  • a refrigerator and/or freezer is provided with a door with at least one recessed grip, which preferably extends along a horizontal edge of the door, and at least one light source for illuminating the recessed grip, with a light guide being arranged in a recess formed by the recessed grip is, in which light from the lamp to illuminate the recessed grip can be introduced.
  • the light guide is preferably not arranged in a separate recess of its own, but is arranged in the recessed grip itself, preferably on its base and/or on a side wall.
  • the at least one light source is accommodated in a separate, preferably waterproof chamber, which is formed by a housing that has a transparent material at least in sections, preferably in an area between the at least one light source and the light guide, in order to prevent coupling and / or to allow light to pass from the at least one illuminant through the housing into the light guide.
  • the shielding of the illuminant in a separate, in particular watertight chamber increases the service life of the lighting and at the same time reduces its maintenance effort, since the illuminant is protected against splashing water, for example.
  • the section of the housing that has the transparent material is preferably designed as a prism, in particular as a total internal reflection prism (TIR prism).
  • TIR prism total internal reflection prism
  • the light from the illuminant can be introduced into the waveguide in a targeted manner by means of the prism.
  • the housing wall it is also conceivable for the housing wall to consist of or have a transparent material in sections or completely.
  • the light guide preferably has a light guide core, a holding section for fixing the light guide in the recessed grip and/or a cover that preferably serves as a diffuser, with the holding section and the diffuser preferably being designed as a single component.
  • the at least one light source has one or more LEDs, of which at least one LED is preferably a white LED, with the at least one light source particularly preferably has a plurality of white LEDs or an RGB LED and a white LED.
  • a multicolored LED with an integrated white LED could also be used, but the provision of a separate white LED offers the advantage that higher light intensities can be achieved.
  • the at least one illuminant has a red, a green, a blue and a white LED, which are preferably all combined in one component or chip.
  • a red, a green, a blue and a white LED which are preferably all combined in one component or chip.
  • a light source is arranged at each of two opposite ends of the recessed grip and the two light sources are designed to introduce light into a common light guide. In this way, a particularly uniform and bright illumination of the recessed grip can be achieved.
  • the light guide is preferably held in the recessed grip in a detachable or non-detachable manner by means of a positive fit, in particular a snap-in connection, a material connection, in particular an adhesive connection, and/or a frictional connection.
  • two or more illuminants can be connected to an energy source via common wiring or each with separate wiring.
  • the two or more lamps can be controlled in such a way that if one lamp fails, the other lamp or the other lamps compensate for the failure.
  • a further embodiment of the invention relates to a refrigerator and/or freezer with at least two doors, each of which is equipped with at least one recessed grip, a first door being equipped with a lamp on two opposite edges, one of which is designed for this purpose is to illuminate the recessed grip of the first door and the second illuminant is designed to illuminate the recessed grip of the second door.
  • the refrigerator and/or freezer can have two drawers which are arranged one above the other and each have a horizontal recessed grip on their upper edge.
  • the recessed grip of the upper drawer can be directly illuminated by a lamp integrated in the door of the upper drawer and the recessed grip of the lower drawer can be indirectly illuminated by a second lamp integrated in the door of the upper drawer, preferably on its lower edge.
  • the refrigerator and/or freezer can also have at least two doors, each of which is equipped with at least one recessed grip and each has a light source that is designed to illuminate the recessed grip of the associated door.
  • the recessed grip of the upper drawer is preferably illuminated directly by an illuminant integrated in the door of the upper drawer and the recessed handle of the lower drawer is indirectly illuminated by a lamp integrated in the door of the lower drawer.
  • the at least one door of a refrigerator and/or freezer according to the invention is preferably a front side of a pull-out drawer.
  • this is only to be understood as an example and other doors, such as doors that can generally be pivoted about hinges, doors of a side-by-side or French door device, etc., are also covered by the present invention, which can basically be applied to any recessed grip .
  • two drawers arranged one above the other are provided in a refrigerator and/or freezer, each of which has a door 1 or 2 .
  • the door 1 of the upper drawer has a first recessed grip 3 and the door 2 of the lower drawer has a second recessed grip 4.
  • the viewing direction of a user standing in front of the refrigerator and/or freezer is in 1 marked by an arrow.
  • the upper drawer or its door 1 has two lamps 5, 6, which each directly illuminate the recessed grip 3 of the upper door 1 and indirectly the recessed grip 4 of the lower door 2.
  • the lower drawer or its door 2 does not have its own light source. Instead, the recessed grip 4 is illuminated by the lighting means 6 of the first door 1, which is arranged on an end surface of the door 1 facing the lower drawer.
  • the light source 5, in particular the light guide, is arranged on or in a side wall of the recessed grip 3.
  • the recessed grips 3 and 4 are preferably at least partially lined with a light-reflecting material in order to improve the illumination of the recessed grip.
  • the recessed grip 4 of the second door 2 is also directly, by means of an existing in the recessed grip 4 light source 7 illuminated.
  • the lamps 5 and 7, in particular their light guides, are each arranged on or in a side wall of the respective recessed grip 3 or 4.
  • the light sources are preferably arranged, for example, on the right and/or left end of a recessed grip and the light guide extends along the recessed grip on or in its side wall and/or on or in its base or floor area.
  • FIG 3 shows another embodiment of the invention, according to which the recessed grips 3 and 4 are each directly illuminated by a light source 5, 7 arranged in the associated door 1,2.
  • the lamps 5 and 7, in particular their light guides are each arranged on the base or on the bottom of the respective recessed grip 3 or 4.
  • the light sources 5 and 7, in particular their light guides, are arranged within the recessed grips 3 or 4, which are formed by the contours 8 and 9, respectively.
  • FIG 4 shows a separate chamber in which the illuminant is housed.
  • FIG 5 The illustration shown shows, for example, an LED circuit board 10 which is housed in a separate and watertight chamber with a housing 11 . Energy is supplied to the LED board 10 by means of a cable 12.
  • an area 13 of the housing 11 of the chamber is made of a transparent material, so that light from the LEDs 16 can be introduced through the transparent area 13 and via a prism 14 into the light guide 15 .
  • Figure 1 shows how the light from the LEDs 16 is introduced through the transparent area 13 of the housing into the prism 14 and then into the waveguide 15.
  • another prism 17 can also be provided, by means of which the light from the LEDs 16 is deflected and introduced into the light guide 15 .
  • the light guide 15 has, as in 7 shown, in this embodiment an optical fiber core 18 which is arranged between a holding portion 19 and a cover in the form of a diffuser 20.
  • the diffuser 20 has a surface structure 21 on its upper side, which enables a particularly uniform emission of light.
