Description
- 1. Field of the Invention
- The present invention relates to a blower assembly for use with HVAC modules for passenger vehicles.
- 2. Description of the Background Art
- 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.
- 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 instance, U.S. Pat. No. 6,347,746 provides an aspirator connected to a temperature/humidity sensor, the aspirator being connected to the HVAC housing downstream of the blower mechanism, whereby air is drawn from the temperature/humidity sensor to the HVAC housing. See, also, U.S. Pat. No. 6,116,511, which discloses the presence of an aspirator connected to a temperature sensor, whereby air is drawn from the HVAC housing over the temperature sensor via a venturi.
- Aspirators are accordingly generally mounted within a high pressure area, such that air is moved through a tube that passes by another opening which causes suction on the opening. 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.
- It is therefore an object of the present invention to provide a blower assembly for use with an HVAC module.
- 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 shaft, the shaft extending along a central axis of the air inlet of the housing. At least one venturi is provided and is adjacent to the air inlet of the housing and is in fluid communication with a sensor unit, whereby, in operation, the blower wheel pulls air both through the air inlet to the housing and through the at least one venturi.
- Further, scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

FIG. 9 is a top view of the upper housing embodiment ofFIG. 10 depicting a multiple venturi embodiment; and -
FIG. 10 is a view in perspective of the blower assembly of the present invention having multiple venturis. - The blower assembly of the present invention will be described further below in conjunction with the Figures.
- 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.
- 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. Thehousing 3 has anair inlet 5 and anair outlet 7, whereby multiple air inlets or air outlets can be provided. The housing may be formed, for example, by securing together mating sides to form the housing. - The blower assembly 1 has a
blower wheel 9 secured to a rotating motor-drivenshaft 11. The shaft extends along a central axis ofinlet 5 in the housing. - The scroll-
shaped housing 3 has anaxial air inlet 5 in aside wall 15 of the housing. Theair inlet 5 provides air to be blown by theblower wheel 9. Thehousing 3 also has anair outlet 7 through which the blown air passes from the housing in a generally tangential manner. - In accordance with an embodiment of the present invention, at least one venturi is provided at a position adjacent to the
air inlet 5, with the at least one venturi connected to an aspirator tube in communication with a sensor, such as a temperature sensor. - In one embodiment, as depicted in
FIG. 1 , a separateouter air chamber 17 is circumferentially positioned about theair inlet 5. Theouter air chamber 17 has anair inlet 19 connected to anaspirator 21, and at least one air outlet in the chamber comprising at least one venturi opening 25 adjacent theair inlet 5. Theaspirator 21 is in fluid communication with a sensor, such as a temperature sensor (not shown).Chamber 17 may havemultiple venturi openings 25 spaced about the circumference of theair inlet 5 as shown inFIG. 9 . Alternatively, the venturi opening 25 may comprise an annular opening extending about the circumference of theair inlet 5 as shown inFIGS. 4 and 8 . Multiple aspirators may also be employed connected both to the sensor as well as being spaced about the circumference of theair inlet 5 as shown inFIG. 10 . The particular design of the venturi opening is not critical to practice of the present invention, with the exception that the venturi opening be positioned sufficiently close to the perimeter of theair inlet 5 for the desired venturi effect to be achieved. The venturi opening(s) are of sufficient dimension to provide the desired rate of air flow across the sensor. Also, whileair inlet 5 is shown to be circular, it may be of any suitable geometric configuration which permits sufficient air flow into the housing. - The
blower wheel 9 may be of any suitable configuration. Preferably, as depicted inFIG. 3 , the blower wheel comprises a centrifugal blower impeller having acentral hub 27 mounted on the rotating motor-drivenshaft 11. The impeller has a centralconical section 13 extending downwardly and outwardly from the central hub and terminating at an outercircumferential edge 29.Impeller blades 31 extend upwardly from theedge 29, terminating atcircumferential rim 33. The blades may either be restrictedly confined by thecircumferential rim 33 such that the ends of the blades may move within the rim, or the ends of the blades may be fixed to the rim. The blades can be inclined with respect to each other such that air is caused to be drawn into the housing upon rotation of the blades onshaft 11. The blower wheel (and impellers) may be of any suitable configuration which permits air to be drawn into the housing and forced out of the housing as discussed above. One of ordinary skill in the art can readily arrive at a suitable configuration for the blower wheel and impellers. - The
shaft 11 is driven by a suitable motor, which motor is generally placed within the housing adjacent the end of the shaft. The motor can be connectable to a speed control unit for controlling the motor and/or a speed of the motor. - In operation, when driven by the associated motor, motor-driven
shaft 11 causes the blower wheel to rotate at a pre-selected speed. Upon rotation of the blower wheel, air is caused to be drawn axially intoair inlet 5. Air is accordingly also drawn into theventuri opening 25 via theaspirator 21. Air drawn into the housing is then forced radially outwardly between the blower and the interior of the housing, ultimately exiting tangentially throughoutlet 7 of the housing. - As the air is caused to pass over an evaporator core (not shown) associated with the HVAC module, heat is removed from the air passing over the core. Also, as air is caused to pass over a heater core associated with the HVAC housing, heat is added to the air passing over the core. Various other modes may be employed, such as a control door to control a mix of hot and cold air to result in a desired vehicle interior temperature. In addition, various temperature sensors may be employed at various locations in the HVAC module in connection with various climate control strategies. The blower housing is thus in fluid communication with a source of exterior air as well as with the interior of the vehicle for circulating outside air into the interior, or for recirculating air within the vehicle in a recirculation mode.
- The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
