 Disclosure of the invention

 Problems to be solved by the invention

[0004] However, the above-described conventional technology has the following problems. It is a problem that the hot water protruding hole force applied to the hot water supply nozzle does not come out uniformly. When a large amount of hot water is supplied, the amount of hot water that accumulates inside the hot water supply nozzle is small and the amount of hot water that exits from the hot water protruding hole is small, so that it is difficult to cause a problem. However, when the amount of hot water supply is small, the amount of hot water coming out of the hot water projection hole is larger, so that almost no hot water is accumulated inside the hot water supply nozzle, and hot water is likely to come out unevenly.

[0005] In particular, in the case of a home coffee brewing apparatus, in order to produce a delicious coffee beverage, it is necessary to gradually supply a small amount of hot water enough to steam coffee powder. Therefore, the amount of hot water passing through the hot water nozzle is inevitably reduced. For this reason, hot water tends to come out unevenly from the holes made in the hot water nozzle. However, under the uneven protrusion of hot water, it is not possible to create an environment in which the coffee powder is uniformly steamed, making a delicious coffee drink. It ’s difficult. This is not limited to coffee, but the same can be said for other beverages such as tea.

Next, after the hot water fills the recess, the overflowing hot water comes out of the hot water pouring hole. Therefore, a more uniform amount of hot water can be discharged from each hot water pouring hole.

 [0013] Another aspect of the present invention is a beverage extraction apparatus for extracting a beverage by supplying hot water to a beverage extraction powder, the hot water supply nozzle supplying hot water toward the beverage extraction powder, It is provided along the outer periphery of the outer portion or the bottom inner periphery thereof, and is provided in a plurality of hot water pouring holes for pouring hot water and in the hot water supply nozzle, on the center side of the hot water nozzle from the hot water pouring hole. Thus, the beverage extractor is provided with a protrusion for lowering hot water toward the hot water pouring hole and a hot water supply port for supplying hot water toward the top of the protrusion.

 [0014] By using the hot water nozzle having such a structure, the hot water that has entered the hot water nozzle first contacts the top of the protruding portion. Next, the hot water also passes through the slope through the hot water pouring hole located at the base of the slope. For this reason, a uniform amount of hot water comes out from each of the hot water pouring holes. Therefore, hot water can be uniformly supplied to a solid such as coffee powder below the hot water nozzle, and a uniform beverage can be extracted without unevenness depending on the location.

 [0015] Another aspect of the present invention is a beverage extraction apparatus for extracting a beverage by supplying hot water to a beverage extraction powder, the hot water supply nozzle supplying hot water toward the beverage extraction powder, It is provided along the outer periphery of the outer portion or the bottom inner periphery thereof, and is provided in a plurality of hot water pouring holes for pouring hot water and in the hot water supply nozzle, on the center side of the hot water nozzle from the hot water pouring hole.

Head to hole 22. Since the amount of hot water passing through each concave passage 25 can be made uniform regardless of where the hot water is supplied on the concave surface 26, the amount of hot water coming out of the hot water pouring hole 22 can be made more uniform. wear.

 Next, a process of extracting a coffee beverage using the beverage extraction device 1 according to the first embodiment will be described based on FIGS. 1 to 6.

 [0037] First, a user operation will be described. Open the container cover 40 and set a filter (not shown) inside the extraction container 4. Next, coffee powder is put on the filter, and the container cover 40 is closed. Next, the tank cover 10 is opened and water is poured into the area 3 a in the water supply tank 3. When the water is filled, close the tank cover 10 and turn on the switch 60.

 [0038] Next, the operation of the beverage extraction device 1 after the switch 60 is turned on will be described. When the switch 60 is turned on, the heater 71 is energized while the water in the water supply tank 3 fills the tube 70. Then, the water in the tube 70 is warmed to become hot water. Then, the hot water ascends the tube 15 force vertical tube 16a and reaches the horizontal tube 16b. The hot water in the horizontal tube 16b passes through the hot water supply port 19 from the hole 17 and enters the hot water supply nozzle 18. Hot water that has entered the hot water supply nozzle 18 falls to the top 21 and is guided to each hot water pouring hole 22 through each concave path 25. The hot water from each hot water pouring hole 22 falls onto the coffee powder on the filter until the water in the water supply tank 3 runs out. The coffee powder containing hot water becomes steamed and the coffee beverage is extracted. The extracted coffee beverage falls into the beverage pot 5.

 When the hot water supply nozzle 18 shown in FIG. 6 is used, the hot water flow force after the hot water passes through the hot water supply port 19 is different from the above-described flow.

When the concave surface 26 is filled with hot water, its surrounding force also overflows and passes through each concave path 25 to each hot water pouring hole 22. The hot water coming out of each hot water pouring hole 22 falls on the coffee powder on the filter until the water in the water supply tank 3 runs out. The coffee powder containing hot water becomes steamed and the coffee beverage is extracted. The extracted coffee beverage falls into the beverage pot 5.

 [0041] When the hot water supply nozzle 18 having the above-described structure is used, the hot water that has entered the hot water supply nozzle 18 exits from the hot water pouring holes 22 through the slopes 23 from the top portion 21. Since each slope 23 has substantially the same inclination angle, the amount of hot water passing through each slope 23 can be made almost uniform, and as a result, the amount of hot water flowing out from each hot water pouring hole 22 can be reduced. It can be made uniform. In particular, since the concave path 25 is provided on each slope 23, the hot water passing through each concave path 25 is difficult to merge with the hot water passing through the adjacent concave path 25. For this reason, the hot water divided almost uniformly into each concave path goes to each hot water pouring hole 22 while maintaining the amount thereof. Therefore, the hot water can be discharged more uniformly from each hot water pouring hole 22.

 [0042] When the hot water supply nozzle 18 having the concave surface 26 is adopted, the hot water fills the concave surface 26, and then the overflowing hot water passes through the slopes 23 from the hot water pouring holes 22. Get out. Even if hot water is supplied to any place on the concave surface 26, the amount of hot water passing through each concave passage 25 can be made uniform. Can do.
