A single unit without a supporting arm and a tray receiver is prepared, and is detachably attached to the ceiling surface of the main body 1 for example.

This embodiment has the structure as described above,
Next, the operation will be described. When forming the partition wall 5, first, the partition unit 56 is assembled in the same manner as described above. Repeatedly briefly, the reinforcing member 45 is fitted in the mounting position of the unit partition wall 25, the mounting portions 43 of the pair of support arms 27H and 27C are applied to both surfaces of the mounting position, and the rivet 50 is mounted together with the reinforcing member 45. It is fixed by being driven in, and the tray receivers 22H and 22C are attached to the projecting ends of both the support arms 27H and 27C, respectively, with the flat head screw 5
Fixed at 7. On the other hand, in the duct 9 that forms the wall surface of the refrigerating chamber 7 and the heater panel 16 that forms the wall surface of the warming chamber 6, a pair of front and rear supporting members 58C and 58H are provided.
It is attached in a facing manner over a plurality of stages.

The partition units 56 are assembled in order from the lower side, for example. As shown in FIG. 9, the procedure is as follows.
In a slanted position, with the fitting hole 6 of the mounting surface 53
1 is inserted into the round pin 60 of the support 58C on the refrigerating compartment 7 side. Next, when the tray receiver 22H on the heating chamber 6 side is placed in a horizontal posture so as to be lowered, the shaft portion 67 of the screw 65 of the support tool 58H on the heating chamber 6 side is attached to the tray receiver 22H on the heating chamber 6 side. It enters into the fitting hole 68 of the surface 53 from the lower side through the introduction groove 69, and the fitting hole 68 is received by the shaft portion 67 of the screw 65. Then, when the screw 65 is screwed in, the mounting surface 53 of the tray receiver 22H is clamped and fixed between the head portion 66 and the end surface of the main body portion 63 of the support tool 58H. In the same manner, the other partition units 56 are assembled so that they are sequentially stacked from the lower side. Finally, the uppermost unit partition wall 25 is assembled.

When all the unit partition walls 25 are assembled, the front and rear movable members 30 and stopper members 36 of each unit partition wall 25 are attached to the upper surface of the unit partition wall 25 below by the elastic force of the leaf springs 32 and 37. It comes into contact (see FIG. 6). The movable member 30 and the stopper member 36 of the lowermost unit partition wall 25 are in contact with the upper surface of the base 24. As a result, the partition wall 5 is constructed that insulates the pair of heating chamber 6 and refrigerating chamber 7 from each other in a heat insulating manner. At the same time, a pair of left and right tray receivers 22H and 22C are provided on the wall surface of the pair of hot and cold storage chambers 6 and 7 opposite to the partition wall 5.
Are arranged over a plurality of stages. At the bottom, the tray receivers 22H, 2 that are not unitized are
2C is prepared and directly mounted on the mounting wall surfaces of both chambers 6 and 7.

In the case of housing meals in the car, after opening the doors 8 of the hot and cold rooms 6 and 7 forming a pair, the tray 20 on which the hot and cold foods are placed is set in units of the boundary 20A. The guide member 33 of the movable member 30 mounted on the partition wall 25 is pressed against the guide portion 33. Then, the movable member 30
While being lifted against the elastic force of the leaf spring 32, the boundary portion 20A splits between the movable member 30 and the upper surface of the unit partition wall 25 therebelow, and both side edges of the tray 20 are separated from the guide portion 54. The tray receivers 22H and 22C are pushed onto the mounting surfaces 52 and pushed in while sliding, and the rear end of the tray 20 abuts on the stopper member 36 to complete the accommodation. At this time, since the movable member 30 is pressed against the boundary portion 20A of the tray 20, the heat insulating room 6 and the refrigerating room 7 are kept in a heat insulating state.

Here, as described above, each partition unit 56 has a reinforcing member 45 inside the mounting position of the unit partition wall 25.
And the mounting portions 43 of the support arms 27H and 27C are fastened together by the reinforcing member 45 and the rivet 50 on both left and right sides.
The H and 27C and the unit partition wall 25 can be formed as one rigid body, so to speak. Therefore, both support arms 27C and 27H
The tray receivers 22C and 22H provided at the projecting ends of the screws are fitted with the round pins 60 into the fitting holes 61 on the refrigerating chamber 7 side, and the shaft portion 67 of the screw 65 is passed through the fitting holes 68 in the warming chamber 6 as well. Even with a simple mounting structure in which the screw 65 is simply screwed in, both support arms 2 are
The unit partition wall 25 does not fall while the 7H and 27C are inclined so as to form a V-shape on the front. Therefore, a gap is formed between the upper unit partition wall 25 and the movable member 30, and the heat insulation between the two chambers 6 and 7 is impaired. Does not cause a problem that the tray 20 is firmly pressed and it becomes difficult to insert the tray 20.

The inside of the heating chamber 6 is heated by the radiant heat from the heater panel 16, and the hot food on the tray 20 accommodated therein is brought into a heating state. On the other hand, on the refrigerating compartment 7 side, the cooler compartment 1
The cold air blown into the both ducts 9 from the vent hole group 10
And the trays 2 accommodated therein are cooled by generating a circulating flow such that they are blown out to the left and right refrigerating compartments 7 and then guided into the cooler compartment 12 from the ceiling side of one refrigerating compartment 7.
Cold food above 0 is refrigerated. Here, when the trays 20 are accommodated in the same stage from both front and rear sides, as shown in FIG. 10A, the gap between the front and rear trays 20 in the refrigerating chamber 7 is closed by the support arm 27C. However, since the support hole 27C is provided with the through hole 44, it is ensured that the cool air flows in the vertical direction, and the refrigerating chambers 7 of the respective stages are uniformly cooled.

When the tray 20 is taken out, it may be pulled out in a direction opposite to the inserting direction. Further, the tray according to the present embodiment can be used in a so-called pass-through mode in which the tray 20 accommodated from the front side is taken out from the rear side or vice versa. For example, tray 2 from the front side
When 0 is inserted, the push-in is once restricted by the stopper member 36, but when it is further pushed in, the boundary portion 20A is pushed against the guide portion 38 (see FIG. 4) of the stopper member 36, and as shown in FIG. While the member 36 is lifted up against the elastic force of the auxiliary leaf spring 37, the boundary portion 20A breaks in and the tray 20 can be moved to the rear surface side. Since the tray 20 has the pass-through function, for example, although it is desired to keep the tray 20 on the front side, the tray 20 shown in FIG.
As shown in 0 (B), the tray 20 may break into the position of the stopper member 36. In that case, the back side of the tray 20 is in a state of blocking the upper side of the support arm 27C having the through hole 44, but conversely, since there is a gap on the front side of the tray 20, the flow of cold air is not interrupted. Absent.

On the other hand, when the tray 20 is taken in or out, juice or the like is spilled, and the unit partition wall 25 and the tray receiver 22H,
22C may be attached, so it is necessary to clean it appropriately. In that case, each partition unit 56 is sequentially removed. For example, contrary to the above assembling procedure, the uppermost unit partition wall 25 may be removed and then sequentially removed from the top. The procedure for removing the partition unit 56 is as follows. After loosening the screw 65 that has fixed the tray receiver 22H on the side of the heating chamber 6, the tray receiver 22H side is lifted and the fitting hole 68 is attached to the shaft portion 67 of the screw 65. It suffices to pull out the upper part, subsequently shift the entire partition unit 56 toward the heating chamber 6 side, pull out the fitting hole 61 of the tray receiver 22C on the cooling chamber 7 side from the round pin 60, and finally pull out to the opening side. Then, the partition unit 56 may be cleaned by washing with water or the like.

It should be noted that it is possible to remove only the partition unit 56 where the stain is attached and only a part of the stain is attached for cleaning. In that case, the partition unit 5 you want to remove
When the screws 65 of the tray receiver 22H on the side of the heating chamber 6 in 6 are loosened and the tray receiver 22H is likewise lifted, as shown in FIG. 11, the movable member 30 and the stopper mounted on the unit partition wall 25 thereabove. Since the partition unit 56 is tilted while the member 36 is pushed up and the fitting hole 68 of the tray receiver 22H is pulled out above the shaft portion 67 of the screw 65, similarly, the partition unit 56 as a whole is similarly moved to the heating chamber 6 side. The fitting hole 61 of the tray receiver 22C on the refrigerating compartment 7 side may be pulled out from the round pin 60 and pulled out to the opening side. Even after the cleaning is completed, the movable unit 30 and the stopper member 36 of the unit partition wall 25 above it can be pushed up to secure the tilting allowance space of the partition unit 56, and can be similarly assembled.

As described above, according to this embodiment,
The unit partition wall 25 and both tray receivers 22H and 22C are connected via supporting arms 27H and 27C to form a unit as a partition unit 56. When mounting the unit, the mounting surface of the tray receiver 22C on the refrigerating compartment 7 side is attached. 5
After inserting the fitting hole 61 of No. 3 into the round pin 60 of the corresponding support tool 58C, the fitting hole 68 of the mounting surface 53 of the tray receiver 22H on the side of the heating chamber 6 was provided in the corresponding support tool 58H. By fitting the shaft portion 67 of the screw 65 from below through the introduction groove 69, and then screwing in the screw 65,
It can be installed easily and firmly. On the other hand, when removing, contrary to the above, after loosening the screw 65, the tray receiver 22H on the heating chamber 6 side is lifted to pull out the fitting hole 68 above the shaft portion 67 of the screw 65, and then the partition It can be removed by shifting the entire unit 56 toward the heating chamber 6 side, pulling out the fitting hole 61 of the tray receiver 22C on the cooling chamber 7 side from the round pin 60, and finally pulling it out toward the opening side. That is,
By loosening or screwing in the screws 65 without completely removing them, the partition unit 56 can be easily removed or attached for each unit, which is extremely convenient when cleaning or the like.
