[Detailed description of the invention] [Industrial application field] This invention is an extraction machine used in coffee vending machines, etc., which extracts the ingredients by passing hot water through a raw material such as ground coffee beans powder and selling it. It is related to.

[Conventional technology]

Conventional coffee vending machines were first introduced in 1974.
As described in Publication No. 179799, the extractor that passes hot water through the raw material to extract the components in the raw material powder and discharges the extracted residue is located away from the water heater including the hot water storage tank, and the extraction machine is installed using a long hose. It is configured to supply hot water to the machine.

[Problem that the invention attempts to solve]

In conventional vending machines like the one mentioned above, the temperature of the water drops from the water storage tank to the extractor, so it is necessary to install a device that heats the water midway through the process, or to heat the necessary parts of the extractor. There was a problem in that an extra heating device such as an electric heater was required.

This idea solves the above problems,
The purpose of the present invention is to provide an extractor that uses the temperature of hot water in the hot water storage tank of a water heater to keep the extractor warm.

[Means for solving problems]

In order to achieve the above object, this invention includes a water heater having a raw material supply device and a hot water storage tank, and extracts components in the raw material by passing hot water supplied from the hot water storage tank into the raw material supplied from the raw material supply device, In this extractor, the bottom part of the extractor is fixed to the hot water storage tank of the water heater, in which the extractor is comprised of an extractor that automatically performs the operation of discharging the residue after extraction.

[Effect]

Since this invention has the above-mentioned configuration, hot water heated to a high temperature by the heater of the water heater is stored in the hot water storage tank. Then, in response to a dispensing signal, the hot water in the hot water storage tank is injected into the raw material being supplied to the extractor, thereby extracting components in the raw material and discharging them to the required parts.

In addition, since the bottom of the extractor is fixed on the hot water storage tank, the heat of the high-temperature hot water in the hot water storage tank is transmitted to the extractor via the bottom of the extractor, so the extractor is heated by a separate heating device. do not have to.

A plurality of (four in the figure) cylindrical chambers 8 are fixed to the rotating frame 7. The chambers 8 are open at their upper and lower ends, and are arranged at regular intervals on a circumference centered on the shaft 6.

As shown in FIGS. 2 and 4, an opening 10 with a filter 9 placed thereon and an opening 11 for discharging waste are formed near the front of the bottom plate 3, and a filter block 12 is fixed at the bottom of the opening 10. and its outlet 13
is provided with a gutter 14 that guides the extract to the required part, and the opening 1
A waste discharge tube 15 is provided at the bottom of the container 1.

Guide cylinders 16 and 17 directly above the openings 10 and 11 are respectively fixed to the upper part of the lid 5, and pistons 18 and 19 are fitted into the guide cylinders 16 and 17, respectively, and the lower ends of each guide cylinder 16 and 17 are fitted. The lid 5 is provided with openings into which pistons 18 and 19 fit.

Reference numeral 20 denotes a support frame fixed to the side of the guide cylinder 16 on the main body 2, and one end of the swinging body 21 is attached to this frame 20 by a shaft 22. A piston rod 2 connected to the piston 18 is inserted into the hole in the middle of the rocking body 21.
The upper end of the oscillator 21 is loosely fitted into the piston rod 23, and both ends of the push spring 24 fitted into the piston rod 23 push the oscillating body 21 and the piston 18, and the upper end of the oscillator 21 is supported by the large-diameter head 25 at the upper end of the piston rod 23. Further, the upper end of the piston rod 26 connected to the upper part of the piston 19 is connected to the tip of the rocking body 21, so that the piston 19 is moved up and down by the rocking of the rocking body 21.

Reference numeral 30 denotes a hot water supply pipe fixed to the side of the guide cylinder 16 and connected to the upper part of the hot water storage tank 1 mentioned above. A hot water introduction pipe 31 is also provided inside the piston 18.
The outer end of this pipe 31 communicates with the hot water supply pipe 30 when the piston 18 is in a fixed position, and the inner end of the introduction pipe 31 is open to the lower end of the piston 18.

Reference numeral 32 denotes a raw material supply device installed at the upper part of the rear portion of the main body 2, which supplies a fixed amount of powdered raw material, such as ground coffee beans, from the raw material supply port 33 (Fig. 2) provided in the lid 5 into the chamber 8 directly below it. supply to.

The rotating shaft 6, the swinging body 21, and the raw material supply device 32 are intermittently driven in the operating order described later by a drive mechanism such as a gear, a cam, and a link that is activated by a dispensing signal.

In the above configuration, a fixed amount of raw material discharged from the raw material supply device 32 by the discharge signal is supplied to the supply port 33.
After being put into the waiting chamber 8,
The rotating frame 7 rotates 90 degrees in the direction of the arrow in FIG. 2, and the chamber 8 containing the raw material comes onto the filter 9 and stops.

Then, as the rocking body 21 begins to rotate downward, the piston rods 23 and 26 descend, and the pistons 18 and 19 at their lower ends fit into the chamber 8 directly below them, respectively.

Immediately after the piston 18 starts to descend, the hot water supply pipe 30 on its side coincides with the outer end of the introduction pipe 31 inside the piston 18. At this time, the water supply pump (not shown) is activated, so the hot water inside the tank 1 is is pushed out,
The hot water flows through the hot water supply pipe 30 and the introduction pipe 31, and is ejected into the chamber 8 from the lower end opening of the piston 18, and then flows through the filter 9.
The components in the raw material are extracted by passing through the upper raw material, and the extracted liquid flows out from the outlet 13 to the gutter 14 and is injected into a cup or the like in a predetermined part.

Then, under the condition that the rocking body 21 rotates upward and the lower end of each piston 18, 19 does not touch the upper end of the chamber 8, the driving device of the rotating frame 7 operates to move the rotating frame 7 to the second position. Turn it an additional 90 degrees in the direction of the arrow in the figure.

For this reason, since the chamber 8 containing the squeezed dregs after extraction of the components on the filter 9 moves above the opening 11 and stops, most of the squeezed dregs in the chamber 8 fall from the opening 11 into the scum discharge tube 15.

Then, the rocking body 21 rotates downward again, and the pistons 18 and 19 enter the respective chambers 8 directly below them again, but the stroke of the piston 19 is so long that it reaches the opening 11 at the lower end of the chamber 8.

Therefore, all the squeeze dregs adhering to the inner surface of the chamber 8 in which the piston 19 is housed are also scraped off.

After the extraction is completed and the waste has been discharged, the chamber 8 is moved to the raw material supply port 3 by the intermittent rotation of the rotating frame 7.
3, and is in a state of waiting for the next payout signal.

Although the above action has been described with respect to one chamber 8, in reality there are a plurality of chambers 8 as shown in the figure, and the same action is performed in each chamber 8 in sequence.

That is, after the extraction of the raw material in the chamber 8 on the filter 9 is finished, each part is stopped until the next dispensing signal is output with each piston 18, 19 raised, but when the next dispensing signal is input, The raw material is supplied into the chamber 8 from the raw material supply port 33, and then the rotating frame 7 rotates 90 degrees. In the downward stroke, the components of the raw material on the filter 9 are extracted and the chamber 8 on the opening 11 is extracted.
At the same time, scraping of internal debris is done.

The mechanism of the embodiment includes a plurality of chambers 8 as described above.
While the rotating frame 7 having a rotary frame 7 rotates one pitch intermittently and stops, raw materials are simultaneously supplied, components are extracted, and squeezed waste is discharged in each chamber 8, and these parts are completely sealed. However, in this invention, the structure and operation of the extractor are not limited to those in the embodiment.

[Effect of idea]

This idea consists of a water heater that has a raw material supply device and a hot water storage tank as described above, and the raw material supplied from the raw material supply device is passed through hot water supplied from the hot water storage tank to extract the components in the raw material, and the extracted components are In this extractor, the bottom of the extractor is fixed onto the hot water storage tank of the water heater, so that the high temperature heat in the hot water storage tank is transferred to the bottom of the extractor. There is no need to heat the extractor with a separate heating device.

Furthermore, since the water heater and the extractor can be connected through a short hot water supply pipe, there is almost no drop in the temperature of the hot water. Therefore, there is less possibility that the hot water supply temperature will change due to a change in outside temperature. In addition, the parts that come into contact with products such as raw powders and extracts can be kept at a high temperature (usually above 63°C), which prevents the growth of bacteria and is hygienic.
