Description

[Detailed Description of the Invention] The present invention relates to a coffee boiler, which supplies the most suitable hot water for filtering coffee to obtain delicious coffee.

In general, a drip coffee boiler heats water supplied from a water tank in a heating pipe, raises the water in the pipe using the power of air bubbles and steam, and uses the hot water that rises in the pipe to add coffee powder. Coffee is obtained by discharging and dripping from above the basket.

In this case, the coffee powder is stored in the basket as needed, from one scoop to several cups, depending on the needs of the drinker, but conventionally, the dripping of hot water is always constant, making it impossible to obtain a satisfying and delicious cup of coffee. There wasn't.

Ideally, the hot water should be poured evenly over the coffee grounds, but if you drip hot water concentrated on only a few spots, too much coffee will come out in the areas where the hot water is applied, resulting in bad-tasting coffee. Also, in areas where hot water cannot be used directly, coffee cannot be extracted sufficiently, making it uneconomical.

On the other hand, if the hot water is dispersed too widely and spills onto areas other than the coffee grounds, the coffee will have a weak concentration and will be extremely uneconomical to extract.

The present invention solves the above-mentioned conventional drawbacks, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a water tank, which has a lid 2 at its upper opening and a check valve 3 at its bottom.

4 is a heating pipe, one end of which is connected to the water tank 1 via the check valve 3, and the other end connected to the water rising pipe 5.

Reference numeral 6 denotes a heating element made of aluminum die-casting, and includes a heating element, for example, a sheathed heater 7 and the heating pipe 4.

Reference numeral 8 denotes a generally inverted-shaped container, and a spray lid 10 having a generally hemispherical shape and a downwardly concave surface is attached to the eaves 9, and a discharge pipe 11 connected to the water rising pipe 5.
A spout 12 is provided below the discharge pipe 11.

This spout 12 has a protrusion 13 smaller than the maximum diameter of the sprinkler lid 10, and also has several notches 14.

Reference numeral 15 denotes a rotatable adjustment spout that is closely supported at the lower part of the spout 12 and has a protrusion 16 and a notch 17 corresponding to the protrusion 13 and notch 14 of the spout 12. .

Further, an operating piece 18 is provided on the outer periphery of the adjustment spout 15, and a display portion 9 is provided on the eaves 9 of the container 8.
A is formed and a scale corresponding to the number of cups is displayed.

19 is a coffee basket in the shape of an approximately inverted triangular pyramid, and the discharge pipe 11
A glass container 20 is provided below the glass container 20 .

The coffee basket 19 has a hole 21 at the bottom.
A filter paper 22 is attached inside and coffee powder 23 is put therein.

The glass container 20 is placed on the heating body 6 via a heat insulating plate 24 made of a material with good thermal conductivity such as an aluminum plate.

25 is a base that covers the heating element, 26 is a thermostat for keeping warm, 27 is an upper lid, and 28 is a handle of the glass container 20.

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

A filter paper 22 is placed in a coffee basket 19, and a desired number of cups of coffee powder 23 is put therein.

If the number of cups is large, rotate the operation piece 18 of the adjustment spout 15 to set it to a large scale on the display section 29.

Then, the notch 14 of the spout 12 and the notch 17 of the adjustment spout 15 overlap, and the spout 12 becomes fully open.

Next, the coffee basket 19 is placed on the glass container 20 and placed on the heat insulating plate 24, and when the water tank 1 is filled with water and the power is turned on, water flows from the water tank 1 through the check valve 3 to the sheathed heater 7. It is heated, boils, generates steam and bubbles, and rapidly expands in volume.

Since the expanded hot water is prevented from flowing back toward the water tank 1 by the check valve 3, it rises through the rising pipe 5 and is jetted out from the discharge pipe 11 one after another.

The hot water spouted upward collides with the sprinkling lid 10 and disperses, releasing limescale etc. in the hot water into the air, passes through the spout 12 and the adjustment spout 15, and drips evenly onto the coffee grounds 23 in the coffee basket 19. Extract coffee ingredients and pass through paper filter
The coffee is filtered through 22 and flows out from the hole 21 into the glass container 20 to extract delicious coffee.

When the water in the heating pipe 4 runs out, the temperature of the heating element 6 rises rapidly, and the thermostart 26 operates to keep the temperature of the heating element 6 constant, so that the coffee in the glass container 20 is kept at a constant temperature. drooping

In addition, when the desired number of cups is small, if the operation piece 18 of the adjustment spout 15 is set to a small scale on the display section 29, the notch 14 of the spout 12 and the protrusion 16 of the adjustment spout 15 overlap, The opening of the spout 12 is covered, and the diameter of the opening is reduced.

In this state, the hot water spouted from the discharge pipe 11 is dispersed by the sprinkler lid 10 and drips into the spout 12, but the hot water spouted from the spout 12 and the adjustment spout 1
5 and drips onto the coffee powder 23 in the coffee basket 19 from the partial force of the small opening diameter.

On the other hand, since the number of cups of coffee powder 23 is small, the coffee powder 23 is stored at the bottom of the coffee basket 19 having a substantially inverted triangular pyramid shape, and the area of the upper surface of the coffee powder 23 to be dropped is small, so that the above-mentioned operation By reducing the dispersion of the discharged water, you can create the ideal way to pour hot water and get delicious coffee.

According to the above embodiment, the spout 12 and the adjustment spout 15 are configured with notches.1. However, a generally well-known glue mechanism such as a camera may be used, and it goes without saying that the invention may be modified as appropriate without departing from the spirit of the invention.

As is clear from the above description, according to the coffee boiler of the present invention, a spout for guiding discharged hot water is provided below the water rising pipe, and the opening diameter of this spout can be adjusted. This ensures the optimal dripping state of hot water for any number of cups desired by the drinker, allowing for economical extraction of delicious coffee.
