Description

马桶及其冲水系统
【技术领域】
本发明涉及卫浴产品技术领域，特别是涉及一种马桶及其冲水系统。
【背景技术】
马桶的发明给人们日常生活带来了很大的便利。传统陶瓷马桶通常采用与陶瓷马桶本体一体设置的陶瓷水箱来盛放冲洗水和洗刷水。陶瓷水箱的高度越低，盛放的冲洗水的量越少，冲洗水和洗刷水的重力势能越小，很难将陶瓷马桶本体冲洗干净。陶瓷水箱的高度越高，盛放的冲洗水和洗刷水的量越多，冲洗水和洗刷水的重力势能越大，虽然可以将马桶陶瓷本体冲洗的较干净，但是高陶瓷水箱造成整个马桶体积大，而且冲洗时费水，与当今节能环保的理念相背而驰。
为了解决这一技术问题，通常采用无陶瓷水箱的马桶结构。这种马桶直接利用外部自来水进行冲洗和洗刷。但是自来水直接进入马桶对马桶进行冲洗和洗刷，通常无法保证足够的水压和流量，从而无法保证洗刷和冲洗干净。
【发明内容】
基于此，有必要提供一种体积小且冲洗效果好的马桶及其冲水系统。
一种马桶的冲水系统，包括：
水箱，内部设置有隔板，所述隔板将所述水箱分隔成洗刷水箱及冲洗水箱，所述洗刷水箱底部开设有进水口，所述冲洗水箱的底部开设有出水口；
单向装置，设置于所述隔板上，所述洗刷水箱内的水通过所述单向装置进入所述冲洗水箱中；
水箱盖，盖设于所述水箱上；
先导式电磁阀，设置于所述水箱盖上，所述先导式电磁阀能够与外部水管连接，所述先导式电磁阀通过第一出水管道与所述洗刷水箱的进水口连通；
水量倍增器，设置于所述洗刷水箱的底部且对应所述进水口，所述水量倍增器与所述第一出水管道相连通，对应所述水量倍增器还设置有水量倍增器管，通过所述水量倍增器的水能够喷射至所述水量倍增器管中，所述水量倍增器管设置于所述洗刷水箱的底部，且所述水量倍增器管的一端与所述洗刷水箱贯通，所述水量倍增器管的另一端能够与洗刷管道相连通；
进水件，设置于所述洗刷水箱内，所述进水件能够与外部水管相连通；
浮筒，设置于所述冲洗水箱内，所述浮筒用于检测所述冲洗水箱内的水位并控制所述进水件的开闭；及
爆破排水阀，用于控制所述冲洗水箱的底部的出水口的开闭，所述爆破排水阀通过第二出水管道与所述先导式电磁阀相连通。
一种马桶，包括：
马桶本体，其底部开设有冲洗口，所述马桶本体的顶部侧壁上开设有洗刷口，所述马桶本体上还设有收容腔；
冲洗管道，一端与所述冲洗口相连通；
洗刷管道，一端与所述洗刷口连通；及
如以上所述的马桶的冲水系统；
其中，所述水箱收容于所述收容腔内，所述先导式电磁阀依次通过所述第一出水管道、进水口、水量倍增器及水量倍增器管与所述洗刷管道的另一端相连，所述先导式电磁阀依次通过第三出水管道及爆破排水阀与所述冲洗管道连通且所述先导式电磁阀通过所述第二出水管与所述出水口相连通。
上述马桶及其冲水系统，取消了设置于马桶本体上的陶瓷水箱，而采用在马桶本体上设置收容腔，用隔板将水箱分隔成洗刷水箱和冲洗水箱，水箱收容于收容腔内，体积小。当需要冲洗马桶时，先导式电磁阀打开，外部自来水依次通过先导式电磁阀、第一出水管道及进水口进入水量倍增器，自来水在快速流动中，周围形成负压，从而将洗刷水箱的存水迅速卷入到水量倍增器管中，洗刷水箱的存水和自来水叠加后从洗刷管道中排出，从而达到水量倍增的效果，洗刷效果更好。同时，外部自来水通过先导式电磁阀及第二出水管道进入爆破排水阀，爆破排水阀由于水压的驱使开始储压，直至爆破排水阀瞬间开启，此时先导式电磁阀关闭，冲洗水箱内的水在短时间内由出水口进入冲洗管道，对马桶进行冲洗，冲洗效果更好，冲洗完后，爆破排水阀关闭。由于爆破排水阀储压需要时间，所以爆破排水阀的开启比洗刷动作延迟，保证洗刷完马桶侧壁后，洗刷水和冲洗水一起冲走。浮筒检测到冲洗水箱内的水位偏低，进水件开启，首先往洗刷水箱内进水，当洗刷水箱内的水达到一定存量时，再通过进水件继续进水时，此时洗刷水箱内的水通过单向装置进入冲洗水箱。浮筒检测到冲洗水箱内的水位正常时，进水件关闭完成进水。因为设置了单向装置，使得冲洗水箱内的存水不能在短时间内回流至洗刷水箱，保证了冲洗效果。

【具体实施方式】
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1至图3，一实施方式的马桶10包括马桶本体100、冲洗管道200、洗刷管道300及马桶的冲水系统400。
马桶本体100可以为陶瓷材质，马桶本体100上还开设有收容腔（图未标），收容腔位于马桶本体100的后端。马桶本体100的底部开设有冲洗口110，冲洗口110与冲洗管道200的一端相连，冲洗管道200的另一端与马桶的冲水系统400相连通。从马桶的冲水系统400中冲出来的水从冲洗管道200进入冲洗口110，对马桶本体100进行冲洗，冲洗完后，冲洗口110中的水可以通过虹吸管道流入下水道中。马桶本体100的顶部侧壁上开设有洗刷口（图未标），洗刷口的数量为多个，且多个洗刷口呈环状分布于马桶本体100的顶部侧壁上。洗刷管道300的一端与洗刷口相连通，洗刷管道300的另一端与马桶的冲水系统400相连通。从马桶的冲水系统400中冲出来的水经过洗刷管道300从洗刷口流出，对马桶本体100的侧壁进行洗刷，洗刷后的水经过冲洗口110与冲洗后的水一起流入下水道中。
请一并参阅图4至图9，马桶的冲水系统400包括水箱410、单向装置420、水箱盖430、先导式电磁阀440、水量倍增器451、水量倍增器管452、进水件460、浮筒470、爆破排水阀480、检测装置491及溢流管492。
水箱410一般的可以为塑胶材质，且水箱410收容于马桶本体100的收容腔内。本实施方式中的水箱410的体积小于传统的陶瓷水箱，所以整体上减小了马桶的体积。水箱410内部设置隔板411，隔板411将水箱410分隔成洗刷水箱412及冲洗水箱413。洗刷水箱412用于盛放洗刷用水，洗刷水箱412底部开设有进水口4121，进水口4121可以通过第一出水管道20与先导式电磁阀440连通。冲洗水箱413用于盛放冲洗用水，冲洗水箱413底部开设有出水口（图未标），出水口与冲洗管道200相连通，冲洗水箱413内的存水通过出水口进入冲洗管道200，通过冲洗口110对马桶本体100进行冲洗。
单向装置420设置在隔板411上，当洗刷水箱412内的进水到达一定高度时，再进水时，水通过单向装置420进入冲洗水箱413内，给冲洗水箱413内进水。设置单向装置420主要是使洗刷水箱412内的水可以短时间顺利进入冲洗水箱413内，而冲洗水箱413内的水无法短时间内回流至洗刷水箱412内，保证冲洗时有足够的水量。
水箱410内的隔板411上开设有缺口，隔板411上对应缺口处设置有开口朝向洗刷水箱412的凹形围挡墙，凹形围挡墙的高度沿远离洗刷水箱412的方向逐渐减小。单向装置420包括固定柱421、单向片固定盖422及单向片423。固定柱421设置于洗刷水箱412对应于缺口处，具体地，固定柱421的数量可以为两个，两个固定柱421分别设置在缺口两边。单向片固定盖422固定于固定柱421上，具体地，可以通过螺钉固定。单向片423可转动地设置于单向片固定盖422上，单向片423覆盖于凹形围挡墙上。
当洗刷水箱412内的水位未到达凹形围挡墙的最低处时，洗刷水箱412内的水无法流入冲洗水箱413，单向片423由于自身重力的影响，覆盖在凹形围挡墙上。当洗刷水箱412内的水位到达凹形围挡墙的最低处并继续进水时，洗刷水箱412内的水迫使单向片423转动，洗刷水箱412内的水可以快速进入冲洗水箱413中，给冲洗水箱413内进水。当洗刷马桶后，洗刷水箱412内的水位下降，由于单向片423的存在，冲洗水箱413内的水压住单向片423，单向片423无法转动，所以冲洗水箱413内的水无法快速回流至洗刷水箱412内。
具体地，还可以在单向片423上开设连通洗刷水箱412和冲洗水箱413的通孔4231。当出现洗刷完马桶，却没有冲洗马桶时，此时冲洗水箱413内的水位并未下降，浮筒470检测到冲洗水箱413内的水位并未下降，就不会打开进水件460，因而无法重新给洗刷水箱412进水。所以，在单向片423上开设通孔4231，出现上述情况时，冲洗水箱413内的存水可以缓慢回流至洗刷水箱412，造成冲洗水箱413内的水位下降，浮筒470检测到冲洗水箱413内的水位下降后，控制进水件460开启。因为该通孔4231的大小远小于单向片423，所以冲洗水箱413内的存水并不会快速回流至洗刷水箱412内，保证了冲洗的水量。
请参阅图1及图7，水箱盖430盖设于水箱410上。具体地，水箱盖430可以为塑胶材质。水箱盖430可以通过螺钉固定在水箱410上。
先导式电磁阀440设置于水箱盖430上。先导式电磁阀440为一入两出式结构。先导式电磁阀440与外部水管40连接，外部自来水通过外部水管30进入先导式电磁阀440中，具体地，先导式电磁阀440的入口与外部水管30连接。先导式电磁阀440通过第一出水管道20与洗刷水箱412的进水口4121连通。具体地，先导式电磁阀440的其中一出口通过第一出水管道20与洗刷水箱412的进水口4121连通，先导式电磁阀440的另一出口通过第二出水管道（图未示）与爆破排水阀480相连通。具体到本实施方式中，先导式电磁阀440的与马桶本体100的底部之间的高度高于马桶本体100的顶部与马桶本体100的底部之间的高度，即，先导式电磁阀440设置的高度高于马桶本体100，防止马桶堵塞时，马桶本体100内的污水回流至先导式电磁阀440，进而防止污水回流至自来水管中。
请一并参阅图7至图10，水箱盖430上还设置有贯穿水箱盖的导向管431，导向管431用于将水量倍增器管452中的水导向洗刷管道300中。导向管431靠近水量倍增器管452的一端开设有空气断流缺口4311，导向管431通过空气断流缺口4311可与外界相通。空气断流缺口4311的设置高度高于洗刷水箱412的液面高度。冲水系统还包括密封软胶432，密封软胶432包括密封圈本体4321及设置于密封圈本体4321上的尾翼4322。导向管431的一端通过密封软胶432与水量倍增器管452连接，导向管431的另一端与洗刷管道300连接，尾翼4322对应设置于空气断流开口4311处。
请继续参阅图7至图10，水量倍增器451设置于洗刷水箱412的底部且对应于进水口4121。具体到本实施方式中，水量倍增器451主要采用文氏管原理。水量倍增器451与第一出水管道20相连通，对应水量倍增器451还设置有水量倍增器管452，通过水量倍增器451的水能够喷射至水量倍增器管452。水量倍增器管452设置于洗刷水箱412的底部，且水量倍增器管452的一端与洗刷水箱412贯通，即洗刷水箱412内的存水可以流入水量倍增器管452中，水量倍增器管452的另一端与洗刷管道300相连通。外部自来水通过先导式电磁阀440、第一出水管道20进入水量倍增器451中时，自来水在快速流动中，周围形成负压，从而将洗刷水箱412的存水迅速卷入到水量倍增器管452中，达到水量倍增的效果。
请参阅图8，当处于洗刷状态时，水从水量倍增器451流进水量倍增器管452，在水压作用力下，位于密封软胶432上的尾翼4322密封空气断流缺口4311。空气断流缺口4311的作用是防止停止洗刷时，洗刷水箱412内的存水液面高于洗刷口的液面,虹吸会将洗刷水箱412的存水带走,造成水量损失。请参阅图9，在停止洗刷时，密封软胶432上的尾翼4322由于失去水压作用力，不再密封空气断流缺口4311，空气从空气断流缺口进入导向管431，隔断虹吸力，有效防止虹吸，成功避免水量流失，此结构设计简单巧妙，适用范围广。
请继续参阅图4至图6，进水件460设置于洗刷水箱412内，进水件460与外部水管30相连通。进水时，通过进水件460先给洗刷水箱412内进水，到达一定水位时，水通过单向片423流入冲洗水箱413。浮筒470设置于冲洗水箱413内，浮筒470用于检测冲洗水箱413内的水位高低，并控制进水件460的开闭。当浮筒470检测到冲洗水箱413内的水达到一定水位时，控制进水件460关闭。当浮筒470检测到冲洗水箱413内的水位低于设定值时，控制进水件460开启。由于浮筒470设置在冲洗水箱413内，当先导式电磁阀440开启时，自来水通过水量倍增器451带动洗刷水箱412内的存水流向洗刷口，同时洗刷水箱412内的液面降低，此时由于洗刷水箱412与冲洗水箱413之间设置有单向装置420，使冲洗水箱413的液面高度保持不变，因此进水件460暂时不进水，自来水全部用于水量倍增器451，不会因为开启进水件460而降低水量倍增器451的动态水压。
具体到本实施方式中，进水件460上连接有一塑胶软管（图未示），该塑胶软管的另一端与冲洗管道200相连通，当冲洗和洗刷动作完成后，马桶底部存有一定水量用于水封，防止臭气，当水量不够时，该塑胶软管可以用于补水，对马桶进行水封。
请一并参阅图11至图15，爆破排水阀480用于控制冲洗水箱413的底部的出水口的开闭，爆破排水阀480通过第二出水管道与先导式电磁阀440相连通。具体地，爆破排水阀480主要包括底座481、活塞缸482、活塞复位弹簧4823、储能弹簧483、排水阀盖体484、连接杆支架4851、连接杆支架复位弹簧4852、连接杆4853、连接片4854、密封组件486、定位支架487及扳机机构488。
底座481设置于冲洗水箱413的底部且对应于出水口。底座481上开设有排水口4811，冲洗水箱413内部的存水是通过该排水口4811再经过冲洗水箱413上的出水口，再流入冲洗管道200内对马桶本体100进行冲洗。围绕排水口4811设置有多根定位柱4812，定位柱4812用于支撑活塞缸482。底座481大致为圆形，底座481的外侧壁上还形成有加强筋4813，加强底座481的强度。溢流管492与排水口4811相连通，从溢流管492流出的清水经过排水口4811流入冲洗管道200，从而防止水溢出水箱410。
活塞缸482设置于定位柱4812上。活塞缸482包括活塞缸本体4821、活塞4822、活塞复位弹簧4823及活塞密封圈4824。活塞缸本体4821的侧面凸出形成有活塞口，活塞口通过第二出水管道与先导式电磁阀440相连通，外部的清水通过活塞口进入活塞缸本体4821内部。活塞4822的外表面上形成有凸柱48221以及凸块48222，储能弹簧483套设于凸柱48221上。在凸柱48221的外周围还形成有环形护栏48223，储能弹簧483套设于凸柱48221上且一端收容于环形护栏48223内。具体到本实施方式中，凸柱48221为中空结构，活塞复位弹簧4823收容于凸柱48221内。具体到本实施方式中，凸柱48221的数量为两个，对称设置于活塞4822上。凸块48222的数量也为两个，对称地设置于活塞4822上。相应的，储能弹簧483也设置两个。活塞复位弹簧4823也设置两个。
排水阀盖体484设置于活塞缸本体4821上。活塞密封圈4824的一端固定于活塞4822上，其另一端固定在排水阀盖体484上。当活塞缸本体4821内充满水后，活塞密封圈4824与排水阀盖体484内壁紧密贴合。具体到本实施方式中，活塞密封圈4824为弹性密封圈，当活塞缸本体4821内部充满水后时，活塞密封圈4824处于张紧状态，而排水阀盖体484的形状与活塞密封圈4824张紧后的形状相适配，活塞密封圈4824与排水阀盖体484内壁紧密贴合，可以减小水压对活塞密封圈4824的冲击，延长活塞密封圈4824的使用寿命。定位支架487设置于排水阀盖体484上。
连接杆支架4851穿设于凸柱48221上，储能弹簧483的一端与连接杆支架4851相抵触。连接杆支架4851上还形成有支架柱（图未示），连接杆支架复位弹簧4852套设于支架柱上，且一端与定位支架487相抵触。连接杆4853穿设于活塞缸本体4821上，连接杆4853的一端固定在连接杆支架4851上。具体地，可以在连接杆4853的一端设置连接片4854，连接片4854固定在连接杆4853远离密封组件486的一端，用于防止连接杆4853脱离连接杆支架4851。
密封组件486设置于连接杆的另一端，且密封组件486位于活塞缸本体4821的底部，密封组件486能够随着连接杆4853的移动而移动，且密封组件486能够密封排水口4811。密封组件486包括第一密封圈4861和第二密封圈4862。第一密封圈4861大致为圆形，第一密封圈4861中部开设有通孔。第二密封圈4862中部凸出形成凸台，凸台与通孔相适配。第一密封圈4861的外径比第二密封圈4862的外径大，形成台阶结构，台阶结构与底座481的排水口4811口壁密切接触，增大密封性能。
请一并参阅图16至图19，具体到本实施方式中，可以设置两个扳机机构488，两个扳机机构488轴对称地设置在排水阀盖体484上。扳机机构488包括触发板4881、定位轴4882、扭簧4883、扳机4884、转动轮4885及转动轮复位弹簧4886。扭簧4883分别抵触触发板4881及扳机4884，扳机4884能够沿定位轴4882转动。转动轮4885的周缘上突出形成有第一定位凸块48851及第二定位凸块48852，第一定位凸块48851与扳机4884相抵触，第二定位凸块48852与连接杆支架4851的顶面相抵触。转动轮4885可转动地设置于定位支架487上，转动轮复位弹簧4886一端固定于转动轮4885上，另一端固定于定位支架487上。
外部清水通过先导式电磁阀440进入活塞缸482内部后，在水压的作用下，活塞4822向上运动，这时连接杆4853和连接杆支架4851并不能运动，储能弹簧483被压缩开始储能。当活塞4822运动到预定位置，凸块48222与扳机4884接触时，迫使扳机4884沿定位轴4882转动，脱离转动轮4885的第一定位凸块48851，转动轮4885在没有扳机4884的压迫时，也发生转动，从而第二定位凸块48852脱离连接杆支架4851的顶面。这时连接杆支架4851在储能弹簧483的作用下立即动作，带动连接杆4853向上移动，从而带动密封组件486向上移动，排水口4811迅速打开，冲洗水箱413内的水经过排水口4811对马桶进行冲洗。在关闭先导式电磁阀440时，活塞复位弹簧4823使活塞往下移动进行复位，在转动轮复位弹簧4886和扭簧4883的作用下，转动轮4885和扳机4884按顺序复位，并在转动轮4885的压力辅助下，活塞缸4882内的水从活塞口压出，连接杆支架复位弹簧4852作用使连接杆支架4851复位，连接杆4853往下移动，密封组件486关闭排水口4811，完成冲洗。
检测装置491包括磁铁4911及霍尔开关4912。磁铁4911设置于爆破排水阀480的顶部，霍尔开关4912设置于水箱盖430上。霍尔开关4912的位置与磁铁4911的位置相对应且可相互作用，用于检测爆破排水阀480是否开启。当爆破排水阀480开启时，爆破排水阀480的顶部向上移动，从而磁铁4911与霍尔开关4912之间的间距减小。当检测到爆破排水阀480开启时，可适当延迟关闭先导式电磁阀440，以保证更好的冲洗效果。
溢流管492设置于冲洗水箱413的底部，且溢流管492的高度小于冲洗水箱413的高度，溢流管492与爆破排水阀480的排水口4811连通。当冲洗水箱413内的存水达到一定高度后，会从溢流管492流出，设置溢流管492可以防止冲洗水箱413内的溢出。
请一并参阅图20，上述马桶及其冲水系统，取消了设置于马桶本体100上的陶瓷水箱，而采用在马桶本体100上设置收容腔，用隔板411将水箱410分隔成洗刷水箱412和冲洗水箱413，水箱410收容于收容腔内，体积小。当需要冲洗马桶时，步骤S10，先导式电磁阀440打开，外部自来水依次通过先导式电磁阀440、第一出水管道20及进水口4121进入水量倍增器，自来水在快速流动中，周围形成负压，从而将洗刷水箱412的存水迅速卷入到水量倍增器管452中，步骤S21，洗刷水箱412的存水和自来水叠加后从洗刷管道300中排出，从而达到水量倍增的效果，洗刷效果更好。同时，步骤S22，外部自来水通过先导式电磁阀440及第二出水管道进入爆破排水阀480，爆破排水阀480由于水压的驱使开始储压，步骤S31，直至爆破排水阀480瞬间开启，此时先导式电磁阀440关闭，步骤S40，冲洗水箱413内的水在短时间内由出水口进入冲洗管道200，对马桶进行冲洗，冲洗效果更好，冲洗完后，步骤S50，爆破排水阀480关闭。由于爆破排水阀480储压需要时间，所以爆破排水阀480的开启比洗刷动作延迟，保证洗刷完马桶侧壁后，洗刷水和冲洗水一起冲走。步骤S60，浮筒470检测到冲洗水箱413内的水位偏低，进水件460开启，首先往洗刷水箱412内进水，当洗刷水箱412内的水达到一定存量时，再通过进水件460继续进水时，此时洗刷水箱412内的水通过单向装置420进入冲洗水箱413。步骤S70，浮筒470检测到冲洗水箱413内的水位正常时，进水件460关闭完成进水。因为设置了单向装置420，使得冲洗水箱413内的存水不能在短时间内回流至洗刷水箱412，保证了冲洗效果。
上述马桶及其冲水系统还具备不同水压下保持用水量恒定的功能。当需要冲洗马桶时，先导式电磁阀440打开，当检测到爆破排水阀480开启后，先导式电磁阀440关闭，则冲洗马桶的用水总量为：V=V冲洗+V洗刷，V冲洗表示冲洗水箱的容量，V洗刷表示完成一次冲洗用的洗刷水量。而V洗刷=F*t，其中F表示流量，T表示先导式电磁阀的开启时间。当自来水水压较高时，流量F增加，而先导式电磁阀440开启时间t减少。当自来水水压交底时，流量F减少，而先导式电磁阀440开启时间t延长。这样，总的洗刷用水量保持恒定，因此总用水量保持恒定。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
