背景技术Background Art
咖啡是人类社会流行范围最广泛的饮料之一，随着人们生活质量的提升，对咖啡品质的要求也日渐提高。Coffee is one of the most popular beverages in human society. As people's quality of life improves, their requirements for coffee quality are also increasing.
目前市面上大部分的咖啡机，冲泡咖啡过程中主要存在两个问题，第一个问题是：咖啡机没有研磨功能，大多采用已经研磨好的咖啡粉进行冲泡，但咖啡的香气物质在咖啡豆磨成粉后挥发极快，因此研磨好的咖啡粉并不能保证咖啡的品质和口感；第二个问题是：要保证咖啡的口感与品质，注水冲泡过程非常重要，现在市场上大部分咖啡机采用滴滤式注水，注水口出水不稳定，注水时容易破坏粉层状态，从而破坏咖啡萃取效率，影响咖啡的口感。Most of the coffee machines on the market currently have two main problems in the coffee brewing process. The first problem is that the coffee machines do not have a grinding function, and most of them use pre-ground coffee powder for brewing. However, the aroma substances in coffee evaporate very quickly after the coffee beans are ground into powder. Therefore, the ground coffee powder cannot guarantee the quality and taste of the coffee; the second problem is that to ensure the taste and quality of coffee, the water injection and brewing process is very important. Most of the coffee machines on the market now use drip water injection, and the water output from the water injection port is unstable. When injecting water, it is easy to destroy the powder layer, thereby destroying the coffee extraction efficiency and affecting the taste of the coffee.
为解决上述问题，本发明采用齿轮齿圈配合、内外圆盘偏心配合的注水技术，内圆盘可通过人为调整的方式相对外圆盘旋转，以实现一定范围内不同轨迹的注水，机械结构较小，轨迹可控，解决了咖啡粉的吃水情况和冲泡过程中构建流水通道的现象，较好的保持了咖啡的质量和特色，提高了咖啡出品的稳定性；采用锥刀盘与外刀盘相配合的研磨技术，通过旋转调节螺母改变研磨空间大小以调节咖啡豆研磨的粗细度，实现不同口感咖啡的制作，且调节螺母可以从中心轴向下旋出，方便中心杆与锥刀盘拆卸，便于清洗。To solve the above problems, the present invention adopts a water injection technology in which a gear ring cooperates and an eccentric inner and outer disc cooperates. The inner disc can be rotated relative to the outer disc by artificial adjustment to achieve water injection with different trajectories within a certain range. The mechanical structure is small and the trajectory is controllable. The water intake of coffee powder and the phenomenon of building a water flow channel during the brewing process are solved, the quality and characteristics of the coffee are better maintained, and the stability of the coffee products is improved. The grinding technology in which a conical blade disc and an outer blade disc cooperate is adopted. The size of the grinding space is changed by rotating the adjusting nut to adjust the coarseness of the grinding of coffee beans, thereby achieving the production of coffee with different tastes. The adjusting nut can be unscrewed downward from the center axis, which is convenient for disassembly of the center rod and the conical blade disc and easy for cleaning.

考虑到研磨不同颗粒大小与不同烘焙深浅的咖啡豆所需转圈数和所用时间不同，上述研磨步进电机25的转速为60r/min，研磨外齿圈28齿数56，研磨电机齿轮24齿数20。Taking into account the different numbers of revolutions and times required for grinding coffee beans of different particle sizes and different roasting depths, the rotation speed of the grinding stepper motor 25 is 60 r/min, the number of teeth of the grinding outer gear ring 28 is 56, and the number of teeth of the grinding motor gear 24 is 20.
考虑到注水过程的稳定、均匀，上述注水步进电机18转速为20r/min。Considering the stability and uniformity of the water injection process, the rotation speed of the water injection stepping motor 18 is 20r/min.
上述一种具有新型注水、研磨功能的全自动咖啡机外观尺寸长×宽×高为360mm×300mm×510mm，水壶8容积2L，一次冲泡咖啡量为400ml。The above-mentioned fully automatic coffee machine with new water injection and grinding functions has an appearance size of 360mm×300mm×510mm in length×width×height, the kettle 8 has a capacity of 2L, and the amount of coffee brewed at one time is 400ml.
使用本发明时，首先在触摸屏50上设置液体加热的温度和研磨的时间，然后根据所要求的咖啡豆的研磨粗细程度，旋转调整螺母调节研磨空间；设置完成后，按下启动按钮45和自动按钮48，蓄水装置中PTC陶瓷加热片开始对液体进行加热，运输传送装置中步进电机正转，螺杆正转，右限位传感器检测到滤杯到达右限位后，咖啡豆从豆仓装置落入研磨装置中，咖啡豆从传动盖上方落入锥刀盘，研磨步进电机通过研磨电机齿轮与研磨外齿圈配合带动传动盖旋转，传动盖通过中心轴将动力传递到锥刀盘，带动锥刀盘旋转，锥刀盘与外刀盘产生相对运动，研磨咖啡豆，咖啡粉落入滤杯中；研磨时间到，步进电机反转，螺杆反转，左限位传感器检测到滤杯到达左限位且蓄水装置中的液体温度达到设定温度时，注水步进电机18开始工作，注水电机齿轮17带动注水外齿圈22、注水外圆盘21与注水内圆盘19转动，注水外圆盘21与注水内圆盘19偏心配合，从入水口20流入注水内圆盘19的液体通过出水口23按一定轨迹流入滤杯43中冲泡咖啡粉，冲泡好的咖啡成品通过滤杯流入放置在底板上的杯子里，底板上的保温盘，实现对杯体保温，避免咖啡液降温影响口感，按下停止按钮结束全部工作，按下启动按钮和手动按钮，实现单步操作，每按一次手动按钮49，完成一项咖啡冲泡功能。When using the present invention, first set the temperature of liquid heating and the grinding time on the touch screen 50, and then rotate the adjustment nut to adjust the grinding space according to the required grinding coarseness of the coffee beans; after the setting is completed, press the start button 45 and the automatic button 48, the PTC ceramic heating plate in the water storage device starts to heat the liquid, the stepper motor in the transport transmission device rotates forward, the screw rotates forward, and the right limit sensor detects that the filter cup reaches the right limit, and the coffee beans fall from the bean bin device into the grinding device, and the coffee beans fall from the top of the transmission cover into the conical cutter disc, the grinding stepper motor drives the transmission cover to rotate through the grinding motor gear and the grinding outer gear ring, the transmission cover transmits power to the conical cutter disc through the central shaft, drives the conical cutter disc to rotate, the conical cutter disc and the outer cutter disc produce relative motion, grind the coffee beans, and the coffee powder falls into the filter cup; when the grinding time is up , the stepper motor reverses, the screw reverses, and the left limit sensor detects that the filter cup reaches the left limit and the liquid temperature in the water storage device reaches the set temperature, the water injection stepper motor 18 starts to work, and the water injection motor gear 17 drives the water injection outer gear ring 22, the water injection outer disc 21 and the water injection inner disc 19 to rotate. The water injection outer disc 21 and the water injection inner disc 19 are eccentrically matched, and the liquid flowing into the water injection inner disc 19 from the water inlet 20 flows into the filter cup 43 through the water outlet 23 according to a certain trajectory to brew coffee powder. The brewed coffee product flows into the cup placed on the bottom plate through the filter cup. The insulation plate on the bottom plate keeps the cup body warm to prevent the coffee liquid from cooling down and affecting the taste. Press the stop button to end all work, press the start button and the manual button to realize single-step operation, and each time the manual button 49 is pressed, a coffee brewing function is completed.
