背景技术
干衣机主要由门、外壳、放置衣物的滚筒、风路、加热元件、控制系统等组成，目前，除了用热泵系统干燥衣物的干衣机以外，其他都是用电热元器件加热的方式来干燥衣物；即环境温度的空气经过加热元件变成高温气体进入滚筒，高温干燥空气和滚筒里面的湿衣物发生热交换，变成温度相对较低的湿热空气排出滚筒的过程，经过一定时间的循环，衣物即可以达到干燥效果。
由于干衣过程与洗衣过程不同，在执行干衣程序时，滚筒内不存水，所以在干衣程序执行期间，用户可以打开干衣机门取放衣物。一般情况下，在干衣机工作过程中，门体处于解锁状态，可以随时打开。但是，当干衣机内的衣物过多时，干衣机门会被顶开，影响干衣过程正常进行。

参见图6至图8，锁合部内设置有卡爪32，卡爪32与锁体31转动连接，当门钩插入锁合部，卡爪32能够与门钩卡接，以防止门钩脱出。可选地，锁体31上设置有支撑轴，卡爪32与支撑轴之间通过扭簧连接。卡爪32的一侧设置有滑块33，滑块33沿直线移动进而推动卡爪32的一端，使得卡爪32绕支撑轴转动。
锁体31上设置有解锁机构，解锁机构由电流控制，能够驱动滑块33移动。示例性地，解锁机构包括线圈341、移动件342和转接件343，线圈341与锁体31固定设置，在线圈341的驱动下，移动件342能够沿直线伸出和缩回，转接件343与移动件342固定连接，转接件343与滑块33之间斜面配合，进而驱动滑块33移动。
移动件342与压缩弹簧连接，在线圈341正向得电状态下，移动件342伸出，带动转接件343移动，转接件343将运动传递至滑块33，使得滑块33推动 卡爪32转动，进而将卡爪32锁紧，此时与滑块33连接的弹簧被压缩。
在突然断电状态下，由于压缩弹簧的作用，移动件342无法自行缩回，进而卡爪32一直卡紧门钩。在线圈341反向得电状态下，移动件342能够缩回。
解锁机构还包括解锁按钮，解锁按钮设置于干衣机的外壳10的表面上，通过按压解锁按钮，能够使得线圈341反向得电，线圈341驱动移动件342缩回，进而使得滑块33复位，卡爪32与门钩脱离，此时可打开门体20。解锁按钮的具体工作原理为相关技术。
干衣机还包括应急机构，应急机构包括触发件351、拉杆352、拉绳353和滑轴354，滑轴354与前面板11固定连接，拉绳353绕设过滑轴354，滑轴354对拉绳353起到导向和支撑作用，拉绳353的第一端与触发件351连接，第二端与拉杆352连接，拉杆352与锁体31连接。通过触发件351能够带动拉绳353移动，进而带动拉杆352移动，拉杆352上设置有凸出部3521，凸出部3521能够伸入锁体31内触发移动件342，使得移动件342缩回。
在一实施例中，触发件351包括滑钮和弹簧，滑钮与前面板11滑动连接，通过扳动滑钮，能够带动拉绳353拉动拉杆352，当松开滑钮时，在弹簧的作用下复位。
滑钮设置于前面板11的底部，防止儿童误碰。弹簧的设置，使得只有施加给滑钮一定的外力，才能够驱动滑钮滑动，为了防止儿童误碰，可以增大弹簧的刚度。
本申请实施例提供一种干衣机门锁控制方法，包括：
干衣机开始工作时，判断负载重量是否大于预设重量，若是，则控制门锁30处于锁定状态，否则，控制所述门锁30处于解锁状态。
若负载重量小于预设重量，表示衣物较少，则控制门锁30处于解锁状态，便于用户取放衣物；若负载重量大于预设重量，表示衣物较多，则控制门锁30处于锁定状态，防止衣物顶开门体20。
其中，负载重量可以用现有的传感器检测，在此不再赘述。控制门锁30处于锁定状态，即控制线圈341得电，使得卡爪32与门钩锁合。控制门锁30处于解锁状态，即控制线圈341反向得电，使得卡爪32与门钩脱离。
本实施例中提到的控制门锁30状态，是在门体20关闭的情况下进行的，当门体20打开时，不存在控制门锁30状态。
在门锁30处于解锁状态且干衣机工作过程中，检测负载重量，并在负载重 量大于预设重量时，控制门锁30处于锁定状态。由于干衣机在工作过程中，用户可能向干衣机内添加衣物，使得负载重量产生变化，所以需要再次检测负载重量，并在衣物超过预设重量时，控制门锁30处于锁定状态，防止衣物顶开门体20。
检测负载重量可以是：检测门体20的状态，若门体20打开又在第一设定时长内关闭，则检测一次负载重量。在干衣机开始工作时，检测了一次负载重量，在干衣机工作过程中，可以检测门体20状态，若门体20打开，可能用户会添加或者取走衣物，在门体20打开又关闭之后，检测一次负载重量，以便于控制门锁30状态。
若门体20打开，且超过第一设定时长未关闭，则触发报警装置。之所以设置第一设定时长，是可能存在用户长时间打开门体20，不关门又不暂停干衣过程，会影响干衣效果。
在本实施例中提到的干衣机工作过程中打开门体20，是指并未暂停干衣程序，即在干衣程序运行过程中打开门体20。若干衣机接收到暂停指令，又检测到门体20打开，则超过第一设定时长也无需触发报警装置。
检测负载重量还可以是：每间隔第二设定时长检测一次负载重量，以便于及时获知负载重量的变化。若检测到负载重量大于预设重量，需在门体20关闭的情况下控制门锁30处于锁定状态。
一般情况下，在门锁30处于锁定状态且干衣机工作过程中，无需检测负载重量，干衣机可一直执行干衣程序至结束。
根据干衣机的实际配置，条件允许的情况下，在门锁30处于锁定状态且干衣机工作过程中，检测负载重量，并在负载重量小于预设重量时，控制门锁30处于解锁状态。因为随着干衣机的工作，衣物被烘干，衣物的重量降低，此时能够允许用户再添加衣物。
在门锁30处于解锁状态下，用户直接可拉开门体20，使得门钩与锁合部脱离。
在门锁30处于锁定状态且通电的情况下，通过解锁机构能够打开门锁30。即通过按压解锁按钮，能够控制线圈341反向得电，使得移动件342缩回，进而带动转接件343移动，使得滑块33在弹簧的作用下复位，进而卡爪32在扭簧的作用下旋转，脱离门钩。
在门锁30处于锁定状态且断电的情况下，通过应急机构能够打开门锁30。 即通过扳动滑钮，能够带动拉绳353拉动拉杆352，使得拉杆352上的凸出部3521伸入锁体31内触发移动件342，使得移动件342缩回，进而滑块33在弹簧的作用下复位，使得卡爪32在扭簧的作用下脱离门钩。
实施例二
为简便起见，仅描述实施例二与实施例一的区别点。区别之处在于，干衣机内设置有蓄电池，在干衣机工作过程中，若断电，通过干衣机内部的蓄电池为门锁30供电，使得门锁30处于通电状态，此时若门锁30锁定，可通过解锁机构打开门锁30。
在一实施例中，蓄电池不限于为门锁30供电，蓄电池可以为整个干衣机供电，以使得干衣程序继续进行。
干衣机上设置有指示灯，通过指示灯指示供电模式，用户根据指示灯的颜色即可获知是电源供电还是蓄电池供电，便于用户及时操作，在蓄电池供电的情况下，用户可及时停止干衣程序或者减少干衣时长，以防止蓄电池中的电量耗尽。
指示灯可通过颜色的不同，以指示不同的供电模式。
在干衣机工作过程中，若蓄电池中的电量耗尽，即干衣机断电，此时可通过应急机构打开门体20。
实施例三
为简便起见，仅描述实施例三与实施例一的区别点。区别之处在于，干衣机上设置有指示灯，通过指示灯指示门锁30的状态。用户根据指示灯即可获知门锁30的状态，便于用户进行操作。当用户获知干衣机处于解锁状态时，如有需要，可以打开门体20添加或者取走衣物。当用户获知干衣机处于锁定状态时，在不必须的情况下，不会打开门体20，在必须的情况下，可通过解锁机构打开门体20。
指示灯具有多种颜色，用户根据指示灯的颜色即可获知门锁30的状态。或者，可以设置多个指示灯，每个指示灯对应不同的状态，用户根据开启的指示灯即可获知门锁30的状态。
指示灯能够指示锁定状态和解锁状态，其中，锁定状态可以分为电池供电锁定状态和电源供电锁定状态，解锁状态可以分为电池供电解锁状态和电源供 电解锁状态，便于用户及时获知干衣机的工作情况。
本申请提出的干衣机门锁控制方法，在干衣机开始工作时，判断负载重量，若负载重量小于预设重量，表示衣物较少，则控制门锁30处于解锁状态，便于用户取放衣物；若负载重量大于预设重量，表示衣物较多，则控制门锁30处于锁定状态，防止衣物顶开门体。
本申请实施例还提供一种干衣机，采用上述的干衣机门锁控制方法进行控制。不仅便于用户取放衣物，还能够防止衣物顶开门体20，且在能够在紧急情况下通过应急机构开门，使得用户使用方便。
