Description

Detailed Description of the Invention The present invention has a function of pulverizing raw materials such as coffee beans placed in a basket, and a function of dropping boiling water into the basket and filtering the liquid extracted from the pulverized raw materials with a filter. This invention relates to a beverage manufacturing machine that also has the functions of

Conventionally, this type of beverage manufacturing machine has a basket for storing raw materials such as coffee beans, a filter installed in the opening at the bottom of the basket, a saucer attached to the bottom of the filter, and a socket directly below the pouring spout of the saucer. A container placed in the container, a crushing body housed in the basket, a motor for driving the crushing body, a water tank containing a desired amount of water, and a heating means to heat the water supplied from the water tank and place it inside the basket. It consists of a water heater that supplies hot water.

In the conventional example configured in this way, first, raw materials, such as coffee beans, are placed in the basket, and then,
The motor is rotated and the coffee beans are ground by the grinding body, and when the coffee beans are ground to an appropriate size, the motor is stopped. Next, the heating means is energized, the hot water heated by the heating means is dripped directly onto the ground coffee beans in the basket, and the components are extracted from the ground coffee beans and filtered with a filter. The extract collected in the saucer is placed in a container. By the way, if the coffee beans are ground too finely, the filter will become clogged during extraction, and the ground coffee beans and coffee extract will overflow from the basket, staining the basket, its peripheral equipment, the dining table, etc. It was hot.

Furthermore, since the liquid level rises during extraction, the diameter of the basket must be large in order to ensure the filtration area of the filter, and due to processing problems, a flat filter is the simplest. However, during pulverization, the size of the pulverizer is better if it has a smaller diameter with less imbalance, and the smaller the size, the easier it is to clean afterwards. Furthermore, since the bottom shape is flat,
Since coffee beans are not stirred smoothly during grinding, only particles with non-uniform particle size can be obtained.

The present invention solves the above-mentioned conventional drawbacks, and embodiments of the present invention will be described below with reference to the drawings.

It protrudes from the mounting stand 30.

In this embodiment configured as described above, first, the engagement protrusion 4 of the saucer 1 is fitted into the engagement groove 7 of the basket 6, and the saucer 1 is attached to the lower part of the basket 6.
An appropriate amount of coffee beans is put into a basket 6 partitioned by a filter 15, and a basket lid 9 is attached to the upper opening of the basket 6. And saucer 1
Then, the basket 6 with the basket lid 9 attached is placed on the basket mounting table 30 as shown in FIG. With,
A desired amount of water is poured into the water tank 28 and the lid 39 is closed. Further, on the heating body 32, there is a spout 3 of the saucer 1.
The container 23 is placed as shown in FIG. 1 so that the container 23 and the socket 24 of the container 23 face each other. Next, the motor 40 is energized, and the crushing blades 22 of the motor 40 are
is rotated, and the coffee beans in the basket 6 are crushed by the crushing blades 22 until they become a suitable size. By the way, the ground coffee beans flow inside the basket 6 and some of them scatter toward the outside of the basket 6, but the basket lid 9 prevents them from scattering. Further, the flowing coffee beans are further agitated by the protrusion 53 of the basket 8 to become coffee powder of uniform particle size. Then, when the motor 40 is de-energized and the sheathed heater 33 is energized, the water supplied from the water tank 28 to the heating pipe 34 via the water supply pipe 35 is heated by the sheathed heater 33, and the heating pipe The hot water boiled at 34 is pushed up from the heating pipe 34 to the hot water supply pipe 37 by the action of the check valve 36 and the steam pressure, and is then poured into the hot water receiving tray 11 from the injection pipe 38. The hot water poured into the hot water saucer 11 is evenly poured over the ground coffee beans from the drip hole 12, and as it passes through the ground coffee beans, the components of the coffee beans are absorbed. Extract. and,
The hot water from which the coffee components have been extracted is filtered by a filter 15, collected in a saucer 1, further filtered by a fine second filter 51, and then passed through a heating element 32.
The container 23 is housed in a container 23 that is kept warm. However, if the coffee beans are ground too small, the ground coffee beans will block the holes in the filter 15 and reduce the filtering ability of the filter 15, which will gradually increase the amount of liquid in the basket 6 and cause the coffee powder to The contained extract flows from inside the basket 6 through the air hole 10 and drip hole 12 onto the basket lid 9, flows out from the upper end opening 8a of the overflow hole 8, is further filtered by the second filter 51, and becomes clear coffee. It becomes a liquid and is stored in the container 23.

As described above, according to the present invention, there is provided a saucer which receives the extract extracted by the hot water supplied to the basket and passed through the filter, has a spout, and is integrally provided with a handle; The basket is provided with a container for receiving the dripped extract liquid, an opening for overflow is formed in the basket, and a protrusion protruding inward is provided on the outer peripheral wall of the basket, and the protrusion is covered by the handle of the saucer. , an overflow channel is formed to guide overflow water from the overflow opening into the container, and with this configuration, during grinding, the flowing coffee beans are further stirred by the inwardly protruding protrusions to achieve a finer particle size. It is possible to obtain uniform coffee powder and a delicious coffee liquid, and at the time of extraction, the extract overflowing from the basket can be stored in the container through the overflow channel, so that the peripheral equipment of the basket,
It will not stain the dining table etc. Furthermore, since the overflow path is formed by covering the protrusion that protrudes inward from the basket with the handle of the saucer, cleaning the overflow path is easy and there is no outward protrusion. Therefore, the device has excellent effects such as being compact and easy to handle.
