Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a coffee extractor for pouring coffee grounds over a wide area.
[0002]
[Prior art]
When pouring coffee powder pulverized by a mill or the like, it is common to store the coffee powder in a paper filter, pour boiling water over it, and extract it while slightly unevenness.
[0003]
In addition, for business use and mania, coffee powder is stored in a flannel (cloth) filter, and hot water is drawn from above the pouring port of the pouring pot by drawing in the shape of a “no”. I have to.
[0004]
When the hot water is extracted by such a pouring method, the hot water is uniformly poured into the entire area of the coffee powder, so that the coffee powder can be used for the extraction without unevenness, and the uniform hot water is poured into the coffee powder. It is possible to extract a rich fragrance and rich coffee.
[0005]
However, the above-mentioned pouring method seems to be simple in practice, but pouring it while drawing a `` no '' on the coffee powder contained in a not so large flannel filter requires hot kneading. However, it is said that it is difficult for an amateur to pour water using a normal kettle or pouring pot.
[0006]
By the way, a conventional coffee boiler in which coffee powder is stored in a basket having a fine filter net by using a normal filter, as shown in Japanese Patent Application Laid-Open No. 61-73620, is used. A hot water diffusing plate is provided in a pouring section provided above so that hot water can be poured into the entire area of the coffee powder.
[0007]
[Problems to be solved by the invention]
In the prior art as described above, although the hot water is certainly dispersed by the diffusion plate, the hot water is simultaneously poured into the entire area of the coffee powder to disperse the hot water, so that it is not possible to take a sufficient amount of time for the hot water, and the hot water is not supplied. The extraction was completed without sufficiently penetrating into the coffee powder, resulting in no scent or richness.
[0008]
In addition, by automatically performing a pouring method such as drawing a “no” character by a mechanic as described above, it is possible to extract scented, rich, and savory coffee.
[0009]
However, actually, the mechanism for rotating or rocking the pouring section back and forth and right and left is very complicated, and is liable to cause malfunction or failure.
[0010]
According to the present invention, whirlpool pouring is performed by a simple mechanism, and malfunction or failure is prevented from occurring.
[0011]
[Means for Solving the Problems]
One of the present invention includes a first motor fixed to a chassis, a second motor connected to a rotation shaft of the first motor, and a pouring pipe attached to a rotation shaft of the second motor. The first motor and the second motor are operated by sequence control to pour coffee powder while turning the pouring pipe in a spiral shape.
[0012]
The first motor is fixed to a first holder attached to a chassis, the second motor is fixed to a second holder connected to a rotation shaft of the first motor, and a rotation shaft of the first motor is operated. The second holder is rotated by the rotation, and at the same time, the second motor is operated to pour the coffee powder while swirling the pouring pipe in a spiral shape.
[0013]
The rotation axis of the first motor and the rotation axis of the second motor are arranged so as to be orthogonal to each other, and the pouring pipe is swung in the X-axis direction by one motor and swung in the Y-axis direction by the other motor. Pouring coffee powder while moving and swirling in a spiral shape.

[0033]
First, the cups (3), (3) and (3) are mounted on the mounting table (2), and the flannel filter (5) containing a predetermined amount of coffee powder is mounted on the filter holder (4). When the 1 pouring button (7) is operated, the first pouring valve (18) is opened, and at the same time, the timer (36) starts counting the execution time of the pouring process.
[0034]
The operation of the first motor (26) and the second motor (31) by the execution of the pouring program by the microcomputer (35) causes the pouring pipe (19) to move from the solid line position in FIG. Pour the coffee powder while drawing the letter "no" as shown in the black painted area.
[0035]
The movement of the pouring pipe (19) at this time is oscillated in the X-axis direction by the first motor (26), oscillated in the Y-axis direction by the second motor (31), and the timer (36) counts. Until the end, the pouring program is ended by turning in a zigzag manner in the shape of the "" shown in FIG. During this time, the pouring pipe (19) swings as shown by a chain line in FIGS.
[0036]
During pouring, when the amount of hot water stored in the hot water tank (12) falls below the reference water level, the hot water pump (16) is operated to supply hot water in the hot water storage tank (9) into the hot water tank (12).
[0037]
Eventually, the count of the timer (36) ends, and at the same time, the first motor (26) and the second motor (31) stop to end a series of pouring programs.
[0038]
In the present invention, the movement of the pouring pipe at the time of pouring has been described as drawing a letter "no", but the movement is close to the letter "no", for example, turning in a whirlwind state from the center. Is fine. In short, what is necessary is just to be able to turn in a winding shape.
[0039]
【The invention's effect】
As described above, the present invention includes the first motor fixed to the chassis, the second motor connected to the rotating shaft of the first motor, and the pouring pipe attached to the rotating shaft of the second motor. Since the first and second motors are used to pour the coffee powder while rotating the pouring pipe in a whirlwind shape, the whirlpool is free from malfunction and failure without using a complicated link mechanism. Pouring can be performed.
[0040]
In particular, since the pouring pipe is turned by two motors, each motor is delicately controlled independently to turn the pouring into a spiral shape, for example, an elliptical or square shape. be able to.
[0041]
Then, since only the first motor of the two motors is fixed to the chassis, the fixed portion is of course one position, and the position of the second motor must be taken into account by changing the fixing position to the chassis. It is possible to change the pouring state of the winding shape.
[0042]
In addition, the rotation of the rotary shaft accompanying the operation of the first motor rotates the second holder to which the second motor is fixed, and simultaneously operates the second motor to turn the pouring pipe into a spiral shape. Thus, the operation of the first motor can be accurately transmitted to the second motor side, so that the pouring pipe provided on the second motor side can be turned to the prescribed position.
[0043]
Further, the rotation axis of the first motor and the rotation axis of the second motor are arranged to be orthogonal to each other, and the pouring pipe is swung in the X-axis direction by one motor and in the Y-axis direction by the other motor. Since the molten metal is swirled and poured, it is possible to independently control the swing in the X-axis direction and the Y-axis direction. As a result, it is possible to add a change to the whirlwind-like rotation. For example, an elliptical swirl can be realized by making a large swirl turn or making the movement in one of the axial directions faster or slower.
