The tray receivers 22C and 22H of each partition unit 56 are attached to the duct 9 (intermediate wall 3) of the refrigerator compartment 7 and the heater panel 16 of the refrigerator compartment 6, respectively.
Therefore, a pair of front and rear support members 58C are provided on the intermediate wall 3 of the refrigerator compartment 7 in a plurality of stages. As shown in FIG. 7, the support 58C has a shape in which a round pin 60 protrudes from the center of the main body 59. A pair of front and rear fitting holes 61 into which the round pins 60 can be fitted are formed in the mounting surface 53 of the tray receiver 22C disposed on the refrigerator compartment 7 side.
[0022]
On the other hand, the heater panel 16 of the storage compartment 6 is also provided with a pair of front and rear supports 58H in a plurality of stages. As shown in FIG. 8, this support 58H has a structure in which a screw hole 64 is cut at the center of the main body 63, and a screw 65 with a head 66 is screwed into the screw hole 64. Similarly, a pair of front and rear fitting holes 68 are formed on the mounting surface 53 of the tray receiver 22 </ b> H disposed on the storage compartment 6 side. The fitting hole 68 is formed to have a size in which the shaft portion 67 of the screw 65 can be fitted and hooked to the head 66 thereof. An introduction groove 69 that can be inserted into the fitting hole 68 by passing through the portion 67 from below is formed to open at the lower edge of the mounting surface 53.
The unit partition wall 25 arranged at the uppermost stage is prepared as a single unit without a support arm and a tray receiver, and is detachably attached to, for example, a ceiling surface of the main body 1 in a suspended manner.
[0023]
The present embodiment has the above-described structure, and its operation will be described below. When the partition wall 5 is formed, first, the partition unit 56 is assembled in the manner described above. When simply repeated, the reinforcing member 45 is fitted into the mounting position of the unit partition wall 25, and the mounting portions 43 of the pair of support arms 27H and 27C are applied to both surfaces of the mounting position. The tray holders 22H and 22C are fixed to the projecting ends of the two support arms 27H and 27C with the flathead screws 57, respectively. On the other hand, a pair of front and rear support members 58C and 58H are attached to the duct 9 forming the wall surface of the refrigerating room 7 and the heater panel 16 forming the wall surface of the refrigerating room 6 in a plurality of stages so as to face each other.
[0024]
Each partition unit 56 is assembled sequentially, for example, from the lower side. As shown in FIG. 9, the procedure is as follows: the partitioning unit 56 is placed in an oblique position with the tray receiver 22C on the refrigerator compartment 7 side down, and the fitting hole 61 of the mounting surface 53 is inserted into the support 58C on the refrigerator compartment 7 side. Into the round pin 60. Next, when the tray receiver 22H on the storage compartment 6 is set to a horizontal position so as to be lowered, the shaft 67 of the screw 65 of the support 58H on the storage compartment 6 is attached to the tray support 22H on the storage compartment 6 side. It enters the fitting hole 68 of the surface 53 from below through the introduction groove 69, and the fitting hole 68 is received by the shaft 67 of the screw 65. When the screw 65 is screwed in, the mounting surface 53 of the tray receiver 22H is sandwiched and fixed between the head 66 and the end surface of the main body 63 of the support tool 58H. In the same manner, the other partition units 56 are assembled so as to be sequentially stacked from the lower side. Finally, the uppermost unit partition wall 25 is assembled.
[0025]
When all the unit partition walls 25 are assembled, the front and rear movable members 30 and the stopper members 36 in each unit partition wall 25 abut on the upper surface of the unit partition wall 25 thereunder by the elasticity of the leaf springs 32 and 37. State (see FIG. 6). In addition, the movable member 30 and the stopper member 36 of the lowermost unit partition wall 25 abut on the upper surface of the base 24. As a result, the partition wall 5 for insulating the pair of the warming room 6 and the cold room 7 in a heat-insulating manner is constructed.
At the same time, a pair of left and right tray receivers 22H and 22C are arranged in a plurality of stages on the wall surface opposite to the partition wall 5 in the paired warming room 6 and cold room 7. At the lowermost stage, tray receivers 22H and 22C which are not unitized are prepared, and are directly mounted on the mounting wall surfaces of both chambers 6 and 7.
[0026]
In the case of storing meals in the catering car, after opening the doors 8 of the hot room 6 and the cold room 7 forming a pair, the tray 20 on which hot food and cold food are respectively filled is placed, and the boundary portion 20A is divided into unit partition walls 25. Is pushed in such a manner that it comes into contact with the guide portion 33 of the movable member 30 attached to the movable member. Then, while the movable member 30 is lifted up against the elasticity of the leaf spring 32, the boundary portion 20 </ b> A is split between the movable member 30 and the upper surface of the unit partition wall 25 below the movable member 30, and both side edges of the tray 20 are moved. Is slid from the guide portion 54 onto the mounting surface 52 of the tray receivers 22H and 22C and is pushed in while sliding, and the inner end of the tray 20 hits the stopper member 36, thereby completing the storage. At this time, since the movable member 30 is pressed against the boundary portion 20A of the tray 20, the space between the warming room 6 and the cold room 7 is kept insulated.
[0027]
Here, as described above, each partition unit 56 fits the reinforcing member 45 inside the mounting position of the unit partition wall 25, and attaches the mounting portions 43 of the support arms 27H and 27C to the left and right surfaces on both sides of the reinforcing member 45 and the rivet 50. Therefore, the support arms 27H and 27C and the unit partition wall 25 can be formed as a single rigid body. Therefore, the tray receivers 22C and 22H provided at the protruding ends of the support arms 27C and 27H are fitted in the refrigerating chamber 7 only by fitting the round pins 60 into the fitting holes 61. Even with a simple mounting structure in which the screw 67 is simply screwed into the fitting hole 68 through the fitting hole 68, a unit from the unit 20 while receiving a load from the tray 20 while tilting the support arms 27H and 27C so as to form a front V-shape. The partition wall 25 does not go down. Accordingly, a gap is formed between the movable member 30 of the unit partition wall 25 thereon and heat insulation between the two chambers 6 and 7 is impaired. Is not pressed firmly and it is difficult to insert the tray 20.
[0028]
The inside of the warming room 6 is heated by the radiant heat from the heater panel 16, and the hot food on the tray 20 accommodated therein is kept warm. On the other hand, on the refrigeration room 7 side, the cool air blown into the two ducts 9 from the chiller room 12 is blown out to the left and right refrigeration rooms 7 through the ventilation port group 10, and then the chiller is cooled from the ceiling side of one of the refrigeration rooms 7. A circulating flow, such as being guided into the chamber 12, is generated and cooled, and the cold food on the tray 20 accommodated therein is refrigerated. Here, when the trays 20 are accommodated in the same step from both front and rear sides, as shown in FIG. 10A, the gap between the front and rear trays 20 in the refrigerator compartment 7 is closed by the support arm 27C. However, since the through-hole 44 is opened in the support arm 27C, it is ensured that the cool air flows in the vertical direction, and the refrigerating chambers 7 in each stage are cooled without variation.
[0029]
When taking out the tray 20, it is only necessary to pull out the tray 20 in the direction opposite to the insertion direction. In addition, the serving truck of the present embodiment can be used in a so-called pass-through configuration in which the tray 20 accommodated from the front side is taken out from the rear side, or vice versa. For example, when the tray 20 is inserted from the front side, the pushing is once restricted by the stopper member 36, but when the tray 20 is further pushed, the boundary portion 20A is pressed against the guide portion 38 (see FIG. 4) of the stopper member 36, and FIG. As shown in (2), while the stopper member 36 is lifted against the elasticity of the auxiliary leaf spring 37, the boundary portion 20A breaks into the stopper member 36, and the tray 20 can be moved to the rear surface side.
Due to the pass-through function, for example, the tray 20 may break into the position of the stopper member 36 as shown in FIG. There is. In this case, the rear side of the tray 20 blocks the upper part of the support arm 27C having the through hole 44, but on the contrary, a gap is formed on the front side of the tray 20, so that the flow of cool air is not interrupted. Absent.
[0030]
On the other hand, juice or the like may be spilled when the tray 20 is taken in and out, and may adhere to the unit partition wall 25 and the tray receivers 22H and 22C. At that time, the partition units 56 are sequentially removed. For example, contrary to the above-described assembling procedure, the uppermost unit partition wall 25 may be removed and then sequentially removed from above. The procedure for removing the partition unit 56 is as follows. After loosening the screw 65 holding the tray receiver 22H on the storage chamber 6 side, lift the tray receiver 22H side, and fit the fitting hole 68 into the shaft part 67 of the screw 65. Then, the entire partitioning unit 56 may be shifted to the warming room 6 side, the fitting hole 61 of the tray receiver 22C of the refrigerating room 7 side may be pulled out from the round pin 60, and finally it may be pulled out to the opening side. Then, the entire partition unit 56 may be cleaned by washing with water or the like.
[0031]
In addition, it is possible to remove only the partition unit 56 to which dirt has adhered, and to clean the partition unit 56 only. In this case, the screws 65 of the tray receiver 22H on the side of the storage compartment 6 in the partition unit 56 to be removed are loosened, and the tray receiver 22H is similarly lifted, as shown in FIG. The partitioning unit 56 tilts while the mounted movable member 30 and the stopper member 36 are pushed up, and the fitting hole 68 of the tray receiver 22H comes out above the shaft 67 of the screw 65. The whole 56 may be shifted to the warming room 6 side, the fitting hole 61 of the tray receiver 22C on the cold room 7 side may be pulled out from the round pin 60, and pulled out to the opening side.
Also in the case of assembling after cleaning, the movable unit 30 and the stopper member 36 of the unit partition wall 25 thereon are pushed up to secure the tilting allowable space of the partition unit 56 and can be assembled in the same manner.
[0032]
As described above, according to the present embodiment, when the unit partition wall 25 is supported by the support arms 27H and 27C from both the left and right sides, the reinforcing member 45 is fitted inside the mounting position of the unit partition wall 25, and both the left and right sides are fitted. A structure is adopted in which the mounting portions 43 of the support arms 27H and 27C are fastened together by the reinforcing member 45 and the rivets 50, so that both the support arms 27H and 27C and the unit partition wall 25 can be formed as a single rigid body. . Therefore, the tray receivers 22C and 22H provided at the protruding ends of the support arms 27C and 27H are fitted in the refrigerating chamber 7 only by fitting the round pins 60 into the fitting holes 61. Even with a simple mounting structure in which the screw 67 is simply screwed through the fitting hole 68, the support arms 27H and 27C are tilted so as to form a front V-shape when the load of the tray 20 is received. The unit partition 25 does not go down. Therefore, a gap is formed between the unit partition wall 25 above the unit partition wall 25 and heat insulation is impaired. On the contrary, the movable member 30 is strongly pressed against the unit partition wall 25 below and the tray 20 is inserted. It is possible to avoid adverse effects such as spiciness.
Since it is not necessary to make the structure of the mounting portions of the supporting arms 27H and 27C to the wall surfaces of the warming room 6 and the cold room 7 so strong, the structure is simplified and the weight of the entire body can be reduced. it can. Also, the attachment / detachment work is simplified.
