下面参考附图描述根据本申请实施例的洗碗机200和洗碗机200的自动开门装置100。
参照图1-图4所示，根据本申请实施例的洗碗机200可以包括机体210、门体220和根据本申请实施例的自动开门装置100，门体220能够打开和关闭。例如，机体210可以具有洗涤腔230和与洗涤腔230连通的取放口240，门体220处于打开状态下，取放口240与外界连通，门体220处于关闭状态下，取放口240关闭。例如在洗碗机200对餐具进行洗涤过程中，门体220如图2所示处于关闭状态。在用户取放餐具时，门体220可以如图1所示与取放口240所在平面呈90°，使取放口240完全敞开。
此外，门体220还可以如图3和图4所示处于打开状态，以打开取放口240一定角度或预设距离，以使洗涤腔230通过取放口240与外界能够发生一定程度的空气对流。由此，在洗碗机200处于干燥阶段，通过自动开门装置100推动门体220打开，使洗涤腔230内的高温湿气能够通过取放口240快速排出至外界，以提高餐具的干燥效率，从而可以降低漂洗阶段的温度，以达到降低洗碗机200能耗的目的，且避免运行过程中开门高温喷水的安全隐患，同时实现更好的干燥效果。
如图5和图6所示，根据本申请实施例的洗碗机200的自动开门装置100可以包括：座体10、推动件20、驱动组件30和弹性件40。
具体而言，座体10可以安装于机体210，以将自动开门装置100安装于机体210。推动件20安装于座体10，且推动件20具有伸出状态和回缩状态。推动件20在伸出状态下比在回缩状态下伸出座体10的尺寸大，使得推动件20在伸出状态下比在回缩状态下伸出机体210的尺寸大。例如如图1所示，自动开门装置100设于机体210的顶部的前端，机体210设有挡边，座体10位于的挡边的后侧，挡边设有过孔260，推动件20在伸出状态下穿过过孔260，以与门体220相抵，而推动件20在回缩状态下不由过孔260伸出。
推动件20处于伸出状态下，能够与门体220相抵，以使门体220如图3和图4所示打开，从而使洗涤腔230可以通过取放口240与外界连通并进行空气对流。而推动件20处于回缩状态下，门体220可以如图2所示关闭取放口240。
如图6所示，驱动组件30在通电状态下能够驱动推动件20由回缩状态移动至伸出状态，以使推动件20推动门体220，使门体220由如图2所示的位置移动至如图3所示的位置，从而驱动门体220打开，洗碗机200具有自动开门功能，无需用户手动操作，使用更方便。当然，用户也可以根据实际情况需要手动开门。
在一些实施例中，如图1-图4所示，门体220的一端(例如图4所示的下端)与机体210可转动连接，推动件20处于伸出状态下能够如图4所示与门体220的另一端(例如图4所示的上端)相抵，以使门体220的另一端与机体210间隔开预设距离L，从而使门体220与机体210呈一定角度。
需要说明的是，门体220与机体210的配合结构包括但不限于可转动连接结构。例如在另一些实施例中，门体220可以整体相对于机体210平移以实现打开和关闭，推动件20处于伸出状态下可以推动门体220相对于机体210平移，以使门体220整体与取放口240所在平面平行且间隔开预设距离L。这里，预设距离L可以理解为推动件20处于伸出状态下，推动件20超出取放口240所在平面的尺寸。
根据本申请的一些实施例，预设距离L可以为80mm-120mm。预设距离过小，洗涤腔230与外界空气对流效果差，不利于提高干燥效率，预设距离过大，不利于门体220保持平衡。在上述距离范围内，干燥效率高、干燥效果好，能够显著降低能耗，且有利于门体220在与机体210间隔开预设距离的位置保持平衡，无需设置平衡铰链等其他控制门体220保持平衡的结构，有利于简化结构、降低成本。在一些具体实施例中，预设距离可以为80mm、90mm、100mm、110mm和120mm等。
在一些实施例中，门体220关闭时，门体220可以与取放口240所在平面平行，以利于密封取放口240。
此外，驱动组件30驱动推动件20移动以使门体220打开后，门体220通常需要保持在打开状态一段时间，例如在干燥阶段，门体220需要保持在如图3和图4所示的位置，以便对餐具进行充分干燥。
因此，根据本申请实施例的自动开门装置100还包括弹性件40，弹性件40与推动件20相配合，在门体220处于打开状态且驱动组件30处于断电状态下，弹性件40可以维持推动件20的伸出状态，从而使推动件20与门体220配合以使门体220保持在打开状态的位置，而不随驱动组件30断电而改变位置。
通过设置弹性件40，驱动组件30无需持续通电，有利于降低能耗，无需设置门体平衡铰链等复杂结构，弹性件40结构简单，成本低，有利于简化洗碗机200的结构，降低生产成本。且在需要关门时，门体220能够直接克服弹性件40的弹力并关闭取放口240，实现快速关门，操作更方便快捷。
根据本申请的一些实施例，如图1-图3所示，洗碗机200还包括门锁组件250，在推动件20处于回缩状态下，门锁组件250能够锁合门体220和机体210。例如，关门过程中，门体220可以与推动件20相抵并推动推动件20，以使推动件20由伸出状态移动至回缩状态。
在推动件20处于回缩状态下，弹性件40的弹力小于门锁组件250的锁合力。由此，在驱动组件30处于断电状态且门体220处于关闭状态下，门锁组件250不会在弹性件40的弹力作用下解锁，从而避免洗碗机200在洗涤餐具过程中门体220打开而导致液体泄漏。在驱动组件30处于通电状态下，驱动组件30则可以推动推动件20，以使推动件20克服门锁组件250的锁合力，打开门锁组件250，使门体220能够打开。
本申请对门锁组件250的具体结构不做特殊限制。
例如，在一些实施例中，门锁组件250可以为机械锁。具体地，机械锁包括设于门体220的锁扣和设于机体210的扣合部，锁扣能够与扣合部锁合和解锁。
再例如，在一些实施例中，门锁组件250可以包括磁性件(例如磁铁)和可磁吸件(例如铁片)，磁性件和可磁吸件中的一个设于门体220且另一个设于机体210，磁性件能够与可磁吸件磁性吸合以实现门锁组件250的锁合。
在本申请的一些实施例中，门锁组件250和自动开门装置100可以集成设置，以使结构更紧凑，装配更方便，并且推动件20推动门体220以克服门锁组件250的锁合力更容易。
根据本申请实施例的洗碗机200的自动开门装置100，驱动组件30驱动推动件20移动以实现自动开门功能，并且通过弹性件40维持推动件20的伸出状态，提高了洗碗机200的干燥效果和干燥效率，有利于降低漂洗阶段的温度，且驱动组件30无需持续通电，有效降低了能耗，提高了驱动组件30的使用寿命，同时无需设置门体平衡铰链等结构，简化了洗碗机200结构，降低了生产成本。
由于根据本申请实施例的洗碗机200的自动开门装置100具有上述有益的技术效果，因此根据本申请实施例的洗碗机200，驱动组件30驱动推动件20移动以实现自动开门功能，并且通过弹性件40维持推动件20的伸出状态，提高了洗碗机200的干燥效果和干燥效率，有利于降低漂洗阶段的温度，且驱动组件30无需持续通电，有效降低了能耗，提高了驱动组件30的使用寿命，同时无需设置门体平衡铰链等结构，简化了洗碗机200结构，降低了生产成本。
下面结合附图描述根据本申请实施例的洗碗机200的自动开门装置100。
在本申请的一些实施例中，如图5和图6所示，座体10具有导向通道11，推动件20可移动地安装于导向通道11内，以在导向通道11的导向作用下在回缩状态和伸出状态之间移动，防止推动件20发生偏移或错位而影响开门效果，推动件20移动更顺畅。
根据本申请的一些实施例，驱动组件30包括驱动电机31，驱动电机31具有活塞杆311，活塞杆311能够伸缩。在驱动电机31通电时，活塞杆311伸出并与推动件20相抵，以驱动推动件20移动至伸出状态。驱动组件30的零部件数量少，结构简单。
根据本申请的一些实施例，如图5和图6所示，驱动组件30包括：驱动电机31和传动件32。传动件32可转动地安装于座体10，驱动电机31在通电状态下能够驱动传动件32沿第一方向(例如逆时针方向)转动，使传动件32的一端(例如图5中所示的左端)与推动件20相抵，以驱动推动件20移动至伸出状态。驱动电机31通过传动件32驱动推动件20移动，使驱动电机31与传动件32的设置位置更灵活，且可以通过调节驱动电机31和推动件20分别与传动件32配合的力臂，有利于使结构更紧凑。
例如在如图5所示的示例中，座体10设有安装轴12，传动件32与安装轴12可转动配合。传动件32的一端适于与推动件20配合，驱动电机31与传动件32的另一端(例如图5中所示的右端)配合。传动件32的一端与转动轴线的间距小于另一端与转动轴线的间距，由此，驱动电机31只需驱动传动件32转动较小角度即可使推动件20移动所需距离并实现自动开门，传动件32的尺寸更小，驱动电机31、传动件32和推动件20位置更紧凑。
在本申请的实施例中，驱动电机31与传动件32的配合结构可以根据实际情况灵活设置。
例如，在一些实施例中，驱动电机31的输出端可以转动，且驱动电机31的输出端与传动件32传动配合，以驱动传动件32转动。
再例如，在一些实施例中，如图5和图6所示，驱动电机31具有活塞杆311，活塞杆311能够伸缩，以使活塞杆311能够与传动件32相配合，以驱动传动件32转动。由此，驱动电机31可以设于传动件32的一侧，以减小自动开门装置100的高度，有利于满足机体210上较小安装空间的安装需求。
根据本申请的一些实施例，如图5和图6所示，活塞杆311在驱动电机31通电时伸出且在驱动电机31断电时回缩，活塞杆311伸出时与传动件32的另一端相抵，以驱动传动件32转动。通过驱动电机31通断电即可控制活塞杆311的位置以传动件32的位置，控制更简单。并且，活塞杆311伸出时驱动传动件32转动，使活塞杆311与传动件32可以相抵配合而无需设置其他连接结构，结构更简单。
在一些实施例中，驱动电机31可以为电动马达。
根据本申请的一些实施例，如图5和图6所示，推动件20的外周面设有配合凸部21，弹性件40为套设于推动件20的螺旋弹簧，螺旋弹簧的一端与配合凸部21相抵，且螺旋弹簧的另一端与驱动组件30或座体10相连。推动件20能够对螺旋弹簧进行限位，且防止螺旋弹簧与推动件20脱离配合。
根据本申请的一些实施例，如图5和图6所示，弹性件40的一端与推动件20相连，且 弹性件40的另一端与传动件32的一端相连，在驱动电机31断电时，弹性件40能够驱动传动件32沿与第一方向相反的第二方向(例如顺时针方向)转动。
由于传动件32与弹性件40相连，传动件32沿第一方向转动过程中能够挤压弹性件40，以使弹性件40的变形量增大，弹性件40对推动件20的驱动力增大，推动件20能够在弹性件40和传动件32的共同作用下推动门体220，使开门更快捷。而门体220打开后，传动件32沿第二方向转动过程中，弹性件40的变形量减小，使弹性件40对推动件20的驱动力减小且能保持门体220平衡，由此在用户手动关门时，阻力感更小，能够快速关门。
在本申请的一些实施例中，如图5和图6所示，推动件20和驱动电机31设于传动件32的同一侧，例如如图5所示设于传动件32的前侧，能够有效缩短自动开门装置100前后方向的尺寸，使结构紧凑，占用空间小。
根据本申请的一些实施例，驱动组件30处于断电状态下，驱动组件30与推动件20脱离配合。例如如图5所示，传动件32的一端与推动件20脱离配合。由此，在门体220处于打开状态时，推动件20只受来自弹性件40的驱动力，用户关闭门体220时，只需要克服弹性件40的弹力，手动关门无阻力感，操作更容易，能够实现快速关门，实现开门关门无缝切换。
下面参考附图详细描述根据本申请的一个具体实施例的洗碗机200和自动开门装置100，值得理解的是，下述描述只是示例性说明，而不能理解为对申请的限制。
如图1-图4所示，洗碗机200包括门体220、机体210、自动开门装置100、门锁组件250和控制组件。门体220与机体210通过转轴连接，且门体220可绕转轴在0°-90°范围内旋转。机体210的顶部安装有自动开门装置100和门锁组件250。门锁组件250包括磁铁和铁片，门体220和机体210分别安装有磁铁和铁片。
如图5所示，自动开门装置100包括座体10、驱动电机31、传动件32、推动件20和弹性件40。驱动电机31与控制组件信号连接，控制组件根据预设程序控制驱动电机31通电和断电，例如在进入干燥阶段时控制驱动电机31通电，在门体220打开后控制驱动电机31断电。驱动电机31上设有活塞杆311，传动件32为绕座体10上的安装轴12可旋转的滑杆，弹性件40为预压缩弹簧。推动件20穿设于座体10的导向通道11内，且沿导向通道11可移动伸缩。驱动电机31未通电不工作的情况下，活塞杆311在初始位置未伸出，推动件20在弹性件40的作用下伸出到最前端，且传动件32在弹性件40的作用下与活塞杆311接触。
如图3、图4和图6所示，门体220打开且驱动电机31未通电时，推动件20在弹性件40的弹力作用下伸出到最前端。需要关门时，推动件20在门体220的推动下向后移动，弹性件40压缩，使磁铁和铁片吸合锁紧。如图2所示，门体220关闭且驱动电机31未通电时， 由于锁紧力大于弹性件40的弹力，门体220能够保持在关闭状态。
如图3、图4和6所示，门体220关闭且驱动电机31通电后，活塞杆311伸出，传动件32在活塞杆311的推动下绕安装轴12沿逆时针旋转，直到活塞杆311达到最大行程，此时传动件32的一端接触到推动件20的端面，并推动推动件20向前移动，推动件20克服锁合力使门体220打开。推动件20移动至限位位置时，实现门体220打开固定角度的效果。
如图3、图4和图5所示，门体220打开后，驱动电机31断电，活塞杆311在较短时间内回缩复位，传动件32在弹性件40的作用下沿顺时针转动，而推动件20在弹性件40的作用下维持伸出状态，门体220在推动件20的作用下维持打开状态不变，即门体220保持平衡，从而实现持续有效开门，同时避免驱动电机31持续通电，确保驱动电机31寿命。
其中，弹性件40的长度和预压缩的预紧力可以按照门体220保持平衡的最小力设计，在自动开门后，手动关门无阻力感，能够达到开门关门无缝切换。
