  • the knobs are connected by means of a shaft to an encoder on a control card disposed behind the control panel by means of housings on the control panel.
  • the knobs can be attached to the shaft directly or by means of an insert.
  • problems due to production tolerances and displacements occurring during the assembly, deviations may occur in the position of the shaft in the housing, and in this case problems such as erroneous operation of the knob and even failure of the knob to perform its function may occur. These problems result in user dissatisfaction and a decrease in the perceived quality.
  • the aim of the present invention is the realization of a household appliance comprising a knob the operational flaws of which are eliminated.
  • the household appliance realized in order to attain the aim of the present invention, explicated in the claims, comprises a control panel; a control card that is positioned behind the control panel and that controls the operational status of the household appliance; a knob that is disposed on the control panel and that can be moved by the user; a housing that is disposed on the control panel and whereon the knob is placed; a shaft with one end connected to an encoder on the control card and the other end extending out of the housing, and an insert that is mounted on the shaft and that enables the knob to be connected to the shaft.
  • the shaft moves together with the knob when the knob is rotated and enables the preferences received from the user by means of the knob to be transmitted to the control card.
  • the household appliance of the present invention comprises the insert that has an opening wherein the shaft is housed so that the shaft slides along a linear axis, and at least one connection element that is disposed on the insert and the knob and that enables the knob to be movably connected to and engage with the insert.
  • the insert can move on both the shaft and the knob and enables friction forces acting on the knob due to inclined or eccentric position of the shaft in the opening to be minimized.
  • the knob is enabled to operate without any errors without being affected from erroneous positioning of the shaft.
  • connection element provides the insert with the freedom of movement on the knob along an axis perpendicular to the longitudinal axis of the opening.
  • eccentricity of the shaft in both horizontal and vertical directions can be tolerated.
  • connection element comprises at least one extension that extends outwards from the insert perpendicularly to the sliding axis of the shaft in the opening, and at least one slit that is arranged on the knob and wherein the extensions enter when the knob is placed on the insert.
  • the extensions move in the slit during the movement of the insert on the knob. Thus, the movement of the insert on the knob is guided.
  • connection element comprises at least one protrusion that is disposed on the knob, and at least two extensions that are oppositely disposed on the insert and that extend outwards from the insert perpendicularly to the sliding axis of the shaft in the opening.
  • the protrusion enters between the extensions and provides the insert with the freedom of movement in a single axis.
  • the shaft has a D-shaped cross-section.
  • the flat side of the shaft bears against the surface of the insert surrounding the opening and thus the shaft is prevented from being rotated independently of the knob.
  • the knob has a wall that, when the knob is placed on the insert, extends toward the control panel so as to surround the insert, and the wall is provided with more than one claw that extends outwards from the edge of the wall perpendicularly to the wall.
  • the knob is fixed on the control panel by passing the claws through the housing so that the claws contact the control panel from the rear side thereof. Thus, the knob is prevented from detaching from the control panel.
  • the knob is enabled to perform its function without any errors in the cases where the shaft is not positioned properly in the opening due to production tolerances and any displacement occurring during the assembly. Moreover, by means of the present invention, the knob is prevented from inclining during the operation in the case when the shaft is mounted in an inclined manner.

  • the knob (7) is connected to the insert (8) by means of the connection element (10), and the connection element (10) enables the insert (8) to move on the knob (7).
  • the insert (8) moves by sliding on both the shaft (5) and the knob (7) while the knob (7) is rotated and enables the effects of any assembly defects of the shaft (5) on the movement of the knob (7) to be eliminated.
  • the knob (7) is enabled to be always rotated in full circle.
  • connection element (10) enables the insert (8) to move on the knob (7) perpendicularly to the movement direction of the shaft (5) in the opening (9).
