Description

壁挂式空调室内机 技术领域
本发明涉及空调技术领域，特别涉及一种壁挂式空调室内机。
背景技术
目前，传统的壁挂式空调室内机多为上进风、下出风的气流循环方式，且用于驱动气流循环的装置多为贯流风扇。气流沿垂直于贯流风扇的轴向方向进入贯流风扇的内部，并两次穿过贯流风扇的叶轮，在叶轮内部，气流被强制弯折，使得气流的压力损失较大，风量较低，整机运行时的噪音较大。
为了避免采用贯流风扇驱动气流循环带来的一系列问题，现有技术中的一些壁挂式空调室内机将贯流风扇替换成离心风扇。虽然这种壁挂式空调室内机能够在一定程度上解决上述风量较低、气流压损较大的问题，但效果却不是特别明显，并且丝毫不能解决噪音较大的问题。像噪音大、风量小这种用户能够通过直观感受体验到的缺陷严重影响了壁挂式空调室内机的整体使用性能，并且大大限制了壁挂式空调室内机的使用范围。
为了减小噪音，目前公开的一些专利文献中所涉及的壁挂式空调室内机直接将风机简单地替换成离子风装置，然而，其离子风装置所产生的离子风风速极其有限，替换后的壁挂式空调室内机的风速大幅度地减低，几乎不能满足用户最基本的使用需求。也正是由于现有的这种技术方案存在诸多缺陷和不可实践性，截止目前，利用离子风送风的技术还仅停留在最基础的理论层面上。
发明内容
本发明的一个目的旨在克服现有技术中的至少一个缺陷，提供一种风量较大且噪音较小的壁挂式空调室内机。
本发明的另一个目的是扩大壁挂式空调室内机的送风范围，提高空调室内机送风的均衡性。
本发明的又一个目的是提高壁挂式空调室内机送风的柔和性和舒适度。
为了实现上述目的，本发明提供一种壁挂式空调室内机，包括：
壳体，后侧具有进风口，前侧具有至少一个圆形出风口；
换热装置，设置在壳体内；和
至少一个送风装置，与圆形出风口一一对应，每个送风装置包括：
轴流风机，与圆形出风口同轴地设置于壳体内，用于将与换热装置换热后气流吹向圆形出风口；
导风格栅，其具有沿圆形出风口边缘延伸且可绕圆形出风口的中心轴旋转的圆框以及长度方向相互平行的多个格栅条，格栅条的两端铰接于圆框，且枢转轴线平行于其长度方向，以便通过旋转圆框和/或同步摆动多个格栅条来调节圆形出风口的出风方向。
可选地，每个送风装置还包括：弧形齿条，与圆框同轴地设置在圆框边缘；齿轮，与弧形齿条啮合；和第一电机，安装于壳体，用于驱动齿轮转动，以带动弧形齿条转动，进而带动圆框旋转。
可选地，每个送风装置还包括：连杆，其长度方向的不同部位与分别与格栅条铰接；和第二电机，安装于圆框，用于驱动一个格栅条枢转，以使该格栅条转动时，带动连杆平移，进而带动其余的格栅条摆动。
可选地，第二电机配置成驱动最接近圆框中心的格栅条枢转。
可选地，换热装置为板状蒸发器，且设置在轴流风机的后侧。
可选地，壁挂式空调室内机，还包括离子风出风口，位于壳体前侧；和离子风发生装置，配置成受控地利用电场力促使壳体内的气流从离子风出风口吹出壳体。
可选地，圆形出风口的数量为两个，两个圆形出风口沿壳体的横向方向排列，离子风出风口位于两个圆形出风口之间；且送风装置的数量为两个，两个送风装置的轴流风机沿壳体的横向方向排列，离子风发生装置位于两个轴流风机之间。
可选地，离子风发生装置包括至少一个放电模组，每个放电模组均具有金属网和位于金属网内侧并呈阵列排布的多个放电针，其中每个放电针的针尖与金属网的距离L设置成使其满足：L＝aL1，其中，a为范围在0.7～1.3之间的任一常数，L1为使得金属网的风速中心点处的离子风风速达到最大风速Vmax时放电针的针尖与金属网之间的距离，金属网的风速中心点为放电针的针尖在金属网上的投影点。
可选地，相邻两个放电针的针尖之间的距离R设置成使其满足：R＝aR1，其中，R1为风速达到最大风速Vmax的b倍的风速测量点与风速中心点之 间的距离，b为范围在0.3～0.7之间的任一常数。
可选地，离子风发生装置包括依次排列且并联或串联连接的多个放电模组，每个放电模组均具有金属网和位于金属网内侧并呈阵列排布的多个放电针；且相邻两个放电模组的放电针直对布置或错位布置。
本发明的壁挂式空调室内机通过轴流风机使气流由后向前地贯穿壳体，缩短了气流流动距离，减小了风压损失和能量损失，提高了壁挂式空调室内机的运行效率。此外，导风格栅包括可旋转的圆框以及可摆动的多个格栅条，通过圆框的旋转以及格栅条的摆动的组合运动，能够实现上下左右四个方向送风，大幅增加送风范围。
进一步地，本发明的壁挂式空调室内机中，离子风发生装置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，离子风发生装置具有压损小、耗能低、噪音小等优势。相比于全部使用旋转类送风组件的方案，本发明采用离子风发生装置和轴流风机组合送风，既能够满足大风量送风的要求，又能够大幅度地降低其送风时的噪音。
进一步地，本发明壁挂式空调室内机通过合理设计离子风发生装置的放电针与金属网的空间位置关系，并同时合理布局多个放电针相互之间的位置关系，可使得离子风发生装置能够产生均匀的、较大风量的离子风，从而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。
附图说明

具体实施方式
下面参照图1至图9来描述本发明实施例的壁挂式空调室内机，本发明实施例的描述中，“前”、“后”、“上”、“下”、“顶”、“底”、“内”、“外”“横向”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，仅为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、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。
图1是根据本发明一个实施例的壁挂式空调室内机的结构示意图；图2是图1所示壁挂式空调室内机的分解示意图。如图1至图2所示，本发明实施例提供了一种壁挂式空调室内机，其一般性地可包括壳体10、换热装置90以及至少一个送风装置100。壳体10限定有容纳空间，壳体10的后侧设置有进风口11，前侧具有至少一个圆形出风口12。送风装置100的数量与圆形出风口12的数量相同，以与圆形出风口12一一对应。每个送风装置100包括轴流风机30以及导风格栅50。其中，轴流风机30与圆形出风口12同轴地设置于壳体10内(轴线沿前后方向设置)，用于将与换热装置90换热后气流吹向圆形出风口12。导风格栅50具有沿圆形出风口12边缘延伸且可绕圆形出风口12的中心轴旋转的圆框52以及长度方向相互平行的多个格栅条54，格栅条54的两端铰接于圆框52，以能够绕一轴线枢转，且枢转轴线平行于其长度方向，以便通过旋转圆框52和/或同步摆动多个格栅条54来调节圆形出风口12的出风方向。
本发明实施例中，室内气流经进风口11进入壳体10内，向前流动与换热装置90换热后，被轴流风机30向前加速输送至圆形出风口12吹回室内，其出风方向被多个格栅条54引导。因气流由后向前贯穿壁挂式空调室内机， 缩短了气流流动的距离，减小了风压损失和能量损失，提高了壁挂式空调室内机的整机的运行效率。
在一些实施例中，如图2所示，壳体10包括前后均敞开的中壳16、分别用于封盖中壳16前后开口的前面板18以及后盖板19。其中，前面板18上开设有前述的圆形出风口12。后盖板19上设置有进风口11，进风口11也可设置为进风栅格结构。
在一些实施例中，如图1至图2所示，壁挂式空调室内机为横向(左右方向)较长，纵深较短的长条状结构，此时圆形出风口12的数量优选为两个，两个圆形出风口12沿壳体10的横向方向排列。当然，与圆形出风口12相对应的，送风装置100的数量同样为两个。
在一些实施例中，如图2所示，换热装置90为板状蒸发器。可使板状蒸发器设置在轴流风机30的后侧，并将轴流风机30设置在壳体10的前面板18的后侧。具体可在前面板30的后侧安装一个圆形框架60，圆形框架60与圆框52同轴设置，圆框52可旋转地安装于圆形框架60处。轴流风机30开启后，将风向前吹送，后侧形成负压环境将换热装置90处的空气向前吸入。当然，在一些替代性的实施例中，也可使换热装置90设置在轴流风机30的前侧。
图3是图2中的导风格栅和圆形框架的结构示意图；图4是导风格栅的另一角度示意图；图5是导风格栅的侧视图。
在一些实施例中，如图3至图5所示，每个送风装置100还包括弧形齿条524、齿轮56和第一电机58。其中，弧形齿条524与圆框52同轴地设置在圆框52的边缘(可与其一体成型)，因格栅条54也能够枢转，因此只需使弧形齿条524覆盖圆框52的1/4个圆周，使圆框52能够旋转90°，既能够实现上下左右四个方向的送风。齿轮56用于与弧形齿条524啮合。第一电机58安装于壳体10，用于驱动齿轮56转动，以带动弧形齿条524转动，进而带动圆框52旋转。具体地，第一电机58可安装于圆形框架60上，圆形框架600可包括内径较大的前段62和内径较小的后段64，以形成罩壳状，便于将圆框52容纳其中。
如图4和图5所示，每个送风装置100还包括连杆55以及第二电机53。其中，连杆55的长度方向的不同部位与分别与格栅条54铰接(图5中，铰接轴42伸入铰接孔551中)，第二电机53安装于圆框52，用于驱动一个格 栅条54枢转(图5中，第二电机53被隐藏，其带动中间的格栅条54围绕枢转轴541转动)，以使该格栅条54转动时，带动连杆52平移，进而带动其余的格栅条54摆动(图5用箭头示意了连杆55的移动方向和格栅条54的摆动方向)。
优选使第二电机53配置成驱动最接近圆框52中心的格栅条54枢转，以使各个格栅条54的受力更加均匀。
本发明实施例中，圆框52的旋转以及格栅条54的摆动相组合，实现上下左右四个方向的交替送风，大幅增加送风范围。此外，在壁挂式空调室内机关机时，还可使格栅条54能够同步枢转至一位置，能够封闭圆形出风口12，避免灰尘和杂质进入在壳体10的内部。
在一些实施例中，如图2所示，壁挂式空调室内机还包括离子风出风口14以及离子风发生装置41。离子风出风口14位于壳体10前侧，具体设置在前面板18上，离子风发生装置41配置成受控地利用电场力促使壳体10内的气流从离子风出风口14吹出壳体10。离子风发生装置41产生流动的离子风气流的原理是本领域技术人员比较习知和容易获得的，因此这里不再赘述。离子风出风口14可为由多个微孔组成的孔组结构。
前文已述，圆形出风口12以及送风装置100的数量均优选为两个。此时可使离子风出风口14位于两个圆形出风口12之间，使离子风发生装置41位于两个轴流风机30之间。也即是两个轴流风机30和离子风发生装置41并联设置。由此，可以实现线、面上的均匀出风，避免局部区域风速过大、局部区域风速过小的问题，从而扩大了壁挂式空调室内机的送风范围和送风量，并使壁挂式空调室内机送出的气流更加均衡。在一些替代性的实施例中，也可使离子风发生装置41设置在轴流风机30的前侧或后侧，即串联设置。
在本发明的一些实施例中，壁挂式空调室内机还包括控制装置，用于控制上述轴流风机30单独启动运行、控制上述至离子风发生装置41单独启动运行或控制轴流风机30和离子风发生装置41同时启动运行。以使壁挂式空调室内机工作于仅通过轴流风机30驱动送风的速冷/速热模式或仅通过离子风发生装置41驱动送风的静音模式或通过轴流风机30和离子风发生装置41同时驱动送风的大风量模式。也就是说，本发明能够通过控制装置对离子风发生装置41和轴流风机30的启停进行控制，从而使壁挂式空调室内机至少具有速冷/速热、静音和大风量三种工作模式，从而满足了不同用户或同一用 户在不同情况下的多种使用需求，提高了用户的使用体验。控制装置可通过有线或无线的方式与上述轴流风机30和离子风发生装置41信号连接。
具体地，在静音模式下，所有的轴流风机30不启动运行，壁挂式空调室内机仅通过所有的离子风发生装置41向离子风出风口14驱动送风，轴流风机30对气流不产生任何的驱动作用。由于本发明的离子风发生装置41运行时的工作噪音接近甚至低于室内的背景噪音，因此大幅度地降低了壁挂式空调室内机运行时的整体噪音，解决了超低静音送风的行业难题。此种模式适用于医疗、儿童监护等使用环境、以及壁挂式空调室内机运行一段时间以后的情形。在速冷/速热模式下，所有的离子风发生装置41不启动运行，壁挂式空调室内机仅通过所有的轴流风机30向圆形出风口12驱动送风，离子风发生装置41不对气流产生任何的驱动作用。由于轴流风机30的送风量相对较大、制冷效率或制热效率相对较高，因此能够快速地缓解室内的温度。此种模式适用于壁挂式空调室内机刚开始启动运行的情形、或其他需要迅速制冷或制热的情形。在大风量模式下，离子风发生装置41和轴流风机30可受控地同时启动运行，以同时向圆形出风口12以及离子风出风口14送风，也即是气流分别经离子风发生装置41和轴流风机30的驱动作用后送出。因此，此种模式适用于对风量和风速有较高要求的情形、更加快速制冷或快速制热的情形、以及其他对风速有较高要求的情形。
在本发明的一些实施例中，可使与每个轴流风机30相对应的圆形出风口12处的导风格栅50在速冷/速热模式和大风量模式下受控地打开出风口12、在静音模式下受控地关闭该圆形出风口12。图6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。在本发明的一些实施例中，参见图6，每个离子风发生装置41均包括至少一个放电模组410。每个放电模组410均具有金属网411和位于金属网411后侧并呈阵列排布的多个放电针412。金属网411在垂直于前后方向的平面内延伸。金属网411上均匀分布有圆形孔、方形孔、菱形孔或其他形状的通孔。放电针412具有放电尖端，该放电尖端可直向金属网411的某一通孔的中心。放电针412和金属网411上分别施加正负高压电极，放电针412相当于产生电晕放电的放射极，金属网411相当于接收极。
也就是说，每个放电模组410所产生的离子风的流向均为从后向前，多个放电针412与金属网411的排布方向与离子风的流向相同。
图7是根据本发明一个实施例的放电模组的示意性剖视图。参见图7，为了提高离子风发生装置的送风速度，本发明的设计人进行了大量的风速测量实验，实验结果发现，将每个放电针412的针尖与金属网411的距离L设置成使其满足L＝aL1(其中，a为范围在0.7～1.3之间的任一常数，即a可取值为0.7、0.8、0.9、1.0、1.1、1.2或1.3，L1为使得金属网411的风速中心点处的离子风风速达到最大风速Vmax时放电针412的针尖与金属网411之间的距离，金属网411的风速中心点为放电针412的针尖在金属网411上的投影点)的关系后，一方面，离子风发生装置41所产生的离子风风速能够更好地满足用户正常的使用需求，另一方面，还可确保放电针412在金属网411产生有效离子风的区域内能够部分重叠以达到无影灯的投射的效果，从而使得金属网411的离子风分布更加均匀。
为了提高离子风发生装置的送风量，本发明的设计人进行了大量的针尖投影半径测量的实验，实验结果发现，将相邻两个放电针412的针尖之间的距离R设置成使其满足R＝aR1(其中，R1为风速达到最大风速Vmax的b倍的风速测量点与风速中心点之间的距离，b为范围在0.3～0.7之间的任一常数，即b可取值为0.3、0.4、0.5、0.6或0.7，a的取值与上述相同)的关系后，离子风发生装置41所产生的离子风风量能够更好地满足用户正常的使用需求。同时，对相邻两个放电针412之间的距离进行特别设计后，既能够避免相邻两个放电针412之间因距离太近而发生风速相互抵消，又能够避免两个放电针412之间的距离太远而导致风量减少以及风量分布不均匀。
由此可见，本发明通过合理设计放电针412与金属网411的空间位置关系，并同时合理布局多个放电针412相互之间的位置关系，可使得离子风发生装置41能够产生均匀的、较大风量的离子风，从而提高了离子风发生装置41的送风速度、送风量以及送风效率。
在本发明的一些实施例中，每个离子风发生装置41均包括沿前后方向依次排列、且并联或串联连接的多个放电模组410，每个放电模组410均具有金属网411和位于金属网411后侧并呈阵列排布的多个放电针412。由此，每个放电模组410中的放电针412与对应的金属网411之间将产生电晕放电现象，从而可使得离子风经过多个放电模组410进行多次加速，可以实现风速的叠加，以获得较高的出风速度。并且在高速出风作用下能够形成负压，进一步的增大进风量、提高多级离子送风模块的送风速度、送风量以及送风 效率。
在本发明的一些实施例中，相邻两个放电模组410的放电针412直对布置，也就是说，每相邻两个放电模组的放电针412在离子风发生装置的出风面内的投影重合。由此，每个放电针412的尖端所对应的区域会产生较大较强的电场，因此该区域会产生局部风速较高的离子风，该离子风吹到用户身上会另用户具有较强的风感。换句话说，此种布置方式可在金属网411的每个风速中心点附近获得局部的较大风速，以提升壁挂式空调室内机单独由离子风发生装置驱动送风时的风感。
在本发明的一些替代性实施例中，相邻两个放电模组410的放电针412错位布置。图8所示实施例为其中一种错位布置方式，其中OZ轴表示高度方向，OY轴表示横向。为了便于理解，将相邻两个放电模组410的结构分别以实线和虚线示出。该错位布置方式为：每相邻两个放电模组的放电针412在横向上错位布置，且每相邻两个放电模组的相应放电针412在离子风发生装置10的出风面内的投影处于同一水平线上(即每相邻两个放电模组的放电针412错位布置，但相应放电针412所处的高度相同)。由此，在水平方向上的若干个线性区域内可产生较为均匀的柔和风，多个放电模组的叠加又可在该线性区域内形成较大较强的电场，因此该线性区域内的离子风风速相对较高。进一步地，多个放电模组的放电针412在水平面内所形成的每组彼此相邻的三个放电针投影均形成等腰三角形，以确保离子风发生装置产生的离子风分布比较均匀。
图9所示实施例为另一种错位布置方式，其中OZ轴表示高度方向，OY轴表示横向。为了便于理解，将相邻两个放电模组410的结构分别以实线和虚线示出。该另一种错位布置方式为：每相邻两个放电模组的放电针412在横向以及竖直方向上均错位布置。由此，离子风发生装置产生的离子风可在其出风面内均匀分布，以在低电压、低电场强度、低功率的情况下实现柔和、均匀和大风量的送风。也就是说，每相邻的两个放电模组410的放电针412均相互错位，可填补每个放电模组410的多个放电针412之间的间隙。由此，可在金属网411的整个区域内形成比较均匀的离子风，提升了整体的送风量。进一步地，多个放电模组的放电针412在离子风发生装置的出风面内所形成的每组彼此相邻的三个放电针投影均形成等边三角形，以确保离子风发生装置产生的离子风分布更加均匀。
在本发明的一些实施例中，参见图6，每个放电模组410还包括壳体416、具有多个金属导电片414的金属导电条413以及与金属导电条413电连接、并垂直于金属导电条413的至少一个PCB多层板415。PCB多层板415具有前后两层绝缘保护层以及位于两层绝缘保护层之间的导电层，该导电层与金属导电片414电连接。壳体416的底壁上开设有卡扣4161，金属导电条413的金属导电片414扣合在壳体416的卡扣4161中。
PCB多层板415的数量可以为一个，其大致呈长方形；或者PCB多层板415的数量可以为多个，每个PCB多层板415均呈垂直于金属导电条413延伸的细长条状。
多个放电针412均匀地分布在至少一个PCB多层板415的朝向金属网411的外侧。具体地，每个PCB多层板415的外侧表面上均开设有若干个用于安装放电针412的针孔。针孔的孔径稍小于放电针412的直径，以使针孔与放电针412过盈配合。插入放电针412的针孔周围设有通过焊接工艺填补的填充层，也即是针孔的围绕放电针412的周围设有通过焊接工艺填补的填充层，以保证放电针412与PCB多层板415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。
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。
