Definitions

  • the invention relates to a household appliance, in particular in the form of a dishwasher, with a housing that provides a treatment space, which has a loading opening for access to the treatment space, with an appliance door that is pivotably mounted about a pivot axis for a fluid-tight closure of the loading opening, with a Appliance door between two end positions slidably mounted front panel and with an adjustment unit which, when the appliance door pivots about the pivot axis, moves the front panel in a positively guided manner along a guideway between the two end positions, and with a fastening device which serves to slidably arrange the front panel on the appliance door, the Fastening device has two fastening elements which are arranged one above the other in the height direction of the front panel and which each interact with a counter-contour provided on the appliance door side.
  • a domestic appliance in the configuration of a dishwasher of this type has a housing that serves as a washing compartment and provides a treatment space, also known as a washing space. This is accessible to the user via a loading opening which can be closed in a fluid-tight manner by means of a pivotably mounted appliance door.
  • the washing compartment serves to accommodate items to be cleaned, which can be crockery, cutlery and/or the like, for example.
  • a dishwasher that can be integrated into a kitchen unit typically has a furniture panel arranged on the front of the appliance door, also generally referred to as a front panel or furniture panel.
  • the front panel is used to visually match the dishwasher to the other furniture in the kitchen unit.
  • the front panel protrudes beyond the appliance door on the pivot axis side, and consequently protrudes beyond the lower edge of the appliance door. This projection of the front panel can lead to a collision of the front panel with the dishwasher base when the appliance door pivots.
  • the EP 2 329 758 B1 been proposed that the front panel is mounted on the appliance door slidably between two end positions. This previously known construction makes it possible to move the front panel in a linear or graduated guide in relation to the appliance door.
  • a fastening device is required for arranging the front panel on the appliance door.
  • This fastening device is used for the displaceable arrangement of the front panel on the appliance door, the fastening device having two fastening elements arranged one above the other in the vertical direction of the front panel to ensure that the front panel is held securely on the appliance door.
  • These fastening elements each interact with a counter-contour provided on the appliance door side.
  • a handle provided by the front panel or arranged on the front panel is provided to enable the user to actuate the appliance door, in particular to move the appliance door from a closed position that seals the loading opening in a fluid-tight manner to an open position. This is taken on the user side in the intended use case and allows the user to open the appliance door together with the front panel arranged on it as a result to pivot corresponding introduction of force. The force is introduced into the appliance door with the front panel in between.
  • the gap formation resulting from the intended use is disadvantageous in several respects. This creates a kind of “pump effect” for the user when the appliance door is opened, which creates the haptic impression of a poorly designed design. Furthermore, when the door is opened, dirt and/or dirt can get into the gap between the appliance door and the front panel, which over time leads to an unsightly clogging of the gap with the result that it no longer closes even when the appliance door is in the closed position.
  • the object of the invention to provide a household appliance which, due to its construction, enables a front panel to be securely arranged on the appliance door, while at the same time at least largely avoiding the formation of an unwanted gap between the appliance door and the front panel when the door is opened.
  • the invention proposes a generic household appliance which is characterized in that the upper fastening element in the height direction of the front panel has a hook which provides a hook mouth with an opening angle>0°.
  • the invention proposes a fastening element which has a hook.
  • This is designed in such a way that it has a hook mouth with an opening angle >0°.
  • This construction which is simple in itself, advantageously compensates for any manufacturing tolerances, while at the same time avoiding the formation of an unwanted gap between the appliance door and the front panel when the door is opened.
  • the front panel rests securely against the appliance door without a gap and there is also low-friction movement of the front panel in relation to the appliance door when the appliance door is transferred from a closed position into an open position.
  • the hook engages in the counter-contour on the appliance door.
  • a gap-free and precisely positioned fit of the front panel on the appliance door is thus guaranteed.
  • the hook lies tightly against the counter-contour, which is ensured by the opening angle of the hook mouth of > 0°.
  • the front panel moves in relation to the appliance door. This also leads to a displacement of the hook in relation to the counter-contour of the hook on the appliance door side. This causes the hook to detach from the counter-contour as the opening angle of the appliance door increases, which is favored by the > 0° opening angle of the hook mouth. From a certain opening angle of the appliance door, ie when the front panel together with the hook arranged on it has moved far enough in relation to the appliance door in the height direction of the front panel, the hook and the counter-contour on the appliance door are no longer in direct contact. A further pivoting movement of the appliance door therefore takes place with minimized friction between the front panel and the appliance door. Material wear caused by friction of the hook on the one hand and the counter-contour on the appliance door side on the other hand is thus reduced to a minimum, which ensures the long-lasting functionality of the construction according to the invention.
  • the hook threads back into the counter-contour on the appliance door side shortly before it reaches the closed position on the appliance door side.
  • this threading is made possible in a simple manner, independent of tolerances, since the hook mouth has an opening angle >0°.
  • the counter-contour on the appliance door side can therefore catch the hook just before it reaches the closed position on the appliance door side.
  • the front panel moves further down in relation to the appliance door in the vertical direction of the front panel, with which the hook also moves in relation to the counter-contour.
  • the front panel pulls itself further and further towards the appliance door as a result of a wedge-shaped interaction of hook and counterpart, so that it finally rests against the appliance door without a gap when the closed position of the appliance door is reached, since the hook is on the associated Counterpart almost stuck.
  • This arrangement of the hook on the counterpart is essentially free of play, so that opening the appliance door again prevents the formation of an unwanted gap between the front panel and the appliance door.
  • the opening angle of the hook mouth is between 5° and 20°, preferably between 10° and 15°.
  • the opening angle is preferably specified by the manufacturer.
  • readjustment can also take place in a simple manner by the hook being bent further open to enlarge the hook mouth or bent in the opposite direction to reduce the hook mouth.
  • the afore-mentioned and preferred opening angles have proven themselves in practical use, specifically independent of the front, which is why they can be used as standard to standardize an assembly unit to be carried out on site.
  • the hook has a first hook section and a second hook section, the first hook section being aligned to run in the height direction of the front panel and the second hook section being aligned to run obliquely to the first hook section, including the opening angle.
  • the hook provided according to the invention therefore has three sections, namely a first hook section, a second hook section and a connecting section which connects the two hook sections to one another.
  • the two hook sections are aligned so as to run obliquely to one another, as a result of which the opening angle provided according to the invention is formed.
  • the first Hook section is aligned to run in the vertical direction of the front panel, the first hook section therefore rests on the front panel.
  • the hook can thus be supported in a secure position on the front panel.
  • the second hook section is aligned to run obliquely to the first hook section.
  • the second hook section represents the free end of the hook, which as a result of its oblique position defines the size of the mouth opening on the input side. This is designed as a function of the counter-contour on the appliance door side, so that the hook is reliably caught by the counter-contour in the manner already described when the appliance door is moved into the closed position.
  • the two hook sections are connected to one another with the interposition of a connecting section, the connecting section being curved.
  • the curvature of the connecting section determines the opening angle of the hook mouth. This opening angle is specified by the manufacturer in the manner already described above.
  • the counter-contour interacting with the hooks on the appliance door side has a pocket into which the second hook section is immersed when the appliance door is in the closed position.
  • the hook In the closed position of the appliance door, the hook therefore engages behind the counter-contour on the appliance door, forming an undercut, in that the second hook section forming the free end of the hook dips into a pocket provided by the counter-contour.
  • the second hook section has an extent in the vertical direction of the front panel that is smaller than the travel path of the front panel between the two end positions.
  • the second hook section has an extension in the height direction of the front panel, which is dimensioned such that the second hook section is arranged outside the pocket as soon as the appliance door is moved out of its closed position by an opening angle of between 1° and 15°, preferably from between 5° and 10°.
  • an opening angle of between 1° and 15°, preferably from between 5° and 10°.
  • the overlapping of the hook according to the invention with the associated counter-contour is selected such that the hook produces the frictional connection only over a few degrees of the door opening, ie while the door is being pulled open.
  • the hook is not engaged, which advantageously ensures a smooth sliding mechanism, so that less force has to be applied by the user to move the door out of position.
  • undesirable scratching or grinding noises are avoided.
  • the opening angle provided according to the invention ie the oblique design of the hook, also allows compensation for any manufacturing tolerances and inaccurate assembly.
  • Another advantage of the slanted design of the hook is that it is easy to find the original position when closing the appliance door.
  • the hook plunges cleanly into the counter-contour or into the pocket provided by it.
  • the hook can come to rest on the counter-contour when the appliance door is closed in such a way that the front panel is pulled up against the counter-contour. This reduces the gap between the appliance door and the front panel to a minimum.
  • the hook in contrast to a mushroom head known from the prior art, can be made very narrow and only has a holding function when the appliance door is closed, advantageously only a minimum of space is lost for the design of the counter-contour on the appliance door side, so that display or control elements provided by the appliance door can be arranged particularly far outside on the appliance door for simplified inspection and operation by a user.
  • the fastening device has a coupling element that carries the two fastening elements, the fastening elements being arranged at a distance from one another by means of the coupling element, the distance between the two fastening elements being designed to correspond to the distance between the two counter-contours on the appliance door is.
  • the distance between the two fastening elements is designed to correspond to the distance between the two counter-contours on the appliance door side. It is thus not only ensured that the two fastening elements can be mounted securely in their position relative to one another. It is also ensured that during operation the intended interaction of the fastening elements with their respective counter-contours on the appliance door is guaranteed. As a result, a simplified assembly of the fastening device is made possible, while at the same time ensuring a structurally precise alignment of the fastening elements, both in their relative position to one another and in their operative connection with the counter-contours on the appliance door.

  • the further fastening element is arranged at a distance specified by the coupling element from the other two fastening elements.
  • This structural measure of the coupling element also advantageously ensures that the distance is maintained. In their relative position to one another, all of the fastening elements are at a distance from one another that is predetermined by the coupling element, so that a positionally accurate and secure arrangement of all fastening elements on the front panel is ensured.
  • the further fastening element is screwed to the coupling element.
  • a one-piece configuration of the coupling element and further fastening element can also be provided.
  • the arrangement of the further fastening element on the coupling element by means of a screw connection has the advantage that the further coupling element can be designed independently of the coupling element in terms of material selection and geometric shape.
  • the further coupling element in the manner of a mushroom head.

  • the positioning aid 31 thus ensures that the relative distance between the two coupling links 25 and 26 is defined in the width direction 29 of the front panel 8 .
  • the positioning aid serves to position the coupling links 25 and 26 precisely in their respective spacing from the associated edge of the front panel 8 .
  • the positioning aid 31 has the center marking 32 already explained above, which allows the coupling links 25 and 26 to be aligned centrally.
  • the positioning aid 31 is in a form-fitting operative connection with one coupling link 25 at one end and with the other coupling link 26 at the other end. like this in particular Figure 39 reveals.
  • the use of only one positioning aid 31 is sufficient. This can be used to align the coupling links 25 and 26 at one end in a first assembly step. As soon as this has been done, the positioning aid 31 can be removed from the coupling links 25 and 26 as intended and used to align the coupling links 25 and 26 at the other end. In a further assembly step, the positioning aid 31 is then to be removed completely, with the coupling links 25 and 26 being positioned accurately and securely overall due to their alignment first at one end and then at the other end are aligned and arranged relative to the front panel 8 .
  • a first mounting mark 59 is provided, such as 26 shows. This is provided on a front side 7 of the appliance door 6 facing the front panel 8 in the final assembled state.
  • the first assembly mark 59 is accessible for assembly when the appliance door 6 is closed, even when the dishwasher 1 has already assumed its final set-up position, i.e. has been placed in the niche of a kitchen unit provided for this purpose.
  • This first assembly mark 59 which is accessible on the assembly side when the appliance door 6 is closed, serves to measure a reference distance 60 in the vertical direction 21 of the appliance door 6, as is the case in the exemplary embodiment shown 26 between the first marking 59 and a skirting board 61 results.
  • This dimension determined by means of the first mounting mark 59 can be transferred to the back 19 of the front panel 8 . This is done, for example, by drawing in a corresponding auxiliary line 27.
  • the auxiliary line 27 taken over by tearing off on the back 19 of the front panel 8 is used to align the fastening device 20 provided for arranging the front panel 8 on the appliance door 6, namely in the vertical direction 21 of the front panel 8.
  • the first assembly marking 59 represents and thus also the first Auxiliary line 27 shows the position of the front panel 8 in its first end position, specifically in its end position, which the front panel 8 assumes when the appliance door 6 is closed.
  • the auxiliary line 27 is used to align the fastening device 20 by the coupling links 25 and 26 being placed against the auxiliary lines 27 with their lower edge in the vertical direction 21 of the front panel 8 .
  • auxiliary line 27 previously shown on the back of the front panel 8 is also applied to a narrow side of the front panel 8, as shown in FIG 29 reveals. In a side view, this auxiliary line 27 can be seen with the washing compartment door open, how this also from the illustration Figure 35 results.
  • a second mounting mark 63 is provided, specifically one that is arranged in the vertical direction 21 of the front panel 8 above the first mounting mark 59, like that Figures 31 and 32 reveal.
  • the second assembly marking 63 is provided by a narrow side 65 of the appliance door 6 .
  • This second mounting mark 63 represents the position of the front panel 8 in its second end position, which is reached when the appliance door 6 is in its fully open position. Because due to the movable arrangement of the front panel 8 on the appliance door 6, the front panel 8 moves upwards in the vertical direction 21 of the front panel 8 when the appliance door 6 is transferred from the closed position to the fully open position, as can also be seen from a synopsis of the Figures 36 to 38 results.
  • the auxiliary line 27 previously drawn on the narrow side of the front panel 8 and the second installation mark 63 on the associated narrow side 65 of the appliance door 6 must overlap for precise positioning of the front panel 8, as can be seen, for example, from Figures 35 and 38 results. Because the distance between the two assembly markings 59 and 63 corresponds to the possible travel path of the front panel 8 between the first end position and the second end position.
  • a third assembly mark 64 is provided, which corresponds to the first assembly mark 59 and is provided by the narrow side 65 of the appliance door 6 bearing the second assembly mark 63 .
  • the first assembly marking 59 represents the position of the front panel 8 in its first end position, i.e. with the appliance door 6 closed.
  • the appliance door 6 must therefore be closed to take over a distance measurement, which is why the first assembly marking 59 is also designed on the front of the appliance door 6 for accessibility .
  • the third assembly mark 64 is provided, which corresponds to the first assembly mark 59, but is not arranged on the front side 7 of the appliance door 6, but on a narrow side 65 adjoining the front side 7.
  • the narrow side 65 of the appliance door 6 also has a mounting opening 66, such as the Figures 34 and 35 reveal.
  • the purpose of the mounting opening 66 is to secure a front panel 8 arranged and aligned on the appliance door 6 in its position. Provision is therefore made for the assembly opening 66 to be designed in such a way that a fastening element 23 provided by the fastening device 20 and/or a counter-contour 46 which interacts therewith and is provided on the appliance door side is or are accessible. It is thus permitted to leave the dishwasher 1 in the niche provided for this purpose in the kitchen unit also for securing the position of the front panel 8 . It is only necessary to move the appliance door 6 into an open position in such a way that the assembly opening 66 is accessible on the assembly side. Then it is already allowed to reach the fastening element 23 and/or the counter-contour 46 for securing the position of the front panel 8 .
  • the height direction 21 of the front panel 8 upper fastener 22 is designed as a hook 74, such as a synopsis of the Figures 6 to 10 reveals.
  • the hook 74 is formed in one piece with the coupling member 25 and has two hook sections 75 and 76 which are connected to one another by means of a connecting section 77 of curved design.
  • the two hook sections 75 and 76 form a hook mouth 52 between them, the opening angle ⁇ being >0°, as in particular 10 reveals.
  • the opening angle ⁇ >0° is achieved in that the free hook section 75 is aligned to run obliquely to the other hook section 76, as is also the case in particular 10 reveals.
  • This construction which is simple in itself, advantageously compensates for any manufacturing tolerances, while at the same time avoiding the formation of an unwanted gap between the appliance door 6 and the front panel 8 when the door is opened.
  • the front panel 8 is in the locked position of the appliance door 6 in a secure position and without a gap on the appliance door 6 and there is also a low-friction process of the front panel 8 in relation to the appliance door 6 when the appliance door 6 is transferred from a closed position into the open position.
  • the hook 74 engages in the counter-contour 34 on the appliance door, like this one 8 reveals. A gap-free and precisely positioned seat of the front panel 8 on the appliance door 6 is thus ensured.
  • the hook 74 rests tautly against the counter-contour, which is ensured due to the opening angle of the hook mouth 52 of ⁇ >0°.
  • the front panel 8 moves in relation to the appliance door 6. This also leads to a movement of the hook 74 in relation to the counter-contour 34 on the appliance door. which is favored by the >0° formed opening angle ⁇ of the hook mouth 52. From a certain opening angle of the appliance door 6, i.e. when the front panel 8 together with the hook 74 arranged on it has moved far enough in relation to the appliance door 6 in the vertical direction 21 of the front panel 8, the hook 74 and the counter-contour 34 on the appliance door are no longer in direct contact, e.g 10 reveals. A further pivoting movement of the appliance door 6 therefore takes place with minimized friction between the front panel 8 and the appliance door 6.
  • the lower in the vertical direction 21 of the front panel 8 fastener 23 is also designed as a hook 38, as a synopsis of Figures 14 to 25 reveals.
  • the hook 38 provides a hook mouth 41 , the hook 38 having a cam 48 tapering the mouth opening 49 on the mouth entrance side.
  • This configuration makes it possible to arrange the lower fastening element 23 in the vertical direction 21 of the front panel 8 in a simple manner on the counter-contour 46 on the appliance door side. For this purpose it is only necessary to position the front panel 8 in the vertical direction 21 in such a way that the hook 38 is positioned above the counter-contour 46 on the appliance door side. Then the front panel 8 is to be guided downwards in the direction of the weight force acting on it, as a result of which the hook 38 is operatively connected to the associated counter-contour 46 occurs and locked with this.
  • the hook 38 On the mouth entrance side, the hook 38 has a cam 48 that narrows the mouth opening 49 .
  • This cam 48 essentially fulfills two functions. On the one hand, a certain amount of force is required to overcome the resistance caused by the cam 48 when the hook 38 is inserted into the counter-contour 46 . Overcoming this resistance is perceived by an assembly person during assembly, whereby the cam 48 provides quasi feedback for the assembly person that the hook is now arranged on the counterpart 46 as intended.
  • the cam 48 ensures that a mounted front panel 8 can unintentionally slip out of the counter-contour 46 before securing the position.
  • the cam 48 shows, as shown in particular by the illustration 14 can be seen, an insertion bevel 50 on the one hand and a limiting bevel 51 on the other.
  • the cam is not designed to be axially symmetrical, because the insertion bevel 50 is designed to be less steep than the limiting bevel 51 . This takes account of the fact that the insertion slope 50 is intended to serve as an insertion aid, but the limiting slope 51 serves as a stop.
  • the hook 38 has a first hook portion 39 and a second hook portion 40, which are spaced apart from each other to form the hook mouth 41.
  • the edges 42 and 43 of the hook sections 39 and 40 facing the hook mouth 41 are equipped with a latching contour 33 .
  • Each latching contour 33 has pockets 44 and teeth 45 arranged alternately in the height direction of a latching edge Figures 19 to 21 reveal.
  • the clamping piece 46 interacts with a guide body 47, with the hook 38 between the clamping piece 46 and the guide body 47 is arranged like this the figures 19 and 20 reveal.
  • the clamping piece 46 has a web 54 and a stop 55.
  • the hook 38 is placed on the web 54, as shown in FIG 20 shows.
  • the web 54 is equipped with the stop 55 at one end.
  • This stop 55 ensures that the hook 38 cannot slide down one end of the web 54 in the longitudinal direction of the web 54 .
  • the stop 25 serves as an abutment between which the hook 38 is clamped in combination with the guide body 57 in the final assembled state.
  • the stop 55 also serves to form a chamfer 57 in the transition area between the web 54 and the stop 55 .
  • the latching contour 33 of the associated edge on the hook side engages in this bevel 57 .
  • the guide body 47 is carried by a movably mounted rail 53 and is part of the adjusting unit, by means of which the front panel 8 is positively guided along a guideway between the two end positions when the appliance door 6 pivots about the pivot axis.
  • the guide body 57 moves in the vertical direction 21 of the front panel 8 relative to the appliance door 6, which also results in a movement of the front panel 8 in relation to the appliance door 6.
  • the guide body 47 has a projection 58 corresponding to the chamfer 57 formed on the clamping piece 46, which cooperates with the pockets 44 and teeth 45 of the associated peripheral edge of the hook 38.
  • the latching contour 33 of the hook 38 is thus dug into the chamfer 57 of the clamping piece 46 on the one hand and into the projection 58 of the guide body 57 on the other hand, giving a frictional and form fit on both sides.
  • the digging of the locking contour 33 in the chamfer 57 or the projection 48 takes place as a result of a movement of the clamping piece 46 in the direction of movement 56, ie in the direction of the guide body 47, as can be seen from the illustration in particular 20 results.
  • the above construction of the hook 38 allows a continuous adjustment of the hook 38 in relation to the guide body 47, as is the case in particular Figures 16 and 17 reveal. This advantageously opens up the possibility of fine adjustment, with the front panel 8 being able to be fixed in position in this position when the desired end position is reached.
  • the fastening device 20 Since the coupling members 25 and 26 of the fastening device 20 have a plurality of through-holes 30 for screwing to the front panel 8, the fastening device 20 is also suitable for divided front panels 8, which are composed of a plurality of sections 69, such as Figure 41 reveals.
