Description
Letzterer weist einen Verdampfer 6 und einen Schockfrostventilator 7 auf, unter denen ein an zweiThe latter has an evaporator 6 and a shock freeze fan 7 on, among which one to two
sich gegenüberliegenden Seiten8,9 offenes Schockfrostfach 10 angeordnet ist. Dieses liegt mit seiner offenen Seite 8 unter Bildung eines Kanals 11 im Abstand von der Trennwand 2 und mit seiner offenen Seite 9 unter Bildung eines Kanal 12 im Abstand von der benachbarten Wandung des Schrankgehäuses 1.Opposite sides 8,9 open shock freeze compartment 10 arranged is. This is with its open side 8 with the formation of a channel 11 at a distance from the partition 2 and with its open side 9 forming a channel 12 at a distance from the adjacent wall of the cabinet housing 1.
Lager- und Schockfrostraum sind über einen Umluft-Rückströmkanal 13 miteinander verbunden, der unter dem Schockfrostfach 10 vorbeiführt und in den zur Ansaugöffnung des Schockfrostventilators 7 führenden Kanal 12 mündet. In letzterem ist eine um eine untere Drehachse 14 verschwenkbare Pendelklappe 15 angeordnet, deren beiden äußeren Extremstellungen gestrichelt dargestellt sind. In ihrer linken Stellung deckt die Pendelklappe die offene Seite 9 des Schockfrostfaches 10 dichtend ab und gibt somit für die über den Umiuft-Rückströmkanal 13 herangeführte Luft den größtmöglichen Querschnitt des Kanals 12 frei. In ihrer rechten Extremstellung liegt die Pendelklappe 15 an der Wandung des Schrankgehäuses 1 an, so daß für die aus dem Schockfrostfach austretende Umluft der größtmögliche Strömungsquerschnitt zur Verfügung steht. Storage and shock freezing areas are via a circulating air return duct 13 connected to each other, which passes under the shock freezer compartment 10 and into the to the suction opening of the shock freeze fan 7 leading channel 12 opens. In the latter a pendulum flap 15 pivotable about a lower pivot axis 14 is arranged, whose two outer extreme positions are shown in dashed lines. In her left In position, the pendulum flap covers the open side 9 of the shock freezer compartment 10 in a sealing manner from and thus gives the air brought in via the recirculation return duct 13 largest possible cross-section of the channel 12 free. Lies in its extreme right position the pendulum flap 15 on the wall of the cabinet housing 1, so that for the out The circulating air exiting the shock freezer compartment ensures the largest possible flow cross-section Available.
Die neue Anlage arbeitet wie folgt: Wenn Lagerraum 3 und Schockfrostfach 10 in Betrieb sind, arbeiten beide Ventilatoren 5 bzw. 7. In diesem Fall stellt sich innerhalb des Schockfrostraumes 4 eine Kreisluftbewegung ein, wobei die ihre Mittellage einnehmende Pendelklappe 15 der aus dem Schockfrostfach 10 austretenden Luft einen ausreichenden Ausströmquerschnitt freigibt. Gleichzeitig strömt die von dem Lagerraumventilator 5 aus dem Schockfrostraum 4 angesaugte Kaltluft über den Umiurt-Rückströmkanal 13 in den Kanal 12 und hier an der Pendelkappe 15 vorbei zu dem Schockfrostventilator 7. Die in der Zeichnung dargestellte Mittellage der Pendelklappe ergibt sich aus den Drücken der beiden Umluftströmungen. The new system works as follows: If storage room 3 and shock freezer compartment 10 are in operation, both fans 5 and 7 are working. In this case, it is a circular air movement within the shock freeze space 4, with their The central position occupying pendulum flap 15 of the exiting from the shock freezer compartment 10 Air releases a sufficient outflow cross-section. At the same time flows from the storage room fan 5 from the shock freeze room 4 sucked in cold air via the Umiurt return flow channel 13 into channel 12 and here past the pendulum cap 15 the shock freeze fan 7. The Central position of the pendulum flap shown in the drawing results from the pressures of the two circulating air flows.
Wird wegen Erreichung der gewünschten Lagerraumtemperatur der Lagerraumventilator 5 abgeschaltet, dann drückt die aus der offenen Seite 9 des Schockfrostfaches 10 austretende Kühlluft die Pendelklappe 15 in ihre rechte Extremstellung gegen die Wandung des Schrankgehäuses 1. Damit ist der Kanal 12 verschlossen, so daß die Kühlluft nur zu dem Schockfrostventilator 7 strömen kann. Der große Ausströmquerschnitt aus dem Schockfrostfach ergibt optimale aerodynamische Verhältnisse. Used as a storage room fan to achieve the desired storage room temperature 5 is switched off, then the pushes out of the open side 9 of the shock freezer compartment 10 exiting cooling air the pendulum flap 15 in its right extreme position against the Wall of the cabinet housing 1. So that the channel 12 is closed, so that the cooling air can only flow to the shock freeze fan 7. The large outflow cross-section the shock freeze compartment results in optimal aerodynamic conditions.
Soll das Schockfrostfach 10 nicht in Betrieb gehalten werden, wird der Schockfrostventilator 7 abgeschaltet, so daß nur noch der Lagerraumventilator 5 in Betrieb ist. Die aus dem Umiuft-Rückströmkanal 13 in den Kanal 12 eintretende Umluft drückt dann die Pendelklappe 15 in eine dichtende Anlage gegen die offene Seite 9 des Schockfrostfaches 10. Die aus dem Lagerraum 3 kommende Umluft hat somit nicht mehr die Möglichkeit, direkt durch das Schockfrostfach 10 zu strömen und unter Umgehung des Verdampfers 6 von dem Lagerraumventilator 5 wieder angesaugt zu werden. If the shock freezer compartment 10 is not to be kept in operation, is the shock freeze fan 7 switched off, so that only the storage room fan 5 is in operation. The one entering from the circulation return channel 13 into the channel 12 Circulating air then presses the pendulum flap 15 into a sealing system against the open one Page 9 of the shock freezer compartment 10. The circulating air coming from the storage room 3 thus has no longer the possibility of flowing directly through the shock freezer compartment 10 and under Bypassing the evaporator 6 to be sucked in again by the storage room fan 5.
Die Steuerung der Pendelklappe 15 erfolgt somit vollautomatisch unter Vermeidung irgendeines Fremdantriebes lediglich über die Umluft-Druckverhältnisse der Strömungen im Lagerraum bzw. im Schockfrostraum, also über die beiden Ventilatoren 5 und 7. Da die aus dem Lagerraum zurückströmende Luft an den beiden Seiten des Schockfrostfaches 10 vorbeigeführt wird, an denen allein Wärmeeinfall zu verzeichnen ist, kann das Schockfrostfach auch bei nichtarbeitendem Schockfrostventilator als einfaches Lagerfach benutzt werden. The control of the pendulum flap 15 thus takes place fully automatically under Avoidance of any external drive only via the circulating air pressure conditions the currents in the storage room or in the shock freeze room, i.e. via the two fans 5 and 7. Since the air flowing back from the storage room on both sides of the Shock freezer compartment 10 is passed, where only the incidence of heat is recorded the freeze compartment can also be used when the freeze fan is not working simple storage compartment can be used.
