  Beverages such as coffee and tea can be obtained with better taste and aroma when extracted at as high a temperature as possible. Therefore, it is required that the temperature of the hot water supplied in the extraction unit is not lowered as much as possible.

  In the coffee dripper described in Patent Document 2, it has been studied to reduce the decrease in hot water temperature depending on the material of the coffee dripper, and the funnel-shaped main body is made of wood. However, if the coffee dripper is made of wood, the temperature drop during coffee extraction is suppressed to some extent, but the cost of the material itself is high and the processing requires time and cost, which is not suitable for mass production.

  Then, an object of this invention is to provide the drink extractor which can suppress the hot water temperature fall during the extraction of a drink with the structure suitable for mass production.

  The characteristic structure of the beverage extractor according to the present invention is a beverage extractor having an extractor for extracting a beverage using supplied hot water, wherein the extractor contains the beverage extraction raw material therein and It is formed between an inner dripper part to which hot water is supplied to the extraction raw material, an outer dripper part in which the inner dripper part is arranged on the upper side, and the inner dripper part and the outer dripper part, and stores air. And a heat insulating space that suppresses the outflow of heat from the inner dripper, and the heat insulating space is at least closed at the upper side in the vertical direction.

  According to this characteristic configuration, the heat insulation space formed between the inner dripper portion and the outer dripper portion suppresses the outflow of heat from the inner dripper portion, so the temperature of the hot water supplied to the inside of the inner dripper portion The decrease can be suppressed. In addition, since at least the upper side in the vertical direction of the heat insulation space is closed, the outflow from the heat insulation space is suppressed even if the temperature of the air stored in the heat insulation space rises and becomes lighter. Can keep warm. That is, since the material of the inner dripper part and the outer dripper part is not questioned, it is possible to suppress a decrease in hot water temperature during beverage extraction with a configuration suitable for mass production.

  The further characteristic configuration of the beverage extractor according to the present invention is that the inner dripper is made of metal.

  According to this characteristic configuration, since the inner dripper portion is made of metal, the heat capacity of the inner dripper portion is reduced. Then, the amount of heat transferred from the hot water to the inner dripper portion until the supplied hot water and the inner dripper portion reach substantially the same temperature is small. In other words, since the inner dripper part is quickly warmed by the supplied hot water and the outflow of heat from the inner dripper part is suppressed by the heat insulating space, it is possible to further suppress the decrease in hot water temperature during beverage extraction. In addition, the processing of the inner dripper is further facilitated, and the configuration is more suitable for mass production.

  A further characteristic configuration of the beverage extractor according to the present invention is that the inner dripper is formed of a material having a thickness of 0.4 mm to 0.6 mm.

  According to this characteristic configuration, since the inner dripper portion is formed of a material having a thickness of 0.4 mm or more and 0.6 mm or less, the heat capacity of the inner dripper portion is reduced as much as possible while ensuring workability. be able to. That is, it is possible to provide a beverage extractor that achieves both mass productivity and heat retention.

  A further characteristic configuration of the beverage extractor according to the present invention includes a dripper holder on which the inner dripper portion and the outer dripper portion are placed on the upper side, and the dripper holder can be opened and closed at an upper portion of the beverage extractor. It is at the point where it is placed.

  According to this characteristic configuration, the inner dripper portion and the outer dripper portion are placed on the upper side of the dripper holder, and the dripper holder is disposed so as to be opened and closed. Therefore, the inner dripper portion and the outer dripper portion from the beverage extractor Easy to put on and take off. In addition, if the dripper holder is configured to cover a part of the outer dripper part, it is possible to further increase the heat retaining property and further suppress the decrease in hot water temperature during beverage extraction.

  First, the space S3 (thermal insulation space) will be described. The inner dripper part 35 is disposed above the outer dripper part 33, and a space S3 (heat insulation space) is formed between the side surface part 33e of the outer dripper part 33 and the side part 35f of the inner dripper part 35. . In the XZ cross section shown in FIG. 4, the space S <b> 3 is thinly formed along the side surface portion 35 f of the inner dripper portion 35. The upper end (Z direction) of the space S3 in the XZ cross section is closed by the contact between the upper end of the side surface portion 35f and the upper end of the side surface portion 33e. The lower end (−Z direction) of the space S3 in the XZ cross section is open downward (−Z direction) and rearward (−X direction). Therefore, since the space S3 flows to the outside, the space S3 is filled with air.

The upper end (Z direction) of the space S3 in the YZ cross section is closed by the ring member 34. The lower (−Z direction) end of the space S3 in the XZ cross section is closed when the lower end of the side surface portion 35f and the bottom surface portion 35g of the inner dripper portion 35 are in contact with each other.

  As described above, since the inner dripper part 35 and the outer dripper part 33 have substantially the same shape, the space S3 is formed so as to surround the entire circumference of the side surface portion 35f of the inner dripper part 35. The space S3 is formed so as to surround most of the bottom surface portion 35g of the inner dripper portion 35. The space S3 is formed to cover at least 70% or more of the total area of the outer surface of the inner dripper portion 35, that is, the side surface portion 35f and the bottom surface portion 35g.

  Next, the space S4 will be described. An outer dripper portion 33 is disposed on the upper side of the dripper holder 30, and a space S <b> 4 is formed between the peripheral wall portion 30 b of the dripper holder 30 and the side surface portion 33 e of the outer dripper portion 33. In the XZ cross section shown in FIG. 4, the space S4 is thicker than the space S3 on the front side (+ X side) of the outer dripper 33, that is, the size in the X direction is larger than the space S3. On the rear side (−X side) of the outer dripper portion 33, the peripheral wall portion 30b and the side surface portion 33e are arranged far apart from each other because the peripheral wall portion 30b is formed vertically. That is, the volume of the space S4 is larger on the rear side (−X side) than on the front side (+ X side) in the X direction.

  In the YZ cross section shown in FIG. 5, the space S <b> 4 is formed thin along the side surface portion 33 e of the outer dripper portion 33. The lower end (−Z direction) of the space S4 in the YZ cross section is closed when the peripheral wall portion 30b and the side surface portion 33e come into contact with each other.

  As seen in FIGS. 3 and 4, the upper end (+ Z direction) of the space S4 is not closed because the peripheral wall portion 30b and the side surface portion 33e are separated on the upper side (+ Z direction) of the space S4. . That is, since the space S4 is in communication with the outside, the space S4 is filled with air. Thus, the space S4 functions as an outer heat insulating space that suppresses the outflow of heat from the outer dripper portion 33.

  In other words, the coffee maker E according to the present embodiment has the extraction unit 3 that extracts the beverage using the supplied hot water. It has the inner dripper part 35 supplied and the outer dripper part 33 by which the inner dripper part 35 is arrange | positioned above. The coffee maker E has a space S3 (heat insulating space) that is formed between the inner dripper portion 35 and the outer dripper portion 33, stores air, and suppresses the outflow of heat from the inner dripper portion 35. In S3, at least the upper side in the vertical direction is closed. Thereby, since the outflow of heat from the inner dripper part 35 is suppressed by the space S3 formed between the inner dripper part 35 and the outer dripper part 33, the temperature of the hot water supplied to the inside of the inner dripper part 35 The decrease can be suppressed. In addition, since at least the upper side in the vertical direction of the space S3 is closed, the outflow from the space S3 is suppressed even if the temperature of the air stored in the space S3 rises and becomes lighter. Can keep warm. That is, since the material of the inner dripper part 35 and the outer dripper part 33 is not ask | required, it becomes possible to suppress the hot water temperature fall during extraction of coffee C with the structure suitable for mass production. The upper side in the vertical direction of the space S3 only needs to be closed to such an extent that a decrease in hot water temperature inside the inner dripper portion 35 is suppressed to a certain extent so that coffee C with good quality (taste / fragrance) can be obtained. Airtightness is not required.

  Furthermore, in the coffee maker E according to the present embodiment, a space S4 (outer heat insulating space) is formed between the outer dripper portion 33 and the dripper holder 30 so that air is stored and the heat outflow from the outer dripper portion 33 is suppressed. Has been. Due to the synergistic effect of the space S3 (insulation space) and the space S4 (outer insulation space), it is possible to further suppress a decrease in hot water temperature during the extraction of the coffee C.
