Description

【0001】
【発明の属する技術分野】
本発明は、洋式便器に関するものである。
【0002】
【従来の技術】
近年、アパートやマンションなどの高層集合住宅では、深夜、トイレで小便をした際に発生する小便行為音が階下の住人に不快感を与えたり、日本家屋で玄関近くにトイレを設置する例が多いが、来客時に行為者が気になるなどの問題がある。
【0003】
図10は従来の洋式便器の斜視図である。図において、aは便器である。便器aは床hに、図示しないボルトにより取り付けられている。bは便座、cは便蓋、dは給水タンク、eは手洗い用水栓である。fは給水管、gは便座bを温めるための給電用コードである。
【0004】
上記小便行為音とは、小便が便器a内の貯水面に衝突した時に発生する音である。小便が便器a内の貯水面に衝突すると便器aを振動し、その振動が床hを伝搬して固体伝搬する。固体伝搬音は、便器aが、図示しないボルトによって床hに取り付けられているため、便器aの下面と床hの上面との接触部およびボルト取り付け部から床hを通して階下へ発生する。なお、この小便行為音によって不快感を生じる周波数は、約250Hz〜4kHzである。
【0005】
上記固体伝搬音の低減対策としては、たとえば、便器aの下面と床hの上面との接触部に、厚さ5mm程度のゴムシートiを設けて防音支持する方法がある。(No.104/dec.1998 音響技術 P43)
【0006】
【発明が解決しようとする課題】
しかし、従来のゴムシートを設けて防音支持する方法は、固体音の伝搬減少対策であり、小便行為の音を直接低減するものではなく、効果も限られたものであった。
【0007】
本発明は、従来技術のかかる問題点に鑑み案出したもので、便器内の水面に気泡を分布させることによって小便が水面と衝突する際の衝撃音の低減を図るとともに、衝突の際に水中に巻き込まれた気泡の固有振動による水中放射音の加振力を水中気泡の遮蔽効果により低減させ、便器固体音の低減を図るようにした洋式便器を提供することを目的とする。
【0008】
【課題を解決するための手段】
上記目的を達成するため、本願請求項1記載発明の洋式便器は、汚物を受けるボウル部と、該ボウル部の下端に接続され、ボウル部内に一定の水位を保つトラップ部とを有する洋式便器において、上記ボウル部の内面の上記水面よりも下方に開口を設け、ボウル部内の水中に気泡を放出して水面に気泡を分布させる気泡発生装置を設けるとともに、該気泡発生装置に空気を供給する送風機を接続したものである。
【0009】
また、本願請求項2記載発明の洋式便器は、汚物を受けるボウル部と、該ボウル部の下端に接続され、ボウル部内に一定の水位を保つトラップ部と、給水タンクとを有する洋式便器において、ボウル部の内面の上記水面よりも下方に開口を設け、該開口に一端を給水タンクに接続した給水管を接続し、該給水管の中間に給水ポンプと圧力調整弁とを設け、かつ、その下流側に気泡発生装置を設け、ボウル部内の水中に気泡の混入した水を放出して水面に気泡を分布させるとともに、該気泡発生装置に空気を供給する送風機を接続したものである。
【0010】
給水タンクに接続した給水ポンプに替えて水道管に圧力調整弁を設け、その下流側に気泡発生装置を設けてもよい。
【0011】
気泡発生装置は、多数の微細な気孔を有する分散板を有してなるのが好ましい。
【0012】
次に本発明の作用を説明する。小便をするためトイレに入り、まず送風機作動用のスイッチを入れる。スイッチが入ると直ちに送風機が作動して、便器の内面の水位よりも下方に設けた気泡発生装置から便器のボウル部内の水中に向けて気泡を放出する。水中に放出された気泡は、浮力によって上昇して水面に一様に分布して盛り上がる。小便が終わり便器中の小便を流し、送風機作動用のスイッチを切ってトイレから出る。
【0013】
このように、便器に小便をする際、ボウル部内の水中に気泡を放出して水面に気泡を分布する気泡発生装置と、該気泡発生装置に空気を供給する送風機とを設けたので、小便をする際、便器内の水面に気泡を分布させる。水面には気泡が盛り上がっているので、小便が水面と衝突する際に気泡が緩衝材となって小便行為音(衝撃音)の低減を図ることができる。また、衝突の際に水中に巻き込まれた気泡の固有振動による水中放射音は、水中気泡の遮蔽効果により固体音の原因となる加振力が低減し、便器の固体音の低減を図ることがきる。
【0014】
【発明の実施の形態】
以下、本発明の一実施形態について図面を参照しつつ説明する。図1は本願請求項1記載発明の洋式便器の側断面図である。図2は気泡発生装置の拡大斜視図である。図において、1は洋式便器である。2は洋式便器1の汚物を受けるボウル部である。2aはボウル部2の内面である。2bは内面2aのボウル部2内の水位よりも下方に設けた開口である。本図ではトラップ部3を形成するため、貯水7中に垂下して壁部2cの下端近傍に設けてある。トラップ部3は、ボウル部2の下端に接続され、ボウル部2内に一定の水位を保つ。4は給水管で、一端を給水タンクに接続し、他端をボウル部2の上縁に設けられた洗浄水通路5に接続している。7aは便器1内の貯水7の水位(水面)である。8はトラップ部3の下流側に接続された排水管である。9は内面2aの開口2bに設けた気泡発生装置である。11は小型の送風機(コンプレッサ)で、空気供給管12を介して気泡発生装置9に空気を送る。圧力は0.2Mpa程度である。14は小便の落下方向を示す矢印である。15は便座、16は便蓋である。

気泡発生装置9は、図2に示すように、たとえば、アルミ製などの耐圧容器9aとその内部に設けた多数の微細な気孔を有する分散板10を有している。分散板10は、濾過フィルタなどに使用される多孔質板で、セラミックスまたは金属の焼結板である。気泡発生装置9は、送風機11から空気供給管12を介して送られた空気によって便器1のボウル部2内の貯水7の水面7aに向けて多数の気泡13を放出する。気泡13は放出されると水中7を上昇し、水面7aに一様に拡がり泡13aとなって盛り上がる。
【0016】

【0017】
図4は本願請求項3記載発明の洋式便器の部分側面図である。図4は図3に示した給水タンク6に接続した給水ポンプ21に替えて水道管20Aに遮断弁を兼ねた圧力調整弁22を設け、その下流側に気泡発生装置9を設けたものである。他の構成は、図3に示すものと同じであり、説明を省略する。
【0018】
次に本実施形態の作用を説明する。便器1のボウル部2の内面2aの水位(水面)7aよりも下方に、小便をする際、ボウル部2内の貯水7の水面7aに向けて気泡13を放出する気泡発生装置9と、該気泡発生装置9に空気を供給する送風機11とを設けて、小便をする際、ボウル部2内の貯水7の水面7aに泡13aを分布させる。それにより小便が水面7aと衝突する際の小便行為音(衝撃音)の低減を図るとともに、衝突の際に水中7に巻き込まれた気泡13の固有振動による水中放射音を水中気泡13の遮蔽効果により便器1への加振力を低減させ便器1の固体音の低減を図ることができる。
【0019】

【0021】
図7および図8は気泡サイズ密度分布図である。図7および図8は、図6に示す写真から計測した気泡サイズの密度の分布を示すもので、共に横軸に気泡の半径(mm)を示している。図7は縦軸に体積当たりの気泡の個数((個)/m)を示しており、図8は写真から計測した気泡の個数(1225個)について半径の分布を示している。

図9は気泡層を挟んで音源と音の計測器を配置して計測した透過損失を示す図である。横軸に周波数(dB)を、縦軸に透過損失(kHz)を示している。0線よりも下方(+)に減衰量を示している。図中、線Aは図7、図8に示す気泡発生装置における遮音効果(透過損失)の実験結果を示し、図中、線Bは次式で示す式から得られた結果を示している。なお、ハッチング部分は遮音効果領域である。
【0023】
一般に水中気泡の大きさと遮音周波数とは、次式に示す関係にある。
【0024】
=3.25×10/a
:気泡における遮音周波数(Hz)
a:気泡の半径(μm)
【0025】
図9からわかるように、本実験に用いた分散板では気泡の半径が0.08〜0.15mmの領域に多く分布しているため、遮音効果が高い周波数が20kHz〜60kHzである。小便行為音で遮音したいのは、先に述べたように250Hz〜4kHzなので、気泡のサイズが小さ過ぎることがわかる。上記計算式から分散板は、半径13mm(250Hz)〜0.8mm(4kHz)の気泡を多く発生させるものであるのが好ましい。
【0026】
本発明は以上述べた実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。
【0027】
【発明の効果】
以上述べたように、本発明の洋式便器は、便器内の水面に気泡を分布させることによって小便が水面と衝突する際の衝撃音の低減を図るとともに、衝突の際に水中に巻き込まれた気泡の固有振動による水中放射音の加振力を水中気泡の遮蔽効果により低減させ、便器の固体音の低減を図ることができるという優れた効果を奏する。

The toilet a is attached to the floor h by bolts (not shown). b is a toilet seat, c is a toilet lid, d is a water tank, and e is a hand-washing faucet. f is a water supply pipe, g is a power supply cord for warming the toilet seat b.
[0004]
The urine action sound is a sound generated when urine collides with a water storage surface in the toilet a. When the urine collides with the water storage surface in the toilet a, the toilet a vibrates, and the vibration propagates through the floor h and propagates through the solid. Since the toilet bowl a is attached to the floor h by bolts (not shown), the solid-borne sound is generated downstairs through the floor h from the contact portion between the lower surface of the toilet a and the upper surface of the floor h and the bolt attachment part. The frequency at which discomfort is caused by the urination sound is about 250 Hz to 4 kHz.
[0005]
As a countermeasure for reducing the solid-borne noise, for example, there is a method in which a rubber sheet i having a thickness of about 5 mm is provided at a contact portion between the lower surface of the toilet a and the upper surface of the floor h for soundproofing. (No.104 / dec. 1998 Sound Technology P43)
[0006]
[Problems to be solved by the invention]
However, the conventional method of providing soundproofing by providing a rubber sheet is a measure for reducing the propagation of solid sound, and does not directly reduce the sound of urination, but has a limited effect.
[0007]
The present invention has been devised in view of the above-described problems of the related art, and aims to reduce the impact sound when urine collides with the water surface by distributing bubbles on the water surface in the toilet bowl, and to reduce the impact sound when the collision occurs. It is an object of the present invention to provide a Western-style toilet in which the exciting force of underwater radiated sound due to the natural vibration of bubbles entrained in the toilet is reduced by the shielding effect of the underwater bubbles, thereby reducing the solid sound of the toilet.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the western style toilet according to the first aspect of the present invention is a western style toilet having a bowl portion for receiving waste and a trap portion connected to a lower end of the bowl portion and maintaining a constant water level in the bowl portion. A blower for providing an opening below the water surface on the inner surface of the bowl portion, providing a bubble generator for releasing bubbles into the water in the bowl portion and distributing the bubbles on the water surface, and supplying air to the bubble generator. Are connected.
[0009]
Further, the Western style toilet according to the second aspect of the present invention is a Western style toilet having a bowl portion for receiving waste, a trap portion connected to a lower end of the bowl portion and maintaining a constant water level in the bowl portion, and a water supply tank, An opening is provided below the water surface on the inner surface of the bowl portion, a water supply pipe having one end connected to a water supply tank is connected to the opening, and a water supply pump and a pressure regulating valve are provided in the middle of the water supply pipe, and An air bubble generator is provided on the downstream side, and water mixed with air bubbles is released into the water in the bowl portion to distribute the air bubbles on the water surface, and a blower for supplying air to the air bubble generator is connected.
[0010]
Instead of the water supply pump connected to the water supply tank, a pressure adjusting valve may be provided in the water pipe, and a bubble generator may be provided downstream of the pressure adjusting valve.

[0016]
FIG. 3 is a side sectional view of the Western style toilet according to the second aspect of the present invention. In the figure, portions common to those described in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description will be omitted. In the figure, reference numeral 20 denotes a water supply pipe having one end connected to the water supply tank 6 and the other end connected to an opening 2b provided below the water level (water surface) 7a in the bowl 2 on the inner surface 2a of the bowl 2.

Thereby, while reducing urine action sound (impact sound) when the urine collides with the water surface 7a, the underwater radiated sound due to the natural vibration of the air bubble 13 entrained in the water 7 at the time of the collision is shielded by the underwater air bubble 13. Accordingly, the exciting force applied to the toilet 1 can be reduced, and the solid sound of the toilet 1 can be reduced.
[0019]
【Example】
Next, experimental results for verifying the effects of the present invention will be described. The experiment was performed using a water tank. FIG. 5 is a diagram showing an experimental state of measurement of sound insulation characteristics by an air layer in a water tank. A pedestal 17 is set in a water tank (not shown), and the bubble generator 9 is placed on the pedestal 17 to remove air. Air was sent from the supply pipe 12, and the air bubbles 13 were generated in a film form from the upper surface of the bubble generator 9 with the upper surface of the dispersion plate 10 of the bubble generator 9 facing upward.
[0020]
FIG. 6 is an enlarged photograph showing the distribution of bubbles during the experiment. The number and radius of bubbles were measured from this photograph.
[0021]
7 and 8 are bubble size density distribution diagrams. 7 and 8 show the distribution of bubble size densities measured from the photograph shown in FIG. 6, and the horizontal axis shows the radius (mm) of bubbles. FIG. 7 shows the number of air bubbles per volume ((number) / m 3 ) on the vertical axis, and FIG. 8 shows the distribution of radii for the number of air bubbles (1225) measured from the photograph.
[0022]
FIG. 9 is a diagram showing transmission loss measured by arranging a sound source and a sound measuring device with a bubble layer interposed therebetween. The horizontal axis indicates frequency (dB), and the vertical axis indicates transmission loss (kHz). The amount of attenuation is shown below (+) the line 0. In the figure, line A shows the experimental result of the sound insulation effect (transmission loss) in the bubble generator shown in FIGS. 7 and 8, and in the figure, line B shows the result obtained from the following equation. The hatched portion is a sound insulation effect area.
[0023]
In general, the size of bubbles in water and the sound insulation frequency have the relationship shown in the following equation.
[0024]
f b = 3.25 × 10 6 / a
f b : sound insulation frequency of bubbles (Hz)
a: radius of bubble (μm)
[0025]
As can be seen from FIG. 9, in the dispersion plate used in this experiment, the radius of the bubbles is largely distributed in the region of 0.08 to 0.15 mm, and therefore, the frequency at which the sound insulating effect is high is 20 kHz to 60 kHz. Since it is 250 Hz to 4 kHz as described above that the user wants to be insulated by the urination sound, it can be seen that the size of the bubble is too small. From the above formula, it is preferable that the dispersion plate generates a lot of bubbles having a radius of 13 mm (250 Hz) to 0.8 mm (4 kHz).
[0026]
The present invention is not limited to the embodiments described above, and various changes can be made without departing from the gist of the invention.
[0027]
【The invention's effect】
