Definitions

• the present invention refers to a cooling and/or freezing apparatus, particularly to a cooling apparatus having at least two compartments that can be closed with one door only, and a cooling system comprising at least one compressor, at least one condenser, at least one evaporator, at least one blower for circulating air in said compartments, and at least one means for regulation of refrigerant flow.
• a cooling apparatus of the aforementioned kind is know from the publication of the patent application No. EP 2 224 194 A2.
• Said documents discloses a cooling and/or freezing apparatus having at least two compartments inside said apparatus comprising several blowers for circulating air, wherein each time at least one blower being associated with one compartment.
• said known solution have a disadvantage of the inefficient temperature regulation in respective compartment.
• a vertical partition wall extending through compartments of said apparatus is arranged at a distance from a rear side of a cooling and/or freezing apparatus.
• Evaporators are arranged vertically with regard to said apparatus, one above the other, in a spacing between said rear side and said vertical partition wall.
• each compartment is provided with at least one shelf and/or at least one pull-out drawer to receive and store goods, wherein at least one of said shelves being displaceable in a horizontal plane and serves simultaneously as a cover for said drawer.
• a cut-out encased by a blower body is formed in said vertical partition wall, said cut-out penetrates said partition wall and fluidly connects the compartment with said spacing.
• a channel is formed in said vertical partition wall which fluidly connects via said blower body said compartment with said spacing.
• Fig. 1 shows a cross-sectional view, in a vertical plane, of a cooling and/or freezing apparatus according to the invention
• Fig. 2 shows schematically a cooling and/or freezing apparatus according to the invention.
• a cooling and/or freezing apparatus comprises at least two compartments, in particular embodiment a first, upper compartment 2 with a first temperature field and a second, lower compartment 3 with a second temperature field, both compartments can de closed by means of one door only.
• Said compartments 2, 3 are mutually separated by means of a horizontal partition wall 4.
• evaporators 8, 9 are arranged vertically with regard to said apparatus, one above the other, being either incorporated in said rear side 5 or slightly spaced from it.
• each compartment 2, 3 is provided with at least one shelf and/or at least one pull-out drawer to receive and store goods.
• said upper compartment 2 is provided with a plurality of shelves 10 placed one above the other, and the lower compartment 3 is provided with a plurality of pull-out drawers 11 placed one above the other and at least one horizontally displaceable shelf 12 serving simultaneously as a cover for said drawer 11.
• said horizontal partition wall 4 extends over the entire width of said apparatus forming on the side of said door 1, with the latter in closed position, an impassable obstacle between said compartments 2, 3, and that said horizontal partition wall 4 extends in depth up to said vertical partition wall 6. At least in the one of said compartments 2, 3, in particular embodiment in the upper compartment 2, and in the area above and/or below said horizontal partition wall 4 there is provided a cut-out 13 in said vertical partition wall 6, said cut-out 13 penetrating said partition wall 6 and fluidly connecting the compartment 2 with said spacing and channel 7, respectively.
• said cut-out 13 is encased by a body 14 of the blower 14', wherein said body 14 being provided with a grid 15 for entering and/or exiting the cooling air.
• Said body 14 is connected by means of a channel 16 formed in the vertical partition wall 6 with a second compartment, in particular embodiment with the lower compartment 3, in order to said channel 16 fluidly connects through said body 14 and said cut-out 13 the lower compartment 3 and said spacing and channel 7, respectively.
• said vertical partition wall 6 is provided with an air slit 17 for entering and/or exiting the cooling air.
• An aperture 18 for the cooling air flow is provided in the lowermost area of the vertical partition wall 6, between the latter and the body of the cooling and/or freezing apparatus according to the invention.

In this first position, the cooling air streams around said drawer 11 from the outside thereof only. However, when the user wants to change the microclimate in said drawer 11, the user pulls said displaceable shelf 12 towards the door 1 so that a gap is created between said vertical wall 6 and said shelf 12 through which gap the cooling air can flow into said drawer 11.
• the cooling and/or freezing apparatus comprises a plurality of temperature sensors, at least one temperature sensor 20, 21 being placed in each said compartment 2, 3, and at least one temperature sensor 22, 23 being placed either in the immediate vicinity of each evaporator 8, 9 or directly on said evaporator 8, 9, said temperature sensors detect and monitor the temperature in said compartments 2, 3.
• said temperature sensors 20, 21; 22, 23 act by a control unit 24 upon a valve 25 in a cooling loop, said valve either reduces or increases the refrigerant inflow into the evaporator 8, 9 of each compartment 2, 3.
