作为一种可选实施方式，洗涤剂储存仓100或连接件300内设置有第二检测装置，优选的，设置在连接件300的连接主管310中，第二检测装置用于检测洗涤剂储存仓100或连接件300内的洗涤剂高度，当洗涤剂储存仓100或连接件300中的洗涤剂低于预设高度时，第二检测装置能够传递信号至洗衣机的控制装置，控制装置进行报警， 提醒添加洗涤剂。
本公开还提供一种洗衣机，洗衣机包括如上的洗涤剂投放装置、内筒以及控制装置，洗涤剂投放装置的洗涤剂出口连通内筒，洗涤剂投放装置与控制装置信号连接。
进一步的，上述洗衣机中的洗涤剂投放装置的工作原理如下：
洗涤剂储存仓100中添加洗涤剂，启动洗衣机，洗涤剂投放装置启动，出料开关关闭，进料开关打开，洗涤剂储存仓100中的洗涤剂通过连接件300进入洗涤剂定量仓200中，当洗涤剂定量仓200的第一检测装置检测到对应的洗涤剂定量仓200中的洗涤剂达到预设量时，关闭对应的进料开关。
当洗衣机运行洗衣程序时，对待洗涤衣物进行称重，根据待洗涤衣物的重量选择需要添加的洗涤剂量，并打开对应数量的洗涤剂定量仓200的出料口投放洗涤剂；当洗涤剂定量仓200中的洗涤剂被投放后，对应的出料开关关闭，对应的进料开关打开，洗涤剂储存仓100中的洗涤剂加入洗涤剂定量仓200中，当洗涤剂定量仓200的第一检测装置检测到对应的洗涤剂定量仓200中的洗涤剂达到预设量时，关闭对应的进料开关，洗涤剂定量仓200添加洗涤剂完毕，以供再次使用。
以第二检测装置设置在连接件300的连接主管310为例，当第二检测装置检测到连接主管310中的洗涤剂低于预设高度时，第二检测装置发送信号至洗衣机的控制装置，控制装置进行报警，提醒添加洗涤剂。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。相反，当元件被称作“直接在”另一元件“上”时，不存在中间元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
在本公开描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。
同时，本说明书中所引用的如“上”、“下”、“左”、“右”、“中间”及“一”等的用语，亦仅为便于叙述的明了，而非用以限定本公开可实施的范围，其相对关系的改变或调整，在无实质变更技术内容下，当亦视为本公开可实施的范畴。
以上所述实施例仅表达了本公开的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本公开专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本公开构思的前提下，还可以做出若干变形和改进，这些都属于本公开的保护范围。因此，本公开专利的保护范围应以所附权利要求为准。
