Abstract

PURPOSE:To make it unnecessary to cover a cover with heat-insulating anti- sweat material so as to simplify constitution, and in addition, to facilitate the attachment and the detachment of the cover by installing the cover to open and close a small chamber in a box. CONSTITUTION:The small chamber 5 is formed in a frame body 4 together with the frame body 4 at the time of forming an inner door 1, and a lamp 8 is fitted in the small chamber 5. The cover 7 is fitted freely attachably and detachably to the front face of the frame body 4 by being inserted into a locking groove 43 at its lower end and being pushed into the inside of a locking claw 45 at its upper end. Since the central part of this cover 7 projects by using dead space in the box where a commodity rack 10 is arranged, it never obstructs the constitution in the box such as the arrangement of the commodity tack 10, etc. Thus, by installing the cover 7 in the inside of the box in this way, the heat insulation wall outside the small chamber 5 is formed together with the heat insulation wall of the inner door 1, and the cover 7 need not be covered with the heat insulation anti-sweat material, and the constitution is simplified, and in addition, the attachment and the detachment of the cover 7 can be executed without requiring any special care.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a vending machine,
The present invention relates to an in-compartment lighting device provided in an inner door for easily illuminating the inside of a room.

[0002]

2. Description of the Related Art In a vending machine for selling products such as canned drinks, a heat-insulating wall forms an inside of a main body case, and a heat-insulating inner door is provided on the front surface of the inside. An interior lighting device is provided on the inner door so that the interior can be easily viewed with the inner door slightly opened. 3 and 4 show this internal lighting device.
Those shown in are known. In the figure, 1 is a heat insulating material 2
An inner door 2 formed by heat insulating walls sandwiched by a plurality of thin iron plates and having an A-side facing the inside of the refrigerator is an inside illumination device configured as follows. That is, a small chamber 5 is formed by cutting out a part of the inner door 1 and inserting a box-shaped frame body 4 having a light projecting window 3 in the bottom plate from the outside so that the light projecting window 3 is on the inside. It A cover 7 to which a heat insulating dew-proof material 6 is attached is detachably provided at the outer opening of the small chamber 5, and a lamp 8 is arranged in the small chamber 5. Then, the light of the lamp 8 illuminates the inside of the refrigerator through the light projecting window 3.

[0003]

By the way, in the conventional interior lighting device 2, the cover 7 is provided so that the inner door 1 does not have a low heat insulating property in the portion where the small chamber 5 is formed and the surface of the cover 7 is not condensed by the outside air. The surface has to be covered with a heat-insulating dew-proofing material, and care must be taken not to damage the coating when attaching or detaching, and the construction and handling are very troublesome.

It is an object of the present invention to provide an interior lighting device of a vending machine which does not require the cover to be covered with a dew-proof material and is easy to handle and handle.

[0005]

In order to achieve the above object, according to the present invention, a small chamber is formed inside a heat-insulating inner door that opens and closes a front surface of the chamber as a heat-insulating chamber, and a lamp is provided in the small chamber. In the interior lighting device of the vending machine configured as described above, a cover that opens and closes the small chamber is provided inside the storage.

[0006]

The cover is provided with a light projecting window and is attached to the inside of the compartment, and a heat insulating wall made of foamed heat insulating material similar to the inner door can be formed on the outside of the small chamber. Therefore, the structure is simple and no special care is required in handling the cover.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 show an embodiment of the present invention, in which parts common or identical to those in FIGS. 3 and 4 are designated by the same reference numerals. In FIGS. 1 and 2, the frame 4 is formed in a box shape with an opening inside, and fixed legs 41 are integrally formed on the top and bottom, and a locking groove is provided between the front and rear projections 42 on the lower edge of the opening. 43 is formed, and a locking claw 45 is provided together with the protrusion 44 on the upper edge of the opening. The frame body 4 is housed in the mold when two thin iron plates are mounted in the mold and synthetic resin is injected and foamed between them to form the heat insulating wall of the inner door 1. Is integrally fixed to the inner door 1 and a heat insulating wall is formed by injecting synthetic resin also on the outside of the bottom plate. The cover 7 is formed of a thin plate whose central portion has a circular cross section, and the light projecting window 3 is provided in the central portion.

In the above structure, the small chamber 5 is formed in the frame body 4 when the inner door 1 is formed, and the lamp 8 is mounted in the small chamber 5. The cover 7 is detachably mounted on the front surface of the frame body 4 by inserting the lower end into the locking groove 43 and pushing the upper end into the locking claw 45. Since the central portion of this cover projects by utilizing the dead space inside the warehouse in which the product rack 10 is arranged, it does not hinder the configuration inside the warehouse such as the installation of the product rack 10. As described above, according to the present invention, by providing the cover 7 inside the refrigerator,
The heat insulating wall on the outside of the small chamber 5 is formed together with the heat insulating wall of the inner door 1, so that the cover 7 does not need to be covered with the heat insulating and dew-proof material, and the structure is extremely simple. Easy to do without

[0009]

According to the present invention, a small chamber is formed inside a heat-insulating inner door that opens and closes the front surface of the inside of the heat-insulating chamber,
In the inside lighting device of the vending machine in which the lamp is provided in the small chamber, since the cover for opening and closing the small chamber is provided inside the inside, it is necessary to cover the cover with the heat insulating dew-proofing material. Since the structure is eliminated and the structure is extremely simplified, the cover can be easily attached and detached without requiring special care when attaching and detaching the cover, and because the cover can be attached simply by pushing.
