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 coffee maker that has been steeped in water or hot water, shake it until it gets cold, and then transfer it to a glass, or use it as a drip-type iced coffee maker as shown in Figure 1a. 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 made by placing medium-fine ground coffee in the upper cup 1 and ice pieces in the middle cup 3, and then pouring hot water into the upper cup 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 such drawbacks, and its characteristics include the formation of a large number of heat absorption (heat dissipation) fins on the outer peripheral surface of the hollow body between the top and bottom plates of the body, A regenerated cooling body containing a cold storage heat agent inside the housing is housed in an intermediate cup interposed between the upper cup and the lower cup, and the coffee liquid extracted with hot water and flowing down through the fins is cooled. The present invention provides a drip type iced coffee maker characterized by the following features.

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

Figure 2 is an exploded perspective view of the drip-type iced coffee maker of this invention, where 11 is an upper cup with a number of pores 13 in the bottom plate 12, and 17 is an upper plate as shown in Figures 4a and l). For example, it is fixed integrally with the upper and lower plates in a truncated conical adult body 20 sealed by a lower plate 18 and a lower plate 19, and a fin 20A is formed by a circumferential groove 21 on the outer peripheral surface of the adult body. a regenerated cooling body containing a cold storage heat agent 23 made of a refrigerant that is easily available and relatively economical, such as ethylene glycol or carboxymethyl cellulose; 24 is a funnel-shaped intermediate cup into which the regenerated cooling body is placed; Reference numeral 25 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.

In addition, although 16 is a cylindrical hollow part, a hollow part is not necessarily necessary.

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 4), the lower cup 2 is
Insert the intermediate cup 24 using the elastic member 28 of No. 5,
The regenerated cooling body 17 that has been sufficiently cooled in the freezer compartment of the refrigerator is placed in this intermediate cup, and the upper cup 11 is placed on top of this intermediate cup 24 via the flange 14. A filter paper 29 is placed inside this upper cup, and the After roasting, add medium-finely ground coffee beans a to complete the drip preparation.

Next, boiled hot water is poured little by little into the upper cup 11 and extracted through the filter paper 29. The coffee liquid is evenly dispersed on the upper plate 18 and passes through the through holes 15 of the regenerated cooling body 17 in the middle cup 24. Slowly poured heat absorbing fin 2
While flowing down through the OA and 20A, it is cooled and accumulates in the lower cup 25 from the intermediate cup 24.

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.

Improvement cup 11. Upper and lower plates 18 of the regenerative cooling body 17.
19 The housing 20 and the intermediate cup 24 are made of a metal material that is resistant to thermal stress so that they will not be easily damaged.
Preferably, it is made of a material such as stainless steel.

As mentioned above, this invention allows for regenerative cooling by forming a large number of heat absorption (heat dissipation) fins on the outer peripheral surface of the adult body between the upper and lower face plates of the adult body of Doukou, and by putting a cold storage heat agent inside the housing. The body is housed in an intermediate cup interposed between an upper cup and a lower cup, and the coffee liquid extracted with hot water and flowing down through the fins is cooled, so that the extracted coffee can be cooled 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 and commercial purposes.
