Description

起泡装置
技术领域
本公开总体上涉及用于制备牛奶的机构，该牛奶用于基于浓缩咖啡或可可的饮品，诸如卡布奇诺、拿铁咖啡和摩卡。
背景技术
在咖啡店中通常会看到为卡布奇诺制备优质丝滑质感的牛奶，其允许咖啡师在饮品上产生已知为“拿铁艺术”的优雅图案。这样的商店使用包含多台水锅炉的大型商用浓缩咖啡机，其中一台水锅炉专门用于产生滚烫和高压的蒸汽。该蒸汽在高速下被推动通过蒸汽棒以加热牛奶并产生泡沫。经验丰富的咖啡师可以进一步破裂泡沫中的气泡以产生甚至更小的气泡，其可被称为微泡沫。微泡沫的牛奶在倾倒时会与浓缩咖啡混合，并且为最终的饮品增添良好感觉的甜味。
虽然家庭咖啡师可能使用具有蒸汽锅炉和棒的浓缩咖啡机来产生泡沫，但是产生适合于产生拿铁艺术的丝滑微泡沫质感牛奶却是另一回事。典型的家用机器不如在咖啡店中发现的商用机器那么坚固。此外，许多小型家用浓缩咖啡机根本不包括第二个锅炉或蒸汽棒，并且仅生产浓缩咖啡，从而使用户无法产生任何类型的微泡沫牛奶。为了弥补这些不足，已经设计了供家庭使用的起泡装置。这样的装置通常采用小搅拌器来产生普通大小的气泡，从而导致牛奶几乎立即分离，并且在顶部具有浓厚的泡沫质地，而在底部具有牛奶。当倾倒时，牛奶将首先流出，最后是一团泡沫。该泡沫团无法与浓缩咖啡饮品很好地混合，产生顶部有泡沫牛奶且底部有浓缩咖啡的口味分离，并且不容许令人满意的拿铁艺术。
因此，解决这些和其他问题的起泡装置是所期望的。
实用新型内容
所公开主题的一个示例性实施例是一种起泡装置，其优选地具有手柄、连接至手柄的可旋转轴、能够通过可旋转轴的叶轮、以及围绕叶轮与手柄相对地设置的筛网。起泡装置可进一步包括围绕叶轮和筛网设置的保持器。筛网在形状上优选地是环形的。轴可以与叶轮成一体，但是优选地经由螺纹布置来联接。
在另一个示例性实施例中，起泡装置包括可旋转轴、能够通过可旋转轴的叶轮、以及在由叶轮推动的流体流的下游围绕叶轮的底部设置的筛网。该起泡装置还可以具有联接至可旋转轴的手柄。保持器可以围绕叶轮和筛网设置。
在手柄布置的替代方案中，起泡装置可以包括具有底壁的罐，其中可旋转轴从罐的底壁向上延伸。通过该构造，叶轮优选地包括构造成接收可旋转轴的通道。而且，起泡装置可以包括壳体，其具有加热器和从壳体向上延伸的凸块。轴在其底部具有开口，其中轴的开口构造成接收凸块。保持器优选地围绕叶轮和筛网设置，其中筛网具有构造成接收叶轮的孔。
所公开主题的另一个示例性实施例是一种起泡的方法，其包括使用起泡装置在牛奶中产生涡流，其中起泡装置包括可旋转轴、能够通过轴旋转的叶轮、以及在由叶轮推动的流体流的下游围绕叶轮的底部设置的筛网。然后，通过将叶轮从中心移开或者通过减慢叶轮的旋转来停止涡流，其中牛奶被搅动直至形成微泡沫。可旋转轴可以联接至手柄。在替代方案中，起泡装置可以包括罐，其中可旋转轴围绕罐的底壁设置。罐围绕壳体布置，该壳体具有加热器和从壳体延伸的凸块，其中可旋转轴构造成接收凸块。保持器可以围绕叶轮和筛网设置。

具体实施方式
下面呈现了实践本公开的一般的非限制性概述。该概述总括了本公开的实施例的示例性实践，从而为变型和/或替代和/或发散的实施例提供了建设性的基础，其中一些随后描述。
图1-4示出了本文公开的新型起泡装置100的一个这样的示例性实施例。如图1中所示，装置100优选地包括联接至可旋转轴104的手柄102。轴104又联接至具有叶片108的叶轮106。叶片108可以为根据期望产生的推力量而改变的尺寸和形状，如下面所论述的。
如图2中最佳所见，筛网112围绕叶轮106与轴104相对地设置。筛网112内的孔的大小也可以为根据用户期望最终气泡大小在所得的微泡沫中有多大或多小而改变的尺寸和形状。筛网112可以例如经由焊接、共注塑或不太持久的某种布置而联接至叶轮106。然而优选地，筛网112借助保持器110而围绕叶轮106设置。
图2示出了保持器110在形状上可以是环形的，其中筛网112和叶轮106都被保持器110约束并保持在适当的位置，以增加整个装置100的支撑和刚性。
图2还示出了轴104优选地经由螺纹和凹槽布置而联接至叶轮106。特别地，轴104可具有螺纹116，其构造成与切入叶轮106的通道中的凹槽120相接合。
返回图1，起泡装置100优选地在手柄102中包括开关114。开关114与电路和诸如一个或多个电池的电源15电连通。开关114容许装置100通电或断电，并且还优选地容许轴104以变化的速度旋转。
在操作中，通过将热的或冷的牛奶放入罐122或容器中，并将叶轮106和筛网112浸入中心附近的牛奶中，从而操作装置100，如由图3A所示出的。然后，用户可以拨动开关114以旋转轴104。这样做将导致叶轮106和筛网112在牛奶内部快速地旋转，以产生涡流。涡流又将环境空气与牛奶混合，以形成气泡和泡沫。当装置100被进一步偏心地移动时(如图3B中所见)，涡旋停止，并且叶轮106变得完全被浸没。不再接触环境空气且不再形成新的泡沫气泡，叶轮106现在仅仅搅动牛奶并将泡沫向下拉到它被推动通过叶轮106和筛网112的位置。泡沫气泡因此在它们反复地被迫通过筛网112时破裂成微小的气泡124，如图4中最佳所见。结果是丝般光滑的微泡沫牛奶，用于倾倒在浓缩咖啡或类似物上方并产生拿铁艺术，如果需要的话。
因此，正是筛网112设置在叶轮106下方(即流的下游)的特定构造产生了微泡沫，而不是蒸汽或搅拌器的使用。此外，值得注意的是，这种构造是反直觉的，和/或与可能被认为是常规过滤器和叶轮布置的构造相反。换而言之，筛网或过滤器将典型地设置在叶轮上方，即流的上游，以过滤掉不想要的材料以免进入叶轮中并因此不可挽回地损害它。然而，利用所公开的实施例，筛网112在流的下游——不是出于过滤掉任何不期望材料的目的——而是为了破裂流中的气泡以产生期望的微泡沫。
图5A-7C示出了所公开主题的另一个实施例。如其中所见，起泡装置200优选地包括围绕壳体206设置的罐202。罐202包括围绕罐202的底壁设置的可旋转轴204，如图5B中最佳所见。轴204包括通道，其构造成接收围绕壳体206的顶壁设置的可旋转凸块210。
装置200还包括具有叶片216的叶轮214，叶片216根据用户喜好而改变尺寸和形状，如以上在图1-4的情境中所论述的。叶轮214构造成接合可旋转轴204，如图6A-6B中示出的。图7A示出了示例性接合的分解图，该示例性接合是通过切入叶轮214中以接收可旋转轴204的通道218而获得的。代替该构造，装置200可以使用磁性旋转布置来转动叶轮214。
图7A还显示以如上所论述的下游布置围绕叶轮214设置的筛网222的使用。换而言之，叶轮214能够通过轴204而旋转，其中叶轮214具有顶部和相对的底部。叶轮214构造成使流体从叶轮214的顶部移动到底部，其中筛网222围绕叶轮214的底部设置。
筛网222可以永久地附接到叶轮214，或者是可移除的，如以上所论述的。此外，可选的保持器210可以部分地包封叶轮214和筛网222，后者优选地在其中具有位于中心的切口，以接收可旋转的叶轮214的底部部分，如图7A-7C中最佳所见。
再次参照图5A，壳体206优选地包括加热器208，用于加热罐202中的牛奶。开关212围绕壳体206设置。开关212与诸如一个或多个电池的电源电连通。开关212可以由用户接合以启动装置200，从而致使加热器208加热并使轴204旋转，以旋转叶轮214。用户可以使用开关212来改变叶轮的速度，和因此牛奶从罐202的顶部流动通过叶片216且然后通过流下游的筛网222的速度。这样做容许用户产生涡流并给牛奶充气，或者搅动并产生微泡沫。
图8A-8B示出了所公开主题的另一个实施例。在此，起泡装置300可以包括罐302，该罐302包含围绕罐302的底部设置的防水可旋转轴304。与图5A-7C中所示出的类似的叶轮308、筛网和保持器310布置可以从罐302内部连接至该轴304。这样做将叶轮308和筛网构件定位在罐302的底部附近，并且优选地稍微偏心。装置300还优选地包括壳体306，其具有带电动旋转凸块的热板。当罐302被放置在热板上时，凸块定位成与轴304联接。当启动时，热板加热罐302以温热牛奶，并且旋转凸块且混合牛奶。充分地加速叶轮308和筛网将在牛奶中产生涡流，而减速将停止涡流，并且搅动牛奶以产生期望的微泡沫，如上文所论述的。
尽管已经描述了某些实施例，但是这些实施例仅仅以示例的方式呈现，并不旨在限制本实用新型的范围。实际上，本文描述的新型起泡装置和相应的方法可以以多种其他的形式实施。而且，在不脱离本实用新型的精神的情况下，可以对所公开元素的形式做出各种省略、替换和改变。所附的权利要求书及其等同方案旨在覆盖落入本实用新型的范围和精神内的此类形式或者修改。
