Description

The invention relates to a dishwasher with a guidance system for at least one, in particular Schübladenartig, out of a housing part of the dishwasher herausfahrbares container.

• wenigstens einem Paar an Gehäusewandungen gegenüberliegend angeordneter Schienen, die in voneinander beabstandeten ersten Laufrollen parallel zueinander geführt sind, und
• wenigstens einem Paar am Behältnis gegenüberliegend angeordneter zweiter Laufrollen, die in den Schienen geführt sind. Dabei sind jeder Schiene zwei Paar außen angreifende erste Laufrollen und zwei innen geführte zweite Laufrollen zugeordnet. Der Auszugsweg teilt sich auf in einen ersten Abschnitt, den die Schiene in bezug auf das Gehäuse des Geschirrspülers zurücklegt, und einen zweiten Abschnitt, den der Geschirrkorb in bezug auf die Schienen zurücklegt. Das Spiel beider Abschnitte führt zu Instabilitäten.

In order to be able to pull out, for example, baskets completely from the washing compartment of a dishwasher, guide systems are known with

• at least one pair of housing walls of oppositely arranged rails, which are guided in mutually spaced first rollers parallel to each other, and
• at least one pair on the container opposite arranged second rollers, which are guided in the rails. In this case, each rail is associated with two pairs of outer rollers acting on the outside and two inner rollers guided on the inside. The pull-out path is divided into a first section traversed by the rail relative to the housing of the dishwasher, and a second section covered by the dish rack with respect to the rails. The play of both sections leads to instabilities.

In order to reduce the game in the area of full extension rails in such dishwashers, was in the DE-A-199 59 754 proposed to guide the crockery basket in guide rails, which are wound along their guide path. Although it can be reduced by the thus caused tension of guided in the guide rails Träger_das game, this leads to the same side to a stiffness of the dish rack and increased wear.

From the US-A-4,226,490 For example, a dishwasher is known in which the upper crockery basket is supported in the region of its trailing edge with rollers against the upper side of the dishwasher so as to provide for vertical stabilization of the crockery basket.

Furthermore, from the DE-A-23 66 026 a device for guiding drawers known, in which in a drawer receiving furniture box resilient stops are mounted, which engage with attached to the drawer laterally projecting pin engage the drawer in the fully retracted and fully extended state in the extension direction of the drawer to lock.

In the US-A-4,199,377 is explained a furniture drawer system in which the side of the drawer guide rails are mounted, which are supported on mounted on the furniture box guide rollers. At the front of the drawer facing the end of the guide rails are bent out laterally from the guide rail tabs, which create the complete retraction of the drawer in the furniture box laterally against the guide rollers to center the drawer in the closed state with respect to the furniture box and lock.

In the DE-A 2 255 036 Further, a drawer is disclosed with a pull-out limit, which is formed by a roller which is attached to a permanently mounted in a furniture box guide rail and which applies against two above and below the guide rail attached to the drawer roles when the drawer is fully extended ,

The invention has for its object to provide a dishwasher with an improved guide system for particular drawer-like, herausfahrbares from a housing part of a dishwasher container in which the guiding stability is improved.

According to the invention, this object is solved by the features of claim 1. Advantageous developments emerge from the subclaims.

• wenigstens ein Paar Schienen, die an gegenüberliegenden Gehäusewandungen parallel zueinander geführt sind, und
• wenigstens einen ersten Stabilisierungskörper, der an wenigstens einer der Schienen auf der gehausezugewandten Seite angeordnet ist, um an wenigstens einer vorbestimmten Stabilisierungsposition für den ausgefahrenen Zustand der Schiene mit wenigstens einem raumfesten zweiten Stabilisierungskörper, der schienenzugewandt montiert ist, eine spielbehaftete Passung oder eine federnde Anlage zu bilden.

The guide system for a, in particular drawer-like, herausfahrbares container of a dishwasher has

• at least one pair of rails, which are guided on opposite housing walls parallel to each other, and
• at least one first stabilizer body disposed on at least one of the rails on the housing facing side for affixing a backlashed fit or resilient abutment to at least one predetermined stabilized position for the extended condition of the rail with at least one second stationary stabilizer body mounted in a rail-facing manner form.

In this case, at least one stabilization position can additionally be provided for the retracted state of the rail. However, stabilization positions can also be provided in several or all driving states of the rail.

In this case, in particular at least one stabilization position for the extended state and / or at least one stabilization position for the retracted state of the rail is provided. But they can also be provided in several or all driving conditions of the rail.

The second stabilizing body is preferably arranged in the region of the housing wall releasing a housing opening or of a guide element for the rail facing the housing opening. Each stabilization position is associated with a respective first stabilizing body, wherein along the guide path of the rail preferably discrete or continuously extending first stabilizing bodies are arranged.

In particular, fits and / or resilient arrangements are distributed over a plurality of stabilization positions, wherein the matches provided for fits and / or the forces provided by resilient arrangements can each differ from one another.

The first and / or second stabilizing body are in particular resilient and are preferably made of elastic plastic.

The first stabilizing bodies are preferably arranged on both opposite rails in order to cooperate in stabilizing positions with corresponding second stabilizing bodies in a suitable and / or resilient manner, which preferably corresponds to a mirror-inverted arrangement.

The invention will be explained in more detail below with reference to two exemplary embodiments. In the accompanying schematic drawings show:

• Fig. 1 a washing compartment of a dishwasher with extended rails in stabilizing position according to a first embodiment seen obliquely from the left,
• Fig. 2 the extended rail in stabilization position as a detail seen from above,
• Fig. 3 the rail in an enlarged view,
• Fig. 4 a carrier with guide rollers and stabilizing body according to a second embodiment seen from obliquely forward,
• Fig. 5 a rail with stabilizing body according to the second embodiment seen obliquely from the left,
• Fig. 6 the guided rail is seen from above in a clearance fitting position between two resilient stabilization positions,
• Fig. 7 a washing compartment with the carrier, the rail and its stabilizing body viewed obliquely from above,
• Fig. 8 the rail in the extended state in side view from the inside and
• Fig. 9 the rail in the retracted state.

According to the FIGS. 1 to 3 are on opposite walls 2 of a housing part 4 between rollers (wheels) 6 rails 8 out.

The housing part 4 is U-shaped. It delimits to the rear and to the sides a washing compartment 10 of an otherwise not shown dishwasher. Forward there is a feed opening 12 free, which is closed by a pivot door, not shown, from bottom to top.

The rollers 6 are arranged in pairs on carriers 14, which in turn are attached to the walls 2. Each rail 8 is guided between the rollers 6 of two pairs of rollers spaced apart in the guide direction.

In the rails 8 run rollers (wheels) 16, which lead a direction indicated by struts 18 dish rack.

A frame 20 which closes off the housing part 4 at the front has an inwardly projecting section 22 which forms a second stabilizing body which is fixed in space. On the rail 8, a curved in the direction of the housing 2 first body 24 is disposed on the housing-facing side, which forms a first stabilizing body. Its position is chosen along the rail 8 such that it is opposite to the section 22 when the rail 8 is extended. His strength is tuned that he presses the portion 22 of the frame 20 and thus the wall 2 of the housing part 4 slightly outward in rigid training or is slightly compressed in elastic training by the portion 22. In both cases, there is a rail 8 and thus the crockery basket stabilizing effect. This all the more, if the opposite rail 8 should be equipped in the same way. Additionally or alternatively, an elastically formed section 22 or an elastic body accommodated therein could serve as a space-stable stabilizing body, which would be compressed by the body 24 arranged on the rail 8 and correspondingly dimensioned in its thickness.

According to the FIGS. 4 to 9 is on the support 14 on the rail-facing side between the rollers 6 in the direction of rail 8 buckling hemispherical body 26 is arranged, while extending on the housing-side of the rail 8, a direction wall 2 buckling elongated body 28, the end portions 30 are more curved as its central portion 32. The body 26 and / or the body 28 are elastic. The mutual distance of the two end portions 30 is selected so that in the retracted state ( Fig. 9 ) of the rail 8, the front end portion 30 and in the extended state ( Fig. 8 ), the rear end portion 30 is opposite to the body 26, wherein depending on the thickness and curvature of the end portions 30 and the body 26 both resiliently abut each other or at least form a slight mutual game, which also acts stabilizing. Depending on whether the end portions 30 spring or play interacting with the body 26 cooperates, also between the central portion 30 of the body 28 and the body 26, a lesser or greater game or a resilient system, when the rail 8 moved from the retracted to the extended state ( Fig. 6 ).
