Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open showcase in which a front surface of a casing is opened to form a product inlet / outlet, and more specifically, it is used for displaying frozen / refrigerated food products in food stores. The present invention relates to a structure for mounting a night cover, which is more energy-saving in a frozen / refrigerated open showcase.

[0002]

2. Description of the Related Art In a self-service food store such as a supermarket, a frozen / refrigerated open showcase as shown in FIGS. 8 to 10 is used to display refrigerated food and fresh food.

The open showcase 51 has a plurality of shelves 53, 53 provided in a casing 52, for example.
... A product such as food is placed on the upper rail, and cool air is rectified and blown out as an air curtain from a cool air outlet 54 provided in the upper portion to the lower side of the casing 52 to form a lower exterior of the front opening of the casing 52. Cold air intake 5 provided on the back
In addition to sucking the cool air from 5, the cool air is sent to the cooler from the lower part of the duct 57 provided between the casing 52 and the inner panel 56 by a blower, and the products in the casing 52 are cooled by the continuation of this cycle.

The upper front end of the casing 52 is covered with a canopy 58 which serves as a ceiling exterior.
A canopy illumination 59 is disposed below the canopy illumination 59, and the light from the canopy illumination 59 is reflected by the canopy top plate 58a so as to illuminate the inside of the cabinet uniformly. Further, in front of the cool air outlet 54, there is formed a nosing portion 60 which is connected to the canopy top plate 58a and covers the front portion thereof. Inside the nosing portion 60, a dew-proof heater and a remote thermometer 63 for displaying the temperature inside the refrigerator are provided. The body of is arranged. Then, a roll-shaped shielding curtain 62 is provided immediately in front of the front wall of the nosing portion 60 of the canopy top plate 58.
A night cover 62 including N is attached, and when the store is closed at night, the shielding curtain 62N is pulled out to cover the opening of the showcase 51 to reduce the load on the showcase.

[0005]

By the way, as shown in FIG. 8, the shielding curtains 62N, 62N wound in a roll form have a length of about 3 cm (about 90 cm) to 4 shaku (about 90 cm) in consideration of easy opening and closing. It is manufactured with a frontage size of about 120 cm, and the night covers 62, 62 are linearly attached in series to the showcase. Therefore, there is also a structural limitation of the night covers 62, 62, and the shielding curtain 62 of the adjacent night covers 62.
A gap C of 10 to 20 mm was generated between N and 62N.
Therefore, the inside of the showcase has a negative pressure, and when the night cover shielding curtains 62N and 62N are shielded at night or the like, the gap C is generated.
From the above, the phenomenon that the outside air is sucked into the storage occurred, and the energy saving rate was only about 20 to 28% in the use of meat and fresh fish compared to when the night cover was not used.

[0006] Therefore, the applicant of the present invention, the previous March 15, 1995
In Japanese Patent Application No. 7-83383 filed for a patent on the date, the end portions of the shielding films of the adjacent night covers are overlapped with each other, and the night cover is not formed under the same material and the same temperature condition as the conventional night cover and showcase. We proposed an open showcase that saves about 39 to 48% energy when used.

However, with the night cover mounting structure of this open showcase, when viewed from the side of the shielding film when the night cover is used, there is a slight gap between the overlapping shielding films. It was Then, the gap became larger toward the upper side of the shielding film. In addition, a gap has also formed between the showcase side plate portion and the shielding film surface when viewed from the front direction.

The present invention is intended to achieve a further energy saving effect by further eliminating the above-mentioned gap. The purpose of the present invention is to provide a gap between the shielding curtains of adjacent night covers, a shielding film and a showcase. By eliminating the gap between the side plates, it prevents the outside air from being sucked into the refrigerator,
Another object of the present invention is to provide a good-looking open showcase by improving the energy-saving efficiency and providing a decorative cover for hiding the night cover body during storage.

[0009]

In order to achieve the above object, in the present invention, an air curtain of cold air is formed in a front opening of a casing from a cool air blowout port at an upper part toward a cool air intake port at a lower part, In an open showcase that cools the products displayed in the refrigerator, the night covers that are adjacent to each other among the plurality of night covers that cover the front of the air curtain when not in business are staggered, and when the night covers are pulled out. A pressing member for pressing one of the shielding films against the other shielding film so that the ends of the adjacent shielding curtains can be overlapped with each other and the overlapping portions of the shielding films can contact each other without a gap. It is characterized by the provision of.

The pressing member against the shielding film of the present invention can be provided inside the decorative cover that covers the front surface of the night cover, or the decorative cover itself can also be used as the pressing member. Further, it is preferable that the rail portion at the lower end of the night cover is formed shorter than the width dimension of the shielding film so that the rail portions do not contact each other when the ends of the shielding film are overlapped with each other. Further, it is preferable that the side plate of the showcase using the night cover is provided with a contact surface with the night cover shielding film surface in the trim at the front end of the side plate windshield, because the invasion of the outside air can be further prevented. It should be noted that the material for the shielding curtain of the night cover is a film-shaped transparent vinyl body or an aluminum woven cloth having a heat insulating and ventilation effect, so that a close overlap is ensured and the suction phenomenon of outside air into the chamber is prevented as much as possible. It is preferable above.

[0011]

[Operation] By adopting the above configuration, the present invention eliminates the gap between the shielding curtains of the night cover when viewed from the front and side of the showcase, and between the shielding film and the side plate when viewed from the front. Since there is no gap, the invasion of outside air into the chamber is almost completely blocked, and the energy saving efficiency is further improved. In addition, the dew condensation in the refrigerator due to the intrusion of a small amount of outside air is almost eliminated.
