Definitions

  • the present invention relates to refrigerator shelves and in particular to an adjustable refrigerator shelf providing in-shelf lighting.
  • Lights in a refrigerator are typically mounted to the interior walls of the refrigerator compartment. While these lights provide sufficient illumination when the refrigerator is empty, when the shelves are filled with goods, light is blocked and portions of the shelves are cast in shadows.
  • Refrigerator shelves are typically adjustable in position and can be removed entirely from the refrigerator for cleaning. While releasable electrical connectors could be provided for connecting electricity to the shelves, these connectors necessarily but undesirably break the continuous inner wall of the refrigerator and expose conductors making cleaning the inner surface of the refrigerator more difficult.
  • the invention described in this application uses inductively coupled power transfer between a primary coil positioned behind the walls of the refrigerator and corresponding coils on the shelves.
  • An elongated primary coil spanning multiple shelf locations may be used to provide flexibility in the arrangement of the shelves.
  • the present invention combines a wireless transmission system with a shelf bracket allowing rapid adjustment of the shelf up and down without removal of the shelf.
  • the assembly provides an improved structure for holding the broad area wireless coils that simultaneously provides the benefits of rapid shelf adjustment.
  • the design permits the sharing of one of the transmitter or receiver coils among shelf positions reducing total cost.
  • the invention integrates wireless power-transmitting coils into a special refrigerator wall plate that permits wireless lighting to be added to a given refrigerator model simply by attaching the wall plates to the inside of the refrigerator walls at a late stage in manufacturing.
  • the present invention provides a wireless illuminated refrigerator shelf assembly usable with a refrigerator and including a power-transmitting coil adapted to attach to a refrigerator wall to transmit a low frequency electromagnetic field.
  • a shelf receivable within the refrigerator extends between refrigerator walls, and a cardioid track and pin assembly provides an interface between the shelf surface and at least one of the refrigerator walls to stably rest at two different heights on the refrigerator walls in response to successive upward or downward motions of the shelf surface.
  • At least one power reception coil is attached to move with the shelf surface to receive a low frequency electromagnetic field from the power-transmitting coil and provide an electrical current and a set of the light emitting diodes receiving the electrical current and supported by the shelf to provide a source of illumination moving with the shelf.
  • the power-transmitting coil may extend between the two different heights to overlap with the power reception coil at the two different heights.
  • the wireless illuminated refrigerator shelf assembly may include first and second power reception coil positions to alternately align with the power-transmitting coil at the two different heights.
  • the wireless illuminated refrigerator shelf assembly may further include a circuit switching between the two different power reception coils depending upon which power reception coil is receiving power.
  • the circuit may comprise a diode array.
  • the wireless illuminated refrigerator shelf assembly may include a first and second power-transmitting coil positioned to alternately align with the power reception coil at the two different heights.
  • the wireless illuminated refrigerator shelf assembly may further include a shelf sensor controlling power to the first and second power-transmitting coil according to whether a power reception coil is positioned nearby.
  • the cardioid track may be affixed to a refrigerator wall and the pin assembly is attached to move with the shelf.
  • the power- transmitting coil may surround a groove of the cardioid track receiving the pin. [0026] It is thus a feature of at least one embodiment of the invention to closely integrate the power-transmitting coil and the cardioid track to maximize refrigerator usable volume.
  • the cardioid track may alternatively be attached to move with the shelf surface and the pin is affixed to the inner wall of the refrigerator.

  • Fig. 12 is a fragmentary view similar to that of Fig. 11 showing a combination of power from two power receiving coils.
  • a refrigerator 10 may provide for a housing 12 having left, right, top, bottom, and rear insulated walls together defining generally an enclosed rectangular volume open at the front.
  • a door 14 may hinge at a front edge of one side wall to provide, when closed, a refrigerated volume maintained at a desired temperature by a compressor system (not shown).
  • One or more horizontal, planar shelves 16 may be placed within the volume at various heights as supported by quick adjustment shelf brackets 18 on the left and right sides (only the right wall plate is shown).
  • the shelf 16 may include an outer frame 23, for example, constructed of an opaque thermoplastic material to hide wiring and circuitry and supporting a center transparent portion 19, for example a pane of tempered glass.
  • the outer frame 23 on its left and right edges may support a vertically extending shelf plate 25 providing a cardioid track 26 exposed outward on the left and right surfaces to abut inner walls of the refrigerator 10 (shown in Fig. 1).
  • the outer frame 23 may hold one or more light emitting diodes 36 positioned in the frame 23 to be directed upward to illuminate goods placed on the transparent portion 19 or downward to illuminate goods placed on a lower shelf (not shown).
  • the quick adjustment shelf bracket 18 provides a connection between the shelf 16 and inner walls 22 of the refrigerator 10 allowing the shelf to be raised and lowered between two different heights simply by pressure on the shelf without direct access to the quick adjustment shelf bracket 18.
  • the walls 22 of the refrigerator 10 may provide an outwardly extending pin 28 retained in a slide track 30 to move horizontally left and right.
  • the pin 28 may engage the cardioid track 26 in a rear surface of the shelf plate 25 which, as will be described below, cooperates to stably hold the shelf plate 25 and hence the shelf 16 in an upper or lower position.
  • the shelf plate 25 may be retained slidably in vertical alignment by a vertical guide mechanism, for example, outwardly extending left and right vertical tracks 34 on the shelf plate 25 engaging corresponding channels 39 positioned to the left and right of the shelf plates 25 when mounted against the walls 22. This or a variety of other mechanisms may be used to constrain the shelf plate 25 for vertical travel.
  • a power-transmitting coil 37 may be positioned behind the refrigerator wall 22 adjacent to the location of the shelf plate 25 to be attached to a source behind the wall 22.
  • the cardioid track 26 may be a groove extending into the shelf plate 25 from its rear face and is generally an inverted heart-shape having two lower lobes joining to an upper vertex.
  • the cardioid track 26 guides the pin 28 as it moves between two stable positions: a lower position (with respect to the shelf plate 25) with the pin 28 at position 46a being in a notch between the lobes of the cardioid, and an upper position with the pin at position 46b at the uppermost vertex of the cardioid track 26.
  • the upper position of the pin 28 represents the lowest position of the shelf 16 and vice versa.
  • the cardioid track 26 is generally asymmetric so that the pin 28, starting at position 46b and moving downward with respect to the shelf plate 25 with a lifting of the shelf 16 and shelf plate 25, will follow a leftmost groove of the cardioid track 26 to a position 46c in the leftmost lobe of the cardioid track 26 where the pin 28 is trapped against further relative downward motion.
  • New, upward motion on the shelf 16 and shelf plate 25 causes the pin 28 to move downward relative to the shelf plate 25 to position 46d in the rightmost lobe of the cardioid track 26 where subsequent upward motion of the pin 28 from this position (by downward motion of the shelf plate 25) causes it to return to position 46b.
  • the shelf plate 25 may support first and second power receiving coils 38a and 38b positioned to be alternatively in alignment with the power- transmitting coil 37 when the shelf plate 25 is in the uppermost or lowermost positions.

  • the pin 28 extends into a cardioid track 26, as will be described, open on the outer surface of the wall plate 31 to follow the cardioid track 26 as traveler 21 moves up and down along the wall plate 31.
  • shoulder portion of the wall plate 31 is shown, it being understood that this shoulder portion may be attached to a stand-off portion so that the shoulder portion is spaced from a wall of the refrigerator to permit free travel of the traveler 21 up and down the shoulder portion.
  • the traveler 21 may be attached to a shelf frame 23 which, in turn, holds the transparent portion 19 and LEDs 36 as before.
  • the cardioid track 26 may be a groove extending inwardly into the wall plate 31 from an exposed face of the wall plate 31 and, as before, generally heart-shaped albeit inverted with respect to the previous embodiment having two upper lobes joining to a lower vertex.
  • the cardioid track 26 guides the pin 28 between two stable positions: position 46b being at the lowermost vertex of the cardioid, and position 46a being in a notch below the lobes of the cardioid.
  • the cardioid is generally asymmetric so that the pin 28, starting at position 46b and moving upward with a lifting of the shelf 16 and frame 23, will follow a right most groove of the cardioid track 26 to a position 46c in the rightmost lobe of the cardioid where the pin 28 is trapped against further upward motion.
  • the wall plate 31 may be molded thermoplastic to provide a concave rear surface receiving a power-transmitting coil 37 within the wall plate 31 between the wall plate 31 and a wall 22 of the refrigerator and surrounding the cardioid track 26 and may include a cutout portion 33 allowing it to be closely positioned to the power receiving coil 38.
  • the wall plate 31 may be mounted to the wall 22 of the refrigerator by means of one or more self-tapping screws 35 or other assembly techniques so that it may be added to refrigerator 10 with only the addition of a small hole 41 in the wall 22 for power to the circuitry of the power-transmitting coil 37.
  • the power-transmitting coil 37 may extend the full height of the wall plate 31 to provide an oscillating magnetic field that may be inductively coupled to the power-receiving coil 38 at the two positions of the shelf.
