Description

Portable Coffee Maker {POTABLE COFFEE MAKER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable coffee maker designed to be portable and portable, and more particularly, to a portable coffee maker that is miniaturized by using a simple structure and can be easily carried on the fly.

Generally, coffee is a beverage made by roasting coffee bean produced from coffee tree for a certain period of time, crushing beans finely, and extracting the ingredients using water.

These coffees have become popular drinks in places where people gather in recent years.

It is a trend that people like to make coffee directly with a machine such as a French press or a hand drip that mixes coffee beans and hot water and then filters them by a filter. These coffee makers have the advantage that they can make coffee easily and cheaply.

More specifically, the drip coffee is a coffee which is roasted and puts the coffee beans in a manure apparatus and pours water thereon, and a drip brew refers to a method of making coffee in this way. Since the filter is also called a filter, drip coffee is called filter coffee in other words.

The coffee maker allows water to escape through the coffee, using only gravity. At this time, water passes through the coffee layer and absorbs the oil component and essence of coffee. Then the water passes through the bottom of the filter, but the coffee powder does not pass through the filter, and only the liquid component that has passed through the filter falls into the container of the carafe or coffee pot or the like and is contained inside.

One of the advantages of the paper filter is that the filter can be a paper filter, a metal filter, and the like, and paper filters are widely used worldwide, and the coffee can be extracted and then discarded with coffee powder directly. Because there is no need to clean it. In addition, drip coffee made with paper filters is generally relatively clean, light, and low in sediment, but since the oil and essence of the coffee may remain in the paper filter, It may be somewhat lacking.

Also, the metal filter is made of a thin sheet of metal with holes, allowing the coffee to pass while not allowing the coffee powder to pass through. Such metal filters are very useful in that there is no need to purchase filters separately.

In addition, there are permanent plastic filters used in many coffee machines. This filter is a plastic filter in the form of a fine body, which is troublesome to manage, but it is economical and also has an advantage of being environmentally friendly.

As described above, the manufacturing method of drip coffee is the most common coffee making method which can be easily made by using a coffee maker. In addition to an automatic coffee maker, a manual drip-brewing machine is sold in the market. Manual devices are preferred because they can adjust the parameters to suit their preferences.

In addition, Drippie makers that make only one cup of small portable are also available. When a pedestal that supports the filter is placed on the cup and hot water is poured on it, the hot water immediately drips into the cup. This type of drip coffee is called hand drip or hand drip coffee, which is made by pouring hot water directly by hand. Dripper is called a dripper, and a kettle that holds downed coffee is called a server.

In the drip coffee and tea automatic machine of Korean Patent No. 10-0897948, the driving means includes a first conveying shaft for horizontally conveying the droplet nozzle, a first conveying shaft for horizontally conveying the droplet nozzle, And a direction switching unit for converting the rotational motion of the first and second driving motors into a linear motion. The first driving motor includes a driving motor, a second conveying shaft disposed perpendicular to the first conveying shaft, a second driving motor of the second conveying shaft, And a direction changing unit which is constituted by a cylindrical cam formed with a diagonal groove and mounted on the drive shaft of the motor and a cam shaft projecting from the feed shaft and moving along the groove or formed of a rack and a pinion, In a circular or spiral manner.

However, the conventional drip coffee maker as described above is bulky to carry, and there is a problem in that drip coffee can not be used immediately without preparing a separate cup.

In addition, since the conventional portable coffee maker simply puts the upper cup on the lower cup, when the upper cup is placed on the lower cup, water is poured into the upper cup, or when the upper cup and the lower cup are moved, There is a problem that the upper cup is likely to fall and the transportation and storage thereof becomes difficult.

Korean Registered Patent No. 10-1428669 (Announced 2014.08.11) Korean Patent Publication No. 10-0675750 (published on January 30, 2007) Korean Registered Utility Model No. 20-0278592 (published Jun. 20, 2002)
