Definitions

  • the present invention relates to a device for hinging a door, in particular a dishwasher door, to a fixed structure.
  • Doors of the aforesaid type are subjected to the action of an elastic element set in such a way as to constantly return the door towards the position where it shuts off the compartment.
  • the elastic elements and, more in general, the hinging devices comprising them require particular structures to determine returning actions varying with laws correlated to the laws governing the variation of the actions induced by the weight force.
  • the doors' own weight is far greater than that of similar doors fitted to other appliances such as kitchen ovens.
  • the panel also supports the dishwasher's command, control and adjustment circuitry and, most importantly, it supports the panels which integrate the dishwasher aesthetically with the furniture it is embedded in.
  • the weight which is much greater than that of appliances with similar opening actions, implies structuring and dimensioning the hinging devices in a way that is wholly specific to the dishwasher sector.
  • the purpose of the present invention therefore is to eliminate the aforementioned drawbacks by means of a hinging device of the kind indicated in the preamble to claim 1, and such as to be usable indifferently on the doors of all types of dishwashers and regardless of the weight of the equipment contained within the door and/or of the weight of the panels supported externally.
  • this purpose is reached by means of a device comprising a leverage which is operationally placed between the door and the elastic element, and is provided with a kinematic chain having reciprocally articulated rods arranged in succession.
  • the first and the last rods of the kinematic chain are connected respectively to the door and to the elastic element and are mounted on the fixed structure in such a way as to rotate around fixed axes.
  • the first rod of the kinematic chain is fitted with joints located at a reciprocal distance which is smaller than the distance between corresponding end joints of the last rod, such last rod hinging with the elastic element on a pivot which is located at a distance from the fixed rotating point of the last rod not exceeding the distance between the first rod's joints.
  • 1 is the label indicating in its entirety a device for hinging to a fixed structure 2 a door 3, in particular of an embedded dishwasher.
  • Fixed structure 2 is represented in the Figures by a metal plate which is made integral with the casing of the dishwasher.
  • Door 3 is mounted on a vertical wall, not represented, of the casing, it can swivel around a fixed horizontal axis 5, borne by the structure 2 in correspondence with the lower horizontal side of the door 3, and it is interconnected with an elastic element 6 structured in such a way as to contrast the opening motion of the door 3 from the vertical position in Figure 1 to the horizontal position in Figure 2.
  • the elastic element 6 preferably comprises a helical compression spring, mounted on the fixed structure 2 in such a way as to yield along an essentially vertical line 14.
  • a leverage 7 is operationally placed, whose purpose is to correlate proportionately, and as a function of the opening angle (alpha) of the door 3, the intensity of the return action of the spring with the moment of rotation of the door 3 generated by the latter's own weight.
  • the leverage 7 comprises more in particular a kinematic chain 7a with reciprocally articulated rods 10, 9, 8, arranged in succession.
  • Rods 10, 8 at the ends of the kinematic chain 7a are interconnected with the fixed structure 2 by means of hinges which allow the angular oscillation of rods 10, 8 around fixed axes 5, 11.
  • the first rod 10 is integral with the door 3 in whose structure it is directly integrated.
  • the last rod 8 instead is connected to a rod 21 guiding and compressing the spring 6, by means of a connecting rod 20 interposed and fitted with ends articulated on pivots 13a and 13b.
  • Figures 1 and 2 show in particular that the kinematic chain 7a preferably presents a proportioning in the length of the respective rods 10, 9, 8 and a distance between the fixed axes 5, 11 suited to define an articulated quadrilateral.
  • the end rods 10, 8 function as rocking levers connected to each other by an intermediate connecting rod 9 and oscillating on the fixed structure 2. Furthermore, observing in particular Figure 1, it can be seen that the first rod 10 of the kinematic chain 7a presents articulated joints 10a, 10b for connection with intermediate connecting the rod 9 and with the fixed structure 2, which joints are located at a reciprocal distance smaller than the distance between the corresponding articulated joints 8a, 8b connecting the last rod 8 to the intermediate connecting rod 9 and to the fixed structure 2.
  • pivot 13a itself is located at a distance from the fixed axis 11 of the last rod 8 which does not exceed the distance between the articulated joints 10a and 10b of the first rod 10.
  • the pivot 13a furthermore is preferably displaced laterally with respect to the straight line 15 ideally connecting the end joints 8a and 8b of the last rod 8. This lateral displacement is performed preferably by the same part of the door 3 in such a way as to cause, during the use of the device 1, the door 3 to close without striking the structure 2 of the dishwasher casing.
  • the articulated quadrilateral presents, when the door 3 is in the closed condition, an angle B measuring about 80° between the first rod 10 and a straight line 50 passing through the fixed axes 5 and 11; an angle G measuring about 80° between the last rod 8 and the straight line 50; an angle D measuring about 80° between the last rod 8 and the intermediate rod 9; an angle T measuring about 120° between the intermediate connecting rod 9 and the first rod 10; an angle F measuring about 70° between the line 50 passing through the fixed axes 5 and 11 and the straight line 51 passing through the articulation axis 11 of the last rod 8 and the pivot 13a articulating the elastic element 6.
  • the articulated quadrilateral assumes for said angles, when the door 3 is in the open configuration, values measuring about 170° for angle B, 10° for angle G, 160° for angle D, 20° for angle T and 0° for angle F.
  • An alternative embodiment of device 1, illustrated in Figures 4 and 5, also entails the provision of means 16, 17 for adjusting the displacement of the pivot 13 with respect to the straight line 15 passing through the joints 8a, 8b.
  • These means comprise a slot 16 which is developed along a circumference arc which is obtained on the last rod 8 and which houses the pivot 13a that connects, with the last rod 8, the connecting rod 20 of the elastic element 6.
  • An adjusting screw 17 is operationally placed between the slot 16 and the pivot 13a to vary the position of the pivot 13a with respect to the slot 16 and thus with respect to the aforesaid straight line 15.
  • Hinging device 1 designed according to the invention in use, reveals a global elastic reaction which is quite insensitive to external load variations even when induced by strong variations in the weight of the door 3.
  • the device is suited to be applied practically to all known models of embedded dishwashers, whatever the type of lining panel adopted.
  • the device 1 can also be manufactured in a single body thus allowing for quick and easy mounting on the casing of the appliance it is destined for.
