Definitions

  • the present invention is related to a spring device connected to the hinge of a fold-down door on a household dishwasher appliance, for balancing the opening of the door.
  • the door hinge On a dishwasher appliance with a front fold-down door, the door hinge has a horizontal swivel pin at the bottom of the door and its opening is balanced by means of a device provided with a mechanism of two coil springs anchored to the casing walls.
  • the weight of the door varies from one appliance to another depending on whether it has a cover panel or not and the device for balancing the opening of the door is the same on all appliances of all types, a compensation spring being connected at each of the two side walls from the casing of the appliance to the door hinge, each by means of a respective transmission cord, with the assistance of a means for the initial adjustment of each of the two springs, or prior spring tensioning.
  • the balancing device has to compensate the moment of the weight of the door and of its cover panel in order to keep the door open at any angular opening position.
  • the dishwasher appliance described in US-A-5980006 contains the combination of the components described in the preamble of claim 1.
  • the balancing device belonging to the prior art comprises various parts that are complicated to mount for the transmission and adjustment of the pre-tension of the springs mechanism, which is fitted occupying a space on the both side walls of the appliance.
  • the installation of the prior art balancing device including two compensation springs supported by the casing requires the prior fitting of the door and subsequently the fitting of a spring on either opposite side of the casing.
  • This succession of fitting operations is a drawback for manufacture and generates an additional economic cost, since for the installation of both springs, the appliance casing has to be turned over and re-oriented in relation to the position of the working person. Further, for the replacement of the spring when it breaks due to continual use it is necessary to remove the side wall panel from the appliance in order to gain access to the spring housing.
  • the invention is a device for balancing the opening of a fold-down door of a household dishwasher appliance, attenuating the door opening movement by means of a single door weight compensating spring, an horizontal swivel pin, and a hinge, as defined in claim 1.
  • the balancing device uses flat-shaped moulded parts, thereby facilitating the assembling of the device and its fitting on the casing of the appliance, and it uses a single compensation spring, which extends inside the casing parallel to the door swivel pin.
  • the single spring installed in this way is held without support, by being pulled from either end in opposite directions by two transmission cords.
  • the balancing device offers an advantage for the assembly of the dishwasher appliance, since, as it consists of a single spring in an internal front location, its installation is done entirely in the same stage as the rest of the internal components from the upper opening in the casing, without movable or turning the appliance over, while the door is fitted at the final stage of assembly. For the subsequent replacement of the spring access is gained easily to the spring housing from the front of the appliance.
  • a balancing device 1 is connected to a door 2 of a dishwasher appliance provided with a dishwasher casing 3, the door being fold-down at the front by means of a door hinge 4 fitted with a swivel pin 5.
  • the balancing device 1 comprises a single compensation spring 5 for attenuating the door opening movement "A", the moment Mg of the door 2 being compensated by means of the moment Ms of the force Fs of spring 5, in respect of pin 5 too.
  • the balancing device 1 comprises a single helical compensation spring 6 and two identical tensioning assemblages 7-11 made of moulded plastic, secured respectively in a symmetrical manner on two opposite side walls of the casing 3.
  • Each of these symmetrical tensioning assemblages 7-11 comprises a cord 7 with an end 7a connected to one of the two side hinges 4 for transmitting a force Fs of spring 6 to door 2 in a given direction 14 (FIG.
  • the tensioning assemblage 7-11 comprises said tensioning plate 8, which is formed by a part piece 8a secured to the casing 3 and a movable part piece 8b provided with said tensioning surface 9 on which it is guided and kept within a plane according to a direction 13 (FIG. 1) transverse to the swivel pin 5 and to the spring 6.
  • the plate's movable piece 8b is guided between two outer walls of the plate's fixed piece 8a.
  • the guiding surface 11 is formed on the fixed piece 8a, and it has a round edge 11a surrounded by the cord 7 to direct the cord end 7b towards the corresponding end of the spring 6 coaxially.
  • the tensioning plate's movable piece 8b on which cord 7 slides is guided within the fixed piece 8a and pushed in a direction 13 transverse to the swivel pin 5 by the adjusting screw threaded into a casing wall.
  • the spring 6 is set with a pre-tension for each appliance in accordance with weight "G" of the door 2 plus its cover panel, by means of the forward movement of the adjusting screw 10 which displaces the movable part 8b a separation distance "d" in said direction 13.
  • This movement “d” of the tensioning surface 9 is done with the door 2 closed and provides the spring 6 with a pre-tension, which modifies the characteristic curve during travel "A” of the resultant moment Ms of spring 6, between two curves of values Ms (max) and Ms (min), as is shown in FIG.3.
  • spring 6 is 180 mm long and the displacement "d" of the tensioning surface 9 in relation to the fixed part 8a for the pre-adjustment is 10 mm.
