Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open showcase installed in a convenience store or the like for refrigerating and freezing products for sale in a storage room having a front opening, and more particularly to a mirror of this showcase. With respect to the side plate.

[0002]

2. Description of the Related Art In this type of open showcase, as disclosed in Japanese Utility Model Publication No. 55-54372, a mirror is attached to the inner surface of the side wall of the showcase to improve the effect of exhibiting the product for sale. Various configurations are widespread.

Here, the side plate is formed of a heat insulating material and has a suitable thickness so as to obtain a sufficient heat insulating effect. Especially when a mirror is attached, the side plate has an overall thickness of, for example, 40 mm in order to compensate for the decrease in heat insulation performance due to the presence of the mirror.
It is fairly thick and moderate.

By the way, due to recent downsizing of stores and the like, it has been demanded that showcases can be more effectively arranged in a row in a store. In order to realize this, it is conceivable to use a showcase with a thin side plate.

However, if the side plate is made thinner, the heat insulation performance is deteriorated and the dew-proof performance is insufficient.
This problem becomes even more pronounced with side plates with mirrors, so simply reducing the thickness of the side plates will not prevent condensation from forming an open showcase that can satisfy the needs of consumers. .

The present invention has been made in view of the above points, and by installing a heater on the outer surface material of the side plate on the rear surface of the mirror, it is possible to sufficiently prevent dew condensation on the outer surface of the side plate and to reduce the thickness of the side plate. The goal is to provide an open showcase that can be made into a new product and that can improve store design and make effective use of floor space.

[0007]

According to the present invention, there is provided an open showcase in which a front side storage chamber formed in a main body by providing side plates on both sides is cooled by a refrigerating device provided in the main body. A side plate of an open showcase, characterized in that a mirror is attached to the side surface of the side plate in the storage chamber and a dew-proof heater is installed inside the outer surface material of the side plate so as to correspond to the mirror.

According to the present invention, the side plate of the open showcase is provided with the power outlet of the heater on the inner surface side of the side plate at a position near the raceway portion extending horizontally behind the lower front part of the open showcase. Is.

[0009]

By attaching a mirror to the inner surface, a dew-proof heater is installed inside the outer surface material of the side plate of the side of the storage chamber where there is a concern that the heat insulation performance may be degraded. The surface of the side plate is kept at a certain temperature. Therefore, even if the side plate of the open showcase is thick as in the conventional case, even if the side plate is thin, it is possible to configure the open showcase capable of sufficiently preventing dew condensation.

By arranging the heater in the side plate, it is possible to reduce the thickness of the side plate having a mirror, and it is possible to effectively install the open showcase in a small store.

Further, the power outlet of the heater is formed inside the lower part of the side plate, and the connection with the power source can be easily made at a position near the raceway part on the front lower part of the showcase where a power socket for power supply is provided. In addition, it can be performed reliably and can be disposed so as not to be exposed to the outside.

EXAMPLES Examples of the present invention will be described below with reference to screens.

In each figure, 1 is an open showcase having a plurality of shelves 4 in a storage room 3 having an opening 2 on the front, and a plurality of shelves 4 are horizontally installed in a store such as a convenience store.

The open showcase 1 includes a main body 1A having a heat insulating structure in which an upper wall, a lower wall and a back wall are integrally formed,
A machine room 5 is formed in the lower part of the main body 1A and houses a compressor, a condenser, a cooling fan for the condenser, etc., and a partition plate 6 is installed inside the main body 1A at a required interval. A cold air passage 7 is formed between the main body 1A and the main body 1A.

A cooler 8 is arranged in the cold air passage 7, a cold air circulation fan 9 is arranged in a bottom area 7b of the cold air passage 7, and an opening 2 of the storage chamber 3 surrounded by a partition plate 6 is provided. A cold air outlet 11 and a cold air inlet 12 are provided in the upper and lower parts of the so as to extend laterally.

The cool air that has exchanged heat with the cooler 8 is blown out from the cool air outlet 11 by the cool air circulation fan 9 and forms an air curtain of cool air toward the cool air suction port 12 to insulate the storage chamber 3 from the outside world to a low temperature. keep.

Here, a side plate 14 made of a heat insulating material 13 is attached and fixed to the open showcase 1 installed at the end so as to close the side opening.

A mirror 15 having substantially the same size as the inner surface opening is attached and fixed to the inner surface side of the side plate 14 so that the product on the shelf 4 is displayed and the display effect is enhanced.

Reference numerals 16a and 16b are provided above and below the inner surface of the side plate 14, and are formed with inwardly open grooves. The upper and lower ends of the rear edge of the mirror 15 are formed in these grooves. Is a mirror support part for inserting and holding each of them.

The rear ends of the mirror support portions 16a, 16a are
As shown in FIG. 4, the mirror 1 is inserted into and held in the b plate and is arranged along the inner surface of the side plate 14 from the front side.
The mirror 15 is attached and fixed to the side plate 14 by being fitted so as to include both 5 and the side plate 14 and screwed.

The side plate 14 to which the mirror 15 is attached is composed of an outer side plate 18 and an inner side plate 19, and a urethane foam heat insulating material 21 filled between these two plates 18, 19.

In the heat insulating material 21, a dew-proof heater 32 is made to correspond to the mirror 15 as shown in FIGS.
It is arranged so as to be in contact with 8.

A power outlet 24 for the heater 22 is provided on the inner surface of the lower portion of the side plate 14.

In creating the power outlet 24,
As shown in FIG. 5, the heat insulating material 21 is prevented from entering the relevant portion, and the outlet passage 25 of the heater 22 and the heater 2 are prevented.
The partition plate 27 in which the second storage space 26 is formed is arranged between the inner plate 19 and the outer plate 18, and the inner plate 19 is also provided with an extraction hole 29 communicating with the storage space 26 of the partition plate 27. , The heat insulating material 2 between the inner plate 19 and the outer plate 18.
By foaming and filling 1 with, it is formed integrally with the side plate 14.

The power outlet 24 is provided at a position slightly above the raceway 30 arranged in the lower part of the front of the open showcase, as shown in FIG.
