The communication holes 61 are used for the chemical liquid discharged from the chemical liquid container 2 to the connecting portion 43A. The portion can be introduced into the buffer chamber 60. In addition, an air circulation hole 62 that allows the buffer chamber 60 to communicate with the outside is formed in the upper surface portion 40A (upper step portion 40b).

薬液供給部材５は、例えばプラスチックで形成され、支持体３の底面部３０Ａ上に載置される。この薬液供給部材５は、排出管４３Ｂの下端部に対向配置され、排出管４３Ｂの下端部が当接または近接する基部５０と、基部５０の両側縁（図１１（ａ）の上下辺）から下方へ傾斜する一対の保持部５１とを備えている。基部５０において排出管４３Ｂが当接または近接する部分およびその近傍には、薬液が流通可能な複数の溝５２が幅方向（図１１（ａ）の左右方向）に形成されている。複数の溝５２は、基部５０の一方の側縁から他方の側縁まで延び、これらの溝５２のうち、中央に配置されたものは保持部５１の端部まで延びる案内溝５３を構成している。この案内溝５３は、薬液を基部５０から保持部５１の端部まで導くようになっている。各保持部５１の端部は、支持体３の開口３３から突出している。 The chemical solution supply member 5 is formed of plastic, for example, and is placed on the bottom surface 30 A of the support 3.

A buffer chamber 60 having a space capable of storing a chemical solution surrounded by the side surface portion 40B (side wall) and the upper surface portion 40A (upper wall) of the adjustment member 4 is formed. The buffer chamber 60 constitutes a buffer mechanism 6 that adjusts the amount of the chemical liquid discharged from the chemical liquid container 2, and the buffer mechanism 6 includes the buffer chamber 60, the communication hole 61 and the air circulation hole 62 described above. The

上記構成の薬液供給装置１０は、次のように動作する。すなわち、薬液容器２内の薬液は接続部４３Ａから排出管４３Ｂに流入して薬液供給部材５の基部５０から保持部５１上に排出されるとともに、その一部が連通孔６１を介して緩衝室６０に貯留される。各保持部５１上の薬液は、保持部５１の左右の幅方向に沿って広がり、フラッシュ時に給水受皿１００に供給される流水が、開口３３から支持体３内に流れ込んで各保持部５１上の薬液を洗い流すことで、排水口１０１から貯水タンクに流れ込む。 The chemical solution supply apparatus 10 having the above configuration operates as follows. That is, the chemical solution in the chemical solution container 2 flows into the discharge pipe 43B from the connection portion 43A and is discharged onto the holding portion 51 from the base portion 50 of the chemical solution supply member 5, and a part of the chemical solution is buffered through the communication hole 61. 60 is stored. The chemical solution on each holding part 51 spreads along the left and right width directions of the holding part 51, and the flowing water supplied to the water supply tray 100 at the time of flushing flows into the support 3 from the opening 33 and is on each holding part 51. By washing away the chemical solution, it flows from the drain port 101 to the water storage tank.

このとき、温度変化によって薬液容器２内に圧力変化が生じた場合には、緩衝機構６が次のように作用する。例えば、薬液容器２内の温度が周囲温度より高くなると、薬液容器２内の空気が膨張して薬液容器２内は正圧になる。この場合、薬液容器２内の薬液は押し出されて排出口２０から排出されるが、排出された薬液は、排出管４３Ｂから薬液供給部材５へ流れ込むほか、連通孔６１を介して緩衝室６０にも流れ込むため、薬液が薬液供給部材５へ過剰に流出するのが防止される。 At this time, when a pressure change occurs in the chemical liquid container 2 due to a temperature change, the buffer mechanism 6 acts as follows. For example, when the temperature in the chemical liquid container 2 becomes higher than the ambient temperature, the air in the chemical liquid container 2 expands and the pressure in the chemical liquid container 2 becomes positive. In this case, the chemical solution in the chemical solution container 2 is pushed out and discharged from the discharge port 20, but the discharged chemical solution flows into the chemical solution supply member 5 from the discharge pipe 43 B and enters the buffer chamber 60 through the communication hole 61. Therefore, the chemical liquid is prevented from excessively flowing out to the chemical liquid supply member 5.

一方、フラッシュ時の流水で冷やされるなどして、薬液容器２内の温度が周囲温度よりも低下すると、薬液容器２内の空気が収縮して薬液容器２内は負圧になる。この場合には、薬液供給部材５の各保持部５１上に存在する薬液やフラッシュ時の水が各溝５２を通じて排出管４３Ｂから吸引されて薬液容器２に逆流する現象（以下、「水置換現象」という。）が起こるおそれがあるが、空気流通孔６２の作用により大気圧または室内圧となっている緩衝室６０内の薬液が、連通孔６１を介して薬液容器２内へ優先的に吸引されるので、水置換現象が起こるのが抑えられる。その結果、薬液容器２内の薬液が使用に伴い極度に希釈されるのが防止される。また、フラッシュ毎に、多少は水置換現象が起こるため、薬液容器２内の薬液の減少を緩やかなものにできる。このように、緩衝機構６によって、温度変化によって薬液容器２内に圧力変化が生じた場合でも、薬液容器２と緩衝室６０との間での薬液の流通が生じるため、薬液容器２内の薬液が過剰に流出したり薬液が過度に希釈されるのが防止されている。 On the other hand, when the temperature in the chemical liquid container 2 falls below the ambient temperature due to cooling with running water at the time of flushing, the air in the chemical liquid container 2 contracts and the inside of the chemical liquid container 2 becomes negative pressure. In this case, a chemical solution existing on each holding portion 51 of the chemical solution supply member 5 or water at the time of flushing is sucked from the discharge pipe 43B through each groove 52 and flows back to the chemical solution container 2 (hereinafter referred to as “water replacement phenomenon”). The chemical solution in the buffer chamber 60, which is at atmospheric pressure or the indoor pressure due to the action of the air circulation hole 62, is preferentially sucked into the chemical solution container 2 through the communication hole 61. As a result, the occurrence of the water replacement phenomenon is suppressed. As a result, the chemical solution in the chemical solution container 2 is prevented from being extremely diluted with use. In addition, since the water replacement phenomenon occurs somewhat with each flush, the decrease in the chemical solution in the chemical solution container 2 can be moderated. In this way, even when a pressure change occurs in the chemical solution container 2 due to a temperature change by the buffer mechanism 6, the chemical solution flows between the chemical solution container 2 and the buffer chamber 60. Is prevented from excessively flowing out or excessively diluting the chemical solution.

上記構成の薬液供給装置１０では、次のような問題があった。すなわち、室温が水温よりも高い場合には、フラッシュ時に供給される流水により薬液容器２は冷やされて薬液容器２内が負圧になる。そのため、薬液容器２内には緩衝室６０の薬液のみならず、各保持部５１上の水や薬液が排出管４３Ｂから多少は吸い込まれて混ざり合い、そして、フラッシュ後、水によって冷やされた薬液容器２は、徐々に室温まで暖められる結果、薬液容器２内が正圧になって、薬液が排出される。 The chemical solution supply apparatus 10 having the above configuration has the following problems. That is, when the room temperature is higher than the water temperature, the chemical liquid container 2 is cooled by the flowing water supplied at the time of flushing, and the inside of the chemical liquid container 2 becomes negative pressure. Therefore, not only the chemical solution in the buffer chamber 60 but also the water and the chemical solution on each holding part 51 are slightly sucked and mixed in the chemical solution container 2 from the discharge pipe 43B, and the chemical solution cooled by water after flushing. As a result of gradually warming the container 2 to room temperature, the inside of the chemical liquid container 2 becomes a positive pressure, and the chemical liquid is discharged.

一方で、室温が水温よりも低い場合には、フラッシュ時に供給される流水が薬液容器２を暖めるため、薬液容器２内が正圧になり、薬液容器２内の薬液の流出が促進される。しかし、フラッシュ後には、水によって暖められた薬液容器２が室温によって徐々に冷やされ、薬液容器２内が負圧になるが、このとき、フラッシュ時の水は既に流されて排水口１０１から貯水タンクに流れ込んでいるため、各保持部５１上には水や薬液がほとんど残存していない。よって、水置換現象が起こらず、薬液容器２内の薬液の減りが早くなるという問題がある。また、これは、薬液容器２内からの薬液の排出が進み、薬液容器２内に占める空気の体積が増加する使用後期に顕著となる。すなわち、使用初期は、薬液容器２内の空気の体積が小さいため、温度変化による空気の膨張量が小さく、これによる薬液の排出量は大きくない。しかし、使用後期には、薬液容器２内の空気の体積が大きくなるため、温度変化による空気の膨張量も大きく、これによって薬液容器２内の空気が薬液を押し出す圧力も大きくなる。よって、使用後期には薬液の排出量が大きくなることにより、薬液供給装置１０の使用可能回数が減少するという問題がある。 On the other hand, when the room temperature is lower than the water temperature, the flowing water supplied at the time of flushing warms the chemical liquid container 2, so that the chemical liquid container 2 has a positive pressure and the outflow of the chemical liquid in the chemical liquid container 2 is promoted. However, after flushing, the chemical solution container 2 warmed by water is gradually cooled at room temperature, and the inside of the chemical solution container 2 becomes negative pressure. At this time, the water at the time of flushing has already flowed and stored from the drain port 101. Since it flows into the tank, almost no water or chemicals remain on each holding part 51. Therefore, there is a problem that the water replacement phenomenon does not occur and the decrease of the chemical solution in the chemical solution container 2 is accelerated. In addition, this becomes conspicuous in the later stage of use in which the discharge of the chemical solution from the chemical solution container 2 proceeds and the volume of air in the chemical solution container 2 increases. That is, since the volume of the air in the chemical solution container 2 is small at the initial stage of use, the amount of expansion of the air due to temperature change is small, and the discharge amount of the chemical solution due to this is not large. However, in the later stage of use, the volume of air in the chemical liquid container 2 increases, so that the amount of expansion of the air due to temperature change is large, thereby increasing the pressure with which the air in the chemical liquid container 2 pushes out the chemical liquid. Therefore, there is a problem that the number of times that the chemical solution supply apparatus 10 can be used decreases due to an increase in the discharge amount of the chemical solution in the later stage of use.

このような問題は、貯水タンク上部の給水受皿に設置されるタイプのみならず、便器のリムに取り付けられるタイプの薬液供給装置においても起こりうる問題である。 Such a problem is a problem that may occur not only in the type installed in the water supply tray at the upper part of the water storage tank but also in the chemical solution supply apparatus of the type attached to the rim of the toilet bowl.

以下、本発明の実態形態について添付図面を参照して説明する。本発明に係る薬液供給装置１が、従来例の薬液供給装置１０（図８〜図１１に示す）と大きく相違する点は、薬液供給部材の構成であり、その他の構成は従来例の薬液供給装置１０とほぼ同様である。そのため、以下の説明では、薬液供給部材を中心に説明し、本発明に係る薬液供給装置１と従来例の薬液供給装置１０との同一構成には同一符号を付してその説明を省略する。なお、以下の説明では、水洗トイレの貯水タンク上部に設けられる手洗用の給水受皿に設置されるタイプの薬液供給装置を例に挙げている。 Hereinafter, actual forms of the present invention will be described with reference to the accompanying drawings. The chemical liquid supply apparatus 1 according to the present invention is greatly different from the conventional chemical liquid supply apparatus 10 (shown in FIGS. 8 to 11) in the configuration of the chemical liquid supply member, and other configurations are the conventional chemical liquid supply. It is almost the same as the apparatus 10. Therefore, in the following description, it demonstrates centering on a chemical | medical solution supply member, the same code | symbol is attached | subjected to the same structure of the chemical | medical solution supply apparatus 1 which concerns on this invention, and the chemical | medical solution supply apparatus 10 of a prior art example, and the description is abbreviate | omitted. In the following description, a chemical solution supply device of a type installed in a water-washing tray for hand-washing provided at the upper part of a water storage tank of a flush toilet is taken as an example.

（第１実施形態）
本発明の第１実施形態について、図１および図２を参照しつつ説明する。第１実施形態では、図１および図２に示すように、薬液供給装置１の薬液供給部材５’は、例えばプラスチックなどで板状に形成されたものであり、対向配置される排出管４３Ｂ（排出部材４２）の下端部が当接または近接する基部５０と、基部５０の両側縁（図１（ａ）の上下辺）から下方へ傾斜する一対の保持部５１とを備えている。 (First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. 1 and 2. In the first embodiment, as shown in FIGS. 1 and 2, the chemical liquid supply member 5 ′ of the chemical liquid supply apparatus 1 is formed in a plate shape with plastic or the like, for example, and is disposed opposite to the discharge pipe 43 B ( The base 50 which the lower end part of the discharge | emission member 42 contact | abuts or adjoins, and a pair of holding part 51 which inclines below from the both-sides edge (upper and lower sides of Fig.1 (a)) of the base 50 are provided.

基部５０は、矩形状に形成され、従来例の薬液供給装置１０と同様に、調整部材４が上から被せられた状態で支持体３の底面部３０Ａ上に装着される。これにより、基部５０と、調整部材４の側面部４０Ｂと、調整部材４の上面部４０Ａとで緩衝室６０が形成される。排出管４３Ｂ（排出部材４２）と対向する基部５０の上面には、排出管４３Ｂ（排出部材４２）の下端部が当接または近接する部分およびその近傍に、複数の溝５２が幅方向（図１（ａ）の左右方向）に形成されている。複数の溝５２は、基部５０の一方の側縁から他方の側縁まで延び、また、左右方向の幅Ｄも排出管４３Ｂの径より大きく設定されていて、排出管４３Ｂ（排出部材４２）の下端部が当接または近接する部分を十分にカバーするように設けられている。 The base 50 is formed in a rectangular shape, and is mounted on the bottom surface 30 A of the support 3 with the adjustment member 4 covered from above, as in the case of the conventional chemical solution supply apparatus 10. As a result, the buffer chamber 60 is formed by the base portion 50, the side surface portion 40 B of the adjustment member 4, and the upper surface portion 40 A of the adjustment member 4. On the upper surface of the base 50 facing the discharge pipe 43B (discharge member 42), a plurality of grooves 52 are formed in the width direction (see FIG. 1 (a) in the left-right direction). The plurality of grooves 52 extend from one side edge of the base 50 to the other side edge, and the width D in the left-right direction is set to be larger than the diameter of the discharge pipe 43B, so that the discharge pipe 43B (discharge member 42) The lower end portion is provided so as to sufficiently cover the portion that comes into contact with or is close to.

各溝５２は、排出管４３Ｂから排出される薬液を流通させるためのものである。排出管４３Ｂは、基部５０に当接または非常に近い間隔で近接しているため、排出管４３Ｂから排出された薬液は、各溝５２を介して各保持部５１まで案内されるか、各溝５２を介して緩衝室６０に流れ込む。複数の溝５２のうち、その中央に配置されているものは各保持部５１の端部まで延びて案内溝５３を構成しており、この案内溝５３は、排出管４３Ｂから排出された薬液を各保持部５１の端部まで案内する。なお、溝５２，５３の形状は、断面視Ｖ字状、Ｕ字状、矩形状など、種々の形状にすることかできる。 Each groove | channel 52 is for distribute | circulating the chemical | medical solution discharged | emitted from the discharge pipe 43B. Since the discharge pipe 43B is in contact with or close to the base 50 at a very close interval, the chemical liquid discharged from the discharge pipe 43B is guided to each holding part 51 through each groove 52 or each groove. It flows into the buffer chamber 60 through 52. Among the plurality of grooves 52, the one disposed at the center thereof extends to the end of each holding part 51 to form a guide groove 53, which guides the chemical solution discharged from the discharge pipe 43 B. Guide to the end of each holding part 51. The grooves 52 and 53 can have various shapes such as a V shape, a U shape, and a rectangular shape in cross section.

各保持部５１は、薬液容器２から排出された薬液を保持するためのものであり、各保持部５１の端部は支持体３の開口３３から突出し、保持部５１上の薬液がフラッシュ時に給水受皿１００に供給される流水に洗い流される。また、保持部５１上の薬液は芳香効果も奏するようになっている。なお、各保持部５１は、必ずしも基部５０に対して傾斜している必要はなく、基部５０と同一平面となるように接続されていてもよい。 Each holding part 51 is for holding the chemical liquid discharged from the chemical liquid container 2, and an end of each holding part 51 protrudes from the opening 33 of the support 3, and the chemical liquid on the holding part 51 is supplied with water during flushing. It is washed away with running water supplied to the tray 100. Moreover, the chemical | medical solution on the holding | maintenance part 51 also has an aroma effect. Each holding portion 51 does not necessarily have to be inclined with respect to the base portion 50, and may be connected so as to be flush with the base portion 50.

薬液供給部材５’はまた、水や薬液を貯留可能な貯留部７を備えている。第１実施形態では、排出管４３Ｂ（排出部材４２）と対向する基部５０上に、排出管４３Ｂ（排出部材４２）の下端部を取り囲むようにして筒状体７０が設けられている。筒状体７０の上端面は開放されており、その内部空間が水や薬液を貯留可能な貯留部７を構成している。 The chemical liquid supply member 5 ′ is also provided with a storage portion 7 that can store water and chemical liquid. In the first embodiment, the cylindrical body 70 is provided on the base 50 facing the discharge pipe 43B (discharge member 42) so as to surround the lower end of the discharge pipe 43B (discharge member 42). The upper end surface of the cylindrical body 70 is open, and its internal space constitutes a storage portion 7 capable of storing water and chemicals.

排出管４３Ｂ（排出部材４２）の下端部は、貯留部７内に配置されていて、貯留部７内の水や薬液は、基部５０上面の各溝５２を介して排出管４３Ｂ（排出部材４２）の下端部から排出管４３Ｂ（排出部材４２）内に流入可能である。このように、貯留部７は、排出管４３Ｂ（排出部材４２）の下端部との間で、水または薬液を流通可能なように設けられている。 The lower end of the discharge pipe 43B (discharge member 42) is disposed in the storage section 7, and water and chemicals in the storage section 7 are discharged from the discharge pipe 43B (discharge member 42) via the grooves 52 on the upper surface of the base 50. ) Can flow into the discharge pipe 43B (discharge member 42). Thus, the storage part 7 is provided so that water or a chemical | medical solution can be circulated between the lower end parts of the discharge pipe 43B (discharge member 42).

また、筒状体７０は、基部５０上面の複数の溝５２上に設けられている。これにより、フラッシュ時に給水受皿１００に供給される流水が、開口３３より支持体３内に流入して各保持部５１上の薬液を洗い流す際に、その一部が薬液とともに、各溝５２を介して調整部材４内へと流れ込み、各溝５２を伝って筒状体７０内に入り込むことで貯留部７に水や薬液が貯留される。貯留部７に貯留された水や薬液は、後述するように、薬液容器２内が負圧になったとき、排出管４３Ｂの下端部から吸引されて（水置換現象）、薬液容器２内に逆流可能になっている。 The cylindrical body 70 is provided on the plurality of grooves 52 on the upper surface of the base 50. Thereby, when the flowing water supplied to the water supply tray 100 at the time of flushing flows into the support 3 from the opening 33 to wash away the chemical solution on each holding portion 51, a part of the flowing solution passes through each groove 52 together with the chemical solution. Then, it flows into the adjusting member 4 and enters the cylindrical body 70 through each groove 52, so that water or a chemical solution is stored in the storage portion 7. As will be described later, the water or chemical stored in the storage unit 7 is sucked from the lower end of the discharge pipe 43B (water replacement phenomenon) and enters the chemical container 2 when the pressure in the chemical container 2 becomes negative. Backflow is possible.

筒状体７０の形状としては、特に限定されるものではなく、図示例のような平面視円状のほか、楕円状や多角形状など、種々の形状とすることができる。また、筒状体７０の大きさとしては、特に限定されるものではないが、図１（ａ）の左右方向における幅ｄ１が複数の溝５２の幅Ｄよりも大きく、筒状体７０が複数の溝５２の一方の端から他方の端まで跨るように設けられるのが好ましい。これにより、各溝５２を伝って調整部材４内へと流れ込む水や薬液が筒状体７０内（貯留部７）に貯め込まれやすくなる。また、筒状体７０（貯留部７）の内容積としては、特に限定されるものではないが、１回のフラッシュにより、水置換現象を起こす水や薬液の量が０．１ｍｌ〜３．０ｍｌ、好ましくは０．２ｍｌ〜２．６ｍｌ、さらに好ましくは０．２ｍｌ〜１．０ｍｌ程度となるように、筒状体７（貯留部７）の内容積が設定されていることが好ましい。水置換現象を起こす水や薬液の量が０．１ｍｌよりも小さいと、水置換現象を起こす水や薬液の量が少なく、薬液容器２内の薬液の減少を抑える効果が弱くなるおそれがある一方で、水置換現象を起こす水や薬液の量が３．０ｍｌよりも大きいと、水置換現象を起こす水や薬液の量が多くなり過ぎて、薬液容器２内の薬液を極度に希釈するおそれがあるからである。 The shape of the cylindrical body 70 is not particularly limited, and may be various shapes such as an elliptical shape and a polygonal shape in addition to a circular shape in plan view as in the illustrated example. Further, the size of the cylindrical body 70 is not particularly limited, but the width d1 in the left-right direction in FIG. 1A is larger than the width D of the plurality of grooves 52, and a plurality of cylindrical bodies 70 are provided. The groove 52 is preferably provided so as to straddle from one end to the other end. Thereby, the water and the chemical solution that flow into the adjustment member 4 through each groove 52 are easily stored in the cylindrical body 70 (storage part 7). In addition, the internal volume of the cylindrical body 70 (reservoir 7) is not particularly limited, but the amount of water or chemical that causes a water replacement phenomenon by one flush is 0.1 ml to 3.0 ml. The inner volume of the cylindrical body 7 (reservoir 7) is preferably set so that it is preferably about 0.2 ml to 2.6 ml, more preferably about 0.2 ml to 1.0 ml. If the amount of water or chemical solution causing the water replacement phenomenon is less than 0.1 ml, the amount of water or chemical solution causing the water replacement phenomenon is small, and the effect of suppressing the reduction of the chemical solution in the chemical solution container 2 may be weakened. If the amount of water or chemical solution causing the water replacement phenomenon is larger than 3.0 ml, the amount of water or chemical solution causing the water replacement phenomenon may increase so much that the chemical solution in the chemical solution container 2 may be extremely diluted. Because there is.

また、各溝５２の寸法（幅や深さ）は、適宜設定することができるが、貯留部７内に貯留された水や薬液の貯留部７内における滞在時間を制御するという観点から、上記滞在時間が１分〜３０分、好ましくは５分〜２０分程度となるように、各溝５２の寸法（幅や深さ）が設定されていることが好ましい。後述するように、室温が水温よりも低い場合には、薬液容器２内が正圧になった後、負圧になることで、貯留部７内の水や薬液が薬液容器２内に吸引される水置換現象が起こるが、この薬液容器２内が正圧になってから負圧になるまでの時間が一般的に１分〜３０分であるため、上記滞在時間が１分より小さいと、水や薬液の各溝５２による流出量が大きくなり過ぎて、水置換現象を起こす前に水や薬液が貯留部７から流れ出てしまうおそれがある一方で、上記滞在時間が３０分より大きいと、薬液に水が必要以上に混ざり合って、水置換現象を起こす液が希釈され過ぎてしまうおそれがあるからである。 Moreover, although the dimension (width | variety and depth) of each groove | channel 52 can be set suitably, from a viewpoint of controlling the residence time in the storage part 7 of the water stored in the storage part 7, or the chemical | medical solution, the said It is preferable that the dimensions (width and depth) of each groove 52 are set so that the staying time is about 1 minute to 30 minutes, preferably about 5 minutes to 20 minutes. As will be described later, when the room temperature is lower than the water temperature, the inside of the chemical liquid container 2 becomes a positive pressure and then becomes a negative pressure, whereby the water and the chemical liquid in the storage unit 7 are sucked into the chemical liquid container 2. The water replacement phenomenon occurs, but since the time from the positive pressure inside the chemical container 2 to the negative pressure is generally 1 minute to 30 minutes, While the outflow amount of each groove 52 of water or chemical liquid becomes too large and water or chemical liquid may flow out of the storage part 7 before causing the water replacement phenomenon, if the stay time is longer than 30 minutes, This is because there is a possibility that water that mixes more than necessary with the chemical liquid and that the liquid that causes the water replacement phenomenon is excessively diluted.

次に、上記構成の薬液供給装置１の動作について説明する。薬液容器２から排出される薬液は、排出管４３Ｂを経て薬液供給部材５’上に排出されるとともに、連通孔６１を経て緩衝室６０内に流れ込む。薬液供給部材５’上に排出された薬液は、基部５０上面の各溝５２を介して各保持部５１に流れ込み、保持部５１の左右の幅方向に沿って広がって保持される。そして、フラッシュ時に給水受皿１００に供給される流水が、開口３３から支持体３内に流れ込んで各保持部５１上の薬液を洗い流すことで、排水口１０１から貯水タンクに流れ込む。 Next, the operation of the chemical solution supply apparatus 1 configured as described above will be described. The chemical liquid discharged from the chemical liquid container 2 is discharged onto the chemical liquid supply member 5 ′ through the discharge pipe 43 B and flows into the buffer chamber 60 through the communication hole 61. The chemical solution discharged onto the chemical solution supply member 5 ′ flows into each holding portion 51 via each groove 52 on the upper surface of the base 50, and is spread and held along the left and right width directions of the holding portion 51. And the flowing water supplied to the water supply tray 100 at the time of flushing flows into the support body 3 from the opening 33 to wash away the chemical solution on each holding part 51, and then flows into the water storage tank from the drain outlet 101.

ここで、室温が水温よりも高い場合には、従来例の薬液供給装置１０と同様に、フラッシュの度に水置換現象が起こることにより、薬液容器２内の薬液の減少を緩やかなものにできる。また、水置換現象が起こる水や薬液の量が多くないため、薬液容器２内の薬液がフラッシュの度に極度に希釈されるのを防止できる。 Here, when the room temperature is higher than the water temperature, the decrease in the chemical solution in the chemical solution container 2 can be moderated by causing a water replacement phenomenon at each flush, as in the conventional chemical solution supply apparatus 10. . In addition, since the amount of water or chemical solution in which the water replacement phenomenon occurs is not large, it is possible to prevent the chemical solution in the chemical solution container 2 from being extremely diluted every time it is flushed.

一方で、室温が水温よりも低い場合には、フラッシュ時に供給される流水が薬液容器２を暖めるため、薬液容器２内が正圧になり、薬液容器２内の薬液の流出が促進される。そして、フラッシュ後には、水によって暖められた薬液容器２が室温によって徐々に冷やされ、薬液容器２内が負圧になるが、このとき、フラッシュ時に給水受皿１００の供給された流水が、開口３３より支持体３内に流入して各保持部５１上の薬液を洗い流す際に、その一部が薬液とともに、各溝５２を介して調整部材４内へと流れ込み、各溝５２を伝って筒状体７０内に流れ込むことで貯留部７に貯留されている。よって、フラッシュ後の薬液容器２内の負圧時には、貯留部７内の水や薬液が排出管４３Ｂの下端部から吸引されて薬液容器２内に逆流するため、水置換現象が起こる。 On the other hand, when the room temperature is lower than the water temperature, the flowing water supplied at the time of flushing warms the chemical liquid container 2, so that the chemical liquid container 2 has a positive pressure and the outflow of the chemical liquid in the chemical liquid container 2 is promoted. After flushing, the chemical solution container 2 heated by water is gradually cooled at room temperature, and the inside of the chemical solution container 2 becomes negative pressure. At this time, the running water supplied to the water supply tray 100 at the time of flushing is opened to the opening 33. When the chemical solution on each holding part 51 flows into the support body 3 and is washed away, a part of the chemical solution flows into the adjustment member 4 through the grooves 52 together with the chemical solution, and passes through the grooves 52 to form a cylindrical shape. By flowing into the body 70, it is stored in the storage unit 7. Therefore, at the time of negative pressure in the chemical liquid container 2 after flushing, water or chemical liquid in the storage section 7 is sucked from the lower end portion of the discharge pipe 43B and flows back into the chemical liquid container 2, so that a water replacement phenomenon occurs.

このように、従来例の薬液供給部材５では、室温が水温よりも低い場合に、フラッシュ後に薬液容器２内が負圧になった際に、フラッシュ時の水や薬液が既に洗い流されて各保持部５１上に残存していないため、フラッシュ時の水や薬液が排出管４３Ｂから吸引されて薬液容器２内に逆流する水置換現象が起こらなかったが、第１実施形態の薬液供給部材５’では、フラッシュ時の水や薬液が貯留部７に貯留されて排出管４３Ｂの周辺に残存している。そのため、フラッシュ後に、各保持部５１上に水や薬液が残存していなくても、水置換現象を確実に起こすことができる結果、室温が水温よりも低い場合においても、薬液容器２内の薬液の減少を緩やかなものとすることができる。よって、第１実施形態の薬液供給装置１では、薬液を長期間安定して供給することが可能である。また、水置換現象により薬液容器２内に吸引される水や薬液の量を調整することにより、薬液容器２内の薬液がフラッシュの度に極度に希釈されるのを防止することができる。 As described above, in the chemical solution supply member 5 of the conventional example, when the inside of the chemical solution container 2 becomes negative pressure after flushing when the room temperature is lower than the water temperature, the water and the chemical solution at the time of flushing are already washed out and retained. Since the water or chemical liquid at the time of flushing is sucked from the discharge pipe 43B and does not flow back into the chemical liquid container 2 because it does not remain on the part 51, the chemical liquid supply member 5 ′ of the first embodiment does not occur. Then, the water and chemical | medical solution at the time of flash | flush are stored in the storage part 7, and remain | survived around the discharge pipe 43B. Therefore, even if water or chemical solution does not remain on each holding part 51 after flushing, the water replacement phenomenon can be reliably caused. As a result, even when the room temperature is lower than the water temperature, the chemical solution in the chemical solution container 2 is used. Can be moderated. Therefore, in the chemical solution supply apparatus 1 of the first embodiment, it is possible to supply the chemical solution stably for a long period of time. Further, by adjusting the amount of water or chemical liquid sucked into the chemical liquid container 2 due to the water replacement phenomenon, it is possible to prevent the chemical liquid in the chemical liquid container 2 from being extremely diluted every time it is flushed.

以上、本発明の第１実施形態について詳述したが、第１実施形態の具体的な態様は上記態様に限定されない。例えば、本実施形態では、貯留部７に水または薬液を導出入可能な通水手段として、薬液供給部材５’に形成された複数の溝５２が用いられているが、まず、薬液供給部材５’に溝５２が１つだけ形成され、この１つの溝５２だけが通水手段として用いられる構成であってもよい。また、本実施形態では、複数の溝５２の全てに跨るように筒状体７０が設けられていて、複数の溝５２の全てが通水手段として用いられているが、複数の溝５２の一部だけが筒状体７０内に存在して通水手段として用いられ、残部（例えば一端側または両端側の溝５２）は筒状体７０外に存在して、単に基部５０上の薬液を各保持部５１まで流通させる機能だけを果たすように構成されていてもよい。また、本実施形態では、基部５０の両端に亘って延びる溝５２が、貯留部７および排出管４３Ｂ（排出部材４２）の下端部を流通可能にする流通機能を果たすとともに、貯留部７に水または薬液を導出入可能にする通水機能（通水手段）を果たしているが、上記流通機能と上記通水機能（通水手段）とを、それぞれ異なる溝により実現するように構成してもよい。また、この場合、通水手段を溝ではなく、筒状体７０の周面に形成した、水や薬液を導出入可能な切り欠き、孔などで構成することもできる。また、通水手段は、必ず必要というわけではなく、筒状体７０の高さに応じて水や薬液が筒状体７０を乗り越えて貯留部７内に浸入可能である場合には、通水手段を備えていなくてもよい。 As mentioned above, although 1st Embodiment of this invention was explained in full detail, the specific aspect of 1st Embodiment is not limited to the said aspect. For example, in the present embodiment, a plurality of grooves 52 formed in the chemical liquid supply member 5 ′ are used as water passing means capable of introducing or introducing water or chemical liquid into the reservoir 7, but first, the chemical liquid supply member 5 is used. A configuration may be adopted in which only one groove 52 is formed in 'and only this one groove 52 is used as a water flow means. In the present embodiment, the cylindrical body 70 is provided so as to straddle all of the plurality of grooves 52, and all of the plurality of grooves 52 are used as the water passage means. Only the portion exists in the cylindrical body 70 and is used as water passing means, and the remaining portion (for example, the groove 52 on one end side or both end sides) exists outside the cylindrical body 70, and the chemical solution on the base 50 is simply passed through each portion. You may be comprised so that only the function to distribute | circulate to the holding | maintenance part 51 may be fulfilled. Moreover, in this embodiment, the groove | channel 52 extended over the both ends of the base 50 fulfill | performs the distribution | circulation function which can distribute | circulate the storage part 7 and the lower end part of the discharge pipe 43B (discharge member 42), and water is added to the storage part 7. Alternatively, the water flow function (water flow means) that allows the chemical solution to be led out / in is fulfilled, but the flow function and the water flow function (water flow means) may be realized by different grooves. . Further, in this case, the water passing means may be constituted by notches, holes or the like formed not on the grooves but on the peripheral surface of the cylindrical body 70 and capable of introducing water and chemicals. Further, the water passing means is not necessarily required. When water or a chemical solution can get over the cylindrical body 70 and enter the storage portion 7 according to the height of the cylindrical body 70, the water passing means is used. Means may not be provided.

（第２実施形態）
次に、本発明の第２実施形態について、図３および図４を参照しつつ説明する。第２実施形態の薬液供給部材５”が、第１実施形態の薬液供給部材５’と相違するのは、貯留部７の構成である。 (Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. The chemical solution supply member 5 ″ of the second embodiment is different from the chemical solution supply member 5 ′ of the first embodiment in the configuration of the storage unit 7.

図３および図４に示すように、第２実施形態の薬液供給部材５”では、表面に表面より凹んだ凹部７１を備えており、この凹部７１内の空間が水や薬液を貯留可能な貯留部７を構成している。凹部７１は、排出管４３Ｂ（排出部材４２）の下端部が当接または近接する部分の周辺に設けられ、本実施形態では、各保持部５１の、基部５０との境目に１つずつ設けられている。また、凹部７１は、各保持部５１の基部５０との境目において、複数の溝５２が設けられている位置に対応して設けられており、複数の溝５２が凹部７１まで延びて凹部７１に接続され、凹部７１および排出管４３Ｂ（排出部材４２）の下端部との間で水または薬液を流通可能にしている。これにより、凹部７１（貯留部７）内に貯留された水や薬液は、各溝５２を介して排出管４３Ｂ（排出部材４２）の下端部から吸引されて排出管４３Ｂ（排出部材４２）内に流入可能であり、後述するように、薬液容器２内が負圧になったとき、水や薬液が排出管４３Ｂを介して薬液容器２内に逆流する水置換現象が起こるようになっている。 As shown in FIGS. 3 and 4, the chemical liquid supply member 5 ″ of the second embodiment has a concave portion 71 that is recessed from the surface on the surface, and the space in the concave portion 71 can store water and chemical liquid. The recessed part 71 is provided in the circumference | surroundings of the part which the lower end part of the discharge pipe 43B (discharge member 42) contact | abuts or adjoins, and, in this embodiment, the base 50 of each holding | maintenance part 51 is comprised. In addition, the recess 71 is provided corresponding to the position where the plurality of grooves 52 are provided at the boundary with the base 50 of each holding part 51, The groove 52 extends to the recess 71 and is connected to the recess 71, thereby allowing water or chemicals to flow between the recess 71 and the lower end of the discharge pipe 43B (discharge member 42). 7) The water and chemical solution stored in the Can be sucked from the lower end of the discharge pipe 43B (discharge member 42) and can flow into the discharge pipe 43B (discharge member 42). As described later, A water replacement phenomenon in which the chemical liquid flows back into the chemical liquid container 2 through the discharge pipe 43B occurs.

本実施形態では、凹部７１の基部５０側の面が凹部７１に向けて低く傾斜する傾斜面７２に形成されており、複数の溝５２は傾斜面７２を凹部７１の底まで延びるように形成されている。これにより、凹部７１内の水や薬液が、各溝５２を介して排出管４３Ｂ（排出部材４２）の下端部へと導かれやすくなっている。なお、凹部７１の基部５０側の面は、必ずしも傾斜面７２に形成されている必要はなく、鉛直面であっても構わない。 In the present embodiment, the surface of the recess 71 on the base 50 side is formed on an inclined surface 72 that is inclined downward toward the recess 71, and the plurality of grooves 52 are formed so as to extend the inclined surface 72 to the bottom of the recess 71. ing. Thereby, the water and chemical | medical solution in the recessed part 71 are easy to be guide | induced to the lower end part of the discharge pipe 43B (discharge member 42) through each groove | channel 52. FIG. The surface of the recess 71 on the base 50 side is not necessarily formed on the inclined surface 72 and may be a vertical surface.

凹部７１の形状としては、特に限定されるものではなく、図示例のような平面視矩形状のほか、円状や楕円状など、種々の形状とすることができる。また、凹部７１の大きさとしては、特に限定されるものではなく、必ずしも、図示例のように、左右方向における幅ｄ２を複数の溝５２の幅Ｄよりも大きくする必要はない。左右方向における幅ｄ２を複数の溝５２の幅Ｄよりも小さくし、複数の溝５２の少なくとも一部だけを凹部７１に接続するようにしてもよい。また、凹部７１（貯留部７）の内容積としては、特に限定されるものではないが、１回のフラッシュにより、水置換現象を起こす水や薬液の量が０．１ｍｌ〜３．０ｍｌ、好ましくは０．２ｍｌ〜２．６ｍｌ、さらに好ましくは０．２ｍｌ〜１．０ｍｌ程度となるように、凹部７１（貯留部７）の内容積が設定されていることが好ましい。 The shape of the recess 71 is not particularly limited, and may be various shapes such as a circular shape and an elliptical shape in addition to a rectangular shape in plan view as shown in the illustrated example. Further, the size of the recess 71 is not particularly limited, and the width d2 in the left-right direction is not necessarily larger than the width D of the plurality of grooves 52 as in the illustrated example. The width d2 in the left-right direction may be smaller than the width D of the plurality of grooves 52, and at least a part of the plurality of grooves 52 may be connected to the recess 71. Further, the internal volume of the recess 71 (reservoir 7) is not particularly limited, but the amount of water or chemical that causes a water substitution phenomenon by one flush is preferably 0.1 ml to 3.0 ml. Is preferably set so that the inner volume of the recess 71 (reservoir 7) is about 0.2 ml to 2.6 ml, more preferably about 0.2 ml to 1.0 ml.

第２実施形態の薬液供給部材５”を備えた薬液供給装置１においても、フラッシュ時に給水受皿１００の供給された流水が、開口３３より支持体３内に流入して各保持部５１上の薬液を洗い流す際に、その一部が薬液とともに各凹部７１内に流れ込むことで貯留部７に貯留される。よって、フラッシュ後に薬液容器２内が負圧になったとき、貯留部７内の水や薬液が各溝５２を介して調整部材４内へと流れ込み、排出管４３Ｂの下端部から吸引されて薬液容器２内に逆流する結果、水置換現象が起こる。 Also in the chemical solution supply apparatus 1 including the chemical solution supply member 5 ″ of the second embodiment, the flowing water supplied to the water supply tray 100 flows into the support 3 from the opening 33 during the flushing, and the chemical solution on each holding portion 51 is supplied. When the water is washed away, a part of the liquid flows into the recesses 71 together with the chemical solution, and is stored in the storage unit 7. Therefore, when the inside of the chemical solution container 2 becomes negative pressure after flushing, As a result of the chemical liquid flowing into the adjusting member 4 through the respective grooves 52 and sucked from the lower end of the discharge pipe 43B and back flowing into the chemical liquid container 2, a water replacement phenomenon occurs.

このように、第２実施形態の薬液供給部材５”においても、室温が水温よりも低い場合に、フラッシュ後に薬液容器２内が負圧になった際には、フラッシュ時の水や薬液が貯留部７に貯留されて排出管４３Ｂの周辺に残存している。そのため、フラッシュ後に、水置換現象を確実に起こすことができる結果、薬液容器２内の薬液の減少を緩やかなものとすることができ、第２実施形態の薬液供給装置１においても、薬液を長期間安定して供給することが可能である。また、水置換現象により薬液容器２内に吸引される水や薬液の量を調整することにより、薬液容器２内の薬液がフラッシュの度に極度に希釈されるのを防止することができる。 Thus, also in the chemical solution supply member 5 ″ of the second embodiment, when the room temperature is lower than the water temperature and the inside of the chemical solution container 2 becomes a negative pressure after flushing, water or chemical solution at the time of flushing is stored. It is stored in the portion 7 and remains in the vicinity of the discharge pipe 43B.Therefore, after the flushing, the water replacement phenomenon can be surely caused, and as a result, the decrease in the chemical solution in the chemical solution container 2 may be moderated. In addition, the chemical solution can be stably supplied for a long period of time in the chemical solution supply apparatus 1 of the second embodiment, and the amount of water or chemical solution sucked into the chemical solution container 2 is adjusted by the water replacement phenomenon. By doing so, it can prevent that the chemical | medical solution in the chemical | medical solution container 2 is diluted extremely every time it flushes.

以上、本発明の第２実施形態について詳述したが、第２実施形態の具体的な態様は上記態様に限定されない。例えば、本実施形態では、凹部７１は、各保持部５１の基部５０との境目に設けられているが、凹部７１の設置場所は、何もこれに限られるものではなく、各保持部５１の基部５０との境目から所定間隔離れた場所に凹部７１を設けるように構成してもよい。この場合には、複数の溝５２の全てまたは少なくとも一部が凹部７１に接続されるように各保持部５１上面にも溝５２を形成する。また、本実施形態では、凹部７１が各保持部５１に１つずつ設けられているが、各保持部５１に凹部７１を複数ずつ設けるように構成してもよく、また、どちらか一方の保持部５１にのみ凹部７１を１つまたは複数設けるように構成してもよい。なお、凹部７１が薬液供給部材５”に複数設けられる場合（各保持部５１に１つずつ設けられる場合も含む）には、凹部７１（貯留部７）の内容積としては、複数の凹部７１のトータルで、１回のフラッシュにより、水置換現象を起こす水や薬液の量が上記した量（０．１ｍｌ〜３．０ｍｌ程度）となるように設定される。また、薬液供給部材５”に溝５２が１つだけ形成され、この１つの溝５２だけが貯留部７と排出管４３Ｂ（排出部材４２）の下端部とを流通可能にするように構成してもよい。 As mentioned above, although 2nd Embodiment of this invention was explained in full detail, the specific aspect of 2nd Embodiment is not limited to the said aspect.

In this case, the grooves 52 are also formed on the upper surfaces of the holding portions 51 so that all or at least some of the plurality of grooves 52 are connected to the recesses 71. In this embodiment, one recess 71 is provided in each holding portion 51. However, a plurality of recesses 71 may be provided in each holding portion 51, and either one of the holding portions 51 may be held. You may comprise so that the recessed part 71 may be provided only in the part 51 or one or more. In addition, when multiple recessed parts 71 are provided in the chemical | medical solution supply member 5 "(including the case where one is provided in each holding part 51), as the internal volume of the recessed part 71 (storage part 7), several recessed parts 71 are used. In total, the amount of water or chemical that causes the water replacement phenomenon is set to the above-mentioned amount (about 0.1 ml to 3.0 ml) by one flush.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. Here, the chemical liquid supply apparatus 1 using the chemical liquid supply member 5 ′ shown in FIG. 1 is used as an example, and the chemical liquid supply apparatus 10 using the conventional chemical liquid supply member 5 shown in FIG. 11 is used as a comparative example. . In addition, the structure of the chemical | medical solution supply apparatus in an Example and a comparative example is the same except a chemical | medical solution supply member. And when these chemical | medical solution supply apparatuses were used, the residual amount of the chemical | medical solution which remains in a chemical | medical solution container for every flash | flush was measured. The experimental method is as follows. The weight of the chemical solution filled in the chemical solution container at the beginning of the experiment was 73 g.
1. The chemical solution supply device to which each chemical solution supply member is attached is installed in a water-washing tray for hand-washing provided at the upper part of a water storage tank of a flush toilet S721B manufactured by TOTO Corporation.
2. Operate the water tank lever at a rate of once per hour, flush, and measure the weight of the chemical supply device every time the flush is performed a predetermined number of times (20 to 28 times). The remaining amount of chemical solution was derived. The experiment was performed under the following two conditions with different room temperature and water temperature.

薬液としては、界面活性剤、香料、および水からなる水洗トイレ用芳香洗浄剤を基本となる薬液として用い、粘度が２５℃において１２５ｍＰａ・ｓ、５℃において５３０ｍＰａ・ｓのものを用いた。なお、粘度は、Ｂ型粘度計（東機産業株式会社製：型番ＴＶＢ−１０形粘度計）において、設定温度２５℃または５℃で、ローターＮｏ．２、攪拌条件３０ｒｐｍ、攪拌時間１分の条件において測定した。 As a chemical solution, a fragrance cleaning agent for a flush toilet composed of a surfactant, a fragrance, and water was used as a basic chemical solution, and a viscosity of 125 mPa · s at 25 ° C. and 530 mPa · s at 5 ° C. was used. In addition, the viscosity is set to 25 ° C. or 5 ° C. in the B type viscometer (manufactured by Toki Sangyo Co., Ltd .: model number TVB-10 type viscometer). 2. Measurement was performed under the conditions of stirring at 30 rpm and stirring time of 1 minute.

以下、実験結果について説明する。図５および図６は、フラッシュの回数と薬液の残量の関係を示すグラフであり、図５は実験１の結果、図６は実験２の結果を、それぞれ示している。 Hereinafter, experimental results will be described. 5 and 6 are graphs showing the relationship between the number of flushes and the remaining amount of the chemical solution. FIG. 5 shows the result of Experiment 1 and FIG. 6 shows the result of Experiment 2, respectively.

（１）実験１：室温１９℃、水温２２℃
この実験１によれば、室温が水温よりも低いため、比較例では上述したように、フラッシュの度に水置換現象が起こらない。そのため、図５の点線で示すように、薬液残量の低下が早まり、装置の使用回数が少なくなっている。これに対して、実施例では、図５の実線で示すように、使用初期から中期において薬液残量の低下が緩やかであり、最終的に比較例よりも使用回数が大幅に多くなっている。これは、実施例では、使用初期および中期において、フラッシュの度に薬液容器内に貯留部の水や薬液が流入することで、薬液容器内の薬液の減少が非常に緩やかになっているためであり、本発明に係る薬液供給装置１では水置換現象が生じていることが明らかに確認できる。よって、本発明に係る薬液供給装置１では、室温が水温よりも低い場合において、比較例の薬液供給装置１０よりも使用回数を多くすることができ、薬液を長期間安定して供給可能であることが確認された。 (1) Experiment 1: room temperature 19 ° C, water temperature 22 ° C
According to Experiment 1, since the room temperature is lower than the water temperature, in the comparative example, as described above, the water replacement phenomenon does not occur at each flush. Therefore, as shown by the dotted line in FIG. 5, the remaining amount of the chemical solution is rapidly reduced, and the number of times the apparatus is used is reduced. In contrast, in the example, as shown by the solid line in FIG. 5, the decrease in the remaining amount of the chemical solution is moderate from the initial use to the middle period, and finally the number of uses is significantly greater than in the comparative example. This is because, in the examples, in the initial and middle periods of use, the decrease in the chemical solution in the chemical solution container becomes very gradual due to the water or chemical solution in the reservoir flowing into the chemical solution container every time the flash is used. In addition, it can be clearly confirmed that the water replacement phenomenon occurs in the chemical solution supply apparatus 1 according to the present invention. Therefore, in the chemical solution supply device 1 according to the present invention, when the room temperature is lower than the water temperature, the number of times of use can be increased as compared with the chemical solution supply device 10 of the comparative example, and the chemical solution can be stably supplied for a long time. It was confirmed.

なお、使用後期において、薬液残量が著しく低下している理由は、使用初期および中期において水置換現象により、薬液容器内に水や薬液が流入しているため、使用後期には薬液容器内の薬液が水で薄められてその粘度が低下する結果、薬液が薬液容器から一気に排出されるためである。 The reason why the remaining amount of the chemical solution is significantly reduced in the latter period of use is that water and chemicals are flowing into the chemical container due to the water replacement phenomenon in the early and middle periods of use. This is because the chemical solution is diluted with water and its viscosity is lowered, and as a result, the chemical solution is discharged from the chemical solution container at once.

（２）実験２：室温１５℃、水温５℃
この実験２によれば、水温が室温よりも低いため、図６に示すように、実施例（実線で示す）および比較例（点線で示す）ともに、フラッシュの度に水置換現象が起こるため、使用初期から中期において薬液残量の低下が緩やかであり、薬液容器内の薬液の減少が非常に緩やかになっているが、実施例では、比較例と比べて、薬液残量の低下がさらに緩やかになっていて、その結果、使用回数が大幅に多くなっている。よって、本発明に係る薬液供給装置１では、水温が室温よりも低い場合においても、比較例の薬液供給装置１０よりも使用回数を多くすることができ、薬液を長期間安定して供給可能であることが確認された。 (2) Experiment 2: room temperature 15 ° C., water temperature 5 ° C.
According to this experiment 2, since the water temperature is lower than room temperature, as shown in FIG. 6, in both the example (shown by a solid line) and the comparative example (shown by a dotted line), a water substitution phenomenon occurs at each flash, The decrease in the remaining amount of the chemical solution from the initial use to the mid-term is gradual, and the decrease in the chemical solution in the chemical solution container is very gradual. As a result, the number of uses is significantly increased. Therefore, in the chemical solution supply apparatus 1 according to the present invention, even when the water temperature is lower than room temperature, the number of times of use can be increased as compared with the chemical solution supply apparatus 10 of the comparative example, and the chemical solution can be stably supplied for a long period of time. It was confirmed that there was.

以上のとおり、本発明に係る薬液供給装置１では、室温が水温よりも低い場合に加えて、さらに、室温が水温よりも高い場合においても、従来例の薬液供給装置１０よりも、使用回数を多くでき、薬液を長期間安定して供給可能であることが確認された。 As described above, in the chemical solution supply apparatus 1 according to the present invention, in addition to the case where the room temperature is lower than the water temperature, the number of times of use is higher than that of the conventional chemical supply device 10 even when the room temperature is higher than the water temperature. It was confirmed that the chemical solution can be supplied stably for a long period of time.

以上、本発明の実施形態について詳述したが、本発明の具体的な態様は上記した実施形態に限定されない。例えば、貯留部７を図７に示すような細管７４により構成することもできる。図７では、調整部材４の上面部４０Ａ（上段部４０ｂ）に入水孔７３を設け、細管７４により、入水孔７３から入水する水を排出管４３Ｂの下端部の周辺に導くように構成されている。細管７４は、排出管４３Ｂの下端部側の端部に向かうにつれて先細り形状に形成されて、入水孔７３から入水する水が細管７４内にある程度の時間貯留されるように構成されている。この図７の例では、フラッシュ時、給水受皿の供給される水の一部が、薬液容器２と支持体３との嵌合部分から薬液容器２の下面に伝って支持体内に浸入した後、調整部材４の上面部４０Ａ上に落下するおそれがあるが、この水を入水孔７３から細管７４を介して排出管４３Ｂ（排出部材４２）の下端部の周辺に導くことで、水置換現象を生じさせることが可能になっている。 As mentioned above, although embodiment of this invention was explained in full detail, the specific aspect of this invention is not limited to above-described embodiment. For example, the storage part 7 can also be comprised by the thin tube 74 as shown in FIG. In FIG. 7, a water inlet 73 is provided in the upper surface portion 40A (upper portion 40b) of the adjustment member 4, and the narrow pipe 74 is configured to guide water entering from the water inlet 73 to the periphery of the lower end of the outlet pipe 43B. Yes. The narrow tube 74 is formed in a tapered shape toward the end on the lower end side of the discharge tube 43B, and is configured such that water entering from the water inlet 73 is stored in the narrow tube 74 for a certain period of time. In the example of FIG. 7, at the time of flushing, after a part of the water supplied to the water supply tray has entered the support body from the fitting portion between the chemical liquid container 2 and the support body 3 to the lower surface of the chemical liquid container 2, Although there is a possibility of dropping onto the upper surface portion 40A of the adjusting member 4, this water is introduced from the water inlet hole 73 to the periphery of the lower end portion of the discharge pipe 43B (discharge member 42) through the narrow pipe 74, thereby reducing the water substitution phenomenon. It is possible to make it happen.

また、上記した実施形態では、水洗トイレの貯水タンク上に配置されるタイプの薬液供給装置を例に説明しているが、便器のリムに吊り掛けられて使用されるタイプの薬液供給装置についても、本発明を好適に適用することができる。 Further, in the above-described embodiment, the chemical liquid supply device of the type disposed on the water storage tank of the flush toilet has been described as an example, but the chemical liquid supply device of the type used by being hung on the toilet rim is also described. The present invention can be preferably applied.
