附图说明
图1是本发明实施例中马桶的加热控制流程示意图；
图2是本发明实施例中马桶的控制系统方框图；
图3是本发明实施例中马桶的立体分解示意图。
具体实施方式
以下将结合附图所示的各实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所 做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。例如，如果将图中的设备翻转，则被描述为位于其他单元或特征“下方”或“之下”的单元将位于其他单元或特征“上方”。因此，示例性术语“下方”可以囊括上方和下方这两种方位。设备可以以其他方式被定向(旋转90度或其他朝向)，并相应地解释本文使用的与空间相关的描述语。
并且，应当理解的是尽管术语第一、第二等在本文中可以被用于描述各种元件或结构，但是这些被描述对象不应受到这些术语的限制。这些术语仅用于将这些描述对象彼此区分开。
本发明实施例提供了一种马桶的控制方法以及马桶，如图1所示，马桶的控制方法，包括以下步骤：
S1、控制测距雷达在预设的第一距离范围进行检测；
S2、检测到人体时控制便盖打开，切换测距雷达在预设的第二距离范围进行检测，其中第二距离范围小于第一距离范围；
S3、再次检测到人体时启动石墨烯加热组件开始加热；
S4、检测到人体离开马桶，关闭石墨烯加热组件，切换测距雷达在预设的第一距离范围进行检测。
通过测距雷达在两个预设距离范围进行检测切换，防止有时候只是打扫卫生或者因为靠的近而触发石墨烯加热组件的加热，避免了不必要的能源浪费。
具体的，测距雷达可以通过出厂时预设两个距离范围来切换，当然用户也可以通过马桶的遥控器或APP自行修改合适的距离范围。本实施例中，第一距离范围在80cm到200cm之间，第二距离范围为小于80cm，这样用户进入卫生间就可以被感测到，就可以进行相应的控制以为用户 如厕提前准备，而且只有在真正如厕时才控制座圈加热，避免了能源浪费。
上述步骤S2中，检测到人体时控制便盖打开，因便盖打开需要一定的时间，在预设的第一距离范围检测到人体即打开便盖，保证了用户如厕时便盖已完全打开，提升用户体验。接下来进行切换测距雷达的测距范围，当然便盖打开和测距范围切换也可以同时，或者先切换测距范围再打开便盖，只要不影响用户如厕即可。
上述步骤S3中，从再次检测到人体的皮肤接触到座圈，还有一些时间，而石墨烯组件的加热速度非常快，也就是说，人体接触到座圈时，石墨烯组件已经加热2S-3S，此时座圈通过温度传感器已经将温度控制在预设温度范围，从而实现即热方法的控制。
本实施例中优选的，测距雷达在预设的第一距离范围检测到人体时开始计时，到测距雷达在预设的第二距离范围检测到人体时的时间间隔小于第一预设时间才启动石墨烯加热组件开始加热。这样能够进一步防止非如厕时启动石墨烯加热组件，也就是说，通过测距雷达和时间计算双重保险，因为打扫卫生时间会较长，而如厕时从进入卫生间到靠近马桶时间不会长，这样加如果长时间测距雷达在预设的第二距离范围没有检测到人体，石墨烯组件就不会启动加热。进一步的，可以在再次检测到人体时的时间间隔大于第一预设时间时控制便盖关闭，以防止异味散发。
另外，因为男女如厕不同，男士小便不需要接触座圈，可以在第二预设时间内未检测到人体着座信号，则控制座圈打开，关闭石墨烯加热组件。也就是说，测距雷达在预设的第二距离范围进行检测时，在第二预设时间并没有检测到人体着座的信号，默认为男士小便，从而控制座圈自动打开，手不需要接触座圈底部去掀起座圈，更方便卫生。另外，考虑到长时间坐在座圈的情况，只要检测到人体着座信号，控制石墨烯加热组件的加热时间间隔，并检测座圈的温度，使座圈的温度保持在预 设的温度范围。提升用户使用的舒适感。
进一步的，上述步骤S4中，检测到人体离开马桶，关闭石墨烯加热组件，切换测距雷达在预设的第一距离范围进行检测，方便下一次的使用。其中检测到人体离开马桶的方法包括人体着座信号消失或者测距雷达在预设的第一距离范围未检测到人体，也就是说，再检测到着座信号一定时间后没有了着座信号，即用户如厕完毕；而测距雷达在预设的第一距离范围未检测到人体，即用户离开卫生间。
基于上述控制方法，本发明还涉及一种马桶，参照图2和3所示，马桶包括马桶桶体10、固定连接于马桶桶体10上的主体20以及均枢转连接于20主体两侧的便盖30和座圈，主体20上安装有驱动便盖30和座圈枢转的驱动装置以及连接驱动装置的控制器50，驱动装置可以安装在主体20内，具体的可以包括电机以及由电机带动的齿轮机构，其中主体20可以安装在底座21上，底座21直接固定于马桶桶体10，控制器50和驱动装置都可以安装在主体20和底座21之间，这样方便马桶的安装。
座圈包括座圈上盖41、座圈下盖42以及设置在之间的石墨烯加热组件43，石墨烯加热组件43包括石墨烯层，石墨烯层形状配合的贴覆于座圈上盖41的内侧。主体20上还安装有连接控制器50的测距雷达60，控制器50基于测距雷达60的检测信号控制测距雷达60在预设的第一距离范围和预设的第二距离范围进行切换，其中第二距离范围小于第一距离范围，测距雷达60在预设的第一距离范围检测到人体时，控制器50控制控制便盖30枢转打开并切换测距雷达60在预设的第二距离范围检测，测距雷达60在预设的第二距离范围检测到人体时，控制器50启动石墨烯加热组件开始加热。
进一步的，控制器包括PCBA板51以及连接到PCBA板51上的计时器52，计时器52用于记录从测距雷达60在预设的第一距离范围检测到人体到在预设的第二距离范围检测到人体时的时间间隔。
座圈上设有着座感应器45，着座感应器45可以是压力传感器或者其它可以感测到人体与座圈接触的传感器，着座感应器45与控制器50连接，控制器50根据着座感应器45的检测信号对座圈和/或石墨烯加热组件43进行相应的控制。如在预设的第二距离范围检测到人体但是在第二预设时间内未检测到人体着座信号，控制座圈打开，关闭石墨烯加热组件43；或者检测到人体着座信号，控制石墨烯加热组件43的加热时间间隔；或者检测到人体着座信号后一定时间内人体着座信号消失，关闭石墨烯加热组件43等等。
座圈上还设有温度传感器53，温度传感器53用于检测座圈的温度，控制器50根据检测到的温度控制石墨烯加热组件43的加热时间，以使座圈温度保持在一个使用户感觉舒适的预设温度范围内。
进一步的，石墨烯层与座圈下盖42之间设有隔热层，隔热层构造EPE隔热膜，防止热量向座圈的底部传递，避免热量流失。
上述实施方式中通过测距雷达与石墨烯加热结合可以实现座圈即热，由于石墨烯层具有非常好的热传导性能，使得座圈能够只在用户如厕时保持使人体感到舒适的温度，并且座圈温度均匀，用户体验好。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
