Description

滚筒洗衣机及其清洗方法 技术领域
本公开涉及洗衣机技术领域，例如涉及一种滚筒洗衣机及其清洗方法。
背景技术
相关技术中的滚筒洗衣机的内筒和外筒之间对用户来说是一个封闭区域，无法直接进行清洗。在洗衣时，污水在内筒和外筒之间的区域串流，经过一段时间使用后，会在此区域内堆积污垢，若长时间不进行清理，则会在洗衣过程中对衣物造成二次污染，影响用户的身体健康，并且还会导致洗衣机内产生异味。
相关技术中对滚筒洗衣机的内筒和外筒的清理方法有：1.通过水流冲刷内筒，减少内筒上附着的污垢；2.定期使用槽洗净清洁剂对洗衣机进行药剂清洗，去除污垢。而上述水流冲刷方式，并不能干净和彻底地对洗衣机进行清洗；药剂清洗方式耗费时间长。
因此，亟需一种避免在内筒和外筒之间的区域附着、沉积污垢的滚筒洗衣机及其清洗方法。
发明内容
本公开提出一种避免在内筒和外筒之间的区域附着、沉积污垢的滚筒洗衣机及其清洗方法。
本公开采用以下技术方案。
本公开一方面提供一种滚筒洗衣机，包括内筒、外筒和排水装置，外筒上设有进水孔和出水孔，内筒上设有排水孔，在外筒和内筒之间设有环形隔离通道，环形隔离通道与外筒或内筒连接；位于内筒和外筒之间且位于环形隔离通道之外的区域，与环形隔离通道内的区域不连通；进水孔和出水孔设置在外筒上对应环形隔离通道的环形区域内，排水孔设置在内筒上对应环形隔离通道的环形区域内，内筒上除对应环形隔离通道的环形区域之外的区域是无孔结构；排水装置与出水孔连接；内筒的前端敞口通过隔离件与外筒的前端敞口隔离开。
可选地，环形隔离通道与外筒连接，环形隔离通道与内筒之间设有密封件， 密封件与环形隔离通道连接。
可选地，环形隔离通道包括两个间隔设置的环形壁板，密封件包括两个密封圈，两个密封圈与两个环形壁板一一对应的连接。
可选地，环形隔离通道设置在内筒的外周壁和外筒的内周壁之间，排水孔分布在内筒的侧壁的整个圆周上。
可选地，环形隔离通道设置在内筒的后端的外周壁上，排水孔设置在内筒的侧壁的后端。
可选地，隔离件为洗衣机门。
可选地，在洗衣机门与内筒之间设有环形密封件。
可选地，在环形隔离通道中设有喷淋装置，喷淋装置的喷射方向为朝向环形隔离通道内部。
可选地，内筒的内周壁上设有导流结构。
本公开另一方面提供一种上述任一项滚筒洗衣机的清洗方法，包括如下步骤：打开排水装置，通过进水孔向环形隔离通道中注水，水流冲刷环形隔离通道后经过外筒上的出水孔由所述排水装置排出。
本实施例的滚筒洗衣机，通过隔离件和环形隔离通道的设置以及将内筒除对应环形隔离通道的其他区域构造成无孔结构，使外筒和内筒之间的空间与内筒内部完全隔离开，进而内筒和外筒之间不会形成污水串流，由此也就不会在外筒和内筒之间的区域中附着、堆积污垢。环形隔离通道的面积比外筒的面积小很多，清洗简便，不易附着、堆积污垢。因此，该滚筒洗衣机在洗衣过程中可以减少对衣物造成二次污染，可以减少洗衣机内由于污垢堆积而产生的异味。
在本实施例的滚筒洗衣机中，可选地，环形隔离通道与外筒连接，环形隔离通道与内筒之间设有密封件，密封件与环形隔离通道连接。一方面，环形隔离通道与外筒连接后，在洗衣机工作时不会转动，相较于与内筒连接会降低电量损耗；另一方面，使用密封件可以保证环形隔离通道与内筒之间的接触和密封，尤其是在内筒转动且会振动的情况下，可以保证环形隔离通道的隔离效果。
在本实施例的滚筒洗衣机中，可选地，环形隔离通道设置在内筒的后端，排水孔设置在内筒的侧壁的后端，可有效降低振动。
在本实施例的滚筒洗衣机中，可选地，在环形隔离通道中设有喷淋装置，喷淋装置的喷射方向为朝向环形隔离通道内部。在清洗过程中，通过喷淋装置可以有针对性的冲刷环形隔离通道内部(包括环形隔离通道的侧壁、外筒的内 周壁和内筒的外周壁)，清洗效果好，并尽可能的减少了进入内筒中的水量。
本实施例的滚筒洗衣机的清洗方法，包括如下步骤：打开排水装置，通过进水口向环形隔离通道中注水，水流冲刷环形隔离通道后经过外筒上的出水孔有由排水装置排出。该滚筒洗衣机中外筒和内筒之间的空间与内筒内部完全隔离开，不会在外筒和内筒之间的区域中附着、堆积污垢。该滚筒洗衣机仅对环形隔离通道进行清洗即可，而且由于环形通道的面积小，很容易被冲洗干净，该滚筒洗衣机可以减少在洗衣过程中对衣物造成的二次污染，也可以减少由于污垢堆积而导致洗衣机内产生的异味。

实施例一
参照图1和图2，在本实施例中，滚筒洗衣机包括内筒1、外筒2和排水装置11。在外筒2和内筒1之间设有环形隔离通道6，环形隔离通道6与外筒2或内筒1连接，也就是，环形隔离通道6可以与内筒1连接而在洗涤时随内筒1旋转，也可以与外筒2连接而在洗涤时随外筒2保持静止。外筒2上设有进水孔3和出水孔4，进水孔3和出水孔4设置在外筒2上位于环形隔离通道6的环形区域内。内筒1上设有排水孔5，排水孔5设置在内筒1上位于环形隔离通道 6的环形区域内，内筒1上除对应环形隔离通道6的环形区域之外的区域是无孔结构。并且，内筒1的前端敞口通过隔离件与外筒2的前端敞口隔离开，其中前端敞口可以是内筒1和外筒2中的将待洗物放入内筒1的入口；环形隔离通道(6)将内筒(1)和外筒(2)之间的空间分成了两部分，一部分是环形隔离通道(6)的内部空间，另一部分是环形隔离通道(6)外的空间，环形隔离通道(6)的内部空间与环形隔离通道(6)外的空间不连通。外筒2的进水孔3与进水管10连接。排水装置11可以为上排水装置或下排水装置，在本实施例中，采用上排水装置。上排水装置包括与外筒2的出水孔4连通的排水管110，在排水管110上设有排水泵111。通过进水管10经进水孔3向环形隔离通道6中注水，水经过环形隔离通道6和排水孔5进入内筒1。排水时，打开排水泵111，内筒1中的水通过排水孔5进入环形隔离通道6，再经过出水孔4排入排水管110。
由此，通过隔离件和环形隔离通道6的设置以及将内筒1除位于环形隔离通道6的环形区域内的其他区域构造成无孔结构，使外筒2和内筒1之间的空间与内筒1内部完全隔离开，进而内筒1和外筒2之间不会形成污水串流，避免了在外筒2和内筒1之间的区域中附着、堆积污垢。环形隔离通道6的面积比外筒2的面积小很多，清洗简便，进而不易附着、堆积污垢。因此，本实施例的滚筒洗衣机可以减少在洗衣过程中对衣物造成的二次污染，也可以减少由于污垢堆积而导致洗衣机内产生的异味。
参照图1和图2，在本实施例中，环形隔离通道6设置在内筒1的外周壁(内筒1的侧壁的外表面)和外筒2的内周壁(外筒2的侧壁的内表面)之间，排水孔5分布在内筒1的侧壁的整个圆周上。可以设置一圈或多圈排水孔5，或者排水孔5可交叉布置。但排水孔5仅能设置在环形隔离通道6的区域内，以保证内筒1的其他区域是无孔结构，进而保证内筒1中的水不会进入外筒2和内筒1之间的区域。
可选地，环形隔离通道6与外筒2连接，在洗衣机工作时环形隔离通道6不会转动，相较于环形隔离通道6与内筒1连接会降低电量损耗。环形隔离通道6与内筒1之间可以设有密封件7，密封件7与环形隔离通道6连接，即，环形隔离通道6的面向内筒1的侧面上设有密封件7，以保证环形隔离通道6将内筒1和外筒2之间的区域(除去环形隔离通道6所占用的区域)与环形隔离通道6的环形区域隔离开，在内筒1转动且会振动的情况下，可以保证隔离效果。
可选地，环形隔离通道6包括两个间隔设置的环形壁板61、62，密封件7包括两个密封圈71、72，两个密封圈71、72与两个环形壁板61、62一一对应的连接(例如，采用粘接等固定连接方式)。环形隔离通道6的与进水孔3和出水孔4连通，环形隔离通道6的与内筒1的排水孔5连通，两个环形壁板61、62限定水仅能在二者之间流动而不能进入外筒2和内筒1之间的区域。可选地，两个环形壁板61、62平行设置。
可选地，在其他实施例中，环形隔离通道6也可连接在内筒1上而随内筒1一起运动，此时密封件7设置在环形隔离通道6与外筒2之间。
可选地，环形隔离通道6设置在内筒1的后端，排水孔5设置在内筒1的侧壁的后端。也就是，内筒1的排水孔5的位置靠近与内筒1连接的转轴，这样可有效降低振动。可选地，上述“内筒1的后端”是指沿内筒1的纵向长度的1/7处(例如，以内筒1与转轴连接处为纵向长度的起点)及以后的部分。在其他实施例中，根据洗衣机内筒1、外筒2及其他部件的设置，“内筒1的后端”的具体位置只要是可以降低振动的位置即可。
此外，在本实施例中，隔离件可以为洗衣机门8。在关上洗衣机门8时，洗衣机门8密封内筒1的前端敞口以及外筒2的前端敞口，以将内筒1的前端敞口与外筒2隔离开。洗衣机门8距离内筒1较近的部分定义为内筒门81，内筒门81用于密封内筒1的前端敞口，在内筒门81与内筒1之间设有环形密封件9，该环形密封件9可选为密封环，密封环固定在内筒门81上。洗衣机门8距离内筒1较远的部分定义为外筒门82，在外筒门82上固定有密封窗垫13，以密封外筒2和洗衣机的箱体14。可选地，洗衣机门8为一体件，方便开门和关门操作。
可选地，隔离件可以是专门用于隔离内筒1和外筒2的部件，例如，可以是在内筒1的前端和外筒2的前端之间的区域设置的挡环等。
可选地，在本实施例中，在环形隔离通道6中设有喷淋装置，图3是本实施例提供的一种喷淋装置的结构示意图，喷淋装置15的喷射方向为朝向环形隔离通道6内部。在清洗过程中，通过喷淋装置15能够有针对性的冲刷环形隔离通道6内部(包括环形隔离通道的侧壁、外筒的内周壁和内筒的外周壁)，清洗效果好，并尽可能的减少了进入内筒1中的水量。为了向喷淋装置15送水，可以设有与喷淋装置15连接的水管。
可选地，参考图4，在内筒1的内周壁上设有导流结构12。在本实施例中， 导流结构12包括多个凸起，凸起的分布整体呈螺旋状。在其他实施例中，导流结构12可为导流槽等，只要能够将内筒1中的水导向排水孔5即可。
参考图1，内筒1内部形成第一区域B，环形隔离通道6形成第二区域A，内筒1和外筒2之间(环形隔离通道6之外区域)形成第三区域C，第一区域B通过排水孔5与第二区域A连通，第一区域B与第三区域C不连通，第二区域A也与第三区域C不连通。
下面本实施例的滚筒洗衣机的工作过程如下。
洗涤时，关闭洗衣机门8封闭内筒1，自来水通过进水管10经进水孔3进入环形隔离通道6，然后经排水孔5进入内筒1内部至合适水位，此时第三区域C中没有水进入，仅第一区域B和第二区域A中有水。
进水完毕，电机带动内筒1按一定转停比的程序进行洗涤。
洗涤结束后，打开排水泵111排水，内筒1中的水通过排水孔5进入环形隔离通道6，然后经过出水孔4进入排水管110排走。
清洗时，自来水通过喷淋装置15进入环形隔离通道6，对环形隔离通道6的侧壁、以及环形隔离通道6对应的外筒2内壁区域和内筒1外壁区域进行冲洗，将污水彻底从出水孔4冲出。
清洗结束后，内筒1脱水，内筒1内周壁上的导流结构12将水引至排水孔5，后经环形隔离通道6和出水孔4排出。
重复以上过程进行漂洗至洗涤结束。
实施例二
在本实施例中，描述实施例一中的滚筒洗衣机的清洗方法，参考图5，该清洗方法包括如下步骤：
在步骤510中，打开排水装置11。
在步骤520中，通过进水孔3向环形隔离通道6中注水，水流冲刷环形隔离通道6后经过外筒2上的出水孔4由排水装置11排出。
滚筒洗衣机的环形隔离通道6面积小，很容易被冲洗干净，通过上述步骤可清洗干净环形隔离通道6的侧壁、环形隔离通道6对应的外筒2内壁区域和内筒1外壁区域，本实施例的滚筒洗衣机可以减少在洗衣过程中对衣物造成的二次污染，也可以减少由于污垢堆积导致洗衣机内产生的异味。
在安装有喷淋装置15时，可以通过喷淋装置15向环形隔离通道6注水。而在没有喷淋装置15时，可以通过进水管10向进水孔3注水来冲洗环形隔离 通道6。
工业实用性
本公开提供一种滚筒洗衣机及其清洗方法，可以解决在洗衣过程中，由于污垢堆积而导致对衣物造成的二次污染，以及减少洗衣机内由于污垢堆积而产生的异味。
