Description

[Detailed description of the invention] This invention relates to a filter for coffee, etc., and its purpose is to uniformly diffuse hot water poured into the filter, and to filter specific parts of coffee powder, tea, etc. The aim is to obtain a device that concentrates only on objects and does not cause them to fall.

Traditionally, when brewing coffee, boiling water was poured gently over the coffee grounds stored in a filter for several minutes, but if the hot water was concentrated on only one part of the coffee grounds, only that part of the coffee grounds would be extracted. The coffee powder swells, and there is a part in the coffee powder where the hot water drips, leaving coffee powder that does not fully touch the hot water, making it difficult to obtain delicious coffee and also being uneconomical.

In order to deal with this difficulty, there has been a system in which a diffuser plate 21 is provided below the filter lid 20 corresponding to the pouring port 19 of the hot water supply vibrator to disperse hot water, as shown in FIG.

The diffuser plate 21 of this filter is formed into a spherical shape with a convex upper surface, and the hot water supplied from the pouring port 19 flows through the diffuser plate 21.
1, it is configured to be dispersed along a spherical surface and poured into coffee powder.

However, if the centers of the spout 19 and the diffuser plate 21 are even slightly misaligned, the hot water will not be distributed evenly and will drip concentratedly in one direction, resulting in the inability to function as a diffuser plate. Hot water could not be dripped directly under the diffusion plate 21, and uniform pouring could not be expected.

The present invention eliminates the above-mentioned conventional drawbacks, and its structure will be explained below with reference to the drawings shown as embodiments.

Reference numeral 1 denotes a filter main body placed on a glass container 2, and has a filter 3 such as a Tetoron mesh on the lower surface.

4 is a lid placed on the filter body 1; 5 is a diffusion plate provided in the center of the lid 4; this diffusion plate 5 has a generally spherical shape with a concave upper surface; A hole 22 is formed,
A small hole 6 is provided in the center.

The small hole 6 has a smaller opening area than the pouring hole 22,
Furthermore, the number of outflows of hot water through the small holes 6 is set to be smaller than the number of hot water supply acids.

7 is coffee powder put into the filter body 1.

8 is the main body of the coffee boiler, 9 is a heating element made of aluminum die-casting in which a heating vibrator 10 and a sheathed heater 11 are integrally provided, and 12 is a heat insulating plate made of a material with good thermal conductivity such as an aluminum plate. , formed on the upper surface of the heating body 9 (
・Ru.

A glass container is placed on this heat insulating plate 12.

Reference numeral 13 denotes a water tank having a check valve 14 at its lower part, and its upper part extends in the form of a canopy above the installation part of the heat insulating plate 12 of the main body 8.

Reference numeral 15 represents a connecting member connecting the heating vibrator 10 and the water tank 13; 16 represents a water raising vibrator that guides the water heated by the heating element 9 to the filter 1; It is formed along the tank 13, and the discharge port 17 at the other end opens at the canopy of the water tank 13 and corresponds to the diffusion plate 5 provided on the lid 4 of the filter 1.

18 is the lid of the water tank.

In the above configuration, when the filter 1 is filled with coffee powder 7, the water tank 13 is filled with water, and the sheathed heater 11 is energized, the water in the water tank 13 is supplied to the heating pipe 10 and heated by the sheathed heater 11. The pressure inside the heating pipe 10 increases due to the bubbles, and the water passes through the rising pipe 16 and is discharged from the discharge port 17.

The discharged hot water is poured into a diffusion plate 5 provided on the lid 4 of the filter 1, and part of the hot water drips onto the coffee powder T through a small hole 6 in the center, but part of the hot water has a concave top surface. It accumulates on the diffuser plate 5.

When hot water is further poured, it overflows from the outer periphery of the diffusion plate 5 and drips uniformly onto the coffee powder 7 from the pouring hole 22.

At this time, even if the alignment between the discharge port 17 and the diffuser plate 5 is slightly misaligned, a small amount of hot water is stored on the top surface of the diffuser plate 5 and dripped from the outer periphery, so as long as it is within the range of the diffuser plate 5, there will be no problem and the coffee will not be affected. The powder 7 can be poured uniformly.

The poured hot water permeates the coffee powder 7 and extracts the ingredients, and becomes coffee liquid through the filter 3 and accumulates in the glass container.

Moreover, when the discharge from the discharge port 17 is finished, the hot water on the diffusion plate 5 flows out from the small hole 6, and all the hot water is removed from the coffee grounds 7.
is dripped on.

Since the hot water thus discharged is always uniformly poured onto the coffee powder 7, a rich and delicious coffee liquid can be obtained without failure.

Incidentally, in the above embodiment, a diffusion plate attached to a coffee boiler was described, but the present invention is not particularly limited to this.

Further, although one small hole is provided in the central portion of the diffuser plate, a plurality of small holes may be provided in the concave portion of the diffuser plate, and modifications may be made without departing from the gist.

As is clear from the above embodiments, the filter for coffee, etc. according to the present invention has a diffusion plate in the center of the lid, which has an upwardly concave, substantially spherical shape and a small hole in the center. Even if the position of the hot water poured into the filter is slightly off, the hot water can be distributed evenly without dripping on the filter, and there is no residual water on the diffuser plate, resulting in a delicious drink. , its practical effects are great.
