Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention has a so-called multi-stage refrigerated open showcase which has a product take-out opening on the front surface and is formed inside the storey behind this opening. It relates to a lighting device.

2. Description of the Related Art A multi-stage refrigerated open showcase is already widely used and known. In this refrigerated showcase, shelves are provided in the refrigerator to divide the inside of the refrigerator into upper and lower stages, and a large number of commodities are stored in multiple stages and displayed effectively. This product is cooled by a refrigerator and refrigerated. At the front end of each of the shelves and on the ceiling of the main body case, straight tube-type fluorescent lamps are installed laterally at every step to illuminate the goods below them.

[Problems to be solved by the invention]

By the way, in a conventional refrigerated open showcase, a large number of fluorescent lamps corresponding to the number of stages in the refrigerator are installed. Therefore, the amount of heat generated by the fluorescent lamps increases as the number of stages in the refrigerator increases, and there is a problem that the capacity of the refrigeration apparatus needs to be increased in order to cool the refrigerator to a predetermined temperature, and the power consumption increases.

This invention can reduce the number of fluorescent lamps installed,
Further, it is an object of the present invention to provide a refrigerated open showcase interior lighting device which can solve the above problem without increasing the number of fluorescent lamps even if the number of stages in the interior is increased.

[Means for solving the problem]

In order to achieve the above object, according to the present invention, a refrigerator is formed in a substantially box-shaped main body case having a product take-out opening on a front surface, and goods are displayed and refrigerated in multiple stages in the refrigerator. In the open showcase, a mounting member is provided on the front end surfaces of the left and right side plates of the main body case, a straight tube-type fluorescent lamp is vertically installed through the mounting member, and a long sliding hole is provided in the mounting member. The fluorescent lamp is configured to be slidable in the left-right direction.

[Action]

According to the above means, since the interior of the refrigerator is illuminated from the lateral direction,
Regardless of the number of stages in the refrigerator, it is sufficient to install fluorescent lamps that fill the upper and lower ends of the refrigerator. Therefore, radiant heat to the inside of the refrigerator is extremely reduced.

Moreover, by using the long holes, the illumination of the product is enhanced when the product is illuminated, and when the product is replenished, the front inside the refrigerator is widely opened to facilitate the refilling operation.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. In the figure, 1 is a box-shaped main body case having an opening 1a on the front surface, and 2 is a side plate constituting left and right walls of the main body case 1. A window is provided in a part of the side plate 2, and a glass 22 is fitted into the window with the fixing frame 21 fixing the four sides to the side plate. The main body case 1 has an interior 3 formed at the back of the opening 1a, and the interior 3 is partitioned by a shelf 4 into upper and lower tiers.

Reference numeral 5 denotes an interior lighting device, in which a support plate 57 to which a step screw 56 is screwed is fixed to the fixed frame 21, and a left and right long hole 58 guided by the step screw 56 is attached to a vertically extending mounting plate 51. Is provided. The reflection cover 52 and the lamp cover 55 are attached to the mounting plate 51.
Attached to Reference numeral 6 denotes a straight tube fluorescent lamp which is supported by a lamp holder (not shown) and illuminates the interior 3 in the vertical direction.

In the above-described configuration, the products are displayed on the shelf 4 and the bottom plate in the refrigerator 3 and cooled by a freezing device (not shown). On the other hand, in the interior lighting device 5, a fluorescent lamp 6 held on the front end face of the side plate 2 of the main body case 1 uniformly illuminates the interior 3 from the left, right and front of the interior. Therefore, the goods on the inner bottom plate and each shelf 4 are illuminated for easy viewing. In addition, only one fluorescent lamp 6 is required on each of the right and left sides, so that the power consumption and the amount of heat generated are extremely small.
It is not necessary to increase the number of fluorescent lamps 6 even if the number of display stages of products is increased by increasing the number of fluorescent lamps.

Further, by utilizing the long hole 58, the fluorescent lamp 6 is moved toward the center of the refrigerator for product lighting to enhance the lighting of the product, and the fluorescent lamp 6 is moved outward when refilling the product, so that the front surface of the refrigerator is widened. This has the advantage of being open to facilitate refilling operations.

〔The invention's effect〕

According to the present invention, in the refrigerated open showcase in which the interior is formed in a substantially box-shaped main case having a product take-out opening on the front surface, and the products are refrigerated in multiple stages in the interior, A mounting member is provided on the front end surface of the left and right side plates of the straight tube type fluorescent lamp is vertically installed through this mounting member, and a long sliding hole is provided in this mounting member so that the fluorescent lamp can be slid in the left and right direction. , It is sufficient to use a small number of fluorescent lamps to illuminate the interior of the refrigerator, and there is no need to increase the number of fluorescent lamps even if additional shelves in the refrigerator are added, and there is no increase in the amount of heat generated by the fluorescent lamps. There is no need to increase the refrigeration capacity.

In addition, by using the long holes to slide the fluorescent lamp in the left and right direction, the lighting of the product is enhanced when the product is illuminated, and the front of the refrigerator is opened widely when the product is refilled, facilitating the refilling operation. Can be
