洗涤设备及其控制方法 技术领域
本发明属于洗涤设备技术领域,具体涉及一种洗涤设备及其控制方法。
背景技术
随着科学技术的不断进步,市面上出现越来越多种类的洗涤设备,人们也开始对洗涤设备的综合性能提出越来越高的要求。以洗衣机为例,为了有效提高洗衣机的安全性能和使用体验,现有洗衣机均设置有振动检测开关。通常地,当洗衣机平稳运行时,振动检测开关都会处于闭合状态;而当洗衣机内的负载出现偏心现象时,洗衣机的洗涤桶就会产生振动现象而撞击到洗衣机的箱体上,此时,振动检测开关就会处于断开状态。现有洗衣机的控制方式是,只要振动检测开关出现断开状态就会使洗衣机停止运行;但是,经过用户反馈发现,这种控制方式在应用过程中很容易出现错判现象。例如,在洗衣机的运行过程中,如果用户不小心拍打到洗衣机的上盖,振动检测开关也会出现断开状态,从而导致洗衣机停止运行,进而严重影响用户体验。

S2:根据振动检测开关处于断开状态的持续时间,选择性地使洗衣机停止运行当前洗涤模式。
进一步地,在所述洗衣机的运行过程中,所述控制器能够控制所述洗衣机执行步骤S1,即所述控制器能够实时获取所述振动检测开关处于断开状态的持续时间;需要说明的是,本发明不对所述控制器获取所述振动检测开关处于断开状态的持续时间的方式作任何限制,技术人员可以通过使用需求自行选定获取方式;例如,所述控制器可以通过获取所述振动检测开关处于低电平的持续时间来获取所述振动检测开关处于断开状态的持续时间,或者,所述控制器也可以通过获取所述振动检测开关的两个触头之间的距离来获取所述振动检测开关处于断开状态的持续时间,即只要所述控制器能够获取到所述振动检测开关处于断开状态的持续时间即可。需要说明的是,尽管本申请中将所述振动检测开关的触发状态描述为断开状态,但这并不是对本发明的限制,本领域技术人员也可以根据需要将所述振动检测开关的触发状态描述为闭合状态,即,所述振动检测开关在常态下断开,在所述洗衣机发生大幅度振动时闭合,这种变化并不偏离本发明的基本原理,因此也将落入本发明的保护范围之内。
更进一步地,在步骤S2中,所述控制器能够根据所述振动检测开关处于断开状态的持续时间来选择性地使所述洗衣机停止运行当前洗涤模式,当然,技术人员可以自行设定使所述洗衣机停止运行当前洗涤模式的具体条件;例如,所述控制器可以将所述振动检测开关处于断开状态的持续时间与预设时间进行比较,或者所述控制器还可以将所述振动检测开关处于断开状态的持续时间与预设映射关系进行比对,以便所述控制器能够根据所述振动检测开关处于断开状态的持续时间来选择性地使所述洗衣机停止运行当前洗涤模式。本领域技术人员能够理解的是,只要所述控制方法以所述振动检测开关处于断开状态的持续时间作为其基础参数来控制所述洗衣机的当前运行状态就属于本发明的保护范围。
下面参阅图2,该图是本发明的技术方案1的控制方法的优选实施例的步骤流程图。如图2所示,基于本优选实施例中所述的洗衣机,本发明的技术方案1的控制方法的优选实施例具体包括下列步骤:
S101:获取振动检测开关处于低电平的持续时间;
S102:判断振动检测开关处于低电平的持续时间是否大于或等于预设时间;如果是,则执行步骤S104;如果否,则执行步骤S103;
S103:使洗衣机维持当前洗涤模式;
S104:使洗衣机停止执行脱水操作;
S105:使洗衣机执行进水操作;
S106:使波轮以预设转速运转第一预设时间;
S107:使波轮以第一预设转停比运转第二预设时间;
S108:使波轮以第二预设转停比运转第三预设时间;
S109:使洗衣机执行排水操作;
S110:使洗衣机继续执行脱水操作。
进一步地,在所述洗衣机的运行脱水操作的过程中,所述控制器能够控制所述洗衣机执行步骤S101,即所述控制器能够获取所述振动检测开关处于低电平的持续时间;需要说明的是,虽然本优选实施例是通过获取所述振动检测开关处于低电平的持续时间来获取所述振动检测开关处于断开状态的持续时间,但是,技术人员显然还可以通过其他方式来获取所述振动检测开关处于断开状态的持续时间,只要所述控制器能够获取到所述振动检测开关处于断开状态的持续时间即可。可以理解的是,在本优选实施例中,当所述控制器获取到所述振动检测开关处于高电平时,所述控制器就不会对所述洗衣机的运行情况进行调整;而当所述控制器获取到所述振动检测开关处于低电平时,所述控制器就会对其持续时间进行采集;当然,所述控制器也可以通过计算两次高电平之间的时间差来获取所述振动检测开关处于低电平的持续时间。需要说明的是,虽然本优选实施例是结合所述洗衣机执行脱水操作的过程为例来进行描述的,但是,本发明的控制方法显然还可以用于所述洗衣机执行其他操作的过程中,这种改变并不偏离本发明的基本原理。
进一步地,在步骤S102中,所述控制器将所述振动检测开关处于低电平的持续时间与所述预设时间进行比较,并且判断所述振动检测开关处于低电平的持续时间是否大于或等于所述预设时间。需要说明的是,所述预设时间优选为48毫秒;当然,技术人员也可以根据实际使用情况自行设定所述预设时间的长短,只要所述预设时间能够准确分辨出所述洗衣机是否真的出现持续的振动现象即可。具体而言,在步骤 S102中,如果所述控制器判断所述振动检测开关处于低电平的持续时间小于所述预设时间,则说明所述洗衣机并没有产生持续的振动现象,例如,所述洗衣机可能只是在外力作用下产生了移动现象;此时,所述洗衣机的洗涤模式无需进行调整,执行步骤S103,即所述控制器控制所述洗衣机维持当前洗涤模式。
进一步地,在步骤S102中,如果所述控制器判断所述振动检测开关处于低电平的持续时间大于或等于所述预设时间,则说明所述洗衣机已经产生持续的振动现象;此时,所述控制器必须对所述洗衣机的运行状况进行调整,以便使所述洗衣机重新进入平稳运行的状态。因此,当所述振动检测开关处于断开状态的持续时间大于或等于所述预设时间时,执行步骤S104,即所述控制器控制所述洗衣机停止运行当前洗涤模式,即,使所述洗衣机停止执行脱水操作,并且使所述洗衣机运行振动修正模式,在本优选实施例中,所述振动修正模式包括步骤S105至步骤S109。需要说明的是,虽然本优选实施例中所述的振动修正模式包括步骤S105至步骤S109;但是,这种描述显然是示例性的,即技术人员可以根据实际情况自行设定所述振动修正模式执行的具体操作。
进一步地,在步骤S105中,所述控制器控制所述洗衣机执行进水操作;优选地,所述控制器控制所述洗衣机进水至漂洗水位,当然,这并不是限制性的,技术人员也可以自行设定进水水位。接着,在步骤S106中,所述控制器控制所述洗衣机的波轮以所述预设转速运转所述第一预设时间,以便衣物能够在水中充分舒展开。需要说明的是,优选地,所述预设转速为所述波轮的洗涤转速;此外,当所述振动检测开关为晃动开关时,所述第一预设时间为2分钟;当所述振动检测开关为安全开关时,所述第一预设时间为1分钟。在步骤S107中,所述控制器控制所述洗衣机的波轮以所述第一预设转停比运转所述第二预设时间,以便衣物能够与水进行充分接触。需要说明的是,优选地,所述第一转停比为所述波轮以洗涤转速转动0.6秒,再停转0.6秒;所述第二预设时间为2分钟。在步骤S108中,所述控制器控制所述洗衣机的波轮以所述第二预设转停比运转所述第三预设时间,以便使衣物在水中尽量散开而能够均匀分布。需要说明的是,优选地,所述第二转停比为所述波轮以洗涤转速转动0.5秒,再停转0.5秒;所述第三预设时间为1分钟。本领 域技术人员能够理解的是,上述具体时间的设定均是示例性的,技术人员可以根据实际使用需求自行设定。最后,在步骤S109中,所述控制器控制所述洗衣机执行排水操作,以便所述洗衣机能够在步骤S110中继续执行脱水操作。
此外,基于上述优选实施例,所述控制方法还包括:当所述洗衣机运行振动修正模式的次数达到预设次数时,所述洗衣机还能够向用户发出异常提醒。可以理解的是,当所述洗衣机多次运行振动修正模式后,如果所述洗衣机还是产生了持续振动的现象,则说明仅依靠所述洗衣机的振动修正模式已经无法将所述洗衣机中缠绕的衣物分开;因此,所述洗衣机需要向用户发出异常提醒,甚至提示用户需要手动解开缠绕的衣物,以便用户能够准确高效地解决问题,进而最大程度地保证所述洗衣机的安全运行。本领域技术人员能够理解的是,技术人员可以根据实际使用情况自行设定所述预设次数的具体数值;优选地,所述预设次数为4次。
技术方案2:
具体而言,在本优选实施例中,所述洗衣机包括箱体、设置在所述箱体中的洗涤桶以及与所述箱体相连的盘座,其中,所述盘座上设置有晃动开关和安全开关,所述晃动开关和所述安全开关均用于检测所述洗衣机的振动情况。在所述晃动开关和所述安全开关的使用过程中,当所述洗衣机平稳运行时,所述晃动开关和所述安全开关均处于闭合状态而输出高电平;而当所述洗涤桶产生振动现象并达到各自设定的最大振动幅度时,所述晃动开关和所述安全开关则均可能转变为断开状态而输出低电平。本领域技术人员能够理解的是,虽然本优选实施例中所述的晃动开关和安全开关是设置在所述洗衣机的盘座上的;但是,所述晃动开关和所述安全开关显然还可以设置在所述洗衣机的其他位置,只要所述晃动开关和所述安全开关能够检测所述洗衣机的振动情况即可。此外,虽然本优选实施例中所述的第一振动检测开关为晃动开关,第二振动检测开关为安全开关;但是,技术人员显然还可以根据实际使用需求自行选定其他类型的振动检测开关,即本发明并不对所述第一振动检测开关和所述第二振动检测开关的具体类型作任何限制。
进一步地,所述洗衣机还包括控制器,所述控制器能够运行本发明的控制方法,即所述控制器能够通过所述晃动开关和所述安全开关获取所述洗衣机的振动情况。作为一种优选方式,所述控制器能够通过分别获取所述晃动开关和所述安全开关处于低电平和高电平的持续时间来获取所述晃动开关和所述安全开关处于断开状态和闭合状态的持续时间,并且所述控制器还能够根据所述晃动开关和所述安全开关的检测结果来控制所述洗衣机的运行。当然,这种描述并不是限制性的,所述控制器也可以通过其他方式来获取所述晃动开关和所述安全开关处于断开状态和闭合状态的持续时间;例如,所述控制器还可以通过获取晃动开关的两个触头之间的距离来获取所述晃动开关处于断开状态和闭合状态的持续时间。需要说明的是,所述控制器也可以仅获取所述晃动开关和所述安全开关处于断开状态的持续时间,而不获取所述晃动开关和所述安全开关处于闭合状态的时间。本领域技术人员能够理解的是,本发明不对所述控制器的具体结构和型号作任何限制,并且所述控制器可以是所述洗衣机原有的控制器,也可以是为执行本发明的控制方法而单独设置的控制器。
首先参阅图3,该图是本发明的技术方案2的控制方法的主要步骤流程图。如图3所示,基于本优选实施例中所述的洗衣机,本发明的技术方案2的控制方法主要包括下列步骤:

S2:获取安全开关处于断开状态的持续时间;
S3:根据晃动开关处于断开状态的持续时间和安全开关处于断开状态的持续时间,选择性地使洗衣机停止运行当前洗涤模式。
进一步地,在所述洗衣机的运行过程中,所述控制器能够控制所述洗衣机执行步骤S1和S2;在步骤S1中,所述控制器能够实时获取所述晃动开关处于断开状态的持续时间;在步骤S2中,所述控制器能够实时获取所述安全开关处于断开状态的持续时间;当然,步骤S1和S2的执行顺序是可以改变的。需要说明的是,本发明不对所述控制器获取所述晃动开关和所述安全开关处于断开状态的持续时间的方式作任何限制,技术人员可以通过使用需求自行选定获取方式;例如,所述控制器可以通过获取所述晃动开关处于低电平的持续时间来获取所述晃动开关 处于断开状态的持续时间,或者,所述控制器也可以通过获取所述晃动开关的两个触头之间的距离来获取所述晃动开关处于断开状态的持续时间,即只要所述控制器能够获取到所述晃动开关和所述安全开关处于断开状态的持续时间即可。需要说明的是,尽管本申请中将晃动开关和安全开关的触发状态描述为断开状态,但这并不是对本发明的限制,本领域技术人员也可以根据需要将所述晃动开关和所述安全开关的触发状态描述为闭合状态,即,所述晃动开关和所述安全开关在常态下断开,在所述洗衣机发生大幅度振动时闭合,这种变化并不偏离本发明的基本原理,因此也将落入本发明的保护范围之内。
更进一步地,在步骤S3中,所述控制器能够根据所述晃动开关处于断开状态的持续时间和所述安全开关处于断开状态的持续时间来选择性地使所述洗衣机停止运行当前洗涤模式,当然,技术人员可以自行设定使所述洗衣机停止运行当前洗涤模式的具体条件;例如,所述控制器可以将所述晃动开关和所述安全开关处于断开状态的持续时间分别与不同预设时间进行比较,或者所述控制器还可以将所述晃动开关和所述安全开关处于断开状态的持续时间分别与不同预设映射关系进行比对,以便所述控制器能够根据所述晃动开关和所述安全开关处于断开状态的持续时间来选择性地使所述洗衣机停止运行当前洗涤模式。本领域技术人员能够理解的是,只要所述控制方法以所述晃动开关和所述安全开关处于断开状态的持续时间作为其基础参数来控制所述洗衣机的当前运行状态就属于本发明的保护范围。
下面参阅图4,该图是本发明的技术方案2的控制方法的优选实施例的步骤流程图。如图4所示,基于本优选实施例中所述的洗衣机,本发明的技术方案2的控制方法的优选实施例具体包括下列步骤:
S101:获取晃动开关处于低电平的持续时间;
S102:获取安全开关处于低电平的持续时间;
S103:如果在第三预设时间内,晃动开关处于低电平的持续时间大于或等于第一预设时间且安全开关处于低电平的持续时间大于或等于第二预设时间,则使洗衣机停止执行脱水操作;
S104:使洗衣机执行进水操作;
S105:使波轮以预设转速运转第一预设时长;
S106:使波轮以第一预设转停比运转第二预设时长;
S107:使波轮以第二预设转停比运转第三预设时长;
S108:使洗衣机执行排水操作;
S109:使洗衣机继续执行脱水操作。
进一步地,在所述洗衣机的运行脱水操作的过程中,所述控制器能够控制所述洗衣机执行步骤S101和S102;在步骤S101中,所述控制器能够实时获取所述晃动开关处于低电平的持续时间;在步骤S102中,所述控制器能够实时获取所述安全开关处于低电平的持续时间;当然,步骤S101和步骤S102的执行顺序是可以改变的,并且步骤S101和步骤S102也可以同时执行。需要说明的是,虽然本优选实施例是通过分别获取所述晃动开关和所述安全开关处于低电平的持续时间来获取所述晃动开关和所述安全开关处于断开状态的持续时间;但是,技术人员显然还可以根据使用需求自行选定其他方式,只要所述控制器能够获取到所述晃动开关和所述安全开关处于断开状态的持续时间即可。可以理解的是,在本优选实施例中,当所述控制器获取到所述晃动开关或所述安全开关处于低电平时,所述控制器就会对其持续时间进行采集;当然,所述控制器也可以通过计算两次高电平之间的时间差来获取所述晃动开关或所述安全开关处于低电平的持续时间。还需要说明的是,虽然本优选实施例是结合所述洗衣机执行脱水操作的过程为例来进行描述的,但是,本发明的控制方法显然还可以用于所述洗衣机执行其他操作的过程中,这种改变并不偏离本发明的基本原理。
进一步地,在步骤S103中,如果在第三预设时间内,所述晃动开关处于低电平的持续时间大于或等于所述第一预设时间且所述安全开关处于低电平的持续时间大于或等于所述第二预设时间,所述控制器就会控制所述洗衣机停止运行当前洗涤模式,即,使所述洗衣机停止执行脱水操作,并且使所述洗衣机运行振动修正模式,在本优选实施例中,所述振动修正模式包括步骤S104至步骤S108。需要说明的是,虽然本优选实施例中所述的振动修正模式包括步骤S104至步骤S108;但是,这种描述显然是示例性的,即技术人员可以根据实际情况自行设定所述振动修正模式执行的具体操作。
更进一步地,作为一种优选实施例,在步骤S103中,如果所述晃动开关处于低电平的持续时间大于或等于所述第一预设时间,则所述晃动开关的计数器计数一次;如果所述安全开关处于低电平的持续时间大于或等于所述第二预设时间,则所述安全开关的计数器计数一次;如果在第三预设时间内,所述控制器判断所述晃动开关的计数器和所述安全开关的计数器的计数均大于1,则所述控制器判断所述洗衣机确实已经产生持续强烈的振动,此时,所述控制器控制所述洗衣机停止执行脱水操作,并将所述晃动开关的计数器和所述安全开关的计数器的计数均归零,以便之后再次计数。需要说明的是,如果所述控制器未在第三预设时间内检测到所述晃动开关处于低电平的持续时间大于或等于所述第一预设时间且所述安全开关处于低电平的持续时间大于或等于所述第二预设时间,则所述控制器控制所述洗衣机维持当前洗涤模式即可。本领域技术人员能够理解的是,所述第一预设时间和所述第二预设时间均优选为48毫秒,所述第三预设时间为200毫秒;当然,技术人员也可以根据实际使用情况自行设定所述第一预设时间、所述第二预设时间和所述第三预设时间的长短,只要所述控制器通过所述第一预设时间、所述第二预设时间和所述第三预设时间能够准确分辨出所述洗衣机是否真的出现持续的振动现象即可。此外,还需要说明的是,虽然本优选实施例中使用到了所述第三预设时间这个参数,但是,所述控制方法显然还可以在所述控制器检测到所述晃动开关处于低电平的持续时间大于或等于所述第一预设时间且所述安全开关处于低电平的持续时间大于或等于所述第二预设时间时就使所述洗衣机停止执行脱水操作。
进一步地,作为一种优选实施方式,在步骤S103中,如果所述晃动开关的计数器在所述安全开关的计数器之前计数,则使所述洗衣机执行第一振动修正模式;而如果所述晃动开关的计数器未在所述安全开关的计数器之前计数,则使所述洗衣机执行第二振动修正模式。当然,这只是一种优选实施方式,所述第一振动修正模式也可以和所述第二振动修正模式执行相同的操作,即所述控制器直接控制所述洗衣机执行振动修正模式即可。此外,技术人员可以根据实际使用需求自行设定所述第一振动修正模式和所述第二振动修正模式的具体操作。
进一步地,在步骤S104中,所述控制器控制所述洗衣机执行进水操作;优选地,所述控制器控制所述洗衣机进水至漂洗水位,当然,这并不是限制性的,技术人员也可以自行设定进水水位。接着,在步骤S105中,所述控制器控制所述洗衣机的波轮以所述预设转速运转所述第一预设时长,以便衣物能够在水中充分舒展开。需要说明的是,优选地,所述预设转速为所述波轮的洗涤转速;此外,当所述洗衣机运行第一振动修正模式时,所述第一预设时长为2分钟;当所述洗衣机运行第二振动修正模式时,所述第一预设时长为1分钟。在步骤S106中,所述控制器控制所述洗衣机的波轮以所述第一预设转停比运转所述第二预设时长,以便衣物能够与水进行充分接触。需要说明的是,优选地,所述第一转停比为所述波轮以洗涤转速转动0.6秒,再停转0.6秒;在所述第一振动修正模式和所述第二振动修正模式中,所述第二预设时长均优选为2分钟。在步骤S107中,所述控制器控制所述洗衣机的波轮以所述第二预设转停比运转所述第三预设时长,以便使衣物在水中尽量散开而能够均匀分布。需要说明的是,优选地,所述第二转停比为所述波轮以洗涤转速转动0.5秒,再停转0.5秒;在所述第一振动修正模式和所述第二振动修正模式中,所述第三预设时长均优选为1分钟。本领域技术人员能够理解的是,上述具体时长的设定均是示例性的,技术人员可以根据实际使用需求自行设定。最后,在步骤S108中,所述控制器控制所述洗衣机执行排水操作,以便所述洗衣机能够在步骤S109中继续执行脱水操作。
此外,基于上述优选实施例,所述控制方法还包括:当所述洗衣机运行振动修正模式的次数达到预设次数时,所述洗衣机还能够向用户发出异常提醒。可以理解的是,当所述洗衣机多次运行振动修正模式后,如果所述洗衣机还是产生了持续振动的现象,则说明仅依靠所述洗衣机的振动修正模式已经无法将所述洗衣机中缠绕的衣物分开;因此,所述洗衣机需要向用户发出异常提醒,甚至提示用户需要手动解开缠绕的衣物,以便用户能够准确高效地解决问题,进而最大程度地保证所述洗衣机的安全运行。本领域技术人员能够理解的是,技术人员可以根据实际使用情况自行设定所述预设次数的具体数值;优选地,所述预设次数为4次。
最后需要说明的是,上述实施例均是本发明的优选实施方案,并不作为对本发明保护范围的限制。本领域技术人员在实际使用本发明时,可以根据需要适当添加或删减一部分步骤,或者调换不同步骤之间的顺序。这种改变并没有超出本发明的基本原理,属于本发明的保护范围。
至此,已经结合附图描述了本发明的优选实施方案,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。
