Description

空调壳体和室内机 技术领域
本实用新型涉及空调技术领域，具体而言，涉及一种空调壳体和室内机。
背景技术
目前，零风感空调为了增大出风量，提升换热效率，除出风口外还增加了面板出风通道。由于增加了面板出风通道，使面板与中框悬空，使得此类空调在常规模式运行下，导风门开启，中框从用户视觉上存在漏黑现象，从结构上存在密封不严，存在不防虫鼠的问题，影响用户观感体验和整机密闭性；此外由于面板与中框悬空，使得此类空调在常规模式运行下，存在风吹到面板导致面板振动，产生噪音的问题。
实用新型内容
本实用新型解决的问题是：导风门开启，中框从用户视觉上存在漏黑现象，而且密封不严，存在不防虫鼠的问题，影响用户观感体验和整机密闭性。
为解决上述问题，第一方面，本实用新型提供一种空调壳体，应用于室内机，空调壳体包括：
中框，开设有出风口；
出风面板，安装在中框的外侧、且位于出风口的上方，出风面板与中框之间形成出风道，出风道与出风口连通；
格栅结构，安装在出风道的入口处，出风口吹出的气流经过格栅结构进入出风道。
本实用新型提供的空调壳体的有益效果包括：
1.在出风面板与中框之间形成的出风道的入口处安装格栅结构，在导风门开启的情况下，从用户视觉上，出风道的入口不存在漏黑现象，用户会直接观赏到格栅结构，提升空调壳体的美观度和用户的观感体验；
2.出风道的入口处安装格栅结构可以有效防止虫鼠进入出风道，提高空调壳体的密闭性；
3.格栅结构可以降低出风口吹出气流进入出风道的流速，避免气流吹到出风面板的底部边缘、造成出风面板的底部边缘振动，减少噪音的产生，提升设备使用的可靠性和用户体验；
4.增设格栅结构，也不会降低室内机的出风量，对室内机的制冷效果几乎没有影响，也基本不会增加凝露的可能性。
在可选的实施方式中，格栅结构上开设有多个条形孔，条形孔垂直于中框的长度方向，多个条形孔沿中框的长度方向间隔均匀设置。
这样布置条形孔，可以使格栅结构上的孔隙率(孔隙率＝条形孔的总面积/格栅结构的面积)较大，使格栅结构对气流的阻挡影响较小，而且，每个条形孔的长度不会太大，降低生产难度。
在可选的实施方式中，条形孔的宽度a为：2mm～5mm，相邻两个条形孔的距离b为：1.5mm～2.5mm。
在可选的实施方式中，条形孔位于格栅结构宽度方向上的中部位置，条形孔与格栅结构宽度方向的边缘的距离c为：1.5mm～2.5mm。
在可选的实施方式中，格栅结构的厚度d为：1.5mm～2.5mm。
格栅结构的尺寸按照上述参数设计，不仅能够保证格栅结构上的孔隙率较大，还能够保证格栅结构具有足够的结构强度。
在可选的实施方式中，中框上、位于出风道的入口处开设有安装槽，格栅结构靠近中框的一端安装在安装槽内。
这样，可以提高格栅结构安装在中框上的稳定性，也避免格栅结构受气流的吹动而产生振动噪音。
在可选的实施方式中，安装槽沿格栅结构厚度方向的深度e大于或等于格栅结构的厚度d，安装槽沿格栅结构宽度方向的深度f小于或等于条形孔与格栅结构宽度方向的边缘的距离c。
这样，格栅结构的厚度d不超过安装槽的深度e，避免格栅结构在厚度方向上凸出安装槽、形成尖端，也就避免气流吹到尖端上造成音噪。条形孔与格栅结构宽度方向的边缘的距离c不超过安装槽的深度f，避免格栅结构上的条形孔被中框遮挡，使全部条形孔完全能够通过气流。
在可选的实施方式中，空调壳体还包括：
基座，设置在出风面板的底部，基座与中框之间形成出风道的入口，格栅结构靠近出风面板的一端搭接在基座上。
这样，不仅进一步提高格栅结构安装的稳定性，而且，出风面板的底部边缘与出风口之间被基座间隔，使出风面板的底部边缘与出风口距离增加，避免出风面板的底部边缘被出风口的气流直吹，降低出风面板受气流吹拂而振动的可能性。
在可选的实施方式中，基座通过支架连接在中框上，出风面板的底端搭接在基座上，出风面板的顶端连接在中框上。
这样，基座和出风面板安装的稳定性较高。
第二方面，本实用新型提供一种室内机，室内机包括：
前述实施方式的空调壳体；
导风门，安装在出风口，导风门的底端可转动的连接在中框上。
这样，本实用新型提供的室内机采用上述空调壳体，提升了室内机的美观度和用户的观感体验，提高了室内机的密闭性，减少了噪音的产生，提升了设备使用的可靠性和用户体验，对出风量、制冷效果以及凝露基本没有不利影响。

具体实施方式
为使本实用新型的上述目的、特征和优点能够更为明显易懂，下面结合附图对本实用新型的具体实施例做详细的说明。
请参阅图1和图2，本实施例提供一种室内机100，室内机100包括空调壳体2和导风门1，其中，空调壳体2包括中框21、出风面板22、格栅结构23和基座24。
具体的，中框21上开设有出风口211，图2中出风口211内的箭头表示出风方向。导风门1安装在出风口211，导风门1的底端可转动的连接在中框21上。
出风面板22安装在中框21的外侧、且位于出风口211的上方，出风面板22与中框21之间形成出风道25，出风道25与出风口211连通。出风面板22上开设有用于出风的通孔。
格栅结构23安装在出风道25的入口处，出风口211吹出的气流经过格栅结构23进入出风道25。
这样，在出风面板22与中框21之间形成的出风道25的入口处安装格栅结构23，在导风门1开启的情况下，从用户视觉上，出风道25的入口不存在漏黑现象，用户会直接观赏到格栅结构23，提升空调壳体2的美观度和用户的观感 体验；还可以有效防止虫鼠进入出风道25，提高空调壳体2的密闭性；还可以降低出风口211吹出气流进入出风道25的流速，避免气流吹到出风面板22的底部边缘、造成出风面板22的底部边缘振动，减少噪音的产生，提升设备使用的可靠性和用户体验；增设格栅结构23，也不会降低室内机100的出风量，对室内机100的制冷效果几乎没有影响，也基本不会增加凝露的可能性。
请参阅图2和图3，基座24设置在出风面板22的底部，基座24与中框21之间形成出风道25的入口，格栅结构23靠近出风面板22的一端搭接在基座24上。具体的，基座24通过支架连接在中框21上，出风面板22的底端搭接在基座24上，出风面板22的顶端连接在中框21上。这样，不仅提高格栅结构23安装的稳定性，而且，出风面板22的底部边缘与出风口211之间被基座24间隔，使出风面板22的底部边缘与出风口211距离增加，避免出风面板22的底部边缘被出风口211的气流直吹，降低出风面板22受气流吹拂而振动的可能性。
请参阅图3，中框21上、位于出风道25的入口处开设有安装槽212，格栅结构23靠近中框21的一端安装在安装槽212内。这样，可以提高格栅结构23安装在中框21上的稳定性，也避免格栅结构23受气流的吹动而产生振动噪音。
优选地，安装槽212沿格栅结构23厚度方向的深度e大于或等于格栅结构23的厚度d(请参阅图5)，安装槽212沿格栅结构23宽度方向的深度f小于或等于条形孔231与格栅结构23宽度方向的边缘的距离c(请参阅图4)。这样，格栅结构23的厚度d不超过安装槽212的深度e，避免格栅结构23在厚度方向上凸出安装槽212、形成尖端，也就避免气流吹到尖端上造成音噪。条形孔231与 格栅结构23宽度方向的边缘的距离c不超过安装槽212的深度f，避免格栅结构23上的条形孔231被中框21遮挡，使全部条形孔231完全能够通过气流。
本实施例中，安装槽212的形式为L形缺口，在其它实施例中，安装槽212的形式也可以是U形缺口，U形缺口的开口宽度大于或等于格栅结构23的厚度，使格栅结构23可以直接***U形缺口，也能够对格栅结构23起到稳定支撑的效果。
请参阅图4，格栅结构23上开设有多个条形孔231，条形孔231优选为腰形孔，条形孔231垂直于中框21的长度方向，多个条形孔231沿中框21的长度方向间隔均匀设置。这样布置条形孔231，可以使格栅结构23上的孔隙率(孔隙率＝条形孔231的总面积/格栅结构23的面积)较大，使格栅结构23对气流的阻挡影响较小，而且，每个条形孔231的长度不会太大，降低生产难度。
条形孔231的宽度a为：2mm～5mm，优选a为3mm，相邻两个条形孔231的距离b为：1.5mm～2.5mm，优选b为2mm。条形孔231位于格栅结构23宽度方向上的中部位置，条形孔231与格栅结构23宽度方向的边缘的距离c为：1.5mm～2.5mm，优选c为2mm。
格栅结构23的总长度可以根据出风道25的入口的长度确定，优选格栅结构23的总长度大于或等于出风道25的入口的长度。格栅结构23的总宽度可以根据出风道25的入口的宽度确定，优选格栅结构23的总宽度大于或等于出风道25的入口的宽度。这样，可以保证格栅结构23完全覆盖出风道25的入口，完全避免用户视觉上的漏黑现象。
在其它实施例中，格栅结构23上还可以开设圆孔、椭圆孔、菱形孔、矩形孔或其它规则形状的通孔，也可以是不规则的通孔，同样也能一定程度地起到本实施例中的技术效果。
请参阅图5，格栅结构23的厚度d为：1.5mm～2.5mm，优选d为2mm。
格栅结构23的尺寸按照上述参数设计，不仅能够保证格栅结构23上的孔隙率较大，还能够保证格栅结构23具有足够的结构强度。
当然，在其它实施例中，格栅结构23也可以不按照上述参数设计，只要能够部分或全部地覆盖出风道25的入口，都能一定程度地起到本实施例中的技术效果。
本实施例提供的空调壳体2的有益效果包括：
1.在出风面板22与中框21之间形成的出风道25的入口处安装格栅结构23，在导风门1开启的情况下，从用户视觉上，出风道25的入口不存在漏黑现象，用户会直接观赏到格栅结构23，提升空调壳体2的美观度和用户的观感体验；
2.出风道25的入口处安装格栅结构23可以有效防止虫鼠进入出风道25，提高空调壳体2的密闭性；
3.格栅结构23可以降低出风口211吹出气流进入出风道25的流速，避免气流吹到出风面板22的底部边缘、造成出风面板22的底部边缘振动，减少噪音的产生，提升设备使用的可靠性和用户体验；
4.增设格栅结构23，也不会降低室内机100的出风量，对室内机100的制冷效果几乎没有影响，也基本不会增加凝露的可能性；
5.利用基座24和中框21上的安装槽212来支撑格栅结构23，提高格栅结构23安装的稳定性，避免格栅结构23受气流吹拂而产生振动噪音。
虽然本实用新型披露如上，但本实用新型并非限定于此。任何本领域技术人员，在不脱离本实用新型的精神和范围内，均可作各种更动与修改，因此本实用新型的保护范围应当以权利要求所限定的范围为准。
