Description

Platform for a dishwasher

The invention relates to a dishwasher, comprising a trough with walls open to the front and the bottom and at least partially made of stainless metal, a separate housing, a mounting base at least partially made of plastic, wherein the trough is arranged on the mounting base to form a washing container and the Spülbehälterbodenwandung is formed by the mounting floor. The invention further relates to a production method for such a dishwasher.

The basic structural design of a dishwasher, in particular a domestic dishwasher, is referred to as a so-called platform. The platform of a dishwasher essentially comprises the washing container and the storage of the washing container on the floor, z. B. with a mounting base made of metal or plastic. Under certain circumstances, under the platform in addition to the above mentioned the installation or installation of functional components, such. As pumps, heating, electrical or hydraulic connectors, screens or water softening device, understood and / or the housing understood.

The following platform is known from the prior art: a rinsing container is placed on a mounting base made of plastic. The washing container with two side walls, a rear wall, a bottom wall and a top wall (only open to the front) is completely made of stainless steel and is produced by means of forming and joining methods, eg. B. welding, made of generally several stainless steel sheets. The assembly floor is therefore an upwardly open trough, which is shown for example in EP 0 243 632 A2 and EP 0 243 631 B1 of the applicant.

At the washing container made of stainless steel and / or on frame parts preferably metal, the housing (preferably designed as coated metal sheets) on the dishwasher usually fixed substantially point or with small contact surfaces, for example by screwing or clamping. The housing thus consists of at least one separate outer wall. The stainless steel rinsing container is thus a separate, independent component from the housing and not integrated in a housing, for example made of plastic, ie in particular has a large area. connected. The visible stainless steel surface in the washing container is therefore not a mere coating or lining of the housing, for example made of plastic, with stainless steel or a stainless steel sheet encapsulated in the injection molding of the plastic housing, as in EP 0 556 787 B2. Housing and washing containers are so far independent of each other. This structural design between housing and rinsing container also applies to DE 101 56 423 A1 of the Applicant and EP 0 452 287 B1 as prior art mentioned further below.

From EP 0 556 787 B2 a platform is known having an upper part comprising two side walls, a top wall and a rear wall, in which the housing and the part of the washing compartment formed by the top form a unit and are double-walled, d , H. are made of plastic and are mounted on a mounting base as a base, also made of plastic, which is therefore a different platform concept than described above, in particular because of the use of plastic and the integrated connection between the housing For the visual enhancement, for example, at least part of the visible surface of the bottom of the rinsing chamber, which is formed integrally with the plastic base, may have a metallic surface.

In further development of the platform first described above (not EP 0 556 787 B2), EP 0 452 287 B1 discloses a rinsing container which has only two side walls, a rear wall and a top wall made of stainless steel (trough) and the bottom wall of the rinsing container from the assembly floor is made of plastic, d. H. the assembly floor is thus not an upwardly open trough as in EP 0 243 632 A2 and EP 0 243 631 B1, but a box which is essentially closed on all sides.

From DE 101 56 423 A1 of the applicant is also a platform with a washing container of two side walls, a rear wall and a top wall made of stainless steel known. The bottom wall of the washing container is also formed by the mounting base made of plastic. This platform concept, in particular known from EP 0 452 287 B1 and DE 101 56 423 A1 of the applicant, in which the mounting base made of plastic forms the bottom wall of the washing container and have a separate housing, are cheaper to manufacture and simpler to manufacture. A disadvantage of these two last-mentioned platforms, however, is that inside the washing container, ie after installation of the dishwasher on the visible to the end user surface of the bottom wall of the washing plastic and stainless steel is not visible. The end user considers the use of stainless steel in the rinsing container as a special quality feature, so that this platform concept thus appears to be of lower quality for the end user or user of the dishwasher.

The object of the present invention is therefore to provide a dishwasher with a platform which on the one hand is inexpensive and easy to manufacture and on the other hand appears to the user of the dishwasher of high quality. The object is also to provide a method for producing such a dishwasher.

This object is achieved by an inventive dishwasher according to claim 1 and an inventive method for producing a dishwasher according to claim 29. Advantageous embodiments are the subject of the dependent claims.

The dishwasher according to the invention comprises a forward and bottom open and at least partially made of stainless metal trough with walls, a separate housing, a mounting base at least partially made of plastic, wherein the trough is arranged on the mounting base to form a Spülbehälters and a Spülbehälterbodenwandung from the mounting floor is formed, wherein the visible surface in the interior of the washing container of the Spülbodenbodenwand formed by the mounting base at least partially has a surface made of stainless metal, in particular stainless steel. As a result, the user the impression of a completely made of stainless steel rinse tank can be generated, which represents a special quality feature for the consumer. - A -

Preferably, the visible surface in the interior of the washing container of the Spülbehälterbodenwandung formed by the mounting base at least partially has a surface structure, for. As a honeycomb, circular, grooved or rectangular surface, on. This surface structure gives the user a special, high quality image of the dishwasher and can reduce noise, d. H. thus also develop a technical effect.

In a supplementary embodiment, the visible surface in the interior of the washing container of the Spülbehälterbodenwandung formed by the mounting base is at least partially made of a stainless metal foil, in particular noble metal foil, for. B. of chromium-nickel steel. A darartige metal foil is particularly inexpensive and lightweight and is connected by overmolding with the plastic of the mounting floor.

Advantageously, the visible surface in the interior of the washing container of the Spülbodenbodenwand formed by the mounting base is at least partially made of a stainless metal sheet, in particular stainless steel sheet, z. B. of chromium-nickel steel. Due to the relatively large thickness, the metal sheet has the advantage that it is very resistant to mechanical stresses.

Advantageously, the visible surface in the interior of the washing container of the Spülbehälterbodenwandung formed by the mounting base is at least partially from an insert as preferably preformed stainless metal sheet, in particular E- delstahlbelch, z. B. of chromium-nickel steel. An insert part may only need to be placed on the mounting floor, so that the installation costs are very low.

In a further embodiment, the insert is placed on the plastic Spülbehälterbodenwandung the mounting base without or with sealing against the plastic Spülbehälterbodenwandung the mounting base or spaced the insert, in particular forming a gap to the plastic Spülbehälterbodenwandung arranged, for example by means of spacers. In an additional embodiment, a closed Spülbehälterbodenwandung made of plastic is present. Thus, no sealing means between the einzubringen Zusatzeilen, z. As metal foil, sheet metal or insert, or layers and the Spülbehälterbodenwandung the mounting base required because the mounting floor itself, regardless of additional parts, is watertight due to lack of openings.

In a further embodiment, the visible surface in the interior of the washing container of the Spülbehälterbodenwandung formed by the mounting base is at least partially made of a stainless metal sheet or insert, in particular stainless steel, z. As chrome-nickel steel, formed, wherein the metal sheet is sealed against the plastic Spülbehälterbodenwandung, z. B. by a splice or area or by a gap-free bond between the metal sheet or insert, for example, prepared by injection molding.

Preferably, the insert is connected via at least one latching with the Spülbehälterbodenwandung made of plastic.

Conveniently, a Spülbehälterbodenwandung of plastic with at least one opening is present.

In a further embodiment, the mounting floor is statically self-supporting, d. H. statically independent of metal foil and / or metal sheet and / or insert on the Spülbehälterbodenwandung. Thus, the mounting floor can also be used for variants without additional parts.

In a supplementary embodiment, the arrangements of metal foil, metal sheet and / or insert and / or coatings on the Spülbehälterbodenwanung are combined. This allows a different surface to be produced on the surface of the Spülbehälterbodenwandung, leaving the user a marketing-relevant visual impression.

In a further embodiment, the trough made of stainless metal, in particular stainless steel, not a casing of a plastic housing. This is not a structural design of housing, washing container and mounting base before, which in the EP 0 556 787 B2. A separate housing is understood to mean an arrangement of housing, washing container and mounting floor, which does not correspond to an arrangement as in EP 0 556 787 B2.

Preferably, the housing is arranged separately or separately from the trough and / or mounting floor.

Conveniently, the separate housing is not a large area connected to the trough and / or mounting base, d. H. the housing is an independent component relative to the trough.

In a further embodiment, the housing is selectively or with small contact surfaces with fastening means, for example by screwing, riveting or jamming, connected to a frame and / or the washing and / or the mounting base.

In a further embodiment, the separate housing consists of at least one wall, for example of coated metal sheets, and preferably comprises two housing side walls and an upper housing wall.

In an additional embodiment, the walls are at a small distance, z. B. in the range of 0.1 to 7 cm, arranged by the walls of the trough and / or the walls of the mounting base.

Conveniently, the walls of the trough are a left rinse tank side wall, a right rinse tank side wall, a rinse tank rear wall, and a rinse tank top wall.

In a further embodiment, the trough made of stainless steel, such as chromium-nickel steel or stainless metal, for. B. chrome steel. An entirely stainless steel trough gives the consumer a particularly high quality impression. Chromium steel is cheaper than chromium-nickel steel in terms of material price, but has the disadvantage that long-term contact with water or moisture can cause corrosion. In the interior of a washing container is such a long-term con- However, water is not available, for example only behind gaskets. Chrome steel is therefore considered as stainless metal.

In a further embodiment, the mounting floor is designed as a shell structure with a Spülbehälterbodenwandung, a rear wall, two side walls, a bottom wall and a front wall.

In a further variation, the bottom wall of the mounting base is made of a material other than plastic, for. As metal, and is via connecting means, for. As a screw and / or clamp connection, attached to the remaining mounting base (16).

Preferably, the walls of the mounting floor openings for repair and maintenance purposes.

Conveniently, the mounting floor is designed as a frame structure.

In a further embodiment, the mounting floor is multi-part. The mounting floor can thus be composed of several parts, which may also consist of different materials.

In an advantageous embodiment, the plastic of the mounting floor is thermoplastic material, for. B. polypropylene (PP).

Conveniently, it is a household dishwasher, d. H. for example, not a commercial dishwasher.

Normally it is a built-in, solo or base dishwasher or a fully integrated dishwasher, but not a compact or table dishwasher. Built-in, solo or built-under dishwashers or fully integrated dishwashers (approximate dimensions: height 82 to 88 cm, width 60 cm or 45 cm, depth 57 cm or 50 cm) compared to so-called compact or tableware dishwashers (approximate dimensions, for example: height: 45 cm, width: 55 cm, depth: 46 cm) measurements. Solo dishwashers are understood to mean a freestanding dishwasher not intended for installation in a fitted kitchen.

In a method according to the invention for producing a dishwasher, comprising a trough with walls which is open at the front and at the bottom and made at least partly of rustproof metal, a separate housing, a mounting floor consisting at least partially of plastic, the trough being arranged on the mounting floor to form a Rinsing container and a Spülbehälterboden- wall is formed by the mounting base, is applied to the visible surface in the interior of the washing container formed by the mounting base Spülbehälterbodenwandung at least partially another material or added or added as the plastic of the rest of the mounting base.

Preferably, the other material is stainless metal, e.g. As chrome-nickel steel or chrome steel, and it is a metal foil, a metal sheet or an insert, which is connected by molding, gluing, laying or latching with the plastic of the mounting base.

In a supplementary embodiment, on the metal foil, the stainless metal sheet or the insert at least partially a surface structure, for. As a honeycomb, circular, grooved or rectangular surface, applied, for example by forming, for. B. deep drawing, bending or extrusion or machining production processes, for. As milling or grinding, or ablation, z. As thermal, chemical or electrochemical ablation, or laser cutting.

Conveniently, the other material is applied by coating on the Spülbehälterbodenwandung.

In a supplementary embodiment of the trough is inserted into a preferably groove-shaped receptacle on the mounting base and connected by fastening methods, such as screwing, gluing or clamping, with the mounting base.

In a further embodiment, a dishwashing machine according to the invention having the features described above can be produced with the above method. Stainless steel is understood to mean a metal which, on being in constant contact with water or moisture, has a corrosion formation but does not exhibit any corrosion in the case of non-continuous contact with water or moisture. For example, chromium-nickel steel as stainless steel has no corrosion even with constant contact with moisture or water. For example, chromium steel as a stainless metal, which is cheaper than chromium-nickel steel, has corrosion when constantly in contact with water or moisture, but in non-continuous contact with water or moisture no corrosion. For example, in columns or behind seals that constantly contain moisture or water, occurs in a trough made of chrome steel therefore corrosion. Inside a rinsing container, there is no constant contact with water or moisture, so that a rinsing tank made of chromium steel has no corrosion inside. Stainless steel is a subset of the stainless metals, so stainless steel is also understood to mean stainless steel.

The invention will be explained by way of example with reference to drawings. Show it:

FIG. 1 shows a perspective view of a dishwasher 1 according to the invention. The dishwasher 1 has a pivotable about a horizontal axis door 15 for opening and closing the washing container 14 with an upper and lower dish rack 10 for receiving items to be washed, z. B. Household utensils. The lower dish basket moves on rollers on a correspondingly molded runway 12. The door 15 is constructed of an inner door 5 made of a molded stainless steel sheet and an outer door 2 arranged at a distance from the inner door 5 as an outer casing or housing. On the outside door, for example, an additional panel for adaptation to the kitchen equipment can be applied to a built-in or under-counter dishwasher. At the upper part of the outer door 2 is a control panel 4 for operating the dishwasher. 1 For the outer lining of the dishwasher 1, a left housing side wall 6, a right housing side wall 7 and an upper housing wall 9 are arranged around the washing container 14 and the assembly bottom 16 (not shown) arranged below the washing container 14. Between the walls 1 1, 17, 18 (partially not shown) of the washing compartment 14 and the housing walls 6, 7, 9, for example made of coated sheet metal parts, there is a small distance, for. B. in the range of 0.1 to 12 cm. Between the housing walls 6, 7, 9 and the walls 1 1, 17, 18 (partially not shown) of the washing compartment 14, a single or multi-part front panel 8 is attached to the opening of the washing compartment 14. The housing walls 6, 7, 9 are on the washing container 14 or trough 40 and / or supporting frame parts, in particular made of metal (not shown). via fasteners, e.g. As screws attached. There is thus a separate housing from the washing container 14, ie the walls of the washing container 14 are not a large area in combination with the housing and the housing side walls 6, 7, 9 have a small distance from the washing container 14th

A portion of the washing container 14 as a forward and downwardly open trough 40 is from a left Spülbehälterwand 1 1, a right Spülbehälterwandung 18 (not shown), a Spülbehälterrückwandung 19 (not shown), a Spülbehälterdeckwandung 17 (not shown) in each case by joining method, z. B. welding, interconnected stainless steel sheets formed (see Fig. 2). The Spülbehälterbodenwandung 3 is part of the mounting base (not shown). In order to obtain a metallic appearance, in particular a stainless steel surface, in the bottom area of the washing compartment 14, an insert part made of stainless metal or a stainless steel insert part, e.g. B. formed by deep drawing stainless steel sheet, molded. The options available for this purpose are explained below by way of example.

FIG. 2 shows a perspective view of a platform 25 (mounting floor 16 and trough 40 of the washing container 14) of a dishwasher 1 according to the invention. The bottom wall 3 of the washing container 14 is formed by the mounting base 16 made of plastic. The mounting base 16 is preferably made by injection molding of a thermoplastic material, for. As polypropylene (PP), produced inexpensively. The left Spülbe- container side wall 1 1, the right Spülbehälterseitenwandung 18, the Spülbehälterdeckwandung 17 and the Spülbehälterrückwandung 19 are made of stainless metal, eg. As chrome steel or stainless steel, z. B. chromium-nickel steel, but also at least one wall 1 1, 17, 18, 19 of the trough 40 may be made of a different material than stainless steel, for example, the Spülbehälterdeckwandung 17 made of plastic. It is z. B. formed stainless steel sheets, which by joining process, for. B. welding, have been joined together. At the upper edge of the mounting base 16, a groove-shaped receptacle 20 is formed, in which the walls 1 1, 18, 19 are used for connection, for example by screwing, gluing or clamping means with the mounting base 16. There may also be other types of connection, eg. B. without groove-like recording, running. On the outside of the walls 1 1, 17, 18, 19 stainless steel of the forward and downwardly open trough 40 is preferably a soundproofing, z. As bitumen, applied.

The mounting floor 16 has an upper wall 3, which forms the Spülbehälterboden 3, a rear wall 24, two side walls 23, a bottom wall 22 and a front wall (not shown). In the Spülbehälterbodenwandung 3 a drain sump 21 is formed. The walls 22, 23, 24 of the mounting base 16 can also smaller and larger openings, for. B. for repair or maintenance purposes, have. For larger openings, the mounting floor 16 may also have more of a frame structure than a shell structure. In the mounting base 16 are preferably receiving and fastening means for functional components, eg. As pumps, heating, electrical or hydraulic connectors, screens or water softening device, available (not shown). The mounting base 16 may also be composed of various items that may also be made of a different material than plastic, z. As metal, exist. The bottom wall 22 could z. B. be formed as a sheet metal part, which by connecting means, for. B. a screw and / or clamp connection, is attached to the remaining mounting base 16 (not shown).

The visible in the interior of the washing container 14 surface of the Spülbehälterbodenwandung 3 has at least partially a different appearance than the rest of existing plastic mounting base 16 or made of plastic part of the mounting base 16, which is gray, for example. Preferably, the other appearance corresponds to the appearance of the walls 1 1, 17, 18, 19 made of stainless steel. In addition, another surface structure of the visible surface of the Spülbehälterbodenwandung 3 with respect to the walls 1 1, 17, 18, 19 are selected from stainless steel, for example, a honeycomb-like, circular (stringing circles), grooved or rectangular surface. Furthermore, a different color can be selected, as the walls 1 1, 17, 18, 19 made of stainless steel and the mounting base 16 have, z. B. in green or yellow. Thus, the user of the dishwasher can be given the impression of a particularly high quality rinsing container 14.

In the following FIGS. 3 to 10, various embodiments for producing the different appearance of the surface of the washing compartment bottom wall 3 are shown. Basically, a variant of a closed assembly floor is used. dens 16 in Figs. 3 to 7 and an open mounting base 16 in Figs. 8 to 10 distinguished. In the variant of the closed mounting base 16, the Spülbehäl- terbodenwandung 3 plastic of the mounting base 16 no openings 26, ie, is closed as shown in Fig. 2. In contrast, there is the variant of the open mounting floor 16, which has openings 26 in the Spülbehälterbodenwandung 3 made of plastic of the mounting base 16.

In Fig. 3 is a longitudinal section through an upper wall 3 of a mounting floor 16 is shown as a closed variant. In the Spülbehälterbodenwandung 3 is a stainless metal foil 27, in particular stainless steel metal foil 27, z. As chromium-nickel steel, introduced. For this purpose, the metal foil 27 is introduced during the injection molding of the mounting base 16 made of thermoplastic material prior to the introduction of the molten and homogenized plastic in the tool and thereby the metal foil 27 connected by back molding with the mounting base 16. The metal foil 27 can also over a larger or the entire region of the visible part of the Spülbehälterbodenwandung 3, z. B. to the runway 12, be arranged (not shown). In the longitudinal section in Fig. 3 is still the drain sump 21, the runway 12 for the lower dish rack 10 (not shown) and the outer groove wall 28 and the inner groove wall 29 for the groove-shaped receptacle 20 recognizable.

In the following FIGS. 4 to 10, for simplification reasons, only the right-hand part of the washing compartment bottom wall 3 is shown analogously to FIG.

FIG. 4 shows a longitudinal section through one half of an upper wall 3 of a mounting floor 16 as a closed variant in a further embodiment. A preformed stainless metal sheet 30, in particular Edelstahlbech, z. B. chrome-nickel steel, is introduced into the Spülbehälterbodenwandung 3. The metal sheet 30 is introduced for this purpose before injection molding in the tool and then back-injected with plastic. This results in a liquid-tight bond between the metal sheet 30 and the remaining plastic part of the Spülbehälterbodenwandung 3 of the mounting base 16. The left end in Fig. 4 corresponds to the region 31 of the drain sump 21st In Fig. 5 is a longitudinal section through one half of an upper wall 3 of a mounting floor 16 as a closed variant in a further embodiment with an insert 32 as a preformed stainless metal sheet 32, in particular stainless steel sheet 32, z. B. made of chrome-nickel steel. The insert 32 is not back-injected, but placed on the surface of the Spülbehälterbodenwandung 3 made of plastic. Under certain circumstances, a preferably punctual fixation of the insert 32 at the Spülbehälterbodenwandung 3. This is no liquid-tight connection between the insert 32 and the Spülbehälterbodenwandung 3, so that wash liquor, for example at the penetration point 33 between the insert 32 and the surface of the plastic part of the Spülbehälterbodenwandung. 3 can penetrate. Penetrated rinsing liquor can, however, flow off at the exit point 34 into the drain sump 21, ie in the region 31 of the drain sump 21. Due to the closed variant of the mounting base 16 of the washing compartment 14 is thus still liquid-tight.

In Fig. 6 is a longitudinal section through one half of an upper wall 3 of a mounting floor 16 as a closed variant in another embodiment with a sealed insert 32 as a preformed stainless metal sheet 32, in particular Edelstahlbech 32, z. B. made of chrome-nickel steel. The insert 32 is placed on the surface of the Spülbehälterbodenwandung 3 analogously to the embodiment shown in FIG. However, there are sealing elements 35 between the insert 32 and the surface of the plastic part of the Spülbehälterbodenwandung 3 available, so that no rinse liquor between the insert and the surface of the Spülbehälterbodenwandung 3 can penetrate. The sealing element 35 in the region 31 of the drain sump 21 is optional.

In Fig. 7 is a longitudinal section through one half of an upper wall 3 of a mounting floor 16 as a closed variant in a further embodiment with a spaced insert 32 as a preformed stainless metal sheet 32, in particular Edelstahlbech 32, z. B. made of chrome-nickel steel. With the help of spacers 36, z. B. in the form of imprints on the underside of the insert 32 or at the top of the Spülbehälterbodenwandung 3, a gap 37 between the insert 32 and the top of the plastic part of the Spülbehälterbodenwandung 3 is generated. As a result, rinsing fluid can penetrate into the gap 37 at the point of penetration and drain at the exit point 34 into the drain sump 21. In FIGS. 8 to 10, the open variant of the mounting floor 16 is shown. In this variant of the mounting base 16, an opening 26 in the plastic part of the Spülbehälterbo- wall 3 is present, which is why the junction between insert 32 and mounting base 16 must be liquid-tight. The insert 32 may, but need not, provide a contribution to the static stability of the plastic mounting floor 16.

In Fig. 8 is a longitudinal section through one half of an upper wall 3 of the mounting base 16 is shown as an open variant. The insert 32 as a preformed stainless metal sheet 32, in particular Edelstahlbech 32, z. B. chromium-nickel steel, is inserted into the mold during injection molding of the mounting base 16 made of plastic and molded. This creates a liquid-tight connection between the insert 32 and the mounting base 16th

In Fig. 9 is a longitudinal section through one half of an upper wall 3 of the mounting base 16 is shown as an open variant. The insert 32 as a preformed stainless metal sheet 32, in particular Edelstahlbech 32, z. B. made of chrome-nickel steel, is fixed by means of splices 39 on the mounting base 16 and at the same time the required liquid tightness between the insert 32 and the surface of the plastic part of the Spülbehälterbodenwandung 3 produced.

FIG. 10 shows a longitudinal section through one half of an upper wall 3 of a mounting floor 16 as an open variant. The insert 32 as a preformed stainless metal sheet 32, in particular Edelstahlbech 32, z. B. chromium-nickel steel, is fixed by means of at least one latching 38 on the mounting base 16. The latching 38 can also be arranged at other locations than shown in FIG. 10 (not shown). The sealing element 35 ensures the required tightness between the insert 32 and the plastic part of the Spülbehälterbodenwandung. 3

In this embodiment, as well as in all other embodiments or variants described above, instead of an insert 32 made of metal and an insert 32 can be inserted from plastic. As a result, a rinsing container bottom 3 with a visible metal surface, in particular a stainless steel surface, and a plastic surface can also be produced with the same mold for injection molding of the mounting base 16 become. This thus makes possible a platform concept which is suitable both for low price classes with visible plastic in the bottom area of the washing compartment 14 and for higher price classes with a preferably visible stainless steel surface in the bottom area of the washing compartment 14. Furthermore, the insert part 32 made of plastic can also be produced in other colors as well as with a certain surface structure and thus the surface of the washing container 14 in the bottom region can be optically diversified. Also, the inserts 32 preferably made of stainless steel may have a surface of the structure of the walls 1 1, 17, 18, 19 different surface texture, for. B. a honeycomb-like, circular (sequence of circles), grooved or rectangular surface. This allows the interior of the washing further diversify for different price ranges, z. B. also for upper class dishwashers.

In addition to the possibilities shown in the above embodiments in FIGS. 1 to 10, all other technical applications for producing a different appearance of the wall 3 of the mounting base 16 can be used. For this purpose, for example, comes the coating, d. H. the application of a firmly adhering layer of any formless material on the wall 3 of the assembly floor 16 (eg sputtering, chemical processes, painting, painting, eg painting, spraying, dipping etc.).

Overall, a variable platform concept is provided with the present inventive dishwasher, which allows the advantages in the manufacturing process of a prior art platform concept in which the mounting base made of plastic forms the bottom wall of the washing and a separate housing is present with the aesthetic and thus to combine marketing-relevant advantages of a completely made of stainless steel washing container. In addition, the visible surface of the bottom wall of the washing container can be further diversified, so that even greater flexibility for adaptation to different price categories of dishwashers is possible.
