Samsung patents washing machine motor with sliding clutch for different modes
Samsung has secured a patent for a motor design used in laundry appliances that features a specific type of clutch. This clutch uses a sliding part that connects to the spinning rotor via small protrusions when the machine switches between different operating modes.
In the filing’s own words
A driving device including a stator; a rotor including a rotor frame and provided to be rotatable about a rotational axis of a clothing treatment device through interaction with the stator; and a clutch including a movable member configured to slide along the rotational axis to be selectively coupled to the rotor according to an operation mode of the clothing treatment device. The rotor frame may include a plurality of holes, and a plurality of coupling protrusions protruding toward the clutch so as to be coupled with the movable member when the movable member is slid to be coupled to the rotor. The plurality of coupling protrusions are integrally formed with the rotor frame and punched out of the rotor frame to form the plurality of holes.
What exactly they claim (claim 1)
1. A driving device, comprising: a stator; a rotor including a rotor frame and provided to be rotatable about a rotational axis of a clothing treatment device through interaction with the stator; and a clutch including: a movable member, including a locking recess, configured to slide along the rotational axis to be selectively coupled to the rotor according to an operation mode of the clothing treatment device, wherein the rotor frame includes: a plurality of holes, and a plurality of coupling protrusions protruding toward the clutch so as to be coupled with the locking recess of the movable member along a radial direction of the rotor frame based on the movable member being slid to be coupled to the rotor, and wherein the plurality of coupling protrusions are integrally formed with the rotor frame and punched out of the rotor frame to form the plurality of holes, and the plurality of coupling protrusions are inserted into the locking recess.
