具体实施方式
为了便于理解本公开，下面将参照相关附图对本公开进行更全面的描述。附图中给出了本公开的较佳的实施例。但是，本公开可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本公开的公开内容的理解更加透彻全面。
以下结合附图对本公开的原理和特征进行描述，所举实例只用于解释本公开，并非用于限定本公开的范围。
实施例一
结合附图1-5所示，本实施例提供了一种门体2开关结构，包括具有开口的箱体1和铰装在开口处的门体2，当本实施例的门体2开关结构应用到洗碗机时，上述的箱体1即为箱式洗碗机的箱体1，同理，门体2为开闭洗碗机箱体1的门体2；结合附图2和3所示，本实施例的门体2底部与箱体1底部通过铰链结构铰接，以使得门体2和箱体1可枢转地相连以打开和关闭所述箱体1。
除箱体1和门体2外，本实施例的门体2开关结构还包括驱动机构4和拉绳组件5；驱动机构4用于拉动或者放松拉绳组件5，拉绳组件5分别与驱动机构4和门体2连接，以使得拉绳组件5带动门体2开闭，关于驱动机构4和拉绳组件5的具体结构形式会在下文中给出。
基于上述结构，发明人发现，现有的门体2在关闭时一般与水平面成90°夹角，当驱动机构4放松拉绳组件5后，门体2未必能够通过自重来打开，发明人所了解的一种做法是将箱体1开口设计呈倾斜状，以使得门体2在关闭状态时也是倾斜状态，进而能够通过自重来打开，但是该结构需要整个箱体1结构进行改进，而且门体2在关闭后始终会拉伸拉绳组件5，进而使得拉绳组件5的绳体12始终受力，影响其使用寿命。
因此发明人对门体2开关结构做出进一步的改进，新增了一种推动机构3，本实施例的推动机构3安装在箱体1的上部，其用于将门体2向远离箱体1的方向推动至预设位置，此时门体2与箱体1呈预设角度，在拉绳组件5放松状态下，门体2可以通过自身的重力打开，无需对箱体1结构进行改进，而且门体2在关闭状态下可以维持自身稳定，对拉绳组件5的拉力几乎可以忽略不计。
根据上述结构描述可知，本实施例提供的门体2开关结构在开门时，驱动机构4放松拉绳组件5，并且推动机构3使门体2与箱体1呈一倾角，使得门体2能够在重力作用下 自动开门；关门时，驱动机构4拉近拉升组件使门体2恢复关闭状态；实现了门体2的自动开闭，节约人力。
为了进一步优化结构，本实施例的门体2连接有连接板6，具体是在门体2内侧的左右分别连接有一个连接板6，连接板6一端与拉绳组件5的绳体12相连接，另一端与门体2内侧相连接。优选的，连接板6与门体2互成角度，该角度约为45度，设计连接板6的第一目的是为了减少绳体12的使用，增加结构稳定性。
结合附图3可知，为了保证门体2再关闭状态时与箱体1之间密封性，本实施例的门体2的开口处连接有外扩的门框7，而且在门框7设有供连接板6穿过的避让孔16，门体2开闭过程中，连接板6在避让孔16内运动，此时设计连接板6的第二目的是由于如果完全采用绳体12，势必会增加避让孔的长度，不仅不利于加工，而且也降低了门框7和门体2之间的密封性。
另外，为了便于取放，本实施例的驱动机构4的安装位置、拉绳和连接板6的长度被构造为：当门体2位于最大开启位置时，门体2与箱体1之间呈90°夹角或大于90°夹角，进而保证了门体2的开启角度，便于用户拿放物品。
下面对本实施例的推动机构3、驱动机构4和拉绳组件5的结构形式进行进一步的说明。
结合附图4所示，本实施例的推动机构3优选为包括至少一个直线往复运动装置，即推动门体2后，该推动机构3的推动部还能够收回，防止其影响门体2的关闭。
具体的，本实施例的直线往复运动装置包括导向件8、推动件9和第一驱动电机10；导向件8安装在箱体1上，功能类似于导轨；推动件9与导向件8相连接，具体是安装在导向件8上或者安装在导向件8内，并且可以沿着导向件8的预设方向来回运动；第一驱动电机10与导向件8相连接，连接方式优选为结构简单且驱动稳定的啮合连接，第一驱动电机10的正反转带动推动件9沿导向件8的预设方向来回运动。当然，本实施例的推动机构3的结构形式不限于此，只要是能够实现推动功能并且能够收回的推动装置均可应用到本实施例中，例如发明人所了解的气缸或者油缸等。
结合附图1-3所示，本实施例的拉绳组件5包括绕线轮11和绳体12；本实施例的绕线轮11与驱动机构4相连接，具体的是与下述的第二驱动电机相连接，绳体12缠绕在绕线轮11上，并与门体2相连接。本实施例的绕线轮11在驱动机构4的带动下卷绕或者释放绳体12，以实现绕线轮11与门体2之间绳体12长短的变化，进而打开或闭合门体2。
本实施例的驱动机构4包括第二驱动电机，第二驱动电机与拉绳组件5相连接；具体的，第二驱动电机的输出轴与上述的绕线轮11直接连接或者通过传动机构连接，将扭矩 传递给绕线轮11，以实现绕线轮11卷绕或者释放绳体12。
为了便于第二驱动电机和绕线轮11的安装，本实施例在箱体1底部还设有底座15，箱体1和底座15之间设有安装空间，第二驱动电机和绕线轮11位于该安装空间内。
另外，为了避免在开门或者关门过程中存在障碍物阻挡，损坏拉绳，本实施的门体2开关结构还设计有距离传感器13和控制装置(图中未示出)；距离传感器13与控制装置电连接；距离传感器13在感应区域内检测到障碍物信息时，控制装置向驱动机构4发送控制指令，以关闭第二驱动电机。优选的，本实施例的距离传感器13的感应区域覆盖门体2开门或关门路径所在的区域，或者两者重合，避免其他由于其他因素导致关闭第二驱动电机。
另外，为了进一步提高整体的安全性和可靠性，本实施例还具有用于检测第二驱动电机输入电流的电流检测装置(图中未示出)，电流检测装置与控制装置电连接；第二驱动电机的输入电流大于第一预设值时，或者是第二驱动电机的输入电流小于于第二预设值时，控制装置向第二驱动电机发送控制指令，以关闭第二驱动电机。该设计是由于，当关门完成或者有异物卡住时，第二驱动电机的负载将会增大，导致第二驱动电机的输入电流增大，当第二驱动电机输入电流大于第一预设值时，第二驱动电机停止动作，实现关门完成或关门保护。同理，在自动开门途中，若有障碍物阻挡，会使第二驱动电机负载降低，当第二驱动电机输入电流低于第二预设值时，第二驱动电机停止动作，实现开门保护。
具体的，本实施例的控制装置可以包括比较器和控制器，比较器与上述的电流检测装置和距离检测装置相连接，并且将处理后的数据发送给控制器，控制器基于该数据向上述的第二驱动电机发送控制指令，以关闭控制电机。当然，本实施例的控制装置可以是发明人所了解的任意一种控制装置，而比较器和控制器等也可以为发明人所了解的比较器和控制器，因此本实施例不对控制装置的具体电路和工作原理进行详细描述。
实施例二
本实施例提供了一种洗碗机，其具有如实施例一所述的门体开关结构，另外也具有实现洗碗机的其他功能部件，例如洗碗单元、控制单元(图中均未示出)等，这里不一一列举。
而除了上述结构外，本实施例的洗碗机还具有一感应元件，如图5所示，该感应装置14可以是红外感应装置、语音感应装置、面部识别感应装置、手势感应装置、触摸感应装置中的任意一种，其用于生成一个感应信号，洗碗机的控制单元可以基于该感应信号执行相应的动作。例如，感应装置14为语音感应装置时，通过语音识别后给主控单元，主控单元控制洗碗单元进行洗碗工作，实现洗碗机智能化和自动化。
