Description

壁挂式空调室内机 技术领域
本发明涉及空调技术领域，特别是涉及一种壁挂式空调室内机。
背景技术
因冷空气密度较大具有下降趋势，热空气密度较小具有上升趋势，壁挂式空调室内机在制热时希望让风更大角度地向下吹，在制冷时希望让风更大角度地向上吹。
传统的壁挂式空调室内机在壳体底部前侧开设出风口，利用导风板实现上吹风和下吹风。但出风口的位置、朝向均固定，导风板的转动角度也受限，无法实现既能大角度地上吹风，又能大角度下吹风。如果吹风角度不够大，可能会出现风直吹人体的问题，使人体感觉不舒适。
发明内容
本发明的一个目的是要克服现有技术存在的至少一个缺陷，提供一种壁挂式空调室内机，增大上吹风和下吹风的角度，避免风直吹人体的问题。
特别地，本发明提供了一种壁挂式空调室内机，其包括：
壳体，其后侧具有进风口，前侧具有上下排列的上出风口和下出风口；
蒸发器，设置在壳体内；
至少一个风机，设置在壳体内，用于促使室内空气从进风口进入壳体，与蒸发器换热形成热交换风后，再从上出风口和/或下出风口吹出；
上挡板，配置成受控地打开/关闭上出风口；和
下挡板，配置成受控地打开/关闭下出风口。
可选地，上出风口和下出风口之间的壳体部分为前面板；上挡板可受控地在完全隐藏在前面板后侧的位置和完全封闭上出风口的位置之间滑动，以便调节上出风口的出风面积；且下挡板可受控地在完全隐藏在前面板后侧的位置和完全封闭下出风口的位置之间滑动，以便调节下出风口的出风面积。
可选地，上挡板上设置有第一齿条，前面板上设置有第一步进电机，第一步进电机上安装有第一齿轮，第一齿轮与第一齿条啮合，以便带动上挡板滑动；且下挡板上设置有第二齿条，前面板上设置有第二步进电机，第二步 进电机上安装有第二齿轮，第二齿轮与第二齿条啮合，以便带动下挡板滑动。
可选地，前面板为百叶窗结构，以便在打开时允许热交换风通过前面板向前吹向室内。
可选地，上出风口朝向前下方，下出风口朝向前下方。
可选地，上挡板、下挡板以及前面板均为中部前凸的弧形结构。
可选地，风机的数量为两个，两个风机分别为轴线沿左右方向延伸且沿上下方向排列的上贯流风机和下贯流风机。
可选地，两个风机的前侧设置有分隔部件；分隔部件的上侧表面与壳体上侧内壁构成上风道，以将上贯流风机的风引向上出风口；且分隔部件的下侧表面与壳体下侧内壁构成下风道，以将下贯流风机的风引向下出风口。
可选地，分隔部件的前侧表面与壳体前侧内壁构成连接上风道和下风道的中间风道。
可选地，蒸发器设置在风机与进风口之间。
本发明的壁挂式空调室内机相比于现有技术仅仅设置一个出风口的方案，设置有上出风口用于向上吹风，设置下出风口用于向下吹风，增大了上吹风和下吹风的角度，甚至能够实现垂直向上和垂直向下吹风，完全避免了风直吹人体的问题。上出风口和下出风口均可受控地开闭，用户可根据需要仅开启上出风口、仅开启下出风口或同时开启上出风口和下出风口，极大丰富了送风模式。
进一步地，本发明的壁挂式空调室内机通过使前面板为百叶窗结构，能够使得前面板向前吹风。百叶窗的多个格栅转动时，还能够改变出风方向。如此，百叶窗与上、下出风口一起，实现了上中下三个方向全面出风，增大了送风角度，提升了制冷/制热速度。并且进一步丰富了送风模式。
进一步地，本发明的壁挂式空调室内机设置两个贯流风机，分别用于与上出风口和下出风口匹配，并设置分隔部件形成上风道、下风道和中间风道，使风机距离出风口的距离更短，送风效率更高。并且，相比于设置一个功率较大风机的方案，本发明设置两个风机，两个风机的功率相对较小。如此，在仅开启一个出风口时，仅需开启一个风机即可，如此能够使风机的运行功率损耗较小，使其更加节能。
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
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是本发明一个实施例的壁挂式空调室内机的示意性剖视图；
图2是图1所示壁挂式空调室内机关闭上出风口和下出风口后的示意图；
图3是图1所示壁挂式空调室内机仅打开下出风口时的示意图；

图7是图5所示壁挂式空调室内机打开上出风口时的示意图。
具体实施方式
下面参照图1至图7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。
如图1和图2所示，本发明实施例的壁挂式空调室内机一般性地可包括壳体10、蒸发器20、至少一个风机、上挡板50和下挡板60。该壁挂式空调室内机与空调室外机配合使用，采用蒸气压缩制冷循环系统实现对室内环境的制冷/制热。
壳体10限定有容纳空间，以容纳壁挂式空调室内机的各个部件。壳体10的后侧具有进风口101，前侧具有上下排列的上出风口102和下出风口103。蒸发器20设置在壳体10内，可为翅片式蒸发器。风机设置在壳体10内，用于促使室内空气从进风口101进入壳体10，与蒸发器20换热形成热交换风，再使热交换封从上出风口102和/或下出风口103吹出。蒸发器20可设置在风机与进风口101之间，以便于风机的风更顺畅地吹向出风口。当然，也可使风机设置在蒸发器20与进风口101之间。上挡板50配置成受控 地打开/关闭上出风口102，下挡板60配置成受控地打开/关闭下出风口103。
现有结构的壁挂式空调室内机仅在壳体10底部开设向前的一个出风口，不利于向上送风，更是无法实现向上垂直送风。而本发明实施例中上出风口102用于向上吹风，设置下出风口103用于向下吹风，增大了上吹风和下吹风的角度，避免了风直吹人体的问题。优选地，使上出风口102朝向前下方开设，使下出风口103朝向前下方开设，更加便于实现垂直向上和垂直向下吹风。
并且，本发明实施例中，上出风口102和下出风口103均可受控地开闭，用户可根据需要仅开启上出风口102、仅开启下出风口103或同时开启上出风口102和下出风口103，如此极大丰富了送风模式。例如图4，在空调制冷时，可仅开启上出风口102，关闭下出风口103，便于冷风上吹，冷风再向下流动使整个室内空间温度更加平衡。例如图3，在空调制热时，可仅开启下出风口103，关闭上出风口102，便于热风下吹，使热风向上流动使整个室内空间温度更加平衡。或者，无论在制冷或制热时，可同时开启两个出风口，加大室内机的出风角度，以利于室内迅速地实现制冷或制热。
在一些实施例中，上出风口102和所述下出风口103之间的壳体部分为前面板13。上挡板50可受控地在完全隐藏在前面板13后侧的位置和完全封闭上出风口102的位置之间滑动，以便调节上出风口102的出风面积。例如，可使上挡板50完全打开上出风口102、完全封闭上出风口102或将上出风口102打开至一定开度，如打开至30％、50％等。同样地，下挡板60可受控地在完全隐藏在前面板13后侧的位置和完全封闭下出风口103的位置之间滑动，以便调节下出风口103的出风面积。
具体地，参见附图2，在一些实施例中，可采用两套电动齿轮齿条机构驱动上挡板50和下挡板60移动。在上挡板50上设置有第一齿条51，在前面板13上设置有第一步进电机52，第一步进电机52上安装有第一齿轮53，第一齿轮53与第一齿条51啮合。第一步进电机52转动带动第一齿轮53转动，第一齿轮53转动带动第一齿条51平移，以带动上挡板50滑动。同样地，在下挡板60上设置有第二齿条61，前面板13上设置有第二步进电机62，第二步进电机62上安装有第二齿轮63，第二齿轮63与第二齿条61啮合，以便带动下挡板60滑动。
在一些实施例中，上挡板50、下挡板60以及前面板13均为中部前凸的 弧形结构，以更加利于上挡板50和下挡板60的伸缩，同时也便于使上出风口102朝前上方设置，使下出风口103朝前下方设置，也是壁挂式空调室内机的外观更加美观。
在一些实施例中，如图5所示，可使前面板13为百叶窗结构，其由多个相互平行设置的格栅条131构成，相邻格栅条131之间形成由通风间隙，以便在打开时允许热交换风通过前面板13处向前吹向室内。
可使多个格栅条无法转动，始终保持在通风状态，以便在壁挂式空调室内机开启时一直能够通过前面板13向前送风。
也可使多个格栅条能够同步转动，以便改变风向。如图5所示，多个格栅条131均沿水平方向延伸，其同步转动时，能够在上下方向调节风向。多个格栅条131上下往复转动时，还能实现上下摆风。当然，也可使多个格栅条沿竖直方向延伸，以便实现左右风向的调节以及实现左右摆风。
本实施例通过使前面板13能够向前吹风，使其与上出风口102、下出风口103一起，实现了上中下三个方向全面出风，增大了送风角度，提升了制冷/制热速度。并且进一步丰富了送风模式。例如，至少包括以下几种送风模式：如图5所示仅向前送风，出风口和下出风口103关闭；如图6所示向前送风结合向下送风；如图7所示向前送风结合向上送风。
在一些实施例中，如图1，风机的数量为两个，两个风机优选分别为轴线沿左右方向延伸且沿上下方向排列的上贯流风机41和下贯流风机42。并且，使两个风机的前侧设置有分隔部件30。分隔部件30的上侧表面31与壳体10上侧内壁11构成上风道91，以将上贯流风机41的风引向上出风口102。且分隔部件30的下侧表面32与壳体10下侧内壁12构成下风道92，以将下贯流风机42的风引向下出风口103。
优选地，可使分隔部件30的前侧表面33与壳体10前侧内壁(即前面板13)构成连接上风道91和下风道92的中间风道93。如此，在仅开启下出风口103时，如图3，可使上贯流风机41的风经中间风道93汇入下风道92。在仅开启上出风口102时，如图4，可使下贯流风机42的风经中间风道93汇入下风道92。
当然，在一些可选的结构中，也可使分隔部件30将上风道91和下风道92完全隔开，使上出风口102的风完全来源于上贯流风机41，使下出风口103的风完全来源于下贯流风机42。
对于同样规格的空调室内机，可如本实施例所述设置两个功率较小的贯流风机，也可仅仅设置一个功率较大的贯流风机(功率大致等于两个小的贯流风机之和)。但是，在一些情况下，如制冷/制热需求较低时，风量要求低，开启大功率的贯流风机使其转速较小，风机在低转速运行效率较低。因此，本实施例采用两个功率较小的贯流风机代替一个较大的贯流风机，能够在风量要求低时仅开启一个贯流风机即可，使其转速更高，运行效率更高。此外，两个贯流风机分别与上出风口102和下出风口103匹配，并设置分隔部件30形成上风道91、下风道92和中间风道93，使风机距离出风口的距离更短，送风效率更高。
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。
