Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is a coffee machine that is equipped with a Mi/L/machine #4 and that produces coffee liquid by supplying hot water from a hot water generation mechanism to ground coffee powder. Regarding manufacturing machines.

[Technical background of the invention]

Conventionally, in order to produce a rich and delicious coffee liquid, the entire coffee powder is first swollen with hot water, then the coffee powder is steamed immediately to make it easier to extract the coffee extract, and then hot water is reheated to extract the coffee liquid. It is known that doing so is good. Conventional coffee makers with such a steaming function control the supply and stop of hot water by turning on and off the entire timer of the electric heater and the hot water generating mechanism, and when the brewing starts, the coffee is heated first. The system is configured to temporarily supply hot water to the coffee powder to steam the coffee powder, and then continuously supply hot water to extract the coffee liquid.

In addition, in a coffee making machine equipped with a full mill iso structure, in order to take the case in and out from the opening on the top surface of the body, the case is connected to the upper end of the connecting pipe extended from the hot water supply Seigandou generation mechanism so as to be horizontally rotatable. When brewing coffee, the hot water supply pipe is placed in the upper case, and when the case is taken in and out, the hot water supply pipe is rotated outward so that it does not get in the way. 5 [Problems with background technology] However, in order to produce even more delicious coffee liquid, it is necessary to supply hot water to the coffee grounds intermittently throughout the entire extraction period, not just at the beginning of extraction, and to steam the coffee grounds every time the hot water supply is stopped. It is better to extract the coffee liquid by using the same method, and considering this, conventional coffee making machines are still insufficient in terms of taste. However, if the intermittent N hot water throughout the entire extraction period as described above is performed by turning on and off the hot water generation mechanism using a timer, there is a problem that the configuration becomes extremely complicated and expensive. Ta. Therefore, in order to be able to provide intermittent hot water supply throughout the entire extraction period without complicating the configuration, hot water is supplied to a single hot water storage tank, and a siphon phenomenon occurs each time a predetermined amount of hot water is stored in this hot water storage tank. It is conceivable to configure the system so that hot water is supplied to coffee grounds. However, if you do this, the hot water storage tank must be placed above the tank, which will get in the way when you put the case in and take it out, and you will have to take it on and off each time you put the case in and take it out, making operation cumbersome. This produces M between the upper parts.

[Purpose of the invention]

Therefore, an object of the present invention is to make it possible to intermittently supply hot water to coffee grounds throughout the entire brewing period with an extremely simple configuration by utilizing the siphon phenomenon, and to also enable the attachment and detachment of the hot water storage tank independently of the opening and closing of the shade. There is no need to provide an excellent coffee making a't.

[Summary of the invention]

The present invention provides a hot water storage tank for storing hot water supplied from a hot water generation mechanism in a tray whose upper opening can be fully opened and closed, and a siphon that supplies the hot water in the hot water storage tank to the coffee grounds in the case by siphoning. By providing a 411 line, whenever a predetermined amount of hot water is drawn into the hot water storage tank, it is passed through the siphon mechanism (intermittently throughout the entire period of coffee brewing, so that it is supplied to the coffee grounds). In addition to making it possible to supply hot water, the hot water storage tank is also rotated upward as the shell is opened so that the dust case can be taken out and cleaned.

Further, the cylinder 31 is formed in a cylindrical shape with a closed upper surface, and a plurality of inlets 31ai are intermittently formed at the lower end thereof. Reference numeral 55 denotes a hole that communicates the inside of the hot water storage tank 25 with the atmosphere.In addition, in the Honto example, the hot water supply pipe 26 is connected to the hot water storage tank 25r (for the inflow amount of hot water supplied per unit time from the Mat mouth body 30). 64 is a switch that selectively energizes the drive motor 11 and the sheathed heater 15; it is not shown in the figure, or when the shu 22 is opened, it becomes Geo 7. A sheathed heater 15 of this switch 34 is provided.
-j switch, tray switch, and tray are connected in series to the sheath heater 150 in the energizing path.

Next, the operation of the above configuration will be explained. Coffee Association 1 When manufacturing an IC, first the water storage tank 5 and case, '
Pour water and coffee beans into 1lill varnish 6, respectively, and pour case 6.
Place the diffuser 17 on top and cover the tray 221.
'□Then, the valve body 62 of the refill port body 60 connects to the diffuser 17.
is pushed up by the upper end of the convex portion 18 to open the outlet end 30a. Thereafter, the switch 34 is operated to energize the cutting motor 11 to rotate the cutter 12 and crush the coffee beans. Next, by operating the switch 34, the drive motor 1
1 is turned off, and the sheathed heater 15 is energized to generate heat, thereby preheating the cup 9. At the same time, the water supplied from the water storage tank 5 into the heating pipe 16 is heated to generate hot water. This heat #h rises in the ha pipe 26 due to boiling pressure and flows into the hot water storage tank 25. The hot water flowing into the hot water storage tank 25 gradually rises as shown in FIG. 5 and enters the gap between the cylindrical body 61 and the hot water supply opening 30, and the hot water level rises as shown in FIG. When the strength exceeds the upper net of the cylinder body 61, the siphon mechanism 29 causes a siphon phenomenon and the hot water is discharged from the outlet end 30a of the hot water supply spout body 60 to the hot water receiving part 19 of the expanding body 17 as shown by arrow A. .

Then, the hot water discharged into the hot water pan 19 drips from the first pouring hole 20 of the hot water pan 19, is diffused from the skin 19a to the surrounding area, and drips from the second pouring hole 21 to the case 6. It penetrates evenly into the entire coffee powder inside. When the hot water stored in the hot water storage tank 25 causes a siphon phenomenon and begins to flow out, the situation inside the hot water storage tank 25 gradually deteriorates, and as shown in FIG.
When the temperature drops to the upper end of 1a, air is sucked into the siphon i side 29 and stops flowing out from the hot water supply port body 3o. When this happens, the hot water storage tank 25 (c)
Hot water is not supplied to the coffee grounds until the hot water level rises to cover the upper end of the cylindrical body 31, so during this hot water supply stop, the coffee grounds are passed through the V strainer and supplied as described above, and the hot water is sufficiently When the hot water in the hot water storage tank 25 increases and is supplied to the coffee powder by the siphon mechanism 29, the coffee powder is sufficiently steamed. A rich coffee liquid is extracted from the extraction port 8a.
It flows out and is stored in the cup 9. After that, the supply of hot water is stopped and supplied six times, and each time the supply is stopped, the coffee powder is steamed and the extract is easily extracted, and then hot water is supplied and the coffee liquid is extracted. This is repeated until a desired amount of coffee liquid is stored in the cup 9. After producing the coffee liquid in this way, when the lid 22't is opened to clean the case 6, the hot water supply pipe 26 and the hot water storage tank 25 are rotated upward and separated from the top of the case 6, so that the case 6tJl is immediately opened.
You can take it out and clean it.

Note that even if the lid 22t is opened by mistake during the extraction of coffee liquid, the lid switch (not shown) turns off the electricity to the sheathed heater 5 and the valve body 62 closes to the convex portion 1.
Since the hot water supply spout body 30 is closed at a distance from the hot water supply spout body 8, hot water will not be discharged from the hot water supply spout body 50.

In this way, according to this embodiment, the entire coffee extraction period t
Since heat #kt can be intermittently supplied to the coffee powder, the coffee powder 1' during the -1 stop.

Steam it thoroughly and remove its extract. ::, 11. The process of creating a state where coffee can be easily extracted, then supplying boiling water to extract the coffee liquid is repeated several times, making it possible to extract all of the richer and more delicious coffee liquid. Moreover,
It has a very simple configuration in which hot water from the hot water generation mechanism 13 is stored in the -H hot water storage tank 25, and when the stored amount reaches a predetermined amount, it is supplied to the case 6 by the siphon effect of the Tsuhiki siphon mechanism 29. Since it can supply hot water completely, there are no moving parts, and the structure is simple and can be manufactured at low cost. Furthermore, when a certain amount of hot water is stored in the hot water storage tank 25, a siphon phenomenon occurs and the hot water is supplied to the leakage case 6, so the amount of hot water supplied per time is approximately constant at 1E, and the timer stops the hot water supply. Unlike in the case of a configuration in which hot water is supplied intermittently by using the electric heater tm@ of the generating device, there is no inconvenience in that the amount of water supplied per time is greatly reduced depending on the water temperature. In addition, when case 6 is divided by #, when the demand 22 is opened, the hot water storage tank 25
is rotated upward: 1.

Since it leaves the upper part of case 6, case 6 is immediately removed.

It is easy to use as it can be taken out and cleaned once.

〔Effect of the invention〕
1. As is clear from the above description, the present invention
In the coffee making machine with 11, a hot water storage tank is installed in the straw, and a siphon mechanism is installed to supply hot water to the case each time a predetermined amount of hot water is stored inside the tank. It is possible to intermittently supply hot water to the coffee powder throughout the entire period, and it is possible to extract a richer and more delicious coffee liquid.Moreover, such intermittent supply #h can be done by using a siphon mechanism, without using a timer or the like. Since the process is carried out by utilizing the phenomenon, it is possible to provide a coffee making alt which has a simple structure and can reduce costs, and also has the effect that the case can be taken out immediately after opening the straw and is excellent in operability.
