本发明提出一种空调室内机壳体。
在本发明实施例中，如图1至图4所示，该空调室内机壳体，包括呈中空半球状设置的前壳1，以及与前壳1的开口端连接的背板2，
前壳1与背板2围合形成一容腔3；前壳1的上部沿前后方向设有多个进风口121，前壳1的下部设有出风口122；
进风口121的边缘处向前壳1内设有向下延伸的导流板（41,42），导流板用以将进风导向空调室内机的换热器100。
壳体用以为空调室内机的内部部件如换热器100、送风组件等提供防护，并围合形成部分的风道300；壳体一般为注塑件，前壳11并不限于严格意义的半球形，它可以是类球状的壳体，一般不限于1/2，可以为0~1之间的任意靠近1/2的值。
尽管优选地，导流板设置在进风口121的边缘处，但实际上，将导流板设置在进风口121的中间也是可以的，同样可以起到导流的作用。
本发明空调室内机壳体通过在壳体的内侧设置导流板，以在对从不同进风口121进入的空气隔离的同时，对该进入的空气进行导流，从而将换热前的空气导向至换热器100的不同区域，由此，换热器100能得到均匀的换热，进而提升了换热器100的换热效率。
进一步地，请一并参照图5至图9，在一实施例中，导流板包括第一翼板41及第二翼板42，第一翼板41设置在相邻的两进风口121之间，第二翼板42设置在进风口121的左右边缘处。
在本实施例中，由于进风口121设置在球形的前壳1上，因此，为了增大进风面积，通常进风口121左右方向上的长度大于前后方向上的宽度，从而相对而言，起主要导流作用的是第一翼板41，第二翼板42可以防止气流从左右两侧泄露，从而保证气流从换热器100中流过。优选地，设于各进风口121左右边缘处的第二翼板42依次相接。如此，可以更好地围合进风气流，并将进风气流导引至换热器100。
进一步地，第一翼板41的宽度沿左右方向逐渐变窄。在本实施例中，由于进风口121一般为左右方向长，因而中部的风量较大，从而所需的导流长度也较长。此外，由于换热器100上端的轮廓线一般呈水平延伸，由此，换热器100上端与前壳1之间就围合形成一个半月形的安装空间。因此，通过将第一翼板41设置呈中间宽，两边窄，一方面，可以将进风充分地导向至换热器100的设定区域；另一方面可以防止第一翼板41与换热器100干涉，并使空调室内机的内部结构更为紧凑。
进一步地，所进风口121为格栅状，进风口121的格栅上设有连接第一翼板41的加强筋123。在本实施例中，由于第一翼板41具有一定的宽度，并凸出前壳1的内壁面设置，在将第一翼板41与前壳1一体设置并注塑成型的实施例中，这种结构如果不设置加强筋123，则第一翼板41在脱模或装运的过程容易发生折断，装配至空调室内机后也容易在振动及气流的共同作用下振动，导致噪音的产生。
进一步地，前壳1的上部沿前后方向设有数道台阶形凹部124，凹部124均包括互成角度设置的第一台阶面125及第二台阶面126，第一台阶面125以及邻近背板2设置的第二台阶面126上设有进风口121。
在本实施例中，未设置进风格栅的第二台阶面126可以形成导流的作用，因此，进风风流不易发生抢风，从而可提升进风效率。此外，各凹部124的第一台阶面125，以及邻近背板2、最靠后的第二台阶面126上开设进风格栅，在保证进风面积的前提下，前壳1的球面可以对邻近的第一台阶面125形成遮蔽、靠前的一凹部124的第二台阶面126可以对应邻近且靠后的一凹部124的第一台阶面125形成遮蔽，从而形成在空调室内机壳体的前方无法看到空调室内机内部的结构的外观效果，尽量减少了进风格栅的设置对外观的影响。
进一步地，第一翼板41形成在第一台阶面125与第二台阶面126的交接处。在本实施例中，由于凹部124的第一台阶面125与第二台阶面126的互成角度设置，因此，两台阶面的交接处实际上最为靠近换热器100，如此，第一翼板41可以作为第一台阶面125和或第二台阶面126的延伸，更好地将风导向至换热器100。
进一步地，前壳1包括本体11及上盖12，本体11的上部形成有缺口111，上盖12盖合于缺口111处，各凹部124的中段形成在上盖12上，第二翼板42形成在上盖12的左右边缘处。在本实施例中，由于具有各凹部124中段的部位结构复杂，若与前壳1的其他部位一体成型则势必增加制造难度，并且在增加注塑模具复杂度的同时，还难以保证成品率。单独制造具有各凹部124中段的上盖12，则可以相应地降低制造难度。
进一步地，远离背板2的第一台阶面125的前边缘处设有向下延伸的檐板127，檐板127位于本体11的内侧，并与邻近的本体11的内壁面成一夹角设置。在本实施例中，从邻近本体11的进风口121进入的风，本体11的内壁面由于距离换热器100较远，并且弧度较大，因此无法起到将风导向换热器100的作用；并且，进入本体11球顶处的风也无法很好的换热。通过设置檐板127，则可以将从邻近邻近本体11的进风口121进入的风导向至换热器100，提高了换热器100前侧的空气流量，从而使换热器100整体换热更均匀。
本发明还提出一种壁挂式空调室内机，包括空调室内机壳体，该空调室内机壳体的具体结构参照上述实施例，由于本壁挂式空调室内机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有益效果，在此不再一一赘述。其中，壁挂式空调室内机的换热器100、贯流风轮200设置的连通进风口121与出风口122的风道300中。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
