Description

一种洗衣机进水控制方法及洗衣机 技术领域
本发明属于洗衣机技术领域，具体涉及一种洗衣机进水控制方法及洗衣机。
背景技术
滚筒洗衣机通过滚筒的转动来清洗衣服，在洗衣结束后，滚筒内和观察视窗上会残留有清洗过程中产生的泡沫等物质，为了在洗衣结束后清洗滚筒内部以及观察视窗等部位，通常会设置喷淋系统对上述部位进行清洗。
具有喷淋和洗涤添加剂(例如消毒剂、芳香剂等)功能的洗衣机一般需要通过两个电磁阀控制进水，这种设置不仅使洗衣机内部的构件增多而且采用两个电磁阀控制在进水时不易控制、容易紊乱，需要复杂的控制程序设置增加，生产制造成本。另外，电磁阀越多，洗衣机出现故障的几率就高，不利于洗衣机整体的稳定性能。
滚筒洗衣机的喷淋系统通常位于滚筒的顶部，包括进水阀、电磁阀、喷淋管和喷淋装置；进水阀与水龙头连接，水龙头提供洗衣用水；进水阀连接电磁阀、电磁阀与喷淋管的入水口连接，喷淋管的出水端连接喷淋装置，喷淋装置的多个喷淋头设置在滚筒内侧壁和观察视窗旁侧。在洗衣结束后，电磁阀开启，水通过喷淋管流到喷流装置中，水通过喷淋装置上的多个喷流头喷洒出，喷洒出的水柱能够冲洗滚筒内部和观察视窗。冲洗结束后，滚筒洗衣机关闭电磁阀结束洗衣程序，电磁阀关闭后，使得滚筒洗衣机内部形成一个封闭空间，造成喷淋系统的喷淋管路呈密封状态，会使喷淋管内残留有水无法流出；在用户下一次需要洗衣服而打开滚筒洗衣机门体时，残留水会从喷淋管中喷出流到地板上，使用体验不佳。
鉴于现有技术洗衣机存在的上述技术缺陷，特提出本申请。
发明内容
本发明的目的在于克服现有技术存在的缺陷的至少一个，提供一种洗衣机进水控制方法及洗衣机。
本发明所述的洗衣机通过一个单进水阀同时实现对洗涤添加剂投放和洗衣机的喷淋观察窗玻璃门和/或玻璃密封窗垫功能，设置精简、简洁度高，可以有效降低洗衣机的故障率。并且所述洗衣机还可以避免洗涤添加剂的进水管路的水残留，防止开启观察窗时滴水的问题。
为了解决所述的技术问题，达到所述的技术效果，本发明采用的技术方案的基本设计思路为：
一种洗衣机，包括投放装置、单进水阀，自同一单进水阀的出水口向投放装置的内部分支出多条管路，包括用于洗涤剂和/或添加剂投放的第一管路、用于喷淋观察窗玻璃门和/或玻璃密封窗垫的第二管路，并且第一管路与第二管路的出水量比例为1：N，N≥1，令洗衣机进水时第一管路与第二管路同时出水。
现有技术中，具有喷淋和洗涤添加剂功能的洗衣机需要通过至少两个电磁阀控制进水，增加洗衣机内部的构件，而且采用多个电磁阀控制进水时程序复杂、容易紊乱，而且生产制造成本高。另外，电磁阀的增加还会提高洗衣机出现故障的几率，不利于洗衣机整体性能的稳定，给用户使用带来不便。
而本发明所述的洗衣机，仅仅使用一个单进水阀和控制管路的出水比例就可以简单地同时实现洗涤添加剂的投放和喷淋功能，设计精简度高，降低生产制造成本和洗衣机的故障率，提高洗衣机的整体稳定性，有利于减少维修频次、给客户带来更好的使用体验。
尤其，所述的设置可以使投放洗涤添加剂的管路在不需要进水时与大气保持相通，便于快速地将其进水管路中残留的水排出，避免水渍残留孳生微生物而破坏洗衣机的卫生状况。
因此，本发明所述的技术方案利用一个单进水阀和对管路的进水比例的控制不仅实现了进水时的洗涤剂和/或洗涤添加剂的投放与喷淋的双功能，而且在洗衣机不进水时还可以将管路中残留的水迅速排空，解决了玻璃观察窗打开时滴水的问题。
优选地，单进水阀设于投放装置的内部，或者设于投放装置的外部并通过管路与投放装置连接。
优选地，包括设于投放装置内部的添加剂腔室，嵌设于投放装置内部的进水管路；进水管路的一端与单进水阀的出水口连通、另一端分出第一和第二管路，第一管路与添加剂腔室连通。
上述的设置中进水管路嵌设于投放装置内部可以有效地减少额外的安装固定部件，借助投放装置自身结构将进水管路固定的效果更好，避免进水管路错落复杂地盘绕于洗衣机内部，使洗衣机的结构更加整洁、美观并且精简内部空间的设置，降低故障率。
优选地，第一管路的出水口与大气相通且其出水能进入添加剂腔室内部。
更优选地，第一管路具有多个小孔并环绕设置在添加剂腔室的周围，小孔的出水冲刷添 加剂腔室的侧壁。
第一管路的出水口按照上述设置可以便于将洗涤添加剂充分稀释溶解，使洗涤添加剂的投放更加均匀，避免局部投放不均，造成洗涤添加剂在衣物上残留。在洗衣机进水关闭后，管路中的水能够被迅速排空，防止观察窗打开时窗垫滴水。
优选地，第二管路自投放装置的内部延伸至外部并且其出水口朝向洗衣机的玻璃窗门和/或玻璃密封窗垫。
第二管路的上述设置方案可以确保洗衣机的玻璃窗门和或玻璃密封窗垫的清洁卫生，避免洗涤剂或其他污渍在其上造成残留，借助洗衣过程的进水实现清洁，不需要用户自行进行清洁，提高用户使用感受，并且一水多用，有利于节省水资源。
优选地，第一管路与进水管路在同一水平方向上设置并连接一体，第二管路与进水管路连通，第二管路的出水口所在的位置低于第一管路的出水口。
上述设置可以使进水由进水管顺畅地分成两路，确保洗涤剂和/或洗涤添加剂和喷淋功能稳定顺畅地同时实现，并且可以在不进水时快速地将管路中的水排空，防止观察窗打开时窗垫滴水的问题。
优选地，第一管路的出水口设有喷洒部，喷洒部具有朝向添加剂腔室内部各个方向的多个出水孔。
设置所述的喷洒部可以确保添加剂腔室内部的添加剂等被充分地稀释并完全投放，避免添加剂在添加剂腔室内部结构中造成残留，使添加剂腔室内部更加洁净，节省洗涤添加剂并且避免孳生微生物。
本发明的另一重要目的在于，提供一种利用如本发明所述的洗衣机实现由同一个单进水阀同时实现洗涤剂和/或添加剂投放以及喷淋观察窗玻璃门和/或玻璃密封窗垫的洗衣机进水控制方法。
为了解决所述的技术问题，达到所述的技术效果，本发明采用的技术方案为：
一种洗衣机进水控制方法，洗衣机包括投放装置、单进水阀，自同一单进水阀的出水口向投放装置的内部分支出多条管路，第一管路与第二管路连通，单进水阀打开、进水时，水流同时进入第一管路、第二管路并同时出水。
优选地，第一管路的出水口与投放装置内部设置的添加剂腔室连通，用于洗涤剂和/或添加剂投放，第二管路用于喷淋观察窗玻璃门和/或玻璃密封窗垫，第一管路与第二管路同时出 水并且两者的出水量比例为1：N，N≥1。
优选地，第一管路与进水管路在同一水平方向上设置并连接一体，第二管路与进水管路连通，第二管路的出水口所在的位置低于第一管路的出水口，单进水阀打开、进水时水流同时由第一管路、第二管路的出水口流出。
优选地，第一管路的出水口位于添加剂腔室开口的上部且与大气相通，当单进水阀关闭、不进水时，进水管路中残留的水分经第二管路排出。
本发明所述的洗衣机进水控制方法程序简单，能够借助精简的洗衣机结构同时实现洗涤添加剂的投放和喷淋功能的实现，不需要设置复杂的洗衣机控制程序，降低洗衣机研发成本。
上述的方法可以提供水资源的利用效率，并且可以确保喷淋观察窗玻璃门和/或玻璃密封窗垫的洁净卫生，防止观察窗打开时窗垫滴水。
优选地，控制洗衣机持续进水；或者，控制洗衣机持续进水M时间段、中断N时间段后再持续进水，以M+N时间段为一个周期进水S个周期,S为自然数且S＞1。
以上方法可以确保洗涤添加剂准确均匀投放，确保喷淋观察窗玻璃门和/或玻璃密封窗垫的洁净卫生。
本发明所述的洗衣机和现有技术的洗衣机相比具有下列有益效果：
1、借助同一单进水阀和进水比例的控制，同时实现洗涤添加剂投放和喷淋功能，提高洗衣机设计的精简度，降低了洗衣机的故障率；
2、洗涤添加剂的进水管路在不需要进水时，可以快速地将管路中残留的水分排空，避免打开观察窗时窗垫滴水的问题，同时有效防止微生物孳生，洁净卫生；
3、在现有洗衣机的大致结构下进行改进即可，降低研发生产成本。

所述的洗衣机进水控制方法不同，本实施例中控制洗衣机持续进水M时间段、中断N时间段后再持续进水，以M+N时间段为一个周期进水S个周期,S为自然数且S＞1。
本实施例的洗衣机的单进水阀1设于投放装置3的外部并通过管路与投放装置3连接。
所述洗衣机的投放装置3内部设有添加剂腔室4，并且投放装置内部3的嵌设有进水管路2；
进水管路2的一端与单进水阀1的出水口连通、另一端分出第一和第二管路21、22，第一管路21与添加剂腔室4连通。
第一管路21的出水口与大气相通且其出水能进入添加剂腔室4内部，作为优选地，第一管路21具有多个小孔并环绕设置在添加剂腔室4的周围，小孔出水冲刷添加剂腔室4的侧壁，第二管路22自投放装置3的内部延伸至外部并且其出水口朝向洗衣机的玻璃窗门和/或玻璃密封窗垫。
第一管路21与进水管路2在同一水平方向上设置并连接一体，第二管路22与进水管路2连通，第二管路22的出水口所在的位置低于第一管路21的出水口。
优选地，第一管路21与进水管路2为同一管路，第二管路22与进水管路2连通且沿进水管路2的垂直方向设置。
上述设置可以使进水由进水管顺畅地分成两路，确保洗涤剂和/或洗涤添加剂和喷淋功能稳定顺畅地同时实现，并且可以在不进水时快速地将管路中的水排空，防止观察窗打开时窗垫滴水的问题。
管路嵌设于投放装置内部可以有效地减少额外的安装固定部件，借助投放装置自身结构将管路固定的效果更好，避免管路错落复杂地盘绕于洗衣机内部，使洗衣机的结构更加整洁、美观并且精简内部空间的设置，降低故障率。
或者在其他的实施例，第一管路21的出水口悬空设于添加剂腔室4开口的上部并位于添加剂腔室4的中间部位。
第一管路21的出水口按照上述设置可以便于将洗涤添加剂充分稀释溶解，使洗涤添加剂的投放更加均匀，避免局部投放不均，造成洗涤添加剂在衣物上残留。
第一管路21的出水口设有喷洒部，喷洒部具有朝向添加剂腔室4内部各个方向的多个出水孔。
设置所述的喷洒部可以确保添加剂腔室内部的添加剂等被充分地稀释并完全投放，避免添加剂在添加剂腔室内部结构中造成残留，使添加剂腔室内部更加洁净，节省洗涤添加剂并且避免孳生微生物。
第二管路22自投放装置3的内部延伸至外部并且其出水口朝向洗衣机的玻璃窗门和/或玻璃密封窗垫。
第二管路的上述设置方案可以确保洗衣机的玻璃窗门和或玻璃密封窗垫的清洁卫生，避免洗涤剂或其他污渍在其上造成残留，借助洗衣过程的进水实现清洁，不需要用户自行进行清洁，提高用户使用感受，并且一水多用，有利于节省水资源。
所述的洗衣机，仅仅使用一个单进水阀和控制管路的出水比例就可以简单地同时实现洗涤添加剂的投放和喷淋功能，设计精简度高，降低生产制造成本和洗衣机的故障率，提高洗衣机的整体稳定性，有利于减少维修频次、给客户带来更好的使用体验。
尤其，所述的设置可以使投放洗涤添加剂的管路在不需要进水时与大气保持相通，便于快速地将其进水管路中残留的水排出，防止观察窗打开时窗垫滴水，同时避免水渍残留孳生微生物而破坏洗衣机的卫生状况。
本实施例所述的技术方案利用一个单进水阀和对管路的进水比例的控制不仅实现了进水时的洗涤剂和/或洗涤添加剂的投放与喷淋的双功能，而且在洗衣机不进水时还可以将管路中残留的水迅速排空，解决了玻璃观察窗打开时滴水的问题。
本实施例提供一种利用如本发明所述的洗衣机实现由同一个单进水阀同时实现洗涤剂和/或添加剂投放以及喷淋观察窗玻璃门和/或玻璃密封窗垫的洗衣机进水控制方法。
一种洗衣机进水控制方法，洗衣机包括投放装置3、单进水阀1，自同一单进水阀1的出水口向投放装置3的内部分支出多条管路，第一管路21与第二管路22连通，单进水阀1打开、进水时，水流同时进入第一管路21、第二管路22并同时出水。
第一管路21的出水口与投放装置3内部设置的添加剂腔室4连通，用于洗涤剂和/或添加剂投放，第二管路22用于喷淋观察窗玻璃门和/或玻璃密封窗垫，第一管路21与第二管路 22同时出水并且两者的出水量比例为1：N，N≥1。
第一管路21与进水管路2在同一水平方向上设置并连接一体，第二管路22与进水管路2连通，第二管路22的出水口所在的位置低于第一管路21的出水口，单进水阀1打开、进水时，水流同时由第一管路21、第二管路22的出水口流出。
第一管路21的出水口位于添加剂腔室4开口的上部且与大气相通，当单进水阀1关闭、不进水时，进水管路2中残留的水分经第二管路22排出。
本实施例控制洗衣机持续进水M时间段、中断N时间段后再持续进水，以M+N时间段为一个周期进水S个周期,S为自然数且S＞1。
所述的洗衣机进水控制方法程序简单，能够借助精简的洗衣机结构同时实现洗涤添加剂的投放和喷淋功能的实现，不需要设置复杂的洗衣机控制程序，降低洗衣机研发成本。
上述的方法可以提供水资源的利用效率，并且可以确保喷淋观察窗玻璃门和/或玻璃密封窗垫的洁净卫生，防止观察窗打开时窗垫滴水。
以上方法可以确保洗涤添加剂准确均匀投放，确保喷淋观察窗玻璃门和/或玻璃密封窗垫的洁净卫生。
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。
