具体实施方式
下面结合附图和实施方式对本公开的技术方案作相关描述。应当理解，此处所描述的实施例仅仅用以解释本公开，并不限定本公开。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。
实施例一
本实施例提供了一种洗衣机上盖自动开关控制装置，如图1所示，该控制装置可以包括控制器1以及连接于该控制器1的检测器2。
所述控制器1控制电机3顺时针转、逆时针转以及停转，以驱动上盖4打开、关闭或停在当前位置。
所述检测器2，设置为采集上盖4打开或关闭过程中上盖4与盘座之间或上盖4远离盘座的一侧的障碍物信号，将所述障碍物信号发送至所述控制器1。
可选地，该障碍物信号可以是指电机3转动过程中电机3内的线圈的电流信号。当上盖4打开或关闭过程中遇到障碍物时，电机3将堵转造成电机3线圈上的电流发生变化。检测器2可采集电机3线圈的电流信号，并将采集到的电流信号发送至控制器1。控制器1可以根据所接收的电流信号计算出电流值I的变化状况确定上盖4在打开或关闭过程中是否遇到障碍物，并在确定存在障碍物时将所述上盖4停在当前位置或回至初始位置。
可选地，所述洗衣机上盖自动开关控制装置还可以包括与控制器1连接的报警器5。在控制器1确认上盖4在打开或关闭过程中存在障碍物时，所述报警器5将发出声音警报，提醒用户移开障碍物。
基于上述洗衣机上盖自动开关控制装置，本实施例还提供了一种洗衣机上盖自动开关控制方法，如图2所示，该控制方法包括以下步骤。
在S10中，控制器1控制电机3驱动上盖4打开或关闭。
可选地，当控制器1控制电机3顺时针转动时，电机3驱动上盖4打开，当控制器1控制电机3逆时针转动时，电机3驱动上盖4关闭，当控制器1控制电机3停止转动时，电机3驱动上盖停止在当前位置。在需要打开或关闭上盖4时，控制器1发送命令信号给电机3，控制电机3顺时针转动或逆时针转动，以通过电机3驱动上盖4自动打开或关闭。上述仅为举例说明电机3的转动与上盖4的动作之间的关系。除此之外，当控制器1控制电机3顺时针转动时，电机3还可以驱动上盖4关闭，当控制器1控制电机3逆时针转动时，电机3驱动上盖4打开。
在S20中，检测器2采集上盖4与盘座之间或上盖4远离盘座的一侧存在的障碍物信号，并将障碍物信号发送至控制器1。
可选地，所述障碍物信号可以是指电机3转动过程中电机3内的线圈上的电流值I，检测器2采集电机3转动过程中电机3内的线圈上的电流信号，并将所测电流信号发送至控制器1，由控制器1对该电流信号进行数据处理。
在S30中，控制器1接收障碍物信号，确定上盖4与盘座之间或上盖4远离盘座的一侧是否存在障碍物。
控制器1接收电流信号并计算出相应的电流值I，并将电流值I与预设电流值Ia进行比较，其中预设电流值Ia可以是指上盖4正常关闭或打开过程中的电 机3内线圈上的电流值。上盖4打开或关闭过程中遇到障碍物时，电机3将发生堵转造成电机3线圈上的电流值会变大，因此如果I＞Ia，则上盖4打开或关闭过程中存在障碍物，如果I≤Ia，则在上盖4打开或关闭过程中不存在障碍物。
在S40中，控制器1确定在上盖4打开或关闭过程中存在障碍物时，控制电机3使上盖4停在当前位置或回至初始位置，并执行步骤S50中的操作；当确定在上盖4打开或关闭过程中不存在障碍物时，控制器1使上盖4继续打开或关闭并直至完全打开或关闭；
在确定在上盖4打开或关闭过程中存在障碍物时，控制器1控制电机3驱动上盖4停在当前位置或回至初始位置。可选地，当控制器1确定在上盖4打开或关闭过程中存在障碍物时，控制电机3驱动上盖4停在当前位置。可选地，当控制器1确认在上盖4打开或关闭过程中存在障碍物时，在控制电机3驱动上盖4停在当前位置的同时，发送命令信号给报警器5，报警器5将发出警报，提醒用户移开障碍物，以避免上盖4继续打开或关闭时因电机3持续堵转而烧坏电机3，以及继续关闭上盖4夹伤用户等。
可选地，报警器5发出的警报可为声音警报。
在S50中，在上盖4停在当前位置或回至初始位置T时间后，执行S10至S40中的操作。
给予用户一定的时间移开障碍物，而后继续打开或关闭上盖4并重复执行S10至S40中的操作，直至上盖4完全打开或关闭。在确定在上盖4打开或关闭过程中存在障碍物时，控制器1控制电机3驱动上盖4使该上盖停在当前位置，由于上盖4由当前位置回至初始位置并再次回到当前位置需要消耗时间T1，因此需要保证所述时间T大于等于T1。
实施例二
在实施例一的基础，该装置还可以包括角度测量器6，在执行实施例一中S10的操作之前，洗衣机上盖4自动开关控制方法还可以包括采用手动方式打开或关闭上盖4。
如图3所示，所述角度测量器6与控制器1连接，设置为实时采集上盖4与盘座之间的角度值A，并将采集得到的角度值A发送至控制器1。所述控制器1接收角度测量器6发送的角度值A并对该角度值A进行处理。
将所述上盖4当前打开或关闭的角度值设为β，在打开上盖4时，上盖4与盘座之间的角度值A即为上盖4打开的角度值β，即β＝A；在关闭上盖4时，上盖4关闭的角度值β＝90°-A。
通过控制器1计算出上盖4当前打开或关闭的角度值β，并将上盖4当前打开或关闭的角度β值与预设角度值α进行比较，并根据比较结果确定控制器1是否控制电机3驱动上盖4转动使该上盖4自动打开或关闭。其中预设角度值α可以是0°-90°之间任意值。可选地，该预设角度值α的范围为0°-30°，例如预设角度值为0°-15°中的任意值。
本实施例中，当β大于等于α时，控制器1将控制电机3驱动上盖4转动使该上盖4自动打开或关闭，。当β小于α时，继续采用手动的方式打开或关闭上盖4。采用上述方式使上盖4在打开一定角度之后采用自动方式继续打开或关闭，在自动打开或关闭上盖的功能开启后，可以通过报警器提醒用户挪开手指等，降低夹伤用户的可能性，还可以减少用户手动打开或关闭上盖4所使用的力。
实施例三
本实施例还提供一种非暂态计算机可读存储介质，存储有计算机可执行指 令，所述计算机可执行指令用于执行上述任意一种洗衣机上盖自动开关控制方法。
实施例四
本实施例还提供了一种设备，图5为该设备的硬件结构示意图，如图5所示，该设备可以包括：一个或多个控制器10，存储器20，图5中以一个控制器10为例。
该设备还可以包括：输入装置30和输出装置40。
所述设备中的控制器10、存储器20、输入装置30和输出装置40可以通过总线或者其他方式连接，图5中以通过总线连接为例。
存储器20作为一种非暂态性计算机可读存储介质，可用于存储软件程序、计算机可执行程序以及模块。控制器10通过运行存储在存储器20中的软件程序、指令以及模块，从而执行不同功能应用以及数据处理，可实现上述任意一种洗衣机上盖自动开关控制方法，例如，控制器10可控制电机3转动，可接收检测器2发送的障碍物信号，并分析该障碍物信号确定上盖4与盘座之间或上盖4远离盘座一侧是否存在障碍物等，还可以接收角度测量器6发送的角度值A，并对角度值A进行分析确定是否控制电机3驱动上盖4自动开关或关闭。
存储器20可以包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需要的应用程序。存储数据区可存储根据设备的使用所创建的数据等。此外，存储器20可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他非易失性固态存储器件。在一些实施例中，存储器20可选包括相对于控制器10远程设置的存储器，这些远程存储器可以通过网络连接至设备。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
输入装置30可用于接收输入的数字或字符信息，以及产生与设备的用户设置以及功能控制有关的键信号输入，例如，该输入装置30为洗衣机上的操作面板。输出装置40可包括显示屏等显示设备或者报警装置等声音输出设备，例如，该输出装置40为报警器5。
最后需要说明的是，本领域普通技术人员可理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来执行相关的硬件来完成的，该程序可存储于一个非暂态计算机可读存储介质中，该程序在执行时，可包括如上述方法的实施例的流程，其中，该计算机可读存储介质可以为磁碟、光盘、只读存储记忆体(ROM)或随机存储记忆体(RAM)等。
工业实用性
本实施例提供了一种洗衣机上盖自动开关控制装置及控制方法，可以解决在上盖打开或关闭过程中夹伤用户以及电机长时间堵转烧坏电机的问题，还可以降低误夹伤用户的可能性，节省手动打开或关闭上盖时所用的力。
