Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to an interior of a motor vehicle, in particular a passenger car, which is provided with an air outlet for conveying air to the foot area and head area of the occupant and to the glass area of the vehicle. The present invention relates to a heating device and/or a cooling device, and more specifically, relates to a heating device and/or a cooling device in which the air temperature in the foot area and the glass area can be adjusted to a low value separately from the air temperature in the head area. It is something.

In devices of this type, which are described in DE 32 32 957 A1 and EP 102 611, the arrangement of the operating element for adjusting the air temperature for the head area is not taken into account.

In the Jaguar XJ-HE, temperature regulation of the air outlet for the head area and the glass area is carried out in common by means of a regulating wheel which is arranged below the radio operating element in the cooling system and in the radio system. In this case, it is impossible to independently adjust the temperature of the head region, and even if a temperature control element is attached to the air outlet for one head region, it will be placed in a position that is difficult for the occupant to see.

Furthermore, for example German Patent Publication No. 2153743 and DE-Zmot, Volume 4 1986°12.2.86

1985. As described on pages 41 to 59, in ordinary passenger cars it is customary to attach operating elements for air volume and air flow direction directly to the air outlet for the head area. . In this case, no air temperature regulation device is provided, so that only the outside air can be regulated for the head area, or the warm air associated with the temperature regulation of the air for the foot area and/or the glass area can be regulated. Adjustable.

An object of the present invention is to provide the possibility of operation to the air outflow section for the head area, to make all air conditioning adjustments including air temperature adjustment easy for the occupants, and to provide comfort. To provide a heating device and/or a cooling device that is effective both in terms of performance and in terms of reducing driver's annoyance.

Structure and Effects In order to achieve the above object, the present invention has an air outlet for sending air to the head area, and/or an air outlet that is located inside the air outlet.
or an operating element provided in the edge region of the opening of the air outlet, each operating element.

It is characterized by determining the direction, amount, and temperature of the outflowing air.

The patent claims 2 to 5 indicate advantageous embodiments of the invention. Operation is facilitated even for beginners by integrating the operating element for optionally adjusting the temperature of the air stream to the head area into an operating element that is normally attached directly to the air outlet.

Furthermore, the configuration according to the invention is advantageous both in terms of safety in the event of a collision and in terms of shape. This especially applies to claim 4.
The operating element resulting from the configuration described in paragraph 1 and provided according to claim 4 can be embedded without protruding into the instrument panel and can be adapted to the overall shape of the air outlet.

lost garden tribe Next, embodiments of the present invention will be described using the accompanying drawings.

The operating unit 1 of the automotive air conditioning system 2 equipped with the air conditioner 3 has a manually operable selection device for determining the temperature 1 intensity and distribution of the cold air flow and/or the warm air flow. The outlets of the cold air flow and warm air flow are the windshield de-icing section 4 and the side window de-icing section 5. Driver side footwell heating section and rear seat heating section 6. Passenger side footwell heating section and rear seat heating section7.
It consists of a driver side ventilation section 8, a passenger seat side ventilation section 9, and a rear seat ventilation section 10.

To ensure this functionality, the air conditioner 3 has the usual components, namely a multi-part casing 11, an air blower 121, an evaporator 13 connected to a refrigerant circuit (not shown), A heat exchanger 14 connected to the internal combustion engine refrigerant circuit (not shown), an air duct 15.1 with an air outlet and a control valve, a servo motor 16 operated internally or by air pressure, etc., an outdoor temperature sensor 17 and a vehicle interior temperature sensor 18 and a refrigerant temperature sensor 19. It has a temperature adjustment value setter and an electric switch connected to a key on the operating section l.

Similarly, an electrical and electronic controller 20 is disposed on the operating section 1 or at a convenient location in the vehicle for maintenance.

This controller 20 correlates signal values sent from various generators, sensors, and switches and sends adjustment signals to the servo motor 16 according to a program. Servo motor 1
6 adjusts each adjustment engine so that the driver side and the passenger seat side are in the same state or in different states.

As described above, the heating and cooling system according to the present invention allows heating and cooling to be tailored to the needs of the driver and passenger, even if they have completely different needs regarding temperature and ventilation. The driver side ventilation section 8 and the passenger seat side ventilation section 9, which can be adjusted to fit the head area of the occupant, can adjust the flow direction of air, the amount of air, and the temperature of the air. As can be seen from FIG. 3, an operation button 22 for adjusting the direction of air radiation in the horizontal and vertical directions is arranged between the driver side ventilation section 8 and the passenger seat side ventilation section 9. Immediately next to the side ventilation section 8 and the passenger seat side ventilation section 9, an operating wheel 23 that can be adjusted in the vertical direction is arranged to adjust the amount of air.

In order to select the temperature of the air, a vertically adjustable control wheel 24 is provided. The operating wheel 24 is common to the driver side ventilation section 8 and the passenger seat side ventilation section 9, and is arranged between the two. The operating wheels 23 and 24 are provided with symbols 25 and 26 representing upward and downward adjustment movements associated with increasing and decreasing the air volume or air temperature.

When the operating wheel 24 is adjusted, the opening angle of the mixing valve 27 changes to ia'! via a mechanical, pneumatic and/or electrical remote control unit (not shown). 1 will be given.

In the air conditioner/heater 3 of FIG. 2, the mixing valve 27 appropriately opens the fresh air/cold air opening on the one hand and the warm air opening on the other hand.
