As a result, the cold food placed on one tray 20 is stored in the cold storage room 10 and the hot food is stored in the hot storage room 11, respectively, so that the cold storage or the cold storage is performed.
[0010]
Next, the structure of the tray receiver 19 and its mounting structure will be described in detail with reference to FIGS. In addition, about the attachment structure, the part attached to the heater panel 22 of the warm room 11 is mentioned as an example, and is demonstrated.
The structure of the warm room 11 will be described again. On the side surface of the warm room 11 opposite to the partition wall 7, the above-described heater panel 22 is stretched with a space from the side wall 1 </ b> A of the main body 1. Yes. The heater panel 22 is made of an aluminum plate, and as shown in FIG. 3, a flange 24 bent at right angles to the outside is formed on the front and rear vertical edges of the panel body 23. The projecting end of the flange 24 is arranged in a state of projecting to the vicinity of the side wall 1A, and a space 25 is formed between the side wall 1A of the panel main body 23.

[0011]
On the front and rear side edges of the panel body 23, a plurality of through holes 28 each having a long hole shape are formed in pairs. The position of the through hole 28 in each stage is a position slightly above the mounting position of the tray receiver 19. Inside the position where the through hole 28 is formed, a vertical guide member 30 is provided over almost the entire height. The guide member 30 is formed in an angle shape, and one surface 30A is applied to the heater panel 22 and fixed by driving rivets 31 into both upper and lower ends thereof, and the other surface 30B is a plate surface of the panel body 23. Standing up at a right angle. In addition, an introduction portion 32 is formed at the upper edge of each guide member 30, and this introduction portion 32 is arranged in a slanting posture that is perpendicular to the plate surface of the panel body 23 and whose upper end is inclined inward. ing. An inflow port 34 is formed at the lower edge of the panel body 23 at the center in the width direction.
[0012]
On the other hand, the heater unit 35 described above is mounted above the stretched position of the heater panel 22. As shown in FIG. 5, the heater unit 35 is equipped with a fan 36, and a lower surface thereof has a suction port 37 facing the warming chamber 11 side and a space 25 on the back side of the heater panel 22. A facing discharge port 38 is formed. Therefore, when the fan 36 is driven, warm air is discharged from the discharge port 38 and flows down along the back surface of the panel main body 23, and then flows from the lower end inlet 34 toward the bottom of the warming chamber 11. As shown in FIG. 3, a circulating flow is generated in which the air flows up through the gap between the trays 20 accommodated from the front and rear surfaces and is sucked from the suction port 37. By causing the warm air to flow down along the back surface of the panel body 23, the radiant heat from the heater panel 22 is made uniform over the entire surface.
Further, a part of the warm air blown out by the fan 36 is introduced from the introduction portion 32 and flows down outside the guide member 30, and it is blown into the position slightly above the tray 20 as a slightly warm air from the through hole 28. It is like that.
[0013]
Now, the tray receiver 19 is formed as follows. The tray receiver 19 is formed by bending a round pipe 40 made of stainless steel. As shown in FIG. 6, the tray receiver 19 is generally U-shaped as a whole, but the front and rear corners are U-shaped. It has a shape protruding outward. The dimension between the tips of the projecting portions 41 is set to be approximately the same as the dimension between the front and rear surfaces of the partition wall 7 described above. In addition, a resin coating 42 is applied to the overhanging portion 41 of the tray receiver 19 for heat protection.
[0014]
The mounting structure is as follows. Attachments 44 are provided at both ends of the tray receiver 19. This attachment 44 is also made of stainless steel and is formed in a thick disk shape with a larger diameter than the round pipe 40 constituting the tray receiver 19. 45 and 46 are formed. The end of the round pipe 40 is fitted into the inner mounting hole 45 and fixed by welding, and the base end side of the bolt 47 with a male screw 48 cut into the tip is inserted into the outer mounting hole 46. It is also fixed by welding.
[0015]
On the other hand, the panel main body 23 of the heater panel 22 is provided with insertion holes 50 for the bolts 47 at the front and rear side edges at each mounting position, and also on the mounting plate surface 30A of the guide member 30 with the bolts 47. The insertion hole 51 is opened in alignment with the insertion hole 50 of the panel body 23. In the tray receiver 19, bolts 47 projecting from the fixtures 44 at both front and rear ends are inserted from the front side into the insertion holes 50 and 51 of the heater panel 22 and the guide member 30 at the corresponding mounting positions. The flat washer 52 is passed through the protruding portion toward the back side, and then the U nut 53 is screwed and tightened to fix the heater panel 22.
When the tray receiver 19 is attached, the projecting portions 41 at the front and rear ends of the tray receiver 19 protrude to the position of the surface of the partition wall 7.
[0016]
Note that the tray receiver 19 having the same shape as described above is also used on the refrigerator compartment 10 side, and the bolt 47 protruding from the fixture 44 is inserted into the insertion hole 55 opened in the intermediate wall 6 to protrude to the back side. The U nut 53 is screwed and tightened to the portion via a flat washer 52 so that it can be attached in a posture facing the tray receiver 19 on the warming chamber 11 side.
In this case, the tray receiver 19 may be attached by being fastened together with a guide member disposed on the inner side of the intermediate wall 6 so as to guide the blowing of cold air.
[0017]
The present embodiment is configured as described above, and an example of its use will be described.
When housing a meal in a distribution car, the doors 14 of the cold storage room 10 and the warm storage room 11 that make a pair are opened, and a tray 20 on which cold food and hot food are served is inserted into the insertion groove 18 of the partition wall 7. Then, it is pushed in while being slid on the tray receiver 19 and stored. Since the protruding 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 both tray receivers 19, and the boundary portion 20 A is inserted into the insertion groove 18 of the partition wall 7. The operation can be performed almost simultaneously, and the tray 20 is smoothly pushed in without tilting the posture of the tray 20.
[0018]
Although detailed explanation is omitted on the refrigerator compartment 10 side, cold air generated in the cooler compartment 12 is blown into the intermediate wall 6 by a fan, blown out to the left and right refrigerator compartments 10 through the vent 6A, and blown out. The chilled air generates a circulation flow that is led to the cooler chamber 12 from a suction port provided on the ceiling surface of one of the refrigerator chambers 10, thereby cooling the left and right refrigerator compartments 10. Thereby, the cold food put on the tray 20 and accommodated in the refrigerator compartment 10 side is refrigerated.
[0019]
On the one side of the warming room 11, the inside of the warming room 11 is heated by the radiant heat from the heater panel 22 and the slightly warm air blown from the through hole 28, and is placed on the tray 20 and accommodated in the warming room 11 side. The cooked hot meal is stored in a hot store. Since the warm air blown out from the through hole 28 flows along the upper surface of the tray 20 and is considered not to directly hit the hot food, the temperature of the warming chamber 11 is not dried without drying the hot food. It works to increase the climb rate.
[0020]
According to this embodiment, the following many advantages can be obtained.
When the tray receiver 19 is attached to the heater panel 22 that is relatively inferior in mechanical strength on the warming chamber 11 side, 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. Therefore, high mounting strength can be obtained. Moreover, since the guide member 30 is provided in advance for blowing out the warm air into the warming chamber 11, the complexity of the structure is kept to a minimum.
[0021]
Since only the both ends of the tray receiver 19 are attached, dirt or the like is difficult to accumulate, and the tray receiver 19 itself is formed of the round pipe 40, so that it is easy to perform daily wiping and cleaning.
Further, when securing the mounting strength of the tray receiver 19, a structure is provided in which a large-diameter mounting tool 44 is provided only at the end portion serving as the mounting portion, and the portion that contributes to receiving the tray 20 is kept in a small diameter. Compared to the case where the entire pipe of the receiver 19 has a large diameter, a wide interval between the upper and lower tray receivers 19 can be secured.
[0022]
Since the tray receiver 19 is formed with a protruding portion 41 that protrudes to the vicinity of the surface of the partition wall 7, both side edges of the tray 20 are placed on both tray receivers 19, and the boundary portion 20 </ b> A is inserted into the partition wall 7. The operation of inserting into the groove 18 can be performed almost simultaneously, and the operation of storing the tray 20 can be performed smoothly.
Note that while the tray receiver 19 is heated to a high temperature on the warming chamber 11 side, the overhanging portion 41 protrudes toward the front side in the insertion direction of the tray 20 and is easily touched. However, the overhanging portion 41 has a resin coating. Since 42 is given, a hand does not touch a high temperature part.
