Description

自动产生泡沫牛奶的牛奶发泡装置
技术领域
本发明涉及一种制备蒸汽奶泡的牛奶发泡装置,尤其涉及一种自动产生泡沫牛奶的 牛奶发泡装置, 该装置可与咖啡机一起使用或集成到咖啡机中。 背景技术
喝咖啡时, 在咖啡中配上丝滑细腻的奶泡能增加咖啡的口味和质地, 且能起到很好 的装饰作用,奶泡是牛奶与空气细密混合的产物。产生泡沫牛奶的装置有多种结构形式。
其中一种是采用快速搅拌牛奶的方式生成泡沫牛奶的装置, 一般包括加热装置、基 座、 设置在基座上的容器体及容器盖, 加热装置一般设置在基座底部的容置腔内, 容器 体与基座能分离, 容器体内还设有搅拌头, 搅拌头内设有从动磁铁, 基座内部安装有驱 动搅拌头的驱动装置, 驱动装置包括驱动电机, 驱动电机的输出轴上安装有与从动磁铁 相匹配的驱动磁铁。 如公告号为 CN202287940U (专利号为 201120381977.4)的中国实用 新型专利 《一种奶液、 奶泡比例可调的打奶器》。 这种牛奶发泡装置结构涉及部件多、 结构复杂、 体积庞大且成本高, 另外不方便与咖啡机一起使用或集成到咖啡机中。
另外一种是在杯子中直接装入冷牛奶,利用直接连接在蒸汽管上的蒸汽棒喷嘴来制 备泡沫牛奶,如公告号为 CN201444867U (专利号为 200920009905.X)的中国实用新型专 利 《一种打奶泡装置》披露了这样一种打奶泡装置, 由外管、 出气管、 冷空气管、 调节 开关、 出气接头、 接头端盖、 蒸汽管和感温线组成, 蒸汽管通过出气接头和接头端盖连 接到出气管, 调节开关设置在出气管上端, 冷空气管和感温线沿轴向设置在出气管外周 缘, 两者错开一定角度, 外管沿轴向设置在出气管外端。 这种蒸汽棒喷嘴仅在端部设若 干的喷孔, 并且蒸汽管与蒸汽棒喷嘴之间的密封性不强, 喷出的蒸汽强度有限, 需借助 摇动奶杯, 倾斜奶杯, 增加牛奶与空气的接触面积, 以及调整喷嘴与牛奶的接触深度等 经验及技巧, 才能制做出较好质量的奶泡, 也就是说要想得到好的泡沫牛奶必须依赖操 作员的操作技巧, 而对于奶泡有高品质要求者通常认为, 不论操作者的经验或技巧如何 的运用, 以现有的喷嘴所制出的奶泡其膨胀度、 发泡度、 绵密度及柔润口感都嫌不足。
针对这一现状, 有人发明了奶泡制备操作方便的傻瓜式牛奶发泡装置, 如一公告号 为 CN201243958Y (专利号为 200820003777.3)的中国实用新型专利《自动吸牛奶发泡器》 披露了这样一种发泡器, 包括: 下部连接了该发泡器下盖的发泡器主体; 设置在该发泡 器主体上的蒸汽管接头; 连接在该发泡器主体上的牛奶供给管; 设置在该发泡器主体上 的独立的进空气胶塞; 由该发泡器主体、 蒸汽 管接头和发泡器下盖构成的各自独立的 混合腔, 真空腔和乳化腔, 其中, 蒸汽管接头将蒸汽管直接连接到该发泡装置上, 牛奶
- 1 - 确认本 供给管直接连接牛奶供给线, 该独立的进空气胶塞连通大气与该混合腔。使用本实牛奶 发泡器, 不再需要手持牛奶杯进行打奶泡, 可以防止烫伤并且简化了操作。但由于蒸汽 进口与牛奶进口两者彼此独立, 且蒸汽进口与直接正对真空腔的出口, 这样导致蒸汽在 真空腔中没有和牛奶及空气充分混合, 就快速通过混合腔的出口流出, 即蒸汽、 奶和空 气的混合物分别按照各自的速度及角度通过混合腔的出口进入乳化腔, 蒸汽、奶和空气 三者在真空腔中停留时间极其短暂, 造成这种发泡器蒸汽、奶和空气三者相互混合的时 间短, 故生产出的奶泡不够细腻, 口感较差。 发明内容
本发明所要解决的技术问题是针对上述现有技术现状而提供一种奶泡制备操作简 单且能使空气、 奶和蒸汽三者充分完全混合的自动产生泡沫牛奶的牛奶发泡装置, 该装 置制作的奶泡膨胀度、 发泡度、 绵密度及柔润口感俱佳。
本发明解决上述技术问题所采用的技术方案为:一种自动产生泡沫牛奶的牛奶发泡 装置,包括其内具有腔室的壳体,壳体的底部设有出口,壳体的侧部设有蒸汽供给通道、 牛奶供给通道和进空气通道;
其特征在于: 所述壳体内具有隔壁, 该隔壁将所述腔室内部分隔而形成供蒸汽、 奶 和空气的混合物在里面旋转流动混合的旋转混合区, 所述壳体的侧壁设有引射口, 该引 射口和出口之间通过所述旋转混合区相通, 所述蒸汽供给通道、 牛奶供给通道和进空气 通道均通过所述引射口与旋转混合区相通。
上述牛奶供给通道和进空气通道经由奶气混合通道后再与弓 I射口相通。这样牛奶和 空气能在进入旋转混合区前先充分混合, 进一步提高奶泡的质量。
上述壳体的侧部具有第一通道和第二通道, 所述引射口位于第一通道的底部, 所述 第二通道与第一通道连通, 所述第一通道内插设有蒸汽管接头, 蒸汽管接头的外周与第 一通道内周壁之间设有第一密封圈, 所述蒸汽供给通道位于蒸汽管接头内; 所述第二通 道内插设有进气插头, 进气插头的外周与第二通道内周壁之间设有第二密封圈, 所述进 空气通道设置在进气插头内,该进气插头将第二通道阻断并在位于进气插头内端的第二 通道内部形成奶气混合通道, 第二通道的侧部具有牛奶管接头, 所述牛奶供给通道位于 牛奶管接头内, 牛奶供给通道与奶气混合通道连通, 进气插头的侧壁上设有与进空气通 道相通的进气孔, 进气孔通过进气插头与第二通道之间的间隙与牛奶供给通道连通。其 为一种具体形成蒸汽供给通道、牛奶供给通道、进空气通道和奶气混合通道的结构方式, 前述结构具有组装方便, 且便于与咖啡机内部组件进行连接。
上述进气插头的后端具有辅助通道, 辅助通道和进空气通道之间通过隔断壁阻断, 辅助通道的侧壁上开有用以连通辅助通道和牛奶供给通道的辅助调节孔。该进气插头的 结构能实现对进奶量的多少进行调节, 从而实现对奶泡细腻程度的控制, 调节时只需转 动进气插头, 通过辅助调节孔与牛奶供给通道出口位置的对齐程度控制实现, 当辅助调 节孔与牛奶供给通道出口位置完全对齐, 进奶量最大, 而辅助调节孔与牛奶供给通道出 口位置错位越多则进奶量越少。
上述第二通道的外端面上设有外凸的卡扣脚, 进气插头上供卡扣脚插入的卡槽, 在 卡扣脚插入卡槽并旋转一个角度的状态下, 所述卡扣脚卡扣在卡槽后部, 进气插头的外 周壁具有向外延伸的扳手部。 通过卡扣脚与卡槽的卡配实现进气插头与第二通道的固 定, 该固定方式便于装卸进气插头。
上述蒸汽管接头的头端外周面为外圆锥面, 第一通道的底部的内周面也为内圆锥 面, 所述外圆锥面和内圆锥面之间形成锥形区, 所述引射口和奶气混合通道通过该锥形 区连通。锥形区的设置能让牛奶和空气的混合物在锥形区内形成涡流, 使该混合物快速 通过引射口与蒸汽混合。
进一步改进, 上述壳体的顶部设有咖啡供给通道, 该咖啡供给通道一直向下延伸并 从所述出口的中部穿出。 设置咖啡供给通道能使该发泡装置同时完成咖啡与奶泡的混 合, 客户使用非常方便, 只需要将杯子放在出口下方, 就可一键式完成一咖啡、 奶泡或 咖啡加奶泡 (如拿铁、卡布奇诺), 可任意选择, 传统的发泡装置如要制作卡布奇诺咖啡, 需要先通过蒸汽打奶泡, 然后再煮咖啡, 其中打奶泡需要非常专业的人员才可以完成, 而且打好的奶泡还要在倒在咖啡中, 过程非常繁琐; 我们此结构非常简单可以讲是傻瓜 式的, 不需要任何专业的打奶技术就可以得到非常高品质的奶泡, 通过结构的优化, 使 咖啡和奶泡实现了同一出口处流出, 解决客人二次操作的麻烦, 非常简便。
上述壳体由底座和上盖可脱卸的连接而成, 所述出口设置在底座的底面上, 所述蒸 汽供给通道、 牛奶供给通道和进空气通道设置在底座侧部, 所述隔壁及咖啡供给通道则 设置在上盖的底面上。 前述壳体结构不但便于组装, 而且还方便清洗。
上述隔壁呈圆环状, 且圆环状的隔壁的下端面与底座的内底面之间具有供蒸汽、奶 和空气的混合物通过的间距,该圆环状的隔壁的外周面与底座的内周壁之间的空间形成 所述旋转混合区。前述隔壁结构为隔壁的一种最优方案, 该隔壁结构使旋转混合区成完 整的圆环状, 便于混合物在旋转混合区里旋转多圈, 从而形成细腻的奶泡。
当然上述隔壁也可呈螺旋状,且螺旋状的隔壁的下端面与底座的内底面之间具有供 蒸汽、奶和空气的混合物通过的间距, 该螺旋状的隔壁围成的螺旋状区域形成所述旋转 混合区。 上述隔壁还可以其它外形, 另外隔壁还可以设置在底座内腔的底面。
与现有技术相比, 本发明的优点在于: 首先蒸汽从蒸汽管接头喷出, 由于蒸汽管接 头出口是一个非常细小的孔, 在蒸汽通过小孔后会马上成伞状散开, 从而使蒸汽管接头 和壳体内的空间部分形成真空, 产生负压和虹吸效果, 在负压和虹吸的作用下, 牛奶和 空气会被吸入和蒸汽混合到一起,蒸汽、奶和空气混合后的混合物从壳体的引射口喷出, 在惯性及后续蒸汽推动下, 蒸汽、 奶和空气的混合物以高速度进入由隔壁形成的旋转混 合区, 在旋转混合区内旋转多圈, 在混合物旋转的过程中, 旋转混合区内蒸汽、 牛奶和 空气三者进一步得到了充分且均勾的混合, 从而形成细腻的奶泡, 没有乳化好的混合物 密度大, 离心力大, 会贴壁继续旋转再次混合乳化, 而乳化好的混合物密度小, 离心力 也小, 减速快, 先于没有乳化好的混合物流出出口, 最后乳化完成的带奶泡的牛奶在重 力的作用下, 会在速度降低后沿外壳内腔的底面经由出口流出。 附图说明

第二通道 17的侧部具有牛奶管接头 171,牛奶供给通道 13位于牛奶管接头 171内, 牛奶供给通道 13与奶气混合通道 21连通, 进气插头 6的侧壁上设有与进空气通道 15 相通的进气孔 61,进气孔 61通过进气插头 6与第二通道 17之间的间隙与牛奶供给通道 13连通, 即空气从进气插头 6内的进空气通道 14经由进气孔 61、进气插头 6与第二通 道 17之间的间隙、 下述辅助调节孔 63后进入牛奶供给通道 13内。
蒸汽管接头 5的头端外周面为外圆锥面, 第一通道 16的底部的内周面也为内圆锥 面,外圆锥面和内圆锥面之间形成锥形区 7,引射口 5和奶气混合通道 21通过该锥形区 7连通。
进气插头 6的后端具有辅助通道 62,辅助通道 62和进空气通道 14之间通过隔断壁 阻断, 辅助通道 62的侧壁上开有用以连通辅助通道 62和牛奶供给通道 13的辅助调节 孔 63。 第二通道 17的外端面上设有外凸的卡扣脚 172, 进气插头 6上供卡扣脚 172插 入的卡槽 64, 在卡扣脚 172插入卡槽 64并旋转一个角度的状态下, 卡扣脚 172卡扣在 卡槽 64后部, 进气插头 6的外周壁具有向外延伸的扳手部 65。 本牛奶发泡装置的工作原理及过程如下:
蒸汽从蒸汽管接头 5喷出, 由于蒸汽管接头 5出口是一个非常细小的孔, 在蒸汽通 过小孔后会马上成伞状散开, 从而使蒸汽管接头 5和壳体 1内的空间部分, 即在锥形区 7内形成真空, 产生负压和虹吸效果, 在负压和虹吸的作用下, 牛奶和空气会被吸入和 蒸汽混合到一起;
蒸汽、 奶和空气混合后的混合物从壳体 1的引射口 15喷出, 在惯性及后续蒸汽推 动下, 蒸汽、 奶和空气的混合物以高速度进入由隔壁 2分隔而形成的旋转混合区 3, 在 旋转混合区 3内旋转多圈;
在混合物旋转的过程中, 旋转混合区内蒸汽、 牛奶和空气三者进一步得到了充分且 均匀的混合, 从而形成细腻的奶泡, 没有乳化好的混合物密度大, 离心力大, 会贴隔壁 2继续旋转再次混合乳化, 而乳化好的混合物密度小, 离心力也小, 减速快, 先于没有 乳化好的混合物流出出口, 最后乳化完成的带奶泡的牛奶在重力的作用下, 会在速度降 低后沿外壳内腔的底面经由出口流出。 如图 5、 6所示, 为本发明的第二个实施例。
该实施例和第一个实施例的不同点在于: 隔壁 2呈螺旋状, 且螺旋状的隔壁 2的下 端面与底座 18的内底面之间具有供蒸汽、 奶和空气的混合物通过的间距 D, 该螺旋状 的隔壁 2围成的螺旋状区域形成所述旋转混合区 3。 如图 7〜10所示, 为本发明的第三个实施例。
该实施例和第一个实施例的不同点在于:壳体 1的顶部设有咖啡供给通道 20,咖啡 供给通道 20设置在上盖 19的底面上。该咖啡供给通道 20—直向下延伸并从出口 11的 中部穿出。
设置咖啡供给通道能使该发泡装置同时完成咖啡与奶泡的混合, 客户使用非常方 便, 只需要将杯子放在出口下方, 就可一键式完成一咖啡、 奶泡或咖啡加奶泡 (如拿铁、 卡布奇诺), 可任意选择, 传统的发泡装置如要制作卡布奇诺咖啡, 需要先通过蒸汽打 奶泡, 然后再煮咖啡, 其中打奶泡需要非常专业的人员才可以完成, 而且打好的奶泡还 要在倒在咖啡中, 过程非常繁琐;
此结构非常简单可以讲是傻瓜式的,不需要任何专业的打奶技术就可以得到非常高 品质的奶泡, 通过结构的优化, 使咖啡和奶泡实现了同一出口处流出, 解决使用者二次 操作的麻烦, 非常简便。 如图 11、 12所示, 为本发明的第四个实施例。
该实施例和第三个实施例的不同点在于:隔壁 2呈螺旋状,且螺旋状的隔壁 2的下 端面与底座 18的内底面之间具有供蒸汽、 奶和空气的混合物通过的间距 D, 该螺旋状 的隔壁 2围成的螺旋状区域形成所述旋转混合区 3。
