Description

一种自动投放装置及控制方法及多滚筒洗衣机 技术领域
本发明涉及家用电器领域的一种滚筒洗衣机,尤其涉及一种具有至少两个盛水筒的多滚筒洗衣机,特别涉及一种应用于上述多滚筒洗衣机的、用于添加衣物处理过程中添加剂的自动投放装置。
背景技术
传统的洗衣机在洗涤过程中使用的添加剂如洗涤剂、柔软剂、消毒液等与洗衣机是分开放置的,在洗衣机上没有设置添加剂的投放装置,添加剂不能自动投放,该结构不能实现洗衣机全自动洗衣控制过程。随着洗衣机自动化的提高,大多洗衣机设置成将放置洗涤剂或/和柔软剂的添加剂盒与进水管路相通,通过进水将添加剂盒内的洗涤剂或/和柔软剂冲入盛水筒中,但是该结构必须每次洗衣都要先将洗涤剂或/和柔软剂放入添加剂盒中,同样没有实现全自动洗衣控制过程。
目前已有大量有关添加剂自动投放装置的专利申请,申请号为97208723.0的中国专利公开了一种洗衣机洗涤剂添加装置,它是在洗衣机箱体上设有与瓶配合的容腔,容腔的底部是圆锥通孔,在通孔上固定有垂直固定片,垂直固定片固定洗涤液导管,瓶体与容腔相配合,在瓶口上设置有圆锥状导入管,在瓶体底部有换气口。该结构无法控制洗涤剂添加量,且容易损坏从而浪费洗涤剂。
申请号为200610136059.9的中国专利公开了一种具有虹吸单元的洗涤剂盒的洗衣机的洗涤剂供应装置,将洗涤剂注入洗涤剂盒,在将洗涤水注入洗涤剂盒将盒内的洗涤剂稀释后从虹吸单元排入洗涤缸。该发明解决了浓洗涤剂直接进入洗涤缸所带的损伤被洗衣物的问题,但是无法实现洗涤剂的自动添加剂精确控制。
同时,随着人们生活水平的提升,为了满足用户衣物处理多样性、高需求的目的,申请人之前提出来一种多滚筒洗衣机,该洗衣机上设有多个相互独立设置的、可分别对衣物进行处理的盛水筒,以实现对用户不同衣物分别处理、满足用户不同衣物多样性、个性化处理的需求。因此,如何设置一种自动投放装置,以利用洗衣机的进水向不同的盛水筒中分别进行相应添加剂的投放就成了急需解决的问题。
有鉴于此,特提出本发明。
