Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a cold/hot storage that is mounted on a motor vehicle such as a one-box car.

(Prior Art) Vehicles such as one-box cars that can accommodate six to eight people are equipped with a refrigerator to cool drinks, coffee, and the like. For example, the refrigerated/heated refrigerator for automobiles described in Japanese Patent Application Laid-Open No. 1967-1987 is
The evaporator is bent in a serpentine shape and placed inside the refrigerating room.

(Problems to be Solved by the Invention) Therefore, the evaporator protrudes and crushes the volume of the refrigerated/green room, thereby impairing the storage capacity of articles.

Therefore, the purpose of this invention is to prevent the volume of the cold storage compartment of a cold storage from being reduced by a refrigerating element such as an evaporator.

(Means for Solving the Problems) Therefore, the gist of this invention is that a storage case 17 forming a cold/warm storage compartment 11, a storage case 17, and a partition wall 10 disposed in parallel with the storage case 17 define the storage case 17 and the storage case 17, A heat insulating resin wall 8 surrounding the blower room 12

7.

(Function) Therefore, the evaporator 26
The evaporator 26 is arranged along the wall surface 8 of the
The fins 30 are also located on the wall side, which is the back surface, and the ventilation passages 40 are also located on the side and bottom surfaces of the evaporator 26, so that they do not protrude into the cold storage compartment 11, and the reduction in volume can be suppressed as much as possible.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a vehicle body called a one-box car. Warehouse 4 is arranged.

This cold/hot storage 4 is located along the side wall 5 of the vehicle body 1.
Moreover, a part of the cold/hot storage 4 is buried in the side wall 5 through a notch 5a' formed by cutting out an inner plate 5a constituting the side wall 5.

The cold/hot storage 4 is shown in FIGS. 2 to 4, and is molded from synthetic resin such as plastic, and has a double wall structure having two resin walls 7, 8. Although not shown, a heat insulating material is inserted between the holes.

In this way, the double-structured resin walls 7 and 8 form a partition wall 1 in the vertical direction at a position in one-third of the space of the structure.
0 is formed, and on the right side of this partition wall 10 is a cold storage room 11, and on the left side is formed a blower room 12 in which a blower, an expansion valve, etc. are housed.

The cold storage compartment 11 has an upper lid 13 for opening and closing above it.
is provided, but the upper lid 13 is one-third from the back side.
It is rotatably connected to a top plate 14 fixed to the upper ends of the resin walls 7, 8 by a hinge 18. In addition, this cold/warm room 11 is also provided with a side lid 15 that opens and closes using its lower end as a fulcrum on its front side, and inside (on the back side) of the side lid 15 there is provided a case 17 for storing items to be cooled or heated as described below. is installed.

The side lid 15 has an opening 16 at the front of the cold storage compartment 11.
However, the lower end 17a of the storage case 17 attached to the back surface of the side lid 15 is arranged inside the lower edge 16a of the opening 16, and the lower edge 16a of the opening 16 is connected to the lower edge 16a of the opening 16 by a hinge (not shown) at that part. is combined with

The storage case 17 is made of resin and has a box shape, has an open top surface, and has a stepped portion 20 in the middle on which the partition plate 19 is placed. There is a hole 22 aligned with the blow-off hole 21 formed on the side, and a hole 23 on the right side and the bottom.
24 are formed in two rows along each end. When the side lid 15 is opened forward, the storage case 17 rotates about its lower end, and its upper surface is pulled out to the outside.

The evaporator 26 serves as a cooling means,
The cold storage chamber 11 is composed of a flat tube.
pipes 27 and 28 forming a refrigeration cycle (not shown) are connected to both ends thereof, and refrigerant is sent from a compressor and a condenser (not shown). It is supplied via an expansion valve 29.

Corrugate-shaped fins 30, 30 are welded and attached to the lower surface of the evaporator 26, and these fins 30, 30 are provided in two rows along the longitudinal direction of the evaporator, and are located in the center. The fins 30, 30 are in contact with a wall 8, and a space 31 is formed between the fins 30, 30 and the wall 8. Further, since the width of the evaporator 26 is considerably shorter than the width in the lateral direction of the cold storage 12 described above, the evaporator 26
Elongated spaces 34, 34 are formed along both sides of the fins 30, 30, and these spaces 34, 34 communicate with the storage case 17 through the holes 23, 24, and the elongated spaces 34 ,34
is connected to the space 31 via the fins 30, 30, and the space 31 and the spaces 34, 3
4 constitute a ventilation passage 40. 33 is a lining made of foamed resin or the like provided between the evaporator 26 and the storage case 17.

The space 31 communicates with a hole 32 formed in the partition wall 10 described above at the left end, and the passage 31 communicates into the blower chamber 12 . Note that the inner resin wall 8 constituting the space 31 is recessed to expand the cross-sectional area of the space 31, and to improve drainage of condensed water.
The bottom surface 8a is an inclined surface, and a drain hole 9 is provided at the lowest point.

A blower 35 is housed in the blower chamber 12, which sucks air from an inlet and blows it out from an outlet 36.
It is supplied into the cold storage compartment 11 through the hole 21 of the partition wall 10 and the hole 22 of the storage case 17.

The air outlet 36 of the blower 35 is provided with an electric heater 37 which is a heating means for turning air into hot air, and the electric heater 37 heats the air to turn it into warm air.

In the above configuration, when used as a refrigerator, the compressor is rotated to supply refrigerant to the evaporator 26, and the blower 35 is also rotated. As the blower 35 rotates, air is sucked in from the suction port and blown out from the air outlet 36.
It is blown out into the cold storage room 11 through 22. The blown air is circulated through the holes 23, 24, the elongated spaces 34, 34 which are the ventilation passages 40, passes through the fins 30, 30 of the evaporator 26, and is cooled, and is then cooled from the space 31, which is also the ventilation passage 40. The air flows through the air blower 32 into the blower chamber 12 again, is sucked in by the air blower 35, and is circulated again as described above.
Therefore, the temperature in the cold/warm storage compartment 11 is lowered by the circulation of air, and the articles in the storage case 17 are cooled.

Furthermore, in order to warm the article, the supply of refrigerant to the evaporator 26 is of course stopped and the heater 37 is energized. The blown air is then heated and can therefore be warmed.

In this embodiment, there is one space 31 along the evaporator 26, but three fins 30 are arranged side by side with an appropriate gap to form two spaces 31.
1 can also be formed.

(Effects of the invention) As described above, according to this invention, the evaporator is arranged along the wall of the cold storage room, and the fins for expanding the cooling area are on the back side. It is possible to suppress this decrease in volume as much as possible without protruding.
