Definitions

  • the present invention relates to a household appliance comprising a knob that is safely mounted to the panel.
  • Household appliances for example cooking devices, dishwashers and in particular washers/dryers, comprise a panel, a control unit and one or more than one knob that enable the functions thereof to be monitored and controlled by the user.
  • the knobs are directly attached to the shafts that are mechanically fastened to the switches on the control unit behind the panel by means of the housings on the panel or by means of an insert from the front of the panel.
  • the shafts that are connected to the knobs also move and the functions at predetermined positions depending on the user preferences, for example functions like in which program the laundries should be washed, at which rpm the spin-drying should be performed or at which temperature the wash water should be used, are enabled to be selected.
  • the knobs are mounted on the shaft that is connected to the control unit behind the panel from the front side of the panel for ease of production.
  • the knob is mounted on the panel by means of clawed structures, some tolerances are needed to be taken into consideration so that the shaft and the knob can be easily borne to each other. Therefore, a gap should be left around the clawed structures. While facilitating the rotation of the knob, these gaps weaken the resistance of the knob against exterior impacts and cause the knob to be operated in a loose manner. According to the international standards, the knob should pass the impact test, therefore, it should be ensured that the knob does not dislodge due to the impact imparted.
  • the aim of the present invention is the realization of a household appliance comprising a knob that is easily mounted and safely fixed onto the panel.
  • the household appliance realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a shaft that is borne by both an insert and a handle and that is mechanically connected to a control unit. Since the shaft fixes/locks the insert and the handle to each other, the insert and the handle cannot be separated without dislodging the shaft.
  • a first bearing and a second bearing that are configured so as to allow the shaft to pass therethrough are provided, and the shaft is configured so as not to rotate in both bearings independently of the bearings.
  • the insert and the handle are attached to each other so that the panel remains therebetween, as locking claws and locking protrusions engage with each other.
  • the first bearing and the second bearing are positioned to be end to end and allow the shaft to pass therethrough. After passing through the bearings, the shaft prevents the insert and the handle from moving relative to each other.
  • the shaft provides that the components interlock in an undetachable manner.
  • the knob cannot be detached from the household appliance unless the shaft is dislodged from inside the knob.
  • the dislodging of the knob under a load is prevented and both the perceptional quality is improved and the safety risk is eliminated.
  • Figure 1 - is the general front view of the panel of a household appliance.
  • Figure 2 – is the exploded cross-sectional view of the panel, the control unit, the shaft, the knob, the insert and the handle.
  • Figure 3 — is the front view of the insert and the handle when attached to each other.
  • Figure 4 is the view of the cross-section A– A in Figure 3.
  • Figure 5 — is the perspective view of the handle.
  • Figure 6 — is the perspective view of the insert.
  • Figure 7 — is the cross-sectional view of the insert and the handle that are fixed on the panel.
  • Figure 8 — is the cross-sectional view of the insert, the handle and the shaft that are fixed on the panel.
