Stand der TechnikState of the art

Die Erfindung geht aus von einem Belüicungsgeuläse nach der Gattung des Hauptanspruchs. Bei einem derartigen vorangemeldeten Belüftungsgebläse/ wie es beispielsweise für die Klimaanlage eines Kraftfahrzeugs verwendet wixd, kann mit Hilfe des Temperatursensors lediglich die Lufttemperatur im Fahrzeuginnenraum beeinflußt werden. Dies genügt jedoch bei besonderen Anforderungen an den Klimakcmfort nicht mehr, da auch andere Einflüsse eine Rolle spielen.The invention is based on a ventilation fan according to the type of the main claim. In a previously registered ventilation fan such as is used for the air conditioning system of a motor vehicle, only the air temperature in the vehicle interior can be influenced with the help of the temperature sensor. However, this is no longer sufficient for special requirements for air conditioning comfort, since other influences also play a role.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Belüftungsgebläse mit den kennzeichnenden Merkmalen hat demgegenüber den Vorteil, daß es bei nur geringfügig höherem Aufwand einen wesentlich besseren Klimakomfort schafft. Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung und Zeichnung.The ventilation fan according to the invention with the characteristic features has the advantage that it creates significantly better climate comfort with only slightly higher expenditure. Further advantages of the invention emerge from the subclaims, the following description and drawing.

Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der nachfolgenden Beschreibung und Zeichnung wiedergegeben. Letztere zeigt einen Teillängsschnitt durch ein Belüftungsgebläse.An embodiment of the invention is shown in the following description and drawing. The latter shows a partial longitudinal section through a ventilation fan.

Beschreibung der ErfindungDescription of the invention

Das Belüftungsgebläse besteht aus einem ein- oder mehrteiligen Gehäuse 10, in dessen oberem Teil ein elektrisch kommutierbarer Motor 11 angeordnet ist., welcher siis Li:r:errad 12 antreibt/ das unmittelbar unterhalb des Motors 11 angeordnet ist, aber am oberen Ende eines Ansaugstutzens 13, durch welchen ein Luftstrom L in axialer Richtung des Lüfterrads angesaugt wird, in dem er umgelenkt wird und das Gehäuse 10 in radialer Richtung verläßt, siehe die Pfeile P.The ventilation fan consists of a one- or multi-part housing 10, in the upper part of which an electrically commutable motor 11 is arranged, which drives a fan wheel 12 which is arranged immediately below the motor 11, but at the upper end of an intake nozzle 13, through which an air flow L is sucked in in the axial direction of the fan wheel, in which it is deflected and leaves the housing 10 in the radial direction, see the arrows P.

Nahe der Ansaugöffnung 15, welche aus einem an der offenen Stirnseite des Ansaugstutzens angeordneten Einlaßstück 15 besteht, ist ein Temperatursensor 16 beliebiger Art angeordnet· Von ihm führen elektrische Leitungen 17 zu einer Auswerteelektronik 18, welche sich in einem Seitenteil 19 des Gehäuses 10 befindet. In dem Ansaugstutzen 13 ist darüber hinaus in Flußrichtung hinter dem Temperatursensor 16 eine Öffnung 20 ausgebildet, in welcher ein Feuchtigkeitssensor 21 ebenfalls beliebiger Bauart angeordnet ist, dessen Fühlfläche 21A in den Ansaugstutzen hineinragt. Der Feuchtigkeitssensor 'st ebenfalls über elektrische Leitungen 22 mit der Auswerteelektronik 18 verbunden. Auf diese Weis«; erhält die Klimaanlage des Fahrzeugs ständig Signale über die Lufttemperatur am Einlaß und deren Feuchtigkeitsgehalt. Durch entsprechende Auswertung dieser Signale wird das Klimagerät entsprechend beeinflußt, so daß die Innenraumätmosphäre einen gewünsch- ten bzw. optimalen Wert erhält.A temperature sensor 16 of any type is arranged near the intake opening 15, which consists of an inlet piece 15 arranged on the open front side of the intake nozzle. Electrical lines 17 lead from it to an evaluation electronics 18, which is located in a side part 19 of the housing 10. In the intake nozzle 13, an opening 20 is also formed in the flow direction behind the temperature sensor 16, in which a humidity sensor 21 of any type is arranged, the sensing surface 21A of which protrudes into the intake nozzle. The humidity sensor is also connected to the evaluation electronics 18 via electrical lines 22. In this way, the vehicle's air conditioning system constantly receives signals about the air temperature at the inlet and its moisture content. By appropriately evaluating these signals, the air conditioning unit is influenced accordingly, so that the interior atmosphere receives a desired or optimal value.

Auf den konstruktiven Aufbau des Gebläses ist weiter nicht eingegangen, aber wie aus Obigem hervorgehet, handelt es sich bei dem Lüfterrad um einen Radiallüfter. Das Gehäuse 10 kann ein- oder mehrteilig sein und besteht zweckmäßigerweise aus Kunststoff. Es ist an einer Wand- oder Deckenverkleidung 23 - vorzugsweise mit seinem Ansaugstutzen 13 - befestigt.The construction of the fan is not discussed further, but as can be seen from the above, the fan wheel is a radial fan. The housing 10 can be made of one or more parts and is preferably made of plastic. It is attached to a wall or ceiling panel 23 - preferably with its intake nozzle 13.
