  • the multiple oscillating blades 30 are integrated with the air guide plate 10, allowing the air guide structure 100 to simultaneously adjust the airflow in front of the air guide plate 10 in both the pitch and left-right directions. As the air guide plate 10 swings up and down, the multiple oscillating blades 30 also swing up and down, and can also swing left and right relative to the air guide plate 10, expanding the effective range of the oscillating blades 30.
  • the oscillating blades 30 achieve a good sweeping effect. Furthermore, compared to the related art, the multiple oscillating blades 30 in the present embodiment are closer to the air outlet 200b.

本申请实施例的多个摆风叶片与导风板连接,取消了多个摆风叶片与导风板之间的空间间隔,使结构更加紧凑,从而能够提高空间利用率,减少多个摆风叶片与导风板所占用的空间,有利于空调室内机进行超薄设计。而由于多个导风叶片与导风板转动连接,且导风板和多个摆风叶片分别通过第一驱动件和第二驱动件进行驱动,在导风板进行摆动时,多个摆风叶片也可相对于导风板摆动而改变导风板前侧的气流的流动方向,在减少占用空间的前提下,保证了导风板和摆风叶片的工作性能。
而且,本申请实施例中,由于多个摆风叶片与导风板相结合,使得导风结构能够同时对导风板前侧的气流进行俯仰方向和左右方向的调整。导风板进行上下摆动时,多个摆风叶片随之进行上下摆动,并可相对于导风板进行左右摆动,能够扩大摆风叶片的作用范围,在导风板悬停的任意角度,摆风叶片都能取得较好的扫风效果。且相较于相关技术,本申请实施例的多个摆风叶片更靠近出风口,通过多个摆动叶片调整后的气流直接从出风口流出,能够进一步提高扫风效果,提高用户体验。
此外,本申请实施例中,第一驱动件和第二驱动件均设置在安装座上,因而可集成连接线,便于导线连接。本申请实施例的导风结构可生产为单独的空调室内机的构件,即在进行空调室内机的组装时,导风结构能够作为独立的部件直接与壳体进行连接,提高空调室内机的模块化程度,便于调整装配工序,提升安装效率。

本申请实施例提出一种暖通系统,该暖通系统包括室外机和空调室内机1000,室外机和空调室内机1000通过管路连接,用于热交换的工作介质通过管路在室外机和空调室内机1000循环。
请参照图1和图2,室外机包括压缩机和室外换热器,压缩机和室外换热器均通过管路与空调室内机1000连接。空调室内机1000可安装在室内天花板或墙壁等位置,用于调节室内气温环境,其可以采用风管机或天花机等形式,本申请实施例对此不作限制。在一些实施例中,空调室内机1000包括机壳200、风机300、室内换热器400以及导风结构100。机壳200设有风道200a,并设有位于风道200a两端且与风道200a连通的回风口200c和出风口200b,室内换热器400和风机300均设于风道200a内,导风结构100设置在出风口200b处。
为便于描述,于本申请中,定义上下方向ZZ、前后方向YY以及左右方向XX,上下方向ZZ、前后方向YY以及左右方向XX两两呈夹角设置。
机壳200连接于室内天花板或墙壁,用于为空调室内机1000内的其他结构部件提供安装基础。机壳200可以视实际需要而采用多种形状,比如,机壳200可大致呈长方体状,以便于安装。机壳200构造形成上述风道200a,以供气体流动,风道200a沿前后方向YY延伸设置,回风口200c设置在机壳200的靠后的部分,出风口200b设置在机壳200的靠前的部分,从而使得气体能够通过回风口200c进入风道200a,并自后向前地运动而经过风机300和室内换热器400,而后通过出风口200b流出。
请参照图1,在一些实施例中,为便于装配,机壳200包括壳体201和面板202,风机300和室内换热器400均安装在壳体201内,壳体201与面板202连接以围合形成上述风道200a。其中,壳体201设有位于风机300一侧的出风通道201a,面板202设有上述出风口200b,出风口200b与出风通道201a连通,回风口200c可设置在面板202或壳体201上。示例性地,空调室内机1000安装在天花板,天花板设有安装口,壳体201设置在天花板上方,面板202设于壳体201的下方,并与壳体201连接。至少部分面板202于安装口处显露,在该显露出的部分,出风口200b和回风口200c沿前后方向YY在面板202上间隔设置,以保证回风和出风的顺畅性。如此,本申请实施例的机壳200不仅便于空调室内机1000的装配,在进行检修时,直接拆卸面板202即可将风机300和室内换热器400等构件显露,无需将空调室内机1000整个地拆卸,从而也提高了检修效率。
本申请实施例中,壳体201和面板202分别可以是铝合金或不锈钢等金属材质,以满足高强度和耐腐蚀等要求;或者,壳体201和面板202也可以采用塑料材质以实现风道200a组件的轻量化,本申请对此不作限制。例如,可以采用壳体201为金属材质,而面板202为塑料材质的搭配组合。此外,本申请实施例对壳体201和面板202的连接方式不作限定,它们可以单独或组合地通过卡接、铆接、焊接及螺栓连接等方式进行连接。
风机300设置在风道200a内,且能够抽取回风口200c处的气体,并对其做功以为上述风道200a内的气体循环提供动力。风机300可以是贯流风机、离心风机或者轴流风机等等。如图1所示,在一实施例中,风机300可选为贯流风机,贯流风机具有节能、风量大、噪音低、安装简单的优点。在这一实施例中,风机300包括叶轮和电机,叶轮呈沿左右方向XX延伸的长筒状设置,电机设置在叶轮的一端并与机壳200相连接,且电机的输出轴连接叶轮。叶轮周向上的一侧大致朝向回风口200c设置,定义叶轮的这一侧为进风侧;叶轮周向上的与进风侧间隔设置的另一侧大致朝向出风口200b设置,定义叶轮的这一侧为出风侧。沿叶轮的周向分布有多个叶片,电机驱动叶轮转动时,转动的叶片能够促使气体从进风侧向出风侧流动。
室内换热器400可设置在风机300靠近出风口200b的一侧或风机300靠近回风口200c的一侧,用于与流经风道200a并穿过室内换热器400的气体进行热交换,起到对气体进行制冷或制热的作用。比如,室内换热器400内穿设有多条冷媒管,多条冷媒管与室外机连接,冷媒在室内换热器400内流动。气体在穿过室内换热器400时与冷媒管内的冷媒换热,从而温度降低,形成低温空气。可选地,为提高换热效率,室内换热器400可以呈形、弧形或者波浪形设置,并可由一个单独的换热片构成,或由多个换热片组合而成。在如图1所示的实施例中,回风口200c设置在机壳200的下方,室内换热器400倾斜地设置,一方面倾斜设置可使室内换热器400与流经的气体能够有较大的换热面积,另一方面还可以减小从回风口200c进入的气流与室内换热器400的夹角,气流能够更顺畅地穿过室内换热器400,从而进一步提高换热效率。
导风结构100与机壳200连接,并设置在出风通道201a内,且靠近出风口200b处设置,用于引导出风口200b处的气流。为实现沿上下方向ZZ和沿左右方向XX改变气流方向,导风结构100包括导风板10和摆风叶片30,导风板10能够沿上下方向ZZ进行摆动,摆风叶片30能够沿左右方向XX进行摆动。
相关技术中,导风板和摆风叶片多采用分体独立组装的形式,例如,摆风叶片设置在导风板靠近风机的一侧,装配时,先将摆风叶片与机壳连接,再将导风板与机壳连接。为避免导风板和摆风叶片在摆动时相互干涉,导风板和摆风叶片之间有较大的距离,以预留充分的摆动空间。也就是说,导风板和摆风叶片在风道内不同的空间部分进行摆动,在前述的示例中,摆风叶片在导风板的上方空间进行左右摆动,导风板则在摆风叶片的下方空间进行上下摆动。可以理解地,相关技术中导风板和摆风叶片分体独立组装的结构形式占据较大的空间,当面对一些空调室内机(如天花机)需要超薄设计时,无法在缩小空间占用的同时保证导风板和摆风叶片的工作效果。
鉴于此,请参照图1和图2,在本申请的一些实施例中,导风结构100包括导风板10、多个摆风叶片30以及驱动组件50,驱动组件50用于驱使导风板10和多个摆风叶片30摆动。
本申请实施例中,驱动组件50包括第一驱动件51、第二驱动件53以及安装座55。
安装座55与机壳200连接,以为第一驱动件51和第二驱动件53提供安装基础。安装座55可采用金属制成,保证结构强度和支撑性;或者,安装座55也可采用塑料制成,便于生产和轻量化。可选地,安装座55大致呈盘状设置,具有位于中间部分的安装槽,第一驱动件51和第二驱动件53固定在安装槽内,安装座55的两侧则可通过螺钉连接、卡扣连接等可拆卸的连接方式与机壳200连接,保证安装座55的稳定性的同时,便于拆装。
第一驱动件51连接导风板10,并可驱动导风板10沿上下方向ZZ进行摆动。比如,第一驱动件51可以为步进电机,便于精确控制导风板10的摆动角度。具体地,第一驱动件51具有可绕沿第一方向延伸的轴线转动的输出端,本申请实施例中,第一方向与左右方向XX重合,导风板10与第一驱动件51的输出端连接,以使得第一驱动件51的输出端绕该轴线转动时,导风板10也可绕沿第一方向延伸的轴线转动,并以此实现上下方向的摆风。
第二驱动件53连接多个摆风叶片30,并可驱动多个摆风叶片30沿左右方向XX进行摆动。示例性地,第二驱动件53可选为直线电机或气缸,并具有可沿第一方向往复运动的输出端,多个摆风叶片30均与输出端连接而随之沿第一方向往复摆动。或者,第二驱动件53也可以采用具有可转动的输出端的步进电机,并通过传动的方式带动多个摆风叶片30摆动,以此实现左右方向的摆风,本申请实施例对此不作限制。
在一些实施例中,出风口200b大致为沿第一方向延伸的条状开口,与之相应地,导风板10沿第一方向延伸,以覆盖尽量多的出风口200b部分,保证导风效果。其中,导风板10可采用塑料一体注塑成型,生产效率较高,且重量较轻便于驱动。如图2所示,导风板10具有大致为长方形状的板体结构,其一端与第一驱动件51的输出端连接,以随第一驱动件51的输出端转动而改变导风板10自身与出风口200b处气流的夹角,从而进行上下摆风。比如,在图1所示的实施例中,出风口200b朝向机壳200的下方开口设置,若导风板10绕沿第一方向延伸的轴线顺时针转动,导风板10与出风口200b处的气流之间的夹角增大,导风板10一定程度阻挡气流向机壳200下方的运动,使之沿导风板10朝向机壳200的前侧流动。反之,若导风板10绕沿第一方向延伸的轴线逆时针转动,则导风板10与出风口200b处的气流之间的夹角减小,气流能够沿着导风板10向机壳200下方的流动。可以理解地,导风板10与气流的夹角越大,气流方向与上下方向ZZ之间的夹角便越大,便越发朝向机壳200的前方流动;而导风板10与气流的夹角越小,气流方向与上下方向ZZ之间的夹角便越小,便越发朝向机壳200的正下方流动。进一步地,为提高导风结构100的稳定性,导风板10远离安装座55的一端设有连接轴17,连接轴17与机壳200可转动地连接。如此,通过导风板10的摆动,能够调整出风口200b处气流在俯仰方向的流向,并可调整出风口200b处气流的覆盖范围。
多个摆风叶片30转动连接于导风板10的一侧,并沿第一方向间隔排布。摆风叶片30大致呈板状设置,并可采用塑料等材料制成。摆风叶片30的靠近导风板10的一侧通过转轴与导风板10连接,且摆风叶片30连接第二驱动件53的输出端。当第二驱动件53的输出端运动时,摆风叶片30可以上述转轴为转动中心,相对于导风板10绕上述转轴进行摆动。多个摆风叶片30间隔设置以将导风板10一侧的气流分成多个部分,多个摆风板在相对于导风板10进行转动时,气流沿摆风板进行运动而改变方向。示例性地,当多个摆风叶片30与前后方向YY平行时,从出风口200b处流出的气流能够大致沿前后方向YY流动;若多个摆风叶片30相对于导风板10向左摆动,则出风口200b处流出的气流偏向出风口200b的左侧流动,若多个摆风叶片30相对于导风板10向右摆动,则出风口200b处流出的气流偏向出风口200b的右侧流动。如此,通过设置多个摆风叶片30实现了沿左右方向XX的扫风。
需要说明的是,第一驱动件51和第二驱动件53是可独立运作的,因而可以是:
第一驱动件51工作,第二驱动件53不工作,此时导风板10摆动,多个摆风叶片30随导风板10沿其摆动方向运动,而多个摆风叶片30相对于导风板10静止,以在固定的左右方向的情况下,调整气流的俯仰角度;
第一驱动件51不工作,第二驱动件53工作,此时导风板10静止,多个摆风叶片30相对于导风板10左右摆动,以在固定的俯仰角度的情况下,调整气流的左右方向;
亦或者,第一驱动件51和第二驱动件53同时工作,则此时导风板10摆动,多个摆风叶片30随导风板10沿其摆动方向运动,且多个摆风叶片30相对于导风板10左右摆动,以同时调整气流的俯仰角度和左右方向。
其中,值得注意的是,相较于相关技术中摆风叶片30与导风板10分别独立设置的情况,本申请实施例的多个摆风叶片30与导风板10连接,取消了多个摆风叶片30与导风板10之间的空间间隔,使结构更加紧凑,从而能够提高空间利用率,减少多个摆风叶片30与导风板10所占用的空间,有利于空调室内机1000进行超薄设计。而由于多个导风叶片与导风板10转动连接,且导风板10和多个摆风叶片30分别通过第一驱动件51和第二驱动件53进行驱动,在导风板10进行摆动时,多个摆风叶片30也可相对于导风板10摆动而改变导风板10前侧的气流的流动方向,在减少占用空间的前提下,保证了导风板10和摆风叶片30的工作性能。
而且,相关技术中,出风口200b处的气流通常为先经过摆风叶片30调整左右方向,再流动至导风板10处调整俯仰方向,在这个先后过程中,扩散的气流可能会影响摆风叶片30的作用效果。本申请实施例中,由于多个摆风叶片30与导风板10相结合,使得导风结构100能够同时对导风板10前侧的气流进行俯仰方向和左右方向的调整。导风板10进行上下摆动时,多个摆风叶片30随之进行上下摆动,并可相对于导风板10进行左右摆动,能够扩大摆风叶片30的作用范围,在导风板10悬停的任意角度,摆风叶片30都能取得较好的扫风效果。且相较于相关技术,本申请实施例的多个摆风叶片30更靠近出风口200b,通过多个摆动叶片调整后的气流直接从出风口200b流出,能够进一步提高扫风效果,提高用户体验。
此外,相关技术中,由于导风板10和摆风叶片30是分开独立进行安装的,相应地,用于驱动导风板10运动的驱动源和用于驱动摆风叶片30运动的驱动源也需要独立地进行走线布置。本申请实施例中,第一驱动件51和第二驱动件53均设置在安装座55上,因而可集成连接线,便于导线连接。
更有,本申请实施例的导风结构100可生产为单独的空调室内机1000的构件,即在进行空调室内机1000的组装时,导风结构100能够作为独立的部件直接与机壳200进行连接。比如,在一些实施例中,将安装座55和导风板10另一端的连接轴17分别与机壳200进行连接,即可完成导风结构100的组装。提高空调室内机1000的模块化程度,便于调整装配工序,提升安装效率。
在一些结构形式中,面板202与壳体201可拆卸连接,并设有出风口200b,本申请实施例的导风结构100可与面板202连接,形成为面板组件。可选地,面板202上设有电控板,导风结构100与面板202连接时,驱动组件50的连接线与主控板电性连接,以通过主控板对驱动组件50进行总体控制。如此,在进行空调室内机1000的装配或安装时,将面板组件与壳体201整体地进行连接即可完成装配或安装,进一步提高效率。
在一些实施例中,导风板10和多个摆风叶片30可采用塑料材质,并分别一体注塑成型。导风板10可选为单个板体结构,多个摆风叶片30与导风板10转动连接。然而,由于导风板10沿第一方向的长度较大,在实际使用过程中容易发生变形且在气流作用下可能会产生较大幅度的振动,影响结构稳定性和导风性能。因此,请参照图2和图3,在本申请的另一些实施例中,导风板10包括第一板体11、第二板体13以及连接件15。
具体地,第二板体13与第一板体11间隔设置,且第二板体13与第一板体11大致平行。连接件15位于第一板体11和第二板体13之间,并连接第一板体11和第二板体13,第一驱动件51的输出端可连接第一板体11或第二板体13的一端,以在第一驱动件51的输出端运动时,第一板体11和第二板体13能够同步运动,气流能够沿第一板体11和第二板体13流动,且可从第一板体11和第二板体13之间穿过,以减少对气流的影响。多个摆风叶片30与第二板体13转动连接,以相对于第二板体13摆动。本申请实施例通过连接板连接间隔设置的两个板体,增加对两个板体的约束,从而有效减小导风板10的变形,提高导风板10的稳定性。
可选的是,第一板体11与第二板体13可采用相同或不同的材料制成,比如第一板体11为塑料材质,第二板体13为金属材质,第一板体11和第二板体13分别成型后通过连接件15进行连接;或者第一板体11、第二板体13以及连接件15可采用一体注塑成型,结构整体性好,稳定性高,且质量较轻,便于驱动。
请参照图3,可选地,定义与第一方向垂直的方向为第二方向,沿第二方向,第一板体11的宽度大于第二板体13的宽度。第二板体13设置在第一板体11沿第一方向的一侧,如此,第二板体13和连接件15能够对第一板体11起到加强作用,在减小第一板体11的变形,提高第一板体11的稳定性的同时,还能够进一步减小对出风口200b处气流的影响,提高导风效果。
本申请实施例中,连接件15大致呈板状设置,且连接件15沿前后方向YY延伸,以进一步减少对气流的阻碍,保证气流的顺畅性。
进一步地,结合图2,导风板10包括至少两个连接件15,至少两个连接件15沿第一方向间隔设置。一方面来说,通过设置至少两个连接件15能够进一步增加对第一板体11和第二板体13的约束,提高第一板体11和第二板体13的稳定性,减少变形;另一方面,至少两个连接件15可将从第一板体11和第二板体13之间流过的气流分成多个部分,能够对这部分气流起到梳理作用,使之便于引导,提高气流的稳定性。
结合图3和图4,本申请实施例中,摆风叶片30与第二板体13连接,多个摆风叶片30沿第一方向间隔地设置在第二板体13上。其中,沿第一方向,多个摆风叶片30可与多个连接件15间隔设置。比如,多个摆风叶片30可与多个连接件15交错设置,相邻两个连接件15之间设有一个摆风叶片30,相邻两个连接件15之间形成一导风通道,一摆风叶片30设置在导风通道内,如此,多个摆风叶片30可与多个连接件15配合将出风口200b处的至少部分气流分为较多细小的部分,便于引导气流流动,提高气流顺畅性。当然,在其他实施例中,多个摆风叶片30也可与多个连接件15一一对应设置,在本申请的改进构思下,本申请实施例对此不作限制。
如图4和图5所示,在一具体的实施例中,摆风叶片30设有第一插接柱36,第二板体13设有第一插接孔13a,第一插接柱36可转动地插设于第一插接孔13a内,以使得摆风叶片30能够相对于第二板体13绕第一插接孔13a的中心轴线进行摆动。其中,第一插接柱36设置在摆风叶片30靠近第二板体13的侧边,并包括第一柱体361和第一柱塞363。第一柱体361与摆风叶片30的主体部分连接,并沿远离主体部分的方向延伸设置,第一柱塞363设置在第一柱体361远离摆风叶片30的主体部分的一端。可选地,请参照图5,第一插接柱36可采用塑料等具有一定弹性的材料制成,并形成有沿自身延伸方向设置的豁口,这一豁口自第一柱塞363向第一柱体361延伸,使得第一柱体361和第一柱塞363分别被分隔为至少两部分,每一部分第一柱体361分别对应连接一部分第一柱塞363。可以理解地,自然状态下,第一柱塞363的至少两部分、第一柱体361的至少两部分均间隔设置,第一柱塞363的外径大于第一柱体361的外径,第一柱体361的外径略小于第一插接孔13a的内径;在将摆风叶片30连接至第二板体13时,可通过挤压第一柱塞363使第一柱塞363的至少两部分之间的距离减小,以将第一柱塞363伸入第一插接孔13a内,直至在预设的位置,比如第一柱塞363从第一插接孔13a穿出时,第一柱塞363由于自身弹性而恢复至自然状态,因而与第二板体13限位配合,使第一柱体361可稳定地设置在第一插接孔13a内,完成摆风叶片30的安装。进一步地,为提高插装效率,第一柱塞363还可设置成锥体或圆台的形状,且沿远离第一柱体361的方向,第一柱塞363的外径越来越小,倾斜的外表面可在第一柱塞363伸入第一插接孔13a时起到导向作用,便于插接。当然,在其他实施例中,还可以是第一柱塞363采用具有弹性的材料,比如橡胶材料一体成型,在进行插接时,第一柱塞363通过形变的方式深伸入第一插接孔13a内,并在穿出第一插接孔13a时恢复原状,以与第二板体13限位配合。如此,本申请实施例通过插装的方式实现将摆风叶片30连接至第二板体13,安装方式较为简单,便于提高生产效率。而可以理解的是,本申请实施例中摆风叶片30与第二板体13的连接方式不限于此,也可以是第二板体13设置插接柱,摆风叶片30设置插接孔等转动连接方式。
在如图3所示的实施例中,第二板体13的宽度小于第一板体11且位于第一板体11的一侧。其中,第一插接孔13a可设置在第二板体13靠近第一板体11的中部的一侧,第一插接柱36设置在摆风叶片30的中间部分,这样摆风叶片30能够对中地安装在导风板10上,保证摆风叶片30的稳定性和摆风范围,且便于摆风叶片30与第二驱动件53的连接。
结合图1,如前所述,导风结构100设置在出风通道201a内,并靠近出风口200b处设置,摆风叶片30设置在机壳200形成出风口200b的前后两侧壁之间。在空调室内机1000运行时,导风板10旋出而使得出风口200b打开,气流能够从出风口200b处流出。在一实施例中,为避免摆风叶片30与出风口200b处的前侧壁相干涉,在导风板10摆动时,摆风叶片30的外边缘与出风口200b的侧壁之间具有距离L,且满足关系:L≥2.5mm。可以理解地,若是L小于2.5mm,由于制造公差,导风板10摆动时,摆风叶片30可能会刮擦出风口200b的前侧壁,这样不仅会产生噪音、影响机壳200使用寿命,还会导致导风板10运行不够顺畅,不便于精确操控,影响导风效果。因此,为避免上述问题,本申请的这一实施例设置摆风叶片30的外边缘与出风口200b的侧壁之间的距离L≥2.5mm,L可选为3mm、3.5mm等,以避免摆风叶片30与出风口200b处侧壁的相互干涉,保证导风板10运动的顺畅性。
在一实施例中,摆风叶片30包括相连接的弧形段31和延伸段33。弧形段31与第二驱动件53和第二板体13连接,具体地,第一插接柱36设置在弧形段31靠近第二板体13的一侧,以使弧形段31转动连接于第二板体13。弧形段31的远离第二板体13的一端向第一板体11的另一侧延伸设置,以扩大摆风范围,延伸段33设置在弧形段31这一远离第二板体13的一端。
导风板10通过连接轴17与机壳200转动连接,因而具有穿过连接轴17并沿第一方向延伸设置的转动轴线。可选地,连接轴17与第二板体13连接,转动轴线穿过第二板体13。
请再次参照图3,可以理解地,空调室内机1000处于运行状态时,导风板10需至少维持一定的出风口200b的开度,以使气流能够顺场地自出风口200b流出。在导风板10摆动时,弧形段31的外边缘与出风口200b处的前侧壁间隔设置。一实施例中,弧形段31的外边缘呈圆弧状设置,且其弧心靠近转动轴线设置或位于转动轴线上。如此,摆风叶片30随导风板10运动时,弧形段31的外边缘与出风口200b处的前侧壁之间的距离变化较小或保持不变。一方面来说,本申请实施例能够有效避免弧形段31的外边缘与出风口200b处的前侧壁相干涉,进一步保证了导风结构100的运行顺畅性;另一方面,由于弧形段31的外边缘与出风口200b处的前侧壁之间的距离变化较小或保持不变,无论导风板10在任何角度悬停,摆风叶片30都能保证最大的摆风范围,从而保证了摆风效果。进一步地,摆风叶片30的转动中心与弧心重合,能够进一步提高摆风效果。
本申请实施例中,由于第一板体11和第二板体13间隔设置,二者之间有着高度差,延伸段33设置在第二板体13沿第一方向的一侧,以至少能够对第一板体11和第二板体13之间的气流进行导向,保证摆风效果。而可以理解地,相较于直接将摆风叶片30与第一板体11连接,通过将弧形段31与第二板体13进行连接能够有效缩短摆风叶片30的外边缘与转动中心的距离,提高摆风叶片30摆动时的稳定性。换个角度讲,延伸段33与延伸段33的一端连接,且与弧形段31形成一设置在延伸段33一侧的缺口,第二板体13位于该缺口处,在保证摆风效果的同时,摆风叶片30与导风板10的结合较为紧凑,进一步减少占用空间。
进一步地,如图3所示,本申请实施例中,延伸段33与弧形段31的一端连接,并沿弧形段31端部的切线延伸设置。可以理解地,倘若延伸段33仍是沿绕弧形段31的圆弧延伸设置,则延伸段33靠近第一板体11的部分较窄,在摆动时的作用范围较小。因此,本申请实施例中的延伸段33具有沿弧形段31端部的切线延伸设置,使得延伸段33具有较大的摆风面积,能够持续地对气流进行导向,摆风效果较好。当然,延伸段33也可不沿弧形段31端部的切线延伸,或可沿相较于弧形段31的外边缘曲率较小的弧进行延伸,以保证延伸段33的摆风效果,在此不再赘述。
在出风口200b处,出风口200b的气流流动从层流向湍流过渡,容易形成较大的涡旋,较为影响气动性能,且可能会产生噪音。为此,在本申请一实施例中,摆风叶片30的外边缘设有扰流部,扰流部被配置为供气流穿过摆风叶片30。示例性地,摆风叶片30的外边缘设有沿自身周向间隔设置的多个扰流孔,扰流孔可以为圆形孔或多边形孔,如四边形孔、六边形孔等,且每一扰流孔均贯穿摆风叶片30设置,以使得本实施例中的摆风叶片30在进行摆动时能够使一部分气流穿过扰流孔,将原本随着尾迹耗散的较大涡流提前打碎,从而减少噪音,提升气动性能。
或者,在另一实施例中,扰流部包括设置在摆风叶片30的外边缘的多个齿结构35,多个齿结构35沿摆风叶片30的周向间隔设置。相邻两个齿结构35之间形成有齿形槽,多个齿形槽沿摆风叶片30的周向间隔排布,在摆风叶片30摆动时,气流能够穿过多个齿形槽,以实现减少涡旋和降低噪音的效果。本实施例中的多个齿结构35在保证摆风作用的同时,便于摆风叶片30边缘处的气流的横向流动,降噪效果较好。
本申请实施例中,齿结构35的截面形状可为三角形、矩形、梯形、半圆形或半椭圆形,对此不作限定。如图6所示,在其中一具体的实施例中,齿结构35的齿高为H,满足关系:1.5mm≤H≤4mm。可以理解地,在摆风叶片30的尺寸规格一定的情况下,齿高越高,摆风叶片30外边缘部分便具有越深的齿形槽,摆风面积越小;齿高越低,摆风叶片30外边缘部分便具有越浅的齿形槽,摆风面积越大。故若是齿高H大于4mm,则可能会显著减少摆风叶片30的摆风面积,影响摆风效果;若是故若是齿高H小于1.5mm,则齿形槽可能过浅,不能很好的起到扰流作用,不利于降低噪音。综上,本申请实施例为在保证摆风效果的同时,达到降噪的目的,限定1.5mm≤H≤4mm,齿高H可选为2mm、3mm等。
齿结构35宽度为D,满足关系:1.5mm≤D≤3mm。可以理解地,在摆风叶片30的尺寸规格一定的情况下,宽度越大,摆风叶片30外边缘部分便具有越窄的齿形槽,摆风面积越大;宽度越小,摆风叶片30外边缘部分便具有越宽的齿形槽,摆风面积越小。故若是宽度D大于3mm,则可能会使得齿形槽可能过窄,不能很好的起到扰流作用,不利于降低噪音;若是宽度D小于1.5mm,则齿形槽可能过宽,显著减少摆风叶片30的摆风面积,影响摆风效果。综上,本申请实施例为在保证摆风效果的同时,达到降噪的目的,限定1.5mm≤D≤3mm,齿高H可选为2mm、2.5mm等。
进一步地,多个齿结构35的节距角为Φ,满足关系:9°≤Φ≤15°。可以理解地,在摆风叶片30的尺寸规格一定的情况下,节距角越大,多个齿结构35越稀疏,摆风叶片30外边缘部分便具有越宽的齿形槽,摆风面积越小;节距角越小,多个齿结构35越密,摆风叶片30外边缘部分便具有越窄的齿形槽,摆风面积越大。故若是节距角Φ大于15°,则则齿形槽可能过宽,显著减少摆风叶片30的摆风面积,影响摆风效果;若是节距角Φ小于9°可能会使得齿形槽可能过窄,不能很好的起到扰流作用,不利于降低噪音。综上,本申请实施例为在保证摆风效果的同时,达到降噪的目的,限定9°≤Φ≤15°,节距角Φ可选为10°、13°等。
当然,扰流部还可以采用其他可能的结构形式,在一些未图示的实施例中,扰流部也可设置为波浪状。也就是说,扰流部包括设置在摆风叶片30外边缘的多个波纹,多个波纹沿摆风叶片30的周向延伸,并沿摆风叶片30的厚度方向起伏。如此,摆风叶片30不再为一平板结构,而是因波纹在自身的厚度方向上有高低的起伏,因而在摆风叶片30摆动时能够起到更好的破风效果,从而减小噪音。
在一些实施例中,为提高空调室内机1000运行时的使用舒适性,导风板10的摆动角度范围为α,满足关系50°≤α≤60°。需要说明的是,此处导风板10的摆动角度范围所指的是空调室内机1000运行时,导风板10的活动范围。举例来说,在空调室内机1000运行时,以水平线为参考,导风板10可在与水平线呈20°至20°+α夹角的范围内摆动。可以理解地,若是α小于50°,则气流的覆盖范围可能不够,调节效果不理想;若是α大于60°,则气流可能会直吹下方,可能会使人体感到不适。因此,为保证调节效果和舒适性,本申请实施例限定50°≤α≤60°,α可选为55°、53°等。
进一步地,摆风叶片30向导风板10一侧的摆动角度范围为β,满足关系30°≤β≤45°。需要说明的是,此处摆风叶片30的摆动角度范围所指的是空调室内机1000运行时,摆风叶片30的活动范围。举例来说,在空调室内机1000运行时,以竖直线为参考,摆风叶片30可在与竖直线呈-β至β的范围内摆动。可以理解地,若是β小于30°,则气流的横向覆盖范围可能不够,调节效果不理想;若是β大于45°,则摆风叶片30对气流的阻挡作用较强,不利于出风顺畅性且可能会产生噪音。因此,为保证调节效果,并保证出风顺畅性,降低噪音,本申请实施例限定30°≤β≤45°,β可选为35°、40°等。
除上述摆风叶片30分体设置并分别独立转动连接导风板10的结构形式,在另外的结构形式中,导风结构100还包括连接座,连接座与多个摆风叶片30为一体结构。连接座与导风板10可拆卸连接,比如,为便于拆装,连接座与导风板10可采用卡扣连接。摆风叶片30可相对于连接座发生弹性形变,以在连接座与导风板10连接时,在第二驱动件53的驱动下进行摆动。可选地,摆风叶片30和连接座可采用PP(Polypropylene,聚丙烯)一体注塑成型,以保证良好的变形特性。可以理解地,通过拆装连接座能够快速地完成多个摆风叶片30的拆装,提高工作效率,且多个摆风叶片30与连接座一体成型能够提高生产效率。
为使多个摆风叶片30同步摆动,多个摆风叶片30可传动连接,第二驱动件53设置在多个摆风叶片30的一侧,并驱动其中一个摆动叶片摆动,这一摆动叶片通过传动的方式带动其余的摆风叶片30运动。
在本申请的其他实际例中,驱动组件50还包括传动组件57,传动组件57连接于第二驱动件53的输出端,并与多个摆风叶片30连接,以驱动多个摆风叶片30相对于导风板10同步摆动。
结合图7,具体地,传动组件57包括导向杆571、套接件573以及传动杆575。
导向杆571连接于第二板体13,并沿第一方向延伸设置。套接件573滑动套接于导向杆571,并与第二驱动件53连接,第二驱动件53可驱动套接件573而沿导向杆571滑动。为提高结构集成度,导向杆571连接于第二板体13靠近安装座55的一端,并与第一板体11间隔设置,以缩短套接件573与第二驱动件53的距离,便于结构布置。
传动杆575与第二板体13间隔设置,并沿第一方向延伸设置,传动杆575连接套接件573,且多个摆风叶片30均与传动杆575可转动地连接。其中,套接件573被第二驱动件53驱动而沿导向杆571滑动时,能够带动传动杆575至少沿第一方向平移,并带动多个摆风叶片30相对于导风板10摆动。
本申请实施例第二驱动件53通过套接件573和传动杆575同时驱动多个摆风叶片30进行摆动,能够提高多个摆风叶片30的同步性。此外,通过套接件573与导向杆571的配合可以提高传动杆575的稳定性,进而使多个摆风叶片30的运动更为稳定,进一步提高摆风效果。
可选地,传动杆575靠近第二驱动件53的一端设有第一连接部5751,套接件573包括滑套5731和第二连接部5735,滑套5731套设于导向杆571,并与第二驱动件53的输出端连接,第二连接部5735与滑套5731连接。第一连接部5751和第二连接部5735中的二者之一设有连接槽5735a,连接槽5735a沿与第一方向呈夹角的方向延伸设置,其中之另一设有连接柱,连接柱穿设于连接槽5735a,并可沿连接槽5735a的延伸方向滑动。如此,在滑套5731和第二连接部5735沿导向杆571运动时,第一连接部5751随之运动,并带动传动杆575运动,进而带动多个摆风叶片30摆动,结构简单有效,便于将第一驱动件51和第二驱动件53集成在安装座55上。
在一实施例中,摆风叶片30靠近第二板体13的一侧设有避位槽,导向杆571活动穿设于避位槽,不仅提高导向杆571的稳定性也能使结构更为紧凑,进一步减少空间占用。
在一具体的实施例中,摆风叶片30设有第二插接柱37,传动杆575设有第二插接孔575a,第二插接柱37可转动地插设于第二插接孔575a内,以使得摆风叶片30能够相对于传动杆575转动。其中,第二插接柱37可设置在避位槽内,并包括第二柱体371和第二柱塞373。第二柱体371与摆风叶片30的主体部分连接,并沿远离主体部分的方向延伸设置,第二柱塞373设置在第二柱体371远离摆风叶片30的主体部分的一端。可选地,请参照图5,第二柱塞373可采用具有弹性的材料,比如橡胶材料一体成型。自然状态下,第二柱塞373的外径大于第二柱体371的外径,第二柱体371的外径略小于第二插接孔575a的内径;在将摆风叶片30连接至传动杆575时,可通过挤压第二柱塞373使第二柱塞373通过形变的方式深伸入第二插接孔575a内,直至在预设的位置,比如第二柱塞373从第二插接孔575a穿出时,第二柱塞373由于自身弹性而恢复至自然状态,因而与传动杆575限位配合,使第二柱体371可稳定地设置在第二插接孔575a内,完成摆风叶片30的安装。进一步地,为提高插装效率,第二柱塞373还可设置成锥体或圆台的形状,且沿远离第二柱体371的方向,第二柱塞373的外径越来越小,倾斜的外表面可在第二柱塞373伸入第二插接孔575a时起到导向作用,便于插接。或者,在其他实施例中,第二插接柱37可采用塑料等具有一定弹性的材料制成,并形成有沿自身延伸方向设置的豁口,这一豁口自第二柱塞373向第二柱体371延伸,使得第二柱体371和第二柱塞373分别被分隔为至少两部分,每一部分第二柱体371分别对应连接一部分第二柱塞373。由此,第二柱塞373和第二柱体371可通过减少间隔的方式弹性伸缩,实现快速拆装。如此,本申请实施例通过插装的方式实现将摆风叶片30连接至传动杆575,安装方式较为简单,便于提高生产效率。而可以理解的是,本申请实施例中摆风叶片30与传动杆575的连接方式不限于此,也可以是传动杆575设置插接柱,摆风叶片30设置插接孔等转动连接方式。
在一实施例中,为驱动套接件573运动,第二驱动件53的输出端设有传动齿轮531,套接件573(滑套5731)的外侧设有沿第一方向延伸的齿条5733结构,齿条5733结构具有沿导向杆571的周向延伸的齿槽573a,传动齿轮531与齿条5733结构相啮合,传动齿轮531转动以驱动套接件573沿导向杆571滑动。本实施例中通过齿轮和齿条5733的传动方式具有较高的可靠性,且能够将第二驱动件53的输出端的旋转运动转化为套接件573的直线运动,使得第二驱动件53可选用步进电机等便于精确控制的驱动源,且便于第二驱动件53在安装座55内的排布,使驱动组件50的结构更紧凑。此外,齿条5733结构的每个齿均沿导向杆571的周向延伸,而形成多个沿导向杆571的周向延伸的齿槽573a,如此,在导风板10转动时,套接件573随之转动,并确保此时传动齿轮531的齿仍位于齿槽573a内,提高传动连接的稳定性。而在本申请的其他实施例中,第二驱动件53也可采用连杆结构等驱动套接件573运动,本申请实施例对此不作限制。
以上内容主要解释说明了本申请导风结构100的具体实现方式,可以理解地,由于本申请其他方面提出的面板组件、空调室内机1000以及暖通系统均采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有效果,在此不再一一赘述。
