Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a siphon type beverage making machine.

[Technical Background of the Invention] Coffee making machines are conventionally known as this type of siphon type beverage making machine. FIG. 6 shows the conventional siphon-type coffee making machine. In the figure, reference numeral 1 denotes a base body forming a handle portion 2, and a holder 3 is provided on the handle portion 2. Further, 4 is a lower container, and 5 is an upper container having a water pipe 6 and a filter 7. Coffee powder obtained by separately grinding coffee beans with a coffee mill or the like is placed in the upper container 5, while the lower container 4 is By pouring an appropriate amount of water in accordance with the amount of coffee powder and connecting the upper container 5 while inserting the water pipe 6 into the lower container 4, the upper container 5 flows through the water pipe 6 and the filter 7 into the lower container 4. Then, they are held in the holder 3 by the narrowed opening of the lower container 4. In this state, a heater 8 consisting of an alcohol lamp or an electric heater is placed below the lower container 4 to generate heat and heat the water in the lower container 4. Then, the water in the lower container 4 will eventually boil, generate steam, and gradually increase its steam pressure, and when it reaches a pressure above the window, the hot water in the lower container 4 will flow through the water pipe 6 due to the steam pressure. It is then fried into the upper container 5 through the filter 7 and mixed with coffee powder to form coffee liquid. Thereafter, when the heater 8 stops generating heat, the lower container 4 cools down and the internal vapor pressure drops, creating a vacuum effect, which causes the coffee liquid in the upper container 5 to flow through the filter 7 and It is led into the lower container 4 through the water pipe 6. Thereafter, the upper container 5 is removed from the lower container 4, the handle portion 2 of the base 1 is held, the lower container 4 is tilted together with the base 1, and the coffee liquid is transferred to the coffee cup.

[Problems with the Background Art] In the case of the above-mentioned conventional method, it takes a considerable amount of time from the time coffee grounds are put into the upper container 5 until the water in the lower container 4 is boiled and the hot water is further fried into the upper container 5. It takes a while,
Meanwhile, the coffee powder in the upper container 5 remains unattended.
As a result, the unique aroma of coffee is dissipated and lost, resulting in a problem that a delicious coffee liquid cannot be obtained. Furthermore, the coffee grounds left in the upper container 5 are exposed to the steam rising from the lower container 4 until the hot water is fried, and as a result, they become moist and degassing from the coffee particles becomes difficult. The problem is that it is not done well and makes the taste of the coffee liquid even worse.

[Objective of the Invention] The present invention has been made in view of the above-mentioned circumstances, and therefore, its object is to reliably obtain a delicious coffee liquid without losing the unique aroma of coffee and with good degassing. Our goal is to provide you with an excellent beverage making machine.

[Summary of the Invention] The present invention provides a lower container that can store water heated by a heater, an upper container that communicates with the lower container through a water pipe and a filter, and a pulverized raw material such as coffee beans that is supplied into the upper container. By providing a mill mechanism to heat the hot water from the lower container, and by providing a temperature-sensitive element that senses the temperature of the water in the lower container and activates the mill mechanism when it reaches a predetermined temperature, the water can be heated immediately before the hot water is fried from the lower container. The feature is that coffee powder can be supplied into the upper container.

[Embodiment of the Invention] An embodiment in which the present invention is applied to a coffee making machine will be described below with reference to FIGS. 1 to 5.

First, in FIG. 2, reference numeral 11 denotes a base body, which comprises a rectangular box-shaped base 12 having an appropriate height and a platform part 13 protruding from the lower end of the base to one side. The base part 13
As shown in FIG. 1, a heater 14 consisting of an electric heater mainly made of, for example, sheathed wire or nichrome wire is installed. A lower container 15 is removably placed on the heater 14, and is made of, for example, a heat-resistant glass container, and a handle 16 is attached to the tapered opening of the upper portion. On the other hand, 17 is an upper container, which is also made of, for example, a heat-resistant glass container, from which a water pipe 18 extends from approximately the center of the bottom.
A filter 19 is installed inside the base of the water pipe 18, and a gasket 20 is installed on the outside.The water pipe 18 is inserted into the inside from the mouth of the lower container 15, and then inserted into the mouth of the lower container 15. By press-fitting the packing 20, the upper container 17 is joined to the lower container 15, and at the same time, they are communicated through the water pipe 18 and the filter 19. On the other hand, 21 is a mill mechanism provided above the base 12 of the base body 11, and a motor 2 located inside the base 12.
2, a case 23 located outside the base 12, and a crushing blade 25 located inside the case 23 and connected to the motor 22 via a separable shaft coupling 24,
Particularly, the case 23 has a coffee bean inlet 27 on its top surface that can be opened and closed by a lid 26, and a coffee powder outlet 28 on its side surface. A filter 29 having a mesh diameter smaller than that of the filter 19 is attached, and a coffee powder guide 30 is provided extending from the coffee powder discharge port 28, the tip of which reaches the upper part of the upper container 17 and opens downward. Reference numeral 31 denotes a hole formed in the lower part of the base 12 facing the lower container 15;
A support 32 is disposed inside. Reference numeral 33 denotes a temperature-sensitive response element slidably inserted through the hole 31, for example, at a temperature of about 90['C].
] It is a thermostat that closes at a temperature below -1- and remains open until then.
A spring 36 is interposed between the proximal end of the holder 34 on the opposite side and the rear wall of the support 32. Due to the spring force, the thermostat 33 moves the temperature sensing part 35 to the base 1.
2 and is brought into pressure contact with the side surface of the lower container 15. A switch 37 is located above the holder 34 and attached to the support 32. As will become clear later, it is a safety switch that responds to the loading and unloading of the lower container 15. Now that it is placed, the actuator 37a is pressed by the holder 34 and is in a closed state.

Next, in FIG. 4, 38 is a power switch, and
Reference numeral 39 denotes a time switch that operates in conjunction with the thermostat 33 and performs a timing operation only when the thermostat 33 is closed, and both are provided at appropriate locations on the base 12 of the base 11. On the other hand, 40 is a plug that is plugged into a power outlet (not shown), and is connected to the power switch 38. Said safety switch 37. The motor 22 of the mill mechanism 21 is connected through a thermostat 33 and a time switch 39 in this order, and the heater 14 is connected in parallel with the series circuit of the thermostat 33, time switch 39, and motor 22.

When using the device configured as described above, first plug the plug 40 into a power outlet (not shown) and connect it, and in this state, hold the handle 16 from above the heater 14 and lift the lower container 15 to the top. Then, the upper container 17 is removed from the lower container 15, and the required amount of water is poured into the lower container 15. After that,
The upper container 17 is attached to the lower container 15 again, and the lower field 'a15 to which the upper container 17 is attached is placed on the heater 14. On the other hand, remove the lid 26 from the case 23 of the mill mechanism 21 and put the raw material coffee beans inside the case 23.
Thereafter, the lid 26 is reattached.

After that, the time switch 39 is set to a time length that matches the amount of coffee beans, and then the power switch 38 is closed. At this time, the safety switch 37 is in the open state because the actuator 37a is pushed in through the thermostat 33 and its holder 34, which are pressed by the side surface of the lower container 15 as described above. 37, the heater 14 generates heat and heats the lower container 15, in other words, the water in the lower container 15. However, at the time when this heating is started, the temperature of the water in the lower container 15 is low, so the thermostat 33 is not yet closed and remains open.
Therefore, the motor 22 of the mill mechanism 21 remains de-energized. Further, at this time, the time switch 39 is also in a standby state without executing a timing operation because the thermostat 33 is not closed.

Under these circumstances, the water in the lower container 15 continues to be heated, and its temperature gradually rises to about 90['].
C] is reached. Then, the thermostat 33 senses the temperature and closes, and in conjunction with this, the time switch 39 starts timing operation, and the motor 22 is energized, and the energized motor 22 starts. .

When the motor 22 starts in this way, the shaft coupling 2
Grinding blades 25 connected via 4 are rotated within the case 23 to grind the coffee beans contained within the case 23. At the same time, the ground coffee beans, that is, coffee powder, are supplied into the upper container 17 through the coffee powder outlet 28 and the coffee powder guide 30 in order from those that have passed through the filter 29, and the supply is finished. At this point, the time switch 39 finishes its timekeeping operation and opens, so the motor 22 is cut off and the rotational drive of the crushing blades 25 is stopped. During this time, the lower container 1 is heated by the heater 14.
The water in the chamber 5 continues to be heated, and therefore, when the supply of the coffee powder is finished, it boils, generates a lot of steam, and rapidly increases its steam pressure, so that the steam pressure exceeds a certain level. There, the hot water in the lower container 15 passes through the water pipe 18 and the filter 19 to the upper container 1 due to its steam pressure.
The coffee powder is fried in a container 17, and mixed with the coffee powder in the container 17 to become liquid coffee. After this for a certain period of time (
For example, when the power switch 38 is opened after 2.3 [minutes], the heater 14 is cut off and stops generating heat.Based on this, the lower container 15 cools down and the vapor pressure inside it decreases, creating a vacuum. As a result, the coffee liquid in the upper container 17 passes through the filter 19 and the water pipe 18 to the lower container 1.
5 and is stored in the lower container 15. Therefore, after this, hold the handle 16 and take out the lower container 15 together with the upper container 17 from above the heater 14, then remove the upper container 17 from the lower container 15, hold the handle 16 again, tilt the lower container 15, and pour out the coffee liquid. All you have to do is transfer it to a coffee cup (not shown).

In this way, according to this embodiment, the case 2 of the mill mechanism 21
The coffee beans placed in the container 3 are heated and boiled in the water placed in the lower container 15, and the generated hot water can be partially ground and supplied to the upper container 17 immediately before being fried in the container 17. Therefore, in the conventional device, the coffee powder obtained by crushing coffee beans in advance is placed in the upper container and the hot water generated in the lower container is fried in the upper container. It does not dissipate the characteristic aroma of coffee, so it does not lose its aroma.
In addition, the coffee powder does not become moist and degassing is performed well, thus ensuring that delicious coffee liquid can be obtained. Moreover, in the case of this embodiment, a series of steps from heating the water in the lower container 15 to grinding the coffee beans and extracting the coffee liquid can be automatically performed, making it very convenient.

In particular, in the case of the above embodiment, the lower container 15 is connected to the heater 14.
If you take it out from the upper position, the thermostat 33
Since the compression of the thermostat 33 and the holder 34 is released, the thermostat 33 and the holder 34 are moved by the spring 36.
The actuator 3 of the safety switch 37 is pushed out by the spring force of
Release the push in 7a. Therefore, the safety switch 37 is opened and the power to the heater 14 and motor 22 is cut off, thereby preventing unexpected situations caused by mischief or careless operation, and providing excellent safety. be able to. However, this is not necessarily necessary, and therefore, the safety switch 37 and the above-described mechanism for operating it may be provided only if necessary.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but is particularly applicable as a whole to beverage-making machines other than coffee-making machines, such as those for producing black tea or green tea. Furthermore, the heater may be a heater other than an electric heater, such as an alcohol lamp, etc., and may be modified as appropriate without departing from the spirit of the invention.

[Effects of the Invention] As is clear from the description below, the beverage making machine of the present invention includes a lower container that can store water heated by a heater, and an upper container that communicates with this lower container through a water pipe and a filter. In addition, a mill mechanism for pulverizing raw materials such as coffee beans and supplying the raw materials into the upper container, and /I for the water in the lower container. a temperature-sensitive cord that senses the temperature and operates the mill mechanism when the temperature reaches a predetermined temperature;
As a result, coffee powder can be fed into the upper container just before hot water is heated from the lower container.
This has the excellent effect of not losing the unique aroma of coffee, allowing good degassing, and ensuring that a delicious coffee liquid can be obtained.
