  • DE-A-10 2006 061 091 discloses a household refrigerator according to the preamble of claim 1.
  • the object of the invention is to provide a household refrigerator with an improved refrigerant cycle system.
  • a household refrigerator comprising at least one heat-insulating inner container with a coolable interior, and designed for cooling the interior refrigerant cycle system comprising at least a compressor, a condenser, and an evaporator, which are connected to form the refrigerant circuit system by refrigerant pipelines of which at least two refrigerant pipes each have a Zulaufrohr effetsendabterrorism and of which a further refrigerant pipe has a drain pipe end portion into which the two Zulaufrohr effetsendabroughe open, in the at least one of the two inlet pipe end sections has a pipe section that widens in the flow cross-section.
  • a refrigerant cycle system generally includes at least one compressor, at least one condenser, and at least one evaporator.
  • the refrigerant is first compressed by the compressor, which heats the refrigerant.
  • the compressed, heated refrigerant is cooled in the condenser, wherein it can at least partially pass from a gaseous phase into a liquid phase.
  • the liquefied, cooled refrigerant is then supplied to a throttle, which expands the liquefied, cooled refrigerant into an evaporator.
  • By the compressed refrigerant is expanded, it cools down, whereby the evaporator and evaporator plates coupled to the evaporator plates, evaporator fins are strongly cooled.
  • the evaporator or the evaporator plates or evaporator plates are coupled to at least one coolable interior, so that this interior is cooled.
  • the interior forms a cold room and is used for example for frost-free cooling of refrigerated goods, preferably at temperatures between plus 4 and plus 8 degrees Celsius.
  • the refrigerator can also be designed as a zero-degree compartment, in particular for keeping fresh fruits or vegetables.
  • the interior may form a freezer compartment which generally serves to freeze frozen food at about minus 18 degrees Celsius.
  • the household refrigerator may have at least one freezer compartment and at least one cold room.
  • the freezer compartment and the refrigerator can each be assigned its own evaporator.
  • These at least two evaporators may constitute components of a single refrigerant cycle system, in particular a single compressor refrigerant cycle system.
  • the components of the refrigerant cycle system in particular compressors, evaporators, condenser and throttles and / or expansion valves are generally connected by refrigerant pipelines.
  • one or more branches in the refrigerant cycle system may be necessary.
  • a branch can also be designed as an inlet, in which, for example, two or more inlet pipe end sections open into a common outlet pipe end section.
  • Such a pipe branch or pipe junction can be designed, for example, T-shaped or Y-shaped.
  • Capillary tubes can form chokes in refrigerant cycle systems. Capillary tubes are known and commonly used in household refrigeration appliances. Capillary tubes are characterized by a reduced, in particular greatly reduced, flow cross-section compared to the other refrigerant pipelines.
  • refrigerant from a particularly thin capillary tube is now introduced or injected into a refrigerant pipeline with in particular a significantly larger flow cross section, then the refrigerant expands into the refrigerant pipeline, which may lead to undesired frost spots or unwanted noise developments in the region of the point of introduction.
  • the inflow pipe end section may have a flow cross-sectional course which extends between the pipe section widening in the flow cross-section and an outlet-side front end of the inflow pipe end section or a pipe connection sleeve, a necking-free, in particular constant or even increasing flow profile.
  • the feed pipe can, for example, have a flow cross-section or inside diameter that is constant over its longitudinal course. In the vicinity of the feed pipe end section, this constant flow cross section or inner diameter can expand to a larger flow cross section or inner diameter. In the simplest case, this extension can occur at a discrete point, so to speak, suddenly, or gradually over a distance.
  • the pipe section widening in the flow cross-section can be continuous, in particular conically widening.
  • a pipe section with a constriction-free, in particular constant or even increasing flow cross-sectional profile can follow, in particular before an exit-side front end of the inlet pipe end section is reached.
  • capillary flow cross-section can thus join a pipe section with a cross-sectional widening and the pipe section with a cross-sectional widening can then connect another pipe section with a particular constant enlarged flow cross-section before this pipe assembly opens into the discharge pipe end portion.
  • the pipe section with a constant small, in particular capillary flow cross-section, the pipe section with the cross-sectional widening and the pipe section with the particularly constant enlarged flow cross section can be formed by forming on a one-piece inlet pipe end section, or be composed of individual separate pipe sections, for example by soldering.
  • flow cross-section reductions, in particular constrictions in the flow direction of the refrigerant should at least substantially be avoided, if not completely excluded.
  • the pipe section widening in the flow cross-section can be made widening up to a constant outflow cross-section, in particular an outflow cross-section corresponding to the outflow cross-section of the other inlet pipe end section.
  • the two feed pipe end sections can have the same or at least approximately the same flow cross section at their respective front ends.
  • the pipe section widening in the flow cross section can have a circular flow cross section.
  • a hollow-cylindrical, in particular hollow circular-cylindrical end pipe section can adjoin the pipe section widening in the flow cross-section. All pipe sections can form at least approximately the same wall thickness both have a circular inner wall cross section and a circular outer wall cross-section.
  • the pipe section widening in the flow cross-section can be formed, for example, on a separate pipe connection sleeve, which is attached to the inlet pipe end section, in particular soldered. In other words, this may mean that an intermediate pipe piece is inserted between the actual feed pipe end portion and the drain pipe end portion.
  • the intermediate pipe section may have the pipe section widening in the flow cross section and / or the hollow cylindrical, in particular hollow circular cylindrical end pipe section having a constant flow cross section.
  • the pipe section widening in the flow cross-section can be aligned coaxially with the feed pipe end section. This means that at least substantially the same, in particular the greatest possible distance from the inner walls of the pipe section widening in the flow cross-section, refrigerant exits the front end of the particular capillary feed pipe end section.
  • the inlet pipe end section can be formed, for example, by a capillary, which is adjoined by the pipe section widening in the flow cross section, in particular to which capillary a tube section of a pipe connection sleeve can be connected, which has the pipe section widening in the flow cross section.
  • the tube section can alseisen a uniform inner diameter, which is substantially equal to or only slightly larger than the outer diameter of the capillary.
  • an end portion of the capillary can be prefixed by simply inserting it into the tube section on the tube coupling sleeve. By such prefixing the capillary can be easily connected to the pipe connection sleeve, in particular soldered or glued.
  • the depth can also be set by which the capillary should project into the pipe connection sleeve, in particular into the pipe section widening in the flow cross section.
  • the capillary can thus protrude within the pipe connection sleeve into the conically widening pipe section.
  • exit end face The capillary of the inner wall diameter so not continuously into the widening in the flow cross-section pipe section, but has a jump.
  • different flow conditions can be adjusted.
  • the flow conditions during assembly of household refrigerators can be optimally adjusted or adjusted.
  • the two Zulaufrohr einsendabitese can be used parallel to each other in the drain pipe end portion. As a result, refrigerant enters the downcomer end portion from at least approximately the same direction. In addition, a flow deflection from the Zulaufrohr effetsendabitesen is reduced to the drain pipe end portion to a minimum.
  • the downcomer end portion may be axially aligned in a direction parallel to the axial extent of the downcomer end portions.
  • refrigerant enters the downcomer end portion from at least approximately the same direction.
  • a flow deflection from the Zulaufrohr einsendabitesen is reduced to the drain pipe end portion to a minimum.
  • the drain pipe end portion may have a particularly constant flow cross-section, which is at least not substantially reduced, in particular equal to or even greater in comparison with the sum of the individual flow outlet cross sections of the Zulaufrohr Obersendabitese. As a result, it can be achieved that no large, in particular sudden, pressure changes occur in the transitional region from the inlet conduit end sections into the downcomer end section.
  • a refrigerant cycle system of a household refrigeration appliance can be improved in particular with regard to injection and flow noise.
  • the refrigeration cycle system according to the invention can be used in particular for cooling of freezer rooms and in fridge / freezer combination devices.
  • the refrigerant cycle system can be connected so that refrigerant is injected either in the refrigerator compartment with downstream freezer or directly into the freezer.
  • a tube enclosing the capillary in the course of the capillary tube, which then widens conically, can be inserted into a specially shaped Y-piece into which the connecting tube can then also open.
  • the capillary tube can be located centrally in the injection tube.
  • the flow cross sections are not reduced in advantageous embodiments by the Y-piece and also the flow direction is not significantly deflected.
  • the flow cross sections in the course in the flow direction can not be significantly reduced. As a result, sometimes homogeneous flow conditions can be achieved and consequently flow noise can be reduced.
  • the capillary tube may be arranged centrally in the middle of the tube, so that the injection of the refrigerant does not take place in the vicinity of the inner wall of the injection tube, which could, for example, lead to negative detachment effects, which could be associated with noise. Furthermore, in a cylindrical gap between capillary tube and injection tube, the penetration depth of a solder and / or the position of the capillary can be better adjusted and made stable in terms of manufacturing technology.
