尤其是对于常规厚度的地毯,例如小于等于1/4英寸(约6mm)的地毯,尤其是软毛地毯,控制清洁机器人将拖地工作头抬升后,使得在所述清洁机器人在地毯上时,拖地工作头脱离地毯;需要说明的是,考虑到机器上地毯时,地毯会下陷一定高度,因此,控制抬升高度大于预设高度,例如6mm,可使得在所述清洁机器人在驶上地毯时,拖地工作头与地毯脱离;上述的脱离地毯可以理解为不接触地毯。
为了实现上述目的及其它目的,本公开的实施例还提供了一种清洁机器人,所述清洁机器人包括:机身;移动单元,设置于所述机身,用于支撑所述机身并带动所述清洁机器人在工作区域的表面移动;设有拖地工作头的拖地单元,所述拖地单元设置于所述机身,用于执行预设的拖地动作;控制单元,被配置为:控制所述拖地工作头抬升高度大于预设值,使得抬升后所述拖地单元的下表面与地毯的上表面之间存在间隙。
于上述实施例中的清洁机器人中,在清洁机器人对地面清洁过程中,为应对地面上的地毯,控制单元控制拖地工作头抬升,在清洁机器人驶上地毯时,抬升后的拖地单元的下表面与地毯的上表面之间存在间隙;避免了清洁机器人在驶上地毯时将地毯弄脏的问题,提高了清洁机器人的适应性。
对于常规厚度(如1/4英寸及以下)的地毯,为了实现抬升后的拖地单元的下表面与地毯的上表面之间存在间隙,在其中一个可能的实施方式中,控制拖地工作头抬升高度大于6mm,从而在机器驶上这些常规厚度的地毯时,拖地单元的下表面与地毯的上表面之间是存在间隙的;
在其中一个实施例中,控制单元被配置为:控制拖地工作头抬升,在清洁机器人驶上地毯时,抬升后的拖地单元的下表面与地毯的上表面之间的距离大于等于1mm,避免拖地单元污染地染。进一步的,抬升高度大于等于6.5mm,拖地单元的下表面与地毯的上表面之间是存在至少1mm间隙的;
进一步地,所述清洁机器人还包括:设有清扫工作头的清扫单元,所述清扫单元设置于所述机身,用于执行预设的清扫动作;所述清洁机器人被配置为至少包括清洁模式和拖地模式;控制单元被配置为:当所述清洁机器人处于清洁模式下,在所述清洁机器人检测到地毯 时,控制所述拖地工作头抬升,并控制所述清洁机器人驶上所述地毯,以便所述清扫单元对所述地毯执行所述清扫动作;其中,所述拖地工作头的抬升高度大于6mm,使得在所述清洁机器人在地毯上时,所述拖地工作头脱离所述地毯。
本实施例提供了一种扫拖一体清洁机器人,该清洁机器人至少具备清洁模式和拖地模式,在清洁模式下,清洁机器人在检测到地毯时,且确定要上地毯的情况下,控制拖地工作头处于抬升的状态下驶上地毯,控制清扫单元对地毯进行清扫,避免拖地工作头污染地毯的同时,实现了清扫单元对地毯的清洁。
进一步地,控制单元被配置为:当所述清洁机器人处于拖地模式下,在所述清洁机器人检测到地毯时,控制所述清洁机器人切换为非拖地模式,控制所述拖地工作头抬升,并控制所述清洁机器人驶上所述地毯;其中,所述拖地工作头的抬升高度大于6mm,使得在所述清洁机器人在地毯上时,所述拖地工作头脱离所述地毯。
在清洁机器人在拖地模式下对工作地面清洁的过程中,如果检测到地毯,控制清洁机器人先从拖地模式切换为非拖地模式,例如如果清洁机器人还具有清洁模式,则清洁机器人可以切换为清洁模式,由清扫单元对地毯进行清洁;而如果清洁机器人仅具有拖地功能或拖地模式时,此时,清洁机器人控制拖地工作头抬升起来,使得清洁机器人从拖地模式切换为跨越模式,清洁机器人跨过地毯后,再将拖地工作头降下来,再切换到拖地模式,继续对工作地面进行清洁。
进一步地,所述抬升高度同时满足小于等于20mm。
进一步地,所述拖地工作头在抬升过程中占据的空间体积为第一体积,所述清洁机器人的机身占据的空间体积为第二体积;其中,所述第一体积与第二体积的比值小于等于0.1。
为了使机器的整机尺寸不至于太大,同时整机内部布局合理,第一体积与第二体积的比值小于等于0.1。
在本公开的一个可能的实施方式中,控制抬升高度小于等于20mm,来使得第一体积与第二体积的比值小于等于0.1。
在本公开的一个实施例中,所述抬升高度同时满足小于等于机身的厚度与机身底面离地高度之和。
考虑到抬升的过高也可能影响机器零件的寿命或者会对撞上其它较高物体,因此,抬升高度需要满足小于等于机身的厚度与机身底面离地高度之和。
在本公开的一个实施例中,所述抬升高度同时满足小于等于机身的厚度与机身底面离地高度之差。
考虑到机身、拖地单元等部件是有一定厚度的,因此,抬升高度还需要满足小于等于机身的厚度与机身底面离地高度之差。例如,机身厚度为90mm,机身底面离地高度10mm,则抬升高度小于等于80mm。
需要说明的是,上述的机身底面离地高度可以理解为机身底面距离工作区域的表面的高度,也可以理解为机身底面距离地毯等软质材料的上表面的高度,对此本公开不做限定。
在本公开的一个实施例中,抬升高度大于等于6.5mm。
抬升高度大于等于6.5mm,使得清洁机器人在地毯上时,拖地工作头的的底面与地毯的表面之间存在一定的间隙,避免拖地单元污染地毯。
进一步地,所述拖地工作头在抬升过程中占据的空间体积为第一体积,所述清洁机器人的机身占据的空间体积为第二体积;其中,所述第一体积与第二体积的比值大于等于0.004。
为了保证拖地单元在执行拖地工作时的清洁效果,拖地工作头在抬升过程中占据的空间体积与清洁机器人的机身占据的空间体积的比值应满足大于等于0.004。
该实施例中,抬升高度大于等于6.5mm,使得清洁机器人在地毯上时,拖地工作头的的底面与地毯的表面之间存在一定的间隙,避免拖地单元污染地毯;同时为了保证拖地单元在执行拖地工作时的清洁效果,拖地工作头在抬升过程中占据的空间体积与清洁机器人的机身占据的空间体积的比值应满足大于等于0.004。
在本公开的一个实施例中,考虑到有些地毯厚度较大,例如厚度大于1/4英寸的地毯,以1/2英寸(约12.7mm)的地毯为例,为了避免污染此类地毯,抬升高度需大于12.7mm,例如控制抬升高度大于等于13mm。进一步地,抬升高度大于等于13mm。
在本公开的一个实施例中,考虑到清洁机器人在对工作区域进行清洁时,会遇到障碍物,例如台阶、玩具等,为了避免污染地毯,同时为了避免清洁机器人越障时,拖地工作头接触到工作区域的表面,可能造成的不良影响,例如造成损坏或者污染地面等问题,抬升高度大于等于15mm。
为了便于理解,下面对抬升高度的相关约束进行简要说明:
在本公开的一个实施例中,拖地工作头包括拖布板41,拖布板41具有拖布板底面积A1,拖地工作头具有抬升高度H1;清洁机器人100的机身10具有机身底面积A2,清洁机器人100的机身10具有机身高度H2;拖布板底面积A1和拖地工作头的抬升高度H1的乘积与机身底面积A2和机身高度H2的乘积之间的比值在预设的范围内。用数学公式表示即为,
Figure PCTCN2021135763-appb-000001
可以理解的,机身底面积A2与机身高度H2的乘积为清洁机器人100的机身10占据的空间体积,拖布板底面积A1与拖地工作头的抬升高度H1的乘积为拖地工作头在抬升过程中占据的空间体积。请参照图13a和图14,在拖布板底面积A1相同的情况下,拖地工作头抬升高度H1越高,占用清洁机器人100机身10内部的空间体积就越大,那么机身10内部其他功能模块的体积或位置会受到影响,进而影响到整机的布局。请参照图15和图16,在拖地工作头抬升高度H1相同的情况下,为了减小拖地工作头占据机身10内部的空间体积,可以减小拖布板底面积A1,但减小拖布板底面积A1,会影响拖地效果。在这种情况下,想要提高拖地工作头抬升高度H1,又要保障拖布板底面积A1大小不影响拖地效果,还要平衡拖地工作头占据机身10内部的空间体积,需要拖布板底面积A1和拖地工作头的抬升高度H1的乘积与机身底面积A2和机身高度H2的乘积之间的比值在一个合理的预设的范围内,即,拖地工作头在抬升过程中需要的空间体积占据机身10的体积要在一个合理的范围内,如此,才能使机器既满足清扫效果,又使得机身10内部合理布局,。在本实施例中,预设的范围是X1=0.004,X2=0.1,即,满足
Figure PCTCN2021135763-appb-000002
在本实施例中,以清洁机器人100的机身高度H2为87mm为例,请参考图17,当拖布板的宽度B1为25mm,拖布板的长度C1为200mm时,拖布板底面积A1大致为拖布板的宽度B1与拖布板的长度C1的乘积,A1=C1*B1;当机身底面的长度C2为400mm,机身底面的宽度B2为200mm时,机身底面积A2大致为机身底面的长度C2与机身底面的宽度B2的乘积,A2=C2*B2;拖地工作头的抬升高度H1大于或等于6.5mm,此时为了使机身10合理布局,拖布板底面积A1和拖地工作头的抬升高度H1的乘积与机身底面积A2和机身高度H2的乘积之间的比值处于预设的范围,该比值预设的范围通过计算为:
Figure PCTCN2021135763-appb-000003
仍以清洁机器人100的机身高度H2为87mm为例,请参考图17,当拖布板的宽度B1为175mm,拖布板的长度C1为400mm,拖布板底面积A1为拖布板的宽度B1与拖布板的长度C1的乘积,A1=C1*B1;机身底面的长度C2为400mm,机身底面的宽度B2为400mm,则机身底面积A2为机身底面的长度C2与机身底面的宽度B2的乘积,A2=C2*B2;拖地工作头的抬升高度H1小于或等于20mm,此时为了使机身10合理布局,拖布板底面积A1和拖地工作头的抬升高度H1的乘积与机身底面积A2和机身高度H2的乘积之间的比值处于预设的范围,该比值预设 的范围通过计算为:
Figure PCTCN2021135763-appb-000004
在本公开的一个实施例中,拖地工作头的抬升高度H1大于或等于15mm。拖地工作头处于拖地抬升位置以使拖地工作头处于非拖地状态,拖地工作头处于非拖地工作状态时包括一个场景,清洁机器人100对地毯进行清洁。清洁机器人100对地毯进行清洁时拖地工作头抬升,避免拖地工作头将地毯污染。在清洁机器人100驶上地毯时,如果地毯是软毛地毯或长毛地毯,清洁机器人100会陷入地毯的软毛或长毛中,机身的底面以及拖布板41的底面距离地毯的距离变短,若拖地工作头的抬升高度H1不够高,拖布板41还是会接触到地毯,造成地毯污染。此时需要拖地工作头能够抬升到一个更高的高度,拖地工作头抬升的高度大于15mm能够有效避免污染长毛或软毛地毯的情况出现。拖地工作头处于非拖地状态还包括一个场景,清洁机器人100越过障碍物。清洁机器人100越过障碍物时拖地工作头抬升,避免拖地工作头与地面接触干扰清洁机器人100越过障碍物。在清洁机器人100驶过障碍物时,机身10会产生一定角度的倾斜,若拖地工作头的抬升高度H1不够高,拖布板41还是会与地面接触,干扰清洁机器人100越过障碍物。此时需要拖地工作头能够抬升到一个更高的高度,拖地工作头抬升的高度大于15mm能够有效避免拖地工作头在清洁机器人100跨越障碍物时造成干扰。一般的满铺地毯,最高的高度在15mm左右,不同规格的清洁机器人在该地毯中可能下陷5-15mm,本公开中的清洁机器人的拖地工作头抬升高度大于15mm,因此在清洁机器人驶上该地毯时,将拖地工作头抬升不会碰到地毯,避免污染地毯。
进一步的,拖地工作头的抬升高度H1与机身的底面到地毯或地面的距离相关。对拖地工作头抬升高度H1的设置,应参考机身的底面到地毯或地面的距离,机身的底面到地毯或地面的距离越近,拖地工作头的抬升高度H1设置的越高,机身的底面到地毯或地面的距离越远,拖地工作头的抬升高度H1设置的越低。如此设置拖地工作头的抬升高度H1,清洁机器人100在驶上地毯或跨越障碍物时,拖地工作头可以有效避免污染地毯或干扰清洁机器人100跨越障碍物。
具体的,机身的底面到地毯或地面的距离与清洁机器人100自身的重量和清洁机器人100的万向轮21、驱动轮22的直径相关。可以理解的,清洁机器人100的重量越轻、清洁机器人100的驱动轮22、万向轮21的直径越大,机身的底面到地毯或地面的距离越远;清洁机器人100的重量越重、清洁机器人100的万向轮21、驱动轮22的直径越小,机身的地面到地毯或地面的距离越近。清洁机器人100的重量越轻、清洁机器人100的驱动轮22、万向轮21的直径越大,拖地工作头的抬升高度H1能够设置的越低;清洁机器人100的重量越重、清洁机器人100的万向轮21、驱动轮22的直径越小,拖地工作头的抬升高度H1需要设置的越高。
在清洁机器人100驶上地毯对地毯进行清洁时,若地毯是长毛或软毛地毯,清洁机器人100会陷入地毯中,清洁机器人100陷入地毯是指清洁机器人100的的万向轮21和驱动轮22会陷入地毯中。机身底面到地毯的距离与清洁机器人100陷入地毯的深度有关。清洁机器人100陷入地毯的深度越深,机身的底面到地毯的距离越小,拖地工作头的抬升高度H1需要设置的越高,清洁机器人100陷入地毯的深度越浅,机身的底面到地毯的距离越大,拖地工作头的抬升高度H1可以设置的越低。清洁机器人100陷入地毯的深度与清洁机器人100的重量、地毯的柔软度相关。可以理解的,清洁机器人100的重量越大、地毯越柔软,清洁机器人100陷入地毯的深度越深。
在本公开的一个实施例中,拖地状态切换组件驱动拖布板41沿垂直工作表面的方向升降运动,拖地状态切换组件至少部分与拖布板41连接,且拖地状态切换组件至少部分与拖布板41一起运动。拖地状态切换组件驱动拖布板41沿垂直工作表面的方向升降运动,以使拖布板41上的拖布接触或离开清洁机器人100的工作表面,可以理解的,拖地状态切换组件至少部分与拖布板41连接,可以是拖地状态切换组件与拖布板41直接连接,也可以是拖地状态 切换组件通过其他结构间接的与拖布板41连接。为了对工作表面进行有效清洁,拖布板41上的拖布应当与工作表面接触且对工作表面产生一定压力,请参照图18a、图18b,现有技术中为了使拖布板41上的拖布对工作表面进行有效清洁,会在拖布板41上设置配重块52,以增加拖布板41的重量对工作表面产生一定压力,此种设置,不仅会增加清洁机器人100的整体重量,配重块52也会占用清洁机器人100机身10内部的空间体积,进而使拖地工作头能够抬升的高度减小。
请参考图19a、图19b,在本实施例中,拖地状态切换组件至少部分与拖布板41连接,且拖地状态切换组件至少部分与拖布板41一起运动,如此,拖地状态切换组件可以起配重块作用;达到无需增加配重块便可有效清洁工作表面,同时节约了机身内部的空间,进而使拖地工作头能够抬升的高度增加。
换言之,拖地状态切换组件至少部分设置于拖布板41上并跟随拖布板41沿垂直工作表面的方向升降运动,设置于拖布板41上的至少部分拖地状态切换组件在驱动拖地工作头抬升的同时,起到了配重块52的作用。因此无需增加配重块52便可以使拖布板41有效清洁工作表面,同时节约了清洁机器人100机身10内部的空间体积,进而使拖地工作头能够抬升的高度增加。
进一步的,在本公开的一个实施例中提供的一种清洁机器人中,所述拖地工作头包括拖布板,用以安装擦拭件;所述拖地单元包括拖地状态切换组件,用于驱动所述拖布板沿垂直工作表面的方向升降运动。其中,上述的擦拭件例如可以是拖布、拖布纸或者海绵等。
进一步的,在本公开的一个实施例中,所述拖地工作头包括拖布板,用以安装擦拭件;所述拖地单元包括拖地状态切换组件,所述拖地状态切换组件与拖布板之间存在至少两个作用力点,拖地状态切换组件通过至少两个作用力点作用于所述拖布板上,实现将所述拖布板的抬升和下降。
例如,拖地状态切换组件可以包括两个凸轮,每个凸轮与拖布板之间具有一个作用力点,拖地状态切换组件通过两个凸轮与拖布板之间的作用力点实现拖布板的升降;
或者,拖地状态切换组件可以包括两个齿轮齿条结构,拖布板与齿轮齿条结构中的齿轮相连,每个齿轮齿条结构与拖布板之间存在一个作用力点,每个齿轮齿条结构中的齿轮沿齿轮齿条结构中的齿条作升降运动,通过两个作用力点作用于拖布板,从而带动拖布板升降运动。
进一步的,拖地状态切换组件包括驱动单元、齿轮53以及与齿轮53啮合的齿条54,驱动单元驱动齿轮53旋转,以使齿轮53和齿条54中的一个沿垂直工作表面的方向升降,齿轮53与齿条54中的一个与拖布板41连接,并带动拖布板41沿垂直工作表面的方向升降运动。可以理解的,拖布板41沿垂直工作表面的方向升降可以是拖布板41沿竖直方向直上直下的移动,也可以是拖布板41沿略倾斜的方向上下移动,只要产生垂直工作表面方向上的位移,均可视为沿垂直工作表面的方向升降运动。优选的,驱动单元包括驱动电机52。驱动电机52的输出端与齿轮53啮合以带动齿轮53旋转。
更进一步的,请参考图19a、图19b,齿条54与机身10连接,驱动单元以及齿轮53与拖布板41连接,并与拖布板41一起运动,驱动单元驱动齿轮53在齿条54表面移动,以带动拖布板41沿垂直工作表面的方向升降运动。请参考图19、图20a、图20b,驱动单元与拖布板41相对固定连接,驱动单元驱动齿轮53旋转,使得齿轮53在齿条54表面爬升或下降,齿轮53在齿条54表面爬升或下降的同时带动驱动单元和拖布板41升降,从而实现拖布板41沿垂直工作表面的方向升降运动,同时由于驱动单元和齿轮53连接于拖布板41,将驱动单元和齿轮53的重量增加在拖布板41上,使得拖布板41可以有效清洁工作表面。
请参考图18a、图18b,是现有技术中齿轮与齿条配合使拖布板抬升的一种技术方案,齿轮与机身连接,齿条与拖布板连接,驱动单元与机身连接,并驱动齿轮旋转,齿轮旋转带动齿条连同拖布板一起沿垂直工作表面的方向升降运动,此种设置仍需要增加配重块在拖布板上,以使拖布板与工作表面接触时能够有效清洁工作表面,且在拖布板抬升过程中齿条会向 上运动,为了将齿条容纳在机身内部,机身的高度需要增高,而过高的机身使机器人无法进入低矮家具的底部,影响清洁效果。本实施例中,齿条54与机身10连接,在拖布板41抬升的过程中相对机身10固定,驱动单元52与拖布板连接,齿轮通过驱动单元52间接与拖布板41连接,驱动单元52驱动齿轮53旋转并在齿条54表面爬升或下降,齿轮53带动拖布板41沿垂直工作表面的方向升降运动的同时,齿轮53和驱动单元52的重量加持在拖布板上41,因此无需额外增加配重块也可以使拖布板41与工作表面接触时能够有效清洁工作表面,且由于齿轮53在拖布板41抬升的过程中相对机身10固定,机身高度无需额外增加即可容纳齿条54,可以降低机身10高度,便于清洁机器人进入低矮家具的底部,提高清洁效果。
进一步地,在本公开的一个实施例中,拖地状态切换组件包括第一切换件、第二切换件,第一切换件和第二切换件连接拖布板41并设置于拖布板中轴线L的两侧,第一切换件和第二切换件配合以带动拖布板41沿垂直工作表面的方向升降运动。
进一步地,在本公开的一个实施例中,所述拖布板中轴线将拖布板分为两部分,第一切换件和第二切换件设置于拖布板中轴线L的两侧,一起带动拖布板升降。拖布板的中轴线将拖布板分成两部分,上述的两部分并不完全相同;当然,所述拖布板中轴线也可以将拖布板分为形状大小相等的两部分。
在本实施例中,拖布板41为平板式结构,拖布板中轴线L将拖布板41分为形状大小相等的两部分,第一切换件和第二切换件设置于拖布板中轴线L的两侧,一起带动拖布板41升降,可以使拖布板41在升降的过程中更加平衡。优选的,第一切换件和第二切换件与拖布板41连接的位置相对于拖布板中轴线L对称。如此设置,可以使拖布板41太抬升过程中受力更加均匀,抬升的更加平稳。
具体的,请参照图20a、20b,第一切换件包括相互啮合的第一齿轮531和第一齿条541,第二切换件包括相互啮合的第二齿轮532和第二齿条542,第一齿轮531和第一齿条541设置在拖布板中轴线L的一侧,第二齿轮532和第二齿条542设置在拖布板中轴线L的另一侧,第一齿轮531和第二齿轮532连接于拖布板41,第一齿轮531和第二齿轮532分别在第一齿条541和第二齿条542表面爬升或下降,以带动拖布板41沿垂直工作表面的方向升降运动。拖布板重心G位于拖布板中轴线L上,拖布板41在抬升过程中受到的抬升力F设置在拖布板重心G的两侧,相较于受到单侧抬升力,受到两侧抬升力F可以使拖布板在抬升过程中更加平衡、平稳。
在本公开的一个实施例中,拖地状态切换组件还包括连接件,用以带动第一切换件的至少部分和第二切换件的至少部分同时产生垂直工作表面方向的升降。进一步的,拖地状态切换组件还包括连接件55,连接第一切换件和第二切换件,驱动单元驱动连接件55运动以带动第一切换件的至少部分和第二切换件的至少部分同时产生垂直工作表面方向的升降。通过连接件55驱动单元可以同时驱动第一切换件的至少部分和第二切换件的至少部分产生垂直工作表面的方向升降,使拖布板41在升降过程中更加平稳。
具体的,连接件55连接第一齿轮531和第二齿轮532,驱动单元驱动连接件55旋转,以使连接件55带动第一齿轮531和第二齿轮532同时旋转,第一齿轮531和第二齿轮532同时又分别在第一齿条541和第二齿条542的表面爬升或下降。在本实施例中,连接件55包括有连杆,连杆一端连接第一齿轮531,另一端连接第二齿轮532。第一齿轮531和第二齿轮532通过驱动单元间接连接至拖布板41,并带动驱动单元和拖布板41沿垂直工作表面的方向升降运动,在其他实施例中第一齿轮531和第二齿轮532也可以直接与拖布板41连接。
进一步地,在本公开的一个实施例中,请参考图11a、图11b、图11c及图11d,所述清扫单元与所述拖地单元可以至少部分重叠设置,并且所述拖地单元可以部分与机身可分离的设置;所述控制单元被配置为:
根据接收的所述至少单拖及/或单扫控制信号,控制所述移动单元移动并带动所述清洁机器人返回至预设的装载拖布区域(例如充电基站的内部区域),进行单拖和单扫状态的切换。
所述预设的装载拖布区域放置有预设形状大小的拖布板,所述状态切换过程如下:所述 清洁机器人在单扫状态下,边刷和滚刷接触所述工作表面,当所述清洁机器人接收到单拖控制信号后,所述清洁机器人返回并精确地停靠在所述装载拖布的预设区域,此时所述边刷工作头精确地位于拖布板正上方预设位置,控制设置于机身内部的拖布板夹持机构(图中未示出)将所述拖布板固定连接在机身上,由于边刷位于拖布板正上方,因此边刷不接触所述工作表面,同时所述单拖控制信号控制所述滚刷抬升机构抬升所述滚刷远离所述工作表面,完成从单扫到单拖的状态切换。当所述清洁机器人接收到单扫控制信号后,所述清洁机器人返回所述装载拖布区域,卸载所述拖布板,并控制所述滚刷抬升机构放下所述滚刷工作头,使得滚刷工作头和边刷工作头接触所述工作表面,完成从单拖到单扫的状态切换。
滚刷工作头具有与工作区域表面接触的滚刷工作位置和与工作区域表面脱离接触的滚刷抬升位置。当所述清扫工作头处于所述清扫状态时,所述滚刷处于所述滚刷工作位置,当所述清扫工作头处于所述非清扫状态时,所述滚刷处于所述滚刷抬升位置,以便于控制清扫工作头中的滚刷在清扫状态与非清扫状态之间进行状态切换。
如图12a、图12b、图12c及图12d,所述控制单元还被配置为根据获取的所述单拖控制信号控制所述滚刷工作头离开所述表面,以避免在单独拖地时滚刷工作头的粘有灰尘的第二清洁部污染待拖地的表面。
