Description

壁挂式空调室内机 技术领域
本发明涉及空气调节技术领域，特别涉及一种壁挂式空调室内机。
背景技术
随着空调的普及，用户对送风的舒适性和健康的要求越来越高。现有的空调送风强劲，制冷时送风温度较低，制热时送风温度过高，都会引起用户的不舒适，用户的风感体验较差。
发明内容
本发明的目的是要提供一种壁挂式空调室内机，以提升送风的舒适度，改善用户的风感体验。
本发明的进一步的目的是要能够根据需求调节混风风道的过流面积和流向，以使混风更加均匀充分，进一步提升混风效果。
特别地，本发明提供了一种壁挂式空调室内机，包括：
壳体，其顶部具有进风口，底部前侧具有朝向前下方并沿横向方向延伸的出风口；
蒸发器，设置在壳体内，用于与从进风口流入的空气进行热交换，形成热交换风；
风机，配置成促使空气从蒸发器处流向出风口；
引流件，长度方向沿横向延伸地设置在壳体的底部下方，与壳体底部限定出混风风道，以允许壳体下方的室内空气经混风风道流向出风口，与热交换风混合形成混流风再吹向室内；和
引流导风板，可沿一横向轴线转动地安装在引流件上，并位于混风风道内，以便受控地转动来调节混风风道的过流面积以及气流方向。
可选地，壁挂式空调室内机还包括：连接件，其一端连接于引流件的长度方向的中部，另一端连接于壳体的底部的横向中部。
可选地，连接件上安装有电机以及受电机驱动的左转轴和右转轴；且引流导风板包括左右排列的左导风板和右导风板，左导风板的右端固定安装于左转轴，右导风板的左端固定安装于右转轴。
可选地，连接件与引流件、连接件与壳体之间均为可拆卸连接。
可选地，引流件的横截面呈椭圆形，且该椭圆形横截面的长轴从前向后倾斜向上延伸。
可选地，风机的数量为两个且均为贯流风机，两个贯流风机的中心旋转轴线沿横向方向延伸且共线设置；且出风口的数量为两个，每个出风口的位置与一个贯流风机相对应。
可选地，壳体底部表面包括：从壳体底部后端向前水平延伸的水平段；从水平段的前端向前上方延伸至出风口的下边缘的倾斜段；和从倾斜段的前端向前下方延伸的折流段。
可选地，倾斜段的表面形成有多条均沿横向方向延伸且相互平行的凸筋。
可选地，蒸发器为覆盖贯流风机前方和上方空间的三段式蒸发器。
可选地，引流件的横向两端与壳体的横向两端平齐；且引流导风板的横向两端与出风口的横向两端平齐。
本发明的壁挂式空调室内机中，引流件与壳体底部限定出了混风风道。热交换风从出风口吹出时，出风口的下侧边缘形成负压，能够吸入混风风道内的空气，使得壳体下方的室内空气经混风风道源源不断流向出风口，与热交换风混合，形成混流风再吹向室内。在制冷模式下，混流风的温度高于热交换风，在制热模式下，混流风的温度低于热交换风。本发明能够避免温度过低或过高的热交换风吹向人体，引起人体不适。总之，空调室内机将混流风吹向室内，将使风更加柔和，提升了送风的舒适度，改善用户的风感体验。同时，因为额外的室内空气混入热交换风，使出风口的总风量增加，加快了制冷/制热速度。
此外，本发明还能够通过转动引流导风板来改变混风风道的过流面积和气流方向，也就是改变混风风道的风量和风向。如此便于空调室内机通过改变混风风道的风量来调节室内空气和热交换风的混合比例，通过改变混风风道的风向来调节室内空气汇入热交换风的方向，以利于两者混合，使两者混合地更加均匀。
进一步地，本发明的壁挂式空调室内机仅仅使引流件的横向中部通过连接件安装于壳体，其余部分均不和壳体接触，不仅使结构更加简单，也更加利于引流件横向两端的混流过程。
进一步地，本发明的壁挂式空调室内机中，壳体底部表面底部包括水平段、倾斜段以及折流段。室内空气沿着壳体底部表面流动，经折流段后转向，以与热交换风的流向趋于一致，减少两者合流时产生的噪声。倾斜段上的多条凸筋能够在制冷时增加与冷风的接触面积，并且能够使其上形成的冷凝水因凸筋的阻隔不会凝聚滴落。

具体实施方式
下面参照图1至图5来描述本发明实施例的壁挂式空调室内机。在下文描述中，“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，仅是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示意性正视图，图2是图1所示壁挂式空调室内机的侧面剖视图，图2中用箭头示意了风向。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100、蒸发器200、风机300、引流件600以及引流导风板620、630。该壁挂式空调室内机与空调室外机(未图示)一同构成蒸气压缩制冷循环系统，实现对室内环境的制冷/制热。壳体100的顶部具有进风口101，底部前侧具有朝向前下方并沿横向方向延伸的出风口102。进风口101用于允许室内环境 的空气进入壳体100内部，出风口102用于向室内环境送风。壳体100可为横向(即左右方向)延伸的长条状结构。出风口102可为沿着横向方向延伸的长条形开口。出风口102开设在壳体100的底部并朝向前下方是为了方便壁挂式空调室内机安装在墙上时向下送风。
蒸发器200设置在壳体100内，用于与从进风口101进入壳体100的空气进行热交换，形成热交换风(具体地，制冷时为冷风，制热时为热风)。
壳体100内设置有主风道110，主风道110的前边缘构成出风口102。主风道110用于将热交换风从蒸发器200处引流至出风口102处，向室内吹风实现制冷/制热。
风机300设置在主风道110内，配置成促使空气从蒸发器200处流至出风口102处，即为风从出风口102吹向室内提供动力。风机300优选为中心旋转轴线沿横向方向延伸的贯流风机。蒸发器200优选为覆盖贯流风机300前方和上方空间的三段式蒸发器，进一步地，可为翅片式蒸发器。
风机300的数量可为一个，也可为多个。例如，风机300的数量可为两个且均为贯流风机，两个贯流风机300的中心旋转轴线沿横向方向延伸且共线设置。与之相对应地，出风口102的数量也为两个，每个出风口102的位置与一个贯流风机300相对应。设置两个贯流风机300能够丰富送风模式。例如当风量需求小时，可仅开启一个贯流风机。风量需求大时，可同时开启两个贯流风机300。并且，两个贯流风机同时开启时，其风向也可设置为不同，以便同时向两个区域送风。
引流件600为长条状结构，其长度方向沿横向延伸地设置在壳体100的底部下方，以与壳体100底部限定出混风风道601，以允许壳体100下方的室内空气经混风风道601流向出风口102，与热交换风混合形成混流风再吹向室内，图2的箭头大致示意了风向。
引流导风板620、630可沿一横向轴线转动地安装在引流件600上，并位于混风风道601内，以便受控地转动来引导混风风道601的过流面积以及气流方向。
本发明实施例中，混风风道601的出口位于出风口102的下方。热交换风从出风口102吹出时，出风口102的下侧边缘形成负压，能够吸入混风风道601内的空气，使得壳体100下方的室内空气经混风风道601源源不断流向出风口102，与热交换风混合，形成混流风再吹向室内。在制冷模式下， 混流风的温度高于热交换风，在制热模式下，混流风的温度低于热交换风。本发明能够避免温度过低或过高的热交换风吹向人体，引起人体不适。总之，空调室内机将混流风吹向室内，将使风更加柔和，提升了送风的舒适度，改善用户的风感体验。同时，因为额外的室内空气混入热交换风，使出风口102的总风量增加，加快了制冷/制热速度。
此外，本发明实施例中，可通过转动引流导风板620、630来改变混风风道601的过流面积和气流方向，也就是改变混风风道601的风量和风向。如此便于空调室内机通过改变混风风道601的风量来调节室内空气和热交换风的混合比例，通过改变混风风道601的风向来调节室内空气汇入热交换风的方向，以利于两者混合，使两者混合地更加均匀。以制冷模式为例，空调室内机的热交换风温度越低，使混风风道601的过流面积越大，以加大混风量，使热交换风温度升高幅度更大。热交换风的风速越大(热交换风的风量也增大)，使混风风道601的过流面积越大，加大混风量。
图3是图1中引流件600、引流导风板620、630和连接件610的装配示意图，图4是图3所示结构的分解示意图，图5是图4的A部放大图。
如图3至图5所示，在一些实施例中，壁挂式空调室内机还包括连接件610，其一端连接于引流件600的长度方向的中部，另一端连接于壳体100的底部的横向中部。
优选地，连接件610与引流件600、连接件610与壳体100之间均为可拆卸连接。具体如图5所示，连接件610的下端设置有U形的夹持部611，其夹在引流件600的凹陷部602上。夹持部611上设置有两个定位部614以及两个螺钉孔613，凹陷部602上开设有两个螺纹通孔603。两个定位部614上的上具有两个锥形凸起，以插入并定位于两个螺纹通孔603的下端，两个螺钉孔613与开两个螺纹通孔603相对，通过螺钉拧紧，将连接件610可拆卸地连接于引流件600。连接件610的上方具有卡扣616以及安装板618，安装板618上具有螺钉孔。卡扣616卡在壳体100横向中部的卡槽内，安装板618与壳体100之间采用螺钉连接，如此实现连接件610与壳体100的可拆卸连接。
本发明的壁挂式空调室内机仅仅使引流件600的横向中部通过连接件610安装于壳体100，其他部分均不和壳体100接触，不仅使结构更加简单，也更加利于引流件600横向两端的混流过程。例如图1所示，优选使引流件 600的横向两端与壳体100的横向两端平齐，使引流导风板620、630的横向两端与出风口102的横向两端平齐(左导风板620的左端与出风口102的左端平齐，右导风板630的右端与出风口102的右端平齐)，不仅使出风口102横向全区域实现混流效果，也是空调室内机的外观更加美观。
在一些实施例中，如图3至图5所示，连接件610上安装有电机(位于连接件610的后侧未显示)以及受电机驱动的左转轴615和右转轴619，并且，引流导风板包括左右排列的左导风板620和右导风板630，左导风板620的右端固定安装于左转轴615，右导风板630的左端固定安装于右转轴619。左导风板620的右端设置有安装板621，安装板621上开设有方孔，用于安装在方形的左转轴615上。右导风板630的左端设置有安装板631，安装板631上开设有方孔，用于安装在方形的右转轴619上。
在一些实施例中，如图2所示，引流件600的横截面呈椭圆形，且该椭圆形横截面的长轴从前向后倾斜向上延伸。如此，能够使壳体100后下方的空气先沿着椭圆形的窄边斜向上流动，再沿着宽边斜向下流动，以和热交换风更平稳地汇合。也使得空调室内机的外挂更加美观。在一些实施例中，如图2所示，壳体100底部表面包括从壳体100底部后端向前水平延伸的水平段130、从水平段130的前端向前上方延伸至出风口102的下边缘的倾斜段140和从倾斜段140的前端向前下方延伸的折流段150。倾斜段140的表面形成有多条均沿横向方向延伸且相互平行的凸筋142。如此，室内空气沿着壳体100底部表面流动，经折流段150后转向，以与热交换风的流向趋于一致，减少两者合流时产生的噪声。倾斜段140上的多条凸筋142能够在制冷时增加与冷风的接触面积，并且能够使其上形成的冷凝水因凸筋142的阻隔不会凝聚滴落。
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。
