Abstract
Described is a hinge for doors of electrical household appliances, including a first lever and a box-shaped element pivoted to each other and movable relative to each other in a tiltable fashion, fixable one to a frame and the other to a door of an electrical household appliance, to make the door movable relative to the frame between a closed position and an open position, a first elastic element connected to the first lever and designed to generate, with a relative deformation, an elastic reaction force designed to compensate at least partially the weight force of the door during the opening or closing of the door, a damping member housed inside a containment cartridge.
Claims14
A hinge for doors of electrical household appliances, comprising:
- a box-shaped element having a main direction of extension,
- a pivot pin
- a first lever pivoted on said box-shaped element by the pivot pin one of either the box-shaped element or the first lever being fixable to a frame of an electrical household appliance and the other of either the box-shaped element or the first lever being fixable to a door to make the door tiltably movable relative to the frame between a closed position and an open position,
- a first elastic element positioned outside said box-shaped element, operatively connected to said first lever and configured to generate with a relative deformation an elastic reaction force for compensating at least partially a weight force of the door during the opening or closing of the door,
- a damping member for applying a damping action during the-reciprocal motion of said first lever and said box-shaped element, at least in a proximity of the closed position,
- a containment cartridge for containing said damping member, wherein said containment cartridge is positioned externally projecting from said box-shaped element and interposed between said box-shaped element and said first elastic element;
- and
- a snap fitting device configured to stably engage said containment cartridge with an end portion of said box-shaped element.

- a pivot pin,
- a first lever pivoted on said box-shaped element by the pivot pin, one of either the box-shaped element or the first lever being fixable to a frame of an electrical household appliance and the other of either the box-shaped element or the first lever being fixable to a door to make the door tiltably movable relative to the frame between a closed position and an open position,
- a first elastic element positioned outside said box-shaped element, operatively connected to said first lever and configured to generate with a relative deformation an elastic reaction force for compensating at least partially a weight force of the door during the opening or closing of the door,
- a damping member for applying a damping action during reciprocal motion of said first lever and said box-shaped element, at least in a proximity of the closed position,
- a containment cartridge for containing said damping member, wherein said containment cartridge is positioned externally projecting from said box-shaped element and interposed between said box-shaped element and said first elastic element;
- and
- a control rod for controlling said first elastic element, said control rod moving parallel to said main direction of extension of said box-shaped element, wherein said containment cartridge comprises a through slot, said control rod engaging slidably inside said through slot.
