By flowing the warm air down along the back surface of No. 3, the radiant heat from the heater panel 22 is made uniform over the entire surface. A part of the warm air blown out by the fan 36 is introduced from the introduction part 32 and
The air flows down the outside of the tray 20 and is blown from the through hole 28 as a slightly warm air to a position slightly above the tray 20.

The tray receiver 19 is formed as follows. The tray receiver 19 is formed by bending a round pipe 40 made of stainless steel, and is generally U-shaped as shown in FIG. 6, but the front and rear corners are U-shaped. It has a shape protruding outward. The dimension between the tips of the overhangs 41 is set to be substantially the same as the dimension between the front and rear surfaces of the partition wall 7 described above. The overhanging portion 41 of the tray receiver 19 is provided with a resin coating 42 for heat insulation.

The mounting structure is as follows. At both ends of the tray receiver 19, attachments 44 are provided. The mounting member 44 is also made of stainless steel and is formed in a thick disk shape with a diameter larger than that of the round pipe 40 constituting the tray receiver 19. 45 and 46 are provided.

In the case where lunch is accommodated in the serving car, the doors 14 of the cold room 10 and the hot room 11 forming a pair are opened, and the trays 20 on which the cold food and the hot food are respectively loaded are inserted into the insertion grooves 18 of the partition wall 7. Then, it is pushed in while being slid on the tray receiver 19 and accommodated. Since the projecting portion 41 of the tray receiver 19 extends to the position of the surface of the partition wall 7, both side edges of the tray 20 are placed on the tray receivers 19, and the boundary portion 20A is inserted into the insertion groove 18 of the partition wall 7. The operations can be performed almost simultaneously, and the tray 20 can be pushed in smoothly without tilting the posture of the tray 20.

On the refrigerator compartment 10 side, although not described in detail, the cool air generated in the cooler compartment 12 is blown into the intermediate wall 6 by a fan and blown out to the left and right refrigerator compartments 10 through the vent 6A. The chilled air blown out generates a circulating flow such that it is led to a cooler room 12 from a suction port provided on the ceiling surface of one of the refrigeration rooms 10, and thus the left and right refrigeration rooms 1
0 is cooled. Thus, the cold food placed on the tray 20 and stored in the refrigerator compartment 10 is refrigerated.

On the other hand, the heater panel 2
The inside of the storage room 11 is heated by the radiant heat from 2 and the slightly warm air blown from the through hole 28, and the hot food placed on the tray 20 and stored in the storage room 11 side is stored. Through hole 2
8 is designed to flow along the upper surface of the tray 20 so as not to directly hit the hot food, so that the hot food can be dried without drying the hot food. It works to enhance.

According to this embodiment, the following advantages can be obtained. When the tray receiver 19 is mounted on the heater panel 22 having relatively low mechanical strength on the side of the preservation chamber 11, the end of the tray receiver 19 is fastened together with the guide member 30 disposed on the back side of the heater panel 22. As a result, high mounting strength can be obtained. In addition, since the guide member 30 is provided in advance to blow out the slightly warm air into the storage room 11,
The complexity of the structure is kept to a minimum.

Since only the both ends of the tray receiver 19 are attached, dirt and the like are less likely to accumulate, and the tray receiver 19 itself is formed of the round pipe 40, so that daily wiping and cleaning can be easily performed. Further, in order to secure the mounting strength of the tray receiver 19, a structure is adopted in which the large-diameter mounting tool 44 is provided only at the end portion serving as the mounting portion, and the portion contributing to receiving the tray 20 is kept at a small diameter. Compared to the case where the entire pipe of the receiver 19 is made large in diameter, a wider space between the upper and lower tray receivers 19 can be secured.

The tray receiver 19 is formed with an overhanging portion 41 protruding to the vicinity of the surface of the partition wall 7, so that both side edges of the tray 20 can be placed on the tray receivers 19 and the boundary portion 20A can be formed by the partition wall. The operation of inserting the tray 20 into the insertion groove 18 can be performed almost simultaneously, and the operation of housing the tray 20 can be performed smoothly. In the storage room 11, the tray receiver 19 is heated to a high temperature, while the overhanging portion 41 projects to the near side in the insertion direction of the tray 20 so that the hand can be easily touched. 42
The hand does not touch hot parts.
