Description

空调器 技术领域
本发明涉及空气调节领域，特别是涉及一种空调器。
背景技术
现有空调器中存在在机壳顶部开设进风口来进风的方案，虽减少了占用空间，但灰尘会从顶部的进风口落入到机壳内部，并随时间积聚在换热器和风机叶轮上，容易滋生细菌，影响用户健康。为减少落入到机壳内部的灰尘，现有技术在上进风口处设置过滤网来阻挡灰尘，但过滤网不易拆卸清洁。综合考虑，在设计上需要一种可减少自上进风口落入到机壳内部的灰尘并便于清洁的空调器。
发明内容
本发明的一个目的是要克服现有技术的至少一个技术缺陷，提供一种空调器。
本发明一个进一步的目的是要减少落入到机壳内部的灰尘。
本发明另一个进一步的目的是要提高空调器的进风量。
特别地，本发明提供了一种空调器，其特征在于，包括：
机壳，顶部开设有上进风口；
送风风机，设置于所述机壳内，并配置为自所述上进风口吸入空气；以及
上进风栅，设置于所述上进风口处，其包括形成有多个上开口的主体和相对于所述主体向上拱起的多个遮挡部；其中
每个所述遮挡部设置为在水平面上的投影覆盖一个所述上开口的至少一部分；
多个所述遮挡部设置为使其在竖直平面内的投影高度沿空气向对应的上开口流动的方向逐渐升高。
可选地，所述多个遮挡部设置为使空气向多个所述上开口流动的方向均相同。
可选地，每个所述遮挡部包括：

可选地，每个所述遮挡部设置为自一个所述上开口的宽度方向上的一个侧向边缘向上并向靠近该上开口的宽度方向上的另一个侧向边缘的方向平滑延伸。
可选地，所述多个遮挡部均设置为自后向前延伸。
可选地，相邻两个所述上开口的间距大于所述遮挡部的厚度。
可选地，所述遮挡部设置为在水平面上的投影完全覆盖一个所述上开口；且
相邻两个所述上开口的间距为所述上开口在宽度方向上的尺寸的3/5～1；和/或
所述遮挡部的延伸末端与所述上开口的最小间距为所述上开口在宽度方向上的尺寸的1/5～1/2；和/或
所述遮挡部与其相邻遮挡部在竖直平面内的投影的高度差为所述上开口在宽度方向上的尺寸的1/5～2/5。
可选地，所述机壳的底部还开设有下进风口；
所述送风风机为双吸式离心风机，所述离心风机的转动轴线竖直设置；且所述空调器还包括：
两个换热器，分别设置于所述上进风口和所述下进风口与所述离心风机的进风路径上。
可选地，所述空调器还包括：
下进风栅，包括在竖直方向上间隔设置的多个格栅板，每个所述格栅板均包括间隔设置的多个栅条，每相邻两个所述栅条之间形成有下开口，以供空气流过；且
每个所述格栅板的下开口在水平面上的投影均落入其他所述格栅板的多个栅条在水平面上的投影中。
本发明的空调器通过在机壳的上进风口处设置上进风栅，并为上进风栅的每个上开口设置至少部分遮挡该上开口的遮挡部，可在不增加占用空间的同时，减少自上进风口落入机壳内部的灰尘，进而缩短了空调器的清洁周期， 提高了用户便利性。
进一步地，本发明通过将多个遮挡部设置为在竖直平面内的投影高度沿空气向对应开口流动的方向逐渐升高，使得流经多个上开口的空气流量均匀，提高了空调器的进风量，延长了送风风机的使用寿命，避免了换热器换热不均匀、造成冷量或热量的浪费，保证了空调器的制冷制热性能。
进一步地，本发明的遮挡部设置为自上开口的宽度方向上的一个侧向边缘向上并向靠近该上开口的宽度方向上的另一个侧向边缘弯折延伸，可在保证进风风量的同时，防止灰尘随气流运动至机壳的内部，进一步地减少了自顶部进风口落入机壳内部的灰尘。
进一步地，本发明的进风栅设置为从其前侧吸入室内空气，相比于进风栅从其他方向吸入室内空气，保证了空调器的进风量，避免了空调器的性能下降。
进一步地，本发明的下进风栅包括在竖直方向上间隔设置的多个格栅板，每个格栅板的下开口在水平面上的投影可均落入其他格栅板的多个栅条在水平面上的投影中，使换热器产生的冷凝水可在自身重力作用下落在栅条上，而不会通过格栅板任意一个下开口滴落在机壳的外部，在不影响下进风口的进风量的同时使下进风栅复合了接水盘的功能，且结构简单，不会增加额外的生产成本。

换热器131和换热器132可分别设置于上进风口111和下进风口112与送风风机120的进风路径上，以与流经的空气进行热交换。
上进风口111处可设置有上进风栅140。特别地，上进风栅140可包括形成有供空气流过的多个上开口142的主体141和相对于主体141向上拱起的多个遮挡部143。每个遮挡部143可设置为在水平面上的投影覆盖一个上开口142的至少一部分。
本发明的空调器100通过在机壳110的顶部进风口处设置上进风栅140，并为上进风栅140的每个上开口142设置至少部分遮挡该上开口142的遮挡部143，可在不增加占用空间的同时，减少自顶部进风口落入机壳110内部的灰尘，进而缩短了空调器100的清洁周期，提高了用户便利性。
图3是图2中区域A的示意性放大视图，其示出了本发明一个实施例的上进风栅140结构。参见图3，在一些实施例中，每个遮挡部143可包括自一个上开口142的宽度方向上的一个侧向边缘向上延伸的连接段143a和自 连接段143a的上侧端部向靠近该上开口142的宽度方向上的另一个侧向边缘的方向延伸的遮挡段143b。即，遮挡部143可设置为自上开口142的宽度方向上的一个侧向边缘向上并向靠近该上开口142的宽度方向上的另一个侧向边缘弯折延伸，可在保证进风风量的同时，防止灰尘随气流运动至机壳110的内部，进一步地减少了自顶部进风口落入机壳110内部的灰尘。图2所示出的前后延伸方向平行于上开口142的宽度方向。
在一些进一步地实施例中，相邻两个上开口142的间距W 1可大于遮挡部143的厚度，以进一步地减少自顶部进风口落入机壳110内部的灰尘。
在一些进一步地实施例中，遮挡段143b可设置为水平延伸，以进一步地减少自顶部进风口落入机壳110内部的灰尘。其中，“水平”方向是相对于空调器100的实际使用状态而言的。
在一些进一步地实施例中，多个遮挡部143可设置为使其在竖直平面内的投影高度沿空气向对应上开口142流动的方向逐渐升高，以使得流经多个上开口142的空气流量均匀，提高了空调器的进风量，延长了送风风机的使用寿命，避免了换热器换热不均匀、造成冷量或热量的浪费，保证了空调器的制冷制热性能。
在一些进一步地实施例中，多个遮挡部143相对于主体141的延伸趋势可相同。即，多个遮挡部可设置为使空气向多个上开口142的流动方向均相同，以避免气流紊流、进风量减少的情况发生。在本发明中，空气的流动方向相同是指空气的流动趋势，不包括具体的角度。例如，空气的流动方向为由前向后并向下倾斜。
在另一些进一步地实施例中，多个遮挡部143可被划分为空气向其对应上开口142流动的方向不同的多个遮挡组，每个遮挡组包括至少一个遮挡部143。具有多个遮挡部143的遮挡组设置为其多个遮挡部143可设置为在竖直平面内的投影高度沿空气向对应上开口142流动的方向逐渐升高。
在一些进一步地实施例中，遮挡部143可设置为在水平面上的投影完全覆盖一个上开口142。相邻两个上开口142的间距W 1可为上开口142在宽度方向上的尺寸W 2的3/5～1，例如3/5、4/5或1。遮挡部143的延伸末端与上开口142的最小间距H 1可为上开口142在宽度方向上的尺寸W 2的1/5～1/2，例如1/5、1/4、或1/2。遮挡部143与其相邻遮挡部143在竖直平面内的投影的高度差H 2可为上开口142在宽度方向上的尺寸W 2的1/5～2/5， 例如1/5、1/4、或2/5，以提高进风量并保证进风量的均匀性。
在一些进一步地实施例中，多个遮挡部143可均设置为自后向前延伸，以保证空调器100的进风量，避免空调器100的性能下降。图2中箭头方向示出前后延伸方向。
在一些进一步地实施例中，上进风栅140还可包括多个端板144。每两个端板144可分别设置于一个遮挡部143的纵向两侧，并与该遮挡部143和主体141连接。即，每个遮挡部143的两端可分别设置有一个端板144来与主体141连接，以提高上进风栅140的结构强度。
在另一些实施例中，每个遮挡部143可设置为自一个上开口142的宽度方向上的一个侧向边缘向上并向靠近该上开口142的宽度方向上的另一个侧向边缘的方向平滑延伸，以降低风阻，提高气流流动的顺畅性。平滑延伸指遮挡部143的延伸路径的曲线方程为一阶导数连续的曲线。在工程中意味着遮挡部143的无尖角。
图4是图2中区域A的示意性放大视图，其示出了本发明另一个实施例的上进风栅结构。参见图4，其与图3实施例的区别为连接段143a和遮挡段143b采用圆弧过渡连接。
图5是图2中区域A的示意性放大视图，其示出了本发明又一个实施例的上进风栅结构。参见图5，其与图3实施例的区别为遮挡部143为线性延伸。
图6是本发明一个实施例的下进风栅150的示意性剖视图。参见图6，下进风口112处可设置有下进风栅150。下进风栅150可包括在竖直方向上间隔设置的多个格栅板151。每个格栅板151均包括间隔设置的多个栅条152，每相邻两个栅条152之间形成有下开口153，以供空气流过。
每个格栅板151的下开口153在水平面上的投影可均落入其他格栅板151的多个栅条152在水平面上的投影中，即换热器132产生的冷凝水可在自身重力作用下落在栅条152上，而不会通过任意一个下开口153滴落在机壳的外部，在不影响下进风口112的进风量的同时使下进风栅150复合了接水盘的功能，且结构简单，不会增加额外的生产成本。
每个格栅板151的每个栅条152均具有向上开口的凹槽，用于收集换热器132产生的冷凝水。凹槽可沿栅条152的长度方向延伸。
凹槽的底壁可设置为自其中部向其两端向下倾斜延伸，以避免冷凝水积 聚在凹槽内。
除最下层的格栅板151之外的其他任一层格栅板151均直接或间接地与最下层的格栅板151连通，以将冷凝水汇集到最下层的格栅板151，便于冷凝水的排出。
每个格栅板151还设置有外框154，且每个外框154形成有汇流槽。每个栅条152的凹槽的纵向两端均与一个汇流槽连通，以便于收集冷凝水。多个格栅板151的汇流槽可通过管道逐层连通。
每个格栅板151可设置为自前向后倾斜向下延伸。多个格栅板151的汇流槽的后部可被连通，以便于冷凝水的排出。
多个格栅板151可大致平行设置，以缩小下进风栅150在竖直方向上的占用面积，提高整机结构紧凑性。
相邻两个格栅板151的间距可大于任意一个下开口153在宽度上的尺寸的二倍，以确保相邻两个格栅板151之间具有充足的空间供气流改变方向，减小风阻，进而保证了下进风口112的进风量。
多个格栅板151的下开口153宽度可自下至上逐渐增大，以避免冷凝水外漏，并在整体上减小风阻，提高换热效率。
在本发明中，空调器100可为采用蒸汽压缩制冷系统的空调室内机(或空调室外机)、空气净化器、空气加湿器等。
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。
