Description

[0001] The present invention relates to a vending machine with a backlight unit,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage vending machine, and more particularly, to a beverage vending machine having a backlight unit having a backlight unit formed on a door of a beverage vending machine so as to provide an image for advertisement or guidance using a light source.

Generally, in a restaurant or an office, a beverage vending machine in which a cold / hot water system is integrally installed so that coffee or various kinds of tea and beverages can be easily ingested is widely available.

In such a beverage vending machine, an operation button for selecting a beverage is operated by inserting a coin into a coin receiving portion provided in the door, thereby discharging the cup containing the beverage to the beverage discharging portion.

However, in the conventional beverage vending machine, the door having the coin input portion for inputting most coins and the operation button, which is a menu selection portion for selecting a menu, is composed of only one color, so that the appearance is monotonous and unfavorable.

Therefore, in order to solve such a problem, applicant of the present application has disclosed a drink vending machine having a backlight unit of Registration Practical Utility Model No. 20-0470365.

A conventional beverage vending machine having a backlight unit includes a body in which a material, a paper cup, and water are accommodated so as to produce coffee, beverage, tea or the like therein; A door installed on the body to open and close the front surface of the body; And a backlight unit provided in the installation space formed in the door to provide a light source to the advertisement sheet of the door, wherein the door is provided on the front surface of the body through the pivoting member and the locking member, And a drink discharge unit for discharging coffee or a paper cup containing the beverage from the beverage discharging means of the body is formed at a lower end thereof. A menu selection button for selecting the type of beverage and a display unit for displaying the selection menu are installed at the upper end And a seating part for providing the advertisement sheet and the backlight unit is formed in a concave shape at the front center part so that an image for advertising or guidance using a light source is provided.

However, in the conventional beverage vending machine having the backlight unit, the backlight unit is installed in the seating part after the concave-shaped seating part is formed outside the door.

Here, in the case of the backlight unit, the light source unit is provided on the upper portion of the seating unit, and the light guide plate is installed on the seating unit through the process of providing the light guide plate on the lower side of the light source unit. Wherein the light guide plate comprises a printed circuit board to which operation power is supplied from an operation power supply unit for supplying operation power to the components of the body and a plurality of LEDs arranged at regular intervals on the printed circuit board, A panel in which the printed circuit board of the light source unit stably contacts the contact portion and a reflective sheet attached to the back surface of the panel and reflecting the light source to be dispersed toward the front face or the light distribution pattern of the panel.

In order for the backlight unit to be formed in the concave seating portion, the light source unit must first be adhered to the upper flange of the seating portion, and then the light guide plate should be bonded to the bottom face of the seating portion. The connection for electrical connection between the printed circuit board and the operating power supply must be made.

However, in the case of the seat portion, since the operating power supply portion for supplying operating power to the printed circuit board of the light source means is formed separately at the inner side portion of the door, not the seat portion, In addition, since the work space for connecting the operating power supply unit to the printed circuit board is not secured due to the above-described structure, the work hole must be separately formed in the seating part, There is a problem that is very complicated and inconvenient.

In addition, since the light source unit and the light guide plate are bonded to the seating portion having the groove-like shape, the maintenance of the light source unit and the light guide plate must be performed by an adhesive releasing operation (force separation or pulling operation) At this time, there is a fear that the constituent parts may be damaged and maintenance is not easy.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an advertising light-transmitting cover for an advertising light through a backlight unit, which maximizes the effect of the advertising light through the backlight unit by forming an opening in the door of the beverage vending machine, And to provide a beverage vending machine having a backlight unit that can be easily assembled and easy maintenance of the unit.

Another object of the present invention is to provide a beverage vending machine having a backlight unit capable of minimizing the manufacturing cost by making the advertising sheet attached to the light-transmitting cover constitute a diffusion film.

Another object of the present invention is to provide a beverage vending machine having a backlight unit capable of maximizing illumination and reflection efficiency by allowing the inner surface of the reflector to have a high-gloss surface and a white color.

Meanwhile, the object of the present invention is not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.
