Abstract

A ventilator fan for the air-conditioning system of the interior of a motor vehicle has an electric motor, in particular an electrically commutable motor, which drives a fan wheel (12) mounted on the inner end of an intake (13). A temperature sensor (16) and a humidity sensor (21) arranged in the suction connection piece are effectively connected by electric cables to an electronic evaluation device (18). The air-conditioning system therefore constantly receives accurate data concerning the temperature and humidity of the intake air and adjusts the atmosphere inside the vehicle optimally accordingly.

Description

ventilation fan

State of the art

The invention relates to a ventilating fan according to the preamble of the main claim. In such a pre-registered ventilation fan, as used for example for the air conditioning of a motor vehicle, can only the air temperature inside the vehicle are influenced by the temperature sensor. However, this is no longer sufficient to meet special requirements to the climate comfort, since other factors play a role.

Advantages of the Invention

In contrast, the ventilation fan invention having the characterizing features has the advantage that it provides a much better climate comfort at only slightly higher cost.

Further advantages of the invention will be apparent from the dependent claims, the following description and drawings.

drawing

An embodiment of the invention is shown in the following description and drawings. The latter shows a partial longitudinal section through a ventilation fan. Description of the Invention

The ventilation fan consists of a one- or multi-part housing 10, an electrically commutatable motor 11 is arranged in the upper part thereof, which drives an impeller 12 which is located immediately below the motor 11, but at the upper end of an intake 13 through which a air stream L is sucked in the axial direction of the impeller, where it is redirected and exits the housing 10 in the radial direction, see the arrows P.

Near the suction opening 15, which consists of an element located at the open end of the intake port inlet section 15, a temperature sensor 16 of any type is arranged. By him electrical wires 17 lead to a transmitter 18 which is located in one side part 19 of the housing 10th In the intake port 13 is an opening 20 formed in the flow direction behind the temperature sensor 16, in which a moisture sensor 21 of any type is also disposed, the sensing surface 21A which projects into the intake manifold beyond. The humidity sensor is also connected via electrical lines 22 to the evaluation 18th In this way, the air conditioning system of the vehicle constantly receives signals over the air temperature at the inlet and its moisture content. the air conditioner is influenced accordingly so that the interior atmosphere is given a desired or optimal value th by appropriate evaluation of these signals.

In the structural design of the fan is still not received, but as can be seen from the above, it is at the fan a radial fan. The housing 10 may be single or multiple parts and is expediently made of plastic. It is on a wall or ceiling paneling 23 - preferably with its manifold 13 - fixed.

Claims

claims
