to prevent the discharge amount of the chemical liquid from rapidly increasing in the latter stage of use of the chemical liquid supply tool.
[0022]
In addition, although the holding part is disposed at a position where it can come into contact with the water supplied by flowing down directly from above to the hand-washing part as described above, in addition to this, the hand-washing part is placed from the side of the chemical supply tool. It can also contact the flowing water.
[0023]
Moreover, the said connection part inclines below from the said base, and the said holding | maintenance part shall be arrange | positioned under the said base. According to this configuration, since the base portion is disposed above the holding portion, it is difficult for flowing water to flow toward the base portion, and the position of the holding portion is lowered, so that the chemical solution is easily washed away by the flowing water.
[0024]
At this time, an inclined portion that is disposed along an edge of the base portion that faces the holding portion and that is inclined downward at an inclination angle smaller than that of the connecting portion can be further provided. By doing so, the inclined portion becomes a shielding wall and the water flowing from below to the base can be blocked, and the flowing water can be more reliably prevented from flowing into the chemical solution container.
[0025]
Moreover, a some connection part can also be provided between the said base and a holding | maintenance part. If it does in this way, since a holding | maintenance part is stably hold | maintained with respect to a base, it can prevent that a connection part deform | transforms, for example, and the chemical | medical solution on a holding | maintenance part flows out unexpectedly.
[0026]
Moreover, the said base part shall be equipped with the recessed part which can distribute | circulate a chemical | medical solution in the position facing the edge part of the said discharge part, and shall be comprised so that a chemical | medical solution may flow to the said connection part side via the said recessed part. Can do. If comprised in this way, since the distribution | circulation amount of a chemical | medical solution is restrict | limited by a recessed part, it can prevent that a chemical | medical solution flows out excessively.
[0027]
At this time, an open lower end edge is brought into contact with the base portion to form a storage chamber for storing the chemical solution discharged from the discharge portion, and the amount of the chemical solution flowing from the chemical solution container to the holding portion is adjusted. It is preferable that the adjusting member further includes an air flow hole formed in the storage chamber and a communication hole that communicates the storage chamber and the container body.
[0028]
In this configuration, the adjustment member acts as a buffer when a pressure change occurs in the chemical container due to a temperature change. For example, when the room temperature rises and the chemical solution container is warmed, the air in the container expands and the inside of the container becomes positive pressure. In this case, the chemical liquid in the container is pushed out and discharged, but most of the chemical liquid flows into the storage chamber through the discharge portion and the recess, and therefore, it is prevented from continuing to flow out to the holding portion side. On the other hand, when the temperature of the chemical container is lowered by being cooled by flowing water and the air in the chemical container is contracted to a negative pressure, the chemical in the storage chamber is drawn back into the chemical container through the communication hole. Therefore, it can prevent that the chemical | medical solution by the side of a holding | maintenance part is returned to the container side. As described above, the adjustment member has an excessive amount of chemical solution in the chemical solution container because most of the chemical solution circulates between the chemical solution container and the storage chamber even when a pressure change occurs in the chemical solution container due to a temperature change. It is possible to prevent the spillage or the spillage from being restricted.
[0029]
Further, at least a part of the concave portion is constituted by a groove, and at least a part of the groove may extend from the base portion to the holding portion along the connecting portion. Thereby, the chemical solution in the chemical solution container is easily guided from the base portion to the holding portion, and a predetermined amount of the chemical solution can be reliably guided to the holding portion.
[0030]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a chemical supply tool according to the present invention will be described with reference to the drawings. The chemical supply device according to this embodiment is greatly different from the conventional example in the configuration of the chemical supply member, and the other configuration is substantially the same as the conventional example. Therefore, in the following description, the chemical supply member The same components are denoted by the same reference numerals, and the description thereof is omitted. In the following description, the vertical and horizontal directions are shown with reference to the drawing sheet.
[0031]
(First embodiment)
A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view (a) and a side view (b) showing a chemical solution supply member of a chemical solution supply tool according to the present embodiment.
[0032]
As shown in the figure, the chemical solution supply member 1 according to the present embodiment is formed in a plate shape with a material such as plastic, and is separated from the base 3 facing the discharge pipe (discharge portion) 53 and the base 3. And a pair of connecting portions 7 for connecting the base portion 3 and the holding portion 5 to each other.
[0033]
The base 3 is formed in a rectangular shape, and forms a storage chamber 57a by contacting the adjustment member 57, as in the conventional example. From the center of the upper and lower edges of the base portion 3, the connecting portion 7 is inclined downward by about 20 ° and extends downward. The holding part 5 is for holding an aromatic cleaning agent (chemical solution), extends parallel to the upper and lower edges of the base part 3, and is connected to the base part 3 via a connecting part 7. The holding part 5 is inclined at the same angle as the connecting part 7 and is connected on the same plane as the connecting part 7. Thus, although the base 3 and the holding part 5 are connected by the connecting part 7, the left and right widths of the connecting part 7 are sufficiently narrower and narrower than the left and right widths of the base part 3. A space S is ensured between 5 and 5. In addition, the inclination angle of the connecting portion 7 is not limited to the above 20 °, and can be arbitrarily selected within a range of 1 to 90 °, but is preferably set to 10 to 60 °. Moreover, the holding part 5 and the connection part 7 do not necessarily need to incline at the same angle, and at least the connection part 7 should just incline at the said angle.
[0034]
A plurality of grooves 9 are formed in the left-right direction on the upper surface of the base 3, that is, the surface facing the discharge pipe 53. This groove 9 is for the fragrance cleaning agent discharged from the discharge pipe 53 to circulate. Since the discharge pipe 53 is in contact with or close to the base 3 at a very close interval, the fragrance cleaning agent discharged from the discharge pipe 53 mainly flows into the storage chamber 57a through the groove 9. Thus, the amount of the aromatic cleaning agent discharged from the discharge pipe 53 is adjusted. In addition, among the plurality of grooves 9, the one disposed in the center extends from the base portion 3 through the connecting portion 7 to the edge of the holding portion 5. The groove 9 a constitutes a guide groove 9 a that guides the fragrance cleaning agent discharged from the discharge pipe 53 to the holding unit 5.
[0035]
In addition, although the dimension of each groove | channel 9 formed on the base 3 can be suitably adjusted with the viscosity and surface tension of an aromatic cleaning agent, the width | variety is from a viewpoint of restrict | limiting the distribution | circulation amount of an aromatic cleaning agent, Preferably it is 0.03-4 mm, More preferably, it is 0.1-2 mm. Moreover, the length from the surface of the base 3 to the deepest part of the groove | channel 9 becomes like this. Preferably it is 0.03-4 mm, More preferably, it is 0.1-2 mm. When the width and depth are larger than this range, the discharge amount of the fragrance cleaning agent becomes too large. On the other hand, when the width and depth are smaller than this range, the discharge amount becomes too small and the fragrance cleaning agent is not sufficiently supplied. Moreover, the cross-sectional shape of the groove | channel 9 can be made into various shapes, such as V-shape (a), U-shape (b), a rectangle (c), and a variant (d), as shown, for example in FIG.
[0036]
The connecting portion 7 extends toward the opening 69 (FIG. 11A) formed in the support body 59, whereby the holding portion 5 is in a state of protruding from the opening 69 to the outside of the support body 59. ing.
[0037]
Next, the operation of the chemical liquid supply tool configured as described above will be described. The fragrance cleaning agent discharged from the chemical solution container 51 through the discharge pipe 53 flows into the storage chamber 57a through the groove 9 on the base 3, and part of it flows into the guide groove 9a. Then, the fragrance cleaning agent that has flowed into the guide groove 9a reaches the holding portion 5 via the connecting portion 7, and then spreads and is held along the left and right width directions of the holding portion 5. At this time, the fragrance cleaning agent on the holding part 5 is in a state exposed to the outside of the support body 59, and has an fragrance effect.
[0038]
When running water flows during flushing, the aromatic cleaning agent on the holding unit 5 is washed away by running water and flows into a water storage tank (not shown). At this time, part of the flowing water enters the support body 59 through the opening 69 of the support body 59. And if it is a prior art example, this flowing water will flow to the base side, However, In the chemical | medical solution supply tool which concerns on this embodiment, this can be prevented.
[0039]
That is, in the chemical solution supply member 1 described above, since the space S is formed between the base 3 and the holding unit 5, the path from the holding unit 5 to the base 3 is blocked. Accordingly, the fragrance cleaning agent on the holding unit 5 is washed away, and the flowing water toward the base 3 side flows out from the space S to the lower side of the chemical solution supply member before reaching the base 3. Thereafter, the flowing water flows out from the opening 69 of the support body 59 to the outside.
[0040]
As described above, according to the present embodiment, it is possible to prevent the flowing water at the time of flushing from reaching the base 3, and therefore, it is possible to prevent the flowing water from entering the chemical liquid container 51 that has become a negative pressure due to a temperature change. it can. Therefore, it is possible to prevent a decrease in the viscosity of the fragrance cleaning agent, and it is possible to reliably prevent the fragrance cleaning agent from rapidly decreasing due to a decrease in viscosity in the later stage of use as in the conventional example.
[0041]
(Second Embodiment)
Next, 2nd Embodiment of the chemical | medical solution supply tool which concerns on this invention is described. FIG. 3 is a plan view (a) and a side view (b) of a chemical solution supply member used in the chemical solution supply tool according to the present embodiment.
[0042]
The chemical solution supply member according to this embodiment differs from that according to the first embodiment in the configuration of the connecting portion and the groove. As shown in FIG. 3, in this chemical solution supply member 11, two elongated connecting portions 15 are provided at the upper and lower edges of the base portion 13. These connecting portions 15 are inclined downward by about 20 ° as in the first embodiment. On the base portion 13, four grooves 17 are arranged so as to form an X shape, and an end portion of each groove 17 extends to a connecting portion between the base portion 13 and the connecting portion 15. These grooves 17 are configured to pass through the connecting portion 15 and extend to the end edge of the holding portion 19. Note that the left and right widths of each connecting portion 15 are narrower than those shown in the first embodiment, and can be, for example, about half. Thereby, even if the number of the connection parts 15 increases, the area in planar view of the space S formed between the base parts 13 is securable.
[0043]
As described above, according to the present embodiment, since two connecting portions 15 that connect each holding portion 19 and the base portion 13 are provided, the holding portion 19 and the base portion 13 are stably connected. . Therefore, it is possible to prevent the connecting portion 15 from being easily bent or deformed. Thereby, it can prevent that the fragrance cleaning agent hold | maintained on the holding | maintenance part 19 flows out unexpectedly by the deformation | transformation of the connection part 15, and can hold | maintain an fragrance cleaning agent stably. Further, since the portion other than the connecting portion 15 is a space between the holding portion 19 and the base portion 13, the flowing water from which the fragrance cleaning agent on the holding portion 19 is washed out is the base portion as in the first embodiment. It can prevent coming to 13 side.
[0044]
In the above example, two connecting portions 15 are provided on one side of the base portion 13, but the number of connecting portions 15 is not limited to this, and more connecting portions 15 can be provided.
[0045]
(Third embodiment)
Next, 3rd Embodiment of the chemical | medical solution supply tool which concerns on this invention is described. FIG. 4 is a plan view (a) and a side view (b) of a chemical solution supply member used in the chemical solution supply tool according to the present embodiment.
[0046]
The chemical solution supply member according to this embodiment is different from that according to the first embodiment in that an inclined portion described below is formed in the base portion.
[0047]
As shown in FIG. 4A, the chemical solution supply member 21 according to the present embodiment is formed with a rectangular inclined portion 27 along the upper and lower edges of the base portion 23, that is, the edge facing the holding portion 25. Has been. As shown in FIG. 4B, the inclined portion 27 is inclined downward at an inclination angle smaller than that of the connecting portion 29. More specifically, the connecting portion 29 is inclined at an angle of about 20 °, while the inclined portion 27 is inclined at an angle of about 10 °.
[0048]
This configuration has the following advantages. That is, a part of the flowing water for washing away the aromatic cleaning agent on the holding part 25 at the time of flushing flows toward the base 23 side. At this time, the inclined part 27 serves as a blocking wall against the flowing water. That is, as shown in FIG. 4B, since the inclined portion 27 is inclined at an angle smaller than that of the connecting portion 29 and the holding portion 25, the upward flowing water along the holding portion 25 is caused by the inclined portion 27. It is shut off and directs running water downwards.
[0049]

(Fourth embodiment)
Next, 4th Embodiment of the chemical | medical solution supply tool which concerns on this invention is described. FIG. 5 is a plan view (a) and a side view (b) of a chemical solution supply member used in the chemical solution supply tool according to the present embodiment.
[0052]
The chemical solution supply member according to this embodiment is different from that according to the first embodiment in the configuration of the base and the groove.
[0053]
As shown in FIG. 5, in the chemical liquid supply member 31 according to this embodiment, the left and right widths of the base portion 33 are substantially the same as the left and right widths of the connecting portion 35. Therefore, the chemical solution supply member 31 is not combined with the adjustment member 57 to form the storage chamber 57a, and the fragrance cleaning agent discharged from the discharge pipe 53 flows out onto the base 33 as it is. Therefore, in this embodiment, the adjusting member 57 is not provided, and only the discharge pipe 53 is used.
[0054]
In FIG. 5A, grooves 34 are formed on the base 33 over the entire width direction of the right and left, and each groove 34 is a converging groove 36 formed obliquely in the vicinity of the upper and lower edges of the base 33. It is connected to the. Then, the fragrance cleaning agent that has passed through each groove 34 and has flowed into the joining groove 36 is guided to the holding portion 37 via the guide groove 38.
[0055]
Also in this embodiment, the water S flows into the chemical liquid container 51 in order to block the flowing water that has washed away the fragrance cleaning agent in the holding part 37 from flowing into the base 33 side by the space S between the base part 33 and the holding part 37. Can be prevented, and the viscosity of the aromatic cleaning agent can be prevented from decreasing. Note that the space S between the base portion 33 and the holding portion 37 here refers to a space extending over the entire left and right width of the holding portion 37.
[0056]
As mentioned above, although embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. For example, in each of the above embodiments, each groove on the base is formed so as to extend in the vertical direction of the base. However, as shown in FIG. It can also be formed so as to be orthogonal to the direction in which the portions 7 and 15 extend.
[0057]
Moreover, in the said embodiment, although only one guide groove was formed in each connection part, as shown in FIG. 7, the several guide groove 43 can also be formed. In this case, as shown in the figure, the guide groove 43 may be formed over the entire left and right width of the connecting portion 7 or may be formed over a part of the left and right width of the connecting portion 7. It may be.
[0058]
Furthermore, in each said embodiment, although the groove | channel was formed on the base, it is not limited to this, The shape will not be specifically limited if it is a recessed part which a fragrance cleaning agent can distribute | circulate. Absent. For example, as shown in FIG. 8, the groove 9 and a hemispherical recess 45 may be combined. In this case, the end of the discharge pipe 53 is arranged so as to pass through the position of the broken line in FIG. 1, that is, a part of each recess 45, whereby the aromatic cleaning agent passes through the recess 45 and the storage chamber or the guide groove 9. It is possible to flow to the side.
[0059]
Moreover, in the said embodiment, although the discharge part of this invention is formed in the tubular shape as the discharge pipe 53, it does not necessarily need to be tubular, The shape which can supply the chemical | medical solution from the chemical | medical solution container 51 to the base of a chemical | medical solution supply member If it is.
[0060]
【Example】
Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. Here, the chemical solution supply member shown in FIG. 1 (Example 1), FIG. 3 (Example 2), and FIG. 8 (Example 3) is used as an example, and the conventional chemical solution shown in FIG. A chemical supply tool using a supply member is used. In addition, the structure of the chemical | medical solution supply tool in each Example and a comparative example is the same except the said chemical | medical solution supply member, and uses what is shown in FIG.11 and FIG.12. And when using these chemical | medical solution supply tools, (1) The quantity of the water mixed in in a chemical | medical solution container, and (2) The residual rate of an aromatic cleaning agent were measured.
[0061]
(1) Experiment 1
As described above, the amount of water mixed in the chemical container is measured. The experimental method is as follows.
{Circle around (1)} The chemical supply tool to which each of the above chemical supply members is attached is installed on the hand washing part of S731B manufactured by TOTO. The room temperature at this time was 23 ° C.
(2) Prepare 3 liters of 0.1% by weight edible blue No. 1 aqueous solution and adjust the water temperature to 13 ° C.
(3) The blue No. 1 aqueous solution prepared in (2) above is caused to flow down to the upper center of the chemical solution supply device at a flow rate of 50 ml / second.
{Circle around (4)} After 10 minutes, the aromatic cleaning agent in the bottle is collected and the absorbance is measured by UV-1600 manufactured by Shimadzu Corporation to calculate the amount of water mixed into the chemical solution container.
[0062]
As a result, the mixing amount of Examples 1 to 3 was 50 mg or less, while that of Comparative Example 1 was 220 mg. Thereby, in each Example in which a space is formed between the base portion and the holding portion, it is clear that the inflow of the fragrance cleaning agent to the base portion side is prevented, and thereby water in the chemical solution container is prevented. The amount of contamination is low.
[0063]
(2) Experiment 2
For each flush, the remaining ratio of the aromatic cleaning agent remaining in the chemical container (remaining ratio when the initial state is 100%) was measured. In this experiment, an experiment was conducted by adding a chemical solution impregnation type chemical solution supply device prepared according to Patent Document 1 as Comparative Example 2. The experimental method is as follows.
{Circle around (1)} The chemical supply tool to which each of the above chemical supply members is attached is installed on the hand washing part of S731B manufactured by TOTO.
(2) Flushing was performed at a rate of once per hour, and the residual rate was derived by measuring the weight of the chemical supply tool each time. The experiment was performed under the following two conditions with different room temperature and water temperature.
[0064]
Hereinafter, experimental results will be described. FIG. 9 is a graph showing the relationship between the number of flushes and the remaining ratio of the aromatic cleaning agent. FIG. 9A shows the result of Experiment 2-I, and FIG. 9B shows the result of Experiment 2-II.
[0065]
(2-I) Room temperature 23 ° C, water temperature 25 ° C
As shown in FIG. 9 (a), according to this experiment, since the water temperature is higher than room temperature, in Comparative Example 1, although the amount of water mixed into the chemical solution container is small, The viscosity is definitely reduced. Therefore, in the later stage of use, the amount of fragrance cleaning agent decreases, the remaining rate decreases more rapidly than in Examples 1 to 3, and the number of uses decreases. On the other hand, in Examples 1 to 3, it is clear that the inflow of water into the chemical solution container is prevented, and the decrease in the viscosity of the fragrance cleaning agent due to the mixing of water is suppressed.
[0066]
(2-II) Room temperature 15 ° C, water temperature 5 ° C
As shown in FIG. 9B, according to this experiment, in Examples 1 to 3, the decrease in the residual rate is moderate from the initial use to the middle period, but in Comparative Example 1, the decrease is further moderate. ing. This is because the room temperature is higher than the water temperature, and the chemical container is cooled at each flush and the inside of the container becomes negative pressure, so that more water flows into the chemical container than in Experiment 2-I. In the latter period of use of the comparative example, the residual rate is significantly lower than those in Examples 1 to 3. The reason for this is that water flows in early and mid-use, so the decrease in fragrance cleaner becomes very gradual, but the viscosity of the fragrance cleaner is close to that of water in the latter period of use and is discharged at once. It is.
[0067]
In Comparative Example 2, the aromatic cleaning agent discharged from the chemical solution container is absorbed by the impregnated body, and the impregnated body is in direct contact with running water to wash away the aromatic cleaning agent. Therefore, the aromatic cleaning agent absorbed in the impregnated body is diluted with running water. Thus, in Comparative Example 2, the aromatic cleaning agent is easily discharged from the chemical solution container to supplement the diluted aromatic cleaning agent, and the decrease in the chemical solution is significantly faster than the other examples through the above experiments.
[0068]
The remaining ratio of the fragrance cleaning agent at the end of use was examined in more detail. Table 1 below shows changes in the slope of each graph in FIG. 9B.
[0069]
[Table 1]

[0070]
* Unit: Weight loss ratio per flash (%) =-(Yn-Ym) / (nm)
m, n: number of flashes (where m <n)
Ym: Residual rate at m times (%)
Yn: Residual rate at n times (%)
According to Table 1 above, it is clear that the amount of decrease in the fragrance cleaning agent in Comparative Examples 1 and 2 is large in the later stage of use. From the above, in Examples 1 to 3, it is clear that the space between the base portion and the holding portion prevents water from flowing into the chemical solution container and prevents a decrease in the viscosity of the fragrance cleaning agent. is there. Therefore, in the present Example, it turned out that a fragrance cleaning agent is prevented from decreasing rapidly in the latter period of use compared with a comparative example.
[0071]
