Since it is disposed radially about the central axis (C1) of the vessel 120, there is an advantage that the water flowing in the branch pipe 40 is not accelerated by gravity, the third vessel 30 of There is an advantage that the water can be sprayed evenly over a large area above the coffee powder (C) stored inside.
- the drip coffee maker 200 includes a cleaning hole 41 which is a hole formed in the distal end of the branch pipe 40, and a stopper 42 that detachably closes the cleaning hole 41. Therefore, there is an advantage that the internal cleaning of the branch pipe 40 is convenient through the cleaning hole 41 after removing the stopper 42.
- the drip coffee maker 200 is a tubular member disposed to surround the periphery of the second through hole 21, and the guide member 43 protrudes from the lower surface of the branch pipe 40 by a predetermined length. ), The water discharged from the second through hole 21 is prevented from flowing to the left and right along the outer circumferential surface of the branch pipe 40, and can be guided to fall only downward have.
- FIG. 14 shows a second container 20 of a drip coffee maker, which is a third embodiment of the present invention.
- the second container 20 of FIG. 14 has the same configuration as most of the second container 20 of the drip coffee maker 100, except that the internal space is separated by the space separating means. Only the differences between are described.
- the second container 20 shown in FIG. 14 has a vertical pipe-shaped vertical blocking wall 25 having both ends opened therein as the space separating means, thereby providing an internal space of the second container 20. It has a double container structure that divides it into a center part and an outer part.
- the vertical blocking wall 25 is a circular pipe extending along a central axis C1 of the side portion 22 by a predetermined length, and the inner diameter thereof is smaller than the inner diameter of the side portion 22. It has a shape concentric with the side portion (22).
- the lower end portion of the vertical blocking wall 25 is arranged so as to surround the second through holes 21 in the center of the second through holes 21 in a watertight manner.
- the lower end of the vertical blocking wall 25 is watertightly coupled to the bottom 23, and the upper end of the vertical blocking wall 25 is open.
- the upper end of the vertical blocking wall 25 is formed to have a lower height than the upper end of the side surface portion 22, so that water contained in the vertical blocking wall 25 flows into the interior of the side surface portion 22. It has a structure that can
- the water supplied from the first vessel 10 is first accommodated in the internal space of the vertical blocking wall 25 and has a sufficient flow rate q1 per unit time discharged through the first through hole 11. In this case, as time passes, it may flow into the space between the vertical barrier wall 25 and the side portion 22.
- the second through hole belonging to the cross-sectional area of the vertical blocking wall 25 among the second through holes 21 formed in the bottom portion 23 is used.
- water is discharged through the first through the second through holes 21 through the second through holes 21 formed in the bottom portion 23 of the space between the vertical blocking wall 25 and the side portion 22. Since water is discharged, first, water is first supplied to the center portion of the third container 30, and then water is supplied to an outer portion of the third container 30 later.
- FIG. 15 shows a second container 20 of the drip coffee maker, which is a fourth embodiment of the present invention.
- the second container 20 of FIG. 15 has the same configuration as most of the second container 20 of the drip coffee maker 100, except that the internal space is separated by the space separating means. Only the differences between are described.
- the said 2nd container 20 shown in FIG. 15 has a double container structure by providing the horizontal flat wall 26 of circular flat shape arrange
- the horizontal blocking wall 26 is a circular flat plate member having the center axis C1 of the side portion 22 as the center of the circle, and its inner diameter is the same as the inner diameter of the side portion 22.
- the outer circumferential surface of the horizontal blocking wall 26 is watertightly coupled to the inner circumferential surface of the side portion 22, thereby dividing the inner space of the second container 20 up and down.
- the water supplied from the first container 10 is primarily formed by the side portion 22 and the horizontal barrier wall 26. It is accommodated in the upper inner space of the (20), and after a predetermined time flows into the lower inner space of the second container 20 formed by the side portion 22 and the bottom portion 23, When the same amount of water is used, the time taken for the water to be completely discharged through the second through hole 21 is increased, so that an additional "moistening effect" occurs.
