Description

一种采用远红外加热的干衣机及其干衣控制方法 技术领域
本发明涉及干衣机领域，具体涉及一种采用远红外加热的干衣机及其干衣控制方法。
背景技术
现有技术中，有的干衣机或洗干一体机采用远红外加热技术对衣物进行烘干，具体的，在干衣机或洗干一体机的烘干滚筒上或烘干滚筒外侧设置远红外加热器，远红外加热器可以发出远红外线，远红外线具有被水分吸收而不被空气吸收的能量特性，所以远红外线照射到烘干滚筒内部被加热物体内的水分吸收，直接转变成热能将被加热物体内的水分转变成水蒸气排出。
但是，现有的干衣机或洗干一体机采用远红外加热技术，一般是通过设置在PCB(Printed Circuit Board)印刷电路板上的一个继电器控制一组远红外加热器的通断，在每个远红外加热器附近均安装一个温控器以防止远红外加热器温度过高，并且在烘干滚筒内设置一个温度传感器以控制桶内温度不超标。所以采用现有的远红外加热控制方式，每片远红外加热器都需要配置一个继电器和温控器进行控制，整个干衣机或洗干一体机内需要设置多组继电器和温控器，线路繁琐而且浪费成本。
远红外加热器采用TCM材料，TCM(Tin Ceramic Membrane)是功能陶瓷复合电热新材料，其特点是电能转化为热能再转化为远红外线，可制成低、中温高效远红外元件，产生丰富的长波远红外线，是电热领域首创、节能、最前沿的高科技新产品，热效率达92％，比常规电热元件节电20％-30％，作为清洁能源 完全符合环保要求。当将远红外加热器使用在干衣机或洗干一体机上进行衣物烘干时，由于远红外加热器的功率密度比较低，需要比较大片的加热面积，现有的远红外加热器一般单片功率在200-400W之间，以普通5kg干衣机为例，至少需要3-6片远红外加热器。如果采用现有的加热控制方式，则每片远红外加热器都需要配置一个继电器和温控器，也就是3-6组继电器和温控器，线路繁琐而且浪费成本。

具体实施方式
为使本发明解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将结合附图对本发明实施例的技术方案作进一步的详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
装置实施例
本申请提供的远红外加热器既可以应用在洗干一体机又可以应用在干衣机上，以下以干衣机为例进行介绍。干衣机包括箱体以及远红外干衣控制系统，所述远红外干衣控制系统包括干衣滚筒，所述干衣滚筒可转动的设置于所述箱体内部。图1是本发明装置实施例提供的远红外干衣控制系统的结构示意图。如图1所示，所述远红外干衣控制系统还包括至少一个远红外加热器1、用于检测干衣滚筒排气湿度的湿度传感器6、继电器3及输出端与所述继电器3相连的 控制器2，所述控制器2与电源4相连，所有远红外加热器1通过一个所述继电器3与电源4连接，其中一个所述远红外加热器1内部安装有一个第一温度传感器5，所述第一温度传感器5和所述湿度传感器6与所述控制器2的输入端相连，所述控制器2根据接收的温度信号或湿度信号控制所述继电器3的开合。
工作时，第一温度传感器5检测远红外加热器1内的远红外加热器内的温度并以信号的形式传递给控制器2，同时湿度传感器6检测干衣滚筒所排出气体的湿度并以信号的形式传递给控制器2。
控制器2将接收到的远红外加热器内的温度与预设上限温度Tmax1和预设下限温度Tmin1进行比较，当远红外加热器内的温度大于预设上限温度Tmax1时，控制继电器3断开；当远红外加热器内的温度小于预设下限温度Tmin1时，控制继电器3闭合；同时控制器2将接收到的湿度值与预设湿度值进行比较，当湿度值小于预设湿度值时，控制继电器3断开，并且终止烘干过程。
由于远红外加热器1自身具有温度限制特性(根据TCM膜系不同温度不同，一般200-400度)和高度一致性，本控制系统不再采用机械温控器，而只在一片远红外加热器1上安装一个第一温度传感器5用于检测和控制温度。具体的，所述第一温度传感器5安装于所述远红外加热器1内侧。远红外加热器1的电流具有逐步增大的特性，不再采用多个继电器3分别控制，而只用一只继电器3控制所有远红外加热器1。这样，本系统只采用一个第一温度传感器5和一个继电器3就控制了所有远红外加热器1，简化了电路，也节约了成本。
于本实施例中，所述远红外加热器1既可以安装在所述干衣滚筒上又可以安装在所述干衣滚筒和箱体之间。当所述远红外加热器1安装在所述干衣滚筒上时，所述干衣滚筒上设置有安装孔，所述远红外加热器1安装在所述安装孔中以对干衣滚筒内部进行加热。
于本实施例中，作为另一种优选，当所述远红外加热器1安装在所述干衣滚筒和箱体之间时，所述干衣滚筒上设有至少一组孔阵列，每组所述孔阵列均由多个孔组成，所述远红外加热器1设置在孔阵列的外侧，通过所述孔阵列可对所述干衣滚筒的内部进行加热。
由于现有技术中的衣物烘干系统中所使用的远红外加热器正常工作温度在600℃，异常情况下会达到1000℃，所以其对温度的控制就特别重要，除了上述提及的对远红外加热器进行温度检测和保护之外，其干衣滚筒内还设置有温度传感器，这个温度传感器用来检测干衣滚筒内温度，防止干衣滚筒内温度过高导致衣物损坏，这就要求整机配备较高功率的风机，以尽可能的使桶内温度均匀，风速稍低，风道稍有堵塞，就可能出现安全问题。
在本控制系统中，由于采用远红外加热器1对衣物进行加热，远红外加热器1本身温度被锁定，比如200膜系温度最高不超过200℃，超过该温度则自动断电。再加上其对衣物的加热不是通过空气媒介，而是通过发出的远红外线辐射直接加热衣服的水分。这两方面首先保证了使用的安全性，所以传统衣物烘干系统中干衣滚筒内设置的温度传感器就不再那么重要了，干衣滚筒内温度检测的准确性也不再依赖风速。然而，对于需要烘干的衣物如果采用化纤、羊毛等对温度要求比较高的布料做成的，则对干衣滚筒内的温度要求同样比较高。
因此，于本实施例中，作为优选方案，所述干衣机还设置有至少一个第二温度传感器7，所述第二温度传感器7与所述控制器2的输入端相连，用于检测干衣滚筒内的温度并传递给控制器2，控制器2将接收到的干衣滚筒内的温度与预设上限温度Tmax2和预设下限温度Tmin2进行比较，当干衣滚筒内的温度大于预设上限温度Tmax2时，控制继电器3断开；当干衣滚筒内的温度小于预设下限温度Tmin2时，控制继电器3闭合。
于本实施例中，作为优选方案，所述第二温度传感器7设置在所述干衣机出风口处。
于本实施例中，所述第二温度传感器7的数量至少为一个。当第二温度传感器7的数量为多个时，所有第二温度传感器7将检测到的干衣滚筒内的温度传递给控制器2后，控制器2将接收到的所有干衣滚筒内的温度取平均值，之后使用该平均值与预设上限温度Tmax2和预设下限温度Tmin2进行比较。
于本实施例中，作为优选方案，所述干衣机的进风口处设置有风机8，所述风机8的功率为10瓦至20瓦，所述风机8与所述控制器2相连，由控制器2控制风机8的转动。由于本控制系统避免了对风速的依赖，所以就避免了大功率风机的使用，只需要一个较小的风机进行辅助排湿就可以了，所以这种干衣机的噪音就会很低。
于本实施例中，由于本控制系统中采用小功率的风机，湿热气体会向干衣机顶部的出风口聚集，因此，作为优选方案，所述湿度传感器6置于干衣机的出风口处，以便更准确的测量湿度。
于本实施例中，作为优选方案，所述控制器2做成PCB集成电路板。
方法实施例
本申请还提供了一种采用远红外加热的干衣机控制方法，该干衣控制方法应用于其内设置有第一温度传感器5和湿度传感器6，而没有设置第二温度传感器7的采用远红外加热的干衣机。图2是本发明方法实施例提供的干衣控制方法流程图。如图2所示，控制方法包括步骤：
S11、烘干过程开始后，第一温度传感器5检测远红外加热器1内的远红外加热器内的温度并以信号的形式传递给控制器2，同时湿度传感器6检测干衣滚筒内气体的湿度并以信号的形式传递给控制器2。
S12、控制器2将接收到的湿度值与预设湿度值进行比较，当湿度值小于等于预设湿度值时，则表明干衣滚筒内的衣物已经被烘干，执行步骤S13；当湿度值大于预设湿度值时，执行步骤S14。
S13、控制器2判断继电器3是否处于断开状态，若没有处于断开状态，则控制继电器3处于断开状态，并且终止整个烘干过程。
S14、控制器3将接收到的远红外加热器内的温度与预设上限温度Tmax1和预设下限温度Tmin1进行比较，当远红外加热器内的温度大于预设上限温度Tmax1时，执行步骤S13；当远红外加热器内的温度小于预设下限温度Tmin1时，执行步骤S15；当远红外加热器内的温度小于等于预设上限温度Tmax1且大于等于预设下限温度Tmin1时，则控制器2不做出反应。
S15、控制器2判断继电器3是否处于闭合状态，若继电器3没有闭合，则控制器2控制继电器3闭合，远红外加热器1重新发射红外线。
于本实施例中，所述预设上限温度Tmax1的取值范围优选为190℃至210℃，但并不局限于此，可以根据具体情况而定。所述预设下限温度Tmin1的取值范围优选为140℃至160℃，但并不局限于此，可以根据具体情况而定。
本申请还提供了另一种采用远红外加热的干衣机控制方法，该控制方法应用于其内设置有第一温度传感器5和湿度传感器6，同时滚筒内设置有第二温度传感器7的采用远红外加热的干衣机。图3是本发明方法实施例提供的干衣控制方法一种优选方式流程图。如图3所示，控制方法包括步骤：
S21、烘干过程开始后，第一温度传感器5检测远红外加热器1内的远红外加热器内的温度并以信号的形式传递给控制器2，湿度传感器5检测干衣滚筒内气体的湿度并以信号的形式传递给控制器2，同时第二温度传感器7检测干衣滚筒内的温度并以信号的形式传递给控制器2。
S22、控制器2将接收到的湿度值与预设湿度值进行比较，当湿度值大于预设湿度值时，执行步骤S24；当湿度值小于等于预设湿度值时，则表明干衣滚筒内的衣物已经被烘干，执行步骤S23。
S23、控制器2判断继电器3是否处于断开状态，若没有处于断开状态，则控制继电器3处于断开状态，并且终止整个烘干过程。
S24、控制器2将接收到的远红外加热器内的温度与预设上限温度Tmax1和预设下限温度Tmin1进行比较，并将接收到的干衣滚筒内的温度与预设上限温度Tmax2和预设下限温度Tmin2进行比较，当远红外加热器内的温度大于预设上限温度Tmax1，干衣滚筒内的温度大于预设上限温度Tmax2至少满足其中之一时，则表明干衣滚筒内的温度和/或远红外加热器1内的温度过高，为了防止烧坏衣物和/或远红外加热器1，执行步骤S23；当远红外加热器内的温度小于预设下限温度Tmin1，干衣滚筒内的温度小于预设下限温度Tmin2至少满足其中之一时，则表明干衣滚筒内的温度和/或远红外加热器1内的温度过低，执行步骤S25；否则，控制器2不做出反应。
S25、控制器2判断继电器3是否处于闭合状态，若没有处于闭合状态，则控制继电器3闭合，远红外加热器1重新发射红外线给干衣滚筒内的衣物继续加热。
注意，上述仅为本发明的较佳实施例及所运用技术原理。本领域技术人员会理解，本发明不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整和替代而不会脱离本发明的保护范围。因此，虽然通过以上实施例对本发明进行了较为详细的说明，但是本发明不仅仅限于以上实施例，在不脱离本发明构思的情况下，还可以包括更多其他等效实施例，而本发明的范围由所附的权利要求范围决定。
