Description
Technical field
This patent disclosure relates generally to the blower assy used in vehicle, and relate more specifically to the adjustable blower assy relevant with HVAC (HVAC) system.
Background technology
Blower assy is the conventional parts of HVAC (HVAC) system of vehicle and is designed to when with commonly known recirculation and fresh mode operation have maximal efficiency/air-flow.But, in the heater mode in fresh pattern, throughput hinders the best heating properties in vehicle possibly through sub-cooled electromotor.Therefore, the amount of the available coolant heated is likely to be not enough to passenger compartment heating to required temperature.Even more, owing to substantial amounts of air adds the passage of heat and outlet typically across less, the noise level in passenger compartment is likely to be breached unsatisfied level in this mode.Accordingly, it would be desirable to a kind of adjustable or adjustable blower assy is so that required throughput can transmit under all operational modes including recirculation and heater mode combination.
Despite the presence of the various solutions for this problem, but the shortcoming that every kind of such solution has its own.For example, it may be possible to the throughput reducing by reducing the speed of the motor/impeller producing air-flow to realize or limiting in heater mode.But, in the case, add such restriction and tend to increasing the disturbance can not guarded against equally and noise, vibration and roughening to control heater throughput.
Alternatively, it is possible to reduce or restriction is applied to the maximum voltage of motor/impeller thus reducing maximum airflow.Although using the method can suitably reduce maximum airflow, but the minimum voltage being applied to motor/impeller still resulting in the throughput wanting/need throughput more than occupant.Minimum voltage is relevant with the minimum revolution per minute of motor, and causes the oversupply of passenger compartment heating to the air of temperature required heating.Even more, between high speed and low speed, the required step arranged is compressed into the point of any difference that automotive occupant is likely between the setting that cannot be distinguished by selecting.
Regulate blower assy so that the other method that can transmit required throughput in all modes of operation is to adjust the spiral case cut-off portion of blower assy.A kind of mode in the spiral case cut-off portion adjusting blower assy is described in inventing the patent documentation of U.S. Patent number No.1,056,813 of artificial McLean.In some cases by controlling the minimum range of cut-off point or blower drum/between spiral case wall and circumference of impeller, McLean expectation is used in the spiral case wall of blower drum and takes turns and have jumbo displacement blower as pressure type aerator between (or impeller).In the blower assy of McLean, the spiral case wall chain connection of spiral case cut-off portion and blower drum allows spiral case cut-off portion to pivot around attachment point.The horizontal part in spiral case cut-off portion is overlapping with the air stream outlet of blower assy or exhaustor, and horizontal part is substantially through air stream outlet.Speed according to motor uses actuator to adjust the minimum range of blower drum/between spiral case wall and circumference of impeller.
Another inventors determined that the different modes in the spiral case cut-off portion adjusting blower assy.The patent documentation of Japanese Patent No. No.2003042097A describes distance or the air gap of the blower drum/between spiral case wall and impeller periphery adjusted in the blower assy used in vehicle.The design present invention overcomes the problem of the low-frequency noise of generation when the air blown out from centrifugal fan is rearwards into fan relating to causing due to the high pressure in the ventilation duct of air conditioner in blowing foot or Defrost operation pattern.In blower assy, it is provided with moveable nose or the spiral case cut-off portion of the cable tractive being attached with model selection bar.Spiral case cut-off portion translates along the spiral case wall of the shell of blower assy.In other pattern, cable by nose or spiral case cut-off portion along spiral case wall towards fan to pusher to reduce the air gap in remaining operational mode.This patent instructs the pressure transducer used according to the pressure being set to sensing air stream outlet to be driven to the linkage replacement cable in mobile spiral case cut-off portion further.That discusses another option is that when being allowed spiral case cut-off portion to be pivoted out by cable tractive thus spiral case ends when changing the size of the air gap the attachment of portion and spiral case wall.The method is similar with the method for McLean.
The present invention relates to a kind of blower assy having and using driver adjustable spiral case cut-off portion, in order to required throughput can be transmitted under all operational modes of vehicle.Advantageously, this allows vehicle operators even at using blower assy under recirculation and heater mode.Up to now, the air velocity in these patterns is too high and cause can not by passenger compartment heating to temperature required.Even more, the design of the present invention avoids the demand to the cable controlled between element installed at blower assy and instrument board and/or linkage, and is not result in the disturbance and noise, vibration and the roughening that increase.

Detailed description of the invention
Referring now to Fig. 1 and 2, it understands the embodiment of blower assy 10 in broad terms, and this assembly 10 has the shell 12 including spiral case wall 14 and sidewall 16,18.Shell is made up by injection moulding, blow molding etc. of the rigid-plastic material being suitable for such as polypropylene etc. in the present embodiment.Equivalently, however can use the metal parts of punching press.Impeller 20 is positioned at shell 12 and is arranged on the output shaft 22 of motor 24.Air is inhaled in impeller 20 by the hole 17 in sidewall 16.As in figure 2 it is shown, motor 24 is installed to shell 12 and output shaft 22 extends to the shell being provided with impeller 20 in the present embodiment.In a feasible embodiment, as known in the art, motor may be mounted in shell and even may be located in the axle making impeller rotate, in order to taking up room of restriction blower assy.
Being in operation, motor 24 makes output shaft 22 rotate, and output shaft 22 correspondingly makes impeller 20 rotate, and produces air-flow (illustrating generally through arrow 26) along gas channel in shell 12.By making impeller 20 motion in shell 12 produce air-flow 26.Air-flow 26 moves through the air gap (A) of the position in contiguous spiral case cut-off portion 28 in gas channel from impeller 20.Such as shell 12, spiral case cut-off portion 28 is forming polypropylene, it is also possible, however, to use other material is for spiral case cut-off portion.Air-flow 26 continued around the spiral case wall 14 of shell 12 before leaving shell at air stream outlet 30 place.Air stream outlet 30 can be attached with shell 12, or can with shell global formation.
As it is shown on figure 3, the distance between impeller 20 and spiral case cut-off portion 28 defines the air gap (A), air-flow 26 is moved through this air gap (A).As is known, when air-flow moves along gas channel and leaves shell 12 at air stream outlet 30 place, the size of this distance or the air gap (A) affects the speed of air-flow.Change spiral case cut-off portion 28 increase relative to the position of impeller 20 or reduce the speed of air-flow 26.
In the present embodiment, driver 32 is vacuum driving device and is installed to shell 12 for making spiral case cut-off portion 28 move.As shown in the action arrow B of Fig. 3, spiral case cut-off portion 28 moves along the protuberance 34 extended from shell.Protuberance 34 extends from the position of the upstream extremity in the contiguous spiral case cut-off portion 28 of shell 12, and in the described embodiment protuberance 34 generally finger-like and with shell 12 global formation.But, protuberance 34 can be any shape or thickness and shell 12 global formation, or other, as long as protuberance provides the surface that spiral case cut-off portion 28 can move along.Furthermore, it is possible to use vacuum source, power supply, source of the gas or drive driver 32 even with linkage.
In figure 3, being shown in broken lines the spiral case cut-off portion 28 being in primary importance, the air stream outlet 30 in this primary importance spiral case cut-off portion with the spiral case wall 14 at the upstream extremity place of gas channel and the downstream end at gas channel forms substantially continuous surface.The air gap (A) between primary importance, impeller and spiral case cut-off portion 28 is maximum for minimum range and air-flow 26 speed.
When hope reduces the speed of air-flow 26 from maximal rate and do not change the speed of motor 24/ impeller 20, it is energized to driver 32 and moves to the second position from primary importance so that the distance increased between impeller 20 and spiral case cut-off portion 28 i.e. the air gap (A) spiral case being ended portion 28.Can be the required speed between maximal rate (when when primary importance the air gap (A) is for minimum range) and minimum speed (when when second position the air gap (A) is for ultimate range) by the speed controlling of air-flow 26.
In figure 3, it is shown in broken lines spiral case cut-off portion 28 to be in primary importance and be shown in solid lines it and be in the second position.In this position, the end 38 of the contiguous protuberance 34 of the upstream extremity 36 in spiral case cut-off portion 28.In the present embodiment, as shown in action arrow B, spiral case cut-off portion 28 moves linearly between the first and second positions and the downstream 40 in spiral case cut-off portion moves along air stream outlet 30.
In another possible embodiment as shown in Figure 4, spiral case cut-off portion 28 includes upstream element 42 and downstream components 44, and they collectively form substantially continuous surface along gas channel with spiral case wall 14 and air stream outlet 30 in primary importance.In this embodiment, the second protuberance 46 extends from shell 12.
For dotted line 48, the downstream components 44 in spiral case cut-off portion can extend to the position of the end 50 of contiguous second protuberance 46.Alternatively, downstream components 44 can have the thickness similar with upstream element 42 and makes the length of the second protuberance 46 from the extension illustrated.Even more, downstream components the 44, second protuberance 46, shell 12 and air stream outlet 30 substantially can with any shape global formations, as long as surface 52 extends between the first and second positions, and surface 54 forms above-mentioned generally part continuous print surface.
In this embodiment, driver 32 makes upstream spiral case cut off member 42 move to the second position shown in solid to reduce the speed of air-flow along the first and second protuberances 34,46 from the primary importance shown in dotted line.First embodiment as noted, driver 32 can also make upstream spiral case cut off member 42 move to centre position, thus the air velocity adjusted between maximum and minima.
Upstream spiral case cut off member 42 is in primary importance and the air gap (A) obtains maximum air velocity when having minimum range.The second position at the end 38 of contiguous first protuberance 34 of upstream spiral case cut off member 42 obtains minimum air flow speed.In this second position, upstream spiral case cut off member 42 can also be close to the end 50 of the second protuberance 46.
In a still further aspect thereof, the method changing the air velocity in blower assy 10 comprises the following steps: uses the impeller 20 in the shell 12 with spiral case wall 14 to produce air-flow 26, form the air gap (A) and moved to the second position from primary importance by the protuberance 34 that makes spiral case cut-off portion extend along the position of the downstream 40 from the contiguous spiral case cut-off portion of spiral case wall adjust the air gap to affect air velocity between impeller and the spiral case cut-off portion 28 being in primary importance.
By driving impeller 20 to produce air-flow 26 with motor 24 to make impeller rotate and to produce air flowing in shell 12.Determined the speed of air-flow 26 by the air gap (A), the air gap (A) is for being in Fig. 3 by the distance between spiral case cut-off portion 28 and the impeller 20 of the primary importance shown in dotted line.By driving spiral case cut-off portion 28 so that spiral case cut-off portion move between the first position and the second position or the desired location that includes primary importance and the second position (being shown in solid lines in Fig. 2) form the air gap (A).Once it is determined that produce the desired location of required air velocity, it is possible to adjusting the air gap (A) affects air velocity.By make spiral case cut-off portion move between the first and second positions or the different position that includes the first and second positions adjust the air gap (A).
If formation the air gap, midpoint (A) between the first and second positions, then driver 32 will make spiral case cut-off portion move to will pass through towards the second position and expand the air gap (A) and reduce the speed of air-flow.On the contrary, driver 32 will make spiral case cut-off portion move to will pass through reduction the air gap (A) towards primary importance increases the speed of air-flow.
In a word, many interests have, due to offer, the blower assy utilizing driver adjustable spiral case cut-off portion, in order to can transmit required throughput in all operational modes of vehicle.This allows vehicle operators even at using blower assy in recirculation and heater mode.Up to now, the air velocity in these patterns is too high and cause can not by passenger compartment heating to temperature required.
