The invention relates to a household appliance, such as refrigerator, stove, washing machine, dishwasher, etc., containing, by Mansory, switches, motors, etc., the connecting cable which contains the employee for protective grounding wire, and which includes at least one space - case, which contains the completed conductive parts that can be a contact person, such as made of electrically conductive material of the side walls, struts, door, etc., at least mostly, electrically interconnected and electrically grounded.

For appliances, the prescription is that they are made of electrically conductive material of the housing which contacts the person and which in the case of insulation can be energized continuously and reliably in contact with protective contact instrument plug.

To do this, in the field of refrigeration appliances has long been a technical level, to earthed mains cord compressors contacted his case with a grounding wire, which, in turn, electrically connected with the carrier compressor tire. The latter at the expense of their installation with made of sheet steel side walls and through them electrically in contact with other interfaces causes problems, in particular, the connection between the load-bearing rail and side walls, as for manufacturing, the latter applies pre-coated material, called "covered roll of sheet steel, the surface of which is provided with a lacquer layer, which itself prevents electrical contact between the bearing rail and lateral walls in the case when both of the connected element are pressed to each other only through a mechanical coupling. To resolve this problem, contact the designers went to use through the varnish layer of structural elements, for example, so-called washers, or provided for grounding details with claw-like projections so that when the production batch of goods is always to create a reliable ground connection between conductive and related parts of the body. Such additional parts are considerably more difficult, however, the Assembly process and bring with them to the same problem that functionally reliable communication to a certain extent depends on the thoroughness of the staff.

Further, in the field of dishwashing machines of the prior art is onasi corps false flags, through the insertion sleeve is attached to the protective wire, which type of cable harness with different, if necessary, along the length of the protective wires away from the Central place of the earth in the body of the instrument. Here, however, due to the direct contact of the individual parts under voltage, under certain circumstances, in the case of insulation, protective wires always provided reliable grounding of these details, however, the manufacture of cable harnesses, on the one hand, and their installation in the unit, on the other hand, are the reason for the high cost of production.

From US 5676438 known household appliance containing at least one detachable supporting member for operating from a network of structural elements, the connecting wire each of which contains the employee for protective grounding wire, and which includes at least one storage space body, which contains the completed conductive part, which contacts the person, such as made of electrically conductive material of the side walls, struts, door, etc., at least mostly, conductive Saitova the appliance is simple constructive measures reliable, addresses the deficiencies of the prior art electrical grounding is made of electrically conductive material of the structural details of such a device.

The task of the household appliance, containing at least one detachable supporting member for operating from a network of structural elements, the connecting wire each of which contains the employee for protective grounding wire, and which includes at least one storage space, the body, which contains the completed conductive part, which contacts the person, such as made of electrically conductive material of the side walls, struts, door, etc., at least mostly, electrically interconnected and electrically grounded according to the invention is solved by what bearing element contains at least two pritvorenih contact element which, when the fixed position of the bearing element on the housing or parts mounted for engagement with the slots on the housing or parts of the power circuit and/or circuit material to provide conductive contact with the body or parts.

The contact elements should be implemented in longitudinal section triangular.

The contact elements can be formed by bending and cutting of the bearing element in its segment.

Nests in the bodies or parts are rectangular, with the possibility of deformation during penetration of the contact elements.

Thanks to the solution according to the invention without additional electrically contacting parts only due to the mounting and fastening of a bearing element provided reliable electrical contacts and thereby grounding of parts under voltage in case of damage to the insulation. By reducing the number of parts is additionally significantly increased the degree of automation appliance, and at the same time while maintaining high quality production significantly reduced the requirement for care staff and thereby reduced random errors in the Assembly.

Particularly reliable contact elements in contact with the bearing element, in particular when it is covered at the site of contact varnish, etc., if according to a preferred form of execution of the object of the invention is provided, h is manipulirovanie and is therefore particularly economical manufacture of the bearing member arises when according to the following preferred execution of the object of the invention provides that the contact elements formed on a support element for a single whole with him.

According to another preferred form of execution of the object of the invention, it is provided that the contact elements are made in a triangular longitudinal section and in the docked state is able to interact with the slots in the housing or parts of the power circuit and/or circuit material.

Due to the triangular execution of the contact elements of the socket, which may have, for example, rectangular, square or circular cross-section holes when mounting the carrier to a certain extent, deform free lateral sides of the contact elements, resulting as a consequence of the process in places of contact of the contact pair of non-conductive layers, such as lacquer layers, corrosion layers, etc. are securely oskablivajutsja, and thus due process of installation without additional measures ensures reliable electrical contact and, thus, meet the standards of the Society of German electrical engineers grounded connection of the contact elements with the body or detaili according to the following preferred implementation of the subject invention is provided, that the contact elements are formed by bending and cutting of the support member of its segments and their bending. Under bending logging should understand the felling of the contact elements of the support member and curl up.

Due to this technique of forming the contact elements, such as bending, cutting, occurs besides in place of their separation from the carrier specific grata, which contributes blade scraping action triangular in longitudinal section of the contact elements when the penetration into the socket in the housing or parts.

According to another preferred form of execution of the invention provides that the slot in the housing or parts made rectangular and the penetration of the contact elements can be deformed.

This provides not only a reliable engagement of the bearing member through the contact elements with the body or parts, but due to the rectangular execution of nests is also guaranteed that the triangular contact elements even in the so-called worst case installation can always be securely connected through the elongated run out of sockets.

One of the most viable options espaa least one useful space, a heat insulating casing, which contains the completed conductive part, which contacts the person, such as made of sheet steel side walls or similar, and engine compartment to accommodate the refrigeration compressor, resting on a grounded carrier bus, which is electrically connected through the side wall with the other components, according to the invention is characterized by the fact that the mounting rail as bearing element has at least two contact elements, which in the docked state support rails on the body or in the side walls installed with the possibility of electrically conductive engagement with the side walls.

Below the invention is illustrated by the example of a household refrigerator, simplistically depicted in the attached drawings, on which:
