Definitions

  • the invention relates generally to an air duct. More specifically, the invention relates to an air duct for a refrigerator. The invention also relates to a refrigerator including the air duct.
  • a refrigerator includes an enclosure that is suitable for keeping the contents stored therein within a prerequisite range of temperatures, and are commonly used to store products such as food and beverages.
  • the refrigerator includes an air duct to direct cooling air from a fan of a refrigeration system into the enclosure.
  • An example of a known refrigerator 52 with an air duct 2 is shown in Figure 1 .
  • the refrigerator 52 has a refrigeration system 60 with a fan that directs cooling air along a passage 62 in a direction denoted by the arrow 'A' towards the air duct 2.
  • the air duct 2 directs the cooling air along a direction denoted by the arrow ⁇ B' along the upper surface 56 of the enclosure 54.
  • the refrigerator 52 includes shelves 58 that are provided to hold products such as food or beverages.
  • the air duct 2 provides a circulation of cooling air inside the enclosure of the refrigerator 52.
  • the products that are located at a downstream position of the circulation are cooled less than the products that are located at an upstream position of the cooling air. This results in a large temperature spread of products depending on where the products are located within the refrigerator 52.
  • the present invention provides at least an alternative to air ducts and refrigerators of the prior art.
  • an air duct for a refrigerator having an enclosure and a refrigeration system with a fan for generating a cooling airflow, the air duct comprising:
  • cooling airflow from the refrigeration system is directed by the air outlet into the enclosure in a first direction to cool the enclosure along the first direction, while a portion of the cooling airflow is diverted in a different second direction towards a different part of the enclosure of the refrigerator.
  • This improves the distribution of cooling air within the enclosure so that the temperature is more evenly distributed, reducing the temperature spread of products when they are placed within different parts of the enclosure.
  • the required average temperature is reached faster to sufficiently cool the products within the enclosure, so that less energy is used to cool the refrigerator.
  • the first direction is parallel to an upper surface of the enclosure.
  • the air duct and the upper surface of the enclosure define a channel.
  • the second direction is parallel to an upper surface of the enclosure.
  • the second direction is sideways relative to the first direction.
  • the cooling air is spread to more parts of the enclosure, improving the temperature distribution within the enclosure.
  • the second direction is downwards relative to the first direction.
  • the cooling air is spread to more parts of the enclosure, improving the temperature distribution within the enclosure.
  • the second direction is towards the door of the refrigerator.
  • the second direction is towards the back of the enclosure.
  • the diverter comprises a plurality of openings.
  • the diverter comprises one or more louvre vents.
  • the louvre vent(s) comprises a plurality of blades. In examples, at least two of the blades point in different directions.
  • the air duct further comprises a duct body between the air inlet and the outlet.
  • the duct body comprises an inlet body portion adjacent the air inlet.
  • the duct comprises an outlet body portion adjacent the air outlet.
  • the outlet body portion of the duct body is parallel to the upper surface of the enclosure of the refrigerator.
  • the duct body comprises an inlet body portion adjacent the air inlet and an outlet body portion adjacent the air outlet.
  • the inlet body portion and the outlet body portion are adjoined by a folded portion.
  • an obtuse angle is formed between the inlet body portion and the outlet body portion.
  • At least a portion of the duct body is planar.
  • the air duct further comprises a fan mounting plate adjacent the air inlet.
  • the fan mounting plate comprises at least one opening configured for receiving a fan.
  • a refrigerator comprising:
  • the refrigerator includes the air duct of the present invention and therefore provides the same advantages as described above.
  • the enclosure comprises a first side. In examples, the enclosure comprises a second side opposite the first side. In examples, the enclosure comprises an upper surface. In examples, the enclosure comprises a back surface. In examples, the enclosure comprises at least one door opposite the back surface. In examples, the air duct is arranged on the upper surface of the enclosure. In examples, the refrigerator system is arranged on the first side of the enclosure. In examples, the air outlet is directed towards the second side of the enclosure.
  • the diverter of the air duct diverts a portion of the cooling airflow towards the door.
  • the door is proximal to the first side.
  • the diverter of the air duct diverts a portion of the cooling airflow into the enclosure towards the back surface of the enclosure.
  • the refrigerator is a back bar refrigerator appliance.
  • a back bar refrigerator appliance is typically sized to fit within a cavity or recess behind a bar, for example under a worksurface and/or between opposing walls.
  • the terms 'connected', 'attached', 'coupled', 'mounted' are intended to include direct connections between two members without any other members interposed therebetween, as well as, indirect connections between members in which one or more other members are interposed therebetween.
  • the terminology includes the words specifically mentioned above, derivatives thereof, and words of similar import.
  • the air duct 102 has an air inlet 104 and an air outlet 106.
  • the air outlet 106 is arranged downstream of the air inlet 104 such that a cooling airflow can be directed from the air inlet 104 to the air outlet 106 in use.
  • the air duct 102 When applied to a refrigerator, the air duct 102 is positioned in the top of the enclosure and defines a channel (i.e. path) between the wall of the air duct 102 and the upper surface of the refrigerator enclosure.
  • the air duct 102 has a diverter 108 arranged between the air inlet 104 and the air outlet 106.
  • the diverter 108 is arranged to divert some of the cooling airflow in use, such that instead of moving from the air inlet 104 to the air outlet 106 in a first (i.e. primary) direction, it is instead bypassed and diverted in a second direction away from the air outlet 106 that is different from the first direction.
  • the first direction may be across the upper surface of the enclosure.
  • the second direction may be towards the front (e.g. door) of the refrigerator.
  • the second direction may instead be towards the back of the refrigerator.
  • the second direction may be parallel to the upper surface of the enclosure.
  • the second direction may instead be non-parallel with the upper surface of the enclosure, for example in a direction downwards relative to the first direction.
  • cooling air is supplied by a refrigeration system (160, Figure 8 ) with a fan.
  • the details of the refrigeration system 160 may be entirely conventional so will not be described.
  • the air duct 102 in this example has a body 120 with two parts.
  • the body 120 of the air duct 102 is shown without the diverter 108 in Figure 3 .
  • the body 120 of the duct 102 has an inlet body portion 120a adjacent the air inlet 104, and an outlet body portion 120b adjacent the air outlet 106.
  • the inlet body portion 120a has a planar surface, angled relative to the air inlet 104.
  • the outlet body portion 120b is also planar in this example, and is angled relative to the inlet body portion 120a.
  • a fold 122 is provided between the inlet body portion 120a and the outlet body portion 120b, forming an obtuse angle. In this example, the angle between the inlet body portion 120a and the outlet body portion 120b is 120 degrees.
  • the sides of the inlet body portion 120a are provided with raised edges 124 that prevent the cooling airflow from escaping the air duct 102 as it moves across the inlet body portion 120a.
  • a side of the outlet body portion 120b is provided with a recessed side surface 121.
  • a main surface of the diverter 108 is placed onto the outlet body portion 120b, and an engaging surface 112 of the diverter 108 rests against the inlet body portion 120a to hold the diverter 108 in place between the air inlet 104 and the air outlet 106.
  • the diverter 108 is provided with an aperture 127 through which a fastener can be inserted to fasten the diverter 108 to the body 120 of the air duct 102.
  • the diverter 108 is also provided with another aperture 115 through which another fastener can be inserted to fasten the diverter 108 and air duct 102 to an inner surface of a refrigerator.
  • the diverter 108 has a louvre vent 110 that allows for the passage of air from one side to the other.
  • the blades of the louvre vent 110 alternate such that adjacent blades point in different directions (see Figure 4(a) ).
  • a distal side of the diverter 108, downstream of the louvre vent 110, is provided with a raised edge 114 that extends upward perpendicular to the outlet body portion 120b.
  • the diverter 108 is injection moulded and is formed of polypropylene, but may alternatively be made from sheet metal.
  • the air duct 102 is provided with a fan mounting plate 116.
  • the fan mounting plate 116 is shown in isolation from the rest of the air duct 102 in Figure 5 .
  • the fan mounting plate 116 is provided with two openings 118 into which fans are mounted to draw cooling air through the air inlet 104 from the refrigeration system (160, Figure 8 ). It is envisaged that a different number of openings 118 may be provided in the mounting plate 116, depending on the number of fans to be mounted.
  • the fan mounting plate 116 is positioned between the air inlet 104 and the inlet body portion 120a.
  • the air duct 102 is attached to the upper surface of the enclosure of the refrigerator by inserting a fastener through the aperture 115.
  • the outlet body portion 120b is arranged substantially parallel to the upper surface of the enclosure.
  • the diverter 108 is positioned to divert cooling airflow received by the air inlet 104 such that instead of being entirely directed towards the air outlet 106 in a first direction towards the enclosure, a portion of the cooling air is instead diverted away in a second direction towards the enclosure, the second direction being different from the first direction.
  • the cooling air is diverted in a second direction towards the recessed side surface (121, Figure 3 ) of the air duct body 120.
  • the second direction may be towards another part of the enclosure, so long as it is a different direction to the first direction.
  • Cooling air is drawn through the air inlet 104 from the refrigeration system 160, primarily in a first direction towards the air outlet 106 along a flow path denoted by the arrows 'C' and 'D'.
  • a portion of the cooling air closer to the diverter 108 i.e. along the flow path direction 'C' is diverted by the diverter 108 towards the louvre vent 110 of the diverter 108, in a downward direction relative to the first direction, along a second direction denoted by the arrow 'E', as seen in Figure 8 .
  • the diverter 108 may instead, or in addition, divert the airflow in a direction sideways relative to the first direction.
  • the diverter 108 By diverting the airflow in a second direction different from the first direction using the diverter 108, instead of all the cooling airflow being directed downstream towards the air outlet 106, a portion of the cooling airflow is diverted in a different direction. This improves the distribution of cooling airflow, and therefore, temperature, within the enclosure of the refrigerator.
  • the blades of the louvre vent 110 are arranged in an alternating manner such that adjacent blades point in different directions, which further distributes the cooling air within the enclosure of the refrigerator. This is because the cooling air diverted by the alternating blades is directed in different directions, and therefore towards different prats of the enclosure.
  • the refrigeration system 160 has a fan that supplies cooling air along a passage 162 in a direction denoted by the arrow 'A' towards the air inlet 104 of the air duct 102.
  • One or more fans may be provided in the air duct 102 to draw the cooling air into the air duct 102.
  • the air duct 102 directs the cooling air along a direction denoted by the arrow ⁇ B' along the upper surface 156 of the enclosure 154. As the cooling air travels along the upper surface 156 of the enclosure 154, it gradually falls into the enclosure to create an air circulation that is concentrated along the upper surface 156 and the lower surface of the enclosure 154.
  • the coldness of the air is transferred to the products held within the shelves 158 as it falls to cool those products, such that the air at the lower surface of the enclosure 154 is warmer than the air at the upper surface 156 of the enclosure 154. If a diverter 108 is not provided then the products lower in the enclosure will be cooled to a lesser extent than the products higher in the enclosure. The diverter 108 diverts a portion of the cooling air so that instead of exiting from the air duct 102 from the air outlet 106, the cooling air is diverted by the diverter 108 in a direction denoted by the arrow 'E'.
  • the diverter 108 diverts a portion of the cooling air downward towards a lower part of the enclosure 154 away from the upper surface 156 of the refrigerator 152.
  • the diverter 108 may divert the cooling air towards the door, which may then reflect the cooling air to a different part of the enclosure 154.
  • the diverter 108 may divert the cooling air towards a side of the enclosure away from the air outlet 106, for example to a portion of the enclosure 154 proximal the passage 162.
  • the diverter 108 may include a bend to direct the air towards to a part of the enclosure 154 that requires cooling, for example towards the lower surface of the enclosure 154.
  • the diverter 108 may divert the cooling air downwards.
