Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a mounting device for mounting a refrigeration device to the top wall of a heat-insulating box such as a refrigerator.

(b) Prior art Generally, when a refrigeration system consisting of a refrigerant compressor, a condenser, a cooler, etc. is installed in a large insulated box such as a commercial refrigerator or a prefabricated refrigerator, the refrigeration system is installed in a box-like or plate-like form made of insulating material. A method is used in which the refrigeration equipment is attached to a shaped support to form a unit, and the unitized refrigeration equipment is attached to the side wall or top wall of the heat insulating box. By unitizing the refrigeration equipment in this way, the insulation box and the refrigeration equipment can be manufactured in separate processes, which simplifies the manufacturing work of the insulation box and the piping connection work for the refrigeration equipment. This has the advantage that the installation of the refrigeration system is extremely simple.

However, as a device for attaching a unitized refrigeration system to the top wall of an insulated box,
As shown in Publication No. 42443 and Publication No. 58-13267, two pairs of fixtures are fixed to the left and right side walls and the top wall of the support body, and these two pairs of fixtures are connected by nuts. Four rod-shaped connectors were used.

According to such a mounting device, after the lower ends of the connectors are inserted and engaged with the fixtures on the ceiling wall, the upper ends of the connectors are passed through the fixtures on the support, and each connector is tightened with a nut. The refrigeration system can be attached to the ceiling wall of the insulated box by pressing it toward the ceiling wall.

However, such a mounting device not only requires four fixtures to be fixed to the support and the ceiling wall, but also connects these fixtures with four connectors, so it is simply a matter of connecting the parts. Not only will you get more points, but
It takes a lot of time to install it, and since the connector is rod-shaped, if the vertical position of the fixture on the support body and the fixture on the ceiling wall do not match, the connection work will be troublesome due to the connector, and you will only have to do the installation work. In addition, there was a disadvantage that labor costs were incurred for removal work associated with maintenance and inspection of the refrigeration equipment.

Also, on the cooling unit side of the refrigeration device 7, when the interior 5 of the cooling unit is temporarily installed, the cooler 14, drain pan 18, etc. are installed on the ceiling wall 4.
In addition, after installation, the refrigeration system 7 is protected from the impact caused by taking out and taking out the stored items in the refrigerator 5, and as shown in FIG.
Before installation, a plurality of U-shaped metal guard legs 20 are provided to protect the cooler 14, drain pan 16, etc. from the floor.

As shown in FIGS. 4 and 5, the support body includes an upper plate 21 made of a metal plate and a lower plate 2 made of a resin plate.
2, and the foam insulation material 2 filled between the upper and lower plates.
3, and a frame member 24, such as wood, in the shape of an opening, which is interposed between the upper and lower plates 21, 22 and surrounds the foam insulation material 23.
It is composed of. 25, 25 is the support body 8
A pair of handles formed by inwardly recessing the parallel sides of the frame member 24, that is, the two opposing parallel sides of the frame member 24, are used when transporting the refrigeration device 7 and when storing the refrigeration device in an insulating box. It is used when placed on the ceiling wall 4 of the body 1. Reference numerals 26 and 26 denote a pair of holding members made of metal plates, which are opposed to the ceiling wall 4 and have a base 29 formed with a through hole 28 at an appropriate location to face the screw hole 27 of the ceiling wall, and a support member. an upright part 3 that faces in close proximity to or abuts against the circumferential surface of 8 and has a fitting part 30 formed thereon that faces inward and is fitted into the handle;
