Description

一种线屑清理装置及干衣机

技术领域
本文涉及干衣机技术领域，例如涉及一种线屑清理装置及干衣机。
背景技术
干衣机是用于对衣类物品进行烘干处理的常用生活家电，热泵式干衣机为干衣机的常用类型。热泵式干衣机内设置有空气循环通道，由热泵循环***中的加热器进行过加热的加热空气被送至干衣机的滚筒内对衣类进行烘干，加热空气与湿的衣类物品接触带走水分，湿热空气流通至蒸发器进行除湿，除湿后的空气再次被加热器加热进行循环流通。
由于干衣机在工作过程中，滚筒带动滚筒内的衣物翻转，使滚筒内会有少量衣物线屑产生。滚筒内产生的线屑随着空气循环流通会附着在蒸发器上，尤其会附着在蒸发器进风面的一侧。线屑在蒸发器上的附着会导致蒸发器被线屑堵塞而影响干衣机的烘干时间和烘干效率，从而需要对蒸发器上附着的线屑进行清理，以保证蒸发器的正常有效运行。
相关技术记载了一种干衣机蒸发器线屑清理装置，其在蒸发器上方设置具有容腔的喷水装置，喷水装置底部设有多个用于向蒸发器喷水的喷水孔，喷水孔沿蒸发器迎风面排列。通过泵将水流泵入喷水装置中，使水从喷水孔流出对蒸发器的迎风面进行清洗，可以对蒸发器上附着的线屑进行清理。
但是，相关技术提供的线屑清理装置，由于将喷水装置设置在蒸发器的上端，依靠水流重力作用对蒸发器上的线屑进行清理，当蒸发器上的线屑积累过 多时，有可能导致积累的线屑无法被水流冲刷掉落，从而存在线屑清理不彻底的现象。
发明内容
本文提供了一种线屑清理装置，用以对蒸发器表面的线屑进行彻底有效的清理，保证蒸发器的正常运行。
本文还提供了一种干衣机，能够对干衣机内蒸发器处积累的线屑进行清理，提高干衣机的烘干效率。

下面结合附图和实施例对本文作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本文，而非对本文的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本文相关的部分而非全部结构。
图1为本发明实施例提供的线屑清理装置10的结构示意图，如图1所示，本实施例提供了一种线屑清理装置10，设置在蒸发器20的迎风侧，用于对蒸发器20的迎风面201上积累的线屑进行清理。线屑清理装置10包括安装架、清理组件2、驱动组件1、调节组件3和导向组件4。其中，清理组件2为长条状，且可以沿蒸发器20的长度方向设置；驱动组件1与清理组件2连接，驱动组件1配置为带动清理组件2沿蒸发器20的高度方向上下运动，对线屑进行清理；调节组件3与清理组件2连接，且能带动清理组件2在第一姿态和第二姿态间切换，且当清理组件2处于第一姿态时，清理组件2与蒸发器20的迎风面201接触并对蒸发器20的迎风面201进行线屑清理；当清理组件2位于第二姿态时， 清理组件2与蒸发器20分离。
通过设置长条状的清理组件2，可以通过驱动组件1带动清理组件2从蒸发器20的上端向下端移动，使清理组件2对蒸发器20的迎风面201进行接触清理，使迎风面201上的线屑被清理组件2刮下，该种机械式的线屑清理方式，能够对附着在蒸发器20上的线屑施加一定的作用力，从而容易带动线屑蒸发器20的表面脱离，实现对蒸发器20上线屑的彻底和完全清理，清理效果好且效率高。通过设置调节组件3，可以使清理组件2在从蒸发器20上端向下端移动的过程中，使清理组件2与迎风面201接触，对迎风面201上的线屑进行从上而下的扫落；当清理组件2从蒸发器20下端向上端回复移动的过程中，使清理组件2与蒸发器20分离，从而清理组件2不会将扫落在蒸发器20下端的线屑带回至蒸发器20的上端，保证线屑清理装置10对线屑的清理作用。
在一些实施例中，如图1所示，安装架与蒸发器20连接，安装架为框体结构，且安装架的一端与蒸发器20垂直连接。在一些实施例中，安装架具有平行设置地框架底板62和框架顶板61，以及连接框架顶板61和框架底板62的两个框架侧板63。框架顶板61、框架底板62和两个框架侧板63形成有具有两端开口的容纳空间，且一端开口朝向蒸发器20，清理组件2、调节组件3和导向组件4均设置在容纳空间内。
容纳空间内设置有清理架5，清理架5沿蒸发器20的长度方向设置，清理组件2设置在清理架5上，且清理架5与驱动组件1连接，带动清理组件2随清理架5一同沿蒸发器20的高度方向运动。
在本实施例种，驱动组件1包括驱动电机11和传动组件，传动组件为丝杠螺母组件。驱动电机11设置在框架顶板61的上方，且外部设置有配置为保护驱动电机11的保护盖。所述丝杠螺母组件包括丝杆12和螺母部，丝杠12垂直 设置在框架底板62与框架顶板61之间，且丝杠12上端与驱动电机11的输出轴连接。清理架5内设置有螺母部，螺母部与丝杠12配合连接。当驱动电机11驱动丝杠12转动时，螺母部带动清理架5沿丝杠12的长度方向上下运动。
在其他实施例中，传动组件还可以为齿轮齿条组件，或链轮链条组件等，能将驱动电机11的转动转化为清理架5的移动的传动组件均可。且该种形式的传动组件较为常见，本实施例不对其他形式的传动组件进行赘述。
在其他实施例中，驱动组件1还可以为活塞缸，活塞缸的固定座与固定架连接，活塞杆与清理架5或清理组件2连接，通过活塞杆的伸缩运动带动清理组件2的运动。
导向组件4配置为为清理架5的运动进行导向，使清理架5的上下运动平稳准确，保证清理组件2对蒸发器20的有效清理。导向组件4包括导向杆41，导向杆41垂直连接在框架底板62和框架顶板61之间，清理架5与导向杆41滑动连接。在本实施例中，导向杆41在清理架5的两端分别设置有一个，避免导向杆41的设置对清理组件2的动作造成干涉，导向组件4还包括两个导向套42，两个导向套42分别连接在清理架5的两端，且两个导向套42分别套设在两个导向杆41上，每个导向套42与导向杆41滑动连接。
图2为本实施例提供的清理组件2处于第一状态下的结构示意图，图3是图2中I处的局部放大图，图4是本实施例提供的清理组件2处于第二状态下的结构示意图，图5是图4是J处的局部放大图结合图1-5所示，在本实施例中，清理组件2通过转动轴23与清理架5的两端转动连接，转动轴23平行于蒸发器20的长度方向。当清理组件2处于第一姿态时，清理组件2与迎风面201垂直接触，从而可以对蒸发器20进行接触式清理；当清理组件2处于第二姿态时，清理组件2与迎风面201倾斜呈预设夹角并与蒸发器20分离。
在一些实施例中，调节组件3包括换向杆31、第一换向凸台32和第二换向凸台33，换向杆31与清理组件2远离蒸发器20的一侧连接。第一换凸台32设置在蒸发器20下端，具体可以设置在框架底板62上，且对应换向杆31的位置，当清理组件2位于蒸发器20下端时，换向杆31的下表面能与第一换向凸台32接触。第二换凸台33设置在蒸发器20上端，具体可以设置在框架顶板61上，且对应换向杆31的位置，当清理组件2位于蒸发器20上端时，换向杆31的上表面能与第二换向凸台33接触。
当驱动组件1带动清理组件2从蒸发器20的上端运动到下端时，换向杆31与第一换向凸台32接触。由于驱动组件1带动清理架5继续运动的同时，第一换向凸台32向换向杆31施加向上的作用力，使换向杆31绕转动轴23向上转动，并带动清理组件2绕转动轴23向下转动，与蒸发器20的迎风面201倾斜，即换向杆31与第一换向凸台32的接触使清理组件2从第一姿态转化到第二姿态。
当驱动组件1带动清理组件2从蒸发器20的下端运动到上端时，换向杆31与第二换向凸台33接触。驱动组件1带动清理架5继续向上运动的同时，第二换向凸台33向换向杆31施加向下的作用力，使换向杆31绕转动轴23向下转动，并带动清洁组件2绕转动轴23向上转动回复水平位置，与迎风面201垂直接触，即换向杆31与第二换向凸台33的接触使清理组件2从第二姿态回复到第一姿态。
在本实施例中，换向杆31设置有两个，且两个换向杆31设置在清理组件2的两端，有利于换向过程中，清理组件2的受力平衡，实现清理组件2的平稳可靠换向。在其他实施例中，调节组件3可以沿清理组件2的长度方向设置三组或更多组。
换向杆31与第一换向凸台32接触和与第二换向凸台33的接触所导致的换向杆31的角度变化，可以通过驱动组件1的驱动进行控制，如，当换向杆31转动到一定位置时，驱动组件1停止运行等。
本实施例中对换向杆31转动角度的控制也可以采用机械结构进行限位，在一些实施例中，清理组件2包括固定部21和清理部22，固定部21和清理部22均为长条状结构，固定部21的一侧与清理部22连接，另一侧与清理架5通过转动轴23转动连接。清理架5至少包括限位顶板51和分别设置在限位顶板51两端的两块安装侧板52，限位顶板51与迎风面201垂直设置，两块安装侧板52分别沿限位顶板51的边缘垂直向下延伸。固定部21设置在两块安装侧板52之间，且两端分别与两块安装侧板52通过转动轴23转动连接。
当清理组件2处于第一姿态时，限位顶板51与固定部21的上表面接触或仅具有微小的间隙，以限制清理组件2向上转动或使清理组件2向上转动的范围处于清理部22与迎风面201不脱离接触的范围。即，当清理组件2转动至第一姿态时，限位顶板51限制清理组件2的进一步转动。
在本实施例中，可选固定部21为矩形结构，有利于与清理架5的配合连接和相对清理架5的转动。且限位顶板51的宽度范围至少覆盖固定部21宽度的一半，有利于更好的限定清理组件2的向上转动。
在一些实施例中，本实施例提供的清理架5还可以包括限位底板53，限位底板53与限位顶板51平行设置，且两端分别与两个安装侧板52连接。当清理组件2处于第一姿态时，限位底板53与固定部21相距预设距离，当清理组件2处于第一姿态时，限位底板53与固定部21接触，以限制清理组件2的向下转动范围。
在一些实施例中，清理架5还包括连接限位顶板51和限位底板53的连接 侧板54，使清理架5整体为包围固定部21的框架式结构，对清理组件2进行保护。连接侧板54对应换向杆31的位置开设有穿接口541，换向杆31的一端伸出穿接口541。
在本实施例中，清理架5和固定部21均为矩形结构，结构简单，易于加工。在其他实施例中，清理架5的形状可以根据固定部21的形状具体设置，或根据需要限定的位置关系进行具体设计，即限位顶板51的设置只要能满足当清理组件2处于第一姿态时，阻碍清理组件2的向上转动即可。限位底板53的设置，只要满足当清理组件2处于第二姿态时，阻碍清理组件2的向下转动即可。
在一些实施例中，调节组件3还包括锁定组件，用于对清理组件2处于第一姿态时的状态进行相对锁定，使清理组件2在对蒸发器20进行清理的过程中，不会随意转动，影响对蒸发器20线屑的清理效果。
具体地，在本实施例中，锁定组件包括设置在固定部21两端的两个卡凸34和开设在安装侧板52上的第一卡槽35。当清理组件2处于第一姿态时，两个卡凸34分别与对应的第一卡槽35卡接连接，对清理组件2的转动起到一定的限制作用，当清理组件2不存在较大的外力作用时，可以保持清理组件2位于第一姿态以对蒸发器20进行清理。
在本实施例中，安装侧板52上还开设有第二卡槽36，当清理组件2处于第二姿态时，卡凸34与第二卡槽36卡接连接，当清理组件2不存在较大外力作用时，保持清理组件2位于第二姿态以使清理组件2被驱动组件1带动上下运动的过程中，保持与蒸发器20的分离状态。
在其他实施例中，卡凸34可以设置在安装侧板52上，第一卡槽35和第二卡槽36可以设置在固定部21的端面上。在其他实施例中，卡凸34可以仅在固定部21的一侧设置一个，第一卡槽35和第二卡槽36对应卡凸34设置。
图6为本发明实施例提供的清理架5和清理组件2的局部结构示意图，如图6所示，第一卡槽35朝向第二卡槽36的槽壁设置有导向斜面361，导向斜面361沿第二卡槽36向第一卡槽35的方向倾斜向上设置，有利于当清理组件2由第二姿态转动到第一姿态时，对卡凸34从第二卡槽36转动到第一卡槽35的运动进行导向，减小卡凸34的转动阻力。
在本实施例中，卡凸34可选为圆台结构，且与固定部21连接端的外径大于未与固定部21连接端的外径，有利于卡凸34伸入第一卡槽35或第二卡槽36中。在其他实施例中，可以设置圆台状的第一卡槽35，且第一卡槽35朝向固定部21的直径大于远离固定部21的外径，有利于对卡凸34伸入第一卡槽35进行导向。
在本实施例中，卡凸34和/或清理架5可选为具有一定弹性结构，使卡凸34与安装侧板52中的一个能够发生挤压变形，有利于卡凸34在第一卡槽35和第二卡槽36件运动，且不会阻碍清理组件2的转动。
在本实施例中，清理部22可以为毛刷，刮板等能用于清理蒸发器20表面线屑的装置，且可选为毛刷等软性材料，避免对蒸发器20表面造成损害。
在本实施例中，为使清理组件2清理的线屑不在蒸发器20的下端发生堆积，框架底板62朝向蒸发器20的边缘与蒸发器20的迎风面201相距预设距离，使框架底板62与蒸发器20之间形成有用于线屑等通过的线屑落槽。蒸发器20下方设置有冷凝槽，冷凝槽用于接收蒸发器20上形成的冷凝水，线屑通过线屑落槽落入冷凝槽中，并通过水流冲到排水泵处排出。
在本实施例中，调节组件3实现清理组件2相对蒸发器20的迎风面201角度位置上的改变，在其他是实施例中，还可以采用调节组件3使清理组件2相对蒸发器20沿宽度方向的距离发生改变，如，第一姿态可以为清理组件2与蒸 发器20的迎风面201垂直接触，第二姿态可以为清理组件2与蒸发器20的迎风面201相距预设距离，当第一姿态向第二姿态转换时，调节组件3带动清洁组件朝远离蒸发器20的方向运动，当第二姿态向第一姿态转换时，调节组件3带动清洁组件沿朝向蒸发器20的方向运动。在其他实施例中，还可以有其他能够实现清理组件2在与蒸发器20迎风面201接触的第一姿态及与蒸发器20分离的第二姿态间切换的调节组件3结构，本实施例不再赘述。
本文提供的线屑清理装置，通过将清理组件配置成能与蒸发器的迎风面接触的第一姿态和与迎风面分离的第二姿态，当清理组件处于第一姿态时，清理组件对蒸发器的迎风面进行接触清理，使蒸发器的迎风面上的线屑被清理组件刮下，该种机械式的线屑清理方式，能够对附着在蒸发器上的线屑施加一定的作用力，从而容易带动线屑蒸发器的表面脱离，实现对蒸发器上线屑的彻底和完全清理，清理效果好且效率高；当清理组件位于第二姿态时，清理组件与蒸发器分离，从而清理组件不会将扫落在蒸发器下端的线屑带回至蒸发器的上端，保证线屑清理装置对线屑的清理作用。
本文提供的干衣机，通过采用上述的线屑清理装置，能够对蒸发器上附着的线屑进行有效地清理，保证干衣机的烘干效率。
