Description

咖 机
技术械
本发明涉及一种咖啡机，尤其涉及一种研磨器和冲泡容器都可拆 卸的咖啡机。 背景技术
现有的咖啡机大致分两大类：一类是将研磨和冲泡组合成一体的 自动冲泡咖啡机； 另一类是将研磨器、 冲泡器分离的分体式咖啡机。 如中国专利号： 02209573· X便公开了一种 "咖啡机的自动冲泡装置"， 其由磨豆器、 滤冲器、 驱动机构和供水机构组合而成。 但上述自动冲 泡咖啡机存在以下缺陷：
1、 滤冲器在冲泡咖啡后， 滤筒中存有咖啡渣， 为使咖啡机能自 动连续的完成冲泡， 必须设置一自动去除咖啡渣的机构。这样使得自 动冲泡咖啡机的结构十分复杂， 制造成^艮高。
2、 由于冲泡容器是不能拆卸的， 冲泡容器的清洗十分不方便。 使用者在更换不同口味咖啡时，会造成串味。 清洗不方便还会造成卫 ll¾
3、 此种咖啡机在冲泡时， 大量水蒸汽会进入咖啡出粉通道和研 磨器， 使咖啡粉受潮， 影响咖啡机的使用。
4、此种咖啡机的咖啡粉出粉量控制机构结构复杂， 制造成本高。
5、 此种咖啡机冲泡时的出水量控制机构复杂， 制造成本高。 6、 由于研磨器设于咖啡机中不可拆卸， 研磨器中残余的咖啡粉 很难清除， 当咖啡机需更换不同品种的咖啡豆时，很容易造成咖啡粉 串味，使得应用了上述研磨器的咖啡机， 不能适应使用者频繁更换的 场合或咖啡爱好者使用。
7、 现有的研磨器由于只采用一个研磨电机， 研磨电机停止后， 出粉通道中的咖啡粉就不能排出，使得上述研磨器中的咖啡粉很难被 排出干净。
再者， 现有的将研磨器、 冲泡器分离的咖啡机，在使用时， 需先 将咖啡豆在研磨器中研磨成咖啡粉，然后将咖啡粉放入冲泡器中进行 冲泡。此种咖啡机将研磨好的咖啡粉需用手工的方法放入冲泡器，使 用十分不便。 发明内容
为了克服现有技术中的缺陷， 本发明的目的在于： 提供一种结构 简单、 清洗方便、 工作可靠、 制造成本低， 并且适合使用者频繁更换 场所使用的咖啡机。
为了实现上述目的， 本发明的技术方案是这样实现的： 一种咖啡 机， 咖啡机壳体内设有研磨器、 沖泡容器和供水机构， 冲泡容器与供 水机构相连； 所述研磨器的出料口下方设有冲泡容器， 冲泡容器中设 有滤网， 冲泡容器通过可拆结构定位在咖啡机上。 由于冲泡容器通过 可拆结构定位在咖啡机壳体上， 在冲泡完咖啡后，取下冲泡容器便可 倒出咖啡渣。 而倒出咖啡渣工作采用手工操作， 可大大简化咖啡机的 结构， 使咖啡机结构简单， 制造成本较低。 由于本发明将研磨器和冲 泡容器都设在咖啡机中， 将咖啡豆放入咖啡机后，操作控制开关便可 完成磨豆和冲泡工作。 与研磨器和冲泡器分离的咖啡机相比，省去了 咖啡粉从研磨器中取出后手工将咖啡粉放入冲泡器的过程，使用也比 较方便。 由于冲泡容器通过可拆结构定位在咖啡机上，取下冲泡容器 便可进行清洗， 使得在更换不同口味咖啡时， 不会造成串味， 使用也 · 更卫生。
在本发明中， 所述的研磨器优选电动研磨器，研磨器的研磨盘由 研磨电机带动。 当然， 研磨器也可以是手动研磨器， 研磨器的研磨盘 由手柄带动。 只要将研磨器设于咖啡机中，研磨后的咖啡粉可方便的 进入冲泡容器便可完成本发明的目的。
在本发明中， 冲泡容器可采用多种可拆方式与咖啡机壳体连接， 可釆用将所述的冲泡容器插接于咖啡机壳体上；或冲泡容器通过螺紋 连接于咖啡机壳体上；或冲泡容器通过挂接的方式连接于咖啡机壳体 上， 只要冲泡容器与咖啡机间能方便的拆装连接结构都可以。
在本发明中， 所述的供水机构包括： 咖啡机的水箱、 加热容器、 相连在水箱与加热容器之间的出水管，连接在加热容器与沖泡容器之 间的出水管。 供水机构采用上述结构， 结构简单、 制造方便。 加热容 器也可釆用微型锅炉。
所述的加热容器可以为单根或多根管状加热容器 ,也可采用微型 锅炉加热。
在本发明中， 所述的研磨器出料口设有出料门。 出料门在研磨咖 啡粉时可防止咖啡粉飞散。 同时， 出料门可阻挡大量水蒸汽进入咖啡 出粉通道和研磨器， 防止咖啡粉受潮。
在本发明中， 所述的出料门可以是具有至少一瓣膜的橡胶门。 由 于橡胶门自身具有一定的弹性，在研磨咖啡粉时， 研磨器产生的气流 可压迫橡胶门自动打开。当研磨完成后，橡胶门在自身弹性的作用下， 将出料口封闭， 阻挡冲泡时大量水蒸汽进入咖啡出粉通道和研磨器。 本发明的橡胶门可采用具有一瓣膜的橡胶门； 当然，也可采用具有二 个瓣膜或多个瓣膜的橡胶门。 出料门采用橡胶门其结构十分筒单。
在本发明中，所述橡胶门的下端伸入或不伸入沖泡容器中这两种 情况都可以。橡胶门的下端伸入冲泡容器中时，抽插冲泡容器可触动 橡胶门， 碰散少量粘结于橡胶门旁的咖啡粉， 使研磨器工作时， 橡胶 门可方便的输出咖啡粉。 当橡胶门的下端不伸入冲泡容器中时， 通过 选择适当弹性的橡胶门瓣膜和控制研磨器产生气流的大小，来实现研 磨器工作时橡胶门方便的输出咖啡粉。
在本发明中，所述的出料门还可以是插入式电磁阀门或翻转式电 磁阀门。 出料门采用电磁阀门来实现开闭， 具有良好的密封性能。 插 入式电磁阀门和翻转式电磁阀门都具有良好的阻挡水蒸汽进入研磨 器和咖啡 4分出粉通道的功能。
在本发明中， 所述的咖啡机设有咖啡粉出粉量控制机构， 出粉量 控制机构中设有控制电机工作的工作时间调节器。供水机构中设有冲 泡出水量控制机构，冲泡出水量控制机构中设有控制加热容器工作的 工作时间调节器。 出粉量控制机构和冲泡出水量控制机构可协同工 作， 当然也可根据用户需要来进行调整。 出粉量通过工作时间调节器 调整电机工作时间来控制， 其结构十分简单。 冲泡出水量通过工作时 间调节器调整加热容器工作时间来控制， 其结构十分筒单。
作为优选， 在本发明中， 所述的水箱与出水管间设有止回阀， 加 热容器是管状加热容器， 管状加热容器与冲泡室相连， 沖泡室设于冲 泡容器的上方， 冲泡室上设有回汽管与水箱相连。 采用管状加热容器 便于通过控制加热时间来控制冲泡出水量。
在本发明中， 所述的咖啡机设有定时器。 其可根据用户的要求完 成定时冲泡咖啡的工作。 如设定某一时间， 咖啡机届时会自动冲泡所 需的咖啡。
所述研磨器中设有豆仓， 豆仓下设有磨体， 磨体中设有磨豆腔， 磨豆腔中设有研磨盘， 所述研磨盘包括转动研磨盘和静止研磨盘， 两 磨盘上均设有磨齿，研磨电机的转轴与转动研磨盘相连，磨豆腔设有 出粉口， 出粉口下设有出粉通道； 所述的研磨电机的转轴与转动研磨 盘间设有可拆式联轴器。
