Definitions

  • the present invention relates to a refrigeration appliance, in particular a household refrigeration appliance such as a refrigerator, a freezer, a chest freezer or a fridge-freezer combination.
  • a compressor and a condenser are often arranged together in a machine room, with the machine room typically being arranged on a bottom end of the refrigeration device.
  • This can result in dust, hair or other household dirt getting from the floor where the refrigeration unit is installed into the machine room and getting caught on the condenser, e.g. on the fins or pipe sections of the condenser. This impairs the heat transfer between the condenser and the ambient air and can therefore lead to an increase in the energy consumption of the refrigeration device.
  • the document CN 207197050 U discloses a household refrigerating appliance with a refrigeration compartment, a machine room separated from this and a refrigeration cycle for cooling the refrigeration compartment with a compressor and a condenser which are arranged next to one another in the machine room.
  • An air inlet in fluid communication with the machine room is arranged above the machine room with respect to the direction of gravity and an air outlet is arranged on the side of the machine room at ground level. This is to avoid soil being sucked from the floor into the machine room to reduce condensing contamination of the condenser.
  • a refrigeration appliance according to the invention which in particular can be a household refrigeration appliance such as a refrigerator, a freezer, a chest freezer or a fridge-freezer combination, comprises a refrigeration compartment, a machine room which is delimited in relation to a vertical direction by a machine room floor and a ceiling wall and a air inlet arranged in the area of the machine room floor and an air outlet arranged in the area of the ceiling wall, and a cooling circuit in which a refrigerant can be circulated.
  • the cooling circuit comprises an evaporator thermally coupled to the refrigeration compartment for dissipating heat from the refrigeration compartment, a compressor arranged in the machine room in the area of the machine room floor for compressing and circulating the refrigerant and a condenser arranged in the machine room in relation to the vertical direction above the compressor for dissipating heat the environment.
  • One idea on which the invention is based consists in arranging a condenser above the compressor in a machine room arranged at a bottom end of the refrigerating appliance.
  • the machine room is thus delimited by a machine room floor, which can simultaneously form a floor of the refrigeration device or is located facing a floor of the refrigeration device, and a machine room ceiling, which is arranged opposite the floor in relation to a vertical direction.
  • the bottom of the refrigeration device can have feet or the like, for example.
  • the compressor and an air inlet, through which ambient air can be fed into the machine room, are arranged in the area of the machine room floor, while the condenser is arranged at a distance from the compressor in the vertical direction and an air outlet, through which air can be discharged from the machine room into the environment, is spaced apart from the air inlet in the vertical direction.
  • the refrigeration device is set up on a mounting base, for example a floor or a cupboard floor
  • the machine room floor faces the mounting base and the machine room ceiling faces away from the mounting base.
  • the vertical direction extends along the direction of gravity.
  • the arrangement of the condenser in relation to the vertical direction above the compressor further supports the separation of dirt particles by gravity.
  • the arrangement of compressor and condenser according to the invention can reduce contamination of the condenser, as a result of which the cooling circuit works with high efficiency over a long period of time. It also extends the life of the device.
  • the machine room can be a room defined by the ceiling wall or the machine room ceiling and the machine room floor as well as by several side walls, which is spatially or structurally separated from the refrigeration compartment.
  • the refrigeration compartment can be defined by a refrigeration compartment container, wherein the refrigeration compartment container can be formed by a trough-shaped plastic part, for example.
  • the refrigeration compartment container and the machine room can optionally be connected in a fluidically conductive manner, e.g. by a piece of pipe.
  • an intermediate floor is arranged, which extends transversely to the vertical direction from a first side wall of the machine room, and between an end of the Intermediate floor and a second side wall of the machine room, which is opposite the first side wall, a gap is formed.
  • an intermediate floor that extends in a depth direction, for example in the form of a plate, is provided.
  • the depth direction extends transversely to the vertical direction.
  • the intermediate floor can extend over the entire width of the Machine room extend.
  • a gap is formed between an end remote from the first side wall with respect to the depth direction and the second side wall, as a result of which the flow is deflected or generally influenced. This can further improve the separation of dirt particles.
  • the air inlet and the air outlet are formed in the first side wall.
  • air inlet and air outlet are arranged opposite to the gap with respect to the depth direction. This results in a labyrinthine routing of the flow from the air inlet, through the gap and via the condenser to the air outlet. Changing the flow direction further improves the separation of dirt particles from the air.
  • an air guiding projection protruding in the direction of the machine room floor is arranged at the end of the intermediate floor.
  • the air conduction jump can be formed, for example, by a web extending transversely, in particular perpendicularly, to the intermediate floor in the vertical direction. This further improves the separation of dirt particles from the air.
  • the air outlet has a flow guide structure, which is designed to guide a flow emerging from the engine room through the air outlet away from the air inlet.
  • the flow guide structure thus deflects the flow away from the machine room floor when air flows from the machine room through the air outlet into the environment. This counteracts a flow short circuit between the air outlet and the air inlet, which further improves the efficiency of the cooling circuit.
  • the flow guide structure of the air outlet is formed by one or more guide plates or lamellae that are inclined with respect to the vertical direction.
  • the first side wall can have a multiplicity of slits or openings, which are delimited by slats with respect to the vertical direction.
  • the slats or metal sheets are so arranged and inclined to direct flow exiting the engine room through the air outlet away from the air inlet.
  • the air inlet has a flow guide structure, which is designed to guide a flow from an area remote from the air outlet into the engine room.
  • a flow guide structure which is designed to guide a flow from an area remote from the air outlet into the engine room.
  • the flow guide structure of the air intake causes air to be drawn into the engine room from a floor-side area. This counteracts a flow short circuit between the air outlet and the air inlet, which further improves the efficiency of the cooling circuit.
  • the flow guide structure is formed by one or more guide plates or lamellae that are inclined with respect to the vertical direction. The slats can be designed in the same way as those of the air outlet, but are inclined in the opposite direction.
  • the refrigeration device has an outer projection provided between the air inlet and the air outlet in relation to the vertical direction, which protrudes from an outer side of the machine room in a depth direction running transversely to the vertical direction.
  • the outer projection can be formed, for example, by a ridge which projects in the depth direction from the first side wall.
  • the optional shelf and outboard projection may be provided on opposite surfaces of the sidewall.
  • the outer projection can optionally extend over the entire width of the machine room and further optionally over the entire width of the refrigeration device.
  • the outer projection forms a flow barrier and thus further counteracts a flow short circuit between the air outlet and the air inlet.
  • the outer projection can act as a spacer to a wall on which the refrigeration device can be arranged. This counteracts unintentional covering of the air inlet and air outlet.
  • the refrigeration device has an evaporation tray arranged in the machine room in the area of the air inlet for receiving condensed water from the refrigeration compartment.
  • the evaporation tray is arranged with respect to the vertical direction below the compressor. Due to the flow guidance within the machine room with the air inlet arranged in the lower area, air flows between the compressor and the evaporation tray, as a result of which a particularly efficient evaporation of condensed water that collects in the tray takes place.
  • the refrigeration device has a fan which is arranged in an upper region of the machine room in relation to the vertical direction and is set up to suck air into the machine room through the air inlet and expel it through the air outlet.
  • a heat exchange between the condenser and the environment can be further improved. Since the fan is located in the upper area of the machine room, e.g. above the optional intermediate floor, dirt particles are separated relatively reliably.
  • the condenser has a line arrangement and that the fan is arranged or positioned for transporting air via the line arrangement.
  • the line arrangement can be arranged between the air outlet and the fan. Air can be sucked in by the fan through the air inlet arranged below, with the arrangement of the condenser at the top in the machine room effectively counteracting contamination of the line arrangement despite relatively high air throughputs.
  • the condenser has a large number of cooling elements, in particular in the form of wire rods or fins, which are in contact with the line arrangement and optionally mechanically connected to it, for example welded.
  • the condenser can be implemented as a so-called MCHE condenser, "MCHE” being the abbreviation for the English expression "Micro Channel Heat Exchanger”.

  • Such condensers are relatively compact with high heat exchange efficiency.
  • the machine room is arranged at a lateral end of the refrigeration device in relation to a width direction extending transversely to the vertical direction and extends only over a part of the refrigeration device in relation to the width direction, and wherein a refrigeration compartment with respect to the width direction extends laterally of the machine room.
