具体实施方式
下面将结合附图,对本公开一些实施例进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开所提供的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本公开保护的范围。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言,其不排除适用于或被配置为执行额外任务或步骤的设备。
在本申请的描述中,需要理解的是,术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本申请和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本申请的限制。
在下文中,为便于描述,如无特殊说明,本公开对于上、下、左、右、前、后的方位表述均以室内机运行时的状态为参考。室内机运行时面向用户的一侧为前侧,与之相反的一侧为后侧。室内机的高度方向为上、下方向。室内机的长度方向为左、右方向,室内机的厚度方向为前、后方向。
空调器1通常包括分体式空调器1和一体式空调器1,分体式空调器1包括室内机和室外机,一体式空调器是将所有空调器1包括的器件集成在一个壳体内,通常,一体式空调器可以在房间内随意移动。本公开一些实施例可以应用于分体式空调器或一体式空调器。
以分体式空调器为例,室内机包括室内换热器、室内风机和室内膨胀阀,室外机包括 室外换热器、压缩机、室外膨胀阀。压缩机、冷凝器(室内换热器或室外换热器)、膨胀阀(室内膨胀阀和室外膨胀阀)和蒸发器(室外换热器或室内换热器)来执行空调器1的冷媒循环。冷媒循环包括一系列过程,涉及压缩、冷凝、膨胀和蒸发,并向被调节侧循环供应冷媒。室内风机被配置为促进在室内换热器的传热管中流动的冷媒与室内空气的热交换,以辅助温度调节。
随着空调的广泛使用,用户对于空调的要求也在不断提升。室内机包括进风口和出风口。进风口处设置有滤网,以过滤进入室内机的空气,阻挡空气中的灰尘等杂物进入到室内机内。室内机在运行一段时间后,附着在滤网上的灰尘等杂物过多,可能会堵塞部分滤网,导致进风量减少,从而降低空调的制冷或制热效率。
通常情况下,在室内机内设置滚刷,通过滚刷清除滤网上附着的杂物,使滤网保持较高的过滤能力,从而维持室内机制冷或制热的效率。当室内机工作一段时间,滤网上附着的杂物较多,会有将过滤组件拆卸下来以对过滤组件中的滤网和滚刷等结构进行清洗的需求。在拆卸过滤组件过程中,由于驱动滤网相对滚刷运动的驱动电机与滤网连接,因此需先将驱动电机拆卸后才能将过滤组件拆卸。然而,在拆卸过滤组件时,会发生因接触驱动电机而导致触电的安全隐患。并且,过滤组件不易安装和拆卸,使得室内机的装配效率较低,不利于用户清洗过滤组件。
本公开的一些实施例提供了一种室内机1000,如图1、图4、图5和图10所示,室内机1000包括壳体100、过滤组件200、自清扫组件300、驱动组件400和传动组件500(见图11)。
如图18所示,壳体100包括第一板191、第二板192、第三板193和第四板194。第一板191是当室内机安装在室内的墙体上时,远离墙体的一侧的侧板。第二板192是当室内机安装在室内的墙体上时,靠近墙体的一侧的侧板。第一侧板193和第四板194分别连接第一板191和第二板192,且分别沿垂直于第一板191和第二板192的方向延伸。例如,第一侧板193是壳体100的长度方向(即如图1所示的左右方向)上的一侧的侧板,第四板194是壳体100的长度方向(即如图1所示的左右方向)上的另一侧的侧板。例如,第一侧板193是室内机1000左侧的一侧板,第四板194是室内机1000右侧的一侧板。
壳体100包括进风口110。例如,壳体100的顶部的一部分敞开,以形成进风口110。过滤组件200设置在壳体100内,且位于进风口110处。过滤组件200被配置为过滤从进风口110进入室内机1000的空气,以防止空气中的杂物进入室内机1000。自清扫组件300设置在壳体100内,且被配置为清除附着在过滤组件200上的杂物。
驱动组件400设置在壳体100上,传动组件500设置在壳体100内。传动组件500分别连接自清扫组件300和驱动组件400,且被配置为在驱动组件400的驱动下,带动自清扫组件300运动,以使自清扫组件300清除附着于过滤组件200上的杂物,以进行自清扫工作,从而实现维持室内机1000制冷或制热的效率。
在一些实施例中,如图2和图5所示,室内机1000还包括室内换热器600、第一风机组件700和出风口。室内换热器600设置在壳体100内,且被配置为与从进风口110进入的室内空气进行换热。第一风机组件700设置在室内换热器600远离进风口110的一侧,且被配置为吸入和泵出室内空气。
例如,第一风机组件700工作时,风机旋转,将室内空气从进风口110吸入,使室内空气与室内换热器600换热,然后将经室内换热器600换热后的室内空气从出风口泵出。室内机1000通过室内换热器600对室内空气进行加热或冷却,以使室内温度升高或降低,实现制热或制冷的效果。
在一些实施例中,如图6、图7A和图7B所示,过滤组件200包括滤网210。滤网210设置在进风口110和室内换热器600之间(如图5所示),并且覆盖进风口110,使得滤网210可以过滤从进风口110进入室内机1000的空气中的杂物。
自清扫组件300包括第一基座310、第一清洁刷320、第一卷轴330和第二卷轴340。第一基座310设置在壳体100内,且包括第二安装部311和第一支架312。第一支架312的一侧与第二安装部311的靠近第二板192的一侧连接,且沿室内机1000的厚度方向(如 图7A所示的前后方向)延伸。第二安装部311内限定有第一腔313(例如为安装腔),且第一腔313的顶部的一部分敞开。第一支架312被配置为承载滤网210。滤网210设置在第一支架312上,且可以相对于第一支架312运动。
第一清洁刷320、第一卷轴330和第二卷轴340可转动地设置在第一腔313内,且第一清洁刷320、第一卷轴330和第二卷轴340分别沿室内机1000的长度方向延伸。第一清洁刷320包括第一毛刷321,且被配置为清除附着在滤网210上的杂物。第一清洁刷320靠近第一卷轴330设置。第一卷轴330与第二卷轴340间隔开设置,且大致平行。滤网210的一端连接第一卷轴330,另一端连接第二卷轴340。滤网210卷绕在第一卷轴330和第二卷轴340中的至少一者的外周,且滤网210张紧于第一卷轴330与第二卷轴340之间。
在一些实施例中,如图10和图11所示,传动组件500设置在第一基座310中,且传动组件500分别连接第一卷轴330和第二卷轴340。传动组件500通过第一卷轴330和第二卷轴340与滤网210连接。
驱动组件400设置在壳体100上,且驱动组件400包括驱动齿轮410。驱动齿轮410连接动力输出端。驱动组件400的动力输出端与传动组件500可拆卸地连接。例如,驱动组件400为驱动电机。驱动组件400通过传动组件500可以带动第一卷轴330和第二卷轴340沿相反方向转动,以驱动滤网210沿预定轨迹运动。即,第一清洁刷320与滤网210之间发生相对运动,使得滤网210的不同区域与第一清洁刷320相对设置。
例如,驱动组件400通过传动组件500带动第一卷轴330和第二卷轴340转动,使滤网210在第一卷轴330上收卷,且在第二卷轴340上放卷,或者,使滤网210在第一卷轴330上放卷,且在第二卷轴340上收卷,从而使得滤网210张紧在第一卷轴330和第二卷轴340之间,并且相对于第一清洁刷320运动。这样,第一清洁刷320可以对与其相对的滤网210区域进行清扫。
传动组件500包括第一从动齿轮510、第二从动齿轮520、第三从动齿轮530和中间齿轮540。第一从动齿轮510安装于第一卷轴330的一端,第一从动齿轮510与驱动齿轮410啮合。第二从动齿轮520安装于第二卷轴340的一端,第二从动齿轮520与第一从动齿轮510啮合。第三从动齿轮530安装于第一清洁刷320的一端,第三从动齿轮530与中间齿轮540啮合。第一从动齿轮510还与中间齿轮540啮合。
在自清扫组件300工作的过程中,驱动组件400运转,使动力输出端上的驱动齿轮410沿第一方向旋转,以带动第一从动齿轮510沿第二方向旋转,进而带动第一卷轴330沿所述第二方向转动。同时第一从动齿轮510还带动第二从动齿轮520沿所述第一方向旋转,进而带动第二卷轴340沿所述第一方向转动。
这样,在第一卷轴330和第二卷轴340的作用下,张紧在第一卷轴330和第二卷轴340之间的滤网210沿预定轨迹运动,使得滤网210上的不同区域依次与第一清洁刷320相对,并由第一清洁刷320对不同区域的滤网210进行清扫。
需要说明的是,所述第一方向与所述第二方向相反。当第一卷轴330沿所述第一方向转动,并收卷滤网210时,第二卷轴340沿所述第二方向转动,并放卷滤网210。
例如,参考图7A、图7B和图11,第一从动齿轮510在驱动齿轮410的驱动下沿逆时针方向旋转,并带动第一卷轴330沿逆时针方向转动,以收卷滤网210。然后,第一从动齿轮510在沿逆时针方向旋转的同时带动第二从动齿轮520沿顺时针方向旋转,从而带动第二卷轴340沿顺时针方向转动,并放卷滤网210。
可以理解的是,第一从动齿轮510在驱动齿轮410的驱动下沿顺时针方向旋转,并带动第一卷轴330沿顺时针方向转动,以放卷滤网210。然后,第一从动齿轮510在沿顺时针方向旋转的同时带动第二从动齿轮520沿逆时针方向旋转,从而带动第二卷轴340沿逆时针方向转动,并收卷滤网210。
此外,第一从动齿轮510还同时带动中间齿轮540沿所述第一方向旋转,从而中间齿轮540带动第三从动齿轮530沿所述第二方向旋转,进而带动第一清洁刷320沿所述第二方向旋转,使得第一清洁刷320的转动方向与滤网210运动的方向相反,从而有利于提高 第一清洁刷320对滤网210的清洁效果。
例如,第一从动齿轮510和第二从动齿轮520的齿数一致,以使第一卷轴330和第二卷轴340的转速一致,使得滤网210张紧在第一卷轴330和第二卷轴340上。
在一些实施例中,如图10、图11和图12所示,第一基座310还包括第二腔314。第二安装部311的沿室内机1000的长度方向上的一侧朝向另一侧凹进,以形成第二腔314。传动组件500设置在第二腔314内,即第一从动齿轮510、第二从动齿轮520、第三从动齿轮530和中间齿轮540分别设置在第二腔314内。在第一基座310上设置第二腔314,有利于保护和隐藏第一从动齿轮510、第二从动齿轮520、中间齿轮540和第三从动齿轮530,有利于在室内机1000中走线,以及防止运转的部件(例如中间齿轮540)对其它部件(例如第一风机组件700)造成损害。
在一些实施例中,如图12所示,第二腔314的底侧设有连通第一腔313的第一开口3141、第二开口3142和第三开口3143。如图14所示,第一从动齿轮510的中部设有第一棱柱511,第一卷轴330的端部上设有与第一棱柱511适配的第一孔,第一棱柱511穿过第一开口3141并插设至所述第一孔内,以使第一从动齿轮510与第一卷轴330固定连接。
第二从动齿轮520的中部设有第二棱柱521,第二卷轴340的端部上设有与第二棱柱521适配的第二孔,第二棱柱521穿过第二开口3142并插设至所述第二孔内,以使第二从动齿轮520与第二卷轴340固定连接。第三从动齿轮530的中部设有第三棱柱531,第一清洁刷320的端部上设有与第三棱柱531适配的第三孔,第三棱柱531穿过第三开口3143并插设至所述第三孔内,以使第三从动齿轮530与第一清洁刷320固定连接。
在室内机1000中设置第一开口3141、第一棱柱511、所述第一孔、第二开口3142、第二棱柱521、所述第二孔、第三开口3143、第三棱柱531以及所述第三孔,有利于实现第一从动齿轮510与第一卷轴330的连接、第二从动齿轮520与第二卷轴340的连接、以及第三从动齿轮530与第一清洁刷320的连接,从而可以提高转动的稳定性。
这样,室内空气在第一风机组件700的作用下从进风口110进入壳体100内,并经过滤网210的过滤后流向室内换热器600。室内空气经室内换热器600换热后从出风口吹出。
当室内机1000工作一段时间后,室内空气中的杂物经滤网210过滤后会在滤网210的表面上堆积,使滤网210上附着较多的杂物,影响滤网210的过滤效果和进风效果。当滤网210上附着的杂物较多时,室内机1000的自清扫组件300可以清除滤网210上附着的杂物,使滤网210保持过滤能力,从而提高室内机1000制冷或制热的效率。
在一些实施例中,如图8A和图8B所示,第一卷轴330包括第一部分331和第二部分332,且第一部分331与第二部分332可拆卸连接。第二卷轴340包括第三部分341和第四部分342,且第三部分341与第四部分342可拆卸连接。滤网210的一端夹持于第一部分331与第二部分332之间,滤网210的另一端夹持于第三部分341与第四部分342之间。
需要说明的是,将第一卷轴330和第二卷轴340分别设置为可拆卸连接的两部分结构,并通过夹持的方式将滤网210的两端分别固定在第一卷轴330和第二卷轴340上,可以提高滤网210连接第一卷轴330和第二卷轴340的稳定性,有利于维持滤网在第一卷轴330和第二卷轴340之间的张紧。
第一部分331、第二部分332、第三部分341和第四部分342分别沿室内机1000的厚度方向(如图8A和图8B所示的前后方向)延伸,且截面呈弧形的条形结构。第一部分331、第二部分332、第三部分341和第四部分342的外侧面平滑,有利于使滤网210在第一卷轴330和第二卷轴340上收卷和放卷。
第一部分331的内侧面上设有第一卡扣部333,第二部分332的内侧面上设有第二卡扣部334。第一卡扣部333与第二卡扣部334卡扣连接,使得第一部分331和第二部分332可拆卸连接。第三部分341的内侧面上设有第三卡扣部343,第四部分342的内侧面上设有第四卡扣部344。第三卡扣部343与第四卡扣部344卡扣连接,使得第三部分341和第四部分342可拆卸连接。这样,通过卡扣的方式实现第一部分331与第二部分332、第三部分341与第四部分342的连接,有利于方便用户取出滤网210进行清洗。
在一些实施例中,参考图9、图10和图15,室内机1000包括多个过滤组件200和多个自清扫组件300。壳体100包括多个进风口110。每个过滤组件200分别与一个自清扫组件300对应,每个进风口110分别与一个过滤组件200对应。
可以理解的是,室内机1000中设置多个进风口110、多个过滤组件200和多个自清扫组件300,有利于提高室内机1000的进风量和出风量,从而提高室内机1000制冷或制热的效率。
室内机1000还包括多个驱动组件400和多个传动组件500,且每个驱动组件400分别与一个传动组件500对应。各驱动组件400通过与自身对应的传动组件500与过滤组件200连接。这样,各过滤组件200可以被单独驱动,以进行自清扫工作。
在一些实施例中,如图13和图14所示,室内机1000还包括至少一个连杆550,多个传动组件500之间通过连杆550连接,驱动组件400的动力输出端与连杆550连接。这样,驱动组件400可通过连杆550和多个传动组件500驱动多个自清扫组件300工作,有利于简化室内机1000的结构。
在一些实施例中,如图12所示,第一基座310还包括缺口315。例如,第二腔314的靠近第二板192的一侧敞开,以形成缺口315。第一从动齿轮510的一部分从缺口315伸出,驱动齿轮410与第一从动齿轮510的所述一部分啮合。
可以理解的是,传动组件500和驱动组件400的可拆卸连接是通过第一从动齿轮510和驱动齿轮410之间的啮合而实现的。在第一基座310上设置缺口315,有利于实现驱动齿轮410与第一从动齿轮510啮合。当拆卸传动组件500时,第一从动齿轮510可以随第二安装部311一起从壳体100上拆卸,而驱动齿轮410不会随第二安装部311一起从壳体100上拆卸。
也就是说,由于驱动组件400的动力输出端和传动组件500可拆卸连接,而传动组件500与自清扫组件300连接,过滤组件200与自清扫组件300连接。因此,当用户需要拆卸过滤组件200和自清扫组件300,对过滤组件200和自清扫组件300进行清洗时,可以将第一基座310从壳体100上拆卸,以将自清扫组件300从壳体100上拆卸。同时,传动组件500随自清扫组件300一起从壳体100上拆卸,而驱动组件400不会随传动组件500一起从壳体100上拆卸。
这样,用户可以在不接触驱动组件400的前提下拆卸过滤组件200和自清扫组件300,对过滤组件200和自清扫组件300进行清洗,有利于避免因接触驱动组件400引发的安全隐患。并且,驱动组件400隐藏在壳体100内,有利于得到保护,避免受外界作用而损坏。
在一些实施例中,如图2所示,壳体100还包括第一连接部120和第一安装部130(例如为安装槽)。例如,壳体100的前侧的一部分敞开,以形成第一连接部120。壳体100内限定有第一安装部130。第一安装部130的前侧敞开。第一连接部120与第一安装部130连通,且第一连接部120位于第一安装部130的上方。第二安装部311设置在第一安装部130内。自清扫组件300设置在第二安装部311的内侧,传动组件500设置在第二安装部311的外侧。第一支架312通过第一连接部120设置在壳体100内。
由于第一卷轴330、第二卷轴340和第一清洁刷320设置在第二安装部311内,第二安装部311设置在第一安装部130内,第一支架312的一侧与第二安装部311连接,且通过第一连接部120向后侧延伸。因此,用户可以通过第一连接部120,将第二安装部311从第一安装部130中拆卸,使第一支架312和滤网210随着第二安装部311一起从壳体100上拆卸,实现拆卸过滤组件200和自清扫组件300。这样,有利于降低拆卸和安装过滤组件和自清扫组件的难度,方便用户清洗拆卸下来的过滤组件200和自清扫组件300。
同理,用户可以通过第一连接部120,将第二安装部311安装在第一安装部130内,使第一支架312和滤网210随着第二安装部311一起安装在壳体100内,实现安装过滤组件200和自清扫组件300。
在一些实施例中,如图9所示,室内机1000还包括第一限位部160(例如为限位块)。第一限位部160转动设置在壳体100的第一板191上,且靠近第一安装部130。第一限位部160被配置为在锁止位置和解锁位置之间转动切换。
例如,当第一限位部160处于锁止位置上时,第一限位部160至少一部分处于第二安装部311的前侧上以阻碍第二安装部311从第一安装部130中滑出。当第一限位部160处于解锁位置上时,第一限位部160处于壳体100的第一板191上以使第二安装部311能够向前滑动,以脱离第一安装部130。
需要说明的是,室内机1000工作时,第一限位部160处于锁止位置,以防止第二安装部311从第一安装部130中滑出。当需要对过滤组件200进行清洗时,将第一限位部160旋转至解锁位置,可以取出第二安装部311。
例如,室内机1000包括多个第一限位部160。在壳体100上设置多个第一限位部160,有利于用户拆卸和安装过滤组件200。
在一些实施例中,如图15所示,自清扫组件300还包括第一集尘盒350和落灰盒360。第一集尘盒350设置在第一基座310上,且位于第一清洁刷320的下方。第一集尘盒350被配置为收集从滤网210上清除的杂物。
如图3和图9所示,室内机1000还包括第三卡槽150。第三卡槽150设置在壳体100的第一板191上。落灰盒360设置在第三卡槽150内,且落灰盒360位于第一集尘盒350的下方。第三卡槽150具有沿室内机1000的长度方向(即如图9中的左右方向)间隔设置的第一侧壁151和第二侧壁152。第一侧壁151上设有第一卡槽153,第二侧壁152上设有第二卡槽154。如图12所示,落灰盒360上设有沿室内机1000的长度方向(即如图9中的左右方向)间隔设置的第一卡块和第二卡块。
通过第一卡块和第一卡槽153的配合,以及第二卡块和第二卡槽154的配合,以将落灰盒360可拆卸地安装在第三卡槽150内。
在一些实施例中,如图15和图16所示,自清扫组件300还包括第二清洁刷370。第二清洁刷370设置在第一集尘盒350内,且被配置为将第一清洁刷320上附着的杂物刷除至第一集尘盒350内。第二清洁刷370包括第二毛刷371,第二毛刷371被配置为插入至第一清洁刷320内。
在一些实施例中,室内机1000的清洁刷包括第一清洁刷320和第二清洁刷370。
自清扫组件工作时,部分杂物会附着在第一毛刷321上,第二毛刷371可以将第一毛刷321上附着的杂物刷除至第一集尘盒350内,使得第一毛刷321可以在不附着有杂物的情况下接触滤网210并清除滤网210上附着的杂物,有利于提高清扫滤网230的效果。
在一些实施例中,如图1和图4所示,室内机1000还包括面板800。面板800可拆卸连接在壳体100的前侧,以封堵第一连接部120。例如,在室内机1000工作时,面板800盖设在壳体100的前侧,以使室内机1000的外观协调。当需要拆卸清洗过滤组件200和自清扫组件300时,可以将面板800从壳体100的前侧拆卸后,再通过第一连接部120将过滤组件200和自清扫组件300从壳体100上拆卸。
如图2所示,面板800的内侧面上设有第一配合部,壳体100的前侧上设有第二配合部140,第一配合部和第二配合部140通过卡扣连接,以使面板800可拆卸连接在壳体100的前侧上。
在一些实施例中,如图17所示,滤网210包括依次连接的过滤部211和封堵部212。过滤部211被配置为过滤从进风口110进入壳体100内的空气,封堵部212被配置为阻隔从进风口110进入壳体100内的空气。
例如,当滤网210沿预定轨迹运动时,滤网210可以在过滤位置和封堵位置之间运动。当滤网210处于所述过滤位置时,过滤部211覆盖进风口110,过滤从进风口110进入壳体100内的空气。当滤网210处于所述封堵位置时,封堵部212覆盖进风口110,以阻隔从进风口110进入壳体100内的空气。
需要说明的是,当室内机1000工作时,滤网210处于所述过滤位置上,过滤部211覆盖进风口110并过滤从进风口110进入的空气。当室内机停机时,滤网210从所述过滤位置运动至所述封堵位置上,封堵部212覆盖进风口110,使得空气和灰尘被封堵部212阻挡,避免灰尘进入到壳体100内部。
可以理解的是,过滤部211为具有多个孔径较小的孔的区域,过滤部211上的所述多 个孔可以过滤空气中的大颗粒的灰尘等杂物,使空气经过滤后进入壳体100中。封堵部212为无孔的区域,空气和灰尘不能通过。例如,封堵部212由塑料膜制成,封堵部212和过滤部211之间设有用于连接封堵部212和过滤部211的热融部。
如此一来,通过在滤网210中设置封堵部212,可以使室内机1000在停机时,空气和灰尘无法进入壳体100中,从而避免灰尘等杂物进入壳体100内部,以防止灰尘等杂物附着在壳体100内的室内换热器600或第一风机组件700上,使得室内机1000的内部更加洁净,有利于提高室内机1000的制冷或制热效果。
在一些实施例中,室内机1000还包括传感器和控制器。所述传感器被配置为向所述控制器发送代表运行自清扫模式的信号。例如,所述信号为指示室内机1000运行或停止自清扫模式的信号。当滤网210上的杂物达到预设量时,所述传感器向所述控制器发送代表运行自清扫模式的信号。当滤网210上的杂物低于预设量时,所述传感器向所述控制器发送代表停止自清扫模式的信号。
所述控制器被配置为接收所述传感器发出的信号,并响应于所述信号,控制室内机1000执行所述信号指示的操作。例如,当接收到所述传感器发出的代表运行自清扫模式的信号时,控制室内机1000运行自清扫模式。当接收到所述传感器发出的代表停止自清扫模式的信号时,控制室内机1000停止自清扫模式。
例如,室内机1000在工作一段时间后,由于室内空气在第一风机组件700的作用下不断从进风口110流向室内换热器600,并在室内换热器600换热后被第一风机组件700从出风口送向室内。因此,室内机1000内与进风口110相对的滤网210上附着的杂物增加。当滤网210上的杂物达到所述预设量时,所述传感器将向所述控制器发送代表运行自清扫模式的信号。
所述控制器接收到所述传感器发出的代表运行自清扫模式的信号,控制室内机1000运行自清扫模式。当自清扫模式运行时,驱动组件400通过传动组件500带动第一卷轴330和第二卷轴340沿相反方向转动,以驱动滤网210沿预定轨迹运动,第一清洁刷320可以与滤网210的不同区域相对设置,并对与自身相对设置的滤网210区域进行清扫。
当第一卷轴330和第二卷轴340沿相反方向转动时,第一清洁刷320与第一卷轴330抵接,以清除第一卷轴330上卷绕的滤网210上的杂物,使杂物掉落至第一集尘盒350内,实现收集杂物。当第一集尘盒350中的杂物较多时,可以将第一集尘盒350拆下进行清理。
本公开的一些实施例提供另一种室内机100A,如图19所示,室内机100A包括壳体100、室内换热器20、第二风机组件30、至少一个滤网210、至少一个自清扫组件300、至少一个驱动组件400和至少一个传动组件500。
如图20和图21所示,壳体100包括第五板12、第六板13、第七板14和第八板15。第五板12是当室内机安装在室内的墙体上时,远离墙体的一侧的侧板。第六板13是当室内机安装在室内的墙体上时,靠近墙体的一侧的侧板。第七板14和第八板15分别连接第五板12和第六板13,且分别沿垂直于第五板12和第六板13的方向延伸。
例如,第七板14是壳体100的长度方向(即如图20所示的左右方向)上的一侧的侧板,第八板15是壳体100的长度方向上的另一侧的侧板。例如,第七板14是室内机100A左侧的一侧板,第八板15是室内机100A右侧的一侧板。
壳体100包括至少一个进风口110和出风口。壳体100的顶部的一部分敞开,以形成进风口110。例如,如图20所示,壳体100包括两个进风口110,两个进风口110分别设置在壳体100的顶部,且沿壳体100的长度方向间隔开设置。
壳体100的底部的一部分敞开,以形成所述出风口。室内换热器20设置在壳体100内,且被配置为与从进风口110进入的室内空气进行换热。第二风机组件30设置在室内换热器20的远离进风口110的一侧,且被配置为吸入和泵出室内空气。例如,第二风机组件30工作时,风机旋转,将室内空气从进风口110吸入,使室内空气室内换热器20换热,然后将经室内换热器20换热后的室内空气从所述出风口泵出。
可以理解的是,室内空气在第二风机组件30的作用下从进风口110进入壳体100内,并经过滤网210的过滤后进入室内换热器20进行换热。例如,在室内机100A进行制冷时,室内空气在经过与室内换热器20的换热后形成冷风从所述出风口吹向室内。
需要说明的是,第二风机组件30可以将室内空气从进风口110引向室内换热器20,增加从进风口110进入室内换热器20的进风量,并且第二风机组件30可以调节进入室内换热器20的进风量。
滤网210设置在进风口110和室内换热器20之间,并且覆盖进风口110。滤网210被配置为过滤从进风口110进入室内机100A的空气,以防止空气中的杂物进入室内机100A。
例如,室内机100A运行时,从进风口110进入壳体100内的室内空气先经过滤网210,在被滤网210过滤后进入室内换热器20,以防止室内空气中的杂物进入室内换热器20,避免杂物在室内换热器20上堆积形成堵塞,而降低室内换热器20的换热效率。经过室内换热器20的换热后的室内空气在第二风机组件30的作用下从所述出风口吹出。
自清扫组件300设置在壳体100内,被配置为清扫附着在滤网210上的杂物。驱动组件400设置在壳体100上,传动组件500设置在壳体100内。驱动组件400被配置为驱动传动组件500转动。传动组件500分别连接自清扫组件300和驱动组件400,且被配置为在驱动组件400的驱动下,带动自清扫组件300运动,以使自清扫组件300清扫附着于滤网210上的杂物,从而实现维持室内机100A制冷或制热的效率。
在一些实施例中,如图31所示,自清扫组件300包括第二基座51、第四卷轴53、第三卷轴52、清洁刷组件54和第二集尘盒55。第二基座51设置在壳体100内,且靠近第五板12。第二基座51包括基座本体511A和第二支架512。第二支架512的一侧与基座本体511A的靠近第六板13的一侧连接,且沿壳体100的厚度方向(即如图20所示的前后方向)延伸。第二支架512被配置为承载滤网210。滤网210设置在第二支架512上,且可以在第二支架512上沿预定的轨迹运动。
第四卷轴53、第三卷轴52和清洁刷组件54与基座本体511A转动连接,且第四卷轴53、第三卷轴52和清洁刷组件54分别沿壳体100的长度方向延伸。第四卷轴53与第三卷轴52间隔开设置,且大致平行。滤网210的一端连接第四卷轴53,另一端连接第三卷轴52。滤网210卷绕在第四卷轴53和第三卷轴52中的至少一者的外周,且滤网210张紧于第四卷轴53与第三卷轴52之间。清洁刷组件54靠近第三卷轴52设置,且被配置为在第三卷轴52收卷滤网210或放卷滤网210的过程中清扫滤网210上的杂物。
自清扫组件300还包括清扫腔56。基座本体511A内限定出清扫腔56。清扫腔56包括第四开口563和第五开口564。清扫腔56的顶部敞开,以形成第四开口563,清扫腔56的底部敞开,以形成第五开口564。第四卷轴53位于第四开口563的上方,第三卷轴52位于第四开口563处,清洁刷组件54位于清扫腔56内。第二集尘盒55设置在第五开口564之下,且被配置为容纳清洁刷组件54从滤网210上清扫下的杂物。
在一些实施例中,第四卷轴53和第三卷轴52沿相反的方向转动。在自清扫组件300清扫的过程中,滤网210在第三卷轴52上收卷,且在第四卷轴53上放卷,或者,滤网210在第三卷轴52上放卷,且在第四卷轴53上收卷。清洁刷组件54的至少部分与滤网210接触,并且随着滤网210的收卷和放卷,清洁刷组件54与滤网210产生相对运动。清洁刷组件54可以与滤网210的不同区域相对设置,并可以对滤网210的不同区域进行清扫。滤网210上的杂物,经由清洁刷组件54清扫至第二集尘盒55内。
在一些实施例中,如图25所示,清洁刷组件54包括清洁刷基座541、第三清洁刷542和至少一个弹性件543。第三清洁刷542设置在清洁刷基座541上。清洁刷基座541包括第三安装部5411和第四安装部5412。第三安装部5411设置在第四安装部5412上,且与第四安装部5412连接。至少一个弹性件543中的任一个弹性件543的一端与第三安装部5411抵接,另一端与第四安装部5412抵接。
例如,弹性件543为弹簧。第三清洁刷542设置在第三安装部5411的远离第四安装部5412的一侧。当第三清洁刷542与第三卷轴52抵接时,第三卷轴52向第三清洁刷542施加力,即向第三安装部5411施加力,使第三安装部5411压缩弹性件543。
在一些实施例中,室内机100A的清洁刷包括第三清洁刷542。
由于第四安装部5412沿壳体100的高度方向(即如图20所示的上下方向)是不动的,因此,弹性件543会向第三安装部5411施加大小相同、方向相反的弹力,以使第三清洁刷542向第三卷轴52施加力,从而可以使第三清洁刷542与第三卷轴52弹性抵接。清洁刷基座541通过弹性件543,使第三清洁刷542与第三卷轴52抵接,有利于实现第三卷轴52或者清洁刷基座541在转动过程中,第三清洁刷542始终与第三卷轴52抵接,提高第三清洁刷542对第三卷轴52上卷绕的滤网210的清洁能力。同时,避免第三卷轴52与第三清洁刷542之间硬性接触导致第三清洁刷542的过度磨损,延长第三清洁刷542的使用寿命。
可以理解的是,第三清洁刷542通过弹性件543与第三卷轴52抵接,当第四卷轴53和第三卷轴52沿相反方向转动时,第三清洁刷542可以与第三卷轴52抵接,并清扫运动至抵接部位的滤网210,使从滤网210上刷除的杂物掉落在第二集尘盒55内实现对杂物的收集。由于第三卷轴52转动的过程中会产生振动或者径向跳动,而弹性件543的弹性有利于提高第三清洁刷542与第三卷轴52抵接的稳定性,避免第三卷轴52与第三清洁刷542之间硬性接触。
例如,当室内机100A工作一段时间后,随着室内空气在第二风机组件30的作用下不断进入室内换热器20,并被室内换热器20换热后送向室内。进入室内换热器20的室内空气经滤网210过滤后,室内空气中的杂物会在滤网210的表面上堆积,使滤网210上附着的杂物增加,影响滤网210的过滤效果和进风效果。
当滤网210上附着的杂物较多时,室内机100A可以运行自清扫模式,以清扫滤网210上附着的杂物,使滤网210保持过滤能力,从而提高室内机100A制冷或制热的效率。当室内机100A运行自清扫模式时,第四卷轴53和第三卷轴52转动,以使滤网210在第四卷轴53上收卷,且在第三卷轴52上放卷,或者,滤网210在第四卷轴53上放卷,且在第三卷轴52上收卷。滤网210在第四卷轴53和第三卷轴52的作用下相对于第三清洁刷542运动,使得第三清洁刷542与滤网210的不同区域相对设置,并对滤网210的不同区域进行清扫。
在一些实施例中,如图21和图26所示,第二集尘盒55包括集尘盒本体551和第四孔553。第四孔553设置在集尘盒本体551的沿壳体100长度方向的一端。壳体100还包括定位件,所述定位件设置在壳体100的沿长度方向的一侧的侧板上。第二集尘盒55与壳体100通过第四孔553和所述定位件的配合卡接,以实现第二集尘盒55与壳体100的可拆卸链接。当需要清扫第二集尘盒55内的杂物时,可以通过第四孔553和所述定位件将第二集尘盒55从壳体100上拆下,以清理第二集尘盒55内的杂物。
如图26所示,第二集尘盒55还包括挡板552。挡板552设置在集尘盒本体551的前侧。挡板552的一端连接集尘盒本体551,挡板552的另一端沿壳体100的高度方向(即如图20所示的上下方向)向上延伸。挡板552被配置为在第二集尘盒55与第二基座51装配时,密封第二集尘盒55的前侧与第二基座51前表面侧之间的间隙,以避免第二集尘盒55内的杂物从所述间隙中溢出。
在一些实施例中,如图25所示,清洁刷组件54还包括第三腔544。第四安装部5412的朝向第三清洁刷542的一侧敞开,第三安装部5411设置在第二安装部5412的敞开的一侧。第三安装部5411与第四安装部5412共同限定出第三腔544。弹性件543设置在第三腔544内。由于弹性件543的两端分别与连接第三安装部5411和第四安装部5412抵接,因此,当第三安装部5411在被挤压时,第三安装部5411可以朝向第四安装部5412运动。这样,在清洁刷组件54中设置第三腔544,有利于弹性件543的安装,避免弹性件543脱出清洁刷基座541。
在一些实施例中,如图25所示,清洁刷组件54还包括至少一个定位柱545。至少一个定位柱545中的任一个定位柱545设置在第三安装部5411和第四安装部5412中的任一者上。弹性件543套设在任一个定位柱545上。
以清洁刷组件54包括两个定位柱545和两个弹性件543,且两个定位柱545设置在第 四安装部5412上为例,两个定位柱545分别设置在第四安装部5412的沿壳体100的长度方向的两端。弹性件543分别套设在定位柱545上。这样,在清洁刷组件54中设置定位柱545,有利于实现弹性件543的限位和安装,使弹性件543沿壳体100的高度方向运动,从而使得第三安装部5411带动第三清洁刷542相对第四安装部5412运动。
在一些实施例中,如图25所示,清洁刷基座541还包括至少一个第四卡槽5414和至少一个第五卡扣部5415。至少一个第四卡槽5414设置在第三安装部5411的沿壳体100的宽度方向的两侧壁中的至少一者上。至少一个第五卡扣部5415设置在第四安装部5412的沿壳体100的宽度方向的两侧壁中的至少一者上。第五卡扣部5415和第四卡槽5414配合卡接,以使第三安装部5411与第四安装部5412连接。第五卡扣部5415卡接在第四卡槽5414内时,第五卡扣部5415可以沿壳体100的高度方向在第四卡槽5414内运动。
例如,在至少一个第三安装部5411包括多个第四卡槽5414的情况下,多个第四卡槽5414间隔开设置在第三安装部5411的沿壳体100的宽度方向的两侧壁上。与多个第四卡槽5414相对应的,第四安装部5412的沿壳体100的宽度方向的两侧壁上设有多个第五卡扣部5415,且多个第五卡扣部5415沿壳体100的长度方向间隔开设置。
在第三安装部5411与第四安装部5412配合卡接时,多个第四卡槽5414与多个第五卡扣部5415配合卡接,以实现第三安装部5411和第四安装部5412的安装。
例如,第四卡槽5414的沿壳体100的高度方向的长度大于第五卡扣部5415的沿壳体100的高度方向的长度,以使第三安装部5411可以沿壳体100的高度方向相对于第四安装部5412运动。
可以理解的是,当第三清洁刷542与第三卷轴52抵接时,第三安装部5411朝向第四安装部5412运动。当第三清洁刷542与第三卷轴52分离时,第三安装部5411朝向远离第四安装部5412的方向运动。这样,第三安装部5411和第四安装部5412之间通过第四卡槽5414和第五卡扣部5415配合卡接,有利于提高第三安装部5411和第四安装部5412的装配效率,简化清洁刷基座541的结构,提高第三安装部5411和第四安装部5412装配的稳定性。
而且,第五卡扣部5415卡接在第四卡槽5414内时,第五卡扣部5415相对于第四卡槽5414可运动,有利于实现第三安装部5411相对于第四安装部5412的运动,使第三清洁刷542与第三卷轴52抵接,提高第三清洁刷542清扫滤网210的效率。
在一些实施例中,如图24至图26所示,第三安装部5411包括第一侧部5416、第二侧部5417和第二连接部5413。第二连接部5413的沿壳体100的厚度方向的两端分别连接第一侧部5416和第二侧部5417的上侧,第一侧部5416和第二侧部5417的下侧沿壳体100的高度方向朝向第四安装部5412延伸。第一侧部5416、第二侧部5417和第二连接部5413共同构成第三安装部5411。
第一侧部5416和第二侧部5417朝向第四安装部5412延伸。弹性件543的一端与第二连接部5413抵接,弹性件543的另一端套设在第四安装部5412上设置的定位柱545上。第一侧部5416和第二侧部5417通过第四卡槽5414和第五卡扣部5415的配合卡接,与第四安装部5412连接。当装配第三安装部5411与第四安装部5412时,第一侧部5416和第二侧部5417位于第四安装部5412的沿壳体100的厚度方向的两个侧壁的外侧,以形成对第四安装部5412的限位,避免弹性件543脱出。
清洁刷基座541中设置第一侧部5416、第二侧部5417和第二连接部5413以构成第三安装部5411,使第三安装部5411具有良好的结构强度,有利于第三安装部5411与第三清洁刷542安装,使第三清洁刷542的安装更为牢固,避免第三清洁刷542从清洁刷基座541上脱落。
在一些实施例中,如图25和图26所示,自清扫组件300还包括安装槽57。安装槽57设置在第二连接部5413的远离第四安装部5412的一侧。第三清洁刷542设置在安装槽57内。安装槽57的底面与第三清洁刷542的靠近第三卷轴52的一侧表面平齐,呈弧形,以使第三清洁刷542在与第三卷轴52抵接时,可以实现对滤网210的清扫,以及使由清扫产生的杂物可以从第三清洁刷542的表面落入清扫腔56内。这样,在自清扫组件300中 设置安装槽57,有利于第三清洁刷542的安装,提高第三清洁刷542安装的稳定性,增加第三安装部5411对清洁刷542的限位。
在一些实施例中,如图23、图26和图27所示,自清扫组件300与两个传动组件500连接。驱动组件400与两个传动组件500中的任一个连接。两个传动组件500沿壳体100的长度方向分别设置在自清扫组件300的两端。驱动组件400沿壳体100的长度方向设置在壳体100的一端。
传动组件500包括第一齿轮71、第二齿轮72和第三齿轮73。第一齿轮71与第二齿轮72啮合。在两个传动组件500中,两个第一齿轮71分别设置在第四卷轴53的两端,两个第二齿轮72分别设置在第三卷轴52的两端,两个第三齿轮73分别设置在清洁刷基座541的两端。
驱动组件400包括第一驱动电机61和第二驱动电机62。第一驱动电机61与第一齿轮71和第二齿轮72中的一者连接,且被配置为驱动第一齿轮71和第二齿轮72中的任一者转动。第二驱动电机62与第三齿轮73连接,且被配置为驱动第三齿轮73转动。
以第一驱动电机61与第二齿轮72连接为例,当自清扫组件300运行自清扫模式时,第一驱动电机61驱动第二齿轮72沿第一方向转动,以带动第三卷轴52沿所述第一方向转动。同时第二齿轮72还带动第一齿轮71沿第二方向转动,进而带动第四卷轴53沿所述第二方向转动。第二驱动电机62驱动第三齿轮73转动,以带动清洁刷基座541转动。
需要说明的是,所述第一方向与所述第二方向相反。当第四卷轴53沿所述第二方向转动,并放卷滤网210时,第三卷轴52沿所述第一方向转动,并收卷滤网210。
这样,在第四卷轴53和第三卷轴52的作用下,张紧在第四卷轴53和第三卷轴52之间的滤网210沿预定轨迹运动,使得第三清洁刷542与滤网210发生相对运动,以实现第三清洁刷542对滤网210的清扫。
可以理解的是,第四卷轴53的两端分别与第一齿轮71连接,第四卷轴53通过第一齿轮71实现与第二基座51的转动连接。第三卷轴52的两端分别与第二齿轮72连接,第三卷轴52通过第二齿轮72实现与第二基座51的转动连接。清洁刷基座541的两端分别与第三齿轮73连接,清洁刷基座541通过第三齿轮73实现与第二基座51的转动连接。
在一些实施例中,如图22至图26所示,室内机100A包括两个自清扫组件300、两个驱动组件400和四个传动组件500。一个自清扫组件300、一个驱动组件400和两个传动组件500构成自清扫装置,即室内机100A包括两个所述自清扫装置。两个自清扫组件300沿壳体100的长度方向间隔开设置。
以一个所述自清扫装置为例,自清扫组件300与两个传动组件500连接,且两个传动组件500分别设置在自清扫组件300的两端。驱动组件400与靠近壳体100的侧壁的传动组件500连接。驱动组件400驱动传动组件500转动,以带动自清扫组件300转动。
由于两个自清扫组件300的两端分别设有传动组件500,因此,将自清扫组件300与壳体100安装时可以不用区分左右,有利于提高自清扫组件300的安装效率。
在一些实施例中,如图27所示,驱动组件400还包括壳体部63和折弯部64。壳体部63与壳体100连接。折弯部64设置在壳体部63的沿壳体100的宽度方向的一侧,折弯部64的自由端沿壳体100的长度方向朝向第二基座51延伸。折弯部64、壳体部63和第二基座51限定出容纳空间,第一驱动电机61和第二驱动电机62设置在所述容纳空间内。这样,有利于降低水气或者空气中的灰尘进入所述容纳空间内,从而避免第一驱动电机61和第二驱动电机62的损坏,使得驱动组件400的使用寿命延长。
在一些实施例中,如图26和图27所示,第二基座51还包括两个端盖514和连接板516。两个端盖514分别设置在第二基座51的沿壳体100的长度方向的两端。连接板516连接两个端盖514,且位于两个端盖的远离第六板13的一侧上。连接板516包括握持部5161,握持部5161设置在连接板516的顶部。如图28所示,握持部5161包括多个凹槽,所述凹槽沿壳体100的高度方向朝向第二集尘盒55凹进。所述多个凹槽在连接板516上沿壳体100的长度方向连续设置。这样,有利于用户在拆装自清扫组件300时握持自清扫组件300,从而提高自清扫组件300的装配效率。
在一些实施例中,如图26和图27所示,第二基座51还包括基座前盖513。基座前盖513设置在壳体100的前侧,且位于连接板516的下方。基座前盖513的下端与基座本体511A可拆卸地连接。基座前盖513的上端与基座本体511A转动连接。
基座前盖513被配置为打开或关闭清扫腔56的前侧。这样,有利于实现对清扫腔56内的第三清洁刷542的清扫,提高第三清洁刷542的工作效率,并且在自清扫组件300内部的部件出现故障时,可以通过基座前盖513对自清扫组件300内部的部件进行维护,以及有利于自清扫组件300内部的部件(如第四卷轴53、第三卷轴52和第三清洁刷542等)的安装和拆卸。
例如,随着自清扫组件300的长时间的工作,清洁刷542刷除滤网210上的杂物的能力降低。当需要对第三清洁刷542进行清扫时,可以通过打开基座前盖513,实现对清扫腔56内的第三清洁刷542进行清理。
在一些实施例中,如图26所示,基座前盖513包括转轴5131。转轴5131设置在基座前盖513的沿壳体100长度方向的两端。基座本体511A还包括转轴孔,所述转轴孔设置在基座本体511A上。转轴5131与所述转轴孔配合卡接,以实现基座前盖513与基座本体511A的转动连接。这样,打开基座前盖513时,基座前盖513的下侧向上翻转,以实现打开清扫腔56的前侧。
在一些实施例中,如图25和图26所示,清洁刷组件54还包括至少一个第二限位部546。至少一个第二限位部546设置在清洁刷基座541的沿壳体100的长度方向的一端。例如,至少一个第二限位部546包括一个第二限位部546,一个第二限位部546设置在第四安装部5412的沿壳体100的长度方向的一端。例如,至少一个第二限位部546包括两个第二限位部546,两个第二限位部546分别设置在第四安装部5412的沿壳体100的长度方向的两端。
如图28所示,清洁刷组件54还包括止挡部547。止挡部547设置在清扫腔56的内壁上。
第二限位部546被配置为与止挡部547抵接,以限定清洁刷组件54的转动角度。当清洁刷组件54工作,且第二限位部546与止挡部547抵接时,第三清洁刷542与第三卷轴52抵接,并清扫处于抵接处的滤网210上的杂物。在清洁刷组件54中设置第二限位部546和止挡部547,有利于限位清洁刷组件54的转动角度,使得第三清洁刷542在第三清洁刷基座541的作用下可以精确地与第三卷轴52抵接,实现对滤网210的清理,并降低第三清洁刷542与滤网210抵接时出现偏移的可能性。
例如,至少一个第二限位部546包括第一限位凸起5461和第二限位凸起5462。第一限位凸起5461和第二限位凸起5462设置在第四安装部5412的沿壳体100的长度方向的端部,且沿第四安装部5412的径向对称设置。
第二限位部546被配置为转动至第一位置,以使第一限位凸起5461与止挡部547抵接,从而使得第三清洁刷542与第三卷轴52不接触,以及,第二限位部546转动至第二位置,以使第二限位凸起5462与止挡部547抵接,从而使得第三清洁刷542与第三卷轴52抵接。
例如,当清洁刷组件54沿顺时针方向转动,且第二限位部546转动至所述第一位置时,第一限位凸起5461与止挡部547抵接,止挡部547限定第二限位部546继续转动,第三清洁刷542与第三卷轴52不接触,第一限位凸起5461位于第二限位凸起5462的下方,第三清洁刷542位于清洁刷基座541中心轴线的下方。
当清洁刷组件54沿逆时针方向转动,且第二限位部546转动至所述第二位置时,第二限位凸起5462与止挡部547抵接,止挡部547限定第二限位部546继续转动,第三清洁刷542与第三卷轴52抵接,并清扫处于抵接处的滤网210上的杂物。
第二限位凸起5462与止挡部547的抵接,使得第三清洁刷542与第三卷轴52抵接,有利于避免第三清洁刷542在惯性的作用下与滤网210出现错位,降低第三清洁刷542的清洁效果。
在一些实施例中,如图28所示,止挡部547包括第一止挡面5471和第二止挡面5472。 当第二限位部546转动至所述第一位置时,第一限位凸起5461与第一止挡面5471抵接,第三清洁刷542与第三卷轴52不接触。当第二限位部546转动至所述第二位置时,第二限位凸起5462与第二止挡面5472抵接,第三清洁刷542与第三卷轴52抵接,以刷除滤网210上的杂物。
第一止挡面5471的一端和第二止挡面5472的一端连接,且第一止挡面5471位于第二止挡面5472的下方。第一止挡面5471的另一端沿壳体100的厚度方向朝向靠近第六板13的方向,且向下倾斜延伸。第二止挡面5472的另一端沿壳体100的厚度方向朝向靠近第六板13的方向,且向上倾斜延伸。
例如,当清洁刷基座541沿顺时针方向转动,且第二限位部546转动至所述第一位置时,第一限位凸起5461与第一止挡面5471抵接。第一止挡面5471限定第一限位凸起5461继续转动,第三清洁刷542与第三卷轴52不接触,第一限位凸起5461位于第二限位凸起5462的下方,第三清洁刷542位于清洁刷基座541中心轴线的下方。
在清洁刷基座541沿逆时针方向转动,且第二限位部546从所述第一位置转动至所述第二位置的过程中,第一限位凸起5461从与第一止挡面5471抵接变成分离,然后第二限位凸起5462与第二止挡面5472抵接,使得第三清洁刷542与第三卷轴52抵接,以清扫滤网210。
这样,止挡部547中设置第一止挡面5471和第二止挡面5472,有利于第一限位凸起5461和第二限位凸起5462与止挡部547的抵接,提高第二限位部546与止挡部547抵接的稳定性和可靠性,减小清洁刷组件54的转动误差。
在一些实施例中,如图24、图26和图27所示,自清扫组件300还包括清扫件59。清扫件59设置在基座前盖513的靠近清扫腔56的一侧。例如,清扫件59与基座前盖513之间可通过粘结剂或者卡接结构连接。清扫件59设置在清扫腔56的与止挡部547相对的一侧的侧壁上。当第二限位部546在所述第一位置和所述第二位置之间来回转动时,清扫件59被配置为清扫第三清洁刷542上的杂物。
例如,止挡部547设置在清扫腔56的后壁,清扫件59设置在清扫腔56的前壁。当滤网210上的杂物较多,需要对滤网210进行清扫时,第二限位部546从所述第一位置转动至所述第二位置的过程中,第三清洁刷542与第三卷轴52抵接,以清扫滤网210。在第二限位部546从所述第一位置转动至所述第二位置的过程中,清扫件59可以与第三清洁刷542接触,以清扫第三清洁刷542上的杂物,使第三清洁刷542处于较干净的状态。
这样,当第二限位凸起5462再次与止挡部547抵接时,被清扫件59清扫过的第三清洁刷542可以更好地清扫滤网210上的杂物,提高清洁刷组件54对滤网210的清洁效果。
在一些实施例中,如图24和图26所示,基座前盖513还包括避让段5132和延伸段5133。避让段5132位于两个端盖514之间,避让段5132朝向远离第三清洁刷542的中心轴线的方向凸出。转轴5131连接在避让段5132的远离第三清洁刷542的一侧。延伸段5133沿壳体100的高度方向延伸。延伸段5133的上端与避让段5132的下端连接,延伸段5133的下端与第二集尘盒55配合卡接。
基座前盖513为清扫腔56的一部分,被配置为在清扫腔56的前侧形成对清扫腔56的封闭。避让段5132位于延伸段5133的上方,且在壳体100的厚度方向上避让段5132与第三清洁刷542相对。转轴5131设置在避让段5132的远离第三清洁刷542的一侧,当基座前盖513与基座本体511A配合卡接时,延伸段5133的沿壳体100的高度方向的远离避让段5132的一端与第二集尘盒55的上部配合卡接。也即第二集尘盒55在与基座本体511A装配时,第二集尘盒55的上部与基座前盖513配合卡接,以形成在基座本体511A的前侧和下侧对清扫腔56进行密封。
例如,如图24所示,避让段5132形成为朝向远离第三清洁刷542的中心轴线的方向凸出的弧形,避让段5132的中心线与第三清洁刷542的中心轴线重合。这样,在基座前盖513与基座本体511A配合卡接时有利于避免基座前盖513与第三清洁刷542产生干涉。并且,有利于增加对第二基座51空间的利用率,限定基座前盖513与第三清洁刷542之间的间距,有利于使第三清洁刷542转动过程中产生的灰尘颗粒物等沿避让段5132集中 掉落在第二集尘盒55内,减小清扫腔56内部的扬尘,减小自清扫组件300的体积。
在一些实施例中,如图24所示,第二基座51还包括基座后盖515。基座后盖515设置在两个端盖514之间,且基座后盖515沿壳体100的厚度方向设置在清扫腔56的后侧。基座后盖515与基座前盖513相对,基座后盖515与基座本体511A转动连接。基座后盖515包括连接槽,所述连接槽设置在基座后盖515上。所述连接槽的朝向清洁刷组件54的一侧敞开。所述连接槽内设有密封件。
当关闭基座后盖515,以关闭清扫腔56的后侧时,所述密封件被配置为密封基座后盖515与第三卷轴52之间的间隙。当打开基座后盖515,以打开清扫腔56的后侧时,所述密封件与第三卷轴52彼此间隔开。也即,当基座后盖515与基座本体511A连接时,基座本体511A朝向第三卷轴52的一侧上设有所述连接槽,且所述连接槽内设有所述密封件,所述密封件与所述连接槽可拆卸地连接。
所述密封件的后侧位于所述连接槽内,所述密封件的前侧伸出所述连接槽,且与第三卷轴52抵接。例如,所述密封件为具有较高的回弹性的由聚氨酯发泡过的海绵。
这样,在基座后盖515上设置所述连接槽,在所述连接槽内设置所述密封件,可以使清扫腔56的第四开口563处通过所述密封件与第三卷轴52抵接,以形成对第四开口563处的密封,有利于避免清扫腔56内的灰尘流向第二风机组件30或者室内换热器20,延长室内机100A的使用寿命。
在一些实施例中,如图24所示,第五开口564的宽度沿壳体100的高度方向从上到下倾斜设置,即第五开口564的横截面积沿壳体100的高度方向从上到下减小。第五开口564位于清扫腔56的底部。第五开口564的靠近清扫腔56的一端开口较大,靠近第二集尘盒55的一端开口较小。
当第三清洁刷542清扫滤网210上的杂物时,部分杂物会由于第三清洁刷542转动时产生的离心力飞溅到清扫腔56的内壁上。将第五开口564沿壳体100的高度方向从上到下口径减小,使灰尘流向第二集尘盒55,避免清扫腔56的侧壁出现死角导致灰尘的聚集。
在一些实施例中,如图24所示,清扫腔56还包括第一延伸段561和第二延伸段562。第一延伸段561和第二延伸段562设置在清扫腔56的下部。第一延伸段561连接在清扫腔56的前壁上,第二延伸段562连接在清扫腔56的后壁上,第一延伸段561和第二延伸段562之间限定出第五开口564。沿壳体100的高度方向从上到下、第一延伸段561和第二延伸段562之间的距离减小。
例如,第一延伸段561的一端与清扫腔56的前壁的底部连接,且位于第三清洁刷542的下方。第一延伸段561的另一端朝向第二集尘盒55倾斜延伸。第二延伸段562的一端与清扫腔56的后壁的底部连接,且位于第三清洁刷542的下方。第二延伸段562的另一端朝向第二集尘盒55倾斜延伸。
第一延伸段561和第二延伸段562朝向靠近彼此的方向倾斜延伸。也即第一延伸段561和第二延伸段562的另一端同时朝向第二集尘盒55的中心倾斜延伸,以使第一延伸段561和第二延伸段562构造为漏斗形的第五开口564。
此外,第一延伸段561和第二延伸段562的另一端与清扫腔56的底部平齐,以避免第一延伸段561和第二延伸段562对第二集尘盒55的安装产生干涉。
这样,沿壳体100的高度方向从上到下,第一延伸段561和第二延伸段562之间的距离减小,有利于使第三清洁刷542刷除的杂物落入第二集尘盒55中,降低杂物在清扫腔56内部或者第五开口564处积存的可能性,以及降低杂物落入第二集尘盒55以外区域的风险。并且,第一延伸段561和第二延伸段562整体位于第三清洁刷542的下方,有利于引导从滤网210上清扫下的杂物落入第二集尘盒55内,避免杂物在清扫腔56内堆积。
在一些实施例中,如图24和图26所示,自清扫组件300还包括插接部58。插接部58设置在连接板516上,且可以相对于连接板516沿壳体100的长度方向运动。当自清扫组件300安装于壳体100上时,插接部58沿壳体100的长度方向运动至一部分伸出第二基座51的端部,并与壳体100配合卡接,以实现自清扫组件300的安装。在需要拆卸自清扫组件300时,拨动插接部58,使插接部58沿壳体100的长度方向朝向第二基座51的中心 移动,以将插接部58与壳体100分离,实现自清扫组件300从壳体100上的拆卸。
在自清扫组件300中设置插接部58,有利于安装和拆卸自清扫组件300,提高安装和拆卸自清扫组件300的效率。
图29为根据一些实施例的一种空调器的框图,如图29所示,控制器80是指可以根据指令操作码和时序信号,产生操作控制信号,指示空调器1执行控制指令的装置。在一些实施例中,控制器80与室外机1001、室内机1000、壳体100、滤网210以及自清扫组件300耦接,且被配置为控制各部件工作,使得空调器1中各个部件运行,以实现空调器1的各预定功能。
例如,控制器80被配置为:控制空调器1上电并获取空调器1的累计运行时长。当空调器1的累计运行时长大于第一预设时间阈值、小于或等于第二预设时间阈值,且空调器1处于停机状态时,控制自清扫组件300执行清扫功能,空调器1的清扫功能执行完毕后,控制空调器1进入下一清扫周期。
在本公开一些实施例中,提供一种控制方法,应用于控制器80上。如图30所示,在一些实施例中,该控制方法包括S10至S15。
S10、空调器1上电。
S11、获取空调器1的累计运行时长ton_add
在空调器1上电且开机运行后,即进入第一个清扫周期,控制器80获取并统计空调器1的运行状态信息,来执行相应的信息处理和控制指令下发的操作。
在一些实施例中,空调器1的运行状态信息包括空调器1的连续运行时长ton、连续停机时长toff、累计运行时长ton_add和累计停机时长toff_add,还可以包括空调器1的压缩机的运行频率、运行转速或室内风机的运行转速等。
需要说明的是,连续运行时长ton是指距离当前的时间差最小的一次连续运行时长;连续停机时长toff是指距离当前的时间差最小的连续关机时长;累计运行时长ton_add是指在当前的清扫周期内,累计的开机运行时长。例如,空调器1进入当前的清扫周期之后,连续运行了8小时,在用户控制下关机了3小时,又重新开机运行了12小时。此时,连续运行时长ton为12小时,连续停机时长toff为3小时,累计运行时长toff_add为8+12=20小时。
S12、判断累计运行时长是否大于第一预设时间阈值t1,且小于第二预设时间阈值t2。若是,则执行S13,若否,则继续执行S11。
在一些实施例中,空调器1的运行状态信息包括空调器1的累计运行时长。此时,预先设置第一预设时间阈值t1和第二预设时间阈值t2,第一预设时间阈值t1和第二预设时间阈值t2用于表征空调器1处于累计运行状态的时长。若确定空调器1的累计运行时长ton_add满足t1<ton_add<t2,则控制器80判定空调器1需要对滤网210进行清洗。
在一些实施例中,第一预设时间阈值t1和第二预设时间阈值t2例如为12~72小时,且第一预设时间阈值t1小于第二预设时间阈值t2。例如,设置第一预设时间阈值t1为24小时,设置第二预设时间阈值t2为32小时,在当前的清扫周期内,用户控制空调器1启动,并且空调器1连续运行了8小时,再停止运行n小时,之后又开机并连续运行了12小时,再停止运行n小时,之后又开机并连续运行了6小时后关机。此时,控制器80统计得到累计运行时长ton_add=8小时+12小时+6小时=26小时,满足t1<ton_add<t2,此时,则继续执行S13。
S13、判断空调器1是否处于停机状态,若是,则执行S14,若否,则继续执行S11。
在累计运行时长ton_add满足t1<ton_add<t2的情况下,若控制器80确定空调器1当前处于停机状态,则可以判定空调器1满足预设的自动清扫条件,此时,控制器80控制自清扫组件300启动运行,对滤网210进行清扫。其中,n>0。
S14、控制自清扫组件300执行清扫功能。
S15、空调器1进入下一个清扫周期。
控制器80获取到清扫功能执行完毕后,控制器80控制空调器1重新启动,并 继续按照清扫前的运行状态运行,并且,控制器80将当前周期的运行状态信息清零,并进入下一个清扫周期的统计和控制。
需要说明的是,控制器80执行不同的清扫周期所需要的时间可以相同也可以不同。
这样,在一些实施例中,控制器80通过获取空调器1的运行状态信息以及空调器1的开机或关机状态来判断空调器1是否满足预设的清扫条件,以实现对滤网210的清扫,避免了用户取出并清洗滤网210的操作,提高了清洁滤网210的效率。并且,还可以避免由于用户不及时清洗滤网210而导致的滤网210上的灰尘堆积,影响空调器1的出风量,进而影响空调器1运行性能的问题,保证了空调器1的正常运行。
如图31所示,在一些实施例中,在确定累计运行时长ton_add在(t1,t2)外的情况下,在S12之后,该控制方法还包括S21至S22。
S21、判断累计运行时长ton_add是否大于或等于第二预设时间阈值t2。若是,则执行S22,若否,则继续执行S11。
在当前清扫周期内,控制器80在检测到空调器1的累计运行时长ton_add大于第二预设时间阈值t2,即,满足ton_add≥t2的情况下,则无论当前空调器1是否处于停机状态,均判定空调器1满足预设的清扫条件。此时,控制器80控制空调器1停机,并控制自清扫组件300启动运行,对滤网210进行清扫,待清扫功能执行完毕后,重新控制空调器1启动运行,并回到清扫前的运行状态,此时,空调器1进入下一清扫周期。例如,设置第五预设时间阈值t5为32小时。在当前清扫周期内,用户控制空调器1启动,并且空调器1连续运行了8小时,再停止运行n小时,之后又开机并连续运行了12小时,再停止运行n小时,之后又开机并连续运行了超过12小时。此时,控制器80统计得到累计运行时长ton_add=8小时+12小时+12小时=32小时,满足ton_add≥t2,则判定空调器1满足预设的清扫条件,控制自清扫组件300启动运行,以对滤网210进行清扫。
S22、控制空调器1停机。
这样,在空调器1已经累计运行了更长的一段时间并且未对滤网210进行清扫的情况下,可以强制中断空调器1的运行,启动自清扫组件300对滤网210进行清扫,避免了用户不及时清洗导致滤网210堆积大量灰尘,影响空调器1的出风量,进而影响空调器1的运行性能的问题,保证空调器1的正常运行。
如图32所示,在一些实施例中,空调器1的运行状态信息包括空调器1的连续运行时长ton,此时,在S10之后,该控制方法还包括S31至S32。
S31、获取空调器1的连续运行时长ton
S32、判断连续运行时长ton是否大于第三预设时间阈值t3,若是,则执行S22,若否,则继续执行S31。
需要说明的是,第三预设时间阈值t3用来表征连续运行时长ton的大小。当连续运行时长ton大于第三预设时间阈值t3时,即,满足ton>t3时,控制器80判定空调器1满足预设的清扫条件。此时,控制器80控制自清扫组件300启动,对滤网210进行清扫。
第三预设时间阈值t3为预先设置的值,第三预设时间阈值t3的取值范围例如为[12h,72h]。例如,设置t3为24h。在当前清扫周期内,用户控制空调器1启动运行,并且空调器1连续运行了25h,则当前连续运行时长ton为25h,大于第三预设时间阈值t3,此时,判定满足预设的清扫条件。
在一些实施例中,在控制器80判定满足预设的清扫条件的情况下,先控制空调器1停机,再控制自清扫组件300启动,对滤网210进行清扫,待清扫功能执行完毕后,重新控制空调器1启动运行,回到清扫前的运行状态。然后,假设空调器1在重新启动后又连续运行了25小时,则再次控制空调器1停机,并控制自清扫组件300启动,对滤网210进行清扫,待清扫功能执行完毕后,重新控制空调器1启动并回到清扫前的运行状态。
这样,可以有效避免滤网210堆积大量灰尘,影响空调器1的出风量,进而影响空调 器1的运行性能,保证空调器1的正常运行。
需要说明的是,如图33所示,在一些实施例中,控制器80在执行控制自清洁组件300执行清扫功能,或控制空调器1停机之前,该控制方法还包括S41。
S41、判断是否满足预设条件。若是,则执行S22或S14,若否,则继续执行S11。
在一些实施例中,预设条件为控制器80允许执行清扫功能的前提条件。
需要说明的是,在一些实施例中,预设条件包括以下至少之一:判断是否接收到关机控制指令;判断当前时间是否处于用户预设时间段外;或,判断当前室内光线强度是否大于预设光线强度阈值。
这样,空调器1在满足预设的清扫条件之后,还需要满足预设条件,才会启动自清扫组件300对滤网210进行清扫,可以满足用户的生活需求,同时,还能避免空调器1处于特殊的运行模式下时,由于强行停机进行清扫的操作降低空调器1的使用寿命。
如图34所示,在一些实施例中,预设条件包括判断是否接收到关机控制指令。此时,S41包括S411。
S411、判断是否接收到关机控制指令。若是,则执行S22或S14,若否,则继续执行S11或S31。
当控制器80判定满足预设的清扫条件时,若确定空调器1处于开机运行状态,但是控制器80未接收到用户输入的关机控制指令,则维持空调器1当前的运行状态不变,且维持自清扫组件300处于关闭状态。若确定控制器80接收到用户输入的关机控制指令,则控制空调器1停机,并控制自清扫组件300启动运行,对滤网210进行清扫。
这样,用户可以控制空调器1关机,避免影响用户对空调器1的正常使用。
如图35所示,在一些实施例中,预设条件包括判断当前时间是否处于预设时间段外。此时,S41包括S412。
S412、判断当前时间是否处于预设时间段外。若是,则执行S22或S14;若否,则继续执行S11或S31。
例如,用户预设时间段为23:00~7:00,此时若确定当前时间处于23:00~7:00时间段内,则维持空调器1原来的状态不变,且维持自清扫组件300处于关闭状态,避免自清扫时发出噪声影响用户需求。若确定时间到了7:00,且空调器1处于开机状态,则控制空调器1停机,并控制自清扫组件300启动运行,对滤网210进行清扫。
需要说明的是,用户可以根据需求设定休息时间段或工作时间段等,且可以根据用户的需求进行调整或取消。
这样,空调器1在用户预设时间段内不对滤网210进行清扫,可以避免执行清扫功能时产生的噪音对用户休息造成影响。
如图29所示,空调器1还包括光线强度检测组件90,光线强度检测组件90设置于空调器1的壳体上,被配置为检测当前室内的光线强度,且光线强度检测组件90与控制器80耦接。此时,如图36所示,S41还包括S413。
S413、判断当前室内光线强度是否大于预设光线强度阈值。若是,则执行S22或S14,若否,则继续执行S11或S31。
若确定当前室内的光线强度大于预设光线强度阈值,则表明当前室内的光线较强,此时若空调器1处于开机状态,则控制空调器1停机,并控制自清扫组件300启动运行,对滤网210进行清扫。若确定当前室内的光线强度小于或等于预设光线强度阈值,则表明当前室内的光线较弱,此时维持空调器1当前的运行状态不变,且维持自清扫组件300处于关闭状态。
需要说明的是,若确定当前室内的光线较强,则认为是白天或开灯状态,判定用户不在休息,可以执行清扫功能。若当前室内光线较弱,则认为是处于夜晚、关灯状态或是窗帘拉上的状态,判定用户正在休息,空调器1维持原来的状态,且不执行清扫功能。
这样,可以避免执行清扫功能时产生的噪音对用户休息造成影响。
如图37所示,在一些实施例中,S14包括S141至S142。
S141、控制驱动组件400沿第一方向旋转,并达到第一预设转动角度。
S142、控制驱动组件400沿第二方向旋转,并达到第二预设转动角度。
其中,第一方向与第二方向相反,第一预设转动角度可以和第二预设转动角度相同,也可以第二预设转动角度不同。
在一些实施例中,当空调器1启动清扫功能时,如图10和图11所示,驱动组件400沿第一方向旋转,带动传动组件500转动,从而带动第一卷轴330和第二卷轴340转动,使滤网210在第一卷轴330上收卷,且在第二卷轴340上放卷,从而使得滤网210张紧在第一卷轴330和第二卷轴340之间,并且相对于第一清洁刷320运动。这样,第一清洁刷320可以对与其相对的滤网210区域进行清扫。当驱动组件400转动达到第一预设转动角度时,表明整个滤网210的全部区域均已经过第一清洁刷320的清扫。然后,再控制驱动组件400沿第二方向转动进行复位。
例如,第一方向为顺时针方向,第二方向为逆时针方向,则驱动组件400沿顺时针方向旋转Y°,带动第一驱动齿轮510沿顺时针方向旋转,并带动第一卷轴330沿顺时针方向旋转,以放卷滤网210。然后,第一从动齿轮510在沿顺时针方向旋转的同时带动第二从动齿轮520沿逆时针方向旋转Y°,从而带动第二卷轴340沿逆时针方向转动,并收卷滤网210。
在一些实施例中,如图30、图33和图34所示,驱动组件400包括第一驱动电机61和第二驱动电机62;传动组件500包括第一齿轮71、第二齿轮72和第三齿轮73。在启动清扫组件后,通过控制第一驱动电机61和第二驱动电机62同时转动,从而带动清洁刷542、第三卷轴52和第四卷轴53的转动。
此时,假设对于第一驱动电机来说,第一方向为顺时针方向,第二方向为逆时针方向,预设的转动角度为X°,那么,控制器80控制第一驱动电机顺时针转动X°,同时控制第二驱动电机逆时针转动X°,以使清洁刷542完成对滤网210的清扫。之后,再控制第一驱动电机逆时针转动X°,同时控制第二驱动电机顺时针转动X°,以使滤网210复位。
这样,在空调器1满足预设的清扫条件以及预设条件时,控制器80通过控制清洁刷、第一卷轴、第二卷轴、第三卷轴、第四卷轴、驱动电机和传动组件的相互配合,来实现对滤网的清扫,有利于提高清扫滤网的效率。
本领域的技术人员将会理解,本发明的公开范围不限于上述具体实施例,并且可以在不脱离本申请的精神的情况下对实施例的某些要素进行修改和替换。本申请的范围受所附权利要求的限制。
