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.

Claims (35)

1 . 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.

2 . The hinge according to claim 1 , wherein said snap fitting device comprises a plurality of tabs emerging from said box-shaped element and a corresponding plurality of cavities formed in said containment cartridge and shaped to match said tabs.

3 . The hinge according to claim 1 , and further comprising 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.

4 . The hinge according to claim 1 , wherein said first elastic element is a compression element, wherein said containment cartridge defines, with a relative distal end face, an abutment for said first elastic element.

5 . The hinge according to claim 1 , and further comprising an actuator for actuating said damping member, wherein said actuator comprisest prise a slide slidably engaged on said box-shaped element, said slide having a tooth configured to exert a thrust against said damping member.

6 . The hinge according to claim 5 , wherein said containment cartridge has a slot configured to allow feeding of said tooth during actuation of said damping member.

7 . The hinge according to claim 5 , wherein said actuator comprises a cam-shaped lever supported by said containment cartridge and acting on the damping member.

8 . The hinge according to claim 5 , wherein said cam-shaped lever is interposed between said tooth and said damping member.

9 . The hinge according to claim 5 , wherein said actuator comprises a thrust element positioned on said first lever and configured to engage by pushing against said slide.

10 . The hinge according to claim 2 , and further comprising 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.

11 . The hinge according to claim 10 , wherein said first elastic element is a compression element, wherein said containment cartridge defines, with a relative distal end face, an abutment for said first elastic element.

12 . The hinge according to claim 3 , wherein said first elastic element is a compression element, wherein said containment cartridge defines, with a relative distal end face, an abutment for said first elastic element.

13 . 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 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.

14 . 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 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

wherein said first elastic element is a compression element, wherein said containment cartridge defines, with a relative distal end face, an abutment for said first elastic element.
