Description

一种底壳结构及包括该底壳结构的空调器 技术领域
本公开涉及空调技术领域，特别涉及一种底壳结构及包括该底壳结构的空调器。
背景技术
壁挂式的空调内机由底壳、换热器组件、面板体、面板、导风门组成。底壳是支撑其他零件装配的基体，空调器的换热器组件横截面为多段折弯式结构，且多段折弯结构形成一凹形，并留有一凹口。为了防止制冷制热过程中，换热器组件的凹口处漏风，底壳需要把换热器组件的凹口围起来。为适应换热器组件的形状，底壳的形状通常也为带有凹口的多段折弯式结构，且底壳凹口与换热器组件凹口相对设置，并将换热器组件凹口囊括，以形成包围状态。而底壳的这种折弯结构，在模拟运输、跌落过程中，折弯处容易发生断裂。一方面，断裂造成空调损坏，导致额外的售后维护费用；另一方面，断裂未被发现会导致漏风，从而产生凝露水，影响空调制冷制热效果，造成售后反馈等一系列问题。此外，现有底壳结构下所形成的进风路径较长，风阻以及折弯角度大，影响进风顺畅度和进风量，易造成喘振噪音，影响用户体验。

需要说明的是，在本公开的实施例中所提到的所有的方向或位置关系 为基于附图的位置关系，仅为了方便描述本公开和简化描述，而不是明示或者暗示所指的装置或元件必须具有的特定的方向和位置关系，不能理解为对本公开的限制。文中所述的“第一”和“第二”是用于区别类似的对象，并不是用于描述先后次序。
在本公开的一个实施例中，提供了一种底壳结构，用于实现与空调换热器组件的装配，如图1-2所示，底壳结构包括：
第一迎风面3，用于对风进行汇聚或阻拦。
第二迎风面4，与所述第一迎风面3相交，使风沿着所述第一迎风面3向所述第二迎风面4流动，从而使风向发生改变。
本实施例中，第一方向为第一迎风面3和第二迎风面4的长度方向，即左右方向，如图1所示的x轴方向。第一迎风面3的第二方向为其高度方向，即与其左右方向垂直的上下方向，如图1所示的y1轴方向。第二迎风面4的第二方向为其高度方向，即与其左右方向垂直的上下方向，如图1所示的y2轴方向。在本实施例中，第一迎风面3和第二迎风面4为平板结构，且二者的长度方向相互平行。第二迎风面4与所述第一迎风面3相交是指：第一迎风面3长度方向的一个侧边与第二迎风面4长度方向的一个侧边相连接。
若干第二加强筋2，其构造为短筋状结构，设置于所述第一迎风面3与所述第二迎风面4相交的折弯处，为同时垂直于所述第一迎风面3与所述第二迎风面4的片状结构。
若干第一加强筋1，为根部与所述第二迎风面4连接，整体倾斜设置于所述第二迎风面4上，并由所述第二迎风面4朝向所述第一迎风面3一侧延伸的条形结构；所述第一加强筋1所在平面与所述第二加强筋2所在平面垂直设置，所述第二加强筋2介于所述第一加强筋1、所述第一迎风面3与所述第二迎风面4所限定的区域之间。
所述第二加强筋2设置于所述第一迎风面3与所述第二迎风面4相交的折弯处，第二加强筋2对第一迎风面3与第二迎风面4起到支撑加固作用。当折弯处由于碰撞挤压等因素而有断裂的倾向时，由于第二加强筋2的存在，使得加强折弯处的强度被加强，从而防止折弯处发生断裂。
所述第二加强筋2与所述第一加强筋1、所述第一迎风面3和所述第 二迎风面4均接触连接，所述第一加强筋1与所述第二加强筋2以及折弯处配合，能够形成稳固的三角形结构，三角形结构可以进一步加强折弯处的强度。优选的，所述第二加强筋2在同时垂直于第一迎风面3与第二迎风面4的平面的截面为三角形。可以进一步加强对折弯处的支撑加固作用，提高折弯处的强度。
在一个示例中，所述第一加强筋1所在平面与所述第一迎风面3之间的夹角为0-10°；优选地，所述第一加强筋1与所述第一迎风面3平行设置，即夹角为0°，进而方便在注塑过程中进行出模。
本实施例的底壳结构，所述第一加强筋1与所述第二加强筋2的配合使用，一方面，对底壳结构容易发生断裂的折弯处进行加强，有效防止底壳的弯曲变形，同时防止空调在模拟运输或者跌落过程中造成的折弯处的断裂破坏；另一方面，所述第一加强筋1和所述第二加强筋2形成互补结构，使自身的强度均得到有效地增强，避免单独存在造成的结构不稳定。由于所述第一迎风面3和所述第二迎风面4交汇处的圆弧设计，使风从所述第一迎风面3向所述第二迎风面4流动时，在相交处可以有更好的过渡，避免风向的突变，从而使进风路径更加顺畅，达到降噪的效果。
在一个示例中，结合图1和图2所示，所述第一加强筋1在第一方向，即长度方向上为间断布置，在间断处设置有若干凸出部5，所述凸出部5分布于所述第一迎风面3与所述第二迎风面4的折弯处，并与所述第一迎风面3和所述第二迎风面4均接触连接，并且所述凸出部5在第一方向，即长度方向的两侧与所述第一加强筋1接触连接。优选地，凸出部5在第一迎风面3的高度大于第二加强筋2在第一迎风面3投影的高度，凸出部5在第二迎风面4的高度大于第一加强筋1在第二迎风面4投影的高度。凸出部5的厚度大于第一加强筋1顶端与第一迎风面3的距离。其中，所述厚度方向为前后方向，如图2所示的与x轴与y1轴垂直的z1轴方向，为第一迎风面3的厚度方向；与x轴与y2轴垂直的z2轴方向，为第二迎风面4的厚度方向。所述顶端是指第一加强筋1远离第二迎风面4的端部。
所述凸出部5和所述第一加强筋1的配合，可以有效地对折弯处的强度进一步进行加强，并且凸出部5在高度和厚度的尺寸均大于第一加强筋1、第二加强筋2，可以对折弯处提供更强的支撑和加固。同时，与所述第 一加强筋1的接触连接，可以防止所述第一加强筋1长度过长导致的稳定性降低的问题发生。
在一个示例中，结合图1和图2所示，多个所述第二加强筋2沿长度方向阵列分布于所述第一迎风面3与所述第二迎风面4的折弯处，多个所述第二加强筋2间隔设置，所述第二加强筋2的数量随着所述第一加强筋1的长度的增加而增加，所述第一加强筋1长度越长，所述第二加强筋2数量越多，数量众多且阵列分布的第二加强筋2使所述折弯处的强度得到进一步提升。优选地，多个第二加强筋2在长度方向上均匀分布，这样可以为折弯处提供均匀的支撑和加固，有利于使折弯处的强度均匀全面的提升。
在本公开的另一个实施例中，提供了一种底壳结构。为了简要起见，以下重点描述其不同于前述实施例的特征，与前述实施例相同或相似的特征不再赘述。
结合图3、图4、图5所示，所述第一迎风面3和所述第二迎风面4的夹角为A，在注塑过程中，所述第一迎风面3与出模面垂直设置，即所述第二迎风面4与所述出模面的夹角为A-90°；所述第一加强筋1所在平面与所述第二迎风面4的夹角为B。
当所述夹角B与所述夹角A满足关系式A+B＝180°时，所述第一加强筋1与所述出模面垂直，出模效果达到最佳。优选的，B的取值范围为20°≤B≤50°。
结合图4所示，倘若所述底壳结构上没有设置所述第一加强筋1和所述第二加强筋2，空调机的进风路径为S1，进风路径S1沿着所述第一迎风面3和所述第二迎风面4流动，在出风口处风向发生了急剧变化，因此产生了较大的喘振噪音。本实施例的底壳结构，设置所述第一加强筋1和所述第二加强筋2后，空调机的进风路径为S2；所述第一加强筋1角度使风的进风路径发生改变，增加进风的顺畅度，减小进风产生的喘振噪音。
所述第一加强筋1的角度使风向提前发生了小幅度改变，使风流出时在出风口缓慢过渡，进风路径S2相较于S1有了较好改善，有效地降低了噪音。
在一个示例中，所述第一加强筋1上任一点到所述第一迎风面3的最 大垂直距离为G，其中，G的取值范围为3mm≤G≤5.5mm。由于所述第一加强筋1上任一点到所述第一迎风面3的最大垂直距离越大，对进风的阻拦量越大。如果最大垂直距离过大会导致进风量不足或者使风回流。经试验发现，所述第一加强筋1上任一点到所述第二迎风面4的最大垂直距离优选为3mm到5.5mm时，进风路径S2的顺畅度最佳，噪音也相对较低。
所述第一加强筋1的厚度为D，其中，D的取值范围为1.2mm≤D≤3mm，所述厚度D是指垂直于第一加强筋1所在平面方向上的长度。当所述第一加强筋1的厚度过大时，会造成材料不必要的浪费；当所述第一加强筋1的厚度过小时，由于强度不足，往往会导致材料的脆断，尤其在所述第一加强筋1与所述第二加强筋2的交汇处。所述第一加强筋1的厚度为1.2mm到3mm时，所述第一加强筋1可以达到较佳的强度。
所述第一加强筋1的高度为H，所述高度H是指垂直于长度方向和所述厚度D的方向的长度。所述第一加强筋1将进风路径S1改变为S2，使风向水平方向偏转的距离为E，即所述第一加强筋1的顶端至所述第一迎风面3的距离为E，水平方向偏转距离E的计算公式为：
Figure PCTCN2019081729-appb-000001
即：E＝sinB·H   (2)
其中，B为所述第一加强筋1所在平面与所述第二迎风面4的夹角；H为所述第一加强筋1的高度。
在本公开的又一实施例中，提供了一种空调器，所述空调器包括上述任一实施例所述的底壳结构。
上所述仅为本发明的优选实施例而已，并不用以限制本公开，凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
需要说明的是，本公开实施例中提到的方向用语，例如“顶”、“底”、“上”、“下”、“前”、“后”、“左”、“右”等，仅是参考附图的方向，并非用来限制本公开的保护范围。实际上，本公开中提到的“顶”、“底”可以被替换为“第一方向”、与“第一方向”相对的“第二方向”，“顶端”、“底端”可以被替换为“第一端”、与“第一端”相对的“第二端”，“顶部”、 “底部”可以被替换为“第一端部”、与“第一端部”相对的“第二端部”。与此类似，本公开中的“上”、“下”，“前”、“后”，“左”、“右”也同样可以做上述替换。
