Description

[Detailed explanation of the idea] [Purpose of invention] (Field of industrial use) The present invention relates to a siphon type beverage making machine.

(Prior Art) Coffee making machines are conventionally well known as this type of siphon type beverage making machine. FIG. 5 shows the conventional siphon type coffee making machine. The middle part 1 is a base body, which has a handle part 2 and a holding part 3 above it. On the other hand, 4 is a lower container, 5 is a water pipe 6 and a filter 7.
Coffee powder is put into the upper container 5, and an appropriate amount of water corresponding to the amount of coffee powder is put into the lower container 4, and then a water pipe 6 is inserted into the lower container 4. The upper container 5 is airtightly joined by inserting the lower container 4 into the holding portion 3 of the base 1, and the joined containers 4 and 5 are fitted into the holding portion 3 of the base body 1 at the narrowed mouth portion of the lower container 4 and held therein. In this state, a heating element 8 such as an electric heater or an alcohol lamp is placed below the lower container 4.
It generates heat and heats the water in the lower container 4.
Then, the water in the lower container 4 will eventually boil and generate steam, which will gradually increase its steam pressure.When the pressure reaches a certain level, the hot water in the lower container 4 will flow through the water pipes 6 and 4 due to the steam pressure. It is fried through a filter 7 into an upper container 5, where it is mixed with coffee powder to form coffee liquid.
After that, when the heating element 8 stops generating heat and further moves the heating element 8 away from the lower position of the lower container 4, the lower container 4 cools down, and the vapor pressure inside it decreases, causing a vacuum effect. Based on this, the coffee liquid in the upper container 5 is led into the lower container 4 through the filter 7 and 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 to be solved by the invention) In the case of the conventional device, as described above, the lower container 4 is supplied from the upper container 5 through the filter 7 and the water pipe 6.
When transferring the coffee liquid that has reached the inside into a coffee cup, the upper container 5 must be removed from the lower container 4 one by one, and the lower container 4 must be folded.
Since the water pipe 6 of the upper container 5 is deeply inserted inside, the upper container 5 must be lifted high until the water pipe 6 escapes from the inside of the lower container 4, which is very troublesome to handle. , furthermore, the folded upper container 5
The coffee liquid is often freshly transferred into the lower container 4 and is still quite hot, and holding the hot upper container 5 may cause burns to the hand, and furthermore, it is so hot that it is difficult to drop the upper container 5. This has caused problems such as damage caused by

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to simplify the handling of coffee liquid when transferring it to a coffee cup, and to avoid the risk of getting burnt when folding it.
In addition, there is no possibility of failures such as dropping and damaging the upper container, and furthermore, it is possible to absorb variations in the dimensions of each part over a wide range, ensuring a reliable setting state, and making the setting operation smoother. The purpose of the present invention is to provide an extremely practical beverage making machine that can perform the following tasks.

[Structure of the device] (Means for solving the problem) The present invention separates the water pipe from the upper container and provides it integrally with the lower container lid, and the lower container lid closes the opening at the upper end of the lower container. A water pipe is accommodated in the lower container, and the lower container is arranged so as to be removable below the upper container together with the lower container lid. When the upper container is placed below the upper container, the elastic part is contracted by the lower container lid, and the return force of the elastic part by the return means causes the elastic body to be in pressure contact with the lower container lid to communicate more closely.

(Function) According to the above means, when transferring coffee liquid, it is possible to transfer the coffee liquid by handling only the lower container without having to lift the upper container from the lower container to remove it. By expanding and contracting the expandable part, variations in dimensions of each part can be absorbed over a wide range, allowing for more reliable and smoother setting.

(Example) An example in which the present invention is applied to a coffee making machine will be described below with reference to FIGS. 1 to 4.

First, in FIG. 2, reference numeral 11 denotes a base body, which includes a rectangular box-shaped base portion 12 having an appropriate height, a holding portion 13 protruding from the upper and lower middle portions of the base portion to one side on the left side in the figure; It also has a base plate part 14 protruding from the lower end to one side. As shown in FIG. 1, the base part 14 has a heating element 15 built in, such as a sheathed wire or a nichrome wire, etc. A short cylindrical insertion port 16 whose diameter gradually decreases downward from the lowest central portion is provided, and an elastic body 17 is attached to the insertion port 16. Here, the elastic body 17 is specifically made of a heat-resistant elastic material such as silicone rubber, and has a pipe shape as a whole as shown in FIG. A portion 18 is formed. Moreover, the insertion port 6 of the holding part 13 is provided on the upper part of the elastic body 17.
An upper mounting part 19 is formed in which the diameter is gradually reduced in accordance with the shape of the holding part, and a lower mounting part 21 having a groove 20 around the entire circumference is formed in the lower part. It is tightly attached to the insertion port 16 of the portion 13 and, in turn, to the base body 11. Reference numeral 22 denotes a collar plate, which is attached to the lower mounting portion 21 of the elastic body 17 by fitting into the groove 20;
2, a guide cylinder 23 is provided to protrude downward from the area around the insertion opening 16 of the holding part 13, and the outer peripheral protrusion 24 of the collar plate 22 is opposed to the inner peripheral surface of the guide cylinder 23. There is. Reference numeral 25 denotes a stopper protruding from the lower end edge of the guide tube 23 to determine the lowering limit of the collar plate 22. A compression coil spring 26 is installed between the flange plate 22 and the insertion port 16 of the holding part 13, and this spring always urges the flange plate 22 downward, so that the elastic part 18 of the elastic body 17 The spring 26 provides a return force in the direction of extension when it is contracted. Therefore, in this embodiment, the spring 26
This serves as a means of returning to 8.

Referring again to FIG. 1, the upper container 27 is made of, for example, a transparent cylindrical heat-resistant glass container, and the entire upper surface and the center of the bottom surface are open. A short cylindrical portion 28 is extended downward from the elastic body 1.
By inserting the upper container 27 into the insertion port 16 of the holding portion 13 attached to the base member 11 from above, the upper container 27
We are trying to get the support of Reference numeral 29 denotes a filter, which is disposed within the upper container 27 so as to cover the opening of the bottom surface. On the other hand, numeral 30 denotes a lower container, which is also made of, for example, a transparent cylindrical heat-resistant glass container, and has an opening only at the center of the upper surface, that is, the upper end, and has an opening extending from the periphery of the opening toward the outer side ( A handle 31 is provided protruding from the left side in the figure. Reference numeral 32 denotes a lower container lid, which is made of heat-resistant plastic, for example, and a water pipe 33 having a length close to the depth of the lower container 30 is integrated in its center by, for example, integral molding. On the other hand, a gasket 35 is attached to the outer surface of the rib 34 on the outer periphery of the lower surface.

Now, in the case of the structure as described above, when producing coffee liquid, first, the upper container 2 is
The upper container 27 is supported by the base 11 by putting coffee powder, which is a raw material, into the container 7 and inserting the cylindrical part 28 into the insertion port 16 of the holding part 13 from above, or by The coffee powder is placed in the upper container 27.
On the other hand, the lower container 30 is filled with an appropriate amount of water that matches the amount of coffee powder, and then the lower container lid 32 is inserted into the upper opening by inserting the water pipe 33 into the upper opening. It is press-fitted through the packing 35 and installed airtight. And this lower container lid 3
The lower container 30 with 2 attached thereto is placed from the side on the base plate 14, in other words, on the electric heater 15 which is a heat generating element, and at the same time presses the flange plate 22 from below upwards and dives below it. Do it like this. Then, the spring 26 is compressed, and at the same time, the elastic part 18 of the elastic body 17 is contracted, allowing the lower container 30, together with the lower container lid 32, to sneak under the flange plate 22. The container 30 is smoothly placed and set under the upper container 27.
Further, in the set state, the elastic part 18 of the elastic body 17 which has contracted as described above exerts a restoring force in the extension direction due to the restoring force of the spring 26, and comes into pressure contact with the lower container lid 32. Therefore, the elastic body 17 and the water pipe 33 communicate closely, and the upper container 27 also closely communicates with the water pipe 33 via the elastic body 17. When the electric heater 15 is then energized to generate heat in such a state, the water in the lower container 30 is heated and eventually boils, generating steam and increasing its steam pressure. When the pressure reaches a certain level, hot water flows from the lower container 30 into the upper container 30 through the water pipe 33 and the filter 29 due to its steam pressure.
7, and the fried water is poured into the upper container 2.
In step 7, it mixes with the previous coffee powder to form coffee liquid. There, for a certain period of time (for example, 2 or 3 [minutes])
After that, when the electric heater 15 is turned off and its heat generation is stopped, the lower container 30 cools down and the vapor pressure inside it drops, creating a vacuum effect, which causes the coffee in the upper container 27 to cool down. The liquid passes through the filter 29 and water pipe 33 to the lower container 30.
and is stored in the lower container 30.

Here, as mentioned above, the coffee liquid is in the lower container 3.
0, the coffee liquid is then transferred to a coffee cup (not shown). At this time, in this embodiment, the lower container 30 is held horizontally by the handle 31. By pulling
The upper container 27 remains on the holding part 13 and the lower container 30
All you have to do is take it out. That is, in this embodiment, the operation of removing the upper container 27 from the position above the lower container 30 is no longer necessary, and
Since this folded water pipe 33 is separated from the upper container 27 and is integrally provided with the lower container lid 32, it is possible to lift the upper container 27 high until the water pipe 33 escapes from the inside of the lower container 30. Even the lower container 30 has its water pipe 33, which can be made unnecessary.
Since it is provided integrally with the lower container lid 32, it can be taken out together with it as desired as described above. And also, this folding upper container 27
Even if the coffee liquid is still hot after being transferred into the lower container 30, there is no need to hold it, thereby eliminating the risk of burns and furthermore, dropping the upper container 27 and damaging it. We can prevent such failures from occurring. Incidentally, as the lower container 30 is taken out from the lower position of the upper container 27, the elastic part 18 of the elastic body 17 lowers the collar plate 22 with the return force of the spring 26 and moves the stopper 22 downward.
5, and the state is shown in Fig. 4.

By the way, as mentioned above, the elastic body 17 having the elastic part 18 that expands and contracts as the lower container 30 is set and taken out is different from an elastic body such as a packing that does not have the elastic body 17, which expands and contracts as the lower container 30 is set and taken out. From the height or base part 14 of the base 11 to the holding part 13
Even if the height of contact with the lower container lid 32 varies due to variations in the dimensions of each part, such as the distance between the parts, the height of contact with the lower container lid 32 will be absorbed over a wide range by the expansion and contraction of the elastic part 18, and therefore the lower container lid 32 Therefore, a more reliable setting of the lower container 30 can be obtained, and high quality and excellent safety can be obtained without leakage of hot water or coffee liquid. Furthermore, the elastic part 18 of the elastic body 17 that expands and contracts as described above allows the lower container 30, together with the lower container lid 32, to enter and set the upper container 27 downward more smoothly. Therefore, the ease of handling can be further improved.

The restoring means for applying a restoring force to the stretchable part 18 of the elastic body 17 is not limited to the spring 26, and may be, for example, the elasticity of the stretchable part 18 itself. Further, although the flange plate 22 is effective in preventing buckling of the elastic body 17 in combination with the guide cylinder 23, it is not necessarily necessary.

In addition, the present invention can be similarly applied to other devices other than coffee making machines, such as those that make tea, and furthermore, the heating element exemplified as an electric heater can be applied to other devices other than the electric heater, such as an alcohol lamp, etc. The present invention may be modified and implemented as appropriate without departing from the gist of the present invention.

[Effects of the invention] As is clear from the above description, according to the invention, in a siphon-type beverage making machine, the water pipe is separated from the upper container and integrated with the lower container lid, and the The opening at the upper end of the lower container is closed with a container lid, and a water pipe is accommodated in the lower container, and the lower container is arranged so as to be removable below the upper container together with the lower container lid, and the lower container is placed in communication with the upper container. When the lower container is placed below the upper container, the elastic body provided on the base body is contracted by the lower container lid, and the elastic body is brought into pressure contact with the lower container lid by the return force of the return means of the elastic portion. Due to the structure in which the coffee liquid is transferred to the lower container, there is no need to lift the upper container higher than the lower container to remove it, and it is possible to transfer the coffee liquid by handling only the lower container, making it easy to handle. Moreover, there is no risk of getting burnt when folding, and there is no risk of failure such as dropping the upper container and damaging it, and in addition, the dimensions of each part are This has the effect of absorbing variations within a wide range and ensuring a reliable set state, as well as allowing the setting operation to be performed more smoothly.
