DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general household coffee machine.

[0002]

2. Description of the Related Art Conventionally, the following coffee brewers are known. FIG. 6 shows the structure of a conventional coffee brewer. The main body 1 has a water tank 2, and the bottom of the water tank 2 is connected to a water pipe 3 having a check valve 15 built therein. Through a lower portion of the main body 1 to a pouring port 6 provided in an upper projecting portion 5 of the main body 1. The sheathed heater 4 is cast into an aluminum heat conductive member 7, and a heat insulating plate 9 fixed to the main body 1 by a heat insulating plate mounting frame 8 is mounted on an upper part, and a water pipe 3 is mounted on a lower part.

[0003] A glass container 10 is placed on the heat insulating plate 9, and a band 11 is wound around the outer surface of the container 10 to fix a handle 12. A coffee basket 13 having a hole 19 at the bottom and a coffee basket lid 14 having a sprinkler plate 20 at the center are placed.

Reference numeral 16 denotes a handle of the coffee basket 13, 17 denotes a handle of the coffee basket lid 14, 18
Is a thermostat attached to the heat conducting member 7 for controlling the temperature of the sheath heater 4. Reference numeral 21 denotes a spherical activated carbon filter, which is mounted on the sprinkler plate 20.

FIG. 7 is a sectional view of a main part showing details of the vicinity of the spherical activated carbon filter 21, wherein 22 is a spherical activated carbon case lid, 23 is a mesh, 24 is a spherical activated carbon case, and 2 is a spherical activated carbon case.
5 is a spherical activated carbon. 26 is a spherical activated carbon case lid 22
And rests on the upper surface of the coffee basket lid 14. 27 is a boss of the coffee basket lid 14.

[0006] The operation of the coffee brewer configured as described above will be described below. When a paper filter is set in a coffee basket 13 and coffee grounds are put therein, water is put in a water tank 2 and electricity is supplied to a sheath heater 4. The water in the water pipe 3 in this portion boils through the heat conducting member 7. By the action of the check valve 15, the steam pressure is increased and hot water can be dropped from the pouring port 6. Then, the hot water dropped from the pouring port 6 passes through the spherical activated carbon filter 21 to remove the calcium component in the hot water, and then the hot water is once retained in a gap between the lower end surface 28 and the water spray plate 20 by surface tension.

Next, when hot water is dripped from the pouring port 6, pressure is uniformly applied to the retained hot water by 360 degrees, and the hot water jumps out and uniformly applies on the coffee powder. A concentrated coffee liquor can be extracted.

[0008]

The coffee brewer constructed as described above has the following problems. Since the spherical activated carbon filter is formed on the watering plate in the center of the coffee basket lid, the capacity of the spherical activated carbon case is limited, that is, the amount of spherical activated carbon incorporated is limited, and the calcium component in the hot water is reduced. There is a limit to the improvement of the removal rate of

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a coffee brewing machine having a spherical activated carbon filter having a high removal rate of calcium components in hot water.

[0010]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention has a spherical activated carbon filter incorporated in a coffee basket lid for removing calcium components in hot water, and a spherical activated carbon filter is provided below the spherical activated carbon filter. A coffee boiler is provided with a sprinkling plate.

As a result, a coffee brewing apparatus having a spherical activated carbon filter with a high removal rate of the calcium component in the hot water can be obtained.

According to a second aspect of the present invention, there is provided a main body including a water tank and a heating means for heating water, a coffee basket for extracting coffee, and a sprinkler plate mounted on an upper portion of the coffee basket. Comprising a coffee basket lid having a spherical activated carbon filter,
A charcoal filter is a sphere that removes calcium components in hot water.
Activated carbon and a spherical activated carbon case for storing the spherical activated carbon.
The spherical activated carbon case has a spherical shape around the upper opening
Hold the mesh placed on top of the activated carbon, and
The coffee
A coffee boiler which engages with a basket lid
Turn the coffee basket lid upside down
Also that having a effect of spherical activated carbon filters will not be falling.

[0014]

(Embodiment 1) FIG. 1 shows a first embodiment of the present invention. FIG. 2 is a sectional view of a main part. Reference numeral 21 denotes a spherical activated carbon filter, which is engaged with the coffee basket lid 14 by the claws 30 and the ribs 35 on the sprinkling plate 20 so as to hold the spherical activated carbon case 24. That is, even if the coffee basket lid 14 is turned over, the spherical activated carbon filter 21
Will not fall. In addition, when compared with the configuration of the conventional coffee boiler, the spherical activated carbon case lid 22 is not required, and the number of parts can be reduced and cost can be reduced. 24 is a spherical activated carbon case, 31 is an inlet side mesh, 32 is an outlet side mesh, 33 is a spherical activated carbon sprinkler plate, 25 is a spherical activated carbon, a spherical activated carbon case 24 holding a spherical activated carbon filter 21 and a spherical activated carbon case. 2
5, and a mesh 31 is provided.

That is, the spherical activated carbon case 24 is held by engagement, and the spherical activated carbon case 24 and the spherical activated carbon 25
Since the mesh 31 is provided between the meshes 31, the mesh 31 can be easily positioned, and does not cause displacement.

The operation will be described below. When hot water drops from the pouring port 6 onto the spherical activated carbon filter 21, the hot water hits the spherical activated carbon sprinkling plate 33, is scattered in all directions, and then passes through the mesh 32. At this time, as compared with the case where the spherical activated carbon sprinkler plate 33 is not provided, the distance and time for hot water to pass between the spherical activated carbons are longer, and the removal rate of the calcium component of the hot water is increased. Then, the hot water is once held in the gap between the lower end surface 28 and the sprinkling plate 20 by the surface tension.

Next, when hot water is dripped from the pouring opening 6, pressure is applied uniformly to the retained hot water by 360 degrees, and the hot water jumps out and is evenly applied on the coffee powder to extract a coffee liquid having an appropriate concentration. be able to. FIG. 3 shows a perspective view of the spherical activated carbon filter 21. Reference numeral 30 denotes a nail, and reference numeral 35 denotes a rib. The coffee basket lid 14 is provided so as to be engaged by the claw 30 and the rib 35.
