Description

[Detailed explanation of the idea] Industrial applications The present invention relates to an improvement in a coffee brewing device.

Conventional technology: coffee siphon, disposable filter for one person, Utility Model Publication No. 50-24371
A liquid receiver, a pouring tube, as proposed in the publication,
A dispensing device consisting of a sprinkling cylinder and a pouring device stacked one after the other, a water tank and a filter cylinder suspended in sequence in a transparent box frame as proposed in Publication No. 50-31823, There are known types of extractors that include a water tap type extraction device in which a pot is placed below a filter cylinder.

Problems to be Solved by the Invention When using a coffee siphon or a drip-type brewing device, a rich aromatic coffee liquid that is not oxidized can be obtained, but the extraction time becomes longer.

When using a disposable filter and dispensing device, pouring hot water causes the coffee oil in the coffee grounds to escape, reducing the aroma and oxidizing the coffee grounds, resulting in a decrease in tastes such as bitterness and sourness.

In addition, in order to prevent the loss of the aroma of coffee liquid and prevent oxidation, coffee liquid extracted at low temperature is sometimes transferred to a heating container and heated before drinking.
The coffee liquid in the area that comes into contact with the coffee kettle (such as a kettle) burns, and the sugar that is in contact with the coffee liquid becomes bitter, resulting in the inconvenience that the aroma and taste deteriorate.

Furthermore, in order to enjoy the rich aroma and full-bodied taste, we use coffee powder obtained from high-quality coffee beans to extract high-quality coffee liquid and store it by keeping it warm or heating it so that it can be drunk at any time. However, even if the coffee liquid is good, if it is kept in a warm or insulated state, the coffee oil will escape due to the heat and the aroma will decrease, and the coffee liquid will oxidize. The taste deteriorates, rendering the use of high-quality coffee beans meaningless.

The present invention was developed based on the above-mentioned circumstances and the fact that if coffee liquid is extracted at a relatively low temperature, heat is released and stored, and the coffee liquid is instantly heated when drinking, it becomes delicious. To provide a useful coffee liquid extraction device in which the aroma of the liquid does not decrease, there is little fear of oxidation, and there is little fear that sugar contained in the coffee liquid will become bitter.

Means for Solving the Problems In order to achieve the above object, the present invention installs a heat dissipation tank for coffee liquid next to the coffee dripper into which hot water is poured in a shower, and connects the tank with a dripper. We propose a method in which the liquid pipe is connected to an instantaneous heater, and the instantaneous heater is equipped with a spouting pipe with a tap.

Function: Since the present invention comprises the above-mentioned means, hot water is poured all over the coffee powder in the coffee dripper, and the coffee liquid extracted at low temperature is stored in the heat radiation tank and cooled to room temperature. When the cup is opened, the room-temperature coffee liquid in the heat dissipation tank is sent to the instant heater through the liquid supply pipe, and heated to a high temperature in a short time by operating the instant heater. Once the cup is opened, the heated coffee liquid is poured out from the spout pipe.

Embodiment The coffee dripper 1 has a well-known structure in which a cloth or paper is hung from a mouth frame, or is stretched from one end of a tube body, and the inside thereof is filled with coffee powder. The coffee dripper 1 pours hot water heated to about 80°C in a shower-like manner, and the configuration for this shower-like discharge is as shown in the illustrated example.
In addition to attaching the shower head 801 to the outflow part of the dripper itself, a shower device (for example, a porous pipe (not shown) is arranged radially from the center of the spout toward the spout, and a shower head 801 is attached to the spout of the dripper itself. A shower device constructed by installing perforated pipes along the line, and connecting these perforated pipes to each other and to the hot water pipe)
It is conceivable to configure the following. The heat radiation tank 2 is
This is to quickly cool the coffee liquid extracted at a low temperature with hot water of about 80℃ to room temperature and store the heat. In addition to preventing the coffee liquid from oxidizing and degrading the flavor due to heat, etc., it also allows you to obtain the necessary amount of coffee liquid for multiple people when you need it. Make it. The heat dissipation tank is made of a material that can dissipate heat as quickly as possible and is not eroded by the coffee liquid (for example, stainless steel plate, ceramics, glass, etc.), and is disposed next to the coffee dripper 1, and is placed next to the coffee dripper 1. This allows the coffee liquid to be stored. Although the heat radiation tank 2 in the illustrated example does not have an opening/closing lid, it may be provided so that it can be opened and closed as needed.
To prevent unnecessary evaporation of coffee liquid and to prevent hygiene problems from occurring. Instant heater 4
is used to prevent oxidation of coffee liquid, prevent loss of aroma, prevent burning, and shorten heating time. It consists of a type heater (for example, a microwave oven), and is connected to the heat radiation tank 2 by a liquid sending pipe 3 having a pot 5, and is also provided with a pouring pipe 6 having a pot 7, and when the pot 5 is operated, the heat radiation tank The coffee liquid in 2 is supplied, and Kotoku 7
By operating the , the heated coffee liquid can be poured out. The instantaneous heater 4 is configured such that the outflow side end of the liquid sending pipe 3 faces inside thereof, and the coffee liquid in the heat radiation tank 2 is poured into a heating container or coffee cup set inside the instant heater 4. . Although not shown, the heating container for coffee liquid that is used in and out of the instant heater 4 is a container (for example, a box-shaped, gutter-shaped container, etc.) for heating coffee liquid for multiple people at once. ) and a coffee cup for heating coffee liquid for one person, and in the case of a container for multiple people, an openable and closable outlet (not shown) for attaching and detaching to the inflow side end of the spouting pipe 6. is provided at the bottom, and by opening the outlet and operating the pot 7, the heated coffee liquid in the container is poured out from the pouring pipe 6. The inflow side end of the spouting pipe 6 faces the inside of the instant heater 4, and the outflow port provided in the heating container for multiple people is attached and removed, and by opening the outflow port and operating the pot 7. Then, the heated coffee liquid is poured out.

In the embodiments described above, the arrangement of each member and each device is not only a vertical line as shown in the figure, but also a horizontal line, an L-shaped arrangement, etc.

Effects of the invention Since the invention is constructed as described above, hot water is poured all over the coffee grounds in the coffee dripper, and the coffee liquid poured out at a low temperature is heat radiated and stored in the heat radiating tank and kept at room temperature. cooled down to Therefore,
The negative effects of a decrease in aroma and taste caused by storing coffee liquid under heat or heating can be eliminated, and high-quality coffee powder made from high-quality coffee beans can be used. Conventional inconveniences can be removed. When the cup is opened, the room-temperature coffee liquid in the heat dissipation tank is sent to the instant heater via the liquid pipe, and by operating the heater, it is heated to a high temperature in a short time and poured out. If you open the tube, it will be poured out. Therefore, high-temperature heating can be carried out efficiently without reducing the aroma or oxidizing it, and furthermore, without burning the sugar in the coffee liquid, so you can enjoy delicious coffee with a rich aroma and rich taste. be able to.
