Definitions

  • the invention relates to a lockable device for actuating an electronic component according to the preamble of claim 1, wherein the electronic component is arranged in the interior of an electrical device, with an externally operable control element, which with a housing hood of the device that can be partially delimited the interior of the electrical device is releasably lockable, and with an interior coupling element for transmitting a rotary movement of the control element to the electronic component, and an electrical device.
  • Rotatable switches or controllers are used in various embodiments, in particular in the field of household appliances. These serve as input means for the user and are usually located on an outer housing wall of the device. In order for these controls to function reliably as many applications as possible, they are usually secured against unintentional dismantling by means of locking hooks or additional screw connections.
  • locking hooks or additional screw connections In order for these controls to function reliably as many applications as possible, they are usually secured against unintentional dismantling by means of locking hooks or additional screw connections.
  • Locks or additional screw connections are more flexible in terms of maintenance and repair work, but must be installed through additional assembly steps so that the assembly effort increases and thus the production costs are higher.
  • an operating element which is attached to an axis of rotation.
  • the operating element has a leaf spring in the cylindrical axis of rotation receptacle, which engages in a corresponding groove made in the axis of rotation and thus makes it difficult or inadvertent to inadvertently remove the operating element.
  • the axis of rotation connects the control element to an electrical component. Depending on the version of the tongue and groove connection, it is necessary to dismantle the Control elements for maintenance or repair purposes only difficult or no longer possible.
  • the DE 299 05 269 U1 represents an operating unit for commissioning electrical household appliances.
  • the operating unit is constructed in several parts.
  • a base body is connected to a water valve by means of a flange sleeve.
  • a rotary toggle establishes a direct mechanical connection to the base body and thus to the water valve via teeth and locking means.
  • the components of the multi-part control unit are held together using classic locking connections. An additional safeguard against unintentional loosening of the locking connections is not provided here.
  • the DE2636920A1 discloses a locking device for an operating button with a tubular, compressible at least in a radial direction, guided in a bearing bore, which carries at least one locking element.
  • the tubular approach serves to receive a shaft.
  • the object of the invention is to provide a secure device for actuating an electronic component in an electrical device, which is secured in the assembled state against unintentional dismantling, but can be unlocked and dismantled again without additional effort. Furthermore, it is an object of the invention to provide an electrical device with the secure device.
  • a lockable device for actuating an electronic component, which is arranged in the interior of an electrical device, has an externally actuable control element, which can be releasably latched to a housing hood of the device, which can partially limit the interior of the electrical device.
  • a coupling element of the device for transmitting a rotary movement of the operating element to the electronic component is arranged on the interior side.
  • the coupling element in the installed state of the housing hood blocks the releasable latching of the control element with the housing hood.
  • the interlocking between the control element and the housing cover is blocked by the coupling element by means of a positive engagement of the coupling element on the control element in the assembled state.
  • the latching on the control element can be released, so that it can easily be connected to or detached from the housing hood.
  • the control element is secured by installing the housing cover and is released after the housing cover has been removed. An accidental disassembly of the control element is thus prevented, at the same time the control element can be subsequently removed without a lot of work. Furthermore, no additional assembly steps are required, both in the manufacture and in the repair.
  • the operating element has a hollow cylindrical rotary shaft section with at least one latching hook which detachably and rotatably latches into a corresponding recess made in the housing hood.
  • This measure allows the control element to be rotatably arranged on the housing hood and can be assembled or disassembled together with the housing hood.
  • the latching hooks are preferably designed such that the control element and the housing hood can be detached from one another without additional tools or effort.
  • the at least one latching hook is arranged on the hollow cylindrical rotary shaft section of the operating element and projects with a latching lug in the radial direction beyond the hollow cylindrical rotary shaft section.
  • the at least one latching hook can be designed, for example, integrally with the hollow cylindrical rotary shaft section of the operating element and project radially therefrom.
  • the at least one latching hook can also be introduced as a separate component in the hollow cylindrical rotary shaft section.
  • the recess made in the housing hood can preferably be circular.
  • the coupling piece protrudes at least in sections into an inner region of the hollow cylindrical rotary shaft section of the operating element to prevent a radially inward movement of the at least one latching hook.
  • the latching hooks protrude radially from the hollow cylindrical rotary shaft section of the operating element, they have to deform elastically when the operating element is removed from the housing and thus have to be pressed into the inner region of the hollow cylindrical rotary shaft section of the operating element.
  • the at least one latching hook is arranged on the hollow cylindrical rotary shaft section of the operating element and extends with its latching lug radially inward into the inner region of the hollow cylindrical rotary shaft section.
  • the at least one latching hook can also be made integrally with the hollow cylindrical rotary shaft section of the operating element.
  • the locking hook protrudes into the inner region of the hollow cylindrical rotary shaft section.
  • the recess made in the housing hood can preferably be circular, the housing hood additionally has a quasi-axis which projects into the inner region of the hollow-cylindrical rotary shaft section for the purpose of latching.
  • the coupling piece at least in sections engages around the hollow cylindrical rotary shaft section of the operating element to prevent a radially outward movement of the at least one latching hook.
  • an axis-shaped receptacle projects into the inner region of the hollow-cylindrical rotary shaft section and a snap-in connection is made with the control element.
  • the control element remains rotatable despite locking and can be released from the locking with little effort as long as the housing cover is not mounted on the electrical device.
  • the coupling element on the interior side is brought into contact with the outer lateral surface of the hollow-cylindrical rotary shaft section of the operating element.
  • the latching hook is given the necessary space for yielding, so that it is no longer possible to release the latching as long as the coupling element is in contact with the hollow cylindrical rotary shaft section of the operating element.
  • the at least one latching hook arranged on the hollow cylindrical rotary shaft section has a stop opposite to its latching lug.
  • the stop can serve on the one hand as a contact surface for the coupling element and on the other hand as a possible compensation for component and / or assembly tolerances.
  • the stop is preferably opposite the latching hook surface, which contributes to the latching. If latching hooks protrude, for example, from the hollow cylindrical rotary shaft section of the operating element, the stops of the latching hooks are located in the inner region of the hollow cylindrical rotary shaft section of the operating element.
  • the at least one latching hook arranged on the hollow cylindrical rotary shaft section has at least one guide bevel.
  • This measure allows the control element to be installed with little effort.
  • the snap hooks for easy removal of the control element from the housing cover can also have guide slopes with a larger slope in the removal direction.
  • the latching hooks also have guide bevels in the area of the stops, which guide the coupling element specifically to the intended place when the electrical device is being installed.
  • the securable device in order to transmit a rotary movement of the operating element, it is positively connected to the coupling element. Due to the positive connection between the control element and the coupling element, every rotational movement of the control element is transmitted directly to the coupling element.
  • the form fit is preferably over one or more axial recesses made in the coupling element, into which corresponding webs of the control element engage.

  • a projection 18 extends from the end wall 10 parallel to the axis of rotation D and has a greater axial extension than the hollow cylindrical rotary shaft section 12 with the latching hooks 14.
  • the coupling element 16 is directly or indirectly connected to the electronic component 2 on the inside of the housing, so that a rotational movement of the coupling element 16 is transmitted to the electronic component 2. It has a central receiving groove 20 for the pushing reception of the projection 14 of the operating element 6 and a ring section with an outer circumferential bearing surface / ring surface 22 for blocking a release movement of the latching hooks 14.
  • FIG 2 a section through the first embodiment of the lockable device 1 according to the invention for actuating an electronic component 2 in the assembled state is shown.
