Description

小便器urinal
　本発明は、小便器に関するものである。 The present invention relates to a urinal.
　特許文献１は従来の小便器を開示している。この小便器は、便鉢部を有する小便器本体と、便鉢部の下端に設けられた排水トラップとを備えている。排水トラップは、便鉢部から尿が流入する流入口、この流入口から流入した尿が貯留され、水封を形成する水封部を有する内部流路、及び水封部から溢流した尿が流出する流出口を有している。この排水トラップは尿よりも比重が小さいシール液を水封部に注入している。ここで、「比重が小さい」とは、比重がある物質の密度（単位体積当たりの質量）と基準となる標準物質との密度との比であることから、「密度が低い」ことを言う（以下、同じ。）。つまり、排水トラップは尿よりも密度が低いシール液を水封部に注入している。これによって、水封部の上流側で尿の上面を覆うようにシール液が滞留するシール層が形成される。 Patent Document 1 discloses a conventional urinal. This urinal includes a urinal body having a stool portion and a drain trap provided at the lower end of the stool portion. The drain trap has an inflow port for urine flowing from the toilet bowl, urine flowing from the inflow port is stored therein, an internal channel having a water seal part that forms a water seal, and urine overflowing from the water seal part It has an outlet that flows out. This drain trap injects a seal liquid having a specific gravity smaller than that of urine into the water seal portion. Here, “the specific gravity is small” means “the density is low” because it is the ratio of the density of the substance with specific gravity (mass per unit volume) to the density of the reference standard substance ( same as below.). That is, the drain trap injects a sealing liquid having a lower density than urine into the water seal portion. As a result, a seal layer in which the seal liquid stays is formed so as to cover the upper surface of urine on the upstream side of the water seal portion.
　この小便器は、排水トラップに尿を貯留して形成した水封によって、排水トラップより下流側から臭気や虫等が便鉢部側へ侵入することを防止することができる。また、排水トラップに貯留した尿から発生する臭気はシール層によって便鉢部側へ拡散することを防止することができる。このように、この小便器は、洗浄水を利用せずに便鉢部側へ臭気や虫等が侵入することを防止することができるため、大きな節水効果を得ることができる。 This urinal can prevent odors, insects and the like from entering the toilet bowl side from the downstream side of the drain trap by a water seal formed by storing urine in the drain trap. Moreover, the odor generated from the urine stored in the drain trap can be prevented from diffusing to the toilet bowl side by the seal layer. As described above, this urinal can prevent odors, insects, and the like from entering the toilet bowl side without using the washing water, and thus can provide a great water-saving effect.
　また、便鉢部から尿が流入する流入口、この流入口から流入した尿が貯留され、水封を形成する水封部を有する内部流路、水封部から溢流した尿が流出する流出口、及び水封部に貯留した尿が及ぼす浮力によって浮上し、下方から流入口の周縁に当接して流入口を閉鎖するフロート部材を有した排水トラップが知られている。つまり、この排水トラップを便鉢部の下端に設けた小便器も知られている。 Also, an inflow port from which the urine flows from the toilet bowl, the urine flowing from the inflow port is stored, an internal flow path having a water seal forming a water seal, and a flow from which the urine overflowing from the water seal flows out There is known a drain trap having a float member that floats by buoyancy exerted by urine stored in an outlet and a water seal, and closes the inlet by contacting the periphery of the inlet from below. That is, a urinal with this drain trap provided at the lower end of the toilet bowl is also known.
　この小便器も、排水トラップに尿を貯留して形成した水封によって、排水トラップより下流側から臭気や虫等が便鉢部側へ侵入することを防止することができる。また、排水トラップに貯留した尿から発生する臭気はフロート部材が流入口を閉鎖しているため便鉢部側へ拡散することを防止することができる。このように、この小便器も、洗浄水を利用せずに便鉢部側へ臭気や虫等が侵入することを防止することができるため、大きな節水効果を得ることができる。 This urinal can also prevent odors, insects and the like from entering the toilet bowl side from the downstream side of the drain trap by the water seal formed by storing urine in the drain trap. Further, the odor generated from the urine stored in the drain trap can be prevented from diffusing to the toilet bowl side because the float member closes the inflow port. As described above, this urinal can also prevent odors, insects, and the like from entering the toilet bowl without using the washing water, so that a great water saving effect can be obtained.

　しかし、上記した従来の小便器では、便鉢部の表面に付着した尿を能動的に流入口から排水トラップ内へ流入させる機能を有していない。このため、便鉢部の表面に尿が残留する。便鉢部の表面に残留した尿は、時間の経過とともに、臭気が発生したり、便鉢部の表面に尿石を形成したりするおそれがある。つまり、尿は、***された直後には臭気が発生せず、時間の経過と共にバクテリアの作用によって尿中の成分が分解してアンモニアを生成し、臭気を発生する。また、アンモニアの生成によって、ｐＨが上昇すると尿中のカルシウムイオン等が炭酸塩、リン酸塩として析出し、尿石を形成する。尿石が形成されると、尿石が多孔質のため、様々なバクテリアや有機物の温床となり、さらに強烈な臭気を放出することになる。 However, the conventional urinal described above does not have a function of actively flowing urine adhering to the surface of the toilet bowl part from the inlet to the drain trap. For this reason, urine remains on the surface of the toilet bowl. The urine remaining on the surface of the stool may cause odor or may form urine stones on the surface of the stool as time passes. That is, urine does not generate an odor immediately after excretion, but the components in the urine are decomposed by the action of bacteria over time to produce ammonia, generating an odor. Further, when the pH rises due to the generation of ammonia, calcium ions and the like in urine are precipitated as carbonates and phosphates to form uroliths. When urinary stones are formed, the urinary stones are porous and become a hotbed of various bacteria and organic matter, releasing a more intense odor.
　また、排水トラップの水封部の容量よりも多い水量の洗浄水を便鉢部の表面に吐水する一般的な水洗式小便器が存在する。これは、使用者が排尿した後に尿が滞留する水封部内を新たな洗浄水に置換するものである。このため、この水洗式小便器は、便鉢部の表面に尿が残留することが無いが、１回の便器洗浄に２～３Ｌの洗浄水を消費してしまう。 Also, there is a general flush toilet that discharges flush water on the surface of the toilet bowl more than the capacity of the water trap of the drain trap. This replaces the inside of the water seal portion where urine stays after the user urinates with new washing water. For this reason, in this flush toilet bowl, urine does not remain on the surface of the toilet bowl, but 2 to 3 L of wash water is consumed for one toilet flush.
　本発明は、上記従来の実情に鑑みてなされたものであって、臭気及び尿石の発生を少量の洗浄水によって防止することができる小便器を提供することを解決すべき課題としている。 The present invention has been made in view of the above-described conventional situation, and an object to be solved is to provide a urinal capable of preventing the generation of odor and urine stone with a small amount of washing water.
　第１発明の小便器は、便鉢部を有する小便器本体と、
　前記便鉢部から尿及び洗浄水が流入する流入口、この流入口から流入した尿及び洗浄水を混合した混合液体が貯留され、水封を形成する水封部を有する内部流路、及び前記水封部から溢流した前記混合液体が流出する流出口を有し、前記混合液体よりも比重が小さいシール液を前記水封部に注入して前記混合液体の上流側で上面を覆うように滞留させ、前記混合液体から発生する臭気が便鉢部側へ拡散することを防止するシール層を形成しており、前記便鉢部の下端に設けられた排水トラップと、
　前記水封部の容量よりも少ない水量の洗浄水を前記便鉢部の表面に吐水し、前記便鉢部の表面に付着した尿を前記流入口から前記排水トラップ内へ流入させる吐水装置とを備えていることを特徴とする。 The urinal of the first invention comprises a urinal body having a toilet bowl part,
An inflow port through which urine and washing water flow from the toilet bowl, a mixed liquid obtained by mixing urine and washing water flowing in from the inflow port, an internal flow path having a water sealing portion that forms a water seal, and It has an outlet through which the mixed liquid overflowing from the water seal portion flows out, and a sealing liquid having a specific gravity smaller than that of the mixed liquid is injected into the water seal portion so as to cover the upper surface on the upstream side of the mixed liquid. Forming a seal layer for retaining and preventing the odor generated from the mixed liquid from diffusing toward the toilet bowl, and a drain trap provided at the lower end of the toilet bowl,
A water discharging device that discharges washing water having a volume less than the capacity of the water sealing portion to the surface of the toilet bowl, and causes urine adhering to the surface of the toilet bowl to flow into the drain trap from the inlet. It is characterized by having.
　この小便器は、水封部に尿が滞留して臭気を発生しても、シール層によって臭気が便鉢部側へ拡散することを防止することができる。このため、便鉢部に吐水する洗浄水は、水封部の容量よりも少ない水量で便鉢部の表面に付着した尿を流入口から排水トラップ内へ流入させるだけの水量でよい。このように、この小便器は、便鉢部の表面に付着した尿を流入口から排水トラップ内へ流入させる必要最小限の洗浄水を吐水すれば、便鉢部の表面に尿が残留することを防止することができ、便鉢部の表面で尿の成分がバクテリアの作用によって分解され、アンモニアが生成されることを防止することができる。また、アンモニアが生成されないため、便鉢部の表面のｐＨの上昇も防止することができる。 This urinal can prevent the odor from diffusing to the toilet bowl portion side by the sealing layer even if urine stays in the water seal portion to generate odor. For this reason, the washing water discharged into the stool portion may be an amount of water that allows the urine attached to the surface of the stool portion to flow into the drain trap from the inflow port with a smaller amount of water than the capacity of the water seal portion. In this way, this urinal will leave urine on the surface of the toilet bowl if the minimum amount of washing water that allows the urine adhering to the surface of the toilet bowl to flow into the drain trap from the inflow port is discharged. It is possible to prevent urine components from being decomposed by the action of bacteria on the surface of the stool portion and producing ammonia. Moreover, since ammonia is not produced | generated, the raise of the pH of the surface of a toilet bowl part can also be prevented.
　したがって、第１発明の小便器は臭い及び尿石の発生を少量の洗浄水によって防止することができる。 Therefore, the urinal of the first invention can prevent the generation of odor and urine stone with a small amount of washing water.
　第２発明の小便器は、便鉢部を有する小便器本体と、
　前記便鉢部から尿及び洗浄水が流入する流入口、この流入口から流入した尿及び洗浄水を混合した混合液体が貯留され、水封を形成する水封部を有する内部流路、前記水封部から溢流した前記混合液体が流出する流出口、及び貯留した前記混合液体が及ぼす浮力によって浮上し、下方から前記流入口の周縁に当接して前記流入口を閉鎖するフロート部材を有しており、前記便鉢部の下端部に設けられた排水トラップと、
　前記水封部の容量よりも少ない水量の洗浄水を前記便鉢部の表面に吐水し、前記便鉢部の表面に付着した尿を前記流入口から前記排水トラップ内へ流入させる吐水装置とを備えていることを特徴とする。 The urinal of the second invention is a urinal body having a toilet bowl,
An inflow port through which urine and wash water flow from the toilet bowl, an internal flow path having a water seal portion that stores a mixed liquid obtained by mixing urine and wash water flowing in from the inflow port, and forms a water seal; An outlet through which the mixed liquid overflowed from the sealing portion flows out, and a float member that floats by buoyancy exerted by the stored mixed liquid and that contacts the periphery of the inlet from below to close the inlet A drain trap provided at the lower end of the toilet bowl,
A water discharging device that discharges washing water having a volume less than the capacity of the water sealing portion to the surface of the toilet bowl, and causes urine adhering to the surface of the toilet bowl to flow into the drain trap from the inlet. It is characterized by having.
　この小便器は、水封部に尿が滞留して臭気を発生しても、フロート部材が流入口を閉鎖しているため、臭気が便鉢部側へ拡散することを防止することができる。このため、便鉢部に吐水する洗浄水は、水封部の容量よりも少ない水量で便鉢部の表面に付着した尿を流入口から排水トラップ内へ流入させるだけの水量でよい。このように、この小便器は、便鉢部の表面に付着した尿を流入口から排水トラップ内へ流入させる必要最小限の洗浄水を吐水すれば、便鉢部の表面に尿が残留することを防止することができ、便鉢部の表面で尿の成分がバクテリアの作用によって分解され、アンモニアが生成されることを防止することができる。また、アンモニアが生成されないため、便鉢部の表面のｐＨの上昇も防止することができる。 This urinal can prevent the odor from diffusing to the toilet bowl side because the float member closes the inflow port even if urine stays in the water seal and generates odor. For this reason, the washing water discharged into the stool portion may be an amount of water that allows the urine attached to the surface of the stool portion to flow into the drain trap from the inflow port with a smaller amount of water than the capacity of the water seal portion. In this way, this urinal will leave urine on the surface of the toilet bowl if the minimum amount of washing water that allows the urine adhering to the surface of the toilet bowl to flow into the drain trap from the inflow port is discharged. It is possible to prevent urine components from being decomposed by the action of bacteria on the surface of the stool portion and producing ammonia. Moreover, since ammonia is not produced | generated, the raise of the pH of the surface of a toilet bowl part can also be prevented.
　また、この小便器は、吐水装置が洗浄水を便鉢部の表面に吐水し、便鉢部の表面に付着した尿を流入口から排水トラップ内へ流入させる際に、フロート部材によって閉鎖した流入口の上方周辺に残留した尿も一緒に排水トラップ内へ流入する。このため、フロート部材によって閉鎖した流入口の上方周辺に尿が残留しない。 In addition, this urinal is a flow that is closed by a float member when the water discharge device discharges wash water onto the surface of the toilet bowl and allows urine adhering to the surface of the toilet bowl to flow into the drain trap from the inflow port. The urine remaining in the upper periphery of the inlet also flows into the drain trap. For this reason, urine does not remain in the upper periphery of the inlet closed by the float member.
　したがって、第２発明の小便器は臭い及び尿石の発生を少量の洗浄水によって防止することができる。 Therefore, the urinal of the second invention can prevent the generation of odor and urine stone with a small amount of washing water.

　第１発明及び第２発明における好ましい実施の形態を説明する。 Preferred embodiments of the first invention and the second invention will be described.
　第１発明及び第２発明の小便器において、前記吐水装置は、前記便鉢部の所定の表面である第１表面に向けて噴霧状の洗浄水を吐水する噴霧ノズルと、前記第１表面以外の前記便鉢部の表面である第２表面に向けて整流状の洗浄水を吐水する整流ノズルとを有し得る。この場合、噴霧ノズルから洗浄水を噴霧状に吐水するため、少ない洗浄水で便鉢部の広い範囲に洗浄水を噴霧することができ、表面に付着した尿を流入口から排水トラップ内へ流入させることができる。また、噴霧ノズルでは噴霧し難い便鉢部の表面（例えば、噴霧ノズルで洗浄水を噴霧すると便鉢部の外側にはみ出してしまうような便鉢部の表面の左右縁部等の表面）に向けて整流ノズルから整流状の洗浄水を吐水する。このようにすれば、便鉢部の表面全体に洗浄水を良好に流すことができ、便鉢部の表面に付着した尿を確実に流入口から排水トラップ内へ流入させることができる。 In the urinal of the first invention and the second invention, the water discharge device includes a spray nozzle for discharging spray-like washing water toward a first surface which is a predetermined surface of the toilet bowl, and other than the first surface And a rectifying nozzle for discharging rectified washing water toward the second surface, which is the surface of the toilet bowl portion. In this case, since the washing water is sprayed out from the spray nozzle, the washing water can be sprayed over a wide area of the toilet bowl with a little washing water, and the urine adhering to the surface flows into the drain trap from the inlet. Can be made. Also, it is directed to the surface of the toilet bowl that is difficult to spray with the spray nozzle (for example, the left and right edges of the surface of the toilet bowl that protrudes outside the toilet bowl when sprayed with washing water) The rectified cleaning water is discharged from the rectifying nozzle. If it does in this way, wash water can be flowed satisfactorily on the whole surface of a stool part, and urine adhering to the surface of a stool part can be made to surely flow into a drain trap from an inflow port.
　第１発明及び第２発明の小便器において、前記吐水装置は、洗浄水を吐水しない第１モード、一定時間ごとに洗浄水を吐水する第２モード、及び使用される毎に洗浄水を吐水する第３モードを有し、少なくともこれら各モードの内、２つのモードを選択して洗浄水を吐水し得る。この場合、小便器の使用頻度や、温度等の環境等によって変化する臭気の発生具合に応じて吐水装置から洗浄水を吐水する頻度を変更し、臭気の発生を効率的に抑制し、節水を図ることができる。 In the urinal of the first invention and the second invention, the water discharging device discharges the cleaning water every time it is used, and the first mode in which the cleaning water is not discharged, the second mode in which the cleaning water is discharged every predetermined time. There is a third mode, and at least two of these modes can be selected to discharge the wash water. In this case, the frequency of flushing the wash water from the water spouting device is changed according to the frequency of use of the urinal and the odor that changes depending on the environment such as temperature, etc. You can plan.
　次に、第１発明の小便器を具体化した実施例１、及び第２発明の小便器を具体化した実施例２について、図面を参照しつつ説明する。 Next, a first embodiment that embodies the urinal of the first invention and a second embodiment that embodies the urinal of the second invention will be described with reference to the drawings.
＜実施例１＞
　実施例１の小便器は、図１及び図２に示すように、小便器本体１０と、排水トラップ３０と、吐水装置５０とを備えている。小便器本体１０は、便鉢部１１を有しており、壁部Ｗに図示しない吊下げ金具に係止されて固定されている。小便器本体１０は、便鉢部１１の下端が開口した開口部１２を有している。開口部１２は排水連結管１３に連結されている。排水連結管１３は、開口部１２に連続して着脱自在なカートリッジ形態の排水トラップ３０を収納する収納部１４と、収納部１４から壁部Ｗ方向に延びて壁部Ｗから引き出された排水管Ｄに連結する連結部１５とを有している。 <Example 1>
The urinal of Example 1 is provided with the urinal main body 10, the drain trap 30, and the water discharging apparatus 50, as shown in FIG.1 and FIG.2. The urinal body 10 has a toilet bowl 11 and is fixed to the wall W by being locked by a hanging metal fitting (not shown). The urinal body 10 has an opening 12 in which the lower end of the toilet bowl 11 is opened. The opening 12 is connected to a drainage connection pipe 13. The drainage connection pipe 13 includes a storage part 14 that houses a cartridge-type drain trap 30 that is detachable continuously from the opening 12, and a drainage pipe that extends from the storage part 14 in the wall W direction and is drawn out from the wall part W. And a connecting portion 15 connected to D.
　排水トラップ３０は、カートリッジ形態であり、小便器本体１０の開口部１２から排水連結管１３の収納部１４に着脱自在に収納されている。このため、排水トラップ３０は、小便器が使用されることによって後述するシール層Ｓを形成するシール液が減少したり、尿石が排水トラップ３０内に堆積しすぎたりした場合に、容易に交換することができる。排水トラップ３０は、流入口３１、内部流路３２、及び流出口３３を有している。流入口３１は便鉢部１１の下部表面に連続した排水トラップ３０の上面部３４に開口している。内部流路３２は、上面部３４から垂下した隔壁３５によって仕切られ、隔壁３５の下端より下方で連通した第１室３６Ａと第２室３６Ｂとを有している。第１室３６Ａと第２室３６Ｂとで水封部３６を構成している。第１室３６Ａは、流入口３１に連通しており、流入口３１から尿及び洗浄水が流入する。第１室３６Ａと第２室３６Ｂに尿及び洗浄水を混合した混合液体が貯留される。排水トラップ３０は、第２室３６Ｂの下流側に連通し、第２室３６Ｂから溢流した混合液体が流下する流出路３７を有している。流出口３３は、流出路３７の下流端に形成され、排水トラップ３０の下面部３８の縁部に開口している。 The drain trap 30 is in the form of a cartridge and is detachably accommodated in the accommodating portion 14 of the drain connecting pipe 13 from the opening 12 of the urinal body 10. For this reason, the drain trap 30 is easily replaced when the urinal is used and the seal liquid forming the seal layer S to be described later decreases, or when urine stone accumulates too much in the drain trap 30. can do. The drain trap 30 has an inflow port 31, an internal flow path 32, and an outflow port 33. The inflow port 31 opens to the upper surface portion 34 of the drain trap 30 that is continuous with the lower surface of the toilet bowl 11. The internal flow path 32 is partitioned by a partition wall 35 that hangs down from the upper surface portion 34, and has a first chamber 36 </ b> A and a second chamber 36 </ b> B that communicate with each other below the lower end of the partition wall 35. The first chamber 36A and the second chamber 36B constitute a water seal portion 36. The first chamber 36 </ b> A communicates with the inflow port 31, and urine and washing water flow from the inflow port 31. A mixed liquid obtained by mixing urine and washing water is stored in the first chamber 36A and the second chamber 36B. The drain trap 30 communicates with the downstream side of the second chamber 36B and has an outflow path 37 through which the mixed liquid overflowing from the second chamber 36B flows down. The outflow port 33 is formed at the downstream end of the outflow passage 37 and opens at the edge of the lower surface portion 38 of the drain trap 30.
　排水トラップ３０は、非溶水性であり、混合液体よりも比重が小さいシール液を第１室３６Ａに注入して、貯留された混合液体の上流側で上面を覆うようにシール液を滞留させてシール層Ｓを形成している。シール層Ｓは混合液体から発生する臭気が便鉢部１１側へ拡散することを防止することができる。 The drain trap 30 is insoluble in water and injects a sealing liquid having a specific gravity smaller than that of the mixed liquid into the first chamber 36A, and the sealing liquid is retained so as to cover the upper surface on the upstream side of the stored mixed liquid. A seal layer S is formed. The sealing layer S can prevent the odor generated from the mixed liquid from diffusing to the toilet bowl 11 side.
　吐水装置５０は、便鉢部１１の左右中央の表面である第１表面に向けて噴霧状の洗浄水を吐水する１個の噴霧ノズル５１と、（第１表面以外の便鉢部１１の表面である）第１表面の左右の第２表面、つまり便鉢部１１の表面の左右縁部に向けて整流状の洗浄水を吐水する２個の整流ノズル５２とを有している。 The water discharge device 50 includes one spray nozzle 51 that discharges spray-like washing water toward a first surface that is a central surface on the left and right sides of the toilet bowl 11, and a surface of the toilet bowl 11 other than the first surface. And two rectifying nozzles 52 for discharging rectified washing water toward the left and right second surfaces of the first surface, that is, the left and right edges of the surface of the toilet bowl 11.
　吐水装置５０は、給水源に連通した主給水路５３と、主給水路５３に設けた開閉弁５４と、主給水路５３の下流端に設けた三方弁５５と、三方弁５５を介して主給水路５３に連通した第１分岐水路５６Ａ及び第２分岐水路５６Ｂとを有している。開閉弁５４と三方弁５５は、図示しない制御装置によって開閉制御されている。第１分岐水路５６Ａの下流端に噴霧ノズル５１が連結している。第２分岐水路５６Ｂは２つに分岐されており、夫々の下流端に整流ノズル５２が連結している。 The water discharge device 50 is connected to the main water supply channel 53 via the main water supply channel 53, the open / close valve 54 provided in the main water supply channel 53, the three-way valve 55 provided at the downstream end of the main water supply channel 53, and the three-way valve 55. The first branch water channel 56 </ b> A and the second branch water channel 56 </ b> B communicated with the water supply channel 53. The on-off valve 54 and the three-way valve 55 are controlled to open and close by a control device (not shown). The spray nozzle 51 is connected to the downstream end of the first branch water channel 56A. The second branch water channel 56B is branched into two, and a rectifying nozzle 52 is connected to each downstream end.
　このように形成された小便器は、使用者が小便器の前に近づいたことを図示しない人体検知センサーが検知すると、噴霧ノズル５１から洗浄水を吐水するように三方弁５５を切り替えて、開閉弁５４を設定時間の間、開弁し、前洗浄を実行する。前洗浄時において、噴霧状に洗浄水を吐水するため、少ない洗浄水で便鉢部１１の第１表面を濡らすことができ、使用者が排尿した際に便鉢部１１の第１表面に尿が付着し難くなる。 When the human body detection sensor (not shown) detects that the user has approached the front of the urinal, the urinal formed in this way switches the three-way valve 55 to discharge the washing water from the spray nozzle 51, and opens and closes the urinal. The valve 54 is opened for a set time, and pre-cleaning is performed. At the time of pre-washing, since the washing water is discharged in a spray form, the first surface of the toilet bowl 11 can be wetted with a small amount of washing water, and urine is placed on the first surface of the toilet bowl 11 when the user urinates. Becomes difficult to adhere.
　そして、使用者が排尿した後に小便器の前から立ち去ったことを人体検知センサーが検知すると、噴霧ノズル５１と整流ノズル５２とから洗浄水を吐水するように三方弁５５を切り替えて、開閉弁５４を設定時間の間、開弁し、本洗浄を実行する。本洗浄で噴霧ノズル５１と整流ノズル５２とから吐水する洗浄水は、便鉢部１１の表面に付着した尿を流入口３１から排水トラップ３０内へ流入させるものであり、水量は排水トラップ３０の水封部３６の容量よりも少なく、水勢が弱くてよい。このように、本洗浄の際に排水トラップ３０の流入口３１から第１室３６Ａに流入する洗浄水の水量が少なく、水勢も弱いため、排水トラップ３０内のシール層Ｓが下流側に排出され難い。このため、排水トラップ３０内のシール層Ｓが長期間、良好に存在し、臭気が便鉢部１１側へ拡散することを防止することができる。 When the human body detection sensor detects that the user has left the urinal after urinating, the three-way valve 55 is switched to discharge the washing water from the spray nozzle 51 and the rectifying nozzle 52, and the on-off valve 54 is switched. Is opened for the set time and the main cleaning is executed. The washing water discharged from the spray nozzle 51 and the rectifying nozzle 52 in the main washing causes the urine adhering to the surface of the toilet bowl 11 to flow into the drain trap 30 from the inflow port 31. It is less than the capacity of the water seal 36 and the water force may be weak. As described above, since the amount of cleaning water flowing into the first chamber 36A from the inlet 31 of the drain trap 30 during the main cleaning is small and the water flow is weak, the seal layer S in the drain trap 30 is discharged downstream. hard. For this reason, the seal layer S in the drain trap 30 can be satisfactorily present for a long period of time, and odor can be prevented from diffusing to the toilet bowl 11 side.
　この小便器は、水封部３６に尿が滞留して臭気を発生しても、シール層Ｓによって臭気が便鉢部１１側へ拡散することを防止することができる。このため、便鉢部１１に吐水する洗浄水は、水封部３６の容量よりも少ない水量で便鉢部１１の表面に付着した尿を流入口３１から排水トラップ３０内へ流入させるだけの水量でよい。このように、この小便器は、便鉢部１１の表面に付着した尿を流入口３１から排水トラップ３０内へ流入させる必要最小限の洗浄水を吐水すれば、便鉢部１１の表面に尿が残留することを防止することができ、便鉢部１１の表面で尿の成分がバクテリアの作用によって分解され、アンモニアが生成されることを防止することができる。また、アンモニアが生成されないため、便鉢部１１の表面のｐＨの上昇も防止することができる。 This urinal can prevent the odor from diffusing to the toilet bowl 11 side by the sealing layer S even if urine stays in the water seal portion 36 to generate odor. For this reason, the washing water discharged to the toilet bowl 11 is an amount of water that allows the urine adhering to the surface of the toilet bowl 11 to flow into the drain trap 30 from the inlet 31 with a smaller amount of water than the capacity of the water seal 36. It's okay. As described above, when the urinal adhered to the surface of the toilet bowl 11 is discharged from the inflow port 31 into the drain trap 30, the urinal discharges urine on the surface of the toilet bowl 11. Can be prevented, and urine components can be prevented from being decomposed by the action of bacteria on the surface of the stool portion 11 to generate ammonia. Moreover, since ammonia is not produced | generated, the raise of the pH of the surface of the toilet bowl part 11 can also be prevented.
　したがって、実施例１の小便器は臭い及び尿石の発生を少量の洗浄水によって防止することができる。 Therefore, the urinal of Example 1 can prevent the generation of odor and urine stone with a small amount of washing water.
　また、この小便器は、噴霧ノズル５１から洗浄水を噴霧状に吐水するため、少ない洗浄水で便鉢部１１の広い範囲（第１表面）に洗浄水を噴霧することができ、便鉢部１１の表面に付着した尿を流入口３１から排水トラップ３０内へ流入させることができる。また、噴霧ノズル５１では噴霧し難い便鉢部１１の表面の左右縁部（第２表面）に向けて整流ノズル５２から整流状の洗浄水を吐水する。このため、便鉢部１１の表面全体に洗浄水を良好に流すことができ、便鉢部１１の表面に付着した尿を確実に流入口３１から排水トラップ３０内へ流入させることができる。 Moreover, since this urinal discharges the washing water from the spray nozzle 51 in the form of a spray, the washing water can be sprayed on a wide range (first surface) of the toilet bowl 11 with a little washing water. 11 can flow into the drain trap 30 from the inlet 31. Further, rectified washing water is discharged from the rectifying nozzle 52 toward the left and right edge portions (second surface) of the surface of the toilet bowl 11 that is difficult to spray with the spray nozzle 51. For this reason, washing water can be satisfactorily flowed over the entire surface of the toilet bowl 11, and urine adhering to the surface of the toilet bowl 11 can be reliably introduced into the drain trap 30 from the inlet 31.
　また、吐水装置５０は、前洗浄及び本洗浄をしない（洗浄水を吐水しない）第１モード、一定時間ごと（例えば、３０分ごと）に本洗浄を行う（洗浄水を吐水する）第２モード、及び小便器が使用される毎に前洗浄及び本洗浄を行う（洗浄水を吐水する）第３モードを有している。そして、吐水装置５０は、図５（Ａ）に示すように、１年の内、３月から９月までを第３モードで駆動し、１０月から２月までを第１モードで駆動するようにすることができる。つまり、３月から９月までは、比較的、気温が高いため、便鉢部１１の表面に付着した尿の乾燥が早くなる等、臭気が発生し易くなることから、第３モードで駆動し、１０月から２月までは、比較的、気温が低いため、便鉢部１１の表面に付着した尿の乾燥が遅い等、臭気が発生し難くなることから第１モードで駆動する。 Moreover, the water discharging apparatus 50 is the 1st mode which does not perform pre-cleaning and main cleaning (does not discharge cleaning water), and the 2nd mode which performs main cleaning (for example, every 30 minutes) at regular intervals (discharges cleaning water). , And every time the urinal is used, it has a third mode in which pre-cleaning and main cleaning are performed (washing water is discharged). Then, as shown in FIG. 5A, the water discharge device 50 is driven in the third mode from March to September in the year, and is driven in the first mode from October to February. Can be. In other words, from March to September, since the temperature is relatively high, the urine adhering to the surface of the toilet bowl 11 is likely to be dried quickly and the odor is likely to be generated. From October to February, since the temperature is relatively low, the urine adhering to the surface of the toilet bowl 11 is slow to dry and the odor is unlikely to be generated.
　また、吐水装置５０は、図５（Ｂ）に示すように、１日の内、朝の６：００から夜中の０：００までを第３モードで駆動し、夜中の０：００から朝の６：００までを第２モードで駆動することができる。つまり、朝の６：００から夜中の０：００までは、小便器を利用する頻度が多いため、便鉢部１１の表面に尿が付着する機会が多い等、臭気が発生し易くなることから、第３モードで駆動し、夜中の０：００から朝の６：００までは、小便器を利用する頻度が少ないため、便鉢部１１の表面に尿が付着する機会が少ない等、臭気が派生し難くなることから第２モードで駆動する。 In addition, as shown in FIG. 5B, the water discharge device 50 drives in the third mode from 6:00 in the morning to midnight in the day, and starts at midnight in the morning. Up to 6:00 can be driven in the second mode. That is, from 6:00 in the morning to midnight in the morning, since the frequency of using the urinal is high, it is easy to generate odor, such as urine often attaching to the surface of the toilet bowl 11. Driven in the third mode, from midnight in the morning to 6:00 in the morning, since the frequency of using the urinal is low, there is less chance of urine adhering to the surface of the toilet bowl 11, etc. Since it is difficult to derive, it is driven in the second mode.
＜実施例２＞
　実施例２の小便器は、図３及び図４に示すように、排水トラップ１３０の形態が実施例１と相違する。他の構成は、実施例１と同様であり、同一の構成は同一の符号を付し、詳細な説明を省略する。 <Example 2>
The urinal of Example 2 is different from Example 1 in the form of a drain trap 130 as shown in FIGS. 3 and 4. Other configurations are the same as those of the first embodiment, and the same configurations are denoted by the same reference numerals, and detailed description thereof is omitted.
　排水トラップ１３０も、カートリッジ形態であり、小便器本体１０の開口部１２から排水連結管１３の収納部１４に着脱自在に収納されている。このため、排水トラップ１３０は、後述するフロート部材１３４が損傷したり、尿石が排水トラップ１３０内に堆積しすぎたりした場合に、容易に交換することができる。排水トラップ１３０は、流入口１３１、内部流路１３２、流出口１３３、及びフロート部材１３４を有している。流入口１３１は排水トラップ１３０の上面部１３５の中央に開口している。排水トラップ１３０の上面部１３５は流入口１３１の周縁部が流入口１３１に向けて下方に傾斜した傾斜面で形成されている。内部流路１３２は、流入口１３１の周りに上面部１３５から垂下した円筒状の隔壁１３６によって仕切られ、隔壁１３６の下端より下方で連通した第１室１３７Ａと第２室１３７Ｂとを有している。第１室１３７Ａと第２室１３７Ｂとで水封部１３７を構成している。第１室１３７Ａは、流入口１３１に連通しており、流入口１３１から尿及び洗浄水が流入する。第１室１３７Ａと第２室１３７Ｂに尿及び洗浄水を混合した混合液体が貯留される。排水トラップ１３０は、第２室１３７Ｂの下流側に連通し、第２室１３７Ｂから溢流した混合液体が流下する流出路１３８を有している。流出口１３３は、流出路１３８の下流端に形成され、排水トラップ１３０の下面部１３９の縁部に開口している。 The drain trap 130 is also in the form of a cartridge and is detachably accommodated in the accommodating portion 14 of the drain connecting pipe 13 from the opening 12 of the urinal body 10. For this reason, the drain trap 130 can be easily replaced when a float member 134 (to be described later) is damaged, or when urine stone accumulates too much in the drain trap 130. The drain trap 130 has an inlet 131, an internal channel 132, an outlet 133, and a float member 134. The inflow port 131 opens at the center of the upper surface portion 135 of the drain trap 130. The upper surface portion 135 of the drain trap 130 is formed with an inclined surface in which the peripheral edge portion of the inlet 131 is inclined downward toward the inlet 131. The internal channel 132 has a first chamber 137A and a second chamber 137B that are partitioned by a cylindrical partition wall 136 that hangs from the upper surface portion 135 around the inflow port 131 and communicates below the lower end of the partition wall 136. Yes. The first chamber 137A and the second chamber 137B constitute a water seal 137. The first chamber 137 </ b> A communicates with the inlet 131, and urine and washing water flow from the inlet 131. A mixed liquid obtained by mixing urine and washing water is stored in the first chamber 137A and the second chamber 137B. The drain trap 130 communicates with the downstream side of the second chamber 137B and has an outflow path 138 through which the mixed liquid overflowing from the second chamber 137B flows down. The outflow port 133 is formed at the downstream end of the outflow passage 138 and opens at the edge of the lower surface portion 139 of the drain trap 130.
　フロート部材１３４は、第１室１３７Ａ内に収納されており、円柱状の胴部１３７Ａと球面状の上端部１３４Ｂとを有している。フロート部材１３４は、水封部１３７に貯留した混合液体が及ぼす浮力によって浮上し、球面状の上端部１３７Ｂが流入口１３１の周縁に当接して流入口１３１を閉鎖している。このため、封水部１３７に貯留した混合液体から発生する臭気が便鉢部１１側へ拡散することを防止することができる。 The float member 134 is housed in the first chamber 137A and has a cylindrical body 137A and a spherical upper end 134B. The float member 134 floats due to the buoyancy exerted by the liquid mixture stored in the water seal portion 137, and the spherical upper end portion 137 </ b> B contacts the peripheral edge of the inflow port 131 to close the inflow port 131. For this reason, it is possible to prevent the odor generated from the mixed liquid stored in the sealing part 137 from diffusing to the toilet bowl 11 side.
　このように形成された小便器は、使用者が小便器の前に近づいたことを図示しない人体検知センサーが検知すると、噴霧ノズル５１から洗浄水を吐水するように三方弁５５を切り替えて、開閉弁５４を設定時間の間、開弁し、前洗浄を実行する。前洗浄時において、噴霧状に洗浄水を吐水するため、少ない洗浄水で便鉢部１１の第１表面を濡らすことができ、使用者が排尿した際に便鉢部１１の第１表面に尿が付着し難くなる。 When the human body detection sensor (not shown) detects that the user has approached the front of the urinal, the urinal formed in this way switches the three-way valve 55 to discharge the washing water from the spray nozzle 51, and opens and closes the urinal. The valve 54 is opened for a set time, and pre-cleaning is performed. At the time of pre-washing, since the washing water is discharged in a spray form, the first surface of the toilet bowl 11 can be wetted with a small amount of washing water, and urine is placed on the first surface of the toilet bowl 11 when the user urinates. Becomes difficult to adhere.
　そして、使用者が排尿した後に小便器の前から立ち去ったことを人体検知センサーが検知すると、噴霧ノズル５１と整流ノズル５２とから洗浄水を吐水するように三方弁５５を切り替えて、開閉弁５４を設定時間の間、開弁し、本洗浄を実行する。本洗浄で噴霧ノズル５１と整流ノズル５２とから吐水する洗浄水は、便鉢部１１の表面に付着した尿を流入口１３１から排水トラップ１３０内へ流入させるものであり、水量は排水トラップ１３０の水封部１３７の容量よりも少なく、水勢が弱くてよい。 When the human body detection sensor detects that the user has left the urinal after urinating, the three-way valve 55 is switched to discharge the washing water from the spray nozzle 51 and the rectifying nozzle 52, and the on-off valve 54 is switched. Is opened for the set time and the main cleaning is executed. The washing water discharged from the spray nozzle 51 and the rectifying nozzle 52 in the main washing causes the urine adhering to the surface of the toilet bowl 11 to flow into the drain trap 130 from the inflow port 131. It is less than the capacity of the water seal part 137 and the water force may be weak.
　この小便器は、水封部１３７に尿が滞留して臭気を発生しても、フロート部材１３４が流入口１３１を閉鎖しているため、臭気が便鉢部１１側へ拡散することを防止することができる。このため、便鉢部１１に吐水する洗浄水は、水封部１３７の容量よりも少ない水量で便鉢部１１の表面に付着した尿を流入口１３１から排水トラップ１３０内へ流入させるだけの水量でよい。このように、この小便器は、便鉢部１１の表面に付着した尿を流入口１３１から排水トラップ１３０内へ流入させる必要最小限の洗浄水を吐水すれば、便鉢部１１の表面に尿が残留することを防止することができ、便鉢部１１の表面で尿の成分がバクテリアの作用によって分解され、アンモニアが生成されることを防止することができる。また、アンモニアが生成されないため、便鉢部１１の表面のｐＨの上昇も防止することができる。 This urinal prevents the odor from diffusing to the toilet bowl 11 side because the float member 134 closes the inlet 131 even if urine stays in the water seal 137 and generates odor. be able to. For this reason, the washing water discharged to the toilet bowl 11 is an amount of water that allows the urine adhering to the surface of the toilet bowl 11 to flow into the drain trap 130 from the inlet 131 with a smaller amount of water than the capacity of the water seal 137. It's okay. As described above, when the urinal adhered to the surface of the toilet bowl 11 is discharged from the inflow port 131 into the drain trap 130, the urinal discharges urine on the surface of the toilet bowl 11. Can be prevented, and urine components can be prevented from being decomposed by the action of bacteria on the surface of the stool portion 11 to generate ammonia. Moreover, since ammonia is not produced | generated, the raise of the pH of the surface of the toilet bowl part 11 can also be prevented.
　また、この小便器は、吐水装置５０が洗浄水を便鉢部１１の表面に吐水し、便鉢部１１の表面に付着した尿を流入口１３１から排水トラップ１３０内へ流入させる際に、フロート部材１３４によって閉鎖した流入口１３１の上方周辺に残留した尿も一緒に排水トラップ１３０内へ流入する。このため、フロート部材１３４によって閉鎖した流入口１３１の上方周辺に尿が残留しない。 Further, the urinal floats when the water discharging device 50 discharges washing water to the surface of the toilet bowl 11 and causes the urine adhering to the surface of the toilet bowl 11 to flow into the drain trap 130 from the inlet 131. The urine remaining in the upper periphery of the inlet 131 closed by the member 134 also flows into the drain trap 130 together. For this reason, urine does not remain in the upper periphery of the inlet 131 closed by the float member 134.
　したがって、実施例２の小便器も臭い及び尿石の発生を少量の洗浄水によって防止することができる。 Therefore, the urinal of Example 2 can also prevent the generation of odor and urine stone with a small amount of washing water.
　また、この小便器は、噴霧ノズル５１から洗浄水を噴霧状に吐水するため、少ない洗浄水で便鉢部１１の広い範囲（第１表面）に洗浄水を噴霧することができ、便鉢部１１の表面に付着した尿を流入口１３１から排水トラップ１３０内へ流入させることができる。また、噴霧ノズル５１では噴霧し難い便鉢部１１の表面の左右縁部（第２表面）に向けて整流ノズル５２から整流状の洗浄水を吐水する。このため、便鉢部１１の表面全体に洗浄水を良好に流すことができ、便鉢部１１の表面に付着した尿を確実に流入口１３１から排水トラップ１３０内へ流入させることができる。 Moreover, since this urinal discharges washing water from the spray nozzle 51 in the form of a spray, the washing water can be sprayed over a wide range (first surface) of the toilet bowl 11 with a small amount of washing water. 11 can flow into the drainage trap 130 from the inlet 131. Further, rectified washing water is discharged from the rectifying nozzle 52 toward the left and right edge portions (second surface) of the surface of the toilet bowl 11 that is difficult to spray with the spray nozzle 51. For this reason, washing water can be satisfactorily flowed over the entire surface of the toilet bowl 11, and urine adhering to the surface of the toilet bowl 11 can be reliably introduced into the drain trap 130 from the inlet 131.
