Description

[Detailed description of the invention] This invention relates to a refrigeration system that integrates both cooling and condensing units and places the cooling unit inside the refrigerator. Its purpose is to immobilize the body and support the cooling unit.

First, a conventional example will be described with reference to FIGS. 1 to 3. A is a relatively large sectional refrigerator, and a top wall B serving as one side wall is formed with an opening C that communicates the inside and outside of the refrigerator. Reference numeral 1 denotes a refrigeration system that integrates both cooling and condensing units, in which a refrigerant compressor 2, an air-cooled plate fin condenser 3, and an axial blower 4, which constitute the condensing unit, are mounted and supported on the outside surface of the refrigerator. An outer body 5 made of a metal plate that covers the outer surface of the opening C by bringing the flange 5a formed on the peripheral edge into contact with the outer side surface of the ceiling wall B.
The outer body 5 includes an elastic and water-resistant heat insulating plate 6 such as polystyrene foam placed on the inner side of the refrigerator and interposed in the opening C, and a flange 7a formed on the peripheral edge.
The inner side of the heat insulating plate 6 is covered with the outer body 5 together with the heat insulating plate 6 with bolts 8 and nuts 9, and an air-cooled plate fin cooler 10, axial flow type An inner body 7 made of a metal plate that suspends and supports a cooling unit consisting of a blower 11, a cooler, and a case 12 that houses the blower, and a mounting portion 14a that is fixed to the inner body 7 with a fastener 13 such as a screw or screw. and two guards 14, 14 made of two U-shaped metal bar members each having a protective portion 14b surrounding the cooling unit. When the refrigeration device 1 is placed in the refrigerator A, the guard prevents the items stored in the refrigerator from coming into contact with the cooling unit, and before the refrigeration device 1 is placed in the refrigerator A, it acts as an installation foot for the refrigeration device 1 and protects the floor surface and the cooling unit. This prevents contact with the Reference numeral 15 denotes a heat insulating seal member made of a soft fin piece disposed around the opening C, and reference numeral 16 denotes a heat insulating seal member disposed on the inner side surface of the outer body 5 serving as a buffer.

According to this configuration, since the heat insulating plate 6 and the inner body 7 are attached to the outer body 5 with bolts 8 and nuts 9, and the guards 14, 14 are attached to the inner body 7, it is difficult to attach the guard 14. The installation work requires two steps, and when the outer body 5, insulation board 6, and inner body 7 are jointly tightened with bolts 8 and nuts 9, the insulation board Due to the elasticity of the bolt 6, it is difficult to tighten the nut 9, and if the nut 9 is tightened too much, the head of the bolt 8 warps both ends of the inner body 7, making it difficult to secure the guards 14, 14 to the inner body 7. occured. Also, guard 1
4 and 14 have strength in the longitudinal direction, but have weak strength in the counter-longitudinal direction and have the disadvantage that when the refrigeration equipment 1 is installed on the floor, it will tilt due to impact from the counter-longitudinal direction. occured.

The present invention has been developed in view of these drawbacks, and examples thereof will be described below with reference to FIGS. 4 to 6.
Note that in FIGS. 4 to 6, the same reference numerals as in FIGS. 1 and 3 are the same.

6a is a notch formed by cutting out each of the square parts of the heat insulating plate 6, and 7b is a notch formed by cutting out each of the square parts of the inner body 7, corresponding to the notch of the heat insulating board. be. Reference numerals 17, 17 denote pressing parts that connect the two guards 14, 14 to each other and press the inner body 7 toward the outer body when both the guards are attached. The two guards include a mounting portion 14a that is fixed to the inner side surface of the outer body 5 with a fastener 13 such as a screw or screw, both cutout portions 6a of the heat insulating plate 6 and the inner body 7,
7b, a support portion 14c that prevents the heat insulating plate and the inner body from moving in the lateral direction, and a protection portion 14b that surrounds the cooling unit.

By fixing the guards 14, 14 to the outer body 5, the heat insulating plates and the inner body are pressed directly and indirectly in the direction of the outer body by the pressing parts 17, 17, and laterally by the support part 14c. movement is prevented and fixed.

According to this configuration, when the refrigeration device 1 is installed on the floor and after being placed in the refrigerator A, the heat insulating plates 6 and the inner body 7 are pressed at the same time as the guards 14, 14 that protect the cooling unit are attached to the outer body 5. Since the parts 17, 17 and the support part 14c can be fixed together, the heat insulating plate 6 and the inner body 5, which are necessary for heat insulation and installation of the cooling unit, can be fixed simply and quickly and with a reduced number of parts. 14, 14 itself can be improved in strength.

As described above, in the present invention, since notches are formed in the heat insulating plate and the inner body, and a pressing part is provided in the guard, the heat insulating plate and the inner body can be fixed to the outer body at the same time as the guard is installed. The installation work is extremely simple and can be done with a reduced number of parts.
