Abstract

The dishwasher (1) has a door (5) arranged at the front side of loading opening (3) used for accessing the washing container (4), and a light-transmissive portion (16) of the inner wall (8) of the door, which is made of light-permeable material. The light-transmissive portion has one or more functional elements (15) such as display elements and/or lighting elements provided in the surface of the inner wall of door. The inner wall of the door is made of translucent or transparent non-metallic material such as glass and/or plastic.

Description

The invention relates to a dishwashing machine, in particular a domestic dishwasher, with a washing container accessible via a front loading opening that can be closed by a door. Usually, a door of conventional dishwashers comprises two sheet metal shells, namely an outer shell or an outer wall and an inner shell or inner wall connected thereto. The outside of the inner shell forms the inner wall side of the door.

The object of the invention is to propose a dishwasher, in particular a domestic dishwasher, with an alternatively designed door.

This object is achieved in a dishwasher of the type mentioned in that at least a portion of the inner wall of the door is translucent, in particular made of a translucent material. This allows a variety of advantageous design options for the inner wall of the door.

For example, one or more functional elements, in particular display elements or display units, lighting elements, preferably light sources, and / or operating elements or operating units can be accommodated behind the respective translucent subregion of the inner wall of the door, covered by this in the interior of the door and thus protected , At the same time, the respective functional element remains visible or perceptible to a user or, in particular, can be made visible or perceptible with the aid of one or more light sources associated with the respective functional element. By this construction, the display and / or ease of use of the dishwasher for a user can be significantly improved compared to previous dishwashers that provide display and / or controls on a front panel in the top, outside front of the door or on the top edge of the door. Because by the accommodation of one or more functional elements such as display, lighting and / or controls in the Interior of the door behind one or more of translucent material existing portions of the inner wall of the door, these are when the door is open, in particular in their approximately horizontal Offenendstellung (fully open state), loaded in the interior of the washing compartment of the dishwasher with items to be cleaned or cleaned items unloaded, accessible, in particular visible or perceptible. Thus, in the open position, in particular at approximately horizontal full open position of the door, for example, a display unit, which is arranged behind a formed of translucent material portion of the inner wall of the door, easily read, and / or an operating unit behind the formed of translucent material portion of the inner wall the door is arranged to be easily operated. It is therefore no longer necessary in the construction of the dishwasher according to the invention, in contrast to conventional dishwashers to close the door to ever display elements on the front panel or top edge of the door see and / or controls on the front panel or top edge of the door see and operate to be able to. If one or more lighting elements, in particular light sources such as LEDs, for example, are arranged behind the part of the inner wall of the door made of light-transmitting material, practical lighting is provided. This makes it possible in particular to illuminate a moved out to the fully open door basket with the placed on this dishes. Thus, for example, after the end of a dishwashing program, the cleanliness of the rinsed items to be washed can be checked directly and conveniently.

In general terms, the fact that one or more functional elements, in particular display elements, lighting elements, and / or operating elements, etc., are accommodated behind the respective translucent subregion of the inner wall of the door in the interior of the door, thus improves the ergonomics and provide an improved man-machine interface in handling the dishwasher. For now it is possible, among other things, that in particular when the door is opened by the user anyway, in particular brought to their approximately horizontal Offenendstellung to adjust, for example, to be cleaned dishes in the baskets of the dishwasher, detergent powder and / or rinse aid in at least one addition device the inner wall of the open door, and / or salt in at least one brine tank from the interior of the Rinse container ago refill adapted to about the same working level, especially at about the same height range at the same time verifies the operating state of the dishwasher, a dishwasher can be selected and started. An awkward change from the filling of the washing container with items to be washed, detergent, rinse aid, and / or regenerating in a completely different area zone, especially altitude for reading the display unit and / or operating the control unit, as previously required by closing the door in conventional dishwashers was to bring the display unit and / or control unit on the front panel of the door or top of the door in the field of view of the operator, now eliminated in an advantageous manner.

In particular, it may be advantageous if the respective light-transmissive area provides a display on the surface of the inner wall of the door. This results in comfortable display options, in particular for operating functions and / or operating conditions of the dishwasher, when the door is open, in particular brought into their approximately horizontal Offenendstellung or full open position.

According to an expedient development of the invention, the respective translucent region can be formed by a translucent or transparent wall region, in particular by a translucent or transparent cover plate, preferably by a glass and / or plastic plate, in the inner wall of the door. This allows a structurally simple and safe, especially against soapy water protected housing of one or more functional elements, such. Display, lighting, and / or controls, in the inner wall of the door, which are still visible or perceptible to a user when the door is open, in particular fully open. In this case, glass is advantageously largely rinsing-resistant.

According to a particularly expedient development of the invention, at least the area of the inner wall that comes into contact with the interior of the washing container (in the closing end position of the door) and in the dishwashing mode of the dishwasher can be acted upon by flushing liquid from one or more spraying units, in particular the entire inner wall formed by a, at least one translucent portion having cover plate. This cover plate is expediently attached to the inside of the door, in particular fixed. At least in the closed state of the door to the interior of the washing container facing, coming into contact with this region of the door is thus formed from one, ie single or single cover plate having at least one translucent portion. With such a door initially open many attractive design options, for example in terms of color and / or in terms of the surface design of the inside of the door. A further advantage results from the fact that relatively inexpensive materials can be used to create surfaces that withstand the conditions of the cleaning process, eg high temperatures, cleaning agents and / or corrosive influences.

It is especially advantageous if this cover plate, which replaces the inner wall of the door at least in the area coming into contact with the interior of the washing container in the closing end position of the door, consists of a translucent, ie translucent to transparent, material. Such a cover plate offers the possibility of the inside of the door for one or more functional elements such. for optical display devices, lighting elements, control devices, and / or controls. Conveniently, the respective one or more functional elements are disposed between the cover plate and the door body, i. housed in the interior of the door between the inner wall of the door-forming cover plate and the outer wall or outer shell of the door. However, due to the translucency of the cover plate, in any case with optical display elements and / or lighting elements, there are no element-receiving apertures in the preferably fully closed, i.e. Uninterrupted cover plate required so that no joints are present, which would be expensive to seal. A cover plate constructed in this way thus covers at least the surface area of the door which comes into contact with the interior of the washing container (viewed in its closing end position) preferably hermetically tight.

A particularly secure hermetic seal of the door on its facing the interior of the washing compartment wall area can then be provided when the cover plate, the entire inner wall surface of the door, the washing compartment (in the Closing final position of the door) facing, largely covers the entire surface, ie the inner wall of the door largely completely replaced. In particular, it may be expedient if the cover plate also provides an edge surround for the door, which partially or completely bridges the gap between the outer wall and the inner wall of the door and extends in the depth direction of the door. For this purpose, it may be expedient if the cover plate is designed as a wall shell, which has sections or around the outer boundary of its inner wall surface to the outer wall of the door, especially in the final closing position of the door forward, projecting edge as a lateral border of the door.

The respective cover plate, which as explained above forms either a partial surface or that surface of the inner wall of the door, which comes in Schließende position of the door with the interior of the washing compartment in contact, or even the total area of the entire inner wall forms, in the final closed position of the door as a whole Rinsing container (including its front-mounted door sealing bed and front reinforcing elements) faces, may preferably be made of a translucent, preferably non-metallic material, in particular glass, plastic or a composite of these two materials. In this case, glass is advantageously largely rinsing-resistant. It can be formed at least in one or more desired light transmission areas or overall translucent to transparent, ie partially translucent to transparent to the image or view. If, however, possibly a largely complete transparency of the cover plate for optical reasons is not desirable because, for example, structural elements of the door body would be visible, it may be particularly useful if a cover plate with appropriate translucency, ie only partial light transmission is used. In a preferred embodiment, it may be provided for this purpose, for example, to provide the translucent cover plate inside and / or outside with at least one coating which has a lower light transmission than the material from which the cover plate consists. For example, the outer wall surface and / or the inner wall surface of the cover plate can be provided with at least one particle layer, in particular color particle layer or metal layer, and / or with at least one film, in particular color or metallized film. The outer wall surface and / or the inner wall surface of the cover plate may be provided, for example, with at least one particle layer, in particular color particle layer or metal layer, steamed, coated or printed, and / or with at least one film, in particular color or metallized film, be glued. Possibly. can be made opaque by mixing or admixing of light scattering and / or light reflecting particles in the translucent material of the cover in the manufacturing process, the cover plate as a purely transparent material, so that eg door components in the interior of the door behind the cover plate not visible from the outside or are visible, but the functional components such as display elements, controls, etc ..., are visible from outside or can be made visible when watching. Thus, the functional components such as display elements, controls, etc ..., possibly with the help of additional lighting by one or more light sources, which sit behind the cover plate, and radiate light from the inside out and / or by lighting from outside with outside into the inside of the door through the cover plate directed light rays at least one, preferably mounted on the washing water light source, made perceptible to an operator.

In particular, it may be expedient if the respective cover plate only in one or more desired light transmission areas, preferably light exit and / or light entry areas for light from behind her in the interior of the door accommodated one or more functional elements such as lighting elements, in particular light sources, or the like outlet and / or for light that strikes the outside of the respective light passage area from at least one light source is more permeable than in the other areas of the cover plate, so that the one or more functional elements behind the respective light passage point from the outside are visible or can be made visible. A light source which provides for external illumination of the respective light passage region of the cover plate, for example, on the underside of the upper, the interior of the washing container partially enclosing, front edge portion of the washing compartment mounted and radiate rays of light down when the door is open, especially in an approximately horizontal opening end position is brought. The cover plate is generally expressed in an advantageous embodiment of one or more light transmission areas so translucent or transparent acting than in their other areas formed to leave behind arranged one or more functional elements visible.

To one or more functional elements, such. Lighting elements, display elements, operating elements or the like, which are visible from the outside behind the one or more desired light passage areas of the respective, the inner wall of the door partially or completely forming cover plate, the respective desired light passage area may expediently have a thinner wall thickness than in the other wall areas , By such a wall thickness reduction or wall thickness weakening in the respective desired light passage area is from e.g. the light emitted by the respective light source of the respective functional element behind the cover plate reflected less toward the interior of the door back than in the other wall portions of the door, so that it can better penetrate the wall of the cover plate in the desired light exit area. Additionally or independently thereof, it may be expedient if the cover plate has an inner and / or outer coating in the respectively desired light passage region, which has a lower shielding effect or blocking effect against light emission and / or light entry than in its remaining regions. Outside the respectively desired light passage region of this translucent cover plate, it may possibly be provided on the inside and / or outside with at least one substantially opaque coating. In particular, it may be expedient according to a further advantageous embodiment variant if a light-penetration-inhibiting or light-barrier-blocking coating is omitted in the one or more light passage regions of the cover plate. There remains the translucent to transparent material of the cover so uncoated.

In this way, one and the same cover plate can be used for a variety of different design variants, wherein at least one of the respective design variant corresponding, i. assigned specific coating applied, for example, sprayed on, painted and / or printed.

A cover plate of the various types described above completely covers one or more functional elements arranged behind it, wherein, however, eg one or more functional elements, in particular light-emitting functional elements preferably remain visible or their light can penetrate the cover plate into one or more desired light transmission areas.

According to an advantageous development of the invention, a subregion formed from a light-transmissive material and the one or more functional elements arranged behind it in the interior of the door, in particular a group of functional elements which are arranged in spatial proximity to one another, can be a functional field, e.g. form a control panel, a display panel, a lighting field or a multifunctional field comprising said functions. In the case of a control panel or controls in general, elements covered by the cover plate, e.g. Switching elements present, which can be actuated by touching the cover plate with about a finger of the hand due to, for example, optical or capacitive effects. A functional field may e.g. be deposited by a different, for example, color different coating of the remaining surface or coating of the cover plate.

In order to facilitate the operation and readability of a partial region, in particular a functional field, formed of a light-transmitting material, this is preferably arranged in the central region or particularly advantageously in the upper third of the door and, in particular, centrally. As a result, the functional field can be read and / or operated by a user at an early stage, even at an already small opening angle of the door and even more so in the open end position of the door, in which it is aligned approximately horizontally. On the inside of the door is usually a feed device for cleaning agents. This is preferably provided in the upper third of the door. In the case of a translucent to transparent cover plate forming the inner wall of the door, at least in the region of the feed device, in particular the entire inner wall, it therefore expediently has a breakthrough which accommodates the feed device in this case. This breakthrough or the feed device passed through it can expediently be arranged at least partially within the functional field. However, the addition device is not part of the functional field. In particular, if the one or more functional units provided for the operation of the dishwasher, such as display elements, lighting elements, and / or operating elements and / or feed device are arranged approximately in the same local area, the ergonomics in the operation or handling of the dishwasher can be improved.

A cover plate may finally have a receiving trough according to an advantageous embodiment of the invention. The cover plate has, in particular, a region which is recessed in the direction of the interior of the door and recessed in the direction of its outer wall, forming a receiving trough. This receiving trough is expediently dimensioned such that it largely absorbs a receiving basket which has been moved out of the interior of the washing container in the approximately horizontal open end position of the door. Thus, for example, from items to be washed with dishes when the door drips liquid can thus not flow off to the side, since it is collected in the receiving trough and can flow back when closing the door in the washing.

Finally, it may possibly be advantageous if the respective partial region formed of a translucent material is provided in such an outer zone of the wall surface of the inner wall of the door, which in the closing end position of the door faces the washing compartment, but outside with the interior of the washing compartment is in contact coming wall surface of the inner wall. Such positioned, formed of a translucent material portion is largely splash-proof, always freely accessible and / or visible, which improves the ease of use.

Other advantageous developments of the invention are given in the dependent claims.

The above-described and / or reproduced in the subclaims advantageous embodiments and developments of the invention can thereby - except, for example. in the case of clear dependencies or incompatible alternatives - individually or in any combination with each other.

The invention and its advantageous embodiments and further developments and advantages thereof are explained in more detail below with reference to drawings.

Elements with the same function and mode of action are in the FIGS. 1 with 3 each provided with the same reference numerals. In the figures, only those components of a dishwasher are provided with reference numerals and explained which are necessary for the understanding of the invention. It goes without saying that the dishwasher according to the invention can comprise further parts and assemblies.

Fig. 1 shows a domestic dishwasher 1, which comprises a housing 2, a arranged in the housing, a front loading opening 3 having rinsing 4 and a pivotable at a lower end about a horizontal axis door 5, which closes the loading opening 3 comprises. Possibly. can the outer casing 2. - As customary in built-in dishwashers - be partially or completely omitted. In the interior 6 of the washing container 4, a receiving device for items to be washed in the form of two superposed receiving baskets 7 is arranged. Furthermore, in the washing container 4, for example, a spray arms having spraying device 21 is present, which is only indicated by dash-dotted lines.

The inside of the door 5 is here completely formed in the embodiment of a cover plate 8, wherein the cover plate 8 extends substantially over the entire width and length of the door. It is also conceivable, however, that only the area of the door 5 which is in contact or contact with the interior 6 of the washing container 4 when the door is closed is covered by the cover plate 8.

The cover plate 8 is made of a translucent material, in particular non-metallic material such as glass or plastic .. The cover 8 may also be a composite of glass and plastic. Due to the translucency, one or more functional elements can be arranged behind the cover plate 8, ie on its side facing away from the washing container 4 in the closed state side, which are visible because of the translucency or translucency of the cover 8, especially when the door is open approximately horizontally is in the direction of view from top to bottom. However, the translucency of the cover plate 8 is so far reduced that a view of her covered construction parts, such as an outer shell 9 of the door 5 and / or reinforcing elements such as ribs, webs, etc .. In the interior of the door is prevented. This can be accomplished, for example, by the fact that the material of the cover plate 8, ie the glass and / or the plastic, is colored. Preferably, however, additionally or independently thereof, the light transmittance of the cover plate 8 is reduced by its inner side 10 (FIG. Fig. 2 ) and / or its outside 13 ( Fig. 3 ) is provided with a coating 14, which has a lower light transmittance, than the material of the cover plate 8 itself. Also in the case of a coating 14, the translucency of the cover plate 8 can be reduced in the above-described manner. As functional elements are controls, display elements and / or lighting elements in question. In the latter two cases, the functional elements comprise, for example, light-emitting diodes. The controls are expediently, since they are arranged behind the cover plate 8 and thus are not directly accessible, designed so that they can be actuated or switched upon contact with the outer side 13 of the cover plate 8 or a coating 14 thereon. For example, non-contact capacitive proximity switches come into question here. A functional element 15 configured as an operating element may be equipped with a light-emitting diode in order to increase its visibility.

As in Fig. 2 can be seen, the functional elements or parts 15 are mounted on the inside of the outer shell 9 of the door 5, for example on a connected to the inner wall surface of the outer shell 9 carrier 161. The functional elements 15 are conveniently summarized locally, so that they form a functional field 16 , This functional field 16 can be optically highlighted, for example by being provided with a coating 14a that differs optically from the remaining coating 14b of the cover plate 8, for example a higher light transmission having. Different coatings of the type mentioned can be prepared in a simple manner, in particular by means of a printing process, for example the screen printing process, vapor deposition or coating process.

The functional elements 15 and the functional field 16 of the cover plate 8 covering them are arranged centrally in the upper third in the exemplary embodiment. In this area, there is also an adding device 17 for cleaning agent, which is integrated in the functional field 16, which is designed, for example, as a rectangle. In the cover plate 8 there is an opening 18 for this purpose, in which the feed device 17 is inserted, i. The addition device is not part of the functional field 16. An arrangement of the functional field 16 in the central region of the inner wall of the door may also be expedient, since there usually free space is available, which is easily visible.

The cover plate may possibly be configured level, which is in the located below the dashed line 20 door area in Fig. 1 is indicated. Preferably, however, the cover plate 8 is recessed to form a receiving trough 19 in a trough-shaped manner (see Fig. 3 and door area above the line 20 in Fig. 1 ) educated. For example, if liquid 7 drips onto the cover plate 8 when a receiving basket 7 is pulled out of the washing container 4, it is retained in the receiving recess 19.

In summary, therefore, at least the area of the inner wall which comes into contact with the interior 6 of the washing container 4 in the closing end position of the door 5 and can be acted upon by the dishwasher during flushing operation, in particular the entire inner wall, of the door 5 is provided with at least one translucent portion 16 Cover plate 8 is formed. In an advantageous modification to the above embodiment of the FIGS. 1 with 3, it may be advantageous if the cover plate 8 is designed to be more translucent in the area of the functional field 16 as in their other areas. For example, it may be provided outside the functional field 16 with a light-diffusing and / or light-reflecting, in particular opaque, coating on its underside and / or upper side, while it is uncoated in the functional field 16.

Possibly. it may be sufficient according to a further advantageous embodiment, if only the functional field 16 in the inner wall of the door 5 forms a portion of a translucent material. For this purpose, it may be useful if a breakthrough or a recess in the inner wall of a, in particular made of metal, preferably stainless steel, conventionally constructed door is provided for the function field 16, and in this breakthrough a translucent or transparent cover plate, preferably a glass and / or plastic plate, in particular flush-mounted, is used. Generally speaking, therefore, only one or more singular subregions, such as here 16 of the inner wall of the door, are formed from a translucent material. One or more functional elements 15, in particular display elements and / or illumination elements, preferably light sources, and / or operating elements are arranged behind the respective, translucent subregion, such as 16 of the inner wall of the door, covered by this in the interior of the door 5. Thus, a functional field is provided. It can be advantageous, in particular, when the translucent subarea 16 provides a display and / or a lighting field on the surface of the inner wall of the door. In summary, therefore, in this modified embodiment, only one or more portions of the cover, which forms the Türinnenwandung, from a translucent, ie transluszentem to transparent material, in particular glass or plastic, formed while the remaining wall surfaces of the inner wall of the door of an opaque material such as metal are made. Possibly. it may be expedient according to a further advantageous modification, when the respective formed of a transparent material portion is provided in such an outer zone of the wall surface of the inner wall of the door, which faces the washing in the final closing position of the door, but outside of the interior the rinsing container coming into contact wall surface of the inner wall and thus largely unaffected by rinsing liquid and therefore remains largely dry. In the FIG. 1 This is, for example, an outer edge zone RZ along the respective longitudinal side of the door, which lies outside the edges of the trough 19. In the vertical closing end position of the door, the edge zone RZ preferably comes into contact with a door seal, which is provided in a sealing bed at the front edge region DB of the washing compartment 4. The gasket bed is in the FIG. 1 have been omitted for the sake of clarity of drawing. It revolves around the loading opening 3 along the upper, extending in the width direction of the washing compartment Randzonenabschnitt of the washing and the two lateral, extending in the height direction of the washing container edge zone sections of the washing, ie the sealing bed summarizes the loading opening in a peat shape. It is preferably attached to a reinforcing element of corresponding shape, which is fastened to the upper and the two lateral edge zone sections of the washing container in the region of the loading opening. In the outer edge zone RZ a formed of a light-transmissive material portion 22 is provided, which in the FIG. 1 indicated by dash-dotted lines. Behind its translucent trained cover plate one or more functional elements such as display elements and / or lighting elements may be provided. Due to the fact that one or more subregions formed in each case from a light-permeable material are provided in at least one outer zone of the wall surface of the inner wall of the door, which in the closing end position of the door lies outside the wall surface of the inner wall which comes into contact with the interior of the washing compartment, an or several functional elements such as display elements, lighting elements, controls behind the respective translucent part, in particular its translucent cover plate are largely splash-proof housed. In addition, this outer zone is outside the path of movement for the lower receiving basket 7, when it is pulled out of the interior 6 of the washing container 4 on the inner wall of the door 5 in its approximately horizontal Offenendstellung and parked in the receiving trough 19. As a result, the particular region formed of translucent material such as 22 in this outer zone such as RZ always remains freely accessible and / or visible and the one or more arranged behind the cover plate in the interior of the door functional elements perceptible and / or operable. The portion formed of translucent material, such as e.g. 22 is therefore not covered by the retracted receiving basket 7, but is exposed and / or accessible. In this way, a particularly comfortable display, lighting and / or operating option is provided from the inside of the door, when it is brought into an open position, in particular in its approximately horizontal Offenendstellung.
