Description

一种洗衣机及其控制方法 技术领域
本发明涉及洗衣设备技术领域，具体地，涉及一种洗衣机及其控制方法。
背景技术
洗衣机作为人们日常生活中使用最为广泛的一种家用电器，帮助人们摆脱了洗衣的烦恼，给人们带来了极大的便利。但是现有洗衣机一般都包括内筒和外筒，内筒的桶壁上分布多个脱水孔，而在洗涤过程中，内筒与外筒之间的洗涤水不会被利用，造成该部分洗涤水的浪费，且洗涤过程中产生的脏污会随着水流进入内筒与外筒之间而被积累，随着长时间的使用，脏污的累积会影响洗涤效果，降低用户使用体验。
为了解决上述问题，现有一种具有无孔内筒的滚筒洗衣机，无孔内筒的筒口安装可开启/关闭的内筒门，从而形成可独立盛放洗涤水的内部腔室，这样在洗涤和漂洗过程中，洗涤水被盛放在内筒中，内筒与外筒之间无水，解决了内筒与外筒之间的脏污问题，同时节省了洗涤用水量。由具有无孔内筒的滚筒洗衣机的结构特点可知，在洗涤和漂洗过程中，保持内筒门的密封性性是形成可独立盛放洗涤水的内筒内部腔室的关键，而且，在内筒高速转动的脱水过程中，若内筒门未锁定或者锁定不到位，将会导致严重的安全事故。因此，内筒门的关闭到位检测是具有无孔内筒的滚筒洗衣机能否正常运行的关键。
申请人了解到，本行业有专利申请针对这一问题给出了相应的解决方案，例如在外筒或者壳体上设置用于检测内筒门是否关闭到位位置检测装置。具体地，在内筒门上设置磁铁，在外筒上设置干簧管，当内筒门关闭到位时，干簧管受到内筒门上的磁铁的作用闭合产生内筒门闭合信号。该方案从原理上看似乎可行，但实际是会存在很多的问题的，比如干簧管的检测精度较低，而内筒门锁定和解锁的两个状态的内筒门位移差较小，干簧管和电磁铁的规格型号的选择、位置的设置均比较复杂，且会存在有内筒门关闭但却未锁定的状态很难被干黄管监测到，存有安全隐患。
因此，本申请旨在解决无孔内筒的内筒门锁定是否到位的问题。
有鉴于此，特提出本发明。
发明内容
为了解决上述问题，本发明的第一发明目的是提供一种洗衣机，具体地，采用了如下的技术方案：

本发明的第二发明目的是提供一种洗衣机的控制方法，具体地，采用了如下的技术方案：
一种洗衣机的控制方法，洗衣机接收洗衣指令，门锁检测装置检测内筒门锁是否锁定，若是，则执行洗衣指令，若否，则停止执行洗衣指令。
本发明提供一种内筒前开式滚筒洗衣机，内筒上设置内筒门，实现内筒封闭空间洗涤，避免内筒的衣物出来的可能，及衣物受压及摔打导致由内筒流出或者飞溅出水，避免了内、外筒之间污垢附着的可能，真正实现了滚筒的桶间无水。
本发明的洗衣机具有内筒门锁锁定到位的门锁检测装置，确保内筒门锁定到位，确保锁定判定准确率100％，由于滚筒脱水转速会达到1600转/分钟，内筒上的内筒门如果未能锁定好，将会发生安全事故，极大的提高了机器的安全性，用户健康及用户体验。
本发明通过设置门锁触发装置，在内筒门锁锁定时与锁舌发生联动，门锁触发装置可将内筒门锁锁定时锁舌的位移放大，更易被门锁检测装置检测到，确保检测的准确性。

内筒门锁，用于锁定内筒门6保持关闭状态；
门锁触发装置，在内筒门锁锁定过程中与其联动；
以及门锁检测装置3；用于检测门锁触发装置判断内筒门锁是否锁定。
本实施例公开一种无孔内筒前开式结构的滚筒洗衣机，内筒1是无孔结构的，与内筒1紧固连接的内筒轴穿过所示轴承并连接驱动电机。内筒1前部筒口上安装可开启/闭合的内筒门6，进而实现内筒1具有独立盛放洗涤水的洗涤腔室。因此，本实施例的洗衣机结构简单，能够无需在内筒与外筒之间填充洗涤/漂洗水而极大的减少了洗衣机的洗涤用水量，避免了内筒与外筒之间污垢附着的可能，极大的提高了用户健康及用户体验，极大的节约了水资源。
本实施例的滚筒洗衣机具有外壳，外壳包括：上台面板，前面板，后背板和底板。底板上安装固定了底脚，用于支撑整个洗衣机。外壳内部内筒旋转，优选的是设置了提升筋，不断的提升跌落摔打衣物，以便洗净衣物。
由具有无孔内筒的滚筒洗衣机的结构特点可知，在洗涤和漂洗过程中，保持内筒门的密封性性是形成可独立盛放洗涤水的内筒内部腔室的关键，而且，在内筒高速转动的脱水过程中，若内筒门未锁定或者锁定不到位，将会导致严重的安全事故。本实施例的洗衣机通过采用门锁检测装置对内筒门锁进行检测，因为内筒门锁的锁定与否直接关系到内筒门是否关闭到位，因此，门锁检测装置3可更加直接的检测到内筒门的状态，从根本上杜绝内筒门关闭不到位的情况。
由于内筒门锁定和解锁的两个状态的锁舌17发生的位移差较小，因此要想准确的检测到锁舌的动作，对于门锁检测装置的检测精度要求较高，但这必定将会增加门锁检测装置的成本，本实施例的洗衣机为了尽量降低门锁检测装置的成本且保证检测精度的前提下，还包括门锁触发装置，门锁触发装置在内筒门锁锁定过程中与内筒门锁联动进入门锁检测装置3的检测范围内。
本实施例通过设置门锁触发装置，在内筒门锁锁定时与锁舌发生联动，门锁触发装置可将内筒门锁锁定时锁舌的位移放大，更易被门锁检测装置3检测到，确保检测的准确性。
进一步地，本实施例所述的门锁触发装置包括与内筒门锁联动的活动件13、被门锁 检测装置3检测的感应件16以及传动连接活动件13和感应件16的传动机构，所述的感应件16在内筒门6锁锁定时脱离门锁检测装置3的检测范围。
本实施例的传动机构可以具有放大活动件13位移的作用，进一步将锁舌的位移在感应件16上进行放大以便于门锁检测装置3进行感应检测，极大的降低成本增加检测准确性。
为了实现门锁触发装置将内筒门锁的锁定位移放大，本实施例所述的内筒门锁包括安装在内筒门6上的锁舌17和安装在内筒1的筒口上的锁座5；所述的传动机构为杠杆机构，杠杆机构包括固定在锁座5内的杠杆轴14和绕杠杆轴14可转动的杠杆18，所述的活动件13和感应件16分别设置在杠杆18的动力臂端和阻力臂端。
优选地，所述杠杆18的阻力臂长于动力臂。
本实施例门锁触发装置的活动件13在内筒门锁锁定时随着锁舌联动，可将锁舌较小的位移进行放大，从而实现对内筒门锁锁定状态时的准确检测。
本实施例的杠杆机构可以将锁舌传递给活动件13的位移进一步放大，进一步提升门锁检测装置3的检测准确性。进一步地，本实施例所述的门锁触发装置包括用于感应件回位至门锁检测装置的检测范围内的弹性件。本实施例门锁触发装置的弹性件15在内筒门锁锁定过程中，活动件与锁舌联动压缩弹性件15，弹性件15发生弹性变形，当内筒门锁解除锁定时，活动件不再受到锁舌17的止抵，弹性件15恢复形变推动活动件13复位，以进行下一次锁定过程的检测。
作为本实施例的一种实施方式，所述的弹性件15为安装在杠杆轴14上的扭簧，扭簧的两端分别止抵在杠杆18的动力臂和阻力臂上。
或者，所述的弹性件15为设置在活动件13与锁座5之间的压缩弹簧。
或者，所述的弹性件15为设置在感应件16与锁座5之间的拉伸弹簧。
进一步地，本实施例所述的锁座5包括座体和设置在座体内的锁定件，所述杠杆的动力臂端位于锁定件处，所述的锁舌锁定在锁定件内止抵在活动件上推动其运动。
优选地，所述的锁止件上开设开口，所述活动件13的至少部分在弹性件的作用下由开口伸入锁定件内。
本实施例的座体包括安装在内筒口边缘上的座体衬板12，座体衬板12上开设用于装配的座体衬板安装孔11。
进一步地，本实施例所述的门锁触发装置包括设置在活动件13上用于防止活动件 13由锁座5内脱出的限位件。
优选地，所述的限位件为设置在活动件上的限位凸起，所述活动件的一端由开口伸入锁定件内，另一端被限位凸起限制在开口外部。
作为本实施例的一种实施方式，所述的感应件16为永磁体，所述的门锁检测装置3包括可感应永磁体的磁感应元件。
优选地，所述的永磁体为磁铁，所述的磁感应元件为干簧管。
本实施例的干簧管的感应距离范围为L。
本实施例杠杆转轴14距离活动件13的距离L1，杠杆转轴14距离磁铁的距离L2。优选的是L2大于等于L1，优选的是L2大于L1。此处杠杆机构的作用是放大器，实现将锁舌17推动活动件13的距离h放大为(L2/L1)*h。举例，当锁舌17推动活动件13的距离h是5mm，(L2/L1)＝2，那么磁铁的运动量为10mm，门锁检测装置3可以更加精准的判定是否锁定到位。
如图3所示，本实施例的内筒门6锁定到位，锁舌17到位，实现锁舌17将活动件13及磁铁压向外筒壁方向，而磁铁远离外筒壁及干簧管，实现磁铁与干簧管的距离为H，所述H＞L，干簧管被断开，断路，判定门体锁定到位。
如图4所示，本实施例的内筒门6未能锁定到位或者打开，锁舌17未能到位，实现弹性件15将活动件13压向远离外筒壁方向，实现磁铁与干簧管的距离为H1，H1＝H-(L2/L1)*h，所述H1≤L或者所述H1＜L，干簧管吸合，通路，判定门体未能锁定到位。
本实施例的内筒门6上具有可转动的门把手，用于开启内筒门锁，所述的门把手通过门把手转轴4安装在内筒门6上。
本实施例的内筒门6与内筒门锁相对的一侧通过内筒门转轴机构可转动的安装在内筒的筒口上，所述的内筒门转轴机构包括转轴座8和设置在转轴座8上的转轴7，所述的转轴座8包括安装在内筒的筒口上的转轴座衬板9，转轴座衬板9上开设用于装配的转轴座衬板安装孔10。
本实施例的洗衣机内筒作为盛水筒和脱水筒，脱水时内筒会发生转动，因此为了保证设置在外筒2上的门锁检测装置3能够与内筒门锁相对进行锁定检测，本实施例的洗衣机还包括用于锁定内筒处于确定位置的内筒锁定装置，所述的门锁检测装置对应内筒处于被内筒锁定装置锁定状态下的内筒门锁的位置设置。这样，通过内筒锁定装置每次 将内筒锁定在门锁检测装置与内筒门锁相对的确定位置，以确保门锁检测装置3能够检测内筒门锁是否锁定。
为了实现向本实施例的无孔内筒内进水，本实施例的滚筒洗衣机的驱动电机通过内筒轴与内筒传动连接带动内筒转动，所述的内筒轴内具有连通内筒内部的中空通道，所述的进水管路与內筒轴的中空通道相连通。
本实施例的一种滚筒洗衣机，包括内筒1，内筒1为无孔内筒，洗涤衣物时盛放洗涤水，还包括用于连通内筒1与外界环境以平衡内筒内部气压的气压平衡机构。
进水时，内筒的密封舱内的气体受压可以通过该均平衡机构溢出，保证气压平衡。
突然断水时，外部大气可以迅速进入内筒的密封舱，并破坏倒吸，保证气压平衡，避免洗涤水被吸入自来水管网。
其他比如脱水时，该气压平衡机构也可以保证内筒气压平衡。
作为本实施例的一种实施方式，所述的气压平衡机构包括设置在内筒8上的均压孔道，所述均压孔道连通内筒1内部的一端设置在内筒1上靠近旋转中心轴位置处且始终高于内筒1内的最高水位位置。
具体地，所述的均压孔道开设在内筒轴上连通内筒1内部与外界环境，所述内筒1内的最高水位低于内筒轴。这样可以防止内筒内的水由均压孔道流出。
本实施例所述均压孔道包括第一孔道段和第二孔道段，第一孔道段与中空通道相平行设置，其一端连通内筒内部，第二孔道段的一端与第一孔道段相连通，另一端延伸至内筒轴的外周壁上与外筒的内部相通。优选地，所述的第二孔道段与第一孔道段相垂直设置形成L型的均压孔道。
本实施例提供一种内筒前开式滚筒洗衣机，内筒上设置内筒门，实现内筒封闭空间洗涤，避免内筒的衣物出来的可能，及衣物受压及摔打导致由内筒流出或者飞溅出水，避免了内、外筒之间污垢附着的可能，真正实现了滚筒的桶间无水。
本实施例的洗衣机具有内筒门锁锁定到位的门锁检测装置，确保内筒门锁定到位，确保锁定判定准确率100％，由于滚筒脱水转速会达到1600转/分钟，内筒上的内筒门如果未能锁定好，将会发生安全事故，极大的提高了机器的安全性，用户健康及用户体验。
本实施例同时提供一种所述洗衣机的控制方法，洗衣机接收洗衣指令，门锁检测装置检测内筒门锁是否锁定，若是，则执行洗衣指令，若否，则停止执行洗衣指令。
