Definitions

  • the present invention relates to a chest freezer having a lid hinged to a cabinet and a lighting device comprising at least one light source located on a lower surface of the lid.
  • Chest freezers known also as horizontal freezers, have a lighting system currently consisting of a lamp holder with integrated gravity switch. During door opening a ball or reed sensor inside the lamp holder closes an electric circuit and activates the lamp.
  • lamp position, switch-on angle of the lid and light intensity are fixed. At different open angles light could be perceived as too low by the user (chest freezers are commonly placed in rooms where artificial lighting is reduced) or directed in a way to disturb the user. Moreover, the switch on at maximum intensity of the light when the lid is open could temporarily make blind the user, particularly when the freezer is placed in room with a low general illumination (cellars or the like).
  • the technical solution according to the invention comprises a lighting module, preferably a led lighting module, with a dedicated sensor by which light intensity increases by door opening angle.
  • the circuit board associated to said sensor and to the lighting module can also integrate the user interface and all product functions like temperature setting, lamps indicating functions and visual or acoustic alarms.
  • the solution according to the invention releases light at higher level depending on door position with continuous increasing and does not present risk for user eyes.
  • the solution according to the invention increases safety because led light source is fed at low voltage reducing also risks in case of defects or contact with food overstock.
  • a chest freezer 10 comprises a cabinet 10a and a lid 10b hinged at 12 to the cabinet 10a.
  • a lighting assembly 16 is placed which further integrates the user interface of the chest freezer 10.
  • the lighting assembly 16 is box-shaped and presents a front face 16a, parallel with the lid 10b and having one or more setting knobs 18 and lights 20 indicating the functioning of the appliance.
  • a angle sensor (not shown) is integrated with the hinge 12 and is connected to a central control unit of the freezer 10 (mounted inside the lighting assembly 16) for adjusting the intensity of the light emitted by the led 22 from zero (closed lid, position shown in figure 1 ) to a maximum level corresponding to a substantially vertical position of the lid 10b.
  • the sensor associated with the hinge 12 switches on the led 22 and provides in a continuous or step-wise mode an increase of the light intensity emitted by the led 22.
  • the light intensity emitted by the lighting assembly 16 increases from a horizontal to a vertical position of the lid 10b, it is also possible to adjust the lighting intensity in different pattern, depending on the dimension of the freezer, on the position thereof and on preference of the user. It is also possible to provide on the lighting assembly a further knob for choosing the maximum intensity of the led 22.
