Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lighting device in a frozen and refrigerated food display case.

[Conventional technology]

A front opening of a frozen and refrigerated food display case is usually equipped with an air curtain that generates cold air in order to make it convenient to take in and take out the displayed food and to improve the display effect.

In conventional display cases of this kind, illumination lights such as fluorescent lights are installed on the lower surface of the top plate of the display food storage box and at each front end of the lower surface of the shelf board to illuminate the food below. A cover was installed just in front of the lighting to prevent the direct light from the lighting from shining directly into the eyes of customers.

However, since some outside air enters the vicinity of the front opening of the air curtain type frozen and refrigerated food display case, the temperature becomes higher than that at the rear of the case.

Furthermore, the temperature of the food directly under the lighting lamp becomes higher than the surrounding cold temperature due to the radiant heat of the lighting lamp.

Therefore, in conventional display cases, the temperature of the food at the front of the shelf is considerably higher than that at the rear, and if you try to lower the temperature of the food at the front to a predetermined value, the food at the rear will be overcooled. At the same time, the load on the cooling device increases, leading to an increase in power consumption.

In order to solve the above problem, the lower surface of the shelf is made a reflective surface, and the illumination of the upper surface of the shelf is made as average as possible by using the direct light from the lighting lamp installed behind it and the reflected light from the reflective surface. Attempts have been made to make this possible (see, for example, Japanese Utility Model Application Publication No. 153991/1983).

[Problem that the invention attempts to solve]

In the conventional type, the reflective surface is fixed, so even if it was attempted to change the illumination intensity at the front and rear of the shelf depending on the type and shape of the food, it was impossible to do so.

An object of the present invention is to provide a lighting device for a frozen and refrigerated food display case that can meet such demands using simple means.

[Means for solving problems]

According to the present invention, a small receiving shelf with a plurality of horizontal pieces is provided at the front end of the lower surface of the top plate of the food storage box, and the front end of the reflector plate whose rear end is latched to the rear end of the lower surface of the shelf board. The above object is achieved by locking onto a suitable horizontal piece of the receiving shelf and arranging a forward-facing illumination light at the rear lower part of the reflector.

[Effect]

The front end of the reflector can be supported with different horizontal pieces.

〔Example〕

A food storage box 3 with a front opening similar to the insulation box 1 is fixedly installed inside the insulation box 1 with a front opening in a frozen and refrigerated food display case via a cold air circulation path 2. An appropriate number of shelf boards 4 whose portions are slightly inclined downward are installed.

At the upper and lower ends of the front opening of the display case in the cold air circulation path 2, a cold air outlet 5 and an inlet 6 are provided, respectively, and a blower 7 and a cooling device ( An evaporator 8 (not shown) is installed.

The cold air inside the display case is cooled by the blower 7 while passing through the evaporator 8, as shown by the arrow, and is ejected from the jet port 5 and sucked into the suction port 6, and the cold air is delivered to the opening of the display case. curtain 9
is formed, circulates through the circulation path 2, and cools the inside of the storage box 3.

A small receiving shelf 10 is provided at the front end of the lower surface of the shelf board 4. The receiving shelf 10 has a plurality of horizontal pieces 12 with a small depth on the rear surface of a low vertical piece 11, and between the shelf board 4 and the horizontal piece 12 directly below it, and between the adjacent horizontal pieces 12, A wave-curved leaf spring 13 and other spring materials are sandwiched.

At the rear end of the lower surface of the shelf board 4, there is a receiving bracket 1 that opens in the front.
4 is installed vertically.

A reflective plate 15 whose depth is slightly smaller than the distance between the rear ends of the receiving shelf 10 and the receiving metal fitting 14 is mounted on an appropriate horizontal piece 12 of the receiving shelf 10 and the receiving metal fitting 14, tilting forward and downward. The front end is clamped by a leaf spring 13.

An illumination light 16 is installed in a forward facing horizontal groove 17 provided immediately below the rear end of each shelf board 4 on the rear plate 3b of the storage box 3.

The food on the shelf board 4 is placed on the reflective plate 15 as shown by the arrow.
The reflected light from the illuminating lamp 16 and the direct light from the illuminating lamp 16 provide average illumination.

[Effect of idea]

By locking the front end of the reflector to different horizontal pieces, the angle of inclination of the reflector can be changed, and the degree of illumination at the front and rear can be adjusted depending on the shape and type of food displayed. can be adjusted optimally.
