The invention relates to a domestic appliance
comprising a plurality of functional components, which with lines
such household appliance
is, in particular designed as a laundry care machine such as washing machine
or dryer or as a dishwasher,
well known. Each of these home appliances has a variety of
Functional components, which in the operation of the household appliance for given
Purpose to work together. It is also common practice to use conduits containing the functional components
in particular electrically interconnect, to individually vorfertigbaren
and the final production of such household appliances zulieferbaren line trees together
A wiring harness that can be used in such a household appliance is in the DE 100 61 240 A1
described. Accordingly, a wiring harness is a prefabricated unit of numerous, in particular equal length cables, which unit can be mounted in a domestic appliance, in particular in a corresponding, also described in the cited document cable receiving device. From the DE 100 63 682
goes out a holder for mounting a wiring harness.
The invention to be described below is based inter alia on
the task, according to previous
Time-consuming and cost-intensive connection of the functional components in
a household appliance
to simplify each other.
This object is achieved by a domestic appliance comprising a multiplicity of
Functional components which are interconnected with cables

This is according to the invention
configured and the functional components are arranged such
that the lines between the functional components as a star-shaped line system
are in which the node component forms a center of
which all lines go out and on which all other functional components
are connected. It can

it comes down to one of the only node component appropriate positioning
in the present case also primarily consisting of electrical lines
Line system is described, the invention is not
limited to this.
The conduit system can equally well for a fluid such as water, air
and washing or rinsing eye
be determined. Likewise, according to the invention is not excluded in
a household appliance
to provide multiple line systems, each with a node component,
wherein the respective conductive agents are the same or different from each other,
or multiple node components in a single piping system
the provision of a single, star-shaped conduit system
The advantage is that even only this single line system appropriate
Fasteners such as cable ducts,
Clamps and attachment points must be provided. Also, the
required lines kept optimally short, and parallel to
Lines are largely avoided. Thus, the invention leads to a
Significant reduction required for switching the home appliance
Development, material and assembly costs. The invention in total
resulting simplification of the line effort is also helpful
in avoiding susceptibility to interference

the invention to be provided
Nodal component as well as its structure and function are basically none
to make special demands; in a simple case
the node component merely a collection point for a plurality of
Lines, possibly supplemented
to a suitable fastening device. However, it may make sense
be the node component with certain, necessary for the operation of the household appliance
In a preferred embodiment of the domestic appliance according to the invention a plurality of lines are connected to the node component, wherein the functional components connected to these sub-lines are spatially close to each other, so closely adjacent so that they are much closer to each other than not connected to such kind NEN functional components are. In this case, the mutually tightly adjacent functional components are connected to the lines via an associated single connector with further preference, which further reduces the material and assembly costs.
a particularly preferred embodiment of the domestic appliance according to the invention contains the node component
a control device for
the other functional components. This gives an extra
Simplification, since in this way the control of other functional components, and
thus in particular the entire domestic appliance, from the center of the

is also the application of the invention in a household appliance, in which
the piping system is a union of electrical wiring.
Household appliance according to the invention is preferably
designed as a laundry treatment machine,
especially as a washing machine.
The invention will be explained below with reference to the drawing. The drawing

in the form of a washing machine, which components usual manner of a present

1 shows a view of the household appliance obliquely from the front; and
2 a view of the same household appliance diagonally from behind.
As both figures use the same household appliance 1 to the subject, reference is made below to both figures together. The household appliance 1 is a washing machine and contains a node component as a central component 2 , which in turn an electronic control device for the domestic appliance 1 and all its components needed to operate the power supply or control. Via signal lines 3 or power lines 4 is the node component 2 with other functional components 5 to 10 connected. These other functional components 5 to 10 put those for a washing machine 1 necessary functional components by no means exhaustive and are presented and listed in the present example only. The wires 3 and 4 are different depending on the requirement as signal lines 3 or power lines 4 depending on whether they are the transmission of signals or the transmission of energy, such as energy to operate a drive motor 5 or a pump motor 6 serve. In accordance with conventional practice, signal lines may be required 3 and power lines 4 to provide and relocate separately from each other, where appropriate, while maintaining sufficient physical distances or by applying additional screening measures; Reference is made in this respect to the knowledge and practice of specialists in the relevant technical field.
The present example given and illustrated other functional components 5 to 10 include a drive motor 5 , a pump motor 6 , several sensors 7 , an inlet valve assembly 8th , a lock 9 and a line filter 10 , All these other functional components 5 to 10 are known in their peculiarity and function in the relevant field. So serves the drive motor 5 for driving one in the tub 11 arranged, not shown here drum. The pump motor 6 serves for pumping out of washing liquor from the tub 11 , The sensors 7 Measure movements of the drum and the tub 11 , Especially when the drum is rotated very fast during a spin operation, or the filling state of the tub 11 with washing liquor. The inlet valve arrangement 8th is used to control the supply of fresh water to the tub 11 ; the closure 9 is from the node component 2 monitors, and operation of the household appliance 1 will only be allowed if the lock is closed; the line filter 10 is used to filter out faults which occur via the connection of the household appliance 1 could penetrate to a (not shown) power grid.
The important thing here is that all lines 3 or 4 the nodal component 2 each with a different functional component 5 to 10 connect directly, so that from all lines 3 and 4 formed line system star-shaped with the node component 2 is designed as a center. It is also noted that the other functional components 5 to 10 by no means arbitrary about the domestic appliance 1 but distributed in a corner of the household appliance 1 are concentrated - so far, for example in the case of the drive motor 5 and the pump motor 6 - There are no circumstances that require a different placement. That as many functional components 2 and 7 to 10 As close as possible, in conjunction with the star-shaped design of the line system results in an arrangement in which all lines 3 and 4 be interpreted as short as possible. This creates on the one hand Space in the household appliance 1 and, on the other hand, reduces the susceptibility of the conduit system to the interference infiltration. This results in a household appliance 1 , which can be mounted with little effort, which in terms of the material used for cables 3 and 4 requires a particularly low effort and in terms of reliability of the line system and all functional components 2 and 5 to 10 is particularly favorable.
