Description

201237238 六、發明說明： 【發明所屬之技術領域】 本發明係關於-種便器洗淨裝置及水洗式便器者。 【先前技術】 專利文獻1揭料具備f知之便m裝置之水洗式便 益此水洗式便器具備有便！I本體與便器洗淨裝置。此水洗 式便°σ係使便器洗淨裝置將洗淨水供給至便器本體而執行 便器洗淨。便II本體具有便斗部、及連通於此便斗部下游側 之便器排水路。便器洗淨裝置具有水箱（tank)、中空管、排 氣L路及仏水路。水柏係蓄積供給至便器本體之洗淨水。中 空管係朝垂直方向延伸地收納於水箱内，且下端開口於水箱 内開口。排氣通路係經由較水箱之最高蓄水位高之位置，並 連通中空管之上端部與便器本體之便ϋ排水路。供水路係連 通水箱與便器本體之便斗部。 此水洗式便器若執行便器洗淨，就會將蓄積於水箱之洗淨 水經由供水路而供給至便斗部，因此水箱内之水位會下降。 又，中空f内之水位亦略慢於水箱内之水位下降而下降。因 ‘此，中空管係經由通氣路抽吸便器排水路内之氣體。 • 此水洗式便器若執行便器洗淨，則供給至便斗部之洗淨水 就會流入便器排水路内，並且中空管就會抽吸便器排水路内 之氣體’因此’可以較少之洗淨水於便器排水路内產生虹吸 作用（siphon effect)。因此，此水洗式便器可利用便器排水路 10Π03989 3 201237238 内產生之虹吸作用’將便斗部内之機物等向便器本體外排出。 又，專利文獻2揭示有具備習知之另一便器洗淨裝置之水 洗式便器。此水洗式便器係具備有便器本體與便器洗淨裝 置。此水洗錢H錢便料淨裝置將洗淨水供給至便料 體而執行便器洗淨。便器洗淨裝置具備有水箱、喷射录⑽ pump) m供林。水難、蓄雜給至便n本體之洗淨 水。喷射泵係具有嘴嘴(no刪及配置於與喷嘴隔著間隙相 對向之位置之喉部（th咖）。此喷射㈣以沈沒於水箱内之 洗淨水中之方式配置。容器係包圍喷射m端開放。此 容器係以上端成為低於水箱内洗淨水最高水位之位置之方 式形成。又，此容器具有貫設於側面之開口、及開關此開口 之開關蓋。供水路係連通喷射泵與便器本體。 此水洗式便器若自便器洗淨裝置之喷嘴喷射洗淨水，則該 洗淨水就會吸引容μ之洗淨水流人喉部内。如此，可經由 供水路供給至便n本狀洗淨水，加上&自t冑喷射洗淨水 所吸引之洗淨水，可使流量（每單位時間移動之流體體積， 以下相同）增多。 又，此水洗式便器藉由利用開關蓋開關設置於便器洗淨裝 置之容器側面之開口’可增減供給至便器本體之洗淨水之^ 量。即，於使容器之開口開放之狀態下，容器外之洗淨水可 經由開口流入容器内。因此，容器外之洗淨水亦可藉由嘴射 泵吸引，而可經由供水路供給至便器本體。 101103989 4 201237238 另一方面，於藉由開關蓋將容器之開口封閉之狀態下，若 水相内洗淨水之水位變得與容器之上端相等，則於該時間 點，谷盗外之洗淨水將無法流入容器内。因此，於水箱内洗 淨水之水位變得與容器之上端相等後，可僅使容器内之洗淨 水由噴射泵所吸引，並經由供水路供給至便器本體。 如上所述’與在將貫設於容器側面之開口開放之狀態下將 洗淨水供給至便器本體時相比，在利用開關蓋將開口封閉之 狀態下將洗淨水供給至便器本體時，可供給至便器本體之洗 淨水之水量會變少。因此，此便器洗淨裝置可執行洗淨水量 較多之便器洗淨（大洗淨）與洗淨水量較少之便器洗淨（小洗 淨）。 [先前技術文獻] [專利文獻] 專利文獻1:曰本專利實開平5-57080號公報 專利文獻2 :曰本專利特開2004-156382號公報 【發明内容】 (¾明所欲解決之問題） 、、;'而在專利文獻1之水洗式便器中，中空管内洗淨水之 Jc位係保持在略高於水箱内洗淨水之水位之狀態（水箱内與 中二ί内之水位差較小之狀態）而下降。因此，中空管從開 σ抽及後直至結束為止係以較弱之抽吸力抽吸便 器排水路 内之氣體。由此，此水洗式便器存在有中空管不能良好地柚 101103989 201237238 吸便為排水路内之氣體歧便器排水路内之虹吸作用產生 及持續之虞。即，因為中空管之抽吸力較弱，而存在有於便 器排水路⑽會產生虹吸作欧虞。又，於便輯水路内在 與π及作用後’存在有便器排水路内之負壓力變得比中空 1抽吸力強’使氣體逆流至便n排水路内而使虹吸作用提 早結束之虞。因此，此水洗式便n存在有無法藉由執行便器 洗淨而良好地進行將便斗部内之穢物等排出之虞。 第1發明及第2發明係ϋ於上述f知之實際情況所完成 者其應解決之課題在於提供一種可良好地進行便器洗淨之 便器洗淨裝置及具備有該便器洗淨裝置之水洗式便器。 又於專利文獻1之水洗式便器中，若便斗部或便器排水 路之形狀不同，則存在有即便使對便斗部供給之洗淨水之流 量相同，便器排水路之洗淨水流量亦不相同之情形。便器排 水路内洗淨水之流量會對中空管抽吸便器排水路内氣體之 抽吸力、以及將便斗部内之穢物等排出之排出力造成影響。 因此’在便器排水路内洗淨水之流量較多之便器本體中， 存在有中空管自便器排水路内抽吸氣體之抽吸力過強，而將 在便器排水路内流動之穢物吸入至排氣通路内之虞。若因吸 入至排軋通路内之槺物導致排氣通路堵塞，則存在有於其後 之便器洗淨中無法於便器排水路内良好地產生虹吸作用之 虞。另一方面，在便器排水路内洗淨水之流量較少之便器本 體中，雖不存在將穢物吸入至排氣通路内之虞，但存在有無 101103989 6 201237238 法於便器排水路内良好地產生虹吸作用，而導致將穢物等向 便器本體外排出之排出力下降之虞。如此，此水洗式便器存 在有若便斗部或便器排水路之形狀不同，則無法藉由執行便 器洗淨而良好地進行將便斗部内之穢物等排出之虞。 第3發明係鑒於上述習知之實際情況所完成者，其應解決 之課題在於提供一種可良好地進行便器洗淨之便器洗淨裝 置及具備有該便器洗淨裝置之水洗式便器。 又，於專利文獻2之水洗式便器中，為了使便器洗淨裝置 藉由喷射栗吸引水箱内之洗淨水，就必須使喷躲成為沈沒 於水箱内之洗淨水中之狀態。因此，為了將f積於水箱内之 洗淨水有效地利用於冑器洗淨，就必須將喷射栗配置於水箱 底面之附近。 於將喷射栗配置於水箱底面之附近，且將水箱配置於低於 便益本體上表面之位置之情形時，存在有連通喷射栗與便器 本體之供水路變長，且供水路之上升斜率紐之虞^若供水 路變長、或供水路之上升斜率變陡，則通過供水路之洗淨水 :邀力損失會變大，由於將導致供給至便器本體之洗淨水之 流量下降’因此，存在有便器洗淨變得不充分之虞。 第4發明係馨於上述習知之實際情況所完成者，其應解決 =簡在於提供—種具有設置位置之自由度，且可良^地進 行便器洗淨之便器洗淨裝置及具備有該便器洗淨裝置之水 洗式便器。 101103989 201237238 (解決問題之手段） 第1發明之便器洗淨裝置係將洗淨水供給至具有便斗部 及連通於此便斗部下游側之便器排水路之便器本體者，其 徵在於具備有： “ ’ 第1水箱，其用以蓄積洗淨水； 第2水箱，其下部開口連通於上述第1水箱，且相較於下 方區域而在上方區域内使每單位高度之蓄水量增多； 通氣路，其經由較上述第！水箱之最高蓄水位高之位置且 連通上述第2水箱與上述便器排水路； 供水路，其連通上述第！水箱與上述便斗部；及 延遲裝置，其係於較經由上述供水路開始將蓄積於上 1水箱之洗淨水向上錢斗部供給時紐之時機，使自 便器排水路側流向上述第2水箱側之上述通氣 心 流量成為最大。 乳體 此便器洗淨裝置係經由供水路將蓄積於第丨水箱之 水供給至便斗部，藉此執行便器洗淨。此時，利用第2奸 内水位之下降’使第1水箱經㈣氣路減便轉水= 氣體。藉此，即便是少量之爻 之冼淨水亦可於便器排水路内產生 虹吸作用’而可良好地排出便斗内之穢物等。 又，此便料淨裝置由於藉由料裝置而於較開始進行便 器洗淨時更慢之時機，使自通裔 目通礼路内之便器排水路側流向第 101103989 1 水箱側之氣體流量成為最大，因此可使第2水箱内之水位 201237238 下降延遲。因此 於第2水箱内之&/期助幻水箱内之水位下降會快 之水位差變大。第】下降，而可使第1水箱内與第2水箱内 第2水箱之抽吸水箱内與第2水箱内水位差之大小係與 力之抽吸力，強弱成比例。因此’第2水箱可具有趣 此便器洗衫置心:氣抽錢器排水路内之氣體。因此， 貫地在便器排水路内產生虹吸作用。 / I♦裝置係使第2水箱於上方區域内每單位$ 度之畜水量多於下士广 干丨此叫 、卜方區域。因此，即便於藉由延遲裝置 自便器排水路側# “ k絲置而使 為最大，且㈣Ί 2水箱侧之通氣路内之氣體流量成 ' 2水箱内之洗淨水以大流量流出至第1水箱 =之狀况下’第2水箱内之水位亦緩慢地下降。因此， 益洗淨x置係第1水箱内與第2水箱内之水位差不會急遽地 減少因此’此便器洗淨裝置可維持第2水箱之較強抽吸力。 如此’由於此便器洗淨裝置藉由在便器排水路内所產生之 虹吸作用可長時間維持使第2水箱之抽吸力較強於便器挪 水路内之負壓力之狀態，故可防止於虹吸作用在持續之過種 中，氣體自第2水箱側逆流至便器排水路内。因此，此便器 洗淨裝置可使虹吸作用持續，而可利用虹吸作用將便斗内之 穢物等良好地向便器本體外排出。 因此’第1發明之便器洗淨裝置可良好地進行便器洗淨。 第2發明之便器洗淨裝置係將洗淨水供給至具有便斗 部、及連通於此便斗部下游側之便器排水路之便器本體者， 101103989 9 201237238 其特徵在於具備有： 二=，蓄積洗淨水，且相較於下方區域而在上 方&域内減少每單位高叙f水量； 仕 第2水箱’其下部開口連通於上述第1水箱. 通氣路，其經由較上述第1水箱之最高蓄水位高之位置， 且連通上述第2水箱與上述便器排水路； 延遲I置述第1水箱與上述便斗部；及 1水箱之洗n係於較經由上述供水路開始將f積於上述第 水路向上述便斗部供給之時機，使自上述便器排 第2水箱侧之上述魏路内之氣體流量成 崎瑕大。 此便器洗淨裝置祕由供林料積於第丨水箱之洗淨 水供給至便斗部藉此執行便器洗淨。此時，利用第2水箱内 水位之下降，使第2水箱經由通氣路抽吸便器排水路内之氣 體。藉此’即便是少量之洗淨水亦可於便器排水路内產生虹 及作用’而可良好地排出便斗内之穗物等。 又，此便器洗淨裝置由於藉由延遲裝置而於較開始進行便 器洗淨時更慢之時機，使自通氣路内之便器排水路側流向第 2水箱側之氣體流量成為最大，因此可使第2水箱内之水位 下降延遲。因此，於該期間内，第丨水箱内之水位下降會快 於第2水箱内之水位下降，而可使第丨水箱内與第2水箱内 之水位差變大。尤其，此便器洗淨裴置由於使第丨水箱於上 '01103989 10 201237238 方區域内每單位高度之蓄水量少於下方區域，因此若開弘、 行便器洗淨就可使第1水箱内之水位急遽下降。因此， 水箱内與第2水箱内之水位差會變大，而可使第2水箱具有 強力之抽吸力，因此，可一口氣抽吸便器排水路内之氣體 * 因此，此便器洗淨裝置可確實地使便器排水路内產生虹 久1乍 • 用。 又’此便器洗淨裝置係使第2水箱抽吸便器排水路内之广 體，並且使洗淨水向第1水箱内流出，但由於第1水箱之下 方區域每单位局度之畜水I多於上方區域，因此可減少因為 該洗淨水所造成第1水相内之水位上升。因此，可抑制第1 水箱内與第2水箱内水位差之減少’而可抑制第2水箱之抽 吸力減少。因此，此便器洗淨裝置可維持第2水箱之強抽吸 力。 如此，由於此便器洗淨裝置可長時間維持在第2水箱之抽 吸力車乂由便器排水路内產生之虹吸作用所導致之便器排水 路内之負壓力強之狀態，故可防止於虹吸作用在持續之過程 中，氣體自第2水箱側逆流至便器排水路内。因此，此便器 .洗淨裝置可使虹吸作用持續，而可利用虹吸作用將便斗内之 . 穢物等良好地向便器本體外排出。

Description of the Invention: [Technical Field of the Invention] The present invention relates to a toilet bowl washing device and a water-washing toilet. [Prior Art] Patent Document 1 discloses a water-washing type device having a device for knowing that the water-washing toilet is convenient! I body and toilet cleaning device. This water-washing type σ-type toilet washing device supplies washing water to the toilet body to perform toilet washing. The body II has a toilet portion and a toilet drainage path that communicates with the downstream side of the toilet portion. The toilet washing device has a tank, a hollow tube, an exhaust L road, and a water passage. The cypress system accumulates the washing water supplied to the body of the toilet. The hollow pipe is housed in the water tank so as to extend in the vertical direction, and the lower end is opened in the water tank. The exhaust passage is at a position higher than the highest water storage level of the water tank, and communicates with the upper end portion of the hollow tube and the toilet drainage path of the toilet body. The water supply system connects the water tank to the toilet part of the toilet body. When the toilet is washed, the washing water stored in the water tank is supplied to the toilet bowl via the water supply path, so that the water level in the water tank is lowered. Moreover, the water level in the hollow f is also slightly slower than the drop in the water level in the water tank. Because of this, the hollow tube draws gas from the toilet drainage channel via the air passage. • If the toilet is washed, the washing water supplied to the toilet bowl will flow into the toilet drain, and the hollow tube will suck the gas in the toilet drain. Therefore, it can be washed less. The purified water creates a siphon effect in the toilet drainage channel. Therefore, the flush toilet can be discharged to the outside of the toilet body by using the siphon action generated in the toilet drainage path 10Π03989 3 201237238. Further, Patent Document 2 discloses a flush toilet having another conventional toilet washing device. The flush toilet is provided with a toilet body and a toilet washing device. This water laundering H-money cleaning device supplies the washing water to the toilet body to perform the toilet washing. The toilet washing device is provided with a water tank and a jet (10) pump) for the forest. Water is difficult, and the miscellaneous water is supplied to the body. The jet pump has a mouth (no cut) disposed at a position opposite to the nozzle with a gap therebetween. The spray (4) is disposed so as to sink in the washing water in the water tank. The container is formed in such a manner that the upper end is lower than the highest water level of the washing water in the water tank. Further, the container has an opening that is disposed at the side and a switch cover for opening and closing the opening. And the toilet body. If the washing toilet sprays the washing water from the nozzle of the toilet washing device, the washing water attracts the washing water of the mouth to flow into the throat of the human body. Thus, the water can be supplied to the body through the water supply path. The washing water, plus & washing water attracted by the jet washing water, can increase the flow rate (the volume of the fluid moving per unit time, the same below). Moreover, the flushing toilet is replaced by a switch cover. The opening of the switch disposed on the side of the container of the toilet washing device can increase or decrease the amount of the washing water supplied to the toilet body. That is, the washing water outside the container can be opened through the opening when the opening of the container is opened. Therefore, the washing water outside the container can also be sucked by the mouth pump, and can be supplied to the toilet body via the water supply path. 101103989 4 201237238 On the other hand, the opening of the container is closed by the switch cover. If the water level of the washing water in the water phase becomes equal to the upper end of the container, at this point of time, the washing water outside the grain thief will not flow into the container. Therefore, the water level of the washing water in the water tank becomes After the upper ends of the containers are equal, only the washing water in the container may be sucked by the jet pump and supplied to the toilet body via the water supply path. As described above, the washing will be performed in a state in which the opening that is disposed on the side of the container is opened. When the clean water is supplied to the toilet body in the state in which the water is supplied to the toilet body by the switch cover, the amount of water that can be supplied to the toilet body is reduced. Therefore, the toilet wash is reduced. The net device can be used for washing the toilet with a large amount of washing water (large washing) and washing with a small amount of washing water (small washing). [Prior Art Document] [Patent Literature] Patent Document 1: Patent Open Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. 2004-156382. The Jc position of the purified water is maintained at a level slightly higher than the water level of the washing water in the water tank (the state in which the water level difference between the water tank and the middle tank is small). Therefore, the hollow tube is pumped from the open σ. Until the end, the gas in the toilet drainage channel is sucked with a weak suction force. Therefore, the water-washing toilet has a hollow tube which is not good. Pomelo 101103989 201237238 Suction is a gas manifold drainage channel in the drainage road The inner siphon action is generated and sustained. That is, because the suction force of the hollow tube is weak, there is a siphoning in the toilet drainage channel (10), and the inside of the water channel is after the π and the action. 'There is a negative pressure in the toilet drainage path becomes stronger than the suction force of the hollow 1', so that the gas flows back into the n-drainage path and the siphon action is terminated early. Therefore, in the case of the water-washing type, it is impossible to discharge the contents in the toilet bowl portion by performing the washing of the toilet. The first invention and the second invention are solved by the above-mentioned facts, and the object of the present invention is to provide a toilet washing apparatus capable of performing toilet washing and a flush toilet equipped with the toilet washing apparatus. . Further, in the flush toilet of Patent Document 1, if the shape of the toilet bowl or the toilet drainage path is different, there is a case where the flow rate of the washing water supplied to the toilet portion is the same, and the flow rate of the washing water of the toilet drain is also Not the same situation. The flow rate of the washing water in the toilet drain pipe affects the suction force of the gas in the drain pipe of the hollow pipe suctioning device and the discharge force of discharging the waste in the toilet bowl portion. Therefore, in the toilet body in which the flow rate of the washing water in the toilet drainage path is large, there is a suction force in which the suction force of the suction pipe in the hollow pipe is excessively strong, and the waste flowing in the toilet drainage path is present. Suction into the exhaust passage. If the exhaust passage is blocked by the dirt sucked into the discharge passage, there is a possibility that the siphon action is not well generated in the toilet drainage passage during the subsequent toilet cleaning. On the other hand, in the toilet body in which the flow rate of the washing water in the toilet drainage path is small, there is no flaw in sucking the waste into the exhaust passage, but there is a presence or absence of 101103989 6 201237238. The siphon action is generated, which causes the discharge force of the stool to be discharged to the outside of the body to be lowered. When the shape of the toilet bowl or the toilet drainage path is different, the toilet can not be easily discharged by performing the toilet washing and discharging the contents in the toilet bowl. According to a third aspect of the invention, in view of the above-described conventional circumstances, it is an object of the invention to provide a toilet washing apparatus which can perform toilet washing well and a flush toilet which is provided with the toilet washing apparatus. Further, in the flush toilet of Patent Document 2, in order to cause the toilet washing device to suck the washing water in the water tank by the spray pump, it is necessary to prevent the water from being immersed in the washing water in the water tank. Therefore, in order to effectively use the washing water accumulated in the water tank for the washing of the bowl, it is necessary to arrange the spray pump in the vicinity of the bottom surface of the water tank. When the spray pump is disposed in the vicinity of the bottom surface of the water tank and the water tank is disposed at a position lower than the upper surface of the toilet body, there is a long water supply path connecting the spray pump and the toilet body, and the rising slope of the water supply path虞^If the water supply path becomes longer, or the rising slope of the water supply path becomes steeper, the washing water passing through the water supply path will increase the inconvenience loss, and the flow rate of the washing water supplied to the toilet body will decrease. There is a flaw in the washing of the toilet. The fourth invention is completed by the above-mentioned actual situation, and should be solved. The simple invention is to provide a toilet cleaning device having a degree of freedom of setting position and capable of performing toilet cleaning, and the toilet is provided. Washing device for washing device. 101103989 201237238 (Means for Solving the Problem) The toilet washing device according to the first aspect of the present invention is characterized in that the washing water is supplied to the toilet body having the toilet portion and the toilet drainage path on the downstream side of the toilet portion. " ' the first water tank for accumulating the washing water; the second water tank having the lower opening communicating with the first water tank, and increasing the water storage amount per unit height in the upper region compared to the lower region; a ventilation passage that communicates with the second water tank and the toilet drainage channel at a position higher than a highest water storage level of the first water tank; a water supply passage that communicates with the first water tank and the toilet portion; and a delay device The timing of supplying the washing water accumulated in the upper tank to the cashmere unit is started at the timing of the supply of the washing water accumulated in the upper tank through the water supply passage, and the flow rate of the ventilating flow to the second tank side from the toilet drain side is maximized. In the toilet cleaning device, the water stored in the second water tank is supplied to the toilet bowl via the water supply path, thereby performing the washing of the toilet. At this time, the first water tank is lowered by the lowering of the water level in the second rape. (4) The gas path is reduced to water = gas. Therefore, even a small amount of water can also produce a siphon effect in the toilet drainage channel, and the waste in the toilet can be discharged well. Since the device is slower at the start of the toilet washing by the material device, the flow rate of the gas flowing from the side of the toilet drainage channel in the Tongguan-Tongli Road to the 101103989 1 tank side is maximized, so that the second can be made. The water level in the water tank is delayed by 201237238. Therefore, the water level in the &/ period water tank in the second tank will decrease rapidly. The water level difference will increase. The first tank will be in the first tank and the second tank. The difference between the water level in the suction tank of the second tank and the water level in the second tank is proportional to the suction force and strength of the force. Therefore, the '2nd tank can be interesting. This toilet washes the heart: the gas pumping drainage channel The gas inside. Therefore, the siphon effect is generated in the toilet drainage channel. / I♦ The device makes the second tank more than the corporal corps in the upper area. Therefore, even by the delay device The toilet drain side # "k wire is set to the maximum, and (4) Ί 2 The gas flow rate in the air passage on the tank side is '2. The washing water in the water tank flows out to the first tank = large flow rate = 2nd condition The water level in the water tank also slowly drops. Therefore, the difference between the water level in the first tank and the second tank is not drastically reduced. Therefore, the toilet washing device can maintain the strong suction force of the second tank. In this way, the toilet washing device can prevent the siphoning force in the toilet drain path from being maintained for a long time so that the suction force of the second water tank is stronger than the negative pressure in the toilet water moving path, thereby preventing the siphon In the continuous process, the gas flows back from the second tank side to the toilet drain. Therefore, the toilet washing device can continue the siphon action, and the siphon can be used to discharge the contents of the toilet bowl and the like to the outside of the toilet body. Therefore, the toilet washing apparatus of the first invention can perform the toilet washing well. In the toilet cleaning device according to the second aspect of the invention, the washing water is supplied to the toilet body having the toilet portion and the toilet drain passage connected to the downstream side of the toilet portion, 101103989 9 201237238, which is characterized in that: Accumulating the washing water, and reducing the amount of water per unit in the upper & area compared to the lower area; the second tank 'the lower opening is connected to the first tank. The air passage is through the first tank a position where the highest water storage level is high, and the second water tank and the toilet drainage channel are connected; the delay I describes the first water tank and the toilet portion; and the washing of the water tank is started by the water supply path. When the supply of the water passage to the toilet portion is performed, the flow rate of the gas in the Weilu from the second tank side of the toilet bowl is increased. The toilet washing device secretly supplies the washing water supplied from the forest to the toilet bowl to perform washing of the toilet. At this time, the second tank is used to suck the gas in the toilet drainage path through the air passage by the drop in the water level in the second tank. Therefore, even if a small amount of washing water can generate a rainbow effect in the toilet drainage path, the spikes in the toilet can be discharged well. In addition, since the toilet cleaning device is slower at the time of starting the toilet washing by the delay device, the flow rate of the gas flowing to the second tank side from the toilet drainage path side in the air passage is maximized, so that the 2 The water level in the water tank is delayed. Therefore, during this period, the water level in the third tank will drop faster than the water level in the second tank, and the water level difference between the second tank and the second tank will be increased. In particular, since the toilet cleaning device has a lower water storage capacity per unit height in the upper area of the '01103989 10 201237238, the water tank can be cleaned in the first water tank if it is washed. The water level has dropped sharply. Therefore, the water level difference between the water tank and the second water tank becomes large, and the second water tank can have a strong suction force, so that the gas in the toilet drainage channel can be sucked in one breath. Therefore, the toilet cleaning device It can be used to make the rainbow in the toilet drainage path. In addition, the toilet cleaning device is such that the second tank sucks the wide area of the toilet drainage channel and causes the washing water to flow out into the first water tank, but the livestock water per unit degree of the area below the first water tank I More than the upper area, the water level in the first water phase caused by the washing water can be reduced. Therefore, it is possible to suppress a decrease in the water level difference between the first tank and the second tank, and it is possible to suppress a decrease in the suction force of the second tank. Therefore, the toilet washing device can maintain the strong suction force of the second tank. In this way, since the toilet washing device can maintain the state in which the negative pressure in the toilet drainage path caused by the siphon action generated in the toilet drainage channel is maintained for a long time, the siphon can be prevented from siphoning. During the continuous process, the gas flows back from the second tank side to the toilet drain. Therefore, the toilet device can continue the siphon action, and the siphon can be used to discharge the contents of the toilet bowl to the outside of the toilet body. According to the second aspect of the present invention, the toilet washing apparatus can perform the toilet washing well. A toilet bowl 101103989 201237238 having a toilet bowl portion and a toilet bowl main body that communicates with the toilet drain passage on the downstream side of the toilet bowl portion and the toilet washing device of the first invention or the second invention is provided as described above. The siphon effect, and the siphon effect. Therefore, the flush toilet can use the siphoning action to discharge the contents of the toilet bowl and the like well to the outside of the toilet body. Therefore, the flush toilet can be well washed in the toilet. In the toilet cleaning device of the third aspect of the invention, the washing water is supplied to the toilet body having the toilet portion and the toilet drain passage connected to the downstream side of the toilet portion, and is characterized in that: the first water phase is provided; There is a washing water flowing into the washing water for inflow; the second tank 'connects to the lower portion of the first tank; the air passage 'connects the second water tank with the above-mentioned water passage; the water supply road is connected to the above The first water tank and the toilet portion; and a washing water control device that controls a flow rate of the washing water supplied from the first water tank to the toilet portion. In the toilet cleaning device, the washing water control device controls the washing water supplied from the first tank to the toilet bowl according to the shape of the toilet bowl and the toilet bowl & That is, when the amount of washing in the toilet drainage path is clearer, the flow rate of the washing water supplied to the toilet portion can be reduced to prevent the object from being sucked into the air passage. In this way, the 'second water tank can pump the gas in the drainage road, and * can be surely in the situation where the flow of the washing water in the rainbow draining road is small when the water is drained (4). The flow rate of the washing water supplied by the department can surely discharge the siphon effect in the toilet. Therefore, the toilet washing apparatus can use the siphon as 101103989 12 201237238 to discharge the stolen goods and the like well to the outside of the toilet body. Therefore, the toilet washing apparatus of the third invention can perform toilet washing in a good manner. The toilet body having the toilet portion and the toilet drain pipe connected to the toilet portion and the toilet bowl of the third invention can be used to reliably perform the siphon action as described above. Therefore, the flush toilet can utilize the absorbing action to discharge the contents of the toilet bowl and the like to the center. Therefore, the flush toilet can be washed and cleaned in a good manner. A toilet washing apparatus according to a fourth aspect of the present invention is characterized in that: the first Μ 'there is a secret water', and the third water tank has a self-cleaning water; The inlet of the lower portion of the first water tank flows into the washing water, and the money is disposed above the π of the toilet body, and the money is supplied to the (9) of the toilet body, and when the washing water is supplied to the toilet body, the air is not self-contained. The water tank is maintained in a full water state by the water pressure of the inner washing water in a state in which the water tank is flowing, and the spray water spring has the third water tank. a nozzle that is disposed at a position opposite to the outflow σ(4) gap and that ejects the washing water toward the outflow port; and a water supply path that communicates with the outlet port and the toilet body. The toilet washing device sets the flow person α of the third water tank so that the washing water can flow from the lower portion of the first water tank into the third water tank. Therefore, before the water level of the washing water in the i-th tank drops below the red port of the third tank, the air does not flow from the first tank to the third tank through the stream. Therefore, the third tank can maintain the washing water in a full water state due to the water pressure of the washing water in the i-th tank. That is, it is possible to allow most of the washing water in the first tank to flow into the third tank. The toilet washing device can supply the washing water in the third tank through the water supply path to the toilet body 1 by the spray system, and the toilet washing device can supply a large amount of force water to the toilet body. > Here, the toilet washing apparatus can use most of the washing water stored in the 1st 7jc tank and the third, and the toilet can be cleaned well. In addition, even if the jet pump is disposed in the upper portion of the third tank, the toilet tank cleaning device can also use the washing water to drain the third tank during the period in which most of the washing water in the first tank flows into the third tank. The water is maintained in a full water state. Therefore, during this period, the jet pump can suck the washing water in the third tank, and the washing water can be sent to the water supply road. Further, since the jet pump can be disposed in the upper portion of the third tank, the toilet water washing device (the first tank and the third tank, etc.) can be disposed at a position lower than the upper surface of the toilet body, and the water supply path does not change. Long, again, the rising slope of the water supply road will not be steep. Therefore, the pressure loss of the washing water passing through the water supply path can be reduced. Therefore, the toilet washing device can supply a large amount of washing water to the toilet body. Further, the toilet washing apparatus can supply most of the washing water stored in the first tank and the third tank to the toilet body. Therefore, the toilet washing apparatus of the fourth invention has a degree of freedom in the installation position, and the toilet can be washed satisfactorily. 101103989 14 201237238 Further, the "washing toilet having the toilet body and the toilet washing device of the fourth invention" can arrange the toilet washing device at a position lower than the upper surface of the toilet body as described above, and the washing water can be satisfactorily Supply to the toilet body. Therefore, the flush toilet has a degree of freedom in setting the position of the toilet washing device, and the toilet can be washed well. [Embodiment] A preferred embodiment of the first invention and the second invention will be described. In the first tank of the first aspect of the invention, the amount of water stored in the parent unit can be reduced in the upper region compared to the lower region. In this case, since the toilet washing device has a smaller amount of water per unit height in the upper portion of the first tank than in the lower region, the water level in the first tank can be drastically lowered when the toilet washing is started. Therefore, the toilet cleaning device can increase the water level difference between the first water tank and the second water tank from the initial stage of the gas in the drain passage of the toilet tank, so that the second water tank can have a strong suction force. Pump the gas in the toilet drain. Further, in the toilet cleaning device, the second tank sucks the gas in the toilet drainage channel and causes the washing water to flow out into the first tank, but the water storage amount per unit height in the lower region of the first tank is higher than that in the upper tank. In the area, it is possible to reduce the increase in the water level in the water tank and the second tank due to the increase in the water level of the water (4) caused by the washing water, and to suppress the suction force reduction of the second tank. In particular, the water level of the second water can be gradually lowered and the water level in the i-th tank can be increased by combining with the second water tank in which the amount of water stored per unit in the upper area is higher than that in the lower area. , Ke Wei 101103989 201237238 holding the charge of the water tank in the tank and the second tank in the second tank or the second tank state of the second invention. In the case of the lowest water level of the first water tank, the vehicle, (4) is lower than this, and the second water is connected to the first water tank. The gas (odor) in the drain passage of the first inner toilet is discharged to the door through the air passage to be installed in the air passage and the water passage: between the opening and closing of the air passage. In this case, the second tank can be sucked into the toilet via the air passage by opening the ρ· _ at a timing slower than when the supply of the i-th water-washed water bucket portion is started via the supply path. Gas inside. Thus, by controlling the closing of the switch, it is possible to easily control the timing at which the second tank starts to suck the gas in the toilet drainage path. In this case, the device cleaning device can accurately suck the gas in the toilet drainage channel for siphoning in the toilet drainage channel. The second tank of the first invention or the second invention can be housed in the first tank. In this case, the communication between the first tank and the second tank can be completed by merely accommodating and fixing the second tank in the j-th tank. Therefore, it is not necessary to connect the components of the first tank and the second tank. Further, it is possible to eliminate the occurrence of water leakage from the joint portion between the i-th water tank and the second water tank. Next, the first embodiment and the first embodiment of the present invention will be described with reference to the drawings and the first embodiment of the present invention, and the description of the first embodiment and the second embodiment of the present invention. <Example 1> As shown in Fig. 1, the water-washing toilet apparatus of the first embodiment, the toilet body 10, and the toilet bowl 20 for supplying the washing water to the toilet body 10 are provided.

第2水箱22係為空洞，且具有於外殼部22A之上端面連 接有通氣路23之一端部之連通口 22B、以及使下端朝向下 方開口之下部開口 22C。又，第2水箱22係使外殼部22A 10Π03989 17 201237238 之上部相較於下部朝水平方向之一方向擴大。因此’第2 水箱22係形成為於上方區域22U内每單位高度之蓄水量多 於下方區域22D。此第2水箱22係以使外殼部22A之上表 面成為與第1水箱21之最高蓄水位L大致相同高度之方 式，收納且固定於第1水箱21内。第2水箱22係使下部開 口 22C於第1水箱21内開口。因此，帛2水箱22可自下 部開口 22C流入洗淨水，而以與第丨水箱21相同之水位蓄 積洗淨水。如此，可藉由僅將第2水箱22收納且固定於第 1水箱21内就完成第1水箱21與第2水箱22之連通。因 此’不需要連結第1水箱21與第2水箱22之構件，而可消 除來自第1水箱21與第2水箱22之連結賴產生之漏水之 虞。 將外殼部22A之上部相較於下部朝水平方向擴大之第2 水箱22收納且固定於第i水箱21之内部，藉此使第i水箱 21相較於下方區域21D在上方區域21U内減少每單位高度 之蓄水量。 通氣路23係將-端部連接於第2水箱22之連通口咖， 自第1水箱21之上端開口朝便器本體1〇側延伸，且將另一 端部連接於較水封部13位於下游側之便轉水路η之上 部。因此，通氣路23係經由較第！水箱21之最高蓄7立乙 高之位置連通第2水箱22與便器排水路12。通：水2= 於中途設置有作為延遲裝置之開閉閥25。開閉閥Μ藉由未 101103989 201237238 圖示之控制裝置進行開關控制’可用以開關通氣路23。 供水路24係將一端部連接於第1水箱21之排水口 21C， 將另一端部配置於便器本體10之便斗部1丨之後部，且以沿 著便器本體10之便斗部11之上部周緣噴出洗淨水之方式形 成噴水口 24A。因此，自噴水口 24A噴出之洗淨水可沿著 便斗部11之表面朝一方向流動，於便斗部11内形成旋流。 供水路24係於中途設置有將蓄積於第1水箱21之洗淨水向 便斗部11側加壓輸送之泵！^此泵p具有可增減加壓輸送 洗淨水之流量之流量調整功能。 接著’對具有上述構成之水洗式便器之便器洗淨步驟進行 說明。 此水洗式便器係於便器洗淨前之待機狀態下，如圖1所 示’使第1水箱21蓄積洗淨水至最高蓄水位l為止。又’ 第2水箱22係蓄積洗淨水達到與第1水箱21内相同之水 位。於此待機狀態下，設置於通氣路23之開閉閥25及設置 於水箱用供水路26之供水用閥26V係為閉閥。便器本體10 係將洗淨水蓄積於水封部13，形成水封。 水洗式便器當操作未圖示之便器洗淨按鈕時，泵P就會運 轉，並開始進行便器洗淨。如圖6所示，泵p係於運轉初期 (0〜tl秒），一面緩慢增加流量一面將洗淨水向便斗部11側 加壓輸送。藉此，可進行泵P内之排氣，避免發出氣體攪拌 聲。又，如圖2所示，第1水箱21由於在上方區域21U内 101103989 19 201237238 每單位高度之蓄水量少於下方區域21D，因此第丨水箱 21内之水位會一口氣下降’形成第1水箱21内與第2水箱 22内之水位差。又，便器本體10之便斗部u /内水位會1 升。 若經過tl㈣，栗P使加壓輸送之洗淨水之流量增加至 ql(L/min)為止(tl秒〜12秒）。如此一來，首先，如圖^示， 自便器本體H)之水封部13溢流至便器排水路12下游側之 洗淨水之流量亦增加。又，第丨水箱21内水位進—步下降， 使第1水箱21内與第2水箱22内之水位差進一步變大。藉 此，第2水箱22可產生用以自便器排水路12抽吸氣體所; 之抽吸力。 而且，藉由泵P持續進行運轉，如圖4所示，自便器本體 1〇之水封部13溢流至便器排水路12下游側之洗淨水係於 便賴水路12之下游部形成水膜，將便器排水_之下游 此狀態下’便器洗淨裝置2。使設置於通氣路η 25開閥。如此-來，由於氣體可於通⑽内自 便排水路12側流向第2欢 22内水位之下降，第9二因此’伴隨第2水箱 之氣體。即，開閉閱 第1水箱21之洗淨水_由供水路24 _將蓄積於 便器洗淨)時更慢之時機開^部U供:給㈣？運轉而開始 2水箱22側之通氣路:’使自便器排水路12側流向第 __ 内之氣《量成為最大之延遲裝 20 201237238 又，由於此便器洗淨裝置20係藉由開閉_之開闕，使 第2水箱22 P絲進行便器排水路12内之氣體抽吸者，因 此，藉由控制開閉閥25之開閥，可交且α〜妨 ^ J办易地控制第2水箱22 開始抽吸便器排水路12内之氣麫夕吐地 〆 虱體之時機。因此，此便器洗 淨裝置20可確切地抽吸便器排k败 文益徘水路12内之氣體，用以使便 器排水路12内產生虹吸作用。 藉由形成於便器排水路12下游部之水膜而於便器排水路 12内形成封閉空間，使第2水箱2 2抽吸此封閉空間内之氣 體°因此’由於此水洗式便11可自便11排水路12内確實地 減少氣體，所以，即便是少量之洗淨水，亦可在便器排水路 12内產生虹吸作用。The second tank 22 is hollow, and has a communication port 22B to which one end portion of the air passage 23 is connected to the upper end surface of the outer casing portion 22A, and a lower portion opening 22C toward the lower opening. Further, the second tank 22 expands the upper portion of the outer casing portion 22A 10Π03989 17 201237238 in one direction in the horizontal direction from the lower portion. Therefore, the second water tank 22 is formed such that the water storage amount per unit height in the upper region 22U is larger than the lower region 22D. The second tank 22 is housed and fixed in the first tank 21 such that the upper surface of the outer casing portion 22A has substantially the same height as the highest water storage level L of the first water tank 21. The second tank 22 opens the lower opening 22C in the first tank 21. Therefore, the 帛2 water tank 22 can flow into the washing water from the lower opening 22C, and the washing water is stored at the same water level as the third water tank 21. Thus, the communication between the first tank 21 and the second tank 22 can be completed by merely accommodating and fixing the second tank 22 in the first tank 21. Therefore, it is not necessary to connect the members of the first water tank 21 and the second water tank 22, and the water leakage from the connection between the first water tank 21 and the second water tank 22 can be eliminated. The upper portion of the outer casing portion 22A is housed and fixed to the inside of the i-th water tank 21 with respect to the second water tank 22 whose lower portion is enlarged in the horizontal direction, whereby the i-th water tank 21 is reduced in the upper region 21U from the lower region 21D. The amount of water stored per unit of height. The air passage 23 connects the end portion to the communication port of the second tank 22, and extends from the upper end opening of the first tank 21 toward the side of the toilet body 1 and connects the other end portion to the downstream side of the water seal portion 13. It turns to the upper part of the waterway η. Therefore, the air passage 23 is via the first! The water tank 21 is connected to the second water tank 22 and the toilet drainage path 12 at a position where the water tank 21 is at the highest level. Pass: Water 2 = An on-off valve 25 as a delay device is provided in the middle. The opening and closing valve 开关 is controlled by a control device not shown in 101103989 201237238 'can be used to open and close the air passage 23 . The water supply passage 24 connects one end portion to the drain port 21C of the first tank 21, and the other end portion to the rear portion of the toilet bowl portion 10 of the toilet body 10, and the upper portion of the toilet bowl portion 11 along the toilet body 10. The water spout 24A is formed by spraying the washing water around the circumference. Therefore, the washing water sprayed from the water spout 24A flows in one direction along the surface of the bowl portion 11, and a swirl flow is formed in the bowl portion 11. The water supply passage 24 is provided with a pump for pressurizing and conveying the washing water stored in the first tank 21 to the side of the bowl portion 11 in the middle of the water supply passage 24! ^ This pump p has a flow adjustment function that can increase or decrease the flow rate of the pressurized delivery washing water. Next, the toilet washing step of the flush toilet having the above configuration will be described. This flush toilet is placed in the standby state before the toilet is washed, as shown in Fig. 1 to cause the first water tank 21 to accumulate the washing water to the highest water storage level l. Further, the second tank 22 accumulates the washing water to the same level as that in the first tank 21. In the standby state, the opening and closing valve 25 provided in the air passage 23 and the water supply valve 26V provided in the water supply passage 26 for the water tank are closed. The toilet body 10 accumulates the washing water in the water seal portion 13 to form a water seal. Washing toilet When the toilet washing button (not shown) is operated, the pump P will be operated and the toilet will be washed. As shown in Fig. 6, the pump p is pressurized at the initial stage of operation (0 to tl seconds), and the washing water is pressurized to the side of the toilet portion 11 while gradually increasing the flow rate. Thereby, the exhaust in the pump P can be performed to avoid the sound of gas agitation. Further, as shown in FIG. 2, since the first tank 21 has a water storage amount per unit height in the upper region 21U of 101103989 19 201237238, the water level in the second tank 21 is lowered in one breath, and the first water tank 21 is formed. The water level in the water tank 21 and the second water tank 22 are different. Moreover, the toilet bowl u/inner water level of the toilet body 10 will be 1 liter. If tl (four) is passed, the pump P increases the flow rate of the pressurized washing water to ql (L/min) (tl seconds to 12 seconds). As a result, first, as shown in the figure, the flow rate of the washing water overflowing from the water seal portion 13 of the toilet body H) to the downstream side of the toilet drain passage 12 is also increased. Further, the water level in the second tank 21 is gradually lowered, and the water level difference between the inside of the first tank 21 and the second tank 22 is further increased. Thereby, the second water tank 22 can generate a suction force for sucking gas from the toilet drainage path 12. Further, as the pump P continues to operate, as shown in FIG. 4, the washing water overflowing from the water seal portion 13 of the toilet body 1 to the downstream side of the toilet drain passage 12 is formed in the downstream portion of the water passage 12 to form water. The membrane, the toilet is drained _ downstream of this state, the toilet cleaning device 2. The valve is placed in the air passage η 25 to open the valve. In this way, since the gas can flow in the passage (10) from the side of the drain passage 12 to the water level in the second heater 22, the ninth step is accompanied by the gas in the second tank. In other words, when the washing water of the first tank 21 is opened and closed, the water supply passage 24_ is stored in the toilet to be washed, the timing is slower. In the operation, the air passage on the side of the water tank 22 is started: 'the air flowing into the first __ from the side of the toilet drain 12 is the largest delay pack 20 201237238, and the toilet cleaning device 20 is opened and closed. The second water tank 22 P wire is opened to allow the gas in the toilet drainage channel 12 to be sucked. Therefore, by controlling the opening and closing of the opening and closing valve 25, the second water tank 22 can be easily controlled. At the beginning of the suction of the toilet drainage channel 12, the timing of the gas smashing the body is started. Therefore, the toilet washing device 20 can accurately suck the gas in the toilet bowl 12 to cause the siphon action in the toilet drainage path 12. The closed space is formed in the toilet drainage channel 12 by the water film formed in the downstream portion of the toilet drainage path 12, so that the second water tank 22 draws the gas in the closed space. Therefore, the water washing type 11 can be used freely. Since the gas is surely reduced in the drain passage 12, even a small amount of washing water can cause a siphon action in the toilet drain passage 12.

V s作為延遲裝置之開閉閥25係於較開始進行便器洗淨 慢之時機開閥，藉此，於該期間内使第i水箱21内之水位 下降’可與第2水箱22内之水位形成較大之水位差。由於 第1水相21内與第2 7jc箱22内之水位差之大小係與第2 水鈿22之抽吸力之強弱成比例’所以可使第2水箱22具有 強力之抽吸力。因此，第2水箱22可—口氣抽吸便器排水 路12内之氣體。因此，此便器洗淨裝置2〇可確實地使便器 排水路12内產生虹吸作用。 在泵P進一步運轉，與第2水箱22内水位下降之同時， 第2水4 22持續抽吸來自便器排水路Η内之氣體。此時， 101103989 21 201237238 雖然第2水箱22内之洗淨水以大流量流出至第1水箱21 内，但由於使第2水箱22於上方區域22U内每單位高度之 蓄水量多於下方&域22D ’故第2水箱22内之水位會緩慢 地下降。 又，由於第1水箱21之下方區域21D每單位高度之蓄水 量多於上方區域21U ’故藉由自第2水箱22流出至第1水 箱21内之洗淨水可減少第1水箱21内水位之上升。如此， 此便器洗淨裝置20由於可使第2水箱22内之水位缓慢下 降，且減少第1水箱21内之水位上升，故可維持充分地確 保第1水箱21内與第2水箱22内之水位差之狀態。即，第 2水箱22可自最初長時間地以較強之抽吸力抽吸便器排水 路12内之氣體。 如此，由於此便器洗淨裝置20可長時間維持在第2水箱 22之抽吸力較由便器排水路12内產生之虹吸作用所導致之 便器排水路12内之負壓力強之狀態，故可防止於虹吸作用 在持續之過財，⑽自第2水箱22側逆絲便器排水路 12内。因此，此便器洗淨裝置20可使虹吸作用持續。 又此便器洗淨裝置20，如圖5所示，在便器排水路12 内之洗淨水為大致滿水狀態，且便器排水路12内之負壓力

而使虹吸作用結束。 在虹吸作用結束之後，為了將洗淨水蓄積於便器本體10 之水封部13内而進行水封，於以小流量q3(L/min)將洗淨水 供給至便斗部11内之後，HP停止而結束便器洗淨⑽秒 〜t5秒）。又’使没置於水箱用供水路26之供水用闊斯 開閥，將洗淨水蓄積於第1水箱21内。其後，當第丨水箱 21内洗淨水之水位達到最高蓄水位L，且第2水箱22内之 水位達到與第1水箱21内相同之水位時，使供水用闊26v 閉閥，亦使设置於通氣路23之開閉閥25閉閥。藉此，水洗 式便器如®1 1所示’恢復至便器洗淨前之待機狀態。 第1水箱21内之水位雖會因^進行運轉執行便器洗淨 101103989 23 201237238 而下降’但不會低於第2水箱22之下部開口 22C。即，第 2水箱22係以使下部開口 22C在低於第1水箱21之最低蓄 水位之高度對第1水箱21開口之方式配置。因此，第2水 相22之下部開口 22C在平常時會由蓄積於第1水箱21内 之洗淨水所封閉，而未於第1水箱21内開放，因此，可確 實地防止便器排水路12内之氣體（臭氣)經由通氣路23放出 至第1水箱21内。 <實施例2> 如圖7所示，實施例2之水洗式便器與實施例1不同之處 在於便器洗淨裝置30具備有第3水箱32,且利用噴射泵幻

101103989 29 201237238 之水位會進一步下降，使第1水箱31内之洗淨水之水位低 於第3水箱32之流入口 32A ,。如此一來’空氣將自第1水 箱31經由第3水箱32之流入口 32A流入第3水箱32内， 使第3水箱32内洗淨水之水位一口氣下降。因此’喷射泵 33會於第3水箱32内露出，而使噴射泵33無法吸引洗淨 水。如此一來’對便斗部11内所供給洗淨水之流量就會減

第丄發明及第2發明並不限定於由上述記述及圖式所說明The opening and closing valve 25, which is a delay device, is opened at a timing when the toilet is washed slowly, whereby the water level in the i-th tank 21 is lowered during the period to form a water level in the second tank 22. Larger water level difference. Since the magnitude of the water level difference between the first water phase 21 and the second water tank 22 is proportional to the strength of the suction force of the second water hammer 22, the second water tank 22 can be made to have a strong suction force. Therefore, the second tank 22 can suck the gas in the toilet drain 12 in the mouth. Therefore, the toilet washing device 2 can surely cause a siphon action in the toilet drainage path 12. When the pump P is further operated and the water level in the second tank 22 is lowered, the second water 4 22 continues to suck the gas from the toilet drain. At this time, 101103989 21 201237238, the washing water in the second tank 22 flows out into the first tank 21 at a large flow rate, but the amount of water stored per unit height in the upper region 22U of the second tank 22 is higher than that of the lower &; Domain 22D 'The water level in the second tank 22 will slowly drop. Further, since the amount of water stored per unit height in the lower region 21D of the first tank 21 is larger than that in the upper region 21U', the washing water flowing out of the second tank 22 into the first tank 21 can be reduced in the first tank 21 The rise in water level. In this way, the toilet cleaning device 20 can gradually reduce the water level in the second tank 22 and reduce the water level in the first tank 21, so that the inside of the first tank 21 and the second tank 22 can be sufficiently ensured. The state of the water level difference. That is, the second tank 22 can suck the gas in the toilet drain 12 with a strong suction force for a long time from the initial time. In this way, the toilet cleaning device 20 can maintain the state in which the suction force of the second water tank 22 is stronger than the negative pressure in the toilet drainage path 12 caused by the siphon action generated in the toilet drainage path 12 for a long time. It is prevented from siphoning in the past, and (10) is reversed from the second water tank 22 side in the flush toilet drainage channel 12. Therefore, the toilet washing device 20 can continue the siphoning action. Further, as shown in Fig. 5, the toilet washing device 20 is in a state where the washing water in the toilet draining passage 12 is substantially full and the negative pressure in the toilet draining passage 12 is maximum, if the i-th tank 21 is in the state where the negative pressure in the toilet draining passage 12 is maximum. The water level f in the inside and the second water tank U is reduced by 'heart. Figure 6 shows 'will hide? The flow of the pressurized washing water is further increased to q2 (L/min) (t2 seconds to t3 seconds). As a result, since the flow rate of the washing water flowing out from the first water if 21 into the toilet bowl U is increased, the washing water flowing out from the second water tank 22 to the i-th water tank 21 can be used. Prevent the water level of the first tank 21 from rising, thus preventing the first! The water level difference between the water tank 2m and the second water tank 22 is reduced, so that the suction force of the second water tank can be maintained not weaker than the negative pressure in the toilet drainage channel 12, so that the toilet drainage channel 12 can be made The siphon action continues, and the limb-absorbing action discharges the foreign body of the toilet body 10 well. Therefore, the flush toilet of the first embodiment can perform the toilet washing well. By reducing the flow rate of the washing water pressurized by the pump ρ at t3 seconds to t4 seconds, the η-like washing water in the toilet bowl portion is reduced, and the water level in the toilet bowl portion n is lowered. Thereby, the air is caused to flow into the toilet drainage path 12 from the side of the toilet bowl u, and the siphon action is ended. After the completion of the siphoning operation, the water is sealed in the water seal portion 13 of the toilet body 10, and the washing water is supplied to the toilet bowl 11 at a small flow rate q3 (L/min). Stop and end the toilet wash (10) seconds ~ t5 seconds). Further, the water supply valve that is not placed in the water supply path 26 for the water tank is opened, and the washing water is stored in the first water tank 21. Thereafter, when the water level of the washing water in the third water tank 21 reaches the highest water storage level L, and the water level in the second water tank 22 reaches the same water level as in the first water tank 21, the water supply is widened by 26v. The opening and closing valve 25 provided in the air passage 23 is closed. As a result, the flush toilet is restored as shown in the ®1 1 to the standby state before the toilet is washed. The water level in the first tank 21 is lowered by the operation of the toilet 101103989 23 201237238 but is not lower than the lower opening 22C of the second tank 22. In other words, the second tank 22 is disposed such that the lower opening 22C opens to the first tank 21 at a height lower than the lowest water level of the first tank 21. Therefore, the lower opening 22C of the second aqueous phase 22 is closed by the washing water stored in the first tank 21 at ordinary times, and is not opened in the first tank 21, so that the toilet drain 12 can be reliably prevented. The gas (odor) inside is discharged into the first tank 21 via the air passage 23 . <Example 2> As shown in Fig. 7, the flush toilet of the second embodiment differs from the first embodiment in that the toilet washing device 30 is provided with the third water tank 32, and is accumulated in the first water tank by the jet pump. The other components of the main body of the first embodiment are the same as those of the first embodiment, and the same components are denoted by the same reference numerals, and the detailed description thereof will be omitted. The toilet washing device 30 is disposed behind the toilet body 1 and is disposed at a position lower than the upper surface of the toilet body 1G. Therefore, this washable toilet can achieve a low profile. The toilet cleaning device 3 includes an i-th tank 第, a second tank 22, a ventilating passage 23, a water supply passage 24, an opening and closing valve 25 as a delay device, a third tank 32, and an injection pump 33. The first tank 31 is formed by a peripheral wall portion 31A that opens upward in the upper end and extends in the vertical direction, and a bottom wall portion that closes the lower end of the peripheral wall portion 31A. The first tank 31 is housed inside and is fixed to the second tank and the third tank 32. 101103989 24 201237238 The third water phase 32 has an inflow port 32A that is opened downward in the first tank 31. Further, the third tank 32 has an outflow port 32B at the upper end portion. In the third water phase 32, a branch water supply path 37 for supplying the washing water to the injection nozzle 36 to be described later is inserted in a watertight manner from the upper surface. The opening area of the outflow port 32B is formed to be larger than the opening area of the injection port 36A of the injection nozzle %. The water supply path 34 is connected to the outflow port 32B and the toilet body 1〇. This water supply path 34 continuously extends from the opening edge of the outlet 32B. Therefore, the water supply path area is formed to be larger than the opening area from the injection port 3 of the injection nozzle 36. Further, the water supply path 34 has a slope toward the upper slope of the upper end of the toilet body 1G, and the water discharge port 34A at the downstream end is used to wash the water along the periphery of the upper portion of the toilet portion u of the body 1G. Therefore, the washing water sprayed from the water spouting port 34A of the water supply path 34 can be used as a toilet. The surface of p 11 flows in one direction, and is formed in the toilet bowl 11 and 'the outlet of the third water tank 32 is formed in the third water tank 32 ^ = part', so the water supply path % does not become long, and The rising slope of 34 = steep. Therefore, the loss of the washing water passing through the water supply path 34 can be reduced. The toilet washing device % can supply a large amount of washing water to the toilet body 10 . The injection system 33 has an injection nozzle % disposed in the third tank 32 and disposed at a position opposed to the outlet 32B of the third tank 32 with a gap therebetween. The jet 7 is composed of a discharge port 32B of the third water phase 32 and a nozzle nozzle 36. 101103989 25 201237238 The injection nozzle 36 is disposed in the upper portion of the third tank 32, and the washing water is discharged toward the outlet port 32B so that the discharged washing water flows along the water supply path. Thus, the jet pump 33 is disposed above the third tank 32. The injection nozzle 36 flows into the washing water via the branch water supply path 37 that branches the water supply passage 26 for the water tank. The branch water supply passage 37 is provided with a spray nozzle valve 37V in the middle. Next, the toilet washing step of the flush toilet having the above configuration will be described. This flush toilet is in a standby state before the toilet is washed, and as shown in Fig. 7, the first tank 31 accumulates the washing water to the highest water level B. The second tank 22 accumulates the washing water to the same water level as the third tank 31. The third tank 32 is in a state of full water until the washing water flows into the water supply passage 34. In this standby state, the opening/closing valve 25 that is free from the air passage 23, the water supply valve 26V provided in the water supply path 26 for the water tank, and the injection nozzle 37V that is provided in the branch water supply path 37 are in the closed state. The toilet body 丨q accumulates the washing water in the water seal portion 13 to form a water seal. If the water-washing toilet is not cleaned, it will be washed as shown in Fig. 8. If the spray nozzle is wide, the valve will be opened and the toilet will be washed. In other words, the washing water in the third tank 3 is supplied to the toilet bowl 11 of the toilet main body 1Q via the outflow port 32 and the water supply path 34. At this time, the washing water of the toilet body 10 can be supplied to the toilet portion u of the toilet body 10 by the washing water of the flow rate of about 3 to 4 times the flow rate of the washing water from the injection port 36q. ^Beginning to start _, because the water storage capacity of the first tank in the upper area of 31U is less than the lower area, the water level of the i-th tank 31 = the gas will drop - the first tank and the second water: The water level difference inside. Also, #哭士触相22 Toilet body 10, the water level of the toilet part u-after 'If the toilet is continuously washed, as shown in Fig. 9, the water seal part 13 of 10 will overflow to cry, from The amount of the main body is also % X 1 The flow of the washing water on the downstream side of the waterway 12 will gradually decrease in the water level in the first tank 31, so that the water level difference between the heart and the second tank 22 can be diverted into the second tank 22 Tian Hao, you are a good man, this is the suction. Use the sputum from the toilet drain U to pump the gas. If you continue to wash the toilet, as shown in Figure ig, the water seal Αβ s of the body 1 is more. . The washing water on the downstream side of the η drainage passage 12 forms a downstream portion m of the k-way 12 and closes the downstream portion of the turning water passage 12. In this state, the toilet washing device 30 opens the opening and closing valve 25 provided in the air passage 23. In this manner, since the gas can flow to the second tank side from the toilet drain passage 12 side in the air passage 23, the second tank 22 sucks into the toilet drain passage 12 as the second tank 22 is lowered. gas. Further, since the toilet cleaning device 30 opens the valve by the opening and closing valve 25, the second water tank 22 starts to suck the gas in the toilet drainage path 12, so that it is easy to control the opening and closing of the opening and closing valve 25. Ground control of the second water tank 22 starts pumping 101103989 27 201237238 The timing of the gas in the toilet drain passage 12. Therefore, this will be able to clean the skirts by 3 〇 to the exact gas, and (4) to create a cylinder suction effect in the toilet drainage channel 2 . A closed space is formed in the toilet drainage channel 12 by forming a water film (4) downstream of the (10) drain passage 12, so that the second tank 22 draws the gas in the closed space. Therefore, since the flush toilet can reliably reduce the gas in the toilet drain passage 12, even a small amount of washing water can cause a siphon action in the toilet drain passage 12. Further, by opening and closing the opening and closing valve 25 as the delay device, the water level in the water tank 31 can be lowered during the period to be lower than the water level in the second water tank 22. Big water level difference. Since the difference between the inside of the first water phase 31 and the 7jc in the second tank 22 is proportional to the strength of the suction force of the second tank 22, the second tank 22 has a strong suction force. Therefore, the second water tank 22 can suck the gas in the toilet drainage path 12 in one breath. Therefore, the toilet washing device 3G can surely generate a siphon action in the toilet drainage path 12. If the toilet is continuously washed in the step-by-step manner, the water level in the second water tank 22 is lowered while the f 2 τ eye 22 continues to suck the gas from the toilet drain 12 . At this time, the washing water in the second tank 22 flows out into the first tank 31 at a large flow rate, but since the second tank 22 is in the upper region, the water storage amount per unit height is larger than that in the lower region 22D. The water level in the second tank will slowly drop. 101103989 28 201237238 Further, since the γ lower area 31D of the first tank 31 has more water per unit height than the upper area 31U, -r is the case! The water level in the first tank 31 is increased by the washing water passage flowing out of the second tank 22 into the first water tank 31. In this way, since the toilet is washed and the water is lowered, the water in the second tank 22 can be slowly lowered, and the water level in the first tank can be lowered. Therefore, the first tank 3i can be maintained and maintained. The water level difference L in the second water tank 22 is. In other words, the second tank 22 can be white #, and the gas in the drainage channel 12 is sucked for a long time from a strong suction force. In this way, the toilet cleaning device 30 can maintain the suction force of the second water tank 22 for a long period of time compared with the negative pressure in the siphon drainage passage 12 generated in the toilet drainage passage 12, so that the siphon action continues. In the process, the emulsion can be prevented from flowing back from the second tank 22 side into the toilet drain passage 12. Therefore, the second siphoning of the county can make the siphon effect continue. The toilet washing device 3 is shown in Fig. η, because the washing water in the toilet drain passage 12 is substantially full of water state' and the suction pressure of the second water tank 22 is maximized even if the negative pressure in the toilet drain passage 12 is maximized. It is also strong, so that the gas can be prevented from flowing back from the second tank 22 side to the toilet drain passage 12 during the swaying action. Therefore, the toilet washing device 30 can continue the siphon action, and the siphon can be used to discharge the contents of the toilet bowl to the outside of the toilet body 10 well. Therefore, the flush toilet of the second embodiment can perform the toilet washing well. When the toilet is further washed, the water level of the washing water 101103989 29 201237238 in the first tank 31 is further lowered, so that the water level of the washing water in the first tank 31 is lower than the inlet 32A of the third tank 32, . In this way, the air flows into the third tank 32 from the first tank 31 through the inlet 32A of the third tank 32, and the water level of the washing water in the third tank 32 is lowered. Therefore, the jet pump 33 is exposed in the third tank 32, so that the jet pump 33 cannot attract the washing water. As a result, the flow rate of the washing water supplied to the bowl portion 11 is reduced, and the water level in the bowl portion U is lowered. Thereby, air flows into the toilet drainage path 12 from the side of the toilet portion 11 to terminate the siphon action. After the completion of the siphoning operation, in order to store the washing water in the water seal portion 13 of the toilet body 10 and perform water sealing, after the washing water is supplied into the toilet bowl portion 11, the injection nozzle valve 37V is closed to close the valve. Wash the toilet. In addition, the water supply valve 26V provided in the water tank supply passage 26 is opened, and the washing water is stored in the first tank 31. Thereafter, when the water level of the washing water in the first tank 31 reaches the highest water level L, the water level in the second tank 22 reaches the same water level as in the first tank 31, and the third tank 32 becomes full. The water supply is widened to a 26V closed valve', and the opening and closing valve 25 provided in the air passage is also closed. Thereby, as shown in Fig. 7, the flush toilet will return to the standby state before the toilet is washed. Since the lower opening 22C of the second tank 22 is located below the inflow port 32A of the third tank 32, the second tank 22 is disposed such that the lower opening 22c is lower than the lowest water level of the first tank 31. The water tank 31 is open. Therefore, since the lower opening 22C of the second tank 22 is closed by the washing water accumulated in the first tank 31 at the time of storage 101103989 30 201237238, it is not opened in the first tank 31, so that the toilet drain can be reliably prevented. The gas (odor) in the road 12 is discharged into the first tank 31 via the air passage 23. In the toilet cleaning device 30, the washing water in the third tank 32 is sucked by the jet pump 33, and the washing water of a large flow rate is supplied to the toilet body. At the same time, the washing in the first tank 31 is performed. The water flows into the third tank 32 through the inflow port 32A of the third tank 32. At this time, since the washing water in the third tank 32 is affected by the water pressure of the washing water in the first tank 31, the third tank 32 is maintained in a full water state by the washing water. Therefore, since the spray system 33 can be maintained in the washing water sinking in the third tank 32, the washing water in the third tank 32 is continuously sucked, so that the large-flow washing water can be continuously supplied.

之實施例1及2，例如以下之實施例亦包含於本發明之技術 範圍中。 K (1)於實施例1及2中，雖然將外殼部之上部相較於飞 朝水平方向擴大之第2水箱收納且固定於第丨水箱之内』 藉此’使第1水箱中相較於下方區域而在上方區域内減少 單位高度之蓄水量，但村如圖12(A)及⑻所示，第^ 44未使外殼部於上下方向變形，而使第i水箱*卜7 部朝内側凹陷’藉此’相較於下方區域而在上方區域内^ 每單位高度之蓄水量。X，亦可如圖12(Q所示，於^ 101103989 201237238 鈿43之内側之上部，安裝用以相較於下方區域而在上方區 域内減少每單位高度之蓄水量之長方體之不同零件们八。 (2) 於實施例丨及2中，賴第2水箱係使外殼部之上部 相較於下部朝水平方向之一方向擴大，但如圖12(切所示， 第2水箱45亦可使外殼部之上部相較於下部朝水平方向之 左右方向等多個方向擴大。又，亦可如圖12(E)所示，第2 水箱46藉由使外殼部朝向下方逐漸朝内側收縮，而相較於 下方區域在上方區域内增多每單位高度之蓄水量。 (3) 於實施例1及2中，雖然使用開閉閥作為延遲裝置， 但亦可如圖13(A)、（B)所示，將延遲裝置設置於第2水箱 51。即，圖13(A)所示之第2水箱51係藉由形成有孔口 53 之分隔壁52將内部分隔成上部蓄水室51U與下部蓄水室 51D。此第2水箱51於開始進行便器洗淨當第2水箱η内 之洗淨水自下部開口 51A流出至第丨水箱21内時於便器 洗淨初期’使洗淨水通過孔口 53。此時，洗淨水由於流動 阻力相對較大，因此，第2水箱51内之水位會緩慢下=。 當第2水箱51内之水位下降至較分隔壁52下方時，由於流 動阻力小於洗淨水之空氣會通過孔口 53，因此第2水箱51 内之水位會急遽地下降。如此，藉由此一構造可形成於^交開 始進行便器洗淨慢之時機使自便器排水路侧流向第2水箱 51側之氣體流量成為最大之延遲敦置。 又，圖13(B)所示之第2水箱51係藉由形成有孔口幻之 101103989 32 201237238 分隔壁52將内部分隔成上部蓄水室Mu與下部蓄水室 51D ’並將比重小於洗淨水且可封閉孔口 53之球狀之浮體 54收納於下。p蓄水室51D。由於此第2水箱5ι係於開始進 行便器洗淨且第2水箱51内之洗淨水自下部開口 51A流出 至第1 jc相1内時，於便器洗淨初期，使通過孔口 μ之洗 淨水受到浮體54之阻力，因此，與沒有浮體M之情形時相 第^相$ 1内之水位會更緩慢地下降。當第2水箱51 内之水位下降至較分隔壁52τ方時，由於浮體54就會下降 而使孔口 53開放，使流動阻力小於洗淨水之空氣通過孔口 53 ’因此’第2水箱51内之水位會急遽下降。如此，藉由 此-構造可形成於較開始進行便器洗淨慢之時機使自便器 排水路侧流向第2水箱51側之氣體流量成為最大之延遲裝 置。 、 (4)於實施例2中’雖然便器洗淨裝置具備有第3水箱， 且具備具有朝向第3水箱之流出口喷出洗淨水之喷射喷嘴 之喷射泵，但如圖14所示，便器洗淨裝置6〇亦可不具備第 3水箱。於此情形時，使分支供水路37延長至第丨水箱μ 之底壁部31Β之附近為止，且將噴出嘴61之噴出口 61八配 置於底壁部31Β之附近，將供水路62之上游端開口 62α配 置於與此喷出口 61Α對向之位置並形成喷射泵即可。 接著，對第3發明之較佳實施形態進行說明。 第3發明之洗淨水控制裝置可具有設置於上述供水路之 101103989 33 201237238 泵。於此情形時，即便第1水箱之高度較低，亦可穩定地扣 制自第1水箱朝向便斗部之洗淨水之供給。 於第3發明中，可具備有控制上述第2水箱自上述便器排 水路抽吸氣體之吸氣動作之吸氣控制裝置。於此情形時，因 為藉由吸氣控制裝置可控制第2水箱自便器排水路抽吸氣 體之吸氣動作，因此，可配合自第丨水箱朝向便斗部之洗淨 水之供給狀態，於較佳之時機自便器排水路抽吸氣體，而在 便器排水路内產生虹吸作用。因此，此便器洗淨裝置可利用 虹吸作用良好地進行便器洗淨。 第3發明之吸氣控制裝置可構成為利用具有孔口（〇dfice) 之分隔壁將上述第2水箱分隔成上部蓄水室與下部蓄水 至於此凊形時，若開始自第1水箱對便斗部供給洗淨水， 、』。、初期階段使洗淨水通過孔口。由於洗淨水為液體， 因為其流動阻力會使第2水箱内之水位下降相對地變慢, 且，當第2水箱内之水位下降至較分隔壁下方時，流動怔 ;爭水之氣體就會通過孔口。如此一來，第2水箱产 夕 降會變快，自便器排水路所抽吸氣體之流量就售 :可使第2 7jc箱自便II排水路_ σ氣抽吸氣體， :更器排水路内產生虹吸作用。 〇 逑下部蓄水室内設置可藉由漂浮於洗淨水而詞 上述孔口之& 斗部供妗$閉構件。於此情形時，若開始自第1水箱詞 供給洗淨水，則於其初期階段中，由於阻塞構件會網 101103989 34 201237238 口阻塞，因此，與沒有阻塞構件之情形相比，通過孔口之洗 淨水之流量會縮減。而且，於第2水箱内之水位下降而使阻 塞構件開始下降後，流動阻力小於洗淨水之氣體將會通過孔 口。如此一來，第2水箱内水位之下降會變快。由於與未設 '置阻塞構件之情形相比，可延遲自便器排水路所抽吸氣體之 • 流量變多之時機，因此可延遲在便器排水路内產生虹吸作用 之時刻。 接著，一面參照圖式，一面說明使具備有第3發明之便器 洗淨裝置之水洗式便器具體化之實施例3〜6。 <實施例3> 又益丹侑有便器本體10 ”便器洗淨裝置3GG。便ϋ本體1G具有便斗 於便斗部U下游侧之便器排水路 上表面之,緣㈣成之唇面(Hm)通水路14。 化者 12係上游端連通於便斗部u之下端部。便° ^水路 自頂部(最高之部分)至便斗部 7路12係 水封部13。便器排水路m ^為止之區域成為 使器排水路】2係位於較水封部】 巧 之位置且具有朝較水封部13上方開口 近下游側 器排水路U係於自通氣口 乳口匕又，便 尺寸縮小之縮減部i6。下方延伸之區域具有將直捏 2 更。。洗淨裝置300具備有第} 水箱〗IS *s々a 相！】〇、供水路Ih 15、通祕 W、第 丨0_989 及吸氣控制Embodiments 1 and 2, for example, the following embodiments are also included in the technical scope of the present invention. K (1) In the first and second embodiments, the upper portion of the outer casing portion is housed in the second water tank that is expanded in the horizontal direction and is fixed in the second water tank. In the lower area, the water storage capacity per unit height is reduced in the upper area. However, as shown in Fig. 12 (A) and (8), the 44th portion does not deform the outer casing portion in the up and down direction, and the i-th water tank * 7 parts The amount of water stored per unit height in the upper region is recessed toward the inside by 'by'. X, as shown in Fig. 12 (Q, above the inner side of ^101103989 201237238 钿43, installing different parts of the rectangular parallelepiped for reducing the water storage amount per unit height in the upper region compared to the lower region (2) In the second and second embodiments, the second water tank is such that the upper portion of the outer casing portion is enlarged in the horizontal direction from the lower portion, but as shown in Fig. 12 (the second water tank 45 is also shown The upper portion of the outer casing portion is enlarged in a plurality of directions such as the horizontal direction in the horizontal direction, and the second water tank 46 is gradually contracted toward the inner side by the outer casing portion as shown in Fig. 12(E). The amount of water stored per unit height is increased in the upper region compared to the lower region. (3) In the first and second embodiments, although the opening and closing valve is used as the delay device, it may be as shown in Figs. 13(A) and (B). As shown in the figure, the delay device is disposed in the second water tank 51. That is, the second water tank 51 shown in Fig. 13(A) is partitioned into the upper water storage chamber 51U by the partition wall 52 having the opening 53 formed therein. The lower water storage chamber 51D. The second water tank 51 starts to wash the toilet water, and the washing water in the second water tank η is from the bottom. When the opening 51A flows out into the third water tank 21, the washing water passes through the orifice 53 at the initial stage of the toilet washing. At this time, since the washing water has a relatively large flow resistance, the water level in the second tank 51 is slow. When the water level in the second tank 51 drops below the partition wall 52, since the air having a flow resistance smaller than the washing water passes through the orifice 53, the water level in the second tank 51 is drastically lowered. With this configuration, it is possible to form a delay at the time when the toilet is washed slowly, and the flow rate of the gas flowing toward the second tank 51 on the side of the toilet drain is maximized. Further, as shown in Fig. 13(B) The second water tank 51 is divided into an upper water storage chamber Mu and a lower water storage chamber 51D' by a partition wall 52 formed with an aperture 101103989 32 201237238, and the ball having a specific gravity smaller than the washing water and closing the orifice 53 The floating body 54 is housed in the lower p-storage chamber 51D. The second tank 5 is started to be washed in the toilet, and the washing water in the second tank 51 flows out from the lower opening 51A to the first jc phase 1 At the beginning of the washing of the toilet, the washing water passing through the orifice μ is subjected to The resistance to the floating body 54, therefore, the water level in the phase phase $1 will fall more slowly than in the case where there is no floating body M. When the water level in the second water tank 51 drops to the side of the partition wall 52τ, The floating body 54 is lowered to open the opening 53, so that the flow resistance is smaller than the air passing through the opening 53 of the washing water. Therefore, the water level in the second water tank 51 is rapidly lowered. Thus, the structure can be formed by In the second embodiment, the toilet cleaning device is provided with a third water tank in the second embodiment. Further, an injection pump having an injection nozzle that discharges the washing water toward the outlet of the third water tank is provided. However, as shown in FIG. 14, the toilet cleaning device 6 may not include the third water tank. In this case, the branch water supply path 37 is extended to the vicinity of the bottom wall portion 31A of the second water tank μ, and the discharge port 61 of the discharge nozzle 61 is disposed in the vicinity of the bottom wall portion 31Β, and the water supply path 62 is upstream. The end opening 62α may be disposed at a position opposed to the discharge port 61Α to form an injection pump. Next, a preferred embodiment of the third invention will be described. The washing water control device according to the third aspect of the invention may have a pump 101103989 33 201237238 provided in the water supply path. In this case, even if the height of the first tank is low, the supply of the washing water from the first tank toward the bowl portion can be stably buckled. According to the third aspect of the invention, the intake control device for controlling the intake operation of the second water tank to suck the gas from the toilet drain passage may be provided. In this case, since the suction control device can control the suction operation of the suction gas from the second tank self-container drainage passage, the supply state of the washing water from the third water tank toward the toilet portion can be matched. Preferably, the machine draws gas from the toilet drain and creates a siphon effect in the toilet drain. Therefore, the toilet washing device can perform the toilet washing well by the siphon action. In the air intake control device according to the third aspect of the present invention, when the second water tank is partitioned into the upper water storage chamber and the lower water storage tank by the partition wall having the opening, the first water tank pair is started. The toilet bowl supplies washing water, 』. In the initial stage, the washing water is passed through the orifice. Since the washing water is a liquid, the flow resistance of the second water tank is relatively slowed down because of the flow resistance, and when the water level in the second water tank drops below the partition wall, the water flows; Will pass through the orifice. In this way, the second tank will become faster in the evening, and the flow of the gas pumped from the toilet drain will be sold: the second 7jc tank can be used as the II draining channel _ σ gas pumping gas: A siphon effect is generated inside. 〇 The lower water storage room can be installed by floating in the washing water. In this case, if the supply of the washing water from the first tank word is started, in the initial stage, since the blocking member net 101103989 34 201237238 is blocked, the passage through the orifice is compared with the case where there is no blocking member. The flow of washing water will be reduced. Further, after the water level in the second water tank drops and the blocking member starts to fall, the gas having a flow resistance lower than that of the washing water passes through the orifice. As a result, the water level in the second tank will decrease rapidly. Since the flow rate of the gas to be sucked from the toilet drainage path can be delayed as compared with the case where the 'blocking member is not provided, the timing of siphoning in the toilet drainage path can be delayed. Next, Embodiments 3 to 6 in which the flush toilet equipped with the toilet washing device of the third invention is embodied will be described with reference to the drawings. <Example 3> Further, the toilet bowl body 10 ” toilet cleaning device 3GG. The toilet body 1G has a toilet bowl on the downstream side of the toilet bowl U on the surface of the toilet drainage surface, and the edge (4) is formed into a lip surface (Hm) The water passage 14 is connected to the lower end of the bowl portion u. The water path is from the top (the highest part) to the toilet part 7 and the 12 series water seal portion 13. The toilet drain path m ^ The area is the water drain of the actuator. The 2 series is located at the position of the water seal. The opening is closer to the upper side of the water seal part 13 and the downstream side of the drain line U is attached to the nipple of the ventilator. The reducing portion i6 has a region in which the lower portion is extended.

水洗式便器可良好地進行便器洗淨。 即’於便器本體10為便器排水路12中排水流量變多之形 狀之情形時，將泵120所加壓輸送洗淨水之流量設定為變 少，減少對便斗部11所供給洗淨水之流量即可。如此一來， 可防止穢物向通氣路118内抽吸。藉此，第2水箱115可確 實地抽吸便器排水路12内之氣體，而可確實地在便器排水 路12内產生虹吸作用。 又，於便器本體10為便器排水路12中排水流量變少之形

2水相115自便器排水路12抽吸氣體之抽吸力。藉此，可 在便器排水路12内產生強力之虹吸作用，而良好地進行便 器洗淨。而且’若於便器洗淨之末期，縣120之加壓輸送 流量設為少#’則可以最少限度之洗淨水使水封部13成為 滿水狀態。 101103989 40 201237238 <實施例4> 實施例4之水洗式便器係如圖16 鬩所不’便器洗淨裝置31〇 之吸氣控制裝置124不同於實祐彻1 " 夏她例3。其他構成係與實施例 3相同，而相同之構成係標註相固 相问之付旎，並省略詳細之說 明。 吸氣控制裝置m具有將第2水箱115内分隔成上部蓄水 室127與較上部蓄水室127下方之下部蓄水請之分隔壁 125。此分㈣125係形成有朝上下貫通之孔口 m。分隔 壁⑵係設置於較待機狀態之洗淨水之最高蓄水位低之位 置。上部蓄水冑127係於上端部開口有輯氣口117:下部 蓄水室128係於下端部開口有連通口叫。又，通氣路118 未設置通氣用電磁開閉閥。因此’在第2水箱ιΐ5内較洗淨 水上方之”、與在便料林12巾較水封部Μ 游側)之空間係於平常時相連通。 若自第1水箱110開始對便斗部11供給洗淨水，則第i 水箱110内之洗淨水將迅速地向便斗部η側流出而使蓄積 於第1水箱110中第2水箱出以外之區域之洗淨水水位迅 速下降。另-方面’於第2水箱115内，由於在供給之 (即、於縮減部16直至洗淨水形成水膜為止之期間），通過 孔口 126之洗淨水係流動阻力相對較大之洗淨水(液體），因 此，第2水相^上部蓄水室127)内之水位下降相對較慢。 因此，第2水箱115自便器排水路12内抽吸之氣體之流量 101103989 201237238 較少。吸氣控制裝置124係設計為於縮減部16形成洗淨水 之水膜之時機，使第2水箱115内之水位下降至較分隔壁 125下方。若第2水箱115内之水位下降至較分隔壁125下 方’則流動阻力小於洗淨水之氣體將通過孔口 126。因此， 第2水箱115(下部蓄水室128)内水位之下降會變快。即， 由於第2水箱115自便器排水路12内所抽吸氣體之流量變 多’而可一 口氣抽吸便器排水路12内之氣體，因此，可在 便器排水路12内產生虹吸作用。 再者，若使第2水箱115内水位之下降較第丨水箱11()内 水位之下降慢，則於第1水箱110内之水位下降，自第i 水箱110内所流出洗淨水之流量變少時，存在自第2水箱 H5内向第丨水箱11〇内流入之洗淨水之流量多於自第工水 箱110内流出之洗淨水之流量的情況。如此一來由於第1 水相110内與第2 7jc箱115内之水位差變小，因此第2水箱 115内水位之下降速度會變慢，第2水箱115之抽吸力會下 降。藉此’存在有氣體自第2水箱115向便器排水路⑴則 逆流而導致虹吸作用結束之虞。 然而’此水洗式便器可藉由栗12〇增加自第1水箱n 内流出至便斗部11側之洗淨水之流量。因此，可避免第 水箱U0内與第2水箱115内之水位差變小而使第冰 115内水位之下降速度變快。藉此，可防·止第2水箱115: 抽吸力下降，而使虹吸作用持續。 101103989 42 201237238 又’為了使第2水箱115内初期水位之下降變慢，使開始 便器洗淨後直至第2水箱115自便器排水路12内所抽吸之 氣體流量增多為止之時間延遲，可將孔口 126之内徑縮小。 然而，若縮小孔口 126之内徑，則存在有洗淨水内之異物使 孔口 126堵塞之虞。就此而言，由於此水洗式便器係藉由泵 120將上部蓄水室127内之洗淨水強制地抽吸至下部蓄水室 128側，因此’於孔口 126不會有發生堵塞之虞。 <實施例5> 實施例5之水洗式便器係如圖17所示，便器洗淨裝置320 之吸氣控制裝置129不同於實施例4。其他構成與實施例4 相同，且相同之構成係標註相同之符號，並省略詳細之說明。 吸氣控制裝置129係於第2水箱115之下部蓄水室128 内收容有可阻塞孔口 126之阻塞構件13〇。此阻塞構件130 係比重小於洗淨水。因此，封閉構件130係漂浮於第2水箱 115内之洗淨水。因此，若第2水箱115内洗淨水之水位為 既定高度以上’則阻塞構件130會利用浮力而自下侧阻塞孔 口 126。 若自第1水箱110開始對便斗部11供給洗淨水，則於供 給之初期’阻塞構件130將利用浮力而自下側阻塞孔口 126。因此，與沒有阻塞構件130之情形相比，通過孔口 126 之洗淨水之流量會被縮減。通過此時之孔口 126之流量受到 作用於阻塞構件130之浮力之影響，並且因第2水箱115 101103989 43 201237238 内與第1水箱lio内洗淨水之水位差而變動。 而且，若第2水箱115内洗淨水之水位低於分隔壁125 之下表面，則流動阻力小於洗淨水之空氣將通過孔口 126。 因此，第2水箱115内水位之下降會變快，可在便器排水路 12内產生虹吸作用。此水洗式便器係於洗淨水通過孔〇 126 之期間，藉由阻塞構件130而使孔口 126之開度變窄，因此， 與未設置阻塞構件130者相比’可延遲在便器排水路12内 產生虹吸作用之時機。又，因為於氣體開始通過孔口 126 之前’若減少泵120所加壓輸送洗淨水之流量，則第1水箱 110内與第2水箱115内之水位差會變小，因此，通過孔口 126之洗淨水之流量會減少’亦可延遲便器排水路12内虹 吸作用之產生。 <實施例6> 實施例6之水洗式便器係如圖18所示，便器洗淨裝置33〇 之洗淨水控制裝置131不同於實施例3。其他構成係與實施 例3相同，且相同之構成係標註相同之符號，並省略詳細之 說明。 水洗式便器係將第1水箱no設置於較便斗部η高之位 置。因此，第1水箱110内及第2水箱115内洗淨水之最高 蓄水位係成為充分高於便斗部11之位置。便器洗淨裝置33〇 係於供水路114之中途具有供水用電磁開閉閥ι21、及配置 於較供水用電磁開閉閥121靠下游側（便斗部u侧）之供水 101103989 44 201237238

便ϋ洗淨裝置配置於較便器本體之上表面低之位置，藉由噴 射泵，亦可將大流量之洗淨水供給至便器本體。因此，可藉 由具備便器本體、與此便器洗淨裝置而實現低輪廓之水洗式 便器。 第4發明之喷嘴可噴射洗淨水直至空氣自上述第丨水箱經 由上述流入口流入至上述第3水箱内，使上述第3水箱内之 水位下降為止’此情形時，若空氣自第丨水箱經由流入口 «入至第3水粕内，則第3水箱内之水位就會急遽下降，喷 將》’、’έ·及5丨第3 7]c箱内之洗淨水’而使來自喷嘴之洗淨 水之噴射停止。於洗淨水對噴嘴之之供水壓力變動之情形 寺由於噴射之洗淨水之流量發生變動，因此，吸引至喷射 泵之第3水勒内洗淨水之流量亦會發生變動。如此，若洗淨 脅紫之供水壓力發生變動’則供給至便器本體之洗淨水 μ里就會發生變動，但此便器洗淨裝置可使供給至便器本 i〇1J03989 47 201237238 體之洗淨水之水量大致為一定。 即，直至第3水箱内之水位下降為止，吸引至喷射泵之洗 淨水之水量係與蓄積於第3水箱之外側即第1水箱内之洗淨 水之水量同等，且大致為一定。於喷射泵吸引一定水量之洗 淨水時，若自喷嘴所喷射洗淨水之流量較少，則喷出時間會 變長，若自喷嘴所喷射洗淨水之流量較多，則喷出時間會變 短。如此，為使喷射录吸引一定水量之洗淨水，而喷出自喷 嘴所喷射洗淨水之水量亦喷出大致一定之水量。因此，自喷 嘴所喷射洗淨水之流量發生變動，被吸引之第3水箱内洗淨 水之流量發生變動，藉此即便使供給至便器本體之洗淨水之 流量發生變動，此便器洗淨裝置亦可使供給至便器本體之洗 淨水之水量大致為一定。 於第4發明中，可變更空氣開始自上述第1水箱經由上述 流入口流入至上述第3水箱時之上述第1水箱内之水位。於 此情形時，可藉由變更空氣開始自第1水箱經由流入口流入 至第3水箱時第1水箱内之水位，而變更供給至便器本體之 洗淨水之水量。即，若使空氣開始自第1水箱經由流入口流 入至第3水箱時第1水箱内之水位變低，則第3水箱内洗淨 水之水位之下降時期會變慢，喷射泵可長時間吸引第3水箱 内之洗淨水。因此，便器洗淨裝置可使供給至便器本體之洗 淨水之水量變多。另一方面，若使空氣開始自第1水箱經由 流入口流入至第3水箱時之第1水箱内之水位變高，則第3 101103989 48 201237238 水箱内之洗淨水水位之下降時期會變早，噴射 引第3水箱内之洗淨水。因此，便器洗淨裝置^法早期吸 器本體之洗淨权水量變少。如此，此便器洗彳―至便 地變更供給至便器本體之洗淨水之水量，故可/置可容易 器洗淨水衫同之減麵之便料體。W地對應便 …發明中’可具備連通上述㈣箱之下 嘴之連祕、及設置於此連通路且將蓄積於上 二、 之洗淨水輸送至上射嘴之輸水裝置。於此情，水相内

便器本體10具有便斗部11、及連通於便斗部11下游側之 便器排水路12。 便器洗淨裝置220係配置於便器本體10之後方，且較便 器本體10之上表面低之位置。因此，此水洗式便器係實現 低輪廓。此便器洗淨裝置22〇具備有第1水箱221、第2水 101103989 49 201237238 箱222、喷射泵223及供水路224。第丨水箱221係經由連 通於作為供水源之水道管之水箱供水路225而流入洗淨 水。水鈿供水路225具有設置於下游端之水箱供水用閥 225V。第1水箱221可蓄積經由水箱供水路225所流入之 洗淨水。 第2水箱222係配置於第}水箱221内。此第2水箱222 具有於第1 7jc箱221内之下部附近朝向下方開放之流入口 222A。又’此第2水箱222係於上端部具有流出口 222B。 第2水箱222係自上表面水密狀地***有對下述喷射噴嘴 226供給洗淨水之分支供水路227。流出口 222B之開口面 積係形成為大於喷射喷嘴226之喷射口 226A之開口面積。 供水路224係連通流出口 222B與便器本體1〇。此供水路 224係自流出口 222B之開口緣連續地延伸。因此，供水路 224之流路面積係形成為大於喷射噴嘴226之喷射口 226A 之開口面積。又，供水路224係直至到達便器本體1〇之後 端上部為止，具有朝向斜上方之上升斜率，且以使下游端之 喷水口 224A沿著便器本體1〇之便斗部u之上部周緣喷出 洗淨水之方式配置。因此，自供水路224之喷水口 224A所 喷出之洗淨水可沿著便斗部11之表面朝一方向流動，而於 便斗部11内形成旋流。 又，由於第2水箱222之流出口 222B形成於第2水箱222 之上端部，故供水路224不會變長，又，供水路224之上升 101103989 50 201237238 斜率不會變陡。因此，可減少通過供水路224之洗淨水之壓 力才貝失。 喷射泵223具有於第2水箱222内且配置於與第2水箱 222之流出口 222B隔著間隙相對向之位置之喷射嗔嘴 226。噴射泵223係由第2水箱之流出口 222B與噴射噴嘴 226所構成。此喷射喷嘴226係設置於第2水箱222内之上 部’以使洗淨水之喷出方向朝向流出口 222B之方式使噴出 之洗淨水沿著供水路224流動。如此，喷射泵223係配置於 第2水箱222之上部。喷射噴嘴226係經由將水箱供水路 225分支之分支供水路227流入有洗淨水。分支供水路227 具有喷射噴嘴用閥227V。 接著，對具有上述構成之水洗式便器之便器洗淨步驟進行 說明。 便器洗淨前之待機狀態’如圖19所示，自水箱供水路225 所流入之洗淨水係流入第1水箱221内。而且，洗淨水自第 1水箱221之下部經由第2水箱222之流入〇 222A亦流入 第2水箱222内。即，水洗式便器係於第i水箱22ι及第2 水箱222中將洗淨水蓄積至滿水狀態而成為便器洗淨前之 待機狀態。於此待機狀態下水箱供水用閥225v及喷射S嘴 用閥227V為閉閥狀態。 ' 又，於便器洗淨前之待機狀態下，由於與朝第丨水# 上方開口之開口面積相比，供水路224之下游端之開=積 101103989 51 201237238 較小，因此，因為第1水箱221内洗淨水之水壓，使得洗淨 水自第2水箱222流入連通於下游側之供水路224内為止。 即，第2水箱222係藉由洗淨水而成為滿水狀態，且在供水 路224内洗淨水之水位上升至高於第2水箱222外側之第1 水箱221内之洗淨水之水位之位置為止。 接著’當開始進行便器洗淨時’如圖2〇所示，喷射喷嘴 用閥227V就會開閥。如此一來，洗淨水就會自喷射喷嘴226 之喷射口 226A喷射，並吸引第2水箱222内之洗淨水。自 喷射噴嘴226之喷射口 226A所噴射之洗淨水、與被上述喷 射所吸引之第2水箱222内之洗淨水合流後，經由供水路 224將洗淨水供給至便器本體。此時，可將自喷射噴嘴 226之喷射口 226A所喷出洗淨水之流量之約3〜4倍流量之 洗淨水供給至便器本體10。 由於此便器洗淨裝置220係將噴射泵223配置於第2水箱 222之上部，故供水路224未變長，又，供水路224之上升 斜率未變陡。因此，可減少通過供水路224之洗淨水之壓力 損失。因此，此便器洗淨裝置22〇可將大流量之洗淨水供給 至便器本體10。 在藉由喷射泵223 ’吸引第2水箱222内之洗淨水，而開 始將大流量之洗淨水供給至便器本體1〇之同時，使第丨水 相221下部之洗淨水經由第2水箱222之流入口 222A流入 第2水箱222内。藉此，使第丨水箱221内洗淨水之水位下 101103989 52 201237238 降。此時’第2水箱222内之洗淨水係受到第1水箱221 内洗淨水水壓的影響，由洗淨水將第2水箱222内維持為滿 水狀態。因此，喷射果223可維持為沈沒於第2水箱222 内之洗淨水中之狀態。因此，喷射泵223可持續地吸引第2 水箱222内之洗淨水，並可將大流量之洗淨水持續供給至便 器本體10。 若進一步持續進行便器洗淨，則如圖21所示，第丨水箱 221内洗淨水之水位會進一步下降，且第1水箱221内洗淨 水之水位會比第2水箱222之流入口 222A更為下降。如此 一來’空氣自第i水箱221經由第2水箱222之流入口 222A 流入第2水箱222内，使第2水箱222内洗淨水之水位一口 氣下降。因此’喷射泵223就會露出於第2水箱222内，而 使喷射泵223無法吸引洗淨水。 便器洗淨裝置220具有偵測第2水箱222内之水位之未圖 示之水位感測器（例如浮球感測器），且當此水位感測器偵測 到第2水相222内之水位下降時’就會將喷射喷嘴用閥227V 閉閥。如此，結束對便器本體10之洗淨水之供給。即，喷 射噴嘴226將會喷射洗淨水，直至空氣自第丨水箱221經由 々丨l入口 222A流入第2水箱222内，而使第2水箱222内之 水位下降為止》

The first tank is stored in the washing water supplied from the floating hydrant 111 having the water supply valve i12. The toilet washing device 3 supplies the washing water stored in the first tank 110 to the water tank of the toilet bowl portion H) and has a drain port 113 formed at the lower end portion. The drain port is connected to the upstream end of the water supply road η#. The water supply path U4 connects the downstream end to the lip surface water passage 〖4. The washing 7jc accumulated in the $1 water tank 110 can be supplied to the ternary water passage 14 via the water supply path H4. ° The second aqueous phase 115 is formed into a cylindrical shape in which the upper end is blocked and the lower surface is opened as the communication port U6. The second water tank 115 is fixed within the first water object U0. p. The second tank 115 is a communication port 116 in the j-th tank HQ* which is located at a height = opening below the highest water storage level of the washing water stored before the toilet is washed. The internal space of the second tank 115 (the space in which the washing water is accumulated) is the connection port m and the first! The internal space of the water tank 110 (between * of the accumulated washing water) is connected. The second tank has a suction and discharge port 117 which is formed at the upper end portion and which is opened at a position higher than the highest water storage level of the washing water in the m:m. The air intake and exhaust port 117 is connected to the air passage 118; the palpit. Ventilation 1 118 connects the other end to the vent 15 of the toilet drain 12'Z. gP, the air passage 118 is connected to the position of the oldest water storage level of the first water tank 110 in the second water tank il5, and the private drain water passage 12 is privately placed. 4 U is higher than the water seal portion 13 The washing water control device 119 has a water supply passage 120 and a water supply electromagnetic opening and closing valve 121. & 1 μ 114 The pump is pumped to the side of the toilet bowl 11 (lip surface water passage 14) by pressurizing the washing water accumulated in the tank 110103989 36 201237238. The pump 120 has a flow rate adjustment function that can increase or decrease the flow rate of the washing water to be pressurized and regulated without being restricted by the head pressure of the first tank 110. That is, the flow rate of the washing water supplied from the first tank 110 to the side of the bowl portion 11 may be smaller than the flow rate determined only by the head pressure of the first tank 110, or may be larger than the head pressure of the first tank 110 alone. flow. When the water supply electromagnetic opening and closing valve 121 is opened, the state in which the washing water is supplied from the first tank 110 to the side of the toilet portion 11 is allowed. When the water supply electromagnetic opening and closing valve 121 is closed, the first water tank 110 is closed. The supply of the washing water to the side of the bowl portion 11 is stopped. The intake control device 122 has a ventilation electromagnetic opening and closing valve 123 provided in the middle of the air passage 118. When the ventilation electromagnetic opening and closing valve 123 is opened, the space on the downstream side (upper side) of the water seal portion π in the toilet drainage channel 12 is connected to the space above the washing water in the second water tank 115. It becomes a state in which air can flow between the two spaces. Further, when the ventilation electromagnetic opening and closing valve 123 is closed, the flow of air in the air passage 118 is blocked. Next, the toilet washing step of the flush toilet having the above configuration will be described. In the standby state before the toilet is washed, the water supply toilet valve 121 is in a closed state, and the pump 12 is stopped. The first water μ system accumulates the washing water until the highest water level. The second tank water accumulates to the water (four) of the first tank (4). Another - square 5 first net body consumption will be washed water storage material 13 (four) into a water seal. , the toilet water supply electromagnetic opening and closing valve 121 is switched to the open state. 'At the same time the pump 120 is started. In this case, the supply of the washing water from the first tank u to the bowl portion m (i.e., the cleaning) is started. The washing water that is pressurized and transported from the first tank 110 to the side of the bowl portion 11 is supplied to the bowl portion u through the lip surface water passage 14, and the waste in the bowl 4 11 is flushed toward the bowl II drain. 12 sides. Further, the washing water in the toilet bowl draining passage 12 is scattered in the reducing portion 16 to form a water film. In addition, when the washing water in the first tank 110 starts flowing out to the side of the toilet portion 11, the air-operating electromagnetic opening/closing valve 123 is switched from the closed valve state to the valve-opening state after the washing water starts to flow out to the toilet portion U. . When the ventilation electromagnetic opening/closing is opened, the space above the washing water in the second tank is connected to the space above the water seal portion 13 (downstream side) in the toilet drain passage 12. Therefore, the water level of the washing water in the second tank 115 is lowered, and the gas in the upper reading water passage 12 that is lower than the water seal portion 13 is sucked into the second tank ΐ5 through the air passage 118. Thereby, the rainbow seven-way toilet body is discharged outside the toilet drainage path 12. In addition, when the washing water of the woman in the water seal portion 13 is supplied to the toilet bowl portion 1, the water supply electromagnetic opening and closing valve (2) is aged, and the pump 12G is stopped, and the washing water of the toilet portion U is sucked. When the supply of the first water tank 110 is supplied to the first water tank 110, the water supply to the first water tank 110 is supplied from the water tank η 101101989 38 201237238. . Therefore, the water level of the first water tank 11 and the second water tank 115 (1) will be cleaned up and then, when the water level is reached, the water supply from the float water plug U1 will stop, the first water tank ιι〇 and 2 The water tank 115 is expected to be at the highest water level. Thereby, the flush toilet is restored to the standby state before the toilet is washed, the bear. The toilet washing device 300 is provided with a pump 12A on the water supply path 114 as a washing water control device 119 that controls the flow rate of the washing water supplied from the first tank 110 to the toilet portion U. Therefore, the flow rate of the washing water to be pumped by the pump 120 can be controlled according to the shape of the toilet portion n and the toilet drainage path 12, and the flow rate of the washing water supplied from the first tank 110 to the toilet portion u can be appropriately set. Thereby, the flush toilet can perform the toilet washing well. In other words, when the toilet body 10 is in a shape in which the drainage flow rate in the toilet drainage channel 12 is increased, the flow rate of the pumping water to be pumped by the pump 120 is set to be small, and the washing water supplied to the toilet portion 11 is reduced. The flow can be. In this way, the waste can be prevented from being sucked into the air passage 118. Thereby, the second water tank 115 can surely suck the gas in the toilet drainage path 12, and can surely generate a siphon action in the toilet drainage path 12. When the toilet body 10 is in the shape in which the drainage flow rate in the toilet drainage channel 12 is reduced, the flow rate of the pumping water to be pumped by the pump 120 is set to be large, and the washing water supplied to the toilet part 11 is supplied. The flow rate can be increased. In this way, a siphon action can be surely generated in the toilet drainage path 12. Therefore, the flush toilet can utilize the siphon action to discharge the waste and the like to the outside of the toilet body 101103989 39 201237238 10 . Further, since the position of the first tank 110 of the flush toilet is substantially the same height as that of the bowl portion 11, the water supply pressure of the washing water cannot be increased by the head pressure of the first tank 11. However, if the flow rate of the pump 120 is set to be large, the supply of the washing water from the first tank ι10 to the bowl η can be stably performed even if the height of the first tank 1丨0 is low. Further, the flush toilet is provided with a ventilation electromagnetic opening and closing valve 123' as the intake control device 122 for controlling the intake operation of the toilet drain passage 12 toward the second tank 115. When the switch of the electromagnetic electromagnetic on-off valve (the intake operation of the toilet drain passage 12 toward the second tank 115) is controlled by the switch of the water supply electromagnetic opening and closing valve 121 and the pump 120, the second tank 115 can be fitted. The supply state of the first water tank 1 toward the washing water of the toilet bowl 11 is preferably sucked by the toilet drain passage 12 at a desired timing to generate a siphon action in the toilet drain passage 12. For example, in the initial stage, the flow rate of the pumping water to be pumped by the pump 12 is set to a small amount, and the toilet bowl 11 is washed, and the water film of the washing water is formed in the reducing portion 16. Thereafter, the flow rate of the pumping water supplied by the pump 12 增加 is increased, and the suction force of the second water phase 115 to suck the gas from the toilet drain path 12 is enhanced. Thereby, a strong siphon action can be generated in the toilet drainage path 12, and the toilet can be washed well. Further, if the pressurized transport flow rate of the county 120 is set to be less than the end of the toilet washing, the water seal portion 13 can be made full of water with a minimum of washing water. 101103989 40 201237238 <Example 4> The water-washing toilet of the embodiment 4 is the same as the suction control device 124 of the toilet cleaning device 31 of the present invention. The other components are the same as those of the third embodiment, and the same components are denoted by the same reference numerals, and detailed descriptions thereof will be omitted. The intake control device m has a partition wall 125 that partitions the inside of the second tank 115 into the upper water storage chamber 127 and the lower portion of the lower water storage chamber 127. This sub-fourth (125) 125 system is formed with an opening m that penetrates upward and downward. The partition wall (2) is disposed at a position lower than the highest water storage level of the washing water in the standby state. The upper water storage port 127 is provided with a gas collecting port 117 at the upper end opening: the lower water storage chamber 128 is connected to the lower end portion with a communication port. Further, the air passage 118 is not provided with an electromagnetic opening/closing valve for ventilation. Therefore, the space in the "second water tank ιΐ5 is higher than the washing water" and the space in the toilet soil 12 to the side of the water seal portion is normally connected. If the first water tank 110 starts to the toilet When the washing water is supplied to the portion 11 , the washing water in the i-th tank 110 is quickly discharged to the side of the toilet portion η, and the water level of the washing water accumulated in the region other than the second tank in the first tank 110 is rapidly lowered. In the second tank 115, the flow resistance of the washing water passing through the orifice 126 is relatively large due to the supply (that is, during the period from the reduction portion 16 until the water film is formed by the washing water). The water (liquid) is washed, so that the water level in the second water phase upper reservoir 127) is relatively slow. Therefore, the flow rate of the gas sucked from the toilet drain 12 in the second tank 115 is 101103989 201237238 The air intake control device 124 is designed to reduce the water level in the second water tank 115 below the partition wall 125 when the water reducing film of the washing water is formed in the reducing portion 16. If the water level in the second water tank 115 drops to Below the partition wall 125, the gas having a lower flow resistance than the washing water will pass through the orifice 126. Therefore, the water level in the second tank 115 (the lower water storage chamber 128) is lowered. That is, since the flow rate of the gas sucked from the toilet drain 12 in the second tank 115 is increased, the toilet can be sucked in one breath. The gas in the drain passage 12 can cause a siphon action in the toilet drain passage 12. Further, if the water level in the second tank 115 is lowered more slowly than the water level in the second tank 11 (), the first When the water level in the water tank 110 is lowered, the flow rate of the washing water flowing from the second water tank H5 into the first water tank 11 is more than that from the water tank. In the case of the flow rate of the washing water flowing out of the first water tank 110, the water level in the first water tank 110 and the second water tank 115 are reduced, so that the water level in the second water tank 115 is slowed down. 2 The suction force of the water tank 115 is lowered. By this, there is a gas flowing back from the second water tank 115 to the toilet drainage path (1), which causes the siphon action to end. However, the water-washing toilet can be increased by the chestnut 12〇. The flow rate of the washing water flowing out to the side of the bowl portion 11 in the first tank n is therefore It is possible to prevent the water level difference between the inside of the first water tank U0 and the second water tank 115 from becoming smaller, and to increase the speed of the water level in the first ice 115. This prevents the second water tank 115 from being lowered, and the suction force is reduced. 101103989 42 201237238 Further, in order to slow down the initial water level in the second tank 115, the time until the second tank 115 is purged from the toilet drain 12 is increased after the washing of the toilet is started. The inner diameter of the orifice 126 can be reduced. However, if the inner diameter of the orifice 126 is reduced, there is a flaw in the foreign matter in the washing water to block the orifice 126. In this regard, since the flush toilet forcibly sucks the washing water in the upper water storage chamber 127 to the lower water storage chamber 128 side by the pump 120, there is no clogging in the orifice 126. . <Embodiment 5> The flushing toilet of the embodiment 5 is different from the fourth embodiment in that the inhalation control device 129 of the toilet washing device 320 is different from that of the fourth embodiment. The other configurations are the same as those in the fourth embodiment, and the same components are denoted by the same reference numerals, and the detailed description is omitted. The air intake control device 129 is housed in the lower water storage chamber 128 of the second water tank 115 and houses the blocking member 13A which can block the opening 126. The blocking member 130 has a specific gravity smaller than that of the washing water. Therefore, the closing member 130 is the washing water floating in the second tank 115. Therefore, if the water level of the washing water in the second tank 115 is equal to or higher than the predetermined height, the blocking member 130 blocks the orifice 126 from the lower side by buoyancy. When the washing water is supplied to the toilet bowl 11 from the first tank 110, the blocking member 130 will block the orifice 126 from the lower side by buoyancy at the initial stage of supply. Therefore, the flow rate of the washing water passing through the orifice 126 is reduced as compared with the case where the blocking member 130 is not provided. The flow rate through the orifice 126 at this time is affected by the buoyancy acting on the blocking member 130, and varies due to the difference in water level between the second tank 115 101103989 43 201237238 and the washing water in the first tank lio. Further, if the water level of the washing water in the second tank 115 is lower than the lower surface of the partition wall 125, the air having a flow resistance smaller than the washing water will pass through the orifice 126. Therefore, the water level in the second water tank 115 is lowered, and a siphon action can be generated in the toilet drainage path 12. The flush toilet is closed during the passage of the washing water through the bore 126, and the opening of the orifice 126 is narrowed by the blocking member 130. Therefore, the toilet drain can be delayed compared to the case where the blocking member 130 is not provided. The timing of the siphon effect in 12 is generated. Further, since the flow rate of the washing water is increased by the pump 120 before the gas starts to pass through the orifice 126, the water level difference between the inside of the first tank 110 and the second tank 115 becomes small, and therefore, the orifice is passed through the orifice. The flow of 126 wash water will be reduced, and the siphon effect in the toilet drain 12 can also be delayed. <Example 6> The flushing toilet of the embodiment 6 is different from the third embodiment in the washing water control device 131 of the toilet washing device 33A as shown in Fig. 18 . The other components are the same as those in the third embodiment, and the same components are denoted by the same reference numerals, and the detailed description is omitted. In the flush toilet, the first tank no is placed at a position higher than the hopper portion η. Therefore, the highest water storage level of the washing water in the first tank 110 and the second tank 115 is sufficiently higher than the position of the bowl portion 11. The toilet cleaning device 33 is provided with a water supply electromagnetic opening and closing valve ι21 and a water supply 101103989 placed on the downstream side of the water supply electromagnetic opening and closing valve 121 (the side of the toilet bowl u side). 132. In this manner, the first water tank m is placed at a position higher than the position of the toilet bowl 11, and the water head pressure in the first tank no is increased, and the water supply electromagnetic opening_121 and the water supply material control side 132 are installed in the water supply. The form of the road 114 constitutes a washing water control skirt (3). When the electromagnetic opening/closing valve 121 for water supply is opened, the supply of the washing water toward the toilet (4) from the first tank 1H by the head pressure of the washing water in the i-th tank is started (even if n is washed) ). The washing water in the remaining line + part u is flushed to the U side of the toilet drainage path. Further, the washing water flowing into the toilet drain passage 12 is scattered in the _ portion 16 to form a water film. Further, the disordered body in the space in which the water seal portion 13 is lower than the water seal portion 13 is sucked into the second tank 115 through the air passage 118. Thereby, the pure water drainage channel 12 shouts the siphon effect. (4) When the flow rate control valve 132 for water supply is adjusted to increase the flow rate of the washing water supplied to the toilet bowl portion u, the siphon action can be surely generated in the toilet drain passage 12, so that the stolen goods and the like can be satisfactorily Discharge to the outside of the toilet. Further, when the water supply amount flow rate control width 132 is adjusted and the flow rate of the washing water supplied to the toilet bowl portion n is reduced, it is possible to prevent the waste material from being sucked into the air passage 118. When the washing water starts to be woven to the toilet bowl portion 11, or after the washing water starts to flow out to the toilet bowl portion li, the ventilation opening/closing electromagnetic opening 123 of the L gas passage 118 is switched to the valve opening state. Therefore, the air in the toilet drain passage 12 is sucked into the second tank 115 through the air passage 118, and the siphon action is generated in the toilet drain passage 12, and the water level in the toilet drain passage 12 is lowered. The body 101103989 45 201237238 in the water seal portion η is discharged to the outside of the toilet body l. ~Γ:: No, Example 3 described by the above description and drawings is also included in the present invention. (1) Although the embodiment 3 to 6 garter, ρ 祀 祀 〒 绿 green second water; self-disposed The water tank is located, but the second tank may be disposed outside the first tank. (2) Although the third to fifth embodiments are arranged such that the position of the first water tank is equal to the door degree c of the toilet, the third water tank can be placed at a position higher than the toilet. Ο W, and Examples 3 to 5 use the effect of adjusting the flow rate of the washing water to be used as the washing water control (4), but it is also possible to use the flow control valve 2 to wash the 7JC control weaving. The washing water control device can be constituted by the pump in the washing water claw which can not be fed by the four (4) and the flow control valve which is placed on the downstream side of the pump. (3) In the third and sixth embodiments, the electromagnetic opening and closing valve for ventilation is provided as a suction control device for controlling the inhalation operation of the water tank toward the second tank, but the flow rate may be set instead of the electromagnetic opening and closing valve for ventilation. The control valve can be set to the flow control side in addition to the electromagnetic opening _ for ventilation. Further, the intake control device may not be provided. (5) In the fourth and fifth embodiments, the gas and the gas control device for controlling the suction operation of the toilet drain path toward the second water life may be provided with electromagnetic opening and closing on the air passage. , electromagnetic opening and closing valve and flow control valve can be set. (6) The inhalation control of the embodiment 4 or the embodiment 5 can also be applied to the embodiment 6. 101103989 46 201237238 (7) Although the embodiment 6 is used as the washing water control device, the first water tank is placed at the side of the toilet. In the position, the head pressure in the third tank is increased, and the electromagnetic opening and closing and the flow 1 control valve are not disposed in the water passage, but instead, the pump and the electromagnetic opening and closing valve are disposed in the water supply passage. Next, a preferred embodiment of the fourth invention will be described. The outflow port of the fourth aspect of the invention may be disposed above the third tank, and the nozzle may be disposed in the upper portion of the third tank. In this case, even if the sheet cleaning device is disposed on the toilet body At a low surface position, a large flow of washing water can be supplied to the toilet body by the jet pump. Therefore, it is possible to realize a low-profile flushing toilet by providing a toilet body and a toilet washing device. In the nozzle of the fourth aspect, the washing water can be sprayed until the air flows into the third water tank from the third water tank through the inlet port, and the water level in the third water tank is lowered. In this case, if the air is from the water tank When entering the third water level through the inflow port, the water level in the third water tank will drop sharply, and the water will be washed from the water in the '3' box. The injection of the washing water of the nozzle is stopped. In the case where the water supply pressure of the nozzle is changed by the washing water, the flow rate of the washing water to be sprayed is changed, so that the flow rate of the washing water sucked into the third water jet of the jet pump also changes. In this way, if the water supply pressure of the washed purple is changed, the washing water supplied to the toilet body may change, but the toilet washing device can be supplied to the toilet. The amount of water in the water is roughly constant. In other words, the amount of water sucked into the washing water of the jet pump is equal to the amount of water stored in the first tank, which is the outer side of the third tank, and is substantially constant until the water level in the third tank is lowered. When the jet pump draws a certain amount of washing water, if the flow rate of the washing water sprayed from the nozzle is small, the discharge time becomes long, and if the flow rate of the washing water sprayed from the nozzle is large, the discharge time is Will be shorter. In this way, in order to attract a certain amount of water to the jet recording, the amount of water ejected from the nozzle to eject the washing water also ejects a substantially constant amount of water. Therefore, the flow rate of the washing water sprayed from the nozzle fluctuates, and the flow rate of the washing water in the sucked third tank changes, and the toilet is washed even if the flow rate of the washing water supplied to the toilet body is changed. The device can also make the amount of water supplied to the toilet body substantially constant. According to the fourth aspect of the invention, the water level in the first water tank when the first water tank flows into the third water tank through the inlet port can be changed. In this case, the amount of water supplied to the toilet body can be changed by changing the water level in the first tank from the first tank through the inlet to the third tank. In other words, when the air level in the first tank is lowered when the air starts to flow from the first tank through the inlet port to the third tank, the water level of the washing water in the third tank is lowered, and the jet pump can be used for a long time. Attract the washing water in the third tank. Therefore, the toilet washing device can increase the amount of water supplied to the toilet body. On the other hand, if the water level in the first tank when the air starts to flow from the first tank through the inlet to the third tank becomes higher, the period of decline of the water level in the water tank of the third 101103989 48 201237238 will become earlier. , spray the washing water in the third water tank. Therefore, the amount of washing water of the early suction body of the toilet washing device is reduced. In this way, the toilet is washed - the amount of the water supplied to the toilet body is changed to the extent that the water can be easily removed. In the case of the invention, it is possible to provide a water delivery device that communicates with the mouth of the lower (4) case and the water supply device that is disposed in the communication path and that supplies the cleaning water stored in the upper second to the upper nozzle. In this case, the water is used in the water phase to transport the washing water at the time of the mouth, so that the water can be sent to the washing water of the I water pressure. Therefore, the spray pump can strongly attract the third water, and the large-flow washing water can be stabilized via the water supply passage 114:: to the toilet body. Supply Next, with reference to Fig. g, Embodiments 7 to 1 of the water-washing toilet equipped with the cleaning device of the fourth invention will be described.实施 <Example 7> As shown in Fig. 19, the flush toilet of the seventh embodiment includes a toilet body 10 and a toilet washing device that supplies washing water to the toilet body 1 . The toilet body 10 has a toilet bowl portion 11 and a toilet drain passage 12 that communicates with the downstream side of the toilet bowl portion 11. The toilet washing device 220 is disposed behind the toilet body 10 and at a position lower than the upper surface of the toilet body 10. Therefore, this flush toilet achieves a low profile. The toilet washing device 22A includes a first tank 221, a second water 101103989 49 201237238 tank 222, an injection pump 223, and a water supply passage 224. The third tank 221 flows into the washing water via the tank water supply passage 225 which is connected to the water conduit which is the water supply source. The water supply passage 225 has a tank water supply valve 225V provided at the downstream end. The first tank 221 can accumulate the washing water flowing in through the tank water supply passage 225. The second tank 222 is disposed in the first tank 221 . The second tank 222 has an inlet 222A that opens downward in the vicinity of the lower portion of the first 7jc tank 221. Further, the second tank 222 has an outflow port 222B at the upper end portion. In the second tank 222, a branch water supply passage 227 for supplying the washing water to the injection nozzle 226 to be described later is inserted in a watertight manner from the upper surface. The opening area of the outflow port 222B is formed to be larger than the opening area of the injection port 226A of the injection nozzle 226. The water supply path 224 is connected to the outflow port 222B and the toilet body 1〇. This water supply path 224 extends continuously from the opening edge of the outflow port 222B. Therefore, the flow path area of the water supply path 224 is formed to be larger than the opening area of the injection port 226A of the injection nozzle 226. Further, the water supply path 224 has a rising slope toward the oblique upper side until reaching the upper end portion of the toilet body 1 ,, and the water jet 224A at the downstream end is sprayed along the periphery of the upper portion of the toilet portion u of the toilet body 1 The way to wash the water is configured. Therefore, the washing water sprayed from the water spout 224A of the water supply path 224 can flow in one direction along the surface of the bowl portion 11, and a swirl flow can be formed in the bowl portion 11. Further, since the outflow port 222B of the second tank 222 is formed at the upper end portion of the second tank 222, the water supply passage 224 does not become long, and the water supply passage 224 rises 101103989 50 201237238 The slope does not become steep. Therefore, the pressure of the washing water passing through the water supply path 224 can be reduced. The jet pump 223 has an injection nozzle 226 disposed in the second tank 222 and disposed at a position opposed to the outlet 222B of the second tank 222 with a gap therebetween. The jet pump 223 is composed of an outlet port 222B of the second tank and an injection nozzle 226. The spray nozzle 226 is disposed in the upper portion of the second tank 222 so that the sprayed washing water flows along the water supply passage 224 so that the discharge direction of the washing water faces the outlet port 222B. In this manner, the jet pump 223 is disposed above the second tank 222. The injection nozzle 226 flows into the washing water via the branch water supply passage 227 that branches the water tank water supply path 225. The branch water supply passage 227 has a spray nozzle valve 227V. Next, the toilet washing step of the flush toilet having the above configuration will be described. In the standby state before the toilet is washed, as shown in Fig. 19, the washing water flowing in from the water tank water supply path 225 flows into the first water tank 221. Further, the inflow of the washing water from the lower portion of the first tank 221 through the second tank 222 also flows into the second tank 222. In other words, the flush toilet is stored in the i-th water tank 22i and the second water tank 222 to store the washing water in a full water state and to be in a standby state before the toilet is washed. In this standby state, the tank water supply valve 225v and the injection S nozzle valve 227V are in a closed state. In addition, in the standby state before the toilet is washed, the opening of the downstream end of the water supply path 224 is smaller than the opening area of the opening above the Dijon water #=101103989 51 201237238, therefore, because the first tank The water pressure of the washing water in 221 is such that the washing water flows from the second tank 222 into the water supply passage 224 that communicates with the downstream side. In other words, the second tank 222 is in a full water state by the washing water, and the water level of the washing water in the water supply passage 224 rises to a level higher than the level of the washing water in the first tank 221 outside the second tank 222. Position up to now. Then, when the toilet washing is started, as shown in Fig. 2A, the injection nozzle valve 227V is opened. As a result, the washing water is sprayed from the injection port 226A of the injection nozzle 226, and the washing water in the second water tank 222 is sucked. The washing water sprayed from the injection port 226A of the injection nozzle 226 merges with the washing water in the second tank 222 sucked by the injection, and then the washing water is supplied to the toilet body via the water supply path 224. At this time, the washing water having a flow rate of about 3 to 4 times the flow rate of the washing water sprayed from the injection port 226A of the injection nozzle 226 can be supplied to the toilet body 10. Since the toilet washing device 220 disposes the jet pump 223 in the upper portion of the second tank 222, the water supply passage 224 does not become long, and the rising slope of the water supply passage 224 does not become steep. Therefore, the pressure loss of the washing water passing through the water supply path 224 can be reduced. Therefore, the toilet washing device 22 can supply a large amount of washing water to the toilet body 10. When the washing water in the second tank 222 is sucked by the jet pump 223', the large-flow washing water is supplied to the toilet body 1b, and the washing water in the lower portion of the second water phase 221 is passed through the second The inlet 222A of the water tank 222 flows into the second tank 222. Thereby, the water level of the washing water in the second water tank 221 is lowered by 101103989 52 201237238. At this time, the washing water in the second tank 222 is affected by the water pressure of the washing water in the first tank 221, and the inside of the second tank 222 is maintained in a full water state by the washing water. Therefore, the sprayed fruit 223 can be maintained in a state of being submerged in the washing water in the second tank 222. Therefore, the jet pump 223 can continuously suck the washing water in the second tank 222, and can continuously supply the large-flow washing water to the toilet body 10. If the toilet is further washed, as shown in FIG. 21, the water level of the washing water in the second tank 221 is further lowered, and the water level of the washing water in the first tank 221 is higher than the inlet 222A of the second tank 222. More down. In this way, the air flows into the second tank 222 from the i-th water tank 221 through the inlet 222A of the second tank 222, and the water level of the washing water in the second tank 222 is lowered. Therefore, the jet pump 223 is exposed in the second tank 222, so that the jet pump 223 cannot attract the washing water. The toilet washing device 220 has a water level sensor (for example, a float sensor) that detects a water level in the second water tank 222, and when the water level sensor detects the second water phase 222 When the water level drops, the injection nozzle will be closed with valve 227V. In this way, the supply of the washing water to the toilet body 10 is ended. That is, the spray nozzle 226 will spray the washing water until the air flows into the second tank 222 from the third tank 222A through the inlet 222A, and the water level in the second tank 222 is lowered. When the water supply pressure of the nozzle 226 is changed, since the flow rate of the sprayed washing water fluctuates, it is attracted to the spray 101103989.

<實施例8 > 實施例8之水洗式便器係如圖23所示，與實施例7不同 之處在於：可藉由將便器洗淨裝置230之第2水箱231之側 面231B形成為蛇腹狀，而變更空氣開始自第丨水箱221經 由流入口 231A流入第2水箱231時之第1水箱221内之水 位。其他構成係與實施例7相同，且相同之構成係標註相同 之符號，並省略詳細之說明。 此水洗式便器之便器洗淨裝置230係可藉由伸縮第2水箱 101103989 55 201237238 231之側面231B之蛇腹部分，變更空氣開始自第1水箱221 經由流入口 231A流入第2水箱231時之第1水箱221内之 水位。因此，可變更供給至便器本體10之洗淨水之水量。 即，如圖23(A)所示，伸長第2水箱231之側面231B之 蛇腹部分，將第2水箱231之流入口 231A配置於第1水箱 221之下部。藉此，可降低空氣開始自第1水箱221經由流 入口 231A流入第2水箱231時之第1水箱221内之水位。 如此一來，由於可於開始進行便器洗淨後，延遲第2水箱 231内洗淨水水位之下降時機，因此，喷射泵223可長時間 吸引第2水箱231内之洗淨水。因此，便器洗淨裝置3可使 供給至便器本體10之洗淨水之水量變多。即，可將蓄積於 第1水箱221及第2水箱231之洗淨水中，與蓄積於流入口 231A上側且於第2水箱231外側之第1水箱221内之水量 (圖23(A)所示之X部分）大致相等之水量供給至便器本體 10。 另一方面，如圖23(B)所示，使第2水箱231之側面231B 之蛇腹部分收縮，將第2水箱231之流入口 231A配置於較 高之位置。藉此，可使空氣開始自第1水箱221經由流入口 231A流入第2水箱231時之第1水箱221内之水位變高。 如此一來，由於在開始進行便器洗淨後，第2水箱231内之 洗淨水水位提前下降，因此，喷射泵223無法在早期吸引第 2水箱231内之洗淨水。因此，便器洗淨裝置230可減少供 101103989 56 201237238 給至便器本體1 〇之洗淨水之水量。即，可將蓄積於第1水 箱221及第2水箱231之洗淨水中，與蓄積於流入口 231Α 上側且於第2水箱231外側之第i水箱221内之水量（圖23(Β) 所示之Υ部分）大致相等之水量（少於將第2水箱231之側面 231Β之蛇腹部分伸長時之水量）供給至便器本體1〇。 如此，由於實施例8之水洗式便器之便器洗淨裝置23〇 可容易地變更供給至便器本體10之洗淨水之水量，因此， 可容易地對應便器洗淨時所需洗淨水水量不同之複數種類 之便器本體10。 <實施例9> 實施例9之水洗式便器係如圖24所示，與實施例7不同 不同之處在於：可更換側面之縱向尺寸不同之複數個第2 水箱241'242之便器洗淨裝置240。其他構成係與實施例7 相同，且相同之構成係標註相同之符號，並省略詳細之說明。 由於此水洗式便器之便器洗淨裝置240係可藉由更換側 面之縱向尺寸不同之第2水箱241、242，而變更空氣開始 自第1水箱221經由流入口 241Α、242Α流入第2水箱241、 242時之第1水箱221内之水位，因此，可變更供給至便器 本體10之洗淨水之水量。 即’如圖24(A)所示’藉由將側面之縱向尺寸較長之第2 水箱241安裝於第1水箱221内，而將第2水箱241之流入 口 241Α配置於第1水箱221之下部。藉此，可使空氣開始 101103989 57 201237238 自第1水箱221經由流入口 241A流入第2水箱241時之第 1水箱221内之水位變低。如此一來，由於可於開始進行便 器洗淨後，延遲第2水箱241内洗淨水水位之下降時機，因 此，喷射泵223可長時間吸引第2水箱241内之洗淨水。因 此，便器洗淨裝置240可使供給至便器本體1 〇之洗淨水之 水量變多。即，可將蓄積於第1水箱221及第2水箱241 之洗淨水中，與蓄積於流入口 241A上側且於第2水箱241 外側之第1水箱221内之水量（圖24(A)所示之X部分）大致 相等之水量供給至便器本體1〇。 另一方面，如圖24(B)所示，藉由將側面之縱向尺寸較短 之第2水箱242安裝於第1水箱221内，而將第2水箱242 之流入口 242A配置於較高之位置。藉此，可使空氣開始自 第1水箱221經由流入口 242A流入第2水箱242時之第1 水相221内之水位變尚。如此一來，由於在開始進行便器洗 淨後，會使第2水箱242内洗淨水之水位提前下降，因此， 喷射泵223無法在早期吸引第2水箱242内之洗淨水。因 此，便器洗淨裝置240可使供給至便器本體1〇之洗淨水之 水變少。即，可將蓄積於第1水箱221及第2水箱242 之洗淨水中，與蓄積於流入口 242A上側且於第2水箱242 外侧之第1水箱221内之水量（圖24(B)所示之γ部分）大致 相荨之水量（少於安裝有側面之縱向尺寸較長之第2水箱 241時之水量）供給至便器本體1〇。 101103989 58 201237238 如此’實施例9之水洗式便器之便器洗淨裝置24〇，由於 可谷易地變更供給至便器本體10之洗淨水之水量，故可容 易地對應便器洗淨時所需洗淨水之水量不同之複數個種類 之便器本體1〇。 <實施例1〇> •實施例10之水洗式便器係如圖25所示，與實施例7不同 之處在於：便器洗淨裝置250具備有連通第1水箱221之下 部與喷射噴嘴226之連通路228、及設置於此連通路228且 對喷射喷嘴226輸送蓄積於第1水箱221内之洗淨水之作為 輸水裝置之泵P。其他構成係與實施例7相同，且相同之構 成係標註相同之符號，並省略詳細之說明。 此水洗式便器係於便器洗淨步驟中，若開始進行便器洗 淨’就驅動泵P，可自噴射喷嘴226之喷射口 226A喷射蓄 積於第1水箱221之洗淨水，並吸引第2水箱222内之洗淨 水。由於利用泵P對喷射喷嘴226輸送洗淨水，故可對噴射 喷嘴226輸送穩定之高水壓之洗淨水。因此，喷射泵223 可強力地吸引第2水箱222之洗淨水，並經由供水路224 . 將大流量之洗淨水穩定地供給至便器本體10。 . 第4發明並不限定於由上述記述及圖式所說明之實施例7 〜10，例如以下之實施例亦包含於本發明之技術範圍中。 (1)雖然於實施例7〜10中，將第2水箱配置於第1水箱 内，但亦玎相鄰地配置第1水箱與第2水箱，且設置連接各 101103989

injection pump 223 also changes. Thus, if the water supply pressure of the spray nozzle 226 changes, the flow rate of the washing water supplied to the toilet body 10 is changed, but the flush toilet flushing device 220 can be supplied to the toilet body. The amount of water in the wash water of 1〇 is roughly constant. In other words, the amount of water sucked into the jet pump 223 until the water level in the second tank 222 is lowered is substantially equal to the amount of water stored in the first tank 221 which is the outer side of the second tank 222. Therefore, it is roughly certain. When the pumping water is 223 ° and the washing water of a certain amount of water is introduced, if the flow rate of the washing water sprayed from the injection port 226 of the injection nozzle 226 is small, the injection time becomes long, and if the injection port 226 of the injection nozzle 226 is opened, When the flow rate of the jet washing water is large, the discharge time becomes shorter. In this manner, in order to cause the jet pump 223 to suck the washing water in a certain amount of water, the water sprayed from the jet port 226 of the jet nozzle 226 is also sprayed to a substantially constant amount of water. Therefore, even if the flow rate of the jetted washing water from the injection port 226 of the jet 216 is changed, the flow rate of the washing water in the sucked second tank 222 is changed, thereby supplying the washing to the toilet body 10. The flow rate of the purified water may vary, and the amount of water supplied to the toilet body 1 by the toilet washing device 220 may be substantially constant. Then, as shown in FIG. 22, the tank water supply valve 225V is opened, and the washing water flows into the first tank 221 from the tank water supply passage 225, and the washing water is stored in the first tank 221 and the second tank 222. Thereby, as shown in FIG. 19, the flush toilet is returned to the standby state before the toilet is washed. Thus, the end of the 101103989 54 201237238 one step of the washing step. The flush toilet can dispose the toilet washing device 22G behind the toilet body 1 , and below the upper surface of the toilet body to achieve a low profile. Further, in the flush toilet, the water pumping passage 223 is disposed in the upper portion of the second tank 222, so that the water supply passage 224 is not elongated, and the rising slope of the water supply passage 224 is not steepened, so that the water supply passage 224 can be reduced. The pressure loss of the washing water is supplied to the toilet body 1〇 with a large flow of washing water. The toilet washing device 220 is configured to suck the washing water in the second tank 222 until most of the washing water in the first tank 221 flows into the second tank 222, so that a large flow of washing water can be used. It is supplied to the toilet body 1〇 for a long time. That is, the flush toilet can use most of the washing water stored in the first tank 221 and the second tank 222. Therefore, the flush toilet of the seventh embodiment has the degree of freedom in the position where the toilet washing device 22 is placed, and the toilet can be washed well. <Embodiment 8> The water-washing toilet of the embodiment 8 is different from the seventh embodiment in that the side surface 231B of the second tank 231 of the toilet bowl cleaning device 230 can be formed into a bellows as shown in FIG. In the shape of the water tank, the water level in the first tank 221 when the second tank 231 flows into the second tank 231 via the inlet 231A is changed. The other configurations are the same as those in the seventh embodiment, and the same components are denoted by the same reference numerals, and the detailed description is omitted. The flush toilet flushing device 230 can change the first portion of the bellows portion 231B of the second water tank 101103989 55 201237238 231 to change the first air tank 221 from the first water tank 221 to the second water tank 231 via the inflow port 231A. The water level in the water tank 221. Therefore, the amount of water supplied to the toilet body 10 can be changed. That is, as shown in Fig. 23(A), the bellows portion of the side surface 231B of the second tank 231 is extended, and the inlet 231A of the second tank 231 is disposed at the lower portion of the first tank 221 . Thereby, the water level in the first tank 221 when the air starts to flow from the first tank 221 into the second tank 231 via the inlet 231A can be reduced. In this manner, since the timing of the lowering of the washing water level in the second tank 231 can be delayed after the toilet washing is started, the jet pump 223 can suck the washing water in the second tank 231 for a long time. Therefore, the toilet washing device 3 can increase the amount of water supplied to the toilet body 10. In other words, the amount of water stored in the washing water in the first tank 221 and the second tank 231 and in the first tank 221 which is stored above the inlet 231A and outside the second tank 231 can be shown in FIG. 23(A). The X portion) is supplied to the toilet body 10 in substantially equal amounts of water. On the other hand, as shown in Fig. 23(B), the bellows portion of the side surface 231B of the second tank 231 is contracted, and the inlet 231A of the second tank 231 is placed at a higher position. Thereby, the water level in the first tank 221 when the air starts to flow from the first tank 221 into the second tank 231 via the inlet 231A can be increased. In this manner, since the water level of the washing water in the second tank 231 is lowered in advance after the washing of the toilet is started, the jet pump 223 cannot suck the washing water in the second tank 231 at an early stage. Therefore, the toilet washing device 230 can reduce the amount of water supplied to the toilet body 1 of the 101103989 56 201237238. In other words, the amount of water stored in the washing water in the first tank 221 and the second tank 231 and in the i-th tank 221 which is stored above the inlet 231 且 and outside the second tank 231 can be shown in FIG. 23 (Β). The amount of water (which is less than the amount of water when the bellows portion of the side surface 231 of the second tank 231 is extended) is supplied to the toilet body 1A. As described above, since the flush toilet flushing device 23 of the eighth embodiment can easily change the amount of the washing water supplied to the toilet body 10, the amount of washing water required for the toilet washing can be easily made different. A plurality of types of toilet bodies 10. <Embodiment 9> The flush toilet of the embodiment 9 is different from the seventh embodiment in that it is different from the seventh embodiment in that the plurality of second water tanks 241'242 having different longitudinal dimensions are replaceable. Device 240. The other configurations are the same as those in the seventh embodiment, and the same components are denoted by the same reference numerals, and the detailed description is omitted. The flush toilet flushing device 240 can change the air from the first tank 221 to the second tank 241 via the inlets 241, 242, by replacing the second tanks 241 and 242 having different longitudinal dimensions. Since the water level in the first tank 221 at 242 hours, the amount of water supplied to the toilet body 10 can be changed. That is, as shown in Fig. 24(A), the second water tank 241 having a long vertical dimension on the side surface is attached to the first water tank 221, and the inlet 241 of the second water tank 241 is disposed in the first water tank 221 Lower part. As a result, the air level in the first tank 221 when the first water tank 221 flows into the second tank 241 from the first tank 221A through the inlet port 241A can be lowered. In this manner, since the timing of the lowering of the washing water level in the second tank 241 can be delayed after the toilet washing is started, the jet pump 223 can suck the washing water in the second tank 241 for a long time. Therefore, the toilet washing device 240 can increase the amount of water supplied to the toilet body 1 to the washing water. In other words, the amount of water stored in the washing water in the first tank 221 and the second tank 241 and in the first tank 221 which is stored on the upper side of the inlet 241A and outside the second tank 241 can be shown in FIG. 24(A). The X portion) is supplied to the toilet body 1〇 with substantially equal amount of water. On the other hand, as shown in Fig. 24(B), the second tank 242 having a short vertical dimension on the side surface is attached to the first tank 221, and the inlet 242A of the second tank 242 is placed at a higher level. position. Thereby, the water level in the first water phase 221 when the air starts to flow from the first tank 221 to the second tank 242 via the inlet 242A can be changed. As a result, since the water level of the washing water in the second tank 242 is lowered in advance after the washing of the toilet is started, the jet pump 223 cannot suck the washing water in the second tank 242 at an early stage. Therefore, the toilet washing device 240 can reduce the amount of water supplied to the toilet body 1 to the washing water. In other words, the amount of water stored in the washing water in the first tank 221 and the second tank 242 and in the first tank 221 which is located above the inlet 242A and outside the second tank 242 can be shown in FIG. 24(B). The gamma portion is supplied to the toilet body 1〇 substantially in comparison with the amount of water (less than the amount of water when the second tank 241 having a long longitudinal dimension of the side surface is attached). 101103989 58 201237238 The toilet bowl cleaning device 24 of the ninth embodiment of the present invention can easily change the amount of water supplied to the toilet body 10, so that it can be easily washed when the toilet is washed. The toilet body of a plurality of types differs in the amount of water in the clean water. <First Embodiment> The water-washing toilet of the tenth embodiment is different from the seventh embodiment in that the toilet washing device 250 is provided to communicate with the lower portion of the first tank 221 and the injection nozzle 226 as shown in Fig. 25 . The communication path 228 and the pump P which is provided in the communication path 228 and conveys the washing water stored in the first tank 221 to the injection nozzle 226 as a water delivery device. The other configurations are the same as those in the seventh embodiment, and the same components are denoted by the same reference numerals, and the detailed description is omitted. When the flushing toilet is in the toilet washing step, the pump P is driven to start the washing of the toilet, and the washing water stored in the first tank 221 can be sprayed from the injection port 226A of the injection nozzle 226, and the second tank can be sucked. Washing water in 222. Since the washing water is supplied to the injection nozzle 226 by the pump P, it is possible to supply the spray nozzle 226 with a stable high water pressure washing water. Therefore, the jet pump 223 can strongly suck the washing water of the second tank 222 and supply the washing water of a large flow rate to the toilet body 10 stably via the water supply path 224. The fourth invention is not limited to the embodiments 7 to 10 described by the above description and the drawings. For example, the following embodiments are also included in the technical scope of the present invention. (1) In the seventh to tenth embodiments, the second water tank is disposed in the first water tank, but the first water tank and the second water tank are disposed adjacent to each other, and the connection of each of the 101103989 59 201237238 is provided. road. (2) In the seventh to tenth embodiments, the flow path area of the second water tank is made larger than the flow path area of the water supply path, but the flow path area of the second water tank may be made the same as the flow path area of the water supply path. (3) In the seventh to tenth embodiments, the outflow port is provided at the upper end portion of the second water tank to connect the water supply path, but the position of the outflow port may be higher than the position of the inflow port. (4) In the seventh to tenth embodiments, the water supply passage is connected to the upper portion of the toilet bowl portion to spray the washing water onto the surface of the toilet bowl portion, but the water spray port at the downstream end of the water supply passage may be disposed at the same time. The lower end of the bucket or the upstream end of the toilet drain path ejects the washing water along the toilet drain. (5) In the seventh to tenth embodiments, if the water level of the washing water in the first tank is lower than the inlet of the second tank, and the water level of the washing water in the second tank is lowered, the washing water is ended. Although the supply of the spray nozzle is performed, the supply of the washing water to the injection nozzle may be ended when the water level of the washing water in the first tank is higher than the inlet of the second tank.
