Description

一种添加剂投放装置及洗衣机 技术领域
本发明涉及家用电器领域的一种洗衣机，尤其涉及一种应用洗衣机的、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，如之前的一篇中国专利中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。
还有另一篇中国专利申请文件中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。
但是，现有的添加剂自动投放装置在使用之后，会因添加剂在装置内部管路中残留而造成堵塞、影响添加剂投放装置下次使用的问题；同时，现有的添加剂自动投放装置，普遍存在结构复杂、控制结构过多等问题，使得自动投放装置的成本过大、无法实现普及。
此外，如何保证抽出的添加剂不随水流向水路出水口流出，实现在水路中暂存的效果，需要对水路进行合理改进。
有鉴于此，特提出本发明。

本发明与现有技术相比的有益效果如下：
通过上述设置，使得自动投放装置可经抽吸结构实现向供水管路中抽吸添加剂，并使抽出的添加剂受供水管路内设置的升高凸变的阻挡作用而逆流流向供水管路上游流动，实现了添加剂在供水管路中暂时留存的效果。
同时，通过在供水管路的抽吸结构连接处的上下游分别设置升高凸变，以使抽出的添加剂受升高凸变引导而流向上游的存液腔内，实现对添加剂进行逆流存放，达到添加剂自存液腔同一开口流出和流入的效果。
另外，通过在添加剂投放装置上设置经对冲机构相连的多个供水管路和出水支路，丰富了自动投放装置的水流形式，达到了自动投放装置在洗衣机不同洗涤程序时分别提供相应进水水流的使用效果。

具体实施方式
本发明实施例中介绍了一种添加剂自动投放装置，所述自动投放装置应用于现有的洗衣机，用于向洗衣机盛水筒内投放添加剂；本发明实施例中所述的添加剂可以为洗涤剂、柔顺剂、添香剂、漂白剂、消毒剂等现有对衣物进行处理的液态添加物中任一或组合。
如图1至图9所示，本发明实施例中介绍了一种添加剂自动投放装置，其包括，供水管路1，用于供洗衣机进水水流流动、使进水水流流入洗衣机盛水筒中；储液盒2，其内容纳有添加剂；抽吸结构，其包括提供抽吸动力的动力单元，能够通过动力单元提供抽吸动力，将储液盒2内的添加剂抽吸至供水管路1、并在供水管路中流经进水水流与抽出的添加剂冲相混合后再冲出，同时部分进水水流经抽吸结构流入供水管路、以对抽吸结构进行冲洗。
本发明实施例中，抽吸结构通过对构成管路连接方式进行合理设计，使其仅安装两个单向逆止阀，就可通过动力单元的停开机、进水水流停开的相互配合，实现对内部管路连接方式进行调整，达到向供水管路1中抽吸添加剂、对添加剂投放并对抽吸结构冲洗进行切换使用的效果。
本发明实施例中，所述的自动投放装置，包括至少两个储液盒2，各储液盒2中可以分别存储不同类别的添加剂，各储液盒2经控制装置择一、或组合的经抽吸结构与供水管路1相连，以向供水管路1中流入相应储液盒2中的对应添加剂。
实施例一
如图1所示，本实施例中介绍了一种添加剂投放装置，其包括，供水管路1，供水管路1进水端与洗衣机的进水结构相连通，以将导入洗衣机内部的水流引入投放装置；储液盒2，其内容纳有对衣物进行处理时使用的添加剂；抽吸结构，包括与供水管路至少部分相并联的连接管路，连接管路上设有提供抽吸动力的泵，储液盒与连接管路相连，供水管路和/或连接管路上设有控制管路内液体流向、和/或通断的控制装置，将储液盒2内的添加剂抽吸至供水管路1，或向供水管路1中进水使抽吸的添加剂与进水水流混合后进行投放、并使部分进水流经连接管路对动力单元进行冲洗。
本实施例中，抽吸结构包括提供抽吸动力的泵6，泵6串连接入连接管路，与泵6的进口端相对的连接管路端部为进水端，与泵6的出口端相对的连接管路端部为出口端，连接管路的进水端和出水端均与供水管路1相连通，连接管路的进水端相较连接管路的出水端处于供水管路的上游。
本实施例中，储液盒经抽液管路与连接管路相连，抽液管路与连接管路相连处处于泵进口端与连接管路进水端之间，使储液盒经抽液管路与泵进口端上游的连接管路相连。
通过在供水管路1和/或连接管路7上设置控制装置，以对供水管路1和/或连接管路7进行相应通断切换，令泵的进口端经抽液管路8与储液盒2相连通、将添加剂抽入供水管路中；或向供水管路进水，部分进水经供水管路对抽出的添加剂进行混合并冲至供水管路出水端、另一部分进水经连接管路对泵进行冲洗后再合并流向供水管路出水端而实现对泵进行冲洗清洁的目的。
本实施例中，泵6可以为现有技术中任一可提供抽吸动力的泵结构，例如：电磁泵、抽吸泵、动力泵等等。
本实施例中，供水管路上设有控制供水水流通断的进水阀，进水阀设于抽吸结构与供水管路相连通处的上游；优选的，进水阀设于与连接管路进口端相连处上游的供水管路上；优选的，进水阀16设于供水管路1的进水端。从而，实现了对供水管路1进水水流可控开闭操控，使供水管路1进水水流通断与泵6启闭相配合、提升洗涤剂投放效 率的目的。
本实施例中，在泵工作时、进水阀闭合，以在将储液盒中的添加剂抽入供水管路时，供水管路停止进水，避免泵自连接管路将流入供水管路上游的进水抽入、防止出现添加剂无法抽出情况的发生；同时，在进水阀打开时、泵停止工作，使得流入的进水水流部分流经连接管路，对停止工作、处于连通管段的泵进行冲洗，以实现放置添加剂在泵和连接管路内残留现象的发生。
本实施例中，为了实现抽液管路8和连接管路7通断的切换，控制装置的设置可以采用现有技术中的任一方式，例如：在供水管路1和连接管路7上分别设置控制管路通断的控制阀、泵6的进口端经换向阀择一的与供水管路1和抽液管路8相连通等等。
本实施例中为了降低投放装置的成本，对供水管路1和/或连接管路8上的控制装置进行如下设置：
本实施例中，供水管路1上设有第一单向逆止阀4，第一单向逆止阀4处于连接管路7进口端和连接管路7出口端之间；抽液管路8上设有控制管路内液体仅能自储液盒2向泵6进口端流动的第二单向逆止阀5。
从而，在泵6工作时、供水管路1的进水阀断开停止流入进水，泵6的进口端形成抽吸作用力，储液盒2中的添加剂经抽液管路8抽入、送入供水管路1中，并在供水管路上设置的第一单向逆止阀4的作用下而无法向流连接管路进水端，避免了抽吸至供水管路中的添加剂向连接管路回流情况的发生。同时，在泵6不工作时、供水管路1的进水阀打开开始流入进水，泵6形成供水流自由流经的连通管路，部分进水直接流入供水管路1、部分进水沿泵、连接管路8流动后汇流至供水管路1下游，实现了对泵6进行冲洗的效果，而且在此过程中由于第二单向逆止阀5的作用使抽液管路8断开避免水流流入储液盒2中。
本实施例中，为了保证添加剂抽入供水管路1中不会回流进行了如下设置：供水管路1上设有将泵6抽入供水管路1中的添加剂进行暂存的存液腔3。存液腔3串连接入供水管路1，存液腔1处于连接管路进水端和连接管路出水端之间；优选的，泵6出口端直接、或经连接管路8的出水端与存液腔3相连通。进一步优选的，泵6的出口端与存液腔3上部相连通，使得抽入存液腔3中的添加剂自腔室上部流入、以避免倒流；供水管路1在存液腔3侧壁底部穿过并连通，使得供水管路1提供的水流可对存液腔3底部进行冲刷，令抽入腔室中的添加剂可全部被供水管路1的进水水流冲至供水管路1出水端。进一步优选的，为了保证整个装置的运行平稳性，将存液腔3设置为密封腔室。
本实施例中，添加剂投放装置的具体投放工作过程如下：
首先，闭合供水管路1的进水阀、启动泵6，此时，泵6的进口端形成抽吸力，储液盒2中的添加剂沿抽液管路8抽至泵6、再经连接管路7流入供水管路1上设置的存液腔3中，而在此过程中供水管路1在第一单向逆止阀4的作用下无法将抽至供水管路1中的添加剂流向连接管路7的进水端、防止出现添加剂在连接管路和供水管路之间循环流动情况的发生；
然后，打开供水管路1的进水阀、闭合泵6，此时，泵6形成供水流自由流经的连通管路，供水管路1中的部分进水水流流入存液腔3，将存液腔3中的添加剂直接冲入供水管路1下游；另一部分进水水流沿泵6和连接管路7后再汇流至供水管路1下游，在此过程中经连接管路7的进水水流对泵6进行冲洗，而在第二单向逆止阀5的作用下流经连接管路7的进水水流无法经抽液管路8流入储液盒2中。
通过上述方式，实现了对添加剂进行抽吸投放和对抽吸装置的泵进行冲洗清洁的目的，进而在降低生产成本的前提下实现了对添加剂进行自动投放的效果；同时，由于本申请中的上述添加剂投放装置在运行过程中，采用添加剂投放后及时冲洗的技术方案，避免了添加剂在投放装置内部留存、尤其是防止了添加剂投放装置的动力部件中残留添 加剂而造成腐蚀损坏情况的发生。
如图1所示，本实施例中介绍了一种添加剂投放装置，包括相并联的第一供水管路11和第二供水管路12，第一供水管路11上设有将储液盒2内添加剂抽吸至管路中的抽吸结构，所述的抽吸结构可以将储液盒2中添加剂抽送至供水管路1中的结构。
本实施例中，还可以在第二供水管路上连接抽吸结构，所述抽吸结构可以为单独设置的、也可以为与第一供水管路共用的，进而实现利用第二供水管路进行添加剂自动投放的功能。
本实施例中，第一供水管路11和第二供水管路12经对冲机构10可换向的与多个出水支路中的任一相连通，各出水支路分别与洗衣机盛水筒的不同进水结构相连，以将洗衣机进水输送至任一盛水筒的进水装置，进而实现对不同进水结构供水的目的。上述盛水筒的进水装置可以为现有的任一结构，例如：向盛水筒内喷淋进水的喷淋结构、向盛水筒内流入洗涤剂剂和/或洗衣粉的主洗进水腔、向盛水筒内流入柔顺剂等辅助添加剂的辅洗进水腔等等。
本实施例中，为了实现上述效果进行如下设置：第一供水管路11和第二供水管路12的出水端相交错一倾斜角的设于对冲机构10的同一侧，第一出水支路13、第二出水支路14、第三出水支路15的进水端处于对冲机构10的另一侧。通过在添加剂投放装置上设置经对冲机构相连的多个供水管路和出水支路，丰富了自动投放装置的水流形式，达到了自动投放装置在洗衣机不同洗涤程序时分别提供相应进水水流的使用效果。
本实施例中，第一供水管路11出水端与第一出水支路13进水端同轴相对、间隔设置，第一供水管路11单独供水时，供水水流自第一供水管路11出水端喷出并流入第一出水支路13进水端；第二供水管路12出水端与第二出水支路14进水端同轴相对、间隔设置，第二供水管路12单独供水时，供水水流自第二供水管路12出水端喷出并流入第二出水支路14进水端；第三出水支路15进水端处于第一出水支路13进水端和第二出水支路14进水端之间，第一供水管路1和第二供水管路1同时供水时两股水流相互干涉合并为同一股供水水流、供水水流流入第三出水支路15进水端。优选的，为了保证汇聚后的水流准确流入第三出水支路，将第三出水支路进水端的轴线沿第一出水支路进水端和第二出水支路进水端的中分线设置。
本实施例中还介绍了一种洗衣机，其特征在于：安装有上述的添加剂投放装置，添加剂投放装置的供水管路1与洗衣机盛水筒相连，以将抽吸结构自储液盒2抽出的添加剂输送至盛水筒中。

本实施例中，为了实现对抽吸添加剂完成后、停止工作的泵6进行冲洗，将连接管路7与第一供水管段26相连通，以将流入的部分进水流经连接管路而对泵6进行冲洗后再汇流入供水管路1下游。同时，为了防止泵将供水管路1中的液体抽入连接管路7中，在供水管路1上设置第一单向逆止阀4，第一单向逆止阀4处于第一供水管段26与进水口24相连通端。
本实施例中，存液腔3具有第二开口22，第二开口22经第一供水管段26与投放装置的进水口24相连通，用于将供水管路1中的进水引入存液腔3内，使暂存添加剂与进水水流预先混合形成添加剂与水混合物，并随着流入进水水流的增多而自第一开口21冲入第二供水管段27、再经对冲机构10进行投放；优选的，连接管路7与第一供水管段26相连通，第一供水管段26上设有第一单向逆止阀4，控制管路内液体仅能自向存液腔3方向流动。
本实施例中，存液腔3设于水盒100内部，靠近水盒100后侧壁设置，以使得存液腔3不会对向外抽拉的储液盒2产生干涉影响；同时，通过将存液腔3设置于水盒100后部，令设于上盖200凸出部23的水路部分与存液腔3之间不会距离过远，保证了水流的顺畅性。
实施例四
如图2中图9所示，本实施例中介绍了一种添加剂投放装置，其包括，容纳添加剂的储液盒2，用于进水的水路300；水路300包括与对冲机构10相连的第一供水管路11和第二供水管路12，用于分别或同时进水形成多路进水水流；第一供水管路11经抽吸结构与储液盒2相连，第一供水管路11上设有存液腔3，抽吸结构用于将储液盒2内的添加剂抽入存液腔3内、再随第一供水管路11进水冲至对冲机构10而进行相应投放。
通过对添加剂投放装置进行如上设置，使得具有添加剂投放功能的供水管路构成了对冲机构的一路进水水流，使得添加剂投放装置可利用对冲机构对液态添加剂进行对应投放；同时，由于供水管路上设有对抽出添加剂进行预存放的存液腔，实现了对添加剂进行预混合后再经对冲机构投放的目的，进而使得供水管路流出的投放液体密度降低、适用于进行对冲流出。
本实施例中，水路300设置于水盒上盖200内部，水盒上盖200具有凸出于水盒100后侧的凸出部23，水路300的至少部分设于凸出部23处，设于凸出部23的水路300至少包括第一供水管路11和第二供水管路12。
本实施例中，对冲机构10包括出水端相交错一倾斜角的设于同一侧的第一进水支路28和第二进水支路29，进水端处于相对另一侧的第一出水支路13、第二出水支路14和第三出水支路15。供水管路1的第二供水管段27与第一进水支路28进水端相连通，第一进水支路28出水端与第一出水支路13进水端同轴相对、间隔设置，供水管路1单独供水时，供水水流自第一进水支路28出水端喷出并流入第一出水支路13进水端。第二供水管路12与第二进水支路29进水端相连通，第二进水支路29出水端与第二出水支路14进水端同轴相对、间隔设置，第二供水管路12单独供水时，供水水流自第二进水支路29出水端喷出并流入第二出水支路14进水端。第三出水支路15进水端处于第一出水支路13进水端和第二出水支路14进水端之间，供水管路1和第二供水管路12同时供水时两股水流相互干涉合并为同一股供水水流、供水水流流入第三出水支路15进水端。
本实施例中，对冲机构10设于水盒后部上方，对冲机构10的进水支路出水端侧下方的水路设有豁口19，豁口19将水路与水盒内部相连通，以将对冲机构处溅射的液体自豁口流入水盒内、避免对冲机构处出现残水而对对冲造成干涉情况的发生。优选的，对冲机构的进水支路出水端侧与出水支路进水端侧之间间隙下方的水路内壁为向豁口方向逐渐下降的斜面20。
本实施例中，第一出水支路13的出水端设有与水盒100内主洗腔相连通的洗涤投放口，第二出水支路14的出水端与水盒100上设置的、和外部相连通的喷淋口相连通，第三出水支路15的出水端与水盒100内柔顺剂腔相连通的柔顺剂投放口。
实施例五
如图2中图9所示，本实施例中介绍了一种添加剂投放装置，其包括供水管路1，供水管路1设有沿进水水流方向调高水路高度的升高凸变，升高凸变上游的供水管路1经抽吸结构与储液盒2相连，用于将抽入供水管路1的添加剂在升高凸变的阻挡作用下逆流流向供水管路1上游。
本实施例中，供水管路1上串连有存液腔3，存液腔3处于与抽吸结构相连处上游的供水管路1上，以使得在升高凸变作用下逆流流动的添加剂进入存液腔3内暂存。
本实施例中，供水管路1包括第一供水管段26和第二供水管段27，第一供水管段26将存液腔3与添加剂投放装置的进水口24相连通，第二供水管段27将存液腔3与对冲机构10相连，以使得流入的进水水流经存液腔3后流向对冲机构10。
本实施例中，抽吸结构与第二供水管段27相连，以将抽出的添加剂送入第二供水管段27内。第二供水管段27中设有处于抽吸结构相连处上游的第一升高凸变31、处于 下游的第二升高凸变32，以使得第二供水管段27形成自存液腔3至对冲机构10方向逐渐上升的三部分，抽液结构与中间高度部分相连，使抽入供水管路内的添加剂受重力作用、因第一升高凸变阻挡而流入存液腔。
本实施例中，抽液结构与第二供水管段27中部相连，连接处的上游和下游分别设置至少一升高凸变，连接处上游的第一升高凸31变使上游管路低于连接处、连接处下游的第二升高凸32变使下游管路高于连接处，以使抽入供水管路1中的添加剂受第二升高凸变32阻挡而无法流出、并受第一升高凸变31引导而逆流流向存液腔3。
本实施例中，第二供水管段27具有两条相平行延伸的直线延伸部，两直线延伸部的同一侧端部经弯折部相连，另一侧端部分别与存液腔3的第一开口21和对冲机构10的第一进水支路28相连。通过将第二供水管段进行上述设置，使得第二供水管路在尽量缩减占用空间的前提下具有更长的衍生长度，进而提升存液腔的存储容积。
本实施例中，抽吸结构包括：与供水管路1相并联的连接管路7，连接管路7的一端经三通18与投放装置的进水口24和第一供水管段26的进水端分别相连，另一端与泵6的泵进口33相连、泵6的泵出口34与供水管路1的第二供水管段27中部相连；连接管路7的中部经抽液管路8与储液盒2相连。通过上述设置，使得存液腔与第二供水管段相连的开口同时构成供抽入供水管路中添加剂流入、和供存液腔内添加剂与进水混合液流出的双重功能。
本实施例中，泵出口34与第二供水管段27相连处具有向第二供水管段27内部凸出升高的凸台30，对冲机构10的第一进水支路28进水端的高度高于凸台30的高度，以利用凸台30与第二供水管段27之间的高度差形成泵出口34与第二供水管段27相连处上游的第一升高凸变31、凸台30与第二进水支路28进水端之间的高度差形成泵出口34与第二供水管段27相连处下游的第二升高凸变32。
本实施例中，为了进一步实现抽入供水管路1中添加剂向存液腔3内的回流，可以将第二供水管段27设置为自存储腔3向对冲机构10逐渐升高的方向倾斜延伸。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
