Description

壁挂式空调室内机 技术领域
本发明涉及空气调节技术，特别是涉及一种壁挂式空调室内机。
背景技术
现有技术中，为了调节空调室内机的送风方向，一般是在出风口处设置可以上下摆动的导风板。但是上述这种调节方式具有一定的缺陷。虽然用户可以通过调节导风板的角度来改变气流方向，但是这种调节手段可能带来其他影响，例如导风板在向上摆动的过程中，导风板正对出风口的面积越来越大，导致在调节送风方向时降低了出风量，影响空调的调温效果。
因此，在不影响空调的调温效果的前提下，如何实现调节送风角度成为本领域技术人员亟待解决的技术问题。
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，提供一种壁挂式空调室内机。
本发明一个进一步的目的是要使得在不影响到室内机的调温效果前提下调节送风气流的方向。
本发明另一个进一步的目的是要当第一导流板处于关闭位置时，第二导流板可以实现单导风板的作用，以实现将热风向下导出。
特别地，本发明提供了一种壁挂式空调室内机，包括：
机壳，其开设有朝下敞开的出风口；
第一导流板，可上下平移地设置于出风口处，配置成可运动至关闭出风口至少部分区域的关闭位置，或运动至出风口下方，以利用其上表面将从出风口排出的送风气流向前引导的导风位置；和
第二导流板，可动地设置于出风口处，配置成在第一导流板处于导风位置时，可运动至第一导流板与出风口的后边缘之间，以将从出风口排出的送风气流导向第一导流板。
进一步地，第二导流板可转动地安装于出风口处，并配置成可受控地转动，以对从第一导流板和出风口后边缘之间流出的送风气流的方向进行引导。
进一步地，第一导流板和第二导流板配置成：可运动至在出风口下方前 后排列以共同关闭出风口的位置。
进一步地，第一导流板和第二导流板配置成：可运动至使第一导流板位于第二导流板上方，并由第二导流板关闭出风口的位置。
进一步地，第一导流板和第二导流板还配置成：
当第一导流板处于导风位置时，使其与第二导流板搭接相连。
进一步地，壁挂式空调室内机还包括：
风道，设置于机壳内，用于将机壳内形成的送风气流引导至出风口处；且
风道的前壁临近出风口的区段为内凹型弯曲状；
风道的后壁临近出风口的区段为外凸形弯曲面。
进一步地，出风口前端与风道的前壁之间具有朝下的贴合面；
第一导流板在处于关闭位置时，贴靠于贴合面下侧。
进一步地，出风口的前端处于其后端的前上方；且
第一导流板在处于导风位置时，自后向前逐渐向上倾斜延伸。
进一步地，第一导流板与水平方向的夹角在10°～20°之间。
进一步地，壁挂式空调室内机还包括：
至少一套驱动机构，用于驱动第一导流板上下平移，每套驱动机构包括电机、相互啮合的齿轮和齿条，电机安装于机壳，齿轮安装于电机，齿条沿竖直方向延伸且形成于第一导流板。
本发明的壁挂式空调室内机中，由于出风口朝下敞开，第一导流板可上下平移地设置于出风口处，第二导流板可动地设置于出风口处，在第一导流板处于导风位置时，第二导流板可运动至第一导流板与出风口的后边缘之间，因此第二导流板可以起到将至少一部分送风气流引导至第一导流板的后端，最终使送风气流从第一导流板从后向前地被引导，进而使得送风气流更加聚合，送风调节更加高效，并且当第一导流板向平移至导风位置，第一导流板处于出风口的外部，不会对出风口的出风面积产生影响，进而不会影响到室内机的调温效果。
进一步地，本发明的壁挂式空调室内机中，第二导流板可转动地安装于出风口处，第一导流板和第二导流板可以运动至在出风口下方前后排列以共同关闭出风口的位置，也可以运动至使第一导流板位于第二导流板上方，并由第二导流板关闭出风口，当第一导流板处于关闭位置时，第二导流板可以 实现单导风板的作用，转动至向下延伸的位置，以实现将热风向下导出。

具体实施方式

请参见图1至图4，图1是根据本发明一个实施例的壁挂式空调室内机的示意图，图2是根据本发明第一个实施例的室内机中第一导流板处于导风位置的截面图，图3是根据本发明第一个实施例的室内机中第一导流板和第二导流板共同关闭出风口时的截面图，图4是根据本发明第一个实施例的室内机中第一导流板处于关闭位置的截面图，图中箭头示出了气流的方向。
本发明提出一种壁挂式空调室内机1，其一般性地可以包括机壳10、换热器20、换热风扇30等元器件。
机壳10作为室内机1的外壳，保护着整个室内机1，并且机壳10上还设置有至少一个进风口12和至少一个出风口13。在一些实施例中，出风口13可以开设于机壳10的下壁，使其朝下敞开。
机壳10的内部还可以限定出换热空间16，换热空间16用于安装换热器20和换热风扇30，在换热风扇30的促使下室内空气可以从进风口12进入换热空间16，并与换热器20进行换热，形成送风气流，最终送风气流可以从出风口13排入室内，以调节室内的温度。
请参见图2至图4，在一些实施例中，该壁挂式空调室内机11还可以包括第一导流板40和第二导流板50。
第一导流板40可上下平移地设置于出风口13处，并且第一导流板40还可以配置成可运动至关闭出风口13至少部分区域的关闭位置，或者运动至出风口13下方，以利用其上表面将从出风口13排出的送风气流向前引导的导风位置。
请参见图2和图3，在本实施例中，第一导流板40可以位于出风口13的至少部分区域的下方，并且在相对该部分区域作上下平移运动。当第一导流板40向上移动至出风口13处(即关闭位置)，以关闭出风口13。当第一 导流板40从关闭位置向下移动至导风位置时，第一导流板40打开出风口13该部分区域，机壳10内形成的送风气流可以从出风口13的该部分区域排出，并在第一导流板40的作用下向前引导。
第二导流板50可动地设置于出风口13处，第二导流板50可以在第一导流板40处于导风位置时，可运动至第一导流板40与出风口13的后边缘之间，以将从出风口13排出的送风气流导向第一导流板40。
请参见图2，在本实施例中，当第一导流板40处于导风位置时，第一导流板40与出风口13之间存在一定间隙，为了使机壳10内形成的送风气流能够受到第一导流板40的引导，第二导流板50可以在第一导流板40处于导风位置时运动至第一导流板40与出风口13的后边缘之间，这样第二导流板50可以起到将至少一部分送风气流引导至第一导流板40的后端，最终使送风气流从第一导流板40从后向前地被引导，进而使得送风气流更加聚合，送风调节更加高效。
例如，在室内机1处于制冷模式时，用户可以通过调节第一导流板40和第二导流板50，以使第一导流板40处于导风位置，第二导流板50处于第一导流板40与出风口13的后边缘之间，这样从机壳10内排出的冷风依次在第二导流板50和第一导流板40的导向下向前导出，使得冷风平吹，改善用户风感体验，提升送风舒适度。
如背景技术部分所述，现有技术中为了调节空调室内机的送风方向，一般是在出风口处设置可以上下摆动的导风板。但是上述这种调节方式具有一定的缺陷。虽然用户可以通过调节导风板的角度来改变气流方向，但是这种调节手段可能带来其他影响，例如导风板在向上摆动的过程中，导风板正对出风口的面积越来越大，导致在调节送风方向时降低了出风量，影响空调的调温效果。
为了克服现有技术中的缺陷，本实施例的壁挂式空调室内机1采用两块导流板(即第一导流板40和第二导流板50)相互配合实现调节送风气流的方向。
具体地，当第一导流板40向下平移至导风位置时，第二导流板50运动至第一导流板40与出风口13的后边缘之间，以将出从出风口13排出的送风气流导向第一导流板40，最终由第一导流板40利用其上表面将送风气流向前引导。
由于第一导流板40向平移至导风位置时，第一导流板40向下平移，因此，第一导流板40在离开关闭位置并向导风位置平移地过程中和处于导风位置时，第一导流板40处于出风口13的外部，这不会对出风口13的出风面积产生影响，进而不会影响到室内机1的调温效果。
请参见图2至图4，在一些实施例中，第二导流板50可转动地安装于出风口13处，并配置成可受控地转动，以对从第一导流板40和出风口13后边缘之间流出的送风气流的方向进行引导。
由于第一导流板40需要将从出风口13排出的送风气流向前引导，第二导流板50可运动至第一导流板40与出风口13的后边缘之间，以将从出风口13排出的送风气流导向第一导流板40，因此第一导流板40可以设置于出风口13靠前的位置，而第二导流板50可以设置于出风口13靠后的位置，以便于将从出风口13排出的送风气流导向第一导流板40。
在一些具体的实施例中，第二导流板50的一端可以直接地枢转连接于出风口13的后壁上，以实现第二导流板50绕出风口13转动。
请参见图2至图4，在另外一些实施例中，第二导流板50的枢转轴还可以设置于出风口13的后壁前方，当第二导流板50向外转动时，其枢转轴的后端部分向出风口13的内部转动，这样有利于将送风气流从机壳10的内部导出。
请参见图3，在一些实施例中，第一导流板40和第二导流板50还可以运动至在出风口13下方前后排列以共同关闭出风口13的位置。
在本实施例中，第一导流板40和第二导流板50的宽度之和可以配置成与出风口13的宽度相等。也即是，当第一导流板40处于关闭位置时，第二导流板50可以运动至使其一端与第一导流板40的端部相接，以实现第一导流板40和第二导流板50分别关闭其对应的出风口13，最终共同地封闭整个出风口13。
可选地，第一导流板40和第二导流板50的宽度之和还可以配置成大于出风口13的宽度，这样当第一导流板40处于关闭位置时，第一导流板40和第二导流板50相对的部分可以重叠，也可以实现上述技术效果。
需要注意的是，当第一导流板40和第二导流板50相对的部分重叠时，第二导流板50要处于第一导流板40下方，以避免第一导流板40阻挡第二导流板50运动。
请参见图5至图7，图5是根据本发明第二个实施例的室内机中第一导流板处于导风位置的示意图，图中箭头示出了气流的方向，图6是根据本发明第二个实施例的室内机中由第二导流板关闭出风口时的截面图，图7是根据本发明第二个实施例的室内机中第一导流板处于关闭位置的截面图，图中箭头示出了气流的方向。
请参见图6，在另外一些实施例中，第一导流板40和第二导流板50还可以运动至使第一导流板40位于第二导流板50上方，并由第二导流板50关闭出风口13的位置。
也即，在该实施例中，第二导流板50宽度可以配置成至少与出风口13的宽度相等。第二导流板50可以转动地开闭出风口13，并且在第二导流板50关闭出风口13的位置时同时将第一导流板40包裹在出风口13内，以使得室内机1外观更加整齐美观。
另外，在本实施例中，第二导流板50不仅要起到关闭出风口13的作用，而且要实现将从出风口13排出的送风气流导向第一导流板40，因此，第一导流板40位于第二导流板50上方也能够避免第一导流板40阻挡第二导流板50运动。
请参见图5，在制冷模式下，用户需要将冷风向前引导时，第二导流板50可以先转动至预设位置处，从而避让出第一导流板40的平移路径，然后第一导流板40可以从关闭位置向导风位置移动，最终使得第二导流板50处于第一导流板40和出风口13后边缘之间。
请参见图7，在制热模式下，用户需要将热风向下引导时，这时由于第一导流板40仅关闭部分出风口13，且第二导流板50处于第一导流板40的下方，其转动不受第一导流板40的影响，这时第二导流板50可以实现单导风板的作用，转动至向下延伸的位置，以实现将热风向下导出。
需要说明的是，上述举例仅是为了更加清楚地描述本实施例的第一导流板40和第二导流板50的工作原理，并非用于限定第一导流板40和第二导流板50处于何种位置时室内机1处于何种调温模式(制热或者制冷)。用户可以根据实际情况任意调节第一导流板40和第二导流板50的工作位置，例如，在制热模式下将第一导流板40调节至导风位置等，在此不作赘述。
请参见图5，进一步地，在由第二导流板50关闭出风口13的情况下，当第一导流板40处于导风位置时，第一导流板40可以与第二导流板50搭 接相连。
由于当由第二导流板50关闭出风口13时，第二导流板50的宽度至少与出风口13的宽度相等，而第一导流板40被第二导流板50包裹在其上方，这样当第一导流板40从关闭位置向导风位置移动时其后端必然能够搭接在第二导流板50上。这样，在第一导流板40处于导风位置时，第一导流板40和第二导流板50之间不存在间隙，经过第二导流板50导向的送风气流能够全部被导向第一导流板40，避免了一部分送风气流从第一导流板40和第二导流板50之间漏出，进一步使得送风更加聚合。
请参见图2至图4，在一些实施例中，该壁挂式空调室内机1还可以包括风道60。风道60设置于机壳10内，用于将机壳10内形成的送风气流引导至出风口13处，并且风道60的前壁62临近出风口13的区段为内凹型弯曲状，风道60的后壁64临近出风口13的区段为外凸形弯曲面。
众所周知，热空气的密度相对冷空气较小，因此在制冷模式下风道60内的送风气流偏下，而在制热模式下风道60内的送风气流偏上。
在本实施例中，风道60的还可以设置成从后向前向下延伸，这样风道60的前壁62临近出风口13的区段设置成为内凹型弯曲状能够起到下压热风的作用；同理，风道60的后壁64临近出风口13的区段设置成外凸形弯曲面能够起到上扬冷风的作用。总之，本实施例中的风道60形状更有利于向下或向上导出送风气流，减少热风或冷风流动损失，提高室内机1的效率。
请参见图5至图7，进一步地，出风口13前端与风道60的前壁62之间具有朝下的贴合面66，第一导流板40在处于关闭位置时，贴靠于贴合面66下侧。
在制热模式下，第一导流板40在处于关闭位置，仅利用第二导流板50即可进行热风向下导向，第一导流板40贴靠于贴合面66下侧，尽量减小对出风口13的遮挡，提高了出风量。
请参见图8至图10，图8是根据本发明第三个实施例的室内机中第一导流板处于导风位置的示意图，图中箭头示出了气流的方向，图9是根据本发明第三个实施例的室内机中第一导流板和第二导流板共同关闭出风口时的截面图，图10是根据本发明第三个实施例的室内机中第一导流板处于关闭位置的截面图，图中箭头示出了气流的方向。
请参见图8，在一些实施例中，出风口13的前端处于其后端的前上方， 并且第一导流板40在处于导风位置时，自后向前逐渐向上倾斜延伸。
在本实施例，第一导流板40在送气气流的流动方向上处于斜向上延伸的状态，这样当第一导流板40处于导风位置时更加有利于将冷风向上引导。
请参见图9，由于第一导流板40处于向上倾斜延伸，并且出风口13的前端处于其后端的前上方，这样当第一导流板40处于关闭位置时，第一导流板40可以实现与出风口13的前端平齐，以使得在关闭位置时室内机1的保持一定的整齐性，外观更加美观。
请参见图10，在制热模式下，用户需要将热风向下引导时，第二导流板50可以实现单导风板的作用，转动至向下延伸的位置，以实现将热风向下导出。
请参见图11，图11是根据本发明第三个实施例的室内机中第一导流板在关闭位置和导风位置切换的状态示意图，其中虚线表示处于第一导流板处于导风位置时的第一导流板和第二导流板，虚线圆表示第二导流板端部的运动轨迹。
另外，由于第一导流板40向上倾斜延伸，第一导流板40处于关闭位置时第二导流板50同样朝向上倾斜延伸。在第一导流板40和第二导流板50共同关闭出风口13的情况下，在某一特定的位置处(如图11所示)，第一导流板40和第二导流板50可以实现搭接相连。相对于由第二导流板50关闭出风口13的实施例，本实施的第二导流板50的宽度可以大大缩短，节约了成本。
在一些优选的实施例中，第一导流板40与水平方向的夹角可以设置成处于10°～20°之间，例如10°、15°或者20°等。
传统的室内机的出风口与水平方向的夹角一般呈30°～45°之间，而本实施例中由于出风口13的前端处于其后端的前上方，第一导流板40自后向前逐渐向上倾斜，第一导流板40在关闭位置时可以实现与方向出风口13保持一致，通过上述角度限定不仅能够利用第一导流板40实现向前向上送风，又能够实现隐藏出风口13，使得室内机1的机壳10造型更加美观。
需要说明的是，上述实施例是以出风口13的前端处于其后端的前上方，且第一导流板40自后向前逐渐向上倾斜延伸，且第一导流板40和第二导流板50共同关闭出风口13为例进行说明，本领域技术人员在知晓上述实施例的情况下还可以作适当的变形，例如将出风口13的关闭方式替换成由第二 导流板50单独地关闭，在此不作赘述。
请参见图2、图5和图8，在一些实施例中，该壁挂式空调室内机1还可以包括一套驱动机构，用于驱动第一导流板40上下平移，每套驱动机构包括电机72、相互啮合的齿轮74和齿条76，电机72安装于机壳10，齿轮74安装于电机72，齿条76沿竖直方向延伸且形成于第一导流板40。可选地，电机72可以配置成步进电机，尤其是直流步进电机。
在一些实施例中，为了使驱动机构的驱动效果更加平稳，驱动机构的数量可以设置成多套，例如两套等，两套驱动机构分别设置于第一导流板40的横向两侧，两个驱动机构的电机72可以同时启停，以平稳地驱动第一导流板40上下平移。
本发明的壁挂式空调室内机1中，由于出风口13朝下敞开，第一导流板40可上下平移地设置于出风口13处，第二导流板50可动地设置于出风口13处，在第一导流板40处于导风位置时，第二导流板50可运动至第一导流板40与出风口13的后边缘之间，因此第二导流板50可以起到将至少一部分送风气流引导至第一导流板40的后端，最终使送风气流从第一导流板40从后向前地被引导，进而使得送风气流更加聚合，送风调节更加高效，并且当第一导流板40向平移至导风位置，第一导流板40处于出风口13的外部，不会对出风口13的出风面积产生影响，进而不会影响到室内机1的调温效果。
本发明的壁挂式空调室内机1中，第二导流板50可转动地安装于出风口13处，第一导流板40和第二导流板50可以运动至在出风口13下方前后排列以共同关闭出风口13的位置，也可以运动至使第一导流板40位于第二导流板50上方，并由第二导流板50关闭出风口13，当第一导流板40处于关闭位置时，第二导流板50可以实现单导风板的作用，转动至向下延伸的位置，以实现将热风向下导出。
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。
