BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low temperature flat open showcase used in a small store such as a convenience store, and in particular, an air curtain for outside air is formed in place of a conventionally used door. The present invention relates to a flat open showcase that makes it easy to keep products in and out while keeping them cool.

[0002]

[Prior Art] In small stores such as convenience stores,
An example of a low-temperature flat-type showcase for keeping and displaying ice cream and the like is shown in FIGS.

As shown in FIGS. 4 and 5, the flat-type showcase 21 has a product storage portion 2 formed in a box shape with an open top.
2 and a pedestal part 2 for keeping the product storage part 22 at an appropriate height
And 3. The product storage unit 22 is
It is surrounded by an exterior panel 24 having an integrated foam panel structure.

As shown in detail in FIG. 5, a cooling air circulation duct 25 is formed between the exterior panel 24 and the product storage unit 22 in a predetermined space. Is provided with a cooler 26 and a blower 27. The air cooled by the cooler 26 is used for the product storage unit 22.
After the ice cream or the like (not shown) stored in the product storage unit 22 is cooled by being blown out from the rear outlet port 28 to the front of the product storage unit 22, the suction port 29 on the front side of the product storage unit 22 is again used. It has a structure of being circulated in the circulation duct 25.

By the way, when this type of flat-type showcase 21 having the opening 30 at the top is used in a small store such as a convenience store, outside air outside the store may enter through the entrance, resulting in air conditioning in the store. Is likely to be a bad environment. Therefore, in low-temperature specification showcases (especially ice cream specifications), an air blanket (the entire product is covered with cold air) by sucking in unnecessary air from the bad environment.
Since the state collapses, a door (sliding door or the like) 31 is installed to effectively keep the inside of the showcase cold.

[Problems to be Solved by the Invention] However, if there is a door,
There has been a problem that it takes time to take out and take out the product, because the product has to be opened and closed when taking it in and out. There was also the problem that it was difficult to see the products in the warehouse.

Therefore, according to the present invention, there is no need to take the goods in and out, and the goods in the warehouse can be easily seen.
The challenge is to provide a flat open showcase that also has a high cooling effect.

[0008]

In order to solve the above-mentioned problems, in the present invention, an opening for taking in and taking out products is provided above the product display section, and this opening is covered with a cool air curtain. In a flat open showcase that keeps the inside cool, a fan unit including an outside air inlet, a fan motor, and an outside air outlet is provided above the opening, and the opening is formed by the air curtain of the outside air formed by this fan unit. It is characterized by covering around.

In the flat open showcase of the present invention,
Under the outside air inlet provided on the upper part of the fan unit,
It is preferable to arrange a plurality of fan motors, provide a contact plate for the outside air blown from the fan motors on the downstream side, and distribute the outside air to the left and right to blow the outside air. Further, it is preferable that the outside air blown out from the fan unit is formed with an air curtain so as to cover the outside of the showcase in the longitudinal front direction, and shield plates are provided on both short sides of the showcase. Further, it is convenient that the fan unit provided above the opening of the showcase is provided with a lighting device for illuminating the interior of the case below and the lighting shade also serves as a guide plate for blown outside air.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail with reference to the drawings. 1 is a perspective view of the flat open showcase, FIG. 2 is a partially enlarged perspective view of the flat open showcase, and FIG. 3 is a sectional side view of the flat open showcase.

As shown in FIGS. 1 to 3, the flat open showcase 1 has a box-shaped product storage section 3 having an opening 2 open at the top, and the product storage section 3 has an appropriate height. The pedestal portion 4 is provided with a pedestal portion 4 which is kept upright, and a top plate 6 which is supported above the opening portion 2 by columns 5 which extend upward from both sides of the product storage portion 3 and which includes a fan unit F. ing. The display portion of the product storage unit 3 is surrounded by the exterior panel 7 having an integrated foam panel structure.

A predetermined space is provided between the display section of the product storage section 3 and the exterior panel 7, as shown in detail in FIG.
A circulation duct 8 for cold air is formed. Then, in the underfloor circulation duct of the product storage unit 3, the cooler 9 and the blower 10 are provided.
And the air cooled by the cooler 9 is installed in the commodity storage unit 3
From the air outlet 11 on the rear side (one side in the longitudinal direction) to the product storage unit 3
Is blown out to the front side (the other side in the longitudinal direction) of the display section and the opening 2 is covered with a cool air curtain CA to keep the ice cream or the like (not shown) stored in the display section of the product storage section 3 cool. The air that has cooled the ice cream or the like is sucked from the suction port 12 on the front side of the product storage unit 3 and is circulated again in the circulation duct 8.

The top plate 6 has an inverted dish shape in cross section and has a plurality of fan units F, F ... That is, the fan unit F is located at the outside air suction ports 13, 13 ... Perforated in the top plate 6, the fan motor 14, and on the downstream side of the fan motor 14 so that the outside air blown out from the fan motor 14 is left and right. Contact plate for dispersion into 1
5 and outside air outlets 16 and 16 in two front and rear directions, which are formed of a honeycomb structure or the like. The outside air blown from the fan unit F forms an air curtain GA so as to cover the outside of the showcase 1 in the longitudinal front direction.

Further, transparent acrylic shielding plates 17, 17 are provided on both sides of the showcase 1 in the lateral direction. Further, a transparent outside air guide plate 18 is provided below the outside air outlet 16, and on the other hand, before and after the product storage section 3, the blown outside air air curtain GA does not flow into the showcase cabinet. A windshield plate 19 formed by being bent inward is provided.

The contact plate 14 of the fan unit F
An illumination device L for illuminating the interior of the showcase may be provided on the back side (lower side) of the, and the illumination shade 20 may also serve as a guide plate for blown outside air.

When the fan unit F is constructed in this way, the outside air is sucked by the fan motor 14 from the outside air inlets 13, 13, ...
5 and is dispersed to the left and right, and the outside air outlets 16, 16
From this, the air curtain GA for a guard is formed toward the outside of the windshields 19 and 19 in front of and behind the product storage unit 3. Therefore, the air curtain GA prevents outside air from entering the showcase cabinet, so that the conventional door (sliding door) is not required and the product can be taken out without opening and closing the door. Further, since there is no door, the goods in the refrigerator can be clearly seen from the outside of the showcase 1. Since the air curtain GA for the guard is an air curtain for the outside air, there is no concern about so-called cold aisle, which causes cold air to stay around the floor of the store and makes the customer uncomfortable.

[0017]

As described above, according to the present invention,
It has the following excellent effects. By forming the outside air curtain in place of the door, it is possible to prevent outside air from entering the inside of the refrigerator, and to take products in and out without opening and closing the door (sliding door). Because the outside air curtain covers the outside of the showcase, there is little correlation with the cooling air curtain, and the cooling air curtain can adopt its own low air velocity blanket structure. Since the outside air does not enter the storage (the load is small),
Even though it is an open showcase, the defrosting frequency is 1 per day.
The number of times (normal open showcase is 3-4 times a day) can be reduced, and as a result, the defrosting electricity bill can be saved and
Frost on the product package caused by the temperature rise in the defrosting chamber can be dramatically reduced.
