Description

Hand blender

The present invention relates to a hand blender, and more particularly, to a hand blender having a bean grinding function.

A motorized coffee grinder used for lowering coffee usually refers to a machine that crushes beans with two blades engaged by an electric motor to change the shape of the coffee bean into powder.

To use a motorized coffee grinder, pour coffee beans into a hopper that holds coffee beans at the top, and when the power is turned on, grinders are rotated while one blade is fixed, and ground coffee that is gravity- And the pulverized powder is discharged through the discharge port. At this time, coffee powder is put into the container.

However, the conventional grinder is not only cleaned by water, but also has a strong static electricity when the coffee is crushed, and the bean sprouts are attached to the periphery of the grinder blade, the discharge hole and the powder container. As a result, there is a loss of the attached beans, and the attached coffee powder is easily sour because it has a lot of fat, so it is not easy to remove the attached powder even though it is difficult to separate even around the grinder blade, .

In addition, a stationary coffee grinder is a structure in which a large bean grinder is shaken out in order to change the type of bean, but in reality, it is not possible to shake a grinder over 20 kilograms. In the end, there are losses such as those that use a variety of beans, such as a method of removing a new bean from a grinder blade while naturally adding a new bean to a new bean so that the taste of the new bean does not mix with the original bean. In the end, high-quality coffee using various beans [【【?] Is equipped with a plurality of bean grinders so as not to cross the bean flavor.

On the other hand, as the number of users of coffee beans has increased in recent years, there is an increasing need to use beans with a grinder for crushing beans and a dripper for pouring water into pulverized bean flour in general households.

However, in the case of a motorized bean grinder, since it is expensive, it is expensive to purchase it from general furniture.

In order to solve this problem, it may be considered to crush the beans by using a household blender such as a hand blender, but a household blender equipped with a rotary knife for juicing or stirring food has a bean- It is not suitable to replace a conventional grinder for forming a powder.
