DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerated showcase, and more particularly, to a refrigerated showcase having an improved internal structure for guiding illuminating light to the whole area of a refrigerator.

[0002]

2. Description of the Related Art Refrigerated showcases are used to refrigerate foodstuffs and the like in a cooled warehouse and display them to customers.
In consideration of cooling efficiency, a cooler, that is, a refrigeration evaporator is provided on the ceiling. On the other hand, an illumination lamp for illuminating the exhibit is also provided above the front part. This is a simple conceptual diagram in FIG.
The display shelf 3 for placing refrigerated foodstuffs and the like is provided in the case body frame 1 filled with the heat insulating material so as to extend in the horizontal direction. An evaporator 5 is provided. There is a possibility that the air in the refrigerator contacts the surface of the evaporator 5 and forms dew, which collects and drops. For this reason, a condensation tray 7 is provided below the evaporator 5 to receive falling water droplets. The front surface of the body frame 1 is made of a transparent glass 9, and an illuminating light 11 such as a fluorescent light is provided above the transparent glass 9 to illuminate refrigerated food items through the glass 9 to enhance the display effect. The display characters of the refrigerated showcase are illuminated from behind. In this way, the refrigerated showcase is attracted.

[0003]

In the refrigerated showcase of the conventional structure as described above, in order to increase the exhibition space while having sufficient cooling capacity, the evaporator must be short and have a large horizontal area. And Therefore, the condensation tray must be large, and partially blocks the light rays R from the illuminating lamp 11, and the back of the display shelf 3 is a blind spot. Therefore, in order to illuminate the entire area of the display shelf, a separate lighting device is required, but since a waterproof seal and the like are required, the structure becomes complicated and the cost is disadvantageous. An object of the present invention is to provide a refrigerated showcase having a structure in which light from a single light or a lighting device reaches the entire exhibition space without using an additional light or device. .

[0004]

SUMMARY OF THE INVENTION A refrigerated showcase according to the present invention comprises a refrigerator, in which an evaporator is provided below a ceiling in a refrigerator, and an illuminating lamp is provided on an upper front part of the refrigerator main body. A plurality of inclined traversing plates having a gutter-shaped portion are disposed horizontally apart from each other below the evaporator to serve as a dew receiving member, and the inclination angle of the inclined traversing plate is determined by the angle of incidence of a light beam from an illumination lamp. The light from the illuminating lamp is made substantially equal so that it travels through the gap between the plurality of inclined traversing plates in the refrigerator. Preferably, the cover is hung from the ceiling between the illumination lamp and the evaporator, and a slit is provided in the cover to communicate with the optical path between the inclined traversing plates.

[0005]

In the above construction, the water drops dropped from the evaporator fall on the upper side surface of the inclined traversing plate, flow into the gutter-like portion, are collected and discharged. Therefore, water drops do not fall on the display refrigerator. Then, the light beam emitted from the illuminating lamp passes through the gap between the traversing plates along the inclined traversing plate, passes through the back side of the dew receiving member, reaches the interior of the refrigerator, and illuminates the portion.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, the refrigerated showcase 20
There is a machine room 21 below and a refrigerator display room 23 (hereinafter also referred to as a display room) above. Although not described in detail because it is a well-known one, the machine room 21 is provided with a refrigeration-type refrigerant compressor, a condenser, a condensing fan motor, and the like. The main body frame 25 that defines the display room 23 is appropriately provided with heat insulating materials 25a and 25a.
5b is filled to form a heat insulating box structure, and a windshield 27 is provided on the front surface. Although the windshield 27 is shown as a single glass plate in the figure, it is preferably configured as a double-glazed glass having a heat insulating function. A sliding door-type glass 29 is provided on the rear surface, and is used for taking in and out of refrigerated goods.

An evaporator 31 which is a part of the above-mentioned refrigerating system is provided on the ceiling of the display room 23, and a horizontal louver-shaped dew receiving member, that is, a drain pan 33 is provided below the evaporator 31. On the other hand, an illumination lamp, that is, a fluorescent lamp 35 is provided on the front surface of the upper end portion of the windshield 27, and a plastic cover 37 covering the illumination lamp 35 is illuminated from behind, and appropriate display characters (not shown) written on the surface are projected. It is. At the center of the refrigerator, a display shelf or shelf 39 for storing refrigerated items is provided extending in the horizontal direction.

Returning again to the drain pan 33, the inclined traversing plates 33a constituting the same extend parallel to each other in the lateral direction at intervals. Each of the at least two inclined traversing plates 33a on the fluorescent lamp 35 side forms a gutter-like portion 33b by bending the lower end of the main body upward at substantially right angles with respect to the main body, and forms a gutter-like portion 33b above the main body. The ridge 33c formed by bending the upper end of the main body of the traversing plate 33a substantially downward at a right angle with respect to the main body is positioned so as to overlap on the horizontal projection plane. Although not shown, each trough 33b is preferably connected to a drainage system which may have a known structure. And the fluorescent light 35 into the refrigerator
The incident angle α of the light R from the tilting plate 33a
And the lengths of the upper end and the lower end of the adjacent inclined transverse plate 33a are selected so as not to obstruct the passage of the light R.

In the above structure, in the evaporator 31, heat is taken from the surrounding air to evaporate the internal refrigerant. As a result, dew condensation occurs on the surface of the evaporator 31, and the evaporator 31 collects and falls as water drops. This falling water droplet must be drain pan 33
Falls on the inclined surface of the inclined traversing plate 33a, and is collected and discharged by the gutter-like portion 33b. The light R from the fluorescent lamp 35 passes through the gap between the adjacent inclined transverse plates 33a, is reflected on the back surface, and brightens the entire area of the shelf 39. That is, all the refrigerated display items on the shelf 39 are illuminated,
There is no shadow.

FIG. 2 shows a modified embodiment in which a cover 41 for concealing the evaporator and the drain pan is suspended from the front in the above-described embodiment, but the other configuration is the same as that described above. And the description is omitted. Cover 4
1 is vertically installed from the ceiling in the refrigerator between the evaporator 31 and the drain pan 33 and the fluorescent lamp 35, and has a slit 41a formed so as not to hinder the straight movement of the light R. Cover 41
It is preferable that the lower end portion 41b is inclined at the same angle as the inclined traversing plate toward the back side of the compartment so as not to narrow the field of view of the display room 23 or obstruct the lighting. Accordingly, the light from the fluorescent lamp 35 travels through the gap between the slit 41a and the inclined traversing plate 33a, and illuminates the entire area above the shelf 39 as in the first embodiment.

Although the embodiment of the present invention has been described with respect to a drain pan having four inclined transverse plates, the present invention is not limited to this embodiment, and various modifications are possible. For example, the number of the inclined traversing plates may be any number as long as it is two or more, and the lower end portion 133b of the second inclined traversing plate 133a may be formed as shown in FIGS. In the figure, the shape extends like the conventional drain pan by extending greatly to the right side, or in a position where the upper end of the second inclined traversing plate 233a overlaps the lower end of the first one, without being curved downward and straight. May be terminated.

[0012]

As described above, according to the present invention,
The dew receiving member below the evaporator was formed in a horizontal louver shape, and the angle of inclination of the inclined traversing plate was substantially equal to the angle of incidence of the light of the illuminating lamp. It is possible to effectively illuminate the entire exhibition area without blocking the gap.
