详述
下文中将结合附图对本公开的实施例进行详细说明。在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。
目前，马桶后置排污系统中所应用到的排污管大都采用两头等直径的直角弯管，在排污过程中容易出现污物挂在开口边角和开口边角影响排污流速的情况。
另外，从流体流动分析的角度出发，流体在流动过程中遇到直角转弯的地方，直角位置会形成湍流，从而改变和影响整体的流速。在排污管的应用中会造成的影响则体现在影响排污效率及排污流动的排污效果；而且在排污过程中，由于开口边角的存在，在排污过程中则有概率出现边角口挂污的情况。
本公开实施例提供的排污管、排污系统和马桶，可以解决上述问题。
如图1至图4所示，本公开的一个实施例提供了一种排污管2，包括：进污管段21和排污管段22。
其中，进污管段21设置为与马桶的排污盒1可转动连接，进污管段21设有进污口211。
排污管段22与进污管段21相连，并相对于进污管段21弯折设置。排污管段22远离进污管段21的一端设有排污口221，排污口221的面积大于进污口211的面积。
本公开实施例提供的排污管2，包括进污管段21和排污管段22。进污管段21设有进污口211，供马桶座体200盆腔202内的污物进入。排污管段22 设有排污口221，供排污管2内的污物排出。排污管段22与进污管段21相连，并相对于进污管段21弯折设置，因而排污口221的位置与进污口211的位置会产生高度差，便于污物在重力的作用下排出。
由于进污管段21能够与马桶的排污盒1可转动连接，在排污过程中可以带动排污管段22由上向下转动，以利用重力势能将排污管2内的污物排入排污盒1内，污物会经排污盒1的污物出口112进入移位器，进而进入外界排污通道中，如图8和图9所示。
相较于进污口211与排污口221直径相等的方案，本方案设置排污口221的面积大于进污口211的面积，相当于增加了排污口221的面积，因而有利于提高排污效率，降低污物挂在排污口221的概率。
在一种示例性的实施例中，进污管段21为镜面对称结构。进污管段21的对称面S1沿排污管段22的延伸方向延伸，如图2所示。
在一个示例中，进污口211设置为圆形。排污口221设置为异形，如图2所示。
进污管段21采用镜面对称结构，且进污口211为圆形，结构较为规整，便于加工成型；也有利于简化进污管段21与排污盒1之间的密封结构。
在旋转排污过程中，排污管段22的初始位置一般为竖直状态，如图8所示，即排污口221水平朝上的状态。因此，该状态下排污管段22的延伸方向即为竖直方向。由于进污管段21的对称面沿排污管段22的延伸方向延伸，因此当排污管2处于初始位置时进污管段21的对称面即为进污管段21沿竖直方向延伸的中垂面。
将排污口221设置为异形，只需在现有圆形的基础上，使排污口221适当向外扩张，即可保证排污口221的面积大于进污口211的面积。而设计过程中，只需将排污管段22的末端部位适当向外扩张变形即可，这样便于在现有排污管2的基础上进行改进，在排污管2整体体积基本不变的情况下，增加排污口221的面积，以提高排污效率和排污效果。
在一种示例性的实施例中，如图4所示，以进污管段21的对称面为分界面212，将排污管段22分为倾倒部222和非倾倒部223。排污管2在转动排 污过程中向倾倒部222所在的一侧转动。
其中，倾倒部222靠近排污口221的区域设有导流斜面2221，如图4所示。沿着靠近排污口221的方向，导流斜面2221朝远离分界面212的方向倾斜延伸。
由于排污管2在转动排污过程中只需向一侧转动，即向倾倒部222所在的一侧转动，污物在重力的作用下会尽可能沿着倾倒部222的内壁面流动至排污口221排出。因此，在倾倒部222靠近排污口221的区域设置导流斜面2221，相当于在传统的规则圆柱形结构的开口处增加了倾斜口，可以对污物起到较好的引导作用，有利于提升排污流速，促使污物快速、顺畅地流动至排污口221处排出，进而提高排污效率。
并且，导流斜面2221的设置，使得排污口221形成异形开口，相较于传统的圆形开口面积更大，也有利于提升排污口221的排污流量，进而提升排污效率。
而排污流速和排污流量的增加，可以降低污物挂在排污口221处的概率，从而提高排污效果。
在一种示例性的实施例中，导流斜面2221相对于分界面212的倾斜角度在10°至20°的范围内，如图5所示。
将导流斜面2221相对于分界面212的倾斜角度限定在10°至20°的范围内，避免了导流斜面2221倾斜角度过大导致排污管段22占用空间过多，排污管段22占用空间增加，会导致排污盒1体积随之增加，不利于排污盒1的小型化。
如图5所示，在一个对比例中，导流斜面2221相对于分界面212的倾斜角度增加至30°，则排污口221在左右方向上的宽度会增加a1。在另一个对比例中，导流斜面2221相对于分界面212的倾斜角度增加至45°，则排污口221在左右方向上的宽度会增加a2。这样，排污管2占用的空间会随之增大。如图12所示，当排污管2转动相同角度到达至排污位置时，因导流斜面2221倾斜角度的增加，会导致排污盒1的体积也需要相应增大，因而不利于排污盒1的小型化。
因此，本方案将导流斜面2221相对于分界面212的倾斜角度限定在10°至20°的范围内(如10°、13°、15°、18°、20°等)，有利于排污管2在本身体积变化不大的基础上提升排污效率和排污效果，也有利于排污盒1的小型化，进而有利于提升排污系统100的灵活性和适配性。
在一种示例性的实施例中，排污管段22包括直管段224和异形管段225，如图1所示。直管段224与进污管段21相连。异形管段225与直管段224相连，异形管段225靠近排污口221的位置设有导流斜面2221。
直管段224可以采用常规的圆柱形，便于与进污管段21平滑相接。而异形管段225设置导流斜面2221，可以提高排污效率和排污效果。
并且这样设计，使得导流斜面2221仅仅位于排污管段22的末端部位，导流斜面2221的长度相对较短，因而排污管段22的体积相较于规则的圆柱形改变较小，故而有利于排污管2在本身体积变化不大的基础上提升排污效率和排污效果，也有利于排污盒1的小型化，进而有利于提升排污系统100的灵活性和适配性。
在一种示例性的实施例中，排污管段22为镜面对称结构。排污管段22的对称面S2与进污管段21的对称面S1相互垂直，如图2所示。
如图2所示，结合附图中的方向，排污管段22在前后方向上镜面对称，排污管段22的对称面S2沿上下方向和左右方向延伸。进污管段21在左右方向上镜面对称，进污管段21的对称面S1沿上下方向和前后方向延伸。因此，排污管段22的对称面S2与进污管段21的对称面S1相互垂直。
这样，排污管段22的形状也较为规则，便于加工成型。并且，这样也便于排污管段22受力均衡，有利于提高排污管2在转动过程中的稳定性。
在一种示例性的实施例中，在进污管段21的对称面上，进污口211的中心轴线与排污口221的中心轴线相交，且夹角θ小于90°，如图3所示。
这样，进污口211的进污方向与排污口221的排污方向之间形成锐角，而不是传统直角弯管的直角。
由于排污管2在初始位置时，如图8和图13所示，排污管段22处于竖直状态，因此排污口221的中心轴线也沿竖直方向延伸。由于进污口211的 进污方向与排污口221的排污方向之间形成锐角，而不是传统直角弯管的直角，因此进污口211的中心轴线倾斜向下延伸，而不是沿水平方向。这样便于盆腔202内的污物在重力的作用下快速进入排污管2内，有利于污物的导流流入，从而进一步提高排污效率和排污效果。
并且，当排污管2转动至排污位置时，如图9、图11和图14所示，排污管2形成类似于旋转滑梯的双斜度排污滑路，具有两道斜坡，盆腔202内的污物先经进污口211进入第一道斜坡(即进污管段21)，然后再转弯进入第二道斜坡(即排污管段22)快速排出，从而保证马桶更好更快地进行排污。
在一种示例性的实施例中，在进污管段21的对称面上，进污口211的中心轴线与排污口221的中心轴线的夹角θ在75°至85°的范围内，如75°、80°、85°。
这样也有利于避免污物在由进污管段21转动流入排污管段22时出现急转弯，因而排污效率和排污效果更好。
在一种示例性的实施例中，排污管段22与进污管段21圆弧过渡连接，如图3所示。
这样也有利于避免污物在由进污管段21转动流入排污管段22时出现急转弯，因而排污效率和排污效果更好。
在一种示例性的实施例中，排污管2还包括：连接部24，与进污管段21相连，连接部24设置为连接用于带动排污管2转动的驱动装置3，连接部24的中轴线与进污口211的中心轴线重合，如图3所示。
这样，装配完成后，驱动装置3带动连接部24转动，进而可以带动排污管2整体相对排污盒1绕进污口211的中心轴线转动。
在一种示例性的实施例中，排污口221与进污口211之间的最小距离H大于或等于50mm，如图3所示。
当排污管2处于排污初始位置时，排污口221的最低点的位置决定了马桶内水封面的上限，进污口211的最高点的位置决定了马桶内水封的下限。而排污口221的最低点的位置与进污口211的最高点的位置之间的高度差等于排污口221与进污口211之间的最小距离。因此，将排污口221与进污口 211之间的最小距离限定在大于或等于50mm的范围内，可以保证马桶内的水封高度H0(或者叫水封深度)不低于50mm，如图13所示，以满足国家标准要求。
在一种示例性的实施例中，进污口211的直径d在55mm至65mm的范围内，如图3所示。
传统排污管2的管径一般在45mm至50mm的范围内，进污口211的直径等于排污管2的管径，也在45mm至50mm的范围内。而本方案将排进污口211直径d限定在55mm至65mm的范围内(如55mm、60mm、65mm等)，进污口211面积明显增大，而排污口221的面积大于进污口211的面积，因此整个排污管2的管径增大，可以更好地提升冲刷管道的排污性能，也有利于节约排污用水，实现环保节水的目的。而排污管2在体积上的变化不大，因而兼顾了结构、体积及环保等多方面因素。
在一种示例性的实施例中，排污管2的管路长度在130mm至140mm的范围内，如130mm、132mm、135mm、138mm、140mm等。
传统的虹吸管管路长度大部分都大于700mm，而本方案中排污管2的管路显著缩短。大管径配合短管路，能够使本公开实施例的排污管2的排污性能更加稳定可靠，更加不易发生堵塞。
在一种示例性的实施例中，进污管段21远离排污管段22的一端还设有用于安装密封件14的密封凸台23，如图1、图2和图3所示。密封凸台23呈环状，且密封凸台23的内直径大于进污口211的直径。
密封凸台23的设置，便于密封件14的安装，有利于实现排污管2、排污盒1以及马桶盆腔202之间的密封配合，防止污物发生泄露。
在一种示例性的实施例中，密封凸台23的外壁面靠近排污口221的部位与排污管段22的外壁面相接，如图3所示。
这样，进污管段21的长度非常小，进污管段21与排污管段22的非倾倒部223相连的部位甚至可以忽略不计，而与排污管段22的倾倒部222相连的部位基本上为圆弧形。因此，进污管段21大致上相当于一段过渡管接头。这样有利于缩短排污管2的管路长度，进而有利于提升排污管2的排污性能。
如图6所示，本公开实施例还提供了一种排污系统100，包括：排污盒1、如上述实施例中任一项的排污管2和驱动装置3。
排污管2与排污盒1转动连接。驱动装置3与排污管2相连，设置为驱动排污管2相对排污盒1转动。
本公开实施例提供的排污系统100，因包括上述实施例中任一项的排污管2，因而具有上述任一实施例所具有的一切有益效果，在此不再赘述。
在一种示例性的实施例中，排污盒1包括盒主体11和盒盖12，如图6所示。盒主体11设有转动连接孔111，如图6所示。盒盖12与盒主体11盖合连接。盒盖12与盒主体11之间设有密封圈13，如图6所示，排污管2与排污盒1之间设有密封件14。盒盖12设有连接孔121，排污管2设有连接部24。驱动装置3通过连接孔121与连接部24相连，设置为驱动排污管2转动。驱动装置3可以为电机。
该排污系统100的排污原理如下(如图8至图9所示)：
旋转排污时，马桶座体200盆腔202内的污物进入排污管2，排污管2在驱动装置3的驱动下由初始位置(即排污口221朝向正上方的位置，如图8和图13所示)向右转动100°至120°达到排污位置(如图9和图14所示)，污物由排污口221排出经排污盒1的污物出口112排出。
排污动作完成后，通过排污管2排出的污物通过排污盒1的污物出口112流入移位器后导入外界排污通道，移位器与排污盒1之间设有密封圈。而排污管2则在驱动装置3的驱动下复位至初始位置(如图10所示)，待下次排污功能时再次应用。
在一种示例性的实施例中，排污系统100还包括清洗装置4，如图6所示。清洗装置4与排污盒1相连，设置为向排污盒1内部喷洒清洗液，因而能够对排污盒1起到清洗作用，有利于排出残留或挂留在排污盒1内的污物，从而提高排污盒1的洁净度，保持良好的排污效果。
在一种示例性的实施例中，清洗装置4包括进液管41和喷洒件42。进液管41与排污盒1连通。喷洒件42与进液管41相连，设置为向排污盒1内喷洒清洗液。
这样，进液管41可以与外部清洗源(如外部水源)连通，向排污盒1引入清洗液，通过喷洒件42将清洗液喷洒至排污盒1内，对排污盒1起到清洗作用，有利于排出残留或挂留在排污盒1内的污物，从而提高排污盒1的洁净度，保持良好的排污效果。
如图7、图16、图18、图19和图20所示，本公开实施例还提供了一种马桶，包括：马桶座体200和如上述实施例的排污系统100。
其中，如图13和图14所示，马桶座体200设有盆腔202，盆腔202设有排污出口204。排污系统100的进污口211与排污出口204连通，且排污出口204的中心轴线与进污口211的中心轴线共线。
本公开实施例提供的马桶，因包括上述实施例中的排污系统100，因而具有上述一切有益效果，在此不再赘述。
在一种示例性的实施例中，马桶座体200设有与盆腔202连通的冲水口2002，如图15和图16所示。冲水口2002可以采用管接头的形式，将管接头安装在马桶座体200上的对应位置，并通过管路与分水阀206的第一出水口对接。
如图15、图16、图17和图18所示，马桶还包括：分水阀206。分水阀206设有进水口、第一出水口和第二出水口。第一出水口及第二出水口择一与进水口连通。进水口设置为连接水源。第一出水口设置为与冲水口2002连通以向盆腔202供水。第二出水口设置为与排污系统100的清洗装置4连通以向清洗装置4供水。
当马桶需要冲刷排污时，将进水口与第一出水口导通，水经分水阀206后进入马桶的冲水口2002，进而进入马桶盆腔202内，连同盆腔202内的污物一起进入排污管2，随排污管2向下转动排出排污管2，随污物经排污盒1的污物出口112进入移位器2006，最后进入外界排污通道中。
当冲刷排污完毕时，分水阀206可以切换到另一水路，将进水口与第二出水口导通，水经分水阀206后进入清洗装置4，经清洗装置4喷洒至排污盒1内部，对排污盒1内部进行清洗，从而提高排污盒1的清洁度，使排污系统100能够保持较好的排污效果。
此外，在马桶冲刷排污前，也可以将进水口与第一出水口导通，水经分水阀206后进入马桶的冲水口2002，进而进入马桶盆腔202内，对盆腔202的内壁面进行润湿处理，有利于后续冲刷排污过程中污物及时滑落，减少残留或挂留在盆腔202内壁面上的污物。
在排污管2转动排污前，也可以将进水口与第二出水口导通，使得水经分水阀206后进入清洗装置4，经清洗装置4喷洒至排污盒1内部，对排污盒1内壁面进行润湿处理，有利于后续冲刷排污过程中污物及时滑落，减少残留或挂留在排污盒1内壁面上的污物。
这样，通过控制分水阀206内部水路的选择性导通，可以为马桶的不同功能供水。相较于设置多个水阀分别与冲水口2002及清洗装置4连通的方案，本方案有利于减少马桶的部件数量和管路长度，进而简化马桶的结构，降低产品成本。
在一种示例性的实施例中，马桶座体200设有多个分水口，多个分水口设在盆腔202的顶部。冲水口2002通过多个分水口与盆腔202连通。
换言之，马桶座体200顶部设有进水通道，水经冲水口2002进入进水通道，经多个分水口流出进水通道进入盆腔202内，可以对盆腔202的内壁面进行清洗、润湿，也可以提升马桶的水封面的位置，进而增加排污管2内的污物及液体的重力势能。
由于本公开实施例的马桶，主要通过驱动装置3驱动排污管2向下旋转运动将污物排出，原理主要是依靠管内污物及液体的重力势能和下落惯性实现下落排污，因此盆腔202顶部分水口提供的水，即可起到提升排污效果的作用，而无需在盆腔202底部设置喷射口以利用喷射口的大水流将污物冲入排污管2内。
因此，本公开实施例提供的马桶，可以取消盆腔202底部的喷射口，只保留盆腔202顶部的分水口，在保证排污效果的前提下，可以减小噪音，从而有利于提高用户的使用体验。
由于盆腔202顶部分水口流出的水沿着盆腔202内壁面向下流动，水流强度相对较小，噪音也较小；而盆腔202底部喷射口的水流大，噪音也较大。
其中，现有的无水箱或者有水箱马桶，基本都是通过盆腔202顶部的分水口出水来清洗盆腔202内壁面，通过盆腔202底部的喷射口喷水来排除排泄物，并且利用陶瓷座体本身的S弯管路产生虹吸功能，实现排污功能。由于排污主要利用喷射口大水流喷射把排泄物喷进S弯管，因而使用噪音大。
而本公开实施例提供的马桶，马桶座体200只保留了盆腔202顶部的分水口(或者叫刷圈的清洗喷水口)，取消了盆腔202底部的喷射口，这样能有效地减小马桶排污冲刷过程的噪音，提高用户的使用体验。并且，通过驱动装置3控制排污管2的翻转直接排污，取消了现有虹吸式马桶的S弯管，可以缩短排污路径，实现快速排污功能，且排污效果好。
在一种示例性的实施例中，马桶还包括：储水箱210和水泵208，如图15和图16所示。水泵208的输入端与储水箱210连通，水泵208的输出端与进水口连通，用于将储水箱210内的水泵入分水阀206。
这样，通过控制水泵208的启停，即可控制马桶内水路的通断；通过控制分水阀206，即可控制分水阀206内水路的切换，进而有利于实现自动化控制。
在一种示例性的实施例中，马桶座体200设有安装腔2004，如图15和图16所示，安装腔2004位于盆腔202的后侧。排污系统100、分水阀206的至少一部分、储水箱210的至少一部分和水泵208位于安装腔2004内。
这样，相较于将储水箱210设在马桶座体200上方的方案，本公开实施例的马桶，整体结构较为紧凑，体积相对较小，既便于储存、运输，也可以减小马桶的安装空间，有利于减少对卫生间空间的占用。
