The structure of the regenerative cooling system shown in FIG. 6 is based on an air outlet duct 1 having an air outlet 16 through which cool air is blown.
Reference numeral 2 denotes a bed storage type cold storage unit installed on the nap bed 2. In this structure, in order to prevent cold air from directly hitting a person on the nap bed 2, the outlet duct 1 is set so that the outlet 16 is at a predetermined height.
2 are formed. For this reason, there is a problem that the upper portion of the blow duct 12 not only obstructs the view from the side window 56 but also occupies a large space.

[0004]

As described above, when the conventional regenerative cooling device is mounted, the visibility from the rear window and the side window is obstructed, so that the visibility during driving the vehicle is poor. And safety issues arise. In addition, the outlet duct of the bed-bed cold storage unit as described above occupies a large space such as a nap room where the cold storage unit is installed, so that a space that can be used effectively is lost.

Accordingly, an object of the present invention is to provide a regenerative unit that improves visibility and saves space.

[0006]

To achieve the above object, the present invention provides a bed, an air passage formed in the bed, an air passage disposed in the air passage, and an air passage in the air passage. A regenerator unit for cooling the air, and a regenerative unit including at least a blow duct for discharging the air cooled by the regenerator through the air passage to the outside, wherein the blow duct is made expandable and contractible. (Claim 1).

[0007] The regenerative storage unit may be configured such that the blow-out duct is formed by sequentially stacking a plurality of box-shaped members whose size gradually increases.

[0008] The regenerative storage unit may be configured such that the blowing duct is formed by a bellows.

According to this configuration, when stopping the vehicle and taking a nap or the like, the blast of the cool storage unit is extended and the outlet from which the cool air is discharged is located at the upper part, so that the nap is performed. The cold air does not directly hit the person sleeping on the bed, making it more comfortable to use.
On the other hand, by keeping the blow-out duct in a contracted state while the vehicle is running, the view from the rear window and the side window is not obstructed by the blow-out duct.
