Abstract

PROBLEM TO BE SOLVED: To efficiently generate the hot air, and prevent the excessive temperature rise of a heater mounting plate by providing the blow outlet of a fan in such a state as oriented toward the heater mounting plate, in the structure where the air drawn from a heat reserving cabinet is blown to a heater on the operation of a motor and changed to the hot air for circulation to the heat reserving cabinet. SOLUTION: In a cold temperature delivery vehicle, a heater 45 is fed with electric power, when a power supply is turned on, and heat is thereby generated. Concurrently, a fan 48 is rotated. As a result, air within a heating cabinet 20 is drawn from a vent hole 34 formed on a ceiling plate 33 via a suction chamber 35, and blown from a blow outlet 57 to the heater 45. Air is thereby changed to the hot air. This hot air is circulated and fed to the heating cabinet 20 from a wind opening 31 formed on a division 29. In this case, the blow outlet 57 of the fan 48 is provided, so as to be oriented toward a heater mounting plate 40 via a slant plate 56. According to this construction, the air supplied from the fan 48 is preheated via heat exchange with the heater mounting plate 40 kept in a heated condition, and the excessive temperature rise of the heater mounting plate 40 is prevented.

Since the blower outlet 57 of the fan 48 is provided by the inclined plate 56 so as to be directed toward the heating body mounting plate 40, most of the blown air is first directly directed to the heating body mounting plate 40. The heating element 45 is applied and reflected there.
Turned to That is, the air blown out from the fan 48 is further heated by the heating element 45 from the state where it is preheated by heat exchange with the heating element mounting plate 40 in the heating state, so that it is efficiently heated to warm air. To be converted.

The fact that the air blown from the fan 48 is applied to the heating element mounting plate 40 as described above causes heat exchange,
The temperature rise of the heating element mounting plate 40 is reduced. Further, since the heating body mounting plate 40 itself is mounted via the gap forming plate 37 and the gap 41 is formed between the heating body mounting plate 40 and the side wall 23, it is difficult for the heat of the heating body mounting plate 40 to be transferred to the side wall 23. And therefore the insulation 27 of the side wall 23
Is prevented from adversely affecting. Further, the heating chamber thermos 62 is installed on the back surface side of the wall plate 50 that constitutes the outlet 57, and the air blown from the fan 48 is heated by the heating chambers thermos 62.
The hot air is efficiently circulated and supplied without hitting.

If the rotation of the fan 48 is stopped during the heating operation, the circulation of the air will be stagnant and the temperature in the vicinity of the heating body 45 may be excessively increased. However, fan 4
8 is stopped, the radiant heat of the heating element 45 is
As indicated by the broken line arrow c in FIG. 3, air having a high heat transfer coefficient is used as a medium, and the thermo mounting plate 67 is swiftly mounted on the rising flow.
It reaches the lower surface of the mounting surface 68 of No. 2 and is detected by the temperature sensing unit 64 of the heating chamber thermo 62 through the opening 69. This prevents the heating body 45 from being energized and prevents the heating chamber 30 from excessively rising in temperature, thereby preventing the heat insulating material 27 and the fan 48 from being adversely affected.

Further, since the mounting surface 68 of the thermo mounting plate 67 closes the lower end of the gap 49, the radiant heat that should hit the temperature sensing portion 64 is prevented from escaping, and it is possible to detect with good response. In addition, the main body 63 of the heating chamber thermo 62
Are housed in the void 49, and the drawn electric wire 75 is routed through the void 49, so that it is avoided that heat is applied to them.
