[0061] 进一步地， 如图 4所示， 本发明实施例还提供了洗碗机， 其包括机体、 转动安 装于机体上的机门 3和上述的洗碗机门锁机构， 机体包括机壳 （图未示） 、 设于 机壳内的内胆 5和设于内胆 5上的内胆加强筋 1， 锁体组件 2紧固安装于内胆加强 筋 1上， 锁舌 4紧固安装于机门 3上。 本发明实施例提供的洗碗机， 由于采用了上 述的洗碗机门锁机构， 故， 在机门 3厚度设计薄之后仍可保证洗碗机在洗涤过程 中的密封可靠性和使用安全可靠性， 从而利于机门 3的薄化设计。
[0062] 具体地， 如图 4和图 5所示， 机门 3包括靠近内胆 5的内门 31和位于内门 31外侧的 外门组件 32， 外门组件 32包括外门 322和位于外门 322上方的控制面板 321， 锁舌 4具体安装于内门 31与控制面板 321之间或者安装于内门 31上。 作为本发明实施 例的一较佳实施方案， 锁舌 4包括安装板 41和凸设于安装板 41上的插杆 42， 钩体 421设于插杆 42之远离安装板 41的端部。 安装板 41通过螺钉安装于内门 31与控制 面板 321之间， 插杆 42凸露于内门 31上， 由于锁舌 4的安装不会造成内门 31上有 明显的缺口， 故， 使得洗涤水等液体不容易流进内门 31与控制面板 321之间， 进 而确保了电子元件不易进水。
[0063] 本发明实施例提供的洗碗机门锁机构的工作原理如下：
[0064] 如图 2所示， 在机门 3处于打幵的状态下， 锁舌 4和锁体组件 2处于相互分离的状 态， 锁体组件 2内各部件处于初始状态 （扭簧 23和弹性件 25均未被压缩） ， 杠杆 26的第一支臂 262在弹性件 25的支撑下抵顶于控制幵关 24上， 此吋， 控制幵关 24 向主控制电路板板反馈机门 3处于打幵的信息， 以确保洗碗机的控制电路处于断 幵状态， 保证了产品使用的安全可靠性。
[0065] 如图 1所示， 在机门 3处于关闭的状态下， 锁舌 4处于卡插于锁体组件 2内的状态 ， 钩体 421卡于限位支杆 222与限位抵挡部 2132之间， 扭簧 23和弹性件 25都处于 被压缩状态， 且扭簧 23的弹性回复力使摆杆 22将钩体 421抵顶锁紧； 杠杆 26在摆 杆 22的抵顶作用下压缩弹性件 25并脱离控制幵关 24， 此吋， 控制幵关 24向主控 制电路板板反馈机门 3处于关闭的信息， 以使洗碗机的控制电路可导通， 保证了 产品的功能使用正常性。
[0066] 在幵、 关门过程中， 锁舌 4的钩体 421卡于限位支杆 222与推动支杆 223形成的卡 槽 220内， 且在推动或拉动锁舌 4吋锁舌 4会使摆杆 22环绕转轴 215转动， 摆杆 22 在转动过程中其连接支杆 221可压缩扭簧 23， 从而使得扭簧 23两端的夹角角度变 小。 如图 3所示， 为扭簧 23处于最大压缩的状态， 此吋， 如果继续推动或者拉动 锁舌 4， 扭簧 23的回复弹性力可辅助推动锁舌 4向锁紧或分离状态移动。
[0067] 以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的 精神和原则之内所作的任何修改、 等同替换或改进等， 均应包含在本发明的保 护范围之内。
