背景技术
现在市场上各种厂家的洗衣机琳琅满目，功能也越来越多，随着人工智能的发展，对洗涤剂投放的操作便利性和可靠性提出了越来越高的要求，在操作便利性方面，虽然市场上已出现了一次性存放多量洗衣液用于多个洗涤周期的智能投放洗衣机，在某种程度上减少了使用者的操作步骤，但是，用户仍需亲自去市场上购买袋装、瓶装等包装方式不统一的洗衣液，不规律性地向洗衣机固有部件—洗涤剂存放槽中投放适量洗涤剂，换而言之，一瓶或一包洗衣液仍需通过多次投放。洗涤剂的投放可靠性取决于盛放洗涤剂的装置，虽然市场上已经出现了各种用于盛放洗涤剂的装置，但是对盛放洗涤剂的装置的固定方式都过于复杂。
申请号为CN201310573169.1的中国专利公开了一种用于洗衣机的洗涤剂盒设备，包括：洗涤剂盒，被设置为打开和关闭，以及具有悬挂部；按钮，在洗衣机本体中或上；以及盒固定装置，用于通过按钮的操作来限制洗涤剂盒的移动，该洗涤剂盒设备体积较小，无法容纳较多洗涤剂，洗涤剂盒设备安装和取出结构复杂，制造成本高，洗涤剂盒设备的清洗不方便，在更换洗涤液时容易造成不同品牌的液体混合，导致洗出来的衣服带有不同品牌洗涤液的气味，若洗衣机长时间不使用，洗涤剂盒中的液体会干涸，造成洗涤液管路堵塞。
申请号为CN201310737619.6的中国专利公开了一种内藏洗涤剂盒的洗衣机，包括洗衣机箱体、设置在箱体上的控制盘座及安装在控制盘座上的上盖，所述的控制盘座内设置有至少一个用于投放固体洗涤剂的腔室和至少一个用于盛放液体洗涤剂的容器，所述的腔室和容器均具有设置在所述控制盘座的上端面上的洗涤剂投放口，所述上盖在闭合状态遮盖所述洗涤剂投放口；所述的控制盘座内还设有与腔室和容器均连通的洗涤剂自动投放装置，该洗涤剂自动投放装置为利用进水水流通过文丘里管时产生的负压抽取容器内液体洗涤剂并定量投放的装置。但是上述结构还存在如下缺陷：1、控制盘座下部空间不足，该洗衣机将洗涤剂容器设置于控制盘座内，占用了较大的下部空间，而随着技术的进步，现有洗衣机的功能越来越多，对应需要安装加多的电器元件，控制盘座下部的空间不足多功能电子模块的安装；2、需要用户投放洗涤剂，导致洗涤剂投放过量，从洗涤剂投放口溢出；3、洗涤剂投放口长时间容 易积灰变脏，不易清洗。
有鉴于此特提出本发明。
