Description

浊度传感器的安装结构及洗衣机 技术领域
本公开涉及水质检测技术领域，例如涉及一种浊度传感器的安装结构及洗衣机。
背景技术
随着技术的发展和用户需求的提升，越来越多的传感技术应用于洗衣机，其中设置为检测水质的浊度传感器受到越来越广泛的应用。通过检测洗涤水的浊度，可以判断衣物是否需要继续洗涤或者漂洗，实现了在保证洗涤效果的同时还能避免水电的浪费。浊度传感器一般是利用光学原理实现水质检测。
相关技术中浊度传感器多数是由光发射部发出沿直线传播的光，然后由位于光路上的光接收部接收，利用光接收部接收的光的强度等参数判断水质的浊度。浊度传感器上的光发射部和光接收部相对设置。当上述浊度传感器应用到洗衣机上时，由于洗涤水经内桶壁和外桶壁之间的区域后排出，所以浊度传感器安装在该区域中。另外，由于该区域为环状，受该区域形状结构的影响，光发射部和光接收部需要伸入到待检测水中进行检测。
发明内容
本公开提出一种浊度传感器的安装结构，能够解决光发射部和光接收部表面沉积的脏污不易清洗的问题。
本公开还提出一种洗衣机，包括上述浊度传感器的安装结构，能够解决洗衣机上浊度传感器的光发射部和光接收部表面不易清洗和容易沉积脏污的问题，该洗衣机节省水电。
本公开采用以下技术方案。
一种浊度传感器的安装结构，包括浊度传感器，所述浊度传感器包括光发射部和光接收部，所述光发射部和光接收部位于待检测区域的任一表面的同一侧，且所述光发射部和光接收部朝向待检测区域的一面均通过透明的封装块封装。
可选地，所述待检测区域为待检测水。
可选地，所述封装块朝向待检测水的一面为平面。

可选地，所述光发射部为红外发光管，所述光接收部为光传感器。
可选地，所述光发射部和光接收部位于同一封装块中。
一种洗衣机，具有上述的浊度传感器的安装结构，所述浊度传感器的安装结构镶嵌在所述洗衣机的外桶壁或桶底上。
可选地，当所述浊度传感器的安装结构镶嵌在所述洗衣机的外桶壁上时，所述封装块朝向待检测区域的一面与所述外桶壁的内表面位于同一竖直面内。
可选地，当所述浊度传感器的安装结构镶嵌在所述洗衣机的桶底上时，所述封装块朝向待检测区域的一面与所述桶底的内表面位于同一水平面内。
可选地，所述洗衣机包括设置为清洗外桶壁的内表面和桶底内表面的清洗结构，所述清洗结构能够清洗所述封装块朝向待检测区域的表面。
可选地，所述洗衣机为免清洗洗衣机，该免清洗洗衣机的内桶壁和外桶壁之间存在清洗颗粒。
本公开提出的浊度传感器的安装结构，利用透明的封装块将浊度传感器的光发射部和光吸收部朝向待检测区域的一面进行封装，光发射部和光接收部位于待检测区域的任一表面的同一侧，与相关技术中相对设置的浊度传感器相比，更容易清洗光发射部和光接收部的表面。将该安装结构设置在洗衣机的外桶壁上时，由于封装块的外表面竖直设置，光发射部和光接收部的表面不易沉积污渍，所以能够精确的测量洗涤水的浊度，能够保证洗衣效果，并且能够节水节电。

具体实施方式
在不冲突的情况下，以下实施例和实施例中的特征可以相互组合。下面结合附图并通过具体实施方式来说明本公开的技术方案。
相关技术中浊度传感器具有以下缺陷：1、光发射部和光接收部相对设置，两者之间为一凹陷结构，光发射部和光接收部表面的脏污不易清理，而沉积于表面的脏污将造成光接收部检测到的光强度产生偏差，无法准确判断衣物的洁净程度，造成浊度传感器在洗衣机上的使用受限；2、上述浊度传感器伸入到待检测水中，待检测水中的脏污容易沉积在浊度传感器光发射部和光接收部的表面上，导致该浊度传感器很容易产生浊度检测不准确的问题，导致浊度传感器的使用寿命缩短。
实施例1
参照图1和图2，本实施例提供一种浊度传感器的安装结构，该安装结构包括浊度传感器101，浊度传感器101包括光发射部111和光接收部112，光发射部111和光接收部112位于待检测区域的任一表面的同一侧，且光发射部111和光接收部112朝向待检测区域的一面均通过透明的封装块102封装。图1中封装块102可以为一块完整的封装块，也可以包括多个分离的小封装块。
该浊度传感器的安装结构的光发射部111和光接收部112位于待检测区域的任一表面的同一侧，相对于相关技术中的光发射部和光接收部分别设在待检测区域一表面的两侧，该浊度传感器101结构更容易清理，能够改善光发射部111和光接收部112表面脏污不易清理的情况。
可选地，所述待检测区域为待检测水。
可选地，在本实施例中，光发射部111和光接收部112可以位于同一封装块102中，使得浊度传感器101的安装结构更加紧凑，容易装配。可选地，封装块102朝向待检测水的一面为平面，由于平面结构容易清理，采用毛刷、刮片即能清洁脏污，减小了脏污给浊度检测带来的影响。
可选地，本实施例中的浊度传感器101采用的是光的反射原理，光发射部111向待检测水中发射光线，光接收部112接收待检测水中脏污粒子104反射的光线。由于光线经过了反射过程，因此本实施例中的封装块102朝向待检测水 的一面可以为平面，当光接收部112接收到的光线强度大时，说明待检测水中的脏污粒子104较多，反之，则说明待检测水比较干净。另外，为了防止其他结构的反射光线对浊度检测结果造成影响，浊度传感器的安装结构还可以包括黑色的光吸收部103。黑色的光吸收部103与浊度传感器101位于待检测水的不同侧，能够吸收未被脏污粒子104反射的光线，防止光线遇到其他结构后反射到光接收部113上而影响浊度检测的结果。
可选地，本实施例中的光发射部111为红外发光管，光接收部112为光传感器，红外发光管和光传感器均安装在印刷电路板113上，且红外发光管的发射端和光传感器的接收端位于同一平面上。采用红外线浊度传感器检测水的浊度，结构简单，成本低。
实施例2
参考图3，本实施例提供一种洗衣机，该洗衣机具有上述浊度传感器的安装结构，浊度传感器的安装结构镶嵌在洗衣机的外桶壁201或者桶底上。
如图3所示，可选地，当浊度传感器的安装结构安装在外桶壁201上时，封装块102朝向待检测区域(例如待检测水)的一面与外桶壁201的内表面位于同一竖直面内。在洗衣机正常工作时，封装块102表面是竖直面，不易沉积脏污，提高了浊度传感器101的使用时间。
可选地，上述浊度传感器的安装结构中的黑色的光吸收部103为黑色内桶壁。采用黑色内桶壁能够防止内桶壁反射的光线射入光接收部112，避免了由于内桶壁反射光线而造成检测到的脏污粒子104增加导致洗衣机继续对衣物进行洗涤，实现了节水节电。光吸收部103还可以设计为其他挡板结构，能够防止反射光线对检测结果造成影响即可。
可选地，当浊度传感器的安装结构安装在桶底上时，封装块102朝向待检测区域(例如待检测水)的一面与桶底的内表面位于同一水平面内。当有脏污沉积在封装块102朝向待检测区域的表面时，利用简单的清洗工具即能完成清理，如采用毛刷或刮片。由于脏污易清理，因此浊度传感器101安装在桶底，不易对浊度检测造成影响。相应的，在与桶底相对的位置安装黑色的光吸收部103，能够防止与桶底相对的位置反射的光线射入光接收部112。
图4是本实施例提供的洗衣机的清洗结构的示意图，如图4所示，可选地，洗衣机还包括设置为清洗外桶壁201的内表面和桶底内表面的清洗结构203，清洗结构203能够清洗所述封装块102朝向待检测区域(例如待检测水)的表面。 该清洗结构203在清洗外桶壁201和桶底时，能够一并将安装在外桶壁201或桶底上的封装块102朝向待检测水的表面清洗干净，防止封装块102表面沉积脏污后对光发射部111和光接收部112造成影响。清洗结构203可以是毛刷或刮片(图4中的清洗结构203为毛刷状)；可以由电机控制，也可以通过水流的流动带动毛刷或刮片的移动。
可选地，本实施例中的洗衣机还可以为免清洗洗衣机，该免清洗洗衣机的内桶壁和外桶壁201之间存在清洗颗粒202。下面以浊度传感器的安装结构位于外桶壁201上为例，说明免清洗洗衣机对封装块102朝向待检测水的一侧表面进行清洁的过程。
如图3所示，免清洗洗衣机在洗涤时，水流带动软质的清洗颗粒202在内外桶之间不停地运动，运动的清洗颗粒202不断地对桶壁形成撞击、挤压和摩擦，同时，在清洗颗粒202运动过程中形成的水流使得洗涤水中的污渍不能在外桶壁201上附着和沉积，从而可以保持外桶壁201的持久清洁。当封装块102与洗涤水接触的一面与外桶壁201内表面平齐时，在清洗颗粒202运动过程中，可以同时对封装块102的表面进行清洗。因此，安装在免清洗洗衣机的外桶壁201上的封装块102能够在每次洗衣时均保持洁净，不会由于脏污的沉积而对洗涤水的浊度检测造成影响。需要说明的是，清洗颗粒202与脏污粒子104的粒径大小相差很大，浊度传感器101的控制器能够区分清洗颗粒202与脏污粒子104对光反射后产生的信号，并且能够进行不同信号的分离，因此，清洗颗粒202不会对洗涤水浊度的检测结果造成影响。
当封装块102与桶底的内表面平齐时，清洗颗粒202同时对桶底和封装块102进行清洗，保证了封装块102朝向待检测水的一侧表面的清洁，避免脏污对洗涤水的浊度检测造成影响。
封装块102可以选用耐磨材料，避免在清洗过程中受到摩擦而导致造成损坏。
工业实用性
本公开提供的浊度传感器的安装结构，利用透明的封装块将浊度传感器的光发射部和光吸收部朝向待检测区域的一面进行封装，光发射部和光接收部位于待检测区域的任一表面的同一侧，与相关技术中相对设置的浊度传感器相比，更容易清洗光发射部和光接收部的表面。
