Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold air circulation type showcase, and more particularly to an assembly structure of a lower front part of a refrigerator suitable for a reach-in type showcase.

[0002]

2. Description of the Related Art First, FIG. 3 shows a general structure of a reach-in type showcase of a cold air circulation type which is an object of the present invention. In the figure, 1 is a case body having a substantially U-shaped cross-section with an open front surface, 2 is a glass door attached to the front surface of the case body 1, and the case body 1 is an outer box 3 and an inner box formed as a heat-insulating housing. 4, the inner box 4 is equipped with product display shelves 5 arranged in the upper and lower stages. Also, the outer box 3 and the inner box 4
A cold air circulation duct 6 is defined between the cooling air circulation duct 6 and the bottom of the outer box 3 called a boat bottom, and a cooler 8 and a fan 8 are incorporated therein, and a deck pan 9 is detachably mounted and supported on the upper surface thereof. Has been done. Further, the cold air outlet of the cold air circulation duct 6 is opened at the upper front part of the inside of the refrigerator, and the cold air suction port is opened at the front side of the deck pan 9. The cold air suction port sucks the cool air on the upper surface of the long plate. A return grill 10 is provided with many holes punched. In addition, 11 is a pillar that supports the product display shelf 5, 12 is a door support frame of the glass door 2, 1
Reference numeral 3 is a fluorescent lamp for internal lighting.

Next, FIG. 2 shows an assembly structure of a lower part of a front part of the interior of the conventional showcase. In the figure,
Support metal fittings 13 are fixed by screws along the inner side of the door support frame 12 at several points on the upper surface of the boat bottom of the outer casing 3, and are bridged over the support metal fittings 13 between the shelves (see FIG. 3). A long-sized return grill 10 is placed on the return grill holder 14 laid on the. On the other hand, the deck pan 9 having a rectangular plate surface has its rear edge supported by the lower end of the rear panel of the inner box 4 as shown in FIG. 3, and further has both left and right edges between the lower portion of the shelf column and the rear panel. It is carried on a cross-shaped deck pan receiver (not shown) that has been passed over, and the front edge is overlapped with the rear edge of the return grill receiver 14 so as to partition the inside and the bottom of the boat.

[0004]

By the way, in the above-mentioned conventional assembly structure, the support metal fitting 13 and the components of the return grill holder 14 are necessary for attaching the return grill 10, and further the deck pan holder for supporting the deck pan 9 is attached. It requires a lot of parts to assemble, such as the need for special clips on the shelf posts. For this reason, the structure is complicated and the number of assembling steps is large, and the assembling work requires a lot of labor and time, which is a factor of increasing the cost.

The present invention has been made in view of the above points, and an object thereof is to solve the above problems and provide a showcase in which a return grill and a deck pan can be easily assembled with a small number of supporting parts and assembly steps. To do.

[0006]

In order to achieve the above object, according to the constitution of the present invention, a deck pan receiving portion for mounting and supporting a front edge portion of a deck pan is formed at a rear edge portion of the return grill, and the return grill is formed. Shall be bridged between the left and right supporting metal fittings fixed to the upper part of the front side of the boat bottom, and the front edge of the deck pan shall be placed and supported directly on the deck pan receiving part formed at the rear edge of the return grill.

For the reach-in type showcase, the return grill is arranged inside the door support frame of the glass door attached to the front surface of the case body. According to the above configuration, the return grill can be placed only on the support fitting fixed to the boat bottom on the case body side, and the deck pan can be supported by the deck pan receiving portion formed at the rear edge of the return grill. No other special supporting parts are required, which simplifies the assembly structure of the lower part of the front part and reduces the number of supporting parts and the number of assembling steps.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In the drawings of the embodiment, the same members corresponding to FIG. 2 are denoted by the same reference numerals. That is, in the configuration of FIG. 1, a deck pan receiving portion 10a is formed by sheet metal working on the rear edge side of the return grill 10 made of a steel plate so as to form a step portion along the longitudinal direction thereof.
Then, the return grill 10 is laid on the inside of the door support frame 12 of the front glass door (see FIG. 3) by being laid over a rib-shaped support fitting 13 screwed to several places on the upper surface of the boat bottom of the outer case 7. It On the other hand, the deck pan 9 installed on the upper surface of the bottom of the boat has its rear edge supported on the lower end of the rear panel of the inner box as in the conventional case, and the front edge of the deck pan 9 is dropped on the deck pan receiving portion 10a of the return grill 10 directly. Supported.

Although the illustrated embodiment is applied to the reach-in type showcase shown in FIG. 3, it can be applied to a multi-stage open showcase as well.

[0010]

As described above, according to the structure of the present invention, the structure is greatly simplified as compared with the conventional assembly structure, and the number of parts and man-hours required for attaching the return grill and the deck pan can be reduced, so that the showcase can be realized. It also greatly contributes to cost reduction.
