Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator for storing fresh foods, medicines and the like which need to be kept cool and transported by a truck or other transport vehicle.

[0002]

2. Description of the Related Art Conventionally, when delivering goods such as perishable food products that need to be kept cold, the goods from the client are temporarily collected at a collection place, mounted on a transport vehicle from this collection place, and cooled by the recipient. A physical distribution system for delivering the goods to the transportation vehicle has been established, and when this article is mounted on the transportation vehicle, it is stored in a cold storage box in advance and the cold storage box is loaded on the transportation vehicle.

As a cooling structure for such a cool box, for example, one disclosed in Japanese Patent Laid-Open No. 5-296642 is known.

This cool box has a machine room in which an evaporator and a cold storage agent are installed inside the cool box body, while a compressor, a condenser, a fan unit for the condenser, etc. are installed on the ceiling of the cool box body. It is provided. The condenser fan unit is driven to forcibly cool the condenser with the outside air, and the heat of vaporization of the evaporator is used to store the regenerator to keep the inside of the refrigerating box body cool.

[0005]

By the way, conventionally, when the condenser and the compressor are installed in the machine room, the condenser is lifted to the windward side of the machine room (on the ceiling in front of the cool box body). Place, then lift the compressor and place on the lee side of the condenser. These devices are then screwed to the ceiling, after which the condenser and compressor are connected to each other by welding refrigerant pipes. This completes the work of installing the condenser and the compressor.

However, in the welding operation of this refrigerant pipe, there are many problems such as the parts constituting the refrigeration circuit being an obstacle to the welding being difficult, and heating other than the welded portion causing thermal deformation.

[0007] Further, in order to make the entrance of articles on the front side of the cool box body large, when the front ceiling of the cool box body is designed to be higher than the rear ceiling, the condenser is arranged at this high position. On the other hand, install the compressor in a low position. In this way, since the condenser and the compressor are located at different heights, attempting to mount refrigeration circuit components on a single unit stand as in the past would complicate the shape of the unit stand and also reduce the weight. It becomes bulky and even expensive.

In view of the above-mentioned conventional problems, the object of the present invention is to integrally connect a condenser and a unit stand on which a compressor and the like are installed by a connecting frame, thereby making it possible to install the refrigerator in a very simple manner. It is to provide a method for installing a cooling device.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the invention of claim 1 is such that the front ceiling of the cool box body is formed to be high and the rear ceiling is formed to be low, and the top of the front ceiling is formed. A condenser, which is a component of the cooling device, is installed on the rear ceiling, and a unit stand is also installed on the rear ceiling, which is also a component of the cooling device. In a cool box in which pipes are welded and connected, a structure is provided that has a connecting frame in which the condenser and the unit base are integrally connected. According to a second aspect of the present invention, in the method of installing the cooling device for the cold storage of the first aspect, the condenser and the unit base are integrally connected by a connecting frame corresponding to the installation height of the ceiling, and then, The condenser and the compressor are connected by welding a refrigerant pipe, and thereafter, the integrated condenser and unit stand are mounted and fixed on the ceiling.

According to these inventions, the refrigerant pipe can be welded before the condenser and the compressor are placed on the ceiling, and the condenser and the compressor can be connected, so that the welding work is simplified.
