[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilating device for a vehicle cabin according to the preamble of the first aspect.

[0002]

2. Description of the Related Art In the case of known ventilators of this kind (US Pat.
062352), the air distribution device comprises two inlets for the first and second air guide ducts, an outlet for the air radiator in the foot space of the passenger compartment, an outlet for the air radiator in the center plane of the passenger compartment and a window. A cylindrical housing portion having a discharge port of a shield glass air radiator sequentially provided on a cylindrical wall, and a cylindrical outer shell rotatably received by the housing portion, closed at an end face, and rotatable along the inner wall of the housing portion. And a hollow cylindrical control mechanism. The cylindrical outer shell of the control mechanism has a housing portion associated with the inlet and the discharge port so that the air distribution of the five types of combinations of the two air guide ducts to the control mechanism connected to the discharge port is possible. An arranged opening is provided. In this case, one air guide duct guides cold air, another air guide guides warm air, so that the first air guide duct is provided with an evaporator of the air conditioner, The second air guide duct is provided with a heat exchanger through which the vehicle cooling water flows.

In the case of this known ventilator, the control mechanism 5
At each rotation position, air is emitted from each air radiator at any ratio, and radiated air is generated at each rotation position according to the ratio of the cross-sectional areas of the inlets of the cold air duct and the hot air duct opened. Determine exactly how the temperature will be controlled. On the contrary, it is not possible to distribute the air individually to the air radiators, that is, it is not possible to blow cold air, for example, via leg space nozzles.

[0004] Ventilation systems of this kind which are also known (DE 44)
47135A1) are on one side of the passenger compartment, ie,
It includes two mutually separate air distribution devices for providing air distribution to the driver and passenger sides. Each air distribution device includes a distribution housing having one cylindrical peripheral wall and two end walls. One end wall has an inlet,
The other end wall has a discharge port, and the peripheral wall has two discharge ports. A cylindrical valve sleeve having one peripheral wall and two end walls is rotatably received as a control mechanism in each distribution housing. An air outlet is provided on the valve sleeve end wall facing the distribution housing end wall provided with the air outlet, and two air outlets are provided on the valve sleeve peripheral wall. By rotating the valve sleeve in the valve housing, one or more of its air outlets can completely or partially overlap the outlet of the distribution housing, thus introducing the housing end wall from the air guide duct. Air supplied to the distribution housing via the port can flow to one or more outlets of the distribution housing connected to the air radiator if air flow is desired. The opening order depends on the arrangement of the mutually cooperating outlets of the distribution housing and the air outlet of the valve sleeve.

In this known ventilation system, the air can simply be distributed from the air guide duct to three types of air radiators. The mixing of the air in both air guide ducts is
Not performed based on the concept. Air conditioning of the air to be distributed is only possible by adjusting the cold and hot air by means of cold and hot air valves in front of both air guide ducts.

[0006] In the case of the same known ventilation device with two air flow paths (DE 35 14 358 C2), a control mechanism for selectively opening or closing both flow cross sections of the air guide path is provided in an open part and a closed part. It is configured as a hoisting blind including a belt that is divided and guided at a right angle to the air flow path and wound on a take-up roll provided on the side of the air flow path. The open and closed parts are configured on the belt according to a predetermined program. One air flow path
The other air flow path is configured as a cold air duct, and the other air flow path is configured as a hot air duct that branches off from the cold air duct and includes a heat exchanger and has a connection to the cold air duct before and after the heat exchanger. The hoisting blind covers the cross section of the cold air duct behind both connections and both connections as viewed in the direction of flow.

[0007]

The object of the invention is, on the one hand, to maintain, on the one hand, the possibility of mixing the air of both air supply ducts with a greater combination variety, and, on the other hand, to distribute the air to the air radiators. Of the type mentioned at the outset, with the possibility of distributing the conditioned air from at least two air supply ducts to the three planes of the cabin, and to simplify the control means for this purpose, The idea is to create a ventilation system.

[0008]

This object is achieved according to the invention by a ventilator of the type described in the preamble of claim 1 according to the invention.

In the ventilation device according to the present invention, the air radiators are distributed to two distribution housings connected to each other, and both air guide ducts are divided into the respective distribution housings, and are rotatably provided in the respective distribution housings. By controlling both the inlet, outlet and the connection between the distribution housing and the distribution housing by means of two control mechanisms, on the one hand, with respect to the mixing of the air supplied via both air guide ducts, on the other hand Has the advantage that greater combinatorial versatility is obtained with regard to the distribution of mixed or unmixed air to the air radiators on each plane of the cabin or on the planes of each other. This greater degree of freedom of combination-as in the other embodiments of the invention-allows one distribution housing to be provided with auxiliary inlets for the other distribution housing, thus air conditioning in three different ways. The possibility of mixing the air obtained is also obtained.

Based on the rotatable nature of the control mechanism in the distribution housing, as in the case of the known ventilators, a predetermined adjustment combination is implemented at each rotational position, a total of two to avoid the complicated control behavior of the air valve. A simple control method using a rotating member is possible.

In accordance with a preferred embodiment of the present invention, one air guide duct is supplied with fresh air from around the vehicle, for which purpose the duct is connected to a fresh air port and the other air guide duct is connected to the fresh air duct from the passenger compartment. The ventilation device according to the invention offers a particularly impressive advantage if it supplies circulating air and thus connects the duct to a circulating air port opening into the cabin (preferably the rear of the cabin) or the leg space. . It is advantageous if the other air guide duct is branched off from the first air guide duct and, like the air guide duct for the circulating air, is equipped with an air heater for selectively heating the air.

[0012] As practiced during prolonged driving in an environment loaded with harmful substances (eg city driving or traffic congestion) or to save on heating or cooling energy,
In the case of prolonged circulation of the circulating air with a small supply of fresh air, the humidity in the air inside the vehicle increases, and condensate forms on the glass. Separate air drying strategies that can prevent condensation are cumbersome, expensive, require extra space, and increase weight and energy consumption. By separately guiding the circulating air and the fresh air in both air guide ducts, the circulating air condition is maintained in which the humid circulating air is kept in the lower area of the vehicle and the fresh air which is almost moist is above the lower edge of the glass. Can be achieved in the vehicle. That is, dew condensation on the glass can be avoided. If it is desired to obtain the maximum air volume flow without regard to air quality, it is also possible to mix both types of air in both air guide ducts. If a large amount of air is required in the leg space or in the windshield, correspondingly, air can be supplemented from the fresh air duct to the leg space and circulating air can be supplemented in the windshield. The ventilation device according to the invention is also advantageous for vehicles with a hybrid or electric drive and a fuel-optimized internal combustion engine. All three types of drives generate little or no waste heat, so in the case of electric vehicles and hybrid engines in electric drive mode, all require supplemental heating. In this case, the ventilation device according to the present invention can circulate the circulating air at a high rate in order to minimize the energy used for supplementary heating. In the case of an internal combustion engine with an optimum fuel ratio, supplementary heating can be stopped or the required power can be minimized with a correspondingly high proportion of circulating air if the ventilation system according to the invention is used.

Further advantageous embodiments of the ventilation device according to the invention are disclosed in the dependent claims.

According to an advantageous embodiment of the invention, a pair of distribution housings with a discharge port, an inlet and a connection and an integral control mechanism, and an air guide duct connected to the inlet,
It is provided in duplicate, in this case, air radiators provided on the left and right sides of the passenger compartment or air radiators provided in the left front seat zone, right front seat zone and right rear seat zone of the passenger compartment,
Each is connected to the outlet of a pair of distribution housings. With the above configuration of the air distribution device, the ventilation control and the air temperature control can be separately performed on the left half and the right half of the passenger compartment, that is, on the driver side and the passenger side, and therefore, the operating device of the ventilation device Include separate adjustment schemes for the driver and passenger side. In this case, the adjustment of the control mechanism can be performed manually or electrically. In this case, motorized adjustment is preferred. This is because manual triggering of a total of four control mechanisms is complex and expensive.
Separate temperature selections for the passenger and driver sides of the cabin are realized by two separate heat exchangers in the case of a water-based control system, and by a corresponding air mixing in the case of an air-based control system. Is done.

If separate ventilation and temperature adjustments are required in the four seat zones of the passenger compartment, according to another embodiment of the invention, the outlet, the inlet, the connection and the integral control mechanism are provided. The air radiator provided in the front left seat zone, the right front seat zone, the left rear seat zone and the right rear seat zone of the passenger compartment is provided in quadruple with a distribution housing pair provided and an air guide duct connected to the inlet, respectively. Connect to the outlet of the distribution housing pair.

According to an advantageous embodiment of the invention, the control mechanism pair of each distribution housing pair can be adjusted independently of one another, but all the inlets of the distribution housing pair are connected to the outlet to the defrost nozzle. When one control mechanism pair is adjusted to the operating mode "defrost level", the other control mechanism is likewise forced to adjust to the "defrost level". In this mode of operation of the control mechanism pairs, it is advantageous if the inlets of all distribution housing pairs are supplemented with hot air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments.

The ventilator of the vehicle cabin, shown as a partial longitudinal section in FIG. 1, in combination with a blower system and a heating or air conditioning system, can be cooled to a lower temperature on each plane of the cabin according to the needs of the occupants. Helps supply air that is conditioned at a higher temperature or other conditions. For this purpose, an air radiator (not shown) is provided as a defrosting nozzle on the lower edge of the windshield or windshield glass on the upper plane of the passenger compartment, and in the leg space on the lower plane of the passenger compartment. It is provided as a leg space nozzle. In this case, the air distribution device 10 of the ventilator selects differently conditioned air supplied from two or three separate air guide ducts 11, 12, 13 to the air radiator of each plane or a predetermined combination plane. Distribute it. In the embodiment shown in FIG. 1, the first air guide duct 11 receives a supply of fresh air and is thus connected to the fresh air inlet of the vehicle and the second air guide duct 12
Receives a selective supply of circulating air or fresh air withdrawn from the cabin, and is thus connected to a circulating air port and a fresh air port provided in the cabin (preferably the leg space or the rear of the cabin), In this case, both openings can be selectively blocked by the valve mechanism. The third air guide duct 13 is
It branches off from the air guide duct 11 and thus also guides fresh air. The upper part 141 of the heat exchanger 14, which flows through the vehicle cooling water and serves to heat the flowing air, passes through the third air guide duct 13, and the lower part 142 passes through the second air guide duct 12. When a ventilation device is used in combination with an air conditioner, as shown by a broken line in FIG. The upper part 361 is installed in the third air guide duct 13, and the lower part 362 is installed in the second air guide duct 12. In this case, the third air guide duct 13 is connected to the first air guide duct 11 in front of the evaporator 36.
Branches from.

The air distribution device 10 includes an air guide duct 11
It has dispensing housings 15, 16 connected to -13 and two control mechanisms 17, 18 coaxially arranged and rotatably received in each of the dispensing housings 15, 16 respectively. The distribution housings 15 and 16 are formed in a cylindrical shape, and the control mechanisms 17 and 18 respectively include drums 19 and 20 rotatably supported by the respective distribution housings 15 and 16.
The drum shell, for example made of film, rotates along the inner surface of the cylindrical dispensing housings 15; 16 with a radial play which ensures a rotational movement.

In the installation position of the ventilation device, both distribution housings 15, 16 overlap vertically, in which case the housing axes extend parallel to one another. The upper first distribution housing 15 includes two discharge ports 21 and 22 distributed on the peripheral surface, a connection port 23, and two introduction ports 24 and 24.
25. The lower second distribution housing 16 includes a discharge port 26, a connection port 27,
And an inlet 28. Both distribution housings 15,1
6, the outlets 21, 22, 26 communicate with the air radiators on three planes of the passenger compartment, that is, the outlet 21 of the first distribution housing 15 communicates with the defrost nozzle, and the first distribution housing 15 Outlet 22 communicates with the center nozzle, and the outlet 26 of the second distribution housing 16 communicates with the leg space nozzle. The two connection ports 23, 27 of the two distribution housings 15, 16 are mutually connected via a connection duct 29. The inlet 24 of the first distribution housing 15 forms the mouth of the first air guide duct 11, the inlet 25 of the first distribution housing 15 forms the mouth of the third air guide duct 13, and the second The inlet 28 of the distribution housing 16 is
The mouth of the second air guide duct 12 is formed. In FIG. 1, the air flow path leading to the air radiator (not shown) is indicated by DEF for the defrosting nozzle, MITTE for the center nozzle, and FUSS for the leg space nozzle for clarity. The cylindrical walls of the drums 19, 20 are provided with openings 30; 31 which have an axial length corresponding to the length of the openings 21-28 of the distribution housings 15, 16 and are arranged circumferentially one after the other. In this case, the first drum 19 has a total of four openings 30 and the second drum 20
Has a total of three openings 31. Each opening 30, 31
Are configured to have different widths in the circumferential direction of the drums 19 and 20. In this case, the widths and distributions of the openings 30 and 31 are different from each other in the distribution housings 15 and 16 at a predetermined rotation position of the drums 19 and 20. It depends on 24-28 desired triggers. The rotation of each of the drums 19, 20 is adjusted manually or by an electric operating device, in which case each of the drums 19, 20 can be adjusted separately. Both drums 19, 20 are such that the rotational adjustment of the drum 20 is derived from or synchronized with the rotational adjustment of the drum 19.
Can be forcibly linked. Depending on the rotational position of the two drums 19, 20, the control surfaces for opening and closing the openings 21-28 of the two distribution housings 15, 16 are formed by the two cylindrical drum shells, the air guide ducts 11-13 are individually In addition, the three air streams supplied to the air distribution device 10 are mixed in different ratios and have different discharges, wholly or partially connected, in whole or in part, to each opening 21-28 or opening combination. An airflow combination occurs and flows into the cabin.

FIGS. 1 to 5 show an example of the air distribution system 5.
Different modes are shown. When the rotations of both drums 19 and 20 are adjusted as shown in FIG. 1, a so-called FACE mode occurs. In this case, without regard to air quality, the maximum air volume flow is blown into the passenger compartment via the central nozzle, in which case all three air guide ducts 11-13 are connected to the outlet 22 of the central nozzle. Connected. Three inlets 24,
The drums 19 and 20 are adjusted so that the connection ports 25 and 28, both the connection ports 23 and 27 and the discharge port 22 of the center nozzle are opened, and the discharge ports 21 and 26 to the defrosting nozzle and the leg space nozzle are closed. You. The air flow generated during the rotation adjustment of the drums 19 and 20 is schematically shown by arrows in FIG. The circulating air leaving the air guide duct 12 or, if desired, the fresh air and the fresh air leaving the air guide duct 13 are possibly heated. Fresh air leaving the air guide duct 13 is at ambient temperature.

When the rotation of both drums 19 and 20 shown in FIG. 2 is adjusted, the apparatus is operated in a so-called BI-LEVEL mode. In this case, independent air guidance is possible by blocking the connection ports 23, 27. In this case, the circulating air is sucked from the cabin via the second air guide duct 12, possibly heated, and blown again into the leg space of the vehicle cabin via the leg space nozzle, while the heating air The fresh air thus collected flows into the upper part of the passenger compartment through the central nozzle. In this case, an air layer is formed in the passenger compartment,
That is, moist warm circulating air is retained in the lower vehicle range, and cooler fresh air that is not moist stagnates above the lower edge of the windshield glass.

When the drums 19 and 20 are adjusted as shown in FIG. 4, that is, at the so-called FOOT / DEFROST level, a similar air layer can be obtained. In this case, FIG.
In contrast to the regulated state, heated fresh air is blown against the windshield and the side glass, thus being blown into the upper area of the passenger compartment, i.e. to suppress the condensation of the glass and to perform defrosting.

FIG. 3 shows the FOO of both drums 19 and 20.
An adjustment mode called T-level is shown. This adjustment
This is done when a lot of air is needed in the leg space. In this case, in addition to the possibly heated circulating air, heated or unheated fresh air can be transferred from the third air guide duct 13 via the connection ports 23, 27 of the two distribution housings 15, 16 to the legs. Sent to space. The discharge ports 21 and 22 to the defrosting nozzle and the center nozzle are blocked.

FIG. 5 shows the state of adjustment of both drums 19 and 20 in the mode "DEFOST level". This adjustment is necessary, for example, when a large amount of airflow is required for the windshield glass of the vehicle interior. In this case, depending on the activation of the heat exchanger, the second air guide duct 1
From 2, low-temperature or heated circulating air is blown into the defrost nozzle, and low-temperature or heated fresh air is blown from the third air guide duct 13 into the defrost nozzle. The outlets 22, 26 to the center nozzle and leg space nozzle are blocked. If the vehicle engine supplies sufficient waste heat, it is preferable to supply fresh air instead of circulating air to the second air guide duct to ensure that condensation of the glass is avoided.

The ventilating device shown in FIG. 6 as a partial longitudinal section shows that the two control mechanisms 17, 18 rotatably received in the two distribution housings 15, 16 are not two drums but one distribution housing. 15 to another dispensing housing 16 and dispensing housing 1
It differs from the above described ventilators in that it consists of endless belts guided along 5, 16 cylindrical inner walls. The guide element is, for example, provided for both distribution housings 15,
It can be realized by two hollow rolls 33, 34 arranged coaxially in 16 and having the roll shell arranged in a grid so that the air flow passing through the roll shell is essentially unaffected. In this case, as in the case of the drums 19, 20 in FIG. 1, an endless belt 32 provided with openings 30, 31 provides a circulation control surface which alternately opens and closes the openings 21-28 of both distribution housings 15, 16. To form In this case, for example, based on a predetermined program corresponding to the continuous rotation positions of the control mechanisms 17 and 18 in FIG. 1-5, the introduction ports 24 and 25 of the distribution housings 15 and 16 correspond to the corresponding discharge ports 21, 22 and 26. The arrangement and configuration of the openings 30 and 31 are determined so as to be connected to the connection ports 23 and 27.
The endless belt 32 is fed by both hollow rolls 3.
Guaranteed by friction or form connection with 3,34.
In this case, one of the two hollow rolls 33, 34 is rotated manually or by a power operating device. The pressing roll 35 gently pushes the opposing endless belt so that the two distributing housings 15, 16 are airtightly separated from each other even when the connection port is closed. To the mouth of the second air guide duct 12.

In the case of the air distribution device shown in FIGS. 1 to 5 in which the control mechanisms 17 and 18 are configured as drums 19 and 20, for example, supplementary discharge ports connected to an air radiator additionally provided at the bottom of the vehicle compartment are provided for both of them. It can also be provided on the end faces of the distribution housings 15,16. In this case, the drums 19, 2 with closed end faces
The 0 end face is provided with a supplemental opening which, in a given rotational position, coincides with the associated outlet of the end wall of the distribution housing 15,16. With the proper arrangement of the openings 30, 31 on the drums 19, 20, any mode combination can be "programmed".

The ventilator shown in partial sectional views in FIGS. 7 and 8 wants to separately perform ventilation control and temperature control on the left and right halves of the passenger compartment, ie, on the driver side and the passenger side. If used. In this case, the discharge port, the introduction port, the connection port 27, and the integrated control mechanism 17, 1
