Description

[Detailed description of the invention] This invention relates to an auxiliary tool for brewing coffee, tea, etc.

A conventional siphon type extractor is comprised of a heating section 1 at the bottom, a flask section 3 at the middle, and a funnel section 6 fitted with a filter 4 closely fixed thereto.

The general method of use is to pour a predetermined amount of hot water 2 into the lower flask 3, then pour the specified amount of coffee powder or black tea 5 (hereinafter referred to as powder) into the funnel 6, which is equipped with a filter 4 in advance, and then fix it tightly to the flask. Then, the pressure inside the flask 3 is increased by heating from the bottom of the flask, and the hot water 2 is guided through the filter to the upper funnel 6 to extract the powder 5. After a predetermined period of time, the fire is extinguished and the mixture is extracted again into the reduced pressure flask. The liquid is sucked and filtered.

To explain the extraction operation in more detail, after the hot water 2 begins to rise through the filter 4 into the upper funnel 6, the powder floating on the top of the hot water is pressed down with a bamboo spatula etc. to the extent that it becomes wet with the hot water.
Furthermore, after the hot water has risen, stir slowly with a bamboo spatula, etc. to disperse the entire powder and enhance the extraction effect.After about 1 minute, turn off the heat, and suck the extract into the reduced pressure flask again and filter. .

During suction and filtration, powder in the extract accumulates on the top of the filter 4 at the bottom of the funnel, impeding the filtration speed of the extract, resulting in longer extraction times and a bitter taste. It was necessary to rotate the hot water to speed up the filtration rate.

According to this method, the person making the coffee, etc. is restrained from fixing the funnel tightly to the flask until the extraction is complete, and the taste of the extracted coffee, etc. varies from person to person depending on the intensity of stirring with a bamboo spatula etc. Also, since the upper part of the funnel is open, there are disadvantages in that the temperature of the liquid drops, the aroma escapes, and the steaming effect cannot be expected.

This invention aimed to eliminate the above drawbacks with a simple device.

To explain this idea with reference to the drawings, a blade having a hole or notch inside the funnel 6 as shown in FIG. 1 and having a diameter slightly smaller than the inner diameter of the funnel 6 and a cross section as shown in FIG. , and a hole with a diameter slightly smaller than the inner diameter of the funnel and slightly larger than the support 9 in the center is provided at the top, and a lid 8 is provided that fits into the support 9 and can float depending on the rise and fall of the liquid level; The upper part is bent along the inner diameter of the funnel to center the entire device, and a device that can be detached from the funnel is inserted and installed in the funnel 6 as shown in FIG. 3.

According to this invention, as the hot water 2 rises from the lower flask 3 through the filter 4, the powder 5 floating on the surface of the hot water is once pressed down by the lower part of the blade 7, and the powder 5 is automatically moistened, so that the hot water is completely After rising completely, the holes or notches in the blades 7 create a turbulent flow of hot water, which automatically stirs the powder 5 to enhance the extraction effect. 8 prevents the liquid temperature from dropping and the aroma from escaping, and can also be expected to have a steaming effect.

A single blade is effective, but as shown in Figure 1.3,
The effect is further enhanced by arranging multiple sheets in a spiral or step-like manner, and it is better to arrange the holes or notches alternately rather than on the same vertical line as shown in Figure 2.
As the water level rises, the floating powder is pressed down one after another by the lower part of the blade, making it even more effective.

Further, the spacing between the blades may be changed depending on the amount of liquid.

Compared to the conventional method, this device suctions the extract and filtrate.The powder is caught on the top of the blade at the right time, reducing the accumulation of powder on the top of the filter, accelerating the filtration speed of the extract, and making coffee etc. For those who wish to drink water, they only need to turn off the flame after a predetermined period of time after the hot water rises in the funnel.In addition, to prevent variations in taste due to individual differences, even after the brewing is finished, the funnel can be turned upside down for normal cleaning. This feature allows the device to be easily taken out and cleaned.

Claims (1)

[Scope of utility model registration request] Inside the funnel 6, one or more blades 7 made of an inorganic material such as metal, plastic, ceramics, or wood and having a diameter slightly smaller than the inner diameter of the funnel and having holes or notches are arranged in a spiral or step-like manner. A hole with a diameter slightly smaller than the inner diameter of the funnel and slightly larger than the support 9 in the center is provided in the upper part, and a lid 8 is provided that fits into the support 9 and can float depending on the rise and fall of the liquid level, and the upper stage of the support 9 is attached to the funnel. This brewing aid for coffee, tea, etc. is bent along the inner diameter to center the entire device, and the entire device is detachable from the funnel 6.
