进一步地,光感检测器包括第一光感检测器、第二光感检测器,第一光感检测器设置在定位杆完成定位运动、遮光板所处期望位置,第二光感检测器设置在定位杆完成解锁运动、遮光板所处期望位置。通过第一光感检测器可检测定位杆是否完成定位阶段的运动,第二光感检测器可对应检测定位杆是否完成解锁阶段的运动。
进一步地,光电板上设置沿定位杆运行方向延伸一定长度的限位孔,遮光板内嵌于限位孔内、对应定位杆的一截面设置、并随定位杆一并运动,第一光感检测器、第二光感检测器 分别设置在限位孔的一侧;优选的,遮光板与定位杆的移动方向、光电板照射向光感检测器的检测光的方向分别相垂直。通过限位孔的设置,使得可限定遮光板的运动方向,并且可保证遮光板在随定位杆运动的过程中可对应遮挡第一光感检测器、第二光感检测器处的光源。
进一步地,第一光感检测器、第二光感检测器均设置控制开关,所述控制开关均与为开门杆、定位杆运动供能的电机相连。由于第一光感检测器、第二光感检测器的开关均与电机相连,可控制电机在运动时开启第一光感检测器、第二光感检测器,即在定位杆移动的过程中才开启第一光棍检测器、第二光感检测器,防止浪费能源。
进一步地,光感检测装置可发射位置信号,洗衣机门锁检测模块包括接收位置信号的信号接收装置。
进一步地,机门和/或洗涤筒的定位孔处设置导轨槽,导轨槽由定位孔沿定位杆运动方向延伸,穿入定位孔的定位杆内嵌在导轨槽内移动;定位杆的底部固定滑块,导轨槽内设置可卡嵌滑块的凹槽,凹槽内设置检测凹槽内是否卡嵌滑块的检测装置。即本发明提供的门锁检测模块还可通过导轨槽、滑块、凹槽的设置实现对定位杆是否移动到位的检测。
进一步地,洗衣机门锁检测模块包括检测机门是否关闭到位的关门检测装置,关门检测装置包括设置在机门上的磁铁,外壳和/或外筒上上设置霍尔传感器,霍尔传感器用于检测磁铁的位置,霍尔传感器设于机门关闭且锁止时可对机门上所设磁铁进行检测处;优选的,在机门关闭锁止到位时,霍尔传感器可检测到机门上所设磁铁;在机门未关闭锁止到位时,霍尔传感器无法检测到机门上所设磁铁。通过磁铁和霍尔传感器的设置可实现对门锁模块是否锁止到位的检测。
进一步地,洗衣机上设置门锁装置,门锁装置包括固定在机门上的门勾、与门勾相对的位置固定锁体,机门关闭到位的动作触发锁体锁定门勾。

6)本发明提供的洗衣机机门控制方法,还合理设计了开、关机门时,内、洗衣机门需分别进行的操作,保证开、关机门的正常进行。
本发明的又一发明目的在于提供一种洗衣机门锁模块,洗衣机门锁模块中的限位块结构合理,可实现引导锁定部旋转运动的效果。
本发明提供了一种洗衣机门锁模块,包括与机门固定的门勾,锁定部旋转并勾住门勾,限位块移动至与勾住门勾的锁定部相限位抵接,限位块上设置引导斜面,锁定部触发运动后与限位块的引导斜面相接触,引导斜面引导锁定部旋转。本发明的洗衣机门锁模块中限位块的结构设计合理,可引导锁定部按照设定的轨迹旋转。
进一步地,引导斜面的具体结构为:限位块上具有类似长方形的限位柱,限位柱靠近锁定部的顶角处设置引导斜面;引导斜面为由限位柱的顶部向下逐渐外扩的斜面,引导斜面引导锁定部顺时针旋转。
进一步地,限位柱上与引导斜面相连、靠近旋转的锁定部的一侧端面为第二限位面,锁定部上与第二限位面相对的端面为第三限位面,锁定部顺时针旋转、限位块沿直线靠近锁定部移动的过程中,第二限位面、第三限位面相限位抵接。限位柱上还设置可锁止锁定部的限位面,并且所述锁止锁定部的限位面与引导斜面设置在同一限位柱上,使得限位块的结构比较简单。
进一步地,限位块上具有与限位柱相垂直的底座,限位柱与底座构成中部具有空隙的“L”形结构,静止的锁定部内嵌于空隙中,锁定部与旋转轴垂直的一端面与限位柱上相对的第一限位面相抵接;洗衣机门锁模块具有外壳,限位块设置在外壳内,限位块与锁定部的旋转轴相垂直的一侧端部与外壳之间设置压簧,静止的限位块压缩压簧。
进一步地,限位块的一端延伸至外壳的外部;优选地,限位块未设置压簧的一端延伸至外壳的外部。限位块可延伸至外壳外部,使得可通过其他外部的结构激发限位块运动,实现对机门的解锁。
进一步地,锁定部可旋转的具体结构为:外壳内固定支撑杆;支撑杆上套设锁定部,支撑杆上、锁定部的两侧分别套设扭簧。
进一步地,门勾与锁定部配合的具体结构为:门勾包括延伸至外壳内的卡勾部,卡勾部上设置供锁定部勾住的卡孔;外壳内设置供卡勾部伸入的导轨,导轨由外壳与门勾相对的顶端面向外壳内延伸;锁定部设置为开口与门勾相对的“C”型结构,锁定部的开口可与门勾的卡孔相卡住配合。

采用上述技术方案,本发明与现有技术相比具有以下有益效果:
1)本发明提供的洗衣机门锁模块中的限位块结构设计合理,使得在锁定机门的过程中,限位块可引导锁定部按照设定的轨迹旋转,保证限位块正常勾住门勾。
2)本发明提供的洗衣机门锁模块,锁定结构和限位块的结构设计合理,使得被门勾触发的锁定结构可直接带动限位块运动,进而使运动后的限位块锁止锁定结构。即门锁模块中不需要再设置其他触发限位块的结构,使内部结构简单。
3)本发明的限位块形状设计合理,限位块上还设置与锁定部相限位抵接的端面,在静止时、其上的部分端面可被锁定部限制住,以保持静止;而在运动后,勾住门勾的锁定部可与限位块上另外的端面相限位抵接。即通过一块限位块不仅可以实现引导锁定部的旋转,还可锁止锁定部。
4)本发明限位块的结构延伸至外壳的外部,使得门锁模块外部的其他结构可接触触发限位块移动,进而实现对机门的解锁。这样可通过门锁模块外部的其他结构自动触发解锁。

具体实施方式
本发明提供了一种洗衣机,洗衣机内设置洗涤衣物的洗涤筒,洗涤筒上设置洗涤筒门42。在洗涤筒的外部设置支撑外壳和/或外筒,支撑外壳和/或外筒上与洗涤筒的洗涤筒门42相对的位置设置洗衣机门43。
本发明的洗衣机中设置锁止、解锁机门的门锁系统,门锁系统包括在关闭机门后可使机门锁止的门锁模块40;包括可相应使门锁模块40解锁的定位解锁模块41,定位解锁模块41还可实现对洗涤筒锁止位置的定位。所述门锁的结构可应用在洗衣机门43和/或洗涤筒门42上。
具体地,门锁模块40可应用在洗涤筒门42上,也可应用在洗衣机门43上。门锁模块40包括与机门相固定的门勾,固定在洗涤筒上或支撑外壳上的锁定装置,在关闭机门时门勾可对应伸入锁定装置中,并被锁定装置勾住以实现对机门的锁止。比如可在洗涤筒门42上设置门勾、洗涤筒上设置锁定装置以实现对洗涤筒门42的锁止。或者可在洗衣机门43上设置门勾、支撑外壳上设置锁定装置以实现对洗衣机门43的锁止。
定位解锁模块41中具有定位杆22,定位杆22可通过穿入设置的定位孔实现对位置的定位;定位解锁模块41中还具有开门杆23,开门杆23在进行期望运动后可激发门锁模块40的门勾与锁定装置相脱离,实现对机门的解锁;即本发明提供的定位解锁模块41不仅可实现定位、还可同时实现解锁功能。为了实现对洗涤筒门42的解锁,可将定位解锁模块41设置在与洗涤筒门42上的门锁装置相对的洗涤筒上,并且将定位孔设置在洗涤筒前法兰上,这样可实现对洗涤筒、洗涤筒门42锁止位置的定位。或者为了实现对洗衣机门43的解锁,可将定位解锁模块41设置在支撑外壳上。
由上述可知,本发明提供的洗衣机的门锁系统可使洗涤筒门42、洗衣机门43分别实现单独打开或锁止,并且门锁系统还可实现对洗涤筒、机门锁止位置的定位。本发明还针对上述的门锁系统的结构提供了相应控制内、外双层机门的控制方法,本发明提供的控制方法可保证合理的控制打开或关闭双层机门。
实施例1
本实施例提供了一种锁止、解锁机门的门锁模块40,门锁模块40包括与机门相固定的门勾1,在关机门的过程中门勾1将会随机门一起运动。门锁模块40还包括对门勾1进行锁定的锁体。锁体具有外壳,当关闭机门时,门勾1随机门对应伸入锁体内并被体锁止,进而实现对机门的锁止。
其中,锁体包括可旋转运动的锁定部4,锁定部4沿某一方向旋转运动中可勾住门勾1,锁定部沿反方向运动时可与门勾1脱离接触。锁体中还包括限制锁定部4运动状态的限位块2。当门勾1被锁定部4勾住时,限位块2与锁定部4相抵接,使锁定部4保持不动,进而保证锁定部4可持续、稳定地锁住门勾1。当需要解锁时,可使限位块2发生移动时,解除对锁定部4的限位,锁定部4沿反向旋转,进而锁定结构与门勾1相分离,实现对机门的解锁。
如图1中所示,锁体包括外壳3,锁定部4可旋转地设置在外壳3中。具体地,外壳3中架设支撑杆10,支撑杆10的两端固定在锁体的外壳3上,支撑杆10上套设可旋转的锁定部4,通过支撑杆10的支撑使得锁定部4固定在外壳3内部。限位块2具有类似于“L”型的结构,在锁定装置未开始运动时,锁定部4内嵌于限位结构上“L”型结构的空隙中。“L”型结构由竖直的限位柱44和与其垂直的水平的底座组成。当限位块2内嵌在“L”型结构的空隙中时,锁定部4与旋转轴相垂直的端面5与限位柱44上相对的第一限位面6相抵接。即在运动之初时,锁定部4与限位块2相卡嵌限位。限位块2上与锁定部4的旋转轴相垂直的一侧端部与外壳3之间设置压簧,运动之初静止时、限位块2压缩压簧。即锁定部4在静止的状态时,限位块2被静止的锁定部4所限位,同时限位块2又压缩着压簧。
而当门勾1接触并触发锁定部4旋转后,锁定部4发生旋转,锁定部4解除对限位块2的运动限制,故限位块2在压簧的作用下开始运动。如图2、3中所示,限位柱44上与旋转的锁定部4相对的顶角位置设置引导斜面7。开始转动的锁定部4可与运动的限位块2上的 引导斜面7相配合接触。锁定部4在与其接触的引导斜面7的引导作用下,按照设定的轨迹旋转。
所述引导斜面7为由限位柱44的顶部向下逐渐外扩的斜面,这样的形状使得与引导斜面7相接触的锁定部4易在引导斜面7的引导作用下顺时针旋转。顺时针旋转的锁定部4易勾住门勾1,而勾住门勾1后的锁定部4会最终与限位块2相限位抵接,即锁定部4被限位块2所锁住。即引导斜面7的设置便于引导锁定部4按照设定的轨迹旋转并勾住门勾。
限位柱44与勾住门勾1的锁定部4相抵接的具体结构如图3中所示:限位柱44上具有与锁定部4的旋转轴相平行的第二限位面8,锁定部4上具有与旋转轴平行的第三限位面9。限位柱44的第二限位面8可与旋转后的锁定部4的第三限位面9相限位抵接。即限位柱44可锁住勾住门勾1的锁定部4,进而实现对机门的锁止。限位柱44上的第二限位面8与引导斜面7相连,且第二限位面8设置在靠近旋转的锁定部4的一侧。被引导斜面7引导旋转的锁定部4,将转动至与限位柱44上的第二限位面8相限位抵接,即限位块2可实现对锁定部4的锁止。而相应的,当需要解锁时,只需激发限位块2移动,第二限位面8、第三限位面9解除限位,锁定部4在扭簧11的作用下沿反方向旋转,使得锁定部4与门勾1脱离接触。
如图中所示,限位块2的部分结构设置在外壳3的外部,使得其它结构可推动限位块2。机门处于锁止状态时,限位块2上设置的压簧处于压缩蓄力的状态。当机门需要解锁时,其它结构推动限位块2位于外壳3外部的部分,限位块2在压簧的作用下产生解锁运动。进而如前所述,门勾1与锁定结构分离、机门实现解锁。具体地,限位块2上未设置压簧的一端延伸至外壳3的外部,延伸至外壳3外部的部分供其它装置激发限位块2移动。
门勾1的具体结构如图中所示,门勾1包括与机门相固定的固定部15,固定部15上可设置螺钉孔、螺栓孔,通过螺纹连接将门勾1固定在机门上。或者固定部15上还可设置卡扣等其它固定结构,将门勾1固定在机门上。本实施例以螺钉连接为例,门勾1上设置螺钉孔。在机门上设置安装门勾1的安装槽,安装槽内可内嵌门勾1的固定部15,通过螺纹连接将门勾1的固定部15固定在安装槽内。门勾1上的固定部15设置在外壳3的外部、且固定在机门上,门勾1上还包括与固定部15相连的卡勾部12。卡勾部12由与固定部15连接位置向外壳3内部延伸,卡勾部12延伸至外壳3内部的部分结构上设置卡孔13。当需要锁止机门时,门勾1随机门运动后,门勾1的卡勾部12与锁定结构相接触,卡勾部12触发锁定部4旋转,锁定部4的部分结构卡嵌在卡孔13中,即通过卡勾与锁定部4的卡嵌连接,使门勾1被锁止,进而锁止机门。门勾1需要按照预设的轨迹运动,才可保证门勾1上的卡孔13与锁定部4相卡嵌配合,进而保证锁止机门。故为了更好地限定门勾1的运行轨迹,在锁定结构的外壳3内设置供门勾1运行的导轨14。所述导轨14由外壳3与门勾1相对的顶端面向外壳3内部延伸。门勾1的卡勾部12内嵌在导轨14中,门勾1进行锁止和解锁运动时,卡勾部12都会沿导轨14设定的方向运行,进而如上所述,保证机门被正常锁止和解锁。
如图3中所示,关闭机门时门勾1伸入锁定部4内,门勾1与相对设置的锁定部4相接触,并激发锁定部4与门勾1上的卡孔13相卡嵌。锁定部4设置为开口16朝向卡孔13的“C”型结构,“C”型结构的开口16可与门勾1的卡孔13相卡嵌。锁定部4的结构受到门勾1的接触作用发生转动,在转动的过程中,门勾1的卡孔13与“C”型结构的开口16相卡嵌。并且同时,限位块2移动与“C”型结构相抵接的位置,使门勾1保持被“C”型结构卡住,进而实现对机门的锁止。具体地,如前所述,限位块2的第二限位面8与锁定部4的第三限位面9相限位抵接。其中,第三限位面9为锁定部4的“C”型结构中与开口16相对门的面。锁定结构上还需要设置扭簧11,以使解锁时锁定结构的锁定部4发生转动,进而使锁定部4的“C”型结构与门勾1相脱离。扭簧11具体套设在支撑杆10上,设置在锁定部4的与旋转轴垂直的两端面上。
本实施例提供的门锁模块40中的限位块2的结构设置合理,限位块2上包括多个可与锁定部4相接触的端面,通过这些端面的设置,可使锁定部4在静止时被限位块2限位不可旋 转,锁定部4被触发运动后被限位块2引导着按设定轨迹旋转,并且锁定部4勾住门勾1后被限位块2锁止。本实施例提供的门锁模块40的结构设置合理,使得可通过推动限位块2位于外壳3外部的部分即可实现对机门的锁止和解锁。且仅通过限位块2的移动便可实现对机门的锁止和解锁,操作比较简单。
实施例2
本实施例在实施例1的基础上提供了一种门锁模块40,门锁模块40具有如前所述的门勾1、锁定部4和限位块2,同样门勾1可与锁定部4相互卡嵌以锁止机门,限位块2用以保持门勾1与锁定部4稳定卡嵌、或者使门勾1与锁定部4脱离。本实施例的门锁模块40与实施例1中的门锁模块40的区别在于,本实施的门锁模块40中设置手动控制限位块2移动的手动开门块17,进而可实现手动控制门锁模块40对机门进行解锁。实施例1中提及可利用门锁模块40外的其他结构自动触发门锁模块40的限位块2移动,自动实现对机门的解锁。自动为机门解锁供能的装置一旦出现问题,将导致机门无法正常解锁,影响洗衣机的使用。本实施例提供的门锁模块40内部由于具有手动开门块17,在任何情况下均可手动触发解锁,保证机门均可被正常解锁使用。
如图1中所示,门锁模块40的外壳3上设置安装手动开门块17插入的安装孔。手动开门块17的顶部设置凸起的按钮20,便于向下按压手动开门块17。优选地,按钮20凸出于门锁模块40的外壳3表面,便于需要时按压按钮20。插入至外壳3内的手动开门块17与限位装置具有相互接触的端面。相互接触的端面分别为限位块2上的第一接触面18与手动开门块17上的第二接触面19,
具体如图4中所示,限位块2上设置可与嵌入的手动开门块17相接触的接触部,接触部设置在限位块2靠近手动开门块17的一侧、与手动安装块相对,接触部上设置第一接触面18,第一接触面18设置为向外凸出的曲面。手动开门块17上的第二接触面19相应地设计为由底部向上逐渐外扩的斜面。当按压按钮20后,手动开门块17向下运动。此时,由于第一接触面18和第二接触面19的形状特征,第二接触面19将会推动第一接触面18,即触发限位块2移动。限位块2尾部的压簧在机门锁定的状态时处于压缩状态,一旦限位块2被触发运动,压簧便会带动限位块2与锁定结构脱离,进而使门勾1与锁定结构脱离、完成机门的解锁。
手动安装块上还设置压簧,比如可将压簧设置在手动安装块的底部。当按压手动安装块上的按钮20进行解锁后,手动安装块将会在压簧的作用下复位。手动安装块在复位的过程中,第二接触面19和第一接触面18相配合限位,第二接触面19最终被第一接触面18所卡住,保证手动开门块17复位至预设的位置,以保证手动安装块下次可被正常使用。
本实施例提供的门锁模块40,由于锁定装置的内部设置了手动开门块17,可保证在任何情况下均可手动对机门解锁。
实施例3
本实施例提供了一种洗衣机机门的定位解锁模块41用以解锁机门、定位锁止位置,所述定位解锁模块41适用于所有洗衣机机门,尤其适用于解锁设置在洗涤筒上的洗涤筒门42。所述定位解锁模块41如图5中所示,具有开门杆23、定位杆22;定位解锁模块41的结构可使定位杆22实现对锁止位置的定位,同时可使开门杆23实现对机门的解锁。
定位解锁模块41在自然起始的状态时,定位杆22和开门杆23均在定位解锁模块41内部保持静止。在定位解锁模块41进行定位、解锁时,共可经历两个阶段的运动。第一阶段为定位阶段,定位杆22伸出至定位解锁模块41外部,并且伸入相应设置的供定位杆22定位的定位孔中,通过定位杆22穿过定位孔实现对洗涤筒的限位。所述定位孔可设置在洗涤筒门42和/或洗涤筒上,当洗衣机停止运行时,洗涤筒和洗涤筒门42将会止动在预设的位置,此时定位孔的位置与定位杆22的位置相对。控制定位杆22伸入定位孔内即可保证洗涤筒和/或洗涤筒门42锁止在预设的位置。具体地,可将定位孔设置在外筒前法兰上。一旦洗衣机停 止运行,洗涤筒门42和洗涤筒将会停止在预设的位置,此时,洗外筒前法兰上的定位孔与定位杆22相对,控制定位杆22向下运动至定位孔内即可完成对洗涤筒和/或洗涤筒门42的锁止位置的定位。
为了保证定位的准确性,还可在洗涤筒前法兰的定位孔位置设置导轨槽,定位杆22内嵌在导轨槽中便可准确限定定位杆22的运动轨迹。定位杆22上还可设置滑块,导轨槽上设置卡嵌滑块的凹槽。当定位杆22完成定位运动后,可控制滑块嵌入凹槽中。这样可通过在导轨槽和/或凹槽中设置检测装置,检测装置可检测是否完成定位,即如果成功定位,定位杆22和/或滑块应运动至导轨槽和/或凹槽的预设位置,检测装置可检测到定位杆22和/或滑块。实施例提供的定位解锁模块41不均可利用定位杆22对洗涤筒、机门锁止位置进行定位,还可通过检测装置检测是否成功完成定位。
在定位阶段,开门杆23会沿水平方向移动,移动至定位解锁模块41的外侧,即开门杆23朝向门锁模块40移动,以使开门杆23之后激发门锁模块40进行解锁。在定位阶段,定位杆22伸入定位孔、开门杆23向门锁模块40延伸一段距离,保证了之后再进行解锁运动操作时,开门杆23再继续向外伸出时肯定可以伸出至与门锁模块40相接触,激发其解锁。本实施例以开门杆23沿水平方向运动,定位杆22沿竖直方向运动为例。实际上,开门杆23和定位杆22的期望运动轨迹还可调整。本实施例的定位解锁模块41的结构可实现开门杆23与定位杆22相互垂直的运动方向,定位解锁模块41变化安装角度后还可实现开门杆23沿竖直方向运动,定位杆22沿水平方向运动。
完成定位阶段后,定位解锁模块41将进入解锁阶段。在解锁阶段,开门杆23继续沿水平方向定位解锁模块41外部移动,开门杆23接触并激发机门上的门锁模块40,使门锁模块40实现解锁。而本实施例的定位解锁模块41在运行中先经过定位阶段、再经过解锁阶段,保证洗涤筒、机门被锁止在预设的位置后才进行解锁,保证了机门在解锁的过程中洗涤筒、机门锁止在预设的位置。并且在对机门进行锁止运动时,还可利用本实施例的定位解锁模块41中的定位杆22等结构,保证洗涤筒、机门锁止在预设的位置。即本实施例提供的定位解锁模块41可使洗衣机实现在开、关机门的过程中洗涤筒均锁止在预设的位置。
如图6中所示,定位解锁模块41包括为定位阶段运动提供动力的第一驱动系统。第一驱动系统包括电机24,电机24包括输出旋转运动的输出轴,输出轴上套设输出齿轮25、输出齿轮25又与第一齿轮35相啮合连接,第一齿轮模块26主要用以减速并传递旋转运动,第一齿轮模块26为减速齿轮组。第一齿轮模块26包括齿数较多的第一齿轮35和齿数较小的第二齿轮36,第一齿轮35与第二齿轮36同轴设置。输出齿轮25与齿数较多的第一齿轮35相啮合连接,第一齿轮35转动又可带动第二齿轮36转动。即通过输出齿轮25与第一齿轮35模块26的连接,使得电机24输出的旋转运动减速。
第一齿轮模块26啮合连接第二齿轮模块27,具体地,第一齿轮模块26的第二齿轮36与第二齿轮模块27啮合连接。第二齿轮模块27分别为带动开门杆23和定位杆22的期望运动提供动力,即第二齿轮模块27带动定位杆22向下运动,同时通过第三齿轮模块31带动开门杆23向外移动一段距离。第二齿轮模块27由于同时为定位杆22和开门杆23提供动力,故第二齿轮模块27需要承受较大的力,故需要增强第二齿轮模块27的强度,具体地,可如图中所示,在第二齿轮模块27上设置加强筋。
这里需要指出的是,设置第三齿轮模块31的目的是:使得开门杆23在解锁阶段便向外伸出一定距离,这样当解锁阶段、定位杆22继续带动开门杆22再向外伸出时,保证开门杆23向外伸出的总长度,开门杆23必定可接触门锁模块触发解锁。第一齿轮模块26、第二齿轮模块27、第三齿轮模块31均是旋转轴固定的定齿轮。
如图6中所示,定位解锁模块41中还包括运行块28,运行块28内嵌定位杆22,定位杆22可与运行块28共同运动。运行块28上与第二齿轮模块27相对的位置设置第二齿条29,第二齿条29与第二齿轮模块27相啮合连接。这样第二齿轮模块27可带动第二齿条29运动, 进而带动运行块28和定位杆22运动,最终使得定位杆22实现定位运动。即第二齿轮模块27通过与第二齿条29相连,实现为定位杆22的在定位阶段的运动提供动力。
定位解锁模块41具有壳体21,且第一齿轮模块26、第二齿轮模块27、第三齿轮模块31均设置在壳体21内,定位杆22和开门杆23均可收缩在壳体21内,这样将会造成壳体21内具有较多的结构,为了节省壳体21的空间、并且防止设置在壳体21内的各部分结构相互干扰,需要在壳体21内合理地布置空间。具体地,第二齿轮模块27的旋转轴与电机24的旋转轴相平行设置,第二齿轮模块27具有经过旋转轴的竖直中心面,第一齿轮模块26、第三齿轮模块31设置于相对于所述竖直中心面的同一侧,定位杆22设置于相对于所述竖直中心面的另外一侧。将定位杆22与第三齿轮模块31分别设置在第二齿轮模块27所述的两侧,可使得定位杆22与开门杆23的运动相互之间不会干扰。并且由于第一齿轮模块26、第二齿轮模块27、第三齿轮模块31是依次连接的,即第一齿轮模块26与第三齿轮模块31之间必定存在高度差,故可将第一齿轮模块26与第三齿轮模块31设置在同一侧。
由上述结构可知,在定位阶段,定位解锁模块41可同时控制开门杆23、定位杆22进行运动,电机24首先带动第一齿轮模块26进行减速旋转,之后第一齿轮模块26带动第二齿轮模块27旋转,旋转的第二齿轮模块27分别带动第三齿条30旋转、第三齿轮模块31旋转,进而同时带动定位杆22向下运动、开门杆23沿水平方向向定位解锁模块41外部移动。
如图6中所示,在解锁阶段,开门杆23将继续沿水平方向向定位解锁模块41的外部移动以实现对机门的解锁。为实现解锁阶段的运动,定位解锁模块41设置可推动开门杆23进一步向外移动的第四齿轮模块33。第四齿轮模块33同样为旋转轴固定的定齿轮,第四齿轮模块33设置在开门杆23的第三齿条30之上,并且第四齿轮模块33与开门杆23的第三齿条30始终保持接触,一旦第四齿轮模块33开始旋转则第四齿轮模块33上的第一啮合面与第三齿条30相啮合连接。运行块28上与第四齿轮模块33相对的面上设置第一齿条32,并且所述第一齿条32在定位阶段中将会随运行块28不断下降,定位阶段完成时运行块28及其上的第一齿条32将会移动至预设的位置,第四齿轮模块33设置在可与位于所述预设位置的第一齿条32相啮合连接的位置,即运行块28的第一齿条32到达与第四齿轮模块33相啮合的位置时将会带动第四齿轮模块33转动,进而使第四齿轮模块33推动开门杆23进行解锁运动。开门杆23再次向定位解锁模块41的外部伸出并触发门锁模块40,使得门锁模块40完成解锁动作。其中,第四齿轮模块33的旋转轴、第三齿轮模块31的旋转轴与开门杆23的垂直距离相等。这样设置,可使开门杆23上受到的力较均匀,保证开门杆23沿水平方向运动。
如图6中所示,可在运行块28上设置长方形凸起34,凸起34与第二齿轮模块27相对的侧面上设置第二齿条29,凸起34与设置第二齿条29的侧面相平行的另一侧面设置第一齿条32。这样通过设置一块运行块28,便可实现定位杆22被第二齿轮模块27带动、定位杆22又带动第四齿轮模块33的运动,比较节省壳体21内的空间。
如图6中所示,第一齿条32、第二齿条29的底端面均与运行块28的底端面齐平设置,这样使凸起34的形状比较简单。其中,由于定位杆22在定位阶段、解锁运动的全程中均需要被第二齿条29带动向下伸出,故第二齿条29的长度应满足使定位杆22完成定位阶段、解锁阶段的全部运动,即第二齿条29的长度大于等于定位杆22在定位阶段、解锁阶段向外伸出的总长度。而为了节省齿条的长度,第二齿条29的长度等于定位杆22在定位阶段运动、解锁阶段运动中向外伸出的总长度,如图6中所示,L5为定位杆22在定位阶段需向下伸出的长度,L4为定位杆22在解锁阶段需要向下伸出的长度,即第二齿条29的长度=L4+L5。由于第一齿条32在解锁阶段带动开门杆23运动,第二齿条32的长度应满足开门杆23完成在解锁阶段的运动,故第一齿条32的长度大于或等于开门杆23在解锁阶段向外伸出的长度。优选地,第二齿条29的长度>第一齿条32的长度。
并且如图6中所示,第四齿轮模块33、第三齿轮模块31均带动开门杆23上的第三齿条 30运动。设第四齿轮模块33的旋转轴与第三齿轮模块31的旋转轴的水平距离为L1,假设第三齿条30由与第三齿轮模块31相接触的位置开始向左伸出,如果L1大于开门杆23在定位阶段、解锁阶段中向外伸出的总长度,则第三齿条30可能无法与第四齿轮模块33相啮合接触,故L1小于开门杆23在定位阶段、解锁阶段中向外伸出的总长度。
并且当齿轮均正常啮合时,定位杆22的第二齿条29与第二齿轮模块27在旋转轴所处位置开始啮合,定位杆22的第一齿条32与第四齿轮模块33在其旋转轴所处的位置开始啮合。设第二齿轮模块27的旋转轴与第四齿轮模块33的旋转轴之间的竖直距离为L2,L2的长度应大于等于定位杆22在定位阶段中向外伸出的长度,以保证定位杆22完成定位阶段的运动。故为了节省定位解锁模块壳体内部的空间,优选的,L2的长度等于定位杆22在定位阶段中向外伸出的长度。
本实施例提供的定位解锁模块41中包括开门杆23和定位杆22,定位解锁模块41内部的结构使得定位杆22可进行对洗涤筒的锁止位置进行定位,并且同时使开门杆23实现对机门的解锁。并且通过本实施例定位解锁模块41的结构,可使伸入定位孔内的定位杆22带动开门杆23进行解锁运动,保证洗涤筒和/或机门锁定在预设的位置时才进行解锁。
实施例4
本实施例在上述实施例的基础上提供了一种洗衣机门锁检测模块,本实施例提供的洗衣机门锁检测模块可用以检测机门门锁的状态。所述门锁中可包括实施例1、实施例2中提及的门锁模块40,实施例3中提及的定位解锁模块41。洗衣机门锁检测模块中至少包括激发门锁解锁的开门杆23、对门锁和/或洗涤筒位置定位的定位杆22;其中,开门杆23、定位杆22可相互联动。洗衣机门锁检测模块还包括对定位杆22检测、判断门锁状态的检测装置。由于开门杆23、定位杆22相互联动,具体如实施例3中所述,定位杆22在实现对洗涤筒和/或机门的定位后,定位杆22带动开门杆23运动。故开门杆23未对机门进行解锁、或者开门杆23已经对机门完成解锁时,定位杆22也相应的具有不同的运动状态和/或运动至不同的位置,故可通过检测装置对定位杆22进行检测以判断门锁的运动状态。
实际对机门进行解锁的过程中,开门杆23需要接触并触发如实施例1、2中所述的门锁模块40,开门杆23与门锁模块40之间不便于设置检测装置,这样将导致对开门杆23进行检测比较困难。而当开门杆23具有相互联动的定位杆22时,比如实施例3中所提供的定位解锁模块41;便可如上所述,通过检测定位杆22的运动以检测门锁是否被解锁。
开门杆23、定位杆22在完成解锁定位的过程中可能需要经历不同的运动阶段,不同阶段分别对应门锁的不同状态;故可通过检测定位杆22所处的运动阶段、判断门锁状态。比如实施例3中所述的定位解锁模块41,定位解锁模块41可控制定位杆22、开门杆23进行定位阶段和解锁阶段的运动。在定位阶段,定位杆22穿入定位孔内以实现定位,相应地,开门杆23向定位解锁装置外伸出。当定位杆22、开门杆23完成定位阶段的运动时,门锁处于锁止状态、且洗涤筒和机门处于被锁止在预设位置的状态。当开门杆23、定位杆22完成解锁阶段时,门锁处于解锁状态、且洗涤筒和机门依然处于被锁止在预设位置的状态。而定位杆22在定位阶段、解锁阶段中的位置时刻变化,故检测装置检测定位杆22的位置可判断出定位杆22所处的运动阶段、进而判断出机门、门锁的上述状态。定位解锁模块41也可为不同于实施例3中的定位解锁模块41,只要开门杆23与定位杆22联动,且定位杆22在不同运动阶段时位置不同,便可据定位杆22的位置判断门锁和/或机门的状态。
而为了更好地检测定位杆22的位置,优选地,定位杆22在定位阶段、解锁阶段均沿同一直线轨迹运动,检测装置设置可检测定位杆22沿直线轨迹的运动位置。定位杆22沿直线轨迹运动,使得定位杆22的运动轨迹比较简单,便于对定位杆22运动位置的追踪,则便于检测装置的位置设置。比如实施例3中提供的定位解锁模块41便可实现定位杆22在定位阶段、解锁阶段均沿同一直线轨迹运动;检测装置只需设置在定位杆22的直线运动轨迹上。
所述检测装置可为图像采集装置、电信号检测装置,本实施例中以光感检测装置为例进 行说明。如图7中所示,定位杆22上设置遮光板37,在定位杆22的直线运动轨迹处布置光感检测装置。定位解锁模块41的壳体21内、与定位杆22直线轨迹相对的位置设置可发光的光电板38。定位杆22上固定遮光板37,定位杆22将会带动遮光板37运动,定位杆22运动到不同位置时、遮光板37将会遮住不同位置的光,而通过光感检测装置检测不同的遮光位置,便可对定位杆22的位置进行定位。具体的,光电板38的部分光源与光感检测装置设置在相对于遮光板37的两侧,这样光电板38发出射向光感检测装置的部分光必定会被遮光板37所遮挡。
如图7中所示,遮光板37设置在定位杆22上固定的运行块28上。还可如图7中所示,在光电板38上设置导孔39,遮光板37可对应插入导孔39中并沿导孔39限定的方向运行,这样可限定遮光板37的运行;而光感检测装置沿导孔39设置,这样可保证光感检测装置检测到光线被遮挡。
具体地,光感检测装置包括第一光感检测器、第二光感检测器,第一光感检测器设置在定位杆22完成定位阶段运动、遮光板37所处期望位置,第二光感检测器设置在定位杆22完成解锁阶段运动、遮光板37所处期望位置。第一光感检测器、第二光感检测器均设置在光电板38上。这样当第一光感检测器检测到光线被遮挡,对应定位杆22完成定位阶段的运动;当第二光感检测器检测到光线遮挡时,对应定位杆22完成解锁阶段的运动。其中,第一光感检测器、第二光感检测器可由对光线敏感的检测器组成。
进一步优选地,第一光感检测器、第二光感检测器还可均设置控制开关,所述控制开关均与为开门杆23、定位杆22运动供能的电机24相连。这样可使电机24开始工作时才控制第一光感检测器、第二光感检测器工作,达到减少能源消耗、延长光感检测器寿命的效果。并且所有的光感检测装置可发射位置信号,洗衣机门锁检测模块还包括接收位置信号的信号接收装置。洗衣机门锁检测模块便可根据光感检测装置所发出的位置信号判定门锁的状态。
本实施例提供了一种检测定位杆22是否锁止到位的方案。洗涤筒上设置供定位杆22穿入的定位孔,定位孔所处位置设置导轨槽,穿入定位孔的定位杆22内嵌在导轨槽内移动。定位杆22的底部固定滑块,导轨槽内设置可卡嵌滑块的凹槽,凹槽内设检测装置,检测装置可对应检测凹槽内是否卡嵌滑块。当定位杆22完成定位阶段、解锁阶段的全部运动后,定位杆22上的滑块将会内嵌在所述凹槽中,故可利用设置在凹槽中的检测装置检测定位杆22的定位运动是否定位到位。
本实施例还提供了检测机门是否锁止到位的锁止检测装置,所述锁止检测装置包括设置在机门上的磁铁,洗涤筒上对应位置设置霍尔传感器;霍尔传感器检测磁铁的位置。当机门锁止到位时,机门上的磁铁应到达预设的位置,而霍尔传感器应相应地检测到磁铁,进而确定机门锁止到位。
由于洗涤筒门42需要同洗涤筒共同转动,洗涤筒门42上无法通过电信号控制控制机门自动关闭,洗涤筒门42上可设置如实施例1、2中所述的门锁装置,使洗涤筒门42通过关门的动作实现锁止。故在手动关闭锁止洗涤筒门42时,可能出现机门未被锁止到位的情况。此时便可通过上述的磁铁、霍尔传感器检测机门是否锁止到位。
实施例1、2中所述的门锁装置,具有如前所述的门勾1、锁定部4,当锁定部4未锁止时,可旋转的锁定部4将会对门勾1产生力的作用,进而与门勾1固定连接的机门将在门勾1的带动作用下无法停留在锁止的位置,相应的磁铁未到位预设的位置,霍尔传感器也无法检测到磁铁。
本实施例提供的门锁检测模块,可通过检测定位杆22的位置,准确的判断门锁的状态,且门锁检测模块中还包括检测机门是否准确被锁止的锁止检测装置。即本实施例提供的门锁检测模块可对机门锁止过程、解锁过程、定位过程进行全面的检测。
实施例5
本实施例在上述实施例的基础上提供一种洗衣机。所述洗衣机包括如实施例3中所述的 定位解锁模块41、如实施例1或者实施例2中所述的门锁模块40。如图7中所示,定位解锁模块41设置在与门锁模块40相对的位置,定位解锁模块41与门锁模块40相接触配合以完成对机门解锁。具体的,定位解锁模块41的开门杆23与门锁模块40延伸至外壳3外部的限位块2相对,开门杆23在自动进行解锁阶段的运动时激发带动限位块2进行解锁运动、完成对机门的解锁。
需要指出的是,定位解锁模块41中开门杆23的安装位置、结构可进行调整,使开门杆23的移动方向调整。如图中所示,本实施例的开门杆23的运动方向与限位块2的轴向一致,即开门杆23沿限位块2的轴向推动激发限位块2。定位解锁模块41还可调整为开门杆23沿与限位块2的轴向相垂直的方向移动,即开门杆23从限位块2的侧面推动激发限位块2,其他结构保持不变,同样可使机门实现解锁。
如图8中所示,洗衣机中具有洗涤筒,洗涤筒上设置洗涤筒门42,洗涤筒门42需要随洗涤筒一起转动,故如前所述,洗涤筒门42无法通过电信号控制自动关闭机门。故可在洗涤筒门42上设置如实施例1、2中所述的门锁模块40,使得通过关闭洗涤筒门42的动作可实现对洗涤筒门42的锁止。相应的,定位解锁模块41可固定在外筒和/或洗衣机壳上与门锁模块40相对的位置。
洗衣机中,外筒在机门的位置往往需要设置外筒前法兰,门锁模块40固定在洗涤筒门42上,定位解锁模块41固定在外筒上,则为使开门杆23可与限位块2相接触,开门杆23必须穿过外筒前法兰。故在外筒前法兰上设置供开门杆23穿过的解锁孔,由于外筒前法兰处可能接触水,故为了保证密封性,优选地在解锁孔处设置密封件。
本实施例提供的洗衣机还包括如实施例5中所述的洗衣机门锁检测模块,门锁检测模块可检测门锁模块40对机门的锁定情况,还可检测定位解锁模块41对机门的解锁、定位情况。
实施例6
本实施例在上述实施例的基础上提供了一种洗衣机控制方法,其中洗涤筒门42设置在洗涤筒上、洗涤过程中同洗涤筒共同转动;并且洗涤筒门42上设置如实施例1、2中所述的门锁模块40。洗涤筒上对应设置洗涤筒门42,洗衣机的外筒和/或外壳上对应洗涤筒门42的位置设置洗衣机门43,洗涤筒门42、洗衣机门43均可单独开、闭。本实施例尤其适用于内部仅含有单一洗涤筒的洗衣机。本实施例提供的洗衣机控制方法,合理设定开、关机门时洗涤筒门42和洗衣机门43需执行的操作,保证开、关双层机门的正常操作。
当需要打开和关闭洗衣机的双层机门时,应保证洗衣机处于停止运行、被锁止的状态,以避免洗衣机在运行过程中打开机门造成衣物、液体流出,或者在洗衣机关闭机门时进入运行状态发生危险。故本实施例的控制方法包括在打开和关闭双层机门前先检测洗衣机是否停止运行。当洗衣机停止运行时,洗涤筒应被锁止。并且在进行完打开、关闭机门的操作后,洗衣机需要进行下面的其它程序,如进行洗涤程序,洗涤筒应当由设定的锁定位置开始进行接下来的操作,故同时应当检测洗涤筒是否锁止在预设的锁定位置。洗涤筒是否锁止可由设置在洗涤筒上的检测装置检测。
具体地,需要打开洗涤筒门时,控制定位解锁模块40将洗涤筒锁止在设定位置,即控制定位解锁模块40中的定位杆22完成如实施例3中所述的定位阶段的运动,而后允许进行打开洗涤筒门的操作。
在定位解锁模块40将洗涤筒锁止在设定的位置后,门锁检测模块检测定位解锁模块40是否完成将洗涤筒锁止在设定位置,具体地,门锁检测模块如实施例4中所述,检测定位杆22的位置,判断定位杆22是否伸入定位孔内以完成将洗涤筒锁止在预设的位置。
确定洗涤筒锁止在设定位置后,控制定位解锁模块41对门锁模块40进行解锁,门锁检测模块检测定位解锁模块41完成解锁后允许打开洗涤筒门。具体地,当定位解锁模块41对门锁模块40进行解锁时,控制定位解锁模块41中的定位杆22完成如实施例3中所述的解锁阶段的运动。而当门锁检测模块检测是否解锁时,如实施例4中所述,门锁检测模块通过检 测定位杆22的位置判断是否完成解锁。
打开洗涤筒门、放入衣物后,需要关闭洗涤筒门时,控制门锁检测模块检测定位解锁模块41是否仍保持将洗涤筒锁定在设定的位置,确定定位解锁模块41仍保持将洗涤筒锁止在设定的位置后,允许进行关闭洗涤筒门操作。同样此时,需要门锁检测模块检测定位杆22的具体位置,判断定位杆22是否保持伸入在定位孔内,进而判断洗涤筒是否保持被锁止在预设的位置。
关闭机门时、控制门锁模块40对洗涤筒门进行锁定,门锁检测模块检测洗涤筒门是否被锁定,具体地,门锁模块40如实施例1、2中所述,可通过关门的动作实现对洗涤筒门的锁定。门锁检测模块可利用如实施例4中所述的锁止检测装置实现对洗涤筒门是否锁止的检测。
确认洗涤筒门被锁定后,控制定位解锁模块41解除对洗涤筒锁止在设定位置的限制;具体如实施例3中所述定位解锁模块41中电机24反转、带动定位杆22伸出定位孔内、解除对洗涤筒的锁止限制。而后控制门锁检测模块检测定位解锁模块41是否解除对洗涤筒锁止在设定位置的限制。具体,门锁检测模块对定位杆22的位置进行检测,确定定位杆22伸出定位孔时判断接触对洗涤筒锁止在设定位置的限制。确认解除对洗涤筒锁止在设定位置的限制后允许洗衣机运行,这样洗涤筒可转动实现之后的操作。
洗衣机中一般具有位于内层的、洗涤筒上的洗涤筒门42,还具有位于外层、洗衣机外筒和/或外壳上设置的洗衣机门43。在实际开机门的过程中,均是依次打开洗衣机门43、洗涤筒门42,而在进行打开洗衣机门43的操作时可先控制洗涤筒门42保持锁止,这样避免在打开洗衣机门43的过程中、洗涤筒门42发生移动而导致内、外双层机门碰撞。在实际进行开门操作时,先控制洗涤筒门42锁止,检测洗涤筒门42成功锁止后,控制洗衣机门43解锁,可进行打开洗衣机门43的操作。之后在洗衣机门43被打开后、需要打开洗涤筒门42时才控制洗涤筒门42解锁,而后方可打开洗涤筒门42。具体的控制方法为:检测到洗衣机门43被打开后,控制洗涤筒门42解锁。
由上述的实施例中可知,由于洗涤筒门42上可设置上述门锁模块40、定位解锁模块41,故洗涤筒门42可在洗涤筒锁止在预设位置的情况下、进行锁定和解锁的操作;即洗涤筒门42可实现在洗衣机门43打开的过程中保持锁止,在洗衣机门43打开之后才解锁。
具体如图10中所示,打开机门的操作包括以下步骤:
步骤S1,检测洗涤筒是否锁止且锁止在预设的位置,洗涤筒未锁止且锁止在预设的位置则执行步骤S2,洗涤筒锁止且锁止在预设位置则执行步骤S3;
步骤S2,控制洗涤筒锁止且锁止在预设的位置并执行步骤S3;
步骤S3,控制洗涤筒门42锁止,检测洗涤筒门42成功锁止后执行步骤S4;
步骤S4,控制洗衣机门43解锁并执行步骤S5;
步骤S5,检测洗衣机门43是否被打开,洗衣机门43未被打开时执行步骤S6,洗衣机门43被打开时执行步骤S7;
步骤S6,打开洗衣机门43,并执行步骤S7;
步骤S7,控制洗涤筒门42解锁,并打开洗涤筒门42。
一般进行打开双层机门的操作均是为了取出洗衣机内的衣物,而在取出衣物后往往就结束了对洗衣机的使用。直到再次向洗衣机内放入衣物并关闭机门后,洗衣机才需要被使用。在洗衣机不被使用的这段时间内,应保证洗涤筒锁止且锁止在预设的锁定位置,进而保证当洗衣机需要再次运行时,洗涤筒可从预设的锁定位置开始运行,便于洗衣机的洗涤程序正常运行。即完成打开双层机门的操作后至进行关闭双层机门操作前,洗涤筒均保持锁止且锁止在预设的锁定位置。
在进行关闭机门的操作时,依次关闭洗涤筒门42、洗衣机门43,关闭洗涤筒门42后应对洗涤筒门42进行锁止,并检测洗涤筒门42是否锁止在预设的位置。由上述实施例中洗涤 筒门42上设置的门锁模块40可知,一旦洗涤筒门42被正确地关闭后,洗涤筒门42就可被门锁模块40锁止。并且通过之前所述在洗涤筒门42上设置的磁铁还可检测洗涤筒门42是否在正确的位置被关闭、锁止。即上述控制方法,可通过检测洗涤筒门42是否锁止在预设的位置,保证在关闭洗涤筒门42时、洗涤筒门42被正确地关闭。本实施例提供的控制方法设置合理,在洗涤筒门42被关闭后进行锁止,可保证之后在进行关闭洗衣机门43的操作时,不会对洗涤筒门42造成影响。且在确认洗涤筒门42被锁止在预设的锁定位置后才可对洗衣机门43进行关闭操作,保证在准确地关闭洗涤筒门42后才关闭洗衣机门43。在关闭洗衣机门43后再对洗衣机门43进行锁止,这样的程序,可避免关闭机门时、若洗涤筒门42未被正确锁止,而出现反复关闭机门的情况。
洗衣机的内、外双层机门均被正确关闭且锁止后,洗衣机可以开始进行后续的洗涤等其它操作。而洗衣机在进行后续操作时洗涤筒需要进行期望运动,故需要对洗涤筒进行解锁的操作。并且内、外双层机门在关闭后应保持锁止的状态,防止洗衣机在运行过程内、洗衣机门43出现被打开的情况而对洗衣机的正常运行造成影响。由上述实施例中对定位解锁模块41的描述可知,可利用定位解锁模块41实现对洗涤筒的锁止和解锁,即可实现本控制方法中提及的对洗涤筒解锁、洗涤筒门42的锁止。
具体如图11中所示,关闭机门的操作包括以下步骤:
步骤S1,检测洗涤筒是否锁止且锁止在预设的位置,洗涤筒未锁止且锁止在预设的位置则执行步骤S2,洗涤筒锁止且锁止在预设位置则执行步骤S3;
步骤S2,控制洗涤筒锁止且锁止在预设的位置并执行步骤S3;
步骤S3,关闭并锁止洗涤筒门42,检测洗涤筒门42是否锁止在预设的锁定位置,未锁止在预设的锁定位置则执行步骤S4,锁止在预设的锁定位置则执行步骤S5;
步骤S4,控制洗涤筒门42锁止在预设的锁定位置并执行步骤S5;
步骤S5,关闭并锁止洗衣机门43,检测洗衣机门43是否成功锁止,洗衣机门43成功锁止后则执行步骤S6;
步骤S6,控制洗涤筒解锁。
