Definitions

  • the invention relates to a laundry treatment device with illuminated process space.
  • the light source is arranged outside the process container, and the process container has a light transmittance of at least 10%, in particular at least 30%, in the area illuminated by the light source.
  • the "area illuminated by the light source” is to be understood as that area of the process container in which the light intensity lies between a maximum light intensity and at least 50% of this maximum light intensity during operation of the light source. In other words, it is the (within this range) the brightest illuminated area of the process container.
  • a breakthrough in the illuminated area can be dispensed with in the process container.
  • the wall of the process container in the illuminated area is thus continuous.
  • a breakthrough in which, for example, a window or a light guide would be used would be associated with additional costs.
  • a breakthrough would require an additional seal which prevents the medium (eg, water, humid air) from leaking out of the process container. This additional seal is a potential source of defect.
  • the process container in the illuminated area is optically transparent. It is sufficient if it is optically diffuse (this term is defined below). Thus, for the process container conventional, inexpensive materials come into question, such as diffuse plastic.
  • the illuminated area is advantageously located on the tub, and in particular on a lateral surface of the tub, i. on an outer surface of the tub which extends essentially parallel to the axis of rotation.
  • At least three light sources are advantageously arranged in different azimuthal positions on the tub, in particular distributed over an angular range of at least 30 °, in particular at least 60 °. Thereby, a complete or strong shading of the light due to the passing ribs of the drum can be avoided.
  • the illuminated area is advantageously formed by that part of the wall of the process container which extends between the drum and the user door. This allows the drum to be made of any material, especially metal, as in conventional equipment. Only the mentioned wall must be sufficiently translucent.
  • the laundry treatment device further has a controller which controls the components of the device and in particular the light source.
  • the controller can be configured such that it switches on the light source during the treatment of the laundry, ie the light source is not or not only activated before or after the laundry treatment. In this way, the user can be given insight into the process, and / or information about the light source can be communicated to the user, for example concerning the operating status of the laundry treatment device.
  • controller can also be designed to periodically switch the light source on and off, whereby additional information can be transmitted or optical effects can be generated.
  • the frequency of the periodic switching on and off of the light source can differ from the rotational frequency of the drum by at most 10%, in particular by at most 1%.
  • a quasi-standing or slow-moving image of the laundry in process space is created for the user, which is e.g. allows a closer monitoring of the process.
  • a body is said to be optically diffuse if it diffuses at least 50%, in particular at least 80%, of the light originating from the light source and transmitted through the body.
  • the term diffuse is understood to mean that the predominant part of the scattering is to structures having a size of less than 100 ⁇ m, preferably to local inhomogeneities in the optical properties of the body.
  • the process container is convex in one area when it is curved outward (seen from the interior).
  • the washing machine has a stationary housing 10 in which a tub 11 is arranged.
  • the tub 11 is held with a suitable suspension 12 elastically deflectable in the housing 10.
  • a drum 14 is arranged, which is rotatably mounted about a, for example horizontal, axis of rotation 15.
  • the drum 14 can be rotated about the axis of rotation 15 with a drive motor 16 via a belt 17.
  • the tub 11 is closed by a user door 16.
  • Vat 11 has a cylindrical lateral surface 18 concentric with the axis of rotation 15 and a rear wall 19, which is advantageously approximately perpendicular to the axis of rotation 15.
  • Vat 11 is advantageously made predominantly of plastic, for example in the form of two half-shells, which are interconnected in the middle.
  • Drum 14 advantageously has a likewise cylindrical jacket 20 and a rear wall 21 which is advantageously perpendicular to the axis of rotation 15.
  • These parts can be made of metal, for example.
  • the cylindrical shell 20 of the drum 14 has a plurality of perforations through which water can flow radially into and out of the drum 14.
  • drivers 24 can be arranged in a manner known per se in order to move the laundry located in the drum 14.
  • the device according to Fig. 1 and 2 also has a controller 30, with which the functions of the device can be controlled in a conventional manner.
  • three light sources 32 which serve to throw light into the interior of the drum 14.
  • Each of these light sources 32 is arranged on the lateral surface 18 of the tub 11. The exact structure is over Fig. 3 seen.
  • the light source 32 has a holder 34, which is suitably connected to the tub 11, for example by gluing, screwing or otherwise.
  • a holder 36 mounted on the carrier 36 is provided, which may be configured for example as a metal plate and also serves as a heat sink.
  • a row of LEDs is attached as lights 38, which are aligned so that their light falls on the outer wall of the tub 11. There it defines an illuminated area 40 on the wall 18.
  • the tub 11 is translucent at least in the illuminated area 40, and preferably also beyond this area.
  • the light transmittance of the wall of the tub 11 in the illuminated area 40 for the visible light from the light source 32 is advantageously at least 10%, in particular at least 30%.
  • the wall of the tub 11 is transparent. It can also be optically diffuse.
  • the tub 11 or the process container in the illuminated area 40 consists predominantly of plastic, such as polypropylene.
  • the process container is made of a glass fiber reinforced plastic, such as e.g. made of polypropylene with a 40% glass fiber reinforcement.
  • Such a material has a relatively low optical absorption, so that a large part of the light from the light source 32 can get into the interior of the tub.
  • the whole tub 11 is made of plastic.
  • the thickness of the tub 11 or the process container in the illuminated area 40 is advantageously between 0.5 and 5 millimeters.
  • the light passing through the jacket 18 of the tub 11 strikes the outside of the drum 14 and can there through the perforations in the drum shell 20, ie through the openings 44 of Fig. 3 , enter the interior of the drum 14 to illuminate the laundry.
  • a plurality of light sources 32 are distributed over the circumference of the tub 11, in different, with respect to the axis of rotation 15 azimuthal positions, as in Fig. 2 is shown. Preferably, they are distributed over an azimuthal angular range ⁇ of at least 30 °, in particular of at least 60 °. In this way it can be ensured that only a minority of the light sources 32 can be shaded by one of the drivers 24.
  • Fig. 4 shows a clothes dryer, which has a stationary housing 50.
  • a drum 54 is rotatably disposed about a rotation axis 52.
  • the drum 54 is closed by a user door 56, via which the user can access the interior of the drum 54 in order to load it with laundry or to remove it from laundry.
  • the drum 54, the wall portion 58 and the user door 56 together form a process space which encloses the laundry to be dried.
  • the light source 32 is arranged on the wall section 58.
  • the exact structure of the light source with the adjacent wall portion 58 results from Fig. 5 and essentially corresponds to that according to Fig. 3 in that the light source 32 has a holder 34 which is suitably connected to the wall portion 58, for example by gluing, screwing or otherwise.
  • a support 36 mounted on the holder 36 is provided, which may be configured for example as a metal plate and serve as a heat sink.
  • a row of LEDs are attached as lights 38, which are aligned so that their light falls on the wall portion 58. There it defines an illuminated area 40 on the wall portion 58.
  • the wall section 58 is translucent at least in the illuminated region 40, and preferably also beyond this region.
  • the light transmittance of the wall portion 58 in the visible light illuminated area 40 from the light source 32 is advantageously at least 10%, more preferably at least 30%.
  • the wall portion 58 is transparent. It can also be optically diffuse.
  • the lighting for the washing machine or the tumble dryer according to the embodiments described above can be used to illuminate the process space during loading and / or unloading.
  • controller 30 may also be configured to turn on the light source (s) 32 during the treatment of the laundry, particularly when the user door 16 or 56 is transparent.
  • the light source (s) 32 may also be configured to produce different types of light with different colors. Again, this can be used to convey information to the user. For example, a red light may indicate a fault condition, or a high temperature in the process room. In contrast, a green or blue lighting can signal a proper state or a low temperature.
  • the switching on and off can be done continuously, i. Continuously brighter or darker over at least one or more particular seconds, or the lighting can suddenly be switched on or off.
  • the light source 32 has a holder 34 separate from the carrier 36.
  • the holder 34 and the carrier 36 are formed by the same component, ie that the carrier 36 is connected to the outside of the process container.
  • Such an embodiment is in Fig. 6 represented where the holder and the carrier as a common component, the reference numeral 34.
  • Fig. 6 shows a further measure, which regardless of the configuration of the holder 34 and the carrier 36 with the solutions according to Fig. 3 or 5 can be combined, namely that the wall 18, 58 of the process container in the illuminated area 40 is diluted (compared to the adjacent to the illuminated area 40 area 40 '), preferably by at least 50%. In this way, the light transmission can be improved without compromising the structural integrity of the container.
  • a recess 60 is provided on the outside (i.e., on the side opposite the process space) of the process container in the illuminated area 40.
  • the light (s) 38 of the light source 32 engage or engage in this depression 60.
  • the process container is in the illuminated area 40 on its inner side (ie towards the process chamber) flat or convex (ie arched outwards), which can be avoided in the process space projecting parts.
  • the process container is also in an area 40 'adjacent to the illuminated area (see FIG Fig. 3 ) a width of at least 2 cm also flat or convex, ie it is not necessary to provide a recess or the like in the process container in the field of illumination.
  • the process container in the illuminated area 40 for the light of the light source 32 has a light transmittance of at least 30% and / or of at most 70%.
  • a washing machine or a tumble dryer which (r) has a process space that can be illuminated.
  • at least one light source 32 is provided for illuminating the process space. This throws light from outside onto a wall of the process room, and in the illuminated area, this wall is designed so that it lets through at least part of this light.
