Description

滚筒洗衣机和用于滚筒洗衣机的蒸汽洗控制方法 技术领域
本发明属于洗衣机技术领域，具体提供一种滚筒洗衣机和用于滚筒洗衣机的蒸汽洗控制方法。
背景技术
滚筒洗衣机是能够对衣物进行洗涤、甩干和/或烘干的机器。随着社会的进步，滚筒洗衣机逐渐成为每个家庭必备的家用电器，为人们的生活提供了极大地便利。
随着人们生活水平的不断进步，人们对滚筒洗衣的功能提出了更多的要求。目前很多滚筒洗衣机开始增加蒸汽洗功能，通过向内筒内的衣物供应蒸汽来去除衣物上的褶皱。
滚筒洗衣机在执行蒸汽洗程序时，需要直接向外筒内注水，水进入外筒的底部，然后通过加热装置进行加热产生蒸汽，蒸汽通过内筒上的孔进入筒内，对衣物进行熨烫，从而达到除皱的目的。然而，为了便于直接向外筒内注水，现有的滚筒洗衣机大多在外筒上开设了注水口，通过该注水口向外筒内注水，增加了加工成本。
此外，实现的方式是通过进水，水进入外筒的底部，然后通过加热装置进行加热产生蒸汽，蒸汽通过内筒上的孔进入筒内，对衣物进行熨烫，从而达到除皱的目的。实现蒸汽洗的关键是前期进水时，要避免水进入内筒的内部，以防打湿内筒内的衣物，否则会影响蒸汽洗的除皱效果。然而，现有的蒸汽洗的进水结构比较复杂，成本较高。
因此，本领域需要一种新的技术方案来解决上述问题。
发明内容

在上述用于滚筒洗衣机的蒸汽洗控制方法的优选技术方案中，所述透气孔对准所述内筒的后壁与所述外筒的后壁之间的间隙。
在上述用于滚筒洗衣机的蒸汽洗控制方法的优选技术方案中，所述透气孔对准所述内筒后部未设置孔的部分。
在上述用于滚筒洗衣机的蒸汽洗控制方法的优选技术方案中，所述透气孔内安装有柱形喷水构件，所述柱形喷水构件的进水口与所述供水源连通，在组装好的情形下，所述柱形喷水构件的出水口朝向所述外筒的后壁设置以使从所述出水口喷出的水能够在不经过所述内筒的内部的情形下进入所述外筒的底部。
在上述用于滚筒洗衣机的蒸汽洗控制方法的优选技术方案中，所述滚筒洗衣机还包括定位结构，所述定位结构设置为能够防止所述柱形喷水构件相对于所述透气孔转动。
在上述用于滚筒洗衣机的蒸汽洗控制方法的优选技术方案中，所述定位结构包括设置在所述透气孔的内壁上的第一定位结构以及设置在所述柱形喷水构件的外壁上的第二定位结构，所述第一定位结构与所述第二定位结构相配合能够防止所述柱形喷水构件相对于所述透气孔转动。
在上述用于滚筒洗衣机的蒸汽洗控制方法的优选技术方案中，所述第一定位结构和所述第二定位结构中的一个为条形定位筋，所述第一定位结构和所述第二定位结构中的另一个为条形定位槽，所述条形定位筋与所述条形定位槽相适配。
在上述用于滚筒洗衣机的蒸汽洗控制方法的优选技术方案中，所述柱形喷水构件的外壁上设置有环形挡筋，所述环形挡筋靠近所述进水口设置，所述环形挡筋的外径大于所述透气孔的内径。

在上述用于滚筒洗衣机的蒸汽洗控制方法的优选技术方案中，所述柱形喷水构件采用橡胶材料制成。
本领域技术人员能够理解的是，在本发明的优选技术方案中，滚筒洗衣机在执行蒸汽洗程序时，通过透气孔向外筒内注水，然后将外筒底部的水加热，产生蒸汽以对内筒内的衣物进行蒸汽洗。即，本发明开发了透气孔的第二功能，使得透气孔既能够起到透气的作用，又能够起到注水的作用。并且，与现有技术相比，无需在外筒上单独开设一个注水口来向外筒内注水，从而能够降低加工成本。
进一步地，透气孔对准内筒的后壁与外筒的后壁之间的间隙。即，在内筒的后壁与外筒的后壁之间具有一定的间隙，透气孔正好形成在该间隙对应的外筒的筒壁上，使得从透气孔进入的水通过该间隙能够直接落到外筒的底部。通过这样的设置，滚筒洗衣机在执行蒸汽洗程序时，通过透气孔向外筒内注水时，能够防止水进入到内筒内，从而能够防止将内筒内的衣物打湿，进而能够避免影响对衣物的处理效果。

更进一步地，滚筒洗衣机还包括定位结构，定位结构设置为能够防止柱形喷水构件相对于透气孔转动。即，在组装好后，通过定位结构能够将柱形喷水构件定位至透气孔内，在进水时，防止柱形喷水构件相对于透气孔发生转动，通过这样的设置，能够保证出水口始终朝向外筒的后壁。
再进一步地，第一定位结构和第二定位结构中的一个为条形定位筋，第一定位结构和第二定位结构中的另一个为条形定位槽，条形 定位筋与条形定位槽相适配。即，在组装好的情形下，条形定位筋正好位于条形定位槽内，通过这样的设置，能够防止柱形喷水构件相对于透气孔转动，并且，在组装时，通过条形定位筋和条形定位槽也能够保证柱形喷水构件的出水口朝向外筒的后壁，从而能够提高装配的准确性。
又进一步地，条形定位筋的横截面和条形定位槽的横截面均为正方形。通过这样的设置，使得条形定位筋不易从条形定位槽内脱出，从而提高了定位结构的可靠性。
又进一步地，柱形喷水构件的外壁上设置多个弹性筋，在组装好的情形下，多个弹性筋均弹性地抵靠在透气孔的内壁上。即，在组装好的情形下，弹性筋被挤塞在透气孔的内壁和柱形喷水构件的外壁之间，通过这样的设置，既能够防止柱形喷水构件从透气孔内脱出，又能够防止柱形喷水构件相对于透气孔转动。

实施例一
基于背景技术指出的现有的滚筒洗衣机在外筒上开设了注水口以向外筒内注水，从而增加了加工成本的问题。本发明提供了一种用于滚筒洗衣机的蒸汽洗控制方法，旨在在滚筒洗衣机执行蒸汽洗程序时，通过形成在外筒的筒壁上的透气孔向外筒内注水。
具体地，如图2和图3所示，本发明的滚筒洗衣机包括箱体1，箱体1内设置有衣物处理剂投放装置6、外筒2和内筒3，衣物处理剂投放装置6的投放口与内筒3连通，能够向内筒3投放衣物处理剂和水的混合液，内筒3设置在外筒2的内部，外筒2相对于箱体1固定设置，内筒3能够在驱动装置(图中未示出)的驱动下，相对于外筒2转动，外筒2的前端成开口设置，内筒3由外筒2的前端开口处装入外筒2中，外筒2与内筒3的轴线重合，驱动装置设置在外筒2的后部，外筒2的筒壁上设置有透气孔21，透气孔21与箱体1的外部连通，以便在向内筒3注水时能够将外筒2和内筒3内的气体排出，其中，透气孔21与衣物处理剂投放装置6连通，即，透气孔21通过衣物处理剂投放装置6与 箱体1的外部连通，在通过衣物处理剂投放装置6向内筒3投放衣物处理剂和水的混合液时，内筒3和外筒2中的空气可以通过透气孔21排入衣物处理剂投放装置6内，再经衣物处理剂投放装置6流到箱体1的外部，当然，也可以使透气孔21直接与箱体1的外部连通。
透气孔21还与供水源连通。具体而言，如图2所示，可以在透气孔21的外端(位于外筒2外侧的一端)安装一个三通管5，三通管5的第一支管51与衣物处理剂投放装置6连通，三通管5的第二支管52与供水源连通。当然，也可以通过三通电磁阀将供水源、衣物处理剂投放装置6以及透气孔21连接。
基于上述的滚筒洗衣机，本发明还提供了一种蒸汽洗控制方法，如图1所示，本发明的蒸汽洗的控制方法包括：通过透气孔21向外筒2内注水；通过加热外筒2底部的水产生蒸汽以对内筒3内的衣物进行蒸汽洗。即，滚筒洗衣机在执行蒸汽洗程序时，通过透气孔21向外筒2内注水，注水完成后，可以通过设置在外筒2底部的加热装置(图中未示出)对外筒2底部的水加热，从而产生蒸汽，蒸汽通过形成在内筒3的筒壁上的孔31进入内筒3，以对内筒3内的衣物进行蒸汽洗。
本发明开发了透气孔21的第二功能。即，透气孔21可以起到两个作用，第一个作用，在通过衣物处理剂投放装置6向内筒3投放衣物处理剂和水的混合液时，内筒3和外筒2中的气体能够通过透气孔21排出，第二个作用，在向外筒2的底部注水时，供水源的水能够通过透气孔21进入外筒2内。
需要说明的是，为了避免供水源的水通过第一支管51进入衣物处理剂投放装置6内，可以在第一支管51与衣物处理剂投放装置6之间设置电磁阀，在向外筒2内注水时，使该电磁阀处于断开状态，或者，也可以在第一支管51与第二支管52的交汇处设置一个摆阀，在向外筒2内注水时，第二支管52内的水带动摆阀转动，以将第一支管51封堵，避免水进入第一支管51内，再或者，也可以使第一支管51倾斜向上设置，以防止第二支管52内的水流入第一支管51内，等等，本领域技术人员在实际应用中可以灵活地设置，只要能够防止第二支管52内的水流入第一支管51内即可。
此外，如图3所示，透气孔21一般靠近外筒2的后壁设置，使得从透气孔21进入的水能够在不经过内筒3内部的情形下进入到外筒2的底部。在一种优选的情形中，透气孔21对准内筒3的后壁与外筒2的后壁之间的间隙。即，在内筒3的后壁与外筒2的后壁之间具有一定的间隙，透气孔21正好形成在该间隙对应的外筒2的筒壁上，使得从透气孔21进入的水通过该间隙能够直接落到外筒2的底部。在另一种优选的情形中，透气孔21对准内筒3后部未设置孔31的部分。即，内筒3的筒壁上设置有很多孔31，但内筒3的后部有一部分(图4中标号32所指的部位)未设置孔31，透气孔21正好形成在该部分对应的外筒2的筒壁上，从透气孔21进入的水先落在内筒3的筒壁(这部分筒壁上未设置孔，水不会流入内筒3内)上，然后，沿着内筒3的筒壁流入外筒2的底部。在上述两种优选的情形中，滚筒洗衣机在执行蒸汽洗程序时，通过透气孔21向外筒2内注水时，能够防止水进入到内筒3内，从而能够防止将内筒3内的衣物打湿，进而能够避免影响对衣物的处理效果。
优选地，如图5和图6所示，透气孔21内安装有柱形喷水构件4，柱形喷水构件4的内部为中空结构，形成水道，柱形喷水构件4的顶部设置有进水口41，柱形喷水构件4的底部设置有出水口42，从进水口41进入的水沿着形成在柱形喷水构件4内部的水道流向出水口42，在组装好的情形下，进水口41位于外筒2的外侧，与供水源连通，出水口42位于外筒2的内侧，并且，出水口42朝向外筒2的后壁设置，在内筒3的后壁与外筒2的后壁之间具有一定的间隙，从出水口42喷出的水能够通过该间隙落入外筒2的底部，即，使得从出水口42喷出的水能够在不经过内筒3的内部的情形下进入外筒2的底部。通过这样的设置，能够有效地避免水进入到内筒3内。
优选地，本发明的滚筒洗衣机还包括定位结构，定位结构设置为能够防止柱形喷水构件4相对于透气孔21转动。即，在组装好后，通过定位结构能够将柱形喷水构件4定位至透气孔21内，在进水时，防止柱形喷水构件4相对于透气孔21发生转动，从而能够保证出水口42始终朝向外筒2的后壁。其中，定位构件可以外定位筋与定位槽相配合的结构，或者，也可以设置为定位块与定位口相配合的结构，再或者，还可以设置为卡扣结构，等等，此外，定位结构可以仅设置在外筒2上， 或者，定位结构也可以仅设置在柱形喷水构件4上，再或者，定位结构的一部分设置在外筒2上，另一部分设置在柱形喷水构件4上，这种对定位结构的具体结构形式以及具体设置位置的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
优选地，如图6所示，定位结构包括设置在透气孔21的内壁上的第一定位结构(图中未示出)以及设置在柱形喷水构件4的外壁上的第二定位结构43，第一定位结构与第二定位结构43相配合能够防止柱形喷水构件4相对于透气孔21转动。其中，第一定位结构为设置在透气孔21的内壁上的条形定位筋(图中未示出)，第二定位结构43为形成在柱形喷水构件4的外壁上的条形定位槽，条形定位筋与条形定位槽相适配。即，在组装好的情形下，设置在透气孔21的内壁上的条形定位筋正好卡置于形成在柱形喷水构件4的外壁上的条形定位槽内，从而能够防止柱形喷水构件4相对于透气孔21转动，并且，在组装时，通过条形定位筋和条形定位槽也能够保证柱形喷水构件4的出水口42朝向外筒2的后壁，提高了装配的准确性。
需要说明的是，第一定位结构也可以为形成在透气孔21的内壁上的条形定位槽，相应地，第二定位结构43为设置在柱形喷水构件4的外壁上的条形定位筋。即，将条形定位槽设置在透气孔21的内壁上，将条形定位筋设置在柱形喷水构件4的外壁上。
优选地，条形定位筋的横截面和条形定位槽的横截面均为正方形。通过这样的设置，使得条形定位筋不易从条形定位槽内脱出，从而提高了定位结构的可靠性。
优选地，如图5和图6所示，柱形喷水构件4的外壁上设置多个弹性筋44，在组装好的情形下，多个弹性筋44均弹性地抵靠在透气孔21的内壁上。即，在组装好的情形下，弹性筋44被挤塞在透气孔21的内壁和柱形喷水构件4的外壁之间，既能够防止柱形喷水构件4从透气孔21内脱出，又能够防止柱形喷水构件4相对于透气孔21转动。其中，弹性筋44为条形弹性筋44，多个条形弹性筋44沿柱形喷水构件4的周向布置。当然，弹性筋44也可以为其他的形状，例如，环形或者螺旋形等等，这种对弹性筋44的具体结构形状的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
优选地，如图5和图6所示，柱形喷水构件4的外壁上设置有环形挡筋45，环形挡筋45靠近进水口41设置，环形挡筋45的外径大于透气孔21的内径。即，在组装好的情形下，环形挡筋45能够抵靠在外筒2的筒壁上，以防止柱形喷水构件4从透气孔21内脱出而掉入外筒2内。
优选地，柱形喷水构件4采用橡胶材料制成。当然，柱形喷水构件4也可以采用其他材料制成，例如，塑料或者树脂等。
实施例二
基于背景技术指出的现有滚筒洗衣机的蒸汽洗的进水结构复杂，成本较高的问题。本发明提供了一种滚筒洗衣机，旨在提供一种结构简单的进水结构，能够在不经过内筒的内部的情形下，将水注入到外筒的底部。
具体地，如图7至图10所示，本发明的滚筒洗衣机包括箱体1，箱体1内设置有外筒2和内筒3，内筒3设置在外筒2的内部，外筒2相对于箱体1固定设置，内筒3能够在驱动装置(图中未示出)的驱动下，相对于外筒2转动，外筒2的前端成开口设置，内筒3由外筒2的前端开口处装入外筒2中，外筒2与内筒3的轴线重合，驱动装置设置在外筒2的后部，外筒2的筒壁上设置有通孔21，通孔21内安装有柱形喷水构件4，柱形喷水构件4的内部为中空结构，形成水道，柱形喷水构件4的顶部设置有进水口41，柱形喷水构件4的底部设置有出水口42，从进水口41进入的水沿着形成在柱形喷水构件4内部的水道流向出水口42，在组装好的情形下，进水口41位于外筒2的外侧，与供水源连通，出水口42位于外筒2的内侧，并且，出水口42朝向外筒2的后壁设置，在内筒3的后壁与外筒2的后壁之间具有一定的间隙，从出水口42喷出的水能够通过该间隙落入外筒2的底部，即，使得从出水口42喷出的水能够在不经过内筒3的内部的情形下进入外筒2的底部，从而在进水时，能够防止将内筒3内的衣物打湿，外筒2的底部设置有加热装置(图中未示出)，加热装置能够将外筒2底部的水加热，从而产生蒸汽，内筒3的筒壁上形成有多个小孔31，蒸汽通过这些小孔31进入到内筒3内，对内筒3内的衣物进行蒸汽洗。
需要说明的是，箱体1上设置有用于与外部供水源连接的接口，该接口一般设置在箱体1的顶部，为了便于与供水源连通，通孔21设置在外筒2的顶部。
优选地，如图7和图8所示，通孔21对准内筒3的后壁与外筒2的后壁之间的间隙。即，在内筒3的后壁与外筒2的后壁之间具有一定的间隙，通孔21正好形成在该间隙对应的外筒2的筒壁上。通过这样的设置，能够更有效地避免从通过进入的水进入到内筒3内，通孔21与外筒2的后壁的距离越小，水进入内筒3的几率越小。
优选地，通孔21为透气孔21。即，可以将柱形喷水构件4直接安装在外筒2的透气孔内，无需再在外筒2上单独开设一个通孔。
需要说明的是，如图7和图8所示，现有滚筒洗衣机的外筒2上均设置有透气孔21，透气孔21与滚筒洗衣机的衣物处理剂投放装置6连通，在通过衣物处理剂投放装置6向内筒3投放衣物处理剂和水的混合液时，内筒3和外筒2中的空气可以通过透气孔21排入衣物处理剂投放装置6内。并且，透气孔21一般设置在外筒2的顶部且靠近外筒2的后壁设置。即，透气孔21可以起到两个作用，在通过衣物处理剂投放装置6向内筒3投放衣物处理剂和水的混合液时，内筒3和外筒2中的气体能够通过透气孔21排出，在向外筒2的底部注水时，供水源的水能够通过透气孔21进入外筒2内。为了更好的实现上述功能，可以在透气孔21的外端(位于外筒2外侧的一端)安装一个三通管5，三通管5的第一支管51与衣物处理剂投放装置6连通，三通管5的第二支管52与供水源连通。为了避免供水源的水通过第一支管51进入衣物处理剂投放装置6内，可以在第一支管51与衣物处理剂投放装置6之间设置电磁阀，在向外筒2内注水时，使该电磁阀处于断开状态，或者，也可以在第一支管51与第二支管52的交汇处设置一个摆阀，在向外筒2内注水时，第二支管52内的水带动摆阀转动，以将第一支管51封堵，避免水进入第一支管51内，再或者，也可以使第一支管51倾斜向上设置，以防止第二支管52内的水流入第一支管51内，等等，本领域技术人员在实际应用中可以灵活地设置，只要能够防止第二支管52内的水流入第一支管51内即可。当然，也可以通过三通电磁阀将供水源、衣物处理剂投放装置6以及透气孔21连接。
优选地，本发明的滚筒洗衣机还包括定位结构，定位结构设置为能够防止柱形喷水构件4相对于通孔21转动。即，在组装好后，通过定位结构能够将柱形喷水构件4定位至通孔21内，在进水时，防止柱形喷水构件4相对于通孔21发生转动，从而能够保证柱形喷水构件4的出水口42始终朝向外筒2的后壁。其中，定位构件可以外定位筋与定位槽相配合的结构，或者，也可以设置为定位块与定位口相配合的结构，再或者，还可以设置为卡扣结构，等等，此外，定位结构可以仅设置在外筒2上，或者，定位结构也可以仅设置在柱形喷水构件4上，再或者，定位结构的一部分设置在外筒2上，另一部分设置在柱形喷水构件4上，这种对定位结构的具体结构形式以及具体设置位置的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
优选地，如图10所示，定位结构包括设置在通孔21的内壁上的第一定位结构(图中未示出)以及设置在柱形喷水构件4的外壁上的第二定位结构43，第一定位结构与第二定位结构43相配合能够防止柱形喷水构件4相对于通孔21转动。其中，第一定位结构为设置在通孔21的内壁上的条形定位筋(图中未示出)，第二定位结构43为形成在柱形喷水构件4的外壁上的条形定位槽，条形定位筋与条形定位槽相适配。即，在组装好的情形下，设置在通孔21的内壁上的条形定位筋正好卡置于形成在柱形喷水构件4的外壁上的条形定位槽内，从而能够防止柱形喷水构件4相对于通孔21转动，并且，在组装时，通过条形定位筋和条形定位槽也能够保证柱形喷水构件4的出水口42朝向外筒2的后壁，提高了装配的准确性。
需要说明的是，第一定位结构也可以为形成在通孔21的内壁上的条形定位槽，相应地，第二定位结构43为设置在柱形喷水构件4的外壁上的条形定位筋。即，将条形定位槽设置在通孔21的内壁上，将条形定位筋设置在柱形喷水构件4的外壁上。
优选地，条形定位筋的横截面和条形定位槽的横截面均为正方形。通过这样的设置，使得条形定位筋不易从条形定位槽内脱出，从而提高了定位结构的可靠性。
优选地，如图9和图10所示，柱形喷水构件4的外壁上设置多个弹性筋44，在组装好的情形下，多个弹性筋44均弹性地抵靠在通 孔21的内壁上。即，在组装好的情形下，弹性筋44被挤塞在通孔21的内壁和柱形喷水构件4的外壁之间，既能够防止柱形喷水构件4从通孔21内脱出，又能够防止柱形喷水构件4相对于通孔21转动。其中，弹性筋44为条形弹性筋44，多个条形弹性筋44沿柱形喷水构件4的周向布置。当然，弹性筋44也可以为其他的形状，例如，环形或者螺旋形等等，这种对弹性筋44的具体结构形状的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
优选地，如图9和图10所示，柱形喷水构件4的外壁上设置有环形挡筋45，环形挡筋45靠近进水口41设置，环形挡筋45的外径大于通孔21的内径。即，在组装好的情形下，环形挡筋45能够抵靠在外筒2的筒壁上，以防止柱形喷水构件4从通孔21内脱出而掉入外筒2内。
优选地，柱形喷水构件4采用橡胶材料制成。当然，柱形喷水构件4也可以采用其他材料制成，例如，塑料或者树脂等。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
