Description

一种除湿机用水满报警装置
本申请要求于2016年03月28日提交中国专利局、申请号为201610181914.1、发明名称为“一种除湿机用水满报警装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及除湿设备技术领域，尤其涉及一种除湿机用水满报警装置。
背景技术
除湿机中用于收集水的装置为集水箱，当集水箱内的水积攒至一定量时，需要提醒用户进行清除或者直接切断除湿机电源以免水由集水箱溢出而破坏室内环境。
示例的，图1为现有技术的一种除湿机，除湿机中设有水满报警装置，如图1所示，水满报警装置包括固定于支撑架01上的微动开关02、穿设于除湿机壳体03上的触动杆04以及铰接于集水箱05内的浮标06，其中，如图2a所示，微动开关02上设有按钮07，按钮上压设有弹片08，弹片08的一端固定于微动开关02上，另一端自由；触动杆04的一端与弹片08抵靠，另一端与浮标06的一端抵靠。当集水箱05内的水量较少时，浮标06在自身重力作用下使触动杆04顶住弹片08以顶住微动开关02，此时，除湿机处于通电状态；当集水箱05内水位到达一定程度时，浮标06随水位的升高而上浮，进而使浮标06对触动杆04的作用力减小，触动杆04与微动开关02发生分离，此时，除湿机处于断电状态。由此实现了水满报警操作。此结构简单，容易实现。
但是，由于水满报警装置由微动开关02、触动杆04和浮标06三部分组成，且触动杆04与微动开关02和浮标06之间均通过抵靠的方式进行连接，因此结构松散，尺寸链较长，在长时间使用之后，触动杆04与微动开关02上的弹片08之间，以及触动杆04与浮标06之间均出现了摩擦磨损，两部分磨损叠加后将会大幅度降低水满 报警装置的传动精度，因此系统响应的可靠性及稳定性较低。
发明内容
本发明提供一种除湿机用水满报警装置，能够提高系统响应的可靠性及稳定性。
为达到上述目的，本发明提供了一种除湿机用水满报警装置，包括报警开关，所述报警开关包括开关按钮，所述开关按钮上盖设有弹片，所述弹片的一端固定，另一端自由，还包括可旋转的支架，所述支架的第一端连接有浮子，第二端与所述弹片抵靠，当所述浮子上浮时，所述支架抵靠所述弹片的一端可绕自身的旋转轴线摆动并驱动所述弹片触发所述开关按钮。
本发明提供的一种除湿机用水满报警装置，当水箱内水位到达一定程度时，浮子随水位的升高而上浮，推动支架绕自身旋转轴线摆动，支架抵靠弹片的一端在摆动的过程中可驱动弹片触发开关按钮，开关按钮被触发后可实现报警操作。相比于现有技术中通过微动开关上弹片与触动杆、触动杆与浮标之间的相互传动实现报警触发，本发明实施例仅通过连接浮子的支架与弹片进行传动实现报警触发，结构简单紧凑，尺寸链较短，系统响应的可靠性及稳定性较高。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，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，本领域普通技术人员在没有做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。
在本发明的描述中，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发明和简化描述，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发明的限制。
除湿机内设有集水箱，集水箱可由除湿机的壳体内取出，支架安装于集水箱内，报警开关以及弹片设置于除湿机的壳体外，支架的第一端位于集水箱内并与浮子连接，第二端伸出壳体外与弹片抵靠。
参照图5，图5为本发明实施例除湿机用水满报警装置的一个具体实施例，本实施例的除湿机用水满报警装置包括报警开关1，所述报警开关1包括开关按钮2，所述开关按钮2上盖设有弹片3， 所述弹片3的一端固定，另一端自由，还包括可旋转的支架4，所述支架4的第一端连接有浮子5，第二端与所述弹片3抵靠，当所述浮子5上浮时，所述支架4抵靠所述弹片3的一端可绕自身的旋转轴线摆动并驱动所述弹片3触发所述开关按钮2。
本发明提供的一种除湿机用水满报警装置，当水箱内水位到达一定程度时，浮子5随水位的升高而上浮，推动支架4绕自身旋转轴线摆动，支架4抵靠弹片3的一端在摆动的过程中可驱动弹片3触发开关按钮2，开关按钮2被触发后可实现报警操作。相比于现有技术中通过微动开关上弹片3与触动杆、触动杆与浮标之间的相互传动实现报警触发，本发明实施例仅通过连接浮子5的支架4与弹片3进行传动实现报警触发，结构简单紧凑，尺寸链较短，系统响应的可靠性及稳定性较高。
在上述实施例中，当开关按钮2被触发时，报警开关1执行的报警操作可以为发出报警声音提醒用户水已满，也可以在显示屏上显示“水满”字样提醒用户水已满，还可以直接切断除湿机的开关电源以停止除湿运行，在此不做具体限定，只要能够将水满信息传递至用户即可。
其中，开关按钮2、弹片3、支架4以及浮子5之间的动作过程为：在初始状态下，浮子5在自身重力作用下使支架4抵靠弹片3的一端顶住弹片3以顶住开关按钮2，而当集水箱内的水位到达一定程度并逐渐上涨时，浮子5随着水位的升高而上浮，使支架4抵靠弹片3的一端对弹片3的作用力减小，弹片3与开关按钮2发生分离以触发此报警开关1。
另外，弹片3的固定端可以为如图5所示的固定于报警开关1上，也可以固定于除湿机壳体外的支撑架上，还可以固定于除湿机的壳体上，在此不做具体限定，只要弹片3的固定端相对于报警开关1、水箱以及支架4的旋转轴线位置固定即可。
需要说明的是，为了方便描述，定义过支架4旋转轴线的竖直平面为第一平面。初始状态时，支架4的第一端与第二端可以位于 第一平面的两侧，也可以位于第一平面的同一侧，在此不做具体限定，只要浮子5上浮时，支架4抵靠弹片3的一端可绕自身旋转轴线摆动即可。当支架4的第一端与第二端位于第一平面的两侧时，浮子5上浮，支架4的第一端向上摆动，支架4的第二端向下摆动；当支架4的第一端与第二端位于第一平面的同侧时，浮子5上浮，支架4的第一端和第二端均绕自身旋转轴线向上摆动。
在如图2a所示的现有技术中，浮标06与触动杆04抵靠的一端设有四分之一圆弧面，圆弧面的顶端形成有尖角K，正常状态下，触动杆04的端部与圆弧面相抵靠，此时，若浮标06上浮，浮标06通过此圆弧面可平缓推动触动杆04移动。但是，在运输除湿机的过程中，基于降低装置重心等原因，通常需要将除湿机倾倒放置，而此时，浮标06在自身重力的作用下可逆时针旋转较大角度，使触动杆04的端部脱离圆弧面，而使圆弧面顶端的尖角K为如图2b所示抵靠于触动杆04的侧壁上，而当除湿机被重新扶正之后，如图2c所示，圆弧面顶端K尖角仍然卡在触动杆04的侧壁上难以恢复至正常状态，此时开机运行即显示报警。为了避免上述问题，优选的，支架4抵靠弹片的一端可以制作为如图5所示结构，即，支架4抵靠弹片3的一端设有凸缘41，所述凸缘41的轮廓曲线光滑且连续，当支架4绕自身旋转轴线摆动时，所述弹片3始终与所述凸缘41抵靠。由此，如图6a所示，在倾倒放置除湿机时，支架4逆时针旋转较大角度，弹片3仍与凸缘41抵靠，由于凸缘41所在曲线为连续，因此在重新扶正除湿机时，如图6b所示，支架4可在浮子5的重力作用下重新恢复至正常状态，从而有效避免了卡死现象，使除湿机开机后即可正常运行。
在图2a所示的现有技术中，由于微动开关02固定于支撑架01上，而浮标06的旋转轴线固定于集水箱05内，若支撑架01与集水箱05之间的相对位置(如支撑架01与集水箱05之间的相对高度)出现偏差，将会严重影响报警装置的触动准确性。示例的，如图3所示，在浮标06上浮之前，由于支撑架01与集水箱05之间的相对 高度出现偏差，使浮标06的位置由位置A偏离至位置B，此时触动杆04抵靠弹片08的一端伸出壳体03的长度产生了偏差，弹片08与按钮07之间的相对位置出现了偏差，导致水满后仍不能使弹片08与按钮07分离，从而出现报警错误，影响了报警装置的触动准确性，而且当浮标06的位置由位置A偏离至位置B时，触动杆04抵靠弹片08的一端伸出壳体03的长度偏大，弹片08与按钮07之间的间隙为负值，触动杆04对浮标06的反作用力偏大，使浮标06在原有的较小初始浮力矩的作用下难以上浮而出现卡死现象。为了避免上述问题，优选的，如图5所示，弹片3竖直设置，当支架4出现高度偏差时，弹片3不会出现摆动，由此保证了报警装置的触动准确性，提高了报警装置的抗偏差干扰的能力。示例的，如图7所示，在浮标上浮之前，由于支撑架与集水箱之间的相对高度出现偏差，使支架4的位置由位置A′偏离至位置B′，此时弹片3上与支架4的触点位置由a点竖直移动到了b点，而弹片3的位置保持不变，弹片3与开关按钮2之间的相对位置保持不变，由此避免了报警错误，从而保证了报警装置的触动准确性，而且当支架4的位置由位置A′偏离至位置B′时，弹片3与支架4之间未产生相互挤压，相互作用力保持不变，不会影响浮子5的上浮。
需要说明的是，水满报警装置的尺寸偏差主要考虑报警开关1与支架4旋转轴线之间的相对位置偏差，报警开关1与支架4旋转轴线之间的相对位置偏差包括水平方向上的偏差和竖直方向上的偏差，由于在除湿机内通常设置有保证水平方向上安装精度的限位结构，因此报警开关1与支架4旋转轴线之间的相对位置偏差主要考虑竖直方向上的偏差。
其中，支架4与浮子5之间的连接结构可以为如图8所示结构，即，支架4连接浮子5的一端嵌入浮子5内部实现固定，还可以为如图5所示结构，即，支架4连接浮子5的一端固定有浮子安装盒6，浮子安装盒6上设有安装口7，浮子5可穿过安装口7连接于浮子安装盒6内。相比于上述第一种方案，采用上述第二种方案将浮 子5安装于浮子安装盒6内，可有效固定浮子5与支架4的相对位置，防止浮子5脱离支架4。
为了防止浮子5借助浮力由安装口7脱出，优选的，如图5所示，安装口7开设于浮子安装盒6的下端，浮子5安装于浮子安装盒6内后，浮子5的浮力方向与浮子5由安装口7脱出的移动方向相反，由此，当浮子5上浮时，浮子5的浮力可将浮子5紧紧的压设于浮子安装盒6内，避免浮子5脱离浮子安装盒6。而相反，若将安装口7开设于浮子安装盒6的上端，则浮子5的浮力方向与浮子5由安装口7脱出的移动方向相同，有利于浮子5借助浮力由安装口7脱出。
作为浮子5与浮子安装盒6之间连接结构的一种实施例，浮子安装盒6内设有内螺纹，浮子5的外壁设有可与此内螺纹配合的外螺纹，浮子5通过外螺纹配合连接于浮子安装盒6内，此连接结构具有稳定性好、精度高的优点。
作为浮子5与浮子安装盒6之间连接结构的另一种实施例，浮子安装盒6内设有卡接结构，浮子5可通过卡接结构卡接于浮子安装盒6内，由此通过卡接的方式将浮子5安装于浮子安装盒6内，相比于螺纹连接的方式，卡接操作耗时较短，效率较高。
其中，卡接结构可以为卡扣、凸起等等，在此不做具体限定。为了降低卡接结构的制作难度，如图9所示，卡接结构可以为设置于浮子安装盒6内壁的筋条8，筋条8与浮子5的侧壁过盈配合。此卡接结构简单，容易实现。
为了减小将浮子5卡接于浮子安装盒6内时的所用的力，以降低卡接难度，优选的，如图9所示，筋条8的延伸方向与浮子5在浮子安装盒6内安装时的移动方向平行，由此阻止浮子5进入浮子安装盒6内的面为筋条8的截面，筋条8的截面面积较小，仅需较小的作用力即可将浮子5压入浮子安装盒6内，卡接难度较低。
为了提高浮子5与浮子安装盒6之间连接的可靠性，浮子安装盒6可以制作为如图9所示结构，即，浮子安装盒6的内壁设有卡 扣9，浮子5的外壁设有卡槽，当浮子5安装于浮子安装盒6内时，卡扣9可卡接于卡槽内，由此通过卡扣9与卡槽之间相互卡接固定了浮子5与浮子安装盒6的相对位置，提高了浮子5与浮子安装盒6之间的连接可靠性。
为了进一步地提高浮子5与浮子安装盒6之间连接的可靠性，浮子安装盒6可以制作为如图9所示结构，即，卡扣9为多个，且多个卡扣9围绕浮子安装盒6的内壁一周均匀设置，卡槽为多个，且多个卡槽围绕浮子5的外壁一周均匀设置，多个卡扣9和多个卡槽一一对应卡接，由此通过多个卡扣9与多个卡槽对应卡接进一步地提高了浮子5与浮子安装盒6之间连接的可靠性。
其中，卡扣9的结构可以为如图10所示，即，卡扣9包括固定端91和卡接端92，卡扣9的卡接端92位于固定端91靠近安装口7的一侧，由此当浮子5向靠近安装口7的方向移动并准备脱离浮子安装盒6时，卡扣9受力而向外张开，不能有效阻止浮子5脱离浮子安装盒6。为了避免上述问题，优选的，如图11所示，卡扣9的卡接端92位于固定端91远离安装口7的一侧，由此当浮子5向靠近安装口7的方向移动并准备脱离浮子安装盒6时，卡扣9受力矩而将浮子5抱死以阻止浮子5由浮子安装盒6内脱出，从而更进一步的提高了浮子5与浮子安装盒6的连接可靠性。
另外，卡扣9的具体结构可以为如图9所示包括竖直凸起和水平凸起，竖直凸起的一段固定，另一端自由，水平凸起固定于竖直凸起的自由端，其中水平凸起卡接于卡槽内，也可以为一端固定于浮子安装盒6内壁、另一端倾斜设置的弹片，当然还可以为其他结构，在此不做具体限定。
如图2a所示的现有技术中，浮力力臂(即如图2a所示的L)通常在20mm以下，在此力臂的作用下，驱动浮标06旋转的浮力力矩较小，若浮标06与触动杆04之间出现卡死，在此较小的浮力力矩的作用下将难以驱动浮标06上浮，从而使水满报警装置失效。为了避免上述问题，优选的，如图5所示，浮力力臂N(即浮子5与 支架4的旋转轴之间的水平距离)大于20mm，以增大驱动支架4旋转的浮力力矩，避免出现卡死的情况。
为了便于浮力确定，应将浮力施加于浮子5上，尽可能地避免将浮力施加于支架4上，因此，优选的，支架4的旋转轴固定，支架4连接浮子5的一端向下倾斜，当液位升高时，水首先与浮子5接触产生浮力，而不是与支架4接触，由此仅将浮力施加于浮子5上，从而有利于浮力的确定。
为了提高除湿机用水满报警装置的报警响应准确性，通常要求当浮子5处于低水位时，报警开关1对水位的上升不敏感，而当浮子5处于高水位时，报警开关1对水位的上升敏感，也即是，要求浮子5在低水位时的动作较小，在高水位时动作较大，最终反应在开关按钮2的释放量上即为：在低水位时，开关按钮2的释放量较小，在高水位时，开关按钮2的释放量较大，比如在低水位时，集水箱水位每升高1cm，开关按钮2的释放量为0.05mm，在高水位时，集水箱内水位每升高1cm，开关按钮2的释放量为0.2mm，由此即可提高除湿机用水满报警装置的报警响应准确性，又可降低除湿机用水满报警装置的机械磨损。但是，与上述要求相反，现有技术中，浮力驱动浮子5上浮均存在一个问题，即，低水位时转动快，而高水位时转动慢。示例的，如图12所示，浮子5由位置C先后上浮至位置D、位置E和位置F，其中，浮子5由位置C上浮至位置D的上浮高度为1cm，支架4的旋转角度为16°，由位置E上浮至位置F的上浮高度也为1cm，而支架4的旋转角度却减小到了6.5°。由此，为了尽可能地减小浮子5在高水位时转角变化量与低水位时转角变化量之间的差异，应增大浮子5处于初始位置时，支架4连接浮子5的一端与竖直方向的夹角，现有技术中支架4连接浮子5的一端与竖直方向的夹角通常在11.8度以下，为了增大支架4连接浮子5的一端与竖直方向的夹角，本发明应确定支架4连接浮子5的一端与竖直方向的夹角大于11.8°，也即是，支架4连接浮子5的一端向下倾斜的角度小于78.2°。示例的，如图13所示，曲线c为 现有技术中当支架4连接浮子5的一端与竖直方向的初始夹角为11.8°时，水位高度H与支架4旋转角度θ之间的关系曲线，曲线d为本发明当支架4连接浮子5的一端与竖直方向的初始夹角为22.4°时，水位高度H与支架4旋转角度θ之间的关系曲线。由图13可知，相比于现有技术，本发明实施例中水位高度与支架4旋转角度之间的变化关系更趋近于线性均匀变化，从而改善了浮子5的转动特性。
进一步的，为了使开关按钮2在低水位时，释放量较小，在高水位时，释放量较大，以提高除湿机用水满报警装置的报警响应准确性，优选的，随着支架4旋转角度的逐渐增大，凸缘41与弹片3之间的触点至支架4旋转轴线的水平距离的变化率逐渐增大，由此在低水位时，支架4抵靠弹片3的一端驱动弹片3绕固定端摆动的幅度较小，在高水位时，支架4抵靠弹片3的一端驱动弹片3绕固定端摆动的幅度较大，作用于开关按钮2上，即为：在低水位时，开关按钮2的释放量较小，在高水位时，开关按钮2的释放量较大，从而提高了除湿机用水满报警装置的报警响应准确性。示例的，假设凸缘41与弹片3之间的触点至支架4旋转轴线的水平距离为第一距离，如图14所示为第一距离的变化量L′与支架4旋转角度θ之间的关系，由图14可知，随着旋转角度θ的逐渐增大，第一距离的变化量L′逐渐增大，第一距离的变化率也逐渐增大。
更进一步的，为了使开关按钮2在低水位时，释放量较小，在高水位时，释放量较大，以提高除湿机用水满报警装置的报警响应准确性，优选的，当浮子5上浮时，凸缘41与弹片3之间的触点至弹片3的固定端的距离逐渐减小，由此根据相似三角形对应边成比例的原则，凸缘41与弹片3之间的触点越往弹片3的固定端靠近，触点水平移动单位距离对开关按钮2处的释放量的影响就越大。示例的，如图15所示，凸缘41与弹片3之间的触点位置由e点移动至f点，与弹片3固定端之间的距离减小，当凸缘41与弹片3之间的触点位置在e点水平方向移动1cm，则开关按钮2处的释放量为 0.1mm，当凸缘41与弹片3之间的触点位置在f点水平方向移动1cm，开关按钮2处的释放量为0.2mm。示例的，如图16所示为第一距离的变化量L′与开关按钮2的释放量l之间的关系曲线，由图16可知，随着第一距离的变化量L′的变大，开关按钮2的释放量l逐渐变大，且开关按钮2释放率也逐渐变大，由此使开关按钮2在低水位时，释放量较小，在高水位时，释放量较大，从而提高了除湿机用水满报警装置的报警响应准确性。
综上，为了提高除湿机用水满报警装置的报警响应准确性，可以通过以下两个特征进行改进：
第一个特征：随着支架4旋转角度的逐渐增大，凸缘41与弹片3之间的触点至支架4旋转轴线的水平距离的变化率逐渐增大；
第二个特征：当浮子5上浮时，凸缘41与弹片3之间的触点至弹片3的固定端的距离逐渐减小。
本发明实施例除湿机用水满报警装置中可以具有上述两个特征中的一个，也可同时具有两个，在此不做具体限定。示例的，本发明实施例除湿机用水满报警装置同时具有上述两个特征时，即图14和图16叠加后得到图17，相比于图14所示曲线和图16所述曲线，叠加后得到的图17所示曲线在高水位时，开关按钮2释放量的变化量更大，灵敏度更高，报警相应准确性更高。由此，即使在此叠加后的曲线上再次叠加上图13所示的曲线d，叠加后的曲线如图18所示，也满足开关按钮2在低水位时，释放量较小，在高水位时，释放量较大的要求。
在图2a所示的现有技术中，浮标06为桶状结构，具体的，如图4所示，桶状结构的上端封闭，下端开口，当浮标06的底部与集水箱05内的液面接触时，浮标06通过其内部储藏的空气产生浮力，由于浮标06的截面结构较小，导致浮标06产生的浮力较小，且由于整机振动，浮标06内部的空气可能以气泡的形式排出，导致浮标06产生浮力不稳定。为了避免上述问题，如图5所示，优选浮子5由泡沫材料制作，相比于现有技术中通过空气产生浮力，本发明采 用泡沫材料产生浮力，产生的浮力较大，且产生的浮力较稳定。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
