Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a coffee extractor that extracts coffee liquid by dropping cold water onto coffee grounds and heats the coffee liquid.

BACKGROUND OF THE INVENTION Conventionally, in this type of coffee brewer, as shown in FIG.
The coffee liquid that was dripped onto the coffee powder 24 stored in the extractor 23 and came out from the extraction hole 26 was stored in the 26, and was used as iced coffee or hot coffee. .

Problems to be Solved by the Invention With such a so-called cold brew brewer, when drinking hot coffee, it is necessary to transfer the coffee from the bottle to another container and heat it in a microwave or stove. There were problems such as difficulty in heating the liquid to an appropriate temperature of 80 to 86°C.

Means for Solving the Problems In order to solve the above problems, the present invention provides an extractor for storing coffee powder, a water container provided above the extractor,
The water container includes a dripping device connected to the water container, a heat-resistant glass bottle container disposed below the extractor for containing the coffee liquid, and a heating device that heats the bottom of the bottle. The bottle is provided with a temperature-sensitive member having temperature-sensitive history and color properties, thereby providing a means for visually determining that the bottle has been heated to an appropriate temperature.

Effect According to the above configuration, when the organic temperature-sensitive member printed on the bottle is heated, the primary colors gradually change, and when the coffee liquid is heated to an appropriate temperature of 80°C to 86°C, the color changes completely. It is designed to change color to a predetermined color.

Example Embodiments of the present invention will be described below based on the accompanying drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a coffee extractor main body, which has a base 2. As shown in FIGS. 3 is a tank for storing water, a tank lid 4 is placed on the top, and a dripping device 6 is connected to the bottom. Reference numeral 6 indicates an adjustment position of the dropping device 6.

Reference numeral 7 denotes an extractor, which has a water sprinkler 8 on its upper part and accommodates coffee powder 9 and a paper filter 10. 11 is a heat-resistant glass bottle, hand A
/13 is fixed. As shown in FIG.
is printed. The temperature-sensitive member that forms this water volume scale is made by encapsulating dye, color developer, and wax into microcapsules, and when the temperature rises, the organic color developer reacts with the dye and changes color. For example, the color changes from green to red.

It also has reversibility, returning from red to green when the temperature drops. Reference numeral 14 shown in FIG. 2 is a heating device, which is integrally formed with a sheathed heater 16 and has a thermostat 16 in the center that comes into contact with the bottom surface of the bottle. 16 is a mill device.

Next, the operation of the above configuration will be explained.

The water stored in the tank 3 is fed to the dripping device 6 and adjusted.
The dripping speed can be adjusted by rotating the knob 6. - Generally set to one drop per second. This dripping liquid is sprinkled on the coffee grounds 9 by a water sprinkler 8, extracting coffee components, and storing the extracted liquid in the P/L'11. The temperature of the extract at this time is approximately room temperature, so when drinking it as hot coffee, the heating device 14 may be energized to heat the bottle m1. In accordance with the temperature rise at this time, the water amount scale of the cup 11 changes color, and in the present invention, when the coffee temperature reaches 80° C., the color changes completely. Also, even if you leave it as is, the thermostat will set the temperature to 8.
It is kept at a temperature of 0°C to 86°C.

Effects of the Invention As is clear from the above configuration, according to the present invention, since the bottle containing the coffee liquid is provided with a temperature-sensitive member having a temperature-sensitive discoloration property, the temperature state of the coffee can be visually determined, regardless of the amount of coffee. This has great practical effects, such as being able to check the proper temperature and obtain the desired coffee temperature.
