である。 Conventionally, this type of refrigerator had a compression-condensing unit arranged on the outside surface of the storage body, and a cooling unit such as an evaporator connected to the compressor and condenser of that unit was arranged on the inside surface of the storage body. is known, but since it is configured to cool from the side, there is a problem in terms of cooling efficiency. Therefore, some devices have installed a cooling unit in the upper part of the storage interior to improve cooling efficiency, but since the cooling unit is supported in a cantilevered manner, the unit support part may be damaged by vibrations caused by the vehicle. There is a risk of damage, and it is troublesome to have to remove the cooling unit when taking things in and out.

的とする。 In view of the above, the present invention aims to improve cooling efficiency by providing a secondary refrigerant chamber with a cooling function in the lid that opens and closes the entrance/exit on the top surface of the storage body, and also makes it easier to take things in and out. The evaporator for cooling the refrigerant in the secondary refrigerant chamber connected to the secondary refrigerant chamber also serves as the rotation shaft of the lid, thereby reducing the space occupied by the lid and allowing smooth opening and closing of the lid. It is an object of the present invention to provide the above-mentioned refrigerator in which the durability of the heat exchange joint between the refrigerator and the evaporator can be improved.

The inside of the side wall and bottom wall is filled with a heat insulating material U1 such as urethane foam. A compression-condensation unit 5 equipped with a compressor 3 and a condenser 4 is detachably provided on the outer surface of the storage body 1. In the illustrated example, the attachment/detachment structure is the compression-condensation unit 5.
The unit 5 is positioned by engaging the lower surface of a pair of evaporator support portions 7 protruding from the upper side of the housing 6 with the upper surface of the storage body 1. The retaining rings 8 are releasably engaged with respective pairs of retaining metal fittings 9 provided on both outer surfaces of the storage body 1. When the unit 5 is configured to be detachable from the storage body 1 in this manner, only the storage body 1 can be carried, which is convenient as it can be used as an ice cooler for fishing or the like. Of course, in this case, use another lid body instead of storage body 1.

けた係止環および係止金具である。 The inside of the lid body 14 which opens and closes the entrance/exit 2 is filled with a heat insulating material U 2 such as urethane foam, and a case 15 covering the entrance/exit 2 of the storage body 1 is fixed to its concave inner surface. A refrigerant R such as Freon is sealed in the box 15 to constitute a secondary refrigerant chamber 16 . On one side of the secondary refrigerant chamber 16, numerous fins 17 are formed on the outer peripheral surface between the opposing walls of the box 15 and the lid 14.
A heat conduction tube 18 having a shape is fixed. Lid body 14
is rotatably attached to the cylindrical evaporator 10 by closely fitting its heat conductive cylinder 18 to the outer peripheral surface of the heat conductive cylinder 11 of the cylindrical evaporator 10. Both conduction tubes 1
A lubricant such as silicone grease or grease mixed with fine metal powder is interposed on the outer and inner circumferential surfaces of the cylinders 1 and 18 to improve heat conduction between the cylinders 18 and 11 and to prevent the lid 14 from opening and closing. Make it happen smoothly.
Further, a plurality of fins 19 having a U-shaped cross section are provided on the outer surface of the secondary refrigerant chamber 16. In addition, 20 and 21 in the figure are a locking ring and a locking metal fitting provided on the storage body 1 and the lid body 14, respectively.

再び気化→凝縮→液化の状態変化が繰返される。 During refrigeration, the heat inside the storage body 1 is propagated to the liquid refrigerant through the fins 19, so the refrigerant R is evaporated and vaporized, and the heat inside the storage body 1 is taken away during this vaporization, so that the inside of the storage body 1 is cooled. The vaporized refrigerant R is cooled by the cylindrical evaporator 10 and is condensed and liquefied,
The state change of vaporization → condensation → liquefaction is repeated again.

とがない。 As described above, according to the present invention, there are two entrances and exits on the top surface.
A compression-condensation unit 5 is installed on the outer surface of the storage body 1 having a
A cylindrical evaporator 10 connected to the compressor 3 and condenser 4 of this unit 5 is provided on the upper surface of the storage body 1, and a lid 14 for opening and closing the inlet/outlet 2 of the cylindrical evaporator 10 is rotatable. A secondary refrigerant chamber 16 is formed that accommodates the cylindrical evaporator 10 in the lid body 14 and covers the entrance/exit port 2.
Since the cool air is enclosed in the storage body 1 from the upper part, the cooling efficiency can be improved, and when the lid body 14 is opened, the secondary refrigerant chamber 16 with a cooling function is opened together with the lid body 14 at the entrance/exit. Since it is removed from 2, it is easy to take things in and out. Furthermore, the cylindrical evaporator 10
Since the cylindrical evaporator 10 and the rotating shaft are also used as the rotating shaft of the lid 14, the space occupied by the cylindrical evaporator 10 and the rotating shaft is reduced compared to when they are provided separately, contributing to miniaturization of the refrigerator. Since the heat exchange joint between the secondary refrigerant chamber 16 and the cylindrical evaporator 10 for cooling the refrigerant does not interfere with the opening and closing of the lid 14, the lid 1
4 can be opened and closed smoothly, and the durability of the heat exchange joint is also improved. Furthermore, since the secondary refrigerant chamber 16 is integrated with the lid 14,
It will not be damaged by vibrations etc. while the car is running.
