Description

马桶及其冲刷*** 技术领域
本文涉及但不限于卫浴产品领域，特别涉及马桶及其冲刷***。
背景技术
一些主流的智能马桶冲水平台有：1、自来水直冲平台，2、低水箱平台，3、辅佐加泵(小型泵)后的平台。第一种自来水直冲平台，利用自来水水压和流量，先进行胆包洗圈，然后切换到喷射口喷射，再到洗圈补水；第二种低水箱平台，利用文氏洗圈或者自来水洗圈，水箱水喷射；第三种辅佐加泵后的平台，利用辅佐泵对前面两个冲水平台进行辅佐补充，通过增加增压泵来实现冲水。
这几种冲水平台需要的用水量大，并且均做不到一级水效。
发明概述
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本申请实施例提供了一种马桶及其冲刷***，可同时进行喷射和洗刷出水，提高了马桶的冲刷效果，且节省了冲刷用水量，提高了马桶的水效。
一种马桶的冲刷***，包括冲刷控制装置，所述冲刷控制装置包括壳体、防虹吸阀和喷射开关阀，所述壳体具有进水口、洗刷出水口和喷射出水口，所述防虹吸阀设置在所述进水口处并控制所述进水口的开闭，所述喷射开关阀设置在所述喷射出水口处并控制所述喷射出水口的开闭，所述洗刷出水口处于常开状态。
一种马桶，包括马桶本体，所述马桶本体具有洗刷口和喷射口，所述马桶还包括上述的马桶的冲刷***，所述冲刷***的洗刷出水口与所述洗刷口连通，所述冲刷***的喷射出水口与所述喷射口连通。
本申请实施例提供的马桶的冲刷***，可控制马桶的冲刷过程。冲刷控 制装置中，壳体的进水口设有防虹吸阀，使得水通过防虹吸阀再供给洗刷出水口和喷射出水口，在配备有水箱的情形下，可以保证水箱内的水不会虹吸走。在马桶冲刷过程中，洗刷出水口处于常开状态，使得洗刷出水口持续出水对马桶本体进行洗刷；喷射出水口通过喷射开关阀控制开闭，在喷射出水口打开时，洗刷出水口和喷射出水口可同时出水，增大了冲刷时的瞬时水流量，使冲刷过程的虹吸作用更早的发生，以此减少了虹吸作用发生前的水量损失，且由于瞬时水流量的增加，使得产生的喷射力度更大，有助于更快的完成虹吸过程，减少喷射用水量，以此节省了单次冲刷过程的用水量，提高了马桶的冲刷效果，使得马桶可达到一级水效。
本申请实施例的其它特征和优点将在随后的说明书中阐述。

详述
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
如图1-图4所示，本申请实施例提供了一种马桶的冲刷***，包括冲刷控制装置，冲刷控制装置包括壳体1、防虹吸阀2和喷射开关阀3，壳体1具有进水口103、洗刷出水口104和喷射出水口105，防虹吸阀2设置在进水口103处并控制进水口103的开闭，喷射开关阀3设置在喷射出水口105处并控制喷射出水口105的开闭，洗刷出水口104处于常开状态。
在虹吸式马桶的冲刷过程中，当冲入马桶的水通过虹吸管道的最高点后会发生虹吸效应，在虹吸作用下，污水能够从排污口排出马桶。本申请发明人在实践中敏锐的发现，如果在冲刷过程中，能够让虹吸作用更早的到来、更快的完成，就能够缩短整个冲刷过程的时间，并能够减少自冲刷过程开始至虹吸作用到来这段时间内的水量损失，可以减少单次冲刷的用水量。
本申请实施例中马桶的冲刷***可控制马桶的冲刷过程。冲刷控制装置中，壳体1的进水口103设有防虹吸阀2，使得水通过防虹吸阀2再供给洗刷出水口104和喷射出水口105，当该马桶的冲刷***还包括水箱6时，能够保证水箱6内的水不会被虹吸走。冲刷控制装置的洗刷出水口104和喷射出水口105可以分别与马桶本体5的洗刷口502和喷射口501连通，其中，洗刷出水口104处于常开状态，使得在马桶冲刷过程中，洗刷出水口104始终出水对马桶本体5进行洗刷；喷射出水口105通过喷射开关阀3控制开闭， 喷射出水口105打开时，洗刷出水口104和喷射出水口105可同时出水，增大冲刷时的瞬时水流量，使冲刷过程的虹吸作用更早的发生，以此减少了虹吸作用发生前的水量损失，且由于瞬时水流量的增加，使得产生的喷射力度更大，有助于更快的完成虹吸过程，减少喷射用水量，以此节省了单次冲刷过程的用水量，提高了马桶的冲刷效果，使得马桶可达到一级水效。
一些示例性实施例中，如图1所示，马桶的冲刷***还可以包括水泵7(即增压泵)，水泵7的出水端可以与进水口103连通。如图12所示，水泵7可以设置成与马桶的控制模块9电连接并在控制模块9的控制下启停，在控制模块9的控制下，水泵7可以在冲刷过程开始时启动，在冲刷过程结束时停止。
通过控制模块9控制水泵7启动工作，能够同时给洗刷出水口104和喷射出水口105供水。水泵7设置成有足够的流量和扬程，可以根据需要进行选择，由于洗刷和喷射过程都是通过水泵7供水，所以该马桶的冲刷***对自来水的压力无要求，能够减小马桶冲刷时的噪音，并且降低对水箱6的高度要求，有助于实现超薄款水箱。
一些示例性实施例中，如图1和图3所示，马桶的冲刷***还可以包括水箱6，水泵7安装在水箱6的底部或侧部，且水泵7的进水端与水箱6连通，冲刷控制装置安装在水箱6内。可以提前利用水箱6进行蓄水，更加便于洗刷和喷射过程的顺利进行。
一些示例性实施例中，水箱6可以是塑胶水箱或陶瓷马桶自带水箱，本申请实施例对此不作限制。
一些示例性实施例中，如图1和图3所示，水箱6内安装有进水组件8，水可通过进水组件8进入水箱6内。进水组件8可以包括浮筒801，能够控制水箱6内的水量达到预设的高度时停止进水。其中，进水组件8可为传统的进水组件，采用传统的进水组件，能够保证符合自来水管网的安全标准的要求，保证马桶的安全使用。
一些示例性实施例中，如图12所示，喷射开关阀3可以为电动开关阀，喷射开关阀3可以设置成与马桶的控制模块9电连接并在控制模块9的控制下开闭。
马桶可为智能马桶，水泵7的开关、喷射开关阀3的开闭都可以通过控制模块9精准控制，通过控制喷射开关阀3在水泵7开启过程中的某段时间打开，并通过控制喷射开关阀3打开的时间长度，来实现大小档冲水，冲刷的整个过程中水泵7一直是开启状态，洗刷出水口104也一直在出水进行冲刷。通过控制水泵7和喷射开关阀3，可以精准控制冲刷过程的用水量和喷射出水的持续时间，能够保证冲刷的干净度，冲刷效果好并有助于实现一级水效。
一些示例性实施例中，如图4所示，喷射开关阀3可以包括喷射阀驱动件308、喷射阀芯301、喷射阀动部件302和喷射阀定部件303。喷射阀驱动件308设置成与控制模块9电连接并在控制模块9的控制下运动以进行工作。喷射阀驱动件308与喷射阀芯301连接，喷射阀动部件302安装在喷射阀芯301上，喷射阀定部件303安装在喷射出水口105处，且喷射阀动部件302设有遮挡部304，喷射阀定部件303上设有过水孔305。喷射阀芯301设置成可在喷射阀驱动件308的驱动下带动喷射阀动部件302动作，使遮挡部304遮挡过水孔305(如图4和图5所示)，或者使遮挡部304打开过水孔305(如图7和图8所示)，进而实现控制喷射出水口105的开闭。
喷射阀驱动件308可在控制模块9的控制下工作，带动喷射阀芯301运动，喷射阀芯301带动所连接的喷射阀动部件302运动，使位于喷射阀动部件302上的遮挡部304可遮挡喷射阀定部件303上的过水孔305，将过水孔305关闭，进而喷射开关阀3将喷射出水口105关闭，如果是在冲刷过程中，此时仅通过洗刷出水口104出水，对马桶本体5进行小流量(小档位)的洗刷；喷射阀驱动件308还可带动喷射阀芯301及其上的喷射阀动部件302运动，使位于喷射阀动部件302上的遮挡部304可打开喷射阀定部件303上的过水孔305，进而喷射开关阀3将喷射出水口105打开，此时洗刷出水口104和喷射出水口105同时出水，对马桶进行大流量(大档位)的冲刷。
一些示例性实施例中，如图4、图5和图8所示，喷射阀驱动件308可以为旋转驱动件，且与喷射阀芯301的上端连接，喷射阀驱动件308设置成可带动喷射阀芯301进行转动。喷射阀动部件302和喷射阀定部件303分别为喷射阀动片和喷射阀定片，且喷射阀动片和喷射阀定片均为大致圆形的片 状结构，喷射阀动片和喷射阀定片的中心线与喷射阀芯301的旋转中心线共线。

喷射阀驱动件308可带动喷射阀芯301和喷射阀动片转动，使喷射阀动片上的两个遮挡部304分别与两个过水孔305重合，遮挡过水孔305，或者两个遮挡部304分别与两个过水孔305错位设置，以控制过水孔305的开闭，进而控制喷射出水口105的开闭。
在其他示例性实施例中，喷射阀驱动件308可以设置成可带动喷射阀芯301平移运动，以使喷射阀动片上的遮挡部304遮挡过水孔305或打开过水孔305，遮挡部304对过水孔305进行遮挡或打开，以及过水孔的数量、设置位置等可以有多种实现形式，本申请实施例对此不作限制。

一些示例性实施例中，如图4所示，壳体1上可以开设有安装喷射开关阀3的第二安装槽107，喷射阀芯301的一端可以穿过第二安装槽107，并与壳体1外的喷射阀驱动件308连接，喷射阀芯301与第二安装槽107之间可以设有安装槽密封件310。
一些示例性实施例中，如图4所示，防虹吸阀2可以设置为可溢流的防虹吸阀，壳体1上可以开设有进气口108，防虹吸阀2可以设置成打开进水口103时关闭进气口108，关闭进水口103时打开进气口108。
如图1和图4所示，在马桶处于初始状态(非冲刷状态)时，水泵7关闭，防虹吸阀2将进水口103关闭，同时将进气口108打开，防止水箱6内 的水被虹吸走，当水箱6内的水超过预设的高度时，水可以从进气口108进入壳体1内，并从洗刷出水口104流走，实现溢流效果。如图6、图7和图9所示，在马桶处于冲刷状态时，水泵7打开，防虹吸阀2可在进入进水口103的水的压力作用下打开进水口103，同时关闭进气口108，以便为洗刷出水口104和喷射出水口105供水。
一些示例性实施例中，如图4所示，防虹吸阀2包括可运动的防虹吸阀芯201和防虹吸密封件202，壳体1的上部开设有第一安装槽106，防虹吸阀芯201的上端穿过第一安装槽106，进水口103设在壳体1的下部。防虹吸密封件202安装在防虹吸阀芯201上，防虹吸阀芯201设置成可带动防虹吸密封件202运动，以将进水口103密封关闭(如图1和图4所示)或者打开(如图6、图7和图9所示)。
防虹吸阀芯201可以设置成可在自进水口103进入的水的压力作用下向上移动，以将进水口103打开，还可在自重作用下向下移动，使防虹吸密封件202与进水口103密封抵接，以将进水口103关闭。
一些示例性实施例中，如图4所示，进气口108可以设置在壳体1的上部，且进气口108靠近第一安装槽106设置；可溢流的防虹吸阀2还包括安装在防虹吸阀芯201上、位于防虹吸密封件202上方的进气口密封件204。
如图1和图4所示，当防虹吸阀2在自重作用下将进水口103关闭时，进气口密封件204与进气口108分离，将进气口108打开；如图6、图7和图9所示，当防虹吸阀芯201在水压作用下向上移动时，防虹吸密封件202与进水口103分离，将进水口103打开，且进气口密封件204与进气口108密封抵接，将进气口108关闭。
一些示例性实施例中，如图4所示，防虹吸阀2还可以包括防止水从进气口108喷出的挡水阀盖203，挡水阀盖203位于壳体1外并设置在进气口108的上方。
在水泵7启动，进水口103打开但进气口108还未关闭时，壳体1内的水可能从进气口108喷出，挡水阀盖203的设置可防止水从进气口108喷出。
一些示例性实施例中，如图4所示，洗刷出水口104处可以设有洗刷限流装置4，以控制洗刷出水口104的出水速度。
一些示例性实施例中，如图4所示，壳体1可以包括固定连接的上壳101和下壳102，上壳101和下壳102之间可以设有壳体密封件109。进水口103、洗刷出水口104和喷射出水口105可以设置在下壳102上，进气口108、安装防虹吸阀2的第一安装槽106和安装喷射开关阀3的第二安装槽107可以设置在上壳101上。
如图2所示，本申请实施例还提供了一种马桶，包括马桶本体5，马桶本体5具有洗刷口502和喷射口501。马桶还包括上述马桶的冲刷***，冲刷***的洗刷出水口104与马桶本体5的洗刷口502连通，冲刷***的喷射出水口105与马桶本体5的喷射口501连通。
马桶本体5上还设有排污口503，冲刷后的水从排污口503排出。
下面结合附图说明一些示例性实施例的马桶的冲刷过程。
当水箱6的水进到预设的高度，进水组件8的浮筒801浮起，停止进水，如图1所示，此时进水口103和喷射出水口105均处于关闭状态。水泵7放置在水箱6的底部或侧面，水箱6内有水，水泵7里是灌满水的，能够保证水泵7的正常使用。
如图6所示，冲刷过程开始时，水泵7启动，把水箱6里的水抽出，抽出的水有一定压力，能够把防虹吸阀芯201向上顶，进气口密封件204封住进气口108，这样水就可由进水口103进入壳体1内，洗刷出水口104是常开状态，这时可对马桶本体5的胆包面进行洗刷。为了控制洗刷用水量，可在洗刷出水口104处增加洗刷限流装置4。
如图7所示，当洗刷一定时间T1后，喷射开关阀3动作，打开喷射出水口105，使得水泵7抽出的水大部分流向喷射出水口105，对马桶本体5的胆包进行喷射。
如图9所示，当喷射一定时间T2后，喷射开关阀3关闭，喷射结束，但水泵7还是开启状态，利用洗刷出水口104出水继续进行洗刷。
如图10所示，当再洗刷一定时间T3后，水泵7关闭，洗刷结束，整个冲刷过程结束。此时，防虹吸阀2在自重作用下将进水口103关闭，水箱6内的水位降低，进水组件8的浮筒801下沉，进水组件8开始对水箱6进水。 当水箱6内的进水到预设的高度，浮筒801升起，进水结束，马桶恢复图1所示的状态，可以进行下一次冲刷过程。
如图11所示，马桶冲刷过程中，水泵7开启时间为T1+T2+T3，洗刷过程的时间为T1+T2+T3，喷射过程在中间的T2时间段进行。即，冲刷过程中，水泵7一直处于开启状态，洗刷过程一直进行，在中间一段时间内，进行喷射过程，此段时间内喷射和洗刷过程同时进行。
虽然本申请所揭露的实施方式如上，但所述的内容仅为便于理解本申请而采用的实施方式，并非用以限定本申请。任何本申请所属领域内的技术人员，在不脱离本申请所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本申请的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
