Description

本発明は、洗面ボウルから排水が溢れ出すことを防止するオーバーフロー装置に関する。また、本発明は、斯かるオーバーフロー装置を備える洗面器装置に関する。   The present invention relates to an overflow device that prevents drainage from overflowing from a wash bowl. The present invention also relates to a basin device provided with such an overflow device.

洗面器装置等には、洗面ボウルの満水時に更に給水が行われた場合に、洗面ボウルから水が溢れ出すことを防止するために、オーバーフロー装置が取設される。しかしながら、オーバーフロー装置の排水能力が不足して、洗面ボウルから水が溢れ出すことがある。   An overflow device is installed in the wash basin device or the like in order to prevent water from overflowing from the wash bowl when water is further supplied when the wash bowl is full. However, the drainage capacity of the overflow device is insufficient, and water may overflow from the wash bowl.

この問題を解決するものとして、槽体内側壁に開口したオーバーフロー口に連通する取水口を有した箱体と、該箱体の下壁に前記取水口と連通するように開口した排出口とから成るオーバーフロー装置であり、前記排出口内周面と前記箱体の後壁及び左右のサイド壁とを、ある程度の距離を設けて隔設したオーバーフロー装置が提案されている（例えば、特許文献１参照。）。   As a solution to this problem, it comprises a box body having a water intake port communicating with the overflow port opened in the side wall of the tank body, and a discharge port opened so as to communicate with the water intake port on the lower wall of the box body. An overflow device that is an overflow device in which the inner peripheral surface of the discharge port is separated from the rear wall and the left and right side walls of the box by a certain distance has been proposed (see, for example, Patent Document 1). .

このオーバーフロー装置によれば、箱体内の水流が後壁と排水口との間を渦の水流を形成しつつ通過するので、渦によって空気抜きができ、乱流が発生せず排水スピードを向上させることができる。   According to this overflow device, since the water flow in the box passes between the rear wall and the drainage port while forming a vortex flow, air can be vented by the vortex, and turbulent flow does not occur and the drainage speed is improved. Can do.

しかしながら、排出口内周面と箱体の後壁とを、ある程度の距離を設けて隔設する（箱体の奥行きを大きくする）ことには、以下の問題がある。   However, separating the inner peripheral surface of the discharge port and the rear wall of the box with a certain distance (increasing the depth of the box) has the following problems.

通常洗面ボウルは左右対称に形成され、その対称軸上に水栓が取り付けられ、オーバーフロー口も対称軸上に、そして、水栓が設けられた上面の前面側壁に開口される。ということは、図４（ａ）及び（ｂ）に示すように、オーバーフロー装置１０１の箱体１０２の背後には、水栓１０３に接続される配水管１０４が位置することになる。したがって、このままでは、箱体１０２の奥行きを大きくするスペース上の余裕はない。   Usually, the wash bowl is formed symmetrically, a faucet is attached on the axis of symmetry, the overflow port is also opened on the axis of symmetry, and is opened on the front side wall on the upper surface provided with the faucet. That is, as shown in FIGS. 4A and 4B, the water distribution pipe 104 connected to the faucet 103 is located behind the box 102 of the overflow device 101. Therefore, there is no room on the space for increasing the depth of the box 102 as it is.

配水管１０４の前に奥行きの大きな箱体１０２を配置するには、図４（ｃ）に示すように、洗面ボウル１００を手前に移動させるか、洗面ボウル１００を小さくするかして、オーバーフロー口１０５と配水管１０４との間にスペースを設ける必要がある。   In order to arrange the box 102 having a large depth in front of the water distribution pipe 104, as shown in FIG. 4 (c), the wash bowl 100 is moved forward or the wash bowl 100 is made small, and the overflow port is formed. It is necessary to provide a space between 105 and the water distribution pipe 104.

しかしながら、前者は使用者が立つ洗面スペースを狭くしたり、洗面台自体の奥行きを大きくしてしまう。後者は洗面ボウル１００の容量が小さくなる。また、いずれにしても、水栓１０３自体を長くしなければならない。そこで、図５に示すように、オーバーフロー口１０５位置を対称軸上からずらすことも考えられるが、これは意匠上美しいとはいえない。   However, the former narrows the wash space where the user stands and increases the depth of the washstand itself. In the latter case, the capacity of the wash bowl 100 is reduced. In any case, the faucet 103 itself must be lengthened. Therefore, as shown in FIG. 5, it is conceivable to shift the position of the overflow port 105 from the axis of symmetry, but this is not beautiful in design.

また、排出口内周面と箱体の左右のサイド壁とを、ある程度の距離を設けて隔設する（箱体の幅を大きくする）ことにも、以下の問題がある。   In addition, there is the following problem in separating the inner peripheral surface of the discharge port and the left and right side walls of the box with a certain distance (increasing the width of the box).

まず、箱体の幅を大きくすれば、取水口の周囲が長くなり、これに伴い、オーバーフロー口と取水口との間に挟装されるパッキンも長くなり、これをオーバーフロー口及び取水口に密着させるために、ビスを追加する必要が生じる等水密性の確保が大変になる。   First, if the width of the box is increased, the circumference of the intake port becomes longer, and accordingly, the packing sandwiched between the overflow port and the intake port also becomes longer, and this is closely attached to the overflow port and the intake port. Therefore, it is necessary to add screws to ensure watertightness.

また、図６に示すように、洗面ボウル１００が平面視円状の場合等、洗面ボウルの形状によっては、部分的に厚肉の部分１００ａが生じ、この部分だけ色調や艶が異なって外観不良が生じる。特に薄肉の洗面ボウル１００の場合、厚肉部１００ａの範囲が広くなって、この問題は顕著になる。   In addition, as shown in FIG. 6, depending on the shape of the wash bowl, such as when the wash bowl 100 is circular in plan view, a thick portion 100a is produced partially, and only this portion has a different color tone and gloss, resulting in poor appearance. Occurs. In particular, in the case of the thin wash bowl 100, the range of the thick part 100a becomes wide, and this problem becomes remarkable.

洗面ボウル１００に厚肉部分１００ａを設けず、箱体１０２の形状を洗面ボウル１００に合わせることもできるが、洗面ボウル毎に箱体の形状を変えなければならず、汎用性に欠ける。   It is possible to match the shape of the box 102 with the wash bowl 100 without providing the thick wall portion 100a in the wash bowl 100, but the shape of the box must be changed for each wash bowl, which lacks versatility.

本発明は、上述した事情を考慮してなされたもので、取水口部分の奥行きや幅を大きくすることなく、排水速度を向上させ、洗面ボウル内の水が洗面ボウルから溢れることのないオーバーフロー装置及び斯かるオーバーフロー装置を備える洗面器装置を提供することを目的とするものである。   The present invention has been made in consideration of the above-described circumstances, and improves the drainage speed without increasing the depth and width of the water intake portion, so that the water in the wash bowl does not overflow from the wash bowl. And it aims at providing a washbasin apparatus provided with such an overflow apparatus.

本発明に係るオーバーフロー装置は、上述した課題を解決するために、洗面ボウル内面に開口したオーバーフロー口に連通する取水口部と、上端が該取水口に連通し、上記取水口部より幅方向が拡大し断面積が大きくなった拡大空間部と、上記洗面ボウル底部に開口した排水口に連通する排水口部と、上記拡大空間部下端に開口した排水口と上記排水口部とを連通する導水管部とを備え、上記拡大空間部は、上記取水口部より下方に配置されているものである。   In order to solve the above-described problem, the overflow device according to the present invention has a water intake port portion that communicates with an overflow port that is open on the inner surface of the wash bowl, and an upper end that communicates with the water intake port, and the width direction is greater than that of the water intake port portion. An enlarged space portion having an enlarged cross-sectional area, a drain port portion communicating with a drain port opened at the bottom of the wash bowl, a drain port opening at the lower end of the enlarged space portion, and a guide port communicating the drain port portion. A water pipe part, and the expansion space part is disposed below the water intake part.

そして、前記取水口部は、好適には、前記洗面ボウルの取付面と平行となるように水平方向に長く形成され、前記拡大空間部は、好適には、前記洗面ボウルの取付面と平行となるように水平方向に長く形成されることが望ましい。また、前記取水口部と前記拡大空間部の奥行きは、好適には、同一であることが望ましい。   The water intake portion is preferably formed long in the horizontal direction so as to be parallel to the attachment surface of the wash bowl, and the enlarged space portion is preferably parallel to the attachment surface of the wash bowl. It is desirable to be formed long in the horizontal direction. Moreover, it is desirable that the depths of the intake port and the expansion space are preferably the same.

他方、上述した課題を解決するために、洗面ボウル内面に開口したオーバーフロー口と、洗面ボウル底部に開口した排水口と、上記オーバーフロー口と上記排水口とを連通するオーバーフロー装置とを備える洗面器装置であって、上記オーバーフロー装置は、上記オーバーフロー口に連通する取水口部と、上端が該取水口に連通し、上記取水口部より幅方向が拡大し断面積が大きくなった拡大空間部と、上記排水口に連通する排水口部と、上記拡大空間部下端に開口した排水口と上記排水口部とを連通する導水管部とを備え、上記拡大空間部は、上記取水口部より下方に配置されているものである。   On the other hand, in order to solve the above-mentioned problem, a basin device comprising an overflow port opened on the inner surface of the wash bowl, a drain port opened on the bottom of the wash bowl, and an overflow device communicating the overflow port and the drain port The overflow device includes a water intake port portion that communicates with the overflow port, an upper end portion that communicates with the water intake port, an enlarged space portion whose width direction is larger than that of the water intake port portion, and a cross-sectional area is increased. A drain port portion communicating with the drain port, a drain port opened at a lower end of the enlarged space portion, and a conduit pipe portion communicating the drain port portion, wherein the enlarged space portion is provided below the intake port portion. It is what is arranged.

本発明に係るオーバーフロー装置及び斯かるオーバーフロー装置を備える洗面器装置によれば、取水口部分の奥行きや幅を大きくすることなく、排水速度を向上させ、洗面ボウル内の水が洗面ボウルから溢れることはないという効果が得られる。   According to the overflow device according to the present invention and the basin device provided with such an overflow device, the drainage speed is improved without increasing the depth and width of the water intake portion, and the water in the wash bowl overflows from the wash bowl. The effect that there is no.

本発明に係るオーバーフロー装置及び斯かるオーバーフロー装置を備える洗面器装置の実施の形態について、添付図面を参照して説明する。図１は、本発明に係る洗面器装置１の一実施形態を示す図で、（ａ）は背面図、（ｂ）は（ａ）におけるＡ−Ａ断面図である。また、図２は、図１（ｂ）の要部を拡大したものである。   Embodiments of an overflow device according to the present invention and a basin device provided with such an overflow device will be described with reference to the accompanying drawings. Drawing 1 is a figure showing one embodiment of washbasin device 1 concerning the present invention, (a) is a rear view, and (b) is an AA sectional view in (a). FIG. 2 is an enlarged view of the main part of FIG.

本実施形態に係る洗面器装置１は、洗面ボウル２と、洗面ボウル２の底部に設けられた排水口３と洗面ボウル２の側面上縁寄りに開口したオーバーフロー口４とを連通するオーバーフロー装置１０とから構成される。   The basin apparatus 1 according to the present embodiment includes an overflow apparatus 10 that communicates a basin 2 with a basin 2, a drain port 3 provided at the bottom of the basin bowl 2, and an overflow port 4 that opens near the upper side edge of the basin 2. It consists of.

オーバーフロー装置１０は、洗面ボウル２のオーバーフロー口４に水密に接続される取水口部１１と、上端がこの取水口部１１に連通し、取水口部１１より幅方向が拡大し断面積が大きくなった拡大空間部１２と、洗面ボウル２の排水口３に水密に接続される排水口部１４とを備え、拡大空間部１２下端に開口した排水口１２ａと排水口部１４とは、導水管部１３により連接される。   The overflow device 10 has a water intake port 11 that is watertightly connected to the overflow port 4 of the wash bowl 2 and an upper end that communicates with the water intake port 11. The width direction is larger than that of the water intake port 11 and the cross-sectional area is increased. The expanded space portion 12 and a drain port portion 14 that is connected to the drain port 3 of the wash bowl 2 in a watertight manner, and the drain port 12a and the drain port portion 14 that are open at the lower end of the expanded space portion 12 13 are connected.

取水口部１１及び拡大空間部１２は、本実施形態に示す例では、図３に示すように一体に形成されている。   In the example shown in this embodiment, the water intake port 11 and the enlarged space portion 12 are integrally formed as shown in FIG.

取水口部１１は、洗面ボウル２のオーバーフロー口４と連通する開口ＯＰと、この開口ＯＰ周りに取着され、オーバーフロー口４と取水口部１１との間の水密性を確保するリング状のパッキン１１ａと、取水口部１１を洗面ボウル２にねじ止めするためのビス孔１１ｂとを備える。   The water intake port 11 has an opening OP that communicates with the overflow port 4 of the wash bowl 2 and a ring-shaped packing that is attached around the opening OP and ensures water tightness between the overflow port 4 and the water intake port 11. 11 a and a screw hole 11 b for screwing the water intake port 11 to the wash bowl 2.

この開口ＯＰの大きさは、従来のオーバーフロー装置のものと同じ大きさであり、取水口部１１は洗面ボウル２の取付面と平行となるように水平方向に長く形成されている。したがって、この取水口部１１は従来の洗面ボウルに取付可能であり、汎用性を有する。   The size of the opening OP is the same as that of the conventional overflow device, and the water intake 11 is formed long in the horizontal direction so as to be parallel to the mounting surface of the wash bowl 2. Therefore, the water intake 11 can be attached to a conventional wash bowl and has versatility.

また、開口ＯＰの周囲の長さも従来と同じなので、オーバーフロー口４と取水口部１１との間に挟装されるパッキン１１ａの長さも従来のものと等しく、これをオーバーフロー口４及び取水口部１１に密着させるために、ビスを追加する等の必要性も生じない。   Further, since the length of the periphery of the opening OP is the same as the conventional one, the length of the packing 11a sandwiched between the overflow port 4 and the water intake port portion 11 is the same as that of the conventional one, which is the overflow port 4 and the water intake port portion. Therefore, it is not necessary to add screws or the like.

さらに、洗面ボウル２が平面視円状の場合等であっても、特段厚肉の部分が生じないので、一部分だけ色調や艶が異なって外観不良が生じるということもない。   Furthermore, even when the wash bowl 2 is circular in plan view, no particularly thick portion is produced, so that only a part of the color tone or gloss is different, and an appearance defect does not occur.

拡大空間部１２は、取水口部１１より幅方向のみが拡大し、奥行き方向は、導水管部１３と略同一である。このように、奥行き方向には拡大しないので、背面に水栓に接続される給水管があっても、干渉することはない。拡大空間部１２は、洗面ボウル２の取付面と平行となるように水平方向に長く形成されている。拡大空間部１２の幅方向は、その下端において狭窄し、導水管部１３と連通可能な排水口１２ａが形成される。   Only the width direction of the expansion space portion 12 is larger than that of the water intake port portion 11, and the depth direction is substantially the same as the water conduit portion 13. Thus, since it does not expand in the depth direction, even if there is a water supply pipe connected to the faucet on the back side, there is no interference. The enlarged space portion 12 is formed long in the horizontal direction so as to be parallel to the mounting surface of the wash bowl 2. The width direction of the enlarged space portion 12 is narrowed at the lower end thereof, and a drain port 12a that can communicate with the water conduit portion 13 is formed.

本実施の形態に係る洗面器装置１は上記のように構成されており、以下その排水作用について説明する。   The basin apparatus 1 according to the present embodiment is configured as described above, and the drainage action will be described below.

洗面ボウル２の排水口３を閉塞した状態で洗面ボウル２に水を溜め、水位がオーバーフロー口４の下縁を超えると、水はオーバーフロー装置１０の取水口部１１へと流れ出す。   When water is accumulated in the wash bowl 2 with the drain port 3 of the wash bowl 2 closed, and the water level exceeds the lower edge of the overflow port 4, the water flows out to the water intake 11 of the overflow device 10.

取水口部１１から流入した水は拡大空間部１２へと導かれ、この拡大空間部１２にある程度水が溜まると、排水口１２ａ直上部分の水は重力により落下するから、それ以外の部分の内部に、排水口１２ａ直上部分に対する水頭差に対応する吸引力、すなわち、サイフォン力が発生する。   The water flowing in from the water intake port 11 is guided to the enlarged space portion 12, and when water is accumulated in the enlarged space portion 12 to some extent, the water immediately above the drain port 12a falls due to gravity, so the inside of the other portions In addition, a suction force corresponding to the water head difference with respect to the portion directly above the drain port 12a, that is, a siphon force is generated.

排水口１２ａ直上部分以外の水は、サイフォン力によって排水口１２ａ直上部分に向かって吸引され、導水管１３内が水で満たされる所謂満流流れとなって導水管１３内を排水口部１４に向かって流下する。拡大空間部１２内におけるサイフォン力の発生およびそれに引き続く満流流れの発生を、サイフォン現象という。   Water other than the portion directly above the drain port 12a is sucked by the siphon force toward the portion immediately above the drain port 12a, forming a so-called full flow in which the inside of the water conduit 13 is filled with water. Flow down. The generation of siphon force in the enlarged space portion 12 and the subsequent generation of full flow are called siphon phenomenon.

このように、拡大空間部１２においてはサイフォン現象が発生しやすくなり、排水速度が向上するので、拡大空間部１２を有しない従来のオーバーフロー装置のように、排水能力が不足して、洗面ボウルから水が溢れ出すことはない。   Thus, the siphon phenomenon is likely to occur in the enlarged space portion 12 and the drainage speed is improved, so that the drainage capacity is insufficient as in the conventional overflow device that does not have the enlarged space portion 12, and the wash bowl is removed. The water will not overflow.

他方、洗面ボウル２の排水口３を閉塞した状態で洗面ボウル２に水を溜め、その後排水口３を開放すると、大量の水が一気に排水口部１４に流れ込むため、排水の一部が一時的に導水管１３を逆流することがある。   On the other hand, if water is stored in the wash bowl 2 with the drain port 3 of the wash bowl 2 closed, and then the drain port 3 is opened, a large amount of water flows into the drain port portion 14 at a stretch, so that part of the drainage is temporarily The water guide pipe 13 may flow backward.

この水は、従来のオーバーフロー装置であれば、オーバーフロー口４から洗面ボウル２内に噴出する、或いは噴出には至らないものの、オーバーフロー口４内部に水が見えるという問題が発生する。   If this water is a conventional overflow device, it will be ejected into the wash bowl 2 from the overflow port 4 or it will not be ejected, but there will be a problem that water can be seen inside the overflow port 4.

しかしながら、本発明に係るオーバーフロー装置１０によれば、逆流した水は拡大空間部１２に滞留するので、そのような事態は生じない。   However, according to the overflow device 10 according to the present invention, the backflowed water stays in the enlarged space portion 12, so that such a situation does not occur.

以上に説明した実施態様は説明のためのものであり、本発明の範囲を制限するものではない。したがって、当業者であればこれらの各要素もしくは全要素をこれと均等なものによって置換した実施態様を採用することが可能であるが、これらの実施態様も本発明の範囲に含まれる。   The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, but these embodiments are also included in the scope of the present invention.
