Definitions

  • the invention relates to a household appliance, having a treatment room that can be closed by means of a front door, the at least one side wall of which has an opening for the use of a lamp, and at least one lamp for illuminating the treatment room, which protrudes through the opening.
  • the invention is particularly advantageously applicable to refrigerators, in particular refrigerators.
  • DE 10 2012 205 766 A1 discloses a container for a refrigeration device, with a container element, the container element having a flat area with a light-permeable section.
  • the container element has a luminous means which is designed to illuminate the transparent section.
  • EP 2 594 880 A2 reveals a refrigerator.
  • the refrigerator has an inner case housed in an outer case, a recess formed in the inner case and having a predetermined depth, a light source received in the recess, and a cover received in the recess and surrounding the light source.
  • the light source can direct light onto a rear part of the inner housing in order to illuminate a corresponding compartment formed there.
  • the cover may have an extension that extends substantially parallel to the inner housing and is received in the recess to prevent light emitted from the light source from being directed onto a front portion of the inner housing.
  • the fact that the overlapping area covers at least one edge section can also be expressed in such a way that the light-permeable plate, starting from the opening of the light shaft, extends over this edge section.
  • the front surface in connection with the shape of the edge flattening behind it in a rearward direction has the further advantage that a user is not or not noticeably dazzled by the light emerging from the lamp.
  • the overlapping area is designed for two-dimensional light extraction can include that the overlapping area has scattering centers (e.g. particles or air inclusions) and / or its surface facing the treatment room is roughened or structured for light extraction. In particular, it can be effected in this way that light rays running in the overlap area fall onto the surface facing the treatment room at such a small angle of incidence that they can be coupled out of the overlap area into the treatment room.
  • scattering centers e.g. particles or air inclusions
  • the household appliance is a refrigeration device (e.g. a refrigerator or a freezer).
  • the treatment space then corresponds to a usable space or cooling space of the refrigeration device that can be cooled.
  • the home appliance is not limited to this and may be a cooking appliance, a dishwasher, etc., for example.
  • the treatment room is delimited by a wall (in the case of a furnace also referred to as a muffle or furnace pipe) and on the front by the closed door.
  • a side wall can be understood to mean in particular a left-hand side wall, right-hand side wall, ceiling and / or rear wall of the wall or of the treatment room when looking through a loading opening that can be closed by means of the door.
  • One or more of the side walls can each have one or more openings for respective lights. It is an embodiment that at least one lamp is arranged on a ceiling of the treatment room.
  • a lamp protrudes through the opening includes that it is arranged partly inside the treatment room and partly outside the treatment room.
  • the edge is located inside the treatment room, while the light shaft is partly inside the treatment room and partly outside the treatment room is arranged.
  • the light shaft protrudes vertically through the opening.
  • the opaque material can be, for example, plastic, enameled metal, etc.
  • the fact that the edge surrounds the light shaft laterally can be implemented in such a way that the area of the first component located in the treatment room is shell-shaped, has a central recess and the light shaft attaches to the recess in the direction of the opening.
  • the central recess corresponds to the opening of the light shaft on the treatment room side.
  • the edge can have one or more reinforcing ribs connected to the light shaft for mechanical reinforcement.
  • the edge can in particular have a basic shape that is rectangular in plan view. In this case, its long sides correspond to longitudinal sections of the edge.
  • the "front surface" of the edge faces the loading opening that can be closed by the door and thus faces a user looking into the treatment room.
  • the fact that the edge flattens out at an incline behind the front surface includes in particular that the front surface or the front or front edge section providing the front surface protrudes the furthest into the treatment room.
  • This has the advantage that treatment room-side areas of the lamp arranged behind (i.e., further in the direction of a rear wall) are at least partially covered.
  • the front surface can cover the opening of the light shaft and the translucent plate from the view of the user, so that a glare effect of the lamp can be noticeably reduced or even completely avoided.
  • the inclined, flattened shape of the edge includes in particular that the edge becomes flatter in the rearward direction or in the direction of the rear wall. This can also be expressed in such a way that the height of the edge decreases in the rearward direction.
  • the light emitted from the light shaft in the direction of the treatment room can be generated by means of one or more light sources of the lamp.
  • the at least one light source can comprise, for example, one or more LEDs.
  • the translucent plate can for example consist of glass, glass ceramic or plastic.
  • the translucent plate can be transparent or opaque ("milky").
  • the translucent plate covers a rear edge section up to the side wall. This has the advantage that a rear area of the treatment room can be illuminated particularly effectively.
  • the translucent plate extends in particular so far over the rear edge section until it hits the side wall (possibly separated by a gap). Starting from an underside of the edge section, it can run bent over to the side wall, which has the advantage that a spatial area located behind the luminaire (i.e. a spatial area between the rear edge section and the rear wall) can also be effectively illuminated.
  • the translucent plate covers lateral edge sections up to a laterally outer protruding bead of the lateral edge sections. In this way, the advantage of a particularly wide light-emitting surface with little glare is achieved when viewed from the side.
  • the first component including the light shaft, the edge and the light-permeable plate is a component produced in one piece. This advantageously enables particularly simple and inexpensive manufacture and a particularly robust component. It is a further development that the first component is an integrally produced 2K plastic component, the transparent plate being made of transparent plastic and the remaining volume of the component being made of opaque plastic. However, the translucent plate can generally also have been manufactured separately and then connected (e.g. latched, glued, etc.) to the remainder of the first component.
  • the lamp has a light source carrier with at least one light source directed obliquely backwards into the light shaft.
  • This enables the advantage of a particularly low glare effect with particularly good illumination of the treatment room under and behind the light.
  • This can also be expressed in such a way that an optical axis or main emission axis of the at least one light source does not run perpendicularly through the opening, but under one Angle of inclination is directed towards the rear wall.
  • the light source carrier can be a circuit board. The angle of inclination can then be implemented simply by means of a correspondingly inclined position of the board.
  • a driver for operating the at least one light source, in particular an LED, can be present on the circuit board.
  • the light source carrier is arranged in the light shaft. In this way, light losses can advantageously be reduced and a light yield (Im / W) of the useful light radiated into the cooking chamber can be increased.
  • the light shaft has a specular or diffusely reflecting surface on the inside.
  • the inside can have a white surface, for example.
  • the white surface can have a coating comprising white pigments, e.g. made of titanium oxide.
  • the edge has a bearing surface for bearing the first component on an inside of the side wall. In this way, the first component can be positioned and attached to the side wall particularly easily.
  • the lamp has a second component arranged outside the treatment room, which can be fastened (e.g. latched) to the light shaft and, in the fastened state, holds the lamp together with the first component in a press fit on the side wall.
  • the front surface is beveled towards the rear starting from the side wall.
  • the front surface is advantageously particularly easy to see for a user looking into the loading opening.
  • the front surface has an inscription.
  • the inscription can have been introduced into the front surface by removing material, for example by scratching, embossing, stamping, lasers, etc. Use a hot stamping foil has been applied.
  • the lettering can also have been printed on, for example.
  • the object is also achieved by a corresponding lamp which is intended (i.e., set up and designed) for installation in a household appliance.
  • the lamp can be designed as described above and provides the same advantages.
  • FIG. 1 shows, in an oblique view, a section through a first component 2 of a lamp 1 for illuminating a treatment room B of a household appliance H, here for example in the form of a cold room of a refrigerator (see FIG Fig. 2).
  • Fig. 2 shows the lamp 1 with the first component 2 and a second component 3 mounted on a side wall, here for example a ceiling D, of the treatment room B.
  • the ceiling D has an opening L.
  • the treatment room B has a front loading opening which can be closed by means of a door (not shown).
  • FIG. 3 shows the first component in FIG. 2, a plan view of a side facing away from the treatment room.
  • Fig. 4 shows the first component 2 in an oblique view of the side facing away from the treatment room.
  • the first component has a light shaft 4 protruding vertically through the opening L and having a tubular basic shape with a rectangular cross section.
  • the light shaft 4 is surrounded laterally by an edge 5 on its subarea protruding into the treatment room B.
  • the edge 5 has a rectangular basic shape, in particular a rectangular ring shape with a front or front edge section 5a, a rear or rear edge section 5b and two lateral edge sections 5c.
  • Light well 4 and edge 5 are made in one piece from an opaque plastic, e.g. by means of an injection molding process.
  • the front edge section 5a provides a front surface 6 that can be seen from the front by a user, the front edge section 5a extending farthest from all edge sections 5a to 5c into the treatment room B. Starting from the ceiling 6, the front surface 6 is beveled or inclined towards the rear and optionally has, as shown, an inscription C introduced, for example, by means of a hot stamping foil.
  • the edge 5 flattens behind the front surface 6 in the rearward direction RR of the treatment room B, in particular analogous to a flat slope.
  • the height of the edge 5 or a distance between its underside and the ceiling D decreases in the rearward direction RR. This has the advantage that the front surface 6 in particular is visible to a user.
  • the light shaft 4 is covered at its opening 7 facing the treatment room B by a light-permeable, in particular transparent, plate 8.
  • the plate 8 has an overlapping region 10, where it covers or overlaps partial surfaces of the lateral edge sections 5c up to the respective laterally outer bulges 11 and the rear edge section 5b up to the ceiling 6.
  • At least the overlapping area 10 is specially designed for the planar light extraction into the treatment room 8, e.g. by means of scattering centers contained therein, a surface structure, a surface roughening, etc.
  • the first component 2 can be manufactured in one piece as a 2K injection-molded component, the translucent plate 8 being made of translucent plastic and the remaining component volume including the light shaft 4 and the edge 5 being made of an opaque plastic.
  • a light source carrier 12 in the form of, for example, a circuit board 14 equipped with one or more LEDs 13 is fastened, for example latched and / or glued, in a section of the light shaft 4 located outside the treatment room B.
  • the circuit board 14 and thus also the LEDs 13 are inclined backwards, as in FIG Fig. 2 indicated by the angle of inclination ⁇ between the ceiling D and a plane E of the board 14. This further reduces the likelihood of a user being dazzled, and a rear spatial area of the treatment room B can be illuminated particularly well.
  • the board 14 and the edge sections 5b, 5c behind the front surface 6 are inclined in the same rearward direction RR, but the board 14 is optionally more inclined.
  • the light source carrier 1 is arranged in the light shaft 4, and the light shaft 4 can be designed to be reflective on the inside, e.g. diffusely reflective by providing white material particles.
  • the first component 2 from the treatment room B with its light shaft 4 is inserted vertically through the opening L until its edge 5 rests on the ceiling D on the inside.
  • the edge sections 5a to 5c provide, at their free edges, a particularly circumferentially closed support surface 15 for resting on the ceiling D on the side of the opening L.
  • the second component 3 is placed on the light shaft 4 of the first component 2 resting on the ceiling D and fastened, e.g. latched onto the corresponding latching lugs 16 of the light shaft 4.
  • the second component 3 can also have resilient "spring areas" 17 in order to increase the contact pressure of the support surface 15 against the ceiling D and thus particularly effectively prevent the lamp 1 from wobbling on the ceiling D.
  • the lamp 1 is held on the ceiling D by an interference fit between the first component 2 and the second component 3.
  • Fig. 5 shows the first component 2 in a view obliquely from behind on a side facing the treatment room.
  • the entire "outer" surface of the translucent plate 8 facing the cooking space serves as a light emitting surface 9, 10 for radiation when the LEDs 13 are switched on of useful light into the treatment room B.
  • the plate 8 is at least approximately divided into the central area 9 and the overlap area 10 covering the lateral edge sections 5c up to the respective bead 11 and the rear edge area 5b up to the support surface 15.
  • the light-emitting surface 9, 10 is significantly larger than the area of the opening 7, indicated by dashed lines, of the light shaft 4 or than just the central area 9 .
  • existing openings L can be used for conventional lamps with a noticeably smaller light-emitting surface that have been built in up to now, which keeps the construction outlay particularly low.
  • the lamp can additionally or alternatively be arranged on a left side wall, right side wall and / or rear wall of the treatment room.
  • the lamp 1 or its components 2 and 3 can also be inventive on their own.
  • the lamp 1 can be described, for example, on the basis of the support plane defined by the support surface 15, which corresponds to the position or orientation of the ceiling D.
  • a numerical specification can also include exactly the specified number as well as a customary tolerance range, as long as this is not explicitly excluded.
