Description

[Detailed explanation of the idea] (Industrial application field) TECHNICAL FIELD The present invention relates to an air conditioner for an automobile.

(Prior Art) An automobile air conditioning system includes a blower unit, an air conditioning unit such as a cooler or a heater, and a side ventilator disposed on the side of the driver's seat. The side ventilator has an inside/outside air switching means for switching between air intake and air outside the vehicle interior, and either of the air switched by the switching means is introduced and sent to the air conditioning unit, and the side ventilator is connected to the air conditioning unit. It has a vent switching means that communicates with the outside of the vehicle and switches between cutting off communication with the air conditioning unit (blocking air blowing from the air conditioning unit) and cutting off communication with the outside of the vehicle (blocking air blowing from outside the vehicle). It is conceivable that the internal/external air switching means of the blower unit has a switching lever provided near the driver's seat, and the vent switching means of the side ventilator has a switching lever (shutter lever) provided near the ventilator.

In this type of air conditioner, when operating the air conditioning unit, for example, a cooler unit, the blower unit is switched to the cabin air introduction side by the switching lever, and the side ventilator is switched to the cabin outside air cutoff side by the shutter lever. It is necessary to switch to . This is because when the air conditioning unit is in operation, it is undesirable for a large amount of fresh air from outside the vehicle to continue to flow in in order to improve air conditioning efficiency.

However, in the above type of air conditioner, it is troublesome to switch between the two levers, the blower unit switching lever and the side ventilator shutter lever, when the air conditioning unit is operated. Since the shutter lever is located near the side ventilator located on the side of the driver's seat, the driver must lean over to the side of the driver's seat to operate the shutter lever, which is cumbersome.

By the way, Japanese Utility Model Application Publication No. 59-78113 discloses a blower unit that is equipped with a blower unit having an inside/outside air switching door and an outside air introduction duct having an opening/closing door, and in which the inside/outside air switching door and the opening/closing door are completely interlocked, that is, the former A technique has been disclosed in which when the latter is switched to the inside air introduction side, the latter is closed (outside air introduction prohibited), and when the former is switched to the outside air introduction side, the latter is switched to open (outside air introduction allowed).

Therefore, it is conceivable to apply such a concept between the switching lever of the blower unit and the shutter lever of the side ventilator, but if it is simply applied as is, the shutter lever will be completely linked to the switching lever, and for example, The side ventilator needs to be able to introduce air from the air conditioning unit even when the blower unit is on the outside air introduction side, but a problem arises in that this becomes impossible.

Incidentally, Japanese Utility Model Application Publication No. 58-93510 discloses a side ventilator in which a shutter lever for blocking air from outside the vehicle is provided and the shutter lever is attached to the side ventilator itself.

(Purpose of the invention) In view of the above circumstances, the object of the present invention is to provide an air conditioner for an automobile comprising a blower unit having a switching lever as described above and a side ventilator having a shutter lever. An object of the present invention is to provide an air conditioner that simplifies lever operation and improves lever operability.

(Structure of the invention) In order to achieve the above-mentioned purpose, the air conditioner for an automobile according to the invention uses an inside/outside air switching door that switches between introducing air into the vehicle interior and air outside the vehicle, and a wire cable for switching between inside and outside air. A blower unit equipped with an inside/outside air switching means comprising a switching lever for switching and controlling an inside/outside air switching door; a shutter door for switching between shutting off air from an air conditioning unit and shutting off air from outside the vehicle; and a shutter lever for switching and controlling the shutter door. a side ventilator located on the side of the driver's seat and equipped with a vent switching means consisting of a side ventilator located on the side of the driver's seat; The inside/outside air switching means and the vent switching means are linked only when the switching means is switched to the air introduction side, so that the vent switching means is linked to the switching of the inside/outside air switching means to the cabin air introduction side. A linking means for switching to a side where air is cut off from the outside and allowing free operation of the vent switching means independent of the inside/outside air switching means when the inside/outside air switching means is on the air introduction side outside the vehicle interior, A wire cable for vent switching moved by the switching lever and the shutter lever are formed in an arc shape centered on a rotational fulcrum of the shutter lever and have a length within a rotational angle range of the shutter lever, and the vent switching wire cable is connected to the shutter lever. The end portion of the wire cable for use in the present invention is characterized in that the end portion of the wire cable is provided with a connecting means consisting of a slotted hole to which the end portion of the wire cable is slidably connected.

(Effect of the invention) Since the air conditioner according to the invention is equipped with the above-mentioned linking means, when operating an air conditioning unit such as a cooler, the switching lever of the blower unit can be switched to the cabin air introduction side. The linking means automatically switches the shutter lever of the side ventilator to the outside air cutoff side. Therefore, according to this air conditioner, when operating the air conditioning unit, the operator only needs to operate the switching lever of the blower unit, and the lever operation is only required once, and the driver previously had to lean over to operate the lever. Since there is no need to operate the shutter lever of the side ventilator, which was previously used, lever operation can be simplified and operability can be improved. Further, the linking means does not completely link the switching lever and the shutter lever, and when the switching lever is on the air introduction side outside the vehicle interior, the shutter lever can be freely operated independently of the switching lever. Therefore, even when the switching lever is located on the side where air is introduced outside the vehicle, the shutter lever can be positioned on the side where air is introduced from the air conditioning unit. Further, since the above-mentioned linking means is an extremely simple purely mechanical linking means consisting of a wire cable and a long hole as described above, it has the advantage that it can be manufactured at low cost, is easy to assemble, is not bulky, and has few failures.

The switching lever 12 is attached to an air conditioning control board 25, and the control board 25 is located approximately in the center of the instrument panel 8, that is, near the driver's seat, as shown in FIG. This switching lever 12 can be operated at any time. Further, 2d in the figure is a built-in part of the fan.

The side ventilator (the side ventilator shown in FIG. 2 is the ventilator located on the left side in FIG. 1) 6 has an exterior communication port 6a and
A shutter door 2 has an air conditioning unit communication port 6b and an air outlet 6c, and further closes either of the communication ports 6a, 6b to switch between blocking air from outside the vehicle compartment and blocking air from the air conditioning unit.
The vent switching means is comprised of a shutter lever 16 for controlling the switching of the shutter door 26. In the vent switching means, the shutter lever 16 is connected to the shutter door 26 via a connecting arm 28 which rotates about a shaft 28a.

The inside/outside air switching means and the vent switching means are linked by linking means 30. As shown,
This linking means 30 is connected to a vent switching wire cable 31 and a long hole 16 formed in the shutter lever 16.
a, one end of the wire cable 31 is connected to the first rotating arm 22 of the inside/outside air switching means, and connected to the switching lever 12 via the first rotating arm 22 and the inside/outside air switching wire cable 20. The other end is connected to the shutter lever 16.
It is slidably connected to the elongated hole 16a.

Note that when the switching lever 12 of the blower unit is on the outside air introduction side, the shutter lever 16 of the side ventilator can take two positions: the side that cuts off air from outside the cabin and the side that blocks air from the air conditioning unit. Of course, the shutter lever 16 is switched to the outside air blocking side by switching to the air introducing side only when the shutter lever 16 is located on the air blocking side from the air conditioning unit.

In the above embodiment, only the vent switching means of the left side ventilator is linked to the inside/outside air switching means of the blower unit by a linking means, but it is of course possible to link the vent switching means of the right side ventilator as well.

Since the air conditioner according to the present invention is equipped with the linking means configured as described above, when the switching lever of the blower unit is switched to the cabin air intake side, the side ventilator is automatically switched to the cabin outside air cutoff side. Therefore, the lever operation when operating the air conditioning unit is simplified, and when the blower unit is on the outside air introduction side, the side ventilator can freely introduce air from the air conditioning unit. Further, since the linking means is composed of the wire cable and the elongated hole as described above, the structure is simple.

The air conditioner according to the present invention can be modified in various ways within the scope of the gist of the present invention, and is not limited to the above embodiments.
