Description

[Detailed explanation of the invention] This invention obtains coffee by dripping hot water onto coffee grounds.
Regarding the so-called drip-type coffee boiler, it supplies the most suitable hot water for filtering coffee, obtains delicious coffee, visually enjoys the way the coffee is made, and discharges hot water. The purpose is to prevent the risk of burns due to incorrect operation by making the information visible.

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

In this case, the water in the water tank is discharged through a sealed heating pipe and water rising pipe and dripped directly onto the coffee grounds, so you can see no movement of hot water and check whether the discharge is complete or whether it is working properly. It has the disadvantage that it cannot be visually confirmed.

Therefore, when the coffee basket is removed in the middle of dispensing, there is a risk of hot water gushing out and causing burns.

The present invention solves the above-mentioned drawbacks of the conventional coffee boiler, makes it possible to see the spouted water, simplifies its configuration, and minimizes the drop in the temperature of the dripping water to obtain delicious coffee. Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes an upper container having a generally upside-down shape, and has a water tank portion 2 and an eaves portion 3, and the eaves portion 3 is provided with a hole into which a cylindrical water sprinkling lid base 4 engages. There is.

'The sprinkler lid 4 has a substantially truncated conical shape with an upper opening larger than a lower opening, and is molded from transparent or translucent glass or resin with a gasket 5 interposed at the upper end, and has a concave lower surface. The ring 7 is fixed to the eaves 3 of the upper container 1 so as to press against the flange 8 provided on the outer periphery of the sprinkler lid 6 with a ring 7 having an L-shaped cross section.

A hole 9 is provided in the wall surface of the sprinkler lid stand 4, and a discharge pipe 10 made of a material such as silicone rubber is penetrated therethrough and attached in a watertight manner.

The discharge pipe 10 has one end connected to a rising water pipe 11, and the other end connected to an upward discharge hole 12 located approximately at the lower center of the sprinkler lid 6.
A downward discharge hole 12' is provided.

Reference numeral 13 denotes a heating element formed by die-casting aluminum, and includes a heating element 14 such as a sheathed heater and a heating pipe 15.

One end of the heating pipe 15 is connected to the water tank 2 of the upper container 1 via a check valve 16 that prevents water from flowing back from the heating pipe 15 toward the water tank 2, and the other end is connected to the water riser pipe 11. is connected to.

A glass container 17 is placed on the heating element 13 via a heat insulating plate 18 made of a material with good thermal conductivity such as an aluminum plate, and a coffee basket 19 is placed on top.

The coffee basket 19 has a V-shaped filtration part 22 in the center of which is placed a filter paper 20 and coffee powder 21 is placed therein, and a hole 23 is provided in the bottom of the filtration part 22.

24 is a lower container that covers the heating element 13 and the like, and 25 is an upper lid.

Reference numeral 26 denotes a cover of the eaves portion 3 with the water spray lid 6 opened.

Note that the internal space surrounded by the sprinkler lid 6 and the sprinkler lid stand 4 is provided in a state in which it is communicated with the outside air.

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

When coffee basket 19 is lined with filter paper 20 and coffee grounds 21 are placed, water is poured into water tank 2 and electricity is applied to heating element 14, water flowing into heating pipe 15 is heated and boils to generate steam and bubbles. and rapidly expands in volume.

The expanded hot water is prevented from flowing in the direction of the water tank 2 by the check valve 16, rises up the water rising pipe 11, and reaches the discharge pipe 10.
It is ejected from the discharge hole 12.12'.

The hot water spouted from the upward discharge hole 12' collides with the sprinkling lid 6, spreads, falls onto the sprinkling lid stand 4, and drips onto the coffee grounds 21.

At this time, the water sprinkler cover stand 4 is wider than the upper opening 4' and the lower opening 4''.
Since the water is small, the water dispersed by the dispersion lid 6 is collected again and drips in a skewer shape at the end of the lower opening 4''.

Moreover, since the hot water spouted from the discharge hole 12 hits the transparent sprinkler lid 6 and spreads, the operation can be confirmed.

Furthermore, the lower opening 4'' of the truncated cone-shaped sprinkler lid base 4 is made smaller than the upper opening 4', and the dispersed hot water is collected again, so that the skewer-shaped hot water that adheres to the end of the lower opening 4'' is Drops quickly without staying for a long time.

Therefore, the time for heat to radiate in the air is shortened, preventing the water temperature from dropping.

Furthermore, since there is little air convection in the sprinkler lid 6, a high temperature atmosphere is maintained, and the heat radiation of the hot water being diffused is small, so that the high temperature hot water drips onto the coffee powder 21, and delicious coffee can be extracted.

In addition, the hot water diffusion part is formed by a concave sprinkler lid 6 and a cylindrical sprinkler lid stand 4, and the manufacturing mold can be machined with a two-sided mold, resulting in high productivity, low cost, and easy assembly. .

As is clear from the above explanation, according to the present invention, the state of hot water being discharged can be visually observed, operation errors are not caused and it is safe, and the discharged hot water is poured onto coffee grounds in a short time.
In addition, since the space inside the sprinkling lid is maintained at a high temperature atmosphere, the hot water is poured onto the coffee grounds, resulting in great-tasting coffee, which is of great practical value.
