Description

[Detailed description of the invention] This invention is a coffee grinder that can be used both as a coffee grinder for grinding coffee beans and as a coffee grinder for brewing coffee by pouring boiling water into the ground coffee powder. This relates to preserving the freshness of beans stored in a container.

Generally, coffee is made by grinding coffee beans, placing the ground coffee beans on a recyclable filter such as cloth paper, pouring boiling water over this, brewing, and filtering through the filter to extract the coffee liquid. However, in the past, coffee grinders for grinding coffee beans and coffee making machines for making coffee by pouring boiling water over ground coffee powder were manufactured and sold separately, so these devices were not used. When making coffee using a coffee grinder, the ground coffee powder had to be transferred to a coffee grinder container.

A variety of conventional coffee grinders are manufactured and sold, but all of them have a grinding time that allows them to perform all coffee filtration methods (siphon type, percolator, manual cloth drip, paper hole drip, etc.). Since most types have methods of adjusting the length and roughness of the powder, it is generally difficult to grind in a way that is compatible with the filtration method, and it is difficult to provide delicious coffee.

Furthermore, when purchasing coffee powder to make coffee, the freshness of the coffee powder is said to be about one week, whereas the freshness of coffee beans is about one month, which is a big difference in the shelf life.

For this reason, there has recently been a growing tendency to grind coffee beans at home in order to easily obtain delicious coffee at home.

Despite this current state of affairs, no consideration is given to the relationship between current coffee mixers and coffee grinders.

Furthermore, even after use, each instrument had to be stored individually, making handling extremely complicated.

The present invention eliminates the above-mentioned drawbacks of the conventional coffee grinder and coffee brewer, and is very easy to handle.
The purpose is to provide delicious coffee using coffee powder that matches the filtration method, at a lower price than when purchased separately, and to further improve the freshness of coffee beans. The coffee powder ground by the coffee grinder attached to a part of the tank is directly received by the coffee powder storage container and paper filter installed on the bottom, and the hot water produced in the heating section is sent to the outer periphery of the coffee powder falling body. The coffee liquid is obtained by pouring it onto the coffee grounds through the dripping spout and filtering it through the paper filter, etc., and is also designed to preserve the freshness of the coffee beans for a long time to obtain delicious coffee.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a water tank having a substantially inverted shape, and is connected to a heating pipe 3 via a check valve 2 .

Reference numeral 4 denotes a heating element, which is integrally molded with the heating pipe 3 by aluminum die-casting and constitutes a heating section 6, to which a thermostat 5 for controlling electricity supply to the heating heater 4 is attached.

Reference numeral 7 denotes a base in which the heating section 6 is built-in. Reference numeral 9 denotes a coffee powder storage container to which a paper filter 8 is attached, and the coffee powder pulverized in the paper filter 8 is stored.

Reference numeral 11 denotes a bottle on which the coffee powder storage container 9 is placed, and a coffee liquid 12 is stored therein.

Reference numeral 13 denotes a coffee bean storage chamber disposed above the coffee powder storage container 9, in which coffee beans are stored.

15 is a lid of the coffee bean storage chamber 13.

A crushing section constituted by a rotary wheel 16 and exploding wheel teeth 17 is provided at the lower end opening of the coffee bean storage chamber 13.

19 is a case of a crushing section.

20 is a movable piece that opens and closes the lower end opening of the case 19; 21 is a sliding piece that guides this movable piece 20; 22 is a transmission piece; 23
is a rotating cam of the time switch 25, and 24 is an electric motor.

26 is the knob of the time switch 25, 27 is the grinding part cover, 28 is the bearing for the electric motor, 29 is the spring that pulls the movable piece in a certain direction, 30 is the coffee powder dropping body, and 31 is the dripping lug.
1-1, 32 is a worm, 33 is a worm gear, 34 is a desiccant chamber, 35 is a sealing material, 36 is a desiccant, and 37 is a pore.

Next, the process of making coffee in the above configuration will be explained.

An amount of water corresponding to the amount of coffee to be obtained is put into an inverted water tank 1 in advance, and more beans 14 than the required amount of coffee beans are put into a coffee bean storage chamber 13.

First, when the time switch knob 26 is set to the cup scale corresponding to the amount of water, the rotary cam 23 mounted coaxially with the shaft of the time switch 25 moves the movable piece 20 on the sliding piece 21 via the transmission piece 22. After that, the electric motor 24 is started.

The coffee beans 14 placed in the coffee bean storage chamber 13 are guided and guided downward, and then guided between the rotary whisk 16 in the grinding section and the external molar teeth, where the coffee beans are ground into coffee powder 1.
0, the coffee powder falls through the falling body 30 and is deposited on an air permeable filter such as a paper filter that has been pre-filled in the coffee powder storage container.

Eventually, the time switch knob 26 reverses and reaches the 0 position on the scale, and the movable piece 20 of the opening/closing section returns to its original position by the movable piece tension spring 29, thereby sealing off moisture from entering from below. To prevent.

At about the same time, the heater 4 started to be energized and for about 30 minutes
In seconds to 1 minute, the water in the heating pipe 3 is heated through the heating part 6 and becomes hot water, and the check valve 2 installed at the bottom of the inverted water tank 1 prevents it from returning to the water tank 1, so it drips. At the same time as the coffee powder is poured from the spout 31 onto the coffee grounds, a pressure drop occurs in the heating pipe 3, so that the water stored in the water tank 1 flows into the heating pipe 3 through the check valve 2.

By repeating this process, the water becomes hot water one after another and falls from the dripping port 31.

The extract of the coffee powder is then filtered through a paper filter 8 or the like having air permeability to form a coffee liquid 12 and stored in the bottle 11.

After the above operations, the coffee beans are held in the coffee bean storage chamber.

Normally, this lid has the effect of preventing dust and preventing the coffee beans from scattering outside due to the rotational force when they are ground, but according to this invention, the lid is moisture-proof, which has the greatest effect on the taste of coffee.
That is, it has the added effect of preserving the freshness of coffee beans, and its purpose is distantly related by sealing the desiccant chamber and coffee bean storage chamber integrated with the lid, and the lid.

If the desiccant chamber is inserted into the back of the lid, the desiccant can be constantly replaced with fresh material, which is even more effective.

As is clear from the above description, according to the present invention, delicious coffee can always be provided to consumers with a simple structure, and it has great practical value.
