Description

一种吹气冷萃咖啡壶及其工作方法 技术领域
本发明涉及小家电技术领域，更具体地，涉及一种吹气冷萃咖啡壶及其工作方法。
背景技术
冷萃咖啡从萃取的过程当中一般是没有经过加热、是低温萃取而成的。而也因为冷萃咖啡需要低温且较长时间的萃取，所以在市面销售的冷萃咖啡价格一般都偏高。低温萃取也因此让冷萃咖啡具有独特的风味，同样的豆子不同的萃取方式可以产生完全不一样的味道，甚至因为低温萃取比较少萃取出咖啡的油脂，而可以保持较长的时间。
冷萃咖啡通常采用室温条件下或温度更低的水(例如，在20-22℃左右)浸泡咖啡粉并且通过过滤得到冷萃咖啡。但是，由于水温较低，咖啡粉中的物质很难被萃取出来，因此水和咖啡粉接触的时间必须很长。制作口感较好的冷萃咖啡可能需要12-48小时，时间成本非常高。因此如何缩短萃取时间，并使得咖啡粉中的物质较快地、充分的溶解在水中，从而高效地，快速地制作冷萃咖啡是急需解决的问题。
发明内容
本发明为克服上述现有技术所述的至少一种缺陷，提供一种吹气冷萃咖啡壶及其工作方法。本发明结构简单，使用方便，成本低廉、功能齐全、冷萃效果好，可高效地，快速地制作冷萃咖啡。
为解决上述技术问题，本发明采用的技术方案是：一种吹气冷萃咖啡壶，所述吹气冷萃咖啡壶包括：用于容纳咖啡粉和水的冲泡腔，所述冲泡腔具有冲泡腔开口，还包括用于供气至冲泡腔的供气装置，和用于引导来自供气装置的气体进入冲泡腔的导气部件，导气部件分别与所述供气装置和冲泡腔连接，所述供气装置通过导气部件与冲泡腔连接，使得所述供气装置能够供气至冲泡腔内混合形成的液体中。
上述的技术方案，可以实现制作冷萃咖啡过程中加速咖啡粉中的物质在水中的溶解中，实现快速、充分地萃取。当咖啡粉被放入冲泡腔并且供水装 置在供水至冲泡腔后，通过供气装置对水和咖啡粉混合形成的液体进行供气，由于气体会在液体中流动，因此带动液体流动和翻滚，使咖啡粉和水被充分搅拌，加速咖啡粉中的物质在水中的溶解，因此达到快速、充分萃取的效果。
在一个实施方式中，为了防止冲泡腔中的液体倒流至供气装置，污染供气装置甚至对其造成损害，导气部件被设置为至少部分高于冲泡腔内的液面。具体，导气部件被设置为至少部分高于或等于冲泡腔开口的高度。
在一个实施方式中，所述吹气冷萃咖啡壶还包括咖啡壶主体，所述冲泡腔、所述供气装置安装于咖啡壶主体上，所述冲泡腔开口设于冲泡腔顶部，所述供气装置通过导气部件与冲泡腔连接，用于供气至冲泡腔，以便在冲泡腔容纳有水和咖啡粉时，供气至水和咖啡粉混合形成的液体中。使用时，将水和咖啡粉通过冲泡腔开口供应至冲泡腔内，启动供气装置，则供气装置能够对水和咖啡粉混合形成的液体进行供气。
优选地，上述咖啡壶主体上还设有供水装置，其与冲泡腔连通，用于供水至冲泡腔。具体地，供水装置可以是设置咖啡壶主体上的水箱，所述供水装置包括位于冲泡腔上方的水箱，水箱底部设有出水口。所述出水口位于冲泡腔开口与出水口对应地的位置，所述水箱通过出水口向冲泡腔供水。
在一个实施方式中，所述吹气冷萃咖啡壶还包括能够覆盖在冲泡腔开口的上盖，所述冲泡腔开口设于冲泡腔顶部，所述上盖设有所述供气装置，所述供气装置通过导气部件与冲泡腔连接，使得所述供气装置能够供气至冲泡腔内的液体中。当上盖覆盖在冲泡腔开口上时，位于上盖的供气装置由于位置高于冲泡腔，可以避免液体倒流通过导气部件至供气装置。
在一个实施方式中，所述导气部件包括第一导气管，第一导气管具有第一导气管第一端口和第一导气管第二端口，所述第一导气管第一端口与供气装置连接，所述第二导气管第二端口插入冲泡腔内从而与冲泡腔连通，使得供气装置能够通过第一导气管供气至冲泡腔内的液体中。
作为一个实施方式中，所述导气部件包括第一导气管和第二导气管，第一导气管具有第一导气管第一端口和第一导气管第二端口，第二导气管具有第二导气管第一端口和第二导气管第二端口，所述供气装置与所述第一导气管第一端口连接，所述第一导气管第二端口与所述第二导气管第一端口连接， 所述第二导气管第二端口插入冲泡腔内与冲泡腔内连通，使得供气装置能够通过第一导气管和第二导气管供气至冲泡腔内的液体中。优选的，该第一导气管和第二导气管可分离地连接。由于第二导气管深入冲泡腔中与咖啡液体接触，会沾上咖啡液体，需要经常清洗。把第一导气管设置为与第二导气管可分离地连接，便于将第二导气管从第一导气管中分离出来单独清洗。
在一个实施方式中，所述冲泡腔设有透气网盖，所述透气网盖用于阻挡咖啡粉逸出，所述透气网盖可拆卸地安装地在冲泡腔开口对应的位置，所述导气部件被设置为能够贯穿透气网盖,使得所述导气部件的至少一部分能够插入冲泡腔内。透气网盖有利于用于将气泡或咖啡粉压制在冲泡腔内不会溢出，充分将上浮的咖啡粉溶解在水中。在对冲泡腔进行供气时，部分咖啡粉可能随气体飘向冲泡腔开口，其被透气网盖阻挡，滞留在透气网盖。所以，需要经常对透气网盖进行清洁。因此，透气网盖优选是可拆卸地冲泡腔上，便于将其拆下来清洁。
在一个实施方式中，所述透气网盖设有网盖开口，所述透气网盖上设有小盖与其转动连接，使得能够通过转动小盖打开或关闭所述网盖开口。在透气网盖上设置网盖开口及小盖能够方便用户通过网盖开口放置咖啡粉。这样，需要放置咖啡粉时，只需要转动小盖打开网盖开口，就能通过网盖开口将咖啡粉放入冲泡腔，而不需要将透气网盖整体从冲泡腔上取下来。当不再需要放入咖啡粉时，转动所述小盖关闭透气网盖开口，以阻止咖啡粉从冲泡腔中逸出。具体的，该透气网盖为圆形网盖，该透气网盖网盖包括盖框架和筛网。所述小盖为半圆形。该盖框架包括第一半圆部和第二半圆部，第一半圆部设有筛网，第二半圆部镂空形成透气网盖开口，第二半圆部覆盖有半圆形的小盖，该半圆形的小盖为与盖框架转动连接的翻盖。具体地，该网盖可以是具有透气孔的网状结构。
所述透气网盖设有所述第二导气管，所述第二导气管包括空腔和与空腔连通的管部，所述透气网盖内设有所述空腔，所述空腔与第一导气管第二端连通，所述透气网盖设有从冲泡腔盖向下延伸的所述管部，使得所述透气网盖覆盖在冲泡腔开口时，所述管部伸入所述冲泡腔内。
具体地，所述第二导气管穿过所述冲泡腔开口，所述第二导气管第二端 口位于冲泡腔内低于或等于冲泡腔中部的位置，以便第二导气管第二端口插入冲泡腔内的液体中。
在一个实施方式中，所述冲泡腔底部设有用于排放咖啡液的排放口，所述冲泡腔设有第一过滤件，所述第一过滤件被设置为使得咖啡液能够在通过排放口流出冲泡腔之前被所述第一过滤件过滤；所述排放口设有排放开关，所述排放开关用于打开或关闭所述排放口。虽然，在一个较为简单的实施方式中，可以不必设有咖啡液的排放口，咖啡液可以从冲泡腔开口倒出。但是，在冲泡腔底部设置排放口和排放开关能够更为方便的将咖啡液从排液口排出，用户只要打开排放开关，就能将咖啡液从排液口排出，使用更方便。具体地，上述第一过滤件可以是第一过滤网。在冲泡腔设置第一过滤件能够对咖啡液体进行过滤，以便去除咖啡液中的咖啡渣等杂质。可以理解的是，在一个较为简单的实施例中，并不一定需要在吹气冷萃咖啡壶中设置过滤件，因为在制作冷萃咖啡时，进行过滤的方式是因人而异的。用户可能会另外购买一次性滤纸进行过滤，在购买咖啡豆或者咖啡粉商家也可能会赠送滤纸，或者用户购买的滤杯也会配备滤纸。有些用户可能会觉得在咖啡壶中设置过滤件会增加清洗的工作，使用一次性滤纸之后不需要对滤纸清洗，可能会自备滤纸进行过滤。
优选地，所述第一过滤件可拆卸地安装在冲泡腔内，并将冲泡腔分隔为位于冲泡腔上部的溶解室和位于冲泡腔下部的过滤室，所述第一过滤件和所述排放口之间还设有第二过滤件。第一过滤件可拆卸地冲泡腔内有利于将第一过滤件拆卸下来单独清洗。第二过滤件可以对已被第一过滤件过滤的咖啡液进行再次过滤，进一步去除咖啡液中的杂质。所述第二过滤件优选用可拆卸地安装在第一过滤件和排放口之间。另外，在用户希望自备其他过滤件的情况下，比如用户自备一次性滤纸时，可以在将第一过滤件拆卸下来再使用吹气冷萃咖啡壶，在使用吹气冷萃咖啡壶制作冷却咖啡之后，用户再另外使用其自备的滤纸进行过滤。
优选地，所述过滤室下方还设有放置用于盛放咖啡的咖啡杯，所述咖啡杯上设有用于过滤咖啡的第三过滤件，第三过滤件与所述咖啡杯可分离的连接。比起直接享用从排液口排出咖啡，用第三过滤件第三次进行过滤可以进 一步去除咖啡液中的杂质，进一步提高咖啡的口感。第三过滤件被设置能够与所述咖啡杯分离以便清洗。
优选地，所述咖啡壶还可以包括用于驱动排放开关的驱动装置，所述驱动装置设置咖啡壶主体上。所述驱动装置可以包括驱动部件和与驱动部件向连接的电机，或者所述驱动装置可以包括驱动部件和与驱动部件向连接的电磁阀。具体的，所述驱动部件可以是与排放开关可分离地连接或者固定连接的驱动杆。
一种应用上述的吹气冷萃咖啡壶的工作方法，包括以下步骤：
S1：将咖啡粉放入冲泡腔，供水至冲泡腔，使得水与咖啡粉混合；
S2：供气装置通过导气部件将气体提供至冲泡腔内的水和咖啡粉混合形成的液体中，使得气体流动搅拌咖啡粉从而咖啡粉在液体翻滚溶解；
S3：供气装置停止工作，咖啡在冲泡腔进行过滤，咖啡在过滤之后从冲泡腔中排出。
与现有技术相比，本发明的有益效果：
本发明的技术方案，可以实现快速地对制作冷萃咖啡。当咖啡粉被放入冲泡腔并且供水装置在供水至冲泡腔后，通过供气装置对水和咖啡粉混合形成的液体进行供气，由于气体会在液体中流动，因此带动液体流动和翻滚，使咖啡粉和水被充分搅拌，加速咖啡粉中的物质在水中的溶解，因此达到快速、充分萃取的效果。

实施例4
如图12所示，本实施例与实施例3基本相同，不同之处仅在于，第二导气管的管壁设有出气孔0134，出气孔0134位于透气网盖002和第一过滤件003之间，以便部分气体可以通过出气孔0134进入溶解室内；同时，由于第一过滤件003是第一过滤网003，因此还可以通过第一过滤网003的网孔出气到冲泡腔6，气泵工作时，气体通过第二导气管进入过滤室6002产生压力将过滤室6002内的至少一部分水压出过滤室6002，并且将气体打入冲泡腔6致使咖啡粉与水一起翻滚溶解。因此，本实施例中，气体通过出气孔0134或第一过滤网的网孔进入。在其他实施例中，出气孔0134可以在第一过滤件003上。
