Description

一种洗干一体式洗衣机及其烘干方法 技术领域
本发明属于洗衣机领域，具体地说，涉及一种洗干一体式洗衣机及其烘干方法。
背景技术
洗衣机大体上可分为波轮式、搅拌式及滚筒式洗衣机。波轮式洗衣机通过将洗涤槽的中央的波轮左右旋转，从而进行洗涤操作。搅拌式洗衣机通过将洗涤槽中央的旋转翼片左右方向旋转，从而利用水流和洗涤物之间的摩擦力进行洗涤操作。滚筒式洗衣机通过旋转滚筒，对衣物进行摔打，从而进行洗涤操作。
洗衣机的机壳内设置有外筒和内筒，内筒作为洗涤的重要部件，通常在筒壁上设置孔，用于向内筒中进洗涤水或者用于对内筒中的衣物进行脱水。内筒和外筒之间由于洗涤水的长时间流动积累会滋生大量污垢、细菌，对衣物产生二次污染，不利于人体的健康，由此提出了设置无孔内筒的洗衣机。
而随着居民生活水平和品味的提升，现有洗衣机不仅需要满足洗涤的需求，还需要满足对衣物洗涤后烘干的需求，因此，如何对设置有无孔内筒的洗衣机进行烘干设置成为了研发的热点。
申请号为201410708103.3的中国专利公开了一种节水滚筒洗衣机，包括外筒、设置在外筒内的内筒和连通内筒的烘干风路，内筒和外筒同轴安装在中心轴上，所述的内筒为无孔内筒，内孔的内壁安装多个提升装置；所述的中心轴的内部设置中空结构，所述的烘干风路和提升装置分别连通中空结构，提升装置上设置多个出水口。当烘干程序启动时，烘干风机启动，将热风经烘干风路-中空结构-连接管路-提升装置-出水口均匀分吹到衣物上，但专利中的排水管路与烘干风路均与中空结构6连接，通过电磁阀切换相应的程序，烘干风在进出内筒时需要不断切换电磁阀，进风和排风不能同时进行，不利于衣物的快速干燥。
有鉴于此特提出本发明。

本发明的一种洗干一体式洗衣机及其烘干方法适用于滚筒洗衣机或者波轮洗衣机，下面以滚筒洗衣机为例进行详细说明。
实施例一
如图1和图2所示，本实施例所述的一种洗干一体式洗衣机，其特征在于，包括：内筒1，洗涤时独立盛放洗涤水，避免了内筒1外部积存和过流洗涤水造成的污垢堆积和细菌滋生的问题；烘干系统，用于烘干所述内筒1中的衣物，提升了用户的生活品质；所述的烘干系 统中包括加热模块5，所述的加热模块5用于加热所述的内筒1，为所述的烘干系统提供热量，使进入内筒1中的干燥烘干风变为湿热烘干风，通过烘干风将衣物中中的水分带走，完成干燥衣物的目的。
所述的加热模块5为电磁加热模块，所述的内筒1为金属材质构成，以受到所述的加热装置产生的磁场而产生涡流效应以发热，内筒1受热温度升高，进而加热内筒1中的衣物和流经内筒1的烘干风，内筒1中的衣物受热，水分蒸发，烘干风在温度升高的同时，携带蒸发出的水分流动，增强了烘干风与衣物之间的对流换热，提高了烘干效率。
洗衣机包括同轴套设在内筒1外部的外筒2和设置在外筒外部的壳体，所述的加热模块5设置在内筒1或外筒2或壳体上；为了避免洗涤水对加热模块5产生侵蚀和便于相关电路的配置，优选的，将所述的加热模块设置在外筒2上；更为优选的，所述的加热模块5设置在外筒2的最低处。
为了增强加热效果，所述的加热模块5中至少包括一个电磁加热模块，所述的加热模块5至少为一个，当设置多个加热模块5时，加热模块5可以均布在外筒2上也可以集中布置。所述电磁加热模块包括一塑料外壳，塑料外壳内部中空围成一侧敞口的安装腔，安装腔内安装有电磁发生器；塑料外壳固定安装于外筒外侧，且塑料外壳的安装腔敞口朝向外筒内部设置。
在一种方案中，为了实现内筒1中的衣物烘干，洗衣机上包括进风结构8，分别连通所述的烘干系统和内筒1；出风结构12，设置在所述的内筒1上，与所述的烘干系统连通；烘干系统的烘干风由进风结构8进入内筒1进行衣物烘干，内筒1内的湿热烘干风由出风结构12返回至烘干系统，对内筒1内的衣物进行循环烘干。
烘干系统中设有冷凝模块和风机，当内筒1中的湿热烘干风经出风结构12排到内筒1的外部空间后，在风机的抽吸作用下进入烘干系统中；经过冷凝模块的作用析出水分，湿热烘干风变为干燥烘干风，然后在风机的作用下经进风结构进入内筒1内，在加热模块5的作用下，干燥烘干风再次变为湿热烘干风经出风结构12排出进入烘干系统中，如此循环对衣物进行烘干。
循环烘干的烘干方法能够最大程度利用烘干风中的余热热量，系统节能高效。
作为本实施例的进一步的方案，烘干系统中的风机可以为可逆风机，烘干系统中设置能够切换风机转向的调节装置，能够调节烘干风的流动方向。
在另一种方案中包括进风结构12，分别连通所述的烘干系统和内筒1；直排风结构4， 与外界连通；出风结构12，设置在所述的内筒1上，与所述的直排风结构4连通；烘干系统的烘干风由进风结构8进入内筒1进行衣物烘干，内筒1内的湿热烘干风由出风结构12进入直排风结构4中，直排风结构4中设置冷凝模块，对湿热烘干风进行冷凝后，直接排入外界环境中。
本实施例中，烘干系统中设有风机6，在风机6的作用下，将风机6附近的空气抽吸进烘干风路中，干燥烘干风经中心轴9进入内筒1中，与内筒1中的衣物充分接触，在加热模块5的作用下，干燥烘干风变为湿热烘干风，携湿热烘干风经出风结构12进入内筒1的外部空间中；内筒1外部的湿热烘干风在风机的作用下进入所述的直排风结构4中，在直排风结构4中的冷凝模块的冷凝作用下，湿热烘干风的温度和湿度降低，当烘干风排入外界环境中时提高用户的舒适度，直排式烘干方式避免湿热烘干风长时间的逗留在内筒1的外部空间中，出现细菌滋生的问题，同时直排式的烘干方式，系统的结构简单，产品成本降低，有利于产品的推广。
下面对洗衣机的进风结构8进行详细介绍：
如图1所示，内筒1具有相对设置的内筒口和内筒底13，所述的进风结构8设置在内筒底13上，所述的内筒口上设置封闭内筒口的内筒门11，出风结构12设置在内筒门11上，进风结构8和出风结构12的位置相对设置，使内筒1中的烘干风形成对流，气流流通顺畅。
进风结构8包括中心轴9，所述的中心轴9为中空轴，所述的内筒1设置在所述的中心轴9上，中心轴9的中空结构构成流道并分别与洗衣机的内筒1和烘干系统的送风管路连通，实现了向内筒1内进气的使用功能，令内筒1可以顺畅进气。
所述的进风结构8还包括位于内筒1中与所述的中心轴9一端连通的散流元件80，所述的散流元件80上设有朝向不同方位的出风口81，用于对烘干风进行分流散射，使烘干风快速充满内筒1空间，增大了烘干风与衣物的接触面积，提高了衣物的烘干效率。
结合图1、图3和图4，所述的散流元件80具有靠近内筒底13的底壁84，所述的底壁84与内筒底13平行，所述的底壁84上设有与中心轴9连通的连接短管83；还具有与所述的底壁84连接向内筒1内部呈球面凸出的散流壁82，所述的出风口81与连接短管83连通且均布在散流壁82上。
散流壁82设置在所述的内筒1的内部，通过连接短管83呈碗状倒扣安装于内筒底13上，散流壁82与底壁84之间内为中空的进气腔，所述的出风口81为与进气腔连通的镂空孔，用来连通进气腔与内筒1。
通过在洗衣机内筒底13上设置散流元件80，使得烘干风经多个朝向不同方向的出风口81与内筒1相连通，以避免进风口结构单一而被堵塞、造成洗衣机进风不畅情况的发生。同时，通过在内筒底13中心设置一散流元件80，以使得进风气流受散流壁82阻挡而产生发散溅射，进而提升进风气流的覆盖面积、提升衣物的烘干效果。同时，散流元件80内的进气腔对进风气流起到缓冲作用、提升进气的顺畅性。
在洗衣机进水洗涤过程中，散流元件80的设置有利于对水流进行分散，提高洗涤水对衣物的浸湿效率，同时避免了衣物堵塞进水口，提高进水效果。
本实施例中，所述的散流元件80靠近内筒底13的底壁84中心设置有连接短管83，所述的连接短管83为与散流元件80内的进气腔连通的中空管，所述的连接短管83与所述的中心轴9连通，便于烘干系统中的烘干风进入内筒1中，提升进气的顺畅性。
下面对洗衣机的出风结构12进行详细介绍：
结合图1、图5至图8，所述的内筒门11上设有用于烘干风流通的透气口，所述的出风结构12为阻水透气的透气元件，透气元件安装在透气口上。透气元件的设置一方面为烘干风提供了循环的通路，另一方便透气元件能够对内筒1内外的压力进行平衡，使烘干风的流动更加顺畅，在洗衣机执行洗涤程序时，使洗涤水的进水流畅。
透气元件12包括阀座121和透气膜123，所述的阀座121安装在内筒门的透气口上，所述的透气膜123安装在所述的阀座121上，覆盖整个透气口；为了避免衣物洗涤烘干过程中对透气膜123发生碰撞摩擦，造成透气膜123的脱落或者磨损，透气膜设置在阀座121位于内筒门11外部的一侧壁面上。
透气膜123上设有交叉设置的窄缝124，所述的窄缝124在压力作用下可开启。
本实施例中，所述透气膜123由弹性材质构成，以在两侧压差作用下自身产生变形以封闭、或打开透气膜123上所设的窄缝124；优选的，透气膜123上的窄缝124呈“十”字形，且“十”字形的中心与透气口的中心相重合设置。
一种洗干一体式洗衣机的烘干方法，当洗衣机执行烘干程序后，洗衣机的控制系统控制所述的加热模块5启动，所述的内筒1受热温度升高，进而加热所述的内筒1中的衣物和流经内筒1的烘干风，进入内筒1内的干燥烘干风变为湿热烘干风，直接排入外界环境或者重新返回烘干系统中。
实施例二
本实施例中介绍了一种出风结构12的安装结构，如图5至图8所示，所述出风结构12 包括一透气膜123，透气膜123上设有仅供气体流经的窄缝124；透气膜123装配于安装结构上，所述安装结构包括一安装于内筒1的阀座121，阀座121包括具有多个镂空部122的盘状主体，盘状阀座121的外周与内筒1上的透气口的壁面密封固定；阀座121远离内筒1的一侧覆盖铺设有透气膜123，透气膜123上设有仅供气体流经的窄缝124。透气膜123与盘状阀座121之间相距一定间距，以留出为透气膜123变形的活动空间。
通过上述设置，使透气膜123可固定装配于内筒1上，实现了透气膜123的固定安装；同时，由于阀座121的阻挡作用，避免了透气膜与筒内衣物及水流的直接接触，进而防止了透气膜123直接受冲击而损坏情况的产生。
本实施例中，阀座121包括同轴设置、不等径的两圈环形支撑筋，外圈环形支撑筋和内圈环形支撑筋之间经多条沿径向延伸的连接筋相连，各连接筋等间隔角度的均匀排布，各连接筋的两端分别与外圈环形支撑筋的内周和内圈环形支撑筋的外周相连接。进一步优选的，内圈环形支撑筋相对外圈环形支撑筋靠近滚筒内部设置，使连接筋呈向内倾斜的延伸。
本实施例中，外环支撑筋沿轴向具有一定延伸宽度，外环支撑筋靠近滚筒内部的一侧与连接筋相连、远离内筒1的一侧铺设覆盖有透气膜123。
本实施例中，所述透气膜123由弹性材质构成，以在两侧压差作用下自身产生变形以封闭、或打开透气膜123上所设的窄缝124；优选的，透气膜123上的窄缝124呈“十”字形，且“十”字形的中心与透气口的中心相重合设置。
本实施例中，所述的透气膜123可以为如图7所示呈平板状的、可向两侧双向流动气流的双向透气膜；也可以为如图6所示呈弧状的、仅能相凸出侧单向流动气流的单向透气膜，单向透气膜的安装方向可以根据气流流动方向自行调整。
本实施例中，内筒1上的设有透气口，阀座121对应覆盖装配于透气口中，阀座121的外周与透气口的内壁相密封贴合；优选的，阀座121的外环支撑筋与透气口内壁相对应密封贴合；进一步优选的，外环支撑筋的内外两侧分别设有向外弯折的翻边，翻边对应贴合于内筒1内外两侧，使阀座121紧固装配于内筒1上。
本实施例中的透气膜123在洗衣机的注水过程中，使不具有脱水孔的内筒内部可与外界相互换气，以调节滚筒内部压力，实现向滚筒内顺畅进水、或向外顺畅排水的目的。
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做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。
