BACKGROUND OF THE INVENTION
The present invention relates to a flat open showcase in which the upper part of a product display portion formed in a box shape with an open top is surrounded by a windshield transparent plate, and more particularly to a flat open showcase having an improved cold air inlet.
[0002]
[Prior art]
In self-service food stores such as supermarkets, flat-type frozen / refrigerated open showcases with an open top are often used for display of refrigerated foods and frozen foods.
[0003]
FIG. 4 and FIG. 5 show an example. A flat open showcase 21 includes a box-shaped product display portion 22 having an open top, and a pedestal that holds the product display portion 22 at an appropriate height. The refrigerator 23 is housed in the pedestal 23. Further, the side wall 24 around the product display section 22 is formed of a transparent plate 24a made of glass or the like on the upper windshield plate and a panel 24b having a heat insulating function on the lower portion. , And are supported by support columns 25 and upper rails 26 provided at the four corners.
[0004]
Further, the bottom plate portion 22 a of the product display portion 22 is formed in a double structure, and a cold air circulation duct 29 including a cooler 27 and a blower 28 is provided. Both ends of the circulation duct 29 are in communication with the cold air outlet 30 and the cold air inlet 31, and the air cooled by the cooler 27 is blown out from the cold air outlet 30 into the product display unit 22 to enter the product display unit. Is maintained at a predetermined cooling temperature, and is sucked into the circulation duct 29 from the cold air inlet 31 and circulates in this path by the action of the blower 28.
[0005]
The conventional cold air outlet 31 is provided at the upper end of the cold air passage 34 formed between the inlet fence 33 made of a transparent material such as a transparent synthetic resin such as acrylic and the side wall 24 which is installed in parallel with the inner surface of the side wall. The upper part is opened.
[0006]
[Problems to be solved by the invention]
By the way, the conventional cold air suction port 31 has an opening in the upper and lower direction, so that when the cold air is sucked, outside air with high humidity is caught and invaded, and a large amount of frost is attached to the cooler 27. There was a problem.
Therefore, it takes time for defrosting and the cooling duration has been reduced.
Further, since the conventional suction port fence 33 is screwed to the partition plate between the suction port duct just below the suction port punching hole and the product display part, it cannot be easily removed, and dust such as dust near the suction port can be removed. It was difficult to clean.
In addition, when the cooling operation of the case progresses and the regular inlet punching hole is clogged with frost, cold air is not sucked from the inlet punching hole, cold air does not flow into the cooler, and low-pressure cutting is frequently performed There was a problem that the case operation stopped.
[0007]
The present invention was devised in view of the above points, suppresses intrusion of outside air as much as possible, reduces the defrost time of the cooler, is easy to attach and detach the cold air suction port, and is easy to clean dust etc., and An object of the present invention is to provide a flat-type open showcase in which low-pressure cut does not occur even when the cooling operation of the case proceeds and the suction hole punching hole is clogged with frost.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, a cold air outlet is provided that surrounds the upper part of the circumference of the product display portion formed in a box shape with an open top with a windshield transparent plate and blows out cold air to the other side. In the flat open showcase having the cold air inlet on the other side, the cold air inlet is blocked by folding the outer plate at the opening in the vertical direction at the upper position, and the bent portion tip of the outer plate, The suction port kit is configured to suck in cold air from a horizontal opening formed between the upper end of the inner plate and the suction port kit includes an inverted L-shaped outer plate and a flat inner plate. The lower part of the inner plate is formed longer than the outer plate so that it can be inserted into a fixed rail provided on the case, and is provided on the case. In addition, the partition plate at the bottom of the fixed rail It is characterized by formed by drilled ring hole.
[0009]
By adopting the above configuration, it is possible to suppress the outside air to be sucked in from the upper direction as much as possible, and to increase the cold air sucked from the horizontal direction and the lower direction. The vessel is less likely to be frosted and prolonged cooling. In addition, since a punching hole for sucking cold air is formed in the partition plate below the fixed rail of the case, even when the regular suction hole punching hole is clogged, cold air can be sucked from the punching hole of this partition plate. This is preferable.

【The invention's effect】
As described above, the flat open showcase of the present invention has the following effects.
(1) The cold air inlet is configured by a suction inlet kit, and the upper and lower vertical openings are blocked by folding the outer plate of the kit, and the end of the bent portion of the outer plate and the upper end of the inner plate of the kit Since the cold air is sucked in through the horizontal opening formed between the two, the outside air that is sucked in from the upper direction can be suppressed as much as possible, and the cold air sucked in from the horizontal direction and the lower direction can be increased. . As a result, the intake of outside air is reduced and air with low humidity flows, so that the cooler is less likely to form frost, the defrost time is reduced, and the cooling duration is extended.
(2) The suction port kit is formed by fixing an inverted L-shaped outer plate and a flat inner plate with spacers between them with spacers, and fixing the suction port kit to the case is as follows. The lower end of the inner plate that is longer than the lower side of the outer plate is inserted into a fixed rail provided on the case and fixed. For this reason, the kit can be easily detached and easily cleaned.
(3) If the suction port kit is made transparent , the products in the warehouse can be seen from the outside while maintaining the cooling performance.
(4) Since the partition plate under the fixed rail of the case is provided with a punching hole for cold air suction, when the regular suction hole punching hole is clogged with frost, cold air is sucked from the punching hole for cold air suction (Normally, almost no cold air is sucked in), and a constant air flow can be made to the cooler at all times, so that a low pressure cut hardly occurs. Therefore, a situation in which the operation of the case frequently stops can be avoided.
