Abstract

The overall door (GT) of a household dishwasher (GT) according to the invention has an upper door part (OT), which is mounted so that it can be pivoted open to the front and bottom relative to its lower door part (UT) about a horizontal axis (DAO) in such a way that it is in the vertical closed end position of the Overall door (GT) when the upper door part (OT) is closed, viewed with a lower wall section (URA), an upper wall section (ORA) of the lower door part (UT) facing the washing area (SR) of the washing compartment (SB) of the domestic dishwasher (GS) on the wash room side overlaps with the formation of an overlap zone (UZ) and thus delimits the washing area (SR) on a partial section (UL) whose height extension (H), and that in its open positions the upper end face (OST) of the lower door part (UT) into the washing area ( SR) protruding into it. In addition to or independently of the overlap zone (ZU), a movement gap (SP) with a slope into the washing area (SR) of the washing compartment (SB) can be provided between the upper door part (OT) and the lower door part (UT) when viewed from the outside to the inside .

Description

The invention relates to a domestic dishwasher with a washing container, the front loading opening of which can be closed by an overall door which is mounted so that it can be swung open about a lower horizontal axis forwards and downwards, the overall door comprising an upper door part and a lower door part, and the upper door part opposite the lower door part is mounted so that it can be swung open about a horizontal axis forwards and downwards,

In the case of the overall door designed primarily for an oven DE 10 2009 002 276 A1 a first, upper door unit is mounted rotatably about a horizontal axis on a second, lower door unit. The first door unit and the second door unit can be coupled to one another by means of a coupling unit in such a way that in the closed end position of the entire door with a vertical closed end position of the upper door part, the lower end of the upper door unit and the upper end of the lower door unit viewed in a vertical longitudinal section with an approximately straight line in Movement gap running in the depth direction are largely flush with one another. The coupling unit comprises a receptacle which is housed in a fixed manner in the space between the front plate and the inner wall of the lower door unit facing the cooking space of the oven. A swivel arm is inserted into this receptacle, which protrudes upwards into the interior space between the front panel and the inner wall of the upper door unit from its lower end face. It is connected to a tension spring via an intermediate piece, which is attached to the top of the upper door unit. The hinge arm has a projection which extends to the front, front end of the approximately horizontally extending movement gap. In the front end of the projection, which lies in the gap between the front panel of the upper door unit and the front panel of the lower door unit and largely fills it, a recess is provided in which a cylindrical, first axis of the first door unit is mounted. The swivel arm also has a joint with a second axis, which is arranged offset in the movement gap with respect to the first axis inwardly into the interior of the entire door. By means of the joint, the intermediate piece is mounted rotatably relative to the hinge arm about the second axis, which is parallel to the first axis and is arranged further back than the first axis with respect to a direction of view of the front surface when the door units are closed.

This construction of an overall door, which has an upper flap door, cannot easily be transferred to a household dishwasher, since it has minimum requirements, such as liquid and / or vapor tightness and / or cleanliness, during the course of a dishwasher program.

In the EP 2 596 736 A1 is among others in the 18th , 19th specified a dishwasher with a divisible door, the upper door half of the lower door half by means of a hinge can be folded away forwards and downwards. The joint is provided in the middle of the horizontal movement gap between the lower front edge of the upper door half and the upper front edge of the lower door half.

In the WO 2015/190713 is in the 36 Among other things, a dishwasher with a divisible door is shown, in which an upper door part is rotatably mounted in its closed end position with its lower end face having a stepped profile at a gap distance flush with the upper end edge of a lower door part having a complementary profile. This results in a continuous gap with a gradient from the inside to the outside between the facing edges of the upper door part and the lower door part.

The invention is based on the object of providing a household dishwasher with an overall door that can be swung open about a lower horizontal axis forwards and downwards, in which an upper door part is additionally mounted so that it can be swung open about a horizontal axis compared to a lower door part and yet in use there are requirements, such as for its Leak tightness, ease of cleaning, susceptibility to soiling, manageability, operability, ergonomics, etc ..., as with a conventional, one-piece standard door are sufficiently fulfilled. With use is meant in particular on the one hand the washing operation of the dishwasher with washing liquid in one or more liquid-carrying partial wash cycles and a final drying cycle when executing a dishwashing program, on the other hand in particular the opening of the entire door and / or the upper door part for loading and / or Unloading of wash ware including the loading and / or unloading process itself, as well as closing or closing the entire door and / or the upper part of the door.

This object of the invention is achieved by a household dishwasher having the features of claim 1 and / or the features of claim 2.

In the context of the invention, information with spatial reference such as front, back, lateral, top, bottom, etc ... are to be understood from the point of view of a user who is in front of the Household dishwasher is standing and its washing container looks in the depth direction.

The washing compartment of the household dishwasher according to the invention has a front loading opening which can be closed by an overall door which is mounted as a whole so that it can be swung open about a lower horizontal axis forwards and downwards. The entire door comprises an upper door part and a lower door part. In addition, the upper door part can be swiveled open on its own, i.e. separately around a horizontal axis, forwards and downwards compared to the lower door part. It is pivoted open in such a way that in the vertical closed end position of the entire door when the upper door part is closed, it overlaps with a lower wall section an upper wall section of the lower door part facing the washing area of the washing compartment on the wash room side to form an overlap zone and thus the wash room on a partial section its height extension is limited, and that in its open positions it protrudes over the upper end face of the lower door part into the washing area.

The upper door part can therefore preferably be pivoted open separately, i.e. individually with respect to the lower door part. Its axis of rotation assigned to it is in particular higher than the axis of rotation of the entire door.

Because in the vertical closed end position of the entire door with the upper door part closed, the upper door part with a lower wall section overlaps an upper wall section of the lower door part facing the washing area of the washing compartment on the washing area side to form an overlap zone and thus delimiting the height of the washing area on a partial section, is during the washing operation of a running dishwashing program in which washing liquid is distributed, in particular sprayed, in the washing area of the washing container onto one or more receiving units such as crockery baskets and / or a cutlery drawer by means of one or more liquid distribution devices, in particular spraying devices such as rotatable spray arms, is largely ensured that a movement gap between the upper wall section of the lower door part and the lower wall section of the upper door part is covered on the wash room side. Thus, liquid spray jets from the one or more liquid distribution devices, in particular spray devices such as a lower and / or an upper rotating spray arm, cannot hit the movement gap directly. The fact that a lower wall section of the upper door part is extended downwards by an overlap section over the height extension of the movement gap between the two opposing end faces of the upper door part and the lower door part, an overlap zone on the washroom side is formed which acts as a first barrier against Liquid entry into the movement gap acts. Thus, the tightness of the entire door against the escape of liquid and / or steam on its front side facing a user is improved in the area in which the lower wall section or lower edge of the upper door part pivoted open and the upper wall section or upper edge of the opposite preferably with a vertical extension stationary, in particular securable, preferably lockable, lower door part with the movement gap opposite one another. The overlap zone also counteracts contamination of the movement gap between the upper door part and the lower door part with dirt particles, such as food residues, which are washed off the items to be cleaned during the washing operation by spray jets from one or more spray devices such as rotatable spray arms. When the upper door part and the lower door part are coupled to one another to form the entire door, in particular connected, and the entire door is pivoted into an open position, in particular into its approximately horizontal end position, the overlapping section of the upper door part that then comes to lie on top covers the one facing it below the edge section of the lower door part coming to lie on it so that falling liquid droplets and / or dirt particles are kept from the movement gap between the facing end faces of the upper and lower door parts at least from above.

In addition, since the upper door part in its open positions up to and including its approximately horizontal end position protrudes over the upper face of the lower door part into the washing compartment SB, that is, protrudes into the washing compartment SB opposite the upper face of the lower door part, which is preferably left standing vertically, it covers from above the movement gap between the upper door part and the lower door part, in particular the upper end face of the lower door part, which preferably remains standing vertically, like a roof. In all open positions, in particular in the horizontal opening end position, of the upper door part, its upper side, ie its inner door wall on the wash-room side, is higher than the upper face of the lower door part. Through this roofing, the movement gap between the upper door part and the lower door part, in particular the upper end face of the lower door part, is at least preventively protected from liquid droplets and / or dirt particles falling from above. In the approximately horizontal open end position of the upper door part, the wall section facing the lower door part overhangs the upper end face of the lower door part from the front or outside, in particular at least as far as its inner edge on the wash compartment side. If, after the end of a dishwashing program, the upper part of the door is swiveled open and, for example, the upper crockery basket and / or the upper cutlery drawer is moved out of the washing container, it can happen that residual liquids that have collected in depressions in items to be washed flow down or drip off and on the upper side of the pivoted-open, upper door part, formed by the inner door wall on the washroom side, strike. If the upper door part is pivoted into an open position, in particular into its horizontal opening end position, and the upper crockery basket and / or a cutlery drawer is moved out through the cutout of the loading opening that is then released and items to be cleaned such as dishes, glasses, cups, cutlery, etc. . placed in the upper crockery basket and / or the cutlery drawer, it can happen that liquids and / or dirt particles, such as leftovers, fall down from the washware items onto the top of the upper door part formed by the inner door wall on the washroom side. The roof then largely ensures that these liquids and / or dirt particles falling from above are kept from directly penetrating the movement gap between the upper door part and the lower door part. In particular, the upper end face of the lower door part, which preferably remains stationary in the vertical direction, remains sufficiently dry and / or clean.

In summary, the overlap zone in the closed end position of the upper door part or the cantilever zone in every open position, especially in the approximately horizontal open end position, of the upper door part ensures that the movement gap between the upper door part and the lower door part is not directly exposed to liquids and / or dirt particles is applied, but remains largely free of them preventively. In every position of the pivotable upper door part, the door arrangement according to the invention remains sufficiently insusceptible to soiling and / or liquid leaks. Despite the upper hinged flap door, the overlap zone or overhang zone largely avoids increased susceptibility to soiling in the movement gap between the upper door part and the lower door part. Rather, the overlap zone or protrusion zone provides sufficient ease of cleaning in all intended positions, i.e. in the closed end position and in the open positions of the upper door part. In the vertical closed end position with the vertical closed end position of the upper door part, when the domestic dishwasher is in operation, the overlapping wall section of the upper door part on the wash compartment side can be washed clean by spray jets from one or more liquid distribution devices, in particular spray devices, preferably by spray jets from a lower rotatable spray arm. In particular, the gap section located in front of a seal in the movement gap between the overlapping section of the upper door part and the wall section of the lower door part that is overlapped by it can also be sprayed by one or more liquid distribution devices, in particular spray devices, preferably by spray jets of a lower one, located in the washing chamber of the washing container rotatable spray arm, can be washed clean. In addition, liquids and / or dirt particles that come to lie on the top of the upper door part, for example when loading dirty wash ware, are removed when the upper door part is closed due to the increasingly inclined position of the upper door part up to its vertical closed end position over the overlapping wall section of the The upper door part is conveyed or tipped into the washing compartment of the washing compartment like a slide. Laborious cleaning of the narrow movement gap between the upper door part and in the lower door part by hand by the respective user can thus be largely avoided. If the two door parts are coupled to one another, in particular connected, to form the entire door, and the entire door is pivoted open into an open position, in particular into its approximately horizontal end position, the overlap section of the upper door part, which then comes to lie on the top, naturally covers the overlap section of the upper door part facing it to lie under it coming edge portion of the lower door part so that falling liquid droplets and / or dirt particles are kept from the movement gap between the facing end faces of the upper and lower door part at least from above.

Without the inventive washroom-side overlap zone or cantilever zone, however, if the upper half of the door is opened to load dirty items into an upper crockery basket, which is housed in the upper washroom area of the dishwasher's washing compartment, the movement gap or a gap in this - e.g. as in the EP 2 596 736 A1 - arranged joint freely accessible from above, ie visible from above, so that liquid and / or dirt that drips or falls into the upper crockery basket when loading dirty items such as dishes, into the movement gap and onto the Joint would arrive. This could possibly impair its function. In addition, they could be in the movement gap Any liquid and / or dirt particles that have reached the front end appear, flow out if necessary and run down the front or front of the lower door half. The cleaning of the movement gap, of the joint possibly arranged in this, and / or the front side of the lower door half can be too complex and / or too laborious in practice. In addition, a dirty and / or wet appearance of the movement gap visible from above and of the joint possibly arranged in it can displease the aesthetic perception of a user.

Furthermore, the overlap zone or the overhang zone of the door arrangement according to the invention also ensures that a user does not put his fingers into the narrow movement gap between when opening and / or closing the upper door part and in its respective open position, in particular in the approximately horizontal end position the upper door part and the lower door part can engage directly. In this way, the risk of injuries to body parts such as the fingers of a hand, in particular due to their trapping, is largely avoided. The lower edge section of the upper door part, which in the closed end position of the upper door part overlaps an upper wall section of the lower door part on the sink side or in the respective open position between its vertical closed end position and its horizontal open end position, including this horizontal open end position, the upper end of the lower door part protrudes into the wash chamber protrudes over or overhangs, ie protrudes into the wash cabinet opposite this upper end face of the lower door part, thus forms a mechanical protection against tampering on that side of the upper door part which is in the vertical closed end position of the upper door part in the wet area of the wash cabinet of the washing container and which is opened when opening of the upper door part comes to lie facing the respective user on the top.

It is only through this overlap section or overhang section with which the upper door part overlaps or overhangs an edge section of the lower door part facing it on the wash-room side that the door arrangement according to the invention with the separately pivotable upper door part and the lower door part becomes practical.

If, within the scope of the invention, reference is made to a section of the upper door part or the lower door part that delimits or closes the front loading opening of the washing compartment, the wall section on the wash room side, in particular the inner door wall section, of the upper door part or the lower door part, is meant in the vertical closed end position of the entire door during the washing operation of a running dishwashing program of the household dishwasher with liquid applied, ie can become wet. If the two door parts are connected to one another to form the overall door and if this closes the front loading opening of the washing compartment in its vertical closed end position, then its two vertically superimposed wall sections on the washroom side are preferably enclosed as a whole by a circumferential door seal attached to the inside of the front edge area of the washing compartment. Wall sections of the upper door part and / or the lower door part, which go beyond this defined boundary surface on the washing room side, ie are outside the boundary surface of the washing container side or viewed from the front, outside the boundary surface of the front loading opening of the washing container, are given dimensions and proportions of the height extension, overlap, and / or overhang of the two door parts not taken into account.

According to an advantageous development of the invention, it can be expedient if, in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, a lower wall section, in particular the inner door wall, of the upper door part and the upper wall section of the lower door part in the overlap zone on a height section between 2 , 5% and 50%, in particular between 5% and 25%, of the height extension of the section of the lower door part that delimits or closes the front loading opening of the washing compartment overlaps on the wash-room side. At a Dishwasher with the usual dimensions of its washing container (viewed without base support or without a base), the front loading opening of which has a clear height of about 65 cm, for example, and a lower door part that has a section of, for example, about 24 cm - 26 cm in height ( measured on the washing room side in its vertical position) closes or limited, the overlap zone has a height extension on the washing room side, delimiting the loading opening, preferably between 0.6 cm and 12 cm, in particular between 1.2 cm and 6 cm.

It can be particularly favorable if in the approximately horizontal end position of the upper door part of the wall section facing the lower door part the inner edge of the upper end face, ie the rear upper edge of the upper end face of the lower door part (viewed in its vertical position) with a protrusion length of at least 1 , 4%, in particular between 2.5% and 25%, of the vertical height on the washing area side of the section of the upper door part delimiting the front loading opening and protruding into the washing area. In a dishwasher with the usual dimensions of its washing container such as 65 cm clear internal height or height of the front-side limiting opening and a lower door part which closes or closes the loading opening with a section of, for example, about 24 cm - 26 cm in height (measured on the washing room side in its vertical position) . Limited, it can be beneficial in practice if the upper door part in its approximately horizontal end position of the washroom side or the rear upper edge of the lower door part with a projection length of at least 0.5 cm, in particular between 1 cm and 10 cm, in overhangs the wash cabinet.

The shorter the cantilever length selected, the greater the length (viewed in the depth direction) with which the upper door part in its approximately horizontal end position to overlap the upper crockery basket moved out of the washing container via it and / or one above or below this Cutlery drawer is available. In other words, the longer the section of the upper door part protruding from the washing container, in particular from its loading opening, in the approximately horizontal end position of the upper door part, the further the upper crockery basket and / or the cutlery drawer can be moved out of the washing area and to overlap or cover with the top of the upper door part. This facilitates free access from above to the upper crockery basket and / or the cutlery drawer. At the same time, the upper side of the section of the upper door part protruding freely from the loading opening of the washing container forms a drip protection or a catching device for liquid and / or dirt particles that come from above from the upper crockery basket and / or the cutlery drawer or from items to be placed in or removed from them falling down. Additional drip protection, e.g. in the form of a tub that can be moved out of the wash cabinet with the upper crockery basket, is not required.

In addition or independently of the above-explained overlap on the washroom side of an upper wall section of the lower door part and / or washroom-side overhang of the upper end face of the lower door part by a lower wall section of the upper door part, the object of the invention is achieved by a household dishwasher according to the invention, in which the front loading opening of the Rinsing container can be closed by an overall door which is mounted so that it can be pivoted forwards and downwards about a lower, horizontal axis, the overall door comprising an upper door part and a lower door part, and the upper door part relative to the lower door part about a horizontal axis forwards and forwards is mounted at the bottom so that it can be swiveled open such that between the upper door part and the lower door part, viewed from the outside to the inside, a movement gap is provided with a gradient into the washing area of the washing compartment.

In particular, there is a movement gap with a gradient from the outside to the inside when at least the upper end face of the lower door part, viewed from the side in a vertical longitudinal section, has one or more subsections with a negative gradient (gradient) viewed from the outside inwards towards the washing area , or has a continuous negative slope along its entire course from the outside inwards in the direction of the washing area. On the one hand, this ensures that, in particular in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, any liquid that may have entered the movement gap during the spraying operation of a running dishwashing program runs back into the washing area and does not escape to the outside or front of the entire door .

Even in the various opening positions of the overall door (with the upper door part closed), due to the gradient of the movement gap, liquid that may have got into the movement gap during the washing operation of a dishwasher program preferably runs out of the movement gap on the side of the overall door facing the washing area for as long (and will preferably collected by a collecting zone of the lower door part and / or runs back into the washing area), as the opening angle of the entire door relative to the vertical is smaller than the negative angle of inclination of the movement gap. The movement gap is thus emptied of any liquid before, when the entire door is opened, its opening angle relative to the vertical exceeds the negative angle of inclination of the movement gap. This improves the avoidance of liquid being able to run out through the movement gap to the front of the entire door.

Preferably, in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, the contour of the lower face of the upper door part runs largely parallel to the contour of the upper face of the lower door part in the vertical longitudinal section viewed from the side. As a result, the mutually facing end faces of the upper and lower door parts are designed to be complementary. This enables a movement gap with a defined gap size, in particular a very small gap width, between the facing end faces of the upper door part and the lower door part.

In the vertical closed end position of the entire door with the vertical closed end position of the Viewed from the upper door part, the movement gap from the washing chamber outwards to the front of the entire door, viewed preferably at least a partial section with a positive slope. As a result, liquid that gets into the movement gap during the spraying operation of a running dishwashing program inevitably always runs back into the washing area of the washing container. It is largely avoided that washing liquid can pass through the movement gap from the washing area to the front of the entire door and thus into the outside area at the installation site of the household dishwasher. The movement gap formed according to the invention between the upper door part and the lower door part, with its gradient from the outside inwards into the washing compartment of the washing compartment, largely ensures the tightness of the entire door in its vertical closed end position with the vertical closed end position of the upper door part. This is important because one or more liquid spray devices such as rotatable spray arms and / or rotatable or fixed spray nozzles can hit the washroom-side overlap zone between the two door parts with liquid spray jets under spray pressure when the domestic dishwasher is in operation.

The entrance into the movement gap on the flushing side is preferably lower than the front, outer exit of the movement gap. In the vertical direction, these ends of the movement gap, which are offset in height, are preferably between 0.6 cm and 12 cm apart.

Advantageously, according to an expedient development of the invention, the contour of the lower face of the upper door part can be designed to be essentially complementary to the contour of the upper face of the lower door part, so that in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, the vertical height or width the movement gap can be made very small along its depth (viewed from the outside to the inside of the wash cabinet). In particular, the movement gap can have an approximately constant gap width (viewed in the vertical direction). The vertical width of the movement gap can advantageously be implemented in particular less than or equal to 1 cm, preferably less than or equal to 0.5 cm. For example, the vertical gap height of the movement gap between the facing ends of the two door parts can be around 1.7 mm and the vertical gap height between a first cladding panel placed on the front side of the upper door part and a cladding panel placed on the front side of the lower door part can be equal to or less than 5 mm be.

In particular, it can be expedient in this context if the rear upper edge of the upper end face of the lower door part is lower than its front upper edge. This is because this requires a contour on the upper face of the lower door part with a gradient from the outside to the inside towards the wash cabinet.

If the upper face of the lower door part has a contour with a positive slope from the wash cabinet to the outside, ie towards the front, this represents a barrier against the rising or rising of liquid and / or dirt particles contained in it. In particular in the vertical closed end position the entire door with the vertical closed end position of the upper door part can thus during the respective washing phase or washing phase of a running dishwashing program, in which liquid is distributed in the washing area and sprayed onto the soiled items, such as items with food residues, a liquid passage from the washing area through the movement gap Front side of the entire door are counteracted. The steeper the contour of the upper face of the lower door part or, to put it more simply, the positive slope of the movement gap from the inside, ie from the wash cabinet to the outside to the front of the door assembly, the better the barrier effect against the rising or rising of liquid and / or dirt particles contained in this in the movement gap, or the better it can be avoided that liquid and / or dirt particles contained in this pass through the movement gap from the washing area to the front of the door arrangement.

If necessary, the contours of the opposite end faces of the upper door part and / or the lower door part can be designed in such a way that the movement gap between them has several sections with the same or different positive gradients from the washing area outwards to the front or front of the entire door or door arrangement viewed, ie viewed with the same or different negative slopes from the outside to the inside towards the wash cabinet. In particular, only a partial section of the total extent of the movement gap can therefore also have a gradient from the outside inwards towards the washing area. For example, one or more horizontal sections of the movement gap can alternate with one or more vertical sections of the movement gap. For example, the movement gap, viewed from the washing compartment to the front side, can be composed of a first horizontal gap section, an adjoining vertical gap section and a subsequent second horizontal gap section. In particular, the term “gradient” of the movement gap from the outside to the inside towards the washing area thus also includes at least one course section or subsection with a such a negative slope that it runs vertically, ie has an angle of 90 ° to the horizontal.

It can therefore already be sufficient if a section of the total extent of the movement gap, in particular the upper end section of the lower door part when viewed in a vertical longitudinal section, has a positive slope when viewed from the washing area outwards.

In addition, a negative slope or slope of the contour of the lower face of the upper door part (from the outside, i.e. viewed from the visible front inward into the wash cabinet in a longitudinal section) means that the lower face of the upper door part is the upper face in each of its open positions of the lower door part is covered at least in the area of the axis of rotation of the upper door part, so that liquids and / or dirt particles that fall onto the top of the upper door part from above, such as from items of dishes that are loaded into and / or removed from the upper crockery basket, do not can reach the movement gap between the upper face of the lower door part and the lower face of the upper door part - at least in a gap area on its axis of rotation - in a direct way (viewed in the vertical downward direction). In addition, a mechanical protection against direct reaching with the fingers of a hand in the opening gap is provided at least in the area of the rotation axis when closing the upper door part, since the movement gap is always covered at least in the area of the rotation axis from above by the lower wall section of the upper door part, so that there the movement gap is not freely accessible from above.

If in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, the lower end face of the upper door part, viewed in longitudinal section from the side, has a gradient from the outside to the inside and, according to an advantageous development, the distance between the axis of rotation of the upper door part and the lowest point of the body The lower face of the upper door part is equal to or greater than the thickness of the lower door part, viewed in the depth direction, at its upper face end section, then the upper face of the lower door part is completely overhanged by the upper door part in its horizontal opening end position viewed in the depth direction. In other words, the movement gap between the upper and the lower door part is overhanged by the upper door part along its entire depth (viewed from the outside to the inside).

For this purpose, it can be useful if, viewed in the longitudinal section from the side, the contour of the lower end face of the upper door part viewed from the inside to the outside is selected roughly as a straight line with a positive angle of inclination of at least 45 ° relative to the horizontal. The contour of the upper face of the lower door part expediently runs complementary to this contour of the lower face of the upper door part.

On the other hand, the entire door of the dishwasher would, for example, correspond to the 36 the WO 2015/190713 have a movement gap between the upper door part and the lower door part with a gradient from the inside to the outside, then in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, liquid would get into the movement gap, for example from the washing area of this dishwasher, especially during the washing operation. are discharged through this to the outside, which is undesirable. If the upper door part were to be opened, the movement gap would become freely accessible from above, so that liquid that drips down from items to be washed during unloading and / or loading into the movement gap, which is freely accessible from above, is guided to the outside through the gradient of this movement gap would be.

According to an advantageous development of the invention, it is advantageous if, in the vertical closed end position of the entire door with the vertical closed end position of the upper door part viewed from the washing area of the washing compartment, the upper door part has a greater height extension than the lower door part in relation to its front loading opening. When viewed in the horizontal end position of the door as a whole, the section of the inner door wall of the upper door part that comes to lie on the top side, which in its vertical closed end position is immersed in the washing area of the washing container or limits its loading opening, is longer in the depth direction than the section of the inner door wall that comes to lie on the top side lower door part, which in its vertical closed end position dips into the washing area of the washing container or limits its loading opening. An overall door divided in this way with a longer upper door part and a shorter lower door part viewed in the vertical direction in the vertical closed end position of the entire door (with the vertical closed end position of the upper door part) is advantageous because then with the upper door part open and the lower door part vertically fixed, in particular locked the upper crockery basket and / or a cutlery drawer arranged above or below it is or are more accessible to a user. In particular, the upper door part in the vertical closed end position of the entire door (with the vertical closed end position of the upper door part), viewed in the height direction, is so long that it then has such a large open end position in its approximately horizontal end position Cross-sectional opening of the front loading opening of the washing compartment of the household dishwasher reveals that an upper crockery basket together with an upper rotatable spray arm that may be attached to its underside or any other spraying device that may be attached to its underside from the washing area of the washing compartment through the released, upper opening cutout of the loading opening of the Rinsing container can be moved out collision-free and brought into position over the top of the approximately horizontally pivoted upper door part. The longer the section of the upper door part protruding from the washing container, in particular from its loading opening, in the approximately horizontal end position of the opening of the upper door part, the farther the upper crockery basket, together with an upper rotatable spray arm attached to its underside, or another, possibly The spray device attached to its underside is moved out of the wash cabinet and made to overlap or coincide with the top of the upper door part. This makes it easier to access the upper crockery basket from above. At the same time, the top of the section of the upper door part protruding freely from the loading opening of the washing container forms a drip protection or a collecting device for liquid and / or dirt particles that fall from above from the upper crockery basket into the items to be placed or removed. An additional drip protection, for example in the form of a tub that can be moved out of the washing compartment with the upper crockery basket, is not required. The above statements also apply in particular to a cutlery drawer that is possibly accommodated above the upper crockery basket in the washing area of the washing container.

In summary, the advantageously divided overall door with a longer upper door part and a shorter lower door part in particular has improved ergonomics for a user. Their manageability and operability is brought to a higher level for a user.

In practical tests it has been found that it is particularly advantageous if, in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, viewed from the washing area of the washing container, the height extension of the part of the upper door part that delimits the front loading opening of the washing container is between 55% and 80%. the height extension of the part of the overall door that delimits the front loading opening of the washing compartment is selected. In a household dishwasher whose washing container has a loading opening at the front with a height of about 65 cm, in the vertical closed end position of the entire door with the vertical closed end position of the upper door part viewed from the washing area of the washing container, the part of the lower door part delimiting the front loading opening preferably has a height extension between 13 and 30 cm, in particular by around 24 cm - 26 cm, and the part of the upper door part that delimits the front loading opening has a height of between 35 and 52 cm, in particular around 39 cm - 41 cm.

If the lower door part, viewed in the vertical closed end position of the entire door, extends within the front loading opening of the washing container, viewed preferably between 20% and 45% of the height extension of the vertical section of the entire door that delimits the loading opening, it is advantageously ensured that with conventional base heights between 5 cm and 20 cm of a base support on which the washing compartment is arranged, the upper door part in its approximately horizontal end position allows a user of normal body size a comfortable access height to the top of the upper door part in its approximately horizontal open position. In particular, the upper door part lies in its approximately horizontal end position at a height between 20 cm and 50 cm above a floor at the installation site of the household dishwasher.

According to an expedient development of the invention, the upper door part runs approximately horizontally in its open end position with its inner door wall and is locked in this approximately horizontal open end position by a locking device, in particular on the lower door part. In this horizontal end opening position of the upper door part, it functions as a kind of catching table for an upper crockery basket and / or a cutlery drawer that is moved out of the washing container via it. In this horizontal position of the upper door part, the upper crockery basket and / or the cutlery drawer can be aligned with a maximum possible extension length or drive-over length over the top of the upper door part.

In particular, it can be advantageous if the upper door part in its horizontal end position of the crockery basket with a spray device coupled below it on a pull-out or extension length of between 60% and 90% of the depth of the upper crockery basket from below to catch liquids and / or dirt particles overlap. This makes it convenient for a user to load and / or unload the upper crockery basket in practice. At the same time, the top of the upper door part in its horizontal open setting serves as a drip protection, ie to catch liquids and / or dirt particles that come from above The upper basket will fall down onto the top of the upper part of the door.

It can be useful if the pulling out or moving out movement of the upper crockery basket is limited by at least one limiting element to this length of movement between 60% and 90% of its depth in order to provide reliable drip protection on the underside through the horizontally pivoted upper door part. If the upper crockery basket were to be moved further out and its front wall would protrude beyond the front edge of the upper door part, then liquid droplets and / or dirt particles that might fall in the front area of the upper crockery basket when loading and / or unloading could not be caught by the upper door part, but fall on the floor. It can be particularly favorable that the movement of the upper crockery basket out of the washing container is limited in such a way that the moved out part of the upper crockery basket is brought to a standstill above the collecting zone, in particular the collecting trough of the horizontally pivoted upper door part.

The explanations given above apply accordingly to a cutlery drawer arranged in the washing area above and / or below the upper crockery basket, if this has the same depth as the upper crockery basket. However, since a common cutlery drawer usually has a smaller depth than the upper crockery basket, it can be brought up to 100% of its depth to coincide with the catchment zone of the approximately horizontally pivoted upper door part.

It can be particularly advantageous if the upper door part, in particular on its side facing the washing compartment of the washing compartment, expediently has at least one adding device for detergent, rinse aid and / or a decalcifying agent. This is because this adding device can then be made accessible to a user in an ergonomically more favorable or more convenient manner by only opening the upper door part, in particular bringing it into its approximately horizontal end position. This is because the upper door part has a lower mass than the overall door and a shorter lever arm from its axis of rotation to its upper end (viewed in the vertical closed end position), which is gripped by a user for opening and closing. The user no longer needs to bend down close to the floor, as he does with a conventional dishwasher, which is built into a niche between kitchen furniture below a worktop and stands on the floor, when he has to do the one-piece door to the front and bottom has opened and, for example, would like to pour detergent and / or rinse aid into the dispensing device mounted on and / or in the inner door wall of the one-piece door.

The adding device is preferably provided in the upper edge area, preferably facing the wash room, in particular on and / or in the upper cross member protruding on the wash room side of the upper door part when viewed in its vertical closed end position. If the upper door part is pivoted forward and downward from its vertical closed end position into its approximately horizontal open end position, the adding device moves away from the loading opening of the washing container against the depth direction. In its approximately horizontal opening end position, it lies in the area of the point furthest away from the loading opening (viewed in the depth direction) of the section of its movement circle it traverses when the upper door part is pivoted from its approximately vertical closing end position into its approximately horizontal opening end position. It assumes a height position that is significantly farther away from the floor than an adding device on the inside door side of a conventional, one-piece door. In particular, it is positioned in a height position between 20 cm and 50 cm above the floor in the horizontal opening end position of the upper door part. The approximately horizontally opened upper door part with the adding device coming to lie on the top is thus preferably at knee height or higher for an operator for his or her gender normal body size. This considerably improves the accessibility and thus the operability of the adding device for the respective operator.

According to a further expedient development of the invention, it can be particularly advantageous if the height extension of the upper door part on the washroom side is selected to be greater than the height extension of the lower door part on the washroom side such that (with the lower door part being vertically fixed) it is at the top in the approximately horizontal end position of the upper door part The inner door wall coming to lie lower than the body point of the upper crockery basket that protrudes furthest down, in particular lower than a component attached to the lower side of the upper crockery basket, such as a liquid distribution device, preferably a spray device such as an upper, rotatable spray arm, and in particular also when the upper crockery basket, if it is adjustable in height, is brought to its lowest height position for loading and / or unloading items to be washed. In this way it is ensured that the upper crockery basket including any component attached to it on the underside, preferably a liquid distribution device attached to it on the underside, in particular a spray device, without bumping, ie collision-free, over the approximately horizontally folded out or swung open, upper door part can be moved. In the approximately horizontal opening end position of the upper door part, there is a vertical free space distance, in particular of a few centimeters, between the top of the upper door part, which has been brought into its approximately horizontal opening end position, and the lowest point on the body of the upper crockery basket, which is possibly provided by an underside attached component such as a rotatable spray arm can be formed.

The same also applies to a cutlery drawer possibly arranged above or below the upper crockery basket.

It can also be advantageous if, in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, the lower edge of the upper door part on the washroom side is positioned higher than the highest point of the body on the front, in particular the upwardly protruding front handle of the lower crockery basket. This largely prevents the lower edge of the upper door part on the washroom side from touching the highest point on the body of this lower crockery basket when it is pivoted open.

According to a further expedient development of the invention, it can be advantageous that the inner door wall of the upper door part on the wash-room side comprises a first collecting zone for collecting liquids and / or dirt particles. In particular, the first collecting zone can be formed by a collecting trough, which is delimited at least by a left and a right side wall and an upper cross member extending over the width of the upper door part. This largely prevents liquids and / or particles of dirt from flowing or falling from the inner door wall of the upper door part on the washroom side onto the floor at the installation site of the household dishwasher.

In addition or independently of this, it can be advantageous if the inner door wall of the lower door part on the wash-room side comprises a second collecting zone for collecting liquids and / or dirt particles. This can in particular be formed by a collecting trough which is delimited at least by a left and a right side wall. When the entire door is opened, which is composed of the upper door part and the lower door part, two collecting areas or collecting zones, in particular collecting troughs, are provided for liquids and / or dirt particles on the top of the total height. When the lower crockery basket and / or the upper crockery basket and / or any cutlery drawer above or below the upper crockery basket is moved out, the entire door with its two collecting zones, in particular collecting troughs, serves as a drip guard to catch liquids and / or dirt particles. As a result, the floor in the vicinity of the installation site of the dishwasher remains largely dry and / or clean when loading and / or unloading items to be washed.

In this context, it can be useful that in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, the lower wall section of the upper door part, which overlaps the upper wall section of the lower door part on the wash cabinet side to form the overlap zone, is viewed as a cross member protruding into the wash cabinet is trained. In particular in the approximately horizontal end position of the opening of the upper door part, it is largely prevented that an amount of liquid collected by the first collecting zone and / or dirt particles collected by the first collecting zone can run down or fall into the washroom-side entrance of the movement gap, in particular onto the upper face of the lower door part .

The cross member can expediently be designed lower than the side walls of the inner door wall of the upper door part. This enables liquid to run off from the first collecting zone over the overlapping zone into the second collecting zone when the upper flap door or when the entire door (with door parts connected to one another) is tilted more and more to close without the liquid flowing over the sidewalls can run.

Additionally or independently of this, it can be advantageous that in the vertical closed end position of the entire door with the vertical closed end position of the upper door part viewed, a wall section of the lower door part, which lies below the overlap zone, is designed as a cross member protruding into the washing area. This prevents quantities of liquid and / or dirt particles that may have accumulated in the horizontal opening end position of the entire door, in particular in the second collecting zone, from entering the entry of the movement gap on the washing chamber side.

According to an advantageous development of the invention, it can be expedient if, in the closed end position of the upper door part, at least one sealing element closes the movement gap between the upper door part and the lower door part largely in a liquid-tight manner. This improves the tightness of the door assembly according to the invention, so that it is largely liquid- and / or vapor-tight to the outside when the Entire door (when door parts are connected to one another to form a unit) is brought into its vertical closed end position. Correspondingly, the door as a whole is liquid-tight to the outside in an improved manner when it is pivoted open into its horizontal end position.

It can be particularly favorable if, in the vertical closed end position of the entire door with the vertical closed end position of the upper door part, the sealing element is provided at least between the overlapping wall sections of the upper door part and the lower door part, in particular such that it protrudes in the direction of the wash cabinet. As a result, it also prevents spray jets from penetrating into the movement gap, which in particular from the lower spray arm hit the entry into the movement gap on the wash-room side.

To increase the ease of use of the door arrangement of the domestic dishwasher for a user, it can be particularly advantageous that the upper door part has a display and / or operating device. As a result, a household dishwasher can be provided in which the display and / or control device is visible to a user and / or accessible for operation both when the entire door is opened and when the upper door part is opened separately.

The display and / or control device is arranged in particular outside the first catchment zone of the upper door part assigned to the washing area and / or preferably higher than this catchment zone (viewed in the vertical closed end position of the entire door with the vertical closed end position of the upper door part). If the user opens the upper flap door, helpful information such as loading and / or unloading, dosing of detergent, rinse aid and / or softener, dishwashing programs, program duration, program end, etc ... can be displayed without the entire door should be opened. It is preferably possible for him to make a program selection and other settings via the operating device. The reading and / or input height is more comfortable for a user compared to a conventional dishwasher with a one-piece door, since the upper door part can be reached more ergonomically with the display and / or operating device. It is preferably about arm's length or less away from a user of normal height, in particular when the upper door part has been pivoted into its approximately horizontal end position. If the display and / or control device is arranged outside the first collection zone and in particular higher than this (viewed in the vertical closed end position of the entire door with the vertical closed end position of the upper door part), any moisture problems for its electrical or electronic components are largely avoided. It is particularly convenient if the display and / or control device is attached to the upper edge of the upper door part (viewed in the vertical closed end position of the entire door with the vertical closed end position of the upper door part) on the wash room side and / or on the top. As a result, a fully integrated household dishwasher can be provided in which the display and / or operating device is particularly conveniently visible to a user and / or accessible for operation both when the entire door is opened and when the upper door part is opened separately.

According to an advantageous development of the invention, it can be expedient that the display and / or operating device and / or the adding device of the upper door part are / is activated when the lower door part is fixed in a vertically aligned position and the upper door part is pivoted into an open position relative to it is, in which the display and / or operating device and / or the adding device are / is accessible to a user, and when the upper door part and the lower door part are coupled together as a complete door in an open position in which the display and / or Operating device and / or the adding device are / is accessible to a user.

In particular, it is advantageous if the display and / or operating device and / or the adding device are / is activated at least in the open end position of the upper door part.

According to an advantageous development of the invention, it can be useful that the display and / or operating device and / or the adding device of the upper door part can be supplied with electrical energy by an energy supply unit, which is arranged in particular in the base support below the washing compartment, both when the lower door part is fixed vertically aligned and opposite this the upper door part is pivoted into an open position in which the display and / or operating device and / or the adding device are / is accessible to a user, as well as when the upper door part and the lower door part are coupled together are pivoted open as a whole door in an open position in which the display and / or operating device and / or the adding device are / is accessible to a user. In particular, the display and / or operating device and / or the adding device can be supplied with energy via at least one energy supply line which continuously bridges the gap between the upper door part and the lower door part.

According to an advantageous development of the invention, it can be useful that the display and / or operating device and / or the adding device of the upper door part of a control and / or monitoring unit, which is arranged in particular in the base support below the washing compartment, by means of an or multiple control and / or control signals can be controlled and / or regulated, in particular via at least one control line that bridges the gap between the upper door part and the lower door part, both when the lower door part is vertically aligned and the upper door part in a Is pivoted open position, in which the display and / or operating device and / or the adding device are / is accessible to a user, as well as when the upper door part and the lower door part are coupled together as a complete door in an open position in which the display and / or operating device and / or the adding device for e to which users are / is accessible.

Furthermore, according to an advantageous development of the invention, it can be advantageous that a locking device secures the position of the lower door part in the vertical closing end position of the entire door during the pivoting of the upper door part, in particular locks it. The lower door part can be secured in position as soon as the user actuates a mechanical and / or electrical actuator such as a button that initiates the opening of the upper door part. This largely prevents the lower door part of the entire door from being opened forwards when the upper door part is stored, which could otherwise lead to incorrect operation, damage to the door arrangement or even injury to the operator.

In order to prevent the lower edge of the upper door part from rubbing against the lower crockery basket, it can be particularly useful that the distance between the axis of rotation of the upper door part and the front upper edge of the lower crockery basket is greater than the distance between the axis of rotation of the upper door part and the is the rear lower edge of the overlapping wall section of the upper door part facing the washing area.

Furthermore, for collision-free pivoting of the upper door part in relation to the lower door part, it can be advantageous that one or more joint parts are assigned to the upper door part and / or the lower door part in such a way that the distance between the axis of rotation of the upper door part and the lower front edge of the upper door part including any cladding panel applied to the front is smaller than the respective distance between the axis of rotation of the upper door part and any location on the upper end of the lower door part including any cladding panel applied to the front.

In particular, it can be advantageous if one or more hinge parts are assigned to the upper door part for its collision-free pivoting open and closed with respect to the upper face of the vertically fixed door part and / or with respect to the upper face edge of the washing compartment so that its resulting axis of rotation is from the front in the depth direction viewed in front of the plane of its outer wall and / or in front of the plane of the outer wall of the lower door part. If a panel is placed on the outer wall of the upper door part and the outer wall of the lower door part, it can be advantageous if the resulting axis of rotation of the upper door part runs within the front panel of the upper door part or the lower door part. In this way, the front gap between the two front panel panels of the upper door part and the lower door part in the closed end position of the entire door can be made smaller than or equal to a required kitchen furniture gap, in particular smaller than or equal to 0.5 cm.

For a collision-free opening and closing of the upper door part relative to the upper end face of the vertically fixed door part and / or opposite the upper end edge of the washing compartment, it can be particularly advantageous if the resulting axis of rotation for the upper door part is approximately in the height range of the front lower edge of the upper door part or the front lower edge of a cladding panel possibly attached to its front side, or approximately in the height area of the overlap zone between the lower wall section of the upper door part and the upper wall section of the lower door part as well as in front of the overlap zone when viewed in the depth direction. As a result, the upper door part in its horizontal opening end position can protrude from the front opening of the washing container with a sufficient length, viewed in the depth direction, to move an upper crockery basket and / or a cutlery drawer arranged above it out of the front opening of the washing container by the greatest possible length at the same time from below to be able to coincide with the protruding upper door part. In this way, the upper crockery basket and / or a cutlery drawer arranged above it can be moved far out of the washing area in front of the front opening of the washing compartment for good user accessibility and a drip protection can be provided for this by the horizontally pivoted, upper door part.

For this purpose, it can be particularly advantageous if the resulting axis of rotation for the upper door part is in the area of the front entrance of the Movement gap, which is present between the lower end face of the upper door part and the upper end face of the lower door part, or in the area of the separation gap, the cladding panels attached to the front, preferably slightly higher than the movement gap or separation gap. The latter advantageously ensures that the front lower edge of the cladding panel of the upper door part does not touch the upper end face of the vertically fixed lower door part when it is pivoted open.

In particular, it can be advantageous if one or more components, preferably pivot pins, of the one or more pivot joints of the upper door part viewed in height direction are arranged outside the movement gap provided between the upper door part and the lower door part, preferably higher than the movement gap . If a cladding panel is placed on the outer wall of the upper door part and on the outer wall of the lower door part, it can be advantageous for the one or more components, preferably pivot bolts, of the one or more pivot joints of the upper door part, viewed in the vertical direction, outside the separation gap are arranged between the two cladding panels, preferably higher than the separation gap. As a result, viewed from the front, the movement gap between the upper door part and the lower door part or the separation gap between any cladding panels attached to the front side in the vertical closed end position of the entire door remains continuously free over its entire extension length and is not interrupted or covered by components in the gap. As a result, aesthetic requirements for clear lines of the gap clearance between the upper and lower door parts or their facing panels that may be attached to the front are also met. In particular, it is made possible to adapt the free gap between the upper and lower door parts or between their cladding panels, which may be attached to the front, to the other common kitchen gaps of kitchen furniture such as kitchen drawers. This allows a consistent implementation of a given gap size in kitchen furniture and their built-in appliances.

If the fronts of the upper door part and the lower door part are provided with cladding panels, it can be useful that one or more recesses or recesses in the back of the cladding panel of the upper door part and / or the paneling panel of the lower door part to at least partially accommodate a or more components of the one or more pivot joints are provided for the upper door part.

For example, in a structurally simple manner, a left-hand and a right-hand, approximately horizontal pivot pin aligned in the width direction can be provided by means of support parts or brackets on the lower, fixed door part or on the left-hand and right-hand side strips of a frame part protruding upwards from the lower door part. Associated bearing bushes, which are attached to the upper door part, are placed on these two pivot pins. These are preferably provided in the area of the vertical side panels of the upper door part (viewed in the vertical closed end position). The pivot pins are expediently positioned with respect to their local position in such a way that the above-explained local position of the resulting rotational axis of the upper door part results.

For a proper pivoting of the upper door part forward and down, independent of the entire door, it can be particularly advantageous if the horizontal axis of the upper door part is arranged spatially in front of the lower horizontal axis of the entire door when viewed in the depth direction. This spatial arrangement of the two axes of rotation to one another advantageously avoids that space is lost in the washing area due to the upper door part that can be opened or swung open.

It can be structurally advantageous if the upper door part in its closed end position is enclosed along its two lateral side cheeks and along its upper outer cheek in a frame part that can be coupled to the lower door part or is firmly attached to it and protrudes upwards from it. As a result, the entire door construction becomes sufficiently rigid when the upper flap door is brought into its vertical closed end position and the entire door is opened. In addition, the upper flap door can be held stable in the frame part in all open positions and the torques caused by the opened upper flap door can be diverted from the frame to the lower door part or intercepted by it, especially when the lower door part is fixed in its vertical position by a locking device is. When the upper flap door is opened, the lower door part can then transfer the forces acting on it to the washing compartment.

Furthermore, it can be advantageous if the frame part terminates essentially flush with the respective inner wall of the washing compartment. As a result, the originally specified cross-sectional area of the loading opening of the washing compartment is retained. It can also be advantageous if the frame part has a strip width such that, viewed from the front, in a front edge zone of the washing container there is a sealing bed which delimits its loading opening and in which a door seal is provided for the entire door of the washing container, and possibly also one on the front edge attached to the rinsing container, outer stiffening frame, and / or a piping in the front gap between the washing compartment and adjacent kitchen furniture and / or a worktop largely covers the front. As a result, the frame part protects the door seal of the washing container, the outer reinforcing frame of the washing container, and / or the piping from splashes of liquid and / or soiling when the upper flap door is open and an upper crockery basket and / or a cutlery drawer, e.g. with dirty items such as dishes and / or cutlery is loaded.

The invention also relates to a door arrangement per se, which is designed according to the two door parts of the domestic dishwasher of claims 1 - 31, which can be connected to form an overall door, and / or the points explained above, and for closing and / or opening the front loading opening of the washing compartment of a domestic dishwasher is provided.

The above-explained and / or the other advantageous developments and / or developments of the invention reproduced in the subclaims can be used individually or in any combination with one another, except, for example, in the cases of clear dependencies or incompatible alternatives.

Further advantages and features of the invention and / or their advantageous designs and developments emerge from the exemplary embodiments of the subject matter of the invention shown in the drawing and described below.

1 shows, viewed obliquely from the front, a schematic three-dimensional representation of a household dishwasher GS that are in a niche between adjacent kitchen furniture KM underneath a kitchen worktop CAPE is preferably fully integrated. The front loading opening of the washing compartment of this household dishwasher GS is through an overall door or door arrangement GT locked, arising from an upper door part OT and a lower door part UT composed. When the two door parts OT , UT are coupled or connected to each other, so the entire door GT as a whole from its approximately vertical closed end position around a lower, horizontal axis of rotation extending in the width or transverse direction B. DAG Swivel open forwards and downwards into an approximately horizontal end position. The upper part of the door OT can be taken from its approximately vertical closed end position with the lower door part standing still vertically or in particular fixed UT separately around a specially assigned horizontal axis extending in the width direction B. DAO Swivel open forwards and downwards into an approximately horizontal end position. The two axes of rotation DAO , DAG are in the 1 indicated by dash-dotted lines. For better spatial orientation, a three-dimensional coordinate system is also drawn in at the location of a user in front of the domestic dishwasher. Its direction arrow B represents the width direction or transverse direction along which the kitchen furniture KM with the fully integrated household dishwasher GS are arranged like a line, its direction arrow T indicates the depth direction, which is perpendicular to the vertical front surface of the kitchen furniture KM or the entire door GT runs and into the interior of the respective kitchen furniture or the household dishwasher GS is directed, and its direction arrow H stands for the height direction, which runs in the vertical direction upwards.

Viewed from the front, the upper part of the door OT a greater height extension than the lower door part UT on. In particular, the upper door part is so long in the height direction H that it has such a large cross-sectional opening section of the front loading opening in its approximately horizontal opening end position LO of the washing compartment SB (see e.g. 2 ) of the household dishwasher GS reveals an upper basket OK together with an upper rotatable spray arm that may be attached to its underside OS or another spray device from the wash cabinet, possibly attached to its underside SR of the rinsing container SB through the released, upper opening cutout of the loading opening LO of the washing container can be moved out without collision. Here in the embodiment of 1 shows the outer wall of the entire door GT for example, a total height of about 77 cm. The outer wall of the upper door part has OT viewed in height direction H a length of about 42 cm. The outer wall of the lower part of the door UT has a vertical height extension of about 35 cm. It stands down in the base recess, which is open at the front SO the household dishwasher GS or the neighboring kitchen furniture KM with a protrusion into it.

The two door parts OT , UT In the exemplary embodiment, each preferably has a front facing panel MBO , MBU on. This is formed in particular by a furniture plate that is attached to the furniture fronts of the adjacent kitchen furniture KM is adapted or corresponds to a furniture front panel of the adjacent kitchen furniture. Between the upper part of the door OT and the lower part of the door UT is just a narrow separation gap TS Seen from the front, it is visible over the entire width of the household dishwasher GS extends continuously. It is designed like a joint or groove. Its gap width, viewed in the height direction H, preferably corresponds essentially to the specified kitchen furniture gap dimension of the adjacent kitchen furniture KM . This way the overall door gets GT the household dishwasher GS Viewed from the front, the appearance of two kitchen furniture drawers arranged one above the other, if the entire door GT is brought into their vertical closed end position and the upper door part OT also in its vertical Closing end position is. The height of the lower door part and / or the upper door part can expediently correspond to the height of conventional kitchen furniture drawers. This improves the design options for a kitchen manufacturer or kitchen planner. In particular, the uniformity of the fronts of kitchen furniture and built-in household appliances can be ensured throughout.

The 2 to 5 each show the rinsing container SB the household dishwasher GS from 1 together with a first advantageous embodiment of a door arrangement designed according to the invention in different opening and closing positions and the pivotable overall door GT as well as the independently pivotable upper door part OT .

In the wash cabinet SR is preferably a lower basket UK and an upper crockery basket at a height above this OK and possibly a cutlery drawer at the top, as here in the embodiment SU intended. Below the upper basket OK is an upper spray device, in particular an upper, rotatable spray arm OS with associated water supply pipe attached. A lower spray device, in particular a lower rotatable spray arm, is below the lower crockery basket UK , provided in and / or on the bottom of the washing compartment. For the sake of graphic clarity, this or this is in the 2 - 5 been omitted. The same applies to a roof spray device such as a rotatable or fixed roof shower that is above the cutlery drawer SU on the ceiling wall of the washing compartment SB is possibly provided on the washroom side.

The entire door GT is in the two door parts OT , UT preferably divisible in such a way that only in the vertical position of the lower door part UT the upper door part OT around its lower horizontal axis DAO from its vertical closed end position can be pivoted forward and down into various open positions up to its approximately horizontal open end position. In other words, the entire upper door part is OT Can be pivoted open by up to 90 ° from its vertical closed end position. So if the upper part of the door OT is pivoted open from its vertical closed end position by a maximum opening angle of about 90 °, it assumes its approximately horizontal open end position. The lower part of the door UT is preferably fixed or held in its vertical position, in particular locked when the upper door part OT should be opened and / or will be opened. For this purpose, a corresponding locking mechanism can preferably be between the lower door part UT and the rinsing container SB the domestic dishwasher, and / or between the lower door part UT and a base support or base component BA be provided on which the washing container SB is appropriate. Such a locking mechanism is in the 1 - 5 have been omitted for the sake of clarity. The axis of rotation running in the width direction B, ie horizontal axis DAO runs here in the exemplary embodiment (see the 2 ) especially in the lower edge area of the upper door part OT just above the dividing line or the dividing gap TS . The front separation gap TS , the one between the two front panel panels MBO , MBU is available, goes from the outside to the inside (to the wash cabinet SR of the rinsing container SB hin) viewed into a movement gap SP about that between the lower face URA of the upper part of the door OT and the upper face ORA the lower part of the door UT is present when the two door parts OT , UT firmly together to form the entire door GT are connected. The 2 shows the vertical closing end position of the entire door GT in a perspective view with the side wall of the washing compartment omitted SB from its wash cabinet SR viewed from obliquely forward. The entire door closes in this vertical closed end position GT the entire front loading opening LO of the rinsing container SB the household dishwasher. The loading opening LO shows the washing compartment viewed from the front SB considers a cross-sectional geometry that preferably corresponds approximately to a raised rectangle. The loading opening LO is opposite the front edge or the front end face SBS of the washing compartment SB in the depth direction T somewhat, in particular between 1 cm and 5 cm, set back. It is preferably through one of the entire door GT assigned door seal TDI (see in particular 11 ) limited in a sealing bed DIB in the front edge zone of the washing compartment SB is attached to the inside wall. This sealing bed DIB with the door seal held in it TDI preferably extends approximately along the vertical extension of the left and right side walls and along the width extension of the top wall of the washing compartment SB .

The upper part of the door OT points to its the wash cabinet SR facing inner door wall a left and a right, to the washing area SR protruding sidewall WLO , WRO , on its upper wall section one to the wash cabinet SR projecting cross member or cross cheek extending over the total width of the inner door wall WQO , as well as on its lower wall section URA one to the wash cabinet SR protruding towards the two side cheeks WLO , WRO connecting cross member or cross beam QTO on. Those cheeks WLO , WRO , WQO , QTO delimit a first trough-like catchment area all around AO on the inner door side of the upper door part OT . They form an all-round border for this RAO with a roughly rectangular shape.

In a corresponding manner, the lower door part UT one left and one right, to the wash cabinet SR protruding sidewall WLU , WLR on, which between them a second collection zone AU laterally bordered and the side cheeks WLO , WLR the upper border RAO continue. The lower wall section of the lower door part on the washroom side UT has one of the two side walls WLU , WRU connecting crossbar KR on that in the wash cabinet SR protrudes and the front, upwardly protruding snout SN of the bottom part of the washing compartment SB cantilevered. On the upper wall section on the washroom side ORA the lower part of the door UT is one of the two side cheeks WLU , WRU connecting cross member extending in the width direction QTU provided to the wash cabinet SR sticks out. This through the two side walls WLU , WRU , the upper cross member QTU and the lower cross member KR formed inner wall edge of the likewise approximately rectangular, trough-like collecting zone AU the lower part of the door UT is with ROUGH designated. In the vertical closed end position of the entire door GT are the side cheeks WLO , WRO and the upper cross member WQO the upper border RAO of the upper part of the door OT as well as the two side walls WLU , WRU the lower border ROUGH the lower part of the door UT with their respective, the wash cabinet SR facing, projecting, preferably planar, end face on the door seal on the washing compartment side TDI at. The entire door GT So emerges here in the embodiment with the side walls WLO , WLR , WLU , WRU of the two borders RAO , ROUGH as well as the upper cross member WQO preferably in the front opening of the washing compartment SB on.

In the vertical closed end position of the entire door GT (with vertical closing end position of the upper door part OT ) points from the wash cabinet SR of the rinsing container SB considered based on its front loading opening LO the upper door part OT On the wash room side, a greater height extension HO than the lower door part UT on. The height extension of the lower door part towards the washroom UT is in the 2 marked with HU. The mathematical relation or relation HO> HU applies.

In particular, it can be advantageous if the height extension HO of the upper door part on the wash-room side OT so greater than the height extension HU of the lower door part on the wash-room side UT selected that (with vertically fixed lower door part UT ) in the approximately horizontal end position of the upper door part OT its inner door wall IDO coming to lie at the top is lower than the body point of the upper crockery basket that protrudes furthest downwards OK , especially deeper than one on the underside of the upper crockery basket OK attached component such as a liquid distribution device, preferably a spray device as here in the exemplary embodiment, for example an upper, rotatable spray arm OS , is, especially when the upper basket OK if this is adjustable in height, it is brought into its lowest height position for loading and / or unloading items to be washed.

In particular, in this context, in the case of washing containers of conventional dimensions, it can be advantageous if the height extension HO of the upper door part is on the wash-room side OT between 55% and 80% of the height extension HO + HU of the entire door GT is.

In the vertical closed end position of the entire door GT viewed overlaps the upper part of the door OT with its lower wall section URA one in the wash cabinet SR facing, upper wall section ORA the lower part of the door UT on the wash room side with the formation of an overlap zone UZ . The overlapping lower wall section URA of the upper part of the door OT limits the wash space SR on a part of its height extension. As a result, during the washing operation of a running dishwashing program, with the washing liquid by means of one or more liquid distribution devices, in particular spray devices such as rotatable spray arms, spray nozzles, etc ..... in the wash cabinet SR of the rinsing container SB It is largely ensured that the movement gap is distributed, in particular sprayed, onto washware placed there in one or more receiving units such as, for example, crockery baskets and / or a cutlery drawer SP between the upper face EAST the lower part of the door UT and the lower face VAT of the upper part of the door OT On the wash room side along a normal or perpendicular to the inner door surface of the entire door GT is covered. Thus, liquid spray jets from the one or more liquid distribution devices, in particular spray devices such as a lower and / or an upper rotating spray arm, cannot enter the movement gap directly SP to meet. By having a lower wall section URA of the upper part of the door OT at least over the height extension of the movement gap SP between the two opposite end faces EAST , VAT of the upper part of the door OT and the lower part of the door UT away and as here in the exemplary embodiment is preferably also extended downward by an overlap section, there is an overlap zone on the wash-space side UZ formed as a first barrier against liquid entry into the movement gap SP acts into it. Thus the tightness of the entire door GT against the escape of liquid and / or vapor on its front side facing a user in the area in which the lower front side is VAT of the hinged, upper door part OT and the top face EAST in contrast, preferably with a vertical one Extension of fixed, in particular securable, preferably lockable, lower door part UT with the movement gap SP face each other. Through the overlap zone UZ is also a contamination of the movement gap SP between the upper door part OT and the lower part of the door UT counteracted by dirt particles, such as food residues, which are washed off the items to be cleaned by spray jets from one or more spray devices, such as rotatable spray arms. When the upper door part OT and the lower door part UT together to the entire door GT coupled, in particular connected, and the entire door GT is pivoted into an open position, in particular into its approximately horizontal end position, covers the overlap section which then comes to lie on top URA of the upper part of the door OT the edge section facing it, coming to lie under it ORA of the lower door part so that falling liquid droplets and / or dirt particles from the movement gap SP between the facing end faces VAT , EAST of the upper and lower door part OT , UT at least be held from above.

It can be particularly advantageous if the entire door is in the vertical closed end position GT (with vertical closing end position of the upper door part OT considered) a lower wall section URA , in particular the inner door wall, of the upper door part, the upper wall section ORA the lower part of the door UT in the overlap zone ZU on a height section between 2.5% and 50%, in particular between 5% and 25%, of the height extension of the front loading opening LO of the rinsing container SB limiting or closing vertical section of the lower door part UT Overlapped on the washroom side. This ensures that as much length as possible of the total height of the upper door part on the washroom side OT protrudes from the washing compartment when the upper door part is pivoted into its horizontal end position, so that despite the overlap zone UZ as long as possible for the upper basket OK (including the rotatable spray arm or some other spray device attached to the underside of this) over the top of the opened door part OT can be moved out and covered on the underside of this. In the case of a dishwasher with the usual dimensions of its washing container (viewed without a base support or without a base), its front loading opening LO For example, has a clear height of about 65 cm, and a lower door part, which closes or limits the loading opening with a section of about 24 cm - 26 cm in height (measured on the wash room side in its vertical position), has the overlap zone UZ preferably a height extension UL between 0.6 cm and 12 cm, in particular between 1.2 cm and 6 cm, on the wash chamber side, delimiting the loading opening.

The lower edge on the washroom side HUK of the upper part of the door OT is expediently positioned higher than the highest point on the front of the lower crockery basket UK . This is here in the exemplary embodiment in particular by an upwardly protruding, front handle HG of the lower basket UK educated. In this way, the rear bottom edge butts HUK of the upper part of the door OT not on the lower basket UK on when the upper door part OT compared to the vertically fixed, lower door part UT is swung open.

The entire door GT is in the 3 as a whole around your lower horizontal axis DAG in the area of the bottom of the washing compartment SB or in the area below the washing compartment SB arranged base carrier BA is provided, pivoted into an approximately horizontal end position. The upper part of the door OT overlaps with its lower wall section URA the wash cabinet SR facing, upper wall section ORA the lower part of the door UT on the wash room side with the formation of the overlap zone UZ . In the horizontal opening end position of the entire door GT is the overlap zone on the washroom side UZ on top of the overall door GT . In the 3 is out of the wash cabinet SR of the rinsing container SB the lower basket UK completely on top of the entire door GT moved out. He stands with his wheels or rollers preferably on the now in the horizontal opening end position of the entire door upwardly protruding side walls WLO , WRO and WLU , WRU of the upper part of the door OT and the lower part of the door. The drip pan is used for this AO of the upper part of the door OT and the drip pan AU the lower part of the door UT as a drip protection and / or as a dirt collector.

4th shows a schematic perspective view of the washing area SR The door arrangement of the viewed obliquely forward 2 , 3 in a position in which the upper door part is now OT compared to the vertically fixed, lower door part UT is pivoted from its vertical closed end position into an inclined partial open position, which is between its vertical closed end position (see 2 ) and its horizontal opening end position (see 5 ) lies. The upper part of the door OT In this inclined partially open position, protrudes over the upper face EAST the lower part of the door UT into the rinsing container SB protruding into it, ie the lower wall section or lower edge on the wash chamber side URA of the upper part of the door OT jumps in depth direction T compared to the upper face EAST of the lower door part, which is preferably left standing vertically UT into the rinsing container SB in front. This covers the lower wall section URA from above by the opening movement of the upper door part larger movement gap on the washroom side SP between the upper door part OT and the lower part of the door UT , especially the upper face EAST of the vertical lower part of the door UT preferably completely roof-like. This can cause liquid droplets and / or dirt particles to get into the collecting tray AO of the upper part of the door OT are possibly collected, across the opening gap that opens up on the wash cabinet side down into the wash cabinet SR flow or slide down, with the upper face EAST the lower part of the door UT covered from above and thus remains largely dry and clean.

5 shows a schematic perspective view of the washing area SR The door arrangement of the viewed obliquely forward 2 - 4th in a position in which the upper door part is now OT opposite the lower door part UT is pivoted into its approximately horizontal end position. The lower wall section formerly in the vertical closed end position of the upper door part on the wash-room side URA of the upper door part now overhangs the upper face EAST of the vertically fixed, lower door part OT in the depth direction from the outer edge AR at least as far as their inner edge on the wash chamber side IR . Its overhang US So it extends at least to the inner edge of the washroom IR , ie viewed in the depth direction at least up to the rear upper edge of the lower door part UT or even beyond that. It thus forms a canopy projecting in the depth direction for the upper end face EAST of the vertically fixed, in particular fixed, lower door part OT . In other words, the gap opened to the maximum extent on the washing area side by the pivoting movement of the upper door part SP between the lower face VAT of the upper part of the door OT and the upper face EAST the lower part of the door UT covered from above. That way, the top face remains EAST the lower part of the door UT largely dry and clean, especially when the upper basket OK and / or a cutlery drawer arranged above this SU from the wash cabinet SR of the washing compartment over the top of the upper door part OT has been moved out and unloaded cleanly washed items from the upper crockery basket and / or the cutlery drawer, or dirty items are placed in the upper crockery basket and / or the cutlery drawer.

In all open positions, especially including the horizontal end position, of the upper door part OT its upper side, that is, its inner door wall on the flushing side, is thus higher than the upper end face EAST the lower part of the door UT and towers over it. The upper front side is due to this roof that is always present EAST the lower part of the door UT Protected at least preventively against liquid droplets and / or dirt particles falling from above. This is advantageous, for example, when the upper part of the door is at the end of a dishwasher program OT in particular pivoted into its approximately horizontal end position and the upper crockery basket OK and / or the upper cutlery drawer SU from the rinsing container SB is moved out to unload clean washed items. This is because it can happen that residual liquids that have collected in depressions in items to be washed flow down or drip off and onto the upper side of the pivoted, upper door part formed by the inner door wall on the washroom side OT hit. Will be the upper door part OT pivoted into an open position, in particular into its horizontal end position, and the upper crockery basket OK and / or the cutlery drawer arranged above it SU moved out through the then released, upper section of the loading opening BS and dirty items to be cleaned, such as dishes, glasses, cups, cutlery, etc. placed in the upper crockery basket and / or the cutlery drawer, it can happen that liquids and / or dirt particles, such as leftovers, from the dirty items to be washed down onto the top of the upper door part formed by the inner door wall on the washroom side OT falling down. Due to the roofing or overhang of the upper front side, which is always ensured in all open positions including the approximately horizontal closed end position of the upper door part EAST the lower part of the door UT Liquids and / or dirt particles falling from above can be prevented from this or from direct penetration into the movement gap between the upper door part on the wash-room side OT and the lower part of the door UT be held. In particular, the upper face remains EAST of the lower door part, which preferably remains stationary in the vertical direction UT always sufficiently dry and / or clean.

It can be particularly favorable when in the approximately horizontal end position of the opening of the upper door part OT its the lower part of the door UT facing wall section URA the inner edge IR the upper face, ie the rear upper edge of the upper face of the lower door part (viewed in its vertical position) with a protrusion length US by at least 1.4%, in particular between 2.5% and 25%, of the vertical height on the washing chamber side of the section of the upper door part delimiting the front loading opening and protruding into the washing chamber. In the case of a dishwasher with the usual dimensions of its washing container, such as 65 cm clear inner height or height of the front-side limiting opening and a lower door part, the loading opening with a section of, for example, about 24 cm - 26 cm in height (measured on the washing room side in its vertical position) closes or limited, it can be advantageous in practice if the upper door part in its approximately horizontal end position of the washroom the wall or the rear upper edge of the lower door part with a projection length US protrudes into the wash cabinet by at least 0.5 cm, in particular between 1 cm and 10 cm.

The division of the two door parts OT , UT with regard to their height extension is expediently chosen such that the upper crockery basket OK together with the upper spray arm coupled to its underside OS or other spray device so far over the top of the horizontally opened, upper door part OT it is possible to move out that between 60% and 90% of the depth extension TL of the upper basket OK to coincide with the depth extension AL of the upper part of the door OT can be brought into its horizontal end position. In particular, the upper basket OK if possible with the catchment zone AO of the upper door part brought to cover. This largely prevents liquid droplets and / or dirt particles from getting onto the floor at the installation location of the household dishwasher, but rather in the tub-shaped collecting zone AO to be collected. If a cutlery drawer such as SU above the upper basket OK is provided, it can due to its opposite to the upper crockery basket OK usually less depth extension optimally up to 100% of their depth extension to cover with the upper-side collecting surface or collecting zone AO of the upper part of the door OT to be brought.

A delimiting element is expediently provided that the extension length or extension length of the upper crockery basket to the maximum possible overlap length with the top of the upper door part OT limited. This delimitation element is in the 8th for the sake of simplicity of the drawing, only indicated schematically by dash-dotted lines and denoted by BGE. A corresponding delimitation element can optionally also be used for the cutlery drawer SU be provided.

The upper part of the door OT points to its the wash cabinet SR of the rinsing container SB facing side at least one adding device ZV for cleaning agents, rinse aid, and / or descaling agents. In particular, the adding device ZV within the upper cross member protruding on the wash-chamber side WQO of the upper part of the door OT intended. In the vertical closed end position of the entire door GT (please refer 2 ) the adding device is located ZV thus in an area of the inner door surface of the entire door GT , which is acted upon with washing liquid during the washing operation of a dishwashing program, ie becomes wet.

Additionally or independently of the adding device ZV has the upper door part OT a display and / or control device ABV on. This is in particular outside the recess of its collecting zone AO (in the horizontal opening end position of the entire door GT considered) and is therefore outside of the area of the inner door surface of the entire door that is exposed to washing liquid during the washing operation of a dishwashing program and becomes wet GT . In the vertical closed end position of the entire door GT the display and / or operating device is considered ABV preferably higher than the collection zone AO of the upper part of the door OT intended. It is preferably on and / or in the upper face of the upper door part OT arranged. In the 3 is a possible position of the display and / or control device ABV in the area of the upper edge of the upper door part OT additionally drawn in dash-dotted lines. Once the upper door part OT is pivoted from its vertical closed end position into an open position, the display and / or control device ABV Visible and accessible for a user or an operator from above.

The display and / or control device ABV and / or the adding device ZV of the upper part of the door OT are / is expediently activated when the lower door part OT vertically aligned is fixed and opposite this the upper door part OT is pivoted into an open position in which the display and / or operating device ABV and / or the adding device ZV are / is accessible to a user, and if the upper door part OT and the lower door part UT coupled together as a complete door GT are pivoted into an open position in which the display and / or operating device ABV and / or the adding device ZV are / is accessible for a user from above.

The, preferably in the area of the upper edge, ie the free, outer end of the upper door part OT and thus also the entire door GT provided display and / or control device ABV as well as the adding device ZV are each from an energy supply unit EV in particular in the base carrier BA below the rinsing container SB can be arranged to be supplied with electrical energy, both when the lower door part UT vertically aligned is fixed and opposite this the upper door part OT is pivoted into an open position in which the display and / or operating device ABV and / or the adding device ZV are / is accessible to a user, as well as if the upper door part OT and the lower door part UT coupled together as a complete door GT in an open position, is in particular pivoted into a horizontal end position in which the display and / or operating device ABV and / or the adding device ZV are / is accessible to a user. For this purpose, it can be useful that from the energy supply unit EV at least one power supply line EL to the adding device ZV and / or the display and / or control device ABV is led. The energy supply unit EV and the power supply line EL are in the 3 each indicated by dash-dotted lines. The energy supply line preferably bridges the movement gap throughout SP between the upper door part OT and the lower part of the door UT . Similarly, it can be particularly expedient that the display and / or control device ABV and / or the adding device ZV of the upper part of the door OT from a control and / or monitoring unit CO in particular in the base carrier BA below the rinsing container SB can be arranged, can be controlled and / or regulated by means of one or more control and / or control signals, both when the lower door part UT vertically aligned is fixed and opposite this the upper door part OT is pivoted into an open position in which the display and / or operating device ABV and / or the adding device ZV are / is accessible to a user, as well as when the upper door part and the lower door part are coupled together as a complete door and pivoted into an open position in which the display and / or operating device ABV and / or the adding device ZV are / is accessible to a user. At least one control line is expedient for this purpose SL intended. The control and / or control unit CO as well as the control line SL are in the 3 each indicated by dash-dotted lines. The control line SL leads from the control and / or monitoring unit CO in the base carrier BA into the interior of the lower door part UT , bridges the movement gap SP between the upper and lower door part and then leads to the adding device ZV and / or the display and / or control device ABV .

• 6 zeigt in räumlicher Darstellung vom Spülraum SR des Spülbehälters SB der Haushaltsgeschirrspülmaschine GS her betrachtet als Einzelheit die modifizierte Gesamttür bzw. Türanordnung GT* für die Haushaltsgeschirrspülmaschine GS von 1 in ihrer vertikalen Schließendstellung, d.h. sowohl ihr oberes Türteil OT als auch ihr unteres Türteil UT sind jeweils vertikal ausgerichtet und miteinander verbunden.

The 6th - 8th each schematically show an advantageous door arrangement GT * opposite the door arrangement of the 2 - 5 is modified or modified. The one for the door arrangement GT the 2 - 5 The statements and explanations made above apply to the door arrangement GT * the 6th - 8th in an analogous manner, unless the following information deviates from this:

• 6th shows a spatial representation of the wash cabinet SR of the rinsing container SB the household dishwasher GS The modified overall door or door arrangement is viewed as a detail GT * for the household dishwasher GS from 1 in their vertical closed end position, ie both their upper door part OT as well as the lower part of the door UT are each aligned vertically and connected to one another.

As with the door layout GT the 2 - 5 points here with the modified door arrangement GT * the upper door part OT on his the sink SR facing inner door wall I DO also a left and a right, to the wash cabinet SR protruding sidewall WLO , WRO , on its upper wall section one to the wash cabinet SR protruding over the entire width of its inner door wall I DO extending cross member or cross beam WQO , as well as on its lower wall section URA one to the wash cabinet SR protruding towards the two side cheeks WLO , WRO connecting cross member or cross beam QTO on. Those cheeks WLO , WRO , WQO , QTO delimit a first trough-like catchment area all around AO on the inner door side or inner door wall I DO of the upper part of the door OT . For this they form an all-round border with an approximately rectangular shape.

In a corresponding manner, the lower door part UT on its inner door wall IDU one left and one right, to the wash cabinet SR protruding sidewall WLU , WLR on, which between them a second collection zone AU laterally bounded and with respect to their inner edges roughly in line with the inner edges of the side walls WLO , WLR the upper edge of the upper door part. The lower wall section of the lower door part on the washroom side UT has one of the two side walls WLU , WRU connecting crossbar KR on that in the wash cabinet SR protrudes and the front, upwardly protruding snout SN of the bottom part of the washing compartment SB cantilevered. On the upper wall section on the washroom side ORA the lower part of the door UT is one of the two side cheeks WLU , WRU connecting cross member extending in the width direction QTU provided to the wash cabinet SR sticks out. The two side cheeks WLU , WRU , the upper cross member QTU and the lower cross member KR thus form a border on the inner wall of the approximately rectangular, trough-like collecting zone AU the lower part of the door UT .
In contrast to the door arrangement GT the 2 - 5 is the upper part of the door OT now in a frame part RA as a flap door rotatable around a horizontal axis DAO mounted in such a way that it can be pivoted forward and downward. The frame part RA is on the lower part of the door UT firmly attached and protrudes from this upwards. It points above the lower door part UT an upper, approximately rectangular, free opening cutout, ie a breakthrough opening for receiving the upper door part OT on. The upper part of the door OT is in its vertical closed end position along the outside of its left and right outer cheek WLO , WLR as well as its upper outer cheek WQO in this upper section of the frame part RA bordered by this laterally. The upper part of the door OT thus sits as a flap door in the upper, free receiving cutout or opening of the frame part RA . The frame part RA consists of a left and a right sidebar as well as an upper transverse bar that connects them. It thus has the geometric shape of an upside-down U. The outer edges of its two side strips are roughly in line with the outer edges of the left and right side panels WLU , WLR the lower part of the door UT . The frame part RA in particular ensures on the one hand that the upper door part OT in its closed end position with the lower door part UT sufficiently tight to the entire door GT * can be connected and thus the door network of the entire door GT * is sufficiently mechanically stable. On the other hand, the upper door part OT in the opening of the frame part RA laterally on the vertical struts or vertical side strips in a structurally simple manner rotatably mounted.

For this purpose, for example, is in the two vertically extending side strips of the frame part RA each a pivot pin DBL of a swivel joint DGL for the upper door part OT intended. The bracket HA of the respective pivot pin DBL is in the area of the lower end of the approximately rectangular cutout of the frame part RA in the respective sidebar above the upper face EAST the lower part of the door UT or above the cladding panel attached to the front MBU intended. In other words, there is both a first pivot pin DBL perpendicular to its bracket HA receiving left sidebar of the frame part RA as well as a second pivot pin DBL perpendicular to its bracket HA receiving right sidebar of the frame part RA each along the common axis of rotation DAO in the width direction in its approximately rectangular receiving cutout or opening cutout facing one another. It is preferably higher than the free movement gap SP that is between the lower face VAT of the upper part of the door OT and the upper face EAST the lower part of the door UT is available. This leaves the horizontal parting line or the parting gap TS between the lower panel MBU and the upper trim panel MBO on the front of the door assembly GT * consistently free.

Along the top face of the upper door part OT facing border edge of the upper transverse strip of the frame part RA as well as along the side panels of the upper door part OT facing edging edges of the side strips of the frame part RA can expediently each be provided an elongated sealing element. Overall, a frame seal then results in the form of an upside-down U. For the sake of clarity in the drawing, such a frame seal is in the 5 - 8th been omitted. If necessary, a sealing element can alternatively be attached to the corresponding outer edges of the upper door part OT attach the from the top cross bar and the two side bars of the frame part RA be framed when the upper door part is brought into its closed end position and the opening cutout in the frame part RA locks.

The frame part RA is designed in such a way that it is about as far as the upper cross member WQO , the right and left side panels WLO , WRO the inner door wall or wash cabinet side of the upper door part OT and / or the two side walls WLU , WRU the lower part of the door UT towards the wash cabinet SR stands out. The frame part RA , the upper cross member bordered laterally from above WQO , possibly the right and left side cheek bordered by him laterally or laterally WLO , WRO the inner door wall or wash cabinet side of the upper door part OT , and / or the two side walls WLU , WRU the lower part of the door UT come with their, preferably planar, end faces protruding into the washing area with those on the front, inner edge of the washing container SB provided door seal TDI (please refer 11 ) in contact, ie are in contact with this when the entire door GT * into their vertical closed end position (with vertical closed end position of the upper door part OT ) is brought. The entire door GT * So emerges here in the embodiment with the frame part RA and the sidewalls WLO , WLR , WLU , WRU of the two borders RAO , ROUGH as well as the upper cross member WQO preferably in the front opening of the washing compartment SB on.

The inside, in the opening on the front of the washing compartment SB submerged frame part RA has a laterally protruding flange on the front face of its upper cross member and on its two side strips FL on. Such a flange is also laterally from the front of the two side walls WLU , WRU the lower part of the door UT from. This flange FL lies in the vertical position of the entire door GT * outside of the wash cabinet that gets wet when a dishwasher program is running SR in front of the front edge SSB of the washing container SB . On the front outer door wall ODO of the upper part of the door OT is the cladding panel MBO appropriate. On the front of the outer wall OTU of the lower door part UT is the lower panel MBU attached.

The upper part of the door OT is in the frame part RA around a specially provided horizontal axis of rotation running in the width direction DAO opposite the lower, vertically fixed door part UT mounted so that they can be swiveled forward and downward in such a way that it in the vertical closed end position of the entire door GT * with the upper part of the door closed OT viewed with a lower wall section or edge URA one in the wash cabinet SR of the rinsing container SB facing, upper wall section or edge ORA the lower part of the door UT on the wash room side with the formation of the overlap zone UZ overlaps and thus the wash cabinet SR on a section UL its height extension LOH (see also 3 ) limited. #

Here is the movement gap SP , the one between the facing end faces EAST , VAT of the upper part of the door OT and the lower part of the door UT is present on the inside by the opposite of the upper face EAST the lower part of the door UT protruding lower edge section URA of the upper door part covered on the washroom side. In the washing mode of a running dishwashing program, during which one or more liquid distribution devices, in particular spray devices, such as rotatable spray arms, in the washing area SR of the washing compartment SB Spray jets are emitted, it is thus largely avoided that the movement gap SP is hit or acted upon by one or more spray jets directly or directly on the wash space side. The overlap zone UZ with which the lower wall section URA of the upper part of the door OT the wash cabinet SR of the rinsing container SB facing, upper wall section ORA the lower part of the door UT Overlaps on the washroom side, thus ensuring preventive sealing of the movement gap SP from the wash cabinet getting wet SR here.

The overlap zone UZ preferably extends over a partial length between 2.5% and 50%, in particular between 5% and 25%, of the height extension HU of the loading opening LO of the rinsing container SB limiting portion of the lower door part UT . Indicates the loading opening LO of the washing compartment, for example, has a clear height of around 65 cm and closes the lower door part UT the loading opening LO with a height section of, for example, approximately 24 cm to 26 cm, the overlap zone UZ one on the wash chamber side, the loading opening LO limiting height extension preferably between 0.6 cm and 12 cm, in particular between 1.2 cm and 6 cm.

At the same time, the upper part of the door protrudes OT with its lower wall section URA the wash cabinet SR of the rinsing container SB facing, upper wall section ORA the lower part of the door UT On the wash room side in every open position up to its approximately horizontal end position. In other words, the lower edge section on the wash-space side stands URA of the upper part of the door OT in every open position (including the approximately horizontal end position) of the upper door part OT opposite the upper face EAST the lower part of the door UT in depth direction T into the rinsing container SB into it. These projections of the upper door part OT the modified door arrangement GT * correspond to those of the upper part of the door OT the first door assembly GT - as in the 4th . 5 illustrates - and are not shown in separate figures.

As with the door layout GT the 2 - 5 points here too with the modified door arrangement GT * the interior door wall on the washroom side I DO of the upper part of the door OT a first catchment area AO on that of a left and a right side cheek WLO , WRO and an upper cross member connecting the side cheeks WQO is limited. In the vertical closed end position of the entire door GT * with vertical closing end position of the upper door part OT considered is the lower wall section URA of the upper part of the door OT that is the top wall section ORA the lower part of the door UT forming the overlap zone UZ Overlapped on the wash cabinet side as one in the wash cabinet SR protruding cross member QTO educated. The cross beam QTO is preferably lower than the side walls WLO , WRO the inner door wall I DO of the upper part of the door OT educated. This shows the first catchment zone AO the inner door wall I DO of the upper part of the door OT On the wash compartment side, a preferably approximately rectangular tub shape or trough shape. The interior door wall on the washroom side IDU the lower part of the door UT has a second collection zone AU on that of a left and a right side cheek WLU , WRU , an upper cross member QTU that went into the wash cabinet SR protrudes and a lower one, towards the wash cabinet SR protruding cross member KR is limited. This means that the lower door part also points UT an approximately rectangular collecting pan or trough. Will the whole door GT * brought into an open position or, in particular, into its approximately horizontal end position, liquid droplets and / or dirt particles, which may be deposited in and / or the upper crockery basket during the loading and / or unloading process of items to be washed OK and / or the cutlery drawer arranged above it SU fall down in the two catchment areas AU , AO to be collected. Will only be the upper part of the door OT opened, in particular brought into its approximately horizontal end position, while the lower door part UT is fixed vertically, the first catchment zone is used AO to catch liquid droplets and / or dirt particles when loading and / or unloading the upper crockery basket OK and / or the cutlery drawer arranged above it SU falling down.

That in the frame part RA Upper door part pivoted open OT the door arrangement GT * points to its the wash cabinet SR of the rinsing container SB facing side an adding device ZV for cleaning agents, rinse aid, and / or descaling agents. This adding device ZV is for a user ergonomically accessible when he is the upper door part OT brings into an open position, in particular in its approximately horizontal end position. Because he no longer needs to bend down to the floor, as he does with a conventional dishwasher, which is built into a niche between kitchen furniture below a worktop and stands on the floor, in order to, for example, add cleaning agents and / or rinse aid to the on and / or or to fill in the addition device attached to the inner door wall of the conventional, one-piece door when he has brought the conventional, one-piece door, for example, into its approximately horizontal end position.

The top door part of the door assembly GT as well as the upper door part or the one in the frame RA pivoted door flap of the modified door arrangement GT * forms in his or her approximately horizontal end position of the opening a kind of table on which the adding device is on the top ZV is freely accessible to a user. The adding device ZV is expediently in an upper wall section on the wash chamber side, in particular in the upper cross member WQO , the upper part of the door OT appropriate. Will be the upper door part OT from its vertical closed end position forward and down around its axis of rotation DAO pivoted into its approximately horizontal end position, the adding device moves away ZV against the depth direction T from the loading opening LO of the rinsing container SB . In the approximately horizontal end position of the opening of the upper door part, it lies outside the washing compartment in the region of the furthest from the loading opening LO (viewed in the depth direction T) distant point of a movement circle section, which you when pivoting the upper door part OT from its vertical closed end position to its approximately horizontal open end position by approximately a pivoting angle of 90 °.

Furthermore, the upper door part OT the modified door arrangement GT * also a display and / or control device ABV on. In particular, it is outside the depression of the collecting zone AO intended. In the vertical closed position of the upper door part OT the display and / or operating device is considered ABV preferably higher than the collection zone AO intended. It is preferably on and / or in the upper face of the upper door part OT arranged. In the 6th is a possible position of the display and / or control device ABV in the area of the upper edge of the upper flap door OT additionally drawn in dash-dotted lines. Once the top flap door OT is brought into an open position, it is thus visible and accessible to a user from above.

The display and / or control device ABV and / or the adding device ZV of the upper part of the door OT the modified door arrangement GT * are / is expediently activated when the lower door part UT , vertically aligned and opposite this the upper door part OT is pivoted into an open position in which the display and / or operating device ABV and / or the adding device ZV are / is accessible to a user, and if the upper door part OT and the lower door part UT coupled together as a complete door GT * are pivoted into an open position in which the display and / or operating device ABV and / or the adding device ZV are / is accessible to a user.

In the vertical closed end position of the modified overall door GT * (with vertical closing end position of the upper door part OT ) points from the wash cabinet SR of the rinsing container SB considered based on its front loading opening LO the upper door part OT On the wash room side, a greater height extension HO than the lower door part UT on. The height extension of the lower door part towards the washroom UT is in the 6th marked with HU. The mathematical relation or relation HO> HU applies.

In particular, it can be advantageous if the height extension HO of the upper door part on the wash-room side OT even with the modified door arrangement GT * so greater than the height extension HU of the lower door part on the wash-room side UT it is selected that (with vertically fixed lower door part UT ) in the approximately horizontal end position of the upper door part OT whose inner door wall coming to lie on top I DO deeper than the point on the body of the upper basket that protrudes furthest down OK , especially deeper than one on the underside of the upper basket OK attached component such as a liquid distribution device, preferably a spray device as here in the exemplary embodiment, for example an upper, rotatable spray arm OS , is, especially when the upper basket OK if this is adjustable in height, it is brought into its lowest height position for loading and / or unloading items to be washed.

In particular, in this context, in the case of washing containers of conventional dimensions, it can be advantageous if the height extension HO of the upper door part is on the wash-room side OT between 55% and 80% of the height extension HO + HU of the entire door GT is.

The 7th shows a schematic spatial representation of the washing area SR of the rinsing container SB Seen from here, the entire door or door arrangement is partially cut open GT * the 6th in their vertical closed end position with the upper closed position Door part OT . It is a left-hand section of the upper door part designed as a flap door OT in the opening of the frame part RA omitted. Just a right section of the upper door part OT closes the cutout in the frame part RA . This will make the overlap zone UZ visible in vertical section. Between the lower face VAT of the upper part of the door OT and the upper face EAST of the lower, vertically fixed door part UT becomes the movement gap SP visible. This runs from the outside to the inside to the wash cabinet SR viewed on a partial section initially approximately horizontally or horizontally and then goes into a sloping downward section and finally into a vertical section VA above, the one between the lower edge or wall section that overlaps on the wash chamber side URA of the upper part of the door OT and the vertically upwardly standing, upper edge section or wall section ORA the lower part of the door OT runs. In the movement gap SP is housed at least one sealing element that the movement gap SP between the upper door part OT and the lower part of the door UT largely liquid-tight. For example, here in the embodiment of 7th a linear seal DI is provided in a sealing bed, in particular in a groove that is in the upper end face EAST the lower part of the door UT facing, opposite, lower face of the upper door part OT is provided. The sealing bed with seal DI extends over the entire width of the upper door part OT away. The seal DI stands out of its sealing bed in the direction of the upper end face facing it EAST the lower part of the door UT so far that it is in the vertical closed end position of the upper door part OT at the top EAST the lower part of the door UT is applied. Conversely, it is also possible that a corresponding sealing element is on the upper face EAST of the vertically fixed lower door part UT is provided.

In addition or independently of this, it may be useful that the entire door is in the vertical closed end position GT * with vertical closing end position of the upper door part OT considers a sealing element DI * between the overlapping wall sections URA , ORA of the upper part of the door OT and the lower part of the door UT is provided. This sealing element DI * can, for example, on the outside of the door inner wall facing away from the washroom I DO of the upper part of the door OT be provided as a sealing strip which extends outwards in the direction of the inner door wall of the lower door part on the wash-room side UT stands out. The upper wall section on the washroom side ORA the lower part of the door OT can be on the height position of the sealing element DI * one in the direction of the sealing element DI * have protruding elevation, so that the upper door part OT in its vertical closed end position with sufficient contact pressure on the sealing element DI * presses. This is how the movement gap is SP Sealed in a liquid-tight manner in height, depth and width direction, so that in the washing operation of a running dishwashing program, when washing liquid is sprayed in the washing compartment by means of one or more liquid distribution devices, in particular spray devices such as an upper rotatable spray arm, a lower rotatable spray arm, a roof shower provided at the top or a roof top becomes, not to the front of the overall door through the motor gap SP can get through.

Generally speaking, the movement gap SP from the outside in to the wash cabinet SR viewed due to its obliquely inward sloping section on the wash-room side and the adjoining vertical section on the wash-room side VA a gradient. Even when spray jets come from below, for example from a lower, rotatable spray arm, the one in the area of the bottom wall of the washing compartment below the lower crockery basket UK is provided in the entry of the movement gap, which is open from below and is on the flushing side SP hit, the liquid will be due to the incline of the movement gap on the wash chamber side (viewed from the outside in) SP in the wash cabinet SR run back.

The upper cross member QTU the lower part of the door OT runs in such a way that its upwardly directed end face is below the lower edge of the lower, overlapping wall section URA of the upper part of the door OT , ie lower than this. This forms the approximately vertical closed end position of the entire door GT * with vertical closing end position of the upper door part OT the upper cross member in the liquid spray mode of a running dishwashing program QTU a barrier for liquid droplets and / or dirt particles. Because the upper cross member QTU the lower part of the door OT blocks the entrance in a vertical section on the wash room side VA of the movement gap SP inside. It acts like a cover strip, so that liquid spray jets, which come from below, such as coming from a lower spray arm, and are directed upwards, from the cross member QTU bounce back, preferably downwards, and not directly into the entrance of the movement gap on the wash chamber side SP can meet.

In the 7th are in the lower part of the lower part of the door UT a left and a right hinge lever SHL, SHR are also drawn in on its left and timely side wall. The entire door GT * can be placed with these hinge levers SHL, SHR on the corresponding pivot bolts running in the width direction of a hinge plate mounted on the left and right of the base support and / or the washing compartment. The entire door GT can thus be rotated around a lower, horizontally extending axis of rotation, that is to say extending in the width direction B. DAG swivel forward and downward (see 1 ).

The frame part protruding upwards RA points on its left-hand and right-hand side strips in the direction of the upper door part OT protruding pins or bolts ARV on that as a counter stop for locking the upper door part OT serve in its horizontal end position. These counter attacks ARV are opposite the inner wall I DO of the upper part of the door OT to the wash cabinet SR offset in the left-hand and right-hand vertical strut or side bar of the frame part RA intended.

8th shows schematically in a spatial representation viewed from the side with a view to the front to the inside of the now for better clarification of the door arrangement GT * Front panel shown dismantled MBO of the upper part of the door OT a section of the door arrangement GT * the 6th , 7th in the area of the facing end faces of the upper door part OT and the lower part of the door UT in the vertical closed end position of the entire door GT * with vertical closing end position of the upper door part OT . In the left-hand and right-hand vertical strut or side bar of the frame part RA is the bracket HA with a swivel bolt or pin DBL provided in such a way that the axis of rotation extending in the width direction DAO of the upper part of the door OT viewed from the front in front of its outer door wall ODO runs. The bracket HA or generalizes the joint part DGL partially protrudes into a on the back of the upper panel MBO provided recess or recess ASL inside. By having the axis of rotation DAO as far forward as possible in front of the outer door wall ODO of the upper door part TO is offset, the front lower edge of the cladding panel MBO of the upper part of the door OT largely collision-free to the upper face VAT the lower part of the door OT , in particular for the cladding panel attached to the front MBU swing open. The axis of rotation DAO of the upper part of the door OT is in front of the overlap zone when viewed in depth UZ intended. In particular, the pivot pins are DBL of the swivel joint DGL of the upper part of the door OT outside of the movement gap SP , preferably higher than the movement gap, arranged. This leaves the separation gap on the front TS between the upper panel MBO and the lower trim panel MPU in width direction continuously open over its entire length. To a viewer, the visible gap between the upper cladding panel and the lower cladding panel appears as a straight line that extends over the entire width of the household dishwasher. This visible furniture gap preferably has a gap that largely corresponds to the gap dimensions customary in the kitchen for kitchen furniture, such as kitchen drawers.

9 shows schematically in vertical longitudinal section a further advantageous embodiment of a door arrangement designed according to the invention GT ** , in their vertical closing end position with vertical closing end position of their upper, separately pivotable door part OT is shown. Between the lower face VAT of the upper part of the door OT and the upper face EAST of the vertically running lower door part UT this door arrangement is a further advantageous embodiment of a movement gap SP with a gradient from the outside to the inside into the wash cabinet SR considered provided. The opening movement of the upper part of the door OT in its approximately horizontal end position is indicated by a movement arrow ASO indicated. The upper door part is indicated by dash-dotted lines in its horizontal opening end position and with OT * marked. The movement gap SP points away from the wash cabinet SR to the front of the door assembly GT ** considers a first horizontal gap section SPH1 , an adjoining gap section leading vertically upwards SPV and a subsequent second horizontal gap section SPH2 which is higher than the first horizontal gap section SPH1 lies. The entrance to the washroom into the movement gap SP is therefore lower than its front exit. The lower face VAT of the upper part of the door OT and the top face EAST the lower part of the door UT run largely complementary or parallel to one another in the exemplary embodiment. Through the vertical gap section SPV is such a large gradient to the wash cabinet SR provided that during a dishwashing program, while the dishwasher is in progress, spray jets are sprayed upwards, for example from a lower rotatable spray arm provided in the area of the bottom wall of the washing container, and into the horizontal gap section on the washing chamber side SPH1 meet, run back and are prevented from entering the higher-lying upper horizontal gap section SDH2 and at the front of the overall door GT ** Liquid from the front exit of the gap SP exit. Appropriately is in the vertical gap section SPV , that between the vertically downward protruding, overlapping wall section URA of the upper part of the door OT and the vertically upward, overlapping wall section ORA the lower part of the door UT lies, a seal DI ** intended. This forms a barrier against the rising of liquid and / or dirt particles in the vertical section of the movement gap. It can preferably already be at the inlet of the vertical gap section on the wash chamber side SPV be provided. Additionally or independently of this, a sealing element can also be used already in the first horizontal gap section on the wash-room side SPH1 be provided to prevent liquid droplets and / or dirt particles from rising to the front-side, higher, second horizontal gap section SPH2 to prevent from the outset if possible.

Through the (when looking at the door arrangement GT ** from outside to inside) existing gradient of the movement gap is also ensured that in the open positions of the upper door part OT , in particular also in its approximately horizontal open end position, the overlap edge protruding downward in the vertical closed end position of the upper door part URA of the upper door part, assumes an inclined position with a horizontal alignment component, in particular an exclusively horizontal alignment in the open end position of the upper door part, in which it assumes at least a front section of the upper end face EAST the lower part of the door UT , especially as here in the embodiment of 9 the entire top face EAST the lower part of the door UT , towers above and thus keeps dry and clean.

In the embodiment of 9 runs the downward protruding overlap edge URA of the upper part of the door OT essentially flush with the interior wall on the washroom side IDU the lower part of the door UT . The overlap edge protruding downwards URA of the upper part of the door OT fills a rear recess in the upper face EAST the lower part of the door UT essentially flush. Similarly, a front, upright overlap margin fills ORA the lower part of the door UT a recess in the front area of the lower end face VAT of the upper part of the door OT largely flush. The overlap edge protruding upwards ORA the lower part of the door UT thus runs largely flush with the outer wall of the upper door part OT . In generalized terms, the end faces facing one another are VAT , EAST of the upper door part and the lower door part are designed to be complementary to one another, so that they form a type of toothing in their vertical closed end position.

Of course, the mutually facing end faces of the upper door part and the lower door part can also have other geometrical shapes or contours which have a movement gap between them with at least one sloping section viewed from the outside inwards.

10 shows modified contours for this KO , KU for the faces facing each other VAT , EAST of the upper part of the door OT and the lower part of the door UT another, modified door arrangement GT *** . The upper part of the door OT and the lower door part UT have approximately the same thickness TH viewed in the depth direction. You are in the vertical closed end position of the door assembly GT *** largely aligned flush with one another with respect to their inner walls and outer walls. Viewed in longitudinal section from the side, when looking at the door arrangement GT *** from the wash cabinet SR , ie from the inside to the outside the contour KO the lower face VAT of the upper part of the door OT as well as the contour KU the upper face EAST the lower part of the door UT in each case a rise in the form of a straight line with a positive gradient angle SWI from about 45 ° to the horizontal. This results in a straight movement gap SP looking inside out at an angle SWI increases by about 45 ° from the horizontal. Is the axis of rotation DAO of the upper part of the door OT in the area of its front lower edge (viewed in the vertical closing end position) - as here in the exemplary embodiment from 9 -, or at a higher point in the area of its outer wall, or at a point in front of this, then covers the washroom-side inner door wall of the upper door part OT the upper face EAST the lower part of the door UT largely complete when the upper door part OT is pivoted into its approximately horizontal end position. In this position it is in the 10 indicated by dash-dotted lines and with OT * marked. The overhang length of the inner door wall of the upper door part on the washroom side OT then corresponds to the given thickness TH of the lower door part UT viewed in depth.

Compared to this advantageous variant, it can in particular be even more favorable if the pitch angle SWI greater than 45 ° is selected, since it is then in the vertical closed end position of the modified door arrangement GT *** for liquid droplets and / or dirt particles becomes even more difficult in the movement gap that is then set even steeper SP to ascend (viewed from the inside out). In addition, the overlap length of the facing end faces VAT , EAST of the upper part of the door OT and the lower part of the door UT larger in relation to their given thickness TH in the depth direction. As a result, in the open positions up to and including the horizontal end position of the opening of the upper door part, an even greater overhang of the upper end face can be achieved through its inner door wall on the washing chamber side VAT of the vertically fixed lower door part UT towards the wash cabinet SR to ensure.

If in particular the distance between the axis of rotation DAO of the upper part of the door OT to the lowest point of the body on the lower face VAT of the upper door part is preferably equal to or greater than the thickness TH of the lower door part UT viewed in the depth direction is at the upper front end section, then the upper door part protrudes from above in all its open positions, in particular also in its horizontal opening end position Face EAST the lower part of the door UT viewed in the depth direction completely.

If the upper door part OT and the lower door part UT on the front each with a cladding panel MBO , MBU are provided, then the above statements apply accordingly, taking into account the additional thickening that is provided by the respective cladding panel on the front side of the upper door part and lower door part.

To the upper part of the door OT as collision-free as possible in relation to the lower door part UT To be able to swing open, one or more hinge parts are expediently assigned to the upper door part and / or the lower door part in such a way that the distance between the axis of rotation of the upper door part and the lower front edge of the upper door part, including any cladding panel attached to the front, is smaller than the respective Distance between the axis of rotation of the upper door part and each location on the upper end face of the lower door part including any cladding panel applied to the front of this. In the 9 this is illustrated by the distance between the axis of rotation DAO and the lower front edge VUK the front panel, indicated by dash-dotted lines MBO of the upper part of the door OT drawn in and with A3 is designated. When the upper part of the door is swung open, the lower front edge moves VUK the front panel MBO of the upper part of the door OT on a circle of motion with the radius A3 towards the wash cabinet SR . The distance between the axis of rotation DAO and the front upper edge of the front panel, indicated by dash-dotted lines MBU the lower part of the door is also drawn in and with A4 designated.

If the cladding panels MBO , MBU of the upper door part OT and the lower part of the door UT are missing, the above statements apply accordingly, omitting the front thickening of the upper door part OT or the lower part of the door through its respective cladding panel.

To rub against the lower rear edge HUK of the upper part of the door OT when it is pivoted open at the highest point on the body of the lower crockery basket, in particular at its front-side, upwardly protruding handle HG to avoid is the distance A2 between the axis of rotation DAO and the lower trailing edge HUK of the upper part of the door OT expediently smaller than the distance A1 between the axis of rotation DAO and the highest point on the body, especially the handle protruding upwards HGB , of the lower basket UK elected. The lower basket UK in the 9 in the wash cabinet SR shown in dash-dotted lines.

11 shows in a three-dimensional representation from the side, viewed from the front, a household dishwasher, which is particularly installed in a niche between adjacent kitchen furniture KM is integrated, and one opposite the door assembly GT * the 6th - 8th Modified variant of an overall door or door arrangement designed according to the invention and pivotable about a lower, horizontal axis of rotation GT ' has, which arise from the upper separately pivotable door part OT and the lower part of the door UT composed. Just to better illustrate the construction of this door arrangement GT ' is the lower part of the door UT compared to its vertical locking position, which occurs when the upper door part is pivoted open OT actually occupies, shown slightly tilted forward. On the side edges of the lower part of the door UT the frame part protrudes RA ' upwards, the frame part from its basic structure RA the door arrangement GT * the 6th - 8th corresponds. It's in the 11 also shown tilted forward at an angle only for better illustration. In fact, it assumes a vertical closed end position and is located on the door seal on the inside of the washing container TDI on if only the front door part OT is opened in an open position. In the 11 is only to better clarify the function and construction of the door arrangement GT ' the frame part RA ' inclined towards its vertical closed end position and the upper door part OT opposite the frame part RA ' shown pivoted in an open position. In practical use, a locking mechanism expediently ensures that in an open position of the frame part RA ' the upper flap door opposite its vertical closed end position OT in the frame part RA ' is locked so that the top flap door OT cannot be opened accidentally by the user and cannot fall on him. As a result, damage to the door arrangement due to inadvertent opening of the upper flap door or even injury to the user is avoided as soon as the lower door part together with its frame part attached to it RA ' is brought into an open position with respect to its vertical closed end position. In this frame part RA ' is like the frame part RA an approximately rectangular, free cutout or opening is provided in which the upper door part is pivotably mounted as a flap door, namely forward and downward about a horizontal axis of rotation, which is preferably approximately in the area of the lower edge, in particular the front lower edge, of the upper door part or its front panel MBO is arranged. The upper part of the door OT is opposite the frame part RA ' inclined by an opening angle. As a result, the display and / or operating device is at its upper edge ABV visible and freely accessible to the user. The frame part RA ' laterally grips the left and right side cheek WLO , WRO as well as the upper one Cross member WQO the trough-shaped or trough-shaped collecting zone AO of the upper part of the door OT laterally or laterally when the upper door part is in its closed end position in the rectangular opening cutout of the frame part RA ' immersed. The frame part RA ' closes in its vertical closed end position essentially flush with the respective inner wall IW of the rinsing container SB from, ie it extends the respective inner wall, so to speak IW of the washing compartment towards the front. It has a width such that, viewed from the front, it has the loading opening thereof in a front edge zone of the washing container SU delimiting sealing bed DB in which the door seal TDI for the entire door GT ' is provided, and optionally also one on the front outer edge of the washing compartment SB attached, outer stiffening frame, and / or a piping KE in the front gap between the washing container SB and a neighboring kitchen furniture KM or countertop CAPE is provided, largely covers the front. So that the frame part RA ' a multiple function: On the one hand, it is used for pivoting mounting and for framing the upper flap door in its closed end position.
