Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a portable coffee brewer mainly used in ordinary households to automatically extract coffee, black tea, green tea, etc.

[Conventional technology]

The conventional portable coffee brewer was first introduced in 1974.
As shown in Publication No. 142173, a water supply tank is attached to the rear of the extractor body containing a built-in water heater, and a bottle holder is provided at the lower front side of the extractor body to protrude forward. A coffee bottle is removably placed thereon, and a filter device is arranged on the bottle, with most of the coffee bottle being exposed.

This coffee extractor supplies hot water with a water heater, extracts coffee liquid with a filter device, and receives the extracted coffee liquid with a coffee bottle placed outside the extractor body. ing.

[The problem that the idea attempts to solve]

Conventional portable coffee extractors have a structure in which the coffee bottle and filter device are exposed outside the extractor body, which makes them unsightly and attracts dust during extraction and storage. It was unsanitary. In addition, there is a risk that the exposed coffee bottle may be damaged by other objects hitting it during storage or the like. Moreover, since the coffee bottle, etc. is simply placed on the bottle holder, if you handle it roughly when carrying the entire extractor, the coffee bottle, etc. may fall and break. This required careful attention. Further, since the coffee bottle is exposed directly to the outside air, the coffee liquid stored inside the bottle is likely to cool down due to heat radiation to the outside, resulting in poor heat retention.

[Means to solve the problem]

In addition to solving the above-mentioned conventional problems, the present invention has an opening at the front and an opening at the back to allow the power cord to be stored while preventing it from becoming too large. A box-shaped vessel is formed by connecting a narrow inner box and an outer box that covers the outer surface of the inner box except for the front edge of the inner box, and the box-shaped vessel has its front opening closed. A door-type opening/closing lid that can be opened and closed freely, a vertical water supply tank located outside the inner box and provided in the box-shaped body, and a storage space that the inner box has inside. a coffee bottle stored in the lower part of the storage space so as to be freely put in and taken out through the front opening and disposed below the filter device; In the space provided between the inner box and the outer box, in the upper space located above the storage space, there is a hot water supply port arranged facing the storage space, and in the space, the storage A heating plate disposed in the lower space located below the empty space, a heater and a water boiling pipe attached to the heating plate, and a heating plate provided in the space by connecting the hot water supply port and the water boiling pipe. a hot water supply device having a hot water supply pipe, boiling water supplied from the water supply tank and supplying the water to the filter device;
Outside the inner box and at the far side corner of the box-shaped container body, there is a code entrance and exit provided in the outer box, which is partitioned into the space, and the box-shaped container body is opened through this entrance. It is equipped with a cord storage part in which a power cord that is taken in and taken out from the outside is stored vertically.

[Effect]

The portable coffee brewer of the present invention stores the filter device and the coffee bottle in the storage space of the box-shaped container, and extracts and stores the coffee bottle with the opening/closing lid closed. It can be covered with a box-shaped body and an opening/closing lid. For this reason, it not only looks good, but also prevents dust from adhering to the coffee bottle and the like during brewing and storage.

Since the box-shaped container body and the opening/closing lid can protect the coffee bottle or the like in the storage space, it is possible to prevent other objects from hitting the coffee bottle or the like during storage or the like.

Furthermore, the box-shaped container body and opening/closing lid prevent coffee bottles from falling out of the storage space when being carried around, making it possible to handle them somewhat roughly, and preventing coffee bottles from falling off and falling out. You can carry the entire box-shaped container without holding it down with your hands.

Furthermore, when the power cord is not in use, it can be stored from the outside of the box-shaped container into the cord storage portion formed in the box-shaped container through the cord opening in the outer box, so that the power cord can be easily disposed of. The box-shaped vessel body is equipped with an inner box that has a storage space on the inside that becomes narrower toward the rear end. Although a dead space is inevitably provided, since this space is used to form the cord storage section, it is possible to prevent the box-shaped container body from increasing in size in order to provide the cord storage section.

Moreover, the coffee bottle stored in the storage space is surrounded by the box-shaped body and the opening/closing lid, and is not exposed to the outside air. In addition, not only is the storage space double-covered by the box-shaped container body consisting of an inner box and an outer box, but the space between the inner and outer boxes is equipped with a hot water supply system with a heater placed at the bottom of this space. Because the device is installed, when coffee liquid is extracted, the heat released to the outside by the heater of the hot water supply device located at the bottom of the space is trapped in the space, and the entire storage space is filled with heat. You can keep warm from the outside. Therefore, even when the heater is turned off, the heat retention of the coffee liquid stored in the coffee bottle can be maintained.

Further, reference numeral 58 denotes a steam exhaust section that communicates with the storage space 2 and is provided at the rear of the box-shaped vessel body 1.

Next, the case of extracting coffee liquid will be explained.
The user first fills the water tank 16 with water, then opens the lid 51 and takes out the coffee bottle 46 and the filter device 29 from the storage space 2 in the order listed. Then, the paper filter 32 is set in the filter cup 30 of the filter device 29, and after storing the ground coffee beans in the paper filter 32, the filter cup lid 31 is covered. Next, the filter device 29 is inserted through the front opening of the box-shaped container body 1 and stored in the upper part of the storage space 2. This storage is performed by sliding the rail engaging portion 34 of the filter device 29 onto the guide rail 7 of the storage space 2 and inserting it rearward. By this operation, the filter device 29 is engaged with and supported by the pair of guide rails 7, and its hot water diffusion portion 38 is disposed directly below the hot water supply port 23 to face each other.

Thereafter, the coffee bottle 46 is inserted through the front opening of the box-shaped container 1, stored in the lower part of the storage space 2, and placed on the heat retaining plate 26. As the bottle 46 is stored, the operation protrusion lever 42 of the drip prevention valve 41 and the bottle lid 49 engage, so that the valve lever 42 of the valve 41 is rotated around the shaft 43 against the force of the spring 45. When rotated, the valve body 44 opens the drip hole 35 of the filter cup 30.

Then, after closing the opening/closing lid 51, the power switch 56 is turned on. Then, the heater 19 of the water heater 17 generates heat, so the water is supplied from the water tank 16 into the water heater pipe 21 through the water inlet receiver 14, a check valve (not shown), and a water supply member.
6 is boiled in the water boiling pipe 21. The boiling pressure at this time closes the check valve, and hot water is ejected from the hot water supply port 23 through the hot water pipe 22 toward the hot water diffusion section 38 of the filter device 29. Since the internal pressure of the hot water supply device 17 disappears at the same time as this ejection, the water in the water supply tank 16 is supplied to the hot water pipe 21, and the so-called heater pump action as explained above is repeated again. This action is performed until water supply from the water supply tank 16 is completed.

By such hot water supply, coffee liquid is extracted in the filter cup 30, and the extracted coffee liquid is guided from the drip hole 35 to the liquid guide protrusion 36, passes through the socket hole 50 of the coffee bottle 46, and enters the container 47. stored inside. The coffee liquid stored in the coffee bottle 46 is kept warm by the heat insulating plate 26 to which part of the heat from the heater 19 is transmitted.

Moreover, the coffee bottle 46 in the storage space 2
is surrounded by the box-shaped vessel body 1 and the opening/closing lid 51 and is not exposed to the outside air. Moreover, since the entire storage space 2 is kept warm from the outside, the heat retention performance of the coffee liquid is good. That is, the storage space 2 is double covered with an inner box 3 and an outer box 5 that form the box-shaped vessel body 1, and the space between the inner and outer boxes 3 and 5 surrounding the storage space 2 is , since the hot water supply device 17 is disposed, when coffee liquid is extracted, the heat emitted from the heater 19 disposed at the lower part of the space to the surrounding area via the heating plate 18 is trapped in the space. Thus, the entire storage space 2 can be kept warm from the outside.
Therefore, even when the heater 19 is turned off, the heat retention of the coffee liquid stored in the coffee bottle 46 can be maintained.

A large amount of steam generated in the filter device 29 during the above extraction is quickly discharged from the filter cup 30 to the outside of the box-shaped container 1 through the steam discharge section 40, and the steam inside the storage space 2 is discharged from the steam discharge section. 58 etc., and is discharged to the outside of the box-shaped container body 1. Therefore, despite the provision of the opening/closing lid 51, it is possible to prevent steam from accumulating in the storage space 2 and condensing on the inner surface of the inner box 3 and objects stored in the storage space 2. .

The coffee extractor having the above structure is stored and housed with the filter device 29 and the coffee bottle 46 stored in the storage space 2 which is closed by the opening/closing lid 51. It is hygienic as it prevents dust etc. from adhering to the surface and making it dirty. In addition, since the box-shaped container body 1 and the opening/closing lid 51 can prevent other objects from hitting the filter device 29 and the coffee bottle 46 during storage and storage, it is possible to prevent the coffee bottle 46 and the like from being damaged by external damage. Further, when carrying, there is no need to hold the coffee bottle 46 or the like by hand, and it can be carried easily by grasping the handle 10 or the box-shaped container body 1. At this time, even if handled somewhat roughly, the box-shaped container body 1 and the opening/closing lid 51 can prevent the filter device 29 and the coffee bottle 46 from falling out of the storage space 2, thereby preventing the risk of damage due to falling. can.

Furthermore, the box-shaped container body 1 in the coffee extractor having the above configuration is provided with a cord storage section 12, and the bundled power cords 11 can be easily inserted into the cord storage section 12 through the cord opening 12c from the outside of the box-shaped container body 1. Since the power cord 11 can be stored in the box-shaped container 1, there is no need to wrap the power cord 11 around the box-shaped container 1 or bundle it and dispose of the cord while it is exposed outside the container 1. Therefore, it is possible to process the power cord 11 in a manner that is preferable for its maintenance and looks good.
The cord storage section 12 has a width that becomes narrower toward the inner end of the cord storage section 12, and is designed to avoid forming unnecessary gaps between the cord storage section 12 and the side wall of the outer box 5 of the box-shaped container body 1 as much as possible. an inner box 3 provided close to the side wall;
Since the cord storage part 12 is formed by using the dead space provided at one of the inner corner parts between the cord storage part 12 and the outer box 5, the cord storage part 12 can be provided without increasing the size of the box-shaped container body 1. I can do it. Moreover, in the structure of this embodiment, not only the cord storage section 12 is provided as described above, but also the box-shaped container body 1
Electrical components such as a power switch 57 are arranged in the side space of the box-shaped container 1, and a water tank 16 is arranged using the other rear corner of the box-shaped container 1. By disposing an opening/closing lid 51 on the front surface of the inner box 3, various parts are rationally arranged around the outside of the inner box 3. Therefore, the entire extractor can be configured into a compact box shape.

Although the above-mentioned embodiment is constructed as described above, in the present invention, the water supply tank 16 is connected to the box-shaped container body 1.
It may be formed integrally with the outer box 5. Furthermore, the filter device 29 does not use a disposable paper filter, but may be equipped with a removable or fixed filter, and
The filter cup lid 31 may be omitted. In addition, it goes without saying that the present invention can be implemented in various configurations as long as it does not go against the gist of the invention.

[Effect of idea]

According to the present invention, which has the configuration described in the above-mentioned utility model registration claim, a box-shaped container body provided with a water supply tank and a hot water supply device has a storage space inside the inner box. The filter device and the coffee bottle are stored in this storage space, and the front opening of the storage space is closed with an opening/closing lid to store the filter device and the coffee bottle and to extract coffee liquid. Therefore, it looks good during storage, prevents the filter device and coffee bottle from getting dirty with dust during storage and brewing, keeps them sanitary, and prevents damage to the coffee bottle due to external infections. Furthermore, since the box-shaped container and opening/closing lid allow the filter device and coffee bottle to be enclosed and carried together, there is no need to hold the coffee bottle with your hands to prevent it from falling out, making it easy to carry. can. Furthermore, the coffee bottle in the storage space is surrounded by the box-shaped container body and the opening/closing lid, so it is not exposed to the outside air, and the heat released from the water heater is transferred to the space between the inside and outside of the box-shaped container body. This heat can be used to insulate the storage space from the outside, improving the ability to keep coffee liquid warm. Moreover, since the inner box of the box-shaped vessel is narrower at the back end toward the rear end, there is an inevitable gap between the inner box and the outer box of the box-shaped vessel. By making use of the dead space provided in the box and forming a vertical cord storage section there, the power cord can be easily stored inside the box-shaped container. This has practical effects such as preventing the size of the container body from increasing.
