Description

[Detailed Description of the Invention] This invention relates to a coffee maker, and more specifically to a drip type iced coffee maker.

Iced coffee and cafe frappe are summer drinks, but how to make iced coffee is to put ice cubes in a glass and pour coffee infused with water or hot water to make it cold, or to make ice in a shaker. You can use a container for brewing coffee with coffee beans and water or hot water, shaking it until it gets cold, and then transferring it to a glass, or a drip-type iced coffee maker as shown in Figure 1a, in which roasted coffee beans can be poured into a container. It consists of an upper cup 1 for storing finely ground food, an upper filter 2 for attaching a filter paper that overlaps with the cup, an intermediate cup 3 for storing ice chips, and a lower filter 4 that overlaps the intermediate cup and lower cup 5. As shown in Figure 1, this iced coffee maker is constructed by placing medium-finely ground coffee in the upper cup 1 and ice pieces in the middle cup 3, and pouring hot water into the upper cup 1, as shown in Figure 1. There is a system in which the extracted coffee is cooled by ice chips in the middle cup 3 and then stored in the lower cup 5.

However, these methods have the disadvantage that when the brewed coffee is cooled, the ice pieces melt, resulting in watery coffee.

The purpose of this invention is to eliminate these drawbacks, and its feature is that a cold heat storage agent is placed inside a rod-shaped hollow body and sealed to create a large number of regenerated cooling bodies. To provide a drip type iced coffee maker characterized in that coffee is stored in an intermediate cup interposed between an upper cup and a lower cup, and the coffee liquid flowing down is cooled by extraction with hot water.

An embodiment of this invention shown in the drawings will be described in detail below.

FIG. 2 is an exploded perspective view of the drip-type iced coffee maker of this invention, and numeral 11 is an upper cup having a bottom plate 12 with a number of pores 13.

Reference numeral 17 denotes a regenerative cooling body according to this invention, and this regenerative cooling body has an upper plate 18 and a lower plate 19 as shown in FIG.
As a result of accommodating or bundling a large number of rod-shaped hollow bodies 20 sealed with
A cold heat storage agent 23 made of a synthetic paste material such as ethylene glycol or carboxyl methyl cellulose, which is easily available and relatively economical, is placed inside the container.

24 is a funnel-shaped intermediate cup into which the regenerated cooling body is placed;
Reference numeral 5 designates a lower cup having a spout 26 and an elastic member 28 attached to the inner periphery of the bottom portion 27 for inserting the intermediate cap.

The drip-type iced coffee maker of this invention is constructed with the above-mentioned components, and in use, as shown in Figures 3 and 4 a and 1), the lower cup 25 is
The intermediate cup 24 is inserted using the elastic member 28, and the regenerated cooling body 17, which has been sufficiently cooled in the freezer compartment of the refrigerator, is inserted into the intermediate cup, and the upper cup 11 is placed on top of the intermediate cup 24. A filter paper 29 is placed in this upper cup, and roasted and medium-finely ground coffee beans a are placed therein to complete the drip preparation.

Next, boiled white water is poured little by little into the upper cup 11, passed through the filter paper 29, and the extracted coffee liquid is evenly dispersed and poured onto the regenerated cooling body 17 in the middle cup 24 through 16. While passing through the gap 16 of the rod-shaped hollow body 20, it is cooled and the lower cup 2 is cooled from the intermediate cup 24.
It accumulates within 5.

The coffee collected in the lower cup 24 is poured into a pre-chilled glass or the like, and a sugar solution is added according to taste.

You can make iced coffee by injecting chilled milk.

The regenerated cooling body 17 which has lost its cooling capacity can be reused by being cooled again in the freezer, and if a plurality of these regenerated cooling bodies are prepared, a large amount of iced coffee can be made continuously.

Furthermore, upper cup 11. Upper and lower plates 18 of the regenerative cooling body 17.
19. Rod-shaped hollow body 20. If the intermediate cup 24 is made of a metal material that is resistant to thermal stress, it will not be easily damaged and will be placed above the regenerative cooling body 17.
The lower plates 18, 19 and the rod-shaped hollow body 20 are preferably made of materials with good thermal conductivity, such as aluminum or stainless steel, and are shaped like WXr.

As described above, according to this invention, a cold heat storage agent is placed inside a rod-shaped hollow body and sealed to create a large number of regenerated cooling bodies, and these many regenerated cooling bodies are placed in an intermediate cup interposed between an upper cup and a lower cup. By storing the coffee in a cup and cooling it by extracting it with hot water and cooling the flowing coffee liquid, it is possible to cool the extracted coffee without diluting it.
The regenerated cooling body can be reused by simply freezing it, and has the advantage that it can be used for general household use as well as commercial use.
