Claims7
A washing machine, comprising:
- a washing tub that holds laundry;
- a moving magnet connected to or with the washing tub that horizontally reciprocates and/or oscillates together with the washing tub;
- a horizontal guide that supports the moving magnet and guides the moving magnet;
- an electromagnet having a magnetic field configured to horizontally move the moving magnet by magnetic force;
- a controller configured to control a current supplied to the electromagnet, causing the magnetic field of the electromagnet to switch direction, which causes the moving magnet to horizontally reciprocate and/or oscillate;
- and
- at least one damper between the washing tub and the moving magnet configured to dampen vertical movement and/or vibration of the washing tub and support the washing tub and/or the moving magnet,
- wherein the moving magnet has a contact member that contacts a lower surface of the washing tub and configured to support a pivot point to the washing tub, and both sides of the contact member are inclined in a direction away from the lower surface of the washing tub.
