Description

Remaining amount of ground coffee and caking removal device for coffee grinder

The present invention relates to a coffee grinder, and more particularly, to a residual amount of ground coffee for a coffee grinder and a device for resolving clumps, which can prevent the remaining amount of ground coffee beans from remaining or clumping due to static electricity at a discharge port.

Recently, as the demand for coffee has increased, coffee beans that can feel the unique flavor and taste of coffee are widely consumed instead of instant coffee.

In general, coffee beans are prepared by pouring hot water into the ground coffee bean powder and dripping water as it passes through the coffee bean powder and extracting the coffee bean liquid.

As interest in and demand for coffee beans increases, the number of coffee beans being brewed by direct grinding with a coffee bean grinder at home, office, or outdoors is increasing significantly.

In addition, the demand for coffee bean vending machines that manufacture coffee beans by directly grinding coffee beans with a built-in automatic coffee bean grinder is also increasing.

A conventional coffee bean grinder includes a grinder housing into which beans are put, and a grinding blade rotatably positioned in the grinder housing, and grinds the beans introduced into the grinder housing by rotation of the grinding blade between the grinder housing and the grinding blade.

Coffee grinders for cutting or grinding coffee beans are ground in various ways according to the shape of the blade, and among them, a conical burr and a flat burr are representative.

The blades placed on the bottom of both sides rotate to grind the coffee. Among them, the conical burr rotates at about 500 revolutions per minute, and the flat bur at about 1500 revolutions per minute.

In addition, when looking at the moving direction of the ground coffee beans, the conical burr is discharged from top to bottom, and the flat burr is discharged sideways by centrifugal force.

On the other hand, in the conventional coffee grinder, in the process of grinding and discharging coffee beans, a residual amount is left in the discharge port due to static electricity or the ground coffee is agglomerated, which is inconvenient and wasteful of the ground coffee is severe, so improvement measures are required.

The above-described technical configuration is a background for helping understanding of the present invention, and does not mean a conventional technique widely known in the technical field to which the present invention pertains.

Accordingly, it is an object of the present invention to provide a residual amount of ground coffee for a coffee grinder and a device for resolving clumping, which can prevent the remaining amount of ground coffee beans from remaining or clumping due to static electricity at a discharge port.

According to an aspect of the present invention, the main body coupled to the housing of the coffee grinder; a discharge post coupled to the main body and provided as a discharge passage for ground coffee beans; a rotation handle rotatably coupled to the discharge post and provided as a handle; And one side is coupled to the rotary handle and the other side is provided to protrude from the upper end of the discharge post, and rotates like the rotary handle to scrape the inner wall of the discharge post. can be provided.

The wiper unit may include a coupling ring coupled to a lower portion of the rotation handle; a first straight portion provided parallel to the coupling ring; and a second straight part provided to be inclined upwardly from the first straight part and having an upper end disposed adjacent to an outer wall of the discharge post.

The wiper part includes a third straight part having one end extended from the second straight part and the other end exposed to the upper end of the discharge post, and the third straight part is disposed close to the inner wall of the discharge post, and the It may be provided parallel to the inner wall of the discharge post.

a zigzag portion provided at an end of the third straight portion and provided in a zigzag shape; And it may further include a ring portion provided to be bent in the downward direction from the end of the zigzag portion.

The rotation handle may include a handle body coupled to an outer wall of the discharge post and through which the discharge post passes; a bearing member having one side inserted into the handle body to surround the discharge post; and a coupling body that is detachably coupled to the handle body, the other side of the bearing member is inserted, and supports the stepped portion of the discharge post.

It may further include a plunger unit coupled to the main body to remove the coffee bean powder adhered to the wiper unit by hitting the wiper unit.

The plunger portion may include: a plunger body coupled to a body hole provided in the body; and a striking protrusion provided at an end of the plunger body to penetrate the inner wall of the discharge post and striking a third straight portion of the wiper unit.

In the embodiments of the present invention, the coffee beans ground by the wiper unit that is rotatably coupled to the discharge post and rotates like a rotation handle and a rotation handle provided as a handle to scratch the inner wall of the discharge post are rotatably coupled to the discharge post, and the remaining amount is due to static electricity at the discharge port. It can be prevented from remaining or clumping.

In addition, it is possible to more effectively prevent the agglomeration of the ground coffee beans by dispersing the ground coffee beans that are ground by the wiper part rotated like the rotary handle and fall to the discharge post.
