Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle air conditioner equipped with a pie level mode in which cold air is discharged from a ventilation outlet and warm air is discharged from a foot outlet.

[Prior Art] A vehicle air conditioner is equipped with a plurality of air outlets, such as a ventilator air outlet, a heater air outlet, and a differential [1-star air outlet], and the air conditioner is equipped with a plurality of air outlets, such as a ventilator air outlet, a heater air outlet, and a differential [1-star air outlet]. The air conditioner is provided so that the air conditioned in the air conditioner is blown out from the selected air outlet to each part of the vehicle interior.

The conventional air outlet switching mechanism that selects multiple air outlets has a plate-shaped damper arranged in the air path of each air outlet, and by rotating each damper, the air path is connected and disconnected. The outlet was selected according to the outlet switching mode.

However, when dampers are installed at multiple outlets, each damper requires wires and actuators to drive the damper, which not only complicates the control and mechanism, but also makes the damper difficult to operate before opening and closing. This has the problem that the damper cannot be operated smoothly with a uniform force because the damper is affected by the airflow when the damper is driven.

As a means of solving the above problems,
No. 1 51-40335 is known. This known technology discloses that a cylindrical structure having a plurality of air outlets, one end of which opens into the casing, and an opening around the periphery through which one or more of the air outlets can be opened, is installed in the mounting of an air conditioner that has a plurality of air outlets. By arranging a cylindrical damper and rotating the cylindrical damper in several ways, one cylindrical damper can control the opening and closing of a plurality of air outlets.

[Problems to be Solved by the Invention] If the instrument panel is shortened in the longitudinal direction, the space inside the vehicle will be expanded and the comfort inside the vehicle interior will be improved. , it is necessary to flatten the air conditioner installed inside it.

However, in the known technology, since the cylindrical damper has a cylindrical shape, when the air conditioner is flattened, the diameter of the cylindrical damper becomes smaller and the flow [t
becomes smaller. For this reason, there is a problem in that the amount of wind discharged into the vehicle interior is also reduced.

On the other hand, in a vehicle air conditioner, II1 passes through a heater.
The temperature of the air discharged from each outlet such as the ventilation outlet, heater outlet, etc. is determined by dividing ffi and the air volume that bypassed the heater by vA using an air mix damper or other means. is being adjusted.

The vehicle air conditioner of the above-mentioned known technology mixes and stirs the warm air heated by the heater and the cold air that has passed through the bypass passage in a cylindrical damper, and the temperature of the air discharged from each discharge port is were equalized.

In addition, in order to achieve cold feet, the vehicle air conditioner discharges cold air from the ventilator outlet,
A pie level mode is set in which hot air is discharged from the heater outlet.

However, in the vehicle air conditioner of the above-mentioned known technology, even when the pie level mode is set, the cold air and the hot air are mixed in the cylindrical damper, so that the ventilation air outlet and the heater outlet are mixed. Another problem was that the temperature difference became small.

The present invention has been made in view of the above circumstances, and its purpose is to control the opening and closing of a plurality of air outlets by operating one damper, simplify damper control and structure, and flatten the instrument panel. In addition to making efficient use of the space within the instrument panel to ensure a large amount of air discharged into the passenger compartment, when the pie level mode is set, the air that has passed through the heater is blown into the heater. To provide an air conditioner for a vehicle that can increase the temperature difference between a ventilator air outlet and a heater outlet by supplying air to an outlet.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a pentilage air outlet that generates an air flow toward the interior of a vehicle and blows the air flow toward at least the upper body of a vehicle occupant. , a ventilation duct equipped with a heater outlet that blows an air flow near the feet of a vehicle occupant, and an opening disposed within the ventilation duct that selectively opens one or more of the air outlets. a flexible membrane member; a membrane member moving means for moving the membrane member within the ventilation duct to open and close the plurality of air outlets; a heater provided in the ventilation duct, a bypass passage provided in the ventilation duct to bypass the heater, and an amount of air provided in the ventilation duct to be heated by the heater and to pass through the bypass passage. a temperature adjusting means for adjusting the ratio between the air flow rate and the air flow rate; a warm air inlet provided in the ventilation duct to guide the air flow that has passed through the heater into the air flow; A technical means is adopted consisting of an ffa duct equipped with a hot air outlet that can be discharged towards the blower outlet.

[Function] Since the damper used in the present invention is a flexible membrane member, one membrane member can be disposed opposite each outlet regardless of the shape of the ventilation duct, and The membrane member can be moved while facing the plurality of air outlets.

The movement of one membrane member causes one or more openings formed in the membrane member to move, and the location where the opening and the air outlet communicate with each other changes. , it is possible to control the opening and closing of a plurality of air outlets.

On the other hand, when the pie level mode is set, the membrane member is moved by the membrane member moving means so that the opening of the membrane member opens both the ventilation outlet and the heater outlet, and the temperature adjustment means to pass air through both the heater and the bypass passage.

As a result, part or all of the hot air that has passed through the heater flows into the Uffl duct, and the hot air is discharged from the outlet of the hot air duct toward the heater outlet. and,
The cold air that has passed through the bypass passage is discharged from the ventilation outlet.

[Effects of the Invention] According to the present invention, the switching mechanism and control of the air outlets can be simplified by opening a plurality of air outlets with a single flexible membrane member. Additionally, regardless of the shape of the ventilation duct, the membrane member can be disposed in the case facing the plurality of air outlets. For this reason, for example, even if the instrument panel is shortened in the longitudinal direction,
Make effective use of the space in the instrument panel,
Since the case can be flattened while ensuring a large amount of air m flowing into the air outlet, a large amount of air can be discharged from the air outlet into the vehicle interior.

Further, according to the present invention, when the pie level mode is set, the warm air that has passed through the heater is supplied to the heater outlet directly by the hot air duct, so that the temperature between the ventilation outlet and the heater outlet is The difference can be increased.

As a result, the hot air is mainly supplied to the third opening 30 and the defroster outlet 12, and a large amount of hot air is discharged to the lower surface of the windshield 15 via the defroster nozzle 16. on the other hand,
The hot air that did not flow into the driver 1jlo- 35 and the cold air that passed through the bypass passage 8 are mixed and agitated within the film damper 20, and are sent to the heater nozzle 19 via the first opening 28 and the heater outlet 14. The air is supplied to the vehicle occupants' feet and is discharged at a small volume.

As shown above, according to the present invention, when the pie level mode is set, the hot air that has passed through the heater is continuously supplied to the heater outlet by the hot air duct, so that the ventilation outlet It is possible to increase the temperature difference between the heater outlet and the heater outlet.
