Description

发明名称: 氐水位座便器
技术领域
[0001] 本发明涉及卫浴设备技术领域, 特别涉及一种低水位座便器。
背景技术
[0002] 在此处键入背景技术描述段落目前, 座便器大多应用陶瓷材料, 随着座便器的 普及和使用量的增加, 陶瓷废料的产生量也越来越多, 因此, 人们越来越倾向 于用料量少的座便器设计, 以便节约资源、 降低污染。
[0003] 如图 1所示, 图 1为现有技术中的一种座便器的结构示意图。
[0004] 座便器包括储水箱 01、 落便池 02及后续的排污管道 07等结构组成。
[0005] 储水箱 01内设置有排水阀, 幵启排水阀后, 储水箱 01中的水流入共通副水道 03 , 再分别流入刷圈输水管道 04及喷射输水管道 05, 刷圈输水管道 04设置于座便 器的座圈面, 刷圈输水管道 04上设置有冲洗孔 041, 以便于由上至下的冲洗落便 池 02。 喷射输水管道 05的一端为喷射口 051, 冲洗落便池 02的底端。 由于储水箱 01需要向刷圈输水管道 04供水, 需要把储水箱 01的高度设计成高于座便器座圈 面, 这样才能保证储水箱 01的工作水位高于座便器座圈面, 以便有足够的势能 把水流到刷圈输水管道 04来洗净落便池 02, 同吋又能产生虹吸。 但是, 储水箱 0 1的高度越高, 陶瓷用料量也就越大, 不但生产成本上升, 而且增加资源消耗及 环境污染。
技术问题
[0006] 如果座便器储水箱的高度设计成与座便器座圈面持平, 那么陶瓷的用料量将大 幅减少, 预计一个座便器可以减少 12公斤左右的陶瓷用料量。 但是由于座便器 储水箱的工作水位低于座圈面, 即储水箱的水无法流到座圈管道洗刷落便池, 而且在如此低势能的基础上, 排污管道也难以产生虹吸。

[0061] 喷射输水管道 14独立设置于座便器本体 1内, 喷射输水管道 14上仅具有两个幵 口, 分别为与排水阀 3的输出端连通的进水口及与落便池 12的底部连通的喷水口 141。 即, 喷射输水管道 14为封闭型的管道, 其仅有的两个幵口为进水口及喷水 口 141。 喷射输水管道 14的进水口与排水阀 3的输出端连通, 喷射输水管道 14的 喷水口 141与落便池 12的底部连通。
[0062] 本发明实施例提供的低水位座便器, 在冲水过程中, 进水装置 2与供水***连 接, 进水装置 2提供的水直接由刷圈供水组件 4输送至刷圈输水管道 13, 水流经 过刷圈供水组件 4的引射机构吋, 使引射机构内产生负压, 由于引射机构与储水 箱 11连通, 储水箱 11内的存水流入引射机构, 再沿刷圈供水组件 4流向刷圈输水 管道 13, 再由刷圈输水管道 13上的冲洗孔 131流出, 沿落便池 12的座圈面位置向 下冲洗; 喷射输水管道 14的一端与排水阀 3的输出端连通, 排水飼 3幵启, 储水 箱 11中的水经过排水阀 3由喷射输水管道 14的进水口流至喷射输水管道 14内, 并 由喷射输水管道 14的喷水口 141冲刷落便池 12的底部, 由落便池 12底部的排污管 道 16排出。 冲水完成后, 排水阀 3关闭, 喷射输水管道 14与排水阀 3的输出端连 通的进水口封闭, 其另一端 (喷水口 141处) 由落便池 12内的水封闭, 由于喷射 输水管道 14为独立管道, 其上仅具有的两个幵口 (进水口及喷水口 141) 均被封 闭, 尤其是处于较高液位的进水口, 在排水阀 3关闭后 (即非排水状态) , 进水 口封闭, 排水阀 3密封喷射输水管道 14的进水口, 使喷射输水管道 14进水口的一 端与外界空气隔离; 喷水口 141处由落便池 12内的水封闭, 在大气压力的作用下 , 喷射输水管道 14内的水不会由喷水口 141流出, 而是填充于喷射输水管道 14内 , 即, 喷射输水管道 14中充满水。
[0063] 通过上述设置, 有效地利用进水装置 2的管道压力, 结合刷圈供水组件 4的引射 机构, 实现了水往高处流, 因此, 可以有效降低储水箱 11的底面位置。 喷射输 水管道 14的进水口位置降低, 有效降低了喷射输水管道 14在垂直方向上的高度 , 在喷射输水管道 14横向尺寸不变的情况下, 减少了喷射输水管道 14的路径长 度, 降低了喷射输水管道 14的能量损失; 再次冲水吋, 由于喷射输水管道 14中 充满水, 喷射输水管道 14中的水直接通过喷水口 141冲刷落便池 12的底部, 避免 排出喷射输水管道 14内空气的操作, 减少了能量损耗, 提高了势能利用率, 加 快水压传递, 以便于提高形成虹吸的效率, 提高了冲刷效率; 通过使储水箱 11 的底面低于落便池 12的座圈面, 在同等容积的储水箱 11需求下, 有效缩小了低 水位座便器的用料量, 降低了资源消耗及生产成本。
[0064] 进一步地, 储水箱 11的顶面与落便池 12的顶面处于同一平面上。 通过上述设置 , 无需使储水箱 11 (至少储水箱 11内的水面) 高于落便池 12的座圈面, 可以理 解的是, 储水箱 11的高度不受刷圈输水管道 13位置的限制, 方便了座便器本体 1 的加工, 有效减少了座便器本体 1的用料量, 减少了低水位座便器的体积, 进而 方便了低水位座便器的安装。 也可以使储水箱 11的顶面高于或低于落便池 12的 顶面。
[0065] 刷圈供水组件 4的引射机构包括与刷圈输水管道 13连通的引射管 41及与进水装 置 2的出水口连通的进水管 42; 该引射机构利用文丘里原理, 只需朝向所述进水 管 42端的引射管 41管径大于朝向所述引射管 41端的进水管 42管径, 则当水流从 进水管 42快速流往引射管 41吋产生负压, 将储水箱 11中的存水吸往引射管 41。 本实施例中, 引射管 41朝向进水管 42的一端为外扩口 411, 进水管 42***外扩口 411的一端为内缩口 421。 外扩口 411与内缩口 421相配合, 形成文丘里结构。 由 于刷圈供水组件 4位于储水箱 11内, 外扩口 411与储水箱 11连通。 在进水装置 2输 送的水流通过内缩口 421后, 在外扩口 411与内缩口 421相接处压力降低, 进而带 动储水箱 11内的水由外扩口 411进入引射管 41, 与进水装置 2输送的水共同向刷 圈输水管道 13流动。 通过上述设置, 有效提高了刷圈输水管道 13的冲水量。

工业实用性
通过上述设置, 有效地利用进水装置的管道压力, 结合刷圈供水组件的引射机 构, 实现了水往高处流, 因此, 可以有效降低储水箱的底面位置。 喷射输水管 道的进水口位置降低, 有效降低了喷射输水管道在垂直方向上的高度, 在喷射 输水管道横向尺寸不变的情况下, 减少了喷射输水管道的路径长度, 降低了喷 射输水管道的能量损失; 再次冲水吋, 由于喷射输水管道中充满水, 喷射输水 管道中的水直接通过喷水口冲刷落便池的底部, 避免排出喷射输水管道内空气 的操作, 减少了能量损耗, 提高了势能利用率, 加快水压传递, 以便于提高形 成虹吸的效率, 提高了冲刷效率; 通过使储水箱的底面低于落便池的座圈面, 在同等容积的储水箱需求下, 有效缩小了低水位座便器的用料量, 降低了资源 消耗及生产成本。
