Abstract

The dishwasher has an additional support element provided at a bottom tub unit (7) of a rinsing container or at a base carrier unit (5), which is arranged below the tub unit. The support element holds a ballast weight (25). The support element is integrally integrated at the tub unit and/or the carrier unit in a plastic injection molding process. The carrier unit defines a mounting chamber, in which device components and/or safety devices of the dishwasher are arranged. A storage chamber (31) for the ballast weight is separated from an assembly chamber by separation wall elements (27, 29). An independent claim is also included for a method for mounting a dishwasher.

Description

The invention relates to a dishwasher according to the preamble of claim 1 and a method for producing a dishwasher according to claim 15.

One, in particular a free-standing, dishwashers may each have one or more ballast weights to increase their stability, which serve as a counterweight against tilting of the dishwasher, for example when opening the door. The respective ballast weight is usually positioned as a concrete weight in the bottom area of the dishwasher. For example, in a rear opening in the substructure below the washing container of the dishwasher DE 600 36 242 T2 a ballast of raw concrete inserted and supported by the substructure. The ballast mass is held in position by the return of at least one of the side walls of the dishwasher. The concrete ballast mass is secured to the substructure by at least one screw passing through the ballast mass. Such assembly is often too cumbersome and / or too expensive in practice for the assembly of dishwashers in mass production. In addition, there may be problems with the sensitive overflow safety system in the substructure and / or the electronics housed there as particles separate from the raw concrete.

The object of the invention is to provide a dishwasher and a method for producing a dishwasher, in which the ballast weight can be fixed in a simple and cost-effective manner and reliably in the dishwasher.

The object is solved by the features of claim 1 or claim 15. Preferred embodiments of the invention are disclosed in the subclaims.

According to the characterizing part of patent claim 1, at least one additional support element for holding the ballast weight is provided on the rinsing container, in particular on its base pan unit and / or on a base unit arranged underneath, this carrying base support unit. The rinsing container, in particular its base pan unit, and / or the base support unit which is seated under the floor pan unit thus has at least one additional support element for holding the ballast weight. The ballast weight can therefore be attached directly to the bottom of the Bodenwannenheit and / or on the upper part of the base support unit with height clearance or height clearance to underlying device components or safety devices, whereby an otherwise free space can be used directly on the outer wall of the bottom pan unit or the Spülbehälters.

The support element may be integrally formed, in particular integrated, to reduce the component expenditure in the same material and / or in one piece, in particular in the plastic injection molding process, on the rinsing container or on the rinsing container bottom tray unit and / or on the base carrier unit. In this way, the underside of the washbasin tray unit may directly be an upper boundary surface which defines a storage space for the ballast weight upwards.

The rinsing container can be supported with its bottom pan unit on the base support unit. In particular, the floor pan unit of the base support unit, preferably from the outside, at least partially enclosed, and form the top wall. Here, the Bodenwanneneinehit can be made in one piece with the bottom-side base support unit as a plastic molded part. Alternatively, the Bodenwanneneeinheit or the entire washing can be kept as a separate from the base support unit component. In both cases, the washing container is supported with its bottom wall on the base support unit. For this case, the bottom pan unit of the washing container - regardless of the base support unit - are equipped with equipment components and / or with the ballast weight. Only after placement can then be connected to the underlying base support unit in a subsequent connection step, the washing container bottom pan unit.

The base carrier unit may have a substantially closed bottom plate framed by front, side and rear walls. Device components and / or safety devices of the dishwasher can be arranged in the mounting space thus formed. In the pre-assembly step, the mounting space of the base support unit can be designed to be open at the top, while in an assembled dishwasher the mounting space is limited on top by the bottom pan unit.

In order to ensure perfect functioning of the device components / safety devices arranged in the mounting space, no dirt particles from the ballast weight may enter the mounting space. Against this background, the support element may have a correspondingly sealed storage space for the ballast weight. This can be separated by a partition wall pollution-proof from the mounting space.

The dividing wall forming the additional supporting element can carry the ballast weight in addition to its separating function. For this purpose, the partition in the profile can be angularly formed with a wall section projecting downwards from the floor pan unit and a supporting section adjoining it, in particular projecting substantially horizontally. The ballast weight can rest on the support section in this case. In particular, the additional support element may have an approximately L-shaped profile cross-section. This advantageous construction allows in particular a substantially horizontal insertion of the ballast weight or ballast unit.

Additionally or independently thereof, it may also be expedient if the partition wall element is configured as a wall-shaped, in particular L-angular, wall part with a wall section projecting upwards from the base support unit and a supporting section adjoining it, in particular substantially horizontal , This advantageous construction allows in particular a substantially horizontal insertion of the ballast weight or ballast unit.

The storage space of the support element may be in the pre-assembly state, that is, in the bottom tray unit detached from the base support unit, in particular open from the outside freely accessible, insertion area to ensure easy insertion of the ballast weight. For a largely pollution-proof arrangement of the ballast weight, the support element can cooperate with at least one closing wall. This may optionally be adjustable relative to the support element. In the closed position of the closing wall, the ballast weight can be substantially dirt-tight, in particular dust-tight, arranged in the storage space. In contrast, in the open position of the closing wall, the support element can be equipped with the ballast weight.

In one embodiment, the closing wall may be formed on the base support unit or on the floor pan unit, for example as a pivotable flap, which closes the insertion region of the support element on the base support unit after assembly of the flushing container, in particular the floor pan unit. Alternatively, the closing wall may be provided as a separate component which can be inserted into the insertion region of the support element in order to close it.

In contrast to the previous embodiments, the closing wall is formed in a simple embodiment fixed to the bottom support unit or integrated in the base support. After installation of the washing container, in particular the bottom pan unit on the base support unit, the closing wall can be brought to the support element in such a way that its insertion region is closed.

Preferably, the support element is formed on the back of the bottom pan unit. The storage space limited by the support element can be designed to be open on the rear side and / or in the device side direction, in particular in case of the base support unit dissolved bottom tray unit, to ensure easy insertion of the ballast weight.

Corresponding to the above-described position of the support element can act as a closing wall, the rear wall and / or the side wall of the base support unit. When mounted bottom tray unit therefore on the one hand, the rear wall and on the other hand in the device side direction, the opposite side walls of the base support unit can limit the storage space of the floor pan side support element largely pollution-tight.

For a permanently reliable holding the ballast weight, the support element, in particular its support portion, expediently dimensioned according to dimensionally stable. Thus, if necessary can be dispensed with costly stabilization measures on the support section, in an advantageous embodiment, the support member can be supported with its support portion on a support member of the base support, in particular on an upper side of a known recess or projection in the base support.

In addition, the support member may additionally stiffen the bottom assembly consisting of floor pan unit and base support unit, for example in the device side direction. For this purpose, the support element may expediently be designed so that it bridges opposite side walls of the base support unit. The support element can thus provide an additional force path. External clamping forces, such as those applied during the transport or storage of dishwashers, can thus be absorbed by the support element.

Other advantageous developments of the invention are given in the dependent claims.

The invention and its developments and their advantages will be explained in more detail with reference to drawings.

Elements with the same function and mode of action are in the FIGS. 1 4 each provided with the same reference numerals.

In the Fig. 1 is simplified in a perspective view of a dishwasher 1000 indicated, the bottom assembly is highlighted. The outer contour line of the washing container 100 of the dishwasher 1000 is indicated by a dashed line. Furthermore, a door 1 of the dishwasher 1000 is articulated in a known manner on lateral, plate-shaped hinge supports 3. The lateral hinge supports 3 are approximately angularly formed sheet-metal parts, which are held with their vertical legs laterally in a base-side base support unit 5 of the base assembly.

The in the Fig. 1 shown bottom assembly consists in addition to the base support unit 5 from a sitting above this bottom tray unit 7 of the washing container 100 of the dishwasher 1000. The bottom tray unit 7 and the base support unit 5 are manufactured as separate plastic injection molded parts, the front (, ie close to the door area) connection areas 11 and rear (, ie away from the door ) Connection areas 9 are connected to each other. By way of example, the base carrier unit 5 and the bottom pan unit 7 are latched to one another at their rear connection regions 9.

The bottom pan unit 7 placed from above on the base support unit 5 is braced against the front and rear connection areas 11, 9 on the hinge supports 3 and on the rear mounting slots 13 of the base support unit 5. Between the tray unit 7 and the base support unit 5 there is a mounting space 15, in which device components, not shown here, as well as safety devices of the dishwasher are arranged, such as a float switch, which can detect leaking rinsing liquid.

In the Fig. 2 and 3 For example, the base support unit 5 and the floor pan unit 7 are shown in a pre-assembly state in which both parts are detached from each other. Here in the embodiment according to the Fig. 2 the base support unit 5 seated at the respective installation site has a substantially closed base plate 17, which is framed on the outer periphery by front, side and rear walls 18, 19, 20. The two rear mounting shafts 13 are each integrated directly in the side walls 19 and arranged in the corner regions between the side walls 19 and the rear wall 20. The rear wall 20 has a recess 21 which extends in the device side direction or width direction x over the entire width of the rear wall 20.

The in the Fig. 3 shown bottom pan unit 7 has an additional support member 23 for a ballast weight or a ballast unit 25. The support member 23 is formed as an angle section with a vertical wall portion 27 which protrudes downward from the bottom of the bottom pan unit 7 and merges into a horizontal support portion 29. It is considered in profile cross-section in particular L-shaped. The angle profile extends according to the Fig. 3 in the rear region of the bottom pan unit 7 in the device side direction x over a width b. The width b and the distance a of the two mounting shafts 13 is dimensioned such that in the assembled state, the support member 23, the two mounting shafts 13 bridged. When applying lateral, external clamping forces, therefore, the support member 23 additionally stiffen the bottom assembly.

According to the Fig. 3 and 4 The underside of the bottom pan unit 7, together with the vertical wall section 27 and the horizontal support section 29, defines a storage space 31 which has a laterally and rearwardly open insertion area for the ballast weight 25. Im, in the Fig. 3 shown pre-assembly state is therefore the ballast weight 25 readily in the storage space 31, in particular substantially in the horizontal direction in the plane defined by the width direction x and the depth direction y plane inserted.

When assembling the floor pan unit 7 with the base support or the base support unit 5, the angle profile 23 moves into the region between the two mounting slots 13 of the base support 5 that are integrated in the side walls 19. The mutually facing inner surfaces of the mounting shafts 13 can thus come into contact with the side edges of the wall sections 27, 29, which close the storage space 31 as a closing walls largely pollution-tight.

The assembly state is in the Fig. 4 shown. Accordingly, the horizontal support portion 29 of the angle section 23 rests with its rear free end on an upper side 33 of the recess 21 formed in the base support rear wall 20. Above the recess 21, the rear wall 20 projects beyond the back of the ballast weight 25 at a short distance. The rear wall 20 is while tangentially brought up to an outer curvature of the bottom tray 7.

The in the pre-assembled state laterally and rearwardly open storage space 31 is therefore after successful assembly according to Fig. 4 laterally sealed by the mounting shafts 13 and back by the base support rear wall 20 pollution-tight to the outside. The contact surfaces 35 between the support portion 29 and the top 33 of the recess 21 thereby form a sealing zone, which largely prevent a transfer of dirt particles into the mounting space 15. In addition, the base support rear wall 20 closes off the storage space 31 to the rear, so that the ballast weight is securely fixed during transport and the ballast weight 25 is arranged protected from the outside.

In this way, an encapsulated storage space 31 is provided for receiving a concrete block in the near-surface area of the dishwasher, which is at a height distance, i. with clearance distance HD above the bottom 17 of the base support unit 5 is located. As a result, dirt or dust particles detaching from the concrete block can not get into the mounting space 15, so that the functionality of device components or safety devices, such as a float switch, can be ensured within the dishwasher over its service life. Costly additional measures such. the sheathing of the concrete block with a plastic sheath can thus be omitted.

Additionally or alternatively to the present embodiment according to the FIGS. 1 with 4, it may also be appropriate if at least one additional support member for supporting the ballast weight is provided at a below the bottom tray unit, this carrying base support unit, at least. The above to the FIGS. 1 with 4 explained, constructive and functional measures apply to this modification in an analogous manner.

In this way, in summary, a low cost fixation capability for a concrete weight with clearance above the floor of the base support unit is provided so that the underlying mounting space may be occupied by other components, such as e.g. the circulating pump, drain pump, water separator, etc ... the dishwasher can be used.

In particular, a kind of drawer is formed in the bottom region of the washing container or inner container of the dishwasher by the additional, projecting support element on the bottom pan unit and / or the base support unit. It is designed so that a ballast weight can be inserted. Then, when this washing container with the tray unit is mounted on the base support unit, the rear wall of the base support unit (floor member) preferably closes this drawer and the weight is fixed, closed and protected on all sides.

• das Ballastgewicht kann als kostengünstiges Betongewicht ohne Kunststoffummantelung
  gestaltet werden;
• das Ballastgewicht ist von außen für den Kunden nicht sichtbar;
• das Ballastgewicht kann während des Transports der Geschirrspülmaschine nicht zerstört werden; ein etwaiger Schaden ist für Kunden nicht ersichtlich und führt daher zu einer geringeren Beanstandungsrate;
• die Schublade bzw. das zusätzliche Tragelement kann zusätzlich Klammerkräfte aufnehmen und dient daher zur weiteren Versteifung des Bodenbereiches der Bodenbaugruppe.

Advantages of this advantageous construction are in particular:

• the ballast weight can be as inexpensive concrete weight without plastic coating
  be designed;
• the ballast weight is not visible to the customer from the outside;
• the ballast weight can not be destroyed during the transport of the dishwasher; any damage is not apparent to customers and therefore leads to a lower complaint rate;
• the drawer or the additional support element can additionally absorb clamping forces and therefore serves to further stiffen the bottom region of the floor assembly.
