Definitions

  • the present invention relates to a refrigeration appliance, in particular a household refrigeration appliance with a housing which comprises a body and a door which surrounds an interior space for storing refrigerated goods, and a luminaire for illuminating the refrigerated goods and a luminous surface mounted outside the housing.
  • Such a refrigerator has a door operated switch to turn the light on with the door open and off with the door closed.
  • Refrigeration appliances which have a luminous surface which is mounted on the outside of the housing and whose luminous status provides information about the instantaneous operating state of a refrigerating machine of the appliance.
  • Object of the present invention is to provide a refrigeration device in which the light is supplied for illuminating the refrigerated goods a second useful use.
  • the object is achieved by the light is arranged in a refrigeration device of the type specified above, to illuminate the refrigerated goods with the door open and the illuminated area when the door is closed.
  • the light can also be used to indicate the operating status.
  • the refrigeration device can provide an optical warning signal which is easily perceivable even in a bright environment in order to draw attention to a possible malfunction.
  • the beam of the lamp may be directed into the interior with the door open in order to illuminate the refrigerated goods therein. If the goods to be cooled are conveniently movable, for example by being housed in a box which can be pulled out of the interior, the beam of the lamp can also be aligned with an area in front of the interior in order to illuminate the contents of the box pulled out. While the lamp to be able to effectively illuminate the item to be refrigerated, will usually be attached to the body, the luminous surface is to be well visible, preferably on the door.
  • an optical waveguide is preferably arranged between the two.
  • the light guide is arranged on the door and movable with this.
  • the light guide with the door open must release a beam path from the lamp to the refrigerated goods, so that it can be illuminated, he can expediently engage in the closed position of the door in this beam path to intercept the light and supply the light area.
  • the luminaire is movable between a position for illuminating the item to be cooled and a position for illuminating the luminous area. This is particularly useful when the refrigerated goods to be illuminated in the interior.
  • the lamp is fixed in the position for illuminating the luminous surface by contact with a contour of the door. As soon as the door is opened, contact with the contour is lost and the luminaire can switch to the position for illuminating the item to be cooled.
  • the body may have a projecting over a sealing plane projection on which the lamp is mounted.
  • waste heat of the lamp can freely escape into the environment without heating the interior.
  • the luminous area Since the extent of the luminous area is very small compared to the interior, a light signal on the luminous area is still well visible even when the luminosity of the lamp is lower with the door closed than with the door open. Corresponding to the luminous intensity, the waste heat output of the luminaire is also reduced, with the result that any additional heat input into the interior resulting from the operation of the luminaire is negligible.
  • the luminance can be reduced without reducing the efficiency by reducing the number of LEDs operated or the duty cycle of a pulse current applied to the LEDs.
  • the luminosity of the luminaire may vary at least when the door is closed according to a predetermined pattern, which is determined as a function of the respective operating state of the refrigerator ,
  • the lamp may in particular comprise a plurality of LEDs in different colors.
  • an outer surface of the door is formed by a transparent disk, and the luminous surface is provided on an inner surface of the disk.
  • Fig. 1 shows a perspective view of a combination refrigerator with a body 1 and doors 2, 3, the separate storage compartments such as a normal refrigeration compartment and a fresh refrigerator compartment close.
  • Both doors 2, 3 have in their upper region in each case a luminous surface 4, 5, which may be formed as an abstract geometric shape, for example, a narrow, upright rectangle in the case of the luminous surface 4, or a lettering in the case of the luminous surface 5 ,
  • the outer surfaces of the doors 2, 3 are each formed in one piece from a glass pane, preferably made of hardened mineral glass, behind which the luminous surface 4 or 5 can only be distinguished from the remaining surface of the door when it is illuminated from behind.
  • Fig. 2 shows an enlarged cross section through the facing edges of the doors 2, 3 and a horizontal partition 6, which extends between the two compartments, here denoted by 7 and 8, the body 1 extends.
  • the doors 2, 3 are provided in a conventional manner on its inner side facing the body 1 each with a peripheral magnetic seal 9, which in the closed position of the door 2 and 3 at a Front of the body 1 rests and the compartments 7, 8 is substantially airtight from the environment.
  • a lamp 11 Adjacent to a front edge 10 of the partition 7, against which the magnetic seals 9 abut, on the underside of the partition wall 6, a lamp 11 is arranged, which comprises a plurality of powerful white light LEDs.
  • the lamp 11 radiates obliquely downward and forward, and their light falls on a light guide 12, which extends transversely through the door 3 to the inside of the aforementioned glass plate, here denoted by 13.
  • the light guide 12 may be a homogeneous block of a clear material such as PMMA, in which the light of the lamp 11 is rectilinear or possibly by total reflection at the interfaces led to the light emitting surface 5 on the inside of the glass plate 13 propagates.
  • Fig. 3 shows the refrigerator with the door open 3 and an extracted drawer 14.
  • an inlet window 15 of the light guide 12 can be seen.
  • the light of the lamp 11 no longer reaches the inlet window 15, but illuminates the contents of the extracted drawer 14.
  • Fig. 4 illustrates this fact by means of one Fig. 2 analog section.
  • the light 11 is constantly in operation, either to illuminate the light area 4, or to illuminate an extracted drawer 14. Since the extent of the luminous area 4 is substantially smaller than the surface of the pull-out box 14 to be illuminated, in normal operation with the door 3 closed a considerably lower power is sufficient than with the door 3 open in order to make the luminous area 5 clearly visible. Such a lower power can be generated with good efficiency by a plurality of LEDs of the lamp 11 is a first group regardless of the position of the door 3 is powered, while the LEDs of a second group are powered only when the door 3 is open.
  • a user can read off the light area 4 bright or dark in the state whether the refrigeration appliance is properly supplied with power or not.
  • the luminous area can be used to provide further information.
  • Many refrigerators have an intensive cooling mode that can be activated by a user for a limited time to quickly cool down large quantities of newly stored refrigerated goods. The fact that such an intensive cooling mode is active can be clearly indicated by operating the lamp 11 with the door closed at a higher power than in the normal cooling mode.
  • An energy-saving mode of operation that can be selected by a user, for example, for periods of absence, in which there is no perishable refrigerated goods in the device, and for example, allows a slightly higher storage temperature than in normal cooling mode, or by allows greater temperature fluctuations, allows longer compressor run times can be displayed by a slow change of the lamp 11 between the brightness level of the normal operating state and dark.
  • a quick change between dark and high light power for example the power level used with the door open, can be used.
  • the light 11 for indicating a fault also LEDs of a different color, preferably red, have, which are energized only in case of failure.
  • a luminaire that supplies light for the luminous surface 4 may, similar to the luminaire 11 on the intermediate wall, be mounted on a ceiling of the body 1 and how the luminaire 11 may be energized in different ways depending on the operating state of a refrigerating machine.
  • Fig. 5 shows a schematic section through an upper edge of a door 2 or 3 and the partition wall 6 or a ceiling of a storage compartment according to a first Development of the invention.
  • the door 3 has, in a manner known per se, a flat projection 16, which engages in the compartment 7 via a plane defined by the circumferential magnetic seal 9.
  • the projection 16, together with the partition wall 6, defines a narrow gap 17 which severely restricts the exchange of air between the compartment 7 and a cold inside of the magnetic seal 9.
  • the lamp 11 is arranged so close to the front edge 10 of the partition 6, that it is opposite to an upper edge 18 of the projection 16 with the door closed. So the lamp 11 is thermally insulated against the subject.
  • FIG. 6 Another training shows Fig. 6 ,
  • the partition wall 6 is extended above the door 3 by a projection 20 forward, and the lamp 11 is arranged in front of a plane defined by the magnetic seal 9, outside the refrigerated compartment 8, and radiates to a formed in an upper flank of the door 3 Inlet window 15 of the light guide 12. Waste heat of the lamp 11 passes unhindered into the open, without burdening the tray 8.
  • Fig. 7 shows a cross section through mutually facing edges of the doors 2, 3 and a front portion of the partition wall 6 according to a fourth embodiment of the invention.
  • the lamp 11 is here received in a recess directly on the front edge 10 of the partition 6 pivotally about a horizontal axis.
  • a projection 19 of the door 3 engages in a complementary receiving notch of the lamp 11 and holds it against gravity or against a return spring, not shown here in a position in which they obliquely downward and forward, on an inlet window 15 of a through the Door 3 extending light guide 12 radiates.
  • a lamp 11 When the door 3 is opened, the projection 19 protrudes from the notch, and the lamp 11 pivots into an in Fig. 8 shown orientation in which it radiates obliquely downwards and backwards into the compartment 8.
  • Such a lamp 11 is particularly suitable for a compartment in which refrigerated goods are not stored in pull-out boxes, as described above, but also stationary, plate-shaped refrigerated goods stands.
