Description

一种马桶排污结构和马桶 技术领域
本发明涉及家居卫浴领域，尤其涉及一种马桶。
背景技术
市面上的普能马桶具有较长的陶瓷S弯管，而且受陶瓷形成工艺和模具、陶瓷座高限制等影响管径一般都没办法做大(一般都在41-48mm)，所以马桶排污需要较大的势能和水量；这样就造成了现有的马桶冲水需要的水量比较大、水压比较高，产生的噪音也比较大。
发明内容
本发明所要解决的主要技术问题是提供一种马桶排污结构，通过增大排污管的管径，并减短排污管的管长，降低排水的阻力；通过通断阀可以达到排污时，马桶内的水位升高后再排污，具有节水的效果，同时减轻排水的噪声。
为了解决上述的技术问题，本发明提供了一种马桶排污结构，包括缓存室、通断阀以及用于驱动所述通断阀在水封状态和排水状态切换的控制机构；
所述缓存室的进水口与马桶排污管连通，所述缓存室的出水口与排污下水管道连通；所述通断阀设置在缓存室内且位于缓存室出水口处；
所述缓存室内设置有第一液位传感器，马桶冲水时，缓存室内的液面上升，当第一液位传感器检测到液面信号时，所述控制机构控制所述通断阀切换至排水状态；
所述第一液位传感器设置的位置高于未冲水时的水封面。
在一较佳实施例中:所述通断阀的上端设有入水口，通断阀的下端与排污下水管道连通；当所述控制机构控制通断阀处于水封状态时，所述入水口高于未冲水时的水封面；当所述控制机构控制通断阀处于排水状态时，所述入水口低于马桶排污管。
在一较佳实施例中:所述通断阀为弹性伸缩管，所述通断阀由水封状态切换至排水状态时，所述控制机构驱动弹性伸缩管收缩。
在一较佳实施例中:所述缓存室内还设置有第二液位传感器，其所在高度低于第一液位传感器；所述控制机构驱动通断阀由排水状态切换至水封状态时，缓存室内的液面上升，当液面上升至第二液位传感所在的位置时，马桶冲水停止。
在一较佳实施例中:所述通断阀为止水件，所述止水件用于打开或关闭缓存室的出水口。
在一较佳实施例中:还包括一进排气管道，所述排气管道的一端连通缓存室，所述排气管道的另一端连通排污下水管道。
在一较佳实施例中:所述排气管道上还设置有用于控制排气管道通断的电动开关。

本发明还提供了一种马桶，使用了如上所述的马桶排污结构。
在一较佳实施例中:所述马桶排污管的内径大于50mm。
相较于现有技术，本发明的技术方案具备以下有益效果：
本发明提供了一种马桶排污结构，当马桶冲水时，由于通断阀的入水口高于未冲水时的水封面，因此，马桶和缓存室内的液面开始上升，当缓存室内的液面达到第一液位传感器所在的位置时，系统就判定马桶开始冲水了，所述控制机构驱动通断阀打开。当冲水结束后，所述控制机构驱动通断阀进行复位，在马桶和缓存室内重新形成了水封。因此，与现有技术相比，采用这种新的排污方式，可以将马桶排污管的直径扩大，且其直径至少可以为50mm、同时这种排污方式缩短了排污管省去了较大的排污阻力，又充分利用高低水位落差势能进行排污，可以节省用水量和降低噪音降低了排水阻力，减轻了排水噪声。

具体实施方式
下文就本发明的具体实施方法作进一步的说明，但本发明的具体实施方法不限于此。
实施例1
参考图1-7，一种马桶排污结构，包括：缓存室1、通断阀2以及用于驱动通断阀2升降的控制机构3；缓存室1的进水口11与马桶排污管41连通，缓存室1的出水口与与排污下水管道5连通。
所述通断阀2设置在缓存室1内，其下端通过出水口12与排污下 水管道5连通，通断阀2的上端设有入水口21；控制机构3控制通断阀2在最高位置和最低位置之间移动，当控制机构3控制通断阀2升至高位时，入水口高于未冲水时的马桶水封面，如图2所示，这样可以保证马桶4及缓存室1中的水就不会从通断阀2排出，可以保证马桶4内存有正常的水封。当控制机构3控制通断阀2降至低位时，入水口低于马桶排污管41，如图5所示；这样可以保证马桶4及缓存室1中的水和污物可以完全通过通断阀2排出，不会有污物残留。
本实施例中，所述控制机构3包括电机32和控制器31，所述控制器31的信号输入端接收液位信号，信号输出端与控制器31连接。控制器31可以为单片机、MCU或者CPU。在排污时，控制器31输出驱动信号，由电机32带动通断阀2从最高位置向最低位置移动。
因此，本马桶排污结构在工作时，需要在马桶开始冲水时，控制通断阀2下降进入排水状态，以便让马桶4及缓存室1中的水和污物可以通过通断阀2排出。为了达到这样的效果，缓存室1内设置有第一液位传感器13，第一液位传感器13设置的位置高于未冲水时的水封面；当马桶冲水时，由于通断阀2的入水口高于未冲水时的水封面，因此，马桶4及缓存室1内的液面开始上升，当缓存室1内的液面达到第一液位传感器所在的位置时，如图3、7所示，控制器31判定马桶开始冲水了，控制器31进而输出驱动信号驱动电机32带动通断阀2下降，如图4所示。
当冲水结束后，控制器31驱动电机32带动通断阀2上升进行复位，为了让马桶4中重新形成水封。缓存室1内还设置有第二液位传 感器14，其所在高度低于第一液位传感器13；当控制机构3驱动通断阀2上升至最高位置时，通断阀2的入水口21高于马桶排污管41，这样就会使得缓存室1内的液面重新开始上升，当液面上升至第二液位传感14所在的位置时，马桶形成有效的水封，从而实现马桶的水封恢复，此时，整个冲水过程结束，马桶的水箱停止出水，如图6所示。
本实施例中，还包括传动动机构23和导向机构24；所述通断阀组件2为弹性伸缩管21，也可以为波纹管等一切在受到拉力或压力时可以伸缩的管，从而使得通断阀2在受到电机的驱动时可以伸长或者缩短，进而改变入水口与水封面的位置关系。上述通断阀2，由于需要一定运动行程，所以控制机构3与通断阀2之间的传动机构23也需要一定的运动行程，传动机构23与缓存室1之间动态密封；该传动机构23可以是电机通过机械的形式带动通断阀2，从而使得缓存室1连通和断开排污管4；此机械形式可以是齿轮齿条，也可以是拉线加滑轮的形式，但不限于上述的形式。
本实施例中，通断阀2为常开式(气流通道常通)，伸缩管22垂直设置在缓存室1中，弹性伸缩管22上端为入水口21，下端与排污下水管道5密接，常态时，弹性伸缩管22的入水口高于缓存室1的进水口11，缓存室1内壁与弹性伸缩管22外壁之间形成存水空间，缓存室1上方的气体通过弹性伸缩管22排入排污下水管道5；马桶4开始冲水时，缓存室1的液面与马桶4内的液面同步上升，上升至第一液位传感器13所在的位置时，控制器31输出驱动信号电机32工作，通过传动机构23、导向机构24推动伸缩管22压缩下降，至弹性伸缩管22 入水口21的位置位于马桶排污管41之下，充分利用高低水位落差势能进行排污。
实施例2
参考图8-14，本实施例中与实施例1的主要区别在于：本实施例中，所述通断阀为止水件6，所述止水件6用于打开或关闭缓存室2的出水口12。
所述止水件6设置在缓存室1内，缓存室1的入水口与马桶排污管411连通，缓存室1的出水口12和排污下水管道5连通，止水件6用于打开或关闭所述出水口12；如图8所示。
缓存室1内设置有液位传感器15，液位传感器15的位置高于未冲水时的水封面，如图10所示；当马桶4冲水时，缓存室1内的液面上升，当缓存室1内的液面达到液位传感器15所在的位置时，控制机构3驱动止水件6上升，打开缓存室1与排污下水管道5的连通，如图10-12所示。当马桶4冲水结束时，控制机构3驱动止水件6下降关闭缓存室1与排污下水管道5的连通，如图13所示。
本实施例中还包括传动机构62、导向机构63；所述控制机构3包括电机32和控制器31；当马桶4冲水时，缓存室1内的液面上升，当缓存室1内的液面达到液位传感器15所在的位置时，控制器31输出驱动信号电机32工作，通过传动机构62、导向机构63拉动止水件6上升，打开缓存室1与排污下水管道5的连通；当马桶冲水结束时，控制机构3驱动止水件6下降关闭缓存室1与排污下水管道5的通路。
本实施例中还包括一进排气管道7，其一端连通缓存室1上部，另一端连通排污下水管道5，排气管道7中还设置有电动开关阀8。
本实施例中，所述通断阀为常闭式(气体通道常闭)，常态时，止水件6直接封堵在排污下水管道5上方；所述电动开关阀8为常开式，缓存室1内的气体通过进排气管道7进入排污下水管道5。当缓存室1内的液面达到液位传感器15所在的位置时，电动开关阀8闭合，排气管道7关闭。
本实施例中的其余部分与实施例1相同，不再赘述。
上文，仅为本发明较佳的实施范例，不能依此限定本发明实施的范围。即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内.

  3. 根据权利要求2所述的一种马桶排污结构，其特征在于:所述通断阀为弹性伸缩管，所述通断阀由水封状态切换至排水状态时，所述控制机构驱动弹性伸缩管收缩。
  4. 根据权利要求2所述的一种马桶排污结构，其特征在于：所述缓存室内还设置有第二液位传感器，其所在高度低于第一液位传感器；所述控制机构驱动通断阀由排水状态切换至水封状态时，缓存室内的液面上升，当液面上升至第二液位传感所在的位置时，马桶冲水停止。
  5. 根据权利要求3所述的一种马桶排污结构，其特征在于：还包括传动动机构和导向机构；所述控制机构包括电机和控制器；所述弹性伸缩管垂直设置在缓存室内；
    马桶冲水时，缓存室内的液面上升，当第一液位传感器检测到液面信号时，所述控制器驱动电机工作，电机通过传动动机构和导向机构推动伸缩管压缩下降，至伸缩管入水口的位置位于马桶排污管之下，充分利用高低水位落差势能进行排污。
  6. 根据权利要求5所述的一种马桶排污结构，其特征在于：常态时，缓存室内壁与弹性伸缩管外壁之间形成存水空间，缓存室上部气体通过弹性伸缩管排入排污下水管道。
  7. 根据权利要求1所述的一种马桶排污结构，其特征在于：所述通断阀为止水件，所述止水件用于打开或关闭缓存室的出水口。
  8. 根据权利要求7所述的一种马桶排污结构，其特征在于：还包括一进排气管道，所述排气管道的一端连通缓存室，所述排气管道的另一端连通排污下水管道；所述排气管道上还设置有用于控制排气管道通断的电动开关。
  9. 根据权利要求8所述的一种马桶排污结构，其特征在于：常态时，止水件直接封堵在排污下水管道上方；所述电动开关阀为常开式，缓存室内的气体通过进排气管道进入排污下水管道；当马桶冲水时，电动开关阀闭合，排气管道关闭。
  10. 根据权利要求7-9中任一项所述的一种马桶排污结构，其特征在于：所述控制机构包括电机和控制器，所述控制器的信号输入端接 收液位信号，信号输出端与电机连接。
  11. 一种马桶，其特征在于使用了权利要求1-10中任一项所述的马桶排污结构。
