Definitions

  • the present invention refers to an electric household appliance provided with a door for closing an internal chamber, particularly to a top loading washing and/or drying laundry machine.
  • the present top loading washing and/or drying laundry machines are provided with a drum adapted to store the laundry to wash and/or dry which is located at a central position of the laundry washing machine and it has an opening on the top part of the machine.
  • This drum is arranged in revolving way inside a container, called washing tub, which is assigned to contain the washing liquid and which is equipped for fixing the suspension units allowing to be suspended inside a cabinet storing the laundry washing/drying machine.
  • the top opening of the drum is generally closed by a metal door provided generally with two wings, which are normally shut with each other by means of coupling means; in such way the door is kept closed during the meaning of the machine.
  • the opening of the drum is aligned with the opening of the cabinet on the top of the same for loading the laundry to wash or to dry.
  • the opening of the cabinet is closed by means of a door hinged with the cabinet at one its end and at the opposite end it is provided with a closing device engaged with the cabinet.
  • control instrumentation of the machine is arranged on the front of the door, preferably in a frontal sloped portion of the same at the end of the door where the closing device is provided. This makes heavy the structure of the door.
  • the door is provided with two hinges provided with springs or other elastic elements for making easy the opening thereof; the closing of the door occurs by means of a pushing downstream of the user.
  • said elastic elements cannot any more support the weight of the door; this causes a spring lock of the door and such operation can result insecure for the user in the case of accidental crash with handles or arms.
  • an electric household appliance comprising a frame with a top panel provided with an opening for acceding into an internal chamber of the electric household appliance and with a door adapted to close said opening, said door being coupled with said panel by means of at least one hinge, said hinge comprising first means integral with the edge of said opening and second means coupled with said door at a first end and with said first means at a second end so as to rotate around a horizontal axis, said hinge comprising elastic means coupled with said first means and with said second means to urge the rotation of said second means towards the opening direction of said door to a position of total opening of the door, said door being kept closed by means of a bolt releasable by an unhooked button, characterized in that said electric household appliance comprises third means adapted to brake the rotation of said door towards the closing direction of the same door when the door is open.
  • said third means determine a stopping position of the door which is intermediate between the closing position and the total opening position when the combination of the braking action thereof and the action of urging the rotation of said elastic means balances the weight force in the door.
  • FIG. 1 the top of a top loading laundry washing machine is shown; said machine comprises a frame 1 provided with a top panel 2 where an opening 3 is formed for entering into the washing tub 9.
  • the opening 3 is closed by means of a door 4 hinged to the panel 2 so as rotate around a horizontal axis P in order to allow the access inside of the washing tub 9.
  • the door 4 is hinged to the panel 2 at a first end 5 while at a second end 6, opposite to the end 5, a bolt 7 is provided for closing the door 4; said bolt 7 is coupled with an unhooking button 8 to open the door 4.
  • the door 4 comprises control instrumentation 100 of the laundry washing machine which make heavy the structure of the door. Said instrumentation 100 is preferably arranged next the end 6 and in a sloped part of the door 4. It is even possible that a display adapted to visualize the commands and/or the different operative steps of the laundry washing machine is arranged together with the control instrumentation.
  • a hinge 20 is located which comprises a flask 21 integral with the panel 2 and a cavity 22 having a curvilinear vertical section and a rectangular transversal section; said cavity 22 comprises an top rectangular edge 23, more visible in Figure 2.
  • An arm 25 is hinged with the flask 21 that is constituted by a curved portion 26 and by a substantially rectilinear portion 27.
  • the curved portion 26 is hinged with the edge 23 of the flask 21 by means of a horizontal pivot 28 extending along the axis P; the curved portion 26 can rotate around the P axis partially inside the cavity 22.
  • the portion 27 of the arm 25 is connected by means of screws 30 with the door 4.
  • the panel 2 comprises two hinges 20 for fastening the door 2 to the cabinet 1.
  • Elastic means 40 constituted by two helicoidal springs 41 are coupled with the flask 21 and with the arm 25.
  • the central part 42 of a spring 41 is arranged around the pivot 28, an end 43 goes in abutment against the edge 23 of the flask 21 and the other end 44 goes in abutment against the curved part 26 of the arm 25.
  • the springs 41 urge the arm 25 to rotate in anticlockwise way around the pivot 28 that is towards the opening direction of the door 4.
  • a means 50 adapted to stop the rotation of the door 4 in the closing direction of the door 4 is arranged.
  • Said means 50 generally constituted by a rubber plug or other material having similar elastic properties, is arranged in adjacent way with the curved portion 26 of the arm 25, preferably outside the cavity 22 of the flask 21. Since the action of the elastic means 40 is an action of urging to the anticlockwise rotation of the door 4 towards the opening direction, the combination of said action of the elastic means 40 and the action of the rubber plug 50 opposes the action of the weight force of the door 4 which tends to close the door 4 by means of a rotation around the axis P towards the closing direction.
  • the action of said plug 50 is to brake, for friction between the curved portion and the same rubber plug 50, the rotation of the door 4.
  • a stop of the door 4 is obtained before the closing thereof when the combination of the aforementioned action of the elastic means 40 and of the stopping action of the plug 50 is equal to the action of the weight force in the door 4.
  • the curved portion 26 has a cam function so that the positive gradient puts a greater pressure on the plug 50 next the closing of the door 4, that is the combination of the higher or lower value of the profile of the curved portion 26 and the compression capacity (hardness) of the plug 50 allows a gradual and adsorbed braking of the door, which is calibrated on the same door with suitable values of pressure on the closing.
  • FIG. 1 A detail of the laundry washing machine with closed door in Figure 1 is shown in magnified view; particularly the hinge 20 and the rubber plug 50 arranged in adjacent way to the curved portion 26 of the arm 25 are shown.
  • the rubber plug 50 has a curved portion 51 that faces to the curved portion 26.
  • the stopping position A of the door is more specifically next the closing position of the same. It is possible to have a stop or a greater braking of the door 4 in more positions wherein the same door 4 has a slope of a variable angle D with respect to the closing position of the door 4. This is caused by the gradual and adsorbed braking due to the friction of the curved part 26 having a cam function with the rubber plug 50; in fact the profile of said curved portion 26 has such a shape so that the combination of it and the rubber plug provides a gradual and adsorbed braking of said door 4 towards the closing direction of the same.
