在冬季，人们经常也会使用制热装置进行送风取暖，例如，制热装置可以为热风机， 热风机的外形与挂机空调类似，但是只能进行制热。基于空气的热传导，导风板50向下开启时热气流沿导风板50向下吹出，能够更好地与房间内的冷空气进行热量交换。这样，制热装置的导风板50通常设置为向下开启进行送风。
现有的热风机的导风板50宽度都较小，在出风口处斜向下进行送风，热气流吹出后无法到达地面，只能与房间上方的冷空气进行热交换，房间内的温度分布不均匀，用户经常感到脚冷，制热效果较差。
本公开实施例提供了一种制热装置，如图1所示。该制热装置的导风板50为“大导板式”导风板50，具有较大的宽度，导风板50的宽度大于或者等于100毫米。在连杆组件的带动下导风板50能够先伸出出风口后再向下开启，增大了送风范围和送风距离。热气流到达导风板50后能够形成射流沿导风板50的内侧壁吹向地面，进行贴附送风，提高了制热装置的制热效果。
在一些实施例中，制热装置包括上述的用于导风板50的连杆组件，还包括导风板50，连杆组件分别设置于导风板50的两端以共同带动导风板50向下开启。
可选地，制热装置包括多个摆叶，多个摆叶竖直设置于制热装置的出风口处以进行左右摆风。这样，扩大了制热装置左右两侧的送风范围，更好地改善了制热装置的制热效果。
可选地，制热装置还包括驱动元件，驱动元件用于为连杆组件的运动提供驱动力。本公开实施例采用一个驱动元件就可以驱动连杆组件带动导风板50伸出和转动。
本公开实施例中，驱动元件可以为曲柄10，如图10所示。
可选地，曲柄包括转动盘11和转动杆12，转动盘11具有旋转中心，转动杆12的第一端与转动盘11一体式连接，转动杆12的第二端为自由端。
可选地，曲柄与电机驱动连接，电机的驱动轴设置于曲柄的旋转中心处的凹槽内，电机为曲柄的旋转提供驱动力，进而使得曲柄能够与第一连杆20滑动连接、并带动第一连杆20运动。
可选地，传动轴121设置于转动杆12的自由端。这样，传动轴121能够在第一连杆20上滑动，进而带动第一连杆20运动。可以理解地，转动盘11具有与电机接触的驱动面，转动盘11和转动杆12具有与第一连杆20接触的转动面，传动轴121设置于转动杆12的转动面。
本公开实施例还提供了一种用于上述导风板50的连杆组件，如图2至图9所示。
下面将以导风板50右侧的连杆组件为例，对连杆组件的结构和运动过程进行介绍。
在一些实施例中，用于导风板50的连杆组件包括第一连杆20、第二连杆30和轨道板40，第一连杆20一端与导风板50转动连接，第一连杆20包括第一限位部；第二连杆 30一端与导风板50转动连接，第二连杆30包括第二限位部；轨道板40包括第一轨道和第二轨道，第一限位部滑动设置于第一轨道和第二轨道，第二限位部滑动设置于第二轨道，轨道板40用于限定第一连杆20和第二连杆30的运动轨迹；其中，第一轨道包括向一方向延伸的弧形轨道42，以使第一连杆20在外部作用力的带动下与第二连杆30配合，使导风板50先平移伸出出风口后向下开启以进行贴附送风。
本公开实施例提供的运动机构包括第一连杆20、第二连杆30和轨道板40，轨道板40设置有第一轨道和第二轨道。第一连杆20的第一限位部同时与第一轨道和第二轨道相匹配，第二连杆30的第二限位部与第二轨道相匹配，第一轨道设置有弧形轨道42。这样，通过轨道板40能够限定第一连杆20和第二连杆30的运动轨迹，使得第一连杆20在外部的作用力的驱动下能够带动导风板50伸出出风口后向下开启，从出风口吹出的气流到达导风板50后能够形成射流吹向地面，进行贴附送风，使得房间内能够尽快达到预设温度，提高了制热装置的制热效果。同时，沿导风板50吹出的气流的送风范围更大，使得单位面积内的风量减小，送风更为柔和，提高了用户的舒适度。并且，本公开实施例提供的连杆组件，第一连杆20在一个外部作用力的作用下就可以实现导风板50的伸出和转动，简化了连杆组件的结构，实现了远距离、大范围送风的效果。
可选地，以第一连杆20与导风板50的连接点沿导风板50伸出方向所在的直线在轨道板40上的垂直投影线为基准线，弧形轨道42的起始端设置于基准线上，弧形轨道42的末端设置于基准线的上侧。
如图3所示，第一连杆20与导风板50的连接点沿导风板50伸出方向所在直线的投影线在轨道板40上的垂直投影线为AB，AB即上述基准线，将基准线考虑为一条水平的直线，那么，弧形轨道42的末端位于基准线AB的上侧。即，弧形轨道42的形状类似“人”字的撇，弧形轨道42从基准线AB向基准线AB的上侧延伸。
可选地，第一轨道还包括第一直线轨道41，第一直线轨道41呈直线状沿基准线设置且与弧形轨道42的起始端连通；其中，第一连杆20先沿第一直线轨道41运动，带动导风板50平移伸出出风口至第一预设位置，之后，第一连杆20进入弧形轨道42的起始端并沿弧形轨道42运动，第二连杆30沿第二轨道运动，进而带动导风板50向下开启。
本公开实施例中，第一预设位置为导风板50平移伸出出风口并即将开始转动的位置，如图12所示，此时，导风板50与出风口之间具有一定距离、且导风板50可以在第一预设位置向上开启。本公开实施例中，导风板50的转动位置不限定于在第一预设位置处，第一预设位置为导风板50转动的初始位置，导风板50的转动可以理解为边伸出边转动。
本公开实施例中，驱动元件为第一连杆20的运动提供驱动力，由于第一连杆20和第 二连杆30都与导风板50转动连接，这样，通过第一连杆20将驱动力传递给第二连杆30，使得第二连杆30也能够跟随第一连杆20同步直线运动，共同带动导风板50平移伸出至第一预设位置，之后，第一连杆20沿弧形轨道42运动，第二连杆30继续沿轨道板40的直线轨道运动，第一连杆20和第二连杆30产生相对运动，进而带动导风板50向下开启。
可选地，第一限位部至少包括两个滑动柱。可选地，第一轨道和第二轨道内都设置有滑动柱。
如图7所示，第一限位部包括第一滑动柱25和第二滑动柱26，第一滑动柱25设置于第一连杆20的顶端，第二滑动柱26设置于第一连杆20的中部。第一滑动柱25滑动设置于第一轨道内，第二滑动柱26滑动设置于第二轨道中的一条直线轨道内。当第一滑动柱25从第一直线轨道41运动到弧形轨道42时，第二连杆30一直沿第二轨道作直线运动，第一连杆20会与第二连杆30产生相对运动，第一连杆20发生运动改向，进而与第二连杆30配合带动导风板50向下开启。
可选地，第二限位部至少包括两个滑动柱，滑动柱滑动设置于第二轨道内。
如图8所示，第二连杆30的第二限位部包括第三滑动柱31、第四滑动柱32和第五滑动柱33，上述三个滑动柱呈三角形排布。这样，提高了轨道板40对于第二连杆30的运动轨迹的限位效果。
可选地，第一直线轨道41包括直线段和过渡段，过渡段设置于直线段与弧形轨道42的连通处，且过渡段两侧沿都向弧形轨道42延伸的方向呈弧形设置，过渡段用于避免导风板50在第一预设位置处突然加速。
如图3所示，图3中用虚线将直线段和过渡段分别示意，第一直线轨道41的起始段为直线段，第一直线轨道41的用虚线围设的部分为过渡段。第一直线轨道41若不设置过渡段，导风板50的转动速度会在第一预设位置处突然加快。从视觉上看，导风板50突然从平移伸出的状态转变为快速转动的状态，这样，直接影响了用户体验。第一直线轨道41设置过渡段后，导风板50能够从平移伸出状态逐渐开始发生转动，不会发生突然加速的情况，提高了对导风板50的运动过程的精准控制程度。
可选地，第一连杆20沿第一直线轨道41和弧形轨道42运动的时间占比大于或等于0.5，且小于或等于0.7。
通过对第一滑动柱25在第一直线轨道41和弧形轨道42内运动时间的占比进行限定，可以使得导风板50在向上开启的过程中以适中的速度进行转动。同时，导风板50也能够伸出合适的距离后再进行转动，避免导风板50碰到制热装置的壳体。例如，第一滑动柱25在第一直线轨道41和弧形轨道42内运动的时间占比可以为2:3，或者3:5等。
可选地，第二轨道包括多条平行的直线轨道，且多条直线轨道设置于弧形轨道42的下侧。
可选地，第二轨道包括第二直线轨道44、第三直线轨道45和第四直线轨道46，第二直线轨道44沿导风板50伸出的方向设置且与第一直线轨道41都位于上述基准线上；第三直线轨道45设置于第二直线轨道44的一侧；第四直线轨道46设置于第二直线轨道44的另一侧；其中，第二直线轨道44、第三直线轨道45和第四直线轨道46都位于第一轨道的下侧。
可选地，第二直线轨道44、第三直线轨道45和第四直线轨道46为贯穿轨道板40的轨道槽。这样，第二滑动柱26和第二限位部的三个滑动柱能够在轨道槽内稳固地滑动，提高了连杆在轨道内运动的稳定性。其中，第三滑动柱31在第二直线轨道44内运动，第四滑动柱32在第三直线轨道45内运动，第五滑动柱33在第四直线轨道46内运动。
可选地，第二连杆30还设置有贯穿第二连杆30板面的贯穿滑道35。第二连杆30上贯穿滑道35的设置，使得第一连杆20的第二滑动柱26能够穿过该贯穿滑道35沿第二轨道运动。
可选地，第一连杆20设置有通槽21，曲柄10的传动轴121滑动设置于通槽21内以为第一连杆20提供运动的驱动力。
可选地，通槽21呈直线型，曲柄10的传动轴121运动形成的圆的直径小于或者等于通槽21的长度。这样，使得曲柄10的传动轴121可以从初始位置沿第一方向或者第二方向旋转90°后，并继续旋转，曲柄10的旋转角度不受通槽21的长度的限定。
可选地，第一连杆20还包括镂空区22，镂空区22设置于通槽21的上方，镂空区22的边缘与第一连杆20的外沿之间的距离大于或等于0.5毫米。
如图6所示，镂空区22设置于通槽21的上方，镂空区22的设置使得第一连杆20轻量化，这样，在电机驱动曲柄带动第一连杆20运动的过程中，能够减小电机的力矩。同时，对镂空区22的大小进行限定也能够使得第一连杆20具备运动的可靠性。
可选地，弧形轨道42所在圆的圆心位于弧形轨道42的下侧，以使导风板50在向下开启的过程中匀速转动。
本公开实施例中，图3所示的弧形轨道42所在圆的圆心位于弧形轨道42的下侧，即弧形轨道42的形状呈外凸状，这样，导风板50在向下开启的过程中能够匀速转动，避免导风板50伸出出风口后出现快速转动向下开启的情况。
本公开实施例还提供了另一种轨道板40，如图4所示。图3和图4所示的两个轨道板40中的弧形轨道42的弯曲方向不同。图4所示的弧形轨道42为内凹状，即，弧形轨 道42所在圆的圆心位于弧形轨道42的上侧。
以上两种形状不同的弧形轨道42，与连杆组件的其他部件配合带动导风板50运动的运动轨迹是不同的，弧形轨道42的弯曲方向能够影响导风板50在转动过程中的速度。图3所示的轨道板40的弧形轨道42是外凸状的，这样，导风板50在伸出出风口后能够匀速转动。图4所示的轨道板40的弧形轨道42是内凹状的，这样，导风板50在伸出出风口后的转动速度会越来越快，导风板50会快速向下开启，直接影响用户的感官体验。
为了更直观的体现导风板50在伸出出风口后的转动速度，本公开实施例提供了运动机构采用以上两种轨道板40带动导风板50转动的转动速度对比示意图图5。其中，导风板50的转动速度可以理解为转动角速度。
如图5所示，图中的实线为采用图3所示的轨道板40的导风板50转动速度随时间的变化走向。在0-2秒的时间段内，导风板50的转动速度为0，说明导风板50在伸出过程中未发生转动；在2-4秒的时间段内，导风板50的转动速度开始逐渐增大，说明导风板50伸出出风口后逐渐开始转动；在4-10秒的时间段内，导风板50的转动速度维持不变，说明导风板50在转动过程中能够基本保持匀速的状态。
如图5所示，图中的虚线为采用图4所示的轨道板40的导风板50转动速度随时间的变化走向。在0-2秒的时间段内，导风板50的转动速度为0，说明导风板50在伸出过程中未发生转动；在2-4秒的时间段内，导风板50的转动速度开始逐渐增大，说明导风板50伸出出风口后开始转动；在4-10秒的时间段内，导风板50的转动速度逐渐增大，说明导风板50在转动过程中的速度越来越快。
通过上述图5所示的采用两种轨道板40测试导风板50的转动速度的仿真实验数据的对比，从4-10秒时间段的导风板50的转动速度曲线可以看出，本公开实施例提供的具有外凸状的弧形轨道42的轨道板40，能够与连杆组件的其他部件配合，带动导风板50伸出出风口后匀速转动，避免了导风板50在转动过程中越来越快的现象，提高了用户的感官体验。
可选地，弧形轨道42的弧度大于或等于10°，且小于或等于25°。这样，导风板50能够伸出出风口后匀速地转动至最大开启角度。
可选地，第一连杆20和第二连杆30之间设置有限位机构，限位机构用于防止第二连杆30在导风板50运动过程中的晃动。
在导风板50的运动过程中，第二连杆30只有一端与导风板50进行了限位，在导风板50运动的过程中，如果用手拨动第二连杆30，第二连杆30会发生上下晃动，第二连杆30的可靠性较低。并且，第二连杆30上下晃动的同时也会影响导风板50的正常运动，降 低了整个运动机构的可靠性。
可选地，限位机构包括限位柱36和定位槽23，限位柱36设置于第二连杆30；定位槽23倾斜设置于第一连杆20，限位柱36滑动设置于定位槽23内；其中，在导风板50向下开启的过程中，限位柱36在定位槽23内滑动以限定第二连杆30的位置。
第二连杆30的一端与导风板50转动连接，第二连杆30的限位柱36设置于定位槽23内，这样，第二连杆30有了2个定位处，从而能够对第二连杆30的位置进行限定。不管导风板50运动到什么位置，限位柱36一直都在定位槽23内，用户无法用手拨动第二连杆30，提高了第二连杆30的可靠性。
可选地，第二连杆30具有与第一连杆20相对的第一板面，限位柱36设置于第一板面、且位于第二连杆30的上部，如图9所示。
可选地，第一连杆20具有与第二连杆30相对的限位板面，定位槽23设置于限位板面的中部。
在导风板50处于关闭状态时，本公开实施例的运动机构中的第一连杆20和第二连杆30是部分抵接的状态。第二连杆30具有与第一连杆20相对的第一板面，第一连杆20具有与第二连杆30相对的限位板面。限位柱36位于第二连杆30第一板面的上部，定位槽23位于第一连杆20的限位板面的中部，即，第一连杆20的中下部与第二连杆30抵接。并且，在导风板50的运动过程中，限位柱36一直处于定位槽23内，第二连杆30的上端一直保持限位状态，避免了第二连杆30的晃动。
可选地，定位槽23的上侧沿呈直线状。导风板50在关闭状态下，第二连杆30的限位柱36位于定位槽23的下端，导风板50向下开启到最大角度的状态下，限位柱36位于定位槽23的上端。可以理解的是，定位槽23的形状即为第二连杆30的限位柱36与第一连杆20的抵接点的变化轨迹。通过该变化轨迹对第二连杆30的上端进行限位，这样，用户用手无法拨动第二连杆30，提高了连杆组件的可靠性。
本公开实施例中，第一连杆20和第二连杆30都与导风板50转动连接。
可选地，第一连杆20的一端设置有第一连接孔27，第二连杆30的一端设置有第二连接孔34。
可选地，第一连杆20和第二连杆30与导风板50的安装座52之间设置有连接件60，连接件60分别与第一连接孔27和第二连接孔34铰接，连接件60与安装座52卡接，如图12所示。
可选地，连接件60包括连接主体64、第一安装部61、第二安装部62和卡接部63，如图11所示。第一连接孔27与第一安装部61铰接，第二连接孔34与第二安装部62卡 接。通过在导风板50的安装座52与第一连杆20和第二连杆30之间设置连接件60，可以便于导风板50的拆装，提高了导风板50的装配效率。
本公开实施例提供的用于导风板50的运动机构的运动方式如下：
导风板50在关闭状态下的连杆组件的初始状态如图2所示。当曲柄10沿第一方向旋转时，传动轴121在第一连杆20的通槽21内滑动以带动第一连杆20和第二连杆30运动。其中，第一连杆20沿第一直线轨道41的直线段运动，第二连杆30沿第二轨道作直线运动，进而带动导风板50直线运动伸出至第一预设位置。第一预设位置可以理解为第一连杆20的第一滑动柱25运动至直线段的末端时所对应的导风板50的位置，如图13所示。本公开实施例中，第一方向为基于图13所示的逆时针方向。
当导风板50到达第一预设位置后，传动轴121继续在通槽21内滑动，带动第一连杆20的第一滑动柱25进入第一直线轨道41的过渡段并沿弧形轨道42运动，第一连杆20的第二滑动柱26继续在第二轨道内运动，这样，第一连杆20开始运动转向，第一连杆20与第二连杆30产生相对运动，进而共同带动导风板50向下开启，满足了制热装置的送风需求，如图14所示。
以上描述和附图充分地示出了本公开的实施例，以使本领域的技术人员能够实践它们。其他实施例可以包括结构的以及其他的改变。实施例仅代表可能的变化。除非明确要求，否则单独的部件和功能是可选的，并且操作的顺序可以变化。一些实施例的部分和特征可以被包括在或替换其他实施例的部分和特征。本公开的实施例并不局限于上面已经描述并在附图中示出的结构，并且可以在不脱离其范围进行各种修改和改变。本公开的范围仅由所附的权利要求来限制。
