JP-A-11-222936

  In the prior art, the temperature in the warehouse becomes very high during the hot summer season, and there is a risk of heat stroke when a driver delivering door-to-door delivery works in the warehouse. Because of the door-to-door delivery, the distance from the delivery location to the next delivery location is short, and the traveling speed of the vehicle is low. Therefore, it is generally impossible to ventilate the inside of a warehouse with a small and partial ventilation port used for an aluminum van.

  Further, in the prior art, when taking in the outside air, it may be affected by the direction of the wind flow and ventilation may not be possible. For this reason, if an air conditioner such as an air conditioner is introduced, the problem can be solved relatively easily. However, it is expensive and heavy, and as a result, the fuel consumption is also deteriorated.

  By the way, the cargo stored in the warehouse does not need to be cooled because goods that do not require refrigeration, foamed polystyrene cases for each household, and food and dry ice are contained in the case.

  In general, it is considered that the temperature inside the cabinet does not rise in a heat insulation van type vehicle with a heat insulating material around it, but because the movement distance is short and the doors are frequently opened and closed, the temperature inside the cabinet is quickly Will rise. Further, even in a heat insulation van type vehicle, the temperature in the warehouse rises due to direct sunlight. In fact, an insulated van type vehicle is more gradual than “Dry Dan” but may eventually become hot. Conversely, even if the outside air temperature drops in the evening, the temperature inside the cabinet is less likely to drop in the insulated van type vehicle due to the heat insulation effect compared to the dry car.

  For this reason, although it is possible to attach a small air blower in a store | warehouse | chamber, in such a case, sufficient effect cannot be acquired only by stirring hot air.

As a result, as shown in the flow A, the outside air passes through the front outer communication port 15, the first through hole 18, and the second through hole 36 from the front inner communication port 16 to almost the full width of the front wall 4. It is possible to flow into the interior 2A. Similarly, at the left and right side ventilation openings 20 and 21, the left and right side inner opening / closing bodies 40 can be slid to allow outside air to flow into the interior 2A from substantially the entire width before and after the left and right side walls 5 and 6. When the internal pressure of the internal chamber 2A increases due to the outside air flowing into the internal chamber 2A, the hot air in the internal chamber 2A flows from the rear surface inner communication port 31 through the rear surface communication portion 32 through the rear surface outer communication port 30 as shown by flow B. Released into the open air. As a result, in the interior 2A, the outside air is introduced from the front ventilation port 14 and the left and right side ventilation ports 20 and 21, and further exhausted from the rear ventilation port 29, it is possible to ventilate every corner of the interior 2A. .

  Further, when it rains, the front rain intrusion prevention body 19, the left and right side rain intrusion, even if rain enters the front outside communication port 15, left and right side outside communication ports 22, 23, and the rear outside communication port 30, as shown in the flow C. The blocking body 33 and the rear rain entry blocking body 34 prevent the front inner communication port 16, the left and right side inner communication ports 24 and 25, the rear surface inner communication port 31 side, and thus the penetration into the interior 2A. It should be noted that the continuous provision of the ventilation openings in the left-right direction or the front-rear direction includes cases where the vents are substantially continuous, such as being unable to be provided at the end of the cargo box body 2, or intermittently.

  As described above, in the above-described embodiment, the front ventilation port 14 is continuously formed on the front wall 4 of the packing box body 2 and the upper portions of the left and right side walls 5 and 6, which are referred to as so-called dryons, which are not provided with a heat insulating material. By providing left and right side ventilation ports 20 and 21 and continuously providing a rear ventilation port 29 in the upper part of the rear wall 7, it is possible to cope with wind flow in all directions in the interior 2A even at low speeds. it can. The front ventilation port 14 and the like are made of, for example, an aluminum mold having an interval between the outer wall plate portion 9 and the inner wall plate portion 10 of about 25 mm, and the front outer communication port 15 and the front inner communication port 16 are spaced between these intervals. In addition, there is a front rain intrusion prevention body 19, and when loading the luggage in the warehouse 2A, there is no projecting part inside the warehouse 2A by the front vent 14 etc. Can be stacked. Therefore, it is possible to secure a load capacity equivalent to that of the body other than the ventilation port specification. Further, since the front outer communication port 15 and the like do not protrude outward, there is no possibility of a hook accident during traveling. Moreover, since a complicated mechanism and expensive parts are not used, it can be manufactured at low cost.

  Moreover, in the past, it was necessary to install ventilation openings avoiding vertical and horizontal skeletons, but the front communication part 17, the left and right side communication parts 26 and 27, and the rear communication part 32 were each duct-shaped, and the cargo box body By forming the upper skeleton 2, the front surface communication portion 17, the left and right side surface communication portions 26, 27 and the rear surface communication portion 32 can be arranged as high as possible on the top of the cargo box body 2.

Since heat of an engine and an exhaust pipe (both not shown) is not directly taken in, ventilation can be performed without being affected by these heat effects.

  Moreover, the ceiling 8 is heated by direct sunlight, and the ceiling 8 in the cabinet 2A is also heated. Hot air accumulates in the upper part of the chamber 2A, but outside air that has entered from any of the front vents 14, left and right side vents 20, 21 and rear vent 29 is facing along the ceiling 8 in the chamber 2A. It is possible to discharge the hot air in the storage 2A and prevent the temperature in the storage 2A from rising.

  Furthermore, the front ventilation port 14, the left and right side ventilation ports 20, 21 and the rear ventilation port 29 are provided all around the upper part of the interior 2A, so the direction of the wind flow is not selected. Heat accumulation can be prevented, and heat accumulation in the interior 2A can be prevented. Therefore, the heat of the ceiling 8 and the hot air in the interior 2A can be effectively released outside the compartment even when the vehicle is running or stopped. Thus, ventilation that does not select the direction in which the wind bends can suppress the rise in temperature in the cabinet 2A and prevent heat accumulation, so that the work environment in the cabinet 2A can be improved. In particular, even when a load is loaded from the front side of the floor board 3 and the front vent 14 is blocked, the heat in the cabinet 2A is exhausted by the left and right vents 20, 21 and the rear vent 29, so The working environment can be improved.

  In addition, the front ventilation entry 14, the left and right ventilation openings 20, 21 are provided with a front rain entry prevention body 19, a left and right side rain entry prevention body 33, and the rear ventilation entry 29 is also provided with a rear rain entry prevention body 34. Therefore, it is possible to prevent rainwater from entering.

  Moreover, the front ventilation opening 14, left and right side ventilation openings 20, 21 are equipped with a front inner opening / closing body 35, left and right side inner opening / closing body 40, etc. It can be operated from 2A to perform ventilation blocking work. In particular, when opening the front ventilation opening 14 and the left and right ventilation openings 20, 21, turn the fixed knob 38 to loosen it, and slide the front inner opening / closing body 35 and the left / right side inner opening / closing body 40 and close them in reverse order. It was made to operate with. On the other hand, since a general simple ventilator is operated from the outside when opening and closing, a stepladder or the like is often required.

  Further, since the rear ventilation opening 29 is provided at the upper part of the rear frame 7A, it is not affected by the type and shape of the door, so that the opening of the rear frame 7A can be secured.

  FIG. 7 shows the second embodiment, and the same parts as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In the second embodiment, the rear vent 29 'is provided in the upper part of the rear frame 7A in the left and right positions and rearward along the left and right directions, and is formed on the rear outer communication port flush with the rear frame 7A. 30 'and a rear inner communication port 31' formed in the inner wall plate portion 13 are connected to each other to have a rear surface communication portion 32 'communicating the interior 2A and the outside thereof, from the rear outer communication port 30'.
