技术领域
本发明涉及家用电器技术领域，尤其涉及一种过滤网装置及空调。
背景技术
随着人们生活水平的提高，空调已成为我们生活中不可缺少的一部分。由于空调属于换风设备，用户需要经常清洗过滤网，以避免积累尘污的滋生霉菌影响其身体健康。
现有空调过滤网为软态结构，存在以下不足：
1、现有的空调过滤网分开为左右两件置于机器内部，清洁时一般需要先打开面板，再将过滤网拉出清洗，抽出过滤网的操作较为复杂，不够方便。
2、现有的空调过滤网的滑槽多为上下式，在抽取或按照空调过滤网时，因为柔性结构的空调过滤网与滑槽中滑动是存在与滑槽形状不一致的张力，这就使得上下方向抽拉过程容易将灰尘抖落，影响用户体验。
3、清洗完成后，软态结构的空调过滤网在与滑槽装配时，因为滑槽的弧度问题，装入机器内部时容易装不到位，且在安装过程中也会因为硬性碰撞损坏空调过滤网。

具体实施方式
下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
实施例1
本发明提供了一种过滤网装置，如图1-7所示，包括：设置在机壳1的过 滤网组件2，所述机壳1为安装有过滤网装置的机器的外壳，如图4-5所示，所述过滤网组件2包括一体式的直板型过滤框架21，所述机壳1上设置有自锁开关3，所述过滤网组件2的边框上设置有与自锁开关3相配合的卡块24，所述过滤网组件2在自锁开关3和卡块24的配合下在机壳1上锁紧或释放。
如图6-7所示，所述自锁开关3包括锁壳31、锁芯32和抵接在锁芯32上的自锁组件33，所述自锁组件33包括连接在锁壳31底部的呈U型的弹性挂钩331，所述锁壳31底部和锁芯之间还连接有复位弹簧323。所述锁芯32上开设有锁合道321和与锁合道321相连接的锁合块322，所述锁合道321在接近锁合块322处分叉出至少一条绕过所述锁合块322的岔道，所述锁合块322上远离弹性挂钩331的一侧开设有用于卡挂锁合块322的缺口，所述弹性挂钩331随锁芯32推进而挂卡在锁合块322上，随锁芯32的退出在复位弹簧323的作用下沿岔道返回至锁合道321上。复位弹簧323的设置，保证了自锁开关3在受到触发后迅速将锁芯32弹出，避免了用户触发后还要用手将锁芯32抽出，操作更为方便快捷。
所述自锁组件33在外力触发下能锁紧锁芯32、再次施加外力能释放锁芯32，所述锁芯32的外侧还连接有与卡块24相配合的卡口324，所述卡口324的上下侧随锁壳31挤压而闭合，随锁壳31离开而张开。所述卡口324可以是可上下摆动的连接在锁芯32外侧上下端的上卡臂和下卡臂，所述上卡臂和下卡臂的内侧形状与所述卡块24的形状相适配，当上下卡臂随锁壳31的挤压收拢时，将所述卡块抱住并带动过滤框架21沿滑槽12进入机壳1内。具体实施时，所述卡口324的结构包含但不限于上述上下卡臂的形式，只要是能在锁壳31压力下闭合锁紧卡块24，无压力下张开释放卡块24的结构均在本申请的保 护范围之内。
所述锁壳31底部上还设置有导向柱311，所述锁芯32上对应导向柱311的位置还开设有导向孔，所述复位弹簧323套设在所述导向柱311的外部。所述导向孔和导向柱311的设置使得复位弹簧323在弹出时保持水平方向，以保持所述锁芯32在部分退出锁壳31时，受力均衡，避免与锁壳31内壁碰撞。
具体实施时，所述过滤网组件2可以通过开设在所述机壳1上的滑槽12进行安装和抽取，也可以通过滑杆或其他方式进行安装和抽取，为了过滤网组件2和机壳1的装配更为精准，所述过滤网组件2的相对的两侧边框可移动的配合在所述滑槽12内，为了便于过滤网组件2顺利的自滑槽12中取出，所述过滤网组件2的边框上还抵压有驱动弹簧25，所述驱动弹簧25一端固定连接在对应所述过滤网组件2的边框的机壳1上，所述驱动弹簧25的驱动方向和过滤网组件2的释放方向保持一致。所述驱动弹簧25的设置使得过在自锁开关3打开后，过滤网组件2可自动弹出，用户可直观的看到过滤网的脏污情况，并判断是否要进行过滤网的清洗。
为了减少过滤网组件2在弹出时受到的摩擦力，所述过滤网组件2的相对的两侧边框分别设置有与过滤网组件2相平行的卡扣结构26，所述卡扣结构26上可转动的套设有滚轮22，所述滚轮22对应设置在滑槽12内，且沿滑槽12长度方向滚动。所述滚轮22与卡扣结构26的设置，减小了过滤网组件2在弹出时受到的摩擦力，提高了用户的使用体验，同时所述滚轮22与卡扣结构26装配效率更好，降低了生产成本。
所述过滤框架21上覆盖有过滤网，述过滤网组件2的外侧边框上还连接有挡板23，所述机壳1上开设有抽拉口13，所述挡板23覆盖在抽拉口13上。 闭合后的挡板23与机壳1外侧齐平，具有简洁美观的外观，同时通过按压所述挡板23可直接将过滤网组件2弹出，提高了过滤网组件2的安装和抽取的效率。为了进一步方便用户的操作，所述挡板23的下方还设置有“PUSAH”的标识层，以便于用户得到更为直观的操作指示。
具体实施时，当所述过滤网组件2装配到位时，卡块24位于卡口324内且被卡口324抱紧，实现自锁功能。当过滤网组件2需要清洁时，轻按过滤网组件2或其外侧连接的挡板23，自锁开关3内的弹性挂钩331脱离锁芯32，锁芯32在复位弹簧323的作用下移位，实现锁芯32的卡口324脱离锁壳31，同时过滤网组件2的卡块24随着卡口324的张开而脱离卡口324。
实施例2
与实施例1不同的是，所述自锁组件包括可转动的连接在锁壳31上的限位挂钩，所述限位挂钩为呈L型的挂钩，所述锁芯上设置有与限位挂钩相配合的卡位，所述限位挂钩的一侧设置有通过磁力将限位挂钩沿反向转动脱离卡位的电磁铁。所述电磁铁通过按压开关控制，按压按压开关时电磁铁所在的电路接通，限位挂钩在电磁铁的磁力作用下抬起时，其脱离卡位，过滤网组件在复位弹簧作用下弹出抽拉口，当过滤网组件安装在抽拉口上时，再次按压按压开关时电磁铁所在的电路断开，电磁铁和限位挂钩之间没有磁力作用。
所述卡位可以是环状、半圆柱或勾状，且当限位挂钩落下时其与卡位相卡合，当限位挂钩在电磁铁的磁力作用下抬起时，其脱离卡位，所述按压开关设置在机壳上。
所述按压开关和由限位挂钩、卡位和电磁铁构成的自锁组件的结构，使得当过滤网组件2正常工作时，即使挡板23被外力意外触发，依然不能打开过 滤网组件，保护了空调运行时的过滤网组件2的正常工作。
实施例3
本发明还提供了一种空调，包括机壳，所述机壳上设置有进风口，所述进风口上覆盖有过滤网装置。
综上所述，所述自锁开关的设置，使得过滤网组件装配到位时，卡块位于卡口的限位处，实现自锁功能。当过滤网组件需要清洁时，仅通过按压过滤网组件外侧或挡板即可该并可以自动弹出过滤网组件，无需打开面板，操作方便。整体式过滤网组件替换原有的左右两件内置式过滤网，清洁一步到位，简化了抽取和安装步骤；用户可以直观的查看到过滤网的脏污情况，并判断是否要进行清洁。过滤网组件两侧设置的滚轮装配，将过滤网推出动作转换为滑动摩擦，提高滚轮的装配效率，减少弹出时的摩擦阻力。
以上结合具体实施例描述了本发明的技术原理。这些描述只是为了解释本发明的原理，而不能以任何方式解释为对本发明保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本发明的其它具体实施方式，这些方式都将落入本发明的保护范围之内。
