Description

A mixer capable of power transmission using magnetic force {A Mixer Possible Power Transmission Using Magnetism}

The present invention relates to a mixer equipped with a power transmission means capable of receiving a driving force from the motor to rotate the grinding screw, and more particularly, in the power transmission means for connecting the drive side and the driven side, The present invention relates to a mixer capable of transmitting power by using a magnetic force, which is capable of forcing rotation of a driven screw on a driven side by magnetic restraint.

Usually, the driving means mounted on the mixer is almost all of the electric motor driven by the applied electric.

The electric motor rotates the grinding screw to crush fruits or vegetables. Generally, the electric motor is driven in a state where the driving plate on the electric motor side and the driven plate on the grinding screw side are engaged with each other. It is provided with a power transmission means for driving by applying.

In this way, the drive plate is coupled to the drive shaft of the electric motor, and the driven plate is coupled to the driven shaft of the grinding screw in the drive plate and the driven plate of the existing mixer to transfer the power corresponding to each other in shape have.

There is also.

In addition, the driving plate and the driven plate is usually made of a rubber material there is a problem that the reverse odor occurs due to the surface deterioration by frictional heat when combined with each other at high speed rotation.

In addition, when the amount of food to be ground or a relatively solid material is mixed, the rotation of the grinding screw may be stopped, at this time, because the driving of the electric motor is also stopped or decelerated, continuous electricity at this time There is a problem in that the internal coil of the electric motor is deteriorated due to the application and eventually lead to failure of the motor.
