Coffee brewer water supply device

This creation is about a coffee brewing device, especially a coffee brewing device that can precisely control the quantitative water supply technician.

According to the brewing tools for brewing coffee, there are mainly hand-washing or machine brewing. The factors that need to be considered in terms of brewing coffee include coffee volume, brewing temperature and water volume. Can brew a certain coffee flavor, in addition to the above factors that can be prepared in advance, there is also a brewing program to cooperate, these brewing factors that have to pay attention to each time, if it can be handed over to the machine brewing machine Providing, can be said to be a considerable convenience, which is also an improvement goal for coffee machine operators.

The general coffee brewing machine is provided with coffee powder installation and water heating function. The use of the top part is a brewing unit. In some brewing machines with continuous multi-cup brewing ability, it can be found in multiple brewing. Every time the actual cup volume of each cup is the same as the original cup size, there is nearly 10% cup error between successive cups. The reason for the drop is mainly determined by the amount of water supplied in the brewing. The programmed brewing machine, the amount of water supplied for brewing is controlled by the length of time, and only the water supply is not calculated. Therefore, when the water supply is insufficient, it can not be compensated immediately, so that each brewing is about 250CC. The amount of cups is inconsistent or insufficient. The obvious difference is that the components of the electrical matching mechanism are cost considerations, and the accuracy requirements are not High, on the other hand, the problem of machine maintenance and life-use, which affects the error between the actual water supply and the standard set water supply. These error problems have become the main research purpose of this case.
