Definitions

  • the refrigerant can be prevented during the compression phase of the compressor from flowing back towards the evaporator and heating up, expanding in the suction tube and the evaporator.
  • the amount of refrigerant that remains trapped inside the cavity during the compression phase also becomes comparatively higher. Thereby, a comparatively larger amount of refrigerant can be sucked out of the cavity into the cylinder bore during the suction phase of the compressor, and thus the volumetric efficiency of the compressor can be increased.
  • the one-way valve unit comprises a flexible leaf as a valve member that is attached to the inner surface of the casing so as to entirely cover the inlet port at the rest position.
  • the flexible leaf is made of a heat-resistant flexible material.
  • the flexible leaf can be made, for instance, from rubber. Alternatively metal can be used. Also composite materials can be used so as to reduce the risk of fatigue failures.
  • the stiffness of the flexible leaf is kept relatively small such that the inlet port easily re-opens at a relatively small differential pressure during the suction phase, but closes sufficiently tightly during the compression phase.
  • the suction muffler (1) comprises a casing (3), a cavity (4) inside the casing (3), an inlet port (5) for admitting the refrigerant into the cavity (3) and an outlet port (6) for discharging the refrigerant out of the cavity (3) ( Fig. 1 to 4 ).
  • the refrigeration appliance (not shown) of the present invention comprises the hermetically sealed compressor (2).
  • the attachment means (10) comprises a retaining slot (13) which is disposed into the inner surface (11) of the casing (3).
  • the edge (14) of the flexible leaf (9) is clamped into the retaining slot (13) ( Fig. 1 to 3 ).
  • the compressor (2) is hermetically sealed through the upper casing (19) and the lower casing (20).
  • the lower casing (20) serves as the lubricant sump (21).
  • An oil pickup-tube (22) is partly immersed into the lubricant sump (21).
  • the motor (23) has a stator (24) and a rotor (25).
  • the crankshaft (26) is journalled into the main bearing (27) of the cylinder block (28).
  • the rotor (25) is fixed around the crankshaft (26).
  • the suction muffler (1) is mounted onto the cylinder head (33) such that the outlet port (6) is located immediately upstream of the valve plate (36).
  • the casing (3) of the suction muffler (1) has a drainage opening (not shown) for draining the lubricant into the sump (21).
  • the volumetric efficiency of the hermetically sealed compressor (2) can be increased in a cost-effective way. Also with the suction muffler (1) of the present invention, the noise level of the hermetically sealed compressor (2) can be reduced in a cost-effective way.

Claims (8)

  1. Ein Kühlgerät, insbesondere ein Haushaltskühlgerät umfasst einen hermetisch abgeschlossenen Kompressor, einen Verdampfer und einen Kältekreislauf für das Umwälzen des Kältemittels über den hermetisch abgeschlossenen Kompressor (2) mit einem Ansaugschalldämpfer (1), weiterhin umfasst er:
    - einen Körper (3);
    - einen Hohlraum (4) innerhalb der Gehäuse (3),
    - eine Einlassöffnung (5), die über ein Saugrohr mit dem Verdampfer verbunden ist, damit das Kältemittel in den Hohlraum (3) eingelassen wird,
    - eine Auslassöffnung (6) zum Ablassen des Kältemittels aus dem Hohlraum (3), und
    - eine Rückflussverhinderungsvorrichtung (7), die in dem Hohlraum (3) des Ansaugschalldämpfers (1) angeordnet ist und dafür konfiguriert ist, um einen Rückfluss des Kältemittels durch die Einlassöffnung (5) aus dem Hohlraum (3) zum Verdampfer zu verhindern, wobei die Rückflussverhinderungsvorrichtung (7) eine Einwegventileinheit (8) umfasst, die konfiguriert ist, um die Einlassöffnung (5) zu öffnen, wenn sich der Kompressor (2) in der Saugphase befindet, und weiterhin konfiguriert ist, um die Einlassöffnung (5) zu schließen, wenn der Kompressor (2) sich in der Kompressionsphase befindet,
  2.

  5. Das Kühlgerät, wie in Anspruch 1 oder 2 aufgeführt, ist dadurch gekennzeichnet, dass das Befestigungsmittel (10) mindestens zwei Stifte (15) aufweist, die auf der Innenfläche (11) des Gehäuses (3) angeordnet sind, wobei das flexible Blatt (9) Gegenlochungen (16) aufweist, damit es jeweils mit den Stiften (15) zusammenpasst.
  6. Das Kühlgerät, wie in Anspruch 5 aufgeführt, ist dadurch gekennzeichnet, dass das Befestigungsmittel (10) einstückig mit dem Gehäuse (3) ausgebildet ist.
  7. Das Kühlgerät, wie in Anspruch 6 aufgeführt, ist dadurch gekennzeichnet, dass das Gehäuse (3) einen oberen Teil (3a) und einen unteren Teil (3b) aufweist, die lösbar aneinander befestigbar sind, wobei die Auslassöffnung (6) in dem oberen Teil (3a) angeordnet ist und die Einlassöffnung (5) in dem unteren Teil (3b) angeordnet ist.
  8. Das Kühlgerät, wie in einem der vorherigen Ansprüchen aufgeführt, ist dadurch gekennzeichnet, dass die Einlassöffnung (5) und die Auslassöffnung (6) entlang einander quer verlaufender Richtungen ausgerichtet sind.
