Description

[Detailed explanation of the idea] The present invention relates to a coffee maker with a grinder.

Various types of coffee makers with a grinder are commercially available, in which a coffee mill is integrated with a coffee maker.

These devices do not offer sufficient safety and convenience.

For example, pouring hot water directly into the mill when brewing coffee may damage the mill and take time to clean it, or the mill and coffee maker may be separated, such as transferring ground coffee powder to another container and extracting coffee. However, there are many cases where similar operations must be performed.

Furthermore, at present, sufficient safety measures have not been taken to prevent careless use of the rotary blade of the mill.

Therefore, an object of the present invention is to provide a coffee maker with a grinder that takes safety into consideration by allowing the coffee mill to operate only when the coffee grinding degree adjusting filter and/or the coffee strainer of the coffee maker are installed in a predetermined position. It is in.

Another object of the present invention is to provide a coffee maker with a grinder that is easy to use by using the strainer of the coffee maker as a coffee powder receiver.

Still another object of the present invention is to provide a coffee maker with a grinder in which the coffee strainer holder has a hole covered with a removable bottom cover, thereby making cleaning and maintenance, which are problems with this type of product, easier. There is a particular thing.

A preferred embodiment of a coffee maker with a grinder according to the present invention that achieves the above and other objects will be described in detail with reference to the drawings.

The coffee maker with a grinder according to the present invention has a housing 1 divided by a partition wall 2 into a coffee maker part and a coffee mill part.

Some parts of the coffee maker do not constitute the essential parts of the coffee maker with a mill of the present invention, so they will be briefly explained.

When the lid 3 of the coffee maker is partially removed, the cold water enters the heater 6 from the cold water tank 4 as shown by the arrow 5.
The hot water heated here rises in the pipe 8 as shown by the arrow 7 and is poured from the pouring port 9 as shown by the arrow 10.

A cup 11 for receiving coffee extract is placed on the heater 6, a coffee strainer 12 is placed on the cup, and a hot water diffuser 13 is placed on the coffee strainer 12.

The hot water poured from the pouring port 9 is directed by the arrow 14 on the diffuser 13.
Coffee powder -H in the coffee strainer 12 as shown in
The coffee extract is evenly distributed over the water, and the coffee extract falls into a cup after passing through a filter 15 (see FIG. 5).

On the other hand, the motor part 16 of the coffee mill is housed in a sub-housing 17 between the housing 1 and the partition wall 2, and a rotary blade 19 for crushing coffee beans is attached to the lower end of a motor rotary wheel 18 protruding from the sub-housing 17.

A coffee bean hopper 20 is defined between the housing 1 and the sub-housing 17, and coffee beans are poured into the coffee mill after removing the lid 21 of the coffee mill.

The hopper 20 communicates with a coffee grinding chamber 22 in which a rotary blade 19 is located, the bottom of which is defined by a coffee powder coarseness adjusting filter 24 that is removable on a filter receiver 23 (see FIG. 3).

Below the coffee grinding chamber 22 is a strainer holder 25 on which the coffee strainer 12 of the coffee maker can be attached.
will be established.

A hole 26 is formed in this pedestal in order to facilitate cleaning and maintenance of the mill part in particular, and it can be fixedly attached to the pedestal 25 with a hooking protrusion 27, as shown in a partial view in FIG. It is preferable to configure it so that it can be covered with a volume cover 28.

Further, as shown in FIGS. 1 and 4, a cord clamp 29 may be formed at the bottom of the pedestal 25 so that an electric cord (not shown) of the coffee maker can be stored when not in use.

In the coffee maker with a mill according to the present invention, the mill motor 16 is configured so as not to operate unless the roughness adjustment filter 24 is installed in a predetermined position, especially in consideration of safety.

This filter was slidably inserted onto the filter receiver 23 as shown in FIGS. 1 and 3, and the protrusion 31 formed on the handle portion 30 of the filter 24 engaged with the end of the housing 1 and was positioned at a predetermined position. At this time, the opposite end of the filter 24 is configured to close the normally open switch 32, ie, turn on the mill motor circuit.

As a result, as shown in FIG. 6, the mill motor 16 is activated by turning on the main switch 33, and the rotary blade 19 is rotated to crush the coffee beans.

The filter 24 is for adjusting the roughness, and is preferably replaceable with several types having different coarse meshes so that the user can select one according to his/her preference.

Furthermore, the present invention is configured so that the coffee strainer 12 placed on the top of the cup 11 can be mounted on a pedestal 25 as shown in FIGS. 1 and 2.

This allows you to transfer the ground coffee powder to another container and extract coffee, unlike a conventional coffee maker.
This inconvenience in use can be eliminated.

Further, it is preferable for safety to turn on the milling circuit when the coffee strainer 12 is mounted, just as the milling circuit is turned on when the roughness adjustment filter 24 described above is mounted.

In this case, although not shown, a switch similar to switch 32 is configured to be activated when the coffee strainer is installed in a predetermined position.

This switch is inserted in series with switch 32 in the circuit of FIG.

This provides double safety for the extremely dangerous coffee grinder.

To use, first set the filter 24 of the desired roughness and the coffee strainer 12 in the predetermined positions, put the coffee beans into the hopper 20, turn on the main switch 38, and then the rotary blades 19 will be rotated by the rotation of the motor 16. The coffee beans are ground and coffee powder corresponding to the coarseness of the filter is deposited on the coffee strainer 12.

If you place this on the cup 11 as it is, you can prepare for brewing coffee with just this, and it is very simple and does not require any complicated work.

However, during or after coffee extraction, some of the water vapor may flow back toward the water tank 4 from the sprue 9 and moisten it through the lid 21 of the coffee bean inlet of the mill section.

Therefore, as shown in FIG. 1, the partition wall 2 needs to be sufficiently high and configured to prevent water vapor from flowing into the mill section as much as possible.

There has never been a coffee maker with a grinder that is safe, easy and convenient to use, and takes into consideration cleaning and maintenance, and the present invention is new.
