Abstract

PURPOSE:To collect used filters and coffee grounds which are sent after the extraction of coffee liquid by sorting and to effectively utilize containers by housing the filters and coffee grounds in respective waste containers uniformly. CONSTITUTION:This device is provided with a guide 55 for guiding a filter 51, which is sent out forward nearly in parallel after the extraction of coffee liquid and sent downward by a supporting roller 52a, backward obliquely downward at a proper length. Besides, the device is installed with a waste container 6A for coffee grounds 8 under an inflection point where the filter 51 changes its direction backward and a waste container 6B for filter under the terminal part 55a of the guide 55. When a filter 51 is sent downward, a part of coffee grounds 8 sent out on the filter 51 falls in the waste container 6A located just under to be collected and remaining coffee grounds falls in the waste container 6A to be collected while losing support when the filter 51 is further sent backward. On the other hand, the filter 51 lowers by gravity at the terminal part 55a of the guide 55 to be housed in the waste container 6B located just under.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention is for preparing fresh brew coffee in a cup type vending machine or the like.
The present invention relates to a coffee extractor for extracting coffee liquid from a liquid mixture of powdery coffee raw material and warm water.

[0002]

2. Description of the Related Art As a coffee extractor of this type installed in a vending machine, one shown in FIG. 6 is known. In the figure, 1 stores regular coffee as a raw material for coffee,
A raw material box 2 for carrying out a predetermined amount of the coffee raw material in response to a sales signal is a hot water tank for opening a solenoid valve 21 in response to the sales signal to supply a constant amount of hot water. The coffee extraction device is configured as follows. That is, 4 is a cylinder, which is provided with a piston 41 that slides up and down, and a liquid tray 42 that is movably supported up and down. 5 is a filter mechanism, which is a roll 51a
Band-shaped paper filter 51 wound around
A support roller 52a for supporting the filter, a feed roller 52b rotated by a motor to press both end portions of the filter 51 against the support roller 52a, and a pair of guide rollers 52c, and a pair of guide rollers 52c. Is fed at a constant length between the cylinder 4 and the liquid tray. 6 is a garbage container.

In the coffee extractor, the piston 41 is in the upper limit position and the liquid tray 42 is in contact with the lower surface of the cylinder 4 with the filter 51 interposed therebetween in the standby state for sale. The raw material of coffee from the raw material box 1 according to the sales signal is the chute 1
Hot water from the hot water tank 2 is supplied into the cylinder 4 via the hot water supply pipe 1 and into the cylinder 4 via the hot water supply pipe 22. A mixed liquid of hot water and a coffee raw material swollen by the hot water is produced in the cylinder, and the mixed liquid is pressurized by the piston 41 which descends and filtered by the filter 51, and the coffee liquid is extracted into the liquid receiving tray 42. This coffee liquid is sent to a mixing bowl (not shown) through a pipe 43, sugar, cream and the like are added and stirred to prepare a coffee drink. After the extraction of the coffee liquid, the liquid receiving tray 42 descends, the feed roller 52a rotates, and the used filter 51 with the raw material residue 8 left on the upper surface is fed toward the waste container 6. The waste container 6 contains the used filter 51 and the raw material residue 8 together. Reference numeral 61 is a cover that is detachably fixed to a support member provided in the main body case of the vending machine, and prevents the raw material residue sent into the waste container 6 from scattering to the outer door side.

[0004]

By the way, in the coffee extractor, the used filter 51 and the raw material residue 8 are discarded together, but recently, it is said that the separation treatment of refuse is noisy. It is desired to be able to separate and collect. Further, in a cup-type vending machine, the front surface of the waste container 6 is close to the inner surface of the outer door of the vending machine, and it is difficult to receive the filter 51 sent out to the center of the waste container 6. In this case, as shown in FIG. As shown in the drawing, the filter 51 is accommodated on the front side of the waste container 6 in a biased manner, and there is a problem that the filter 51 overflows forward while leaving a sufficient space in the container.

An object of the present invention is to provide a coffee extractor capable of separately collecting a used filter and a raw material residue and properly collecting them in a container.

[0006]

In order to achieve the above object, according to the present invention, a mixture of powdery granular coffee raw material and hot water is filtered by a band-shaped filter fed by a constant length and the coffee is heated. In a coffee extraction device that extracts a liquid and puts the raw material residue after extraction on a filter and stores it in a dust container, with a guide that sends the filter sent out after extraction in a substantially opposite direction, and in the opposite direction. A raw material waste container is disposed below the curved portion, and a filter waste container is disposed below the end portion of the guide.

[0007]

By feeding the used filter in the opposite direction on the way, the raw material residue is naturally dropped at the curved portion in the opposite direction and separated from the filter. Since the filter descends from the end portion of the guide located above the filter waste container, the filter is accommodated in the waste container without being biased and the waste container is effectively used for recovery.

[0008]

1 to 3 show a first embodiment of the present invention, in which parts common or identical to those in FIG. 6 are designated by the same reference numerals. 1 to 3, reference numeral 55 denotes a pair of left and right guides which are fixed to a guide 61 supported by a support member of the main body case and which respectively guide the left and right side end portions of the used filter 51. It extends obliquely downward, and its rear end forms a terminal portion 55a for guiding the filter. The trash container is formed by being divided into a trash container 6A for raw material residue and a trash container 6B for filters. The trash container 6A is installed with the lower part of the front end of the outer periphery of the support roller 52a substantially in the center, and the trash container 6B is provided with a guide 55. It is installed with the lower end of the end portion 55a substantially in the center.

In the above structure, the feed roller 52b places the raw material residue 8 on the liquid receiving tray 42 and feeds it substantially horizontally to the front, and passes through the support roller 52a and descends downward. The sheet is bent to be in contact with the sheet, is curved, is guided by the guide 55, and is fed obliquely rearward and downward.
Then, it descends from the end portion 55a of the guide 55 and is stored in the dust container 6B. In this case, the end portion 55a is the waste container 6
Since the filter 55 is located above the center of B, the filter 55 is sequentially packed from the bottom of the waste container 6B and is stored in the waste container 6B. On the other hand, part of the raw material dregs 8 sent on the filter 51 drops when the filter 51 passes the support roller 52a and is sent downward, and the remaining residue at this time is also turned backward by the guide 55. Fall without losing support. Thus, the raw material residue 8 is entirely stored in the dust container 6A arranged immediately below the drop. Therefore, the used filter 51 and the raw material dregs 8 are separated and collected, and they do not overflow to the outside without filling the dust container.

FIGS. 4 and 5 show a second embodiment of the present invention. The difference from the above-mentioned embodiment is that a guide 55 is used.
This is the point where a vibration exciter 57 for applying vibration to the cover is attached to the cover 61. The shaker 57 may be, for example, one in which an eccentric weight is attached to the motor shaft and the cover 61 is vibrated by the eccentric rotation of the weight due to the rotation of the motor shaft. In this embodiment, the used paper filter 51 is used.
Is sent, the vibrator 57 is energized and the guide 5
The vibration of 5 vibrates the filter 51 guided by the guide 55. Due to the vibration of the filter 51, the raw material dregs 8 containing water and strongly attached to the filter 51 are also shaken off and fall into the dust container 6A. Therefore, also in this embodiment, the same effect as that of the above-described embodiment can be obtained, and the advantage that the separation with the raw material filter is performed more severely can be obtained.

[0011]

According to the present invention, a mixture of powdery and granular raw material of coffee and hot water is filtered by a band-shaped filter fed at a constant length to extract the raw liquid of coffee, and the raw material residue after extraction is removed. In a coffee extractor that puts it on a filter and stores it in a waste container, a guide for sending the filter sent out after extraction in a substantially opposite direction is provided, and a waste container for raw material residue is provided below the curved portion in the opposite direction. In addition, since the filter waste containers are arranged below the end of the guide, the used filter and bean dust are collected separately and the waste is separated, and at the same time, the filter and the raw dust are removed. And are stored in each waste container without any bias, and the waste container is effectively used.
