Description

真空辅助便器 本申请要求于 2009年 9月 24日提交的申请号为 200920311288. 9， 发明名称 为 真空辅助便器 的中国专利申请的优先权， 其全文引用在此供参考。
技术领域
本发明涉及一种便器， 尤其一种即能节水又能除臭的真空辅助便器。
背景技术
目前市面上的便器大多采用重力或重力 +虹吸的冲洗方式进行排污。 这两种 方式主要存在耗水量大问题， 即使节水型的便器， 每次冲洗水量也在 7— 8升。 据统计， 冲洗便器用水约占人们日常用水的 40%， 这对我国水资源提出了更加严 峻的考验。
另外， 卫生间异味一直以来困扰着公众， 而卫生间的异味主要是人体排泄物 分解后产生的氨气和含硫物质发出的，如果浓度大了可是会中毒。 传统方法主要 采用通风的方式， 而有些高层建筑的卫生间排气道一般都比较狭窄， 自然通风的 效果差。一旦遇到无风、 逆温天气， 卫生间里的异味很难排到室外， 甚至扩散到 室内， 污染室内空气环境。
以往专利中， 在申请号 98126485. 9、 01241556. 1和 200620138598, ί中分 别提到了座便器的除臭方法及装置，但仅仅提到了如何达到除臭的方法。在申请 号 95193959. 9中， 提到了一种包含喷射器的真空装置及包含此装置的真空便器 系统。但该装置必须需要独立的压縮气源作为喷射器的工作介质来使其吸气箱产 生真空， 这就严格限制了使用环境和条件。
发明内容
本发明为克服上述现有技术的不足，提供一种真空辅助便器， 利用排风扇从 产生卫生间异味的根源排除异味，同时利用排风扇的排风口处的气体作为气体喷 射器的工作介质， 使排污管路内产生一定的负压， 在冲洗水压、污物重力及辅助 负压的三者共同作用下进行排污，从而达到减少便器冲洗用水量和卫生间气味的 目的。
为实现上述目的， 本发明采用如下技术方案：
1.一种真空辅助便器， 它包括便斗、 除味管路、 冲洗管路以及感应开关， 其 中， 便斗的冲洗口与除味管路连通， 除味管路与真空装置连接； 便斗内设有存水 弯 I、 存水弯 I I和排污口， 冲洗管路分别与便斗的冲洗口和存水弯 I I连接； 感应 开关控制与控制装置连接， 控制装置控制除味管路和冲洗管路。 2.便斗包括存水弯 I、 存水弯 I I和排污口。 存水弯 I和存水弯 I I用来保证在 便斗排污管路内部形成封闭的一段空间， 便于真空的形成。
3.除味管路有排风管路和真空管路组成，排风管路与冲洗口连接， 其上依次 设有止回阀、排风扇、喷射器，喷射器与排气管路连接；真空管路包括真空储罐， 真空储罐与冲洗口连接侧设有阀 I I， 另一侧与喷射器连接并设有阀 I。
4.冲洗管路分为冲水管路和抽气冲洗管路， 它们均与水管连接， 其中冲水管 路通过阀 IV与存水弯 I I连接， 抽气冲洗管路则通过阀 I I I与冲洗口连接。
本发明的便器由便斗、 排风管路、 冲水管路、 感应开关及控制元件等组成。 便斗组成为存水弯 I、 存水弯 I I、 排污口。 排风管路组成为止回阀 I I、 排风扇、 排风管路、 喷射器、 排气管路、 阀 I、 真空储罐、 真空管路、 阀 I I、 抽气冲洗管 路， 冲水管路组成为阀 I I I、 阀 IV、 冲洗管路。
工作过程为：
1、 感应开关感应到人如厕时， 排风扇开始工作， 驱动喷射器工作。 两者工 作后一方面排风扇通过便斗内的冲洗口对人排放的污物散发的异味进行 抽吸， 经喷射器出口和排气管路排到建筑中的排风道中； 另一方面两者 工作的同时阔 I打开， 真空储罐和真空管路中在喷射器的工作下建立了 一定的真空。 具体工作状态参见图 2。
2、 当感应开关感应到人离开后， 阔 I关闭， 阀 II和阔 III打开， 便斗进行 正常冲洗的同时， 排污管路内由于真空和重力的双重作用通过排污口进 行排污。 具体工作状态参见图 3。
3、 便斗进行完冲洗和排污后， 除了阔 IV打开， 其他阀全部关闭。此时经冲 洗管路对存水弯 II处进行冲洗： 一是防止污物在此处有堆积现象， 影响 下一次便斗排污效果。 二是有效的保证了此处水封质量， 保证在排污管 路中形成一段密闭空间， 为下一个冲洗循环做准备。 具体工作状态参见 图 4。
本发明的有益效果是： 利用排风扇直接驱动喷射器工作， 不仅原理和结构简 单， 使用方便， 而且克服了传统便器只靠重力或者重力 +虹吸的排水方式的用水 量大的问题， 同时克服了人如厕时卫生间异味大等缺点。 实现了冲洗用水量少， 卫生间异味小， 改善了卫生间环境， 该便器对排污的重力管路无特殊要求， 无论 应用在新建或改造等场合都能满足使用要求。 附图说明

具体实施方式
下面结合附图与实施例对本发明做进一步说明。
图 1、 图 2、 图 3、 图 4中， 它包括便斗、 除味管路、 冲洗管路以及感应开 关 4， 其中， 便斗的冲洗口与除味管路连通， 除味管路与真空装置连接； 便斗内 设有存水弯 11 .1、存水弯 111 .2和排污口 1 .3，冲洗管路分别与便斗的冲洗口和存 水弯 111 .2连接； 感应开关 4控制与控制装置连接， 控制装置控制除味管路和冲 洗管路。
除味管路有排风管路 2.3和真空管路 2.8组成，排风管路 2.3与冲洗口连接， 其上依次设有止回阀 2.1、 排风扇 2.2、 喷射器 2.4， 喷射器 2.4与排气管路 2.5 连接;真空管路 2.8包括真空储罐 2.7，真空储罐 2.7与冲洗口连接侧设有阀 I I2.9, 另一侧与喷射器 2.4连接并设有阀 12.6。
冲洗管路分为冲水管路 3.3和抽气冲洗管路 2.1 0， 它们均与水管 3.4连接， 其中冲水管路 3.3通过阀 IV3.2与存水弯 111 .2连接， 抽气冲洗管路 2.1 0则通过 阀 1113.1与冲洗口连接。
本发明中采用了辅助的真空进行冲洗，达到减少冲洗用水量和卫生间气味的 目的。利用卫生间内的排气扇的排风口处的气体作为工作介质驱动喷射器在排污 管路产生真空，利用排气扇通过便斗内部的冲洗口来排放人如厕时产生的污物散 发的气味。便斗内部有两个存水弯， 在排污管路内部形成一个密闭空间， 便于产 生真空。 除味管路主要由排风扇、 喷射器、 真空储罐及电磁阀和单向阀组成， 用 来实现使排污管路产生真空和排放卫生间异味的双重作用。冲水管路有两部分组 成，一部分提供便斗正常冲洗所需用水；另一部分提供对另一个存水弯进行冲洗， 防止污物在此处产生堆积。
虽然本发明参照优选实例作了如上说明，但还要了解， 在权利要求的范围内 可以做一些改动。例如感应开关 4可以换成其他的感应方式， 来产生触发信号达 到同样的使用效果。
