[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerated showcase, and more particularly to a novel frame structure thereof.

[0002]

2. Description of the Related Art In a refrigerated showcase, the front surface is made of a transparent glass so as to show refrigerated food in a display room to a customer or the like, while the rear surface is a glass for putting in and out the refrigerated food and grasping the inside condition. In many cases, it is made of sliding doors.

FIG. 6 shows an example of a mounting structure of a lower rail B of a sliding door A in a conventional refrigerated showcase. The glass sliding door A forming the rear surface of the display room C slides on the slider D inside the rail B. The frame body E formed integrally with the rail B receives and supports the bent end of the bottom plate F of the display room C between the fitting support portion Ea that protrudes in the lateral direction and the rail B. The rear structural member I forming the rear end of the heat insulating structure H of the machine room G is formed integrally with the rear decorative frame J and supports the lower end of the main body Eb of the frame E.
A rear cover K of the machine room G is attached to the rear structural member I, and an upper end of the decorative frame J forms a boundary wall at an outermost end of the rail B. A seal member L is interposed between the main body Eb of the frame E and the decorative frame J.

[0004]

In the construction described above, the main body portion Eb of the frame E has a function of maintaining the vertical interval with the bottom plate F, and the rail B and the decorative frame J are separate bodies. Therefore, even if there is a manufacturing error in each member, assembly becomes easy, but the groove width of the outer rail is not stable, and a gap is generated. Water droplets adhere to the inner surface of the sliding door A, so that moisture passes through the gap and the passage M between the bottom plate F and the heat insulating structure H.
Infiltrated into the garbage, causing decay and odor. Further, when the groove width of the outer rail B is wide as described above, a gap is easily formed between the sliding doors A, and the cooling efficiency may be deteriorated due to leakage of cold air inside.

[0005] In addition, moisture that has entered between the bottom plate F and the rail B may flow into the passage M and cause the same problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems. The sliding door on the rear side of the display room is stable and does not lower the cooling efficiency. It is an object of the present invention to provide a frame structure of a refrigerated showcase that does not cause a problem.

[0007]

In order to achieve this object, according to the present invention, a display room for accommodating objects to be displayed is provided at an upper portion, and a machine room containing a refrigeration system is provided at a lower portion, respectively. A rear surface of the display room is formed of a sliding door, a boundary between the machine room and the display room is formed of a plate-like heat-insulating structure, and a bottom plate that defines a cool air circulation passage in cooperation with the heat-insulating structure is provided. In a refrigerated showcase provided at a lower portion in the display room, a spacer member integrally formed with a rear end surface structural member of the heat insulating structure extends and is bonded to a lower surface of the bottom plate, and the display room and the display room are connected to each other. A rear decorative frame body located at the boundary of the machine room is formed integrally with a rail supporting the sliding door, and the rail is positioned on the rear surface side of the spacer member on the rear end surface structural member. It is placed.

[0008]

The spacer member formed integrally with the rear end face structural member of the heat insulating structure supports the bottom plate to define a cool air passage, and completely prevents moisture from entering the cool air passage. Is formed integrally with the rear decorative frame to support the lower end of the sliding door, and the lower part of the groove for receiving the sliding door is completely closed to prevent the permeation of moisture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

As shown in the front perspective view of FIG. 1 and the rear perspective view of FIG. 2, a refrigerated showcase 1 generally called a "sputter case" has a display room 2 at an upper part and a machine room 3 at a lower part. The rear surface of the machine room 3 is covered with a rear cover 5, and the display room 2
The rear surface is formed by two sets of sliding doors 7, the display room 2 and the machine room 3
Are separated by a decorative frame 9.

As shown in FIG. 3, which is a longitudinal sectional view taken along the line III-III of FIG. 1, the display room 2 includes an inner box 1 including a bottom plate 11.
3 and a cool air circulation passage 15 is defined around the inner box 13.

A plate-like heat-insulating structure 17 which cooperates with the bottom plate 11 to define a lower portion of the cool air circulation passage 15 forms the lowermost portion of the display room 1, and the machine room 3 thereunder has refrigerant compression. Machine 21
And a condenser fan 23. Thermal insulation structure 1
7 is provided with an opening, and at this opening, a cooler room 25 of the machine room 3 communicates with the cool air circulation passage 15, in which a cooler 27 and a cool air circulation fan 29 are provided. Have been. A tubular condenser is provided below the cooler chamber 25, and the high-temperature, high-pressure refrigerant sent from the compressor 21 is cooled by the wind from the condenser fan 23 in the condenser,
Condense.

FIG. 4 is a sectional view taken along the line IV-IV of FIG. 3, and as is apparent from this figure, the bottom plate 11 of the display room 2 is shown.
The heat-insulating structure 17 and the heat-insulating structure 17 are both inclined so that the rear side is higher, so that the display object placed on the bottom plate 11 can be seen well through the windshields 31 and 33.
The rear of the machine room 3 is closed by a rear cover 5, while the rear of the display room 2 is closed by a sliding door 7.

FIG. 5 is an enlarged view showing the details of the rear end face portion of the bottom plate 11 and the heat insulating structure 17. The rear end structural member or frame 40 includes ribs 41 and 42 for receiving and fixing the lower plate 17a of the heat insulating structure 17, and ribs 43 and 44 for receiving and fixing the same upper plate 17b. . From the upper surface of the rib 44, a spacer member, that is, a spacing member 46 rises, extends to the lower surface of the bottom plate 11, and is adhered to the lower surface. In this way, the spacing member 46 separates the cool air circulation passage 15 from the right space and secures its height.
