Description

The present invention relates to the technical field of coffee bean grinding equipment, and in particular to a bean grinder container, a bean grinder, and a coffee maker.

A bean grinder quickly processes coffee beans into coffee powder, allowing you to brew coffee that suits your taste. There are several types of bean grinders currently on the market, all of which can process coffee beans into coffee powder.

However, with conventional bean grinders, coffee powder tends to remain inside the bean grinder, making it difficult to thoroughly clean the coffee powder. Because some coffee powder always remains inside the bean grinder and can remain there for a long time, each time the coffee is dispensed, some of the old coffee powder gets mixed in, resulting in an impure taste. Therefore, the problem of cleaning bean grinders is a technical problem that those skilled in the art are striving to solve.

One of the objects of the present invention is to provide a bean grinder container that solves the technical problem of bean grinders being difficult to clean.

To achieve the above objective, the technical solution adopted by the present invention is to provide a bean grinder container including a cup body and a grinding disk, the grinding disk having a hollow structure and grinding ribs on the inner wall of the grinding disk, in which a connection module is installed below the cup body, the connection module is fixed below the cup body, and the grinding disk is fixedly connected to the connection module.

The bean grinder container of the present invention has a connection module installed below the cup body. The connection module secures the grinding disc to the bottom of the cup body, allowing the grinding disc to be removed when the bean grinder container is removed from the bean grinder body. When cleaning the bean grinder container, the grinding disc can be removed by aligning it, making it easy to clean, disassemble, and assemble.

Preferably, the polishing disc is removably connected to the connection module. The polishing disc may be fixed within the connection module, or may be removably connected to the connection module. When the two are removably connected, the polishing disc can be removed from the cup body for more detailed cleaning.

More preferably, the grinding disc is removed from the cup body from below. When the grinding disc is removed from the cup body from below, there is no need to remove any extra parts, making cleaning and assembly easier.

More preferably, a removal handle is installed below the grinding disc. This removal handle allows the grinding disc to be easily removed from the cup body when removing it, and also reduces the risk of injury to the hands due to sharp edges of the grinding disc.

Preferably, the connection module includes an adjustment mechanism that controls the vertical movement of the grinding disc relative to the cup body. The adjustment mechanism controls the vertical movement of the grinding disc and can also adjust the thickness of the coffee powder. The adjustment mechanism is integrated into the cup body, so that when the bean grinder container is removed from the bean grinder main body, there are fewer parts, the bean grinder container is more reliable, and it is easier to clean.

Preferably, a seal is installed at the bottom of the cup body. This seal prevents coffee powder from scattering from the side walls of the bean grinder container, resulting in waste and contamination of the coffee powder.

Preferably, the maximum outer diameter of the lower part of the cup body is between 40 mm and 200 mm. If the maximum outer diameter of the lower part of the cup body exceeds 200 mm, the diameter of the bean grinder container will be too large, and coffee powder will be likely to scatter between the grinding disc and the cup body, making cleaning difficult. If the maximum outer diameter of the lower part of the cup body is less than 40 mm, the connecting module will be too small, making it difficult to secure to the grinding disc and resulting in insufficient grinding accuracy.

Preferably, a cup cavity is provided at the top of the cup body, and a relatively sealed grinding passage is provided at the bottom of the cup cavity, which communicates with the grinding disc. The grinding passage below the cup cavity is relatively sealed, preventing coffee powder or particles ground by the grinding disc from remaining in the grinding passage or related components.

More preferably, a bottom door is installed within the grinding passage, a control mechanism is installed within the cup body, and a switch is installed on the side wall of the cup body, which controls the opening and closing of the bottom door via the control mechanism. The bottom door may be manually or automatically controlled by the switch. The bottom door can prevent coffee beans from leaking from the bean grinder container before it is placed in the bean grinder body. The switch controls the closing and opening of the bottom door, and the control mechanism opens the bottom door before or at the same time as the bean grinder container is placed in the bean grinder body.

Another object of the present invention is to provide a bean grinder that solves the technical problem of bean grinders being difficult to clean.

To achieve the above objective, the technical solution adopted by the present invention is to provide a bean grinder that includes a bean grinder body and any of the bean grinder containers described above, with the lower part of the bean grinder container abutting against the bean grinder body and removably connected to the bean grinder body.

The bean grinder of the present invention allows the bean grinder container and grinding disc to be removed directly from above the bean grinder body, allowing the bean grinder container and grinding disc to be washed together, reducing the number of parts that need to be removed and making it easier to clean the bean grinder container and grinding disc.

Another object of the present invention is to provide a coffee maker that solves the technical problem of bean grinders being difficult to clean.

To achieve the above objective, the technical solution adopted by the present invention is to provide a coffee maker that includes any of the bean grinders described above.

When cleaning the bean grinder of the coffee maker of the present invention, the bean grinder container can be removed directly from the bean grinder body along with the grinding disc, making cleaning even easier.
