Description

带可拆磨豆装置的自动咖啡机
技术领域
本发明涉及咖啡或类似饮品的酿造设备技术领域， 特别是涉及一种带可拆磨豆装置的自 动叻口 11非机。
背景技术
市场上， 带有磨咖啡豆装置的自动咖啡机， 其研磨组件的固定方式有两种：
一种是通过紧固件固定在咖啡机机体上， 不能被用户方便地拆卸， 当磨豆机构发生堵粉 或者磨豆机构需要清洁时， 往往需要拆开整机才能进行， 这极大的损害了带磨豆装置的自动 咖啡机的使用体险；
另一种是通过一定的方式锁紧在咖啡机机体上的， 用户可通过一定的方式松开该豆箱组 件， 但其豆箱组件底部的开口不能封闭， 当用户取下该研磨组件时， 残余在豆箱组件里的咖 啡豆会落下， 弄脏用户的厨房地面， 用户只能通过翻转咖啡机的方式先倒干净豆箱组件中的 咖啡豆， 再取下豆箱组件， 操作使用不够方便。
同时，现有的带有磨豆装置自动咖啡机其磨豆室的出粉通道和清渣盘的设置方式有两种， 一种是把出粉通道设置在磨豆室的侧面， 清渣盘与出粉通道的起始部分开口处没有交集， 该 设置中因为咖啡豆被磨成咖啡粉后不能直接掉入出粉通道的起始部分开口处， 只能通过后面 磨出来的咖啡粉推前面磨出来的咖啡粉的方式来形成咖啡粉在出粉通道中的运动， 因此始终 会形成咖啡粉在出粉通道中残留，同时清渣盘不能防止出粉通道的起始部分开口处发生堵粉； 另外一种把出粉通道设置在磨豆室的底部， 其声称咖啡粉是通过重力直落的， 但同样的不能 防止出粉通道的起始部分开口处发生堵粉。
用户对带磨豆装置的咖啡机产品的智能特性提出了较高的要求， 因此设计出智能化、 易 于维护的咖啡机显得尤为必要。
