Definitions

  • the present invention relates to a dishwasher comprising an automatic door opening mechanism.
  • the drying process is performed.
  • the door of the dishwasher can be partially opened automatically, the hot steam inside is discharged to the outside and the washed items are enabled to dry faster.
  • the door is partially opened automatically at the end of the washing and drying processes, applying less heat in the drying process is sufficient and thus, energy is saved. Opening the dishwasher door automatically, furthermore, prevents the steam getting cold from condensing and leaving stains on the washed items.
  • door opening mechanisms are used, that extend from the body towards the door and enable the door to be partially opened by pushing the door with the activation of devices such as solenoid or electric motor.
  • opening only the door is not sufficient, some amount of gap should remain between the door and the body to enable discharging of the steam outside.
  • EP1909631 discloses a spring that balances the weight of the door by applying a tensile force on the door of the dishwasher and an adjustment mechanism that adjusts the tension of the spring.
  • the aim of the present invention is the realization of a dishwasher comprising a door opening mechanism that partially opens the door automatically at the end of the washing program.
  • the door is enabled to be partially opened by means of the door latch that extends from the body towards the door at the end of the washing and drying processes such that a gap remains between the door and the body.
  • the dishwasher comprises a movement generator that triggers the door latch and a balancing mechanism that exerts force in the opposite direction to the opening direction of the door and prevents the door from falling due to its own weight.
  • the balancing mechanism comprises a spring, a connection cable connected to one end of the spring for stretching the spring and a hinge that connects the door to the body.
  • the spring is preferably of helical type and is fixed to the body from one end.
  • the dishwasher furthermore comprises a triggering mechanism that lets free the balancing mechanism operated by the control unit to balance the weight of the door so that the door is opened more at the end of the washing and drying processes.
  • the triggering mechanism comprises an actuator that is activated by the control unit at the end of the washing and drying processes, a triggering arm which the actuator contacts and a pulling cable that connects the triggering arm to the spring.
  • the movement of the actuator is transferred to the balancing mechanism by means of the pulling cable and the triggering arm.
  • the balancing mechanism decreases the force it exerts on the door, in the reverse direction to the opening direction of the door, thus the gap between the door and the body is increased at the end of the drying process.
  • the triggering mechanism comprises at least one spool that is disposed between the triggering arm and the spring, that changes the direction of the pulling cable, and whereon the pulling cable is wound.
  • the pulling cable can exert force on the spring in the desired direction by means of the spool.
  • the triggering mechanism comprises a carrier whereon the actuator, the triggering arm and the spool are disposed.
  • the carrier is box-shaped.
  • Figure 1 – is the detailed view of a dishwasher, a door latch and a movement generator.
  • Figure 2 – is the schematic view of a dishwasher.
  • Figure 3 – is the front view of a triggering mechanism.
  • the dishwasher (1) comprises a body (2); a door (3) that provides access into the body (2) and opens from the top downwards by rotating around a horizontal axis; a door latch (4) that provides the locking of the door (3); a movement generator (5) that enables the door (3) to be partially opened by being pushed at the end of the washing and drying processes so that a gap remains between the door (3) and the body (2), and a balancing mechanism (6) that is on the body (2) and that balances the weight of the door (3) by exerting force on the door (3) in the direction opposite to the opening direction of the door (3).
  • the movement generator (5) is preferably is a linear movement generator like a solenoid or electric motor and enables the door (3) to be opened by exerting the amount of force only sufficient for releasing the door latch (4) from its housing on the door (3).
  • the dishwasher (1) of the present invention comprises a triggering mechanism (7) that changes the gap between the door (3) and the body (2) by triggering the balancing mechanism (6) at the end of the washing and drying processes.
  • the balancing mechanism (6) activated by means of the triggering mechanism (7) at the end of the washing and drying processes decreases the amount of force it exerts on the door (3) in the direction opposite to the opening direction of the door (3). Thus, the gap between the door (3) and the body (2) at the end of the drying process is increased.
  • the balancing mechanism (6) comprises a hinge (14) that connects the door (3) to the body (2), a spring (15) that pulls the door (3) towards the body (2) by applying pulling force on the hinge (14) and a connection cable (13), one end of which is connected to the spring (15) and the other end to the hinge (14).
  • the direction and tightness of the connection cable (13) can be adjusted by a perforated cylindrical structure along its axis.
  • the triggering mechanism (7) changes the pulling force the balancing mechanism (6) applies on the door (3) by triggering the spring (15).
  • the spring (15) that is fixed on the body (2) from one end balances the weight of the door (3) by applying pulling force on the door (3) when the door (3) opens.
  • the spring (15) is triggered by the triggering mechanism (7), the pulling force exerted by the balancing mechanism (6) on the door (3) is decreased.
  • the door (3) is partially left free and the door (3) is enabled to move away from the body (2) by its own weight.
  • the triggering mechanism (7) comprises an actuator (8) that is activated at the end of the washing and drying processes, a triggering arm (9) pivotally connected to the actuator (8) and a pulling cable (10), one end of which is connected to the triggering arm (9), and the other end to the balancing mechanism (6).
  • the actuator (8) is operated at the end washing and drying processes by the control unit, pushes the triggering arm (9) it contacts and rotates the triggering arm (9).
  • the pulling cable (10) mounted to the triggering arm (9) is stretched and the stretched pulling cable (10) pulls the spring (15) connected to its other end.
  • the balancing mechanism (6) allows the door (3) to fall by its own weight and opens the door (3) some more.
  • the steam inside the body (2) is discharged to the outside environment easily.
  • the triggering mechanism (7) comprises at least one spool (11) that is disposed between the triggering arm (9) and the spring (15), that changes the direction of the pulling cable (10) and whereon the pulling cable (10) is wound.
  • the spool (11) By means of the spool (11), the force that is exerted on the pulling cable (10), independently from the position of the triggering mechanism (7) inside the body (2), is directed to the balancing mechanism (6).
  • the triggering mechanism (7) comprises a carrier (12) whereon the actuator (8), the triggering arm (9) and the spool (11) are disposed.
  • the carrier (12) By means of the carrier (12) a more compact structure is obtained and the triggering mechanism (7) occupies less space inside the body (2).
  • the movement generator (5) opens the door (3) by applying the amount of stroke sufficient for releasing the door latch (4) from the door (3) housing. The triggering mechanism (7) enables the door (3) to become ajar after the door (3) is opened.
  • the balancing mechanism (6) that is activated by the operation of the triggering mechanism (7) enables the door (3), opened by energizing of the movement generator (5), to become free and become sufficiently ajar such that steam discharge is allowed.
  • the positions of the triggering mechanism (7) and the balancing mechanism (6) inside the body (2) and/or the spring constant (k) of the spring (15) which is a part of the balancing mechanism (6) can be changed by the producer and the door (3) is enabled to be opened in the desired amount.
  • the door (3) is opened automatically by means of the movement generator (5) and the door latch (4) at the end of the washing and drying processes.
  • the amount of gap predetermined by the producer is enabled to remain between the door (3) and the body (2) when the balancing mechanism (6) is triggered by the triggering mechanism (7) at the end of the washing and drying processes, thereby increasing the drying effectiveness of the dishwasher (1).
  • the spring (15) is compressed in situations where the user tries to close the door (3) when the door (3) is partially open and thus the door latch (4) is not strained.
