Description

The present invention relates to a dishwasher, in particular household dishwasher, with a washing container whose feed opening can be closed by a door.

When closed, the door of a dishwasher is usually locked by a door lock. In order to open the door, it is usually necessary to apply a minimum tensile force to the door. Only from this minimum tensile strength of the door lock releases its lock. In practice, this may not be sufficient, an accidental opening of the door z. B. by a child to prevent.

The object of the invention is to provide a dishwasher, in particular a household dishwasher, in which unintentional opening of the door of the dishwasher can be prevented simply and cost-effectively.

This object is achieved in a dishwasher, in particular domestic dishwasher, of the type mentioned above in that the rinsing container, in particular at the front edge region, preferably Spülbehälterrandelement or Spülbehälterrahmen, or on the door a door lock is provided which comprises a movable closing piston, and that Limiting device is provided which blocks the movement of the closing piston in a first position and releases the movement of the closing piston in a second position.

The additional limiting device provides reliable and simple protection against unintentional opening of the door of the dishwasher. It can serve in particular as a cost parental control.

Preferably on the rinsing container, in particular on its front edge region, preferably front rinsing container edge element or on the rinsing container frame, the dishwasher or alternatively on its door, in particular interior door or door frame, a door lock is provided which denotes a movable closing piston, also referred to as a closing cam, includes. Due to its movable mounting, the closing piston in a first position, in particular when the door is brought into its closing end position, can counteract an elevator force when opening the door with a predetermined closing force. In a second position, the closing piston releases the movement of the door. Particularly preferably, the closing piston is guided linearly movable. In particular, a linear guide for the closing piston is provided in the housing of the door lock.

By the limiting device, the movement of the closing piston can be prevented. That is, the restriction device may block the movement of the closing piston in a first position (locking position or blocking position). By the limiting device, the closing piston can be kept in particular in a locking position or blocking position, whereby opening the door of the dishwasher is prevented in the final closing position. In other words, the door can only be opened if, in the release position of the limiting device, the closing piston is not blocked but remains movable. When the limiting device is in its release position, the closing piston is freely movable in such a way that when opening the door of the closing piston by contact with the door, in particular its inner door or door frame, or an increase or a projection on the door, the door frame or the Inner door is moved, in particular, is pushed back away from the feed opening of the washing, so that the door can be opened further. If the limiting device blocks the movement of the closing piston in its locking position, it remains in its locking position or blocking position and thereby prevents the door from being opened. In a second position (release position), the limiting device does not block the movement of the closing piston of the door lock, so that the closing piston remains freely movable and the door can be opened accordingly.

The limiting device is thus designed such that it can be brought into at least two positions, in particular in a locking position and a release position. In the first position, the limiting device blocks the movement of the closing piston of the door lock, in the second position, the limiting device does not block the movement of the closing piston, but releases it.

The limiting device is an additional safeguard that can prevent unintentional opening of the door of the dishwasher. Only when the Limiting device in the second position, the door of the dishwasher can be opened. By blocking the movement of the closing piston of the door lock can be prevented in a simple way opening the door of the dishwasher. Only by the release of the movement of the closing piston, ie by a transfer of the limiting device from the first position to the second position, the closing piston is free in its movement and the door can be opened by applying a certain opening tensile force on the door.

The dishwasher may be formed according to an expedient development of the invention, in particular for installation in a niche. A niche in the sense of the invention is in particular a recess in a piece of furniture, for example in a kitchen unit, which is designed to accommodate a fitted dishwashing machine, in particular a built-in household dishwasher. The niche, for example, at least partially formed by cabinet walls and / or a worktop. The niche can also be formed only by a cover plate, under which the dishwasher is arranged. According to a further expedient development of the invention, the dishwasher can alternatively be designed, in particular, as a tabletop device or as a solo stand device.

According to an expedient development of the invention, it can be provided in the dishwasher that the limiting device on the washing compartment, in particular on the front edge region, preferably Spülbehälterrandelement or Spülbehälterrahmen, or on the housing of the door lock, or alternatively on the door, in particular the inner door or door frame, preferred Door frame element, sliding, pivoting and / or rotatably supported. That is, the limiting device is displaceable from the first to the second position, pivotable and / or rotatable, and vice versa. For example, the limiting device can be held displaceably in a guide. In a first position, ie blocking position, such a limiting device is arranged in the guide such that the limiting device blocks the movement of the closing piston of the door lock. The limiting device preferably contacts the closing piston by touching it. If the limiting device is pushed or pulled from the first position to the second position (release position), then the limiting device no longer blocks the closing piston, but releases the sliding or travel path for it, and this can open the door due to its free mobility allow. For example, such a limiting device may be formed as an elongated profile body which is held feasible in a sliding guide. In this case, the limiting device can preferably be arranged on the washing container, in particular on its front edge region, preferably washing container edge element or washing container frame, expediently on the outside of the washing container facing away from the loading opening of the washing container in the region of the closing piston or its housing. Alternatively, the limiting device may preferably be provided directly on the door lock, in particular on the housing of the door lock. This has, inter alia, the advantage that only a single attachment to the washing container, in particular at its front edge region, preferably Spülbehälterrandelement or Spülbehälterrahmen is required. That is, it is only necessary to attach the housing of the door lock on the washing container, in particular at the front edge region, preferably Spülbehälterrandelement or Spülbehälterrahmen, preferably on the outside, preferably on the top side of the top wall of the Spülbehälters, since the limiting device arranged on the housing of the door lock as an additional component is. In particular, the limiting device can already be attached to the door lock housing before the door lock or the door lock housing is fastened to the front edge zone of the washing container. As a result, the door lock and the limiting device form a coherent unit. This saves mounting effort and thus also assembly costs. In general terms, the fastening device can be provided in the region of the door lock on the washing container, on its front edge region or washing container frame, or on the door lock itself. Alternatively, if necessary, it may alternatively also be attached to the door, in particular its inner door or door frame element, in the region of the point which interacts with the door lock on the washing container, in particular on its front edge region, preferably washing container rim or frame, in the closing end position of the door. preferably opposite.

Conveniently, the door lock with the closing piston in such a way at the upper edge portion of the front edge region of the cover wall of the washing, in particular in the central region, mounted that the closing piston in its release position, a substantially vertical upward and / or downward movement is possible. If z. B. closed the door, presses its inner door or door frame from a certain Zumachstellung or stop position during Zumachbewegung the pivoting door from below on the closing piston and pushes it into the housing of the door lock inside. It will a resilient element, in particular a coil spring, compressed and biased in the housing of the door lock. As soon as the door comes close to its closing end position during its closing motion and the closing piston faces a recess, in particular a closing recess, in the door, in particular inner door or door frame, preferably largely congruent at the upper edge portion of the inner door or door frame, the closing piston is due to the biasing force or Spring force of the resilient element in the housing of the door lock, downward, in particular vertically downward, in the preferably corresponding to the outer contour of the closing piston adapted inner contour of the recess, in particular closing recess, so that it is fitted to the inner contour of the closing recess form-fitting and there with a defined holding force or closing force is held. The closing piston sits in particular largely passport or positive fit in the closing recess. It is thus formed a tear or snap lock, in which the door can be raised only in overcoming this vertical-acting closing force by applying a correspondingly large tensile force on the door from its Schließendstellung out in an open position. As a result, reliable protection, in particular a child safety device, is provided against unintentional opening of the door.

In particular, it is expedient if the closing recess in the closing end position of the door viewed from the front has a rear slope or flank, which is steeper than its front slope or flank. Accordingly, the closing piston expediently has a rear slope or flank, which essentially corresponds to the steepness of the rear slope or flank of the closing recess, and a front slope or flank, which essentially corresponds to the steepness of the front slope or flank of the closure recess equivalent. The closing piston is thus formed on the front side with a flatter fold or slope than on its rear or rear side. As a result, slide the front bevels of the closing piston and the closing recess when closing the door smoothly with the application of a small horizontal sliding force component to each other, while the opposite when opening or pulling the door from the Schließendstellung out a larger minimum traction is required. Because for a sliding against each other of the rear, abutting flanks of closing piston and closing recess and thus pushing back the closing piston in a release position in the door lock housing in such a larger tensile force in the horizontal direction is required that against the vertically downward spring biasing force of the spring element of the door lock a vertical upward force component (through the forward, away from the feed opening door) is feasible, which is greater than this spring biasing force of the spring element. The greater the steepness of the abutting rear flanks of closing piston and closing recess, the greater is their holding force to each other in a forward, horizontal elevator movement of the door and the greater the applied tensile force to open the door.

Alternatively, the door lock may also be attached to the door, in particular its inner door or door frame element, preferably on the upper edge, preferably in the middle region, and with a recess corresponding to the position, in particular closing recess, at the front inner edge of the washing container, in particular the front Spülbehälterrand- or Spülbehälterrahmenelements, cooperate. The limiting device can then preferably be part of the door lock, or be provided on the door, in particular its inner door or door frame, or in the region of the recess on the washing container, in particular on the front Spülbehälterrand or frame. The closing piston is movably mounted in the door lock housing in the direction of the front inner edge zone of the washing container, in particular its front Spülbehälterrahmens or Spülbehälterrandelements, under a spring bias. In particular, it is pressed by a spring element in the door lock housing in the direction of the recess, in particular closing recess, which in this alternative embodiment z. B. on the washing compartment facing the inside of the front Spülbehälterrands or possibly the Spülbehälterrahmenelements the door lock opposite, in particular is arranged approximately centrally.

Alternatively, or in addition to a slide-movable arrangement of the limiting device, this can in particular be pivotally mounted on the washing container, in particular on the outside of its front edge region or attached there door lock housing itself, or alternatively on the door, in particular its inner door or door frame element. In this case, the limiting device can be held, for example, displaceable and at the same time pivotable. Thus, after a first displacement of the limiting device, for example, by a subsequent pivoting the limiting device can be moved from the first, blocking position to the second position.

Particularly preferred is a dishwasher, in which the limiting device the front or front edge region of the washing container or the housing of the door lock is only pivotally mounted about an axis of rotation. This represents a particularly simple and inexpensive storage of the limiting device. The limiting device can be pivoted between the first and the second position.

Furthermore, the limiting device may preferably be mounted rotatably. Thus, the limiting device may be formed, for example, as a circular disc with at least one recess. The circular disc is preferably rotatably mounted about its longitudinal axis. If the recess of the disc is arranged in alignment with the locking pin, this does not block the locking pin in its movement. If the recess of the disc is not arranged in alignment with the locking pin, the disc blocks the locking pin, so that it can not be moved. If the locking pin in the Schließendposition in which he locks the door, and the limiting means in the first position in which it prevents movement of the locking bolt, the door can not be opened due to the immobility of the locking bolt. The door of the dishwasher can only be opened again when the locking pin is no longer blocked by the limiting device. The simple rotation, pivoting and / or displacement of the limiting device is a simple and effective additional assurance of the door given.

The limiting device can therefore be designed differently. The limiting device is in particular designed such that it can be actuated relatively easily by a user of the dishwasher, ie that the user can easily bring the limiting device from the first to the second position, or vice versa. In the installed state of the dishwasher in an installation niche, however, the limiting device is preferably arranged on the dishwasher such that it is not immediately visible, so that unauthorized persons, in particular children, can not immediately recognize them. As already stated, the limiting device can be designed, for example, as a rotatably mounted disk or as a longitudinal profile that is displaceable, in particular in the width direction of the washing container. According to a particularly expedient development of the invention can be provided in the dishwasher that the limiting device is designed as a lever. One end of the lever is preferably rotatably mounted about an axis of rotation at the front edge region of the washing container, or on the door lock housing, or alternatively on the door. At the other end of the can Lever for pivoting preferably be gripped. The lever preferably has a planar base body whose position plane is arranged substantially perpendicular to the direction of movement of the latch bolt of the door lock. The main body has in particular an elongated, plate-shaped profile. In the first position of the lever of the main body blocks the movement of the locking bolt by the body is placed directly in front of the locking pin. As a result, it can no longer move because it abuts against the main body of the lever. In the second position, the lever is arranged such that it can no longer block a movement of the locking bolt of the door lock. In this case, the lever is preferably arranged in a plane parallel to one side of the housing of the door lock, in particular to the side facing away from the Spülbehälterinneren the door lock housing, pivotally.

According to a further expedient development of the invention, it can be provided in the dishwasher that the limiting device covers in its first position, ie blocking or locking position, a first passage opening in the housing of the door lock, through which the end of the closing piston which faces the closing piston, allocated closing recess facing away, otherwise it can be passed in the release position of the limiting device. In the final closing position of the door, the locking bolt or closing piston is pressed by a spring element, in particular in the housing of the door lock, in the direction of a facing depression, in particular the closing recess of the door, preferably its door frame element, and held there. In particular, this depression has an inner contour that largely corresponds to the outer contour of the free end of the closing piston facing it, which is pressed out in the direction of the recess from the door lock housing by the spring element in the closing end position of the door. If the limiting device covers the passage opening in the housing at the opposite end of the closing piston facing away from the recess, then it is locked or blocked in its closed position. If the limiting device is removed from this passage opening, the end of the closing piston remote from the recess can be pushed back into the housing of the door lock through the passage opening, whereby the spring element provided in the housing of the door lock is compressed and the spring projection exerted by it on the closing piston is increased. When opening the door of the dishwasher is generally considered the locking bolt preferably passed through a through hole in the housing of the door lock, so that the Recess facing away from the end of the locking bolt in the pushed-back position of the locking bolt protrudes from the housing of the door lock on its side facing away from the recess. If the limiting device is rotated, pivoted and / or pushed into the first position, a region of the limiting device covers this through-opening. As a result, the recess facing away from the end of the locking bolt can not be led out of the interior of the door lock housing, ie the locking pin is held in the position in which he locks the door. The locking pin of the door lock is preferably acted upon by a clamping force, which always guides the locking pin in the direction of the Spülbehälterinneren. By the contour of the door of the dishwasher of the Spülbehälterinneren facing away from the locking bolt when opening the door against the clamping force acting on the locking bolt moves, in particular linearly, preferably vertically, moved, and at least partially passed through the passage opening of the door lock housing if this is not prevented by the limitation device.

According to a further particularly expedient development of the invention, it can be provided in the dishwasher that the movement of the delimiting device is restricted by at least one delimiting element. Restriction of the movement of the limiting device means in particular that the first and the second position of the limiting device preferably represent the respective end positions of the limiting device. In this case, the respective limiting element can be designed and arranged such that it prevents further rotation, displacement and / or pivoting when the first or the second position of the limiting device is reached. As a result, the user of the dishwasher knows that the locking pin of the door lock is blocked or is not blocked. The limiting means, such as a lever, in particular abuts against the restriction member when the end positions, i. the first or the second position, the limiting device are reached. By the stop of the limiting device on the limiting element, the user feels that the dishwasher is additionally secured against unintentional opening of the door, or not. For example, the limiting element may be formed by two stops projecting on the outside of the door lock housing, in particular bolts or pins.

In particular, it may be expedient if at least one haptic element, in particular a survey, preferably nose, between the first and the second position of the limiting device on the housing of the door lock or on the washing container, in particular at the front edge region, in particular front Spülbehälterrahmen or front edge element, or alternatively on the door, in particular its inner door or door frame element provided is. This allows a user to sense whether the limiting device has reached the second position when changing from the first position to the second position (and vice versa), ie when moving the limiting device from the first to the second position and vice versa, the user receives a haptic feedback.

Furthermore, in a further, particularly expedient embodiment of the invention, it can be provided in the dishwasher that a holding-down device is provided on the side of the delimiting device facing away from the closing piston, which prevents movement of the delimiting device in the direction of extension of the closing piston. That is, the hold-down prevents the limiting device can be moved by the locking pin. The hold-down supports the limiting device and ensures that it can not be moved parallel to the extension direction of the locking bolt. The hold-down device is designed, for example, as an angle-shaped, in particular hook-shaped, component that is arranged on the washing container, in particular on its front edge region, or on the outer housing of the door lock. The free end of the angle-shaped component is preferably arranged such that at least in the first position of the limiting device, this rests positively between the outside of the door lock housing and the free end of the angle-shaped component at the free end. In another advantageous embodiment of the hold-down device, this can be designed as a bridge-like element, which is preferably arranged on the outside of the front edge region of the washing container or of the door lock housing. The limiting device, in particular the lever, is movable between the pillars / legs of the bridge-like element. The locking pin facing away from the side of the limiting device is guided directly on the inside of the pillar / leg connecting base part of the bridge-like element along. As a result, the bridge-like element ensures that the limiting device, in particular the lever, can only be pivoted, displaced and / or rotated in one plane, but can not be moved perpendicular to this plane. The hold-down counteracts the force acting on the lock pin when the door is unintentionally opened.

According to a further expedient development of the invention, it can be provided in the dishwasher that the delimiting device comprises a main body and a bearing pin arranged in particular perpendicularly to the main body, for pivotally and / or rotatably supporting the limiting device in a bore in the front Edge region of the washing compartment or the housing of the door lock is mounted. The bearing pin preferably has a cylindrical profile and is positively mounted, pivotally and / or rotatably mounted in a bore in the front Spülbehälterrandbereich or the housing of the door lock. The bore is arranged in particular on the side facing away from the Spülbehälterinneren side of the front Spülbehälterrandbereichs or the door lock housing in this. Preferably, the bearing pin of the limiting device is arranged perpendicular to the base body of the limiting device at this. If the limiting device is designed, for example, as a circular disk, then the bearing pin preferably extends axially parallel or coaxially to the longitudinal axis of the disk. If the limiting device is alternatively designed as an elongated lever, the bearing pin is preferably arranged at one end of the main body of the lever at this, in particular perpendicular to this. The other end of the main body of the lever is used in particular as a handle for pivoting the lever.

According to a further, particularly expedient development of the invention, it can be provided in the dishwasher that the limiting device is displaceably, pivotably and / or rotatably arranged in a plane which runs perpendicular to the extension direction of the closing piston. Preferably, the outside of the door lock housing, which faces away from the Spülbehälterinneren, flat. The locking pin is displaceable in particular perpendicular to the flat outer side of the housing of the door lock. In this case, the locking bolt can preferably be passed through a passage opening in the housing of the door lock, when it is pushed back when opening the door by this. The limiting device is preferably in a plane parallel to the flat outer side of the door lock housing, which faces away from the Spülbehälterinneren, slidably, pivotably and / or rotatably mounted. As a result, the limiting device can cover the passage opening in the outer side of the door lock housing in its first position, so that the locking bolt can not be led out of the passage opening or through bore.

According to a further expedient development of the invention, it can be provided in the dishwasher that the limiting device comprises a handle for carrying out a displacement, pivoting and / or rotation. The handle serves to allow a user of the dishwasher, who would like to additionally secure the dishwasher against unintentional opening, to grasp and operate the limiting device easily. For example, one end of an elongate lever may serve as a handle. Preferably, an additional handle is arranged on the limiting device. This can for example be arranged inclined to the main body of the limiting device at this.

According to an additional expedient development of the invention can be provided in the dishwasher that the limiting device is arranged on the washing container or the housing of the door lock, which is the handle in the closed state of the door above the door frame of the door, in particular the outer door arranged. The dishwasher is designed for installation in a niche. In the installed state, in particular only the front side of the dishwasher, on which the door is pivotally or slidably mounted, is visible to a user. The limiting device or the handle of the limiting device is therefore preferably arranged accessible above the frame of the door and below a top wall of the niche, for example below a worktop. As a result, the limiting device is not immediately visible, but can still easily be gripped and operated by a user who knows the limiting device.

According to a further particularly expedient development of the invention, it can be provided in the dishwasher that the delimiting device pushes non-positively, in particular by a latching or clamping connection, on the washing container, in particular on its front washing container edge region, preferably front edge element or washing container frame, or the door lock housing attached there. , is pivotally mounted and / or rotatably mounted. So that the limiting device sits securely on the washing container or the door lock housing, this is preferably fixed non-positively on the washing or the door lock housing. Preferably, the bearing pin of the limiting device on one or more locking or clamping elements, which in corresponding one or more indentations or grooves on the inner contour of a bore in the washing, in particular the front Spülbehälterrands or - frame or attached there Snap the door lock housing into which the bearing pin is inserted. For example, a circumferential or partially circumferential groove may be provided on the inner contour of the bore. In particular, the groove biases a plane which runs perpendicular to the longitudinal axis of the bore. The one or more locking elements of the bearing bolt snap into the at least one indentation or groove of the bore and thus hold the limiting device rotatable or pivotable on the washing container or the door lock housing.

According to a further particularly expedient development of the invention, it can be provided in the dishwasher that the delimiting device comprises a plastic material or a metal. Preferably, a plastic material is used for the limiting device. Such a limiting device can be produced, for example, simply by a casting method, in particular an injection molding method. In this case, the bearing pin and possibly the handle can be made in one piece, in particular monolithic, with the main body of the limiting device. Alternatively, the bearing pin can be subsequently attached to the main body of the limiting device. In the case of a basic body formed from metal, the bearing bolt can be fastened to it in a material-locking manner, for example by a welded or adhesive connection.

The invention also relates to a door lock for closing the door of a dishwasher, in particular domestic dishwasher, which is characterized in that it comprises a limiting device or a limiting device can be attached to it, which blocks the movement of the closing piston of the door lock in a first position and in a second Position the movement of the closing piston releases.

Other embodiments and further developments of the invention are given in the dependent claims. The above-described embodiments and further developments of the invention and the developments according to the subclaims can be used both individually and in any combination in the dishwasher according to the invention.

The invention and its developments and advantages thereof are described below with reference to Drawings explained in more detail.

Fig. 1 schematically shows a perspective view of an advantageous embodiment of a dishwasher 1, in particular domestic dishwasher, which according to the design principle according to the invention comprises a limiting device 6 for additional securing the household dishwasher 1. It can be used in particular as a built-in device for installation in a niche such. As a kitchenette or a kitchen cabinet, be designed as a tabletop device, or stand-alone device. The household dishwasher 1 has a washing container 20. The rinsing container 20 is composed of a vertically arranged rinsing container rear wall 223, two rinsing container side walls 221, 222 arranged at the two side edges of the rinsing container rear wall 223 perpendicular to the latter, and a rinsing container ceiling wall 224 and a bottom tray 25. In particular, it may be composed of a U-shaped hood 221, 222, 224 and the rear wall 223. The washing container 20 is mounted on a base assembly 10, also referred to as a base support. That is, in the height direction or in the z-direction of the illustrated x, y, z coordinate system, the bottom assembly 10 is arranged below the washing container 20. The floor assembly 10 makes contact with a substrate, in particular a kitchen worktop in the case of a table dishwasher or to the bottom of an installation niche in the case of a built-in dishwasher. The rinsing container can be surrounded in addition to its inner housing with an outer housing, in particular if the dishwasher is designed as a stand-alone unit or tabletop unit. The washing compartment has on its front side a charging opening for charging the one or more dishwashing baskets 200 to be cleaned in the washing compartment of the washing compartment with items to be cleaned. The front-side charging opening 21 of the washing container 20 can be closed by a door 30. The door 30 is pivotally supported by support pins provided on retainers of the floor assembly 10.

The loading opening 21 is thus opened to load the one or more baskets by a door 30 attached to the dishwasher 1 and to operate the Dishwasher closed by the attached to the dishwasher 1 door 30. In particular, in household dishwashers, the loading opening is usually arranged at the front, so that the door is usually in the lower portion of the washing, in particular on the bottom assembly of the domestic dishwasher, pivotally mounted or alternatively extendable -like a drawer attached.

The washing container 20 has a front washing container edge region 22. This is frontally viewed from the front U-shaped and extends along the front end sides of the two side walls 221, 222 and the top wall 224. At the front edge of the washing can possibly an additional edge element or Spülbehälterrahmenelement only locally at selected locations, only partially, or be provided throughout along its entire length. It may in particular serve to ensure a sufficient mechanical stability of the washing container 20 and / or to provide a sealing bed for a door 30. If necessary, this front edge zone 22 of the washing container can be designed to fasten the dishwasher 1 in an installation niche, in particular in a niche of a kitchen unit. The front Spülbehälterrandbereich 22 may preferably be formed stiff. At the upper portion 23 of the Spülbehälterrandbereichs 22, ie at the front, extending substantially in the depth and width direction y, x edge portion 23 (see FIG. 4 ) of the top wall 224 of the washing container 20, here in the FIG. 1 shown only schematically, a door lock 3 with an associated limiting device 6 is provided. FIG. 4 shows the door lock 3 on the upper outer side 23 of the front Spülbehälterrandbereichs 22, which is arranged in the x, y-plane approximately parallel to the top wall 224, in perspective view. It is approximately centrally on the upper-side portion 23 of the Spülbehälterrandbereichs 22, in particular the possibly existing front edge element of the washing or Spülbehälterrahmenelements, mounted on the outside. It sits with its closing piston 4 preferably at the upper, horizontally or horizontally extending Spülbehälterrandbereich 23 that its closing piston 4 can penetrate or pass through an opening opening 220. Its closing piston 4 protrudes from the housing 5 of the door lock 3 through an opening 220 (see FIG FIG. 5 ) in the upper portion 23 of the front Spülbehälterrandbereichs 22, which is substantially vertically downwards as a spring-mounted snap-out element, which is associated with a recess or closing recess 32 at the top or top edge of the door frame 31, in particular door frame element, opposite (see FIG. 4 ). This upper edge portion 23 is the front Edge zone of the top wall 224 of the washing container 20, which lies in the installation or installation position of the dishwasher in a depth direction y and width direction x extending position plane. The recess or 32 has an inner contour which is formed substantially complementary to the outer contour of the lower end of the closing piston 4. The closing trough can be formed in the upper edge of the door frame 31, in particular door frame element, by an impression with. Alternatively, it may optionally be formed by a molded part, which is used as an independent component in a corresponding recess on the upper side of the door frame, in particular door frame element. The respective recess of this separate molding can be produced in a simple manufacturing manner with desired inner contours. Preferably, plastic is selected for this molded part with closing recess, so that it is possible to produce different shapes of closure molds in a simple, production-technically efficient and cost-effective manner. In the closing end position of the door 30, the closing piston 4 and the closing recess are largely aligned with each other. The front-side charging opening 21 of the washing container 20 can be closed by the door 30 by means of the door lock 3. The door 30 is pivotally mounted. In the closed state of the door 30, the limiting device 6 is arranged above the frame 31 of the door 30, so that it can be actuated by a user. In this final closing position of the door 30 whose door frame 31 dives partially or completely into the front Spülbehälterrand the Spülbehälters, so that the door frame 31 and the washing 20 come at least in a front edge zone to cover, ie overlap there.

The FIGS. 2 and 3 show a schematic plan view of the housing 5 of the door lock 3 and on the pivotally mounted on the housing 5 of the door lock 3 limiting device 6 of FIG. 1 , The limiting device 6 is formed in the present embodiment as an elongated lever. In this case, the main body 6b of the limiting device 6 extends in a plane x, y parallel to the upper side, flat outside of the housing 5 of the door lock 3. The schematically indicated by the cross bearing pin 6c of the limiting device 6 is inserted into a bore 9 in the housing 5 of the door lock 3 and pivotally mounted in this bore 9. The bearing pin 6c is preferably held in the bore 9 by at least one snap connection. In the FIGS. 2 and 3 the limiting device 6 is viewed from above viewed in two positions. FIG. 2 shows the limiting device 6 in a first position (blocking position) 10. In this first position 10, the body covers 6b of the limiting device 6, a the interior of the washing container facing away through opening 5a in the door lock housing 5, which is indicated by dash-dotted lines, from above as a kind of cover from. The passage opening 5a extends substantially in the vertical direction z. It forms the imaginary extension of an opening opening 220 in the upper longitudinal section 23 of the front Spülbehälterrandbereichs 22, ie it sits largely aligned above this. If the limiting device 6 sits over the aperture 220 and covers it, which can in the FIGS. 2, 3 Not shown locking bolt or closing piston 4 of the door lock 3 is not pushed out of its locking position 10, in which it is pressed into the closing recess 32, from the washing compartment interior facing away from the opening 5a upwards or led out. The limiting device 6 blocks in this first position 10, the upward movement of the locking bolt 4 so that it does not release the locking of the door 30 of the dishwasher 1 by the locking pin 4 and the door 30 can not be opened. The locking pin 4 of the door lock 3 is linearly or longitudinally displaceably mounted in the door lock housing 5 in the passage opening 5a (see FIG. 5 ). In particular, it is arranged coaxially in the passage opening or through-hole 5a of the door lock housing 5. In FIG. 2 is the second position (release position) 11 of the limiting device 6 shown in phantom. In this second position 11, the main body 6b of the limiting device 6 does not cover the through opening 5a in the door lock housing 5, but releases it completely, so that the movement of the locking bolt 4 can not be blocked. The limiting device 6 can be pivoted between this first position 10 and this second position 11.

On the side facing away from the closing piston or locking block 4 side 6a of the limiting device 6, a hold-down 8 is additionally provided at the top of the housing 5 of the door lock 3. This holding-down device 8 ensures from the outside that the limiting device 6 can not be bent or lifted out of the bore 9 in the housing 5 of the door lock 3 by the force acting on the locking pin 4 when attempting to open the door 30 of the domestic dishwasher 1. The holding-down device 8 is arranged on the upper side 6a of the delimiting device 6 such that the base body 6b of the delimiting device 6 slides along the underside of the hold-down device 8 when it is pivoted from the first position (blocking position) 10 into the second position (release position) 11 , or the other way around. The hold-down 8 serves in this embodiment simultaneously as a lateral limiting element 7 for the pivoting movement the limiting device 6 along the housing 5 of the door lock 3. He is here formed bridge-shaped. The peripheral pillars / legs of the bridge-shaped hold-down 8 form the delimiting elements 7 and limit the pivoting movement of the limiting device 6. If the delimiting device 6 strikes the outer legs 7 of the hold-down 8, the user of the household dishwasher 1 is indicated, in particular haptically marked, that the first position 10 or the second position 11 of the limiting device 6 is reached.

In the FIG. 3 is the limiting device 6 in the second position (release position) 11, in which this does not cover the through hole 5a in the housing 5 of the door lock 3, but completely releases, so that the through hole 5a is open on the upper side. The blocking first position 10 is in the FIG. 3 shown in phantom. At the (viewed from the front) rear end of the main body 6b of the limiting device 6, this is pivotally mounted. At the other, protruding forward end of the base body 6b of the limiting device 6 is a handle 6d (see also FIG. 5 ) is provided, which can be used to pivot the limiting device 6 by a user.

Generally speaking, the restriction device may have various shapes. Thus, the limiting device may be formed, for example, as an elongated profile which is displaceably mounted in or on the housing of the door lock. In a first position of the displaceably guided limiting device, the limiting device blocks the movement of the closing piston of the door lock. By a displacement of the limiting device in a second position, the movement of the locking pin is released. Alternatively, the limiting device may be formed as a circular disk. This is preferably mounted by means of a bearing pin on the disc rotatably mounted about an axis of rotation. The disc may have a recess or passage opening through which the locking bolt can be passed when the disc has reached the second position. That is, the recess is arranged in the second position in alignment with the passage opening in the housing of the door lock. By rotation of the disc, the base body of the disc can cover the passage opening, so that the movement of the latch bolt of the door lock can be prevented and thereby the opening of the door of the built-in household dishwasher can be prevented.

Fig. 4 schematically shows a perspective view of the upper portion of the feed opening 21 of the holding dishwasher 1 of FIG. 1 when its door 30 is brought into an open position in which the door frame 31 in the region of the upper portion 23 of the front Spülbehälterrandbereichs 22 no longer immersed in this. At this upper portion 23 of the front Spülbehälterrandbereichs 22, the door lock sits outside approximately centrally located. On the housing 5 of the door lock 3, the pivotally mounted limiting device 6 is additionally attached. The locking pin 3, not shown, of the door lock 3 engages in the closing end position of the door 30 (see FIG. 2 and FIG. 5 ), in which it closes the charging opening 21 of the washing container 20, due to a clamping force F _s acting on the locking bolt 4 into the recess 32, which is arranged at the top of the door frame 31 corresponding to the position of the locking bolt 4, ie approximately centrally here, and thereby locks the door 30 in the closing end position, see Fig. 5 ,

FIG. 5 schematically shows a side cross-section through the arranged on the front Spülbehälterrandbereich 22 door lock 3 and arranged on the housing 5 of the door lock 3 limiting device 6 of the domestic dishwasher 1. In this illustration, the door lock 3 locks the door 30 in its Schließendposition. A first, lower end of the latch bolt 4 is seated in the recess 32 in the door frame 31 of the door 30 a. The second, upper end of the locking bolt 4 is arranged in the passage opening 5 a of the housing 5 of the door lock 3. When opening the door 30, the locking bolt 4 would be pushed back by the contour of the door frame 31 in the passage opening of the door lock housing 5 and at least partially led out through the through hole 5a of the housing 5 from the housing 5 upwards. In the FIG. 5 is located on the housing 5 of the door lock 3 pivotally mounted limiting device 6 in the first position 10 (blocking position) and thereby prevents the locking pin 4 can be led out through the through hole 5a from the housing 5. That is, the limiting device 6 blocks the linear, in particular vertical, displacement of the locking bolt 4 along the linear guide 12 of the door lock 3. This allows the locking pin 4 is not pushed back by the contour of the door frame 31 from the recess 32 in the vertical direction away from the washing so that the latch bolt 4 remains in the final-closing position and prevents the opening of the door 30. The limiting device 6 is pivotally mounted in the bore 9 in the housing 5 of the door lock 3 via its support pin 6c. The limiting device 6 can be pivoted via the handle 6d projecting to the front. The door lock 3 comprises in this embodiment, a resilient element 13, in particular a spring which exerts a clamping force F _s in the direction of the door 30 and the feed opening 21 of the washing container 20 on the locking pin 4. The clamping force F _s ensures that the locking pin 4 dips into the recess 32 in the frame 31 of the door 30 and realizes the locking of the door 30 when the door assumes its closed end position.

In the FIGS. 6 to 8 In each case, different perspective views are schematically illustrated on the door lock 3 arranged on the outside on the upper section 23 of the washing compartment edge region 22 and on the limiting device 6 arranged on the housing 5 of the door lock 3. In the FIG. 6 a side section through the door lock 3 and the limiting device 6 is shown. The bearing pin 6 c of the limiting device 6 is rotatably mounted in the bore 9 of the housing 5 of the door lock 3. As a result, the limiting device 6 can be pivoted. The basic body 6b of the delimiting device 6 runs along the upper outer side of the housing 5 of the door lock 3. In this embodiment variant of the domestic dishwasher 1, the limiting device 6 has a projection 14, also referred to as a nose. This projection 14 is movably seated in the bow-shaped hold-down 8. That is, the hold-down 8 ensures that the limiting device 6 can not be raised by the locking pin 4, here vertically upwards. The two outer or lateral legs of the bow-shaped hold-down 8 represent lateral limiting elements 7, which limit the pivoting movement of the limiting device 6 laterally. The limiting device 6 can be pivoted in a horizontal x, y pivot plane, ie parallel to the outside of the housing 5, until the projection 14 abuts one of the limiting elements 7. As a result, the user knows that the first position 10 or the second position 11 of the limiting device 6 has been reached. The housing 5 of the door lock 3 is preferably by a mechanical connection, in particular by a clamping or plug connection, preferably force-, form-, and / or fitting, attached to the Spülbehälterrandbereich 22. The housing 5 of the door lock 3 may alternatively or additionally be fastened to the rinsing container frame 22 by a cohesive connection.

FIG. 7 schematically also shows a side section through the door lock 3 and the limiting device 6. Here is clearly seen how the projection 14 of the limiting device 6 is guided in the hold-8. In this illustration, the limiting device 6 is in the second position 11, ie the limiting device 6 does not block the movement of the locking pin 4 of the door lock 3, but gives it completely free. An upper end of the latch bolt 4 is passed through the upper through hole 5a of the housing 5 and projects out of the housing 5 upwards. In this position of the latch bolt 4, the latch bolt 4 does not lock the door 30 of the built-in domestic dishwasher 1, because it is pushed back into the housing 5, so that the door can be opened. The locking pin 4 is pushed back up into the housing 5 from the upper edge 23 of the door frame 31 when closing the door 30 before reaching the final closing position and opening the door when leaving the corresponding recess 32 and thus makes each way the way for the door movement free. The hold-8 is formed bridge-shaped and arranged on the housing 5 of the door lock 3, in particular integrally formed on this. It extends in the width direction x over both position positions 10, 11 of the limiting device 6 (see also FIGS FIGS. 2, 3 ).

FIG. 8 shows a perspective top view of the arranged on the Spülbehälterrandbereich 22 door lock 3 and on the arranged on the housing 5 of the door lock 3 limiting device 6 of the domestic dishwasher 1. The handle 6d of the limiting device 6 protrudes beyond the Spülbehälterrandbereich 22 to the front, so that it by a Users can be gripped. The limiting device 6 is in the second position 11 (see FIG. 7 ), so that the passage opening 5a is not covered by the main body 6b of the limiting device 6. In this way, the locking pin 4 can be passed through the upper through hole 5a and emerge from the housing 5 of the door lock 3, when pressed from bottom to top against the bias of the spring element 13 in the housing 5 through the door frame 31 when opening or closing the door 30 is so that the spring tension of the spring element 13 is increased relative to the spring tension in the shooting end position of the closing piston 4 in the closing recess 32, with this tries to push the closing piston, in particular vertically, down. The downwardly directed projection 14 of the limiting device 6 is limited by the hold-down 8 and acting as limiting elements 7 legs of the blank holder 8 in its pivoting movement.

In particular, the following embodiment variant can be advantageous:
The additional assurance or child safety consists for example only of a lever, which is made in particular of plastic. A bearing pin of the lever can be inserted into a hole of the door lock from above. On the door lock housing is advantageously a hold-down. To operate the fuse, the lever in horizontal or horizontal plane, for example, by the finger of an operator or other object, such as a dipper, are moved. The lever preferably strikes against lateral limiting elements, which signals the user of the built-in domestic dishwasher the respective end position of the lever. If in the first position (blocking position) of the lever trying to open the door, the closing piston abuts against the underside of the lever, which in turn is limited by the hold-down (in particular against the lifting movement vertically upward), thereby preventing the door from opening , This represents a cost-effective and easy-to-use embodiment of an additional safeguard or child safety device of a dishwasher, in particular a domestic dishwasher. The dishwasher is preferably designed as a built-in household dishwasher. The dishwasher can also be designed as a tableware dishwasher. In particular, the dishwasher is installed in a niche of furniture, such as kitchen furniture.

In particular, it may be expedient that in addition at least one haptic element such as 40 (see FIGS. 2, 3 ), in particular a survey, preferably nose, between the first position 10 and the second position 11 of the limiting device on the housing of the door lock or on the washing container, in particular on the frontseitigem Spülbehälterrahmen or Spülbehälterrandelement - if applicable, or alternatively the door, in particular their Interior door, or door frame element, is provided.

Conveniently, the door lock 3 with the closing piston 4 in such a manner at the upper edge portion 23 of the front Spülbehälterrandbereichs 22, in particular in the middle region, attached that the closing piston in its release position, a substantially vertical upward and / or downward movement is possible. If z. B. the door 30 is closed, presses its inner door or door frame 31 from a certain Zumachstellung or stop position during Zumachbewegung the pivoting door from below on the closing piston 4 and pushes it into the housing 5 of the door lock 3 inside. In this case, a resilient element 13, in particular a coil spring, compressed and biased in the housing of the door lock 3. As soon as the door comes close to its closing end position during its closing movement and the closing piston 4 has a recess 32, in particular a closing recess, in the door, in particular Inner door or door frame 31, preferably located substantially congruent at the upper edge portion of the inner door or door frame, the closing piston is due to the biasing force or spring force F _{s of} the resilient element 13 in the housing 5 of the door lock 3, down, in particular vertically downwards, preferably in the to the outer contour of the closing piston correspondingly adapted inner contour of the recess, in particular closing recess, pressed so that it fits there conformed to the inner contour of the closing recess and is held there with a defined holding force or closing force. The closing piston sits in particular largely passport or positive fit in the closing recess. It is thus formed a tearing or snap lock, in which the door can only be raised by overcoming this vertically acting closing force F _s by applying a correspondingly large tensile force F _z on the door from its Schließendstellung out in an open position. As a result, reliable protection, in particular a child safety device, is provided against unintentional opening of the door.

In particular, it is expedient if the closing recess 32 in the closing end position of the door 30 viewed from the front has a rear slope or flank 321 which is steeper than its front slope or flank 322. Accordingly, the closing piston 4 expediently at its lower end on a rear slope or flank 41, which substantially corresponds to the steepness of the rear slope or flank 321 of the closing recess 32, and a front slope or flank 42, which substantially Slope of the front slope or flank 322 of the closing recess 32 corresponds. The closing piston is thus formed on the front side with a flatter fold or slope than on its rear side. This is in the side view of FIG. 5 shown schematically. As a result, slide the front bevels of the closing piston and the closing recess when closing the door smoothly with the application of a small horizontal sliding force component to each other, while the opposite when opening or pulling the door from the Schließendstellung out a larger minimum tensile force F _z (in y-direction forward) is required. Because for a sliding of the rear, abutting flanks of closing piston and closing recess and thus pushing back of the locking piston in a release position in the door lock housing into such a larger tensile force in the horizontal direction is required that against the vertically downward spring biasing force F _{s of} the spring element 13 of the Door lock is a vertically upward, force component (by the forward, away from the feed opening door) is effected, which is greater than this spring biasing force of the spring element. The bigger the Steepness of the adjacent rear flanks of closing piston and closing recess, the greater is their holding force against each other in a forward, horizontal elevator movement of the door and the greater the applied tensile force or tearing force F _z , which is applied to open the door.

Alternatively, the positions of the door lock 3 and closing recess 32 may also be reversed. The door lock may optionally also be attached to the door, in particular its inner door or door frame element, preferably on the upper edge, preferably in the middle region, and with a recesses provided for this purpose, in particular closing recess, on the front inner edge of the washing container, in particular on its possibly existing, front-side Spülbehälterrahmenelement or Spülbehälterrandelement, cooperate. The limiting device can then preferably be part of the door lock, or be provided on the door, in particular its inner door or door frame, or alternatively in the region of the recess on the washing container, in particular on the front-side Spülbehälterrahmen. The closing piston is movably mounted in the door lock housing in the direction of the front inner edge zone of the washing container, in particular its front Spülbehälterrahmens or - edge element, under an upwardly directed spring bias. In particular, it is pressed by a spring element in the door lock housing in the direction of the recess, in particular the closing recess, which in this alternative embodiment, e.g. at the washing compartment facing the inside of the front Spülbehälterrands or possibly the possibly existing front Spülbehälterrand- or Spülbehälterrahmenelements of the washing container opposite the door lock, in particular is arranged approximately centrally.

Furthermore, the limiting device 6 may advantageously be designed such that it can be removed, for example, in particular from the front rinsing container edge region 22 if it is not needed, for example because the user has no infants at home. The limiting device 6 is therefore designed to be detachable. If necessary, it can be re-attached to the rinsing container, in particular its front rinsing container frame element or edge element. It thus forms a Zusatzbehörteil to the dishwasher.
