本申请要求2022年01月25日递交的申请号为202220240439.1，发明名称为“一种风道、烟道同轴形式的壁挂炉主动节能保温装置”的中国实用新型专利申请的优先权，其全部内容以引用方式并入本文。
本申请涉及一种风道、烟道同轴形式的燃气(油)取暖(水)壁挂炉，尤其涉及一种可以根据工作需要开启或关闭风道和烟道的主动节能保温装置，杜绝在非燃烧状态下室外冷空气侵入壁挂炉导致热量和燃料损失，保护壁挂炉。尤其是涉及寒冷地区以取暖为主要功能的燃气壁挂炉的主动节能保温。
目前，天然气作为清洁能源使用范围越来越广，燃气壁挂炉的市场占有率也在逐年攀升，这为生态文明建设做出了一定贡献。燃气壁挂炉的进风管道与排烟管道直接通向室外；壁挂炉点火工作时，新鲜空气进入风道，风机将燃烧后的烟气通过烟道强排到室外。然而，这种产品设计存在以下问题和缺点：1.壁挂炉熄火待机时，风机不工作，室外冷空气通过风道和/或烟道侵入壁挂炉。此时在循环水泵的推动下，制暖***的全部热能通过热交换器进行冷热交换，取暖用的壁挂炉热交换器此时变成了散热器，室外温度越低，全***热量损失越严重，浪费了宝贵的热能；2.由于热量损失过快，缩短了保温时间，提高了壁挂炉的点火频次，增加了燃料消耗，浪费了宝贵的能源；3.壁挂炉熄火后为防冻会启动被动防冻功能，即循环水泵一直运行，以***中的全部热量为壁挂炉保温以免发生冻害，这一模式缩短了循环水泵的使用寿命，还浪费了宝贵的电能；4.遇有停电时，循环水泵不工作，如不能及时放水，壁挂炉的热交换器、水泵、管道等会在短时间内被冻坏，给用户带来极大的经济损失；5.目前在产和在用的燃气壁挂炉、大型燃气取暖炉、燃气热水器除部分采用单一烟道的产品带有简易的防冷风倒灌装置外，进风与排烟同轴的双层管道多采用本***热水循环、辅助电加热和启动燃烧加热等被动防冻手段，都没有主动防冷风倒灌装置。其有效的防冻前提是壁挂炉必须通电和通气，如果停电和/或停气，就只剩放水一种保护方法了，对于无人值守的壁挂炉极其危险。
发明内容
为了解决上述问题，本申请提供了一种风道、烟道同轴形式的壁挂炉主动节能保温装置。其目的在于，根据壁挂炉的工作状态主动控制风道、烟道的开启或关闭。即壁挂炉点火工作时，风道和烟道同时打开并在加热的全过程中保证进风和排烟顺畅。壁挂炉熄火后，风道和烟道同时关闭，在下次点火前杜绝冷空气侵入炉内，实现节能保温目的。
为实现上述目的，本申请提供的主动保温节能技术属于一种风道、烟道同轴形式的壁挂炉主动节能保温装置，所述保温装置设有开关电路、驱动器、风道烟道蝶阀和驱动器执行机构；开关电路根据壁挂炉工作状态确定是否为驱动器供电，驱动器执行机构控制风道烟道的开启或关闭，实现主动节能保温，有三种实现形式：1.风道、烟道平行轴控制形式，设有开关电路、驱动器、风道烟道蝶阀和驱动器执行机构；2.风道、烟道同轴控制形式，设有开关电路、驱动器、固定段风道烟道、风道固定隔板、烟道固定隔板、旋转段风道烟道、风道旋转隔板、烟道旋转隔板和驱动器执行机构；3.风道、烟道混合控制形式，设有开关电路、驱动器、烟道蝶阀、风道密封板和驱动器执行机构；三种实现形式所用驱动器都具有断电自动回位关闭风道、烟道的功能。
一种风道、烟道同轴形式的壁挂炉主动节能保温装置，具体是这样实现的：
1.本申请由电信号或风压信号传感器、开关电路、驱动器、阀门、风道、烟道等组成；2.根据壁挂炉的工作状态，传感器提取电信号或者风压信号作为本申请的启动或停止命令，电信号、风压信号二者选一；3.壁挂炉点火工作时有电信号或者风压信号输出，则开关电路闭合为驱动器供电，驱动器执行机构打开风道和烟道阀门，壁挂炉正常工作。壁挂炉熄火后电信号或风压信号消失，开关电路断开，驱动器断电，驱动器执行机构回位，关闭风道和烟道阀门。
在另一个方面中，由于本申请在壁挂炉不点火工作时有效杜绝了冷空气的侵入，可以改原壁挂炉被动保温功能的循环水泵长时间运行为主动保温过程中的间歇工作，能有效延长水泵使用寿命，此外还可以省掉一些机型的电加热部分，从而降低制造成本，节省电能，杜绝冻害，在相同技术参数下相比于目前壁挂炉能有效减少燃料消耗，达到节能、保温、环保的目的。
由于本申请采用非工作时间阻断冷空气侵入的结构，可以得到以下效果：1.将目前壁挂炉点火时呈供热状态，熄火后成为散热窗口的对立工作模式，改变为点火时呈供热
状态，熄火后呈主动保温状态的健康工作模式，有效减少了热量损失；2.在室外温度相同的情况下，本申请的使用降低了壁挂炉的点火频次，节能效果明显，对比数据显示同等条件下节省天然气消耗超过20％；3.本申请杜绝了冷空气从风道、烟道的侵入，同等条件下可以有效延长保温时间，室外温度越低，保温效果越明显；4.本申请采用主动保温模式，可以取消现有产品被动保温的电加热装置，降低制造成本；5.本申请的保温不是靠全***的热量来实现的，可以改现有产品循环水泵长时间运行为间歇运行，能够有效提高循环水泵使用寿命，节省电能；6.由于本申请驱动器有电工作，断电回位的特性决定了不论什么时候停电，驱动器都能安全有效地关闭风道和烟道，从而真正实现主动节能保温功能。

以下结合附图对本申请做进一步详细描述。
本申请的优选实施方式是将传统风道2在外、烟道3在内的同轴形式改为管状平行风道23与管状平行烟道33的平行轴形式，如图1所示，该图1所示的机械结构由驱动器1、管状平行风道23、管状平行烟道33、驱动器轴4、风道蝶阀5、烟道蝶阀6、风道2、烟道3等组成。在装置两端将管状平行风道23和管状平行烟道33的平行轴形式改为同轴形式，以与风道2和烟道3由设计尺寸保证顺序插接、固定并保证正常工作要求。驱动器1固定在管状平行烟道33外表面，驱动器1上装有驱动器轴4，驱动器轴4垂直穿过管状平行烟道33和管状平行风道23的平行段，并做好驱动器轴4与管状平行烟道33和管状平行风道23的平行段之间的密封，驱动器轴4在管状平行风道23和管状平行烟道33内分别固定有风道蝶阀5和烟道蝶阀6。风道蝶阀5与烟道蝶阀6为同轴结构，由驱动器轴4同步驱动，风道蝶阀5和烟道蝶阀6均装有硅胶边以保证密封效果，风道蝶阀5和烟道蝶阀6为常闭状态。
当壁挂炉准备工作时，风机启动，电信号或风压信号使开关电路闭合为驱动器1供电，驱动器轴4带动风道蝶阀5和烟道蝶阀6顺时针旋转，从而打开蝶阀使通风和排烟顺畅，使壁挂炉正常工作。当壁挂炉熄火后，风机停止工作，电信号或风压信号消失，开关电路断开，驱动器1断电，驱动器轴4带动风道蝶阀5和烟道蝶阀6逆时针同步旋转，风道蝶阀5和烟道蝶阀6分别将管状平行风道23和管状平行烟道33封死，从而杜绝冷空气侵入壁挂炉内，实现了节能保温目的。
本申请的另一优选方式是风道与烟道同轴形式，烟道在内，风道在外，如图2和图4所示，该图2和图4示出的机械结构由固定段8(左右两段)、旋转段9、驱动器10、蜗杆15、蜗齿16、风道固定隔板11、烟道固定隔板12、风道旋转隔板13、烟道旋转隔板14等组成。固定隔板、旋转隔板成对设置，可以是各一片或多片，片数不同，安装夹角不同，旋转段工作时旋转角度也不同。隔板的非接触面装有导流鳍。本文以各四片说明。固定段8与旋转段9为管状平行风道23在外和管状平行烟道33在内的同轴管，同段内管状平行风道23和管状平行烟道33相对固定。固定段8的左右两段与旋转段9相互插接，旋转段9在固定段8的左段和右段之间，形成三明治结构。驱动器10分别固定在固定段8的左右两段上并与固定段8的左右两段成为一体，旋转段9在中间可以灵活转动。蜗杆(齿轮)15与蜗齿(齿条)16由安装尺寸保证有效啮合。
图4是图2的A-A剖视图。固定段风道和固定段烟道内分别安装有风道固定隔板11和烟道固定隔板12；旋转段风道和旋转段烟道内分别安装有风道旋转隔板13和烟道旋转隔板14；风道固定隔板11共四片，按90度夹角均匀分布。烟道固定隔板12共四片，按90度夹角均匀分布。风道旋转隔板13共四片，按90度夹角均匀分布。烟道旋转隔板14共四片，按90度夹角均匀分布。安装到位时，旋转段9可带动风道旋转隔板13和烟道旋转隔板14灵活转动并保证与风道固定隔板11和烟道固定隔板12紧密贴合，从而保证密闭性能。管状平行风道和管状平行烟道闭合时，固定隔板与旋转隔板有少许重合。风道旋转隔板13、烟道旋转隔板14的常态位置管道呈关闭状态。
当壁挂炉准备工作时，风机启动，电信号或风压信号使开关电路闭合，为驱动器10供电，蜗杆(齿轮)15驱动旋转段9上的蜗齿(齿条)16使旋转段9顺时针旋转45度，风道旋转隔板13和烟道旋转隔板14与风道固定隔板11和烟道固定隔板12分别重合，以分别将管状平行风道23和管状平行烟道33打开，使通风和排烟顺畅，壁挂炉能够正常工作。当壁挂炉熄火后，风机停止工作，电信号或风压信号消失，开关电路断开，驱动器10断电，蜗杆(齿轮)15驱动旋转段9上的蜗齿(齿条)16带动旋转段9逆时针旋转45度，
风道旋转隔板13和烟道旋转隔板14随旋转段9回位，分别将管状平行风道23和管状平行烟道33封死，从而杜绝冷空气侵入壁挂炉内，实现了节能保温目的。由于在管状平行风道和管状平行烟道中加入了隔板，为保证壁挂炉正常工作，本申请中管状平行风道23和管状平行烟道33比风道2和烟道3适当加大了直径尺寸(例如管状平行风道23和管状平行烟道33按等流量原则比风道2和烟道3适当加大了直径尺寸)，但两端与原风道2和烟道3插接，以保证正常安装。
本申请的第三种优选方式是风道2与烟道3同轴混合控制形式，如图3所示，该图3示出的机械结构由驱动器1(即，蝶阀驱动器)、烟道蝶阀6、蝶阀驱动器轴17、风道密封板18、风道密封板定位螺杆19(四根均匀分布)、风道密封板定位弹簧20(四根均匀分布)、风道密封板驱动器21、拨叉22等组成。风道2在外，烟道3在内。烟道蝶阀6与风道密封板18为常闭状态。风道密封板18为方形结构，中间有一大圆孔，套在烟道3上可沿烟道3做轴向移动，四角均匀分布四个孔，风道密封板定位螺杆19分别由四个孔穿过。四根风道密封板定位螺杆19穿过风道密封板的四个角，定位安装于壁挂炉顶部内侧，对风道密封板18起导向作用，四根风道密封板定位弹簧20分别套在密封板定位螺杆19上，以保证风道密封板18紧密封住风道2。风道密封板驱动器21固定于壁挂炉顶部内侧，拨叉22一端固定在风道密封板驱动器21上，另一端挂在风道密封板18上，风道密封板驱动器21工作时，可通过拨叉22控制风道密封板18克服风道密封板弹簧20的阻力沿烟道3向下做轴向移动。
壁挂炉内的进风口处装有风道密封板18；当壁挂炉准备工作时，风机启动，电信号或风压信号使开关电路闭合，为驱动器1(蝶阀驱动器)和风道密封板驱动器21供电，驱动器1上的蝶阀驱动器轴17带动烟道蝶阀6顺时针旋转90度，连通壁挂炉与室外的烟道3。风道密封板驱动器21通过拨叉22带动风道密封板18沿烟道3轴线向下移动，以打开风道2，使壁挂炉能够正常工作。当壁挂炉熄火后，风机停止工作，电信号或风压信号消失，开关电路断开，驱动器1和风道密封板驱动器21断电，蝶阀驱动器轴17带动烟道蝶阀6逆时针旋转90度回位将烟道3封死。风道密封板驱动器21带动拨叉22回位，风道密封板18在四根风道密封板定位弹簧20的作用下回位，封住风道2从而杜绝冷空气侵入壁挂炉内，实现了节能保温目的。
