DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed air conditioner installed behind a driver seat and a passenger seat in a truck.

[0002]

2. Description of the Related Art In a truck, since a driver seat and a passenger seat are separated from a bed provided behind the seat by a curtain, conventionally, when the curtain is closed, air conditioning for the driver seat and the passenger seat is performed. There was a problem that it was difficult to sufficiently air-condition the bed with the device.

[0003] When air conditioning on the bed is performed by extending a duct from the air conditioner to the bed at the rear, as shown in FIG. The face duct 2 and the foot duct 3 to the passenger seat are branched, and air blows out from the face duct 2 as shown by an arrow during face air conditioning, and air blows out from the foot duct 3 as shown by an arrow during foot air conditioning. Since this selection is determined by a seated person, in order to always perform air conditioning on the rear bed 4, the first duct 5 branched from the face duct 2 and extended onto the bed 4 and the foot duct 3 A second duct 6 that branches off and extends onto the bed 4, respectively.
It was necessary to blow air from the rear opening of each duct as shown by the arrows. Reference numeral 7 denotes a curtain that separates the driver's seat and the passenger's seat from the bed 4.

However, in this case, it is impossible for a person on the bed 4 to know at all from which opening of the first duct 5 or the second duct 6 the air is blown out onto the bed 4. When the curtain 7 is closed, the usability on the bed 4 becomes poor, and arranging as many as two ducts 5, 6 from the air conditioning unit 1 on the bed 4 at the rear makes the floor console in the cab impossible. Was not always easy due to the presence of

SUMMARY OF THE INVENTION It is an object of the present invention to make it possible to always perform air conditioning on a bed installed behind a driver's seat and a passenger's seat in a truck with a simple structure. It is in.

[0006]

Therefore, a truck bed air conditioner according to the present invention comprises a face duct and a foot duct extending from an air conditioning unit mounted on a truck to a driver's seat and / or a passenger seat, and the face duct. have a bed ducts extending one from a foot duct into the bed of the back is connected to branch respectively, the monoglyceride

During air conditioning, air blows out from the foot duct into the vehicle interior
On the other hand, the air pressure causes bed duct
Between the junction to the bed and the connection point of the bed duct
The check valve is opened and air flows into the bed duct ,
The air-conditioning air at that time is also guided to the bed behind,
Ru can be always satisfactorily perform air conditioning on just as bed and in front of the driver's seat and or the passenger seat. Moreover, the face
Bed duct is separated from duct and foot duct.
The presence of each check valve despite being connected in a fork
Air flow to the foot duct during face air conditioning
Air flow during foot air conditioning.
Driver's seat and / or
Prevents deterioration of air conditioning feeling for passengers on the front passenger seat

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described by assigning the same reference numerals to the same parts as those of the conventional apparatus. In FIG. 1, a curtain 7 separates a driver's seat and a passenger seat of a truck from a bed 4 provided behind the truck, and a face duct 2 from the air conditioning unit 1 to the driver's seat and the passenger seat.
And the foot duct 3 are branched from each other, and the bed duct 10 branched from each of the face duct 2 and the foot duct 3 and connected to the rear extends in the cab, passes under the curtain 7 and passes on the bed 4. Opening 11.

As shown in FIGS. 2 and 3, a square frame 12 is fixed to the opening 11, and an upper end of a soft flexible rubber plate 13 is attached to the square frame 12, and the weight is reduced by its own weight. While the hanging rubber plate 13 closes the opening 11, non-return valves 14 and 15 are provided at portions where the face duct 2 and the foot duct 3 branch off to the bed duct 10, respectively. Air is allowed to flow from each of the foot ducts 3 into the bed duct 10, but the backflow is prevented.

In the above-described apparatus, when air is blown from the face duct 2 into the passenger compartment by the operation of the air conditioning unit 1 for the face air conditioning of the driver seat and / or the passenger seat as shown by an arrow in FIG. As a result, the check valve 14 is opened and air flows into the bed duct 10,
The check valve 15 is closed by the air pressure in the bed duct 10, and the rubber plate 13 closing the opening 11 is pushed open as shown by a two-dot chain line in FIGS. Since air flows out of the opening 11 onto the bed 4 as shown by the arrow in FIG. 1, air can be satisfactorily applied to the bed 4 as well as the driver's seat and / or the passenger's seat.

Further, when air is blown from the foot duct 3 into the vehicle compartment by the operation of the air conditioning unit 1 as shown by an arrow in FIG. When the stop valve 15 is opened, air flows into the bed duct 10 and the bed duct 10
The check valve 14 is closed by the air pressure in the inside, and the rubber plate 13 closing the opening 11 is pushed open as shown by a two-dot chain line in FIGS. Part 1
As it flows out from 1 onto the bed 4 as shown by the arrow in FIG.
Again, air conditioning can be satisfactorily applied to the bed 4 as well as the driver's seat and / or the passenger seat.

Therefore, comfortable air conditioning can always be performed on the bed 4 in the same manner as the driver's seat and / or the passenger seat.
In addition, since the outflow of the air onto the bed 4 is determined at a predetermined position of the opening 11, the usability of the bed 4 is significantly improved as compared with the conventional case, and the bed 4 becomes more convenient. Further, since the bed duct 10 extending rearward from the connection point near the air conditioning unit 1 is a single one, there is an advantage that the structure is simple and the piping thereof can be performed relatively easily.

Further, at the time of face air conditioning, the check valve 15 is closed via the bed duct 10 by the air pressure in the face duct 2 and at the time of foot air conditioning, the check is performed via the bed duct 10 by the air pressure within the foot duct 3. Since the valve 14 is closed to reliably prevent air from flowing between the face duct 2 and the foot duct 3, it is easy for the installation of the bed duct 10 to deteriorate the air conditioning feeling of the driver's seat and / or the passenger seat. Can be suppressed.

In the above embodiment, the opening of the bed duct with respect to the bed is automatically opened / closed in accordance with the presence or absence of air pressure in the bed duct. Mounting, allowing the person on the bed to open and close freely, or installing a steering louver normally provided at the outlet of the face duct at the opening of the bed duct to the bed, and air conditioning on each bed Needless to say, it can be further adjusted to your liking, and since there is only one bed duct extending to the bed behind, the opening for the bed is placed above the bed, for example, on the ceiling There is an advantage that the operation can be performed relatively easily.

[0015]

In the truck bed air conditioner according to the present invention, regardless of whether the face duct or the foot duct is used at the time of operation of the air conditioning unit, the bed duct branched from and connected to each of the ducts. since the air-conditioning air when the well to the rear of the bed is led, it can be performed constantly satisfactorily conditioned on the bed just like the front of a driver's seat and or the passenger seat, moreover, phosphate
From the duct and foot duct
The driver's seat and / or
Confirmed that the air conditioning feeling for passengers on the passenger seat had deteriorated.
There is an advantage that can be really prevented.
