Definitions

  • the present invention relates to a household appliance.
  • a control panel on a home appliance conventionally hides one or more controllers of the appliance and carries on its front panel controls such as knobs for adjusting the controls.
  • Such control panels can be put together in different ways.
  • a known procedure is to first set up a knob on a shaft of the controller and then push the knob from the back of the control panel forth through an opening thereof.
  • the disadvantage here is that between the knob and the front panel usually a gap remains open, can penetrate through the contaminants and moisture in the device.
  • the front panel and then the controller must be mounted first, but the front panel restricts the accessibility of the controller mounting space.
  • An alternative approach is to first mount the regulator and faceplate so that a shaft of the regulator extends through or is accessible through an opening in the faceplate, and then attach the knob to the shaft from the outside. Again, it is difficult to put the individual components together so that no moisture can penetrate into the device. Although the knob can be mounted to completely cover the opening of the faceplate, it is difficult to reliably close a gap between the face of the faceplate and a backside of the knob, especially when the knob is locked to the shaft by latching to prevent the passage of dirt or moisture.
  • Object of the present invention is to provide a control panel for a household appliance, which is easy to assemble and yet provides good security against the ingress of contaminants into the device via an opening in the control panel.
  • Another object is to provide a control panel for a refrigeration device, which allows a convenient and quick installation of a regulator, in particular a thermostat, without the risk of damaging the latter.
  • a household appliance with a control panel, which is equipped with a front panel, arranged on a front side of the front panel knob and connected to the knob, arranged on a rear side of the front panel controller in which the knob into a recess Having the front engaging shaft, the shaft carries first locking means and in the recess second locking means are received, which cooperate positively with the first locking means when the shaft is inserted into the recess.
  • the two cooperating locking means keep the knob stable position in a predetermined position, regardless of any interaction with the controller.
  • the first locking means may be formed as a radially outwardly projecting from the shaft collar or radially inwardly directed by the shaft groove
  • the second residual means may be formed as arranged in the recess locking tongues.
  • the front panel serves as a reference for locking the knob, so that despite possible tolerances in the arrangement of - not necessarily directly attached to the front panel - controller with respect to the front panel of the knob reliably locked in such a position on the front panel that it protects its opening well from moisture and impurities.
  • the shaft is preferably attached to a control shaft of the controller rotatably attached.
  • shaft and control shaft can be displaced relative to each other in order to compensate for tolerances in the placement of controller and base plate in relation to each other.
  • the control shaft can pass through a passage of the control panel play, to simplify, especially in the presence of multiple controllers in a device and behind the same front panel, the placement of the front panel after mounting the controller in the device.
  • the collar is preferably provided at an end of the shaft facing the governor to impart increased strength to torques to be transmitted to the governor and prevent tearing of the shaft at high load.
  • the tongue preferably extends radially from the root toward the shaft and toward the regulator in the axial direction. This arrangement results in that when pulled on the knob in the axial direction, the tongue is subjected to compression. This compression can provide the tongue with a high resistance, even if otherwise their material thickness is low and their flexibility is high.
  • a plurality of tongues may be arranged distributed around the shaft, preferably two tongues are diametrically opposed on either side of the shaft.
  • the recess has an inner portion receiving the latching tongue and an outer portion having a larger diameter than that of the inner portion, and that an outer wall of the rotary knob in the Outside section of the recess engages.
  • a similar labyrinth sealing effect can be achieved by means of a curved rib disposed concentrically with the shaft on the front panel, which engages in a rear recess or annular groove of the rotary knob.
  • Both the rear recess of the knob and the rib of the front panel can also serve as a guide for the rotational movement of the knob; in this case, it is not necessary for the rib to form a closed ring.
  • the last-mentioned features may also be combined in the form that the rib is arranged in the outer portion of the recess.
  • the engagement of the rotary knob in the outer portion of the recess can also serve as a reference for fixing the controller in a direction perpendicular to its axis of rotation direction.
  • the attachment of the regulator to the frame may be playful in the direction perpendicular to the axis of rotation, and complete fixation of the regulator will not be achieved until the knob is attached.
  • Figure 1 is a partial perspective view of the body of a refrigerator as an example of an inventive electrical device.
  • Fig. 2 is a detail view showing a knob detached from the control panel;
  • Fig. 3 is a second detail view;
  • Fig. 4 is a plan view of the recess of the control panel without controller
  • Fig. 5 is a schematic section through the control panel.
  • Fig. 1 is a perspective view of the body of a built-in refrigerator.
  • a control panel comprises a front panel 1 which extends over the entire width of the front of the device above a storage room 2.
  • support elements 3 are provided, on each of which a hinge part for the suspension of a door, not shown here of the refrigerator can be fastened. In the closed position, the door not only covers the storage room 2, but also the entire control panel.
  • buttons 5, 6, for example, for setting the target temperature for the storage room 2 and a second storage space, not shown, of the refrigerator, and a button 4 are arranged, which is arranged behind the control panel 1 switch interior lighting of Storage room 2 is operated and keeps this switched off with the door closed.
  • Fig. 2 shows a section of the control panel 1 with the two knobs 5, 6 in a slightly different perspective.
  • the rotary knob 5 is shown in dissolved from the front panel 1 state, on the one hand to show the shape of the knobs 5, 6 and on the other hand a hidden in the assembled state of them depression 7 in the control panel 1.
  • the knobs 5, 6 each have a flat cylindrical, on its side facing the control panel 1 side hollow head 9 with a circular base plate 10 and extending around the base plate 10 outer wall 11.
  • a centrally projecting from the base plate 10 hollow shaft 12 carries on his free end a circumferential collar 13.
  • a head 9 facing the front of the collar 13 is tapered frustoconical.
  • the recess 7 is composed of two successive cylindrical sections, an outer section 14 with a depth of a few millimeters and an inner section 15 whose depth is a multiple of the depth of the outer section and whose diameter is significantly smaller than that of the outer section 14.
  • An opening 16 extends, as can be seen in particular in Fig. 4, diametrically across a rear wall of the inner portion 15 and over the cylindrical outer wall to the roots of two diametrically opposite spring tongues 17th
  • a piece of a housing of a thermostat regulator 18 is positively received in a central region of the opening 16, and a projecting out of this housing actuating shaft 19 of the thermostat extends through the opening 16 into the interior of the recess. 7
  • This arrangement allows a convenient and safe assembly of the refrigerator by first mounted on a frame of the device before attaching the front panel 1, the thermostat transversely to its control shaft 19 play. As long as the front panel 1 is not mounted, the location of the thermostat 18 is easily accessible. The thermostats 18 can therefore be easily mounted individually. The single installation makes it easier to avoid damage to a thermostatic capillary during installation, since only one capillary has to be handled simultaneously. Only when the front panel 1 is attached, the position of the thermostat 18 by the requirement that their housing is to engage positively in the opening 16, set exactly.
  • the hollow shaft 12 of the rotary knob 5 is positively plugged onto the control shaft 19. If after mounting the front panel 1, the knob 5 is attached, first enters the collar 13 in contact with the spring tongues 17 of the front panel 1 and pushes them apart and against the rear wall of the recess 7. Next, the outer wall 11 of the knob 5 moves into the outer portion 14 of the recess 7 a.
  • the intuitionabschitt 14 and the head 9 of the knob have the same diameter except for a required for easy rotation of the knob small undersize.
  • a circular arc-shaped rib 20 concentric with the adjusting shaft 19 engages in the annular space between the shaft 12 and the outer wall 11 of the rotary knob 5.
  • the spring tongues 17 pass through the collar 13 and engage at the frustoconical front side.
  • the knob 5 is thereby fixed to the front panel 1 in virtually all three spatial directions without play; a varying due to manufacturing tolerances or different models of the thermostat 18 used engagement depth of the actuating shaft 19 in the recess 7 does not affect the locking position of the knob 5.
  • the control shaft 19 has no contours on which the knob 5 could latch, or could prevent an axial displacement of the control shaft 19 and the shaft 12 against each other.
  • the axial position of the knob is determined solely by its engagement with the tongues 16 of the front panel 1 and with respect to the latter. This makes it particularly easy to use in the mass production of the refrigerator according to the invention thermostats of different manufacturers, which differ slightly in their dimensions and / or the shape of their housing, without having to be adjusted for any other parts.
  • the thermostat 18 For an exact placement of the thermostat 18, it is also not necessary that, as shown in Fig. 3, a part of its housing positively engages in the opening 16. Rather, the thermostat on the frame of the refrigerator across its actuating shaft even then still be playful; when the front panel 1 is already mounted.
  • the knob 5 When the knob 5 is plugged, the final position of the thermostat 18 automatically results in that the knob 5, in order to lock, must engage in the outer portion 14 of the recess 7, and that knob 5 and thermostat are moved together if necessary, to place the head 9 of the knob 7 exactly in front of the recess 7 and insert into the recess 7.
  • Fig. 5 shows a schematic section through the control panel of the refrigerator in the assembled state with mounted thermostat 18 and knob 5 in one of the Stellwelle 19 extending level.
  • the spring tongues 17 put the attempts to withdraw the knob 5 of the front panel 1 again, a considerable resistance ,
  • the knobs 5, 6 may be inextricably linked by latching to the front panel 1 with this; in the event that repairs to the thermostat 18 or other arranged behind the front panel elements are required, the front panel 1 can be removed together with the latched knobs 5, 6 and reassembled after completion of the repair.
  • the knobs 5, 6 can be removed again from the front panel 1, as in the first assembly of the refrigerator preassemble the thermostat play and only during assembly of the front panel 1 in With respect to this or even at the attachment of the knobs 5, 6 to be able to position with respect to the latter.
  • the spring tongues 17 are flexible enough to collapse under a tensile force exerted on the knob and elastically fold forward and thereby release the knob without being damaged.
  • screw holes 21 may be provided which allow with the help of engaging in the thread of the thermostat housing 18 screws play-free, releasable fixation of the thermostat on the front panel 1.
