Description

一种超低喷射虹吸式蹲便器 技术领域
本发明涉及卫生洁具技术领域，尤其涉及一种超低喷射虹吸式蹲便器。
背景技术
带存水弯的蹲便器由于自带存水弯，可以起到隔臭、防虫的效果。
然而，由于带整体存水弯的蹲便器存在坯体厚度、水封深度、通过固体球冲洗试验等要求(其中坯体厚度要求不小于6mm，固体球冲洗试验中的固体球直径要求在41mm以上，水封深度要求不小于50mm)，目前市面上带整体存水弯的蹲便器普遍偏高，其整体高度一般大于260mm。这种带整体存水弯的蹲便器无法适用卫生间沉台较浅的场合，尤其是层楼不高、无法为蹲便器提供足够安装空间的地区，常见如云贵川等地区。

实施本发明，具有如下有益效果：
本发明提供了一种超低喷射虹吸式蹲便器，通过将冲水部成型在胆包本体上，可帮助降低蹲便器的整体高度，结合排污管的结构设计，优化冲水方式和结构，使得蹲便器的整体高度可以达到260mm以下，低于市面上的蹲便器高度，适用于较浅的卫生间沉台使用，同时避免了便池内的污物无法及时冲走、冲水时水流溢出，以及由此造成的溅水问题；
将排污管的进污段与便池下部连通，且缓冲段的底部与进污段连通，冲落段的顶端与缓冲段连通，形成存水弯结构，在冲水时形成虹吸效应，且冲落段的内腔横截面向靠近排污口一端逐渐减小，冲落段在靠近排污口的位置环向设有向内腔隆起的拐角结构，该拐角结构远离所述进污口的隆起高度逐渐增大，且隆起高度最大处与冲落段内壁的夹角为90～135°，即冲落段的横截面在拐角结构位置突然收窄，水流经过拐角结构时水流速度将突然加快，拐角结构的上部空间将瞬时形成负压状态，虹吸效应得到放大，帮助将缓冲段水流快速压至冲落段内；
同时由喷射孔喷出的水能够为经过进污口的污物提供向进污段和缓冲段内流动的动力，加快污物流动，可以提升蹲便器的冲洗力度，冲洗效果好；

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述。
如图1、图2和图3所示，本发明提供了一种超低喷射虹吸式蹲便器的一实施例，包括胆包100和面板200，所述胆包100包括胆包本体1、进水部2和排污管3；所述胆包本体1的顶部开设有便池11，所述便池11的顶部周缘设有冲水部12，所述面板200遮盖所述冲水部12的顶部，其设有伸入所述便池11的挡水环4；所述进水部2与所述胆包本体1连接，所述进水部2与冲水部12连通；所述排污管3与所述胆包本体1连接，所述排污管3包括依次设置的进污段31、缓冲段32和冲落段33，所述进污段31设有与所述便池11下部连通的进污口311，所述进水部2设有与所述进污口311相对设置的喷射孔21；所述缓冲段32的底部与进污段31连通，所述进污段31和缓冲段32内腔的各处横截面形状和大小一致，且所述进污段31和缓冲段32内腔各处横截面的横向宽度大于竖向宽度；所述冲落段33的上部与所述缓冲段32连通，所述冲落段33的底部设有排污口331，所述冲落段33的内腔横截面向靠近所述排污口331一端逐渐减小，且所述冲落段33在靠近所述排污口331的位置环向设有向内腔隆起的拐角结构332，所述拐角结构332远离所述进污口311的隆起高度逐渐增大，且隆起高度最大处与所述冲落段33内壁的夹角a1为90～135°。
本实施例通过将冲水部1212成型在胆包本体11上，可帮助降低蹲便器的整体高度，结合排污管33的结构设计，优化冲水方式和结构，使得蹲便器的整体高度可以达到230～260mm，低于市面上的蹲便器高度，适用于较浅的卫生间沉台使用。
本实施例具体将排污管3的进污段31与便池11下部连通，且缓冲段32的底部与进污段31连通，冲落段33的顶端与缓冲段32连通，形成存水弯结构，在冲水时形成虹吸效应，且冲落段33的内腔横截面向靠近排污口331一端逐渐 减小，冲落段33在靠近排污口331的位置环向设有向内腔隆起的拐角结构332，该拐角结构332远离所述进污口311的隆起高度逐渐增大，且隆起高度最大处与冲落段33内壁的夹角为90～135°，即冲落段33的横截面在拐角结构332位置突然收窄，根据管道横截面与压力的关系，横截面小的位置，其压力较大，水流经过拐角结构332时水流速度将突然加快，拐角结构332的上部空间将瞬时形成负压状态，虹吸效应得到放大，帮助将缓冲段32水流快速压至冲落段33内。
本实施例拐角结构332远离所述进污口311的隆起高度逐渐增大，且隆起高度最大处与所述冲落段33内壁的夹角为90～135°，在通过突然收窄横截面提升虹吸效果的同时，使拐角结构332靠近进污口311一侧与冲落段33内壁相切，或尽可能地平滑过渡，可使污物能够尽可能顺滑地排出。
由喷射孔21喷出的水能够为经过进污口311的污物提供向进污段31和缓冲段32内流动的动力，加快污物流动，可以提升蹲便器的冲洗力度，冲洗效果好。
此外，将进污段31和缓冲段32内腔设计成横截大小和形状一致，使污物能够快速、顺畅地滑过进污段31和缓冲段32，进入冲落段33内；且进污段31和缓冲段32的横截面的横向宽度大于竖向宽度，比同高度圆形横截面的管道截面积更大，排污能力更强，污物随水流得以快速排出，在同等蹲便器高度下的冲水效果更好，能够避免便池11内的污物无法及时冲走、冲水时水流溢出，以及由此造成的溅水问题。
需要说明的是，所述面板200由于不再带有冲水管道，因此可以采用双面注浆成型的方式，成型后的面板200厚度减小至9-15mm，在不影响使用效果的前提下能够帮助缩小蹲便器的整体厚度，节省安装空间。
具体地，本实施例进污段31、缓冲段32和冲落段33的中心轴线处于同一平面，排污管3沿此平面的截面为轴截面。所述进污段31的入口(即进污口311)及出口在轴截面的中点连线与水平线的夹角a2为0～10°，所述缓冲段32的入口和出口在轴截面的中点连线与水平线的夹角a3为38～55°，所述冲落段33的出口(即排污口331)与水平线的夹角为0～10°，所述冲落段入口与出口的夹角为70～100°。所述缓冲段32具体包括第一缓冲段321和第二缓冲段322，所述第一缓冲段321的入口及出口在轴截面的中点连线与水平线的夹角为40～60°，所述 第二缓冲段322的入口和出口在轴截面的中点连线与水平线的夹角为15～40°。进污段31、缓冲段32和冲落段33的设置使蹲便器高度得到压缩，经便池11落入进污段31的污物，经缓慢抬升的缓冲段32进入冲落段33排出。
本实施例的拐角结构332与冲落段33的长度比为1：6～10，拐角结构332的上方空间形成适当大小的负压空间，使冲落段33有足够的空间吸纳由缓冲段32快速压至冲落段33的污物，同时快速经拐角结构332排出。
所述进污段31、缓冲段32内腔各处横截面呈跑道形。排污管3的进污段31、缓冲段32内腔采用跑道形管道截面结构，比同高度圆形管道截面更大，排污能力更强；且在管道截面截面积不变的情况下，有利于提高虹吸力度。
本实施例的所述冲水部12包括导水圈121，结合图4，所述导水圈121内设有与所述进水部22连通的导水腔5，所述导水圈121上间隔预定距离设有与导水腔5相通的布水孔51，该布水孔51优选设置在导水圈121靠近所述进水部22的一侧，实现对便池11的冲刷。所述导水腔5的腔底向靠近所述进水部22一侧朝下倾斜设置。此外，结合图5，所述导水腔5的腔底向靠近所述便池11一侧朝下倾斜设置。所述喷射孔21设于所述进水部22的最低处。由此，冲水结束后，导水腔5内残余的水向靠近便池11一侧聚集，且向进水部22一侧流动，残余的水将全部回流至进水部22。所述喷射孔21优选位于进水部22的最低处，回流至进水部22的水将从位于进水部22最低处的喷射孔21流出，起到补水作用，使作用于冲洗便池11的有效水更多的同时，使导水腔5内、进水部22的空腔内无积水，能够避免积水、藏水、长流水等在长期使用后带来的各类水渍清洁难题，以及在寒冷时节因积水导致腔体冻裂的问题。
此外，本实施例的冲水部12还包括冲水槽122，所述冲水槽122设置在所述导水圈121远离所述进水部22的一侧，所述冲水槽122在便池11侧设有冲水口6，所述导水腔5在所述冲水口6的两侧分别设有对冲孔52。结合图6，所述面板200或所述胆包本体11在所述冲水口6内设有隔水筋板61，所述隔水筋板61将所述冲水槽122从冲水口6处隔断，可以保证冲水过程中各个区间的水流量大致统一，减少冲洗死角；同时可以防止多股水流汇聚撞击形成湍流，减少溅水，提高用户使用体验。需要说明的是，该隔水筋板61也可以直接成型于胆包本体11上。
由此，导水圈121上的布水孔51，与冲水槽122的冲水口6结合形成瀑布 式的冲水方式，布水孔51设于所述导水圈121靠近所述进水部22的一侧，设置冲水口6的冲水槽122设置在所述导水圈121远离所述进水部22的一侧，冲水部12的中部无孔设置，有效控制水流方向与动能，提高便池11冲水效率。
为避免冲水过程中出现溅水现象，结合图7，所述面板200在所述冲水槽122上方设有第一整流部7，所述第一整流部7设有与所述对冲孔52相对设置的弧面凸台71，以及与所述冲水槽122相对设置的压水面72，所述弧面凸台71设于所述压水面72的两侧，所述压水面72与所述冲水槽122的槽底距离沿所述冲水口6的水流方向保持不变。即在冲水口6处形成用于水流平稳流出的等截面空腔。所述冲水槽122在所述对冲孔52与所述冲水口6缘部之间设有第二整流部8，所述第二整流部8与所述弧面凸台71相对设置，且向所述冲水槽122一侧拱起，可以引导从冲水口6流出的水流流动至等截面空腔。所述第二整流部8与所述便池11及冲水槽122槽底圆滑过渡，以减少冲水口6缘部的水流扰动。
所述冲水槽122在所述对冲孔52与所述冲水口6缘部之间设有第二整流部8，所述第二整流部8与所述弧面凸台71相对设置，且向所述冲水槽122一侧拱起，可以引导从冲水口6流出的水流流动至等截面空腔。所述第二整流部8与所述便池11及冲水槽1222槽底圆滑过渡，以减少冲水口6缘部的水流扰动。
当水流冲出对冲孔52时，经第二整流部8引导，经过第一整流部7的弧面凸台71，阻挡水流翻腾，水流进入压水面72与冲水槽122的槽底之间的等截面腔，对水流起到整理效果，减少湍流的产生，逐渐变成平稳流动的状态，水流方向与速度保持一致，有效缓解冲水压力，降低溅水概率，且降低冲水噪音。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
