Description

[Detailed description of the invention] This invention relates to a coffee boiler with a mill that integrates a coffee boiler and a mortar-type coffee grinder, which is simple and economical in construction, and which makes the operation of grinding coffee powder simple and reliable. This is what I am trying to do.

Conventionally, there was a mortar-type coffee boiler with a mill that guided the ground powder directly into the coffee basket, but when hot water was dripped onto the coffee grounds, steam entered the mill through the inlet for the coffee grounds. However, there is a drawback that the powder and coffee beans present at the inlet become wet, and in order to solve this problem, a means for sealing the inlet for coffee grounds is required, which is complicated and costly, and is a perfect sealing method. The problem of steam infiltration remained unresolved.

From these viewpoints, the present invention integrates the coffee boiling function and the coffee grinding function while keeping them independent, thereby reducing the overall cost and facilitating the grinding operation.

The stopper 33 is biased by a spring 34 in the projecting direction so as to be freely retractable and engages with a chevron-shaped projection 35 provided on the bottom surface of the powder container 27. inlet 30 of
and the detection port 26 are brought into close contact with each other.

36 is a cover lid of the bean container 22, and 37 is a lid of the container 3.

38 is a switch knob, which has a motor contact S1 that is electrically connected to the motor 18 as shown in the electric circuit shown in FIG. The switch SW provided with the switch SW can be operated.

A pilot lamp 41 lights up when the heating element contact S2 is connected.

In addition, the attachment/detachment insertion port 42 of the powder container 27 and the switch knob 3
8. The pilot lamp 41 is formed on the same surface of the main body 1.

The bean container 22, fixed mill stand, fixed mill 24, movable mill 21. Motor 18, detection port 26, powder container 27. The powder container lid 31 forms a coffee mill section.

In the above configuration, the operation thereof will be explained next.

When coffee beans are placed in the bean container 22, they pass through the through holes 25' and 24' of the fixed mill stand 25 and the fixed mill 24.

When the switch knob 38 is turned to the motor contact S1 side, the movable mill 21 rotates as the motor 18 starts rotating, and the coffee beans are crushed and the coffee powder blown away by centrifugal force is sent from the detection port 26 to the inflow port 30 to the powder container 27. Accumulate inside.

Note that since the bottom surface 23 of the bean container 22 is inclined, coffee beans are sequentially supplied to the fixed mill 24 and the movable mill 21.

Further, a chevron-shaped umbrella 43 is provided on the top of the fixed mill stand 25 to prevent the ground coffee beans from flying out in the E direction.

When the switch knob 38 is operated again and the motor contact S1 is opened, the motor 18 is stopped and the crushing is completed.

The ground coffee powder is pulled out in the direction opposite to arrow A by holding the powder container handle 32.

At this time, the stopper 33 is moved downward by the protrusion 35.

Next, a filter 44 is placed in the basket 12, coffee powder 45 is placed in the filter, and the basket 12 is stacked in the coffee container 15 and placed on the heat insulating plate 6.

When the water tank 8 is filled with water and the switch knob 38 is operated to connect the heating element contact S2, power is supplied to the heating element 17 and the check valve 1
The water in the heating pipe 11 is heated through the heating body 7.

The heated water generates steam and bubbles, expands, ascends the water rising pipe 14, drops onto the coffee powder 45 from the discharge port 13, and the coffee liquid filtered by the filter 44 is collected in the coffee container 15.

Note that the check valve 10 allows water to pass from the spout 9 to the heating pipe 11, but not the other way around, so that the water is heated as described above and hot water is successively supplied to the coffee grounds 45.

When all the water in the water tank 8 runs out, the temperature of the heating element 7 rises rapidly, which is sensed and a thermostat (not shown) is activated to keep the heating element 7 at a constant temperature.

That is, since the coffee container 15 is heated by the heating element 7 via the heat insulating plate 6, the finished coffee liquid is kept at a constant temperature.

As is clear from the above explanation, in the present invention, the coffee mill part that grinds coffee beans and the coffee boiler part that makes coffee liquid are incorporated into the main body consisting of a base and a container, and one side where the powder container is stored is open. The box-shaped powder container storage part is formed by the concave part of the container that forms the water tank and the bean container, so the number of parts is small, and both the container and the bean container can be processed using a resin mold that moves in one direction. Therefore, manufacturing is easy and costs are low.

In this method, as shown in Fig. 5, a bean container part 2 is attached to a base 2'.
2' and a water tank part 8' are integrally formed into a container 3',
A box-shaped recess 28' with an open front and lower surface is provided, and a box-shaped powder container 27 with an open front is provided between the base 2' and the container 3'.
A similar effect can be obtained by forming a powder container storage section 29' for storing the powder container.

Furthermore, since the attachment/detachment insertion opening for the powder container storage section is formed in the main body on the same level as the switch knob, it is convenient to grind coffee beans and boil coffee while the main body remains stationary.

The main body is a combination of the container and base, creating a U-shape, and the coffee container can be placed in this space in a removable manner.
This coffee container can also be operated from the same direction as the opening.

Further, as shown in FIGS. 3 and 4, the coffee bean container 22 is detachably attached to the main body 1 by a fixed mill stand 25 having a fixed mill 24, so that the fixed mill 24. The movable mill 21 is easy to clean, and the powder container storage section 29
It also has the effect of making cleaning easier.

Furthermore, since the powder container storage section 29 is formed into a box shape with one side open, it has the effect of preventing the coffee powder ground by the mill from scattering outside the main body 1.
