Description

Coffee machine

Technical Field

The invention relates to a drip filter type coffee machine, in particular to a coffee machine with a large range of brewing cups.

Background

Conventionally, as such a coffee machine, the following coffee machine is known (for example, see patent document 1): the coffee machine comprises a housing (corresponding to the coffee machine main body of the invention), a glass container (corresponding to the container (server) of the invention), a filter chamber (corresponding to the filter cup mechanism of the invention) arranged on the glass container, and a water outlet pipe and a water purifying device (corresponding to the hot water injection mechanism of the invention) arranged on the housing, wherein hot water is injected into the filter chamber from the water outlet pipe through the water purifying device, so that coffee liquid is extracted from coffee powder in the filter chamber.

[ problems to be solved by the invention ]

However, in such coffee machines, particularly coffee machines having a large range of the number of brewed cups (e.g., 1 to 6 cups), the number of brewed cups may not be extracted well when they approach both ends of the extraction range. For example, in the coffee machine capable of brewing 1 to 6 cups as described above, the size of the filter cup mechanism needs to be large enough to brew 6 cups, and if such a filter cup mechanism is used, it may not be effective in brewing 1 cup. Conversely, if the size of the mechanism is reduced to accommodate a small number of cups, it becomes possible to put 6 cups of ground coffee in a small mechanism, and the effect may be poor when brewing 6 cups.

When coffee is brewed manually, a mechanism of a filter cup of different sizes is generally used depending on the number of brewing cups. Therefore, it is also conceivable to prepare a plurality of filter cups having different sizes for the coffee maker and select the filter cup to be used depending on the number of brewing cups. However, if a plurality of filter cups having different sizes are used separately in the coffee maker, the distance from the hot water injection mechanism of the coffee maker main body to the filter cup mechanism varies. Therefore, there is a possibility that the hot water cannot fall to an appropriate position of the coffee powder in the cup mechanism, or the temperature of the falling hot water is too high or too low, and thus the coffee liquid cannot be extracted optimally. In addition, when the coffee maker has a coffee grinder, the distance from the coffee maker main body to the filter cup mechanism becomes large, which may also cause the coffee powder to easily overflow out of the filter cup mechanism.

The invention aims to provide a coffee machine which can solve the problems and can extract coffee liquid optimally even if the number of brewing cups is different.

Detailed Description

A first embodiment of the present invention will be described below with reference to fig. 1 and 2. In the present embodiment, the upper and lower sides of each drawing are defined as the upper and lower sides of the actual case. 1 is the coffee machine of the present invention. The coffee maker 1 includes a coffee maker main body 2, a container 3, and a filter bowl mechanism 4.

The coffee maker main body 2 includes an upright portion 5, a base portion 6, and a brim portion 7. The container 3 is placed on the base 6. A hot water injection mechanism 8 is disposed below the brim 7. The vertical positional relationship between the hot water injection mechanism 8 and the brim 7 is fixed.

The container 3 has a container body 9 having a bottom and an open top, and a handle 10 provided on a side of the container body 9. In addition, the container body 9 may be a glass container or a stainless steel vacuum double container.

As the filter cup mechanism 4, as shown in FIG. 1, a first filter cup 11 for small cup number extraction (for example, for 1 to 3 cups of extraction) or a second filter cup 12 for large cup number extraction (for example, for 4 to 6 cups of extraction) is placed on the container body 9 of the container 3 as shown in FIG. 2. The first bowl 11 has an extraction part 13 formed in a tapered manner, a height adjustment part 14 provided below the extraction part 13, and a flange-like mounting part 15 provided below the height adjustment part 14. On the other hand, the second cup 12 has an extraction portion 16 formed so as to be tapered in the lower direction, and a flange-like placement portion 17 provided below the extraction portion 16. Further, the extraction part 13 of the first bowl 11 is formed smaller than the extraction part 16 of the second bowl 12. The height adjusting part 14 is sized such that the vertical distance from the upper end of the extracting part 13 of the first cup 11 to the lower end of the mounting part 15 is the same as the vertical distance from the upper end of the extracting part 16 of the second cup 12 to the lower end of the mounting part 17. That is, in a state of being placed on the container 3, the height of the upper end of the extraction part 13 of the first bowl 11 is equal to the height of the upper end of the extraction part 16 of the second bowl 12. Therefore, the vertical distance from the hot water injection mechanism 8 to the extraction section 13 of the first bowl 11 is equal to the vertical distance from the hot water injection mechanism 8 to the extraction section 16 of the second bowl 12, and the vertical distance from the brim 7 to the extraction section 13 is equal to the vertical distance from the brim 7 to the extraction section 16.

Next, the operation of the present embodiment will be explained. When a small number of cups (for example, 1 to 3 cups) of coffee liquid are to be extracted, the first filter cup 11 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction unit 13 is placed in the extraction unit 13, coffee powder is put in the filter in an amount corresponding to the number of cups, and then the container 3 with the first filter cup 11 mounted thereon is placed on the base 6 of the coffee maker main body 2. Further, when the coffee maker 1 has a coffee grinder, after the first filter cup 11 is placed in the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, the second filter cup 12 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction unit 16 is placed in the extraction unit 16, coffee powder of a number corresponding to the number of cups is put in the filter, and then the container 3 with the second filter cup 12 is placed on the base 6 of the coffee maker main body 2. Further, when the coffee maker 1 has a coffee grinder, after the second filter cup 12 is placed on the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

Further, the vertical distance from the hot water injection mechanism 8 to the extraction unit 13 of the first bowl 11 and the vertical distance from the hot water injection mechanism 8 to the extraction unit 16 of the second bowl 12 are made equal by the height adjustment unit 14, so that the positional relationship between the hot water injection mechanism 8 and the first bowl 11 and the positional relationship between the hot water injection mechanism 8 and the second bowl 12 are made substantially the same. Therefore, the falling position or temperature drop of the poured hot water is substantially equal in the case of using the first bowl 11 and the second bowl 12, and therefore the coffee liquid can be extracted equally well. In the present embodiment, since the distance in the vertical direction from the brim 7 to the first filter cup 11 is equal to the distance in the vertical direction from the brim 7 to the second filter cup 12, even when the coffee maker 1 has a coffee grinder, the coffee powder is less likely to leak between the first filter cup 11 and the brim 7 when the first filter cup 11 is used, as in the case of using the second filter cup 12.

As described above, the present invention is the coffee maker 1 as follows: the coffee maker comprises a coffee maker main body 2, a container 3, and a filter bowl mechanism 4 arranged above the container 3, wherein hot water is poured from above the filter bowl mechanism 4 by a hot water pouring mechanism 8 provided at a brim portion 7 of the coffee maker main body 2, thereby coffee liquid is extracted from coffee powder in the filter bowl mechanism 4, the filter bowl mechanism 4 is placed on the container 3 by the placing portions 15 and 17, the coffee maker has a first filter bowl 11 for small cup count and a second filter bowl 12 for large cup count, each filter bowl 11 and 12 has an extraction portion 13 and 16, and the first filter bowl 11 has a height adjustment portion 14, thereby the distance in the vertical direction from the hot water pouring mechanism 8 to the extraction portion of the first filter bowl 11 is appropriate when the first filter bowl 11 is used, and coffee extraction at the time of small cup count can be performed favorably.

In the present invention, when the first bowl 11 or the second bowl 12 is placed on the container 3, the vertical distance from the hot water supply means 8 to the extraction part 13 of the first bowl 11 and the vertical distance from the hot water supply means 8 to the extraction part 16 of the second bowl 12 are equal, so that coffee extraction can be performed equally well even in the case of small-cup extraction and in the case of large-cup extraction.

Next, a second embodiment of the present invention will be described with reference to fig. 3 and 4. In the present embodiment, the upper and lower sides of each drawing are also defined as the upper and lower sides of the actual case. 21 is the coffee machine of the present invention. The coffee maker 21 includes a coffee maker main body 2, a container 3, and a bowl mechanism 22.

The coffee maker main body 2 includes an upright portion 5, a base portion 6, and a brim portion 7. The container 3 is placed on the base 6. A hot water injection mechanism 8 is disposed below the brim 7. The vertical positional relationship between the hot water injection mechanism 8 and the brim 7 is fixed.

The container 3 has a container body 9 having a bottom and an open top, and a handle 10 provided on a side of the container body 9. In addition, the container body 9 may be a glass container or a stainless steel vacuum double container.

As the filter cup mechanism 22, as shown in FIG. 3, a first filter cup 23 for small cup number extraction (for example, for 1 to 3 cups of extraction) or a second filter cup 12 for large cup number extraction (for example, for 4 to 6 cups of extraction) is placed on the container body 9 of the container 3. The first filter cup 23 has an extraction portion 24 formed in a tapered manner, and a flange-like mounting portion 25 provided below the extraction portion 24. A height adjusting portion 26 is provided below the mounting portion 25. The height adjusting unit 26 may be integrated with or separate from the mounting unit 25. On the other hand, the second cup 12 has an extraction portion 16 formed so as to be tapered in the lower direction, and a flange-like placement portion 17 provided below the extraction portion 16. Further, the extraction part 24 of the first bowl 23 is formed smaller than the extraction part 16 of the second bowl 12. The height adjusting part 26 is sized so that the distance from the lower end thereof to the upper end of the extraction part 24 of the first cup 23 is the same as the distance from the lower end of the placement part 17 to the upper end of the extraction part 16 of the second cup 12. That is, the height of the upper end of the extraction part 24 of the first cup 23 is equal to the height of the upper end of the extraction part 16 of the second cup 12 in a state of being placed on the container 3. Therefore, the vertical distance from the hot water injection mechanism 8 to the extraction section 24 of the first bowl 23 is equal to the vertical distance from the hot water injection mechanism 8 to the extraction section 16 of the second bowl 12, and the vertical distance from the brim 7 to the extraction section 24 is equal to the vertical distance from the brim 7 to the extraction section 16.

Next, the operation of the present embodiment will be explained. When a small number of cups (for example, 1 to 3 cups) of coffee liquid are to be extracted, the first filter cup 23 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction unit 24 is placed in the extraction unit 24, coffee powder is put in the filter in an amount corresponding to the number of cups, and then the container 3 with the first filter cup 23 is placed on the base 6 of the coffee maker main body 2. Further, when the coffee maker 21 has a coffee grinder, after the first filter cup 23 is placed in the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, the second filter cup 12 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction unit 16 is placed in the extraction unit 16, coffee powder of a number corresponding to the number of cups is put in the filter, and then the container 3 with the second filter cup 12 is placed on the base 6 of the coffee maker main body 2. Further, when the coffee maker 21 has a coffee grinder, after the second filter cup 12 is placed on the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

Further, the vertical distance from the hot water injection mechanism 8 to the extraction section 24 of the first bowl 23 and the vertical distance from the hot water injection mechanism 8 to the extraction section 16 of the second bowl 12 are made equal by the height adjustment portion 26, so that the positional relationship between the hot water injection mechanism 8 and the extraction section 24 of the first bowl 23 and the positional relationship between the hot water injection mechanism 8 and the extraction section 16 of the second bowl 12 are made substantially the same. Therefore, the falling position or temperature drop of the poured hot water is substantially equal in the case of using the first bowl 23 and the second bowl 12, and therefore the coffee liquid can be extracted equally well. In the present embodiment, since the distance in the vertical direction from the brim 7 to the extraction portion 24 of the first filter cup 23 is equal to the distance in the vertical direction from the brim 7 to the extraction portion 16 of the second filter cup 12, it is possible to prevent coffee grounds from leaking between the first filter cup 23 and the brim 7 even when the coffee maker 21 has a coffee grinder, as in the case of using the second filter cup 12.

As described above, the present invention is the coffee maker 1 as follows: the coffee maker comprises a coffee maker main body 2, a container 3, and a filter cup mechanism 22 arranged above the container 3, wherein hot water is injected from above the filter cup mechanism 22 by a hot water injection mechanism 8 arranged at a brim 7 of the coffee maker main body 2, thereby coffee liquid is extracted from coffee powder in the filter cup mechanism 22, the filter cup mechanism 22 is placed on the container 3, the coffee maker comprises a first filter cup 23 for small cup count and a second filter cup 12 for large cup count, each filter cup 23, 12 comprises an extraction part 24, 16, and the first filter cup 23 comprises a height adjustment part 26, thereby when the first filter cup 23 is used, the vertical distance from the hot water injection mechanism 8 to the extraction part 24 of the first filter cup 23 is proper, and coffee extraction at the time of small cup count can be performed well.

In the present invention, when the first and second filter cups 23 and 12 are placed on the container 3, the vertical distance from the hot water supply means 8 to the extraction part 24 of the first filter cup 23 and the vertical distance from the hot water supply means 8 to the extraction part 16 of the second filter cup 12 are equal to each other, and coffee extraction can be performed equally well even in the case of small cup number extraction and in the case of large cup number extraction.

Next, a third embodiment of the present invention will be described with reference to fig. 5 and 6. In the present embodiment, the upper and lower sides of each drawing are also defined as the upper and lower sides of the actual case. 31 is the coffee machine of the present invention. The coffee maker 31 includes a coffee maker main body 2, a container 3, and a filter bowl mechanism 32.

The coffee maker main body 2 includes an upright portion 5, a base portion 6, and a brim portion 7. The container 3 is placed on the base 6. A hot water injection mechanism 8 is disposed below the brim 7. The vertical positional relationship between the hot water injection mechanism 8 and the brim 7 is fixed.

The container 3 has a container body 9 having a bottom and an open top, and a handle 10 provided on a side of the container body 9. In addition, the container body 9 may be a glass container or a stainless steel vacuum double container.

The filter cup mechanism 32 is constituted by a first filter cup 33 for small-cup extraction (for example, for 1 to 3-cup extraction), a second filter cup 34 for large-cup extraction (for example, for 4 to 6-cup extraction), and a support mechanism 35. The first bowl 33 has an extraction portion 36 formed to be tapered downward, and a flange-like hanging portion 37 provided to project laterally from the outer surface of the extraction portion 36. Similarly, the second bowl 34 includes an extraction portion 38 formed to be tapered downward, and a flange-like hanging portion 39 provided to project laterally from the outer surface of the extraction portion 38. The support mechanism 35 includes a placement portion 40 for placing on the container body 9 of the container 3, and a support portion 41 extending upward from the placement portion 40 in a cylindrical shape. The support portion 41 is used to catch the hanging portions 37, 39. That is, the support mechanism 35 is placed on the container body 9 of the container 3, and the first filter bowl 33 or the second filter bowl 34 is placed on the support portion 41 of the support mechanism 35. Further, the extraction part 36 of the first bowl 33 is formed smaller than the extraction part 38 of the second bowl 34. Further, the vertical distance from the upper end of the extraction portion 36 in the first bowl 33 to the portion of the hanging portion 37 abutting against the support portion 41 is the same as the vertical distance from the upper end of the extraction portion 38 in the second bowl 34 to the portion of the hanging portion 39 abutting against the support portion 41. That is, in a state of being placed on the container 3, the height of the upper end of the extraction part 36 of the first bowl 33 is equal to the height of the upper end of the extraction part 38 of the second bowl 34. Therefore, the vertical distance from the hot water injection mechanism 8 to the extraction section 36 of the first bowl 33 is equal to the vertical distance from the hot water injection mechanism 8 to the extraction section 38 of the second bowl 34, and the vertical distance from the brim 7 to the extraction section 36 is equal to the vertical distance from the brim 7 to the extraction section 38.

Next, the operation of the present embodiment will be explained. First, the support mechanism 35 is placed on the container body 9 of the container 3 in advance. Then, when a small number of cups (for example, 1 to 3 cups) of coffee liquid are to be extracted, the first filter cup 33 is placed on the support portion 41 of the support mechanism 35, a filter (not shown) having a size corresponding to the size of the extraction portion 36 is placed in the extraction portion 36, coffee powder corresponding to the number of cups is put in the filter, and then the container 3 containing the first filter cup 33 and the support mechanism 35 is placed on the base portion 6 of the coffee maker main body 2. Further, when the coffee maker 31 has a coffee grinder, after the first filter cup 33 is placed on the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, the second filter cup 34 is placed on the support portion 41 of the support mechanism 35, a filter (not shown) having a size corresponding to the size of the extraction portion 38 is placed in the extraction portion 38, coffee powder of a number corresponding to the number of cups is put in the filter, and then the container 3 containing the second filter cup 34 and the support mechanism 35 is placed on the base portion 6 of the coffee maker main body 2. Further, when the coffee maker 31 has a coffee grinder, after the second bowl 34 is placed in the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

Further, the vertical distance from the hot water injection mechanism 8 to the extraction unit 36 of the first bowl 33 and the vertical distance from the hot water injection mechanism 8 to the extraction unit 38 of the second bowl 34 are made equal to each other by the support portion 41 of the support mechanism 35 and the hanging portions 37 and 39 of the respective bowls 33 and 34, and the positional relationship between the hot water injection mechanism 8 and the extraction unit 36 of the first bowl 33 and the positional relationship between the hot water injection mechanism 8 and the extraction unit 38 of the second bowl 34 are made substantially equal to each other. Therefore, the falling position or temperature drop of the poured hot water is substantially equal in the case of using the first bowl 33 and the second bowl 34, and therefore the coffee liquid can be extracted equally well. In the present embodiment, since the vertical distance from the brim 7 to the extraction portion 36 of the first filter cup 33 is equal to the vertical distance from the brim 7 to the extraction portion 38 of the second filter cup 34, the coffee powder is less likely to leak between the first filter cup 33 and the brim 7 even when the coffee maker 31 has a coffee grinder, as in the case of using the second filter cup 34.

As described above, the present invention is the coffee maker 31 as follows: the coffee maker comprises a coffee maker main body 2, a container 3, and a filter cup mechanism 32 arranged above the container 3, wherein hot water is injected from above the filter cup mechanism 32 by a hot water injection mechanism 8 arranged at a brim portion 7 of the coffee maker main body 2, thereby coffee liquid is extracted from coffee powder in the filter cup mechanism 32, the filter cup mechanism 32 comprises a first filter cup 33 for a small cup number and a second filter cup 34 for a large cup number, and a support mechanism 35 supporting the first filter cup 33 and the second filter cup 34, each filter cup 33, 34 comprises an extraction portion 36, 38 and a flange-shaped hanging portion 37, 39 for placing on the support mechanism 35, and the support mechanism 35 comprises a flange-shaped placing portion 40 for placing on the container 3, and a support portion 41 extending in a cylindrical shape from the placing portion 40 and for catching the hanging portion 37, 39, thereby when the first filter cup 33 is used, the hot water injection mechanism 8 is injected to the extraction portion 36 of the first filter cup 33 The distance in the vertical direction is appropriate, and coffee extraction can be performed well when the number of cups is small.

In the present invention, when the first bowl 33 or the second bowl 34 is placed on the container 3, the distance in the vertical direction from the hot water supply means 8 to the extraction part 36 of the first bowl 33 is equal to the distance from the hot water supply means 8 to the extraction part 38 of the second bowl 34, and therefore coffee extraction can be performed equally well even in the case of small-cup extraction and in the case of large-cup extraction.

Next, a fourth embodiment of the present invention will be described with reference to fig. 7 and 8. In the present embodiment, the upper and lower sides of each drawing are also defined as the upper and lower sides of the actual case. 51 is the coffee machine of the present invention. The coffee maker 51 includes a coffee maker main body 52, a container 3, and a filter bowl mechanism 53.

The coffee maker main body 52 has an upright portion 5, a base portion 6, and a brim portion 7. A height adjustment mechanism 54 that can be raised and lowered in the vertical direction is provided on the base 6. The height adjustment mechanism 54 may be configured to be movable by power or manually. In addition, the height adjustment mechanism 54 may be separate from the coffee maker body 52. The container 3 is placed on the height adjusting mechanism 54. A hot water injection mechanism 8 is disposed below the brim 7. The vertical positional relationship between the hot water injection mechanism 8 and the brim 7 is fixed.

The container 3 has a container body 9 having a bottom and an open top, and a handle 10 provided on a side of the container body 9. In addition, the container body 9 may be a glass container or a stainless steel vacuum double container.

As the filter cup mechanism 53, as shown in FIG. 7, the first filter cup 23 for small cup number extraction (for example, for 1 to 3 cups of extraction) or the second filter cup 12 for large cup number extraction (for example, for 4 to 6 cups of extraction) is placed on the container body 9 of the container 3 as shown in FIG. 8. The first filter cup 23 has an extraction portion 24 formed in a tapered manner, and a flange-like mounting portion 25 provided below the extraction portion 24. On the other hand, the second cup 12 has an extraction portion 16 formed so as to be tapered in the lower direction, and a flange-like placement portion 17 provided below the extraction portion 16. Further, the extraction part 24 of the first bowl 23 is formed smaller than the extraction part 16 of the second bowl 12.

The dimension of the height adjustment mechanism 54 protruding from the base 6, that is, the height difference between the upper position and the lower position of the height adjustment mechanism 54, is set as follows: the difference between the vertical distance from the upper end of the container main body 9 to the upper end of the extraction part 24 in the state where the first filter cup 23 is placed in the container 3 and the vertical distance from the upper end of the container main body 9 to the upper end of the extraction part 16 in the state where the second filter cup 12 is placed in the container 3 is equal to the difference. That is, the height of the upper end of the extraction part 24 when the container 3 and the first filter cup 23 are placed on the height adjustment mechanism 54 in the upper position is equal to the height of the upper end of the extraction part 16 when the container 3 and the second filter cup 12 are placed on the height adjustment mechanism 54 in the lower position. Therefore, under the above conditions, the vertical distance from the hot water injection mechanism 8 to the extraction section 24 of the first bowl 23 is equal to the vertical distance from the hot water injection mechanism 8 to the extraction section 16 of the second bowl 12, and the vertical distance from the brim 7 to the extraction section 24 is also equal to the vertical distance from the brim 7 to the extraction section 16.

Next, the operation of the present embodiment will be explained. When a small number of cups (for example, 1 to 3 cups) of coffee liquid are to be extracted, the first filter cup 23 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction unit 24 is placed in the extraction unit 24, coffee powder is put in the filter in an amount corresponding to the number of cups, and then the container 3 with the first filter cup 23 mounted thereon is placed on the height adjustment mechanism 54 provided on the base 6 of the coffee maker main body 52. Then, the height adjusting mechanism 54 is projected to the upper position by operating an operation unit, not shown. Further, when the coffee maker 51 has a coffee grinder, after the first filter cup 23 is placed in the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, the second filter cup 12 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction unit 16 is placed in the extraction unit 16, coffee powder of a number corresponding to the number of cups is put in the filter, and then the container 3 with the second filter cup 12 is placed on the height adjustment mechanism 54 of the base 6 of the coffee maker main body 52. In this case, the height adjusting mechanism 54 is not projected upward from the upper surface of the base 6, but is held at a lower position. Further, when the coffee maker 51 has a coffee grinder, after the second filter cup 12 is placed on the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

Further, the vertical distance from the hot water injection mechanism 8 to the extraction part 24 of the first bowl 23 and the vertical distance from the hot water injection mechanism 8 to the extraction part 16 of the second bowl 12 are made equal by the height adjustment mechanism 54, so that the positional relationship between the hot water injection mechanism 8 and the extraction part 24 of the first bowl 23 and the positional relationship between the hot water injection mechanism 8 and the extraction part 16 of the second bowl 12 are made substantially the same. Therefore, the falling position or temperature drop of the poured hot water is substantially equal in the case of using the first bowl 23 and the second bowl 12, and therefore the coffee liquid can be extracted equally well. In the present embodiment, since the distance in the vertical direction from the brim 7 to the extraction portion 24 of the first filter cup 23 is equal to the distance in the vertical direction from the brim 7 to the extraction portion 16 of the second filter cup 12, it is possible to prevent coffee grounds from leaking between the first filter cup 23 and the brim 7 even when the coffee maker 51 has a coffee grinder, as in the case of using the second filter cup 12.

As described above, the present invention is the coffee maker 51 as follows: the coffee maker comprises a coffee maker main body 52, a container 3, and a filter bowl mechanism 53 arranged above the container 3, wherein hot water is poured from above the filter bowl mechanism 53 by a hot water pouring mechanism 8 provided at a brim portion 7 of the coffee maker main body 52, thereby coffee liquid is extracted from coffee powder in the filter bowl mechanism 53, the filter bowl mechanism 53 is placed on the container 3, the coffee maker has a first filter bowl 23 for small cup count and a second filter bowl 12 for large cup count, each filter bowl 23, 12 has an extraction portion 24, 16, and the coffee maker main body 52 has a height adjusting mechanism 54 of the filter bowl mechanism 53, thereby the distance in the vertical direction from the hot water pouring mechanism 8 to the extraction portion 24 of the first filter bowl 23 is appropriate when the first filter bowl 23 is used, and coffee extraction at the time of small cup count can be performed well.

In the present invention, when the first and second strainers 23 and 12 are placed on the container 3 by the height adjustment mechanism 54, the distance in the vertical direction from the hot water injection mechanism 8 to the extraction part 24 of the first strainers 23 is equal to the distance in the vertical direction from the hot water injection mechanism 8 to the extraction part 16 of the second strainers 12, and therefore coffee extraction can be performed equally well even in both the case of small cup number extraction and the case of large cup number extraction.

Next, a fifth embodiment of the present invention will be described with reference to fig. 9 and 10. In the present embodiment, the upper and lower sides of each drawing are also defined as the upper and lower sides of the actual case. 61 is the coffee machine of the present invention. The coffee maker 61 includes a coffee maker main body 62, the container 3, and a filter bowl mechanism 53.

The coffee maker main body 62 includes an upright portion 5, a base portion 6, and a brim portion 7. A height adjusting mechanism 63 that is movable in the vertical direction is provided on the upright setting portion 5. The height adjustment mechanism 63 may be configured to be movable up and down by power, or may be configured to be movable up and down manually. In addition, the height adjustment mechanism 63 may be separate from the coffee maker main body 62. The bowl mechanism 53 is mounted on the height adjusting mechanism 63. A hot water injection mechanism 8 is disposed below the brim 7. The vertical positional relationship between the hot water injection mechanism 8 and the brim 7 is fixed.

The container 3 has a container body 9 having a bottom and an open top, and a handle 10 provided on a side of the container body 9. In addition, the container body 9 may be a glass container or a stainless steel vacuum double container.

As the filter cup mechanism 53, as shown in FIG. 9, the first filter cup 23 for small cup number extraction (for example, for 1 to 3 cups of extraction) or the second filter cup 12 for large cup number extraction (for example, for 4 to 6 cups of extraction) is placed on the height adjusting mechanism 63 as shown in FIG. 10. The first filter cup 23 has an extraction portion 24 formed in a tapered manner, and a flange-like mounting portion 25 provided below the extraction portion 24. On the other hand, the second cup 12 has an extraction portion 16 formed so as to be tapered in the lower direction, and a flange-like placement portion 17 provided below the extraction portion 16. Further, the extraction part 24 of the first bowl 23 is formed smaller than the extraction part 16 of the second bowl 12.

The height difference between the height when the height adjusting mechanism 63 is at the lower position and the height when it is at the upper position is set as: the difference between the vertical distance from the upper end of the height adjustment mechanism 63 to the upper end of the extraction part 24 in the state where the first filter cup 23 is placed on the height adjustment mechanism 63 and the vertical distance from the upper end of the height adjustment mechanism 63 to the upper end of the extraction part 16 in the state where the second filter cup 12 is placed on the height adjustment mechanism 63. That is, the height of the upper end of the extraction part 24 in a state where the first filter cup 23 is placed on the height adjustment mechanism 63 in the upper position is equal to the height of the upper end of the extraction part 16 in a state where the second filter cup 12 is placed on the height adjustment mechanism 63 in the lower position. Therefore, under the above conditions, the vertical distance from the hot water injection mechanism 8 to the extraction section 24 of the first bowl 23 is equal to the vertical distance from the hot water injection mechanism 8 to the extraction section 16 of the second bowl 12, and the vertical distance from the brim 7 to the extraction section 24 is also equal to the vertical distance from the brim 7 to the extraction section 16.

Next, the operation of the present embodiment will be explained. First, the container 3 is placed on the base 6 of the coffee maker main body 62. Then, when a small number (for example, 1 to 3 cups) of coffee liquid is to be extracted, a filter (not shown) having a size corresponding to the size of the extraction unit 24 is placed in the extraction unit 24 of the first filter cup 23, coffee powder having a number corresponding to the number of cups is placed in the filter, and then the first filter cup 23 is placed on the height adjustment mechanism 63. Then, the height adjusting mechanism 63 is held at the upper position, or the height adjusting mechanism 63 is moved from the lower position to the upper position by operating an operation unit, not shown. Further, when the coffee maker 61 has a coffee grinder, after the first filter cup 23 is placed in the coffee maker main body 62, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. In either case, the height adjusting mechanism 63 may be moved to an upper position, and then the first filter bowl 23 may be placed on the height adjusting mechanism 63. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, a filter (not shown) having a size corresponding to the size of the extraction unit 16 is placed in the extraction unit 16 of the second filter cup 12, coffee powder of a number corresponding to the number of cups is put in the filter, and then the second filter cup 12 is placed on the height adjustment mechanism 63. Then, the height adjusting mechanism 63 is held at the lower position, or the height adjusting mechanism 63 is moved from the upper position to the lower position by operating an operation unit, not shown. Further, when the coffee maker 61 has a coffee grinder, after the second filter cup 12 is placed on the coffee maker main body 62, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder. In either case, the height adjusting mechanism 63 may be moved to the lower position, and then the second filter cup 12 may be placed on the height adjusting mechanism 63. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

Further, the vertical distance from the hot water injection mechanism 8 to the extraction part 24 of the first bowl 23 and the vertical distance from the hot water injection mechanism 8 to the extraction part 16 of the second bowl 12 are made equal by the height adjustment mechanism 63, so that the positional relationship between the hot water injection mechanism 8 and the extraction part 24 of the first bowl 23 and the positional relationship between the hot water injection mechanism 8 and the extraction part 16 of the second bowl 12 are made substantially the same. Therefore, the falling position or temperature drop of the poured hot water is substantially equal in the case of using the first bowl 23 and the second bowl 12, and therefore the coffee liquid can be extracted equally well. In the present embodiment, since the distance in the vertical direction from the brim 7 to the extraction portion 24 of the first filter cup 23 is equal to the distance in the vertical direction from the brim 7 to the extraction portion 16 of the second filter cup 12, the coffee powder is less likely to leak between the first filter cup 23 and the brim 7 even when the coffee maker 51 has a coffee grinder, as in the case of using the second filter cup 12.

As described above, the present invention is the coffee maker 61 as follows: the coffee machine comprises a coffee machine main body 62, a container 3, and a filter cup mechanism 53 arranged above the container 3, wherein hot water is injected from above the filter cup mechanism 53 by a hot water injection mechanism 8 provided at a brim 7 of the coffee machine main body 62, thereby extracting coffee liquid from coffee powder in the filter cup mechanism 53, the filter cup mechanism 53 is placed on the coffee machine main body 62, the coffee machine main body has a first filter cup 23 for small cup count and a second filter cup 12 for large cup count, each filter cup 23, 12 has an extraction part 24, 16, and the coffee machine main body 62 has a height adjustment mechanism 63 of the filter cup mechanism 53, thereby making the distance in the vertical direction from the hot water injection mechanism 8 to the extraction part 24 of the first filter cup 23 proper when the first filter cup 23 is used, and coffee extraction at the time of small cup count can be performed well.

In the present invention, when the first cup 23 or the second cup 12 is placed on the height adjusting mechanism 63, the vertical distance from the hot water pouring mechanism 8 to the extraction part 24 of the first cup 23 is adjusted to be equal to the vertical distance from the hot water pouring mechanism 8 to the extraction part 16 of the second cup 12, so that coffee extraction can be performed equally well even in the case of small cup number extraction or large cup number extraction.

Next, a sixth embodiment of the present invention will be described with reference to fig. 11 and 12.

The eave portion 7 is provided with a height adjustment mechanism 73 for moving the hot water injection mechanism 8 in the vertical direction. The height adjustment mechanism 73 may be configured to be movable up and down by power, or may be configured to be movable up and down manually. In this way, the height of the hot water injection mechanism 8 can be changed by operating the height adjustment mechanism 73.

The container 3 has a container body 9 having a bottom and an open top, and a handle 10 provided on a side of the container body 9. In addition, the container body 9 may be a glass container or a stainless steel vacuum double container.

As the filter cup mechanism 53, as shown in FIG. 11, a first filter cup 23 for small cup number extraction (for example, for 1 to 3 cups of extraction) or a second filter cup 12 for large cup number extraction (for example, for 4 to 6 cups of extraction) is placed on the container body 9 of the container 3 as shown in FIG. 12. The first filter cup 23 has an extraction portion 24 formed in a tapered manner, and a flange-like mounting portion 25 provided below the extraction portion 24. On the other hand, the second cup 12 has an extraction portion 16 formed so as to be tapered in the lower direction, and a flange-like placement portion 17 provided below the extraction portion 16. Further, the extraction part 24 of the first bowl 23 is formed smaller than the extraction part 16 of the second bowl 12.

As described above, the hot water injection mechanism 8 is moved up and down by the height adjustment mechanism 73. The height difference between the lower position and the upper position of the hot water injection mechanism 8 is set as follows: the difference between the vertical distance from the upper end of the container main body 9 to the upper end of the extraction part 24 of the first filter cup 23 when the first filter cup 23 is placed in the container 3 and the vertical distance from the upper end of the container main body 9 to the upper end of the extraction part 16 of the second filter cup 12 when the second filter cup 12 is placed in the container 3 is equal to. That is, the vertical distance between the hot water injection mechanism 8 and the extraction unit 24 of the first bowl 23 when the hot water injection mechanism 8 is set to the lower position by the height adjustment mechanism 73 in a state where the first bowl 23 is placed on the vessel 3 and the vessel 3 on which the first bowl 23 is placed on the base 6, and the vertical distance between the hot water injection mechanism 8 and the extraction unit 16 of the second bowl 12 when the hot water injection mechanism 8 is set to the upper position by the height adjustment mechanism 73 in a state where the second bowl 12 is placed on the vessel 3 and the vessel 3 on which the second bowl 12 is placed on the base 6 are equal to each other.

When a small number (for example, 1 to 3 cups) of coffee liquid is to be extracted, the first filter cup 23 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction part 24 is placed in the extraction part 24 of the first filter cup 23, coffee powder having a number corresponding to the number of cups is placed in the filter, and then the container 3 on which the first filter cup 23 is placed on the base 6. Then, the hot water injection mechanism 8 is held at the lower position, or the hot water injection mechanism 8 is moved from the upper position to the lower position by operating an operation unit, not shown. Further, when the coffee maker 71 has a coffee grinder, after the first filter cup 23 is placed on the coffee maker main body 72, coffee powder pulverized by the coffee grinder is transferred and stored into the filter. In either case, the hot water injection mechanism 8 may be moved to a lower position by the height adjustment mechanism 73, and then the first filter bowl 23 may be placed on the coffee maker main body 72. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, the second filter cup 12 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction unit 16 is placed in the extraction unit 16 of the second filter cup 12, coffee powder of a number corresponding to the number of cups is put in the filter, and then the container 3 on which the second filter cup 12 is placed on the base 6.

Further, when the coffee maker 71 has a coffee grinder, after the second filter cup 12 is placed on the coffee maker main body 72, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. In either case, the hot water injection mechanism 8 may be moved to an upper position by the height adjustment mechanism 73, and then the second filter cup 12 may be placed on the coffee maker main body 72. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

Further, the vertical distance from the hot water injection mechanism 8 to the extraction part 24 of the first bowl 23 and the vertical distance from the hot water injection mechanism 8 to the extraction part 16 of the second bowl 12 are made equal by the height adjustment mechanism 73, so that the positional relationship between the hot water injection mechanism 8 and the extraction part 24 of the first bowl 23 and the positional relationship between the hot water injection mechanism 8 and the extraction part 16 of the second bowl 12 are made substantially the same. Therefore, the falling position or temperature drop of the poured hot water is substantially equal in the case of using the first bowl 23 and the second bowl 12, and therefore the coffee liquid can be extracted equally well.

As described above, the present invention is the coffee maker 71 as follows: the coffee maker comprises a coffee maker main body 72, a container 3, and a filter bowl mechanism 53 arranged above the container 3, wherein hot water is poured from above the filter bowl mechanism 53 by a hot water pouring mechanism 8 provided at a brim portion 7 of the coffee maker main body 72, thereby extracting coffee liquid from coffee powder in the filter bowl mechanism 53, the filter bowl mechanism 53 is placed on the container 3, the coffee maker has a first filter bowl 23 for small cup count and a second filter bowl 12 for large cup count, each filter bowl 23, 12 has an extraction portion 24, 16, and the coffee maker main body 72 has a height adjusting mechanism 73 of the hot water pouring mechanism 8, so that the vertical distance from the hot water pouring mechanism 8 to the extraction portion 24 of the first filter bowl 23 when the first filter bowl 23 is used becomes appropriate, and coffee extraction at the time of small cup count can be performed well.

In the present invention, when the first and second strainers 23 and 12 are placed on the container 3, the vertical distance from the hot water injection mechanism 8 to the extraction unit 24 of the first strainers 23 is adjusted by the height adjustment mechanism 73 to be equal to the vertical distance from the hot water injection mechanism 8 to the extraction unit 16 of the second strainers 12, so that coffee extraction can be performed equally well even in the case of small cup number extraction or large cup number extraction.

The second placement portion 88 is provided to extend laterally from one end of the extension portion 87. The engagement portion 89 is provided at the other end of the extension portion 87. A first engagement support portion 90 that engages with the engagement portion 89 is provided at an upper end portion of the extraction portion 84, and a second engagement support portion 91 that engages with the engagement portion 89 is provided at a lower portion of the first placement portion 86. The first placement portion 86 and the second placement portion 88 are formed to have the same diameter.

As shown in fig. 15, the engaging portion 89 of the attachment 85 can be engaged with the second engaging support portion 91 of the bowl 83 with the engaging portion 89 being located above and the second placement portion 88 being located below. As shown in fig. 16, the engaging portion 89 of the attachment 85 may be located downward and the second placement portion 88 may be located upward, and the engaging portion 89 may be engaged with the first engaging support portion 90 of the bowl 83. In the latter case, the attachment 84 expands the extraction section 85 upward. In other words, in the latter case, the extraction portion 85 of the bowl 83 and the extension 87 of the attachment 84 constitute an extended extraction portion 92. In the former case, the vertical distance from the lower end of the second placement portion 88 to the upper end of the extraction portion 85 is equal to the vertical distance from the lower end of the first placement portion 86 to the upper end of the extended extraction portion 92 in the latter case. That is, the height of the upper end of the extraction section 85 in the former case is equal to the height of the upper end of the extended extraction section 92 in the latter case. Therefore, the vertical distance from the hot water injection mechanism 8 to the upper end of the extraction section 85 in the former case is equal to the vertical distance from the hot water injection mechanism 8 to the upper end of the extended extraction section 92 in the latter case, and the vertical distance from the brim 7 to the extraction section 85 is equal to the vertical distance from the brim 7 to the extended extraction section 92.

Next, the operation of the present embodiment will be explained. When a small number (for example, 1 to 3 cups) of coffee liquid is to be extracted, the filter bowl 83 is placed above the attachment 84 by placing the second placement portion 88 of the attachment 84 on the container body 9 of the container 3 in a posture in which the second placement portion 88 is positioned downward, and engaging the engaging portion 89 of the attachment 84 with the second engaging support portion 91 of the filter bowl 83. Then, a filter, not shown, having a size corresponding to the size of the extraction unit 85 is placed in the extraction unit 85 of the filter cup 83, coffee powder is put in the filter in an amount corresponding to the number of cups, and then the container 3 on which the filter cup 83 is placed on the base 6. Further, when the coffee maker 81 has a coffee grinder, after the filter cup 83 is placed on the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, the attachment 84 is placed above the filter cup 83 by placing the first placement portion 88 of the filter cup 83 on the container body 9 of the container 3, setting the engagement portion 89 of the attachment 84 to a downward posture, and engaging the engagement portion 89 with the first engagement support portion 90 of the filter cup 83. In this way, the extension 87 of the attachment 84 extends the extraction section 85 of the bowl 83 upward to form the extended extraction section 92. Then, a filter, not shown, having a size corresponding to the size of the extended extraction unit 92 is placed in the extended extraction unit 92, coffee powder is put in the filter in an amount corresponding to the number of cups, and then the container 3 on which the filter cup 83 and the attachment 84 are placed is placed on the base 6. Further, when the coffee maker 81 has a coffee grinder, after the filter cup 83 is placed on the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

Further, as shown in fig. 13, the vertical distance from the hot water injection mechanism 8 to the extraction unit 85 of the bowl 83 when the attachment 84 is attached to the lower side of the bowl 83 is equal to the vertical distance from the hot water injection mechanism 8 to the extended extraction unit 92 when the attachment 84 is attached to the upper side of the bowl 83 as shown in fig. 14, and the positional relationship between the hot water injection mechanism 8 and the extraction unit 85 of the bowl 83 in the former case is substantially equal to the positional relationship between the hot water injection mechanism 8 and the extended extraction unit 92 in the latter case. Therefore, when only the filter bowl 83 is used, the drop position or temperature drop of the hot water to be poured is substantially equal to that of the extended extraction portion 92 constituted by the filter bowl 83 and the attachment 84, and therefore the coffee liquid can be extracted equally well.

As described above, the present invention is the coffee maker 81 as follows: comprises a coffee machine body 2, a container 3, and a filter cup mechanism 82 arranged above the container 3, wherein hot water is injected from above the filter cup mechanism 82 by a hot water injection mechanism 8 provided at a brim portion 7 of the coffee machine body 2, thereby extracting coffee liquid from coffee powder in the filter cup mechanism 82, the filter cup mechanism 82 comprises a filter cup 83 and a fitting 84 which is extended upward from an upper end portion of an extraction portion 85 of the filter cup 83 and is detachable, the filter cup 83 comprises the extraction portion 85 and a flange-shaped first mounting portion 86 for mounting on the container 3, the fitting 84 comprises an extension portion 87 for extending the extraction portion 85, a second mounting portion 88 which is extended laterally from one side of the extension portion 87 in a flange shape, and an engagement portion 89 provided at the other side of the extension portion 87, and a first engagement support portion 90 which is selectively engaged with the engagement portion 89 is provided at an upper portion of the extraction portion 85, by providing the second engagement support portion 91 that selectively engages with the engagement portion 89 at the lower portion of the first placement portion 86, the distance in the vertical direction from the hot water injection mechanism 8 to the extraction portion 85 of the filter cup 83 when the filter cup 83 is used becomes appropriate, and coffee extraction at the time of extraction with a small number of cups can be performed well.

In the present invention, since the vertical distance from the hot water injection mechanism 8 to the upper end of the attachment 84 when the first placement portion 86 is placed on the container 3 is equal to the vertical distance from the hot water injection mechanism 8 to the upper end of the extraction portion 85 when the second placement portion 88 is placed on the container 3, coffee extraction can be performed equally well even in the case of small cup number extraction and in the case of large cup number extraction.

Next, an eighth embodiment of the present invention will be described with reference to fig. 17 and 18. In the present embodiment, the upper and lower sides of each drawing are also defined as the upper and lower sides of the actual case. 101 is a coffee machine of the present invention. The coffee maker 101 includes a coffee maker main body 2, a container mechanism 102, and a bowl mechanism 53.

The coffee maker main body 2 includes an upright portion 5, a base portion 6, and a brim portion 7. The container mechanism 102 is placed on the base 6. A hot water injection mechanism 8 is disposed below the brim 7. The vertical positional relationship between the hot water injection mechanism 8 and the brim 7 is fixed.

As the container means 102, a first container 103 for small cup count (for example, for 1 to 3 cup extractions) as shown in FIG. 17, or a second container 104 for large cup count (for example, for 4 to 6 cup extractions) as shown in FIG. 18 is placed on the base 6 of the coffee maker main body 2. The first container 103 includes a container body 105 having a bottom and an open top, and a handle 106 provided on a side of the container body 105. Similarly, the second container 104 includes a container body 107 having a bottom and an open top, and a handle 108 provided on a side of the container body 107. In addition, a glass container, a stainless steel vacuum double container, or the like may be used for each of the container bodies 105 and 107.

As the filter cup mechanism 53, as shown in FIG. 17, a first filter cup 23 for small-cup extraction (for example, 1 to 3 cups for extraction) is placed on the container body 105 of the first container 103, or as shown in FIG. 18, a second filter cup 12 for large-cup extraction (for example, 4 to 6 cups for extraction) is placed on the container body 107 of the second container 104. The first filter cup 23 has an extraction portion 24 formed in a tapered manner, and a flange-like mounting portion 25 provided below the extraction portion 24. On the other hand, the second cup 12 has an extraction portion 16 formed so as to be tapered in the lower direction, and a flange-like placement portion 17 provided below the extraction portion 16. Further, the extraction part 24 of the first bowl 23 is formed smaller than the extraction part 16 of the second bowl 12. The vertical distance from the upper end of the extraction unit 24 to the lower end of the container body 105 when the first filter cup 23 is placed on the container body 105 of the first container 103 is the same as the vertical distance from the upper end of the extraction unit 16 to the lower end of the container body 107 when the second filter cup 12 is placed on the container body 107 of the second container 104. That is, the height of the upper end of the extraction portion 24 of the first filter cup 23 when the first filter cup 23 and the first container 103 in the former state are placed on the base portion 6 of the coffee maker main body 2 is the same as the height of the upper end of the extraction portion 16 of the second filter cup 12 when the second filter cup 12 and the second container 104 in the latter state are placed on the base portion 6 of the coffee maker main body 2. Therefore, the vertical distance from the hot water injection mechanism 8 to the extraction section 24 of the first bowl 23 is equal to the vertical distance from the hot water injection mechanism 8 to the extraction section 16 of the second bowl 12, and the vertical distance from the brim 7 to the extraction section 24 is equal to the vertical distance from the brim 7 to the extraction section 16.

Next, the operation of the present embodiment will be explained. When a small number of cups (for example, 1 to 3 cups) of coffee liquid are to be extracted, the first filter cup 23 is placed on the first container 103, a filter (not shown) having a size corresponding to the size of the extraction unit 24 is placed in the extraction unit 24, coffee powder is placed in the filter in an amount corresponding to the number of cups, and then the first container 103 containing the first filter cup 23 is placed on the base 6 of the coffee maker main body 2. Further, when the coffee maker 101 has a coffee grinder, after the first filter cup 23 is placed in the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, the second filter cup 12 is placed on the second container 104, a filter (not shown) having a size corresponding to the size of the extraction unit 16 is placed in the extraction unit 16, coffee powder of a number corresponding to the number of cups is put in the filter, and then the second container 104 containing the second filter cup 12 is placed on the base 6 of the coffee maker main body 2. Further, when the coffee maker 101 has a coffee grinder, after the second filter cup 12 is placed on the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

Further, the vertical distance from the hot water injection mechanism 8 to the extraction part 24 of the first bowl 23 when the first bowl 23 and the first container 103 are combined is equal to the vertical distance from the hot water injection mechanism 8 to the extraction part 16 of the second bowl 12 when the second bowl 12 and the second container 104 are combined, so that the positional relationship between the hot water injection mechanism 8 and the first bowl 23 is substantially the same as the positional relationship between the hot water injection mechanism 8 and the second bowl 12. Therefore, the falling position or temperature drop of the poured hot water is substantially equal in the case of using the first bowl 23 and the second bowl 12, and therefore the coffee liquid can be extracted equally well. In the present embodiment, since the distance in the vertical direction from the brim 7 to the first filter cup 23 is equal to the distance in the vertical direction from the brim 7 to the second filter cup 12, even when the coffee maker 101 has a coffee grinder, the coffee powder is less likely to leak between the coffee grinder and the brim 7 when the first filter cup 23 is used, as in the case of using the second filter cup 12.

As described above, the present invention is the coffee maker 101 as follows: the coffee maker comprises a coffee maker main body 2, a container mechanism 102, and a filter cup mechanism 53 arranged on the container mechanism 102, wherein hot water is poured from above the filter cup mechanism 53 by a hot water pouring mechanism 8 arranged on a brim portion 7 of the coffee maker main body 2, thereby coffee liquid is extracted from coffee powder in the filter cup mechanism 53, the container mechanism 102 has a first container 103 for small cup count and a second container 104 for large cup count, the filter cup mechanism 53 has a first filter cup 23 for small cup count and a second filter cup 12 for large cup count, each filter cup 23, 12 has an extraction portion 24, 16, the first filter cup 23 has a placement portion 25 for placing on the first container 103, the second filter cup 12 has a placement portion 17 for placing on the second container 104, and the height of the first container 103 is made higher than the height of the second container 104, thereby the distance from the hot water pouring mechanism 8 to the first filter cup 23 when the first filter cup 23 is used becomes appropriate Therefore, coffee extraction can be performed well when the number of cups is small.

In the present invention, the distance in the vertical direction from the hot water supply means 8 to the first filter cup 23 in the state where the first filter cup 23 is placed in the first container 103 is equal to the distance in the vertical direction from the hot water supply means 8 to the second filter cup 12 in the state where the second filter cup 12 is placed in the second container 104, and therefore coffee extraction can be performed equally well even in the case of extraction with a small number of cups or extraction with a large number of cups.

Next, a ninth embodiment of the present invention will be described with reference to fig. 19 to 21. In the present embodiment, the upper and lower sides of each drawing are also defined as the upper and lower sides of the actual case. 111 is the coffee machine of the present invention. The coffee maker 111 includes a coffee maker main body 2, a container 3, and a filter bowl mechanism 112.

The coffee maker main body 2 includes an upright portion 5, a base portion 6, and a brim portion 7. The container 3 is placed on the base 6. A hot water injection mechanism 8 is disposed below the brim 7. The vertical positional relationship between the hot water injection mechanism 8 and the brim 7 is fixed.

The container 3 has a container body 9 having a bottom and an open top, and a handle 10 provided on a side of the container body 9. In addition, the container body 9 may be a glass container or a stainless steel vacuum double container.

The filter mechanism 112 has a first filter 113 for small-cup extraction (for example, for 1 to 3-cup extraction) and a second filter 114 for large-cup extraction (for example, for 4 to 6-cup extraction). The first bowl 113 has an extraction part 115 formed to be tapered downward, and a flange-like hanging part 116 provided at an upper end of the extraction part 115. On the other hand, the second bowl 114 has an extraction portion 117 formed to be tapered downward, a flange-shaped placement portion 118 provided below the extraction portion 117, and a support portion 119 for catching the hanging portion 116 of the first bowl 113. The support portion 119 is provided at an upper end portion of the extraction portion 117. In addition, the extraction part 115 of the first bowl 113 is formed smaller than the extraction part 117 of the second bowl 114. The first bowl 113 is configured to be attachable to the extraction portion 117 of the second bowl 114 by engaging the hook portion 116 with the support portion 119. In this way, when the first bowl 113 is attached to the second bowl 114, the second bowl 114 serves as the height adjustment portion 120 of the first bowl 113. The height of the upper end of the first bowl 113 attached to the second bowl 114 is equal to the height of the upper end of the second bowl 114. That is, in a state where the container 3 on which the bowl mechanism 112 is placed on the base 6, the vertical distance from the hot water injection mechanism 8 to the extraction unit 115 of the first bowl 113 is equal to the vertical distance from the hot water injection mechanism 8 to the extraction unit 117 of the second bowl 114, and the vertical distance from the brim 7 to the extraction unit 115 is equal to the vertical distance from the brim 7 to the extraction unit 117.

Next, the operation of the present embodiment will be explained. When a small number (for example, 1 to 3 cups) of coffee liquid is to be extracted, the second filter bowl 114 is placed on the container 3, and then the first filter bowl 113 is attached to the second filter bowl 114. In this case, the second bowl 114 serves as a height adjustment part 120 of the first bowl 113. The first filter bowl 113 is attached to the second filter bowl 114 (height adjuster 120) by engaging the hook 116 with the support 119 of the second filter bowl 114 (height adjuster 120). Then, a filter (not shown) having a size corresponding to the size of the extraction unit 115 is placed in the extraction unit 115, coffee powder is placed in the filter in an amount corresponding to the number of cups, and then the container 3 containing the first filter bowl 113 and the second filter bowl 114 (height adjustment unit 120) is placed on the base 6 of the coffee maker main body 2. Further, when the coffee maker 111 has a coffee grinder, after the first bowl 113 is placed in the coffee maker main body 2, coffee powder pulverized by the coffee grinder is transferred and stored in the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When coffee liquid of a large number (for example, 4 to 6 cups) is to be extracted, the second filter bowl 114 is placed on the container 3, a filter (not shown) having a size corresponding to the size of the extraction unit 117 is placed in the extraction unit 117, coffee powder of a number corresponding to the number of cups is put in the filter, and then the container 3 with the second filter bowl 114 mounted thereon is placed on the base 6 of the coffee maker main body 2. In this case, the second bowl 114 is a bowl having its original function. Further, when the coffee maker 111 has a coffee grinder, after the second bowl 114 is placed in the coffee maker body 2, coffee powder pulverized by the coffee grinder is transferred and stored into the filter. Then, hot water corresponding to the number of extraction cups is poured from the hot water pouring means 8 into the coffee powder in the filter. Thereby, a predetermined number of cups of coffee liquid are extracted from the coffee powder.

When the first bowl 113 is attached to the second bowl 114 serving as the height adjustment unit 120, the upper end of the extraction unit 115 of the first bowl 113 and the upper end of the extraction unit 117 of the second bowl 114 are at the same height, so that the distance in the vertical direction from the hot water injection mechanism 8 to the first bowl 113 is equal to the distance in the vertical direction from the hot water injection mechanism 8 to the second bowl 114. Accordingly, the positional relationship between the hot water injection mechanism 8 and the extraction unit 115 of the first bowl 113 and the positional relationship between the hot water injection mechanism 8 and the extraction unit 117 of the second bowl 114 are substantially the same. Therefore, the falling position or temperature drop of the poured hot water is substantially equal in the case of using the first bowl 113 and the second bowl 114, and therefore the coffee liquid can be extracted equally well. In the present embodiment, since the distance in the vertical direction from the brim 7 to the extraction portion 115 of the first filter cup 113 is equal to the distance in the vertical direction from the brim 7 to the extraction portion 117 of the second filter cup 114, it is possible to prevent coffee grounds from leaking between the first filter cup 113 and the brim 7 even when the coffee maker 111 has a coffee grinder, as in the case of using the second filter cup 114.

As described above, the present invention is the coffee maker 111 as follows: the coffee machine comprises a coffee machine body 2, a container 3, and a filter cup mechanism 112 arranged above the container 3, wherein hot water is injected from above the filter cup mechanism 112 by a hot water injection mechanism 8 arranged at a brim 7 of the coffee machine body 2, thereby extracting coffee liquid from coffee powder in the filter cup mechanism 112, the filter cup mechanism 112 has a first filter cup 113 for small cup count and a second filter cup 114 for large cup count, each filter cup 113, 114 has an extraction part 115, 117, and the second filter cup 114 also serves as a height adjustment part 120 of the first filter cup 113, thereby making the vertical distance from the hot water injection mechanism 8 to the first filter cup 113 when the first filter cup 113 is used appropriate, and coffee extraction at the time of small cup count can be performed well.

In the present invention, when the first bowl 113 and the second bowl 114 serving as the height adjustment portion 120 or the second bowl 114 serving as the bowl itself are placed on the container 3, the vertical distance from the hot water supply mechanism 8 to the first bowl 113 and the vertical distance from the hot water supply mechanism 8 to the second bowl 114 are equal, and therefore coffee extraction can be performed equally well even in the case of small-bowl extraction and in the case of large-bowl extraction.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example, although the embodiments described above are directed to placing the container on the base of the coffee maker main body, the embodiments can also be applied to a coffee maker of a type in which extraction is performed in a state in which the container is placed on a table or the like. In the above embodiments, the number of the filter cups is two, that is, the number of the small cups and the number of the large cups, but three, that is, the number of the small cups, the number of the medium cups and the number of the large cups, or the type corresponding to the number of the large cups may be provided. Similarly, in the eighth embodiment, three or more kinds of containers may be provided.
