It is being The brewing device described in this publication has a heat retention function that is necessary to keep the beverage warm when producing a hot beverage. A heat shielding mechanism is provided to prevent the pot placed on the pot from being heated. This mechanism is a movable pedestal mounted on the pedestal to which the above-mentioned heating section is attached, and by raising the pedestal, the pot is separated from the heating section and heat-insulated. , the pot is placed on the heating section by lowering the pedestal.

[Problem to be solved by the invention]

By the way, when getting a cold drink,
Since ice is used to cool the extracted liquid, an extractor equipped with a pot and a filter device placed above the pot can be hot or cold whether or not ice is stored inside. It is formed at a height where there is no problem in extracting the beverage. Therefore, the above-mentioned extractor is designed to be high in consideration of the storage space for ice, and accordingly, water heaters equipped with a vessel body having an upwardly protruding portion located above the extractor are There were problems in that the height was also high and the entire extraction device was large.

An object of the present invention is to obtain a compact brewing device for brewing coffee, etc., which is not only capable of brewing hot beverages and cold beverages, but also has a small overall height.

[Means to solve the problem]

In order to achieve the above object, an apparatus for extracting coffee, etc. according to the present invention comprises: an extractor formed with a bottle and a filter device disposed above the extractor; a container; and a container that is movable up and down. a discharge pipe cover attached to and protruding from the upper surface of the vessel body;
It has a heating mechanism built into the vessel body to form hot water, and a discharge pipe connected at one end to the outlet of the heating mechanism and housed in the discharge pipe cover at the other end. a water heater comprising a discharge piping system in which the height position of a discharge port facing the filter device is adjustable; and a water heater formed at the lower part of the water heater, on which the bottle is removably placed; A mounting table capable of keeping the bottle warm; and a heat shield movably provided with respect to the mounting table between a heat transfer position that allows heat conduction from the mounting table to the bottle and a heat shield position that blocks the heat conduction. It is equipped with means.

[Effect]

According to the present invention, by moving the heat shielding means to the heat transfer position and placing the extractor that does not store ice on the mounting table, heat can be conducted from the mounting table to the bottle of the extractor, and the above-mentioned By supplying hot water to the extractor with a water heater, hot coffee or the like can be extracted into the bottle, and the extracted coffee liquid or the like can be kept warm by heat conduction heating from the mounting table. In addition, by moving the heat shielding means to the heat shielding position, the heat conduction between the mounting table and the bottle placed above it is blocked, and then the water heater is connected to the extractor containing ice. By supplying hot water, hot coffee liquid etc. extracted by a filter device can be cooled with ice to make a cold beverage. and,
At that time, the cold beverage in the bottle will not be heated due to heat conduction from the mounting table. In this way, hot or cold beverages, depending on the user's selection, can be automatically brewed without any hassle. In addition, when brewing a cold beverage as described above, the discharge pipe and discharge pipe cover are pulled upward from the water heater body to raise the height of the discharge port. Even if the overall height of the extractor increases due to storage, there is no need to increase the height of the container body in accordance with the height. Therefore, the height of the container can be determined based on the case where a hot beverage is obtained without storing ice in the extractor, so the height of the extractor and the container can be made smaller. It can be used as an extraction device.

To obtain hot coffee, etc., first lower the discharge pipe cover 36 as shown in FIG.
The heat shield table 3 is housed in the recess 44, and the extractor 2 for hot beverages in which the material to be extracted B is housed together with the paper filter A is placed on the cover plate 20 of the mounting table 16. Next, the water heater 19 of the mounting table 16 may be energized. Then, each time the water in the heating tube 18 is heated and boiled by the heat generated by the heater 19, the boiling pressure causes a heater pump action in which hot water is discharged to the discharge piping system 30. Therefore, each time hot water is discharged from the discharge port 35 little by little, the hot water is
It is poured into the material B to be extracted while being diffused by the water, and coffee, etc., is extracted. Then, the extracted hot coffee or the like passes through the extraction hole 8 and is stored in the bottle 4. The hot coffee or the like thus obtained is heated and kept warm by heat conduction from the table 16 having the kettle heater 19.

Moreover, to obtain cold coffee etc., it is done as shown in FIG. In other words, first, discharge pipe cover 3
6 is pulled up to protrude from the upper surface of the container body 15, and the position of the discharge port 35 of the discharge pipe 34 is raised. This adjustment is performed by the flexible deformation of the tube 33 in the discharge piping system 30.
This can be done without damaging the cover 36, and the raised state of the cover 36 is fixed by the engagement between the leaf spring 39 and the articulation projection 40. At the same time, the heat shielding table 3 is pulled out from the recess 44 and moved onto the mounting table 16. After this, the cold beverage extractor 2 is placed on the heat shield stand 3. Of course, there is ice C in the cooling container 6 used for this extractor 2.
Needless to say, it is stored there. In addition,
The distance F between the cold beverage extractor 2 and the discharge port 35 in this set state and the distance G between the extractor 2 and the discharge port 35 during hot beverage extraction shown in FIG. By adjusting the height position of the discharge port 35, the sizes are approximately equal. Next, the water heater 19 may be energized to cause the heater pump action described above. Then, hot coffee or the like extracted with hot water by the filter device 5 is cooled by ice C while passing through the cooling container 6, flows down from the water hole 14, and is stored in the bottle 4. In this case, the heat from the water heater 19 on the mounting table 16 is transferred to the heat shielding table 3.
, the cold coffee, etc. in the bottle 4 is prevented from being heated.

In addition, in explaining the second embodiment shown in FIGS. 4 and 5, the same structural parts as those in the first embodiment will be given the same reference numerals and explanations will be omitted, and only the different structural parts will be explained. do.

That is, in the second embodiment, the engagement groove 45 and the engagement protrusion 46 in the first embodiment are deleted, and the heat shield table 3 is configured to be moved in conjunction with the height adjustment of the discharge port 35. The other points are the same as the first embodiment described above. In order to perform the above-mentioned interlocking, for example, the heat shield stand 3 and the discharge pipe cover 36 are connected by an interlocking mechanism 51. Interlocking mechanism 51

Then, a second device having such an interlocking mechanism 51
According to the embodiment, the switching operation before brewing a hot beverage and a cold beverage becomes extremely easy.

Note that each of the above embodiments has a structure in which the heat shield stand 3 is pivotally attached to the container body 15, but in the present invention, the heat shield table 3 can be attached to and removed from the mounting table 16 of the container body 15. Therefore, it may be configured to be movably provided on the mounting table 16.

Furthermore, in the present invention, the mounting table 16 is configured to have only a heat-retaining heater, and the water heater 19
A heating mechanism such as a heater pump having a heating mechanism may be provided at a location other than the mounting table 16 described above.

Furthermore, the water heater 1 may supply hot water using a method other than a heater pump.

In addition, the structure that allows the height position of the discharge port 35 to be adjusted is such that instead of omitting the tube 33, the upper side of the connecting pipe 32 has a straight pipe structure with the upper end open, and this straight pipe part and the discharge pipe 34 The discharge piping system 30 may be configured to expand and contract by fitting the straight pipe portion with an open lower end so as to be slidable in the vertical direction via a water sealing member such as an O-ring. .

Moreover, in the present invention, the heat shielding table 3 may have a slatted shape or a perforated shape, and a switch that energizes the heat retaining heater provided on the mounting table 16 is opened and closed in conjunction with the movement of the heat shielding table 3. When the heat shielding table 3 is used, it may be configured to cut off the power supply to the heat-retaining heater included in the mounting table 16.

Further, the heat shielding means may be any type as long as it allows or blocks heat conduction from the mounting table to the bottle by moving with respect to the mounting table, and is not limited to the mounting table of the above embodiment.

In addition, in carrying out the present invention, unless it is contrary to the gist of the present invention, specific structures, shapes, etc. of water heaters, discharge piping systems, discharge ports, bottles, filter devices, mounting tables, heat shield tables, etc. It goes without saying that the position, material, etc. are not limited to the above embodiments, and can be implemented in various configurations.

〔Effect of the invention〕

Since the present invention described above has the configuration described in the claims above, it is possible to automatically extract a hot beverage and a cold beverage, and when extracting a cold beverage, the cold beverage in the bottle is heated. Of course, this can be prevented by heat shielding means, and the discharge port of the discharge piping system is positioned downward when brewing hot beverages, and the discharge pipe and its cover are pulled upward when brewing cold beverages. Because the discharge port is located at a high position,
There is no need to form the vessel body to match the height of the ejection port at this high position as a reference, and the height of the vessel body can be reduced, which has the effect of providing a compact extraction device.
