Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerated showcase in which a front opening is partitioned into left and right sides by struts, and a horizontally elongated light source is provided at the upper end of each opening. The objective is to maximize the effective internal volume of the storage room by installing a shade plate.

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a refrigerated showcase whose main body is composed of a heat insulating wall 2 with a front opening 3, and a lower part at the front end of the upper wall at an appropriate distance from the inner wall of the heat insulating wall. A storage room 5 and a cold air passage 6 in which a cooler 7 and a blower 8 are installed are formed by disposing an inverted L-shaped partition plate 4 having a bent side 4a extending to A machine room 9 is formed in which a compressor 10, a condenser 11, and a blower 12, which together with the container constitute a refrigeration cycle, are installed.

Reference numeral 13 denotes a column that stands in the center of the front opening and divides the opening into left and right parts; 14 and 14 denote a transparent door body with a gasket 15 that is rotatably pivoted to the main body and closes each of the front openings so as to be openable and closable; It is. Reference numeral 16 denotes a horizontally elongated light source 1 such as a fluorescent light, which is provided along the upper end of each front opening, that is, at the upper front of the storage chamber 5, and located inside the transparent door bodies 14, 14.
This is a translucent shade plate that covers the pillars 7 and 17, and is made of synthetic resin and has a substantially U-shaped longitudinal section, integrally forming an outer surface 16a, a bottom surface 16b, and an inner surface 16c, as shown in FIGS. 3 and 4. Outer surface 16a facing 13) A notch 18 cut out in the center of the bottom surface 16b and fitted into the upper end of the support column 13 from the rear.
The flange portion 16d at one end is engaged with the stepped portion 21a of the connector 21 that connects the inner box 19 and the outer box 20 in an adiabatic manner, and the mounting portion 16e at the other end is attached to the inner box 19 by screws 22. It can be attached by stopping.

Reference numeral 23 denotes a cold air outlet formed by the inner surface 16c of the shade plate 16 and the bent side 4a of the partition plate when the shade plate 16 is attached. , 14.

Reference numeral 24 denotes a suction port formed at the lower end of the partition plate 4, which guides the cold air that has passed through the storage chamber 5 to the cooler 7.

According to the above configuration, the light source bodies 17, 17 and the translucent shade plate 16 covering the light source bodies are provided at the upper front surface of the storage chamber 5, and the transparent door body that closes the front opening 3 in a freely openable and closable manner. 14, 14, the illumination from the light sources 17, 17 passes through the shade plate 16 and reaches directly into the storage chamber 5, so the illumination effect in the storage chamber 5 is good. Also, by installing the shade plate 16,
Since it is possible to cover the light source bodies 17, 17 disposed with the pillar 13 as a boundary and simultaneously form the air outlet 23 which rectifies the cold air and blows out along the transparent door bodies 14, 14, each light source body 17, 1
Parts such as individual shade plates covering the respective parts 7 and parts forming the outer part of the air outlet 23 are not required, and the shade plate 16 can be used effectively, and at the same time, the installation work is simplified and the number of parts can be reduced.

Also, the outer surface 16a of the shade plate 16 facing the support 13
1. Since a notch 18 is formed in the center of the bottom surface 16b to fit into the support column 13, even if the support column 13 is installed in the front opening 3, the shade plate 16 can be removed by the size of the cutout 18. By attaching the air outlet 23 close to the front end of the upper wall of the heat insulating wall 2, the effective internal volume of the limited storage chamber 5 can be maximized, and the light source body 17, 17 and the bent side 4a. By increasing the distance, the illumination angle of the light sources 17, 17 can be increased, and since the inner surface 16c that guides cold air is seamless, it is possible to prevent cold air from entering into the shade plate 16. . FIG. 5 shows an embodiment of the present invention, in which the inner surface 16c of the translucent sheet plate 16 is made thicker than the other surfaces, and the inner surface 16c that guides cold air in this way is thicker than the other surfaces. By increasing the thickness, even when low-temperature cold air is circulated, heat transfer from the cold air to the light source bodies 17, 17 is reduced, and a decrease in illuminance of the light source bodies 17, 17 due to this heat transfer is prevented. It can be prevented. As described above, the present invention comprises a main body composed of a heat insulating wall with a front opening, and a partition plate having a bent side extending downward is disposed at the front end of the upper wall at an appropriate distance from the inner wall of the heat insulating wall. A storage room and a cold air passage where a cooler and blower are installed are formed. Supports are erected to divide the front opening into left and right sides, and transparent doors that can be opened and closed according to the number of openings are installed. One horizontally elongated light source body is provided at the front upper part of the storage chamber, which is the upper end, and consists of an outer surface, a bottom surface, and an inner surface, and the outer surface facing the support column and a part of the bottom surface have a notch that fits into the upper end of the support column. A translucent shade plate formed by a transparent shade plate is disposed at the upper front of the storage chamber so as to cover each light source, and cool air is blown by the inner surface of the shade plate and the bent side of the partition plate. Since it is characterized by forming an outlet, the light source provided at the upper front of the storage room can be protected from cold air by the shade plate, preventing a decrease in the illuminance of the light source, and the illumination of the light source can be The light passes through and reaches the storage room directly, improving the illumination effect of the storage room.Also, the number of parts can be reduced by using a shade plate that covers multiple light sources at the same time as a part that forms the air outlet. Even if a post is installed in the opening, the shade plate can be attached close to the transparent door body by fitting the notch to the post, and the air outlet can be formed close to the front end of the upper wall of the insulation wall. The effective internal volume of the limited storage chamber can be maximized, and the illumination angle of the light source can be increased.
