Description

Rotary Mixer {ROTARY MIXER}

The present invention relates to a rotary mixer, and more particularly, to a rotary type mixer in which a vessel body and a cap member are automatically rotated about a rotary shaft during a mixer process of a pulverized product so as to agitate the pulverized material using a centrifugal force generated during rotation, And more particularly to a rotary mixer whose structure is improved to improve efficiency.

Generally, in a blender, an electric motor is rotated by a power supply, and blades or blades are rotated by an electric motor to mix and / or crush food.

However, since the conventional blender is rotated while the position of the crushing blade is fixed, the food is disposed at the outer periphery of the crushing blade by the centrifugal force of the crushing blade after the crushing for a predetermined period of time.

Therefore, in order to crush the less crushed food, there is a problem that the user takes the blender and shakes or impacts the crushed food to move the food placed in the crates to the crushed blade position.

The user is inconvenient to use because it shakes or shakes the whole blender, and there is a risk of damage due to strong impact on the blender.

In addition, when the content of food or the like is not well pulverized, the motor is sometimes rotated at an extremely high speed, thereby shortening the service life of the motor and increasing the electric charge.

As a prior art for improving this, as disclosed in Korean Patent Registration No. 10-1681896 entitled " Shaking Mixer " (Registered on Nov. 31, 2016), a mixer for crushing or mixing foods contained therein by a rotating blade A main body having a built-in motor; A receiving portion coupled to the main body and receiving food therein; A blade mounted on the main body or the receiving portion and rotated by the motor to crush or mix food; A base disposed at a lower portion of the main body; And a driving part disposed between the base part and the main body and supporting the main body in the up-and-down direction with respect to the base part, wherein the driving part moves the main body in the up-down direction or the left- And the food contained in the receiving portion is mixed as the main body moves in the up-down direction or the left-right direction by the driving portion.

The driving unit adopts a coil spring. In this case, the user moves the main body and the receiving unit by swinging in a state holding the main body or the receiving unit, or applying the external blow to the left and right directions, To be pulverized.

In this case, there is a disadvantage in that the user must shake the main body and the receiving part or externally strike it while observing the mixing process of the blender, and there is a fear that the pulverized material in the receiving part may not be mixed well with the unidirectional simple shaking flow of the coil spring .

Other prior art related to conventional mixers include a base member, as disclosed in Korean Patent Registration No. 10-1760710 entitled " Up and down and swing type mixer " (registered on July 17, 2017); A hollow rotating member having a lower portion rotatably hinged to an upper portion of the base member; A main body disposed movably in a vertical direction within the rotary member; A receiving member detachably coupled to an upper portion of the main body, the receiving member having food therein received therein and having a blade disposed therein; A vertical elastic member elastically supporting the main body movably in a vertical direction within the rotary member; And a horizontal elastic member having one end coupled to the base member and the other end coupled to the rotary member to elastically support the rotary member in the left and right directions, wherein the body moves up and down independently of the rotary member And the horizontal elastic member restores the rotary member and the main body to the original position when the rotary member and the main body are inclined by the external force in the left and right direction.

However, the conventional mixer can easily grind food by moving in the upward and downward directions so as to facilitate grinding of the pulverized material in the left and right directions. In this case, however, There is a fear that the effect of agitation and crushing of the pulverized material may not be sufficient because of the simple shaking motion.

Korean Registered Patent No. 10-1681896 " Shaking Mixer " (Registered on Nov. 31, 2016) Korean Patent Registration No. 10-1760710 entitled " Up-Down Moving and Swing Type Mixer " (registered on July 17, 2017)
