Description

[Detailed description of the invention] This invention prevents vibrations from equipment such as compressors from being transmitted to the refrigerated showcase body, and also makes it easier to pull out equipment from the refrigerated showcase body, allowing equipment to be repaired, inspected, etc. Conventionally, equipment such as a compressor installed in the lower part of a refrigerated showcase as shown in Fig. 1 is fixed to the refrigerated showcase body, so the amount of air generated from the equipment is The vibrations are transmitted to the refrigerated showcase body, causing the entire refrigerated showcase to vibrate, producing noise and hindering operations such as equipment repair and inspection.

Taking the above points into consideration, this invention minimizes the vibration of the refrigerated showcase and improves the workability of repairing and inspecting the equipment. This will be explained in detail with reference to the drawings shown in FIG. 2 and the following drawings.

Reference numeral 1 indicates a base that constitutes the frame of the refrigerated showcase, and 2 indicates a heat insulating box provided with a base member.
The interior of the refrigerator is inside the refrigerator.

3... are main body supporting tools such as main casters, which are provided in total four on both front and rear sides of the lower surface of the base body 1, and this main body supporting tool 3
This allows the refrigerated showcase body to be moved freely.

4 is a cold air circulation path formed inside the insulation box 2; 5, 6;
41 is a cold air discharge port and a cold air intake port formed at the upper and lower ends of the cold air circulation path 4; 718 is a cooler and a supply/discharge fan provided in the cold air circulation path 4, respectively, and drives the supply/discharge fan 8; According to the ratio, air circulates through the inside of the refrigerator, the inlet 6, the cooler 7, the supply/exhaust fan 8, the outlet 5, the inside of the refrigerator, and the cold air circulation path 4, and the air is cooled by the cooler 7 and returned to the refrigerator. The inside is cooled down.

9... is a display shelf provided in the warehouse, 10.10 is a metal frame with a cross-section shaped like a cross section mounted and fixed on the base 1, and the base 1 and the metal frame 10゜1, wholesaler. - An opening 11 is formed in the lower surface of the case body.

12 is a mounting board located above the opening 11, and both sides of the mounting board 12 are bent downward.
has a width that prevents it from falling out of the opening 11 when the main body of the refrigerated display case is lifted up during transportation or the like.

13, 14, and 15 are a compressor, a condenser, and a blower fan attached to the upper surface of the mounting board 12, and the compressor 13, condenser 15, cooler 7, etc. constitute a refrigeration cycle.

Reference numerals 16 and 16 denote rails fixed to the lower surface of the mounting board 12 in parallel to the left and right, and both sides of the rail 16 are bent into a cross-sectional shape to form rail grooves 17 and 17.

Reference numeral 18.18 denotes a mounting plate fitted into each rail groove 17.17, and the mounting plate 18 slides back and forth along the rail 16.

19... are substrate supports such as auxiliary casters that are attached to the front and rear of each mounting plate 18, 18 via support rods 20, and both the compatible holders 3 and 19 are in contact with the installation surface 21. At this time, the mounting board 12 is placed in a floating state above the base body 1 and the metal frame 10.

22... is a support plate fixed to the upper end of each support rod 20 and the lower surface of each mounting plate 18, 23... is a support plate that passes through the mounting board 12 and the rail 16.16 to the front part of the mounting plate 18. The bolt 23 is a bolt that is screwed into the mounting plate 18.
movement within the rail 16 is prevented.

Therefore, in the embodiment described above, during the freezing operation of the refrigerated showcase, vibrations generated from devices such as the compressor 13 and the blower fan 15 are transmitted to the mounting board 12;
The mounting board 12 is placed separately from the refrigerated showcase main body by the board support 19, and the mounting board 12 is lifted from the base 1 and the metal frame 10, so that vibrations from the equipment are not transmitted to the refrigerated showcase main body. .

In addition, when repairing or inspecting equipment, when the bolts 23 are removed to allow the mounting plate 18 to slide freely on the rail 16 and the mounting board 12 is pulled out forward, the front end of the mounting plate 18 will come into contact with the base 1, and the mounting plate 18 will slide freely onto the rail 16. 18. The board support 19 remains in the opening 11 and is pulled out of the refrigerated showcase main body where the mounting board 12 to which the equipment is attached is located, allowing the equipment to be easily repaired and inspected.

Note that the mounting board 12 is pulled out within the range in which the connecting pipe of the refrigeration cycle can be expanded and contracted.

After the repair and inspection are completed, the mounting board 12 is pushed back into the refrigerated showcase main body, the mounting board 12 and the mounting plate 18 are integrated with the bolts 23, and the equipment is installed in the lower part of the refrigerated showcase.

As mentioned above, according to the refrigerated showcase of this invention,
An opening is formed on the bottom surface of the main body equipped with a main body support that contacts the installation surface, and rails are fixed horizontally and parallel to the bottom surface of the mounting board for equipment such as compressors, so that both can slide freely on these rails. A compressor, etc. is constructed by attaching a board support that comes into contact with the installation surface of the mounting plate, and making the board support come into contact with the installation surface through the opening to float the mounting plate above the opening and make it difficult to connect with the main body. Since the vibrations of the equipment are not transmitted to the refrigerated showcase body, the vibration of the refrigerated showcase can be minimized and noise can be reduced.

Additionally, the equipment can be easily pulled out of the refrigerated showcase body, improving workability in repairs and inspections.
