Description

[Detailed description of the invention] [Technical field of the invention] The present invention is a coffee extraction method that allows selectively obtaining sufficiently hot coffee liquid (so-called hot coffee) and coffee liquid cooled with ice (so-called iced coffee). Concerning vessels.

[Technical background of the invention]

In this type of coffee brewer, a thermal bottle is placed on a heating table that is heated by an electric heater that generates hot water, and the coffee liquid stored in the thermal bottle is heated and kept warm to produce hot coffee. Therefore, when making iced coffee, it is necessary to separate the thermal bottle from the heating table, so conventionally, as shown in Publication of Utility Model Publication No. 56-36436, the thermal bottle was placed on the heating table. The structure is such that a special mechanism is provided to lift and hold the heating table, or the heating table is slid laterally and housed in the container.

[Problems with background technology]

However, in any of the above configurations, not only does the configuration become complicated and lead to increased costs, but also space is required in the container to move the thermal bottle up and down and to slide the heating table, and the container is used exclusively for hot coffee. It had the disadvantage of being larger than the original. By the way, when producing iced coffee, ice is stored directly in a heat insulating bottle, or a liquid-permeable ice container is housed in the heat insulating bottle and ice is stored in the ice container. . However, in the former case, when pouring iced coffee from a thermos bottle into another cup, etc., the ice floating inside the thermos bottle flows out together with it, and when it falls into the iced coffee in the cup, it bounces back onto the iced coffee. However, in the latter case, the ice container containing ice is removed from the thermal bottle when pouring, so there is no problem with the above-mentioned rebound, but the problem is that the table etc. on which the ice cube is placed gets wet and dirty. When removed, drops from the ice container drip onto the table, floor, etc., staining the table, etc., as in the former case.

[Purpose of invention]

Therefore, the purpose of the present invention is to make it possible to produce iced coffee, to simplify the configuration and reduce costs, to make the container smaller, and to make it possible to make iced coffee easily when pouring the coffee liquid. To provide a coffee brewer that can prevent staining tables, floors, etc.

[Summary of the idea]

In this invention, inside the thermal bottle placed on the heating table,
By removably housing the inner bottle that collects the coffee liquid with a gap between it and the inner bottom surface of the heat-insulating bottle, the heat from the heating table is transferred to the inner bottle through the gap when producing iced coffee. The first feature is that the lid member attached to the inner bottle is provided with an ice stopper part that prevents the ice stored in the inner bottle from flowing out when pouring the coffee liquid in the inner bottle. The second feature lies in the fact that it is provided.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings. First, in Fig. 1, reference numeral 1 denotes a coffee extractor body with a grinder, and a motor storage chamber 2 is provided in the center lower part of this container, and a case mounting part 3 is formed in the upper part of this motor storage chamber 2. . Reference numeral 4 denotes a vertical shaft type motor disposed within the motor storage chamber 2, and a rotating shaft 4a of this motor projects above the upper case mounting portion 3.

A filter 8 and a cutter 9 are provided at the bottom of the case body 6, and the cutter 9 is connected to the motor 4.
It is removably connected to the rotating shaft 4a of. The receiver 7 is formed in the shape of a container with a bottom slightly inclined downward in one direction (to the right in the figure), and furthermore, an extraction port 7a is formed at the bottom thereof protruding to the right side of the motor storage chamber 2. has been done. Reference numeral 10 denotes a hot water diffuser shaped like a shallow container that is removably fitted into the upper opening of the case 5, and a plurality of hot water pouring holes 10 are provided at the bottom of this body.
a is formed. On the other hand, 11 is a cartridge type water storage tank installed on the left side of the vessel 1;
2 is a case 5, especially an extraction port 7 at the lower right side of the vessel body 1.
A heating table is provided below a, and an electric heater 13 and a heating tube 14 are buried in this in parallel. One end of the heating pipe 14 is connected to the water storage tank 11, and the other end is connected to a connecting pipe 15.
The hot water supply spout body 16 is connected to the upper part of the case 5 so as to be able to rotate in the horizontal direction. Reference numeral 17 denotes a heat-retaining bottle placed on the heating table 12, and is provided with a spout 17a and a handle 17b, which are positioned opposite to each other in the radial direction. Reference numeral 18 denotes a cylindrical container-shaped inner bottle having a spout 18a, which has a flange 18b (see FIG. 2) formed on the outer periphery of the upper end and a step 1 formed on the inner periphery of the upper end of the heat-retaining bottle 17.
7c, it is removably housed in the heat-insulating bottle 17, and in this accommodated state, a gap 19 is formed between the outer bottom surface of the inner bottle 18 and the inner bottom surface of the heat-insulating bottle 17. Additionally, in this embodiment, a gap 20 is also formed between the outer circumferential side of the inner bottle 18 and the inner circumferential side of the heat-retaining bottle 17. Reference numeral 21 denotes a lid member attached to the inner bottle 18 and the heat-retaining bottle 17, and a liquid passage part 22 is formed in a notch shape on one side (the left side in the figure) of the lid member. A tongue-shaped ice stopper portion 23 is provided in an inclined shape downward to the left in the figure. Then,
In the set state as shown in FIG.
The liquid passage part 22 is located on the spout 18a side of the inner bottle 18 and directly below the extraction port 7a, and the ice stopper part 2
3 is close to the inner peripheral surface of the inner bottle 18.

Next, the operation of the above configuration will be explained. First, when producing so-called iced coffee, water and coffee beans are stored in advance in the water storage tank 11 and the case 5 according to the number of people desired, respectively, and ice is stored in the inner bottle 18 to create the state shown in FIG. 1. Set it to . Then, energize the motor 4 and cut the cutter 9.
is rotated to crush coffee beans. After crushing,
When the electric heater 13 is energized to generate heat, the water in the heating pipe 14 supplied from the water storage tank 11 boils, and the boiling pressure causes the hot water to rise and reach the spout body 1.
6 and is sequentially supplied into the case 5 via the hot water diffuser 10. The hot water thus supplied into the case 5 passes through the coffee powder and the filter 8, and is extracted as coffee liquid from the extraction port 7a. This coffee liquid flows down onto the ice stopper 23 in the liquid passage part 22, drips into the inner bottle 18 from the gap between the ice stopper 23 and the inner bottle 18, and comes into contact with the ice there. At the same time as it is cooled, it is diluted with the molten water and stored in the inner bottle 18. When producing such iced coffee, the electric heater 13
As a result, the heating table 12 is heated and the thermal bottle 17 placed on it is also heated, but since the inner bottle 18 in which the iced coffee is stored is spaced apart from the inner bottom surface of the thermal bottle 17 by a gap 19. , this gap 19 exhibits a heat insulating effect and the heating table 12
The heat is prevented from being transmitted to the inner bottle 18 via the heat-insulating bottle 17, and the iced coffee in the inner bottle 18 is not heated. Furthermore, in this embodiment, since a gap 20 is also provided between the outer circumferential side of the inner bottle 18 and the inner circumferential side of the thermal bottle 17, the heat of the thermal bottle 17 heated by the heating table 12 is transferred to the inner bottle. 18 can be prevented more reliably. After this, when the thermal bottle 17 is taken out from the heating stand 12 and poured into a desired cup a (see FIG. 3), the ice b floating in the inner bottle 18 is prevented from flowing out by the ice stopper 23. Only iced coffee is poured into the cup a from the spout 18a. Therefore, unlike the conventional case where the ice flows out together with the iced coffee, the iced coffee in the cup A does not bounce back, and there is no need to stain the table etc. on which the cup A is placed. .

Next, we will discuss the case of producing so-called hot coffee. In this case, after removing the inner bottle 18 from the heat-retaining bottle 17, the heat-retaining bottle 17 is placed on the heating table 12, and the same operation as described above is carried out. When this is done, the coffee liquid flowing out from the extraction port 7a is collected in the heat insulating bottle 17. At this time, the entire heating table 12 is also heated by the heat generated by the electric heater 13, so that the coffee liquid is heated, thereby producing sufficiently hot hot coffee without cooling the coffee liquid.

Note that the present invention is not limited to the embodiments described above and shown in the drawings; for example, the ice stopper portion may have slits, small holes, meshes, etc. formed in the portion of the lid member 21 that corresponds to the extraction port 7a. Various modifications can be made without departing from the scope of the invention, such as allowing the coffee liquid to flow down from the extraction port 7a but preventing the ice from flowing out.

[Effect of idea]

As is clear from the above description, the present invention has an inner bottle that is removably housed inside the heat-insulating bottle with a gap between the bottle and the inner bottom surface of the heat-insulating bottle, in addition to the conventional structure exclusively for hot coffee. Because iced coffee or hot coffee can be produced by simply installing a heating bottle, there is no need to provide a lifting mechanism for lifting and holding a heat-insulating bottle or a sliding mechanism for a heating table, which simplifies the configuration and reduces costs. can be made smaller. Furthermore, since the lid member attached to the inner bottle is provided with an ice stopper that prevents the ice stored in the inner bottle from flowing out when pouring the coffee liquid in the inner bottle, it is possible to prevent the ice from flowing out when pouring the coffee liquid. This has the excellent effect of preventing coffee liquid from splashing back and contaminating the coffee cup from dripping.
