Benefits of technology

[0008]In an embodiment, a blower assembly is provided that includes a scroll-shaped housing, the scroll-shaped housing having an air inlet in a wall of the housing for receiving air to be blown by the impeller, and an air outlet from which the blown air passes from the housing. A blower wheel is secured to a rotatable motor-driven s...

Problems solved by technology

Depending on the location of the aspirator on the HVAC module, air (hot or cold) may be blown into the passenger cabin of the vehicle, which is a disadvantage from the standpoint of controlling the environment of the passenger cabin.

Embodiment Construction

[0021]The blower assembly of the present invention will be described further below in conjunction with the Figures.

[0022]The blower assembly of the present invention comprises a portion of an HVAC module of a passenger vehicle. The HVAC module conditions outside air blown into the interior of the vehicle for purposes of heating, cooling or ventilation of the vehicle interior. The module accordingly heats or cools and distributes air within the interior of the vehicle. Such modules are also connected to various sensors, such as temperature or humidity sensors. The interior of the HVAC module is in fluid communication with the temperature or humidity sensor housing. The designs of such HVAC modules are well known to those skilled in the art.

[0023]The blower assembly 1 of the present invention which comprises a portion of an HVAC module is shown in FIG. 1 as having a volute or scroll-shaped housing 3. The housing 3 has an air inlet 5 and an air outlet 7, whereby multiple air inlets or ...

Abstract

A blower assembly for use with an HVAC module is provided. The blower assembly includes a scroll or volute shaped housing having an air inlet in a wall of the housing for receiving air to be blown by an impeller, and an air outlet from which the blown air passes from the housing. A blower wheel is secured to a rotatable motor-driven shaft extending along a central axis of the air inlet. At least one venture is provided adjacent to the air inlet of the housing, the at least one venturi connectable to an aspirator that is in fluid communication with a sensor unit. Wherein, during operation, the blower wheel pulls air both through the air inlet to the housing and through the at least one venturi.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a blower assembly for use with HVAC modules for passenger vehicles.[0003]2. Description of the Background Art[0004]HVAC modules are used in vehicles to control a passenger compartment air temperature. The module generally includes a housing having an air inlet, an air blower, an evaporator, a heater core, air outlets, etc. The HVAC module can accordingly either heat or cool air flow from the exterior of the vehicle to the interior of the vehicle, optionally to be recirculated within the vehicle. HVAC modules, including the heat exchangers used for the evaporator and heater core, as well as the air blower and housing are thus known to one skilled in the art.[0005]HVAC modules may be provided with an aspirator which is adapted to pull air over a temperature sensor of a control head. An aspirator part is separately provided for this purpose and connected to the HVAC module. See, for instanc...
