  • a comfortable handling can be achieved.
  • FIG. 1 shows a household appliance formed by an oven with a domestic appliance device having a pivotally mounted in pivot directions 14, 15 door unit 10, which is shown in a disconnected state.
  • the domestic appliance has an oven muffle 46, which is arranged in a household appliance housing 44 and encloses a cooking chamber 48 on five sides. On a front side of the household appliance, the cooking chamber 48 can be closed by the door unit 10.
  • the domestic appliance has a storage space 40 arranged underneath the oven muffle 46, into which the door unit 10, guided via a door storage unit 42 of the domestic appliance device, can be retracted to a large extent, ie down to the handle, by means of a pivoting movement and a subsequent sliding movement in a horizontal direction is.
  • the door storage unit 42 has two basically corresponding, each with lateral end faces of the door unit 10 in the pivot directions 14, 15 fixed and movably coupled in a surface extension direction 38 of the door unit 10 bearing units 12, wherein only one of the two storage units 12 is shown.
  • the storage units 12 have to the movable coupling with the door unit 10 in each case two rollers 54, 56, which in opening the door unit 10 in grooves 58 of the door unit 10, which delimit the door unit laterally in a front view, are performed.
  • the bearing units 12 are rotatably mounted about an axis 34 which extends in a horizontal direction perpendicular to the surface extension direction 38.
  • the surface extension direction 38 runs in a closed door unit 10 in a vertical direction when the domestic appliance is arranged in an operating position. Furthermore, the door storage unit 42 has a relative to the household appliance housing 44 for receiving a portion of the weight of the door unit 10 mounted bearing device 50, which is guided in the large-scale sinking of the door unit 10 in the storage space 40 of a guide slot 52 which is fixed to the housing.
  • the Figures 2 and 3 show incompletely mounted partial views of the domestic appliance with the storage unit 12, a bearing means 30 to the rotatable mounting of the storage unit 12 and a spring unit 16 of the household appliance.
  • the spring unit 16 exerts a force on the bearing unit 12. Due to the rotatable mounting of the bearing unit 12, this force causes a torque which acts both on the bearing unit 12 and, due to the coupling of the bearing unit 12 and the door unit 10 in the pivoting directions 14, 15 on the door unit 10.
  • the bearing unit 12 has a control contour 18, which determines the force in an operating state and upon opening or closing of the door unit 10 due to a position of the door unit 10.
  • the position of the door unit 10 is uniquely determined by an angle which the surface extension direction 38 forms with a vertical in an operating position of the domestic appliance.
  • the force is caused by a designed as a compression spring spring means 24 of the spring unit 16, which is fixed at a first end 60 to the bearing means 30 which is mounted fixed to the housing.
  • the spring means 24 is attached to a second end 62 opposite the first end 60 to a bracket member 32 of a holding means 28 which is rotatably mounted about an axis 64 of the bearing means 30, wherein the axis 64 is parallel to the axis 34.
  • a straight line 68 which extends through the center of mass of the spring means 24 and extends along a main direction of extension of the spring means 24, intersects and is perpendicular to the axis 34.
  • the support means 28 rotatably supports a roller-formed power transmission means 26 rotatably about an axis 66 which is also parallel to the axis 34.
  • the power transmission means 26 is disposed between the yoke member 32 and the control contour 18 and contacts the control contour 18.
  • the retaining means 28 is a generated by the spring means 24 and received by the bracket member 32 pressure to the power transmission means 26 which exerts a pressure on the control contour 18 and thereby exerts the force on the door unit 10 by means of the bearing unit 12.
  • the power transmission means 26 is constantly pressed by the spring means 24 to the control contour 18, so that the force transmission means 26 rolls on pivoting on the control contour 18 and is guided in this manner by the control contour 18.
  • the control contour 18 determines the torque which is exerted by the spring means 24 on the door unit 10.
  • the spring unit 16 has in addition to the spring means 24 designed as a tension spring spring means 25 25 which exerts a torque on the bearing unit 12 by means of a yoke member 98.
  • the tension spring 70 is stretched and stores the positional energy of the door unit 10.
  • FIG. 4 3 shows a portion of the bearing unit 12 in a side view along the axis 34.
  • the control contour 18 extends over an angular range 74 of ninety degrees with respect to the axis 34.
  • the control contour 18 has a plurality of cams 20, 22 , 78 for adjusting the torque.
  • the power transmission means 26 is shown schematically in an operating position.
  • the force transmission means 26 abuts against surface points of the control contour 18, through which a common tangential plane 84 extends to a surface of the control contour 18.
  • a plane extending direction of the tangential plane 84 is parallel to the axis 34.
  • the tangential plane 84 is in FIG.
  • FIG. 4 shown as a straight line 80. Furthermore, in FIG. 4 a plane perpendicular to the main extension direction of the spring means 24, which along the straight line 68 (see FIG. 2 ) runs, shown as a straight line 86.
  • the straight lines 86 and 80 include at least one angle 88, which is less than thirty-five degrees, in each operating state.
  • FIG. 5 shows a graph with torques, which act on these depending on the opening angle of the door unit 10.
  • the opening angle is enclosed by the surface extension direction 38 with a vertical and has a size of ninety degrees when the door unit 10 is fully open.
  • a curve 90 indicates the course of the torque caused by the compression springs.
  • Another curve 92 indicates the course of the torque caused by the tension springs 70.
  • the sum of the curves 90 and 92 is represented by a curve 94.
  • the torque exerted by the gravity of the door unit 10 on the door unit is represented by a curve 96.
  • FIG. 5 is plotted on the abscissa of the opening angle in degrees.
  • the torque is plotted in Newton meters.
  • Positive values of the curve 96 assist in opening the door unit 10
  • positive values of the curves 90, 92, 94 assist in closing the door unit 10.
  • the values of the curve 94 are greater than the values of the curve 96 , which causes the entire torque acting on the door unit 10 to assist in closing the door unit 10.
  • the door unit 10 is therefore in the closed state with about thirty Newton to the home appliance housing 44 (see FIG. 1 ).
  • the torque values of the curve 94 are about the same as the torque values of the curve 96.
  • the door unit 10 is in a floating state in this opening angle range.
  • the values of the curve 94 are smaller than the values of the curve 96. This promotes opening of the door unit, the door unit 10 is accelerated. The kinetic energy absorbed by the door unit 10 causes the door unit 10 to be completely drawn into the storage space 40. An arranged in the storage space 40 damping means of the household appliance brakes the door unit 10 completely. The sum of the torques acting on the door unit 10 at ninety degrees opening angle has no effect on the position of the door unit 10. The sum is relatively small, whereby between the rollers 54, 56 and the door unit (see FIG. 1 ) creates a small friction.
  • the curve 90 in the range of seventy-five degrees of opening angle, a maximum torque caused by the spring means 24 is necessary in order to compensate for the torque caused by the gravity of the door unit 10 in a user-friendly manner.
  • the torque values of the curve 90 are relatively small to equalize the torques caused by the tension springs 70.
  • a steep drop of the curve 90 occurs. This is effected by the cam 22, which has a greater curvature than the remaining cams 20, 78 of the control contour 18.
  • Bei an opening operation of the door unit 10 the angle 88 assumes its maximum value when the power transmission means 26 rolls on the cam 22.
  • Curve 90 has a flat profile at zero degree opening angles and then drops steeply to a negative value at twenty degrees opening angle as compared to the curve of the curve between seventy-five degrees and ninety degrees. Further, in an angular range at twenty degrees, the curve 90 is relatively flat in a negative value range. This course of the curve 90 is realized by the cam 20.
