Description

离子风发生装置及空调室内机 技术领域
本发明涉及空气调节技术，特别是涉及一种离子风发生装置及具有该离子风发生装置的空调室内机。
背景技术
目前，电晕放电离子送风技术作为一种独特的送风系统，以其具有的结构简单、无噪声、有空气净化作用等诸多优点，成为具有极大市场潜力和良好应用前景的技术，成为国内外研究者的一个热点研究方向。离子风的产生源于电晕放电原理：由于高压电的作用，针电极附近电场强度极大，使区域内的大量空气分子产生电离，而在此区域之外的电场较弱，不发生电离过程。在电场的作用下，带电粒子作定向移动，且在运动过程中与不带电的中性粒子碰撞，把部分动能传递给中性粒子，使其一起做定向移动，即产生离子风。
为了减少噪音，现有的一些空调室内机通常采用离子风模块代替送风风机实现送风，或者采用离子风模块和送风风机同时驱动送风。无论如何，离子风模块的性能和送风效果都至关重要。
发明内容
本发明的设计人意识到，在离子风模块中，其针电极与针电极之间的相对位置关系以及针电极与网电极之间的相对位置关系对整个离子风模块的性能起着至关重要的作用。如果由于结构设计强度、长时间使用或其他外力原因导致针网电极之间的相对位置发生变化，那么整个离子风模块的性能就会大打折扣。

所述网状电极在所述进深方向上位于所述针状电极的前侧，所述定型架在所述进深方向上位于所述网状电极的后侧。
可选地，所述网状电极通过胶黏的方式固定在所述定型架上。
可选地，每个所述放电模组还包括用于固定所述多个针状电极的针架，且
所述针架具有多个相互平行的导电杆和多个相互平行的加强筋，所述导电杆和所述加强筋交错设置，每个所述导电杆与每个所述加强筋的相交处均设有一个所述针状电极。
可选地，所述放电模组的数量为多个；且

根据本发明的第二方面，本发明还提供一种空调室内机，包括：
机壳，具有用于供气流流出的至少一个送风口，所述至少一个送风口中的一个或多个送风口处设有用于整流送风的开闭机构；以及
至少一个上述任一所述的离子风发生装置，设置于所述机壳内，以用于提供送往所述至少一个送风口中的一个或多个送风口的离子风。
可选地，具有所述开闭机构的所述送风口呈圆形，且每个所述开闭结构均包括：
中央挡板，其固定不动地设置于相应的所述送风口的中央，且其外周缘与相应的所述送风口的内周缘之间形成出风区域；以及
多个曲形叶片，沿所述中央挡板的周向依次设置，配置成可向所述中央挡板的中心聚拢以至少部分地打开所述出风区域，以及配置成可向背离所述中央挡板中心的方向展开以至少部分地封闭所述出风区域。
可选地，每个所述曲形叶片包括：

内轮廓边缘部，包括第三圆弧形区段和第四圆弧形区段，所述内轮廓边缘部在所述多个曲形叶片聚拢时朝向所述中央挡板的中心；其中
所述第一圆弧形区段和第四圆弧形区段沿指向所述曲形叶片的根端的方向逐渐靠近，以使所述曲形叶片的根端形成渐缩的曲形区域；所述第二圆弧形区段和第三圆弧形区段沿指向所述曲形叶片的末端的方向逐渐靠近，以使所述曲形叶片的末端形成渐缩的曲形区域。

本发明通过定型架对网状电极进行位置和形状固定，能够避免网状电极产生弯曲或变形，使其能够始终保持一平面结构，形成平面电极网。由于定型架相比于细丝网状的网状电极的结构强度大得多，其不会因外力作用而发生位移或变形，因此保证了每个针状电极距网状电极的距离均相同，即保证了针网的间距恒定不变，有效避免了因放电距离不等导致放电不均，从而产生摩擦打火、出现异味的现象，消除了安全隐患。
进一步地，本发明通过设置具有交错设置的多个导电杆和多个加强筋的针架，并将放电模组的针状电极布置在导电杆和加强筋的相交点上，能够保证每个针状电极均能够通过导电杆和加强筋的双重作用得到固定。在针状电极的数量确定后，导电杆和加强筋之间的间距和相对位置是恒定不变的，且导电杆和加强筋的结构强度相对较大，几乎不会因外力作用发生位移或变形，因此能够可靠地保证每个针状电极的相对位置恒定不变，保证了离子风发生装置始终具有较好的性能。
进一步地，本发明通过设置多个依次排列的放电模组，且每个放电模组 中的针状电极与对应的网状电极之间将产生电晕放电现象，从而可以使得风经过多个放电模组进行多次加速，实现风速的叠加，进而在获得较高的出风速度的情况下能够形成负压，进一步地增大进风量，从而进一步地提高了离子风发生装置的送风速度、送风量以及送风效率。
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
本发明实施例首先提供一种离子风发生装置，图1是根据本发明一个实施例的离子风发生装置的示意性结构图，图2是根据本发明一个实施例的离子风发生装置的一个放电模组的示意性结构分解图。参见图1至图2，本发明的离子风发生装置10包括用于产生离子风的至少一个放电模组100，每个放电模组100均包括壳体140、设置于壳体140内的网状电极110和分布在网状电极110一侧的多个针状电极120。需要强调的是，本发明实施例中所称的多个意指两个、三个或多于三个的更多个。具体地，网状电极110可以 为具有方形孔、菱形孔、圆形孔或其他形状通孔的金属网。针状电极120可以为金属材质的放电针，其具有放电尖端，该放电尖端可指向网状电极110的某一通孔的中心。
进一步地，网状电极110的一侧设有定型架150，定型架150固定在放电模组100的壳体140上，以使网状电极110始终保持在垂直于离子风发生装置10的送风方向的平面状态。也就是说，本发明通过定型架150对网状电极110进行位置和形状固定，能够避免网状电极110产生弯曲或变形，使其能够始终保持一平面结构，形成平面电极网。由于定型架150相比于细丝网状的网状电极110的结构强度大得多，其不会因外力作用而发生位移或变形，因此保证了每个针状电极120距网状电极110的距离均相同，即保证了针网的间距恒定不变，有效避免了因放电距离不等导致放电不均，从而产生摩擦打火、出现异味的现象，消除了安全隐患。
具体地，定型架150可采用硬度较大的塑料、橡胶或其他绝缘材料制成。
进一步地，离子风发生装置10的送风方向为其进深方向。具体地，离子风发生装置10可由后向前送风，即其产生的离子风的流动方向为由后向前。网状电极110在进深方向上位于针状电极120的前侧，以保证离子风发生装置10的出风方向为由后向前。定型架150在进深方向上位于网状电极110的前侧，由此既能够通过定型架150将网状电极110固定在壳体140上，又能够保证整个放电模组100的外形美观。壳体140仅具有上、下、左、右四个侧壁，其前侧和后侧均敞开。
在本发明的一些实施例中，网状电极110通过胶黏的方式固定在定型架150上。在一些替代性实施例中，网状电极110还可通过其他合适的方式固定在定型架150上。
在本发明的一些实施例中，每个放电模组100还包括用于固定多个针状电极120的针架130。针架130具有多个相互平行的导电杆131和多个相互平行的加强筋132，导电杆131和加强筋132交错设置，每个导电杆131与每个加强筋132的相交处均设有一个针状电极120。也即是，导电杆131和加强筋132的数量可以根据针状电极120的数量需求不同而产生变化，以保证每个针状电极120均能够通过导电杆131和加强筋132的双重作用得到固定。在针状电极120的数量确定后，导电杆131和加强筋132之间的间距和相对位置是恒定不变的，且导电杆131和加强筋132的结构强度相对较大， 几乎不会因外力作用发生位移或变形，因此能够可靠地保证每个针状电极120的相对位置恒定不变，保证了离子风发生装置始终具有较好的性能。
具体地，加强筋132和导电杆131可以一体成型，也可以通过胶黏、螺钉或其他合适的方式固定在一起。当加强筋132和导电杆131一体成型时，二者的材质相同；当加强筋132和导电杆131通过胶黏、螺钉或其他合适的方式固定在一起时，二者的材质可以相同，也可以不同。加强筋132可以采用硬度较高的塑料、橡胶等绝缘材料制成。
导电杆131优选为杆状或细长条状的PCB板。每个导电杆131均具有形成其外部的绝缘保护层和形成其内部的导电层，该导电层与分布在该导电杆上的针状电极120电连接。由此，可避免导电层裸露于外部，从而避免产生乱放电或打火的现象。进一步地，每个导电杆131的朝向网状电极110的侧面上均开设有多个用于安装针状电极120的针孔，该针孔的围绕针状电极120的周围设有通过焊接工艺填补的填充层。由此，可保证针状电极120与导电杆131内的导电层保持良好的电连接，同时又可严格地避免导电层裸露于外部，从而避免产生乱放电或打火的现象。具体地，针孔的尺寸可稍小于针状电极的尺寸，以使二者通过过盈配合的方式固定在一起。
在本发明的一些实施例中，导电杆131与加强筋132相互垂直，以使针架130不易变形，具有较强的结构稳定性和较高的结构强度，进一步可靠地保证了每个针状电极120的相对位置恒定不变。在一些替代性实施例中，导电杆131与加强筋132之间的夹角也可以为钝角或锐角，即导电杆131与加强筋132之间可围成多个菱形的格子。
进一步地，针架130还包括沿横向延伸的导电条133，每个导电杆131均与导电条133电连接，并由导电条133竖直向上延伸，每个加强筋132均沿横向延伸。具体地，导电条132与壳体140卡接，以使固定有多个针状电极120的导电条132和导电杆131固定在壳体140上。
在本发明的一些实施例中，每相邻两个导电杆131之间的距离均相同，每相邻两个加强筋132之间的距离均相同。由此，能够使得针状电极120的分布更加均匀，提高了离子风发生装置10送风的均匀性，从而提高了用户的舒适度体验。具体地，相邻两个导电杆131之间的距离与相邻两个加强筋132之间的距离可以相同，也可以不同。也就是说，多个导电杆131与多个加强筋132之间可围成多个长方形或正方形的格子。导电杆131和加强筋132 的数量和间距设置可根据针状电极120的数量需求不同而有所改变。
在本发明的一些实施例中，放电模组100的数量为多个，多个放电模组100沿离子风发生装置10的送风方向依次排列，且多个放电模组100并联连接或串联连接。具体地，在图1所示实施例中，放电模组100的数量可以为两个，两个放电模组100沿离子风发生装置10的送风方向依次排列。在另一些实施例中，放电模组100的数量还可以为三个或多于三个的更多个。
图3是根据本发明一个实施例的离子风发生装置的多个放电模组之间连接关系的示意性结构图。参见图3，每个放电模组100的针状电极120均与一正极性或负极性高压端子电连接，每个放电模组100的网状电极110均与接地端子电连接，以使多个放电模组100并联连接。也就是说，图3所示实施例的离子风发生装置10为并联式多级离子风送风装置。
图4是根据本发明另一个实施例的离子风发生装置的多个放电模组之间连接关系的示意性结构图。参见图4，位于离子风发生装置10的其中一端端部的放电模组100的针状电极120与一正极性或负极性高压端子电连接，位于另一端端部的放电模组100的网状电极110与接地端子电连接，从离子风发生装置10的其中一端向其另一端排列的除位于另一端端部的放电模组100之外的其余每个放电模组100的网状电极110均与相邻地位于其下游的放电模组100的针状电极120电连接，以使多个放电模组100串联连接。也就是说，图4所示实施例的离子风发生装置10为串联式多级离子风送风装置。
在图3和图4所示实施例中，每个放电模组100中的针状电极120与对应的网状电极110之间将产生电晕放电现象，从而可以使得风经过多个放电模组100进行多次加速，实现风速的叠加，进而在获得较高的出风速度的情况下能够形成负压，进一步地增大进风量，从而进一步地提高了离子风发生装置10的送风速度、送风量以及送风效率。
本发明实施例还提供一种空调室内机。图5和图6是根据本发明一个实施例的空调室内机的示意性结构图，图7是根据本发明一个实施例的空调室内机的示意性结构分解图。本发明的空调室内机1包括机壳30和至少一个上述任一实施例中所描述的离子风发生装置10。机壳30具有用于供气流流出的至少一个送风口31，该至少一个送风口31中的一个或多个送风口31处设有用于整流送风的开闭机构20。也即是，送风口31的数量可以为一个， 该送风口31处设有开闭机构20。或者，送风口31的数量为多个，仅有部分送风口31处有开闭机构20或全部送风口31处设有开闭机构20。
上述至少一个离子风发生装置10设置于机壳30内，以用于提供送往上述至少一个送风口31中的一个或多个送风口31的离子风。离子风发生装置10依靠电场力使空气中的粒子获得动能，从而形成离子风。相比于旋转类的送风组件(例如风机)来说，离子风发生装置10具有压损小、耗能低、噪音小等优势，从而在很大程度上减小了空调室内机运行时的噪音。
具体地，空调室内机1还包括设置于机壳30内的换热装置，换热装置配置成与流经其的空气进行热交换，以改变空气的温度。换热装置可以为平板式蒸发器、多折式蒸发器、多段式蒸发器或其他类型的蒸发器。空调室内机1可单独通过离子风发生装置10驱动送风，也可以与风机类组件相配合共同驱动送风。离子风发生装置10产生的离子风可以经过换热装置换热后送出，也可不经换热装置换热直接送出，以单独送风或与风机类组件驱动的气流相混合后送出。
在本发明的一些实施例中，具有开闭机构20的送风口31呈圆形。不具有开闭机构20的送风口1可以呈圆形、方形或其他合适的形状。每个开闭结构30均包括中央挡板21和多个曲形叶片22。
中央挡板21固定不动地设置于相应的一个送风口31的中央，其外周缘与相应的一个送风口31的内周缘之间形成出风区域。例如，上述中央挡板21可以为圆形，则相应的出风区域为环形。在本发明的一些替代性实施例中，上述中央挡板21可以为方形、椭圆形等其它形状。
多个曲形叶片22沿中央挡板21的周向依次设置，多个曲形叶片22配置成可以向中央挡板21的中心聚拢以至少部分地打开出风区域，并且可以完全聚拢收缩至中央挡板21的前侧或后侧。由此，可在空调室内机1停机时，使得多个曲形叶片22向送风口31边缘展开，并可以完全封闭出风区域，能够有效防止外部的灰尘和杂质进入风道内部，从而保证了空调室内机1的工作效果。在空调室内机1工作时，多个曲形叶片22向中央挡板21的中心聚拢收缩，以完全打开出风区域，以便于空调室内机1送风。
具体地，在一些实施例中，曲形叶片22的数量可以为6个，而且沿中央挡板21的周缘均匀地设置。在另外一些实施例中，叶片的数量还可以为6个以下或6个以上，具体可以根据叶片大小、中央挡板21的大小和送风口 31大小进行设定。优选地，参见图6，多个曲形叶片22可以完全聚拢收缩至中央挡板21的后侧，也就是说，多个曲形叶片22处于完全收拢状态时，中央挡板21可以遮蔽多个曲形叶片22，用户无法从送风口外部观察到曲形叶片22，使得送风口处的外形更加美观。更为重要的是，多个曲形叶片22可以完全收拢至中央挡板21的后侧，不占用额外的风道空间，提高了空调室内机1内部的空间利用率。参见图5，多个曲形叶片22还可以向背离中央挡板21中心的方向展开以至少部分地封闭出风区域。在图5所示实施例中，多个曲形叶片22可以展开至完全覆盖上述环形出风区域，以实现送风口的全面封闭。
图8和图9分别是根据本发明一个实施例的开闭结构的曲形叶片的不同方位示意性结构图。在本实施例中，曲形叶片22近似成月牙形，其具有一外轮廓边缘部和一内轮廓边缘部，外轮廓边缘部呈凸形，内轮廓边缘部呈凹形。内轮廓边缘部在多个曲形叶片22聚拢时朝向中央挡板21的中心设置，则相应地，外轮廓边缘部在多个曲形叶片22聚拢时可朝向送风口31的内周缘。外轮廓边缘部和内轮廓边缘部共同限定出曲形叶片22的根端和末端。
如图8-9所示，在本发明的一些实施例中，每个曲形叶片22的外轮廓边缘部包括：第一圆弧形区段221和第二圆弧形区段222。内轮廓边缘部包括：第三圆弧形区段223和第四圆弧形区段224。第一圆弧形区段221和第四圆弧形区段224朝向曲形叶片22的根端逐渐靠近，从而使得曲形叶片22的根端形成渐缩的曲形区域。第二圆弧形区段222和第三圆弧形区段223朝向曲形叶片22的末端逐渐靠近，从而使得曲形叶片22的末端同样形成渐缩的曲形区域。也就是说，第一圆弧形区段221和第四圆弧形区段224沿指向曲形叶片22的根端的方向逐渐靠近，以使曲形叶片22的根端形成渐缩的曲形区域；第二圆弧形区段222和第三圆弧形区段223沿指向曲形叶片22的末端的方向逐渐靠近，以使曲形叶片22的末端形成渐缩的曲形区域。
在本发明的一些优选地实施例中，第一圆弧形区段221的曲率与中央挡板21的外周缘的曲率相等。也就是说，当多个曲形叶片22完全聚拢至中央挡板21后侧时，多个曲形叶片22的第一圆弧形区段221与中央挡板21的外周缘重合。在多个曲形叶片22聚拢后，每个曲形叶片22的部分区域位于与该曲形叶片22的相邻的两个曲形叶片22之间。第二圆弧形区段222的曲率与送风口31的内周缘曲率相等。也就是说，当多个曲形叶片22完全展开 至覆盖出风区域时，多个曲形叶片22的第二圆弧形区段222与送风口31的内侧周缘重合。如此设计，多个曲形叶片22可以完全收拢至中央挡板21后侧或完全展开遮蔽出风区域，使得送风口31处的外形更加完整、美观。
另外，第三圆弧形区段223的曲率和长度与第一圆弧形区段221的曲率和长度均相等。在本实施例中，在多个曲形叶片22完全展开至覆盖出风区域时，相邻两个曲形叶片22的第一圆弧形区段221和第三圆弧形区段刚好拼合在一起，使得多个曲形叶片22能够完整地覆盖出风区域，同时相邻曲形叶片22之间尽可能不发生交叠，以充分利用曲形叶片的大小，使得送风口处的外形更加完整、美观。
在本发明的一些实施例中，为了便于多个曲形叶片22的聚拢和展开，每个曲形叶片22优选地绕其根端可转动地设置于中央挡板21的前侧或后侧。而且，在多个曲形叶片22聚拢后，每个曲形叶片22的部分区域位于与该曲形叶片的相邻的两个曲形叶片22之间。
进一步地，第一圆弧形区段221上还具有从邻近曲形叶片22根端向远离根端方向渐高的导向凸缘225，以在多个曲形叶片22收缩或扩展运动时，在室内机前后方向上对多个曲形叶片22进行导向，以便于多个曲形叶片22可至少部分重叠。这样设置是因为多个曲形叶片22在收拢的过程当中，相邻的曲形叶片22可能会发生机械干涉。上述导向凸缘225靠近根端的位置较低，远离根端的位置较高，在相邻的曲形叶片22收拢至相互叠加时，导向凸缘225可以引导相邻叶片朝向后侧略微移动，以使得相邻的曲形叶片22在开闭结构20的前后方向上错开，以防止机械干涉。
在图7中，X轴正方向指向空调室内机的前侧，Y轴正方向指向室内机的右侧，Z轴正方向指向室内机的上方。在空调室内机1的进深方向上，送风口31位于机壳30的前侧，至少部分送风口31的后侧均设有一导风结构50。优选地，具有开闭机构20的圆形送风口31处设有导风机构50。
图10是根据本发明一个实施例的空调室内机的导风结构的正面示意图。参见图10，每个导风结构50包括：转动环53和两个摆叶组件。
转动环53设置于机壳30内部且正对相应的一个送风口31设置，转动环53配置成可控地绕其中心轴线转动。转动环53的内周缘可与送风口31的内周缘在空调室内机1的上下及左右方向上重合，即转动环53的内周缘设置于送风口31的内周缘的后侧。
两个摆叶组件可间隔设置于转动环53上，每个摆叶组件包括摆叶驱动机构和多片摆叶54，多片摆叶54位于转动环的内侧，且每片摆叶54的根部均具有一自转轴541，自转轴541的末端可穿过一圆孔。摆叶驱动机构配置成驱动多片摆叶54绕各自的自转轴541同步自转。且两个摆叶组件的摆叶54也关于转动环53的上述一条直径对称设置，并且相互对称的两片摆叶54的自转轴541在同一条直线上。摆叶54大小可以根据出风区域的大小进行设定。
在本发明的一些实施例中，每个摆叶驱动机构可跟随转动环53旋转，且包括：曲形连杆、多个摇杆、曲柄以及连杆电机。
在本实施例中，转动环53的转动范围优选为0至90°。导风结构50的工作原理为：转动环53先转动至预设位置，以带动多片摆叶54的自转轴541运动到相对于水平面处于特定角度的位置，再根据用户需要调节摆叶54的自转角度。具体地，当用户需要空调室内机1上下方向出风时，转动环53先转动至0°。此时，自转轴541处于水平方向的位置，如图6中空调室内机1的右侧送风口31所示，此时，再驱动两个曲形连杆上下运动，带动多片摆叶54上下翻转。当多片摆叶54上翻时，送风口31则向上出风；当多片摆叶54下翻时，送风口31则向下出风。当用户需要室内机左右方向出风时，转动环53先转动至90°。此时，自转轴541处于竖直方向，如图6所示空调室内机1的左侧送风口，此时，再驱动两个曲形连杆运动，带动多片摆叶54左右翻转。当多片摆叶54左翻时，送风口31则向左出风；当多片摆叶54右翻时，送风口31则向右出风。
由此可见，本发明导风结构50的摆叶54可以绕其自转轴541自转，还可以跟随转动环绕转动环53的中心公转。在空调室内机1的使用过程中，用户可以先调节转动环53旋转，确定送风口31的扫风方向，例如上下扫风、左右扫风、斜45°扫风，再调节摆叶54自转进行扫风。或者，在转动环53转动的过程中，同时进行扫风，以可能地吹出自然风。本发明的摆叶54具有更加多样的摆动角度，用户可以更加自由地调节送风口的送风角度。
在本发明的一些实施例中，参见图10，设有开闭机构50的送风口31的数量为多个，空调室内机1还包括与设有开闭机构50的送风口31一一对应设置的多个轴流风机60。具体地，离子风发生装置10的数量为一个，轴流风机60的数量为两个，两个轴流风机60分别设置在离子风发生装置10 的横向两侧。
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。
