DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open showcase which is installed in a convenience store or the like, and in which a sales product is refrigerated and frozen for display and sale in a storage room with an open front, and in particular, an anti-dew heater is provided. The present invention relates to a side plate of a showcase provided with a mirror arranged on the back.

[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 so as to improve the display effect of products for sale. Configuration is widespread.

[0003] Here, the side plates are formed of a heat insulating material and have a suitable thickness so as to obtain a sufficient heat insulating effect. Especially when a mirror is mounted, 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 quite thick.

By the way, due to recent downsizing of stores, it has been demanded that more and more showcases can be successively installed in the store. To realize this, it is conceivable to use a showcase in which the side plates are thinned.

[0004] However, when the thickness of the entire side plate is reduced, there is a problem that the heat insulating performance is reduced and the dew-proofing performance is insufficient.
This problem is even more pronounced with mirrored side panels, so simply reducing the thickness of the side panels will not prevent the formation of dew condensation, and cannot be an open showcase that can meet the needs of consumers. . In order to remove the fogging of the mirror, a heater for dew prevention is provided on the back of the mirror, but the power supply outlet for supplying power to this heater is easily connected to the power cord, and it does not stand out outside. It is also desirable to pay attention to the provision in a convenient location.

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and by installing a heater on an outer surface material of a side plate on the back surface of a mirror, it is possible to sufficiently prevent dew condensation on the outer surface of the side plate and to make the side plate thinner. In addition, a power outlet for supplying power to the dew-proof heater is provided at the back of the railway of the showcase to hide its presence, thereby improving store design and achieving effective use of floor space. The purpose is to provide an open showcase.

[0007]

SUMMARY OF THE INVENTION The present invention is directed to an open showcase in which a storage room having side plates provided on both sides and an opening at the front is cooled by a refrigerating device. While installing the mirror, a dew-proof heater is installed inside the outer surface material of the side plate so as to correspond to the mirror, and the power supply outlet of the heater extends horizontally behind the front lower part of the open showcase. A side plate of an open showcase, wherein the side plate is provided on an inner surface side of the side plate at a position close to an existing raceway portion.

[0008]

[0009]

[Function] By installing a mirror on the inner surface, a heater for dew-proofing is installed inside the outer surface material on the side plate on the side of the storage room where there is a concern that the heat insulation performance may be deteriorated. The temperature of the side plate surface is set to a certain level. Therefore, it is possible to form an open showcase in which dew condensation can be sufficiently prevented even when the thickness of the side plate of the open showcase is changed from a conventional thick plate to a thin side plate.

[0010] By disposing the heater in the side plate, it is possible to reduce the thickness of the side plate having a mirror, thereby enabling an effective installation of an open showcase in a small store.

The power supply outlet of the heater is formed inside the lower portion of the side plate, and the connection to the power supply is easily made at a position close to the raceway portion on the lower front surface of the showcase provided with a power supply socket for power supply. It can be performed reliably and can be disposed so as not to be exposed to the outside.
