Description

空调器导风板 技术领域
本发明涉及空调技术领域，特别是涉及一种空调器导风板。
背景技术
随着社会日益发展以及人们生活水平不断提高，环境调节电器如空调器等越来越普及。导风板作为空调器内机的性能及结构组件，是空调器不可缺少的一部分。导风板作为出风导向且具有一定的静压恢复功能，其结构设计对空调的性能以及用户的体验度有着重要影响。但是目前的空调导风板主要存在以下两点问题：(1)摆风时，风道吹出的气流直接冲击导风板，导风板阻力大，整机风量损失大、送风噪声提高、整机性能下降，影响用户体验；(2)制冷时，当导风板位置与出风方向存在一定夹角时，导风板前端背风侧会存在因潮湿空气倒灌引起的凝露问题。
目前，针对空调平直导风板摆风时阻力较大(达到相同摆风角度)的问题，通常的做法是将导风板横截面结构设计成弧形曲面，以减少摆风时导风板的阻力，这种方法仅针导风板的结构形状做出改善，对导风板阻力改善有限。同时，这种弧形导风板会恶化空调导风板前端背风侧的凝露情况。而目前解决空调制冷时导风板凝露最常用的方法有：(1)单侧隔热法，在导风板冷风侧增加隔热衬垫，使导风板的背风侧表面保持室温，与室内常温空气接触也不会凝露。这种方法对导风板隔热衬垫的要求很高，工艺复杂，材料、人工成本较高，并且导风板显得很厚，影响整机美观，用户体验度不高。(2)冷风包裹法，即用冷风同时吹过导风板两侧，形成冷风包膜，阻止导风板与室内温湿常温空气接触来抑制凝露。这种方法要求空调导风板必须同时被冷风包裹才有效，导风板的宽度方向与空调出风方向夹角越小防凝露效果越好。但是当导风板旋转时，随着导风板宽度方向与空调出风方向夹角增大，导风板背风侧会产生负压区吸引温湿常温空气倒灌，在导风板背风侧形成凝露。随着用户对空调内机外观需求的提升，空调导风板结构有越来越多的被设计成弧形，这种弧形结构会进一步恶化导风板的凝露现象。
发明内容
本发明的一个目的是减小或消除导风板的负压区，引导换热气流流向，减小换热气流与导风板之间的摩擦。
本发明一个进一步的目的是防止温湿空气倒灌，防止导风板凝露。
特别地，本发明提供了一种用于空调器的导风板，具有迎风面和与迎风面相对的背风面，其特征在于导风板中设置有连通迎风面和背风面的气流通道，以将吹送至迎风面上的部分气流经由气流通道导向至背风面的中前部区域或背风面的前缘区域。
可选地，导风板还具有：进风口，位于至少覆盖迎风面中后部区域的进风区域，以引导部分气流经由进风口进入气流通道；和出风口，位于背风面的中前部区域或背风面的前缘区域，以引导部分气流经由出风口离开气流通道。
可选地，进风口包括位于进风区域内的多个进风槽；进风区域自迎风面的后缘覆盖至迎风面的中部区域；出风口形成于背风面的前缘和迎风面的前缘之间。
可选地，气流通道包括：进风区段，设置为在气流通道的延伸方向上自进风口朝向出风口延伸第一预设距离；加速区段，设置为自进风区段的进风末端朝向出风口延伸第二预设距离；和出风区段，设置成自加速区段的加速末端朝向出风口延伸第三距离至出风口。
可选地，出风区段和出风口还设置成，使气流流经出风区段和流经出风口时的流动方向不变。
可选地，气流通道的位于加速区段的第二内部宽度配置成，沿进风区段指向出风区段的方向逐渐减小。
可选地，气流通道的位于出风区段的第三内部宽度配置成，沿加速区段指向出风口的方向保持不变，且出风口的宽度与第三内部宽度相同。
可选地，多个进风槽配置成，使部分气流进入气流通道的进风方向和部分气流离开气流通道的出风方向之间的夹角小于90°。
本发明还提供了一种空调器导风板，该空调器导风板包括：后侧板，其中上部开设有进风口，以供空调器的风机吹出的气流的至少一部分进入；以及前侧板，连接于后侧板的外侧，且前侧板和后侧板之间形成有气流通道，导风板的底部开设有与气流通道连通的出风口，以供通过进风口进入气流通道的气流导出。
可选地，出风口至前侧板底端的距离与导风板的宽度的比值小于等于预设值。
可选地，气流通道的中部至下部渐窄，以使进入气流通道的气流加速。
可选地，后侧板为平直结构，前侧板为弧形结构。
可选地，进风口包括一个或多个进风孔/槽。
可选地，进风孔或进风槽的进风方向与后侧板末端方向的夹角小于90°。
可选地，前侧板和后侧板均为平直结构。
可选地，气流通道由上至下的宽度相同。
可选地，预设值为1/4。
本发明的空调器导风板包括：后侧板，其中上部开设有进风口，以供空调器的风机吹出的气流的至少一部分进入；以及前侧板，连接于后侧板的外侧，且前侧板和后侧板之间形成有气流通道，导风板的底部开设有与气流通道连通的出风口，以供通过进风口进入气流通道的气流导出，通过在后侧板和前侧板之间设置气流通道，以一种双层板以及中间空心的组合结构，使得至少一部分气流通过进风口进入气流通道并从出风口导出，可以减小或消除导风板的负压区，引导换热气流流向，减小换热气流与导风板之间的摩擦，并可以防止温湿空气倒灌，进而防止导风板凝露，避免影响用户的使用体验。
进一步地，本发明的空调器导风板与空调器，出风口至前侧板底端的距离与导风板的宽度的比值小于等于预设值，即出风口尽量设置于前侧板的底部，以实现对换热气流的引导，并且气流通道的中部至下部可以渐窄，以使进入气流通道的气流加速之后从出风口导出，从而形成更低的低压区，吸引导风板外侧的气流向其汇聚，引导气流沿着导风板方向偏转，优化了对气流的引导效果，进而可以更加有效地防止导风板出现凝露现象，提升用户的使用体验。再进一步地，位于加速区下游的隙宽均匀不变的出风区可起到对加速后的气流进行整流的作用，使最终吹出导风板的气流保持有较高的流速。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。在本发明的描述中，术语“上”、“下”、“前”、“后”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明而不是要求本发明必须以特定的方位构造和操作，因此不能理解为对本发明的限制。
本实施例提供了一种空调器导风板，可以减小或消除导风板的负压区，引导换热气流流向，减小换热气流与导风板之间的摩擦，并可以防止温湿空气倒灌，进而防止导风板凝露，避免影响用户的使用体验。
图1是根据本发明一个实施例的空调器导风板的剖视图。图2是根据本 发明一个实施例的导风板安装于立式空调器且处于关闭状态下的示意性主视图。图3是沿图2中的剖切线A-A截取的示意性剖视图。图4是图3中导风板10处于打开状态下的示意性剖视图。
如图1所示，本实施例的空调器导风板10一般性地可以包括：后侧板11和前侧板12，其中的“前”和“后”是指当导风板10安装于空调器1送风口并处于关闭状态时，朝向空调器1外侧且大致朝前的板即为前侧板12，朝向空调器1内侧且大致朝后的板即为后侧板11。本领域技术人员均可以理解，当导风板10处于完全打开或部分打开的状态时，前侧板12和后侧板11并不一定分别朝向空调器1的前侧和后侧。
后侧板11的中上部开设有进风口111，以供空调器1的风机2吹出的气流的至少一部分进入。前侧板12连接于后侧板11的外侧。具体地，前侧板12和后侧板11可以为可分离的两块式结构，也可为固定在一起的一体式结构，以共同构成导风板10。前侧板12和后侧板11之间形成有气流通道13，导风板10的底部开设有与气流通道13连通的出风口121，以供通过进风口111进入气流通道13的气流导出。即当导风板10安装于空调器1送风口并处于关闭状态时，导风板10靠近空调器1的风机2的一侧为后侧板11，导风板10远离空调器1的风机2的一侧为前侧板12。也即是，用于空调器1的导风板10可具有迎风面110和与迎风面110相对的背风面120，其中迎风面110即是后侧板11的暴露在风机2吹出的气流中的板面，背风面120即是前侧板12的背向后侧板11一侧的板面。上述用词“中上部”、“底部”是以图1中的方位对导风板10结构进行的说明，可以理解地，当导风板10处于图4所示的状态时，图1中后侧板11的中上部即是图4中后侧板11的中后部，图1中导风板10的底部即是图4中导风板10的前部。
参见图4，气流通道13可设置于导风板10中且连通迎风面110和背风面120，以将吹送至迎风面110上的部分气流经由气流通道13导向至背风面120的中前部区域或背风面120的前缘区域。也即是，当导风板10处于如图4中的打开位置时，风机2促使气流自导风板10朝向空调器1内侧的后缘区域1001朝向导风板10朝向空调器1外侧的前缘区域1002流动，接触导风板10的部分气流由此可经由进风口111进入气流通道13并经由出风口121离开。
在一些实施例中，进风口111可位于至少覆盖迎风面110中后部区域的 进风区域，以引导部分气流经由进风口111进入气流通道13。出风口121可位于背风面120的中前部区域或背风面120的前缘区域，以引导部分气流经由出风口121离开气流通道13。
也即是，图1中与L1所对应的后侧板12上的区域即可为迎风面110上的进风区域。进风区域与出风口121分别位于打开状态下的导风板10的靠近风机2的一侧和远离风机2的一侧，以使流经气流通道13的部分气流与自导风板10外部流出空调器1的气流的流动方向大致相同，保证空调器1送风气流的流速。
图5a是图1中导风板的示意性前视图，其中示出了迎风面。图5b是图5a所示导风板的示意性局部放大视图，其中细节B示出了进风口。图6a是图1中导风板的示意性后视图，其中示出了背风面。图6b是图6a所示导风板的示意性局部放大视图，其中细节C示出了出风口。
参见图5a和5b，在一些实施例中，进风口111可包括位于进风区域内的多个进风槽。如本领域技术人员所熟识的，槽一般具有狭长的开口。进风槽可以具有与导风板10长度方向相平行的、且在长度方向基本横贯导风板10的狭长开口。进风区域为自迎风面110的后缘覆盖至迎风面110的中部区域，多个进风槽的狭长开口可均匀间隔且相互平行地设置在进风区域内。需要说明的是，本文中的“中部区域”并非指导风板10的几何中心位置，而是指将导风板10自上向下或自后向前等分为多个子部分，其中覆盖导风板10几何中心的中间子部分和邻接该中间子部分的一个或几个其他子部分。“中下部区域”或“中前区域”则是指中部区域加上位于中部区域下部或前部的一个或几个子部分。
进一步地，参见图1和6b，出风口121可形成于背风面120的前缘和迎风面110的前缘之间。也即是，以图1为例，前侧板12和后侧板11的底部之间留有间隙以形成出风口121，由此无需在前侧板12上开口，以简化制造工序。在另一些实施例中，出风口121也可为开设在前侧板12上的孔或槽(参见下文详述)。
继续参见图1，在一些实施例中，气流通道13可包括：进风区段L1、加速区段L2和出风区段L3(分别对应导风板的进风区L1、加速区L2和出风区L3)。具体地，进风区段L1设置为在气流通道13的延伸方向上覆盖进风区域。也即是，进风区L1自迎风面110的上部(进风口111处)向下 延伸第一预设距离，该第一预设距离与进风区域在导风板10的宽度方向上的跨度大致相等。加速区段L2设置为自进风区段L2的进风末端朝向出风口121延伸第二预设距离。出风区段L3设置为自加速区段L2的加速末端朝向出风口121延伸第三距离至出风口121。
在一些实施例中，出风口121至前侧板12底端的距离与导风板10的宽度的比值小于等于预设值。即，以图1为例，出风口121尽量设置于前侧板12的底部，以实现对换热气流的引导。导风板10的宽度即为后侧板11或前侧板12的顶部至底部的距离,也即是，导风板10的宽度方向为图1中的上下方向。在一种优选的实施例中，该预设值可以为1/4。
气流通道13各区段的长度可如图1所示，导风板10整体宽度为L，按照空调器1的出风方向可以分为三个区域：进风区L1、加速区L2以及出风区L3。其中，进风区L1为导风板10的顶部至最下边一个进风孔/槽的距离；加速区L2为最下边一个进风孔/槽至出风口121顶部的距离；出风区L3为出风口121顶部至导风板10底部的距离。如上文所描述的，出风口121至前侧板12底端的距离与导风板10的宽度的比值小于等于预设值。即L3/L小于等于预设值，在一种优选的实施例中，该预设值可以为1/4。
进一步地，参见图1，在一些实施例中，后侧板11可为平直结构，后侧板11的迎风面110和内部表面可均为平直结构。前侧板12为弧形结构，前侧板12的背风面120和内部表面可均为弧形结构，弧形结构的弧度可以相同或不同，弧形结构配置成使气流通道13自中部至下部渐窄，进而使进入气流通道13的气流加速。
换言之，气流通道13的位于加速区L2的第二内部宽度W2可配置成，沿进风区段L1指向出风区段的方向逐渐减小。气流通道13的位于出风区段L3的第三内部宽度W3可配置成，沿加速区段L2指向出风口121的方向保持不变，且出风口121的宽度与第三内部宽度W3相同。气流通道13的位于进风区L1的第一内部宽度W1配置成，沿气流流动方向逐渐增大，以使进风区L1与加速区L2和出风区L3共同构成弧形。其中，气流通道13的内部宽度为在导风板10的厚度方向上的尺寸，也即是在图1中的前后方向上的尺寸。
继续以图1为例，加速区L2内的后侧板11的内部表面与前侧板12的内侧表面之间的隙宽可自上向下逐渐减小，出风区L3内的后侧板11的内部 表面与前侧板12的内侧表面之间的隙宽可自上向下均匀设置，以对加速后的气流进行整流，使最终吹出导风板10的气流保持有较高的流速。加速区L2末端的隙宽可与出风区L3始端的隙宽相同以实现气流通道13内部的平滑过渡。出风区L3末端的隙宽可与出风口121的开口大小相同，以使气流流经出风区段L3和流经出风口121时持续保持较高的流速。也即是，出风区段L3和出风口121可设置成，使气流流经出风区段L3和流经出风口121时的流动方向不变。
在不脱离本发明精神和教导的情况下，在某些替代性的实施例中，加速区L1和隙宽均匀的部分也可能不是必须的。
图7是根据本发明另一个实施例的导风板的剖视图。图8a是图7中导风板的示意性前视图，其中示出了迎风面。图8b是图8a所示导风板的示意性局部放大视图，其中细节D示出了进风口。图9a是图7中导风板的示意性后视图，其中示出了背风面。图9b是图9a所示导风板的示意性局部放大视图，其中细节E示出了出风口。
如前所述，出风口121可位于由前侧板12与后侧板11限定出的气流通道13的底部。如图7所示，出风口121也可以设置于前侧板12的底部。也即是，以图4中导风板10安装于空调器1的状态为例，出风口121可形成于背风面120的中前部区域。
进一步地，本实施例的空调器导风板10中的进风口111包括多个进风孔，可以为一种镂空的结构。空调器导风板10中的出风口121为一个出风槽。在其他一些实施例中，进风孔还可以为进风槽、进风条等。也即是，出风口可为开设于背风面的一个条形槽，且该条形槽的出风方向与气流通道13内的气流流动方向之间可形成一个锐角。
在一些优选的实施例中，如图1和7所示，进风孔或进风槽的进风方向与后侧板11末端方向的夹角α小于90°。也即是，经由进风口111进入气流通道13的气流的进风方向与自进风口111指向位于后侧板11气流流动末端的出风口121的方向大致呈同向。该角度便于空调器1的风机吹出的气流进入气流通道13。
换言之，多个进风槽可配置成，使气流进入气流通道13的进风方向和气流离开气流通道13的出风方向之间的夹角小于90°。具体地，该出风方向可以为相对于图1所示导风板10竖直向下的方向。此时，进风槽(图1 所示)所引导的进风方向为倾斜向下，其与竖直向下的出风方向之间的夹角α小于90°。在另一些实施例中，前述出风方向还可以为相对图7所示导风板10倾斜向下的方向。此时，进风槽(图7所示)所引导的进风方向为横向，其与倾斜向下的出风方向之间的夹角也小于90°。
图10a-10c是根据本发明一些替代性实施例的空调器导风板的剖视图。
图10a-10c中的空调器导风板10的前侧板12和后侧板11均为平直结构，其中图10a和10b中导风板10的气流通道13由上至下的宽度相同，但图10b中导风板10的气流通道13为倾斜的气流通道13。
图10c中导风板10的气流通道13自中部至下部渐窄，以使进入气流通道13的气流加速。此外，图10a中导风板10的进风口111包括多个进风孔/槽，而图10b和10c中导风板10的进风口111均包括一个进风槽。
图11是现有技术中空调器导风板的气流倒灌示意图，图12是根据本发明一个实施例的空调器导风板10的气流引导示意图。如图11所示，现有技术中的空调器导风板旋转时，随着导风板宽度方向与空调出风方向夹角增大，导风板背风侧会产生负压区吸引温湿常温空气倒灌，在导风板背风侧形成凝露，严重影响用户的使用体验。其中图11中的椭圆形处即为形成的负压区。而图12中根据本发明一个实施例的空调器导风板10，可以引导空调器风机吹出的至少一部分气流通过气流通道13导出，使得气流沿着导风板10方向偏转。
本实施例的空调器导风板10通过在后侧板11和前侧板12之间设置气流通道13，以一种双层板以及中间空心的组合结构，使得至少一部分气流通过进风口111进入气流通道13并从出风口121导出，可以减小或消除导风板10的负压区，引导换热气流流向，减小换热气流与导风板10之间的摩擦，并可以防止温湿空气倒灌，进而防止导风板10凝露，避免影响用户的使用体验。
进一步地，本实施例的空调器导风板10，出风口121至前侧板12底端的距离与导风板10的宽度的比值小于等于预设值，即出风口121尽量设置于前侧板12的底部，以实现对换热气流的引导，并且气流通道13的中部至下部可以渐窄，以使进入气流通道13的气流加速之后从出风口121导出，从而形成更低的低压区，吸引导风板10外侧的气流向其汇聚，引导气流沿着导风板10方向偏转，优化了对气流的引导效果，进而可以更加有效地防 止导风板10出现凝露现象，提升用户的使用体验。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
