技术领域
本申请涉及空调技术领域，尤其涉及一种空调室内机。
背景技术
空调设备一般都在其外壳的出风侧设置有出风框，而为保证出风框的拆装和维修的便利性，出风框一般是可拆卸地安装于空调设备外壳。
相关技术中，为保证出风框的安装稳固性，出风框一般是通过长螺钉柱连接于空调设备外壳，这样，在安装时，往往需要搬动空调设备外壳，并将外壳对正出风框以实现安装，即也就是，出风框相对于外壳只能接受被动安装，这样便会造成出风框的安装变得耗时费力，降低了出风框的安装效率。
申请内容
本申请的目的在于提供一种空调室内机，旨在解决现有技术中的出风框与空调设备外壳的安装耗时费力，效率低下的技术问题。
本申请实施例提供一种空调室内机，所述空调室内机的相对两侧分别为出风侧和背风侧，所述空调室内机包括面板组件和插设于所述面板组件上的出风框，所述出风框的长度方向定义为第一维度，所述出风框的宽度方向定义为第二维度，垂直于所述第一维度与所述第二维度形成的平面定义为第三维度，所述面板组件形成有安装通腔，所述安装通腔靠近所述出风侧设置，所述出风框安装于所述安装通腔处，所述面板组件于所述安装通腔的边缘设置有装配条，所述装配条上开设有第一通口及第二通口，所述出风框的边缘设置有卡勾及插板，所述卡勾穿过所述第一通口并勾接于所述装配条之外以限制所述出风框在所述第三维度上的移动，所述插板插入所述第二通口并在所述第二通口内滑动并使所述插板的前端夹紧于所述第二通口在插入方向上的前端，所述插板限制所述出风框在所述第一维度和所述第二维度上的移动。
在一些实施例中，所述第二通口包括第一子通口和与所述第一子通口连通的第二子通口，所述插板穿过所述第一子通口并夹紧于所述第二子通口在插入方向的前端，所述第一子通口呈渐收口设置，所述渐收口的开口方向背离所述插板的插入方向设置。
在一些实施例中，所述装配条上开设有至少一个限位孔，所述出风框朝向所述装配条的一侧设置有至少一个凸钮，于所述插板的前端夹紧于所述第二通口在所述插板的插入方向上的前端后，各所述凸钮分别弹性卡设于各所述限位孔内。
在一些实施例中，所述卡勾朝向所述装配条的一侧形成有导引面，于所述插板插设于所述第二通口内时，所述导引面引导所述装配条与所述卡勾相抵接。
在一些实施例中，所述卡勾包括连接板和勾接板，所述连接板设置于所述出风框的边缘，所述勾接板设置于所述连接板背离所述出风框的一侧，且所述勾接板穿过所述第一通口并勾接于所述装配条之外，所述导引面形成于所述勾接板朝向所述第一通口的一侧。
在一些实施例中，所述第一通口沿所述第一维度方向开设于所述装配条上，所述勾接板和所述第一通口的配合方向与所述插板和所述第二通口的插入方向相同。
在一些实施例中，所述插板设置于所述连接板上，所述第一通口和所述第二通口相连通。
在一些实施例中，所述插板和所述连接板间隔设置，所述第一通口和所述第二通口间隔设置。
在一些实施例中，所述连接板朝向所述装配条的一侧凸起延伸形成有限位筋，所述限位筋于所述勾接板穿过所述第一通口并勾接于所述装配条之外时抵撑于所述安装通腔的内侧壁。
在一些实施例中，所述连接板背离所述插板的一侧凸起延伸形成有至少一条加强筋。
在一些实施例中，所述勾接板和所述插板之间设置有固定板。
在一些实施例中，所述出风框包括外框板和主框体，所述外框板安装于所述主框体上，所述卡勾和所述插板均设置于所述外框板的边缘，所述外框板沿其宽度方向的一侧设置有侧框板，所述侧框板和所述主框体之间形成有装配间隙，所述卡勾和所述插板均位于所述装配间隙内。
本申请实施例提供的空调室内机中的上述一个或多个技术方案至少具有如下技术效果之一：本申请实施例提供的空调室内机，在出风框装设于面板组件的安装通腔的过程中，设置于出风框边缘的卡勾和插板分别插设于安装通腔边缘处设有的装配条上开设的第一通口和第二通口内，如此，卡勾穿过第一通口并勾接于装配条之外便可限制了出风框远离或靠近面板组件的运动，即也就是第三维度的运动，而插板在插入第二通口后，可在第二通 口内滑动，且插板的前端能够夹紧于第二通口于其插入方向的前端，这样插板与第二通口的配合，一方面限制了出风框沿其长度方向上的移动，另一方面也限制了出风框沿其宽度方向上的运动。即也就是，插板与第二通口的配合，限制了出风框沿第一维度和第二维度运动的能力。如此，卡勾和插板分别与第一通口和第二通口的配合便实现了对出风框相对于面板组件的多自由度的限制。这样，本申请实施例提供的空调室内机，通过卡勾和插板分别与第一通口和第二通口的配合便无需借助螺钉而实现了出风框于面板组件上的可拆卸连接，同时，又由于卡勾和插板分别与第一通口和第二通口的配合限制了面板组件多自由度的限制，这样也保证了出风框装设于面板组件上的可靠性。那么由于无需借助螺钉实现出风框的安装，这样便可实现出风框相对于面板组件的主动安装，从而节省了安装耗时，实现了省力安装，提高了安装效率。

如图1～3和图5所示，本申请实施例的一个实施例中，提供一种空调室内机10，空调室内机10具有出风侧11及与出风侧11相对的背风侧12，空调室内机10具有第一维度、第二维度和第三维度，空调室内机10包括面板组件13和插设于面板组件13上的出风框14，出风框14的长度方向定义为第一维度，出风框14的宽度方向为第二维度，垂直于第一维度与第二维度形成的平面定义为第三维度，面板组件13形成有安装通腔131，安装通腔131靠近出风侧11设置，出风框14安装于安装通腔131处，面板组件13于安装通腔131的边缘设置有装配条132，装配条132上开设有第一通口133及第二通口134，出风框14的边缘设置有卡勾141及插板142，卡勾141穿过第一通口133并勾接于装配条132之外以限制 出风框14在第三维度上的移动，插板142插入第二通口134并在第二通口134内滑动并使插板142的前端夹紧于第二通口134在插入方向上的前端，插板142限制出风框14在第一维度和第二维度上的移动。其中，本文所述的“前”可以参照图8所示，且图8展现的是卡勾141及插板142均未插配到位的状态。
具体地，卡勾141和第一通口133均可以为一个或者多个，当卡勾141和第一通口133均为多个时，各卡勾141均设于出风框14的外边缘并总体呈环状分布(例如在图4所示的示例中，出风框14的上下两侧分别有沿左右方向间隔开分布的多个卡勾141，出风框14的左右两侧可以不具有卡勾141)，各第一通口133均开设于装配条132上并总体呈环状分布(例如在图2所示的示例中，装配条132的上下两侧分别有沿左右方向间隔开分布的多个第一通口133，装配条132的左右两侧可以不具有第一通口133)，各卡勾141分别和各第一通口133一一对应设置，且每个卡勾141与对应的第一通口133的装配方向相同。
同理地，插板142和第二通口134也均可以为一个或者多个，当插板142和第二通口134均为多个时，各插板142均设于出风框14的外边缘并总体呈环状分布(例如在图4所示的示例中，出风框14的上下两侧分别有沿左右方向间隔开分布的多个插板142，出风框14的左右两侧可以不具有插板142)，各第二通口134均开设于装配条132上并总体呈环状分布(例如在图2所示的示例中，装配条132的上下两侧分别有沿左右方向间隔开分布的多个第二通口134，装配条132的左右两侧可以不具有第二通口134)，各插板142分别和各第二通口134一一对应设置，且每个插板142与对应的第二通口134的装配方向相同。
在将出风框14装配于面板组件13的过程中，由于卡勾141和插板142均固定在出风框14上，因此，插板142和卡勾141是联动的(即同步运动的)，从而在将插板142于第二通口134内滑动并使插板142的前端夹紧于第二通口134的过程中，卡勾141与插板142同步滑动，从而卡勾141可以完成穿过第一通口133并勾接于装配条132的动作，如此，出风框14的外周便能够通过卡勾141穿过第一通口133并与装配条132的勾接配合而牢牢地装设于面板组件13上。
本申请实施例提供的空调室内机10，在出风框14装设于面板组件13的安装通腔131的过程中，设置于出风框14边缘的卡勾141和插板142分别插设于安装通腔131边缘处设有的装配条132上开设的第一通口133和第二通口134内，如此，卡勾141穿过第一通口133并勾接于装配条132之外便可限制了出风框14远离或靠近面板组件13的运动，即也就是第三维度的运动，而插板142在插入第二通口134后，可在第二通口134内滑动，且插板142的前端能够夹紧于第二通口134于其插入方向的前端，这样插板142与第二通口134 的配合，一方面限制了出风框14沿其长度方向上的移动，另一方面也限制了出风框14沿其宽度方向上的运动。
即也就是，插板142与第二通口134的配合，限制了出风框14沿第一维度和第二维度运动的能力。如此，卡勾141和插板142分别与第一通口133和第二通口134的配合便实现了对出风框14相对于面板组件13的多自由度的限制。这样，本申请实施例提供的空调室内机10，通过卡勾141和插板142分别与第一通口133和第二通口134的配合便无需借助螺钉而实现了出风框14于面板组件13上的可拆卸连接，同时，又由于卡勾141和插板142分别与第一通口133和第二通口134的配合限制了面板组件13多自由度的限制，这样也保证了出风框14装设于面板组件13上的可靠性。那么由于无需借助螺钉实现出风框14的安装，这样便可实现出风框14相对于面板组件13的主动安装，从而节省了安装耗时，实现了省力安装，提高了安装效率。
在本申请的一个实施例中，如图3和图5所示，该空调室内机的第二通口134包括第一子通口135和与第一子通口135连通的第二子通口136，插板142穿过第一子通口135并夹紧于第二子通口136在插入方向的前端，第一子通口135呈渐收口设置，渐收口的开口方向背离插板142的插入方向设置，也就是说，沿着插板142的插入方向，第一子通口135的口径逐渐减小。具体地，通过使得第二通口134包括第一子通口135和第二子通口136，并使得第一子通口135开设有朝向背离插入方向设置的渐收口，这样插板142在插设于第二子通口136的过程中便会首先进入到第一子通口135，并得到渐收口的导向作用，这样便保证了插板142能够顺畅地插设于第二子通口136内。而通过使得插板142夹紧于第二子通口136在插入方向的前端，这样便实现了插板142相对于装配条132的限位，进而实现对出风框14相对于面板组件13在第一维度和第二维度上的限位。
在本申请的一个实施例中，如图3～5所示，该空调室内机的装配条132上开设有至少一个限位孔137，出风框14朝向装配条132的一侧设置有至少一个凸钮143，各凸钮143均于插板142的前端夹紧于第二通口134在插板142的插入方向上的前端后分别弹性卡设于各限位孔137内。具体地，通过上述设置，这样在出风框14在装配于面板组件13的过程中，当插板142的前端夹紧于第二通口134在插入方向上的前端后，此时由于插板142和卡勾141是联动的，卡勾141也完成了穿过第一通口133并勾接于装配条132，此时凸钮143便会随同出风框14的整体运动而移动至限位孔137内，并实现卡设于限位孔137中，那么凸钮143在弹性卡设于限位孔137时，必然会产生声响，操作人员即可通过听声判断出风框14和面板组件13是否装配到位，这样便实现了出风框14相对于面板组件13的盲 装。
在本申请的一个实施例中，如图5和图8所示，该空调室内机的卡勾141朝向装配条132的一侧形成有导引面144，导引面144于插板142插设于第二通口134内时引导装配条132与卡勾141相抵接。具体地，导引面144为倾斜面，且导引面144和第二通口134的孔边的夹角为钝角。这样导引面144既能够随同出风框14整体相对于面板组件13的移动而抵接于第二通口134的孔边并相对于第二通口134的孔边发生滑动，这样便带动了卡勾141的相邻于导引面144的上端面在导引面144离开第二通口134的孔边后，紧紧抵接于第二通口134的孔边，这样便实现了卡勾141与装配条132的较为紧固的勾接配合。同时，由于装配条132多为钣金件，而钣金件在实际装配过程中易发生曲挠变形，那么由于卡勾141与装配条132实现了较为紧密的勾接配合，这样也保证了装配条132固有的钣金变形能够得到有效抑制。
在本申请的一个实施例中，如图5所示，该空调室内机的卡勾141包括连接板145和勾接板146，连接板145设置于出风框14的边缘，勾接板146设置于连接板145背离出风框14的一侧，且勾接板146穿过第一通口133并勾接于装配条132之外，导引面144形成于勾接板146朝向第一通口133的一侧。具体地，连接板145沿第二维度设置于出风框14的边缘，勾接板146沿第一维度设置于连接板145沿第二维度的一侧。
在本申请的一个实施例中，如图5所示，第一通口133沿第一维度方向开设于装配条132上，勾接板146和第一通口133的配合方向与插板142和第二通口134的插入方向相同。这样勾接板146和第一通口133的配合方向便与出风框14的长度方向处于相同维度，从而使得出风框14便能够沿其长度方向滑动设置于面板组件13上，而由于其长度方向的边缘具有足够的设置卡勾141和插板142的装配空间，这样便使得卡勾141和插板142的数量能够适当地增多，进而增加出风框14和面板组件13的安装稳定性。
在本申请的一个实施例中，如图5所示，该空调室内机的插板142设置于连接板145上，第一通口133和第二通口134相连通。具体地，通过使得插板142设置于连接板145上，第一通口133和第二通口134相连通，这样插板142和卡勾141便为一体成型件，而第一通口133和第二通口134也可一次制作完成，这样便降低了出风框14的整体制造成本。同时，通过将插板142与连接板145相连，这样也提高了插板142和连接板145的强度，有效降低了插板142或连接板145装配时发生意外折断的几率。
在本申请的一个实施例中，如图5所示，该空调室内机的插板142设置于连接板145上设置有勾接板146的同侧并与勾接板146间隔设置。具体地，通过使得插板142和勾接 板146同侧设置，这样便也保证了两者分别与第一通口133和第二通口134的配合方向相同，避免相互干涉。而使得插板142和勾接板146在连接板145上间隔设置，这样也保证了插板142和勾接板146避免相互干涉。
在本申请的一个实施例中，如图5所示，该空调室内机的插板142和连接板145间隔设置，第一通口133和第二通口134间隔设置。具体地，通过使得插板142和连接板145间隔设置，且使得第一通口133和第二通口134间隔设置，这样便能够使得出风框14与面板组件13的装配位置均匀分散，进而保证了出风框14的各处受力均匀，不易发生应力集中的现象。
在本申请的一个实施例中，如图5所示，该空调室内机的连接板145朝向装配条132的一侧凸起延伸形成有限位筋147，限位筋147于勾接板146穿过第一通口133并勾接于装配条132之外时抵撑于安装通腔131的内侧壁。具体地，由于限位筋147的存在，且限位筋147能够抵撑于安装通腔131的内侧壁，这样限位筋147便能够保证安装通腔131的内侧壁不会发生钣金变形，进而保证了安装通腔131内壁上设置的装配条132的装配位置不发生改变，进而提升了出风框14与面板组件13的装配精确性。
在本申请的一个实施例中，如图5所示，该空调室内机的连接板145背离插板142的一侧凸起延伸形成有至少一条加强筋148。具体地，通过在连接板145上设置加强筋148，这样便得以提升了连接板145的整体强度，进而保证了设置于其上的插板142和勾接板146的稳定性。
在本申请的一个实施例中，如图6～8所示，该空调室内机的出风框14包括外框板15和主框体16，外框板15安装于主框体16上，卡勾141和插板142均设置于外框板15的边缘。
在本申请的一个实施例中，如图6～8所示，外框板15沿其宽度方向一侧设置有侧框板151，侧框板151和主框体16之间形成有装配间隙152，卡勾141和插板142均位于装配间隙152内。
在本申请的一个实施例中，如图6～8所示，外框板15长度方向的相对两端还设置有翻盖板17。
在本申请的一个实施例中，如图6～8所示，卡勾141和插板142之间设置有固定板149。
具体地，由于侧框板151的存在，这样位于侧框板151一侧的卡勾141和插板142即可通过设置于侧框板151与主框体16之间所形成的装配间隙152内而实现隐藏化安装，一方面保护了卡勾141和插板142，另一方面也提升了出风框14的整体美观度。同时，外框 板15上开设有用于安装于导风格栅的装配通腔153，装配通腔153与安装通腔131相连通。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
