- the fastening device 29 either lies loosely on the second insulation element 25 or is connected to it in such a way that the
- Isolation element 25 can be solved.
- a non-releasable connection can also be provided between the second insulation element 25 and the fastening device 29.
- the second insulation element 25 can be made from a self-adhesive bitumen.
- Such a permanent connection is particularly advantageous on the door 3.
- a separating layer 32 can be provided between the second insulation element 25 and the fastening device 29.
- the separation layer 32 is optional.
- the separating layer 32 can be constructed identically to the separating layer 28.
- the fastening device 29 can on the rear wall 9
- Isolation arrangement 15 are held in position on the washing compartment 2.
- 2B shows a schematic partial sectional view of a further embodiment of the rinsing container 2 in an exploded view.
- 3B shows another
- Partial sectional view of the washing container 2 differs from the washing container 2 according to FIGS. 2A and 3A only in that the insulation arrangement 15 has only the first insulation element 20. In particular, the second insulation element 25 is not provided.
- FIG. 4 shows a schematic sectional view of a further embodiment of a household dishwasher 1.
- the fastening device 29 can be designed as an outer lining attached to the side wall 10.
- the fastening device 29 can be connected to the ceiling 8 and the floor 7 and press the insulation arrangement 15 adhering to the side wall 10 with a defined contact pressure P against the side wall 10.
- the fastening device 29 can be spring-biased.
- FIG. 5 shows a schematic sectional view of a further embodiment of a household dishwasher 1.
- the fastening device 29 is designed such that it does not rest flat on the insulation arrangement 15, but only in a punctiform and / or linear form on the latter.
- the fastening device 29 can thus have any geometry.
- FIG. 6 shows a schematic sectional view of a further embodiment of a household dishwasher 1.
- the fastening device 29 is designed as a network or grid.
- the fastening device 29 can be a plastic mesh or a plastic mesh or a metal mesh or a metal mesh.
- Fastening device 29 can in turn be connected to the ceiling 8 and the floor 7 in order to press the insulation arrangement 15 against the side wall 10 with the contact pressure P.
- FIG. 7 shows a schematic sectional view of a further embodiment of a household dishwasher 1.
- Household dishwasher is the insulation assembly 15 on the floor 7 arranged and fastened to the floor 7 with the aid of a fastening device 29 as explained above.
- the contact pressure P can be determined by the geometric configuration of the fastening device 29 and adapted to the choice of material.
- Fastening device 29 can ensure the bond between the insulation arrangement 15 and the washing container 2 over the entire service life of the domestic dishwasher 1.
- the use of grids or nets made of plastics or metals for the fastening device 29 enables the insulation arrangement 15 to be fixed over a large area with little material expenditure.
- the thermal and / or acoustic function of the insulation arrangement 15 is constant
- FIG. 8 shows a schematic sectional view of a further embodiment of a household dishwasher 1.
- the household dishwasher 1 is cut parallel to the side walls 10, 11 so that in FIG. 8 the door 3 and the
- Rear wall 9 can be seen in section.
- an additional mechanical fastening is particularly advantageous. This can be integrated into the external second insulation element 25.
- the fastening device 29 is curved in an arc shape, so that the insulation arrangement 15 can be pressed against the rear wall 9 with a spring preload.
- a stiffening 33 in the form of ribs or a corrugation can additionally be provided.
- this stiffening 33 can be an additional external component.
- the second insulation element 25 can be designed in such a way that it is geometrical and / or of the
- Material properties forth provides sufficient rigidity to be pressed against the rear wall 9 of the washing compartment 2 over the entire width.
- Insulation element 25 to be formed inwards, in the direction of the washing compartment 2.
- the fastening device 29 can be fastened to the rear wall 9 of the washing compartment 2, if only on the edge of the
- Isolation arrangement 15 a bracket or attachment is provided.
- the stiffening 33 then acts across the width of the insulation arrangement 15 and transfers the holding forces into the insulation arrangement 15. In this way, an increase in the bending stiffness of the insulation arrangement 15 for the rear wall 9 can be achieved.
- the insulation arrangement 15 can be biased inwards in the direction of the washing compartment 2, and fixing is only required at the edge and leads to a secure, permanent and full-surface fixing of the insulation arrangement 15 on the rear wall 9.
- the stiffening 33 results in an acoustically favorable connection of the rear wall 9 to the first insulation element 20.
- a permanent and secure connection of the insulation arrangement 15 to the rear wall 9 is achieved.
- a space-saving arrangement results when the stiffening 33 is shaped in the direction of the washing compartment 2.
