下面将参考附图并结合实施例来详细说明本发明。
实施例一
请参阅图1-10所示，本公开实施例提供一种过滤网连接结构，包括：
过滤网1，过滤网1的下边框上设有向外凸起的滤网把手14；
中框2，过滤网1安装在中框2上；
连接结构，包括连接板3和插接结构，连接板3与滤网1连接，插接结构分别与连接板3和中框2连接。
连接结构用于连接滤网1与中框2，连接结构包括连接板3，连接板3设置在滤网1的下边框的下边缘上，并在与下边框垂直的方向向外凸出设置一滤网把手14，滤网把手14与连接板3相交于下边框的边缘。连接板3的设置，增大了滤网把手14下方的空间，便于对滤网把手14施力进行滤网1的拆装。另外，中框2的下部还设有用于与底座螺钉连接的螺钉孔22，中框2的下部还设有用于与面板卡扣连接的卡扣23，本实施例中螺钉孔22位于中框2上与被连接板3遮挡的区域。已知技术中卡扣与螺钉孔位于中框下部上的同一条线上，美观度不足，本公开实施例将螺钉孔22的位置上移至中框上被连接板3遮挡的区域，这样在安装好过滤网1后，从中框2外面看过去，螺钉孔22的位置是隐藏不可见的，提高了美观性，且由于螺钉孔22在中框2上的位置上移，使得中框2与底座的固定更加牢靠；另外，由于螺钉孔22位于卡扣23的上方，当面板与中框2卡扣连接时，因为配合产生装配间隙，从装配间隙直吹的冷热风不会吹到螺钉孔22以及安装在螺钉孔22位置的螺钉，防止螺钉发生锈蚀。
本公开实施例还提供一种空调器，包括底座及面板，还包括上述滤网连接结构，中框2与底座之间采用螺钉固定，面板与中框2卡扣连接，中框2上设有导向槽，滤网1通过导向槽安装在中框2上且从中框2的前部弧形延伸至中框2的顶部，使得滤网1在中框2顶部弯曲成弧形。这里需要理解的是，滤网1本身并非弧形，而是安装到中框2上后受弯曲而成弧形。如图4所示，中框2还包括中框本体以及位于中框本体上的支撑件21，支撑件21包括设置在中框本体的进风口中部的第一加强筋，以及位于中框本体的进风口两侧的第二加强筋，以提高中框2的强度。
如图2-3所示，过滤网1包括左右对称设置的两个滤网单元，滤网单元包括方形框架10，在方形框架10内设有相互间纵横交错的多个横向筋11和多个纵向筋12，多个横向筋11沿滤网1的上下方向间隔开设置，多个纵向筋12沿滤网1的左右方向间隔开设置，使得多个横向筋11和多个纵向筋12 之间限定出多个过滤孔13，过滤孔13上罩设有网面。
两个滤网单元左右并列安装在中框2上，两个滤网单元中的横向筋11是贯穿滤网1的左右两侧的整体的、连续的筋条，如此设置，一方面能够提高滤网1的整体强度，另一方面还增加滤网1的整体美观性。
方形框架10由依次首尾连接的上边框、右边框、下边框及左边框连接，上边框及下边框与多个纵向筋12连接，左边框与右边框与多个横向筋11连接。在下边框的前表面上向外凸设有一滤网把手14，滤网把手14与下边框的边缘垂直，且滤网把手14从滤网1的左侧一直延伸到滤网1的右侧，形成一条连续的长条形板，如此设置，一方面大大增加了滤网把手14的面积，有助于滤网1的拆装，另一方面也提高了滤网1的整体美观性。
滤网把手14整体呈矩形状，滤网把手14的长度与滤网1在左右方向的宽度一致，滤网把手14向外凸起的宽度不超过支撑件21向远离空调器方向凸出的厚度，即滤网把手14向外伸出的部分与支撑件21外表面齐平或低于支撑件21向外伸出的部分，如此设置，不仅有助于降低中框2与空调面板之间需要满足的安装空间要求，且增加美观性。
如图6-9所示，连接结构包括第二连接板31，第二连接板31包括由滤网1下边框向下延伸一定高度且厚度均匀的矩形板。矩形板的一端与滤网把手14垂直连接，另一端设置有向靠近中框2方向垂直弯折的折边板32。
中框2上设有用于容纳连接板的凹槽，凹槽包括第二凹槽，在第二连接板31弯折处，折边板32紧贴在第二凹槽的侧壁，使得第二连接板31在弯折处与中框2抵接，且第二连接板31的外表面与中框2的外表面平齐，当滤网1安装在中框2上时，第二连接板31与中框2之间没有落差，避免因落差产生台阶，不美观且台阶易刮手，存在安全隐患。
插接结构包括插片33和与插片33配合的通孔24，插片33与连接板3连接，通孔24设置在中框2上。本实施例中在折边板32上垂直设置若干插片33，插片33为矩形薄板，在折边板32与第二凹槽抵接的第二凹槽侧壁上开设若干与插片33配合的通孔24，插片33插入通孔24中，第二连接板31固定在中框2上，进而将滤网1固定在中框2上，且该插片33与通孔24隐藏在中框2内，从外面仅能看到第二连接板31与中框2平齐，增加美观性。
第二连接板31与中框2之间由于设置了折边板32，使得第二连接板31 与中框2之间形成了一个条形槽25，为了提高中框2的强度以及中框2对第二连接板31的支撑，在条形槽25内，将中框2设置成台阶状，台阶的形状不作限制，可以设置成连续垂直折弯的台阶，也可以设置成如图6所示的包括直板和斜板的台阶。将位于条形槽25内的中框2设置成台阶形状，能够增大条形槽25内的中框2与第二连接板31之间的接触面积，进而提高中框2对第二连接板31的支撑强度。
本公开实施例提供的滤网连接结构，包括设置在滤网1下边框上的连续长条形滤网把手14，以及将滤网1与中框2连接起来的隐藏式的连接结构，一方面加大了滤网把手的受力面积和操作空间，便于滤网的拆卸，一方面隐藏式的连接结构，增加了美观性。
实施例二
本实施例与实施例一的不同之处在于，如图10-13所示，本实施例中，连接板3包括由下边框底面向下延伸设置的具有一定高度的第一连接板34，第一连接板34的高度h也即如图12所示方位中第一连接板34在上下方向具有的尺寸，第一连接板34的高度h根据螺钉孔22的位置确定，以能够覆盖住螺钉孔22为宜。第一连接板34还具有一定的厚度，该厚度c1是指如图12所示方位中第一连接板34在前后方向具有的尺寸。
第一连接板34沿远离滤网把手14方向的厚度逐渐增大，即第一连接板34靠近滤网把手端的厚度c11较薄，第一连接板34远离滤网把手端的厚度c12较厚，第一连接板34沿上下方向的截面为一直角梯形，使得第一连接板34的外侧表面为一倾斜面，第一连接板34的外侧表面如图11中所示的第一连接板的前表面。
由于第一连接板34在靠近滤网把手14端的厚度c11低于远离滤网把手14端的厚度c12，因此滤网把手14与第一连接板34相接处，滤网把手14相对于第一连接板34向滤网1外表面凸起的宽度尺寸更大，当操作者使用滤网把手14时具有更大的操作空间，便于手握住滤网把手14以及对滤网把手14施加作用力。
凹槽还包括与第一连接板34远离滤网把手14的一端抵接的第一凹槽，第一凹槽在如图11所示方位的前后方向的宽度b2与第一连接板34位于第一凹槽内的厚度一致，使得第一连接板34的外表面与中框2的外表面平齐，避 免由于第一连接板34在第一凹槽内的厚度与凹槽宽度b2不一致产生落差，造成中框2与第一连接板34之间具有台阶，不美观且台阶易刮手，存在安全隐患。
第一连接板34与中框2的连接方式类似，均采用插片与通孔插接的方式，具体的，在第一连接板34远离滤网把手14的一端设置若干插片33，并在中框2上设置与插片33配合的通孔24，实现滤网1与中框2的连接，二者装配后，插片33被中框2遮挡在内侧，从外面看，插片33是隐藏不可见的，增加了美观性。
本实施例设置的连接结构3，设置了厚度渐变的第一连接板34，并在第一连接板上34设置插片结构，实现了滤网1与中框2的隐藏式连接，同时还增大了滤网把手14的操作空间，便于滤网1的拆卸。
实施例三
本实施例在实施例一的基础上，在滤网把手14的上表面设置防滑部，以增加手与滤网把手14之间的摩擦，便于操作者握住滤网把手14并向其施加作用力。防滑部可以是防滑纹，在滤网把手14的上表面沿滤网1横向方向设置防滑纹，防滑部也可以是在滤网把手14上凸设的圆形凸点，或者是在滤网把手14的上表面上沿滤网1横向方向均匀设置凹槽，拆装时将手指置于凹槽内，同时对滤网的方形框架10框架施加作用力，使得滤网方形框架10弯曲变形，从而将滤网1拆下或装上。可以理解的是，防滑部的形状和结构并不限于上述设置。
以上所述仅为本公开的可选实施例，对本公开而言仅仅是说明性的，而非限制性的。本专业技术人员理解，在本公开权利要求所限定的精神和范围内可对其进行许多改变，修改，甚至等效，但都将落入本公开权利要求的保护范围内。
