Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a dishwasher designed for commercial use, in particular a device dishwasher or basket washer.

TECHNICAL BACKGROUND OF THE INVENTION

For commercial use designed dishwashers, hereinafter also commercial dishwashers are used in particular for washing dishes, glasses, cutlery, large rectangular trays, Euro standard baskets, pots or the like, as used for example in catering establishments, butchers, bakeries, pastry shops, etc. become. Such commercial dishwashers are characterized without loss of generality in that they are structurally designed to accommodate large quantities and / or large sized dishes.

Commercial dishwashers are generally designed as free-standing appliances, without restriction of generality, which have a table-like frame on which the dishwasher body is provided with a rinsing chamber provided therein. Below the washing chamber, the frame may have a machine housing for a pump, a water heater and / or an electronic control unit.

Usually commercial dishwashers for receiving large quantities and / or large-volume items to be washed have essentially cuboid wash chambers. The rinsing chambers normally have a width of 500 mm to 1500 mm, for example about 680 mm, a depth of 400 mm to 1000 mm, for example about 610 mm, and a height of 300 mm to 1000 mm, for example about 640 or 800 mm. Commercial dishwashers are usually loaded by means of one or more baskets, such as a basket of equipment or a small parts basket that hold the items to be washed. Flat or flat ware, such as dishes, trays, sheets, pot lid or the like, can be inserted edgewise in rinse baskets with inserts. For example, a basket may have a basket dimension (width by depth) of 650mm by 508mm, 608mm by 672mm, or 1260mm by 695mm.

For loading with items to be washed, a commercial dishwasher usually has a loading opening which can be closed by a door and which may also be referred to as a loading and unloading opening. Doors of conventional commercial dishwashers usually have at least one tilting door, which is folded up in the closed state of the dishwasher and which is opened in the open state of the dishwasher and protrudes from the bottom of the usually rectangular loading opening in the horizontal direction. The tilting door of a commercial dishwasher clamps a surface along the tilting axis both in the closing position and in the loading and unloading position, ie in a first horizontal direction. The direction in which the tilting door extends is therefore generally meant the direction perpendicular to the tilting axis of the tilting door.

Commercial dishwashers may also include a multi-unit door system including a tipping door and, for example, a folding door, wherein the folding door is movable to close or release the upper part of the loading opening. Such a dishwasher is for example off DE 42 38 372 A1 known.

Typically, industrial dishwashers with a wash basket are designed so that the wash basket is displaceable by means of a horizontal translational movement out of the sink onto the inside or top side of the tilting door. A washing basket can thus be pulled out by a user from the washing chamber of a commercial dishwasher and then stored on the inside of the tilting door facing upwards in the open state of the tilting door. There, the wash basket can be unloaded from cleaned items and loaded with items to be cleaned. Once the wash basket is loaded with items to be cleaned, the user can push it back into the washing chamber, close the single or multi-door of the dishwasher and start a flushing process.

For hygienic reasons, commercial dishwashers are usually cleaned daily of coarse dirt particles, such as food waste. For this purpose, the door of the dishwasher is opened and all items to be washed and optionally rinsing baskets removed from the dishwasher. Subsequently, a user accesses the interior of the dishwasher to clean it. To clean the rinsing chamber, it may be necessary for the user to remove components of the dishwasher arranged in the rinsing chamber, such as rinsing arms and sieves, and to clean them individually.

Due to the relatively large dimensions of the washing chamber, it may be difficult, especially for small people, on the entire interior of the washing chamber access. Also, especially for small people, the access to be removed components of the dishwasher as well as their replacement make it difficult. Furthermore, it has been found that during manual cleaning of the dishwasher often dirt particles are overlooked and thereby remain in the dishwasher.

Conventionally, the access to the washing chamber with open, brought in the horizontal direction tilting door, so that the user to clean the dishwasher either to the side next to be or must bend over the tipping door, which complicates the accessibility to the washing chamber.

The EP 2 491 844 A2 shows a dishwasher with a double door, which consists of a sliding door and a hinged door. The two door elements are connected to each other via a two-piece gear. The pivoting door member can be pivoted from a closed and vertical position to an open and horizontal position and from there to an open and vertical position. In the embodiments of the EP 2 491 844 A2 a releasable joint is used, wherein the releasable joint is positioned either between the lower end of the first gear and the upper end of the second gear, or at the lower end of the second gear.

The WO 2014/111827 A1 shows a hinge for a door that at least partially covers a compartment. The hinge comprises a fixed support connected to the frame of the compartment and a movable support connected to the door. The hinge also includes means for providing the movable support with a predefined movement relative to the fixed support during opening and / or closing of the door, and controlled motor means for assisting in opening and / or closing the door by a pressure and / or or tensile force on the movable support with respect to the solid support.

SUMMARY OF THE INVENTION

An object of the invention is to design a dishwasher so that the unhindered access to the rinsing chamber can take place. Furthermore, it is an object of the invention that the access to the washing chamber for the user can be done in a simple and secure manner.

One aspect of the invention relates to a (commercial) dishwasher, such as a dishwasher, whose tilting door for cleaning or maintenance of the dishwasher can be folded from a horizontal position to a vertical position in which the access to the rinsing chamber is possible. As a result, the surface is released immediately before the loading opening of the dishwasher and a user can thus access unhindered by the tilting door on the washing chamber and therein components of the dishwasher. In order to allow such a folding into a vertical position, the tilting door of the dishwasher next to a hinge for tilting the tilting door from the closed vertical position to the open horizontal position may comprise an additional folding hinge, with the aid of which the tilting door folded away down according to an embodiment of the invention can be. For example, the dishwasher may include a hinge unit, which allows a pivoting movement of the tilting door about two different, mutually offset pivot axes, of which - in the open horizontal position - is located in or at the edge of the dishwasher and the other for folding the door outside the Dishwasher is arranged.

According to an exemplary embodiment of the invention, the tilting door can be moved by means of the second bearing in a rotational and translatory manner between the open horizontal position and the folded-down position of the tilting door.

According to another exemplary embodiment of the invention, the door of the dishwasher is constructed multi-membered and preferably realized as a so-called lift-tilt door. As a result, the lower part of the loading opening can be closed by a tilting door and the upper part of the loading opening by a translatory, vertically movable door. In this case, the lifting door and tilting door can be connected to one another in terms of force transmission, so that, for example, an opening movement of the tilting door also causes an opening movement of the lifting door or vice versa.

According to a further aspect of the invention, a safety device can be provided in the dishwasher, which prevents the door from moving inadvertently, in particular when the tilt door is tilted down. The securing device can be designed such that the tilting door can only be moved around a single axis for closing and opening the dishwasher as long as a conventional tilting door, as the securing device is unactuated and can only be folded down when the securing device is operated to hold the lifting door is.

Compared to conventional dishwashers in which the cleaning access to the washing chamber is prevented by the open door, can be done by the folding of the tilting door according to the invention in a vertical position by the tipping door almost unhindered access to the washing chamber, so that even small people the interior completely view and access without difficulty. Thus, the time required to clean the rinsing chamber can be reduced and at the same time a more thorough cleaning of the rinsing chamber can be achieved.

According to an exemplary embodiment of the invention, a dishwasher, in particular a device dishwasher, with an opening for loading and unloading the Dishwasher with items to be washed and a particular multi-door for closing the opening proposed, wherein the door comprises at least one door leaf and at least one hinge device, preferably two hinge devices for movably connecting the door panel with the dishwasher. The at least one hinge device has a first bearing, which may be referred to as a tilting bearing, and which is adapted for moving the door leaf to a first position, in which the door leaf extends to cover the opening in the vertical direction, and to a second position, in the door leaf extends to release the opening in the horizontal direction. The first bearing may preferably be realized as a tilting bearing and in particular allow a pivoting movement of the door leaf about a first pivot axis. The extension direction of the door leaf may be defined relative to this first pivot axis. The first position can realize a closed position, in which preferably the opening for loading and unloading the dishwasher is covered by the door and optionally sealed by means of one or more seals between the door and the dishwasher sealing. The second position can be a loading and unloading position in which the dishwasher can be loaded with items to be washed, for example by means of a basket of equipment which can rest slidably on the opened door leaf.

Furthermore, the at least one hinge device has a second bearing which is designed to move the door leaf, in particular from the second position into a third position which releases the opening, in which the door leaf extends in the vertical direction. Preferably, the second bearing is a knockdown bearing that permits pivotal movement of the door leaf about a second axis such that the door leaf extends downwardly in a third position, which may be referred to as a cleaning position or a maintenance position, substantially vertically.

It is also conceivable that the second bearing is adapted for moving the door leaf from the first position into an opening releasing third or fourth position, which extends the door leaf in the vertical direction, in which case the movement of the door leaf pivoting about a vertical realized second pivot axis, so that the door leaf extends in the third or fourth position substantially laterally of the opening for loading and unloading the dishwasher.

By the door leaf is brought into a position releasing the opening in which the door leaf extends in the vertical direction and thereby the surface before the loading and unloading is completely or at least largely released by the door leaf, Users can freely approach the loading and unloading of the dishwasher from the door leaf to access the rinsing chamber. As a result, it is also possible for small people readily to see the entire interior of the washing chamber to make cleaning and / or maintenance.

In a further embodiment of the invention, the door next to the door leaf further comprises at least one further door member, such as a lifting, sliding, folding or roller shutter door member, which has a the opening of the dishwasher releasing and the opening of the dishwasher concealing position and which is coupled via a transmission with the door leaf such that a door leaf movement causes movement of the at least one further door member. In this way, the user must operate only one of the door members to open the dishwasher to open or close the dishwasher. In the first position of the door panel, the door panel and the at least one further door member completely cover the opening of the dishwasher together.

A multi-unit door can be formed, for example, as a lifting / tilting door, folding / tilting door, sliding / tilting door, folding / tilting door or with a tilting door leaf and a roller shutter-like door member. A multi-unit door panel allows providing a relatively large loading and unloading by means of several relatively small door members, so that their individual weight is much lower than the weight of a one-piece door to close a complete loading and unloading, which reduces both the mechanical load on the door hinges also simplifies the use.

The door may for example be designed so that in the first position of the door leaf, the weight of the at least one further door member counteracts an opening movement of the door leaf and acts in the second position of the door leaf, the weight of the door leaf against a closing movement of the door leaf. For this purpose, a transmission can amplify the respectively movement-inhibiting weight force, preferably in the first position of the door leaf, the weight of the at least one further door member and in the second position of the door leaf, the weight of the door leaf itself.

The transmission may provide, for example, by means of a lever mechanism and / or a cable transmission or the like in particular a power transmission function, such as a lever action, which depends on the position of the door leaf, that translates the weight of the door leaf or the at least one other door member, which is a persistence of Door leaf in the first (closed) position or the second (open) position conditionally, and the opposite weight force reduced, which could cause a movement of the door panel.

According to another exemplary embodiment of the invention, the dishwasher further comprises a securing device having a first securing unit for blocking or allowing movement of the door leaf by means of the first bearing, and a second securing unit for blocking movement of the door leaf by means of the second bearing permit. Preferably, the first securing unit can block a movement, in particular a tilting movement, of the door leaf from the second (loading or unloading) position into the first (closing) position and the second securing unit blocking a movement from the second (loading or unloading) Block the position to the third (folded down) position. The securing units of the securing device can be realized, for example, as a securing bolt or bolt and prevent unwanted movement of the door panel and possibly other door members to ensure that the user and the dishwasher will not be damaged, especially in lift and tilt doors.

In addition, the security device may comprise a bi-state actuation device that may be actuated to be in either a first or a second state. In the first state, the actuating means causes the first securing unit to block and the second securing unit to allow door leaf movement. In the second state, the actuating means causes the first securing unit to allow and the second securing unit to block a door leaf movement. In this way, in the blockage of the first or second bearing, the other bearing can be released by the actuating means, so that it is ensured that a movement of the door leaf always takes place only with the aid of one of the two bearings, ie either the first bearing or the second bearing. By means of the actuating means, which can switch between the two states, operating errors are avoided, which could occur if a movement of the door leaf were simultaneously possible by means of both bearings.

Further, when two or more hinge devices are used, for example, at both side edges of the door panel in the first horizontal direction, it is possible for both hinge devices to be equipped with actuating means as described above. The actuating means of the two or more hinge devices, in turn, can be operatively connected to each other such that all the actuating means are in the same of the two states are located. In this way it is ensured that a faulty operation of the safety device is almost impossible.

In addition, the securing device may further comprise a holding member, which provides a holding force acting on the actuating means, in particular a spring force, which is to overcome for switching between the first state and the second state of the actuating means. This ensures that the actuating means remains in the state set by the user and does not unintentionally permit one of the securing units to move the door leaf.

In a further exemplary embodiment of the invention, the hinge device has a carrier, which is held movably on the dishwasher by means of the first bearing, wherein the door leaf is held movably on the carrier by means of the second bearing. The carrier can therefore be arranged as a connecting member for transmitting power and for the movable connection between the door leaf and the dishwasher, so that the door leaf is connected indirectly by means of the carrier with the dishwasher.

Optionally, the carrier may comprise an elbow having two legs angularly offset from one another. The carrier may be in particular L-shaped, so that the legs of the angle are approximately at a right angle to each other or offset. The angle piece may also have a smaller angle than 90 ° between the legs, so that the angle piece could be referred to as V-shaped, or an angle greater than 90 °. The first leg of the elbow is connected to the door leaf and extends in the first position as well as in the second position of the door leaf substantially parallel to the door leaf, so the first leg extends in the first position of the door panel in the vertical direction and in the second position the door leaf substantially in the horizontal direction.

Further, the second leg of the elbow may include a stop which may, for example, be realized as a projection formed transversely to the two legs of the leg piece to make contact with the dishwasher in the second position of the door leaf. Preferably, the contact contact is realized in that the second leg is brought into contact with the inside of the dishwasher housing. In this way, it is ensured that in the open position of the door leaf, the door leaf does not need to come to rest on a support, so that signs of wear on the outside of the door panel are avoided.

Furthermore, a gear attack point for connecting the door leaf to the transmission for connection to the at least one further door member may be provided on the second leg of the elbow. The gear attack point is preferably arranged on the second leg such that, in the second (open) position of the door leaf, it is offset starting from a pivot axis of the first bearing in the direction of the rinsing chamber and is arranged vertically above the axis of the first bearing. Preferably, the second bearing and in particular the first bearing are arranged on the first leg of the angle piece.

In one embodiment of the invention, the door leaf can be movable by means of the second bearing rotationally and optionally translationally between the second position and the third position. In order to allow a rotational and in the second horizontal direction translational movement of the door leaf between the second position of the third position, the second bearing may comprise a slot with bolt guided therein. The slot may be provided on the carrier side, in particular on the first leg of the angle piece, or on the door leaf side.

Furthermore, the second bearing can comprise a groove and / or a rail for, in particular, translationally guiding a pin, preferably in the horizontal direction. Preferably, in the first leg of the angle piece, a groove is introduced, which is open in the horizontal position in the second position of the door leaf. Preferably, the rail horizontally extends in alignment with the lower side edge of the groove in the second position of the door leaf so that a door leaf side pin is slidably guidable out of the groove along the rail.

The slot, the bolt, the pin and the groove and / or the rail can be dimensioned such that for moving the door panel from the second position to the third position, the door leaf initially starting from the second position, a substantially translational movement in the horizontal direction must perform before the pin is released from the groove and / or the rail so that the door leaf is movable to the third position, ie preferably can be folded down. In this case, the bolt realized in the slot a second pivot axis for the door leaf. The bolt-slot pairing as well as the pin-groove / rail pairing each comprise a part which is fixedly arranged on the carrier, in particular on the first leg, and a second part which is fixedly arranged on the door leaf. That is, elongated hole and groove and / or rail can optionally be arranged on the support or arranged on the door leaf or the slot may be arranged on the carrier and groove and / or rail on the door leaf or the slot may be arranged on the door leaf and the groove and / or the rail on the carrier.

Preferably, the elongated hole has a latching point, such as a notch, for the bolt for pivoting the door leaf about the axis of the bolt, so that the pivoting of the door leaf always takes place about the same defined pivot axis and during the pivoting into the third position a translational movement is avoided.

In addition, the carrier may be stationary in the first state of the actuating means relative to the door leaf and be stationary in the second state of the actuating means relative to the dishwasher. For this purpose, the securing units of the securing device can each cooperate with a leg of the angle piece.

Furthermore, it is possible for the first securing unit to comprise a locking bolt which is preferably movable in the horizontal direction (x) in order to produce a preferably form-locking connection between the door leaf and the carrier and / or the door leaf and the dishwasher. In particular, the locking bolt is translatable parallel or coaxial with the first pivot axis and may preferably be arranged such that the locking bolt provides the axis about which the door leaf is pivotable between the first position and the second position. In this way, a particularly advantageous construction with few components can be realized, since the first pivot axis of the door leaf is realized in functional union with the second securing unit. The locking bolt preferably connects the housing of the dishwasher in particular form-fitting manner with the carrier and can also produce or release a positive connection with the door leaf.

In a further exemplary embodiment, the second securing unit can comprise a particularly pivotable latch for establishing a positive connection between the dishwasher and the carrier, in particular the second leg of the carrier, preferably the projection provided on the second leg of the carrier. This latch can be configured in an advantageous embodiment of the invention as an actuator for actuating the actuating means, so that as a result of producing the positive connection between the dishwasher and the carrier by means of the bolt, the positive connection between the door leaf and the Carrier and / or the housing of the dishwasher is released by means of the locking bolt.

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to the concept of a dishwasher, preferably for commercial use, in particular a device dishwasher. Advantageously, the dishwasher is equipped with a lift-tilt door, the tilting door member next to a vertical closed position and a horizontal loading and unloading position can take another position in which the door leaf of the tilting door extends in the vertical direction and the loading and unloading of the dishwasher and the area lying in front of said opening as far as possible or even completely free, so that a person can freely access the washing chamber of the dishwasher through the tilting door.

The dishwasher according to an embodiment of the invention comprises a hinge device with two bearings for moving the door leaf of the tilting door relative to the dishwasher, which each allow a pivoting movement and optionally a translational movement of the door leaf. Thus, it is possible to move the door leaf of the tilting door not only about a first axis in the vertical closed position and the horizontal loading and unloading, but the tilting door about a second (horizontal) axis down to the Abklapp-, cleaning or maintenance position bring. The movement of the door leaf into the maintenance position preferably takes place from the loading and unloading position.

Alternatively, the second axis may be vertically aligned in an alternative embodiment of the invention (not shown) such that the tilt door of the dishwasher is laterally retractable from the closed position to open the dishwasher and release the surface in front of the dishwasher. A lateral folding away the tilt door allows almost completely release the area in front of the loading opening of the dishwasher. In another alternative (not shown) embodiment of the invention, the tilting door can be moved so directly from the closed position into a vertical Abklappstellung the closed position that no horizontal intermediate position (i.e., in particular no loading and unloading position) must be taken.

The vertical direction (z) may be the direction in which gravity acts on the dishwasher. A first horizontal direction (x) can be defined by a first, relative to the dishwasher, that is in particular the housing and / or frame, fixed pivot axis of the tilting door. A second horizontal direction (y) extends transversely, in particular perpendicular, to the vertical direction (z) and transversely, in particular perpendicular, to the first horizontal direction (x). Furthermore, it is clear that directions with respect to the dishwasher and its components are to be understood within the scope of usual manufacturing tolerances.

The bearings can be realized in different ways to allow a movement of the door leaf relative to the dishwasher, so in particular their housing or frame. Preferably, a bearing is equipped with a ball bearing or sliding bearing so that a rotational mobility of at least the door leaf is made possible around an axis, wherein the axis can be realized by means of a round, rotationally symmetrical axis body. But it is also conceivable that a bearing is configured for example as a four-bar link, which does not require a pure rotational movement, but a mixed rotation and translation movement of at least the door panel. Stationary to the door leaf, other components of the tipping door, in particular parts of the hinge device, can move with the door leaf.

Optionally, the dishwasher may comprise a securing device provided with an actuating means capable of taking two different states. In the first state, the actuating means can cause the securing device to allow movement of the door leaf from the closed position into the loading and unloading position, but prevents further movement of the door leaf into the folded-down position. In the second state, the actuating means causes the securing device to allow the door leaf to be movable into the folded-down position, but to prevent any other unwanted movement of the door leaf and, thus, kinematically connected components. This is particularly advantageous if the door is constructed mehrgliedrig, such as lift-tilt door and the plurality of door members are connected in accordance with power transmission such that the movement of a door member has a movement of the other door member result. In such a power transmission connection of several door members, it may be provided, for example, that the weight of the door leaf of the tilting door in the open state of the tilting door from the weight and the lever arm, starting from the first pivot to the center of gravity of the door sheet torque applied to one or more other door members , in particular a lifting door member which is movable in translation in the vertical direction to hold in the open state against the weight thereof. When the door leaf is folded down, its center of gravity moves closer to the first pivot axis, so that the force caused by the weight of the door leaf torque is reduced, which may have the result that the Door leaf outgoing torque is insufficient to hold a lifting door member in its open, raised position so that it can close jerky and possibly the user, dishes or the dishwasher can affect.

The invention will be described in the following paragraphs primarily with reference to a device dishwasher designed for commercial use. However, the principles of this invention are not limited to the use of such a device dishwasher. For example, another commercial kitchen appliance, such as an oven, a combination damper, a refrigerator or the like with a door, as described in the present application, can be equipped.

A device washer according to an exemplary embodiment of the invention is shown in FIGS Figures 1-4 shown. The Figures 5-8 show detailed views of a dishwasher according to the exemplary embodiment of the invention according to the Figures 1-4 ,

The exemplary dishwasher 1 comprises in its lower region a frame 3 and in its upper region a rinsing chamber 5, which is arranged in a housing which is supported by the frame 3. The rinsing chamber 5 is substantially parallelepipedic and bounded on five of six sides by a housing wall. The sixth side of the rinsing chamber 5 forms an opening 6 for loading and unloading the dishwasher 1 and can be at least partially covered by an optionally mehrgliedrige door 7 for closing the opening 6.

In the frame 3 below the washing chamber 5 numerous (not shown) components of the dishwasher 1 can be accommodated for their supply of (hot) water and energy and their control.

The rinsing chamber 5 is in the Figures 1-4 Insofar shown only schematically, as components of the dishwasher 1, which are located within the washing chamber 5, such as screens, rinsing arms or the like, not shown, so that the door 7, the tilting door member 11, the lifting door member 13 and the guides or hinges for holding the door members 11, 13 are better visible on the dishwasher 1. The following details the door 7, its components and functions.

In the embodiment shown in the figures, the tilting door member 11 comprises a flat door leaf 21 for at least partially opening or closing the washing chamber 5. In the in FIG. 1 shown closed door position forms an inside 22 of the door leaf 21 a portion of a wall of the washing chamber 5. The other side or outside 23 of the door panel 21 forms part of the dishwasher housing.

Below the opening 6, a first pivot axis A1 is arranged near the lower front edge of the washing chamber 5 in the dishwasher 1, which extends in the horizontal direction x and the door leaf 21 of the tilting door member 11 may consist of the in FIG. 1 illustrated first position or closed position by a rotation about the first pivot axis A1 in the in FIG. 3 shown second position or loading and unloading be brought. In the loading and unloading position, the door leaf 21 extends from the first pivot axis A1 in the horizontal direction y away from the dishwasher 1. In this position, for example, a device basket can be placed on the inside 22 of the door panel 21 to insert cutlery, dishes or appliances, such as pots, pans, sheets or the like. The device basket can then be inserted by means of a horizontal translational movement through the opening 6 in the rinsing chamber 5. For this purpose, 5 carriers (not shown) are provided in the washing chamber, the surface of which are located substantially on the same horizontal plane as the inside 22 door leaf 21 in the loading and unloading position.

To actuate the tilting door member 11, this has a handle 25 which is arranged in the illustrated embodiment at the far end of the tilting pivot member A1 to the first pivot axis A1, so that the actuating force has the longest possible lever travel with respect to the first pivot axis A1. In another embodiment (not shown), the handle can also be arranged closer to the first pivot axis A1.

FIG. 2 shows a slightly open intermediate position in which the tilting door member 11 between the closed position ( FIG. 1 ) and the loading and unloading position ( FIG. 3 ) is located.

The Hubtürglied 13 can also from the closed position according to FIG. 1 in which an inner side 32 forms part of a side surface for defining the rinsing chamber 5 and thus partially closes the opening 6 of the dishwasher 1, in an open position according to FIG FIG. 3 to be brought. However, the opening movement of the Hubtürglieds 13 takes place in contrast to the movement of the tilting door member 11 as a translational vertical movement upwards.

Like from the Figures 1-3 it can be seen, the tilting door member 11 and the lifting door member 13 via a lever gear or coupling gear 41 are connected to each other force transmission, so that due to the rotational opening movement of the door panel 21 about the first pivot axis A1, a translational movement of the Hubtürglieds 13 is perpendicular upwards. The lever mechanism 41 comprises a relative to the door leaf 21 fixed lever arm 43, which extends from the first pivot axis A1, starting in the dishwasher, and a connecting rod 45, which is hinged to the remote from the first pivot axis A1 end of the lever arm 43 and whose end opposite the lever arm 43 is articulated on the lifting door member 13.

The lever mechanism 41 causes in the closed tilting and lifting door member position according to FIG. 1 in that the weight force of the lifting door member 13 acts on the lever arm 43 via the connecting rod 45, the almost entire length of which extends in the horizontal direction y from the pivot axes A1. In contrast, the weight of the tilting door member 21 acts almost without lever about the pivot axis A1, so that the weight of the lifting door member 13 in the closed position of the dishwasher 1 is increased by the lever mechanism 41 for keeping closed the dishwasher 1.

In the open state of the dishwasher according to FIG. 3 extends the lever on 43 as well as the connecting rod 45, starting from the first pivot axis A1 almost vertically upwards to the lifting door member 13, so that its weight almost without leverage the weight of the tilting door member 11 is opposite, whose center of gravity now at a relatively large distance to the first pivot axis A1 is arranged. In this way, by the lever mechanism 41 in the open state, the weight of the tilting door member 11 is increased for the open holding the door 7.

FIG. 4 shows the door panel 21 in a third position, which may be referred to as Abklappstellung, maintenance position, or cleaning position in which the door leaf 21, the opening 6 of the washing chamber 5 of the dishwasher 1 releasing and starting from the second pivot axis A2 (or starting from the first pivot axis A1) extends substantially vertically downwards. The door leaf 21 is for this purpose around the second pivot axis A2 from the open position according to FIG. 3 worked away down. The folding of the door panel 21 by means of a hinge device 51, which will be described below with reference to the detailed representations according to the Figures 5-8 is explained.

FIG. 5 shows in detail the tilting door member 11 in the horizontal loading and unloading position and the hinge device 51, which holds the tilting door member 11 on the (not shown) dishwasher pivotally. The horizontal direction x, in which the first pivot axis A1 extends, is perpendicular to the plane of the FIGS. 5 and 6 oriented. In the exemplary embodiment, the hinge device 51 has an L-shaped angle 53, which comprises a door leg 55 and a lever leg 43, which realize the L-shape, wherein in the closed position of the tilt-door member 11 (FIG. FIG. 1 ) the door leg 55 extends parallel to the door leaf 21 of the tilting door in the vertical direction z and the lever arm or lever arm 43 extends perpendicular to the door leaf 21 in the horizontal direction y in the washing chamber 5 inside.

In another, not shown embodiment, the legs of the angle piece 53 may be arranged at a different angle to each other, as in the FIGS. 5 and 6 shown right angle. On the door leg 55, both components of the first bearing are arranged, which allows the pivoting movement of the door panel 21 about the first pivot axis A1, as well as part of the second bearing, which pivotal movement and a translational movement of the door panel 21 from the loading and unloading position in the FIG. 4 illustrated Abklappstellung allowed. In the Abklappstellung according to FIG. 4 a majority, ie more than half, preferably more than ¾, of the door leaf extends downwardly from the bottom edge of the opening 6 of the dishwasher. It depends in the exemplary embodiment according to FIG. 4 the tilting door member 11 at the second bearing of the hinge device 51, and extending from the second pivot axis A2 and starting in the vertical direction z down.

In the in the Figures 1-8 illustrated embodiment of a dishwasher 1 according to the invention, the tilting door member 11 is held by two hinge devices 51 at two opposite sides of the door panel 21 in the horizontal direction of the dishwasher 1. But it is also conceivable that more than two hinge devices 51 are provided for supporting the door panel 21, which may be advantageous if the tilting door member 11 is particularly large and heavy.

The angle piece 53 has a tip 54, from which extend the two legs 55, 43 offset in the illustrated embodiment about 90 ° to each other. The orientation of the door leg 55 and the lever arm 43 will be described below with reference to the in the Figures 3 . 5 and 8th illustrated loading and unloading of the tilting door member 11. It is clear that the tilting door member 11 and the hinge device 51 in other Positions of the door, for example, according to the Figures 1 and 2 , have a different orientation with respect to the coordinate system, in which the vertical direction z is defined by the effective direction of gravity on the operated dishwasher 1. Furthermore, in the coordinate system, a first horizontal direction can be defined by the lower edge of the opening 6 of the dishwasher 1 or the first pivot axis A1 and the second horizontal direction y can extend transversely, preferably perpendicular, to the plane of the opening 6 of the dishwasher 1.

The hinge device 51 has in the door leg 55 a circular cross-section opening or receptacle 57 in which a fixedly arranged on the dishwasher axis body (not shown) may be arranged to realize a pivotal mounting about the first pivot axis A1, along the bottom edge of the opening 6 extends. Such a first bearing can be realized for example as a sliding or ball bearings. Further, it is clear that a kinematically inverted bearing may also be suitable for a pivotal mounting about the first pivot axis A1, in which the axle body is fixedly mounted on the angle piece 53 and the corresponding receptacle is fixed to the dishwasher.

Furthermore, the door leg 55 has a slot 61 extending in the horizontal direction y, in which a bolt 63 stationary on the door leaf 21 of the tilting door member 11 can be guided so that the bolt 63 can make a translational movement in the slot 61 in the horizontal direction y. The bolt 63 is preferably a round bolt, so that by means of the bolt 63, a rotational movement of the door leaf 21 about the pivot axes of the bolt 63 in the slot 61 can be completed. Preferably, the elongated hole 61 has, at its end remote from the dishwasher 1 or first pivot axis A1, a notch 64 in which the bolt 63 can sit in order to provide a defined position of the second pivot axis A2 for the pivoting movement of the door leaf 21 in its folded-down position, in such a way that when pivoting the door leaf 21, an undesirable translational movement of the bolt 63 in the slot 61 is avoided.

Furthermore, a groove 65 which is open in the horizontal direction y and has an upper and a lower groove wall or wall is provided on the tip 54 of the angle piece 53 of the door leg 55, the lower groove wall starting from the groove base being substantially longer than the upper wall , whereby a rail 67 is formed, which, starting from the groove base in the horizontal direction of the dishwasher or first Swivel axis A1 extends away. In the groove 65 and on the rail 67 a fixedly arranged on the door leaf 21 pin 69 can be performed.

Preferably, the elongated hole 61 and the groove 65 are dimensioned with the rail 67 such that the groove 65 and elongated hole 67 extend in substantially the same direction, wherein the effective longitudinal extension of the groove 65 and the rail 67 is shorter than the effective longitudinal extension of the slot 61 In this way, a translational movement of the door leaf out of the loading and unloading position away from the dishwasher or the first pivot axis A1 can take place such that the path of movement of the door member 21 with the bolt 63 fastened thereto is limited by the effective longitudinal extent of the slot 61. The length of the lower groove wall or the rail 67 is shorter than the movement path of the bolt 63, so that the pin 69 is released due to the translational movement of the guide through the groove 75 and the rail 67 so that the door leaf 21 from the stationary connection the angle piece 53 of the hinge device 51 is released to be pivotable by means of the second pivot bearing about the second pivot axis A2 in the Abklappstellung. The released pin 69 is in FIG. 6 to recognize, in which the door leaf 21 is shown in an intermediate position at the beginning of the Abklappbewegung.

The bolt 63 and optionally the pin 69 may have a front guide stopper, such as a circlip or a head plate whose dimensions, in particular diameter, are greater than the width of the slot 61 and the groove 65 transversely to the respective direction of longitudinal extension, so that the guide stopper tilting of the door leaf 21 prevented.

The kinematics of the second bearing can in principle be realized by a plurality of different concrete embodiments, which is why the dargestell preferred in the figures embodiment is not to be understood as a limitation of the invention. For example, the slot, the groove 65 or both could be arranged fixed to the door leaf 21 and the pin 63 and the pin 69 correspondingly fixed to the elbow 53. Instead of a groove 65, the lower inner wall extending in the horizontal direction beyond the upper inner wall and a Rail 67 forms, the groove can also be equipped with two equal inner walls. The illustrated embodiment with the rail 67 has the advantage that when folding the door leaf 21 from the Abklappstellung ( FIG. 4 ) in the loading and unloading position ( FIG. 3 ) the pin 69 first on the rail 67th can be stored so that the user no longer has to carry the weight of the door panel 21 while threading the pin 69 in the groove 65.

Instead of a guide by means of a bolt in a slot and a pin in a groove, a mixed translational and rotational movement of the door panel 21 from the loading and unloading in the Abklappstellung for example, by a second bearing in the form of a four-bar linkage (not shown) be realized. However, the illustrated preferred embodiment with the bolt 63 and the pin 69 is advantageous in that few moving parts are used, making the bearing very insensitive to operator error and wear.

The lever arm 43 does not extend directly upward starting from the first pivot axis A1, but is arranged in the horizontal direction y in the direction of the dishwasher 1 or its rinsing chamber 5 offset from the first pivot axis A1. At the end of the lever arm 43 distal to the first pivot axis A1, a stopper 44 is arranged, which can be realized, for example, by a folded-over part of the angle piece 53, which extends substantially in the horizontal direction x, in order to be brought into holding engagement with the dishwasher 1 become.

Also on the first pivot axis A1 distal end of the lifting leg 43, a nose 46 may be provided for a pivot point of a connecting rod 45, a cable or the like, as part of a power transmission coupling 41 between the tilting door member 11 and the door member (not shown). The nose 46 with the articulation point for the connecting rod 45 may be offset relative to the first pivot axis A1 in the horizontal direction y in the direction of the washing chamber 5 and in the vertical direction upward to ensure that with respect to the first pivot axis A1 always a minimal lever path between the force application point or articulation point is ensured for the weight of the lifting door member 13 in the lever arm 43.

The FIGS. 7 and 8th show a perspective detail view of a hinge device 51, wherein FIG. 8 is an exploded view. As in the previous ones FIGS. 5 and 6 is also in the FIGS. 7 and 8th the dishwasher, moreover, not shown.

In the exemplary Embodiment of the invention causes the securing device 71, that the door leaf 21 can move either by means of the first bearing or by means of the second bearing, and excludes a movement of the door leaf simultaneously by means of the first and the second bearing.

For this purpose, the securing device 71 comprises a securing latch 73, which is mounted on the dishwasher 1 (not shown) so as to be movable relative to the dishwasher 1 with a stationary latch pivot axis R. In the in FIG. 7 As explained above, the lever leg 43 of the angle 53 is at the same time by means of the stopper 44 in a touching contact with the dishwasher 1. Thus, a pivoting movement of the elbow 43rd blocked by the first pivot axis A1 in a first direction by the contact contact of the stopper 44 and dishwasher 1, while a pivoting movement of the angle 53 is blocked around the first pivot axis A1 in an opposite second direction by the contact of the locking bolt 73 with the lever arm 43. A movement of the angle piece 53 and the associated tilting door 11 by means of the first bearing about the first pivot axis A1 can not take place. Since the (not shown) Hubtürglied is already coupled via the connecting rod 45 power transmission with the elbow 53, and the Hubtürglied can not complete any movement, while the locking latch 73, the angle piece 43 fixed to the dishwasher 1.

In the exploded view according to FIG. 8 the safety catch 73 is in a vertical position, in which it releases a movement of the angle piece 53 by means of the first bearing about the first pivot axis A1.

Furthermore, the securing device 71 for the purpose of adjustability of the permissible movement of the door leaf comprises a securing bolt 75 which can be positively or at least frictionally engaged with a receptacle 77 which is fixedly provided on the door leaf 21 to a relative movement between the door leaf 21 and the elbow 53 to prevent. This securing bolt 75 is intended to force a joint pivoting movement of the door leaf 21 with the angle piece 53 by means of the first bearing about the first pivot axis A1. The securing bolt 75 can be removed in translation from the door leaf-side securing receptacle 77 in order to allow a relative movement of the door leaf 21 relative to the angle piece 53 by means of the second bearing. In the embodiment according to the figures, the second bearing is as above described realized by the guided in the slot 61 bolt 63 and guided by means of groove 65 and rail 67 pin 69. In the exemplary embodiment according to FIG. 8 The safety bolt 75 can also realize the axis body of the first bearing in a functional union, so that the number of components is reduced.

In another embodiment according to FIG. 9 the sleeve 78 realizes the axle body of the first bearing. The sleeve 78 can be welded onto the angle 53. The sleeve can protrude into a corresponding opening of the dishwasher housing.

The locking bolt 75 is arranged translationally in a pin bearing 76 fixedly attached to the dishwasher. The translational travel of the locking bolt 75 is in accordance with the exemplary embodiment FIG. 8 coaxial with the first pivot axis A1. In the embodiment of the FIG. 8 realized recording 77 together with the locking pin 75 is a sliding pivot bearing for the door leaf 21. In the embodiment of the FIG. 9 realized the sleeve 78 together with the pin bearing 76, the sliding pivot bearing for the door leaf 21. The maximum translational movement of the locking bolt 75 is dimensioned in both embodiments such that the engagement with the receptacle 77 can be solved, but the angle always held on the dishwasher housing or at least secured. For this purpose, the locking pin 75 can continue to extend through a recess 57 in the bracket 53 so that it is always held by the locking pin 75 or at least secured. Alternatively, the sleeve 78 of the angle piece 53 always protrude into a corresponding housing-side receptacle.

In a further alternative embodiment (not shown) of a dishwasher, a further, secondary securing unit can be provided which, due to a translational movement of the door leaf, conceals the recess in the angle piece 53 in such a way that the securing bolt 75 does not come out of the in FIG. 7 shown position can be moved as long as the receptacle 77 is not coaxial with the axis of the locking or locking bolt 75. By an operative connection with the securing bolt 73, it can further be ensured that the securing bolt 73 does not change when the door leaf 21 is hinged or folded down.

In another alternative embodiment (not shown), a locking member may be used to hold the door panel 21 stationary with respect to the first bearing be realized with respect to the hinge device 51 by means of a locking member which is not fixed with respect to the second pivot axis A2 on the dishwasher but only fixed to the hinge device 51, in particular the angle 53 is provided.

In the embodiment of the FIGS. 7 and 8th are the locking bar 73 and the securing bolt 75 by means of a Betätigungskopplung 81 movement connected according to each other in such a way that a release of the first (latch) fuse causes a locking of the second (bolt) fuse, so always only a movement of the door panel 21 using the first warehouse or second warehouse.

For example, relative to the locking bolt 73 a stationary about the latch axis R pivotable actuating lever 83 may be provided which engages, for example via a pin-slot connection in an actuating arm 85 which is pivotable about a fixed to the dishwasher 1 actuating axis B. At the opposite end of the actuating lever 83 to the actuating arm 85, the translationally movable locking bolt 75 is articulated. Thus, the locking latch 73 between the in FIG. 7 position shown and in FIG. 8 and FIG. 9 pivoted back and forth position to a movement of the elbow 53 by means of the first bearing about the first pivot axis A1 according to FIG. 8 to allow or according to FIG. 7 to prevent.

By the movement of the locking bolt 73, the translational movement of the securing bolt 75 is effected by means of the actuating coupling 81, so that the securing bolt in the position according to FIG. 7 allows movement of the door panel 21 by means of the second bearing and in the position according to FIG. 8 or FIG. 9 prevents a relative movement of the door panel 21 to the bracket 53, so blocked the second camp.

The operating lever 83 may be engaged with a retaining spring 87, so that a spring force, here a bending spring force, the retaining spring 87 when pivoting the locking bolt 73 and the associated operating lever 83 must be overcome in order to avoid unintentional change in the state of the securing device 71.

As an alternative to the embodiments of the invention shown by way of example, the individual securing members, for example the securing bolt 75 or the securing bolt 73, may be replaced by other securing members having the same function The individual securing members also need not be connected to one another by means of an actuating coupling 81 and can be individually locked or unlocked by a user, in which case, however, a specific sequence of actuation must be taken into account , so that no unwanted movement of the door panel 21 takes place. Alternatively, it is also conceivable that not only the fuse units of a securing device 71 of a hinge device 51 are operatively connected to one another by an actuating coupling 81, but rather several or even all safety devices of a door 7 of the dishwasher 1.

The function of the locking bolt 73, namely preventing movement of the door leaf by means of the first bearing, can also be realized by a (not shown) securing unit, which acts not on the hinge device 51 of the door leaf, but the lifting door member 13, provided the tilting door member 11 and the door member 13 are coupled to each other in terms of force transmission.

In the presently illustrated embodiment of a dishwasher 1 according to the invention, the securing bolt 73 serves to actuate the securing device 71 and is arranged within the washing chamber 5. Alternatively, it is conceivable to attach an operating unit, such as a knob, a lever or the like, to the outside of the dishwasher 1 to change the state of the securing device 71. In this way it is avoided that the condition of the securing device 71 is inadvertently changed during the cleaning access to the rinsing chamber 5 by the user.
