Definitions
- the invention relates to a household appliance, such as a cold appliance, a stove, a washing machine, a dishwasher or the like, with at least one detachable support element for electrically operated components, such as compressors, switches, motors or the like, the electrical connection line of which serves as a protective earth conductor and with an at least one usable space housing, which has electrically conductive and touchable components such as side walls made of electrically conductive material, struts, a door or the like, which are at least largely electrically connected to one another and electrically grounded
- connection between the mounting rail and the rare walls in particular poses problems because a precoated, referred to as "Coil-Coating Steel Sheet” material is used, the surface of which is provided with a lacquer layer, which in itself prevents electrical contact between the mounting rail and the rare walls in the event that the two connection partners are only you are pressed against one another by a mechanical connection
- a precoated, referred to as "Coil-Coating Steel Sheet” material is used, the surface of which is provided with a lacquer layer, which in itself prevents electrical contact between the mounting rail and the rare walls in the event that the two connection partners are only you are pressed against one another by a mechanical connection
- components which penetrate the lacquer layer such as so-called toothed disks or especially for to use the earthing provided components with claw-like attachments in order to always provide a secure earthing connection between the electrically conductive and touchable housing parts in the production of high-volume items of consumer goods.
- additional components make the assembly process considerably more difficult and also involve the problem that the functionally
- the invention has for its object to provide a reliable, the disadvantages of the prior art avoiding electrical grounding of the components made of electrically conductive material in a household appliance according to the preamble of claim 1 with simple, constructive measures
- the support element has at least two contact elements which are able to interact with the housing or the components in an electrically conductive manner when the support element is attached to the housing or the components
- the contact elements contact the carrier element particularly reliably, in particular if the latter is coated with lacquer or the like at the contact point, if, according to a preferred embodiment of the object of the invention, it is provided that the contact elements are designed as contact tips
- the contact elements are triangular in longitudinal section and are able to interact in a force-fitting and / or material-locking manner with receptacles on the housing or the components
- the receptacles which can have, for example, a rectangular, square or circular opening cross section, are deformed to a certain extent by the free flanks of the contact elements when the support element is mounted, as a result of which, as a result of this process, non-conductive layers at the contact points between the contact partners such as lacquer layers, corrosion layers or the like are safely scraped off and thus a safe electrical contact and thus a VDE-compliant earth connection of the contact elements to the housing or the components is already guaranteed by the assembly process without additional measures
- the contact elements can be produced particularly inexpensively and easily for large-volume production if, according to a next advantageous embodiment of the subject of the invention, it is provided that the contact elements are formed by cutting and bending support element sections from the support element. Cutting bending means that the contact elements are separated and raised from the support element understand
- the forming technology of the cutting bending of the contact elements also creates a certain degree of separation at their point of separation from the support element, which - 4 -
- the receptacles on the housing or the components are rectangular and are deformed when the contact elements penetrate
- the invention can be used particularly expediently in the case of a cold appliance with a warm-insulating housing which accommodates at least one useful space and which comprises electrically conductive and touchable components, such as side walls made of sheet steel or the like, and a machine room for receiving a cold medium compressor which rests on an electrically grounded mounting rail which is electrically conductively connected to the other components via the side walls if, according to a last preferred embodiment of the object of the invention, it is provided that the mounting rail is designed as a carrier element according to one of Claims 1 to 5 and each of the side walls according to Claim 6
- Fig. 1 simplifies a household cooling device with a machine room saved through a floor pan for receiving a compressor resting on a mounting rail and two sheet steel housing walls connected to the mounting rail in a spatial view from behind - 5 -
- FIG. 3 shows a detail in a sectional view of the floor pan and the side wall according to FIG. 2 in the jointed state and the mounting rail in the unsecured state and
- FIG. 4 shows a section in section of the floor pan, the side wall and the mounting rail according to FIG. 3, in the joint state
- FIG. 1 a purely schematically illustrated household cold appliance 10, shown as a table-top device, is shown in a spatial rear view, the heat-insulating housing 11 of which has a door 12 on its front side and a niche-like free machine room 13 on its rear side opposite the door 12, which is from the rear side of the housing 11 is accessible.
- the machine room 13 is freed up by a base trough 14, for example made of one piece from plastic injection molding, which limits the machine room 13 both for heat insulation of the housing 11 and laterally
- the base trough 14 has molded-on receptacle 16 on its side walls 15 (only one of which is shown in the broken state), which are accessible from the underside of the side walls 15 facing the installation level of the device 10
- the mounting bosses 16 are provided with cylindrical fixing domes 17 (only one is visible) which, like the receiving boss 16, are accessible from the underside of the side walls 15 and are used for the self-tapping insertion of fasteners 18 designed as screws
- the support rail 20 is electrically conductive to the housing of the refrigerant compressor 19 via an earth line 21 connected, which in turn is grounded via its mains connection line (not shown).
- the support rail 20 has a support web 22 which is rectangular in plan view and on which, in order to reinforce it and thus to improve its wearing properties, it is provided with downward angled portions 23 along its longer rectangular sides Rectangle-
- the support web 22 rarely has cut-out prism-like contact elements 24, which are triangular in longitudinal section.
- contact elements 24 are angled out of the plane of the support web 22 on the side opposite the angled portions 23 and parallel with their free prism legs 26 converging to a cutting-like edge 25 arranged to the shorter rectangle side of the mounting rail 20
- the side walls 30 are formed in the form of a flat shell, the shell bottom 31 of which serves as a side visible surface of the side walls 30 and whose shell walls 32, which are produced by angling, encompass the warm, insulating housing body 11 on the side edge portions thereof Elongated holes 33 are equipped, the longer sides of which run parallel to the shell bottom 31. Between the elongated holes 33, the shell walls 32 facing the installation level have rectangular recesses 34 spaced apart from one another, the longer rectangular sides of which are also oriented perpendicular to the shell bottom 31
- the side walls 30 made of sheet steel are connected on the door side to cross struts, not shown, made from sheet steel, referred to as end plates, which, like the side walls 30, are grounded via the grounding line 21 fixed to the mounting rail 20 the elongated holes 27 on the supporting web 22 and the elongated holes 33 on the rare walls 30 penetrating fastening means 18 are fixed to the floor pan 14 and are connected in an electrically conductive manner to the two rare walls 30.
- the electrical connection between the support rail 20 and the rare walls 30 is produced by the contact elements 24, which are inserted into the recesses 34 when mounting the mounting rail 20 in the direction of the arrow (FIGS.
