Description

Description: FIELD OF THE INVENTION The present invention relates to an improvement of a beverage extraction device that is one component of a beverage supply device that extracts beverages from various beverage ingredients such as Japanese tea and coffee. It is a thing.

(Background of the invention) From the raw materials of various beverages such as Japanese tea, coffee, black tea, and oolong tea, the beverage is extracted and supplied, in the so-called beverage supply device, conventionally, in addition to the purpose of generally supplying the beverage economically, In particular, in the beverage supply device of the type that controls the amount of hot water while watching the amount of beverage that comes out in the cup, and the user can supply an arbitrary amount of beverage as he or she likes, the amount of hot water supplied is integrated to obtain a fixed amount. Every time the hot water is supplied, the raw material for extracting the beverage is replaced.

This is because the beverage extraction mechanism of the conventional beverage supply device is disclosed in Japanese Examined Patent Publication No. 30-3070, No. 51-36660, and No. 55-3.
No. 3328, No. 56-5523, No. 60-27527
Just as you can strain tea with your hands everyday, as you do in the No. issue, put the raw material into a filter shaped like a so-called tea strainer, and supply hot water from the top to filter the raw material. This is because the beverage is extracted in this manner, that is, when the beverage is extracted from the raw material in this way, the amount of raw material corresponding to one extraction is thin because the extraction time of the beverage is short. Since only a beverage can be obtained, for example, a method is adopted in which a large amount of raw material corresponding to 10 times of beverage supply is put into the filter at once and the raw material is replaced every time the beverage is supplied 10 times.

In this way, when extracting and providing a beverage from a large amount of raw material without replacing the raw material with a new one each time the beverage is supplied,
After providing the beverage at a predetermined fixed number of beverages or the amount of beverage provided, the beverage immediately after exchanging the raw material with a new one, a beverage that is much richer than the average is extracted, and also a certain number of beverages provided. By the time the beverage reaches the serving amount, beverages that are considerably thinner than the average are extracted, etc., the concentration of the beverage is not constant every time the beverage is served, and the beverage provided is too dark or simply colored. It will be provided as a watery drink like hot water, which is not preferable in any case.

Also, in the case of a tea strainer-shaped extraction container, when the extraction residue is discarded, the extraction container is turned upside down and the extraction residue in the container is discarded. There is also a problem that some of the extracted residue remains.

Therefore, each time a beverage is provided, the raw material for extracting the beverage is supplied from the raw material supply device to the extraction container in a required amount as a single batch, and the beverage is extracted by mixing with the hot water supplied from the hot water supply device. , If it is possible to reliably realize the operation of discarding the extraction dregs from the extraction container and discharging it to the box with a mechanism with a simple structure as a series of cycles, a beverage of stable quality that always contains certain beverage components Can be provided.

Furthermore, especially when Japanese tea is supplied, tea extracted by mixing the raw material already used once for extracting tea with hot water is more extracted than the case of extracting tea by mixing new raw material with hot water. However, it may be said to be delicious due to its astringency, and thus, in order to supply a beverage of good quality, depending on the characteristics of various teas, as a raw material that has already been extracted at least once. , If it is possible to extract a beverage by combining both new raw materials, for example, it is possible to supply a delicious beverage with the same fine-grained quality as a human hand, even though it is a fully automatic beverage supply device. Therefore, realization of a beverage brewing apparatus that enables complex beverage brewing operations economically and efficiently with a simple / simple mechanism has been an issue.

(Object of the invention) An object of the present invention is to solve the above-mentioned problems, and with a very simple structure, it is possible to extract a beverage from a raw material always with stable and good quality and efficiently in a short time. Submit a beverage brewing device.

(Characteristics of the invention) In order to achieve the above object, the present invention relates to a beverage extraction device in which hot water is infiltrated into a raw material to extract a beverage. The main surface of the container wall is a rotation surface formed by rotating the bus line as a generatrix about the straight line as an axis and the extraction container having an opening opening upward, and the extraction container A rotary shaft that is rotatably supported coaxially with the surface axis, a filter attached to a cutout portion of the container wall at one end of the extraction container, and a peripheral edge of the filter that is closely attached to the container wall of the extraction container. Then, a separator having a filter, which rotates and slides coaxially with the rotation axis of the extraction container inside the extraction container, an extraction container drive means for rotationally driving the extraction container, and a separator for rotationally driving the separator. A driving means is provided, so that the beverage is extracted while separating the new raw material and the raw material from which the beverage has already been extracted by the separator, and the extraction container is rotated around the rotation axis in an extremely simple manner. It is characterized in that the rotating operation separates the extracted beverage from the extracted residue, supplies the beverage, and discharges the extracted residue.

(Embodiment of the Invention) FIG. 2 is a front external view of a beverage extracting device 1 according to an embodiment of the present invention.

As shown in FIG. 2, the beverage extraction device 1 of the present invention is composed of an extraction container 2, a funnel 3 and an extraction residue discard box 4.

In the beverage brewing apparatus 1 of the present invention, as one embodiment, the brewing container 2 having a shape shown in FIG. 3 (a), that is, a hollow cylinder divided into two semicircles at both ends. In addition, the beverage is extracted by mixing a certain amount of raw materials for various beverages such as Japanese tea, coffee, black tea, and oolong tea measured by a raw material supply device (described later) with hot water measured by a hot water supply device (described later). Then, by rotating the brewing container 2 by the rotating shaft supporting the brewing container 2, the extracted beverage and the extracted dregs are separated, and the extracted beverage is passed through the funnel 3 to the cup 5 (see FIG. 2). ), And
A series of beverage extracting operations are performed so that the extracted residue is discarded and discharged into the box 4 (FIG. 2).

The raw material is supplied to the extraction container 2 from the guide tube 6 of the raw material supply device, and the hot water is supplied to the extraction container 2 from the tube 7 of the hot water supply device.

Extraction container 2 of beverage extraction device 1 according to an embodiment of the present invention
As shown in FIG. 3 (a), the two points B and C which are separated by a predetermined distance on the straight line a, and the U-shaped lines D, E, and F (shown by dotted lines) whose both ends are in contact with C are the bus lines. , A plane of revolution formed by rotating the generatrix about the straight line a by 180 degrees, that is, planes of semicircle 11 and 12 which are planes of revolution of the lines d and f.
And the pillar surface 13 which is the rotation surface of the wire e as the main container wall,
It has an opening 14 that opens upward.

A filter 15 for separating the extracted beverage and the extracted residue is attached to a part of the pillar surface 13 which is the bottom surface of the extraction container 2.

As shown as an example in FIG. 3 (b), the filter 15 is provided in a structure in which no protrusion is formed at a portion of the inner bottom surface of the extraction container 2 where the container wall is cut out.

As shown in FIG. 3 (c), the extraction container 2 has hollow rotating shafts 16 and 17 which are coaxial with the straight line a (FIG. 3a).
Attached to.

Inside the hollow rotating shafts 16 and 17, the separator shaft 1
8 penetrates the separator shaft 18 and the extraction container 2
The separator 19 is fixed so as to fit in the inside of the separator.

As shown in FIG. 1, a gear wheel 20 is fixed to a hollow rotary shaft 16 attached to the extraction container 2, and a separator shaft 18 to which a coupler 21, cams 22 and 23, and a separator 19 are attached. It penetrates through.

The separator shaft 18 is connected to the rotating shaft 24 of the motor M2 via a coupler 21.

Further, a coupler 26, a cam 27, and a gear 28 are attached to the rotary shaft 25, and the gear 28 is a hollow rotary shaft 1.
6 meshes with a gear 20 attached to the gear 6. Since the coupler 26 is connected to the rotary shaft 29 of the motor M1, the rotation of the motor M1 is transmitted to the hollow rotary shaft 16 via the gear 28 and the gear 20, and thus the extraction container 2 is rotated by the motor M1. .

As shown in FIG. 3D, the separator 19 is composed of, for example, a fixed plate 30, a filter 31, an elastic plate 32, and a pressing plate 33. The filter 31 is for separating the new raw material and the extraction residue from which the beverage has already been extracted once in the extraction container 2, and an elastic plate formed slightly larger than the fixed plate 30 and the pressing plate 33. 32 is for scratching the inner surface of the extraction container 2 with the extraction residue,
Due to the elasticity of the material, it slides in close contact with the inner surface of the extraction container 2.

Since the fixed plate 30 and the pressing plate 33 are dimensioned so that a gap is opened between the fixed plate 30 and the pressing plate 33, only the peripheral edge of the elastic plate 32 is in close contact with the inner surface of the extraction container 2. There is.

As the material of the elastic plate 32, for example, a material such as silicone rubber that has heat resistance and is harmless to food hygiene is used. Further, as the material of the fixing plate 30 and the pressing plate 33, a material having heat resistance and harmless in food hygiene, and having hardness enough to firmly hold the filter 31 and the elastic plate 32 is used. To form.

As shown in FIG. 4 (a), the funnel 3 is formed to have a structure in which the bottom surface is inclined, and collects the beverage separated when the cake is extracted by the filter 15 of the extraction container 2 and then to the FIG. 4 (b). The beverage is supplied to the cup 5 (FIG. 2) through the hole 34 shown in FIG.

Further, as shown in FIG. 5, a filter 35 is attached to the bottom of the extraction and discard box 4, and further, as shown in FIG. 6, a top plate 36 to which the extracted and discard box 4 is fixed is attached. Since a plate material such as punching metal that can be drained is used, the water content of the extraction residue discarded in the box 4 passes through the filter 35 and the top plate 36 and the water pan 37.
Are either collected and evaporated or discarded during cleaning.

Therefore, the extracted residues collected in the box 4 will not be moldy and will not rot and will be sanitary.

First, the configuration and operation of the entire beverage supply device according to the present invention will be described.

FIG. 6 is a front external view of the beverage supply device. The beverage supply device is composed of the beverage extraction device 1, a raw material supply device 41, and a hot water supply device 51.

The raw material supply device 41 is a device that sends the required amount of the raw material of the beverage to be extracted to the beverage extraction device 1, and the hopper 42.
The raw material stored in the crushing unit 4 is crushed in the crushing unit 43, and the crushing unit 4 is crushed by the centrifugal force of a rotary blade (not shown) of the crushing unit 43.
Through the guide cylinder 6 fixed to 3, the finely pulverized raw material is supplied to the brewing container 2 of the beverage brewing apparatus 1 in a constant required amount.

The reason for crushing the raw material before extraction is to improve the extraction efficiency, save the amount of raw material used, and shorten the extraction time.However, when using a raw material that has already been powdered, such as matcha. Does not require the crushing mechanism of the crushing unit 43,
A propeller or the like is used instead of the rotary blade because only centrifugal force is required to send the raw material through the guide tube 6.

Since the amount of the raw material supplied from the raw material supply device 41 is proportional to the operating time of the motor 44, by keeping the operating time of the motor 44 constant, a constant amount of the raw material can be delivered.

The hot water supply device 51 is a device that sends hot water necessary for extracting a beverage from the raw material supplied from the raw material supply device 41 to the extraction container 2 of the beverage extraction device 1 to the extraction container 2 of the beverage extraction device 1. .

The main tank 52 incorporates a heater 53 and a temperature controller 54, and always stores the boiled hot water at a constant temperature. The hot water of the main tank 52 flows into a sub tank 56 having a constant capacity, which is attached to the lower portion of the main tank 52 via a tube 55. Due to the principle of the balanced siphon, when the water levels of the tubes 57 connected to the main tank 52 and the sub tank 56 coincide with each other at the level h in FIG. 6, the hot water stops flowing into the sub tank 56, and Fill up. When the sub tank 56 is filled with hot water, the compressed air supplier 60 connected to the sub tank 56 via the tube 57, the joint 58, and the tube 59 is operated to send compressed air into the sub tank 56, The hot water is sent to the brewing container 2 of the beverage brewing apparatus 1 through the tube 61, the joint 62, and the tube 7.

As shown in FIG. 6, the sub tank 56 is mounted so that its upper surface is lower than the bottom surface of the main tank 52. Therefore, as long as the main tank 52 has hot water, the sub tank 56 must be filled with hot water. There is.

FIG. 7 is a sectional view of the sub tank 56, and the sub tank 56 is composed of a sub tank main body 63 and a lid 64. An O-ring 65 is attached to the sub-tank body 63 so as to face the lid 64, and the airtightness is maintained by tightening the lid 64.

As shown in FIG. 7, the sub tank 56 includes a check valve 66. When the hot water in the main tank 52 flows into the sub tank 56, the ball 67 is pushed by the water pressure and floats up, so that the check valve 66 is released.

In the diameter direction of the stopper 68 screwed into the check valve 66,
Since the strip-shaped stopper 69 is attached, the pole 67 does not jump out into the sub tank main body 63. Further, when the compressed air supplier 60 operates and compressed air flows into the sub tank 56, the ball 67 is pressed against the mortar-shaped valve seat 70 of the check valve 66, so the check valve 66 is closed. Therefore, the hot water in the sub tank 56 does not flow back to the main tank 52.

The on-off valve 71 (FIG. 6) is closed so that the air pressure does not decrease during the operation of the compressed air supply device 60, and is opened at other times. This is because the sub tank 56 is exhausted when the hot water in the main tank 52 flows into the sub tank 56, and therefore the sub tank 56 must be released to the atmospheric pressure.

The amount of hot water supplied to the extraction container 2 through the tube 7 is
Since it is proportional to the operating time of the compressed air supplier 60, by keeping the operating time of the compressed air supplier 60 constant, a constant amount of hot water can be constantly supplied to the brewing container 2 of the beverage supply device 1. If you want to change the amount of hot water according to the amount of beverage the user needs, for example,
It is also possible to supply an arbitrary amount of hot water by changing the operating time of the compressed air supply device 60 in several stages.

The heater 72 is for keeping the hot water in the sub tank 56 warm.

Next, the extraction operation of the beverage extraction device 1, which is a feature of the present invention, will be described.

As described above, the extraction container 2 is rotated by the motor M1 and the separator 19 is rotated by the motor M2.
In order to perform the extraction operation, which is a feature of the present invention, first, the forward / reverse rotation and rotation positioning of these two motors M1 and M2 are required.

Although various methods are conceivable for performing normal rotation / reverse rotation of the motors M1 and M2, an embodiment using an AC reversible motor will be described here. Although there are various methods for rotational positioning, an embodiment using a cam and a micro switch will be described here.

FIG. 8 is a connection diagram when the motors M1 and M2 are AC reversible motors.

When the switch S1 connected to one end of the AC power source is turned on to the M _IR (or M _2R ) side, the rotating shaft 2 of the motor M1 is rotated.
9 (or the rotation shaft 24 of the motor M2) rotates to the right, and when the switch S2 is turned to the M _1L (or M _2L ) side, the rotation shaft 29 of the motor M1 (or the motor M2).
The rotary shaft 24) rotates in the left direction.

By rotating the switch S1, the rotation directions of the separator 19 and the extraction container 2 can be controlled.

FIG. 9 and FIG. 10 are diagrams showing a beverage extraction operation by the extraction container 2 and the separator 19 of the beverage extraction device 1 according to the embodiment of the present invention, and FIG. 9 is the first first extraction. Operation, FIG. 10 shows the second and subsequent extraction operations.

First, the first extraction operation will be described with reference to FIG.

In FIG. 9, a certain amount of hot water is supplied from the hot water supply device 51 to the empty extraction container 2. Cam 22 and micro switch 8 at this time
