In FIG. 8, 1 is a heat insulating box made of urethane foam, 2 is a shade made of a translucent plastic plate, 3 is used to illuminate the inside of the freezer / refrigerated showcase, and the outside is also illuminated through the shade 2. It is a fluorescent lamp. 4 is a reflector for reflecting the light of the fluorescent lamp 3, 5 is a cold air outlet for discharging cold air into the cabinet, 6 is an inlet for sucking in air, 7 is equipped with a cooler inside, and from the inlet 6 This is a cold air passage for cooling the sucked air and sending it to the cold air discharge port 5. 8 is a commodity display shelf, 9 is a base in which a cooling unit and electrical components are housed, and 10 is a kick plate that covers the front of the base 9.
[0003]
In order to turn on the fluorescent lamp 3, a ballast is necessary. In recent years, an electronic ballast using an inverter has been used as the ballast. If an electronic ballast is used, the flickering of the fluorescent lamp is almost eliminated and energy saving is achieved. However, the size is larger than that of a conventional coil ballast, and a large storage space is required. Therefore, in the conventional freezing and refrigeration showcase, the electronic ballast is usually housed in a box and housed inside the kick plate 10.
[0004]
In such a showcase, it is necessary to repair the electronic ballast when it fails. At that time, after the kick plate 10 at the lower end of the showcase is removed, the box containing the electronic ballast housing is pulled out. Although work will be performed, it is necessary to perform such work in a bent posture, and the work is difficult. In addition, since the fluorescent lamp 3 is located at the upper part of the showcase, if the electronic ballast is provided at the lower end of the showcase, the wiring from the electronic ballast to the fluorescent lamp 3 becomes long and the cost increases.
[0005]
Therefore, it is conceivable to store the ballast storage box in the space above the reflector 4 on the fluorescent lamp 3 at the upper end on the front side of the showcase. FIG. 9 is a view showing an example of mounting the ballast storage box on the reflector. In FIG. 9, reference numerals 1 to 7 correspond to those in FIG. 8, 11 is in front of the top plate, 12 is after the top plate, 13 is a stay for supporting the front 11 of the top plate and the rear 12 of the top plate, 14 is Fluorescent lamp mounting bracket, 15 is a discharge port support, 16 reflector fixing bracket, 17 ballast storage box, 20 is a shade stay, 33 is a front cover, and 34 is a screw for fixing the front cover 33.
[0006]
A ballast storage box 17 is fixed with screws on the back side of the ceiling surface of the reflector 4 on the upper side of the fluorescent lamp 3. Further, a box insertion hole is provided in a portion of the upper portion of the reflector 4 that is inclined obliquely downward and located in front of the ballast storage box 17. The box insertion hole is closed with a front cover 33 so that the box insertion hole cannot be seen from the front side of the shade 2. The front cover 33 is fixed to an inclined portion of the upper portion of the reflector 4 by screwing a screw 34 from the front side.
[0007]
When the electronic ballast breaks down, the shade 2 and the top 11 are removed, the screws 34 are removed, the front cover 33 is removed, and the screws fixing the ballast storage box 17 to the reflector 4 are removed. The ballast storage box 17 can be pulled out to the front side through the box insertion hole.
[0008]
By doing so, when the electronic ballast is repaired, the ballast storage box 17 can be pulled out to the front side of the showcase and the repair work can be performed.
[0009]
[Problems to be solved by the invention]
However, in such a refrigerated / refrigerated showcase, since the screw 34 is immediately behind the translucent shade 2, there is a problem that the head of the screw is visible from the front side of the shade 2 and is obstructive.
[0010]
An object of the present invention is to solve such a problem and to prevent a screw for fixing a front cover that closes a box insertion hole from being visible from the front side of the shade 2.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the freezing / refrigerating showcase of the present invention has a heat insulating box that has an opening for putting in and out a product on the front surface and can display the product inside, and a front upper end of the heat insulating box. A light-transmitting shade provided in the lateral direction so as to cover the part, a reflector provided on the rear side of the shade, a fluorescent lamp provided in the horizontal direction between the shade and the reflector, and above the fluorescent lamp A freezer / refrigerator showcase provided with a ballast for the fluorescent lamp provided in the reflector, wherein the reflector includes an upper inclined portion inclined obliquely downward, a ceiling portion located on the fluorescent lamp, and It consists of a vertical rear part located on the rear side of the fluorescent lamp, and a box insertion hole is provided in the upper inclined part, and a ballast storage box containing the stabilizer is fixed to the rear side of the box insertion hole, Front cover covering the box insertion hole The top, the engagement piece provided to protrude on both right and left sides, through the engaging piece to the box insertion hole to engage the opposite side edges of the box insertion hole, formed by bending a lower portion of the front cover to the rear The contact plate is screwed to the ceiling of the reflector from below.
