DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small and simple coffee maker having a function of a coffee mill for grinding coffee beans and a dripper for filtering coffee powder.

[0002]

2. Description of the Related Art A coffee mill has a handle, which is manually operated by turning the handle to manually rotate a mortar to grind coffee beans, and a coffee mill which rotates a cutter at high speed by electric power. There is an electric type that pulverizes beans finely.

FIG. 4 shows an example of an electric system, in which a pulverizing chamber 2 having a lid 7 is formed in an upper half of a synthetic resin main body 1, and a driving mechanism such as a motor is provided in a lower half of the main body 1. 5, a drive shaft 4 from the drive mechanism 5 is protruded from the pulverizing chamber 2, and a thin cutter 3 having both ends bent at the end is provided. The lid 7 may be formed transparent so that the inside can be viewed. In the figure, reference numeral 6 denotes a power switch of the drive mechanism 5, and this example shows a case where the power switch is connected to a commercial power supply by a cord 8.

When the coffee beans are put into the grinding chamber 2 by removing the lid 7 and the lid 7 is closed and the switch 6 is turned on, the cutter 3 is rotated at high speed by the driving mechanism 5 to grind the coffee beans. . Then, the pulverizing state of the coffee beans is checked by looking into the pulverizing chamber 2 from above the lid 7, and when the pulverized coffee beans are pulverized to an appropriate roughness, the switch 6 is turned off and the cutter 3 is stopped.
The lid 7 is removed again to take out the ground coffee powder. This is the use as a coffee mill, the obtained coffee powder drip in a different way than this coffee mill.

There are various drip methods such as a siphon and a filter. For example, in the case of a filter, the filter is set in a filter container, and the filter container is mounted on a drink cup, and the coffee powder is stored in the filter. Pour hot water and strain to make coffee.

[0006]

The coffee mill shown in FIG. 4 is itself a small, handy type machine.
In particular, if the power is obtained from batteries etc., the size becomes smaller, and to obtain several cups of coffee at once, it is easy to use without taking up space as a device, but the drip is another dripper It must be performed, and it takes time to transfer coffee powder to the dripper.

[0007] Further, there is a problem in terms of cleaning, and in the conventional coffee mill, it is troublesome to clean and wipe off the coffee powder scattered in the crushing chamber 2. Particularly, the bottom of the crushing chamber 2 and the back side of the cutter 3 were unsanitary because it was difficult to remove the coffee powder because they were close to each other.

[0008] As a coffee maker, there is also a coffee maker in which a coffee mill and a dripper are integrally mounted.
Coffee is automatically made just by setting water and coffee beans.However, any equipment such as incorporating a water tank and a heater for water heater on the support base is large, requiring an installation place, It is inconvenient to use containers and filters.

An object of the present invention is to eliminate the disadvantages of the prior art and to carry out both milling and drip on the premise that it is a handy type and compact, saving the time and effort of cleaning. It is to provide an easy simple coffee maker.

[0010]

According to the present invention, in order to achieve the above object, firstly, a cutter shaft having a built-in drive mechanism and having a cutter at a tip thereof is protruded downward from a bottom surface, and the cutter shaft is attached to the shaft. An upper body provided with a wiper that rotates about the center to wipe the bottom surface of the upper body, and a cutter for the upper body when the upper body is stacked when the upper body is stacked and the upper body is opened and coffee beans are charged. Composed with a container-shaped lower body with a shaft inserted and a lower end closed by a net, the lower body can be placed on a beverage cup, and a filter paper can be detachably inserted under a metal filter. Secondly, the bottom of the upper body is formed in a conical shape, and thirdly, a loop for holding the filter paper is fitted to the lower end of the lower body.

According to the first aspect of the present invention, the upper body and the lower body which are stacked on each other are combined, and even if these two are combined, the size is the same as that of a conventional handy type coffee mill. It is small and easy to handle.

Also, put the coffee beans in the lower body,
When the upper body and the lower body are overlapped, the cutter shaft is inserted into the lower body. Thus, the cutter at the tip of the cutter shaft is rotated by the driving mechanism, and the coffee beans are pulverized. And the coffee powder ground by the cutter naturally accumulates below the lower body. If the metal filter on the lower end face of the lower body is covered with filter paper in advance, the ground coffee does not leak.

[0013] Then, if only the lower body is placed on the beverage cup and hot water is poured into the lower body, the metal filter and the filter paper become a filter and drip coffee.

On the other hand, since the bottom surface of the upper body can be automatically wiped by the wiper, there is no need to separately clean this portion. After that, since the cutter shaft only protrudes downward from the bottom surface of the upper body, cleaning becomes easy.

According to the second aspect of the present invention,
By forming the bottom surface of the upper body in a conical shape, it is possible to prevent coffee powder from adhering.

According to the third aspect of the present invention, the filter paper can be easily and firmly attached and detached by fitting the loop body to the lower end of the lower body and holding the filter paper with the ring body. If you use the kitchen paper that most kitchens have, you can use it easily.
