Description

本開示は、排水弁装置及びサッシ窓に関する。 The present disclosure relates to drain valve devices and sash windows.

サッシ窓には、屋外から吹き付ける雨が屋内側に浸入することを防ぐ水密性能が求められる。雨が屋外からサッシ窓に強く吹き付けると、例えば、サッシ窓の縦枠と下枠との接続部から下枠内の中空部に水が浸入して溜まる場合がある。サッシ窓の水密性能を向上させるためには、下枠の中空部に溜まった水を屋外に円滑に排出することが求められる。 The sash window is required to have watertightness to prevent rain from the outside from entering the indoor side. When rain is strongly blown onto the sash window from the outside, for example, water may infiltrate and collect in the hollow portion in the lower frame from the connection portion between the vertical frame and the lower frame of the sash window. In order to improve the watertightness of the sash window, it is required to smoothly discharge the water accumulated in the hollow portion of the lower frame to the outside.

従来、下枠の中空部に溜まった水を排出するために、下枠の中空部に屋外側に向けて開口する排水口を設け、排水口の上部を支点に外側方向にのみ開閉自在に羽根状の排水弁を取り付けることが知られている（例えば、特許文献１参照）。 Conventionally, in order to drain the water accumulated in the hollow part of the lower frame, a drainage port that opens toward the outdoor side is provided in the hollow part of the lower frame, and the blade can be opened and closed only in the outward direction with the upper part of the drainage port as a fulcrum. It is known to attach a drain valve having a shape (see, for example, Patent Document 1).

特開２００２－２２７５４６号公報Japanese Unexamined Patent Publication No. 2002-227546

排水弁は、通常時は閉じた状態にすることでサッシ窓からの漏気を防止する一方、降雨時にはサッシ窓の下枠の中空部に溜まった水の圧力で屋外側に開いて排水を行うことで、屋内側への水の浸入を防止する。しかし、排水弁は前方からの風圧を受けると開きにくくなるため、強風を伴う降雨の際には、排水性が低下するおそれがある。 The drain valve is normally closed to prevent air leakage from the sash window, while when it rains, it opens to the outside due to the pressure of the water accumulated in the hollow part of the lower frame of the sash window to drain water. This prevents water from entering the indoor side. However, since the drain valve is difficult to open when it receives wind pressure from the front, the drainage property may deteriorate when it rains with a strong wind.

従来、強風を伴う降雨時においても排水性を低下させないためには、下枠に大きな中空部を形成し、多くの水を溜めて、水の圧力を高めるという手段がとられてきた。 Conventionally, in order not to reduce the drainage property even in the case of rainfall accompanied by strong wind, a means has been taken in which a large hollow portion is formed in the lower frame to store a large amount of water and increase the pressure of the water.

しかしながら、下枠に大きな中空部を設けると、より多くの材料が必要となり、コストアップにつながるとともに、下枠の見付幅が太くなり、意匠的に優れないものになるという問題があった。 However, if a large hollow portion is provided in the lower frame, more materials are required, which leads to an increase in cost and a problem that the found width of the lower frame becomes wide and the design is not excellent.

したがって、サッシ窓の下枠の大きさに関係なく、下枠の中空部の排水性能を向上することができる排水弁装置及びサッシ窓が求められる。 Therefore, there is a need for a drain valve device and a sash window that can improve the drainage performance of the hollow portion of the lower frame regardless of the size of the lower frame of the sash window.

本開示に係る排水弁装置は、サッシ窓の下枠の屋外側壁部に設けられる排水口に取り付けられ、前記排水口に連通する流入口と、前記流入口を屋外に連通させる流出口と、を有する筐体と、前記流出口に開閉可能に取り付けられる排水弁と、を備え、前記流出口は、前記流入口よりも鉛直方向の下方に配置される。 The drain valve device according to the present disclosure is attached to a drain port provided on the outdoor side wall portion of the lower frame of the sash window, and has an inlet that communicates with the drain port and an outlet that communicates the inlet to the outside. It includes a housing having a housing and a drain valve that can be opened and closed at the outlet, and the outlet is arranged below the inlet in the vertical direction.

枠体２は、上枠２１、下枠２２、及び左右の縦枠２３，２４を矩形に枠組みすることによって構成される。図２に示すように、上枠２１は、屋内外方向に平行に配置されるレール２１１ａ，２１１ｂ，２１１ｃを有する。下枠２２は、屋内外方向に平行に配置されるレール２２１ａ，２２１ｂ，２２１ｃを有する。最も屋外側に配置される上枠２１のレール２１１ａと下枠２２のレール２２１ａとの間には、網戸４が、枠体２内を左右方向に移動可能に納められる。上枠２１のレール２１１ｂ，２１１ｃと下枠２２のレール２２１ｂ，２２１ｃとの間には、それぞれ障子３，３が、枠体２内を左右方向に移動可能に納められる。 The frame body 2 is configured by framing the upper frame 21, the lower frame 22, and the left and right vertical frames 23, 24 in a rectangular shape. As shown in FIG. 2, the upper frame 21 has rails 211a, 211b, 211c arranged in parallel in the indoor and outdoor directions. The lower frame 22 has rails 221a, 221b, 221c arranged in parallel in the indoor and outdoor directions. A screen door 4 is housed between the rail 211a of the upper frame 21 and the rail 221a of the lower frame 22 arranged on the most outdoor side so as to be movable in the frame body 2 in the left-right direction. The shoji screens 3 and 3 are housed between the rails 211b and 211c of the upper frame 21 and the rails 221b and 221c of the lower frame 22 so as to be movable in the left-right direction in the frame body 2, respectively.

図２に示すように、下枠２２は、内部に中空部２２２を有する。中空部２２２は、上側壁部２２３と、下側壁部２２４と、屋外側壁部２２５と、屋内側壁部２２６と、によって形成される。屋外側壁部２２５は、下枠２２の屋外側の見付面を形成する。中空部２２２は、下枠２２の全長に亘って延在している。 As shown in FIG. 2, the lower frame 22 has a hollow portion 222 inside. The hollow portion 222 is formed by an upper side wall portion 223, a lower side wall portion 224, an outdoor side wall portion 225, and an indoor side wall portion 226. The outdoor side wall portion 225 forms a finding surface on the outdoor side of the lower frame 22. The hollow portion 222 extends over the entire length of the lower frame 22.

下枠２２の屋外側壁部２２５には、中空部２２２に溜まった水を屋外に排出するための横長矩形状の排水口２２７が設けられる。排水口２２７は、屋外側壁部２２５の左右方向の両端部近傍であって、下側壁部２２４に近接する位置にそれぞれ配置される。排水口２２７には、それぞれ排水弁装置が取り付けられる。 The outdoor side wall portion 225 of the lower frame 22 is provided with a horizontally long rectangular drainage port 227 for draining the water accumulated in the hollow portion 222 to the outside. The drainage port 227 is arranged at a position close to both ends of the outdoor side wall portion 225 in the left-right direction and close to the lower side wall portion 224. A drain valve device is attached to each of the drain ports 227.

第１の実施形態に係る排水弁装置５について、図１～図７を参照して詳細に説明する。排水弁装置５は、図３及び図７に示すように、いずれも樹脂製の筐体５１と排水弁５２とによって構成される。 The drain valve device 5 according to the first embodiment will be described in detail with reference to FIGS. 1 to 7. As shown in FIGS. 3 and 7, the drain valve device 5 is composed of a resin housing 51 and a drain valve 52.

筐体５１は、図３に示すように、下枠２２の屋外側壁部２２５に当接する横長矩形状のフランジ部５１１と、フランジ部５１１から屋外側且つ鉛直方向の下方に延びる略直方体形の筐体本体５１２とによって構成される。フランジ部５１１と筐体本体５１２とは一体に形成されている。 As shown in FIG. 3, the housing 51 has a horizontally long rectangular flange portion 511 that abuts on the outdoor side wall portion 225 of the lower frame 22, and a substantially rectangular parallelepiped housing that extends from the flange portion 511 to the outdoor side and downward in the vertical direction. It is composed of a body body 512. The flange portion 511 and the housing body 512 are integrally formed.

フランジ部５１１は、図５に示すように、屋外側壁部２２５に設けられる排水口２２７の開口面積よりも大きい。フランジ部５１１には、排水口２２７に連通し、排水口２２７から排出される中空部２２２内の水を受け入れる横長矩形状の流入口５３が開口している。 As shown in FIG. 5, the flange portion 511 is larger than the opening area of the drain port 227 provided in the outdoor side wall portion 225. The flange portion 511 is opened with a horizontally long rectangular inflow port 53 that communicates with the drain port 227 and receives water in the hollow portion 222 discharged from the drain port 227.

図４及び図５に示すように、フランジ部５１１の屋内側の側面５１１ａには、流入口５３を取り囲んで屋内側に向けて突出する横長矩形状の取付筒部５４が設けられる。筐体５１は、取付筒部５４が屋外側から排水口２２７に挿入されることによって、排水口２２７に取り付けられる。取付筒部５４の上面５４ａには、上方に向けて山型状に突出する２つの係止爪５４１，５４１が設けられる。取付筒部５４の左右側面５４ｂ，５４ｂには、側方に向けて山型状に突出する係止爪５４２，５４２がそれぞれ設けられる。図５に示すように、取付筒部５４が排水口２２７内に挿入された際に、係止爪５４１，５４１は、排水口２２７の上側の内周部２２７ａに係止し、係止爪５４２，５４２は、排水口２２７の左右の内周部２２７ｂ，２２７ｂに係止する。これによって、筐体５１は、排水口２２７に対して着脱可能に取り付けられる。 As shown in FIGS. 4 and 5, the side surface 511a on the indoor side of the flange portion 511 is provided with a horizontally long rectangular mounting cylinder portion 54 that surrounds the inflow port 53 and projects toward the indoor side. The housing 51 is attached to the drainage port 227 by inserting the mounting cylinder portion 54 into the drainage port 227 from the outdoor side. Two locking claws 541 and 541 that project upward in a chevron shape are provided on the upper surface 54a of the mounting cylinder portion 54. Locking claws 542 and 542 that project laterally in a mountain shape are provided on the left and right side surfaces 54b and 54b of the mounting cylinder portion 54, respectively. As shown in FIG. 5, when the mounting cylinder portion 54 is inserted into the drain port 227, the locking claws 541 and 541 are locked to the inner peripheral portion 227a on the upper side of the drain port 227, and the locking claw 542 is engaged. , 542 are locked to the left and right inner peripheral portions 227b and 227b of the drainage port 227. As a result, the housing 51 is detachably attached to the drain port 227.

図７に示すように、筐体本体５１２は、フランジ部５１１から屋外側に向けて突出するとともに、流入口５３よりも鉛直方向下方に延びている。筐体本体５１２の内部は、流入口５３と連通している。筐体本体５１２は、屋外に向けて開口する流出口５５を有する。流出口５５は、筐体本体５１２の屋外側及び下方に向けて開放するように形成される。これによって、筐体本体５１２の内部の流路は、流入口５３から屋外側に向かい、下方に向けて略直角に屈曲した後、筐体本体５１２の下端の流出口５５において屋外に連通する。筐体本体５１２の下端に配置される内底面５１２ａは、排水口２２７の下端の位置よりも高さＨ１だけ鉛直方向の下方に離れて配置される。 As shown in FIG. 7, the housing main body 512 protrudes from the flange portion 511 toward the outdoor side and extends vertically downward from the inflow port 53. The inside of the housing body 512 communicates with the inflow port 53. The housing body 512 has an outlet 55 that opens toward the outside. The outlet 55 is formed so as to open toward the outdoor side and the downward side of the housing body 512. As a result, the internal flow path of the housing body 512 faces the outdoor side from the inflow port 53, bends downward at a substantially right angle, and then communicates with the outside at the outlet 55 at the lower end of the housing body 512. The inner bottom surface 512a arranged at the lower end of the housing body 512 is arranged vertically below the position of the lower end of the drainage port 227 by a height H1.

排水弁５２は、図３、図６及び図７に示すように、下枠２２の延び方向に沿う回転軸部５２１と、回転軸部５２１から下方に延びる矩形板状の弁体部５２２と、を有する。回転軸部５２１の両端は、筐体本体５１２の左右の側壁部５１２ｂ，５１２ｂにそれぞれ設けられる取付孔５１２ｃ，５１２ｃに挿入されている。これによって、排水弁５２は、流出口５５の屋外側に、流出口５５の上部に配置される回転軸部５２１を中心にして開閉可能に取り付けられる。 As shown in FIGS. 3, 6 and 7, the drain valve 52 includes a rotary shaft portion 521 along the extending direction of the lower frame 22 and a rectangular plate-shaped valve body portion 522 extending downward from the rotary shaft portion 521. Has. Both ends of the rotating shaft portion 521 are inserted into mounting holes 512c and 512c provided in the left and right side wall portions 512b and 512b of the housing body 512, respectively. As a result, the drain valve 52 is attached to the outdoor side of the outlet 55 so as to be openable and closable around the rotary shaft portion 521 arranged above the outlet 55.

排水弁５２の弁体部５２２は、図６及び図７に示すように、屋内側に向けて略Ｌ字状に屈曲した先端部５２２ａを有する。弁体部５２２の屋内側面には、複数のリブ５２３が設けられる。リブ５２３は、回転軸部５２１の近傍から弁体部５２２の先端部５２２ａにかけて三角形の板状に形成される。本実施形態の排水弁５２は、３つのリブ５２３を有する。３つのリブ５２３は、弁体部５２２の幅方向の両端と中央とに配置される。 As shown in FIGS. 6 and 7, the valve body portion 522 of the drain valve 52 has a tip portion 522a bent in a substantially L shape toward the indoor side. A plurality of ribs 523 are provided on the indoor side surface of the valve body portion 522. The rib 523 is formed in a triangular plate shape from the vicinity of the rotation shaft portion 521 to the tip portion 522a of the valve body portion 522. The drain valve 52 of this embodiment has three ribs 523. The three ribs 523 are arranged at both ends and the center of the valve body portion 522 in the width direction.

排水弁５２は、図７の実線で示すように、弁体部５２２の先端部５２２ａが流出口５５の開口端面５５ａに当接することによって、流出口５５を屋外側から閉鎖する。これによって、排水弁５２は、開放時に、回転軸部５２１を中心にして屋外側のみに向けて移動する。排水弁５２の幅方向の両側は、図３に示すように、筐体本体５１２の左右の側壁部５１２ｂ，５１２ｂによって封鎖されている。 As shown by the solid line in FIG. 7, the drain valve 52 closes the outlet 55 from the outdoor side when the tip portion 522a of the valve body portion 522 abuts on the open end surface 55a of the outlet 55. As a result, the drain valve 52 moves toward the outdoor side only with the rotation shaft portion 521 as the center when the drain valve 52 is opened. As shown in FIG. 3, both sides of the drain valve 52 in the width direction are closed by the left and right side wall portions 512b and 512b of the housing body 512.

排水弁５２の弁体部５２２は、図６及び図７に示すように、略Ｌ字状に形成されるため、回転軸部５２１側の厚みよりも先端部５２２ａ側の厚みの方が大きい。すなわち、弁体部５２２は、回転軸部５２１側よりも、回転軸部５２１から遠い先端部５２２ａの方が重い。そのため、屋内側からの水の圧力が排水弁５２に作用しない場合、先端部５２２ａは自重によって下向きに移動し、流出口５５の閉鎖状態を安定的に維持する。 As shown in FIGS. 6 and 7, the valve body portion 522 of the drain valve 52 is formed in a substantially L shape, so that the thickness on the tip portion 522a side is larger than the thickness on the rotation shaft portion 521 side. That is, the valve body portion 522 is heavier at the tip portion 522a far from the rotating shaft portion 521 than at the rotating shaft portion 521 side. Therefore, when the pressure of water from the indoor side does not act on the drain valve 52, the tip portion 522a moves downward due to its own weight, and the closed state of the outlet 55 is stably maintained.

以上のように、第１の実施形態に係る排水弁装置５は、下枠２２の屋外側壁部２２５に設けられる排水口２２７に取り付けられ筐体５１と、流出口５５に開閉可能に取り付けられる排水弁５２と、を備える。筐体５１は、排水口２２７に連通する流入口５３と、流入口５３を屋外に連通させる流出口５５と、を有する。流出口５５は、流入口５３よりも鉛直方向の下方に配置される。流出口５５の下端、すなわち、筐体本体５１２の下端の内底面５１２ａは、図７に示すように、排水口２２７に対して高さＨ１だけ下方に配置されため、筐体５１内に流入した水の圧力は、高さＨ１に相当する水頭差によって増加する。そのため、本実施形態の排水弁装置５によれば、下枠２２が小さくて中空部２２２に溜められる水量が少なくても、排水弁５２は、筐体５１内に流入した水の圧力によって容易に開放することができる。これによって、排水弁装置５は、下枠２２の大きさに関係なく、下枠２２の中空部２２２の排水性能を向上させることができる。 As described above, the drain valve device 5 according to the first embodiment is attached to the drain port 227 provided on the outdoor side wall portion 225 of the lower frame 22, and is attached to the housing 51 and the outlet 55 so as to be openable and closable. It is provided with a valve 52. The housing 51 has an inflow port 53 communicating with the drainage port 227 and an outflow port 55 communicating the inflow port 53 outdoors. The outlet 55 is arranged below the inlet 53 in the vertical direction. As shown in FIG. 7, the lower end of the outflow port 55, that is, the inner bottom surface 512a of the lower end of the housing body 512, is arranged below the drain port 227 by the height H1 and thus flows into the housing 51. The pressure of water is increased by the head difference corresponding to the height H1. Therefore, according to the drain valve device 5 of the present embodiment, even if the lower frame 22 is small and the amount of water stored in the hollow portion 222 is small, the drain valve 52 can be easily driven by the pressure of the water flowing into the housing 51. It can be opened. Thereby, the drain valve device 5 can improve the drainage performance of the hollow portion 222 of the lower frame 22 regardless of the size of the lower frame 22.

次に、第２の実施形態に係る排水弁装置５Ａについて、図８、図９及び図１０を参照して詳細に説明する。第１の実施形態に係る排水弁装置５と同一符号の部位は同一構成の部位を示す。そのため、以下の説明において、第１実施形態に係る排水弁装置５と重複する説明は省略する。 Next, the drain valve device 5A according to the second embodiment will be described in detail with reference to FIGS. 8, 9 and 10. A portion having the same reference numeral as the drain valve device 5 according to the first embodiment indicates a portion having the same configuration. Therefore, in the following description, the description overlapping with the drain valve device 5 according to the first embodiment will be omitted.

排水弁装置５Ａは、上下に２分割された筐体５１を有する点で、第１の実施形態に係る排水弁装置５と相違する。詳しくは、排水弁装置５Ａの筐体５１の筐体本体５１２は、流入口５３を有する第１筐体部５１３と、流出口５５を有する第２筐体部５１４と、の２つの部品によって構成される。第１筐体部５１３は、筐体本体５１２の上側部分を構成する。第２筐体部５１４は、筐体本体５１２の下側部分を構成する。第２筐体部５１４は、第１筐体部５１３に対して着脱可能に取り付けられる。 The drain valve device 5A is different from the drain valve device 5 according to the first embodiment in that it has a housing 51 divided into upper and lower parts. Specifically, the housing body 512 of the housing 51 of the drain valve device 5A is composed of two parts, a first housing portion 513 having an inflow port 53 and a second housing portion 514 having an outlet 55. Will be done. The first housing portion 513 constitutes an upper portion of the housing main body 512. The second housing portion 514 constitutes a lower portion of the housing body 512. The second housing portion 514 is detachably attached to the first housing portion 513.

第１筐体部５１３は、フランジ部５１１から屋外側に向けて突出するとともに、流入口５３よりも鉛直方向の下方に延びている。第１筐体部５１３の下端部５１３ａは、下方に向けて開放している。図１０に示すように、第１筐体部５１３の下端部５１３ａは、排水口２２７の下端の位置よりも鉛直方向の下方に離れて配置される。下端部５１３ａが排水口２２７の下端から下方に離れている高さは、第１の実施形態における排水弁装置５の筐体本体５１２の内底面５１２ａが排水口２２７の下端から離れている高さＨ１に略等しい。 The first housing portion 513 projects from the flange portion 511 toward the outdoor side and extends downward from the inflow port 53 in the vertical direction. The lower end portion 513a of the first housing portion 513 is open downward. As shown in FIG. 10, the lower end portion 513a of the first housing portion 513 is arranged vertically below the position of the lower end portion of the drainage port 227.

It has a valve body portion 522 extending to. The valve body portion 522 has a larger thickness on the tip portion 522a side farther from the rotating shaft portion 521 than on the rotating shaft portion 521 side. As a result, after the end of drainage in which no pressure acts on the drain valve 52 from the indoor side, the tip portion 522a of the drain valve 52 easily moves downward due to its own weight. Therefore, the closed state of the drainage port 227 can be stably maintained, and the effect of preventing air leakage is high.

次に、第３の実施形態に係る排水弁装置６について図１２～図１７を参照して、説明する。図１２及び図１３は、第３の実施形態に係る排水弁装置６を備える引違い窓１Ａを示す。この引違い窓１Ａにおいて、図１及び図２に示した引違い窓１と同一符号の部位は同一構成の部位を示している。そのため、以下の説明において、引違い窓１と重複する説明は省略する。 Next, the drain valve device 6 according to the third embodiment will be described with reference to FIGS. 12 to 17. 12 and 13 show a sliding window 1A provided with the drain valve device 6 according to the third embodiment. In the sliding window 1A, the parts having the same reference numerals as the sliding window 1 shown in FIGS. 1 and 2 indicate parts having the same configuration. Therefore, in the following description, the description overlapping with the sliding window 1 will be omitted.

排水弁装置６は、下枠２２の屋外側壁部２２５に設けられた２つの排水口２２７，２２７にそれぞれ取り付けられる。排水弁装置６は、図１４、図１５及び図１７に示すように、下枠２２の屋外側壁部２２５に対して屋外側から当接する横長矩形状のフランジ部６１と、フランジ部６１に一体に設けられる横長矩形状の排水筒部６２と、排水筒部６２に取り付けられる排水弁６３と、中空部２２２内に配置されるフロート６４と、排水弁６３とフロート６４とを連結する連結部材６５と、を有する。 The drain valve device 6 is attached to two drain ports 227 and 227 provided on the outdoor side wall portion 225 of the lower frame 22, respectively. As shown in FIGS. 14, 15 and 17, the drain valve device 6 is integrated with the horizontally long rectangular flange portion 61 that abuts on the outdoor side wall portion 225 of the lower frame 22 from the outdoor side and the flange portion 61. A horizontally long rectangular drainage cylinder portion 62, a drainage valve 63 attached to the drainage cylinder portion 62, a float 64 arranged in the hollow portion 222, and a connecting member 65 connecting the drainage valve 63 and the float 64. , Have.

フランジ部６１は、下枠２２の屋外側壁部２２５に設けられる排水口２２７の開口面積よりも大きい横長矩形状に形成される。図１４に示すように、フランジ部６１の下側の略半分の領域には、横長矩形状の流出口６１１が開口している。 The flange portion 61 is formed in a horizontally long rectangular shape that is larger than the opening area of the drainage port 227 provided in the outdoor side wall portion 225 of the lower frame 22. As shown in FIG. 14, a horizontally long rectangular outlet 611 is opened in a substantially half region on the lower side of the flange portion 61.

排水筒部６２は、図１５及び図１７に示すように、フランジ部６１の屋内側の側面６１ａから、流出口６１１を取り囲んで屋内側に向けて突出している。排水筒部６２の屋内側の端部６２ａには、中空部２２２と流出口６１１とを連通させる開口部６２１が設けられている。排水筒部６２の外形形状は、下枠２２の屋外側壁部２２５に設けられる排水口２２７の開口形状よりも小さい。そのため、排水筒部６２よりも上方のフランジ部６１の屋内側の側面６１ａには、排水筒部６２と排水口２２７との隙間を埋める段部６１２が、屋内側に向けて突出している。 As shown in FIGS. 15 and 17, the drainage cylinder portion 62 surrounds the outlet 611 and projects toward the indoor side from the side surface 61a on the indoor side of the flange portion 61. The indoor end 62a of the drainage cylinder 62 is provided with an opening 621 for communicating the hollow portion 222 and the outlet 611. The outer shape of the drainage cylinder portion 62 is smaller than the opening shape of the drainage port 227 provided in the outdoor side wall portion 225 of the lower frame 22. Therefore, on the indoor side surface 61a of the flange portion 61 above the drainage cylinder portion 62, a step portion 612 that fills the gap between the drainage cylinder portion 62 and the drainage port 227 projects toward the indoor side.

排水筒部６２及び段部６１２は、図１７に示すように、屋外側から排水口２２７内に挿入される。これによって、排水筒部６２は、開口部６２１及び流出口６１１を介して、中空部２２２の内部と屋外とを連通させている。排水筒部６２の内側以外の排水口２２７は、段部６１２によって封鎖されている。 As shown in FIG. 17, the drainage cylinder portion 62 and the step portion 612 are inserted into the drainage port 227 from the outdoor side. As a result, the drainage cylinder portion 62 communicates the inside of the hollow portion 222 with the outside through the opening 621 and the outlet 611. The drainage port 227 other than the inside of the drainage cylinder portion 62 is closed by the step portion 612.

排水弁６３は、下枠２２の中空部２２２内に配置される排水筒部６２の開口部６２１の屋外側に取り付けられる。詳しくは、排水弁６３は、図１５及び図１６に示すように、下枠２２の延び方向に沿う回転軸部６３１と、回転軸部６３１から下方に延びる矩形板状の弁体部６３２と、を有する。回転軸部６３１は、図１５及び図１７に示すように、開口部６２１の上部に配置される上側爪部６２２及び下側爪部６２３，６２３によって、上下方向から回転可能に挟持される。上側爪部６２２は、開口部６２１の上部中央に配置される。下側爪部６２３，６２３は、開口部６２１の上部の幅方向両端部にそれぞれ配置される。 The drain valve 63 is attached to the outdoor side of the opening 621 of the drainage cylinder portion 62 arranged in the hollow portion 222 of the lower frame 22. Specifically, as shown in FIGS. 15 and 16, the drain valve 63 includes a rotary shaft portion 631 along the extending direction of the lower frame 22, and a rectangular plate-shaped valve body portion 632 extending downward from the rotary shaft portion 631. Has. As shown in FIGS. 15 and 17, the rotary shaft portion 631 is rotatably sandwiched from the vertical direction by the upper claw portion 622 and the lower claw portion 623, 623 arranged above the opening 621. The upper claw portion 622 is arranged in the upper center of the opening 621. The lower claw portions 623 and 623 are arranged at both ends in the width direction of the upper portion of the opening 621, respectively.

排水弁６３は、図１７に示すように、弁体部６３２が回転軸部６３１を中心に屋外側に向けて回転することによって開口部６２１を開放する。これによって、排水口２２７が開放され、中空部２２２と屋外とが連通する。排水弁６３は、弁体部６３２が回転軸部６３１を中心に屋内側に向けて回転することによって開口部６２１を閉鎖する。これによって、排水口２２７が閉鎖され、中空部２２２が屋外に対して封鎖される。 As shown in FIG. 17, the drain valve 63 opens the opening 621 by rotating the valve body portion 632 toward the outdoor side around the rotation shaft portion 631. As a result, the drainage port 227 is opened, and the hollow portion 222 and the outside communicate with each other. The drain valve 63 closes the opening 621 by rotating the valve body portion 632 toward the indoor side around the rotation shaft portion 631. As a result, the drainage port 227 is closed and the hollow portion 222 is closed to the outside.

排水弁６３の回転軸部６３１には、図１５及び図１６に示すように、弁体部６３２が配置される側と反対側に、それぞれ径方向に突出する一対ずつの突部６３３，６３３及び突部６３４，６３４が設けられる。突部６３３，６３３は、排水筒部６２の上側爪部６２２を両側から挟んでいる。これによって、排水弁６３は、横方向の移動が規制され、回転軸部６３１を支点として円滑に開閉可能である。突部６３４，６３４は、排水弁６３が開口部６２１を開放する方向に回転した際に、排水筒部６２の下側爪部６２３、６２３に当接するように配置される。これによって、排水弁６３は、開放方向の過度の回転が規制される。 As shown in FIGS. 15 and 16, the rotary shaft portion 631 of the drain valve 63 has a pair of protrusions 633 and 633 protruding in the radial direction on the side opposite to the side on which the valve body portion 632 is arranged. Protrusions 634,634 are provided. The protrusions 633 and 633 sandwich the upper claw portion 622 of the drainage cylinder portion 62 from both sides. As a result, the drain valve 63 is restricted from moving in the lateral direction, and can be smoothly opened and closed with the rotating shaft portion 631 as a fulcrum. The protrusions 634 and 634 are arranged so as to come into contact with the lower claws 623 and 623 of the drainage cylinder 62 when the drain valve 63 rotates in the direction of opening the opening 621. As a result, the drain valve 63 is restricted from excessive rotation in the opening direction.

図１５及び図１７に示すように、排水筒部６２の屋内側の端部６２ａの下部中央には、上方に向けて突出する突片６２４が設けられる。突片６２４は、開口部６２１を閉鎖する排水弁６３の弁体部６３２の先端に、中空部２２２側から当接する。これよって、突片６２４は、排水弁６３の弁体部６３２が中空部２２２側に過度に入り込むことを防止する。 As shown in FIGS. 15 and 17, a projecting piece 624 projecting upward is provided at the center of the lower portion of the indoor end portion 62a of the drainage cylinder portion 62. The protrusion 624 abuts on the tip of the valve body portion 632 of the drain valve 63 that closes the opening 621 from the hollow portion 222 side. Thereby, the projecting piece 624 prevents the valve body portion 632 of the drain valve 63 from excessively entering the hollow portion 222 side.

フロート６４は、中空円筒体によって構成される。フロート６４の軸方向は、下枠２２の延び方向に沿って横向きに配置される。フロート６４は、図１５及び図１６に示すように、長尺の棒状体からなる一対の連結部材６５，６５によって排水弁６３と連結される。詳しくは、図１６に示すように、排水筒部６２の両側方からはみ出した排水弁６３の回転軸部６３１の両端部に、屋内側に向けて突出する操作腕部６３５，６３５がそれぞれ突設される。操作腕部６３５，６３５の先端には、それぞれ側方に向けて突出する係合軸部６３６，６３６が設けられる。フロート６４の軸方向の両端面には、それぞれ係合軸部６４１，６４１が突設される。連結部材６５，６５の一方の端部６５ａ，６５ａは、操作腕部６３５，６３５の係合軸部６３６，６３６に対して、それぞれ回転可能に緩く係合している。連結部材６５，６５の他方の端部６５ｂ，６５ｂは、フロート６４の係合軸部６４１，６４１に対して、それぞれ回転可能に緩く係合している。 The float 64 is composed of a hollow cylinder. The axial direction of the float 64 is arranged laterally along the extending direction of the lower frame 22. As shown in FIGS. 15 and 16, the float 64 is connected to the drain valve 63 by a pair of connecting members 65, 65 made of a long rod-shaped body. Specifically, as shown in FIG. 16, operating arm portions 635 and 635 protruding toward the indoor side are projected from both ends of the rotary shaft portion 631 of the drain valve 63 protruding from both sides of the drainage cylinder portion 62, respectively. Will be done. At the tips of the operating arm portions 635 and 635, engaging shaft portions 636 and 636 protruding laterally are provided, respectively. Engagement shaft portions 641 and 641 are projected from both end faces in the axial direction of the float 64, respectively. One end 65a, 65a of the connecting members 65, 65 is rotatably and loosely engaged with the engaging shaft portions 636, 636 of the operating arm portions 635 and 635, respectively. The other ends 65b, 65b of the connecting members 65, 65 are rotatably and loosely engaged with the engaging shaft portions 641, 641 of the float 64, respectively.

フロート６４は、排水筒部６２の上方に配置される。フロート６４は、中空であるため、図１７に示すように、下枠２２の中空部２２２内の水位の上昇に伴って、浮力によって上昇する。フロート６４が上昇すると、連結部材６５，６５が操作腕部６３５，６３５を上動させ、排水弁６３の回転軸部６３１を回転させる。これによって、排水弁６３は、開口部６２１を開放し、中空部２２２内の水を屋外に排出する。 The float 64 is arranged above the drainage cylinder portion 62. Since the float 64 is hollow, as shown in FIG. 17, the float 64 rises due to buoyancy as the water level in the hollow portion 222 of the lower frame 22 rises. When the float 64 rises, the connecting members 65 and 65 move the operating arm portions 635 and 635 upward to rotate the rotary shaft portion 631 of the drain valve 63. As a result, the drain valve 63 opens the opening 621 and drains the water in the hollow portion 222 to the outside.

このように、第３の実施形態に係る排水弁装置６は、下枠２２に開口する排水口２２７を開閉可能に設けられる排水弁６３と、下枠２２の内部に配置されるフロート６４と、排水弁６３とフロート６４とを連結する連結部材６５，６５と、を備える。連結部材６５，６５は、下枠２２の内部の水位の上昇に伴ってフロート６４が上昇した際に、排水弁６３を開放するように連結される。そのため、下枠２２の中空部２２２内に水が溜まって水位が上昇した際に、排水弁６３を確実に開放動作させることができる。これによって、排水弁装置６は、下枠２２の大きさに関係なく、下枠２２の中空部２２２の排水性能を向上させることができる。 As described above, the drain valve device 6 according to the third embodiment includes a drain valve 63 provided so as to be able to open and close the drain port 227 opening in the lower frame 22, and a float 64 arranged inside the lower frame 22. The connecting members 65 and 65 for connecting the drain valve 63 and the float 64 are provided. The connecting members 65 and 65 are connected so as to open the drain valve 63 when the float 64 rises with the rise of the water level inside the lower frame 22. Therefore, when water accumulates in the hollow portion 222 of the lower frame 22 and the water level rises, the drain valve 63 can be reliably opened. Thereby, the drain valve device 6 can improve the drainage performance of the hollow portion 222 of the lower frame 22 regardless of the size of the lower frame 22.
