Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric coffee brewer in which the concentration of extracted coffee liquid can be adjusted.

Conventional technology Conventionally, this type of electric coffee boiler was developed by, for example,
As shown in Japanese Patent No. 59-40038, there is provided a canopy of a container having a hot water outlet, a coffee basket that is detachably attached to the lower surface of the canopy and receives hot water to extract coffee liquid, and It is generally known that the lid body is placed on the coffee basket and includes a lid body that adjusts the amount of hot water poured into the filter in the coffee basket from the discharge port.

Problems that the invention aims to solve By the way, in conventional electric coffee boilers of this type, the hot water flow rate adjustment mechanism is provided at a position offset from the center of the lid toward the outer diameter, so hot water is not placed in the center of the lid. It is not possible to adequately adjust the amount of hot water by simply discharging hot water, and a mechanism for dispersing hot water must be provided in the eaves.

However, in an electric coffee boiler that has a structure in which the coffee basket is attached to and removed from the main body case from above, it is not possible to provide a canopy, so it is not easy to provide a hot water diffusion mechanism at the hot water outlet. Even if it could be provided, there would be problems in that the structure would be complicated and cleaning performance would be poor.

Means for Solving the Problems The present invention was made to solve the above problems, and includes forming a plurality of guide grooves and drip holes for hot water poured from a protruding pipe in the lid body, while A plurality of flow holes for the hot water and a water diversion section for opening and closing the guide groove are formed in a hot water receiver rotatably mounted on the lid.

By doing this, the hot water discharged from the discharge pipe is received by the diffuser plate and the hot water receiver attached to the top surface of the lid, and the coffee is poured from the flow hole formed in the hot water receiver through the drip hole formed in the lid. Diffuse hot water into the basket. On the other hand, the hot water guide groove formed in the lid body is opened and closed by the water dividing portion formed in the hot water receiver to change the dripping state of the hot water into the coffee basket.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 1 is a coffee bean mill. A cutter 3 rotated by a motor 2 is disposed within the mill section 1 and is adapted to grind coffee beans. Further, a mill net 4 is provided on the circumferential surface of the mill section 1 to guide coffee powder obtained by pulverization to a coffee basket 5. A heater 7 heats the water in the water tank 6 to make it hot water, and this hot water is supplied into the coffee basket 5 from a hot water discharge pipe 8. A coffee cup 9 stores the coffee liquid extracted in the coffee basket 5, and is located below the coffee basket 5. As shown in FIG. 3, a paper filter 10 for storing coffee powder is placed inside the coffee basket 5.
Further, as shown in FIG. 2, an engagement piece 13 is provided on the outer circumferential surface of the upper end of the coffee basket 5 and is detachably engaged with the engagement recess 12 of the main body case 11 from above. Furthermore, a removable lid 14 is attached to the upper end of the coffee basket 5 and has the function of diffusing the hot water discharged from the discharge pipe 8 to the center of the coffee basket 5 and adjusting the concentration of the extracted coffee liquid. ing. As shown in FIG.
a, 18b, 18c are formed, and the hot water guide grooves 16a, 16b, 16c are formed with the drip holes 18a, 18b, 18c as boundaries, and a cylindrical raised part is partially cut off. 17 are erected to surround each drip hole 18a, 18b, 18c. Reference numeral 20 denotes a hot water receptacle, which is rotatably attached to the lid 14 by screws so as to fit inside the upright part 17, and opens and closes each drip hole 18a, 18b, 18c as shown in FIG. Water division parts 19a, 19b, 19c and each drip hole 18a, 1
Flow holes 15a, 15b facing 8b, 18c,
15c are formed respectively. Reference numeral 23 denotes a hot water diffusion plate having a spherical central portion, which is integrally formed with the hot water receiver 20, and surrounded by the flow holes 15a, 15.
b, 15c are located. Further, the guide groove 1
6a, 16b have hot water guide channels 21a, 21b extending radially toward the outside of the lid 14, and the filter 10 and the coffee flow from the respective ends 22a, 22b of the guide channels 21a, 21b. Hot water is dripped into the gap between the baskets 5.

The operation of this embodiment configured as above will be described.

First, when brewing regular coffee, the hot water receiver 20 is rotated as shown in FIG.
Align the drip holes 18a, 18b, 18c of 4, and guide grooves 16a, 1
6b and 16c are closed. By doing this, the hot water discharged from the discharge pipe 8 will be transferred to the hot water receiver 2.
It is evenly diffused by the diffusion plate 23 attached to the central part of
a, 18b, and 18c directly fall into the coffee grounds in the filter 10 set in the coffee basket 5, extract coffee liquid, and collect it in the coffee cup 9.

Next, when brewing American coffee, rotate the hot water receiver 20 as shown in FIG.
If you move it to 8a, 18b, 18c side, guide groove 1
6a, 16b, and 16c are opened. Therefore, the hot water discharged from the discharge pipe 8 is transferred to the hot water receiver 2 as described above.
It is evenly diffused by the diffusion plate 23 at the center of the flow hole 1.
5a, 15b, 15c and guide grooves 16a, 16b,
16c. Downstream hole 15a, 1
The hot water diverted to 5b and 15c is dripped through the drip hole 18a,
It is dripped onto the coffee grounds in the filter 10 via 18b and 18c. On the other hand, the guide grooves 16a, 16b
The hot water separated into the filter 10 passes through the guide channels 21a and 21b from the channel ends 22a and 22b.
The liquid is dropped into the gap between the coffee basket 5, mixed with the coffee liquid extracted from the coffee powder below the coffee basket 5, and dropped into the coffee cup 9. As a result, you will get a weaker American coffee.

Effects of the invention As described above, according to the invention, the boiling water receiver, which is rotatably attached to the lid body, is rotated to separate the hot water, making it possible to easily adjust the concentration of coffee with a simple structure. We can provide a boiler.
