Definitions

  • the present invention relates to a refrigerator comprising a convertible compartment in which a flow of cold air is fed and a damper system for adjusting such flow in order to regulate temperature in said convertible compartment.
  • the above refrigerators and related convertible compartments are well known in the art of domestic refrigeration appliances. Such compartment can be customized by the user in order to adapt a certain compartment of the refrigerator, in addition to traditional fresh food and freezer compartment, to a certain kind of food to be stored. Usually the cold air is flown by the freezer compartment by means of a conduit and related fan.
  • the convertible compartment presents a cold air flow distributor with a single motor and gear mechanism to control air flow in the two regions.
  • the gear mechanism rotates two rotary valves at different rates which cooperate with two openings thereby allowing controlling actual area for air passage on each side of the compartment independently.
  • a refrigerator 10 comprises a fresh food compartment RC, a freezer compartment FC and a convertible compartment 12 placed between the fresh food compartment RC and the freezer compartment FC.
  • the convertible compartment 12 has an inner liner 12a provided with a back aperture 14 for allowing the inflow of cold air from the freezer compartment FC though a conduit 16.
  • a flow distributor 18 which divides the compartment in an air plenum 20 and in a storing chamber 22 which is divided in two sub-chambers 22a and 22b by means of a vertical separator 24.
  • a bin 26 which can be extracted from the chamber 22 when a door 28 is pulled by the user.
  • the flow distributor 18 comprises a wall 30 which is fixed in an air tight manner within the inner liner 12a and a shaped cover 32.
  • the wall 30 and the cover 32 have each two openings 34 and 36 respectively shaped as parts of circle rings.
  • Between the wall 30 and the cover 32 is defined a thin space where two rotating discs 38 and 40 are placed, each disc having an opening 42 corresponding to the shape of the openings 34 and 36 of the wall 30 and of the cover 32 respectively.
  • Each disc has a geared edge G in order to cooperate with a gear mechanism comprising a motor gear 44, a compound gear 46 and an idle gear 48.
  • the motor gear 44 is driven by an electric motor 50 supported by the wall 30 and by the cover 32.
  • Figures 5 to 10 show certain configurations of the flow distributor according to the invention, as seen from direction Z ( figure 3 ).
  • the "right” disc 40 rotates at a higher speed than the "left” disc 38 (where right and left are opposite to the above definition).
  • Figure 5 shows an open-open configuration corresponding to 0° or 4turns + 120°.
  • Figure 6 shows an open-partially open configuration corresponding to 78°.
  • Figure 7 shows an open-close configuration corresponding to 156°.
  • Figure 8 shows a close-open configuration corresponding to 1 turn + 264°.
  • Figure 9 shows a partially open - close configuration corresponding to 1 turn + 108°.
  • Figure 10 shows a partially open-open configuration corresponding to 312°.
  • the actual temperature in the sub-compartments 22a and 22b depends on the actual temperature in the freezer compartment FC, on the dimension of the conduit 16, on the actual flow rate driven by the fan F (depending also on the dimension of the return conduit , not shown), and on the insulation of the convertible compartment 22 as well.
  • a designer can therefore establish the actual link between the percentage of the openings and the actual temperature in the sub-compartments by carrying out experimental test. Once such relationship is established, the designer will program the control unit of the refrigerator, and particularly the control unit associated with the flow distributor 18 (indicated with reference K in figure 2 ), accordingly.
