That is, when the temperature rises and the pressure in the chemical solution container 100 increases, the chemical solution in the chemical solution container 100 flows out from the communication hole 108 and flows into the buffer chamber 106. On the other hand, when the temperature decreases and the pressure in the chemical solution container 100 decreases, the chemical solution in the buffer chamber 106 is drawn back into the chemical solution container 100 through the communication hole 108. By such an action, it is possible to prevent the chemical liquid from being unnecessarily discharged from the chemical liquid supply device even if the temperature change is repeated.

It is also possible to provide a mechanism for supplying the chemical solution directly to the water storage tank.
- the water that has fallen onto the chemical liquid container 2 from the water supply pipe on the water supply tray flows down along the surface of the chemical liquid container 2 and is transmitted to the fitting portion T between the chemical liquid container 2 and the support body 3.

- the air circulation hole 62 is provided at the upper end portion of the side wall of the buffer chamber 60, even when the water supplied to the water supply tray during the flushing enters the support 3 from below, the water gets on the side wall. As a result, it is difficult to reach the air circulation hole 62 and as a result, the air circulation hole 62 is prevented from entering the buffer chamber 60. Therefore, it is possible to prevent the chemical solution stored in the buffer chamber 60 from being diluted.

Therefore, even if the cover member 4 and the support 3 are not completely fitted and a gap is generated between the outer wall 32 and the inner wall 41, the opening of the gap to the outside of the buffer chamber 60 is not buffered. It will be located at the upper end of the side wall of the chamber 60. As a result, even if the water supplied to the water supply tray during flushing enters the support 3 from below, the side wall becomes a high wall and hardly reaches the opening of the gap. Intrusion into the buffer chamber 60 is prevented. Therefore, it is possible to prevent the chemical solution stored in the buffer chamber 60 from being diluted.
- the cover member 4 further includes a surrounding wall 43 that covers the upper side of the air circulation hole 62. Therefore, even if water enters the support 3 from above through the lower end surface of the chemical solution container 2 from the fitting portion T, the water reaches the air circulation hole 62 because the surrounding wall 43 functions as a ridge. Can be reliably prevented. Therefore, as a result of preventing water from entering the buffer chamber 60, the chemical solution stored in the buffer chamber 60 can be prevented from being diluted. In addition, although the intrusion prevention effect of the water by this surrounding wall 43 can also be acquired only by the extension part 43a, it is strengthened by providing the drooping wall part 43b.

Description
本発明は、断続的に流下する水などの液体に薬液を供給する薬液供給装置に関し、例えば、水洗トイレの貯水タンク上部に設けられた手洗い用の給水受皿に設置されて、あるいは、便器のリムに取り付けられて、芳香、消臭、洗浄のための薬液を水洗用の水に供給する薬液供給装置に関するものである。
The present invention relates to a chemical solution supply apparatus that supplies a chemical solution to a liquid such as water that flows intermittently. For example, the chemical solution supply device is installed in a water receiving tray for a hand-washing provided in a water storage tank of a flush toilet, or It is related with the chemical | medical solution supply apparatus which is attached to and supplies the chemical | medical solution for fragrance, deodorizing, and washing | cleaning to the water for washing.
この種の薬液供給装置としては、例えば、図23~図25の例、および、図26~図28の例に示すように、薬液を収容する薬液容器100と、薬液容器100を支持するカップ状の支持体101とを備え、支持体101の下部に設けられた案内部材102が貯水タンクに流入する水と接触するように、貯水タンク上部の給水受皿に設置されるタイプのものが提案されている(例えば、特許文献1,2参照)。
As this type of chemical solution supply apparatus, for example, as shown in the examples of FIGS. 23 to 25 and the examples of FIGS. 26 to 28, a chemical solution container 100 that stores the chemical solution, and a cup shape that supports the chemical solution container 100 is used. And a support member 101 of the type that is installed in a water tray in the upper part of the water storage tank so that the guide member 102 provided in the lower part of the support body 101 comes into contact with the water flowing into the water storage tank has been proposed. (For example, see Patent Documents 1 and 2).
支持体101は、支持体101内に着脱可能に取り付けられるカバー部材105を備えており、カバー部材105は、薬液容器100の排出口に接続される排出部材103を備えている。薬液容器100内の薬液は、排出部材103の接続部110から細管部111を通じて、下端の流通孔104から案内部材102に供給される。また、支持体101には、薬液容器100から排出される薬液の量を調整する調整機構112が設けられている。この調整機構112は、水との接触などにより薬液容器100の温度が変動したときに、容器の内圧が変化しても、薬液容器100から案内部材102への薬液の余分な流出やその逆流が生じるのを防止するものであり、支持体101とカバー部材105との間に区画形成された薬液を貯留可能な緩衝室106と、緩衝室106に空気を流入可能な空気流通孔107と、緩衝室106および排出部材103を連通させる連通孔108とを備えている。
The support body 101 includes a cover member 105 that is detachably attached to the support body 101, and the cover member 105 includes a discharge member 103 connected to the discharge port of the chemical solution container 100. The chemical solution in the chemical solution container 100 is supplied from the connecting portion 110 of the discharge member 103 through the narrow tube portion 111 to the guide member 102 from the lower through hole 104. The support 101 is provided with an adjustment mechanism 112 that adjusts the amount of the chemical liquid discharged from the chemical liquid container 100. This adjusting mechanism 112 prevents excessive outflow or reverse flow of the chemical solution from the chemical solution container 100 to the guide member 102 even when the internal pressure of the chemical solution container 100 changes when the temperature of the chemical solution container 100 changes due to contact with water or the like. The buffer chamber 106 that can store the chemical solution defined between the support 101 and the cover member 105, the air circulation hole 107 that can flow air into the buffer chamber 106, and the buffer A communication hole 108 for communicating the chamber 106 and the discharge member 103 is provided.
上記構成の薬液供給装置は、次のように作用する。すなわち、温度が上昇し、薬液容器100内の圧力が上昇した場合には、薬液容器100内の薬液は、連通孔108から流れ出して緩衝室106内に流入する。一方、温度が低下し、薬液容器100内の圧力が低下すると、緩衝室106内の薬液が連通孔108を介して薬液容器100内へ引き戻される。このような作用により、温度変化の繰り返しがあっても、薬液が無駄に薬液供給装置から流出するのを防止できる。特に、薬液容器100の温度変化は、室温の変化および給水受皿へ供給される流水との接触の双方で生じるので、これによる薬液の無駄な流出を防止することは、薬液の安定供給を可能にする上で重要である。このように、上記構成の薬液供給装置は、緩衝室106を設けることにより、薬液の余分な流出が防止され、その結果、薬液容器100から薬液を正確な量で排出することが可能となって、安定供給を実現できる。
The chemical solution supply apparatus having the above configuration operates as follows. That is, when the temperature rises and the pressure in the chemical solution container 100 increases, the chemical solution in the chemical solution container 100 flows out from the communication hole 108 and flows into the buffer chamber 106. On the other hand, when the temperature decreases and the pressure in the chemical solution container 100 decreases, the chemical solution in the buffer chamber 106 is drawn back into the chemical solution container 100 through the communication hole 108. By such an action, it is possible to prevent the chemical liquid from being unnecessarily discharged from the chemical liquid supply device even if the temperature change is repeated. In particular, the temperature change of the chemical solution container 100 occurs both due to the change in the room temperature and the contact with the flowing water supplied to the water supply tray, and thus preventing the wasteful discharge of the chemical solution enables stable supply of the chemical solution. It is important to do. As described above, the chemical solution supply apparatus having the above-described configuration is provided with the buffer chamber 106, thereby preventing an excessive outflow of the chemical solution. As a result, the chemical solution can be discharged from the chemical solution container 100 in an accurate amount. , Stable supply can be realized.
しかしながら、上記構成の薬液供給装置では、緩衝室106が以下の構造になっているため、緩衝室106内に水が浸入する問題を生じることがあった。つまり、薬液供給装置は、薬液容器100が支持体101に嵌合されることで支持体101に装着されて、例えば、給水受皿上の給水管の下方に配置される。そして、使用時に、給水管から薬液容器100上に落下した水の一部が、薬液容器100の表面に沿って流れ落ちて薬液容器100と支持体101との嵌合部分Tまで伝わると、この嵌合部分Tに不可避的に生じる隙間から水が支持体101内に浸入するおそれがある。支持体101内に浸入した水は、薬液容器100の下面に沿って支持体101の中央部付近の緩衝室106上まで伝わった後、落下する。この場合、上記構成の薬液供給装置のように、空気流通孔107が緩衝室106の上部を覆う上壁109に設けられていると、流れ落ちた水がこの空気流通孔107から緩衝室106内に浸入するおそれがある。緩衝室106内に水が浸入すると、その水によって緩衝室106内の薬液が薄められ、薄められた薬液が温度変化により薬液容器100内に吸収される結果、薬液容器100内の薬液まで希釈されることになる。これでは、適正な薬液量による薬効が妨げられるばかりか、薬液によっては本来の粘度が低下し、薬液容器100の排出口から過剰に流出して安定供給を損ねることもある。
However, in the chemical solution supply apparatus configured as described above, since the buffer chamber 106 has the following structure, there is a problem that water enters the buffer chamber 106. That is, the chemical solution supply device is attached to the support 101 by fitting the chemical solution container 100 to the support 101, and is disposed, for example, below the water supply pipe on the water supply tray. In use, when a part of the water dropped from the water supply pipe onto the chemical liquid container 100 flows down along the surface of the chemical liquid container 100 and reaches the fitting portion T between the chemical liquid container 100 and the support 101, this fitting is performed. There is a risk that water may enter the support 101 through a gap inevitably generated in the joint portion T. The water that has entered the support body 101 falls along the lower surface of the chemical solution container 100 onto the buffer chamber 106 near the center of the support body 101 and then falls. In this case, if the air circulation hole 107 is provided in the upper wall 109 that covers the upper portion of the buffer chamber 106 as in the chemical solution supply apparatus having the above configuration, the water that has flowed down enters the buffer chamber 106 from the air circulation hole 107. There is a risk of intrusion. When water enters the buffer chamber 106, the chemical solution in the buffer chamber 106 is diluted by the water, and the diluted chemical solution is absorbed into the chemical solution container 100 due to a temperature change. As a result, the chemical solution in the chemical solution container 100 is diluted. Will be. This not only prevents the medicinal effect due to the appropriate amount of the chemical solution, but also lowers the original viscosity depending on the chemical solution, and may flow out excessively from the discharge port of the chemical solution container 100 and impair stable supply.
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 tray in the upper part of the water storage tank, but also in the chemical solution supply device of the type attached to the rim of the toilet bowl.
本発明は、上記した問題に着目してなされたものであり、薬液容器と支持体との嵌合部分から内部に水が浸入した場合でも、緩衝室内に水が浸入して薬液が薄められるのを効果的に防止することができ、安定して薬液を供給することのできる薬液供給装置を提供することを目的とする。
The present invention has been made paying attention to the above-described problems, and even when water enters the inside from the fitting portion between the chemical solution container and the support, the water enters the buffer chamber and the chemical solution is diluted. It is an object of the present invention to provide a chemical liquid supply device that can effectively prevent the chemical liquid and can stably supply the chemical liquid.

The above object of the present invention includes a chemical solution container that contains a chemical solution therein and has a chemical solution discharge port, and a support body to which the chemical solution container is detachably attached, and the support member includes the discharge port. A discharge member that discharges the chemical solution in the chemical solution container to the outside, and an adjustment mechanism that adjusts the amount of the chemical solution discharged from the chemical solution container, wherein the adjustment mechanism includes a bottom wall, an upper wall, and a side wall.

上記構成の薬液供給装置において、断続的に流下する水などの流体の一部が薬液容器上に落下すると、薬液容器の表面に沿って流れ落ちて薬液容器と支持体との嵌合部分まで伝わり、この嵌合部分に不可避的に生じる隙間から流体が支持体内に浸入するおそれがある。しかしながら、上記構成の薬液供給装置では、空気流通孔が、緩衝室の上部を覆う上壁に設けられているのではなく、緩衝室の側壁に設けられているので、空気流通孔から緩衝室内に当該流体が浸入することを防止できる。よって、内部に貯留された薬液が薄められることを防止でき、薬液容器から排出される薬液濃度を適正に保つことができる。
In the chemical solution supply apparatus configured as described above, when a part of fluid such as water that flows intermittently falls on the chemical solution container, it flows down along the surface of the chemical solution container and is transmitted to the fitting portion between the chemical solution container and the support, There is a possibility that fluid may enter the support body through a gap inevitably generated in the fitting portion. However, in the chemical solution supply apparatus configured as described above, the air circulation hole is not provided in the upper wall that covers the upper portion of the buffer chamber, but is provided in the side wall of the buffer chamber. It is possible to prevent the fluid from entering. Therefore, it can prevent that the chemical | medical solution stored inside is diluted, and can maintain the chemical | medical solution density | concentration discharged | emitted from a chemical | medical solution container appropriately.
本発明の好ましい実施態様においては、前記空気流通孔は、前記側壁の上端部に設けられていることを特徴としている。この実施態様によれば、例えば、流体が下方から支持体内へ浸入した場合でも、流体は側壁を乗り超えて空気流通孔に到達し難いため、流体が空気流通孔から緩衝室内に浸入するのを防止できる。よって、緩衝室内に貯留された薬液が薄められることを防止できる。
In a preferred embodiment of the present invention, the air circulation hole is provided in an upper end portion of the side wall.

上記した実施態様において、カバー部材の第2の周壁が、支持体の下部材の第1の周壁の内側に嵌合する構造となっていると、仮に、カバー部材と支持体との嵌合が完全ではなく、第1、2の周壁の間に隙間が生じたとしても、その隙間の緩衝室外側に対する開口は、緩衝室の側壁の上端部に位置することとなる。その結果、例えば、流体が下方から支持体内へ浸入した場合でも、流体は側壁が高い壁となって当該隙間の開口には到達し難いため、当該隙間を伝って下側から緩衝室内に浸入するのを防止できる。よって、緩衝室内に貯留された薬液が薄められることを防止できる。
In the above-described embodiment, if the second peripheral wall of the cover member is configured to fit inside the first peripheral wall of the lower member of the support body, the cover member and the support body are temporarily fitted. Even if there is a gap between the first and second peripheral walls, the opening to the outside of the buffer chamber is located at the upper end of the side wall of the buffer chamber. As a result, for example, even when the fluid enters the support body from below, the fluid has a high side wall and hardly reaches the opening of the gap, and therefore enters the buffer chamber from below through the gap. Can be prevented. Therefore, it is possible to prevent the drug solution stored in the buffer chamber from being diluted.
本発明のさらに好ましい実施態様においては、前記第2の周壁は、前記第1の周壁の内側に嵌合しており、前記空気流通孔は、前記第2の周壁に設けられた上下方向に延びるスリットまたは貫通穴と、前記第1の周壁の前記スリットまたは前記貫通穴に対応する位置に設けられたスリットまたは貫通穴とにより形成されていることを特徴としている。この実施態様において、例えば、スリットおよび貫通穴で空気流通孔を形成すれば、前記第1の周壁に設ける貫通穴の位置を上下させるだけで、空気流通穴の位置を適宜変更することができる。なお、スリットおよびスリット、貫通穴および貫通穴の組み合わせで空気流通孔を形成してもよい。

In addition, you may form an air circulation hole with the combination of a slit and a slit, a through-hole, and a through-hole.
本発明のさらに好ましい実施態様においては、前記空気流通孔の上方を覆う庇部材をさらに備えていることを特徴としている。この実施態様によれば、薬液容器および支持体の嵌合部分から支持体内に流体が浸入してきても、庇部材が庇として機能することで空気流通孔に流体が到達するのを確実に阻止することができる。よって、緩衝室内に流体が浸入するのを防止でき、緩衝室内に貯留された薬液が薄められることを防止できる。
In a further preferred embodiment of the present invention, it is further characterized by further comprising a gutter member that covers the upper part of the air circulation hole.

In a further preferred aspect of the present invention, the support body has an outer shape whose length in the first direction is longer than the length in the second direction orthogonal to the length in a plan view. The hole is provided at a position facing the first direction.
この実施態様は、前記支持体が、平面視において、第1の方向の長さがこれと直交する第2の方向の長さよりも長い外形を有していると、薬液容器の表面を流れる流体は、第2の方向の両側に位置する嵌合部分から支持体内により浸入し易いことに鑑みてなされたものであり、当該嵌合部分から最も離れた位置に前記空気流通孔が設けることで、当該嵌合部分から支持体内に流体が浸入したとしても、空気流通孔の位置まで到達する流体の量を抑制することができる。よって、緩衝室内への流体の浸入を抑制することができ、緩衝室内に貯留された薬液が薄められることを防止できる。
In this embodiment, when the support has an outer shape whose length in the first direction is longer than the length in the second direction orthogonal to the length in plan view, the fluid flowing on the surface of the chemical container Is made in view of the fact that it easily enters the support body from the fitting portions located on both sides in the second direction, and the air circulation hole is provided at a position farthest from the fitting portion, Even if fluid enters the support body from the fitting portion, the amount of fluid reaching the position of the air circulation hole can be suppressed.

The arrangement of the air circulation holes 62 is not necessarily limited to this embodiment, and can be provided at any position on the side wall of the buffer chamber 60. In the present embodiment, the air circulation hole 62 is provided at the upper end of the side wall of the buffer chamber 60, but it can also be provided at a position below the upper end. However, it is not preferable that the water supply tray is arranged too low, because when the water supplied to the water supply tray enters the support 3, the water may enter the buffer chamber 60 through the air circulation hole 62. . In the present embodiment, the air flow holes 62 are formed by providing the longitudinal slits 64 in the inner wall 41. However, the inner wall 41 is provided with through holes in the same manner as the outer wall 32, and the through holes are formed between the through holes. May be formed so that the air circulation holes 62 are formed. Further, the air flow hole 62 may be formed by providing a through hole in the inner wall 41 and providing a longitudinal slit in the outer wall 32, and further by providing a longitudinal slit in both the inner wall 41 and the outer wall 32. The air circulation hole 62 may be formed. Moreover, in this embodiment, although the air circulation hole 62 has faced the horizontal direction, you may form it so that it may become downward (diagonally downward) rather than a horizontal direction.
上記した調整機構6は、薬液容器2の温度変化に対して次のように作用をする。例えば、温度が上昇して薬液容器2が暖められた場合には、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21から排出されるが、排出された薬液は、細管部42bから導出路に流れ込む他、連通孔61を介して緩衝室60にも流れ込むため、薬液が前記導出路へ過剰に流出するのが防止される。
The adjustment mechanism 6 described above acts as follows on the temperature change of the chemical solution container 2. For example, when the temperature rises and the chemical liquid container 2 is warmed, the air in the chemical liquid container 2 expands and the chemical liquid container 2 has a positive pressure. In this case, the chemical solution in the chemical solution container 2 is pushed out and discharged from the discharge port 21, but the discharged chemical solution flows into the lead-out path from the thin tube portion 42 b and also flows into the buffer chamber 60 through the communication hole 61. Therefore, it is possible to prevent the chemical liquid from flowing out excessively into the outlet path.
一方、流水で冷やされるなどして、薬液容器2の温度が低下すると、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、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内へ吸い込まれる。したがって、案内部材5上の水または薄められた薬液が細管部42bを通って薬液容器2側に戻されるのが抑制される。また、薬液容器2内の負圧によって薬液の排出が制限されるのが防止される。このように、調整機構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、あるいは、流出が制限されるのを防止することができる。
On the other hand, when the temperature of the chemical solution container 2 is lowered by being cooled by running water, the air in the chemical solution container 2 contracts and the inside of the chemical solution container 2 becomes negative pressure. In this case, the chemical solution in the buffer chamber 60 that is at atmospheric pressure or indoor pressure due to the action of the air circulation hole 62 is sucked into the chemical solution container 2 through the communication hole 61. Therefore, it is suppressed that the water on the guide member 5 or the diluted chemical solution is returned to the chemical solution container 2 side through the thin tube portion 42b. Further, the discharge of the chemical liquid is prevented from being restricted by the negative pressure in the chemical liquid container 2. Thus, even when a pressure change occurs in the chemical solution container 2 due to a temperature change, the adjustment mechanism 6 causes the chemical solution to flow between the chemical solution container 2 and the buffer chamber 60. Can be prevented from flowing out excessively or being restricted from flowing out.
上記構成の薬液供給装置1は、カバー部材4の内側壁41の外側に、支持体3の外側壁32を嵌合して緩衝室60を形成した後、カバー部材4から上方へ延びる排出部材42の接続部42aを薬液容器2の排出口21にキャップ22を貫通して嵌入することにより組み立てられる。そして、水洗トイレ用貯水タンクの給水受皿の排水孔に支持体3の長脚部36を挿入する。これにより、薬液容器2内の薬液は、接続部42aから細管部42bに流入して導出路から案内部材5に排出され、案内部材5上の薬液がフラッシュ時に給水受皿に供給される水に洗い流されて、排水孔から貯水タンクに流れ込む。なお、上記構成の薬液供給装置1は、案内部材5上の薬液がフラッシュ時に給水受皿に供給される水に洗い流されることのない場合にも、経時的に薬液を吐出し、薬液容器2内の薬液を直接貯水タンクに供給する機構を備えることもできる。
In the chemical solution supply apparatus 1 having the above-described configuration, after the outer wall 32 of the support 3 is fitted to the outer side of the inner wall 41 of the cover member 4 to form the buffer chamber 60, the discharge member 42 extending upward from the cover member 4. The connecting portion 42a is assembled by inserting the cap 22 through the outlet 21 of the chemical liquid container 2 and inserting it. And the long leg part 36 of the support body 3 is inserted in the drainage hole of the water receiving tray of the water storage tank for flush toilets. Thereby, the chemical solution in the chemical solution container 2 flows into the narrow tube portion 42b from the connection portion 42a and is discharged to the guide member 5 from the outlet path, and the chemical solution on the guide member 5 is washed away with water supplied to the water supply tray at the time of flushing. And flows into the water storage tank through the drainage hole. Note that the chemical solution supply device 1 having the above-described configuration also discharges the chemical solution over time even when the chemical solution on the guide member 5 is not washed away by the water supplied to the water supply tray at the time of flushing. It is also possible to provide a mechanism for supplying the chemical solution directly to the water storage tank.
このとき、給水受皿上の給水管から薬液容器2上に落下した水は、薬液容器2の表面に沿って流れ落ちて薬液容器2と支持体3との嵌合部分Tまで伝わって、この嵌合部分Tに不可避的に生じる隙間から水が支持体3内に浸入するおそれがある。しかしながら、空気流通孔62が、緩衝室60の上部を覆う上壁に設けられているのではなく、緩衝室60の側壁に、水平方向または水平方向よりも下向きを向くように設けられているので、空気流通孔62から緩衝室60内に当該水が浸入することを防止できる。よって、内部に貯留された薬液が薄められることを防止できる結果、薬液の戻りによる薬液容器2内の薬液の希釈化が防止され、薬液容器2から排出される薬液濃度を適正に保つことができる。
At this time, the water that has fallen onto the chemical liquid container 2 from the water supply pipe on the water supply tray flows down along the surface of the chemical liquid container 2 and is transmitted to the fitting portion T between the chemical liquid container 2 and the support body 3. There is a risk that water may enter the support 3 through a gap inevitably generated in the portion T. However, the air circulation hole 62 is not provided in the upper wall that covers the upper portion of the buffer chamber 60, but is provided in the side wall of the buffer chamber 60 so as to face the horizontal direction or downward in the horizontal direction. The water can be prevented from entering the buffer chamber 60 from the air circulation hole 62. Therefore, as a result of preventing the chemical liquid stored inside from being diluted, the chemical liquid in the chemical liquid container 2 is prevented from being diluted due to the return of the chemical liquid, and the concentration of the chemical liquid discharged from the chemical liquid container 2 can be appropriately maintained. .
また、空気流通孔62は、緩衝室60の側壁の上端部に設けられているため、フラッシュ時に給水受皿に供給された水が下方から支持体3内へ浸入した場合でも、水は側壁を乗り超えて空気流通孔62に到達し難く、その結果、空気流通孔62から緩衝室60内に浸入するのが防止される。よって、緩衝室60内に貯留された薬液が薄められることを防止できる。
Further, since the air circulation hole 62 is provided at the upper end portion of the side wall of the buffer chamber 60, even when the water supplied to the water supply tray during the flushing enters the support 3 from below, the water gets on the side wall. As a result, it is difficult to reach the air circulation hole 62 and as a result, the air circulation hole 62 is prevented from entering the buffer chamber 60. Therefore, it is possible to prevent the chemical solution stored in the buffer chamber 60 from being diluted.
また、空気流通孔62は、薬液容器2の表面を流れる水が支持体3内へより浸入し易い、楕円の短軸S(第2の方向)の両側に位置する嵌合部分T1からは、最も離れた位置に設けられているので、この嵌合部分T1から薬液容器2の下端面を伝って上方から支持体3内に水が浸入してきても、空気流通孔62の位置まで到達する水の量が抑制されている。その結果、緩衝室60内への水の浸入を抑制することができ、よって、緩衝室60内に貯留された薬液が薄められることを防止できる。
In addition, the air circulation holes 62 are formed from the fitting portions T1 located on both sides of the elliptical short axis S (second direction) where the water flowing on the surface of the chemical solution container 2 is more likely to enter the support 3. Since it is provided at the most distant position, even if water enters the support 3 from above through the lower end surface of the chemical liquid container 2 from the fitting portion T1, the water that reaches the position of the air circulation hole 62 is reached. The amount of is suppressed. As a result, the intrusion of water into the buffer chamber 60 can be suppressed, and thus the chemical solution stored in the buffer chamber 60 can be prevented from being diluted.
また、カバー部材4は、支持体3の外側壁32の内側に、内側壁41が嵌合する構造となっている。したがって、仮に、カバー部材4と支持体3との嵌合が完全ではなく、外側壁32と内側壁41との間に隙間が生じたとしても、その隙間の緩衝室60外側に対する開口は、緩衝室60の側壁の上端部に位置することとなる。その結果、フラッシュ時に給水受皿に供給された水が下方から支持体3内へ浸入した場合でも、側壁が高い壁となって当該隙間の開口には到達し難いため、当該隙間を伝って下側から緩衝室60内に浸入するのが防止される。よって、緩衝室60内に貯留された薬液が薄められることを防止できる。
Further, the cover member 4 has a structure in which the inner wall 41 is fitted inside the outer wall 32 of the support 3. Therefore, even if the cover member 4 and the support 3 are not completely fitted and a gap is generated between the outer wall 32 and the inner wall 41, the opening of the gap to the outside of the buffer chamber 60 is not buffered. It will be located at the upper end of the side wall of the chamber 60. As a result, even if the water supplied to the water supply tray during flushing enters the support 3 from below, the side wall becomes a high wall and hardly reaches the opening of the gap. Intrusion into the buffer chamber 60 is prevented. Therefore, it is possible to prevent the chemical solution stored in the buffer chamber 60 from being diluted.
また、カバー部材4は、空気流通孔62の上方を覆う囲繞壁43をさらに備えている。したがって、嵌合部分Tから薬液容器2の下端面を伝って上方から支持体3内に水が浸入してきても、囲繞壁43が庇として機能することで空気流通孔62に水が到達するのを確実に阻止することができる。したがって、緩衝室60内に水が浸入するのが防止される結果、緩衝室60内に貯留された薬液が薄められることを防止できる。なお、この囲繞壁43による水の侵入防止効果は、延長部43aのみによって得ることもできるが、垂下壁部43bを備えることにより強化される。
The cover member 4 further includes a surrounding wall 43 that covers the upper side of the air circulation hole 62. Therefore, even if water enters the support 3 from above through the lower end surface of the chemical solution container 2 from the fitting portion T, the water reaches the air circulation hole 62 because the surrounding wall 43 functions as a ridge. Can be reliably prevented. Therefore, as a result of preventing water from entering the buffer chamber 60, the chemical solution stored in the buffer chamber 60 can be prevented from being diluted. In addition, although the intrusion prevention effect of the water by this surrounding wall 43 can also be acquired only by the extension part 43a, it is strengthened by providing the drooping wall part 43b.
以上、本発明の一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、上記した第1実施形態では、薬液容器2の薬液収納部20および排出口21を1つとし、これに対応して支持体3に緩衝室60などを1つ設けているが、これらを各々2つ以上とすることもできる。図12および図13は、本発明を図26~図28に示した緩衝室などを2つ備える薬液供給装置に適用した例を示している。なお、基本的な構成は上記した第1実施形態の構成と同様であり、ここでは対応する構成には同一の符号を付することで詳細な説明を省略する。
As mentioned above, although one Embodiment of this invention was explained in full detail, the specific aspect of this invention is not limited to above-described embodiment. For example, in the first embodiment described above, the chemical container 20 and the discharge port 21 of the chemical container 2 are provided as one, and the buffer body 60 and the like are provided in the support 3 correspondingly. Two or more of each can be used. FIGS. 12 and 13 show an example in which the present invention is applied to a chemical solution supply apparatus having two buffer chambers and the like shown in FIGS. Note that the basic configuration is the same as the configuration of the first embodiment described above, and the corresponding components are denoted by the same reference numerals and detailed description thereof is omitted.
図26~図28に示した装置とは、空気流通孔62が設けられている位置が異なっている。すなわち、この第2実施形態においては、カバー部材18の第2の周壁41(内側壁)の上端部には、貫通穴65が形成されている。一方、支持体17の第1の周壁32(外側壁)には、カバー部材18の貫通穴65と対応する位置に貫通穴66が形成されている。これにより、カバー部材18を支持体17に装着して、貫通穴65,66を一致させることで、緩衝室60の側壁(内側壁および外側壁)に水平方向を向く空気流通孔62が形成されている。なお、空気流通孔62が水平方向よりも下向き(斜め下向き)になるように、貫通穴65,66を形成してもよい。
The position where the air circulation holes 62 are provided is different from the apparatus shown in FIGS. That is, in the second embodiment, a through hole 65 is formed in the upper end portion of the second peripheral wall 41 (inner wall) of the cover member 18. On the other hand, a through hole 66 is formed in the first peripheral wall 32 (outer wall) of the support body 17 at a position corresponding to the through hole 65 of the cover member 18. As a result, the cover member 18 is attached to the support body 17 and the through holes 65 and 66 are made to coincide with each other, so that the air circulation holes 62 facing in the horizontal direction are formed on the side walls (inner side wall and outer side wall) of the buffer chamber 60. ing. The through holes 65 and 66 may be formed so that the air circulation hole 62 is downward (obliquely downward) from the horizontal direction.
この第2実施形態においても、空気流通孔62は、緩衝室60の上部を覆う上壁ではなく、緩衝室60の側壁に、水平方向または水平方向よりも下向きを向くように設けられているので、薬液容器と支持体17との嵌合部分から薬液容器の下端面を伝って上方から支持体17内に水が浸入してきても、空気流通孔62から緩衝室60内に当該水が浸入することを防止できる。よって、緩衝室60内に貯留された薬液が薄められることを防止できる。
Also in the second embodiment, the air circulation hole 62 is provided not on the upper wall covering the upper portion of the buffer chamber 60 but on the side wall of the buffer chamber 60 so as to face the horizontal direction or downward in the horizontal direction. Even if water enters the support body 17 from above through the lower end surface of the chemical liquid container from the fitting portion between the chemical liquid container and the support body 17, the water enters the buffer chamber 60 from the air circulation hole 62. Can be prevented. Therefore, it is possible to prevent the chemical solution stored in the buffer chamber 60 from being diluted.
また、空気流通孔62は、緩衝室60の側壁の上端部に設けられているため、フラッシュ時に給水受皿に供給された水が下方から支持体17内へ浸入した場合でも、水は側壁を乗り超えて空気流通孔62に到達し難く、その結果、空気流通孔62から緩衝室60内に浸入するのが防止される。よって、緩衝室60内に貯留された薬液が薄められることを防止できる。
Further, since the air circulation hole 62 is provided at the upper end portion of the side wall of the buffer chamber 60, even when the water supplied to the water supply tray during the flushing enters the support 17 from below, the water gets on the side wall. As a result, it is difficult to reach the air circulation hole 62 and as a result, the air circulation hole 62 is prevented from entering the buffer chamber 60. Therefore, it is possible to prevent the chemical solution stored in the buffer chamber 60 from being diluted.
また、第1実施形態においては、カバー部材4は、支持体3の外側壁32(第1の周壁)の内側に、内側壁41(第2の周壁)が嵌合する内側嵌合構造となっているが、図14および図15に示すように、その逆の外側嵌合構造になっていてもよい。図14および図15は、第3実施形態に係る薬液供給装置の支持体7の構成を示している。なお、基本的な構成は上記した第1実施形態の構成と同様であり、ここでは対応する構成には同一の符号を付することで詳細な説明を省略する。
In the first embodiment, the cover member 4 has an inner fitting structure in which the inner wall 41 (second peripheral wall) is fitted inside the outer wall 32 (first peripheral wall) of the support 3. However, as shown in FIG. 14 and FIG. 15, the opposite outer fitting structure may be employed. 14 and 15 show the configuration of the support 7 of the chemical solution supply apparatus according to the third embodiment. Note that the basic configuration is the same as the configuration of the first embodiment described above, and the corresponding components are denoted by the same reference numerals and detailed description thereof is omitted.
この第3実施形態においては、支持体7の底面部30に立設される第1の周壁32が内側に位置する内側壁、カバー部材8の上面部40から垂下する第2の周壁41が外側に位置する外側壁となっている。そして、カバー部材8の第2の周壁41(外側壁)の内側に、支持体7の第1の周壁32(内側壁)を嵌合することで、カバー部材8と支持体7との間に緩衝室60が形成されている。この第3実施形態では、カバー部材8は、第2の周壁41(外側壁)の下端部に係止爪80をさらに備えている。一方で、支持体7の底面部30には、係止爪80と係合可能な係合段部70が設けられており、係止爪80と係合段部70とを緩衝室60の外側で相互に係合させることで、カバー部材8が支持体7に固定されている。
In the third embodiment, the first peripheral wall 32 erected on the bottom surface portion 30 of the support 7 is an inner side wall positioned inside, and the second peripheral wall 41 depending from the upper surface portion 40 of the cover member 8 is an outer side. The outer wall is located at Then, the first peripheral wall 32 (inner wall) of the support body 7 is fitted inside the second peripheral wall 41 (outer wall) of the cover member 8, so that the cover member 8 and the support body 7 are interposed. A buffer chamber 60 is formed. In the third embodiment, the cover member 8 further includes a locking claw 80 at the lower end portion of the second peripheral wall 41 (outer wall). On the other hand, the bottom surface portion 30 of the support body 7 is provided with an engaging step portion 70 that can be engaged with the locking claw 80, and the locking claw 80 and the engaging step portion 70 are connected to the outside of the buffer chamber 60. The cover member 8 is fixed to the support 7 by engaging with each other.
支持体7の第1の周壁32(内側壁)の上端部には、凹状に切り欠かれることで貫通穴67が形成されている。一方、カバー部材8の第2の周壁41(外側壁)の上端部にも貫通穴68が形成されている。貫通穴67,68はともに対応する位置に形成されており、カバー部材8が支持体7に装着されて、貫通穴67,68が一致することで、緩衝室60の側壁(内側壁および外側壁)に水平方向を向く空気流通孔62が形成されている。なお、空気流通孔62が水平方向よりも下向き(斜め下向き)になるように、貫通穴67,68を形成してもよい。
A through hole 67 is formed in the upper end portion of the first peripheral wall 32 (inner wall) of the support 7 by being cut out in a concave shape. On the other hand, a through hole 68 is also formed in the upper end portion of the second peripheral wall 41 (outer wall) of the cover member 8. The through holes 67 and 68 are both formed at corresponding positions, and the cover member 8 is mounted on the support 7 and the through holes 67 and 68 are aligned so that the side walls (inner and outer walls) of the buffer chamber 60 are aligned. ) Is formed with an air circulation hole 62 facing in the horizontal direction. Note that the through holes 67 and 68 may be formed so that the air circulation holes 62 are directed downward (obliquely downward) from the horizontal direction.
この第3実施形態においても、空気流通孔62は、緩衝室60の上部を覆う上壁ではなく、緩衝室60の側壁に、水平方向または水平方向よりも下向きを向くように設けられているので、薬液容器と支持体7との嵌合部分から薬液容器の下端面を伝って上方から支持体7内に水が浸入してきても、空気流通孔62から緩衝室60内に当該水が浸入することを防止できる。よって、緩衝室60内に貯留された薬液が薄められることを防止できる。
Also in the third embodiment, the air circulation hole 62 is provided not on the upper wall covering the upper portion of the buffer chamber 60 but on the side wall of the buffer chamber 60 so as to face the horizontal direction or downward in the horizontal direction. Even if water enters the support body 7 from above through the lower end surface of the chemical liquid container from the fitting portion between the chemical liquid container and the support body 7, the water enters the buffer chamber 60 from the air circulation hole 62. Can be prevented. Therefore, it is possible to prevent the chemical solution stored in the buffer chamber 60 from being diluted.
また、空気流通孔62は、緩衝室60の側壁の上端部に設けられているため、フラッシュ時に給水受皿に供給された水が下方から支持体7内へ浸入した場合でも、水は側壁を乗り超えて空気流通孔62に到達し難く、その結果、空気流通孔62から緩衝室60内に浸入するのが防止される。よって、緩衝室60内に貯留された薬液が薄められることを防止できる。
Further, since the air circulation hole 62 is provided at the upper end portion of the side wall of the buffer chamber 60, even when the water supplied to the water supply tray during the flushing enters the support body 7 from below, the water gets on the side wall. As a result, it is difficult to reach the air circulation hole 62 and as a result, the air circulation hole 62 is prevented from entering the buffer chamber 60. Therefore, it is possible to prevent the chemical solution stored in the buffer chamber 60 from being diluted.
なお、カバー部材8に、上記した第1実施形態の囲繞壁43と同じように、空気流通孔62の上方を覆う庇部材を設けるようにしてもよい。これにより、薬液容器と支持体7との嵌合部分から薬液容器の下端面を伝って上方から支持体7内に浸入する水が空気流通孔62に到達するのを確実に阻止することができる。
