DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator mounted on a ship, and more particularly to a refrigerator for a ship provided with a prefabricated refrigerator.

[0002]

In recent years, installation of a refrigerator in a cabin is often performed after a hull is completed due to demands for efficiency and labor saving. That is, a marine refrigerator is manufactured by carrying a heat insulating panel having a structure in which a polyurethane resin is sandwiched between PVC steel plates into a cabin and assembling it into a box shape.

By the way, the floor of the cabin where the refrigerator is installed is inclined in order to improve drainage, but the shelves and hook rails inside the refrigerator must be horizontal. For this reason, conventionally, the shape of the refrigerator is adjusted to the inclination of the floor by using, for example, a heat insulating panel that is obliquely cut in accordance with the inclination on the floor side of the cabin. However, in the construction method using the cut heat insulation panel, the joint mechanism cannot be used for joining the corner portions along the inclination direction of the floor. Further, in a corner portion along a direction orthogonal to the inclination direction of the floor, the heat insulating panels intersect at an acute angle or an obtuse angle, so that the joint mechanism cannot be used. Since it is difficult to join the heat insulating panels with high airtightness and watertightness without using a joint mechanism, installing the refrigerator in the cabin requires a great deal of time and effort.

Further, when the heat insulating panel is directly mounted on the wall surface of the cabin, the heat insulating panel cannot be mounted unless the welding process on the wall surface of the adjacent room is completed, so that the work efficiency is poor. Therefore, an object of the present invention is to make it possible to easily install a refrigerator in a cabin. In particular, it is an object of the present invention to allow the heat insulating panels constituting the refrigerator to be joined to each other by using a joint mechanism on an end face thereof.

[0005]

Means for Solving the Problems The object of the present invention, the end

Solved by refrigeration equipment .

[0006]

In the present invention, the placing surface of the refrigerator is not limited to the one actually constituted by the surface material, but also the virtual surface determined by the portion (supporting point or supporting line) abutting on the refrigerator. Including. That is, the ship of the present invention
The refrigeration system installed on the ship is provided with a gantry configured to correspond to the inclination of the floor of the cabin so that the mounting surface of the refrigerator is horizontal, and the refrigerator is installed in the cab through this gantry. Therefore, it is not necessary to make the shape of the refrigerator special to match the inclination of the floor. In particular, there is no need to use an insulated panel that has been subjected to processing such as diagonal cutting as the insulated panel located on the floor side of the cabin, and the insulated panel can be used in its original shape. Further, there is no portion where the heat insulating panels intersect or join at an acute angle or an obtuse angle. Therefore, all the heat insulating panels can be joined by using the joint mechanism provided on the end face, and the labor required for manufacturing the refrigerator portion can be greatly reduced. As a result, even if the labor required for assembling the gantry is taken into consideration, the required labor as a whole is significantly reduced as compared with the related art, and the apparatus itself can be easily installed.

[0008] The refrigeration system installed on the ship is
A gap between the wall of the cabin and the side of the refrigerator
Preferably, This enables welding work on the adjacent room wall
Production of refrigerators at the same time
Work efficiency is improved.

Further, in order to prevent the vibration of the boat from being transmitted to the refrigerator as much as possible, it is preferable that a cushioning material is provided on the mounting surface of the refrigerator in the frame. Further, in order to prevent the refrigerator from dropping off the gantry, it is preferable that the gantry is provided with a guide piece which abuts against the side surface of the refrigerator to prevent a displacement. Further, in order to prevent damage to the side surface of the refrigerator, it is preferable that a cushioning material is provided on a surface of the guide piece that is in contact with the side surface of the refrigerator.

[0010] The base end of the support beam is fixed to the cabin wall.
The fixed piece and one end contact the top of the refrigerator.
And a movable piece whose other end is connected to the fixed piece,
It is possible to change the connection position between the fixed piece and the movable piece.
Can be configured.

[0011] Further, it is preferable that the heat insulating panel constituting the ceiling of the refrigerator is provided with a suspending tool used for suspending articles. That is, the conventional hanging device is fixed to the ceiling of the cabin, and through a through hole formed in the heat insulating panel,
A shaft for suspending the article is projected into the refrigerator, and an operation for closing the gap of the through hole is required. However, if the suspenders are provided directly on the heat insulating panel, the through holes become unnecessary, and the work of closing the gap can be omitted, so that the efficiency can be further improved.

[0012] In particular, the hanging device has at least a part of an anchor embedded in a heat-insulating panel constituting a ceiling, and one end joined to the anchor and the other end protruding into a refrigerator. Can be provided. Further, it is preferable that a drainage tool is provided integrally with the heat insulating panel on the heat insulating panel constituting the floor of the refrigerator. That is, conventionally, a large through-hole for allowing a dimensional error is formed in a heat insulating panel constituting a floor of a refrigerator, and a drainage tool is attached to the through-hole at the time of assembling the refrigerator. For this reason, the work which closes the space | gap of a through-hole like the case of the hanging tool was needed. However, by providing the drainage tool integrally with the heat insulating panel, the trouble of closing the through hole can be omitted, and the work efficiency can be further improved.

In particular, the drainage tool has a drainage pipe detachable from the main body thereof, and the length of the drainage pipe protruding from the bottom of the refrigerator is determined by the length of the refrigerator at the position where the drainage tool is provided. It is preferable that the distance be larger than the distance between the bottom surface and the floor of the cabin. As a result, the drainage can be reliably guided into the drainage hole provided in the cabin floor, and the drainage can be prevented from scattering on the cabin floor.

As shown in FIG. 6, the gantry B is composed of a frame 9 formed by welding angle members by welding, and legs 10 made of angle members which are also attached to predetermined positions of the frame member 9 by welding. Is done. As can be seen from FIG. 1 and the like, the length of the legs 10 changes stepwise according to the inclination of the floor of the cabin, so that the surface on which the refrigerator A is mounted (virtual mounting surface) is horizontal. It has become. The cabin floor may be inclined not only in one direction but also in two directions. In this case, the length of the leg 10 may be changed stepwise along both the vertical and horizontal directions of the frame body 9, which can be handled in the same manner as in the case of one direction. In addition, even when there is a step on the floor of the cabin, it can be dealt with by changing the length of the leg 10 accordingly.

On the outer peripheral portion of the frame 9 of the gantry B, guide pieces 11 abutting on the front, rear, left and right side surfaces of the placed refrigerator A.
Are provided, and the guide piece 11 allows the refrigerator A
To prevent falling off. The guide piece 11 is attached to the frame 9 as shown in FIG. That is, a small angle member 12 is partially welded to the back surface of the angle member 9 a constituting the outer peripheral portion of the frame body 9.
The nut 13 is welded to the through-hole portion formed in 2. The guide piece 11 has a bolt hole formed at the lower end thereof, and a rubber sheet (cushion material) 14 for damage prevention attached to the side facing the refrigerator A is sandwiched between the guide piece 11 and the angle material 12.

As can be seen from FIGS. 9 and 10, the support beam 17 has a fixing piece 18 whose base end is fixed to the cabin wall surface, one end of which abuts on the upper end of the refrigerator A, and
The other end comprises a movable piece 19 connected to the fixed piece 18.
A long hole 18a is formed in the fixed piece 18 and a bolt hole is formed in the movable piece 19, and the connection position between the fixed piece 18 and the movable piece 19 is changed so that the support beam 17 can be adjusted to an appropriate length. Is possible. After the connection position is determined, the movable piece 19 is fastened to the fixed piece 18 by bolting. Note that the distal end of the support beam 17 is not fixed to the refrigerator A, and is in a state of being pressure-bonded via a rubber sheet (buffer) 20. This is to prevent the vibration of the ship from being transmitted to the refrigerator A as much as possible.

The heat insulating panel 4 constituting the ceiling of the refrigerator A is provided with a hanging member 21 as shown in FIG. The hanging member 21 includes an anchor 22 having a dish-shaped cross section embedded in the heat insulating panel 4, and a shaft 24 screwed to a nut 23 welded to a through hole of the anchor 22. The article is suspended from the heat insulating panel 4 using the shaft 24. For example, the cooler 2 is suspended from the heat insulating panel 4 at appropriate intervals by sandwiching a wooden spacer 25.

The hanger 21 is also used for attaching a hook rail 26 as shown in FIG. Through holes are formed in the hook rail 26 at the same interval as the shaft 24,
The hook rail 26 is attached to the heat insulating panel 4 constituting the ceiling by protruding the shaft 24 from the through hole and tightening the nut from above and below. The hook rail 26 is formed by forming notches 26a at predetermined intervals in an angle material, and an S-shaped hook 27 is engaged with the notches 26a.

The anchor 22 need not necessarily be embedded in the heat insulating panel 4. For example, it may be provided outside the refrigerator while being placed on the heat insulating panel 4. In this case, the shaft 24 has a structure that penetrates the heat insulating panel 4 and is screwed to the anchor 22. The heat insulation panel 4 constituting the floor of the refrigerator A is provided with the drainage tool 3 integrally therewith.
FIG. 13 shows a cross section of a portion where the drainage tool 3 is provided.

In addition, a drainage pipe provided on the floor of the cabin has a drainage pipe 31.
A pipe 32 having a diameter about twice as large as the pipe 32 is provided upright, and the drain pipe 31 is inserted into the pipe 32. The reason why the diameter of the pipe 32 is made larger than that of the drain pipe 31 is to allow an error in the mounting position of the drainage tool 3.

Reference numeral 33 denotes a lid, 34 denotes a gasket, and the lid 3
A pin 33a for preventing misalignment provided at a 120 ° interval on the back surface of the main body 3 penetrates the hole formed at the same interval in the gasket, and protrudes between the outer cylinder of the main body 28 and the siphon cover 29. I have. The above-described refrigerator installed in the ship of the present invention includes a gantry B configured to correspond to the inclination of the floor of the cabin so that the mounting surface of the refrigerator A is horizontal, Refrigerator A is installed in the cabin via this base B. Therefore, it is not necessary to make the shape of the refrigerator A special. In particular, there is no need to diagonally cut the heat insulating panel 4 located on the bottom side of the refrigerator A. Moreover, since there is no portion where the heat insulating panels 4 intersect at an acute angle or an obtuse angle, all the heat insulating panels can be joined using the joint mechanism provided on the end face. Therefore, the labor required for manufacturing the refrigerator part can be greatly reduced, and even if the labor required for assembling the gantry B is slightly increased, the required labor as a whole is significantly reduced as compared with the conventional technology, and the installation in the cabin is reduced. It will be easy to do.

By embedding the hanging members 21 in the heat insulating panel 4, the following effects can be obtained.
That is, conventionally, a suspender for suspending the cooler 2, the hook rail 26, and the like is fixed to the ceiling of the cabin, and a heat insulating panel forming the ceiling is formed with a through hole for inserting a shaft of the suspender. Had to be kept. However, finally, the gap of the through-hole must be closed, which is troublesome. On the other hand, in the present invention, since the hanging member 21, especially the anchor 22, is directly embedded in the heat insulating panel 4, it is not necessary to form a through hole. Therefore, the trouble of closing the gap can be omitted, and the efficiency can be further improved.

Also, regarding the drainage tool, conventionally, a considerably large through hole is formed in the heat insulating panel constituting the floor in consideration of an error, and after attaching the through hole, the void is filled with polyurethane resin. It was provided in a time-consuming manner. However, if the drainage tool 3 is embedded in the heat insulating panel 4 in advance as in the present invention, the work of closing the gap can be omitted, and further labor saving can be achieved.

The drainage pipe 31 of the drainage tool 3 has a long end whose lower end is located below the floor of the cabin, and the pipe 32 surrounding the drainage pipe 31 is provided. Even if the drainage gushes well, it does not splash into the cabin. By the way, it was examined how much a difference in the work time required for the installation of the refrigerator between the case where the gantry is used and the case where the gantry is not used. The result is shown below. However, the number of heat insulating panels used is the same for both, and is 50 to 70. [When using a gantry] Time required to assemble the gantry: 20 to 30 hours Time required to manufacture the refrigerator: 100 to 140 hours Time required to fix the refrigerator: 100 to 140 hours [When not using the gantry] The time required for manufacturing the refrigerator: 250 to 350 hours The time required for fixing the refrigerator: 150 to 210 hours From these results, the technology of the present invention requires less work time for manufacturing and fixing the refrigerator than the conventional technology. Although it is extremely short and requires some time to assemble the gantry, it can be seen that the working time as a whole can be greatly reduced and the working efficiency is excellent.

[0029]

The refrigerator can be easily installed in the cabin.
In particular, all the heat insulating panels constituting the refrigerator can be joined using the joint mechanism on the end face thereof, so that the labor required for manufacturing the refrigerator part can be greatly reduced.
