Description

一种风道的导流结构及包括该导流结构的空调器
本申请要求于2015年8月14日提交中国专利局、申请号为201510500658.3、发明名称为“一种风道的导流结构及包括该导流结构的空调器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及空调器技术领域，尤其涉及一种风道的导流结构及包括该导流结构的空调器。
背景技术
现有技术中，分体式壁挂空调器的室内机的风机通常为贯流风机，而柜式空调器的室内机通常采用离心风机。离心风机能够实现前后进风、上下出风的方式，即沿离心风机的轴向进风、径向出风的方式，进风量和出风量较大。
若将离心风机应用在壁挂式空调内机上，由于离心风机的端部需要设有风道盖板，风道盖板开设有进风口，气流经过进风口后再由离心风机排出至空调器的出风口。由于风道盖板进风一侧为热风，出风一侧为经过冷凝器降温后的冷风，风道盖板会产生冷凝水，进而存在冷凝水会被离心式风机径向甩出的问题。
因此，如何避免离心风机将冷凝水甩出的问题，成为本领域技术人员所要解决的重要技术问题。
发明内容
本发明提供了一种风道的导流结构，其能够将风道盖板上凝结的冷凝水导流出去，进而可以避免离心风机将冷凝水甩出的问题。本发明还提供了一种包括上述导流结构的空调器。
本发明提供的一种风道的导流结构，包括设有开口的风道盖板，所述风道盖板靠近所述开口的位置设置有环绕于所述开口外周、供所述风道盖板上的冷凝水流入的导流槽。
优选地，还包括具有中空部的导流圈，所述导流圈与所述开口的边缘部相连接，且所述导流圈的中空部构成风道的进风口，所述导流槽设置在所述导流圈上。
优选地，所述导流圈设有凸起于所述导流圈的侧面、并向外延伸的凸起部，所述凸起部与所述导流圈的侧面之间具有空间，以形成所述导流槽。
优选地，所述凸起部的外侧面与所述风道盖板的外侧面相平齐，且所述凸起部的外侧面与所述风道盖板的外侧面之间具有间隙，以形成所述导流槽的入口。
优选地，所述导流槽的侧壁横截面形状为弧形。
优选地，所述进风口的边沿为弧面结构，且沿进风方向逐渐缩小。
本发明还提供了一种空调器，包括室内机，所述室内机设有如上任一项所述的导流结构。
优选地，所述空调器的室内机为壁挂式室内机。
优选地，所述室内机设有接水盘，所述导流槽的下部设有与所述接水盘相通、用于将冷凝水排至所述接水盘的排水通道。
本发明提供的一种风道的导流结构，包括设有开口的风道盖板，所述风道盖板靠近所述开口的位置设置有环绕于所述开口外周、供所述风道盖板上的冷凝水流入的导流槽。如此设置，若风道盖板上产生了冷凝水，冷凝水沿着风道盖板流动至靠近进风位置时，冷凝水会流入到导流槽中，进而避免了冷凝水被离心风机甩出的问题。
本发明还提供了一种包括上述导流结构的空调器，如此设置，该空调器避免了因采用离心风机，而导致冷凝水被甩出的问题。

具体实施方式
本具体实施方式提供了一种风道的导流结构，其能够将风道盖板上凝结的冷凝水导流出去，进而可以避免离心风机将冷凝水甩出的问题。本具体实施方式还提供了一种包括上述导流结构的空调器。
本具体实施方式提供的风道的导流结构，包括风道盖板14，风道盖板14设有开口，气流通过该开口进入、并在离心风机16的驱动作用下由其它位置吹出。风道盖板14靠近开口的位置设置有环绕于开口外周、供风道盖板14上的冷凝水流入的导流槽11。
需要说明的是，上述导流槽11可以与风道盖板14为一体式结构，即在风道盖板14上直接加工出一圈导流槽11。
在本具体实施方式的优选方案中，可以在风道盖板14上设置一个导流圈12，上述导流槽11设置在导流圈12上，具体如下所述。导流圈12具有中空部，导流圈12与风道盖板14开口的边缘部相连接，且导流圈12的中空部构成风道的进风口，导流槽11设置在导流圈12上。如此设置，只需单独加工一个导流圈12，而后将导流圈12安装到风道盖板14上即可。
设置在导流圈12的导流槽11可以为在导流圈12上加工出的槽型结构，也可通过在导流圈12上设置凸起部13，凸起部13凸起于导流圈12的侧面、并向外延伸，需要说明的是，上述向外延伸是指凸起部13从导流圈12的侧面凸起之后，向远离中空部的方向延伸。如此设置，在导线圈与凸起部13之间具有一定的空间，该空间即形成了导流槽11。该种导流槽11，位于导流圈12 上部的部分开口向上，容易收集冷凝水，位于导流圈12下部的部分开口向下，在重力作用下即可将冷凝水排出。
本具体实施方式的优选方案中，凸起部13的外侧面与风道盖板14的外侧面相平齐，且凸起部13的外侧面与风道盖板14的外侧面之间具有间隙，以形成导流槽的入口15，即凸起部13的外侧面和风道盖板14的外侧面相平齐，即二者处于同一平面内，凸起部13的顶端与风道盖板14的端部存在一定的间隙，形成导流槽的入口15。如此设置，风道盖板14和导流圈12降低了对气流的扰动，避免出现振动、噪音等问题。
为了进一步降低导流槽11对气流的扰动，进一步地可以将导流槽11的侧壁横截面形状设置为弧形。如此设置，导流槽11的内侧面为流线型，降低了对气流的扰动。
另外，本具体实施方式中，导流圈12的进风口的边沿设置为弧面结构，且沿进风方向逐渐缩小。如此设置，进风阻力较小、进风噪音较小。
本具体实施方式还提供了一种空调器，包括室内机，该室内机设有如上具体实施方式中所述的导流结构。如此设置，本具体实施方式提供的空调器，其能够将风道盖板14上凝结的冷凝水导流出去，进而可以避免离心风机16将冷凝水甩出的问题。
该空调器的室内机优选为壁挂式室内机，如此设置，本具体实施方式提供的壁挂式室内机，能够应用离心风机16，而且不会有冷凝水甩出。
本具体实施方式还提供的空调器，室内机可以设有接水盘(图中未示出)，导流槽11的下部设有与接水盘相通、用于将冷凝水排至接水盘的排水通道(图中未示出)。如此设置，导流槽11内的冷凝水可以导流到接水盘中，进而排出至空调外，防止了冷凝水存在于空调内，对空调器件造成损坏。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
