Are configured to communicate with each other.
[0013]
A cord heater (heater) 50 is arranged in a meandering manner over a predetermined area in the vertical direction on the back surface (wall surface facing the heating path 44) of the heater panel 34 corresponding to the heating path 44. The warm storage room 20 is kept warm by the radiant heat of the heater panel 34 heated by the heater 50 and the warm air heated by the cord heater 50. The cord heater 50 is connected to a power source via a power cord (not shown) drawn from the upper opening of the duct 32. One location corresponding to the vicinity of the lower end of each air passage 46 in the heater panel 34 (duct 32), that is, one location in the area where the heating passage 44 and the air passage 46 communicate with each other below the lower end of the partition plate 42 is shown in FIG. As shown in FIG. 3, a lower air outlet (air outlet) 52 that connects the air passage 46 and the warming chamber 20 is formed. Further, in the heater panel 34 (duct 32), on the upper side from the middle in the vertical direction corresponding to each air passage 46, as shown in FIG. And an upper outlet (air outlet) 54 is formed. That is, the warm air that has flowed into the air passages 46 from the heating passages 44 is blown out from the air outlets 52 and 54 to the warming chamber 20. In the embodiment, the lower air outlet 52 and the upper air outlet 54 have two air outlets formed in parallel at the same location (level).
[0014]
On the surface of the heater panel 34 in the duct 32, a locking portion (not shown) is disposed at a position where it does not interfere with the air outlets 52, 54, and the tray receiver 26 is interposed via the locking portion. It is fixed to the duct 32.
[0015]
A fan (not shown) is disposed above the duct 32, and by operating the fan, the air inside the warming chamber 20 is transferred from the inlet 44 a opened at the upper part of the duct 32 to the heating path 44. Configured to blow. Accordingly, the air blown into the heating path 44 is lowered while being heated by the cord heater 50, flows into the air blowing paths 46, 46 through the communication portions 48, 48, and rises through the air blowing paths 46. The air is blown out from the air outlets 52 and 54 to the warming room 20. In addition, when the air descends in the heating path 44, the radiant heat of the heater panel 34 heated by the cord heater 50 is made uniform over the entire surface.
[0016]
[Effect of the embodiment]
Next, the operation of the warming structure in the distribution vehicle according to the embodiment will be described below. When the operation of the arrangement vehicle 10 is started, the cord heater 50 is energized, the heater panel 34 that is in contact with the heater 50 is heated, and the inside of the warming chamber 20 is kept warm by the radiant heat of the panel 34. Also, the fan disposed above the duct 32 is operated, and the air in the warming chamber 20 is blown into the heating path 44 through the blowing port 44a, and the cord heater is lowered while lowering the heating path 44. After being heated at 50 and turned into hot air, it flows into the air blowing paths 46 and 46 through the communication parts 48 and 48. In addition, when air flows through the heating path 44, the radiant heat of the heater panel 34 is made uniform throughout.
[0017]
As shown in FIG. 1, a part of the warm air flowing into each air passage 46 is blown into the warming chamber 20 from the lower outlet 52 formed near the lower end thereof. Moreover, the warm air which goes up the ventilation path 46, without blowing from the lower blower outlet 52 is warm chamber 20 from each of each upper blower outlet 54 currently formed in the several upper part rather than the middle of the up-down direction. Be blown in.
[0018]
That is, since the lower outlet 52 is formed only at one location on the lower side of the air passage 46, when the heating passage 44 and the air passage 46 are narrowed by reducing the thickness of the duct 32 (inner wall) Even when the space between the heater 28 and the heater panel 34 is narrow), it is possible to prevent a large amount of hot air from being blown out to the lower side of the warming chamber 20. Accordingly, the amount of warm air rising to the upper side of the air passage 46 does not decrease, and sufficient warm air can be blown from the upper outlet 54 to the upper side of the warming chamber 20. It is possible to prevent room temperature variations from occurring in the upper and lower positions.
[0019]
Here, when manufacturing the main body 12, unevenness may occur on the duct arrangement surface of the inner wall 28 due to foaming of the heat insulating material or the like. However, in the allocation vehicle 10 of the embodiment, since the packing 40 is interposed in the entire contact portion between the duct 32 and the inner wall 28, a gap is generated between the two even if the inner wall 28 is uneven. Is prevented by the packing 40. Accordingly, it is possible to prevent the warm air from leaking from the portion other than the air outlets 52 and 54 in the duct 32 into the warming chamber 20 and further suppress the occurrence of variations in room temperature in the warming chamber 20.
[0020]
The hot air outlets formed corresponding to the respective air passages are not limited to the configuration of the embodiment, and the air outlets are formed at equal intervals over the entire vertical direction of the air passages. It may be. Further, the type of the heater disposed in the duct is not limited to the cord heater, and other types of heaters can be appropriately employed. Furthermore, in the embodiment, the heater is disposed on the back side of the heater panel in the duct, but can be disposed on the inner wall side facing the heating path.
[0021]
【The invention's effect】
