Abstract

PURPOSE: To reduce the rise of temperature of a stabilizer by attaching the stabilizer of the lighting circuit of a fluorescent tube to the inner box which cools the inside of a box to control the temperature of commodities to be sold. CONSTITUTION: A first chamber A out of first to third chambers A to C divided by partitions 7 is exclusively cooled, and second and third chambers B and C are cooled or warmed by switching. A stabilizer 10 of the lighting circuit of a fluorescent tube 9 is attached to the outside surface of an inner door 6b with a bracket 11 between them so as to face the first chamber A which is exclusively cooled. The bracket 11 is formed by sheet metal processing of a metal having a high heat conductivity. By this constitution, the heat of the stabilizer 10 is radiated to the inner door 6b through the bracket 11 having a high heat conductivity to reduce the rise or temperature. Though dew condensation is brought about on the outside surface of the inner door 6b by cooling of the inside, water due to dew condensation is not stuck to the stabilizer 10 because of flowing down to a conduit part 11a.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for a vending machine.

[0002]

2. Description of the Related Art A vending machine for canned beverages is constructed as shown in FIG. The vending machine itself has an outer case 1
And an outer door 2 that closes the front opening of the outer case 1. A middle door 3 is attached to the rear surface of the outer door 2, and a customer service section such as a product selection button group and a product display shelf 4 is formed between the outer door 2 and the middle door 3. 5 is a transparent window material.

Reference numeral 6 denotes an inner box having a heat insulating structure, which includes an inner box body 6a and
It is configured with an inner door 6b that closes the front opening of the inner box body 6a. The inside of the inner box 6 is divided into a plurality of chambers by a partition wall 7, and a product transport device 8 is installed in each chamber. In addition, the temperature of each room is adjusted to a set temperature by a common or independent air conditioner.

A large number of fluorescent tubes 9 for illuminating the sample on the product display shelf 4 are built in between the outer door 2 and the inner door 3, and the ballast 10 of the lighting circuit of each fluorescent tube 9 is centered. It is attached to the door 3.

There is also seen that the ballast 10 is attached to the inside of the outer door 2.

[0006]

In the case of a vending machine installed in direct sunlight in the summer, the surface temperature of the outer door 2 rises extremely, and the temperature of the ballast 10 is limited to the specified limit temperature. There is a problem that exceeds.

An object of the present invention is to provide a lighting device capable of reducing the temperature rise of the ballast.

[0008]

The lighting device of the present invention has an inner box for cooling the inside of the refrigerator to control the temperature of the sold product, and illuminates the customer service section by lighting the built-in fluorescent tube. In the above, the ballast of the lighting circuit of the fluorescent tube is attached to the inner box.

[0009]

According to this structure, the surface temperature of the inner box whose inside is cooled is low. The heat of the ballast is radiated to the inner box to reduce the temperature rise.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vending machine equipped with the lighting device of the present invention will be described below with reference to FIGS.

The components having the same functions as those of the conventional example shown in FIG. 4 will be described with the same reference numerals. Of the first chamber A, the second chamber B, and the third chamber C divided by the partition wall 7, the first chamber A is dedicated to cooling, and the second chamber B and the third chamber C are switched to cooling and heating. You can

The ballast 10 of the lighting circuit of the fluorescent tube 9 is attached to the outer surface of the inner door 6b via a bracket 11 corresponding to the first chamber A dedicated to cooling. The bracket 11 is made of a metal having good heat conduction by sheet metal working.

With this structure, the heat of the ballast 10 is radiated to the inner door 6b through the bracket 11 having good heat conduction, and the temperature rise can be reduced. Although the inner surface of the inner door 6b is cooled, dew condensation occurs,
In this embodiment, as shown in FIG. 2, a gutter portion 11a and a ballast mounting portion 11b formed below the gutter portion 11a.
The condensed water is received by the gutter 11a and flows down the gutter 11a whose left side is lowered. Therefore, no condensation water is applied to the ballast 10 located below the trough 11a.

Although the inner door 6b is mounted on the surface of the inner door 6b in the above-described embodiment, it may be mounted on other places of the inner box 6.

[0015]

As described above, according to the present invention, there is provided an automatic vending machine which has an inner box for cooling the inside of the refrigerator to control the temperature of the sold product and illuminates the customer service section by lighting the built-in fluorescent tube.
Since the ballast of the lighting circuit of the fluorescent tube is attached to the inner box, the heat of the ballast is radiated to the inner box and the temperature rise can be reduced.
