TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air conditioner for a truck cab having a refrigerant chamber provided below a nap bed.
[0002]
[Prior art]
Recently, freight transport by trucks has become longer and medium-sized and larger trucks are equipped with nap beds. The nap bed is provided in a bed space secured behind the driver's seat in the vehicle width direction. Conventional nap beds consist of a solid mat-shaped base made of Styrofoam cut so that it can be laid on the floor panel of the bed space, and a mat part laid on the top of the base. It consists of a felt cushion covering the top of the base and a vinyl skin covering the top surface.
On the other hand, in recent years, cold air has been stored in the cold storage material by using the refrigerant of the car air conditioner mounted on the truck, and after the car air conditioner has been activated, the cool air of the cold storage material has been led to the bed space to cool the area around the person in the nap bed 2. Description of the Related Art A regenerative cooler that cools with an air conditioner is known (for example, see Patent Document 1). This type of cool storage cooler is known as a vertical cooler in which a cool storage unit is mounted on the head side of a nap bed along a side wall in a vehicle cabin.
[0003]
However, since this cold storage unit is bulky in shape due to the structure in which the cold storage material is housed therein and the refrigerant guide pipe is inserted, if this cold storage unit is mounted on the head side of the nap bed, the bed space However, there was a problem that the livability deteriorated as a result of the sacrifice. Also, the driver's seat provided on the truck is configured so that the seat back can recline, but if this cold storage unit is mounted on a nap bed, the cold storage unit will interfere with reclining the seat back. There was a defect that could not be done.
In order to solve this problem, it has been proposed to provide a refrigerant chamber in the regenerative unit below the nap bed and to blow cool air in the refrigerant chamber from near the front end or the rear end of the nap bed via a duct (for example, , Patent Documents 2 and 3). If the refrigerant chamber is provided below the nap bed, bed space is not sacrificed, and reclining of the seat back in the driver's seat becomes possible.

[Problems to be solved by the invention]
However, when the refrigerant chamber is provided below the nap bed, and the other end of the duct communicating with one end is opened at the front end or the rear end of the nap bed to blow cool air, the opening at the other end of the duct is provided in the driver's seat. There was a problem that the driver was relatively far from the driver sitting. That is, the air conditioners in Patent Documents 2 and 3 can effectively air-condition around the nap bed during a nap in the nap bed, but blow the air around the driver's seat during normal running of the truck from the duct. There remains a problem that the air cannot be satisfactorily air-conditioned with the generated cold air.
An object of the present invention is to provide an air conditioner for a truck cab capable of air conditioning around a driver's seat while ensuring a reclining function and a bed space for the driver's seat.
