Description

排水腔室 Drainage chamber

本發明係關於一種虹吸式排水系統所使用之排水腔室。 The invention relates to a drainage chamber used in a siphon drainage system.

下述專利文獻1揭露有一種住宅設備，係使用排出泵，來從單室公寓的洗臉台下的地板下所配置之污水槽，將排水朝地板上之排出口流出。 The following Patent Document 1 discloses a residential device that uses a discharge pump to discharge drain water from a sink arranged under the floor under the washbasin of a studio apartment to a discharge port on the floor.

【先前技術文獻】 【Prior Technical Literature】

【專利文獻】 【Patent Literature】

專利文獻1：日本新型登記第3141360號公報 Patent Document 1: Japanese Model Registration No. 3141360

由於上述專利文獻1中，為了流出排水係使用排出泵，故需要動力。 Since the aforementioned Patent Document 1 uses a discharge pump to flow out of the drainage system, power is required.

本發明係考量上述事實，其目的在於提供一種不使用動力來將排水排出之腔室。 The present invention takes the above facts into consideration, and its purpose is to provide a chamber that does not use power to discharge drain water.

請求項1之排水腔室係具備有：儲存槽，係貫穿底板材而設置於底板下空間，並在該底板下空間中讓排水之導入管與導出管連接，而在儲存有該排水的狀態下，於上部形成有氣層部；以及防水盤，係被載置於該儲存槽。 The drainage chamber of claim 1 is provided with: a storage tank, which penetrates the bottom plate and is provided in the space under the bottom plate, and in the space under the bottom plate, the inlet pipe and the outlet pipe of the drainage are connected, and the drainage is stored in the state Below, an air layer is formed on the upper part; and a waterproof plate is placed in the storage tank.

請求項1之排水腔室係由於配置於底板下空間之儲存槽會貫穿底板材，故相較於將儲存槽僅設置於底板下空間的情況，儲存槽會較深，而可儲存較多排水。藉此，來提高排水的水位差壓力，而使得從導出管所流出之排水的水壓提高。藉此便無需用以讓排水流出之動力。 The drainage chamber of claim 1 is because the storage tank arranged in the space under the bottom plate penetrates the bottom plate, so compared to the case where the storage tank is only provided in the space under the bottom plate, the storage tank is deeper and can store more drainage . In this way, the water head pressure of the drainage is increased, and the water pressure of the drainage flowing from the outlet pipe is increased. This eliminates the need for power to let the drainage flow out.

又，由於儲存槽會貫穿底板材，故底板材之高度便不會因為儲存槽之深度而被限制。因此，便可確保排水腔室之排水能力，並可將底板材之高 度控制為較低。藉此便可提高起居室之天花板高度。 In addition, since the storage tank penetrates the bottom plate, the height of the bottom plate will not be restricted by the depth of the storage tank. Therefore, the drainage capacity of the drainage chamber can be ensured, and the height of the bottom plate can be reduced The degree of control is low. This can increase the ceiling height of the living room.

又，由於防水盤會被載置於儲存槽，故可使得排水從防水盤流入至儲存槽。因此，便無需鋪設從防水盤到排水腔室的橫拉配管。 In addition, since the waterproof pan is placed in the storage tank, the drain can flow from the waterproof pan to the storage tank. Therefore, there is no need to lay horizontal piping from the waterproof pan to the drainage chamber.

請求項2之排水腔室係在請求項1之排水腔室中，該防水盤係形成有可卸載的排水捕集器，而將排水從該排水捕集器流入至該儲存槽。 The drainage chamber of claim 2 is in the drainage chamber of claim 1, and the waterproof plate is formed with an unloadable drainage trap, and the drainage flows from the drainage trap to the storage tank.

根據請求項2之排水腔室，係可藉由卸載防水盤之排水捕集器，來進行儲存槽內部之清掃、點檢。因此，便可在將洗衣機載置於防水盤之狀態下進行日常儲存槽內部之清掃、點檢。又，由於會在防水盤形成有捕集器，故可掩蓋掉來自殘留在儲存槽之排水的臭氣。 According to the drainage chamber of claim 2, it is possible to clean and inspect the interior of the storage tank by unloading the drainage trap of the waterproof pan. Therefore, the daily cleaning and inspection of the inside of the storage tank can be performed while the washing machine is placed on the waterproof tray. In addition, since a trap is formed on the waterproof pan, the odor from the drainage remaining in the storage tank can be masked.

請求項3之排水腔室係在請求項1或2之排水腔室中，該導出管之直徑會形成為較該導入管之直徑要小。 The drainage chamber of claim 3 is in the drainage chamber of claim 1 or 2, and the diameter of the outlet pipe will be formed to be smaller than the diameter of the inlet pipe.

根據請求項3之排水腔室，藉由讓導出管之直徑成為該導入管之直徑要小，來讓流道面積變小，以提高流速。藉此便可提高排水能力。 According to the drainage chamber of claim 3, by making the diameter of the outlet pipe smaller than the diameter of the inlet pipe, the flow channel area is reduced to increase the flow rate. In this way, the drainage capacity can be improved.

請求項4之排水腔室係在請求項1至3的任一者之排水腔室中，該儲存槽係在該底板下空間連接有通氣管；該通氣管會貫穿該儲存槽所儲存之該排水，且在該氣層部開口。 The drainage chamber of claim 4 is in the drainage chamber of any one of claims 1 to 3, and the storage tank is connected with a vent pipe in the space under the floor; the vent pipe penetrates the storage tank stored Drain water and open in the gas layer.

根據請求項4之排水腔室，藉由通氣管會貫穿儲存槽所儲存之排水，便可使得通氣管之位置會較未貫穿排水的情況要低。因此，便可降低底板材之高度。 According to the drainage chamber of claim 4, the position of the vent pipe will be lower than that in the case where the vent pipe penetrates the drain water stored in the storage tank. Therefore, the height of the bottom plate can be reduced.

請求項5之排水腔室係在請求項1至4的任一者之排水腔室中，該防水盤會成為該儲存槽之蓋體，且形成為可卸載。 The drain chamber of claim 5 is in the drain chamber of any one of claims 1 to 4, and the waterproof pan will become the cover of the storage tank and is formed to be unloadable.

根據請求項5之排水腔室，若是將防水盤卸載的話，便可點檢儲存槽內部。因此，便會較卸載排水捕集器的情況要能詳細的保守點檢，並能提高清潔效率。 According to the drainage chamber of claim 5, if the waterproof pan is unloaded, the inside of the storage tank can be inspected. Therefore, compared with the situation of unloading the drainage trap, detailed and conservative inspection is required, and the cleaning efficiency can be improved.

根據本發明之排水腔室，便可不使用動力來將排水排出。 According to the drainage chamber of the present invention, the drainage can be discharged without using power.

(虹吸式排水系統) (Siphon drainage system)

圖1係顯示本實施形態相關之排水腔室20所適用的虹吸式排水系統10之概略構成的縱剖面圖。 Fig. 1 is a longitudinal sectional view showing a schematic configuration of a siphon drainage system 10 to which a drainage chamber 20 according to this embodiment is applied.

虹吸式排水系統10係利用虹吸力來將來自集水器具17的排水排出之排水設備，會被用於形成為多樓層的集合住宅12。 The siphon drainage system 10 is a drainage device that uses siphon force to discharge the drainage from the water collection device 17 and is used to form a multi-storey housing complex 12.

虹吸式排水系統10係具備有將排水流向下方的排水立管38，此排水立管38係在集合住宅12中被複數設置於俯視下的不同場所。例如圖7(A)的俯視圖所示，會上下方向(縱向)地被收納於以牆壁來區劃出集合住宅12之各樓層的各住屋12A、12B、12C、12D、12E、12F之配管空間(亦稱為管道空間、 PS等)15內，且如圖1所示，會貫穿集合住宅12各樓層的底板16。 The siphon drainage system 10 is provided with a drainage riser 38 for draining the drainage to flow downward, and this drainage riser 38 is installed in multiple locations in the multi-housing 12 in a plan view. For example, as shown in the top view of Fig. 7(A), the piping space of each house 12A, 12B, 12C, 12D, 12E, 12F that is stored in the vertical direction (vertical) of the multi-housing 12 is divided by walls. (Also known as pipe space, PS etc.) 15, and as shown in FIG.

集合住宅12之住屋12A係分別設置有複數集水器具17(洗臉台17A、洗衣機17B、浴室17C)，該等集水器具17係分別連接有將集水器具17所排出之排水流走的排水導入管18一端。又，排水導入管18另端會與排水腔室20連接，排水導入管18會以使排水腔室20側變低的方式來傾斜配設。 The housing 12A of the multi-housing 12 is respectively provided with a plurality of water collection appliances 17 (washstand 17A, washing machine 17B, bathroom 17C), and these water collection appliances 17 are respectively connected to drain the drain discharged from the water collection appliance 17 One end of the drainage pipe 18 is introduced. In addition, the other end of the drain inlet pipe 18 is connected to the drain chamber 20, and the drain inlet pipe 18 is arranged obliquely so that the side of the drain chamber 20 is lowered.

儲存槽26底面係以來自排水導入管18A、排水捕集器52、排水導入管18C之排水會分別從水平管32A、32B、32C排出之方式來形成有凹部22C、22D、22E。凹部22C、22D、22E係以讓排水流向圖3箭頭所示之方向的方式來加以傾斜。 The bottom surface of the storage tank 26 is formed with recesses 22C, 22D, and 22E such that the drain from the drain inlet pipe 18A, the drain trap 52, and the drain inlet pipe 18C is discharged from the horizontal pipes 32A, 32B, and 32C, respectively. The recesses 22C, 22D, and 22E are inclined so as to allow the drain to flow in the direction indicated by the arrow in FIG. 3.

如圖4、5所示，凹部22C、22D、22E係在剖面觀察下為半圓狀之流水道，在例如水面H所示般，來自排水導入管18A、排水捕集器58、排水導入管18C之排水量較少的情況，各別的排水便會通過凹部22C、22D、22E來朝水平管32A、32B、32C排出。又，在排水量較多的情況，各別的排水會混合，而將混合後之排水朝水平管32A、32B、32C排出。 As shown in Figures 4 and 5, the recesses 22C, 22D, and 22E are semicircular water channels in cross-sectional view, and are drawn from the drainage introduction pipe 18A, the drainage trap 58, and the drainage introduction pipe 18C as shown in the water surface H, for example. When the drainage volume is small, the respective drainage will be discharged to the horizontal pipes 32A, 32B, and 32C through the recesses 22C, 22D, and 22E. In addition, when the drainage volume is large, the separate drainages are mixed, and the mixed drainage is discharged to the horizontal pipes 32A, 32B, and 32C.

(防水盤) (Waterproof plate)

如圖2所示，儲存槽26上部係在可卸載的狀態下來載置有防水盤50。亦即，防水盤50會兼作儲存槽26之蓋體。防水盤50係於上部載置有洗衣機17B的接收皿，且為抑制來自洗衣機17B之排水漏出於底板材40表面的止水構件。又，防水盤50之底部56係安裝有可卸載的排水捕集器58，此排水捕集器58係可安裝有連接洗衣機17B(參照圖1)之排水軟管的彎管59。 As shown in FIG. 2, the waterproof pan 50 is placed on the upper part of the storage tank 26 in a state where it can be unloaded. That is, the waterproof tray 50 will double as the cover of the storage tank 26. The waterproof pan 50 is a receiving pan on which the washing machine 17B is placed on the upper part, and is a water stop member that prevents the drain from the washing machine 17B from leaking out of the surface of the bottom plate 40. In addition, the bottom 56 of the waterproof tray 50 is equipped with a removable drain trap 58, which can be installed with an elbow 59 connected to the drain hose of the washing machine 17B (refer to FIG. 1).

藉此，來自洗衣機17B之排水會經由排水捕集器58而朝儲存槽26之儲存部22排出。如圖4、5所示，排水捕集部58之噴出口58B會在儲存槽26底面所形成之凹部22D上部開口，而使得來自洗衣機17B之排水主要會通過凹部22D而朝水平管32B排出。 Thereby, the drain water from the washing machine 17B is discharged to the storage portion 22 of the storage tank 26 through the drain trap 58. As shown in FIGS. 4 and 5, the ejection port 58B of the drain trap 58 opens at the upper part of the recess 22D formed on the bottom surface of the storage tank 26, so that the drain from the washing machine 17B is mainly discharged through the recess 22D to the horizontal pipe 32B.

又，如圖2所示，防水盤50周緣部係形成有用以防止洗衣排水漏出的上抬部52，如圖6所示，防水盤50角部係形成有設置洗衣機17B之腳的架高部54。另外，關於此架高部54係可省略。又，底部56之排水捕集部58的位置可為任意設置，只要能讓噴出口58B開口在凹部22D上部即可。又，底部56並非一定要設置排水捕集部58，亦可構成為設置可連接洗衣機17之排水軟管之連接口。 In addition, as shown in FIG. 2, the peripheral edge of the waterproof tray 50 is formed with a raised portion 52 to prevent the leakage of the laundry drain. As shown in FIG. 6, the corner of the waterproof tray 50 is formed with a raised portion where the feet of the washing machine 17B are formed. 54. In addition, regarding this elevated portion 54 series can be omitted. In addition, the position of the drainage collection part 58 of the bottom part 56 can be set arbitrarily, as long as the discharge port 58B can be opened in the upper part of the recessed part 22D. In addition, the bottom part 56 does not necessarily have to be provided with the drain trap 58, and it may be configured to provide a connection port to which the drain hose of the washing machine 17 can be connected.

(作用‧效果) (Effect)

本實施形態之排水腔室20如圖2所示，係配置為儲存槽26會貫穿底板材40。因此，相較於儲存槽未貫穿底板材40，而僅被收納於底板下空間內之構成，便可使得囤積排水之儲存部22更深。藉此來提高排水之水位差壓力，以提高從水平管32A、32B、32C所流出之排水的水壓。從而，便可提高虹吸效果。 As shown in FIG. 2, the drainage chamber 20 of this embodiment is configured such that the storage tank 26 penetrates the bottom plate 40. Therefore, compared with the structure in which the storage tank does not penetrate the bottom plate 40 but is only stored in the space under the bottom plate, the storage portion 22 for storing drainage can be made deeper. In this way, the water level difference pressure of the drainage is increased to increase the water pressure of the drainage flowing from the horizontal pipes 32A, 32B, and 32C. Thus, the siphon effect can be improved.

另外，儲存槽26(儲存部22)之深度可任意設置。例如圖8所示，可提高凸緣部26A起自底板材40之上抬高度，來加深儲存槽26。藉由此般構成便可進一步地提高虹吸效果。 In addition, the depth of the storage tank 26 (storage portion 22) can be set arbitrarily. For example, as shown in FIG. 8, the height of the flange portion 26A from the bottom plate 40 can be increased to deepen the storage tank 26. With this structure, the siphon effect can be further improved.

又，水平管32及流出垂直管34之直徑(內徑)會成為較排水導入管18之直徑(內徑)要小徑。藉此來提高排水之流速，而能提高虹吸效果。 In addition, the diameter (inner diameter) of the horizontal pipe 32 and the outflow vertical pipe 34 will be smaller than the diameter (inner diameter) of the drainage introduction pipe 18. In this way, the flow rate of the drainage can be increased, and the siphon effect can be improved.

又，藉由提高排水之流速，便會使得污垢難以附著於水平管32及流出垂直管34內部。又，即便在已附著的情況下，仍容易被洗淨。 In addition, by increasing the flow rate of the drainage, it will be difficult for dirt to adhere to the horizontal pipe 32 and out of the vertical pipe 34. Moreover, even if it is attached, it is easy to be washed away.

又，本實施形態之排水腔室20中，主要會流通來自洗臉台17A之排水的水平管32A、主要會流通來自洗衣機17B之排水的水平管32B以及主要會流通來自浴室17C之排水的水平管32C會依序被連接於儲存槽26。 In addition, in the drainage chamber 20 of the present embodiment, the horizontal pipe 32A mainly circulates the drain from the washstand 17A, the horizontal pipe 32B mainly circulates the drain from the washing machine 17B, and the horizontal pipe mainly circulates the drain from the bathroom 17C 32C will be connected to the storage tank 26 in sequence.

因此，雖來自使用頻率高且排水量多的洗衣機17B的排水會流通在排水腔室20中央部所形成之凹部22D而朝水平管32B排出，但此排水亦會流通於 凹部22C、22E而朝水平管32A、32C排出。從而，即便在例如浴室17C之使用頻率低之住屋中，仍可洗淨主要會流通來自浴室17C的排水之水平管32C內部。 Therefore, although the drain from the washing machine 17B with a high frequency of use and a large amount of drainage flows through the recess 22D formed in the center of the drain chamber 20 and is discharged toward the horizontal pipe 32B, the drain also flows through The recesses 22C, 22E are discharged toward the horizontal pipes 32A, 32C. Therefore, even in a house where the use frequency of the bathroom 17C is low, the inside of the horizontal pipe 32C that mainly circulates the drainage from the bathroom 17C can be cleaned.

又，藉由提高排水之水壓及流速，即便從排水腔室20到配管空間15的距離(水平管32之橫拉距離)較長，仍可藉由虹吸效果來流通來自洗臉台17A或浴室17C的排水。 In addition, by increasing the water pressure and flow rate of the drainage, even if the distance from the drainage chamber 20 to the piping space 15 (the horizontal distance of the horizontal pipe 32) is long, the siphon effect can still circulate from the washstand 17A or the bathroom 17C drainage.

例如圖7(A)係概略性地顯示標準構成之集合住宅的住屋12A~12F中之集水器具17(洗臉台17A、洗衣機17B、浴室17C)的配置。 For example, FIG. 7(A) schematically shows the arrangement of the water collection appliance 17 (washstand 17A, washing machine 17B, bathroom 17C) in the houses 12A to 12F of the multi-housing with a standard configuration.

在標準構成的集合住宅中，為了從屋外採光，大部分都是在走廊側配置有寢室，於陽台側配置有客廳，而集水器具17則會被配置於靠近住屋內側。然後，配管空間15最好是以點檢作業員容易處理的方式，以及以排水聲音難以讓住屋空間聽到的方式來設置於以牆壁來區劃出住屋12A~12F之位置。 In a multi-housing with a standard structure, in order to take in light from outside, most of the bedrooms are arranged on the corridor side, the living room is arranged on the balcony side, and the water collection device 17 is arranged close to the inside of the house. Then, the piping space 15 is preferably installed in a way that is easy for inspection operators to handle, and that the drainage sound is difficult to hear from the housing space, and is preferably installed at a location where the walls divide the housing 12A to 12F.

然而，如圖7(C)所示，為了在集水空間得到採光，或是在入浴時眺望屋外之風景，而將集水器具17及排水腔室20配置於住屋12A~12F的屋外側(陽台側)時，便會使得到配管空間15為止之水平管32的橫拉距離變長。在此情況下，將排水腔室20僅收納於底板下空間內時，便無法得到充分虹吸效果。 However, as shown in Fig. 7(C), in order to obtain light in the water collection space or to look out the scenery outside the house when bathing, the water collection appliance 17 and the drainage chamber 20 are arranged outside the house 12A~12F. In the case of (balcony side), the horizontal drawing distance of the horizontal pipe 32 until the piping space 15 is obtained becomes longer. In this case, when the drainage chamber 20 is only accommodated in the space under the floor, a sufficient siphon effect cannot be obtained.

因此，在將排水腔室20僅收納於底板下空間內的情況，係如圖7(B)所示，最好是有將配管空間15設置於靠近住屋12A~12F內部的排水腔室20，以縮短水平管32之橫拉距離的對策。 Therefore, when the drainage chamber 20 is stored only in the space under the floor, as shown in FIG. 7(B), it is preferable to provide the piping space 15 in the drainage chamber 20 close to the interior of the houses 12A to 12F. , In order to shorten the horizontal length of the pipe 32 of the countermeasures.

相對於此，由於本實施形態之排水腔室20中，係排水腔室20之儲存槽26會貫穿底板材40而加以配置，故會提高虹吸效果。因此，如圖7(C)所示，即便水平管32之橫拉距離較長，仍能不讓排水滯留而流通。 In contrast, in the drainage chamber 20 of the present embodiment, the storage tank 26 of the drainage chamber 20 is arranged through the bottom plate 40, so the siphon effect is improved. Therefore, as shown in FIG. 7(C), even if the horizontal pipe 32 has a long horizontal drawing distance, it is possible to circulate the drainage without stagnating.

從而，便可將配管空間15設置於以牆壁區劃出住屋12A~12F之位置。如此般，根據本實施形態之排水腔室20，便能提高集水器具17之配置計畫的自由度。 Therefore, the piping space 15 can be installed at the position where the walls 12A to 12F are partitioned. In this way, according to the drainage chamber 20 of the present embodiment, the degree of freedom of the arrangement plan of the water collection device 17 can be increased.

又，本實施形態中，如圖2所示，防水盤50會兼作儲存槽26之蓋體，而形成為可卸載。進一步地，排水捕集部58係形成為可從防水盤50卸載。因 此，藉由卸載防水盤50，便可點檢、清掃儲存槽26內部。又，在平常點檢時，即便不卸載防水盤50，仍可藉由卸載排水捕集部58來查看儲存槽26內部。相對於此，在例如分別構成儲存槽26與防水盤50，並分別配置在不同平面位置的情況，便需要在底板材40設置儲存槽26之點檢口。 In addition, in this embodiment, as shown in FIG. 2, the waterproof pan 50 also serves as the cover of the storage tank 26 and is formed to be unloadable. Furthermore, the drainage trap 58 is formed so as to be unloadable from the waterproof pan 50. because Therefore, by unloading the waterproof tray 50, the inside of the storage tank 26 can be inspected and cleaned. In addition, at the time of normal inspection, even if the waterproof pan 50 is not unloaded, the inside of the storage tank 26 can be inspected by unloading the drain trap 58. On the other hand, when the storage tank 26 and the waterproof pan 50 are formed separately and are arranged in different plane positions, for example, it is necessary to provide a check port for the storage tank 26 in the bottom plate 40.

另外，雖在本實施形態之排水腔室20中，防水盤50及防水盤50所形成之排水捕集器58兩者都可卸載，但本發明實施形態並不限於此。例如即便防水盤50非為可卸載，仍可靠卸載排水捕集器58來點檢、清掃儲存槽26。或著，即便排水捕集器58非為可卸載，仍可靠卸載防水盤50來點檢、清掃儲存槽26。 In addition, although in the drainage chamber 20 of the present embodiment, both the waterproof pan 50 and the drainage trap 58 formed by the waterproof pan 50 can be unloaded, the embodiment of the present invention is not limited to this. For example, even if the waterproof tray 50 is not unloadable, the drain trap 58 is still reliably unloaded to check and clean the storage tank 26. Or, even if the drain trap 58 is not unloadable, the waterproof tray 50 is still reliably unloaded to check and clean the storage tank 26.

又，雖在本實施形態之排水腔室20中，如圖2所示，係構成為將儲存槽26與防水盤50分別構成，而將防水盤50載置於儲存槽26上部，但本發明之實施形態並不限於此。 In addition, although the drainage chamber 20 of this embodiment, as shown in FIG. 2, is configured such that the storage tank 26 and the waterproof pan 50 are formed separately, and the waterproof pan 50 is placed on the upper part of the storage tank 26, the present invention The implementation form is not limited to this.

亦可例如圖9所示之排水腔室60般，構成為將囤積排水之儲存槽部分62、設置洗衣機之架高部64以及防止朝底板材40上部漏水的上抬部66一體形成，而可卸載儲存槽部分之蓋體68。若是排水腔室為此般構成，由於儲存槽部分會兼作防水盤，故可減少需要止水處理的部位。從而，便可將排水設備之構成單純化。 For example, the drainage chamber 60 shown in FIG. 9 can also be configured to integrally form a storage tank portion 62 for storing drainage, a rack portion 64 for installing a washing machine, and a raised portion 66 for preventing water leakage toward the upper part of the bottom plate 40, and can be Unload the cover 68 of the storage tank part. If the drainage chamber is constructed in this way, since the storage tank part doubles as a waterproof pan, the parts that need water-stop treatment can be reduced. Thus, the composition of the drainage equipment can be simplified.

又，雖在本實施形態之排水腔室20中，如圖2所示，係儲存槽26之凸緣部26A會以覆蓋底板材40之貫穿孔緣部的方式來加以配置，但本發明之實施形態並不限於此。 In addition, in the drainage chamber 20 of this embodiment, as shown in FIG. 2, the flange portion 26A of the storage tank 26 is arranged so as to cover the edge of the through hole of the bottom plate 40, but the present invention is The embodiment is not limited to this.

亦可例如圖10所示之排水腔室70般，以將儲存槽72之凸緣部72A從底板材40上部延設至下部(底板下空間)，而將凸緣部72A嵌合至底板材40之貫穿孔的方式來加以配置。藉由此般構成，便可一併設置排水導入管18、水平管32、通氣管36以及排水腔室70後，再鋪設底板材40。因此，便可使得設備工事與地板工事的工程管理變得容易。 It is also possible to extend the flange portion 72A of the storage tank 72 from the upper part of the bottom plate 40 to the lower part (under-floor space) like the drainage chamber 70 shown in FIG. 10, and the flange part 72A is fitted to the bottom plate 40 through holes to be configured. With this configuration, the drainage introduction pipe 18, the horizontal pipe 32, the vent pipe 36, and the drainage chamber 70 can be installed together, and then the bottom plate 40 can be laid. Therefore, the engineering management of equipment construction and floor construction can be made easy.

另外，雖在本實施形態之排水腔室20中，係將通氣管36連接於儲存槽26，但本發明之實施形態並不限於此。亦可藉由例如在儲存槽26使用通氣閥等的閥體，來通氣至儲存槽26。 In addition, although the vent pipe 36 is connected to the storage tank 26 in the drain chamber 20 of this embodiment, the embodiment of the present invention is not limited to this. It is also possible to vent to the storage tank 26 by using a valve body such as a vent valve in the storage tank 26, for example.
