Description

衣物处理设备的控制方法、装置和衣物处理设备
本公开要求于2024年3月29日提交中国专利局、申请号为202410379609.8、发明名称为“衣物处理设备的控制方法、装置和衣物处理设备”的中国专利申请的优先权,其全部内容通过引用结合在本公开中。
技术领域
本公开涉及衣物处理设备技术领域,尤其涉及一种衣物处理设备的控制方法、装置和衣物处理设备。
背景技术
衣物处理设备在执行对织物的烘干操作时,如果控制烘干滚筒长时间单向转动,持续周向力作用会使得位于烘干滚筒内的需烘干负载呈现沿烘干滚筒周向延伸的长条状,同时在烘干滚筒提勒筋产生的侧向力作用下,呈现长条状的需烘干负载自身卷绕的同时也会相互缠绕。需烘干负载的相互缠绕会造成其无法在烘干滚筒内充分的铺展。由于无法充分铺展而造成需烘干负载与烘干气流的热交换比表面积减小,衣物处理设备对需烘干负载的烘干效率严重下降。
为避免前述问题,相关技术中的衣物处理设备会控制烘干滚筒交替地执行正反转,通过正反转产生的相反作用力交替地施加于需烘干负载,避免需烘干负载之间过缠绕。但是,由于相关技术中的衣物处理设备采用单电机一并驱动烘干滚筒和风扇转动,在实现烘干滚筒的交替正反转的同时,风扇也会交替的正反转。而现有衣物处理设备的风扇均为离心风机,由于离心风扇结构和蜗壳结构等原因,在其反向转动时(此处定义反向为风扇的在两个方向转动中产生较小气流的方向),风扇无法使得气流高速转动,造成在反向转动过程中需烘干负载与烘干气流的热交换效率下降。此外,因为烘干气流流速下降,衣物处理设备中的制热装置热散热效率严重下降,其会快速升温至阈值温 度而启动过热保护。

(二)技术方案
为了解决上述技术问题,本公开提供了一种衣物处理设备的控制方法、装置以及衣物处理设备,避免需烘干负载过度缠绕的同时,还可以始终保持风扇转动速率,进而保证烘干气流与需烘干负载的热交换速率。

为解决现有衣物处理设备采用单电机驱动烘干滚筒和风扇,需要周期性地控制单电机正反转避免需烘干负载过缠绕,但是会使得风扇转速降低,继而使得烘干气流单位时间流量减低并降低烘干效率的问题,本公开实施例提供一种新的衣物处理设备的控制方法。
以下首先对本公开实施例提供的衣物处理设备的结构做分析,再对基于前述结构的衣物处理设备的控制方法做分析。
与现有技术中的衣物处理设备的整体结构类似,本公开实施例提供的衣物处理设备包括制热装置、烘干滚筒和风扇。其中制热装置和烘干滚筒之间形成气流通道。风扇设置在气流通道内,风扇转动时可 以驱动气流通道内的气流流动,形成流动气流。
与现有技术不同的是,本公开实施例中的衣物处理设备中,采用两个不同的动力源分别驱动烘干滚筒和风扇转动。也就是,烘干滚筒和风扇的转动是独立的。
本公开实施例中,衣物处理设备包括一个双转子电机。双转子电机中的第一转子和第二转子可以独立的转动,第一转子驱动烘干滚筒转动,第二转子驱动风扇转动。
与现有技术不同的是,本公开实施例中的衣物处理设备中,采用两个不同的动力源分别驱动烘干滚筒和风扇转动。也就是,烘干滚筒和风扇的转动是独立的。后续在对本方案控制方法做分析时,再对本公开实施例中衣物处理设备烘干滚筒和风扇采用两个动力源的原因做分析。
本公开实施例中,衣物处理设备包括一个双转子电机。双转子电机中的第一转子和第二转子可以独立的转动,第一转子驱动烘干滚筒转动,第二转子驱动风扇转动。
图1是本公开部分应用公开的衣物处理设备部分部件的结构示意图,图2是双转子电机和部分输出传动机构的结构示意图,图3是图2中结构的爆炸示意图。图1-图3展示了双转子电机100中的两个转子通过传动轴分别独立驱动烘干滚筒5100和风扇5200转动的结构。
如图所示,本公开实施例中的双转子电机100包括定子1300,第一转子1100、第二转子1200、第一传动轴2000和第二传动轴4100。第一传动轴2100与第二转子1200刚性连接,其包括设置在双转子电机100内的第一轴部2100和设置在双转子电机外的第二轴部2200。第二传动轴4100与第一转子1100刚性连接;如图3所示,本公开实施例中第二传统轴4100通过螺钉与设置在第二转子1200上的法兰盘固定连接。
在第二传动轴4100上安装有第一皮带轮4120,第一皮带轮4120通过第一传动皮带4400带动第二皮带轮4200转动,第二皮带轮4200通过第二传动皮带4300带动烘干滚筒5100转动。在第一转子1100转动时,其通过第二传动轴4100、第一皮带轮4120、第一传动皮带4400、 第二皮带轮4200和第二传动皮带4300驱动烘干滚筒5100转动,使得烘干滚筒5100按照对应的转速转动。
烘干滚筒5100与第一转子1100的传动比根据第一皮带轮4120和第二皮带轮4200中安装第二传动皮带4300部分的半径之比,以及第二皮带轮4200中带动第一传动皮带4300转动部分和烘干滚筒的半径之比确定。假设烘干滚筒5100和第一转子1100的传动比为1:50,第一转子的转速为2500rpm,则烘干滚筒5100的转速为50rpm。
此外,第二传动轴4100上设置有第一凸台部4110和第二凸台部(位于第一皮带轮远离第一转子1100的一侧),第一凸台部4110和第二凸台部实现第一传动皮带4400的轴向定位。
如图所示,第一轴部2100和第二轴部2200通过花键连接,第二轴部2200直接与风扇5200刚性连接。在第二转子1200转动时,其通过第二轴部2100和第二轴部2200带动风扇5200同速转动。
本公开实施例中的双转子电机还包括第一支撑轮3100、第二支撑轮3200。第一支撑轮3100套设在第一轴部2100上,第一支撑轮3100和第一轴部2100之间设置有轴承4130.第二支撑轮3200套设在第二轴部上,第二支撑轮3200和第二轴部2200之间也设置有轴承。第一支撑轮3100、第二支撑轮3200配合将双转子电机100定位在衣物处理设备的底座上。
继续参见各个附图,本公开实施例,在双转子电机的外壳上设置有加强部1310,加强部1310中设置有位置可移动但被限位设定的移动轴4210,第一皮带轮4120套设在移动轴4210上。此外,移动轴4210上设置有挂耳6000,挂耳6000通过弹簧7000与双转子电机的外壳连接。弹簧7000通过挂耳拉动移动轴4210,通过移动轴4210带动第一皮带轮4120移动,实现对第二传动皮带4300和第一传动皮带4400的张紧。
采用前述双转子电机,通过两侧的第一转子1100和第二转子1200分别驱动烘干滚筒5100和风扇5200转动,利用了双转子电机结构紧凑的特性,减少了对衣物处理设备有限空间的占用。
以下对本公开实施例提供的衣物处理设备的控制方法流程图。图4 是本公开一些实施例提供的衣物处理设备的控制方法流程图。如图4所示,本公开实施例提供的衣物处理设备的控制方法包括S110。
S110:响应于目标烘干程序被触发,控制第一转子驱动烘干滚筒交替地正反转,以及控制第二转子驱动风扇持续地正转。
本公开实施例中,衣物处理设备中设置有多种对需烘干负载进行烘干类型选择的程序。
例如,在一些实施例中,烘干程序包括大件烘程序、常规烘程序、摇篮烘程序、贴壁烘。大件烘程序用于控制烘干滚筒交替地等时间正反转,避免大件需烘干负载过度缠绕的程序;常规烘干程序是用于控制烘干滚筒按照常规的正反节奏和转速圈速进行烘干的程序;摇篮烘程序是用于控制烘干滚筒类似摇篮一样交替地正反摆动,实现对易变形、易磨损负载进行烘干的程序。贴壁烘是用于控制烘干滚筒高速转动,利用烘干滚筒高速转动产生的离心力使得需烘干负载紧贴烘干滚筒内壁,并相对烘干滚筒内壁静止的程序。
具体实施中,在衣物处理设备上电工作后,衣物处理设备可以显示各种烘干程序对应的控制图标或者控制按键。用户可以通过选择对应的控制图标或者控制按键,实现对烘干程序的选择,确定目标烘干程序。
本公开实施例中的目标烘干程序为前述的大件烘程序。在用户选定大件烘程序并确定启动烘干操作指令后,衣物处理设备按照大件烘程序执行对需烘干负载的烘干操作。具体的,按照大件烘程序执行对需烘干负载的烘干操作包括:对烘干滚筒的动作控制,对风扇的控制和对制热装置的控制。
其如前分析,第一转子是驱动烘干滚动动作的动力源。相应的,对烘干滚筒的动作控制实质上是对第一转子的转动控制。本公开实施例中,衣物处理设备控制第一转子按照交替地正反转。第一转子交替地正反转,使得烘干滚筒也交替地正反转,继而可以使得需烘干负载交替地滚转,并通过需烘干负载的交替滚转避免其过度缠绕。
本公开实施例中,如前分析,第二转子是驱动风扇转动的动力源。相应的,对风扇的控制实质上是对第二转子的转子控制。本公开实施 例中,衣物处理设备控制第二转子按照第二转速驱动风扇转动。具体实施中,风机为离心风机。为使得控制第二转子驱动风扇转动时产生较大的气流流速,应当控制第二转子驱动风扇持续地正向转动。
本公开实施例中,衣物处理设备的制热装置为热泵装置。相应的,控制衣物处理设备中的热泵装置运行,是控制热泵装置的压缩机转动,同时合理地控制位于冷凝器和蒸发器之间的膨胀阀打开至合理地开度,利用蒸发器实现对流出烘干滚筒的含水气流的降温和水蒸气析出而形成干燥气流,利用冷凝器实现对前述干燥气流的加热,继而使得被加热的干燥气流流入到烘干滚筒内,利用被加热的干燥气流实现对贴壁的需烘干负载的加热,实现需烘干负载升温或者其中游离水的吸热蒸发,继而实现需烘干负载的干燥。
正是因为本公开实施例中衣物处理设备的烘干滚筒和风扇采用不同的驱动电机转动驱动转动,通过控制第一转子和第二转子独立地转动,利用第一转子驱动烘干滚筒交替地正反转而避免需烘干负载过度缠绕的同时,还可以始终保持风扇转动速率,进而保证烘干气流与需烘干负载的热交换速率。
本公开实施例中,为了能够尽可能地避免需烘干负载的过度缠绕。前述S110中控制第一转子驱动烘干滚筒交替地正反具体为控制第一转子按照第一正反转时间比驱动烘干滚筒交替地正反转。第一正反转时间比是表征烘干滚筒正转时间和反转时间的比值。具体实施中,第一正反转时间比设置在1:2到2:1之间。较为优先的,第一正反转时间比设置为1:1,也就是说第一转子正转设定时长后再反转设定时长。
本公开实施例中,衣物处理设备在驱动烘干滚筒交替地正反转之前,还需要确定第一正反转周期。第一正反转周期是第一转子完成一次完整的正反转所需要的时间。在确定第一正反转周期后,衣物处理设备控制第一转子按照第一正反转时间比和第一正反转周期驱动烘干滚筒交替地正反转。
实际应用中,根据需烘干负载类型的不同,造成需烘干负载过度缠绕所需的时间不同,因此需要合理地设置烘干滚筒单次的正转时间和时间。在一些具体实施中,烘干滚筒可以根据需烘干负载的类型和 前述的正反时间比,确定第一正反转动周期。需烘干负载的类型可以是用户启动衣物处理设备的烘干操作时选定,也可以是衣物处理设备采用诸如摄像头进行拍照检测得到。在另外一些具体实施中,衣物处理设备还可以将用户输入的转动周期作为第一正反转周期。
实际应用中,在第一转子驱动烘干滚筒转动的过程中,其一定是按照一定的转速运行,继而使得烘干滚筒内的需烘干负载能够持续地滚转。为实现前述目标,本公开实施例中,第一转子以第一转速驱动烘干滚筒转动。综合前述的其他条件,第一转子以第一转速、第一正反转时间比和第一正反转周期驱动烘干滚筒交替地正反转。
本公开实施例中,第二转子按照第二转速驱动风扇转动。前述的第二转速大于第一转速。通过将第二转速设置地大于第一转速,可以使得风扇处在高速运行状态,继而产生较大的烘干气流,加快需烘干负载的烘干速度。
在随着烘干的进行,需烘干负载的含水率逐渐地下降,直至达到判干条件。为了在需烘干负载达到判干条件后停止对需烘干负载的烘干操作,本公开实施例中,在执行前述的S110的过程中,还可以执行如下的S120-S130。
S120:获取需烘干负载的实时含水率,并判断实时含水率是否小于判干含水率;若是,执行S130;若否,继续执行S110。
在一些实施例中,衣物处理设备内可以设置有接触含水率检测传感器。前述获取需烘干负载的实时含水率具体可以为:获取接触传感器生成的含水率检测数据,并基于含水率检测数据确定需烘干负载的实时含水率。
在另外一些实施例中,衣物处理设备可以按照如下的S121-S123确定需烘干负载的实时含水率。
S121:控制第一转子按照第一设定参数驱动烘干滚筒转动,获取第一转子的第一运行参数。
第一设定参数可以是第一转子的转速,第一运行参数可以是第一转子按照前述转速转动时的转动功率或者转子扭矩。在此情况下,控制第一转子按照第一设定参数驱动烘干滚筒转动,是控制第一转子按 照恒定转速转动;相应的,获取第一转子的第一运行参数,是获取第一转子的转动功率或者转子扭矩。
S122:控制第二转子按照第二设定参数驱动风扇叶轮转动,获取第二转子的第二运行参数。
第二设定参数可以是第二转子的转速,第二运行参数可以是第二转子按照前述转速转动时的转动功率或者转子扭矩。在此情况下,控制第二转子按照第二设定参数驱动烘干滚筒转动,是控制第二转子按照恒定转速转动;相应的,获取第二转子的第二运行参数,是同时地检测第二转子的转动功率或者转子扭矩。
S123:根据第一运行参数和第二运行参数,确定需烘干负载的实时含水率。
在一些实施例中,衣物处理设备的处理器中设置有数据对照表,在确定第一运行参数和第二运行参数之后,可以根据第一运行参数和第二运行参数查找数据对照表,确定需烘干负载的实时含水率。
在另外一些实施例中,可以采用如下的S1231-S1233确定需烘干负载的实时含水率。
S1231:根据第一运行参数确定需烘干负载的初始重量。
在一些实施例中,预先确定特定类型需烘干负载初始重量和第一运行参数的对应关系表。在确定第一运行参数之后,可以基于转子扭矩查找对应关系表,确定需烘干负载的初始重量。
S1232:根据第二运行参数确定需烘干负载的估计体积。
在一些实施例中,预先确定特定类型需烘干负载估计体积和第二运行参数的对应关系表。在确定第二运行参数之后,可以基于第二运行参数查找对应关系表,确定需烘干负载的估计体积。
S1233:根据初始重量、估计体积和需烘干负载的干状态密度确定需烘干负载的实时含水率。
需烘干负载的干状态密度是预先实验确定的,需烘干负载在干燥状态下的密度。具体实施中,可以根据需烘干负载的类型查找确定其干状态密度。
在确定需烘干负载的干状态密度值之后,基于需烘干负载的干状 态密度和其估计体积,可以计算得到需烘干负载的干状态重量。在一些实施例中,需烘干负载在干状态下相对于湿状态体积有一定的增大,并且增大的比例根据需烘干负载的材质特性确定,因此可以根据需烘干负载的估计体积与预先设定的比例系数相乘,确定需烘干负载的干状态体积。采用初始重量减去前述的干状态重量,可以得到需烘干负载的初始含水量。采用前述初始含水量和估计体积相除,可以得到需烘干负载的实时含水率。
S130:控制第一转子和第二转子停转。
确定需烘干负载的实时含水率小于判干含水率,则可以控制衣物处理设备停止对需烘干负载的烘干操作。
本公开实施例中,停止对需烘干负载的烘干操作包括控制第一转子和第二转子停转,具体可以为:在确定实时含水率小于判干含水率后,仍然控制第二转子按照在前的第二转速运行预设时长,以及控制第一转子按照第三转速、第一正反转时间比和第二正反转周期运行预设时长,再控制第一转子和第二转子停转。前述的第三转速大于第一转速,第二正反转周期小于第一正反转周期。
实际应用中,因为制热装置仍然蓄积有较多的热量,为了能够充分利用制热装置的蓄积热量,本公开实施例中可以控制第一转子和第二转子继续运行设定时长后,再控制第一转子和第二转子停转,以利用第一转子和第二转子运行时充分的热传导将热量传递至需烘干负载。此外,如果将预设时长设置地较长,控制第一转子和第二转子继续运行设定时长,还可以起到对需烘干负载的降温作用。
此外,通过控制第一转子按照第三转速、第二正反转周期和第一正反转时间比转动,还可以实现对需烘干负载的抖散操作。
为了能够更为清晰地、按照时间顺序理解本公开实施例提供的衣物处理设备的控制方法,以下以另外一个完整实现需烘干负载烘干的实施例对衣物处理设备的控制方法再做分析。图5是本公开再一实施例提供的衣物处理设备的控制方法流程图,如图5所示,另一实施例提供的衣物处理设备的控制方法包括S310-S310。
S310:响应于大件烘程序被触发,控制第一转子按照第一转速、 第一正反转周期和第一正反转时间比驱动烘干滚筒转动,以及控制第二转子按照第二转速于驱动风扇转动,以及控制制热装置制热。
在一个具体实施中,前述的第一转速可以设置为2700rpm,第一正反转时间比可以设置为1:1,第一正反转周期设置为4min,第二电机转子的转速可以设置为3200rpm。此外,在制热装置为热泵制热装置的情况下,热泵制热装置中压缩机的频率可以设置为63Hz。
S320:获取需烘干负载的实时含水率;判断实时含水率是否小于判干含水率;若是,执行S330;若否,执行S310。
S330:确定实时含水率小于判干含水率,控制制热装置停止制热,控制第一转子按照第三转速、第二正反转周期和第一正反转时间比驱动烘干滚筒转动,以及继续控制第二转子按照第二转速驱动风扇转动,并开始进行计时。
本公开实施例中,第三转速可以设置为2900rpm,第一正反转时间比可以设置为1:1。通过控制第一转子按照第三转速、第二正反转周期和第一正反转时间比继续转动,可以实现对需烘干负载的抖散操作。
S340:确定计时时长达到预设时长,控制第一转子和第二转子停转。
本公开实施例中,预设时长可以设置为2min。

在一些实施例中,第一正反转时间比为1:1。
在一些实施例中,控制单元确定烘干滚筒的第一正反转动周期,并控制第一转子按照第一正反转时间比和第一正反转周期,驱动烘干滚筒交替地正反转。
在一些实施例中,控制单元根据需烘干负载的类型确定第一正反转周期,或者,将用户输入的转动周期作为第一正反转周期。
在一些实施例中,控制单元控制第一转子按照第一转速驱动烘干滚筒交替地正反转,以及控制第二转子按照第二转速驱动风扇持续地正转;其中,第二转速大于第一转速。
在一些实施例中,控制单元获取需烘干负载的实时含水率,并在确定实时含水率小于判干含水率的情况下控制第一转子和第二转子停转。

在一些实施例中,控制单元根据第一运行参数确定需烘干负载的估计重量,以及根据第二运行参数确定需烘干负载的估计体积;随后根据估计重量、估计体积和需烘干负载的干状态密度,确定需烘干负载的实时含水率。
