一氧化碳检测联动控制系统和控制方法
本公开要求于2019年10月11日提交中国专利局、申请号为201910961583.7、发明名称为“一氧化碳检测联动控制系统和控制方法”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及滑动驱动结构以及气体检测和控制技术，尤其涉及一种一氧化碳检测联动控制系统和控制方法。
背景技术
对于消费者来说，燃气热水器的安全、环保是个极其重要的指标，市面上的燃气热水器影响安全、环保主要体现在热水器在燃烧时，燃气与空气混合比例控制相对模糊，燃气与空气混合不均，一氧化碳及氮化物排放不能很好控制，浪费燃气。
造成以上原因主要是燃气热水器在燃烧时，主要通过调节风机的空气流量来调节燃气与空气的供给配比，而分段燃烧时只有部分火排燃烧，而空气的进入口大小未变导致无论如何调整风机风量，总有一部分空气通过未燃烧的火排区域，不但未能与燃烧的燃气混合参与燃烧，为控制总流量，易导致燃气空气混合不足；还在流通过程中，带走了燃气的热量，降低燃烧效率，也容易出现燃气空气混合不足从而出现一氧化碳超标。
发明内容
本公开要解决的技术问题是提供一种一氧化碳检测联动控制系统和控制方法，解决了多余空气供给带走燃烧火焰热量以及为控制空气总流量而空气补充不充分从而造成一氧化碳超标的问题。
为解决上述技术问题，本公开采用如下技术方案：
一方面，本公开提出一种一氧化碳检测联动控制系统。所述一氧化碳检测联动控制系统包括空气进口调节装置、一氧化碳检测仪和主控器，其中，空气进口调节装置包括盖板、滑轨、以及滑动驱动机构，受到滑动驱动机构的驱动作用时盖板沿着滑轨滑动；一氧化碳检测仪和滑动驱动机构都与主控器连接。
在一些实施方式中，对于所述一氧化碳检测联动控制系统，滑动驱动机构包括旋转轴，盖板上设有平行于其滑动方向延伸的滑齿，旋转轴上套置圆齿轮，圆齿轮能够与盖板上的滑齿咬合以通过旋转轴旋转带动盖板沿滑轨滑动。
在一些实施方式中，对于所述一氧化碳检测联动控制系统，滑动驱动机构还包括驱动电磁阀，旋转轴与驱动电磁阀连接，驱动电磁阀与主控器连接。
在一些实施方式中，对于所述一氧化碳检测联动控制系统，旋转轴与驱动电磁阀上的旋转套套接，当驱动电磁阀工作旋转时，带动旋转轴转动。
在一些实施方式中，对于所述一氧化碳检测联动控制系统，盖板在空气进口处的边缘设有沿着边缘排列的锯齿。
在一些实施方式中，对于所述一氧化碳检测联动控制系统，盖板与设有锯齿的边缘垂直的边缘设有滑轴，滑轨包括滑槽，滑轴装在滑轨的滑槽内。
另一方面，本公开提出一种上述一氧化碳检测联动控制系统的控制方法。所述控制方法包括：当燃气热水器工作时，接收一氧化碳检测仪检测到的一氧化碳含量值；将收到的一氧化碳含量值与标准值范围比较；根据比较结果控制空气进入口的大小。
在一些实施方式中，对于所述控制方法，根据比较结果控制空气进入口的大小包括：当收到的一氧化碳含量值在标准值范围内时，保持当前的空气进入口的大小。
在一些实施方式中，对于所述控制方法，根据比较结果控制空气进入口的大小包括：当收到的一氧化碳含量值低于标准值范围的下限值时，减小空气进入口的大小，直到所检测的一氧化碳含量值达到标准值范围内。
在一些实施方式中，对于所述控制方法，根据比较结果控制空气进入口 的大小包括：当收到的一氧化碳含量值高于标准值范围的上限值时，增大空气进入口的大小，直到所检测的一氧化碳含量值达到标准值范围内。
与相关技术相比，本公开技术方案主要的优点如下：
本公开实施例的一氧化碳检测联动控制系统和控制方法通过将补充空气进气口设置成带滑动盖板并可滑动调整大小的方式，滑动盖板受旋转电磁阀驱动，使用电磁阀带动滑动盖板开合移动，形成补充空气进气口不同大小，同步滑动盖板边缘有三角锯齿形结构，在空气流通中形成扰流，增加空气混合能力。同时，此机构与一氧化碳检测仪联动控制，根据检测到的不同一氧化碳含量调整空气进气量，保证进入的空气精准参与燃气混合燃烧，提高燃烧效率，减少一氧化碳及氮化物的排放。
本公开实施例的一氧化碳检测联动控制系统和控制方法将可变补充空气结构与一氧化碳检测仪器联合控制，实现了在不同状态下，通过检测一氧化碳的含量，判断空气与燃气补充比例是否达到最佳混合状态，实现调整空气参与燃烧的进气量更精准，多余空气带走热量的比例更低，同时一氧化碳含量控制更稳定。

图1A和图1B为本公开一个实施例提供的一氧化碳检测联动控制系统的不同视角的结构示意图。如图1A和图1B所示，本公开一个实施例提供的一氧化碳检测联动控制系统包括空气进口调节装置100、一氧化碳检测仪200和主控器300。其中，空气进口调节装置100包括盖板110、滑轨120、以及滑动驱动机构，受到滑动驱动机构的驱动作用时盖板110沿着滑轨120滑动。一氧化碳检测仪200和滑动驱动机构都与主控器300相连接。一氧化碳检测仪200实时将信号传输给主控器300，同时主控器300根据程序控制滑动驱动机构。
图2A、图2B和图2C分别为图1A中所示的盖板、滑轨和旋转轴的结构示意图。图3为图1A中所示的旋转轴与驱动电磁阀的连接示意图。如图2A、图2B和图2C所示并如图3所示，滑动驱动机构可以包括旋转轴131，盖板110上设有平行于其滑动方向延伸的滑齿111，旋转轴131上套置圆齿轮133，圆齿轮133能够与盖板110上的滑齿111咬合以通过旋转轴131旋转带动盖板110沿滑轨120滑动。滑动驱动机构还可以包括驱动电磁阀135，旋转轴131与驱动电磁阀135连接，驱动电磁阀135与主控器300连接。进一步来说，旋转轴131与驱动电磁阀135上的旋转套137套接，当驱动电磁阀135工作旋转时，带动旋转轴131转动。

盖板110可以在与设有锯齿的边缘垂直的边缘设有滑轴115，滑轨120可以包括滑槽121，滑轴115装在滑轨120的滑槽121内。
当需要调整盖板110开合时，驱动电磁阀135带动旋转轴131旋转，旋转轴131上的圆齿轮133与盖板110上的滑齿111咬合，驱动盖板110滑动，因为盖板110上的滑轴115套在滑轨120的滑槽121内，盖板110顺着滑轨120实现线性开合。
如图1B所示，燃气热水器包括燃烧器组件400、风机500和一氧化碳检测仪200。其中，一氧化碳检测仪200与风机500通过导气管600相通，一氧化碳检测仪200检测风机500排出废气里面的一氧化碳含量。
图4为本公开另一个实施例提供的上述一氧化碳检测联动控制系统的控制方法的流程图。
如图4所示，在步骤S410，当燃气热水器工作时，接收一氧化碳检测仪200检测到的一氧化碳含量值。
在步骤S420，将收到的一氧化碳含量值与标准值范围比较。
在步骤S430，根据比较结果控制空气进入口的大小。
步骤S430的具体过程可以包括：如果收到的一氧化碳含量值在标准值范围内，则控制驱动电磁阀135停留在当前位置以保持当前的空气进入口的大小。如果收到的一氧化碳含量值低于标准值范围的下限值，则控制驱动电磁阀135朝第一方向旋转以减小空气进入口的大小，直到所检测的一氧化碳含量值达到标准值范围内。如果收到的一氧化碳含量值高于标准值范围的上限值，则控制驱动电磁阀135朝与第一方向相反的第二方向旋转以增大空气进入口的大小，直到所检测的一氧化碳含量值达到标准值范围内。
图5A、图5B和图5C分别为图1A所示的一氧化碳检测联动控制系统的空气进口调节装置保持盖板打开状态、缩小盖板打开状态、以及增大盖板打开状态的结构示意图。如图5A所示，当燃气热水器工作时，当一氧化碳检测仪200检测到一氧化碳含量在标准值范围内时，驱动电磁阀135保持盖板110在默认位置。如图5B所示，当燃气热水器工作时，当一氧化碳检测仪200检测到一氧化碳含量低于标准值范围时，主控器300判定为富氧燃烧，空气补充过量，则控制驱动电磁阀135朝第一方向旋转，减少盖板110打开距离，直到一氧化碳含量达到标准值范围内。如图5C所示，当燃气热水器 工作时，当一氧化碳检测仪200检测到一氧化碳含量高于标准值范围时，主控器300判定为低氧燃烧，空气补充不足，则控制驱动电磁阀135朝与第一方向相反的第二方向旋转，增大盖板110打开距离，直到一氧化碳含量达到标准值范围内。
本公开实施例的一氧化碳检测联动控制系统和控制方法通过将补充空气进气口设置成带滑动盖板并可滑动调整大小的方式，滑动盖板受旋转电磁阀驱动，使用电磁阀带动滑动盖板开合移动，形成补充空气进气口不同大小，同步滑动盖板边缘有三角锯齿形结构，在空气流通中形成扰流，增加空气混合能力。同时，此机构与一氧化碳检测仪联动控制，根据检测到的不同一氧化碳含量调整空气进气量，保证进入的空气精准参与燃气混合燃烧，提高燃烧效率，减少一氧化碳及氮化物的排放。
本公开实施例的一氧化碳检测联动控制系统和控制方法将可变补充空气结构与一氧化碳检测仪器联合控制，实现了在不同状态下，通过检测一氧化碳的含量，判断空气与燃气补充比例是否达到最佳混合状态，实现调整空气参与燃烧的进气量更精准，多余空气带走热量的比例更低，同时一氧化碳含量控制更稳定。
本公开实施例的优点是相对现有非可变补充空气进口，补充空气只从被点燃的火排补充空气混合，在保证空气、燃气有效混合的前提下，同时避免了多余冷空气带走燃气热量，能更稳定地控制燃烧状态，控制一氧化碳及氮化物的生成，安全、节能、环保。
以上所述仅为本公开的实施例，并非因此限制本公开的权利要求保护范围，凡是利用本公开说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本公开权利要求的保护范围内。
