烹饪电器(例如微波炉)主要是通过用户直接拉门或按开门按键来开启，开门力的大小在25N以内，儿童很容易误触开门按键或拉手，轻按或轻拉即可打开烹饪电器，如此儿童很容易被烹饪电器内加热后的食物烫伤，存在很大的安全隐患。
为了解决上述问题，请参阅图1至图4，本申请实施方式提供一种烹饪电器1000的门锁装置100。烹饪电器1000包括箱体300，箱体300设有锁止部301。门锁装置100包括卡接件10及限定组件20。卡接件10可移动地设在门体200上，卡接件10包括卡钩11，卡钩11与锁止部301配合或脱离。限定组件20设于门体200，限定组件20包括转动件21，转动件21能够相对卡接件10转动而在锁定状态及解锁状态之间切换。其中，转动件21切换至解锁状态时避让卡接件10，卡接件10能够在第一方向D1上移动以与锁止部301脱离或配合；转动件21切换至锁定状态时，转动件21用于限定卡接件21在第一方向D1的移动位移，使卡钩11保持与锁止部301配合。
本申请的门锁装置100通过在门体200设置限定组件20，转动限定组件20中的转动件21能够使转动件21在锁定状态及解锁状态之间切换，在转动件21处于锁定状态的情况下，转动件21能够限定卡接件10在第一方向D1上移动位移，使卡钩11保持与锁止部301配合，从而保持门体200合在箱体300上，避免用户，尤其是没有成人陪同的孩童误操作而轻易打开门体200。当用户需要打开门体200时，需要先转动转动件21，以使转动件21处于解锁状态；卡接件10失去转动件21的限定作用后，此时再正常打开门体200(例如直接拽拉门体200或按开门按键)，卡接件10能够在第一方向D1上移动，以与锁止部301脱离，从而使得门体200从箱体300上打开。由于用户在打开门体200之前，需要先转动转动件21，即增加了打开门体200的步骤，能够避免由于误操作而轻易打开门体200，从而能够提高用户使用烹饪电器1000的安全性。
具体地，卡接件10可移动地设在门体200上。卡接件10包括相背的第一侧及第二侧，第一侧相较于第二侧更靠近转动件21。其中，第一方向D1是指自第二侧向第一侧的方向，第一方向D1的反方向是指自第一侧向第二侧的方向。下文中所提及的第一方向D1及第一方向D1的反方向也是如此，不再赘述。
在卡接件10包括卡钩11，卡钩11能够与锁止部301配合或脱离，以使卡接件10能够与锁止部301配合或脱离。其中，在卡接件10与锁止部301配合的情况下，卡钩11与锁止部301配合，能够保持门体200合在箱体300上；在卡接件10与锁止部301脱离的情况下，卡钩11与锁止部301脱离，能够将门体200从箱体300上打开。
需要说明的是，在卡接件10与锁止部301配合的过程中，或在卡接件10与锁止部301脱离的过程中，卡接件10均需要在第一方向D1上移动一定距离。具体地，如图2所示，锁止部301设有收容空间及挡片302，挡片302包括向靠近卡接件10一侧倾斜的斜面。在卡接件10与锁止部301配合的过程中，卡接件10中的卡钩11沿挡片302的斜面朝向收容空间移动，当卡钩11移动超过斜面靠近收容空间方向的尽头时，卡钩11落入收容空间中，以使卡钩11勾在挡片302上，从而实现卡钩11与锁止部301的配合，也即实现卡接件10与锁止部301的配合。可以理解，在卡钩11沿挡片302的斜面朝向收容空间移动的过程中，卡钩11在第一方向D1上移动了一定距离，也即卡接件10在第一方向D1也移动了一定距离；在卡钩11落入收容空间的过程中，卡钩11在第一方向D1的反方向上移动了一定距离，也即卡接件10在第一方向D1的方向也移动了一定距离。同样地，在卡接件10与锁止部301脱离的过程中，卡钩11需要先在第一方向D1上移动一定距离，即背离挡片302的方向移动，以脱离挡片302，随后卡钩11沿挡片302的斜面朝远离收容空间的方向移动，以使卡钩11脱离与锁止部301的锁合。可以理解，在这过程中，卡接件10也需要先向第一方向D1移动移动位移，才能够实现卡接件10与锁止部301脱离。
在一些实施例中，卡接件10可以包括两个卡钩11，此时锁止部301设有两个挡片302，分别与两个卡钩11配合，以将卡钩11与锁止部301锁合上。
在一些实施方式中，卡钩11的端部具有能够与挡片302配合的挂钩面。当用户对门体200施加拉力将门体200打开时，卡钩11的挂钩面沿着挡片302的端部滑动，直至卡钩11的端部高于挡片302的端部。
如图5及图6所示，图5及图6中的转动件21处于锁定状态。在一些实施例中，在转动件21处于锁定状态的情况下，转动件21的至少部分结构位于卡接件10在第一方向D1上的运动路径之内，且转动件21与卡接件10在第一方向D1上的间隔小于预定距离。其中，在卡接件10与锁止部301脱离的过程中，卡接件10在第一方向D1上移动的距离为预定距离。
由于转动件21的至少部分结构位于卡接件10在第一方向D1上的运动路径之内，转动件21能够限制卡接件10在第一方向D1上的移动位移，即卡接件10在第一方向D1上移动至转动件21抵触出后就不能够再继续移动。此外，由于转动件21与卡接件10在第一方向D1上的间隔小于预定距离，如此卡接件10在第一方向D1上移动的位移，不足以使卡接件10与锁止部301脱离，从而不能将门体200从箱体300上打开。
在一些实施例中，在转动件21位于锁定状态时，转动件21的至少一部分止抵卡 接件10以限制卡接件10的移动。示例地，在一些实施例中，转动件21包括抵触部211，在转动件21处于锁定状态的情况下，抵触部211位于卡接件10的上方，并且抵触部211与卡接件10止抵以限制卡接件10的移动。
特别地，在一些实施例中，在转动件21处于锁定状态的情况下，抵触部211位于卡接件10的上方，即抵触部211位于卡接件10在第一方向D1上的运动路径之内，在第一方向D1上抵触部211与卡接件10之间存在间隔，且间隔小于预定距离。如此，一方面能够使卡接件10保持与锁止部301配合；另一方面，由于抵触部211与卡接件10之间存在间隔，相较于抵触部211直接与卡接件10抵触，在转动转动件21时抵触部211与卡接件10之间不会产生摩擦，有利于用户更轻易的转动转动件21，从而以提升用户使用门锁装置100的体验感。
如图2、图3、图7及图8所示，图2、图3、图7及图8中的转动件21处于解锁状态。在一些实施例中，在转动件21处于解锁状态的情况下，转动件21位于卡接件10在第一方向D1上的运动路径之外。如此，在转动件21处于解锁状态的情况下，转动件21不能限制卡接件10在第一方向D1上的移动位移，即卡接件10能够在第一方向D1上移动，从而能够使卡接件10与锁止部301配合或脱离。
请参阅图3及图4，在一些实施例中，限定组件20还可以包括传动件22及施力件23，施力件23通过传动件22与转动连接，并且施力件23能够相对门体200转动，以带动转动件21转动。如此用户可以通过转动施力件23来间接转动转动件21，以使转动件21在解锁状态及锁定状态之间切换。
具体地，请参阅图3及图4，在一些实施例中，传动件22的一端与转动件21固定连接，另一端与施力件23固定连接。其中，传动件22与转动件21及施力件23的连接方式包括但不限于卡接、螺纹锁合、粘胶连接等，在此不作限制。例如，在一个例子中，传动件22的一端伸入转动件21的安装孔212内，并且与转动件21的安装孔212过盈配合，以使传动件22能够与转动件21固定连接；传动件22的另一端伸入施力件23的安装孔(图未示)内，并与施力件23的安装孔过盈配合，以使传动件22能够与施力件23固定连接。
请参阅图3及图4，在一些实施例中，限定组件20还可以包括支座24及第一弹性件25。支座24设在门体200上，第一弹性件25的两端分别与支座24和转动件21连接。在转动件21处于解锁状态时，第一弹性件25用于对转动件21提供朝向锁定状态转动的回复力。
具体地，支座24位于施力件23靠近转动件21的一侧，传动件22的一端与转动件21连接，另一端穿过支座24与施力件23连接。第一弹性件25套设于传动件22，且第一弹性件25的第一弹臂与支座24连接，第一弹性件25的第二弹臂与转动件21连接。在转动件21处于解锁状态的情况下，第一弹性件25发射弹性形变，第一弹性件25用于对转动件21提供朝向锁定状态转动的回复力。如此在转动件21转动至解锁状态后，第一弹性件25能够对转动件21提供回复力，以使转动件21自动转动至锁定状态，从而能够避免用户在使用后忘记将转动件21转动回锁定状态，有利于进一步地提高用户使用门锁装置100的安全性。
请参阅图3及图4，在一些实施例中，门锁装置100还包括限位组件30。限位组 件30设于门体200。限位组件30具有限制状态和避让状态，卡钩10与锁止部301(如图2所示)分离且转动件21位于解锁状态时，限位组件切换至限制状态以限制转动件21由解锁状态转动至锁定状态；限位组件30切换至避让状态时，限位组件30避让转动件21的转动。
由于在关门的过程中，即在卡接件10与锁止部301配合的过程中，卡接件10需要在第一方向D1移动才能够正常完成卡接件10与锁止部301的配合。在卡接件10与锁止部301分离时，若转动件21在第一弹性件25的回复力的作用下转动至锁定状态，那么用户需要先将转动件21转动至解锁状态后，再关门才能够使卡接件10与锁止部301配合。然而，在本实施例中，一方面，由于在卡钩10与锁止部301分离且转动件21位于解锁状态时，限位组件30切换至限制状态以限制转动件21由解锁状态转动至锁定状态，如此用户可以直接关门，无需再转动转动件21，从而有利于提高用户使用门锁装置100的便捷性；另一方面在限位组件30切换至避让状态时，限位组件30避让转动件21的转动，如此转动件21能够在锁定转动及解锁状态之间自由切换。
具体地，在一些实施例中，请参阅图3及图4，限位组件30包括限位块31。限位块31能够相对门体200移动以在第一位置及第二位置之间切换，第一位置相较于第二位置更靠近卡接件10。如图2及图3所示，在限制状态，限位块31位于第一位置，且限位块31与转动件21抵触；如图5至图8所示，在避让状态，限位块31处于第二位置以避让转动件21的转动。需要说明的是，在一些实施例中，当限位块31位于第二位置时，限位块31位于转动件21的转动路径之外。如此在限位块31位于第二位置时，不会阻挡转动件21转动，以使转动件21能够在解锁状态及锁定状态之间切换。
在一些实施例中，门体200开设有导向槽，限位块31靠近门体200的一侧设有能够与导向槽配合的结合件314，限位块31在第一位置及第二位置之间切换时，结合件314能够在导向槽内移动。
在一些实施例中，限位块31位于卡接件10的一侧，卡接件10移动时推动限位块31移动以使得限位块31在第一位置和第二位置之间切换。具体地，如图7及图8所示。图7及图8为门体200合在箱体300，且转动件21处于解锁状态时，门锁装置100个构件的示意图。此时，卡接件10与锁止部301配合且转动件21处于解锁状时，卡接件10能够在第一方向D1上的移动。限位组件30处于避让状态，即限位块31处于第二位置。若此时拉动门体100，卡接件10能够在第一方向D1上的移动，以与锁止部301脱离，同时卡接件10在移动时能够推动限位块31移动，限位块31能够从第二位置移动至第一位置。如图2及图3所示，图2及图3为打开门体200的情况下，门锁装置100个构件的示意图。此时，卡接件10与锁止部301分离且转动件21处于解锁状时，卡接件10能够在第一方向D1上的移动。限位组件30处于限制状态，即限位块31处于第一位置，限位块31限制转动件21向锁定状态转动。在关门的过程中，卡接件10需要在第一方向D1上的移动，才能与锁止部301配合，同时卡接件10在移动时能够推动限位块31移动，限位块31能够从第一位置移动至第二位置。
请参阅图3及图4，在一些实施例中，限位组件30还可以包括固定件32及第二弹性件33。固定件32与门体200固定连接，并设于限位块31远离卡接件10的一侧。第二弹性件33用于弹性连接限位块31及固定件32，在限位块31位于第二位置的情况下， 第二弹性件33能够发生弹性形变，以对限位块31提供朝向第一位置移动的回复力。
具体地，固定件32固定在门体200上，并位于限位块31远离卡接件10的一侧。限位块31包括第一面311、第二面312及第三面313。第二面312连接第一面311及第三面313，且第一面311相较于第三面313更靠近转动件21，第二面靠近固定件32。第二面312上设有第一配合件315，第三面313上设有第二配合件316。第二弹性件33的一端与固定件32靠近限位块31的一侧抵接，另一端与第一配合件315配合，以使限位块31弹性与固定件32弹性连接。
请结合图2及图3，图2及图3为打开门体200的情况下，门锁装置100中各构件的示意图，此时限位组件30处于限制状态，即限位块31位于第一位置时，限位块31的第一面211与转动件21抵触，以限制转动件21转动至锁定状态。若此时用户关闭门体200，在卡接件10与锁止部301配合的过程中，卡接件10在第一方向D1上移动，与位于第一位置的限位块31抵触后，能够推动限位块31，即给限位块31施加一个朝向固定件32的作用力，以使限位块31移动至第二位置(如图7及图8所示)。当限位块31移动至第二位置时，设于限位块31与固定件32之间的第二弹性件33被压缩，第二弹性件33能够对限位块31提供朝向第一位置移动的弹性回复力。
进一步地，在一些实施例中，请参阅图3、图4及图9，限位组件30还可以包括用于连接固定件32和限位块31的连接件34。固定件32包括支撑部321及导引部322，支撑部321与连接件34配合或脱离。导引部322设有连通的第一导槽3221和第二导槽3222。其中，在卡钩10与锁止部301脱离的过程中，连接件34脱离支撑部321，并在第二弹性件33的驱动下沿第一导槽3221朝接近卡接件10的方向运动，以带动限位块31移动至所述第一位置；在卡钩10与锁止部301进行配合的过程中，卡接件10推动限位块31和连接件34沿第二导槽3222朝远离卡接件10的方向运动后，限位块31在第二弹性件33的回复力作用下带动连接件34下落，以重新被支撑部321支撑。
在一些实施例中，支撑部321设有支撑槽3211，导引部322中的第一导槽3221及第二导槽3222分别位于支撑部321的两侧，并与支撑槽3211连通。在限位块31位于第二位置时，连接件34支撑在支撑槽3211内。
具体地，在一些实施例中，连接件34包括相背的第一端及第二端，第一端设有第三配合件343，第二端设有凸起部344。其中，第三配合件343与限位块31的第二配合件316配合，以使连接件34的第一端固定连接在限位块31上，从而连接件34与限位块31能够联动。连接件34的凸起部344能够在第一导槽3221及第二导槽3222内移动，在限位块31位于第二位置时，凸起部344能够被支撑在支撑槽3211内。
示例地，如图2、图3、及图5至图9所示，其中，图5及图6为在卡接件10与锁止部301配合且转动件21处于锁定状态的情况下，门锁装置100中各构件的示意图；图7及图8为在卡接件10与锁止部301配合且转动件21处于解锁状态的情况下，门锁装置100中各构件的示意图；图2及图3为在卡接件10与锁止部301脱离的情况下，门锁装置100中各构件的示意图。在卡接件10与锁止部301配合且转动件21处于锁定状态的情况下，转动件21处于锁定状态，连接部34的凸起部344被支撑在支撑槽3211内，且限位块31处于第二位置，第二弹性件33对限位块31施加朝向第一位置移动的回复力。此时若用户拉动门体200，由于转动件21处于锁定状态，即转动件21 至少部分位于卡接件10在第一方向D1上运动路径之内，转动件21限制了卡接件10在第一方向D1上的移动位移，因此卡接件10不能够与锁止部301脱离，也无法将门体200从箱体300上打开。当用户通过旋转施力件23以间接转动转动件21，以使转动件21能够转动至解锁状态，也即转动转动件21至卡接件10在第一方向D1上运动路径之外，此时再拉动门体200，卡接件10能够正常在第一方向D1上运动，在卡接件10移动时能够推动限位块31移动，限位块31能够带动连接件34朝远离卡接件10的方向移动，如此凸起部344能够离开支撑槽3211，在第二弹性件33回复力的作用下，限位块31能够给凸起部344施加朝向卡接件10的作用力，在该作用力的作用下凸起部344能够沿第一导槽3221朝接近卡接件10的方向运动，以带动限位块31移动至第一位置，即使限位组件30切换至限定状态。处于第一位置的限位块31能够与转动件21抵触，以阻挡转动件21回到锁定状态。当用户关闭门体200，卡接件10与锁止部301配合的过程中，卡接件10在第一方向D1上运动，在卡接件10移动时能够推动限位块31移动，限位块31能够给凸起部344施加远离卡接件10的作用力，在该作用力的作用下凸起部344能够沿第二导槽3222朝远离卡接件10的方向运动，以重新被支撑部321的支撑槽3211支撑，同时带动限位块31回到第二位置，即使限位组件30切换至避让状态。此时限位块31位于转动件21转动的路径之外，转动件21在第一弹性件25回复力的作用下，能够转动回到锁定状态。如此在能够打开门体200时，必须要先转动转动件21才能够使卡接件10与锁止部301的脱离，能够避免由于误操作而轻易打开门体200，从而能够提高用户使用烹饪电器1000的安全性；并且在关闭门体200时无需再次转动转动件21，转动件21也能够在卡接件10与锁止部301再次配合时，自动恢复至锁定状态，从而有利于提升用户使用门锁装置100的便捷性。
请参阅图9，在一些实施例中，第二导槽3222设有朝向支撑槽3211倾斜延伸的导引面3212以将连接件34导引至支撑槽3211。如此有利于在卡钩11与锁止部301进行配合的过程中，连接件34能够顺利沿从第二导槽3222移动至支撑槽3211内。
请参阅图10，在一些实施例中，门锁装置100还包括第三弹性件40，第三弹性件40分别与卡接件10和门体200相连，第三弹性件40朝向卡接件10施加回复力使得卡接件10朝向锁门位置移动，在锁门位置卡钩11与锁止部301配合。具体地，如图2所示，在卡接件10与锁止部301配合的过程中，卡接件10中的卡钩11沿挡片302的斜面朝向收容空间移动，当卡钩11移动超过斜面靠近收容空间方向的尽头时，第三弹性件40朝向卡接件10施加回复力使得卡接件10朝向锁门位置移动，即使卡钩11落入收容空间中，以使卡钩11勾在挡片302上，从而实现卡钩11与锁止部301的配合。
请参阅图1至图3，本申请实施方式还提供一种烹饪电器1000。烹饪电器1000包括门体200、箱体300及上述任意一项实施例中所述的门锁装置100。门体200安装于所述箱体300，门锁装置100中的设于门体200，箱体300设有锁止部301。
本申请的烹饪电器1000，通过在门体200设置门锁装置100，在门锁装置100中的转动件21处于锁定状态的情况下，转动件21能够限定卡接件10在第一方向D1上移动位移，使卡接件10保持与锁止部301配合，从而保持门体200合在箱体300上，避免用户，尤其是没有成人陪同的孩童误操作而轻易打开门体200，从而能够提高用户使用烹饪电器1000的安全性。
具体地，请结合图10，在一些实施例中，门体200包括主体201、门封202及门窗203，限定组件20设于主体201。门封202设于主体201靠近箱体300的一侧，门锁装置100的固定件32设于门封202，门窗203设于主体201远离箱体300的一侧，门锁装置100的施力件23位于门窗203远离主体201的一侧，施力件23与转动件21相连。需要说明的是，在烹饪电器1000的使用过程中，用户能够对设于门窗203远离主体201一侧的机构进行操作。由于在本实施例中，施力件23位于门窗203远离主体201的一侧，用户可以直接对施力件23进行操作。
请参阅图1及图11，在一些实施例中，烹饪电器1000还可以包括阻挡件400。阻挡件400设于门窗203远离主体201的一侧，并位于施力件23的转动路径上，阻挡件400用于限制施力件23的转动角度以将转动件21限制于所述解锁状态。具体地，在用户不想使用限定组件20时，即用户想在卡接件10与锁止部301锁合的情况下，转动件21始终保持在解锁状态时，用户可以先通过转动施力件23将转动件21转动至解锁状态后，将阻挡件400插入门窗203的安装槽中，使阻挡件400位于施力件23的转动路径上，以阻挡施力件23转动，从而阻挡转动件21转动。当用户想使用限定组件20时，用户只需要将阻挡件400从安装槽中取下，限定组件20即可正常使用。如此只需要简单的操作，用户即可根据自身需求选择是否需要限定组件20正常使用，有利于提升用户使用门锁装置100的便捷性。
