Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a vending machine configured to add boiling water to raw materials, filter the mixture with a filter, and take out an extract.

Prior Art This type of vending machine is constructed as shown in FIG. Water heated to about 93° C. in a hot water tank 1 is supplied to an extraction filter 3 via a solenoid valve 2, where it is mixed with coffee powder 4 and filtered. In the extraction filter 3, pressure filtration is performed using high pressure air 5 or the like in order to shorten the sales operation period. The extract extracted by the extraction filter 3 is sent to a mixing/stirring section 6, where cream 7, sugar 8, etc. are added and dispensed into a cup 9 which is dispensed at a position facing the product dispensing port. ing. The hot water supply route 10 from the hot water tank 1 to the extraction filter 3 includes a first
A heater 11 is provided to reheat the water and prevent the water temperature from dropping. Further, a second heater 13 is provided in the extract dispensing path 12 from the extraction filter 3 to the mixing/stirring section 6 to prevent the temperature of the coffee which is reheated and dispensed into the cup 9 from dropping.

Problems to be solved by the invention In such a conventional configuration, the first heater 11
The coffee is reheated in the cup 9 and efficiently extracted with hot water in the extraction filter 3, and is reheated in the second heater 13 so that the hot coffee can be dispensed into the cup 9. However, the first and second heaters 11,
The power supply connection to 13, the installation space, and the installation work are troublesome.

The purpose of the present invention is to provide an extraction filtration device that can efficiently extract hot products using an extraction filtration device and dispense hot products into cups, and that can easily connect the power supply to the heater and reduce the installation space.

Means for Solving the Problems The extraction filtration device of the present invention has a first pipe that forms part of the hot water supply route from the hot water tank to the extraction filter, and a part of the extraction liquid discharging route from the extraction filter. The second tube to be formed is placed close to each other, the first tube and the second tube are thermally coupled into a single block, and this block is heated by a single heater.

Effect According to this configuration, the first pipe forming part of the hot water supply route and the second pipe forming part of the extract discharging route from the extraction filter are brought close to each other, and the first pipe and The second tube can be thermally coupled to a single block, which can be heated by a single heater.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Components having the same functions as those in FIG. 3 showing the conventional example are given the same reference numerals and their explanations will be omitted.

FIG. 1 shows the extraction filtration device of the present invention. 14 is a block formed by casting a first pipe 15 forming a part of the hot water supply path 10 and a second pipe 16 forming a part of the extract discharging path 12 into aluminum, as shown in FIG. As shown, a heater 17 is attached to the side surface of the block 14, and the block 14 is heated by the heater 17. The hot water supply route 10 is
A first silicon tube 18a connecting the solenoid valve 2 and one end 15a of the first tube 15;
It is formed by a second silicon tube 18b connecting the other end 15b and the extraction filter 3. The extract dispensing path 12 includes a third silicon tube 18c that connects the extraction filter 3 and one end 16a of the second tube 16, and a third silicon tube 18c that connects the other end 16b of the second tube 16 and the mixing/stirring section 6. 4 silicon tubes 18.

With this configuration, simply by connecting the power supply to the heater 17, the hot water is reheated when passing through the first pipe 15, and the extract is reheated when passing through the second pipe 16. Moreover, since these reheatings can be performed through a single block, handling is easier than in the past.

Effects of the invention As described above, according to the invention, the first pipe forms part of the hot water supply route from the hot water tank to the extraction filter, and the second pipe forms part of the extract discharging route from the extraction filter. the first tube and the second tube are brought into close proximity to each other, the first tube and the second tube being thermally coupled into a single block;
Since this block is configured to be heated by a single heater, the hot water supplied from the first pipe and the extracted liquid from the second pipe can be reheated by simply attaching a single heater to the single block, making it possible to reheat the hot water supplied from the first pipe and the extracted liquid from the second pipe. Its handling becomes easier. It is possible to eliminate the troublesome work of power supply connection and installation work, which is required in the past, in which the hot water supply route and the extract dispensing route are heated by separate heaters, and the installation space can also be reduced.
