The specific embodiment
[34] figure 1 illustrates the perspective diagram of first kind of embodiment of automobile seat drafting apparatus 2 according to the invention.
[35] described device comprises a casing 4, is furnished with an air by-pass passage 6 and a seat air by-pass passage 8 in described casing.By a seat air duct 10, seat air by-pass passage 8 is communicated with seat 12.Described pipeline 10 can be deformable, and is for example telescopic or flexible, changes with respect to the position of drafting apparatus 2 to allow seat 12, particularly when wishing to regulate height of seat.One propelling unit 14 is arranged in the inside of casing 4.When propelling unit rotated according to the hand of rotation shown in the arrow 18, described propelling unit can pass through air by-pass passage 6 aspirated airs, meaning just as shown in arrow 16.The air air by-pass passage 8 that passes as shown in arrow 20 is blown into a bag 22 that is arranged in the seat base always.The obturation of seat be porose or have finely porous, thereby allow air direction as shown in arrow 23 to pass.
[36] seat 12 can also have a bag 24, and described bag is arranged in the back of seat, and is connected to bag 22 by pipeline (not illustrating in the drawings), and described pipeline allows air to pass through.The obturation of backrest also is allow that air passes porose or has finely porous.
[37] better, a dust filter 26 is placed on the entrance of seat air by-pass passage 6, is used for adsorbing the dust that is suspended in institute's aspirated air.Heating arrangement is resistance for example, and particularly positive temperature coefficient resistor (CTP) is placed on after the air filter.Resistance can heat the air of delivering to bag 22 and bag 24.
[38] hand of rotation of propelling unit 14 can reverse, thus the direction rotation that described propelling unit is illustrated according to arrow 30.Under described situation, not by air by-pass passage 6 aspirated airs, and passing the backrest and the base of seat 12 shown in the arrow 32 that dotted line is represented, air is inhaled into.Pass that air that the seat obturation is inhaled into is as shown in arrow 34 to be entered in the casing by seat air duct 10, follow the outside that is discharged to casing as shown in arrow 36.Ventilated seating device 2 among Fig. 1 can be according to different pattern work.In summer, air can be passed the seat obturation and aspirate out, so that with its cooling.Otherwise, can be with air inspiration self-propelled vehicle indoor and it is passed obturation blow.On the contrary, when hope was heated seat again, such as in the winter time, device can be only to blow pattern work.Air is as shown in arrow 1 to be inhaled into, and then before in base that is transported to seat 12 and the backrest, is heated through resistance 28.
[39] resistance CTP 28 can be with the work of standard-sized sheet or complete shut-down pattern, and perhaps in a more perfect embodiment, described resistance can classification, so that according to its formula power not at the same level of adjustment of hope.Can see in addition: described device moves in the mode that is totally independent of self-propelled vehicle ventilation, heating and/or conditioning unit.Even self-propelled vehicle is not equipped with an air conditioner loop in addition, described resistance also can be worked.
[40] as a modification, can described device is perfect in addition, so that have a working stage that is called " removal greenhouse ".Removing the greenhouse helps getting rid of to be collected in the seat 12 adding hot air.
[41] for this reason, as what can see in Figure 10, seat 12 disposes a discharge-channel 200, and described discharge-channel is communicated to 22 li of bags on the one hand and other direction leads to the outside of seat 12.Bag 22 and seat 12 outsides are connected is subjected to a vent valves 202 controls, and described vent valves opens or closes discharge-channel 200.According to embodiment, remove the necessary air in greenhouse in order to provide, also at casing 4 li configurations, one free air diffuser 204 and an air intake valve 206.
[42] remove the greenhouse by opening air intake valve 206 and vent valves 202 is implemented.Propelling unit 14 thereby air 208 is flowed.Air 208 enters 22 li of bags, therefore forms a circulation, and described circulation makes the hot air 210 that adds in the bag 22 that accumulated in seat 12 originally discharge by discharge-channel 200.Therefore before aforementioned means work, can give off a certain amount of heat that accumulates in the seat 12.Air 208 can be the air that obtains in heating arrangement 28 downstreams or the recirculated air that obtains below seat or the air that obtains in heating arrangement 28 upstreams.
[43] when the device normal operation, vent valves 202 and air intake valve 206 boths close.Therefore, described device can avoid supplying with one air of passenger when starting, and the temperature of described air is increased significantly owing to remain on the heat in the seat.
[44] as a kind of modification, have only discharge-channel 200 to be used, and free air diffuser 204 is made of air by-pass passage 6, remove the greenhouse and before using heating arrangement 28, implement.
[45] in the example described here, remove the greenhouse bag 22 is implemented, but also can implement or be implemented on simultaneously described two bags as required bag 24.
[46] vertical sectional view and a horizontal sectional plane of second kind of embodiment of drafting apparatus according to the invention are shown among Fig. 2 and Fig. 3 respectively.It is different from the above-mentioned embodiment part shown in Fig. 1 and is that described drafting apparatus comprises that one is parallel to second air by-pass passage 46 of first air by-pass passage 6.Opposite with passage 6, passage 46 does not have heating resistor.On the contrary, described second air by-pass passage, 46 possible configurations have a dust filter.As shown in Figure 2, can complete closed first air by-pass passage 6 or second air by-pass passage 46 around one 50 pivotally attached one mixing valve 48.When second channel during by complete closed, air flows by first air by-pass passage fully, and on the contrary, and when first passage during by complete closed, air flows by second air by-pass passage fully.In addition, mixing valve 48 can be in all midways location between the aforesaid end position, thereby crosses the air of first and second air by-pass passages by the variable ratio mixed flow.Therefore, by mixing with required ratio by air resistance 28 (passage 6) heating or heat, can regulate the temperature that is blown into the interior air of seat with the air under the ambient temperature--it is sucked in the self-propelled vehicle chamber through second channel 46.Drafting apparatus is equipped with an electrical motor 50, and the axle of described electrical motor is placed vertically.Described direct motor drive one is placed on the impeller 52 in the volute 54, and described impeller can blow air by seat air by-pass passage 8, and described seat air by-pass passage connects one or more automobile seats 12 by a unshowned seat air duct.In said embodiment, opposite with last embodiment, the hand of rotation of propelling unit 52 can not be converse.Therefore, described device is by blowing the cool air of passing the seat obturation and with the work of ventilated seating pattern, resistance 28 thereby be disconnected, perhaps described resistance can be by heating mode work, and the hot air that resistance 28 produces can mix mutually according to the lower air of variable ratio and the temperature that is entered by second free air diffuser 46.
[47] at the third embodiment of ventilated seating device according to the invention shown in Fig. 4 and Fig. 5.The same with the embodiment of Fig. 2 and Fig. 3, described device comprises one first air by-pass passage 6, is furnished with a dust filter 26 and positive temperature coefficient resistor 28 in described first air by-pass passage; And one second air by-pass passage 46, as described above, one can mix air-flow from first and second air by-pass passages according to variable ratio around its 50 pivotally attached mixing valve 48.
[48] in described the third embodiment, propelling unit 14 is placed in the pipeline, and described pipeline has one first open end 60 and one second open end 62.Arrange facing to first open end 60 around a S. A. 66 pivotallys attached one first valve 64, and arrange facing to second open end 62 of pipeline 58 around a S. A. 70 pivotallys attached one second valve 68.Valve 64 can be arranged in the primary importance shown in Fig. 4 solid line, and on described position, described valve makes the open end 60 of pipeline 58 be connected with the outside of casing 4, particularly second air by-pass passage 46 by being opened by mixing valve 48.Valve 64 can be arranged in the second place that Fig. 4 is shown in dotted line equally, on described position, first open end of pipeline 58 is connected with the air by-pass passage 8 of seat, therefore and, be connected with bag 22 and bag 24 in base that is arranged in one or more seats 12 and the backrest by seat air duct 10.Similarly, second valve 68 can be in Fig. 4 with movable between the position shown in the solid line and the second place that in Fig. 4, is shown in broken lines: on the described position shown in the solid line, second open end 62 of pipeline 58 is connected with seat air by-pass passage 8, and these are shown in arrow 74 and 76; On the described second place, second open end 62 of pipeline 58 is connected with the outside of casing, particularly by second air by-pass passage 46.It should be noted that valve 64 and 68 can not be in the midway location between foregoing two positions.
[49] on the position shown in Fig. 4, air passes the seat obturation by propelling unit 14 and is sucked out shown in arrow 74 and 76, and shown in arrow 72, is discharged to the outside of drafting apparatus through passage 46.On the contrary, on the position shown in Fig. 5, air by air by-pass passage 46, is inhaled into the self-propelled vehicle chamber, and is blown into shown in arrow 80 in the obturation of seat 12 shown in arrow 78.Therefore, because the effect of first and second valves 64,68 can make the direction of air-flow converse, keep the identical hand of rotation of propelling unit 14 simultaneously.Under described mode, drafting apparatus can or blow mode operation with suction mode.When it is worked with suction mode, obviously can't heat the air that is discharged in the operator's compartment.This is because first air by-pass passage 6 is at off position.Positive temperature coefficient resistor CTP 28 stops using.On the contrary, blowing on the position, drafting apparatus can be with two kinds of different pattern work.Mixing valve 48 can be in the off position of representing with solid line among Fig. 5, thereby cool air is blown in the seat of self-propelled vehicle as far as possible.This promptly is the described operational mode that can use summer.
[50] as a kind of modification, as shown in Figure 11, utilize discharge-channel 200, removal greenhouse passage 204, vent valves 202 and remove their such operations as shown in Figure 10 of greenhouse valve 206--, can make described device have one and remove the greenhouse function.In an other modification, have only discharge-channel 200 to be used, and free air diffuser 204 is made of the enforcement before use heating arrangement 28 of removal greenhouse the air by-pass passage 6 or second air by-pass passage 46.
