DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cool air circulation type open showcase having a U-shaped cross section having a product take-out opening on the front surface and having a compartment inside thereof.

[0002]

2. Description of the Related Art FIG. 3 shows a known cool air circulation type open showcase. In the figure, the open showcase includes a case body 1 having a U-shaped cross section and having a product take-out opening 1a on the front surface. The case main body 1 forms an interior 2 inside, and the interior forms an air passage 3, in which a fan 4 and a cooler 5 are arranged. Both ends of the ventilation passage 3 are open toward the opening 1a to form an outlet 3a and an inlet 3b. A shelf 6 for partitioning the inside of the compartment up and down is provided in the compartment 2. On the other hand, a canopy 7 is attached to the upper front end of the case main body 1, and electric equipment such as a ballast of a fluorescent lamp 8 for illuminating the front of the open showcase and a product in the refrigerator is built in. And the open showcase above is for fan 4
As a result, the air in the refrigerator is drawn into the ventilation passage 3 from the suction port 3b, becomes cooling air in the cooler 5, and circulates through the ventilation passage 3 as shown by the arrow. A cold air curtain is formed to shield from the outside air, and the inside of the refrigerator (2) is cooled, and the products displayed and stored in the refrigerator (2) are refrigerated. Further, the open showcase is generally used by connecting a plurality of open showcases side by side.

As shown in FIG. 4, the case body 1 is provided with U-shaped frames 11 having appropriate widths on both left and right sides, and a heat insulating plate is fixed to the outside of the frame 11 to form an outer box 12. While being formed, the inner box 13 is formed by a thin iron plate member attached inside. Thus, the inside of the inner box 13 forms the interior 2, and a gap surrounded by the left and right frames 11 and provided between the outer box 12 and the inner box 13 forms the ventilation path 3. The frame 11 is generally formed in a U-shape by welding the rear ends of a top frame 22 and a bottom frame 23 extending forward and rearward to upper and lower ends of a rear support column 21 standing upright at a back portion. Also top frame 2
The canopy 7 is attached to the front end of the canopy 2.

[0004]

In the conventional open showcases, the upper front end of the case body 1 is bent downward by the load of the canopy 7 or the like, and when arranged side by side, irregularities are formed in the upper portions of the adjacent open showcases. There was a disadvantage that it became difficult to see. In order to solve this disadvantage, the thickness of the frame 11 is increased,
However, in the former case, since the entire frame 11 must be formed with a considerable size and thickness, there is a problem that the weight of the case body is greatly increased and the manufacturing cost is greatly increased. In the latter case, there is a problem that the ventilation passage 3 is divided into right and left.

[0005] The present invention does not cause the above disadvantages,
It is an object of the present invention to provide a case body in which an upper front end is beautifully aligned when an open showcase is connected.

[0006]

According to the present invention, in order to achieve the above-mentioned object, a plurality of U-shaped cross-section frames are provided at appropriate intervals in the lateral direction with an opening in the front, and An outer box formed of a heat insulating wall on the outside, and an inner box formed inside the frame, wherein an inner space is formed inside the inner box, and between the outer box and the inner box. In a case body of a cool air circulation type open showcase having a ventilation path for cooling air formed therein, an upper frame extending forward from an upper end of a rear support of the frame, a rear end portion is connected to the rear support and extends forward. A top frame, having an adjusting means provided on the upper surface along the top frame and having a rear end fixed to the rear support and adjustable vertically, and a front portion is supported by the top frame. Supplement It shall constitute a frame.

[0007]

A reinforcing frame is provided on a conventional top frame, and an outer box is formed outside the reinforcing frame. Since the front end of the reinforcing frame is pushed up by the adjusting means and the height of the outer box is kept at a predetermined position, the height can be made uniform when the open showcases are connected.

[0008]

1 and 2 show an embodiment of the present invention, in which the same or similar parts as those in FIGS. 3 and 4 are denoted by the same reference numerals. 1 and 2, a frame 11 of a case body 1 is a reinforcing frame 2 having a U-shaped cross section which extends back and forth along a top frame 22 on a conventional top frame 22.
4 are provided, and the upper frame 25 is configured. A screw hole is formed in a front portion of the top frame 22, and an adjustment bolt 26 screwed into the screw hole is provided. Reference numeral 27 denotes a fixing nut screwed into the adjustment bolt 26. The rear end of the reinforcing frame 24 overlaps the upper end of the rear column 11 and is fixed with small screws 28, and the upper end surface of the adjusting bolt 26 contacts the lower surface of the front. Further, the ceiling plate of the outer box 12 is fixed on the upper surface by small screws 29, and the canopy 7 is attached to the front end.

In the above-described configuration, since the upper frame 25 is composed of the top frame 22 and the reinforcing frame 24, the case body 1 is extremely bent at the upper front end even when a load such as the canopy 7 containing the electric components is applied. Small. Further, even with the slight bending, the reinforcing frame 24 can be pushed up to correct the upper front end of the frame 11 to a predetermined height by screwing the adjustment bolt 26 from below the top frame 22. In this corrected position, the fixing nut 2
7, the tightening adjustment bolt 26 is fixed to the top frame 22, and the frame 11 is held in the corrected state. The open showcases connected side by side are Canopy 7
Are lined up and look good. Further, since the case body 1 merely adds the reinforcing frame 24 to the frame 11, the weight and cost are slightly increased, and the cooling air can be circulated as in the conventional case.

[0010]

According to the present invention, a plurality of U-shaped cross-section frames are provided at appropriate intervals in the lateral direction with the opening in front, and an outer box formed of a heat insulating wall outside the frame.
Cold air which is constituted by an inner box formed inside the frame, has an inner space formed inside the inner box, and has a cooling air passage formed between the outer box and the inner box. In a case body of a circulation type open showcase, an upper frame extending forward from an upper end of a rear support of the frame, a top frame having a rear end coupled to the rear support and extending forward, and an upper surface extending along the top frame. Since the rear end is fixed to the rear column and has adjusting means that can be adjusted in the vertical direction, and the front portion is constituted by the reinforcing frame supported by the top frame, the weight is increased. The top front edge is lined up without any significant increase in cost and cost, and no trouble in cooling air circulation. It is possible to provide a case body that can be.
