排水構造Drainage structure

本揭露係關於一種排水構造。This disclosure relates to a drainage structure.

日本特開2019-44522號公報揭示一種在使用於洗衣機等用水機器的設置場所之防水盤設有排水捕集器的構造。此構造中，來自用水機器的軟管係與排水捕集器的水封容器連接(第一流道)。另外，預防此軟管破裂的情形，會設有與第一流道不同而貫通蓋體來連通於水封容器的第二流道。Japanese Patent Application Laid-Open No. 2019-44522 discloses a structure in which a drainage trap is provided on a waterproof pan used in the installation place of a water appliance such as a washing machine. In this structure, the hose from the water machine is connected to the water-sealed container of the drain trap (first flow path). In addition, to prevent this hose from rupturing, a second flow channel that penetrates the lid and communicates with the water-sealed container is different from the first flow channel.

然而，在虹吸排水系統中，即使排水流入此種第二流道，由於水頭較低因此從排水捕集器將排水往水平管推壓流動的力量會較弱。另一方面，在水平管開始發生虹吸力前需要一定的時間，在此之前會無法使排水多量地流動。由於上述原因，會有空氣變成累積在流道內而導致未進入第二流道之排水在防水盤上溢出之虞。作為其對策雖然考量了使水頭變高，但單純使水頭變高則會視地板下之高度方向而需要較大的空間。However, in a siphon drainage system, even if the drainage flows into such a second flow channel, the force of pushing the drainage from the drainage trap to the horizontal pipe will be weak due to the low water head. On the other hand, it takes a certain amount of time before the horizontal pipe starts to generate siphoning force, and before that, it is impossible to make a large amount of drainage flow. Due to the above-mentioned reasons, air may become accumulated in the flow channel and the drain water that has not entered the second flow channel may overflow on the waterproof pan. As a countermeasure, increasing the water head is considered, but simply increasing the water head will require a larger space depending on the height direction under the floor.

本揭露之目的在於抑制排水捕集器之高度並同時使已通過排水捕集器之水封的排水往虹吸排水管順暢地流動。The purpose of this disclosure is to suppress the height of the drainage trap and at the same time allow the drainage that has passed through the water seal of the drainage trap to flow smoothly to the siphon drainage pipe.

第1態樣之排水構造，係具有：排水捕集器，係構成為可儲藏水封，且是使上部***於設在板狀構件的貫通部來加以設置；虹吸排水管，係連接在較該排水捕集器的該水封要下游側；以及通氣管，係連接在較該排水捕集器的該水封要下游側之中較該虹吸排水管要上方且包含該排水捕集器的該上部之位置。The drainage structure of the first aspect has: a drainage trap, which is configured to store a water seal, and is installed by inserting the upper part into a through part provided in a plate-shaped member; and a siphon drainage pipe, which is connected to the The water seal of the drainage trap is on the downstream side; and the vent pipe is connected to the downstream side of the water seal of the drainage trap, which is above the siphon drainage pipe and contains the drainage trap. The position of the upper part.

此排水構造中，排水捕集器的上部係***於設在板狀構件的貫通部，且通氣管係連接於包含該上部之位置。藉此，可抑制通氣管與板狀構件之干擾且同時使通氣管連接在排水捕集器的較高位置。另外，藉此，通氣管與虹吸排水管的上下方向距離會變大，因此可抑制排水捕集器與通氣管的連接位置被已通過水封的排水所堵塞之情形。因此，能使較排水捕集器內之水封要下游側的空氣往通氣管流動，而抑制該空氣滯留在排水捕集器內之情形。另外，藉由使通氣管與虹吸排水管的上下方向距離變大，水頭也會變大，因此能使已通過水封的排水容易往虹吸排水管順暢地流動。In this drainage structure, the upper part of the drainage trap is inserted into the through part provided in the plate-shaped member, and the vent pipe is connected to a position including the upper part. Thereby, the interference between the vent pipe and the plate-shaped member can be suppressed, and at the same time, the vent pipe can be connected to a higher position of the drainage trap. In addition, due to this, the vertical distance between the vent pipe and the siphon drain pipe is increased, so that the connection position of the drainage trap and the vent pipe can be prevented from being blocked by the drain that has passed the water seal. Therefore, the air on the downstream side of the water seal in the drainage trap can be made to flow to the vent pipe, and the situation that the air stays in the drainage trap can be suppressed. In addition, by increasing the vertical distance between the vent pipe and the siphon drain pipe, the water head will also increase, so that the drain that has passed through the water seal can easily flow to the siphon drain pipe smoothly.

第2態樣，係在第1態樣之排水構造中，該排水捕集器係具有連接有該虹吸排水管及該通氣管的外筐、配置在該外筐內側且可儲藏該水封的內筐、及配置在該內筐內側且形成該水封的內筒；該虹吸排水管之內周面下端係位於該外筐底部之高度。In the second aspect, in the drainage structure of the first aspect, the drainage trap has an outer basket connected with the siphon drain pipe and the vent pipe, and is arranged inside the outer basket and can store the water seal The inner basket and the inner cylinder arranged inside the inner basket and forming the water seal; the lower end of the inner peripheral surface of the siphon drain pipe is located at the height of the bottom of the outer basket.

此排水構造中，藉由使虹吸排水管之內周面下端與外筐底部之高度一致，便可進一步地抑制排水捕集器之高度。In this drainage structure, the height of the lower end of the inner peripheral surface of the siphon drainage pipe and the bottom of the outer basket can be aligned, so that the height of the drainage trap can be further suppressed.

第3態樣，係在第1態樣或第2態樣之排水構造中，該通氣管與該虹吸排水管係藉由連通管來加以連接。In the third aspect, in the drainage structure of the first aspect or the second aspect, the vent pipe and the siphon drainage pipe are connected by a connecting pipe.

此排水構造中，即使排水流入通氣管之情形，該排水也會通過連通管往虹吸排水管排出。因此，便可進行通氣管之除水。In this drainage structure, even if the drainage flows into the vent pipe, the drainage will be discharged to the siphon drainage pipe through the connecting pipe. Therefore, water removal of the vent pipe can be performed.

第4態樣，係在第3態樣之排水構造中，在該連通管之內部設有浮閥，係在該通氣管與該虹吸排水管之間會使管內的空氣往雙向流通，且會使排水從該通氣管往該虹吸排水管流通，而不會使排水從該虹吸排水管往該通氣管流通。In the fourth aspect, in the drainage structure of the third aspect, a float valve is provided inside the communicating pipe, and the air in the pipe can circulate in both directions between the vent pipe and the siphon drain pipe, and The drainage is caused to circulate from the vent pipe to the siphon drainage pipe, and the drainage is not caused to circulate from the siphon drainage pipe to the vent pipe.

此排水構造中，由於在連通管之內部設有浮閥，因此能將空氣從連通於連通管之虹吸排水管往通氣管排出，且能抑制排水從連通於連通管之虹吸排水管往通氣管流入。In this drainage structure, since a float valve is provided inside the communicating pipe, air can be discharged from the siphon drain pipe connected to the communicating pipe to the vent pipe, and drainage can be suppressed from the siphon drain pipe connected to the communicating pipe to the vent pipe Inflow.

第5態樣，係在第3態樣或第4態樣之排水構造中，該通氣管係具有位於從該通氣管與該排水捕集器之連接部往下方延伸的部分與再次朝向上方之部分的邊界之較低部分；該連通管係連接於該通氣管之該較低部分。The fifth aspect is in the drainage structure of the third aspect or the fourth aspect, and the vent pipe has a part extending downward from the connection part of the vent pipe and the drainage trap and a part that is again facing upward. The lower part of the boundary of the part; the communication pipe is connected to the lower part of the vent pipe.

此排水構造中，由於連通管係連接於通氣管之較低部分，因此即使排水流入通氣管之情形，該排水也會容易通過連通管而往虹吸排水管排出。因此，可有效率地進行通氣管之排水。In this drainage structure, since the communicating pipe is connected to the lower part of the vent pipe, even if the drain water flows into the vent pipe, the drain can easily be discharged to the siphon drain pipe through the communicating pipe. Therefore, drainage of the vent pipe can be efficiently performed.

第6態樣，係在第5態樣之排水構造中，該板狀構件係地板材；在該地板材之上設有防水盤；該排水捕集器係連接於該防水盤；在俯視時，該通氣管之該較低部分會與該貫通部重疊。The sixth aspect is in the drainage structure of the fifth aspect, the plate-shaped member is a floor plate; a waterproof pan is arranged on the floor plate; the drainage trap is connected to the waterproof pan; when viewed from above , The lower part of the vent pipe will overlap with the through part.

此排水構造中，由於排水捕集器係連接於防水盤；在俯視時，通氣管之較低部分會與貫通部重疊，故連接於該較低部分之連通管會位於排水捕集器附近。因此，能容易從排水捕集器一側來進行易於附著污垢之連通管的清掃。In this drainage structure, since the drainage trap is connected to the waterproof pan; when viewed from above, the lower part of the vent pipe overlaps the through part, so the connecting pipe connected to the lower part is located near the drainage trap. Therefore, it is possible to easily clean the communicating pipe where dirt is likely to adhere from the side of the drainage trap.

根據本揭露的排水構造，便可抑制排水捕集器之高度並同時使已通過排水捕集器之水封的排水往虹吸排水管順暢地流動。According to the drainage structure of the present disclosure, the height of the drainage trap can be suppressed and at the same time, the drainage that has passed through the water seal of the drainage trap can flow smoothly to the siphon drainage pipe.

以下，根據圖式來說明用以實施本揭露的形態。各圖中使用相同符號所示的構成要素係意指相同之構成要素。此外，關於以下說明之實施形態中，重複之說明及符號會有省略之情形。Hereinafter, the mode for implementing the present disclosure will be described based on the drawings. The constituent elements shown with the same symbols in the respective figures mean the same constituent elements. In addition, in the embodiments described below, overlapping descriptions and symbols may be omitted.

[第1實施形態] 圖1中，本實施形態之排水構造10係具有排水捕集器12、作為虹吸排水管之一例的水平管14、及通氣管16。[First Embodiment] In Fig. 1, the drainage structure 10 of the present embodiment includes a drainage trap 12, a horizontal pipe 14 as an example of a siphon drainage pipe, and a vent pipe 16.

在建築物17之樓板18上方水平設有作為板狀構件之一例的地板材22。在地板材22與樓板18之間設有地板下空間24。在地板材22上設有防水盤26。在防水盤26上設置有未圖示的洗衣機等之用水機器。用水機器與排水捕集器12係藉由例如軟管28來加以連接。藉由使用防水盤26，即使在軟管28破裂而導致排水洩漏之情形，亦能以該防水盤26來承接該排水並使其往排水捕集器12流動。在地板材22形成有貫通部32。排水捕集器12會通過此貫通部32而連接於防水盤26。A floor plate 22 as an example of a plate-shaped member is horizontally provided above the floor 18 of the building 17. An under-floor space 24 is provided between the floor slab 22 and the floor 18. A waterproof pan 26 is provided on the floor material 22. Water equipment such as a washing machine (not shown) is installed on the waterproof pan 26. The water machine and the drainage trap 12 are connected by a hose 28, for example. By using the waterproof pan 26, even if the hose 28 ruptures and the drainage leaks, the waterproof pan 26 can receive the drainage and make it flow to the drainage trap 12. A penetration portion 32 is formed in the floor material 22. The drain trap 12 is connected to the waterproof pan 26 through this through portion 32.

排水捕集器12係構成為可儲藏水封34。此排水捕集器12是使上部41A***於設在地板材22的貫通部32來加以設置。具體而言，排水捕集器12係具有外筐41、內筐42、及內筒43。上部41A，係在排水捕集器12之上端連接在防水盤26時位於該排水捕集器12之中與地板材22在水平方向重疊之位置的部位。The drainage trap 12 is configured to store a water seal 34. This drain trap 12 is installed by inserting the upper part 41A into the penetration part 32 provided in the floor material 22. As shown in FIG. Specifically, the drainage trap 12 has an outer basket 41, an inner basket 42, and an inner tube 43. The upper part 41A is a part at the position where the upper end of the drainage trap 12 is connected to the waterproof pan 26 and which overlaps the floor plate 22 in the horizontal direction.

外筐41係排水捕集器12之中連接有水平管14與通氣管16的最外側容器。外筐41之上部41A係***於地板材22之貫通部32。外筐41係抵接於防水盤26的下面。在防水盤26的上面一側配置有環狀之安裝構件36。在安裝構件36與防水盤26之間設有襯墊38。安裝構件36可螺合於外筐41之螺紋部41B(參照圖6至圖8)，藉由使安裝構件36螺合於外筐41之螺紋部41B，防水盤26便會被水密地夾入於襯墊38與外筐41之間。藉此，外筐41便會被固定在防水盤26下面。The outer basket 41 is the outermost container of the drainage trap 12 to which the horizontal pipe 14 and the vent pipe 16 are connected. The upper part 41A of the outer basket 41 is inserted into the through part 32 of the floor material 22. The outer basket 41 abuts against the underside of the waterproof pan 26. A ring-shaped mounting member 36 is arranged on the upper surface side of the waterproof pan 26. A gasket 38 is provided between the mounting member 36 and the waterproof pan 26. The mounting member 36 can be screwed to the threaded portion 41B of the outer basket 41 (refer to FIGS. 6 to 8). By screwing the mounting member 36 to the threaded portion 41B of the outer basket 41, the waterproof plate 26 will be watertightly clamped Between the liner 38 and the outer basket 41. In this way, the outer basket 41 will be fixed under the waterproof pan 26.

內筐42係配置在外筐41內側且可儲藏水封34的容器。在內筐42之外周面貫通形成有決定水封34之水位上限的排水窗42A。內筐42係通過敞開的排水捕集器12之開口部(未圖示)而從防水盤26一側往外筐41內側拆裝自如。The inner basket 42 is a container that is arranged inside the outer basket 41 and can store the water seal 34. A drainage window 42A that determines the upper limit of the water level of the water seal 34 is formed through the outer peripheral surface of the inner basket 42. The inner basket 42 is detachably detachable from the waterproof pan 26 side to the inner side of the outer basket 41 through an opening (not shown) of the open drain trap 12.

內筒43係配置在內筐42之內側，係形成水封34的筒狀構件。此內筒43係通過在防水盤26敞開的排水捕集器12之開口部(未圖示)而從防水盤26一側往內筐42內側拆裝自如。在排水捕集器12中，來自用水機器之排水會流入內筒43內側而與水封34混合，且從內筐42之排水窗42A溢出的排水會進入外筐41內，接著通過水平管14而往排水捕集器12之外側排出。The inner tube 43 is a cylindrical member that is arranged inside the inner basket 42 and forms a water seal 34. The inner tube 43 is freely detachable from the side of the waterproof pan 26 to the inside of the inner basket 42 through an opening (not shown) of the drain trap 12 opened in the waterproof pan 26. In the drainage trap 12, the drainage from the water machine will flow into the inner cylinder 43 and mix with the water seal 34, and the drainage overflowing from the drainage window 42A of the inner basket 42 will enter the outer basket 41 and then pass through the horizontal pipe 14. And it is discharged to the outside of the drain trap 12.

水平管14係連接於較排水捕集器12之水封34要下游側。此水平管14係例如水平配置在樓板18上。排水捕集器12之外筐41之底部係位於樓板18之上面附近。其結果，水平管14之內周面下端便會位於外筐41底部之高度。在水平管14之下游端連接有往建築物17下方延伸之豎管(未圖示)。此豎管之下端係連接於貫通建築物17之各樓層的排水管(未圖示)。The horizontal pipe 14 is connected to the downstream side of the water seal 34 of the drainage trap 12. The horizontal pipe 14 is horizontally arranged on the floor 18, for example. The bottom of the outer basket 41 of the drain trap 12 is located near the upper surface of the floor 18. As a result, the lower end of the inner peripheral surface of the horizontal tube 14 will be located at the height of the bottom of the outer basket 41. A vertical pipe (not shown) extending below the building 17 is connected to the downstream end of the horizontal pipe 14. The lower end of the vertical pipe is connected to a drainage pipe (not shown) that passes through each floor of the building 17.

通氣管16係為了抑制虹吸力發生時水封34之破封而被設置。此通氣管16係連接在較排水捕集器12的水封34要下游側之中，較水平管14要上方且包含排水捕集器12的上部41A之位置。具體而言，通氣管16對於排水捕集器12的連接部16A係連接於排水捕集器12的外筐41之中，***於地板材22之貫通部32的上部41A。此外，通氣管16之連接部16A也可以跨越來連接於***於貫通部32的上部41A與未***於貫通部32的部分，換句話說即較地板材22要低之部分。連接部16A之上端係位於地板材22存在有厚度之範圍內。雖然連接部16A之下端也可以位於較地板材22要低之部分，但從盡量不使滯留在排水捕集器12的排水進入通氣管16之觀點來看，較佳係位於厚度之範圍內。The vent pipe 16 is provided in order to suppress the breaking of the water seal 34 when the siphon force occurs. The vent pipe 16 is connected to the downstream side of the water seal 34 of the drainage trap 12 and above the horizontal pipe 14 and includes the upper portion 41A of the drainage trap 12. Specifically, the connecting portion 16A of the vent pipe 16 to the drainage trap 12 is connected to the outer basket 41 of the drainage trap 12 and inserted into the upper portion 41A of the penetration portion 32 of the floor material 22. In addition, the connecting portion 16A of the vent pipe 16 may span to connect the upper portion 41A inserted into the through portion 32 and the portion not inserted into the through portion 32, in other words, a portion lower than the floor plate 22. The upper end of the connecting portion 16A is located within the range where the thickness of the floor plate 22 exists. Although the lower end of the connecting portion 16A can also be located at a lower portion than the floor plate 22, from the viewpoint of preventing the drain trapped in the drain trap 12 from entering the vent pipe 16 as much as possible, it is preferably located within the thickness range.

通氣管16係具有位於從與排水捕集器12之連接部16A往下方延伸的部分(亦即，下降部16B)與再次朝向上方之部分(亦即，主管部16C)的邊界之較低部分16D。在俯視時，通氣管16之較低部分16D會與貫通部32重疊。通氣管16之主管部16C係配置在地板下空間24之中，接近地板材22的高度。在主管部16C附設有從較低部分16D朝向上升部16E之上升梯度。其原因在於：在排水流入通氣管16之情形，為了抑制該排水流向通氣管16之下游側。在通氣管16之主管部16C的下游側端部設有例如往上方延伸之上升部16E。上升部16E係通過設在地板材22之貫通部40與相鄰壁44之間而往上方延伸。The vent pipe 16 has a lower portion located at the boundary between a portion extending downward from the connection portion 16A with the drainage trap 12 (ie, the descending portion 16B) and the portion that faces upward again (ie, the main pipe portion 16C) 16D. When viewed from above, the lower portion 16D of the vent pipe 16 overlaps with the through portion 32. The main part 16C of the vent pipe 16 is arranged in the under-floor space 24 close to the height of the floor plate 22. The main pipe part 16C is provided with an ascending gradient from the lower part 16D to the ascending part 16E. The reason for this is to prevent the drainage from flowing to the downstream side of the vent pipe 16 when the drain water flows into the vent pipe 16. At the downstream end of the main pipe portion 16C of the vent pipe 16, for example, a rising portion 16E extending upward is provided. The rising portion 16E is provided between the through portion 40 of the floor material 22 and the adjacent wall 44 to extend upward.

此外，作為一例，通氣管16係在上升部16E延伸至洗衣機等之用水機器的高度後，再次下降並進入地板下空間24，並連接於例如排水管(未圖示)。In addition, as an example, the vent pipe 16 is extended to the height of a water appliance such as a washing machine after the rising portion 16E is lowered again and enters the underfloor space 24, and is connected to, for example, a drain pipe (not shown).

通氣管16與水平管14係藉由例如延伸於上下方向之連通管50來加以連接。連通管50係連接於通氣管16之較低部分16D。在俯視時，通氣管16之較低部分16D會與貫通部32重疊，因此連接於該較低部分16D之連通管50的上端部也會位於與貫通部32重疊的位置。The vent pipe 16 and the horizontal pipe 14 are connected by, for example, a communication pipe 50 extending in the up and down direction. The connecting pipe 50 is connected to the lower part 16D of the vent pipe 16. In a plan view, the lower portion 16D of the vent pipe 16 overlaps the through portion 32, so the upper end of the communication pipe 50 connected to the lower portion 16D is also located at a position overlapping with the through portion 32.

在連通管50之內部設有浮閥52(參照圖2)。浮閥52係構成為在通氣管16與水平管14之間會使管內的空氣往雙向流通，且會使排水從通氣管16往水平管14流通，而不會使排水從水平管14往通氣管16流通。具體而言，如圖2所示，在連通管50之內部設有浮球46。浮球46之密度較空氣之密度要大且較水之密度要小。因此，浮球46相對於水會浮起且相對於空氣會下降。在浮球46下側設有支撐部48，係用以使浮球46不會往連通管50下方脫離。即使是浮球46載置在支撐部48之狀態下，也會在浮球46與支撐部48周圍之間確保間隙。因此，能在通氣管16與水平管14之間使管內的空氣往雙向流通，或使排水從通氣管16往水平管14流通。另一方面，在浮球46上側設有閥座54。藉由從水平管14流入連通管50之排水而使浮球46抵接於閥座54時，連通管50與通氣管16之間便會被閉塞，而不會使排水從水平管14往通氣管16流通。A float valve 52 is provided in the communication pipe 50 (refer to FIG. 2). The float valve 52 is configured to allow the air in the pipe to circulate bidirectionally between the vent pipe 16 and the horizontal pipe 14, and to circulate the drainage from the vent pipe 16 to the horizontal pipe 14, without causing the drainage to flow from the horizontal pipe 14. The vent pipe 16 circulates. Specifically, as shown in FIG. 2, a float 46 is provided inside the communication pipe 50. The density of the float 46 is greater than that of air and less than that of water. Therefore, the float 46 will float with respect to the water and will drop with respect to the air. A supporting portion 48 is provided on the lower side of the floating ball 46 to prevent the floating ball 46 from escaping below the communicating pipe 50. Even in the state where the floating ball 46 is placed on the supporting portion 48, a gap is secured between the floating ball 46 and the periphery of the supporting portion 48. Therefore, it is possible to circulate the air in the pipe bidirectionally between the vent pipe 16 and the horizontal pipe 14, or to circulate the drainage from the vent pipe 16 to the horizontal pipe 14. On the other hand, a valve seat 54 is provided on the upper side of the float 46. When the floating ball 46 abuts against the valve seat 54 by the drainage flowing from the horizontal pipe 14 into the communicating pipe 50, the connection between the communicating pipe 50 and the vent pipe 16 will be blocked, and the drainage will not pass through the horizontal pipe 14. The trachea 16 circulates.

(作用) 本實施形態係如上述般構成，以下說明其作用。圖1中，排水構造10係使排水捕集器12的上部41A***於設在地板材22的貫通部32，且通氣管16係連接於包含該上部41A之位置。藉此，可抑制通氣管16與地板材22之干擾且同時使通氣管16連接在排水捕集器12的較高位置。另外，藉此，通氣管16與水平管14的上下方向距離會變大，因此可抑制排水捕集器12與通氣管16的連接位置被已通過水封34的排水所堵塞之情形。因此，能使較排水捕集器12內之水封34要下游側的空氣往通氣管16流動，而抑制該空氣滯留在排水捕集器12內之情形。另外，藉由使通氣管16與水平管14的上下方向距離變大，水頭也會變大，因此能使已通過水封34的排水容易往水平管14順暢地流動。(effect) The present embodiment is configured as described above, and its effect will be described below. In FIG. 1, in the drainage structure 10, the upper portion 41A of the drainage trap 12 is inserted into the through portion 32 provided on the floor plate 22, and the vent pipe 16 is connected to a position including the upper portion 41A. Thereby, the interference between the vent pipe 16 and the floor 22 can be suppressed, and the vent pipe 16 can be connected to the higher position of the drainage trap 12 at the same time. In addition, as a result, the vertical distance between the vent pipe 16 and the horizontal pipe 14 is increased, so that the connection position between the drain trap 12 and the vent pipe 16 is prevented from being blocked by the drain water that has passed through the water seal 34. Therefore, the air on the downstream side of the water seal 34 in the drainage trap 12 can be caused to flow toward the vent pipe 16, and the situation in which the air stays in the drainage trap 12 can be suppressed. In addition, by increasing the vertical distance between the vent pipe 16 and the horizontal pipe 14, the water head also increases. Therefore, the drainage that has passed through the water seal 34 can easily flow to the horizontal pipe 14 smoothly.

另外，藉由使水平管14之內周面下端與外筐41底部之高度一致，可進一步抑制排水捕集器12之高度。In addition, by aligning the lower end of the inner peripheral surface of the horizontal pipe 14 with the height of the bottom of the outer basket 41, the height of the drain trap 12 can be further suppressed.

再者，由於通氣管16與水平管14係藉由連通管50來加以連接，故即使排水流入通氣管16之情形，該排水也會通過連通管50往水平管14排出。因此，可進行通氣管16之除水。Furthermore, since the vent pipe 16 and the horizontal pipe 14 are connected by the communicating pipe 50, even if the drain water flows into the vent pipe 16, the drain will be discharged to the horizontal pipe 14 through the communicating pipe 50. Therefore, the vent pipe 16 can be dewatered.

另外，由於在連通管50之內部設有浮閥52，因此能將空氣從連通於連通管50之水平管14往通氣管16排出，且能抑制排水從連通於連通管50之水平管14往通氣管16流入。In addition, since the float valve 52 is provided inside the communicating pipe 50, air can be discharged from the horizontal pipe 14 connected to the communicating pipe 50 to the vent pipe 16, and drainage from the horizontal pipe 14 connected to the communicating pipe 50 can be suppressed. The vent pipe 16 flows in.

再者，由於連通管50係連接於通氣管16之較低部分16D，因此即使排水流入通氣管16之情形，該排水也會容易通過連通管50而往水平管14排出。具體而言，從通氣管16之連接部16A流入至下降部16B之排水與流入至主管部16C之排水皆會匯集在較低部分16D，並通過連通管50往水平管14排出。因此，可有效率地進行通氣管16之除水。Furthermore, since the communicating pipe 50 is connected to the lower portion 16D of the vent pipe 16, even if the drainage flows into the vent pipe 16, the drainage is easily discharged to the horizontal pipe 14 through the communicating pipe 50. Specifically, the drainage flowing from the connecting portion 16A of the vent pipe 16 to the descending portion 16B and the drainage flowing into the main pipe portion 16C are collected in the lower portion 16D and discharged to the horizontal pipe 14 through the communicating pipe 50. Therefore, the water removal of the vent pipe 16 can be performed efficiently.

另外，由於排水捕集器12係連接於防水盤26，在俯視時，通氣管16之較低部分16D會與地板材22之貫通部32重疊，因此連接於該較低部分16D之連通管50會位於排水捕集器12附近。因此，能容易從排水捕集器12一側來進行容易附著污垢之連通管50的清掃。In addition, since the drainage trap 12 is connected to the waterproof pan 26, when viewed from above, the lower part 16D of the vent pipe 16 overlaps with the through part 32 of the floor plate 22, so it is connected to the connecting pipe 50 of the lower part 16D. It will be located near the drain trap 12. Therefore, it is possible to easily clean the communication pipe 50 to which dirt easily adheres from the side of the drainage trap 12.

如上述，根據本實施形態，可抑制排水捕集器12之高度並同時使已通過排水捕集器12之水封34的排水往水平管14(虹吸排水管)順暢地流動。As described above, according to this embodiment, the height of the drainage trap 12 can be suppressed, and the drainage that has passed through the water seal 34 of the drainage trap 12 can flow smoothly to the horizontal pipe 14 (siphon drainage pipe).

[第2實施形態] 圖3中，本實施形態之排水構造20中，係在防水盤26之設置範圍內，在地板材22設有在貫通部32敞開之缺口60。通氣管16係通過缺口60而連接於包含排水捕集器12之上部41A的位置。具體而言，通氣管16對於排水捕集器12的連接部16A係連接於排水捕集器12的外筐41之中，被***於地板材22之貫通部32的上部41A。此外，通氣管16之連接部16A也可以跨越來連接於***於貫通部32的上部41A與未***於貫通部32的部分、換句話說即較地板材22要低之部分。[Second Embodiment] In FIG. 3, in the drainage structure 20 of this embodiment, within the installation range of the waterproof pan 26, the floor 22 is provided with a notch 60 that opens at the through portion 32. The vent pipe 16 is connected to a position including the upper portion 41A of the drainage trap 12 through the notch 60. Specifically, the connecting portion 16A of the vent pipe 16 to the drainage trap 12 is connected to the outer basket 41 of the drainage trap 12 and inserted into the upper portion 41A of the penetration portion 32 of the floor material 22. In addition, the connecting portion 16A of the vent pipe 16 may span to connect the upper portion 41A inserted into the through portion 32 and a portion not inserted into the through portion 32, in other words, a portion lower than the floor plate 22.

圖3中，缺口60係具有從下面側去除地板材22之部分的形狀。由於地板材22之上面側也包含缺口60之部分且為平坦，因此適於支撐防水盤26。另外，缺口60係具有使地板材22變薄的平坦部60A及傾斜部60C。傾斜部60C係將平坦部60A與沒有缺口60的一般部60B加以連接的部位。在傾斜部60C中，地板材22之厚度會變化。此外，圖3所示之範例中，缺口60雖然在上下方向未貫通地板材22，但也可以構成為在上下方向貫通地板材22。In FIG. 3, the notch 60 has a shape in which a part of the floor board 22 is removed from the lower surface side. Since the upper side of the floor material 22 also includes the part of the notch 60 and is flat, it is suitable for supporting the waterproof pan 26. In addition, the notch 60 has a flat portion 60A and an inclined portion 60C that thin the floor material 22. The inclined portion 60C is a portion that connects the flat portion 60A and the general portion 60B without the notch 60. In the inclined portion 60C, the thickness of the floor material 22 changes. In addition, in the example shown in FIG. 3, although the notch 60 does not penetrate the floor material 22 in the up-down direction, it may be configured to penetrate the floor board 22 in the up-down direction.

通氣管16之下降部16B係沿著缺口60之傾斜部60C來加以配置。通氣管16係從連接部16A水平配置至下降部16B之前。此外，也可以對於此區間來朝向下降部16B一側附加下降梯度。另外，主管部16C係配置在接近地板材22之高度，且水平配置成到達上升部16E。此外，也可以對於此區間來朝向上升部16E一側附加下降梯度。The descending portion 16B of the vent pipe 16 is arranged along the inclined portion 60C of the notch 60. The vent pipe 16 is horizontally arranged from the connecting portion 16A to before the descending portion 16B. In addition, a descending gradient may be added to the descending portion 16B side for this interval. Moreover, the main pipe part 16C is arrange|positioned at the height close to the floor material 22, and is arrange|positioned horizontally so that it may reach the rising part 16E. In addition, it is also possible to add a descending gradient toward the ascending portion 16E side for this section.

通氣管16之較低部分16D係設在沒有缺口60之部分且連接於連通管50。換句話說，通氣管16之較低部分16D係設在從缺口60偏離之位置，也就是從排水捕集器12離開之位置。圖3中，通氣管16之較低部分16D係設在上升部16E之正下方。連通管50也是設在上升部16E之正下方。在連通管50之內部設有與第1實施形態相同之浮閥52(參照圖2)。The lower part 16D of the vent pipe 16 is provided in the part without the notch 60 and connected to the connecting pipe 50. In other words, the lower part 16D of the vent pipe 16 is set at a position deviated from the notch 60, that is, a position away from the drain trap 12. In FIG. 3, the lower portion 16D of the vent pipe 16 is provided directly below the rising portion 16E. The connecting pipe 50 is also provided directly below the rising portion 16E. Inside the communication pipe 50, a float valve 52 (refer to FIG. 2) similar to that of the first embodiment is provided.

關於其他部分係與第1實施形態相同，因此在圖式中會對相同部分賦予相同符號以省略說明。The other parts are the same as those in the first embodiment, and therefore the same parts are given the same reference numerals in the drawings to omit the description.

(作用) 本實施形態係如上述般構成，以下說明其作用。圖3中，排水構造20係使通氣管16通過設在地板材22之缺口60而連接於包含排水捕集器12之中，被***於地板材22的貫通部32之上部41A的位置。因此，可抑制通氣管16與地板材22之干擾。(effect) The present embodiment is configured as described above, and its effect will be described below. In FIG. 3, in the drainage structure 20, the vent pipe 16 is connected to the drainage trap 12 including the drainage trap 12 through the notch 60 provided in the floor material 22, and is inserted into the position of the upper portion 41A of the penetration portion 32 of the floor material 22. Therefore, the interference between the vent pipe 16 and the floor 22 can be suppressed.

另外，通氣管16之較低部分16D係設在沒有缺口60之部分且連接於連通管50。亦即，與通氣管16之較低部分16D和地板材22之貫通部32重疊的情形相較，從排水捕集器12至連通管50的距離會較長。因此，會在某種程度上容許排水流入通氣管16之情形。In addition, the lower portion 16D of the vent pipe 16 is provided at the portion without the notch 60 and connected to the communication pipe 50. That is, compared with the case where the lower portion 16D of the vent pipe 16 and the through portion 32 of the floor plate 22 overlap, the distance from the drainage trap 12 to the communication pipe 50 is longer. Therefore, a situation in which the drain water flows into the vent pipe 16 is allowed to some extent.

[參考例] 圖4中，參考例之排水構造30中，係在排水捕集器12之外筐41內部形成有與通氣管16連通且朝向上方延伸至地板材22之高度位置的通氣道70。作為一例，通氣道70係形成在外筐41之內面與從內面分離的第1壁部71之間。另外，通氣道70係從外筐41中通氣管16的連接位置41C之內側往上方延伸。通氣道70與外筐41中水平管14的連接位置41D之內側部56係藉由連通道58來加以連接。連通道58係形成在外筐41之內面與從內面分離的第2壁部72之間。[Reference example] In FIG. 4, in the drainage structure 30 of the reference example, a vent 70 communicating with the vent pipe 16 and extending upward to the height of the floor 22 is formed inside the outer basket 41 of the drainage trap 12. As an example, the air passage 70 is formed between the inner surface of the outer basket 41 and the first wall portion 71 separated from the inner surface. In addition, the air passage 70 extends upward from the inside of the connection position 41C of the air pipe 16 in the outer basket 41. The air passage 70 and the inner side 56 of the connecting position 41D of the horizontal tube 14 in the outer basket 41 are connected by a connecting channel 58. The connecting passage 58 is formed between the inner surface of the outer basket 41 and the second wall 72 separated from the inner surface.

在外筐41之徑向上，通氣道70之寬度會較連通道58之寬度要小。第1壁部71與第2壁部72係藉由相對於外筐41之上下方向而傾斜的傾斜壁部73來結合而加以連接。第1壁部71、傾斜壁部73及第2壁部72係作為例如壁形成構件74而一體形成。此壁形成構件74可從外筐41移除。In the radial direction of the outer basket 41, the width of the air passage 70 is smaller than the width of the connecting passage 58. The first wall portion 71 and the second wall portion 72 are coupled by an inclined wall portion 73 that is inclined with respect to the upper and lower direction of the outer basket 41 to be connected. The first wall portion 71, the inclined wall portion 73, and the second wall portion 72 are integrally formed as, for example, the wall forming member 74. This wall forming member 74 can be removed from the outer basket 41.

如圖8所示，在外筐41之內面設有往上下方向延伸之例如剖面L字形的導軌76。此導軌76係設有一對。另外，如圖9所示，在壁形成構件74係設有會沿著導軌76滑動且嵌合於該導軌76的嵌合部78。藉由使嵌合部78沿著導軌76往上下方向滑動，壁形成構件74便可相對於外筐41拆裝。As shown in FIG. 8, the inner surface of the outer basket 41 is provided with a guide rail 76 having an L-shaped cross-section extending in the vertical direction. The guide rail 76 is provided with a pair. In addition, as shown in FIG. 9, the wall forming member 74 is provided with a fitting portion 78 that slides along the guide rail 76 and is fitted to the guide rail 76. By sliding the fitting portion 78 in the vertical direction along the guide rail 76, the wall forming member 74 can be detached from the outer basket 41.

此外，壁形成構件74相對於外筐41之安裝方向並不限於上下方向，也可為徑向。作為一例，也可以為在外筐41之內面設置往徑向內側突出之鉤部(未圖示)，且使壁形成構件74的嵌合部78嵌入於該鉤部之構成。此情形，壁形成構件74便可相對於外筐41在徑向上拆裝。此外，鉤部也可以形成為剖面箭頭狀或單箭頭狀。另外，壁形成構件74的材質也可以為矽氧橡膠等之彈性材料。In addition, the mounting direction of the wall forming member 74 with respect to the outer basket 41 is not limited to the vertical direction, and may be the radial direction. As an example, a hook portion (not shown) protruding radially inward is provided on the inner surface of the outer basket 41, and the fitting portion 78 of the wall forming member 74 is fitted into the hook portion. In this case, the wall forming member 74 can be detached and detached relative to the outer basket 41 in the radial direction. In addition, the hook portion may be formed in a cross-sectional arrow shape or a single arrow shape. In addition, the material of the wall forming member 74 may also be an elastic material such as silicone rubber.

如圖5至圖7所示，在通氣道70之上端係設有遮蔽通氣道70往上方敞開的凸緣64。如圖8、圖9所示，凸緣64係例如透過多個支撐部67而一體形成在第1壁部71之上端。藉由此凸緣64，通氣道70會往外筐41之徑向內側敞開。As shown in FIGS. 5 to 7, a flange 64 that shields the air duct 70 from opening upward is provided at the upper end of the air duct 70. As shown in FIGS. 8 and 9, the flange 64 is integrally formed on the upper end of the first wall portion 71 through, for example, a plurality of support portions 67. With this flange 64, the air passage 70 will open to the radially inner side of the outer basket 41.

圖4、圖5中，在連通道58之內部係設有浮閥62。此浮閥62係構成為會在通氣道70與內側部56之間使管內的空氣往雙向流通，且會使排水從通氣道70往內側部56流通，而不會使排水從內側部56往通氣道70流通。具體而言，在連通道58之內部設有浮球66。浮球66之密度會較空氣之密度要大且較水之密度要小。因此，浮球66相對於排水會浮起且相對於空氣會下降。在浮球66下側設有支撐部68，係用以使浮球66不會往連通道58下方脫離。即使是浮球66載置在支撐部68之狀態下，仍可在浮球66與支撐部68周圍之間確保間隙。因此，能在通氣道70與內側部56之間使管內的空氣往雙向流通，或使排水從通氣道70往內側部56流通。另一方面，在浮球66上側設有閥座84。藉由從內側部56流入連通道58之排水而使浮球66抵接於閥座84時，連通道58與通氣道70之間會被閉塞，而不會使排水從內側部56往通氣道70流通。In Figs. 4 and 5, a float valve 62 is provided inside the connecting passage 58. As shown in Figs. The float valve 62 is configured to allow the air in the pipe to circulate bidirectionally between the air passage 70 and the inner part 56 and to circulate the drain from the air passage 70 to the inner part 56 without causing the drain to pass from the inner part 56. Circulate to the airway 70. Specifically, a floating ball 66 is provided inside the communication channel 58. The density of the float 66 will be greater than that of air and less than that of water. Therefore, the float 66 will float with respect to the drainage and will drop with respect to the air. A supporting portion 68 is provided on the lower side of the floating ball 66 to prevent the floating ball 66 from escaping below the connecting channel 58. Even in the state where the floating ball 66 is placed on the support portion 68, a gap can be secured between the floating ball 66 and the periphery of the support portion 68. Therefore, it is possible to circulate the air in the tube bidirectionally between the air passage 70 and the inner portion 56 or to circulate the drain water from the air passage 70 to the inner portion 56. On the other hand, a valve seat 84 is provided on the upper side of the float ball 66. When the floating ball 66 abuts against the valve seat 84 by the drainage flowing into the connecting passage 58 from the inner portion 56, the connecting passage 58 and the air passage 70 will be blocked, and the drainage will not flow from the inner portion 56 to the air passage. 70 circulation.

此外，雖然通氣道70與外筐41中水平管14的連接位置之內側部56係藉由連通道58來加以連接，但如圖11所示，也可以為省略連通道58，且使通氣道70僅往上方敞開而不往下方側敞開之構成。另外，如圖11所示，也可以為省略圖5所示之凸緣64的構成。此情形，通氣道70之上端也可以位於較內筐42之排水窗42A要上方。其原因在於：通過水封34而從排水窗42A流出之排水會不易流入通氣道70。In addition, although the air passage 70 and the inner part 56 of the connection position of the horizontal tube 14 in the outer basket 41 are connected by the connecting passage 58, as shown in FIG. 11, the connecting passage 58 may be omitted and the air passage 70 is a structure that only opens to the upper side and not to the lower side. In addition, as shown in FIG. 11, the flange 64 shown in FIG. 5 may be omitted. In this case, the upper end of the air passage 70 may also be located above the drain window 42A of the inner basket 42. The reason is that the drain water flowing out from the drain window 42A through the water seal 34 will not easily flow into the air passage 70.

關於其他部分係與第1實施形態或第2實施形態相同，因此在圖式中會對相同部分賦予相同符號以省略說明。The other parts are the same as in the first embodiment or the second embodiment, and therefore the same parts are given the same reference numerals in the drawings to omit the description.

(作用) 本參考例係如上述般構成，以下說明其作用。圖4、圖5中，排水構造30係在排水捕集器12之外筐41內部形成有與通氣管16連通且朝向上方延伸至地板材22之高度位置的通氣道70，因此即使通氣管16配置在不會與地板材22產生干擾之位置，也可抑制已通過水封34的排水堵塞通氣管16的情形。藉此，可順暢地進行較排水捕集器12內之水封34要下游側之空氣的交換，並使該空氣往通氣管16流動。因此，可抑制空氣滯留在較排水捕集器12內之水封34要下游側的情形。(effect) This reference example is configured as described above, and its function will be described below. In FIGS. 4 and 5, the drainage structure 30 is formed inside the outer basket 41 of the drainage trap 12 with a ventilation passage 70 communicating with the ventilation pipe 16 and extending upward to the height of the floor 22. Therefore, the ventilation pipe 16 It is also arranged at a position where it does not interfere with the floor material 22, and it is also possible to prevent the drain pipe 16 that has passed through the water seal 34 from clogging. Thereby, it is possible to smoothly exchange the air on the downstream side of the water seal 34 in the drainage trap 12 and to make the air flow to the vent pipe 16. Therefore, it is possible to prevent air from staying on the downstream side of the water seal 34 in the drain trap 12.

另外，由於通氣道70與外筐41中水平管14的連接位置之內側部56係藉由連通道58來加以連接，且在連通道58之內部設有浮閥62，因此能將空氣從連通於連通道58之上述內側部56往通氣道70排出，且能抑制排水從連通於連通道58之上述內側部56往通氣道70流入。另外，即使排水流入通氣道70之情形，該排水也會通過連通道58而從上述內側部56往水平管14排出。In addition, since the air passage 70 and the inner part 56 of the connection position of the horizontal pipe 14 in the outer basket 41 are connected by the connecting passage 58, and a float valve 62 is provided inside the connecting passage 58, the air can be communicated from The inner portion 56 of the connecting passage 58 is discharged to the air passage 70, and the drainage of water from the inner portion 56 connected to the connecting passage 58 can be prevented from flowing into the air passage 70. In addition, even if the drain water flows into the air passage 70, the drain water is discharged from the inner side portion 56 to the horizontal pipe 14 through the connecting channel 58.

再者，由於在通氣道70之上端設有遮蔽通氣道70往上方敞開的凸緣64，因此可抑制已通過水封34的排水流入通氣道70的情形。藉此，可確保空氣從通氣道70往通氣管16的通道，因此可抑制空氣滯留在較排水捕集器12內之水封34要下游側的情形。Furthermore, since the upper end of the air passage 70 is provided with a flange 64 that shields the air passage 70 from opening upward, it is possible to prevent the drainage that has passed through the water seal 34 from flowing into the air passage 70. As a result, the passage of air from the air duct 70 to the air duct 16 can be ensured, and therefore, it is possible to prevent air from staying on the downstream side of the water seal 34 in the drain trap 12.

另外，此排水構造30中，在外筐41之徑向上係使通氣道70之寬度較連通道58之寬度要小。另外，通氣道70之第1壁部71與連通道58之第2壁部72係藉由相對於外筐41之上下方向傾斜的傾斜壁部73而結合來加以連接。因此，排水捕集器12中，藉由從第1壁部71沿著傾斜壁部73來設置內筐42，便可確保內筐42之容量。因此，便能使排水捕集器12之高度尺寸小型化。In addition, in this drainage structure 30, the width of the air passage 70 in the radial direction of the outer basket 41 is made smaller than the width of the connecting passage 58. In addition, the first wall portion 71 of the air passage 70 and the second wall portion 72 of the connecting passage 58 are connected by an inclined wall portion 73 that is inclined with respect to the upper and lower directions of the outer basket 41. Therefore, in the drainage trap 12, by arranging the inner basket 42 from the first wall portion 71 along the inclined wall portion 73, the capacity of the inner basket 42 can be secured. Therefore, the height dimension of the drainage trap 12 can be miniaturized.

再者，此排水構造中，係使第1壁部71、傾斜壁部73及第2壁部72作為例如壁形成構件74而一體形成，且可從外筐41移除，因此藉由將壁形成構件74從外筐41移除，便能容易清掃排水捕集器12。Furthermore, in this drainage structure, the first wall portion 71, the inclined wall portion 73, and the second wall portion 72 are integrally formed as, for example, the wall forming member 74 and can be removed from the outer basket 41. Therefore, the wall By removing the forming member 74 from the outer basket 41, the drainage trap 12 can be easily cleaned.
