Description

Automatic drip type coffee machine

Technical Field

The present invention relates to a drip coffee maker, and more particularly, to an automatic drip coffee maker.

The present invention is derived from a study carried out by a Noble tree of a limited stock company as a part of a small and medium-sized enterprise and a new-creation enterprise (new-creation enterprise growth technology development business). [ study period: 31/2020-2021, study management professional: technical information of small and medium enterprises is developed, and the name of a research topic is: development of nozzle independent intelligent (intelligent) automatic drip (3 ports), topic identification number: s2856246]

Background

Drip coffee (drip coffee) is a coffee obtained by pouring warm water (or boiling water) into coffee powder obtained by finely pulverizing raw coffee beans and filtering the coffee powder. The drip type coffee has a disadvantage in that it is difficult to provide service in a coffee house (coffee shop) or a cafe (cafe) due to insufficient manpower and poor strength between people because of inconvenience caused by a person who needs to pour warm water into a drip head including a filter net containing coffee powder over time. In order to improve this hand-brewed coffee making method, an automatic drip coffee maker is proposed.

In general cases of extracting drip coffee, the temperature of warm water to be extracted differs depending on the degree of roasting or pulverizing of the coffee, the type of coffee, and the density, and the temperature of warm water in a pot gradually cools during the extraction, so that the temperature of warm water gradually decreases in each extraction step. Therefore, when drip coffee is extracted, fine adjustment of the temperature of warm water according to the extraction step or coffee conditions affects the extraction quality.

However, in the automatic drip coffee maker of the related art, since the boiler is constituted as a single one, the temperature cannot be adjusted according to the condition of each coffee, and thus it is difficult to extract drip coffee of excellent quality. Also, the related art automatic drip type coffee maker cannot precisely control the temperature or flow rate of the warm water supplied to the dripper, and it is also difficult to precisely control the drip pattern of the warm water supplied to the dripper, and thus, quality of drip type coffee, such as aroma, etc., may be poor.
