DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment in which the present invention is applied to a hot and cold serving car will be described below with reference to FIGS.
The hot / cold serving car of the present embodiment is of a pass-through type, and includes a storage room main body 1 (hereinafter simply referred to as a main body) having a rectangular box shape as a whole as shown in FIG. It has a shape with open front and rear surfaces, and is configured as a heat insulating box in which a heat insulating material such as urethane foam is filled in a ceiling wall, a bottom wall, and left and right side walls. A caster (not shown) is provided on the bottom surface of the main body 1 so as to be movable, and a machine room 2 indicated by a chain line is provided on the upper surface.

At the center in the width direction of the front and rear openings of the main body 1, a vertical frame 4 is erected, and an intermediate wall 5 is also provided in the main body 1 at the center in the width direction. The interior is divided into two chambers on the left and right. Further, in the two chambers on the left and right, a heat insulating partition wall 6 described later is provided at the center in the width direction. Thus, two warming rooms 7 are formed outside the partition wall 6 and two cold rooms 8 are formed inside the partition wall 6 with the same width X (see FIG. 5). In other words, two sets of the adjacent storage compartments 7 and 8 of the same frontage are formed in the left-right direction, and these are further divided into front and rear sections, so that a total of four sets of the storage compartments 7 and the refrigerator compartments 8 are formed. The tray 11 is accommodated in multiple stages across the two chambers 7 and 8 in each set of the warming room 7 and the cold room 8. Each set of the preservation room 7 and the refrigerating room 8 is provided with a double door 9 (see FIG. 9).

The tray 11 is formed of a synthetic resin or the like into a horizontally long rectangular shape, and a boundary portion 12 is provided at a position slightly closer to one side than a central portion of the width, and the tray 11 is wide on one side of the boundary portion 12. Of the second mounting portion 14 is narrow on the other side.

Has a width that can be almost fully filled with the warming room 7 or the cold room 8.

[0011] The above-mentioned intermediate wall 5 is provided with a front and rear 2 for cooling air distribution.
The ducts 15 are arranged at intervals, and the left and right surfaces of each duct 15 are divided into a plurality of regions, and a group of vents 16 is formed. Machine room 2
Inside, a cooler room 18 is defined so as to cover both ducts 15 and an opening on a ceiling surface of one of the refrigerator compartments 8, and a cooling unit that forms a refrigeration cycle together with a compressor 19, a condenser 20, and the like therein. A container and a fan in the refrigerator are installed. For this reason, when the refrigeration cycle is operated and the fan in the refrigerator is driven, the cool air generated near the cooler is blown into each duct 15, and is blown out to the left and right refrigeration chambers 8 through the vent group 16. Then, a circulating flow is generated such that the refrigeration room 8 is guided into the cooler room 18 from the ceiling side of the one refrigeration room 8,
Thus, the left and right refrigerating compartments 8 are cooled.

An air filter 21 is provided on the front surface of the condenser 20 of the refrigeration cycle and is appropriately attached and detached for cleaning. However, it is troublesome to remove the top plate of the machine room 2 each time. For this reason, the top plate is provided with a slit 22 so that the top plate can be taken in and out. However, since the air filter 21 is inserted while groping, it is quite difficult to insert the air filter 21 in alignment with the front surface of the condenser 20.

It is attached to the heater panel 30 of the storage room 7, respectively. For this reason, the duct 15 forming the wall surface of the refrigerator compartment 8 is provided with a pair of front and rear support members 52 over a plurality of stages. As shown in FIG. 6, the support 52 has a shape in which a round pin 54 projects from the center of the main body 53.
A pair of front and rear fitting holes 55 into which the round pins 54 can be fitted are formed in the mounting surface 44 of the tray receiver 42C arranged on the refrigerator compartment 8 side.

On the other hand, the heater panel 30 of the storage room 7 also
Similarly, a pair of front and rear support members 57 are provided in a plurality of stages, and as shown in FIG.
And a screw 60 with a head 61 is screwed into it. Similarly, a pair of front and rear fitting holes 62 are formed on the mounting surface 44 of the tray receiver 42 </ b> H disposed on the side of the warming room 7. It is formed in a size that can be hooked on the head 61 and has a fitting hole 6.
At the lower edge of 2, a guide groove 63 that can be inserted into the fitting hole 62 through the shaft of the screw 60 from below is formed to open at the lower edge of the mounting surface 44.

Each partition unit 48 is assembled in order from the lower side, for example. As shown in FIG. 8, the procedure is as follows: the partition unit 48 is placed in the tray receiver 42C on the refrigerator compartment 8 side.
The fitting hole 5 of the mounting surface 44 is
5 is inserted into the round pin 54 of the support tool 52 on the refrigerator compartment 8 side.
Next, when the tray receiver 42H on the side of the storage compartment 7 is set in a horizontal posture so as to be lowered, the shaft portion of the screw 60 of the support member 57 on the storage compartment 7 side is attached to the mounting surface of the tray support 42H on the storage compartment 7 side. 44 enters the fitting hole 62 from below through the introduction groove 63, and the fitting hole 62 is received by the shaft of the screw 60. When the screw 60 is screwed in, the head 61 and the support 5

The unit partitioning wall 36 provided at the uppermost stage is prepared as a single unit without a support arm and a tray receiver, and is attached to the ceiling surface of the main body 1 in a suspended manner, for example.

When all the unit partition walls 36 are assembled, the movable member 37 and the stopper member 38 in each unit partition wall 36 are brought into contact with the upper surface of the unit partition wall 36 therebelow by spring resilience. The movable member 37 and the stopper member 38 of the lower unit partition wall 36 are
Abuts the upper surface of the As a result, a partition wall 6 is constructed to insulate between the paired warming room 7 and cold room 8 in a heat-insulating manner. At the same time, a pair of left and right wide tray receivers 42H and 42C are arranged in a plurality of stages on the wall surface of the pair of the warming room 7 and the cold room 8 opposite to the partition wall 6. . At the bottom, a wide tray receiver 42 that is not unitized is prepared and is directly mounted on the mounting wall surfaces of both chambers 7 and 8.

This embodiment has the structure as described above,
Subsequently, a method of using the same will be described. When serving meals in the serving car, hot and cold meals are separately arranged on the tray 11 and served. In this case, the larger amount is used for the wider first mounting portion 13.
Then, the smaller amount is placed on the narrow second mounting portion 14. When hot food is served on the first mounting portion 13 and cold food is served on the second mounting portion 14, as shown in the first and third stages of FIG. The orientation of the tray 11 is adjusted so that the second mounting portion 14 corresponds to the refrigerator compartment 8 in the chamber 7, and the tray 11 is pushed in such a manner that the boundary portion 12 contacts the movable member 37 mounted on the unit partition wall 36. Then, the movable member 37
Is lifted up against the spring elasticity, the boundary portion 12 is broken between the movable member 37 and the upper surface of the unit partition wall 36 thereunder, and both side edges of the tray 11 are moved from the guide portion 45 to the tray receiver 42H. , 42C, slides on the receiving surface 43 of the tray 11, is pushed in while sliding, and the back end of the tray 11 hits the stopper member 38, thereby completing the storage.

At this time, since the receiving surfaces 43 of the tray receivers 42H and 42C are formed wide, the side edges of the second mounting portion 14 having a small width also have the receiving surface 43 of the tray receiver 42C on the refrigerator compartment 8 side. And the tray 11 can be smoothly inserted, and is stably supported even after the storage is completed.
Further, although the side edge of the second mounting portion 14 is largely separated from the duct 15, the tray is closed by the tray receiver 42H, so that the cool air blown out of the duct 15 flows downward from the gap. Escape is suppressed, and the second mounting portion 14
Since it is directed to the upper cold food, the cold food can be cooled well. In addition, since the through-hole 50 is opened in the support arm 40C of the refrigerator compartment 8 side, the cool air which does not flow on the tray 11 can flow downward through the through-hole 50, and the cool air is effectively used. You.

On the other hand, when the amount of the cold meal is larger than that of the hot meal, the cold meal is served on the wide first mounting portion 13 of the tray 11 and the hot meal is served on the second mounting portion 14. In this case, as shown in the second row of FIG.
Then, the orientation of the tray 11 is adjusted so that the second mounting portion 14 corresponds to the warming room 7, and the boundary portion 12 is similarly set to the unit partition wall 36.
And is pushed into the movable member 37 attached thereto.

At this time, the tray receivers 42H, 42
Since the receiving surface 43 of C is formed to be wide, the side edge of the second mounting portion 14 having a small width is also used for the tray receiver 4 on the side of the warming room 7.
The tray 11 is received by the receiving surface 43 of 2H, and similarly, the tray 11 can be smoothly inserted, and is stably supported even after the storage is completed. Further, although the side edge of the second mounting portion 14 is largely separated from the heater panel 30, the second mounting portion 14 is closed by the tray receiver 42 </ b> H.
The radiant heat from is prevented from escaping upward from the gap and directed to the hot meal on the second mounting portion 14, so that the hot meal can be satisfactorily heated.

When the tray 11 is to be taken out, the tray 11 may be pulled out in the direction opposite to the direction in which it is inserted. In addition, the serving car of the present embodiment can be used in a so-called pass-through mode in which the tray 11 accommodated from the front side is taken out from the rear side, or vice versa. For example, tray 1 from the front side
1, the push-in is once restricted by the stopper member 38, but when the push-in is further pushed in, the boundary portion 12 is pressed against the stopper member 38 and cracks into it while lifting it against the elasticity of the spring. Can be moved to the side.

As described above, according to the present embodiment,
In the case where the frontage dimension X between the warming room 7 and the cold room 8 is the same, and the receiving surfaces 43 of the tray receivers 42H and 42C arranged on both sides are formed wide, so that the ratio of the amount of the hot food and the amount of the cold food is different. If the larger amount is put on the first mounting portion 13 of the tray 11 and the orientation of the tray 11 is adjusted so that the hot food and the cold food correspond to the hot room 7 and the cold room 8, respectively, Each can be stored well or chilled.

In this case, in the warming room 7 or the refrigerating room 8 in which the second mounting portion 14 is placed, the side edge of the second mounting portion 14 is largely separated from the heater panel 30 or the duct 15. However, since the tray receivers 42H and 42C are formed wide, the side edges on the second mounting portion 14 side are also received, and the tray 11 is stably supported. Further, since the space between the side edge of the second mounting portion 14 and the heater panel 30 or the duct 15 is closed by the tray receiver 42H or 42C, warm air or cold air flows between the side edge of the second mounting portion 14 and the heater panel 3.
0 or the duct 15 is prevented as much as possible, the hot or cold food served on the second mounting portion 14 is reliably applied, and it is possible to store or refrigerate well.

Further, since the tray receiver itself is made of stainless steel plate, the temperature of the tray receiver 42H disposed on the side of the refrigerator compartment 7 becomes high and the temperature of the tray receiver 42C disposed on the side of the refrigerator compartment 8 becomes low. Since the surface of the receiving surface 43 is coated with a resin, a change in temperature on the surface can be suppressed to a small value. In addition, since the opening 49 is formed in the receiving surface 43, the resin coated on the opening 49 is caught and the resin coated on the surface is prevented from peeling or expanding due to thermal expansion or the like. You.

<Modification> As shown in FIG. 9, when arranging the tray receiver 42C on the refrigerator compartment 8 side, the mounting surface 44 of the tray receiver 42C is arranged so as to be separated from the duct 15 to such an extent that it can be accessed. By doing so, the surface of the duct 15 can be easily cleaned. Of course, even in the storage room 7, the tray receiver 4
If the 2H mounting surface 44 is arranged so as to be accessible to the hand from the surface of the heater panel 30, the surface of the heater panel 30 can be easily cleaned similarly. Further, as shown in the figure, if a through hole 50 is opened in the center of the receiving surface 43 of the tray receiver 42C arranged on the refrigerator compartment 8 side in the same manner as the support arm 40C, the tray 11 Cold air that does not flow can flow downward through the through holes 50, and the cool air can be used more effectively.

<Other Embodiments> The present invention is not limited to the embodiments described above with reference to the drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition, various changes can be made without departing from the scope of the invention. (1) In the above embodiment, the pass-through type serving truck is illustrated, but the present invention is similarly applicable to a standard type serving truck in which the tray can be pulled out only in the insertion direction. (2) The present invention can be widely applied to general warming / cooling apparatuses in which a warming room and a cold room are provided on both sides of a partition wall.
