Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a coffee boiler that supplies hot water to ground coffee inside the basket through a drip hole in a lid that serves to open an upper surface of the basket.

(b) Conventional technology As shown in Japanese Utility Model Publication No. 56-37475, in the past, when obtaining black tea liquid of normal strength, hot water was evenly supplied to the surface of the black tea through the diffusion holes in the cylindrical part. By doing this, when obtaining a mild black tea liquid with a slightly weak taste, the boiling water is dripped directly onto the filter paper using multiple gutter and dripped from the above-mentioned diffusion hole to the black tea liquid after passing through the black tea. It was obtained by mixing.

However, with such a configuration, it is particularly difficult to mix the hot water dripped onto the filter paper and the black tea liquid that has passed through the black tea to obtain a suitably mild black tea liquid. Even if it is mixed with black tea liquid, the ingredients are different from each other, and the desired mild black tea liquid cannot be obtained.

(c) Problems to be Solved by the Invention The present invention was accomplished in order to solve the above-mentioned drawbacks, and provides a coffee boiler that can easily produce mild and regular coffee liquid.

(d) Means for Solving the Problems The present invention forms a recess surrounded by a jetty in the approximate center of the lid that closes the top opening of the Basquera i for storing coffee powder, and also forms a recess around the outer periphery of the lid. An annular groove is formed, an internal drip hole is formed in the recess, and a plurality of drip holes are formed at intervals in the groove, and the groove is opposite to the tip opening of the discharge pipe for discharging hot water. A cutout opening that communicates the recess and the groove is formed in the jetty, and the cutout opening is opened and closed by an externally operable switching body, and when the cutout opening is closed, hot water is poured into the coffee powder from the external drip hole. The coffee powder is supplied to the entire upper surface, and when opened, the coffee powder is supplied from the internal drip hole toward the center of the upper surface.

(e) When the notch opening is closed by the action switching body, hot water is evenly supplied from the external dripping hole to the entire area on the coffee grounds to obtain eregular coffee liquid, and when the notch opening is opened, the hot water is dripped inside. The coffee liquid can be intensively supplied from the holes onto the coffee grounds, resulting in a mild coffee liquid with a weak taste.

(1) Example (1) is a plate-shaped heating body with a heater (not shown) inside, (2) is a decanter that can be attached and detached from the top surface of this heating body (1), and (3) is a plate-shaped heating body that has an open top surface. water tank, (4)
Although not shown, numeral 5 indicates a basket disposed in the main body of the coffee boiler, and numeral 5 indicates a bean grinding case integrally formed with the basket 4. Said basket (
In 4), a through hole (6) is bored in the bottom surface and a lid 7) is provided in the top opening. The bean crushing case (5) is provided with a cutter (9) that is rotated by a drive morph (8), and a metal filter (10) that communicates with the basket (4) is fitted into the side surface. (
11) is a timer motor that drives the drive motor (8) for a predetermined time and then energizes the heater.

(12) is a setting knob. (13) is a scene set valve provided at the bottom of the basket (4) to open and close the through hole (6). This pulp (13) can be rotated by the lid (14) of the decanter (2).

A recess (16) surrounded by a jetty (15) is formed in the center of the lid (7), and an annular groove (17) is formed around the outer periphery of the recess (16). This groove (1
7) are provided with external drip holes (18) at intervals, and also have linear communication grooves (19) formed therein.

The recess (16) has a rotating portion (20) with a mouth-shaped cross section.
a) and a long operating section (20b).
0) is rotatably provided. There is a shaft hole 22) in the center of this recess (16) and a pair of elongated holes (23) of appropriate length around it.
(23) respectively, and the switching body (20) has an open part (24) on its side surface and a shaft part (25) inserted into the shaft hole (22) and formed with a plurality of slits (25) in the vertical direction. 26) and the locking portions (27) (2) inserted into the elongated holes (23) (23).
7) respectively. The jetty (15) is formed with a cutout opening (30) that opens toward the communication groove (19). In addition, the slit (25) and the elongated hole (23) (
23) constitute an internal drip hole. (32) is a paper filter.

The top opening of the bean crushing case (5) is a rotating lid (35).
The - side of this rotating lid (35) has pins (36) (36) on the top surface of the lid (7).
The coffee powder can be freely rotated through the basket (
4) A curved surface portion (35a) is formed to facilitate uniform guidance.

(40) has one end connected to the water tank (3) via the check valve (41).
), its middle part is wrapped around the heating element (1), and the other end is opened so as to face the notch opening (30) of the lid (7).

With such a configuration, in order to obtain a mild coffee liquid with a weak taste, as shown in FIG. )
The elongated hole (23) (23) and the slotted throat (2) guide the hot water that can be discharged directly into the recess (16) and serve as an internal drip hole.
From 5), this hot water is concentratedly dripped onto the center of the upper surface of the coffee grounds (G), and a hot water path is formed in the center of the coffee grounds (G) to allow the hot water to pass through quickly. be.

In order to obtain regular coffee liquid, the switching body (20) is rotated to close the notch opening (30), and the hot water from the discharge pipe (40) is guided to the groove (17). The coffee powder (G) is uniformly supplied to the entire upper surface of the coffee powder (G) from the external drip holes (18).

(G) Effects of the Invention The present invention makes it possible to reliably switch the hot water to the internal drip hole or the external drip hole using the switching body, and collects the hot water in the center of the coffee powder to obtain a mild coffee liquid and spread it over the entire surface. Can be dispersed to obtain regular coffee liquid,
Moreover, the switching operation becomes extremely simple.
